Disabled by default, enable by 1102 config option disassoc_low_ack. 1103 * nl80211: 1104 - Support GTK rekey offload. 1105 - Support PMKSA candidate events. This adds support for RSN 1106 pre-authentication with nl80211 interface and drivers that handle 1107 roaming internally. 1108 * dbus: 1109 - Add a DBus signal for EAP SM requests, emitted on the Interface 1110 object. 1111 - Export max scan ssids supported by the driver as MaxScanSSID. 1112 - Add signal Certification for information about server certification. 1113 - Add BSSExpireAge and BSSExpireCount interface properties and 1114 support set/get, which allows for setting BSS cache expiration age 1115 and expiration scan count. 1116 - Add ConfigFile to AddInterface properties. 1117 - Add Interface.Country property and support to get/set the value. 1118 - Add DBus property CurrentAuthMode. 1119 - P2P DBus API added. 1120 - Emit property changed events (for property BSSs) when adding/ 1121 removing BSSs. 1122 - Treat '' in SSIDs of Interface.Scan as a request for broadcast 1123 scan, instead of ignoring it. 1124 - Add DBus getter/setter for FastReauth. 1125 - Raise PropertiesChanged on org.freedesktop.DBus.Properties. 1126 * wpa_cli: 1127 - Send AP-STA-DISCONNECTED event when an AP disconnects a station 1128 due to inactivity. 1129 - Make second argument to set command optional. This can be used to 1130 indicate a zero length value. 1131 - Add signal_poll command. 1132 - Add bss_expire_age and bss_expire_count commands to set/get BSS 1133 cache expiration age and expiration scan count. 1134 - Add ability to set scan interval (the time in seconds wpa_s waits 1135 before requesting a new scan after failing to find a suitable 1136 network in scan results) using scan_interval command. 1137 - Add event CTRL-EVENT-ASSOC-REJECT for association rejected. 1138 - Add command get version, that returns wpa_supplicant version string. 1139 - Add command sta_autoconnect for disabling automatic reconnection 1140 on receiving disconnection event. 1141 - Setting bssid parameter to an empty string "" or any can now be 1142 used to clear the bssid_set flag in a network block, i.e., to remove 1143 bssid filtering. 1144 - Add tdls_testing command to add a special testing feature for 1145 changing TDLS behavior. Build param CONFIG_TDLS_TESTING must be 1146 enabled as well. 1147 - For interworking, add wpa_cli commands interworking_select, 1148 interworking_connect, anqp_get, fetch_anqp, and stop_fetch_anqp. 1149 - Many P2P commands were added.

CONFIG_WPA_CLI_EDIT=y 1157 can now be used to build wpa_cli with internal implementation of 1158 line editing and history support. This can be used as a replacement 1159 for CONFIG_READLINE=y. 1160 * AP mode: Add max_num_sta config option, which can be used to limit 1161 the number of stations allowed to connect to the AP. 1162 * Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad 1163 config file. 1164 * wext: Increase scan timeout from 5 to 10 seconds. 1165 * Add blacklist command, allowing an external program to 1166 manage the BSS blacklist and display its current contents. 1167 * WPS: 1168 - Add wpa_cli wps_pin get command for generating random PINs. This can 1169 be used in a UI to generate a PIN without starting WPS (or P2P) 1170 operation. 1171 - Set RF bands based on driver capabilities, instead of hardcoding 1172 them. 1173 - Add mechanism for indicating non-standard WPS errors. 1174 - Add CONFIG_WPS_REG_DISABLE_OPEN=y option to disable open networks 1175 by default. 1176 - Add wps_ap_pin cli command for wpa_supplicant AP mode. 1177 - Add wps_check_pin cli command for processing PIN from user input. 1178 UIs can use this command to process a PIN entered by a user and to 1179 validate the checksum digit (if present). 1180 - Cancel WPS operation on PBC session overlap detection. 1181 - New wps_cancel command in wpa_cli will cancel a pending WPS 1182 operation. 1183 - wpa_cli action: Add WPS_EVENT_SUCCESS and WPS_EVENT_FAIL handlers. 1184 - Trigger WPS config update on Manufacturer, Model Name, Model 1185 Number, and Serial Number changes. 1186 - Fragment size is now configurable for EAP-WSC peer. Use 1187 wpa_cli set wps_fragment_size <val>. 1188 - Disable AP PIN after 10 consecutive failures. Slow down attacks on 1189 failures up to 10. 1190 - Allow AP to start in Enrollee mode without AP PIN for probing, to 1191 be compatible with Windows 7. 1192 - Add Config Error into WPS-FAIL events to provide more info to the 1193 user on how to resolve the issue. 1194 - Label and Display config methods are not allowed to be enabled 1195 at the same time, since it is unclear which PIN to use if both 1196 methods are advertised. 1197 - When controlling multiple interfaces: 1198 - apply WPS commands to all interfaces configured to use WPS 1199 - apply WPS config changes to all interfaces that use WPS 1200 - when an attack is detected on any interface, disable AP PIN on 1201 all interfaces 1202 * WPS ER: 1203 - Add special AP Setup Locked mode to allow read only ER. 1204 ap_setup_locked=2 can now be used to enable a special mode where 1205 WPS ER can learn the current AP settings, but cannot change them. 1206 - Show SetSelectedRegistrar events as ctrl_iface events 1207 - Add wps_er_set_config to enroll a network based on a local 1208 network configuration block instead of having to (re-)learn the 1209 current AP settings with wps_er_learn. 1210 - Allow AP filtering based on IP address, add ctrl_iface event for 1211 learned AP settings, add wps_er_config command to configure an AP. 1212 * WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2) 1213 - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool 1214 for testing protocol extensibility. 1215 - Add build option CONFIG_WPS_STRICT to allow disabling of WPS 1216 workarounds. 1217 - Add support for AuthorizedMACs attribute. 1218 * TDLS: 1219 - Propagate TDLS related nl80211 capability flags from kernel and 1220 add them as driver capability flags. If the driver doesn't support 1221 capabilities, assume TDLS is supported internally. When TDLS is 1222 explicitly not supported, disable all user facing TDLS operations. 1223 - Allow TDLS to be disabled at runtime (mostly for testing). 1224 Use set tdls_disabled. 1225 - Honor AP TDLS settings that prohibit/allow TDLS. 1226 - Add a special testing feature for changing TDLS behavior. Use 1227 CONFIG_TDLS_TESTING build param to enable. Configure at runtime 1228 with tdls_testing cli command. 1229 - Add support for TDLS 802.11z. 1230 * wlantest: Add a tool wlantest for IEEE802.11 protocol testing. 1231 wlantest can be used to capture frames from a monitor interface 1232 for realtime capturing or from pcap files for offline analysis. 1233 * Interworking: Support added for 802.11u. Enable in .config with 1234 CONFIG_INTERWORKING. See wpa_supplicant.conf for config parameters 1235 for interworking. wpa_cli commands added to support this are 1236 interworking_select, interworking_connect, anqp_get, fetch_anqp, 1237 and stop_fetch_anqp. 1238 * Android: Add build and runtime support for Android wpa_supplicant. 1239 * bgscan learn: Add new bgscan that learns BSS information based on 1240 previous scans, and uses that information to dynamically generate 1241 the list of channels for background scans. 1242 * Add a new debug message level for excessive information. Use 1243 -ddd to enable. 1244 * TLS: Add support for tls_disable_time_checks=1 in client mode. 1245 * Internal TLS: 1246 - Add support for TLS v1.1 (RFC 4346). Enable with build parameter 1247 CONFIG_TLSV11. 1248 - Add domainComponent parser for X.509 names. 1249 * Linux: Add RFKill support by adding an interface state "disabled". 1250 * Reorder some IEs to get closer to IEEE 802.11 standard. Move 1251 WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames. 1252 Move HT IEs to be later in (Re)Assoc Resp. 1253 * Solaris: Add support for wired 802.1X client. 1254 * Wi-Fi Direct support. See README-P2P for more information. 1255 * Many bugfixes. 1256 12572010-04-18 - v0.7.2 1258 * nl80211: fixed number of issues with roaming 1259 * avoid unnecessary roaming if multiple APs with similar signal 1260 strength are present in scan results 1261 * add TLS client events and server probing to ease design of 1262 automatic detection of EAP parameters 1263 * add option for server certificate matching (SHA256 hash of the 1264 certificate) instead of trusted CA certificate configuration 1265 * bsd: Cleaned up driver wrapper and added various low-level 1266 configuration options 1267 * wpa_gui-qt4: do not show too frequent WPS AP available events as 1268 tray messages 1269 * TNC: fixed issues with fragmentation 1270 * EAP-TNC: add Flags field into fragment acknowledgement (needed to 1271 interoperate with other implementations; may potentially breaks 1272 compatibility with older wpa_supplicant/hostapd versions) 1273 * wpa_cli: added option for using a separate process to receive event 1274 messages to reduce latency in showing these 1275 (CFLAGS += -DCONFIG_WPA_CLI_FORK=y in .config to enable this) 1276 * maximum BSS table size can now be configured (bss_max_count) 1277 * BSSes to be included in the BSS table can be filtered based on 1278 configured SSIDs to save memory (filter_ssids) 1279 * fix number of issues with IEEE 802.11r/FT; this version is not 1280 backwards compatible with old versions 1281 * nl80211: add support for IEEE 802.11r/FT protocol (both over-the-air 1282 and over-the-DS) 1283 * add freq_list network configuration parameter to allow the AP 1284 selection to filter out entries based on the operating channel 1285 * add signal strength change events for bgscan; this allows more 1286 dynamic changes to background scanning interval based on changes in 1287 the signal strength with the current AP; this improves roaming within 1288 ESS quite a bit, e.g., with bgscan="simple:30:-45:300" in the network 1289 configuration block to request background scans less frequently when 1290 signal strength remains good and to automatically trigger background 1291 scans whenever signal strength drops noticeably 1292 (this is currently only available with nl80211) 1293 * add BSSID and reason