434	* fixed EAP-TLS/PEAP/TTLS/FAST server to validate TLS Message Length
435	  correctly; invalid messages could have caused the hostapd process to
436	  terminate before this fix [CVE-2012-4445]
437	* limit number of active wildcard PINs for WPS Registrar to one to avoid
438	  confusing behavior with multiple wildcard PINs
439	* added a workaround for WPS PBC session overlap detection to avoid
440	  interop issues with deployed station implementations that do not
441	  remove active PBC indication from Probe Request frames properly
442	* added support for using SQLite for the eap_user database
443	* added Acct-Session-Id attribute into Access-Request messages
444	* fixed EAPOL frame transmission to non-QoS STAs with nl80211
445	  (do not send QoS frames if the STA did not negotiate use of QoS for
446	  this association)
447
4482012-05-10 - v1.0
449	* Add channel selection support in hostapd. See hostapd.conf.
450	* Add support for IEEE 802.11v Time Advertisement mechanism with UTC
451	  TSF offset. See hostapd.conf for config info.
452	* Delay STA entry removal until Deauth/Disassoc TX status in AP mode.
453	  This allows the driver to use PS buffering of Deauthentication and
454	  Disassociation frames when the STA is in power save sleep. Only
455	  available with drivers that provide TX status events for Deauth/
456	  Disassoc frames (nl80211).
457	* Allow PMKSA caching to be disabled on the Authenticator. See
458	  hostap.conf config parameter disable_pmksa_caching.
459	* atheros: Add support for IEEE 802.11w configuration.
460	* bsd: Add support for setting HT values in IFM_MMASK.
461	* Allow client isolation to be configured with ap_isolate. Client
462	  isolation can be used to prevent low-level bridging of frames
463	  between associated stations in the BSS. By default, this bridging
464	  is allowed.
465	* Allow coexistance of HT BSSes with WEP/TKIP BSSes.
466	* Add require_ht config parameter, which can be used to configure
467	  hostapd to reject association with any station that does not support
468	  HT PHY.
469	* Add support for writing debug log to a file using "-f" option. Also
470	  add relog CLI command to re-open the log file.
471	* Add bridge handling for WDS STA interfaces. By default they are
472	  added to the configured bridge of the AP interface (if present),
473	  but the user can also specify a separate bridge using cli command
474	  wds_bridge.
475	* hostapd_cli:
476	  - Add wds_bridge command for specifying bridge for WDS STA
477	    interfaces.
478	  - Add relog command for reopening log file.
479	  - Send AP-STA-DISCONNECTED event when an AP disconnects a station
480	    due to inactivity.
481	  - Add wps_config ctrl_interface command for configuring AP. This
482	    command can be used to configure the AP using the internal WPS
483	    registrar. It works in the same way as new AP settings received
484	    from an ER.
485	  - Many WPS/WPS ER commands - see WPS/WPS ER sections for details.
486	  - Add command get version, that returns hostapd version string.
487	* WNM: Add BSS Transition Management Request for ESS Disassoc Imminent.
488	  Use hostapd_cli ess_disassoc (STA addr) (URL) to send the
489	  notification to the STA.
490	* Allow AP mode to disconnect STAs based on low ACK condition (when
491	  the data connection is not working properly, e.g., due to the STA
492	  going outside the range of the AP). Disabled by default, enable by
493	  config option disassoc_low_ack.
494	* Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad
495	  config file.
496	* WPS:
497	  - Send AP Settings as a wrapped Credential attribute to ctrl_iface
498	    in WPS-NEW-AP-SETTINGS.
499	  - Dispatch more WPS events through hostapd ctrl_iface.
500	  - Add mechanism for indicating non-standard WPS errors.
501	  - Change concurrent radio AP to use only one WPS UPnP instance.
502	  - Add wps_check_pin command for processing PIN from user input.
503	    UIs can use this command to process a PIN entered by a user and to
504	    validate the checksum digit (if present).
505	  - Add hostap_cli get_config command to display current AP config.
506	  - Add new hostapd_cli command, wps_ap_pin, to manage AP PIN at
507	    runtime and support dynamic AP PIN management.
508	  - Disable AP PIN after 10 consecutive failures. Slow down attacks
509	    on failures up to 10.
510	  - Allow AP to start in Enrollee mode without AP PIN for probing,
511	    to be compatible with Windows 7.
512	  - Add Config Error into WPS-FAIL events to provide more info
513	    to the user on how to resolve the issue.
514	  - When controlling multiple interfaces:
515	     - apply WPS commands to all interfaces configured to use WPS
516	     - apply WPS config changes to all interfaces that use WPS
517	     - when an attack is detected on any interface, disable AP PIN on
518	       all interfaces
519	* WPS ER:
520	  - Show SetSelectedRegistrar events as ctrl_iface events.
