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

252	* bsd: Add support for setting HT values in IFM_MMASK.
253	* Allow client isolation to be configured with ap_isolate. Client
254	  isolation can be used to prevent low-level bridging of frames
255	  between associated stations in the BSS. By default, this bridging
256	  is allowed.
257	* Allow coexistance of HT BSSes with WEP/TKIP BSSes.

261	* Add support for writing debug log to a file using "-f" option. Also
262	  add relog CLI command to re-open the log file.
263	* Add bridge handling for WDS STA interfaces. By default they are
264	  added to the configured bridge of the AP interface (if present),
265	  but the user can also specify a separate bridge using cli command
266	  wds_bridge.
267	* hostapd_cli:
268	  - Add wds_bridge command for specifying bridge for WDS STA
269	    interfaces.
270	  - Add relog command for reopening log file.
271	  - Send AP-STA-DISCONNECTED event when an AP disconnects a station
272	    due to inactivity.
273	  - Add wps_config ctrl_interface command for configuring AP. This
274	    command can be used to configure the AP using the internal WPS
275	    registrar. It works in the same way as new AP settings received
276	    from an ER.
277	  - Many WPS/WPS ER commands - see WPS/WPS ER sections for details.
278	  - Add command get version, that returns hostapd version string.
279	* WNM: Add BSS Transition Management Request for ESS Disassoc Imminent.
280	  Use hostapd_cli ess_disassoc (STA addr) (URL) to send the
281	  notification to the STA.
282	* Allow AP mode to disconnect STAs based on low ACK condition (when
283	  the data connection is not working properly, e.g., due to the STA
284	  going outside the range of the AP). Disabled by default, enable by
285	  config option disassoc_low_ack.
286	* Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad
287	  config file.
288	* WPS:
289	  - Send AP Settings as a wrapped Credential attribute to ctrl_iface
290	    in WPS-NEW-AP-SETTINGS.
291	  - Dispatch more WPS events through hostapd ctrl_iface.
292	  - Add mechanism for indicating non-standard WPS errors.
293	  - Change concurrent radio AP to use only one WPS UPnP instance.
294	  - Add wps_check_pin command for processing PIN from user input.
295	    UIs can use this command to process a PIN entered by a user and to
296	    validate the checksum digit (if present).
297	  - Add hostap_cli get_config command to display current AP config.
298	  - Add new hostapd_cli command, wps_ap_pin, to manage AP PIN at
299	    runtime and support dynamic AP PIN management.
300	  - Disable AP PIN after 10 consecutive failures. Slow down attacks
301	    on failures up to 10.
302	  - Allow AP to start in Enrollee mode without AP PIN for probing,
303	    to be compatible with Windows 7.
304	  - Add Config Error into WPS-FAIL events to provide more info
305	    to the user on how to resolve the issue.
306	  - When controlling multiple interfaces:
307	     - apply WPS commands to all interfaces configured to use WPS
308	     - apply WPS config changes to all interfaces that use WPS
309	     - when an attack is detected on any interface, disable AP PIN on
310	       all interfaces
311	* WPS ER:
312	  - Show SetSelectedRegistrar events as ctrl_iface events.
313	  - Add special AP Setup Locked mode to allow read only ER.
314	    ap_setup_locked=2 can now be used to enable a special mode where
315	    WPS ER can learn the current AP settings, but cannot change them.
316	* WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2)
317	  - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool
318	    for testing protocol extensibility.
319	  - Add build option CONFIG_WPS_STRICT to allow disabling of WPS
320	    workarounds.
321	  - Add support for AuthorizedMACs attribute.
322	* TDLS:
323	  - Allow TDLS use or TDLS channel switching in the BSS to be
324	    prohibited in the BSS, using config params tdls_prohibit and
325	    tdls_prohibit_chan_switch.
326	* EAP server: Add support for configuring fragment size (see
327	  fragment_size in hostapd.conf).
328	* wlantest: Add a tool wlantest for IEEE802.11 protocol testing.