code (if available) to disconnect event messages 1294 * wpa_gui-qt4: more complete support for translating the GUI with 1295 linguist and add German translation 1296 * fix DH padding with internal crypto code (mainly, for WPS) 1297 * do not trigger initial scan automatically anymore if there are no 1298 enabled networks 1299 13002010-01-16 - v0.7.1 1301 * cleaned up driver wrapper API (struct wpa_driver_ops); the new API 1302 is not fully backwards compatible, so out-of-tree driver wrappers 1303 will need modifications 1304 * cleaned up various module interfaces 1305 * merge hostapd and wpa_supplicant developers' documentation into a 1306 single document 1307 * nl80211: use explicit deauthentication to clear cfg80211 state to 1308 avoid issues when roaming between APs 1309 * dbus: major design changes in the new D-Bus API 1310 (fi.w1.wpa_supplicant1) 1311 * nl80211: added support for IBSS networks 1312 * added internal debugging mechanism with backtrace support and memory 1313 allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y) 1314 * added WPS ER unsubscription command to more cleanly unregister from 1315 receiving UPnP events when ER is terminated 1316 * cleaned up AP mode operations to avoid need for virtual driver_ops 1317 wrapper 1318 * added BSS table to maintain more complete scan result information 1319 over multiple scans (that may include only partial results) 1320 * wpa_gui-qt4: update Peers dialog information more dynamically while 1321 the dialog is kept open 1322 * fixed PKCS#12 use with OpenSSL 1.0.0 1323 * driver_wext: Added cfg80211-specific optimization to avoid some 1324 unnecessary scans and to speed up association 1325 13262009-11-21 - v0.7.0 1327 * increased wpa_cli ping interval to 5 seconds and made this 1328 configurable with a new command line options (-G<seconds>) 1329 * fixed scan buffer processing with WEXT to handle up to 65535 1330 byte result buffer (previously, limited to 32768 bytes) 1331 * allow multiple driver wrappers to be specified on command line 1332 (e.g., -Dnl80211,wext); the first one that is able to initialize the 1333 interface will be used 1334 * added support for multiple SSIDs per scan request to optimize 1335 scan_ssid=1 operations in ap_scan=1 mode (i.e., search for hidden 1336 SSIDs); this requires driver support and can currently be used only 1337 with nl80211 1338 * added support for WPS USBA out-of-band mechanism with USB Flash 1339 Drives (UFD) (CONFIG_WPS_UFD=y) 1340 * driver_ndis: add PAE group address to the multicast address list to 1341 fix wired IEEE 802.1X authentication 1342 * fixed IEEE 802.11r key derivation function to match with the standard 1343 (note: this breaks interoperability with previous version) [Bug 303] 1344 * added better support for drivers that allow separate authentication 1345 and association commands (e.g., mac80211-based Linux drivers with 1346 nl80211; SME in wpa_supplicant); this allows over-the-air FT protocol 1347 to be used (IEEE 802.11r) 1348 * fixed SHA-256 based key derivation function to match with the 1349 standard when using CCMP (for IEEE 802.11r and IEEE 802.11w) 1350 (note: this breaks interoperability with previous version) [Bug 307] 1351 * use shared driver wrapper files with hostapd 1352 * added AP mode functionality (CONFIG_AP=y) with mode=2 in the network 1353 block; this can be used for open and WPA2-Personal networks 1354 (optionally, with WPS); this links in parts of hostapd functionality 1355 into wpa_supplicant 1356 * wpa_gui-qt4: added new Peers dialog to show information about peers 1357 (other devices, including APs and stations, etc. in the neighborhood) 1358 * added support for WPS External Registrar functionality (configure APs 1359 and enroll new devices); can be used with wpa_gui-qt4 Peers dialog 1360 and wpa_cli commands wps_er_start, wps_er_stop, wps_er_pin, 1361 wps_er_pbc, wps_er_learn 1362 (this can also be used with a new 'none' driver wrapper if no 1363 wireless device or IEEE 802.1X on wired is needed) 1364 * driver_nl80211: multiple updates to provide support for new Linux 1365 nl80211/mac80211 functionality 1366 * updated management frame protection to use IEEE Std 802.11w-2009 1367 * fixed number of small WPS issues and added workarounds to 1368 interoperate with common deployed broken implementations 1369 * added support for NFC out-of-band mechanism with WPS 1370 * driver_ndis: fixed wired IEEE 802.1X authentication with PAE group 1371 address frames 1372 * added preliminary support for IEEE 802.11r RIC processing 1373 * added support for specifying subset of enabled frequencies to scan 1374 (scan_freq option in the network configuration block); this can speed 1375 up scanning process considerably if it is known that only a small 1376 subset of channels is actually used in the network (this is currently 1377 supported only with -Dnl80211) 1378 * added a workaround for race condition between receiving the 1379 association event and the following EAPOL-Key 1380 * added background scan and roaming infrastructure to allow 1381 network-specific optimizations to be used to improve roaming within 1382 an ESS (same SSID) 1383 * added new DBus interface (fi.w1.wpa_supplicant1) 1384 13852009-01-06 - v0.6.7 1386 * added support for Wi-Fi Protected Setup (WPS) 1387 (wpa_supplicant can now be configured to act as a WPS Enrollee to 1388 enroll credentials for a network using PIN and PBC methods; in 1389 addition, wpa_supplicant can act as a wireless WPS Registrar to 1390 configure an AP); WPS support can be enabled by adding CONFIG_WPS=y 1391 into .config and setting the runtime configuration variables in 1392 wpa_supplicant.conf (see WPS section in the example configuration 1393 file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to 1394 manage WPS negotiation; see README-WPS for more details 1395 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf) 1396 * added support for using driver_test over UDP socket 1397 * fixed PEAPv0 Cryptobinding interoperability issue with Windows Server 1398 2008 NPS; optional cryptobinding is now enabled (again) by default 1399 * fixed PSK editing in wpa_gui 1400 * changed EAP-GPSK to use the IANA assigned EAP method type 51 1401 * added a Windows installer that includes WinPcap and all the needed 1402 DLLs; in addition, it set up the registry automatically so that user 1403 will only need start wpa_gui to get prompted to start the wpasvc 1404 servide and add a new interface if needed through wpa_gui dialog 1405 * updated management frame protection to use IEEE 802.11w/D7.0 1406 14072008-11-23 - v0.6.6 1408 * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA 1409 (can be used to simulate test SIM/USIM card with a known private key; 1410 enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config 1411 and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration) 1412 * added a new network configuration option, wpa_ptk_rekey, that can be 1413 used to enforce frequent PTK rekeying, e.g., to mitigate some attacks 1414 against TKIP deficiencies 1415 * added an optional mitigation mechanism for certain attacks against 1416 TKIP by delaying Michael MIC error reports by a random amount of time 1417 between 0 and 60 seconds; this can be enabled with a build option 1418 CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config 1419 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits, 1420 not bytes 1421 * updated OpenSSL code for EAP-FAST to use an updated version of the 1422 session ticket overriding API that was included into the upstream 1423 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is 1424 needed with that version anymore) 1425 * updated userspace MLME instructions to match with the current Linux 1426 mac80211 implementation; please also note that this can only be used 1427 with driver_nl80211.c (the old code from driver_wext.c was removed) 1428 * added support (Linux only) for RoboSwitch chipsets (often found in 1429 consumer grade routers); driver interface 'roboswitch' 1430 * fixed canceling of PMKSA caching when using drivers that generate 1431 RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know 1432 about 1433 14342008-11-01 - v0.6.5 1435 * added support for SHA-256 as X.509 certificate digest when using the 1436 internal X.509/TLSv1 implementation 1437 * updated management frame protection to use IEEE 802.11w/D6.0 1438 * added support for using SHA256-based stronger key derivation for WPA2 1439 (IEEE 802.11w) 1440 * fixed FT (IEEE 802.11r) authentication after a failed association to 1441 use correct FTIE 1442 * added support for configuring Phase 2 (inner/tunneled) authentication 1443 method with wpa_gui-qt4 1444 14452008-08-10 - v0.6.4 1446 * added support for EAP Sequences in EAP-FAST Phase 2 1447 * added support for using TNC with EAP-FAST 1448 * added driver_ps3 for the PS3 Linux wireless driver 1449 * added support for optional cryptobinding with PEAPv0 1450 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to 1451 allow fallback to full handshake if server rejects PAC-Opaque 1452 * added fragmentation support for EAP-TNC 1453 * added support for parsing PKCS #8 formatted private keys into the 1454 internal TLS implementation (both PKCS #1 RSA key and PKCS #8 1455 encapsulated RSA key can now be used) 1456 * added option of using faster, but larger, routines in the internal 1457 LibTomMath (for internal TLS implementation) to speed up DH and RSA 1458 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y) 1459 * fixed race condition between disassociation event and group key 1460 handshake to avoid getting stuck in incorrect state [Bug 261] 1461 * fixed opportunistic key caching (proactive_key_caching) 1462 14632008-02-22 - v0.6.3 1464 * removed 'nai' and 'eappsk' network configuration variables that were 1465 previously used for configuring user identity and key for EAP-PSK, 1466 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the 1467 replacement for 'nai' (if old configuration used a separate 1468 'identity' value, that would now be configured as 1469 'anonymous_identity'). 