398	  This allows the driver to use PS buffering of Deauthentication and
399	  Disassociation frames when the STA is in power save sleep. Only
400	  available with drivers that provide TX status events for Deauth/
401	  Disassoc frames (nl80211).

405	* bsd: Add support for setting HT values in IFM_MMASK.
406	* Allow client isolation to be configured with ap_isolate. Client
407	  isolation can be used to prevent low-level bridging of frames
408	  between associated stations in the BSS. By default, this bridging
409	  is allowed.
410	* Allow coexistance of HT BSSes with WEP/TKIP BSSes.
411	* Add require_ht config parameter, which can be used to configure
412	  hostapd to reject association with any station that does not support
413	  HT PHY.
414	* Add support for writing debug log to a file using "-f" option. Also
415	  add relog CLI command to re-open the log file.
416	* Add bridge handling for WDS STA interfaces. By default they are
417	  added to the configured bridge of the AP interface (if present),
418	  but the user can also specify a separate bridge using cli command
419	  wds_bridge.
420	* hostapd_cli:
421	  - Add wds_bridge command for specifying bridge for WDS STA
422	    interfaces.
423	  - Add relog command for reopening log file.
424	  - Send AP-STA-DISCONNECTED event when an AP disconnects a station
425	    due to inactivity.
426	  - Add wps_config ctrl_interface command for configuring AP. This
427	    command can be used to configure the AP using the internal WPS
428	    registrar. It works in the same way as new AP settings received
429	    from an ER.
430	  - Many WPS/WPS ER commands - see WPS/WPS ER sections for details.
431	  - Add command get version, that returns hostapd version string.
432	* WNM: Add BSS Transition Management Request for ESS Disassoc Imminent.
433	  Use hostapd_cli ess_disassoc (STA addr) (URL) to send the
434	  notification to the STA.
435	* Allow AP mode to disconnect STAs based on low ACK condition (when
436	  the data connection is not working properly, e.g., due to the STA
437	  going outside the range of the AP). Disabled by default, enable by
438	  config option disassoc_low_ack.
439	* Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad
440	  config file.
441	* WPS:
442	  - Send AP Settings as a wrapped Credential attribute to ctrl_iface
443	    in WPS-NEW-AP-SETTINGS.
444	  - Dispatch more WPS events through hostapd ctrl_iface.
445	  - Add mechanism for indicating non-standard WPS errors.
446	  - Change concurrent radio AP to use only one WPS UPnP instance.
447	  - Add wps_check_pin command for processing PIN from user input.
448	    UIs can use this command to process a PIN entered by a user and to
449	    validate the checksum digit (if present).
450	  - Add hostap_cli get_config command to display current AP config.
451	  - Add new hostapd_cli command, wps_ap_pin, to manage AP PIN at
452	    runtime and support dynamic AP PIN management.
453	  - Disable AP PIN after 10 consecutive failures. Slow down attacks
454	    on failures up to 10.
455	  - Allow AP to start in Enrollee mode without AP PIN for probing,
456	    to be compatible with Windows 7.
457	  - Add Config Error into WPS-FAIL events to provide more info
458	    to the user on how to resolve the issue.
459	  - When controlling multiple interfaces:
460	     - apply WPS commands to all interfaces configured to use WPS
461	     - apply WPS config changes to all interfaces that use WPS
462	     - when an attack is detected on any interface, disable AP PIN on
463	       all interfaces
464	* WPS ER:
465	  - Show SetSelectedRegistrar events as ctrl_iface events.
466	  - Add special AP Setup Locked mode to allow read only ER.
467	    ap_setup_locked=2 can now be used to enable a special mode where
468	    WPS ER can learn the current AP settings, but cannot change them.
469	* WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2)
470	  - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool
471	    for testing protocol extensibility.
472	  - Add build option CONFIG_WPS_STRICT to allow disabling of WPS
473	    workarounds.
474	  - Add support for AuthorizedMACs attribute.
475	* TDLS:
476	  - Allow TDLS use or TDLS channel switching in the BSS to be
477	    prohibited in the BSS, using config params tdls_prohibit and
478	    tdls_prohibit_chan_switch.
479	* EAP server: Add support for configuring fragment size (see
480	  fragment_size in hostapd.conf).
481	* wlantest: Add a tool wlantest for IEEE802.11 protocol testing.
482	  wlantest can be used to capture frames from a monitor interface
483	  for realtime capturing or from pcap files for offline analysis.
