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 ') * 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.
