285	* Add channel selection support in hostapd. See hostapd.conf.
286	* Add support for IEEE 802.11v Time Advertisement mechanism with UTC
287	  TSF offset. See hostapd.conf for config info.
288	* Delay STA entry removal until Deauth/Disassoc TX status in AP mode.
289	  This allows the driver to use PS buffering of Deauthentication and
290	  Disassociation frames when the STA is in power save sleep. Only
291	  available with drivers that provide TX status events for Deauth/
292	  Disassoc frames (nl80211).

296	* bsd: Add support for setting HT values in IFM_MMASK.
297	* Allow client isolation to be configured with ap_isolate. Client
298	  isolation can be used to prevent low-level bridging of frames
299	  between associated stations in the BSS. By default, this bridging
300	  is allowed.
301	* Allow coexistance of HT BSSes with WEP/TKIP BSSes.
302	* Add require_ht config parameter, which can be used to configure
303	  hostapd to reject association with any station that does not support
304	  HT PHY.
305	* Add support for writing debug log to a file using "-f" option. Also
306	  add relog CLI command to re-open the log file.
307	* Add bridge handling for WDS STA interfaces. By default they are
308	  added to the configured bridge of the AP interface (if present),
309	  but the user can also specify a separate bridge using cli command
310	  wds_bridge.
311	* hostapd_cli:
312	  - Add wds_bridge command for specifying bridge for WDS STA
313	    interfaces.
314	  - Add relog command for reopening log file.
315	  - Send AP-STA-DISCONNECTED event when an AP disconnects a station
316	    due to inactivity.
317	  - Add wps_config ctrl_interface command for configuring AP. This
318	    command can be used to configure the AP using the internal WPS
319	    registrar. It works in the same way as new AP settings received
320	    from an ER.
321	  - Many WPS/WPS ER commands - see WPS/WPS ER sections for details.
322	  - Add command get version, that returns hostapd version string.
323	* WNM: Add BSS Transition Management Request for ESS Disassoc Imminent.
324	  Use hostapd_cli ess_disassoc (STA addr) (URL) to send the
325	  notification to the STA.
326	* Allow AP mode to disconnect STAs based on low ACK condition (when
327	  the data connection is not working properly, e.g., due to the STA
328	  going outside the range of the AP). Disabled by default, enable by
329	  config option disassoc_low_ack.
330	* Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad
331	  config file.
332	* WPS:
333	  - Send AP Settings as a wrapped Credential attribute to ctrl_iface
334	    in WPS-NEW-AP-SETTINGS.
335	  - Dispatch more WPS events through hostapd ctrl_iface.
336	  - Add mechanism for indicating non-standard WPS errors.
337	  - Change concurrent radio AP to use only one WPS UPnP instance.
338	  - Add wps_check_pin command for processing PIN from user input.
339	    UIs can use this command to process a PIN entered by a user and to
340	    validate the checksum digit (if present).
341	  - Add hostap_cli get_config command to display current AP config.
342	  - Add new hostapd_cli command, wps_ap_pin, to manage AP PIN at
343	    runtime and support dynamic AP PIN management.
344	  - Disable AP PIN after 10 consecutive failures. Slow down attacks
345	    on failures up to 10.
346	  - Allow AP to start in Enrollee mode without AP PIN for probing,
347	    to be compatible with Windows 7.
348	  - Add Config Error into WPS-FAIL events to provide more info
349	    to the user on how to resolve the issue.
350	  - When controlling multiple interfaces:
351	     - apply WPS commands to all interfaces configured to use WPS
352	     - apply WPS config changes to all interfaces that use WPS
353	     - when an attack is detected on any interface, disable AP PIN on
354	       all interfaces
355	* WPS ER:
356	  - Show SetSelectedRegistrar events as ctrl_iface events.
357	  - Add special AP Setup Locked mode to allow read only ER.
358	    ap_setup_locked=2 can now be used to enable a special mode where
359	    WPS ER can learn the current AP settings, but cannot change them.
360	* WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2)
361	  - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool
362	    for testing protocol extensibility.
363	  - Add build option CONFIG_WPS_STRICT to allow disabling of WPS
364	    workarounds.
365	  - Add support for AuthorizedMACs attribute.
366	* TDLS:
367	  - Allow TDLS use or TDLS channel switching in the BSS to be
368	    prohibited in the BSS, using config params tdls_prohibit and
369	    tdls_prohibit_chan_switch.