521	  - Add special AP Setup Locked mode to allow read only ER.
522	    ap_setup_locked=2 can now be used to enable a special mode where
523	    WPS ER can learn the current AP settings, but cannot change them.
524	* WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2)
525	  - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool
526	    for testing protocol extensibility.
527	  - Add build option CONFIG_WPS_STRICT to allow disabling of WPS
528	    workarounds.
529	  - Add support for AuthorizedMACs attribute.
530	* TDLS:
531	  - Allow TDLS use or TDLS channel switching in the BSS to be
532	    prohibited in the BSS, using config params tdls_prohibit and
533	    tdls_prohibit_chan_switch.
534	* EAP server: Add support for configuring fragment size (see
535	  fragment_size in hostapd.conf).
536	* wlantest: Add a tool wlantest for IEEE802.11 protocol testing.
537	  wlantest can be used to capture frames from a monitor interface
538	  for realtime capturing or from pcap files for offline analysis.
539	* Interworking: Support added for 802.11u. Enable in .config with
540	  CONFIG_INTERWORKING. See hostapd.conf for config parameters for
541	  interworking.
542	* Android: Add build and runtime support for Android hostapd.
543	* Add a new debug message level for excessive information. Use
544	  -ddd to enable.
545	* TLS: Add support for tls_disable_time_checks=1 in client mode.
546	* Internal TLS:
547	  - Add support for TLS v1.1 (RFC 4346). Enable with build parameter
548	    CONFIG_TLSV11.
549	  - Add domainComponent parser for X.509 names
550	* Reorder some IEs to get closer to IEEE 802.11 standard. Move
551	  WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames.
552	  Move HT IEs to be later in (Re)Assoc Resp.
553	* Many bugfixes.
554
5552010-04-18 - v0.7.2
556	* fix WPS internal Registrar use when an external Registrar is also
557	  active
558	* bsd: Cleaned up driver wrapper and added various low-level
559	  configuration options
560	* TNC: fixed issues with fragmentation
561	* EAP-TNC: add Flags field into fragment acknowledgement (needed to
562	  interoperate with other implementations; may potentially breaks
563	  compatibility with older wpa_supplicant/hostapd versions)
564	* cleaned up driver wrapper API for multi-BSS operations
565	* nl80211: fix multi-BSS and VLAN operations
566	* fix number of issues with IEEE 802.11r/FT; this version is not
567	  backwards compatible with old versions
568	* add SA Query Request processing in AP mode (IEEE 802.11w)
569	* fix IGTK PN in group rekeying (IEEE 802.11w)
570	* fix WPS PBC session overlap detection to use correct attribute
571	* hostapd_notif_Assoc() can now be called with all IEs to simplify
572	  driver wrappers
573	* work around interoperability issue with some WPS External Registrar
574	  implementations
575	* nl80211: fix WPS IE update
576	* hostapd_cli: add support for action script operations (run a script
577	  on hostapd events)
578	* fix DH padding with internal crypto code (mainly, for WPS)
579	* fix WPS association with both WPS IE and WPA/RSN IE present with
580	  driver wrappers that use hostapd MLME (e.g., nl80211)
581
5822010-01-16 - v0.7.1
583	* cleaned up driver wrapper API (struct wpa_driver_ops); the new API
584	  is not fully backwards compatible, so out-of-tree driver wrappers
585	  will need modifications
586	* cleaned up various module interfaces
587	* merge hostapd and wpa_supplicant developers' documentation into a
588	  single document
589	* fixed HT Capabilities IE with nl80211 drivers
590	* moved generic AP functionality code into src/ap
591	* WPS: handle Selected Registrar as union of info from all Registrars

594	  allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y)
595	* EAP-FAST server: piggyback Phase 2 start with the end of Phase 1
596	* WPS: add support for dynamically selecting whether to provision the
597	  PSK as an ASCII passphrase or PSK
598	* added support for WDS (4-address frame) mode with per-station virtual
599	  interfaces (wds_sta=1 in config file; only supported with
600	  driver=nl80211 for now)
601	* fixed WPS Probe Request processing to handle missing required
602	  attribute
603	* fixed PKCS#12 use with OpenSSL 1.0.0
604	* detect bridge interface automatically so that bridge parameter in
605	  hostapd.conf becomes optional (though, it may now be used to
606	  automatically add then WLAN interface into a bridge with
607	  driver=nl80211)
608
6092009-11-21 - v0.7.0
610	* increased hostapd_cli ping interval to 5 seconds and made this
611	  configurable with a new command line options (-G<seconds>)
612	* driver_nl80211: use Linux socket filter to improve performance
613	* added support for external Registrars with WPS (UPnP transport)
614	* 802.11n: scan for overlapping BSSes before starting 20/40 MHz channel
615	* driver_nl80211: fixed STA accounting data collection (TX/RX bytes
616	  reported correctly; TX/RX packets not yet available from kernel)
617	* added support for WPS USBA out-of-band mechanism with USB Flash
618	  Drives (UFD) (CONFIG_WPS_UFD=y)
619	* fixed EAPOL/EAP reauthentication when using an external RADIUS
620	  authentication server
621	* fixed TNC with EAP-TTLS
622	* fixed IEEE 802.11r key derivation function to match with the standard
623	  (note: this breaks interoperability with previous version) [Bug 303]
624	* fixed SHA-256 based key derivation function to match with the
625	  standard when using CCMP (for IEEE 802.11r and IEEE 802.11w)
626	  (note: this breaks interoperability with previous version) [Bug 307]
627	* added number of code size optimizations to remove unnecessary