329	  wlantest can be used to capture frames from a monitor interface
330	  for realtime capturing or from pcap files for offline analysis.
331	* Interworking: Support added for 802.11u. Enable in .config with
332	  CONFIG_INTERWORKING. See hostapd.conf for config parameters for
333	  interworking.
334	* Android: Add build and runtime support for Android hostapd.
335	* Add a new debug message level for excessive information. Use
336	  -ddd to enable.

339	  - Add support for TLS v1.1 (RFC 4346). Enable with build parameter
340	    CONFIG_TLSV11.
341	  - Add domainComponent parser for X.509 names
342	* Reorder some IEs to get closer to IEEE 802.11 standard. Move
343	  WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames.
344	  Move HT IEs to be later in (Re)Assoc Resp.
345	* Many bugfixes.

428	  interoperate with common deployed broken implementations
429	* added some IEEE 802.11n co-existence rules to disable 40 MHz channels
430	  or modify primary/secondary channels if needed based on neighboring
431	  networks
432	* added support for NFC out-of-band mechanism with WPS
433	* added preliminary support for IEEE 802.11r RIC processing
434
4352009-01-06 - v0.6.7
436	* added support for Wi-Fi Protected Setup (WPS)
437	  (hostapd can now be configured to act as an integrated WPS Registrar
438	  and provision credentials for WPS Enrollees using PIN and PBC
439	  methods; external wireless Registrar can configure the AP, but
440	  external WLAN Manager Registrars are not supported); WPS support can
441	  be enabled by adding CONFIG_WPS=y into .config and setting the
442	  runtime configuration variables in hostapd.conf (see WPS section in
443	  the example configuration file); new hostapd_cli commands wps_pin and
444	  wps_pbc are used to configure WPS negotiation; see README-WPS for
445	  more details
446	* added IEEE 802.11n HT capability configuration (ht_capab)
447	* added support for generating Country IE based on nl80211 regulatory
448	  information (added if ieee80211d=1 in configuration)
449	* fixed WEP authentication (both Open System and Shared Key) with
450	  mac80211
451	* added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
452	* added support for using driver_test over UDP socket
453	* changed EAP-GPSK to use the IANA assigned EAP method type 51
454	* updated management frame protection to use IEEE 802.11w/D7.0
455	* fixed retransmission of EAP requests if no response is received
456
4572008-11-23 - v0.6.6
458	* added a new configuration option, wpa_ptk_rekey, that can be used to
459	  enforce frequent PTK rekeying, e.g., to mitigate some attacks against
460	  TKIP deficiencies
461	* updated OpenSSL code for EAP-FAST to use an updated version of the
462	  session ticket overriding API that was included into the upstream
463	  OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
464	  needed with that version anymore)
465	* changed channel flags configuration to read the information from
466	  the driver (e.g., via driver_nl80211 when using mac80211) instead of
467	  using hostapd as the source of the regulatory information (i.e.,
468	  information from CRDA is now used with mac80211); this allows 5 GHz
469	  channels to be used with hostapd (if allowed in the current
470	  regulatory domain)
471	* fixed EAP-TLS message processing for the last TLS message if it is
472	  large enough to require fragmentation (e.g., if a large Session
473	  Ticket data is included)
474	* fixed listen interval configuration for nl80211 drivers
475
4762008-11-01 - v0.6.5
477	* added support for SHA-256 as X.509 certificate digest when using the
478	  internal X.509/TLSv1 implementation
479	* fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer
480	  identity lengths)
481	* fixed internal TLSv1 implementation for abbreviated handshake (used
482	  by EAP-FAST server)
483	* added support for setting VLAN ID for STAs based on local MAC ACL
484	  (accept_mac_file) as an alternative for RADIUS server-based
485	  configuration
486	* updated management frame protection to use IEEE 802.11w/D6.0
487	  (adds a new association ping to protect against unauthenticated
488	  authenticate or (re)associate request frames dropping association)
489	* added support for using SHA256-based stronger key derivation for WPA2
490	  (IEEE 802.11w)
491	* added new "driver wrapper" for RADIUS-only configuration
492	  (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config)
