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 1003 pre-authentication with nl80211 interface and drivers that handle 1004 roaming internally. 1005 * dbus: 1006 - Add a DBus signal for EAP SM requests, emitted on the Interface 1007 object. 1008 - Export max scan ssids supported by the driver as MaxScanSSID. 1009 - Add signal Certification for information about server certification. 1010 - Add BSSExpireAge and BSSExpireCount interface properties and 1011 support set/get, which allows for setting BSS cache expiration age 1012 and expiration scan count. 1013 - Add ConfigFile to AddInterface properties. 1014 - Add Interface.Country property and support to get/set the value. 1015 - Add DBus property CurrentAuthMode. 1016 - P2P DBus API added. 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.

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. 1062 * Add blacklist command, allowing an external program to 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. 1070 - Add mechanism for indicating non-standard WPS errors. 1071 - Add CONFIG_WPS_REG_DISABLE_OPEN=y option to disable open networks 1072 by default. 1073 - Add wps_ap_pin cli command for wpa_supplicant AP mode. 1074 - Add wps_check_pin cli command for processing PIN from user input. 1075 UIs can use this command to process a PIN entered by a user and to 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.

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) 1110 - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool 1111 for testing protocol extensibility. 1112 - Add build option CONFIG_WPS_STRICT to allow disabling of WPS 1113 workarounds. 1114 - Add support for AuthorizedMACs attribute. 1115 * TDLS: 1116 - Propogate 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. 1126 - Add support for TDLS 802.11z. 1127 * wlantest: Add a tool wlantest for IEEE802.11 protocol testing. 1128 wlantest can be used to capture frames from a monitor interface 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).

See README-P2P for more information. 1152 * Many bugfixes. 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 challanges 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 overriden 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 2447
