Disabled by default, enable by 624 config option disassoc_low_ack. 625 * nl80211: 626 - Support GTK rekey offload. 627 - Support PMKSA candidate events. This adds support for RSN 628 pre-authentication with nl80211 interface and drivers that handle 629 roaming internally. 630 * dbus: 631 - Add a DBus signal for EAP SM requests, emitted on the Interface 632 object. 633 - Export max scan ssids supported by the driver as MaxScanSSID. 634 - Add signal Certification for information about server certification. 635 - Add BSSExpireAge and BSSExpireCount interface properties and 636 support set/get, which allows for setting BSS cache expiration age 637 and expiration scan count. 638 - Add ConfigFile to AddInterface properties. 639 - Add Interface.Country property and support to get/set the value. 640 - Add DBus property CurrentAuthMode. 641 - P2P DBus API added. 642 - Emit property changed events (for property BSSs) when adding/ 643 removing BSSs. 644 - Treat '' in SSIDs of Interface.Scan as a request for broadcast 645 scan, instead of ignoring it. 646 - Add DBus getter/setter for FastReauth. 647 - Raise PropertiesChanged on org.freedesktop.DBus.Properties. 648 * wpa_cli: 649 - Send AP-STA-DISCONNECTED event when an AP disconnects a station 650 due to inactivity. 651 - Make second argument to set command optional. This can be used to 652 indicate a zero length value. 653 - Add signal_poll command. 654 - Add bss_expire_age and bss_expire_count commands to set/get BSS 655 cache expiration age and expiration scan count. 656 - Add ability to set scan interval (the time in seconds wpa_s waits 657 before requesting a new scan after failing to find a suitable 658 network in scan results) using scan_interval command. 659 - Add event CTRL-EVENT-ASSOC-REJECT for association rejected. 660 - Add command get version, that returns wpa_supplicant version string. 661 - Add command sta_autoconnect for disabling automatic reconnection 662 on receiving disconnection event. 663 - Setting bssid parameter to an empty string "" or any can now be 664 used to clear the bssid_set flag in a network block, i.e., to remove 665 bssid filtering. 666 - Add tdls_testing command to add a special testing feature for 667 changing TDLS behavior. Build param CONFIG_TDLS_TESTING must be 668 enabled as well. 669 - For interworking, add wpa_cli commands interworking_select, 670 interworking_connect, anqp_get, fetch_anqp, and stop_fetch_anqp. 671 - Many P2P commands were added. See README-P2P. 672 - Many WPS/WPS ER commands - see WPS/WPS ER sections for details. 673 - Allow set command to change global config parameters. 674 - Add log_level command, which can be used to display the current 675 debugging level and to change the log level during run time. 676 - Add note command, which can be used to insert notes to the debug 677 log. 678 - Add internal line edit implementation. CONFIG_WPA_CLI_EDIT=y 679 can now be used to build wpa_cli with internal implementation of 680 line editing and history support. This can be used as a replacement 681 for CONFIG_READLINE=y. 682 * AP mode: Add max_num_sta config option, which can be used to limit 683 the number of stations allowed to connect to the AP. 684 * Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad 685 config file. 686 * wext: Increase scan timeout from 5 to 10 seconds. 687 * Add blacklist command, allowing an external program to 688 manage the BSS blacklist and display its current contents. 689 * WPS: 690 - Add wpa_cli wps_pin get command for generating random PINs. This can 691 be used in a UI to generate a PIN without starting WPS (or P2P) 692 operation. 693 - Set RF bands based on driver capabilities, instead of hardcoding 694 them. 695 - Add mechanism for indicating non-standard WPS errors. 696 - Add CONFIG_WPS_REG_DISABLE_OPEN=y option to disable open networks 697 by default. 698 - Add wps_ap_pin cli command for wpa_supplicant AP mode. 699 - Add wps_check_pin cli command for processing PIN from user input. 700 UIs can use this command to process a PIN entered by a user and to 701 validate the checksum digit (if present). 702 - Cancel WPS operation on PBC session overlap detection. 703 - New wps_cancel command in wpa_cli will cancel a pending WPS 704 operation. 705 - wpa_cli action: Add WPS_EVENT_SUCCESS and WPS_EVENT_FAIL handlers. 706 - Trigger WPS config update on Manufacturer, Model Name, Model 707 Number, and Serial Number changes. 708 - Fragment size is now configurable for EAP-WSC peer.

Slow down attacks on 711 failures up to 10. 712 - Allow AP to start in Enrollee mode without AP PIN for probing, to 713 be compatible with Windows 7. 714 - Add Config Error into WPS-FAIL events to provide more info to the 715 user on how to resolve the issue. 716 - Label and Display config methods are not allowed to be enabled 717 at the same time, since it is unclear which PIN to use if both 718 methods are advertised. 719 - When controlling multiple interfaces: 720 - apply WPS commands to all interfaces configured to use WPS 721 - apply WPS config changes to all interfaces that use WPS 722 - when an attack is detected on any interface, disable AP PIN on 723 all interfaces 724 * WPS ER: 725 - Add special AP Setup Locked mode to allow read only ER. 726 ap_setup_locked=2 can now be used to enable a special mode where 727 WPS ER can learn the current AP settings, but cannot change them. 728 - Show SetSelectedRegistrar events as ctrl_iface events 729 - Add wps_er_set_config to enroll a network based on a local 730 network configuration block instead of having to (re-)learn the 731 current AP settings with wps_er_learn. 732 - Allow AP filtering based on IP address, add ctrl_iface event for 733 learned AP settings, add wps_er_config command to configure an AP. 734 * WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2) 735 - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool 736 for testing protocol extensibility. 737 - Add build option CONFIG_WPS_STRICT to allow disabling of WPS 738 workarounds. 739 - Add support for AuthorizedMACs attribute. 740 * TDLS: 741 - Propogate TDLS related nl80211 capability flags from kernel and 742 add them as driver capability flags. If the driver doesn't support 743 capabilities, assume TDLS is supported internally. When TDLS is 744 explicitly not supported, disable all user facing TDLS operations. 745 - Allow TDLS to be disabled at runtime (mostly for testing). 746 Use set tdls_disabled. 747 - Honor AP TDLS settings that prohibit/allow TDLS. 748 - Add a special testing feature for changing TDLS behavior. Use 749 CONFIG_TDLS_TESTING build param to enable. Configure at runtime 750 with tdls_testing cli command. 751 - Add support for TDLS 802.11z. 752 * wlantest: Add a tool wlantest for IEEE802.11 protocol testing. 753 wlantest can be used to capture frames from a monitor interface 754 for realtime capturing or from pcap files for offline analysis. 755 * Interworking: Support added for 802.11u. Enable in .config with 756 CONFIG_INTERWORKING. See wpa_supplicant.conf for config parameters 757 for interworking. wpa_cli commands added to support this are 758 interworking_select, interworking_connect, anqp_get, fetch_anqp, 759 and stop_fetch_anqp. 760 * Android: Add build and runtime support for Android wpa_supplicant. 761 * bgscan learn: Add new bgscan that learns BSS information based on 762 previous scans, and uses that information to dynamically generate 763 the list of channels for background scans. 764 * Add a new debug message level for excessive information. Use 765 -ddd to enable. 766 * TLS: Add support for tls_disable_time_checks=1 in client mode. 767 * Internal TLS: 768 - Add support for TLS v1.1 (RFC 4346). Enable with build parameter 769 CONFIG_TLSV11. 770 - Add domainComponent parser for X.509 names. 771 * Linux: Add RFKill support by adding an interface state "disabled". 772 * Reorder some IEs to get closer to IEEE 802.11 standard. Move 773 WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames. 774 Move HT IEs to be later in (Re)Assoc Resp. 775 * Solaris: Add support for wired 802.1X client. 776 * Wi-Fi Direct support. See README-P2P for more information. 777 * Many bugfixes. 778 779 2010-04-18 - v0.7.2 780 * nl80211: fixed number of issues with roaming 781 * avoid unnecessary roaming if multiple APs with similar signal 782 strength are present in scan results 783 * add TLS client events and server probing to ease design of 784 automatic detection of EAP parameters 785 * add option for server certificate matching (SHA256 hash of the 786 certificate) instead of trusted CA certificate configuration 787 * bsd: Cleaned up driver wrapper and added various low-level 788 configuration options 789 * wpa_gui-qt4: do not show too frequent WPS AP available events as 790 tray messages 791 * TNC: fixed issues with fragmentation 792 * EAP-TNC: add Flags field into fragment acknowledgement (needed to 793 interoperate with other implementations; may potentially breaks 794 compatibility with older wpa_supplicant/hostapd versions) 795 * wpa_cli: added option for using a separate process to receive event 796 messages to reduce latency in showing these 797 (CFLAGS += -DCONFIG_WPA_CLI_FORK=y in .config to enable this) 798 * maximum BSS table size can now be configured (bss_max_count) 799 * BSSes to be included in the BSS table can be filtered based on 800 configured SSIDs to save memory (filter_ssids) 801 * fix number of issues with IEEE 802.11r/FT; this version is not 802 backwards compatible with old versions 803 * nl80211: add support for IEEE 802.11r/FT protocol (both over-the-air 804 and over-the-DS) 805 * add freq_list network configuration parameter to allow the AP 806 selection to filter out entries based on the operating channel 807 * add signal strength change events for bgscan; this allows more 808 dynamic changes to background scanning interval based on changes in 809 the signal strength with the current AP; this improves roaming within 810 ESS quite a bit, e.g., with bgscan="simple:30:-45:300" in the network 811 configuration block to request background scans less frequently when 812 signal strength remains good and to automatically trigger background 