571	* Add channel selection support in hostapd. See hostapd.conf.
572	* Add support for IEEE 802.11v Time Advertisement mechanism with UTC
573	  TSF offset. See hostapd.conf for config info.
574	* Delay STA entry removal until Deauth/Disassoc TX status in AP mode.
575	  This allows the driver to use PS buffering of Deauthentication and
576	  Disassociation frames when the STA is in power save sleep. Only
577	  available with drivers that provide TX status events for Deauth/
578	  Disassoc frames (nl80211).

582	* bsd: Add support for setting HT values in IFM_MMASK.
583	* Allow client isolation to be configured with ap_isolate. Client
584	  isolation can be used to prevent low-level bridging of frames
585	  between associated stations in the BSS. By default, this bridging
586	  is allowed.
587	* Allow coexistance of HT BSSes with WEP/TKIP BSSes.

591	* Add support for writing debug log to a file using "-f" option. Also
592	  add relog CLI command to re-open the log file.
593	* Add bridge handling for WDS STA interfaces. By default they are
594	  added to the configured bridge of the AP interface (if present),
595	  but the user can also specify a separate bridge using cli command
596	  wds_bridge.
597	* hostapd_cli:

599	    interfaces.
600	  - Add relog command for reopening log file.
601	  - Send AP-STA-DISCONNECTED event when an AP disconnects a station
602	    due to inactivity.
603	  - Add wps_config ctrl_interface command for configuring AP. This
604	    command can be used to configure the AP using the internal WPS
605	    registrar. It works in the same way as new AP settings received
606	    from an ER.
607	  - Many WPS/WPS ER commands - see WPS/WPS ER sections for details.
608	  - Add command get version, that returns hostapd version string.
609	* WNM: Add BSS Transition Management Request for ESS Disassoc Imminent.
610	  Use hostapd_cli ess_disassoc (STA addr) (URL) to send the
611	  notification to the STA.
612	* Allow AP mode to disconnect STAs based on low ACK condition (when
613	  the data connection is not working properly, e.g., due to the STA
614	  going outside the range of the AP). Disabled by default, enable by
615	  config option disassoc_low_ack.
616	* Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad
617	  config file.
618	* WPS:
619	  - Send AP Settings as a wrapped Credential attribute to ctrl_iface
620	    in WPS-NEW-AP-SETTINGS.
621	  - Dispatch more WPS events through hostapd ctrl_iface.
622	  - Add mechanism for indicating non-standard WPS errors.
623	  - Change concurrent radio AP to use only one WPS UPnP instance.
624	  - Add wps_check_pin command for processing PIN from user input.
625	    UIs can use this command to process a PIN entered by a user and to
626	    validate the checksum digit (if present).
627	  - Add hostap_cli get_config command to display current AP config.
628	  - Add new hostapd_cli command, wps_ap_pin, to manage AP PIN at
629	    runtime and support dynamic AP PIN management.
630	  - Disable AP PIN after 10 consecutive failures. Slow down attacks
631	    on failures up to 10.
632	  - Allow AP to start in Enrollee mode without AP PIN for probing,
633	    to be compatible with Windows 7.
634	  - Add Config Error into WPS-FAIL events to provide more info
635	    to the user on how to resolve the issue.
636	  - When controlling multiple interfaces:
637	     - apply WPS commands to all interfaces configured to use WPS
638	     - apply WPS config changes to all interfaces that use WPS
639	     - when an attack is detected on any interface, disable AP PIN on
640	       all interfaces
641	* WPS ER:
642	  - Show SetSelectedRegistrar events as ctrl_iface events.
643	  - Add special AP Setup Locked mode to allow read only ER.
644	    ap_setup_locked=2 can now be used to enable a special mode where
645	    WPS ER can learn the current AP settings, but cannot change them.
646	* WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2)
647	  - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool
648	    for testing protocol extensibility.
649	  - Add build option CONFIG_WPS_STRICT to allow disabling of WPS
650	    workarounds.
651	  - Add support for AuthorizedMACs attribute.
652	* TDLS:
653	  - Allow TDLS use or TDLS channel switching in the BSS to be
654	    prohibited in the BSS, using config params tdls_prohibit and
655	    tdls_prohibit_chan_switch.
656	* EAP server: Add support for configuring fragment size (see
657	  fragment_size in hostapd.conf).
