333	* Allow client isolation to be configured with ap_isolate. Client
334	  isolation can be used to prevent low-level bridging of frames
335	  between associated stations in the BSS. By default, this bridging
336	  is allowed.
337	* Allow coexistance of HT BSSes with WEP/TKIP BSSes.

341	* Add support for writing debug log to a file using "-f" option. Also
342	  add relog CLI command to re-open the log file.
343	* Add bridge handling for WDS STA interfaces. By default they are
344	  added to the configured bridge of the AP interface (if present),
345	  but the user can also specify a separate bridge using cli command
346	  wds_bridge.
347	* hostapd_cli:

351	  - Send AP-STA-DISCONNECTED event when an AP disconnects a station
352	    due to inactivity.
353	  - Add wps_config ctrl_interface command for configuring AP. This
354	    command can be used to configure the AP using the internal WPS
355	    registrar. It works in the same way as new AP settings received
356	    from an ER.
357	  - Many WPS/WPS ER commands - see WPS/WPS ER sections for details.
358	  - Add command get version, that returns hostapd version string.
359	* WNM: Add BSS Transition Management Request for ESS Disassoc Imminent.
360	  Use hostapd_cli ess_disassoc (STA addr) (URL) to send the
361	  notification to the STA.
362	* Allow AP mode to disconnect STAs based on low ACK condition (when
363	  the data connection is not working properly, e.g., due to the STA
364	  going outside the range of the AP). Disabled by default, enable by
365	  config option disassoc_low_ack.
366	* Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad
367	  config file.
368	* WPS:
369	  - Send AP Settings as a wrapped Credential attribute to ctrl_iface
370	    in WPS-NEW-AP-SETTINGS.
371	  - Dispatch more WPS events through hostapd ctrl_iface.
372	  - Add mechanism for indicating non-standard WPS errors.
373	  - Change concurrent radio AP to use only one WPS UPnP instance.
374	  - Add wps_check_pin command for processing PIN from user input.
375	    UIs can use this command to process a PIN entered by a user and to
376	    validate the checksum digit (if present).
377	  - Add hostap_cli get_config command to display current AP config.
378	  - Add new hostapd_cli command, wps_ap_pin, to manage AP PIN at
379	    runtime and support dynamic AP PIN management.
380	  - Disable AP PIN after 10 consecutive failures. Slow down attacks
381	    on failures up to 10.
382	  - Allow AP to start in Enrollee mode without AP PIN for probing,
383	    to be compatible with Windows 7.
384	  - Add Config Error into WPS-FAIL events to provide more info
385	    to the user on how to resolve the issue.
386	  - When controlling multiple interfaces:
387	     - apply WPS commands to all interfaces configured to use WPS
388	     - apply WPS config changes to all interfaces that use WPS
389	     - when an attack is detected on any interface, disable AP PIN on
390	       all interfaces
391	* WPS ER:
392	  - Show SetSelectedRegistrar events as ctrl_iface events.
393	  - Add special AP Setup Locked mode to allow read only ER.
394	    ap_setup_locked=2 can now be used to enable a special mode where
395	    WPS ER can learn the current AP settings, but cannot change them.
396	* WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2)
397	  - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool
398	    for testing protocol extensibility.
399	  - Add build option CONFIG_WPS_STRICT to allow disabling of WPS
400	    workarounds.
401	  - Add support for AuthorizedMACs attribute.
402	* TDLS:
403	  - Allow TDLS use or TDLS channel switching in the BSS to be
404	    prohibited in the BSS, using config params tdls_prohibit and
405	    tdls_prohibit_chan_switch.
406	* EAP server: Add support for configuring fragment size (see
407	  fragment_size in hostapd.conf).
408	* wlantest: Add a tool wlantest for IEEE802.11 protocol testing.
409	  wlantest can be used to capture frames from a monitor interface
410	  for realtime capturing or from pcap files for offline analysis.
411	* Interworking: Support added for 802.11u. Enable in .config with
412	  CONFIG_INTERWORKING. See hostapd.conf for config parameters for
413	  interworking.

423	  WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames.
424	  Move HT IEs to be later in (Re)Assoc Resp.
425	* Many bugfixes.
