966	  operations; this removes the now unused disassociate() wpa_driver_ops
967	  callback
968	* optimized PSK generation on P2P GO by caching results to avoid
969	  multiple PBKDF2 operations
970	* added okc=1 global configuration parameter to allow OKC to be enabled
971	  by default for all network blocks
972	* added a workaround for WPS PBC session overlap detection to avoid
973	  interop issues with deployed station implementations that do not
974	  remove active PBC indication from Probe Request frames properly
975	* added basic support for 60 GHz band
976	* extend EAPOL frames processing workaround for roaming cases
977	  (postpone processing of unexpected EAPOL frame until association

979
9802012-05-10 - v1.0
981	* bsd: Add support for setting HT values in IFM_MMASK.
982	* Delay STA entry removal until Deauth/Disassoc TX status in AP mode.
983	  This allows the driver to use PS buffering of Deauthentication and

985	  available with drivers that provide TX status events for Deauth/
986	  Disassoc frames (nl80211).
987	* Drop oldest unknown BSS table entries first. This makes it less
988	  likely to hit connection issues in environments with huge number
989	  of visible APs.
990	* Add systemd support.
991	* Add support for setting the syslog facility from the config file
992	  at build time.

995	  config parameter ieee80211n.
996	* Allow AP mode to disconnect STAs based on low ACK condition (when
997	  the data connection is not working properly, e.g., due to the STA
998	  going outside the range of the AP). Disabled by default, enable by
999	  config option disassoc_low_ack.
1000	* nl80211:
1001	  - Support GTK rekey offload.
1002	  - Support PMKSA candidate events. This adds support for RSN

1017	  - Emit property changed events (for property BSSs) when adding/
1018	    removing BSSs.
1019	  - Treat '' in SSIDs of Interface.Scan as a request for broadcast
1020	    scan, instead of ignoring it.
1021	  - Add DBus getter/setter for FastReauth.
1022	  - Raise PropertiesChanged on org.freedesktop.DBus.Properties.
1023	* wpa_cli:
1024	  - Send AP-STA-DISCONNECTED event when an AP disconnects a station
1025	    due to inactivity.
1026	  - Make second argument to set command optional. This can be used to
1027	    indicate a zero length value.
1028	  - Add signal_poll command.
1029	  - Add bss_expire_age and bss_expire_count commands to set/get BSS
1030	    cache expiration age and expiration scan count.
1031	  - Add ability to set scan interval (the time in seconds wpa_s waits
1032	    before requesting a new scan after failing to find a suitable
1033	    network in scan results) using scan_interval command.
1034	  - Add event CTRL-EVENT-ASSOC-REJECT for association rejected.
1035	  - Add command get version, that returns wpa_supplicant version string.
1036	  - Add command sta_autoconnect for disabling automatic reconnection
1037	    on receiving disconnection event.
1038	  - Setting bssid parameter to an empty string "" or any can now be
1039	    used to clear the bssid_set flag in a network block, i.e., to remove
1040	    bssid filtering.
1041	  - Add tdls_testing command to add a special testing feature for
1042	    changing TDLS behavior. Build param CONFIG_TDLS_TESTING must be
1043	    enabled as well.
1044	  - For interworking, add wpa_cli commands interworking_select,
1045	    interworking_connect, anqp_get, fetch_anqp, and stop_fetch_anqp.
1046	  - Many P2P commands were added. See README-P2P.

1051	  - Add note command, which can be used to insert notes to the debug
1052	    log.
1053	  - Add internal line edit implementation. CONFIG_WPA_CLI_EDIT=y
1054	    can now be used to build wpa_cli with internal implementation of
1055	    line editing and history support. This can be used as a replacement
1056	    for CONFIG_READLINE=y.
1057	* AP mode: Add max_num_sta config option, which can be used to limit
1058	  the number of stations allowed to connect to the AP.
1059	* Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad
1060	  config file.
1061	* wext: Increase scan timeout from 5 to 10 seconds.

1063	  manage the BSS blacklist and display its current contents.
1064	* WPS:
1065	  - Add wpa_cli wps_pin get command for generating random PINs. This can
1066	    be used in a UI to generate a PIN without starting WPS (or P2P)
1067	    operation.
1068	  - Set RF bands based on driver capabilities, instead of hardcoding
1069	    them.

1076	    validate the checksum digit (if present).
1077	  - Cancel WPS operation on PBC session overlap detection.
1078	  - New wps_cancel command in wpa_cli will cancel a pending WPS
1079	    operation.
1080	  - wpa_cli action: Add WPS_EVENT_SUCCESS and WPS_EVENT_FAIL handlers.
1081	  - Trigger WPS config update on Manufacturer, Model Name, Model
1082	    Number, and Serial Number changes.
1083	  - Fragment size is now configurable for EAP-WSC peer. Use
1084	    wpa_cli set wps_fragment_size <val>.
1085	  - Disable AP PIN after 10 consecutive failures. Slow down attacks on
1086	    failures up to 10.
1087	  - Allow AP to start in Enrollee mode without AP PIN for probing, to
1088	    be compatible with Windows 7.
1089	  - Add Config Error into WPS-FAIL events to provide more info to the
1090	    user on how to resolve the issue.
1091	  - Label and Display config methods are not allowed to be enabled
1092	    at the same time, since it is unclear which PIN to use if both
1093	    methods are advertised.
1094	  - When controlling multiple interfaces:
1095	     - apply WPS commands to all interfaces configured to use WPS
1096	     - apply WPS config changes to all interfaces that use WPS
1097	     - when an attack is detected on any interface, disable AP PIN on
1098	       all interfaces
1099	* WPS ER:
1100	  - Add special AP Setup Locked mode to allow read only ER.
1101	    ap_setup_locked=2 can now be used to enable a special mode where
1102	    WPS ER can learn the current AP settings, but cannot change them.
1103	  - Show SetSelectedRegistrar events as ctrl_iface events
1104	  - Add wps_er_set_config to enroll a network based on a local
1105	    network configuration block instead of having to (re-)learn the
1106	    current AP settings with wps_er_learn.
1107	  - Allow AP filtering based on IP address, add ctrl_iface event for
1108	    learned AP settings, add wps_er_config command to configure an AP.
1109	* WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2)

1113	    workarounds.
1114	  - Add support for AuthorizedMACs attribute.
1115	* TDLS:
1116	  - Propagate TDLS related nl80211 capability flags from kernel and
1117	    add them as driver capability flags. If the driver doesn't support
1118	    capabilities, assume TDLS is supported internally. When TDLS is
1119	    explicitly not supported, disable all user facing TDLS operations.
1120	  - Allow TDLS to be disabled at runtime (mostly for testing).
1121	    Use set tdls_disabled.
1122	  - Honor AP TDLS settings that prohibit/allow TDLS.
1123	  - Add a special testing feature for changing TDLS behavior. Use
1124	    CONFIG_TDLS_TESTING build param to enable. Configure at runtime
1125	    with tdls_testing cli command.

1129	  for realtime capturing or from pcap files for offline analysis.
1130	* Interworking: Support added for 802.11u. Enable in .config with
1131	  CONFIG_INTERWORKING. See wpa_supplicant.conf for config parameters
1132	  for interworking. wpa_cli commands added to support this are
1133	  interworking_select, interworking_connect, anqp_get, fetch_anqp,
1134	  and stop_fetch_anqp.
1135	* Android: Add build and runtime support for Android wpa_supplicant.
1136	* bgscan learn: Add new bgscan that learns BSS information based on
1137	  previous scans, and uses that information to dynamically generate
1138	  the list of channels for background scans.
1139	* Add a new debug message level for excessive information. Use
1140	  -ddd to enable.
1141	* TLS: Add support for tls_disable_time_checks=1 in client mode.
1142	* Internal TLS:
