-		    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.

-	  (retransmissions from RADIUS client) by replying with the previous
-	  reply
-
-2006-12-31 - v0.5.7
-	* 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

-	  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

-	  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
-

-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.
-
-	madwifi driver for cards based on Atheros chip set (ar521x)
-	(http://sourceforge.net/projects/madwifi/)
-	Please note that you will need to add the correct path for
-	madwifi driver root directory in .config (see defconfig file for
-	an example: CFLAGS += -I<path>)
-
-	Prism54 driver for Intersil/Conexant Prism GT/Duette/Indigo
-	(http://www.prism54.org/)
-
-	Any wired Ethernet driver for wired IEEE 802.1X authentication
-	(experimental code)
-
-	FreeBSD -current (with some kernel mods that have not yet been
-	committed when hostapd v0.3.0 was released)
-	BSD net80211 layer (e.g., Atheros driver)
-
-
-Build configuration
--------------------
-
-In order to be able to build hostapd, you will need to create a build
-time configuration file, .config that selects which optional
-components are included. See defconfig file for example configuration
-and list of available options.
-
-
-
-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 configuration for WPA/WPA2

-
-# Enable WPA. Setting this variable configures the AP to require WPA (either

-# For WPA-RADIUS/EAP, ieee8021x must be set (but without dynamic WEP keys),
-# RADIUS authentication server must be configured, and WPA-EAP must be included

-# TKIP = Temporal Key Integrity Protocol [IEEE 802.11i]
-# Group cipher suite (encryption algorithm for broadcast and multicast frames)
-# is automatically selected based on this configuration. If only CCMP is

- * required. When TLS is enabled (e.g., by enabling EAP-TLS or EAP-PEAP), the
- * crypto library used by the TLS implementation is expected to be used for
- * non-TLS needs, too, in order to save space by not implementing these
- * functions twice.
- *
- * Wrapper code for using each crypto library is in its own file (crypto*.c)
- * and one of these files is build and linked in to provide the functions

-/**
-\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.

-# This script reads a C source file from stdin, and writes

-#
-# $ mv file.c file.c.gtkdoc
-# $ kerneldoc2doxygen.pl <file.c.gtkdoc >file.c
-#
-# Or to do the same thing with multiple files:
-# $ perl -i.gtkdoc kerneldoc2doxygen.pl *.c *.h
-#
-# This script may also be suitable for use as a Doxygen input filter,
-# but that has not been tested.

-# Back up your source files before using this script!!

-\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++.

- *
- * 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.

-.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 .

-# Listen N usecs on each channel when doing passive scanning.
-# This value plus the time needed for changing channels should be less than
-# 32 milliseconds (i.e. 32000 usec) to avoid interruptions to normal
-# operations. Time needed for channel changing varies based on the used wlan
-# hardware.
-# default: disabled (0)
-#passive_scan_listen=10000
-
-# Passive scanning mode:
-# 0 = scan all supported modes (802.11a/b/g/Turbo) (default)
-# 1 = scan only the mode that is currently used for normal operations
-#passive_scan_mode=1
-
-# Maximum number of entries kept in AP table (either for passive scanning or
-# for detecting Overlapping Legacy BSS Condition). The oldest entry will be
-# removed when adding a new entry that would make the list grow over this
-# limit. Note! Wi-Fi certification for IEEE 802.11g requires that OLBC is
-# enabled, so this field should not be set to 0 when using IEEE 802.11g.
-# default: 255
-#ap_table_max_size=255
-
-# Number of seconds of no frames received after which entries may be deleted
-# from the AP table. Since passive scanning is not usually performed frequently
-# this should not be set to very small value. In addition, there is no
-# guarantee that every scan cycle will receive beacon frames from the
-# neighboring APs.
-# default: 60
-#ap_table_expiration_time=3600
-
-# Multiple BSSID support
-#
-# Above configuration is using the default interface (wlan#, or multi-SSID VLAN
-# interfaces). Other BSSIDs can be added by using separator 'bss' with
-# default interface name to be allocated for the data packets of the new BSS.
-#
-# hostapd will generate BSSID mask based on the BSSIDs that are
-# configured. hostapd will verify that dev_addr & MASK == dev_addr. If this is
-# not the case, the MAC address of the radio must be changed before starting
-# hostapd (ifconfig wlan0 hw ether <MAC addr>).
-#
-# BSSIDs are assigned in order to each BSS, unless an explicit BSSID is
-# specified using the 'bssid' parameter.
-# If an explicit BSSID is specified, it must be chosen such that it:
-# - 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
-#
-# Please note that hostapd uses some of the values configured for the first BSS
-# as the defaults for the following BSSes. However, it is recommended that all
-# BSSes include explicit configuration of all relevant configuration items.
-#

-# 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-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 and EAP-TTLS 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

-SHA-1 in C

-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'