484	* Interworking: Support added for 802.11u. Enable in .config with
485	  CONFIG_INTERWORKING. See hostapd.conf for config parameters for
486	  interworking.
487	* Android: Add build and runtime support for Android hostapd.
488	* Add a new debug message level for excessive information. Use
489	  -ddd to enable.
490	* TLS: Add support for tls_disable_time_checks=1 in client mode.
491	* Internal TLS:
492	  - Add support for TLS v1.1 (RFC 4346). Enable with build parameter
493	    CONFIG_TLSV11.
494	  - Add domainComponent parser for X.509 names
495	* Reorder some IEs to get closer to IEEE 802.11 standard. Move
496	  WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames.
497	  Move HT IEs to be later in (Re)Assoc Resp.
498	* Many bugfixes.
499

516	* hostapd_notif_Assoc() can now be called with all IEs to simplify
517	  driver wrappers
518	* work around interoperability issue with some WPS External Registrar
519	  implementations
520	* nl80211: fix WPS IE update
521	* hostapd_cli: add support for action script operations (run a script
522	  on hostapd events)
523	* fix DH padding with internal crypto code (mainly, for WPS)
524	* fix WPS association with both WPS IE and WPA/RSN IE present with
525	  driver wrappers that use hostapd MLME (e.g., nl80211)
526
5272010-01-16 - v0.7.1
528	* cleaned up driver wrapper API (struct wpa_driver_ops); the new API
529	  is not fully backwards compatible, so out-of-tree driver wrappers
530	  will need modifications
531	* cleaned up various module interfaces
532	* merge hostapd and wpa_supplicant developers' documentation into a
533	  single document

541	* WPS: add support for dynamically selecting whether to provision the
542	  PSK as an ASCII passphrase or PSK
543	* added support for WDS (4-address frame) mode with per-station virtual
544	  interfaces (wds_sta=1 in config file; only supported with
545	  driver=nl80211 for now)
546	* fixed WPS Probe Request processing to handle missing required
547	  attribute
548	* fixed PKCS#12 use with OpenSSL 1.0.0
549	* detect bridge interface automatically so that bridge parameter in
550	  hostapd.conf becomes optional (though, it may now be used to
551	  automatically add then WLAN interface into a bridge with
552	  driver=nl80211)
553
5542009-11-21 - v0.7.0
555	* increased hostapd_cli ping interval to 5 seconds and made this
556	  configurable with a new command line options (-G<seconds>)
557	* driver_nl80211: use Linux socket filter to improve performance
558	* added support for external Registrars with WPS (UPnP transport)
559	* 802.11n: scan for overlapping BSSes before starting 20/40 MHz channel
560	* driver_nl80211: fixed STA accounting data collection (TX/RX bytes
561	  reported correctly; TX/RX packets not yet available from kernel)
562	* added support for WPS USBA out-of-band mechanism with USB Flash
563	  Drives (UFD) (CONFIG_WPS_UFD=y)
564	* fixed EAPOL/EAP reauthentication when using an external RADIUS
565	  authentication server
566	* fixed TNC with EAP-TTLS
567	* fixed IEEE 802.11r key derivation function to match with the standard
568	  (note: this breaks interoperability with previous version) [Bug 303]
569	* fixed SHA-256 based key derivation function to match with the
570	  standard when using CCMP (for IEEE 802.11r and IEEE 802.11w)
571	  (note: this breaks interoperability with previous version) [Bug 307]
572	* added number of code size optimizations to remove unnecessary
573	  functionality from the program binary based on build configuration
574	  (part of this automatic; part configurable with CONFIG_NO_* build
575	  options)
576	* use shared driver wrapper files with wpa_supplicant
577	* driver_nl80211: multiple updates to provide support for new Linux
578	  nl80211/mac80211 functionality
579	* updated management frame protection to use IEEE Std 802.11w-2009
580	* fixed number of small WPS issues and added workarounds to
581	  interoperate with common deployed broken implementations
582	* added some IEEE 802.11n co-existence rules to disable 40 MHz channels
583	  or modify primary/secondary channels if needed based on neighboring
584	  networks
585	* added support for NFC out-of-band mechanism with WPS
586	* added preliminary support for IEEE 802.11r RIC processing
587
5882009-01-06 - v0.6.7
589	* added support for Wi-Fi Protected Setup (WPS)
590	  (hostapd can now be configured to act as an integrated WPS Registrar
591	  and provision credentials for WPS Enrollees using PIN and PBC
592	  methods; external wireless Registrar can configure the AP, but
593	  external WLAN Manager Registrars are not supported); WPS support can
594	  be enabled by adding CONFIG_WPS=y into .config and setting the
595	  runtime configuration variables in hostapd.conf (see WPS section in
596	  the example configuration file); new hostapd_cli commands wps_pin and
597	  wps_pbc are used to configure WPS negotiation; see README-WPS for