1143	  - Add support for TLS v1.1 (RFC 4346). Enable with build parameter
1144	    CONFIG_TLSV11.

1153
11542010-04-18 - v0.7.2
1155	* nl80211: fixed number of issues with roaming
1156	* avoid unnecessary roaming if multiple APs with similar signal
1157	  strength are present in scan results
1158	* add TLS client events and server probing to ease design of
1159	  automatic detection of EAP parameters
1160	* add option for server certificate matching (SHA256 hash of the
1161	  certificate) instead of trusted CA certificate configuration
1162	* bsd: Cleaned up driver wrapper and added various low-level
1163	  configuration options
1164	* wpa_gui-qt4: do not show too frequent WPS AP available events as
1165	  tray messages
1166	* TNC: fixed issues with fragmentation
1167	* EAP-TNC: add Flags field into fragment acknowledgement (needed to
1168	  interoperate with other implementations; may potentially breaks
1169	  compatibility with older wpa_supplicant/hostapd versions)
1170	* wpa_cli: added option for using a separate process to receive event
1171	  messages to reduce latency in showing these
1172	  (CFLAGS += -DCONFIG_WPA_CLI_FORK=y in .config to enable this)
1173	* maximum BSS table size can now be configured (bss_max_count)
1174	* BSSes to be included in the BSS table can be filtered based on
1175	  configured SSIDs to save memory (filter_ssids)
1176	* fix number of issues with IEEE 802.11r/FT; this version is not
1177	  backwards compatible with old versions
1178	* nl80211: add support for IEEE 802.11r/FT protocol (both over-the-air
1179	  and over-the-DS)
1180	* add freq_list network configuration parameter to allow the AP
1181	  selection to filter out entries based on the operating channel
1182	* add signal strength change events for bgscan; this allows more
1183	  dynamic changes to background scanning interval based on changes in
1184	  the signal strength with the current AP; this improves roaming within
1185	  ESS quite a bit, e.g., with bgscan="simple:30:-45:300" in the network
1186	  configuration block to request background scans less frequently when
1187	  signal strength remains good and to automatically trigger background
1188	  scans whenever signal strength drops noticeably
1189	  (this is currently only available with nl80211)
1190	* add BSSID and reason code (if available) to disconnect event messages
1191	* wpa_gui-qt4: more complete support for translating the GUI with
1192	  linguist and add German translation
1193	* fix DH padding with internal crypto code (mainly, for WPS)
1194	* do not trigger initial scan automatically anymore if there are no
1195	  enabled networks
1196
11972010-01-16 - v0.7.1
1198	* cleaned up driver wrapper API (struct wpa_driver_ops); the new API
1199	  is not fully backwards compatible, so out-of-tree driver wrappers
1200	  will need modifications
1201	* cleaned up various module interfaces
1202	* merge hostapd and wpa_supplicant developers' documentation into a
1203	  single document
1204	* nl80211: use explicit deauthentication to clear cfg80211 state to
1205	  avoid issues when roaming between APs
1206	* dbus: major design changes in the new D-Bus API
1207	  (fi.w1.wpa_supplicant1)
1208	* nl80211: added support for IBSS networks
1209	* added internal debugging mechanism with backtrace support and memory
1210	  allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y)
1211	* added WPS ER unsubscription command to more cleanly unregister from
1212	  receiving UPnP events when ER is terminated
1213	* cleaned up AP mode operations to avoid need for virtual driver_ops
1214	  wrapper
1215	* added BSS table to maintain more complete scan result information
1216	  over multiple scans (that may include only partial results)
1217	* wpa_gui-qt4: update Peers dialog information more dynamically while
1218	  the dialog is kept open
1219	* fixed PKCS#12 use with OpenSSL 1.0.0
1220	* driver_wext: Added cfg80211-specific optimization to avoid some
1221	  unnecessary scans and to speed up association
1222
12232009-11-21 - v0.7.0
1224	* increased wpa_cli ping interval to 5 seconds and made this
1225	  configurable with a new command line options (-G<seconds>)
1226	* fixed scan buffer processing with WEXT to handle up to 65535
1227	  byte result buffer (previously, limited to 32768 bytes)
1228	* allow multiple driver wrappers to be specified on command line
1229	  (e.g., -Dnl80211,wext); the first one that is able to initialize the
1230	  interface will be used
1231	* added support for multiple SSIDs per scan request to optimize
1232	  scan_ssid=1 operations in ap_scan=1 mode (i.e., search for hidden
1233	  SSIDs); this requires driver support and can currently be used only
1234	  with nl80211
1235	* added support for WPS USBA out-of-band mechanism with USB Flash
1236	  Drives (UFD) (CONFIG_WPS_UFD=y)
1237	* driver_ndis: add PAE group address to the multicast address list to
1238	  fix wired IEEE 802.1X authentication
1239	* fixed IEEE 802.11r key derivation function to match with the standard
1240	  (note: this breaks interoperability with previous version) [Bug 303]
1241	* added better support for drivers that allow separate authentication
1242	  and association commands (e.g., mac80211-based Linux drivers with
1243	  nl80211; SME in wpa_supplicant); this allows over-the-air FT protocol
1244	  to be used (IEEE 802.11r)
1245	* fixed SHA-256 based key derivation function to match with the
1246	  standard when using CCMP (for IEEE 802.11r and IEEE 802.11w)
1247	  (note: this breaks interoperability with previous version) [Bug 307]
1248	* use shared driver wrapper files with hostapd
1249	* added AP mode functionality (CONFIG_AP=y) with mode=2 in the network
1250	  block; this can be used for open and WPA2-Personal networks
1251	  (optionally, with WPS); this links in parts of hostapd functionality
1252	  into wpa_supplicant
1253	* wpa_gui-qt4: added new Peers dialog to show information about peers
1254	  (other devices, including APs and stations, etc. in the neighborhood)
1255	* added support for WPS External Registrar functionality (configure APs
1256	  and enroll new devices); can be used with wpa_gui-qt4 Peers dialog
1257	  and wpa_cli commands wps_er_start, wps_er_stop, wps_er_pin,
1258	  wps_er_pbc, wps_er_learn
1259	  (this can also be used with a new 'none' driver wrapper if no
1260	  wireless device or IEEE 802.1X on wired is needed)
1261	* driver_nl80211: multiple updates to provide support for new Linux
1262	  nl80211/mac80211 functionality
1263	* updated management frame protection to use IEEE Std 802.11w-2009
1264	* fixed number of small WPS issues and added workarounds to
1265	  interoperate with common deployed broken implementations
1266	* added support for NFC out-of-band mechanism with WPS
1267	* driver_ndis: fixed wired IEEE 802.1X authentication with PAE group
1268	  address frames
1269	* added preliminary support for IEEE 802.11r RIC processing
1270	* added support for specifying subset of enabled frequencies to scan
1271	  (scan_freq option in the network configuration block); this can speed
1272	  up scanning process considerably if it is known that only a small
1273	  subset of channels is actually used in the network (this is currently
1274	  supported only with -Dnl80211)
1275	* added a workaround for race condition between receiving the
1276	  association event and the following EAPOL-Key
1277	* added background scan and roaming infrastructure to allow
1278	  network-specific optimizations to be used to improve roaming within
1279	  an ESS (same SSID)
1280	* added new DBus interface (fi.w1.wpa_supplicant1)
1281
12822009-01-06 - v0.6.7
1283	* added support for Wi-Fi Protected Setup (WPS)
1284	  (wpa_supplicant can now be configured to act as a WPS Enrollee to
1285	  enroll credentials for a network using PIN and PBC methods; in
1286	  addition, wpa_supplicant can act as a wireless WPS Registrar to
1287	  configure an AP); WPS support can be enabled by adding CONFIG_WPS=y
1288	  into .config and setting the runtime configuration variables in
1289	  wpa_supplicant.conf (see WPS section in the example configuration
1290	  file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to
1291	  manage WPS negotiation; see README-WPS for more details
1292	* added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
1293	* added support for using driver_test over UDP socket
1294	* fixed PEAPv0 Cryptobinding interoperability issue with Windows Server
1295	  2008 NPS; optional cryptobinding is now enabled (again) by default
1296	* fixed PSK editing in wpa_gui
1297	* changed EAP-GPSK to use the IANA assigned EAP method type 51
1298	* added a Windows installer that includes WinPcap and all the needed
1299	  DLLs; in addition, it set up the registry automatically so that user
1300	  will only need start wpa_gui to get prompted to start the wpasvc
1301	  servide and add a new interface if needed through wpa_gui dialog
1302	* updated management frame protection to use IEEE 802.11w/D7.0
1303
13042008-11-23 - v0.6.6
1305	* added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
1306	  (can be used to simulate test SIM/USIM card with a known private key;
1307	  enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
1308	  and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
1309	* added a new network configuration option, wpa_ptk_rekey, that can be
1310	  used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
1311	  against TKIP deficiencies
1312	* added an optional mitigation mechanism for certain attacks against
1313	  TKIP by delaying Michael MIC error reports by a random amount of time
1314	  between 0 and 60 seconds; this can be enabled with a build option
1315	  CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
1316	* fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
1317	  not bytes
1318	* updated OpenSSL code for EAP-FAST to use an updated version of the
1319	  session ticket overriding API that was included into the upstream
1320	  OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
1321	  needed with that version anymore)
1322	* updated userspace MLME instructions to match with the current Linux
1323	  mac80211 implementation; please also note that this can only be used
1324	  with driver_nl80211.c (the old code from driver_wext.c was removed)
1325	* added support (Linux only) for RoboSwitch chipsets (often found in
1326	  consumer grade routers); driver interface 'roboswitch'
1327	* fixed canceling of PMKSA caching when using drivers that generate
1328	  RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
1329	  about
