1014 (p2p_no_group_iface=1)
1015 * fixed P2P Bonjour SD to match entries with both compressed and not
1016 compressed domain name format and support multiple Bonjour PTR matches
1017 for the same key

1034 * bsd: Add support for setting HT values in IFM_MMASK.
1035 * Delay STA entry removal until Deauth/Disassoc TX status in AP mode.
1036 This allows the driver to use PS buffering of Deauthentication and
1037 Disassociation frames when the STA is in power save sleep. Only
1038 available with drivers that provide TX status events for Deauth/
1039 Disassoc frames (nl80211).

1050 the data connection is not working properly, e.g., due to the STA
1051 going outside the range of the AP). Disabled by default, enable by
1052 config option disassoc_low_ack.
1053 * nl80211:
1054 - Support GTK rekey offload.
1055 - Support PMKSA candidate events. This adds support for RSN

1070 - Emit property changed events (for property BSSs) when adding/
1071 removing BSSs.
1072 - Treat '' in SSIDs of Interface.Scan as a request for broadcast
1073 scan, instead of ignoring it.

1082 - Add bss_expire_age and bss_expire_count commands to set/get BSS
1083 cache expiration age and expiration scan count.
1084 - Add ability to set scan interval (the time in seconds wpa_s waits
1085 before requesting a new scan after failing to find a suitable
1086 network in scan results) using scan_interval command.
1087 - Add event CTRL-EVENT-ASSOC-REJECT for association rejected.
1088 - Add command get version, that returns wpa_supplicant version string.
1089 - Add command sta_autoconnect for disabling automatic reconnection
1090 on receiving disconnection event.
1091 - Setting bssid parameter to an empty string "" or any can now be
1092 used to clear the bssid_set flag in a network block, i.e., to remove
1093 bssid filtering.
1094 - Add tdls_testing command to add a special testing feature for
1095 changing TDLS behavior. Build param CONFIG_TDLS_TESTING must be
1096 enabled as well.

1106 - Add internal line edit implementation. CONFIG_WPA_CLI_EDIT=y
1107 can now be used to build wpa_cli with internal implementation of
1108 line editing and history support. This can be used as a replacement
1109 for CONFIG_READLINE=y.
1110 * AP mode: Add max_num_sta config option, which can be used to limit
1111 the number of stations allowed to connect to the AP.

1129 validate the checksum digit (if present).
1130 - Cancel WPS operation on PBC session overlap detection.
1131 - New wps_cancel command in wpa_cli will cancel a pending WPS
1132 operation.
1133 - wpa_cli action: Add WPS_EVENT_SUCCESS and WPS_EVENT_FAIL handlers.
1134 - Trigger WPS config update on Manufacturer, Model Name, Model
1135 Number, and Serial Number changes.
1136 - Fragment size is now configurable for EAP-WSC peer. Use
1137 wpa_cli set wps_fragment_size <val>.
1138 - Disable AP PIN after 10 consecutive failures. Slow down attacks on
1139 failures up to 10.
1140 - Allow AP to start in Enrollee mode without AP PIN for probing, to
1141 be compatible with Windows 7.
1142 - Add Config Error into WPS-FAIL events to provide more info to the
1143 user on how to resolve the issue.
1144 - Label and Display config methods are not allowed to be enabled
1145 at the same time, since it is unclear which PIN to use if both
1146 methods are advertised.
1147 - When controlling multiple interfaces:
1148 - apply WPS commands to all interfaces configured to use WPS
1149 - apply WPS config changes to all interfaces that use WPS
1150 - when an attack is detected on any interface, disable AP PIN on
1151 all interfaces
1152 * WPS ER:
1153 - Add special AP Setup Locked mode to allow read only ER.
1154 ap_setup_locked=2 can now be used to enable a special mode where
1155 WPS ER can learn the current AP settings, but cannot change them.
1156 - Show SetSelectedRegistrar events as ctrl_iface events
1157 - Add wps_er_set_config to enroll a network based on a local
1158 network configuration block instead of having to (re-)learn the
1159 current AP settings with wps_er_learn.
1160 - Allow AP filtering based on IP address, add ctrl_iface event for
1161 learned AP settings, add wps_er_config command to configure an AP.

1168 * TDLS:
Hai Shalom60840252021-02-19 19:02:11 -08001169 - Propagate TDLS related nl80211 capability flags from kernel and
Dmitry Shmidt04949592012-07-19 12:16:46 -07001170 add them as driver capability flags. If the driver doesn't support
1171 capabilities, assume TDLS is supported internally. When TDLS is
1172 explicitly not supported, disable all user facing TDLS operations.
1173 - Allow TDLS to be disabled at runtime (mostly for testing).
1174 Use set tdls_disabled.
1175 - Honor AP TDLS settings that prohibit/allow TDLS.
1176 - Add a special testing feature for changing TDLS behavior. Use
1177 CONFIG_TDLS_TESTING build param to enable. Configure at runtime

1187 and stop_fetch_anqp.
1188 * Android: Add build and runtime support for Android wpa_supplicant.
1189 * bgscan learn: Add new bgscan that learns BSS information based on
1190 previous scans, and uses that information to dynamically generate
1191 the list of channels for background scans.

1206
Dmitry Shmidt8d520ff2011-05-09 14:06:53 -070012072010-04-18 - v0.7.2
1208 * nl80211: fixed number of issues with roaming
1209 * avoid unnecessary roaming if multiple APs with similar signal
1210 strength are present in scan results
1211 * add TLS client events and server probing to ease design of
1212 automatic detection of EAP parameters
1213 * add option for server certificate matching (SHA256 hash of the
1214 certificate) instead of trusted CA certificate configuration
1215 * bsd: Cleaned up driver wrapper and added various low-level
1216 configuration options
1217 * wpa_gui-qt4: do not show too frequent WPS AP available events as
1218 tray messages
1219 * TNC: fixed issues with fragmentation
1220 * EAP-TNC: add Flags field into fragment acknowledgement (needed to
1221 interoperate with other implementations; may potentially breaks
1222 compatibility with older wpa_supplicant/hostapd versions)
1223 * wpa_cli: added option for using a separate process to receive event
1224 messages to reduce latency in showing these
1225 (CFLAGS += -DCONFIG_WPA_CLI_FORK=y in .config to enable this)
1226 * maximum BSS table size can now be configured (bss_max_count)
1227 * BSSes to be included in the BSS table can be filtered based on
1228 configured SSIDs to save memory (filter_ssids)
1229 * fix number of issues with IEEE 802.11r/FT; this version is not
1230 backwards compatible with old versions
1231 * nl80211: add support for IEEE 802.11r/FT protocol (both over-the-air
1232 and over-the-DS)
1233 * add freq_list network configuration parameter to allow the AP
1234 selection to filter out entries based on the operating channel
1235 * add signal strength change events for bgscan; this allows more
1236 dynamic changes to background scanning interval based on changes in
1237 the signal strength with the current AP; this improves roaming within
1238 ESS quite a bit, e.g., with bgscan="simple:30:-45:300" in the network
1239 configuration block to request background scans less frequently when
1240 signal strength remains good and to automatically trigger background
1241 scans whenever signal strength drops noticeably
1242 (this is currently only available with nl80211)
1243 * add BSSID and reason code (if available) to disconnect event messages
1244 * wpa_gui-qt4: more complete support for translating the GUI with
1245 linguist and add German translation
1246 * fix DH padding with internal crypto code (mainly, for WPS)
1247 * do not trigger initial scan automatically anymore if there are no
1248 enabled networks
1249
12502010-01-16 - v0.7.1
1251 * cleaned up driver wrapper API (struct wpa_driver_ops); the new API
1252 is not fully backwards compatible, so out-of-tree driver wrappers
1253 will need modifications
1254 * cleaned up various module interfaces
1255 * merge hostapd and wpa_supplicant developers' documentation into a
1256 single document
1257 * nl80211: use explicit deauthentication to clear cfg80211 state to
1258 avoid issues when roaming between APs
1259 * dbus: major design changes in the new D-Bus API
1260 (fi.w1.wpa_supplicant1)
1261 * nl80211: added support for IBSS networks
1262 * added internal debugging mechanism with backtrace support and memory
1263 allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y)
1264 * added WPS ER unsubscription command to more cleanly unregister from
1265 receiving UPnP events when ER is terminated
