1022	  multiple PBKDF2 operations
1023	* added okc=1 global configuration parameter to allow OKC to be enabled
1024	  by default for all network blocks
1025	* added a workaround for WPS PBC session overlap detection to avoid
1026	  interop issues with deployed station implementations that do not
1027	  remove active PBC indication from Probe Request frames properly
1028	* added basic support for 60 GHz band
1029	* extend EAPOL frames processing workaround for roaming cases
1030	  (postpone processing of unexpected EAPOL frame until association
1031	  event to handle reordered events)
1032

1048	  config parameter ieee80211n.
1049	* Allow AP mode to disconnect STAs based on low ACK condition (when
1050	  the data connection is not working properly, e.g., due to the STA
1051	  going outside the range of the AP). Disabled by default, enable by
1052	  config option disassoc_low_ack.
1053	* nl80211:
1054	  - Support GTK rekey offload.
1055	  - Support PMKSA candidate events. This adds support for RSN

1071	    removing BSSs.
1072	  - Treat '' in SSIDs of Interface.Scan as a request for broadcast
1073	    scan, instead of ignoring it.
1074	  - Add DBus getter/setter for FastReauth.
1075	  - Raise PropertiesChanged on org.freedesktop.DBus.Properties.
1076	* wpa_cli:
1077	  - Send AP-STA-DISCONNECTED event when an AP disconnects a station
1078	    due to inactivity.
1079	  - Make second argument to set command optional. This can be used to
1080	    indicate a zero length value.
1081	  - Add signal_poll command.
1082	  - Add bss_expire_age and bss_expire_count commands to set/get BSS
1083	    cache expiration age and expiration scan count.
1084	  - Add ability to set scan interval (the time in seconds wpa_s waits
1085	    before requesting a new scan after failing to find a suitable
1086	    network in scan results) using scan_interval command.
1087	  - Add event CTRL-EVENT-ASSOC-REJECT for association rejected.
1088	  - Add command get version, that returns wpa_supplicant version string.
1089	  - Add command sta_autoconnect for disabling automatic reconnection
1090	    on receiving disconnection event.

1093	    bssid filtering.
1094	  - Add tdls_testing command to add a special testing feature for
1095	    changing TDLS behavior. Build param CONFIG_TDLS_TESTING must be
1096	    enabled as well.
1097	  - For interworking, add wpa_cli commands interworking_select,
1098	    interworking_connect, anqp_get, fetch_anqp, and stop_fetch_anqp.

1105	    log.
1106	  - Add internal line edit implementation. CONFIG_WPA_CLI_EDIT=y
1107	    can now be used to build wpa_cli with internal implementation of
1108	    line editing and history support. This can be used as a replacement
1109	    for CONFIG_READLINE=y.

1116	  manage the BSS blacklist and display its current contents.
1117	* WPS:
1118	  - Add wpa_cli wps_pin get command for generating random PINs. This can
1119	    be used in a UI to generate a PIN without starting WPS (or P2P)
1120	    operation.
1121	  - Set RF bands based on driver capabilities, instead of hardcoding
1122	    them.

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

1167	  - Add support for AuthorizedMACs attribute.
1168	* TDLS:
1169	  - Propagate TDLS related nl80211 capability flags from kernel and
1170	    add them as driver capability flags. If the driver doesn't support
1171	    capabilities, assume TDLS is supported internally. When TDLS is
1172	    explicitly not supported, disable all user facing TDLS operations.
1173	  - Allow TDLS to be disabled at runtime (mostly for testing).
1174	    Use set tdls_disabled.
1175	  - Honor AP TDLS settings that prohibit/allow TDLS.
1176	  - Add a special testing feature for changing TDLS behavior. Use

1186	  interworking_select, interworking_connect, anqp_get, fetch_anqp,
1187	  and stop_fetch_anqp.
1188	* Android: Add build and runtime support for Android wpa_supplicant.
1189	* bgscan learn: Add new bgscan that learns BSS information based on
1190	  previous scans, and uses that information to dynamically generate
1191	  the list of channels for background scans.

1206
12072010-04-18 - v0.7.2
1208	* nl80211: fixed number of issues with roaming
1209	* avoid unnecessary roaming if multiple APs with similar signal
1210	  strength are present in scan results
1211	* add TLS client events and server probing to ease design of
1212	  automatic detection of EAP parameters
1213	* add option for server certificate matching (SHA256 hash of the
1214	  certificate) instead of trusted CA certificate configuration
1215	* bsd: Cleaned up driver wrapper and added various low-level
1216	  configuration options
1217	* wpa_gui-qt4: do not show too frequent WPS AP available events as
1218	  tray messages
1219	* TNC: fixed issues with fragmentation
1220	* EAP-TNC: add Flags field into fragment acknowledgement (needed to
1221	  interoperate with other implementations; may potentially breaks
1222	  compatibility with older wpa_supplicant/hostapd versions)
1223	* wpa_cli: added option for using a separate process to receive event
1224	  messages to reduce latency in showing these
1225	  (CFLAGS += -DCONFIG_WPA_CLI_FORK=y in .config to enable this)
1226	* maximum BSS table size can now be configured (bss_max_count)
1227	* BSSes to be included in the BSS table can be filtered based on
1228	  configured SSIDs to save memory (filter_ssids)
1229	* fix number of issues with IEEE 802.11r/FT; this version is not
1230	  backwards compatible with old versions
1231	* nl80211: add support for IEEE 802.11r/FT protocol (both over-the-air
1232	  and over-the-DS)
1233	* add freq_list network configuration parameter to allow the AP
1234	  selection to filter out entries based on the operating channel
1235	* add signal strength change events for bgscan; this allows more
1236	  dynamic changes to background scanning interval based on changes in
1237	  the signal strength with the current AP; this improves roaming within
1238	  ESS quite a bit, e.g., with bgscan="simple:30:-45:300" in the network
1239	  configuration block to request background scans less frequently when
1240	  signal strength remains good and to automatically trigger background
1241	  scans whenever signal strength drops noticeably
1242	  (this is currently only available with nl80211)
1243	* add BSSID and reason code (if available) to disconnect event messages
1244	* wpa_gui-qt4: more complete support for translating the GUI with
1245	  linguist and add German translation
1246	* fix DH padding with internal crypto code (mainly, for WPS)
1247	* do not trigger initial scan automatically anymore if there are no
1248	  enabled networks
1249
12502010-01-16 - v0.7.1
1251	* cleaned up driver wrapper API (struct wpa_driver_ops); the new API
1252	  is not fully backwards compatible, so out-of-tree driver wrappers
1253	  will need modifications
1254	* cleaned up various module interfaces
1255	* merge hostapd and wpa_supplicant developers' documentation into a
1256	  single document
1257	* nl80211: use explicit deauthentication to clear cfg80211 state to
1258	  avoid issues when roaming between APs
1259	* dbus: major design changes in the new D-Bus API
1260	  (fi.w1.wpa_supplicant1)
1261	* nl80211: added support for IBSS networks
1262	* added internal debugging mechanism with backtrace support and memory
1263	  allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y)
1264	* added WPS ER unsubscription command to more cleanly unregister from
1265	  receiving UPnP events when ER is terminated
1266	* cleaned up AP mode operations to avoid need for virtual driver_ops
1267	  wrapper
1268	* added BSS table to maintain more complete scan result information
1269	  over multiple scans (that may include only partial results)
1270	* wpa_gui-qt4: update Peers dialog information more dynamically while
1271	  the dialog is kept open
1272	* fixed PKCS#12 use with OpenSSL 1.0.0
1273	* driver_wext: Added cfg80211-specific optimization to avoid some
1274	  unnecessary scans and to speed up association
1275
12762009-11-21 - v0.7.0
1277	* increased wpa_cli ping interval to 5 seconds and made this
1278	  configurable with a new command line options (-G<seconds>)
1279	* fixed scan buffer processing with WEXT to handle up to 65535
1280	  byte result buffer (previously, limited to 32768 bytes)
1281	* allow multiple driver wrappers to be specified on command line
1282	  (e.g., -Dnl80211,wext); the first one that is able to initialize the
1283	  interface will be used
1284	* added support for multiple SSIDs per scan request to optimize
1285	  scan_ssid=1 operations in ap_scan=1 mode (i.e., search for hidden
1286	  SSIDs); this requires driver support and can currently be used only
1287	  with nl80211
1288	* added support for WPS USBA out-of-band mechanism with USB Flash
1289	  Drives (UFD) (CONFIG_WPS_UFD=y)
1290	* driver_ndis: add PAE group address to the multicast address list to
1291	  fix wired IEEE 802.1X authentication
1292	* fixed IEEE 802.11r key derivation function to match with the standard
1293	  (note: this breaks interoperability with previous version) [Bug 303]
1294	* added better support for drivers that allow separate authentication
1295	  and association commands (e.g., mac80211-based Linux drivers with
1296	  nl80211; SME in wpa_supplicant); this allows over-the-air FT protocol
1297	  to be used (IEEE 802.11r)
1298	* fixed SHA-256 based key derivation function to match with the
