+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+                       51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) 19yy  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) 19yy name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+wpa_supplicant and hostapd v0.6.x
+---------------------------------
+
+Copyright (c) 2002-2007, Jouni Malinen <j@w1.fi> and contributors
+All Rights Reserved.
+
+These program is dual-licensed under both the GPL version 2 and BSD
+license. Either license may be used at your option.
+
+
+This package may include either wpa_supplicant, hostapd, or both. See
+README file respective subdirectories (wpa_supplicant/README or
+hostapd/README) for more details.
+
+Source code files have been moved around in v0.6.x releases and
+compared to earlier releases, the programs are now build by first
+going to a subdirectory (wpa_supplicant or hostapd) and creating
+build configuration (.config) and running 'make' there (for
+Linux/BSD/cygwin builds).

+ChangeLog for hostapd
+
+2009-02-15 - v0.6.8
+	* increased hostapd_cli ping interval to 5 seconds and made this
+	  configurable with a new command line options (-G<seconds>)
+	* driver_nl80211: use Linux socket filter to improve performance
+	* added support for external Registrars with WPS (UPnP transport)
+
+2009-01-06 - v0.6.7
+	* added support for Wi-Fi Protected Setup (WPS)
+	  (hostapd can now be configured to act as an integrated WPS Registrar
+	  and provision credentials for WPS Enrollees using PIN and PBC
+	  methods; external wireless Registrar can configure the AP, but
+	  external WLAN Manager Registrars are not supported); WPS support can
+	  be enabled by adding CONFIG_WPS=y into .config and setting the
+	  runtime configuration variables in hostapd.conf (see WPS section in
+	  the example configuration file); new hostapd_cli commands wps_pin and
+	  wps_pbc are used to configure WPS negotiation; see README-WPS for
+	  more details
+	* added IEEE 802.11n HT capability configuration (ht_capab)
+	* added support for generating Country IE based on nl80211 regulatory
+	  information (added if ieee80211d=1 in configuration)
+	* fixed WEP authentication (both Open System and Shared Key) with
+	  mac80211
+	* added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
+	* added support for using driver_test over UDP socket
+	* changed EAP-GPSK to use the IANA assigned EAP method type 51
+	* updated management frame protection to use IEEE 802.11w/D7.0
+	* fixed retransmission of EAP requests if no response is received
+
+2008-11-23 - v0.6.6
+	* added a new configuration option, wpa_ptk_rekey, that can be used to
+	  enforce frequent PTK rekeying, e.g., to mitigate some attacks against
+	  TKIP deficiencies
+	* updated OpenSSL code for EAP-FAST to use an updated version of the
+	  session ticket overriding API that was included into the upstream
+	  OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
+	  needed with that version anymore)
+	* changed channel flags configuration to read the information from
+	  the driver (e.g., via driver_nl80211 when using mac80211) instead of
+	  using hostapd as the source of the regulatory information (i.e.,
+	  information from CRDA is now used with mac80211); this allows 5 GHz
+	  channels to be used with hostapd (if allowed in the current
+	  regulatory domain)
+	* fixed EAP-TLS message processing for the last TLS message if it is
+	  large enough to require fragmentation (e.g., if a large Session
+	  Ticket data is included)
+	* fixed listen interval configuration for nl80211 drivers
+
+2008-11-01 - v0.6.5
+	* added support for SHA-256 as X.509 certificate digest when using the
+	  internal X.509/TLSv1 implementation
+	* fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer
+	  identity lengths)
+	* fixed internal TLSv1 implementation for abbreviated handshake (used
+	  by EAP-FAST server)
+	* added support for setting VLAN ID for STAs based on local MAC ACL
+	  (accept_mac_file) as an alternative for RADIUS server-based
+	  configuration
+	* updated management frame protection to use IEEE 802.11w/D6.0
+	  (adds a new association ping to protect against unauthenticated
+	  authenticate or (re)associate request frames dropping association)
+	* added support for using SHA256-based stronger key derivation for WPA2
+	  (IEEE 802.11w)
+	* added new "driver wrapper" for RADIUS-only configuration
+	  (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config)
+	* fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2)
+	  is enabled in configuration
+	* changed EAP-FAST configuration to use separate fields for A-ID and
+	  A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed
+	  16-octet len binary value for better interoperability with some peer
+	  implementations; eap_fast_a_id is now configured as a hex string
+	* driver_nl80211: Updated to match the current Linux mac80211 AP mode
+	  configuration (wireless-testing.git and Linux kernel releases
+	  starting from 2.6.29)
+
+2008-08-10 - v0.6.4
+	* added peer identity into EAP-FAST PAC-Opaque and skip Phase 2
+	  Identity Request if identity is already known
+	* added support for EAP Sequences in EAP-FAST Phase 2
+	* added support for EAP-TNC (Trusted Network Connect)
+	  (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST
+	  changes needed to run two methods in sequence (IF-T) and the IF-IMV
+	  and IF-TNCCS interfaces from TNCS)
+	* added support for optional cryptobinding with PEAPv0
+	* added fragmentation support for EAP-TNC
+	* added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled)
+	  data
+	* added support for opportunistic key caching (OKC)
+
+2008-02-22 - v0.6.3
+	* fixed Reassociation Response callback processing when using internal
+	  MLME (driver_{hostap,nl80211,test}.c)
+	* updated FT support to use the latest draft, IEEE 802.11r/D9.0
+	* copy optional Proxy-State attributes into RADIUS response when acting
+	  as a RADIUS authentication server
+	* fixed EAPOL state machine to handle a case in which no response is
+	  received from the RADIUS authentication server; previous version
+	  could have triggered a crash in some cases after a timeout
+	* fixed EAP-SIM/AKA realm processing to allow decorated usernames to
+	  be used
+	* added a workaround for EAP-SIM/AKA peers that include incorrect null
+	  termination in the username
+	* fixed EAP-SIM/AKA protected result indication to include AT_COUNTER
+	  attribute in notification messages only when using fast
+	  reauthentication
+	* fixed EAP-SIM Start response processing for fast reauthentication
+	  case
+	* added support for pending EAP processing in EAP-{PEAP,TTLS,FAST}
+	  phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method
+
+2008-01-01 - v0.6.2
+	* fixed EAP-SIM and EAP-AKA message parser to validate attribute
+	  lengths properly to avoid potential crash caused by invalid messages
+	* added data structure for storing allocated buffers (struct wpabuf);
+	  this does not affect hostapd usage, but many of the APIs changed
+	  and various interfaces (e.g., EAP) is not compatible with old
+	  versions
+	* added support for protecting EAP-AKA/Identity messages with
+	  AT_CHECKCODE (optional feature in RFC 4187)
+	* added support for protected result indication with AT_RESULT_IND for
+	  EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1)
+	* added support for configuring EAP-TTLS phase 2 non-EAP methods in
+	  EAP server configuration; previously all four were enabled for every
+	  phase 2 user, now all four are disabled by default and need to be
+	  enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP,
+	  TTLS-MSCHAPV2
+	* removed old debug printing mechanism and the related 'debug'
+	  parameter in the configuration file; debug verbosity is now set with
+	  -d (or -dd) command line arguments
+	* added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
+	  only shared key/password authentication is supported in this version
+
+2007-11-24 - v0.6.1
+	* added experimental, integrated TLSv1 server implementation with the
+	  needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
+	  setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
+	  .config); this can be useful, e.g., if the target system does not
+	  have a suitable TLS library and a minimal code size is required
+	* added support for EAP-FAST server method to the integrated EAP
+	  server
+	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
+	  draft (draft-ietf-emu-eap-gpsk-07.txt)
+	* added a new configuration parameter, rsn_pairwise, to allow different
+	  pairwise cipher suites to be enabled for WPA and RSN/WPA2
+	  (note: if wpa_pairwise differs from rsn_pairwise, the driver will
+	  either need to support this or will have to use the WPA/RSN IEs from
+	  hostapd; currently, the included madwifi and bsd driver interfaces do
+	  not have support for this)
+	* updated FT support to use the latest draft, IEEE 802.11r/D8.0
+
+2007-05-28 - v0.6.0
+	* added experimental IEEE 802.11r/D6.0 support
+	* updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
+	* updated EAP-PSK to use the IANA-allocated EAP type 47
+	* fixed EAP-PSK bit ordering of the Flags field
+	* fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
+	  by reading wpa_psk_file [Bug 181]
+	* fixed EAP-TTLS AVP parser processing for too short AVP lengths
+	* fixed IPv6 connection to RADIUS accounting server
+	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
+	  draft (draft-ietf-emu-eap-gpsk-04.txt)
+	* hlr_auc_gw: read GSM triplet file into memory and rotate through the
+	  entries instead of only using the same three triplets every time
+	  (this does not work properly with tests using multiple clients, but
+	  provides bit better triplet data for testing a single client; anyway,
+	  if a better quality triplets are needed, GSM-Milenage should be used
+	  instead of hardcoded triplet file)
+	* fixed EAP-MSCHAPv2 server to use a space between S and M parameters
+	  in Success Request [Bug 203]
+	* added support for sending EAP-AKA Notifications in error cases
+	* updated to use IEEE 802.11w/D2.0 for management frame protection
+	  (still experimental)
+	* RADIUS server: added support for processing duplicate messages
+	  (retransmissions from RADIUS client) by replying with the previous
+	  reply
+
+2006-11-24 - v0.5.6
+	* added support for configuring and controlling multiple BSSes per
+	  radio interface (bss=<ifname> in hostapd.conf); this is only
+	  available with Devicescape and test driver interfaces
+	* fixed PMKSA cache update in the end of successful RSN
+	  pre-authentication
+	* added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
+	  for each STA based on RADIUS Access-Accept attributes); this requires
+	  VLAN support from the kernel driver/802.11 stack and this is
+	  currently only available with Devicescape and test driver interfaces
+	* driver_madwifi: fixed configuration of unencrypted modes (plaintext
+	  and IEEE 802.1X without WEP)
+	* removed STAKey handshake since PeerKey handshake has replaced it in
+	  IEEE 802.11ma and there are no known deployments of STAKey
+	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
+	  draft (draft-ietf-emu-eap-gpsk-01.txt)
+	* added preliminary implementation of IEEE 802.11w/D1.0 (management
+	  frame protection)
+	  (Note: this requires driver support to work properly.)
+	  (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
+	* hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
+	* hlr_auc_gw: added support for reading per-IMSI Milenage keys and
+	  parameters from a text file to make it possible to implement proper
+	  GSM/UMTS authentication server for multiple SIM/USIM cards using
+	  EAP-SIM/EAP-AKA
+	* fixed session timeout processing with drivers that do not use
+	  ieee802_11.c (e.g., madwifi)
+
+2006-08-27 - v0.5.5
+	* added 'hostapd_cli new_sta <addr>' command for adding a new STA into
+	  hostapd (e.g., to initialize wired network authentication based on an
+	  external signal)
+	* fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
+	  using WPA2 even if PMKSA caching is not used
+	* added -P<pid file> argument for hostapd to write the current process
+	  id into a file
+	* added support for RADIUS Authentication Server MIB (RFC 2619)
+
+2006-06-20 - v0.5.4
+	* fixed nt_password_hash build [Bug 144]
+	* added PeerKey handshake implementation for IEEE 802.11e
+	  direct link setup (DLS) to replace STAKey handshake
+	* added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
+	  draft-clancy-emu-eap-shared-secret-00.txt)
+	* fixed a segmentation fault when RSN pre-authentication was completed
+	  successfully [Bug 152]
+
+2006-04-27 - v0.5.3
+	* do not build nt_password_hash and hlr_auc_gw by default to avoid
+	  requiring a TLS library for a successful build; these programs can be
+	  build with 'make nt_password_hash' and 'make hlr_auc_gw'
+	* added a new configuration option, eapol_version, that can be used to
+	  set EAPOL version to 1 (default is 2) to work around broken client
+	  implementations that drop EAPOL frames which use version number 2
+	  [Bug 89]
+	* added support for EAP-SAKE (no EAP method number allocated yet, so
+	  this is using the same experimental type 255 as EAP-PSK)
+	* fixed EAP-MSCHAPv2 message length validation
+
+2006-03-19 - v0.5.2
+	* fixed stdarg use in hostapd_logger(): if both stdout and syslog
+	  logging was enabled, hostapd could trigger a segmentation fault in
+	  vsyslog on some CPU -- C library combinations
+	* moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
+	  program to make it easier to use for implementing real SS7 gateway;
+	  eap_sim_db is not anymore used as a file name for GSM authentication
+	  triplets; instead, it is path to UNIX domain socket that will be used
+	  to communicate with the external gateway program (e.g., hlr_auc_gw)
+	* added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
+	  local information (GSM authentication triplets from a text file and
+	  hardcoded AKA authentication data); this can be used to test EAP-SIM
+	  and EAP-AKA
+	* added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
+	  to make it possible to test EAP-AKA with real USIM cards (this is
+	  disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
+	  to enable this)
+	* driver_madwifi: added support for getting station RSN IE from
+	  madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
+	  broken with earlier change (r1357) in the driver
+	* changed EAP method registration to use a dynamic list of methods
+	  instead of a static list generated at build time
+	* fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
+	  [Bug 125]
+	* added ap_max_inactivity configuration parameter
+
+2006-01-29 - v0.5.1
+	* driver_test: added better support for multiple APs and STAs by using
+	  a directory with sockets that include MAC address for each device in
+	  the name (test_socket=DIR:/tmp/test)
+	* added support for EAP expanded type (vendor specific EAP methods)
+
+2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
+	* added experimental STAKey handshake implementation for IEEE 802.11e
+	  direct link setup (DLS); note: this is disabled by default in both
+	  build and runtime configuration (can be enabled with CONFIG_STAKEY=y
+	  and stakey=1)
+	* added support for EAP methods to use callbacks to external programs
+	  by buffering a pending request and processing it after the EAP method
+	  is ready to continue
+	* improved EAP-SIM database interface to allow external request to GSM
+	  HLR/AuC without blocking hostapd process
+	* added support for using EAP-SIM pseudonyms and fast re-authentication
+	* added support for EAP-AKA in the integrated EAP authenticator
+	* added support for matching EAP identity prefixes (e.g., "1"*) in EAP
+	  user database to allow EAP-SIM/AKA selection without extra roundtrip
+	  for EAP-Nak negotiation
+	* added support for storing EAP user password as NtPasswordHash instead
+	  of plaintext password when using MSCHAP or MSCHAPv2 for
+	  authentication (hash:<16-octet hex value>); added nt_password_hash
+	  tool for hashing password to generate NtPasswordHash
+
+2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
+	* driver_wired: fixed EAPOL sending to optionally use PAE group address
+	  as the destination instead of supplicant MAC address; this is
+	  disabled by default, but should be enabled with use_pae_group_addr=1
+	  in configuration file if the wired interface is used by only one
+	  device at the time (common switch configuration)
+	* driver_madwifi: configure driver to use TKIP countermeasures in order
+	  to get correct behavior (IEEE 802.11 association failing; previously,
+	  association succeeded, but hostpad forced disassociation immediately)
+	* driver_madwifi: added support for madwifi-ng
+
+2005-10-27 - v0.4.6
+	* added support for replacing user identity from EAP with RADIUS
+	  User-Name attribute from Access-Accept message, if that is included,
+	  for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
+	  tunneled identity into accounting messages when the RADIUS server
+	  does not support better way of doing this with Class attribute)
+	* driver_madwifi: fixed EAPOL packet receive for configuration where
+	  ath# is part of a bridge interface
+	* added a configuration file and log analyzer script for logwatch
+	* fixed EAPOL state machine step function to process all state
+	  transitions before processing new events; this resolves a race
+	  condition in which EAPOL-Start message could trigger hostapd to send
+	  two EAP-Response/Identity frames to the authentication server
+
+2005-09-25 - v0.4.5
+	* added client CA list to the TLS certificate request in order to make
+	  it easier for the client to select which certificate to use
+	* added experimental support for EAP-PSK
+	* added support for WE-19 (hostap, madwifi)
+
+2005-08-21 - v0.4.4
+	* fixed build without CONFIG_RSN_PREAUTH
+	* fixed FreeBSD build
+
+2005-06-26 - v0.4.3
+	* fixed PMKSA caching to copy User-Name and Class attributes so that
+	  RADIUS accounting gets correct information
+	* start RADIUS accounting only after successful completion of WPA
+	  4-Way Handshake if WPA-PSK is used
+	* fixed PMKSA caching for the case where STA (re)associates without
+	  first disassociating
+
+2005-06-12 - v0.4.2
+	* EAP-PAX is now registered as EAP type 46
+	* fixed EAP-PAX MAC calculation
+	* fixed EAP-PAX CK and ICK key derivation
+	* renamed eap_authenticator configuration variable to eap_server to
+	  better match with RFC 3748 (EAP) terminology
+	* driver_test: added support for testing hostapd with wpa_supplicant
+	  by using test driver interface without any kernel drivers or network
+	  cards
+
+2005-05-22 - v0.4.1
+	* fixed RADIUS server initialization when only auth or acct server
+	  is configured and the other one is left empty
+	* driver_madwifi: added support for RADIUS accounting
+	* driver_madwifi: added preliminary support for compiling against 'BSD'
+	  branch of madwifi CVS tree
+	* driver_madwifi: fixed pairwise key removal to allow WPA reauth
+	  without disassociation
+	* added support for reading additional certificates from PKCS#12 files
+	  and adding them to the certificate chain
+	* fixed RADIUS Class attribute processing to only use Access-Accept
+	  packets to update Class; previously, other RADIUS authentication
+	  packets could have cleared Class attribute
+	* added support for more than one Class attribute in RADIUS packets
+	* added support for verifying certificate revocation list (CRL) when
+	  using integrated EAP authenticator for EAP-TLS; new hostapd.conf
+	  options 'check_crl'; CRL must be included in the ca_cert file for now
+
+2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
+	* added support for including network information into
+	  EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
+	  (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
+	* fixed a bug which caused some RSN pre-authentication cases to use
+	  freed memory and potentially crash hostapd
+	* fixed private key loading for cases where passphrase is not set
+	* added support for sending TLS alerts and aborting authentication
+	  when receiving a TLS alert
+	* fixed WPA2 to add PMKSA cache entry when using integrated EAP
+	  authenticator
+	* fixed PMKSA caching (EAP authentication was not skipped correctly
+	  with the new state machine changes from IEEE 802.1X draft)
+	* added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
+	  and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
+	  to be added to .config to include IPv6 support); for RADIUS server,
+	  radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
+	  in RADIUS clients file can then use IPv6 format
+	* added experimental support for EAP-PAX
+	* replaced hostapd control interface library (hostapd_ctrl.[ch]) with
+	  the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
+
+2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
+
+2005-01-23 - v0.3.5
+	* added support for configuring a forced PEAP version based on the
+	  Phase 1 identity
+	* fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
+	  to terminate authentication
+	* fixed EAP identifier duplicate processing with the new IEEE 802.1X
+	  draft
+	* clear accounting data in the driver when starting a new accounting
+	  session
+	* driver_madwifi: filter wireless events based on ifindex to allow more
+	  than one network interface to be used
+	* fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
+	  setting if the packet does not pass MIC verification (e.g., due to
+	  incorrect PSK); previously, message 1/4 was not tried again if an
+	  invalid message 2/4 was received
+	* fixed reconfiguration of RADIUS client retransmission timer when
+	  adding a new message to the pending list; previously, timer was not
+	  updated at this point and if there was a pending message with long
+	  time for the next retry, the new message needed to wait that long for
+	  its first retry, too
+
+2005-01-09 - v0.3.4
+	* added support for configuring multiple allowed EAP types for Phase 2
+	  authentication (EAP-PEAP, EAP-TTLS)
+	* fixed EAPOL-Start processing to trigger WPA reauthentication
+	  (previously, only EAPOL authentication was done)
+
+2005-01-02 - v0.3.3
+	* added support for EAP-PEAP in the integrated EAP authenticator
+	* added support for EAP-GTC in the integrated EAP authenticator
+	* added support for configuring list of EAP methods for Phase 1 so that
+	  the integrated EAP authenticator can, e.g., use the wildcard entry
+	  for EAP-TLS and EAP-PEAP
+	* added support for EAP-TTLS in the integrated EAP authenticator
+	* added support for EAP-SIM in the integrated EAP authenticator
+	* added support for using hostapd as a RADIUS authentication server
+	  with the integrated EAP authenticator taking care of EAP
+	  authentication (new hostapd.conf options: radius_server_clients and
+	  radius_server_auth_port); this is not included in default build; use
+	  CONFIG_RADIUS_SERVER=y in .config to include
+
+2004-12-19 - v0.3.2
+	* removed 'daemonize' configuration file option since it has not really
+	  been used at all for more than year
+	* driver_madwifi: fixed group key setup and added get_ssid method
+	* added support for EAP-MSCHAPv2 in the integrated EAP authenticator
+
+2004-12-12 - v0.3.1
+	* added support for integrated EAP-TLS authentication (new hostapd.conf
+	  variables: ca_cert, server_cert, private_key, private_key_passwd);
+	  this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
+	  external RADIUS server
+	* added support for reading PKCS#12 (PFX) files (as a replacement for
+	  PEM/DER) to get certificate and private key (CONFIG_PKCS12)
+
+2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
+	* added support for Acct-{Input,Output}-Gigawords
+	* added support for Event-Timestamp (in RADIUS Accounting-Requests)
+	* added support for RADIUS Authentication Client MIB (RFC2618)
+	* added support for RADIUS Accounting Client MIB (RFC2620)
+	* made EAP re-authentication period configurable (eap_reauth_period)
+	* fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
+	* fixed EAPOL state machine to stop if STA is removed during
+	  eapol_sm_step(); this fixes at least one segfault triggering bug with
+	  IEEE 802.11i pre-authentication
+	* added support for multiple WPA pre-shared keys (e.g., one for each
+	  client MAC address or keys shared by a group of clients);
+	  new hostapd.conf field wpa_psk_file for setting path to a text file
+	  containing PSKs, see hostapd.wpa_psk for an example
+	* added support for multiple driver interfaces to allow hostapd to be
+	  used with other drivers
+	* added wired authenticator driver interface (driver=wired in
+	  hostapd.conf, see wired.conf for example configuration)
+	* added madwifi driver interface (driver=madwifi in hostapd.conf, see
+	  madwifi.conf for example configuration; Note: include files from
+	  madwifi project is needed for building and a configuration file,
+	  .config, needs to be created in hostapd directory with
+	  CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
+	  build)
+	* fixed an alignment issue that could cause SHA-1 to fail on some
+	  platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
+	  align variables)
+	* fixed RADIUS reconnection after an error in sending interim
+	  accounting packets
+	* added hostapd control interface for external programs and an example
+	  CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
+	* started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
+	  'hostapd_cli sta <addr>')
+	* finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
+	* added support for strict GTK rekeying (wpa_strict_rekey in
+	  hostapd.conf)
+	* updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
+	  (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
+	  IEEE 802.11F-2003)
+	* added Prism54 driver interface (driver=prism54 in hostapd.conf;
+	  note: .config needs to be created in hostapd directory with
+	  CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
+	  build)
+	* dual-licensed hostapd (GPLv2 and BSD licenses)
+	* fixed RADIUS accounting to generate a new session id for cases where
+	  a station reassociates without first being complete deauthenticated
+	* fixed STA disassociation handler to mark next timeout state to
+	  deauthenticate the station, i.e., skip long wait for inactivity poll
+	  and extra disassociation, if the STA disassociates without
+	  deauthenticating
+	* added integrated EAP authenticator that can be used instead of
+	  external RADIUS authentication server; currently, only EAP-MD5 is
+	  supported, so this cannot yet be used for key distribution; the EAP
+	  method interface is generic, though, so adding new EAP methods should
+	  be straightforward; new hostapd.conf variables: 'eap_authenticator'
+	  and 'eap_user_file'; this obsoletes "minimal authentication server"
+	  ('minimal_eap' in hostapd.conf) which is now removed
+	* added support for FreeBSD and driver interface for the BSD net80211
+	  layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
+	  .config); please note that some of the required kernel mods have not
+	  yet been committed
+
+2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
+	* fixed some accounting cases where Accounting-Start was sent when
+	  IEEE 802.1X port was being deauthorized
+
+2004-06-20 - v0.2.3
+	* modified RADIUS client to re-connect the socket in case of certain
+	  error codes that are generated when a network interface state is
+	  changes (e.g., when IP address changes or the interface is set UP)
+	* fixed couple of cases where EAPOL state for a station was freed
+	  twice causing a segfault for hostapd
+	* fixed couple of bugs in processing WPA deauthentication (freed data
+	  was used)
+
+2004-05-31 - v0.2.2
+	* fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
+	* fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
+	  cases where STAs dropped multicast frames as replay attacks
+	* added support for copying RADIUS Attribute 'Class' from
+	  authentication messages into accounting messages
+	* send canned EAP failure if RADIUS server sends Access-Reject without
+	  EAP message (previously, Supplicant was not notified in this case)
+	* fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
+	  not start EAPOL state machines if the STA selected to use WPA-PSK)
+
+2004-05-06 - v0.2.1
+	* added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
+	  - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
+	    (i.e., IEEE 802.11i/D3.0)
+	  - supports WPA-only, RSN-only, and mixed WPA/RSN mode
+	  - both WPA-PSK and WPA-RADIUS/EAP are supported
+	  - PMKSA caching and pre-authentication
+	  - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
+	    wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
+	    rsn_preauth, rsn_preauth_interfaces
+	* fixed interim accounting to remove any pending accounting messages
+	  to the STA before sending a new one
+
+2004-02-15 - v0.2.0
+	* added support for Acct-Interim-Interval:
+	  - draft-ietf-radius-acct-interim-01.txt
+	  - use Acct-Interim-Interval attribute from Access-Accept if local
+	    'radius_acct_interim_interval' is not set
+	  - allow different update intervals for each STA
+	* fixed event loop to call signal handlers only after returning from
+	  the real signal handler
+	* reset sta->timeout_next after successful association to make sure
+	  that the previously registered inactivity timer will not remove the
+	  STA immediately (e.g., if STA deauthenticates and re-associates
+	  before the timer is triggered).
+	* added new hostapd.conf variable, nas_identifier, that can be used to
+	  add an optional RADIUS Attribute, NAS-Identifier, into authentication
+	  and accounting messages
+	* added support for Accounting-On and Accounting-Off messages
+	* fixed accounting session handling to send Accounting-Start only once
+	  per session and not to send Accounting-Stop if the session was not
+	  initialized properly
+	* fixed Accounting-Stop statistics in cases where the message was
+	  previously sent after the kernel entry for the STA (and/or IEEE
+	  802.1X data) was removed
+
+
+Note:
+
+Older changes up to and including v0.1.0 are included in the ChangeLog
+of the Host AP driver.

+Introduction
+============
+
+Originally, hostapd was an optional user space component for Host AP
+driver. It adds more features to the basic IEEE 802.11 management
+included in the kernel driver: using external RADIUS authentication
+server for MAC address based access control, IEEE 802.1X Authenticator
+and dynamic WEP keying, RADIUS accounting, WPA/WPA2 (IEEE 802.11i/RSN)
+Authenticator and dynamic TKIP/CCMP keying.
+
+The current version includes support for other drivers, an integrated
+EAP server (i.e., allow full authentication without requiring
+an external RADIUS authentication server), and RADIUS authentication
+server for EAP authentication.
+
+
+Requirements
+------------
+
+Current hardware/software requirements:
+- drivers:
+	Host AP driver for Prism2/2.5/3.
+	(http://hostap.epitest.fi/)
+	Please note that station firmware version needs to be 1.7.0 or newer
+	to work in WPA mode.

