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