879	* wpa_cli: added optional support for controlling wpa_supplicant
880	  remotely over UDP (CONFIG_CTRL_IFACE=udp-remote) for testing purposes
881	* wpa_cli: extended tab completion to more commands
882	* changed SSID output to use printf-escaped strings instead of masking
883	  of non-ASCII characters

934	  compressed domain name format and support multiple Bonjour PTR matches
935	  for the same key
936	* use deauthentication instead of disassociation for all disconnection
937	  operations; this removes the now unused disassociate() wpa_driver_ops
938	  callback
939	* optimized PSK generation on P2P GO by caching results to avoid
940	  multiple PBKDF2 operations
941	* added okc=1 global configuration parameter to allow OKC to be enabled
942	  by default for all network blocks
943	* added a workaround for WPS PBC session overlap detection to avoid
944	  interop issues with deployed station implementations that do not
945	  remove active PBC indication from Probe Request frames properly
946	* added basic support for 60 GHz band
947	* extend EAPOL frames processing workaround for roaming cases
948	  (postpone processing of unexpected EAPOL frame until association
949	  event to handle reordered events)
950
9512012-05-10 - v1.0
952	* bsd: Add support for setting HT values in IFM_MMASK.
953	* Delay STA entry removal until Deauth/Disassoc TX status in AP mode.
954	  This allows the driver to use PS buffering of Deauthentication and
955	  Disassociation frames when the STA is in power save sleep. Only
956	  available with drivers that provide TX status events for Deauth/
957	  Disassoc frames (nl80211).
958	* Drop oldest unknown BSS table entries first. This makes it less
959	  likely to hit connection issues in environments with huge number
960	  of visible APs.
961	* Add systemd support.
962	* Add support for setting the syslog facility from the config file
963	  at build time.
964	* atheros: Add support for IEEE 802.11w configuration.
965	* AP mode: Allow enable HT20 if driver supports it, by setting the
966	  config parameter ieee80211n.
967	* Allow AP mode to disconnect STAs based on low ACK condition (when
968	  the data connection is not working properly, e.g., due to the STA
969	  going outside the range of the AP). Disabled by default, enable by
970	  config option disassoc_low_ack.
971	* nl80211:
972	  - Support GTK rekey offload.
973	  - Support PMKSA candidate events. This adds support for RSN
974	    pre-authentication with nl80211 interface and drivers that handle
975	    roaming internally.

977	  - Add a DBus signal for EAP SM requests, emitted on the Interface
978	    object.
979	  - Export max scan ssids supported by the driver as MaxScanSSID.
980	  - Add signal Certification for information about server certification.
981	  - Add BSSExpireAge and BSSExpireCount interface properties and

985	  - Add Interface.Country property and support to get/set the value.
986	  - Add DBus property CurrentAuthMode.
987	  - P2P DBus API added.
988	  - Emit property changed events (for property BSSs) when adding/
989	    removing BSSs.
990	  - Treat '' in SSIDs of Interface.Scan as a request for broadcast
991	    scan, instead of ignoring it.
992	  - Add DBus getter/setter for FastReauth.
993	  - Raise PropertiesChanged on org.freedesktop.DBus.Properties.
994	* wpa_cli:
995	  - Send AP-STA-DISCONNECTED event when an AP disconnects a station
996	    due to inactivity.
997	  - Make second argument to set command optional. This can be used to
998	    indicate a zero length value.
999	  - Add signal_poll command.
1000	  - Add bss_expire_age and bss_expire_count commands to set/get BSS
1001	    cache expiration age and expiration scan count.
1002	  - Add ability to set scan interval (the time in seconds wpa_s waits
1003	    before requesting a new scan after failing to find a suitable
1004	    network in scan results) using scan_interval command.
1005	  - Add event CTRL-EVENT-ASSOC-REJECT for association rejected.
1006	  - Add command get version, that returns wpa_supplicant version string.
1007	  - Add command sta_autoconnect for disabling automatic reconnection
1008	    on receiving disconnection event.
1009	  - Setting bssid parameter to an empty string "" or any can now be
1010	    used to clear the bssid_set flag in a network block, i.e., to remove
1011	    bssid filtering.
1012	  - Add tdls_testing command to add a special testing feature for
1013	    changing TDLS behavior. Build param CONFIG_TDLS_TESTING must be
1014	    enabled as well.
1015	  - For interworking, add wpa_cli commands interworking_select,
1016	    interworking_connect, anqp_get, fetch_anqp, and stop_fetch_anqp.
1017	  - Many P2P commands were added. See README-P2P.
1018	  - Many WPS/WPS ER commands - see WPS/WPS ER sections for details.
1019	  - Allow set command to change global config parameters.
1020	  - Add log_level command, which can be used to display the current

1022	  - Add note command, which can be used to insert notes to the debug
1023	    log.
1024	  - Add internal line edit implementation. CONFIG_WPA_CLI_EDIT=y
1025	    can now be used to build wpa_cli with internal implementation of
1026	    line editing and history support. This can be used as a replacement
1027	    for CONFIG_READLINE=y.
1028	* AP mode: Add max_num_sta config option, which can be used to limit
1029	  the number of stations allowed to connect to the AP.
1030	* Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad
1031	  config file.
1032	* wext: Increase scan timeout from 5 to 10 seconds.
1033	* Add blacklist command, allowing an external program to
1034	  manage the BSS blacklist and display its current contents.
1035	* WPS:
1036	  - Add wpa_cli wps_pin get command for generating random PINs. This can
1037	    be used in a UI to generate a PIN without starting WPS (or P2P)
1038	    operation.
1039	  - Set RF bands based on driver capabilities, instead of hardcoding
1040	    them.
1041	  - Add mechanism for indicating non-standard WPS errors.

1043	    by default.
1044	  - Add wps_ap_pin cli command for wpa_supplicant AP mode.
1045	  - Add wps_check_pin cli command for processing PIN from user input.
1046	    UIs can use this command to process a PIN entered by a user and to
1047	    validate the checksum digit (if present).
1048	  - Cancel WPS operation on PBC session overlap detection.
1049	  - New wps_cancel command in wpa_cli will cancel a pending WPS
1050	    operation.
1051	  - wpa_cli action: Add WPS_EVENT_SUCCESS and WPS_EVENT_FAIL handlers.
1052	  - Trigger WPS config update on Manufacturer, Model Name, Model
1053	    Number, and Serial Number changes.
1054	  - Fragment size is now configurable for EAP-WSC peer. Use
1055	    wpa_cli set wps_fragment_size <val>.
1056	  - Disable AP PIN after 10 consecutive failures. Slow down attacks on
1057	    failures up to 10.
1058	  - Allow AP to start in Enrollee mode without AP PIN for probing, to
1059	    be compatible with Windows 7.
1060	  - Add Config Error into WPS-FAIL events to provide more info to the
1061	    user on how to resolve the issue.
1062	  - Label and Display config methods are not allowed to be enabled
1063	    at the same time, since it is unclear which PIN to use if both
1064	    methods are advertised.
1065	  - When controlling multiple interfaces:
1066	     - apply WPS commands to all interfaces configured to use WPS
1067	     - apply WPS config changes to all interfaces that use WPS
1068	     - when an attack is detected on any interface, disable AP PIN on
1069	       all interfaces
1070	* WPS ER:
1071	  - Add special AP Setup Locked mode to allow read only ER.
1072	    ap_setup_locked=2 can now be used to enable a special mode where
1073	    WPS ER can learn the current AP settings, but cannot change them.
1074	  - Show SetSelectedRegistrar events as ctrl_iface events
1075	  - Add wps_er_set_config to enroll a network based on a local
1076	    network configuration block instead of having to (re-)learn the
1077	    current AP settings with wps_er_learn.
1078	  - Allow AP filtering based on IP address, add ctrl_iface event for
1079	    learned AP settings, add wps_er_config command to configure an AP.
1080	* WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2)
1081	  - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool
1082	    for testing protocol extensibility.
1083	  - Add build option CONFIG_WPS_STRICT to allow disabling of WPS
1084	    workarounds.
1085	  - Add support for AuthorizedMACs attribute.
1086	* TDLS:
1087	  - Propogate TDLS related nl80211 capability flags from kernel and
1088	    add them as driver capability flags. If the driver doesn't support
1089	    capabilities, assume TDLS is supported internally. When TDLS is
1090	    explicitly not supported, disable all user facing TDLS operations.
1091	  - Allow TDLS to be disabled at runtime (mostly for testing).
1092	    Use set tdls_disabled.
1093	  - Honor AP TDLS settings that prohibit/allow TDLS.
1094	  - Add a special testing feature for changing TDLS behavior. Use
1095	    CONFIG_TDLS_TESTING build param to enable. Configure at runtime
1096	    with tdls_testing cli command.
1097	  - Add support for TDLS 802.11z.
1098	* wlantest: Add a tool wlantest for IEEE802.11 protocol testing.
1099	  wlantest can be used to capture frames from a monitor interface
1100	  for realtime capturing or from pcap files for offline analysis.
1101	* Interworking: Support added for 802.11u. Enable in .config with
1102	  CONFIG_INTERWORKING. See wpa_supplicant.conf for config parameters
1103	  for interworking. wpa_cli commands added to support this are
1104	  interworking_select, interworking_connect, anqp_get, fetch_anqp,
1105	  and stop_fetch_anqp.
1106	* Android: Add build and runtime support for Android wpa_supplicant.
1107	* bgscan learn: Add new bgscan that learns BSS information based on
1108	  previous scans, and uses that information to dynamically generate
1109	  the list of channels for background scans.