658	* wlantest: Add a tool wlantest for IEEE802.11 protocol testing.
659	  wlantest can be used to capture frames from a monitor interface
660	  for realtime capturing or from pcap files for offline analysis.
661	* Interworking: Support added for 802.11u. Enable in .config with
662	  CONFIG_INTERWORKING. See hostapd.conf for config parameters for
663	  interworking.
664	* Android: Add build and runtime support for Android hostapd.
665	* Add a new debug message level for excessive information. Use
666	  -ddd to enable.
667	* TLS: Add support for tls_disable_time_checks=1 in client mode.
668	* Internal TLS:
669	  - Add support for TLS v1.1 (RFC 4346). Enable with build parameter
670	    CONFIG_TLSV11.
671	  - Add domainComponent parser for X.509 names
672	* Reorder some IEs to get closer to IEEE 802.11 standard. Move
673	  WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames.
674	  Move HT IEs to be later in (Re)Assoc Resp.
675	* Many bugfixes.

681	  configuration options
682	* TNC: fixed issues with fragmentation
683	* EAP-TNC: add Flags field into fragment acknowledgement (needed to

693	* hostapd_notif_Assoc() can now be called with all IEs to simplify
694	  driver wrappers
695	* work around interoperability issue with some WPS External Registrar
696	  implementations
697	* nl80211: fix WPS IE update
698	* hostapd_cli: add support for action script operations (run a script
699	  on hostapd events)
700	* fix DH padding with internal crypto code (mainly, for WPS)
701	* fix WPS association with both WPS IE and WPA/RSN IE present with
702	  driver wrappers that use hostapd MLME (e.g., nl80211)
703
7042010-01-16 - v0.7.1
705	* cleaned up driver wrapper API (struct wpa_driver_ops); the new API
706	  is not fully backwards compatible, so out-of-tree driver wrappers
707	  will need modifications
708	* cleaned up various module interfaces
709	* merge hostapd and wpa_supplicant developers' documentation into a
710	  single document

722	  driver=nl80211 for now)
723	* fixed WPS Probe Request processing to handle missing required
724	  attribute
725	* fixed PKCS#12 use with OpenSSL 1.0.0
726	* detect bridge interface automatically so that bridge parameter in
727	  hostapd.conf becomes optional (though, it may now be used to
728	  automatically add then WLAN interface into a bridge with
729	  driver=nl80211)
730
7312009-11-21 - v0.7.0
732	* increased hostapd_cli ping interval to 5 seconds and made this
733	  configurable with a new command line options (-G<seconds>)
734	* driver_nl80211: use Linux socket filter to improve performance
735	* added support for external Registrars with WPS (UPnP transport)
736	* 802.11n: scan for overlapping BSSes before starting 20/40 MHz channel

740	  Drives (UFD) (CONFIG_WPS_UFD=y)
741	* fixed EAPOL/EAP reauthentication when using an external RADIUS
742	  authentication server
743	* fixed TNC with EAP-TTLS

746	* fixed SHA-256 based key derivation function to match with the
747	  standard when using CCMP (for IEEE 802.11r and IEEE 802.11w)
748	  (note: this breaks interoperability with previous version) [Bug 307]
749	* added number of code size optimizations to remove unnecessary
750	  functionality from the program binary based on build configuration
751	  (part of this automatic; part configurable with CONFIG_NO_* build
752	  options)
753	* use shared driver wrapper files with wpa_supplicant
754	* driver_nl80211: multiple updates to provide support for new Linux
755	  nl80211/mac80211 functionality

761	  networks
762	* added support for NFC out-of-band mechanism with WPS
763	* added preliminary support for IEEE 802.11r RIC processing
764
7652009-01-06 - v0.6.7
766	* added support for Wi-Fi Protected Setup (WPS)
767	  (hostapd can now be configured to act as an integrated WPS Registrar
768	  and provision credentials for WPS Enrollees using PIN and PBC
769	  methods; external wireless Registrar can configure the AP, but
770	  external WLAN Manager Registrars are not supported); WPS support can
771	  be enabled by adding CONFIG_WPS=y into .config and setting the
772	  runtime configuration variables in hostapd.conf (see WPS section in
773	  the example configuration file); new hostapd_cli commands wps_pin and
774	  wps_pbc are used to configure WPS negotiation; see README-WPS for
775	  more details
776	* added IEEE 802.11n HT capability configuration (ht_capab)
777	* added support for generating Country IE based on nl80211 regulatory

786
7872008-11-23 - v0.6.6
788	* added a new configuration option, wpa_ptk_rekey, that can be used to
