411	    round
412	  - these optional arguments to the SCAN command can be combined with
413	    each other
414	* modified behavior on externally triggered scans

720	    before requesting a new scan after failing to find a suitable
721	    network in scan results) using scan_interval command.
722	  - Add event CTRL-EVENT-ASSOC-REJECT for association rejected.
723	  - Add command get version, that returns wpa_supplicant version string.
724	  - Add command sta_autoconnect for disabling automatic reconnection
725	    on receiving disconnection event.

776	    be compatible with Windows 7.
777	  - Add Config Error into WPS-FAIL events to provide more info to the
778	    user on how to resolve the issue.
779	  - Label and Display config methods are not allowed to be enabled

781	    methods are advertised.
782	  - When controlling multiple interfaces:
783	     - apply WPS commands to all interfaces configured to use WPS
784	     - apply WPS config changes to all interfaces that use WPS

807	    explicitly not supported, disable all user facing TDLS operations.
808	  - Allow TDLS to be disabled at runtime (mostly for testing).
809	    Use set tdls_disabled.

839	* Wi-Fi Direct support. See README-P2P for more information.
840	* Many bugfixes.
841
8422010-04-18 - v0.7.2
843	* nl80211: fixed number of issues with roaming
844	* avoid unnecessary roaming if multiple APs with similar signal
845	  strength are present in scan results
846	* add TLS client events and server probing to ease design of
847	  automatic detection of EAP parameters
848	* add option for server certificate matching (SHA256 hash of the
849	  certificate) instead of trusted CA certificate configuration
850	* bsd: Cleaned up driver wrapper and added various low-level
851	  configuration options
852	* wpa_gui-qt4: do not show too frequent WPS AP available events as
853	  tray messages
854	* TNC: fixed issues with fragmentation
855	* EAP-TNC: add Flags field into fragment acknowledgement (needed to
856	  interoperate with other implementations; may potentially breaks
857	  compatibility with older wpa_supplicant/hostapd versions)
858	* wpa_cli: added option for using a separate process to receive event
859	  messages to reduce latency in showing these
860	  (CFLAGS += -DCONFIG_WPA_CLI_FORK=y in .config to enable this)
861	* maximum BSS table size can now be configured (bss_max_count)
862	* BSSes to be included in the BSS table can be filtered based on
863	  configured SSIDs to save memory (filter_ssids)
864	* fix number of issues with IEEE 802.11r/FT; this version is not
865	  backwards compatible with old versions
866	* nl80211: add support for IEEE 802.11r/FT protocol (both over-the-air
867	  and over-the-DS)
868	* add freq_list network configuration parameter to allow the AP
869	  selection to filter out entries based on the operating channel
870	* add signal strength change events for bgscan; this allows more
871	  dynamic changes to background scanning interval based on changes in
872	  the signal strength with the current AP; this improves roaming within
873	  ESS quite a bit, e.g., with bgscan="simple:30:-45:300" in the network
874	  configuration block to request background scans less frequently when
875	  signal strength remains good and to automatically trigger background
876	  scans whenever signal strength drops noticeably
877	  (this is currently only available with nl80211)
878	* add BSSID and reason code (if available) to disconnect event messages
879	* wpa_gui-qt4: more complete support for translating the GUI with
880	  linguist and add German translation
881	* fix DH padding with internal crypto code (mainly, for WPS)
882	* do not trigger initial scan automatically anymore if there are no
883	  enabled networks
884
8852010-01-16 - v0.7.1
886	* cleaned up driver wrapper API (struct wpa_driver_ops); the new API
887	  is not fully backwards compatible, so out-of-tree driver wrappers
888	  will need modifications
889	* cleaned up various module interfaces
890	* merge hostapd and wpa_supplicant developers' documentation into a
891	  single document
892	* nl80211: use explicit deauthentication to clear cfg80211 state to
893	  avoid issues when roaming between APs
894	* dbus: major design changes in the new D-Bus API
895	  (fi.w1.wpa_supplicant1)
896	* nl80211: added support for IBSS networks
897	* added internal debugging mechanism with backtrace support and memory
898	  allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y)
899	* added WPS ER unsubscription command to more cleanly unregister from
900	  receiving UPnP events when ER is terminated
901	* cleaned up AP mode operations to avoid need for virtual driver_ops
902	  wrapper
903	* added BSS table to maintain more complete scan result information
904	  over multiple scans (that may include only partial results)
905	* wpa_gui-qt4: update Peers dialog information more dynamically while
906	  the dialog is kept open
907	* fixed PKCS#12 use with OpenSSL 1.0.0
908	* driver_wext: Added cfg80211-specific optimization to avoid some
909	  unnecessary scans and to speed up association
910
9112009-11-21 - v0.7.0
912	* increased wpa_cli ping interval to 5 seconds and made this
913	  configurable with a new command line options (-G<seconds>)
914	* fixed scan buffer processing with WEXT to handle up to 65535
915	  byte result buffer (previously, limited to 32768 bytes)
916	* allow multiple driver wrappers to be specified on command line
917	  (e.g., -Dnl80211,wext); the first one that is able to initialize the
918	  interface will be used
919	* added support for multiple SSIDs per scan request to optimize
920	  scan_ssid=1 operations in ap_scan=1 mode (i.e., search for hidden
921	  SSIDs); this requires driver support and can currently be used only
922	  with nl80211
923	* added support for WPS USBA out-of-band mechanism with USB Flash
924	  Drives (UFD) (CONFIG_WPS_UFD=y)
925	* driver_ndis: add PAE group address to the multicast address list to
926	  fix wired IEEE 802.1X authentication
927	* fixed IEEE 802.11r key derivation function to match with the standard
928	  (note: this breaks interoperability with previous version) [Bug 303]
929	* added better support for drivers that allow separate authentication
930	  and association commands (e.g., mac80211-based Linux drivers with
931	  nl80211; SME in wpa_supplicant); this allows over-the-air FT protocol
932	  to be used (IEEE 802.11r)
933	* fixed SHA-256 based key derivation function to match with the
934	  standard when using CCMP (for IEEE 802.11r and IEEE 802.11w)
935	  (note: this breaks interoperability with previous version) [Bug 307]
936	* use shared driver wrapper files with hostapd
937	* added AP mode functionality (CONFIG_AP=y) with mode=2 in the network
938	  block; this can be used for open and WPA2-Personal networks
939	  (optionally, with WPS); this links in parts of hostapd functionality
940	  into wpa_supplicant
941	* wpa_gui-qt4: added new Peers dialog to show information about peers
942	  (other devices, including APs and stations, etc. in the neighborhood)
943	* added support for WPS External Registrar functionality (configure APs
944	  and enroll new devices); can be used with wpa_gui-qt4 Peers dialog
945	  and wpa_cli commands wps_er_start, wps_er_stop, wps_er_pin,
946	  wps_er_pbc, wps_er_learn
947	  (this can also be used with a new 'none' driver wrapper if no
948	  wireless device or IEEE 802.1X on wired is needed)
949	* driver_nl80211: multiple updates to provide support for new Linux
950	  nl80211/mac80211 functionality
951	* updated management frame protection to use IEEE Std 802.11w-2009
952	* fixed number of small WPS issues and added workarounds to
953	  interoperate with common deployed broken implementations
954	* added support for NFC out-of-band mechanism with WPS
955	* driver_ndis: fixed wired IEEE 802.1X authentication with PAE group
956	  address frames
957	* added preliminary support for IEEE 802.11r RIC processing
958	* added support for specifying subset of enabled frequencies to scan
959	  (scan_freq option in the network configuration block); this can speed
960	  up scanning process considerably if it is known that only a small
961	  subset of channels is actually used in the network (this is currently
962	  supported only with -Dnl80211)
963	* added a workaround for race condition between receiving the
964	  association event and the following EAPOL-Key
965	* added background scan and roaming infrastructure to allow
966	  network-specific optimizations to be used to improve roaming within
967	  an ESS (same SSID)
968	* added new DBus interface (fi.w1.wpa_supplicant1)
969
9702009-01-06 - v0.6.7
971	* added support for Wi-Fi Protected Setup (WPS)
972	  (wpa_supplicant can now be configured to act as a WPS Enrollee to
973	  enroll credentials for a network using PIN and PBC methods; in
974	  addition, wpa_supplicant can act as a wireless WPS Registrar to
975	  configure an AP); WPS support can be enabled by adding CONFIG_WPS=y
976	  into .config and setting the runtime configuration variables in
977	  wpa_supplicant.conf (see WPS section in the example configuration
978	  file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to
979	  manage WPS negotiation; see README-WPS for more details
980	* added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
981	* added support for using driver_test over UDP socket
982	* fixed PEAPv0 Cryptobinding interoperability issue with Windows Server
983	  2008 NPS; optional cryptobinding is now enabled (again) by default
984	* fixed PSK editing in wpa_gui
985	* changed EAP-GPSK to use the IANA assigned EAP method type 51
