11	  configurable
12	* improved P2P operating channel selection for various multi-channel
13	  concurrency cases

58	* fixed TDLS AID configuration for VHT
59	* modified -m<conf> configuration file to be used only for the P2P

508	  (p2p_no_group_iface=1)
509	* fixed P2P Bonjour SD to match entries with both compressed and not
510	  compressed domain name format and support multiple Bonjour PTR matches
511	  for the same key
512	* use deauthentication instead of disassociation for all disconnection
513	  operations; this removes the now unused disassociate() wpa_driver_ops
514	  callback
515	* optimized PSK generation on P2P GO by caching results to avoid
516	  multiple PBKDF2 operations
517	* added okc=1 global configuration parameter to allow OKC to be enabled
518	  by default for all network blocks
519	* added a workaround for WPS PBC session overlap detection to avoid
520	  interop issues with deployed station implementations that do not
521	  remove active PBC indication from Probe Request frames properly
522	* added basic support for 60 GHz band
523	* extend EAPOL frames processing workaround for roaming cases
524	  (postpone processing of unexpected EAPOL frame until association
525	  event to handle reordered events)
526
5272012-05-10 - v1.0
528	* bsd: Add support for setting HT values in IFM_MMASK.
529	* Delay STA entry removal until Deauth/Disassoc TX status in AP mode.
530	  This allows the driver to use PS buffering of Deauthentication and
531	  Disassociation frames when the STA is in power save sleep. Only
532	  available with drivers that provide TX status events for Deauth/
533	  Disassoc frames (nl80211).
534	* Drop oldest unknown BSS table entries first. This makes it less
535	  likely to hit connection issues in environments with huge number
536	  of visible APs.
537	* Add systemd support.
538	* Add support for setting the syslog facility from the config file
539	  at build time.
540	* atheros: Add support for IEEE 802.11w configuration.
541	* AP mode: Allow enable HT20 if driver supports it, by setting the
542	  config parameter ieee80211n.
543	* Allow AP mode to disconnect STAs based on low ACK condition (when
544	  the data connection is not working properly, e.g., due to the STA
545	  going outside the range of the AP). Disabled by default, enable by
546	  config option disassoc_low_ack.
547	* nl80211:
548	  - Support GTK rekey offload.
549	  - Support PMKSA candidate events. This adds support for RSN

553	  - Add a DBus signal for EAP SM requests, emitted on the Interface
554	    object.
555	  - Export max scan ssids supported by the driver as MaxScanSSID.
556	  - Add signal Certification for information about server certification.
557	  - Add BSSExpireAge and BSSExpireCount interface properties and
558	    support set/get, which allows for setting BSS cache expiration age
559	    and expiration scan count.
560	  - Add ConfigFile to AddInterface properties.
561	  - Add Interface.Country property and support to get/set the value.
562	  - Add DBus property CurrentAuthMode.
563	  - P2P DBus API added.
564	  - Emit property changed events (for property BSSs) when adding/
565	    removing BSSs.
566	  - Treat '' in SSIDs of Interface.Scan as a request for broadcast
567	    scan, instead of ignoring it.
568	  - Add DBus getter/setter for FastReauth.
569	  - Raise PropertiesChanged on org.freedesktop.DBus.Properties.
570	* wpa_cli:
571	  - Send AP-STA-DISCONNECTED event when an AP disconnects a station
572	    due to inactivity.
573	  - Make second argument to set command optional. This can be used to
574	    indicate a zero length value.
575	  - Add signal_poll command.
576	  - Add bss_expire_age and bss_expire_count commands to set/get BSS
577	    cache expiration age and expiration scan count.
578	  - Add ability to set scan interval (the time in seconds wpa_s waits
579	    before requesting a new scan after failing to find a suitable
580	    network in scan results) using scan_interval command.
581	  - Add event CTRL-EVENT-ASSOC-REJECT for association rejected.
582	  - Add command get version, that returns wpa_supplicant version string.
583	  - Add command sta_autoconnect for disabling automatic reconnection
584	    on receiving disconnection event.
585	  - Setting bssid parameter to an empty string "" or any can now be
586	    used to clear the bssid_set flag in a network block, i.e., to remove
587	    bssid filtering.
588	  - Add tdls_testing command to add a special testing feature for
589	    changing TDLS behavior. Build param CONFIG_TDLS_TESTING must be
590	    enabled as well.
591	  - For interworking, add wpa_cli commands interworking_select,
592	    interworking_connect, anqp_get, fetch_anqp, and stop_fetch_anqp.
593	  - Many P2P commands were added. See README-P2P.
594	  - Many WPS/WPS ER commands - see WPS/WPS ER sections for details.
595	  - Allow set command to change global config parameters.
596	  - Add log_level command, which can be used to display the current
597	    debugging level and to change the log level during run time.
598	  - Add note command, which can be used to insert notes to the debug
599	    log.
600	  - Add internal line edit implementation. CONFIG_WPA_CLI_EDIT=y
601	    can now be used to build wpa_cli with internal implementation of
602	    line editing and history support. This can be used as a replacement
603	    for CONFIG_READLINE=y.
604	* AP mode: Add max_num_sta config option, which can be used to limit
605	  the number of stations allowed to connect to the AP.
606	* Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad
607	  config file.
608	* wext: Increase scan timeout from 5 to 10 seconds.
609	* Add blacklist command, allowing an external program to
610	  manage the BSS blacklist and display its current contents.
611	* WPS:
612	  - Add wpa_cli wps_pin get command for generating random PINs. This can
613	    be used in a UI to generate a PIN without starting WPS (or P2P)
614	    operation.
615	  - Set RF bands based on driver capabilities, instead of hardcoding
616	    them.
617	  - Add mechanism for indicating non-standard WPS errors.

619	    by default.
620	  - Add wps_ap_pin cli command for wpa_supplicant AP mode.
621	  - Add wps_check_pin cli command for processing PIN from user input.
622	    UIs can use this command to process a PIN entered by a user and to
623	    validate the checksum digit (if present).
624	  - Cancel WPS operation on PBC session overlap detection.
625	  - New wps_cancel command in wpa_cli will cancel a pending WPS
626	    operation.
627	  - wpa_cli action: Add WPS_EVENT_SUCCESS and WPS_EVENT_FAIL handlers.
628	  - Trigger WPS config update on Manufacturer, Model Name, Model
629	    Number, and Serial Number changes.
630	  - Fragment size is now configurable for EAP-WSC peer. Use
631	    wpa_cli set wps_fragment_size <val>.
632	  - Disable AP PIN after 10 consecutive failures. Slow down attacks on
633	    failures up to 10.
634	  - Allow AP to start in Enrollee mode without AP PIN for probing, to
635	    be compatible with Windows 7.
636	  - Add Config Error into WPS-FAIL events to provide more info to the
637	    user on how to resolve the issue.
638	  - Label and Display config methods are not allowed to be enabled
639	    at the same time, since it is unclear which PIN to use if both
640	    methods are advertised.
641	  - When controlling multiple interfaces:
642	     - apply WPS commands to all interfaces configured to use WPS
643	     - apply WPS config changes to all interfaces that use WPS
644	     - when an attack is detected on any interface, disable AP PIN on
645	       all interfaces
646	* WPS ER:
647	  - Add special AP Setup Locked mode to allow read only ER.
648	    ap_setup_locked=2 can now be used to enable a special mode where
649	    WPS ER can learn the current AP settings, but cannot change them.
650	  - Show SetSelectedRegistrar events as ctrl_iface events
651	  - Add wps_er_set_config to enroll a network based on a local
652	    network configuration block instead of having to (re-)learn the
653	    current AP settings with wps_er_learn.
654	  - Allow AP filtering based on IP address, add ctrl_iface event for
655	    learned AP settings, add wps_er_config command to configure an AP.
656	* WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2)
657	  - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool
658	    for testing protocol extensibility.
659	  - Add build option CONFIG_WPS_STRICT to allow disabling of WPS
660	    workarounds.
661	  - Add support for AuthorizedMACs attribute.
662	* TDLS:
663	  - Propogate TDLS related nl80211 capability flags from kernel and
664	    add them as driver capability flags. If the driver doesn't support
665	    capabilities, assume TDLS is supported internally. When TDLS is
666	    explicitly not supported, disable all user facing TDLS operations.
667	  - Allow TDLS to be disabled at runtime (mostly for testing).
668	    Use set tdls_disabled.
669	  - Honor AP TDLS settings that prohibit/allow TDLS.
670	  - Add a special testing feature for changing TDLS behavior. Use
671	    CONFIG_TDLS_TESTING build param to enable. Configure at runtime
672	    with tdls_testing cli command.
673	  - Add support for TDLS 802.11z.
674	* wlantest: Add a tool wlantest for IEEE802.11 protocol testing.
675	  wlantest can be used to capture frames from a monitor interface
676	  for realtime capturing or from pcap files for offline analysis.
677	* Interworking: Support added for 802.11u. Enable in .config with
678	  CONFIG_INTERWORKING. See wpa_supplicant.conf for config parameters
679	  for interworking. wpa_cli commands added to support this are
680	  interworking_select, interworking_connect, anqp_get, fetch_anqp,
681	  and stop_fetch_anqp.
682	* Android: Add build and runtime support for Android wpa_supplicant.
683	* bgscan learn: Add new bgscan that learns BSS information based on
684	  previous scans, and uses that information to dynamically generate
685	  the list of channels for background scans.