789	  enforce frequent PTK rekeying, e.g., to mitigate some attacks against
790	  TKIP deficiencies
791	* updated OpenSSL code for EAP-FAST to use an updated version of the
792	  session ticket overriding API that was included into the upstream
793	  OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
794	  needed with that version anymore)
795	* changed channel flags configuration to read the information from
796	  the driver (e.g., via driver_nl80211 when using mac80211) instead of
797	  using hostapd as the source of the regulatory information (i.e.,
798	  information from CRDA is now used with mac80211); this allows 5 GHz
799	  channels to be used with hostapd (if allowed in the current
800	  regulatory domain)
801	* fixed EAP-TLS message processing for the last TLS message if it is
802	  large enough to require fragmentation (e.g., if a large Session
803	  Ticket data is included)
804	* fixed listen interval configuration for nl80211 drivers
805
8062008-11-01 - v0.6.5
807	* added support for SHA-256 as X.509 certificate digest when using the
808	  internal X.509/TLSv1 implementation
809	* fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer
810	  identity lengths)
811	* fixed internal TLSv1 implementation for abbreviated handshake (used
812	  by EAP-FAST server)
813	* added support for setting VLAN ID for STAs based on local MAC ACL
814	  (accept_mac_file) as an alternative for RADIUS server-based
815	  configuration
816	* updated management frame protection to use IEEE 802.11w/D6.0
817	  (adds a new association ping to protect against unauthenticated
818	  authenticate or (re)associate request frames dropping association)
819	* added support for using SHA256-based stronger key derivation for WPA2
820	  (IEEE 802.11w)
821	* added new "driver wrapper" for RADIUS-only configuration
822	  (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config)
823	* fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2)
824	  is enabled in configuration
825	* changed EAP-FAST configuration to use separate fields for A-ID and
826	  A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed
827	  16-octet len binary value for better interoperability with some peer
828	  implementations; eap_fast_a_id is now configured as a hex string
829	* driver_nl80211: Updated to match the current Linux mac80211 AP mode
830	  configuration (wireless-testing.git and Linux kernel releases
831	  starting from 2.6.29)
832
8332008-08-10 - v0.6.4
834	* added peer identity into EAP-FAST PAC-Opaque and skip Phase 2
835	  Identity Request if identity is already known
836	* added support for EAP Sequences in EAP-FAST Phase 2
837	* added support for EAP-TNC (Trusted Network Connect)
838	  (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST
839	  changes needed to run two methods in sequence (IF-T) and the IF-IMV
840	  and IF-TNCCS interfaces from TNCS)
841	* added support for optional cryptobinding with PEAPv0
842	* added fragmentation support for EAP-TNC
843	* added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled)
844	  data
845	* added support for opportunistic key caching (OKC)
846
8472008-02-22 - v0.6.3
848	* fixed Reassociation Response callback processing when using internal
849	  MLME (driver_{hostap,nl80211,test}.c)
850	* updated FT support to use the latest draft, IEEE 802.11r/D9.0
851	* copy optional Proxy-State attributes into RADIUS response when acting
852	  as a RADIUS authentication server
853	* fixed EAPOL state machine to handle a case in which no response is
854	  received from the RADIUS authentication server; previous version
855	  could have triggered a crash in some cases after a timeout
856	* fixed EAP-SIM/AKA realm processing to allow decorated usernames to
857	  be used
858	* added a workaround for EAP-SIM/AKA peers that include incorrect null
859	  termination in the username
860	* fixed EAP-SIM/AKA protected result indication to include AT_COUNTER
861	  attribute in notification messages only when using fast
862	  reauthentication
863	* fixed EAP-SIM Start response processing for fast reauthentication
864	  case
865	* added support for pending EAP processing in EAP-{PEAP,TTLS,FAST}
866	  phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method
867
8682008-01-01 - v0.6.2
869	* fixed EAP-SIM and EAP-AKA message parser to validate attribute
870	  lengths properly to avoid potential crash caused by invalid messages
871	* added data structure for storing allocated buffers (struct wpabuf);
872	  this does not affect hostapd usage, but many of the APIs changed