426

431	  configuration options
432	* TNC: fixed issues with fragmentation
433	* EAP-TNC: add Flags field into fragment acknowledgement (needed to
434	  interoperate with other implementations; may potentially breaks
435	  compatibility with older wpa_supplicant/hostapd versions)
436	* cleaned up driver wrapper API for multi-BSS operations
437	* nl80211: fix multi-BSS and VLAN operations
438	* fix number of issues with IEEE 802.11r/FT; this version is not

443	* hostapd_notif_Assoc() can now be called with all IEs to simplify
444	  driver wrappers
445	* work around interoperability issue with some WPS External Registrar
446	  implementations
447	* nl80211: fix WPS IE update
448	* hostapd_cli: add support for action script operations (run a script
449	  on hostapd events)
450	* fix DH padding with internal crypto code (mainly, for WPS)
451	* fix WPS association with both WPS IE and WPA/RSN IE present with
452	  driver wrappers that use hostapd MLME (e.g., nl80211)
453
4542010-01-16 - v0.7.1
455	* cleaned up driver wrapper API (struct wpa_driver_ops); the new API
456	  is not fully backwards compatible, so out-of-tree driver wrappers
457	  will need modifications
458	* cleaned up various module interfaces
459	* merge hostapd and wpa_supplicant developers' documentation into a
460	  single document

468	* WPS: add support for dynamically selecting whether to provision the
469	  PSK as an ASCII passphrase or PSK
470	* added support for WDS (4-address frame) mode with per-station virtual
471	  interfaces (wds_sta=1 in config file; only supported with
472	  driver=nl80211 for now)
473	* fixed WPS Probe Request processing to handle missing required
474	  attribute
475	* fixed PKCS#12 use with OpenSSL 1.0.0
476	* detect bridge interface automatically so that bridge parameter in
477	  hostapd.conf becomes optional (though, it may now be used to
478	  automatically add then WLAN interface into a bridge with
479	  driver=nl80211)
480
4812009-11-21 - v0.7.0
482	* increased hostapd_cli ping interval to 5 seconds and made this
483	  configurable with a new command line options (-G<seconds>)
484	* driver_nl80211: use Linux socket filter to improve performance
485	* added support for external Registrars with WPS (UPnP transport)
486	* 802.11n: scan for overlapping BSSes before starting 20/40 MHz channel
487	* driver_nl80211: fixed STA accounting data collection (TX/RX bytes
488	  reported correctly; TX/RX packets not yet available from kernel)
489	* added support for WPS USBA out-of-band mechanism with USB Flash
490	  Drives (UFD) (CONFIG_WPS_UFD=y)
491	* fixed EAPOL/EAP reauthentication when using an external RADIUS
492	  authentication server
493	* fixed TNC with EAP-TTLS
494	* fixed IEEE 802.11r key derivation function to match with the standard
495	  (note: this breaks interoperability with previous version) [Bug 303]
496	* fixed SHA-256 based key derivation function to match with the
497	  standard when using CCMP (for IEEE 802.11r and IEEE 802.11w)
498	  (note: this breaks interoperability with previous version) [Bug 307]
499	* added number of code size optimizations to remove unnecessary
500	  functionality from the program binary based on build configuration
501	  (part of this automatic; part configurable with CONFIG_NO_* build
502	  options)
503	* use shared driver wrapper files with wpa_supplicant
504	* driver_nl80211: multiple updates to provide support for new Linux
505	  nl80211/mac80211 functionality
506	* updated management frame protection to use IEEE Std 802.11w-2009
507	* fixed number of small WPS issues and added workarounds to
508	  interoperate with common deployed broken implementations
509	* added some IEEE 802.11n co-existence rules to disable 40 MHz channels
510	  or modify primary/secondary channels if needed based on neighboring
511	  networks
512	* added support for NFC out-of-band mechanism with WPS
513	* added preliminary support for IEEE 802.11r RIC processing
514
5152009-01-06 - v0.6.7
516	* added support for Wi-Fi Protected Setup (WPS)
517	  (hostapd can now be configured to act as an integrated WPS Registrar
518	  and provision credentials for WPS Enrollees using PIN and PBC
519	  methods; external wireless Registrar can configure the AP, but
520	  external WLAN Manager Registrars are not supported); WPS support can
521	  be enabled by adding CONFIG_WPS=y into .config and setting the
522	  runtime configuration variables in hostapd.conf (see WPS section in
523	  the example configuration file); new hostapd_cli commands wps_pin and
524	  wps_pbc are used to configure WPS negotiation; see README-WPS for
525	  more details
526	* added IEEE 802.11n HT capability configuration (ht_capab)
527	* added support for generating Country IE based on nl80211 regulatory
528	  information (added if ieee80211d=1 in configuration)