493	* fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2)
494	  is enabled in configuration
495	* changed EAP-FAST configuration to use separate fields for A-ID and
496	  A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed
497	  16-octet len binary value for better interoperability with some peer
498	  implementations; eap_fast_a_id is now configured as a hex string
499	* driver_nl80211: Updated to match the current Linux mac80211 AP mode
500	  configuration (wireless-testing.git and Linux kernel releases
501	  starting from 2.6.29)
502
5032008-08-10 - v0.6.4
504	* added peer identity into EAP-FAST PAC-Opaque and skip Phase 2
505	  Identity Request if identity is already known
506	* added support for EAP Sequences in EAP-FAST Phase 2
507	* added support for EAP-TNC (Trusted Network Connect)
508	  (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST
509	  changes needed to run two methods in sequence (IF-T) and the IF-IMV
510	  and IF-TNCCS interfaces from TNCS)
511	* added support for optional cryptobinding with PEAPv0
512	* added fragmentation support for EAP-TNC
513	* added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled)
514	  data
515	* added support for opportunistic key caching (OKC)
516
5172008-02-22 - v0.6.3
518	* fixed Reassociation Response callback processing when using internal
519	  MLME (driver_{hostap,nl80211,test}.c)
520	* updated FT support to use the latest draft, IEEE 802.11r/D9.0
521	* copy optional Proxy-State attributes into RADIUS response when acting
522	  as a RADIUS authentication server
523	* fixed EAPOL state machine to handle a case in which no response is
524	  received from the RADIUS authentication server; previous version
525	  could have triggered a crash in some cases after a timeout
526	* fixed EAP-SIM/AKA realm processing to allow decorated usernames to
527	  be used
528	* added a workaround for EAP-SIM/AKA peers that include incorrect null
529	  termination in the username
530	* fixed EAP-SIM/AKA protected result indication to include AT_COUNTER
531	  attribute in notification messages only when using fast
532	  reauthentication
533	* fixed EAP-SIM Start response processing for fast reauthentication
534	  case
535	* added support for pending EAP processing in EAP-{PEAP,TTLS,FAST}
536	  phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method
537
5382008-01-01 - v0.6.2
539	* fixed EAP-SIM and EAP-AKA message parser to validate attribute
540	  lengths properly to avoid potential crash caused by invalid messages
541	* added data structure for storing allocated buffers (struct wpabuf);
542	  this does not affect hostapd usage, but many of the APIs changed
543	  and various interfaces (e.g., EAP) is not compatible with old
544	  versions
545	* added support for protecting EAP-AKA/Identity messages with
546	  AT_CHECKCODE (optional feature in RFC 4187)
547	* added support for protected result indication with AT_RESULT_IND for
548	  EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1)
549	* added support for configuring EAP-TTLS phase 2 non-EAP methods in
550	  EAP server configuration; previously all four were enabled for every
551	  phase 2 user, now all four are disabled by default and need to be
552	  enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP,
553	  TTLS-MSCHAPV2
554	* removed old debug printing mechanism and the related 'debug'
555	  parameter in the configuration file; debug verbosity is now set with
556	  -d (or -dd) command line arguments
557	* added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
558	  only shared key/password authentication is supported in this version
559
5602007-11-24 - v0.6.1
561	* added experimental, integrated TLSv1 server implementation with the
562	  needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
563	  setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
564	  .config); this can be useful, e.g., if the target system does not
565	  have a suitable TLS library and a minimal code size is required
566	* added support for EAP-FAST server method to the integrated EAP
567	  server
568	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
569	  draft (draft-ietf-emu-eap-gpsk-07.txt)
570	* added a new configuration parameter, rsn_pairwise, to allow different
571	  pairwise cipher suites to be enabled for WPA and RSN/WPA2
572	  (note: if wpa_pairwise differs from rsn_pairwise, the driver will
573	  either need to support this or will have to use the WPA/RSN IEs from