1266 * cleaned up AP mode operations to avoid need for virtual driver_ops
1267 wrapper
1268 * added BSS table to maintain more complete scan result information
1269 over multiple scans (that may include only partial results)
1270 * wpa_gui-qt4: update Peers dialog information more dynamically while
1271 the dialog is kept open
1272 * fixed PKCS#12 use with OpenSSL 1.0.0
1273 * driver_wext: Added cfg80211-specific optimization to avoid some
1274 unnecessary scans and to speed up association
1275
12762009-11-21 - v0.7.0
1277 * increased wpa_cli ping interval to 5 seconds and made this
1278 configurable with a new command line options (-G<seconds>)
1279 * fixed scan buffer processing with WEXT to handle up to 65535
1280 byte result buffer (previously, limited to 32768 bytes)
1281 * allow multiple driver wrappers to be specified on command line
1282 (e.g., -Dnl80211,wext); the first one that is able to initialize the
1283 interface will be used
1284 * added support for multiple SSIDs per scan request to optimize
1285 scan_ssid=1 operations in ap_scan=1 mode (i.e., search for hidden
1286 SSIDs); this requires driver support and can currently be used only
1287 with nl80211
1288 * added support for WPS USBA out-of-band mechanism with USB Flash
1289 Drives (UFD) (CONFIG_WPS_UFD=y)
1290 * driver_ndis: add PAE group address to the multicast address list to
1291 fix wired IEEE 802.1X authentication
1292 * fixed IEEE 802.11r key derivation function to match with the standard
1293 (note: this breaks interoperability with previous version) [Bug 303]
1294 * added better support for drivers that allow separate authentication
1295 and association commands (e.g., mac80211-based Linux drivers with
1296 nl80211; SME in wpa_supplicant); this allows over-the-air FT protocol
1297 to be used (IEEE 802.11r)
1298 * fixed SHA-256 based key derivation function to match with the
1299 standard when using CCMP (for IEEE 802.11r and IEEE 802.11w)
1300 (note: this breaks interoperability with previous version) [Bug 307]
1301 * use shared driver wrapper files with hostapd
1302 * added AP mode functionality (CONFIG_AP=y) with mode=2 in the network
1303 block; this can be used for open and WPA2-Personal networks
1304 (optionally, with WPS); this links in parts of hostapd functionality
1305 into wpa_supplicant
1306 * wpa_gui-qt4: added new Peers dialog to show information about peers
1307 (other devices, including APs and stations, etc. in the neighborhood)
1308 * added support for WPS External Registrar functionality (configure APs
1309 and enroll new devices); can be used with wpa_gui-qt4 Peers dialog
1310 and wpa_cli commands wps_er_start, wps_er_stop, wps_er_pin,
1311 wps_er_pbc, wps_er_learn
1312 (this can also be used with a new 'none' driver wrapper if no
1313 wireless device or IEEE 802.1X on wired is needed)
1314 * driver_nl80211: multiple updates to provide support for new Linux
1315 nl80211/mac80211 functionality
1316 * updated management frame protection to use IEEE Std 802.11w-2009
1317 * fixed number of small WPS issues and added workarounds to
1318 interoperate with common deployed broken implementations
1319 * added support for NFC out-of-band mechanism with WPS
1320 * driver_ndis: fixed wired IEEE 802.1X authentication with PAE group
1321 address frames
1322 * added preliminary support for IEEE 802.11r RIC processing
1323 * added support for specifying subset of enabled frequencies to scan
1324 (scan_freq option in the network configuration block); this can speed
1325 up scanning process considerably if it is known that only a small
1326 subset of channels is actually used in the network (this is currently
1327 supported only with -Dnl80211)
1328 * added a workaround for race condition between receiving the
1329 association event and the following EAPOL-Key
1330 * added background scan and roaming infrastructure to allow
1331 network-specific optimizations to be used to improve roaming within
1332 an ESS (same SSID)
1333 * added new DBus interface (fi.w1.wpa_supplicant1)
1334
13352009-01-06 - v0.6.7
1336 * added support for Wi-Fi Protected Setup (WPS)
1337 (wpa_supplicant can now be configured to act as a WPS Enrollee to
1338 enroll credentials for a network using PIN and PBC methods; in
1339 addition, wpa_supplicant can act as a wireless WPS Registrar to
1340 configure an AP); WPS support can be enabled by adding CONFIG_WPS=y
1341 into .config and setting the runtime configuration variables in
1342 wpa_supplicant.conf (see WPS section in the example configuration
1343 file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to
1344 manage WPS negotiation; see README-WPS for more details
1345 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
1346 * added support for using driver_test over UDP socket
1347 * fixed PEAPv0 Cryptobinding interoperability issue with Windows Server
1348 2008 NPS; optional cryptobinding is now enabled (again) by default
1349 * fixed PSK editing in wpa_gui
1350 * changed EAP-GPSK to use the IANA assigned EAP method type 51
1351 * added a Windows installer that includes WinPcap and all the needed
1352 DLLs; in addition, it set up the registry automatically so that user
1353 will only need start wpa_gui to get prompted to start the wpasvc
1354 servide and add a new interface if needed through wpa_gui dialog
1355 * updated management frame protection to use IEEE 802.11w/D7.0
1356
13572008-11-23 - v0.6.6
1358 * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
1359 (can be used to simulate test SIM/USIM card with a known private key;
1360 enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
1361 and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
1362 * added a new network configuration option, wpa_ptk_rekey, that can be
1363 used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
1364 against TKIP deficiencies
1365 * added an optional mitigation mechanism for certain attacks against
1366 TKIP by delaying Michael MIC error reports by a random amount of time
1367 between 0 and 60 seconds; this can be enabled with a build option
1368 CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
1369 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
1370 not bytes
1371 * updated OpenSSL code for EAP-FAST to use an updated version of the
1372 session ticket overriding API that was included into the upstream
1373 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
1374 needed with that version anymore)
1375 * updated userspace MLME instructions to match with the current Linux
1376 mac80211 implementation; please also note that this can only be used
1377 with driver_nl80211.c (the old code from driver_wext.c was removed)
1378 * added support (Linux only) for RoboSwitch chipsets (often found in
1379 consumer grade routers); driver interface 'roboswitch'
1380 * fixed canceling of PMKSA caching when using drivers that generate
1381 RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
1382 about
1383
13842008-11-01 - v0.6.5
1385 * added support for SHA-256 as X.509 certificate digest when using the
1386 internal X.509/TLSv1 implementation
1387 * updated management frame protection to use IEEE 802.11w/D6.0
1388 * added support for using SHA256-based stronger key derivation for WPA2
1389 (IEEE 802.11w)
1390 * fixed FT (IEEE 802.11r) authentication after a failed association to
1391 use correct FTIE
1392 * added support for configuring Phase 2 (inner/tunneled) authentication
1393 method with wpa_gui-qt4
1394
13952008-08-10 - v0.6.4
1396 * added support for EAP Sequences in EAP-FAST Phase 2
1397 * added support for using TNC with EAP-FAST
1398 * added driver_ps3 for the PS3 Linux wireless driver
1399 * added support for optional cryptobinding with PEAPv0
1400 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
1401 allow fallback to full handshake if server rejects PAC-Opaque
1402 * added fragmentation support for EAP-TNC
1403 * added support for parsing PKCS #8 formatted private keys into the
1404 internal TLS implementation (both PKCS #1 RSA key and PKCS #8
1405 encapsulated RSA key can now be used)
1406 * added option of using faster, but larger, routines in the internal
1407 LibTomMath (for internal TLS implementation) to speed up DH and RSA
1408 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
1409 * fixed race condition between disassociation event and group key
1410 handshake to avoid getting stuck in incorrect state [Bug 261]
1411 * fixed opportunistic key caching (proactive_key_caching)
1412
14132008-02-22 - v0.6.3
1414 * removed 'nai' and 'eappsk' network configuration variables that were