813 scans whenever signal strength drops noticeably 814 (this is currently only available with nl80211) 815 * add BSSID and reason code (if available) to disconnect event messages 816 * wpa_gui-qt4: more complete support for translating the GUI with 817 linguist and add German translation 818 * fix DH padding with internal crypto code (mainly, for WPS) 819 * do not trigger initial scan automatically anymore if there are no 820 enabled networks 821 822 2010-01-16 - v0.7.1 823 * cleaned up driver wrapper API (struct wpa_driver_ops); the new API 824 is not fully backwards compatible, so out-of-tree driver wrappers 825 will need modifications 826 * cleaned up various module interfaces 827 * merge hostapd and wpa_supplicant developers' documentation into a 828 single document 829 * nl80211: use explicit deauthentication to clear cfg80211 state to 830 avoid issues when roaming between APs 831 * dbus: major design changes in the new D-Bus API 832 (fi.w1.wpa_supplicant1) 833 * nl80211: added support for IBSS networks 834 * added internal debugging mechanism with backtrace support and memory 835 allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y) 836 * added WPS ER unsubscription command to more cleanly unregister from 837 receiving UPnP events when ER is terminated 838 * cleaned up AP mode operations to avoid need for virtual driver_ops 839 wrapper 840 * added BSS table to maintain more complete scan result information 841 over multiple scans (that may include only partial results) 842 * wpa_gui-qt4: update Peers dialog information more dynamically while 843 the dialog is kept open 844 * fixed PKCS#12 use with OpenSSL 1.0.0 845 * driver_wext: Added cfg80211-specific optimization to avoid some 846 unnecessary scans and to speed up association 847 848 2009-11-21 - v0.7.0 849 * increased wpa_cli ping interval to 5 seconds and made this 850 configurable with a new command line options (-G<seconds>) 851 * fixed scan buffer processing with WEXT to handle up to 65535 852 byte result buffer (previously, limited to 32768 bytes) 853 * allow multiple driver wrappers to be specified on command line 854 (e.g., -Dnl80211,wext); the first one that is able to initialize the 855 interface will be used 856 * added support for multiple SSIDs per scan request to optimize 857 scan_ssid=1 operations in ap_scan=1 mode (i.e., search for hidden 858 SSIDs); this requires driver support and can currently be used only 859 with nl80211 860 * added support for WPS USBA out-of-band mechanism with USB Flash 861 Drives (UFD) (CONFIG_WPS_UFD=y) 862 * driver_ndis: add PAE group address to the multicast address list to 863 fix wired IEEE 802.1X authentication 864 * fixed IEEE 802.11r key derivation function to match with the standard 865 (note: this breaks interoperability with previous version) [Bug 303] 866 * added better support for drivers that allow separate authentication 867 and association commands (e.g., mac80211-based Linux drivers with 868 nl80211; SME in wpa_supplicant); this allows over-the-air FT protocol 869 to be used (IEEE 802.11r) 870 * fixed SHA-256 based key derivation function to match with the 871 standard when using CCMP (for IEEE 802.11r and IEEE 802.11w) 872 (note: this breaks interoperability with previous version) [Bug 307] 873 * use shared driver wrapper files with hostapd 874 * added AP mode functionality (CONFIG_AP=y) with mode=2 in the network 875 block; this can be used for open and WPA2-Personal networks 876 (optionally, with WPS); this links in parts of hostapd functionality 877 into wpa_supplicant 878 * wpa_gui-qt4: added new Peers dialog to show information about peers 879 (other devices, including APs and stations, etc. in the neighborhood) 880 * added support for WPS External Registrar functionality (configure APs 881 and enroll new devices); can be used with wpa_gui-qt4 Peers dialog 882 and wpa_cli commands wps_er_start, wps_er_stop, wps_er_pin, 883 wps_er_pbc, wps_er_learn 884 (this can also be used with a new 'none' driver wrapper if no 885 wireless device or IEEE 802.1X on wired is needed) 886 * driver_nl80211: multiple updates to provide support for new Linux 887 nl80211/mac80211 functionality 888 * updated management frame protection to use IEEE Std 802.11w-2009 889 * fixed number of small WPS issues and added workarounds to 890 interoperate with common deployed broken implementations 891 * added support for NFC out-of-band mechanism with WPS 892 * driver_ndis: fixed wired IEEE 802.1X authentication with PAE group 893 address frames 894 * added preliminary support for IEEE 802.11r RIC processing 895 * added support for specifying subset of enabled frequencies to scan 896 (scan_freq option in the network configuration block); this can speed 897 up scanning process considerably if it is known that only a small 898 subset of channels is actually used in the network (this is currently 899 supported only with -Dnl80211) 900 * added a workaround for race condition between receiving the 901 association event and the following EAPOL-Key 902 * added background scan and roaming infrastructure to allow 903 network-specific optimizations to be used to improve roaming within 904 an ESS (same SSID) 905 * added new DBus interface (fi.w1.wpa_supplicant1) 906 907 2009-01-06 - v0.6.7 908 * added support for Wi-Fi Protected Setup (WPS) 909 (wpa_supplicant can now be configured to act as a WPS Enrollee to 910 enroll credentials for a network using PIN and PBC methods; in 911 addition, wpa_supplicant can act as a wireless WPS Registrar to 912 configure an AP); WPS support can be enabled by adding CONFIG_WPS=y 913 into .config and setting the runtime configuration variables in 914 wpa_supplicant.conf (see WPS section in the example configuration 915 file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to 916 manage WPS negotiation; see README-WPS for more details 917 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf) 918 * added support for using driver_test over UDP socket 919 * fixed PEAPv0 Cryptobinding interoperability issue with Windows Server 920 2008 NPS; optional cryptobinding is now enabled (again) by default 921 * fixed PSK editing in wpa_gui 922 * changed EAP-GPSK to use the IANA assigned EAP method type 51 923 * added a Windows installer that includes WinPcap and all the needed 924 DLLs; in addition, it set up the registry automatically so that user 925 will only need start wpa_gui to get prompted to start the wpasvc 926 servide and add a new interface if needed through wpa_gui dialog 927 * updated management frame protection to use IEEE 802.11w/D7.0 928 929 2008-11-23 - v0.6.6 930 * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA 931 (can be used to simulate test SIM/USIM card with a known private key; 932 enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config 933 and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration) 934 * added a new network configuration option, wpa_ptk_rekey, that can be 935 used to enforce frequent PTK rekeying, e.g., to mitigate some attacks 936 against TKIP deficiencies 937 * added an optional mitigation mechanism for certain attacks against 938 TKIP by delaying Michael MIC error reports by a random amount of time 939 between 0 and 60 seconds; this can be enabled with a build option 940 CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config 941 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits, 942 not bytes 943 * updated OpenSSL code for EAP-FAST to use an updated version of the 944 session ticket overriding API that was included into the upstream 945 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is 946 needed with that version anymore) 947 * updated userspace MLME instructions to match with the current Linux 948 mac80211 implementation; please also note that this can only be used 949 with driver_nl80211.c (the old code from driver_wext.c was removed) 950 * added support (Linux only) for RoboSwitch chipsets (often found in 951 consumer grade routers); driver interface 'roboswitch' 952 * fixed canceling of PMKSA caching when using drivers that generate 953 RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know 954 about 955 956 2008-11-01 - v0.6.5 957 * added support for SHA-256 as X.509 certificate digest when using the 958 internal X.509/TLSv1 implementation 959 * updated management frame protection to use IEEE 802.11w/D6.0 960 * added support for using SHA256-based stronger key derivation for WPA2 961 (IEEE 802.11w) 962 * fixed FT (IEEE 802.11r) authentication after a failed association to 963 use correct FTIE 964 * added support for configuring Phase 2 (inner/tunneled) authentication 965 method with wpa_gui-qt4 966 967 2008-08-10 - v0.6.4 968 * added support for EAP Sequences in EAP-FAST Phase 2 969 * added support for using TNC with EAP-FAST 970 * added driver_ps3 for the PS3 Linux wireless driver 971 * added support for optional cryptobinding with PEAPv0 972 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to 973 allow fallback to full handshake if server rejects PAC-Opaque 974 * added fragmentation support for EAP-TNC 975 * added support for parsing PKCS #8 formatted private keys into the 976 internal TLS implementation (both PKCS #1 RSA key and PKCS #8 977 encapsulated RSA key can now be used) 978 * added option of using faster, but larger, routines in the internal 979 LibTomMath (for internal TLS implementation) to speed up DH and RSA 980 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y) 981 * fixed race condition between disassociation event and group key 982 handshake to avoid getting stuck in incorrect state [Bug 261] 983 * fixed opportunistic key caching (proactive_key_caching) 984 985 2008-02-22 - v0.6.3 986 * removed 'nai' and 'eappsk' network configuration variables that were 987 previously used for configuring user identity and key for EAP-PSK, 988 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the 989 replacement for 'nai' (if old configuration used a separate 990 'identity' value, that would now be configured as 991 'anonymous_identity'). 