1330
13312008-11-01 - v0.6.5
1332	* added support for SHA-256 as X.509 certificate digest when using the
1333	  internal X.509/TLSv1 implementation
1334	* updated management frame protection to use IEEE 802.11w/D6.0
1335	* added support for using SHA256-based stronger key derivation for WPA2
1336	  (IEEE 802.11w)
1337	* fixed FT (IEEE 802.11r) authentication after a failed association to
1338	  use correct FTIE
1339	* added support for configuring Phase 2 (inner/tunneled) authentication
1340	  method with wpa_gui-qt4
1341
13422008-08-10 - v0.6.4
1343	* added support for EAP Sequences in EAP-FAST Phase 2
1344	* added support for using TNC with EAP-FAST
1345	* added driver_ps3 for the PS3 Linux wireless driver
1346	* added support for optional cryptobinding with PEAPv0
1347	* fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
1348	  allow fallback to full handshake if server rejects PAC-Opaque
1349	* added fragmentation support for EAP-TNC
1350	* added support for parsing PKCS #8 formatted private keys into the
1351	  internal TLS implementation (both PKCS #1 RSA key and PKCS #8
1352	  encapsulated RSA key can now be used)
1353	* added option of using faster, but larger, routines in the internal
1354	  LibTomMath (for internal TLS implementation) to speed up DH and RSA
1355	  calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
1356	* fixed race condition between disassociation event and group key
1357	  handshake to avoid getting stuck in incorrect state [Bug 261]
1358	* fixed opportunistic key caching (proactive_key_caching)
1359
13602008-02-22 - v0.6.3
1361	* removed 'nai' and 'eappsk' network configuration variables that were
1362	  previously used for configuring user identity and key for EAP-PSK,
1363	  EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
1364	  replacement for 'nai' (if old configuration used a separate
1365	  'identity' value, that would now be configured as
1366	  'anonymous_identity'). 'password' field is now used as the
1367	  replacement for 'eappsk' (it can also be set using hexstring to
1368	  present random binary data)
1369	* removed '-w' command line parameter (wait for interface to be added,
1370	  if needed); cleaner way of handling this functionality is to use an
1371	  external mechanism (e.g., hotplug scripts) that start wpa_supplicant
1372	  when an interface is added
1373	* updated FT support to use the latest draft, IEEE 802.11r/D9.0
1374	* added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
1375	  indicating when new scan results become available
1376	* added new ctrl_iface command, BSS, to allow scan results to be
1377	  fetched without hitting the message size limits (this command
1378	  can be used to iterate through the scan results one BSS at the time)
1379	* fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
1380	  attributes in EAP-SIM Start/Response when using fast reauthentication
1381	* fixed EAPOL not to end up in infinite loop when processing dynamic
1382	  WEP keys with IEEE 802.1X
1383	* fixed problems in getting NDIS events from WMI on Windows 2000
1384
13852008-01-01 - v0.6.2
1386	* added support for Makefile builds to include debug-log-to-a-file
1387	  functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
1388	* fixed EAP-SIM and EAP-AKA message parser to validate attribute
1389	  lengths properly to avoid potential crash caused by invalid messages
1390	* added data structure for storing allocated buffers (struct wpabuf);
1391	  this does not affect wpa_supplicant usage, but many of the APIs
1392	  changed and various interfaces (e.g., EAP) is not compatible with old
1393	  versions
1394	* added support for protecting EAP-AKA/Identity messages with
1395	  AT_CHECKCODE (optional feature in RFC 4187)
1396	* added support for protected result indication with AT_RESULT_IND for
1397	  EAP-SIM and EAP-AKA (phase1="result_ind=1")
1398	* added driver_wext workaround for race condition between scanning and
1399	  association with drivers that take very long time to scan all
1400	  channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
1401	  using a longer hardcoded timeout for the scan if the driver supports
1402	  notifications for scan completion (SIOCGIWSCAN event); this helps,
1403	  e.g., in cases where wpa_supplicant and madwifi driver ended up in
1404	  loop where the driver did not even try to associate
1405	* stop EAPOL timer tick when no timers are in use in order to reduce
1406	  power consumption (no need to wake up the process once per second)
1407	  [Bug 237]
1408	* added support for privilege separation (run only minimal part of
1409	  wpa_supplicant functionality as root and rest as unprivileged,
1410	  non-root process); see 'Privilege separation' in README for details;
1411	  this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
1412	  in .config
1413	* changed scan results data structure to include all information
1414	  elements to make it easier to support new IEs; old get_scan_result()
1415	  driver_ops is still supported for backwards compatibility (results
1416	  are converted internally to the new format), but all drivers should
1417	  start using the new get_scan_results2() to make them more likely to
1418	  work with new features
1419	* Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
1420	  application, i.e., it does not require Qt3Support anymore; Windows
1421	  binary of wpa_gui.exe is now from this directory and only requires
1422	  QtCore4.dll and QtGui4.dll libraries
1423	* updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
1424	  available as a separate package to make wpa_gui installation easier:
1425	  http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
1426	* added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
1427	  only shared key/password authentication is supported in this version
1428
14292007-11-24 - v0.6.1
1430	* added support for configuring password as NtPasswordHash
1431	  (16-byte MD4 hash of password) in hash:<32 hex digits> format
1432	* added support for fallback from abbreviated TLS handshake to
1433	  full handshake when using EAP-FAST (e.g., due to an expired
1434	  PAC-Opaque)
1435	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
1436	  draft (draft-ietf-emu-eap-gpsk-07.txt)
1437	* added support for drivers that take care of RSN 4-way handshake
1438	  internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
1439	  WPA_ALG_PMK in set_key)
1440	* added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
1441	  .config); this version supports only ap_scan=2 mode and allow the
1442	  driver to take care of the 4-way handshake
1443	* fixed a buffer overflow in parsing TSF from scan results when using
1444	  driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
1445	  [Bug 232]
1446	* updated FT support to use the latest draft, IEEE 802.11r/D8.0
1447	* fixed an integer overflow issue in the ASN.1 parser used by the
1448	  (experimental) internal TLS implementation to avoid a potential
1449	  buffer read overflow
1450	* fixed a race condition with -W option (wait for a control interface
1451	  monitor before starting) that could have caused the first messages to
1452	  be lost
1453	* added support for processing TNCC-TNCS-Messages to report
1454	  recommendation (allow/none/isolate) when using TNC [Bug 243]
1455
14562007-05-28 - v0.6.0
1457	* added network configuration parameter 'frequency' for setting
1458	  initial channel for IBSS (adhoc) networks
1459	* added experimental IEEE 802.11r/D6.0 support
1460	* updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
1461	* updated EAP-PSK to use the IANA-allocated EAP type 47
1462	* fixed EAP-PAX key derivation
1463	* fixed EAP-PSK bit ordering of the Flags field
1464	* fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
1465	  tunnelled identity request (previously, the identifier from the outer
1466	  method was used, not the tunnelled identifier which could be
1467	  different)
1468	* added support for fragmentation of outer TLS packets during Phase 2
1469	  of EAP-PEAP/TTLS/FAST
1470	* fixed EAP-TTLS AVP parser processing for too short AVP lengths
1471	* added support for EAP-FAST authentication with inner methods that
1472	  generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
1473	  for PAC provisioning)
1474	* added support for authenticated EAP-FAST provisioning
1475	* added support for configuring maximum number of EAP-FAST PACs to
1476	  store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
1477	* added support for storing EAP-FAST PACs in binary format
1478	  (fast_pac_format=binary in phase1 string)
1479	* fixed dbus ctrl_iface to validate message interface before
1480	  dispatching to avoid a possible segfault [Bug 190]
1481	* fixed PeerKey key derivation to use the correct PRF label
1482	* updated Windows binary build to link against OpenSSL 0.9.8d and
1483	  added support for EAP-FAST
1484	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
1485	  draft (draft-ietf-emu-eap-gpsk-04.txt)
1486	* fixed EAP-AKA Notification processing to allow Notification to be
1487	  processed after AKA Challenge response has been sent
1488	* updated to use IEEE 802.11w/D2.0 for management frame protection
1489	  (still experimental)
1490	* fixed EAP-TTLS implementation not to crash on use of freed memory
1491	  if TLS library initialization fails
1492	* added support for EAP-TNC (Trusted Network Connect)
1493	  (this version implements the EAP-TNC method and EAP-TTLS changes
1494	  needed to run two methods in sequence (IF-T) and the IF-IMC and
1495	  IF-TNCCS interfaces from TNCC)
1496
14972006-11-24 - v0.5.6
1498	* added experimental, integrated TLSv1 client implementation with the
1499	  needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
1500	  setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
1501	  .config); this can be useful, e.g., if the target system does not
1502	  have a suitable TLS library and a minimal code size is required
1503	  (total size of this internal TLS/crypto code is bit under 50 kB on
1504	  x86 and the crypto code is shared by rest of the supplicant so some
1505	  of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
1506	* removed STAKey handshake since PeerKey handshake has replaced it in
1507	  IEEE 802.11ma and there are no known deployments of STAKey
1508	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
1509	  draft (draft-ietf-emu-eap-gpsk-01.txt)
1510	* added preliminary implementation of IEEE 802.11w/D1.0 (management
1511	  frame protection)
1512	  (Note: this requires driver support to work properly.)