986	* added a Windows installer that includes WinPcap and all the needed
987	  DLLs; in addition, it set up the registry automatically so that user
988	  will only need start wpa_gui to get prompted to start the wpasvc
989	  servide and add a new interface if needed through wpa_gui dialog
990	* updated management frame protection to use IEEE 802.11w/D7.0
991
9922008-11-23 - v0.6.6
993	* added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
994	  (can be used to simulate test SIM/USIM card with a known private key;
995	  enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
996	  and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
997	* added a new network configuration option, wpa_ptk_rekey, that can be
998	  used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
999	  against TKIP deficiencies
1000	* added an optional mitigation mechanism for certain attacks against
1001	  TKIP by delaying Michael MIC error reports by a random amount of time
1002	  between 0 and 60 seconds; this can be enabled with a build option
1003	  CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
1004	* fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
1005	  not bytes
1006	* updated OpenSSL code for EAP-FAST to use an updated version of the
1007	  session ticket overriding API that was included into the upstream
1008	  OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
1009	  needed with that version anymore)
1010	* updated userspace MLME instructions to match with the current Linux
1011	  mac80211 implementation; please also note that this can only be used
1012	  with driver_nl80211.c (the old code from driver_wext.c was removed)
1013	* added support (Linux only) for RoboSwitch chipsets (often found in
1014	  consumer grade routers); driver interface 'roboswitch'
1015	* fixed canceling of PMKSA caching when using drivers that generate
1016	  RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
1017	  about
1018
10192008-11-01 - v0.6.5
1020	* added support for SHA-256 as X.509 certificate digest when using the
1021	  internal X.509/TLSv1 implementation
1022	* updated management frame protection to use IEEE 802.11w/D6.0
1023	* added support for using SHA256-based stronger key derivation for WPA2
1024	  (IEEE 802.11w)
1025	* fixed FT (IEEE 802.11r) authentication after a failed association to
1026	  use correct FTIE
1027	* added support for configuring Phase 2 (inner/tunneled) authentication
1028	  method with wpa_gui-qt4
1029
10302008-08-10 - v0.6.4
1031	* added support for EAP Sequences in EAP-FAST Phase 2
1032	* added support for using TNC with EAP-FAST
1033	* added driver_ps3 for the PS3 Linux wireless driver
1034	* added support for optional cryptobinding with PEAPv0
1035	* fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
1036	  allow fallback to full handshake if server rejects PAC-Opaque
1037	* added fragmentation support for EAP-TNC
1038	* added support for parsing PKCS #8 formatted private keys into the
1039	  internal TLS implementation (both PKCS #1 RSA key and PKCS #8
1040	  encapsulated RSA key can now be used)
1041	* added option of using faster, but larger, routines in the internal
1042	  LibTomMath (for internal TLS implementation) to speed up DH and RSA
1043	  calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
1044	* fixed race condition between disassociation event and group key
1045	  handshake to avoid getting stuck in incorrect state [Bug 261]
1046	* fixed opportunistic key caching (proactive_key_caching)
1047
10482008-02-22 - v0.6.3
1049	* removed 'nai' and 'eappsk' network configuration variables that were
1050	  previously used for configuring user identity and key for EAP-PSK,
1051	  EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
1052	  replacement for 'nai' (if old configuration used a separate
1053	  'identity' value, that would now be configured as
1054	  'anonymous_identity'). 'password' field is now used as the
1055	  replacement for 'eappsk' (it can also be set using hexstring to
1056	  present random binary data)
1057	* removed '-w' command line parameter (wait for interface to be added,
1058	  if needed); cleaner way of handling this functionality is to use an
1059	  external mechanism (e.g., hotplug scripts) that start wpa_supplicant
1060	  when an interface is added
1061	* updated FT support to use the latest draft, IEEE 802.11r/D9.0
1062	* added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
1063	  indicating when new scan results become available
1064	* added new ctrl_iface command, BSS, to allow scan results to be
1065	  fetched without hitting the message size limits (this command
1066	  can be used to iterate through the scan results one BSS at the time)
1067	* fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
1068	  attributes in EAP-SIM Start/Response when using fast reauthentication
1069	* fixed EAPOL not to end up in infinite loop when processing dynamic
1070	  WEP keys with IEEE 802.1X
1071	* fixed problems in getting NDIS events from WMI on Windows 2000
1072
10732008-01-01 - v0.6.2
1074	* added support for Makefile builds to include debug-log-to-a-file
1075	  functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
1076	* fixed EAP-SIM and EAP-AKA message parser to validate attribute
1077	  lengths properly to avoid potential crash caused by invalid messages
1078	* added data structure for storing allocated buffers (struct wpabuf);
1079	  this does not affect wpa_supplicant usage, but many of the APIs
1080	  changed and various interfaces (e.g., EAP) is not compatible with old
1081	  versions
1082	* added support for protecting EAP-AKA/Identity messages with
1083	  AT_CHECKCODE (optional feature in RFC 4187)
1084	* added support for protected result indication with AT_RESULT_IND for
1085	  EAP-SIM and EAP-AKA (phase1="result_ind=1")
1086	* added driver_wext workaround for race condition between scanning and
1087	  association with drivers that take very long time to scan all
1088	  channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
1089	  using a longer hardcoded timeout for the scan if the driver supports
1090	  notifications for scan completion (SIOCGIWSCAN event); this helps,
1091	  e.g., in cases where wpa_supplicant and madwifi driver ended up in
1092	  loop where the driver did not even try to associate
1093	* stop EAPOL timer tick when no timers are in use in order to reduce
1094	  power consumption (no need to wake up the process once per second)
1095	  [Bug 237]
1096	* added support for privilege separation (run only minimal part of
1097	  wpa_supplicant functionality as root and rest as unprivileged,
1098	  non-root process); see 'Privilege separation' in README for details;
1099	  this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
1100	  in .config
1101	* changed scan results data structure to include all information
1102	  elements to make it easier to support new IEs; old get_scan_result()
1103	  driver_ops is still supported for backwards compatibility (results
1104	  are converted internally to the new format), but all drivers should
1105	  start using the new get_scan_results2() to make them more likely to
1106	  work with new features
1107	* Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
1108	  application, i.e., it does not require Qt3Support anymore; Windows
1109	  binary of wpa_gui.exe is now from this directory and only requires
1110	  QtCore4.dll and QtGui4.dll libraries
1111	* updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
1112	  available as a separate package to make wpa_gui installation easier:
1113	  http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
1114	* added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
1115	  only shared key/password authentication is supported in this version
1116
11172007-11-24 - v0.6.1
1118	* added support for configuring password as NtPasswordHash
1119	  (16-byte MD4 hash of password) in hash:<32 hex digits> format
1120	* added support for fallback from abbreviated TLS handshake to
1121	  full handshake when using EAP-FAST (e.g., due to an expired
1122	  PAC-Opaque)
1123	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
1124	  draft (draft-ietf-emu-eap-gpsk-07.txt)
1125	* added support for drivers that take care of RSN 4-way handshake
1126	  internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
1127	  WPA_ALG_PMK in set_key)
1128	* added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
1129	  .config); this version supports only ap_scan=2 mode and allow the
1130	  driver to take care of the 4-way handshake
1131	* fixed a buffer overflow in parsing TSF from scan results when using
1132	  driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
1133	  [Bug 232]
1134	* updated FT support to use the latest draft, IEEE 802.11r/D8.0
1135	* fixed an integer overflow issue in the ASN.1 parser used by the
1136	  (experimental) internal TLS implementation to avoid a potential
1137	  buffer read overflow
1138	* fixed a race condition with -W option (wait for a control interface
1139	  monitor before starting) that could have caused the first messages to
1140	  be lost
1141	* added support for processing TNCC-TNCS-Messages to report
1142	  recommendation (allow/none/isolate) when using TNC [Bug 243]
1143
11442007-05-28 - v0.6.0
1145	* added network configuration parameter 'frequency' for setting
1146	  initial channel for IBSS (adhoc) networks
1147	* added experimental IEEE 802.11r/D6.0 support
1148	* updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
1149	* updated EAP-PSK to use the IANA-allocated EAP type 47
1150	* fixed EAP-PAX key derivation
1151	* fixed EAP-PSK bit ordering of the Flags field
