548            HT/VHT/specific TX rate support)
549          * add INTERWORKING_ADD_NETWORK ctrl_iface command; this can be used to

978          * EAP-TTLS: fixed peer challenge generation for MSCHAPv2
979          * SME: do not use reassociation after explicit disconnection request
980            (local or a notification from an AP)
981          * added support for sending debug info to Linux tracing (-T on command
982            line)

1037            - tls_disable_session_ticket=1
1038            - automatically disable TLS Session Ticket extension by default when
1039              using EAP-TLS/PEAP/TTLS (i.e., only use it with EAP-FAST)
1040          * changed VENDOR-TEST EAP method to use proper private enterprise number

1050              and codecs
1051          * optimized scan result use for network selection
1052            - use the internal BSS table instead of raw scan results
1053            - allow unnecessary scans to be skipped if fresh information is
1054              available (e.g., after GAS/ANQP round for Interworking)
1055          * added support for 256-bit AES with internal TLS implementation
1056          * allow peer to propose channel in P2P invitation process for a
1057            persistent group

1067            for the same key
1068          * use deauthentication instead of disassociation for all disconnection
1069            operations; this removes the now unused disassociate() wpa_driver_ops
1070            callback
1071          * optimized PSK generation on P2P GO by caching results to avoid
1072            multiple PBKDF2 operations

10832012-05-10 - v1.0
1084          * bsd: Add support for setting HT values in IFM_MMASK.
1085          * Delay STA entry removal until Deauth/Disassoc TX status in AP mode.
1086            This allows the driver to use PS buffering of Deauthentication and
1087            Disassociation frames when the STA is in power save sleep. Only
1088            available with drivers that provide TX status events for Deauth/
1089            Disassoc frames (nl80211).
1090          * Drop oldest unknown BSS table entries first. This makes it less
1091            likely to hit connection issues in environments with huge number
1092            of visible APs.
1093          * Add systemd support.

1098            config parameter ieee80211n.
1099          * Allow AP mode to disconnect STAs based on low ACK condition (when
1100            the data connection is not working properly, e.g., due to the STA
1101            going outside the range of the AP). Disabled by default, enable by
1102            config option disassoc_low_ack.
1103          * nl80211:
1104            - Support GTK rekey offload.
1105            - Support PMKSA candidate events. This adds support for RSN
1106              pre-authentication with nl80211 interface and drivers that handle
1107              roaming internally.
1108          * dbus:
1109            - Add a DBus signal for EAP SM requests, emitted on the Interface
1110              object.
1111            - Export max scan ssids supported by the driver as MaxScanSSID.
1112            - Add signal Certification for information about server certification.
1113            - Add BSSExpireAge and BSSExpireCount interface properties and
1114              support set/get, which allows for setting BSS cache expiration age
1115              and expiration scan count.
1116            - Add ConfigFile to AddInterface properties.
1117            - Add Interface.Country property and support to get/set the value.
1118            - Add DBus property CurrentAuthMode.
1119            - P2P DBus API added.
1120            - Emit property changed events (for property BSSs) when adding/
1121              removing BSSs.
1122            - Treat '' in SSIDs of Interface.Scan as a request for broadcast
1123              scan, instead of ignoring it.
1124            - Add DBus getter/setter for FastReauth.
1125            - Raise PropertiesChanged on org.freedesktop.DBus.Properties.
1126          * wpa_cli:
1127            - Send AP-STA-DISCONNECTED event when an AP disconnects a station
1128              due to inactivity.
1129            - Make second argument to set command optional. This can be used to
1130              indicate a zero length value.
1131            - Add signal_poll command.
1132            - Add bss_expire_age and bss_expire_count commands to set/get BSS
1133              cache expiration age and expiration scan count.
1134            - Add ability to set scan interval (the time in seconds wpa_s waits
1135              before requesting a new scan after failing to find a suitable
1136              network in scan results) using scan_interval command.
1137            - Add event CTRL-EVENT-ASSOC-REJECT for association rejected.
1138            - Add command get version, that returns wpa_supplicant version string.
1139            - Add command sta_autoconnect for disabling automatic reconnection
1140              on receiving disconnection event.
1141            - Setting bssid parameter to an empty string "" or any can now be
1142              used to clear the bssid_set flag in a network block, i.e., to remove
1143              bssid filtering.
1144            - Add tdls_testing command to add a special testing feature for
1145              changing TDLS behavior. Build param CONFIG_TDLS_TESTING must be
1146              enabled as well.
1147            - For interworking, add wpa_cli commands interworking_select,
1148              interworking_connect, anqp_get, fetch_anqp, and stop_fetch_anqp.
1149            - Many P2P commands were added. See README-P2P.
1150            - Many WPS/WPS ER commands - see WPS/WPS ER sections for details.
1151            - Allow set command to change global config parameters.
1152            - Add log_level command, which can be used to display the current
1153              debugging level and to change the log level during run time.
1154            - Add note command, which can be used to insert notes to the debug
1155              log.
1156            - Add internal line edit implementation. CONFIG_WPA_CLI_EDIT=y
1157              can now be used to build wpa_cli with internal implementation of
1158              line editing and history support. This can be used as a replacement
1159              for CONFIG_READLINE=y.
1160          * AP mode: Add max_num_sta config option, which can be used to limit
1161            the number of stations allowed to connect to the AP.
1162          * Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad
1163            config file.
1164          * wext: Increase scan timeout from 5 to 10 seconds.
1165          * Add blacklist command, allowing an external program to
1166            manage the BSS blacklist and display its current contents.
1167          * WPS:
1168            - Add wpa_cli wps_pin get command for generating random PINs. This can
1169              be used in a UI to generate a PIN without starting WPS (or P2P)
1170              operation.
1171            - Set RF bands based on driver capabilities, instead of hardcoding
1172              them.
1173            - Add mechanism for indicating non-standard WPS errors.
1174            - Add CONFIG_WPS_REG_DISABLE_OPEN=y option to disable open networks
1175              by default.
1176            - Add wps_ap_pin cli command for wpa_supplicant AP mode.
1177            - Add wps_check_pin cli command for processing PIN from user input.
1178              UIs can use this command to process a PIN entered by a user and to
1179              validate the checksum digit (if present).
1180            - Cancel WPS operation on PBC session overlap detection.
1181            - New wps_cancel command in wpa_cli will cancel a pending WPS
1182              operation.
1183            - wpa_cli action: Add WPS_EVENT_SUCCESS and WPS_EVENT_FAIL handlers.
1184            - Trigger WPS config update on Manufacturer, Model Name, Model
1185              Number, and Serial Number changes.
1186            - Fragment size is now configurable for EAP-WSC peer. Use
1187              wpa_cli set wps_fragment_size <val>.
1188            - Disable AP PIN after 10 consecutive failures. Slow down attacks on
1189              failures up to 10.
1190            - Allow AP to start in Enrollee mode without AP PIN for probing, to
1191              be compatible with Windows 7.
1192            - Add Config Error into WPS-FAIL events to provide more info to the
1193              user on how to resolve the issue.
1194            - Label and Display config methods are not allowed to be enabled
1195              at the same time, since it is unclear which PIN to use if both
1196              methods are advertised.
1197            - When controlling multiple interfaces:
1198               - apply WPS commands to all interfaces configured to use WPS
1199               - apply WPS config changes to all interfaces that use WPS
1200               - when an attack is detected on any interface, disable AP PIN on
1201                 all interfaces
1202          * WPS ER:
1203            - Add special AP Setup Locked mode to allow read only ER.
1204              ap_setup_locked=2 can now be used to enable a special mode where
1205              WPS ER can learn the current AP settings, but cannot change them.
1206            - Show SetSelectedRegistrar events as ctrl_iface events
1207            - Add wps_er_set_config to enroll a network based on a local
1208              network configuration block instead of having to (re-)learn the
1209              current AP settings with wps_er_learn.
1210            - Allow AP filtering based on IP address, add ctrl_iface event for
1211              learned AP settings, add wps_er_config command to configure an AP.
1212          * WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2)
1213            - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool
1214              for testing protocol extensibility.
1215            - Add build option CONFIG_WPS_STRICT to allow disabling of WPS
1216              workarounds.
1217            - Add support for AuthorizedMACs attribute.
1218          * TDLS:
1219            - Propagate TDLS related nl80211 capability flags from kernel and
1220              add them as driver capability flags. If the driver doesn't support
1221              capabilities, assume TDLS is supported internally. When TDLS is
1222              explicitly not supported, disable all user facing TDLS operations.
1223            - Allow TDLS to be disabled at runtime (mostly for testing).
1224              Use set tdls_disabled.
1225            - Honor AP TDLS settings that prohibit/allow TDLS.
1226            - Add a special testing feature for changing TDLS behavior. Use
1227              CONFIG_TDLS_TESTING build param to enable. Configure at runtime
1228              with tdls_testing cli command.
1229            - Add support for TDLS 802.11z.
1230          * wlantest: Add a tool wlantest for IEEE802.11 protocol testing.
1231            wlantest can be used to capture frames from a monitor interface
1232            for realtime capturing or from pcap files for offline analysis.
