See README-P2P. 529 - Many WPS/WPS ER commands - see WPS/WPS ER sections for details. 530 - Allow set command to change global config parameters. 531 - Add log_level command, which can be used to display the current 532 debugging level and to change the log level during run time. 533 - Add note command, which can be used to insert notes to the debug 534 log. 535 - Add internal line edit implementation. CONFIG_WPA_CLI_EDIT=y 536 can now be used to build wpa_cli with internal implementation of 537 line editing and history support. This can be used as a replacement 538 for CONFIG_READLINE=y. 539 * AP mode: Add max_num_sta config option, which can be used to limit 540 the number of stations allowed to connect to the AP. 541 * Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad 542 config file. 543 * wext: Increase scan timeout from 5 to 10 seconds. 544 * Add blacklist command, allowing an external program to 545 manage the BSS blacklist and display its current contents. 546 * WPS: 547 - Add wpa_cli wps_pin get command for generating random PINs. This can 548 be used in a UI to generate a PIN without starting WPS (or P2P) 549 operation. 550 - Set RF bands based on driver capabilities, instead of hardcoding 551 them. 552 - Add mechanism for indicating non-standard WPS errors. 553 - Add CONFIG_WPS_REG_DISABLE_OPEN=y option to disable open networks 554 by default. 555 - Add wps_ap_pin cli command for wpa_supplicant AP mode. 556 - Add wps_check_pin cli command for processing PIN from user input. 557 UIs can use this command to process a PIN entered by a user and to 558 validate the checksum digit (if present). 559 - Cancel WPS operation on PBC session overlap detection. 560 - New wps_cancel command in wpa_cli will cancel a pending WPS 561 operation. 562 - wpa_cli action: Add WPS_EVENT_SUCCESS and WPS_EVENT_FAIL handlers. 563 - Trigger WPS config update on Manufacturer, Model Name, Model 564 Number, and Serial Number changes. 565 - Fragment size is now configurable for EAP-WSC peer. Use 566 wpa_cli set wps_fragment_size <val>. 567 - Disable AP PIN after 10 consecutive failures. Slow down attacks on 568 failures up to 10. 569 - Allow AP to start in Enrollee mode without AP PIN for probing, to 570 be compatible with Windows 7. 571 - Add Config Error into WPS-FAIL events to provide more info to the 572 user on how to resolve the issue. 573 - Label and Display config methods are not allowed to be enabled 574 at the same time, since it is unclear which PIN to use if both 575 methods are advertised. 576 - When controlling multiple interfaces: 577 - apply WPS commands to all interfaces configured to use WPS 578 - apply WPS config changes to all interfaces that use WPS 579 - when an attack is detected on any interface, disable AP PIN on 580 all interfaces 581 * WPS ER: 582 - Add special AP Setup Locked mode to allow read only ER. 583 ap_setup_locked=2 can now be used to enable a special mode where 584 WPS ER can learn the current AP settings, but cannot change them. 585 - Show SetSelectedRegistrar events as ctrl_iface events 586 - Add wps_er_set_config to enroll a network based on a local 587 network configuration block instead of having to (re-)learn the 588 current AP settings with wps_er_learn. 589 - Allow AP filtering based on IP address, add ctrl_iface event for 590 learned AP settings, add wps_er_config command to configure an AP. 591 * WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2) 592 - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool 593 for testing protocol extensibility. 594 - Add build option CONFIG_WPS_STRICT to allow disabling of WPS 595 workarounds. 596 - Add support for AuthorizedMACs attribute. 597 * TDLS: 598 - Propogate TDLS related nl80211 capability flags from kernel and 599 add them as driver capability flags. If the driver doesn't support 600 capabilities, assume TDLS is supported internally. When TDLS is 601 explicitly not supported, disable all user facing TDLS operations. 602 - Allow TDLS to be disabled at runtime (mostly for testing). 603 Use set tdls_disabled. 604 - Honor AP TDLS settings that prohibit/allow TDLS. 605 - Add a special testing feature for changing TDLS behavior. Use 606 CONFIG_TDLS_TESTING build param to enable. Configure at runtime 607 with tdls_testing cli command. 608 - Add support for TDLS 802.11z. 609 * wlantest: Add a tool wlantest for IEEE802.11 protocol testing. 610 wlantest can be used to capture frames from a monitor interface 611 for realtime capturing or from pcap files for offline analysis. 612 * Interworking: Support added for 802.11u. Enable in .config with 613 CONFIG_INTERWORKING. See wpa_supplicant.conf for config parameters 614 for interworking. wpa_cli commands added to support this are 615 interworking_select, interworking_connect, anqp_get, fetch_anqp, 616 and stop_fetch_anqp. 617 * Android: Add build and runtime support for Android wpa_supplicant. 618 * bgscan learn: Add new bgscan that learns BSS information based on 619 previous scans, and uses that information to dynamically generate 620 the list of channels for background scans. 621 * Add a new debug message level for excessive information. Use 622 -ddd to enable. 623 * TLS: Add support for tls_disable_time_checks=1 in client mode. 624 * Internal TLS: 625 - Add support for TLS v1.1 (RFC 4346). Enable with build parameter 626 CONFIG_TLSV11. 627 - Add domainComponent parser for X.509 names. 628 * Linux: Add RFKill support by adding an interface state "disabled". 629 * Reorder some IEs to get closer to IEEE 802.11 standard. Move 630 WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames. 631 Move HT IEs to be later in (Re)Assoc Resp. 632 * Solaris: Add support for wired 802.1X client. 633 * Wi-Fi Direct support. See README-P2P for more information. 634 * Many bugfixes. 635 636 2010-04-18 - v0.7.2 637 * nl80211: fixed number of issues with roaming 638 * avoid unnecessary roaming if multiple APs with similar signal 639 strength are present in scan results 640 * add TLS client events and server probing to ease design of 641 automatic detection of EAP parameters 642 * add option for server certificate matching (SHA256 hash of the 643 certificate) instead of trusted CA certificate configuration 644 * bsd: Cleaned up driver wrapper and added various low-level 645 configuration options 646 * wpa_gui-qt4: do not show too frequent WPS AP available events as 647 tray messages 648 * TNC: fixed issues with fragmentation 649 * EAP-TNC: add Flags field into fragment acknowledgement (needed to 650 interoperate with other implementations; may potentially breaks 651 compatibility with older wpa_supplicant/hostapd versions) 652 * wpa_cli: added option for using a separate process to receive event 653 messages to reduce latency in showing these 654 (CFLAGS += -DCONFIG_WPA_CLI_FORK=y in .config to enable this) 655 * maximum BSS table size can now be configured (bss_max_count) 656 * BSSes to be included in the BSS table can be filtered based on 657 configured SSIDs to save memory (filter_ssids) 658 * fix number of issues with IEEE 802.11r/FT; this version is not 659 backwards compatible with old versions 660 * nl80211: add support for IEEE 802.11r/FT protocol (both over-the-air 661 and over-the-DS) 662 * add freq_list network configuration parameter to allow the AP 663 selection to filter out entries based on the operating channel 664 * add signal strength change events for bgscan; this allows more 665 dynamic changes to background scanning interval based on changes in 666 the signal strength with the current AP; this improves roaming within 667 ESS quite a bit, e.g., with bgscan="simple:30:-45:300" in the network 668 configuration block to request