628	  functionality from the program binary based on build configuration
629	  (part of this automatic; part configurable with CONFIG_NO_* build
630	  options)
631	* use shared driver wrapper files with wpa_supplicant
632	* driver_nl80211: multiple updates to provide support for new Linux
633	  nl80211/mac80211 functionality
634	* updated management frame protection to use IEEE Std 802.11w-2009
635	* fixed number of small WPS issues and added workarounds to
636	  interoperate with common deployed broken implementations
637	* added some IEEE 802.11n co-existence rules to disable 40 MHz channels
638	  or modify primary/secondary channels if needed based on neighboring
639	  networks
640	* added support for NFC out-of-band mechanism with WPS
641	* added preliminary support for IEEE 802.11r RIC processing
642
6432009-01-06 - v0.6.7
644	* added support for Wi-Fi Protected Setup (WPS)
645	  (hostapd can now be configured to act as an integrated WPS Registrar
646	  and provision credentials for WPS Enrollees using PIN and PBC
647	  methods; external wireless Registrar can configure the AP, but
648	  external WLAN Manager Registrars are not supported); WPS support can
649	  be enabled by adding CONFIG_WPS=y into .config and setting the
650	  runtime configuration variables in hostapd.conf (see WPS section in
651	  the example configuration file); new hostapd_cli commands wps_pin and
652	  wps_pbc are used to configure WPS negotiation; see README-WPS for
653	  more details
654	* added IEEE 802.11n HT capability configuration (ht_capab)
655	* added support for generating Country IE based on nl80211 regulatory
656	  information (added if ieee80211d=1 in configuration)
657	* fixed WEP authentication (both Open System and Shared Key) with
658	  mac80211
659	* added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
660	* added support for using driver_test over UDP socket
661	* changed EAP-GPSK to use the IANA assigned EAP method type 51
662	* updated management frame protection to use IEEE 802.11w/D7.0
663	* fixed retransmission of EAP requests if no response is received
664
6652008-11-23 - v0.6.6
666	* added a new configuration option, wpa_ptk_rekey, that can be used to
667	  enforce frequent PTK rekeying, e.g., to mitigate some attacks against
668	  TKIP deficiencies
669	* updated OpenSSL code for EAP-FAST to use an updated version of the
670	  session ticket overriding API that was included into the upstream
671	  OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
672	  needed with that version anymore)
673	* changed channel flags configuration to read the information from
674	  the driver (e.g., via driver_nl80211 when using mac80211) instead of
675	  using hostapd as the source of the regulatory information (i.e.,
676	  information from CRDA is now used with mac80211); this allows 5 GHz
677	  channels to be used with hostapd (if allowed in the current
678	  regulatory domain)
679	* fixed EAP-TLS message processing for the last TLS message if it is
680	  large enough to require fragmentation (e.g., if a large Session
681	  Ticket data is included)
682	* fixed listen interval configuration for nl80211 drivers
683
6842008-11-01 - v0.6.5
685	* added support for SHA-256 as X.509 certificate digest when using the
686	  internal X.509/TLSv1 implementation
687	* fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer
688	  identity lengths)
689	* fixed internal TLSv1 implementation for abbreviated handshake (used
690	  by EAP-FAST server)
691	* added support for setting VLAN ID for STAs based on local MAC ACL
692	  (accept_mac_file) as an alternative for RADIUS server-based
693	  configuration
694	* updated management frame protection to use IEEE 802.11w/D6.0
695	  (adds a new association ping to protect against unauthenticated
696	  authenticate or (re)associate request frames dropping association)
697	* added support for using SHA256-based stronger key derivation for WPA2
698	  (IEEE 802.11w)
699	* added new "driver wrapper" for RADIUS-only configuration
700	  (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config)
701	* fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2)
702	  is enabled in configuration
703	* changed EAP-FAST configuration to use separate fields for A-ID and
704	  A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed
705	  16-octet len binary value for better interoperability with some peer
706	  implementations; eap_fast_a_id is now configured as a hex string
707	* driver_nl80211: Updated to match the current Linux mac80211 AP mode
708	  configuration (wireless-testing.git and Linux kernel releases
709	  starting from 2.6.29)
710
7112008-08-10 - v0.6.4
712	* added peer identity into EAP-FAST PAC-Opaque and skip Phase 2
713	  Identity Request if identity is already known
714	* added support for EAP Sequences in EAP-FAST Phase 2
715	* added support for EAP-TNC (Trusted Network Connect)
716	  (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST
717	  changes needed to run two methods in sequence (IF-T) and the IF-IMV
718	  and IF-TNCCS interfaces from TNCS)
719	* added support for optional cryptobinding with PEAPv0
720	* added fragmentation support for EAP-TNC
721	* added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled)
722	  data
723	* added support for opportunistic key caching (OKC)
724
7252008-02-22 - v0.6.3
726	* fixed Reassociation Response callback processing when using internal
727	  MLME (driver_{hostap,nl80211,test}.c)
728	* updated FT support to use the latest draft, IEEE 802.11r/D9.0
729	* copy optional Proxy-State attributes into RADIUS response when acting
730	  as a RADIUS authentication server