+
+
+IEEE 802.1X
+===========
+
+IEEE Std 802.1X-2001 is a standard for port-based network access
+control. In case of IEEE 802.11 networks, a "virtual port" is used
+between each associated station and the AP. IEEE 802.11 specifies
+minimal authentication mechanism for stations, whereas IEEE 802.1X
+introduces a extensible mechanism for authenticating and authorizing
+users.
+
+IEEE 802.1X uses elements called Supplicant, Authenticator, Port
+Access Entity, and Authentication Server. Supplicant is a component in
+a station and it performs the authentication with the Authentication
+Server. An access point includes an Authenticator that relays the packets
+between a Supplicant and an Authentication Server. In addition, it has a
+Port Access Entity (PAE) with Authenticator functionality for
+controlling the virtual port authorization, i.e., whether to accept
+packets from or to the station.
+
+IEEE 802.1X uses Extensible Authentication Protocol (EAP). The frames
+between a Supplicant and an Authenticator are sent using EAP over LAN
+(EAPOL) and the Authenticator relays these frames to the Authentication
+Server (and similarly, relays the messages from the Authentication
+Server to the Supplicant). The Authentication Server can be colocated with the
+Authenticator, in which case there is no need for additional protocol
+for EAP frame transmission. However, a more common configuration is to
+use an external Authentication Server and encapsulate EAP frame in the
+frames used by that server. RADIUS is suitable for this, but IEEE
+802.1X would also allow other mechanisms.
+
+Host AP driver includes PAE functionality in the kernel driver. It
+is a relatively simple mechanism for denying normal frames going to
+or coming from an unauthorized port. PAE allows IEEE 802.1X related
+frames to be passed between the Supplicant and the Authenticator even
+on an unauthorized port.
+
+User space daemon, hostapd, includes Authenticator functionality. It
+receives 802.1X (EAPOL) frames from the Supplicant using the wlan#ap
+device that is also used with IEEE 802.11 management frames. The
+frames to the Supplicant are sent using the same device.
+
+The normal configuration of the Authenticator would use an external
+Authentication Server. hostapd supports RADIUS encapsulation of EAP
+packets, so the Authentication Server should be a RADIUS server, like
+FreeRADIUS (http://www.freeradius.org/). The Authenticator in hostapd
+relays the frames between the Supplicant and the Authentication
+Server. It also controls the PAE functionality in the kernel driver by
+controlling virtual port authorization, i.e., station-AP
+connection, based on the IEEE 802.1X state.
+
+When a station would like to use the services of an access point, it
+will first perform IEEE 802.11 authentication. This is normally done
+with open systems authentication, so there is no security. After
+this, IEEE 802.11 association is performed. If IEEE 802.1X is
+configured to be used, the virtual port for the station is set in
+Unauthorized state and only IEEE 802.1X frames are accepted at this
+point. The Authenticator will then ask the Supplicant to authenticate
+with the Authentication Server. After this is completed successfully,
+the virtual port is set to Authorized state and frames from and to the
+station are accepted.
+
+Host AP configuration for IEEE 802.1X
+-------------------------------------
+
+The user space daemon has its own configuration file that can be used to
+define AP options. Distribution package contains an example
+configuration file (hostapd/hostapd.conf) that can be used as a basis
+for configuration. It includes examples of all supported configuration
+options and short description of each option. hostapd should be started
+with full path to the configuration file as the command line argument,
+e.g., './hostapd /etc/hostapd.conf'. If you have more that one wireless
+LAN card, you can use one hostapd process for multiple interfaces by
+giving a list of configuration files (one per interface) in the command
+line.
+
+hostapd includes a minimal co-located IEEE 802.1X server which can be
+used to test IEEE 802.1X authentication. However, it should not be
+used in normal use since it does not provide any security. This can be
+configured by setting ieee8021x and minimal_eap options in the
+configuration file.
+
+An external Authentication Server (RADIUS) is configured with
+auth_server_{addr,port,shared_secret} options. In addition,
+ieee8021x and own_ip_addr must be set for this mode. With such
+configuration, the co-located Authentication Server is not used and EAP
+frames will be relayed using EAPOL between the Supplicant and the
+Authenticator and RADIUS encapsulation between the Authenticator and
+the Authentication Server. Other than this, the functionality is similar
+to the case with the co-located Authentication Server.
+
+Authentication Server and Supplicant
+------------------------------------
+
+Any RADIUS server supporting EAP should be usable as an IEEE 802.1X
+Authentication Server with hostapd Authenticator. FreeRADIUS
+(http://www.freeradius.org/) has been successfully tested with hostapd
+Authenticator and both Xsupplicant (http://www.open1x.org) and Windows
+XP Supplicants. EAP/TLS was used with Xsupplicant and
+EAP/MD5-Challenge with Windows XP.
+
+http://www.missl.cs.umd.edu/wireless/eaptls/ has useful information
+about using EAP/TLS with FreeRADIUS and Xsupplicant (just replace
+Cisco access point with Host AP driver, hostapd daemon, and a Prism2
+card ;-). http://www.freeradius.org/doc/EAP-MD5.html has information
+about using EAP/MD5 with FreeRADIUS, including instructions for WinXP
+configuration. http://www.denobula.com/EAPTLS.pdf has a HOWTO on
+EAP/TLS use with WinXP Supplicant.
+
+Automatic WEP key configuration
+-------------------------------
+
+EAP/TLS generates a session key that can be used to send WEP keys from
+an AP to authenticated stations. The Authenticator in hostapd can be
+configured to automatically select a random default/broadcast key
+(shared by all authenticated stations) with wep_key_len_broadcast
+option (5 for 40-bit WEP or 13 for 104-bit WEP). In addition,
+wep_key_len_unicast option can be used to configure individual unicast
+keys for stations. This requires support for individual keys in the
+station driver.
+
+WEP keys can be automatically updated by configuring rekeying. This
+will improve security of the network since same WEP key will only be
+used for a limited period of time. wep_rekey_period option sets the
+interval for rekeying in seconds.
+
+
+WPA/WPA2
+========
+
+Features
+--------
+
+Supported WPA/IEEE 802.11i features:
+- WPA-PSK ("WPA-Personal")
+- WPA with EAP (e.g., with RADIUS authentication server) ("WPA-Enterprise")
+- key management for CCMP, TKIP, WEP104, WEP40
+- RSN/WPA2 (IEEE 802.11i), including PMKSA caching and pre-authentication
+
+WPA
+---
+
+The original security mechanism of IEEE 802.11 standard was not
+designed to be strong and has proved to be insufficient for most
+networks that require some kind of security. Task group I (Security)
+of IEEE 802.11 working group (http://www.ieee802.org/11/) has worked
+to address the flaws of the base standard and has in practice
+completed its work in May 2004. The IEEE 802.11i amendment to the IEEE
+802.11 standard was approved in June 2004 and this amendment is likely
+to be published in July 2004.
+
+Wi-Fi Alliance (http://www.wi-fi.org/) used a draft version of the
+IEEE 802.11i work (draft 3.0) to define a subset of the security
+enhancements that can be implemented with existing wlan hardware. This
+is called Wi-Fi Protected Access<TM> (WPA). This has now become a
+mandatory component of interoperability testing and certification done
+by Wi-Fi Alliance. Wi-Fi provides information about WPA at its web
+site (http://www.wi-fi.org/OpenSection/protected_access.asp).
+
+IEEE 802.11 standard defined wired equivalent privacy (WEP) algorithm
+for protecting wireless networks. WEP uses RC4 with 40-bit keys,
+24-bit initialization vector (IV), and CRC32 to protect against packet
+forgery. All these choices have proven to be insufficient: key space is
+too small against current attacks, RC4 key scheduling is insufficient
+(beginning of the pseudorandom stream should be skipped), IV space is
+too small and IV reuse makes attacks easier, there is no replay
+protection, and non-keyed authentication does not protect against bit
+flipping packet data.
+
+WPA is an intermediate solution for the security issues. It uses
+Temporal Key Integrity Protocol (TKIP) to replace WEP. TKIP is a
+compromise on strong security and possibility to use existing
+hardware. It still uses RC4 for the encryption like WEP, but with
+per-packet RC4 keys. In addition, it implements replay protection,
+keyed packet authentication mechanism (Michael MIC).
+
+Keys can be managed using two different mechanisms. WPA can either use
+an external authentication server (e.g., RADIUS) and EAP just like
+IEEE 802.1X is using or pre-shared keys without need for additional
+servers. Wi-Fi calls these "WPA-Enterprise" and "WPA-Personal",
+respectively. Both mechanisms will generate a master session key for
+the Authenticator (AP) and Supplicant (client station).
+
+WPA implements a new key handshake (4-Way Handshake and Group Key
+Handshake) for generating and exchanging data encryption keys between
+the Authenticator and Supplicant. This handshake is also used to
+verify that both Authenticator and Supplicant know the master session
+key. These handshakes are identical regardless of the selected key
+management mechanism (only the method for generating master session
+key changes).
+
+
+IEEE 802.11i / WPA2
+-------------------
+
+The design for parts of IEEE 802.11i that were not included in WPA has
+finished (May 2004) and this amendment to IEEE 802.11 was approved in
+June 2004. Wi-Fi Alliance is using the final IEEE 802.11i as a new
+version of WPA called WPA2. This includes, e.g., support for more
+robust encryption algorithm (CCMP: AES in Counter mode with CBC-MAC)
+to replace TKIP and optimizations for handoff (reduced number of
+messages in initial key handshake, pre-authentication, and PMKSA caching).
+
+Some wireless LAN vendors are already providing support for CCMP in
+their WPA products. There is no "official" interoperability
+certification for CCMP and/or mixed modes using both TKIP and CCMP, so
+some interoperability issues can be expected even though many
+combinations seem to be working with equipment from different vendors.
+Testing for WPA2 is likely to start during the second half of 2004.

+hostapd and Wi-Fi Protected Setup (WPS)
+=======================================
+
+This document describes how the WPS implementation in hostapd can be
+configured and how an external component on an AP (e.g., web UI) is
+used to enable enrollment of client devices.
+
+
+Introduction to WPS
+-------------------
+
+Wi-Fi Protected Setup (WPS) is a mechanism for easy configuration of a
+wireless network. It allows automated generation of random keys (WPA
+passphrase/PSK) and configuration of an access point and client
+devices. WPS includes number of methods for setting up connections
+with PIN method and push-button configuration (PBC) being the most
+commonly deployed options.
+
+While WPS can enable more home networks to use encryption in the
+wireless network, it should be noted that the use of the PIN and
+especially PBC mechanisms for authenticating the initial key setup is
+not very secure. As such, use of WPS may not be suitable for
+environments that require secure network access without chance for
+allowing outsiders to gain access during the setup phase.
+
+WPS uses following terms to describe the entities participating in the
+network setup:
+- access point: the WLAN access point
+- Registrar: a device that control a network and can authorize
+  addition of new devices); this may be either in the AP ("internal
+  Registrar") or in an external device, e.g., a laptop, ("external
+  Registrar")
+- Enrollee: a device that is being authorized to use the network
+
+It should also be noted that the AP and a client device may change
+roles (i.e., AP acts as an Enrollee and client device as a Registrar)
+when WPS is used to configure the access point.
+
+
+More information about WPS is available from Wi-Fi Alliance:
+http://www.wi-fi.org/wifi-protected-setup
+
+
+hostapd implementation
+----------------------
+
+hostapd includes an optional WPS component that can be used as an
+internal WPS Registrar to manage addition of new WPS enabled clients
+to the network. In addition, WPS Enrollee functionality in hostapd can
+be used to allow external WPS Registrars to configure the access
+point, e.g., for initial network setup. In addition, hostapd can proxy a
+WPS registration between a wireless Enrollee and an external Registrar
+(e.g., Microsoft Vista or Atheros JumpStart) with UPnP.
+
+
+hostapd configuration
+---------------------
+
+WPS is an optional component that needs to be enabled in hostapd build
+configuration (.config). Here is an example configuration that
+includes WPS support and uses madwifi driver interface:
+
+CONFIG_DRIVER_MADWIFI=y
+CFLAGS += -I/usr/src/madwifi-0.9.3
+CONFIG_EAP=y
+CONFIG_WPS=y
+CONFIG_WPS_UPNP=y
+
+
+Following section shows an example runtime configuration
+(hostapd.conf) that enables WPS:
+
+# Configure the driver and network interface
+driver=madwifi
+interface=ath0
+
+# WPA2-Personal configuration for the AP
+ssid=wps-test
+wpa=2
+wpa_key_mgmt=WPA-PSK
+wpa_pairwise=CCMP
+# Default WPA passphrase for legacy (non-WPS) clients
+wpa_passphrase=12345678
+# Enable random per-device PSK generation for WPS clients
+# Please note that the file has to exists for hostapd to start (i.e., create an
+# empty file as a starting point).
+wpa_psk_file=/etc/hostapd.psk
+
+# Enable control interface for PBC/PIN entry
+ctrl_interface=/var/run/hostapd
+
+# Enable internal EAP server for EAP-WSC (part of Wi-Fi Protected Setup)
+eap_server=1
+
+# WPS configuration (AP configured, do not allow external WPS Registrars)
+wps_state=2
+ap_setup_locked=1
+# If UUID is not configured, it will be generated based on local MAC address.
+uuid=87654321-9abc-def0-1234-56789abc0000
+wps_pin_requests=/var/run/hostapd.pin-req
+device_name=Wireless AP
+manufacturer=Company
+model_name=WAP
+model_number=123
+serial_number=12345
+device_type=6-0050F204-1
+os_version=01020300
+config_methods=label display push_button keypad
+
+# if external Registrars are allowed, UPnP support could be added:
+#upnp_iface=br0
+#friendly_name=WPS Access Point
+
+
+External operations
+-------------------
+
+WPS requires either a device PIN code (usually, 8-digit number) or a
+pushbutton event (for PBC) to allow a new WPS Enrollee to join the
+network. hostapd uses the control interface as an input channel for
+these events.
+
+When a client device (WPS Enrollee) connects to hostapd (WPS
+Registrar) in order to start PIN mode negotiation for WPS, an
+identifier (Enrollee UUID) is sent. hostapd will need to be configured
+with a device password (PIN) for this Enrollee. This is an operation
+that requires user interaction (assuming there are no pre-configured
+PINs on the AP for a set of Enrollee).
+
+The PIN request with information about the device is appended to the
+wps_pin_requests file (/var/run/hostapd.pin-req in this example). In
+addition, hostapd control interface event is sent as a notification of
+a new device. The AP could use, e.g., a web UI for showing active
+Enrollees to the user and request a PIN for an Enrollee.
+
+The PIN request file has one line for every Enrollee that connected to
+the AP, but for which there was no PIN. Following information is
+provided for each Enrollee (separated with tabulators):
+- timestamp (seconds from 1970-01-01)
+- Enrollee UUID
+- MAC address
+- Device name
+- Manufacturer
+- Model Name
+- Model Number
+- Serial Number
+- Device category
+
+Example line in the /var/run/hostapd.pin-req file:
+1200188391	53b63a98-d29e-4457-a2ed-094d7e6a669c	Intel(R) Centrino(R)	Intel Corporation	Intel(R) Centrino(R)	-	-	1-0050F204-1
+
+Control interface data:
+WPS-PIN-NEEDED [UUID-E|MAC Address|Device Name|Manufacturer|Model Name|Model Number|Serial Number|Device Category]
+For example:
+<2>WPS-PIN-NEEDED [53b63a98-d29e-4457-a2ed-094d7e6a669c|02:12:34:56:78:9a|Device|Manuf|Model|Model Number|Serial Number|1-0050F204-1]
+
+When the user enters a PIN for a pending Enrollee, e.g., on the web
+UI), hostapd needs to be notified of the new PIN over the control
+interface. This can be done either by using the UNIX domain socket
+-based control interface directly (src/common/wpa_ctrl.c provides
+helper functions for using the interface) or by calling hostapd_cli.
+
+Example command to add a PIN (12345670) for an Enrollee:
+
+hostapd_cli wps_pin 53b63a98-d29e-4457-a2ed-094d7e6a669c 12345670
+
+If the UUID-E is not available (e.g., Enrollee waits for the Registrar
+to be selected before connecting), wildcard UUID may be used to allow the PIN to be used once with any UUID:
+
+hostapd_cli wps_pin any 12345670
+
+
+After this, the Enrollee can connect to the AP again and complete WPS
+negotiation. At that point, a new, random WPA PSK is generated for the
+client device and the client can then use that key to connect to the
+AP to access the network.
+
+
+If the AP includes a pushbutton, WPS PBC mode can be used. It is
+enabled by pushing a button on both the AP and the client at about the
+same time (2 minute window). hostapd needs to be notified about the AP
+button pushed event over the control interface, e.g., by calling
+hostapd_cli:
+
+hostapd_cli wps_pbc
+
+At this point, the client has two minutes to complete WPS negotiation
+which will generate a new WPA PSK in the same way as the PIN method
+described above.
+
+
+Credential generation and configuration changes
+-----------------------------------------------
+
+By default, hostapd generates credentials for Enrollees and processing
+AP configuration updates internally. However, it is possible to
+control these operations from external programs, if desired.
+
+The internal credential generation can be disabled with
+skip_cred_build=1 option in the configuration. extra_cred option will
+then need to be used to provide pre-configured Credential attribute(s)
+for hostapd to use. The exact data from this binary file will be sent,
+i.e., it will have to include valid WPS attributes. extra_cred can
+also be used to add additional networks if the Registrar is used to
+configure credentials for multiple networks.
+
+Processing of received configuration updates can be disabled with
+wps_cred_processing=1 option. When this is used, an external program
+is responsible for creating hostapd configuration files and processing
+configuration updates based on messages received from hostapd over
+control interface. This will also include the initial configuration on
+first successful registration if the AP is initially set in
+unconfigured state.
+
+Following control interface messages are sent out for external programs:
+
+WPS-REG-SUCCESS <Enrollee MAC address <UUID-E>
+For example:
+<2>WPS-REG-SUCCESS 02:66:a0:ee:17:27 2b7093f1-d6fb-5108-adbb-bea66bb87333
+
+This can be used to tricker change from unconfigured to configured
+state (random configuration based on the first successful WPS
+registration). In addition, this can be used to update AP UI about the
+status of WPS registration progress.
+
+
+WPS-NEW-AP-SETTINGS <hexdump of AP Setup attributes>
+For example:
+<2>WPS-NEW-AP-SETTINGS 10260001011045000c6a6b6d2d7770732d74657374100300020020100f00020008102700403065346230343536633236366665306433396164313535346131663462663731323433376163666462376633393965353466316631623032306164343438623510200006024231cede15101e000844
+
+This can be used to update the externally stored AP configuration and
+then update hostapd configuration (followed by restarting of hostapd).

+/**
+\page ctrl_iface_page Control interface
+
+hostapd implements a control interface that can be used by
+external programs to control the operations of the hostapd
+daemon and to get status information and event notifications. There is
+a small C library, in a form of a single C file, wpa_ctrl.c, that
+provides helper functions to facilitate the use of the control
+interface. External programs can link this file into them and then use
+the library functions documented in wpa_ctrl.h to interact with
+%wpa_supplicant. This library can also be used with C++. hostapd_cli.c
+is an example program using this library.
+
+There are multiple mechanisms for inter-process communication. For
+example, Linux version of hostapd is using UNIX domain sockets for the
+control interface. The use of the functions defined in wpa_ctrl.h can
+be used to hide the details of the used IPC from external programs.
+
+
+\section using_ctrl_iface Using the control interface
+
+External programs, e.g., a GUI or a configuration utility, that need to
+communicate with hostapd should link in wpa_ctrl.c. This
+allows them to use helper functions to open connection to the control
+interface with wpa_ctrl_open() and to send commands with
+wpa_ctrl_request().
+
+hostapd uses the control interface for two types of communication:
+commands and unsolicited event messages. Commands are a pair of
+messages, a request from the external program and a response from
+hostapd. These can be executed using wpa_ctrl_request().
+Unsolicited event messages are sent by hostapd to the control
+interface connection without specific request from the external program
+for receiving each message. However, the external program needs to
+attach to the control interface with wpa_ctrl_attach() to receive these
+unsolicited messages.
+
+If the control interface connection is used both for commands and
+unsolicited event messages, there is potential for receiving an
+unsolicited message between the command request and response.
+wpa_ctrl_request() caller will need to supply a callback, msg_cb,
+for processing these messages. Often it is easier to open two
+control interface connections by calling wpa_ctrl_open() twice and
+then use one of the connections for commands and the other one for
+unsolicited messages. This way command request/response pairs will
+not be broken by unsolicited messages. wpa_cli is an example of how
+to use only one connection for both purposes and wpa_gui demonstrates
+how to use two separate connections.
+
+Once the control interface connection is not needed anymore, it should
+be closed by calling wpa_ctrl_close(). If the connection was used for
+unsolicited event messages, it should be first detached by calling
+wpa_ctrl_detach().
+
+
+\section ctrl_iface_cmds Control interface commands
+
+Following commands can be used with wpa_ctrl_request():
+
+\subsection ctrl_iface_PING PING
+
+This command can be used to test whether hostapd is replying
+to the control interface commands. The expected reply is \c PONG if the
+connection is open and hostapd is processing commands.

+/**
+\page driver_wrapper Driver wrapper implementation (driver.h, drivers.c)
+
+All hardware and driver dependent functionality is in separate C files
+that implement defined wrapper functions. Other parts
+of the hostapd are designed to be hardware, driver, and operating
+system independent.
+
+Driver wrappers need to implement whatever calls are used in the
+target operating system/driver for controlling wireless LAN
+devices. As an example, in case of Linux, these are mostly some glue
+code and ioctl() calls and netlink message parsing for Linux Wireless
+Extensions (WE). Since features required for WPA were added only recently to
+Linux Wireless Extensions (in version 18), some driver specific code is used
+in number of driver interface implementations. These driver dependent parts
+can be replaced with generic code in driver_wext.c once the target driver
+includes full support for WE-18. After that, all Linux drivers, at
+least in theory, could use the same driver wrapper code.

+/**
+\page eap_module EAP server implementation
+
+Extensible Authentication Protocol (EAP) is an authentication framework
+defined in RFC 3748. hostapd uses a separate code module for EAP server
+implementation. This module was designed to use only a minimal set of
+direct function calls (mainly, to debug/event functions) in order for
+it to be usable in other programs. The design of the EAP
+implementation is based loosely on RFC 4137. The state machine is
+defined in this RFC and so is the interface between the server state
+machine and methods. As such, this RFC provides useful information for
+understanding the EAP server implementation in hostapd.
+
+Some of the terminology used in EAP state machine is referring to
+EAPOL (IEEE 802.1X), but there is no strict requirement on the lower
+layer being IEEE 802.1X if EAP module is built for other programs than
+%wpa_supplicant. These terms should be understood to refer to the
+lower layer as defined in RFC 4137.
+
+
+\section adding_eap_methods Adding EAP methods
+
+Each EAP method is implemented as a separate module, usually as one C
+file named eap_<name of the method>.c, e.g., eap_md5.c. All EAP
+methods use the same interface between the server state machine and
+method specific functions. This allows new EAP methods to be added
+without modifying the core EAP state machine implementation.
+
+New EAP methods need to be registered by adding them into the build
+(Makefile) and the EAP method registration list in the
+eap_server_register_methods() function of eap_methods.c. Each EAP
+method should use a build-time configuration option, e.g., EAP_TLS, in
+order to make it possible to select which of the methods are included
+in the build.
+
+EAP methods must implement the interface defined in eap_i.h. struct
+eap_method defines the needed function pointers that each EAP method
+must provide. In addition, the EAP type and name are registered using
+this structure. This interface is based on section 4.4 of RFC 4137.
+
+It is recommended that the EAP methods would use generic helper
+functions, eap_msg_alloc() and eap_hdr_validate() when processing
+messages. This allows code sharing and can avoid missing some of the
+needed validation steps for received packets. In addition, these
+functions make it easier to change between expanded and legacy EAP
+header, if needed.
+
+When adding an EAP method that uses a vendor specific EAP type
+(Expanded Type as defined in RFC 3748, Chapter 5.7), the new method
+must be registered by passing vendor id instead of EAP_VENDOR_IETF to
+eap_server_method_alloc(). These methods must not try to emulate
+expanded types by registering a legacy EAP method for type 254. See
+eap_vendor_test.c for an example of an EAP method implementation that
+is implemented as an expanded type.

+/**
+\mainpage Developers' documentation for hostapd
+
+hostapd includes IEEE 802.11 access point management (authentication /
+association), IEEE 802.1X/WPA/WPA2 Authenticator, EAP server, and
+RADIUS authentication server functionality. It can be build with
+various configuration option, e.g., a standalone AP management
+solution or a RADIUS authentication server with support for number of
+EAP methods.
+
+The goal of this documentation and comments in the source code is to
+give enough information for other developers to understand how hostapd
+has been implemented, how it can be modified, how new drivers can be
+supported, and how hostapd can be ported to other operating
+systems. If any information is missing, feel free to contact Jouni
+Malinen <j@w1.fi> for more information. Contributions as
+patch files are also very welcome at the same address. Please note
+that hostapd is licensed under dual license, GPLv2 or BSD at user's
+choice. All contributions to hostapd are expected to use compatible
+licensing terms.
+
+The source code and read-only access to hostapd CVS repository
+is available from the project home page at
+http://hostap.epitest.fi/hostapd/. This developers' documentation
+is also available as a PDF file from
+http://hostap.epitest.fi/hostapd/hostapd-devel.pdf .
+
+The design goal for hostapd was to use hardware, driver, and
+OS independent, portable C code for all WPA functionality. The source
+code is divided into separate C files as shown on the \ref
+code_structure "code structure page". All hardware/driver specific
+functionality is in separate files that implement a \ref
+driver_wrapper "well-defined driver API". Information about porting
+to different target boards and operating systems is available on
+the \ref porting "porting page".
+
+EAPOL (IEEE 802.1X) state machines are implemented as a separate
+module that interacts with \ref eap_module "EAP server implementation".
+Similarly, RADIUS authentication server is in its own separate module.
+Both IEEE 802.1X and RADIUS authentication server can use EAP server
+functionality.
+
+hostapd implements a \ref ctrl_iface_page "control interface" that can
+be used by external programs to control the operations of the hostapdt
+daemon and to get status information and event notifications. There is
+a small C library that provides helper functions to facilitate the use
+of the control interface. This library can also be used with C++.

+.SH NAME
+hostapd \- IEEE 802.11 AP, IEEE 802.1X/WPA/WPA2/EAP/RADIUS Authenticator
+.SH SYNOPSIS
+.B hostapd
+[-hdBKtv] [-P <PID file>] <configuration file(s)>
+.SH DESCRIPTION
+This manual page documents briefly the
+.B hostapd
+daemon.
+.PP
+.B hostapd
+is a user space daemon for access point and authentication servers.
+It implements IEEE 802.11 access point management, IEEE 802.1X/WPA/WPA2/EAP Authenticators and RADIUS authentication server.
+The current version supports Linux (Host AP, madwifi, Prism54 drivers) and FreeBSD (net80211).
+
+.B hostapd
+is designed to be a "daemon" program that runs in the background and acts as the backend component controlling authentication.
+.B hostapd
+supports separate frontend programs and an example text-based frontend,
+.BR hostapd_cli ,
+is included with
+.BR hostapd .
+.SH OPTIONS
+A summary of options is included below.
+For a complete description, run
+.BR hostapd
+from the command line.

+# - results in a valid MASK that covers it and the dev_addr
+# - is not the same as the MAC address of the radio
+# - is not the same as any other explicitly specified BSSID

+# hostapd user database for integrated EAP server
+
+# Each line must contain an identity, EAP method(s), and an optional password
+# separated with whitespace (space or tab). The identity and password must be
+# double quoted ("user"). Password can alternatively be stored as
+# NtPasswordHash (16-byte MD4 hash of the unicode presentation of the password
+# in unicode) if it is used for MSCHAP or MSCHAPv2 authentication. This means
+# that the plaintext password does not need to be included in the user file.
+# Password hash is stored as hash:<16-octets of hex data> without quotation
+# marks.
+
+# [2] flag in the end of the line can be used to mark users for tunneled phase
+# 2 authentication (e.g., within EAP-PEAP). In these cases, an anonymous
+# identity can be used in the unencrypted phase 1 and the real user identity
+# is transmitted only within the encrypted tunnel in phase 2. If non-anonymous
+# access is needed, two user entries is needed, one for phase 1 and another
+# with the same username for phase 2.
+#
+# EAP-TLS, EAP-PEAP, EAP-TTLS, EAP-FAST, EAP-SIM, and EAP-AKA do not use
+# password option.
+# EAP-MD5, EAP-MSCHAPV2, EAP-GTC, EAP-PAX, EAP-PSK, and EAP-SAKE require a
+# password.
+# EAP-PEAP, EAP-TTLS, and EAP-FAST require Phase 2 configuration.
+#
+# * can be used as a wildcard to match any user identity. The main purposes for
+# this are to set anonymous phase 1 identity for EAP-PEAP and EAP-TTLS and to
+# avoid having to configure every certificate for EAP-TLS authentication. The
+# first matching entry is selected, so * should be used as the last phase 1
+# user entry.
+#
+# "prefix"* can be used to match the given prefix and anything after this. The
+# main purpose for this is to be able to avoid EAP method negotiation when the
+# method is using known prefix in identities (e.g., EAP-SIM and EAP-AKA). This
+# is only allowed for phase 1 identities.
+#
+# Multiple methods can be configured to make the authenticator try them one by
+# one until the peer accepts one. The method names are separated with a
+# comma (,).
+#
+# [ver=0] and [ver=1] flags after EAP type PEAP can be used to force PEAP
+# version based on the Phase 1 identity. Without this flag, the EAP
+# authenticator advertises the highest supported version and select the version
+# based on the first PEAP packet from the supplicant.
+#
+# EAP-TTLS supports both EAP and non-EAP authentication inside the tunnel.
+# Tunneled EAP methods are configured with standard EAP method name and [2]
+# flag. Non-EAP methods can be enabled by following method names: TTLS-PAP,
+# TTLS-CHAP, TTLS-MSCHAP, TTLS-MSCHAPV2. TTLS-PAP and TTLS-CHAP require a
+# plaintext password while TTLS-MSCHAP and TTLS-MSCHAPV2 can use NT password

+SHA-1 in C
+By Steve Reid <sreid@sea-to-sky.net>
+100% Public Domain
+
+-----------------
+Modified 7/98 
+By James H. Brown <jbrown@burgoyne.com>
+Still 100% Public Domain
+
+Corrected a problem which generated improper hash values on 16 bit machines
+Routine SHA1Update changed from
+	void SHA1Update(SHA1_CTX* context, unsigned char* data, unsigned int
+len)
+to
+	void SHA1Update(SHA1_CTX* context, unsigned char* data, unsigned
+long len)
+
+The 'len' parameter was declared an int which works fine on 32 bit machines.
+However, on 16 bit machines an int is too small for the shifts being done
+against
+it.  This caused the hash function to generate incorrect values if len was
+greater than 8191 (8K - 1) due to the 'len << 3' on line 3 of SHA1Update().
+
+Since the file IO in main() reads 16K at a time, any file 8K or larger would
+be guaranteed to generate the wrong hash (e.g. Test Vector #3, a million
+"a"s).
+
+I also changed the declaration of variables i & j in SHA1Update to 
+unsigned long from unsigned int for the same reason.
+
+These changes should make no difference to any 32 bit implementations since
+an
+int and a long are the same size in those environments.
+
+--
+I also corrected a few compiler warnings generated by Borland C.
+1. Added #include <process.h> for exit() prototype
+2. Removed unused variable 'j' in SHA1Final
+3. Changed exit(0) to return(0) at end of main.
+
+ALL changes I made can be located by searching for comments containing 'JHB'

+ * See README and COPYING for more details.
+ *
+ * This is an example implementation of the EAP-SIM/AKA database/authentication
+ * gateway interface to HLR/AuC. It is expected to be replaced with an
+ * implementation of SS7 gateway to GSM/UMTS authentication center (HLR/AuC) or
+ * a local implementation of SIM triplet and AKA authentication data generator.
+ *
+ * hostapd will send SIM/AKA authentication queries over a UNIX domain socket
+ * to and external program, e.g., this hlr_auc_gw. This interface uses simple
+ * text-based format:
+ *
+ * EAP-SIM / GSM triplet query/response:
+ * SIM-REQ-AUTH <IMSI> <max_chal>
+ * SIM-RESP-AUTH <IMSI> Kc1:SRES1:RAND1 Kc2:SRES2:RAND2 [Kc3:SRES3:RAND3]
+ * SIM-RESP-AUTH <IMSI> FAILURE
+ *
+ * EAP-AKA / UMTS query/response:
+ * AKA-REQ-AUTH <IMSI>
+ * AKA-RESP-AUTH <IMSI> <RAND> <AUTN> <IK> <CK> <RES>
+ * AKA-RESP-AUTH <IMSI> FAILURE
+ *
+ * EAP-AKA / UMTS AUTS (re-synchronization):
+ * AKA-AUTS <IMSI> <AUTS> <RAND>
+ *
+ * IMSI and max_chal are sent as an ASCII string,
+ * Kc/SRES/RAND/AUTN/IK/CK/RES/AUTS as hex strings.
+ *
+ * The example implementation here reads GSM authentication triplets from a
+ * text file in IMSI:Kc:SRES:RAND format, IMSI in ASCII, other fields as hex
+ * strings. This is used to simulate an HLR/AuC. As such, it is not very useful
+ * for real life authentication, but it is useful both as an example
+ * implementation and for EAP-SIM testing.