background scans less frequently when 669 signal strength remains good and to automatically trigger background 670 scans whenever signal strength drops noticeably 671 (this is currently only available with nl80211) 672 * add BSSID and reason code (if available) to disconnect event messages 673 * wpa_gui-qt4: more complete support for translating the GUI with 674 linguist and add German translation 675 * fix DH padding with internal crypto code (mainly, for WPS) 676 * do not trigger initial scan automatically anymore if there are no 677 enabled networks 678 679 2010-01-16 - v0.7.1 680 * cleaned up driver wrapper API (struct wpa_driver_ops); the new API 681 is not fully backwards compatible, so out-of-tree driver wrappers 682 will need modifications 683 * cleaned up various module interfaces 684 * merge hostapd and wpa_supplicant developers' documentation into a 685 single document 686 * nl80211: use explicit deauthentication to clear cfg80211 state to 687 avoid issues when roaming between APs 688 * dbus: major design changes in the new D-Bus API 689 (fi.w1.wpa_supplicant1) 690 * nl80211: added support for IBSS networks 691 * added internal debugging mechanism with backtrace support and memory 692 allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y) 693 * added WPS ER unsubscription command to more cleanly unregister from 694 receiving UPnP events when ER is terminated 695 * cleaned up AP mode operations to avoid need for virtual driver_ops 696 wrapper 697 * added BSS table to maintain more complete scan result information 698 over multiple scans (that may include only partial results) 699 * wpa_gui-qt4: update Peers dialog information more dynamically while 700 the dialog is kept open 701 * fixed PKCS#12 use with OpenSSL 1.0.0 702 * driver_wext: Added cfg80211-specific optimization to avoid some 703 unnecessary scans and to speed up association 704 705 2009-11-21 - v0.7.0 706 * increased wpa_cli ping interval to 5 seconds and made this 707 configurable with a new command line options (-G<seconds>) 708 * fixed scan buffer processing with WEXT to handle up to 65535 709 byte result buffer (previously, limited to 32768 bytes) 710 * allow multiple driver wrappers to be specified on command line 711 (e.g., -Dnl80211,wext); the first one that is able to initialize the 712 interface will be used 713 * added support for multiple SSIDs per scan request to optimize 714 scan_ssid=1 operations in ap_scan=1 mode (i.e., search for hidden 715 SSIDs); this requires driver support and can currently be used only 716 with nl80211 717 * added support for WPS USBA out-of-band mechanism with USB Flash 718 Drives (UFD) (CONFIG_WPS_UFD=y) 719 * driver_ndis: add PAE group address to the multicast address list to 720 fix wired IEEE 802.1X authentication 721 * fixed IEEE 802.11r key derivation function to match with the standard 722 (note: this breaks interoperability with previous version) [Bug 303] 723 * added better support for drivers that allow separate authentication 724 and association commands (e.g., mac80211-based Linux drivers with 725 nl80211; SME in wpa_supplicant); this allows over-the-air FT protocol 726 to be used (IEEE 802.11r) 727 * fixed SHA-256 based key derivation function to match with the 728 standard when using CCMP (for IEEE 802.11r and IEEE 802.11w) 729 (note: this breaks interoperability with previous version) [Bug 307] 730 * use shared driver wrapper files with hostapd 731 * added AP mode functionality (CONFIG_AP=y) with mode=2 in the network 732 block; this can be used for open and WPA2-Personal networks 733 (optionally, with WPS); this links in parts of hostapd functionality 734 into wpa_supplicant 735 * wpa_gui-qt4: added new Peers dialog to show information about peers 736 (other devices, including APs and stations, etc. in the neighborhood) 737 * added support for WPS External Registrar functionality (configure APs 738 and enroll new devices); can be used with wpa_gui-qt4 Peers dialog 739 and wpa_cli commands wps_er_start, wps_er_stop, wps_er_pin, 740 wps_er_pbc, wps_er_learn 741 (this can also be used with a new 'none' driver wrapper if no 742 wireless device or IEEE 802.1X on wired is needed) 743 * driver_nl80211: multiple updates to provide support for new Linux 744 nl80211/mac80211 functionality 745 * updated management frame protection to use IEEE Std 802.11w-2009 746 * fixed number of small WPS issues and added workarounds to 747 interoperate with common deployed broken implementations 748 * added support for NFC out-of-band mechanism with WPS 749 * driver_ndis: fixed wired IEEE 802.1X authentication with PAE group 750 address frames 751 * added preliminary support for IEEE 802.11r RIC processing 752 * added support for specifying subset of enabled frequencies to scan 753 (scan_freq option in the network configuration block); this can speed 754 up scanning process considerably if it is known that only a small 755 subset of channels is actually used in the network (this is currently 756 supported only with -Dnl80211) 757 * added a workaround for race condition between receiving the 758 association event and the following EAPOL-Key 759 * added background scan and roaming infrastructure to allow 760 network-specific optimizations to be used to improve roaming within 761 an ESS (same SSID) 762 * added new DBus interface (fi.w1.wpa_supplicant1) 763 764 2009-01-06 - v0.6.7 765 * added support for Wi-Fi Protected Setup (WPS) 766 (wpa_supplicant can now be configured to act as a WPS Enrollee to 767 enroll credentials for a network using PIN and PBC methods; in 768 addition, wpa_supplicant can act as a wireless WPS Registrar to 769 configure an AP); WPS support can be enabled by adding CONFIG_WPS=y 770 into .config and setting the runtime configuration variables in 771 wpa_supplicant.conf (see WPS section in the example configuration 772 file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to 773 manage WPS negotiation; see README-WPS for more details 774 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf) 775 * added support for using driver_test over UDP socket 776 * fixed PEAPv0 Cryptobinding interoperability issue with Windows Server 777 2008 NPS; optional cryptobinding is now enabled (again) by default 778 * fixed PSK editing in wpa_gui 779 * changed EAP-GPSK to use the IANA assigned EAP method type 51 780 * added a Windows installer that includes WinPcap and all the needed 781 DLLs; in addition, it set up the registry automatically so that user 782 will only need start wpa_gui to get prompted to start the wpasvc 783 servide and add a new interface if needed through wpa_gui dialog 784 * updated management frame protection to use IEEE 802.11w/D7.0 785 786 2008-11-23 - v0.6.6 787 * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA 788 (can be used to simulate test SIM/USIM card with a known private key; 789 enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config 790 and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration) 791 * added a new network configuration option, wpa_ptk_rekey, that can be 792 used to enforce frequent PTK rekeying, e.g., to mitigate some attacks 793 against TKIP deficiencies 794 * added an optional mitigation mechanism for certain attacks against 795 TKIP by delaying Michael MIC error reports by a random amount of time 796 between 0 and 60 seconds; this can be enabled with a build option 797 CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config 798 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits, 799 not bytes 800 * updated OpenSSL code for EAP-FAST to use an updated version of the 801 session ticket overriding API that was included into the upstream 802 