1513	  (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
1514	* fixed Windows named pipes ctrl_iface to not stop listening for
1515	  commands if client program opens a named pipe and closes it
1516	  immediately without sending a command
1517	* fixed USIM PIN status determination for the case that PIN is not
1518	  needed (this allows EAP-AKA to be used with USIM cards that do not
1519	  use PIN)
1520	* added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
1521	  be used with cards that do not support file selection based on
1522	  partial AID
1523	* added support for matching the subjectAltName of the authentication
1524	  server certificate against multiple name components (e.g.,
1525	  altsubject_match="DNS:server.example.com;DNS:server2.example.com")
1526	* fixed EAP-SIM/AKA key derivation for re-authentication case (only
1527	  affects IEEE 802.1X with dynamic WEP keys)
1528	* changed ctrl_iface network configuration 'get' operations to not
1529	  return password/key material; if these fields are requested, "*"
1530	  will be returned if the password/key is set, but the value of the
1531	  parameter is not exposed
1532
15332006-08-27 - v0.5.5
1534	* added support for building Windows version with UNICODE defined
1535	  (wide-char functions)
1536	* driver_ndis: fixed static WEP configuration to avoid race condition
1537	  issues with some NDIS drivers between association and setting WEP
1538	  keys
1539	* driver_ndis: added validation for IELength value in scan results to
1540	  avoid crashes when using buggy NDIS drivers [Bug 165]
1541	* fixed Release|Win32 target in the Visual Studio project files
1542	  (previously, only Debug|Win32 target was set properly)
1543	* changed control interface API call wpa_ctrl_pending() to allow it to
1544	  return -1 on error (e.g., connection lost); control interface clients
1545	  will need to make sure that they verify that the value is indeed >0
1546	  when determining whether there are pending messages
1547	* added an alternative control interface backend for Windows targets:
1548	  Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
1549	  control interface mechanism for Windows builds (previously, UDP to
1550	  localhost was used)
1551	* changed ctrl_interface configuration for UNIX domain sockets:
1552	  - deprecated ctrl_interface_group variable (it may be removed in
1553	    future versions)
1554	  - allow both directory and group be configured with ctrl_interface
1555	    in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
1556	  - ctrl_interface=/var/run/wpa_supplicant is still supported for the
1557	    case when group is not changed
1558	* added support for controlling more than one interface per process in
1559	  Windows version
1560	* added a workaround for a case where the AP is using unknown address
1561	  (e.g., MAC address of the wired interface) as the source address for
1562	  EAPOL-Key frames; previously, that source address was used as the
1563	  destination for EAPOL-Key frames and in key derivation; now, BSSID is
1564	  used even if the source address does not match with it
1565	  (this resolves an interoperability issue with Thomson SpeedTouch 580)
1566	* added a workaround for UDP-based control interface (which was used in
1567	  Windows builds before this release) to prevent packets with forged
1568	  addresses from being accepted as local control requests
1569	* removed ndis_events.cpp and possibility of using external
1570	  ndis_events.exe; C version (ndis_events.c) is fully functional and
1571	  there is no desire to maintain two separate versions of this
1572	  implementation
1573	* ndis_events: Changed NDIS event notification design to use WMI to
1574	  learn the adapter description through Win32_PnPEntity class; this
1575	  should fix some cases where the adapter name was not recognized
1576	  correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
1577	  USB) [Bug 113]
1578	* fixed selection of the first network in ap_scan=2 mode; previously,
1579	  wpa_supplicant could get stuck in SCANNING state when only the first
1580	  network for enabled (e.g., after 'wpa_cli select_network 0')
1581	* winsvc: added support for configuring ctrl_interface parameters in
1582	  registry (ctrl_interface string value in
1583	  HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
1584	  required to enable control interface (previously, this was hardcoded
1585	  to be enabled)
1586	* allow wpa_gui subdirectory to be built with both Qt3 and Qt4
1587	* converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
1588
15892006-06-20 - v0.5.4
1590	* fixed build with CONFIG_STAKEY=y [Bug 143]
1591	* added support for doing MLME (IEEE 802.11 management frame
1592	  processing) in wpa_supplicant when using Devicescape IEEE 802.11
1593	  stack (wireless-dev.git tree)
1594	* added a new network block configuration option, fragment_size, to
1595	  configure the maximum EAP fragment size
1596	* driver_ndis: Disable WZC automatically for the selected interface to
1597	  avoid conflicts with two programs trying to control the radio; WZC
1598	  will be re-enabled (if it was enabled originally) when wpa_supplicant
1599	  is terminated
1600	* added an experimental TLSv1 client implementation
1601	  (CONFIG_TLS=internal) that can be used instead of an external TLS
1602	  library, e.g., to reduce total size requirement on systems that do
1603	  not include any TLS library by default (this is not yet complete;
1604	  basic functionality is there, but certificate validation is not yet
1605	  included)
1606	* added PeerKey handshake implementation for IEEE 802.11e
1607	  direct link setup (DLS) to replace STAKey handshake
1608	* fixed WPA PSK update through ctrl_iface for the case where the old
1609	  PSK was derived from an ASCII passphrase and the new PSK is set as
1610	  a raw PSK (hex string)
1611	* added new configuration option for identifying which network block
1612	  was used (id_str in wpa_supplicant.conf; included on
1613	  WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
1614	  variable in wpa_cli action scripts; in addition WPA_ID variable is
1615	  set to the current unique identifier that wpa_supplicant assigned
1616	  automatically for the network and that can be used with
1617	  GET_NETWORK/SET_NETWORK ctrl_iface commands)
1618	* wpa_cli action script is now called only when the connect/disconnect
1619	  status changes or when associating with a different network
1620	* fixed configuration parser not to remove CCMP from group cipher list
1621	  if WPA-None (adhoc) is used (pairwise=NONE in that case)
1622	* fixed integrated NDIS events processing not to hang the process due
1623	  to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
1624	* added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
1625	  draft-clancy-emu-eap-shared-secret-00.txt)
1626	* added Microsoft Visual Studio 2005 solution and project files for
1627	  build wpa_supplicant for Windows (see vs2005 subdirectory)
1628	* eloop_win: fixed unregistration of Windows events
1629	* l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
1630	  at the end of RSN pre-authentication and added unregistration of
1631	  a Windows event to avoid getting eloop_win stuck with an invalid
1632	  handle
1633	* driver_ndis: added support for selecting AP based on BSSID
1634	* added new environmental variable for wpa_cli action scripts:
1635	  WPA_CTRL_DIR is the current control interface directory
1636	* driver_ndis: added support for using NDISUIO instead of WinPcap for
1637	  OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
1638	  l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
1639	  wpa_supplicant without requiring WinPcap; note that using NDISUIO
1640	  requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
1641	  only one application to open the device
1642	* changed NDIS driver naming to only include device GUID, e.g.,
1643	  {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
1644	  specific \Device\NPF_ prefix before the GUID; the prefix is still
1645	  allowed for backwards compatibility, but it is not required anymore
1646	  when specifying the interface
1647	* driver_ndis: re-initialize driver interface is the adapter is removed
1648	  and re-inserted [Bug 159]
1649	* driver_madwifi: fixed TKIP and CCMP sequence number configuration on
1650	  big endian hosts [Bug 146]
1651
16522006-04-27 - v0.5.3
1653	* fixed EAP-GTC response to include correct user identity when run as
1654	  phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
1655	* driver_ndis: Fixed encryption mode configuration for unencrypted
1656	  networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
1657	  refused to associate with open networks) [Bug 106]
1658	* driver_ndis: use BSSID OID polling to detect when IBSS network is
1659	  formed even when ndis_events code is included since some NDIS drivers
1660	  do not generate media connect events in IBSS mode
1661	* config_winreg: allow global ctrl_interface parameter to be configured
1662	  in Windows registry
1663	* config_winreg: added support for saving configuration data into
1664	  Windows registry
1665	* added support for controlling network device operational state
1666	  (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
1667	  http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
1668	  that can use this information)
1669	* driver_wext: added support for WE-21 change to SSID configuration
1670	* driver_wext: fixed privacy configuration for static WEP keys mode
1671	  [Bug 140]
1672	* added an optional driver_ops callback for MLME-SETPROTECTION.request
1673	  primitive
1674	* added support for EAP-SAKE (no EAP method number allocated yet, so
1675	  this is using the same experimental type 255 as EAP-PSK)
1676	* added support for dynamically loading EAP methods (.so files) instead
1677	  of requiring them to be statically linked in; this is disabled by
1678	  default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
1679	  on how to use this)
1680
16812006-03-19 - v0.5.2
1682	* do not try to use USIM APDUs when initializing PC/SC for SIM card
1683	  access for a network that has not enabled EAP-AKA
1684	* fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
1685	  v0.5.1 due to the new support for expanded EAP types)
1686	* added support for generating EAP Expanded Nak
1687	* try to fetch scan results once before requesting new scan when
1688	  starting up in ap_scan=1 mode (this can speed up initial association
1689	  a lot with, e.g., madwifi-ng driver)
1690	* added support for receiving EAPOL frames from a Linux bridge
1691	  interface (-bbr0 on command line)
1692	* fixed EAPOL re-authentication for sessions that used PMKSA caching
1693	* changed EAP method registration to use a dynamic list of methods
1694	  instead of a static list generated at build time
1695	* fixed PMKSA cache deinitialization not to use freed memory when
1696	  removing PMKSA entries
1697	* fixed a memory leak in EAP-TTLS re-authentication
1698	* reject WPA/WPA2 message 3/4 if it does not include any valid
1699	  WPA/RSN IE
1700	* driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
1701	  if the driver does not support SIOCSIWAUTH
1702
17032006-01-29 - v0.5.1
1704	* driver_test: added better support for multiple APs and STAs by using
1705	  a directory with sockets that include MAC address for each device in
1706	  the name (driver_param=test_dir=/tmp/test)
1707	* added support for EAP expanded type (vendor specific EAP methods)
1708	* added AP_SCAN command into ctrl_iface so that ap_scan configuration
1709	  option can be changed if needed
1710	* wpa_cli/wpa_gui: skip non-socket files in control directory when
1711	  using UNIX domain sockets; this avoids selecting an incorrect
1712	  interface (e.g., a PID file could be in this directory, even though
1713	  use of this directory for something else than socket files is not
1714	  recommended)
1715	* fixed TLS library deinitialization after RSN pre-authentication not
1716	  to disable TLS library for normal authentication
1717	* driver_wext: Remove null-termination from SSID length if the driver
1718	  used it; some Linux drivers do this and they were causing problems in
1719	  wpa_supplicant not finding matching configuration block. This change
1720	  would break a case where the SSID actually ends in '\0', but that is
1721	  not likely to happen in real use.
