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