Slow down attacks on 988 failures up to 10. 989 - Allow AP to start in Enrollee mode without AP PIN for probing, to 990 be compatible with Windows 7. 991 - Add Config Error into WPS-FAIL events to provide more info to the 992 user on how to resolve the issue. 993 - Label and Display config methods are not allowed to be enabled 994 at the same time, since it is unclear which PIN to use if both 995 methods are advertised. 996 - When controlling multiple interfaces: 997 - apply WPS commands to all interfaces configured to use WPS 998 - apply WPS config changes to all interfaces that use WPS 999 - when an attack is detected on any interface, disable AP PIN on 1000 all interfaces 1001 * WPS ER: 1002 - Add special AP Setup Locked mode to allow read only ER. 1003 ap_setup_locked=2 can now be used to enable a special mode where 1004 WPS ER can learn the current AP settings, but cannot change them. 1005 - Show SetSelectedRegistrar events as ctrl_iface events 1006 - Add wps_er_set_config to enroll a network based on a local 1007 network configuration block instead of having to (re-)learn the 1008 current AP settings with wps_er_learn. 1009 - Allow AP filtering based on IP address, add ctrl_iface event for 1010 learned AP settings, add wps_er_config command to configure an AP. 1011 * WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2) 1012 - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool 1013 for testing protocol extensibility. 1014 - Add build option CONFIG_WPS_STRICT to allow disabling of WPS 1015 workarounds. 1016 - Add support for AuthorizedMACs attribute. 1017 * TDLS: 1018 - Propogate TDLS related nl80211 capability flags from kernel and 1019 add them as driver capability flags. If the driver doesn't support 1020 capabilities, assume TDLS is supported internally. When TDLS is 1021 explicitly not supported, disable all user facing TDLS operations. 1022 - Allow TDLS to be disabled at runtime (mostly for testing). 1023 Use set tdls_disabled. 1024 - Honor AP TDLS settings that prohibit/allow TDLS. 1025 - Add a special testing feature for changing TDLS behavior. Use 1026 CONFIG_TDLS_TESTING build param to enable. Configure at runtime 1027 with tdls_testing cli command. 1028 - Add support for TDLS 802.11z. 1029 * wlantest: Add a tool wlantest for IEEE802.11 protocol testing. 1030 wlantest can be used to capture frames from a monitor interface 1031 for realtime capturing or from pcap files for offline analysis. 1032 * Interworking: Support added for 802.11u. Enable in .config with 1033 CONFIG_INTERWORKING. See wpa_supplicant.conf for config parameters 1034 for interworking. wpa_cli commands added to support this are 1035 interworking_select, interworking_connect, anqp_get, fetch_anqp, 1036 and stop_fetch_anqp. 1037 * Android: Add build and runtime support for Android wpa_supplicant. 1038 * bgscan learn: Add new bgscan that learns BSS information based on 1039 previous scans, and uses that information to dynamically generate 1040 the list of channels for background scans. 1041 * Add a new debug message level for excessive information. Use 1042 -ddd to enable. 1043 * TLS: Add support for tls_disable_time_checks=1 in client mode. 1044 * Internal TLS: 1045 - Add support for TLS v1.1 (RFC 4346). Enable with build parameter 1046 CONFIG_TLSV11. 1047 - Add domainComponent parser for X.509 names. 1048 * Linux: Add RFKill support by adding an interface state "disabled". 1049 * Reorder some IEs to get closer to IEEE 802.11 standard. Move 1050 WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames. 1051 Move HT IEs to be later in (Re)Assoc Resp. 1052 * Solaris: Add support for wired 802.1X client. 1053 * Wi-Fi Direct support. See README-P2P for more information. 1054 * Many bugfixes. 1055 1056 2010-04-18 - v0.7.2 1057 * nl80211: fixed number of issues with roaming 1058 * avoid unnecessary roaming if multiple APs with similar signal 1059 strength are present in scan results 1060 * add TLS client events and server probing to ease design of 1061 automatic detection of EAP parameters 1062 * add option for server certificate matching (SHA256 hash of the 1063 certificate) instead of trusted CA certificate configuration 1064 * bsd: Cleaned up driver wrapper and added various low-level 1065 configuration options 1066 * wpa_gui-qt4: do not show too frequent WPS AP available events as 1067 tray messages 1068 * TNC: fixed issues with fragmentation 1069 * EAP-TNC: add Flags field into fragment acknowledgement (needed to 1070 interoperate with other implementations; may potentially breaks 1071 compatibility with older wpa_supplicant/hostapd versions) 1072 * wpa_cli: added option for using a separate process to receive event 1073 messages to reduce latency in showing these 1074 (CFLAGS += -DCONFIG_WPA_CLI_FORK=y in .config to enable this) 1075 * maximum BSS table size can now be configured (bss_max_count) 1076 * BSSes to be included in the BSS table can be filtered based on 1077 configured SSIDs to save memory (filter_ssids) 1078 * fix number of issues with IEEE 802.11r/FT; this version is not 1079 backwards compatible with old versions 1080 * nl80211: add support for IEEE 802.11r/FT protocol (both over-the-air 1081 and over-the-DS) 1082 * add freq_list network configuration parameter to allow the AP 1083 selection to filter out entries based on the operating channel 1084 * add signal strength change events for bgscan; this allows more 1085 dynamic changes to background scanning interval based on changes in 1086 the signal strength with the current AP; this improves roaming within 1087 ESS quite a bit, e.g., with bgscan="simple:30:-45:300" in the network 1088 configuration block to request background scans less frequently when 1089 signal strength remains good and to automatically trigger background 1090 scans whenever signal strength drops noticeably 1091 (this is currently only available with nl80211) 1092 * add BSSID and reason code (if available) to disconnect event messages 1093 * wpa_gui-qt4: more complete support for translating the GUI with 1094 linguist and add German translation 1095 * fix DH padding with internal crypto code (mainly, for WPS) 1096 * do not trigger initial scan automatically anymore if there are no 1097 enabled networks 1098 1099 2010-01-16 - v0.7.1 1100 * cleaned up driver wrapper API (struct wpa_driver_ops); the new API 1101 is not fully backwards compatible, so out-of-tree driver wrappers 1102 will need modifications 1103 * cleaned up various module interfaces 1104 * merge hostapd and wpa_supplicant developers' documentation into a 1105 single document 1106 * nl80211: use explicit deauthentication to clear cfg80211 state to 1107 avoid issues when roaming between APs 1108 * dbus: major design changes in the new D-Bus API 1109 (fi.w1.wpa_supplicant1) 1110 * nl80211: added support for IBSS networks 1111 * added internal debugging mechanism with backtrace support and memory 1112 allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y) 1113 * added WPS ER unsubscription command to more cleanly unregister from 1114 receiving UPnP events when ER is terminated 1115 * cleaned up AP mode operations to avoid need for virtual driver_ops 1116 wrapper 1117 * added BSS table to maintain more complete scan result information 1118 over multiple scans (that may include only partial results) 1119 * wpa_gui-qt4: update Peers dialog information more dynamically while 1120 the dialog is kept open 1121 * fixed PKCS#12 use with OpenSSL 1.0.0 1122 * driver_wext: Added cfg80211-specific optimization to avoid some 1123 unnecessary scans and to speed up association 1124 1125 2009-11-21 - v0.7.0 1126 * increased wpa_cli ping interval to 5 seconds and made this 1127 configurable with a new command line options (-G<seconds>) 1128 * fixed scan buffer processing with WEXT to handle up to 65535 1129 byte result buffer (previously, limited to 32768 bytes) 1130 * allow multiple driver wrappers to be specified on command line 1131 (e.g., -Dnl80211,wext); the first one that is able to initialize the 1132 interface will be used 1133 * added support for multiple SSIDs per scan request to optimize 1134 scan_ssid=1 operations in ap_scan=1 mode (i.e., search for hidden 1135 SSIDs); this requires driver support and can currently be used only 1136 with nl80211 1137 * added support for WPS USBA out-of-band mechanism with USB Flash 1138 Drives (UFD) (CONFIG_WPS_UFD=y) 1139 * driver_ndis: add PAE group address to the multicast address list to 1140 fix wired IEEE 802.1X authentication 1141 * fixed IEEE 802.11r key derivation function to match with the standard 1142 (note: this breaks interoperability with previous version) [Bug 303] 1143 * added better support for drivers that allow separate authentication 1144 and association commands (e.g., mac80211-based Linux drivers with 1145 nl80211; SME in wpa_supplicant); this allows over-the-air FT protocol 1146 to be used (IEEE 802.11r) 1147 * fixed SHA-256 based key derivation function to match with the 1148 standard when using CCMP (for IEEE 802.11r and IEEE 802.11w) 1149 (note: this breaks interoperability with previous version) [Bug 307] 1150 * use shared driver wrapper files with hostapd 1151 * added AP mode functionality (CONFIG_AP=y) with mode=2 in the network 1152 block; this can be used for open and WPA2-Personal networks 1153 (optionally, with WPS); this links in parts of hostapd functionality 1154 into wpa_supplicant 1155 * wpa_gui-qt4: added new Peers dialog to show information about peers 1156 (other devices, including APs and stations, etc. in the neighborhood) 1157 * added support for WPS External Registrar functionality (configure APs 1158 and enroll