873	  and various interfaces (e.g., EAP) is not compatible with old
874	  versions
875	* added support for protecting EAP-AKA/Identity messages with
876	  AT_CHECKCODE (optional feature in RFC 4187)
877	* added support for protected result indication with AT_RESULT_IND for
878	  EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1)
879	* added support for configuring EAP-TTLS phase 2 non-EAP methods in
880	  EAP server configuration; previously all four were enabled for every
881	  phase 2 user, now all four are disabled by default and need to be
882	  enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP,
883	  TTLS-MSCHAPV2
884	* removed old debug printing mechanism and the related 'debug'
885	  parameter in the configuration file; debug verbosity is now set with
886	  -d (or -dd) command line arguments
887	* added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
888	  only shared key/password authentication is supported in this version
889
8902007-11-24 - v0.6.1
891	* added experimental, integrated TLSv1 server implementation with the
892	  needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
893	  setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
894	  .config); this can be useful, e.g., if the target system does not
895	  have a suitable TLS library and a minimal code size is required
896	* added support for EAP-FAST server method to the integrated EAP
897	  server
898	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
899	  draft (draft-ietf-emu-eap-gpsk-07.txt)
900	* added a new configuration parameter, rsn_pairwise, to allow different
901	  pairwise cipher suites to be enabled for WPA and RSN/WPA2
902	  (note: if wpa_pairwise differs from rsn_pairwise, the driver will
903	  either need to support this or will have to use the WPA/RSN IEs from
904	  hostapd; currently, the included madwifi and bsd driver interfaces do
905	  not have support for this)
906	* updated FT support to use the latest draft, IEEE 802.11r/D8.0
907
9082007-05-28 - v0.6.0
909	* added experimental IEEE 802.11r/D6.0 support
910	* updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
911	* updated EAP-PSK to use the IANA-allocated EAP type 47
912	* fixed EAP-PSK bit ordering of the Flags field
913	* fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
914	  by reading wpa_psk_file [Bug 181]
915	* fixed EAP-TTLS AVP parser processing for too short AVP lengths
916	* fixed IPv6 connection to RADIUS accounting server
917	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
918	  draft (draft-ietf-emu-eap-gpsk-04.txt)
919	* hlr_auc_gw: read GSM triplet file into memory and rotate through the
920	  entries instead of only using the same three triplets every time
921	  (this does not work properly with tests using multiple clients, but
922	  provides bit better triplet data for testing a single client; anyway,
923	  if a better quality triplets are needed, GSM-Milenage should be used
924	  instead of hardcoded triplet file)
925	* fixed EAP-MSCHAPv2 server to use a space between S and M parameters
926	  in Success Request [Bug 203]
927	* added support for sending EAP-AKA Notifications in error cases
928	* updated to use IEEE 802.11w/D2.0 for management frame protection
929	  (still experimental)
930	* RADIUS server: added support for processing duplicate messages
931	  (retransmissions from RADIUS client) by replying with the previous
932	  reply
933
9342006-11-24 - v0.5.6
935	* added support for configuring and controlling multiple BSSes per
936	  radio interface (bss=<ifname> in hostapd.conf); this is only
937	  available with Devicescape and test driver interfaces
938	* fixed PMKSA cache update in the end of successful RSN
939	  pre-authentication
940	* added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
941	  for each STA based on RADIUS Access-Accept attributes); this requires
942	  VLAN support from the kernel driver/802.11 stack and this is
943	  currently only available with Devicescape and test driver interfaces
944	* driver_madwifi: fixed configuration of unencrypted modes (plaintext
945	  and IEEE 802.1X without WEP)
946	* removed STAKey handshake since PeerKey handshake has replaced it in
947	  IEEE 802.11ma and there are no known deployments of STAKey
948	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
949	  draft (draft-ietf-emu-eap-gpsk-01.txt)
950	* added preliminary implementation of IEEE 802.11w/D1.0 (management
951	  frame protection)
952	  (Note: this requires driver support to work properly.)
