    741 	  remotely over UDP (CONFIG_CTRL_IFACE=udp-remote) for testing purposes
    742 	* wpa_cli: extended tab completion to more commands
    743 	* changed SSID output to use printf-escaped strings instead of masking
    744 	  of non-ASCII characters
    745 	  - SSID can now be configured in the same format: ssid=P"abc\x00test"
    746 	* removed default ACM=1 from AC_VO and AC_VI
    747 	* added optional "ht40" argument for P2P ctrl_iface commands to allow

    753 	    OpenSSL FIPS object module
    754 	  - replace low level OpenSSL AES API calls to use EVP
    755 	  - use OpenSSL keying material exporter when possible
    756 	  - do not export TLS keys in FIPS mode
    757 	  - remove MD5 from CONFIG_FIPS=y builds

    763 	* added mechanism to disable TLS Session Ticket extension
    764 	  - a workaround for servers that do not support TLS extensions that
    765 	    was enabled by default in recent OpenSSL versions
    766 	  - tls_disable_session_ticket=1
    767 	  - automatically disable TLS Session Ticket extension by default when
    768 	    using EAP-TLS/PEAP/TTLS (i.e., only use it with EAP-FAST)
    769 	* changed VENDOR-TEST EAP method to use proper private enterprise number
    770 	  (this will not interoperate with older versions)
    771 	* disable network block temporarily on authentication failures
    772 	* improved WPS AP selection during WPS PIN iteration
    773 	* added support for configuring GCMP cipher for IEEE 802.11ad

    776 	  - SET wifi_display <0/1> to disable/enable WFD support
    777 	  - WFD service discovery
    778 	  - an external program is needed to manage the audio/video streaming
    779 	    and codecs
    780 	* optimized scan result use for network selection
    781 	  - use the internal BSS table instead of raw scan results
    782 	  - allow unnecessary scans to be skipped if fresh information is
    783 	    available (e.g., after GAS/ANQP round for Interworking)

    796 	  for the same key
    797 	* use deauthentication instead of disassociation for all disconnection
    798 	  operations; this removes the now unused disassociate() wpa_driver_ops
    799 	  callback
    800 	* optimized PSK generation on P2P GO by caching results to avoid
    801 	  multiple PBKDF2 operations

    807 	* added basic support for 60 GHz band
    808 	* extend EAPOL frames processing workaround for roaming cases
    809 	  (postpone processing of unexpected EAPOL frame until association
    810 	  event to handle reordered events)
    811 
    812 2012-05-10 - v1.0
    813 	* bsd: Add support for setting HT values in IFM_MMASK.
    814 	* Delay STA entry removal until Deauth/Disassoc TX status in AP mode.
    815 	  This allows the driver to use PS buffering of Deauthentication and
    816 	  Disassociation frames when the STA is in power save sleep. Only
    817 	  available with drivers that provide TX status events for Deauth/
    818 	  Disassoc frames (nl80211).
    819 	* Drop oldest unknown BSS table entries first. This makes it less
    820 	  likely to hit connection issues in environments with huge number
    821 	  of visible APs.
    822 	* Add systemd support.
    823 	* Add support for setting the syslog facility from the config file
    824 	  at build time.
    825 	* atheros: Add support for IEEE 802.11w configuration.
    826 	* AP mode: Allow enable HT20 if driver supports it, by setting the
    827 	  config parameter ieee80211n.
    828 	* Allow AP mode to disconnect STAs based on low ACK condition (when
    829 	  the data connection is not working properly, e.g., due to the STA
    830 	  going outside the range of the AP). Disabled by default, enable by
    831 	  config option disassoc_low_ack.
    832 	* nl80211:
    833 	  - Support GTK rekey offload.
    834 	  - Support PMKSA candidate events. This adds support for RSN
    835 	    pre-authentication with nl80211 interface and drivers that handle
    836 	    roaming internally.
    837 	* dbus:
    838 	  - Add a DBus signal for EAP SM requests, emitted on the Interface
    839 	    object.
    840 	  - Export max scan ssids supported by the driver as MaxScanSSID.
    841 	  - Add signal Certification for information about server certification.
    842 	  - Add BSSExpireAge and BSSExpireCount interface properties and
    843 	    support set/get, which allows for setting BSS cache expiration age
    844 	    and expiration scan count.
    845 	  - Add ConfigFile to AddInterface properties.
    846 	  - Add Interface.Country property and support to get/set the value.
    847 	  - Add DBus property CurrentAuthMode.
    848 	  - P2P DBus API added.
    849 	  - Emit property changed events (for property BSSs) when adding/
    850 	    removing BSSs.
    851 	  - Treat '' in SSIDs of Interface.Scan as a request for broadcast
    852 	    scan, instead of ignoring it.
    853 	  - Add DBus getter/setter for FastReauth.
    854 	  - Raise PropertiesChanged on org.freedesktop.DBus.Properties.
    855 	* wpa_cli:
    856 	  - Send AP-STA-DISCONNECTED event when an AP disconnects a station
    857 	    due to inactivity.
    858 	  - Make second argument to set command optional. This can be used to
    859 	    indicate a zero length value.
    860 	  - Add signal_poll command.
    861 	  - Add bss_expire_age and bss_expire_count commands to set/get BSS
    862 	    cache expiration age and expiration scan count.
    863 	  - Add ability to set scan interval (the time in seconds wpa_s waits
    864 	    before requesting a new scan after failing to find a suitable
    865 	    network in scan results) using scan_interval command.
    866 	  - Add event CTRL-EVENT-ASSOC-REJECT for association rejected.
    867 	  - Add command get version, that returns wpa_supplicant version string.
    868 	  - Add command sta_autoconnect for disabling automatic reconnection
    869 	    on receiving disconnection event.
    870 	  - Setting bssid parameter to an empty string "" or any can now be
    871 	    used to clear the bssid_set flag in a network block, i.e., to remove
    872 	    bssid filtering.
    873 	  - Add tdls_testing command to add a special testing feature for
    874 	    changing TDLS behavior. Build param CONFIG_TDLS_TESTING must be
    875 	    enabled as well.
    876 	  - For interworking, add wpa_cli commands interworking_select,
    877 	    interworking_connect, anqp_get, fetch_anqp, and stop_fetch_anqp.
    878 	  - Many P2P commands were added. See README-P2P.

    882 	    debugging level and to change the log level during run time.
    883 	  - Add note command, which can be used to insert notes to the debug
    884 	    log.
    885 	  - Add internal line edit implementation. CONFIG_WPA_CLI_EDIT=y
    886 	    can now be used to build wpa_cli with internal implementation of
    887 	    line editing and history support. This can be used as a replacement
    888 	    for CONFIG_READLINE=y.
    889 	* AP mode: Add max_num_sta config option, which can be used to limit
    890 	  the number of stations allowed to connect to the AP.
    891 	* Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad
    892 	  config file.
    893 	* wext: Increase scan timeout from 5 to 10 seconds.
    894 	* Add blacklist command, allowing an external program to
    895 	  manage the BSS blacklist and display its current contents.
    896 	* WPS:
    897 	  - Add wpa_cli wps_pin get command for generating random PINs. This can
    898 	    be used in a UI to generate a PIN without starting WPS (or P2P)
    899 	    operation.
    900 	  - Set RF bands based on driver capabilities, instead of hardcoding
    901 	    them.
    902 	  - Add mechanism for indicating non-standard WPS errors.
    903 	  - Add CONFIG_WPS_REG_DISABLE_OPEN=y option to disable open networks
    904 	    by default.
    905 	  - Add wps_ap_pin cli command for wpa_supplicant AP mode.
    906 	  - Add wps_check_pin cli command for processing PIN from user input.
    907 	    UIs can use this command to process a PIN entered by a user and to
    908 	    validate the checksum digit (if present).
    909 	  - Cancel WPS operation on PBC session overlap detection.
    910 	  - New wps_cancel command in wpa_cli will cancel a pending WPS
    911 	    operation.
    912 	  - wpa_cli action: Add WPS_EVENT_SUCCESS and WPS_EVENT_FAIL handlers.
    913 	  - Trigger WPS config update on Manufacturer, Model Name, Model
    914 	    Number, and Serial Number changes.
    915 	  - Fragment size is now configurable for EAP-WSC peer. Use
    916 	    wpa_cli set wps_fragment_size <val>.
    917 	  - Disable AP PIN after 10 consecutive failures. Slow down attacks on
    918 	    failures up to 10.
    919 	  - Allow AP to start in Enrollee mode without AP PIN for probing, to
    920 	    be compatible with Windows 7.
    921 	  - Add Config Error into WPS-FAIL events to provide more info to the
    922 	    user on how to resolve the issue.
    923 	  - Label and Display config methods are not allowed to be enabled
    924 	    at the same time, since it is unclear which PIN to use if both
    925 	    methods are advertised.
    926 	  - When controlling multiple interfaces:
    927 	     - apply WPS commands to all interfaces configured to use WPS
    928 	     - apply WPS config changes to all interfaces that use WPS
    929 	     - when an attack is detected on any interface, disable AP PIN on
    930 	       all interfaces
    931 	* WPS ER:
    932 	  - Add special AP Setup Locked mode to allow read only ER.
    933 	    ap_setup_locked=2 can now be used to enable a special mode where
    934 	    WPS ER can learn the current AP settings, but cannot change them.
    935 	  - Show SetSelectedRegistrar events as ctrl_iface events
    936 	  - Add wps_er_set_config to enroll a network based on a local
    937 	    network configuration block instead of having to (re-)learn the
    938 	    current AP settings with wps_er_learn.
    939 	  - Allow AP filtering based on IP address, add ctrl_iface event for
    940 	    learned AP settings, add wps_er_config command to configure an AP.
    941 	* WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2)
    942 	  - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool
    943 	    for testing protocol extensibility.
    944 	  - Add build option CONFIG_WPS_STRICT to allow disabling of WPS
    945 	    workarounds.
    946 	  - Add support for AuthorizedMACs attribute.
    947 	* TDLS:
    948 	  - Propogate TDLS related nl80211 capability flags from kernel and
    949 	    add them as driver capability flags. If the driver doesn't support
    950 	    capabilities, assume TDLS is supported internally. When TDLS is
    951 	    explicitly not supported, disable all user facing TDLS operations.
    952 	  - Allow TDLS to be disabled at runtime (mostly for testing).
    953 	    Use set tdls_disabled.
    954 	  - Honor AP TDLS settings that prohibit/allow TDLS.
    955 	  - Add a special testing feature for changing TDLS behavior. Use
    956 	    CONFIG_TDLS_TESTING build param to enable. Configure at runtime
    957 	    with tdls_testing cli command.