1152	* fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
1153	  tunnelled identity request (previously, the identifier from the outer
1154	  method was used, not the tunnelled identifier which could be
1155	  different)
1156	* added support for fragmentation of outer TLS packets during Phase 2
1157	  of EAP-PEAP/TTLS/FAST
1158	* fixed EAP-TTLS AVP parser processing for too short AVP lengths
1159	* added support for EAP-FAST authentication with inner methods that
1160	  generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
1161	  for PAC provisioning)
1162	* added support for authenticated EAP-FAST provisioning
1163	* added support for configuring maximum number of EAP-FAST PACs to
1164	  store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
1165	* added support for storing EAP-FAST PACs in binary format
1166	  (fast_pac_format=binary in phase1 string)
1167	* fixed dbus ctrl_iface to validate message interface before
1168	  dispatching to avoid a possible segfault [Bug 190]
1169	* fixed PeerKey key derivation to use the correct PRF label
1170	* updated Windows binary build to link against OpenSSL 0.9.8d and
1171	  added support for EAP-FAST
1172	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
1173	  draft (draft-ietf-emu-eap-gpsk-04.txt)
1174	* fixed EAP-AKA Notification processing to allow Notification to be
1175	  processed after AKA Challenge response has been sent
1176	* updated to use IEEE 802.11w/D2.0 for management frame protection
1177	  (still experimental)
1178	* fixed EAP-TTLS implementation not to crash on use of freed memory
1179	  if TLS library initialization fails
1180	* added support for EAP-TNC (Trusted Network Connect)
1181	  (this version implements the EAP-TNC method and EAP-TTLS changes
1182	  needed to run two methods in sequence (IF-T) and the IF-IMC and
1183	  IF-TNCCS interfaces from TNCC)
1184
11852006-11-24 - v0.5.6
1186	* added experimental, integrated TLSv1 client implementation with the
1187	  needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
1188	  setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
1189	  .config); this can be useful, e.g., if the target system does not
1190	  have a suitable TLS library and a minimal code size is required
1191	  (total size of this internal TLS/crypto code is bit under 50 kB on
1192	  x86 and the crypto code is shared by rest of the supplicant so some
1193	  of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
1194	* removed STAKey handshake since PeerKey handshake has replaced it in
1195	  IEEE 802.11ma and there are no known deployments of STAKey
1196	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
1197	  draft (draft-ietf-emu-eap-gpsk-01.txt)
1198	* added preliminary implementation of IEEE 802.11w/D1.0 (management
1199	  frame protection)
1200	  (Note: this requires driver support to work properly.)
1201	  (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
1202	* fixed Windows named pipes ctrl_iface to not stop listening for
1203	  commands if client program opens a named pipe and closes it
1204	  immediately without sending a command
1205	* fixed USIM PIN status determination for the case that PIN is not
1206	  needed (this allows EAP-AKA to be used with USIM cards that do not
1207	  use PIN)
1208	* added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
1209	  be used with cards that do not support file selection based on
1210	  partial AID
1211	* added support for matching the subjectAltName of the authentication
1212	  server certificate against multiple name components (e.g.,
1213	  altsubject_match="DNS:server.example.com;DNS:server2.example.com")
1214	* fixed EAP-SIM/AKA key derivation for re-authentication case (only
1215	  affects IEEE 802.1X with dynamic WEP keys)
1216	* changed ctrl_iface network configuration 'get' operations to not
1217	  return password/key material; if these fields are requested, "*"
1218	  will be returned if the password/key is set, but the value of the
1219	  parameter is not exposed
1220
12212006-08-27 - v0.5.5
1222	* added support for building Windows version with UNICODE defined
1223	  (wide-char functions)
1224	* driver_ndis: fixed static WEP configuration to avoid race condition
1225	  issues with some NDIS drivers between association and setting WEP
1226	  keys
1227	* driver_ndis: added validation for IELength value in scan results to
1228	  avoid crashes when using buggy NDIS drivers [Bug 165]
1229	* fixed Release|Win32 target in the Visual Studio project files
1230	  (previously, only Debug|Win32 target was set properly)
1231	* changed control interface API call wpa_ctrl_pending() to allow it to
1232	  return -1 on error (e.g., connection lost); control interface clients
1233	  will need to make sure that they verify that the value is indeed >0
1234	  when determining whether there are pending messages
1235	* added an alternative control interface backend for Windows targets:
1236	  Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
1237	  control interface mechanism for Windows builds (previously, UDP to
1238	  localhost was used)
1239	* changed ctrl_interface configuration for UNIX domain sockets:
1240	  - deprecated ctrl_interface_group variable (it may be removed in
1241	    future versions)
1242	  - allow both directory and group be configured with ctrl_interface
1243	    in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
1244	  - ctrl_interface=/var/run/wpa_supplicant is still supported for the
1245	    case when group is not changed
1246	* added support for controlling more than one interface per process in
1247	  Windows version
1248	* added a workaround for a case where the AP is using unknown address
1249	  (e.g., MAC address of the wired interface) as the source address for
1250	  EAPOL-Key frames; previously, that source address was used as the
1251	  destination for EAPOL-Key frames and in key derivation; now, BSSID is
1252	  used even if the source address does not match with it
1253	  (this resolves an interoperability issue with Thomson SpeedTouch 580)
1254	* added a workaround for UDP-based control interface (which was used in
1255	  Windows builds before this release) to prevent packets with forged
1256	  addresses from being accepted as local control requests
1257	* removed ndis_events.cpp and possibility of using external
1258	  ndis_events.exe; C version (ndis_events.c) is fully functional and
1259	  there is no desire to maintain two separate versions of this
1260	  implementation
1261	* ndis_events: Changed NDIS event notification design to use WMI to
1262	  learn the adapter description through Win32_PnPEntity class; this
1263	  should fix some cases where the adapter name was not recognized
1264	  correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
1265	  USB) [Bug 113]
1266	* fixed selection of the first network in ap_scan=2 mode; previously,
1267	  wpa_supplicant could get stuck in SCANNING state when only the first
1268	  network for enabled (e.g., after 'wpa_cli select_network 0')
1269	* winsvc: added support for configuring ctrl_interface parameters in
1270	  registry (ctrl_interface string value in
1271	  HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
1272	  required to enable control interface (previously, this was hardcoded
1273	  to be enabled)
1274	* allow wpa_gui subdirectory to be built with both Qt3 and Qt4
1275	* converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
1276
12772006-06-20 - v0.5.4
1278	* fixed build with CONFIG_STAKEY=y [Bug 143]
1279	* added support for doing MLME (IEEE 802.11 management frame
1280	  processing) in wpa_supplicant when using Devicescape IEEE 802.11
1281	  stack (wireless-dev.git tree)
1282	* added a new network block configuration option, fragment_size, to
1283	  configure the maximum EAP fragment size
1284	* driver_ndis: Disable WZC automatically for the selected interface to
1285	  avoid conflicts with two programs trying to control the radio; WZC
1286	  will be re-enabled (if it was enabled originally) when wpa_supplicant
1287	  is terminated
1288	* added an experimental TLSv1 client implementation
1289	  (CONFIG_TLS=internal) that can be used instead of an external TLS
1290	  library, e.g., to reduce total size requirement on systems that do
1291	  not include any TLS library by default (this is not yet complete;
1292	  basic functionality is there, but certificate validation is not yet
1293	  included)
1294	* added PeerKey handshake implementation for IEEE 802.11e
1295	  direct link setup (DLS) to replace STAKey handshake
1296	* fixed WPA PSK update through ctrl_iface for the case where the old
1297	  PSK was derived from an ASCII passphrase and the new PSK is set as
1298	  a raw PSK (hex string)
1299	* added new configuration option for identifying which network block
1300	  was used (id_str in wpa_supplicant.conf; included on
1301	  WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
1302	  variable in wpa_cli action scripts; in addition WPA_ID variable is
1303	  set to the current unique identifier that wpa_supplicant assigned
1304	  automatically for the network and that can be used with
1305	  GET_NETWORK/SET_NETWORK ctrl_iface commands)
1306	* wpa_cli action script is now called only when the connect/disconnect
1307	  status changes or when associating with a different network
1308	* fixed configuration parser not to remove CCMP from group cipher list
1309	  if WPA-None (adhoc) is used (pairwise=NONE in that case)
1310	* fixed integrated NDIS events processing not to hang the process due
1311	  to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
1312	* added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