953	  (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
954	* hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
955	* hlr_auc_gw: added support for reading per-IMSI Milenage keys and
956	  parameters from a text file to make it possible to implement proper
957	  GSM/UMTS authentication server for multiple SIM/USIM cards using
958	  EAP-SIM/EAP-AKA
959	* fixed session timeout processing with drivers that do not use
960	  ieee802_11.c (e.g., madwifi)
961
9622006-08-27 - v0.5.5
963	* added 'hostapd_cli new_sta <addr>' command for adding a new STA into
964	  hostapd (e.g., to initialize wired network authentication based on an
965	  external signal)
966	* fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
967	  using WPA2 even if PMKSA caching is not used
968	* added -P<pid file> argument for hostapd to write the current process
969	  id into a file
970	* added support for RADIUS Authentication Server MIB (RFC 2619)
971
9722006-06-20 - v0.5.4
973	* fixed nt_password_hash build [Bug 144]
974	* added PeerKey handshake implementation for IEEE 802.11e
975	  direct link setup (DLS) to replace STAKey handshake
976	* added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
977	  draft-clancy-emu-eap-shared-secret-00.txt)
978	* fixed a segmentation fault when RSN pre-authentication was completed
979	  successfully [Bug 152]
980
9812006-04-27 - v0.5.3
982	* do not build nt_password_hash and hlr_auc_gw by default to avoid
983	  requiring a TLS library for a successful build; these programs can be
984	  build with 'make nt_password_hash' and 'make hlr_auc_gw'
985	* added a new configuration option, eapol_version, that can be used to
986	  set EAPOL version to 1 (default is 2) to work around broken client
987	  implementations that drop EAPOL frames which use version number 2
988	  [Bug 89]
989	* added support for EAP-SAKE (no EAP method number allocated yet, so
990	  this is using the same experimental type 255 as EAP-PSK)
991	* fixed EAP-MSCHAPv2 message length validation
992
9932006-03-19 - v0.5.2
994	* fixed stdarg use in hostapd_logger(): if both stdout and syslog
995	  logging was enabled, hostapd could trigger a segmentation fault in
996	  vsyslog on some CPU -- C library combinations
997	* moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
998	  program to make it easier to use for implementing real SS7 gateway;
999	  eap_sim_db is not anymore used as a file name for GSM authentication
1000	  triplets; instead, it is path to UNIX domain socket that will be used
1001	  to communicate with the external gateway program (e.g., hlr_auc_gw)
1002	* added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
1003	  local information (GSM authentication triplets from a text file and
1004	  hardcoded AKA authentication data); this can be used to test EAP-SIM
1005	  and EAP-AKA
1006	* added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
1007	  to make it possible to test EAP-AKA with real USIM cards (this is
1008	  disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
1009	  to enable this)
1010	* driver_madwifi: added support for getting station RSN IE from
1011	  madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
1012	  broken with earlier change (r1357) in the driver
1013	* changed EAP method registration to use a dynamic list of methods
1014	  instead of a static list generated at build time
1015	* fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
1016	  [Bug 125]
1017	* added ap_max_inactivity configuration parameter
1018
10192006-01-29 - v0.5.1
1020	* driver_test: added better support for multiple APs and STAs by using
1021	  a directory with sockets that include MAC address for each device in
1022	  the name (test_socket=DIR:/tmp/test)
1023	* added support for EAP expanded type (vendor specific EAP methods)
1024
10252005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
1026	* added experimental STAKey handshake implementation for IEEE 802.11e
1027	  direct link setup (DLS); note: this is disabled by default in both
1028	  build and runtime configuration (can be enabled with CONFIG_STAKEY=y
1029	  and stakey=1)
1030	* added support for EAP methods to use callbacks to external programs
1031	  by buffering a pending request and processing it after the EAP method
1032	  is ready to continue
1033	* improved EAP-SIM database interface to allow external request to GSM
1034	  HLR/AuC without blocking hostapd process
1035	* added support for using EAP-SIM pseudonyms and fast re-authentication
1036	* added support for EAP-AKA in the integrated EAP authenticator
1037	* added support for matching EAP identity prefixes (e.g., "1"*) in EAP
1038	  user database to allow EAP-SIM/AKA selection without extra roundtrip
1039	  for EAP-Nak negotiation
1040	* added support for storing EAP user password as NtPasswordHash instead
1041	  of plaintext password when using MSCHAP or MSCHAPv2 for
1042	  authentication (hash:<16-octet hex value>); added nt_password_hash