new devices); can be used with wpa_gui-qt4 Peers dialog 1159 and wpa_cli commands wps_er_start, wps_er_stop, wps_er_pin, 1160 wps_er_pbc, wps_er_learn 1161 (this can also be used with a new 'none' driver wrapper if no 1162 wireless device or IEEE 802.1X on wired is needed) 1163 * driver_nl80211: multiple updates to provide support for new Linux 1164 nl80211/mac80211 functionality 1165 * updated management frame protection to use IEEE Std 802.11w-2009 1166 * fixed number of small WPS issues and added workarounds to 1167 interoperate with common deployed broken implementations 1168 * added support for NFC out-of-band mechanism with WPS 1169 * driver_ndis: fixed wired IEEE 802.1X authentication with PAE group 1170 address frames 1171 * added preliminary support for IEEE 802.11r RIC processing 1172 * added support for specifying subset of enabled frequencies to scan 1173 (scan_freq option in the network configuration block); this can speed 1174 up scanning process considerably if it is known that only a small 1175 subset of channels is actually used in the network (this is currently 1176 supported only with -Dnl80211) 1177 * added a workaround for race condition between receiving the 1178 association event and the following EAPOL-Key 1179 * added background scan and roaming infrastructure to allow 1180 network-specific optimizations to be used to improve roaming within 1181 an ESS (same SSID) 1182 * added new DBus interface (fi.w1.wpa_supplicant1) 1183 1184 2009-01-06 - v0.6.7 1185 * added support for Wi-Fi Protected Setup (WPS) 1186 (wpa_supplicant can now be configured to act as a WPS Enrollee to 1187 enroll credentials for a network using PIN and PBC methods; in 1188 addition, wpa_supplicant can act as a wireless WPS Registrar to 1189 configure an AP); WPS support can be enabled by adding CONFIG_WPS=y 1190 into .config and setting the runtime configuration variables in 1191 wpa_supplicant.conf (see WPS section in the example configuration 1192 file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to 1193 manage WPS negotiation; see README-WPS for more details 1194 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf) 1195 * added support for using driver_test over UDP socket 1196 * fixed PEAPv0 Cryptobinding interoperability issue with Windows Server 1197 2008 NPS; optional cryptobinding is now enabled (again) by default 1198 * fixed PSK editing in wpa_gui 1199 * changed EAP-GPSK to use the IANA assigned EAP method type 51 1200 * added a Windows installer that includes WinPcap and all the needed 1201 DLLs; in addition, it set up the registry automatically so that user 1202 will only need start wpa_gui to get prompted to start the wpasvc 1203 servide and add a new interface if needed through wpa_gui dialog 1204 * updated management frame protection to use IEEE 802.11w/D7.0 1205 1206 2008-11-23 - v0.6.6 1207 * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA 1208 (can be used to simulate test SIM/USIM card with a known private key; 1209 enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config 1210 and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration) 1211 * added a new network configuration option, wpa_ptk_rekey, that can be 1212 used to enforce frequent PTK rekeying, e.g., to mitigate some attacks 1213 against TKIP deficiencies 1214 * added an optional mitigation mechanism for certain attacks against 1215 TKIP by delaying Michael MIC error reports by a random amount of time 1216 between 0 and 60 seconds; this can be enabled with a build option 1217 CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config 1218 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits, 1219 not bytes 1220 * updated OpenSSL code for EAP-FAST to use an updated version of the 1221 session ticket overriding API that was included into the upstream 1222 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is 1223 needed with that version anymore) 1224 * updated userspace MLME instructions to match with the current Linux 1225 mac80211 implementation; please also note that this can only be used 1226 with driver_nl80211.c (the old code from driver_wext.c was removed) 1227 * added support (Linux only) for RoboSwitch chipsets (often found in 1228 consumer grade routers); driver interface 'roboswitch' 1229 * fixed canceling of PMKSA caching when using drivers that generate 1230 RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know 1231 about 1232 1233 2008-11-01 - v0.6.5 1234 * added support for SHA-256 as X.509 certificate digest when using the 1235 internal X.509/TLSv1 implementation 1236 * updated management frame protection to use IEEE 802.11w/D6.0 1237 * added support for using SHA256-based stronger key derivation for WPA2 1238 (IEEE 802.11w) 1239 * fixed FT (IEEE 802.11r) authentication after a failed association to 1240 use correct FTIE 1241 * added support for configuring Phase 2 (inner/tunneled) authentication 1242 method with wpa_gui-qt4 1243 1244 2008-08-10 - v0.6.4 1245 * added support for EAP Sequences in EAP-FAST Phase 2 1246 * added support for using TNC with EAP-FAST 1247 * added driver_ps3 for the PS3 Linux wireless driver 1248 * added support for optional cryptobinding with PEAPv0 1249 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to 1250 allow fallback to full handshake if server rejects PAC-Opaque 1251 * added fragmentation support for EAP-TNC 1252 * added support for parsing PKCS #8 formatted private keys into the 1253 internal TLS implementation (both PKCS #1 RSA key and PKCS #8 1254 encapsulated RSA key can now be used) 1255 * added option of using faster, but larger, routines in the internal 1256 LibTomMath (for internal TLS implementation) to speed up DH and RSA 1257 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y) 1258 * fixed race condition between disassociation event and group key 1259 handshake to avoid getting stuck in incorrect state [Bug 261] 1260 * fixed opportunistic key caching (proactive_key_caching) 1261 1262 2008-02-22 - v0.6.3 1263 * removed 'nai' and 'eappsk' network configuration variables that were 1264 previously used for configuring user identity and key for EAP-PSK, 1265 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the 1266 replacement for 'nai' (if old configuration used a separate 1267 'identity' value, that would now be configured as 1268 'anonymous_identity'). 'password' field is now used as the 1269 replacement for 'eappsk' (it can also be set using hexstring to 1270 present random binary data) 1271 * removed '-w' command line parameter (wait for interface to be added, 1272 if needed); cleaner way of handling this functionality is to use an 1273 external mechanism (e.g., hotplug scripts) that start wpa_supplicant 1274 when an interface is added 1275 * updated FT support to use the latest draft, IEEE 802.11r/D9.0 1276 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for 1277 indicating when new scan results become available 1278 * added new ctrl_iface command, BSS, to allow scan results to be 1279 fetched without hitting the message size limits (this command 1280 can be used to iterate through the scan results one BSS at the time) 1281 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION 1282 attributes in EAP-SIM Start/Response when using fast reauthentication 1283 * fixed EAPOL not to end up in infinite loop when processing dynamic 1284 WEP keys with IEEE 802.1X 1285 * fixed problems in getting NDIS events from WMI on Windows 2000 1286 1287 2008-01-01 - v0.6.2 1288 * added support for Makefile builds to include debug-log-to-a-file 1289 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line) 1290 * fixed EAP-SIM and EAP-AKA message parser to validate attribute 1291 lengths properly to avoid potential crash caused by invalid messages 1292 * added data structure for storing allocated buffers (struct wpabuf); 1293 this does not affect wpa_supplicant usage, but many of the APIs 1294 changed and various interfaces (e.g., EAP) is not compatible with old 1295 versions 1296 * added support for protecting EAP-AKA/Identity messages with 1297 AT_CHECKCODE (optional feature in RFC 4187) 1298 * added support for protected result indication with AT_RESULT_IND for 1299 EAP-SIM and EAP-AKA (phase1="result_ind=1") 1300 * added driver_wext workaround for race condition between scanning and 1301 association with drivers that take very long time to scan all 1302 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now 1303 using a longer hardcoded timeout for the scan if the driver supports 1304 notifications for scan completion (SIOCGIWSCAN event); this helps, 1305 e.g., in cases where wpa_supplicant and madwifi driver ended up in 1306 loop where the driver did not even try to associate 1307 * stop EAPOL timer tick when no timers are in use in order to reduce 1308 power consumption (no need to wake up the process once per second) 1309 [Bug 237] 1310 * added support for privilege separation (run only minimal part of 1311 wpa_supplicant functionality as root and rest as unprivileged, 1312 non-root process); see 'Privilege separation' in README for details; 1313 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y 1314 in .config 1315 * changed scan results data structure to include all information 1316 elements to make it easier to support new IEs; old get_scan_result() 1317 driver_ops is still supported for backwards compatibility (results 1318 are converted internally to the new format), but all drivers should 1319 start using the new get_scan_results2() to make them more likely to 1320 work with new features 1321 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4 1322 application, i.e., it does not