1233          * Interworking: Support added for 802.11u. Enable in .config with
1234            CONFIG_INTERWORKING. See wpa_supplicant.conf for config parameters
1235            for interworking. wpa_cli commands added to support this are
1236            interworking_select, interworking_connect, anqp_get, fetch_anqp,
1237            and stop_fetch_anqp.
1238          * Android: Add build and runtime support for Android wpa_supplicant.
1239          * bgscan learn: Add new bgscan that learns BSS information based on
1240            previous scans, and uses that information to dynamically generate
1241            the list of channels for background scans.
1242          * Add a new debug message level for excessive information. Use
1243            -ddd to enable.
1244          * TLS: Add support for tls_disable_time_checks=1 in client mode.
1245          * Internal TLS:
1246            - Add support for TLS v1.1 (RFC 4346). Enable with build parameter
1247              CONFIG_TLSV11.
1248            - Add domainComponent parser for X.509 names.
1249          * Linux: Add RFKill support by adding an interface state "disabled".
1250          * Reorder some IEs to get closer to IEEE 802.11 standard. Move
1251            WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames.
1252            Move HT IEs to be later in (Re)Assoc Resp.
1253          * Solaris: Add support for wired 802.1X client.
1254          * Wi-Fi Direct support. See README-P2P for more information.
1255          * Many bugfixes.
1256
12572010-04-18 - v0.7.2
1258          * nl80211: fixed number of issues with roaming
1259          * avoid unnecessary roaming if multiple APs with similar signal
1260            strength are present in scan results
1261          * add TLS client events and server probing to ease design of
1262            automatic detection of EAP parameters
1263          * add option for server certificate matching (SHA256 hash of the
1264            certificate) instead of trusted CA certificate configuration
1265          * bsd: Cleaned up driver wrapper and added various low-level
1266            configuration options
1267          * wpa_gui-qt4: do not show too frequent WPS AP available events as
1268            tray messages
1269          * TNC: fixed issues with fragmentation
1270          * EAP-TNC: add Flags field into fragment acknowledgement (needed to
1271            interoperate with other implementations; may potentially breaks
1272            compatibility with older wpa_supplicant/hostapd versions)
1273          * wpa_cli: added option for using a separate process to receive event
1274            messages to reduce latency in showing these
1275            (CFLAGS += -DCONFIG_WPA_CLI_FORK=y in .config to enable this)
1276          * maximum BSS table size can now be configured (bss_max_count)
1277          * BSSes to be included in the BSS table can be filtered based on
1278            configured SSIDs to save memory (filter_ssids)
1279          * fix number of issues with IEEE 802.11r/FT; this version is not
1280            backwards compatible with old versions
1281          * nl80211: add support for IEEE 802.11r/FT protocol (both over-the-air
1282            and over-the-DS)
1283          * add freq_list network configuration parameter to allow the AP
1284            selection to filter out entries based on the operating channel
1285          * add signal strength change events for bgscan; this allows more
1286            dynamic changes to background scanning interval based on changes in
1287            the signal strength with the current AP; this improves roaming within
1288            ESS quite a bit, e.g., with bgscan="simple:30:-45:300" in the network
1289            configuration block to request background scans less frequently when
1290            signal strength remains good and to automatically trigger background
1291            scans whenever signal strength drops noticeably
1292            (this is currently only available with nl80211)
1293          * add BSSID and reason code (if available) to disconnect event messages
1294          * wpa_gui-qt4: more complete support for translating the GUI with
1295            linguist and add German translation
1296          * fix DH padding with internal crypto code (mainly, for WPS)
1297          * do not trigger initial scan automatically anymore if there are no
1298            enabled networks
1299
13002010-01-16 - v0.7.1
1301          * cleaned up driver wrapper API (struct wpa_driver_ops); the new API
1302            is not fully backwards compatible, so out-of-tree driver wrappers
1303            will need modifications
1304          * cleaned up various module interfaces
1305          * merge hostapd and wpa_supplicant developers' documentation into a
1306            single document
1307          * nl80211: use explicit deauthentication to clear cfg80211 state to
1308            avoid issues when roaming between APs
1309          * dbus: major design changes in the new D-Bus API
1310            (fi.w1.wpa_supplicant1)
1311          * nl80211: added support for IBSS networks
1312          * added internal debugging mechanism with backtrace support and memory
1313            allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y)
1314          * added WPS ER unsubscription command to more cleanly unregister from
1315            receiving UPnP events when ER is terminated
1316          * cleaned up AP mode operations to avoid need for virtual driver_ops
1317            wrapper
1318          * added BSS table to maintain more complete scan result information
1319            over multiple scans (that may include only partial results)
1320          * wpa_gui-qt4: update Peers dialog information more dynamically while
1321            the dialog is kept open
1322          * fixed PKCS#12 use with OpenSSL 1.0.0
1323          * driver_wext: Added cfg80211-specific optimization to avoid some
1324            unnecessary scans and to speed up association
1325
13262009-11-21 - v0.7.0
1327          * increased wpa_cli ping interval to 5 seconds and made this
1328            configurable with a new command line options (-G<seconds>)
1329          * fixed scan buffer processing with WEXT to handle up to 65535
1330            byte result buffer (previously, limited to 32768 bytes)
1331          * allow multiple driver wrappers to be specified on command line
1332            (e.g., -Dnl80211,wext); the first one that is able to initialize the
1333            interface will be used
1334          * added support for multiple SSIDs per scan request to optimize
1335            scan_ssid=1 operations in ap_scan=1 mode (i.e., search for hidden
1336            SSIDs); this requires driver support and can currently be used only
1337            with nl80211
1338          * added support for WPS USBA out-of-band mechanism with USB Flash
1339            Drives (UFD) (CONFIG_WPS_UFD=y)
1340          * driver_ndis: add PAE group address to the multicast address list to
1341            fix wired IEEE 802.1X authentication
1342          * fixed IEEE 802.11r key derivation function to match with the standard
1343            (note: this breaks interoperability with previous version) [Bug 303]
1344          * added better support for drivers that allow separate authentication
1345            and association commands (e.g., mac80211-based Linux drivers with
1346            nl80211; SME in wpa_supplicant); this allows over-the-air FT protocol
1347            to be used (IEEE 802.11r)
1348          * fixed SHA-256 based key derivation function to match with the
1349            standard when using CCMP (for IEEE 802.11r and IEEE 802.11w)
1350            (note: this breaks interoperability with previous version) [Bug 307]
1351          * use shared driver wrapper files with hostapd
1352          * added AP mode functionality (CONFIG_AP=y) with mode=2 in the network
1353            block; this can be used for open and WPA2-Personal networks
1354            (optionally, with WPS); this links in parts of hostapd functionality
1355            into wpa_supplicant
1356          * wpa_gui-qt4: added new Peers dialog to show information about peers
1357            (other devices, including APs and stations, etc. in the neighborhood)
1358          * added support for WPS External Registrar functionality (configure APs
1359            and enroll new devices); can be used with wpa_gui-qt4 Peers dialog
1360            and wpa_cli commands wps_er_start, wps_er_stop, wps_er_pin,
1361            wps_er_pbc, wps_er_learn
1362            (this can also be used with a new 'none' driver wrapper if no
1363            wireless device or IEEE 802.1X on wired is needed)
1364          * driver_nl80211: multiple updates to provide support for new Linux
1365            nl80211/mac80211 functionality
1366          * updated management frame protection to use IEEE Std 802.11w-2009
1367          * fixed number of small WPS issues and added workarounds to
1368            interoperate with common deployed broken implementations
1369          * added support for NFC out-of-band mechanism with WPS
1370          * driver_ndis: fixed wired IEEE 802.1X authentication with PAE group
1371            address frames
1372          * added preliminary support for IEEE 802.11r RIC processing
1373          * added support for specifying subset of enabled frequencies to scan
1374            (scan_freq option in the network configuration block); this can speed
1375            up scanning process considerably if it is known that only a small
1376            subset of channels is actually used in the network (this is currently
1377            supported only with -Dnl80211)
1378          * added a workaround for race condition between receiving the
1379            association event and the following EAPOL-Key
1380          * added background scan and roaming infrastructure to allow
1381            network-specific optimizations to be used to improve roaming within
1382            an ESS (same SSID)
1383          * added new DBus interface (fi.w1.wpa_supplicant1)
1384
13852009-01-06 - v0.6.7
1386          * added support for Wi-Fi Protected Setup (WPS)
1387            (wpa_supplicant can now be configured to act as a WPS Enrollee to
1388            enroll credentials for a network using PIN and PBC methods; in
1389            addition, wpa_supplicant can act as a wireless WPS Registrar to
1390            configure an AP); WPS support can be enabled by adding CONFIG_WPS=y
1391            into .config and setting the runtime configuration variables in
1392            wpa_supplicant.conf (see WPS section in the example configuration
1393            file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to
1394            manage WPS negotiation; see README-WPS for more details
1395          * added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
1396          * added support for using driver_test over UDP socket
1397          * fixed PEAPv0 Cryptobinding interoperability issue with Windows Server
1398            2008 NPS; optional cryptobinding is now enabled (again) by default
1399          * fixed PSK editing in wpa_gui
1400          * changed EAP-GPSK to use the IANA assigned EAP method type 51
1401          * added a Windows installer that includes WinPcap and all the needed
1402            DLLs; in addition, it set up the registry automatically so that user
1403            will only need start wpa_gui to get prompted to start the wpasvc
1404            servide and add a new interface if needed through wpa_gui dialog
1405          * updated management frame protection to use IEEE 802.11w/D7.0
1406
14072008-11-23 - v0.6.6
1408          * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
1409            (can be used to simulate test SIM/USIM card with a known private key;
1410            enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
1411            and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
1412          * added a new network configuration option, wpa_ptk_rekey, that can be
1413            used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
1414            against TKIP deficiencies
1415          * added an optional mitigation mechanism for certain attacks against
1416            TKIP by delaying Michael MIC error reports by a random amount of time
1417            between 0 and 60 seconds; this can be enabled with a build option
1418            CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
1419          * fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
1420            not bytes
1421          * updated OpenSSL code for EAP-FAST to use an updated version of the
1422            session ticket overriding API that was included into the upstream