529	* fixed WEP authentication (both Open System and Shared Key) with
530	  mac80211
531	* added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
532	* added support for using driver_test over UDP socket
533	* changed EAP-GPSK to use the IANA assigned EAP method type 51
534	* updated management frame protection to use IEEE 802.11w/D7.0
535	* fixed retransmission of EAP requests if no response is received
536
5372008-11-23 - v0.6.6
538	* added a new configuration option, wpa_ptk_rekey, that can be used to
539	  enforce frequent PTK rekeying, e.g., to mitigate some attacks against
540	  TKIP deficiencies
541	* updated OpenSSL code for EAP-FAST to use an updated version of the
542	  session ticket overriding API that was included into the upstream
543	  OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
544	  needed with that version anymore)
545	* changed channel flags configuration to read the information from
546	  the driver (e.g., via driver_nl80211 when using mac80211) instead of
547	  using hostapd as the source of the regulatory information (i.e.,
548	  information from CRDA is now used with mac80211); this allows 5 GHz
549	  channels to be used with hostapd (if allowed in the current
550	  regulatory domain)
551	* fixed EAP-TLS message processing for the last TLS message if it is
552	  large enough to require fragmentation (e.g., if a large Session
553	  Ticket data is included)
554	* fixed listen interval configuration for nl80211 drivers
555
5562008-11-01 - v0.6.5
557	* added support for SHA-256 as X.509 certificate digest when using the
558	  internal X.509/TLSv1 implementation
559	* fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer
560	  identity lengths)
561	* fixed internal TLSv1 implementation for abbreviated handshake (used
562	  by EAP-FAST server)
563	* added support for setting VLAN ID for STAs based on local MAC ACL
564	  (accept_mac_file) as an alternative for RADIUS server-based
565	  configuration
566	* updated management frame protection to use IEEE 802.11w/D6.0
567	  (adds a new association ping to protect against unauthenticated
568	  authenticate or (re)associate request frames dropping association)
569	* added support for using SHA256-based stronger key derivation for WPA2
570	  (IEEE 802.11w)
571	* added new "driver wrapper" for RADIUS-only configuration
572	  (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config)
573	* fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2)
574	  is enabled in configuration
575	* changed EAP-FAST configuration to use separate fields for A-ID and
576	  A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed
577	  16-octet len binary value for better interoperability with some peer
578	  implementations; eap_fast_a_id is now configured as a hex string
579	* driver_nl80211: Updated to match the current Linux mac80211 AP mode
580	  configuration (wireless-testing.git and Linux kernel releases
581	  starting from 2.6.29)
582
5832008-08-10 - v0.6.4
584	* added peer identity into EAP-FAST PAC-Opaque and skip Phase 2
585	  Identity Request if identity is already known
586	* added support for EAP Sequences in EAP-FAST Phase 2
587	* added support for EAP-TNC (Trusted Network Connect)
588	  (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST
589	  changes needed to run two methods in sequence (IF-T) and the IF-IMV
590	  and IF-TNCCS interfaces from TNCS)
591	* added support for optional cryptobinding with PEAPv0
592	* added fragmentation support for EAP-TNC
593	* added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled)
594	  data
595	* added support for opportunistic key caching (OKC)
596
5972008-02-22 - v0.6.3
598	* fixed Reassociation Response callback processing when using internal
599	  MLME (driver_{hostap,nl80211,test}.c)
600	* updated FT support to use the latest draft, IEEE 802.11r/D9.0
601	* copy optional Proxy-State attributes into RADIUS response when acting
602	  as a RADIUS authentication server
603	* fixed EAPOL state machine to handle a case in which no response is
604	  received from the RADIUS authentication server; previous version
605	  could have triggered a crash in some cases after a timeout
606	* fixed EAP-SIM/AKA realm processing to allow decorated usernames to
607	  be used
608	* added a workaround for EAP-SIM/AKA peers that include incorrect null
609	  termination in the username
610	* fixed EAP-SIM/AKA protected result indication to include AT_COUNTER
611	  attribute in notification messages only when using fast
612	  reauthentication
613	* fixed EAP-SIM Start response processing for fast reauthentication
614	  case
615	* added support for pending EAP processing in EAP-{PEAP,TTLS,FAST}
616	  phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method
617
6182008-01-01 - v0.6.2