'password' field is now used as the 992 replacement for 'eappsk' (it can also be set using hexstring to 993 present random binary data) 994 * removed '-w' command line parameter (wait for interface to be added, 995 if needed); cleaner way of handling this functionality is to use an 996 external mechanism (e.g., hotplug scripts) that start wpa_supplicant 997 when an interface is added 998 * updated FT support to use the latest draft, IEEE 802.11r/D9.0 999 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for 1000 indicating when new scan results become available 1001 * added new ctrl_iface command, BSS, to allow scan results to be 1002 fetched without hitting the message size limits (this command 1003 can be used to iterate through the scan results one BSS at the time) 1004 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION 1005 attributes in EAP-SIM Start/Response when using fast reauthentication 1006 * fixed EAPOL not to end up in infinite loop when processing dynamic 1007 WEP keys with IEEE 802.1X 1008 * fixed problems in getting NDIS events from WMI on Windows 2000 1009 1010 2008-01-01 - v0.6.2 1011 * added support for Makefile builds to include debug-log-to-a-file 1012 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line) 1013 * fixed EAP-SIM and EAP-AKA message parser to validate attribute 1014 lengths properly to avoid potential crash caused by invalid messages 1015 * added data structure for storing allocated buffers (struct wpabuf); 1016 this does not affect wpa_supplicant usage, but many of the APIs 1017 changed and various interfaces (e.g., EAP) is not compatible with old 1018 versions 1019 * added support for protecting EAP-AKA/Identity messages with 1020 AT_CHECKCODE (optional feature in RFC 4187) 1021 * added support for protected result indication with AT_RESULT_IND for 1022 EAP-SIM and EAP-AKA (phase1="result_ind=1") 1023 * added driver_wext workaround for race condition between scanning and 1024 association with drivers that take very long time to scan all 1025 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now 1026 using a longer hardcoded timeout for the scan if the driver supports 1027 notifications for scan completion (SIOCGIWSCAN event); this helps, 1028 e.g., in cases where wpa_supplicant and madwifi driver ended up in 1029 loop where the driver did not even try to associate 1030 * stop EAPOL timer tick when no timers are in use in order to reduce 1031 power consumption (no need to wake up the process once per second) 1032 [Bug 237] 1033 * added support for privilege separation (run only minimal part of 1034 wpa_supplicant functionality as root and rest as unprivileged, 1035 non-root process); see 'Privilege separation' in README for details; 1036 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y 1037 in .config 1038 * changed scan results data structure to include all information 1039 elements to make it easier to support new IEs; old get_scan_result() 1040 driver_ops is still supported for backwards compatibility (results 1041 are converted internally to the new format), but all drivers should 1042 start using the new get_scan_results2() to make them more likely to 1043 work with new features 1044 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4 1045 application, i.e., it does not require Qt3Support anymore; Windows 1046 binary of wpa_gui.exe is now from this directory and only requires 1047 QtCore4.dll and QtGui4.dll libraries 1048 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs 1049 available as a separate package to make wpa_gui installation easier: 1050 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip 1051 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt); 1052 only shared key/password authentication is supported in this version 1053 1054 2007-11-24 - v0.6.1 1055 * added support for configuring password as NtPasswordHash 1056 (16-byte MD4 hash of password) in hash:<32 hex digits> format 1057 * added support for fallback from abbreviated TLS handshake to 1058 full handshake when using EAP-FAST (e.g., due to an expired 1059 PAC-Opaque) 1060 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 1061 draft (draft-ietf-emu-eap-gpsk-07.txt) 1062 * added support for drivers that take care of RSN 4-way handshake 1063 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and 1064 WPA_ALG_PMK in set_key) 1065 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in 1066 .config); this version supports only ap_scan=2 mode and allow the 1067 driver to take care of the 4-way handshake 1068 * fixed a buffer overflow in parsing TSF from scan results when using 1069 driver_wext.c with a driver that includes the TSF (e.g., iwl4965) 1070 [Bug 232] 1071 * updated FT support to use the latest draft, IEEE 802.11r/D8.0 1072 * fixed an integer overflow issue in the ASN.1 parser used by the 1073 (experimental) internal TLS implementation to avoid a potential 1074 buffer read overflow 1075 * fixed a race condition with -W option (wait for a control interface 1076 monitor before starting) that could have caused the first messages to 1077 be lost 1078 * added support for processing TNCC-TNCS-Messages to report 1079 recommendation (allow/none/isolate) when using TNC [Bug 243] 1080 1081 2007-05-28 - v0.6.0 1082 * added network configuration parameter 'frequency' for setting 1083 initial channel for IBSS (adhoc) networks 1084 * added experimental IEEE 802.11r/D6.0 support 1085 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48 1086 * updated EAP-PSK to use the IANA-allocated EAP type 47 1087 * fixed EAP-PAX key derivation 1088 * fixed EAP-PSK bit ordering of the Flags field 1089 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in 1090 tunnelled identity request (previously, the identifier from the outer 1091 method was used, not the tunnelled identifier which could be 1092 different) 1093 * added support for fragmentation of outer TLS packets during Phase 2 1094 of EAP-PEAP/TTLS/FAST 1095 * fixed EAP-TTLS AVP parser processing for too short AVP lengths 1096 * added support for EAP-FAST authentication with inner methods that 1097 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported 1098 for PAC provisioning) 1099 * added support for authenticated EAP-FAST provisioning 1100 * added support for configuring maximum number of EAP-FAST PACs to 1101 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string) 1102 * added support for storing EAP-FAST PACs in binary format 1103 (fast_pac_format=binary in phase1 string) 1104 * fixed dbus ctrl_iface to validate message interface before 1105 dispatching to avoid a possible segfault [Bug 190] 1106 * fixed PeerKey key derivation to use the correct PRF label 1107 * updated Windows binary build to link against OpenSSL 0.9.8d and 1108 added support for EAP-FAST 1109 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 1110 draft (draft-ietf-emu-eap-gpsk-04.txt) 1111 * fixed EAP-AKA Notification processing to allow Notification to be 1112 processed after AKA Challenge response has been sent 1113 * updated to use IEEE 802.11w/D2.0 for management frame protection 1114 (still experimental) 1115 * fixed EAP-TTLS implementation not to crash on use of freed memory 1116 if TLS library initialization fails 1117 * added support for EAP-TNC (Trusted Network Connect) 1118 (this version implements the EAP-TNC method and EAP-TTLS changes 1119 needed to run two methods in sequence (IF-T) and the IF-IMC and 1120 IF-TNCCS interfaces from TNCC) 1121 1122 2006-11-24 - v0.5.6 1123 * added experimental, integrated TLSv1 client implementation with the 1124 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by 1125 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in 1126 .config); this can be useful, e.g., if the target system does not 1127 have a suitable TLS library and a minimal code size is required 1128 (total size of this internal TLS/crypto code is bit under 50 kB on 1129 x86 and the crypto code is shared by rest of the supplicant so some 1130 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB) 1131 * removed STAKey handshake since PeerKey handshake has replaced it in 1132 IEEE 802.11ma and there are no known deployments of STAKey 1133 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 1134 draft (draft-ietf-emu-eap-gpsk-01.txt) 1135 * added preliminary implementation of IEEE 802.11w/D1.0 (management 1136 frame protection) 1137 (Note: this requires driver support to work properly.) 1138 (Note2: IEEE 802.11w is an unapproved draft and subject to change.) 1139 * fixed Windows named pipes ctrl_iface to not stop listening for 1140 commands if client program opens a named pipe and closes it 1141 immediately without sending a command 1142 * fixed USIM PIN status determination for the case that PIN is not 1143 needed (this allows EAP-AKA to be used with USIM cards that do not 1144 use PIN) 1145 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to 1146 be used with cards that do not support file selection based on 1147 partial AID 1148 * added support for matching the subjectAltName of the authentication 1149 server certificate against multiple name components (e.g., 1150 altsubject_match="DNS:server.example.com;DNS:server2.example.com") 1151 * fixed EAP-SIM/AKA key derivation for re-authentication case (only 1152 affects IEEE 802.1X with dynamic WEP keys) 1153 * changed ctrl_iface network configuration 'get' operations to not 1154 return password/key material; if these fields are requested, "*" 1155 will be returned if the password/key is set, but the value of the 1156 parameter is not exposed 1157 1158 2006-08-27 - v0.5.5 1159 * added support for building Windows version with UNICODE defined 1160 (wide-char functions) 1161 * driver_ndis: fixed static WEP configuration to avoid race condition 1162 issues with some NDIS drivers between association and setting WEP 1163 keys 1164 * driver_ndis: added validation for IELength value in scan results to 1165 avoid crashes when using buggy NDIS drivers [Bug 165] 1166 * fixed Release|Win32 target in the Visual Studio project files 1167 (previously, only Debug|Win32 target was set properly) 1168 * changed control interface API call wpa_ctrl_pending() to allow it to 1169 return -1 on error (e.g., connection lost); control interface clients 1170 will need to make sure that they verify that the value