'password' field is now used as the 1470 replacement for 'eappsk' (it can also be set using hexstring to 1471 present random binary data) 1472 * removed '-w' command line parameter (wait for interface to be added, 1473 if needed); cleaner way of handling this functionality is to use an 1474 external mechanism (e.g., hotplug scripts) that start wpa_supplicant 1475 when an interface is added 1476 * updated FT support to use the latest draft, IEEE 802.11r/D9.0 1477 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for 1478 indicating when new scan results become available 1479 * added new ctrl_iface command, BSS, to allow scan results to be 1480 fetched without hitting the message size limits (this command 1481 can be used to iterate through the scan results one BSS at the time) 1482 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION 1483 attributes in EAP-SIM Start/Response when using fast reauthentication 1484 * fixed EAPOL not to end up in infinite loop when processing dynamic 1485 WEP keys with IEEE 802.1X 1486 * fixed problems in getting NDIS events from WMI on Windows 2000 1487 14882008-01-01 - v0.6.2 1489 * added support for Makefile builds to include debug-log-to-a-file 1490 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line) 1491 * fixed EAP-SIM and EAP-AKA message parser to validate attribute 1492 lengths properly to avoid potential crash caused by invalid messages 1493 * added data structure for storing allocated buffers (struct wpabuf); 1494 this does not affect wpa_supplicant usage, but many of the APIs 1495 changed and various interfaces (e.g., EAP) is not compatible with old 1496 versions 1497 * added support for protecting EAP-AKA/Identity messages with 1498 AT_CHECKCODE (optional feature in RFC 4187) 1499 * added support for protected result indication with AT_RESULT_IND for 1500 EAP-SIM and EAP-AKA (phase1="result_ind=1") 1501 * added driver_wext workaround for race condition between scanning and 1502 association with drivers that take very long time to scan all 1503 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now 1504 using a longer hardcoded timeout for the scan if the driver supports 1505 notifications for scan completion (SIOCGIWSCAN event); this helps, 1506 e.g., in cases where wpa_supplicant and madwifi driver ended up in 1507 loop where the driver did not even try to associate 1508 * stop EAPOL timer tick when no timers are in use in order to reduce 1509 power consumption (no need to wake up the process once per second) 1510 [Bug 237] 1511 * added support for privilege separation (run only minimal part of 1512 wpa_supplicant functionality as root and rest as unprivileged, 1513 non-root process); see 'Privilege separation' in README for details; 1514 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y 1515 in .config 1516 * changed scan results data structure to include all information 1517 elements to make it easier to support new IEs; old get_scan_result() 1518 driver_ops is still supported for backwards compatibility (results 1519 are converted internally to the new format), but all drivers should 1520 start using the new get_scan_results2() to make them more likely to 1521 work with new features 1522 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4 1523 application, i.e., it does not require Qt3Support anymore; Windows 1524 binary of wpa_gui.exe is now from this directory and only requires 1525 QtCore4.dll and QtGui4.dll libraries 1526 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs 1527 available as a separate package to make wpa_gui installation easier: 1528 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip 1529 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt); 1530 only shared key/password authentication is supported in this version 1531 15322007-11-24 - v0.6.1 1533 * added support for configuring password as NtPasswordHash 1534 (16-byte MD4 hash of password) in hash:<32 hex digits> format 1535 * added support for fallback from abbreviated TLS handshake to 1536 full handshake when using EAP-FAST (e.g., due to an expired 1537 PAC-Opaque) 1538 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 1539 draft (draft-ietf-emu-eap-gpsk-07.txt) 1540 * added support for drivers that take care of RSN 4-way handshake 1541 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and 1542 WPA_ALG_PMK in set_key) 1543 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in 1544 .config); this version supports only ap_scan=2 mode and allow the 1545 driver to take care of the 4-way handshake 1546 * fixed a buffer overflow in parsing TSF from scan results when using 1547 driver_wext.c with a driver that includes the TSF (e.g., iwl4965) 1548 [Bug 232] 1549 * updated FT support to use the latest draft, IEEE 802.11r/D8.0 1550 * fixed an integer overflow issue in the ASN.1 parser used by the 1551 (experimental) internal TLS implementation to avoid a potential 1552 buffer read overflow 1553 * fixed a race condition with -W option (wait for a control interface 1554 monitor before starting) that could have caused the first messages to 1555 be lost 1556 * added support for processing TNCC-TNCS-Messages to report 1557 recommendation (allow/none/isolate) when using TNC [Bug 243] 1558 15592007-05-28 - v0.6.0 1560 * added network configuration parameter 'frequency' for setting 1561 initial channel for IBSS (adhoc) networks 1562 * added experimental IEEE 802.11r/D6.0 support 1563 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48 1564 * updated EAP-PSK to use the IANA-allocated EAP type 47 1565 * fixed EAP-PAX key derivation 1566 * fixed EAP-PSK bit ordering of the Flags field 1567 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in 1568 tunnelled identity request (previously, the identifier from the outer 1569 method was used, not the tunnelled identifier which could be 1570 different) 1571 * added support for fragmentation of outer TLS packets during Phase 2 1572 of EAP-PEAP/TTLS/FAST 1573 * fixed EAP-TTLS AVP parser processing for too short AVP lengths 1574 * added support for EAP-FAST authentication with inner methods that 1575 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported 1576 for PAC provisioning) 1577 * added support for authenticated EAP-FAST provisioning 1578 * added support for configuring maximum number of EAP-FAST PACs to 1579 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string) 1580 * added support for storing EAP-FAST PACs in binary format 1581 (fast_pac_format=binary in phase1 string) 1582 * fixed dbus ctrl_iface to validate message interface before 1583 dispatching to avoid a possible segfault [Bug 190] 1584 * fixed PeerKey key derivation to use the correct PRF label 1585 * updated Windows binary build to link against OpenSSL 0.9.8d and 1586 added support for EAP-FAST 1587 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 1588 draft (draft-ietf-emu-eap-gpsk-04.txt) 1589 * fixed EAP-AKA Notification processing to allow Notification to be 1590 processed after AKA Challenge response has been sent 1591 * updated to use IEEE 802.11w/D2.0 for management frame protection 1592 (still experimental) 1593 * fixed EAP-TTLS implementation not to crash on use of freed memory 1594 if TLS library initialization fails 1595 * added support for EAP-TNC (Trusted Network Connect) 1596 (this version implements the EAP-TNC method and EAP-TTLS changes 1597 needed to run two methods in sequence (IF-T) and the IF-IMC and 1598 IF-TNCCS interfaces from TNCC) 1599 16002006-11-24 - v0.5.6 1601 * added experimental, integrated TLSv1 client implementation with the 1602 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by 1603 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in 1604 .config); this can be useful, e.g., if the target system does not 1605 have a suitable TLS library and a minimal code size is required 1606 (total size of this internal TLS/crypto code is bit under 50 kB on 1607 x86 and the crypto code is shared by rest of the supplicant so some 1608 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB) 1609 * removed STAKey handshake since PeerKey handshake has replaced it in 1610 IEEE 802.11ma and there are no known deployments of STAKey 1611 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 1612 draft (draft-ietf-emu-eap-gpsk-01.txt) 1613 * added preliminary implementation of IEEE 802.11w/D1.0 (management 1614 frame protection) 1615 (Note: this requires driver support to work properly.) 1616 (Note2: IEEE 802.11w is an unapproved draft and subject to change.) 1617 * fixed Windows named pipes ctrl_iface to not stop listening for 1618 commands if client program opens a named pipe and closes it 1619 immediately without sending a command 1620 * fixed USIM PIN status determination for the case that PIN is not 1621 needed (this allows EAP-AKA to be used with USIM cards that do not 1622 use PIN) 1623 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to 1624 be used with cards that do not support file selection based on 1625 partial AID 1626 * added support for matching the subjectAltName of the authentication 1627 server certificate against multiple name components (e.g., 1628 altsubject_match="DNS:server.example.com;DNS:server2.example.com") 1629 * fixed EAP-SIM/AKA key derivation for re-authentication case (only 1630 affects IEEE 802.1X with dynamic WEP keys) 1631 * changed ctrl_iface network configuration 'get' operations to not 1632 return password/key material; if these fields are requested, "*" 1633 will be returned if the password/key is set, but the value of the 1634 parameter is not exposed 1635 16362006-08-27 - v0.5.5 1637 * added support for building Windows version with UNICODE defined 1638 (wide-char functions) 1639 * driver_ndis: fixed static WEP configuration to avoid race condition 1640 issues with some NDIS drivers between association and setting WEP 1641 keys 1642 * driver_ndis: added validation for IELength value in scan results to 1643 avoid crashes when using buggy NDIS drivers [Bug 165] 1644 * fixed Release|Win32 target in the Visual Studio project files 1645 (previously, only Debug|Win32 target was set properly) 1646 * changed control interface API call wpa_ctrl_pending() to allow it to 1647 return -1 on error (e.g., connection lost); control interface clients 1648 will need to make sure that