1313	  draft-clancy-emu-eap-shared-secret-00.txt)
1314	* added Microsoft Visual Studio 2005 solution and project files for
1315	  build wpa_supplicant for Windows (see vs2005 subdirectory)
1316	* eloop_win: fixed unregistration of Windows events
1317	* l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
1318	  at the end of RSN pre-authentication and added unregistration of
1319	  a Windows event to avoid getting eloop_win stuck with an invalid
1320	  handle
1321	* driver_ndis: added support for selecting AP based on BSSID
1322	* added new environmental variable for wpa_cli action scripts:
1323	  WPA_CTRL_DIR is the current control interface directory
1324	* driver_ndis: added support for using NDISUIO instead of WinPcap for
1325	  OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
1326	  l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
1327	  wpa_supplicant without requiring WinPcap; note that using NDISUIO
1328	  requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
1329	  only one application to open the device
1330	* changed NDIS driver naming to only include device GUID, e.g.,
1331	  {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
1332	  specific \Device\NPF_ prefix before the GUID; the prefix is still
1333	  allowed for backwards compatibility, but it is not required anymore
1334	  when specifying the interface
1335	* driver_ndis: re-initialize driver interface is the adapter is removed
1336	  and re-inserted [Bug 159]
1337	* driver_madwifi: fixed TKIP and CCMP sequence number configuration on
1338	  big endian hosts [Bug 146]
1339
13402006-04-27 - v0.5.3
1341	* fixed EAP-GTC response to include correct user identity when run as
1342	  phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
1343	* driver_ndis: Fixed encryption mode configuration for unencrypted
1344	  networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
1345	  refused to associate with open networks) [Bug 106]
1346	* driver_ndis: use BSSID OID polling to detect when IBSS network is
1347	  formed even when ndis_events code is included since some NDIS drivers
1348	  do not generate media connect events in IBSS mode
1349	* config_winreg: allow global ctrl_interface parameter to be configured
1350	  in Windows registry
1351	* config_winreg: added support for saving configuration data into
1352	  Windows registry
1353	* added support for controlling network device operational state
1354	  (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
1355	  http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
1356	  that can use this information)
1357	* driver_wext: added support for WE-21 change to SSID configuration
1358	* driver_wext: fixed privacy configuration for static WEP keys mode
1359	  [Bug 140]
1360	* added an optional driver_ops callback for MLME-SETPROTECTION.request
1361	  primitive
1362	* added support for EAP-SAKE (no EAP method number allocated yet, so
1363	  this is using the same experimental type 255 as EAP-PSK)
1364	* added support for dynamically loading EAP methods (.so files) instead
1365	  of requiring them to be statically linked in; this is disabled by
1366	  default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
1367	  on how to use this)
1368
13692006-03-19 - v0.5.2
1370	* do not try to use USIM APDUs when initializing PC/SC for SIM card
1371	  access for a network that has not enabled EAP-AKA
1372	* fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
1373	  v0.5.1 due to the new support for expanded EAP types)
1374	* added support for generating EAP Expanded Nak
1375	* try to fetch scan results once before requesting new scan when
1376	  starting up in ap_scan=1 mode (this can speed up initial association
1377	  a lot with, e.g., madwifi-ng driver)
1378	* added support for receiving EAPOL frames from a Linux bridge
1379	  interface (-bbr0 on command line)
1380	* fixed EAPOL re-authentication for sessions that used PMKSA caching
1381	* changed EAP method registration to use a dynamic list of methods
1382	  instead of a static list generated at build time
1383	* fixed PMKSA cache deinitialization not to use freed memory when
1384	  removing PMKSA entries
1385	* fixed a memory leak in EAP-TTLS re-authentication
1386	* reject WPA/WPA2 message 3/4 if it does not include any valid
1387	  WPA/RSN IE
1388	* driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
1389	  if the driver does not support SIOCSIWAUTH
1390
13912006-01-29 - v0.5.1
1392	* driver_test: added better support for multiple APs and STAs by using
1393	  a directory with sockets that include MAC address for each device in
1394	  the name (driver_param=test_dir=/tmp/test)
1395	* added support for EAP expanded type (vendor specific EAP methods)
1396	* added AP_SCAN command into ctrl_iface so that ap_scan configuration
1397	  option can be changed if needed
1398	* wpa_cli/wpa_gui: skip non-socket files in control directory when
1399	  using UNIX domain sockets; this avoids selecting an incorrect
1400	  interface (e.g., a PID file could be in this directory, even though
1401	  use of this directory for something else than socket files is not
1402	  recommended)
1403	* fixed TLS library deinitialization after RSN pre-authentication not
1404	  to disable TLS library for normal authentication
1405	* driver_wext: Remove null-termination from SSID length if the driver
1406	  used it; some Linux drivers do this and they were causing problems in
1407	  wpa_supplicant not finding matching configuration block. This change
1408	  would break a case where the SSID actually ends in '\0', but that is
1409	  not likely to happen in real use.
1410	* fixed PMKSA cache processing not to trigger deauthentication if the
1411	  current PMKSA cache entry is replaced with a valid new entry
1412	* fixed PC/SC initialization for ap_scan != 1 modes (this fixes
1413	  EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
1414	  ap_scan=2)
1415
14162005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
1417	* added experimental STAKey handshake implementation for IEEE 802.11e
1418	  direct link setup (DLS); note: this is disabled by default in both
1419	  build and runtime configuration (can be enabled with CONFIG_STAKEY=y
1420	  and stakey=1)
1421	* fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
1422	  decrypt AT_ENCR_DATA attributes correctly
1423	* fixed EAP-AKA to allow resynchronization within the same session
1424	* made code closer to ANSI C89 standard to make it easier to port to
1425	  other C libraries and compilers
1426	* started moving operating system or C library specific functions into
1427	  wrapper functions defined in os.h and implemented in os_*.c to make
1428	  code more portable
1429	* wpa_supplicant can now be built with Microsoft Visual C++
1430	  (e.g., with the freely available Toolkit 2003 version or Visual
1431	  C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
1432	  example makefile for nmake
1433	* added support for using Windows registry for command line parameters
1434	  (CONFIG_MAIN=main_winsvc) and configuration data
1435	  (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
1436	  contents; this version can be run both as a Windows service and as a
1437	  normal application; 'wpasvc.exe app' to start as applicant,
1438	  'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
1439	  'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
1440	  unregister a service
1441	* made it possible to link ndis_events.exe functionality into
1442	  wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
1443	* added better support for multiple control interface backends
1444	  (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
1445	* fixed PC/SC code to use correct length for GSM AUTH command buffer
1446	  and to not use pioRecvPci with SCardTransmit() calls; these were not
1447	  causing visible problems with pcsc-lite, but Windows Winscard.dll
1448	  refused the previously used parameters; this fixes EAP-SIM and
1449	  EAP-AKA authentication using SIM/USIM card under Windows
1450	* added new event loop implementation for Windows using
1451	  WaitForMultipleObject() instead of select() in order to allow waiting
1452	  for non-socket objects; this can be selected with
1453	  CONFIG_ELOOP=eloop_win in .config
1454	* added support for selecting l2_packet implementation in .config
1455	  (CONFIG_L2_PACKET; following options are available now: linux, pcap,
1456	  winpcap, freebsd, none)
1457	* added new l2_packet implementation for WinPcap
1458	  (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
1459	  reduce latency in EAPOL receive processing from about 100 ms to about
1460	  3 ms
1461	* added support for EAP-FAST key derivation using other ciphers than
1462	  RC4-128-SHA for authentication and AES128-SHA for provisioning
1463	* added support for configuring CA certificate as DER file and as a
1464	  configuration blob
1465	* fixed private key configuration as configuration blob and added
1466	  support for using PKCS#12 as a blob
1467	* tls_gnutls: added support for using PKCS#12 files; added support for
1468	  session resumption
1469	* added support for loading trusted CA certificates from Windows
1470	  certificate store: ca_cert="cert_store://<name>", where <name> is
1471	  likely CA (Intermediate CA certificates) or ROOT (root certificates)
1472	* added C version of ndis_events.cpp and made it possible to build this
1473	  with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
1474	  easily on cross-compilation builds
1475	* added wpasvc.exe into Windows binary release; this is an alternative
1476	  version of wpa_supplicant.exe with configuration backend using
