Only 532 available with drivers that provide TX status events for Deauth/ 533 Disassoc frames (nl80211). 534 * Drop oldest unknown BSS table entries first. This makes it less 535 likely to hit connection issues in environments with huge number 536 of visible APs. 537 * Add systemd support. 538 * Add support for setting the syslog facility from the config file 539 at build time. 540 * atheros: Add support for IEEE 802.11w configuration. 541 * AP mode: Allow enable HT20 if driver supports it, by setting the 542 config parameter ieee80211n. 543 * Allow AP mode to disconnect STAs based on low ACK condition (when 544 the data connection is not working properly, e.g., due to the STA 545 going outside the range of the AP). Disabled by default, enable by 546 config option disassoc_low_ack. 547 * nl80211: 548 - Support GTK rekey offload. 549 - Support PMKSA candidate events. This adds support for RSN 550 pre-authentication with nl80211 interface and drivers that handle 551 roaming internally. 552 * dbus: 553 - Add a DBus signal for EAP SM requests, emitted on the Interface 554 object. 555 - Export max scan ssids supported by the driver as MaxScanSSID. 556 - Add signal Certification for information about server certification. 557 - Add BSSExpireAge and BSSExpireCount interface properties and 558 support set/get, which allows for setting BSS cache expiration age 559 and expiration scan count. 560 - Add ConfigFile to AddInterface properties. 561 - Add Interface.Country property and support to get/set the value. 562 - Add DBus property CurrentAuthMode. 563 - P2P DBus API added. 564 - Emit property changed events (for property BSSs) when adding/ 565 removing BSSs. 566 - Treat '' in SSIDs of Interface.Scan as a request for broadcast 567 scan, instead of ignoring it. 568 - Add DBus getter/setter for FastReauth. 569 - Raise PropertiesChanged on org.freedesktop.DBus.Properties. 570 * wpa_cli: 571 - Send AP-STA-DISCONNECTED event when an AP disconnects a station 572 due to inactivity. 573 - Make second argument to set command optional. This can be used to 574 indicate a zero length value. 575 - Add signal_poll command. 576 - Add bss_expire_age and bss_expire_count commands to set/get BSS 577 cache expiration age and expiration scan count. 578 - Add ability to set scan interval (the time in seconds wpa_s waits 579 before requesting a new scan after failing to find a suitable 580 network in scan results) using scan_interval command. 581 - Add event CTRL-EVENT-ASSOC-REJECT for association rejected. 582 - Add command get version, that returns wpa_supplicant version string. 583 - Add command sta_autoconnect for disabling automatic reconnection 584 on receiving disconnection event. 585 - Setting bssid parameter to an empty string "" or any can now be 586 used to clear the bssid_set flag in a network block, i.e., to remove 587 bssid filtering. 588 - Add tdls_testing command to add a special testing feature for 589 changing TDLS behavior. Build param CONFIG_TDLS_TESTING must be 590 enabled as well. 591 - For interworking, add wpa_cli commands interworking_select, 592 interworking_connect, anqp_get, fetch_anqp, and stop_fetch_anqp. 593 - Many P2P commands were added. See README-P2P. 594 - Many WPS/WPS ER commands - see WPS/WPS ER sections for details. 595 - Allow set command to change global config parameters. 596 - Add log_level command, which can be used to display the current 597 debugging level and to change the log level during run time. 598 - Add note command, which can be used to insert notes to the debug 599 log. 600 - Add internal line edit implementation. CONFIG_WPA_CLI_EDIT=y 601 can now be used to build wpa_cli with internal implementation of 602 line editing and history support. This can be used as a replacement 603 for CONFIG_READLINE=y. 604 * AP mode: Add max_num_sta config option, which can be used to limit 605 the number of stations allowed to connect to the AP. 606 * Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad 607 config file. 608 * wext: Increase scan timeout from 5 to 10 seconds. 609 * Add blacklist command, allowing an external program to 610 manage the BSS blacklist and display its current contents. 611 * WPS: 612 - Add wpa_cli wps_pin get command for generating random PINs. This can 613 be used in a UI to generate a PIN without starting WPS (or P2P) 614 operation. 615 - Set RF bands based on driver capabilities, instead of hardcoding 616 them. 617 - Add mechanism for indicating non-standard WPS errors. 618 - Add CONFIG_WPS_REG_DISABLE_OPEN=y option to disable open networks 619 by default. 620 - Add wps_ap_pin cli command for wpa_supplicant AP mode. 621 - Add wps_check_pin cli command for processing PIN from user input. 622 UIs can use this command to process a PIN entered by a user and to 623 validate the checksum digit (if present). 624 - Cancel WPS operation on PBC session overlap detection. 625 - New wps_cancel command in wpa_cli will cancel a pending WPS 626 operation. 627 - wpa_cli action: Add WPS_EVENT_SUCCESS and WPS_EVENT_FAIL handlers. 628 - Trigger WPS config update on Manufacturer, Model Name, Model 629 Number, and Serial Number changes. 630 - Fragment size is now configurable for EAP-WSC peer. Use 631 wpa_cli set wps_fragment_size <val>. 632 - Disable AP PIN after 10 consecutive failures. Slow down attacks on 633 failures up to 10. 634 - Allow AP to start in Enrollee mode without AP PIN for probing, to 635 be compatible with Windows 7. 636 - Add Config Error into WPS-FAIL events to provide more info to the 637 user on how to resolve the issue. 638 - Label and Display config methods are not allowed to be enabled 639 at the same time, since it is unclear which PIN to use if both 640 methods are advertised. 641 - When controlling multiple interfaces: 642 - apply WPS commands to all interfaces configured to use WPS 643 - apply WPS config changes to all interfaces that use WPS 644 - when an attack is detected on any interface, disable AP PIN on 645 all interfaces 646 * WPS ER: 647 - Add special AP Setup Locked mode to allow read only ER. 648 ap_setup_locked=2 can now be used to enable a special mode where 649 WPS ER can learn the current AP settings, but cannot change them. 650 - Show SetSelectedRegistrar events as ctrl_iface events 651 - Add wps_er_set_config to enroll a network based on a local 652 network configuration block instead of having to (re-)learn the 653 current AP settings with wps_er_learn. 654 - Allow AP filtering based on IP address, add ctrl_iface event for 655 learned AP settings, add wps_er_config command to configure an AP. 656 * WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2) 657 - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool 658 for testing protocol extensibility. 659 - Add build option CONFIG_WPS_STRICT to allow disabling of WPS 660 workarounds. 661 - Add support for AuthorizedMACs attribute. 662 * TDLS: 663 - Propogate TDLS related nl80211 capability flags from kernel and 664 add them as driver capability flags. If the driver doesn't support 665 capabilities, assume TDLS is supported internally. When TDLS is 666 explicitly not supported, disable all user facing TDLS operations. 667 - Allow TDLS to be disabled at runtime (mostly for testing). 668 Use set tdls_disabled. 669 - Honor AP TDLS settings that prohibit/allow TDLS. 670 - Add a special testing feature for changing TDLS behavior. Use 671 CONFIG_TDLS_TESTING build param to enable. Configure at runtime 672 with tdls_testing cli command. 673 - Add support for TDLS 802.11z. 674 * wlantest: Add a tool wlantest for IEEE802.11 protocol testing. 675 wlantest can be used to capture frames from a monitor interface 676 for realtime capturing or from pcap files for offline analysis. 677 * Interworking: Support added for 802.11u. Enable in .config with 678 CONFIG_INTERWORKING. See wpa_supplicant.conf for config parameters 679 for interworking. wpa_cli commands added to support this are 680 interworking_select, interworking_connect, anqp_get, fetch_anqp, 681 and stop_fetch_anqp. 682 * Android: Add build and runtime support for Android wpa_supplicant. 683 * bgscan learn: Add new bgscan that learns BSS information based on 684 previous scans, and uses that information to dynamically generate 685 the list of channels for background scans. 686 * Add a new debug message level for excessive information. Use 687 -ddd to enable. 688 * TLS: Add support for tls_disable_time_checks=1 in client mode. 689 * Internal TLS: 690 - Add support for TLS v1.1 (RFC 4346). Enable with build parameter 691 CONFIG_TLSV11. 692 - Add domainComponent parser for X.509 names. 693 * Linux: Add RFKill support by adding an interface state "disabled". 694 * Reorder some IEs to get closer to IEEE 802.11 standard. Move 695 WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames. 696 Move HT IEs to be later in (Re)Assoc Resp. 697 * Solaris: Add support for wired 802.1X client. 698 * Wi-Fi Direct support. See README-P2P for more information. 699 * Many bugfixes. 