370	* EAP server: Add support for configuring fragment size (see
371	  fragment_size in hostapd.conf).
372	* wlantest: Add a tool wlantest for IEEE802.11 protocol testing.
373	  wlantest can be used to capture frames from a monitor interface
374	  for realtime capturing or from pcap files for offline analysis.
375	* Interworking: Support added for 802.11u. Enable in .config with
376	  CONFIG_INTERWORKING. See hostapd.conf for config parameters for
377	  interworking.
378	* Android: Add build and runtime support for Android hostapd.
379	* Add a new debug message level for excessive information. Use
380	  -ddd to enable.
381	* TLS: Add support for tls_disable_time_checks=1 in client mode.
382	* Internal TLS:
383	  - Add support for TLS v1.1 (RFC 4346). Enable with build parameter
384	    CONFIG_TLSV11.
385	  - Add domainComponent parser for X.509 names
386	* Reorder some IEs to get closer to IEEE 802.11 standard. Move
387	  WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames.
388	  Move HT IEs to be later in (Re)Assoc Resp.
389	* Many bugfixes.

430	  allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y)
431	* EAP-FAST server: piggyback Phase 2 start with the end of Phase 1
432	* WPS: add support for dynamically selecting whether to provision the
433	  PSK as an ASCII passphrase or PSK
434	* added support for WDS (4-address frame) mode with per-station virtual
435	  interfaces (wds_sta=1 in config file; only supported with
436	  driver=nl80211 for now)
437	* fixed WPS Probe Request processing to handle missing required
438	  attribute
439	* fixed PKCS#12 use with OpenSSL 1.0.0
440	* detect bridge interface automatically so that bridge parameter in
441	  hostapd.conf becomes optional (though, it may now be used to
442	  automatically add then WLAN interface into a bridge with
443	  driver=nl80211)
444
4452009-11-21 - v0.7.0
446	* increased hostapd_cli ping interval to 5 seconds and made this
447	  configurable with a new command line options (-G<seconds>)
448	* driver_nl80211: use Linux socket filter to improve performance
449	* added support for external Registrars with WPS (UPnP transport)
450	* 802.11n: scan for overlapping BSSes before starting 20/40 MHz channel
451	* driver_nl80211: fixed STA accounting data collection (TX/RX bytes
452	  reported correctly; TX/RX packets not yet available from kernel)
453	* added support for WPS USBA out-of-band mechanism with USB Flash
454	  Drives (UFD) (CONFIG_WPS_UFD=y)
455	* fixed EAPOL/EAP reauthentication when using an external RADIUS
456	  authentication server
457	* fixed TNC with EAP-TTLS
458	* fixed IEEE 802.11r key derivation function to match with the standard
459	  (note: this breaks interoperability with previous version) [Bug 303]
460	* fixed SHA-256 based key derivation function to match with the
461	  standard when using CCMP (for IEEE 802.11r and IEEE 802.11w)
462	  (note: this breaks interoperability with previous version) [Bug 307]
463	* added number of code size optimizations to remove unnecessary
464	  functionality from the program binary based on build configuration
465	  (part of this automatic; part configurable with CONFIG_NO_* build
466	  options)
467	* use shared driver wrapper files with wpa_supplicant
468	* driver_nl80211: multiple updates to provide support for new Linux
469	  nl80211/mac80211 functionality
470	* updated management frame protection to use IEEE Std 802.11w-2009
471	* fixed number of small WPS issues and added workarounds to
472	  interoperate with common deployed broken implementations
473	* added some IEEE 802.11n co-existence rules to disable 40 MHz channels
474	  or modify primary/secondary channels if needed based on neighboring
475	  networks
476	* added support for NFC out-of-band mechanism with WPS
477	* added preliminary support for IEEE 802.11r RIC processing
478
4792009-01-06 - v0.6.7
480	* added support for Wi-Fi Protected Setup (WPS)
481	  (hostapd can now be configured to act as an integrated WPS Registrar
482	  and provision credentials for WPS Enrollees using PIN and PBC
483	  methods; external wireless Registrar can configure the AP, but
484	  external WLAN Manager Registrars are not supported); WPS support can
485	  be enabled by adding CONFIG_WPS=y into .config and setting the
486	  runtime configuration variables in hostapd.conf (see WPS section in
487	  the example configuration file); new hostapd_cli commands wps_pin and
488	  wps_pbc are used to configure WPS negotiation; see README-WPS for
489	  more details
490	* added IEEE 802.11n HT capability configuration (ht_capab)
491	* added support for generating Country IE based on nl80211 regulatory
492	  information (added if ieee80211d=1 in configuration)
493	* fixed WEP authentication (both Open System and Shared Key) with