731	* fixed EAPOL state machine to handle a case in which no response is
732	  received from the RADIUS authentication server; previous version
733	  could have triggered a crash in some cases after a timeout
734	* fixed EAP-SIM/AKA realm processing to allow decorated usernames to
735	  be used
736	* added a workaround for EAP-SIM/AKA peers that include incorrect null
737	  termination in the username
738	* fixed EAP-SIM/AKA protected result indication to include AT_COUNTER
739	  attribute in notification messages only when using fast
740	  reauthentication
741	* fixed EAP-SIM Start response processing for fast reauthentication
742	  case
743	* added support for pending EAP processing in EAP-{PEAP,TTLS,FAST}
744	  phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method
745
7462008-01-01 - v0.6.2
747	* fixed EAP-SIM and EAP-AKA message parser to validate attribute
748	  lengths properly to avoid potential crash caused by invalid messages
749	* added data structure for storing allocated buffers (struct wpabuf);
750	  this does not affect hostapd usage, but many of the APIs changed
751	  and various interfaces (e.g., EAP) is not compatible with old
752	  versions
753	* added support for protecting EAP-AKA/Identity messages with
754	  AT_CHECKCODE (optional feature in RFC 4187)
755	* added support for protected result indication with AT_RESULT_IND for
756	  EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1)
757	* added support for configuring EAP-TTLS phase 2 non-EAP methods in
758	  EAP server configuration; previously all four were enabled for every
759	  phase 2 user, now all four are disabled by default and need to be
760	  enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP,
761	  TTLS-MSCHAPV2
762	* removed old debug printing mechanism and the related 'debug'
763	  parameter in the configuration file; debug verbosity is now set with
764	  -d (or -dd) command line arguments
765	* added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
766	  only shared key/password authentication is supported in this version
767
7682007-11-24 - v0.6.1
769	* added experimental, integrated TLSv1 server implementation with the
770	  needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
771	  setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
772	  .config); this can be useful, e.g., if the target system does not
773	  have a suitable TLS library and a minimal code size is required
774	* added support for EAP-FAST server method to the integrated EAP
775	  server
776	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
777	  draft (draft-ietf-emu-eap-gpsk-07.txt)
778	* added a new configuration parameter, rsn_pairwise, to allow different
779	  pairwise cipher suites to be enabled for WPA and RSN/WPA2
780	  (note: if wpa_pairwise differs from rsn_pairwise, the driver will
781	  either need to support this or will have to use the WPA/RSN IEs from
782	  hostapd; currently, the included madwifi and bsd driver interfaces do
783	  not have support for this)
784	* updated FT support to use the latest draft, IEEE 802.11r/D8.0
785
7862007-05-28 - v0.6.0
787	* added experimental IEEE 802.11r/D6.0 support
788	* updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
789	* updated EAP-PSK to use the IANA-allocated EAP type 47
790	* fixed EAP-PSK bit ordering of the Flags field
791	* fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
792	  by reading wpa_psk_file [Bug 181]
793	* fixed EAP-TTLS AVP parser processing for too short AVP lengths
794	* fixed IPv6 connection to RADIUS accounting server
795	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
796	  draft (draft-ietf-emu-eap-gpsk-04.txt)
797	* hlr_auc_gw: read GSM triplet file into memory and rotate through the
798	  entries instead of only using the same three triplets every time
799	  (this does not work properly with tests using multiple clients, but
800	  provides bit better triplet data for testing a single client; anyway,
801	  if a better quality triplets are needed, GSM-Milenage should be used
802	  instead of hardcoded triplet file)
803	* fixed EAP-MSCHAPv2 server to use a space between S and M parameters
804	  in Success Request [Bug 203]
805	* added support for sending EAP-AKA Notifications in error cases
806	* updated to use IEEE 802.11w/D2.0 for management frame protection
807	  (still experimental)
808	* RADIUS server: added support for processing duplicate messages
809	  (retransmissions from RADIUS client) by replying with the previous
810	  reply
811
8122006-11-24 - v0.5.6
813	* added support for configuring and controlling multiple BSSes per
814	  radio interface (bss=<ifname> in hostapd.conf); this is only
815	  available with Devicescape and test driver interfaces
816	* fixed PMKSA cache update in the end of successful RSN
817	  pre-authentication
818	* added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
819	  for each STA based on RADIUS Access-Accept attributes); this requires
820	  VLAN support from the kernel driver/802.11 stack and this is
821	  currently only available with Devicescape and test driver interfaces
822	* driver_madwifi: fixed configuration of unencrypted modes (plaintext
823	  and IEEE 802.1X without WEP)
824	* removed STAKey handshake since PeerKey handshake has replaced it in
825	  IEEE 802.11ma and there are no known deployments of STAKey
826	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
827	  draft (draft-ietf-emu-eap-gpsk-01.txt)
828	* added preliminary implementation of IEEE 802.11w/D1.0 (management
829	  frame protection)
830	  (Note: this requires driver support to work properly.)