700 701 2010-04-18 - v0.7.2 702 * nl80211: fixed number of issues with roaming 703 * avoid unnecessary roaming if multiple APs with similar signal 704 strength are present in scan results 705 * add TLS client events and server probing to ease design of 706 automatic detection of EAP parameters 707 * add option for server certificate matching (SHA256 hash of the 708 certificate) instead of trusted CA certificate configuration 709 * bsd: Cleaned up driver wrapper and added various low-level 710 configuration options 711 * wpa_gui-qt4: do not show too frequent WPS AP available events as 712 tray messages 713 * TNC: fixed issues with fragmentation 714 * EAP-TNC: add Flags field into fragment acknowledgement (needed to 715 interoperate with other implementations; may potentially breaks 716 compatibility with older wpa_supplicant/hostapd versions) 717 * wpa_cli: added option for using a separate process to receive event 718 messages to reduce latency in showing these 719 (CFLAGS += -DCONFIG_WPA_CLI_FORK=y in .config to enable this) 720 * maximum BSS table size can now be configured (bss_max_count) 721 * BSSes to be included in the BSS table can be filtered based on 722 configured SSIDs to save memory (filter_ssids) 723 * fix number of issues with IEEE 802.11r/FT; this version is not 724 backwards compatible with old versions 725 * nl80211: add support for IEEE 802.11r/FT protocol (both over-the-air 726 and over-the-DS) 727 * add freq_list network configuration parameter to allow the AP 728 selection to filter out entries based on the operating channel 729 * add signal strength change events for bgscan; this allows more 730 dynamic changes to background scanning interval based on changes in 731 the signal strength with the current AP; this improves roaming within 732 ESS quite a bit, e.g., with bgscan="simple:30:-45:300" in the network 733 configuration block to request background scans less frequently when 734 signal strength remains good and to automatically trigger background 735 scans whenever signal strength drops noticeably 736 (this is currently only available with nl80211) 737 * add BSSID and reason code (if available) to disconnect event messages 738 * wpa_gui-qt4: more complete support for translating the GUI with 739 linguist and add German translation 740 * fix DH padding with internal crypto code (mainly, for WPS) 741 * do not trigger initial scan automatically anymore if there are no 742 enabled networks 743 744 2010-01-16 - v0.7.1 745 * cleaned up driver wrapper API (struct wpa_driver_ops); the new API 746 is not fully backwards compatible, so out-of-tree driver wrappers 747 will need modifications 748 * cleaned up various module interfaces 749 * merge hostapd and wpa_supplicant developers' documentation into a 750 single document 751 * nl80211: use explicit deauthentication to clear cfg80211 state to 752 avoid issues when roaming between APs 753 * dbus: major design changes in the new D-Bus API 754 (fi.w1.wpa_supplicant1) 755 * nl80211: added support for IBSS networks 756 * added internal debugging mechanism with backtrace support and memory 757 allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y) 758 * added WPS ER unsubscription command to more cleanly unregister from 759 receiving UPnP events when ER is terminated 760 * cleaned up AP mode operations to avoid need for virtual driver_ops 761 wrapper 762 * added BSS table to maintain more complete scan result information 763 over multiple scans (that may include only partial results) 764 * wpa_gui-qt4: update Peers dialog information more dynamically while 765 the dialog is kept open 766 * fixed PKCS#12 use with OpenSSL 1.0.0 767 * driver_wext: Added cfg80211-specific optimization to avoid some 768 unnecessary scans and to speed up association 769 770 2009-11-21 - v0.7.0 771 * increased wpa_cli ping interval to 5 seconds and made this 772 configurable with a new command line options (-G<seconds>) 773 * fixed scan buffer processing with WEXT to handle up to 65535 774 byte result buffer (previously, limited to 32768 bytes) 775 * allow multiple driver wrappers to be specified on command line 776 (e.g., -Dnl80211,wext); the first one that is able to initialize the 777 interface will be used 778 * added support for multiple SSIDs per scan request to optimize 779 scan_ssid=1 operations in ap_scan=1 mode (i.e., search for hidden 780 SSIDs); this requires driver support and can currently be used only 781 with nl80211 782 * added support for WPS USBA out-of-band mechanism with USB Flash 783 Drives (UFD) (CONFIG_WPS_UFD=y) 784 * driver_ndis: add PAE group address to the multicast address list to 785 fix wired IEEE 802.1X authentication 786 * fixed IEEE 802.11r key derivation function to match with the standard 787 (note: this breaks interoperability with previous version) [Bug 303] 788 * added better support for drivers that allow separate authentication 789 and association commands (e.g., mac80211-based Linux drivers with 790 nl80211; SME in wpa_supplicant); this allows over-the-air FT protocol 791 to be used (IEEE 802.11r) 792 * fixed SHA-256 based key derivation function to match with the 793 standard when using CCMP (for IEEE 802.11r and IEEE 802.11w) 794 (note: this breaks interoperability with previous version) [Bug 307] 795 * use shared driver wrapper files with hostapd 796 * added AP mode functionality (CONFIG_AP=y) with mode=2 in the network 797 block; this can be used for open and WPA2-Personal networks 798 (optionally, with WPS); this links in parts of hostapd functionality 799 into wpa_supplicant 800 * wpa_gui-qt4: added new Peers dialog to show information about peers 801 (other devices, including APs and stations, etc. in the neighborhood) 802 * added support for WPS External Registrar functionality (configure APs 803 and enroll new devices); can be used with wpa_gui-qt4 Peers dialog 804 and wpa_cli commands wps_er_start, wps_er_stop, wps_er_pin, 805 wps_er_pbc, wps_er_learn 806 (this can also be used with a new 'none' driver wrapper if no 807 wireless device or IEEE 802.1X on wired is needed) 808 * driver_nl80211: multiple updates to provide support for new Linux 809 nl80211/mac80211 functionality 810 * updated management frame protection to use IEEE Std 802.11w-2009 811 * fixed number of small WPS issues and added workarounds to 812 interoperate with common deployed broken implementations 813 * added support for NFC out-of-band mechanism with WPS 814 * driver_ndis: fixed wired IEEE 802.1X authentication with PAE group 815 address frames 816 * added preliminary support for IEEE 802.11r RIC processing 817 * added support for specifying subset of enabled frequencies to scan 818 (scan_freq option in the network configuration block); this can speed 819 up scanning process considerably if it is known that only a small 820 subset of channels is actually used in the network (this is currently 821 supported only with -Dnl80211) 822 * added a workaround for race condition between receiving the 823 association event and the following EAPOL-Key 824 * added background scan and roaming infrastructure to allow 825 network-specific optimizations to be used to improve roaming within 826 an ESS (same SSID) 827 * added new DBus interface (fi.w1.wpa_supplicant1) 828 829 2009-01-06 - v0.6.7 830 * added support for Wi-Fi Protected Setup (WPS) 831 (wpa_supplicant can now be configured to act as a WPS Enrollee to 832 enroll credentials for a network using PIN and PBC methods; in 833 addition, wpa_supplicant can act as a wireless WPS Registrar to 834 configure an AP); WPS support can be enabled by adding CONFIG_WPS=y 835 into .config and setting the runtime configuration variables in 836 wpa_supplicant.conf (see WPS section in the example configuration 837 file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to 838 manage WPS negotiation; see README-WPS for more details 839 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf) 840 * added support for using driver_test over UDP socket 841 * fixed PEAPv0 Cryptobinding interoperability issue with Windows Server 842 2008 NPS; optional cryptobinding is now enabled (again) by default 843 * fixed PSK editing in wpa_gui 844 * changed EAP-GPSK to use the IANA assigned EAP method type 51 845 * added a Windows installer that includes WinPcap and all the needed 846 DLLs; in addition, it set up the registry automatically so that user 847 will only need start wpa_gui to get prompted to start the wpasvc 848 servide and add a new interface if needed through wpa_gui dialog 849 * updated management frame protection to use IEEE 802.11w/D7.0 850 851 2008-11-23 - v0.6.6 852 * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA 853 (can be used to simulate test SIM/USIM card with a known private key; 854 enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config 855 and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration) 856 * added a new network configuration option, wpa_ptk_rekey, that can be 857 used to enforce frequent PTK rekeying, e.g., to mitigate some attacks 858 against TKIP deficiencies 859 * added an optional mitigation mechanism for certain attacks against 860 TKIP by delaying Michael MIC error reports by a random amount of time 861 between 0 and 60 seconds; this can be enabled with a build option 862 CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config 863 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits, 864 not bytes 865 * updated OpenSSL code for EAP-FAST to use an updated version of the 866 session ticket overriding API that was included into the upstream 867 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is 868 needed with that version anymore) 869 * updated userspace MLME instructions to match with the current Linux 870 mac80211 implementation; please also note that this can only be used 871 with driver_nl80211.c (the old code from driver_wext.c was removed) 872 * added support (Linux only) for RoboSwitch chipsets (often found in 873 consumer grade routers); driver interface 'roboswitch' 874 * fixed canceling of PMKSA caching when using drivers that generate 875 RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know 876 about 877 878 2008-11-01 - v0.6.5 879 * added support for SHA-256 as X.509 certificate digest when using the 880 internal X.509/TLSv1 implementation 881 * updated management frame protection to use IEEE 802.11w/D6.0 882 * added support for using SHA256-based stronger key derivation for WPA2 883 (IEEE 802.11w) 884 * fixed FT (IEEE 802.11r) authentication after a failed association to 885 use correct FTIE 886 * added support for configuring Phase 2 (inner/tunneled) authentication 887 method with wpa_gui-qt4 888 889 2008-08-10 - v0.6.4 890 * added support for EAP Sequences in EAP-FAST Phase 2 891 * added support for using TNC with EAP-FAST 892 * added driver_ps3 for the PS3 Linux wireless driver 893 * added support for optional cryptobinding with PEAPv0 894 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to 895 allow fallback to full handshake if server rejects PAC-Opaque 896 * added fragmentation support for EAP-TNC 897 * added support for parsing PKCS #8 formatted private keys into the 898 internal TLS implementation (both PKCS #1 RSA key and PKCS #8 899 encapsulated RSA key can now be used) 900 * added option of using faster, but larger, routines in the internal 901 LibTomMath (for internal TLS implementation) to speed up DH and RSA 902 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y) 903 * fixed race condition between disassociation event and group key 904 handshake to avoid getting stuck in incorrect state [Bug 261] 905 * fixed opportunistic key caching (proactive_key_caching) 906 907 2008-02-22 - v0.6.3 908 * removed 'nai' and 'eappsk' network configuration variables that were 909 previously used for configuring user identity and key for EAP-PSK, 910 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the 911 replacement for 'nai' (if old configuration used a separate 912 'identity' value, that would now be configured as 913 'anonymous_identity'). 