494	  mac80211
495	* added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
496	* added support for using driver_test over UDP socket
497	* changed EAP-GPSK to use the IANA assigned EAP method type 51
498	* updated management frame protection to use IEEE 802.11w/D7.0
499	* fixed retransmission of EAP requests if no response is received
500
5012008-11-23 - v0.6.6
502	* added a new configuration option, wpa_ptk_rekey, that can be used to
503	  enforce frequent PTK rekeying, e.g., to mitigate some attacks against
504	  TKIP deficiencies
505	* updated OpenSSL code for EAP-FAST to use an updated version of the
506	  session ticket overriding API that was included into the upstream
507	  OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
508	  needed with that version anymore)
509	* changed channel flags configuration to read the information from
510	  the driver (e.g., via driver_nl80211 when using mac80211) instead of
511	  using hostapd as the source of the regulatory information (i.e.,
512	  information from CRDA is now used with mac80211); this allows 5 GHz
513	  channels to be used with hostapd (if allowed in the current
514	  regulatory domain)
515	* fixed EAP-TLS message processing for the last TLS message if it is
516	  large enough to require fragmentation (e.g., if a large Session
517	  Ticket data is included)
518	* fixed listen interval configuration for nl80211 drivers
519
5202008-11-01 - v0.6.5
521	* added support for SHA-256 as X.509 certificate digest when using the
522	  internal X.509/TLSv1 implementation
523	* fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer
524	  identity lengths)
525	* fixed internal TLSv1 implementation for abbreviated handshake (used
526	  by EAP-FAST server)
527	* added support for setting VLAN ID for STAs based on local MAC ACL
528	  (accept_mac_file) as an alternative for RADIUS server-based
529	  configuration
530	* updated management frame protection to use IEEE 802.11w/D6.0
531	  (adds a new association ping to protect against unauthenticated
532	  authenticate or (re)associate request frames dropping association)
533	* added support for using SHA256-based stronger key derivation for WPA2
534	  (IEEE 802.11w)
535	* added new "driver wrapper" for RADIUS-only configuration
536	  (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config)
537	* fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2)
538	  is enabled in configuration
539	* changed EAP-FAST configuration to use separate fields for A-ID and
540	  A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed
541	  16-octet len binary value for better interoperability with some peer
542	  implementations; eap_fast_a_id is now configured as a hex string
543	* driver_nl80211: Updated to match the current Linux mac80211 AP mode
544	  configuration (wireless-testing.git and Linux kernel releases
545	  starting from 2.6.29)
546
5472008-08-10 - v0.6.4
548	* added peer identity into EAP-FAST PAC-Opaque and skip Phase 2
549	  Identity Request if identity is already known
550	* added support for EAP Sequences in EAP-FAST Phase 2
551	* added support for EAP-TNC (Trusted Network Connect)
552	  (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST
553	  changes needed to run two methods in sequence (IF-T) and the IF-IMV
554	  and IF-TNCCS interfaces from TNCS)
555	* added support for optional cryptobinding with PEAPv0
556	* added fragmentation support for EAP-TNC
557	* added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled)
558	  data
559	* added support for opportunistic key caching (OKC)
560
5612008-02-22 - v0.6.3
562	* fixed Reassociation Response callback processing when using internal
563	  MLME (driver_{hostap,nl80211,test}.c)
564	* updated FT support to use the latest draft, IEEE 802.11r/D9.0
565	* copy optional Proxy-State attributes into RADIUS response when acting
566	  as a RADIUS authentication server
567	* fixed EAPOL state machine to handle a case in which no response is
568	  received from the RADIUS authentication server; previous version
569	  could have triggered a crash in some cases after a timeout
570	* fixed EAP-SIM/AKA realm processing to allow decorated usernames to
571	  be used
572	* added a workaround for EAP-SIM/AKA peers that include incorrect null
573	  termination in the username
574	* fixed EAP-SIM/AKA protected result indication to include AT_COUNTER
575	  attribute in notification messages only when using fast
576	  reauthentication
577	* fixed EAP-SIM Start response processing for fast reauthentication
578	  case
579	* added support for pending EAP processing in EAP-{PEAP,TTLS,FAST}
580	  phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method
581
5822008-01-01 - v0.6.2
583	* fixed EAP-SIM and EAP-AKA message parser to validate attribute