they verify that the value is indeed >0 1649 when determining whether there are pending messages 1650 * added an alternative control interface backend for Windows targets: 1651 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default 1652 control interface mechanism for Windows builds (previously, UDP to 1653 localhost was used) 1654 * changed ctrl_interface configuration for UNIX domain sockets: 1655 - deprecated ctrl_interface_group variable (it may be removed in 1656 future versions) 1657 - allow both directory and group be configured with ctrl_interface 1658 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel 1659 - ctrl_interface=/var/run/wpa_supplicant is still supported for the 1660 case when group is not changed 1661 * added support for controlling more than one interface per process in 1662 Windows version 1663 * added a workaround for a case where the AP is using unknown address 1664 (e.g., MAC address of the wired interface) as the source address for 1665 EAPOL-Key frames; previously, that source address was used as the 1666 destination for EAPOL-Key frames and in key derivation; now, BSSID is 1667 used even if the source address does not match with it 1668 (this resolves an interoperability issue with Thomson SpeedTouch 580) 1669 * added a workaround for UDP-based control interface (which was used in 1670 Windows builds before this release) to prevent packets with forged 1671 addresses from being accepted as local control requests 1672 * removed ndis_events.cpp and possibility of using external 1673 ndis_events.exe; C version (ndis_events.c) is fully functional and 1674 there is no desire to maintain two separate versions of this 1675 implementation 1676 * ndis_events: Changed NDIS event notification design to use WMI to 1677 learn the adapter description through Win32_PnPEntity class; this 1678 should fix some cases where the adapter name was not recognized 1679 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500 1680 USB) [Bug 113] 1681 * fixed selection of the first network in ap_scan=2 mode; previously, 1682 wpa_supplicant could get stuck in SCANNING state when only the first 1683 network for enabled (e.g., after 'wpa_cli select_network 0') 1684 * winsvc: added support for configuring ctrl_interface parameters in 1685 registry (ctrl_interface string value in 1686 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is 1687 required to enable control interface (previously, this was hardcoded 1688 to be enabled) 1689 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4 1690 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format 1691 16922006-06-20 - v0.5.4 1693 * fixed build with CONFIG_STAKEY=y [Bug 143] 1694 * added support for doing MLME (IEEE 802.11 management frame 1695 processing) in wpa_supplicant when using Devicescape IEEE 802.11 1696 stack (wireless-dev.git tree) 1697 * added a new network block configuration option, fragment_size, to 1698 configure the maximum EAP fragment size 1699 * driver_ndis: Disable WZC automatically for the selected interface to 1700 avoid conflicts with two programs trying to control the radio; WZC 1701 will be re-enabled (if it was enabled originally) when wpa_supplicant 1702 is terminated 1703 * added an experimental TLSv1 client implementation 1704 (CONFIG_TLS=internal) that can be used instead of an external TLS 1705 library, e.g., to reduce total size requirement on systems that do 1706 not include any TLS library by default (this is not yet complete; 1707 basic functionality is there, but certificate validation is not yet 1708 included) 1709 * added PeerKey handshake implementation for IEEE 802.11e 1710 direct link setup (DLS) to replace STAKey handshake 1711 * fixed WPA PSK update through ctrl_iface for the case where the old 1712 PSK was derived from an ASCII passphrase and the new PSK is set as 1713 a raw PSK (hex string) 1714 * added new configuration option for identifying which network block 1715 was used (id_str in wpa_supplicant.conf; included on 1716 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental 1717 variable in wpa_cli action scripts; in addition WPA_ID variable is 1718 set to the current unique identifier that wpa_supplicant assigned 1719 automatically for the network and that can be used with 1720 GET_NETWORK/SET_NETWORK ctrl_iface commands) 1721 * wpa_cli action script is now called only when the connect/disconnect 1722 status changes or when associating with a different network 1723 * fixed configuration parser not to remove CCMP from group cipher list 1724 if WPA-None (adhoc) is used (pairwise=NONE in that case) 1725 * fixed integrated NDIS events processing not to hang the process due 1726 to a missed change in eloop_win.c API in v0.5.3 [Bug 155] 1727 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK, 1728 draft-clancy-emu-eap-shared-secret-00.txt) 1729 * added Microsoft Visual Studio 2005 solution and project files for 1730 build wpa_supplicant for Windows (see vs2005 subdirectory) 1731 * eloop_win: fixed unregistration of Windows events 1732 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet 1733 at the end of RSN pre-authentication and added unregistration of 1734 a Windows event to avoid getting eloop_win stuck with an invalid 1735 handle 1736 * driver_ndis: added support for selecting AP based on BSSID 1737 * added new environmental variable for wpa_cli action scripts: 1738 WPA_CTRL_DIR is the current control interface directory 1739 * driver_ndis: added support for using NDISUIO instead of WinPcap for 1740 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new 1741 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build 1742 wpa_supplicant without requiring WinPcap; note that using NDISUIO 1743 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows 1744 only one application to open the device 1745 * changed NDIS driver naming to only include device GUID, e.g., 1746 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap 1747 specific \Device\NPF_ prefix before the GUID; the prefix is still 1748 allowed for backwards compatibility, but it is not required anymore 1749 when specifying the interface 1750 * driver_ndis: re-initialize driver interface is the adapter is removed 1751 and re-inserted [Bug 159] 1752 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on 1753 big endian hosts [Bug 146] 1754 17552006-04-27 - v0.5.3 1756 * fixed EAP-GTC response to include correct user identity when run as 1757 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2) 1758 * driver_ndis: Fixed encryption mode configuration for unencrypted 1759 networks (some NDIS drivers ignored this, but others, e.g., Broadcom, 1760 refused to associate with open networks) [Bug 106] 1761 * driver_ndis: use BSSID OID polling to detect when IBSS network is 1762 formed even when ndis_events code is included since some NDIS drivers 1763 do not generate media connect events in IBSS mode 1764 * config_winreg: allow global ctrl_interface parameter to be configured 1765 in Windows registry 1766 * config_winreg: added support for saving configuration data into 1767 Windows registry 1768 * added support for controlling network device operational state 1769 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see 1770 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client 1771 that can use this information) 1772 * driver_wext: added support for WE-21 change to SSID configuration 1773 * driver_wext: fixed privacy configuration for static WEP keys mode 1774 [Bug 140] 1775 * added an optional driver_ops callback for MLME-SETPROTECTION.request 1776 primitive 1777 * added support for EAP-SAKE (no EAP method number allocated yet, so 1778 this is using the same experimental type 255 as EAP-PSK) 1779 * added support for dynamically loading EAP methods (.so files) instead 1780 of requiring them to be statically linked in; this is disabled by 1781 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information 1782 on how to use this) 1783 17842006-03-19 - v0.5.2 1785 * do not try to use USIM APDUs when initializing PC/SC for SIM card 1786 access for a network that has not enabled EAP-AKA 1787 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in 1788 v0.5.1 due to the new support for expanded EAP types) 1789 * added support for generating EAP Expanded Nak 1790 * try to fetch scan results once before requesting new scan when 1791 starting up in ap_scan=1 mode (this can speed up initial association 1792 a lot with, e.g., madwifi-ng driver) 1793 * added support for receiving EAPOL frames from a Linux bridge 1794 interface (-bbr0 on command line) 1795 * fixed EAPOL re-authentication for sessions that used PMKSA caching 1796 * changed EAP method registration to use a dynamic list of methods 1797 instead of a static list generated at build time 1798 * fixed PMKSA cache deinitialization not to use freed memory when 1799 removing PMKSA entries 1800 * fixed a memory leak in EAP-TTLS re-authentication 1801 * reject WPA/WPA2 message 3/4 if it does not include any valid 1802 WPA/RSN IE 1803 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg 1804 if the driver does not support SIOCSIWAUTH 1805 18062006-01-29 - v0.5.1 1807 * driver_test: added better support for multiple APs and STAs by using 1808 a directory with sockets that include MAC address for each device in 1809 the name (driver_param=test_dir=/tmp/test) 1810 * added support for EAP expanded type (vendor specific EAP methods) 1811 * added AP_SCAN command into ctrl_iface so that ap_scan configuration 1812 option can be changed if needed 1813 * wpa_cli/wpa_gui: skip non-socket files in control directory when 1814 using UNIX domain sockets; this avoids selecting an incorrect 1815 interface (e.g., a PID file could be in this directory, even though 1816 use of this directory for something else than socket files is not 1817 recommended) 1818 * fixed TLS library deinitialization after RSN pre-authentication not 1819 to disable TLS library for normal authentication 1820 * driver_wext: Remove null-termination from SSID length if the driver 1821 used it; some Linux drivers do this and they were causing problems in 1822 wpa_supplicant not finding matching configuration