'password' field is now used as the 914 replacement for 'eappsk' (it can also be set using hexstring to 915 present random binary data) 916 * removed '-w' command line parameter (wait for interface to be added, 917 if needed); cleaner way of handling this functionality is to use an 918 external mechanism (e.g., hotplug scripts) that start wpa_supplicant 919 when an interface is added 920 * updated FT support to use the latest draft, IEEE 802.11r/D9.0 921 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for 922 indicating when new scan results become available 923 * added new ctrl_iface command, BSS, to allow scan results to be 924 fetched without hitting the message size limits (this command 925 can be used to iterate through the scan results one BSS at the time) 926 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION 927 attributes in EAP-SIM Start/Response when using fast reauthentication 928 * fixed EAPOL not to end up in infinite loop when processing dynamic 929 WEP keys with IEEE 802.1X 930 * fixed problems in getting NDIS events from WMI on Windows 2000 931 932 2008-01-01 - v0.6.2 933 * added support for Makefile builds to include debug-log-to-a-file 934 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line) 935 * fixed EAP-SIM and EAP-AKA message parser to validate attribute 936 lengths properly to avoid potential crash caused by invalid messages 937 * added data structure for storing allocated buffers (struct wpabuf); 938 this does not affect wpa_supplicant usage, but many of the APIs 939 changed and various interfaces (e.g., EAP) is not compatible with old 940 versions 941 * added support for protecting EAP-AKA/Identity messages with 942 AT_CHECKCODE (optional feature in RFC 4187) 943 * added support for protected result indication with AT_RESULT_IND for 944 EAP-SIM and EAP-AKA (phase1="result_ind=1") 945 * added driver_wext workaround for race condition between scanning and 946 association with drivers that take very long time to scan all 947 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now 948 using a longer hardcoded timeout for the scan if the driver supports 949 notifications for scan completion (SIOCGIWSCAN event); this helps, 950 e.g., in cases where wpa_supplicant and madwifi driver ended up in 951 loop where the driver did not even try to associate 952 * stop EAPOL timer tick when no timers are in use in order to reduce 953 power consumption (no need to wake up the process once per second) 954 [Bug 237] 955 * added support for privilege separation (run only minimal part of 956 wpa_supplicant functionality as root and rest as unprivileged, 957 non-root process); see 'Privilege separation' in README for details; 958 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y 959 in .config 960 * changed scan results data structure to include all information 961 elements to make it easier to support new IEs; old get_scan_result() 962 driver_ops is still supported for backwards compatibility (results 963 are converted internally to the new format), but all drivers should 964 start using the new get_scan_results2() to make them more likely to 965 work with new features 966 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4 967 application, i.e., it does not require Qt3Support anymore; Windows 968 binary of wpa_gui.exe is now from this directory and only requires 969 QtCore4.dll and QtGui4.dll libraries 970 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs 971 available as a separate package to make wpa_gui installation easier: 972 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip 973 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt); 974 only shared key/password authentication is supported in this version 975 976 2007-11-24 - v0.6.1 977 * added support for configuring password as NtPasswordHash 978 (16-byte MD4 hash of password) in hash:<32 hex digits> format 979 * added support for fallback from abbreviated TLS handshake to 980 full handshake when using EAP-FAST (e.g., due to an expired 981 PAC-Opaque) 982 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 983 draft (draft-ietf-emu-eap-gpsk-07.txt) 984 * added support for drivers that take care of RSN 4-way handshake 985 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and 986 WPA_ALG_PMK in set_key) 987 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in 988 .config); this version supports only ap_scan=2 mode and allow the 989 driver to take care of the 4-way handshake 990 * fixed a buffer overflow in parsing TSF from scan results when using 991 driver_wext.c with a driver that includes the TSF (e.g., iwl4965) 992 [Bug 232] 993 * updated FT support to use the latest draft, IEEE 802.11r/D8.0 994 * fixed an integer overflow issue in the ASN.1 parser used by the 995 (experimental) internal TLS implementation to avoid a potential 996 buffer read overflow 997 * fixed a race condition with -W option (wait for a control interface 998 monitor before starting) that could have caused the first messages to 999 be lost 1000 * added support for processing TNCC-TNCS-Messages to report 1001 recommendation (allow/none/isolate) when using TNC [Bug 243] 1002 1003 2007-05-28 - v0.6.0 1004 * added network configuration parameter 'frequency' for setting 1005 initial channel for IBSS (adhoc) networks 1006 * added experimental IEEE 802.11r/D6.0 support 1007 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48 1008 * updated EAP-PSK to use the IANA-allocated EAP type 47 1009 * fixed EAP-PAX key derivation 1010 * fixed EAP-PSK bit ordering of the Flags field 1011 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in 1012 tunnelled identity request (previously, the identifier from the outer 1013 method was used, not the tunnelled identifier which could be 1014 different) 1015 * added support for fragmentation of outer TLS packets during Phase 2 1016 of EAP-PEAP/TTLS/FAST 1017 * fixed EAP-TTLS AVP parser processing for too short AVP lengths 1018 * added support for EAP-FAST authentication with inner methods that 1019 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported 1020 for PAC provisioning) 1021 * added support for authenticated EAP-FAST provisioning 1022 * added support for configuring maximum number of EAP-FAST PACs to 1023 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string) 1024 * added support for storing EAP-FAST PACs in binary format 1025 (fast_pac_format=binary in phase1 string) 1026 * fixed dbus ctrl_iface to validate message interface before 1027 dispatching to avoid a possible segfault [Bug 190] 1028 * fixed PeerKey key derivation to use the correct PRF label 1029 * updated Windows binary build to link against OpenSSL 0.9.8d and 1030 added support for EAP-FAST 1031 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 1032 draft (draft-ietf-emu-eap-gpsk-04.txt) 1033 * fixed EAP-AKA Notification processing to allow Notification to be 1034 processed after AKA Challenge response has been sent 1035 * updated to use IEEE 802.11w/D2.0 for management frame protection 1036 (still experimental) 1037 * fixed EAP-TTLS implementation not to crash on use of freed memory 1038 if TLS library initialization fails 1039 * added support for EAP-TNC (Trusted Network Connect) 1040 (this version implements the EAP-TNC method and EAP-TTLS changes 1041 needed to run two methods in sequence (IF-T) and the IF-IMC and 1042 IF-TNCCS interfaces from TNCC) 1043 1044 2006-11-24 - v0.5.6 1045 * added experimental, integrated TLSv1 client implementation with the 1046 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by 1047 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in 1048 .config); this can be useful, e.g., if the target system does not 1049 have a suitable TLS library and a minimal code size is required 1050 (total size of this internal TLS/crypto code is bit under 50 kB on 1051 x86 and the crypto code is shared by rest of the supplicant so some 1052 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB) 1053 * removed STAKey handshake since PeerKey handshake has replaced it in 1054 IEEE 802.11ma and there are no known deployments of STAKey 1055 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 1056 draft (draft-ietf-emu-eap-gpsk-01.txt) 1057 * added preliminary implementation of IEEE 802.11w/D1.0 (management 1058 frame protection) 1059 (Note: this requires driver support to work properly.) 1060 (Note2: IEEE 802.11w is an unapproved draft and subject to change.) 