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is 803 needed with that version anymore) 804 * updated userspace MLME instructions to match with the current Linux 805 mac80211 implementation; please also note that this can only be used 806 with driver_nl80211.c (the old code from driver_wext.c was removed) 807 * added support (Linux only) for RoboSwitch chipsets (often found in 808 consumer grade routers); driver interface 'roboswitch' 809 * fixed canceling of PMKSA caching when using drivers that generate 810 RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know 811 about 812 813 2008-11-01 - v0.6.5 814 * added support for SHA-256 as X.509 certificate digest when using the 815 internal X.509/TLSv1 implementation 816 * updated management frame protection to use IEEE 802.11w/D6.0 817 * added support for using SHA256-based stronger key derivation for WPA2 818 (IEEE 802.11w) 819 * fixed FT (IEEE 802.11r) authentication after a failed association to 820 use correct FTIE 821 * added support for configuring Phase 2 (inner/tunneled) authentication 822 method with wpa_gui-qt4 823 824 2008-08-10 - v0.6.4 825 * added support for EAP Sequences in EAP-FAST Phase 2 826 * added support for using TNC with EAP-FAST 827 * added driver_ps3 for the PS3 Linux wireless driver 828 * added support for optional cryptobinding with PEAPv0 829 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to 830 allow fallback to full handshake if server rejects PAC-Opaque 831 * added fragmentation support for EAP-TNC 832 * added support for parsing PKCS #8 formatted private keys into the 833 internal TLS implementation (both PKCS #1 RSA key and PKCS #8 834 encapsulated RSA key can now be used) 835 * added option of using faster, but larger, routines in the internal 836 LibTomMath (for internal TLS implementation) to speed up DH and RSA 837 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y) 838 * fixed race condition between disassociation event and group key 839 handshake to avoid getting stuck in incorrect state [Bug 261] 840 * fixed opportunistic key caching (proactive_key_caching) 841 842 2008-02-22 - v0.6.3 843 * removed 'nai' and 'eappsk' network configuration variables that were 844 previously used for configuring user identity and key for EAP-PSK, 845 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the 846 replacement for 'nai' (if old configuration used a separate 847 'identity' value, that would now be configured as 848 'anonymous_identity'). 'password' field is now used as the 849 replacement for 'eappsk' (it can also be set using hexstring to 850 present random binary data) 851 * removed '-w' command line parameter (wait for interface to be added, 852 if needed); cleaner way of handling this functionality is to use an 853 external mechanism (e.g., hotplug scripts) that start wpa_supplicant 854 when an interface is added 855 * updated FT support to use the latest draft, IEEE 802.11r/D9.0 856 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for 857 indicating when new scan results become available 858 * added new ctrl_iface command, BSS, to allow scan results to be 859 fetched without hitting the message size limits (this command 860 can be used to iterate through the scan results one BSS at the time) 861 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION 862 attributes in EAP-SIM Start/Response when using fast reauthentication 863 * fixed EAPOL not to end up in infinite loop when processing dynamic 864 WEP keys with IEEE 802.1X 865 * fixed problems in getting NDIS events from WMI on Windows 2000 866 867 2008-01-01 - v0.6.2 868 * added support for Makefile builds to include debug-log-to-a-file 869 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line) 870 * fixed EAP-SIM and EAP-AKA message parser to validate attribute 871 lengths properly to avoid potential crash caused by invalid messages 872 * added data structure for storing allocated buffers (struct wpabuf); 873 this does not affect wpa_supplicant usage, but many of the APIs 874 changed and various interfaces (e.g., EAP) is not compatible with old 875 versions 876 * added support for protecting EAP-AKA/Identity messages with 877 AT_CHECKCODE (optional feature in RFC 4187) 878 * added support for protected result indication with AT_RESULT_IND for 879 EAP-SIM and EAP-AKA (phase1="result_ind=1") 880 * added driver_wext workaround for race condition between scanning and 881 association with drivers that take very long time to scan all 882 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now 883 using a longer hardcoded timeout for the scan if the driver supports 884 notifications for scan completion (SIOCGIWSCAN event); this helps, 885 e.g., in cases where wpa_supplicant and madwifi driver ended up in 886 loop where the driver did not even try to associate 887 * stop EAPOL timer tick when no timers are in use in order to reduce 888 power consumption (no need to wake up the process once per second) 889 [Bug 237] 890 * added support for privilege separation (run only minimal part of 891 wpa_supplicant functionality as root and rest as unprivileged, 892 non-root process); see 'Privilege separation' in README for details; 893 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y 894 in .config 895 * changed scan results data structure to include all information 896 elements to make it easier to support new IEs; old get_scan_result() 897 driver_ops is still supported for backwards compatibility (results 898 are converted internally to the new format), but all drivers should 899 start using the new get_scan_results2() to make them more likely to 900 work with new features 901 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4 902 application, i.e., it does not require Qt3Support anymore; Windows 903 binary of wpa_gui.exe is now from this directory and only requires 904 QtCore4.dll and QtGui4.dll libraries 905 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs 906 available as a separate package to make wpa_gui installation easier: 907 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip 908 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt); 909 only shared key/password authentication is supported in this version 910 911 2007-11-24 - v0.6.1 912 * added support for configuring password as NtPasswordHash 913 (16-byte MD4 hash of password) in hash:<32 hex digits> format 914 * added support for fallback from abbreviated TLS handshake to 915 full handshake when using EAP-FAST (e.g., due to an expired 916 PAC-Opaque) 917 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 918 draft (draft-ietf-emu-eap-gpsk-07.txt) 919 * added support for drivers that take care of RSN 4-way handshake 920 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and 921 WPA_ALG_PMK in set_key) 922 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in 923 .config); this version supports only ap_scan=2 mode and allow the 924 driver to take care of the 4-way handshake 925 * fixed a buffer overflow in parsing TSF from scan results when using 926 driver_wext.c with a driver that includes the TSF (e.g., iwl4965) 927 [Bug 232] 928 * updated FT support to use the latest draft, IEEE 802.11r/D8.0 929 * fixed an integer overflow issue in the ASN.1 parser used by the 930 (experimental) internal TLS implementation to avoid a potential 931 buffer read overflow 932 * fixed a race condition with -W option (wait for a control interface 933 monitor before starting) that could have caused the first messages to 934 be lost 935 * added support for processing TNCC-TNCS-Messages to report 936 recommendation (allow/none/isolate) when using TNC [Bug 243] 937 938 2007-05-28 - v0.6.0 939 * added network configuration parameter 'frequency' for setting 