+ * only small files are to be read. A maximum file size is provided by
+ * application and enforced.
+ *
+ * It is assumed that the application does not expect any of the following:
+ * -- transfer encoding other than chunked
+ * -- trailer fields
+ * It is assumed that, even if the other side requested that the connection be
+ * kept open, that we will close it (thus HTTP messages sent by application
+ * should have the connection closed field); this is allowed by HTTP/1.1 and
+ * simplifies things for us.
+ *
+ * Other limitations:
+ * -- HTTP header may not exceed a hard-coded size.
+ *
+ * Notes:
+ * This code would be massively simpler without some of the new features of
+ * HTTP/1.1, especially chunked data.

+ * This has been greatly stripped down from the original file
+ * (upnp_wps_device.c) by Ted Merrill, Atheros Communications
+ * in order to eliminate use of the bulky libupnp library etc.
+ *
+ * History:
+ * upnp_wps_device.c is/was a shim layer between wps_opt_upnp.c and
+ * the libupnp library.
+ * The layering (by Sony) was well done; only a very minor modification
+ * to API of upnp_wps_device.c was required.
+ * libupnp was found to be undesirable because:
+ * -- It consumed too much code and data space
+ * -- It uses multiple threads, making debugging more difficult
+ *      and possibly reducing reliability.
+ * -- It uses static variables and only supports one instance.
+ * The shim and libupnp are here replaced by special code written
+ * specifically for the needs of hostapd.
+ * Various shortcuts can and are taken to keep the code size small.
+ * Generally, execution time is not as crucial.
+ *
+ * BUGS:
+ * -- UPnP requires that we be able to resolve domain names.
+ * While uncommon, if we have to do it then it will stall the entire
+ * hostapd program, which is bad.
+ * This is because we use the standard linux getaddrinfo() function
+ * which is syncronous.
+ * An asyncronous solution would be to use the free "ares" library.
+ * -- Does not have a robust output buffering scheme.  Uses a single
+ * fixed size output buffer per TCP/HTTP connection, with possible (although
+ * unlikely) possibility of overflow and likely excessive use of RAM.
+ * A better solution would be to write the HTTP output as a buffered stream,
+ * using chunking: (handle header specially, then) generate data with
+ * a printf-like function into a buffer, catching buffer full condition,
+ * then send it out surrounded by http chunking.
+ * -- There is some code that could be separated out into the common
+ * library to be shared with wpa_supplicant.
+ * -- Needs renaming with module prefix to avoid polluting the debugger
+ * namespace and causing possible collisions with other static fncs
+ * and structure declarations when using the debugger.
+ * -- Just what should be in the first event message sent after subscription
+ * for the WLANEvent field? If i pass it empty, Vista replies with OK
+ * but apparently barfs on the message.
+ * -- The http error code generation is pretty bogus, hopefully noone cares.

+/*
+ * Overview of WPS over UPnP:
+ *
+ * UPnP is a protocol that allows devices to discover each other and control
+ * each other. In UPnP terminology, a device is either a "device" (a server
+ * that provides information about itself and allows itself to be controlled)
+ * or a "control point" (a client that controls "devices") or possibly both.
+ * This file implements a UPnP "device".
+ *
+ * For us, we use mostly basic UPnP discovery, but the control part of interest
+ * is WPS carried via UPnP messages. There is quite a bit of basic UPnP
+ * discovery to do before we can get to WPS, however.
+ *
+ * UPnP discovery begins with "devices" send out multicast UDP packets to a
+ * certain fixed multicast IP address and port, and "control points" sending
+ * out other such UDP packets.
+ *
+ * The packets sent by devices are NOTIFY packets (not to be confused with TCP
+ * NOTIFY packets that are used later) and those sent by control points are
+ * M-SEARCH packets. These packets contain a simple HTTP style header. The
+ * packets are sent redundantly to get around packet loss. Devices respond to
+ * M-SEARCH packets with HTTP-like UDP packets containing HTTP/1.1 200 OK
+ * messages, which give similar information as the UDP NOTIFY packets.
+ *
+ * The above UDP packets advertise the (arbitrary) TCP ports that the
+ * respective parties will listen to. The control point can then do a HTTP
+ * SUBSCRIBE (something like an HTTP PUT) after which the device can do a
+ * separate HTTP NOTIFY (also like an HTTP PUT) to do event messaging.
+ *
+ * The control point will also do HTTP GET of the "device file" listed in the
+ * original UDP information from the device (see UPNP_WPS_DEVICE_XML_FILE
+ * data), and based on this will do additional GETs... HTTP POSTs are done to
+ * cause an action.
+ *
+ * Beyond some basic information in HTTP headers, additional information is in
+ * the HTTP bodies, in a format set by the SOAP and XML standards, a markup
+ * language related to HTML used for web pages. This language is intended to
+ * provide the ultimate in self-documentation by providing a universal
+ * namespace based on pseudo-URLs called URIs. Note that although a URI looks
+ * like a URL (a web address), they are never accessed as such but are used
+ * only as identifiers.
+ *
+ * The POST of a GetDeviceInfo gets information similar to what might be
+ * obtained from a probe request or response on Wi-Fi. WPS messages M1-M8
+ * are passed via a POST of a PutMessage; the M1-M8 WPS messages are converted
+ * to a bin64 ascii representation for encapsulation. When proxying messages,
+ * WLANEvent and PutWLANResponse are used.
+ *
+ * This of course glosses over a lot of details.

+ *
+ * The base syntax of XML uses a few ASCII punctionation characters; any
+ * characters that would appear in the payload data are rewritten using
+ * sequences, e.g., &amp; for ampersand(&) and &lt for left angle bracket (<).
+ * Five such escapes total (more can be defined but that does not apply to our
+ * case). Thus we can safely parse for angle brackets etc.
+ *
+ * XML describes tree structures of tagged data, with each element beginning
+ * with an opening tag <label> and ending with a closing tag </label> with
+ * matching label. (There is also a self-closing tag <label/> which is supposed
+ * to be equivalent to <label></label>, i.e., no payload, but we are unlikely
+ * to see it for our purpose).
+ *
+ * Actually the opening tags are a little more complicated because they can
+ * contain "attributes" after the label (delimited by ascii space or tab chars)
+ * of the form attribute_label="value" or attribute_label='value'; as it turns
+ * out we do not have to read any of these attributes, just ignore them.
+ *
+ * Labels are any sequence of chars other than space, tab, right angle bracket
+ * (and ?), but may have an inner structure of <namespace><colon><plain_label>.
+ * As it turns out, we can ignore the namespaces, in fact we can ignore the
+ * entire tree hierarchy, because the plain labels we are looking for will be
+ * unique (not in general, but for this application). We do however have to be
+ * careful to skip over the namespaces.
+ *
+ * In generating XML we have to be more careful, but that is easy because
+ * everything we do is pretty canned. The only real care to take is to escape
+ * any special chars in our payload.