    958 	  - Add support for TDLS 802.11z.
    959 	* wlantest: Add a tool wlantest for IEEE802.11 protocol testing.

    961 	  for realtime capturing or from pcap files for offline analysis.
    962 	* Interworking: Support added for 802.11u. Enable in .config with
    963 	  CONFIG_INTERWORKING. See wpa_supplicant.conf for config parameters
    964 	  for interworking. wpa_cli commands added to support this are
    965 	  interworking_select, interworking_connect, anqp_get, fetch_anqp,
    966 	  and stop_fetch_anqp.
    967 	* Android: Add build and runtime support for Android wpa_supplicant.
    968 	* bgscan learn: Add new bgscan that learns BSS information based on
    969 	  previous scans, and uses that information to dynamically generate
    970 	  the list of channels for background scans.
    971 	* Add a new debug message level for excessive information. Use
    972 	  -ddd to enable.
    973 	* TLS: Add support for tls_disable_time_checks=1 in client mode.
    974 	* Internal TLS:
    975 	  - Add support for TLS v1.1 (RFC 4346). Enable with build parameter
    976 	    CONFIG_TLSV11.
    977 	  - Add domainComponent parser for X.509 names.
    978 	* Linux: Add RFKill support by adding an interface state "disabled".
    979 	* Reorder some IEs to get closer to IEEE 802.11 standard. Move
    980 	  WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames.
    981 	  Move HT IEs to be later in (Re)Assoc Resp.
    982 	* Solaris: Add support for wired 802.1X client.
    983 	* Wi-Fi Direct support. See README-P2P for more information.
    984 	* Many bugfixes.
    985 
    986 2010-04-18 - v0.7.2
    987 	* nl80211: fixed number of issues with roaming
    988 	* avoid unnecessary roaming if multiple APs with similar signal
    989 	  strength are present in scan results
    990 	* add TLS client events and server probing to ease design of
    991 	  automatic detection of EAP parameters
    992 	* add option for server certificate matching (SHA256 hash of the
    993 	  certificate) instead of trusted CA certificate configuration
    994 	* bsd: Cleaned up driver wrapper and added various low-level
    995 	  configuration options
    996 	* wpa_gui-qt4: do not show too frequent WPS AP available events as
    997 	  tray messages
    998 	* TNC: fixed issues with fragmentation
    999 	* EAP-TNC: add Flags field into fragment acknowledgement (needed to
   1000 	  interoperate with other implementations; may potentially breaks
   1001 	  compatibility with older wpa_supplicant/hostapd versions)
   1002 	* wpa_cli: added option for using a separate process to receive event
   1003 	  messages to reduce latency in showing these
   1004 	  (CFLAGS += -DCONFIG_WPA_CLI_FORK=y in .config to enable this)
   1005 	* maximum BSS table size can now be configured (bss_max_count)
   1006 	* BSSes to be included in the BSS table can be filtered based on
   1007 	  configured SSIDs to save memory (filter_ssids)
   1008 	* fix number of issues with IEEE 802.11r/FT; this version is not
   1009 	  backwards compatible with old versions
   1010 	* nl80211: add support for IEEE 802.11r/FT protocol (both over-the-air
   1011 	  and over-the-DS)
   1012 	* add freq_list network configuration parameter to allow the AP
   1013 	  selection to filter out entries based on the operating channel
   1014 	* add signal strength change events for bgscan; this allows more
   1015 	  dynamic changes to background scanning interval based on changes in
   1016 	  the signal strength with the current AP; this improves roaming within
   1017 	  ESS quite a bit, e.g., with bgscan="simple:30:-45:300" in the network
   1018 	  configuration block to request background scans less frequently when
   1019 	  signal strength remains good and to automatically trigger background
   1020 	  scans whenever signal strength drops noticeably
   1021 	  (this is currently only available with nl80211)
   1022 	* add BSSID and reason code (if available) to disconnect event messages
   1023 	* wpa_gui-qt4: more complete support for translating the GUI with
   1024 	  linguist and add German translation
   1025 	* fix DH padding with internal crypto code (mainly, for WPS)
   1026 	* do not trigger initial scan automatically anymore if there are no
   1027 	  enabled networks
   1028 
   1029 2010-01-16 - v0.7.1
   1030 	* cleaned up driver wrapper API (struct wpa_driver_ops); the new API
   1031 	  is not fully backwards compatible, so out-of-tree driver wrappers
   1032 	  will need modifications
   1033 	* cleaned up various module interfaces
   1034 	* merge hostapd and wpa_supplicant developers' documentation into a
   1035 	  single document
   1036 	* nl80211: use explicit deauthentication to clear cfg80211 state to
   1037 	  avoid issues when roaming between APs
   1038 	* dbus: major design changes in the new D-Bus API
   1039 	  (fi.w1.wpa_supplicant1)
   1040 	* nl80211: added support for IBSS networks
   1041 	* added internal debugging mechanism with backtrace support and memory
   1042 	  allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y)
   1043 	* added WPS ER unsubscription command to more cleanly unregister from
   1044 	  receiving UPnP events when ER is terminated
   1045 	* cleaned up AP mode operations to avoid need for virtual driver_ops
   1046 	  wrapper
   1047 	* added BSS table to maintain more complete scan result information
   1048 	  over multiple scans (that may include only partial results)
   1049 	* wpa_gui-qt4: update Peers dialog information more dynamically while
   1050 	  the dialog is kept open
   1051 	* fixed PKCS#12 use with OpenSSL 1.0.0
   1052 	* driver_wext: Added cfg80211-specific optimization to avoid some
   1053 	  unnecessary scans and to speed up association
   1054 
   1055 2009-11-21 - v0.7.0
   1056 	* increased wpa_cli ping interval to 5 seconds and made this
   1057 	  configurable with a new command line options (-G<seconds>)
   1058 	* fixed scan buffer processing with WEXT to handle up to 65535
   1059 	  byte result buffer (previously, limited to 32768 bytes)
   1060 	* allow multiple driver wrappers to be specified on command line
   1061 	  (e.g., -Dnl80211,wext); the first one that is able to initialize the
   1062 	  interface will be used
   1063 	* added support for multiple SSIDs per scan request to optimize
   1064 	  scan_ssid=1 operations in ap_scan=1 mode (i.e., search for hidden
   1065 	  SSIDs); this requires driver support and can currently be used only
   1066 	  with nl80211
   1067 	* added support for WPS USBA out-of-band mechanism with USB Flash
   1068 	  Drives (UFD) (CONFIG_WPS_UFD=y)
   1069 	* driver_ndis: add PAE group address to the multicast address list to
   1070 	  fix wired IEEE 802.1X authentication
   1071 	* fixed IEEE 802.11r key derivation function to match with the standard
   1072 	  (note: this breaks interoperability with previous version) [Bug 303]
   1073 	* added better support for drivers that allow separate authentication
   1074 	  and association commands (e.g., mac80211-based Linux drivers with
   1075 	  nl80211; SME in wpa_supplicant); this allows over-the-air FT protocol
   1076 	  to be used (IEEE 802.11r)
   1077 	* fixed SHA-256 based key derivation function to match with the
   1078 	  standard when using CCMP (for IEEE 802.11r and IEEE 802.11w)
   1079 	  (note: this breaks interoperability with previous version) [Bug 307]
   1080 	* use shared driver wrapper files with hostapd
   1081 	* added AP mode functionality (CONFIG_AP=y) with mode=2 in the network
   1082 	  block; this can be used for open and WPA2-Personal networks
   1083 	  (optionally, with WPS); this links in parts of hostapd functionality
   1084 	  into wpa_supplicant
   1085 	* wpa_gui-qt4: added new Peers dialog to show information about peers
   1086 	  (other devices, including APs and stations, etc. in the neighborhood)
   1087 	* added support for WPS External Registrar functionality (configure APs
   1088 	  and enroll new devices); can be used with wpa_gui-qt4 Peers dialog
   1089 	  and wpa_cli commands wps_er_start, wps_er_stop, wps_er_pin,
   1090 	  wps_er_pbc, wps_er_learn
   1091 	  (this can also be used with a new 'none' driver wrapper if no
   1092 	  wireless device or IEEE 802.1X on wired is needed)
   1093 	* driver_nl80211: multiple updates to provide support for new Linux
   1094 	  nl80211/mac80211 functionality
   1095 	* updated management frame protection to use IEEE Std 802.11w-2009
   1096 	* fixed number of small WPS issues and added workarounds to
   1097 	  interoperate with common deployed broken implementations
   1098 	* added support for NFC out-of-band mechanism with WPS
   1099 	* driver_ndis: fixed wired IEEE 802.1X authentication with PAE group
   1100 	  address frames
   1101 	* added preliminary support for IEEE 802.11r RIC processing
   1102 	* added support for specifying subset of enabled frequencies to scan
   1103 	  (scan_freq option in the network configuration block); this can speed
   1104 	  up scanning process considerably if it is known that only a small
   1105 	  subset of channels is actually used in the network (this is currently
   1106 	  supported only with -Dnl80211)
   1107 	* added a workaround for race condition between receiving the
   1108 	  association event and the following EAPOL-Key
   1109 	* added background scan and roaming infrastructure to allow
   1110 	  network-specific optimizations to be used to improve roaming within
   1111 	  an ESS (same SSID)
   1112 	* added new DBus interface (fi.w1.wpa_supplicant1)
   1113 
   1114 2009-01-06 - v0.6.7
   1115 	* added support for Wi-Fi Protected Setup (WPS)
   1116 	  (wpa_supplicant can now be configured to act as a WPS Enrollee to
   1117 	  enroll credentials for a network using PIN and PBC methods; in
   1118 	  addition, wpa_supplicant can act as a wireless WPS Registrar to
   1119 	  configure an AP); WPS support can be enabled by adding CONFIG_WPS=y
   1120 	  into .config and setting the runtime configuration variables in
   1121 	  wpa_supplicant.conf (see WPS section in the example configuration
   1122 	  file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to
   1123 	  manage WPS negotiation; see README-WPS for more details
   1124 	* added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
   1125 	* added support for using driver_test over UDP socket
   1126 	* fixed PEAPv0 Cryptobinding interoperability issue with Windows Server
   1127 	  2008 NPS; optional cryptobinding is now enabled (again) by default
   1128 	* fixed PSK editing in wpa_gui
   1129 	* changed EAP-GPSK to use the IANA assigned EAP method type 51
   1130 	* added a Windows installer that includes WinPcap and all the needed
   1131 	  DLLs; in addition, it set up the registry automatically so that user
   1132 	  will only need start wpa_gui to get prompted to start the wpasvc
   1133 	  servide and add a new interface if needed through wpa_gui dialog
   1134 	* updated management frame protection to use IEEE 802.11w/D7.0
   1135 
   1136 2008-11-23 - v0.6.6
   1137 	* added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
   1138 	  (can be used to simulate test SIM/USIM card with a known private key;
   1139 	  enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
   1140 	  and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
   1141 	* added a new network configuration option, wpa_ptk_rekey, that can be
   1142 	  used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
   1143 	  against TKIP deficiencies
   1144 	* added an optional mitigation mechanism for certain attacks against
   1145 	  TKIP by delaying Michael MIC error reports by a random amount of time
   1146 	  between 0 and 60 seconds; this can be enabled with a build option
   1147 	  CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
   1148 	* fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
   1149 	  not bytes
   1150 	* updated OpenSSL code for EAP-FAST to use an updated version of the