block. This change 1823 would break a case where the SSID actually ends in '\0', but that is 1824 not likely to happen in real use. 1825 * fixed PMKSA cache processing not to trigger deauthentication if the 1826 current PMKSA cache entry is replaced with a valid new entry 1827 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes 1828 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or 1829 ap_scan=2) 1830 18312005-12-18 - v0.5.0 (beginning of 0.5.x development releases) 1832 * added experimental STAKey handshake implementation for IEEE 802.11e 1833 direct link setup (DLS); note: this is disabled by default in both 1834 build and runtime configuration (can be enabled with CONFIG_STAKEY=y 1835 and stakey=1) 1836 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to 1837 decrypt AT_ENCR_DATA attributes correctly 1838 * fixed EAP-AKA to allow resynchronization within the same session 1839 * made code closer to ANSI C89 standard to make it easier to port to 1840 other C libraries and compilers 1841 * started moving operating system or C library specific functions into 1842 wrapper functions defined in os.h and implemented in os_*.c to make 1843 code more portable 1844 * wpa_supplicant can now be built with Microsoft Visual C++ 1845 (e.g., with the freely available Toolkit 2003 version or Visual 1846 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an 1847 example makefile for nmake 1848 * added support for using Windows registry for command line parameters 1849 (CONFIG_MAIN=main_winsvc) and configuration data 1850 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry 1851 contents; this version can be run both as a Windows service and as a 1852 normal application; 'wpasvc.exe app' to start as applicant, 1853 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service, 1854 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to 1855 unregister a service 1856 * made it possible to link ndis_events.exe functionality into 1857 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED 1858 * added better support for multiple control interface backends 1859 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported 1860 * fixed PC/SC code to use correct length for GSM AUTH command buffer 1861 and to not use pioRecvPci with SCardTransmit() calls; these were not 1862 causing visible problems with pcsc-lite, but Windows Winscard.dll 1863 refused the previously used parameters; this fixes EAP-SIM and 1864 EAP-AKA authentication using SIM/USIM card under Windows 1865 * added new event loop implementation for Windows using 1866 WaitForMultipleObject() instead of select() in order to allow waiting 1867 for non-socket objects; this can be selected with 1868 CONFIG_ELOOP=eloop_win in .config 1869 * added support for selecting l2_packet implementation in .config 1870 (CONFIG_L2_PACKET; following options are available now: linux, pcap, 1871 winpcap, freebsd, none) 1872 * added new l2_packet implementation for WinPcap 1873 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to 1874 reduce latency in EAPOL receive processing from about 100 ms to about 1875 3 ms 1876 * added support for EAP-FAST key derivation using other ciphers than 1877 RC4-128-SHA for authentication and AES128-SHA for provisioning 1878 * added support for configuring CA certificate as DER file and as a 1879 configuration blob 1880 * fixed private key configuration as configuration blob and added 1881 support for using PKCS#12 as a blob 1882 * tls_gnutls: added support for using PKCS#12 files; added support for 1883 session resumption 1884 * added support for loading trusted CA certificates from Windows 1885 certificate store: ca_cert="cert_store://<name>", where <name> is 1886 likely CA (Intermediate CA certificates) or ROOT (root certificates) 1887 * added C version of ndis_events.cpp and made it possible to build this 1888 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more 1889 easily on cross-compilation builds 1890 * added wpasvc.exe into Windows binary release; this is an alternative 1891 version of wpa_supplicant.exe with configuration backend using 1892 Windows registry and with the entry point designed to run as a 1893 Windows service 1894 * integrated ndis_events.exe functionality into wpa_supplicant.exe and 1895 wpasvc.exe and removed this additional tool from the Windows binary 1896 release since it is not needed anymore 1897 * load winscard.dll functions dynamically when building with MinGW 1898 since MinGW does not yet include winscard library 1899 19002005-11-20 - v0.4.7 (beginning of 0.4.x stable releases) 1901 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap 1902 and WinPcap to receive frames sent to PAE group address 1903 * disable EAP state machine when IEEE 802.1X authentication is not used 1904 in order to get rid of bogus "EAP failed" messages 1905 * fixed OpenSSL error reporting to go through all pending errors to 1906 avoid confusing reports of old errors being reported at later point 1907 during handshake 1908 * fixed configuration file updating to not write empty variables 1909 (e.g., proto or key_mgmt) that the file parser would not accept 1910 * fixed ADD_NETWORK ctrl_iface command to use the same default values 1911 for variables as empty network definitions read from config file 1912 would get 1913 * fixed EAP state machine to not discard EAP-Failure messages in many 1914 cases (e.g., during TLS handshake) 1915 * fixed a infinite loop in private key reading if the configured file 1916 cannot be parsed successfully 1917 * driver_madwifi: added support for madwifi-ng 1918 * wpa_gui: do not display password/PSK field contents 1919 * wpa_gui: added CA certificate configuration 1920 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID 1921 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if 1922 the new AP is using different WPA/RSN IE 1923 * use longer timeout for IEEE 802.11 association to avoid problems with 1924 drivers that may take more than five second to associate 1925 19262005-10-27 - v0.4.6 1927 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in 1928 RSN IE, but WPA IE would match with wpa_supplicant configuration 1929 * added support for named configuration blobs in order to avoid having 1930 to use file system for external files (e.g., certificates); 1931 variables can be set to "blob://<blob name>" instead of file path to 1932 use a named blob; supported fields: pac_file, client_cert, 1933 private_key 1934 * fixed RSN pre-authentication (it was broken in the clean up of WPA 1935 state machine interface in v0.4.5) 1936 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make 1937 sure the driver configures broadcast decryption correctly 1938 * added ca_path (and ca_path2) configuration variables that can be used 1939 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the 1940 system-wide trusted CA list 1941 * added support for starting wpa_supplicant without a configuration 1942 file (-C argument must be used to set ctrl_interface parameter for 1943 this case; in addition, -p argument can be used to provide 1944 driver_param; these new arguments can also be used with a 1945 configuration to override the values from the configuration) 1946 * added global control interface that can be optionally used for adding 1947 and removing network interfaces dynamically (-g command line argument 1948 for both wpa_supplicant and wpa_cli) without having to restart 1949 wpa_supplicant process 1950 * wpa_gui: 1951 - try to save configuration whenever something is modified 1952 - added WEP key configuration 1953 - added possibility to edit the current network configuration 1954 * driver_ndis: fixed driver polling not to increase frequency on each 1955 received EAPOL frame due to incorrectly cancelled timeout 1956 * added simple configuration file examples (in examples subdirectory) 1957 * fixed driver_wext.c to filter wireless events based on ifindex to 1958 avoid interfaces receiving events from other interfaces 1959 * delay sending initial EAPOL-Start couple of seconds to speed up 1960 authentication for the most common case of Authenticator starting 1961 EAP authentication immediately after association 1962 19632005-09-25 - v0.4.5 1964 * added a workaround for clearing keys with ndiswrapper to allow 1965 roaming from WPA enabled AP to plaintext one 1966 * added docbook documentation (doc/docbook) that can be used to 1967 generate, e.g., man pages 1968 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for 1969 PF_PACKET in order to prepare for network devices that do not use 1970 Ethernet headers (e.g., network stack that includes IEEE 802.11 1971 header in the frames) 1972 * use receipt of EAPOL-Key frame as a lower layer success indication 1973 for EAP state machine to allow recovery from dropped EAP-Success 1974 frame 1975 * cleaned up internal EAPOL frame processing by not including link 1976 layer (Ethernet) header during WPA and EAPOL/EAP processing; this 1977 header is added only when transmitted the frame; this makes it easier 1978 to use wpa_supplicant on link layers that use different header than 1979 Ethernet 1980 * updated EAP-PSK to use draft 9 by default since this can now be 1981 tested with hostapd; removed support for draft 3, including 1982 server_nai configuration option from network blocks 1983 * driver_wired: add PAE address to the multicast address list in order 1984 to be able to receive EAPOL frames with drivers that do not include 1985 these multicast addresses by default 1986 * driver_wext: add support for WE-19 1987 * added support for multiple configuration backends (CONFIG_BACKEND 1988 option); currently, only 'file' is supported (i.e., the format used 1989 in wpa_supplicant.conf) 1990 * added support for updating configuration ('wpa_cli save_config'); 1991 this is disabled by default and can be enabled with global 1992 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli 1993 and wpa_gui to store the configuration changes in a permanent store 1994 * added GET_NETWORK ctrl_iface command 1995 (e.g., 'wpa_cli get_network 0 ssid') 1996 19972005-08-21 - v0.4.4 1998 * replaced OpenSSL patch for EAP-FAST support 1999 (openssl-tls-extensions.patch) with a