1299	  standard when using CCMP (for IEEE 802.11r and IEEE 802.11w)
1300	  (note: this breaks interoperability with previous version) [Bug 307]
1301	* use shared driver wrapper files with hostapd
1302	* added AP mode functionality (CONFIG_AP=y) with mode=2 in the network
1303	  block; this can be used for open and WPA2-Personal networks
1304	  (optionally, with WPS); this links in parts of hostapd functionality
1305	  into wpa_supplicant
1306	* wpa_gui-qt4: added new Peers dialog to show information about peers
1307	  (other devices, including APs and stations, etc. in the neighborhood)
1308	* added support for WPS External Registrar functionality (configure APs
1309	  and enroll new devices); can be used with wpa_gui-qt4 Peers dialog
1310	  and wpa_cli commands wps_er_start, wps_er_stop, wps_er_pin,
1311	  wps_er_pbc, wps_er_learn
1312	  (this can also be used with a new 'none' driver wrapper if no
1313	  wireless device or IEEE 802.1X on wired is needed)
1314	* driver_nl80211: multiple updates to provide support for new Linux
1315	  nl80211/mac80211 functionality
1316	* updated management frame protection to use IEEE Std 802.11w-2009
1317	* fixed number of small WPS issues and added workarounds to
1318	  interoperate with common deployed broken implementations
1319	* added support for NFC out-of-band mechanism with WPS
1320	* driver_ndis: fixed wired IEEE 802.1X authentication with PAE group
1321	  address frames
1322	* added preliminary support for IEEE 802.11r RIC processing
1323	* added support for specifying subset of enabled frequencies to scan
1324	  (scan_freq option in the network configuration block); this can speed
1325	  up scanning process considerably if it is known that only a small
1326	  subset of channels is actually used in the network (this is currently
1327	  supported only with -Dnl80211)
1328	* added a workaround for race condition between receiving the
1329	  association event and the following EAPOL-Key
1330	* added background scan and roaming infrastructure to allow
1331	  network-specific optimizations to be used to improve roaming within
1332	  an ESS (same SSID)
1333	* added new DBus interface (fi.w1.wpa_supplicant1)
1334
13352009-01-06 - v0.6.7
1336	* added support for Wi-Fi Protected Setup (WPS)
1337	  (wpa_supplicant can now be configured to act as a WPS Enrollee to
1338	  enroll credentials for a network using PIN and PBC methods; in
1339	  addition, wpa_supplicant can act as a wireless WPS Registrar to
1340	  configure an AP); WPS support can be enabled by adding CONFIG_WPS=y
1341	  into .config and setting the runtime configuration variables in
1342	  wpa_supplicant.conf (see WPS section in the example configuration
1343	  file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to
1344	  manage WPS negotiation; see README-WPS for more details
1345	* added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
1346	* added support for using driver_test over UDP socket
1347	* fixed PEAPv0 Cryptobinding interoperability issue with Windows Server
1348	  2008 NPS; optional cryptobinding is now enabled (again) by default
1349	* fixed PSK editing in wpa_gui
1350	* changed EAP-GPSK to use the IANA assigned EAP method type 51
1351	* added a Windows installer that includes WinPcap and all the needed
1352	  DLLs; in addition, it set up the registry automatically so that user
1353	  will only need start wpa_gui to get prompted to start the wpasvc
1354	  servide and add a new interface if needed through wpa_gui dialog
1355	* updated management frame protection to use IEEE 802.11w/D7.0
1356
13572008-11-23 - v0.6.6
1358	* added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
1359	  (can be used to simulate test SIM/USIM card with a known private key;
1360	  enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
1361	  and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
1362	* added a new network configuration option, wpa_ptk_rekey, that can be
1363	  used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
1364	  against TKIP deficiencies
1365	* added an optional mitigation mechanism for certain attacks against
1366	  TKIP by delaying Michael MIC error reports by a random amount of time
1367	  between 0 and 60 seconds; this can be enabled with a build option
1368	  CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
1369	* fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
1370	  not bytes
1371	* updated OpenSSL code for EAP-FAST to use an updated version of the
1372	  session ticket overriding API that was included into the upstream
1373	  OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
1374	  needed with that version anymore)
1375	* updated userspace MLME instructions to match with the current Linux
1376	  mac80211 implementation; please also note that this can only be used
1377	  with driver_nl80211.c (the old code from driver_wext.c was removed)
1378	* added support (Linux only) for RoboSwitch chipsets (often found in
1379	  consumer grade routers); driver interface 'roboswitch'
1380	* fixed canceling of PMKSA caching when using drivers that generate
1381	  RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
1382	  about
1383
13842008-11-01 - v0.6.5
1385	* added support for SHA-256 as X.509 certificate digest when using the
1386	  internal X.509/TLSv1 implementation
1387	* updated management frame protection to use IEEE 802.11w/D6.0
1388	* added support for using SHA256-based stronger key derivation for WPA2
1389	  (IEEE 802.11w)
1390	* fixed FT (IEEE 802.11r) authentication after a failed association to
1391	  use correct FTIE
1392	* added support for configuring Phase 2 (inner/tunneled) authentication
1393	  method with wpa_gui-qt4
1394
13952008-08-10 - v0.6.4
1396	* added support for EAP Sequences in EAP-FAST Phase 2
1397	* added support for using TNC with EAP-FAST
1398	* added driver_ps3 for the PS3 Linux wireless driver
1399	* added support for optional cryptobinding with PEAPv0
1400	* fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
1401	  allow fallback to full handshake if server rejects PAC-Opaque
1402	* added fragmentation support for EAP-TNC
1403	* added support for parsing PKCS #8 formatted private keys into the
1404	  internal TLS implementation (both PKCS #1 RSA key and PKCS #8
1405	  encapsulated RSA key can now be used)
1406	* added option of using faster, but larger, routines in the internal
1407	  LibTomMath (for internal TLS implementation) to speed up DH and RSA
1408	  calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
1409	* fixed race condition between disassociation event and group key
1410	  handshake to avoid getting stuck in incorrect state [Bug 261]
1411	* fixed opportunistic key caching (proactive_key_caching)
1412
14132008-02-22 - v0.6.3
1414	* removed 'nai' and 'eappsk' network configuration variables that were
1415	  previously used for configuring user identity and key for EAP-PSK,
1416	  EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
1417	  replacement for 'nai' (if old configuration used a separate
1418	  'identity' value, that would now be configured as
1419	  'anonymous_identity'). 'password' field is now used as the
1420	  replacement for 'eappsk' (it can also be set using hexstring to
1421	  present random binary data)
1422	* removed '-w' command line parameter (wait for interface to be added,
1423	  if needed); cleaner way of handling this functionality is to use an
1424	  external mechanism (e.g., hotplug scripts) that start wpa_supplicant
1425	  when an interface is added
1426	* updated FT support to use the latest draft, IEEE 802.11r/D9.0
1427	* added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
1428	  indicating when new scan results become available
1429	* added new ctrl_iface command, BSS, to allow scan results to be
1430	  fetched without hitting the message size limits (this command
1431	  can be used to iterate through the scan results one BSS at the time)
1432	* fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
1433	  attributes in EAP-SIM Start/Response when using fast reauthentication
1434	* fixed EAPOL not to end up in infinite loop when processing dynamic
1435	  WEP keys with IEEE 802.1X
1436	* fixed problems in getting NDIS events from WMI on Windows 2000
1437
14382008-01-01 - v0.6.2
1439	* added support for Makefile builds to include debug-log-to-a-file
1440	  functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
1441	* fixed EAP-SIM and EAP-AKA message parser to validate attribute
1442	  lengths properly to avoid potential crash caused by invalid messages
1443	* added data structure for storing allocated buffers (struct wpabuf);
1444	  this does not affect wpa_supplicant usage, but many of the APIs
1445	  changed and various interfaces (e.g., EAP) is not compatible with old
1446	  versions
1447	* added support for protecting EAP-AKA/Identity messages with
1448	  AT_CHECKCODE (optional feature in RFC 4187)
1449	* added support for protected result indication with AT_RESULT_IND for
1450	  EAP-SIM and EAP-AKA (phase1="result_ind=1")
1451	* added driver_wext workaround for race condition between scanning and
1452	  association with drivers that take very long time to scan all
1453	  channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
1454	  using a longer hardcoded timeout for the scan if the driver supports
1455	  notifications for scan completion (SIOCGIWSCAN event); this helps,