   1151 	  session ticket overriding API that was included into the upstream
   1152 	  OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
   1153 	  needed with that version anymore)
   1154 	* updated userspace MLME instructions to match with the current Linux
   1155 	  mac80211 implementation; please also note that this can only be used
   1156 	  with driver_nl80211.c (the old code from driver_wext.c was removed)
   1157 	* added support (Linux only) for RoboSwitch chipsets (often found in
   1158 	  consumer grade routers); driver interface 'roboswitch'
   1159 	* fixed canceling of PMKSA caching when using drivers that generate
   1160 	  RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
   1161 	  about
   1162 
   1163 2008-11-01 - v0.6.5
   1164 	* added support for SHA-256 as X.509 certificate digest when using the
   1165 	  internal X.509/TLSv1 implementation
   1166 	* updated management frame protection to use IEEE 802.11w/D6.0
   1167 	* added support for using SHA256-based stronger key derivation for WPA2
   1168 	  (IEEE 802.11w)
   1169 	* fixed FT (IEEE 802.11r) authentication after a failed association to
   1170 	  use correct FTIE
   1171 	* added support for configuring Phase 2 (inner/tunneled) authentication
   1172 	  method with wpa_gui-qt4
   1173 
   1174 2008-08-10 - v0.6.4
   1175 	* added support for EAP Sequences in EAP-FAST Phase 2
   1176 	* added support for using TNC with EAP-FAST
   1177 	* added driver_ps3 for the PS3 Linux wireless driver
   1178 	* added support for optional cryptobinding with PEAPv0
   1179 	* fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
   1180 	  allow fallback to full handshake if server rejects PAC-Opaque
   1181 	* added fragmentation support for EAP-TNC
   1182 	* added support for parsing PKCS #8 formatted private keys into the
   1183 	  internal TLS implementation (both PKCS #1 RSA key and PKCS #8
   1184 	  encapsulated RSA key can now be used)
   1185 	* added option of using faster, but larger, routines in the internal
   1186 	  LibTomMath (for internal TLS implementation) to speed up DH and RSA
   1187 	  calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
   1188 	* fixed race condition between disassociation event and group key
   1189 	  handshake to avoid getting stuck in incorrect state [Bug 261]
   1190 	* fixed opportunistic key caching (proactive_key_caching)
   1191 
   1192 2008-02-22 - v0.6.3
   1193 	* removed 'nai' and 'eappsk' network configuration variables that were
   1194 	  previously used for configuring user identity and key for EAP-PSK,
   1195 	  EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
   1196 	  replacement for 'nai' (if old configuration used a separate
   1197 	  'identity' value, that would now be configured as
   1198 	  'anonymous_identity'). 'password' field is now used as the
   1199 	  replacement for 'eappsk' (it can also be set using hexstring to
   1200 	  present random binary data)
   1201 	* removed '-w' command line parameter (wait for interface to be added,
   1202 	  if needed); cleaner way of handling this functionality is to use an
   1203 	  external mechanism (e.g., hotplug scripts) that start wpa_supplicant
   1204 	  when an interface is added
   1205 	* updated FT support to use the latest draft, IEEE 802.11r/D9.0
   1206 	* added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
   1207 	  indicating when new scan results become available
   1208 	* added new ctrl_iface command, BSS, to allow scan results to be
   1209 	  fetched without hitting the message size limits (this command
   1210 	  can be used to iterate through the scan results one BSS at the time)
   1211 	* fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
   1212 	  attributes in EAP-SIM Start/Response when using fast reauthentication
   1213 	* fixed EAPOL not to end up in infinite loop when processing dynamic
   1214 	  WEP keys with IEEE 802.1X
   1215 	* fixed problems in getting NDIS events from WMI on Windows 2000
   1216 
   1217 2008-01-01 - v0.6.2
   1218 	* added support for Makefile builds to include debug-log-to-a-file
   1219 	  functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
   1220 	* fixed EAP-SIM and EAP-AKA message parser to validate attribute
   1221 	  lengths properly to avoid potential crash caused by invalid messages
   1222 	* added data structure for storing allocated buffers (struct wpabuf);
   1223 	  this does not affect wpa_supplicant usage, but many of the APIs
   1224 	  changed and various interfaces (e.g., EAP) is not compatible with old
   1225 	  versions
   1226 	* added support for protecting EAP-AKA/Identity messages with
   1227 	  AT_CHECKCODE (optional feature in RFC 4187)
   1228 	* added support for protected result indication with AT_RESULT_IND for
   1229 	  EAP-SIM and EAP-AKA (phase1="result_ind=1")
   1230 	* added driver_wext workaround for race condition between scanning and
   1231 	  association with drivers that take very long time to scan all
   1232 	  channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
   1233 	  using a longer hardcoded timeout for the scan if the driver supports
   1234 	  notifications for scan completion (SIOCGIWSCAN event); this helps,
   1235 	  e.g., in cases where wpa_supplicant and madwifi driver ended up in
   1236 	  loop where the driver did not even try to associate
   1237 	* stop EAPOL timer tick when no timers are in use in order to reduce
   1238 	  power consumption (no need to wake up the process once per second)
   1239 	  [Bug 237]
   1240 	* added support for privilege separation (run only minimal part of
   1241 	  wpa_supplicant functionality as root and rest as unprivileged,
   1242 	  non-root process); see 'Privilege separation' in README for details;
   1243 	  this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
   1244 	  in .config
   1245 	* changed scan results data structure to include all information
   1246 	  elements to make it easier to support new IEs; old get_scan_result()
   1247 	  driver_ops is still supported for backwards compatibility (results
   1248 	  are converted internally to the new format), but all drivers should
   1249 	  start using the new get_scan_results2() to make them more likely to
   1250 	  work with new features
   1251 	* Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
   1252 	  application, i.e., it does not require Qt3Support anymore; Windows
   1253 	  binary of wpa_gui.exe is now from this directory and only requires
   1254 	  QtCore4.dll and QtGui4.dll libraries
   1255 	* updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
   1256 	  available as a separate package to make wpa_gui installation easier:
   1257 	  http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
   1258 	* added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
   1259 	  only shared key/password authentication is supported in this version
   1260 
   1261 2007-11-24 - v0.6.1
   1262 	* added support for configuring password as NtPasswordHash
   1263 	  (16-byte MD4 hash of password) in hash:<32 hex digits> format
   1264 	* added support for fallback from abbreviated TLS handshake to
   1265 	  full handshake when using EAP-FAST (e.g., due to an expired
   1266 	  PAC-Opaque)
   1267 	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
   1268 	  draft (draft-ietf-emu-eap-gpsk-07.txt)
   1269 	* added support for drivers that take care of RSN 4-way handshake
   1270 	  internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
   1271 	  WPA_ALG_PMK in set_key)
   1272 	* added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
   1273 	  .config); this version supports only ap_scan=2 mode and allow the
   1274 	  driver to take care of the 4-way handshake
   1275 	* fixed a buffer overflow in parsing TSF from scan results when using
   1276 	  driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
   1277 	  [Bug 232]
   1278 	* updated FT support to use the latest draft, IEEE 802.11r/D8.0
   1279 	* fixed an integer overflow issue in the ASN.1 parser used by the
   1280 	  (experimental) internal TLS implementation to avoid a potential
   1281 	  buffer read overflow
   1282 	* fixed a race condition with -W option (wait for a control interface
   1283 	  monitor before starting) that could have caused the first messages to
   1284 	  be lost
   1285 	* added support for processing TNCC-TNCS-Messages to report
   1286 	  recommendation (allow/none/isolate) when using TNC [Bug 243]
   1287 
   1288 2007-05-28 - v0.6.0
   1289 	* added network configuration parameter 'frequency' for setting
   1290 	  initial channel for IBSS (adhoc) networks
   1291 	* added experimental IEEE 802.11r/D6.0 support
   1292 	* updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
   1293 	* updated EAP-PSK to use the IANA-allocated EAP type 47
   1294 	* fixed EAP-PAX key derivation
   1295 	* fixed EAP-PSK bit ordering of the Flags field
   1296 	* fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
   1297 	  tunnelled identity request (previously, the identifier from the outer
   1298 	  method was used, not the tunnelled identifier which could be
   1299 	  different)
   1300 	* added support for fragmentation of outer TLS packets during Phase 2
   1301 	  of EAP-PEAP/TTLS/FAST
   1302 	* fixed EAP-TTLS AVP parser processing for too short AVP lengths
   1303 	* added support for EAP-FAST authentication with inner methods that
   1304 	  generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
   1305 	  for PAC provisioning)
   1306 	* added support for authenticated EAP-FAST provisioning
   1307 	* added support for configuring maximum number of EAP-FAST PACs to
   1308 	  store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
   1309 	* added support for storing EAP-FAST PACs in binary format
   1310 	  (fast_pac_format=binary in phase1 string)
   1311 	* fixed dbus ctrl_iface to validate message interface before
   1312 	  dispatching to avoid a possible segfault [Bug 190]
   1313 	* fixed PeerKey key derivation to use the correct PRF label
   1314 	* updated Windows binary build to link against OpenSSL 0.9.8d and
   1315 	  added support for EAP-FAST
   1316 	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
   1317 	  draft (draft-ietf-emu-eap-gpsk-04.txt)
   1318 	* fixed EAP-AKA Notification processing to allow Notification to be
   1319 	  processed after AKA Challenge response has been sent
   1320 	* updated to use IEEE 802.11w/D2.0 for management frame protection
   1321 	  (still experimental)
   1322 	* fixed EAP-TTLS implementation not to crash on use of freed memory
   1323 	  if TLS library initialization fails
   1324 	* added support for EAP-TNC (Trusted Network Connect)
   1325 	  (this version implements the EAP-TNC method and EAP-TTLS changes
   1326 	  needed to run two methods in sequence (IF-T) and the IF-IMC and
   1327 	  IF-TNCCS interfaces from TNCC)
   1328 
   1329 2006-11-24 - v0.5.6
   1330 	* added experimental, integrated TLSv1 client implementation with the
   1331 	  needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
   1332 	  setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
   1333 	  .config); this can be useful, e.g., if the target system does not
   1334 	  have a suitable TLS library and a minimal code size is required
   1335 	  (total size of this internal TLS/crypto code is bit under 50 kB on
   1336 	  x86 and the crypto code is shared by rest of the supplicant so some
   1337 	  of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
   1338 	* removed STAKey handshake since PeerKey handshake has replaced it in
   1339 	  IEEE 802.11ma and there are no known deployments of STAKey
   1340 	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
   1341 	  draft (draft-ietf-emu-eap-gpsk-01.txt)
   1342 	* added preliminary implementation of IEEE 802.11w/D1.0 (management
   1343 	  frame protection)
   1344 	  (Note: this requires driver support to work properly.)