1423            OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
1424            needed with that version anymore)
1425          * updated userspace MLME instructions to match with the current Linux
1426            mac80211 implementation; please also note that this can only be used
1427            with driver_nl80211.c (the old code from driver_wext.c was removed)
1428          * added support (Linux only) for RoboSwitch chipsets (often found in
1429            consumer grade routers); driver interface 'roboswitch'
1430          * fixed canceling of PMKSA caching when using drivers that generate
1431            RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
1432            about
1433
14342008-11-01 - v0.6.5
1435          * added support for SHA-256 as X.509 certificate digest when using the
1436            internal X.509/TLSv1 implementation
1437          * updated management frame protection to use IEEE 802.11w/D6.0
1438          * added support for using SHA256-based stronger key derivation for WPA2
1439            (IEEE 802.11w)
1440          * fixed FT (IEEE 802.11r) authentication after a failed association to
1441            use correct FTIE
1442          * added support for configuring Phase 2 (inner/tunneled) authentication
1443            method with wpa_gui-qt4
1444
14452008-08-10 - v0.6.4
1446          * added support for EAP Sequences in EAP-FAST Phase 2
1447          * added support for using TNC with EAP-FAST
1448          * added driver_ps3 for the PS3 Linux wireless driver
1449          * added support for optional cryptobinding with PEAPv0
1450          * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
1451            allow fallback to full handshake if server rejects PAC-Opaque
1452          * added fragmentation support for EAP-TNC
1453          * added support for parsing PKCS #8 formatted private keys into the
1454            internal TLS implementation (both PKCS #1 RSA key and PKCS #8
1455            encapsulated RSA key can now be used)
1456          * added option of using faster, but larger, routines in the internal
1457            LibTomMath (for internal TLS implementation) to speed up DH and RSA
1458            calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
1459          * fixed race condition between disassociation event and group key
1460            handshake to avoid getting stuck in incorrect state [Bug 261]
1461          * fixed opportunistic key caching (proactive_key_caching)
1462
14632008-02-22 - v0.6.3
1464          * removed 'nai' and 'eappsk' network configuration variables that were
1465            previously used for configuring user identity and key for EAP-PSK,
1466            EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
1467            replacement for 'nai' (if old configuration used a separate
1468            'identity' value, that would now be configured as
1469            'anonymous_identity'). 'password' field is now used as the
1470            replacement for 'eappsk' (it can also be set using hexstring to
1471            present random binary data)
1472          * removed '-w' command line parameter (wait for interface to be added,
1473            if needed); cleaner way of handling this functionality is to use an
1474            external mechanism (e.g., hotplug scripts) that start wpa_supplicant
1475            when an interface is added
1476          * updated FT support to use the latest draft, IEEE 802.11r/D9.0
1477          * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
1478            indicating when new scan results become available
1479          * added new ctrl_iface command, BSS, to allow scan results to be
1480            fetched without hitting the message size limits (this command
1481            can be used to iterate through the scan results one BSS at the time)
1482          * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
1483            attributes in EAP-SIM Start/Response when using fast reauthentication
1484          * fixed EAPOL not to end up in infinite loop when processing dynamic
1485            WEP keys with IEEE 802.1X
1486          * fixed problems in getting NDIS events from WMI on Windows 2000
1487
14882008-01-01 - v0.6.2
1489          * added support for Makefile builds to include debug-log-to-a-file
1490            functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
1491          * fixed EAP-SIM and EAP-AKA message parser to validate attribute
1492            lengths properly to avoid potential crash caused by invalid messages
1493          * added data structure for storing allocated buffers (struct wpabuf);
1494            this does not affect wpa_supplicant usage, but many of the APIs
1495            changed and various interfaces (e.g., EAP) is not compatible with old
1496            versions
1497          * added support for protecting EAP-AKA/Identity messages with
1498            AT_CHECKCODE (optional feature in RFC 4187)
1499          * added support for protected result indication with AT_RESULT_IND for
1500            EAP-SIM and EAP-AKA (phase1="result_ind=1")
1501          * added driver_wext workaround for race condition between scanning and
1502            association with drivers that take very long time to scan all
1503            channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
1504            using a longer hardcoded timeout for the scan if the driver supports
1505            notifications for scan completion (SIOCGIWSCAN event); this helps,
1506            e.g., in cases where wpa_supplicant and madwifi driver ended up in
1507            loop where the driver did not even try to associate
1508          * stop EAPOL timer tick when no timers are in use in order to reduce
1509            power consumption (no need to wake up the process once per second)
1510            [Bug 237]
1511          * added support for privilege separation (run only minimal part of
1512            wpa_supplicant functionality as root and rest as unprivileged,
1513            non-root process); see 'Privilege separation' in README for details;
1514            this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
1515            in .config
1516          * changed scan results data structure to include all information
1517            elements to make it easier to support new IEs; old get_scan_result()
1518            driver_ops is still supported for backwards compatibility (results
1519            are converted internally to the new format), but all drivers should
1520            start using the new get_scan_results2() to make them more likely to
1521            work with new features
1522          * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
1523            application, i.e., it does not require Qt3Support anymore; Windows
1524            binary of wpa_gui.exe is now from this directory and only requires
1525            QtCore4.dll and QtGui4.dll libraries
1526          * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
1527            available as a separate package to make wpa_gui installation easier:
1528            http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
1529          * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
1530            only shared key/password authentication is supported in this version
1531
15322007-11-24 - v0.6.1
1533          * added support for configuring password as NtPasswordHash
1534            (16-byte MD4 hash of password) in hash:<32 hex digits> format
1535          * added support for fallback from abbreviated TLS handshake to
1536            full handshake when using EAP-FAST (e.g., due to an expired
1537            PAC-Opaque)
1538          * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
1539            draft (draft-ietf-emu-eap-gpsk-07.txt)
1540          * added support for drivers that take care of RSN 4-way handshake
1541            internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
1542            WPA_ALG_PMK in set_key)
1543          * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
1544            .config); this version supports only ap_scan=2 mode and allow the
1545            driver to take care of the 4-way handshake
1546          * fixed a buffer overflow in parsing TSF from scan results when using
1547            driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
1548            [Bug 232]
1549          * updated FT support to use the latest draft, IEEE 802.11r/D8.0
1550          * fixed an integer overflow issue in the ASN.1 parser used by the
1551            (experimental) internal TLS implementation to avoid a potential
1552            buffer read overflow
1553          * fixed a race condition with -W option (wait for a control interface
1554            monitor before starting) that could have caused the first messages to
1555            be lost
1556          * added support for processing TNCC-TNCS-Messages to report
1557            recommendation (allow/none/isolate) when using TNC [Bug 243]
1558
15592007-05-28 - v0.6.0
1560          * added network configuration parameter 'frequency' for setting
1561            initial channel for IBSS (adhoc) networks
1562          * added experimental IEEE 802.11r/D6.0 support
1563          * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
1564          * updated EAP-PSK to use the IANA-allocated EAP type 47
1565          * fixed EAP-PAX key derivation
1566          * fixed EAP-PSK bit ordering of the Flags field
1567          * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
1568            tunnelled identity request (previously, the identifier from the outer
1569            method was used, not the tunnelled identifier which could be
1570            different)
1571          * added support for fragmentation of outer TLS packets during Phase 2
1572            of EAP-PEAP/TTLS/FAST
1573          * fixed EAP-TTLS AVP parser processing for too short AVP lengths
1574          * added support for EAP-FAST authentication with inner methods that
1575            generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
1576            for PAC provisioning)
1577          * added support for authenticated EAP-FAST provisioning
1578          * added support for configuring maximum number of EAP-FAST PACs to
1579            store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
1580          * added support for storing EAP-FAST PACs in binary format
1581            (fast_pac_format=binary in phase1 string)
1582          * fixed dbus ctrl_iface to validate message interface before
1583            dispatching to avoid a possible segfault [Bug 190]
1584          * fixed PeerKey key derivation to use the correct PRF label
1585          * updated Windows binary build to link against OpenSSL 0.9.8d and
1586            added support for EAP-FAST
1587          * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
1588            draft (draft-ietf-emu-eap-gpsk-04.txt)
1589          * fixed EAP-AKA Notification processing to allow Notification to be
1590            processed after AKA Challenge response has been sent
1591          * updated to use IEEE 802.11w/D2.0 for management frame protection
1592            (still experimental)
1593          * fixed EAP-TTLS implementation not to crash on use of freed memory
1594            if TLS library initialization fails
1595          * added support for EAP-TNC (Trusted Network Connect)
1596            (this version implements the EAP-TNC method and EAP-TTLS changes
1597            needed to run two methods in sequence (IF-T) and the IF-IMC and
1598            IF-TNCCS interfaces from TNCC)
1599
16002006-11-24 - v0.5.6
1601          * added experimental, integrated TLSv1 client implementation with the
1602            needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
1603            setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
1604            .config); this can be useful, e.g., if the target system does not
1605            have a suitable TLS library and a minimal code size is required
1606            (total size of this internal TLS/crypto code is bit under 50 kB on
1607            x86 and the crypto code is shared by rest of the supplicant so some
1608            of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
1609          * removed STAKey handshake since PeerKey handshake has replaced it in
1610            IEEE 802.11ma and there are no known deployments of STAKey
1611          * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
1612            draft (draft-ietf-emu-eap-gpsk-01.txt)
1613          * added preliminary implementation of IEEE 802.11w/D1.0 (management
1614            frame protection)
1615            (Note: this requires driver support to work properly.)