1456	  e.g., in cases where wpa_supplicant and madwifi driver ended up in
1457	  loop where the driver did not even try to associate
1458	* stop EAPOL timer tick when no timers are in use in order to reduce
1459	  power consumption (no need to wake up the process once per second)
1460	  [Bug 237]
1461	* added support for privilege separation (run only minimal part of
1462	  wpa_supplicant functionality as root and rest as unprivileged,
1463	  non-root process); see 'Privilege separation' in README for details;
1464	  this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
1465	  in .config
1466	* changed scan results data structure to include all information
1467	  elements to make it easier to support new IEs; old get_scan_result()
1468	  driver_ops is still supported for backwards compatibility (results
1469	  are converted internally to the new format), but all drivers should
1470	  start using the new get_scan_results2() to make them more likely to
1471	  work with new features
1472	* Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
1473	  application, i.e., it does not require Qt3Support anymore; Windows
1474	  binary of wpa_gui.exe is now from this directory and only requires
1475	  QtCore4.dll and QtGui4.dll libraries
1476	* updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
1477	  available as a separate package to make wpa_gui installation easier:
1478	  http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
1479	* added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
1480	  only shared key/password authentication is supported in this version
1481
14822007-11-24 - v0.6.1
1483	* added support for configuring password as NtPasswordHash
1484	  (16-byte MD4 hash of password) in hash:<32 hex digits> format
1485	* added support for fallback from abbreviated TLS handshake to
1486	  full handshake when using EAP-FAST (e.g., due to an expired
1487	  PAC-Opaque)
1488	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
1489	  draft (draft-ietf-emu-eap-gpsk-07.txt)
1490	* added support for drivers that take care of RSN 4-way handshake
1491	  internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
1492	  WPA_ALG_PMK in set_key)
1493	* added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
1494	  .config); this version supports only ap_scan=2 mode and allow the
1495	  driver to take care of the 4-way handshake
1496	* fixed a buffer overflow in parsing TSF from scan results when using
1497	  driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
1498	  [Bug 232]
1499	* updated FT support to use the latest draft, IEEE 802.11r/D8.0
1500	* fixed an integer overflow issue in the ASN.1 parser used by the
1501	  (experimental) internal TLS implementation to avoid a potential
1502	  buffer read overflow
1503	* fixed a race condition with -W option (wait for a control interface
1504	  monitor before starting) that could have caused the first messages to
1505	  be lost
1506	* added support for processing TNCC-TNCS-Messages to report
1507	  recommendation (allow/none/isolate) when using TNC [Bug 243]
1508
15092007-05-28 - v0.6.0
1510	* added network configuration parameter 'frequency' for setting
1511	  initial channel for IBSS (adhoc) networks
1512	* added experimental IEEE 802.11r/D6.0 support
1513	* updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
1514	* updated EAP-PSK to use the IANA-allocated EAP type 47
1515	* fixed EAP-PAX key derivation
1516	* fixed EAP-PSK bit ordering of the Flags field
1517	* fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
1518	  tunnelled identity request (previously, the identifier from the outer
1519	  method was used, not the tunnelled identifier which could be
1520	  different)
1521	* added support for fragmentation of outer TLS packets during Phase 2
1522	  of EAP-PEAP/TTLS/FAST
1523	* fixed EAP-TTLS AVP parser processing for too short AVP lengths
1524	* added support for EAP-FAST authentication with inner methods that
1525	  generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
1526	  for PAC provisioning)
1527	* added support for authenticated EAP-FAST provisioning
1528	* added support for configuring maximum number of EAP-FAST PACs to
1529	  store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
1530	* added support for storing EAP-FAST PACs in binary format
1531	  (fast_pac_format=binary in phase1 string)
1532	* fixed dbus ctrl_iface to validate message interface before
1533	  dispatching to avoid a possible segfault [Bug 190]
1534	* fixed PeerKey key derivation to use the correct PRF label
1535	* updated Windows binary build to link against OpenSSL 0.9.8d and
1536	  added support for EAP-FAST
1537	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
1538	  draft (draft-ietf-emu-eap-gpsk-04.txt)
1539	* fixed EAP-AKA Notification processing to allow Notification to be
1540	  processed after AKA Challenge response has been sent
1541	* updated to use IEEE 802.11w/D2.0 for management frame protection
1542	  (still experimental)
1543	* fixed EAP-TTLS implementation not to crash on use of freed memory
1544	  if TLS library initialization fails
1545	* added support for EAP-TNC (Trusted Network Connect)
1546	  (this version implements the EAP-TNC method and EAP-TTLS changes
1547	  needed to run two methods in sequence (IF-T) and the IF-IMC and
1548	  IF-TNCCS interfaces from TNCC)
1549
15502006-11-24 - v0.5.6
1551	* added experimental, integrated TLSv1 client implementation with the
1552	  needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
1553	  setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
1554	  .config); this can be useful, e.g., if the target system does not
1555	  have a suitable TLS library and a minimal code size is required
1556	  (total size of this internal TLS/crypto code is bit under 50 kB on
1557	  x86 and the crypto code is shared by rest of the supplicant so some
1558	  of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
1559	* removed STAKey handshake since PeerKey handshake has replaced it in
1560	  IEEE 802.11ma and there are no known deployments of STAKey
1561	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
1562	  draft (draft-ietf-emu-eap-gpsk-01.txt)
1563	* added preliminary implementation of IEEE 802.11w/D1.0 (management
1564	  frame protection)
1565	  (Note: this requires driver support to work properly.)
1566	  (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
1567	* fixed Windows named pipes ctrl_iface to not stop listening for
1568	  commands if client program opens a named pipe and closes it
1569	  immediately without sending a command
1570	* fixed USIM PIN status determination for the case that PIN is not
1571	  needed (this allows EAP-AKA to be used with USIM cards that do not
1572	  use PIN)
1573	* added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
1574	  be used with cards that do not support file selection based on
1575	  partial AID
1576	* added support for matching the subjectAltName of the authentication
1577	  server certificate against multiple name components (e.g.,
1578	  altsubject_match="DNS:server.example.com;DNS:server2.example.com")
1579	* fixed EAP-SIM/AKA key derivation for re-authentication case (only
1580	  affects IEEE 802.1X with dynamic WEP keys)
1581	* changed ctrl_iface network configuration 'get' operations to not
1582	  return password/key material; if these fields are requested, "*"
1583	  will be returned if the password/key is set, but the value of the
1584	  parameter is not exposed
1585
15862006-08-27 - v0.5.5
1587	* added support for building Windows version with UNICODE defined
1588	  (wide-char functions)
1589	* driver_ndis: fixed static WEP configuration to avoid race condition
1590	  issues with some NDIS drivers between association and setting WEP
1591	  keys
1592	* driver_ndis: added validation for IELength value in scan results to
1593	  avoid crashes when using buggy NDIS drivers [Bug 165]
1594	* fixed Release|Win32 target in the Visual Studio project files
1595	  (previously, only Debug|Win32 target was set properly)
1596	* changed control interface API call wpa_ctrl_pending() to allow it to
1597	  return -1 on error (e.g., connection lost); control interface clients
1598	  will need to make sure that they verify that the value is indeed >0
1599	  when determining whether there are pending messages
1600	* added an alternative control interface backend for Windows targets:
1601	  Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
1602	  control interface mechanism for Windows builds (previously, UDP to
1603	  localhost was used)
1604	* changed ctrl_interface configuration for UNIX domain sockets:
1605	  - deprecated ctrl_interface_group variable (it may be removed in
1606	    future versions)
1607	  - allow both directory and group be configured with ctrl_interface
1608	    in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
1609	  - ctrl_interface=/var/run/wpa_supplicant is still supported for the
1610	    case when group is not changed
1611	* added support for controlling more than one interface per process in
1612	  Windows version
1613	* added a workaround for a case where the AP is using unknown address
1614	  (e.g., MAC address of the wired interface) as the source address for
1615	  EAPOL-Key frames; previously, that source address was used as the
1616	  destination for EAPOL-Key frames and in key derivation; now, BSSID is