   1345 	  (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
   1346 	* fixed Windows named pipes ctrl_iface to not stop listening for
   1347 	  commands if client program opens a named pipe and closes it
   1348 	  immediately without sending a command
   1349 	* fixed USIM PIN status determination for the case that PIN is not
   1350 	  needed (this allows EAP-AKA to be used with USIM cards that do not
   1351 	  use PIN)
   1352 	* added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
   1353 	  be used with cards that do not support file selection based on
   1354 	  partial AID
   1355 	* added support for matching the subjectAltName of the authentication
   1356 	  server certificate against multiple name components (e.g.,
   1357 	  altsubject_match="DNS:server.example.com;DNS:server2.example.com")
   1358 	* fixed EAP-SIM/AKA key derivation for re-authentication case (only
   1359 	  affects IEEE 802.1X with dynamic WEP keys)
   1360 	* changed ctrl_iface network configuration 'get' operations to not
   1361 	  return password/key material; if these fields are requested, "*"
   1362 	  will be returned if the password/key is set, but the value of the
   1363 	  parameter is not exposed
   1364 
   1365 2006-08-27 - v0.5.5
   1366 	* added support for building Windows version with UNICODE defined
   1367 	  (wide-char functions)
   1368 	* driver_ndis: fixed static WEP configuration to avoid race condition
   1369 	  issues with some NDIS drivers between association and setting WEP
   1370 	  keys
   1371 	* driver_ndis: added validation for IELength value in scan results to
   1372 	  avoid crashes when using buggy NDIS drivers [Bug 165]
   1373 	* fixed Release|Win32 target in the Visual Studio project files
   1374 	  (previously, only Debug|Win32 target was set properly)
   1375 	* changed control interface API call wpa_ctrl_pending() to allow it to
   1376 	  return -1 on error (e.g., connection lost); control interface clients
   1377 	  will need to make sure that they verify that the value is indeed >0
   1378 	  when determining whether there are pending messages
   1379 	* added an alternative control interface backend for Windows targets:
   1380 	  Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
   1381 	  control interface mechanism for Windows builds (previously, UDP to
   1382 	  localhost was used)
   1383 	* changed ctrl_interface configuration for UNIX domain sockets:
   1384 	  - deprecated ctrl_interface_group variable (it may be removed in
   1385 	    future versions)
   1386 	  - allow both directory and group be configured with ctrl_interface
   1387 	    in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
   1388 	  - ctrl_interface=/var/run/wpa_supplicant is still supported for the
   1389 	    case when group is not changed
   1390 	* added support for controlling more than one interface per process in
   1391 	  Windows version
   1392 	* added a workaround for a case where the AP is using unknown address
   1393 	  (e.g., MAC address of the wired interface) as the source address for
   1394 	  EAPOL-Key frames; previously, that source address was used as the
   1395 	  destination for EAPOL-Key frames and in key derivation; now, BSSID is
   1396 	  used even if the source address does not match with it
   1397 	  (this resolves an interoperability issue with Thomson SpeedTouch 580)
   1398 	* added a workaround for UDP-based control interface (which was used in
   1399 	  Windows builds before this release) to prevent packets with forged
   1400 	  addresses from being accepted as local control requests
   1401 	* removed ndis_events.cpp and possibility of using external
   1402 	  ndis_events.exe; C version (ndis_events.c) is fully functional and
   1403 	  there is no desire to maintain two separate versions of this
   1404 	  implementation
   1405 	* ndis_events: Changed NDIS event notification design to use WMI to
   1406 	  learn the adapter description through Win32_PnPEntity class; this
   1407 	  should fix some cases where the adapter name was not recognized
   1408 	  correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
   1409 	  USB) [Bug 113]
   1410 	* fixed selection of the first network in ap_scan=2 mode; previously,
   1411 	  wpa_supplicant could get stuck in SCANNING state when only the first
   1412 	  network for enabled (e.g., after 'wpa_cli select_network 0')
   1413 	* winsvc: added support for configuring ctrl_interface parameters in
   1414 	  registry (ctrl_interface string value in
   1415 	  HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
   1416 	  required to enable control interface (previously, this was hardcoded
   1417 	  to be enabled)
   1418 	* allow wpa_gui subdirectory to be built with both Qt3 and Qt4
   1419 	* converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
   1420 
   1421 2006-06-20 - v0.5.4
   1422 	* fixed build with CONFIG_STAKEY=y [Bug 143]
   1423 	* added support for doing MLME (IEEE 802.11 management frame
   1424 	  processing) in wpa_supplicant when using Devicescape IEEE 802.11
   1425 	  stack (wireless-dev.git tree)
   1426 	* added a new network block configuration option, fragment_size, to
   1427 	  configure the maximum EAP fragment size
   1428 	* driver_ndis: Disable WZC automatically for the selected interface to
   1429 	  avoid conflicts with two programs trying to control the radio; WZC
   1430 	  will be re-enabled (if it was enabled originally) when wpa_supplicant
   1431 	  is terminated
   1432 	* added an experimental TLSv1 client implementation
   1433 	  (CONFIG_TLS=internal) that can be used instead of an external TLS
   1434 	  library, e.g., to reduce total size requirement on systems that do
   1435 	  not include any TLS library by default (this is not yet complete;
   1436 	  basic functionality is there, but certificate validation is not yet
   1437 	  included)
   1438 	* added PeerKey handshake implementation for IEEE 802.11e
   1439 	  direct link setup (DLS) to replace STAKey handshake
   1440 	* fixed WPA PSK update through ctrl_iface for the case where the old
   1441 	  PSK was derived from an ASCII passphrase and the new PSK is set as
   1442 	  a raw PSK (hex string)
   1443 	* added new configuration option for identifying which network block
   1444 	  was used (id_str in wpa_supplicant.conf; included on
   1445 	  WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
   1446 	  variable in wpa_cli action scripts; in addition WPA_ID variable is
   1447 	  set to the current unique identifier that wpa_supplicant assigned
   1448 	  automatically for the network and that can be used with
   1449 	  GET_NETWORK/SET_NETWORK ctrl_iface commands)
   1450 	* wpa_cli action script is now called only when the connect/disconnect
   1451 	  status changes or when associating with a different network
   1452 	* fixed configuration parser not to remove CCMP from group cipher list
   1453 	  if WPA-None (adhoc) is used (pairwise=NONE in that case)
   1454 	* fixed integrated NDIS events processing not to hang the process due
   1455 	  to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
   1456 	* added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
   1457 	  draft-clancy-emu-eap-shared-secret-00.txt)
   1458 	* added Microsoft Visual Studio 2005 solution and project files for
   1459 	  build wpa_supplicant for Windows (see vs2005 subdirectory)
   1460 	* eloop_win: fixed unregistration of Windows events
   1461 	* l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
   1462 	  at the end of RSN pre-authentication and added unregistration of
   1463 	  a Windows event to avoid getting eloop_win stuck with an invalid
   1464 	  handle
   1465 	* driver_ndis: added support for selecting AP based on BSSID
   1466 	* added new environmental variable for wpa_cli action scripts:
   1467 	  WPA_CTRL_DIR is the current control interface directory
   1468 	* driver_ndis: added support for using NDISUIO instead of WinPcap for
   1469 	  OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
   1470 	  l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
   1471 	  wpa_supplicant without requiring WinPcap; note that using NDISUIO
   1472 	  requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
   1473 	  only one application to open the device
   1474 	* changed NDIS driver naming to only include device GUID, e.g.,
   1475 	  {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
   1476 	  specific \Device\NPF_ prefix before the GUID; the prefix is still
   1477 	  allowed for backwards compatibility, but it is not required anymore
   1478 	  when specifying the interface
   1479 	* driver_ndis: re-initialize driver interface is the adapter is removed
   1480 	  and re-inserted [Bug 159]
   1481 	* driver_madwifi: fixed TKIP and CCMP sequence number configuration on
   1482 	  big endian hosts [Bug 146]
   1483 
   1484 2006-04-27 - v0.5.3
   1485 	* fixed EAP-GTC response to include correct user identity when run as
   1486 	  phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
   1487 	* driver_ndis: Fixed encryption mode configuration for unencrypted
   1488 	  networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
   1489 	  refused to associate with open networks) [Bug 106]
   1490 	* driver_ndis: use BSSID OID polling to detect when IBSS network is
   1491 	  formed even when ndis_events code is included since some NDIS drivers
   1492 	  do not generate media connect events in IBSS mode
   1493 	* config_winreg: allow global ctrl_interface parameter to be configured
   1494 	  in Windows registry
   1495 	* config_winreg: added support for saving configuration data into
   1496 	  Windows registry
   1497 	* added support for controlling network device operational state
   1498 	  (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
   1499 	  http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
   1500 	  that can use this information)
   1501 	* driver_wext: added support for WE-21 change to SSID configuration
   1502 	* driver_wext: fixed privacy configuration for static WEP keys mode
   1503 	  [Bug 140]
   1504 	* added an optional driver_ops callback for MLME-SETPROTECTION.request
   1505 	  primitive
   1506 	* added support for EAP-SAKE (no EAP method number allocated yet, so
   1507 	  this is using the same experimental type 255 as EAP-PSK)
   1508 	* added support for dynamically loading EAP methods (.so files) instead
   1509 	  of requiring them to be statically linked in; this is disabled by
   1510 	  default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
   1511 	  on how to use this)
   1512 
   1513 2006-03-19 - v0.5.2
   1514 	* do not try to use USIM APDUs when initializing PC/SC for SIM card
   1515 	  access for a network that has not enabled EAP-AKA
   1516 	* fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
   1517 	  v0.5.1 due to the new support for expanded EAP types)
   1518 	* added support for generating EAP Expanded Nak
   1519 	* try to fetch scan results once before requesting new scan when
   1520 	  starting up in ap_scan=1 mode (this can speed up initial association
   1521 	  a lot with, e.g., madwifi-ng driver)
   1522 	* added support for receiving EAPOL frames from a Linux bridge
   1523 	  interface (-bbr0 on command line)
   1524 	* fixed EAPOL re-authentication for sessions that used PMKSA caching
   1525 	* changed EAP method registration to use a dynamic list of methods
   1526 	  instead of a static list generated at build time
   1527 	* fixed PMKSA cache deinitialization not to use freed memory when
   1528 	  removing PMKSA entries
   1529 	* fixed a memory leak in EAP-TTLS re-authentication
   1530 	* reject WPA/WPA2 message 3/4 if it does not include any valid
   1531 	  WPA/RSN IE
   1532 	* driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
   1533 	  if the driver does not support SIOCSIWAUTH
   1534 
   1535 2006-01-29 - v0.5.1
   1536 	* driver_test: added better support for multiple APs and STAs by using
   1537 	  a directory with sockets that include MAC address for each device in
   1538 	  the name (driver_param=test_dir=/tmp/test)
   1539 	* added support for EAP expanded type (vendor specific EAP methods)
   1540 	* added AP_SCAN command into ctrl_iface so that ap_scan configuration
   1541 	  option can be changed if needed
   1542 	* wpa_cli/wpa_gui: skip non-socket files in control directory when
   1543 	  using UNIX domain sockets; this avoids selecting an incorrect
   1544 	  interface (e.g., a PID file could be in this directory, even though
   1545 	  use of this directory for something else than socket files is not
   1546 	  recommended)
   1547 	* fixed TLS library deinitialization after RSN pre-authentication not
   1548 	  to disable TLS library for normal authentication
   1549 	* driver_wext: Remove null-termination from SSID length if the driver
   1550 	  used it; some Linux drivers do this and they were causing problems in
   1551 	  wpa_supplicant not finding matching configuration block. This change
   1552 	  would break a case where the SSID actually ends in '\0', but that is
   1553 	  not likely to happen in real use.