require Qt3Support anymore; Windows 1323 binary of wpa_gui.exe is now from this directory and only requires 1324 QtCore4.dll and QtGui4.dll libraries 1325 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs 1326 available as a separate package to make wpa_gui installation easier: 1327 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip 1328 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt); 1329 only shared key/password authentication is supported in this version 1330 1331 2007-11-24 - v0.6.1 1332 * added support for configuring password as NtPasswordHash 1333 (16-byte MD4 hash of password) in hash:<32 hex digits> format 1334 * added support for fallback from abbreviated TLS handshake to 1335 full handshake when using EAP-FAST (e.g., due to an expired 1336 PAC-Opaque) 1337 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 1338 draft (draft-ietf-emu-eap-gpsk-07.txt) 1339 * added support for drivers that take care of RSN 4-way handshake 1340 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and 1341 WPA_ALG_PMK in set_key) 1342 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in 1343 .config); this version supports only ap_scan=2 mode and allow the 1344 driver to take care of the 4-way handshake 1345 * fixed a buffer overflow in parsing TSF from scan results when using 1346 driver_wext.c with a driver that includes the TSF (e.g., iwl4965) 1347 [Bug 232] 1348 * updated FT support to use the latest draft, IEEE 802.11r/D8.0 1349 * fixed an integer overflow issue in the ASN.1 parser used by the 1350 (experimental) internal TLS implementation to avoid a potential 1351 buffer read overflow 1352 * fixed a race condition with -W option (wait for a control interface 1353 monitor before starting) that could have caused the first messages to 1354 be lost 1355 * added support for processing TNCC-TNCS-Messages to report 1356 recommendation (allow/none/isolate) when using TNC [Bug 243] 1357 1358 2007-05-28 - v0.6.0 1359 * added network configuration parameter 'frequency' for setting 1360 initial channel for IBSS (adhoc) networks 1361 * added experimental IEEE 802.11r/D6.0 support 1362 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48 1363 * updated EAP-PSK to use the IANA-allocated EAP type 47 1364 * fixed EAP-PAX key derivation 1365 * fixed EAP-PSK bit ordering of the Flags field 1366 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in 1367 tunnelled identity request (previously, the identifier from the outer 1368 method was used, not the tunnelled identifier which could be 1369 different) 1370 * added support for fragmentation of outer TLS packets during Phase 2 1371 of EAP-PEAP/TTLS/FAST 1372 * fixed EAP-TTLS AVP parser processing for too short AVP lengths 1373 * added support for EAP-FAST authentication with inner methods that 1374 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported 1375 for PAC provisioning) 1376 * added support for authenticated EAP-FAST provisioning 1377 * added support for configuring maximum number of EAP-FAST PACs to 1378 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string) 1379 * added support for storing EAP-FAST PACs in binary format 1380 (fast_pac_format=binary in phase1 string) 1381 * fixed dbus ctrl_iface to validate message interface before 1382 dispatching to avoid a possible segfault [Bug 190] 1383 * fixed PeerKey key derivation to use the correct PRF label 1384 * updated Windows binary build to link against OpenSSL 0.9.8d and 1385 added support for EAP-FAST 1386 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 1387 draft (draft-ietf-emu-eap-gpsk-04.txt) 1388 * fixed EAP-AKA Notification processing to allow Notification to be 1389 processed after AKA Challenge response has been sent 1390 * updated to use IEEE 802.11w/D2.0 for management frame protection 1391 (still experimental) 1392 * fixed EAP-TTLS implementation not to crash on use of freed memory 1393 if TLS library initialization fails 1394 * added support for EAP-TNC (Trusted Network Connect) 1395 (this version implements the EAP-TNC method and EAP-TTLS changes 1396 needed to run two methods in sequence (IF-T) and the IF-IMC and 1397 IF-TNCCS interfaces from TNCC) 1398 1399 2006-11-24 - v0.5.6 1400 * added experimental, integrated TLSv1 client implementation with the 1401 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by 1402 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in 1403 .config); this can be useful, e.g., if the target system does not 1404 have a suitable TLS library and a minimal code size is required 1405 (total size of this internal TLS/crypto code is bit under 50 kB on 1406 x86 and the crypto code is shared by rest of the supplicant so some 1407 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB) 1408 * removed STAKey handshake since PeerKey handshake has replaced it in 1409 IEEE 802.11ma and there are no known deployments of STAKey 1410 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 1411 draft (draft-ietf-emu-eap-gpsk-01.txt) 1412 * added preliminary implementation of IEEE 802.11w/D1.0 (management 1413 frame protection) 1414 (Note: this requires driver support to work properly.) 1415 (Note2: IEEE 802.11w is an unapproved draft and subject to change.) 1416 * fixed Windows named pipes ctrl_iface to not stop listening for 1417 commands if client program opens a named pipe and closes it 1418 immediately without sending a command 1419 * fixed USIM PIN status determination for the case that PIN is not 1420 needed (this allows EAP-AKA to be used with USIM cards that do not 1421 use PIN) 1422 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to 1423 be used with cards that do not support file selection based on 1424 partial AID 1425 * added support for matching the subjectAltName of the authentication 1426 server certificate against multiple name components (e.g., 1427 altsubject_match="DNS:server.example.com;DNS:server2.example.com") 1428 * fixed EAP-SIM/AKA key derivation for re-authentication case (only 1429 affects IEEE 802.1X with dynamic WEP keys) 1430 * changed ctrl_iface network configuration 'get' operations to not 1431 return password/key material; if these fields are requested, "*" 1432 will be returned if the password/key is set, but the value of the 1433 parameter is not exposed 1434 1435 2006-08-27 - v0.5.5 1436 * added support for building Windows version with UNICODE defined 1437 (wide-char functions) 1438 * driver_ndis: fixed static WEP configuration to avoid race condition 1439 issues with some NDIS drivers between association and setting WEP 1440 keys 1441 * driver_ndis: added validation for IELength value in scan results to 1442 avoid crashes when using buggy NDIS drivers [Bug 165] 1443 * fixed Release|Win32 target in the Visual Studio project files 1444 (previously, only Debug|Win32 target was set properly) 1445 * changed control interface API call wpa_ctrl_pending() to allow it to 1446 return -1 on error (e.g., connection lost); control interface clients 1447 will need to make sure that they verify that the value is indeed >0 1448 when determining whether there are pending messages 1449 * added an alternative control interface backend for Windows targets: 1450 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default 1451 control interface mechanism for Windows builds (previously, UDP to 1452 localhost was used) 1453 * changed ctrl_interface configuration for UNIX domain sockets: 1454 - deprecated ctrl_interface_group variable (it may be removed in 1455 future versions) 1456 - allow both directory and group be configured with ctrl_interface 1457 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel 1458 - ctrl_interface=/var/run/wpa_supplicant is still supported for the 1459 case when group is not changed 1460 * added support for controlling more than one interface per process in 1461 Windows version 1462 * added a workaround for a case where the AP is using unknown address 1463 (e.g., MAC address of the wired interface) as the source address for 1464 EAPOL-Key frames; previously, that source address was used as the 1465 destination for EAPOL-Key frames and in key derivation; now, BSSID is 1466 used even if the source address does not match with it 1467 (this resolves an interoperability issue with Thomson SpeedTouch 580) 1468 * added a workaround for UDP-based control interface (which was used in 1469 Windows builds before this release) to prevent packets with forged 1470 addresses from being accepted as local control requests 1471 * removed ndis_events.cpp and possibility of using external 1472 ndis_events.exe; C version (ndis_events.c) is fully functional and 1473 there is no desire to maintain two separate versions of this 1474 implementation 1475 * ndis_events: Changed NDIS event notification design to use WMI to 1476 learn the adapter description through Win32_PnPEntity class; this 1477 should fix some cases where the adapter name was not recognized 1478 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500 1479 USB) [Bug 113] 1480 * fixed selection of the first network in ap_scan=2 mode; previously, 1481 wpa_supplicant could get stuck in SCANNING state when only the first 1482 network for enabled (e.g., after 'wpa_cli select_network 0') 1483 * winsvc: added support for configuring ctrl_interface parameters in 1484 registry (ctrl_interface string value in 1485 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is 1486 required to enable control interface (previously, this was hardcoded 1487 to be enabled) 1488 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4 1489 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format 1490 1491 2006-06-20 - v0.5.4 1492 * fixed build