1616            (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
1617          * fixed Windows named pipes ctrl_iface to not stop listening for
1618            commands if client program opens a named pipe and closes it
1619            immediately without sending a command
1620          * fixed USIM PIN status determination for the case that PIN is not
1621            needed (this allows EAP-AKA to be used with USIM cards that do not
1622            use PIN)
1623          * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
1624            be used with cards that do not support file selection based on
1625            partial AID
1626          * added support for matching the subjectAltName of the authentication
1627            server certificate against multiple name components (e.g.,
1628            altsubject_match="DNS:server.example.com;DNS:server2.example.com")
1629          * fixed EAP-SIM/AKA key derivation for re-authentication case (only
1630            affects IEEE 802.1X with dynamic WEP keys)
1631          * changed ctrl_iface network configuration 'get' operations to not
1632            return password/key material; if these fields are requested, "*"
1633            will be returned if the password/key is set, but the value of the
1634            parameter is not exposed
1635
16362006-08-27 - v0.5.5
1637          * added support for building Windows version with UNICODE defined
1638            (wide-char functions)
1639          * driver_ndis: fixed static WEP configuration to avoid race condition
1640            issues with some NDIS drivers between association and setting WEP
1641            keys
1642          * driver_ndis: added validation for IELength value in scan results to
1643            avoid crashes when using buggy NDIS drivers [Bug 165]
1644          * fixed Release|Win32 target in the Visual Studio project files
1645            (previously, only Debug|Win32 target was set properly)
1646          * changed control interface API call wpa_ctrl_pending() to allow it to
1647            return -1 on error (e.g., connection lost); control interface clients
1648            will need to make sure that they verify that the value is indeed >0
1649            when determining whether there are pending messages
1650          * added an alternative control interface backend for Windows targets:
1651            Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
1652            control interface mechanism for Windows builds (previously, UDP to
1653            localhost was used)
1654          * changed ctrl_interface configuration for UNIX domain sockets:
1655            - deprecated ctrl_interface_group variable (it may be removed in
1656              future versions)
1657            - allow both directory and group be configured with ctrl_interface
1658              in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
1659            - ctrl_interface=/var/run/wpa_supplicant is still supported for the
1660              case when group is not changed
1661          * added support for controlling more than one interface per process in
1662            Windows version
1663          * added a workaround for a case where the AP is using unknown address
1664            (e.g., MAC address of the wired interface) as the source address for
1665            EAPOL-Key frames; previously, that source address was used as the
1666            destination for EAPOL-Key frames and in key derivation; now, BSSID is
1667            used even if the source address does not match with it
1668            (this resolves an interoperability issue with Thomson SpeedTouch 580)
1669          * added a workaround for UDP-based control interface (which was used in
1670            Windows builds before this release) to prevent packets with forged
1671            addresses from being accepted as local control requests
1672          * removed ndis_events.cpp and possibility of using external
1673            ndis_events.exe; C version (ndis_events.c) is fully functional and
1674            there is no desire to maintain two separate versions of this
1675            implementation
1676          * ndis_events: Changed NDIS event notification design to use WMI to
1677            learn the adapter description through Win32_PnPEntity class; this
1678            should fix some cases where the adapter name was not recognized
1679            correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
1680            USB) [Bug 113]
1681          * fixed selection of the first network in ap_scan=2 mode; previously,
1682            wpa_supplicant could get stuck in SCANNING state when only the first
1683            network for enabled (e.g., after 'wpa_cli select_network 0')
1684          * winsvc: added support for configuring ctrl_interface parameters in
1685            registry (ctrl_interface string value in
1686            HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
1687            required to enable control interface (previously, this was hardcoded
1688            to be enabled)
1689          * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
1690          * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
1691
16922006-06-20 - v0.5.4
1693          * fixed build with CONFIG_STAKEY=y [Bug 143]
1694          * added support for doing MLME (IEEE 802.11 management frame
1695            processing) in wpa_supplicant when using Devicescape IEEE 802.11
1696            stack (wireless-dev.git tree)
1697          * added a new network block configuration option, fragment_size, to
1698            configure the maximum EAP fragment size
1699          * driver_ndis: Disable WZC automatically for the selected interface to
1700            avoid conflicts with two programs trying to control the radio; WZC
1701            will be re-enabled (if it was enabled originally) when wpa_supplicant
1702            is terminated
1703          * added an experimental TLSv1 client implementation
1704            (CONFIG_TLS=internal) that can be used instead of an external TLS
1705            library, e.g., to reduce total size requirement on systems that do
1706            not include any TLS library by default (this is not yet complete;
1707            basic functionality is there, but certificate validation is not yet
1708            included)
1709          * added PeerKey handshake implementation for IEEE 802.11e
1710            direct link setup (DLS) to replace STAKey handshake
1711          * fixed WPA PSK update through ctrl_iface for the case where the old
1712            PSK was derived from an ASCII passphrase and the new PSK is set as
1713            a raw PSK (hex string)
1714          * added new configuration option for identifying which network block
1715            was used (id_str in wpa_supplicant.conf; included on
1716            WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
1717            variable in wpa_cli action scripts; in addition WPA_ID variable is
1718            set to the current unique identifier that wpa_supplicant assigned
1719            automatically for the network and that can be used with
1720            GET_NETWORK/SET_NETWORK ctrl_iface commands)
1721          * wpa_cli action script is now called only when the connect/disconnect
1722            status changes or when associating with a different network
1723          * fixed configuration parser not to remove CCMP from group cipher list
1724            if WPA-None (adhoc) is used (pairwise=NONE in that case)
1725          * fixed integrated NDIS events processing not to hang the process due
1726            to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
1727          * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
1728            draft-clancy-emu-eap-shared-secret-00.txt)
1729          * added Microsoft Visual Studio 2005 solution and project files for
1730            build wpa_supplicant for Windows (see vs2005 subdirectory)
1731          * eloop_win: fixed unregistration of Windows events
1732          * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
1733            at the end of RSN pre-authentication and added unregistration of
1734            a Windows event to avoid getting eloop_win stuck with an invalid
1735            handle
1736          * driver_ndis: added support for selecting AP based on BSSID
1737          * added new environmental variable for wpa_cli action scripts:
1738            WPA_CTRL_DIR is the current control interface directory
1739          * driver_ndis: added support for using NDISUIO instead of WinPcap for
1740            OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
1741            l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
1742            wpa_supplicant without requiring WinPcap; note that using NDISUIO
1743            requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
1744            only one application to open the device
1745          * changed NDIS driver naming to only include device GUID, e.g.,
1746            {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
1747            specific \Device\NPF_ prefix before the GUID; the prefix is still
1748            allowed for backwards compatibility, but it is not required anymore
1749            when specifying the interface
1750          * driver_ndis: re-initialize driver interface is the adapter is removed
1751            and re-inserted [Bug 159]
1752          * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
1753            big endian hosts [Bug 146]
1754
17552006-04-27 - v0.5.3
1756          * fixed EAP-GTC response to include correct user identity when run as
1757            phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
1758          * driver_ndis: Fixed encryption mode configuration for unencrypted
1759            networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
1760            refused to associate with open networks) [Bug 106]
1761          * driver_ndis: use BSSID OID polling to detect when IBSS network is
1762            formed even when ndis_events code is included since some NDIS drivers
1763            do not generate media connect events in IBSS mode
1764          * config_winreg: allow global ctrl_interface parameter to be configured
1765            in Windows registry
1766          * config_winreg: added support for saving configuration data into
1767            Windows registry
1768          * added support for controlling network device operational state
1769            (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
1770            http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
1771            that can use this information)
1772          * driver_wext: added support for WE-21 change to SSID configuration
1773          * driver_wext: fixed privacy configuration for static WEP keys mode
1774            [Bug 140]
1775          * added an optional driver_ops callback for MLME-SETPROTECTION.request
1776            primitive
1777          * added support for EAP-SAKE (no EAP method number allocated yet, so
1778            this is using the same experimental type 255 as EAP-PSK)
1779          * added support for dynamically loading EAP methods (.so files) instead
1780            of requiring them to be statically linked in; this is disabled by
1781            default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
1782            on how to use this)
1783
17842006-03-19 - v0.5.2
1785          * do not try to use USIM APDUs when initializing PC/SC for SIM card
1786            access for a network that has not enabled EAP-AKA
1787          * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
1788            v0.5.1 due to the new support for expanded EAP types)
1789          * added support for generating EAP Expanded Nak
1790          * try to fetch scan results once before requesting new scan when
1791            starting up in ap_scan=1 mode (this can speed up initial association
1792            a lot with, e.g., madwifi-ng driver)
1793          * added support for receiving EAPOL frames from a Linux bridge
1794            interface (-bbr0 on command line)
1795          * fixed EAPOL re-authentication for sessions that used PMKSA caching
1796          * changed EAP method registration to use a dynamic list of methods
1797            instead of a static list generated at build time
1798          * fixed PMKSA cache deinitialization not to use freed memory when
1799            removing PMKSA entries
1800          * fixed a memory leak in EAP-TTLS re-authentication
1801          * reject WPA/WPA2 message 3/4 if it does not include any valid
1802            WPA/RSN IE
1803          * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
1804            if the driver does not support SIOCSIWAUTH
1805
18062006-01-29 - v0.5.1
1807          * driver_test: added better support for multiple APs and STAs by using
1808            a directory with sockets that include MAC address for each device in
1809            the name (driver_param=test_dir=/tmp/test)
1810          * added support for EAP expanded type (vendor specific EAP methods)
1811          * added AP_SCAN command into ctrl_iface so that ap_scan configuration
1812            option can be changed if needed
1813          * wpa_cli/wpa_gui: skip non-socket files in control directory when
1814            using UNIX domain sockets; this avoids selecting an incorrect
1815            interface (e.g., a PID file could be in this directory, even though
1816            use of this directory for something else than socket files is not
1817            recommended)
1818          * fixed TLS library deinitialization after RSN pre-authentication not
1819            to disable TLS library for normal authentication
1820          * driver_wext: Remove null-termination from SSID length if the driver
1821            used it; some Linux drivers do this and they were causing problems in
1822            wpa_supplicant not finding matching configuration block. This change
1823            would break a case where the SSID actually ends in '\0', but that is
1824            not likely to happen in real use.