584	  lengths properly to avoid potential crash caused by invalid messages
585	* added data structure for storing allocated buffers (struct wpabuf);
586	  this does not affect hostapd usage, but many of the APIs changed
587	  and various interfaces (e.g., EAP) is not compatible with old
588	  versions
589	* added support for protecting EAP-AKA/Identity messages with
590	  AT_CHECKCODE (optional feature in RFC 4187)
591	* added support for protected result indication with AT_RESULT_IND for
592	  EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1)
593	* added support for configuring EAP-TTLS phase 2 non-EAP methods in
594	  EAP server configuration; previously all four were enabled for every
595	  phase 2 user, now all four are disabled by default and need to be
596	  enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP,
597	  TTLS-MSCHAPV2
598	* removed old debug printing mechanism and the related 'debug'
599	  parameter in the configuration file; debug verbosity is now set with
600	  -d (or -dd) command line arguments
601	* added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
602	  only shared key/password authentication is supported in this version
603
6042007-11-24 - v0.6.1
605	* added experimental, integrated TLSv1 server implementation with the
606	  needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
607	  setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
608	  .config); this can be useful, e.g., if the target system does not
609	  have a suitable TLS library and a minimal code size is required
610	* added support for EAP-FAST server method to the integrated EAP
611	  server
612	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
613	  draft (draft-ietf-emu-eap-gpsk-07.txt)
614	* added a new configuration parameter, rsn_pairwise, to allow different
615	  pairwise cipher suites to be enabled for WPA and RSN/WPA2
616	  (note: if wpa_pairwise differs from rsn_pairwise, the driver will
617	  either need to support this or will have to use the WPA/RSN IEs from
618	  hostapd; currently, the included madwifi and bsd driver interfaces do
619	  not have support for this)
620	* updated FT support to use the latest draft, IEEE 802.11r/D8.0
621
6222007-05-28 - v0.6.0
623	* added experimental IEEE 802.11r/D6.0 support
624	* updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
625	* updated EAP-PSK to use the IANA-allocated EAP type 47
626	* fixed EAP-PSK bit ordering of the Flags field
627	* fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
628	  by reading wpa_psk_file [Bug 181]
629	* fixed EAP-TTLS AVP parser processing for too short AVP lengths
630	* fixed IPv6 connection to RADIUS accounting server
631	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
632	  draft (draft-ietf-emu-eap-gpsk-04.txt)
633	* hlr_auc_gw: read GSM triplet file into memory and rotate through the
634	  entries instead of only using the same three triplets every time
635	  (this does not work properly with tests using multiple clients, but
636	  provides bit better triplet data for testing a single client; anyway,
637	  if a better quality triplets are needed, GSM-Milenage should be used
638	  instead of hardcoded triplet file)
639	* fixed EAP-MSCHAPv2 server to use a space between S and M parameters
640	  in Success Request [Bug 203]
641	* added support for sending EAP-AKA Notifications in error cases
642	* updated to use IEEE 802.11w/D2.0 for management frame protection
643	  (still experimental)
644	* RADIUS server: added support for processing duplicate messages
645	  (retransmissions from RADIUS client) by replying with the previous
646	  reply
647
6482006-11-24 - v0.5.6
649	* added support for configuring and controlling multiple BSSes per
650	  radio interface (bss=<ifname> in hostapd.conf); this is only
651	  available with Devicescape and test driver interfaces
652	* fixed PMKSA cache update in the end of successful RSN
653	  pre-authentication
654	* added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
655	  for each STA based on RADIUS Access-Accept attributes); this requires
656	  VLAN support from the kernel driver/802.11 stack and this is
657	  currently only available with Devicescape and test driver interfaces
658	* driver_madwifi: fixed configuration of unencrypted modes (plaintext
659	  and IEEE 802.1X without WEP)
660	* removed STAKey handshake since PeerKey handshake has replaced it in
661	  IEEE 802.11ma and there are no known deployments of STAKey
662	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
663	  draft (draft-ietf-emu-eap-gpsk-01.txt)
664	* added preliminary implementation of IEEE 802.11w/D1.0 (management
665	  frame protection)
666	  (Note: this requires driver support to work properly.)