1043	  tool for hashing password to generate NtPasswordHash
1044
10452005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
1046	* driver_wired: fixed EAPOL sending to optionally use PAE group address
1047	  as the destination instead of supplicant MAC address; this is
1048	  disabled by default, but should be enabled with use_pae_group_addr=1
1049	  in configuration file if the wired interface is used by only one
1050	  device at the time (common switch configuration)
1051	* driver_madwifi: configure driver to use TKIP countermeasures in order
1052	  to get correct behavior (IEEE 802.11 association failing; previously,
1053	  association succeeded, but hostpad forced disassociation immediately)
1054	* driver_madwifi: added support for madwifi-ng
1055
10562005-10-27 - v0.4.6
1057	* added support for replacing user identity from EAP with RADIUS
1058	  User-Name attribute from Access-Accept message, if that is included,
1059	  for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
1060	  tunneled identity into accounting messages when the RADIUS server
1061	  does not support better way of doing this with Class attribute)
1062	* driver_madwifi: fixed EAPOL packet receive for configuration where
1063	  ath# is part of a bridge interface
1064	* added a configuration file and log analyzer script for logwatch
1065	* fixed EAPOL state machine step function to process all state
1066	  transitions before processing new events; this resolves a race
1067	  condition in which EAPOL-Start message could trigger hostapd to send
1068	  two EAP-Response/Identity frames to the authentication server
1069
10702005-09-25 - v0.4.5
1071	* added client CA list to the TLS certificate request in order to make
1072	  it easier for the client to select which certificate to use
1073	* added experimental support for EAP-PSK
1074	* added support for WE-19 (hostap, madwifi)
1075
10762005-08-21 - v0.4.4
1077	* fixed build without CONFIG_RSN_PREAUTH
1078	* fixed FreeBSD build
1079
10802005-06-26 - v0.4.3
1081	* fixed PMKSA caching to copy User-Name and Class attributes so that
1082	  RADIUS accounting gets correct information
1083	* start RADIUS accounting only after successful completion of WPA
1084	  4-Way Handshake if WPA-PSK is used
1085	* fixed PMKSA caching for the case where STA (re)associates without
1086	  first disassociating
1087
10882005-06-12 - v0.4.2
1089	* EAP-PAX is now registered as EAP type 46
1090	* fixed EAP-PAX MAC calculation
1091	* fixed EAP-PAX CK and ICK key derivation
1092	* renamed eap_authenticator configuration variable to eap_server to
1093	  better match with RFC 3748 (EAP) terminology
1094	* driver_test: added support for testing hostapd with wpa_supplicant
1095	  by using test driver interface without any kernel drivers or network
1096	  cards
1097
10982005-05-22 - v0.4.1
1099	* fixed RADIUS server initialization when only auth or acct server
1100	  is configured and the other one is left empty
1101	* driver_madwifi: added support for RADIUS accounting
1102	* driver_madwifi: added preliminary support for compiling against 'BSD'
1103	  branch of madwifi CVS tree
1104	* driver_madwifi: fixed pairwise key removal to allow WPA reauth
1105	  without disassociation
1106	* added support for reading additional certificates from PKCS#12 files
1107	  and adding them to the certificate chain
1108	* fixed RADIUS Class attribute processing to only use Access-Accept
1109	  packets to update Class; previously, other RADIUS authentication
1110	  packets could have cleared Class attribute
1111	* added support for more than one Class attribute in RADIUS packets
1112	* added support for verifying certificate revocation list (CRL) when
1113	  using integrated EAP authenticator for EAP-TLS; new hostapd.conf
1114	  options 'check_crl'; CRL must be included in the ca_cert file for now
1115
11162005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
1117	* added support for including network information into
1118	  EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
1119	  (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
1120	* fixed a bug which caused some RSN pre-authentication cases to use
1121	  freed memory and potentially crash hostapd
1122	* fixed private key loading for cases where passphrase is not set
1123	* added support for sending TLS alerts and aborting authentication
1124	  when receiving a TLS alert
1125	* fixed WPA2 to add PMKSA cache entry when using integrated EAP
1126	  authenticator
1127	* fixed PMKSA caching (EAP authentication was not skipped correctly
1128	  with the new state machine changes from IEEE 802.1X draft)
1129	* added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
1130	  and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
1131	  to be added to .config to include IPv6 support); for RADIUS server,
1132	  radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
1133	  in RADIUS clients file can then use IPv6 format
1134	* added experimental support for EAP-PAX