831	  (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
832	* hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
833	* hlr_auc_gw: added support for reading per-IMSI Milenage keys and
834	  parameters from a text file to make it possible to implement proper
835	  GSM/UMTS authentication server for multiple SIM/USIM cards using
836	  EAP-SIM/EAP-AKA
837	* fixed session timeout processing with drivers that do not use
838	  ieee802_11.c (e.g., madwifi)
839
8402006-08-27 - v0.5.5
841	* added 'hostapd_cli new_sta <addr>' command for adding a new STA into
842	  hostapd (e.g., to initialize wired network authentication based on an
843	  external signal)
844	* fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
845	  using WPA2 even if PMKSA caching is not used
846	* added -P<pid file> argument for hostapd to write the current process
847	  id into a file
848	* added support for RADIUS Authentication Server MIB (RFC 2619)
849
8502006-06-20 - v0.5.4
851	* fixed nt_password_hash build [Bug 144]
852	* added PeerKey handshake implementation for IEEE 802.11e
853	  direct link setup (DLS) to replace STAKey handshake
854	* added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
855	  draft-clancy-emu-eap-shared-secret-00.txt)
856	* fixed a segmentation fault when RSN pre-authentication was completed
857	  successfully [Bug 152]
858
8592006-04-27 - v0.5.3
860	* do not build nt_password_hash and hlr_auc_gw by default to avoid
861	  requiring a TLS library for a successful build; these programs can be
862	  build with 'make nt_password_hash' and 'make hlr_auc_gw'
863	* added a new configuration option, eapol_version, that can be used to
864	  set EAPOL version to 1 (default is 2) to work around broken client
865	  implementations that drop EAPOL frames which use version number 2
866	  [Bug 89]
867	* added support for EAP-SAKE (no EAP method number allocated yet, so
868	  this is using the same experimental type 255 as EAP-PSK)
869	* fixed EAP-MSCHAPv2 message length validation
870
8712006-03-19 - v0.5.2
872	* fixed stdarg use in hostapd_logger(): if both stdout and syslog
873	  logging was enabled, hostapd could trigger a segmentation fault in
874	  vsyslog on some CPU -- C library combinations
875	* moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
876	  program to make it easier to use for implementing real SS7 gateway;
877	  eap_sim_db is not anymore used as a file name for GSM authentication
878	  triplets; instead, it is path to UNIX domain socket that will be used
879	  to communicate with the external gateway program (e.g., hlr_auc_gw)
880	* added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
881	  local information (GSM authentication triplets from a text file and
882	  hardcoded AKA authentication data); this can be used to test EAP-SIM
883	  and EAP-AKA
884	* added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
885	  to make it possible to test EAP-AKA with real USIM cards (this is
886	  disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
887	  to enable this)
888	* driver_madwifi: added support for getting station RSN IE from
889	  madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
890	  broken with earlier change (r1357) in the driver
891	* changed EAP method registration to use a dynamic list of methods
892	  instead of a static list generated at build time
893	* fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
894	  [Bug 125]
895	* added ap_max_inactivity configuration parameter
896
8972006-01-29 - v0.5.1
898	* driver_test: added better support for multiple APs and STAs by using
899	  a directory with sockets that include MAC address for each device in
900	  the name (test_socket=DIR:/tmp/test)
901	* added support for EAP expanded type (vendor specific EAP methods)
902
9032005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
904	* added experimental STAKey handshake implementation for IEEE 802.11e
905	  direct link setup (DLS); note: this is disabled by default in both
906	  build and runtime configuration (can be enabled with CONFIG_STAKEY=y
907	  and stakey=1)
908	* added support for EAP methods to use callbacks to external programs
909	  by buffering a pending request and processing it after the EAP method
910	  is ready to continue
911	* improved EAP-SIM database interface to allow external request to GSM
912	  HLR/AuC without blocking hostapd process
913	* added support for using EAP-SIM pseudonyms and fast re-authentication
914	* added support for EAP-AKA in the integrated EAP authenticator
915	* added support for matching EAP identity prefixes (e.g., "1"*) in EAP
916	  user database to allow EAP-SIM/AKA selection without extra roundtrip
917	  for EAP-Nak negotiation
918	* added support for storing EAP user password as NtPasswordHash instead
919	  of plaintext password when using MSCHAP or MSCHAPv2 for
920	  authentication (hash:<16-octet hex value>); added nt_password_hash
921	  tool for hashing password to generate NtPasswordHash
922