619	* fixed EAP-SIM and EAP-AKA message parser to validate attribute
620	  lengths properly to avoid potential crash caused by invalid messages
621	* added data structure for storing allocated buffers (struct wpabuf);
622	  this does not affect hostapd usage, but many of the APIs changed
623	  and various interfaces (e.g., EAP) is not compatible with old
624	  versions
625	* added support for protecting EAP-AKA/Identity messages with
626	  AT_CHECKCODE (optional feature in RFC 4187)
627	* added support for protected result indication with AT_RESULT_IND for
628	  EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1)
629	* added support for configuring EAP-TTLS phase 2 non-EAP methods in
630	  EAP server configuration; previously all four were enabled for every
631	  phase 2 user, now all four are disabled by default and need to be
632	  enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP,
633	  TTLS-MSCHAPV2
634	* removed old debug printing mechanism and the related 'debug'
635	  parameter in the configuration file; debug verbosity is now set with
636	  -d (or -dd) command line arguments
637	* added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
638	  only shared key/password authentication is supported in this version
639
6402007-11-24 - v0.6.1
641	* added experimental, integrated TLSv1 server implementation with the
642	  needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
643	  setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
644	  .config); this can be useful, e.g., if the target system does not
645	  have a suitable TLS library and a minimal code size is required
646	* added support for EAP-FAST server method to the integrated EAP
647	  server
648	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
649	  draft (draft-ietf-emu-eap-gpsk-07.txt)
650	* added a new configuration parameter, rsn_pairwise, to allow different
651	  pairwise cipher suites to be enabled for WPA and RSN/WPA2
652	  (note: if wpa_pairwise differs from rsn_pairwise, the driver will
653	  either need to support this or will have to use the WPA/RSN IEs from
654	  hostapd; currently, the included madwifi and bsd driver interfaces do
655	  not have support for this)
656	* updated FT support to use the latest draft, IEEE 802.11r/D8.0
657
6582007-05-28 - v0.6.0
659	* added experimental IEEE 802.11r/D6.0 support
660	* updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
661	* updated EAP-PSK to use the IANA-allocated EAP type 47
662	* fixed EAP-PSK bit ordering of the Flags field
663	* fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
664	  by reading wpa_psk_file [Bug 181]
665	* fixed EAP-TTLS AVP parser processing for too short AVP lengths
666	* fixed IPv6 connection to RADIUS accounting server
667	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
668	  draft (draft-ietf-emu-eap-gpsk-04.txt)
669	* hlr_auc_gw: read GSM triplet file into memory and rotate through the
670	  entries instead of only using the same three triplets every time
671	  (this does not work properly with tests using multiple clients, but
672	  provides bit better triplet data for testing a single client; anyway,
673	  if a better quality triplets are needed, GSM-Milenage should be used
674	  instead of hardcoded triplet file)
675	* fixed EAP-MSCHAPv2 server to use a space between S and M parameters
676	  in Success Request [Bug 203]
677	* added support for sending EAP-AKA Notifications in error cases
678	* updated to use IEEE 802.11w/D2.0 for management frame protection
679	  (still experimental)
680	* RADIUS server: added support for processing duplicate messages
681	  (retransmissions from RADIUS client) by replying with the previous
682	  reply
683
6842006-11-24 - v0.5.6
685	* added support for configuring and controlling multiple BSSes per
686	  radio interface (bss=<ifname> in hostapd.conf); this is only
687	  available with Devicescape and test driver interfaces
688	* fixed PMKSA cache update in the end of successful RSN
689	  pre-authentication
690	* added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
691	  for each STA based on RADIUS Access-Accept attributes); this requires
692	  VLAN support from the kernel driver/802.11 stack and this is
693	  currently only available with Devicescape and test driver interfaces
694	* driver_madwifi: fixed configuration of unencrypted modes (plaintext
695	  and IEEE 802.1X without WEP)
696	* removed STAKey handshake since PeerKey handshake has replaced it in
697	  IEEE 802.11ma and there are no known deployments of STAKey
698	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
699	  draft (draft-ietf-emu-eap-gpsk-01.txt)
700	* added preliminary implementation of IEEE 802.11w/D1.0 (management
701	  frame protection)
702	  (Note: this requires driver support to work properly.)