with CONFIG_STAKEY=y [Bug 143] 1493 * added support for doing MLME (IEEE 802.11 management frame 1494 processing) in wpa_supplicant when using Devicescape IEEE 802.11 1495 stack (wireless-dev.git tree) 1496 * added a new network block configuration option, fragment_size, to 1497 configure the maximum EAP fragment size 1498 * driver_ndis: Disable WZC automatically for the selected interface to 1499 avoid conflicts with two programs trying to control the radio; WZC 1500 will be re-enabled (if it was enabled originally) when wpa_supplicant 1501 is terminated 1502 * added an experimental TLSv1 client implementation 1503 (CONFIG_TLS=internal) that can be used instead of an external TLS 1504 library, e.g., to reduce total size requirement on systems that do 1505 not include any TLS library by default (this is not yet complete; 1506 basic functionality is there, but certificate validation is not yet 1507 included) 1508 * added PeerKey handshake implementation for IEEE 802.11e 1509 direct link setup (DLS) to replace STAKey handshake 1510 * fixed WPA PSK update through ctrl_iface for the case where the old 1511 PSK was derived from an ASCII passphrase and the new PSK is set as 1512 a raw PSK (hex string) 1513 * added new configuration option for identifying which network block 1514 was used (id_str in wpa_supplicant.conf; included on 1515 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental 1516 variable in wpa_cli action scripts; in addition WPA_ID variable is 1517 set to the current unique identifier that wpa_supplicant assigned 1518 automatically for the network and that can be used with 1519 GET_NETWORK/SET_NETWORK ctrl_iface commands) 1520 * wpa_cli action script is now called only when the connect/disconnect 1521 status changes or when associating with a different network 1522 * fixed configuration parser not to remove CCMP from group cipher list 1523 if WPA-None (adhoc) is used (pairwise=NONE in that case) 1524 * fixed integrated NDIS events processing not to hang the process due 1525 to a missed change in eloop_win.c API in v0.5.3 [Bug 155] 1526 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK, 1527 draft-clancy-emu-eap-shared-secret-00.txt) 1528 * added Microsoft Visual Studio 2005 solution and project files for 1529 build wpa_supplicant for Windows (see vs2005 subdirectory) 1530 * eloop_win: fixed unregistration of Windows events 1531 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet 1532 at the end of RSN pre-authentication and added unregistration of 1533 a Windows event to avoid getting eloop_win stuck with an invalid 1534 handle 1535 * driver_ndis: added support for selecting AP based on BSSID 1536 * added new environmental variable for wpa_cli action scripts: 1537 WPA_CTRL_DIR is the current control interface directory 1538 * driver_ndis: added support for using NDISUIO instead of WinPcap for 1539 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new 1540 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build 1541 wpa_supplicant without requiring WinPcap; note that using NDISUIO 1542 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows 1543 only one application to open the device 1544 * changed NDIS driver naming to only include device GUID, e.g., 1545 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap 1546 specific \Device\NPF_ prefix before the GUID; the prefix is still 1547 allowed for backwards compatibility, but it is not required anymore 1548 when specifying the interface 1549 * driver_ndis: re-initialize driver interface is the adapter is removed 1550 and re-inserted [Bug 159] 1551 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on 1552 big endian hosts [Bug 146] 1553 1554 2006-04-27 - v0.5.3 1555 * fixed EAP-GTC response to include correct user identity when run as 1556 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2) 1557 * driver_ndis: Fixed encryption mode configuration for unencrypted 1558 networks (some NDIS drivers ignored this, but others, e.g., Broadcom, 1559 refused to associate with open networks) [Bug 106] 1560 * driver_ndis: use BSSID OID polling to detect when IBSS network is 1561 formed even when ndis_events code is included since some NDIS drivers 1562 do not generate media connect events in IBSS mode 1563 * config_winreg: allow global ctrl_interface parameter to be configured 1564 in Windows registry 1565 * config_winreg: added support for saving configuration data into 1566 Windows registry 1567 * added support for controlling network device operational state 1568 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see 1569 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client 1570 that can use this information) 1571 * driver_wext: added support for WE-21 change to SSID configuration 1572 * driver_wext: fixed privacy configuration for static WEP keys mode 1573 [Bug 140] 1574 * added an optional driver_ops callback for MLME-SETPROTECTION.request 1575 primitive 1576 * added support for EAP-SAKE (no EAP method number allocated yet, so 1577 this is using the same experimental type 255 as EAP-PSK) 1578 * added support for dynamically loading EAP methods (.so files) instead 1579 of requiring them to be statically linked in; this is disabled by 1580 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information 1581 on how to use this) 1582 1583 2006-03-19 - v0.5.2 1584 * do not try to use USIM APDUs when initializing PC/SC for SIM card 1585 access for a network that has not enabled EAP-AKA 1586 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in 1587 v0.5.1 due to the new support for expanded EAP types) 1588 * added support for generating EAP Expanded Nak 1589 * try to fetch scan results once before requesting new scan when 1590 starting up in ap_scan=1 mode (this can speed up initial association 1591 a lot with, e.g., madwifi-ng driver) 1592 * added support for receiving EAPOL frames from a Linux bridge 1593 interface (-bbr0 on command line) 1594 * fixed EAPOL re-authentication for sessions that used PMKSA caching 1595 * changed EAP method registration to use a dynamic list of methods 1596 instead of a static list generated at build time 1597 * fixed PMKSA cache deinitialization not to use freed memory when 1598 removing PMKSA entries 1599 * fixed a memory leak in EAP-TTLS re-authentication 1600 * reject WPA/WPA2 message 3/4 if it does not include any valid 1601 WPA/RSN IE 1602 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg 1603 if the driver does not support SIOCSIWAUTH 1604 1605 2006-01-29 - v0.5.1 1606 * driver_test: added better support for multiple APs and STAs by using 1607 a directory with sockets that include MAC address for each device in 1608 the name (driver_param=test_dir=/tmp/test) 1609 * added support for EAP expanded type (vendor specific EAP methods) 1610 * added AP_SCAN command into ctrl_iface so that ap_scan configuration 1611 option can be changed if needed 1612 * wpa_cli/wpa_gui: skip non-socket files in control directory when 1613 using UNIX domain sockets; this avoids selecting an incorrect 1614 interface (e.g., a PID file could be in this directory, even though 1615 use of this directory for something else than socket files is not 1616 recommended) 1617 * fixed TLS library deinitialization after RSN pre-authentication not 1618 to disable TLS library for normal authentication 1619 * driver_wext: Remove null-termination from SSID length if the driver 1620 used it; some Linux drivers do this and they were causing problems in 1621 wpa_supplicant not finding matching configuration block. This change 1622 would break a case where the SSID actually ends in '\0', but that is 1623 not likely to happen in real use. 1624 * fixed PMKSA cache processing not to trigger deauthentication if the 1625 current PMKSA cache entry is replaced with a valid new entry 1626 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes 1627 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or 1628 ap_scan=2) 1629 1630 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases) 1631 * added experimental STAKey handshake implementation for IEEE 802.11e 1632 direct link setup (DLS); note: this is disabled by default in both 1633 build and runtime configuration (can be enabled with CONFIG_STAKEY=y 1634 and stakey=1) 1635 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to 1636 decrypt AT_ENCR_DATA attributes correctly 1637 * fixed EAP-AKA to allow resynchronization within the same session 1638 * made code closer to ANSI C89 standard to make it easier to port to 1639 other C libraries and compilers 1640 * started moving operating system or C library specific functions into 1641 wrapper functions defined in os.h and implemented in os_*.c to make 1642 code more portable 1643 * wpa_supplicant can now be built with Microsoft Visual C++ 1644 (e.g., with the freely available Toolkit 2003 version or Visual 1645 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an 1646 example makefile for nmake 1647 * added support for using Windows registry for command line parameters 1648 (CONFIG_MAIN=main_winsvc) and configuration data 1649 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry 1650 contents; this version can be run both as a Windows service and as a 1651 normal application; 'wpasvc.exe app' to start as applicant, 1652 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service, 1653 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to 1654 unregister a service 1655 * made it possible to link ndis_events.exe functionality into 1656 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED 1657 * added better support for multiple control interface backends 1658 