574	  hostapd; currently, the included madwifi and bsd driver interfaces do
575	  not have support for this)
576	* updated FT support to use the latest draft, IEEE 802.11r/D8.0
577
5782007-05-28 - v0.6.0
579	* added experimental IEEE 802.11r/D6.0 support
580	* updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
581	* updated EAP-PSK to use the IANA-allocated EAP type 47
582	* fixed EAP-PSK bit ordering of the Flags field
583	* fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
584	  by reading wpa_psk_file [Bug 181]
585	* fixed EAP-TTLS AVP parser processing for too short AVP lengths
586	* fixed IPv6 connection to RADIUS accounting server
587	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
588	  draft (draft-ietf-emu-eap-gpsk-04.txt)
589	* hlr_auc_gw: read GSM triplet file into memory and rotate through the
590	  entries instead of only using the same three triplets every time
591	  (this does not work properly with tests using multiple clients, but
592	  provides bit better triplet data for testing a single client; anyway,
593	  if a better quality triplets are needed, GSM-Milenage should be used
594	  instead of hardcoded triplet file)
595	* fixed EAP-MSCHAPv2 server to use a space between S and M parameters
596	  in Success Request [Bug 203]
597	* added support for sending EAP-AKA Notifications in error cases
598	* updated to use IEEE 802.11w/D2.0 for management frame protection
599	  (still experimental)
600	* RADIUS server: added support for processing duplicate messages
601	  (retransmissions from RADIUS client) by replying with the previous
602	  reply
603
6042006-11-24 - v0.5.6
605	* added support for configuring and controlling multiple BSSes per
606	  radio interface (bss=<ifname> in hostapd.conf); this is only
607	  available with Devicescape and test driver interfaces
608	* fixed PMKSA cache update in the end of successful RSN
609	  pre-authentication
610	* added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
611	  for each STA based on RADIUS Access-Accept attributes); this requires
612	  VLAN support from the kernel driver/802.11 stack and this is
613	  currently only available with Devicescape and test driver interfaces
614	* driver_madwifi: fixed configuration of unencrypted modes (plaintext
615	  and IEEE 802.1X without WEP)
616	* removed STAKey handshake since PeerKey handshake has replaced it in
617	  IEEE 802.11ma and there are no known deployments of STAKey
618	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
619	  draft (draft-ietf-emu-eap-gpsk-01.txt)
620	* added preliminary implementation of IEEE 802.11w/D1.0 (management
621	  frame protection)
622	  (Note: this requires driver support to work properly.)
623	  (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
624	* hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
625	* hlr_auc_gw: added support for reading per-IMSI Milenage keys and
626	  parameters from a text file to make it possible to implement proper
627	  GSM/UMTS authentication server for multiple SIM/USIM cards using
628	  EAP-SIM/EAP-AKA
629	* fixed session timeout processing with drivers that do not use
630	  ieee802_11.c (e.g., madwifi)
631
6322006-08-27 - v0.5.5
633	* added 'hostapd_cli new_sta <addr>' command for adding a new STA into
634	  hostapd (e.g., to initialize wired network authentication based on an
635	  external signal)
636	* fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
637	  using WPA2 even if PMKSA caching is not used
638	* added -P<pid file> argument for hostapd to write the current process
639	  id into a file
640	* added support for RADIUS Authentication Server MIB (RFC 2619)
641
6422006-06-20 - v0.5.4
643	* fixed nt_password_hash build [Bug 144]
644	* added PeerKey handshake implementation for IEEE 802.11e
645	  direct link setup (DLS) to replace STAKey handshake
646	* added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
647	  draft-clancy-emu-eap-shared-secret-00.txt)
648	* fixed a segmentation fault when RSN pre-authentication was completed
649	  successfully [Bug 152]
650
6512006-04-27 - v0.5.3
652	* do not build nt_password_hash and hlr_auc_gw by default to avoid
653	  requiring a TLS library for a successful build; these programs can be
654	  build with 'make nt_password_hash' and 'make hlr_auc_gw'
655	* added a new configuration option, eapol_version, that can be used to
656	  set EAPOL version to 1 (default is 2) to work around broken client
657	  implementations that drop EAPOL frames which use version number 2