+ChangeLog for wpa_supplicant
+
+2009-02-15 - v0.6.8
+	* increased wpa_cli ping interval to 5 seconds and made this
+	  configurable with a new command line options (-G<seconds>)
+	* fixed scan buffer processing with WEXT to handle up to 65535
+	  byte result buffer (previously, limited to 32768 bytes)
+
+2009-01-06 - v0.6.7
+	* added support for Wi-Fi Protected Setup (WPS)
+	  (wpa_supplicant can now be configured to act as a WPS Enrollee to
+	  enroll credentials for a network using PIN and PBC methods; in
+	  addition, wpa_supplicant can act as a wireless WPS Registrar to
+	  configure an AP); WPS support can be enabled by adding CONFIG_WPS=y
+	  into .config and setting the runtime configuration variables in
+	  wpa_supplicant.conf (see WPS section in the example configuration
+	  file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to
+	  manage WPS negotiation; see README-WPS for more details
+	* added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
+	* added support for using driver_test over UDP socket
+	* fixed PEAPv0 Cryptobinding interoperability issue with Windows Server
+	  2008 NPS; optional cryptobinding is now enabled (again) by default
+	* fixed PSK editing in wpa_gui
+	* changed EAP-GPSK to use the IANA assigned EAP method type 51
+	* added a Windows installer that includes WinPcap and all the needed
+	  DLLs; in addition, it set up the registry automatically so that user
+	  will only need start wpa_gui to get prompted to start the wpasvc
+	  servide and add a new interface if needed through wpa_gui dialog
+	* updated management frame protection to use IEEE 802.11w/D7.0
+
+2008-11-23 - v0.6.6
+	* added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
+	  (can be used to simulate test SIM/USIM card with a known private key;
+	  enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
+	  and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
+	* added a new network configuration option, wpa_ptk_rekey, that can be
+	  used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
+	  against TKIP deficiencies
+	* added an optional mitigation mechanism for certain attacks against
+	  TKIP by delaying Michael MIC error reports by a random amount of time
+	  between 0 and 60 seconds; this can be enabled with a build option
+	  CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
+	* fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
+	  not bytes
+	* updated OpenSSL code for EAP-FAST to use an updated version of the
+	  session ticket overriding API that was included into the upstream
+	  OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
+	  needed with that version anymore)
+	* updated userspace MLME instructions to match with the current Linux
+	  mac80211 implementation; please also note that this can only be used
+	  with driver_nl80211.c (the old code from driver_wext.c was removed)
+	* added support (Linux only) for RoboSwitch chipsets (often found in
+	  consumer grade routers); driver interface 'roboswitch'
+	* fixed canceling of PMKSA caching when using drivers that generate
+	  RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
+	  about
+
+2008-11-01 - v0.6.5
+	* added support for SHA-256 as X.509 certificate digest when using the
+	  internal X.509/TLSv1 implementation
+	* updated management frame protection to use IEEE 802.11w/D6.0
+	* added support for using SHA256-based stronger key derivation for WPA2
+	  (IEEE 802.11w)
+	* fixed FT (IEEE 802.11r) authentication after a failed association to
+	  use correct FTIE
+	* added support for configuring Phase 2 (inner/tunneled) authentication
+	  method with wpa_gui-qt4
+
+2008-08-10 - v0.6.4
+	* added support for EAP Sequences in EAP-FAST Phase 2
+	* added support for using TNC with EAP-FAST
+	* added driver_ps3 for the PS3 Linux wireless driver
+	* added support for optional cryptobinding with PEAPv0
+	* fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
+	  allow fallback to full handshake if server rejects PAC-Opaque
+	* added fragmentation support for EAP-TNC
+	* added support for parsing PKCS #8 formatted private keys into the
+	  internal TLS implementation (both PKCS #1 RSA key and PKCS #8
+	  encapsulated RSA key can now be used)
+	* added option of using faster, but larger, routines in the internal
+	  LibTomMath (for internal TLS implementation) to speed up DH and RSA
+	  calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
+	* fixed race condition between disassociation event and group key
+	  handshake to avoid getting stuck in incorrect state [Bug 261]
+	* fixed opportunistic key caching (proactive_key_caching)
+
+2008-02-22 - v0.6.3
+	* removed 'nai' and 'eappsk' network configuration variables that were
+	  previously used for configuring user identity and key for EAP-PSK,
+	  EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
+	  replacement for 'nai' (if old configuration used a separate
+	  'identity' value, that would now be configured as
+	  'anonymous_identity'). 'password' field is now used as the
+	  replacement for 'eappsk' (it can also be set using hexstring to
+	  present random binary data)
+	* removed '-w' command line parameter (wait for interface to be added,
+	  if needed); cleaner way of handling this functionality is to use an
+	  external mechanism (e.g., hotplug scripts) that start wpa_supplicant
+	  when an interface is added
+	* updated FT support to use the latest draft, IEEE 802.11r/D9.0
+	* added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
+	  indicating when new scan results become available
+	* added new ctrl_iface command, BSS, to allow scan results to be
+	  fetched without hitting the message size limits (this command
+	  can be used to iterate through the scan results one BSS at the time)
+	* fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
+	  attributes in EAP-SIM Start/Response when using fast reauthentication
+	* fixed EAPOL not to end up in infinite loop when processing dynamic
+	  WEP keys with IEEE 802.1X
+	* fixed problems in getting NDIS events from WMI on Windows 2000
+
+2008-01-01 - v0.6.2
+	* added support for Makefile builds to include debug-log-to-a-file
+	  functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
+	* fixed EAP-SIM and EAP-AKA message parser to validate attribute
+	  lengths properly to avoid potential crash caused by invalid messages
+	* added data structure for storing allocated buffers (struct wpabuf);
+	  this does not affect wpa_supplicant usage, but many of the APIs
+	  changed and various interfaces (e.g., EAP) is not compatible with old
+	  versions
+	* added support for protecting EAP-AKA/Identity messages with
+	  AT_CHECKCODE (optional feature in RFC 4187)
+	* added support for protected result indication with AT_RESULT_IND for
+	  EAP-SIM and EAP-AKA (phase1="result_ind=1")
+	* added driver_wext workaround for race condition between scanning and
+	  association with drivers that take very long time to scan all
+	  channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
+	  using a longer hardcoded timeout for the scan if the driver supports
+	  notifications for scan completion (SIOCGIWSCAN event); this helps,
+	  e.g., in cases where wpa_supplicant and madwifi driver ended up in
+	  loop where the driver did not even try to associate
+	* stop EAPOL timer tick when no timers are in use in order to reduce
+	  power consumption (no need to wake up the process once per second)
+	  [Bug 237]
+	* added support for privilege separation (run only minimal part of
+	  wpa_supplicant functionality as root and rest as unprivileged,
+	  non-root process); see 'Privilege separation' in README for details;
+	  this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
+	  in .config
+	* changed scan results data structure to include all information
+	  elements to make it easier to support new IEs; old get_scan_result()
+	  driver_ops is still supported for backwards compatibility (results
+	  are converted internally to the new format), but all drivers should
+	  start using the new get_scan_results2() to make them more likely to
+	  work with new features
+	* Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
+	  application, i.e., it does not require Qt3Support anymore; Windows
+	  binary of wpa_gui.exe is now from this directory and only requires
+	  QtCore4.dll and QtGui4.dll libraries
+	* updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
+	  available as a separate package to make wpa_gui installation easier:
+	  http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
+	* added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
+	  only shared key/password authentication is supported in this version
+
+2007-11-24 - v0.6.1
+	* added support for configuring password as NtPasswordHash
+	  (16-byte MD4 hash of password) in hash:<32 hex digits> format
+	* added support for fallback from abbreviated TLS handshake to
+	  full handshake when using EAP-FAST (e.g., due to an expired
+	  PAC-Opaque)
+	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
+	  draft (draft-ietf-emu-eap-gpsk-07.txt)
+	* added support for drivers that take care of RSN 4-way handshake
+	  internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
+	  WPA_ALG_PMK in set_key)
+	* added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
+	  .config); this version supports only ap_scan=2 mode and allow the
+	  driver to take care of the 4-way handshake
+	* fixed a buffer overflow in parsing TSF from scan results when using
+	  driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
+	  [Bug 232]
+	* updated FT support to use the latest draft, IEEE 802.11r/D8.0
+	* fixed an integer overflow issue in the ASN.1 parser used by the
+	  (experimental) internal TLS implementation to avoid a potential
+	  buffer read overflow
+	* fixed a race condition with -W option (wait for a control interface
+	  monitor before starting) that could have caused the first messages to
+	  be lost
+	* added support for processing TNCC-TNCS-Messages to report
+	  recommendation (allow/none/isolate) when using TNC [Bug 243]
+
+2007-05-28 - v0.6.0
+	* added network configuration parameter 'frequency' for setting
+	  initial channel for IBSS (adhoc) networks
+	* added experimental IEEE 802.11r/D6.0 support
+	* updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
+	* updated EAP-PSK to use the IANA-allocated EAP type 47
+	* fixed EAP-PAX key derivation
+	* fixed EAP-PSK bit ordering of the Flags field
+	* fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
+	  tunnelled identity request (previously, the identifier from the outer
+	  method was used, not the tunnelled identifier which could be
+	  different)
+	* added support for fragmentation of outer TLS packets during Phase 2
+	  of EAP-PEAP/TTLS/FAST
+	* fixed EAP-TTLS AVP parser processing for too short AVP lengths
+	* added support for EAP-FAST authentication with inner methods that
+	  generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
+	  for PAC provisioning)
+	* added support for authenticated EAP-FAST provisioning
+	* added support for configuring maximum number of EAP-FAST PACs to
+	  store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
+	* added support for storing EAP-FAST PACs in binary format
+	  (fast_pac_format=binary in phase1 string)
+	* fixed dbus ctrl_iface to validate message interface before
+	  dispatching to avoid a possible segfault [Bug 190]
+	* fixed PeerKey key derivation to use the correct PRF label
+	* updated Windows binary build to link against OpenSSL 0.9.8d and
+	  added support for EAP-FAST
+	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
+	  draft (draft-ietf-emu-eap-gpsk-04.txt)
+	* fixed EAP-AKA Notification processing to allow Notification to be
+	  processed after AKA Challenge response has been sent
+	* updated to use IEEE 802.11w/D2.0 for management frame protection
+	  (still experimental)
+	* fixed EAP-TTLS implementation not to crash on use of freed memory
+	  if TLS library initialization fails
+	* added support for EAP-TNC (Trusted Network Connect)
+	  (this version implements the EAP-TNC method and EAP-TTLS changes
+	  needed to run two methods in sequence (IF-T) and the IF-IMC and
+	  IF-TNCCS interfaces from TNCC)
+
+2006-11-24 - v0.5.6
+	* added experimental, integrated TLSv1 client implementation with the
+	  needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
+	  setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
+	  .config); this can be useful, e.g., if the target system does not
+	  have a suitable TLS library and a minimal code size is required
+	  (total size of this internal TLS/crypto code is bit under 50 kB on
+	  x86 and the crypto code is shared by rest of the supplicant so some
+	  of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
+	* removed STAKey handshake since PeerKey handshake has replaced it in
+	  IEEE 802.11ma and there are no known deployments of STAKey
+	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
+	  draft (draft-ietf-emu-eap-gpsk-01.txt)
+	* added preliminary implementation of IEEE 802.11w/D1.0 (management
+	  frame protection)
+	  (Note: this requires driver support to work properly.)
+	  (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
+	* fixed Windows named pipes ctrl_iface to not stop listening for
+	  commands if client program opens a named pipe and closes it
+	  immediately without sending a command
+	* fixed USIM PIN status determination for the case that PIN is not
+	  needed (this allows EAP-AKA to be used with USIM cards that do not
+	  use PIN)
+	* added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
+	  be used with cards that do not support file selection based on
+	  partial AID
+	* added support for matching the subjectAltName of the authentication
+	  server certificate against multiple name components (e.g.,
+	  altsubject_match="DNS:server.example.com;DNS:server2.example.com")
+	* fixed EAP-SIM/AKA key derivation for re-authentication case (only
+	  affects IEEE 802.1X with dynamic WEP keys)
+	* changed ctrl_iface network configuration 'get' operations to not
+	  return password/key material; if these fields are requested, "*"
+	  will be returned if the password/key is set, but the value of the
+	  parameter is not exposed
+
+2006-08-27 - v0.5.5
+	* added support for building Windows version with UNICODE defined
+	  (wide-char functions)
+	* driver_ndis: fixed static WEP configuration to avoid race condition
+	  issues with some NDIS drivers between association and setting WEP
+	  keys
+	* driver_ndis: added validation for IELength value in scan results to
+	  avoid crashes when using buggy NDIS drivers [Bug 165]
+	* fixed Release|Win32 target in the Visual Studio project files
+	  (previously, only Debug|Win32 target was set properly)
+	* changed control interface API call wpa_ctrl_pending() to allow it to
+	  return -1 on error (e.g., connection lost); control interface clients
+	  will need to make sure that they verify that the value is indeed >0
+	  when determining whether there are pending messages
+	* added an alternative control interface backend for Windows targets:
+	  Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
+	  control interface mechanism for Windows builds (previously, UDP to
+	  localhost was used)
+	* changed ctrl_interface configuration for UNIX domain sockets:
+	  - deprecated ctrl_interface_group variable (it may be removed in
+	    future versions)
+	  - allow both directory and group be configured with ctrl_interface
+	    in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
+	  - ctrl_interface=/var/run/wpa_supplicant is still supported for the
+	    case when group is not changed
+	* added support for controlling more than one interface per process in
+	  Windows version
+	* added a workaround for a case where the AP is using unknown address
+	  (e.g., MAC address of the wired interface) as the source address for
+	  EAPOL-Key frames; previously, that source address was used as the
+	  destination for EAPOL-Key frames and in key derivation; now, BSSID is
+	  used even if the source address does not match with it
+	  (this resolves an interoperability issue with Thomson SpeedTouch 580)
+	* added a workaround for UDP-based control interface (which was used in
+	  Windows builds before this release) to prevent packets with forged
+	  addresses from being accepted as local control requests
+	* removed ndis_events.cpp and possibility of using external
+	  ndis_events.exe; C version (ndis_events.c) is fully functional and
+	  there is no desire to maintain two separate versions of this
+	  implementation
+	* ndis_events: Changed NDIS event notification design to use WMI to
+	  learn the adapter description through Win32_PnPEntity class; this
+	  should fix some cases where the adapter name was not recognized
+	  correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
+	  USB) [Bug 113]
+	* fixed selection of the first network in ap_scan=2 mode; previously,
+	  wpa_supplicant could get stuck in SCANNING state when only the first
+	  network for enabled (e.g., after 'wpa_cli select_network 0')
+	* winsvc: added support for configuring ctrl_interface parameters in
+	  registry (ctrl_interface string value in
+	  HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
+	  required to enable control interface (previously, this was hardcoded
+	  to be enabled)
+	* allow wpa_gui subdirectory to be built with both Qt3 and Qt4
+	* converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
+
+2006-06-20 - v0.5.4
+	* fixed build with CONFIG_STAKEY=y [Bug 143]
+	* added support for doing MLME (IEEE 802.11 management frame
+	  processing) in wpa_supplicant when using Devicescape IEEE 802.11
+	  stack (wireless-dev.git tree)
+	* added a new network block configuration option, fragment_size, to
+	  configure the maximum EAP fragment size
+	* driver_ndis: Disable WZC automatically for the selected interface to
+	  avoid conflicts with two programs trying to control the radio; WZC
+	  will be re-enabled (if it was enabled originally) when wpa_supplicant
+	  is terminated
+	* added an experimental TLSv1 client implementation
+	  (CONFIG_TLS=internal) that can be used instead of an external TLS
+	  library, e.g., to reduce total size requirement on systems that do
+	  not include any TLS library by default (this is not yet complete;
+	  basic functionality is there, but certificate validation is not yet
+	  included)
+	* added PeerKey handshake implementation for IEEE 802.11e
+	  direct link setup (DLS) to replace STAKey handshake
+	* fixed WPA PSK update through ctrl_iface for the case where the old
+	  PSK was derived from an ASCII passphrase and the new PSK is set as
+	  a raw PSK (hex string)
+	* added new configuration option for identifying which network block
+	  was used (id_str in wpa_supplicant.conf; included on
+	  WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
+	  variable in wpa_cli action scripts; in addition WPA_ID variable is
+	  set to the current unique identifier that wpa_supplicant assigned
+	  automatically for the network and that can be used with
+	  GET_NETWORK/SET_NETWORK ctrl_iface commands)
+	* wpa_cli action script is now called only when the connect/disconnect
+	  status changes or when associating with a different network
+	* fixed configuration parser not to remove CCMP from group cipher list
+	  if WPA-None (adhoc) is used (pairwise=NONE in that case)
+	* fixed integrated NDIS events processing not to hang the process due
+	  to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
+	* added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
+	  draft-clancy-emu-eap-shared-secret-00.txt)
+	* added Microsoft Visual Studio 2005 solution and project files for
+	  build wpa_supplicant for Windows (see vs2005 subdirectory)
+	* eloop_win: fixed unregistration of Windows events
+	* l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
+	  at the end of RSN pre-authentication and added unregistration of
+	  a Windows event to avoid getting eloop_win stuck with an invalid
+	  handle
+	* driver_ndis: added support for selecting AP based on BSSID
+	* added new environmental variable for wpa_cli action scripts:
+	  WPA_CTRL_DIR is the current control interface directory
+	* driver_ndis: added support for using NDISUIO instead of WinPcap for
+	  OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
+	  l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
+	  wpa_supplicant without requiring WinPcap; note that using NDISUIO
+	  requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
+	  only one application to open the device
+	* changed NDIS driver naming to only include device GUID, e.g.,
+	  {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
+	  specific \Device\NPF_ prefix before the GUID; the prefix is still
+	  allowed for backwards compatibility, but it is not required anymore
+	  when specifying the interface
+	* driver_ndis: re-initialize driver interface is the adapter is removed
+	  and re-inserted [Bug 159]
+	* driver_madwifi: fixed TKIP and CCMP sequence number configuration on
+	  big endian hosts [Bug 146]
+
+2006-04-27 - v0.5.3
+	* fixed EAP-GTC response to include correct user identity when run as
+	  phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
+	* driver_ndis: Fixed encryption mode configuration for unencrypted
+	  networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
+	  refused to associate with open networks) [Bug 106]
+	* driver_ndis: use BSSID OID polling to detect when IBSS network is
+	  formed even when ndis_events code is included since some NDIS drivers
+	  do not generate media connect events in IBSS mode
+	* config_winreg: allow global ctrl_interface parameter to be configured
+	  in Windows registry
+	* config_winreg: added support for saving configuration data into
+	  Windows registry
+	* added support for controlling network device operational state
+	  (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
+	  http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
+	  that can use this information)
+	* driver_wext: added support for WE-21 change to SSID configuration
+	* driver_wext: fixed privacy configuration for static WEP keys mode
+	  [Bug 140]
+	* added an optional driver_ops callback for MLME-SETPROTECTION.request
+	  primitive
+	* added support for EAP-SAKE (no EAP method number allocated yet, so
+	  this is using the same experimental type 255 as EAP-PSK)
+	* added support for dynamically loading EAP methods (.so files) instead
+	  of requiring them to be statically linked in; this is disabled by
+	  default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
+	  on how to use this)
+
+2006-03-19 - v0.5.2
+	* do not try to use USIM APDUs when initializing PC/SC for SIM card
+	  access for a network that has not enabled EAP-AKA
+	* fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
+	  v0.5.1 due to the new support for expanded EAP types)
+	* added support for generating EAP Expanded Nak
+	* try to fetch scan results once before requesting new scan when
+	  starting up in ap_scan=1 mode (this can speed up initial association
+	  a lot with, e.g., madwifi-ng driver)
+	* added support for receiving EAPOL frames from a Linux bridge
+	  interface (-bbr0 on command line)
+	* fixed EAPOL re-authentication for sessions that used PMKSA caching
+	* changed EAP method registration to use a dynamic list of methods
+	  instead of a static list generated at build time
+	* fixed PMKSA cache deinitialization not to use freed memory when
+	  removing PMKSA entries
+	* fixed a memory leak in EAP-TTLS re-authentication
+	* reject WPA/WPA2 message 3/4 if it does not include any valid
+	  WPA/RSN IE
+	* driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
+	  if the driver does not support SIOCSIWAUTH
+
+2006-01-29 - v0.5.1
+	* driver_test: added better support for multiple APs and STAs by using
+	  a directory with sockets that include MAC address for each device in
+	  the name (driver_param=test_dir=/tmp/test)
+	* added support for EAP expanded type (vendor specific EAP methods)
+	* added AP_SCAN command into ctrl_iface so that ap_scan configuration
+	  option can be changed if needed
+	* wpa_cli/wpa_gui: skip non-socket files in control directory when
+	  using UNIX domain sockets; this avoids selecting an incorrect
+	  interface (e.g., a PID file could be in this directory, even though
+	  use of this directory for something else than socket files is not
+	  recommended)
+	* fixed TLS library deinitialization after RSN pre-authentication not
+	  to disable TLS library for normal authentication
+	* driver_wext: Remove null-termination from SSID length if the driver
+	  used it; some Linux drivers do this and they were causing problems in
+	  wpa_supplicant not finding matching configuration block. This change
+	  would break a case where the SSID actually ends in '\0', but that is
+	  not likely to happen in real use.
+	* fixed PMKSA cache processing not to trigger deauthentication if the
+	  current PMKSA cache entry is replaced with a valid new entry
+	* fixed PC/SC initialization for ap_scan != 1 modes (this fixes
+	  EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
+	  ap_scan=2)
+
+2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
+	* added experimental STAKey handshake implementation for IEEE 802.11e
+	  direct link setup (DLS); note: this is disabled by default in both
+	  build and runtime configuration (can be enabled with CONFIG_STAKEY=y
+	  and stakey=1)
+	* fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
+	  decrypt AT_ENCR_DATA attributes correctly
+	* fixed EAP-AKA to allow resynchronization within the same session
+	* made code closer to ANSI C89 standard to make it easier to port to
+	  other C libraries and compilers
+	* started moving operating system or C library specific functions into
+	  wrapper functions defined in os.h and implemented in os_*.c to make
+	  code more portable
+	* wpa_supplicant can now be built with Microsoft Visual C++
+	  (e.g., with the freely available Toolkit 2003 version or Visual
+	  C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
+	  example makefile for nmake
+	* added support for using Windows registry for command line parameters
+	  (CONFIG_MAIN=main_winsvc) and configuration data
+	  (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
+	  contents; this version can be run both as a Windows service and as a
+	  normal application; 'wpasvc.exe app' to start as applicant,
+	  'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
+	  'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
+	  unregister a service
+	* made it possible to link ndis_events.exe functionality into
+	  wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
+	* added better support for multiple control interface backends
+	  (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
+	* fixed PC/SC code to use correct length for GSM AUTH command buffer
+	  and to not use pioRecvPci with SCardTransmit() calls; these were not
+	  causing visible problems with pcsc-lite, but Windows Winscard.dll
+	  refused the previously used parameters; this fixes EAP-SIM and
+	  EAP-AKA authentication using SIM/USIM card under Windows
+	* added new event loop implementation for Windows using
+	  WaitForMultipleObject() instead of select() in order to allow waiting
+	  for non-socket objects; this can be selected with
+	  CONFIG_ELOOP=eloop_win in .config
+	* added support for selecting l2_packet implementation in .config
+	  (CONFIG_L2_PACKET; following options are available now: linux, pcap,
+	  winpcap, freebsd, none)
+	* added new l2_packet implementation for WinPcap
+	  (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
+	  reduce latency in EAPOL receive processing from about 100 ms to about
+	  3 ms
+	* added support for EAP-FAST key derivation using other ciphers than
+	  RC4-128-SHA for authentication and AES128-SHA for provisioning
+	* added support for configuring CA certificate as DER file and as a
+	  configuration blob
+	* fixed private key configuration as configuration blob and added
+	  support for using PKCS#12 as a blob
+	* tls_gnutls: added support for using PKCS#12 files; added support for
+	  session resumption
+	* added support for loading trusted CA certificates from Windows
+	  certificate store: ca_cert="cert_store://<name>", where <name> is
+	  likely CA (Intermediate CA certificates) or ROOT (root certificates)
+	* added C version of ndis_events.cpp and made it possible to build this
+	  with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
+	  easily on cross-compilation builds
+	* added wpasvc.exe into Windows binary release; this is an alternative
+	  version of wpa_supplicant.exe with configuration backend using
+	  Windows registry and with the entry point designed to run as a
+	  Windows service
+	* integrated ndis_events.exe functionality into wpa_supplicant.exe and
+	  wpasvc.exe and removed this additional tool from the Windows binary
+	  release since it is not needed anymore
+	* load winscard.dll functions dynamically when building with MinGW
+	  since MinGW does not yet include winscard library
+
+2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
+	* l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
+	  and WinPcap to receive frames sent to PAE group address
+	* disable EAP state machine when IEEE 802.1X authentication is not used
+	  in order to get rid of bogus "EAP failed" messages
+	* fixed OpenSSL error reporting to go through all pending errors to
+	  avoid confusing reports of old errors being reported at later point
+	  during handshake
+	* fixed configuration file updating to not write empty variables
+	  (e.g., proto or key_mgmt) that the file parser would not accept
+	* fixed ADD_NETWORK ctrl_iface command to use the same default values
+	  for variables as empty network definitions read from config file
+	  would get
+	* fixed EAP state machine to not discard EAP-Failure messages in many
+	  cases (e.g., during TLS handshake)
+	* fixed a infinite loop in private key reading if the configured file
+	  cannot be parsed successfully
+	* driver_madwifi: added support for madwifi-ng
+	* wpa_gui: do not display password/PSK field contents
+	* wpa_gui: added CA certificate configuration
+	* driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
+	* driver_ndis: include Beacon IEs in AssocInfo in order to notice if
+	  the new AP is using different WPA/RSN IE
+	* use longer timeout for IEEE 802.11 association to avoid problems with
+	  drivers that may take more than five second to associate
+
+2005-10-27 - v0.4.6
+	* allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
+	  RSN IE, but WPA IE would match with wpa_supplicant configuration
+	* added support for named configuration blobs in order to avoid having
+	  to use file system for external files (e.g., certificates);
+	  variables can be set to "blob://<blob name>" instead of file path to
+	  use a named blob; supported fields: pac_file, client_cert,
+	  private_key
+	* fixed RSN pre-authentication (it was broken in the clean up of WPA
+	  state machine interface in v0.4.5)
+	* driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
+	  sure the driver configures broadcast decryption correctly
+	* added ca_path (and ca_path2) configuration variables that can be used
+	  to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
+	  system-wide trusted CA list
+	* added support for starting wpa_supplicant without a configuration
+	  file (-C argument must be used to set ctrl_interface parameter for
+	  this case; in addition, -p argument can be used to provide
+	  driver_param; these new arguments can also be used with a
+	  configuration to override the values from the configuration)
+	* added global control interface that can be optionally used for adding
+	  and removing network interfaces dynamically (-g command line argument
+	  for both wpa_supplicant and wpa_cli) without having to restart
+	  wpa_supplicant process
+	* wpa_gui:
+	  - try to save configuration whenever something is modified
+	  - added WEP key configuration
+	  - added possibility to edit the current network configuration
+	* driver_ndis: fixed driver polling not to increase frequency on each
+	  received EAPOL frame due to incorrectly cancelled timeout
+	* added simple configuration file examples (in examples subdirectory)
+	* fixed driver_wext.c to filter wireless events based on ifindex to
+	  avoid interfaces receiving events from other interfaces
+	* delay sending initial EAPOL-Start couple of seconds to speed up
+	  authentication for the most common case of Authenticator starting
+	  EAP authentication immediately after association
+
+2005-09-25 - v0.4.5
+	* added a workaround for clearing keys with ndiswrapper to allow
+	  roaming from WPA enabled AP to plaintext one
+	* added docbook documentation (doc/docbook) that can be used to
+	  generate, e.g., man pages
+	* l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
+	  PF_PACKET in order to prepare for network devices that do not use
+	  Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
+	* use receipt of EAPOL-Key frame as a lower layer success indication
+	  for EAP state machine to allow recovery from dropped EAP-Success
+	  frame
+	* cleaned up internal EAPOL frame processing by not including link
+	  layer (Ethernet) header during WPA and EAPOL/EAP processing; this
+	  header is added only when transmitted the frame; this makes it easier
+	  to use wpa_supplicant on link layers that use different header than
+	  Ethernet
+	* updated EAP-PSK to use draft 9 by default since this can now be
+	  tested with hostapd; removed support for draft 3, including
+	  server_nai configuration option from network blocks
+	* driver_wired: add PAE address to the multicast address list in order
+	  to be able to receive EAPOL frames with drivers that do not include
+	  these multicast addresses by default
+	* driver_wext: add support for WE-19
+	* added support for multiple configuration backends (CONFIG_BACKEND
+	  option); currently, only 'file' is supported (i.e., the format used
+	  in wpa_supplicant.conf)
+	* added support for updating configuration ('wpa_cli save_config');
+	  this is disabled by default and can be enabled with global
+	  update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
+	  and wpa_gui to store the configuration changes in a permanent store
+	* added GET_NETWORK ctrl_iface command
+	  (e.g., 'wpa_cli get_network 0 ssid')
+
+2005-08-21 - v0.4.4
+	* replaced OpenSSL patch for EAP-FAST support
+	  (openssl-tls-extensions.patch) with a more generic and correct
+	  patch (the new patch is not compatible with the previous one, so the
+	  OpenSSL library will need to be patched with the new patch in order
+	  to be able to build wpa_supplicant with EAP-FAST support)
+	* added support for using Windows certificate store (through CryptoAPI)
+	  for client certificate and private key operations (EAP-TLS)
+	  (see wpa_supplicant.conf for more information on how to configure
+	  this with private_key)
+	* ported wpa_gui to Windows
+	* added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
+	  built with the open source version of the Qt4 for Windows
+	* allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
+	  with drivers that do not support WPA
+	* ndis_events: fixed Windows 2000 support
+	* added support for enabling/disabling networks from the list of all
+	  configured networks ('wpa_cli enable_network <network id>' and
+	  'wpa_cli disable_network <network id>')
+	* added support for adding and removing network from the current
+	  configuration ('wpa_cli add_network' and 'wpa_cli remove_network
+	  <network id>'); added networks are disabled by default and they can
+	  be enabled with enable_network command once the configuration is done
+	  for the new network; note: configuration file is not yet updated, so
+	  these new networks are lost when wpa_supplicant is restarted
+	* added support for setting network configuration parameters through
+	  the control interface, for example:
+	  wpa_cli set_network 0 ssid "\"my network\""
+	* fixed parsing of strings that include both " and # within double
+	  quoted area (e.g., "start"#end")
+	* added EAP workaround for PEAP session resumption: allow outer,
+	  i.e., not tunneled, EAP-Success to terminate session since; this can
+	  be disabled with eap_workaround=0
+	  (this was allowed for PEAPv1 before, but now it is also allowed for
+	  PEAPv0 since at least one RADIUS authentication server seems to be
+	  doing this for PEAPv0, too)
+	* wpa_gui: added preliminary support for adding new networks to the
+	  wpa_supplicant configuration (double click on the scan results to
+	  open network configuration)
+
+2005-06-26 - v0.4.3
+	* removed interface for external EAPOL/EAP supplicant (e.g.,
+	  Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
+	  anymore and is unlikely to be used by anyone
+	* driver_ndis: fixed WinPcap 3.0 support
+	* fixed build with CONFIG_DNET_PCAP=y on Linux
+	* l2_packet: moved different implementations into separate files
+	  (l2_packet_*.c)
+
+2005-06-12 - v0.4.2
+	* driver_ipw: updated driver structures to match with ipw2200-1.0.4
+	  (note: ipw2100-1.1.0 is likely to require an update to work with
+	  this)
+	* added support for using ap_scan=2 mode with multiple network blocks;
+	  wpa_supplicant will go through the networks one by one until the
+	  driver reports a successful association; this uses the same order for
+	  networks as scan_ssid=1 scans, i.e., the priority field is ignored
+	  and the network block order in the file is used instead
+	* fixed a potential issue in RSN pre-authentication ending up using
+	  freed memory if pre-authentication times out
+	* added support for matching alternative subject name extensions of the
+	  authentication server certificate; new configuration variables
+	  altsubject_match and altsubject_match2
+	* driver_ndis: added support for IEEE 802.1X authentication with wired
+	  NDIS drivers
+	* added support for querying private key password (EAP-TLS) through the
+	  control interface (wpa_cli/wpa_gui) if one is not included in the
+	  configuration file
+	* driver_broadcom: fixed couple of memory leaks in scan result
+	  processing
+	* EAP-PAX is now registered as EAP type 46
+	* fixed EAP-PAX MAC calculation
+	* fixed EAP-PAX CK and ICK key derivation
+	* added support for using password with EAP-PAX (as an alternative to
+	  entering key with eappsk); SHA-1 hash of the password will be used as
+	  the key in this case
+	* added support for arbitrary driver interface parameters through the
+	  configuration file with a new driver_param field; this adds a new
+	  driver_ops function set_param()
+	* added possibility to override l2_packet module with driver interface
+	  API (new send_eapol handler); this can be used to implement driver
+	  specific TX/RX functions for EAPOL frames
+	* fixed ctrl_interface_group processing for the case where gid is
+	  entered as a number, not group name
+	* driver_test: added support for testing hostapd with wpa_supplicant
+	  by using test driver interface without any kernel drivers or network
+	  cards
+
+2005-05-22 - v0.4.1
+	* driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
+	  packets to be encrypted; this was apparently broken by the changed
+	  ioctl order in v0.4.0
+	* driver_madwifi: added preliminary support for compiling against 'BSD'
+	  branch of madwifi CVS tree
+	* added support for EAP-MSCHAPv2 password retries within the same EAP
+	  authentication session
+	* added support for password changes with EAP-MSCHAPv2 (used when the
+	  password has expired)
+	* added support for reading additional certificates from PKCS#12 files
+	  and adding them to the certificate chain
+	* fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
+	  were used
+	* fixed a possible double free in EAP-TTLS fast-reauthentication when
+	  identity or password is entered through control interface
+	* display EAP Notification messages to user through control interface
+	  with "CTRL-EVENT-EAP-NOTIFICATION" prefix
+	* added GUI version of wpa_cli, wpa_gui; this is not build
+	  automatically with 'make'; use 'make wpa_gui' to build (this requires
+	  Qt development tools)
+	* added 'disconnect' command to control interface for setting
+	  wpa_supplicant in state where it will not associate before
+	  'reassociate' command has been used
+	* added support for selecting a network from the list of all configured
+	  networks ('wpa_cli select_network <network id>'; this disabled all
+	  other networks; to re-enable, 'wpa_cli select_network any')
+	* added support for getting scan results through control interface
+	* added EAP workaround for PEAPv1 session resumption: allow outer,
+	  i.e., not tunneled, EAP-Success to terminate session since; this can
+	  be disabled with eap_workaround=0
+
+2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
+	* added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
+	  used to reduce the size of the wpa_supplicant considerably if
+	  debugging code is not needed
+	* fixed EAPOL-Key validation to drop packets with invalid Key Data
+	  Length; such frames could have crashed wpa_supplicant due to buffer
+	  overflow
+	* added support for wired authentication (IEEE 802.1X on wired
+	  Ethernet); driver interface 'wired'
+	* obsoleted set_wpa() handler in the driver interface API (it can be
+	  replaced by moving enable/disable functionality into init()/deinit())
+	  (calls to set_wpa() are still present for backwards compatibility,
+	  but they may be removed in the future)
+	* driver_madwifi: fixed association in plaintext mode
+	* modified the EAP workaround that accepts EAP-Success with incorrect
+	  Identifier to be even less strict about verification in order to
+	  interoperate with some authentication servers
+	* added support for sending TLS alerts
+	* added support for 'any' SSID wildcard; if ssid is not configured or
+	  is set to an empty string, any SSID will be accepted for non-WPA AP
+	* added support for asking PIN (for SIM) from frontends (e.g.,
+	  wpa_cli); if a PIN is needed, but not included in the configuration
+	  file, a control interface request is sent and EAP processing is
+	  delayed until the PIN is available
+	* added support for using external devices (e.g., a smartcard) for
+	  private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
+	  new wpa_supplicant.conf variables:
+	  - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
+	  - network: engine, engine_id, key_id
+	* added experimental support for EAP-PAX
+	* added monitor mode for wpa_cli (-a<path to a program to run>) that
+	  allows external commands (e.g., shell scripts) to be run based on
+	  wpa_supplicant events, e.g., when authentication has been completed
+	  and data connection is ready; other related wpa_cli arguments:
+	  -B (run in background), -P (write PID file); wpa_supplicant has a new
+	  command line argument (-W) that can be used to make it wait until a
+	  control interface command is received in order to avoid missing
+	  events
+	* added support for opportunistic WPA2 PMKSA key caching (disabled by
+	  default, can be enabled with proactive_key_caching=1)
+	* fixed RSN IE in 4-Way Handshake message 2/4 for the case where
+	  Authenticator rejects PMKSA caching attempt and the driver is not
+	  using assoc_info events
+	* added -P<pid file> argument for wpa_supplicant to write the current
+	  process id into a file
+
+2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
+	* added new phase1 option parameter, include_tls_length=1, to force
+	  wpa_supplicant to add TLS Message Length field to all TLS messages
+	  even if the packet is not fragmented; this may be needed with some
+	  authentication servers
+	* fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
+	  using drivers that take care of AP selection (e.g., when using
+	  ap_scan=2)
+	* fixed reprocessing of pending request after ctrl_iface requests for
+	  identity/password/otp
+	* fixed ctrl_iface requests for identity/password/otp in Phase 2 of
+	  EAP-PEAP and EAP-TTLS
+	* all drivers using driver_wext: set interface up and select Managed
+	  mode when starting wpa_supplicant; set interface down when exiting
+	* renamed driver_ipw2100.c to driver_ipw.c since it now supports both
+	  ipw2100 and ipw2200; please note that this also changed the
+	  configuration variable in .config to CONFIG_DRIVER_IPW
+
+2005-01-24 - v0.3.6
+	* fixed a busy loop introduced in v0.3.5 for scan result processing
+	  when no matching AP is found
+
+2005-01-23 - v0.3.5
+	* added a workaround for an interoperability issue with a Cisco AP
+	  when using WPA2-PSK
+	* fixed non-WPA IEEE 802.1X to use the same authentication timeout as
+	  WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
+	  retransmission of dropped frames)
+	* fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
+	  (e.g., segfault when processing EAPOL-Key frames)
+	* fixed EAP workaround and fast reauthentication configuration for
+	  RSN pre-authentication; previously these were disabled and
+	  pre-authentication would fail if the used authentication server
+	  requires EAP workarounds
+	* added support for blacklisting APs that fail or timeout
+	  authentication in ap_scan=1 mode so that all APs are tried in cases
+	  where the ones with strongest signal level are failing authentication
+	* fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
+	  authentication attempt
+	* allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
+	  in the previous authentication (previously, only Phase 1 success was
+	  verified)
+
+2005-01-09 - v0.3.4
+	* added preliminary support for IBSS (ad-hoc) mode configuration
+	  (mode=1 in network block); this included a new key_mgmt mode
+	  WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
+	  key management; see wpa_supplicant.conf for more details and an
+	  example on how to configure this (note: this is currently implemented
+	  only for driver_hostapd.c, but the changes should be trivial to add
+	  in associate() handler for other drivers, too (assuming the driver
+	  supports WPA-None)
+	* added preliminary port for native Windows (i.e., no cygwin) using
+	  mingw
+
+2005-01-02 - v0.3.3
+	* added optional support for GNU Readline and History Libraries for
+	  wpa_cli (CONFIG_READLINE)
+	* cleaned up EAP state machine <-> method interface and number of
+	  small problems with error case processing not terminating on
+	  EAP-Failure but waiting for timeout
+	* added couple of workarounds for interoperability issues with a
+	  Cisco AP when using WPA2
+	* added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
+	  Note: This requires a patch for openssl to add support for TLS
+	  extensions and number of workarounds for operations without
+	  certificates. Proof of concept type of experimental patch is
+	  included in openssl-tls-extensions.patch.
+
+2004-12-19 - v0.3.2
+	* fixed private key loading for cases where passphrase is not set
+	* fixed Windows/cygwin L2 packet handler freeing; previous version
+	  could cause a segfault when RSN pre-authentication was completed
+	* added support for PMKSA caching with drivers that generate RSN IEs
+	  (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
+	  but similar code can be easily added to driver_ndiswrapper.c once
+	  ndiswrapper gets full support for RSN PMKSA caching
+	* improved recovery from PMKID mismatches by requesting full EAP
+	  authentication in case of failed PMKSA caching attempt
+	* driver_ndis: added support for NDIS NdisMIncidateStatus() events
+	  (this requires that ndis_events is ran while wpa_supplicant is
+	  running)
+	* driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
+	* added support for driver interfaces to replace the interface name
+	  based on driver/OS specific mapping, e.g., in case of driver_ndis,
+	  this allows the beginning of the adapter description to be used as
+	  the interface name
+	* added support for CR+LF (Windows-style) line ends in configuration
+	  file
+	* driver_ndis: enable radio before starting scanning, disable radio
+	  when exiting
+	* modified association event handler to set portEnabled = FALSE before
+	  clearing port Valid in order to reset EAP state machine and avoid
+	  problems with new authentication getting ignored because of state
+	  machines ending up in AUTHENTICATED/SUCCESS state based on old
+	  information
+	* added support for driver events to add PMKID candidates in order to
+	  allow drivers to give priority to most likely roaming candidates
+	* driver_hostap: moved PrivacyInvoked configuration to associate()
+	  function so that this will not be set for plaintext connections
+	* added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
+	  interface can distinguish plaintext and IEEE 802.1X (no WPA)
+	  authentication
+	* fixed static WEP key configuration to use broadcast/default type for
+	  all keys (previously, the default TX key was configured as pairwise/
+	  unicast key)
+	* driver_ndis: added legacy WPA capability detection for non-WPA2
+	  drivers
+	* added support for setting static WEP keys for IEEE 802.1X without
+	  dynamic WEP keying (eapol_flags=0)
+
+2004-12-12 - v0.3.1
+	* added support for reading PKCS#12 (PFX) files (as a replacement for
+	  PEM/DER) to get certificate and private key (CONFIG_PKCS12)
+	* fixed compilation with CONFIG_PCSC=y
+	* added new ap_scan mode, ap_scan=2, for drivers that take care of
+	  association, but need to be configured with security policy and SSID,
+	  e.g., ndiswrapper and NDIS driver; this mode should allow such
+	  drivers to work with hidden SSIDs and optimized roaming; when
+	  ap_scan=2 is used, only the first network block in the configuration
+	  file is used and this configuration should have explicit security
+	  policy (i.e., only one option in the lists) for key_mgmt, pairwise,
+	  group, proto variables
+	* added experimental port of wpa_supplicant for Windows
+	  - driver_ndis.c driver interface (NDIS OIDs)
+	  - currently, this requires cygwin and WinPcap
+	  - small utility, win_if_list, can be used to get interface name
+	* control interface can now be removed at build time; add
+	  CONFIG_CTRL_IFACE=y to .config to maintain old functionality
+	* optional Xsupplicant interface can now be removed at build time;
+	  (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
+	* added auth_alg to driver interface associate() parameters to make it
+	  easier for drivers to configure authentication algorithm as part of
+	  the association
+
+2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
+	* driver_broadcom: added new driver interface for Broadcom wl.o driver
+	  (a generic driver for Broadcom IEEE 802.11a/g cards)
+	* wpa_cli: fixed parsing of -p <path> command line argument
+	* PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
+	  ACK, not tunneled EAP-Success (of which only the first byte was
+	  actually send due to a bug in previous code); this seems to
+	  interoperate with most RADIUS servers that implements PEAPv1
+	* PEAPv1: added support for terminating PEAP authentication on tunneled
+	  EAP-Success message; this can be configured by adding
+	  peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
+	  (some RADIUS servers require this whereas others require a tunneled
+	  reply
+	* PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
+	  the old label for key derivation; previously, the default was 1,
+	  but it looks like most existing PEAPv1 implementations use the old
+	  label which is thus more suitable default option
+	* added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
+	* fixed parsing of wep_tx_keyidx
+	* added support for configuring list of allowed Phase 2 EAP types
+	  (for both EAP-PEAP and EAP-TTLS) instead of only one type
+	* added support for configuring IEEE 802.11 authentication algorithm
+	  (auth_alg; mainly for using Shared Key authentication with static
+	  WEP keys)
+	* added support for EAP-AKA (with UMTS SIM)
+	* fixed couple of errors in PCSC handling that could have caused
+	  random-looking errors for EAP-SIM
+	* added support for EAP-SIM pseudonyms and fast re-authentication
+	* added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
+	  session resumption)
+	* added support for EAP-SIM with two challanges
+	  (phase1="sim_min_num_chal=3" can be used to require three challenges)
+	* added support for configuring DH/DSA parameters for an ephemeral DH
+	  key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
+	  dh_file and dh_file2 (phase 2); this adds support for using DSA keys
+	  and optional DH key exchange to achieve forward secracy with RSA keys
+	* added support for matching subject of the authentication server
+	  certificate with a substring when using EAP-TLS/PEAP/TTLS; new
+	  configuration variables subject_match and subject_match2
+	* changed SSID configuration in driver_wext.c (used by many driver
+	  interfaces) to use ssid_len+1 as the length for SSID since some Linux
+	  drivers expect this
+	* fixed couple of unaligned reads in scan result parsing to fix WPA
+	  connection on some platforms (e.g., ARM)
+	* added driver interface for Intel ipw2100 driver
+	* added support for LEAP with WPA
+	* added support for larger scan results report (old limit was 4 kB of
+	  data, i.e., about 35 or so APs) when using Linux wireless extensions
+	  v17 or newer
+	* fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
+	  only if there is a PMKSA cache entry for the current AP
+	* fixed error handling for case where reading of scan results fails:
+	  must schedule a new scan or wpa_supplicant will remain waiting
+	  forever
+	* changed debug output to remove shared password/key material by
+	  default; all key information can be included with -K command line
+	  argument to match the previous behavior
+	* added support for timestamping debug log messages (disabled by
+	  default, can be enabled with -t command line argument)
+	* set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
+	  if keys are not configured to be used; this fixes IEEE 802.1X mode
+	  with drivers that use this information to configure whether Privacy
+	  bit can be in Beacon frames (e.g., ndiswrapper)
+	* avoid clearing driver keys if no keys have been configured since last
+	  key clear request; this seems to improve reliability of group key
+	  handshake for ndiswrapper & NDIS driver which seems to be suffering
+	  of some kind of timing issue when the keys are cleared again after
+	  association
+	* changed driver interface API:
+	  - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
+	    version is being used (now, this is set to 2; previously, it was
+	    not defined)
+	  - pass pointer to private data structure to all calls
+	  - the new API is not backwards compatible; all in-tree driver
+	    interfaces has been converted to the new API
+	* added support for controlling multiple interfaces (radios) per
+	  wpa_supplicant process; each interface needs to be listed on the
+	  command line (-c, -i, -D arguments) with -N as a separator
+	  (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
+	* added a workaround for EAP servers that incorrectly use same Id for
+	  sequential EAP packets
+	* changed libpcap/libdnet configuration to use .config variable,
+	  CONFIG_DNET_PCAP, instead of requiring Makefile modification
+	* improved downgrade attack detection in IE verification of msg 3/4:
+	  verify both WPA and RSN IEs, if present, not only the selected one;
+	  reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
+	  Probe Response frame, and RSN is enabled in wpa_supplicant
+	  configuration
+	* fixed WPA msg 3/4 processing to allow Key Data field contain other
+	  IEs than just one WPA IE
+	* added support for FreeBSD and driver interface for the BSD net80211
+	  layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
+	  required kernel mods have not yet been committed
+	* made EAP workarounds configurable; enabled by default, can be
+	  disabled with network block option eap_workaround=0
+
+2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
+	* resolved couple of interoperability issues with EAP-PEAPv1 and
+	  Phase 2 (inner EAP) fragment reassembly
+	* driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
+	  AP is using non-zero key index for the unicast key and key index zero
+	  for the broadcast key
+	* driver_hostap: fixed IEEE 802.1X WEP key updates and
+	  re-authentication by allowing unencrypted EAPOL frames when not using
+	  WPA
+	* added a new driver interface, 'wext', which uses only standard,
+	  driver independent functionality in Linux wireless extensions;
+	  currently, this can be used only for non-WPA IEEE 802.1X mode, but
+	  eventually, this is to be extended to support full WPA/WPA2 once
+	  Linux wireless extensions get support for this
+	* added support for mode in which the driver is responsible for AP
+	  scanning and selection; this is disabled by default and can be
+	  enabled with global ap_scan=0 variable in wpa_supplicant.conf;
+	  this mode can be used, e.g., with generic 'wext' driver interface to
+	  use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
+	  supporting wireless extensions.
+	* driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
+	  operation with an AP that does not include SSID in the Beacon frames)
+	* added support for new EAP authentication methods:
+	  EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
+	* added support for asking one-time-passwords from frontends (e.g.,
+	  wpa_cli); this 'otp' command works otherwise like 'password' command,
+	  but the password is used only once and the frontend will be asked for
+	  a new password whenever a request from authenticator requires a
+	  password; this can be used with both EAP-OTP and EAP-GTC
+	* changed wpa_cli to automatically re-establish connection so that it
+	  does not need to be re-started when wpa_supplicant is terminated and
+	  started again
+	* improved user data (identity/password/otp) requests through
+	  frontends: process pending EAPOL packets after getting new
+	  information so that full authentication does not need to be
+	  restarted; in addition, send pending requests again whenever a new
+	  frontend is attached
+	* changed control frontends to use a new directory for socket files to
+	  make it easier for wpa_cli to automatically select between interfaces
+	  and to provide access control for the control interface;
+	  wpa_supplicant.conf: ctrl_interface is now a path
+	  (/var/run/wpa_supplicant is the recommended path) and
+	  ctrl_interface_group can be used to select which group gets access to
+	  the control interface;
+	  wpa_cli: by default, try to connect to the first interface available
+	  in /var/run/wpa_supplicant; this path can be overriden with -p option
+	  and an interface can be selected with -i option (i.e., in most common
+	  cases, wpa_cli does not need to get any arguments)
+	* added support for LEAP
+	* added driver interface for Linux ndiswrapper
+	* added priority option for network blocks in the configuration file;
+	  this allows networks to be grouped based on priority (the scan
+	  results are searched for matches with network blocks in this order)
+
+2004-06-20 - v0.2.3
+	* sort scan results to improve AP selection
+	* fixed control interface socket removal for some error cases
+	* improved scan requesting and authentication timeout
+	* small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
+	  TLS processing
+	* PEAP version can now be forced with phase1="peapver=<ver>"
+	  (mostly for testing; by default, the highest version supported by
+	  both the Supplicant and Authentication Server is selected
+	  automatically)
+	* added support for madwifi driver (Atheros ar521x)
+	* added a workaround for cases where AP sets Install Tx/Rx bit for
+	  WPA Group Key messages when pairwise keys are used (without this,
+	  the Group Key would be used for Tx and the AP would drop frames
+	  from the station)
+	* added GSM SIM/USIM interface for GSM authentication algorithm for
+	  EAP-SIM; this requires pcsc-lite
+	* added support for ATMEL AT76C5XXx driver
+	* fixed IEEE 802.1X WEP key derivation in the case where Authenticator
+	  does not include key data in the EAPOL-Key frame (i.e., part of
+	  EAP keying material is used as data encryption key)
+	* added support for using plaintext and static WEP networks
+	  (key_mgmt=NONE)
+
+2004-05-31 - v0.2.2
+	* added support for new EAP authentication methods:
+	  EAP-TTLS/EAP-MD5-Challenge
+	  EAP-TTLS/EAP-GTC
+	  EAP-TTLS/EAP-MSCHAPv2
+	  EAP-TTLS/EAP-TLS
+	  EAP-TTLS/MSCHAPv2
+	  EAP-TTLS/MSCHAP
+	  EAP-TTLS/PAP
+	  EAP-TTLS/CHAP
+	  EAP-PEAP/TLS
+	  EAP-PEAP/GTC
+	  EAP-PEAP/MD5-Challenge
+	  EAP-GTC
+	  EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
+	* added support for anonymous identity (to be used when identity is
+	  sent in plaintext; real identity will be used within TLS protected
+	  tunnel (e.g., with EAP-TTLS)
+	* added event messages from wpa_supplicant to frontends, e.g., wpa_cli
+	* added support for requesting identity and password information using
+	  control interface; in other words, the password for EAP-PEAP or
+	  EAP-TTLS does not need to be included in the configuration file since
+	  a frontand (e.g., wpa_cli) can ask it from the user
+	* improved RSN pre-authentication to use a candidate list and process
+	  all candidates from each scan; not only one per scan
+	* fixed RSN IE and WPA IE capabilities field parsing
+	* ignore Tx bit in GTK IE when Pairwise keys are used
+	* avoid making new scan requests during IEEE 802.1X negotiation
+	* use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
+	  with TLS support (this replaces the included implementation with
+	  library code to save about 8 kB since the library code is needed
+	  anyway for TLS)
+	* fixed WPA-PSK only mode when compiled without IEEE 802.1X support
+	  (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
+
+2004-05-06 - v0.2.1
+	* added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
+	  Supplicant
+	  - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
+	  - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
+	  - EAP-MD5 (cannot be used with WPA-RADIUS)
+	    [draft-ietf-eap-rfc2284bis-09.txt]
+	  - EAP-TLS [RFC 2716]
+	  - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
+	  - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
+	    [draft-kamath-pppext-eap-mschapv2-00.txt]
+	    (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
+	    default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
+	  - new configuration file options: eap, identity, password, ca_cert,
+	    client_cert, privatekey, private_key_passwd
+	  - Xsupplicant is not required anymore, but it can be used by
+	    disabling the internal IEEE 802.1X Supplicant with -e command line
+	    option
+	  - this code is not included in the default build; Makefile need to
+	    be edited for this (uncomment lines for selected functionality)
+	  - EAP-TLS and EAP-PEAP require openssl libraries
+	* use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
+	* added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
+	  (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
+	   EAPOL-Key frames instead of WPA key handshakes)
+	* added support for IEEE 802.11i/RSN (WPA2)
+	  - improved PTK Key Handshake
+	  - PMKSA caching, pre-authentication
+	* fixed wpa_supplicant to ignore possible extra data after WPA
+	  EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
+	  TPTK' error from message 3 of 4-Way Handshake in case the AP
+	  includes extra data after the EAPOL-Key)
+	* added interface for external programs (frontends) to control
+	  wpa_supplicant
+	  - CLI example (wpa_cli) with interactive mode and command line
+	    mode
+	  - replaced SIGUSR1 status/statistics with the new control interface
+	* made some feature compile time configurable
+	  - .config file for make
+	  - driver interfaces (hostap, hermes, ..)
+	  - EAPOL/EAP functions
+
+2004-02-15 - v0.2.0
+	* Initial version of wpa_supplicant