1135	* replaced hostapd control interface library (hostapd_ctrl.[ch]) with
1136	  the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
1137
11382005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
1139
11402005-01-23 - v0.3.5
1141	* added support for configuring a forced PEAP version based on the
1142	  Phase 1 identity
1143	* fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
1144	  to terminate authentication
1145	* fixed EAP identifier duplicate processing with the new IEEE 802.1X
1146	  draft
1147	* clear accounting data in the driver when starting a new accounting
1148	  session
1149	* driver_madwifi: filter wireless events based on ifindex to allow more
1150	  than one network interface to be used
1151	* fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
1152	  setting if the packet does not pass MIC verification (e.g., due to
1153	  incorrect PSK); previously, message 1/4 was not tried again if an
1154	  invalid message 2/4 was received
1155	* fixed reconfiguration of RADIUS client retransmission timer when
1156	  adding a new message to the pending list; previously, timer was not
1157	  updated at this point and if there was a pending message with long
1158	  time for the next retry, the new message needed to wait that long for
1159	  its first retry, too
1160
11612005-01-09 - v0.3.4
1162	* added support for configuring multiple allowed EAP types for Phase 2
1163	  authentication (EAP-PEAP, EAP-TTLS)
1164	* fixed EAPOL-Start processing to trigger WPA reauthentication
1165	  (previously, only EAPOL authentication was done)
1166
11672005-01-02 - v0.3.3
1168	* added support for EAP-PEAP in the integrated EAP authenticator
1169	* added support for EAP-GTC in the integrated EAP authenticator
1170	* added support for configuring list of EAP methods for Phase 1 so that
1171	  the integrated EAP authenticator can, e.g., use the wildcard entry
1172	  for EAP-TLS and EAP-PEAP
1173	* added support for EAP-TTLS in the integrated EAP authenticator
1174	* added support for EAP-SIM in the integrated EAP authenticator
1175	* added support for using hostapd as a RADIUS authentication server
1176	  with the integrated EAP authenticator taking care of EAP
1177	  authentication (new hostapd.conf options: radius_server_clients and
1178	  radius_server_auth_port); this is not included in default build; use
1179	  CONFIG_RADIUS_SERVER=y in .config to include
1180
11812004-12-19 - v0.3.2
1182	* removed 'daemonize' configuration file option since it has not really
1183	  been used at all for more than year
1184	* driver_madwifi: fixed group key setup and added get_ssid method
1185	* added support for EAP-MSCHAPv2 in the integrated EAP authenticator
1186
11872004-12-12 - v0.3.1
1188	* added support for integrated EAP-TLS authentication (new hostapd.conf
1189	  variables: ca_cert, server_cert, private_key, private_key_passwd);
1190	  this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
1191	  external RADIUS server
1192	* added support for reading PKCS#12 (PFX) files (as a replacement for
1193	  PEM/DER) to get certificate and private key (CONFIG_PKCS12)
1194
11952004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
1196	* added support for Acct-{Input,Output}-Gigawords
1197	* added support for Event-Timestamp (in RADIUS Accounting-Requests)
1198	* added support for RADIUS Authentication Client MIB (RFC2618)
1199	* added support for RADIUS Accounting Client MIB (RFC2620)
1200	* made EAP re-authentication period configurable (eap_reauth_period)
1201	* fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
1202	* fixed EAPOL state machine to stop if STA is removed during
1203	  eapol_sm_step(); this fixes at least one segfault triggering bug with
1204	  IEEE 802.11i pre-authentication
1205	* added support for multiple WPA pre-shared keys (e.g., one for each
1206	  client MAC address or keys shared by a group of clients);
1207	  new hostapd.conf field wpa_psk_file for setting path to a text file
1208	  containing PSKs, see hostapd.wpa_psk for an example
1209	* added support for multiple driver interfaces to allow hostapd to be
1210	  used with other drivers
1211	* added wired authenticator driver interface (driver=wired in
1212	  hostapd.conf, see wired.conf for example configuration)
1213	* added madwifi driver interface (driver=madwifi in hostapd.conf, see
1214	  madwifi.conf for example configuration; Note: include files from
1215	  madwifi project is needed for building and a configuration file,
1216	  .config, needs to be created in hostapd directory with
1217	  CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
1218	  build)
1219	* fixed an alignment issue that could cause SHA-1 to fail on some
1220	  platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
1221	  align variables)
1222	* fixed RADIUS reconnection after an error in sending interim
1223	  accounting packets
1224	* added hostapd control interface for external programs and an example
1225	  CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