686	* Add a new debug message level for excessive information. Use
687	  -ddd to enable.
688	* TLS: Add support for tls_disable_time_checks=1 in client mode.
689	* Internal TLS:
690	  - Add support for TLS v1.1 (RFC 4346). Enable with build parameter
691	    CONFIG_TLSV11.
692	  - Add domainComponent parser for X.509 names.
693	* Linux: Add RFKill support by adding an interface state "disabled".
694	* Reorder some IEs to get closer to IEEE 802.11 standard. Move
695	  WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames.
696	  Move HT IEs to be later in (Re)Assoc Resp.
697	* Solaris: Add support for wired 802.1X client.
698	* Wi-Fi Direct support. See README-P2P for more information.
699	* Many bugfixes.
700
7012010-04-18 - v0.7.2
702	* nl80211: fixed number of issues with roaming
703	* avoid unnecessary roaming if multiple APs with similar signal
704	  strength are present in scan results
705	* add TLS client events and server probing to ease design of
706	  automatic detection of EAP parameters
707	* add option for server certificate matching (SHA256 hash of the
708	  certificate) instead of trusted CA certificate configuration
709	* bsd: Cleaned up driver wrapper and added various low-level
710	  configuration options
711	* wpa_gui-qt4: do not show too frequent WPS AP available events as
712	  tray messages
713	* TNC: fixed issues with fragmentation
714	* EAP-TNC: add Flags field into fragment acknowledgement (needed to
715	  interoperate with other implementations; may potentially breaks
716	  compatibility with older wpa_supplicant/hostapd versions)
717	* wpa_cli: added option for using a separate process to receive event
718	  messages to reduce latency in showing these
719	  (CFLAGS += -DCONFIG_WPA_CLI_FORK=y in .config to enable this)
720	* maximum BSS table size can now be configured (bss_max_count)
721	* BSSes to be included in the BSS table can be filtered based on
722	  configured SSIDs to save memory (filter_ssids)
723	* fix number of issues with IEEE 802.11r/FT; this version is not
724	  backwards compatible with old versions
725	* nl80211: add support for IEEE 802.11r/FT protocol (both over-the-air
726	  and over-the-DS)
727	* add freq_list network configuration parameter to allow the AP
728	  selection to filter out entries based on the operating channel
729	* add signal strength change events for bgscan; this allows more
730	  dynamic changes to background scanning interval based on changes in
731	  the signal strength with the current AP; this improves roaming within
732	  ESS quite a bit, e.g., with bgscan="simple:30:-45:300" in the network
733	  configuration block to request background scans less frequently when
734	  signal strength remains good and to automatically trigger background
735	  scans whenever signal strength drops noticeably
736	  (this is currently only available with nl80211)
737	* add BSSID and reason code (if available) to disconnect event messages
738	* wpa_gui-qt4: more complete support for translating the GUI with
739	  linguist and add German translation
740	* fix DH padding with internal crypto code (mainly, for WPS)
741	* do not trigger initial scan automatically anymore if there are no
742	  enabled networks
743
7442010-01-16 - v0.7.1
745	* cleaned up driver wrapper API (struct wpa_driver_ops); the new API
746	  is not fully backwards compatible, so out-of-tree driver wrappers
747	  will need modifications
748	* cleaned up various module interfaces
749	* merge hostapd and wpa_supplicant developers' documentation into a
750	  single document
751	* nl80211: use explicit deauthentication to clear cfg80211 state to
752	  avoid issues when roaming between APs
753	* dbus: major design changes in the new D-Bus API
754	  (fi.w1.wpa_supplicant1)
755	* nl80211: added support for IBSS networks
756	* added internal debugging mechanism with backtrace support and memory
757	  allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y)
758	* added WPS ER unsubscription command to more cleanly unregister from
759	  receiving UPnP events when ER is terminated
760	* cleaned up AP mode operations to avoid need for virtual driver_ops
761	  wrapper
762	* added BSS table to maintain more complete scan result information
763	  over multiple scans (that may include only partial results)
764	* wpa_gui-qt4: update Peers dialog information more dynamically while
765	  the dialog is kept open
766	* fixed PKCS#12 use with OpenSSL 1.0.0
767	* driver_wext: Added cfg80211-specific optimization to avoid some
768	  unnecessary scans and to speed up association
769
7702009-11-21 - v0.7.0
771	* increased wpa_cli ping interval to 5 seconds and made this
772	  configurable with a new command line options (-G<seconds>)
773	* fixed scan buffer processing with WEXT to handle up to 65535
774	  byte result buffer (previously, limited to 32768 bytes)
775	* allow multiple driver wrappers to be specified on command line
776	  (e.g., -Dnl80211,wext); the first one that is able to initialize the
777	  interface will be used
778	* added support for multiple SSIDs per scan request to optimize
779	  scan_ssid=1 operations in ap_scan=1 mode (i.e., search for hidden
780	  SSIDs); this requires driver support and can currently be used only
781	  with nl80211
782	* added support for WPS USBA out-of-band mechanism with USB Flash
783	  Drives (UFD) (CONFIG_WPS_UFD=y)
784	* driver_ndis: add PAE group address to the multicast address list to
785	  fix wired IEEE 802.1X authentication
786	* fixed IEEE 802.11r key derivation function to match with the standard
787	  (note: this breaks interoperability with previous version) [Bug 303]
788	* added better support for drivers that allow separate authentication
789	  and association commands (e.g., mac80211-based Linux drivers with
790	  nl80211; SME in wpa_supplicant); this allows over-the-air FT protocol
791	  to be used (IEEE 802.11r)
792	* fixed SHA-256 based key derivation function to match with the
793	  standard when using CCMP (for IEEE 802.11r and IEEE 802.11w)
794	  (note: this breaks interoperability with previous version) [Bug 307]
795	* use shared driver wrapper files with hostapd
796	* added AP mode functionality (CONFIG_AP=y) with mode=2 in the network
797	  block; this can be used for open and WPA2-Personal networks
798	  (optionally, with WPS); this links in parts of hostapd functionality
799	  into wpa_supplicant
800	* wpa_gui-qt4: added new Peers dialog to show information about peers
801	  (other devices, including APs and stations, etc. in the neighborhood)
802	* added support for WPS External Registrar functionality (configure APs
803	  and enroll new devices); can be used with wpa_gui-qt4 Peers dialog
804	  and wpa_cli commands wps_er_start, wps_er_stop, wps_er_pin,
805	  wps_er_pbc, wps_er_learn
806	  (this can also be used with a new 'none' driver wrapper if no
807	  wireless device or IEEE 802.1X on wired is needed)
808	* driver_nl80211: multiple updates to provide support for new Linux
809	  nl80211/mac80211 functionality
810	* updated management frame protection to use IEEE Std 802.11w-2009
811	* fixed number of small WPS issues and added workarounds to
812	  interoperate with common deployed broken implementations
813	* added support for NFC out-of-band mechanism with WPS
814	* driver_ndis: fixed wired IEEE 802.1X authentication with PAE group
815	  address frames
816	* added preliminary support for IEEE 802.11r RIC processing
817	* added support for specifying subset of enabled frequencies to scan
818	  (scan_freq option in the network configuration block); this can speed
819	  up scanning process considerably if it is known that only a small
820	  subset of channels is actually used in the network (this is currently
821	  supported only with -Dnl80211)
822	* added a workaround for race condition between receiving the
823	  association event and the following EAPOL-Key
824	* added background scan and roaming infrastructure to allow
825	  network-specific optimizations to be used to improve roaming within
826	  an ESS (same SSID)
827	* added new DBus interface (fi.w1.wpa_supplicant1)
828
8292009-01-06 - v0.6.7
830	* added support for Wi-Fi Protected Setup (WPS)
831	  (wpa_supplicant can now be configured to act as a WPS Enrollee to
832	  enroll credentials for a network using PIN and PBC methods; in
833	  addition, wpa_supplicant can act as a wireless WPS Registrar to
834	  configure an AP); WPS support can be enabled by adding CONFIG_WPS=y
835	  into .config and setting the runtime configuration variables in
836	  wpa_supplicant.conf (see WPS section in the example configuration
837	  file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to
838	  manage WPS negotiation; see README-WPS for more details
839	* added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
840	* added support for using driver_test over UDP socket
841	* fixed PEAPv0 Cryptobinding interoperability issue with Windows Server
842	  2008 NPS; optional cryptobinding is now enabled (again) by default
843	* fixed PSK editing in wpa_gui
844	* changed EAP-GPSK to use the IANA assigned EAP method type 51
845	* added a Windows installer that includes WinPcap and all the needed
846	  DLLs; in addition, it set up the registry automatically so that user
847	  will only need start wpa_gui to get prompted to start the wpasvc
848	  servide and add a new interface if needed through wpa_gui dialog
849	* updated management frame protection to use IEEE 802.11w/D7.0
850
8512008-11-23 - v0.6.6
852	* added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
853	  (can be used to simulate test SIM/USIM card with a known private key;
854	  enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
855	  and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
856	* added a new network configuration option, wpa_ptk_rekey, that can be
857	  used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
858	  against TKIP deficiencies
859	* added an optional mitigation mechanism for certain attacks against
860	  TKIP by delaying Michael MIC error reports by a random amount of time
861	  between 0 and 60 seconds; this can be enabled with a build option
862	  CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
863	* fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
864	  not bytes
865	* updated OpenSSL code for EAP-FAST to use an updated version of the
866	  session ticket overriding API that was included into the upstream
867	  OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
868	  needed with that version anymore)
869	* updated userspace MLME instructions to match with the current Linux
870	  mac80211 implementation; please also note that this can only be used
871	  with driver_nl80211.c (the old code from driver_wext.c was removed)