1110	* Add a new debug message level for excessive information. Use
1111	  -ddd to enable.
1112	* TLS: Add support for tls_disable_time_checks=1 in client mode.
1113	* Internal TLS:
1114	  - Add support for TLS v1.1 (RFC 4346). Enable with build parameter
1115	    CONFIG_TLSV11.
1116	  - Add domainComponent parser for X.509 names.
1117	* Linux: Add RFKill support by adding an interface state "disabled".

1119	  WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames.
1120	  Move HT IEs to be later in (Re)Assoc Resp.
1121	* Solaris: Add support for wired 802.1X client.
1122	* Wi-Fi Direct support. See README-P2P for more information.
1123	* Many bugfixes.
1124
11252010-04-18 - v0.7.2
1126	* nl80211: fixed number of issues with roaming
1127	* avoid unnecessary roaming if multiple APs with similar signal
1128	  strength are present in scan results
1129	* add TLS client events and server probing to ease design of
1130	  automatic detection of EAP parameters
1131	* add option for server certificate matching (SHA256 hash of the
1132	  certificate) instead of trusted CA certificate configuration
1133	* bsd: Cleaned up driver wrapper and added various low-level
1134	  configuration options
1135	* wpa_gui-qt4: do not show too frequent WPS AP available events as
1136	  tray messages
1137	* TNC: fixed issues with fragmentation
1138	* EAP-TNC: add Flags field into fragment acknowledgement (needed to
1139	  interoperate with other implementations; may potentially breaks
1140	  compatibility with older wpa_supplicant/hostapd versions)
1141	* wpa_cli: added option for using a separate process to receive event
1142	  messages to reduce latency in showing these
1143	  (CFLAGS += -DCONFIG_WPA_CLI_FORK=y in .config to enable this)
1144	* maximum BSS table size can now be configured (bss_max_count)
1145	* BSSes to be included in the BSS table can be filtered based on
1146	  configured SSIDs to save memory (filter_ssids)
1147	* fix number of issues with IEEE 802.11r/FT; this version is not
1148	  backwards compatible with old versions
1149	* nl80211: add support for IEEE 802.11r/FT protocol (both over-the-air
1150	  and over-the-DS)
1151	* add freq_list network configuration parameter to allow the AP
1152	  selection to filter out entries based on the operating channel
1153	* add signal strength change events for bgscan; this allows more
1154	  dynamic changes to background scanning interval based on changes in
1155	  the signal strength with the current AP; this improves roaming within
1156	  ESS quite a bit, e.g., with bgscan="simple:30:-45:300" in the network
1157	  configuration block to request background scans less frequently when
1158	  signal strength remains good and to automatically trigger background
1159	  scans whenever signal strength drops noticeably
1160	  (this is currently only available with nl80211)
1161	* add BSSID and reason code (if available) to disconnect event messages
1162	* wpa_gui-qt4: more complete support for translating the GUI with
1163	  linguist and add German translation
1164	* fix DH padding with internal crypto code (mainly, for WPS)
1165	* do not trigger initial scan automatically anymore if there are no
1166	  enabled networks
1167
11682010-01-16 - v0.7.1
1169	* cleaned up driver wrapper API (struct wpa_driver_ops); the new API
1170	  is not fully backwards compatible, so out-of-tree driver wrappers
1171	  will need modifications
1172	* cleaned up various module interfaces
1173	* merge hostapd and wpa_supplicant developers' documentation into a
1174	  single document
1175	* nl80211: use explicit deauthentication to clear cfg80211 state to
1176	  avoid issues when roaming between APs
1177	* dbus: major design changes in the new D-Bus API
1178	  (fi.w1.wpa_supplicant1)
1179	* nl80211: added support for IBSS networks
1180	* added internal debugging mechanism with backtrace support and memory
1181	  allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y)
1182	* added WPS ER unsubscription command to more cleanly unregister from
1183	  receiving UPnP events when ER is terminated
1184	* cleaned up AP mode operations to avoid need for virtual driver_ops
1185	  wrapper
1186	* added BSS table to maintain more complete scan result information
1187	  over multiple scans (that may include only partial results)
1188	* wpa_gui-qt4: update Peers dialog information more dynamically while
1189	  the dialog is kept open
1190	* fixed PKCS#12 use with OpenSSL 1.0.0
1191	* driver_wext: Added cfg80211-specific optimization to avoid some
1192	  unnecessary scans and to speed up association
1193
11942009-11-21 - v0.7.0
1195	* increased wpa_cli ping interval to 5 seconds and made this
1196	  configurable with a new command line options (-G<seconds>)
1197	* fixed scan buffer processing with WEXT to handle up to 65535
1198	  byte result buffer (previously, limited to 32768 bytes)
1199	* allow multiple driver wrappers to be specified on command line
1200	  (e.g., -Dnl80211,wext); the first one that is able to initialize the
1201	  interface will be used
1202	* added support for multiple SSIDs per scan request to optimize
1203	  scan_ssid=1 operations in ap_scan=1 mode (i.e., search for hidden
1204	  SSIDs); this requires driver support and can currently be used only
1205	  with nl80211
1206	* added support for WPS USBA out-of-band mechanism with USB Flash
1207	  Drives (UFD) (CONFIG_WPS_UFD=y)
1208	* driver_ndis: add PAE group address to the multicast address list to
1209	  fix wired IEEE 802.1X authentication
1210	* fixed IEEE 802.11r key derivation function to match with the standard
1211	  (note: this breaks interoperability with previous version) [Bug 303]
1212	* added better support for drivers that allow separate authentication
1213	  and association commands (e.g., mac80211-based Linux drivers with
1214	  nl80211; SME in wpa_supplicant); this allows over-the-air FT protocol
1215	  to be used (IEEE 802.11r)
1216	* fixed SHA-256 based key derivation function to match with the
1217	  standard when using CCMP (for IEEE 802.11r and IEEE 802.11w)
1218	  (note: this breaks interoperability with previous version) [Bug 307]
1219	* use shared driver wrapper files with hostapd
1220	* added AP mode functionality (CONFIG_AP=y) with mode=2 in the network
1221	  block; this can be used for open and WPA2-Personal networks
1222	  (optionally, with WPS); this links in parts of hostapd functionality
1223	  into wpa_supplicant
1224	* wpa_gui-qt4: added new Peers dialog to show information about peers
1225	  (other devices, including APs and stations, etc. in the neighborhood)
1226	* added support for WPS External Registrar functionality (configure APs
1227	  and enroll new devices); can be used with wpa_gui-qt4 Peers dialog
1228	  and wpa_cli commands wps_er_start, wps_er_stop, wps_er_pin,
1229	  wps_er_pbc, wps_er_learn
1230	  (this can also be used with a new 'none' driver wrapper if no
1231	  wireless device or IEEE 802.1X on wired is needed)
1232	* driver_nl80211: multiple updates to provide support for new Linux
1233	  nl80211/mac80211 functionality
1234	* updated management frame protection to use IEEE Std 802.11w-2009
1235	* fixed number of small WPS issues and added workarounds to
1236	  interoperate with common deployed broken implementations
1237	* added support for NFC out-of-band mechanism with WPS
1238	* driver_ndis: fixed wired IEEE 802.1X authentication with PAE group
1239	  address frames
1240	* added preliminary support for IEEE 802.11r RIC processing
1241	* added support for specifying subset of enabled frequencies to scan
1242	  (scan_freq option in the network configuration block); this can speed
1243	  up scanning process considerably if it is known that only a small
1244	  subset of channels is actually used in the network (this is currently
1245	  supported only with -Dnl80211)
1246	* added a workaround for race condition between receiving the
1247	  association event and the following EAPOL-Key
1248	* added background scan and roaming infrastructure to allow
1249	  network-specific optimizations to be used to improve roaming within
1250	  an ESS (same SSID)
1251	* added new DBus interface (fi.w1.wpa_supplicant1)
1252
12532009-01-06 - v0.6.7
1254	* added support for Wi-Fi Protected Setup (WPS)
1255	  (wpa_supplicant can now be configured to act as a WPS Enrollee to
1256	  enroll credentials for a network using PIN and PBC methods; in
1257	  addition, wpa_supplicant can act as a wireless WPS Registrar to
1258	  configure an AP); WPS support can be enabled by adding CONFIG_WPS=y
1259	  into .config and setting the runtime configuration variables in
1260	  wpa_supplicant.conf (see WPS section in the example configuration
1261	  file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to
1262	  manage WPS negotiation; see README-WPS for more details
1263	* added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
1264	* added support for using driver_test over UDP socket
1265	* fixed PEAPv0 Cryptobinding interoperability issue with Windows Server
1266	  2008 NPS; optional cryptobinding is now enabled (again) by default
1267	* fixed PSK editing in wpa_gui
1268	* changed EAP-GPSK to use the IANA assigned EAP method type 51
1269	* added a Windows installer that includes WinPcap and all the needed
1270	  DLLs; in addition, it set up the registry automatically so that user
1271	  will only need start wpa_gui to get prompted to start the wpasvc
1272	  servide and add a new interface if needed through wpa_gui dialog
1273	* updated management frame protection to use IEEE 802.11w/D7.0
1274
12752008-11-23 - v0.6.6
1276	* added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
1277	  (can be used to simulate test SIM/USIM card with a known private key;
1278	  enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
1279	  and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
1280	* added a new network configuration option, wpa_ptk_rekey, that can be
1281	  used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
1282	  against TKIP deficiencies
1283	* added an optional mitigation mechanism for certain attacks against
1284	  TKIP by delaying Michael MIC error reports by a random amount of time
1285	  between 0 and 60 seconds; this can be enabled with a build option
1286	  CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
1287	* fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
1288	  not bytes
1289	* updated OpenSSL code for EAP-FAST to use an updated version of the
1290	  session ticket overriding API that was included into the upstream
1291	  OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
1292	  needed with that version anymore)
1293	* updated userspace MLME instructions to match with the current Linux
1294	  mac80211 implementation; please also note that this can only be used
1295	  with driver_nl80211.c (the old code from driver_wext.c was removed)