1415 previously used for configuring user identity and key for EAP-PSK,
1416 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
1417 replacement for 'nai' (if old configuration used a separate
1418 'identity' value, that would now be configured as
1419 'anonymous_identity'). 'password' field is now used as the
1420 replacement for 'eappsk' (it can also be set using hexstring to
1421 present random binary data)
1422 * removed '-w' command line parameter (wait for interface to be added,
1423 if needed); cleaner way of handling this functionality is to use an
1424 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
1425 when an interface is added
1426 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
1427 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
1428 indicating when new scan results become available
1429 * added new ctrl_iface command, BSS, to allow scan results to be
1430 fetched without hitting the message size limits (this command
1431 can be used to iterate through the scan results one BSS at the time)
1432 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
1433 attributes in EAP-SIM Start/Response when using fast reauthentication
1434 * fixed EAPOL not to end up in infinite loop when processing dynamic
1435 WEP keys with IEEE 802.1X
1436 * fixed problems in getting NDIS events from WMI on Windows 2000
1437
14382008-01-01 - v0.6.2
1439 * added support for Makefile builds to include debug-log-to-a-file
1440 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
1441 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
1442 lengths properly to avoid potential crash caused by invalid messages
1443 * added data structure for storing allocated buffers (struct wpabuf);
1444 this does not affect wpa_supplicant usage, but many of the APIs
1445 changed and various interfaces (e.g., EAP) is not compatible with old
1446 versions
1447 * added support for protecting EAP-AKA/Identity messages with
1448 AT_CHECKCODE (optional feature in RFC 4187)
1449 * added support for protected result indication with AT_RESULT_IND for
1450 EAP-SIM and EAP-AKA (phase1="result_ind=1")
1451 * added driver_wext workaround for race condition between scanning and
1452 association with drivers that take very long time to scan all
1453 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
1454 using a longer hardcoded timeout for the scan if the driver supports
1455 notifications for scan completion (SIOCGIWSCAN event); this helps,
1456 e.g., in cases where wpa_supplicant and madwifi driver ended up in
1457 loop where the driver did not even try to associate
1458 * stop EAPOL timer tick when no timers are in use in order to reduce
1459 power consumption (no need to wake up the process once per second)
1460 [Bug 237]
1461 * added support for privilege separation (run only minimal part of
1462 wpa_supplicant functionality as root and rest as unprivileged,
1463 non-root process); see 'Privilege separation' in README for details;
1464 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
1465 in .config
1466 * changed scan results data structure to include all information
1467 elements to make it easier to support new IEs; old get_scan_result()
1468 driver_ops is still supported for backwards compatibility (results
1469 are converted internally to the new format), but all drivers should
1470 start using the new get_scan_results2() to make them more likely to
1471 work with new features
1472 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
1473 application, i.e., it does not require Qt3Support anymore; Windows
1474 binary of wpa_gui.exe is now from this directory and only requires
1475 QtCore4.dll and QtGui4.dll libraries
1476 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
1477 available as a separate package to make wpa_gui installation easier:
1478 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
1479 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
1480 only shared key/password authentication is supported in this version
1481
14822007-11-24 - v0.6.1
1483 * added support for configuring password as NtPasswordHash
1484 (16-byte MD4 hash of password) in hash:<32 hex digits> format
1485 * added support for fallback from abbreviated TLS handshake to
1486 full handshake when using EAP-FAST (e.g., due to an expired
1487 PAC-Opaque)
1488 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
1489 draft (draft-ietf-emu-eap-gpsk-07.txt)
1490 * added support for drivers that take care of RSN 4-way handshake
1491 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
1492 WPA_ALG_PMK in set_key)
1493 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
1494 .config); this version supports only ap_scan=2 mode and allow the
1495 driver to take care of the 4-way handshake
1496 * fixed a buffer overflow in parsing TSF from scan results when using
1497 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
1498 [Bug 232]
1499 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
1500 * fixed an integer overflow issue in the ASN.1 parser used by the
1501 (experimental) internal TLS implementation to avoid a potential
1502 buffer read overflow
1503 * fixed a race condition with -W option (wait for a control interface
1504 monitor before starting) that could have caused the first messages to
1505 be lost
1506 * added support for processing TNCC-TNCS-Messages to report
1507 recommendation (allow/none/isolate) when using TNC [Bug 243]
1508
15092007-05-28 - v0.6.0
1510 * added network configuration parameter 'frequency' for setting
1511 initial channel for IBSS (adhoc) networks
1512 * added experimental IEEE 802.11r/D6.0 support
1513 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
1514 * updated EAP-PSK to use the IANA-allocated EAP type 47
1515 * fixed EAP-PAX key derivation
1516 * fixed EAP-PSK bit ordering of the Flags field
1517 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
1518 tunnelled identity request (previously, the identifier from the outer
1519 method was used, not the tunnelled identifier which could be
1520 different)
1521 * added support for fragmentation of outer TLS packets during Phase 2
1522 of EAP-PEAP/TTLS/FAST
1523 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
1524 * added support for EAP-FAST authentication with inner methods that
1525 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
1526 for PAC provisioning)
1527 * added support for authenticated EAP-FAST provisioning
1528 * added support for configuring maximum number of EAP-FAST PACs to
1529 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
1530 * added support for storing EAP-FAST PACs in binary format
1531 (fast_pac_format=binary in phase1 string)
1532 * fixed dbus ctrl_iface to validate message interface before
1533 dispatching to avoid a possible segfault [Bug 190]
1534 * fixed PeerKey key derivation to use the correct PRF label
1535 * updated Windows binary build to link against OpenSSL 0.9.8d and
1536 added support for EAP-FAST
1537 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
1538 draft (draft-ietf-emu-eap-gpsk-04.txt)
1539 * fixed EAP-AKA Notification processing to allow Notification to be
1540 processed after AKA Challenge response has been sent
1541 * updated to use IEEE 802.11w/D2.0 for management frame protection
1542 (still experimental)
1543 * fixed EAP-TTLS implementation not to crash on use of freed memory
1544 if TLS library initialization fails
1545 * added support for EAP-TNC (Trusted Network Connect)
1546 (this version implements the EAP-TNC method and EAP-TTLS changes
1547 needed to run two methods in sequence (IF-T) and the IF-IMC and
1548 IF-TNCCS interfaces from TNCC)
1549
15502006-11-24 - v0.5.6
1551 * added experimental, integrated TLSv1 client implementation with the
1552 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
1553 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
1554 .config); this can be useful, e.g., if the target system does not
1555 have a suitable TLS library and a minimal code size is required
1556 (total size of this internal TLS/crypto code is bit under 50 kB on
1557 x86 and the crypto code is shared by rest of the supplicant so some
1558 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
1559 * removed STAKey handshake since PeerKey handshake has replaced it in
1560 IEEE 802.11ma and there are no known deployments of STAKey
1561 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
1562 draft (draft-ietf-emu-eap-gpsk-01.txt)
1563 * added preliminary implementation of IEEE 802.11w/D1.0 (management
1564 frame protection)
1565 (Note: this requires driver support to work properly.)