658	  [Bug 89]
659	* added support for EAP-SAKE (no EAP method number allocated yet, so
660	  this is using the same experimental type 255 as EAP-PSK)
661	* fixed EAP-MSCHAPv2 message length validation
662
6632006-03-19 - v0.5.2
664	* fixed stdarg use in hostapd_logger(): if both stdout and syslog
665	  logging was enabled, hostapd could trigger a segmentation fault in
666	  vsyslog on some CPU -- C library combinations
667	* moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
668	  program to make it easier to use for implementing real SS7 gateway;
669	  eap_sim_db is not anymore used as a file name for GSM authentication
670	  triplets; instead, it is path to UNIX domain socket that will be used
671	  to communicate with the external gateway program (e.g., hlr_auc_gw)
672	* added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
673	  local information (GSM authentication triplets from a text file and
674	  hardcoded AKA authentication data); this can be used to test EAP-SIM
675	  and EAP-AKA
676	* added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
677	  to make it possible to test EAP-AKA with real USIM cards (this is
678	  disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
679	  to enable this)
680	* driver_madwifi: added support for getting station RSN IE from
681	  madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
682	  broken with earlier change (r1357) in the driver
683	* changed EAP method registration to use a dynamic list of methods
684	  instead of a static list generated at build time
685	* fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
686	  [Bug 125]
687	* added ap_max_inactivity configuration parameter
688
6892006-01-29 - v0.5.1
690	* driver_test: added better support for multiple APs and STAs by using
691	  a directory with sockets that include MAC address for each device in
692	  the name (test_socket=DIR:/tmp/test)
693	* added support for EAP expanded type (vendor specific EAP methods)
694
6952005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
696	* added experimental STAKey handshake implementation for IEEE 802.11e
697	  direct link setup (DLS); note: this is disabled by default in both
698	  build and runtime configuration (can be enabled with CONFIG_STAKEY=y
699	  and stakey=1)
700	* added support for EAP methods to use callbacks to external programs
701	  by buffering a pending request and processing it after the EAP method
702	  is ready to continue
703	* improved EAP-SIM database interface to allow external request to GSM
704	  HLR/AuC without blocking hostapd process
705	* added support for using EAP-SIM pseudonyms and fast re-authentication
706	* added support for EAP-AKA in the integrated EAP authenticator
707	* added support for matching EAP identity prefixes (e.g., "1"*) in EAP
708	  user database to allow EAP-SIM/AKA selection without extra roundtrip
709	  for EAP-Nak negotiation
710	* added support for storing EAP user password as NtPasswordHash instead
711	  of plaintext password when using MSCHAP or MSCHAPv2 for
712	  authentication (hash:<16-octet hex value>); added nt_password_hash
713	  tool for hashing password to generate NtPasswordHash
714
7152005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
716	* driver_wired: fixed EAPOL sending to optionally use PAE group address
717	  as the destination instead of supplicant MAC address; this is
718	  disabled by default, but should be enabled with use_pae_group_addr=1
719	  in configuration file if the wired interface is used by only one
720	  device at the time (common switch configuration)
721	* driver_madwifi: configure driver to use TKIP countermeasures in order
722	  to get correct behavior (IEEE 802.11 association failing; previously,
723	  association succeeded, but hostpad forced disassociation immediately)
724	* driver_madwifi: added support for madwifi-ng
725
7262005-10-27 - v0.4.6
727	* added support for replacing user identity from EAP with RADIUS
728	  User-Name attribute from Access-Accept message, if that is included,
729	  for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
730	  tunneled identity into accounting messages when the RADIUS server
731	  does not support better way of doing this with Class attribute)
732	* driver_madwifi: fixed EAPOL packet receive for configuration where
733	  ath# is part of a bridge interface
734	* added a configuration file and log analyzer script for logwatch