1061 * fixed Windows named pipes ctrl_iface to not stop listening for 1062 commands if client program opens a named pipe and closes it 1063 immediately without sending a command 1064 * fixed USIM PIN status determination for the case that PIN is not 1065 needed (this allows EAP-AKA to be used with USIM cards that do not 1066 use PIN) 1067 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to 1068 be used with cards that do not support file selection based on 1069 partial AID 1070 * added support for matching the subjectAltName of the authentication 1071 server certificate against multiple name components (e.g., 1072 altsubject_match="DNS:server.example.com;DNS:server2.example.com") 1073 * fixed EAP-SIM/AKA key derivation for re-authentication case (only 1074 affects IEEE 802.1X with dynamic WEP keys) 1075 * changed ctrl_iface network configuration 'get' operations to not 1076 return password/key material; if these fields are requested, "*" 1077 will be returned if the password/key is set, but the value of the 1078 parameter is not exposed 1079 1080 2006-08-27 - v0.5.5 1081 * added support for building Windows version with UNICODE defined 1082 (wide-char functions) 1083 * driver_ndis: fixed static WEP configuration to avoid race condition 1084 issues with some NDIS drivers between association and setting WEP 1085 keys 1086 * driver_ndis: added validation for IELength value in scan results to 1087 avoid crashes when using buggy NDIS drivers [Bug 165] 1088 * fixed Release|Win32 target in the Visual Studio project files 1089 (previously, only Debug|Win32 target was set properly) 1090 * changed control interface API call wpa_ctrl_pending() to allow it to 1091 return -1 on error (e.g., connection lost); control interface clients 1092 will need to make sure that they verify that the value is indeed >0 1093 when determining whether there are pending messages 1094 * added an alternative control interface backend for Windows targets: 1095 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default 1096 control interface mechanism for Windows builds (previously, UDP to 1097 localhost was used) 1098 * changed ctrl_interface configuration for UNIX domain sockets: 1099 - deprecated ctrl_interface_group variable (it may be removed in 1100 future versions) 1101 - allow both directory and group be configured with ctrl_interface 1102 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel 1103 - ctrl_interface=/var/run/wpa_supplicant is still supported for the 1104 case when group is not changed 1105 * added support for controlling more than one interface per process in 1106 Windows version 1107 * added a workaround for a case where the AP is using unknown address 1108 (e.g., MAC address of the wired interface) as the source address for 1109 EAPOL-Key frames; previously, that source address was used as the 1110 destination for EAPOL-Key frames and in key derivation; now, BSSID is 1111 used even if the source address does not match with it 1112 (this resolves an interoperability issue with Thomson SpeedTouch 580) 1113 * added a workaround for UDP-based control interface (which was used in 1114 Windows builds before this release) to prevent packets with forged 1115 addresses from being accepted as local control requests 1116 * removed ndis_events.cpp and possibility of using external 1117 ndis_events.exe; C version (ndis_events.c) is fully functional and 1118 there is no desire to maintain two separate versions of this 1119 implementation 1120 * ndis_events: Changed NDIS event notification design to use WMI to 1121 learn the adapter description through Win32_PnPEntity class; this 1122 should fix some cases where the adapter name was not recognized 1123 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500 1124 USB) [Bug 113] 1125 * fixed selection of the first network in ap_scan=2 mode; previously, 1126 wpa_supplicant could get stuck in SCANNING state when only the first 1127 network for enabled (e.g., after 'wpa_cli select_network 0') 1128 * winsvc: added support for configuring ctrl_interface parameters in 1129 registry (ctrl_interface string value in 1130 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is 1131 required to enable control interface (previously, this was hardcoded 1132 to be enabled) 1133 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4 1134 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format 1135 1136 2006-06-20 - v0.5.4 1137 * fixed build with CONFIG_STAKEY=y [Bug 143] 1138 * added support for doing MLME (IEEE 802.11 management frame 1139 processing) in wpa_supplicant when using Devicescape IEEE 802.11 1140 stack (wireless-dev.git tree) 1141 * added a new network block configuration option, fragment_size, to 1142 configure the maximum EAP fragment size 1143 * driver_ndis: Disable WZC automatically for the selected interface to 1144 avoid conflicts with two programs trying to control the radio; WZC 1145 will be re-enabled (if it was enabled originally) when wpa_supplicant 1146 is terminated 1147 * added an experimental TLSv1 client implementation 1148 (CONFIG_TLS=internal) that can be used instead of an external TLS 1149 library, e.g., to reduce total size requirement on systems that do 1150 not include any TLS library by default (this is not yet complete; 1151 basic functionality is there, but certificate validation is not yet 1152 included) 1153 * added PeerKey handshake implementation for IEEE 802.11e 1154 direct link setup (DLS) to replace STAKey handshake 1155 * fixed WPA PSK update through ctrl_iface for the case where the old 1156 PSK was derived from an ASCII passphrase and the new PSK is set as 1157 a raw PSK (hex string) 1158 * added new configuration option for identifying which network block 1159 was used (id_str in wpa_supplicant.conf; included on 1160 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental 1161 variable in wpa_cli action scripts; in addition WPA_ID variable is 1162 set to the current unique identifier that wpa_supplicant assigned 1163 automatically for the network and that can be used with 1164 GET_NETWORK/SET_NETWORK ctrl_iface commands) 1165 * wpa_cli action script is now called only when the connect/disconnect 1166 status changes or when associating with a different network 1167 * fixed configuration parser not to remove CCMP from group cipher list 1168 if WPA-None (adhoc) is used (pairwise=NONE in that case) 1169 * fixed integrated NDIS events processing not to hang the process due 1170 to a missed change in eloop_win.c API in v0.5.3 [Bug 155] 1171 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK, 1172 draft-clancy-emu-eap-shared-secret-00.txt) 1173 * added Microsoft Visual Studio 2005 solution and project files for 1174 build wpa_supplicant for Windows (see vs2005 subdirectory) 1175 * eloop_win: fixed unregistration of Windows events 1176 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet 1177 at the end of RSN pre-authentication and added unregistration of 1178 a Windows event to avoid getting eloop_win stuck with an invalid 1179 handle 1180 * driver_ndis: added support for selecting AP based on BSSID 1181 * added new environmental variable for wpa_cli action scripts: 1182 WPA_CTRL_DIR is the current control interface directory 1183 * driver_ndis: added support for using NDISUIO instead of WinPcap for 1184 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new 1185 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build 1186 wpa_supplicant without requiring WinPcap; note that using NDISUIO 1187 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows 1188 only one application to open the device 1189 * changed NDIS driver naming to only include device GUID, e.g., 1190 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap 1191 specific \Device\NPF_ prefix before the GUID; the prefix is still 1192 allowed for backwards compatibility, but it is not required anymore 1193 when specifying the interface 1194 * driver_ndis: re-initialize driver interface is the adapter is removed 1195 and re-inserted [Bug 159] 1196 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on 1197 big endian hosts [Bug 146] 1198 1199 2006-04-27 - v0.5.3 1200 * fixed EAP-GTC response to include correct user identity when run as 1201 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2) 1202 * driver_ndis: Fixed encryption mode configuration for unencrypted 1203 networks (some NDIS drivers ignored this, but others, e.g., Broadcom, 1204 refused to associate with open networks) [Bug 106] 1205 * driver_ndis: use BSSID OID polling to detect when IBSS network is 1206 formed even when ndis_events code is included since some NDIS drivers 1207 do not generate media connect events in IBSS mode 1208 * config_winreg: allow global ctrl_interface parameter to be configured 1209 in Windows registry 1210 * config_winreg: added support for saving configuration data into 1211 Windows registry 1212 * added support for controlling network device operational state 1213 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see 1214 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client 1215 that can use this information) 1216 * driver_wext: added support for WE-21 change to SSID configuration 1217 * driver_wext: fixed privacy configuration for static WEP keys mode 1218 [Bug 140] 1219 * added an optional driver_ops callback for MLME-SETPROTECTION.request 1220 primitive 1221 * added support for EAP-SAKE (no EAP method number allocated yet, so 1222 this is using the same experimental type 255 as EAP-PSK) 1223 * added support for dynamically loading EAP methods (.so files) instead 1224 of requiring them to be statically linked in; this is disabled by 1225 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information 1226 on how to use this) 1227 1228 2006-03-19 - v0.5.2 1229 * do not try to use USIM APDUs when initializing PC/SC for SIM card 1230 access for a network that has not enabled EAP-AKA 1231 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in 1232 v0.5.1 due to the new support for expanded EAP types) 1233 * added support for generating EAP Expanded Nak 1234 * try to fetch scan results once before requesting new scan when 1235 starting up in ap_scan=1 mode (this can speed up initial association 1236 a lot with, e.g., madwifi-ng driver) 1237 * added support for receiving EAPOL frames from a Linux bridge 1238 interface (-bbr0 on command line) 1239 * fixed EAPOL re-authentication for sessions that used PMKSA caching 1240 * changed EAP method registration to use a dynamic list of methods 1241 instead of a static list generated at build time 1242 * fixed PMKSA cache deinitialization not to use freed memory when 1243 removing PMKSA entries 1244 * fixed a memory leak in EAP-TTLS re-authentication 1245 * reject WPA/WPA2 message 3/4 if it does not include any valid 1246 WPA/RSN IE 1247 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg 1248 if the driver does not support SIOCSIWAUTH 1249 1250 2006-01-29 - v0.5.1 1251 * driver_test: added better support for multiple APs and STAs by using 1252 a directory with sockets that include MAC address for each device in 1253 the name (driver_param=test_dir=/tmp/test) 1254 * added support for EAP expanded type (vendor specific EAP methods) 1255 * added AP_SCAN command into ctrl_iface so that ap_scan configuration 1256 option can be changed if needed 1257 * wpa_cli/wpa_gui: skip non-socket files in control directory when 1258 using UNIX domain sockets; this avoids selecting an incorrect 1259 interface (e.g., a PID file could be in this directory, even though 1260 use of this directory for something else than socket files is not 