667	  (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
668	* hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
669	* hlr_auc_gw: added support for reading per-IMSI Milenage keys and
670	  parameters from a text file to make it possible to implement proper
671	  GSM/UMTS authentication server for multiple SIM/USIM cards using
672	  EAP-SIM/EAP-AKA
673	* fixed session timeout processing with drivers that do not use
674	  ieee802_11.c (e.g., madwifi)
675
6762006-08-27 - v0.5.5
677	* added 'hostapd_cli new_sta <addr>' command for adding a new STA into
678	  hostapd (e.g., to initialize wired network authentication based on an
679	  external signal)
680	* fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
681	  using WPA2 even if PMKSA caching is not used
682	* added -P<pid file> argument for hostapd to write the current process
683	  id into a file
684	* added support for RADIUS Authentication Server MIB (RFC 2619)
685
6862006-06-20 - v0.5.4
687	* fixed nt_password_hash build [Bug 144]
688	* added PeerKey handshake implementation for IEEE 802.11e
689	  direct link setup (DLS) to replace STAKey handshake
690	* added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
691	  draft-clancy-emu-eap-shared-secret-00.txt)
692	* fixed a segmentation fault when RSN pre-authentication was completed
693	  successfully [Bug 152]
694
6952006-04-27 - v0.5.3
696	* do not build nt_password_hash and hlr_auc_gw by default to avoid
697	  requiring a TLS library for a successful build; these programs can be
698	  build with 'make nt_password_hash' and 'make hlr_auc_gw'
699	* added a new configuration option, eapol_version, that can be used to
700	  set EAPOL version to 1 (default is 2) to work around broken client
701	  implementations that drop EAPOL frames which use version number 2
702	  [Bug 89]
703	* added support for EAP-SAKE (no EAP method number allocated yet, so
704	  this is using the same experimental type 255 as EAP-PSK)
705	* fixed EAP-MSCHAPv2 message length validation
706
7072006-03-19 - v0.5.2
708	* fixed stdarg use in hostapd_logger(): if both stdout and syslog
709	  logging was enabled, hostapd could trigger a segmentation fault in
710	  vsyslog on some CPU -- C library combinations
711	* moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
712	  program to make it easier to use for implementing real SS7 gateway;
713	  eap_sim_db is not anymore used as a file name for GSM authentication
714	  triplets; instead, it is path to UNIX domain socket that will be used
715	  to communicate with the external gateway program (e.g., hlr_auc_gw)
716	* added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
717	  local information (GSM authentication triplets from a text file and
718	  hardcoded AKA authentication data); this can be used to test EAP-SIM
719	  and EAP-AKA
720	* added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
721	  to make it possible to test EAP-AKA with real USIM cards (this is
722	  disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
723	  to enable this)
724	* driver_madwifi: added support for getting station RSN IE from
725	  madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
726	  broken with earlier change (r1357) in the driver
727	* changed EAP method registration to use a dynamic list of methods
728	  instead of a static list generated at build time
729	* fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
730	  [Bug 125]
731	* added ap_max_inactivity configuration parameter
732
7332006-01-29 - v0.5.1
734	* driver_test: added better support for multiple APs and STAs by using
735	  a directory with sockets that include MAC address for each device in
736	  the name (test_socket=DIR:/tmp/test)
737	* added support for EAP expanded type (vendor specific EAP methods)
738
7392005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
740	* added experimental STAKey handshake implementation for IEEE 802.11e
741	  direct link setup (DLS); note: this is disabled by default in both
742	  build and runtime configuration (can be enabled with CONFIG_STAKEY=y
743	  and stakey=1)
744	* added support for EAP methods to use callbacks to external programs
745	  by buffering a pending request and processing it after the EAP method
746	  is ready to continue
747	* improved EAP-SIM database interface to allow external request to GSM
748	  HLR/AuC without blocking hostapd process
749	* added support for using EAP-SIM pseudonyms and fast re-authentication
750	* added support for EAP-AKA in the integrated EAP authenticator
751	* added support for matching EAP identity prefixes (e.g., "1"*) in EAP
752	  user database to allow EAP-SIM/AKA selection without extra roundtrip
753	  for EAP-Nak negotiation
754	* added support for storing EAP user password as NtPasswordHash instead
755	  of plaintext password when using MSCHAP or MSCHAPv2 for
756	  authentication (hash:<16-octet hex value>); added nt_password_hash