872	* added support (Linux only) for RoboSwitch chipsets (often found in
873	  consumer grade routers); driver interface 'roboswitch'
874	* fixed canceling of PMKSA caching when using drivers that generate
875	  RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
876	  about
877
8782008-11-01 - v0.6.5
879	* added support for SHA-256 as X.509 certificate digest when using the
880	  internal X.509/TLSv1 implementation
881	* updated management frame protection to use IEEE 802.11w/D6.0
882	* added support for using SHA256-based stronger key derivation for WPA2
883	  (IEEE 802.11w)
884	* fixed FT (IEEE 802.11r) authentication after a failed association to
885	  use correct FTIE
886	* added support for configuring Phase 2 (inner/tunneled) authentication
887	  method with wpa_gui-qt4
888
8892008-08-10 - v0.6.4
890	* added support for EAP Sequences in EAP-FAST Phase 2
891	* added support for using TNC with EAP-FAST
892	* added driver_ps3 for the PS3 Linux wireless driver
893	* added support for optional cryptobinding with PEAPv0
894	* fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
895	  allow fallback to full handshake if server rejects PAC-Opaque
896	* added fragmentation support for EAP-TNC
897	* added support for parsing PKCS #8 formatted private keys into the
898	  internal TLS implementation (both PKCS #1 RSA key and PKCS #8
899	  encapsulated RSA key can now be used)
900	* added option of using faster, but larger, routines in the internal
901	  LibTomMath (for internal TLS implementation) to speed up DH and RSA
902	  calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
903	* fixed race condition between disassociation event and group key
904	  handshake to avoid getting stuck in incorrect state [Bug 261]
905	* fixed opportunistic key caching (proactive_key_caching)
906
9072008-02-22 - v0.6.3
908	* removed 'nai' and 'eappsk' network configuration variables that were
909	  previously used for configuring user identity and key for EAP-PSK,
910	  EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
911	  replacement for 'nai' (if old configuration used a separate
912	  'identity' value, that would now be configured as
913	  'anonymous_identity'). 'password' field is now used as the
914	  replacement for 'eappsk' (it can also be set using hexstring to
915	  present random binary data)
916	* removed '-w' command line parameter (wait for interface to be added,
917	  if needed); cleaner way of handling this functionality is to use an
918	  external mechanism (e.g., hotplug scripts) that start wpa_supplicant
919	  when an interface is added
920	* updated FT support to use the latest draft, IEEE 802.11r/D9.0
921	* added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
922	  indicating when new scan results become available
923	* added new ctrl_iface command, BSS, to allow scan results to be
924	  fetched without hitting the message size limits (this command
925	  can be used to iterate through the scan results one BSS at the time)
926	* fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
927	  attributes in EAP-SIM Start/Response when using fast reauthentication
928	* fixed EAPOL not to end up in infinite loop when processing dynamic
929	  WEP keys with IEEE 802.1X
930	* fixed problems in getting NDIS events from WMI on Windows 2000
931
9322008-01-01 - v0.6.2
933	* added support for Makefile builds to include debug-log-to-a-file
934	  functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
935	* fixed EAP-SIM and EAP-AKA message parser to validate attribute
936	  lengths properly to avoid potential crash caused by invalid messages
937	* added data structure for storing allocated buffers (struct wpabuf);
938	  this does not affect wpa_supplicant usage, but many of the APIs
939	  changed and various interfaces (e.g., EAP) is not compatible with old
940	  versions
941	* added support for protecting EAP-AKA/Identity messages with
942	  AT_CHECKCODE (optional feature in RFC 4187)
943	* added support for protected result indication with AT_RESULT_IND for
944	  EAP-SIM and EAP-AKA (phase1="result_ind=1")
945	* added driver_wext workaround for race condition between scanning and
946	  association with drivers that take very long time to scan all
947	  channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
948	  using a longer hardcoded timeout for the scan if the driver supports
949	  notifications for scan completion (SIOCGIWSCAN event); this helps,
950	  e.g., in cases where wpa_supplicant and madwifi driver ended up in
951	  loop where the driver did not even try to associate
952	* stop EAPOL timer tick when no timers are in use in order to reduce
953	  power consumption (no need to wake up the process once per second)
954	  [Bug 237]
955	* added support for privilege separation (run only minimal part of
956	  wpa_supplicant functionality as root and rest as unprivileged,
957	  non-root process); see 'Privilege separation' in README for details;
958	  this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
959	  in .config
960	* changed scan results data structure to include all information
961	  elements to make it easier to support new IEs; old get_scan_result()
962	  driver_ops is still supported for backwards compatibility (results
963	  are converted internally to the new format), but all drivers should
964	  start using the new get_scan_results2() to make them more likely to
965	  work with new features
966	* Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
967	  application, i.e., it does not require Qt3Support anymore; Windows
968	  binary of wpa_gui.exe is now from this directory and only requires
969	  QtCore4.dll and QtGui4.dll libraries
970	* updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
971	  available as a separate package to make wpa_gui installation easier:
972	  http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
973	* added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
974	  only shared key/password authentication is supported in this version
975
9762007-11-24 - v0.6.1
977	* added support for configuring password as NtPasswordHash
978	  (16-byte MD4 hash of password) in hash:<32 hex digits> format
979	* added support for fallback from abbreviated TLS handshake to
980	  full handshake when using EAP-FAST (e.g., due to an expired
981	  PAC-Opaque)
982	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
983	  draft (draft-ietf-emu-eap-gpsk-07.txt)
984	* added support for drivers that take care of RSN 4-way handshake
985	  internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
986	  WPA_ALG_PMK in set_key)
987	* added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
988	  .config); this version supports only ap_scan=2 mode and allow the
989	  driver to take care of the 4-way handshake
990	* fixed a buffer overflow in parsing TSF from scan results when using
991	  driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
992	  [Bug 232]
993	* updated FT support to use the latest draft, IEEE 802.11r/D8.0
994	* fixed an integer overflow issue in the ASN.1 parser used by the
995	  (experimental) internal TLS implementation to avoid a potential
996	  buffer read overflow
997	* fixed a race condition with -W option (wait for a control interface
998	  monitor before starting) that could have caused the first messages to
999	  be lost
1000	* added support for processing TNCC-TNCS-Messages to report
1001	  recommendation (allow/none/isolate) when using TNC [Bug 243]
1002
10032007-05-28 - v0.6.0
1004	* added network configuration parameter 'frequency' for setting
1005	  initial channel for IBSS (adhoc) networks
1006	* added experimental IEEE 802.11r/D6.0 support
1007	* updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
1008	* updated EAP-PSK to use the IANA-allocated EAP type 47
1009	* fixed EAP-PAX key derivation
1010	* fixed EAP-PSK bit ordering of the Flags field
1011	* fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
1012	  tunnelled identity request (previously, the identifier from the outer
1013	  method was used, not the tunnelled identifier which could be
1014	  different)
1015	* added support for fragmentation of outer TLS packets during Phase 2
1016	  of EAP-PEAP/TTLS/FAST
1017	* fixed EAP-TTLS AVP parser processing for too short AVP lengths
1018	* added support for EAP-FAST authentication with inner methods that
1019	  generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
1020	  for PAC provisioning)
1021	* added support for authenticated EAP-FAST provisioning
1022	* added support for configuring maximum number of EAP-FAST PACs to
1023	  store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
1024	* added support for storing EAP-FAST PACs in binary format
1025	  (fast_pac_format=binary in phase1 string)
1026	* fixed dbus ctrl_iface to validate message interface before
1027	  dispatching to avoid a possible segfault [Bug 190]
1028	* fixed PeerKey key derivation to use the correct PRF label
1029	* updated Windows binary build to link against OpenSSL 0.9.8d and
1030	  added support for EAP-FAST
1031	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
1032	  draft (draft-ietf-emu-eap-gpsk-04.txt)
1033	* fixed EAP-AKA Notification processing to allow Notification to be
1034	  processed after AKA Challenge response has been sent
1035	* updated to use IEEE 802.11w/D2.0 for management frame protection
1036	  (still experimental)
1037	* fixed EAP-TTLS implementation not to crash on use of freed memory
1038	  if TLS library initialization fails
1039	* added support for EAP-TNC (Trusted Network Connect)
1040	  (this version implements the EAP-TNC method and EAP-TTLS changes
1041	  needed to run two methods in sequence (IF-T) and the IF-IMC and
1042	  IF-TNCCS interfaces from TNCC)
1043
10442006-11-24 - v0.5.6
1045	* added experimental, integrated TLSv1 client implementation with the
1046	  needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
1047	  setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
1048	  .config); this can be useful, e.g., if the target system does not
1049	  have a suitable TLS library and a minimal code size is required
1050	  (total size of this internal TLS/crypto code is bit under 50 kB on
1051	  x86 and the crypto code is shared by rest of the supplicant so some
1052	  of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
1053	* removed STAKey handshake since PeerKey handshake has replaced it in
1054	  IEEE 802.11ma and there are no known deployments of STAKey
1055	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
1056	  draft (draft-ietf-emu-eap-gpsk-01.txt)
1057	* added preliminary implementation of IEEE 802.11w/D1.0 (management
1058	  frame protection)
1059	  (Note: this requires driver support to work properly.)