1617	  used even if the source address does not match with it
1618	  (this resolves an interoperability issue with Thomson SpeedTouch 580)
1619	* added a workaround for UDP-based control interface (which was used in
1620	  Windows builds before this release) to prevent packets with forged
1621	  addresses from being accepted as local control requests
1622	* removed ndis_events.cpp and possibility of using external
1623	  ndis_events.exe; C version (ndis_events.c) is fully functional and
1624	  there is no desire to maintain two separate versions of this
1625	  implementation
1626	* ndis_events: Changed NDIS event notification design to use WMI to
1627	  learn the adapter description through Win32_PnPEntity class; this
1628	  should fix some cases where the adapter name was not recognized
1629	  correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
1630	  USB) [Bug 113]
1631	* fixed selection of the first network in ap_scan=2 mode; previously,
1632	  wpa_supplicant could get stuck in SCANNING state when only the first
1633	  network for enabled (e.g., after 'wpa_cli select_network 0')
1634	* winsvc: added support for configuring ctrl_interface parameters in
1635	  registry (ctrl_interface string value in
1636	  HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
1637	  required to enable control interface (previously, this was hardcoded
1638	  to be enabled)
1639	* allow wpa_gui subdirectory to be built with both Qt3 and Qt4
1640	* converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
1641
16422006-06-20 - v0.5.4
1643	* fixed build with CONFIG_STAKEY=y [Bug 143]
1644	* added support for doing MLME (IEEE 802.11 management frame
1645	  processing) in wpa_supplicant when using Devicescape IEEE 802.11
1646	  stack (wireless-dev.git tree)
1647	* added a new network block configuration option, fragment_size, to
1648	  configure the maximum EAP fragment size
1649	* driver_ndis: Disable WZC automatically for the selected interface to
1650	  avoid conflicts with two programs trying to control the radio; WZC
1651	  will be re-enabled (if it was enabled originally) when wpa_supplicant
1652	  is terminated
1653	* added an experimental TLSv1 client implementation
1654	  (CONFIG_TLS=internal) that can be used instead of an external TLS
1655	  library, e.g., to reduce total size requirement on systems that do
1656	  not include any TLS library by default (this is not yet complete;
1657	  basic functionality is there, but certificate validation is not yet
1658	  included)
1659	* added PeerKey handshake implementation for IEEE 802.11e
1660	  direct link setup (DLS) to replace STAKey handshake
1661	* fixed WPA PSK update through ctrl_iface for the case where the old
1662	  PSK was derived from an ASCII passphrase and the new PSK is set as
1663	  a raw PSK (hex string)
1664	* added new configuration option for identifying which network block
1665	  was used (id_str in wpa_supplicant.conf; included on
1666	  WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
1667	  variable in wpa_cli action scripts; in addition WPA_ID variable is
1668	  set to the current unique identifier that wpa_supplicant assigned
1669	  automatically for the network and that can be used with
1670	  GET_NETWORK/SET_NETWORK ctrl_iface commands)
1671	* wpa_cli action script is now called only when the connect/disconnect
1672	  status changes or when associating with a different network
1673	* fixed configuration parser not to remove CCMP from group cipher list
1674	  if WPA-None (adhoc) is used (pairwise=NONE in that case)
1675	* fixed integrated NDIS events processing not to hang the process due
1676	  to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
1677	* added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
1678	  draft-clancy-emu-eap-shared-secret-00.txt)
1679	* added Microsoft Visual Studio 2005 solution and project files for
1680	  build wpa_supplicant for Windows (see vs2005 subdirectory)
1681	* eloop_win: fixed unregistration of Windows events
1682	* l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
1683	  at the end of RSN pre-authentication and added unregistration of
1684	  a Windows event to avoid getting eloop_win stuck with an invalid
1685	  handle
1686	* driver_ndis: added support for selecting AP based on BSSID
1687	* added new environmental variable for wpa_cli action scripts:
1688	  WPA_CTRL_DIR is the current control interface directory
1689	* driver_ndis: added support for using NDISUIO instead of WinPcap for
1690	  OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
1691	  l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
1692	  wpa_supplicant without requiring WinPcap; note that using NDISUIO
1693	  requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
1694	  only one application to open the device
1695	* changed NDIS driver naming to only include device GUID, e.g.,
1696	  {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
1697	  specific \Device\NPF_ prefix before the GUID; the prefix is still
1698	  allowed for backwards compatibility, but it is not required anymore
1699	  when specifying the interface
1700	* driver_ndis: re-initialize driver interface is the adapter is removed
1701	  and re-inserted [Bug 159]
1702	* driver_madwifi: fixed TKIP and CCMP sequence number configuration on
1703	  big endian hosts [Bug 146]
1704
17052006-04-27 - v0.5.3
1706	* fixed EAP-GTC response to include correct user identity when run as
1707	  phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
1708	* driver_ndis: Fixed encryption mode configuration for unencrypted
1709	  networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
1710	  refused to associate with open networks) [Bug 106]
1711	* driver_ndis: use BSSID OID polling to detect when IBSS network is
1712	  formed even when ndis_events code is included since some NDIS drivers
1713	  do not generate media connect events in IBSS mode
1714	* config_winreg: allow global ctrl_interface parameter to be configured
1715	  in Windows registry
1716	* config_winreg: added support for saving configuration data into
1717	  Windows registry
1718	* added support for controlling network device operational state
1719	  (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
1720	  http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
1721	  that can use this information)
1722	* driver_wext: added support for WE-21 change to SSID configuration
1723	* driver_wext: fixed privacy configuration for static WEP keys mode
1724	  [Bug 140]
1725	* added an optional driver_ops callback for MLME-SETPROTECTION.request
1726	  primitive
1727	* added support for EAP-SAKE (no EAP method number allocated yet, so
1728	  this is using the same experimental type 255 as EAP-PSK)
1729	* added support for dynamically loading EAP methods (.so files) instead
1730	  of requiring them to be statically linked in; this is disabled by
1731	  default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
1732	  on how to use this)
1733
17342006-03-19 - v0.5.2
1735	* do not try to use USIM APDUs when initializing PC/SC for SIM card
1736	  access for a network that has not enabled EAP-AKA
1737	* fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
1738	  v0.5.1 due to the new support for expanded EAP types)
1739	* added support for generating EAP Expanded Nak
1740	* try to fetch scan results once before requesting new scan when
1741	  starting up in ap_scan=1 mode (this can speed up initial association
1742	  a lot with, e.g., madwifi-ng driver)
1743	* added support for receiving EAPOL frames from a Linux bridge
1744	  interface (-bbr0 on command line)
1745	* fixed EAPOL re-authentication for sessions that used PMKSA caching
1746	* changed EAP method registration to use a dynamic list of methods
1747	  instead of a static list generated at build time
1748	* fixed PMKSA cache deinitialization not to use freed memory when
1749	  removing PMKSA entries
1750	* fixed a memory leak in EAP-TTLS re-authentication
1751	* reject WPA/WPA2 message 3/4 if it does not include any valid
1752	  WPA/RSN IE
1753	* driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
1754	  if the driver does not support SIOCSIWAUTH
1755
17562006-01-29 - v0.5.1
1757	* driver_test: added better support for multiple APs and STAs by using
1758	  a directory with sockets that include MAC address for each device in
1759	  the name (driver_param=test_dir=/tmp/test)
1760	* added support for EAP expanded type (vendor specific EAP methods)
1761	* added AP_SCAN command into ctrl_iface so that ap_scan configuration
1762	  option can be changed if needed
1763	* wpa_cli/wpa_gui: skip non-socket files in control directory when
1764	  using UNIX domain sockets; this avoids selecting an incorrect
1765	  interface (e.g., a PID file could be in this directory, even though
1766	  use of this directory for something else than socket files is not
1767	  recommended)
1768	* fixed TLS library deinitialization after RSN pre-authentication not
1769	  to disable TLS library for normal authentication
1770	* driver_wext: Remove null-termination from SSID length if the driver
1771	  used it; some Linux drivers do this and they were causing problems in
1772	  wpa_supplicant not finding matching configuration block. This change
1773	  would break a case where the SSID actually ends in '\0', but that is
1774	  not likely to happen in real use.