+
+Requirements
+------------
+
+Current hardware/software requirements:
+- Linux kernel 2.4.x or 2.6.x with Linux Wireless Extensions v15 or newer
+- FreeBSD 6-CURRENT
+- NetBSD-current
+- Microsoft Windows with WinPcap (at least WinXP, may work with other versions)
+- drivers:
+	Linux drivers that support WPA/WPA2 configuration with the generic
+	Linux wireless extensions (WE-18 or newer). Even though there are
+	number of driver specific interface included in wpa_supplicant, please
+	note that Linux drivers are moving to use generic wireless extensions
+	and driver_wext (-Dwext on wpa_supplicant command line) should be the
+	default option to start with before falling back to driver specific
+	interface.
+
+	Host AP driver for Prism2/2.5/3 (development snapshot/v0.2.x)
+	(http://hostap.epitest.fi/)
+	Driver need to be set in Managed mode ('iwconfig wlan0 mode managed').
+	Please note that station firmware version needs to be 1.7.0 or newer
+	to work in WPA mode.
+
+	Linuxant DriverLoader (http://www.linuxant.com/driverloader/)
+	with Windows NDIS driver for your wlan card supporting WPA.
+
+	Agere Systems Inc. Linux Driver
+	(http://www.agere.com/support/drivers/)
+	Please note that the driver interface file (driver_hermes.c) and
+	hardware specific include files are not included in the
+	wpa_supplicant distribution. You will need to copy these from the
+	source package of the Agere driver.
+
+	madwifi driver for cards based on Atheros chip set (ar521x)
+	(http://sourceforge.net/projects/madwifi/)
+	Please note that you will need to modify the wpa_supplicant .config
+	file to use the correct path for the madwifi driver root directory
+	(CFLAGS += -I../madwifi/wpa line in example defconfig).
+
+	ATMEL AT76C5XXx driver for USB and PCMCIA cards
+	(http://atmelwlandriver.sourceforge.net/).
+
+	Linux ndiswrapper (http://ndiswrapper.sourceforge.net/) with
+	Windows NDIS driver.
+
+	Broadcom wl.o driver (old version only)
+	This is a generic Linux driver for Broadcom IEEE 802.11a/g cards.
+	However, it is proprietary driver that is not publicly available
+	except for couple of exceptions, mainly Broadcom-based APs/wireless
+	routers that use Linux. The driver binary can be downloaded, e.g.,
+	from Linksys support site (http://www.linksys.com/support/gpl.asp)
+	for Linksys WRT54G. The GPL tarball includes cross-compiler and
+	the needed header file, wlioctl.h, for compiling wpa_supplicant.
+	This driver support in wpa_supplicant is expected to work also with
+	other devices based on Broadcom driver (assuming the driver includes
+	client mode support). Please note that the newer Broadcom driver
+	("hybrid Linux driver") supports Linux wireless extensions and does
+	not need (or even work) with the specific driver wrapper. Use -Dwext
+	with that driver.
+
+	Intel ipw2100 driver
+	(http://sourceforge.net/projects/ipw2100/)
+
+	Intel ipw2200 driver
+	(http://sourceforge.net/projects/ipw2200/)
+
+	In theory, any driver that supports Linux wireless extensions can be
+	used with IEEE 802.1X (i.e., not WPA) when using ap_scan=0 option in
+	configuration file.
+
+	Wired Ethernet drivers (with ap_scan=0)
+
+	BSD net80211 layer (e.g., Atheros driver)
+	At the moment, this is for FreeBSD 6-CURRENT branch and NetBSD-current.
+
+	Windows NDIS
+	The current Windows port requires WinPcap (http://winpcap.polito.it/).
+	See README-Windows.txt for more information.
+
+wpa_supplicant was designed to be portable for different drivers and
+operating systems. Hopefully, support for more wlan cards and OSes will be
+added in the future. See developer's documentation
+(http://hostap.epitest.fi/wpa_supplicant/devel/) for more information about the
+design of wpa_supplicant and porting to other drivers. One main goal
+is to add full WPA/WPA2 support to Linux wireless extensions to allow
+new drivers to be supported without having to implement new
+driver-specific interface code in wpa_supplicant.
+
+Optional libraries for layer2 packet processing:
+- libpcap (tested with 0.7.2, most relatively recent versions assumed to work,
+	this is likely to be available with most distributions,
+	http://tcpdump.org/)
+- libdnet (tested with v1.4, most versions assumed to work,
+	http://libdnet.sourceforge.net/)
+
+These libraries are _not_ used in the default Linux build. Instead,
+internal Linux specific implementation is used. libpcap/libdnet are
+more portable and they can be used by adding CONFIG_L2_PACKET=pcap into
+.config. They may also be selected automatically for other operating
+systems. In case of Windows builds, WinPcap is used by default
+(CONFIG_L2_PACKET=winpcap).
+
+
+Optional libraries for EAP-TLS, EAP-PEAP, and EAP-TTLS:
+- OpenSSL (tested with 0.9.7c and 0.9.7d, and 0.9.8 versions; assumed to
+  work with most relatively recent versions; this is likely to be
+  available with most distributions, http://www.openssl.org/)
+- GnuTLS
+- internal TLSv1 implementation
+
+TLS options for EAP-FAST:
+- OpenSSL 0.9.8d _with_ openssl-0.9.8d-tls-extensions.patch applied
+  (i.e., the default OpenSSL package does not include support for
+  extensions needed for EAP-FAST)
+- internal TLSv1 implementation
+
+One of these libraries is needed when EAP-TLS, EAP-PEAP, EAP-TTLS, or
+EAP-FAST support is enabled. WPA-PSK mode does not require this or EAPOL/EAP
+implementation. A configuration file, .config, for compilation is
+needed to enable IEEE 802.1X/EAPOL and EAP methods. Note that EAP-MD5,
+EAP-GTC, EAP-OTP, and EAP-MSCHAPV2 cannot be used alone with WPA, so
+they should only be enabled if testing the EAPOL/EAP state
+machines. However, there can be used as inner authentication
+algorithms with EAP-PEAP and EAP-TTLS.
+
+See Building and installing section below for more detailed
+information about the wpa_supplicant build time configuration.
+
+
+
+WPA
+---
+
+The original security mechanism of IEEE 802.11 standard was not
+designed to be strong and has proven to be insufficient for most
+networks that require some kind of security. Task group I (Security)
+of IEEE 802.11 working group (http://www.ieee802.org/11/) has worked
+to address the flaws of the base standard and has in practice
+completed its work in May 2004. The IEEE 802.11i amendment to the IEEE
+802.11 standard was approved in June 2004 and published in July 2004.
+
+Wi-Fi Alliance (http://www.wi-fi.org/) used a draft version of the
+IEEE 802.11i work (draft 3.0) to define a subset of the security
+enhancements that can be implemented with existing wlan hardware. This
+is called Wi-Fi Protected Access<TM> (WPA). This has now become a
+mandatory component of interoperability testing and certification done
+by Wi-Fi Alliance. Wi-Fi provides information about WPA at its web
+site (http://www.wi-fi.org/OpenSection/protected_access.asp).
+
+IEEE 802.11 standard defined wired equivalent privacy (WEP) algorithm
+for protecting wireless networks. WEP uses RC4 with 40-bit keys,
+24-bit initialization vector (IV), and CRC32 to protect against packet
+forgery. All these choices have proven to be insufficient: key space is
+too small against current attacks, RC4 key scheduling is insufficient
+(beginning of the pseudorandom stream should be skipped), IV space is
+too small and IV reuse makes attacks easier, there is no replay
+protection, and non-keyed authentication does not protect against bit
+flipping packet data.
+
+WPA is an intermediate solution for the security issues. It uses
+Temporal Key Integrity Protocol (TKIP) to replace WEP. TKIP is a
+compromise on strong security and possibility to use existing
+hardware. It still uses RC4 for the encryption like WEP, but with
+per-packet RC4 keys. In addition, it implements replay protection,
+keyed packet authentication mechanism (Michael MIC).
+
+Keys can be managed using two different mechanisms. WPA can either use
+an external authentication server (e.g., RADIUS) and EAP just like
+IEEE 802.1X is using or pre-shared keys without need for additional
+servers. Wi-Fi calls these "WPA-Enterprise" and "WPA-Personal",
+respectively. Both mechanisms will generate a master session key for
+the Authenticator (AP) and Supplicant (client station).
+
+WPA implements a new key handshake (4-Way Handshake and Group Key
+Handshake) for generating and exchanging data encryption keys between
+the Authenticator and Supplicant. This handshake is also used to
+verify that both Authenticator and Supplicant know the master session
+key. These handshakes are identical regardless of the selected key
+management mechanism (only the method for generating master session
+key changes).
+
+
+
+IEEE 802.11i / WPA2
+-------------------
+
+The design for parts of IEEE 802.11i that were not included in WPA has
+finished (May 2004) and this amendment to IEEE 802.11 was approved in
+June 2004. Wi-Fi Alliance is using the final IEEE 802.11i as a new
+version of WPA called WPA2. This includes, e.g., support for more
+robust encryption algorithm (CCMP: AES in Counter mode with CBC-MAC)
+to replace TKIP and optimizations for handoff (reduced number of
+messages in initial key handshake, pre-authentication, and PMKSA caching).
+
+
+
+wpa_supplicant
+--------------
+
+wpa_supplicant is an implementation of the WPA Supplicant component,
+i.e., the part that runs in the client stations. It implements WPA key
+negotiation with a WPA Authenticator and EAP authentication with
+Authentication Server. In addition, it controls the roaming and IEEE
+802.11 authentication/association of the wlan driver.
+
+wpa_supplicant is designed to be a "daemon" program that runs in the
+background and acts as the backend component controlling the wireless
+connection. wpa_supplicant supports separate frontend programs and an
+example text-based frontend, wpa_cli, is included with wpa_supplicant.
+
+Following steps are used when associating with an AP using WPA:
+
+- wpa_supplicant requests the kernel driver to scan neighboring BSSes
+- wpa_supplicant selects a BSS based on its configuration
+- wpa_supplicant requests the kernel driver to associate with the chosen
+  BSS
+- If WPA-EAP: integrated IEEE 802.1X Supplicant completes EAP
+  authentication with the authentication server (proxied by the
+  Authenticator in the AP)
+- If WPA-EAP: master key is received from the IEEE 802.1X Supplicant
+- If WPA-PSK: wpa_supplicant uses PSK as the master session key
+- wpa_supplicant completes WPA 4-Way Handshake and Group Key Handshake
+  with the Authenticator (AP)
+- wpa_supplicant configures encryption keys for unicast and broadcast
+- normal data packets can be transmitted and received
+
+
+
+Building and installing
+-----------------------
+
+In order to be able to build wpa_supplicant, you will first need to
+select which parts of it will be included. This is done by creating a
+build time configuration file, .config, in the wpa_supplicant root
+directory. Configuration options are text lines using following
+format: CONFIG_<option>=y. Lines starting with # are considered
+comments and are ignored. See defconfig file for an example configuration
+and a list of available options and additional notes.
+
+The build time configuration can be used to select only the needed
+features and limit the binary size and requirements for external
+libraries. The main configuration parts are the selection of which
+driver interfaces (e.g., hostap, madwifi, ..) and which authentication
+methods (e.g., EAP-TLS, EAP-PEAP, ..) are included.
+
+Following build time configuration options are used to control IEEE
+802.1X/EAPOL and EAP state machines and all EAP methods. Including
+TLS, PEAP, or TTLS will require linking wpa_supplicant with OpenSSL
+library for TLS implementation. Alternatively, GnuTLS or the internal
+TLSv1 implementation can be used for TLS functionaly.
+
+CONFIG_IEEE8021X_EAPOL=y
+CONFIG_EAP_MD5=y

+
+
+After you have created a configuration file, you can build
+wpa_supplicant and wpa_cli with 'make' command. You may then install
+the binaries to a suitable system directory, e.g., /usr/local/bin.
+
+Example commands:
+
+# build wpa_supplicant and wpa_cli
+make
+# install binaries (this may need root privileges)
+cp wpa_cli wpa_supplicant /usr/local/bin
+
+
+You will need to make a configuration file, e.g.,
+/etc/wpa_supplicant.conf, with network configuration for the networks
+you are going to use. Configuration file section below includes
+explanation fo the configuration file format and includes various
+examples. Once the configuration is ready, you can test whether the
+configuration work by first running wpa_supplicant with following
+command to start it on foreground with debugging enabled:
+
+wpa_supplicant -iwlan0 -c/etc/wpa_supplicant.conf -d
+
+Assuming everything goes fine, you can start using following command
+to start wpa_supplicant on background without debugging:
+
+wpa_supplicant -iwlan0 -c/etc/wpa_supplicant.conf -B
+
+Please note that if you included more than one driver interface in the
+build time configuration (.config), you may need to specify which
+interface to use by including -D<driver name> option on the command
+line. See following section for more details on command line options
+for wpa_supplicant.
+
+
+
+Command line options
+--------------------
+
+usage:
+  wpa_supplicant [-BddfhKLqqtuvwW] [-P<pid file>] [-g<global ctrl>] \
+        -i<ifname> -c<config file> [-C<ctrl>] [-D<driver>] [-p<driver_param>] \
+        [-b<br_ifname> [-N -i<ifname> -c<conf> [-C<ctrl>] [-D<driver>] \
+        [-p<driver_param>] [-b<br_ifname>] ...]
+
+options:
+  -b = optional bridge interface name
+  -B = run daemon in the background
+  -c = Configuration file
+  -C = ctrl_interface parameter (only used if -c is not)
+  -i = interface name
+  -d = increase debugging verbosity (-dd even more)
+  -D = driver name
+  -f = Log output to default log location (normally /tmp)
+  -g = global ctrl_interface
+  -K = include keys (passwords, etc.) in debug output
+  -t = include timestamp in debug messages
+  -h = show this help text
+  -L = show license (GPL and BSD)
+  -p = driver parameters
+  -P = PID file
+  -q = decrease debugging verbosity (-qq even less)
+  -u = enable DBus control interface
+  -v = show version
+  -w = wait for interface to be added, if needed
+  -W = wait for a control interface monitor before starting
+  -N = start describing new interface
+
+drivers:
+  hostap = Host AP driver (Intersil Prism2/2.5/3) [default]
+	(this can also be used with Linuxant DriverLoader)
+  hermes = Agere Systems Inc. driver (Hermes-I/Hermes-II)
+  madwifi = MADWIFI 802.11 support (Atheros, etc.)
+  atmel = ATMEL AT76C5XXx (USB, PCMCIA)
+  wext = Linux wireless extensions (generic)
+  ralink = Ralink Client driver
+  ndiswrapper = Linux ndiswrapper
+  broadcom = Broadcom wl.o driver
+  ipw = Intel ipw2100/2200 driver (old; use wext with Linux 2.6.13 or newer)
+  wired = wpa_supplicant wired Ethernet driver
+  roboswitch = wpa_supplicant Broadcom switch driver
+  bsd = BSD 802.11 support (Atheros, etc.)
+  ndis = Windows NDIS driver
+
+In most common cases, wpa_supplicant is started with
+
+wpa_supplicant -B -c/etc/wpa_supplicant.conf -iwlan0
+
+This makes the process fork into background.
+
+The easiest way to debug problems, and to get debug log for bug
+reports, is to start wpa_supplicant on foreground with debugging
+enabled:
+
+wpa_supplicant -c/etc/wpa_supplicant.conf -iwlan0 -d
+
+
+wpa_supplicant can control multiple interfaces (radios) either by
+running one process for each interface separately or by running just
+one process and list of options at command line. Each interface is
+separated with -N argument. As an example, following command would
+start wpa_supplicant for two interfaces:
+
+wpa_supplicant \
+	-c wpa1.conf -i wlan0 -D hostap -N \
+	-c wpa2.conf -i ath0 -D madwifi
+
+
+If the interface is added in a Linux bridge (e.g., br0), the bridge
+interface needs to be configured to wpa_supplicant in addition to the
+main interface:
+
+wpa_supplicant -cw.conf -Dmadwifi -iath0 -bbr0
+
+
+Configuration file
+------------------
+
+wpa_supplicant is configured using a text file that lists all accepted
+networks and security policies, including pre-shared keys. See
+example configuration file, wpa_supplicant.conf, for detailed
+information about the configuration format and supported fields.
+
+Changes to configuration file can be reloaded be sending SIGHUP signal
+to wpa_supplicant ('killall -HUP wpa_supplicant'). Similarly,
+reloading can be triggered with 'wpa_cli reconfigure' command.
+
+Configuration file can include one or more network blocks, e.g., one
+for each used SSID. wpa_supplicant will automatically select the best
+betwork based on the order of network blocks in the configuration
+file, network security level (WPA/WPA2 is preferred), and signal
+strength.
+
+Example configuration files for some common configurations:
+
+1) WPA-Personal (PSK) as home network and WPA-Enterprise with EAP-TLS as work
+   network
+
+# allow frontend (e.g., wpa_cli) to be used by all users in 'wheel' group
+ctrl_interface=/var/run/wpa_supplicant
+ctrl_interface_group=wheel
+#
+# home network; allow all valid ciphers
+network={
+	ssid="home"
+	scan_ssid=1
+	key_mgmt=WPA-PSK
+	psk="very secret passphrase"
+}
+#
+# work network; use EAP-TLS with WPA; allow only CCMP and TKIP ciphers
+network={
+	ssid="work"
+	scan_ssid=1
+	key_mgmt=WPA-EAP
+	pairwise=CCMP TKIP
+	group=CCMP TKIP
+	eap=TLS
+	identity="user@example.com"
+	ca_cert="/etc/cert/ca.pem"
+	client_cert="/etc/cert/user.pem"
+	private_key="/etc/cert/user.prv"
+	private_key_passwd="password"
+}
+
+
+2) WPA-RADIUS/EAP-PEAP/MSCHAPv2 with RADIUS servers that use old peaplabel
+   (e.g., Funk Odyssey and SBR, Meetinghouse Aegis, Interlink RAD-Series)
+
+ctrl_interface=/var/run/wpa_supplicant
+ctrl_interface_group=wheel
+network={
+	ssid="example"
+	scan_ssid=1
+	key_mgmt=WPA-EAP
+	eap=PEAP
+	identity="user@example.com"
+	password="foobar"
+	ca_cert="/etc/cert/ca.pem"
+	phase1="peaplabel=0"
+	phase2="auth=MSCHAPV2"
+}
+
+
+3) EAP-TTLS/EAP-MD5-Challenge configuration with anonymous identity for the
+   unencrypted use. Real identity is sent only within an encrypted TLS tunnel.
+
+ctrl_interface=/var/run/wpa_supplicant
+ctrl_interface_group=wheel
+network={
+	ssid="example"
+	scan_ssid=1
+	key_mgmt=WPA-EAP
+	eap=TTLS
+	identity="user@example.com"
+	anonymous_identity="anonymous@example.com"
+	password="foobar"
+	ca_cert="/etc/cert/ca.pem"
+	phase2="auth=MD5"
+}
+
+
+4) IEEE 802.1X (i.e., no WPA) with dynamic WEP keys (require both unicast and
+   broadcast); use EAP-TLS for authentication
+
+ctrl_interface=/var/run/wpa_supplicant
+ctrl_interface_group=wheel
+network={
+	ssid="1x-test"
+	scan_ssid=1
+	key_mgmt=IEEE8021X
+	eap=TLS
+	identity="user@example.com"
+	ca_cert="/etc/cert/ca.pem"
+	client_cert="/etc/cert/user.pem"
+	private_key="/etc/cert/user.prv"
+	private_key_passwd="password"
+	eapol_flags=3
+}
+
+
+5) Catch all example that allows more or less all configuration modes. The
+   configuration options are used based on what security policy is used in the
+   selected SSID. This is mostly for testing and is not recommended for normal
+   use.
+
+ctrl_interface=/var/run/wpa_supplicant
+ctrl_interface_group=wheel
+network={
+	ssid="example"
+	scan_ssid=1
+	key_mgmt=WPA-EAP WPA-PSK IEEE8021X NONE
+	pairwise=CCMP TKIP
+	group=CCMP TKIP WEP104 WEP40
+	psk="very secret passphrase"
+	eap=TTLS PEAP TLS
+	identity="user@example.com"
+	password="foobar"
+	ca_cert="/etc/cert/ca.pem"
+	client_cert="/etc/cert/user.pem"
+	private_key="/etc/cert/user.prv"
+	private_key_passwd="password"
+	phase1="peaplabel=0"
+	ca_cert2="/etc/cert/ca2.pem"
+	client_cert2="/etc/cer/user.pem"
+	private_key2="/etc/cer/user.prv"
+	private_key2_passwd="password"
+}
+
+
+6) Authentication for wired Ethernet. This can be used with 'wired' or
+   'roboswitch' interface (-Dwired or -Droboswitch on command line).
+
+ctrl_interface=/var/run/wpa_supplicant
+ctrl_interface_group=wheel
+ap_scan=0
+network={
+	key_mgmt=IEEE8021X
+	eap=MD5
+	identity="user"
+	password="password"
+	eapol_flags=0
+}
+
+
+
+Certificates
+------------
+
+Some EAP authentication methods require use of certificates. EAP-TLS
+uses both server side and client certificates whereas EAP-PEAP and
+EAP-TTLS only require the server side certificate. When client
+certificate is used, a matching private key file has to also be
+included in configuration. If the private key uses a passphrase, this
+has to be configured in wpa_supplicant.conf ("private_key_passwd").
+
+wpa_supplicant supports X.509 certificates in PEM and DER
+formats. User certificate and private key can be included in the same
+file.
+
+If the user certificate and private key is received in PKCS#12/PFX
+format, they need to be converted to suitable PEM/DER format for
+wpa_supplicant. This can be done, e.g., with following commands:
+
+# convert client certificate and private key to PEM format
+openssl pkcs12 -in example.pfx -out user.pem -clcerts
+# convert CA certificate (if included in PFX file) to PEM format
+openssl pkcs12 -in example.pfx -out ca.pem -cacerts -nokeys
+
+
+
+wpa_cli
+-------
+
+wpa_cli is a text-based frontend program for interacting with
+wpa_supplicant. It is used to query current status, change
+configuration, trigger events, and request interactive user input.
+
+wpa_cli can show the current authentication status, selected security
+mode, dot11 and dot1x MIBs, etc. In addition, it can configure some
+variables like EAPOL state machine parameters and trigger events like
+reassociation and IEEE 802.1X logoff/logon. wpa_cli provides a user
+interface to request authentication information, like username and
+password, if these are not included in the configuration. This can be
+used to implement, e.g., one-time-passwords or generic token card
+authentication where the authentication is based on a
+challenge-response that uses an external device for generating the
+response.
+
+The control interface of wpa_supplicant can be configured to allow
+non-root user access (ctrl_interface_group in the configuration
+file). This makes it possible to run wpa_cli with a normal user
+account.
+
+wpa_cli supports two modes: interactive and command line. Both modes
+share the same command set and the main difference is in interactive
+mode providing access to unsolicited messages (event messages,
+username/password requests).
+
+Interactive mode is started when wpa_cli is executed without including
+the command as a command line parameter. Commands are then entered on
+the wpa_cli prompt. In command line mode, the same commands are
+entered as command line arguments for wpa_cli.
+
+
+Interactive authentication parameters request
+
+When wpa_supplicant need authentication parameters, like username and
+password, which are not present in the configuration file, it sends a
+request message to all attached frontend programs, e.g., wpa_cli in
+interactive mode. wpa_cli shows these requests with
+"CTRL-REQ-<type>-<id>:<text>" prefix. <type> is IDENTITY, PASSWORD, or
+OTP (one-time-password). <id> is a unique identifier for the current
+network. <text> is description of the request. In case of OTP request,
+it includes the challenge from the authentication server.
+
+The reply to these requests can be given with 'identity', 'password',
+and 'otp' commands. <id> needs to be copied from the the matching
+request. 'password' and 'otp' commands can be used regardless of
+whether the request was for PASSWORD or OTP. The main difference
+between these two commands is that values given with 'password' are
+remembered as long as wpa_supplicant is running whereas values given
+with 'otp' are used only once and then forgotten, i.e., wpa_supplicant
+will ask frontend for a new value for every use. This can be used to
+implement one-time-password lists and generic token card -based
+authentication.
+
+Example request for password and a matching reply:
+
+CTRL-REQ-PASSWORD-1:Password needed for SSID foobar
+> password 1 mysecretpassword
+
+Example request for generic token card challenge-response:
+
+CTRL-REQ-OTP-2:Challenge 1235663 needed for SSID foobar
+> otp 2 9876

+
+
+Using wpa_cli to run external program on connect/disconnect
+-----------------------------------------------------------
+
+wpa_cli can used to run external programs whenever wpa_supplicant
+connects or disconnects from a network. This can be used, e.g., to
+update network configuration and/or trigget DHCP client to update IP
+addresses, etc.
+
+One wpa_cli process in "action" mode needs to be started for each
+interface. For example, the following command starts wpa_cli for the
+default ingterface (-i can be used to select the interface in case of
+more than one interface being used at the same time):
+
+wpa_cli -a/sbin/wpa_action.sh -B
+
+The action file (-a option, /sbin/wpa_action.sh in this example) will
+be executed whenever wpa_supplicant completes authentication (connect
+event) or detects disconnection). The action script will be called
+with two command line arguments: interface name and event (CONNECTED
+or DISCONNECTED). If the action script needs to get more information
+about the current network, it can use 'wpa_cli status' to query
+wpa_supplicant for more information.
+
+Following example can be used as a simple template for an action
+script:
+
+#!/bin/sh
+
+IFNAME=$1
+CMD=$2
+
+if [ "$CMD" == "CONNECTED" ]; then
+    SSID=`wpa_cli -i$IFNAME status | grep ^ssid= | cut -f2- -d=`
+    # configure network, signal DHCP client, etc.
+fi
+
+if [ "$CMD" == "DISCONNECTED" ]; then
+    # remove network configuration, if needed
+fi
+
+
+
+Integrating with pcmcia-cs/cardmgr scripts
+------------------------------------------
+
+wpa_supplicant needs to be running when using a wireless network with
+WPA. It can be started either from system startup scripts or from
+pcmcia-cs/cardmgr scripts (when using PC Cards). WPA handshake must be
+completed before data frames can be exchanged, so wpa_supplicant
+should be started before DHCP client.
+
+For example, following small changes to pcmcia-cs scripts can be used
+to enable WPA support:
+
+Add MODE="Managed" and WPA="y" to the network scheme in
+/etc/pcmcia/wireless.opts.
+
+Add the following block to the end of 'start' action handler in
+/etc/pcmcia/wireless:
+
+    if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
+	/usr/local/bin/wpa_supplicant -B -c/etc/wpa_supplicant.conf \
+		-i$DEVICE
+    fi
+
+Add the following block to the end of 'stop' action handler (may need
+to be separated from other actions) in /etc/pcmcia/wireless:
+
+    if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
+	killall wpa_supplicant
+    fi
+
+This will make cardmgr start wpa_supplicant when the card is plugged
+in.
+
+
+
+Dynamic interface add and operation without configuration files
+---------------------------------------------------------------
+
+wpa_supplicant can be started without any configuration files or
+network interfaces. When used in this way, a global (i.e., per
+wpa_supplicant process) control interface is used to add and remove
+network interfaces. Each network interface can then be configured
+through a per-network interface control interface. For example,
+following commands show how to start wpa_supplicant without any
+network interfaces and then add a network interface and configure a
+network (SSID):
+
+# Start wpa_supplicant in the background
+wpa_supplicant -g/var/run/wpa_supplicant-global -B
+
+# Add a new interface (wlan0, no configuration file, driver=wext, and
+# enable control interface)
+wpa_cli -g/var/run/wpa_supplicant-global interface_add wlan0 \
+	"" wext /var/run/wpa_supplicant
+
+# Configure a network using the newly added network interface:
+wpa_cli -iwlan0 add_network
+wpa_cli -iwlan0 set_network 0 ssid '"test"'
+wpa_cli -iwlan0 set_network 0 key_mgmt WPA-PSK
+wpa_cli -iwlan0 set_network 0 psk '"12345678"'
+wpa_cli -iwlan0 set_network 0 pairwise TKIP
+wpa_cli -iwlan0 set_network 0 group TKIP
+wpa_cli -iwlan0 set_network 0 proto WPA
+wpa_cli -iwlan0 enable_network 0
+
+# At this point, the new network interface should start trying to associate
+# with the WPA-PSK network using SSID test.
+
+# Remove network interface
+wpa_cli -g/var/run/wpa_supplicant-global interface_remove wlan0
+
+
+Privilege separation
+--------------------
+
+To minimize the size of code that needs to be run with root privileges
+(e.g., to control wireless interface operation), wpa_supplicant
+supports optional privilege separation. If enabled, this separates the
+privileged operations into a separate process (wpa_priv) while leaving
+rest of the code (e.g., EAP authentication and WPA handshakes) into an
+unprivileged process (wpa_supplicant) that can be run as non-root
+user. Privilege separation restricts the effects of potential software
+errors by containing the majority of the code in an unprivileged
+process to avoid full system compromise.
+
+Privilege separation is not enabled by default and it can be enabled
+by adding CONFIG_PRIVSEP=y to the build configuration (.config). When
+enabled, the privileged operations (driver wrapper and l2_packet) are
+linked into a separate daemon program, wpa_priv. The unprivileged
+program, wpa_supplicant, will be built with a special driver/l2_packet
+wrappers that communicate with the privileged wpa_priv process to
+perform the needed operations. wpa_priv can control what privileged
+are allowed.
+
+wpa_priv needs to be run with network admin privileges (usually, root
+user). It opens a UNIX domain socket for each interface that is
+included on the command line; any other interface will be off limits
+for wpa_supplicant in this kind of configuration. After this,
+wpa_supplicant can be run as a non-root user (e.g., all standard users
+on a laptop or as a special non-privileged user account created just
+for this purpose to limit access to user files even further).
+
+
+Example configuration:
+- create user group for users that are allowed to use wpa_supplicant
+  ('wpapriv' in this example) and assign users that should be able to
+  use wpa_supplicant into that group
+- create /var/run/wpa_priv directory for UNIX domain sockets and control
+  user access by setting it accessible only for the wpapriv group:
+  mkdir /var/run/wpa_priv
+  chown root:wpapriv /var/run/wpa_priv
+  chmod 0750 /var/run/wpa_priv
+- start wpa_priv as root (e.g., from system startup scripts) with the
+  enabled interfaces configured on the command line:
+  wpa_priv -B -P /var/run/wpa_priv.pid wext:ath0
+- run wpa_supplicant as non-root with a user that is in wpapriv group:
+  wpa_supplicant -i ath0 -c wpa_supplicant.conf
+
+wpa_priv does not use the network interface before wpa_supplicant is
+started, so it is fine to include network interfaces that are not
+available at the time wpa_priv is started. As an alternative, wpa_priv
+can be started when an interface is added (hotplug/udev/etc. scripts).
+wpa_priv can control multiple interface with one process, but it is
+also possible to run multiple wpa_priv processes at the same time, if
+desired.