598	  more details
599	* added IEEE 802.11n HT capability configuration (ht_capab)
600	* added support for generating Country IE based on nl80211 regulatory
601	  information (added if ieee80211d=1 in configuration)
602	* fixed WEP authentication (both Open System and Shared Key) with
603	  mac80211
604	* added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
605	* added support for using driver_test over UDP socket
606	* changed EAP-GPSK to use the IANA assigned EAP method type 51
607	* updated management frame protection to use IEEE 802.11w/D7.0
608	* fixed retransmission of EAP requests if no response is received
609
6102008-11-23 - v0.6.6
611	* added a new configuration option, wpa_ptk_rekey, that can be used to
612	  enforce frequent PTK rekeying, e.g., to mitigate some attacks against
613	  TKIP deficiencies
614	* updated OpenSSL code for EAP-FAST to use an updated version of the
615	  session ticket overriding API that was included into the upstream
616	  OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
617	  needed with that version anymore)
618	* changed channel flags configuration to read the information from
619	  the driver (e.g., via driver_nl80211 when using mac80211) instead of
620	  using hostapd as the source of the regulatory information (i.e.,
621	  information from CRDA is now used with mac80211); this allows 5 GHz
622	  channels to be used with hostapd (if allowed in the current
623	  regulatory domain)
624	* fixed EAP-TLS message processing for the last TLS message if it is
625	  large enough to require fragmentation (e.g., if a large Session
626	  Ticket data is included)
627	* fixed listen interval configuration for nl80211 drivers
628
6292008-11-01 - v0.6.5
630	* added support for SHA-256 as X.509 certificate digest when using the
631	  internal X.509/TLSv1 implementation
632	* fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer
633	  identity lengths)
634	* fixed internal TLSv1 implementation for abbreviated handshake (used
635	  by EAP-FAST server)
636	* added support for setting VLAN ID for STAs based on local MAC ACL
637	  (accept_mac_file) as an alternative for RADIUS server-based
638	  configuration
639	* updated management frame protection to use IEEE 802.11w/D6.0
640	  (adds a new association ping to protect against unauthenticated
641	  authenticate or (re)associate request frames dropping association)
642	* added support for using SHA256-based stronger key derivation for WPA2
643	  (IEEE 802.11w)
644	* added new "driver wrapper" for RADIUS-only configuration
645	  (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config)
646	* fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2)
647	  is enabled in configuration
648	* changed EAP-FAST configuration to use separate fields for A-ID and
649	  A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed
650	  16-octet len binary value for better interoperability with some peer
651	  implementations; eap_fast_a_id is now configured as a hex string
652	* driver_nl80211: Updated to match the current Linux mac80211 AP mode
653	  configuration (wireless-testing.git and Linux kernel releases
654	  starting from 2.6.29)
655
6562008-08-10 - v0.6.4
657	* added peer identity into EAP-FAST PAC-Opaque and skip Phase 2
658	  Identity Request if identity is already known
659	* added support for EAP Sequences in EAP-FAST Phase 2
660	* added support for EAP-TNC (Trusted Network Connect)
661	  (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST
662	  changes needed to run two methods in sequence (IF-T) and the IF-IMV
663	  and IF-TNCCS interfaces from TNCS)
664	* added support for optional cryptobinding with PEAPv0
665	* added fragmentation support for EAP-TNC
666	* added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled)
667	  data
668	* added support for opportunistic key caching (OKC)
669
6702008-02-22 - v0.6.3
671	* fixed Reassociation Response callback processing when using internal
672	  MLME (driver_{hostap,nl80211,test}.c)
673	* updated FT support to use the latest draft, IEEE 802.11r/D9.0
674	* copy optional Proxy-State attributes into RADIUS response when acting
675	  as a RADIUS authentication server
676	* fixed EAPOL state machine to handle a case in which no response is
677	  received from the RADIUS authentication server; previous version
678	  could have triggered a crash in some cases after a timeout
679	* fixed EAP-SIM/AKA realm processing to allow decorated usernames to
680	  be used
681	* added a workaround for EAP-SIM/AKA peers that include incorrect null
682	  termination in the username
683	* fixed EAP-SIM/AKA protected result indication to include AT_COUNTER
684	  attribute in notification messages only when using fast
685	  reauthentication
686	* fixed EAP-SIM Start response processing for fast reauthentication
687	  case
688	* added support for pending EAP processing in EAP-{PEAP,TTLS,FAST}