   1554 	* fixed PMKSA cache processing not to trigger deauthentication if the
   1555 	  current PMKSA cache entry is replaced with a valid new entry
   1556 	* fixed PC/SC initialization for ap_scan != 1 modes (this fixes
   1557 	  EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
   1558 	  ap_scan=2)
   1559 
   1560 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
   1561 	* added experimental STAKey handshake implementation for IEEE 802.11e
   1562 	  direct link setup (DLS); note: this is disabled by default in both
   1563 	  build and runtime configuration (can be enabled with CONFIG_STAKEY=y
   1564 	  and stakey=1)
   1565 	* fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
   1566 	  decrypt AT_ENCR_DATA attributes correctly
   1567 	* fixed EAP-AKA to allow resynchronization within the same session
   1568 	* made code closer to ANSI C89 standard to make it easier to port to
   1569 	  other C libraries and compilers
   1570 	* started moving operating system or C library specific functions into
   1571 	  wrapper functions defined in os.h and implemented in os_*.c to make
   1572 	  code more portable
   1573 	* wpa_supplicant can now be built with Microsoft Visual C++
   1574 	  (e.g., with the freely available Toolkit 2003 version or Visual
   1575 	  C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
   1576 	  example makefile for nmake
   1577 	* added support for using Windows registry for command line parameters
   1578 	  (CONFIG_MAIN=main_winsvc) and configuration data
   1579 	  (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
   1580 	  contents; this version can be run both as a Windows service and as a
   1581 	  normal application; 'wpasvc.exe app' to start as applicant,
   1582 	  'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
   1583 	  'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
   1584 	  unregister a service
   1585 	* made it possible to link ndis_events.exe functionality into
   1586 	  wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
   1587 	* added better support for multiple control interface backends
   1588 	  (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
   1589 	* fixed PC/SC code to use correct length for GSM AUTH command buffer
   1590 	  and to not use pioRecvPci with SCardTransmit() calls; these were not
   1591 	  causing visible problems with pcsc-lite, but Windows Winscard.dll
   1592 	  refused the previously used parameters; this fixes EAP-SIM and
   1593 	  EAP-AKA authentication using SIM/USIM card under Windows
   1594 	* added new event loop implementation for Windows using
   1595 	  WaitForMultipleObject() instead of select() in order to allow waiting
   1596 	  for non-socket objects; this can be selected with
   1597 	  CONFIG_ELOOP=eloop_win in .config
   1598 	* added support for selecting l2_packet implementation in .config
   1599 	  (CONFIG_L2_PACKET; following options are available now: linux, pcap,
   1600 	  winpcap, freebsd, none)
   1601 	* added new l2_packet implementation for WinPcap
   1602 	  (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
   1603 	  reduce latency in EAPOL receive processing from about 100 ms to about
   1604 	  3 ms
   1605 	* added support for EAP-FAST key derivation using other ciphers than
   1606 	  RC4-128-SHA for authentication and AES128-SHA for provisioning
   1607 	* added support for configuring CA certificate as DER file and as a
   1608 	  configuration blob
   1609 	* fixed private key configuration as configuration blob and added
   1610 	  support for using PKCS#12 as a blob
   1611 	* tls_gnutls: added support for using PKCS#12 files; added support for
   1612 	  session resumption
   1613 	* added support for loading trusted CA certificates from Windows
   1614 	  certificate store: ca_cert="cert_store://<name>", where <name> is
   1615 	  likely CA (Intermediate CA certificates) or ROOT (root certificates)
   1616 	* added C version of ndis_events.cpp and made it possible to build this
   1617 	  with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
   1618 	  easily on cross-compilation builds
   1619 	* added wpasvc.exe into Windows binary release; this is an alternative
   1620 	  version of wpa_supplicant.exe with configuration backend using
   1621 	  Windows registry and with the entry point designed to run as a
   1622 	  Windows service
   1623 	* integrated ndis_events.exe functionality into wpa_supplicant.exe and
   1624 	  wpasvc.exe and removed this additional tool from the Windows binary
   1625 	  release since it is not needed anymore
   1626 	* load winscard.dll functions dynamically when building with MinGW
   1627 	  since MinGW does not yet include winscard library
   1628 
   1629 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
   1630 	* l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
   1631 	  and WinPcap to receive frames sent to PAE group address
   1632 	* disable EAP state machine when IEEE 802.1X authentication is not used
   1633 	  in order to get rid of bogus "EAP failed" messages
   1634 	* fixed OpenSSL error reporting to go through all pending errors to
   1635 	  avoid confusing reports of old errors being reported at later point
   1636 	  during handshake
   1637 	* fixed configuration file updating to not write empty variables
   1638 	  (e.g., proto or key_mgmt) that the file parser would not accept
   1639 	* fixed ADD_NETWORK ctrl_iface command to use the same default values
   1640 	  for variables as empty network definitions read from config file
   1641 	  would get
   1642 	* fixed EAP state machine to not discard EAP-Failure messages in many
   1643 	  cases (e.g., during TLS handshake)
   1644 	* fixed a infinite loop in private key reading if the configured file
   1645 	  cannot be parsed successfully
   1646 	* driver_madwifi: added support for madwifi-ng
   1647 	* wpa_gui: do not display password/PSK field contents
   1648 	* wpa_gui: added CA certificate configuration
   1649 	* driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
   1650 	* driver_ndis: include Beacon IEs in AssocInfo in order to notice if
   1651 	  the new AP is using different WPA/RSN IE
   1652 	* use longer timeout for IEEE 802.11 association to avoid problems with
   1653 	  drivers that may take more than five second to associate
   1654 
   1655 2005-10-27 - v0.4.6
   1656 	* allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
   1657 	  RSN IE, but WPA IE would match with wpa_supplicant configuration
   1658 	* added support for named configuration blobs in order to avoid having
   1659 	  to use file system for external files (e.g., certificates);
   1660 	  variables can be set to "blob://<blob name>" instead of file path to
   1661 	  use a named blob; supported fields: pac_file, client_cert,
   1662 	  private_key
   1663 	* fixed RSN pre-authentication (it was broken in the clean up of WPA
   1664 	  state machine interface in v0.4.5)
   1665 	* driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
   1666 	  sure the driver configures broadcast decryption correctly
   1667 	* added ca_path (and ca_path2) configuration variables that can be used
   1668 	  to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
   1669 	  system-wide trusted CA list
   1670 	* added support for starting wpa_supplicant without a configuration
   1671 	  file (-C argument must be used to set ctrl_interface parameter for
   1672 	  this case; in addition, -p argument can be used to provide
   1673 	  driver_param; these new arguments can also be used with a
   1674 	  configuration to override the values from the configuration)
   1675 	* added global control interface that can be optionally used for adding
   1676 	  and removing network interfaces dynamically (-g command line argument
   1677 	  for both wpa_supplicant and wpa_cli) without having to restart
   1678 	  wpa_supplicant process
   1679 	* wpa_gui:
   1680 	  - try to save configuration whenever something is modified
   1681 	  - added WEP key configuration
   1682 	  - added possibility to edit the current network configuration
   1683 	* driver_ndis: fixed driver polling not to increase frequency on each
   1684 	  received EAPOL frame due to incorrectly cancelled timeout
   1685 	* added simple configuration file examples (in examples subdirectory)
   1686 	* fixed driver_wext.c to filter wireless events based on ifindex to
   1687 	  avoid interfaces receiving events from other interfaces
   1688 	* delay sending initial EAPOL-Start couple of seconds to speed up
   1689 	  authentication for the most common case of Authenticator starting
   1690 	  EAP authentication immediately after association
   1691 
   1692 2005-09-25 - v0.4.5
   1693 	* added a workaround for clearing keys with ndiswrapper to allow
   1694 	  roaming from WPA enabled AP to plaintext one
   1695 	* added docbook documentation (doc/docbook) that can be used to
   1696 	  generate, e.g., man pages
   1697 	* l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
   1698 	  PF_PACKET in order to prepare for network devices that do not use
   1699 	  Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
   1700 	* use receipt of EAPOL-Key frame as a lower layer success indication
   1701 	  for EAP state machine to allow recovery from dropped EAP-Success
   1702 	  frame
   1703 	* cleaned up internal EAPOL frame processing by not including link
   1704 	  layer (Ethernet) header during WPA and EAPOL/EAP processing; this
   1705 	  header is added only when transmitted the frame; this makes it easier
   1706 	  to use wpa_supplicant on link layers that use different header than
   1707 	  Ethernet
   1708 	* updated EAP-PSK to use draft 9 by default since this can now be
   1709 	  tested with hostapd; removed support for draft 3, including
   1710 	  server_nai configuration option from network blocks
   1711 	* driver_wired: add PAE address to the multicast address list in order
   1712 	  to be able to receive EAPOL frames with drivers that do not include
   1713 	  these multicast addresses by default
   1714 	* driver_wext: add support for WE-19
   1715 	* added support for multiple configuration backends (CONFIG_BACKEND
   1716 	  option); currently, only 'file' is supported (i.e., the format used
   1717 	  in wpa_supplicant.conf)
   1718 	* added support for updating configuration ('wpa_cli save_config');
   1719 	  this is disabled by default and can be enabled with global
   1720 	  update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
   1721 	  and wpa_gui to store the configuration changes in a permanent store
   1722 	* added GET_NETWORK ctrl_iface command
   1723 	  (e.g., 'wpa_cli get_network 0 ssid')
   1724 
   1725 2005-08-21 - v0.4.4
   1726 	* replaced OpenSSL patch for EAP-FAST support
   1727 	  (openssl-tls-extensions.patch) with a more generic and correct
   1728 	  patch (the new patch is not compatible with the previous one, so the
   1729 	  OpenSSL library will need to be patched with the new patch in order