1477	  Windows registry and with the entry point designed to run as a
1478	  Windows service
1479	* integrated ndis_events.exe functionality into wpa_supplicant.exe and
1480	  wpasvc.exe and removed this additional tool from the Windows binary
1481	  release since it is not needed anymore
1482	* load winscard.dll functions dynamically when building with MinGW
1483	  since MinGW does not yet include winscard library
1484
14852005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
1486	* l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
1487	  and WinPcap to receive frames sent to PAE group address
1488	* disable EAP state machine when IEEE 802.1X authentication is not used
1489	  in order to get rid of bogus "EAP failed" messages
1490	* fixed OpenSSL error reporting to go through all pending errors to
1491	  avoid confusing reports of old errors being reported at later point
1492	  during handshake
1493	* fixed configuration file updating to not write empty variables
1494	  (e.g., proto or key_mgmt) that the file parser would not accept
1495	* fixed ADD_NETWORK ctrl_iface command to use the same default values
1496	  for variables as empty network definitions read from config file
1497	  would get
1498	* fixed EAP state machine to not discard EAP-Failure messages in many
1499	  cases (e.g., during TLS handshake)
1500	* fixed a infinite loop in private key reading if the configured file
1501	  cannot be parsed successfully
1502	* driver_madwifi: added support for madwifi-ng
1503	* wpa_gui: do not display password/PSK field contents
1504	* wpa_gui: added CA certificate configuration
1505	* driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
1506	* driver_ndis: include Beacon IEs in AssocInfo in order to notice if
1507	  the new AP is using different WPA/RSN IE
1508	* use longer timeout for IEEE 802.11 association to avoid problems with
1509	  drivers that may take more than five second to associate
1510
15112005-10-27 - v0.4.6
1512	* allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
1513	  RSN IE, but WPA IE would match with wpa_supplicant configuration
1514	* added support for named configuration blobs in order to avoid having
1515	  to use file system for external files (e.g., certificates);
1516	  variables can be set to "blob://<blob name>" instead of file path to
1517	  use a named blob; supported fields: pac_file, client_cert,
1518	  private_key
1519	* fixed RSN pre-authentication (it was broken in the clean up of WPA
1520	  state machine interface in v0.4.5)
1521	* driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
1522	  sure the driver configures broadcast decryption correctly
1523	* added ca_path (and ca_path2) configuration variables that can be used
1524	  to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
1525	  system-wide trusted CA list
1526	* added support for starting wpa_supplicant without a configuration
1527	  file (-C argument must be used to set ctrl_interface parameter for
1528	  this case; in addition, -p argument can be used to provide
1529	  driver_param; these new arguments can also be used with a
1530	  configuration to override the values from the configuration)
1531	* added global control interface that can be optionally used for adding
1532	  and removing network interfaces dynamically (-g command line argument
1533	  for both wpa_supplicant and wpa_cli) without having to restart
1534	  wpa_supplicant process
1535	* wpa_gui:
1536	  - try to save configuration whenever something is modified
1537	  - added WEP key configuration
1538	  - added possibility to edit the current network configuration
1539	* driver_ndis: fixed driver polling not to increase frequency on each
1540	  received EAPOL frame due to incorrectly cancelled timeout
1541	* added simple configuration file examples (in examples subdirectory)
1542	* fixed driver_wext.c to filter wireless events based on ifindex to
1543	  avoid interfaces receiving events from other interfaces
1544	* delay sending initial EAPOL-Start couple of seconds to speed up
1545	  authentication for the most common case of Authenticator starting
1546	  EAP authentication immediately after association
1547
15482005-09-25 - v0.4.5
1549	* added a workaround for clearing keys with ndiswrapper to allow
1550	  roaming from WPA enabled AP to plaintext one
1551	* added docbook documentation (doc/docbook) that can be used to
1552	  generate, e.g., man pages
1553	* l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
1554	  PF_PACKET in order to prepare for network devices that do not use
1555	  Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
1556	* use receipt of EAPOL-Key frame as a lower layer success indication
1557	  for EAP state machine to allow recovery from dropped EAP-Success
1558	  frame
1559	* cleaned up internal EAPOL frame processing by not including link
1560	  layer (Ethernet) header during WPA and EAPOL/EAP processing; this
1561	  header is added only when transmitted the frame; this makes it easier
1562	  to use wpa_supplicant on link layers that use different header than
1563	  Ethernet
1564	* updated EAP-PSK to use draft 9 by default since this can now be
1565	  tested with hostapd; removed support for draft 3, including
1566	  server_nai configuration option from network blocks
1567	* driver_wired: add PAE address to the multicast address list in order
1568	  to be able to receive EAPOL frames with drivers that do not include
1569	  these multicast addresses by default
1570	* driver_wext: add support for WE-19
1571	* added support for multiple configuration backends (CONFIG_BACKEND
1572	  option); currently, only 'file' is supported (i.e., the format used
1573	  in wpa_supplicant.conf)
1574	* added support for updating configuration ('wpa_cli save_config');
1575	  this is disabled by default and can be enabled with global
1576	  update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
1577	  and wpa_gui to store the configuration changes in a permanent store
1578	* added GET_NETWORK ctrl_iface command
1579	  (e.g., 'wpa_cli get_network 0 ssid')
1580
15812005-08-21 - v0.4.4
1582	* replaced OpenSSL patch for EAP-FAST support
1583	  (openssl-tls-extensions.patch) with a more generic and correct
1584	  patch (the new patch is not compatible with the previous one, so the
1585	  OpenSSL library will need to be patched with the new patch in order
1586	  to be able to build wpa_supplicant with EAP-FAST support)
1587	* added support for using Windows certificate store (through CryptoAPI)
1588	  for client certificate and private key operations (EAP-TLS)
1589	  (see wpa_supplicant.conf for more information on how to configure
1590	  this with private_key)
1591	* ported wpa_gui to Windows
1592	* added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
1593	  built with the open source version of the Qt4 for Windows
1594	* allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
1595	  with drivers that do not support WPA
1596	* ndis_events: fixed Windows 2000 support
1597	* added support for enabling/disabling networks from the list of all
1598	  configured networks ('wpa_cli enable_network <network id>' and
1599	  'wpa_cli disable_network <network id>')
1600	* added support for adding and removing network from the current
1601	  configuration ('wpa_cli add_network' and 'wpa_cli remove_network
1602	  <network id>'); added networks are disabled by default and they can
1603	  be enabled with enable_network command once the configuration is done
1604	  for the new network; note: configuration file is not yet updated, so
1605	  these new networks are lost when wpa_supplicant is restarted
1606	* added support for setting network configuration parameters through
1607	  the control interface, for example:
1608	  wpa_cli set_network 0 ssid "\"my network\""
1609	* fixed parsing of strings that include both " and # within double
1610	  quoted area (e.g., "start"#end")
1611	* added EAP workaround for PEAP session resumption: allow outer,
1612	  i.e., not tunneled, EAP-Success to terminate session since; this can
1613	  be disabled with eap_workaround=0
1614	  (this was allowed for PEAPv1 before, but now it is also allowed for
1615	  PEAPv0 since at least one RADIUS authentication server seems to be
1616	  doing this for PEAPv0, too)
1617	* wpa_gui: added preliminary support for adding new networks to the
1618	  wpa_supplicant configuration (double click on the scan results to
1619	  open network configuration)
1620
16212005-06-26 - v0.4.3
1622	* removed interface for external EAPOL/EAP supplicant (e.g.,
1623	  Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
1624	  anymore and is unlikely to be used by anyone
1625	* driver_ndis: fixed WinPcap 3.0 support
1626	* fixed build with CONFIG_DNET_PCAP=y on Linux
1627	* l2_packet: moved different implementations into separate files
1628	  (l2_packet_*.c)
1629
16302005-06-12 - v0.4.2
1631	* driver_ipw: updated driver structures to match with ipw2200-1.0.4
1632	  (note: ipw2100-1.1.0 is likely to require an update to work with
1633	  this)
1634	* added support for using ap_scan=2 mode with multiple network blocks;
1635	  wpa_supplicant will go through the networks one by one until the
1636	  driver reports a successful association; this uses the same order for
1637	  networks as scan_ssid=1 scans, i.e., the priority field is ignored
1638	  and the network block order in the file is used instead
1639	* fixed a potential issue in RSN pre-authentication ending up using
1640	  freed memory if pre-authentication times out
1641	* added support for matching alternative subject name extensions of the
1642	  authentication server certificate; new configuration variables