1060	  (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
1061	* fixed Windows named pipes ctrl_iface to not stop listening for
1062	  commands if client program opens a named pipe and closes it
1063	  immediately without sending a command
1064	* fixed USIM PIN status determination for the case that PIN is not
1065	  needed (this allows EAP-AKA to be used with USIM cards that do not
1066	  use PIN)
1067	* added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
1068	  be used with cards that do not support file selection based on
1069	  partial AID
1070	* added support for matching the subjectAltName of the authentication
1071	  server certificate against multiple name components (e.g.,
1072	  altsubject_match="DNS:server.example.com;DNS:server2.example.com")
1073	* fixed EAP-SIM/AKA key derivation for re-authentication case (only
1074	  affects IEEE 802.1X with dynamic WEP keys)
1075	* changed ctrl_iface network configuration 'get' operations to not
1076	  return password/key material; if these fields are requested, "*"
1077	  will be returned if the password/key is set, but the value of the
1078	  parameter is not exposed
1079
10802006-08-27 - v0.5.5
1081	* added support for building Windows version with UNICODE defined
1082	  (wide-char functions)
1083	* driver_ndis: fixed static WEP configuration to avoid race condition
1084	  issues with some NDIS drivers between association and setting WEP
1085	  keys
1086	* driver_ndis: added validation for IELength value in scan results to
1087	  avoid crashes when using buggy NDIS drivers [Bug 165]
1088	* fixed Release|Win32 target in the Visual Studio project files
1089	  (previously, only Debug|Win32 target was set properly)
1090	* changed control interface API call wpa_ctrl_pending() to allow it to
1091	  return -1 on error (e.g., connection lost); control interface clients
1092	  will need to make sure that they verify that the value is indeed >0
1093	  when determining whether there are pending messages
1094	* added an alternative control interface backend for Windows targets:
1095	  Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
1096	  control interface mechanism for Windows builds (previously, UDP to
1097	  localhost was used)
1098	* changed ctrl_interface configuration for UNIX domain sockets:
1099	  - deprecated ctrl_interface_group variable (it may be removed in
1100	    future versions)
1101	  - allow both directory and group be configured with ctrl_interface
1102	    in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
1103	  - ctrl_interface=/var/run/wpa_supplicant is still supported for the
1104	    case when group is not changed
1105	* added support for controlling more than one interface per process in
1106	  Windows version
1107	* added a workaround for a case where the AP is using unknown address
1108	  (e.g., MAC address of the wired interface) as the source address for
1109	  EAPOL-Key frames; previously, that source address was used as the
1110	  destination for EAPOL-Key frames and in key derivation; now, BSSID is
1111	  used even if the source address does not match with it
1112	  (this resolves an interoperability issue with Thomson SpeedTouch 580)
1113	* added a workaround for UDP-based control interface (which was used in
1114	  Windows builds before this release) to prevent packets with forged
1115	  addresses from being accepted as local control requests
1116	* removed ndis_events.cpp and possibility of using external
1117	  ndis_events.exe; C version (ndis_events.c) is fully functional and
1118	  there is no desire to maintain two separate versions of this
1119	  implementation
1120	* ndis_events: Changed NDIS event notification design to use WMI to
1121	  learn the adapter description through Win32_PnPEntity class; this
1122	  should fix some cases where the adapter name was not recognized
1123	  correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
1124	  USB) [Bug 113]
1125	* fixed selection of the first network in ap_scan=2 mode; previously,
1126	  wpa_supplicant could get stuck in SCANNING state when only the first
1127	  network for enabled (e.g., after 'wpa_cli select_network 0')
1128	* winsvc: added support for configuring ctrl_interface parameters in
1129	  registry (ctrl_interface string value in
1130	  HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
1131	  required to enable control interface (previously, this was hardcoded
1132	  to be enabled)
1133	* allow wpa_gui subdirectory to be built with both Qt3 and Qt4
1134	* converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
1135
11362006-06-20 - v0.5.4
1137	* fixed build with CONFIG_STAKEY=y [Bug 143]
1138	* added support for doing MLME (IEEE 802.11 management frame
1139	  processing) in wpa_supplicant when using Devicescape IEEE 802.11
1140	  stack (wireless-dev.git tree)
1141	* added a new network block configuration option, fragment_size, to
1142	  configure the maximum EAP fragment size
1143	* driver_ndis: Disable WZC automatically for the selected interface to
1144	  avoid conflicts with two programs trying to control the radio; WZC
1145	  will be re-enabled (if it was enabled originally) when wpa_supplicant
1146	  is terminated
1147	* added an experimental TLSv1 client implementation
1148	  (CONFIG_TLS=internal) that can be used instead of an external TLS
1149	  library, e.g., to reduce total size requirement on systems that do
1150	  not include any TLS library by default (this is not yet complete;
1151	  basic functionality is there, but certificate validation is not yet
1152	  included)
1153	* added PeerKey handshake implementation for IEEE 802.11e
1154	  direct link setup (DLS) to replace STAKey handshake
1155	* fixed WPA PSK update through ctrl_iface for the case where the old
1156	  PSK was derived from an ASCII passphrase and the new PSK is set as
1157	  a raw PSK (hex string)
1158	* added new configuration option for identifying which network block
1159	  was used (id_str in wpa_supplicant.conf; included on
1160	  WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
1161	  variable in wpa_cli action scripts; in addition WPA_ID variable is
1162	  set to the current unique identifier that wpa_supplicant assigned
1163	  automatically for the network and that can be used with
1164	  GET_NETWORK/SET_NETWORK ctrl_iface commands)
1165	* wpa_cli action script is now called only when the connect/disconnect
1166	  status changes or when associating with a different network
1167	* fixed configuration parser not to remove CCMP from group cipher list
1168	  if WPA-None (adhoc) is used (pairwise=NONE in that case)
1169	* fixed integrated NDIS events processing not to hang the process due
1170	  to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
1171	* added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
1172	  draft-clancy-emu-eap-shared-secret-00.txt)
1173	* added Microsoft Visual Studio 2005 solution and project files for
1174	  build wpa_supplicant for Windows (see vs2005 subdirectory)
1175	* eloop_win: fixed unregistration of Windows events
1176	* l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
1177	  at the end of RSN pre-authentication and added unregistration of
1178	  a Windows event to avoid getting eloop_win stuck with an invalid
1179	  handle
1180	* driver_ndis: added support for selecting AP based on BSSID
1181	* added new environmental variable for wpa_cli action scripts:
1182	  WPA_CTRL_DIR is the current control interface directory
1183	* driver_ndis: added support for using NDISUIO instead of WinPcap for
1184	  OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
1185	  l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
1186	  wpa_supplicant without requiring WinPcap; note that using NDISUIO
1187	  requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
1188	  only one application to open the device
1189	* changed NDIS driver naming to only include device GUID, e.g.,
1190	  {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
1191	  specific \Device\NPF_ prefix before the GUID; the prefix is still
1192	  allowed for backwards compatibility, but it is not required anymore
1193	  when specifying the interface
1194	* driver_ndis: re-initialize driver interface is the adapter is removed
1195	  and re-inserted [Bug 159]
1196	* driver_madwifi: fixed TKIP and CCMP sequence number configuration on
1197	  big endian hosts [Bug 146]
1198
11992006-04-27 - v0.5.3
1200	* fixed EAP-GTC response to include correct user identity when run as
1201	  phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
1202	* driver_ndis: Fixed encryption mode configuration for unencrypted
1203	  networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
1204	  refused to associate with open networks) [Bug 106]
1205	* driver_ndis: use BSSID OID polling to detect when IBSS network is
1206	  formed even when ndis_events code is included since some NDIS drivers
1207	  do not generate media connect events in IBSS mode
1208	* config_winreg: allow global ctrl_interface parameter to be configured
1209	  in Windows registry
1210	* config_winreg: added support for saving configuration data into
1211	  Windows registry
1212	* added support for controlling network device operational state
1213	  (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
1214	  http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
1215	  that can use this information)
1216	* driver_wext: added support for WE-21 change to SSID configuration
1217	* driver_wext: fixed privacy configuration for static WEP keys mode
1218	  [Bug 140]
1219	* added an optional driver_ops callback for MLME-SETPROTECTION.request
1220	  primitive
1221	* added support for EAP-SAKE (no EAP method number allocated yet, so
1222	  this is using the same experimental type 255 as EAP-PSK)
1223	* added support for dynamically loading EAP methods (.so files) instead
1224	  of requiring them to be statically linked in; this is disabled by
1225	  default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
1226	  on how to use this)
1227
12282006-03-19 - v0.5.2
1229	* do not try to use USIM APDUs when initializing PC/SC for SIM card
1230	  access for a network that has not enabled EAP-AKA
1231	* fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
1232	  v0.5.1 due to the new support for expanded EAP types)
1233	* added support for generating EAP Expanded Nak
1234	* try to fetch scan results once before requesting new scan when
1235	  starting up in ap_scan=1 mode (this can speed up initial association
1236	  a lot with, e.g., madwifi-ng driver)
1237	* added support for receiving EAPOL frames from a Linux bridge
1238	  interface (-bbr0 on command line)
1239	* fixed EAPOL re-authentication for sessions that used PMKSA caching
1240	* changed EAP method registration to use a dynamic list of methods
1241	  instead of a static list generated at build time
1242	* fixed PMKSA cache deinitialization not to use freed memory when
1243	  removing PMKSA entries
1244	* fixed a memory leak in EAP-TTLS re-authentication
1245	* reject WPA/WPA2 message 3/4 if it does not include any valid
1246	  WPA/RSN IE
1247	* driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
1248	  if the driver does not support SIOCSIWAUTH
1249
12502006-01-29 - v0.5.1
1251	* driver_test: added better support for multiple APs and STAs by using
1252	  a directory with sockets that include MAC address for each device in
1253	  the name (driver_param=test_dir=/tmp/test)
1254	* added support for EAP expanded type (vendor specific EAP methods)
1255	* added AP_SCAN command into ctrl_iface so that ap_scan configuration
1256	  option can be changed if needed
1257	* wpa_cli/wpa_gui: skip non-socket files in control directory when
1258	  using UNIX domain sockets; this avoids selecting an incorrect
1259	  interface (e.g., a PID file could be in this directory, even though
1260	  use of this directory for something else than socket files is not
1261	  recommended)
1262	* fixed TLS library deinitialization after RSN pre-authentication not
1263	  to disable TLS library for normal authentication
1264	* driver_wext: Remove null-termination from SSID length if the driver
1265	  used it; some Linux drivers do this and they were causing problems in
1266	  wpa_supplicant not finding matching configuration block. This change
1267	  would break a case where the SSID actually ends in '\0', but that is
1268	  not likely to happen in real use.