1775	* fixed PMKSA cache processing not to trigger deauthentication if the
1776	  current PMKSA cache entry is replaced with a valid new entry
1777	* fixed PC/SC initialization for ap_scan != 1 modes (this fixes
1778	  EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
1779	  ap_scan=2)
1780
17812005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
1782	* added experimental STAKey handshake implementation for IEEE 802.11e
1783	  direct link setup (DLS); note: this is disabled by default in both
1784	  build and runtime configuration (can be enabled with CONFIG_STAKEY=y
1785	  and stakey=1)
1786	* fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
1787	  decrypt AT_ENCR_DATA attributes correctly
1788	* fixed EAP-AKA to allow resynchronization within the same session
1789	* made code closer to ANSI C89 standard to make it easier to port to
1790	  other C libraries and compilers
1791	* started moving operating system or C library specific functions into
1792	  wrapper functions defined in os.h and implemented in os_*.c to make
1793	  code more portable
1794	* wpa_supplicant can now be built with Microsoft Visual C++
1795	  (e.g., with the freely available Toolkit 2003 version or Visual
1796	  C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
1797	  example makefile for nmake
1798	* added support for using Windows registry for command line parameters
1799	  (CONFIG_MAIN=main_winsvc) and configuration data
1800	  (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
1801	  contents; this version can be run both as a Windows service and as a
1802	  normal application; 'wpasvc.exe app' to start as applicant,
1803	  'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
1804	  'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
1805	  unregister a service
1806	* made it possible to link ndis_events.exe functionality into
1807	  wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
1808	* added better support for multiple control interface backends
1809	  (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
1810	* fixed PC/SC code to use correct length for GSM AUTH command buffer
1811	  and to not use pioRecvPci with SCardTransmit() calls; these were not
1812	  causing visible problems with pcsc-lite, but Windows Winscard.dll
1813	  refused the previously used parameters; this fixes EAP-SIM and
1814	  EAP-AKA authentication using SIM/USIM card under Windows
1815	* added new event loop implementation for Windows using
1816	  WaitForMultipleObject() instead of select() in order to allow waiting
1817	  for non-socket objects; this can be selected with
1818	  CONFIG_ELOOP=eloop_win in .config
1819	* added support for selecting l2_packet implementation in .config
1820	  (CONFIG_L2_PACKET; following options are available now: linux, pcap,
1821	  winpcap, freebsd, none)
1822	* added new l2_packet implementation for WinPcap
1823	  (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
1824	  reduce latency in EAPOL receive processing from about 100 ms to about
1825	  3 ms
1826	* added support for EAP-FAST key derivation using other ciphers than
1827	  RC4-128-SHA for authentication and AES128-SHA for provisioning
1828	* added support for configuring CA certificate as DER file and as a
1829	  configuration blob
1830	* fixed private key configuration as configuration blob and added
1831	  support for using PKCS#12 as a blob
1832	* tls_gnutls: added support for using PKCS#12 files; added support for
1833	  session resumption
1834	* added support for loading trusted CA certificates from Windows
1835	  certificate store: ca_cert="cert_store://<name>", where <name> is
1836	  likely CA (Intermediate CA certificates) or ROOT (root certificates)
1837	* added C version of ndis_events.cpp and made it possible to build this
1838	  with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
1839	  easily on cross-compilation builds
1840	* added wpasvc.exe into Windows binary release; this is an alternative
1841	  version of wpa_supplicant.exe with configuration backend using
1842	  Windows registry and with the entry point designed to run as a
1843	  Windows service
1844	* integrated ndis_events.exe functionality into wpa_supplicant.exe and
1845	  wpasvc.exe and removed this additional tool from the Windows binary
1846	  release since it is not needed anymore
1847	* load winscard.dll functions dynamically when building with MinGW
1848	  since MinGW does not yet include winscard library
1849
18502005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
1851	* l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
1852	  and WinPcap to receive frames sent to PAE group address
1853	* disable EAP state machine when IEEE 802.1X authentication is not used
1854	  in order to get rid of bogus "EAP failed" messages
1855	* fixed OpenSSL error reporting to go through all pending errors to
1856	  avoid confusing reports of old errors being reported at later point
1857	  during handshake
1858	* fixed configuration file updating to not write empty variables
1859	  (e.g., proto or key_mgmt) that the file parser would not accept
1860	* fixed ADD_NETWORK ctrl_iface command to use the same default values
1861	  for variables as empty network definitions read from config file
1862	  would get
1863	* fixed EAP state machine to not discard EAP-Failure messages in many
1864	  cases (e.g., during TLS handshake)
1865	* fixed a infinite loop in private key reading if the configured file
1866	  cannot be parsed successfully
1867	* driver_madwifi: added support for madwifi-ng
1868	* wpa_gui: do not display password/PSK field contents
1869	* wpa_gui: added CA certificate configuration
1870	* driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
1871	* driver_ndis: include Beacon IEs in AssocInfo in order to notice if
1872	  the new AP is using different WPA/RSN IE
1873	* use longer timeout for IEEE 802.11 association to avoid problems with
1874	  drivers that may take more than five second to associate
1875
18762005-10-27 - v0.4.6
1877	* allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
1878	  RSN IE, but WPA IE would match with wpa_supplicant configuration
1879	* added support for named configuration blobs in order to avoid having
1880	  to use file system for external files (e.g., certificates);
1881	  variables can be set to "blob://<blob name>" instead of file path to
1882	  use a named blob; supported fields: pac_file, client_cert,
1883	  private_key
1884	* fixed RSN pre-authentication (it was broken in the clean up of WPA
1885	  state machine interface in v0.4.5)
1886	* driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
1887	  sure the driver configures broadcast decryption correctly
1888	* added ca_path (and ca_path2) configuration variables that can be used
1889	  to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
1890	  system-wide trusted CA list
1891	* added support for starting wpa_supplicant without a configuration
1892	  file (-C argument must be used to set ctrl_interface parameter for
1893	  this case; in addition, -p argument can be used to provide
1894	  driver_param; these new arguments can also be used with a
1895	  configuration to override the values from the configuration)
1896	* added global control interface that can be optionally used for adding
1897	  and removing network interfaces dynamically (-g command line argument
1898	  for both wpa_supplicant and wpa_cli) without having to restart
1899	  wpa_supplicant process
1900	* wpa_gui:
1901	  - try to save configuration whenever something is modified
1902	  - added WEP key configuration
1903	  - added possibility to edit the current network configuration
1904	* driver_ndis: fixed driver polling not to increase frequency on each
1905	  received EAPOL frame due to incorrectly cancelled timeout
1906	* added simple configuration file examples (in examples subdirectory)
1907	* fixed driver_wext.c to filter wireless events based on ifindex to
1908	  avoid interfaces receiving events from other interfaces
1909	* delay sending initial EAPOL-Start couple of seconds to speed up
1910	  authentication for the most common case of Authenticator starting
1911	  EAP authentication immediately after association
1912
19132005-09-25 - v0.4.5
1914	* added a workaround for clearing keys with ndiswrapper to allow
1915	  roaming from WPA enabled AP to plaintext one
1916	* added docbook documentation (doc/docbook) that can be used to
1917	  generate, e.g., man pages
1918	* l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
1919	  PF_PACKET in order to prepare for network devices that do not use
1920	  Ethernet headers (e.g., network stack that includes IEEE 802.11
1921	  header in the frames)
1922	* use receipt of EAPOL-Key frame as a lower layer success indication
1923	  for EAP state machine to allow recovery from dropped EAP-Success
1924	  frame
1925	* cleaned up internal EAPOL frame processing by not including link
1926	  layer (Ethernet) header during WPA and EAPOL/EAP processing; this
1927	  header is added only when transmitted the frame; this makes it easier
1928	  to use wpa_supplicant on link layers that use different header than
1929	  Ethernet
1930	* updated EAP-PSK to use draft 9 by default since this can now be
1931	  tested with hostapd; removed support for draft 3, including
1932	  server_nai configuration option from network blocks
1933	* driver_wired: add PAE address to the multicast address list in order
1934	  to be able to receive EAPOL frames with drivers that do not include
1935	  these multicast addresses by default
1936	* driver_wext: add support for WE-19
1937	* added support for multiple configuration backends (CONFIG_BACKEND
1938	  option); currently, only 'file' is supported (i.e., the format used
1939	  in wpa_supplicant.conf)
1940	* added support for updating configuration ('wpa_cli save_config');
1941	  this is disabled by default and can be enabled with global
1942	  update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
1943	  and wpa_gui to store the configuration changes in a permanent store
1944	* added GET_NETWORK ctrl_iface command
1945	  (e.g., 'wpa_cli get_network 0 ssid')
1946
19472005-08-21 - v0.4.4
1948	* replaced OpenSSL patch for EAP-FAST support
1949	  (openssl-tls-extensions.patch) with a more generic and correct
1950	  patch (the new patch is not compatible with the previous one, so the
1951	  OpenSSL library will need to be patched with the new patch in order
1952	  to be able to build wpa_supplicant with EAP-FAST support)
1953	* added support for using Windows certificate store (through CryptoAPI)
1954	  for client certificate and private key operations (EAP-TLS)
1955	  (see wpa_supplicant.conf for more information on how to configure
1956	  this with private_key)
1957	* ported wpa_gui to Windows
1958	* added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
1959	  built with the open source version of the Qt4 for Windows
1960	* allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
1961	  with drivers that do not support WPA
1962	* ndis_events: fixed Windows 2000 support
1963	* added support for enabling/disabling networks from the list of all
1964	  configured networks ('wpa_cli enable_network <network id>' and
1965	  'wpa_cli disable_network <network id>')
1966	* added support for adding and removing network from the current
1967	  configuration ('wpa_cli add_network' and 'wpa_cli remove_network
1968	  <network id>'); added networks are disabled by default and they can
1969	  be enabled with enable_network command once the configuration is done
1970	  for the new network; note: configuration file is not yet updated, so
1971	  these new networks are lost when wpa_supplicant is restarted