689	  phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method
690
6912008-01-01 - v0.6.2
692	* fixed EAP-SIM and EAP-AKA message parser to validate attribute
693	  lengths properly to avoid potential crash caused by invalid messages
694	* added data structure for storing allocated buffers (struct wpabuf);
695	  this does not affect hostapd usage, but many of the APIs changed
696	  and various interfaces (e.g., EAP) is not compatible with old
697	  versions
698	* added support for protecting EAP-AKA/Identity messages with
699	  AT_CHECKCODE (optional feature in RFC 4187)
700	* added support for protected result indication with AT_RESULT_IND for
701	  EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1)
702	* added support for configuring EAP-TTLS phase 2 non-EAP methods in
703	  EAP server configuration; previously all four were enabled for every
704	  phase 2 user, now all four are disabled by default and need to be
705	  enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP,
706	  TTLS-MSCHAPV2
707	* removed old debug printing mechanism and the related 'debug'
708	  parameter in the configuration file; debug verbosity is now set with
709	  -d (or -dd) command line arguments
710	* added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
711	  only shared key/password authentication is supported in this version
712
7132007-11-24 - v0.6.1
714	* added experimental, integrated TLSv1 server implementation with the
715	  needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
716	  setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
717	  .config); this can be useful, e.g., if the target system does not
718	  have a suitable TLS library and a minimal code size is required
719	* added support for EAP-FAST server method to the integrated EAP
720	  server
721	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
722	  draft (draft-ietf-emu-eap-gpsk-07.txt)
723	* added a new configuration parameter, rsn_pairwise, to allow different
724	  pairwise cipher suites to be enabled for WPA and RSN/WPA2
725	  (note: if wpa_pairwise differs from rsn_pairwise, the driver will
726	  either need to support this or will have to use the WPA/RSN IEs from
727	  hostapd; currently, the included madwifi and bsd driver interfaces do
728	  not have support for this)
729	* updated FT support to use the latest draft, IEEE 802.11r/D8.0
730
7312007-05-28 - v0.6.0
732	* added experimental IEEE 802.11r/D6.0 support
733	* updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
734	* updated EAP-PSK to use the IANA-allocated EAP type 47
735	* fixed EAP-PSK bit ordering of the Flags field
736	* fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
737	  by reading wpa_psk_file [Bug 181]
738	* fixed EAP-TTLS AVP parser processing for too short AVP lengths
739	* fixed IPv6 connection to RADIUS accounting server
740	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
741	  draft (draft-ietf-emu-eap-gpsk-04.txt)
742	* hlr_auc_gw: read GSM triplet file into memory and rotate through the
743	  entries instead of only using the same three triplets every time
744	  (this does not work properly with tests using multiple clients, but
745	  provides bit better triplet data for testing a single client; anyway,
746	  if a better quality triplets are needed, GSM-Milenage should be used
747	  instead of hardcoded triplet file)
748	* fixed EAP-MSCHAPv2 server to use a space between S and M parameters
749	  in Success Request [Bug 203]
750	* added support for sending EAP-AKA Notifications in error cases
751	* updated to use IEEE 802.11w/D2.0 for management frame protection
752	  (still experimental)
753	* RADIUS server: added support for processing duplicate messages
754	  (retransmissions from RADIUS client) by replying with the previous
755	  reply
756
7572006-11-24 - v0.5.6
758	* added support for configuring and controlling multiple BSSes per
759	  radio interface (bss=<ifname> in hostapd.conf); this is only
760	  available with Devicescape and test driver interfaces
761	* fixed PMKSA cache update in the end of successful RSN
762	  pre-authentication
763	* added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
764	  for each STA based on RADIUS Access-Accept attributes); this requires
765	  VLAN support from the kernel driver/802.11 stack and this is
766	  currently only available with Devicescape and test driver interfaces
767	* driver_madwifi: fixed configuration of unencrypted modes (plaintext
768	  and IEEE 802.1X without WEP)
769	* removed STAKey handshake since PeerKey handshake has replaced it in
770	  IEEE 802.11ma and there are no known deployments of STAKey
771	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
772	  draft (draft-ietf-emu-eap-gpsk-01.txt)
773	* added preliminary implementation of IEEE 802.11w/D1.0 (management
774	  frame protection)
775	  (Note: this requires driver support to work properly.)