1269	* fixed PMKSA cache processing not to trigger deauthentication if the
1270	  current PMKSA cache entry is replaced with a valid new entry
1271	* fixed PC/SC initialization for ap_scan != 1 modes (this fixes
1272	  EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
1273	  ap_scan=2)
1274
12752005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
1276	* added experimental STAKey handshake implementation for IEEE 802.11e
1277	  direct link setup (DLS); note: this is disabled by default in both
1278	  build and runtime configuration (can be enabled with CONFIG_STAKEY=y
1279	  and stakey=1)
1280	* fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
1281	  decrypt AT_ENCR_DATA attributes correctly
1282	* fixed EAP-AKA to allow resynchronization within the same session
1283	* made code closer to ANSI C89 standard to make it easier to port to
1284	  other C libraries and compilers
1285	* started moving operating system or C library specific functions into
1286	  wrapper functions defined in os.h and implemented in os_*.c to make
1287	  code more portable
1288	* wpa_supplicant can now be built with Microsoft Visual C++
1289	  (e.g., with the freely available Toolkit 2003 version or Visual
1290	  C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
1291	  example makefile for nmake
1292	* added support for using Windows registry for command line parameters
1293	  (CONFIG_MAIN=main_winsvc) and configuration data
1294	  (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
1295	  contents; this version can be run both as a Windows service and as a
1296	  normal application; 'wpasvc.exe app' to start as applicant,
1297	  'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
1298	  'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
1299	  unregister a service
1300	* made it possible to link ndis_events.exe functionality into
1301	  wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
1302	* added better support for multiple control interface backends
1303	  (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
1304	* fixed PC/SC code to use correct length for GSM AUTH command buffer
1305	  and to not use pioRecvPci with SCardTransmit() calls; these were not
1306	  causing visible problems with pcsc-lite, but Windows Winscard.dll
1307	  refused the previously used parameters; this fixes EAP-SIM and
1308	  EAP-AKA authentication using SIM/USIM card under Windows
1309	* added new event loop implementation for Windows using
1310	  WaitForMultipleObject() instead of select() in order to allow waiting
1311	  for non-socket objects; this can be selected with
1312	  CONFIG_ELOOP=eloop_win in .config
1313	* added support for selecting l2_packet implementation in .config
1314	  (CONFIG_L2_PACKET; following options are available now: linux, pcap,
1315	  winpcap, freebsd, none)
1316	* added new l2_packet implementation for WinPcap
1317	  (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
1318	  reduce latency in EAPOL receive processing from about 100 ms to about
1319	  3 ms
1320	* added support for EAP-FAST key derivation using other ciphers than
1321	  RC4-128-SHA for authentication and AES128-SHA for provisioning
1322	* added support for configuring CA certificate as DER file and as a
1323	  configuration blob
1324	* fixed private key configuration as configuration blob and added
1325	  support for using PKCS#12 as a blob
1326	* tls_gnutls: added support for using PKCS#12 files; added support for
1327	  session resumption
1328	* added support for loading trusted CA certificates from Windows
1329	  certificate store: ca_cert="cert_store://<name>", where <name> is
1330	  likely CA (Intermediate CA certificates) or ROOT (root certificates)
1331	* added C version of ndis_events.cpp and made it possible to build this
1332	  with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
1333	  easily on cross-compilation builds
1334	* added wpasvc.exe into Windows binary release; this is an alternative
1335	  version of wpa_supplicant.exe with configuration backend using
1336	  Windows registry and with the entry point designed to run as a
1337	  Windows service
1338	* integrated ndis_events.exe functionality into wpa_supplicant.exe and
1339	  wpasvc.exe and removed this additional tool from the Windows binary
1340	  release since it is not needed anymore
1341	* load winscard.dll functions dynamically when building with MinGW
1342	  since MinGW does not yet include winscard library
1343
13442005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
1345	* l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
1346	  and WinPcap to receive frames sent to PAE group address
1347	* disable EAP state machine when IEEE 802.1X authentication is not used
1348	  in order to get rid of bogus "EAP failed" messages
1349	* fixed OpenSSL error reporting to go through all pending errors to
1350	  avoid confusing reports of old errors being reported at later point
1351	  during handshake
1352	* fixed configuration file updating to not write empty variables
1353	  (e.g., proto or key_mgmt) that the file parser would not accept
1354	* fixed ADD_NETWORK ctrl_iface command to use the same default values
1355	  for variables as empty network definitions read from config file
1356	  would get
1357	* fixed EAP state machine to not discard EAP-Failure messages in many
1358	  cases (e.g., during TLS handshake)
1359	* fixed a infinite loop in private key reading if the configured file
1360	  cannot be parsed successfully
1361	* driver_madwifi: added support for madwifi-ng
1362	* wpa_gui: do not display password/PSK field contents
1363	* wpa_gui: added CA certificate configuration
1364	* driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
1365	* driver_ndis: include Beacon IEs in AssocInfo in order to notice if
1366	  the new AP is using different WPA/RSN IE
1367	* use longer timeout for IEEE 802.11 association to avoid problems with
1368	  drivers that may take more than five second to associate
1369
13702005-10-27 - v0.4.6
1371	* allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
1372	  RSN IE, but WPA IE would match with wpa_supplicant configuration
1373	* added support for named configuration blobs in order to avoid having
1374	  to use file system for external files (e.g., certificates);
1375	  variables can be set to "blob://<blob name>" instead of file path to
1376	  use a named blob; supported fields: pac_file, client_cert,
1377	  private_key
1378	* fixed RSN pre-authentication (it was broken in the clean up of WPA
1379	  state machine interface in v0.4.5)
1380	* driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
1381	  sure the driver configures broadcast decryption correctly
1382	* added ca_path (and ca_path2) configuration variables that can be used
1383	  to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
1384	  system-wide trusted CA list
1385	* added support for starting wpa_supplicant without a configuration
1386	  file (-C argument must be used to set ctrl_interface parameter for
1387	  this case; in addition, -p argument can be used to provide
1388	  driver_param; these new arguments can also be used with a
1389	  configuration to override the values from the configuration)
1390	* added global control interface that can be optionally used for adding
1391	  and removing network interfaces dynamically (-g command line argument
1392	  for both wpa_supplicant and wpa_cli) without having to restart
1393	  wpa_supplicant process
1394	* wpa_gui:
1395	  - try to save configuration whenever something is modified
1396	  - added WEP key configuration
1397	  - added possibility to edit the current network configuration
1398	* driver_ndis: fixed driver polling not to increase frequency on each
1399	  received EAPOL frame due to incorrectly cancelled timeout
1400	* added simple configuration file examples (in examples subdirectory)
1401	* fixed driver_wext.c to filter wireless events based on ifindex to
1402	  avoid interfaces receiving events from other interfaces
1403	* delay sending initial EAPOL-Start couple of seconds to speed up
1404	  authentication for the most common case of Authenticator starting
1405	  EAP authentication immediately after association
1406
14072005-09-25 - v0.4.5
1408	* added a workaround for clearing keys with ndiswrapper to allow
1409	  roaming from WPA enabled AP to plaintext one
1410	* added docbook documentation (doc/docbook) that can be used to
1411	  generate, e.g., man pages
1412	* l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
1413	  PF_PACKET in order to prepare for network devices that do not use
1414	  Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
1415	* use receipt of EAPOL-Key frame as a lower layer success indication
1416	  for EAP state machine to allow recovery from dropped EAP-Success
1417	  frame
1418	* cleaned up internal EAPOL frame processing by not including link
1419	  layer (Ethernet) header during WPA and EAPOL/EAP processing; this
1420	  header is added only when transmitted the frame; this makes it easier
1421	  to use wpa_supplicant on link layers that use different header than
1422	  Ethernet
1423	* updated EAP-PSK to use draft 9 by default since this can now be
1424	  tested with hostapd; removed support for draft 3, including
1425	  server_nai configuration option from network blocks
1426	* driver_wired: add PAE address to the multicast address list in order
1427	  to be able to receive EAPOL frames with drivers that do not include
1428	  these multicast addresses by default
1429	* driver_wext: add support for WE-19
1430	* added support for multiple configuration backends (CONFIG_BACKEND
1431	  option); currently, only 'file' is supported (i.e., the format used
1432	  in wpa_supplicant.conf)
1433	* added support for updating configuration ('wpa_cli save_config');
1434	  this is disabled by default and can be enabled with global
1435	  update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
1436	  and wpa_gui to store the configuration changes in a permanent store
1437	* added GET_NETWORK ctrl_iface command
1438	  (e.g., 'wpa_cli get_network 0 ssid')
1439
14402005-08-21 - v0.4.4
1441	* replaced OpenSSL patch for EAP-FAST support
1442	  (openssl-tls-extensions.patch) with a more generic and correct
1443	  patch (the new patch is not compatible with the previous one, so the
1444	  OpenSSL library will need to be patched with the new patch in order