1643	  altsubject_match and altsubject_match2
1644	* driver_ndis: added support for IEEE 802.1X authentication with wired
1645	  NDIS drivers
1646	* added support for querying private key password (EAP-TLS) through the
1647	  control interface (wpa_cli/wpa_gui) if one is not included in the
1648	  configuration file
1649	* driver_broadcom: fixed couple of memory leaks in scan result
1650	  processing
1651	* EAP-PAX is now registered as EAP type 46
1652	* fixed EAP-PAX MAC calculation
1653	* fixed EAP-PAX CK and ICK key derivation
1654	* added support for using password with EAP-PAX (as an alternative to
1655	  entering key with eappsk); SHA-1 hash of the password will be used as
1656	  the key in this case
1657	* added support for arbitrary driver interface parameters through the
1658	  configuration file with a new driver_param field; this adds a new
1659	  driver_ops function set_param()
1660	* added possibility to override l2_packet module with driver interface
1661	  API (new send_eapol handler); this can be used to implement driver
1662	  specific TX/RX functions for EAPOL frames
1663	* fixed ctrl_interface_group processing for the case where gid is
1664	  entered as a number, not group name
1665	* driver_test: added support for testing hostapd with wpa_supplicant
1666	  by using test driver interface without any kernel drivers or network
1667	  cards
1668
16692005-05-22 - v0.4.1
1670	* driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
1671	  packets to be encrypted; this was apparently broken by the changed
1672	  ioctl order in v0.4.0
1673	* driver_madwifi: added preliminary support for compiling against 'BSD'
1674	  branch of madwifi CVS tree
1675	* added support for EAP-MSCHAPv2 password retries within the same EAP
1676	  authentication session
1677	* added support for password changes with EAP-MSCHAPv2 (used when the
1678	  password has expired)
1679	* added support for reading additional certificates from PKCS#12 files
1680	  and adding them to the certificate chain
1681	* fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
1682	  were used
1683	* fixed a possible double free in EAP-TTLS fast-reauthentication when
1684	  identity or password is entered through control interface
1685	* display EAP Notification messages to user through control interface
1686	  with "CTRL-EVENT-EAP-NOTIFICATION" prefix
1687	* added GUI version of wpa_cli, wpa_gui; this is not build
1688	  automatically with 'make'; use 'make wpa_gui' to build (this requires
1689	  Qt development tools)
1690	* added 'disconnect' command to control interface for setting
1691	  wpa_supplicant in state where it will not associate before
1692	  'reassociate' command has been used
1693	* added support for selecting a network from the list of all configured
1694	  networks ('wpa_cli select_network <network id>'; this disabled all
1695	  other networks; to re-enable, 'wpa_cli select_network any')
1696	* added support for getting scan results through control interface
1697	* added EAP workaround for PEAPv1 session resumption: allow outer,
1698	  i.e., not tunneled, EAP-Success to terminate session since; this can
1699	  be disabled with eap_workaround=0
1700
17012005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
1702	* added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
1703	  used to reduce the size of the wpa_supplicant considerably if
1704	  debugging code is not needed
1705	* fixed EAPOL-Key validation to drop packets with invalid Key Data
1706	  Length; such frames could have crashed wpa_supplicant due to buffer
1707	  overflow
1708	* added support for wired authentication (IEEE 802.1X on wired
1709	  Ethernet); driver interface 'wired'
1710	* obsoleted set_wpa() handler in the driver interface API (it can be
1711	  replaced by moving enable/disable functionality into init()/deinit())
1712	  (calls to set_wpa() are still present for backwards compatibility,
1713	  but they may be removed in the future)
1714	* driver_madwifi: fixed association in plaintext mode
1715	* modified the EAP workaround that accepts EAP-Success with incorrect
1716	  Identifier to be even less strict about verification in order to
1717	  interoperate with some authentication servers
1718	* added support for sending TLS alerts
1719	* added support for 'any' SSID wildcard; if ssid is not configured or
1720	  is set to an empty string, any SSID will be accepted for non-WPA AP
1721	* added support for asking PIN (for SIM) from frontends (e.g.,
1722	  wpa_cli); if a PIN is needed, but not included in the configuration
1723	  file, a control interface request is sent and EAP processing is
1724	  delayed until the PIN is available
1725	* added support for using external devices (e.g., a smartcard) for
1726	  private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
1727	  new wpa_supplicant.conf variables:
1728	  - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
1729	  - network: engine, engine_id, key_id
1730	* added experimental support for EAP-PAX
1731	* added monitor mode for wpa_cli (-a<path to a program to run>) that
1732	  allows external commands (e.g., shell scripts) to be run based on
1733	  wpa_supplicant events, e.g., when authentication has been completed
1734	  and data connection is ready; other related wpa_cli arguments:
1735	  -B (run in background), -P (write PID file); wpa_supplicant has a new
1736	  command line argument (-W) that can be used to make it wait until a
1737	  control interface command is received in order to avoid missing
1738	  events
1739	* added support for opportunistic WPA2 PMKSA key caching (disabled by
1740	  default, can be enabled with proactive_key_caching=1)
1741	* fixed RSN IE in 4-Way Handshake message 2/4 for the case where
1742	  Authenticator rejects PMKSA caching attempt and the driver is not
1743	  using assoc_info events
1744	* added -P<pid file> argument for wpa_supplicant to write the current
1745	  process id into a file
1746
17472005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
1748	* added new phase1 option parameter, include_tls_length=1, to force
1749	  wpa_supplicant to add TLS Message Length field to all TLS messages
1750	  even if the packet is not fragmented; this may be needed with some
1751	  authentication servers
1752	* fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
1753	  using drivers that take care of AP selection (e.g., when using
1754	  ap_scan=2)
1755	* fixed reprocessing of pending request after ctrl_iface requests for
1756	  identity/password/otp
1757	* fixed ctrl_iface requests for identity/password/otp in Phase 2 of
1758	  EAP-PEAP and EAP-TTLS
1759	* all drivers using driver_wext: set interface up and select Managed
1760	  mode when starting wpa_supplicant; set interface down when exiting
1761	* renamed driver_ipw2100.c to driver_ipw.c since it now supports both
1762	  ipw2100 and ipw2200; please note that this also changed the
1763	  configuration variable in .config to CONFIG_DRIVER_IPW
1764
17652005-01-24 - v0.3.6
1766	* fixed a busy loop introduced in v0.3.5 for scan result processing
1767	  when no matching AP is found
1768
17692005-01-23 - v0.3.5
1770	* added a workaround for an interoperability issue with a Cisco AP
1771	  when using WPA2-PSK
1772	* fixed non-WPA IEEE 802.1X to use the same authentication timeout as
1773	  WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
1774	  retransmission of dropped frames)
1775	* fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
1776	  (e.g., segfault when processing EAPOL-Key frames)
1777	* fixed EAP workaround and fast reauthentication configuration for
1778	  RSN pre-authentication; previously these were disabled and
1779	  pre-authentication would fail if the used authentication server
1780	  requires EAP workarounds
1781	* added support for blacklisting APs that fail or timeout
1782	  authentication in ap_scan=1 mode so that all APs are tried in cases
1783	  where the ones with strongest signal level are failing authentication
1784	* fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
1785	  authentication attempt
1786	* allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
1787	  in the previous authentication (previously, only Phase 1 success was
1788	  verified)
1789
17902005-01-09 - v0.3.4
1791	* added preliminary support for IBSS (ad-hoc) mode configuration
1792	  (mode=1 in network block); this included a new key_mgmt mode
1793	  WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
1794	  key management; see wpa_supplicant.conf for more details and an
1795	  example on how to configure this (note: this is currently implemented
1796	  only for driver_hostapd.c, but the changes should be trivial to add
1797	  in associate() handler for other drivers, too (assuming the driver
1798	  supports WPA-None)
1799	* added preliminary port for native Windows (i.e., no cygwin) using
1800	  mingw
1801
18022005-01-02 - v0.3.3
1803	* added optional support for GNU Readline and History Libraries for
1804	  wpa_cli (CONFIG_READLINE)
1805	* cleaned up EAP state machine <-> method interface and number of
1806	  small problems with error case processing not terminating on
1807	  EAP-Failure but waiting for timeout
1808	* added couple of workarounds for interoperability issues with a
1809	  Cisco AP when using WPA2
1810	* added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
1811	  Note: This requires a patch for openssl to add support for TLS
1812	  extensions and number of workarounds for operations without
1813	  certificates. Proof of concept type of experimental patch is
1814	  included in openssl-tls-extensions.patch.