more generic and correct 2000 patch (the new patch is not compatible with the previous one, so the 2001 OpenSSL library will need to be patched with the new patch in order 2002 to be able to build wpa_supplicant with EAP-FAST support) 2003 * added support for using Windows certificate store (through CryptoAPI) 2004 for client certificate and private key operations (EAP-TLS) 2005 (see wpa_supplicant.conf for more information on how to configure 2006 this with private_key) 2007 * ported wpa_gui to Windows 2008 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be 2009 built with the open source version of the Qt4 for Windows 2010 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used 2011 with drivers that do not support WPA 2012 * ndis_events: fixed Windows 2000 support 2013 * added support for enabling/disabling networks from the list of all 2014 configured networks ('wpa_cli enable_network <network id>' and 2015 'wpa_cli disable_network <network id>') 2016 * added support for adding and removing network from the current 2017 configuration ('wpa_cli add_network' and 'wpa_cli remove_network 2018 <network id>'); added networks are disabled by default and they can 2019 be enabled with enable_network command once the configuration is done 2020 for the new network; note: configuration file is not yet updated, so 2021 these new networks are lost when wpa_supplicant is restarted 2022 * added support for setting network configuration parameters through 2023 the control interface, for example: 2024 wpa_cli set_network 0 ssid "\"my network\"" 2025 * fixed parsing of strings that include both " and # within double 2026 quoted area (e.g., "start"#end") 2027 * added EAP workaround for PEAP session resumption: allow outer, 2028 i.e., not tunneled, EAP-Success to terminate session since; this can 2029 be disabled with eap_workaround=0 2030 (this was allowed for PEAPv1 before, but now it is also allowed for 2031 PEAPv0 since at least one RADIUS authentication server seems to be 2032 doing this for PEAPv0, too) 2033 * wpa_gui: added preliminary support for adding new networks to the 2034 wpa_supplicant configuration (double click on the scan results to 2035 open network configuration) 2036 20372005-06-26 - v0.4.3 2038 * removed interface for external EAPOL/EAP supplicant (e.g., 2039 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required 2040 anymore and is unlikely to be used by anyone 2041 * driver_ndis: fixed WinPcap 3.0 support 2042 * fixed build with CONFIG_DNET_PCAP=y on Linux 2043 * l2_packet: moved different implementations into separate files 2044 (l2_packet_*.c) 2045 20462005-06-12 - v0.4.2 2047 * driver_ipw: updated driver structures to match with ipw2200-1.0.4 2048 (note: ipw2100-1.1.0 is likely to require an update to work with 2049 this) 2050 * added support for using ap_scan=2 mode with multiple network blocks; 2051 wpa_supplicant will go through the networks one by one until the 2052 driver reports a successful association; this uses the same order for 2053 networks as scan_ssid=1 scans, i.e., the priority field is ignored 2054 and the network block order in the file is used instead 2055 * fixed a potential issue in RSN pre-authentication ending up using 2056 freed memory if pre-authentication times out 2057 * added support for matching alternative subject name extensions of the 2058 authentication server certificate; new configuration variables 2059 altsubject_match and altsubject_match2 2060 * driver_ndis: added support for IEEE 802.1X authentication with wired 2061 NDIS drivers 2062 * added support for querying private key password (EAP-TLS) through the 2063 control interface (wpa_cli/wpa_gui) if one is not included in the 2064 configuration file 2065 * driver_broadcom: fixed couple of memory leaks in scan result 2066 processing 2067 * EAP-PAX is now registered as EAP type 46 2068 * fixed EAP-PAX MAC calculation 2069 * fixed EAP-PAX CK and ICK key derivation 2070 * added support for using password with EAP-PAX (as an alternative to 2071 entering key with eappsk); SHA-1 hash of the password will be used as 2072 the key in this case 2073 * added support for arbitrary driver interface parameters through the 2074 configuration file with a new driver_param field; this adds a new 2075 driver_ops function set_param() 2076 * added possibility to override l2_packet module with driver interface 2077 API (new send_eapol handler); this can be used to implement driver 2078 specific TX/RX functions for EAPOL frames 2079 * fixed ctrl_interface_group processing for the case where gid is 2080 entered as a number, not group name 2081 * driver_test: added support for testing hostapd with wpa_supplicant 2082 by using test driver interface without any kernel drivers or network 2083 cards 2084 20852005-05-22 - v0.4.1 2086 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL 2087 packets to be encrypted; this was apparently broken by the changed 2088 ioctl order in v0.4.0 2089 * driver_madwifi: added preliminary support for compiling against 'BSD' 2090 branch of madwifi CVS tree 2091 * added support for EAP-MSCHAPv2 password retries within the same EAP 2092 authentication session 2093 * added support for password changes with EAP-MSCHAPv2 (used when the 2094 password has expired) 2095 * added support for reading additional certificates from PKCS#12 files 2096 and adding them to the certificate chain 2097 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys 2098 were used 2099 * fixed a possible double free in EAP-TTLS fast-reauthentication when 2100 identity or password is entered through control interface 2101 * display EAP Notification messages to user through control interface 2102 with "CTRL-EVENT-EAP-NOTIFICATION" prefix 2103 * added GUI version of wpa_cli, wpa_gui; this is not build 2104 automatically with 'make'; use 'make wpa_gui' to build (this requires 2105 Qt development tools) 2106 * added 'disconnect' command to control interface for setting 2107 wpa_supplicant in state where it will not associate before 2108 'reassociate' command has been used 2109 * added support for selecting a network from the list of all configured 2110 networks ('wpa_cli select_network <network id>'; this disabled all 2111 other networks; to re-enable, 'wpa_cli select_network any') 2112 * added support for getting scan results through control interface 2113 * added EAP workaround for PEAPv1 session resumption: allow outer, 2114 i.e., not tunneled, EAP-Success to terminate session since; this can 2115 be disabled with eap_workaround=0 2116 21172005-04-25 - v0.4.0 (beginning of 0.4.x development releases) 2118 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be 2119 used to reduce the size of the wpa_supplicant considerably if 2120 debugging code is not needed 2121 * fixed EAPOL-Key validation to drop packets with invalid Key Data 2122 Length; such frames could have crashed wpa_supplicant due to buffer 2123 overflow 2124 * added support for wired authentication (IEEE 802.1X on wired 2125 Ethernet); driver interface 'wired' 2126 * obsoleted set_wpa() handler in the driver interface API (it can be 2127 replaced by moving enable/disable functionality into init()/deinit()) 2128 (calls to set_wpa() are still present for backwards compatibility, 2129 but they may be removed in the future) 2130 * driver_madwifi: fixed association in plaintext mode 2131 * modified the EAP workaround that accepts EAP-Success with incorrect 2132 Identifier to be even less strict about verification in order to 2133 interoperate with some authentication servers 2134 * added support for sending TLS alerts 2135 * added support for 'any' SSID wildcard; if ssid is not configured or 2136 is set to an empty string, any SSID will be accepted for non-WPA AP 2137 * added support for asking PIN (for SIM) from frontends (e.g., 2138 wpa_cli); if a PIN is needed, but not included in the configuration 2139 file, a control interface request is sent and EAP processing is 2140 delayed until the PIN is available 2141 * added support for using external devices (e.g., a smartcard) for 2142 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config); 2143 new wpa_supplicant.conf variables: 2144 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path 2145 - network: engine, engine_id, key_id 2146 * added experimental support for EAP-PAX 2147 * added monitor mode for wpa_cli (-a<path to a program to run>) that 2148 allows external commands (e.g., shell scripts) to be run based on 2149 wpa_supplicant events, e.g., when authentication has been completed 2150 and data connection is ready; other related wpa_cli arguments: 2151 -B (run in background), -P (write PID file); wpa_supplicant has a new 2152 command line argument (-W) that can be used to make it wait until a 2153 control interface command is received in order to avoid missing 2154 events 2155 * added support for opportunistic WPA2 PMKSA key caching (disabled by 2156 default, can be enabled with proactive_key_caching=1) 2157 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where 2158 Authenticator rejects PMKSA caching attempt and the driver is not 2159 using assoc_info events 2160 * added -P<pid file> argument for wpa_supplicant to write the current 2161 process id into a file 2162 21632005-02-12 - v0.3.7 (beginning of 0.3.x stable releases) 2164 * added new phase1 option parameter, include_tls_length=1, to force 2165 wpa_supplicant to add TLS Message Length field to all TLS messages 2166 even if the packet is not fragmented; this may be needed with some 2167 authentication servers 2168 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when 2169 using drivers that take care of AP selection (e.g., when using 2170 ap_scan=2) 2171 * fixed reprocessing of pending request after ctrl_iface requests for 2172 identity/password/otp 2173 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of 2174 EAP-PEAP and EAP-TTLS 2175 * all drivers using driver_wext: set interface up and select Managed 2176 mode when starting wpa_supplicant; set interface down when exiting 2177 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both 2178 ipw2100 and ipw2200; please note that this also changed the 2179 configuration