1566 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
1567 * fixed Windows named pipes ctrl_iface to not stop listening for
1568 commands if client program opens a named pipe and closes it
1569 immediately without sending a command
1570 * fixed USIM PIN status determination for the case that PIN is not
1571 needed (this allows EAP-AKA to be used with USIM cards that do not
1572 use PIN)
1573 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
1574 be used with cards that do not support file selection based on
1575 partial AID
1576 * added support for matching the subjectAltName of the authentication
1577 server certificate against multiple name components (e.g.,
1578 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
1579 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
1580 affects IEEE 802.1X with dynamic WEP keys)
1581 * changed ctrl_iface network configuration 'get' operations to not
1582 return password/key material; if these fields are requested, "*"
1583 will be returned if the password/key is set, but the value of the
1584 parameter is not exposed
1585
15862006-08-27 - v0.5.5
1587 * added support for building Windows version with UNICODE defined
1588 (wide-char functions)
1589 * driver_ndis: fixed static WEP configuration to avoid race condition
1590 issues with some NDIS drivers between association and setting WEP
1591 keys
1592 * driver_ndis: added validation for IELength value in scan results to
1593 avoid crashes when using buggy NDIS drivers [Bug 165]
1594 * fixed Release|Win32 target in the Visual Studio project files
1595 (previously, only Debug|Win32 target was set properly)
1596 * changed control interface API call wpa_ctrl_pending() to allow it to
1597 return -1 on error (e.g., connection lost); control interface clients
1598 will need to make sure that they verify that the value is indeed >0
1599 when determining whether there are pending messages
1600 * added an alternative control interface backend for Windows targets:
1601 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
1602 control interface mechanism for Windows builds (previously, UDP to
1603 localhost was used)
1604 * changed ctrl_interface configuration for UNIX domain sockets:
1605 - deprecated ctrl_interface_group variable (it may be removed in
1606 future versions)
1607 - allow both directory and group be configured with ctrl_interface
1608 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
1609 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
1610 case when group is not changed
1611 * added support for controlling more than one interface per process in
1612 Windows version
1613 * added a workaround for a case where the AP is using unknown address
1614 (e.g., MAC address of the wired interface) as the source address for
1615 EAPOL-Key frames; previously, that source address was used as the
1616 destination for EAPOL-Key frames and in key derivation; now, BSSID is
1617 used even if the source address does not match with it
1618 (this resolves an interoperability issue with Thomson SpeedTouch 580)
1619 * added a workaround for UDP-based control interface (which was used in
1620 Windows builds before this release) to prevent packets with forged
1621 addresses from being accepted as local control requests
1622 * removed ndis_events.cpp and possibility of using external
1623 ndis_events.exe; C version (ndis_events.c) is fully functional and
1624 there is no desire to maintain two separate versions of this
1625 implementation
1626 * ndis_events: Changed NDIS event notification design to use WMI to
1627 learn the adapter description through Win32_PnPEntity class; this
1628 should fix some cases where the adapter name was not recognized
1629 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
1630 USB) [Bug 113]
1631 * fixed selection of the first network in ap_scan=2 mode; previously,
1632 wpa_supplicant could get stuck in SCANNING state when only the first
1633 network for enabled (e.g., after 'wpa_cli select_network 0')
1634 * winsvc: added support for configuring ctrl_interface parameters in
1635 registry (ctrl_interface string value in
1636 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
1637 required to enable control interface (previously, this was hardcoded
1638 to be enabled)
1639 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
1640 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
1641
16422006-06-20 - v0.5.4
1643 * fixed build with CONFIG_STAKEY=y [Bug 143]
1644 * added support for doing MLME (IEEE 802.11 management frame
1645 processing) in wpa_supplicant when using Devicescape IEEE 802.11
1646 stack (wireless-dev.git tree)
1647 * added a new network block configuration option, fragment_size, to
1648 configure the maximum EAP fragment size
1649 * driver_ndis: Disable WZC automatically for the selected interface to
1650 avoid conflicts with two programs trying to control the radio; WZC
1651 will be re-enabled (if it was enabled originally) when wpa_supplicant
1652 is terminated
1653 * added an experimental TLSv1 client implementation
1654 (CONFIG_TLS=internal) that can be used instead of an external TLS
1655 library, e.g., to reduce total size requirement on systems that do
1656 not include any TLS library by default (this is not yet complete;
1657 basic functionality is there, but certificate validation is not yet
1658 included)
1659 * added PeerKey handshake implementation for IEEE 802.11e
1660 direct link setup (DLS) to replace STAKey handshake
1661 * fixed WPA PSK update through ctrl_iface for the case where the old
1662 PSK was derived from an ASCII passphrase and the new PSK is set as
1663 a raw PSK (hex string)
1664 * added new configuration option for identifying which network block
1665 was used (id_str in wpa_supplicant.conf; included on
1666 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
1667 variable in wpa_cli action scripts; in addition WPA_ID variable is
1668 set to the current unique identifier that wpa_supplicant assigned
1669 automatically for the network and that can be used with
1670 GET_NETWORK/SET_NETWORK ctrl_iface commands)
1671 * wpa_cli action script is now called only when the connect/disconnect
1672 status changes or when associating with a different network
1673 * fixed configuration parser not to remove CCMP from group cipher list
1674 if WPA-None (adhoc) is used (pairwise=NONE in that case)
1675 * fixed integrated NDIS events processing not to hang the process due
1676 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
1677 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
1678 draft-clancy-emu-eap-shared-secret-00.txt)
1679 * added Microsoft Visual Studio 2005 solution and project files for
1680 build wpa_supplicant for Windows (see vs2005 subdirectory)
1681 * eloop_win: fixed unregistration of Windows events
1682 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
1683 at the end of RSN pre-authentication and added unregistration of
1684 a Windows event to avoid getting eloop_win stuck with an invalid
1685 handle
1686 * driver_ndis: added support for selecting AP based on BSSID
1687 * added new environmental variable for wpa_cli action scripts:
1688 WPA_CTRL_DIR is the current control interface directory
1689 * driver_ndis: added support for using NDISUIO instead of WinPcap for
1690 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
1691 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
1692 wpa_supplicant without requiring WinPcap; note that using NDISUIO
1693 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
1694 only one application to open the device
1695 * changed NDIS driver naming to only include device GUID, e.g.,
1696 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
1697 specific \Device\NPF_ prefix before the GUID; the prefix is still
1698 allowed for backwards compatibility, but it is not required anymore
1699 when specifying the interface
1700 * driver_ndis: re-initialize driver interface is the adapter is removed
1701 and re-inserted [Bug 159]
1702 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
1703 big endian hosts [Bug 146]
1704
17052006-04-27 - v0.5.3
1706 * fixed EAP-GTC response to include correct user identity when run as
1707 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
1708 * driver_ndis: Fixed encryption mode configuration for unencrypted
1709 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
1710 refused to associate with open networks) [Bug 106]
1711 * driver_ndis: use BSSID OID polling to detect when IBSS network is
1712 formed even when ndis_events code is included since some NDIS drivers
1713 do not generate media connect events in IBSS mode
1714 * config_winreg: allow global ctrl_interface parameter to be configured
1715 in Windows registry
1716 * config_winreg: added support for saving configuration data into
1717 Windows registry
1718 * added support for controlling network device operational state
1719 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
1720 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
1721 that can use this information)
1722 * driver_wext: added support for WE-21 change to SSID configuration
1723 * driver_wext: fixed privacy configuration for static WEP keys mode
1724 [Bug 140]
1725 * added an optional driver_ops callback for MLME-SETPROTECTION.request
1726 primitive
1727 * added support for EAP-SAKE (no EAP method number allocated yet, so
1728 this is using the same experimental type 255 as EAP-PSK)
1729 * added support for dynamically loading EAP methods (.so files) instead
1730 of requiring them to be statically linked in; this is disabled by
1731 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
1732 on how to use this)
1733
17342006-03-19 - v0.5.2
1735 * do not try to use USIM APDUs when initializing PC/SC for SIM card
1736 access for a network that has not enabled EAP-AKA
1737 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
1738 v0.5.1 due to the new support for expanded EAP types)
1739 * added support for generating EAP Expanded Nak
1740 * try to fetch scan results once before requesting new scan when
1741 starting up in ap_scan=1 mode (this can speed up initial association
1742 a lot with, e.g., madwifi-ng driver)
1743 * added support for receiving EAPOL frames from a Linux bridge
1744 interface (-bbr0 on command line)
1745 * fixed EAPOL re-authentication for sessions that used PMKSA caching
1746 * changed EAP method registration to use a dynamic list of methods
1747 instead of a static list generated at build time
1748 * fixed PMKSA cache deinitialization not to use freed memory when
1749 removing PMKSA entries
1750 * fixed a memory leak in EAP-TTLS re-authentication
1751 * reject WPA/WPA2 message 3/4 if it does not include any valid
1752 WPA/RSN IE
1753 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
1754 if the driver does not support SIOCSIWAUTH
1755
17562006-01-29 - v0.5.1
1757 * driver_test: added better support for multiple APs and STAs by using
1758 a directory with sockets that include MAC address for each device in
1759 the name (driver_param=test_dir=/tmp/test)
1760 * added support for EAP expanded type (vendor specific EAP methods)
1761 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
1762 option can be changed if needed
1763 * wpa_cli/wpa_gui: skip non-socket files in control directory when
1764 using UNIX domain sockets; this avoids selecting an incorrect
1765 interface (e.g., a PID file could be in this directory, even though
1766 use of this directory for something else than socket files is not
1767 recommended)
1768 * fixed TLS library deinitialization after RSN pre-authentication not
1769 to disable TLS library for normal authentication
1770 * driver_wext: Remove null-termination from SSID length if the driver
1771 used it; some Linux drivers do this and they were causing problems in
1772 wpa_supplicant not finding matching configuration block. This change
1773 would break a case where the SSID actually ends in '\0', but that is
1774 not likely to happen in real use.