9232005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
924	* driver_wired: fixed EAPOL sending to optionally use PAE group address
925	  as the destination instead of supplicant MAC address; this is
926	  disabled by default, but should be enabled with use_pae_group_addr=1
927	  in configuration file if the wired interface is used by only one
928	  device at the time (common switch configuration)
929	* driver_madwifi: configure driver to use TKIP countermeasures in order
930	  to get correct behavior (IEEE 802.11 association failing; previously,
931	  association succeeded, but hostpad forced disassociation immediately)
932	* driver_madwifi: added support for madwifi-ng
933
9342005-10-27 - v0.4.6
935	* added support for replacing user identity from EAP with RADIUS
936	  User-Name attribute from Access-Accept message, if that is included,
937	  for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
938	  tunneled identity into accounting messages when the RADIUS server
939	  does not support better way of doing this with Class attribute)
940	* driver_madwifi: fixed EAPOL packet receive for configuration where
941	  ath# is part of a bridge interface
942	* added a configuration file and log analyzer script for logwatch
943	* fixed EAPOL state machine step function to process all state
944	  transitions before processing new events; this resolves a race
945	  condition in which EAPOL-Start message could trigger hostapd to send
946	  two EAP-Response/Identity frames to the authentication server
947
9482005-09-25 - v0.4.5
949	* added client CA list to the TLS certificate request in order to make
950	  it easier for the client to select which certificate to use
951	* added experimental support for EAP-PSK
952	* added support for WE-19 (hostap, madwifi)
953
9542005-08-21 - v0.4.4
955	* fixed build without CONFIG_RSN_PREAUTH
956	* fixed FreeBSD build
957
9582005-06-26 - v0.4.3
959	* fixed PMKSA caching to copy User-Name and Class attributes so that
960	  RADIUS accounting gets correct information
961	* start RADIUS accounting only after successful completion of WPA
962	  4-Way Handshake if WPA-PSK is used
963	* fixed PMKSA caching for the case where STA (re)associates without
964	  first disassociating
965
9662005-06-12 - v0.4.2
967	* EAP-PAX is now registered as EAP type 46
968	* fixed EAP-PAX MAC calculation
969	* fixed EAP-PAX CK and ICK key derivation
970	* renamed eap_authenticator configuration variable to eap_server to
971	  better match with RFC 3748 (EAP) terminology
972	* driver_test: added support for testing hostapd with wpa_supplicant
973	  by using test driver interface without any kernel drivers or network
974	  cards
975
9762005-05-22 - v0.4.1
977	* fixed RADIUS server initialization when only auth or acct server
978	  is configured and the other one is left empty
979	* driver_madwifi: added support for RADIUS accounting
980	* driver_madwifi: added preliminary support for compiling against 'BSD'
981	  branch of madwifi CVS tree
982	* driver_madwifi: fixed pairwise key removal to allow WPA reauth
983	  without disassociation
984	* added support for reading additional certificates from PKCS#12 files
985	  and adding them to the certificate chain
986	* fixed RADIUS Class attribute processing to only use Access-Accept
987	  packets to update Class; previously, other RADIUS authentication
988	  packets could have cleared Class attribute
989	* added support for more than one Class attribute in RADIUS packets
990	* added support for verifying certificate revocation list (CRL) when
991	  using integrated EAP authenticator for EAP-TLS; new hostapd.conf
992	  options 'check_crl'; CRL must be included in the ca_cert file for now
993
9942005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
995	* added support for including network information into
996	  EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
997	  (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
998	* fixed a bug which caused some RSN pre-authentication cases to use
999	  freed memory and potentially crash hostapd
1000	* fixed private key loading for cases where passphrase is not set
1001	* added support for sending TLS alerts and aborting authentication
1002	  when receiving a TLS alert
1003	* fixed WPA2 to add PMKSA cache entry when using integrated EAP
1004	  authenticator
1005	* fixed PMKSA caching (EAP authentication was not skipped correctly
1006	  with the new state machine changes from IEEE 802.1X draft)
1007	* added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
1008	  and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
1009	  to be added to .config to include IPv6 support); for RADIUS server,
1010	  radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
1011	  in RADIUS clients file can then use IPv6 format
1012	* added experimental support for EAP-PAX
1013	* replaced hostapd control interface library (hostapd_ctrl.[ch]) with
1014	  the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
1015