variable in .config to CONFIG_DRIVER_IPW 2180 21812005-01-24 - v0.3.6 2182 * fixed a busy loop introduced in v0.3.5 for scan result processing 2183 when no matching AP is found 2184 21852005-01-23 - v0.3.5 2186 * added a workaround for an interoperability issue with a Cisco AP 2187 when using WPA2-PSK 2188 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as 2189 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow 2190 retransmission of dropped frames) 2191 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version 2192 (e.g., segfault when processing EAPOL-Key frames) 2193 * fixed EAP workaround and fast reauthentication configuration for 2194 RSN pre-authentication; previously these were disabled and 2195 pre-authentication would fail if the used authentication server 2196 requires EAP workarounds 2197 * added support for blacklisting APs that fail or timeout 2198 authentication in ap_scan=1 mode so that all APs are tried in cases 2199 where the ones with strongest signal level are failing authentication 2200 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS 2201 authentication attempt 2202 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded 2203 in the previous authentication (previously, only Phase 1 success was 2204 verified) 2205 22062005-01-09 - v0.3.4 2207 * added preliminary support for IBSS (ad-hoc) mode configuration 2208 (mode=1 in network block); this included a new key_mgmt mode 2209 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no 2210 key management; see wpa_supplicant.conf for more details and an 2211 example on how to configure this (note: this is currently implemented 2212 only for driver_hostapd.c, but the changes should be trivial to add 2213 in associate() handler for other drivers, too (assuming the driver 2214 supports WPA-None) 2215 * added preliminary port for native Windows (i.e., no cygwin) using 2216 mingw 2217 22182005-01-02 - v0.3.3 2219 * added optional support for GNU Readline and History Libraries for 2220 wpa_cli (CONFIG_READLINE) 2221 * cleaned up EAP state machine <-> method interface and number of 2222 small problems with error case processing not terminating on 2223 EAP-Failure but waiting for timeout 2224 * added couple of workarounds for interoperability issues with a 2225 Cisco AP when using WPA2 2226 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt); 2227 Note: This requires a patch for openssl to add support for TLS 2228 extensions and number of workarounds for operations without 2229 certificates. Proof of concept type of experimental patch is 2230 included in openssl-tls-extensions.patch. 2231 22322004-12-19 - v0.3.2 2233 * fixed private key loading for cases where passphrase is not set 2234 * fixed Windows/cygwin L2 packet handler freeing; previous version 2235 could cause a segfault when RSN pre-authentication was completed 2236 * added support for PMKSA caching with drivers that generate RSN IEs 2237 (e.g., NDIS); currently, this is only implemented in driver_ndis.c, 2238 but similar code can be easily added to driver_ndiswrapper.c once 2239 ndiswrapper gets full support for RSN PMKSA caching 2240 * improved recovery from PMKID mismatches by requesting full EAP 2241 authentication in case of failed PMKSA caching attempt 2242 * driver_ndis: added support for NDIS NdisMIncidateStatus() events 2243 (this requires that ndis_events is ran while wpa_supplicant is 2244 running) 2245 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys 2246 * added support for driver interfaces to replace the interface name 2247 based on driver/OS specific mapping, e.g., in case of driver_ndis, 2248 this allows the beginning of the adapter description to be used as 2249 the interface name 2250 * added support for CR+LF (Windows-style) line ends in configuration 2251 file 2252 * driver_ndis: enable radio before starting scanning, disable radio 2253 when exiting 2254 * modified association event handler to set portEnabled = FALSE before 2255 clearing port Valid in order to reset EAP state machine and avoid 2256 problems with new authentication getting ignored because of state 2257 machines ending up in AUTHENTICATED/SUCCESS state based on old 2258 information 2259 * added support for driver events to add PMKID candidates in order to 2260 allow drivers to give priority to most likely roaming candidates 2261 * driver_hostap: moved PrivacyInvoked configuration to associate() 2262 function so that this will not be set for plaintext connections 2263 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver 2264 interface can distinguish plaintext and IEEE 802.1X (no WPA) 2265 authentication 2266 * fixed static WEP key configuration to use broadcast/default type for 2267 all keys (previously, the default TX key was configured as pairwise/ 2268 unicast key) 2269 * driver_ndis: added legacy WPA capability detection for non-WPA2 2270 drivers 2271 * added support for setting static WEP keys for IEEE 802.1X without 2272 dynamic WEP keying (eapol_flags=0) 2273 22742004-12-12 - v0.3.1 2275 * added support for reading PKCS#12 (PFX) files (as a replacement for 2276 PEM/DER) to get certificate and private key (CONFIG_PKCS12) 2277 * fixed compilation with CONFIG_PCSC=y 2278 * added new ap_scan mode, ap_scan=2, for drivers that take care of 2279 association, but need to be configured with security policy and SSID, 2280 e.g., ndiswrapper and NDIS driver; this mode should allow such 2281 drivers to work with hidden SSIDs and optimized roaming; when 2282 ap_scan=2 is used, only the first network block in the configuration 2283 file is used and this configuration should have explicit security 2284 policy (i.e., only one option in the lists) for key_mgmt, pairwise, 2285 group, proto variables 2286 * added experimental port of wpa_supplicant for Windows 2287 - driver_ndis.c driver interface (NDIS OIDs) 2288 - currently, this requires cygwin and WinPcap 2289 - small utility, win_if_list, can be used to get interface name 2290 * control interface can now be removed at build time; add 2291 CONFIG_CTRL_IFACE=y to .config to maintain old functionality 2292 * optional Xsupplicant interface can now be removed at build time; 2293 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back) 2294 * added auth_alg to driver interface associate() parameters to make it 2295 easier for drivers to configure authentication algorithm as part of 2296 the association 2297 22982004-12-05 - v0.3.0 (beginning of 0.3.x development releases) 2299 * driver_broadcom: added new driver interface for Broadcom wl.o driver 2300 (a generic driver for Broadcom IEEE 802.11a/g cards) 2301 * wpa_cli: fixed parsing of -p <path> command line argument 2302 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS 2303 ACK, not tunneled EAP-Success (of which only the first byte was 2304 actually send due to a bug in previous code); this seems to 2305 interoperate with most RADIUS servers that implements PEAPv1 2306 * PEAPv1: added support for terminating PEAP authentication on tunneled 2307 EAP-Success message; this can be configured by adding 2308 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf 2309 (some RADIUS servers require this whereas others require a tunneled 2310 reply 2311 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to 2312 the old label for key derivation; previously, the default was 1, 2313 but it looks like most existing PEAPv1 implementations use the old 2314 label which is thus more suitable default option 2315 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt) 2316 * fixed parsing of wep_tx_keyidx 2317 * added support for configuring list of allowed Phase 2 EAP types 2318 (for both EAP-PEAP and EAP-TTLS) instead of only one type 2319 * added support for configuring IEEE 802.11 authentication algorithm 2320 (auth_alg; mainly for using Shared Key authentication with static 2321 WEP keys) 2322 * added support for EAP-AKA (with UMTS SIM) 2323 * fixed couple of errors in PCSC handling that could have caused 2324 random-looking errors for EAP-SIM 2325 * added support for EAP-SIM pseudonyms and fast re-authentication 2326 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS 2327 session resumption) 2328 * added support for EAP-SIM with two challenges 2329 (phase1="sim_min_num_chal=3" can be used to require three challenges) 2330 * added support for configuring DH/DSA parameters for an ephemeral DH 2331 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters 2332 dh_file and dh_file2 (phase 2); this adds support for using DSA keys 2333 and optional DH key exchange to achieve forward secracy with RSA keys 2334 * added support for matching subject of the authentication server 2335 certificate with a substring when using EAP-TLS/PEAP/TTLS; new 2336 configuration variables subject_match and subject_match2 2337 * changed SSID configuration in driver_wext.c (used by many driver 2338 interfaces) to use ssid_len+1 as the length for SSID since some Linux 2339 drivers expect this 2340 * fixed couple of unaligned reads in scan result parsing to fix WPA 2341 connection on some platforms (e.g., ARM) 2342 * added driver interface for Intel ipw2100 driver 2343 * added support for LEAP with WPA 2344 * added support for larger scan results report (old limit was 4 kB of 2345 data, i.e., about 35 or so APs) when using Linux wireless extensions 2346 v17 or newer 2347 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start 2348 only if there is a PMKSA cache entry for the current AP 2349 * fixed error handling for case where reading of scan results fails: 2350 must schedule a new scan or wpa_supplicant will remain waiting 2351 forever 2352 * changed debug output to remove shared password/key material by 2353 default; all key information can be included with -K command line 2354 argument to match the previous behavior 2355 * added support for timestamping debug log messages (disabled by 2356 default, can be enabled with -t command line argument) 2357 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104 2358 if keys are not configured to be used; this fixes IEEE 802.1X mode 2359 with drivers that use this information to configure whether Privacy 2360 bit can be in Beacon frames (e.g., ndiswrapper) 