1825          * fixed PMKSA cache processing not to trigger deauthentication if the
1826            current PMKSA cache entry is replaced with a valid new entry
1827          * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
1828            EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
1829            ap_scan=2)
1830
18312005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
1832          * added experimental STAKey handshake implementation for IEEE 802.11e
1833            direct link setup (DLS); note: this is disabled by default in both
1834            build and runtime configuration (can be enabled with CONFIG_STAKEY=y
1835            and stakey=1)
1836          * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
1837            decrypt AT_ENCR_DATA attributes correctly
1838          * fixed EAP-AKA to allow resynchronization within the same session
1839          * made code closer to ANSI C89 standard to make it easier to port to
1840            other C libraries and compilers
1841          * started moving operating system or C library specific functions into
1842            wrapper functions defined in os.h and implemented in os_*.c to make
1843            code more portable
1844          * wpa_supplicant can now be built with Microsoft Visual C++
1845            (e.g., with the freely available Toolkit 2003 version or Visual
1846            C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
1847            example makefile for nmake
1848          * added support for using Windows registry for command line parameters
1849            (CONFIG_MAIN=main_winsvc) and configuration data
1850            (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
1851            contents; this version can be run both as a Windows service and as a
1852            normal application; 'wpasvc.exe app' to start as applicant,
1853            'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
1854            'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
1855            unregister a service
1856          * made it possible to link ndis_events.exe functionality into
1857            wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
1858          * added better support for multiple control interface backends
1859            (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
1860          * fixed PC/SC code to use correct length for GSM AUTH command buffer
1861            and to not use pioRecvPci with SCardTransmit() calls; these were not
1862            causing visible problems with pcsc-lite, but Windows Winscard.dll
1863            refused the previously used parameters; this fixes EAP-SIM and
1864            EAP-AKA authentication using SIM/USIM card under Windows
1865          * added new event loop implementation for Windows using
1866            WaitForMultipleObject() instead of select() in order to allow waiting
1867            for non-socket objects; this can be selected with
1868            CONFIG_ELOOP=eloop_win in .config
1869          * added support for selecting l2_packet implementation in .config
1870            (CONFIG_L2_PACKET; following options are available now: linux, pcap,
1871            winpcap, freebsd, none)
1872          * added new l2_packet implementation for WinPcap
1873            (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
1874            reduce latency in EAPOL receive processing from about 100 ms to about
1875            3 ms
1876          * added support for EAP-FAST key derivation using other ciphers than
1877            RC4-128-SHA for authentication and AES128-SHA for provisioning
1878          * added support for configuring CA certificate as DER file and as a
1879            configuration blob
1880          * fixed private key configuration as configuration blob and added
1881            support for using PKCS#12 as a blob
1882          * tls_gnutls: added support for using PKCS#12 files; added support for
1883            session resumption
1884          * added support for loading trusted CA certificates from Windows
1885            certificate store: ca_cert="cert_store://<name>", where <name> is
1886            likely CA (Intermediate CA certificates) or ROOT (root certificates)
1887          * added C version of ndis_events.cpp and made it possible to build this
1888            with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
1889            easily on cross-compilation builds
1890          * added wpasvc.exe into Windows binary release; this is an alternative
1891            version of wpa_supplicant.exe with configuration backend using
1892            Windows registry and with the entry point designed to run as a
1893            Windows service
1894          * integrated ndis_events.exe functionality into wpa_supplicant.exe and
1895            wpasvc.exe and removed this additional tool from the Windows binary
1896            release since it is not needed anymore
1897          * load winscard.dll functions dynamically when building with MinGW
1898            since MinGW does not yet include winscard library
1899
19002005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
1901          * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
1902            and WinPcap to receive frames sent to PAE group address
1903          * disable EAP state machine when IEEE 802.1X authentication is not used
1904            in order to get rid of bogus "EAP failed" messages
1905          * fixed OpenSSL error reporting to go through all pending errors to
1906            avoid confusing reports of old errors being reported at later point
1907            during handshake
1908          * fixed configuration file updating to not write empty variables
1909            (e.g., proto or key_mgmt) that the file parser would not accept
1910          * fixed ADD_NETWORK ctrl_iface command to use the same default values
1911            for variables as empty network definitions read from config file
1912            would get
1913          * fixed EAP state machine to not discard EAP-Failure messages in many
1914            cases (e.g., during TLS handshake)
1915          * fixed a infinite loop in private key reading if the configured file
1916            cannot be parsed successfully
1917          * driver_madwifi: added support for madwifi-ng
1918          * wpa_gui: do not display password/PSK field contents
1919          * wpa_gui: added CA certificate configuration
1920          * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
1921          * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
1922            the new AP is using different WPA/RSN IE
1923          * use longer timeout for IEEE 802.11 association to avoid problems with
1924            drivers that may take more than five second to associate
1925
19262005-10-27 - v0.4.6
1927          * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
1928            RSN IE, but WPA IE would match with wpa_supplicant configuration
1929          * added support for named configuration blobs in order to avoid having
1930            to use file system for external files (e.g., certificates);
1931            variables can be set to "blob://<blob name>" instead of file path to
1932            use a named blob; supported fields: pac_file, client_cert,
1933            private_key
1934          * fixed RSN pre-authentication (it was broken in the clean up of WPA
1935            state machine interface in v0.4.5)
1936          * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
1937            sure the driver configures broadcast decryption correctly
1938          * added ca_path (and ca_path2) configuration variables that can be used
1939            to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
1940            system-wide trusted CA list
1941          * added support for starting wpa_supplicant without a configuration
1942            file (-C argument must be used to set ctrl_interface parameter for
1943            this case; in addition, -p argument can be used to provide
1944            driver_param; these new arguments can also be used with a
1945            configuration to override the values from the configuration)
1946          * added global control interface that can be optionally used for adding
1947            and removing network interfaces dynamically (-g command line argument
1948            for both wpa_supplicant and wpa_cli) without having to restart
1949            wpa_supplicant process
1950          * wpa_gui:
1951            - try to save configuration whenever something is modified
1952            - added WEP key configuration
1953            - added possibility to edit the current network configuration
1954          * driver_ndis: fixed driver polling not to increase frequency on each
1955            received EAPOL frame due to incorrectly cancelled timeout
1956          * added simple configuration file examples (in examples subdirectory)
1957          * fixed driver_wext.c to filter wireless events based on ifindex to
1958            avoid interfaces receiving events from other interfaces
1959          * delay sending initial EAPOL-Start couple of seconds to speed up
1960            authentication for the most common case of Authenticator starting
1961            EAP authentication immediately after association
1962
19632005-09-25 - v0.4.5
1964          * added a workaround for clearing keys with ndiswrapper to allow
1965            roaming from WPA enabled AP to plaintext one
1966          * added docbook documentation (doc/docbook) that can be used to
1967            generate, e.g., man pages
1968          * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
1969            PF_PACKET in order to prepare for network devices that do not use
1970            Ethernet headers (e.g., network stack that includes IEEE 802.11
1971            header in the frames)
1972          * use receipt of EAPOL-Key frame as a lower layer success indication
1973            for EAP state machine to allow recovery from dropped EAP-Success
1974            frame
1975          * cleaned up internal EAPOL frame processing by not including link
1976            layer (Ethernet) header during WPA and EAPOL/EAP processing; this
1977            header is added only when transmitted the frame; this makes it easier
1978            to use wpa_supplicant on link layers that use different header than
1979            Ethernet
1980          * updated EAP-PSK to use draft 9 by default since this can now be
1981            tested with hostapd; removed support for draft 3, including
1982            server_nai configuration option from network blocks
1983          * driver_wired: add PAE address to the multicast address list in order
1984            to be able to receive EAPOL frames with drivers that do not include
1985            these multicast addresses by default
1986          * driver_wext: add support for WE-19
1987          * added support for multiple configuration backends (CONFIG_BACKEND
1988            option); currently, only 'file' is supported (i.e., the format used
1989            in wpa_supplicant.conf)
1990          * added support for updating configuration ('wpa_cli save_config');
1991            this is disabled by default and can be enabled with global
1992            update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
1993            and wpa_gui to store the configuration changes in a permanent store
1994          * added GET_NETWORK ctrl_iface command
1995            (e.g., 'wpa_cli get_network 0 ssid')
1996
19972005-08-21 - v0.4.4
1998          * replaced OpenSSL patch for EAP-FAST support
1999            (openssl-tls-extensions.patch) with a more generic and correct
2000            patch (the new patch is not compatible with the previous one, so the