1296	* added support (Linux only) for RoboSwitch chipsets (often found in
1297	  consumer grade routers); driver interface 'roboswitch'
1298	* fixed canceling of PMKSA caching when using drivers that generate
1299	  RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
1300	  about
1301
13022008-11-01 - v0.6.5
1303	* added support for SHA-256 as X.509 certificate digest when using the
1304	  internal X.509/TLSv1 implementation
1305	* updated management frame protection to use IEEE 802.11w/D6.0
1306	* added support for using SHA256-based stronger key derivation for WPA2
1307	  (IEEE 802.11w)
1308	* fixed FT (IEEE 802.11r) authentication after a failed association to
1309	  use correct FTIE
1310	* added support for configuring Phase 2 (inner/tunneled) authentication
1311	  method with wpa_gui-qt4
1312
13132008-08-10 - v0.6.4
1314	* added support for EAP Sequences in EAP-FAST Phase 2
1315	* added support for using TNC with EAP-FAST
1316	* added driver_ps3 for the PS3 Linux wireless driver
1317	* added support for optional cryptobinding with PEAPv0
1318	* fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
1319	  allow fallback to full handshake if server rejects PAC-Opaque
1320	* added fragmentation support for EAP-TNC
1321	* added support for parsing PKCS #8 formatted private keys into the
1322	  internal TLS implementation (both PKCS #1 RSA key and PKCS #8
1323	  encapsulated RSA key can now be used)
1324	* added option of using faster, but larger, routines in the internal
1325	  LibTomMath (for internal TLS implementation) to speed up DH and RSA
1326	  calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
1327	* fixed race condition between disassociation event and group key
1328	  handshake to avoid getting stuck in incorrect state [Bug 261]
1329	* fixed opportunistic key caching (proactive_key_caching)
1330
13312008-02-22 - v0.6.3
1332	* removed 'nai' and 'eappsk' network configuration variables that were
1333	  previously used for configuring user identity and key for EAP-PSK,
1334	  EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
1335	  replacement for 'nai' (if old configuration used a separate
1336	  'identity' value, that would now be configured as
1337	  'anonymous_identity'). 'password' field is now used as the
1338	  replacement for 'eappsk' (it can also be set using hexstring to
1339	  present random binary data)
1340	* removed '-w' command line parameter (wait for interface to be added,
1341	  if needed); cleaner way of handling this functionality is to use an
1342	  external mechanism (e.g., hotplug scripts) that start wpa_supplicant
1343	  when an interface is added
1344	* updated FT support to use the latest draft, IEEE 802.11r/D9.0
1345	* added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
1346	  indicating when new scan results become available
1347	* added new ctrl_iface command, BSS, to allow scan results to be
1348	  fetched without hitting the message size limits (this command
1349	  can be used to iterate through the scan results one BSS at the time)
1350	* fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
1351	  attributes in EAP-SIM Start/Response when using fast reauthentication
1352	* fixed EAPOL not to end up in infinite loop when processing dynamic
1353	  WEP keys with IEEE 802.1X
1354	* fixed problems in getting NDIS events from WMI on Windows 2000
1355
13562008-01-01 - v0.6.2
1357	* added support for Makefile builds to include debug-log-to-a-file
1358	  functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
1359	* fixed EAP-SIM and EAP-AKA message parser to validate attribute
1360	  lengths properly to avoid potential crash caused by invalid messages
1361	* added data structure for storing allocated buffers (struct wpabuf);
1362	  this does not affect wpa_supplicant usage, but many of the APIs
1363	  changed and various interfaces (e.g., EAP) is not compatible with old
1364	  versions
1365	* added support for protecting EAP-AKA/Identity messages with
1366	  AT_CHECKCODE (optional feature in RFC 4187)
1367	* added support for protected result indication with AT_RESULT_IND for
1368	  EAP-SIM and EAP-AKA (phase1="result_ind=1")
1369	* added driver_wext workaround for race condition between scanning and
1370	  association with drivers that take very long time to scan all
1371	  channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
1372	  using a longer hardcoded timeout for the scan if the driver supports
1373	  notifications for scan completion (SIOCGIWSCAN event); this helps,
1374	  e.g., in cases where wpa_supplicant and madwifi driver ended up in
1375	  loop where the driver did not even try to associate
1376	* stop EAPOL timer tick when no timers are in use in order to reduce
1377	  power consumption (no need to wake up the process once per second)
1378	  [Bug 237]
1379	* added support for privilege separation (run only minimal part of
1380	  wpa_supplicant functionality as root and rest as unprivileged,
1381	  non-root process); see 'Privilege separation' in README for details;
1382	  this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
1383	  in .config
1384	* changed scan results data structure to include all information
1385	  elements to make it easier to support new IEs; old get_scan_result()
1386	  driver_ops is still supported for backwards compatibility (results
1387	  are converted internally to the new format), but all drivers should
1388	  start using the new get_scan_results2() to make them more likely to
1389	  work with new features
1390	* Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
1391	  application, i.e., it does not require Qt3Support anymore; Windows
1392	  binary of wpa_gui.exe is now from this directory and only requires
1393	  QtCore4.dll and QtGui4.dll libraries
1394	* updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
1395	  available as a separate package to make wpa_gui installation easier:
1396	  http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
1397	* added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
1398	  only shared key/password authentication is supported in this version
1399
14002007-11-24 - v0.6.1
1401	* added support for configuring password as NtPasswordHash
1402	  (16-byte MD4 hash of password) in hash:<32 hex digits> format
1403	* added support for fallback from abbreviated TLS handshake to
1404	  full handshake when using EAP-FAST (e.g., due to an expired
1405	  PAC-Opaque)
1406	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
1407	  draft (draft-ietf-emu-eap-gpsk-07.txt)
1408	* added support for drivers that take care of RSN 4-way handshake
1409	  internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
1410	  WPA_ALG_PMK in set_key)
1411	* added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
1412	  .config); this version supports only ap_scan=2 mode and allow the
1413	  driver to take care of the 4-way handshake
1414	* fixed a buffer overflow in parsing TSF from scan results when using
1415	  driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
1416	  [Bug 232]
1417	* updated FT support to use the latest draft, IEEE 802.11r/D8.0
1418	* fixed an integer overflow issue in the ASN.1 parser used by the
1419	  (experimental) internal TLS implementation to avoid a potential
1420	  buffer read overflow
1421	* fixed a race condition with -W option (wait for a control interface
1422	  monitor before starting) that could have caused the first messages to
1423	  be lost
1424	* added support for processing TNCC-TNCS-Messages to report
1425	  recommendation (allow/none/isolate) when using TNC [Bug 243]
1426
14272007-05-28 - v0.6.0
1428	* added network configuration parameter 'frequency' for setting
1429	  initial channel for IBSS (adhoc) networks
1430	* added experimental IEEE 802.11r/D6.0 support
1431	* updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
1432	* updated EAP-PSK to use the IANA-allocated EAP type 47
1433	* fixed EAP-PAX key derivation
1434	* fixed EAP-PSK bit ordering of the Flags field
1435	* fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
1436	  tunnelled identity request (previously, the identifier from the outer
1437	  method was used, not the tunnelled identifier which could be
1438	  different)
1439	* added support for fragmentation of outer TLS packets during Phase 2
1440	  of EAP-PEAP/TTLS/FAST
1441	* fixed EAP-TTLS AVP parser processing for too short AVP lengths
1442	* added support for EAP-FAST authentication with inner methods that
1443	  generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
1444	  for PAC provisioning)
1445	* added support for authenticated EAP-FAST provisioning
1446	* added support for configuring maximum number of EAP-FAST PACs to
1447	  store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
1448	* added support for storing EAP-FAST PACs in binary format
1449	  (fast_pac_format=binary in phase1 string)
1450	* fixed dbus ctrl_iface to validate message interface before
1451	  dispatching to avoid a possible segfault [Bug 190]
1452	* fixed PeerKey key derivation to use the correct PRF label
1453	* updated Windows binary build to link against OpenSSL 0.9.8d and
1454	  added support for EAP-FAST
1455	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
1456	  draft (draft-ietf-emu-eap-gpsk-04.txt)
1457	* fixed EAP-AKA Notification processing to allow Notification to be
1458	  processed after AKA Challenge response has been sent
1459	* updated to use IEEE 802.11w/D2.0 for management frame protection
1460	  (still experimental)
1461	* fixed EAP-TTLS implementation not to crash on use of freed memory
1462	  if TLS library initialization fails
1463	* added support for EAP-TNC (Trusted Network Connect)
1464	  (this version implements the EAP-TNC method and EAP-TTLS changes
1465	  needed to run two methods in sequence (IF-T) and the IF-IMC and
1466	  IF-TNCCS interfaces from TNCC)
1467
14682006-11-24 - v0.5.6
1469	* added experimental, integrated TLSv1 client implementation with the
1470	  needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
1471	  setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
1472	  .config); this can be useful, e.g., if the target system does not
1473	  have a suitable TLS library and a minimal code size is required
1474	  (total size of this internal TLS/crypto code is bit under 50 kB on
1475	  x86 and the crypto code is shared by rest of the supplicant so some
1476	  of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
1477	* removed STAKey handshake since PeerKey handshake has replaced it in
1478	  IEEE 802.11ma and there are no known deployments of STAKey
1479	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
1480	  draft (draft-ietf-emu-eap-gpsk-01.txt)
1481	* added preliminary implementation of IEEE 802.11w/D1.0 (management
1482	  frame protection)
1483	  (Note: this requires driver support to work properly.)