1972	* added support for setting network configuration parameters through
1973	  the control interface, for example:
1974	  wpa_cli set_network 0 ssid "\"my network\""
1975	* fixed parsing of strings that include both " and # within double
1976	  quoted area (e.g., "start"#end")
1977	* added EAP workaround for PEAP session resumption: allow outer,
1978	  i.e., not tunneled, EAP-Success to terminate session since; this can
1979	  be disabled with eap_workaround=0
1980	  (this was allowed for PEAPv1 before, but now it is also allowed for
1981	  PEAPv0 since at least one RADIUS authentication server seems to be
1982	  doing this for PEAPv0, too)
1983	* wpa_gui: added preliminary support for adding new networks to the
1984	  wpa_supplicant configuration (double click on the scan results to
1985	  open network configuration)
1986
19872005-06-26 - v0.4.3
1988	* removed interface for external EAPOL/EAP supplicant (e.g.,
1989	  Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
1990	  anymore and is unlikely to be used by anyone
1991	* driver_ndis: fixed WinPcap 3.0 support
1992	* fixed build with CONFIG_DNET_PCAP=y on Linux
1993	* l2_packet: moved different implementations into separate files
1994	  (l2_packet_*.c)
1995
19962005-06-12 - v0.4.2
1997	* driver_ipw: updated driver structures to match with ipw2200-1.0.4
1998	  (note: ipw2100-1.1.0 is likely to require an update to work with
1999	  this)
2000	* added support for using ap_scan=2 mode with multiple network blocks;
2001	  wpa_supplicant will go through the networks one by one until the
2002	  driver reports a successful association; this uses the same order for
2003	  networks as scan_ssid=1 scans, i.e., the priority field is ignored
2004	  and the network block order in the file is used instead
2005	* fixed a potential issue in RSN pre-authentication ending up using
2006	  freed memory if pre-authentication times out
2007	* added support for matching alternative subject name extensions of the
2008	  authentication server certificate; new configuration variables
2009	  altsubject_match and altsubject_match2
2010	* driver_ndis: added support for IEEE 802.1X authentication with wired
2011	  NDIS drivers
2012	* added support for querying private key password (EAP-TLS) through the
2013	  control interface (wpa_cli/wpa_gui) if one is not included in the
2014	  configuration file
2015	* driver_broadcom: fixed couple of memory leaks in scan result
2016	  processing
2017	* EAP-PAX is now registered as EAP type 46
2018	* fixed EAP-PAX MAC calculation
2019	* fixed EAP-PAX CK and ICK key derivation
2020	* added support for using password with EAP-PAX (as an alternative to
2021	  entering key with eappsk); SHA-1 hash of the password will be used as
2022	  the key in this case
2023	* added support for arbitrary driver interface parameters through the
2024	  configuration file with a new driver_param field; this adds a new
2025	  driver_ops function set_param()
2026	* added possibility to override l2_packet module with driver interface
2027	  API (new send_eapol handler); this can be used to implement driver
2028	  specific TX/RX functions for EAPOL frames
2029	* fixed ctrl_interface_group processing for the case where gid is
2030	  entered as a number, not group name
2031	* driver_test: added support for testing hostapd with wpa_supplicant
2032	  by using test driver interface without any kernel drivers or network
2033	  cards
2034
20352005-05-22 - v0.4.1
2036	* driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
2037	  packets to be encrypted; this was apparently broken by the changed
2038	  ioctl order in v0.4.0
2039	* driver_madwifi: added preliminary support for compiling against 'BSD'
2040	  branch of madwifi CVS tree
2041	* added support for EAP-MSCHAPv2 password retries within the same EAP
2042	  authentication session
2043	* added support for password changes with EAP-MSCHAPv2 (used when the
2044	  password has expired)
2045	* added support for reading additional certificates from PKCS#12 files
2046	  and adding them to the certificate chain
2047	* fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
2048	  were used
2049	* fixed a possible double free in EAP-TTLS fast-reauthentication when
2050	  identity or password is entered through control interface
2051	* display EAP Notification messages to user through control interface
2052	  with "CTRL-EVENT-EAP-NOTIFICATION" prefix
2053	* added GUI version of wpa_cli, wpa_gui; this is not build
2054	  automatically with 'make'; use 'make wpa_gui' to build (this requires
2055	  Qt development tools)
2056	* added 'disconnect' command to control interface for setting
2057	  wpa_supplicant in state where it will not associate before
2058	  'reassociate' command has been used
2059	* added support for selecting a network from the list of all configured
2060	  networks ('wpa_cli select_network <network id>'; this disabled all
2061	  other networks; to re-enable, 'wpa_cli select_network any')
2062	* added support for getting scan results through control interface
2063	* added EAP workaround for PEAPv1 session resumption: allow outer,
2064	  i.e., not tunneled, EAP-Success to terminate session since; this can
2065	  be disabled with eap_workaround=0
2066
20672005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
2068	* added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
2069	  used to reduce the size of the wpa_supplicant considerably if
2070	  debugging code is not needed
2071	* fixed EAPOL-Key validation to drop packets with invalid Key Data
2072	  Length; such frames could have crashed wpa_supplicant due to buffer
2073	  overflow
2074	* added support for wired authentication (IEEE 802.1X on wired
2075	  Ethernet); driver interface 'wired'
2076	* obsoleted set_wpa() handler in the driver interface API (it can be
2077	  replaced by moving enable/disable functionality into init()/deinit())
2078	  (calls to set_wpa() are still present for backwards compatibility,
2079	  but they may be removed in the future)
2080	* driver_madwifi: fixed association in plaintext mode
2081	* modified the EAP workaround that accepts EAP-Success with incorrect
2082	  Identifier to be even less strict about verification in order to
2083	  interoperate with some authentication servers
2084	* added support for sending TLS alerts
2085	* added support for 'any' SSID wildcard; if ssid is not configured or
2086	  is set to an empty string, any SSID will be accepted for non-WPA AP
2087	* added support for asking PIN (for SIM) from frontends (e.g.,
2088	  wpa_cli); if a PIN is needed, but not included in the configuration
2089	  file, a control interface request is sent and EAP processing is
2090	  delayed until the PIN is available
2091	* added support for using external devices (e.g., a smartcard) for
2092	  private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
2093	  new wpa_supplicant.conf variables:
2094	  - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
2095	  - network: engine, engine_id, key_id
2096	* added experimental support for EAP-PAX
2097	* added monitor mode for wpa_cli (-a<path to a program to run>) that
2098	  allows external commands (e.g., shell scripts) to be run based on
2099	  wpa_supplicant events, e.g., when authentication has been completed
2100	  and data connection is ready; other related wpa_cli arguments:
2101	  -B (run in background), -P (write PID file); wpa_supplicant has a new
2102	  command line argument (-W) that can be used to make it wait until a
2103	  control interface command is received in order to avoid missing
2104	  events
2105	* added support for opportunistic WPA2 PMKSA key caching (disabled by
2106	  default, can be enabled with proactive_key_caching=1)
2107	* fixed RSN IE in 4-Way Handshake message 2/4 for the case where
2108	  Authenticator rejects PMKSA caching attempt and the driver is not
2109	  using assoc_info events
2110	* added -P<pid file> argument for wpa_supplicant to write the current
2111	  process id into a file
2112
21132005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
2114	* added new phase1 option parameter, include_tls_length=1, to force
2115	  wpa_supplicant to add TLS Message Length field to all TLS messages
2116	  even if the packet is not fragmented; this may be needed with some
2117	  authentication servers
2118	* fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
2119	  using drivers that take care of AP selection (e.g., when using
2120	  ap_scan=2)
2121	* fixed reprocessing of pending request after ctrl_iface requests for
2122	  identity/password/otp
2123	* fixed ctrl_iface requests for identity/password/otp in Phase 2 of
2124	  EAP-PEAP and EAP-TTLS
2125	* all drivers using driver_wext: set interface up and select Managed
2126	  mode when starting wpa_supplicant; set interface down when exiting
2127	* renamed driver_ipw2100.c to driver_ipw.c since it now supports both
2128	  ipw2100 and ipw2200; please note that this also changed the
2129	  configuration variable in .config to CONFIG_DRIVER_IPW
2130
21312005-01-24 - v0.3.6
2132	* fixed a busy loop introduced in v0.3.5 for scan result processing
2133	  when no matching AP is found
2134
21352005-01-23 - v0.3.5
2136	* added a workaround for an interoperability issue with a Cisco AP
2137	  when using WPA2-PSK
2138	* fixed non-WPA IEEE 802.1X to use the same authentication timeout as
2139	  WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
2140	  retransmission of dropped frames)
2141	* fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
2142	  (e.g., segfault when processing EAPOL-Key frames)
2143	* fixed EAP workaround and fast reauthentication configuration for
2144	  RSN pre-authentication; previously these were disabled and
2145	  pre-authentication would fail if the used authentication server
2146	  requires EAP workarounds
2147	* added support for blacklisting APs that fail or timeout
2148	  authentication in ap_scan=1 mode so that all APs are tried in cases
2149	  where the ones with strongest signal level are failing authentication
2150	* fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
2151	  authentication attempt
2152	* allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
2153	  in the previous authentication (previously, only Phase 1 success was
2154	  verified)
2155
21562005-01-09 - v0.3.4
2157	* added preliminary support for IBSS (ad-hoc) mode configuration
2158	  (mode=1 in network block); this included a new key_mgmt mode
2159	  WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
2160	  key management; see wpa_supplicant.conf for more details and an
2161	  example on how to configure this (note: this is currently implemented
2162	  only for driver_hostapd.c, but the changes should be trivial to add
2163	  in associate() handler for other drivers, too (assuming the driver
2164	  supports WPA-None)
2165	* added preliminary port for native Windows (i.e., no cygwin) using
2166	  mingw
2167
21682005-01-02 - v0.3.3
2169	* added optional support for GNU Readline and History Libraries for
2170	  wpa_cli (CONFIG_READLINE)
2171	* cleaned up EAP state machine <-> method interface and number of
2172	  small problems with error case processing not terminating on
2173	  EAP-Failure but waiting for timeout
2174	* added couple of workarounds for interoperability issues with a
2175	  Cisco AP when using WPA2
2176	* added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
2177	  Note: This requires a patch for openssl to add support for TLS
2178	  extensions and number of workarounds for operations without
2179	  certificates. Proof of concept type of experimental patch is
2180	  included in openssl-tls-extensions.patch.