is indeed >0 1171 when determining whether there are pending messages 1172 * added an alternative control interface backend for Windows targets: 1173 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default 1174 control interface mechanism for Windows builds (previously, UDP to 1175 localhost was used) 1176 * changed ctrl_interface configuration for UNIX domain sockets: 1177 - deprecated ctrl_interface_group variable (it may be removed in 1178 future versions) 1179 - allow both directory and group be configured with ctrl_interface 1180 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel 1181 - ctrl_interface=/var/run/wpa_supplicant is still supported for the 1182 case when group is not changed 1183 * added support for controlling more than one interface per process in 1184 Windows version 1185 * added a workaround for a case where the AP is using unknown address 1186 (e.g., MAC address of the wired interface) as the source address for 1187 EAPOL-Key frames; previously, that source address was used as the 1188 destination for EAPOL-Key frames and in key derivation; now, BSSID is 1189 used even if the source address does not match with it 1190 (this resolves an interoperability issue with Thomson SpeedTouch 580) 1191 * added a workaround for UDP-based control interface (which was used in 1192 Windows builds before this release) to prevent packets with forged 1193 addresses from being accepted as local control requests 1194 * removed ndis_events.cpp and possibility of using external 1195 ndis_events.exe; C version (ndis_events.c) is fully functional and 1196 there is no desire to maintain two separate versions of this 1197 implementation 1198 * ndis_events: Changed NDIS event notification design to use WMI to 1199 learn the adapter description through Win32_PnPEntity class; this 1200 should fix some cases where the adapter name was not recognized 1201 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500 1202 USB) [Bug 113] 1203 * fixed selection of the first network in ap_scan=2 mode; previously, 1204 wpa_supplicant could get stuck in SCANNING state when only the first 1205 network for enabled (e.g., after 'wpa_cli select_network 0') 1206 * winsvc: added support for configuring ctrl_interface parameters in 1207 registry (ctrl_interface string value in 1208 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is 1209 required to enable control interface (previously, this was hardcoded 1210 to be enabled) 1211 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4 1212 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format 1213 1214 2006-06-20 - v0.5.4 1215 * fixed build with CONFIG_STAKEY=y [Bug 143] 1216 * added support for doing MLME (IEEE 802.11 management frame 1217 processing) in wpa_supplicant when using Devicescape IEEE 802.11 1218 stack (wireless-dev.git tree) 1219 * added a new network block configuration option, fragment_size, to 1220 configure the maximum EAP fragment size 1221 * driver_ndis: Disable WZC automatically for the selected interface to 1222 avoid conflicts with two programs trying to control the radio; WZC 1223 will be re-enabled (if it was enabled originally) when wpa_supplicant 1224 is terminated 1225 * added an experimental TLSv1 client implementation 1226 (CONFIG_TLS=internal) that can be used instead of an external TLS 1227 library, e.g., to reduce total size requirement on systems that do 1228 not include any TLS library by default (this is not yet complete; 1229 basic functionality is there, but certificate validation is not yet 1230 included) 1231 * added PeerKey handshake implementation for IEEE 802.11e 1232 direct link setup (DLS) to replace STAKey handshake 1233 * fixed WPA PSK update through ctrl_iface for the case where the old 1234 PSK was derived from an ASCII passphrase and the new PSK is set as 1235 a raw PSK (hex string) 1236 * added new configuration option for identifying which network block 1237 was used (id_str in wpa_supplicant.conf; included on 1238 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental 1239 variable in wpa_cli action scripts; in addition WPA_ID variable is 1240 set to the current unique identifier that wpa_supplicant assigned 1241 automatically for the network and that can be used with 1242 GET_NETWORK/SET_NETWORK ctrl_iface commands) 1243 * wpa_cli action script is now called only when the connect/disconnect 1244 status changes or when associating with a different network 1245 * fixed configuration parser not to remove CCMP from group cipher list 1246 if WPA-None (adhoc) is used (pairwise=NONE in that case) 1247 * fixed integrated NDIS events processing not to hang the process due 1248 to a missed change in eloop_win.c API in v0.5.3 [Bug 155] 1249 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK, 1250 draft-clancy-emu-eap-shared-secret-00.txt) 1251 * added Microsoft Visual Studio 2005 solution and project files for 1252 build wpa_supplicant for Windows (see vs2005 subdirectory) 1253 * eloop_win: fixed unregistration of Windows events 1254 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet 1255 at the end of RSN pre-authentication and added unregistration of 1256 a Windows event to avoid getting eloop_win stuck with an invalid 1257 handle 1258 * driver_ndis: added support for selecting AP based on BSSID 1259 * added new environmental variable for wpa_cli action scripts: 1260 WPA_CTRL_DIR is the current control interface directory 1261 * driver_ndis: added support for using NDISUIO instead of WinPcap for 1262 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new 1263 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build 1264 wpa_supplicant without requiring WinPcap; note that using NDISUIO 1265 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows 1266 only one application to open the device 1267 * changed NDIS driver naming to only include device GUID, e.g., 1268 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap 1269 specific \Device\NPF_ prefix before the GUID; the prefix is still 1270 allowed for backwards compatibility, but it is not required anymore 1271 when specifying the interface 1272 * driver_ndis: re-initialize driver interface is the adapter is removed 1273 and re-inserted [Bug 159] 1274 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on 1275 big endian hosts [Bug 146] 1276 1277 2006-04-27 - v0.5.3 1278 * fixed EAP-GTC response to include correct user identity when run as 1279 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2) 1280 * driver_ndis: Fixed encryption mode configuration for unencrypted 1281 networks (some NDIS drivers ignored this, but others, e.g., Broadcom, 1282 refused to associate with open networks) [Bug 106] 1283 * driver_ndis: use BSSID OID polling to detect when IBSS network is 1284 formed even when ndis_events code is included since some NDIS drivers 1285 do not generate media connect events in IBSS mode 1286 * config_winreg: allow global ctrl_interface parameter to be configured 1287 in Windows registry 1288 * config_winreg: added support for saving configuration data into 1289 Windows registry 1290 * added support for controlling network device operational state 1291 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see 1292 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client 1293 that can use this information) 1294 * driver_wext: added support for WE-21 change to SSID configuration 1295 * driver_wext: fixed privacy configuration for static WEP keys mode 1296 [Bug 140] 1297 * added an optional driver_ops callback for MLME-SETPROTECTION.request 1298 primitive 1299 * added support for EAP-SAKE (no EAP method number allocated yet, so 1300 this is using the same experimental type 255 as EAP-PSK) 1301 * added support for dynamically loading EAP methods (.so files) instead 1302 of requiring them to be statically linked in; this is disabled by 1303 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information 1304 on how to use this) 1305 1306 2006-03-19 - v0.5.2 1307 * do not try to use USIM APDUs when initializing PC/SC for SIM card 1308 access for a network that has not enabled EAP-AKA 1309 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in 1310 v0.5.1 due to the new support for expanded EAP types) 1311 * added support for generating EAP Expanded Nak 1312 * try to fetch scan results once before requesting new scan when 1313 starting up in ap_scan=1 mode (this can speed up initial association 1314 a lot with, e.g., madwifi-ng driver) 1315 * added support for receiving EAPOL frames from a Linux bridge 1316 interface (-bbr0 on command line) 1317 * fixed EAPOL re-authentication for sessions that used PMKSA caching 1318 * changed EAP method registration to use a dynamic list of methods 1319 instead of a static list generated at build time 1320 * fixed PMKSA cache deinitialization not to use freed memory when 1321 removing PMKSA entries 1322 * fixed a memory leak in EAP-TTLS re-authentication 1323 * reject WPA/WPA2 message 3/4 if it does not include any valid 1324 WPA/RSN IE 1325 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg 1326 if the driver does not support SIOCSIWAUTH 1327 1328 2006-01-29 - v0.5.1 1329 * driver_test: added better support for multiple APs and STAs by using 1330 a directory with sockets that include MAC address for each device in 1331 the name (driver_param=test_dir=/tmp/test) 1332 * added support for EAP expanded type (vendor specific EAP methods) 1333 * added AP_SCAN command into ctrl_iface so that ap_scan configuration 1334 option can be changed if needed 1335 * wpa_cli/wpa_gui: skip non-socket files in control directory when 1336 using UNIX domain sockets; this avoids selecting an incorrect 1337 interface (e.g., a PID file could be in this directory, even though 1338 use of this directory for something else than socket files is not 1339 recommended) 1340 * fixed TLS library deinitialization after RSN pre-authentication not 1341 to disable TLS library for normal authentication 1342 * driver_wext: Remove null-termination from SSID length if the driver 1343 used it; some Linux drivers do this and they were causing problems in 1344 wpa_supplicant not finding matching configuration block. This change 