1484	  (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
1485	* fixed Windows named pipes ctrl_iface to not stop listening for
1486	  commands if client program opens a named pipe and closes it
1487	  immediately without sending a command
1488	* fixed USIM PIN status determination for the case that PIN is not
1489	  needed (this allows EAP-AKA to be used with USIM cards that do not
1490	  use PIN)
1491	* added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
1492	  be used with cards that do not support file selection based on
1493	  partial AID
1494	* added support for matching the subjectAltName of the authentication
1495	  server certificate against multiple name components (e.g.,
1496	  altsubject_match="DNS:server.example.com;DNS:server2.example.com")
1497	* fixed EAP-SIM/AKA key derivation for re-authentication case (only
1498	  affects IEEE 802.1X with dynamic WEP keys)
1499	* changed ctrl_iface network configuration 'get' operations to not
1500	  return password/key material; if these fields are requested, "*"
1501	  will be returned if the password/key is set, but the value of the
1502	  parameter is not exposed
1503
15042006-08-27 - v0.5.5
1505	* added support for building Windows version with UNICODE defined
1506	  (wide-char functions)
1507	* driver_ndis: fixed static WEP configuration to avoid race condition
1508	  issues with some NDIS drivers between association and setting WEP
1509	  keys
1510	* driver_ndis: added validation for IELength value in scan results to
1511	  avoid crashes when using buggy NDIS drivers [Bug 165]
1512	* fixed Release|Win32 target in the Visual Studio project files
1513	  (previously, only Debug|Win32 target was set properly)
1514	* changed control interface API call wpa_ctrl_pending() to allow it to
1515	  return -1 on error (e.g., connection lost); control interface clients
1516	  will need to make sure that they verify that the value is indeed >0
1517	  when determining whether there are pending messages
1518	* added an alternative control interface backend for Windows targets:
1519	  Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
1520	  control interface mechanism for Windows builds (previously, UDP to
1521	  localhost was used)
1522	* changed ctrl_interface configuration for UNIX domain sockets:
1523	  - deprecated ctrl_interface_group variable (it may be removed in
1524	    future versions)
1525	  - allow both directory and group be configured with ctrl_interface
1526	    in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
1527	  - ctrl_interface=/var/run/wpa_supplicant is still supported for the
1528	    case when group is not changed
1529	* added support for controlling more than one interface per process in
1530	  Windows version
1531	* added a workaround for a case where the AP is using unknown address
1532	  (e.g., MAC address of the wired interface) as the source address for
1533	  EAPOL-Key frames; previously, that source address was used as the
1534	  destination for EAPOL-Key frames and in key derivation; now, BSSID is
1535	  used even if the source address does not match with it
1536	  (this resolves an interoperability issue with Thomson SpeedTouch 580)
1537	* added a workaround for UDP-based control interface (which was used in
1538	  Windows builds before this release) to prevent packets with forged
1539	  addresses from being accepted as local control requests
1540	* removed ndis_events.cpp and possibility of using external
1541	  ndis_events.exe; C version (ndis_events.c) is fully functional and
1542	  there is no desire to maintain two separate versions of this
1543	  implementation
1544	* ndis_events: Changed NDIS event notification design to use WMI to
1545	  learn the adapter description through Win32_PnPEntity class; this
1546	  should fix some cases where the adapter name was not recognized
1547	  correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
1548	  USB) [Bug 113]
1549	* fixed selection of the first network in ap_scan=2 mode; previously,
1550	  wpa_supplicant could get stuck in SCANNING state when only the first
1551	  network for enabled (e.g., after 'wpa_cli select_network 0')
1552	* winsvc: added support for configuring ctrl_interface parameters in
1553	  registry (ctrl_interface string value in
1554	  HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
1555	  required to enable control interface (previously, this was hardcoded
1556	  to be enabled)
1557	* allow wpa_gui subdirectory to be built with both Qt3 and Qt4
1558	* converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
1559
15602006-06-20 - v0.5.4
1561	* fixed build with CONFIG_STAKEY=y [Bug 143]
1562	* added support for doing MLME (IEEE 802.11 management frame
1563	  processing) in wpa_supplicant when using Devicescape IEEE 802.11
1564	  stack (wireless-dev.git tree)
1565	* added a new network block configuration option, fragment_size, to
1566	  configure the maximum EAP fragment size
1567	* driver_ndis: Disable WZC automatically for the selected interface to
1568	  avoid conflicts with two programs trying to control the radio; WZC
1569	  will be re-enabled (if it was enabled originally) when wpa_supplicant
1570	  is terminated
1571	* added an experimental TLSv1 client implementation
1572	  (CONFIG_TLS=internal) that can be used instead of an external TLS
1573	  library, e.g., to reduce total size requirement on systems that do
1574	  not include any TLS library by default (this is not yet complete;
1575	  basic functionality is there, but certificate validation is not yet
1576	  included)
1577	* added PeerKey handshake implementation for IEEE 802.11e
1578	  direct link setup (DLS) to replace STAKey handshake
1579	* fixed WPA PSK update through ctrl_iface for the case where the old
1580	  PSK was derived from an ASCII passphrase and the new PSK is set as
1581	  a raw PSK (hex string)
1582	* added new configuration option for identifying which network block
1583	  was used (id_str in wpa_supplicant.conf; included on
1584	  WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
1585	  variable in wpa_cli action scripts; in addition WPA_ID variable is
1586	  set to the current unique identifier that wpa_supplicant assigned
1587	  automatically for the network and that can be used with
1588	  GET_NETWORK/SET_NETWORK ctrl_iface commands)
1589	* wpa_cli action script is now called only when the connect/disconnect
1590	  status changes or when associating with a different network
1591	* fixed configuration parser not to remove CCMP from group cipher list
1592	  if WPA-None (adhoc) is used (pairwise=NONE in that case)
1593	* fixed integrated NDIS events processing not to hang the process due
1594	  to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
1595	* added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
1596	  draft-clancy-emu-eap-shared-secret-00.txt)
1597	* added Microsoft Visual Studio 2005 solution and project files for
1598	  build wpa_supplicant for Windows (see vs2005 subdirectory)
1599	* eloop_win: fixed unregistration of Windows events
1600	* l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
1601	  at the end of RSN pre-authentication and added unregistration of
1602	  a Windows event to avoid getting eloop_win stuck with an invalid
1603	  handle
1604	* driver_ndis: added support for selecting AP based on BSSID
1605	* added new environmental variable for wpa_cli action scripts:
1606	  WPA_CTRL_DIR is the current control interface directory
1607	* driver_ndis: added support for using NDISUIO instead of WinPcap for
1608	  OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
1609	  l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
1610	  wpa_supplicant without requiring WinPcap; note that using NDISUIO
1611	  requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
1612	  only one application to open the device
1613	* changed NDIS driver naming to only include device GUID, e.g.,
1614	  {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
1615	  specific \Device\NPF_ prefix before the GUID; the prefix is still
1616	  allowed for backwards compatibility, but it is not required anymore
1617	  when specifying the interface
1618	* driver_ndis: re-initialize driver interface is the adapter is removed
1619	  and re-inserted [Bug 159]
1620	* driver_madwifi: fixed TKIP and CCMP sequence number configuration on
1621	  big endian hosts [Bug 146]
1622
16232006-04-27 - v0.5.3
1624	* fixed EAP-GTC response to include correct user identity when run as
1625	  phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
1626	* driver_ndis: Fixed encryption mode configuration for unencrypted
1627	  networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
1628	  refused to associate with open networks) [Bug 106]
1629	* driver_ndis: use BSSID OID polling to detect when IBSS network is
1630	  formed even when ndis_events code is included since some NDIS drivers
1631	  do not generate media connect events in IBSS mode
1632	* config_winreg: allow global ctrl_interface parameter to be configured
1633	  in Windows registry
1634	* config_winreg: added support for saving configuration data into
1635	  Windows registry
1636	* added support for controlling network device operational state
1637	  (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
1638	  http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
1639	  that can use this information)
1640	* driver_wext: added support for WE-21 change to SSID configuration
1641	* driver_wext: fixed privacy configuration for static WEP keys mode
1642	  [Bug 140]
1643	* added an optional driver_ops callback for MLME-SETPROTECTION.request
1644	  primitive
1645	* added support for EAP-SAKE (no EAP method number allocated yet, so
1646	  this is using the same experimental type 255 as EAP-PSK)
1647	* added support for dynamically loading EAP methods (.so files) instead
1648	  of requiring them to be statically linked in; this is disabled by
1649	  default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
1650	  on how to use this)
1651
16522006-03-19 - v0.5.2
1653	* do not try to use USIM APDUs when initializing PC/SC for SIM card
1654	  access for a network that has not enabled EAP-AKA
1655	* fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
1656	  v0.5.1 due to the new support for expanded EAP types)
1657	* added support for generating EAP Expanded Nak
1658	* try to fetch scan results once before requesting new scan when
1659	  starting up in ap_scan=1 mode (this can speed up initial association
1660	  a lot with, e.g., madwifi-ng driver)
1661	* added support for receiving EAPOL frames from a Linux bridge
1662	  interface (-bbr0 on command line)
1663	* fixed EAPOL re-authentication for sessions that used PMKSA caching
1664	* changed EAP method registration to use a dynamic list of methods
1665	  instead of a static list generated at build time
1666	* fixed PMKSA cache deinitialization not to use freed memory when
1667	  removing PMKSA entries
1668	* fixed a memory leak in EAP-TTLS re-authentication
1669	* reject WPA/WPA2 message 3/4 if it does not include any valid
1670	  WPA/RSN IE
1671	* driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
1672	  if the driver does not support SIOCSIWAUTH
1673
16742006-01-29 - v0.5.1
1675	* driver_test: added better support for multiple APs and STAs by using
1676	  a directory with sockets that include MAC address for each device in
1677	  the name (driver_param=test_dir=/tmp/test)
1678	* added support for EAP expanded type (vendor specific EAP methods)
1679	* added AP_SCAN command into ctrl_iface so that ap_scan configuration
1680	  option can be changed if needed
1681	* wpa_cli/wpa_gui: skip non-socket files in control directory when
1682	  using UNIX domain sockets; this avoids selecting an incorrect
1683	  interface (e.g., a PID file could be in this directory, even though
1684	  use of this directory for something else than socket files is not
1685	  recommended)
1686	* fixed TLS library deinitialization after RSN pre-authentication not
1687	  to disable TLS library for normal authentication
1688	* driver_wext: Remove null-termination from SSID length if the driver
1689	  used it; some Linux drivers do this and they were causing problems in
1690	  wpa_supplicant not finding matching configuration block. This change
1691	  would break a case where the SSID actually ends in '\0', but that is
1692	  not likely to happen in real use.