757	  tool for hashing password to generate NtPasswordHash
758
7592005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
760	* driver_wired: fixed EAPOL sending to optionally use PAE group address
761	  as the destination instead of supplicant MAC address; this is
762	  disabled by default, but should be enabled with use_pae_group_addr=1
763	  in configuration file if the wired interface is used by only one
764	  device at the time (common switch configuration)
765	* driver_madwifi: configure driver to use TKIP countermeasures in order
766	  to get correct behavior (IEEE 802.11 association failing; previously,
767	  association succeeded, but hostpad forced disassociation immediately)
768	* driver_madwifi: added support for madwifi-ng
769
7702005-10-27 - v0.4.6
771	* added support for replacing user identity from EAP with RADIUS
772	  User-Name attribute from Access-Accept message, if that is included,
773	  for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
774	  tunneled identity into accounting messages when the RADIUS server
775	  does not support better way of doing this with Class attribute)
776	* driver_madwifi: fixed EAPOL packet receive for configuration where
777	  ath# is part of a bridge interface
778	* added a configuration file and log analyzer script for logwatch
779	* fixed EAPOL state machine step function to process all state
780	  transitions before processing new events; this resolves a race
781	  condition in which EAPOL-Start message could trigger hostapd to send
782	  two EAP-Response/Identity frames to the authentication server
783
7842005-09-25 - v0.4.5
785	* added client CA list to the TLS certificate request in order to make
786	  it easier for the client to select which certificate to use
787	* added experimental support for EAP-PSK
788	* added support for WE-19 (hostap, madwifi)
789
7902005-08-21 - v0.4.4
791	* fixed build without CONFIG_RSN_PREAUTH
792	* fixed FreeBSD build
793
7942005-06-26 - v0.4.3
795	* fixed PMKSA caching to copy User-Name and Class attributes so that
796	  RADIUS accounting gets correct information
797	* start RADIUS accounting only after successful completion of WPA
798	  4-Way Handshake if WPA-PSK is used
799	* fixed PMKSA caching for the case where STA (re)associates without
800	  first disassociating
801
8022005-06-12 - v0.4.2
803	* EAP-PAX is now registered as EAP type 46
804	* fixed EAP-PAX MAC calculation
805	* fixed EAP-PAX CK and ICK key derivation
806	* renamed eap_authenticator configuration variable to eap_server to
807	  better match with RFC 3748 (EAP) terminology
808	* driver_test: added support for testing hostapd with wpa_supplicant
809	  by using test driver interface without any kernel drivers or network
810	  cards
811
8122005-05-22 - v0.4.1
813	* fixed RADIUS server initialization when only auth or acct server
814	  is configured and the other one is left empty
815	* driver_madwifi: added support for RADIUS accounting
816	* driver_madwifi: added preliminary support for compiling against 'BSD'
817	  branch of madwifi CVS tree
818	* driver_madwifi: fixed pairwise key removal to allow WPA reauth
819	  without disassociation
820	* added support for reading additional certificates from PKCS#12 files
821	  and adding them to the certificate chain
822	* fixed RADIUS Class attribute processing to only use Access-Accept
823	  packets to update Class; previously, other RADIUS authentication
824	  packets could have cleared Class attribute
825	* added support for more than one Class attribute in RADIUS packets
826	* added support for verifying certificate revocation list (CRL) when
827	  using integrated EAP authenticator for EAP-TLS; new hostapd.conf
828	  options 'check_crl'; CRL must be included in the ca_cert file for now
829
8302005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
831	* added support for including network information into
832	  EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
833	  (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
834	* fixed a bug which caused some RSN pre-authentication cases to use
835	  freed memory and potentially crash hostapd
836	* fixed private key loading for cases where passphrase is not set
837	* added support for sending TLS alerts and aborting authentication
838	  when receiving a TLS alert
839	* fixed WPA2 to add PMKSA cache entry when using integrated EAP
840	  authenticator
841	* fixed PMKSA caching (EAP authentication was not skipped correctly
842	  with the new state machine changes from IEEE 802.1X draft)
843	* added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
844	  and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
845	  to be added to .config to include IPv6 support); for RADIUS server,
846	  radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
847	  in RADIUS clients file can then use IPv6 format
848	* added experimental support for EAP-PAX