1445	  to be able to build wpa_supplicant with EAP-FAST support)
1446	* added support for using Windows certificate store (through CryptoAPI)
1447	  for client certificate and private key operations (EAP-TLS)
1448	  (see wpa_supplicant.conf for more information on how to configure
1449	  this with private_key)
1450	* ported wpa_gui to Windows
1451	* added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
1452	  built with the open source version of the Qt4 for Windows
1453	* allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
1454	  with drivers that do not support WPA
1455	* ndis_events: fixed Windows 2000 support
1456	* added support for enabling/disabling networks from the list of all
1457	  configured networks ('wpa_cli enable_network <network id>' and
1458	  'wpa_cli disable_network <network id>')
1459	* added support for adding and removing network from the current
1460	  configuration ('wpa_cli add_network' and 'wpa_cli remove_network
1461	  <network id>'); added networks are disabled by default and they can
1462	  be enabled with enable_network command once the configuration is done
1463	  for the new network; note: configuration file is not yet updated, so
1464	  these new networks are lost when wpa_supplicant is restarted
1465	* added support for setting network configuration parameters through
1466	  the control interface, for example:
1467	  wpa_cli set_network 0 ssid "\"my network\""
1468	* fixed parsing of strings that include both " and # within double
1469	  quoted area (e.g., "start"#end")
1470	* added EAP workaround for PEAP session resumption: allow outer,
1471	  i.e., not tunneled, EAP-Success to terminate session since; this can
1472	  be disabled with eap_workaround=0
1473	  (this was allowed for PEAPv1 before, but now it is also allowed for
1474	  PEAPv0 since at least one RADIUS authentication server seems to be
1475	  doing this for PEAPv0, too)
1476	* wpa_gui: added preliminary support for adding new networks to the
1477	  wpa_supplicant configuration (double click on the scan results to
1478	  open network configuration)
1479
14802005-06-26 - v0.4.3
1481	* removed interface for external EAPOL/EAP supplicant (e.g.,
1482	  Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
1483	  anymore and is unlikely to be used by anyone
1484	* driver_ndis: fixed WinPcap 3.0 support
1485	* fixed build with CONFIG_DNET_PCAP=y on Linux
1486	* l2_packet: moved different implementations into separate files
1487	  (l2_packet_*.c)
1488
14892005-06-12 - v0.4.2
1490	* driver_ipw: updated driver structures to match with ipw2200-1.0.4
1491	  (note: ipw2100-1.1.0 is likely to require an update to work with
1492	  this)
1493	* added support for using ap_scan=2 mode with multiple network blocks;
1494	  wpa_supplicant will go through the networks one by one until the
1495	  driver reports a successful association; this uses the same order for
1496	  networks as scan_ssid=1 scans, i.e., the priority field is ignored
1497	  and the network block order in the file is used instead
1498	* fixed a potential issue in RSN pre-authentication ending up using
1499	  freed memory if pre-authentication times out
1500	* added support for matching alternative subject name extensions of the
1501	  authentication server certificate; new configuration variables
1502	  altsubject_match and altsubject_match2
1503	* driver_ndis: added support for IEEE 802.1X authentication with wired
1504	  NDIS drivers
1505	* added support for querying private key password (EAP-TLS) through the
1506	  control interface (wpa_cli/wpa_gui) if one is not included in the
1507	  configuration file
1508	* driver_broadcom: fixed couple of memory leaks in scan result
1509	  processing
1510	* EAP-PAX is now registered as EAP type 46
1511	* fixed EAP-PAX MAC calculation
1512	* fixed EAP-PAX CK and ICK key derivation
1513	* added support for using password with EAP-PAX (as an alternative to
1514	  entering key with eappsk); SHA-1 hash of the password will be used as
1515	  the key in this case
1516	* added support for arbitrary driver interface parameters through the
1517	  configuration file with a new driver_param field; this adds a new
1518	  driver_ops function set_param()
1519	* added possibility to override l2_packet module with driver interface
1520	  API (new send_eapol handler); this can be used to implement driver
1521	  specific TX/RX functions for EAPOL frames
1522	* fixed ctrl_interface_group processing for the case where gid is
1523	  entered as a number, not group name
1524	* driver_test: added support for testing hostapd with wpa_supplicant
1525	  by using test driver interface without any kernel drivers or network
1526	  cards
1527
15282005-05-22 - v0.4.1
1529	* driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
1530	  packets to be encrypted; this was apparently broken by the changed
1531	  ioctl order in v0.4.0
1532	* driver_madwifi: added preliminary support for compiling against 'BSD'
1533	  branch of madwifi CVS tree
1534	* added support for EAP-MSCHAPv2 password retries within the same EAP
1535	  authentication session
1536	* added support for password changes with EAP-MSCHAPv2 (used when the
1537	  password has expired)
1538	* added support for reading additional certificates from PKCS#12 files
1539	  and adding them to the certificate chain
1540	* fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
1541	  were used
1542	* fixed a possible double free in EAP-TTLS fast-reauthentication when
1543	  identity or password is entered through control interface
1544	* display EAP Notification messages to user through control interface
1545	  with "CTRL-EVENT-EAP-NOTIFICATION" prefix
1546	* added GUI version of wpa_cli, wpa_gui; this is not build
1547	  automatically with 'make'; use 'make wpa_gui' to build (this requires
1548	  Qt development tools)
1549	* added 'disconnect' command to control interface for setting
1550	  wpa_supplicant in state where it will not associate before
1551	  'reassociate' command has been used
1552	* added support for selecting a network from the list of all configured
1553	  networks ('wpa_cli select_network <network id>'; this disabled all
1554	  other networks; to re-enable, 'wpa_cli select_network any')
1555	* added support for getting scan results through control interface
1556	* added EAP workaround for PEAPv1 session resumption: allow outer,
1557	  i.e., not tunneled, EAP-Success to terminate session since; this can
1558	  be disabled with eap_workaround=0
1559
15602005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
1561	* added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
1562	  used to reduce the size of the wpa_supplicant considerably if
1563	  debugging code is not needed
1564	* fixed EAPOL-Key validation to drop packets with invalid Key Data
1565	  Length; such frames could have crashed wpa_supplicant due to buffer
1566	  overflow
1567	* added support for wired authentication (IEEE 802.1X on wired
1568	  Ethernet); driver interface 'wired'
1569	* obsoleted set_wpa() handler in the driver interface API (it can be
1570	  replaced by moving enable/disable functionality into init()/deinit())
1571	  (calls to set_wpa() are still present for backwards compatibility,
1572	  but they may be removed in the future)
1573	* driver_madwifi: fixed association in plaintext mode
1574	* modified the EAP workaround that accepts EAP-Success with incorrect
1575	  Identifier to be even less strict about verification in order to
1576	  interoperate with some authentication servers
1577	* added support for sending TLS alerts
1578	* added support for 'any' SSID wildcard; if ssid is not configured or
1579	  is set to an empty string, any SSID will be accepted for non-WPA AP
1580	* added support for asking PIN (for SIM) from frontends (e.g.,
1581	  wpa_cli); if a PIN is needed, but not included in the configuration
1582	  file, a control interface request is sent and EAP processing is
1583	  delayed until the PIN is available
1584	* added support for using external devices (e.g., a smartcard) for
1585	  private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
1586	  new wpa_supplicant.conf variables:
1587	  - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
1588	  - network: engine, engine_id, key_id
1589	* added experimental support for EAP-PAX
1590	* added monitor mode for wpa_cli (-a<path to a program to run>) that
1591	  allows external commands (e.g., shell scripts) to be run based on
1592	  wpa_supplicant events, e.g., when authentication has been completed
1593	  and data connection is ready; other related wpa_cli arguments:
1594	  -B (run in background), -P (write PID file); wpa_supplicant has a new
1595	  command line argument (-W) that can be used to make it wait until a
1596	  control interface command is received in order to avoid missing
1597	  events
1598	* added support for opportunistic WPA2 PMKSA key caching (disabled by
1599	  default, can be enabled with proactive_key_caching=1)
1600	* fixed RSN IE in 4-Way Handshake message 2/4 for the case where
1601	  Authenticator rejects PMKSA caching attempt and the driver is not
1602	  using assoc_info events
1603	* added -P<pid file> argument for wpa_supplicant to write the current
1604	  process id into a file
1605
16062005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
1607	* added new phase1 option parameter, include_tls_length=1, to force
1608	  wpa_supplicant to add TLS Message Length field to all TLS messages
1609	  even if the packet is not fragmented; this may be needed with some
1610	  authentication servers
1611	* fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
1612	  using drivers that take care of AP selection (e.g., when using
1613	  ap_scan=2)
1614	* fixed reprocessing of pending request after ctrl_iface requests for
1615	  identity/password/otp
1616	* fixed ctrl_iface requests for identity/password/otp in Phase 2 of
1617	  EAP-PEAP and EAP-TTLS
1618	* all drivers using driver_wext: set interface up and select Managed
1619	  mode when starting wpa_supplicant; set interface down when exiting
1620	* renamed driver_ipw2100.c to driver_ipw.c since it now supports both
1621	  ipw2100 and ipw2200; please note that this also changed the
1622	  configuration variable in .config to CONFIG_DRIVER_IPW
1623
16242005-01-24 - v0.3.6