776	  (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
777	* hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
778	* hlr_auc_gw: added support for reading per-IMSI Milenage keys and
779	  parameters from a text file to make it possible to implement proper
780	  GSM/UMTS authentication server for multiple SIM/USIM cards using
781	  EAP-SIM/EAP-AKA
782	* fixed session timeout processing with drivers that do not use
783	  ieee802_11.c (e.g., madwifi)
784
7852006-08-27 - v0.5.5
786	* added 'hostapd_cli new_sta <addr>' command for adding a new STA into
787	  hostapd (e.g., to initialize wired network authentication based on an
788	  external signal)
789	* fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
790	  using WPA2 even if PMKSA caching is not used
791	* added -P<pid file> argument for hostapd to write the current process
792	  id into a file
793	* added support for RADIUS Authentication Server MIB (RFC 2619)
794
7952006-06-20 - v0.5.4
796	* fixed nt_password_hash build [Bug 144]
797	* added PeerKey handshake implementation for IEEE 802.11e
798	  direct link setup (DLS) to replace STAKey handshake
799	* added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
800	  draft-clancy-emu-eap-shared-secret-00.txt)
801	* fixed a segmentation fault when RSN pre-authentication was completed
802	  successfully [Bug 152]
803
8042006-04-27 - v0.5.3
805	* do not build nt_password_hash and hlr_auc_gw by default to avoid
806	  requiring a TLS library for a successful build; these programs can be
807	  build with 'make nt_password_hash' and 'make hlr_auc_gw'
808	* added a new configuration option, eapol_version, that can be used to
809	  set EAPOL version to 1 (default is 2) to work around broken client
810	  implementations that drop EAPOL frames which use version number 2
811	  [Bug 89]
812	* added support for EAP-SAKE (no EAP method number allocated yet, so
813	  this is using the same experimental type 255 as EAP-PSK)
814	* fixed EAP-MSCHAPv2 message length validation
815
8162006-03-19 - v0.5.2
817	* fixed stdarg use in hostapd_logger(): if both stdout and syslog
818	  logging was enabled, hostapd could trigger a segmentation fault in
819	  vsyslog on some CPU -- C library combinations
820	* moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
821	  program to make it easier to use for implementing real SS7 gateway;
822	  eap_sim_db is not anymore used as a file name for GSM authentication
823	  triplets; instead, it is path to UNIX domain socket that will be used
824	  to communicate with the external gateway program (e.g., hlr_auc_gw)
825	* added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
826	  local information (GSM authentication triplets from a text file and
827	  hardcoded AKA authentication data); this can be used to test EAP-SIM
828	  and EAP-AKA
829	* added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
830	  to make it possible to test EAP-AKA with real USIM cards (this is
831	  disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
832	  to enable this)
833	* driver_madwifi: added support for getting station RSN IE from
834	  madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
835	  broken with earlier change (r1357) in the driver
836	* changed EAP method registration to use a dynamic list of methods
837	  instead of a static list generated at build time
838	* fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
839	  [Bug 125]
840	* added ap_max_inactivity configuration parameter
841
8422006-01-29 - v0.5.1
843	* driver_test: added better support for multiple APs and STAs by using
844	  a directory with sockets that include MAC address for each device in
845	  the name (test_socket=DIR:/tmp/test)
846	* added support for EAP expanded type (vendor specific EAP methods)
847
8482005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
849	* added experimental STAKey handshake implementation for IEEE 802.11e
850	  direct link setup (DLS); note: this is disabled by default in both
851	  build and runtime configuration (can be enabled with CONFIG_STAKEY=y
852	  and stakey=1)
853	* added support for EAP methods to use callbacks to external programs
854	  by buffering a pending request and processing it after the EAP method
855	  is ready to continue
856	* improved EAP-SIM database interface to allow external request to GSM
857	  HLR/AuC without blocking hostapd process
858	* added support for using EAP-SIM pseudonyms and fast re-authentication
859	* added support for EAP-AKA in the integrated EAP authenticator
860	* added support for matching EAP identity prefixes (e.g., "1"*) in EAP
861	  user database to allow EAP-SIM/AKA selection without extra roundtrip
862	  for EAP-Nak negotiation
863	* added support for storing EAP user password as NtPasswordHash instead
864	  of plaintext password when using MSCHAP or MSCHAPv2 for
865	  authentication (hash:<16-octet hex value>); added nt_password_hash
866	  tool for hashing password to generate NtPasswordHash