2361 * avoid clearing driver keys if no keys have been configured since last 2362 key clear request; this seems to improve reliability of group key 2363 handshake for ndiswrapper & NDIS driver which seems to be suffering 2364 of some kind of timing issue when the keys are cleared again after 2365 association 2366 * changed driver interface API: 2367 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which 2368 version is being used (now, this is set to 2; previously, it was 2369 not defined) 2370 - pass pointer to private data structure to all calls 2371 - the new API is not backwards compatible; all in-tree driver 2372 interfaces has been converted to the new API 2373 * added support for controlling multiple interfaces (radios) per 2374 wpa_supplicant process; each interface needs to be listed on the 2375 command line (-c, -i, -D arguments) with -N as a separator 2376 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi) 2377 * added a workaround for EAP servers that incorrectly use same Id for 2378 sequential EAP packets 2379 * changed libpcap/libdnet configuration to use .config variable, 2380 CONFIG_DNET_PCAP, instead of requiring Makefile modification 2381 * improved downgrade attack detection in IE verification of msg 3/4: 2382 verify both WPA and RSN IEs, if present, not only the selected one; 2383 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or 2384 Probe Response frame, and RSN is enabled in wpa_supplicant 2385 configuration 2386 * fixed WPA msg 3/4 processing to allow Key Data field contain other 2387 IEs than just one WPA IE 2388 * added support for FreeBSD and driver interface for the BSD net80211 2389 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the 2390 required kernel mods have not yet been committed 2391 * made EAP workarounds configurable; enabled by default, can be 2392 disabled with network block option eap_workaround=0 2393 23942004-07-17 - v0.2.4 (beginning of 0.2.x stable releases) 2395 * resolved couple of interoperability issues with EAP-PEAPv1 and 2396 Phase 2 (inner EAP) fragment reassembly 2397 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the 2398 AP is using non-zero key index for the unicast key and key index zero 2399 for the broadcast key 2400 * driver_hostap: fixed IEEE 802.1X WEP key updates and 2401 re-authentication by allowing unencrypted EAPOL frames when not using 2402 WPA 2403 * added a new driver interface, 'wext', which uses only standard, 2404 driver independent functionality in Linux wireless extensions; 2405 currently, this can be used only for non-WPA IEEE 802.1X mode, but 2406 eventually, this is to be extended to support full WPA/WPA2 once 2407 Linux wireless extensions get support for this 2408 * added support for mode in which the driver is responsible for AP 2409 scanning and selection; this is disabled by default and can be 2410 enabled with global ap_scan=0 variable in wpa_supplicant.conf; 2411 this mode can be used, e.g., with generic 'wext' driver interface to 2412 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver 2413 supporting wireless extensions. 2414 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g., 2415 operation with an AP that does not include SSID in the Beacon frames) 2416 * added support for new EAP authentication methods: 2417 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP 2418 * added support for asking one-time-passwords from frontends (e.g., 2419 wpa_cli); this 'otp' command works otherwise like 'password' command, 2420 but the password is used only once and the frontend will be asked for 2421 a new password whenever a request from authenticator requires a 2422 password; this can be used with both EAP-OTP and EAP-GTC 2423 * changed wpa_cli to automatically re-establish connection so that it 2424 does not need to be re-started when wpa_supplicant is terminated and 2425 started again 2426 * improved user data (identity/password/otp) requests through 2427 frontends: process pending EAPOL packets after getting new 2428 information so that full authentication does not need to be 2429 restarted; in addition, send pending requests again whenever a new 2430 frontend is attached 2431 * changed control frontends to use a new directory for socket files to 2432 make it easier for wpa_cli to automatically select between interfaces 2433 and to provide access control for the control interface; 2434 wpa_supplicant.conf: ctrl_interface is now a path 2435 (/var/run/wpa_supplicant is the recommended path) and 2436 ctrl_interface_group can be used to select which group gets access to 2437 the control interface; 2438 wpa_cli: by default, try to connect to the first interface available 2439 in /var/run/wpa_supplicant; this path can be overridden with -p option 2440 and an interface can be selected with -i option (i.e., in most common 2441 cases, wpa_cli does not need to get any arguments) 2442 * added support for LEAP 2443 * added driver interface for Linux ndiswrapper 2444 * added priority option for network blocks in the configuration file; 2445 this allows networks to be grouped based on priority (the scan 2446 results are searched for matches with network blocks in this order) 2447 24482004-06-20 - v0.2.3 2449 * sort scan results to improve AP selection 2450 * fixed control interface socket removal for some error cases 2451 * improved scan requesting and authentication timeout 2452 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and 2453 TLS processing 2454 * PEAP version can now be forced with phase1="peapver=<ver>" 2455 (mostly for testing; by default, the highest version supported by 2456 both the Supplicant and Authentication Server is selected 2457 automatically) 2458 * added support for madwifi driver (Atheros ar521x) 2459 * added a workaround for cases where AP sets Install Tx/Rx bit for 2460 WPA Group Key messages when pairwise keys are used (without this, 2461 the Group Key would be used for Tx and the AP would drop frames 2462 from the station) 2463 * added GSM SIM/USIM interface for GSM authentication algorithm for 2464 EAP-SIM; this requires pcsc-lite 2465 * added support for ATMEL AT76C5XXx driver 2466 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator 2467 does not include key data in the EAPOL-Key frame (i.e., part of 2468 EAP keying material is used as data encryption key) 2469 * added support for using plaintext and static WEP networks 2470 (key_mgmt=NONE) 2471 24722004-05-31 - v0.2.2 2473 * added support for new EAP authentication methods: 2474 EAP-TTLS/EAP-MD5-Challenge 2475 EAP-TTLS/EAP-GTC 2476 EAP-TTLS/EAP-MSCHAPv2 2477 EAP-TTLS/EAP-TLS 2478 EAP-TTLS/MSCHAPv2 2479 EAP-TTLS/MSCHAP 2480 EAP-TTLS/PAP 2481 EAP-TTLS/CHAP 2482 EAP-PEAP/TLS 2483 EAP-PEAP/GTC 2484 EAP-PEAP/MD5-Challenge 2485 EAP-GTC 2486 EAP-SIM (not yet complete; needs GSM/SIM authentication interface) 2487 * added support for anonymous identity (to be used when identity is 2488 sent in plaintext; real identity will be used within TLS protected 2489 tunnel (e.g., with EAP-TTLS) 2490 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli 2491 * added support for requesting identity and password information using 2492 control interface; in other words, the password for EAP-PEAP or 2493 EAP-TTLS does not need to be included in the configuration file since 2494 a frontand (e.g., wpa_cli) can ask it from the user 2495 * improved RSN pre-authentication to use a candidate list and process 2496 all candidates from each scan; not only one per scan 2497 * fixed RSN IE and WPA IE capabilities field parsing 2498 * ignore Tx bit in GTK IE when Pairwise keys are used 2499 * avoid making new scan requests during IEEE 802.1X negotiation 2500 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant 2501 with TLS support (this replaces the included implementation with 2502 library code to save about 8 kB since the library code is needed 2503 anyway for TLS) 2504 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support 2505 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config) 2506 25072004-05-06 - v0.2.1 2508 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1) 2509 Supplicant 2510 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1] 2511 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf] 2512 - EAP-MD5 (cannot be used with WPA-RADIUS) 2513 [draft-ietf-eap-rfc2284bis-09.txt] 2514 - EAP-TLS [RFC 2716] 2515 - EAP-MSCHAPv2 (currently used only with EAP-PEAP) 2516 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt] 2517 [draft-kamath-pppext-eap-mschapv2-00.txt] 2518 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by 2519 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey) 2520 - new configuration file options: eap, identity, password, ca_cert, 2521 client_cert, privatekey, private_key_passwd 2522 - Xsupplicant is not required anymore, but it can be used by 2523 disabling the internal IEEE 802.1X Supplicant with -e command line 2524 option 2525 - this code is not included in the default build; Makefile need to 2526 be edited for this (uncomment lines for selected functionality) 2527 - EAP-TLS and EAP-PEAP require openssl libraries 2528 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..) 2529 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys 2530 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X 2531 EAPOL-Key frames instead of WPA key handshakes) 2532 * added support for IEEE 802.11i/RSN (WPA2) 2533 - improved PTK Key Handshake 2534 - PMKSA caching, pre-authentication 2535 * fixed wpa_supplicant to ignore possible extra data after WPA 2536 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using 2537 TPTK' error from message 3 of 4-Way Handshake in case the AP 2538 includes extra data after the EAPOL-Key) 2539 * added interface for external programs (frontends) to control 2540 wpa_supplicant 2541 - CLI example (wpa_cli) with interactive mode and command line 2542 mode 2543 - replaced SIGUSR1 status/statistics with the new control interface 2544 * made some feature compile time configurable 2545 - .config file for make 2546 - driver interfaces (hostap, hermes, ..) 2547 - EAPOL/EAP functions 2548 25492004-02-15 - v0.2.0 2550 * Initial version of wpa_supplicant 2551