2001            OpenSSL library will need to be patched with the new patch in order
2002            to be able to build wpa_supplicant with EAP-FAST support)
2003          * added support for using Windows certificate store (through CryptoAPI)
2004            for client certificate and private key operations (EAP-TLS)
2005            (see wpa_supplicant.conf for more information on how to configure
2006            this with private_key)
2007          * ported wpa_gui to Windows
2008          * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
2009            built with the open source version of the Qt4 for Windows
2010          * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
2011            with drivers that do not support WPA
2012          * ndis_events: fixed Windows 2000 support
2013          * added support for enabling/disabling networks from the list of all
2014            configured networks ('wpa_cli enable_network <network id>' and
2015            'wpa_cli disable_network <network id>')
2016          * added support for adding and removing network from the current
2017            configuration ('wpa_cli add_network' and 'wpa_cli remove_network
2018            <network id>'); added networks are disabled by default and they can
2019            be enabled with enable_network command once the configuration is done
2020            for the new network; note: configuration file is not yet updated, so
2021            these new networks are lost when wpa_supplicant is restarted
2022          * added support for setting network configuration parameters through
2023            the control interface, for example:
2024            wpa_cli set_network 0 ssid "\"my network\""
2025          * fixed parsing of strings that include both " and # within double
2026            quoted area (e.g., "start"#end")
2027          * added EAP workaround for PEAP session resumption: allow outer,
2028            i.e., not tunneled, EAP-Success to terminate session since; this can
2029            be disabled with eap_workaround=0
2030            (this was allowed for PEAPv1 before, but now it is also allowed for
2031            PEAPv0 since at least one RADIUS authentication server seems to be
2032            doing this for PEAPv0, too)
2033          * wpa_gui: added preliminary support for adding new networks to the
2034            wpa_supplicant configuration (double click on the scan results to
2035            open network configuration)
2036
20372005-06-26 - v0.4.3
2038          * removed interface for external EAPOL/EAP supplicant (e.g.,
2039            Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
2040            anymore and is unlikely to be used by anyone
2041          * driver_ndis: fixed WinPcap 3.0 support
2042          * fixed build with CONFIG_DNET_PCAP=y on Linux
2043          * l2_packet: moved different implementations into separate files
2044            (l2_packet_*.c)
2045
20462005-06-12 - v0.4.2
2047          * driver_ipw: updated driver structures to match with ipw2200-1.0.4
2048            (note: ipw2100-1.1.0 is likely to require an update to work with
2049            this)
2050          * added support for using ap_scan=2 mode with multiple network blocks;
2051            wpa_supplicant will go through the networks one by one until the
2052            driver reports a successful association; this uses the same order for
2053            networks as scan_ssid=1 scans, i.e., the priority field is ignored
2054            and the network block order in the file is used instead
2055          * fixed a potential issue in RSN pre-authentication ending up using
2056            freed memory if pre-authentication times out
2057          * added support for matching alternative subject name extensions of the
2058            authentication server certificate; new configuration variables
2059            altsubject_match and altsubject_match2
2060          * driver_ndis: added support for IEEE 802.1X authentication with wired
2061            NDIS drivers
2062          * added support for querying private key password (EAP-TLS) through the
2063            control interface (wpa_cli/wpa_gui) if one is not included in the
2064            configuration file
2065          * driver_broadcom: fixed couple of memory leaks in scan result
2066            processing
2067          * EAP-PAX is now registered as EAP type 46
2068          * fixed EAP-PAX MAC calculation
2069          * fixed EAP-PAX CK and ICK key derivation
2070          * added support for using password with EAP-PAX (as an alternative to
2071            entering key with eappsk); SHA-1 hash of the password will be used as
2072            the key in this case
2073          * added support for arbitrary driver interface parameters through the
2074            configuration file with a new driver_param field; this adds a new
2075            driver_ops function set_param()
2076          * added possibility to override l2_packet module with driver interface
2077            API (new send_eapol handler); this can be used to implement driver
2078            specific TX/RX functions for EAPOL frames
2079          * fixed ctrl_interface_group processing for the case where gid is
2080            entered as a number, not group name
2081          * driver_test: added support for testing hostapd with wpa_supplicant
2082            by using test driver interface without any kernel drivers or network
2083            cards
2084
20852005-05-22 - v0.4.1
2086          * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
2087            packets to be encrypted; this was apparently broken by the changed
2088            ioctl order in v0.4.0
2089          * driver_madwifi: added preliminary support for compiling against 'BSD'
2090            branch of madwifi CVS tree
2091          * added support for EAP-MSCHAPv2 password retries within the same EAP
2092            authentication session
2093          * added support for password changes with EAP-MSCHAPv2 (used when the
2094            password has expired)
2095          * added support for reading additional certificates from PKCS#12 files
2096            and adding them to the certificate chain
2097          * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
2098            were used
2099          * fixed a possible double free in EAP-TTLS fast-reauthentication when
2100            identity or password is entered through control interface
2101          * display EAP Notification messages to user through control interface
2102            with "CTRL-EVENT-EAP-NOTIFICATION" prefix
2103          * added GUI version of wpa_cli, wpa_gui; this is not build
2104            automatically with 'make'; use 'make wpa_gui' to build (this requires
2105            Qt development tools)
2106          * added 'disconnect' command to control interface for setting
2107            wpa_supplicant in state where it will not associate before
2108            'reassociate' command has been used
2109          * added support for selecting a network from the list of all configured
2110            networks ('wpa_cli select_network <network id>'; this disabled all
2111            other networks; to re-enable, 'wpa_cli select_network any')
2112          * added support for getting scan results through control interface
2113          * added EAP workaround for PEAPv1 session resumption: allow outer,
2114            i.e., not tunneled, EAP-Success to terminate session since; this can
2115            be disabled with eap_workaround=0
2116
21172005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
2118          * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
2119            used to reduce the size of the wpa_supplicant considerably if
2120            debugging code is not needed
2121          * fixed EAPOL-Key validation to drop packets with invalid Key Data
2122            Length; such frames could have crashed wpa_supplicant due to buffer
2123            overflow
2124          * added support for wired authentication (IEEE 802.1X on wired
2125            Ethernet); driver interface 'wired'
2126          * obsoleted set_wpa() handler in the driver interface API (it can be
2127            replaced by moving enable/disable functionality into init()/deinit())
2128            (calls to set_wpa() are still present for backwards compatibility,
2129            but they may be removed in the future)
2130          * driver_madwifi: fixed association in plaintext mode
2131          * modified the EAP workaround that accepts EAP-Success with incorrect
2132            Identifier to be even less strict about verification in order to
2133            interoperate with some authentication servers
2134          * added support for sending TLS alerts
2135          * added support for 'any' SSID wildcard; if ssid is not configured or
2136            is set to an empty string, any SSID will be accepted for non-WPA AP
2137          * added support for asking PIN (for SIM) from frontends (e.g.,
2138            wpa_cli); if a PIN is needed, but not included in the configuration
2139            file, a control interface request is sent and EAP processing is
2140            delayed until the PIN is available
2141          * added support for using external devices (e.g., a smartcard) for
2142            private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
2143            new wpa_supplicant.conf variables:
2144            - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
2145            - network: engine, engine_id, key_id
2146          * added experimental support for EAP-PAX
2147          * added monitor mode for wpa_cli (-a<path to a program to run>) that
2148            allows external commands (e.g., shell scripts) to be run based on
2149            wpa_supplicant events, e.g., when authentication has been completed
2150            and data connection is ready; other related wpa_cli arguments:
2151            -B (run in background), -P (write PID file); wpa_supplicant has a new
2152            command line argument (-W) that can be used to make it wait until a
2153            control interface command is received in order to avoid missing
2154            events
2155          * added support for opportunistic WPA2 PMKSA key caching (disabled by
2156            default, can be enabled with proactive_key_caching=1)
2157          * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
2158            Authenticator rejects PMKSA caching attempt and the driver is not
2159            using assoc_info events
2160          * added -P<pid file> argument for wpa_supplicant to write the current
2161            process id into a file
2162
21632005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
2164          * added new phase1 option parameter, include_tls_length=1, to force
2165            wpa_supplicant to add TLS Message Length field to all TLS messages
2166            even if the packet is not fragmented; this may be needed with some
2167            authentication servers
2168          * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
2169            using drivers that take care of AP selection (e.g., when using
2170            ap_scan=2)
2171          * fixed reprocessing of pending request after ctrl_iface requests for
2172            identity/password/otp
2173          * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
2174            EAP-PEAP and EAP-TTLS
2175          * all drivers using driver_wext: set interface up and select Managed
2176            mode when starting wpa_supplicant; set interface down when exiting
2177          * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
2178            ipw2100 and ipw2200; please note that this also changed the
2179            configuration variable in .config to CONFIG_DRIVER_IPW
2180
21812005-01-24 - v0.3.6