735	* fixed EAPOL state machine step function to process all state
736	  transitions before processing new events; this resolves a race
737	  condition in which EAPOL-Start message could trigger hostapd to send
738	  two EAP-Response/Identity frames to the authentication server
739
7402005-09-25 - v0.4.5
741	* added client CA list to the TLS certificate request in order to make
742	  it easier for the client to select which certificate to use
743	* added experimental support for EAP-PSK
744	* added support for WE-19 (hostap, madwifi)
745
7462005-08-21 - v0.4.4
747	* fixed build without CONFIG_RSN_PREAUTH
748	* fixed FreeBSD build
749
7502005-06-26 - v0.4.3
751	* fixed PMKSA caching to copy User-Name and Class attributes so that
752	  RADIUS accounting gets correct information
753	* start RADIUS accounting only after successful completion of WPA
754	  4-Way Handshake if WPA-PSK is used
755	* fixed PMKSA caching for the case where STA (re)associates without
756	  first disassociating
757
7582005-06-12 - v0.4.2
759	* EAP-PAX is now registered as EAP type 46
760	* fixed EAP-PAX MAC calculation
761	* fixed EAP-PAX CK and ICK key derivation
762	* renamed eap_authenticator configuration variable to eap_server to
763	  better match with RFC 3748 (EAP) terminology
764	* driver_test: added support for testing hostapd with wpa_supplicant
765	  by using test driver interface without any kernel drivers or network
766	  cards
767
7682005-05-22 - v0.4.1
769	* fixed RADIUS server initialization when only auth or acct server
770	  is configured and the other one is left empty
771	* driver_madwifi: added support for RADIUS accounting
772	* driver_madwifi: added preliminary support for compiling against 'BSD'
773	  branch of madwifi CVS tree
774	* driver_madwifi: fixed pairwise key removal to allow WPA reauth
775	  without disassociation
776	* added support for reading additional certificates from PKCS#12 files
777	  and adding them to the certificate chain
778	* fixed RADIUS Class attribute processing to only use Access-Accept
779	  packets to update Class; previously, other RADIUS authentication
780	  packets could have cleared Class attribute
781	* added support for more than one Class attribute in RADIUS packets
782	* added support for verifying certificate revocation list (CRL) when
783	  using integrated EAP authenticator for EAP-TLS; new hostapd.conf
784	  options 'check_crl'; CRL must be included in the ca_cert file for now
785
7862005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
787	* added support for including network information into
788	  EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
789	  (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
790	* fixed a bug which caused some RSN pre-authentication cases to use
791	  freed memory and potentially crash hostapd
792	* fixed private key loading for cases where passphrase is not set
793	* added support for sending TLS alerts and aborting authentication
794	  when receiving a TLS alert
795	* fixed WPA2 to add PMKSA cache entry when using integrated EAP
796	  authenticator
797	* fixed PMKSA caching (EAP authentication was not skipped correctly
798	  with the new state machine changes from IEEE 802.1X draft)
799	* added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
800	  and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
801	  to be added to .config to include IPv6 support); for RADIUS server,
802	  radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
803	  in RADIUS clients file can then use IPv6 format
804	* added experimental support for EAP-PAX
805	* replaced hostapd control interface library (hostapd_ctrl.[ch]) with
806	  the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
807
8082005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
809
8102005-01-23 - v0.3.5
811	* added support for configuring a forced PEAP version based on the
812	  Phase 1 identity
813	* fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
814	  to terminate authentication
815	* fixed EAP identifier duplicate processing with the new IEEE 802.1X
816	  draft
817	* clear accounting data in the driver when starting a new accounting
818	  session
819	* driver_madwifi: filter wireless events based on ifindex to allow more
820	  than one network interface to be used
821	* fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
822	  setting if the packet does not pass MIC verification (e.g., due to
823	  incorrect PSK); previously, message 1/4 was not tried again if an