867
8682005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
869	* driver_wired: fixed EAPOL sending to optionally use PAE group address
870	  as the destination instead of supplicant MAC address; this is
871	  disabled by default, but should be enabled with use_pae_group_addr=1
872	  in configuration file if the wired interface is used by only one
873	  device at the time (common switch configuration)
874	* driver_madwifi: configure driver to use TKIP countermeasures in order
875	  to get correct behavior (IEEE 802.11 association failing; previously,
876	  association succeeded, but hostpad forced disassociation immediately)
877	* driver_madwifi: added support for madwifi-ng
878
8792005-10-27 - v0.4.6
880	* added support for replacing user identity from EAP with RADIUS
881	  User-Name attribute from Access-Accept message, if that is included,
882	  for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
883	  tunneled identity into accounting messages when the RADIUS server
884	  does not support better way of doing this with Class attribute)
885	* driver_madwifi: fixed EAPOL packet receive for configuration where
886	  ath# is part of a bridge interface
887	* added a configuration file and log analyzer script for logwatch
888	* fixed EAPOL state machine step function to process all state
889	  transitions before processing new events; this resolves a race
890	  condition in which EAPOL-Start message could trigger hostapd to send
891	  two EAP-Response/Identity frames to the authentication server
892
8932005-09-25 - v0.4.5
894	* added client CA list to the TLS certificate request in order to make
895	  it easier for the client to select which certificate to use
896	* added experimental support for EAP-PSK
897	* added support for WE-19 (hostap, madwifi)
898
8992005-08-21 - v0.4.4
900	* fixed build without CONFIG_RSN_PREAUTH
901	* fixed FreeBSD build
902
9032005-06-26 - v0.4.3
904	* fixed PMKSA caching to copy User-Name and Class attributes so that
905	  RADIUS accounting gets correct information
906	* start RADIUS accounting only after successful completion of WPA
907	  4-Way Handshake if WPA-PSK is used
908	* fixed PMKSA caching for the case where STA (re)associates without
909	  first disassociating
910
9112005-06-12 - v0.4.2
912	* EAP-PAX is now registered as EAP type 46
913	* fixed EAP-PAX MAC calculation
914	* fixed EAP-PAX CK and ICK key derivation
915	* renamed eap_authenticator configuration variable to eap_server to
916	  better match with RFC 3748 (EAP) terminology
917	* driver_test: added support for testing hostapd with wpa_supplicant
918	  by using test driver interface without any kernel drivers or network
919	  cards
920
9212005-05-22 - v0.4.1
922	* fixed RADIUS server initialization when only auth or acct server
923	  is configured and the other one is left empty
924	* driver_madwifi: added support for RADIUS accounting
925	* driver_madwifi: added preliminary support for compiling against 'BSD'
926	  branch of madwifi CVS tree
927	* driver_madwifi: fixed pairwise key removal to allow WPA reauth
928	  without disassociation
929	* added support for reading additional certificates from PKCS#12 files
930	  and adding them to the certificate chain
931	* fixed RADIUS Class attribute processing to only use Access-Accept
932	  packets to update Class; previously, other RADIUS authentication
933	  packets could have cleared Class attribute
934	* added support for more than one Class attribute in RADIUS packets
935	* added support for verifying certificate revocation list (CRL) when
936	  using integrated EAP authenticator for EAP-TLS; new hostapd.conf
937	  options 'check_crl'; CRL must be included in the ca_cert file for now
938
9392005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
940	* added support for including network information into
941	  EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
942	  (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
943	* fixed a bug which caused some RSN pre-authentication cases to use
944	  freed memory and potentially crash hostapd
945	* fixed private key loading for cases where passphrase is not set
946	* added support for sending TLS alerts and aborting authentication
947	  when receiving a TLS alert
948	* fixed WPA2 to add PMKSA cache entry when using integrated EAP
949	  authenticator
950	* fixed PMKSA caching (EAP authentication was not skipped correctly
951	  with the new state machine changes from IEEE 802.1X draft)
952	* added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
953	  and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
954	  to be added to .config to include IPv6 support); for RADIUS server,
955	  radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
956	  in RADIUS clients file can then use IPv6 format
957	* added experimental support for EAP-PAX
958	* replaced hostapd control interface library (hostapd_ctrl.[ch]) with
959	  the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