703	  (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
704	* hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
705	* hlr_auc_gw: added support for reading per-IMSI Milenage keys and
706	  parameters from a text file to make it possible to implement proper
707	  GSM/UMTS authentication server for multiple SIM/USIM cards using
708	  EAP-SIM/EAP-AKA
709	* fixed session timeout processing with drivers that do not use
710	  ieee802_11.c (e.g., madwifi)
711
7122006-08-27 - v0.5.5
713	* added 'hostapd_cli new_sta <addr>' command for adding a new STA into
714	  hostapd (e.g., to initialize wired network authentication based on an
715	  external signal)
716	* fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
717	  using WPA2 even if PMKSA caching is not used
718	* added -P<pid file> argument for hostapd to write the current process
719	  id into a file
720	* added support for RADIUS Authentication Server MIB (RFC 2619)
721
7222006-06-20 - v0.5.4
723	* fixed nt_password_hash build [Bug 144]
724	* added PeerKey handshake implementation for IEEE 802.11e
725	  direct link setup (DLS) to replace STAKey handshake
726	* added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
727	  draft-clancy-emu-eap-shared-secret-00.txt)
728	* fixed a segmentation fault when RSN pre-authentication was completed
729	  successfully [Bug 152]
730
7312006-04-27 - v0.5.3
732	* do not build nt_password_hash and hlr_auc_gw by default to avoid
733	  requiring a TLS library for a successful build; these programs can be
734	  build with 'make nt_password_hash' and 'make hlr_auc_gw'
735	* added a new configuration option, eapol_version, that can be used to
736	  set EAPOL version to 1 (default is 2) to work around broken client
737	  implementations that drop EAPOL frames which use version number 2
738	  [Bug 89]
739	* added support for EAP-SAKE (no EAP method number allocated yet, so
740	  this is using the same experimental type 255 as EAP-PSK)
741	* fixed EAP-MSCHAPv2 message length validation
742
7432006-03-19 - v0.5.2
744	* fixed stdarg use in hostapd_logger(): if both stdout and syslog
745	  logging was enabled, hostapd could trigger a segmentation fault in
746	  vsyslog on some CPU -- C library combinations
747	* moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
748	  program to make it easier to use for implementing real SS7 gateway;
749	  eap_sim_db is not anymore used as a file name for GSM authentication
750	  triplets; instead, it is path to UNIX domain socket that will be used
751	  to communicate with the external gateway program (e.g., hlr_auc_gw)
752	* added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
753	  local information (GSM authentication triplets from a text file and
754	  hardcoded AKA authentication data); this can be used to test EAP-SIM
755	  and EAP-AKA
756	* added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
757	  to make it possible to test EAP-AKA with real USIM cards (this is
758	  disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
759	  to enable this)
760	* driver_madwifi: added support for getting station RSN IE from
761	  madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
762	  broken with earlier change (r1357) in the driver
763	* changed EAP method registration to use a dynamic list of methods
764	  instead of a static list generated at build time
765	* fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
766	  [Bug 125]
767	* added ap_max_inactivity configuration parameter
768
7692006-01-29 - v0.5.1
770	* driver_test: added better support for multiple APs and STAs by using
771	  a directory with sockets that include MAC address for each device in
772	  the name (test_socket=DIR:/tmp/test)
773	* added support for EAP expanded type (vendor specific EAP methods)
774
7752005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
776	* added experimental STAKey handshake implementation for IEEE 802.11e
777	  direct link setup (DLS); note: this is disabled by default in both
778	  build and runtime configuration (can be enabled with CONFIG_STAKEY=y
779	  and stakey=1)
780	* added support for EAP methods to use callbacks to external programs
781	  by buffering a pending request and processing it after the EAP method
782	  is ready to continue
783	* improved EAP-SIM database interface to allow external request to GSM
784	  HLR/AuC without blocking hostapd process
785	* added support for using EAP-SIM pseudonyms and fast re-authentication
786	* added support for EAP-AKA in the integrated EAP authenticator
787	* added support for matching EAP identity prefixes (e.g., "1"*) in EAP
788	  user database to allow EAP-SIM/AKA selection without extra roundtrip
789	  for EAP-Nak negotiation
790	* added support for storing EAP user password as NtPasswordHash instead
791	  of plaintext password when using MSCHAP or MSCHAPv2 for
792	  authentication (hash:<16-octet hex value>); added nt_password_hash