1722	* fixed PMKSA cache processing not to trigger deauthentication if the
1723	  current PMKSA cache entry is replaced with a valid new entry
1724	* fixed PC/SC initialization for ap_scan != 1 modes (this fixes
1725	  EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
1726	  ap_scan=2)
1727
17282005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
1729	* added experimental STAKey handshake implementation for IEEE 802.11e
1730	  direct link setup (DLS); note: this is disabled by default in both
1731	  build and runtime configuration (can be enabled with CONFIG_STAKEY=y
1732	  and stakey=1)
1733	* fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
1734	  decrypt AT_ENCR_DATA attributes correctly
1735	* fixed EAP-AKA to allow resynchronization within the same session
1736	* made code closer to ANSI C89 standard to make it easier to port to
1737	  other C libraries and compilers
1738	* started moving operating system or C library specific functions into
1739	  wrapper functions defined in os.h and implemented in os_*.c to make
1740	  code more portable
1741	* wpa_supplicant can now be built with Microsoft Visual C++
1742	  (e.g., with the freely available Toolkit 2003 version or Visual
1743	  C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
1744	  example makefile for nmake
1745	* added support for using Windows registry for command line parameters
1746	  (CONFIG_MAIN=main_winsvc) and configuration data
1747	  (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
1748	  contents; this version can be run both as a Windows service and as a
1749	  normal application; 'wpasvc.exe app' to start as applicant,
1750	  'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
1751	  'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
1752	  unregister a service
1753	* made it possible to link ndis_events.exe functionality into
1754	  wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
1755	* added better support for multiple control interface backends
1756	  (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
1757	* fixed PC/SC code to use correct length for GSM AUTH command buffer
1758	  and to not use pioRecvPci with SCardTransmit() calls; these were not
1759	  causing visible problems with pcsc-lite, but Windows Winscard.dll
1760	  refused the previously used parameters; this fixes EAP-SIM and
1761	  EAP-AKA authentication using SIM/USIM card under Windows
1762	* added new event loop implementation for Windows using
1763	  WaitForMultipleObject() instead of select() in order to allow waiting
1764	  for non-socket objects; this can be selected with
1765	  CONFIG_ELOOP=eloop_win in .config
1766	* added support for selecting l2_packet implementation in .config
1767	  (CONFIG_L2_PACKET; following options are available now: linux, pcap,
1768	  winpcap, freebsd, none)
1769	* added new l2_packet implementation for WinPcap
1770	  (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
1771	  reduce latency in EAPOL receive processing from about 100 ms to about
1772	  3 ms
1773	* added support for EAP-FAST key derivation using other ciphers than
1774	  RC4-128-SHA for authentication and AES128-SHA for provisioning
1775	* added support for configuring CA certificate as DER file and as a
1776	  configuration blob
1777	* fixed private key configuration as configuration blob and added
1778	  support for using PKCS#12 as a blob
1779	* tls_gnutls: added support for using PKCS#12 files; added support for
1780	  session resumption
1781	* added support for loading trusted CA certificates from Windows
1782	  certificate store: ca_cert="cert_store://<name>", where <name> is
1783	  likely CA (Intermediate CA certificates) or ROOT (root certificates)
1784	* added C version of ndis_events.cpp and made it possible to build this
1785	  with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
1786	  easily on cross-compilation builds
1787	* added wpasvc.exe into Windows binary release; this is an alternative
1788	  version of wpa_supplicant.exe with configuration backend using
1789	  Windows registry and with the entry point designed to run as a
1790	  Windows service
1791	* integrated ndis_events.exe functionality into wpa_supplicant.exe and
1792	  wpasvc.exe and removed this additional tool from the Windows binary
1793	  release since it is not needed anymore
1794	* load winscard.dll functions dynamically when building with MinGW
1795	  since MinGW does not yet include winscard library
1796
17972005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
1798	* l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
1799	  and WinPcap to receive frames sent to PAE group address
1800	* disable EAP state machine when IEEE 802.1X authentication is not used
1801	  in order to get rid of bogus "EAP failed" messages
1802	* fixed OpenSSL error reporting to go through all pending errors to
1803	  avoid confusing reports of old errors being reported at later point
1804	  during handshake
1805	* fixed configuration file updating to not write empty variables
1806	  (e.g., proto or key_mgmt) that the file parser would not accept
1807	* fixed ADD_NETWORK ctrl_iface command to use the same default values
1808	  for variables as empty network definitions read from config file
1809	  would get
1810	* fixed EAP state machine to not discard EAP-Failure messages in many
1811	  cases (e.g., during TLS handshake)
1812	* fixed a infinite loop in private key reading if the configured file
1813	  cannot be parsed successfully
1814	* driver_madwifi: added support for madwifi-ng
1815	* wpa_gui: do not display password/PSK field contents
1816	* wpa_gui: added CA certificate configuration
1817	* driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
1818	* driver_ndis: include Beacon IEs in AssocInfo in order to notice if
1819	  the new AP is using different WPA/RSN IE
1820	* use longer timeout for IEEE 802.11 association to avoid problems with
1821	  drivers that may take more than five second to associate
1822
18232005-10-27 - v0.4.6
1824	* allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
1825	  RSN IE, but WPA IE would match with wpa_supplicant configuration
1826	* added support for named configuration blobs in order to avoid having
1827	  to use file system for external files (e.g., certificates);
1828	  variables can be set to "blob://<blob name>" instead of file path to
1829	  use a named blob; supported fields: pac_file, client_cert,
1830	  private_key
1831	* fixed RSN pre-authentication (it was broken in the clean up of WPA
1832	  state machine interface in v0.4.5)
1833	* driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
1834	  sure the driver configures broadcast decryption correctly
1835	* added ca_path (and ca_path2) configuration variables that can be used
1836	  to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
1837	  system-wide trusted CA list
1838	* added support for starting wpa_supplicant without a configuration
1839	  file (-C argument must be used to set ctrl_interface parameter for
1840	  this case; in addition, -p argument can be used to provide
1841	  driver_param; these new arguments can also be used with a
1842	  configuration to override the values from the configuration)
1843	* added global control interface that can be optionally used for adding
1844	  and removing network interfaces dynamically (-g command line argument
1845	  for both wpa_supplicant and wpa_cli) without having to restart
1846	  wpa_supplicant process
1847	* wpa_gui:
1848	  - try to save configuration whenever something is modified
1849	  - added WEP key configuration
1850	  - added possibility to edit the current network configuration
1851	* driver_ndis: fixed driver polling not to increase frequency on each
1852	  received EAPOL frame due to incorrectly cancelled timeout
1853	* added simple configuration file examples (in examples subdirectory)
1854	* fixed driver_wext.c to filter wireless events based on ifindex to
1855	  avoid interfaces receiving events from other interfaces
1856	* delay sending initial EAPOL-Start couple of seconds to speed up
1857	  authentication for the most common case of Authenticator starting
1858	  EAP authentication immediately after association
1859
18602005-09-25 - v0.4.5
1861	* added a workaround for clearing keys with ndiswrapper to allow
1862	  roaming from WPA enabled AP to plaintext one
1863	* added docbook documentation (doc/docbook) that can be used to
1864	  generate, e.g., man pages
1865	* l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
1866	  PF_PACKET in order to prepare for network devices that do not use
1867	  Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
1868	* use receipt of EAPOL-Key frame as a lower layer success indication
1869	  for EAP state machine to allow recovery from dropped EAP-Success
1870	  frame
1871	* cleaned up internal EAPOL frame processing by not including link
1872	  layer (Ethernet) header during WPA and EAPOL/EAP processing; this
1873	  header is added only when transmitted the frame; this makes it easier
1874	  to use wpa_supplicant on link layers that use different header than
1875	  Ethernet
1876	* updated EAP-PSK to use draft 9 by default since this can now be
1877	  tested with hostapd; removed support for draft 3, including
1878	  server_nai configuration option from network blocks
1879	* driver_wired: add PAE address to the multicast address list in order
1880	  to be able to receive EAPOL frames with drivers that do not include
1881	  these multicast addresses by default
1882	* driver_wext: add support for WE-19
1883	* added support for multiple configuration backends (CONFIG_BACKEND
1884	  option); currently, only 'file' is supported (i.e., the format used
1885	  in wpa_supplicant.conf)
1886	* added support for updating configuration ('wpa_cli save_config');
1887	  this is disabled by default and can be enabled with global
1888	  update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
1889	  and wpa_gui to store the configuration changes in a permanent store
1890	* added GET_NETWORK ctrl_iface command
1891	  (e.g., 'wpa_cli get_network 0 ssid')
1892
18932005-08-21 - v0.4.4
1894	* replaced OpenSSL patch for EAP-FAST support
1895	  (openssl-tls-extensions.patch) with a more generic and correct
1896	  patch (the new patch is not compatible with the previous one, so the
1897	  OpenSSL library will need to be patched with the new patch in order
1898	  to be able to build wpa_supplicant with EAP-FAST support)
1899	* added support for using Windows certificate store (through CryptoAPI)
1900	  for client certificate and private key operations (EAP-TLS)
1901	  (see wpa_supplicant.conf for more information on how to configure
1902	  this with private_key)
1903	* ported wpa_gui to Windows
1904	* added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
1905	  built with the open source version of the Qt4 for Windows
1906	* allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
1907	  with drivers that do not support WPA
1908	* ndis_events: fixed Windows 2000 support
1909	* added support for enabling/disabling networks from the list of all
1910	  configured networks ('wpa_cli enable_network <network id>' and
1911	  'wpa_cli disable_network <network id>')
1912	* added support for adding and removing network from the current
1913	  configuration ('wpa_cli add_network' and 'wpa_cli remove_network
1914	  <network id>'); added networks are disabled by default and they can
1915	  be enabled with enable_network command once the configuration is done
1916	  for the new network; note: configuration file is not yet updated, so
1917	  these new networks are lost when wpa_supplicant is restarted