940 initial channel for IBSS (adhoc) networks 941 * added experimental IEEE 802.11r/D6.0 support 942 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48 943 * updated EAP-PSK to use the IANA-allocated EAP type 47 944 * fixed EAP-PAX key derivation 945 * fixed EAP-PSK bit ordering of the Flags field 946 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in 947 tunnelled identity request (previously, the identifier from the outer 948 method was used, not the tunnelled identifier which could be 949 different) 950 * added support for fragmentation of outer TLS packets during Phase 2 951 of EAP-PEAP/TTLS/FAST 952 * fixed EAP-TTLS AVP parser processing for too short AVP lengths 953 * added support for EAP-FAST authentication with inner methods that 954 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported 955 for PAC provisioning) 956 * added support for authenticated EAP-FAST provisioning 957 * added support for configuring maximum number of EAP-FAST PACs to 958 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string) 959 * added support for storing EAP-FAST PACs in binary format 960 (fast_pac_format=binary in phase1 string) 961 * fixed dbus ctrl_iface to validate message interface before 962 dispatching to avoid a possible segfault [Bug 190] 963 * fixed PeerKey key derivation to use the correct PRF label 964 * updated Windows binary build to link against OpenSSL 0.9.8d and 965 added support for EAP-FAST 966 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 967 draft (draft-ietf-emu-eap-gpsk-04.txt) 968 * fixed EAP-AKA Notification processing to allow Notification to be 969 processed after AKA Challenge response has been sent 970 * updated to use IEEE 802.11w/D2.0 for management frame protection 971 (still experimental) 972 * fixed EAP-TTLS implementation not to crash on use of freed memory 973 if TLS library initialization fails 974 * added support for EAP-TNC (Trusted Network Connect) 975 (this version implements the EAP-TNC method and EAP-TTLS changes 976 needed to run two methods in sequence (IF-T) and the IF-IMC and 977 IF-TNCCS interfaces from TNCC) 978 979 2006-11-24 - v0.5.6 980 * added experimental, integrated TLSv1 client implementation with the 981 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by 982 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in 983 .config); this can be useful, e.g., if the target system does not 984 have a suitable TLS library and a minimal code size is required 985 (total size of this internal TLS/crypto code is bit under 50 kB on 986 x86 and the crypto code is shared by rest of the supplicant so some 987 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB) 988 * removed STAKey handshake since PeerKey handshake has replaced it in 989 IEEE 802.11ma and there are no known deployments of STAKey 990 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 991 draft (draft-ietf-emu-eap-gpsk-01.txt) 992 * added preliminary implementation of IEEE 802.11w/D1.0 (management 993 frame protection) 994 (Note: this requires driver support to work properly.) 995 (Note2: IEEE 802.11w is an unapproved draft and subject to change.) 996 * fixed Windows named pipes ctrl_iface to not stop listening for 997 commands if client program opens a named pipe and closes it 998 immediately without sending a command 999 * fixed USIM PIN status determination for the case that PIN is not 1000 needed (this allows EAP-AKA to be used with USIM cards that do not 1001 use PIN) 1002 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to 1003 be used with cards that do not support file selection based on 1004 partial AID 1005 * added support for matching the subjectAltName of the authentication 1006 server certificate against multiple name components (e.g., 1007 altsubject_match="DNS:server.example.com;DNS:server2.example.com") 1008 * fixed EAP-SIM/AKA key derivation for re-authentication case (only 1009 affects IEEE 802.1X with dynamic WEP keys) 1010 * changed ctrl_iface network configuration 'get' operations to not 1011 return password/key material; if these fields are requested, "*" 1012 will be returned if the password/key is set, but the value of the 1013 parameter is not exposed 1014 1015 2006-08-27 - v0.5.5 1016 * added support for building Windows version with UNICODE defined 1017 (wide-char functions) 1018 * driver_ndis: fixed static WEP configuration to avoid race condition 1019 issues with some NDIS drivers between association and setting WEP 1020 keys 1021 * driver_ndis: added validation for IELength value in scan results to 1022 avoid crashes when using buggy NDIS drivers [Bug 165] 1023 * fixed Release|Win32 target in the Visual Studio project files 1024 (previously, only Debug|Win32 target was set properly) 1025 * changed control interface API call wpa_ctrl_pending() to allow it to 1026 return -1 on error (e.g., connection lost); control interface clients 1027 will need to make sure that they verify that the value is indeed >0 1028 when determining whether there are pending messages 1029 * added an alternative control interface backend for Windows targets: 1030 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default 1031 control interface mechanism for Windows builds (previously, UDP to 1032 localhost was used) 1033 * changed ctrl_interface configuration for UNIX domain sockets: 1034 - deprecated ctrl_interface_group variable (it may be removed in 1035 future versions) 1036 - allow both directory and group be configured with ctrl_interface 1037 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel 1038 - ctrl_interface=/var/run/wpa_supplicant is still supported for the 1039 case when group is not changed 1040 * added support for controlling more than one interface per process in 1041 Windows version 1042 * added a workaround for a case where the AP is using unknown address 1043 (e.g., MAC address of the wired interface) as the source address for 1044 EAPOL-Key frames; previously, that source address was used as the 1045 destination for EAPOL-Key frames and in key derivation; now, BSSID is 1046 used even if the source address does not match with it 1047 (this resolves an interoperability issue with Thomson SpeedTouch 580) 1048 * added a workaround for UDP-based control interface (which was used in 1049 Windows builds before this release) to prevent packets with forged 1050 addresses from being accepted as local control requests 1051 * removed ndis_events.cpp and possibility of using external 1052 ndis_events.exe; C version (ndis_events.c) is fully functional and 1053 there is no desire to maintain two separate versions of this 1054 implementation 1055 * ndis_events: Changed NDIS event notification design to use WMI to 1056 learn the adapter description through Win32_PnPEntity class; this 1057 should fix some cases where the adapter name was not recognized 1058 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500 1059 USB) [Bug 113] 1060 * fixed selection of the first network in ap_scan=2 mode; previously, 1061 wpa_supplicant could get stuck in SCANNING state when only the first 1062 network for enabled (e.g., after 'wpa_cli select_network 0') 1063 * winsvc: added support for configuring ctrl_interface parameters in 1064 registry (ctrl_interface string value in 1065 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is 1066 required to enable control interface (previously, this was hardcoded 1067 to be enabled) 1068 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4 1069 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format 1070 1071 2006-06-20 - v0.5.4 1072 * fixed build with CONFIG_STAKEY=y [Bug 143] 1073 * added support for doing MLME (IEEE 802.11 management frame 1074 processing) in