1693	* fixed PMKSA cache processing not to trigger deauthentication if the
1694	  current PMKSA cache entry is replaced with a valid new entry
1695	* fixed PC/SC initialization for ap_scan != 1 modes (this fixes
1696	  EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
1697	  ap_scan=2)
1698
16992005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
1700	* added experimental STAKey handshake implementation for IEEE 802.11e
1701	  direct link setup (DLS); note: this is disabled by default in both
1702	  build and runtime configuration (can be enabled with CONFIG_STAKEY=y
1703	  and stakey=1)
1704	* fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
1705	  decrypt AT_ENCR_DATA attributes correctly
1706	* fixed EAP-AKA to allow resynchronization within the same session
1707	* made code closer to ANSI C89 standard to make it easier to port to
1708	  other C libraries and compilers
1709	* started moving operating system or C library specific functions into
1710	  wrapper functions defined in os.h and implemented in os_*.c to make
1711	  code more portable
1712	* wpa_supplicant can now be built with Microsoft Visual C++
1713	  (e.g., with the freely available Toolkit 2003 version or Visual
1714	  C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
1715	  example makefile for nmake
1716	* added support for using Windows registry for command line parameters
1717	  (CONFIG_MAIN=main_winsvc) and configuration data
1718	  (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
1719	  contents; this version can be run both as a Windows service and as a
1720	  normal application; 'wpasvc.exe app' to start as applicant,
1721	  'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
1722	  'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
1723	  unregister a service
1724	* made it possible to link ndis_events.exe functionality into
1725	  wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
1726	* added better support for multiple control interface backends
1727	  (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
1728	* fixed PC/SC code to use correct length for GSM AUTH command buffer
1729	  and to not use pioRecvPci with SCardTransmit() calls; these were not
1730	  causing visible problems with pcsc-lite, but Windows Winscard.dll
1731	  refused the previously used parameters; this fixes EAP-SIM and
1732	  EAP-AKA authentication using SIM/USIM card under Windows
1733	* added new event loop implementation for Windows using
1734	  WaitForMultipleObject() instead of select() in order to allow waiting
1735	  for non-socket objects; this can be selected with
1736	  CONFIG_ELOOP=eloop_win in .config
1737	* added support for selecting l2_packet implementation in .config
1738	  (CONFIG_L2_PACKET; following options are available now: linux, pcap,
1739	  winpcap, freebsd, none)
1740	* added new l2_packet implementation for WinPcap
1741	  (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
1742	  reduce latency in EAPOL receive processing from about 100 ms to about
1743	  3 ms
1744	* added support for EAP-FAST key derivation using other ciphers than
1745	  RC4-128-SHA for authentication and AES128-SHA for provisioning
1746	* added support for configuring CA certificate as DER file and as a
1747	  configuration blob
1748	* fixed private key configuration as configuration blob and added
1749	  support for using PKCS#12 as a blob
1750	* tls_gnutls: added support for using PKCS#12 files; added support for
1751	  session resumption
1752	* added support for loading trusted CA certificates from Windows
1753	  certificate store: ca_cert="cert_store://<name>", where <name> is
1754	  likely CA (Intermediate CA certificates) or ROOT (root certificates)
1755	* added C version of ndis_events.cpp and made it possible to build this
1756	  with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
1757	  easily on cross-compilation builds
1758	* added wpasvc.exe into Windows binary release; this is an alternative
1759	  version of wpa_supplicant.exe with configuration backend using
1760	  Windows registry and with the entry point designed to run as a
1761	  Windows service
1762	* integrated ndis_events.exe functionality into wpa_supplicant.exe and
1763	  wpasvc.exe and removed this additional tool from the Windows binary
1764	  release since it is not needed anymore
1765	* load winscard.dll functions dynamically when building with MinGW
1766	  since MinGW does not yet include winscard library
1767
17682005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
1769	* l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
1770	  and WinPcap to receive frames sent to PAE group address
1771	* disable EAP state machine when IEEE 802.1X authentication is not used
1772	  in order to get rid of bogus "EAP failed" messages
1773	* fixed OpenSSL error reporting to go through all pending errors to
1774	  avoid confusing reports of old errors being reported at later point
1775	  during handshake
1776	* fixed configuration file updating to not write empty variables
1777	  (e.g., proto or key_mgmt) that the file parser would not accept
1778	* fixed ADD_NETWORK ctrl_iface command to use the same default values
1779	  for variables as empty network definitions read from config file
1780	  would get
1781	* fixed EAP state machine to not discard EAP-Failure messages in many
1782	  cases (e.g., during TLS handshake)
1783	* fixed a infinite loop in private key reading if the configured file
1784	  cannot be parsed successfully
1785	* driver_madwifi: added support for madwifi-ng
1786	* wpa_gui: do not display password/PSK field contents
1787	* wpa_gui: added CA certificate configuration
1788	* driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
1789	* driver_ndis: include Beacon IEs in AssocInfo in order to notice if
1790	  the new AP is using different WPA/RSN IE
1791	* use longer timeout for IEEE 802.11 association to avoid problems with
1792	  drivers that may take more than five second to associate
1793
17942005-10-27 - v0.4.6
1795	* allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
1796	  RSN IE, but WPA IE would match with wpa_supplicant configuration
1797	* added support for named configuration blobs in order to avoid having
1798	  to use file system for external files (e.g., certificates);
1799	  variables can be set to "blob://<blob name>" instead of file path to
1800	  use a named blob; supported fields: pac_file, client_cert,
1801	  private_key
1802	* fixed RSN pre-authentication (it was broken in the clean up of WPA
1803	  state machine interface in v0.4.5)
1804	* driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
1805	  sure the driver configures broadcast decryption correctly
1806	* added ca_path (and ca_path2) configuration variables that can be used
1807	  to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
1808	  system-wide trusted CA list
1809	* added support for starting wpa_supplicant without a configuration
1810	  file (-C argument must be used to set ctrl_interface parameter for
1811	  this case; in addition, -p argument can be used to provide
1812	  driver_param; these new arguments can also be used with a
1813	  configuration to override the values from the configuration)
1814	* added global control interface that can be optionally used for adding
1815	  and removing network interfaces dynamically (-g command line argument
1816	  for both wpa_supplicant and wpa_cli) without having to restart
1817	  wpa_supplicant process
1818	* wpa_gui:
1819	  - try to save configuration whenever something is modified
1820	  - added WEP key configuration
1821	  - added possibility to edit the current network configuration
1822	* driver_ndis: fixed driver polling not to increase frequency on each
1823	  received EAPOL frame due to incorrectly cancelled timeout
1824	* added simple configuration file examples (in examples subdirectory)
1825	* fixed driver_wext.c to filter wireless events based on ifindex to
1826	  avoid interfaces receiving events from other interfaces
1827	* delay sending initial EAPOL-Start couple of seconds to speed up
1828	  authentication for the most common case of Authenticator starting
1829	  EAP authentication immediately after association
1830
18312005-09-25 - v0.4.5
1832	* added a workaround for clearing keys with ndiswrapper to allow
1833	  roaming from WPA enabled AP to plaintext one
1834	* added docbook documentation (doc/docbook) that can be used to
1835	  generate, e.g., man pages
1836	* l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
1837	  PF_PACKET in order to prepare for network devices that do not use
1838	  Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
1839	* use receipt of EAPOL-Key frame as a lower layer success indication
1840	  for EAP state machine to allow recovery from dropped EAP-Success
1841	  frame
1842	* cleaned up internal EAPOL frame processing by not including link
1843	  layer (Ethernet) header during WPA and EAPOL/EAP processing; this
1844	  header is added only when transmitted the frame; this makes it easier
1845	  to use wpa_supplicant on link layers that use different header than
1846	  Ethernet
1847	* updated EAP-PSK to use draft 9 by default since this can now be
1848	  tested with hostapd; removed support for draft 3, including
1849	  server_nai configuration option from network blocks
1850	* driver_wired: add PAE address to the multicast address list in order
1851	  to be able to receive EAPOL frames with drivers that do not include
1852	  these multicast addresses by default
1853	* driver_wext: add support for WE-19
1854	* added support for multiple configuration backends (CONFIG_BACKEND
1855	  option); currently, only 'file' is supported (i.e., the format used
1856	  in wpa_supplicant.conf)
1857	* added support for updating configuration ('wpa_cli save_config');
1858	  this is disabled by default and can be enabled with global
1859	  update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
1860	  and wpa_gui to store the configuration changes in a permanent store
1861	* added GET_NETWORK ctrl_iface command
1862	  (e.g., 'wpa_cli get_network 0 ssid')
1863
18642005-08-21 - v0.4.4
1865	* replaced OpenSSL patch for EAP-FAST support
1866	  (openssl-tls-extensions.patch) with a more generic and correct
1867	  patch (the new patch is not compatible with the previous one, so the
1868	  OpenSSL library will need to be patched with the new patch in order