1918	* added support for setting network configuration parameters through
1919	  the control interface, for example:
1920	  wpa_cli set_network 0 ssid "\"my network\""
1921	* fixed parsing of strings that include both " and # within double
1922	  quoted area (e.g., "start"#end")
1923	* added EAP workaround for PEAP session resumption: allow outer,
1924	  i.e., not tunneled, EAP-Success to terminate session since; this can
1925	  be disabled with eap_workaround=0
1926	  (this was allowed for PEAPv1 before, but now it is also allowed for
1927	  PEAPv0 since at least one RADIUS authentication server seems to be
1928	  doing this for PEAPv0, too)
1929	* wpa_gui: added preliminary support for adding new networks to the
1930	  wpa_supplicant configuration (double click on the scan results to
1931	  open network configuration)
1932
19332005-06-26 - v0.4.3
1934	* removed interface for external EAPOL/EAP supplicant (e.g.,
1935	  Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
1936	  anymore and is unlikely to be used by anyone
1937	* driver_ndis: fixed WinPcap 3.0 support
1938	* fixed build with CONFIG_DNET_PCAP=y on Linux
1939	* l2_packet: moved different implementations into separate files
1940	  (l2_packet_*.c)
1941
19422005-06-12 - v0.4.2
1943	* driver_ipw: updated driver structures to match with ipw2200-1.0.4
1944	  (note: ipw2100-1.1.0 is likely to require an update to work with
1945	  this)
1946	* added support for using ap_scan=2 mode with multiple network blocks;
1947	  wpa_supplicant will go through the networks one by one until the
1948	  driver reports a successful association; this uses the same order for
1949	  networks as scan_ssid=1 scans, i.e., the priority field is ignored
1950	  and the network block order in the file is used instead
1951	* fixed a potential issue in RSN pre-authentication ending up using
1952	  freed memory if pre-authentication times out
1953	* added support for matching alternative subject name extensions of the
1954	  authentication server certificate; new configuration variables
1955	  altsubject_match and altsubject_match2
1956	* driver_ndis: added support for IEEE 802.1X authentication with wired
1957	  NDIS drivers
1958	* added support for querying private key password (EAP-TLS) through the
1959	  control interface (wpa_cli/wpa_gui) if one is not included in the
1960	  configuration file
1961	* driver_broadcom: fixed couple of memory leaks in scan result
1962	  processing
1963	* EAP-PAX is now registered as EAP type 46
1964	* fixed EAP-PAX MAC calculation
1965	* fixed EAP-PAX CK and ICK key derivation
1966	* added support for using password with EAP-PAX (as an alternative to
1967	  entering key with eappsk); SHA-1 hash of the password will be used as
1968	  the key in this case
1969	* added support for arbitrary driver interface parameters through the
1970	  configuration file with a new driver_param field; this adds a new
1971	  driver_ops function set_param()
1972	* added possibility to override l2_packet module with driver interface
1973	  API (new send_eapol handler); this can be used to implement driver
1974	  specific TX/RX functions for EAPOL frames
1975	* fixed ctrl_interface_group processing for the case where gid is
1976	  entered as a number, not group name
1977	* driver_test: added support for testing hostapd with wpa_supplicant
1978	  by using test driver interface without any kernel drivers or network
1979	  cards
1980
19812005-05-22 - v0.4.1
1982	* driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
1983	  packets to be encrypted; this was apparently broken by the changed
1984	  ioctl order in v0.4.0
1985	* driver_madwifi: added preliminary support for compiling against 'BSD'
1986	  branch of madwifi CVS tree
1987	* added support for EAP-MSCHAPv2 password retries within the same EAP
1988	  authentication session
1989	* added support for password changes with EAP-MSCHAPv2 (used when the
1990	  password has expired)
1991	* added support for reading additional certificates from PKCS#12 files
1992	  and adding them to the certificate chain
1993	* fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
1994	  were used
1995	* fixed a possible double free in EAP-TTLS fast-reauthentication when
1996	  identity or password is entered through control interface
1997	* display EAP Notification messages to user through control interface
1998	  with "CTRL-EVENT-EAP-NOTIFICATION" prefix
1999	* added GUI version of wpa_cli, wpa_gui; this is not build
2000	  automatically with 'make'; use 'make wpa_gui' to build (this requires
2001	  Qt development tools)
2002	* added 'disconnect' command to control interface for setting
2003	  wpa_supplicant in state where it will not associate before
2004	  'reassociate' command has been used
2005	* added support for selecting a network from the list of all configured
2006	  networks ('wpa_cli select_network <network id>'; this disabled all
2007	  other networks; to re-enable, 'wpa_cli select_network any')
2008	* added support for getting scan results through control interface
2009	* added EAP workaround for PEAPv1 session resumption: allow outer,
2010	  i.e., not tunneled, EAP-Success to terminate session since; this can
2011	  be disabled with eap_workaround=0
2012
20132005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
2014	* added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
2015	  used to reduce the size of the wpa_supplicant considerably if
2016	  debugging code is not needed
2017	* fixed EAPOL-Key validation to drop packets with invalid Key Data
2018	  Length; such frames could have crashed wpa_supplicant due to buffer
2019	  overflow
2020	* added support for wired authentication (IEEE 802.1X on wired
2021	  Ethernet); driver interface 'wired'
2022	* obsoleted set_wpa() handler in the driver interface API (it can be
2023	  replaced by moving enable/disable functionality into init()/deinit())
2024	  (calls to set_wpa() are still present for backwards compatibility,
2025	  but they may be removed in the future)
2026	* driver_madwifi: fixed association in plaintext mode
2027	* modified the EAP workaround that accepts EAP-Success with incorrect
2028	  Identifier to be even less strict about verification in order to
2029	  interoperate with some authentication servers
2030	* added support for sending TLS alerts
2031	* added support for 'any' SSID wildcard; if ssid is not configured or
2032	  is set to an empty string, any SSID will be accepted for non-WPA AP
2033	* added support for asking PIN (for SIM) from frontends (e.g.,
2034	  wpa_cli); if a PIN is needed, but not included in the configuration
2035	  file, a control interface request is sent and EAP processing is
2036	  delayed until the PIN is available
2037	* added support for using external devices (e.g., a smartcard) for
2038	  private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
2039	  new wpa_supplicant.conf variables:
2040	  - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
2041	  - network: engine, engine_id, key_id
2042	* added experimental support for EAP-PAX
2043	* added monitor mode for wpa_cli (-a<path to a program to run>) that
2044	  allows external commands (e.g., shell scripts) to be run based on
2045	  wpa_supplicant events, e.g., when authentication has been completed
2046	  and data connection is ready; other related wpa_cli arguments:
2047	  -B (run in background), -P (write PID file); wpa_supplicant has a new
2048	  command line argument (-W) that can be used to make it wait until a
2049	  control interface command is received in order to avoid missing
2050	  events
2051	* added support for opportunistic WPA2 PMKSA key caching (disabled by
2052	  default, can be enabled with proactive_key_caching=1)
2053	* fixed RSN IE in 4-Way Handshake message 2/4 for the case where
2054	  Authenticator rejects PMKSA caching attempt and the driver is not
2055	  using assoc_info events
2056	* added -P<pid file> argument for wpa_supplicant to write the current
2057	  process id into a file
2058
20592005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
2060	* added new phase1 option parameter, include_tls_length=1, to force
2061	  wpa_supplicant to add TLS Message Length field to all TLS messages
2062	  even if the packet is not fragmented; this may be needed with some
2063	  authentication servers
2064	* fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
2065	  using drivers that take care of AP selection (e.g., when using
2066	  ap_scan=2)
2067	* fixed reprocessing of pending request after ctrl_iface requests for
2068	  identity/password/otp
2069	* fixed ctrl_iface requests for identity/password/otp in Phase 2 of
2070	  EAP-PEAP and EAP-TTLS
2071	* all drivers using driver_wext: set interface up and select Managed
2072	  mode when starting wpa_supplicant; set interface down when exiting
2073	* renamed driver_ipw2100.c to driver_ipw.c since it now supports both
2074	  ipw2100 and ipw2200; please note that this also changed the
2075	  configuration variable in .config to CONFIG_DRIVER_IPW
2076
20772005-01-24 - v0.3.6
2078	* fixed a busy loop introduced in v0.3.5 for scan result processing
2079	  when no matching AP is found
2080
20812005-01-23 - v0.3.5
2082	* added a workaround for an interoperability issue with a Cisco AP
2083	  when using WPA2-PSK
2084	* fixed non-WPA IEEE 802.1X to use the same authentication timeout as
2085	  WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
2086	  retransmission of dropped frames)
2087	* fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
2088	  (e.g., segfault when processing EAPOL-Key frames)
2089	* fixed EAP workaround and fast reauthentication configuration for
2090	  RSN pre-authentication; previously these were disabled and
2091	  pre-authentication would fail if the used authentication server
2092	  requires EAP workarounds
2093	* added support for blacklisting APs that fail or timeout
2094	  authentication in ap_scan=1 mode so that all APs are tried in cases
2095	  where the ones with strongest signal level are failing authentication
2096	* fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
2097	  authentication attempt
2098	* allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
2099	  in the previous authentication (previously, only Phase 1 success was
2100	  verified)
2101
21022005-01-09 - v0.3.4
2103	* added preliminary support for IBSS (ad-hoc) mode configuration
2104	  (mode=1 in network block); this included a new key_mgmt mode
2105	  WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
2106	  key management; see wpa_supplicant.conf for more details and an
2107	  example on how to configure this (note: this is currently implemented
2108	  only for driver_hostapd.c, but the changes should be trivial to add
2109	  in associate() handler for other drivers, too (assuming the driver
2110	  supports WPA-None)
2111	* added preliminary port for native Windows (i.e., no cygwin) using
2112	  mingw
2113
21142005-01-02 - v0.3.3
2115	* added optional support for GNU Readline and History Libraries for
2116	  wpa_cli (CONFIG_READLINE)
2117	* cleaned up EAP state machine <-> method interface and number of
2118	  small problems with error case processing not terminating on
2119	  EAP-Failure but waiting for timeout
2120	* added couple of workarounds for interoperability issues with a
2121	  Cisco AP when using WPA2
2122	* added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
2123	  Note: This requires a patch for openssl to add support for TLS
2124	  extensions and number of workarounds for operations without
2125	  certificates. Proof of concept type of experimental patch is
2126	  included in openssl-tls-extensions.patch.