+Wi-Fi Protected Setup (WPS) is a mechanism for easy configuration of a
+wireless network. It allows automated generation of random keys (WPA
+passphrase/PSK) and configuration of an access point and client
+devices. WPS includes number of methods for setting up connections
+with PIN method and push-button configuration (PBC) being the most
+commonly deployed options.
+
+While WPS can enable more home networks to use encryption in the
+wireless network, it should be noted that the use of the PIN and
+especially PBC mechanisms for authenticating the initial key setup is
+not very secure. As such, use of WPS may not be suitable for
+environments that require secure network access without chance for
+allowing outsiders to gain access during the setup phase.
+
+WPS uses following terms to describe the entities participating in the
+network setup:
+- access point: the WLAN access point
+- Registrar: a device that control a network and can authorize
+  addition of new devices); this may be either in the AP ("internal
+  Registrar") or in an external device, e.g., a laptop, ("external
+  Registrar")
+- Enrollee: a device that is being authorized to use the network
+
+It should also be noted that the AP and a client device may change
+roles (i.e., AP acts as an Enrollee and client device as a Registrar)
+when WPS is used to configure the access point.
+
+
+More information about WPS is available from Wi-Fi Alliance:
+http://www.wi-fi.org/wifi-protected-setup
+
+
+wpa_supplicant implementation
+-----------------------------
+
+wpa_supplicant includes an optional WPS component that can be used as
+an Enrollee to enroll new network credential or as a Registrar to
+configure an AP. The current version of wpa_supplicant does not
+support operation as an external WLAN Management Registrar for adding
+new client devices or configuring the AP over UPnP.
+
+
+wpa_supplicant configuration
+----------------------------
+
+WPS is an optional component that needs to be enabled in
+wpa_supplicant build configuration (.config). Here is an example
+configuration that includes WPS support and Linux wireless extensions
+-based driver interface:
+
+CONFIG_DRIVER_WEXT=y
+CONFIG_EAP=y
+CONFIG_WPS=y
+
+
+WPS needs the Universally Unique IDentifier (UUID; see RFC 4122) for
+the device. This is configured in the runtime configuration for
+wpa_supplicant (if not set, UUID will be generated based on local MAC
+address):
+
+# example UUID for WPS
+uuid=12345678-9abc-def0-1234-56789abcdef0
+
+The network configuration blocks needed for WPS are added
+automatically based on control interface commands, so they do not need
+to be added explicitly in the configuration file.
+
+WPS registration will generate new network blocks for the acquired
+credentials. If these are to be stored for future use (after
+restarting wpa_supplicant), wpa_supplicant will need to be configured
+to allow configuration file updates:
+
+update_config=1
+
+
+
+External operations
+-------------------
+
+WPS requires either a device PIN code (usually, 8-digit number) or a
+pushbutton event (for PBC) to allow a new WPS Enrollee to join the
+network. wpa_supplicant uses the control interface as an input channel
+for these events.
+
+If the client device has a display, a random PIN has to be generated
+for each WPS registration session. wpa_supplicant can do this with a
+control interface request, e.g., by calling wpa_cli:
+
+wpa_cli wps_pin any
+
+This will return the generated 8-digit PIN which will then need to be
+entered at the Registrar to complete WPS registration. At that point,
+the client will be enrolled with credentials needed to connect to the
+AP to access the network.
+
+
+If the client device does not have a display that could show the
+random PIN, a hardcoded PIN that is printed on a label can be
+used. wpa_supplicant is notified this with a control interface
+request, e.g., by calling wpa_cli:
+
+wpa_cli wps_pin any 12345670
+
+This starts the WPS negotiation in the same way as above with the
+generated PIN.
+
+
+If the client design wants to support optional WPS PBC mode, this can
+be enabled by either a physical button in the client device or a
+virtual button in the user interface. The PBC operation requires that
+a button is also pressed at the AP/Registrar at about the same time (2
+minute window). wpa_supplicant is notified of the local button event
+over the control interface, e.g., by calling wpa_cli:
+
+wpa_cli wps_pbc
+
+At this point, the AP/Registrar has two minutes to complete WPS
+negotiation which will generate a new WPA PSK in the same way as the
+PIN method described above.
+
+
+If the client wants to operation in the Registrar role to configure an
+AP, wpa_supplicant is notified over the control interface, e.g., with
+wpa_cli:
+
+wpa_cli wps_reg <AP BSSID> <AP PIN>
+(example: wpa_cli wps_reg 02:34:56:78:9a:bc 12345670)
+
+
+Scanning
+--------
+
+Scan results ('wpa_cli scan_results' or 'wpa_cli bss <idx>') include a
+flags field that is used to indicate whether the BSS support WPS. If
+the AP support WPS, but has not recently activated a Registrar, [WPS]
+flag will be included. If PIN method has been recently selected,
+[WPS-PIN] is shown instead. Similarly, [WPS-PBC] is shown if PBC mode
+is in progress. GUI programs can use these as triggers for suggesting
+a guided WPS configuration to the user. In addition, control interface
+monitor events WPS-AP-AVAILABLE{,-PBC,-PIN} can be used to find out if
+there are WPS enabled APs in scan results without having to go through
+all the details in the GUI. These notification could be used, e.g., to
+suggest possible WPS connection to the user.
+
+
+wpa_gui
+-------
+
+wpa_gui-qt4 directory contains a sample GUI that shows an example of
+how WPS support can be integrated into the GUI. Its main window has a
+WPS tab that guides user through WPS registration with automatic AP
+selection. In addition, it shows how WPS can be started manually by
+selecting an AP from scan results.
+
+
+Credential processing
+---------------------
+
+By default, wpa_supplicant processes received credentials and updates
+its configuration internally. However, it is possible to
+control these operations from external programs, if desired.
+
+This internal processing can be disabled with wps_cred_processing=1
+option. When this is used, an external program is responsible for
+processing the credential attributes and updating wpa_supplicant
+configuration based on them.
+
+Following control interface messages are sent out for external programs:
+
+WPS-CRED-RECEIVED  <hexdump of Credential attribute(s)>
+For example:
+<2>WPS-CRED-RECEIVED 100e006f10260001011045000c6a6b6d2d7770732d74657374100300020020100f000200081027004030653462303435366332363666653064333961643135353461316634626637313234333761636664623766333939653534663166316230323061643434386235102000060266a0ee1727

+	 * mechanism is used. For all cases, the existance of this parameter
+	 * in configuration is used to determine whether the control interface
+	 * is enabled.
+	 *
+	 * For UNIX domain sockets (default on Linux and BSD): This is a
+	 * directory that will be created for UNIX domain sockets for listening
+	 * to requests from external programs (CLI/GUI, etc.) for status
+	 * information and configuration. The socket file will be named based

+	 *
+	 * Access control for the control interface can be configured
+	 * by setting the directory to allow only members of a group
+	 * to use sockets. This way, it is possible to run
+	 * %wpa_supplicant as root (since it needs to change network
+	 * configuration and open raw sockets) and still allow GUI/CLI
+	 * components to be run as non-root users. However, since the

+	 * configuration, this access needs to be protected in many
+	 * cases. By default, %wpa_supplicant is configured to use gid
+	 * 0 (root). If you want to allow non-root users to use the
+	 * control interface, add a new group and change this value to
+	 * match with that group. Add users that should have control
+	 * interface access to this group.

+	 * When configuring both the directory and group, use following format:
+	 * DIR=/var/run/wpa_supplicant GROUP=wheel

+	 * (ctrl_interface=udp).
+	 *
+	 * For Windows Named Pipe: This value can be used to set the security
+	 * descriptor for controlling access to the control interface. Security
+	 * descriptor can be set using Security Descriptor String Format (see
+	 * http://msdn.microsoft.com/library/default.asp?url=/library/en-us/secauthz/security/security_descriptor_string_format.asp).

+
+%wpa_supplicant implementation is divided into number of independent
+modules. Core code includes functionality for controlling the network
+selection, association, and configuration. Independent modules include
+WPA code (key handshake, PMKSA caching, pre-authentication), EAPOL
+state machine, and EAP state machine and methods. In addition, there
+are number of separate files for generic helper functions.
+
+Both WPA and EAPOL/EAP state machines can be used separately in other
+programs than %wpa_supplicant. As an example, the included test
+programs eapol_test and preauth_test are using these modules.
+
+\ref driver_wrapper "Driver interface API" is defined in driver.h and
+all hardware/driver dependent functionality is implemented in
+driver_*.c.

+external programs to control the operations of the %wpa_supplicant
+daemon and to get status information and event notifications. There is
+a small C library, in a form of a single C file, wpa_ctrl.c, that
+provides helper functions to facilitate the use of the control
+interface. External programs can link this file into them and then use
+the library functions documented in wpa_ctrl.h to interact with
+%wpa_supplicant. This library can also be used with C++. wpa_cli.c and
+wpa_gui are example programs using this library.
+
+There are multiple mechanisms for inter-process communication. For
+example, Linux version of %wpa_supplicant is using UNIX domain sockets
+for the control interface and Windows version UDP sockets. The use of
+the functions defined in wpa_ctrl.h can be used to hide the details of
+the used IPC from external programs.
+
+
+\section using_ctrl_iface Using the control interface
+
+External programs, e.g., a GUI or a configuration utility, that need to
+communicate with %wpa_supplicant should link in wpa_ctrl.c. This
+allows them to use helper functions to open connection to the control
+interface with wpa_ctrl_open() and to send commands with
+wpa_ctrl_request().
+
+%wpa_supplicant uses the control interface for two types of communication:
+commands and unsolicited event messages. Commands are a pair of
+messages, a request from the external program and a response from
+%wpa_supplicant. These can be executed using wpa_ctrl_request().
+Unsolicited event messages are sent by %wpa_supplicant to the control
+interface connection without specific request from the external program
+for receiving each message. However, the external program needs to
+attach to the control interface with wpa_ctrl_attach() to receive these
+unsolicited messages.
+
+If the control interface connection is used both for commands and
+unsolicited event messages, there is potential for receiving an
+unsolicited message between the command request and response.
+wpa_ctrl_request() caller will need to supply a callback, msg_cb,
+for processing these messages. Often it is easier to open two
+control interface connections by calling wpa_ctrl_open() twice and
+then use one of the connections for commands and the other one for
+unsolicited messages. This way command request/response pairs will
+not be broken by unsolicited messages. wpa_cli is an example of how
+to use only one connection for both purposes and wpa_gui demonstrates
+how to use two separate connections.
+
+Once the control interface connection is not needed anymore, it should
+be closed by calling wpa_ctrl_close(). If the connection was used for
+unsolicited event messages, it should be first detached by calling
+wpa_ctrl_detach().
+
+
+\section ctrl_iface_cmds Control interface commands
+
+Following commands can be used with wpa_ctrl_request():
+
+\subsection ctrl_iface_PING PING
+
+This command can be used to test whether %wpa_supplicant is replying
+to the control interface commands. The expected reply is \c PONG if the
+connection is open and %wpa_supplicant is processing commands.
+
+
+\subsection ctrl_iface_MIB MIB

+\c CTRL-RSP- (\a WPA_CTRL_RSP macro) prefix in a command with matching
+field name.
+
+The following fields can be requested in this way from the user:
+- IDENTITY (EAP identity/user name)
+- PASSWORD (EAP password)
+- NEW_PASSWORD (New password if the server is requesting password change)

+wpa_background \- Background information on Wi-Fi Protected Access and IEEE 802.11i
+.SH "WPA"
+.PP
+The original security mechanism of IEEE 802.11 standard was
+not designed to be strong and has proven to be insufficient for
+most networks that require some kind of security. Task group I
+(Security) of IEEE 802.11 working group
+(http://www.ieee802.org/11/) has worked to address the flaws of
+the base standard and has in practice completed its work in May
+2004. The IEEE 802.11i amendment to the IEEE 802.11 standard was
+approved in June 2004 and published in July 2004.
+.PP
+Wi-Fi Alliance (http://www.wi-fi.org/) used a draft version
+of the IEEE 802.11i work (draft 3.0) to define a subset of the
+security enhancements that can be implemented with existing wlan
+hardware. This is called Wi-Fi Protected Access<TM> (WPA). This
+has now become a mandatory component of interoperability testing
+and certification done by Wi-Fi Alliance. Wi-Fi provides
+information about WPA at its web site
+(http://www.wi-fi.org/OpenSection/protected_access.asp).
+.PP
+IEEE 802.11 standard defined wired equivalent privacy (WEP)
+algorithm for protecting wireless networks. WEP uses RC4 with
+40-bit keys, 24-bit initialization vector (IV), and CRC32 to
+protect against packet forgery. All these choices have proven to
+be insufficient: key space is too small against current attacks,
+RC4 key scheduling is insufficient (beginning of the pseudorandom
+stream should be skipped), IV space is too small and IV reuse
+makes attacks easier, there is no replay protection, and non-keyed
+authentication does not protect against bit flipping packet
+data.
+.PP
+WPA is an intermediate solution for the security issues. It
+uses Temporal Key Integrity Protocol (TKIP) to replace WEP. TKIP
+is a compromise on strong security and possibility to use existing
+hardware. It still uses RC4 for the encryption like WEP, but with
+per-packet RC4 keys. In addition, it implements replay protection,
+keyed packet authentication mechanism (Michael MIC).
+.PP
+Keys can be managed using two different mechanisms. WPA can
+either use an external authentication server (e.g., RADIUS) and
+EAP just like IEEE 802.1X is using or pre-shared keys without need
+for additional servers. Wi-Fi calls these "WPA-Enterprise" and
+"WPA-Personal", respectively. Both mechanisms will generate a
+master session key for the Authenticator (AP) and Supplicant
+(client station).
+.PP
+WPA implements a new key handshake (4-Way Handshake and
+Group Key Handshake) for generating and exchanging data encryption
+keys between the Authenticator and Supplicant. This handshake is
+also used to verify that both Authenticator and Supplicant know
+the master session key. These handshakes are identical regardless
+of the selected key management mechanism (only the method for
+generating master session key changes).
+.SH "IEEE 802.11I / WPA2"
+.PP
+The design for parts of IEEE 802.11i that were not included
+in WPA has finished (May 2004) and this amendment to IEEE 802.11
+was approved in June 2004. Wi-Fi Alliance is using the final IEEE
+802.11i as a new version of WPA called WPA2. This includes, e.g.,
+support for more robust encryption algorithm (CCMP: AES in Counter
+mode with CBC-MAC) to replace TKIP and optimizations for handoff
+(reduced number of messages in initial key handshake,
+pre-authentication, and PMKSA caching).

+.SH NAME
+wpa_cli \- WPA command line client
+.SH SYNOPSIS
+
+\fBwpa_cli\fR [ \fB-p \fIpath to ctrl sockets\fB\fR ] [ \fB-i \fIifname\fB\fR ] [ \fB-hvB\fR ] [ \fB-a \fIaction file\fB\fR ] [ \fB-P \fIpid file\fB\fR ] [ \fB\fIcommand ...\fB\fR ]
+
+.SH "OVERVIEW"
+.PP
+wpa_cli is a text-based frontend program for interacting
+with wpa_supplicant. It is used to query current status, change
+configuration, trigger events, and request interactive user
+input.
+.PP
+wpa_cli can show the current authentication status, selected
+security mode, dot11 and dot1x MIBs, etc. In addition, it can
+configure some variables like EAPOL state machine parameters and
+trigger events like reassociation and IEEE 802.1X
+logoff/logon. wpa_cli provides a user interface to request
+authentication information, like username and password, if these
+are not included in the configuration. This can be used to
+implement, e.g., one-time-passwords or generic token card
+authentication where the authentication is based on a
+challenge-response that uses an external device for generating the
+response.
+.PP
+The control interface of wpa_supplicant can be configured to
+allow non-root user access (ctrl_interface GROUP= parameter in the
+configuration file). This makes it possible to run wpa_cli with a
+normal user account.
+.PP
+wpa_cli supports two modes: interactive and command
+line. Both modes share the same command set and the main
+difference is in interactive mode providing access to unsolicited
+messages (event messages, username/password requests).
+.PP
+Interactive mode is started when wpa_cli is executed without
+including the command as a command line parameter. Commands are
+then entered on the wpa_cli prompt. In command line mode, the same
+commands are entered as command line arguments for wpa_cli.
+.SH "INTERACTIVE AUTHENTICATION PARAMETERS REQUEST"
+.PP
+When wpa_supplicant need authentication parameters, like
+username and password, which are not present in the configuration
+file, it sends a request message to all attached frontend programs,
+e.g., wpa_cli in interactive mode. wpa_cli shows these requests
+with "CTRL-REQ-<type>-<id>:<text>"
+prefix. <type> is IDENTITY, PASSWORD, or OTP
+(one-time-password). <id> is a unique identifier for the
+current network. <text> is description of the request. In
+case of OTP request, it includes the challenge from the
+authentication server.
+.PP
+The reply to these requests can be given with
+\fBidentity\fR, \fBpassword\fR, and
+\fBotp\fR commands. <id> needs to be copied from
+the matching request. \fBpassword\fR and
+\fBotp\fR commands can be used regardless of whether
+the request was for PASSWORD or OTP. The main difference between these
+two commands is that values given with \fBpassword\fR are
+remembered as long as wpa_supplicant is running whereas values given
+with \fBotp\fR are used only once and then forgotten,
+i.e., wpa_supplicant will ask frontend for a new value for every use.
+This can be used to implement one-time-password lists and generic token
+card -based authentication.
+.PP
+Example request for password and a matching reply:
+.sp
+.RS
+
+.nf
+CTRL-REQ-PASSWORD-1:Password needed for SSID foobar
+> password 1 mysecretpassword
+.fi
+.RE
+.PP
+Example request for generic token card challenge-response:

+the interface.
+

+.TH "WPA_PRIV" "8" "15 February 2009" "" ""
+
+.SH NAME
+wpa_priv \- wpa_supplicant privilege separation helper
+.SH SYNOPSIS
+
+\fBwpa_priv\fR [ \fB-c \fIctrl path\fB\fR ] [ \fB-Bdd\fR ] [ \fB-P \fIpid file\fB\fR ] [ \fBdriver:ifname \fI[driver:ifname ...]\fB\fR ]
+
+.SH "OVERVIEW"
+.PP
+\fBwpa_priv\fR is a privilege separation helper that
+minimizes the size of \fBwpa_supplicant\fR code that needs
+to be run with root privileges.
+.PP
+If enabled, privileged operations are done in the wpa_priv process
+while leaving rest of the code (e.g., EAP authentication and WPA
+handshakes) to operate in an unprivileged process (wpa_supplicant) that
+can be run as non-root user. Privilege separation restricts the effects
+of potential software errors by containing the majority of the code in an
+unprivileged process to avoid the possibility of a full system
+compromise.
+.PP
+\fBwpa_priv\fR needs to be run with network admin
+privileges (usually, root user). It opens a UNIX domain socket for each
+interface that is included on the command line; any other interface will
+be off limits for \fBwpa_supplicant\fR in this kind of
+configuration. After this, \fBwpa_supplicant\fR can be run as
+a non-root user (e.g., all standard users on a laptop or as a special
+non-privileged user account created just for this purpose to limit access
+to user files even further).
+.SH "EXAMPLE CONFIGURATION"
+.PP
+The following steps are an example of how to configure
+\fBwpa_priv\fR to allow users in the
+\fBwpapriv\fR group to communicate with
+\fBwpa_supplicant\fR with privilege separation:
+.PP
+Create user group (e.g., wpapriv) and assign users that
+should be able to use wpa_supplicant into that group.
+.PP
+Create /var/run/wpa_priv directory for UNIX domain sockets and
+control user access by setting it accessible only for the wpapriv
+group:
+.sp
+.RS
+
+.nf
+mkdir /var/run/wpa_priv
+chown root:wpapriv /var/run/wpa_priv
+chmod 0750 /var/run/wpa_priv
+.fi
+.RE
+.PP
+Start \fBwpa_priv\fR as root (e.g., from system
+startup scripts) with the enabled interfaces configured on the
+command line:
+.sp
+.RS
+
+.nf
+wpa_priv -B -c /var/run/wpa_priv -P /var/run/wpa_priv.pid wext:wlan0
+.fi
+.RE
+.PP
+Run \fBwpa_supplicant\fR as non-root with a user
+that is in the wpapriv group:
+.sp
+.RS
+
+.nf
+wpa_supplicant -i ath0 -c wpa_supplicant.conf
+.fi
+.RE
+.SH "COMMAND ARGUMENTS"
+.TP
+\fB-c ctrl path\fR
+Specify the path to wpa_priv control directory
+(Default: /var/run/wpa_priv/).
+.TP
+\fB-B\fR
+Run as a daemon in the background.
+.TP
+\fB-P file\fR
+Set the location of the PID
+file.
+.TP
+\fBdriver:ifname [driver:ifname ...]\fR
+The <driver> string dictates which of the
+supported \fBwpa_supplicant\fR driver backends is to be
+used. To get a list of supported driver types see wpa_supplicant help
+(e.g, wpa_supplicant -h). The driver backend supported by most good
+drivers is \fBwext\fR\&.
+
+The <ifname> string specifies which network
+interface is to be managed by \fBwpa_supplicant\fR
+(e.g., wlan0 or ath0).
+
+\fBwpa_priv\fR does not use the network interface
+before \fBwpa_supplicant\fR is started, so it is fine to
+include network interfaces that are not available at the time wpa_priv
+is started. wpa_priv can control multiple interfaces with one process,
+but it is also possible to run multiple \fBwpa_priv\fR
+processes at the same time, if desired.

+.SH NAME
+wpa_supplicant \- Wi-Fi Protected Access client and IEEE 802.1X supplicant
+.SH SYNOPSIS
+
+\fBwpa_supplicant\fR [ \fB-BddfhKLqqtuvW\fR ] [ \fB-i\fIifname\fB\fR ] [ \fB-c\fIconfig file\fB\fR ] [ \fB-D\fIdriver\fB\fR ] [ \fB-P\fIPID_file\fB\fR ] [ \fB-f\fIoutput file\fB\fR ]
+
+.SH "OVERVIEW"
+.PP
+Wireless networks do not require physical access to the network equipment
+in the same way as wired networks. This makes it easier for unauthorized
+users to passively monitor a network and capture all transmitted frames.
+In addition, unauthorized use of the network is much easier. In many cases,
+this can happen even without user's explicit knowledge since the wireless
+LAN adapter may have been configured to automatically join any available
+network.
+.PP
+Link-layer encryption can be used to provide a layer of security for
+wireless networks. The original wireless LAN standard, IEEE 802.11,
+included a simple encryption mechanism, WEP. However, that proved to
+be flawed in many areas and network protected with WEP cannot be consider
+secure. IEEE 802.1X authentication and frequently changed dynamic WEP keys
+can be used to improve the network security, but even that has inherited
+security issues due to the use of WEP for encryption. Wi-Fi Protected
+Access and IEEE 802.11i amendment to the wireless LAN standard introduce
+a much improvement mechanism for securing wireless networks. IEEE 802.11i
+enabled networks that are using CCMP (encryption mechanism based on strong
+cryptographic algorithm AES) can finally be called secure used for
+applications which require efficient protection against unauthorized
+access.
+.PP
+\fBwpa_supplicant\fR is an implementation of
+the WPA Supplicant component, i.e., the part that runs in the
+client stations. It implements WPA key negotiation with a WPA
+Authenticator and EAP authentication with Authentication
+Server. In addition, it controls the roaming and IEEE 802.11
+authentication/association of the wireless LAN driver.
+.PP
+\fBwpa_supplicant\fR is designed to be a
+"daemon" program that runs in the background and acts as the
+backend component controlling the wireless
+connection. \fBwpa_supplicant\fR supports separate
+frontend programs and an example text-based frontend,
+\fBwpa_cli\fR, is included with
+wpa_supplicant.
+.PP
+Before wpa_supplicant can do its work, the network interface
+must be available.  That means that the physical device must be
+present and enabled, and the driver for the device must be
+loaded. The daemon will exit immediately if the device is not already
+available.
+.PP
+After \fBwpa_supplicant\fR has configured the
+network device, higher level configuration such as DHCP may
+proceed.  There are a variety of ways to integrate wpa_supplicant
+into a machine's networking scripts, a few of which are described
+in sections below.
+.PP
+The following steps are used when associating with an AP
+using WPA:

+\fBwpa_supplicant\fR requests the kernel
+driver to scan neighboring BSSes
+.TP 0.2i

+.SH "OVERVIEW"
+.PP
+\fBwpa_supplicant\fR is configured using a text
+file that lists all accepted networks and security policies,
+including pre-shared keys. See the example configuration file,
+probably in \fB/usr/share/doc/wpa_supplicant/\fR, for
+detailed information about the configuration format and supported
+fields.
+.PP
+All file paths in this configuration file should use full
+(absolute, not relative to working directory) path in order to allow
+working directory to be changed. This can happen if wpa_supplicant is
+run in the background.
+.PP
+Changes to configuration file can be reloaded be sending
+SIGHUP signal to \fBwpa_supplicant\fR ('killall -HUP
+wpa_supplicant'). Similarly, reloading can be triggered with
+the \fBwpa_cli reconfigure\fR command.
+.PP
+Configuration file can include one or more network blocks,
+e.g., one for each used SSID. wpa_supplicant will automatically
+select the best network based on the order of network blocks in
+the configuration file, network security level (WPA/WPA2 is
+preferred), and signal strength.

+.SH "CERTIFICATES"
+.PP
+Some EAP authentication methods require use of
+certificates. EAP-TLS uses both server side and client
+certificates whereas EAP-PEAP and EAP-TTLS only require the server
+side certificate. When client certificate is used, a matching
+private key file has to also be included in configuration. If the
+private key uses a passphrase, this has to be configured in
+wpa_supplicant.conf ("private_key_passwd").
+.PP
+wpa_supplicant supports X.509 certificates in PEM and DER
+formats. User certificate and private key can be included in the
+same file.
+.PP
+If the user certificate and private key is received in
+PKCS#12/PFX format, they need to be converted to suitable PEM/DER
+format for wpa_supplicant. This can be done, e.g., with following
+commands:
+.sp
+.RS
+
+.nf
+# convert client certificate and private key to PEM format
+openssl pkcs12 -in example.pfx -out user.pem -clcerts

+    <para>
+    Wireless networks do not require physical access to the network equipment
+    in the same way as wired networks. This makes it easier for unauthorized
+    users to passively monitor a network and capture all transmitted frames.
+    In addition, unauthorized use of the network is much easier. In many cases,
+    this can happen even without user's explicit knowledge since the wireless
+    LAN adapter may have been configured to automatically join any available
+    network.
+    </para>
+
+    <para>
+    Link-layer encryption can be used to provide a layer of security for
+    wireless networks. The original wireless LAN standard, IEEE 802.11,
+    included a simple encryption mechanism, WEP. However, that proved to
+    be flawed in many areas and network protected with WEP cannot be consider
+    secure. IEEE 802.1X authentication and frequently changed dynamic WEP keys
+    can be used to improve the network security, but even that has inherited
+    security issues due to the use of WEP for encryption. Wi-Fi Protected
+    Access and IEEE 802.11i amendment to the wireless LAN standard introduce
+    a much improvement mechanism for securing wireless networks. IEEE 802.11i
+    enabled networks that are using CCMP (encryption mechanism based on strong
+    cryptographic algorithm AES) can finally be called secure used for
+    applications which require efficient protection against unauthorized
+    access.