wpa_supplicant when using Devicescape IEEE 802.11 1075 stack (wireless-dev.git tree) 1076 * added a new network block configuration option, fragment_size, to 1077 configure the maximum EAP fragment size 1078 * driver_ndis: Disable WZC automatically for the selected interface to 1079 avoid conflicts with two programs trying to control the radio; WZC 1080 will be re-enabled (if it was enabled originally) when wpa_supplicant 1081 is terminated 1082 * added an experimental TLSv1 client implementation 1083 (CONFIG_TLS=internal) that can be used instead of an external TLS 1084 library, e.g., to reduce total size requirement on systems that do 1085 not include any TLS library by default (this is not yet complete; 1086 basic functionality is there, but certificate validation is not yet 1087 included) 1088 * added PeerKey handshake implementation for IEEE 802.11e 1089 direct link setup (DLS) to replace STAKey handshake 1090 * fixed WPA PSK update through ctrl_iface for the case where the old 1091 PSK was derived from an ASCII passphrase and the new PSK is set as 1092 a raw PSK (hex string) 1093 * added new configuration option for identifying which network block 1094 was used (id_str in wpa_supplicant.conf; included on 1095 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental 1096 variable in wpa_cli action scripts; in addition WPA_ID variable is 1097 set to the current unique identifier that wpa_supplicant assigned 1098 automatically for the network and that can be used with 1099 GET_NETWORK/SET_NETWORK ctrl_iface commands) 1100 * wpa_cli action script is now called only when the connect/disconnect 1101 status changes or when associating with a different network 1102 * fixed configuration parser not to remove CCMP from group cipher list 1103 if WPA-None (adhoc) is used (pairwise=NONE in that case) 1104 * fixed integrated NDIS events processing not to hang the process due 1105 to a missed change in eloop_win.c API in v0.5.3 [Bug 155] 1106 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK, 1107 draft-clancy-emu-eap-shared-secret-00.txt) 1108 * added Microsoft Visual Studio 2005 solution and project files for 1109 build wpa_supplicant for Windows (see vs2005 subdirectory) 1110 * eloop_win: fixed unregistration of Windows events 1111 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet 1112 at the end of RSN pre-authentication and added unregistration of 1113 a Windows event to avoid getting eloop_win stuck with an invalid 1114 handle 1115 * driver_ndis: added support for selecting AP based on BSSID 1116 * added new environmental variable for wpa_cli action scripts: 1117 WPA_CTRL_DIR is the current control interface directory 1118 * driver_ndis: added support for using NDISUIO instead of WinPcap for 1119 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new 1120 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build 1121 wpa_supplicant without requiring WinPcap; note that using NDISUIO 1122 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows 1123 only one application to open the device 1124 * changed NDIS driver naming to only include device GUID, e.g., 1125 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap 1126 specific \Device\NPF_ prefix before the GUID; the prefix is still 1127 allowed for backwards compatibility, but it is not required anymore 1128 when specifying the interface 1129 * driver_ndis: re-initialize driver interface is the adapter is removed 1130 and re-inserted [Bug 159] 1131 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on 1132 big endian hosts [Bug 146] 1133 1134 2006-04-27 - v0.5.3 1135 * fixed EAP-GTC response to include correct user identity when run as 1136 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2) 1137 * driver_ndis: Fixed encryption mode configuration for unencrypted 1138 networks (some NDIS drivers ignored this, but others, e.g., Broadcom, 1139 refused to associate with open networks) [Bug 106] 1140 * driver_ndis: use BSSID OID polling to detect when IBSS network is 1141 formed even when ndis_events code is included since some NDIS drivers 1142 do not generate media connect events in IBSS mode 1143 * config_winreg: allow global ctrl_interface parameter to be configured 1144 in Windows registry 1145 * config_winreg: added support for saving configuration data into 1146 Windows registry 1147 * added support for controlling network device operational state 1148 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see 1149 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client 1150 that can use this information) 1151 * driver_wext: added support for WE-21 change to SSID configuration 1152 * driver_wext: fixed privacy configuration for static WEP keys mode 1153 [Bug 140] 1154 * added an optional driver_ops callback for MLME-SETPROTECTION.request 1155 primitive 1156 * added support for EAP-SAKE (no EAP method number allocated yet, so 1157 this is using the same experimental type 255 as EAP-PSK) 1158 * added support for dynamically loading EAP methods (.so files) instead 1159 of requiring them to be statically linked in; this is disabled by 1160 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information 1161 on how to use this) 1162 1163 2006-03-19 - v0.5.2 1164 * do not try to use USIM APDUs when initializing PC/SC for SIM card 1165 access for a network that has not enabled EAP-AKA 1166 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in 1167 v0.5.1 due to the new support for expanded EAP types) 1168 * added support for generating EAP Expanded Nak 1169 * try to fetch scan results once before requesting new scan when 1170 starting up in ap_scan=1 mode (this can speed up initial association 1171 a lot with, e.g., madwifi-ng driver) 1172 * added support for receiving EAPOL frames from a Linux bridge 1173 interface (-bbr0 on command line) 1174 * fixed EAPOL re-authentication for sessions that used PMKSA caching 1175 * changed EAP method registration to use a dynamic list of methods 1176 instead of a static list generated at build time 1177 * fixed PMKSA cache deinitialization not to use freed memory when 1178 removing PMKSA entries 1179 * fixed a memory leak in EAP-TTLS re-authentication 1180 * reject WPA/WPA2 message 3/4 if it does not include any valid 1181 WPA/RSN IE 1182 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg 1183 if the driver does not support SIOCSIWAUTH 1184 1185 2006-01-29 - v0.5.1 1186 * driver_test: added better support for multiple APs and STAs by using 1187 a directory with sockets that include MAC address for each device in 1188 the name (driver_param=test_dir=/tmp/test) 1189 * added support for EAP expanded type (vendor specific EAP methods) 1190 * added AP_SCAN command into ctrl_iface so that ap_scan configuration 1191 option can be changed if needed 1192 * wpa_cli/wpa_gui: skip non-socket files in control directory when 1193 using UNIX domain sockets; this avoids selecting an incorrect 1194 interface (e.g., a PID file could be in this directory, even though 1195 use of this directory for something else than socket files is not 1196 recommended) 1197 * fixed TLS library deinitialization after RSN pre-authentication not 1198 to disable TLS library for normal authentication 1199 * driver_wext: Remove null-termination from SSID length if the driver 1200 used it; some Linux drivers do this and they were causing problems in 1201 wpa_supplicant not finding matching configuration block. This change 1202 would break a case where the SSID actually ends in '\0', but that is 1203 not likely to happen in real use. 1204 * fixed PMKSA cache processing not to trigger deauthentication if the 1205 current PMKSA cache entry is replaced with a valid new entry 1206 