960
9612005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
962
9632005-01-23 - v0.3.5
964	* added support for configuring a forced PEAP version based on the
965	  Phase 1 identity
966	* fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
967	  to terminate authentication
968	* fixed EAP identifier duplicate processing with the new IEEE 802.1X
969	  draft
970	* clear accounting data in the driver when starting a new accounting
971	  session
972	* driver_madwifi: filter wireless events based on ifindex to allow more
973	  than one network interface to be used
974	* fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
975	  setting if the packet does not pass MIC verification (e.g., due to
976	  incorrect PSK); previously, message 1/4 was not tried again if an
977	  invalid message 2/4 was received
978	* fixed reconfiguration of RADIUS client retransmission timer when
979	  adding a new message to the pending list; previously, timer was not
980	  updated at this point and if there was a pending message with long
981	  time for the next retry, the new message needed to wait that long for
982	  its first retry, too
983
9842005-01-09 - v0.3.4
985	* added support for configuring multiple allowed EAP types for Phase 2
986	  authentication (EAP-PEAP, EAP-TTLS)
987	* fixed EAPOL-Start processing to trigger WPA reauthentication
988	  (previously, only EAPOL authentication was done)
989
9902005-01-02 - v0.3.3
991	* added support for EAP-PEAP in the integrated EAP authenticator
992	* added support for EAP-GTC in the integrated EAP authenticator
993	* added support for configuring list of EAP methods for Phase 1 so that
994	  the integrated EAP authenticator can, e.g., use the wildcard entry
995	  for EAP-TLS and EAP-PEAP
996	* added support for EAP-TTLS in the integrated EAP authenticator
997	* added support for EAP-SIM in the integrated EAP authenticator
998	* added support for using hostapd as a RADIUS authentication server
999	  with the integrated EAP authenticator taking care of EAP
1000	  authentication (new hostapd.conf options: radius_server_clients and
1001	  radius_server_auth_port); this is not included in default build; use
1002	  CONFIG_RADIUS_SERVER=y in .config to include
1003
10042004-12-19 - v0.3.2
1005	* removed 'daemonize' configuration file option since it has not really
1006	  been used at all for more than year
1007	* driver_madwifi: fixed group key setup and added get_ssid method
1008	* added support for EAP-MSCHAPv2 in the integrated EAP authenticator
1009
10102004-12-12 - v0.3.1
1011	* added support for integrated EAP-TLS authentication (new hostapd.conf
1012	  variables: ca_cert, server_cert, private_key, private_key_passwd);
1013	  this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
1014	  external RADIUS server
1015	* added support for reading PKCS#12 (PFX) files (as a replacement for
1016	  PEM/DER) to get certificate and private key (CONFIG_PKCS12)
1017
10182004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
1019	* added support for Acct-{Input,Output}-Gigawords
1020	* added support for Event-Timestamp (in RADIUS Accounting-Requests)
1021	* added support for RADIUS Authentication Client MIB (RFC2618)
1022	* added support for RADIUS Accounting Client MIB (RFC2620)
1023	* made EAP re-authentication period configurable (eap_reauth_period)
1024	* fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
1025	* fixed EAPOL state machine to stop if STA is removed during
1026	  eapol_sm_step(); this fixes at least one segfault triggering bug with
1027	  IEEE 802.11i pre-authentication
1028	* added support for multiple WPA pre-shared keys (e.g., one for each
1029	  client MAC address or keys shared by a group of clients);
1030	  new hostapd.conf field wpa_psk_file for setting path to a text file
1031	  containing PSKs, see hostapd.wpa_psk for an example
1032	* added support for multiple driver interfaces to allow hostapd to be
1033	  used with other drivers
1034	* added wired authenticator driver interface (driver=wired in
1035	  hostapd.conf, see wired.conf for example configuration)
1036	* added madwifi driver interface (driver=madwifi in hostapd.conf, see
1037	  madwifi.conf for example configuration; Note: include files from
1038	  madwifi project is needed for building and a configuration file,
1039	  .config, needs to be created in hostapd directory with
1040	  CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
1041	  build)
1042	* fixed an alignment issue that could cause SHA-1 to fail on some
1043	  platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
1044	  align variables)
1045	* fixed RADIUS reconnection after an error in sending interim
1046	  accounting packets
1047	* added hostapd control interface for external programs and an example
1048	  CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
1049	* started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
1050	  'hostapd_cli sta <addr>')
1051	* finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