10162005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
1017
10182005-01-23 - v0.3.5
1019	* added support for configuring a forced PEAP version based on the
1020	  Phase 1 identity
1021	* fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
1022	  to terminate authentication
1023	* fixed EAP identifier duplicate processing with the new IEEE 802.1X
1024	  draft
1025	* clear accounting data in the driver when starting a new accounting
1026	  session
1027	* driver_madwifi: filter wireless events based on ifindex to allow more
1028	  than one network interface to be used
1029	* fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
1030	  setting if the packet does not pass MIC verification (e.g., due to
1031	  incorrect PSK); previously, message 1/4 was not tried again if an
1032	  invalid message 2/4 was received
1033	* fixed reconfiguration of RADIUS client retransmission timer when
1034	  adding a new message to the pending list; previously, timer was not
1035	  updated at this point and if there was a pending message with long
1036	  time for the next retry, the new message needed to wait that long for
1037	  its first retry, too
1038
10392005-01-09 - v0.3.4
1040	* added support for configuring multiple allowed EAP types for Phase 2
1041	  authentication (EAP-PEAP, EAP-TTLS)
1042	* fixed EAPOL-Start processing to trigger WPA reauthentication
1043	  (previously, only EAPOL authentication was done)
1044
10452005-01-02 - v0.3.3
1046	* added support for EAP-PEAP in the integrated EAP authenticator
1047	* added support for EAP-GTC in the integrated EAP authenticator
1048	* added support for configuring list of EAP methods for Phase 1 so that
1049	  the integrated EAP authenticator can, e.g., use the wildcard entry
1050	  for EAP-TLS and EAP-PEAP
1051	* added support for EAP-TTLS in the integrated EAP authenticator
1052	* added support for EAP-SIM in the integrated EAP authenticator
1053	* added support for using hostapd as a RADIUS authentication server
1054	  with the integrated EAP authenticator taking care of EAP
1055	  authentication (new hostapd.conf options: radius_server_clients and
1056	  radius_server_auth_port); this is not included in default build; use
1057	  CONFIG_RADIUS_SERVER=y in .config to include
1058
10592004-12-19 - v0.3.2
1060	* removed 'daemonize' configuration file option since it has not really
1061	  been used at all for more than year
1062	* driver_madwifi: fixed group key setup and added get_ssid method
1063	* added support for EAP-MSCHAPv2 in the integrated EAP authenticator
1064
10652004-12-12 - v0.3.1
1066	* added support for integrated EAP-TLS authentication (new hostapd.conf
1067	  variables: ca_cert, server_cert, private_key, private_key_passwd);
1068	  this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
1069	  external RADIUS server
1070	* added support for reading PKCS#12 (PFX) files (as a replacement for
1071	  PEM/DER) to get certificate and private key (CONFIG_PKCS12)
1072
10732004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
1074	* added support for Acct-{Input,Output}-Gigawords
1075	* added support for Event-Timestamp (in RADIUS Accounting-Requests)
1076	* added support for RADIUS Authentication Client MIB (RFC2618)
1077	* added support for RADIUS Accounting Client MIB (RFC2620)
1078	* made EAP re-authentication period configurable (eap_reauth_period)
1079	* fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
1080	* fixed EAPOL state machine to stop if STA is removed during
1081	  eapol_sm_step(); this fixes at least one segfault triggering bug with
1082	  IEEE 802.11i pre-authentication
1083	* added support for multiple WPA pre-shared keys (e.g., one for each
1084	  client MAC address or keys shared by a group of clients);
1085	  new hostapd.conf field wpa_psk_file for setting path to a text file
1086	  containing PSKs, see hostapd.wpa_psk for an example
1087	* added support for multiple driver interfaces to allow hostapd to be
1088	  used with other drivers
1089	* added wired authenticator driver interface (driver=wired in
1090	  hostapd.conf, see wired.conf for example configuration)
1091	* added madwifi driver interface (driver=madwifi in hostapd.conf, see
1092	  madwifi.conf for example configuration; Note: include files from
1093	  madwifi project is needed for building and a configuration file,
1094	  .config, needs to be created in hostapd directory with
1095	  CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
1096	  build)
1097	* fixed an alignment issue that could cause SHA-1 to fail on some
1098	  platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
1099	  align variables)
1100	* fixed RADIUS reconnection after an error in sending interim
1101	  accounting packets
1102	* added hostapd control interface for external programs and an example
1103	  CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
1104	* started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
1105	  'hostapd_cli sta <addr>')