1869	  to be able to build wpa_supplicant with EAP-FAST support)
1870	* added support for using Windows certificate store (through CryptoAPI)
1871	  for client certificate and private key operations (EAP-TLS)
1872	  (see wpa_supplicant.conf for more information on how to configure
1873	  this with private_key)
1874	* ported wpa_gui to Windows
1875	* added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
1876	  built with the open source version of the Qt4 for Windows
1877	* allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
1878	  with drivers that do not support WPA
1879	* ndis_events: fixed Windows 2000 support
1880	* added support for enabling/disabling networks from the list of all
1881	  configured networks ('wpa_cli enable_network <network id>' and
1882	  'wpa_cli disable_network <network id>')
1883	* added support for adding and removing network from the current
1884	  configuration ('wpa_cli add_network' and 'wpa_cli remove_network
1885	  <network id>'); added networks are disabled by default and they can
1886	  be enabled with enable_network command once the configuration is done
1887	  for the new network; note: configuration file is not yet updated, so
1888	  these new networks are lost when wpa_supplicant is restarted
1889	* added support for setting network configuration parameters through
1890	  the control interface, for example:
1891	  wpa_cli set_network 0 ssid "\"my network\""
1892	* fixed parsing of strings that include both " and # within double
1893	  quoted area (e.g., "start"#end")
1894	* added EAP workaround for PEAP session resumption: allow outer,
1895	  i.e., not tunneled, EAP-Success to terminate session since; this can
1896	  be disabled with eap_workaround=0
1897	  (this was allowed for PEAPv1 before, but now it is also allowed for
1898	  PEAPv0 since at least one RADIUS authentication server seems to be
1899	  doing this for PEAPv0, too)
1900	* wpa_gui: added preliminary support for adding new networks to the
1901	  wpa_supplicant configuration (double click on the scan results to
1902	  open network configuration)
1903
19042005-06-26 - v0.4.3
1905	* removed interface for external EAPOL/EAP supplicant (e.g.,
1906	  Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
1907	  anymore and is unlikely to be used by anyone
1908	* driver_ndis: fixed WinPcap 3.0 support
1909	* fixed build with CONFIG_DNET_PCAP=y on Linux
1910	* l2_packet: moved different implementations into separate files
1911	  (l2_packet_*.c)
1912
19132005-06-12 - v0.4.2
1914	* driver_ipw: updated driver structures to match with ipw2200-1.0.4
1915	  (note: ipw2100-1.1.0 is likely to require an update to work with
1916	  this)
1917	* added support for using ap_scan=2 mode with multiple network blocks;
1918	  wpa_supplicant will go through the networks one by one until the
1919	  driver reports a successful association; this uses the same order for
1920	  networks as scan_ssid=1 scans, i.e., the priority field is ignored
1921	  and the network block order in the file is used instead
1922	* fixed a potential issue in RSN pre-authentication ending up using
1923	  freed memory if pre-authentication times out
1924	* added support for matching alternative subject name extensions of the
1925	  authentication server certificate; new configuration variables
1926	  altsubject_match and altsubject_match2
1927	* driver_ndis: added support for IEEE 802.1X authentication with wired
1928	  NDIS drivers
1929	* added support for querying private key password (EAP-TLS) through the
1930	  control interface (wpa_cli/wpa_gui) if one is not included in the
1931	  configuration file
1932	* driver_broadcom: fixed couple of memory leaks in scan result
1933	  processing
1934	* EAP-PAX is now registered as EAP type 46
1935	* fixed EAP-PAX MAC calculation
1936	* fixed EAP-PAX CK and ICK key derivation
1937	* added support for using password with EAP-PAX (as an alternative to
1938	  entering key with eappsk); SHA-1 hash of the password will be used as
1939	  the key in this case
1940	* added support for arbitrary driver interface parameters through the
1941	  configuration file with a new driver_param field; this adds a new
1942	  driver_ops function set_param()
1943	* added possibility to override l2_packet module with driver interface
1944	  API (new send_eapol handler); this can be used to implement driver
1945	  specific TX/RX functions for EAPOL frames
1946	* fixed ctrl_interface_group processing for the case where gid is
1947	  entered as a number, not group name
1948	* driver_test: added support for testing hostapd with wpa_supplicant
1949	  by using test driver interface without any kernel drivers or network
1950	  cards
1951
19522005-05-22 - v0.4.1
1953	* driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
1954	  packets to be encrypted; this was apparently broken by the changed
1955	  ioctl order in v0.4.0
1956	* driver_madwifi: added preliminary support for compiling against 'BSD'
1957	  branch of madwifi CVS tree
1958	* added support for EAP-MSCHAPv2 password retries within the same EAP
1959	  authentication session
1960	* added support for password changes with EAP-MSCHAPv2 (used when the
1961	  password has expired)
1962	* added support for reading additional certificates from PKCS#12 files
1963	  and adding them to the certificate chain
1964	* fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
1965	  were used
1966	* fixed a possible double free in EAP-TTLS fast-reauthentication when
1967	  identity or password is entered through control interface
1968	* display EAP Notification messages to user through control interface
1969	  with "CTRL-EVENT-EAP-NOTIFICATION" prefix
1970	* added GUI version of wpa_cli, wpa_gui; this is not build
1971	  automatically with 'make'; use 'make wpa_gui' to build (this requires
1972	  Qt development tools)
1973	* added 'disconnect' command to control interface for setting
1974	  wpa_supplicant in state where it will not associate before
1975	  'reassociate' command has been used
1976	* added support for selecting a network from the list of all configured
1977	  networks ('wpa_cli select_network <network id>'; this disabled all
1978	  other networks; to re-enable, 'wpa_cli select_network any')
1979	* added support for getting scan results through control interface
1980	* added EAP workaround for PEAPv1 session resumption: allow outer,
1981	  i.e., not tunneled, EAP-Success to terminate session since; this can
1982	  be disabled with eap_workaround=0
1983
19842005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
1985	* added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
1986	  used to reduce the size of the wpa_supplicant considerably if
1987	  debugging code is not needed
1988	* fixed EAPOL-Key validation to drop packets with invalid Key Data
1989	  Length; such frames could have crashed wpa_supplicant due to buffer
1990	  overflow
1991	* added support for wired authentication (IEEE 802.1X on wired
1992	  Ethernet); driver interface 'wired'
1993	* obsoleted set_wpa() handler in the driver interface API (it can be
1994	  replaced by moving enable/disable functionality into init()/deinit())
1995	  (calls to set_wpa() are still present for backwards compatibility,
1996	  but they may be removed in the future)
1997	* driver_madwifi: fixed association in plaintext mode
1998	* modified the EAP workaround that accepts EAP-Success with incorrect
1999	  Identifier to be even less strict about verification in order to
2000	  interoperate with some authentication servers
2001	* added support for sending TLS alerts
2002	* added support for 'any' SSID wildcard; if ssid is not configured or
2003	  is set to an empty string, any SSID will be accepted for non-WPA AP
2004	* added support for asking PIN (for SIM) from frontends (e.g.,
2005	  wpa_cli); if a PIN is needed, but not included in the configuration
2006	  file, a control interface request is sent and EAP processing is
2007	  delayed until the PIN is available
2008	* added support for using external devices (e.g., a smartcard) for
2009	  private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
2010	  new wpa_supplicant.conf variables:
2011	  - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
2012	  - network: engine, engine_id, key_id
2013	* added experimental support for EAP-PAX
2014	* added monitor mode for wpa_cli (-a<path to a program to run>) that
2015	  allows external commands (e.g., shell scripts) to be run based on
2016	  wpa_supplicant events, e.g., when authentication has been completed
2017	  and data connection is ready; other related wpa_cli arguments:
2018	  -B (run in background), -P (write PID file); wpa_supplicant has a new
2019	  command line argument (-W) that can be used to make it wait until a
2020	  control interface command is received in order to avoid missing
2021	  events
2022	* added support for opportunistic WPA2 PMKSA key caching (disabled by
2023	  default, can be enabled with proactive_key_caching=1)
2024	* fixed RSN IE in 4-Way Handshake message 2/4 for the case where
2025	  Authenticator rejects PMKSA caching attempt and the driver is not
2026	  using assoc_info events
2027	* added -P<pid file> argument for wpa_supplicant to write the current
2028	  process id into a file
2029
20302005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
2031	* added new phase1 option parameter, include_tls_length=1, to force
2032	  wpa_supplicant to add TLS Message Length field to all TLS messages
2033	  even if the packet is not fragmented; this may be needed with some
2034	  authentication servers
2035	* fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
2036	  using drivers that take care of AP selection (e.g., when using
2037	  ap_scan=2)
2038	* fixed reprocessing of pending request after ctrl_iface requests for
2039	  identity/password/otp
2040	* fixed ctrl_iface requests for identity/password/otp in Phase 2 of
2041	  EAP-PEAP and EAP-TTLS
2042	* all drivers using driver_wext: set interface up and select Managed
2043	  mode when starting wpa_supplicant; set interface down when exiting
2044	* renamed driver_ipw2100.c to driver_ipw.c since it now supports both
2045	  ipw2100 and ipw2200; please note that this also changed the
2046	  configuration variable in .config to CONFIG_DRIVER_IPW
2047
20482005-01-24 - v0.3.6
2049	* fixed a busy loop introduced in v0.3.5 for scan result processing