1775 * fixed PMKSA cache processing not to trigger deauthentication if the
1776 current PMKSA cache entry is replaced with a valid new entry
1777 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
1778 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
1779 ap_scan=2)
1780
17812005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
1782 * added experimental STAKey handshake implementation for IEEE 802.11e
1783 direct link setup (DLS); note: this is disabled by default in both
1784 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
1785 and stakey=1)
1786 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
1787 decrypt AT_ENCR_DATA attributes correctly
1788 * fixed EAP-AKA to allow resynchronization within the same session
1789 * made code closer to ANSI C89 standard to make it easier to port to
1790 other C libraries and compilers
1791 * started moving operating system or C library specific functions into
1792 wrapper functions defined in os.h and implemented in os_*.c to make
1793 code more portable
1794 * wpa_supplicant can now be built with Microsoft Visual C++
1795 (e.g., with the freely available Toolkit 2003 version or Visual
1796 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
1797 example makefile for nmake
1798 * added support for using Windows registry for command line parameters
1799 (CONFIG_MAIN=main_winsvc) and configuration data
1800 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
1801 contents; this version can be run both as a Windows service and as a
1802 normal application; 'wpasvc.exe app' to start as applicant,
1803 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
1804 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
1805 unregister a service
1806 * made it possible to link ndis_events.exe functionality into
1807 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
1808 * added better support for multiple control interface backends
1809 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
1810 * fixed PC/SC code to use correct length for GSM AUTH command buffer
1811 and to not use pioRecvPci with SCardTransmit() calls; these were not
1812 causing visible problems with pcsc-lite, but Windows Winscard.dll
1813 refused the previously used parameters; this fixes EAP-SIM and
1814 EAP-AKA authentication using SIM/USIM card under Windows
1815 * added new event loop implementation for Windows using
1816 WaitForMultipleObject() instead of select() in order to allow waiting
1817 for non-socket objects; this can be selected with
1818 CONFIG_ELOOP=eloop_win in .config
1819 * added support for selecting l2_packet implementation in .config
1820 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
1821 winpcap, freebsd, none)
1822 * added new l2_packet implementation for WinPcap
1823 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
1824 reduce latency in EAPOL receive processing from about 100 ms to about
1825 3 ms
1826 * added support for EAP-FAST key derivation using other ciphers than
1827 RC4-128-SHA for authentication and AES128-SHA for provisioning
1828 * added support for configuring CA certificate as DER file and as a
1829 configuration blob
1830 * fixed private key configuration as configuration blob and added
1831 support for using PKCS#12 as a blob
1832 * tls_gnutls: added support for using PKCS#12 files; added support for
1833 session resumption
1834 * added support for loading trusted CA certificates from Windows
1835 certificate store: ca_cert="cert_store://<name>", where <name> is
1836 likely CA (Intermediate CA certificates) or ROOT (root certificates)
1837 * added C version of ndis_events.cpp and made it possible to build this
1838 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
1839 easily on cross-compilation builds
1840 * added wpasvc.exe into Windows binary release; this is an alternative
1841 version of wpa_supplicant.exe with configuration backend using
1842 Windows registry and with the entry point designed to run as a
1843 Windows service
1844 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
1845 wpasvc.exe and removed this additional tool from the Windows binary
1846 release since it is not needed anymore
1847 * load winscard.dll functions dynamically when building with MinGW
1848 since MinGW does not yet include winscard library
1849
18502005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
1851 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
1852 and WinPcap to receive frames sent to PAE group address
1853 * disable EAP state machine when IEEE 802.1X authentication is not used
1854 in order to get rid of bogus "EAP failed" messages
1855 * fixed OpenSSL error reporting to go through all pending errors to
1856 avoid confusing reports of old errors being reported at later point
1857 during handshake
1858 * fixed configuration file updating to not write empty variables
1859 (e.g., proto or key_mgmt) that the file parser would not accept
1860 * fixed ADD_NETWORK ctrl_iface command to use the same default values
1861 for variables as empty network definitions read from config file
1862 would get
1863 * fixed EAP state machine to not discard EAP-Failure messages in many
1864 cases (e.g., during TLS handshake)
1865 * fixed a infinite loop in private key reading if the configured file
1866 cannot be parsed successfully
1867 * driver_madwifi: added support for madwifi-ng
1868 * wpa_gui: do not display password/PSK field contents
1869 * wpa_gui: added CA certificate configuration
1870 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
1871 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
1872 the new AP is using different WPA/RSN IE
1873 * use longer timeout for IEEE 802.11 association to avoid problems with
1874 drivers that may take more than five second to associate
1875
18762005-10-27 - v0.4.6
1877 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
1878 RSN IE, but WPA IE would match with wpa_supplicant configuration
1879 * added support for named configuration blobs in order to avoid having
1880 to use file system for external files (e.g., certificates);
1881 variables can be set to "blob://<blob name>" instead of file path to
1882 use a named blob; supported fields: pac_file, client_cert,
1883 private_key
1884 * fixed RSN pre-authentication (it was broken in the clean up of WPA
1885 state machine interface in v0.4.5)
1886 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
1887 sure the driver configures broadcast decryption correctly
1888 * added ca_path (and ca_path2) configuration variables that can be used
1889 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
1890 system-wide trusted CA list
1891 * added support for starting wpa_supplicant without a configuration
1892 file (-C argument must be used to set ctrl_interface parameter for
1893 this case; in addition, -p argument can be used to provide
1894 driver_param; these new arguments can also be used with a
1895 configuration to override the values from the configuration)
1896 * added global control interface that can be optionally used for adding
1897 and removing network interfaces dynamically (-g command line argument
1898 for both wpa_supplicant and wpa_cli) without having to restart
1899 wpa_supplicant process
1900 * wpa_gui:
1901 - try to save configuration whenever something is modified
1902 - added WEP key configuration
1903 - added possibility to edit the current network configuration
1904 * driver_ndis: fixed driver polling not to increase frequency on each
1905 received EAPOL frame due to incorrectly cancelled timeout
1906 * added simple configuration file examples (in examples subdirectory)
1907 * fixed driver_wext.c to filter wireless events based on ifindex to
1908 avoid interfaces receiving events from other interfaces
1909 * delay sending initial EAPOL-Start couple of seconds to speed up
1910 authentication for the most common case of Authenticator starting
1911 EAP authentication immediately after association
1912
19132005-09-25 - v0.4.5
1914 * added a workaround for clearing keys with ndiswrapper to allow
1915 roaming from WPA enabled AP to plaintext one
1916 * added docbook documentation (doc/docbook) that can be used to
1917 generate, e.g., man pages
1918 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
1919 PF_PACKET in order to prepare for network devices that do not use
Hai Shaloma20dcd72022-02-04 13:43:00 -08001920 Ethernet headers (e.g., network stack that includes IEEE 802.11
1921 header in the frames)
Dmitry Shmidt8d520ff2011-05-09 14:06:53 -07001922 * use receipt of EAPOL-Key frame as a lower layer success indication
1923 for EAP state machine to allow recovery from dropped EAP-Success
1924 frame
1925 * cleaned up internal EAPOL frame processing by not including link
1926 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
1927 header is added only when transmitted the frame; this makes it easier
1928 to use wpa_supplicant on link layers that use different header than
1929 Ethernet
1930 * updated EAP-PSK to use draft 9 by default since this can now be
1931 tested with hostapd; removed support for draft 3, including
1932 server_nai configuration option from network blocks
1933 * driver_wired: add PAE address to the multicast address list in order
1934 to be able to receive EAPOL frames with drivers that do not include
1935 these multicast addresses by default
1936 * driver_wext: add support for WE-19
1937 * added support for multiple configuration backends (CONFIG_BACKEND
1938 option); currently, only 'file' is supported (i.e., the format used
1939 in wpa_supplicant.conf)
1940 * added support for updating configuration ('wpa_cli save_config');
1941 this is disabled by default and can be enabled with global
1942 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
1943 and wpa_gui to store the configuration changes in a permanent store
1944 * added GET_NETWORK ctrl_iface command
1945 (e.g., 'wpa_cli get_network 0 ssid')
1946
19472005-08-21 - v0.4.4
1948 * replaced OpenSSL patch for EAP-FAST support
1949 (openssl-tls-extensions.patch) with a more generic and correct
1950 patch (the new patch is not compatible with the previous one, so the
1951 OpenSSL library will need to be patched with the new patch in order
1952 to be able to build wpa_supplicant with EAP-FAST support)
1953 * added support for using Windows certificate store (through CryptoAPI)
1954 for client certificate and private key operations (EAP-TLS)
1955 (see wpa_supplicant.conf for more information on how to configure
1956 this with private_key)
1957 * ported wpa_gui to Windows
1958 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
1959 built with the open source version of the Qt4 for Windows
1960 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
1961 with drivers that do not support WPA
1962 * ndis_events: fixed Windows 2000 support
1963 * added support for enabling/disabling networks from the list of all
1964 configured networks ('wpa_cli enable_network <network id>' and
1965 'wpa_cli disable_network <network id>')
1966 * added support for adding and removing network from the current
1967 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
1968 <network id>'); added networks are disabled by default and they can
1969 be enabled with enable_network command once the configuration is done
1970 for the new network; note: configuration file is not yet updated, so