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported 1659 * fixed PC/SC code to use correct length for GSM AUTH command buffer 1660 and to not use pioRecvPci with SCardTransmit() calls; these were not 1661 causing visible problems with pcsc-lite, but Windows Winscard.dll 1662 refused the previously used parameters; this fixes EAP-SIM and 1663 EAP-AKA authentication using SIM/USIM card under Windows 1664 * added new event loop implementation for Windows using 1665 WaitForMultipleObject() instead of select() in order to allow waiting 1666 for non-socket objects; this can be selected with 1667 CONFIG_ELOOP=eloop_win in .config 1668 * added support for selecting l2_packet implementation in .config 1669 (CONFIG_L2_PACKET; following options are available now: linux, pcap, 1670 winpcap, freebsd, none) 1671 * added new l2_packet implementation for WinPcap 1672 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to 1673 reduce latency in EAPOL receive processing from about 100 ms to about 1674 3 ms 1675 * added support for EAP-FAST key derivation using other ciphers than 1676 RC4-128-SHA for authentication and AES128-SHA for provisioning 1677 * added support for configuring CA certificate as DER file and as a 1678 configuration blob 1679 * fixed private key configuration as configuration blob and added 1680 support for using PKCS#12 as a blob 1681 * tls_gnutls: added support for using PKCS#12 files; added support for 1682 session resumption 1683 * added support for loading trusted CA certificates from Windows 1684 certificate store: ca_cert="cert_store://<name>", where <name> is 1685 likely CA (Intermediate CA certificates) or ROOT (root certificates) 1686 * added C version of ndis_events.cpp and made it possible to build this 1687 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more 1688 easily on cross-compilation builds 1689 * added wpasvc.exe into Windows binary release; this is an alternative 1690 version of wpa_supplicant.exe with configuration backend using 1691 Windows registry and with the entry point designed to run as a 1692 Windows service 1693 * integrated ndis_events.exe functionality into wpa_supplicant.exe and 1694 wpasvc.exe and removed this additional tool from the Windows binary 1695 release since it is not needed anymore 1696 * load winscard.dll functions dynamically when building with MinGW 1697 since MinGW does not yet include winscard library 1698 1699 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases) 1700 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap 1701 and WinPcap to receive frames sent to PAE group address 1702 * disable EAP state machine when IEEE 802.1X authentication is not used 1703 in order to get rid of bogus "EAP failed" messages 1704 * fixed OpenSSL error reporting to go through all pending errors to 1705 avoid confusing reports of old errors being reported at later point 1706 during handshake 1707 * fixed configuration file updating to not write empty variables 1708 (e.g., proto or key_mgmt) that the file parser would not accept 1709 * fixed ADD_NETWORK ctrl_iface command to use the same default values 1710 for variables as empty network definitions read from config file 1711 would get 1712 * fixed EAP state machine to not discard EAP-Failure messages in many 1713 cases (e.g., during TLS handshake) 1714 * fixed a infinite loop in private key reading if the configured file 1715 cannot be parsed successfully 1716 * driver_madwifi: added support for madwifi-ng 1717 * wpa_gui: do not display password/PSK field contents 1718 * wpa_gui: added CA certificate configuration 1719 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID 1720 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if 1721 the new AP is using different WPA/RSN IE 1722 * use longer timeout for IEEE 802.11 association to avoid problems with 1723 drivers that may take more than five second to associate 1724 1725 2005-10-27 - v0.4.6 1726 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in 1727 RSN IE, but WPA IE would match with wpa_supplicant configuration 1728 * added support for named configuration blobs in order to avoid having 1729 to use file system for external files (e.g., certificates); 1730 variables can be set to "blob://<blob name>" instead of file path to 1731 use a named blob; supported fields: pac_file, client_cert, 1732 private_key 1733 * fixed RSN pre-authentication (it was broken in the clean up of WPA 1734 state machine interface in v0.4.5) 1735 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make 1736 sure the driver configures broadcast decryption correctly 1737 * added ca_path (and ca_path2) configuration variables that can be used 1738 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the 1739 system-wide trusted CA list 1740 * added support for starting wpa_supplicant without a configuration 1741 file (-C argument must be used to set ctrl_interface parameter for 1742 this case; in addition, -p argument can be used to provide 1743 driver_param; these new arguments can also be used with a 1744 configuration to override the values from the configuration) 1745 * added global control interface that can be optionally used for adding 1746 and removing network interfaces dynamically (-g command line argument 1747 for both wpa_supplicant and wpa_cli) without having to restart 1748 wpa_supplicant process 1749 * wpa_gui: 1750 - try to save configuration whenever something is modified 1751 - added WEP key configuration 1752 - added possibility to edit the current network configuration 1753 * driver_ndis: fixed driver polling not to increase frequency on each 1754 received EAPOL frame due to incorrectly cancelled timeout 1755 * added simple configuration file examples (in examples subdirectory) 1756 * fixed driver_wext.c to filter wireless events based on ifindex to 1757 avoid interfaces receiving events from other interfaces 1758 * delay sending initial EAPOL-Start couple of seconds to speed up 1759 authentication for the most common case of Authenticator starting 1760 EAP authentication immediately after association 1761 1762 2005-09-25 - v0.4.5 1763 * added a workaround for clearing keys with ndiswrapper to allow 1764 roaming from WPA enabled AP to plaintext one 1765 * added docbook documentation (doc/docbook) that can be used to 1766 generate, e.g., man pages 1767 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for 1768 PF_PACKET in order to prepare for network devices that do not use 1769 Ethernet headers (e.g., network stack with native IEEE 802.11 frames) 1770 * use receipt of EAPOL-Key frame as a lower layer success indication 1771 for EAP state machine to allow recovery from dropped EAP-Success 1772 frame 1773 * cleaned up internal EAPOL frame processing by not including link 1774 layer (Ethernet) header during WPA and EAPOL/EAP processing; this 1775 header is added only when transmitted the frame; this makes it easier 1776 to use wpa_supplicant on link layers that use different header than 1777 Ethernet 1778 * updated EAP-PSK to use draft 9 by default since this can now be 1779 tested with hostapd; removed support for draft 3, including 1780 server_nai configuration option from network blocks 1781 * driver_wired: add PAE address to the multicast address list in order 1782 to be able to receive EAPOL frames with drivers that do not include 1783 these multicast addresses by default 1784 * driver_wext: add support for WE-19 1785 * added support for multiple configuration backends (CONFIG_BACKEND 1786 option); currently, only 'file' is supported (i.e., the format used 1787 in wpa_supplicant.conf) 1788 * added support for updating configuration ('wpa_cli save_config'); 1789 this is disabled by default and can be enabled with global 1790 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli 1791 and wpa_gui to store the configuration changes in a permanent store 1792 * added GET_NETWORK ctrl_iface command 1793 (e.g., 'wpa_cli get_network 0 ssid') 1794 1795 2005-08-21 - v0.4.4 1796 * replaced OpenSSL patch for EAP-FAST support 1797 (openssl-tls-extensions.patch) with a more generic and correct 1798 patch (the new patch is not compatible with the previous one, so the 1799 OpenSSL library will need to be patched with the new patch in order 1800 to be able to build wpa_supplicant with EAP-FAST support) 1801 * added support for using Windows certificate store (through CryptoAPI) 1802 for client certificate and private key operations (EAP-TLS) 1803 (see wpa_supplicant.conf for more information on how to configure 1804 this with private_key) 1805 * ported wpa_gui to Windows 1806 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be 1807 built with the open source version of the Qt4 for Windows 1808 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used 1809 with drivers that do not support WPA 1810 * ndis_events: fixed Windows 2000 support 1811 * added support for enabling/disabling networks from the list of all 1812 configured networks ('wpa_cli enable_network <network id>' and 1813 'wpa_cli disable_network <network id>') 1814 * added support for adding and removing network from the current 1815 configuration ('wpa_cli add_network' and 'wpa_cli remove_network 1816 <network id>'); added networks are disabled by default and they can 1817 be enabled with enable_network command once the configuration is done 1818 for the new network; note: configuration file is not yet updated, so 1819 these new networks are lost when wpa_supplicant is restarted 1820 * added support for setting network configuration parameters through 1821 the control interface, for example: 1822 wpa_cli set_network 0 ssid "\"my network\"" 1823 * fixed parsing of strings that include