1815
18162004-12-19 - v0.3.2
1817	* fixed private key loading for cases where passphrase is not set
1818	* fixed Windows/cygwin L2 packet handler freeing; previous version
1819	  could cause a segfault when RSN pre-authentication was completed
1820	* added support for PMKSA caching with drivers that generate RSN IEs
1821	  (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
1822	  but similar code can be easily added to driver_ndiswrapper.c once
1823	  ndiswrapper gets full support for RSN PMKSA caching
1824	* improved recovery from PMKID mismatches by requesting full EAP
1825	  authentication in case of failed PMKSA caching attempt
1826	* driver_ndis: added support for NDIS NdisMIncidateStatus() events
1827	  (this requires that ndis_events is ran while wpa_supplicant is
1828	  running)
1829	* driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
1830	* added support for driver interfaces to replace the interface name
1831	  based on driver/OS specific mapping, e.g., in case of driver_ndis,
1832	  this allows the beginning of the adapter description to be used as
1833	  the interface name
1834	* added support for CR+LF (Windows-style) line ends in configuration
1835	  file
1836	* driver_ndis: enable radio before starting scanning, disable radio
1837	  when exiting
1838	* modified association event handler to set portEnabled = FALSE before
1839	  clearing port Valid in order to reset EAP state machine and avoid
1840	  problems with new authentication getting ignored because of state
1841	  machines ending up in AUTHENTICATED/SUCCESS state based on old
1842	  information
1843	* added support for driver events to add PMKID candidates in order to
1844	  allow drivers to give priority to most likely roaming candidates
1845	* driver_hostap: moved PrivacyInvoked configuration to associate()
1846	  function so that this will not be set for plaintext connections
1847	* added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
1848	  interface can distinguish plaintext and IEEE 802.1X (no WPA)
1849	  authentication
1850	* fixed static WEP key configuration to use broadcast/default type for
1851	  all keys (previously, the default TX key was configured as pairwise/
1852	  unicast key)
1853	* driver_ndis: added legacy WPA capability detection for non-WPA2
1854	  drivers
1855	* added support for setting static WEP keys for IEEE 802.1X without
1856	  dynamic WEP keying (eapol_flags=0)
1857
18582004-12-12 - v0.3.1
1859	* added support for reading PKCS#12 (PFX) files (as a replacement for
1860	  PEM/DER) to get certificate and private key (CONFIG_PKCS12)
1861	* fixed compilation with CONFIG_PCSC=y
1862	* added new ap_scan mode, ap_scan=2, for drivers that take care of
1863	  association, but need to be configured with security policy and SSID,
1864	  e.g., ndiswrapper and NDIS driver; this mode should allow such
1865	  drivers to work with hidden SSIDs and optimized roaming; when
1866	  ap_scan=2 is used, only the first network block in the configuration
1867	  file is used and this configuration should have explicit security
1868	  policy (i.e., only one option in the lists) for key_mgmt, pairwise,
1869	  group, proto variables
1870	* added experimental port of wpa_supplicant for Windows
1871	  - driver_ndis.c driver interface (NDIS OIDs)
1872	  - currently, this requires cygwin and WinPcap
1873	  - small utility, win_if_list, can be used to get interface name
1874	* control interface can now be removed at build time; add
1875	  CONFIG_CTRL_IFACE=y to .config to maintain old functionality
1876	* optional Xsupplicant interface can now be removed at build time;
1877	  (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
1878	* added auth_alg to driver interface associate() parameters to make it
1879	  easier for drivers to configure authentication algorithm as part of
1880	  the association
1881
18822004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
1883	* driver_broadcom: added new driver interface for Broadcom wl.o driver
1884	  (a generic driver for Broadcom IEEE 802.11a/g cards)
1885	* wpa_cli: fixed parsing of -p <path> command line argument
1886	* PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
1887	  ACK, not tunneled EAP-Success (of which only the first byte was
1888	  actually send due to a bug in previous code); this seems to
1889	  interoperate with most RADIUS servers that implements PEAPv1
1890	* PEAPv1: added support for terminating PEAP authentication on tunneled
1891	  EAP-Success message; this can be configured by adding
1892	  peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
1893	  (some RADIUS servers require this whereas others require a tunneled
1894	  reply
1895	* PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
1896	  the old label for key derivation; previously, the default was 1,
1897	  but it looks like most existing PEAPv1 implementations use the old
1898	  label which is thus more suitable default option
1899	* added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
1900	* fixed parsing of wep_tx_keyidx
1901	* added support for configuring list of allowed Phase 2 EAP types
1902	  (for both EAP-PEAP and EAP-TTLS) instead of only one type
1903	* added support for configuring IEEE 802.11 authentication algorithm
1904	  (auth_alg; mainly for using Shared Key authentication with static
1905	  WEP keys)
1906	* added support for EAP-AKA (with UMTS SIM)
1907	* fixed couple of errors in PCSC handling that could have caused
1908	  random-looking errors for EAP-SIM
1909	* added support for EAP-SIM pseudonyms and fast re-authentication
1910	* added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
1911	  session resumption)
1912	* added support for EAP-SIM with two challanges
1913	  (phase1="sim_min_num_chal=3" can be used to require three challenges)
1914	* added support for configuring DH/DSA parameters for an ephemeral DH
1915	  key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
1916	  dh_file and dh_file2 (phase 2); this adds support for using DSA keys
1917	  and optional DH key exchange to achieve forward secracy with RSA keys
1918	* added support for matching subject of the authentication server
1919	  certificate with a substring when using EAP-TLS/PEAP/TTLS; new
1920	  configuration variables subject_match and subject_match2
1921	* changed SSID configuration in driver_wext.c (used by many driver
1922	  interfaces) to use ssid_len+1 as the length for SSID since some Linux
1923	  drivers expect this
1924	* fixed couple of unaligned reads in scan result parsing to fix WPA
1925	  connection on some platforms (e.g., ARM)
1926	* added driver interface for Intel ipw2100 driver
1927	* added support for LEAP with WPA
1928	* added support for larger scan results report (old limit was 4 kB of
1929	  data, i.e., about 35 or so APs) when using Linux wireless extensions
1930	  v17 or newer
1931	* fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
1932	  only if there is a PMKSA cache entry for the current AP
1933	* fixed error handling for case where reading of scan results fails:
1934	  must schedule a new scan or wpa_supplicant will remain waiting
1935	  forever
1936	* changed debug output to remove shared password/key material by
1937	  default; all key information can be included with -K command line
1938	  argument to match the previous behavior
1939	* added support for timestamping debug log messages (disabled by
1940	  default, can be enabled with -t command line argument)
1941	* set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
1942	  if keys are not configured to be used; this fixes IEEE 802.1X mode
1943	  with drivers that use this information to configure whether Privacy
1944	  bit can be in Beacon frames (e.g., ndiswrapper)
1945	* avoid clearing driver keys if no keys have been configured since last
1946	  key clear request; this seems to improve reliability of group key
1947	  handshake for ndiswrapper & NDIS driver which seems to be suffering
1948	  of some kind of timing issue when the keys are cleared again after
1949	  association
1950	* changed driver interface API:
1951	  - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
1952	    version is being used (now, this is set to 2; previously, it was
1953	    not defined)
1954	  - pass pointer to private data structure to all calls
1955	  - the new API is not backwards compatible; all in-tree driver
1956	    interfaces has been converted to the new API
1957	* added support for controlling multiple interfaces (radios) per
1958	  wpa_supplicant process; each interface needs to be listed on the
1959	  command line (-c, -i, -D arguments) with -N as a separator
1960	  (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
1961	* added a workaround for EAP servers that incorrectly use same Id for
1962	  sequential EAP packets
1963	* changed libpcap/libdnet configuration to use .config variable,
1964	  CONFIG_DNET_PCAP, instead of requiring Makefile modification
1965	* improved downgrade attack detection in IE verification of msg 3/4:
1966	  verify both WPA and RSN IEs, if present, not only the selected one;
1967	  reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
1968	  Probe Response frame, and RSN is enabled in wpa_supplicant
1969	  configuration
1970	* fixed WPA msg 3/4 processing to allow Key Data field contain other
1971	  IEs than just one WPA IE
1972	* added support for FreeBSD and driver interface for the BSD net80211
1973	  layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
1974	  required kernel mods have not yet been committed
1975	* made EAP workarounds configurable; enabled by default, can be
1976	  disabled with network block option eap_workaround=0
1977
19782004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
1979	* resolved couple of interoperability issues with EAP-PEAPv1 and
1980	  Phase 2 (inner EAP) fragment reassembly
1981	* driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
1982	  AP is using non-zero key index for the unicast key and key index zero
1983	  for the broadcast key
1984	* driver_hostap: fixed IEEE 802.1X WEP key updates and
1985	  re-authentication by allowing unencrypted EAPOL frames when not using
1986	  WPA
1987	* added a new driver interface, 'wext', which uses only standard,
1988	  driver independent functionality in Linux wireless extensions;
1989	  currently, this can be used only for non-WPA IEEE 802.1X mode, but
1990	  eventually, this is to be extended to support full WPA/WPA2 once
1991	  Linux wireless extensions get support for this
1992	* added support for mode in which the driver is responsible for AP
1993	  scanning and selection; this is disabled by default and can be
1994	  enabled with global ap_scan=0 variable in wpa_supplicant.conf;
1995	  this mode can be used, e.g., with generic 'wext' driver interface to
1996	  use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
1997	  supporting wireless extensions.