1971 these new networks are lost when wpa_supplicant is restarted
1972 * added support for setting network configuration parameters through
1973 the control interface, for example:
1974 wpa_cli set_network 0 ssid "\"my network\""
1975 * fixed parsing of strings that include both " and # within double
1976 quoted area (e.g., "start"#end")
1977 * added EAP workaround for PEAP session resumption: allow outer,
1978 i.e., not tunneled, EAP-Success to terminate session since; this can
1979 be disabled with eap_workaround=0
1980 (this was allowed for PEAPv1 before, but now it is also allowed for
1981 PEAPv0 since at least one RADIUS authentication server seems to be
1982 doing this for PEAPv0, too)
1983 * wpa_gui: added preliminary support for adding new networks to the
1984 wpa_supplicant configuration (double click on the scan results to
1985 open network configuration)
1986
19872005-06-26 - v0.4.3
1988 * removed interface for external EAPOL/EAP supplicant (e.g.,
1989 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
1990 anymore and is unlikely to be used by anyone
1991 * driver_ndis: fixed WinPcap 3.0 support
1992 * fixed build with CONFIG_DNET_PCAP=y on Linux
1993 * l2_packet: moved different implementations into separate files
1994 (l2_packet_*.c)
1995
19962005-06-12 - v0.4.2
1997 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
1998 (note: ipw2100-1.1.0 is likely to require an update to work with
1999 this)
2000 * added support for using ap_scan=2 mode with multiple network blocks;
2001 wpa_supplicant will go through the networks one by one until the
2002 driver reports a successful association; this uses the same order for
2003 networks as scan_ssid=1 scans, i.e., the priority field is ignored
2004 and the network block order in the file is used instead
2005 * fixed a potential issue in RSN pre-authentication ending up using
2006 freed memory if pre-authentication times out
2007 * added support for matching alternative subject name extensions of the
2008 authentication server certificate; new configuration variables
2009 altsubject_match and altsubject_match2
2010 * driver_ndis: added support for IEEE 802.1X authentication with wired
2011 NDIS drivers
2012 * added support for querying private key password (EAP-TLS) through the
2013 control interface (wpa_cli/wpa_gui) if one is not included in the
2014 configuration file
2015 * driver_broadcom: fixed couple of memory leaks in scan result
2016 processing
2017 * EAP-PAX is now registered as EAP type 46
2018 * fixed EAP-PAX MAC calculation
2019 * fixed EAP-PAX CK and ICK key derivation
2020 * added support for using password with EAP-PAX (as an alternative to
2021 entering key with eappsk); SHA-1 hash of the password will be used as
2022 the key in this case
2023 * added support for arbitrary driver interface parameters through the
2024 configuration file with a new driver_param field; this adds a new
2025 driver_ops function set_param()
2026 * added possibility to override l2_packet module with driver interface
2027 API (new send_eapol handler); this can be used to implement driver
2028 specific TX/RX functions for EAPOL frames
2029 * fixed ctrl_interface_group processing for the case where gid is
2030 entered as a number, not group name
2031 * driver_test: added support for testing hostapd with wpa_supplicant
2032 by using test driver interface without any kernel drivers or network
2033 cards
2034
20352005-05-22 - v0.4.1
2036 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
2037 packets to be encrypted; this was apparently broken by the changed
2038 ioctl order in v0.4.0
2039 * driver_madwifi: added preliminary support for compiling against 'BSD'
2040 branch of madwifi CVS tree
2041 * added support for EAP-MSCHAPv2 password retries within the same EAP
2042 authentication session
2043 * added support for password changes with EAP-MSCHAPv2 (used when the
2044 password has expired)
2045 * added support for reading additional certificates from PKCS#12 files
2046 and adding them to the certificate chain
2047 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
2048 were used
2049 * fixed a possible double free in EAP-TTLS fast-reauthentication when
2050 identity or password is entered through control interface
2051 * display EAP Notification messages to user through control interface
2052 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
2053 * added GUI version of wpa_cli, wpa_gui; this is not build
2054 automatically with 'make'; use 'make wpa_gui' to build (this requires
2055 Qt development tools)
2056 * added 'disconnect' command to control interface for setting
2057 wpa_supplicant in state where it will not associate before
2058 'reassociate' command has been used
2059 * added support for selecting a network from the list of all configured
2060 networks ('wpa_cli select_network <network id>'; this disabled all
2061 other networks; to re-enable, 'wpa_cli select_network any')
2062 * added support for getting scan results through control interface
2063 * added EAP workaround for PEAPv1 session resumption: allow outer,
2064 i.e., not tunneled, EAP-Success to terminate session since; this can
2065 be disabled with eap_workaround=0
2066
20672005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
2068 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
2069 used to reduce the size of the wpa_supplicant considerably if
2070 debugging code is not needed
2071 * fixed EAPOL-Key validation to drop packets with invalid Key Data
2072 Length; such frames could have crashed wpa_supplicant due to buffer
2073 overflow
2074 * added support for wired authentication (IEEE 802.1X on wired
2075 Ethernet); driver interface 'wired'
2076 * obsoleted set_wpa() handler in the driver interface API (it can be
2077 replaced by moving enable/disable functionality into init()/deinit())
2078 (calls to set_wpa() are still present for backwards compatibility,
2079 but they may be removed in the future)
2080 * driver_madwifi: fixed association in plaintext mode
2081 * modified the EAP workaround that accepts EAP-Success with incorrect
2082 Identifier to be even less strict about verification in order to
2083 interoperate with some authentication servers
2084 * added support for sending TLS alerts
2085 * added support for 'any' SSID wildcard; if ssid is not configured or
2086 is set to an empty string, any SSID will be accepted for non-WPA AP
2087 * added support for asking PIN (for SIM) from frontends (e.g.,
2088 wpa_cli); if a PIN is needed, but not included in the configuration
2089 file, a control interface request is sent and EAP processing is
2090 delayed until the PIN is available
2091 * added support for using external devices (e.g., a smartcard) for
2092 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
2093 new wpa_supplicant.conf variables:
2094 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
2095 - network: engine, engine_id, key_id
2096 * added experimental support for EAP-PAX
2097 * added monitor mode for wpa_cli (-a<path to a program to run>) that
2098 allows external commands (e.g., shell scripts) to be run based on
2099 wpa_supplicant events, e.g., when authentication has been completed
2100 and data connection is ready; other related wpa_cli arguments:
2101 -B (run in background), -P (write PID file); wpa_supplicant has a new
2102 command line argument (-W) that can be used to make it wait until a
2103 control interface command is received in order to avoid missing
2104 events
2105 * added support for opportunistic WPA2 PMKSA key caching (disabled by
2106 default, can be enabled with proactive_key_caching=1)
2107 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
2108 Authenticator rejects PMKSA caching attempt and the driver is not
2109 using assoc_info events
2110 * added -P<pid file> argument for wpa_supplicant to write the current
2111 process id into a file
2112
21132005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
2114 * added new phase1 option parameter, include_tls_length=1, to force
2115 wpa_supplicant to add TLS Message Length field to all TLS messages
2116 even if the packet is not fragmented; this may be needed with some
2117 authentication servers
2118 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
2119 using drivers that take care of AP selection (e.g., when using
2120 ap_scan=2)
2121 * fixed reprocessing of pending request after ctrl_iface requests for
2122 identity/password/otp
2123 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
2124 EAP-PEAP and EAP-TTLS
2125 * all drivers using driver_wext: set interface up and select Managed
2126 mode when starting wpa_supplicant; set interface down when exiting
2127 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
2128 ipw2100 and ipw2200; please note that this also changed the
2129 configuration variable in .config to CONFIG_DRIVER_IPW
2130
21312005-01-24 - v0.3.6
2132 * fixed a busy loop introduced in v0.3.5 for scan result processing
2133 when no matching AP is found
2134
21352005-01-23 - v0.3.5
2136 * added a workaround for an interoperability issue with a Cisco AP
2137 when using WPA2-PSK
2138 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
2139 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
2140 retransmission of dropped frames)
2141 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
2142 (e.g., segfault when processing EAPOL-Key frames)
2143 * fixed EAP workaround and fast reauthentication configuration for
2144 RSN pre-authentication; previously these were disabled and
2145 pre-authentication would fail if the used authentication server
2146 requires EAP workarounds
2147 * added support for blacklisting APs that fail or timeout
2148 authentication in ap_scan=1 mode so that all APs are tried in cases
2149 where the ones with strongest signal level are failing authentication
2150 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
2151 authentication attempt
2152 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
2153 in the previous authentication (previously, only Phase 1 success was
2154 verified)
2155
21562005-01-09 - v0.3.4
2157 * added preliminary support for IBSS (ad-hoc) mode configuration
2158 (mode=1 in network block); this included a new key_mgmt mode
2159 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
2160 key management; see wpa_supplicant.conf for more details and an
2161 example on how to configure this (note: this is currently implemented
2162 only for driver_hostapd.c, but the changes should be trivial to add
2163 in associate() handler for other drivers, too (assuming the driver
2164 supports WPA-None)
2165 * added preliminary port for native Windows (i.e., no cygwin) using
2166 mingw
2167
21682005-01-02 - v0.3.3
2169 * added optional support for GNU Readline and History Libraries for
2170 wpa_cli (CONFIG_READLINE)
2171 * cleaned up EAP state machine <-> method interface and number of
2172 small problems with error case processing not terminating on
2173 EAP-Failure but waiting for timeout
2174 * added couple of workarounds for interoperability issues with a
2175 Cisco AP when using WPA2
2176 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
2177 Note: This requires a patch for openssl to add support for TLS
2178 extensions and number of workarounds for operations without
2179 certificates. Proof of concept type of experimental patch is
2180 included in openssl-tls-extensions.patch.