793	  tool for hashing password to generate NtPasswordHash
794
7952005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
796	* driver_wired: fixed EAPOL sending to optionally use PAE group address
797	  as the destination instead of supplicant MAC address; this is
798	  disabled by default, but should be enabled with use_pae_group_addr=1
799	  in configuration file if the wired interface is used by only one
800	  device at the time (common switch configuration)
801	* driver_madwifi: configure driver to use TKIP countermeasures in order
802	  to get correct behavior (IEEE 802.11 association failing; previously,
803	  association succeeded, but hostpad forced disassociation immediately)
804	* driver_madwifi: added support for madwifi-ng
805
8062005-10-27 - v0.4.6
807	* added support for replacing user identity from EAP with RADIUS
808	  User-Name attribute from Access-Accept message, if that is included,
809	  for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
810	  tunneled identity into accounting messages when the RADIUS server
811	  does not support better way of doing this with Class attribute)
812	* driver_madwifi: fixed EAPOL packet receive for configuration where
813	  ath# is part of a bridge interface
814	* added a configuration file and log analyzer script for logwatch
815	* fixed EAPOL state machine step function to process all state
816	  transitions before processing new events; this resolves a race
817	  condition in which EAPOL-Start message could trigger hostapd to send
818	  two EAP-Response/Identity frames to the authentication server
819
8202005-09-25 - v0.4.5
821	* added client CA list to the TLS certificate request in order to make
822	  it easier for the client to select which certificate to use
823	* added experimental support for EAP-PSK
824	* added support for WE-19 (hostap, madwifi)
825
8262005-08-21 - v0.4.4
827	* fixed build without CONFIG_RSN_PREAUTH
828	* fixed FreeBSD build
829
8302005-06-26 - v0.4.3
831	* fixed PMKSA caching to copy User-Name and Class attributes so that
832	  RADIUS accounting gets correct information
833	* start RADIUS accounting only after successful completion of WPA
834	  4-Way Handshake if WPA-PSK is used
835	* fixed PMKSA caching for the case where STA (re)associates without
836	  first disassociating
837
8382005-06-12 - v0.4.2
839	* EAP-PAX is now registered as EAP type 46
840	* fixed EAP-PAX MAC calculation
841	* fixed EAP-PAX CK and ICK key derivation
842	* renamed eap_authenticator configuration variable to eap_server to
843	  better match with RFC 3748 (EAP) terminology
844	* driver_test: added support for testing hostapd with wpa_supplicant
845	  by using test driver interface without any kernel drivers or network
846	  cards
847
8482005-05-22 - v0.4.1
849	* fixed RADIUS server initialization when only auth or acct server
850	  is configured and the other one is left empty
851	* driver_madwifi: added support for RADIUS accounting
852	* driver_madwifi: added preliminary support for compiling against 'BSD'
853	  branch of madwifi CVS tree
854	* driver_madwifi: fixed pairwise key removal to allow WPA reauth
855	  without disassociation
856	* added support for reading additional certificates from PKCS#12 files
857	  and adding them to the certificate chain
858	* fixed RADIUS Class attribute processing to only use Access-Accept
859	  packets to update Class; previously, other RADIUS authentication
860	  packets could have cleared Class attribute
861	* added support for more than one Class attribute in RADIUS packets
862	* added support for verifying certificate revocation list (CRL) when
863	  using integrated EAP authenticator for EAP-TLS; new hostapd.conf
864	  options 'check_crl'; CRL must be included in the ca_cert file for now
865
8662005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
867	* added support for including network information into
868	  EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
869	  (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
870	* fixed a bug which caused some RSN pre-authentication cases to use
871	  freed memory and potentially crash hostapd
872	* fixed private key loading for cases where passphrase is not set
873	* added support for sending TLS alerts and aborting authentication
874	  when receiving a TLS alert
875	* fixed WPA2 to add PMKSA cache entry when using integrated EAP
876	  authenticator
877	* fixed PMKSA caching (EAP authentication was not skipped correctly
878	  with the new state machine changes from IEEE 802.1X draft)
879	* added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
880	  and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
881	  to be added to .config to include IPv6 support); for RADIUS server,
882	  radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
883	  in RADIUS clients file can then use IPv6 format
884	* added experimental support for EAP-PAX
885	* replaced hostapd control interface library (hostapd_ctrl.[ch]) with