   1730 	  to be able to build wpa_supplicant with EAP-FAST support)
   1731 	* added support for using Windows certificate store (through CryptoAPI)
   1732 	  for client certificate and private key operations (EAP-TLS)
   1733 	  (see wpa_supplicant.conf for more information on how to configure
   1734 	  this with private_key)
   1735 	* ported wpa_gui to Windows
   1736 	* added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
   1737 	  built with the open source version of the Qt4 for Windows
   1738 	* allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
   1739 	  with drivers that do not support WPA
   1740 	* ndis_events: fixed Windows 2000 support
   1741 	* added support for enabling/disabling networks from the list of all
   1742 	  configured networks ('wpa_cli enable_network <network id>' and
   1743 	  'wpa_cli disable_network <network id>')
   1744 	* added support for adding and removing network from the current
   1745 	  configuration ('wpa_cli add_network' and 'wpa_cli remove_network
   1746 	  <network id>'); added networks are disabled by default and they can
   1747 	  be enabled with enable_network command once the configuration is done
   1748 	  for the new network; note: configuration file is not yet updated, so
   1749 	  these new networks are lost when wpa_supplicant is restarted
   1750 	* added support for setting network configuration parameters through
   1751 	  the control interface, for example:
   1752 	  wpa_cli set_network 0 ssid "\"my network\""
   1753 	* fixed parsing of strings that include both " and # within double
   1754 	  quoted area (e.g., "start"#end")
   1755 	* added EAP workaround for PEAP session resumption: allow outer,
   1756 	  i.e., not tunneled, EAP-Success to terminate session since; this can
   1757 	  be disabled with eap_workaround=0
   1758 	  (this was allowed for PEAPv1 before, but now it is also allowed for
   1759 	  PEAPv0 since at least one RADIUS authentication server seems to be
   1760 	  doing this for PEAPv0, too)
   1761 	* wpa_gui: added preliminary support for adding new networks to the
   1762 	  wpa_supplicant configuration (double click on the scan results to
   1763 	  open network configuration)
   1764 
   1765 2005-06-26 - v0.4.3
   1766 	* removed interface for external EAPOL/EAP supplicant (e.g.,
   1767 	  Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
   1768 	  anymore and is unlikely to be used by anyone
   1769 	* driver_ndis: fixed WinPcap 3.0 support
   1770 	* fixed build with CONFIG_DNET_PCAP=y on Linux
   1771 	* l2_packet: moved different implementations into separate files
   1772 	  (l2_packet_*.c)
   1773 
   1774 2005-06-12 - v0.4.2
   1775 	* driver_ipw: updated driver structures to match with ipw2200-1.0.4
   1776 	  (note: ipw2100-1.1.0 is likely to require an update to work with
   1777 	  this)
   1778 	* added support for using ap_scan=2 mode with multiple network blocks;
   1779 	  wpa_supplicant will go through the networks one by one until the
   1780 	  driver reports a successful association; this uses the same order for
   1781 	  networks as scan_ssid=1 scans, i.e., the priority field is ignored
   1782 	  and the network block order in the file is used instead
   1783 	* fixed a potential issue in RSN pre-authentication ending up using
   1784 	  freed memory if pre-authentication times out
   1785 	* added support for matching alternative subject name extensions of the
   1786 	  authentication server certificate; new configuration variables
   1787 	  altsubject_match and altsubject_match2
   1788 	* driver_ndis: added support for IEEE 802.1X authentication with wired
   1789 	  NDIS drivers
   1790 	* added support for querying private key password (EAP-TLS) through the
   1791 	  control interface (wpa_cli/wpa_gui) if one is not included in the
   1792 	  configuration file
   1793 	* driver_broadcom: fixed couple of memory leaks in scan result
   1794 	  processing
   1795 	* EAP-PAX is now registered as EAP type 46
   1796 	* fixed EAP-PAX MAC calculation
   1797 	* fixed EAP-PAX CK and ICK key derivation
   1798 	* added support for using password with EAP-PAX (as an alternative to
   1799 	  entering key with eappsk); SHA-1 hash of the password will be used as
   1800 	  the key in this case
   1801 	* added support for arbitrary driver interface parameters through the
   1802 	  configuration file with a new driver_param field; this adds a new
   1803 	  driver_ops function set_param()
   1804 	* added possibility to override l2_packet module with driver interface
   1805 	  API (new send_eapol handler); this can be used to implement driver
   1806 	  specific TX/RX functions for EAPOL frames
   1807 	* fixed ctrl_interface_group processing for the case where gid is
   1808 	  entered as a number, not group name
   1809 	* driver_test: added support for testing hostapd with wpa_supplicant
   1810 	  by using test driver interface without any kernel drivers or network
   1811 	  cards
   1812 
   1813 2005-05-22 - v0.4.1
   1814 	* driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
   1815 	  packets to be encrypted; this was apparently broken by the changed
   1816 	  ioctl order in v0.4.0
   1817 	* driver_madwifi: added preliminary support for compiling against 'BSD'
   1818 	  branch of madwifi CVS tree
   1819 	* added support for EAP-MSCHAPv2 password retries within the same EAP
   1820 	  authentication session
   1821 	* added support for password changes with EAP-MSCHAPv2 (used when the
   1822 	  password has expired)
   1823 	* added support for reading additional certificates from PKCS#12 files
   1824 	  and adding them to the certificate chain
   1825 	* fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
   1826 	  were used
   1827 	* fixed a possible double free in EAP-TTLS fast-reauthentication when
   1828 	  identity or password is entered through control interface
   1829 	* display EAP Notification messages to user through control interface
   1830 	  with "CTRL-EVENT-EAP-NOTIFICATION" prefix
   1831 	* added GUI version of wpa_cli, wpa_gui; this is not build
   1832 	  automatically with 'make'; use 'make wpa_gui' to build (this requires
   1833 	  Qt development tools)
   1834 	* added 'disconnect' command to control interface for setting
   1835 	  wpa_supplicant in state where it will not associate before
   1836 	  'reassociate' command has been used
   1837 	* added support for selecting a network from the list of all configured
   1838 	  networks ('wpa_cli select_network <network id>'; this disabled all
   1839 	  other networks; to re-enable, 'wpa_cli select_network any')
   1840 	* added support for getting scan results through control interface
   1841 	* added EAP workaround for PEAPv1 session resumption: allow outer,
   1842 	  i.e., not tunneled, EAP-Success to terminate session since; this can
   1843 	  be disabled with eap_workaround=0
   1844 
   1845 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
   1846 	* added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
   1847 	  used to reduce the size of the wpa_supplicant considerably if
   1848 	  debugging code is not needed
   1849 	* fixed EAPOL-Key validation to drop packets with invalid Key Data
   1850 	  Length; such frames could have crashed wpa_supplicant due to buffer
   1851 	  overflow
   1852 	* added support for wired authentication (IEEE 802.1X on wired
   1853 	  Ethernet); driver interface 'wired'
   1854 	* obsoleted set_wpa() handler in the driver interface API (it can be
   1855 	  replaced by moving enable/disable functionality into init()/deinit())
   1856 	  (calls to set_wpa() are still present for backwards compatibility,
   1857 	  but they may be removed in the future)
   1858 	* driver_madwifi: fixed association in plaintext mode
   1859 	* modified the EAP workaround that accepts EAP-Success with incorrect
   1860 	  Identifier to be even less strict about verification in order to
   1861 	  interoperate with some authentication servers
   1862 	* added support for sending TLS alerts
   1863 	* added support for 'any' SSID wildcard; if ssid is not configured or
   1864 	  is set to an empty string, any SSID will be accepted for non-WPA AP
   1865 	* added support for asking PIN (for SIM) from frontends (e.g.,
   1866 	  wpa_cli); if a PIN is needed, but not included in the configuration
   1867 	  file, a control interface request is sent and EAP processing is
   1868 	  delayed until the PIN is available
   1869 	* added support for using external devices (e.g., a smartcard) for
   1870 	  private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
   1871 	  new wpa_supplicant.conf variables:
   1872 	  - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
   1873 	  - network: engine, engine_id, key_id
   1874 	* added experimental support for EAP-PAX
   1875 	* added monitor mode for wpa_cli (-a<path to a program to run>) that
   1876 	  allows external commands (e.g., shell scripts) to be run based on
   1877 	  wpa_supplicant events, e.g., when authentication has been completed
   1878 	  and data connection is ready; other related wpa_cli arguments:
   1879 	  -B (run in background), -P (write PID file); wpa_supplicant has a new
   1880 	  command line argument (-W) that can be used to make it wait until a
   1881 	  control interface command is received in order to avoid missing
   1882 	  events
   1883 	* added support for opportunistic WPA2 PMKSA key caching (disabled by
   1884 	  default, can be enabled with proactive_key_caching=1)
   1885 	* fixed RSN IE in 4-Way Handshake message 2/4 for the case where
   1886 	  Authenticator rejects PMKSA caching attempt and the driver is not
   1887 	  using assoc_info events
   1888 	* added -P<pid file> argument for wpa_supplicant to write the current
   1889 	  process id into a file
   1890 
   1891 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
   1892 	* added new phase1 option parameter, include_tls_length=1, to force
   1893 	  wpa_supplicant to add TLS Message Length field to all TLS messages
   1894 	  even if the packet is not fragmented; this may be needed with some
   1895 	  authentication servers
   1896 	* fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
   1897 	  using drivers that take care of AP selection (e.g., when using
   1898 	  ap_scan=2)
   1899 	* fixed reprocessing of pending request after ctrl_iface requests for
   1900 	  identity/password/otp
   1901 	* fixed ctrl_iface requests for identity/password/otp in Phase 2 of
   1902 	  EAP-PEAP and EAP-TTLS
   1903 	* all drivers using driver_wext: set interface up and select Managed
   1904 	  mode when starting wpa_supplicant; set interface down when exiting
   1905 	* renamed driver_ipw2100.c to driver_ipw.c since it now supports both
   1906 	  ipw2100 and ipw2200; please note that this also changed the
   1907 	  configuration variable in .config to CONFIG_DRIVER_IPW
   1908 
   1909 2005-01-24 - v0.3.6
   1910 	* fixed a busy loop introduced in v0.3.5 for scan result processing