2182          * fixed a busy loop introduced in v0.3.5 for scan result processing
2183            when no matching AP is found
2184
21852005-01-23 - v0.3.5
2186          * added a workaround for an interoperability issue with a Cisco AP
2187            when using WPA2-PSK
2188          * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
2189            WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
2190            retransmission of dropped frames)
2191          * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
2192            (e.g., segfault when processing EAPOL-Key frames)
2193          * fixed EAP workaround and fast reauthentication configuration for
2194            RSN pre-authentication; previously these were disabled and
2195            pre-authentication would fail if the used authentication server
2196            requires EAP workarounds
2197          * added support for blacklisting APs that fail or timeout
2198            authentication in ap_scan=1 mode so that all APs are tried in cases
2199            where the ones with strongest signal level are failing authentication
2200          * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
2201            authentication attempt
2202          * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
2203            in the previous authentication (previously, only Phase 1 success was
2204            verified)
2205
22062005-01-09 - v0.3.4
2207          * added preliminary support for IBSS (ad-hoc) mode configuration
2208            (mode=1 in network block); this included a new key_mgmt mode
2209            WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
2210            key management; see wpa_supplicant.conf for more details and an
2211            example on how to configure this (note: this is currently implemented
2212            only for driver_hostapd.c, but the changes should be trivial to add
2213            in associate() handler for other drivers, too (assuming the driver
2214            supports WPA-None)
2215          * added preliminary port for native Windows (i.e., no cygwin) using
2216            mingw
2217
22182005-01-02 - v0.3.3
2219          * added optional support for GNU Readline and History Libraries for
2220            wpa_cli (CONFIG_READLINE)
2221          * cleaned up EAP state machine <-> method interface and number of
2222            small problems with error case processing not terminating on
2223            EAP-Failure but waiting for timeout
2224          * added couple of workarounds for interoperability issues with a
2225            Cisco AP when using WPA2
2226          * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
2227            Note: This requires a patch for openssl to add support for TLS
2228            extensions and number of workarounds for operations without
2229            certificates. Proof of concept type of experimental patch is
2230            included in openssl-tls-extensions.patch.
2231
22322004-12-19 - v0.3.2
2233          * fixed private key loading for cases where passphrase is not set
2234          * fixed Windows/cygwin L2 packet handler freeing; previous version
2235            could cause a segfault when RSN pre-authentication was completed
2236          * added support for PMKSA caching with drivers that generate RSN IEs
2237            (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
2238            but similar code can be easily added to driver_ndiswrapper.c once
2239            ndiswrapper gets full support for RSN PMKSA caching
2240          * improved recovery from PMKID mismatches by requesting full EAP
2241            authentication in case of failed PMKSA caching attempt
2242          * driver_ndis: added support for NDIS NdisMIncidateStatus() events
2243            (this requires that ndis_events is ran while wpa_supplicant is
2244            running)
2245          * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
2246          * added support for driver interfaces to replace the interface name
2247            based on driver/OS specific mapping, e.g., in case of driver_ndis,
2248            this allows the beginning of the adapter description to be used as
2249            the interface name
2250          * added support for CR+LF (Windows-style) line ends in configuration
2251            file
2252          * driver_ndis: enable radio before starting scanning, disable radio
2253            when exiting
2254          * modified association event handler to set portEnabled = FALSE before
2255            clearing port Valid in order to reset EAP state machine and avoid
2256            problems with new authentication getting ignored because of state
2257            machines ending up in AUTHENTICATED/SUCCESS state based on old
2258            information
2259          * added support for driver events to add PMKID candidates in order to
2260            allow drivers to give priority to most likely roaming candidates
2261          * driver_hostap: moved PrivacyInvoked configuration to associate()
2262            function so that this will not be set for plaintext connections
2263          * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
2264            interface can distinguish plaintext and IEEE 802.1X (no WPA)
2265            authentication
2266          * fixed static WEP key configuration to use broadcast/default type for
2267            all keys (previously, the default TX key was configured as pairwise/
2268            unicast key)
2269          * driver_ndis: added legacy WPA capability detection for non-WPA2
2270            drivers
2271          * added support for setting static WEP keys for IEEE 802.1X without
2272            dynamic WEP keying (eapol_flags=0)
2273
22742004-12-12 - v0.3.1
2275          * added support for reading PKCS#12 (PFX) files (as a replacement for
2276            PEM/DER) to get certificate and private key (CONFIG_PKCS12)
2277          * fixed compilation with CONFIG_PCSC=y
2278          * added new ap_scan mode, ap_scan=2, for drivers that take care of
2279            association, but need to be configured with security policy and SSID,
2280            e.g., ndiswrapper and NDIS driver; this mode should allow such
2281            drivers to work with hidden SSIDs and optimized roaming; when
2282            ap_scan=2 is used, only the first network block in the configuration
2283            file is used and this configuration should have explicit security
2284            policy (i.e., only one option in the lists) for key_mgmt, pairwise,
2285            group, proto variables
2286          * added experimental port of wpa_supplicant for Windows
2287            - driver_ndis.c driver interface (NDIS OIDs)
2288            - currently, this requires cygwin and WinPcap
2289            - small utility, win_if_list, can be used to get interface name
2290          * control interface can now be removed at build time; add
2291            CONFIG_CTRL_IFACE=y to .config to maintain old functionality
2292          * optional Xsupplicant interface can now be removed at build time;
2293            (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
2294          * added auth_alg to driver interface associate() parameters to make it
2295            easier for drivers to configure authentication algorithm as part of
2296            the association
2297
22982004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
2299          * driver_broadcom: added new driver interface for Broadcom wl.o driver
2300            (a generic driver for Broadcom IEEE 802.11a/g cards)
2301          * wpa_cli: fixed parsing of -p <path> command line argument
2302          * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
2303            ACK, not tunneled EAP-Success (of which only the first byte was
2304            actually send due to a bug in previous code); this seems to
2305            interoperate with most RADIUS servers that implements PEAPv1
2306          * PEAPv1: added support for terminating PEAP authentication on tunneled
2307            EAP-Success message; this can be configured by adding
2308            peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
2309            (some RADIUS servers require this whereas others require a tunneled
2310            reply
2311          * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
2312            the old label for key derivation; previously, the default was 1,
2313            but it looks like most existing PEAPv1 implementations use the old
2314            label which is thus more suitable default option
2315          * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
2316          * fixed parsing of wep_tx_keyidx
2317          * added support for configuring list of allowed Phase 2 EAP types
2318            (for both EAP-PEAP and EAP-TTLS) instead of only one type
2319          * added support for configuring IEEE 802.11 authentication algorithm
2320            (auth_alg; mainly for using Shared Key authentication with static
2321            WEP keys)
2322          * added support for EAP-AKA (with UMTS SIM)
2323          * fixed couple of errors in PCSC handling that could have caused
2324            random-looking errors for EAP-SIM
2325          * added support for EAP-SIM pseudonyms and fast re-authentication
2326          * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
2327            session resumption)
2328          * added support for EAP-SIM with two challenges
2329            (phase1="sim_min_num_chal=3" can be used to require three challenges)
2330          * added support for configuring DH/DSA parameters for an ephemeral DH
2331            key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
2332            dh_file and dh_file2 (phase 2); this adds support for using DSA keys
2333            and optional DH key exchange to achieve forward secracy with RSA keys
2334          * added support for matching subject of the authentication server
2335            certificate with a substring when using EAP-TLS/PEAP/TTLS; new
2336            configuration variables subject_match and subject_match2
2337          * changed SSID configuration in driver_wext.c (used by many driver
2338            interfaces) to use ssid_len+1 as the length for SSID since some Linux
2339            drivers expect this
2340          * fixed couple of unaligned reads in scan result parsing to fix WPA
2341            connection on some platforms (e.g., ARM)
2342          * added driver interface for Intel ipw2100 driver
2343          * added support for LEAP with WPA
2344          * added support for larger scan results report (old limit was 4 kB of
2345            data, i.e., about 35 or so APs) when using Linux wireless extensions
2346            v17 or newer
2347          * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
2348            only if there is a PMKSA cache entry for the current AP
2349          * fixed error handling for case where reading of scan results fails:
2350            must schedule a new scan or wpa_supplicant will remain waiting
2351            forever
2352          * changed debug output to remove shared password/key material by
2353            default; all key information can be included with -K command line
2354            argument to match the previous behavior
2355          * added support for timestamping debug log messages (disabled by
2356            default, can be enabled with -t command line argument)
2357          * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
2358            if keys are not configured to be used; this fixes IEEE 802.1X mode
2359            with drivers that use this information to configure whether Privacy
2360            bit can be in Beacon frames (e.g., ndiswrapper)
2361          * avoid clearing driver keys if no keys have been configured since last