824	  invalid message 2/4 was received
825	* fixed reconfiguration of RADIUS client retransmission timer when
826	  adding a new message to the pending list; previously, timer was not
827	  updated at this point and if there was a pending message with long
828	  time for the next retry, the new message needed to wait that long for
829	  its first retry, too
830
8312005-01-09 - v0.3.4
832	* added support for configuring multiple allowed EAP types for Phase 2
833	  authentication (EAP-PEAP, EAP-TTLS)
834	* fixed EAPOL-Start processing to trigger WPA reauthentication
835	  (previously, only EAPOL authentication was done)
836
8372005-01-02 - v0.3.3
838	* added support for EAP-PEAP in the integrated EAP authenticator
839	* added support for EAP-GTC in the integrated EAP authenticator
840	* added support for configuring list of EAP methods for Phase 1 so that
841	  the integrated EAP authenticator can, e.g., use the wildcard entry
842	  for EAP-TLS and EAP-PEAP
843	* added support for EAP-TTLS in the integrated EAP authenticator
844	* added support for EAP-SIM in the integrated EAP authenticator
845	* added support for using hostapd as a RADIUS authentication server
846	  with the integrated EAP authenticator taking care of EAP
847	  authentication (new hostapd.conf options: radius_server_clients and
848	  radius_server_auth_port); this is not included in default build; use
849	  CONFIG_RADIUS_SERVER=y in .config to include
850
8512004-12-19 - v0.3.2
852	* removed 'daemonize' configuration file option since it has not really
853	  been used at all for more than year
854	* driver_madwifi: fixed group key setup and added get_ssid method
855	* added support for EAP-MSCHAPv2 in the integrated EAP authenticator
856
8572004-12-12 - v0.3.1
858	* added support for integrated EAP-TLS authentication (new hostapd.conf
859	  variables: ca_cert, server_cert, private_key, private_key_passwd);
860	  this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
861	  external RADIUS server
862	* added support for reading PKCS#12 (PFX) files (as a replacement for
863	  PEM/DER) to get certificate and private key (CONFIG_PKCS12)
864
8652004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
866	* added support for Acct-{Input,Output}-Gigawords
867	* added support for Event-Timestamp (in RADIUS Accounting-Requests)
868	* added support for RADIUS Authentication Client MIB (RFC2618)
869	* added support for RADIUS Accounting Client MIB (RFC2620)
870	* made EAP re-authentication period configurable (eap_reauth_period)
871	* fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
872	* fixed EAPOL state machine to stop if STA is removed during
873	  eapol_sm_step(); this fixes at least one segfault triggering bug with
874	  IEEE 802.11i pre-authentication
875	* added support for multiple WPA pre-shared keys (e.g., one for each
876	  client MAC address or keys shared by a group of clients);
877	  new hostapd.conf field wpa_psk_file for setting path to a text file
878	  containing PSKs, see hostapd.wpa_psk for an example
879	* added support for multiple driver interfaces to allow hostapd to be
880	  used with other drivers
881	* added wired authenticator driver interface (driver=wired in
882	  hostapd.conf, see wired.conf for example configuration)
883	* added madwifi driver interface (driver=madwifi in hostapd.conf, see
884	  madwifi.conf for example configuration; Note: include files from
885	  madwifi project is needed for building and a configuration file,
886	  .config, needs to be created in hostapd directory with
887	  CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
888	  build)
889	* fixed an alignment issue that could cause SHA-1 to fail on some
890	  platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
891	  align variables)
892	* fixed RADIUS reconnection after an error in sending interim
893	  accounting packets
894	* added hostapd control interface for external programs and an example
895	  CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
896	* started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
897	  'hostapd_cli sta <addr>')
898	* finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
899	* added support for strict GTK rekeying (wpa_strict_rekey in
900	  hostapd.conf)
901	* updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
902	  (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
903	  IEEE 802.11F-2003)
904	* added Prism54 driver interface (driver=prism54 in hostapd.conf;