1345 would break a case where the SSID actually ends in '\0', but that is 1346 not likely to happen in real use. 1347 * fixed PMKSA cache processing not to trigger deauthentication if the 1348 current PMKSA cache entry is replaced with a valid new entry 1349 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes 1350 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or 1351 ap_scan=2) 1352 1353 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases) 1354 * added experimental STAKey handshake implementation for IEEE 802.11e 1355 direct link setup (DLS); note: this is disabled by default in both 1356 build and runtime configuration (can be enabled with CONFIG_STAKEY=y 1357 and stakey=1) 1358 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to 1359 decrypt AT_ENCR_DATA attributes correctly 1360 * fixed EAP-AKA to allow resynchronization within the same session 1361 * made code closer to ANSI C89 standard to make it easier to port to 1362 other C libraries and compilers 1363 * started moving operating system or C library specific functions into 1364 wrapper functions defined in os.h and implemented in os_*.c to make 1365 code more portable 1366 * wpa_supplicant can now be built with Microsoft Visual C++ 1367 (e.g., with the freely available Toolkit 2003 version or Visual 1368 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an 1369 example makefile for nmake 1370 * added support for using Windows registry for command line parameters 1371 (CONFIG_MAIN=main_winsvc) and configuration data 1372 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry 1373 contents; this version can be run both as a Windows service and as a 1374 normal application; 'wpasvc.exe app' to start as applicant, 1375 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service, 1376 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to 1377 unregister a service 1378 * made it possible to link ndis_events.exe functionality into 1379 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED 1380 * added better support for multiple control interface backends 1381 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported 1382 * fixed PC/SC code to use correct length for GSM AUTH command buffer 1383 and to not use pioRecvPci with SCardTransmit() calls; these were not 1384 causing visible problems with pcsc-lite, but Windows Winscard.dll 1385 refused the previously used parameters; this fixes EAP-SIM and 1386 EAP-AKA authentication using SIM/USIM card under Windows 1387 * added new event loop implementation for Windows using 1388 WaitForMultipleObject() instead of select() in order to allow waiting 1389 for non-socket objects; this can be selected with 1390 CONFIG_ELOOP=eloop_win in .config 1391 * added support for selecting l2_packet implementation in .config 1392 (CONFIG_L2_PACKET; following options are available now: linux, pcap, 1393 winpcap, freebsd, none) 1394 * added new l2_packet implementation for WinPcap 1395 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to 1396 reduce latency in EAPOL receive processing from about 100 ms to about 1397 3 ms 1398 * added support for EAP-FAST key derivation using other ciphers than 1399 RC4-128-SHA for authentication and AES128-SHA for provisioning 1400 * added support for configuring CA certificate as DER file and as a 1401 configuration blob 1402 * fixed private key configuration as configuration blob and added 1403 support for using PKCS#12 as a blob 1404 * tls_gnutls: added support for using PKCS#12 files; added support for 1405 session resumption 1406 * added support for loading trusted CA certificates from Windows 1407 certificate store: ca_cert="cert_store://<name>", where <name> is 1408 likely CA (Intermediate CA certificates) or ROOT (root certificates) 1409 * added C version of ndis_events.cpp and made it possible to build this 1410 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more 1411 easily on cross-compilation builds 1412 * added wpasvc.exe into Windows binary release; this is an alternative 1413 version of wpa_supplicant.exe with configuration backend using 1414 Windows registry and with the entry point designed to run as a 1415 Windows service 1416 * integrated ndis_events.exe functionality into wpa_supplicant.exe and 1417 wpasvc.exe and removed this additional tool from the Windows binary 1418 release since it is not needed anymore 1419 * load winscard.dll functions dynamically when building with MinGW 1420 since MinGW does not yet include winscard library 1421 1422 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases) 1423 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap 1424 and WinPcap to receive frames sent to PAE group address 1425 * disable EAP state machine when IEEE 802.1X authentication is not used 1426 in order to get rid of bogus "EAP failed" messages 1427 * fixed OpenSSL error reporting to go through all pending errors to 1428 avoid confusing reports of old errors being reported at later point 1429 during handshake 1430 * fixed configuration file updating to not write empty variables 1431 (e.g., proto or key_mgmt) that the file parser would not accept 1432 * fixed ADD_NETWORK ctrl_iface command to use the same default values 1433 for variables as empty network definitions read from config file 1434 would get 1435 * fixed EAP state machine to not discard EAP-Failure messages in many 1436 cases (e.g., during TLS handshake) 1437 * fixed a infinite loop in private key reading if the configured file 1438 cannot be parsed successfully 1439 * driver_madwifi: added support for madwifi-ng 1440 * wpa_gui: do not display password/PSK field contents 1441 * wpa_gui: added CA certificate configuration 1442 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID 1443 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if 1444 the new AP is using different WPA/RSN IE 1445 * use longer timeout for IEEE 802.11 association to avoid problems with 1446 drivers that may take more than five second to associate 1447 1448 2005-10-27 - v0.4.6 1449 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in 1450 RSN IE, but WPA IE would match with wpa_supplicant configuration 1451 * added support for named configuration blobs in order to avoid having 1452 to use file system for external files (e.g., certificates); 1453 variables can be set to "blob://<blob name>" instead of file path to 1454 use a named blob; supported fields: pac_file, client_cert, 1455 private_key 1456 * fixed RSN pre-authentication (it was broken in the clean up of WPA 1457 state machine interface in v0.4.5) 1458 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make 1459 sure the driver configures broadcast decryption correctly 1460 * added ca_path (and ca_path2) configuration variables that can be used 1461 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the 1462 system-wide trusted CA list 1463 * added support for starting wpa_supplicant without a configuration 1464 file (-C argument must be used to set ctrl_interface parameter for 1465 this case; in addition, -p argument can be used to provide 1466 driver_param; these new arguments can also be used with a 1467 configuration to override the values from the configuration) 1468 * added global control interface that can be optionally used for adding 1469 and removing network interfaces dynamically (-g command line argument 1470 for both wpa_supplicant and wpa_cli) without having to restart 1471 wpa_supplicant process 1472 * wpa_gui: 1473 - try to save configuration whenever something is modified 1474 - added WEP key configuration 1475 - added possibility to edit the current network configuration 1476 * driver_ndis: fixed driver polling not to increase frequency on each 1477 received EAPOL frame due to incorrectly cancelled timeout 1478 * added simple configuration file examples (in examples subdirectory) 1479 * fixed driver_wext.c to filter wireless events based on ifindex to 1480 avoid interfaces receiving events from other interfaces 1481 * delay sending initial EAPOL-Start couple of seconds to speed up 1482 authentication for the most common case of Authenticator starting 1483 EAP authentication immediately after association 1484 1485 2005-09-25 - v0.4.5 1486 * added a workaround for clearing keys with ndiswrapper to allow 1487 roaming from WPA enabled AP to plaintext one 1488 * added docbook documentation (doc/docbook) that can be used to 1489 generate, e.g., man pages 1490 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for 1491 PF_PACKET in order to prepare for network devices that do not use 1492 Ethernet headers (e.g., network stack with native IEEE 802.11 frames) 1493 * use receipt of EAPOL-Key frame as a lower layer success indication 1494 for EAP state machine to allow recovery from dropped EAP-Success 1495 frame 1496 * cleaned up internal EAPOL frame processing by not including link 1497 layer (Ethernet) header during WPA and EAPOL/EAP processing; this 1498 header is added only when transmitted the frame; this makes it easier 1499 to use wpa_supplicant on link layers that use different header than 1500 Ethernet 1501 * updated EAP-PSK to use draft 9 by default since this can now be 1502 tested with hostapd; removed support for draft 3, including 1503 server_nai configuration option from network blocks 1504 * driver_wired: add PAE address to the multicast address list in order 1505 to be able to receive EAPOL frames with drivers that do not include 1506 these multicast addresses by default 1507 * driver_wext: add support for WE-19 1508 * added support for multiple configuration backends (CONFIG_BACKEND 1509 option); currently, only 'file' is supported (i.e., the format used 1510 in wpa_supplicant.conf) 1511 * added support for updating configuration ('wpa_cli save_config'); 1512 this is disabled by default and can be enabled with global 1513 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli 1514 and wpa_gui to store the configuration changes in a permanent store 1515 * added GET_NETWORK ctrl_iface command 1516 (e.g., 'wpa_cli get_network 0 ssid') 1517 1518 2005-08-21 - v0.4.4 1519 * replaced OpenSSL patch for EAP-FAST support 1520 (openssl-tls-extensions.patch) with a more generic and correct 1521 