2127
21282004-12-19 - v0.3.2
2129	* fixed private key loading for cases where passphrase is not set
2130	* fixed Windows/cygwin L2 packet handler freeing; previous version
2131	  could cause a segfault when RSN pre-authentication was completed
2132	* added support for PMKSA caching with drivers that generate RSN IEs
2133	  (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
2134	  but similar code can be easily added to driver_ndiswrapper.c once
2135	  ndiswrapper gets full support for RSN PMKSA caching
2136	* improved recovery from PMKID mismatches by requesting full EAP
2137	  authentication in case of failed PMKSA caching attempt
2138	* driver_ndis: added support for NDIS NdisMIncidateStatus() events
2139	  (this requires that ndis_events is ran while wpa_supplicant is
2140	  running)
2141	* driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
2142	* added support for driver interfaces to replace the interface name
2143	  based on driver/OS specific mapping, e.g., in case of driver_ndis,
2144	  this allows the beginning of the adapter description to be used as
2145	  the interface name
2146	* added support for CR+LF (Windows-style) line ends in configuration
2147	  file
2148	* driver_ndis: enable radio before starting scanning, disable radio
2149	  when exiting
2150	* modified association event handler to set portEnabled = FALSE before
2151	  clearing port Valid in order to reset EAP state machine and avoid
2152	  problems with new authentication getting ignored because of state
2153	  machines ending up in AUTHENTICATED/SUCCESS state based on old
2154	  information
2155	* added support for driver events to add PMKID candidates in order to
2156	  allow drivers to give priority to most likely roaming candidates
2157	* driver_hostap: moved PrivacyInvoked configuration to associate()
2158	  function so that this will not be set for plaintext connections
2159	* added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
2160	  interface can distinguish plaintext and IEEE 802.1X (no WPA)
2161	  authentication
2162	* fixed static WEP key configuration to use broadcast/default type for
2163	  all keys (previously, the default TX key was configured as pairwise/
2164	  unicast key)
2165	* driver_ndis: added legacy WPA capability detection for non-WPA2
2166	  drivers
2167	* added support for setting static WEP keys for IEEE 802.1X without
2168	  dynamic WEP keying (eapol_flags=0)
2169
21702004-12-12 - v0.3.1
2171	* added support for reading PKCS#12 (PFX) files (as a replacement for
2172	  PEM/DER) to get certificate and private key (CONFIG_PKCS12)
2173	* fixed compilation with CONFIG_PCSC=y
2174	* added new ap_scan mode, ap_scan=2, for drivers that take care of
2175	  association, but need to be configured with security policy and SSID,
2176	  e.g., ndiswrapper and NDIS driver; this mode should allow such
2177	  drivers to work with hidden SSIDs and optimized roaming; when
2178	  ap_scan=2 is used, only the first network block in the configuration
2179	  file is used and this configuration should have explicit security
2180	  policy (i.e., only one option in the lists) for key_mgmt, pairwise,
2181	  group, proto variables
2182	* added experimental port of wpa_supplicant for Windows
2183	  - driver_ndis.c driver interface (NDIS OIDs)
2184	  - currently, this requires cygwin and WinPcap
2185	  - small utility, win_if_list, can be used to get interface name
2186	* control interface can now be removed at build time; add
2187	  CONFIG_CTRL_IFACE=y to .config to maintain old functionality
2188	* optional Xsupplicant interface can now be removed at build time;
2189	  (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
2190	* added auth_alg to driver interface associate() parameters to make it
2191	  easier for drivers to configure authentication algorithm as part of
2192	  the association
2193
21942004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
2195	* driver_broadcom: added new driver interface for Broadcom wl.o driver
2196	  (a generic driver for Broadcom IEEE 802.11a/g cards)
2197	* wpa_cli: fixed parsing of -p <path> command line argument
2198	* PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
2199	  ACK, not tunneled EAP-Success (of which only the first byte was
2200	  actually send due to a bug in previous code); this seems to
2201	  interoperate with most RADIUS servers that implements PEAPv1
2202	* PEAPv1: added support for terminating PEAP authentication on tunneled
2203	  EAP-Success message; this can be configured by adding
2204	  peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
2205	  (some RADIUS servers require this whereas others require a tunneled
2206	  reply
2207	* PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
2208	  the old label for key derivation; previously, the default was 1,
2209	  but it looks like most existing PEAPv1 implementations use the old
2210	  label which is thus more suitable default option
2211	* added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
2212	* fixed parsing of wep_tx_keyidx
2213	* added support for configuring list of allowed Phase 2 EAP types
2214	  (for both EAP-PEAP and EAP-TTLS) instead of only one type
2215	* added support for configuring IEEE 802.11 authentication algorithm
2216	  (auth_alg; mainly for using Shared Key authentication with static
2217	  WEP keys)
2218	* added support for EAP-AKA (with UMTS SIM)
2219	* fixed couple of errors in PCSC handling that could have caused
2220	  random-looking errors for EAP-SIM
2221	* added support for EAP-SIM pseudonyms and fast re-authentication
2222	* added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
2223	  session resumption)
2224	* added support for EAP-SIM with two challenges
2225	  (phase1="sim_min_num_chal=3" can be used to require three challenges)
2226	* added support for configuring DH/DSA parameters for an ephemeral DH
2227	  key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
2228	  dh_file and dh_file2 (phase 2); this adds support for using DSA keys
2229	  and optional DH key exchange to achieve forward secracy with RSA keys
2230	* added support for matching subject of the authentication server
2231	  certificate with a substring when using EAP-TLS/PEAP/TTLS; new
2232	  configuration variables subject_match and subject_match2
2233	* changed SSID configuration in driver_wext.c (used by many driver
2234	  interfaces) to use ssid_len+1 as the length for SSID since some Linux
2235	  drivers expect this
2236	* fixed couple of unaligned reads in scan result parsing to fix WPA
2237	  connection on some platforms (e.g., ARM)
2238	* added driver interface for Intel ipw2100 driver
2239	* added support for LEAP with WPA
2240	* added support for larger scan results report (old limit was 4 kB of
2241	  data, i.e., about 35 or so APs) when using Linux wireless extensions
2242	  v17 or newer
2243	* fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
2244	  only if there is a PMKSA cache entry for the current AP
2245	* fixed error handling for case where reading of scan results fails:
2246	  must schedule a new scan or wpa_supplicant will remain waiting
2247	  forever
2248	* changed debug output to remove shared password/key material by
2249	  default; all key information can be included with -K command line
2250	  argument to match the previous behavior
2251	* added support for timestamping debug log messages (disabled by
2252	  default, can be enabled with -t command line argument)
2253	* set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
2254	  if keys are not configured to be used; this fixes IEEE 802.1X mode
2255	  with drivers that use this information to configure whether Privacy
2256	  bit can be in Beacon frames (e.g., ndiswrapper)
2257	* avoid clearing driver keys if no keys have been configured since last
2258	  key clear request; this seems to improve reliability of group key
2259	  handshake for ndiswrapper & NDIS driver which seems to be suffering
2260	  of some kind of timing issue when the keys are cleared again after
2261	  association
2262	* changed driver interface API:
2263	  - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
2264	    version is being used (now, this is set to 2; previously, it was
2265	    not defined)
2266	  - pass pointer to private data structure to all calls
2267	  - the new API is not backwards compatible; all in-tree driver
2268	    interfaces has been converted to the new API
2269	* added support for controlling multiple interfaces (radios) per
2270	  wpa_supplicant process; each interface needs to be listed on the
2271	  command line (-c, -i, -D arguments) with -N as a separator
2272	  (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
2273	* added a workaround for EAP servers that incorrectly use same Id for
2274	  sequential EAP packets
2275	* changed libpcap/libdnet configuration to use .config variable,
2276	  CONFIG_DNET_PCAP, instead of requiring Makefile modification
2277	* improved downgrade attack detection in IE verification of msg 3/4:
2278	  verify both WPA and RSN IEs, if present, not only the selected one;
2279	  reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
2280	  Probe Response frame, and RSN is enabled in wpa_supplicant
2281	  configuration
2282	* fixed WPA msg 3/4 processing to allow Key Data field contain other
2283	  IEs than just one WPA IE
2284	* added support for FreeBSD and driver interface for the BSD net80211
2285	  layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
2286	  required kernel mods have not yet been committed
2287	* made EAP workarounds configurable; enabled by default, can be
2288	  disabled with network block option eap_workaround=0
2289
22902004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
2291	* resolved couple of interoperability issues with EAP-PEAPv1 and
2292	  Phase 2 (inner EAP) fragment reassembly
2293	* driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
2294	  AP is using non-zero key index for the unicast key and key index zero
2295	  for the broadcast key
2296	* driver_hostap: fixed IEEE 802.1X WEP key updates and
2297	  re-authentication by allowing unencrypted EAPOL frames when not using
2298	  WPA
2299	* added a new driver interface, 'wext', which uses only standard,
2300	  driver independent functionality in Linux wireless extensions;
2301	  currently, this can be used only for non-WPA IEEE 802.1X mode, but
2302	  eventually, this is to be extended to support full WPA/WPA2 once
2303	  Linux wireless extensions get support for this
2304	* added support for mode in which the driver is responsible for AP
2305	  scanning and selection; this is disabled by default and can be
2306	  enabled with global ap_scan=0 variable in wpa_supplicant.conf;
2307	  this mode can be used, e.g., with generic 'wext' driver interface to
2308	  use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
2309	  supporting wireless extensions.