both " and # within double 1824 quoted area (e.g., "start"#end") 1825 * added EAP workaround for PEAP session resumption: allow outer, 1826 i.e., not tunneled, EAP-Success to terminate session since; this can 1827 be disabled with eap_workaround=0 1828 (this was allowed for PEAPv1 before, but now it is also allowed for 1829 PEAPv0 since at least one RADIUS authentication server seems to be 1830 doing this for PEAPv0, too) 1831 * wpa_gui: added preliminary support for adding new networks to the 1832 wpa_supplicant configuration (double click on the scan results to 1833 open network configuration) 1834 1835 2005-06-26 - v0.4.3 1836 * removed interface for external EAPOL/EAP supplicant (e.g., 1837 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required 1838 anymore and is unlikely to be used by anyone 1839 * driver_ndis: fixed WinPcap 3.0 support 1840 * fixed build with CONFIG_DNET_PCAP=y on Linux 1841 * l2_packet: moved different implementations into separate files 1842 (l2_packet_*.c) 1843 1844 2005-06-12 - v0.4.2 1845 * driver_ipw: updated driver structures to match with ipw2200-1.0.4 1846 (note: ipw2100-1.1.0 is likely to require an update to work with 1847 this) 1848 * added support for using ap_scan=2 mode with multiple network blocks; 1849 wpa_supplicant will go through the networks one by one until the 1850 driver reports a successful association; this uses the same order for 1851 networks as scan_ssid=1 scans, i.e., the priority field is ignored 1852 and the network block order in the file is used instead 1853 * fixed a potential issue in RSN pre-authentication ending up using 1854 freed memory if pre-authentication times out 1855 * added support for matching alternative subject name extensions of the 1856 authentication server certificate; new configuration variables 1857 altsubject_match and altsubject_match2 1858 * driver_ndis: added support for IEEE 802.1X authentication with wired 1859 NDIS drivers 1860 * added support for querying private key password (EAP-TLS) through the 1861 control interface (wpa_cli/wpa_gui) if one is not included in the 1862 configuration file 1863 * driver_broadcom: fixed couple of memory leaks in scan result 1864 processing 1865 * EAP-PAX is now registered as EAP type 46 1866 * fixed EAP-PAX MAC calculation 1867 * fixed EAP-PAX CK and ICK key derivation 1868 * added support for using password with EAP-PAX (as an alternative to 1869 entering key with eappsk); SHA-1 hash of the password will be used as 1870 the key in this case 1871 * added support for arbitrary driver interface parameters through the 1872 configuration file with a new driver_param field; this adds a new 1873 driver_ops function set_param() 1874 * added possibility to override l2_packet module with driver interface 1875 API (new send_eapol handler); this can be used to implement driver 1876 specific TX/RX functions for EAPOL frames 1877 * fixed ctrl_interface_group processing for the case where gid is 1878 entered as a number, not group name 1879 * driver_test: added support for testing hostapd with wpa_supplicant 1880 by using test driver interface without any kernel drivers or network 1881 cards 1882 1883 2005-05-22 - v0.4.1 1884 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL 1885 packets to be encrypted; this was apparently broken by the changed 1886 ioctl order in v0.4.0 1887 * driver_madwifi: added preliminary support for compiling against 'BSD' 1888 branch of madwifi CVS tree 1889 * added support for EAP-MSCHAPv2 password retries within the same EAP 1890 authentication session 1891 * added support for password changes with EAP-MSCHAPv2 (used when the 1892 password has expired) 1893 * added support for reading additional certificates from PKCS#12 files 1894 and adding them to the certificate chain 1895 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys 1896 were used 1897 * fixed a possible double free in EAP-TTLS fast-reauthentication when 1898 identity or password is entered through control interface 1899 * display EAP Notification messages to user through control interface 1900 with "CTRL-EVENT-EAP-NOTIFICATION" prefix 1901 * added GUI version of wpa_cli, wpa_gui; this is not build 1902 automatically with 'make'; use 'make wpa_gui' to build (this requires 1903 Qt development tools) 1904 * added 'disconnect' command to control interface for setting 1905 wpa_supplicant in state where it will not associate before 1906 'reassociate' command has been used 1907 * added support for selecting a network from the list of all configured 1908 networks ('wpa_cli select_network <network id>'; this disabled all 1909 other networks; to re-enable, 'wpa_cli select_network any') 1910 * added support for getting scan results through control interface 1911 * added EAP workaround for PEAPv1 session resumption: allow outer, 1912 i.e., not tunneled, EAP-Success to terminate session since; this can 1913 be disabled with eap_workaround=0 1914 1915 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases) 1916 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be 1917 used to reduce the size of the wpa_supplicant considerably if 1918 debugging code is not needed 1919 * fixed EAPOL-Key validation to drop packets with invalid Key Data 1920 Length; such frames could have crashed wpa_supplicant due to buffer 1921 overflow 1922 * added support for wired authentication (IEEE 802.1X on wired 1923 Ethernet); driver interface 'wired' 1924 * obsoleted set_wpa() handler in the driver interface API (it can be 1925 replaced by moving enable/disable functionality into init()/deinit()) 1926 (calls to set_wpa() are still present for backwards compatibility, 1927 but they may be removed in the future) 1928 * driver_madwifi: fixed association in plaintext mode 1929 * modified the EAP workaround that accepts EAP-Success with incorrect 1930 Identifier to be even less strict about verification in order to 1931 interoperate with some authentication servers 1932 * added support for sending TLS alerts 1933 * added support for 'any' SSID wildcard; if ssid is not configured or 1934 is set to an empty string, any SSID will be accepted for non-WPA AP 1935 * added support for asking PIN (for SIM) from frontends (e.g., 1936 wpa_cli); if a PIN is needed, but not included in the configuration 1937 file, a control interface request is sent and EAP processing is 1938 delayed until the PIN is available 1939 * added support for using external devices (e.g., a smartcard) for 1940 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config); 1941 new wpa_supplicant.conf variables: 1942 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path 1943 - network: engine, engine_id, key_id 1944 * added experimental support for EAP-PAX 1945 * added monitor mode for wpa_cli (-a<path to a program to run>) that 1946 allows external commands (e.g., shell scripts) to be run based on 1947 wpa_supplicant events, e.g., when authentication has been completed 1948 and data connection is ready; other related wpa_cli arguments: 1949 -B (run in background), -P (write PID file); wpa_supplicant has a new 1950 command line argument (-W) that can be used to make it wait until a 1951 control interface command is received in order to avoid missing 1952 events 1953 * added support for opportunistic WPA2 PMKSA key caching (disabled by 1954 default, can be enabled with proactive_key_caching=1) 1955 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where 1956 Authenticator rejects PMKSA caching attempt and the driver is not 1957 using assoc_info events 1958 * added -P<pid file> argument for wpa_supplicant to write the current 1959 process id into a file 1960 1961 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases) 1962 * added new phase1 option parameter, include_tls_length=1, to force 1963 wpa_supplicant to add TLS Message Length field to all TLS messages 1964 even if the packet is not fragmented; this may be needed with some 1965 authentication servers 1966 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when 1967 using drivers that take care of AP selection (e.g., when using 1968 ap_scan=2) 1969 * fixed reprocessing of pending request after ctrl_iface requests for 1970 identity/password/otp 1971 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of 1972 EAP-PEAP and EAP-TTLS 1973 * all drivers using driver_wext: set interface up and select Managed 1974 mode when starting wpa_supplicant; set interface down when exiting 1975 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both 1976 ipw2100 and ipw2200; please note that this also changed the 1977 configuration variable in .config to CONFIG_DRIVER_IPW 1978 1979 2005-01-24 - v0.3.6 1980 * fixed a busy loop introduced in v0.3.5 for scan result processing 1981 when no matching AP is found 1982 1983 2005-01-23 - v0.3.5 1984 * added a workaround for an interoperability issue with a Cisco AP 1985 when using WPA2-PSK 1986 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as 1987 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow 1988 retransmission of dropped frames) 1989 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version 1990 (e.g., segfault when processing EAPOL-Key frames) 1991 * fixed EAP workaround and fast reauthentication configuration for 1992 RSN pre-authentication; previously these were disabled and 1993 pre-authentication would fail if the used authentication server 1994 requires EAP workarounds 1995 * added support for blacklisting APs that fail or timeout 1996 authentication in ap_scan=1 mode so that all APs are tried in cases 1997 where the ones with strongest signal level are failing authentication 1998 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS 1999 authentication attempt 2000 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded 2001 in the previous authentication (previously, only Phase 1 success was 2002 verified) 2003 2004 2005-01-09 - v0.3.4 2005 * added preliminary support for IBSS (ad-hoc) mode configuration 2006 (mode=1 in network block); this included a new key_mgmt mode 2007 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no 2008 key management; see wpa_supplicant.conf for more details and an 2009 example on how to configure this (note: this is currently implemented 2010 only for driver_hostapd.c, but the changes should be trivial to add 2011 in associate() handler for other drivers, too (assuming the driver 2012 supports WPA-None) 2013 * added preliminary port for native Windows (i.e., no cygwin) using 2014 mingw 2015 2016 2005-01-02 - v0.3.3 2017 * added optional support for GNU Readline and History Libraries for 2018 wpa_cli (CONFIG_READLINE) 2019 * cleaned up EAP state machine <-> method interface and number of 2020 small problems with error case processing not terminating on 2021 EAP-Failure but waiting for timeout 2022 * added couple of workarounds for interoperability issues with a 2023 Cisco AP when using WPA2 2024 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt); 2025 Note: This requires a patch for openssl to add support for TLS 2026 extensions and number of workarounds for operations without 2027 certificates. Proof of concept type of experimental patch is 2028 included in openssl-tls-extensions.patch. 2029 2030 2004-12-19 - v0.3.2 2031 * fixed private key loading for cases where passphrase is not set 2032 * fixed Windows/cygwin L2 packet handler freeing; previous version 2033 could cause a segfault when RSN pre-authentication was completed 2034 * added support for PMKSA caching with drivers that generate RSN IEs 2035 (e.g., NDIS); currently, this is only implemented in driver_ndis.c, 2036 but similar code can be easily added to driver_ndiswrapper.c once 2037 ndiswrapper gets full support for RSN PMKSA caching 2038 * improved recovery from PMKID mismatches by requesting full EAP 2039 authentication in case of failed PMKSA caching attempt 2040 * driver_ndis: added support for NDIS NdisMIncidateStatus() events 2041 (this requires that ndis_events is ran while wpa_supplicant is 2042 running) 2043 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys 2044 * added support for driver interfaces to replace the interface name 2045 based on driver/OS specific mapping, e.g., in case of driver_ndis, 2046 this allows the beginning of the adapter description to be used as 2047 the interface name 2048 * added support for CR+LF (Windows-style) line ends in configuration 2049 file 2050 * driver_ndis: enable radio before starting scanning, disable radio 2051 when exiting 2052 * modified association event handler to set portEnabled = FALSE before 2053 clearing port Valid in order to reset EAP state machine and avoid 2054 problems with new authentication getting ignored because of state 2055 machines ending up in AUTHENTICATED/SUCCESS state based on old 2056 information 2057 * added support for driver events to add PMKID candidates in order to 2058 allow drivers to give priority to most likely roaming candidates 2059 * driver_hostap: moved PrivacyInvoked configuration to associate() 2060 function so that this will not be set for plaintext connections 2061 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver 2062 interface can distinguish plaintext and IEEE 802.1X (no WPA) 2063 authentication 2064 * fixed static WEP key configuration to use broadcast/default type for 2065 all keys (previously, the default TX key was configured as pairwise/ 2066 unicast key) 2067 * driver_ndis: added legacy WPA capability detection for non-WPA2 2068 drivers 2069 * added support for setting static WEP keys for IEEE 802.1X without 2070 dynamic WEP keying (eapol_flags=0) 2071 2072 2004-12-12 - v0.3.1 2073 * added support for reading PKCS#12 (PFX) files (as a replacement for 2074 PEM/DER) to get certificate and private key (CONFIG_PKCS12) 2075 * fixed compilation with CONFIG_PCSC=y 2076 * added new ap_scan mode, ap_scan=2, for drivers that take care of 2077 association, but need to be configured with security policy and SSID, 2078 e.g., ndiswrapper and NDIS driver; this mode should allow such 2079 drivers to work with hidden SSIDs and optimized roaming; when 2080 ap_scan=2 is used, only the first network block in the configuration 2081 file is used and this configuration should have explicit security 2082 policy (i.e., only one option in the lists) for key_mgmt, pairwise, 2083 group, proto variables 2084 * added experimental port of wpa_supplicant for Windows 2085 - driver_ndis.c driver interface (NDIS OIDs) 2086 - currently, this requires cygwin and WinPcap 2087 - small utility, win_if_list, can be used to get interface name 2088 * control interface can now be removed at build time; add 2089 CONFIG_CTRL_IFACE=y to .config to maintain old functionality 2090 * optional Xsupplicant interface can now be removed at build time; 2091 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back) 2092 * added auth_alg to driver interface associate() parameters to make it 2093 easier for drivers to configure authentication algorithm as part of 2094 the association 2095 2096 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases) 2097 * driver_broadcom: added new driver interface for Broadcom wl.o driver 2098 (a generic driver for Broadcom IEEE 802.11a/g cards) 2099 * wpa_cli: fixed parsing of -p <path> command line argument 2100 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS 2101 ACK, not tunneled EAP-Success (of which only the first byte was 2102 actually send due to a bug in previous code); this seems to 2103 interoperate with most RADIUS servers that implements PEAPv1 2104 * PEAPv1: added support for terminating PEAP authentication on tunneled 2105 EAP-Success message; this can be configured by adding 2106 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf 2107 (some RADIUS servers require this whereas others require a tunneled 2108 reply 2109 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to 2110 the old label for key derivation; previously, the default was 1, 2111 but it looks like most existing PEAPv1 implementations use the old 2112 label which is thus more suitable default option 2113 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt) 2114 * fixed parsing of wep_tx_keyidx 2115 * added support for configuring list of allowed Phase 2 EAP types 2116 (for both EAP-PEAP and EAP-TTLS) instead of only one type 2117 * added support for configuring IEEE 802.11 authentication algorithm 2118 (auth_alg; mainly for using Shared Key authentication with static 2119 WEP keys) 2120 * added support for EAP-AKA (with UMTS SIM) 2121 * fixed couple of errors in PCSC handling that could have caused 2122 random-looking errors for EAP-SIM 2123 * added support for EAP-SIM pseudonyms and fast re-authentication 2124 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS 2125 session resumption) 2126 * added support for EAP-SIM with two challanges 2127 (phase1="sim_min_num_chal=3" can be used to require three challenges) 2128 * added support for configuring DH/DSA parameters for an ephemeral DH 2129 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters 2130 dh_file and dh_file2 (phase 2); this adds support for using DSA keys 2131 and optional DH key exchange to achieve forward secracy with RSA keys 2132 * added support for matching subject of the authentication server 2133 certificate with a substring when using EAP-TLS/PEAP/TTLS; new 2134 configuration variables subject_match and subject_match2 2135 * changed SSID configuration in driver_wext.c (used by many driver 2136 interfaces) to use ssid_len+1 as the length for SSID since some Linux 2137 drivers expect this 2138 * fixed couple of unaligned reads in scan result parsing to fix WPA 2139 connection on some platforms (e.g., ARM) 2140 * added driver interface for Intel ipw2100 driver 2141 * added support for LEAP with WPA 2142 * added support for larger scan results report (old limit was 4 kB of 2143 data, i.e., about 35 or so APs) when using Linux wireless extensions 2144 v17 or newer 2145 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start 2146 only if there is a PMKSA cache entry for the current AP 2147 * fixed error handling for case where reading of scan results fails: 2148 must schedule a new scan or wpa_supplicant will remain waiting 2149 forever 2150 * changed debug output to remove shared password/key material by 2151 default; all key information can be included with -K command line 2152 argument to match the previous behavior 2153 * added support for timestamping debug log messages (disabled by 2154 default, can be enabled with -t command line argument) 2155 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104 2156 if keys are not configured to be used; this fixes IEEE 802.1X mode 2157 with drivers that use this information to configure whether Privacy 2158 bit can be in Beacon frames (e.g., ndiswrapper) 2159 * avoid clearing driver keys if no keys have been configured since last 2160 key clear request; this seems to improve reliability of group key 2161 handshake for ndiswrapper & NDIS driver which seems to be suffering 2162 of some kind of timing issue when the keys are cleared again after 2163 association 2164 * changed driver interface API: 2165 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which 2166 version is being used (now, this is set to 2; previously, it was 2167 not defined) 2168 - pass pointer to private