1261 recommended) 1262 * fixed TLS library deinitialization after RSN pre-authentication not 1263 to disable TLS library for normal authentication 1264 * driver_wext: Remove null-termination from SSID length if the driver 1265 used it; some Linux drivers do this and they were causing problems in 1266 wpa_supplicant not finding matching configuration block. This change 1267 would break a case where the SSID actually ends in '\0', but that is 1268 not likely to happen in real use. 1269 * fixed PMKSA cache processing not to trigger deauthentication if the 1270 current PMKSA cache entry is replaced with a valid new entry 1271 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes 1272 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or 1273 ap_scan=2) 1274 1275 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases) 1276 * added experimental STAKey handshake implementation for IEEE 802.11e 1277 direct link setup (DLS); note: this is disabled by default in both 1278 build and runtime configuration (can be enabled with CONFIG_STAKEY=y 1279 and stakey=1) 1280 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to 1281 decrypt AT_ENCR_DATA attributes correctly 1282 * fixed EAP-AKA to allow resynchronization within the same session 1283 * made code closer to ANSI C89 standard to make it easier to port to 1284 other C libraries and compilers 1285 * started moving operating system or C library specific functions into 1286 wrapper functions defined in os.h and implemented in os_*.c to make 1287 code more portable 1288 * wpa_supplicant can now be built with Microsoft Visual C++ 1289 (e.g., with the freely available Toolkit 2003 version or Visual 1290 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an 1291 example makefile for nmake 1292 * added support for using Windows registry for command line parameters 1293 (CONFIG_MAIN=main_winsvc) and configuration data 1294 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry 1295 contents; this version can be run both as a Windows service and as a 1296 normal application; 'wpasvc.exe app' to start as applicant, 1297 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service, 1298 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to 1299 unregister a service 1300 * made it possible to link ndis_events.exe functionality into 1301 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED 1302 * added better support for multiple control interface backends 1303 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported 1304 * fixed PC/SC code to use correct length for GSM AUTH command buffer 1305 and to not use pioRecvPci with SCardTransmit() calls; these were not 1306 causing visible problems with pcsc-lite, but Windows Winscard.dll 1307 refused the previously used parameters; this fixes EAP-SIM and 1308 EAP-AKA authentication using SIM/USIM card under Windows 1309 * added new event loop implementation for Windows using 1310 WaitForMultipleObject() instead of select() in order to allow waiting 1311 for non-socket objects; this can be selected with 1312 CONFIG_ELOOP=eloop_win in .config 1313 * added support for selecting l2_packet implementation in .config 1314 (CONFIG_L2_PACKET; following options are available now: linux, pcap, 1315 winpcap, freebsd, none) 1316 * added new l2_packet implementation for WinPcap 1317 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to 1318 reduce latency in EAPOL receive processing from about 100 ms to about 1319 3 ms 1320 * added support for EAP-FAST key derivation using other ciphers than 1321 RC4-128-SHA for authentication and AES128-SHA for provisioning 1322 * added support for configuring CA certificate as DER file and as a 1323 configuration blob 1324 * fixed private key configuration as configuration blob and added 1325 support for using PKCS#12 as a blob 1326 * tls_gnutls: added support for using PKCS#12 files; added support for 1327 session resumption 1328 * added support for loading trusted CA certificates from Windows 1329 certificate store: ca_cert="cert_store://<name>", where <name> is 1330 likely CA (Intermediate CA certificates) or ROOT (root certificates) 1331 * added C version of ndis_events.cpp and made it possible to build this 1332 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more 1333 easily on cross-compilation builds 1334 * added wpasvc.exe into Windows binary release; this is an alternative 1335 version of wpa_supplicant.exe with configuration backend using 1336 Windows registry and with the entry point designed to run as a 1337 Windows service 1338 * integrated ndis_events.exe functionality into wpa_supplicant.exe and 1339 wpasvc.exe and removed this additional tool from the Windows binary 1340 release since it is not needed anymore 1341 * load winscard.dll functions dynamically when building with MinGW 1342 since MinGW does not yet include winscard library 1343 1344 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases) 1345 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap 1346 and WinPcap to receive frames sent to PAE group address 1347 * disable EAP state machine when IEEE 802.1X authentication is not used 1348 in order to get rid of bogus "EAP failed" messages 1349 * fixed OpenSSL error reporting to go through all pending errors to 1350 avoid confusing reports of old errors being reported at later point 1351 during handshake 1352 * fixed configuration file updating to not write empty variables 1353 (e.g., proto or key_mgmt) that the file parser would not accept 1354 * fixed ADD_NETWORK ctrl_iface command to use the same default values 1355 for variables as empty network definitions read from config file 1356 would get 1357 * fixed EAP state machine to not discard EAP-Failure messages in many 1358 cases (e.g., during TLS handshake) 1359 * fixed a infinite loop in private key reading if the configured file 1360 cannot be parsed successfully 1361 * driver_madwifi: added support for madwifi-ng 1362 * wpa_gui: do not display password/PSK field contents 1363 * wpa_gui: added CA certificate configuration 1364 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID 1365 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if 1366 the new AP is using different WPA/RSN IE 1367 * use longer timeout for IEEE 802.11 association to avoid problems with 1368 drivers that may take more than five second to associate 1369 1370 2005-10-27 - v0.4.6 1371 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in 1372 RSN IE, but WPA IE would match with wpa_supplicant configuration 1373 * added support for named configuration blobs in order to avoid having 1374 to use file system for external files (e.g., certificates); 1375 variables can be set to "blob://<blob name>" instead of file path to 1376 use a named blob; supported fields: pac_file, client_cert, 1377 private_key 1378 * fixed RSN pre-authentication (it was broken in the clean up of WPA 1379 state machine interface in v0.4.5) 1380 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make 1381 sure the driver configures broadcast decryption correctly 1382 * added ca_path (and ca_path2) configuration variables that can be used 1383 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the 1384 system-wide trusted CA list 1385 * added support for starting wpa_supplicant without a configuration 1386 file (-C argument must be used to set ctrl_interface parameter for 1387 this case; in addition, -p argument can be used to provide 1388 driver_param; these new arguments can also be used with a 1389 configuration to override the values from the configuration) 1390 * added global control interface that can be optionally used for adding 1391 and removing network interfaces dynamically (-g command line argument 1392 for both wpa_supplicant and wpa_cli) without having to restart 1393 wpa_supplicant process 1394 * wpa_gui: 1395 - try to save configuration whenever something is modified 1396 - added WEP key configuration 1397 - added possibility to edit the current network configuration 1398 * driver_ndis: fixed driver polling not to increase frequency on each 1399 received EAPOL frame due to incorrectly cancelled timeout 1400 * added simple configuration file examples (in examples subdirectory) 1401 * fixed driver_wext.c to filter wireless events based on ifindex to 1402 avoid interfaces receiving events from other interfaces 1403 * delay sending initial EAPOL-Start couple of seconds to speed up 1404 authentication for the most common case of Authenticator starting 1405 EAP authentication immediately after association 1406 1407 2005-09-25 - v0.4.5 1408 * added a workaround for clearing keys with ndiswrapper to allow 1409 roaming from WPA enabled AP to plaintext one 1410 * added docbook documentation (doc/docbook) that can be used to 1411 generate, e.g., man pages 1412 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for 1413 PF_PACKET in order to prepare for network devices that do not use 1414 Ethernet headers (e.g., network stack with native IEEE 802.11 frames) 1415 * use receipt of EAPOL-Key frame as a lower layer success indication 1416 for EAP state machine to allow recovery from dropped EAP-Success 1417 frame 1418 * cleaned up internal EAPOL frame processing by not including link 1419 layer (Ethernet) header during WPA and EAPOL/EAP processing; this 1420 header is added only when transmitted the frame; this makes it easier 1421 to use wpa_supplicant on link layers that use different header than 1422 Ethernet 1423 * updated EAP-PSK to use draft 9 by default since this can now be 1424 tested with hostapd; removed support for draft 3, including 1425 server_nai configuration option from network blocks 1426 * driver_wired: add PAE address to the multicast address list in order 1427 to be able to receive EAPOL frames with drivers that do not include 1428 these multicast addresses by default 1429 * driver_wext: add support for WE-19 1430 * added support for multiple configuration backends (CONFIG_BACKEND 1431 option); currently, only 'file' is supported (i.e., the format used 1432 in wpa_supplicant.conf) 1433 * added support for updating configuration ('wpa_cli save_config'); 1434 this is disabled by default and can be enabled with global 1435 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli 1436 and wpa_gui to store the