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes 1207 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or 1208 ap_scan=2) 1209 1210 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases) 1211 * added experimental STAKey handshake implementation for IEEE 802.11e 1212 direct link setup (DLS); note: this is disabled by default in both 1213 build and runtime configuration (can be enabled with CONFIG_STAKEY=y 1214 and stakey=1) 1215 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to 1216 decrypt AT_ENCR_DATA attributes correctly 1217 * fixed EAP-AKA to allow resynchronization within the same session 1218 * made code closer to ANSI C89 standard to make it easier to port to 1219 other C libraries and compilers 1220 * started moving operating system or C library specific functions into 1221 wrapper functions defined in os.h and implemented in os_*.c to make 1222 code more portable 1223 * wpa_supplicant can now be built with Microsoft Visual C++ 1224 (e.g., with the freely available Toolkit 2003 version or Visual 1225 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an 1226 example makefile for nmake 1227 * added support for using Windows registry for command line parameters 1228 (CONFIG_MAIN=main_winsvc) and configuration data 1229 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry 1230 contents; this version can be run both as a Windows service and as a 1231 normal application; 'wpasvc.exe app' to start as applicant, 1232 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service, 1233 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to 1234 unregister a service 1235 * made it possible to link ndis_events.exe functionality into 1236 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED 1237 * added better support for multiple control interface backends 1238 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported 1239 * fixed PC/SC code to use correct length for GSM AUTH command buffer 1240 and to not use pioRecvPci with SCardTransmit() calls; these were not 1241 causing visible problems with pcsc-lite, but Windows Winscard.dll 1242 refused the previously used parameters; this fixes EAP-SIM and 1243 EAP-AKA authentication using SIM/USIM card under Windows 1244 * added new event loop implementation for Windows using 1245 WaitForMultipleObject() instead of select() in order to allow waiting 1246 for non-socket objects; this can be selected with 1247 CONFIG_ELOOP=eloop_win in .config 1248 * added support for selecting l2_packet implementation in .config 1249 (CONFIG_L2_PACKET; following options are available now: linux, pcap, 1250 winpcap, freebsd, none) 1251 * added new l2_packet implementation for WinPcap 1252 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to 1253 reduce latency in EAPOL receive processing from about 100 ms to about 1254 3 ms 1255 * added support for EAP-FAST key derivation using other ciphers than 1256 RC4-128-SHA for authentication and AES128-SHA for provisioning 1257 * added support for configuring CA certificate as DER file and as a 1258 configuration blob 1259 * fixed private key configuration as configuration blob and added 1260 support for using PKCS#12 as a blob 1261 * tls_gnutls: added support for using PKCS#12 files; added support for 1262 session resumption 1263 * added support for loading trusted CA certificates from Windows 1264 certificate store: ca_cert="cert_store://<name>", where <name> is 1265 likely CA (Intermediate CA certificates) or ROOT (root certificates) 1266 * added C version of ndis_events.cpp and made it possible to build this 1267 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more 1268 easily on cross-compilation builds 1269 * added wpasvc.exe into Windows binary release; this is an alternative 1270 version of wpa_supplicant.exe with configuration backend using 1271 Windows registry and with the entry point designed to run as a 1272 Windows service 1273 * integrated ndis_events.exe functionality into wpa_supplicant.exe and 1274 wpasvc.exe and removed this additional tool from the Windows binary 1275 release since it is not needed anymore 1276 * load winscard.dll functions dynamically when building with MinGW 1277 since MinGW does not yet include winscard library 1278 1279 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases) 1280 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap 1281 and WinPcap to receive frames sent to PAE group address 1282 * disable EAP state machine when IEEE 802.1X authentication is not used 1283 in order to get rid of bogus "EAP failed" messages 1284 * fixed OpenSSL error reporting to go through all pending errors to 1285 avoid confusing reports of old errors being reported at later point 1286 during handshake 1287 * fixed configuration file updating to not write empty variables 1288 (e.g., proto or key_mgmt) that the file parser would not accept 1289 * fixed ADD_NETWORK ctrl_iface command to use the same default values 1290 for variables as empty network definitions read from config file 1291 would get 1292 * fixed EAP state machine to not discard EAP-Failure messages in many 1293 cases (e.g., during TLS handshake) 1294 * fixed a infinite loop in private key reading if the configured file 1295 cannot be parsed successfully 1296 * driver_madwifi: added support for madwifi-ng 1297 * wpa_gui: do not display password/PSK field contents 1298 * wpa_gui: added CA certificate configuration 1299 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID 1300 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if 1301 the new AP is using different WPA/RSN IE 1302 * use longer timeout for IEEE 802.11 association to avoid problems with 1303 drivers that may take more than five second to associate 1304 1305 2005-10-27 - v0.4.6 1306 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in 1307 RSN IE, but WPA IE would match with wpa_supplicant configuration 1308 * added support for named configuration blobs in order to avoid having 1309 to use file system for external files (e.g., certificates); 1310 variables can be set to "blob://<blob name>" instead of file path to 1311 use a named blob; supported fields: pac_file, client_cert, 1312 private_key 1313 * fixed RSN pre-authentication (it was broken in the clean up of WPA 1314 state machine interface in v0.4.5) 1315 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make 1316 sure the driver configures broadcast decryption correctly 1317 * added ca_path (and ca_path2) configuration variables that can be used 1318 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the 1319 system-wide trusted CA list 1320 * added support for starting wpa_supplicant without a configuration 1321 file (-C argument must be used to set ctrl_interface parameter for 1322 this case; in addition, -p argument can be used to provide 1323 driver_param; these new arguments can also be used with a 1324 configuration to override the values from the configuration) 1325 * added global control interface that can be optionally used for adding 1326 and removing network interfaces dynamically (-g command line argument 1327 for both wpa_supplicant and wpa_cli) without having to restart 1328 wpa_supplicant process 1329 * wpa_gui: 1330 - try to save configuration whenever something is modified 1331 - added WEP key configuration 1332 - added possibility to edit the current network configuration 1333 * driver_ndis: fixed driver polling not to increase frequency on each 1334 received EAPOL frame due to incorrectly cancelled timeout 1335 * added simple configuration file examples (in examples subdirectory) 1336 * fixed driver_wext.c to filter wireless events based on ifindex to 1337 avoid interfaces receiving events from other interfaces 