2181
21822004-12-19 - v0.3.2
2183 * fixed private key loading for cases where passphrase is not set
2184 * fixed Windows/cygwin L2 packet handler freeing; previous version
2185 could cause a segfault when RSN pre-authentication was completed
2186 * added support for PMKSA caching with drivers that generate RSN IEs
2187 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
2188 but similar code can be easily added to driver_ndiswrapper.c once
2189 ndiswrapper gets full support for RSN PMKSA caching
2190 * improved recovery from PMKID mismatches by requesting full EAP
2191 authentication in case of failed PMKSA caching attempt
2192 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
2193 (this requires that ndis_events is ran while wpa_supplicant is
2194 running)
2195 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
2196 * added support for driver interfaces to replace the interface name
2197 based on driver/OS specific mapping, e.g., in case of driver_ndis,
2198 this allows the beginning of the adapter description to be used as
2199 the interface name
2200 * added support for CR+LF (Windows-style) line ends in configuration
2201 file
2202 * driver_ndis: enable radio before starting scanning, disable radio
2203 when exiting
2204 * modified association event handler to set portEnabled = FALSE before
2205 clearing port Valid in order to reset EAP state machine and avoid
2206 problems with new authentication getting ignored because of state
2207 machines ending up in AUTHENTICATED/SUCCESS state based on old
2208 information
2209 * added support for driver events to add PMKID candidates in order to
2210 allow drivers to give priority to most likely roaming candidates
2211 * driver_hostap: moved PrivacyInvoked configuration to associate()
2212 function so that this will not be set for plaintext connections
2213 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
2214 interface can distinguish plaintext and IEEE 802.1X (no WPA)
2215 authentication
2216 * fixed static WEP key configuration to use broadcast/default type for
2217 all keys (previously, the default TX key was configured as pairwise/
2218 unicast key)
2219 * driver_ndis: added legacy WPA capability detection for non-WPA2
2220 drivers
2221 * added support for setting static WEP keys for IEEE 802.1X without
2222 dynamic WEP keying (eapol_flags=0)
2223
22242004-12-12 - v0.3.1
2225 * added support for reading PKCS#12 (PFX) files (as a replacement for
2226 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
2227 * fixed compilation with CONFIG_PCSC=y
2228 * added new ap_scan mode, ap_scan=2, for drivers that take care of
2229 association, but need to be configured with security policy and SSID,
2230 e.g., ndiswrapper and NDIS driver; this mode should allow such
2231 drivers to work with hidden SSIDs and optimized roaming; when
2232 ap_scan=2 is used, only the first network block in the configuration
2233 file is used and this configuration should have explicit security
2234 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
2235 group, proto variables
2236 * added experimental port of wpa_supplicant for Windows
2237 - driver_ndis.c driver interface (NDIS OIDs)
2238 - currently, this requires cygwin and WinPcap
2239 - small utility, win_if_list, can be used to get interface name
2240 * control interface can now be removed at build time; add
2241 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
2242 * optional Xsupplicant interface can now be removed at build time;
2243 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
2244 * added auth_alg to driver interface associate() parameters to make it
2245 easier for drivers to configure authentication algorithm as part of
2246 the association
2247
22482004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
2249 * driver_broadcom: added new driver interface for Broadcom wl.o driver
2250 (a generic driver for Broadcom IEEE 802.11a/g cards)
2251 * wpa_cli: fixed parsing of -p <path> command line argument
2252 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
2253 ACK, not tunneled EAP-Success (of which only the first byte was
2254 actually send due to a bug in previous code); this seems to
2255 interoperate with most RADIUS servers that implements PEAPv1
2256 * PEAPv1: added support for terminating PEAP authentication on tunneled
2257 EAP-Success message; this can be configured by adding
2258 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
2259 (some RADIUS servers require this whereas others require a tunneled
2260 reply
2261 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
2262 the old label for key derivation; previously, the default was 1,
2263 but it looks like most existing PEAPv1 implementations use the old
2264 label which is thus more suitable default option
2265 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
2266 * fixed parsing of wep_tx_keyidx
2267 * added support for configuring list of allowed Phase 2 EAP types
2268 (for both EAP-PEAP and EAP-TTLS) instead of only one type
2269 * added support for configuring IEEE 802.11 authentication algorithm
2270 (auth_alg; mainly for using Shared Key authentication with static
2271 WEP keys)
2272 * added support for EAP-AKA (with UMTS SIM)
2273 * fixed couple of errors in PCSC handling that could have caused
2274 random-looking errors for EAP-SIM
2275 * added support for EAP-SIM pseudonyms and fast re-authentication
2276 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
2277 session resumption)
Hai Shalom60840252021-02-19 19:02:11 -08002278 * added support for EAP-SIM with two challenges
Dmitry Shmidt8d520ff2011-05-09 14:06:53 -07002279 (phase1="sim_min_num_chal=3" can be used to require three challenges)
2280 * added support for configuring DH/DSA parameters for an ephemeral DH
2281 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
2282 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
2283 and optional DH key exchange to achieve forward secracy with RSA keys
2284 * added support for matching subject of the authentication server
2285 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
2286 configuration variables subject_match and subject_match2
2287 * changed SSID configuration in driver_wext.c (used by many driver
2288 interfaces) to use ssid_len+1 as the length for SSID since some Linux
2289 drivers expect this
2290 * fixed couple of unaligned reads in scan result parsing to fix WPA
2291 connection on some platforms (e.g., ARM)
2292 * added driver interface for Intel ipw2100 driver
2293 * added support for LEAP with WPA
2294 * added support for larger scan results report (old limit was 4 kB of
2295 data, i.e., about 35 or so APs) when using Linux wireless extensions
2296 v17 or newer
2297 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
2298 only if there is a PMKSA cache entry for the current AP
2299 * fixed error handling for case where reading of scan results fails:
2300 must schedule a new scan or wpa_supplicant will remain waiting
2301 forever
2302 * changed debug output to remove shared password/key material by
2303 default; all key information can be included with -K command line
2304 argument to match the previous behavior
2305 * added support for timestamping debug log messages (disabled by
2306 default, can be enabled with -t command line argument)
2307 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
2308 if keys are not configured to be used; this fixes IEEE 802.1X mode
2309 with drivers that use this information to configure whether Privacy
2310 bit can be in Beacon frames (e.g., ndiswrapper)
2311 * avoid clearing driver keys if no keys have been configured since last
2312 key clear request; this seems to improve reliability of group key
2313 handshake for ndiswrapper & NDIS driver which seems to be suffering
2314 of some kind of timing issue when the keys are cleared again after
2315 association
2316 * changed driver interface API:
2317 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
2318 version is being used (now, this is set to 2; previously, it was
2319 not defined)
2320 - pass pointer to private data structure to all calls
2321 - the new API is not backwards compatible; all in-tree driver
2322 interfaces has been converted to the new API
2323 * added support for controlling multiple interfaces (radios) per
2324 wpa_supplicant process; each interface needs to be listed on the
2325 command line (-c, -i, -D arguments) with -N as a separator
2326 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
2327 * added a workaround for EAP servers that incorrectly use same Id for
2328 sequential EAP packets
2329 * changed libpcap/libdnet configuration to use .config variable,
2330 CONFIG_DNET_PCAP, instead of requiring Makefile modification
2331 * improved downgrade attack detection in IE verification of msg 3/4:
2332 verify both WPA and RSN IEs, if present, not only the selected one;
2333 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
2334 Probe Response frame, and RSN is enabled in wpa_supplicant
2335 configuration
2336 * fixed WPA msg 3/4 processing to allow Key Data field contain other
2337 IEs than just one WPA IE
2338 * added support for FreeBSD and driver interface for the BSD net80211
2339 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
2340 required kernel mods have not yet been committed
2341 * made EAP workarounds configurable; enabled by default, can be
2342 disabled with network block option eap_workaround=0
2343
23442004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
2345 * resolved couple of interoperability issues with EAP-PEAPv1 and
2346 Phase 2 (inner EAP) fragment reassembly
2347 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
2348 AP is using non-zero key index for the unicast key and key index zero
2349 for the broadcast key
2350 * driver_hostap: fixed IEEE 802.1X WEP key updates and
2351 re-authentication by allowing unencrypted EAPOL frames when not using
2352 WPA
2353 * added a new driver interface, 'wext', which uses only standard,
2354 driver independent functionality in Linux wireless extensions;
2355 currently, this can be used only for non-WPA IEEE 802.1X mode, but
2356 eventually, this is to be extended to support full WPA/WPA2 once
2357 Linux wireless extensions get support for this
2358 * added support for mode in which the driver is responsible for AP
2359 scanning and selection; this is disabled by default and can be
2360 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
2361 this mode can be used, e.g., with generic 'wext' driver interface to
2362 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
2363 supporting wireless extensions.