1998	* driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
1999	  operation with an AP that does not include SSID in the Beacon frames)
2000	* added support for new EAP authentication methods:
2001	  EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
2002	* added support for asking one-time-passwords from frontends (e.g.,
2003	  wpa_cli); this 'otp' command works otherwise like 'password' command,
2004	  but the password is used only once and the frontend will be asked for
2005	  a new password whenever a request from authenticator requires a
2006	  password; this can be used with both EAP-OTP and EAP-GTC
2007	* changed wpa_cli to automatically re-establish connection so that it
2008	  does not need to be re-started when wpa_supplicant is terminated and
2009	  started again
2010	* improved user data (identity/password/otp) requests through
2011	  frontends: process pending EAPOL packets after getting new
2012	  information so that full authentication does not need to be
2013	  restarted; in addition, send pending requests again whenever a new
2014	  frontend is attached
2015	* changed control frontends to use a new directory for socket files to
2016	  make it easier for wpa_cli to automatically select between interfaces
2017	  and to provide access control for the control interface;
2018	  wpa_supplicant.conf: ctrl_interface is now a path
2019	  (/var/run/wpa_supplicant is the recommended path) and
2020	  ctrl_interface_group can be used to select which group gets access to
2021	  the control interface;
2022	  wpa_cli: by default, try to connect to the first interface available
2023	  in /var/run/wpa_supplicant; this path can be overriden with -p option
2024	  and an interface can be selected with -i option (i.e., in most common
2025	  cases, wpa_cli does not need to get any arguments)
2026	* added support for LEAP
2027	* added driver interface for Linux ndiswrapper
2028	* added priority option for network blocks in the configuration file;
2029	  this allows networks to be grouped based on priority (the scan
2030	  results are searched for matches with network blocks in this order)
2031
20322004-06-20 - v0.2.3
2033	* sort scan results to improve AP selection
2034	* fixed control interface socket removal for some error cases
2035	* improved scan requesting and authentication timeout
2036	* small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
2037	  TLS processing
2038	* PEAP version can now be forced with phase1="peapver=<ver>"
2039	  (mostly for testing; by default, the highest version supported by
2040	  both the Supplicant and Authentication Server is selected
2041	  automatically)
2042	* added support for madwifi driver (Atheros ar521x)
2043	* added a workaround for cases where AP sets Install Tx/Rx bit for
2044	  WPA Group Key messages when pairwise keys are used (without this,
2045	  the Group Key would be used for Tx and the AP would drop frames
2046	  from the station)
2047	* added GSM SIM/USIM interface for GSM authentication algorithm for
2048	  EAP-SIM; this requires pcsc-lite
2049	* added support for ATMEL AT76C5XXx driver
2050	* fixed IEEE 802.1X WEP key derivation in the case where Authenticator
2051	  does not include key data in the EAPOL-Key frame (i.e., part of
2052	  EAP keying material is used as data encryption key)
2053	* added support for using plaintext and static WEP networks
2054	  (key_mgmt=NONE)
2055
20562004-05-31 - v0.2.2
2057	* added support for new EAP authentication methods:
2058	  EAP-TTLS/EAP-MD5-Challenge
2059	  EAP-TTLS/EAP-GTC
2060	  EAP-TTLS/EAP-MSCHAPv2
2061	  EAP-TTLS/EAP-TLS
2062	  EAP-TTLS/MSCHAPv2
2063	  EAP-TTLS/MSCHAP
2064	  EAP-TTLS/PAP
2065	  EAP-TTLS/CHAP
2066	  EAP-PEAP/TLS
2067	  EAP-PEAP/GTC
2068	  EAP-PEAP/MD5-Challenge
2069	  EAP-GTC
2070	  EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
2071	* added support for anonymous identity (to be used when identity is
2072	  sent in plaintext; real identity will be used within TLS protected
2073	  tunnel (e.g., with EAP-TTLS)
2074	* added event messages from wpa_supplicant to frontends, e.g., wpa_cli
2075	* added support for requesting identity and password information using
2076	  control interface; in other words, the password for EAP-PEAP or
2077	  EAP-TTLS does not need to be included in the configuration file since
2078	  a frontand (e.g., wpa_cli) can ask it from the user
2079	* improved RSN pre-authentication to use a candidate list and process
2080	  all candidates from each scan; not only one per scan
2081	* fixed RSN IE and WPA IE capabilities field parsing
2082	* ignore Tx bit in GTK IE when Pairwise keys are used
2083	* avoid making new scan requests during IEEE 802.1X negotiation
2084	* use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
2085	  with TLS support (this replaces the included implementation with
2086	  library code to save about 8 kB since the library code is needed
2087	  anyway for TLS)
2088	* fixed WPA-PSK only mode when compiled without IEEE 802.1X support
2089	  (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
2090
20912004-05-06 - v0.2.1
2092	* added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
2093	  Supplicant
2094	  - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
2095	  - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
2096	  - EAP-MD5 (cannot be used with WPA-RADIUS)
2097	    [draft-ietf-eap-rfc2284bis-09.txt]
2098	  - EAP-TLS [RFC 2716]
2099	  - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
2100	  - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
2101	    [draft-kamath-pppext-eap-mschapv2-00.txt]
2102	    (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
2103	    default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
2104	  - new configuration file options: eap, identity, password, ca_cert,
2105	    client_cert, privatekey, private_key_passwd
2106	  - Xsupplicant is not required anymore, but it can be used by
2107	    disabling the internal IEEE 802.1X Supplicant with -e command line
2108	    option
2109	  - this code is not included in the default build; Makefile need to
2110	    be edited for this (uncomment lines for selected functionality)
2111	  - EAP-TLS and EAP-PEAP require openssl libraries
2112	* use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
2113	* added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
2114	  (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
2115	   EAPOL-Key frames instead of WPA key handshakes)
2116	* added support for IEEE 802.11i/RSN (WPA2)
2117	  - improved PTK Key Handshake
2118	  - PMKSA caching, pre-authentication
2119	* fixed wpa_supplicant to ignore possible extra data after WPA
2120	  EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
2121	  TPTK' error from message 3 of 4-Way Handshake in case the AP
2122	  includes extra data after the EAPOL-Key)
2123	* added interface for external programs (frontends) to control
2124	  wpa_supplicant
2125	  - CLI example (wpa_cli) with interactive mode and command line
2126	    mode
2127	  - replaced SIGUSR1 status/statistics with the new control interface
2128	* made some feature compile time configurable
2129	  - .config file for make
2130	  - driver interfaces (hostap, hermes, ..)
2131	  - EAPOL/EAP functions
2132
21332004-02-15 - v0.2.0
2134	* Initial version of wpa_supplicant