configuration changes in a permanent store 1437 * added GET_NETWORK ctrl_iface command 1438 (e.g., 'wpa_cli get_network 0 ssid') 1439 1440 2005-08-21 - v0.4.4 1441 * replaced OpenSSL patch for EAP-FAST support 1442 (openssl-tls-extensions.patch) with a more generic and correct 1443 patch (the new patch is not compatible with the previous one, so the 1444 OpenSSL library will need to be patched with the new patch in order 1445 to be able to build wpa_supplicant with EAP-FAST support) 1446 * added support for using Windows certificate store (through CryptoAPI) 1447 for client certificate and private key operations (EAP-TLS) 1448 (see wpa_supplicant.conf for more information on how to configure 1449 this with private_key) 1450 * ported wpa_gui to Windows 1451 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be 1452 built with the open source version of the Qt4 for Windows 1453 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used 1454 with drivers that do not support WPA 1455 * ndis_events: fixed Windows 2000 support 1456 * added support for enabling/disabling networks from the list of all 1457 configured networks ('wpa_cli enable_network <network id>' and 1458 'wpa_cli disable_network <network id>') 1459 * added support for adding and removing network from the current 1460 configuration ('wpa_cli add_network' and 'wpa_cli remove_network 1461 <network id>'); added networks are disabled by default and they can 1462 be enabled with enable_network command once the configuration is done 1463 for the new network; note: configuration file is not yet updated, so 1464 these new networks are lost when wpa_supplicant is restarted 1465 * added support for setting network configuration parameters through 1466 the control interface, for example: 1467 wpa_cli set_network 0 ssid "\"my network\"" 1468 * fixed parsing of strings that include both " and # within double 1469 quoted area (e.g., "start"#end") 1470 * added EAP workaround for PEAP session resumption: allow outer, 1471 i.e., not tunneled, EAP-Success to terminate session since; this can 1472 be disabled with eap_workaround=0 1473 (this was allowed for PEAPv1 before, but now it is also allowed for 1474 PEAPv0 since at least one RADIUS authentication server seems to be 1475 doing this for PEAPv0, too) 1476 * wpa_gui: added preliminary support for adding new networks to the 1477 wpa_supplicant configuration (double click on the scan results to 1478 open network configuration) 1479 1480 2005-06-26 - v0.4.3 1481 * removed interface for external EAPOL/EAP supplicant (e.g., 1482 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required 1483 anymore and is unlikely to be used by anyone 1484 * driver_ndis: fixed WinPcap 3.0 support 1485 * fixed build with CONFIG_DNET_PCAP=y on Linux 1486 * l2_packet: moved different implementations into separate files 1487 (l2_packet_*.c) 1488 1489 2005-06-12 - v0.4.2 1490 * driver_ipw: updated driver structures to match with ipw2200-1.0.4 1491 (note: ipw2100-1.1.0 is likely to require an update to work with 1492 this) 1493 * added support for using ap_scan=2 mode with multiple network blocks; 1494 wpa_supplicant will go through the networks one by one until the 1495 driver reports a successful association; this uses the same order for 1496 networks as scan_ssid=1 scans, i.e., the priority field is ignored 1497 and the network block order in the file is used instead 1498 * fixed a potential issue in RSN pre-authentication ending up using 1499 freed memory if pre-authentication times out 1500 * added support for matching alternative subject name extensions of the 1501 authentication server certificate; new configuration variables 1502 altsubject_match and altsubject_match2 1503 * driver_ndis: added support for IEEE 802.1X authentication with wired 1504 NDIS drivers 1505 * added support for querying private key password (EAP-TLS) through the 1506 control interface (wpa_cli/wpa_gui) if one is not included in the 1507 configuration file 1508 * driver_broadcom: fixed couple of memory leaks in scan result 1509 processing 1510 * EAP-PAX is now registered as EAP type 46 1511 * fixed EAP-PAX MAC calculation 1512 * fixed EAP-PAX CK and ICK key derivation 1513 * added support for using password with EAP-PAX (as an alternative to 1514 entering key with eappsk); SHA-1 hash of the password will be used as 1515 the key in this case 1516 * added support for arbitrary driver interface parameters through the 1517 configuration file with a new driver_param field; this adds a new 1518 driver_ops function set_param() 1519 * added possibility to override l2_packet module with driver interface 1520 API (new send_eapol handler); this can be used to implement driver 1521 specific TX/RX functions for EAPOL frames 1522 * fixed ctrl_interface_group processing for the case where gid is 1523 entered as a number, not group name 1524 * driver_test: added support for testing hostapd with wpa_supplicant 1525 by using test driver interface without any kernel drivers or network 1526 cards 1527 1528 2005-05-22 - v0.4.1 1529 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL 1530 packets to be encrypted; this was apparently broken by the changed 1531 ioctl order in v0.4.0 1532 * driver_madwifi: added preliminary support for compiling against 'BSD' 1533 branch of madwifi CVS tree 1534 * added support for EAP-MSCHAPv2 password retries within the same EAP 1535 authentication session 1536 * added support for password changes with EAP-MSCHAPv2 (used when the 1537 password has expired) 1538 * added support for reading additional certificates from PKCS#12 files 1539 and adding them to the certificate chain 1540 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys 1541 were used 1542 * fixed a possible double free in EAP-TTLS fast-reauthentication when 1543 identity or password is entered through control interface 1544 * display EAP Notification messages to user through control interface 1545 with "CTRL-EVENT-EAP-NOTIFICATION" prefix 1546 * added GUI version of wpa_cli, wpa_gui; this is not build 1547 automatically with 'make'; use 'make wpa_gui' to build (this requires 1548 Qt development tools) 1549 * added 'disconnect' command to control interface for setting 1550 wpa_supplicant in state where it will not associate before 1551 'reassociate' command has been used 1552 * added support for selecting a network from the list of all configured 1553 networks ('wpa_cli select_network <network id>'; this disabled all 1554 other networks; to re-enable, 'wpa_cli select_network any') 1555 * added support for getting scan results through control interface 1556 * added EAP workaround for PEAPv1 session resumption: allow outer, 1557 i.e., not tunneled, EAP-Success to terminate session since; this can 1558 be disabled with eap_workaround=0 1559 1560 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases) 1561 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be 1562 used to reduce the size of the wpa_supplicant considerably if 1563 debugging code is not needed 1564 * fixed EAPOL-Key validation to drop packets with invalid Key Data 1565 Length; such frames could have crashed wpa_supplicant due to buffer 1566 overflow 1567 * added support for wired authentication (IEEE 802.1X on wired 1568 Ethernet); driver interface 'wired' 1569 * obsoleted set_wpa() handler in the driver interface API (it can be 1570 replaced by moving enable/disable functionality into init()/deinit()) 1571 (calls to set_wpa() are still present for backwards compatibility, 1572 but they may be removed in the future) 1573 * driver_madwifi: fixed association in plaintext mode 1574 * modified the EAP workaround that accepts EAP-Success with incorrect 1575 Identifier to be even less strict about verification in order to 1576 interoperate with some authentication servers 1577 * added support for sending TLS alerts 1578 * added support for 'any' SSID wildcard; if ssid is not configured or 1579 is set to an empty string, any SSID will be accepted for non-WPA AP 1580 * added support for asking PIN (for SIM) from frontends (e.g., 1581 wpa_cli); if a PIN is needed, but not included in the configuration 1582 file, a control interface request is sent and EAP processing is 1583 delayed until the PIN is available 1584 * added support for using external devices (e.g., a smartcard) for 1585 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config); 1586 new wpa_supplicant.conf variables: 1587 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path 1588 - network: engine, engine_id, key_id 1589 * added experimental support for EAP-PAX 1590 * added monitor mode for wpa_cli (-a<path to a program to run>) that 1591 allows external commands (e.g., shell scripts) to be run based on 1592 wpa_supplicant events, e.g., when authentication has been completed 1593 and data connection is ready; other related wpa_cli arguments: 1594 -B (run in background), -P (write PID file); wpa_supplicant has a new 1595 command line argument (-W) that can be used to make it wait until a 1596 control interface command is received in order to avoid missing 1597 events 1598 * added support for opportunistic WPA2 PMKSA key caching (disabled by 1599 default, can be enabled with proactive_key_caching=1) 1600 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where 1601 Authenticator rejects PMKSA caching attempt and the driver is not 1602 using assoc_info events 1603 * added -P<pid file> argument for wpa_supplicant to write the current 1604 process id into a file 1605 1606 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases) 1607 * added new phase1 option parameter, include_tls_length=1, to force 1608 wpa_supplicant to add TLS Message Length field to all TLS messages 1609 even if the packet is not fragmented; this may be needed with some 1610 authentication servers 1611 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when 1612 using drivers that take care of AP selection (e.g., when using 1613 ap_scan=2) 1614 * fixed reprocessing of pending request after ctrl_iface requests for 1615 identity/password/otp 1616 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of 1617 EAP-PEAP and EAP-TTLS 1618 * all drivers using driver_wext: set interface up and select Managed 1619 mode when starting wpa_supplicant; set interface