2050	  when no matching AP is found
2051
20522005-01-23 - v0.3.5
2053	* added a workaround for an interoperability issue with a Cisco AP
2054	  when using WPA2-PSK
2055	* fixed non-WPA IEEE 802.1X to use the same authentication timeout as
2056	  WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
2057	  retransmission of dropped frames)
2058	* fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
2059	  (e.g., segfault when processing EAPOL-Key frames)
2060	* fixed EAP workaround and fast reauthentication configuration for
2061	  RSN pre-authentication; previously these were disabled and
2062	  pre-authentication would fail if the used authentication server
2063	  requires EAP workarounds
2064	* added support for blacklisting APs that fail or timeout
2065	  authentication in ap_scan=1 mode so that all APs are tried in cases
2066	  where the ones with strongest signal level are failing authentication
2067	* fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
2068	  authentication attempt
2069	* allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
2070	  in the previous authentication (previously, only Phase 1 success was
2071	  verified)
2072
20732005-01-09 - v0.3.4
2074	* added preliminary support for IBSS (ad-hoc) mode configuration
2075	  (mode=1 in network block); this included a new key_mgmt mode
2076	  WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
2077	  key management; see wpa_supplicant.conf for more details and an
2078	  example on how to configure this (note: this is currently implemented
2079	  only for driver_hostapd.c, but the changes should be trivial to add
2080	  in associate() handler for other drivers, too (assuming the driver
2081	  supports WPA-None)
2082	* added preliminary port for native Windows (i.e., no cygwin) using
2083	  mingw
2084
20852005-01-02 - v0.3.3
2086	* added optional support for GNU Readline and History Libraries for
2087	  wpa_cli (CONFIG_READLINE)
2088	* cleaned up EAP state machine <-> method interface and number of
2089	  small problems with error case processing not terminating on
2090	  EAP-Failure but waiting for timeout
2091	* added couple of workarounds for interoperability issues with a
2092	  Cisco AP when using WPA2
2093	* added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
2094	  Note: This requires a patch for openssl to add support for TLS
2095	  extensions and number of workarounds for operations without
2096	  certificates. Proof of concept type of experimental patch is
2097	  included in openssl-tls-extensions.patch.
2098
20992004-12-19 - v0.3.2
2100	* fixed private key loading for cases where passphrase is not set
2101	* fixed Windows/cygwin L2 packet handler freeing; previous version
2102	  could cause a segfault when RSN pre-authentication was completed
2103	* added support for PMKSA caching with drivers that generate RSN IEs
2104	  (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
2105	  but similar code can be easily added to driver_ndiswrapper.c once
2106	  ndiswrapper gets full support for RSN PMKSA caching
2107	* improved recovery from PMKID mismatches by requesting full EAP
2108	  authentication in case of failed PMKSA caching attempt
2109	* driver_ndis: added support for NDIS NdisMIncidateStatus() events
2110	  (this requires that ndis_events is ran while wpa_supplicant is
2111	  running)
2112	* driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
2113	* added support for driver interfaces to replace the interface name
2114	  based on driver/OS specific mapping, e.g., in case of driver_ndis,
2115	  this allows the beginning of the adapter description to be used as
2116	  the interface name
2117	* added support for CR+LF (Windows-style) line ends in configuration
2118	  file
2119	* driver_ndis: enable radio before starting scanning, disable radio
2120	  when exiting
2121	* modified association event handler to set portEnabled = FALSE before
2122	  clearing port Valid in order to reset EAP state machine and avoid
2123	  problems with new authentication getting ignored because of state
2124	  machines ending up in AUTHENTICATED/SUCCESS state based on old
2125	  information
2126	* added support for driver events to add PMKID candidates in order to
2127	  allow drivers to give priority to most likely roaming candidates
2128	* driver_hostap: moved PrivacyInvoked configuration to associate()
2129	  function so that this will not be set for plaintext connections
2130	* added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
2131	  interface can distinguish plaintext and IEEE 802.1X (no WPA)
2132	  authentication
2133	* fixed static WEP key configuration to use broadcast/default type for
2134	  all keys (previously, the default TX key was configured as pairwise/
2135	  unicast key)
2136	* driver_ndis: added legacy WPA capability detection for non-WPA2
2137	  drivers
2138	* added support for setting static WEP keys for IEEE 802.1X without
2139	  dynamic WEP keying (eapol_flags=0)
2140
21412004-12-12 - v0.3.1
2142	* added support for reading PKCS#12 (PFX) files (as a replacement for
2143	  PEM/DER) to get certificate and private key (CONFIG_PKCS12)
2144	* fixed compilation with CONFIG_PCSC=y
2145	* added new ap_scan mode, ap_scan=2, for drivers that take care of
2146	  association, but need to be configured with security policy and SSID,
2147	  e.g., ndiswrapper and NDIS driver; this mode should allow such
2148	  drivers to work with hidden SSIDs and optimized roaming; when
2149	  ap_scan=2 is used, only the first network block in the configuration
2150	  file is used and this configuration should have explicit security
2151	  policy (i.e., only one option in the lists) for key_mgmt, pairwise,
2152	  group, proto variables
2153	* added experimental port of wpa_supplicant for Windows
2154	  - driver_ndis.c driver interface (NDIS OIDs)
2155	  - currently, this requires cygwin and WinPcap
2156	  - small utility, win_if_list, can be used to get interface name
2157	* control interface can now be removed at build time; add
2158	  CONFIG_CTRL_IFACE=y to .config to maintain old functionality
2159	* optional Xsupplicant interface can now be removed at build time;
2160	  (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
2161	* added auth_alg to driver interface associate() parameters to make it
2162	  easier for drivers to configure authentication algorithm as part of
2163	  the association
2164
21652004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
2166	* driver_broadcom: added new driver interface for Broadcom wl.o driver
2167	  (a generic driver for Broadcom IEEE 802.11a/g cards)
2168	* wpa_cli: fixed parsing of -p <path> command line argument
2169	* PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
2170	  ACK, not tunneled EAP-Success (of which only the first byte was
2171	  actually send due to a bug in previous code); this seems to
2172	  interoperate with most RADIUS servers that implements PEAPv1
2173	* PEAPv1: added support for terminating PEAP authentication on tunneled
2174	  EAP-Success message; this can be configured by adding
2175	  peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
2176	  (some RADIUS servers require this whereas others require a tunneled
2177	  reply
2178	* PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
2179	  the old label for key derivation; previously, the default was 1,
2180	  but it looks like most existing PEAPv1 implementations use the old
2181	  label which is thus more suitable default option
2182	* added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
2183	* fixed parsing of wep_tx_keyidx
2184	* added support for configuring list of allowed Phase 2 EAP types
2185	  (for both EAP-PEAP and EAP-TTLS) instead of only one type
2186	* added support for configuring IEEE 802.11 authentication algorithm
2187	  (auth_alg; mainly for using Shared Key authentication with static
2188	  WEP keys)
2189	* added support for EAP-AKA (with UMTS SIM)
2190	* fixed couple of errors in PCSC handling that could have caused
2191	  random-looking errors for EAP-SIM
2192	* added support for EAP-SIM pseudonyms and fast re-authentication
2193	* added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
2194	  session resumption)
2195	* added support for EAP-SIM with two challanges
2196	  (phase1="sim_min_num_chal=3" can be used to require three challenges)
2197	* added support for configuring DH/DSA parameters for an ephemeral DH
2198	  key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
2199	  dh_file and dh_file2 (phase 2); this adds support for using DSA keys
2200	  and optional DH key exchange to achieve forward secracy with RSA keys
2201	* added support for matching subject of the authentication server
2202	  certificate with a substring when using EAP-TLS/PEAP/TTLS; new
2203	  configuration variables subject_match and subject_match2
2204	* changed SSID configuration in driver_wext.c (used by many driver
2205	  interfaces) to use ssid_len+1 as the length for SSID since some Linux
2206	  drivers expect this
2207	* fixed couple of unaligned reads in scan result parsing to fix WPA
2208	  connection on some platforms (e.g., ARM)
2209	* added driver interface for Intel ipw2100 driver
2210	* added support for LEAP with WPA
2211	* added support for larger scan results report (old limit was 4 kB of
2212	  data, i.e., about 35 or so APs) when using Linux wireless extensions
2213	  v17 or newer
2214	* fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
2215	  only if there is a PMKSA cache entry for the current AP
2216	* fixed error handling for case where reading of scan results fails:
2217	  must schedule a new scan or wpa_supplicant will remain waiting
2218	  forever
2219	* changed debug output to remove shared password/key material by
2220	  default; all key information can be included with -K command line
2221	  argument to match the previous behavior
2222	* added support for timestamping debug log messages (disabled by
2223	  default, can be enabled with -t command line argument)
2224	* set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
2225	  if keys are not configured to be used; this fixes IEEE 802.1X mode
2226	  with drivers that use this information to configure whether Privacy
2227	  bit can be in Beacon frames (e.g., ndiswrapper)
2228	* avoid clearing driver keys if no keys have been configured since last