patch (the new patch is not compatible with the previous one, so the 1522 OpenSSL library will need to be patched with the new patch in order 1523 to be able to build wpa_supplicant with EAP-FAST support) 1524 * added support for using Windows certificate store (through CryptoAPI) 1525 for client certificate and private key operations (EAP-TLS) 1526 (see wpa_supplicant.conf for more information on how to configure 1527 this with private_key) 1528 * ported wpa_gui to Windows 1529 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be 1530 built with the open source version of the Qt4 for Windows 1531 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used 1532 with drivers that do not support WPA 1533 * ndis_events: fixed Windows 2000 support 1534 * added support for enabling/disabling networks from the list of all 1535 configured networks ('wpa_cli enable_network <network id>' and 1536 'wpa_cli disable_network <network id>') 1537 * added support for adding and removing network from the current 1538 configuration ('wpa_cli add_network' and 'wpa_cli remove_network 1539 <network id>'); added networks are disabled by default and they can 1540 be enabled with enable_network command once the configuration is done 1541 for the new network; note: configuration file is not yet updated, so 1542 these new networks are lost when wpa_supplicant is restarted 1543 * added support for setting network configuration parameters through 1544 the control interface, for example: 1545 wpa_cli set_network 0 ssid "\"my network\"" 1546 * fixed parsing of strings that include both " and # within double 1547 quoted area (e.g., "start"#end") 1548 * added EAP workaround for PEAP session resumption: allow outer, 1549 i.e., not tunneled, EAP-Success to terminate session since; this can 1550 be disabled with eap_workaround=0 1551 (this was allowed for PEAPv1 before, but now it is also allowed for 1552 PEAPv0 since at least one RADIUS authentication server seems to be 1553 doing this for PEAPv0, too) 1554 * wpa_gui: added preliminary support for adding new networks to the 1555 wpa_supplicant configuration (double click on the scan results to 1556 open network configuration) 1557 1558 2005-06-26 - v0.4.3 1559 * removed interface for external EAPOL/EAP supplicant (e.g., 1560 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required 1561 anymore and is unlikely to be used by anyone 1562 * driver_ndis: fixed WinPcap 3.0 support 1563 * fixed build with CONFIG_DNET_PCAP=y on Linux 1564 * l2_packet: moved different implementations into separate files 1565 (l2_packet_*.c) 1566 1567 2005-06-12 - v0.4.2 1568 * driver_ipw: updated driver structures to match with ipw2200-1.0.4 1569 (note: ipw2100-1.1.0 is likely to require an update to work with 1570 this) 1571 * added support for using ap_scan=2 mode with multiple network blocks; 1572 wpa_supplicant will go through the networks one by one until the 1573 driver reports a successful association; this uses the same order for 1574 networks as scan_ssid=1 scans, i.e., the priority field is ignored 1575 and the network block order in the file is used instead 1576 * fixed a potential issue in RSN pre-authentication ending up using 1577 freed memory if pre-authentication times out 1578 * added support for matching alternative subject name extensions of the 1579 authentication server certificate; new configuration variables 1580 altsubject_match and altsubject_match2 1581 * driver_ndis: added support for IEEE 802.1X authentication with wired 1582 NDIS drivers 1583 * added support for querying private key password (EAP-TLS) through the 1584 control interface (wpa_cli/wpa_gui) if one is not included in the 1585 configuration file 1586 * driver_broadcom: fixed couple of memory leaks in scan result 1587 processing 1588 * EAP-PAX is now registered as EAP type 46 1589 * fixed EAP-PAX MAC calculation 1590 * fixed EAP-PAX CK and ICK key derivation 1591 * added support for using password with EAP-PAX (as an alternative to 1592 entering key with eappsk); SHA-1 hash of the password will be used as 1593 the key in this case 1594 * added support for arbitrary driver interface parameters through the 1595 configuration file with a new driver_param field; this adds a new 1596 driver_ops function set_param() 1597 * added possibility to override l2_packet module with driver interface 1598 API (new send_eapol handler); this can be used to implement driver 1599 specific TX/RX functions for EAPOL frames 1600 * fixed ctrl_interface_group processing for the case where gid is 1601 entered as a number, not group name 1602 * driver_test: added support for testing hostapd with wpa_supplicant 1603 by using test driver interface without any kernel drivers or network 1604 cards 1605 1606 2005-05-22 - v0.4.1 1607 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL 1608 packets to be encrypted; this was apparently broken by the changed 1609 ioctl order in v0.4.0 1610 * driver_madwifi: added preliminary support for compiling against 'BSD' 1611 branch of madwifi CVS tree 1612 * added support for EAP-MSCHAPv2 password retries within the same EAP 1613 authentication session 1614 * added support for password changes with EAP-MSCHAPv2 (used when the 1615 password has expired) 1616 * added support for reading additional certificates from PKCS#12 files 1617 and adding them to the certificate chain 1618 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys 1619 were used 1620 * fixed a possible double free in EAP-TTLS fast-reauthentication when 1621 identity or password is entered through control interface 1622 * display EAP Notification messages to user through control interface 1623 with "CTRL-EVENT-EAP-NOTIFICATION" prefix 1624 * added GUI version of wpa_cli, wpa_gui; this is not build 1625 automatically with 'make'; use 'make wpa_gui' to build (this requires 1626 Qt development tools) 1627 * added 'disconnect' command to control interface for setting 1628 wpa_supplicant in state where it will not associate before 1629 'reassociate' command has been used 1630 * added support for selecting a network from the list of all configured 1631 networks ('wpa_cli select_network <network id>'; this disabled all 1632 other networks; to re-enable, 'wpa_cli select_network any') 1633 * added support for getting scan results through control interface 1634 * added EAP workaround for PEAPv1 session resumption: allow outer, 1635 i.e., not tunneled, EAP-Success to terminate session since; this can 1636 be disabled with eap_workaround=0 1637 1638 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases) 1639 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be 1640 used to reduce the size of the wpa_supplicant considerably if 1641 debugging code is not needed 1642 * fixed EAPOL-Key validation to drop packets with invalid Key Data 1643 Length; such frames could have crashed wpa_supplicant due to buffer 1644 overflow 1645 * added support for wired authentication (IEEE 802.1X on wired 1646 Ethernet); driver interface 'wired' 1647 * obsoleted set_wpa() handler in the driver interface API (it can be 1648 replaced by moving enable/disable functionality into init()/deinit()) 1649 (calls to set_wpa() are still present for backwards compatibility, 1650 but they may be removed in the future) 1651 * driver_madwifi: fixed association in plaintext mode 1652 * modified the EAP workaround that accepts EAP-Success with incorrect 1653 Identifier to be even less strict about verification in order to 1654 interoperate with some authentication servers 1655 * added support for sending TLS alerts 1656 * added support for 'any' SSID wildcard; if ssid is not configured or 1657 is set to an empty string, any SSID will be accepted for non-WPA AP 1658 * added support for asking PIN (for SIM) from frontends (e.g., 1659 wpa_cli); if a PIN is needed, but not included in the configuration 1660 file, a control interface request is sent and EAP processing is 1661 delayed until the PIN is available 1662 * added support for using external devices (e.g., a smartcard) for 1663 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config); 1664 new wpa_supplicant.conf variables: 1665 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path 1666 - network: engine, engine_id, key_id 1667 * added experimental support for EAP-PAX 1668 * added monitor mode for wpa_cli (-a<path to a program to run>) that 1669 allows external commands (e.g., shell scripts) to be run based on 1670 wpa_supplicant events, e.g., when authentication has been completed 1671 and data connection is ready; other related wpa_cli arguments: 1672 -B (run in background), -P (write PID file); wpa_supplicant has a new 1673 command line argument (-W) that can be used to make it wait until a 1674 control interface command is received in order to avoid missing 1675 events 1676 * added support for opportunistic WPA2 PMKSA key caching (disabled by 1677 default, can be enabled with proactive_key_caching=1) 1678 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where 1679 Authenticator rejects PMKSA caching attempt and the driver is not 1680 using assoc_info events 1681 * added -P<pid file> argument for wpa_supplicant to write the current 1682 process id into a file 1683 1684 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases) 1685 * added new phase1 option parameter, include_tls_length=1, to force 1686 wpa_supplicant to add TLS Message Length field to all TLS messages 1687 even if the packet is not fragmented; this may be needed with some 1688 authentication servers 1689 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when 1690 using drivers that take care of AP selection (e.g., when using 1691 ap_scan=2) 1692 * fixed reprocessing of pending request after ctrl_iface requests for 1693 identity/password/otp 1694 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of 1695 EAP-PEAP and EAP-TTLS 1696 * all drivers using driver_wext: set interface up and select Managed 1697 mode when starting wpa_supplicant; set interface down when exiting 1698 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both 1699 ipw2100 and ipw2200; please note that this also changed the 1700 configuration variable in .config to