data structure to all calls 2169 - the new API is not backwards compatible; all in-tree driver 2170 interfaces has been converted to the new API 2171 * added support for controlling multiple interfaces (radios) per 2172 wpa_supplicant process; each interface needs to be listed on the 2173 command line (-c, -i, -D arguments) with -N as a separator 2174 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi) 2175 * added a workaround for EAP servers that incorrectly use same Id for 2176 sequential EAP packets 2177 * changed libpcap/libdnet configuration to use .config variable, 2178 CONFIG_DNET_PCAP, instead of requiring Makefile modification 2179 * improved downgrade attack detection in IE verification of msg 3/4: 2180 verify both WPA and RSN IEs, if present, not only the selected one; 2181 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or 2182 Probe Response frame, and RSN is enabled in wpa_supplicant 2183 configuration 2184 * fixed WPA msg 3/4 processing to allow Key Data field contain other 2185 IEs than just one WPA IE 2186 * added support for FreeBSD and driver interface for the BSD net80211 2187 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the 2188 required kernel mods have not yet been committed 2189 * made EAP workarounds configurable; enabled by default, can be 2190 disabled with network block option eap_workaround=0 2191 2192 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases) 2193 * resolved couple of interoperability issues with EAP-PEAPv1 and 2194 Phase 2 (inner EAP) fragment reassembly 2195 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the 2196 AP is using non-zero key index for the unicast key and key index zero 2197 for the broadcast key 2198 * driver_hostap: fixed IEEE 802.1X WEP key updates and 2199 re-authentication by allowing unencrypted EAPOL frames when not using 2200 WPA 2201 * added a new driver interface, 'wext', which uses only standard, 2202 driver independent functionality in Linux wireless extensions; 2203 currently, this can be used only for non-WPA IEEE 802.1X mode, but 2204 eventually, this is to be extended to support full WPA/WPA2 once 2205 Linux wireless extensions get support for this 2206 * added support for mode in which the driver is responsible for AP 2207 scanning and selection; this is disabled by default and can be 2208 enabled with global ap_scan=0 variable in wpa_supplicant.conf; 2209 this mode can be used, e.g., with generic 'wext' driver interface to 2210 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver 2211 supporting wireless extensions. 2212 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g., 2213 operation with an AP that does not include SSID in the Beacon frames) 2214 * added support for new EAP authentication methods: 2215 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP 2216 * added support for asking one-time-passwords from frontends (e.g., 2217 wpa_cli); this 'otp' command works otherwise like 'password' command, 2218 but the password is used only once and the frontend will be asked for 2219 a new password whenever a request from authenticator requires a 2220 password; this can be used with both EAP-OTP and EAP-GTC 2221 * changed wpa_cli to automatically re-establish connection so that it 2222 does not need to be re-started when wpa_supplicant is terminated and 2223 started again 2224 * improved user data (identity/password/otp) requests through 2225 frontends: process pending EAPOL packets after getting new 2226 information so that full authentication does not need to be 2227 restarted; in addition, send pending requests again whenever a new 2228 frontend is attached 2229 * changed control frontends to use a new directory for socket files to 2230 make it easier for wpa_cli to automatically select between interfaces 2231 and to provide access control for the control interface; 2232 wpa_supplicant.conf: ctrl_interface is now a path 2233 (/var/run/wpa_supplicant is the recommended path) and 2234 ctrl_interface_group can be used to select which group gets access to 2235 the control interface; 2236 wpa_cli: by default, try to connect to the first interface available 2237 in /var/run/wpa_supplicant; this path can be overriden with -p option 2238 and an interface can be selected with -i option (i.e., in most common 2239 cases, wpa_cli does not need to get any arguments) 2240 * added support for LEAP 2241 * added driver interface for Linux ndiswrapper 2242 * added priority option for network blocks in the configuration file; 2243 this allows networks to be grouped based on priority (the scan 2244 results are searched for matches with network blocks in this order) 2245 2246 2004-06-20 - v0.2.3 2247 * sort scan results to improve AP selection 2248 * fixed control interface socket removal for some error cases 2249 * improved scan requesting and authentication timeout 2250 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and 2251 TLS processing 2252 * PEAP version can now be forced with phase1="peapver=<ver>" 2253 (mostly for testing; by default, the highest version supported by 2254 both the Supplicant and Authentication Server is selected 2255 automatically) 2256 * added support for madwifi driver (Atheros ar521x) 2257 * added a workaround for cases where AP sets Install Tx/Rx bit for 2258 WPA Group Key messages when pairwise keys are used (without this, 2259 the Group Key would be used for Tx and the AP would drop frames 2260 from the station) 2261 * added GSM SIM/USIM interface for GSM authentication algorithm for 2262 EAP-SIM; this requires pcsc-lite 2263 * added support for ATMEL AT76C5XXx driver 2264 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator 2265 does not include key data in the EAPOL-Key frame (i.e., part of 2266 EAP keying material is used as data encryption key) 2267 * added support for using plaintext and static WEP networks 2268 (key_mgmt=NONE) 2269 2270 2004-05-31 - v0.2.2 2271 * added support for new EAP authentication methods: 2272 EAP-TTLS/EAP-MD5-Challenge 2273 EAP-TTLS/EAP-GTC 2274 EAP-TTLS/EAP-MSCHAPv2 2275 EAP-TTLS/EAP-TLS 2276 EAP-TTLS/MSCHAPv2 2277 EAP-TTLS/MSCHAP 2278 EAP-TTLS/PAP 2279 EAP-TTLS/CHAP 2280 EAP-PEAP/TLS 2281 EAP-PEAP/GTC 2282 EAP-PEAP/MD5-Challenge 2283 EAP-GTC 2284 EAP-SIM (not yet complete; needs GSM/SIM authentication interface) 2285 * added support for anonymous identity (to be used when identity is 2286 sent in plaintext; real identity will be used within TLS protected 2287 tunnel (e.g., with EAP-TTLS) 2288 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli 2289 * added support for requesting identity and password information using 2290 control interface; in other words, the password for EAP-PEAP or 2291 EAP-TTLS does not need to be included in the configuration file since 2292 a frontand (e.g., wpa_cli) can ask it from the user 2293 * improved RSN pre-authentication to use a candidate list and process 2294 all candidates from each scan; not only one per scan 2295 * fixed RSN IE and WPA IE capabilities field parsing 2296 * ignore Tx bit in GTK IE when Pairwise keys are used 2297 * avoid making new scan requests during IEEE 802.1X negotiation 2298 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant 2299 with TLS support (this replaces the included implementation with 2300 library code to save about 8 kB since the library code is needed 2301 anyway for TLS) 2302 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support 2303 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config) 2304 2305 2004-05-06 - v0.2.1 2306 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1) 2307 Supplicant 2308 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1] 2309 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf] 2310 - EAP-MD5 (cannot be used with WPA-RADIUS) 2311 [draft-ietf-eap-rfc2284bis-09.txt] 2312 - EAP-TLS [RFC 2716] 2313 - EAP-MSCHAPv2 (currently used only with EAP-PEAP) 2314 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt] 2315 [draft-kamath-pppext-eap-mschapv2-00.txt] 2316 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by 2317 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey) 2318 - new configuration file options: eap, identity, password, ca_cert, 2319 client_cert, privatekey, private_key_passwd 2320 - Xsupplicant is not required anymore, but it can be used by 2321 disabling the internal IEEE 802.1X Supplicant with -e command line 2322 option 2323 - this code is not included in the default build; Makefile need to 2324 be edited for this (uncomment lines for selected functionality) 2325 - EAP-TLS and EAP-PEAP require openssl libraries 2326 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..) 2327 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys 2328 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X 2329 EAPOL-Key frames instead of WPA key handshakes) 2330 * added support for IEEE 802.11i/RSN (WPA2) 2331 - improved PTK Key Handshake 2332 - PMKSA caching, pre-authentication 2333 * fixed wpa_supplicant to ignore possible extra data after WPA 2334 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using 2335 TPTK' error from message 3 of 4-Way Handshake in case the AP 2336 includes extra data after the EAPOL-Key) 2337 * added interface for external programs (frontends) to control 2338 wpa_supplicant 2339 - CLI example (wpa_cli) with interactive mode and command line 2340 mode 2341 - replaced SIGUSR1 status/statistics with the new control interface 2342 * made some feature compile time configurable 2343 - .config file for make 2344 - driver interfaces (hostap, hermes, ..) 2345 - EAPOL/EAP functions 2346 2347 2004-02-15 - v0.2.0 2348 * Initial version of wpa_supplicant 2349