1625	* fixed a busy loop introduced in v0.3.5 for scan result processing
1626	  when no matching AP is found
1627
16282005-01-23 - v0.3.5
1629	* added a workaround for an interoperability issue with a Cisco AP
1630	  when using WPA2-PSK
1631	* fixed non-WPA IEEE 802.1X to use the same authentication timeout as
1632	  WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
1633	  retransmission of dropped frames)
1634	* fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
1635	  (e.g., segfault when processing EAPOL-Key frames)
1636	* fixed EAP workaround and fast reauthentication configuration for
1637	  RSN pre-authentication; previously these were disabled and
1638	  pre-authentication would fail if the used authentication server
1639	  requires EAP workarounds
1640	* added support for blacklisting APs that fail or timeout
1641	  authentication in ap_scan=1 mode so that all APs are tried in cases
1642	  where the ones with strongest signal level are failing authentication
1643	* fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
1644	  authentication attempt
1645	* allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
1646	  in the previous authentication (previously, only Phase 1 success was
1647	  verified)
1648
16492005-01-09 - v0.3.4
1650	* added preliminary support for IBSS (ad-hoc) mode configuration
1651	  (mode=1 in network block); this included a new key_mgmt mode
1652	  WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
1653	  key management; see wpa_supplicant.conf for more details and an
1654	  example on how to configure this (note: this is currently implemented
1655	  only for driver_hostapd.c, but the changes should be trivial to add
1656	  in associate() handler for other drivers, too (assuming the driver
1657	  supports WPA-None)
1658	* added preliminary port for native Windows (i.e., no cygwin) using
1659	  mingw
1660
16612005-01-02 - v0.3.3
1662	* added optional support for GNU Readline and History Libraries for
1663	  wpa_cli (CONFIG_READLINE)
1664	* cleaned up EAP state machine <-> method interface and number of
1665	  small problems with error case processing not terminating on
1666	  EAP-Failure but waiting for timeout
1667	* added couple of workarounds for interoperability issues with a
1668	  Cisco AP when using WPA2
1669	* added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
1670	  Note: This requires a patch for openssl to add support for TLS
1671	  extensions and number of workarounds for operations without
1672	  certificates. Proof of concept type of experimental patch is
1673	  included in openssl-tls-extensions.patch.
1674
16752004-12-19 - v0.3.2
1676	* fixed private key loading for cases where passphrase is not set
1677	* fixed Windows/cygwin L2 packet handler freeing; previous version
1678	  could cause a segfault when RSN pre-authentication was completed
1679	* added support for PMKSA caching with drivers that generate RSN IEs
1680	  (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
1681	  but similar code can be easily added to driver_ndiswrapper.c once
1682	  ndiswrapper gets full support for RSN PMKSA caching
1683	* improved recovery from PMKID mismatches by requesting full EAP
1684	  authentication in case of failed PMKSA caching attempt
1685	* driver_ndis: added support for NDIS NdisMIncidateStatus() events
1686	  (this requires that ndis_events is ran while wpa_supplicant is
1687	  running)
1688	* driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
1689	* added support for driver interfaces to replace the interface name
1690	  based on driver/OS specific mapping, e.g., in case of driver_ndis,
1691	  this allows the beginning of the adapter description to be used as
1692	  the interface name
1693	* added support for CR+LF (Windows-style) line ends in configuration
1694	  file
1695	* driver_ndis: enable radio before starting scanning, disable radio
1696	  when exiting
1697	* modified association event handler to set portEnabled = FALSE before
1698	  clearing port Valid in order to reset EAP state machine and avoid
1699	  problems with new authentication getting ignored because of state
1700	  machines ending up in AUTHENTICATED/SUCCESS state based on old
1701	  information
1702	* added support for driver events to add PMKID candidates in order to
1703	  allow drivers to give priority to most likely roaming candidates
1704	* driver_hostap: moved PrivacyInvoked configuration to associate()
1705	  function so that this will not be set for plaintext connections
1706	* added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
1707	  interface can distinguish plaintext and IEEE 802.1X (no WPA)
1708	  authentication
1709	* fixed static WEP key configuration to use broadcast/default type for
1710	  all keys (previously, the default TX key was configured as pairwise/
1711	  unicast key)
1712	* driver_ndis: added legacy WPA capability detection for non-WPA2
1713	  drivers
1714	* added support for setting static WEP keys for IEEE 802.1X without
1715	  dynamic WEP keying (eapol_flags=0)
1716
17172004-12-12 - v0.3.1
1718	* added support for reading PKCS#12 (PFX) files (as a replacement for
1719	  PEM/DER) to get certificate and private key (CONFIG_PKCS12)
1720	* fixed compilation with CONFIG_PCSC=y
1721	* added new ap_scan mode, ap_scan=2, for drivers that take care of
1722	  association, but need to be configured with security policy and SSID,
1723	  e.g., ndiswrapper and NDIS driver; this mode should allow such
1724	  drivers to work with hidden SSIDs and optimized roaming; when
1725	  ap_scan=2 is used, only the first network block in the configuration
1726	  file is used and this configuration should have explicit security
1727	  policy (i.e., only one option in the lists) for key_mgmt, pairwise,
1728	  group, proto variables
1729	* added experimental port of wpa_supplicant for Windows
1730	  - driver_ndis.c driver interface (NDIS OIDs)
1731	  - currently, this requires cygwin and WinPcap
1732	  - small utility, win_if_list, can be used to get interface name
1733	* control interface can now be removed at build time; add
1734	  CONFIG_CTRL_IFACE=y to .config to maintain old functionality
1735	* optional Xsupplicant interface can now be removed at build time;
1736	  (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
1737	* added auth_alg to driver interface associate() parameters to make it
1738	  easier for drivers to configure authentication algorithm as part of
1739	  the association
1740
17412004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
1742	* driver_broadcom: added new driver interface for Broadcom wl.o driver
1743	  (a generic driver for Broadcom IEEE 802.11a/g cards)
1744	* wpa_cli: fixed parsing of -p <path> command line argument
1745	* PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
1746	  ACK, not tunneled EAP-Success (of which only the first byte was
1747	  actually send due to a bug in previous code); this seems to
1748	  interoperate with most RADIUS servers that implements PEAPv1
1749	* PEAPv1: added support for terminating PEAP authentication on tunneled
1750	  EAP-Success message; this can be configured by adding
1751	  peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
1752	  (some RADIUS servers require this whereas others require a tunneled
1753	  reply
1754	* PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
1755	  the old label for key derivation; previously, the default was 1,
1756	  but it looks like most existing PEAPv1 implementations use the old
1757	  label which is thus more suitable default option
1758	* added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
1759	* fixed parsing of wep_tx_keyidx
1760	* added support for configuring list of allowed Phase 2 EAP types
1761	  (for both EAP-PEAP and EAP-TTLS) instead of only one type
1762	* added support for configuring IEEE 802.11 authentication algorithm
1763	  (auth_alg; mainly for using Shared Key authentication with static
1764	  WEP keys)
1765	* added support for EAP-AKA (with UMTS SIM)
1766	* fixed couple of errors in PCSC handling that could have caused
1767	  random-looking errors for EAP-SIM
1768	* added support for EAP-SIM pseudonyms and fast re-authentication
1769	* added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
1770	  session resumption)
1771	* added support for EAP-SIM with two challanges
1772	  (phase1="sim_min_num_chal=3" can be used to require three challenges)
1773	* added support for configuring DH/DSA parameters for an ephemeral DH
1774	  key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
1775	  dh_file and dh_file2 (phase 2); this adds support for using DSA keys
1776	  and optional DH key exchange to achieve forward secracy with RSA keys
1777	* added support for matching subject of the authentication server
1778	  certificate with a substring when using EAP-TLS/PEAP/TTLS; new
1779	  configuration variables subject_match and subject_match2
1780	* changed SSID configuration in driver_wext.c (used by many driver
1781	  interfaces) to use ssid_len+1 as the length for SSID since some Linux
1782	  drivers expect this
1783	* fixed couple of unaligned reads in scan result parsing to fix WPA
1784	  connection on some platforms (e.g., ARM)
1785	* added driver interface for Intel ipw2100 driver
1786	* added support for LEAP with WPA
1787	* added support for larger scan results report (old limit was 4 kB of
1788	  data, i.e., about 35 or so APs) when using Linux wireless extensions
1789	  v17 or newer
1790	* fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
1791	  only if there is a PMKSA cache entry for the current AP
1792	* fixed error handling for case where reading of scan results fails:
1793	  must schedule a new scan or wpa_supplicant will remain waiting
1794	  forever
1795	* changed debug output to remove shared password/key material by
1796	  default; all key information can be included with -K command line
1797	  argument to match the previous behavior
1798	* added support for timestamping debug log messages (disabled by
1799	  default, can be enabled with -t command line argument)
1800	* set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
1801	  if keys are not configured to be used; this fixes IEEE 802.1X mode
1802	  with drivers that use this information to configure whether Privacy
1803	  bit can be in Beacon frames (e.g., ndiswrapper)
1804	* avoid clearing driver keys if no keys have been configured since last