+
+    <para><command>wpa_supplicant</command> is an implementation of
+    the WPA Supplicant component, i.e., the part that runs in the
+    client stations. It implements WPA key negotiation with a WPA
+    Authenticator and EAP authentication with Authentication
+    Server. In addition, it controls the roaming and IEEE 802.11
+    authentication/association of the wireless LAN driver.</para>
+
+    <para><command>wpa_supplicant</command> is designed to be a

+    must be available.  That means that the physical device must be

+    loaded. The daemon will exit immediately if the device is not already
+    available.</para>

+	(http://www.linksys.com/support/gpl.asp) for Linksys
+	WRT54G. The GPL tarball includes cross-compiler and the needed

+    <para>wpa_supplicant was designed to be portable for different
+    drivers and operating systems. Hopefully, support for more wlan
+    cards and OSes will be added in the future. See developer.txt for
+    more information about the design of wpa_supplicant and porting to
+    other drivers. One main goal is to add full WPA/WPA2 support to
+    Linux wireless extensions to allow new drivers to be supported
+    without having to implement new driver-specific interface code in
+    wpa_supplicant.</para>

+  </refsect1>
+
+  <refsect1>
+    <title>Quick Start</title>
+
+    <para>First, make a configuration file, e.g.
+    <filename>/etc/wpa_supplicant.conf</filename>, that describes the networks
+    you are interested in.  See <citerefentry>
+	<refentrytitle>wpa_supplicant.conf</refentrytitle>
+	<manvolnum>5</manvolnum>
+      </citerefentry>
+    for details.</para>
+
+    <para>Once the configuration is ready, you can test whether the
+    configuration works by running <command>wpa_supplicant</command>
+    with following command to start it on foreground with debugging
+    enabled:</para>
+
+    <blockquote><programlisting>
+wpa_supplicant -iwlan0 -c/etc/wpa_supplicant.conf -d
+    </programlisting></blockquote>
+
+    <para>Assuming everything goes fine, you can start using following
+    command to start <command>wpa_supplicant</command> on background
+    without debugging:</para>
+
+    <blockquote><programlisting>
+wpa_supplicant -iwlan0 -c/etc/wpa_supplicant.conf -B
+    </programlisting></blockquote>
+
+    <para>Please note that if you included more than one driver
+    interface in the build time configuration (.config), you may need
+    to specify which interface to use by including -D&lt;driver
+    name&gt; option on the command line.</para>
+
+    <!-- XXX at this point, the page could include a little script
+         based on wpa_cli to wait for a connection and then run
+         dhclient -->
+
+  </refsect1>
+
+  <refsect1>
+    <title>Interface to pcmcia-cs/cardmrg</title>
+
+    <para>For example, following small changes to pcmcia-cs scripts
+    can be used to enable WPA support:</para>
+
+    <para>Add MODE="Managed" and WPA="y" to the network scheme in
+    <filename>/etc/pcmcia/wireless.opts</filename>.</para>
+
+    <para>Add the following block to the end of <emphasis>start</emphasis>
+    action handler in <filename>/etc/pcmcia/wireless</filename>:</para>
+
+    <blockquote><programlisting>
+if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
+    /usr/local/bin/wpa_supplicant -B -c/etc/wpa_supplicant.conf -i$DEVICE
+fi
+    </programlisting></blockquote>
+
+
+    <para>Add the following block to the end of <emphasis>stop</emphasis>
+    action handler (may need to be separated from other actions) in
+    <filename>/etc/pcmcia/wireless</filename>:</para>
+
+    <blockquote><programlisting>
+if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
+    killall wpa_supplicant
+fi
+    </programlisting></blockquote>
+
+    <para>This will make <command>cardmgr</command> start

+/**
+\page driver_wrapper Driver wrapper implementation (driver.h, drivers.c)
+
+All hardware and driver dependent functionality is in separate C files
+that implement defined wrapper functions. Other parts
+of the %wpa_supplicant are designed to be hardware, driver, and operating
+system independent.
+
+Driver wrappers need to implement whatever calls are used in the
+target operating system/driver for controlling wireless LAN
+devices. As an example, in case of Linux, these are mostly some glue
+code and ioctl() calls and netlink message parsing for Linux Wireless
+Extensions (WE). Since features required for WPA were added only recently to
+Linux Wireless Extensions (in version 18), some driver specific code is used
+in number of driver interface implementations. These driver dependent parts
+can be replaced with generic code in driver_wext.c once the target driver
+includes full support for WE-18. After that, all Linux drivers, at
+least in theory, could use the same driver wrapper code.
+
+A driver wrapper needs to implement some or all of the functions
+defined in driver.h. These functions are registered by filling struct
+wpa_driver_ops with function pointers. Hardware independent parts of
+%wpa_supplicant will call these functions to control the driver/wlan
+card. In addition, support for driver events is required. The event
+callback function, wpa_supplicant_event(), and its parameters are
+documented in driver.h. In addition, a pointer to the 'struct
+wpa_driver_ops' needs to be registered in drivers.c file.
+
+When porting to other operating systems, the driver wrapper should be
+modified to use the native interface of the target OS. It is possible
+that some extra requirements for the interface between the driver
+wrapper and generic %wpa_supplicant code are discovered during porting
+to a new operating system. These will be addressed on case by case
+basis by modifying the interface and updating the other driver
+wrappers for this. The goal is to avoid changing this interface
+without very good reasons in order to limit the number of changes
+needed to other wrappers and hardware independent parts of
+%wpa_supplicant. When changes are required, recommended way is to
+make them in backwards compatible way that allows existing driver
+interface implementations to be compiled without any modification.
+
+Generic Linux Wireless Extensions functions are implemented in
+driver_wext.c. All Linux driver wrappers can use these when the kernel
+driver supports the generic ioctl()s and wireless events. Driver
+specific functions are implemented in separate C files, e.g.,
+driver_hostap.c. These files need to define struct wpa_driver_ops
+entry that will be used in wpa_supplicant.c when calling driver
+functions. struct wpa_driver_ops entries are registered in drivers.c.
+
+In general, it is likely to be useful to first take a look at couple
+of driver interface examples before starting on implementing a new
+one. driver_hostap.c and driver_wext.c include a complete
+implementation for Linux drivers that use %wpa_supplicant-based control
+of WPA IE and roaming. driver_ndis.c (with help from driver_ndis_.c)
+is an example of a complete interface for Windows NDIS interface for
+drivers that generate WPA IE themselves and decide when to roam. These
+example implementations include full support for all security modes.
+
+
+\section driver_req Driver requirements for WPA
+
+WPA introduces new requirements for the device driver. At least some
+of these need to be implemented in order to provide enough support for
+%wpa_supplicant.
+
+\subsection driver_tkip_ccmp TKIP/CCMP
+
+WPA requires that the pairwise cipher suite (encryption algorithm for
+unicast data packets) is TKIP or CCMP. These are new encryption
+protocols and thus, the driver will need to be modified to support
+them. Depending on the used wlan hardware, some parts of these may be
+implemented by the hardware/firmware.
+
+Specification for both TKIP and CCMP is available from IEEE (IEEE
+802.11i amendment). Fully functional, hardware independent
+implementation of both encryption protocols is also available in Host
+AP driver (driver/modules/hostap_{tkip,ccmp}.c). In addition, Linux 2.6
+kernel tree has generic implementations for WEP, TKIP, and CCMP that can
+be used in Linux drivers.
+
+The driver will also need to provide configuration mechanism to allow
+user space programs to configure TKIP and CCMP. Linux Wireless Extensions
+v18 added support for configuring these algorithms and
+individual/non-default keys. If the target kernel does not include WE-18,
+private ioctls can be used to provide similar functionality.
+
+\subsection driver_roaming Roaming control and scanning support
+
+%wpa_supplicant can optionally control AP selection based on the
+information received from Beacon and/or Probe Response frames
+(ap_scan=1 mode in configuration). This means that the driver should
+support external control for scan process. In case of Linux, use of
+new Wireless Extensions scan support (i.e., 'iwlist wlan0 scan') is
+recommended. The current driver wrapper (driver_wext.c) uses this for
+scan results.
+
+Scan results must also include the WPA information element. Support for
+this was added in WE-18. With older versions, a custom event can be used
+to provide the full WPA IE (including element id and length) as a hex
+string that is included in the scan results.
+
+%wpa_supplicant needs to also be able to request the driver to
+associate with a specific BSS. Current Host AP driver and matching
+driver_hostap.c wrapper uses following sequence for this
+request. Similar/identical mechanism should be usable also with other
+drivers.
+
+- set WPA IE for AssocReq with private ioctl
+- set SSID with SIOCSIWESSID
+- set channel/frequency with SIOCSIWFREQ
+- set BSSID with SIOCSIWAP
+  (this last ioctl will trigger the driver to request association)
+
+\subsection driver_wpa_ie WPA IE generation
+
+%wpa_supplicant selects which cipher suites and key management suites
+are used. Based on this information, it generates a WPA IE. This is
+provided to the driver interface in the associate call. This does not
+match with Windows NDIS drivers which generate the WPA IE
+themselves.
+
+%wpa_supplicant allows Windows NDIS-like behavior by providing the
+selected cipher and key management suites in the associate call. If
+the driver generates its own WPA IE and that differs from the one
+generated by %wpa_supplicant, the driver has to inform %wpa_supplicant
+about the used WPA IE (i.e., the one it used in (Re)Associate
+Request). This notification is done using EVENT_ASSOCINFO event (see
+driver.h). %wpa_supplicant is normally configured to use
+ap_scan=2 mode with drivers that control WPA IE generation and roaming.
+
+\subsection driver_events Driver events
+
+%wpa_supplicant needs to receive event callbacks when certain events
+occur (association, disassociation, Michael MIC failure, scan results
+available, PMKSA caching candidate). These events and the callback
+details are defined in driver.h (wpa_supplicant_event() function
+and enum wpa_event_type).
+
+On Linux, association and disassociation can use existing Wireless
+Extensions event that is reporting new AP with SIOCGIWAP
+event. Similarly, completion of a scan can be reported with SIOCGIWSCAN
+event.
+
+Michael MIC failure event was added in WE-18. Older versions of Wireless
+Extensions will need to use a custom event. Host AP driver used a custom
+event with following contents: MLME-MICHAELMICFAILURE.indication(keyid=#
+broadcast/unicast addr=addr2). This is the recommended format until
+the driver can be moved to use WE-18 mechanism.
+
+\subsection driver_wext_summary Summary of Linux Wireless Extensions use
+
+AP selection depends on ap_scan configuration:
+
+ap_scan=1:
+
+- %wpa_supplicant requests scan with SIOCSIWSCAN
+- driver reports scan complete with wireless event SIOCGIWSCAN
+- %wpa_supplicant reads scan results with SIOCGIWSCAN (multiple call if
+  a larget buffer is needed)
+- %wpa_supplicant decides which AP to use based on scan results
+- %wpa_supplicant configures driver to associate with the selected BSS
+  (SIOCSIWMODE, SIOCSIWGENIE, SIOCSIWAUTH, SIOCSIWFREQ,
+   SIOCSIWESSID, SIOCSIWAP)
+
+ap_scan=2:
+
+- %wpa_supplicant configures driver to associate with an SSID
+  (SIOCSIWMODE, SIOCSIWGENIE, SIOCSIWAUTH, SIOCSIWESSID)
+
+
+After this, both modes use similar steps:
+
+- optionally (or required for drivers that generate WPA/RSN IE for
+  (Re)AssocReq), driver reports association parameters (AssocReq IEs)
+  with wireless event IWEVASSOCREQIE (and optionally IWEVASSOCRESPIE)
+- driver reports association with wireless event SIOCGIWAP
+- %wpa_supplicant takes care of EAPOL frame handling (validating
+  information from associnfo and if needed, from scan results if WPA/RSN
+  IE from the Beacon frame is not reported through associnfo)

+/**
+\page eap_module EAP peer implementation
+
+Extensible Authentication Protocol (EAP) is an authentication framework
+defined in RFC 3748. %wpa_supplicant uses a separate code module for EAP
+peer implementation. This module was designed to use only a minimal set
+of direct function calls (mainly, to debug/event functions) in order for
+it to be usable in other programs. The design of the EAP
+implementation is based loosely on RFC 4137. The state machine is
+defined in this RFC and so is the interface between the peer state
+machine and methods. As such, this RFC provides useful information for
+understanding the EAP peer implementation in %wpa_supplicant.
+
+Some of the terminology used in EAP state machine is referring to
+EAPOL (IEEE 802.1X), but there is no strict requirement on the lower
+layer being IEEE 802.1X if EAP module is built for other programs than
+%wpa_supplicant. These terms should be understood to refer to the
+lower layer as defined in RFC 4137.
+
+
+\section adding_eap_methods Adding EAP methods
+
+Each EAP method is implemented as a separate module, usually as one C
+file named eap_<name of the method>.c, e.g., eap_md5.c. All EAP
+methods use the same interface between the peer state machine and
+method specific functions. This allows new EAP methods to be added
+without modifying the core EAP state machine implementation.
+
+New EAP methods need to be registered by adding them into the build
+(Makefile) and the EAP method registration list in the
+eap_peer_register_methods() function of eap_methods.c. Each EAP
+method should use a build-time configuration option, e.g., EAP_TLS, in
+order to make it possible to select which of the methods are included
+in the build.
+
+EAP methods must implement the interface defined in eap_i.h. struct
+eap_method defines the needed function pointers that each EAP method
+must provide. In addition, the EAP type and name are registered using
+this structure. This interface is based on section 4.4 of RFC 4137.
+
+It is recommended that the EAP methods would use generic helper
+functions, eap_msg_alloc() and eap_hdr_validate() when processing
+messages. This allows code sharing and can avoid missing some of the
+needed validation steps for received packets. In addition, these
+functions make it easier to change between expanded and legacy EAP
+header, if needed.
+
+When adding an EAP method that uses a vendor specific EAP type
+(Expanded Type as defined in RFC 3748, Chapter 5.7), the new method
+must be registered by passing vendor id instead of EAP_VENDOR_IETF to
+eap_peer_method_alloc(). These methods must not try to emulate
+expanded types by registering a legacy EAP method for type 254. See
+eap_vendor_test.c for an example of an EAP method implementation that
+is implemented as an expanded type.
+
+
+\section used_eap_library Using EAP implementation as a library
+
+The Git repository has an eap_example directory that contains an
+example showing how EAP peer and server code from %wpa_supplicant and
+hostapd can be used as a library. The example program initializes both
+an EAP server and an EAP peer entities and then runs through an
+EAP-PEAP/MSCHAPv2 authentication.
+
+eap_example_peer.c shows the initialization and glue code needed to
+control the EAP peer implementation. eap_example_server.c does the
+same for EAP server. eap_example.c is an example that ties in both the
+EAP server and client parts to allow an EAP authentication to be
+shown.
+
+In this example, the EAP messages are passed between the server and
+the peer are passed by direct function calls within the same process.
+In practice, server and peer functionalities would likely reside in
+separate devices and the EAP messages would be transmitted between the
+devices based on an external protocol. For example, in IEEE 802.11
+uses IEEE 802.1X EAPOL state machines to control the transmission of
+EAP messages and WiMax supports optional PMK EAP authentication
+mechanism that transmits EAP messages as defined in IEEE 802.16e.
+
+The EAP library links in number of helper functions from src/utils and
+src/crypto directories. Most of these are suitable as-is, but it may
+be desirable to replace the debug output code in src/utils/wpa_debug.c
+by dropping this file from the library and re-implementing the
+functions there in a way that better fits in with the main
+application.

+\mainpage Developers' documentation for wpa_supplicant
+
+%wpa_supplicant is a WPA Supplicant for Linux, BSD and Windows with
+support for WPA and WPA2 (IEEE 802.11i / RSN). Supplicant is the IEEE
+802.1X/WPA component that is used in the client stations. It
+implements key negotiation with a WPA Authenticator and it can optionally
+control roaming and IEEE 802.11 authentication/association of the wlan
+driver.
+
+The goal of this documentation and comments in the source code is to
+give enough information for other developers to understand how
+%wpa_supplicant has been implemented, how it can be modified, how new
+drivers can be supported, and how %wpa_supplicant can be ported to
+other operating systems. If any information is missing, feel free to
+contact Jouni Malinen <j@w1.fi> for more
+information. Contributions as patch files are also very welcome at the
+same address. Please note that %wpa_supplicant is licensed under dual
+license, GPLv2 or BSD at user's choice. All contributions to
+%wpa_supplicant are expected to use compatible licensing terms.
+
+The source code and read-only access to %wpa_supplicant Git repository
+is available from the project home page at
+http://w1.fi/wpa_supplicant/. This developers' documentation
+is also available as a PDF file from
+http://w1.fi/wpa_supplicant/wpa_supplicant-devel.pdf .
+
+The design goal for %wpa_supplicant was to use hardware, driver, and
+OS independent, portable C code for all WPA functionality. The source
+code is divided into separate C files as shown on the \ref
+code_structure "code structure page". All hardware/driver specific
+functionality is in separate files that implement a \ref
+driver_wrapper "well-defined driver API". Information about porting
+to different target boards and operating systems is available on
+the \ref porting "porting page".
+
+EAPOL (IEEE 802.1X) state machines are implemented as a separate
+module that interacts with \ref eap_module "EAP peer implementation".
+In addition to programs aimed at normal production use,
+%wpa_supplicant source tree includes number of \ref testing_tools
+"testing and development tools" that make it easier to test the
+programs without having to setup a full test setup with wireless
+cards. These tools can also be used to implement automatic test
+suites.
+
+%wpa_supplicant implements a
+\ref ctrl_iface_page "control interface" that can be used by
+external programs to control the operations of the %wpa_supplicant
+daemon and to get status information and event notifications. There is
+a small C library that provides helper functions to facilitate the use of the
+control interface. This library can also be used with C++.

+/**
+\page porting Porting to different target boards and operating systems
+
+%wpa_supplicant was designed to be easily portable to different
+hardware (board, CPU) and software (OS, drivers) targets. It is
+already used with number of operating systems and numerous wireless
+card models and drivers. The main %wpa_supplicant repository includes
+support for Linux, FreeBSD, and Windows. In addition, at least VxWorks,
+PalmOS, Windows CE, and Windows Mobile are supported in separate
+repositories. On the hardware
+side, %wpa_supplicant is used on various systems: desktops, laptops,
+PDAs, and embedded devices with CPUs including x86, PowerPC,
+arm/xscale, and MIPS. Both big and little endian configurations are
+supported.
+
+
+\section ansi_c_extra Extra functions on top of ANSI C
+
+%wpa_supplicant is mostly using ANSI C functions that are available on
+most targets. However, couple of additional functions that are common
+on modern UNIX systems are used. Number of these are listed with
+prototypes in common.h (the \verbatim #ifdef CONFIG_ANSI_C_EXTRA \endverbatim
+block). These functions may need to be implemented or at least defined
+as macros to native functions in the target OS or C library.
+
+Many of the common ANSI C functions are used through a wrapper
+definitions in os.h to allow these to be replaced easily with a
+platform specific version in case standard C libraries are not
+available. In addition, os.h defines couple of common platform
+specific functions that are implemented in os_unix.c for UNIX like
+targets and in os_win32.c for Win32 API. If the target platform does
+not support either of these examples, a new os_*.c file may need to be
+added.
+
+Unless OS_NO_C_LIB_DEFINES is defined, the standard ANSI C and POSIX
+functions are used by defining the os_*() wrappers to use them
+directly in order to avoid extra cost in size and speed. If the target
+platform needs different versions of the functions, os.h can be
+modified to define the suitable macros or alternatively,
+OS_NO_C_LIB_DEFINES may be defined for the build and the wrapper
+functions can then be implemented in a new os_*.c wrapper file.
+
+common.h defines number of helper macros for handling integers of
+different size and byte order. Suitable version of these definitions
+may need to be added for the target platform.
+
+
+\section configuration_backend Configuration backend
+
+%wpa_supplicant implements a configuration interface that allows the
+backend to be easily replaced in order to read configuration data from
+a suitable source depending on the target platform. config.c
+implements the generic code that can be shared with all configuration
+backends. Each backend is implemented in its own config_*.c file.
+
+The included config_file.c backend uses a text file for configuration
+and config_winreg.c uses Windows registry. These files can be used as
+an example for a new configuration backend if the target platform uses
+different mechanism for configuration parameters. In addition,
+config_none.c can be used as an empty starting point for building a
+new configuration backend.
+
+
+\section driver_iface_porting Driver interface
+
+Unless the target OS and driver is already supported, most porting
+projects have to implement a driver wrapper. This may be done by
+adding a new driver interface module or modifying an existing module
+(driver_*.c) if the new target is similar to one of them. \ref
+driver_wrapper "Driver wrapper implementation" describes the details
+of the driver interface and discusses the tasks involved in porting
+this part of %wpa_supplicant.
+
+
+\section l2_packet_porting l2_packet (link layer access)
+
+%wpa_supplicant needs to have access to sending and receiving layer 2
+(link layer) packets with two Ethertypes: EAP-over-LAN (EAPOL) 0x888e
+and RSN pre-authentication 0x88c7. l2_packet.h defines the interfaces
+used for this in the core %wpa_supplicant implementation.
+
+If the target operating system supports a generic mechanism for link
+layer access, that is likely the best mechanism for providing the
+needed functionality for %wpa_supplicant. Linux packet socket is an
+example of such a generic mechanism. If this is not available, a
+separate interface may need to be implemented to the network stack or
+driver. This is usually an intermediate or protocol driver that is
+operating between the device driver and the OS network stack. If such
+a mechanism is not feasible, the interface can also be implemented
+directly in the device driver.
+
+The main %wpa_supplicant repository includes l2_packet implementations
+for Linux using packet sockets (l2_packet_linux.c), more portable
+version using libpcap/libdnet libraries (l2_packet_pcap.c; this
+supports WinPcap, too), and FreeBSD specific version of libpcap
+interface (l2_packet_freebsd.c).
+
+If the target operating system is supported by libpcap (receiving) and
+libdnet (sending), l2_packet_pcap.c can likely be used with minimal or
+no changes. If this is not a case or a proprietary interface for link
+layer is required, a new l2_packet module may need to be
+added. Alternatively, struct wpa_driver_ops::send_eapol() handler can
+be used to override the l2_packet library if the link layer access is
+integrated with the driver interface implementation.
+
+
+\section eloop_porting Event loop
+
+%wpa_supplicant uses a single process/thread model and an event loop
+to provide callbacks on events (registered timeout, received packet,
+signal). eloop.h defines the event loop interface. eloop.c is an
+implementation of such an event loop using select() and sockets. This
+is suitable for most UNIX/POSIX systems. When porting to other
+operating systems, it may be necessary to replace that implementation
+with OS specific mechanisms that provide similar functionality.
+
+
+\section ctrl_iface_porting Control interface
+
+%wpa_supplicant uses a \ref ctrl_iface_page "control interface"
+to allow external processed
+to get status information and to control the operations. Currently,
+this is implemented with socket based communication; both UNIX domain
+sockets and UDP sockets are supported. If the target OS does not
+support sockets, this interface will likely need to be modified to use
+another mechanism like message queues. The control interface is
+optional component, so it is also possible to run %wpa_supplicant
+without porting this part.
+
+The %wpa_supplicant side of the control interface is implemented in
+ctrl_iface.c. Matching client side is implemented as a control
+interface library in wpa_ctrl.c.
+
+
+\section entry_point Program entry point
+
+%wpa_supplicant defines a set of functions that can be used to
+initialize main supplicant processing. Each operating system has a
+mechanism for starting new processing or threads. This is usually a
+function with a specific set of arguments and calling convention. This
+function is responsible on initializing %wpa_supplicant.
+
+main.c includes an entry point for UNIX-like operating system, i.e.,
+main() function that uses command line arguments for setting
+parameters for %wpa_supplicant. When porting to other operating
+systems, similar OS-specific entry point implementation is needed. It
+can be implemented in a new file that is then linked with
+%wpa_supplicant instead of main.o. main.c is also a good example on
+how the initialization process should be done.
+
+The supplicant initialization functions are defined in
+wpa_supplicant_i.h. In most cases, the entry point function should
+start by fetching configuration parameters. After this, a global
+%wpa_supplicant context is initialized with a call to
+wpa_supplicant_init(). After this, existing network interfaces can be
+added with wpa_supplicant_add_iface(). wpa_supplicant_run() is then
+used to start the main event loop. Once this returns at program
+termination time, wpa_supplicant_deinit() is used to release global
+context data.
+
+wpa_supplicant_add_iface() and wpa_supplicant_remove_iface() can be
+used dynamically to add and remove interfaces based on when
+%wpa_supplicant processing is needed for them. This can be done, e.g.,
+when hotplug network adapters are being inserted and ejected. It is
+also possible to do this when a network interface is being
+enabled/disabled if it is desirable that %wpa_supplicant processing
+for the interface is fully enabled/disabled at the same time.
+
+
+\section simple_build Simple build example
+
+One way to start a porting project is to begin with a very simple
+build of %wpa_supplicant with WPA-PSK support and once that is
+building correctly, start adding features.
+
+Following command can be used to build very simple version of
+%wpa_supplicant:
+
+\verbatim
+cc -o wpa_supplicant config.c eloop.c common.c md5.c rc4.c sha1.c \
+	config_none.c l2_packet_none.c tls_none.c wpa.c preauth.c \
+	aes_wrap.c wpa_supplicant.c events.c main_none.c drivers.c
+\endverbatim
+
+The end result is not really very useful since it uses empty functions
+for configuration parsing and layer 2 packet access and does not
+include a driver interface. However, this is a good starting point
+since the build is complete in the sense that all functions are
+present and this is easy to configure to a build system by just
+including the listed C files.
+
+Once this version can be build successfully, the end result can be
+made functional by adding a proper program entry point (main*.c),
+driver interface (driver_*.c and matching CONFIG_DRIVER_* define for
+registration in drivers.c), configuration parser/writer (config_*.c),
+and layer 2 packet access implementation (l2_packet_*.c). After these
+components have been added, the end result should be a working
+WPA/WPA2-PSK enabled supplicant.
+
+After the basic functionality has been verified to work, more features
+can be added by linking in more files and defining C pre-processor
+defines. Currently, the best source of information for what options
+are available and which files needs to be included is in the Makefile
+used for building the supplicant with make. Similar configuration will
+be needed for build systems that either use different type of make
+tool or a GUI-based project configuration.

+[ \ref eapol_test "eapol_test" |
+\ref preauth_test "preauth_test" |
+\ref driver_test "driver_test" |
+\ref unit_tests "Unit tests" ]
+
+%wpa_supplicant source tree includes number of testing and development
+tools that make it easier to test the programs without having to setup
+a full test setup with wireless cards. In addition, these tools can be
+used to implement automatic tests suites.
+
+\section eapol_test eapol_test - EAP peer and RADIUS client testing
+
+eapol_test is a program that links together the same EAP peer
+implementation that %wpa_supplicant is using and the RADIUS
+authentication client code from hostapd. In addition, it has minimal
+glue code to combine these two components in similar ways to IEEE
+802.1X/EAPOL Authenticator state machines. In other words, it
+integrates IEEE 802.1X Authenticator (normally, an access point) and
+IEEE 802.1X Supplicant (normally, a wireless client) together to
+generate a single program that can be used to test EAP methods without
+having to setup an access point and a wireless client.
+
+The main uses for eapol_test are in interoperability testing of EAP
+methods against RADIUS servers and in development testing for new EAP
+methods. It can be easily used to automate EAP testing for
+interoperability and regression since the program can be run from
+shell scripts without require additional test components apart from a
+RADIUS server. For example, the automated EAP tests described in
+eap_testing.txt are implemented with eapol_test. Similarly, eapol_test
+could be used to implement an automated regression test suite for a
+RADIUS authentication server.
+
+eapol_test uses the same build time configuration file, .config, as
+%wpa_supplicant. This file is used to select which EAP methods are
+included in eapol_test. This program is not built with the default
+Makefile target, so a separate make command needs to be used to
+compile the tool:
+
+\verbatim
+make eapol_test
+\endverbatim
+
+The resulting eapol_test binary has following command like options:
+
+\verbatim
+usage:
+eapol_test [-nWS] -c<conf> [-a<AS IP>] [-p<AS port>] [-s<AS secret>] \
+           [-r<count>] [-t<timeout>] [-C<Connect-Info>] \
+           [-M<client MAC address>]
+eapol_test scard
+eapol_test sim <PIN> <num triplets> [debug]
+
+options:
+  -c<conf> = configuration file
+  -a<AS IP> = IP address of the authentication server, default 127.0.0.1
+  -p<AS port> = UDP port of the authentication server, default 1812
+  -s<AS secret> = shared secret with the authentication server, default 'radius'
+  -r<count> = number of re-authentications
+  -W = wait for a control interface monitor before starting
+  -S = save configuration after authentiation
+  -n = no MPPE keys expected
+  -t<timeout> = sets timeout in seconds (default: 30 s)
+  -C<Connect-Info> = RADIUS Connect-Info (default: CONNECT 11Mbps 802.11b)
+  -M<client MAC address> = Set own MAC address (Calling-Station-Id,
+                           default: 02:00:00:00:00:01)
+\endverbatim
+
+
+As an example,
+\verbatim
+eapol_test -ctest.conf -a127.0.0.1 -p1812 -ssecret -r1
+\endverbatim
+tries to complete EAP authentication based on the network
+configuration from test.conf against the RADIUS server running on the
+local host. A re-authentication is triggered to test fast
+re-authentication. The configuration file uses the same format for
+network blocks as %wpa_supplicant.
+
+
+\section preauth_test preauth_test - WPA2 pre-authentication and EAP peer testing
+
+preauth_test is similar to eapol_test in the sense that in combines
+EAP peer implementation with something else, in this case, with WPA2
+pre-authentication. This tool can be used to test pre-authentication
+based on the code that %wpa_supplicant is using. As such, it tests
+both the %wpa_supplicant implementation and the functionality of an
+access point.
+
+preauth_test is built with:
+
+\verbatim
+make preauth_test
+\endverbatim
+
+and it uses following command line arguments:
+
+\verbatim
+usage: preauth_test <conf> <target MAC address> <ifname>
+\endverbatim
+
+For example,
+\verbatim
+preauth_test test.conf 02:11:22:33:44:55 eth0
+\endverbatim
+would use network configuration from test.conf to try to complete
+pre-authentication with AP using BSSID 02:11:22:33:44:55. The
+pre-authentication packets would be sent using the eth0 interface.
+
+
+\section driver_test driver_test - driver interface for testing wpa_supplicant
+
+%wpa_supplicant was designed to support number of different ways to
+communicate with a network device driver. This design uses \ref
+driver_wrapper "driver interface API" and number of driver interface
+implementations. One of these is driver_test.c, i.e., a test driver
+interface that is actually not using any drivers. Instead, it provides
+a mechanism for running %wpa_supplicant without having to have a
+device driver or wireless LAN hardware for that matter.
+
+driver_test can be used to talk directly with hostapd's driver_test
+component to create a test setup where one or more clients and access
+points can be tested within one test host and without having to have
+multiple wireless cards. This makes it easier to test the core code in
+%wpa_supplicant, and hostapd for that matter. Since driver_test uses
+the same driver API than any other driver interface implementation,
+the core code of %wpa_supplicant and hostapd can be tested with the
+same coverage as one would get when using real wireless cards. The
+only area that is not tested is the driver interface implementation
+(driver_*.c).
+
+Having the possibility to use simulated network components makes it
+much easier to do development testing while adding new features and to
+reproduce reported bugs. As such, it is often easiest to just do most
+of the development and bug fixing without using real hardware. Once
+the driver_test setup has been used to implement a new feature or fix
+a bug, the end result can be verified with wireless LAN cards. In many
+cases, this may even be unnecessary, depending on what area the
+feature/bug is relating to. Of course, changes to driver interfaces
+will still require use of real hardware.
+
+Since multiple components can be run within a single host, testing of
+complex network configuration, e.g., large number of clients
+association with an access point, becomes quite easy. All the tests
+can also be automated without having to resort to complex test setup
+using remote access to multiple computers.
+
+driver_test can be included in the %wpa_supplicant build in the same
+way as any other driver interface, i.e., by adding the following line
+into .config:
+
+\verbatim
+CONFIG_DRIVER_TEST=y
+\endverbatim
+
+When running %wpa_supplicant, the test interface is selected by using
+\a -Dtest command line argument. The interface name (\a -i argument)
+can be selected arbitrarily, i.e., it does not need to match with any
+existing network interface. The interface name is used to generate a
+MAC address, so when using multiple clients, each should use a
+different interface, e.g., \a sta1, \a sta2, and so on.
+
+%wpa_supplicant and hostapd are configured in the same way as they
+would be for normal use. Following example shows a simple test setup
+for WPA-PSK.
+
+hostapd is configured with following psk-test.conf configuration file:
+
+\verbatim
+driver=test
+
+interface=ap1
+logger_stdout=-1
+logger_stdout_level=0
+debug=2
+dump_file=/tmp/hostapd.dump
+
+test_socket=/tmp/Test/ap1
+
+ssid=jkm-test-psk
+
+wpa=1
+wpa_key_mgmt=WPA-PSK
+wpa_pairwise=TKIP
+wpa_passphrase=12345678
+\endverbatim
+
+and started with following command:

+
+%wpa_supplicant uses following configuration file:
+
+\verbatim
+driver_param=test_socket=/tmp/Test/ap1
+
+network={
+    ssid="jkm-test-psk"
+    key_mgmt=WPA-PSK
+    psk="12345678"
+}
+\endverbatim
+
+%wpa_supplicant can then be started with following command:
+
+\verbatim
+wpa_supplicant -Dtest -cpsk-test.conf -ista1 -ddK
+\endverbatim
+
+If run without debug information, i.e., with
+
+\verbatim
+wpa_supplicant -Dtest -cpsk-test.conf -ista1
+\endverbatim
+
+%wpa_supplicant completes authentication and prints following events:
+
+\verbatim
+Trying to associate with 02:b8:a6:62:08:5a (SSID='jkm-test-psk' freq=0 MHz)
+Associated with 02:b8:a6:62:08:5a
+WPA: Key negotiation completed with 02:b8:a6:62:08:5a [PTK=TKIP GTK=TKIP]
+CTRL-EVENT-CONNECTED - Connection to 02:b8:a6:62:08:5a completed (auth)
+\endverbatim
+
+If test setup is using multiple clients, it is possible to run
+multiple %wpa_supplicant processes. Alternatively, the support for
+multiple interfaces can be used with just one process to save some
+resources on single-CPU systems. For example, following command runs
+two clients:
+
+\verbatim
+./wpa_supplicant -Dtest -cpsk-test.conf -ista1 \
+	-N -Dtest -cpsk-test.conf -ista2
+\endverbatim
+
+This shows following event log:
+
+\verbatim
+Trying to associate with 02:b8:a6:62:08:5a (SSID='jkm-test-psk' freq=0 MHz)
+Associated with 02:b8:a6:62:08:5a

+\endverbatim
+
+hostapd shows this with following events:
+
+\verbatim
+ap1: STA 02:b5:64:63:30:63 IEEE 802.11: associated
+ap1: STA 02:b5:64:63:30:63 WPA: pairwise key handshake completed (WPA)

+ap1: STA 02:2a:c4:18:5b:f3 WPA: group key handshake completed (WPA)
+\endverbatim
+
+By default, driver_param is simulating a driver that uses the WPA/RSN
+IE generated by %wpa_supplicant. Driver-generated IE and AssocInfo
+events can be tested by adding \a use_associnfo=1 to the \a driver_param
+line in the configuration file. For example:
+
+\verbatim
+driver_param=test_socket=/tmp/Test/ap1 use_associnfo=1
+\endverbatim
+
+
+\section unit_tests Unit tests
+
+Number of the components (.c files) used in %wpa_supplicant define
+their own unit tests for automated validation of the basic
+functionality. Most of the tests for cryptographic algorithms are
+using standard test vectors to validate functionality. These tests can
+be useful especially when verifying port to a new CPU target.
+
+In most cases, these tests are implemented in the end of the same file
+with functions that are normally commented out, but ca be included by
+defining a pre-processor variable when building the file separately.
+The details of the needed build options are included in the Makefile
+(test-* targets). All automated unit tests can be run with
+
+\verbatim
+make tests
+\endverbatim
+
+This make target builds and runs each test and terminates with zero
+exit code if all tests were completed successfully.

+Automatic regression and interoperability testing of wpa_supplicant's
+IEEE 802.1X/EAPOL authentication
+
+Test program:
+- Linked some parts of IEEE 802.1X Authenticator implementation from
+  hostapd (RADIUS client and RADIUS processing, EAP<->RADIUS
+  encapsulation/decapsulation) into wpa_supplicant.
+- Replaced wpa_supplicant.c and wpa.c with test code that trigger
+  IEEE 802.1X authentication automatically without need for wireless
+  client card or AP.
+- For EAP methods that generate keying material, the key derived by the
+  Supplicant is verified to match with the one received by the (now
+  integrated) Authenticator.
+
+The full automated test suite can now be run in couple of seconds, but
+I'm more than willing to add new RADIUS authentication servers to make
+this take a bit more time.. ;-) As an extra bonus, this can also be
+seen as automatic regression/interoperability testing for the RADIUS
+server, too.
+
+In order for me to be able to use a new authentication server, the
+server need to be available from Internet (at least from one static IP
+address) and I will need to get suitable user name/password pairs,
+certificates, and private keys for testing use. Other alternative
+would be to get an evaluation version of the server so that I can
+install it on my own test setup. If you are interested in providing
+either server access or evaluation version, please contact me
+(j@w1.fi).

+1) PEAPv1 required new label, "client PEAP encryption" instead of "client EAP
+   encryption", during key derivation (requires phase1="peaplabel=1" in the
+   network configuration in wpa_supplicant.conf)
+2) used FreeRADIUS as inner auth server
+5) PEAPv1 required termination of negotiation on tunneled EAP-Success and new
+   label in key deriviation
+   (phase1="peap_outer_success=0 peaplabel=1") (in "IETF Draft 5" mode)
+6) Authenticator simulator required patching for handling Access-Accept within
+   negotiation (for the first EAP-Success of LEAP)
+7) tested only with an older (incompatible) draft of EAP-PSK; FreeRADIUS does
+   not support the current EAP-PSK (RFC) specification
+8) PEAPv1 used non-standard version negotiation (client had to force v1 even
+   though server reported v0 as the highest supported version)
+9) only EAP-TTLS/EAP-TNC tested, i.e., test did not include proper sequence of
+   client authentication followed by TNC inside the tunnel
+10) worked only with special compatibility code to match the IKEv2 server
+    implementation

+To do:
+- hostap: try other roaming modes
+  NOTE: current mode (manual roaming) does not really roam at all..
+  Firmware did not notice the current AP disappearing..
+- add support for WPA with ap_scan=0 (update selected cipher etc. based on
+  AssocInfo; make sure these match with configuration)
+- consider closing smart card / PCSC connection when EAP-SIM/EAP-AKA
+  authentication has been completed (cache scard data based on serial#(?)
+  and try to optimize next connection if the same card is present for next
+  auth)
+- on disconnect event, could try to associate with another AP if one is
+  present in scan results; would need to update scan results periodically..
+- if driver/hw is not WPA2 capable, must remove WPA_PROTO_RSN flag from
+  ssid->proto fields to avoid detecting downgrade attacks when the driver
+  is not reporting RSN IE, but msg 3/4 has one
+- Cisco AP and non-zero keyidx for unicast -> map to broadcast
+  (actually, this already works with driver_ndis; so maybe just change
+  driver_*.c to do the mapping for drivers that cannot handle non-zero keyidx
+  for unicast); worked also with Host AP driver and madwifi
+- IEEE 802.1X and key update with driver_ndis?? wpa_supplicant did not seem
+  to see unencrypted EAPOL-Key frames at all..
+- EAP-PAX with PAX_SEC
+- EAP (RFC 3748)
+  * OTP Extended Responses (Sect. 5.5)
+- test what happens if authenticator sends EAP-Success before real EAP
+  authentication ("canned" Success); this should be ignored based on
+  RFC 3748 Sect. 4.2
+- test compilation with gcc -W options (more warnings?)
+  (Done once; number of unused function arguments still present)
+- add proper support for using dot11RSNAConfigSATimeout
+- ctrl_iface: get/set/remove blob
+- use doc/docbook/*.sgml and docbook2{txt,html,pdf} to replace README and
+  web pages including the same information.. i.e., have this information only
+  in one page; how to build a PDF file with all the SGML included?
+- EAP-POTP/RSA SecurID profile (RFC 4793)
+- document wpa_gui build and consider adding it to 'make install'
+- test madwifi with pairwise=TKIP group=WEP104
+- possibility to link in WPA Authenticator state machine to wpa_supplicant
+  (new PeerKey handshake, WPA2/IEEE 802.11 (RSN) IBSS)
+- consider merging hostapd and wpa_supplicant PMKSA cache implementations
+- consider redesigning pending EAP requests (identity/password/otp from
+  ctrl_iface) by moving the retrying of the previous request into EAP
+  state machine so that EAPOL state machine is not needed for this
+- rfc4284.txt (network selection for eap)
+- www pages about configuring wpa_supplicant:
+  * global options (ap_scan, ctrl_interfaces) based on OS/driver
+  * network block
+  * key_mgmt selection
+  * WPA parameters
+  * EAP options (one page for each method)
+  * "configuration wizard" (step 1: select OS, step 2: select driver, ...) to
+    generate example configuration
+- error path in rsn_preauth_init: should probably deinit l2_packet handlers
+  if something fails; does something else need deinit?
+- consider moving SIM card functionality (IMSI fetching) away from eap.c;
+  this should likely happen before EAP is initialized for authentication;
+  now IMSI is read only after receiving EAP-Identity/Request, but since it is
+  really needed for all cases, reading IMSI and generating Identity string
+  could very well be done before EAP has been started
+- try to work around race in receiving association event and first EAPOL
+  message
+- add wpa_secure_memzero() macro and secure implementation (volatile u8*) to
+  clear memory; this would be used to clear temporary buffers containing
+  private data (e.g., keys); the macro can be defined to NOP in order to save
+  space (i.e., no code should depend on the macro doing something)
+- make sure that TLS session cache is not shared between EAP types or if it
+  is, that the cache entries are bound to only one EAP type; e.g., cache entry
+  created with EAP-TLS must not be allowed to do fast re-auth with EAP-TTLS
+- consider moving eap_tls_build_ack() call into eap_tls_process_helper()
+  (it seems to be called always if helper returns 1)
+  * could need to modify eap_{ttls,peap,fast}_decrypt to do same
+- add support for fetching full user cert chain from Windows certificate
+  stores even when there are intermediate CA certs that are not in the
+  configured ca_cert store (e.g., ROOT) (they could be, e.g., in CA store)
+
+
+0.6.x branch:
+- clean up common.[ch]
+- change TLS/crypto library interface to use a structure of function
+  pointers and helper inline functions (like driver_ops) instead of
+  requiring every TLS wrapper to implement all functions
+- add support for encrypted configuration fields (e.g., password, psk,
+  passphrase, pin)
+- wpa_gui: add support for setting and showing priority, auth_alg
+  (open/shared for static WEP)
+
+- cleanup TLS/PEAP/TTLS/FAST fragmentation: both the handshake and Appl. Data
+  phases should be able to use the same functions for this;
+  the last step in processing sent should be this code and rest of the code
+  should not need to care about fragmentation at all
+- test EAP-FAST peer with OpenSSL and verify that fallback to full handshake
+  (ServerHello followed by something else than ChangeCipherSpec)

+##### Example wpa_supplicant configuration file ###############################
+#
+# This file describes configuration file format and lists all available option.
+# Please also take a look at simpler configuration examples in 'examples'
+# subdirectory.
+#
+# Empty lines and lines starting with # are ignored
+
+# NOTE! This file may contain password information and should probably be made
+# readable only by root user on multiuser systems.
+
+# Note: All file paths in this configuration file should use full (absolute,
+# not relative to working directory) path in order to allow working directory
+# to be changed. This can happen if wpa_supplicant is run in the background.
+
+# Whether to allow wpa_supplicant to update (overwrite) configuration
+#
+# This option can be used to allow wpa_supplicant to overwrite configuration
+# file whenever configuration is changed (e.g., new network block is added with
+# wpa_cli or wpa_gui, or a password is changed). This is required for
+# wpa_cli/wpa_gui to be able to store the configuration changes permanently.
+# Please note that overwriting configuration file will remove the comments from
+# it.
+#update_config=1
+
+# global configuration (shared by all network blocks)
+#
+# Parameters for the control interface. If this is specified, wpa_supplicant
+# will open a control interface that is available for external programs to
+# manage wpa_supplicant. The meaning of this string depends on which control
+# interface mechanism is used. For all cases, the existance of this parameter
+# in configuration is used to determine whether the control interface is
+# enabled.
+#
+# For UNIX domain sockets (default on Linux and BSD): This is a directory that
+# will be created for UNIX domain sockets for listening to requests from
+# external programs (CLI/GUI, etc.) for status information and configuration.
+# The socket file will be named based on the interface name, so multiple
+# wpa_supplicant processes can be run at the same time if more than one
+# interface is used.
+# /var/run/wpa_supplicant is the recommended directory for sockets and by
+# default, wpa_cli will use it when trying to connect with wpa_supplicant.
+#
+# Access control for the control interface can be configured by setting the
+# directory to allow only members of a group to use sockets. This way, it is
+# possible to run wpa_supplicant as root (since it needs to change network
+# configuration and open raw sockets) and still allow GUI/CLI components to be
+# run as non-root users. However, since the control interface can be used to
+# change the network configuration, this access needs to be protected in many
+# cases. By default, wpa_supplicant is configured to use gid 0 (root). If you
+# want to allow non-root users to use the control interface, add a new group
+# and change this value to match with that group. Add users that should have
+# control interface access to this group. If this variable is commented out or
+# not included in the configuration file, group will not be changed from the
+# value it got by default when the directory or socket was created.
+#
+# When configuring both the directory and group, use following format:
+# DIR=/var/run/wpa_supplicant GROUP=wheel
+# DIR=/var/run/wpa_supplicant GROUP=0
+# (group can be either group name or gid)
+#
+# For UDP connections (default on Windows): The value will be ignored. This
+# variable is just used to select that the control interface is to be created.
+# The value can be set to, e.g., udp (ctrl_interface=udp)
+#
+# For Windows Named Pipe: This value can be used to set the security descriptor
+# for controlling access to the control interface. Security descriptor can be
+# set using Security Descriptor String Format (see http://msdn.microsoft.com/
+# library/default.asp?url=/library/en-us/secauthz/security/
+# security_descriptor_string_format.asp). The descriptor string needs to be
+# prefixed with SDDL=. For example, ctrl_interface=SDDL=D: would set an empty
+# DACL (which will reject all connections). See README-Windows.txt for more
+# information about SDDL string format.
+#
+ctrl_interface=/var/run/wpa_supplicant
+
+# IEEE 802.1X/EAPOL version
+# wpa_supplicant is implemented based on IEEE Std 802.1X-2004 which defines
+# EAPOL version 2. However, there are many APs that do not handle the new
+# version number correctly (they seem to drop the frames completely). In order
+# to make wpa_supplicant interoperate with these APs, the version number is set
+# to 1 by default. This configuration value can be used to set it to the new
+# version (2).
+eapol_version=1
+
+# AP scanning/selection
+# By default, wpa_supplicant requests driver to perform AP scanning and then
+# uses the scan results to select a suitable AP. Another alternative is to
+# allow the driver to take care of AP scanning and selection and use
+# wpa_supplicant just to process EAPOL frames based on IEEE 802.11 association
+# information from the driver.
+# 1: wpa_supplicant initiates scanning and AP selection
+# 0: driver takes care of scanning, AP selection, and IEEE 802.11 association
+#    parameters (e.g., WPA IE generation); this mode can also be used with
+#    non-WPA drivers when using IEEE 802.1X mode; do not try to associate with
+#    APs (i.e., external program needs to control association). This mode must
+#    also be used when using wired Ethernet drivers.
+# 2: like 0, but associate with APs using security policy and SSID (but not
+#    BSSID); this can be used, e.g., with ndiswrapper and NDIS drivers to
+#    enable operation with hidden SSIDs and optimized roaming; in this mode,
+#    the network blocks in the configuration file are tried one by one until
+#    the driver reports successful association; each network block should have
+#    explicit security policy (i.e., only one option in the lists) for
+#    key_mgmt, pairwise, group, proto variables
+ap_scan=1
+
+# EAP fast re-authentication
+# By default, fast re-authentication is enabled for all EAP methods that
+# support it. This variable can be used to disable fast re-authentication.
+# Normally, there is no need to disable this.
+fast_reauth=1
+
+# OpenSSL Engine support
+# These options can be used to load OpenSSL engines.
+# The two engines that are supported currently are shown below:
+# They are both from the opensc project (http://www.opensc.org/)
+# By default no engines are loaded.

+# configure the path to the pkcs11 module required by the pkcs11 engine
+#pkcs11_module_path=/usr/lib/pkcs11/opensc-pkcs11.so
+
+# Dynamic EAP methods
+# If EAP methods were built dynamically as shared object files, they need to be
+# loaded here before being used in the network blocks. By default, EAP methods
+# are included statically in the build, so these lines are not needed

+#
+# ssid: SSID (mandatory); either as an ASCII string with double quotation or

+#
+# scan_ssid:
+#	0 = do not scan this SSID with specific Probe Request frames (default)
+#	1 = scan with SSID-specific Probe Request frames (this can be used to

+#
+# bssid: BSSID (optional); if set, this network block is used only when

+#
+# priority: priority group (integer)
+# By default, all networks will get same priority group (0). If some of the

+# priority groups will be iterated in decreasing priority (i.e., the larger the
+# priority value, the sooner the network is matched against the scan results).
+# Within each priority group, networks will be selected based on security
+# policy, signal strength, etc.
+# Please note that AP scanning with scan_ssid=1 and ap_scan=2 mode are not
+# using this priority to select the order for scanning. Instead, they try the
+# networks in the order that used in the configuration file.
+#
+# mode: IEEE 802.11 operation mode
+# 0 = infrastructure (Managed) mode, i.e., associate with an AP (default)
+# 1 = IBSS (ad-hoc, peer-to-peer)
+# Note: IBSS can only be used with key_mgmt NONE (plaintext and static WEP)
+# and key_mgmt=WPA-NONE (fixed group key TKIP/CCMP). In addition, ap_scan has
+# to be set to 2 for IBSS. WPA-None requires following network block options:
+# proto=WPA, key_mgmt=WPA-NONE, pairwise=NONE, group=TKIP (or CCMP, but not
+# both), and psk must also be set.
+#
+# frequency: Channel frequency in megahertz (MHz) for IBSS, e.g.,
+# 2412 = IEEE 802.11b/g channel 1. This value is used to configure the initial
+# channel for IBSS (adhoc) networks. It is ignored in the infrastructure mode.
+# In addition, this value is only used by the station that creates the IBSS. If
+# an IBSS network with the configured SSID is already present, the frequency of
+# the network will be used instead of this configured value.
+#
+# proto: list of accepted protocols
+# WPA = WPA/IEEE 802.11i/D3.0
+# RSN = WPA2/IEEE 802.11i (also WPA2 can be used as an alias for RSN)
+# If not set, this defaults to: WPA RSN
+#
+# key_mgmt: list of accepted authenticated key management protocols
+# WPA-PSK = WPA pre-shared key (this requires 'psk' field)
+# WPA-EAP = WPA using EAP authentication

+# The key used in WPA-PSK mode can be entered either as 64 hex-digits, i.e.,
+# 32 bytes or as an ASCII passphrase (in which case, the real PSK will be
+# generated using the passphrase and SSID). ASCII passphrase must be between
+# 8 and 63 characters (inclusive).
+# This field is not needed, if WPA-EAP is used.
+# Note: Separate tool, wpa_passphrase, can be used to generate 256-bit keys
+# from ASCII passphrase. This process uses lot of CPU and wpa_supplicant

+# Following fields are only used with internal EAP implementation.
+# eap: space-separated list of accepted EAP methods
+#	MD5 = EAP-MD5 (unsecure and does not generate keying material ->
+#			cannot be used with WPA; to be used as a Phase 2 method
+#			with EAP-PEAP or EAP-TTLS)
+#       MSCHAPV2 = EAP-MSCHAPv2 (cannot be used separately with WPA; to be used
+#		as a Phase 2 method with EAP-PEAP or EAP-TTLS)
+#       OTP = EAP-OTP (cannot be used separately with WPA; to be used
+#		as a Phase 2 method with EAP-PEAP or EAP-TTLS)
+#       GTC = EAP-GTC (cannot be used separately with WPA; to be used
+#		as a Phase 2 method with EAP-PEAP or EAP-TTLS)
+#	TLS = EAP-TLS (client and server certificate)
+#	PEAP = EAP-PEAP (with tunnelled EAP authentication)
+#	TTLS = EAP-TTLS (with tunnelled EAP or PAP/CHAP/MSCHAP/MSCHAPV2
+#			 authentication)
+#	If not set, all compiled in methods are allowed.
+#
+# identity: Identity string for EAP
+#	This field is also used to configure user NAI for
+#	EAP-PSK/PAX/SAKE/GPSK.
+# anonymous_identity: Anonymous identity string for EAP (to be used as the
+#	unencrypted identity with EAP types that support different tunnelled
+#	identity, e.g., EAP-TTLS)
+# password: Password string for EAP. This field can include either the
+#	plaintext password (using ASCII or hex string) or a NtPasswordHash
+#	(16-byte MD4 hash of password) in hash:<32 hex digits> format.
+#	NtPasswordHash can only be used when the password is for MSCHAPv2 or
+#	MSCHAP (EAP-MSCHAPv2, EAP-TTLS/MSCHAPv2, EAP-TTLS/MSCHAP, LEAP).
+#	EAP-PSK (128-bit PSK), EAP-PAX (128-bit PSK), and EAP-SAKE (256-bit
+#	PSK) is also configured using this field. For EAP-GPSK, this is a
+#	variable length PSK.
+# ca_cert: File path to CA certificate file (PEM/DER). This file can have one
+#	or more trusted CA certificates. If ca_cert and ca_path are not
+#	included, server certificate will not be verified. This is insecure and
+#	a trusted CA certificate should always be configured when using
+#	EAP-TLS/TTLS/PEAP. Full path should be used since working directory may
+#	change when wpa_supplicant is run in the background.
+#	On Windows, trusted CA certificates can be loaded from the system
+#	certificate store by setting this to cert_store://<name>, e.g.,
+#	ca_cert="cert_store://CA" or ca_cert="cert_store://ROOT".
+#	Note that when running wpa_supplicant as an application, the user
+#	certificate store (My user account) is used, whereas computer store
+#	(Computer account) is used when running wpasvc as a service.
+# ca_path: Directory path for CA certificate files (PEM). This path may
+#	contain multiple CA certificates in OpenSSL format. Common use for this
+#	is to point to system trusted CA list which is often installed into
+#	directory like /etc/ssl/certs. If configured, these certificates are
+#	added to the list of trusted CAs. ca_cert may also be included in that
+#	case, but it is not required.
+# client_cert: File path to client certificate file (PEM/DER)
+#	Full path should be used since working directory may change when
+#	wpa_supplicant is run in the background.
+#	Alternatively, a named configuration blob can be used by setting this
+#	to blob://<blob name>.
+# private_key: File path to client private key file (PEM/DER/PFX)
+#	When PKCS#12/PFX file (.p12/.pfx) is used, client_cert should be
+#	commented out. Both the private key and certificate will be read from
+#	the PKCS#12 file in this case. Full path should be used since working
+#	directory may change when wpa_supplicant is run in the background.
+#	Windows certificate store can be used by leaving client_cert out and
+#	configuring private_key in one of the following formats:
+#	cert://substring_to_match
+#	hash://certificate_thumbprint_in_hex
+#	for example: private_key="hash://63093aa9c47f56ae88334c7b65a4"
+#	Note that when running wpa_supplicant as an application, the user
+#	certificate store (My user account) is used, whereas computer store
+#	(Computer account) is used when running wpasvc as a service.
+#	Alternatively, a named configuration blob can be used by setting this
+#	to blob://<blob name>.
+# private_key_passwd: Password for private key file (if left out, this will be
+#	asked through control interface)
+# dh_file: File path to DH/DSA parameters file (in PEM format)
+#	This is an optional configuration file for setting parameters for an
+#	ephemeral DH key exchange. In most cases, the default RSA
+#	authentication does not use this configuration. However, it is possible
+#	setup RSA to use ephemeral DH key exchange. In addition, ciphers with
+#	DSA keys always use ephemeral DH keys. This can be used to achieve
+#	forward secrecy. If the file is in DSA parameters format, it will be
+#	automatically converted into DH params.
+# subject_match: Substring to be matched against the subject of the
+#	authentication server certificate. If this string is set, the server
+#	sertificate is only accepted if it contains this string in the subject.
+#	The subject string is in following format:
+#	/C=US/ST=CA/L=San Francisco/CN=Test AS/emailAddress=as@example.com
+# altsubject_match: Semicolon separated string of entries to be matched against
+#	the alternative subject name of the authentication server certificate.
+#	If this string is set, the server sertificate is only accepted if it
+#	contains one of the entries in an alternative subject name extension.
+#	altSubjectName string is in following format: TYPE:VALUE
+#	Example: EMAIL:server@example.com
+#	Example: DNS:server.example.com;DNS:server2.example.com
+#	Following types are supported: EMAIL, DNS, URI
+# phase1: Phase1 (outer authentication, i.e., TLS tunnel) parameters
+#	(string with field-value pairs, e.g., "peapver=0" or
+#	"peapver=1 peaplabel=1")
+#	'peapver' can be used to force which PEAP version (0 or 1) is used.
+#	'peaplabel=1' can be used to force new label, "client PEAP encryption",
+#	to be used during key derivation when PEAPv1 or newer. Most existing
+#	PEAPv1 implementation seem to be using the old label, "client EAP
+#	encryption", and wpa_supplicant is now using that as the default value.
+#	Some servers, e.g., Radiator, may require peaplabel=1 configuration to
+#	interoperate with PEAPv1; see eap_testing.txt for more details.
+#	'peap_outer_success=0' can be used to terminate PEAP authentication on
+#	tunneled EAP-Success. This is required with some RADIUS servers that
+#	implement draft-josefsson-pppext-eap-tls-eap-05.txt (e.g.,
+#	Lucent NavisRadius v4.4.0 with PEAP in "IETF Draft 5" mode)
+#	include_tls_length=1 can be used to force wpa_supplicant to include
+#	TLS Message Length field in all TLS messages even if they are not
+#	fragmented.
+#	sim_min_num_chal=3 can be used to configure EAP-SIM to require three
+#	challenges (by default, it accepts 2 or 3)
+#	result_ind=1 can be used to enable EAP-SIM and EAP-AKA to use
+#	protected result indication.
+#	'crypto_binding' option can be used to control PEAPv0 cryptobinding
+#	behavior:
+#	 * 0 = do not use cryptobinding (default)
+#	 * 1 = use cryptobinding if server supports it
+#	 * 2 = require cryptobinding
+#	EAP-WSC (WPS) uses following options: pin=<Device Password> or
+#	pbc=1.
+# phase2: Phase2 (inner authentication with TLS tunnel) parameters
+#	(string with field-value pairs, e.g., "auth=MSCHAPV2" for EAP-PEAP or
+#	"autheap=MSCHAPV2 autheap=MD5" for EAP-TTLS)
+# Following certificate/private key fields are used in inner Phase2
+# authentication when using EAP-TTLS or EAP-PEAP.
+# ca_cert2: File path to CA certificate file. This file can have one or more
+#	trusted CA certificates. If ca_cert2 and ca_path2 are not included,
+#	server certificate will not be verified. This is insecure and a trusted

+# dh_file2: File path to DH/DSA parameters file (in PEM format)
+# subject_match2: Substring to be matched against the subject of the

+# altsubject_match2: Substring to be matched against the alternative subject
+#	name of the authentication server certificate.
+#
+# fragment_size: Maximum EAP fragment size in bytes (default 1398).
+#	This value limits the fragment size for EAP methods that support
+#	fragmentation (e.g., EAP-TLS and EAP-PEAP). This value should be set
+#	small enough to make the EAP messages fit in MTU of the network
+#	interface used for EAPOL. The default value is suitable for most
+#	cases.
+#
+# EAP-FAST variables:
+# pac_file: File path for the PAC entries. wpa_supplicant will need to be able
+#	to create this file and write updates to it when PAC is being
+#	provisioned or refreshed. Full path to the file should be used since
+#	working directory may change when wpa_supplicant is run in the
+#	background. Alternatively, a named configuration blob can be used by
+#	setting this to blob://<blob name>
+# phase1: fast_provisioning option can be used to enable in-line provisioning
+#         of EAP-FAST credentials (PAC):
+#         0 = disabled,
+#         1 = allow unauthenticated provisioning,
+#         2 = allow authenticated provisioning,
+#         3 = allow both unauthenticated and authenticated provisioning
+#	fast_max_pac_list_len=<num> option can be used to set the maximum
+#		number of PAC entries to store in a PAC list (default: 10)
+#	fast_pac_format=binary option can be used to select binary format for
+#		storing PAC entries in order to save some space (the default
+#		text format uses about 2.5 times the size of minimal binary
+#		format)
+#
+# wpa_supplicant supports number of "EAP workarounds" to work around
+# interoperability issues with incorrectly behaving authentication servers.
+# These are enabled by default because some of the issues are present in large
+# number of authentication servers. Strict EAP conformance mode can be
+# configured by disabling workarounds with eap_workaround=0.