886	  the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
887
8882005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
889
8902005-01-23 - v0.3.5
891	* added support for configuring a forced PEAP version based on the
892	  Phase 1 identity
893	* fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
894	  to terminate authentication
895	* fixed EAP identifier duplicate processing with the new IEEE 802.1X
896	  draft
897	* clear accounting data in the driver when starting a new accounting
898	  session
899	* driver_madwifi: filter wireless events based on ifindex to allow more
900	  than one network interface to be used
901	* fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
902	  setting if the packet does not pass MIC verification (e.g., due to
903	  incorrect PSK); previously, message 1/4 was not tried again if an
904	  invalid message 2/4 was received
905	* fixed reconfiguration of RADIUS client retransmission timer when
906	  adding a new message to the pending list; previously, timer was not
907	  updated at this point and if there was a pending message with long
908	  time for the next retry, the new message needed to wait that long for
909	  its first retry, too
910
9112005-01-09 - v0.3.4
912	* added support for configuring multiple allowed EAP types for Phase 2
913	  authentication (EAP-PEAP, EAP-TTLS)
914	* fixed EAPOL-Start processing to trigger WPA reauthentication
915	  (previously, only EAPOL authentication was done)
916
9172005-01-02 - v0.3.3
918	* added support for EAP-PEAP in the integrated EAP authenticator
919	* added support for EAP-GTC in the integrated EAP authenticator
920	* added support for configuring list of EAP methods for Phase 1 so that
921	  the integrated EAP authenticator can, e.g., use the wildcard entry
922	  for EAP-TLS and EAP-PEAP
923	* added support for EAP-TTLS in the integrated EAP authenticator
924	* added support for EAP-SIM in the integrated EAP authenticator
925	* added support for using hostapd as a RADIUS authentication server
926	  with the integrated EAP authenticator taking care of EAP
927	  authentication (new hostapd.conf options: radius_server_clients and
928	  radius_server_auth_port); this is not included in default build; use
929	  CONFIG_RADIUS_SERVER=y in .config to include
930
9312004-12-19 - v0.3.2
932	* removed 'daemonize' configuration file option since it has not really
933	  been used at all for more than year
934	* driver_madwifi: fixed group key setup and added get_ssid method
935	* added support for EAP-MSCHAPv2 in the integrated EAP authenticator
936
9372004-12-12 - v0.3.1
938	* added support for integrated EAP-TLS authentication (new hostapd.conf
939	  variables: ca_cert, server_cert, private_key, private_key_passwd);
940	  this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
941	  external RADIUS server
942	* added support for reading PKCS#12 (PFX) files (as a replacement for
943	  PEM/DER) to get certificate and private key (CONFIG_PKCS12)
944
9452004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
946	* added support for Acct-{Input,Output}-Gigawords
947	* added support for Event-Timestamp (in RADIUS Accounting-Requests)
948	* added support for RADIUS Authentication Client MIB (RFC2618)
949	* added support for RADIUS Accounting Client MIB (RFC2620)
950	* made EAP re-authentication period configurable (eap_reauth_period)
951	* fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
952	* fixed EAPOL state machine to stop if STA is removed during
953	  eapol_sm_step(); this fixes at least one segfault triggering bug with
954	  IEEE 802.11i pre-authentication
955	* added support for multiple WPA pre-shared keys (e.g., one for each
956	  client MAC address or keys shared by a group of clients);
957	  new hostapd.conf field wpa_psk_file for setting path to a text file
958	  containing PSKs, see hostapd.wpa_psk for an example
959	* added support for multiple driver interfaces to allow hostapd to be
960	  used with other drivers
961	* added wired authenticator driver interface (driver=wired in
962	  hostapd.conf, see wired.conf for example configuration)
963	* added madwifi driver interface (driver=madwifi in hostapd.conf, see
964	  madwifi.conf for example configuration; Note: include files from
965	  madwifi project is needed for building and a configuration file,
966	  .config, needs to be created in hostapd directory with
967	  CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
968	  build)
969	* fixed an alignment issue that could cause SHA-1 to fail on some
970	  platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
971	  align variables)
972	* fixed RADIUS reconnection after an error in sending interim
973	  accounting packets
974	* added hostapd control interface for external programs and an example
975	  CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
976	* started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