849	* replaced hostapd control interface library (hostapd_ctrl.[ch]) with
850	  the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
851
8522005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
853
8542005-01-23 - v0.3.5
855	* added support for configuring a forced PEAP version based on the
856	  Phase 1 identity
857	* fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
858	  to terminate authentication
859	* fixed EAP identifier duplicate processing with the new IEEE 802.1X
860	  draft
861	* clear accounting data in the driver when starting a new accounting
862	  session
863	* driver_madwifi: filter wireless events based on ifindex to allow more
864	  than one network interface to be used
865	* fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
866	  setting if the packet does not pass MIC verification (e.g., due to
867	  incorrect PSK); previously, message 1/4 was not tried again if an
868	  invalid message 2/4 was received
869	* fixed reconfiguration of RADIUS client retransmission timer when
870	  adding a new message to the pending list; previously, timer was not
871	  updated at this point and if there was a pending message with long
872	  time for the next retry, the new message needed to wait that long for
873	  its first retry, too
874
8752005-01-09 - v0.3.4
876	* added support for configuring multiple allowed EAP types for Phase 2
877	  authentication (EAP-PEAP, EAP-TTLS)
878	* fixed EAPOL-Start processing to trigger WPA reauthentication
879	  (previously, only EAPOL authentication was done)
880
8812005-01-02 - v0.3.3
882	* added support for EAP-PEAP in the integrated EAP authenticator
883	* added support for EAP-GTC in the integrated EAP authenticator
884	* added support for configuring list of EAP methods for Phase 1 so that
885	  the integrated EAP authenticator can, e.g., use the wildcard entry
886	  for EAP-TLS and EAP-PEAP
887	* added support for EAP-TTLS in the integrated EAP authenticator
888	* added support for EAP-SIM in the integrated EAP authenticator
889	* added support for using hostapd as a RADIUS authentication server
890	  with the integrated EAP authenticator taking care of EAP
891	  authentication (new hostapd.conf options: radius_server_clients and
892	  radius_server_auth_port); this is not included in default build; use
893	  CONFIG_RADIUS_SERVER=y in .config to include
894
8952004-12-19 - v0.3.2
896	* removed 'daemonize' configuration file option since it has not really
897	  been used at all for more than year
898	* driver_madwifi: fixed group key setup and added get_ssid method
899	* added support for EAP-MSCHAPv2 in the integrated EAP authenticator
900
9012004-12-12 - v0.3.1
902	* added support for integrated EAP-TLS authentication (new hostapd.conf
903	  variables: ca_cert, server_cert, private_key, private_key_passwd);
904	  this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
905	  external RADIUS server
906	* added support for reading PKCS#12 (PFX) files (as a replacement for
907	  PEM/DER) to get certificate and private key (CONFIG_PKCS12)
908
9092004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
910	* added support for Acct-{Input,Output}-Gigawords
911	* added support for Event-Timestamp (in RADIUS Accounting-Requests)
912	* added support for RADIUS Authentication Client MIB (RFC2618)
913	* added support for RADIUS Accounting Client MIB (RFC2620)
914	* made EAP re-authentication period configurable (eap_reauth_period)
915	* fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
916	* fixed EAPOL state machine to stop if STA is removed during
917	  eapol_sm_step(); this fixes at least one segfault triggering bug with
918	  IEEE 802.11i pre-authentication
919	* added support for multiple WPA pre-shared keys (e.g., one for each
920	  client MAC address or keys shared by a group of clients);
921	  new hostapd.conf field wpa_psk_file for setting path to a text file
922	  containing PSKs, see hostapd.wpa_psk for an example
923	* added support for multiple driver interfaces to allow hostapd to be
924	  used with other drivers
925	* added wired authenticator driver interface (driver=wired in
926	  hostapd.conf, see wired.conf for example configuration)
927	* added madwifi driver interface (driver=madwifi in hostapd.conf, see
928	  madwifi.conf for example configuration; Note: include files from
929	  madwifi project is needed for building and a configuration file,
930	  .config, needs to be created in hostapd directory with
931	  CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
932	  build)
933	* fixed an alignment issue that could cause SHA-1 to fail on some
934	  platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
935	  align variables)
936	* fixed RADIUS reconnection after an error in sending interim
937	  accounting packets
938	* added hostapd control interface for external programs and an example
939	  CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