2364 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
2365 operation with an AP that does not include SSID in the Beacon frames)
2366 * added support for new EAP authentication methods:
2367 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
2368 * added support for asking one-time-passwords from frontends (e.g.,
2369 wpa_cli); this 'otp' command works otherwise like 'password' command,
2370 but the password is used only once and the frontend will be asked for
2371 a new password whenever a request from authenticator requires a
2372 password; this can be used with both EAP-OTP and EAP-GTC
2373 * changed wpa_cli to automatically re-establish connection so that it
2374 does not need to be re-started when wpa_supplicant is terminated and
2375 started again
2376 * improved user data (identity/password/otp) requests through
2377 frontends: process pending EAPOL packets after getting new
2378 information so that full authentication does not need to be
2379 restarted; in addition, send pending requests again whenever a new
2380 frontend is attached
2381 * changed control frontends to use a new directory for socket files to
2382 make it easier for wpa_cli to automatically select between interfaces
2383 and to provide access control for the control interface;
2384 wpa_supplicant.conf: ctrl_interface is now a path
2385 (/var/run/wpa_supplicant is the recommended path) and
2386 ctrl_interface_group can be used to select which group gets access to
2387 the control interface;
2388 wpa_cli: by default, try to connect to the first interface available
Hai Shalom60840252021-02-19 19:02:11 -08002389 in /var/run/wpa_supplicant; this path can be overridden with -p option
Dmitry Shmidt8d520ff2011-05-09 14:06:53 -07002390 and an interface can be selected with -i option (i.e., in most common
2391 cases, wpa_cli does not need to get any arguments)
2392 * added support for LEAP
2393 * added driver interface for Linux ndiswrapper
2394 * added priority option for network blocks in the configuration file;
2395 this allows networks to be grouped based on priority (the scan
2396 results are searched for matches with network blocks in this order)
2397
23982004-06-20 - v0.2.3
2399 * sort scan results to improve AP selection
2400 * fixed control interface socket removal for some error cases
2401 * improved scan requesting and authentication timeout
2402 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
2403 TLS processing
2404 * PEAP version can now be forced with phase1="peapver=<ver>"
2405 (mostly for testing; by default, the highest version supported by
2406 both the Supplicant and Authentication Server is selected
2407 automatically)
2408 * added support for madwifi driver (Atheros ar521x)
2409 * added a workaround for cases where AP sets Install Tx/Rx bit for
2410 WPA Group Key messages when pairwise keys are used (without this,
2411 the Group Key would be used for Tx and the AP would drop frames
2412 from the station)
2413 * added GSM SIM/USIM interface for GSM authentication algorithm for
2414 EAP-SIM; this requires pcsc-lite
2415 * added support for ATMEL AT76C5XXx driver
2416 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
2417 does not include key data in the EAPOL-Key frame (i.e., part of
2418 EAP keying material is used as data encryption key)
2419 * added support for using plaintext and static WEP networks
2420 (key_mgmt=NONE)
2421
24222004-05-31 - v0.2.2
2423 * added support for new EAP authentication methods:
2424 EAP-TTLS/EAP-MD5-Challenge
2425 EAP-TTLS/EAP-GTC
2426 EAP-TTLS/EAP-MSCHAPv2
2427 EAP-TTLS/EAP-TLS
2428 EAP-TTLS/MSCHAPv2
2429 EAP-TTLS/MSCHAP
2430 EAP-TTLS/PAP
2431 EAP-TTLS/CHAP
2432 EAP-PEAP/TLS
2433 EAP-PEAP/GTC
2434 EAP-PEAP/MD5-Challenge
2435 EAP-GTC
2436 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
2437 * added support for anonymous identity (to be used when identity is
2438 sent in plaintext; real identity will be used within TLS protected
2439 tunnel (e.g., with EAP-TTLS)
2440 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
2441 * added support for requesting identity and password information using
2442 control interface; in other words, the password for EAP-PEAP or
2443 EAP-TTLS does not need to be included in the configuration file since
2444 a frontand (e.g., wpa_cli) can ask it from the user
2445 * improved RSN pre-authentication to use a candidate list and process
2446 all candidates from each scan; not only one per scan
2447 * fixed RSN IE and WPA IE capabilities field parsing
2448 * ignore Tx bit in GTK IE when Pairwise keys are used
2449 * avoid making new scan requests during IEEE 802.1X negotiation
2450 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
2451 with TLS support (this replaces the included implementation with
2452 library code to save about 8 kB since the library code is needed
2453 anyway for TLS)
2454 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
2455 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
2456
24572004-05-06 - v0.2.1
2458 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
2459 Supplicant
2460 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
2461 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
2462 - EAP-MD5 (cannot be used with WPA-RADIUS)
2463 [draft-ietf-eap-rfc2284bis-09.txt]
2464 - EAP-TLS [RFC 2716]
2465 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
2466 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
2467 [draft-kamath-pppext-eap-mschapv2-00.txt]
2468 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
2469 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
2470 - new configuration file options: eap, identity, password, ca_cert,
2471 client_cert, privatekey, private_key_passwd
2472 - Xsupplicant is not required anymore, but it can be used by
2473 disabling the internal IEEE 802.1X Supplicant with -e command line
2474 option
2475 - this code is not included in the default build; Makefile need to
2476 be edited for this (uncomment lines for selected functionality)
2477 - EAP-TLS and EAP-PEAP require openssl libraries
2478 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
2479 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
2480 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
2481 EAPOL-Key frames instead of WPA key handshakes)
2482 * added support for IEEE 802.11i/RSN (WPA2)
2483 - improved PTK Key Handshake
2484 - PMKSA caching, pre-authentication
2485 * fixed wpa_supplicant to ignore possible extra data after WPA
2486 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
2487 TPTK' error from message 3 of 4-Way Handshake in case the AP
2488 includes extra data after the EAPOL-Key)
2489 * added interface for external programs (frontends) to control
2490 wpa_supplicant
2491 - CLI example (wpa_cli) with interactive mode and command line
2492 mode
2493 - replaced SIGUSR1 status/statistics with the new control interface