2181
21822004-12-19 - v0.3.2
2183	* fixed private key loading for cases where passphrase is not set
2184	* fixed Windows/cygwin L2 packet handler freeing; previous version
2185	  could cause a segfault when RSN pre-authentication was completed
2186	* added support for PMKSA caching with drivers that generate RSN IEs
2187	  (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
2188	  but similar code can be easily added to driver_ndiswrapper.c once
2189	  ndiswrapper gets full support for RSN PMKSA caching
2190	* improved recovery from PMKID mismatches by requesting full EAP
2191	  authentication in case of failed PMKSA caching attempt
2192	* driver_ndis: added support for NDIS NdisMIncidateStatus() events
2193	  (this requires that ndis_events is ran while wpa_supplicant is
2194	  running)
2195	* driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
2196	* added support for driver interfaces to replace the interface name
2197	  based on driver/OS specific mapping, e.g., in case of driver_ndis,
2198	  this allows the beginning of the adapter description to be used as
2199	  the interface name
2200	* added support for CR+LF (Windows-style) line ends in configuration
2201	  file
2202	* driver_ndis: enable radio before starting scanning, disable radio
2203	  when exiting
2204	* modified association event handler to set portEnabled = FALSE before
2205	  clearing port Valid in order to reset EAP state machine and avoid
2206	  problems with new authentication getting ignored because of state
2207	  machines ending up in AUTHENTICATED/SUCCESS state based on old
2208	  information
2209	* added support for driver events to add PMKID candidates in order to
2210	  allow drivers to give priority to most likely roaming candidates
2211	* driver_hostap: moved PrivacyInvoked configuration to associate()
2212	  function so that this will not be set for plaintext connections
2213	* added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
2214	  interface can distinguish plaintext and IEEE 802.1X (no WPA)
2215	  authentication
2216	* fixed static WEP key configuration to use broadcast/default type for
2217	  all keys (previously, the default TX key was configured as pairwise/
2218	  unicast key)
2219	* driver_ndis: added legacy WPA capability detection for non-WPA2
2220	  drivers
2221	* added support for setting static WEP keys for IEEE 802.1X without
2222	  dynamic WEP keying (eapol_flags=0)
2223
22242004-12-12 - v0.3.1
2225	* added support for reading PKCS#12 (PFX) files (as a replacement for
2226	  PEM/DER) to get certificate and private key (CONFIG_PKCS12)
2227	* fixed compilation with CONFIG_PCSC=y
2228	* added new ap_scan mode, ap_scan=2, for drivers that take care of
2229	  association, but need to be configured with security policy and SSID,
2230	  e.g., ndiswrapper and NDIS driver; this mode should allow such
2231	  drivers to work with hidden SSIDs and optimized roaming; when
2232	  ap_scan=2 is used, only the first network block in the configuration
2233	  file is used and this configuration should have explicit security
2234	  policy (i.e., only one option in the lists) for key_mgmt, pairwise,
2235	  group, proto variables
2236	* added experimental port of wpa_supplicant for Windows
2237	  - driver_ndis.c driver interface (NDIS OIDs)
2238	  - currently, this requires cygwin and WinPcap
2239	  - small utility, win_if_list, can be used to get interface name
2240	* control interface can now be removed at build time; add
2241	  CONFIG_CTRL_IFACE=y to .config to maintain old functionality
2242	* optional Xsupplicant interface can now be removed at build time;
2243	  (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
2244	* added auth_alg to driver interface associate() parameters to make it
2245	  easier for drivers to configure authentication algorithm as part of
2246	  the association
2247
22482004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
2249	* driver_broadcom: added new driver interface for Broadcom wl.o driver
2250	  (a generic driver for Broadcom IEEE 802.11a/g cards)
2251	* wpa_cli: fixed parsing of -p <path> command line argument
2252	* PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
2253	  ACK, not tunneled EAP-Success (of which only the first byte was
2254	  actually send due to a bug in previous code); this seems to
2255	  interoperate with most RADIUS servers that implements PEAPv1
2256	* PEAPv1: added support for terminating PEAP authentication on tunneled
2257	  EAP-Success message; this can be configured by adding
2258	  peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
2259	  (some RADIUS servers require this whereas others require a tunneled
2260	  reply
2261	* PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
2262	  the old label for key derivation; previously, the default was 1,
2263	  but it looks like most existing PEAPv1 implementations use the old
2264	  label which is thus more suitable default option
2265	* added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
2266	* fixed parsing of wep_tx_keyidx
2267	* added support for configuring list of allowed Phase 2 EAP types
2268	  (for both EAP-PEAP and EAP-TTLS) instead of only one type
2269	* added support for configuring IEEE 802.11 authentication algorithm
2270	  (auth_alg; mainly for using Shared Key authentication with static
2271	  WEP keys)
2272	* added support for EAP-AKA (with UMTS SIM)
2273	* fixed couple of errors in PCSC handling that could have caused
2274	  random-looking errors for EAP-SIM
2275	* added support for EAP-SIM pseudonyms and fast re-authentication
2276	* added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
2277	  session resumption)
2278	* added support for EAP-SIM with two challenges
2279	  (phase1="sim_min_num_chal=3" can be used to require three challenges)
2280	* added support for configuring DH/DSA parameters for an ephemeral DH
2281	  key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
2282	  dh_file and dh_file2 (phase 2); this adds support for using DSA keys
2283	  and optional DH key exchange to achieve forward secracy with RSA keys
2284	* added support for matching subject of the authentication server
2285	  certificate with a substring when using EAP-TLS/PEAP/TTLS; new
2286	  configuration variables subject_match and subject_match2
2287	* changed SSID configuration in driver_wext.c (used by many driver
2288	  interfaces) to use ssid_len+1 as the length for SSID since some Linux
2289	  drivers expect this
2290	* fixed couple of unaligned reads in scan result parsing to fix WPA
2291	  connection on some platforms (e.g., ARM)
2292	* added driver interface for Intel ipw2100 driver
2293	* added support for LEAP with WPA
2294	* added support for larger scan results report (old limit was 4 kB of
2295	  data, i.e., about 35 or so APs) when using Linux wireless extensions
2296	  v17 or newer
2297	* fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
2298	  only if there is a PMKSA cache entry for the current AP
2299	* fixed error handling for case where reading of scan results fails:
2300	  must schedule a new scan or wpa_supplicant will remain waiting
2301	  forever
2302	* changed debug output to remove shared password/key material by
2303	  default; all key information can be included with -K command line
2304	  argument to match the previous behavior
2305	* added support for timestamping debug log messages (disabled by
2306	  default, can be enabled with -t command line argument)
2307	* set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
2308	  if keys are not configured to be used; this fixes IEEE 802.1X mode
2309	  with drivers that use this information to configure whether Privacy
2310	  bit can be in Beacon frames (e.g., ndiswrapper)
2311	* avoid clearing driver keys if no keys have been configured since last
2312	  key clear request; this seems to improve reliability of group key
2313	  handshake for ndiswrapper & NDIS driver which seems to be suffering
2314	  of some kind of timing issue when the keys are cleared again after
2315	  association
2316	* changed driver interface API:
2317	  - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
2318	    version is being used (now, this is set to 2; previously, it was
2319	    not defined)
2320	  - pass pointer to private data structure to all calls
2321	  - the new API is not backwards compatible; all in-tree driver
2322	    interfaces has been converted to the new API
2323	* added support for controlling multiple interfaces (radios) per
2324	  wpa_supplicant process; each interface needs to be listed on the
2325	  command line (-c, -i, -D arguments) with -N as a separator
2326	  (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
2327	* added a workaround for EAP servers that incorrectly use same Id for
2328	  sequential EAP packets
2329	* changed libpcap/libdnet configuration to use .config variable,
2330	  CONFIG_DNET_PCAP, instead of requiring Makefile modification
2331	* improved downgrade attack detection in IE verification of msg 3/4:
2332	  verify both WPA and RSN IEs, if present, not only the selected one;
2333	  reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
2334	  Probe Response frame, and RSN is enabled in wpa_supplicant
2335	  configuration
2336	* fixed WPA msg 3/4 processing to allow Key Data field contain other
2337	  IEs than just one WPA IE
2338	* added support for FreeBSD and driver interface for the BSD net80211
2339	  layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
2340	  required kernel mods have not yet been committed
2341	* made EAP workarounds configurable; enabled by default, can be
2342	  disabled with network block option eap_workaround=0
2343
23442004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
2345	* resolved couple of interoperability issues with EAP-PEAPv1 and
2346	  Phase 2 (inner EAP) fragment reassembly
2347	* driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
2348	  AP is using non-zero key index for the unicast key and key index zero
2349	  for the broadcast key
2350	* driver_hostap: fixed IEEE 802.1X WEP key updates and
2351	  re-authentication by allowing unencrypted EAPOL frames when not using
2352	  WPA
2353	* added a new driver interface, 'wext', which uses only standard,
2354	  driver independent functionality in Linux wireless extensions;
2355	  currently, this can be used only for non-WPA IEEE 802.1X mode, but
2356	  eventually, this is to be extended to support full WPA/WPA2 once
2357	  Linux wireless extensions get support for this
2358	* added support for mode in which the driver is responsible for AP
2359	  scanning and selection; this is disabled by default and can be
2360	  enabled with global ap_scan=0 variable in wpa_supplicant.conf;
2361	  this mode can be used, e.g., with generic 'wext' driver interface to
2362	  use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
2363	  supporting wireless extensions.