   1911 	  when no matching AP is found
   1912 
   1913 2005-01-23 - v0.3.5
   1914 	* added a workaround for an interoperability issue with a Cisco AP
   1915 	  when using WPA2-PSK
   1916 	* fixed non-WPA IEEE 802.1X to use the same authentication timeout as
   1917 	  WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
   1918 	  retransmission of dropped frames)
   1919 	* fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
   1920 	  (e.g., segfault when processing EAPOL-Key frames)
   1921 	* fixed EAP workaround and fast reauthentication configuration for
   1922 	  RSN pre-authentication; previously these were disabled and
   1923 	  pre-authentication would fail if the used authentication server
   1924 	  requires EAP workarounds
   1925 	* added support for blacklisting APs that fail or timeout
   1926 	  authentication in ap_scan=1 mode so that all APs are tried in cases
   1927 	  where the ones with strongest signal level are failing authentication
   1928 	* fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
   1929 	  authentication attempt
   1930 	* allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
   1931 	  in the previous authentication (previously, only Phase 1 success was
   1932 	  verified)
   1933 
   1934 2005-01-09 - v0.3.4
   1935 	* added preliminary support for IBSS (ad-hoc) mode configuration
   1936 	  (mode=1 in network block); this included a new key_mgmt mode
   1937 	  WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
   1938 	  key management; see wpa_supplicant.conf for more details and an
   1939 	  example on how to configure this (note: this is currently implemented
   1940 	  only for driver_hostapd.c, but the changes should be trivial to add
   1941 	  in associate() handler for other drivers, too (assuming the driver
   1942 	  supports WPA-None)
   1943 	* added preliminary port for native Windows (i.e., no cygwin) using
   1944 	  mingw
   1945 
   1946 2005-01-02 - v0.3.3
   1947 	* added optional support for GNU Readline and History Libraries for
   1948 	  wpa_cli (CONFIG_READLINE)
   1949 	* cleaned up EAP state machine <-> method interface and number of
   1950 	  small problems with error case processing not terminating on
   1951 	  EAP-Failure but waiting for timeout
   1952 	* added couple of workarounds for interoperability issues with a
   1953 	  Cisco AP when using WPA2
   1954 	* added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
   1955 	  Note: This requires a patch for openssl to add support for TLS
   1956 	  extensions and number of workarounds for operations without
   1957 	  certificates. Proof of concept type of experimental patch is
   1958 	  included in openssl-tls-extensions.patch.
   1959 
   1960 2004-12-19 - v0.3.2
   1961 	* fixed private key loading for cases where passphrase is not set
   1962 	* fixed Windows/cygwin L2 packet handler freeing; previous version
   1963 	  could cause a segfault when RSN pre-authentication was completed
   1964 	* added support for PMKSA caching with drivers that generate RSN IEs
   1965 	  (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
   1966 	  but similar code can be easily added to driver_ndiswrapper.c once
   1967 	  ndiswrapper gets full support for RSN PMKSA caching
   1968 	* improved recovery from PMKID mismatches by requesting full EAP
   1969 	  authentication in case of failed PMKSA caching attempt
   1970 	* driver_ndis: added support for NDIS NdisMIncidateStatus() events
   1971 	  (this requires that ndis_events is ran while wpa_supplicant is
   1972 	  running)
   1973 	* driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
   1974 	* added support for driver interfaces to replace the interface name
   1975 	  based on driver/OS specific mapping, e.g., in case of driver_ndis,
   1976 	  this allows the beginning of the adapter description to be used as
   1977 	  the interface name
   1978 	* added support for CR+LF (Windows-style) line ends in configuration
   1979 	  file
   1980 	* driver_ndis: enable radio before starting scanning, disable radio
   1981 	  when exiting
   1982 	* modified association event handler to set portEnabled = FALSE before
   1983 	  clearing port Valid in order to reset EAP state machine and avoid
   1984 	  problems with new authentication getting ignored because of state
   1985 	  machines ending up in AUTHENTICATED/SUCCESS state based on old
   1986 	  information
   1987 	* added support for driver events to add PMKID candidates in order to
   1988 	  allow drivers to give priority to most likely roaming candidates
   1989 	* driver_hostap: moved PrivacyInvoked configuration to associate()
   1990 	  function so that this will not be set for plaintext connections
   1991 	* added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
   1992 	  interface can distinguish plaintext and IEEE 802.1X (no WPA)
   1993 	  authentication
   1994 	* fixed static WEP key configuration to use broadcast/default type for
   1995 	  all keys (previously, the default TX key was configured as pairwise/
   1996 	  unicast key)
   1997 	* driver_ndis: added legacy WPA capability detection for non-WPA2
   1998 	  drivers
   1999 	* added support for setting static WEP keys for IEEE 802.1X without
   2000 	  dynamic WEP keying (eapol_flags=0)
   2001 
   2002 2004-12-12 - v0.3.1
   2003 	* added support for reading PKCS#12 (PFX) files (as a replacement for
   2004 	  PEM/DER) to get certificate and private key (CONFIG_PKCS12)
   2005 	* fixed compilation with CONFIG_PCSC=y
   2006 	* added new ap_scan mode, ap_scan=2, for drivers that take care of
   2007 	  association, but need to be configured with security policy and SSID,
   2008 	  e.g., ndiswrapper and NDIS driver; this mode should allow such
   2009 	  drivers to work with hidden SSIDs and optimized roaming; when
   2010 	  ap_scan=2 is used, only the first network block in the configuration
   2011 	  file is used and this configuration should have explicit security
   2012 	  policy (i.e., only one option in the lists) for key_mgmt, pairwise,
   2013 	  group, proto variables
   2014 	* added experimental port of wpa_supplicant for Windows
   2015 	  - driver_ndis.c driver interface (NDIS OIDs)
   2016 	  - currently, this requires cygwin and WinPcap
   2017 	  - small utility, win_if_list, can be used to get interface name
   2018 	* control interface can now be removed at build time; add
   2019 	  CONFIG_CTRL_IFACE=y to .config to maintain old functionality
   2020 	* optional Xsupplicant interface can now be removed at build time;
   2021 	  (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
   2022 	* added auth_alg to driver interface associate() parameters to make it
   2023 	  easier for drivers to configure authentication algorithm as part of
   2024 	  the association
   2025 
   2026 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
   2027 	* driver_broadcom: added new driver interface for Broadcom wl.o driver
   2028 	  (a generic driver for Broadcom IEEE 802.11a/g cards)
   2029 	* wpa_cli: fixed parsing of -p <path> command line argument
   2030 	* PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
   2031 	  ACK, not tunneled EAP-Success (of which only the first byte was
   2032 	  actually send due to a bug in previous code); this seems to
   2033 	  interoperate with most RADIUS servers that implements PEAPv1
   2034 	* PEAPv1: added support for terminating PEAP authentication on tunneled
   2035 	  EAP-Success message; this can be configured by adding
   2036 	  peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
   2037 	  (some RADIUS servers require this whereas others require a tunneled
   2038 	  reply
   2039 	* PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
   2040 	  the old label for key derivation; previously, the default was 1,
   2041 	  but it looks like most existing PEAPv1 implementations use the old
   2042 	  label which is thus more suitable default option
   2043 	* added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
   2044 	* fixed parsing of wep_tx_keyidx
   2045 	* added support for configuring list of allowed Phase 2 EAP types
   2046 	  (for both EAP-PEAP and EAP-TTLS) instead of only one type
   2047 	* added support for configuring IEEE 802.11 authentication algorithm
   2048 	  (auth_alg; mainly for using Shared Key authentication with static
   2049 	  WEP keys)
   2050 	* added support for EAP-AKA (with UMTS SIM)
   2051 	* fixed couple of errors in PCSC handling that could have caused
   2052 	  random-looking errors for EAP-SIM
   2053 	* added support for EAP-SIM pseudonyms and fast re-authentication
   2054 	* added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
   2055 	  session resumption)
   2056 	* added support for EAP-SIM with two challanges
   2057 	  (phase1="sim_min_num_chal=3" can be used to require three challenges)
   2058 	* added support for configuring DH/DSA parameters for an ephemeral DH
   2059 	  key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
   2060 	  dh_file and dh_file2 (phase 2); this adds support for using DSA keys
   2061 	  and optional DH key exchange to achieve forward secracy with RSA keys
   2062 	* added support for matching subject of the authentication server
   2063 	  certificate with a substring when using EAP-TLS/PEAP/TTLS; new
   2064 	  configuration variables subject_match and subject_match2
   2065 	* changed SSID configuration in driver_wext.c (used by many driver
   2066 	  interfaces) to use ssid_len+1 as the length for SSID since some Linux
   2067 	  drivers expect this
   2068 	* fixed couple of unaligned reads in scan result parsing to fix WPA
   2069 	  connection on some platforms (e.g., ARM)
   2070 	* added driver interface for Intel ipw2100 driver
   2071 	* added support for LEAP with WPA
   2072 	* added support for larger scan results report (old limit was 4 kB of
   2073 	  data, i.e., about 35 or so APs) when using Linux wireless extensions
   2074 	  v17 or newer
   2075 	* fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
   2076 	  only if there is a PMKSA cache entry for the current AP
   2077 	* fixed error handling for case where reading of scan results fails:
   2078 	  must schedule a new scan or wpa_supplicant will remain waiting
   2079 	  forever
   2080 	* changed debug output to remove shared password/key material by
   2081 	  default; all key information can be included with -K command line
   2082 	  argument to match the previous behavior
   2083 	* added support for timestamping debug log messages (disabled by
   2084 	  default, can be enabled with -t command line argument)
   2085 	* set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
   2086 	  if keys are not configured to be used; this fixes IEEE 802.1X mode
   2087 	  with drivers that use this information to configure whether Privacy
   2088 	  bit can be in Beacon frames (e.g., ndiswrapper)
   2089 	* avoid clearing driver keys if no keys have been configured since last
   2090 	  key clear request; this seems to improve reliability of group key