1338 * delay sending initial EAPOL-Start couple of seconds to speed up 1339 authentication for the most common case of Authenticator starting 1340 EAP authentication immediately after association 1341 1342 2005-09-25 - v0.4.5 1343 * added a workaround for clearing keys with ndiswrapper to allow 1344 roaming from WPA enabled AP to plaintext one 1345 * added docbook documentation (doc/docbook) that can be used to 1346 generate, e.g., man pages 1347 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for 1348 PF_PACKET in order to prepare for network devices that do not use 1349 Ethernet headers (e.g., network stack with native IEEE 802.11 frames) 1350 * use receipt of EAPOL-Key frame as a lower layer success indication 1351 for EAP state machine to allow recovery from dropped EAP-Success 1352 frame 1353 * cleaned up internal EAPOL frame processing by not including link 1354 layer (Ethernet) header during WPA and EAPOL/EAP processing; this 1355 header is added only when transmitted the frame; this makes it easier 1356 to use wpa_supplicant on link layers that use different header than 1357 Ethernet 1358 * updated EAP-PSK to use draft 9 by default since this can now be 1359 tested with hostapd; removed support for draft 3, including 1360 server_nai configuration option from network blocks 1361 * driver_wired: add PAE address to the multicast address list in order 1362 to be able to receive EAPOL frames with drivers that do not include 1363 these multicast addresses by default 1364 * driver_wext: add support for WE-19 1365 * added support for multiple configuration backends (CONFIG_BACKEND 1366 option); currently, only 'file' is supported (i.e., the format used 1367 in wpa_supplicant.conf) 1368 * added support for updating configuration ('wpa_cli save_config'); 1369 this is disabled by default and can be enabled with global 1370 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli 1371 and wpa_gui to store the configuration changes in a permanent store 1372 * added GET_NETWORK ctrl_iface command 1373 (e.g., 'wpa_cli get_network 0 ssid') 1374 1375 2005-08-21 - v0.4.4 1376 * replaced OpenSSL patch for EAP-FAST support 1377 (openssl-tls-extensions.patch) with a more generic and correct 1378 patch (the new patch is not compatible with the previous one, so the 1379 OpenSSL library will need to be patched with the new patch in order 1380 to be able to build wpa_supplicant with EAP-FAST support) 1381 * added support for using Windows certificate store (through CryptoAPI) 1382 for client certificate and private key operations (EAP-TLS) 1383 (see wpa_supplicant.conf for more information on how to configure 1384 this with private_key) 1385 * ported wpa_gui to Windows 1386 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be 1387 built with the open source version of the Qt4 for Windows 1388 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used 1389 with drivers that do not support WPA 1390 * ndis_events: fixed Windows 2000 support 1391 * added support for enabling/disabling networks from the list of all 1392 configured networks ('wpa_cli enable_network <network id>' and 1393 'wpa_cli disable_network <network id>') 1394 * added support for adding and removing network from the current 1395 configuration ('wpa_cli add_network' and 'wpa_cli remove_network 1396 <network id>'); added networks are disabled by default and they can 1397 be enabled with enable_network command once the configuration is done 1398 for the new network; note: configuration file is not yet updated, so 1399 these new networks are lost when wpa_supplicant is restarted 1400 * added support for setting network configuration parameters through 1401 the control interface, for example: 1402 wpa_cli set_network 0 ssid "\"my network\"" 1403 * fixed parsing of strings that include both " and # within double 1404 quoted area (e.g., "start"#end") 1405 * added EAP workaround for PEAP session resumption: allow outer, 1406 i.e., not tunneled, EAP-Success to terminate session since; this can 1407 be disabled with eap_workaround=0 1408 (this was allowed for PEAPv1 before, but now it is also allowed for 1409 PEAPv0 since at least one RADIUS authentication server seems to be 1410 doing this for PEAPv0, too) 1411 * wpa_gui: added preliminary support for adding new networks to the 1412 wpa_supplicant configuration (double click on the scan results to 1413 open network configuration) 1414 1415 2005-06-26 - v0.4.3 1416 * removed interface for external EAPOL/EAP supplicant (e.g., 1417 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required 1418 anymore and is unlikely to be used by anyone 1419 * driver_ndis: fixed WinPcap 3.0 support 1420 * fixed build with CONFIG_DNET_PCAP=y on Linux 1421 * l2_packet: moved different implementations into separate files 1422 (l2_packet_*.c) 1423 1424 2005-06-12 - v0.4.2 1425 * driver_ipw: updated driver structures to match with ipw2200-1.0.4 1426 (note: ipw2100-1.1.0 is likely to require an update to work with 1427 this) 1428 * added support for using ap_scan=2 mode with multiple network blocks; 1429 wpa_supplicant will go through the networks one by one until the 1430 driver reports a successful association; this uses the same order for 1431 networks as scan_ssid=1 scans, i.e., the priority field is ignored 1432 and the network block order in the file is used instead 1433 * fixed a potential issue in RSN pre-authentication ending up using 1434 freed memory if pre-authentication times out 1435 * added support for matching alternative subject name extensions of the 1436 authentication server certificate; new configuration variables 1437 altsubject_match and altsubject_match2 1438 * driver_ndis: added support for IEEE 802.1X authentication with wired 1439 NDIS drivers 1440 * added support for querying private key password (EAP-TLS) through the 1441 control interface (wpa_cli/wpa_gui) if one is not included in the 1442 configuration file 1443 * driver_broadcom: fixed couple of memory leaks in scan result 1444 processing 1445 * EAP-PAX is now registered as EAP type 46 1446 * fixed EAP-PAX MAC calculation 1447 * fixed EAP-PAX CK and ICK key derivation 1448 * added support for using password with EAP-PAX (as an alternative to 1449 entering key with eappsk); SHA-1 hash of the password will be used as 1450 the key in this case 1451 * added support for arbitrary driver interface parameters through the 1452 configuration file with a new driver_param field; this adds a new 1453 driver_ops function set_param() 1454 * added possibility to override l2_packet module with driver interface 1455 API (new send_eapol handler); this can be used to implement driver 1456 specific TX/RX functions for EAPOL frames 1457 * fixed ctrl_interface_group processing for the case where gid is 1458 entered as a number, not group name 1459 * driver_test: added support for testing hostapd with wpa_supplicant 1460 by using test driver interface without any kernel drivers or network 1461 cards 1462 1463 2005-05-22 - v0.4.1 1464 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL 1465 packets to be encrypted; this was apparently broken by the changed 1466 ioctl order in v0.4.0 1467 * driver_madwifi: added preliminary support for compiling against 'BSD' 1468 branch of madwifi CVS tree 1469 * added support for EAP-MSCHAPv2 password retries within the same EAP 1470 authentication session 1471 * added support for password changes with EAP-MSCHAPv2 (used when the 1472 password has expired) 1473 * added support for reading additional certificates from PKCS#12 files 1474 and adding them to the certificate chain 1475 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys 1476 were used 1477 * fixed a possible