2362            key clear request; this seems to improve reliability of group key
2363            handshake for ndiswrapper & NDIS driver which seems to be suffering
2364            of some kind of timing issue when the keys are cleared again after
2365            association
2366          * changed driver interface API:
2367            - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
2368              version is being used (now, this is set to 2; previously, it was
2369              not defined)
2370            - pass pointer to private data structure to all calls
2371            - the new API is not backwards compatible; all in-tree driver
2372              interfaces has been converted to the new API
2373          * added support for controlling multiple interfaces (radios) per
2374            wpa_supplicant process; each interface needs to be listed on the
2375            command line (-c, -i, -D arguments) with -N as a separator
2376            (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
2377          * added a workaround for EAP servers that incorrectly use same Id for
2378            sequential EAP packets
2379          * changed libpcap/libdnet configuration to use .config variable,
2380            CONFIG_DNET_PCAP, instead of requiring Makefile modification
2381          * improved downgrade attack detection in IE verification of msg 3/4:
2382            verify both WPA and RSN IEs, if present, not only the selected one;
2383            reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
2384            Probe Response frame, and RSN is enabled in wpa_supplicant
2385            configuration
2386          * fixed WPA msg 3/4 processing to allow Key Data field contain other
2387            IEs than just one WPA IE
2388          * added support for FreeBSD and driver interface for the BSD net80211
2389            layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
2390            required kernel mods have not yet been committed
2391          * made EAP workarounds configurable; enabled by default, can be
2392            disabled with network block option eap_workaround=0
2393
23942004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
2395          * resolved couple of interoperability issues with EAP-PEAPv1 and
2396            Phase 2 (inner EAP) fragment reassembly
2397          * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
2398            AP is using non-zero key index for the unicast key and key index zero
2399            for the broadcast key
2400          * driver_hostap: fixed IEEE 802.1X WEP key updates and
2401            re-authentication by allowing unencrypted EAPOL frames when not using
2402            WPA
2403          * added a new driver interface, 'wext', which uses only standard,
2404            driver independent functionality in Linux wireless extensions;
2405            currently, this can be used only for non-WPA IEEE 802.1X mode, but
2406            eventually, this is to be extended to support full WPA/WPA2 once
2407            Linux wireless extensions get support for this
2408          * added support for mode in which the driver is responsible for AP
2409            scanning and selection; this is disabled by default and can be
2410            enabled with global ap_scan=0 variable in wpa_supplicant.conf;
2411            this mode can be used, e.g., with generic 'wext' driver interface to
2412            use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
2413            supporting wireless extensions.
2414          * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
2415            operation with an AP that does not include SSID in the Beacon frames)
2416          * added support for new EAP authentication methods:
2417            EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
2418          * added support for asking one-time-passwords from frontends (e.g.,
2419            wpa_cli); this 'otp' command works otherwise like 'password' command,
2420            but the password is used only once and the frontend will be asked for
2421            a new password whenever a request from authenticator requires a
2422            password; this can be used with both EAP-OTP and EAP-GTC
2423          * changed wpa_cli to automatically re-establish connection so that it
2424            does not need to be re-started when wpa_supplicant is terminated and
2425            started again
2426          * improved user data (identity/password/otp) requests through
2427            frontends: process pending EAPOL packets after getting new
2428            information so that full authentication does not need to be
2429            restarted; in addition, send pending requests again whenever a new
2430            frontend is attached
2431          * changed control frontends to use a new directory for socket files to
2432            make it easier for wpa_cli to automatically select between interfaces
2433            and to provide access control for the control interface;
2434            wpa_supplicant.conf: ctrl_interface is now a path
2435            (/var/run/wpa_supplicant is the recommended path) and
2436            ctrl_interface_group can be used to select which group gets access to
2437            the control interface;
2438            wpa_cli: by default, try to connect to the first interface available
2439            in /var/run/wpa_supplicant; this path can be overridden with -p option
2440            and an interface can be selected with -i option (i.e., in most common
2441            cases, wpa_cli does not need to get any arguments)
2442          * added support for LEAP
2443          * added driver interface for Linux ndiswrapper
2444          * added priority option for network blocks in the configuration file;
2445            this allows networks to be grouped based on priority (the scan
2446            results are searched for matches with network blocks in this order)
2447
24482004-06-20 - v0.2.3
2449          * sort scan results to improve AP selection
2450          * fixed control interface socket removal for some error cases
2451          * improved scan requesting and authentication timeout
2452          * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
2453            TLS processing
2454          * PEAP version can now be forced with phase1="peapver=<ver>"
2455            (mostly for testing; by default, the highest version supported by
2456            both the Supplicant and Authentication Server is selected
2457            automatically)
2458          * added support for madwifi driver (Atheros ar521x)
2459          * added a workaround for cases where AP sets Install Tx/Rx bit for
2460            WPA Group Key messages when pairwise keys are used (without this,
2461            the Group Key would be used for Tx and the AP would drop frames
2462            from the station)
2463          * added GSM SIM/USIM interface for GSM authentication algorithm for
2464            EAP-SIM; this requires pcsc-lite
2465          * added support for ATMEL AT76C5XXx driver
2466          * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
2467            does not include key data in the EAPOL-Key frame (i.e., part of
2468            EAP keying material is used as data encryption key)
2469          * added support for using plaintext and static WEP networks
2470            (key_mgmt=NONE)
2471
24722004-05-31 - v0.2.2
2473          * added support for new EAP authentication methods:
2474            EAP-TTLS/EAP-MD5-Challenge
2475            EAP-TTLS/EAP-GTC
2476            EAP-TTLS/EAP-MSCHAPv2
2477            EAP-TTLS/EAP-TLS
2478            EAP-TTLS/MSCHAPv2
2479            EAP-TTLS/MSCHAP
2480            EAP-TTLS/PAP
2481            EAP-TTLS/CHAP
2482            EAP-PEAP/TLS
2483            EAP-PEAP/GTC
2484            EAP-PEAP/MD5-Challenge
2485            EAP-GTC
2486            EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
2487          * added support for anonymous identity (to be used when identity is
2488            sent in plaintext; real identity will be used within TLS protected
2489            tunnel (e.g., with EAP-TTLS)
2490          * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
2491          * added support for requesting identity and password information using
2492            control interface; in other words, the password for EAP-PEAP or
2493            EAP-TTLS does not need to be included in the configuration file since
2494            a frontand (e.g., wpa_cli) can ask it from the user
2495          * improved RSN pre-authentication to use a candidate list and process
2496            all candidates from each scan; not only one per scan
2497          * fixed RSN IE and WPA IE capabilities field parsing
2498          * ignore Tx bit in GTK IE when Pairwise keys are used
2499          * avoid making new scan requests during IEEE 802.1X negotiation
2500          * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
2501            with TLS support (this replaces the included implementation with
2502            library code to save about 8 kB since the library code is needed
2503            anyway for TLS)
2504          * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
2505            (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
2506
25072004-05-06 - v0.2.1
2508          * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
2509            Supplicant
2510            - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
2511            - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
2512            - EAP-MD5 (cannot be used with WPA-RADIUS)
2513              [draft-ietf-eap-rfc2284bis-09.txt]
2514            - EAP-TLS [RFC 2716]
2515            - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
2516            - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
2517              [draft-kamath-pppext-eap-mschapv2-00.txt]
2518              (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
2519              default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
2520            - new configuration file options: eap, identity, password, ca_cert,
2521              client_cert, privatekey, private_key_passwd
2522            - Xsupplicant is not required anymore, but it can be used by
2523              disabling the internal IEEE 802.1X Supplicant with -e command line
2524              option
2525            - this code is not included in the default build; Makefile need to
2526              be edited for this (uncomment lines for selected functionality)
2527            - EAP-TLS and EAP-PEAP require openssl libraries
2528          * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
2529          * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
2530            (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
2531             EAPOL-Key frames instead of WPA key handshakes)
2532          * added support for IEEE 802.11i/RSN (WPA2)
2533            - improved PTK Key Handshake
2534            - PMKSA caching, pre-authentication
2535          * fixed wpa_supplicant to ignore possible extra data after WPA
2536            EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
2537            TPTK' error from message 3 of 4-Way Handshake in case the AP
2538            includes extra data after the EAPOL-Key)
2539          * added interface for external programs (frontends) to control
2540            wpa_supplicant
2541            - CLI example (wpa_cli) with interactive mode and command line
2542              mode
2543            - replaced SIGUSR1 status/statistics with the new control interface
2544          * made some feature compile time configurable
2545            - .config file for make
2546            - driver interfaces (hostap, hermes, ..)
2547            - EAPOL/EAP functions