977	  'hostapd_cli sta <addr>')
978	* finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
979	* added support for strict GTK rekeying (wpa_strict_rekey in
980	  hostapd.conf)
981	* updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
982	  (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
983	  IEEE 802.11F-2003)
984	* added Prism54 driver interface (driver=prism54 in hostapd.conf;
985	  note: .config needs to be created in hostapd directory with
986	  CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
987	  build)
988	* dual-licensed hostapd (GPLv2 and BSD licenses)
989	* fixed RADIUS accounting to generate a new session id for cases where
990	  a station reassociates without first being complete deauthenticated
991	* fixed STA disassociation handler to mark next timeout state to
992	  deauthenticate the station, i.e., skip long wait for inactivity poll
993	  and extra disassociation, if the STA disassociates without
994	  deauthenticating
995	* added integrated EAP authenticator that can be used instead of
996	  external RADIUS authentication server; currently, only EAP-MD5 is
997	  supported, so this cannot yet be used for key distribution; the EAP
998	  method interface is generic, though, so adding new EAP methods should
999	  be straightforward; new hostapd.conf variables: 'eap_authenticator'
1000	  and 'eap_user_file'; this obsoletes "minimal authentication server"
1001	  ('minimal_eap' in hostapd.conf) which is now removed
1002	* added support for FreeBSD and driver interface for the BSD net80211
1003	  layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
1004	  .config); please note that some of the required kernel mods have not
1005	  yet been committed
1006
10072004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
1008	* fixed some accounting cases where Accounting-Start was sent when
1009	  IEEE 802.1X port was being deauthorized
1010
10112004-06-20 - v0.2.3
1012	* modified RADIUS client to re-connect the socket in case of certain
1013	  error codes that are generated when a network interface state is
1014	  changes (e.g., when IP address changes or the interface is set UP)
1015	* fixed couple of cases where EAPOL state for a station was freed
1016	  twice causing a segfault for hostapd
1017	* fixed couple of bugs in processing WPA deauthentication (freed data
1018	  was used)
1019
10202004-05-31 - v0.2.2
1021	* fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
1022	* fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
1023	  cases where STAs dropped multicast frames as replay attacks
1024	* added support for copying RADIUS Attribute 'Class' from
1025	  authentication messages into accounting messages
1026	* send canned EAP failure if RADIUS server sends Access-Reject without
1027	  EAP message (previously, Supplicant was not notified in this case)
1028	* fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
1029	  not start EAPOL state machines if the STA selected to use WPA-PSK)
1030
10312004-05-06 - v0.2.1
1032	* added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
1033	  - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
1034	    (i.e., IEEE 802.11i/D3.0)
1035	  - supports WPA-only, RSN-only, and mixed WPA/RSN mode
1036	  - both WPA-PSK and WPA-RADIUS/EAP are supported
1037	  - PMKSA caching and pre-authentication
1038	  - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
1039	    wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
1040	    rsn_preauth, rsn_preauth_interfaces
1041	* fixed interim accounting to remove any pending accounting messages
1042	  to the STA before sending a new one
1043
10442004-02-15 - v0.2.0
1045	* added support for Acct-Interim-Interval:
1046	  - draft-ietf-radius-acct-interim-01.txt
1047	  - use Acct-Interim-Interval attribute from Access-Accept if local
1048	    'radius_acct_interim_interval' is not set
1049	  - allow different update intervals for each STA
1050	* fixed event loop to call signal handlers only after returning from
1051	  the real signal handler
1052	* reset sta->timeout_next after successful association to make sure
1053	  that the previously registered inactivity timer will not remove the
1054	  STA immediately (e.g., if STA deauthenticates and re-associates
1055	  before the timer is triggered).
1056	* added new hostapd.conf variable, nas_identifier, that can be used to
1057	  add an optional RADIUS Attribute, NAS-Identifier, into authentication
1058	  and accounting messages
1059	* added support for Accounting-On and Accounting-Off messages
1060	* fixed accounting session handling to send Accounting-Start only once
1061	  per session and not to send Accounting-Stop if the session was not
1062	  initialized properly
1063	* fixed Accounting-Stop statistics in cases where the message was
1064	  previously sent after the kernel entry for the STA (and/or IEEE
1065	  802.1X data) was removed
1066
1067