down when exiting 1620 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both 1621 ipw2100 and ipw2200; please note that this also changed the 1622 configuration variable in .config to CONFIG_DRIVER_IPW 1623 1624 2005-01-24 - v0.3.6 1625 * fixed a busy loop introduced in v0.3.5 for scan result processing 1626 when no matching AP is found 1627 1628 2005-01-23 - v0.3.5 1629 * added a workaround for an interoperability issue with a Cisco AP 1630 when using WPA2-PSK 1631 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as 1632 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow 1633 retransmission of dropped frames) 1634 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version 1635 (e.g., segfault when processing EAPOL-Key frames) 1636 * fixed EAP workaround and fast reauthentication configuration for 1637 RSN pre-authentication; previously these were disabled and 1638 pre-authentication would fail if the used authentication server 1639 requires EAP workarounds 1640 * added support for blacklisting APs that fail or timeout 1641 authentication in ap_scan=1 mode so that all APs are tried in cases 1642 where the ones with strongest signal level are failing authentication 1643 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS 1644 authentication attempt 1645 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded 1646 in the previous authentication (previously, only Phase 1 success was 1647 verified) 1648 1649 2005-01-09 - v0.3.4 1650 * added preliminary support for IBSS (ad-hoc) mode configuration 1651 (mode=1 in network block); this included a new key_mgmt mode 1652 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no 1653 key management; see wpa_supplicant.conf for more details and an 1654 example on how to configure this (note: this is currently implemented 1655 only for driver_hostapd.c, but the changes should be trivial to add 1656 in associate() handler for other drivers, too (assuming the driver 1657 supports WPA-None) 1658 * added preliminary port for native Windows (i.e., no cygwin) using 1659 mingw 1660 1661 2005-01-02 - v0.3.3 1662 * added optional support for GNU Readline and History Libraries for 1663 wpa_cli (CONFIG_READLINE) 1664 * cleaned up EAP state machine <-> method interface and number of 1665 small problems with error case processing not terminating on 1666 EAP-Failure but waiting for timeout 1667 * added couple of workarounds for interoperability issues with a 1668 Cisco AP when using WPA2 1669 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt); 1670 Note: This requires a patch for openssl to add support for TLS 1671 extensions and number of workarounds for operations without 1672 certificates. Proof of concept type of experimental patch is 1673 included in openssl-tls-extensions.patch. 1674 1675 2004-12-19 - v0.3.2 1676 * fixed private key loading for cases where passphrase is not set 1677 * fixed Windows/cygwin L2 packet handler freeing; previous version 1678 could cause a segfault when RSN pre-authentication was completed 1679 * added support for PMKSA caching with drivers that generate RSN IEs 1680 (e.g., NDIS); currently, this is only implemented in driver_ndis.c, 1681 but similar code can be easily added to driver_ndiswrapper.c once 1682 ndiswrapper gets full support for RSN PMKSA caching 1683 * improved recovery from PMKID mismatches by requesting full EAP 1684 authentication in case of failed PMKSA caching attempt 1685 * driver_ndis: added support for NDIS NdisMIncidateStatus() events 1686 (this requires that ndis_events is ran while wpa_supplicant is 1687 running) 1688 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys 1689 * added support for driver interfaces to replace the interface name 1690 based on driver/OS specific mapping, e.g., in case of driver_ndis, 1691 this allows the beginning of the adapter description to be used as 1692 the interface name 1693 * added support for CR+LF (Windows-style) line ends in configuration 1694 file 1695 * driver_ndis: enable radio before starting scanning, disable radio 1696 when exiting 1697 * modified association event handler to set portEnabled = FALSE before 1698 clearing port Valid in order to reset EAP state machine and avoid 1699 problems with new authentication getting ignored because of state 1700 machines ending up in AUTHENTICATED/SUCCESS state based on old 1701 information 1702 * added support for driver events to add PMKID candidates in order to 1703 allow drivers to give priority to most likely roaming candidates 1704 * driver_hostap: moved PrivacyInvoked configuration to associate() 1705 function so that this will not be set for plaintext connections 1706 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver 1707 interface can distinguish plaintext and IEEE 802.1X (no WPA) 1708 authentication 1709 * fixed static WEP key configuration to use broadcast/default type for 1710 all keys (previously, the default TX key was configured as pairwise/ 1711 unicast key) 1712 * driver_ndis: added legacy WPA capability detection for non-WPA2 1713 drivers 1714 * added support for setting static WEP keys for IEEE 802.1X without 1715 dynamic WEP keying (eapol_flags=0) 1716 1717 2004-12-12 - v0.3.1 1718 * added support for reading PKCS#12 (PFX) files (as a replacement for 1719 PEM/DER) to get certificate and private key (CONFIG_PKCS12) 1720 * fixed compilation with CONFIG_PCSC=y 1721 * added new ap_scan mode, ap_scan=2, for drivers that take care of 1722 association, but need to be configured with security policy and SSID, 1723 e.g., ndiswrapper and NDIS driver; this mode should allow such 1724 drivers to work with hidden SSIDs and optimized roaming; when 1725 ap_scan=2 is used, only the first network block in the configuration 1726 file is used and this configuration should have explicit security 1727 policy (i.e., only one option in the lists) for key_mgmt, pairwise, 1728 group, proto variables 1729 * added experimental port of wpa_supplicant for Windows 1730 - driver_ndis.c driver interface (NDIS OIDs) 1731 - currently, this requires cygwin and WinPcap 1732 - small utility, win_if_list, can be used to get interface name 1733 * control interface can now be removed at build time; add 1734 CONFIG_CTRL_IFACE=y to .config to maintain old functionality 1735 * optional Xsupplicant interface can now be removed at build time; 1736 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back) 1737 * added auth_alg to driver interface associate() parameters to make it 1738 easier for drivers to configure authentication algorithm as part of 1739 the association 1740 1741 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases) 1742 * driver_broadcom: added new driver interface for Broadcom wl.o driver 1743 (a generic driver for Broadcom IEEE 802.11a/g cards) 1744 * wpa_cli: fixed parsing of -p <path> command line argument 1745 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS 1746 ACK, not tunneled EAP-Success (of which only the first byte was 1747 actually send due to a bug in previous code); this seems to 1748 interoperate with most RADIUS servers that implements PEAPv1 1749 * PEAPv1: added support for terminating PEAP authentication on tunneled 1750 EAP-Success message; this can be configured by adding 1751 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf 1752 (some RADIUS servers require this whereas others require a tunneled 1753 reply 1754 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to 1755 the old label for key derivation; previously, the default was 1, 1756 but it looks like most existing PEAPv1 implementations use the old 1757 label which is thus more suitable default option 1758 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt) 1759 * fixed parsing of wep_tx_keyidx 1760 * added support for configuring list of allowed Phase 2 EAP types 1761 (for both EAP-PEAP and EAP-TTLS) instead of only one type 1762 * added support for configuring IEEE 802.11 authentication algorithm 1763 (auth_alg; mainly for using Shared Key authentication with static 1764 WEP keys) 1765 * added support for EAP-AKA (with UMTS SIM) 1766 * fixed couple of errors in PCSC handling that could have caused 1767 random-looking errors for EAP-SIM 1768 * added support for EAP-SIM pseudonyms and fast re-authentication 1769 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS 1770 session resumption) 1771 * added support for EAP-SIM with two challanges 1772 (phase1="sim_min_num_chal=3" can be used to require three challenges) 1773 * added support for configuring DH/DSA parameters for an ephemeral DH 1774 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters 1775 dh_file and dh_file2 (phase 2); this adds support for using DSA keys 1776 and optional DH key exchange to achieve forward secracy with RSA keys 1777 * added support for matching subject of the authentication server 1778 certificate with a substring when using EAP-TLS/PEAP/TTLS; new 1779 configuration variables subject_match and subject_match2 1780 * changed SSID configuration in driver_wext.c (used by many driver 1781 interfaces) to use ssid_len+1 as the length for SSID since some Linux 1782 drivers expect this 1783 * fixed couple of unaligned reads in scan result parsing to fix WPA 1784 connection on some platforms (e.g., ARM) 1785 * added driver interface for Intel ipw2100 driver 1786 * added support for LEAP with WPA 1787 * added support for larger scan results report (old limit was 4 kB of 1788 data, i.e., about 35 or so APs) when using Linux wireless extensions 1789 v17 or newer 1790 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start 1791 only if there is a PMKSA cache entry for the current AP 1792 * fixed error handling for case where reading of scan results fails: 1793 must schedule a new scan or wpa_supplicant will remain waiting 1794 forever 1795 * changed debug output to remove shared password/key material by 1796 default; all key information can be included with -K command line 1797 argument to match the previous behavior 1798 * added support for timestamping debug log messages (disabled by 1799 default, can be enabled with -t command line argument) 1800 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104 1801 if keys are not configured to be used; this fixes IEEE 802.1X mode 1802 with drivers that use this