1052	* added support for strict GTK rekeying (wpa_strict_rekey in
1053	  hostapd.conf)
1054	* updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
1055	  (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
1056	  IEEE 802.11F-2003)
1057	* added Prism54 driver interface (driver=prism54 in hostapd.conf;
1058	  note: .config needs to be created in hostapd directory with
1059	  CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
1060	  build)
1061	* dual-licensed hostapd (GPLv2 and BSD licenses)
1062	* fixed RADIUS accounting to generate a new session id for cases where
1063	  a station reassociates without first being complete deauthenticated
1064	* fixed STA disassociation handler to mark next timeout state to
1065	  deauthenticate the station, i.e., skip long wait for inactivity poll
1066	  and extra disassociation, if the STA disassociates without
1067	  deauthenticating
1068	* added integrated EAP authenticator that can be used instead of
1069	  external RADIUS authentication server; currently, only EAP-MD5 is
1070	  supported, so this cannot yet be used for key distribution; the EAP
1071	  method interface is generic, though, so adding new EAP methods should
1072	  be straightforward; new hostapd.conf variables: 'eap_authenticator'
1073	  and 'eap_user_file'; this obsoletes "minimal authentication server"
1074	  ('minimal_eap' in hostapd.conf) which is now removed
1075	* added support for FreeBSD and driver interface for the BSD net80211
1076	  layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
1077	  .config); please note that some of the required kernel mods have not
1078	  yet been committed
1079
10802004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
1081	* fixed some accounting cases where Accounting-Start was sent when
1082	  IEEE 802.1X port was being deauthorized
1083
10842004-06-20 - v0.2.3
1085	* modified RADIUS client to re-connect the socket in case of certain
1086	  error codes that are generated when a network interface state is
1087	  changes (e.g., when IP address changes or the interface is set UP)
1088	* fixed couple of cases where EAPOL state for a station was freed
1089	  twice causing a segfault for hostapd
1090	* fixed couple of bugs in processing WPA deauthentication (freed data
1091	  was used)
1092
10932004-05-31 - v0.2.2
1094	* fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
1095	* fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
1096	  cases where STAs dropped multicast frames as replay attacks
1097	* added support for copying RADIUS Attribute 'Class' from
1098	  authentication messages into accounting messages
1099	* send canned EAP failure if RADIUS server sends Access-Reject without
1100	  EAP message (previously, Supplicant was not notified in this case)
1101	* fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
1102	  not start EAPOL state machines if the STA selected to use WPA-PSK)
1103
11042004-05-06 - v0.2.1
1105	* added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
1106	  - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
1107	    (i.e., IEEE 802.11i/D3.0)
1108	  - supports WPA-only, RSN-only, and mixed WPA/RSN mode
1109	  - both WPA-PSK and WPA-RADIUS/EAP are supported
1110	  - PMKSA caching and pre-authentication
1111	  - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
1112	    wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
1113	    rsn_preauth, rsn_preauth_interfaces
1114	* fixed interim accounting to remove any pending accounting messages
1115	  to the STA before sending a new one
1116
11172004-02-15 - v0.2.0
1118	* added support for Acct-Interim-Interval:
1119	  - draft-ietf-radius-acct-interim-01.txt
1120	  - use Acct-Interim-Interval attribute from Access-Accept if local
1121	    'radius_acct_interim_interval' is not set
1122	  - allow different update intervals for each STA
1123	* fixed event loop to call signal handlers only after returning from
1124	  the real signal handler
1125	* reset sta->timeout_next after successful association to make sure
1126	  that the previously registered inactivity timer will not remove the
1127	  STA immediately (e.g., if STA deauthenticates and re-associates
1128	  before the timer is triggered).
1129	* added new hostapd.conf variable, nas_identifier, that can be used to
1130	  add an optional RADIUS Attribute, NAS-Identifier, into authentication
1131	  and accounting messages
1132	* added support for Accounting-On and Accounting-Off messages
1133	* fixed accounting session handling to send Accounting-Start only once
1134	  per session and not to send Accounting-Stop if the session was not
1135	  initialized properly
1136	* fixed Accounting-Stop statistics in cases where the message was
1137	  previously sent after the kernel entry for the STA (and/or IEEE
1138	  802.1X data) was removed
1139
1140
1141Note:
1142
1143Older changes up to and including v0.1.0 are included in the ChangeLog
1144of the Host AP driver.