1226	* started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
1227	  'hostapd_cli sta <addr>')
1228	* finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
1229	* added support for strict GTK rekeying (wpa_strict_rekey in
1230	  hostapd.conf)
1231	* updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
1232	  (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
1233	  IEEE 802.11F-2003)
1234	* added Prism54 driver interface (driver=prism54 in hostapd.conf;
1235	  note: .config needs to be created in hostapd directory with
1236	  CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
1237	  build)
1238	* dual-licensed hostapd (GPLv2 and BSD licenses)
1239	* fixed RADIUS accounting to generate a new session id for cases where
1240	  a station reassociates without first being complete deauthenticated
1241	* fixed STA disassociation handler to mark next timeout state to
1242	  deauthenticate the station, i.e., skip long wait for inactivity poll
1243	  and extra disassociation, if the STA disassociates without
1244	  deauthenticating
1245	* added integrated EAP authenticator that can be used instead of
1246	  external RADIUS authentication server; currently, only EAP-MD5 is
1247	  supported, so this cannot yet be used for key distribution; the EAP
1248	  method interface is generic, though, so adding new EAP methods should
1249	  be straightforward; new hostapd.conf variables: 'eap_authenticator'
1250	  and 'eap_user_file'; this obsoletes "minimal authentication server"
1251	  ('minimal_eap' in hostapd.conf) which is now removed
1252	* added support for FreeBSD and driver interface for the BSD net80211
1253	  layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
1254	  .config); please note that some of the required kernel mods have not
1255	  yet been committed
1256
12572004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
1258	* fixed some accounting cases where Accounting-Start was sent when
1259	  IEEE 802.1X port was being deauthorized
1260
12612004-06-20 - v0.2.3
1262	* modified RADIUS client to re-connect the socket in case of certain
1263	  error codes that are generated when a network interface state is
1264	  changes (e.g., when IP address changes or the interface is set UP)
1265	* fixed couple of cases where EAPOL state for a station was freed
1266	  twice causing a segfault for hostapd
1267	* fixed couple of bugs in processing WPA deauthentication (freed data
1268	  was used)
1269
12702004-05-31 - v0.2.2
1271	* fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
1272	* fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
1273	  cases where STAs dropped multicast frames as replay attacks
1274	* added support for copying RADIUS Attribute 'Class' from
1275	  authentication messages into accounting messages
1276	* send canned EAP failure if RADIUS server sends Access-Reject without
1277	  EAP message (previously, Supplicant was not notified in this case)
1278	* fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
1279	  not start EAPOL state machines if the STA selected to use WPA-PSK)
1280
12812004-05-06 - v0.2.1
1282	* added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
1283	  - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
1284	    (i.e., IEEE 802.11i/D3.0)
1285	  - supports WPA-only, RSN-only, and mixed WPA/RSN mode
1286	  - both WPA-PSK and WPA-RADIUS/EAP are supported
1287	  - PMKSA caching and pre-authentication
1288	  - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
1289	    wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
1290	    rsn_preauth, rsn_preauth_interfaces
1291	* fixed interim accounting to remove any pending accounting messages
1292	  to the STA before sending a new one
1293
12942004-02-15 - v0.2.0
1295	* added support for Acct-Interim-Interval:
1296	  - draft-ietf-radius-acct-interim-01.txt
1297	  - use Acct-Interim-Interval attribute from Access-Accept if local
1298	    'radius_acct_interim_interval' is not set
1299	  - allow different update intervals for each STA
1300	* fixed event loop to call signal handlers only after returning from
1301	  the real signal handler
1302	* reset sta->timeout_next after successful association to make sure
1303	  that the previously registered inactivity timer will not remove the
1304	  STA immediately (e.g., if STA deauthenticates and re-associates
1305	  before the timer is triggered).
1306	* added new hostapd.conf variable, nas_identifier, that can be used to
1307	  add an optional RADIUS Attribute, NAS-Identifier, into authentication
1308	  and accounting messages
1309	* added support for Accounting-On and Accounting-Off messages
1310	* fixed accounting session handling to send Accounting-Start only once
1311	  per session and not to send Accounting-Stop if the session was not
1312	  initialized properly
1313	* fixed Accounting-Stop statistics in cases where the message was
1314	  previously sent after the kernel entry for the STA (and/or IEEE
1315	  802.1X data) was removed
1316