2229	  key clear request; this seems to improve reliability of group key
2230	  handshake for ndiswrapper & NDIS driver which seems to be suffering
2231	  of some kind of timing issue when the keys are cleared again after
2232	  association
2233	* changed driver interface API:
2234	  - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
2235	    version is being used (now, this is set to 2; previously, it was
2236	    not defined)
2237	  - pass pointer to private data structure to all calls
2238	  - the new API is not backwards compatible; all in-tree driver
2239	    interfaces has been converted to the new API
2240	* added support for controlling multiple interfaces (radios) per
2241	  wpa_supplicant process; each interface needs to be listed on the
2242	  command line (-c, -i, -D arguments) with -N as a separator
2243	  (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
2244	* added a workaround for EAP servers that incorrectly use same Id for
2245	  sequential EAP packets
2246	* changed libpcap/libdnet configuration to use .config variable,
2247	  CONFIG_DNET_PCAP, instead of requiring Makefile modification
2248	* improved downgrade attack detection in IE verification of msg 3/4:
2249	  verify both WPA and RSN IEs, if present, not only the selected one;
2250	  reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
2251	  Probe Response frame, and RSN is enabled in wpa_supplicant
2252	  configuration
2253	* fixed WPA msg 3/4 processing to allow Key Data field contain other
2254	  IEs than just one WPA IE
2255	* added support for FreeBSD and driver interface for the BSD net80211
2256	  layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
2257	  required kernel mods have not yet been committed
2258	* made EAP workarounds configurable; enabled by default, can be
2259	  disabled with network block option eap_workaround=0
2260
22612004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
2262	* resolved couple of interoperability issues with EAP-PEAPv1 and
2263	  Phase 2 (inner EAP) fragment reassembly
2264	* driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
2265	  AP is using non-zero key index for the unicast key and key index zero
2266	  for the broadcast key
2267	* driver_hostap: fixed IEEE 802.1X WEP key updates and
2268	  re-authentication by allowing unencrypted EAPOL frames when not using
2269	  WPA
2270	* added a new driver interface, 'wext', which uses only standard,
2271	  driver independent functionality in Linux wireless extensions;
2272	  currently, this can be used only for non-WPA IEEE 802.1X mode, but
2273	  eventually, this is to be extended to support full WPA/WPA2 once
2274	  Linux wireless extensions get support for this
2275	* added support for mode in which the driver is responsible for AP
2276	  scanning and selection; this is disabled by default and can be
2277	  enabled with global ap_scan=0 variable in wpa_supplicant.conf;
2278	  this mode can be used, e.g., with generic 'wext' driver interface to
2279	  use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
2280	  supporting wireless extensions.
2281	* driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
2282	  operation with an AP that does not include SSID in the Beacon frames)
2283	* added support for new EAP authentication methods:
2284	  EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
2285	* added support for asking one-time-passwords from frontends (e.g.,
2286	  wpa_cli); this 'otp' command works otherwise like 'password' command,
2287	  but the password is used only once and the frontend will be asked for
2288	  a new password whenever a request from authenticator requires a
2289	  password; this can be used with both EAP-OTP and EAP-GTC
2290	* changed wpa_cli to automatically re-establish connection so that it
2291	  does not need to be re-started when wpa_supplicant is terminated and
2292	  started again
2293	* improved user data (identity/password/otp) requests through
2294	  frontends: process pending EAPOL packets after getting new
2295	  information so that full authentication does not need to be
2296	  restarted; in addition, send pending requests again whenever a new
2297	  frontend is attached
2298	* changed control frontends to use a new directory for socket files to
2299	  make it easier for wpa_cli to automatically select between interfaces
2300	  and to provide access control for the control interface;
2301	  wpa_supplicant.conf: ctrl_interface is now a path
2302	  (/var/run/wpa_supplicant is the recommended path) and
2303	  ctrl_interface_group can be used to select which group gets access to
2304	  the control interface;
2305	  wpa_cli: by default, try to connect to the first interface available
2306	  in /var/run/wpa_supplicant; this path can be overriden with -p option
2307	  and an interface can be selected with -i option (i.e., in most common
2308	  cases, wpa_cli does not need to get any arguments)
2309	* added support for LEAP
2310	* added driver interface for Linux ndiswrapper
2311	* added priority option for network blocks in the configuration file;
2312	  this allows networks to be grouped based on priority (the scan
2313	  results are searched for matches with network blocks in this order)
2314
23152004-06-20 - v0.2.3
2316	* sort scan results to improve AP selection
2317	* fixed control interface socket removal for some error cases
2318	* improved scan requesting and authentication timeout
2319	* small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
2320	  TLS processing
2321	* PEAP version can now be forced with phase1="peapver=<ver>"
2322	  (mostly for testing; by default, the highest version supported by
2323	  both the Supplicant and Authentication Server is selected
2324	  automatically)
2325	* added support for madwifi driver (Atheros ar521x)
2326	* added a workaround for cases where AP sets Install Tx/Rx bit for
2327	  WPA Group Key messages when pairwise keys are used (without this,
2328	  the Group Key would be used for Tx and the AP would drop frames
2329	  from the station)
2330	* added GSM SIM/USIM interface for GSM authentication algorithm for
2331	  EAP-SIM; this requires pcsc-lite
2332	* added support for ATMEL AT76C5XXx driver
2333	* fixed IEEE 802.1X WEP key derivation in the case where Authenticator
2334	  does not include key data in the EAPOL-Key frame (i.e., part of
2335	  EAP keying material is used as data encryption key)
2336	* added support for using plaintext and static WEP networks
2337	  (key_mgmt=NONE)
2338
23392004-05-31 - v0.2.2
2340	* added support for new EAP authentication methods:
2341	  EAP-TTLS/EAP-MD5-Challenge
2342	  EAP-TTLS/EAP-GTC
2343	  EAP-TTLS/EAP-MSCHAPv2
2344	  EAP-TTLS/EAP-TLS
2345	  EAP-TTLS/MSCHAPv2
2346	  EAP-TTLS/MSCHAP
2347	  EAP-TTLS/PAP
2348	  EAP-TTLS/CHAP
2349	  EAP-PEAP/TLS
2350	  EAP-PEAP/GTC
2351	  EAP-PEAP/MD5-Challenge
2352	  EAP-GTC
2353	  EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
2354	* added support for anonymous identity (to be used when identity is
2355	  sent in plaintext; real identity will be used within TLS protected
2356	  tunnel (e.g., with EAP-TTLS)
2357	* added event messages from wpa_supplicant to frontends, e.g., wpa_cli
2358	* added support for requesting identity and password information using
2359	  control interface; in other words, the password for EAP-PEAP or
2360	  EAP-TTLS does not need to be included in the configuration file since
2361	  a frontand (e.g., wpa_cli) can ask it from the user
2362	* improved RSN pre-authentication to use a candidate list and process
2363	  all candidates from each scan; not only one per scan
2364	* fixed RSN IE and WPA IE capabilities field parsing
2365	* ignore Tx bit in GTK IE when Pairwise keys are used
2366	* avoid making new scan requests during IEEE 802.1X negotiation
2367	* use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
2368	  with TLS support (this replaces the included implementation with
2369	  library code to save about 8 kB since the library code is needed
2370	  anyway for TLS)
2371	* fixed WPA-PSK only mode when compiled without IEEE 802.1X support
2372	  (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
2373
23742004-05-06 - v0.2.1
2375	* added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
2376	  Supplicant
2377	  - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
2378	  - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
2379	  - EAP-MD5 (cannot be used with WPA-RADIUS)
2380	    [draft-ietf-eap-rfc2284bis-09.txt]
2381	  - EAP-TLS [RFC 2716]
2382	  - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
2383	  - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
2384	    [draft-kamath-pppext-eap-mschapv2-00.txt]
2385	    (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
2386	    default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
2387	  - new configuration file options: eap, identity, password, ca_cert,
2388	    client_cert, privatekey, private_key_passwd
2389	  - Xsupplicant is not required anymore, but it can be used by
2390	    disabling the internal IEEE 802.1X Supplicant with -e command line
2391	    option
2392	  - this code is not included in the default build; Makefile need to
2393	    be edited for this (uncomment lines for selected functionality)
2394	  - EAP-TLS and EAP-PEAP require openssl libraries
2395	* use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
2396	* added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
2397	  (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
2398	   EAPOL-Key frames instead of WPA key handshakes)
2399	* added support for IEEE 802.11i/RSN (WPA2)
2400	  - improved PTK Key Handshake
2401	  - PMKSA caching, pre-authentication
2402	* fixed wpa_supplicant to ignore possible extra data after WPA
2403	  EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
2404	  TPTK' error from message 3 of 4-Way Handshake in case the AP
2405	  includes extra data after the EAPOL-Key)
2406	* added interface for external programs (frontends) to control
2407	  wpa_supplicant
2408	  - CLI example (wpa_cli) with interactive mode and command line
2409	    mode
2410	  - replaced SIGUSR1 status/statistics with the new control interface
2411	* made some feature compile time configurable
2412	  - .config file for make
2413	  - driver interfaces (hostap, hermes, ..)
2414	  - EAPOL/EAP functions
2415
24162004-02-15 - v0.2.0
2417	* Initial version of wpa_supplicant