CONFIG_DRIVER_IPW 1701 1702 2005-01-24 - v0.3.6 1703 * fixed a busy loop introduced in v0.3.5 for scan result processing 1704 when no matching AP is found 1705 1706 2005-01-23 - v0.3.5 1707 * added a workaround for an interoperability issue with a Cisco AP 1708 when using WPA2-PSK 1709 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as 1710 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow 1711 retransmission of dropped frames) 1712 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version 1713 (e.g., segfault when processing EAPOL-Key frames) 1714 * fixed EAP workaround and fast reauthentication configuration for 1715 RSN pre-authentication; previously these were disabled and 1716 pre-authentication would fail if the used authentication server 1717 requires EAP workarounds 1718 * added support for blacklisting APs that fail or timeout 1719 authentication in ap_scan=1 mode so that all APs are tried in cases 1720 where the ones with strongest signal level are failing authentication 1721 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS 1722 authentication attempt 1723 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded 1724 in the previous authentication (previously, only Phase 1 success was 1725 verified) 1726 1727 2005-01-09 - v0.3.4 1728 * added preliminary support for IBSS (ad-hoc) mode configuration 1729 (mode=1 in network block); this included a new key_mgmt mode 1730 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no 1731 key management; see wpa_supplicant.conf for more details and an 1732 example on how to configure this (note: this is currently implemented 1733 only for driver_hostapd.c, but the changes should be trivial to add 1734 in associate() handler for other drivers, too (assuming the driver 1735 supports WPA-None) 1736 * added preliminary port for native Windows (i.e., no cygwin) using 1737 mingw 1738 1739 2005-01-02 - v0.3.3 1740 * added optional support for GNU Readline and History Libraries for 1741 wpa_cli (CONFIG_READLINE) 1742 * cleaned up EAP state machine <-> method interface and number of 1743 small problems with error case processing not terminating on 1744 EAP-Failure but waiting for timeout 1745 * added couple of workarounds for interoperability issues with a 1746 Cisco AP when using WPA2 1747 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt); 1748 Note: This requires a patch for openssl to add support for TLS 1749 extensions and number of workarounds for operations without 1750 certificates. Proof of concept type of experimental patch is 1751 included in openssl-tls-extensions.patch. 1752 1753 2004-12-19 - v0.3.2 1754 * fixed private key loading for cases where passphrase is not set 1755 * fixed Windows/cygwin L2 packet handler freeing; previous version 1756 could cause a segfault when RSN pre-authentication was completed 1757 * added support for PMKSA caching with drivers that generate RSN IEs 1758 (e.g., NDIS); currently, this is only implemented in driver_ndis.c, 1759 but similar code can be easily added to driver_ndiswrapper.c once 1760 ndiswrapper gets full support for RSN PMKSA caching 1761 * improved recovery from PMKID mismatches by requesting full EAP 1762 authentication in case of failed PMKSA caching attempt 1763 * driver_ndis: added support for NDIS NdisMIncidateStatus() events 1764 (this requires that ndis_events is ran while wpa_supplicant is 1765 running) 1766 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys 1767 * added support for driver interfaces to replace the interface name 1768 based on driver/OS specific mapping, e.g., in case of driver_ndis, 1769 this allows the beginning of the adapter description to be used as 1770 the interface name 1771 * added support for CR+LF (Windows-style) line ends in configuration 1772 file 1773 * driver_ndis: enable radio before starting scanning, disable radio 1774 when exiting 1775 * modified association event handler to set portEnabled = FALSE before 1776 clearing port Valid in order to reset EAP state machine and avoid 1777 problems with new authentication getting ignored because of state 1778 machines ending up in AUTHENTICATED/SUCCESS state based on old 1779 information 1780 * added support for driver events to add PMKID candidates in order to 1781 allow drivers to give priority to most likely roaming candidates 1782 * driver_hostap: moved PrivacyInvoked configuration to associate() 1783 function so that this will not be set for plaintext connections 1784 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver 1785 interface can distinguish plaintext and IEEE 802.1X (no WPA) 1786 authentication 1787 * fixed static WEP key configuration to use broadcast/default type for 1788 all keys (previously, the default TX key was configured as pairwise/ 1789 unicast key) 1790 * driver_ndis: added legacy WPA capability detection for non-WPA2 1791 drivers 1792 * added support for setting static WEP keys for IEEE 802.1X without 1793 dynamic WEP keying (eapol_flags=0) 1794 1795 2004-12-12 - v0.3.1 1796 * added support for reading PKCS#12 (PFX) files (as a replacement for 1797 PEM/DER) to get certificate and private key (CONFIG_PKCS12) 1798 * fixed compilation with CONFIG_PCSC=y 1799 * added new ap_scan mode, ap_scan=2, for drivers that take care of 1800 association, but need to be configured with security policy and SSID, 1801 e.g., ndiswrapper and NDIS driver; this mode should allow such 1802 drivers to work with hidden SSIDs and optimized roaming; when 1803 ap_scan=2 is used, only the first network block in the configuration 1804 file is used and this configuration should have explicit security 1805 policy (i.e., only one option in the lists) for key_mgmt, pairwise, 1806 group, proto variables 1807 * added experimental port of wpa_supplicant for Windows 1808 - driver_ndis.c driver interface (NDIS OIDs) 1809 - currently, this requires cygwin and WinPcap 1810 - small utility, win_if_list, can be used to get interface name 1811 * control interface can now be removed at build time; add 1812 CONFIG_CTRL_IFACE=y to .config to maintain old functionality 1813 * optional Xsupplicant interface can now be removed at build time; 1814 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back) 1815 * added auth_alg to driver interface associate() parameters to make it 1816 easier for drivers to configure authentication algorithm as part of 1817 the association 1818 1819 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases) 1820 * driver_broadcom: added new driver interface for Broadcom wl.o driver 1821 (a generic driver for Broadcom IEEE 802.11a/g cards) 1822 * wpa_cli: fixed parsing of -p <path> command line argument 1823 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS 1824 ACK, not tunneled EAP-Success (of which only the first byte was 1825 actually send due to a bug in previous code); this seems to 1826 interoperate with most RADIUS servers that implements PEAPv1 1827 * PEAPv1: added support for terminating PEAP authentication on tunneled 1828 EAP-Success message; this can be configured by adding 1829 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf 1830 (some RADIUS servers require this whereas others require a tunneled 1831 reply 1832 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to 1833 the old label for key derivation; previously, the default was 1, 1834 but it looks like most existing PEAPv1 implementations use the old 1835 label which is thus more suitable default option 1836 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt) 1837 * fixed parsing of wep_tx_keyidx 1838 * added support for configuring list of allowed Phase 2 EAP types 1839 (for both EAP-PEAP and EAP-TTLS) instead of only one type 1840 * added support for configuring IEEE 802.11 authentication algorithm 1841 (auth_alg; mainly for using Shared Key authentication with static 1842 WEP keys) 1843 * added support for EAP-AKA (with UMTS SIM) 1844 * fixed couple of errors in PCSC handling that could have caused 1845 random-looking errors for EAP-SIM 1846 * added support for EAP-SIM pseudonyms and fast re-authentication 1847 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS 1848 session resumption) 1849 * added support for EAP-SIM with two challanges 1850 (phase1="sim_min_num_chal=3" can be used to require three challenges) 1851 * added support for configuring DH/DSA parameters for an ephemeral DH 1852 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters 1853 dh_file and dh_file2 (phase 2); this adds support for using DSA keys 1854 and optional DH key exchange to achieve forward secracy with RSA keys 1855 * added support for matching subject of the authentication server 1856 certificate with a substring when using EAP-TLS/PEAP/TTLS; new 1857 configuration variables subject_match and subject_match2 1858 * changed SSID configuration in driver_wext.c (used by many driver 1859 interfaces) to use ssid_len+1 as the length for SSID since some Linux 1860 drivers expect this 1861 * fixed couple of unaligned reads in scan result parsing to fix WPA 1862 connection on some platforms (e.g., ARM) 1863 * added driver interface for Intel ipw2100 driver 1864 * added support for LEAP with WPA 1865 * added support for larger scan results report (old limit was 4 kB of 1866 data, i.e., about 35 or so APs) when using Linux wireless extensions 1867 v17 or newer 1868 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start 1869 only if there is a PMKSA cache entry for the current AP 1870 * fixed error handling for case where reading of scan results fails: 1871 must schedule a new scan or wpa_supplicant will remain waiting 1872 forever 1873 * changed debug output to remove shared password/key material by 1874 default; all key information can be included with -K command line 1875 argument to match the previous behavior 1876 * added support for timestamping debug log messages (disabled by 1877 default, can be enabled with -t command line argument) 1878 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104 1879 if keys are not configured to be used; this fixes IEEE 802.1X mode 1880 with drivers that use this information to configure whether Privacy 1881 bit can be in Beacon frames (e.g., ndiswrapper) 1882 * avoid clearing driver keys if no keys have been configured since last 1883 key clear request; this seems to improve reliability of group key 1884 handshake for ndiswrapper & NDIS driver which seems to be suffering 1885 of some kind of timing issue when the keys are cleared again after 1886 association 1887 * changed driver interface API: 1888 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which 1889 version is being used (now, this is set to 2; previously, it was 1890 not defined) 1891 - pass pointer to private data structure to all calls 1892 - the new API is not backwards compatible; all in-tree driver 1893 interfaces has been converted to the new API 1894 * added support for controlling multiple interfaces (radios) per 1895 wpa_supplicant process; each interface needs to be listed on the 1896 command line (-c, -i, -D arguments) with -N as a separator 1897 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi) 1898 * added a workaround for EAP servers that incorrectly use same Id for 1899 sequential EAP packets 1900 * changed libpcap/libdnet configuration to use .config variable, 1901 CONFIG_DNET_PCAP, instead of requiring Makefile modification 1902 * improved downgrade attack detection in IE verification of msg 3/4: 1903 verify both WPA and RSN IEs, if present, not only the selected one; 1904 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or 1905 Probe Response frame, and RSN is enabled in wpa_supplicant 1906 configuration 1907 * fixed WPA msg 3/4 processing to allow Key Data field contain other 1908 IEs than just one WPA IE 1909 * added support for FreeBSD and driver interface for the BSD net80211 1910 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the 1911 required kernel mods have not yet been committed 1912 * made EAP workarounds configurable; enabled by default, can be 1913 disabled with network block option eap_workaround=0 1914 1915 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases) 1916 * resolved couple of interoperability issues with EAP-PEAPv1 and 1917 Phase 2 (inner EAP) fragment reassembly 1918 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the 1919 AP is using non-zero key index for the unicast key and key index zero 1920 for the broadcast key 1921 * driver_hostap: fixed IEEE 802.1X WEP key updates and 1922 re-authentication by allowing unencrypted EAPOL frames when not using 1923 WPA 1924 * added a new driver interface, 'wext', which uses only standard, 1925 driver independent functionality in Linux wireless extensions; 1926 currently, this can be used only for non-WPA IEEE 802.1X mode, but 1927 eventually, this is to be extended to support full WPA/WPA2 once 1928 Linux wireless extensions get support for this 1929 * added support for mode in which the driver is responsible for AP 1930 scanning and selection; this is disabled by default and can be 1931 enabled with global ap_scan=0 variable in wpa_supplicant.conf; 1932 this mode can be used, e.g., with generic 'wext' driver interface to 1933 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver 1934 supporting wireless extensions. 1935 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g., 1936 operation with an AP that does not include SSID in the Beacon frames) 1937 * added support for new EAP authentication methods: 1938 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP 1939 * added support for asking one-time-passwords from frontends (e.g., 1940 wpa_cli); this 'otp' command works otherwise like 'password' command, 1941 but the password is used only once and the frontend will be asked for 1942 a new password whenever a request from authenticator requires a 1943 password; this can be used with both EAP-OTP and EAP-GTC 1944 * changed wpa_cli to automatically re-establish connection so that it 1945 does not need to be re-started when wpa_supplicant is terminated and 1946 started again 1947 * improved user data (identity/password/otp) requests through 1948 frontends: process pending EAPOL packets after getting new 1949 information so that full authentication does not need to be 1950 restarted; in addition, send pending requests again whenever a new 1951 frontend is attached 1952 * changed control frontends to use a new directory for socket files to 1953 make it easier for wpa_cli to automatically select between interfaces 1954 and to provide access control for the control interface; 1955 wpa_supplicant.conf: ctrl_interface is now a path 1956 (/var/run/wpa_supplicant is the recommended path) and 1957 ctrl_interface_group can be used to select which group gets access to 1958 the control interface; 1959 wpa_cli: by default, try to connect to the first interface available 1960 in /var/run/wpa_supplicant; this path can be overriden with -p option 1961 and an interface can be selected with -i option (i.e., in most common 1962 cases, wpa_cli does not need to get any arguments) 1963 * added support for LEAP 1964 * added driver interface for Linux ndiswrapper 1965 * added priority option for network blocks in the configuration file; 1966 this allows networks to be grouped based on priority (the scan 1967 results are searched for matches with network blocks in this order) 1968 1969 2004-06-20 - v0.2.3 1970 * sort scan results to improve AP selection 1971 * fixed control interface socket removal for some error cases 1972 * improved scan requesting and authentication timeout 1973 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and 1974 TLS processing 1975 * PEAP version can now be forced with phase1="peapver=<ver>" 1976 (mostly for testing; by default, the highest version supported by 1977 both the Supplicant and Authentication Server is selected 1978 automatically) 1979 * added support for madwifi driver (Atheros ar521x) 1980 * added a workaround for cases where AP sets Install Tx/Rx bit for 1981 WPA Group Key messages when pairwise keys are used (without this, 1982 the Group Key would be used for Tx and the AP would drop frames 1983 from the station) 1984 * added GSM SIM/USIM interface for GSM authentication algorithm for 1985 EAP-SIM; this requires pcsc-lite 1986 * added support for ATMEL AT76C5XXx driver 1987 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator 1988 does not include key data in the EAPOL-Key frame (i.e., part of 1989 EAP keying material is used as data encryption key) 1990 * added support for using plaintext and static WEP networks 1991 (key_mgmt=NONE) 1992 1993 2004-05-31 - v0.2.2 1994 * added support for new EAP authentication methods: 1995 EAP-TTLS/EAP-MD5-Challenge 1996 EAP-TTLS/EAP-GTC 1997 EAP-TTLS/EAP-MSCHAPv2 1998 EAP-TTLS/EAP-TLS 1999 EAP-TTLS/MSCHAPv2 2000 EAP-TTLS/MSCHAP 2001 EAP-TTLS/PAP 2002 EAP-TTLS/CHAP 2003 EAP-PEAP/TLS 2004 EAP-PEAP/GTC 2005 EAP-PEAP/MD5-Challenge 2006 EAP-GTC 2007 EAP-SIM (not yet complete; needs GSM/SIM authentication interface) 2008 * added support for anonymous identity (to be used when identity is 2009 sent in plaintext; real identity will be used within TLS protected 2010 tunnel (e.g., with EAP-TTLS) 2011 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli 2012 * added support for requesting identity and password information using 2013 control interface; in other words, the password for EAP-PEAP or 2014 EAP-TTLS does not need to be included in the configuration file since 2015 a frontand (e.g., wpa_cli) can ask it from the user 2016 * improved RSN pre-authentication to use a candidate list and process 2017 all candidates from each scan; not only one per scan 2018 * fixed RSN IE and WPA IE capabilities field parsing 2019 * ignore Tx bit in GTK IE when Pairwise keys are used 2020 * avoid making new scan requests during IEEE 802.1X negotiation 2021 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant 2022 with TLS support (this replaces the included implementation with 2023 library code to save about 8 kB since the library code is needed 2024 anyway for TLS) 2025 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support 2026 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config) 2027 2028 2004-05-06 - v0.2.1 2029 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1) 2030 Supplicant 2031 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1] 2032 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf] 2033 - EAP-MD5 (cannot be used with WPA-RADIUS) 2034 [draft-ietf-eap-rfc2284bis-09.txt] 2035 - EAP-TLS [RFC 2716] 2036 - EAP-MSCHAPv2 (currently used only with EAP-PEAP) 2037 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt] 2038 [draft-kamath-pppext-eap-mschapv2-00.txt] 2039 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by 2040 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey) 2041 - new configuration file options: eap, identity, password, ca_cert, 2042 client_cert, privatekey, private_key_passwd 2043 - Xsupplicant is not required anymore, but it can be used by 2044 disabling the internal IEEE 802.1X Supplicant with -e command line 2045 option 2046 - this code is not included in the default build; Makefile need to 2047 be edited for this (uncomment lines for selected functionality) 2048 - EAP-TLS and EAP-PEAP require openssl libraries 2049 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..) 2050 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys 2051 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X 2052 EAPOL-Key frames instead of WPA key handshakes) 2053 * added support for IEEE 802.11i/RSN (WPA2) 2054 - improved PTK Key Handshake 2055 - PMKSA caching, pre-authentication 2056 * fixed wpa_supplicant to ignore possible extra data after WPA 2057 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using 2058 TPTK' error from message 3 of 4-Way Handshake in case the AP 2059 includes extra data after the EAPOL-Key) 2060 * added interface for external programs (frontends) to control 2061 wpa_supplicant 2062 - CLI example (wpa_cli) with interactive mode and command line 2063 mode 2064 - replaced SIGUSR1 status/statistics with the new control interface 2065 * made some feature compile time configurable 2066 - .config file for make 2067 - driver interfaces (hostap, hermes, ..) 2068 - EAPOL/EAP functions 2069 2070 2004-02-15 - v0.2.0 2071 * Initial version of wpa_supplicant 2072