940	* started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
941	  'hostapd_cli sta <addr>')
942	* finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
943	* added support for strict GTK rekeying (wpa_strict_rekey in
944	  hostapd.conf)
945	* updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
946	  (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
947	  IEEE 802.11F-2003)
948	* added Prism54 driver interface (driver=prism54 in hostapd.conf;
949	  note: .config needs to be created in hostapd directory with
950	  CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
951	  build)
952	* dual-licensed hostapd (GPLv2 and BSD licenses)
953	* fixed RADIUS accounting to generate a new session id for cases where
954	  a station reassociates without first being complete deauthenticated
955	* fixed STA disassociation handler to mark next timeout state to
956	  deauthenticate the station, i.e., skip long wait for inactivity poll
957	  and extra disassociation, if the STA disassociates without
958	  deauthenticating
959	* added integrated EAP authenticator that can be used instead of
960	  external RADIUS authentication server; currently, only EAP-MD5 is
961	  supported, so this cannot yet be used for key distribution; the EAP
962	  method interface is generic, though, so adding new EAP methods should
963	  be straightforward; new hostapd.conf variables: 'eap_authenticator'
964	  and 'eap_user_file'; this obsoletes "minimal authentication server"
965	  ('minimal_eap' in hostapd.conf) which is now removed
966	* added support for FreeBSD and driver interface for the BSD net80211
967	  layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
968	  .config); please note that some of the required kernel mods have not
969	  yet been committed
970
9712004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
972	* fixed some accounting cases where Accounting-Start was sent when
973	  IEEE 802.1X port was being deauthorized
974
9752004-06-20 - v0.2.3
976	* modified RADIUS client to re-connect the socket in case of certain
977	  error codes that are generated when a network interface state is
978	  changes (e.g., when IP address changes or the interface is set UP)
979	* fixed couple of cases where EAPOL state for a station was freed
980	  twice causing a segfault for hostapd
981	* fixed couple of bugs in processing WPA deauthentication (freed data
982	  was used)
983
9842004-05-31 - v0.2.2
985	* fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
986	* fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
987	  cases where STAs dropped multicast frames as replay attacks
988	* added support for copying RADIUS Attribute 'Class' from
989	  authentication messages into accounting messages
990	* send canned EAP failure if RADIUS server sends Access-Reject without
991	  EAP message (previously, Supplicant was not notified in this case)
992	* fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
993	  not start EAPOL state machines if the STA selected to use WPA-PSK)
994
9952004-05-06 - v0.2.1
996	* added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
997	  - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
998	    (i.e., IEEE 802.11i/D3.0)
999	  - supports WPA-only, RSN-only, and mixed WPA/RSN mode
1000	  - both WPA-PSK and WPA-RADIUS/EAP are supported
1001	  - PMKSA caching and pre-authentication
1002	  - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
1003	    wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
1004	    rsn_preauth, rsn_preauth_interfaces
1005	* fixed interim accounting to remove any pending accounting messages
1006	  to the STA before sending a new one
1007
10082004-02-15 - v0.2.0
1009	* added support for Acct-Interim-Interval:
1010	  - draft-ietf-radius-acct-interim-01.txt
1011	  - use Acct-Interim-Interval attribute from Access-Accept if local
1012	    'radius_acct_interim_interval' is not set
1013	  - allow different update intervals for each STA
1014	* fixed event loop to call signal handlers only after returning from
1015	  the real signal handler
1016	* reset sta->timeout_next after successful association to make sure
1017	  that the previously registered inactivity timer will not remove the
1018	  STA immediately (e.g., if STA deauthenticates and re-associates
1019	  before the timer is triggered).
1020	* added new hostapd.conf variable, nas_identifier, that can be used to
1021	  add an optional RADIUS Attribute, NAS-Identifier, into authentication
1022	  and accounting messages
1023	* added support for Accounting-On and Accounting-Off messages
1024	* fixed accounting session handling to send Accounting-Start only once
1025	  per session and not to send Accounting-Stop if the session was not
1026	  initialized properly
1027	* fixed Accounting-Stop statistics in cases where the message was
1028	  previously sent after the kernel entry for the STA (and/or IEEE
1029	  802.1X data) was removed
1030
1031