information to configure whether Privacy 1803 bit can be in Beacon frames (e.g., ndiswrapper) 1804 * avoid clearing driver keys if no keys have been configured since last 1805 key clear request; this seems to improve reliability of group key 1806 handshake for ndiswrapper & NDIS driver which seems to be suffering 1807 of some kind of timing issue when the keys are cleared again after 1808 association 1809 * changed driver interface API: 1810 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which 1811 version is being used (now, this is set to 2; previously, it was 1812 not defined) 1813 - pass pointer to private data structure to all calls 1814 - the new API is not backwards compatible; all in-tree driver 1815 interfaces has been converted to the new API 1816 * added support for controlling multiple interfaces (radios) per 1817 wpa_supplicant process; each interface needs to be listed on the 1818 command line (-c, -i, -D arguments) with -N as a separator 1819 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi) 1820 * added a workaround for EAP servers that incorrectly use same Id for 1821 sequential EAP packets 1822 * changed libpcap/libdnet configuration to use .config variable, 1823 CONFIG_DNET_PCAP, instead of requiring Makefile modification 1824 * improved downgrade attack detection in IE verification of msg 3/4: 1825 verify both WPA and RSN IEs, if present, not only the selected one; 1826 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or 1827 Probe Response frame, and RSN is enabled in wpa_supplicant 1828 configuration 1829 * fixed WPA msg 3/4 processing to allow Key Data field contain other 1830 IEs than just one WPA IE 1831 * added support for FreeBSD and driver interface for the BSD net80211 1832 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the 1833 required kernel mods have not yet been committed 1834 * made EAP workarounds configurable; enabled by default, can be 1835 disabled with network block option eap_workaround=0 1836 1837 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases) 1838 * resolved couple of interoperability issues with EAP-PEAPv1 and 1839 Phase 2 (inner EAP) fragment reassembly 1840 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the 1841 AP is using non-zero key index for the unicast key and key index zero 1842 for the broadcast key 1843 * driver_hostap: fixed IEEE 802.1X WEP key updates and 1844 re-authentication by allowing unencrypted EAPOL frames when not using 1845 WPA 1846 * added a new driver interface, 'wext', which uses only standard, 1847 driver independent functionality in Linux wireless extensions; 1848 currently, this can be used only for non-WPA IEEE 802.1X mode, but 1849 eventually, this is to be extended to support full WPA/WPA2 once 1850 Linux wireless extensions get support for this 1851 * added support for mode in which the driver is responsible for AP 1852 scanning and selection; this is disabled by default and can be 1853 enabled with global ap_scan=0 variable in wpa_supplicant.conf; 1854 this mode can be used, e.g., with generic 'wext' driver interface to 1855 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver 1856 supporting wireless extensions. 1857 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g., 1858 operation with an AP that does not include SSID in the Beacon frames) 1859 * added support for new EAP authentication methods: 1860 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP 1861 * added support for asking one-time-passwords from frontends (e.g., 1862 wpa_cli); this 'otp' command works otherwise like 'password' command, 1863 but the password is used only once and the frontend will be asked for 1864 a new password whenever a request from authenticator requires a 1865 password; this can be used with both EAP-OTP and EAP-GTC 1866 * changed wpa_cli to automatically re-establish connection so that it 1867 does not need to be re-started when wpa_supplicant is terminated and 1868 started again 1869 * improved user data (identity/password/otp) requests through 1870 frontends: process pending EAPOL packets after getting new 1871 information so that full authentication does not need to be 1872 restarted; in addition, send pending requests again whenever a new 1873 frontend is attached 1874 * changed control frontends to use a new directory for socket files to 1875 make it easier for wpa_cli to automatically select between interfaces 1876 and to provide access control for the control interface; 1877 wpa_supplicant.conf: ctrl_interface is now a path 1878 (/var/run/wpa_supplicant is the recommended path) and 1879 ctrl_interface_group can be used to select which group gets access to 1880 the control interface; 1881 wpa_cli: by default, try to connect to the first interface available 1882 in /var/run/wpa_supplicant; this path can be overriden with -p option 1883 and an interface can be selected with -i option (i.e., in most common 1884 cases, wpa_cli does not need to get any arguments) 1885 * added support for LEAP 1886 * added driver interface for Linux ndiswrapper 1887 * added priority option for network blocks in the configuration file; 1888 this allows networks to be grouped based on priority (the scan 1889 results are searched for matches with network blocks in this order) 1890 1891 2004-06-20 - v0.2.3 1892 * sort scan results to improve AP selection 1893 * fixed control interface socket removal for some error cases 1894 * improved scan requesting and authentication timeout 1895 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and 1896 TLS processing 1897 * PEAP version can now be forced with phase1="peapver=<ver>" 1898 (mostly for testing; by default, the highest version supported by 1899 both the Supplicant and Authentication Server is selected 1900 automatically) 1901 * added support for madwifi driver (Atheros ar521x) 1902 * added a workaround for cases where AP sets Install Tx/Rx bit for 1903 WPA Group Key messages when pairwise keys are used (without this, 1904 the Group Key would be used for Tx and the AP would drop frames 1905 from the station) 1906 * added GSM SIM/USIM interface for GSM authentication algorithm for 1907 EAP-SIM; this requires pcsc-lite 1908 * added support for ATMEL AT76C5XXx driver 1909 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator 1910 does not include key data in the EAPOL-Key frame (i.e., part of 1911 EAP keying material is used as data encryption key) 1912 * added support for using plaintext and static WEP networks 1913 (key_mgmt=NONE) 1914 1915 2004-05-31 - v0.2.2 1916 * added support for new EAP authentication methods: 1917 EAP-TTLS/EAP-MD5-Challenge 1918 EAP-TTLS/EAP-GTC 1919 EAP-TTLS/EAP-MSCHAPv2 1920 EAP-TTLS/EAP-TLS 1921 EAP-TTLS/MSCHAPv2 1922 EAP-TTLS/MSCHAP 1923 EAP-TTLS/PAP 1924 EAP-TTLS/CHAP 1925 EAP-PEAP/TLS 1926 EAP-PEAP/GTC 1927 EAP-PEAP/MD5-Challenge 1928 EAP-GTC 1929 EAP-SIM (not yet complete; needs GSM/SIM authentication interface) 1930 * added support for anonymous identity (to be used when identity is 1931 sent in plaintext; real identity will be used within TLS protected 1932 tunnel (e.g., with EAP-TTLS) 1933 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli 1934 * added support for requesting identity and password information using 1935 control interface; in other words, the password for EAP-PEAP or 1936 EAP-TTLS does not need to be included in the configuration file since 1937 a frontand (e.g., wpa_cli) can ask it from the user 1938 * improved RSN pre-authentication to use a candidate list and process 1939 all candidates from each scan; not only one per scan 1940 * fixed RSN IE and WPA IE capabilities field parsing 1941 * ignore Tx bit in GTK IE when Pairwise keys are used 1942 * avoid making new scan requests during IEEE 802.1X negotiation 1943 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant 1944 with TLS support (this replaces the included implementation with 1945 library code to save about 8 kB since the library code is needed 1946 anyway for TLS) 1947 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support 1948 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config) 1949 1950 2004-05-06 - v0.2.1 1951 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1) 1952 Supplicant 1953 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1] 1954 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf] 1955 - EAP-MD5 (cannot be used with WPA-RADIUS) 1956 [draft-ietf-eap-rfc2284bis-09.txt] 1957 - EAP-TLS [RFC 2716] 1958 - EAP-MSCHAPv2 (currently used only with EAP-PEAP) 1959 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt] 1960 [draft-kamath-pppext-eap-mschapv2-00.txt] 1961 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by 1962 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey) 1963 - new configuration file options: eap, identity, password, ca_cert, 1964 client_cert, privatekey, private_key_passwd 1965 - Xsupplicant is not required anymore, but it can be used by 1966 disabling the internal IEEE 802.1X Supplicant with -e command line 1967 option 1968 - this code is not included in the default build; Makefile need to 1969 be edited for this (uncomment lines for selected functionality) 1970 - EAP-TLS and EAP-PEAP require openssl libraries 1971 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..) 1972 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys 1973 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X 1974 EAPOL-Key frames instead of WPA key handshakes) 1975 * added support for IEEE 802.11i/RSN (WPA2) 1976 - improved PTK Key Handshake 1977 - PMKSA caching, pre-authentication 1978 * fixed wpa_supplicant to ignore possible extra data after WPA 1979 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using 1980 TPTK' error from message 3 of 4-Way Handshake in case the AP 1981 includes extra data after the EAPOL-Key) 1982 * added interface for external programs (frontends) to control 1983 wpa_supplicant 1984 - CLI example (wpa_cli) with interactive mode and command line 1985 mode 1986 - replaced SIGUSR1 status/statistics with the new control interface 1987 * made some feature compile time configurable 1988 - .config file for make 1989 - driver interfaces (hostap, hermes, ..) 1990 - EAPOL/EAP functions 1991 1992 2004-02-15 - v0.2.0 1993 * Initial version of wpa_supplicant 1994