   2091 	  handshake for ndiswrapper & NDIS driver which seems to be suffering
   2092 	  of some kind of timing issue when the keys are cleared again after
   2093 	  association
   2094 	* changed driver interface API:
   2095 	  - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
   2096 	    version is being used (now, this is set to 2; previously, it was
   2097 	    not defined)
   2098 	  - pass pointer to private data structure to all calls
   2099 	  - the new API is not backwards compatible; all in-tree driver
   2100 	    interfaces has been converted to the new API
   2101 	* added support for controlling multiple interfaces (radios) per
   2102 	  wpa_supplicant process; each interface needs to be listed on the
   2103 	  command line (-c, -i, -D arguments) with -N as a separator
   2104 	  (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
   2105 	* added a workaround for EAP servers that incorrectly use same Id for
   2106 	  sequential EAP packets
   2107 	* changed libpcap/libdnet configuration to use .config variable,
   2108 	  CONFIG_DNET_PCAP, instead of requiring Makefile modification
   2109 	* improved downgrade attack detection in IE verification of msg 3/4:
   2110 	  verify both WPA and RSN IEs, if present, not only the selected one;
   2111 	  reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
   2112 	  Probe Response frame, and RSN is enabled in wpa_supplicant
   2113 	  configuration
   2114 	* fixed WPA msg 3/4 processing to allow Key Data field contain other
   2115 	  IEs than just one WPA IE
   2116 	* added support for FreeBSD and driver interface for the BSD net80211
   2117 	  layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
   2118 	  required kernel mods have not yet been committed
   2119 	* made EAP workarounds configurable; enabled by default, can be
   2120 	  disabled with network block option eap_workaround=0
   2121 
   2122 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
   2123 	* resolved couple of interoperability issues with EAP-PEAPv1 and
   2124 	  Phase 2 (inner EAP) fragment reassembly
   2125 	* driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
   2126 	  AP is using non-zero key index for the unicast key and key index zero
   2127 	  for the broadcast key
   2128 	* driver_hostap: fixed IEEE 802.1X WEP key updates and
   2129 	  re-authentication by allowing unencrypted EAPOL frames when not using
   2130 	  WPA
   2131 	* added a new driver interface, 'wext', which uses only standard,
   2132 	  driver independent functionality in Linux wireless extensions;
   2133 	  currently, this can be used only for non-WPA IEEE 802.1X mode, but
   2134 	  eventually, this is to be extended to support full WPA/WPA2 once
   2135 	  Linux wireless extensions get support for this
   2136 	* added support for mode in which the driver is responsible for AP
   2137 	  scanning and selection; this is disabled by default and can be
   2138 	  enabled with global ap_scan=0 variable in wpa_supplicant.conf;
   2139 	  this mode can be used, e.g., with generic 'wext' driver interface to
   2140 	  use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
   2141 	  supporting wireless extensions.
   2142 	* driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
   2143 	  operation with an AP that does not include SSID in the Beacon frames)
   2144 	* added support for new EAP authentication methods:
   2145 	  EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
   2146 	* added support for asking one-time-passwords from frontends (e.g.,
   2147 	  wpa_cli); this 'otp' command works otherwise like 'password' command,
   2148 	  but the password is used only once and the frontend will be asked for
   2149 	  a new password whenever a request from authenticator requires a
   2150 	  password; this can be used with both EAP-OTP and EAP-GTC
   2151 	* changed wpa_cli to automatically re-establish connection so that it
   2152 	  does not need to be re-started when wpa_supplicant is terminated and
   2153 	  started again
   2154 	* improved user data (identity/password/otp) requests through
   2155 	  frontends: process pending EAPOL packets after getting new
   2156 	  information so that full authentication does not need to be
   2157 	  restarted; in addition, send pending requests again whenever a new
   2158 	  frontend is attached
   2159 	* changed control frontends to use a new directory for socket files to
   2160 	  make it easier for wpa_cli to automatically select between interfaces
   2161 	  and to provide access control for the control interface;
   2162 	  wpa_supplicant.conf: ctrl_interface is now a path
   2163 	  (/var/run/wpa_supplicant is the recommended path) and
   2164 	  ctrl_interface_group can be used to select which group gets access to
   2165 	  the control interface;
   2166 	  wpa_cli: by default, try to connect to the first interface available
   2167 	  in /var/run/wpa_supplicant; this path can be overriden with -p option
   2168 	  and an interface can be selected with -i option (i.e., in most common
   2169 	  cases, wpa_cli does not need to get any arguments)
   2170 	* added support for LEAP
   2171 	* added driver interface for Linux ndiswrapper
   2172 	* added priority option for network blocks in the configuration file;
   2173 	  this allows networks to be grouped based on priority (the scan
   2174 	  results are searched for matches with network blocks in this order)
   2175 
   2176 2004-06-20 - v0.2.3
   2177 	* sort scan results to improve AP selection
   2178 	* fixed control interface socket removal for some error cases
   2179 	* improved scan requesting and authentication timeout
   2180 	* small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
   2181 	  TLS processing
   2182 	* PEAP version can now be forced with phase1="peapver=<ver>"
   2183 	  (mostly for testing; by default, the highest version supported by
   2184 	  both the Supplicant and Authentication Server is selected
   2185 	  automatically)
   2186 	* added support for madwifi driver (Atheros ar521x)
   2187 	* added a workaround for cases where AP sets Install Tx/Rx bit for
   2188 	  WPA Group Key messages when pairwise keys are used (without this,
   2189 	  the Group Key would be used for Tx and the AP would drop frames
   2190 	  from the station)
   2191 	* added GSM SIM/USIM interface for GSM authentication algorithm for
   2192 	  EAP-SIM; this requires pcsc-lite
   2193 	* added support for ATMEL AT76C5XXx driver
   2194 	* fixed IEEE 802.1X WEP key derivation in the case where Authenticator
   2195 	  does not include key data in the EAPOL-Key frame (i.e., part of
   2196 	  EAP keying material is used as data encryption key)
   2197 	* added support for using plaintext and static WEP networks
   2198 	  (key_mgmt=NONE)
   2199 
   2200 2004-05-31 - v0.2.2
   2201 	* added support for new EAP authentication methods:
   2202 	  EAP-TTLS/EAP-MD5-Challenge
   2203 	  EAP-TTLS/EAP-GTC
   2204 	  EAP-TTLS/EAP-MSCHAPv2
   2205 	  EAP-TTLS/EAP-TLS
   2206 	  EAP-TTLS/MSCHAPv2
   2207 	  EAP-TTLS/MSCHAP
   2208 	  EAP-TTLS/PAP
   2209 	  EAP-TTLS/CHAP
   2210 	  EAP-PEAP/TLS
   2211 	  EAP-PEAP/GTC
   2212 	  EAP-PEAP/MD5-Challenge
   2213 	  EAP-GTC
   2214 	  EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
   2215 	* added support for anonymous identity (to be used when identity is
   2216 	  sent in plaintext; real identity will be used within TLS protected
   2217 	  tunnel (e.g., with EAP-TTLS)
   2218 	* added event messages from wpa_supplicant to frontends, e.g., wpa_cli
   2219 	* added support for requesting identity and password information using
   2220 	  control interface; in other words, the password for EAP-PEAP or
   2221 	  EAP-TTLS does not need to be included in the configuration file since
   2222 	  a frontand (e.g., wpa_cli) can ask it from the user
   2223 	* improved RSN pre-authentication to use a candidate list and process
   2224 	  all candidates from each scan; not only one per scan
   2225 	* fixed RSN IE and WPA IE capabilities field parsing
   2226 	* ignore Tx bit in GTK IE when Pairwise keys are used
   2227 	* avoid making new scan requests during IEEE 802.1X negotiation
   2228 	* use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
   2229 	  with TLS support (this replaces the included implementation with
   2230 	  library code to save about 8 kB since the library code is needed
   2231 	  anyway for TLS)
   2232 	* fixed WPA-PSK only mode when compiled without IEEE 802.1X support
   2233 	  (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
   2234 
   2235 2004-05-06 - v0.2.1
   2236 	* added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
   2237 	  Supplicant
   2238 	  - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
   2239 	  - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
   2240 	  - EAP-MD5 (cannot be used with WPA-RADIUS)
   2241 	    [draft-ietf-eap-rfc2284bis-09.txt]
   2242 	  - EAP-TLS [RFC 2716]
   2243 	  - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
   2244 	  - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
   2245 	    [draft-kamath-pppext-eap-mschapv2-00.txt]
   2246 	    (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
   2247 	    default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
   2248 	  - new configuration file options: eap, identity, password, ca_cert,
   2249 	    client_cert, privatekey, private_key_passwd
   2250 	  - Xsupplicant is not required anymore, but it can be used by
   2251 	    disabling the internal IEEE 802.1X Supplicant with -e command line
   2252 	    option
   2253 	  - this code is not included in the default build; Makefile need to
   2254 	    be edited for this (uncomment lines for selected functionality)
   2255 	  - EAP-TLS and EAP-PEAP require openssl libraries
   2256 	* use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
   2257 	* added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
   2258 	  (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
   2259 	   EAPOL-Key frames instead of WPA key handshakes)
   2260 	* added support for IEEE 802.11i/RSN (WPA2)
   2261 	  - improved PTK Key Handshake
   2262 	  - PMKSA caching, pre-authentication
   2263 	* fixed wpa_supplicant to ignore possible extra data after WPA
   2264 	  EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
   2265 	  TPTK' error from message 3 of 4-Way Handshake in case the AP
   2266 	  includes extra data after the EAPOL-Key)
   2267 	* added interface for external programs (frontends) to control
   2268 	  wpa_supplicant
   2269 	  - CLI example (wpa_cli) with interactive mode and command line
   2270 	    mode
   2271 	  - replaced SIGUSR1 status/statistics with the new control interface
   2272 	* made some feature compile time configurable
   2273 	  - .config file for make
   2274 	  - driver interfaces (hostap, hermes, ..)
   2275 	  - EAPOL/EAP functions
   2276 
   2277 2004-02-15 - v0.2.0
   2278 	* Initial version of wpa_supplicant
   2279