2310	* driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
2311	  operation with an AP that does not include SSID in the Beacon frames)
2312	* added support for new EAP authentication methods:
2313	  EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
2314	* added support for asking one-time-passwords from frontends (e.g.,
2315	  wpa_cli); this 'otp' command works otherwise like 'password' command,
2316	  but the password is used only once and the frontend will be asked for
2317	  a new password whenever a request from authenticator requires a
2318	  password; this can be used with both EAP-OTP and EAP-GTC
2319	* changed wpa_cli to automatically re-establish connection so that it
2320	  does not need to be re-started when wpa_supplicant is terminated and
2321	  started again
2322	* improved user data (identity/password/otp) requests through
2323	  frontends: process pending EAPOL packets after getting new
2324	  information so that full authentication does not need to be
2325	  restarted; in addition, send pending requests again whenever a new
2326	  frontend is attached
2327	* changed control frontends to use a new directory for socket files to
2328	  make it easier for wpa_cli to automatically select between interfaces
2329	  and to provide access control for the control interface;
2330	  wpa_supplicant.conf: ctrl_interface is now a path
2331	  (/var/run/wpa_supplicant is the recommended path) and
2332	  ctrl_interface_group can be used to select which group gets access to
2333	  the control interface;
2334	  wpa_cli: by default, try to connect to the first interface available
2335	  in /var/run/wpa_supplicant; this path can be overridden with -p option
2336	  and an interface can be selected with -i option (i.e., in most common
2337	  cases, wpa_cli does not need to get any arguments)
2338	* added support for LEAP
2339	* added driver interface for Linux ndiswrapper
2340	* added priority option for network blocks in the configuration file;
2341	  this allows networks to be grouped based on priority (the scan
2342	  results are searched for matches with network blocks in this order)
2343
23442004-06-20 - v0.2.3
2345	* sort scan results to improve AP selection
2346	* fixed control interface socket removal for some error cases
2347	* improved scan requesting and authentication timeout
2348	* small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
2349	  TLS processing
2350	* PEAP version can now be forced with phase1="peapver=<ver>"
2351	  (mostly for testing; by default, the highest version supported by
2352	  both the Supplicant and Authentication Server is selected
2353	  automatically)
2354	* added support for madwifi driver (Atheros ar521x)
2355	* added a workaround for cases where AP sets Install Tx/Rx bit for
2356	  WPA Group Key messages when pairwise keys are used (without this,
2357	  the Group Key would be used for Tx and the AP would drop frames
2358	  from the station)
2359	* added GSM SIM/USIM interface for GSM authentication algorithm for
2360	  EAP-SIM; this requires pcsc-lite
2361	* added support for ATMEL AT76C5XXx driver
2362	* fixed IEEE 802.1X WEP key derivation in the case where Authenticator
2363	  does not include key data in the EAPOL-Key frame (i.e., part of
2364	  EAP keying material is used as data encryption key)
2365	* added support for using plaintext and static WEP networks
2366	  (key_mgmt=NONE)
2367
23682004-05-31 - v0.2.2
2369	* added support for new EAP authentication methods:
2370	  EAP-TTLS/EAP-MD5-Challenge
2371	  EAP-TTLS/EAP-GTC
2372	  EAP-TTLS/EAP-MSCHAPv2
2373	  EAP-TTLS/EAP-TLS
2374	  EAP-TTLS/MSCHAPv2
2375	  EAP-TTLS/MSCHAP
2376	  EAP-TTLS/PAP
2377	  EAP-TTLS/CHAP
2378	  EAP-PEAP/TLS
2379	  EAP-PEAP/GTC
2380	  EAP-PEAP/MD5-Challenge
2381	  EAP-GTC
2382	  EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
2383	* added support for anonymous identity (to be used when identity is
2384	  sent in plaintext; real identity will be used within TLS protected
2385	  tunnel (e.g., with EAP-TTLS)
2386	* added event messages from wpa_supplicant to frontends, e.g., wpa_cli
2387	* added support for requesting identity and password information using
2388	  control interface; in other words, the password for EAP-PEAP or
2389	  EAP-TTLS does not need to be included in the configuration file since
2390	  a frontand (e.g., wpa_cli) can ask it from the user
2391	* improved RSN pre-authentication to use a candidate list and process
2392	  all candidates from each scan; not only one per scan
2393	* fixed RSN IE and WPA IE capabilities field parsing
2394	* ignore Tx bit in GTK IE when Pairwise keys are used
2395	* avoid making new scan requests during IEEE 802.1X negotiation
2396	* use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
2397	  with TLS support (this replaces the included implementation with
2398	  library code to save about 8 kB since the library code is needed
2399	  anyway for TLS)
2400	* fixed WPA-PSK only mode when compiled without IEEE 802.1X support
2401	  (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
2402
24032004-05-06 - v0.2.1
2404	* added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
2405	  Supplicant
2406	  - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
2407	  - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
2408	  - EAP-MD5 (cannot be used with WPA-RADIUS)
2409	    [draft-ietf-eap-rfc2284bis-09.txt]
2410	  - EAP-TLS [RFC 2716]
2411	  - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
2412	  - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
2413	    [draft-kamath-pppext-eap-mschapv2-00.txt]
2414	    (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
2415	    default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
2416	  - new configuration file options: eap, identity, password, ca_cert,
2417	    client_cert, privatekey, private_key_passwd
2418	  - Xsupplicant is not required anymore, but it can be used by
2419	    disabling the internal IEEE 802.1X Supplicant with -e command line
2420	    option
2421	  - this code is not included in the default build; Makefile need to
2422	    be edited for this (uncomment lines for selected functionality)
2423	  - EAP-TLS and EAP-PEAP require openssl libraries
2424	* use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
2425	* added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
2426	  (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
2427	   EAPOL-Key frames instead of WPA key handshakes)
2428	* added support for IEEE 802.11i/RSN (WPA2)
2429	  - improved PTK Key Handshake
2430	  - PMKSA caching, pre-authentication
2431	* fixed wpa_supplicant to ignore possible extra data after WPA
2432	  EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
2433	  TPTK' error from message 3 of 4-Way Handshake in case the AP
2434	  includes extra data after the EAPOL-Key)
2435	* added interface for external programs (frontends) to control
2436	  wpa_supplicant
2437	  - CLI example (wpa_cli) with interactive mode and command line
2438	    mode
2439	  - replaced SIGUSR1 status/statistics with the new control interface
2440	* made some feature compile time configurable
2441	  - .config file for make
2442	  - driver interfaces (hostap, hermes, ..)
2443	  - EAPOL/EAP functions
2444
24452004-02-15 - v0.2.0
2446	* Initial version of wpa_supplicant
