ChangeLog for hostapd
2005-06-10 - v0.3.9
* 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
* fixed WPA2 to add PMKSA cache entry when using integrated EAP
authenticator
* driver_madwifi: fixed pairwise key removal to allow WPA reauth
without disassociation
* fixed RADIUS attribute Class processing to only use Access-Accept
packets to update Class; previously, other RADIUS authentication
packets could have cleared Class attribute
* fixed PMKSA caching (EAP authentication was not skipped correctly
with the new state machine changes from IEEE 802.1X draft)
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.