2364	* driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
2365	  operation with an AP that does not include SSID in the Beacon frames)
2366	* added support for new EAP authentication methods:
2367	  EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
2368	* added support for asking one-time-passwords from frontends (e.g.,
2369	  wpa_cli); this 'otp' command works otherwise like 'password' command,
2370	  but the password is used only once and the frontend will be asked for
2371	  a new password whenever a request from authenticator requires a
2372	  password; this can be used with both EAP-OTP and EAP-GTC
2373	* changed wpa_cli to automatically re-establish connection so that it
2374	  does not need to be re-started when wpa_supplicant is terminated and
2375	  started again
2376	* improved user data (identity/password/otp) requests through
2377	  frontends: process pending EAPOL packets after getting new
2378	  information so that full authentication does not need to be
2379	  restarted; in addition, send pending requests again whenever a new
2380	  frontend is attached
2381	* changed control frontends to use a new directory for socket files to
2382	  make it easier for wpa_cli to automatically select between interfaces
2383	  and to provide access control for the control interface;
2384	  wpa_supplicant.conf: ctrl_interface is now a path
2385	  (/var/run/wpa_supplicant is the recommended path) and
2386	  ctrl_interface_group can be used to select which group gets access to
2387	  the control interface;
2388	  wpa_cli: by default, try to connect to the first interface available
2389	  in /var/run/wpa_supplicant; this path can be overridden with -p option
2390	  and an interface can be selected with -i option (i.e., in most common
2391	  cases, wpa_cli does not need to get any arguments)
2392	* added support for LEAP
2393	* added driver interface for Linux ndiswrapper
2394	* added priority option for network blocks in the configuration file;
2395	  this allows networks to be grouped based on priority (the scan
2396	  results are searched for matches with network blocks in this order)
2397
23982004-06-20 - v0.2.3
2399	* sort scan results to improve AP selection
2400	* fixed control interface socket removal for some error cases
2401	* improved scan requesting and authentication timeout
2402	* small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
2403	  TLS processing
2404	* PEAP version can now be forced with phase1="peapver=<ver>"
2405	  (mostly for testing; by default, the highest version supported by
2406	  both the Supplicant and Authentication Server is selected
2407	  automatically)
2408	* added support for madwifi driver (Atheros ar521x)
2409	* added a workaround for cases where AP sets Install Tx/Rx bit for
2410	  WPA Group Key messages when pairwise keys are used (without this,
2411	  the Group Key would be used for Tx and the AP would drop frames
2412	  from the station)
2413	* added GSM SIM/USIM interface for GSM authentication algorithm for
2414	  EAP-SIM; this requires pcsc-lite
2415	* added support for ATMEL AT76C5XXx driver
2416	* fixed IEEE 802.1X WEP key derivation in the case where Authenticator
2417	  does not include key data in the EAPOL-Key frame (i.e., part of
2418	  EAP keying material is used as data encryption key)
2419	* added support for using plaintext and static WEP networks
2420	  (key_mgmt=NONE)
2421
24222004-05-31 - v0.2.2
2423	* added support for new EAP authentication methods:
2424	  EAP-TTLS/EAP-MD5-Challenge
2425	  EAP-TTLS/EAP-GTC
2426	  EAP-TTLS/EAP-MSCHAPv2
2427	  EAP-TTLS/EAP-TLS
2428	  EAP-TTLS/MSCHAPv2
2429	  EAP-TTLS/MSCHAP
2430	  EAP-TTLS/PAP
2431	  EAP-TTLS/CHAP
2432	  EAP-PEAP/TLS
2433	  EAP-PEAP/GTC
2434	  EAP-PEAP/MD5-Challenge
2435	  EAP-GTC
2436	  EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
2437	* added support for anonymous identity (to be used when identity is
2438	  sent in plaintext; real identity will be used within TLS protected
2439	  tunnel (e.g., with EAP-TTLS)
2440	* added event messages from wpa_supplicant to frontends, e.g., wpa_cli
2441	* added support for requesting identity and password information using
2442	  control interface; in other words, the password for EAP-PEAP or
2443	  EAP-TTLS does not need to be included in the configuration file since
2444	  a frontand (e.g., wpa_cli) can ask it from the user
2445	* improved RSN pre-authentication to use a candidate list and process
2446	  all candidates from each scan; not only one per scan
2447	* fixed RSN IE and WPA IE capabilities field parsing
2448	* ignore Tx bit in GTK IE when Pairwise keys are used
2449	* avoid making new scan requests during IEEE 802.1X negotiation
2450	* use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
2451	  with TLS support (this replaces the included implementation with
2452	  library code to save about 8 kB since the library code is needed
2453	  anyway for TLS)
2454	* fixed WPA-PSK only mode when compiled without IEEE 802.1X support
2455	  (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
2456
24572004-05-06 - v0.2.1
2458	* added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
2459	  Supplicant
2460	  - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
2461	  - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
2462	  - EAP-MD5 (cannot be used with WPA-RADIUS)
2463	    [draft-ietf-eap-rfc2284bis-09.txt]
2464	  - EAP-TLS [RFC 2716]
2465	  - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
2466	  - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
2467	    [draft-kamath-pppext-eap-mschapv2-00.txt]
2468	    (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
2469	    default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
2470	  - new configuration file options: eap, identity, password, ca_cert,
2471	    client_cert, privatekey, private_key_passwd
2472	  - Xsupplicant is not required anymore, but it can be used by
2473	    disabling the internal IEEE 802.1X Supplicant with -e command line
2474	    option
2475	  - this code is not included in the default build; Makefile need to
2476	    be edited for this (uncomment lines for selected functionality)
2477	  - EAP-TLS and EAP-PEAP require openssl libraries
2478	* use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
2479	* added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
2480	  (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
2481	   EAPOL-Key frames instead of WPA key handshakes)
2482	* added support for IEEE 802.11i/RSN (WPA2)
2483	  - improved PTK Key Handshake
2484	  - PMKSA caching, pre-authentication
2485	* fixed wpa_supplicant to ignore possible extra data after WPA
2486	  EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
2487	  TPTK' error from message 3 of 4-Way Handshake in case the AP
2488	  includes extra data after the EAPOL-Key)
2489	* added interface for external programs (frontends) to control
2490	  wpa_supplicant
2491	  - CLI example (wpa_cli) with interactive mode and command line
2492	    mode
2493	  - replaced SIGUSR1 status/statistics with the new control interface
2494	* made some feature compile time configurable
2495	  - .config file for make
2496	  - driver interfaces (hostap, hermes, ..)
2497	  - EAPOL/EAP functions
2498
24992004-02-15 - v0.2.0
2500	* Initial version of wpa_supplicant
2501