1805	  key clear request; this seems to improve reliability of group key
1806	  handshake for ndiswrapper & NDIS driver which seems to be suffering
1807	  of some kind of timing issue when the keys are cleared again after
1808	  association
1809	* changed driver interface API:
1810	  - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
1811	    version is being used (now, this is set to 2; previously, it was
1812	    not defined)
1813	  - pass pointer to private data structure to all calls
1814	  - the new API is not backwards compatible; all in-tree driver
1815	    interfaces has been converted to the new API
1816	* added support for controlling multiple interfaces (radios) per
1817	  wpa_supplicant process; each interface needs to be listed on the
1818	  command line (-c, -i, -D arguments) with -N as a separator
1819	  (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
1820	* added a workaround for EAP servers that incorrectly use same Id for
1821	  sequential EAP packets
1822	* changed libpcap/libdnet configuration to use .config variable,
1823	  CONFIG_DNET_PCAP, instead of requiring Makefile modification
1824	* improved downgrade attack detection in IE verification of msg 3/4:
1825	  verify both WPA and RSN IEs, if present, not only the selected one;
1826	  reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
1827	  Probe Response frame, and RSN is enabled in wpa_supplicant
1828	  configuration
1829	* fixed WPA msg 3/4 processing to allow Key Data field contain other
1830	  IEs than just one WPA IE
1831	* added support for FreeBSD and driver interface for the BSD net80211
1832	  layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
1833	  required kernel mods have not yet been committed
1834	* made EAP workarounds configurable; enabled by default, can be
1835	  disabled with network block option eap_workaround=0
1836
18372004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
1838	* resolved couple of interoperability issues with EAP-PEAPv1 and
1839	  Phase 2 (inner EAP) fragment reassembly
1840	* driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
1841	  AP is using non-zero key index for the unicast key and key index zero
1842	  for the broadcast key
1843	* driver_hostap: fixed IEEE 802.1X WEP key updates and
1844	  re-authentication by allowing unencrypted EAPOL frames when not using
1845	  WPA
1846	* added a new driver interface, 'wext', which uses only standard,
1847	  driver independent functionality in Linux wireless extensions;
1848	  currently, this can be used only for non-WPA IEEE 802.1X mode, but
1849	  eventually, this is to be extended to support full WPA/WPA2 once
1850	  Linux wireless extensions get support for this
1851	* added support for mode in which the driver is responsible for AP
1852	  scanning and selection; this is disabled by default and can be
1853	  enabled with global ap_scan=0 variable in wpa_supplicant.conf;
1854	  this mode can be used, e.g., with generic 'wext' driver interface to
1855	  use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
1856	  supporting wireless extensions.
1857	* driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
1858	  operation with an AP that does not include SSID in the Beacon frames)
1859	* added support for new EAP authentication methods:
1860	  EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
1861	* added support for asking one-time-passwords from frontends (e.g.,
1862	  wpa_cli); this 'otp' command works otherwise like 'password' command,
1863	  but the password is used only once and the frontend will be asked for
1864	  a new password whenever a request from authenticator requires a
1865	  password; this can be used with both EAP-OTP and EAP-GTC
1866	* changed wpa_cli to automatically re-establish connection so that it
1867	  does not need to be re-started when wpa_supplicant is terminated and
1868	  started again
1869	* improved user data (identity/password/otp) requests through
1870	  frontends: process pending EAPOL packets after getting new
1871	  information so that full authentication does not need to be
1872	  restarted; in addition, send pending requests again whenever a new
1873	  frontend is attached
1874	* changed control frontends to use a new directory for socket files to
1875	  make it easier for wpa_cli to automatically select between interfaces
1876	  and to provide access control for the control interface;
1877	  wpa_supplicant.conf: ctrl_interface is now a path
1878	  (/var/run/wpa_supplicant is the recommended path) and
1879	  ctrl_interface_group can be used to select which group gets access to
1880	  the control interface;
1881	  wpa_cli: by default, try to connect to the first interface available
1882	  in /var/run/wpa_supplicant; this path can be overriden with -p option
1883	  and an interface can be selected with -i option (i.e., in most common
1884	  cases, wpa_cli does not need to get any arguments)
1885	* added support for LEAP
1886	* added driver interface for Linux ndiswrapper
1887	* added priority option for network blocks in the configuration file;
1888	  this allows networks to be grouped based on priority (the scan
1889	  results are searched for matches with network blocks in this order)
1890
18912004-06-20 - v0.2.3
1892	* sort scan results to improve AP selection
1893	* fixed control interface socket removal for some error cases
1894	* improved scan requesting and authentication timeout
1895	* small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1896	  TLS processing
1897	* PEAP version can now be forced with phase1="peapver=<ver>"
1898	  (mostly for testing; by default, the highest version supported by
1899	  both the Supplicant and Authentication Server is selected
1900	  automatically)
1901	* added support for madwifi driver (Atheros ar521x)
1902	* added a workaround for cases where AP sets Install Tx/Rx bit for
1903	  WPA Group Key messages when pairwise keys are used (without this,
1904	  the Group Key would be used for Tx and the AP would drop frames
1905	  from the station)
1906	* added GSM SIM/USIM interface for GSM authentication algorithm for
1907	  EAP-SIM; this requires pcsc-lite
1908	* added support for ATMEL AT76C5XXx driver
1909	* fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1910	  does not include key data in the EAPOL-Key frame (i.e., part of
1911	  EAP keying material is used as data encryption key)
1912	* added support for using plaintext and static WEP networks
1913	  (key_mgmt=NONE)
1914
19152004-05-31 - v0.2.2
1916	* added support for new EAP authentication methods:
1917	  EAP-TTLS/EAP-MD5-Challenge
1918	  EAP-TTLS/EAP-GTC
1919	  EAP-TTLS/EAP-MSCHAPv2
1920	  EAP-TTLS/EAP-TLS
1921	  EAP-TTLS/MSCHAPv2
1922	  EAP-TTLS/MSCHAP
1923	  EAP-TTLS/PAP
1924	  EAP-TTLS/CHAP
1925	  EAP-PEAP/TLS
1926	  EAP-PEAP/GTC
1927	  EAP-PEAP/MD5-Challenge
1928	  EAP-GTC
1929	  EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1930	* added support for anonymous identity (to be used when identity is
1931	  sent in plaintext; real identity will be used within TLS protected
1932	  tunnel (e.g., with EAP-TTLS)
1933	* added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1934	* added support for requesting identity and password information using
1935	  control interface; in other words, the password for EAP-PEAP or
1936	  EAP-TTLS does not need to be included in the configuration file since
1937	  a frontand (e.g., wpa_cli) can ask it from the user
1938	* improved RSN pre-authentication to use a candidate list and process
1939	  all candidates from each scan; not only one per scan
1940	* fixed RSN IE and WPA IE capabilities field parsing
1941	* ignore Tx bit in GTK IE when Pairwise keys are used
1942	* avoid making new scan requests during IEEE 802.1X negotiation
1943	* use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1944	  with TLS support (this replaces the included implementation with
1945	  library code to save about 8 kB since the library code is needed
1946	  anyway for TLS)
1947	* fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1948	  (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1949
19502004-05-06 - v0.2.1
1951	* added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1952	  Supplicant
1953	  - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1954	  - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1955	  - EAP-MD5 (cannot be used with WPA-RADIUS)
1956	    [draft-ietf-eap-rfc2284bis-09.txt]
1957	  - EAP-TLS [RFC 2716]
1958	  - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1959	  - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1960	    [draft-kamath-pppext-eap-mschapv2-00.txt]
1961	    (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1962	    default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1963	  - new configuration file options: eap, identity, password, ca_cert,
1964	    client_cert, privatekey, private_key_passwd
1965	  - Xsupplicant is not required anymore, but it can be used by
1966	    disabling the internal IEEE 802.1X Supplicant with -e command line
1967	    option
1968	  - this code is not included in the default build; Makefile need to
1969	    be edited for this (uncomment lines for selected functionality)
1970	  - EAP-TLS and EAP-PEAP require openssl libraries
1971	* use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1972	* added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1973	  (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1974	   EAPOL-Key frames instead of WPA key handshakes)
1975	* added support for IEEE 802.11i/RSN (WPA2)
1976	  - improved PTK Key Handshake
1977	  - PMKSA caching, pre-authentication
1978	* fixed wpa_supplicant to ignore possible extra data after WPA
1979	  EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1980	  TPTK' error from message 3 of 4-Way Handshake in case the AP
1981	  includes extra data after the EAPOL-Key)
1982	* added interface for external programs (frontends) to control
1983	  wpa_supplicant
1984	  - CLI example (wpa_cli) with interactive mode and command line
1985	    mode
1986	  - replaced SIGUSR1 status/statistics with the new control interface
1987	* made some feature compile time configurable
1988	  - .config file for make
1989	  - driver interfaces (hostap, hermes, ..)
1990	  - EAPOL/EAP functions
1991
19922004-02-15 - v0.2.0
1993	* Initial version of wpa_supplicant