905	  note: .config needs to be created in hostapd directory with
906	  CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
907	  build)
908	* dual-licensed hostapd (GPLv2 and BSD licenses)
909	* fixed RADIUS accounting to generate a new session id for cases where
910	  a station reassociates without first being complete deauthenticated
911	* fixed STA disassociation handler to mark next timeout state to
912	  deauthenticate the station, i.e., skip long wait for inactivity poll
913	  and extra disassociation, if the STA disassociates without
914	  deauthenticating
915	* added integrated EAP authenticator that can be used instead of
916	  external RADIUS authentication server; currently, only EAP-MD5 is
917	  supported, so this cannot yet be used for key distribution; the EAP
918	  method interface is generic, though, so adding new EAP methods should
919	  be straightforward; new hostapd.conf variables: 'eap_authenticator'
920	  and 'eap_user_file'; this obsoletes "minimal authentication server"
921	  ('minimal_eap' in hostapd.conf) which is now removed
922	* added support for FreeBSD and driver interface for the BSD net80211
923	  layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
924	  .config); please note that some of the required kernel mods have not
925	  yet been committed
926
9272004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
928	* fixed some accounting cases where Accounting-Start was sent when
929	  IEEE 802.1X port was being deauthorized
930
9312004-06-20 - v0.2.3
932	* modified RADIUS client to re-connect the socket in case of certain
933	  error codes that are generated when a network interface state is
934	  changes (e.g., when IP address changes or the interface is set UP)
935	* fixed couple of cases where EAPOL state for a station was freed
936	  twice causing a segfault for hostapd
937	* fixed couple of bugs in processing WPA deauthentication (freed data
938	  was used)
939
9402004-05-31 - v0.2.2
941	* fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
942	* fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
943	  cases where STAs dropped multicast frames as replay attacks
944	* added support for copying RADIUS Attribute 'Class' from
945	  authentication messages into accounting messages
946	* send canned EAP failure if RADIUS server sends Access-Reject without
947	  EAP message (previously, Supplicant was not notified in this case)
948	* fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
949	  not start EAPOL state machines if the STA selected to use WPA-PSK)
950
9512004-05-06 - v0.2.1
952	* added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
953	  - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
954	    (i.e., IEEE 802.11i/D3.0)
955	  - supports WPA-only, RSN-only, and mixed WPA/RSN mode
956	  - both WPA-PSK and WPA-RADIUS/EAP are supported
957	  - PMKSA caching and pre-authentication
958	  - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
959	    wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
960	    rsn_preauth, rsn_preauth_interfaces
961	* fixed interim accounting to remove any pending accounting messages
962	  to the STA before sending a new one
963
9642004-02-15 - v0.2.0
965	* added support for Acct-Interim-Interval:
966	  - draft-ietf-radius-acct-interim-01.txt
967	  - use Acct-Interim-Interval attribute from Access-Accept if local
968	    'radius_acct_interim_interval' is not set
969	  - allow different update intervals for each STA
970	* fixed event loop to call signal handlers only after returning from
971	  the real signal handler
972	* reset sta->timeout_next after successful association to make sure
973	  that the previously registered inactivity timer will not remove the
974	  STA immediately (e.g., if STA deauthenticates and re-associates
975	  before the timer is triggered).
976	* added new hostapd.conf variable, nas_identifier, that can be used to
977	  add an optional RADIUS Attribute, NAS-Identifier, into authentication
978	  and accounting messages
979	* added support for Accounting-On and Accounting-Off messages
980	* fixed accounting session handling to send Accounting-Start only once
981	  per session and not to send Accounting-Stop if the session was not
982	  initialized properly
983	* fixed Accounting-Stop statistics in cases where the message was
984	  previously sent after the kernel entry for the STA (and/or IEEE
985	  802.1X data) was removed
986
987