1106	* finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
1107	* added support for strict GTK rekeying (wpa_strict_rekey in
1108	  hostapd.conf)
1109	* updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
1110	  (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
1111	  IEEE 802.11F-2003)
1112	* added Prism54 driver interface (driver=prism54 in hostapd.conf;
1113	  note: .config needs to be created in hostapd directory with
1114	  CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
1115	  build)
1116	* dual-licensed hostapd (GPLv2 and BSD licenses)
1117	* fixed RADIUS accounting to generate a new session id for cases where
1118	  a station reassociates without first being complete deauthenticated
1119	* fixed STA disassociation handler to mark next timeout state to
1120	  deauthenticate the station, i.e., skip long wait for inactivity poll
1121	  and extra disassociation, if the STA disassociates without
1122	  deauthenticating
1123	* added integrated EAP authenticator that can be used instead of
1124	  external RADIUS authentication server; currently, only EAP-MD5 is
1125	  supported, so this cannot yet be used for key distribution; the EAP
1126	  method interface is generic, though, so adding new EAP methods should
1127	  be straightforward; new hostapd.conf variables: 'eap_authenticator'
1128	  and 'eap_user_file'; this obsoletes "minimal authentication server"
1129	  ('minimal_eap' in hostapd.conf) which is now removed
1130	* added support for FreeBSD and driver interface for the BSD net80211
1131	  layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
1132	  .config); please note that some of the required kernel mods have not
1133	  yet been committed
1134
11352004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
1136	* fixed some accounting cases where Accounting-Start was sent when
1137	  IEEE 802.1X port was being deauthorized
1138
11392004-06-20 - v0.2.3
1140	* modified RADIUS client to re-connect the socket in case of certain
1141	  error codes that are generated when a network interface state is
1142	  changes (e.g., when IP address changes or the interface is set UP)
1143	* fixed couple of cases where EAPOL state for a station was freed
1144	  twice causing a segfault for hostapd
1145	* fixed couple of bugs in processing WPA deauthentication (freed data
1146	  was used)
1147
11482004-05-31 - v0.2.2
1149	* fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
1150	* fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
1151	  cases where STAs dropped multicast frames as replay attacks
1152	* added support for copying RADIUS Attribute 'Class' from
1153	  authentication messages into accounting messages
1154	* send canned EAP failure if RADIUS server sends Access-Reject without
1155	  EAP message (previously, Supplicant was not notified in this case)
1156	* fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
1157	  not start EAPOL state machines if the STA selected to use WPA-PSK)
1158
11592004-05-06 - v0.2.1
1160	* added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
1161	  - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
1162	    (i.e., IEEE 802.11i/D3.0)
1163	  - supports WPA-only, RSN-only, and mixed WPA/RSN mode
1164	  - both WPA-PSK and WPA-RADIUS/EAP are supported
1165	  - PMKSA caching and pre-authentication
1166	  - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
1167	    wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
1168	    rsn_preauth, rsn_preauth_interfaces
1169	* fixed interim accounting to remove any pending accounting messages
1170	  to the STA before sending a new one
1171
11722004-02-15 - v0.2.0
1173	* added support for Acct-Interim-Interval:
1174	  - draft-ietf-radius-acct-interim-01.txt
1175	  - use Acct-Interim-Interval attribute from Access-Accept if local
1176	    'radius_acct_interim_interval' is not set
1177	  - allow different update intervals for each STA
1178	* fixed event loop to call signal handlers only after returning from
1179	  the real signal handler
1180	* reset sta->timeout_next after successful association to make sure
1181	  that the previously registered inactivity timer will not remove the
1182	  STA immediately (e.g., if STA deauthenticates and re-associates
1183	  before the timer is triggered).
1184	* added new hostapd.conf variable, nas_identifier, that can be used to
1185	  add an optional RADIUS Attribute, NAS-Identifier, into authentication
1186	  and accounting messages
1187	* added support for Accounting-On and Accounting-Off messages
1188	* fixed accounting session handling to send Accounting-Start only once
1189	  per session and not to send Accounting-Stop if the session was not
1190	  initialized properly
1191	* fixed Accounting-Stop statistics in cases where the message was
1192	  previously sent after the kernel entry for the STA (and/or IEEE
1193	  802.1X data) was removed
1194
1195
1196Note:
1197
1198Older changes up to and including v0.1.0 are included in the ChangeLog
1199of the Host AP driver.