double free in EAP-TTLS fast-reauthentication when 1478 identity or password is entered through control interface 1479 * display EAP Notification messages to user through control interface 1480 with "CTRL-EVENT-EAP-NOTIFICATION" prefix 1481 * added GUI version of wpa_cli, wpa_gui; this is not build 1482 automatically with 'make'; use 'make wpa_gui' to build (this requires 1483 Qt development tools) 1484 * added 'disconnect' command to control interface for setting 1485 wpa_supplicant in state where it will not associate before 1486 'reassociate' command has been used 1487 * added support for selecting a network from the list of all configured 1488 networks ('wpa_cli select_network <network id>'; this disabled all 1489 other networks; to re-enable, 'wpa_cli select_network any') 1490 * added support for getting scan results through control interface 1491 * added EAP workaround for PEAPv1 session resumption: allow outer, 1492 i.e., not tunneled, EAP-Success to terminate session since; this can 1493 be disabled with eap_workaround=0 1494 1495 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases) 1496 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be 1497 used to reduce the size of the wpa_supplicant considerably if 1498 debugging code is not needed 1499 * fixed EAPOL-Key validation to drop packets with invalid Key Data 1500 Length; such frames could have crashed wpa_supplicant due to buffer 1501 overflow 1502 * added support for wired authentication (IEEE 802.1X on wired 1503 Ethernet); driver interface 'wired' 1504 * obsoleted set_wpa() handler in the driver interface API (it can be 1505 replaced by moving enable/disable functionality into init()/deinit()) 1506 (calls to set_wpa() are still present for backwards compatibility, 1507 but they may be removed in the future) 1508 * driver_madwifi: fixed association in plaintext mode 1509 * modified the EAP workaround that accepts EAP-Success with incorrect 1510 Identifier to be even less strict about verification in order to 1511 interoperate with some authentication servers 1512 * added support for sending TLS alerts 1513 * added support for 'any' SSID wildcard; if ssid is not configured or 1514 is set to an empty string, any SSID will be accepted for non-WPA AP 1515 * added support for asking PIN (for SIM) from frontends (e.g., 1516 wpa_cli); if a PIN is needed, but not included in the configuration 1517 file, a control interface request is sent and EAP processing is 1518 delayed until the PIN is available 1519 * added support for using external devices (e.g., a smartcard) for 1520 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config); 1521 new wpa_supplicant.conf variables: 1522 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path 1523 - network: engine, engine_id, key_id 1524 * added experimental support for EAP-PAX 1525 * added monitor mode for wpa_cli (-a<path to a program to run>) that 1526 allows external commands (e.g., shell scripts) to be run based on 1527 wpa_supplicant events, e.g., when authentication has been completed 1528 and data connection is ready; other related wpa_cli arguments: 1529 -B (run in background), -P (write PID file); wpa_supplicant has a new 1530 command line argument (-W) that can be used to make it wait until a 1531 control interface command is received in order to avoid missing 1532 events 1533 * added support for opportunistic WPA2 PMKSA key caching (disabled by 1534 default, can be enabled with proactive_key_caching=1) 1535 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where 1536 Authenticator rejects PMKSA caching attempt and the driver is not 1537 using assoc_info events 1538 * added -P<pid file> argument for wpa_supplicant to write the current 1539 process id into a file 1540 1541 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases) 1542 * added new phase1 option parameter, include_tls_length=1, to force 1543 wpa_supplicant to add TLS Message Length field to all TLS messages 1544 even if the packet is not fragmented; this may be needed with some 1545 authentication servers 1546 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when 1547 using drivers that take care of AP selection (e.g., when using 1548 ap_scan=2) 1549 * fixed reprocessing of pending request after ctrl_iface requests for 1550 identity/password/otp 1551 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of 1552 EAP-PEAP and EAP-TTLS 1553 * all drivers using driver_wext: set interface up and select Managed 1554 mode when starting wpa_supplicant; set interface down when exiting 1555 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both 1556 ipw2100 and ipw2200; please note that this also changed the 1557 configuration variable in .config to CONFIG_DRIVER_IPW 1558 1559 2005-01-24 - v0.3.6 1560 * fixed a busy loop introduced in v0.3.5 for scan result processing 1561 when no matching AP is found 1562 1563 2005-01-23 - v0.3.5 1564 * added a workaround for an interoperability issue with a Cisco AP 1565 when using WPA2-PSK 1566 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as 1567 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow 1568 retransmission of dropped frames) 1569 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version 1570 (e.g., segfault when processing EAPOL-Key frames) 1571 * fixed EAP workaround and fast reauthentication configuration for 1572 RSN pre-authentication; previously these were disabled and 1573 pre-authentication would fail if the used authentication server 1574 requires EAP workarounds 1575 * added support for blacklisting APs that fail or timeout 1576 authentication in ap_scan=1 mode so that all APs are tried in cases 1577 where the ones with strongest signal level are failing authentication 1578 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS 1579 authentication attempt 1580 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded 1581 in the previous authentication (previously, only Phase 1 success was 1582 verified) 1583 1584 2005-01-09 - v0.3.4 1585 * added preliminary support for IBSS (ad-hoc) mode configuration 1586 (mode=1 in network block); this included a new key_mgmt mode 1587 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no 1588 key management; see wpa_supplicant.conf for more details and an 1589 example on how to configure this (note: this is currently implemented 1590 only for driver_hostapd.c, but the changes should be trivial to add 1591 in associate() handler for other drivers, too (assuming the driver 1592 supports WPA-None) 1593 * added preliminary port for native Windows (i.e., no cygwin) using 1594 mingw 1595 1596 2005-01-02 - v0.3.3 1597 * added optional support for GNU Readline and History Libraries for 1598 wpa_cli (CONFIG_READLINE) 1599 * cleaned up EAP state machine <-> method interface and number of 1600 small problems with error case processing not terminating on 1601 EAP-Failure but waiting for timeout 1602 * added couple of workarounds for interoperability issues with a 1603 Cisco AP when using WPA2 1604 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt); 1605 Note: This requires a patch for openssl to add support for TLS 1606 extensions and number of workarounds for operations without 1607 certificates. Proof of concept type of experimental patch is 1608 included in openssl-tls-extensions.patch. 1609 1610 2004-12-19 - v0.3.2 1611 * fixed private key loading for cases where passphrase is not set 1612 * fixed Windows/cygwin L2 packet handler freeing; previous version 1613 could cause a segfault when RSN pre-authentication was completed 1614 * added support for PMKSA caching with drivers that generate RSN IEs 1615 (e.g., NDIS); currently, this is only implemented in driver_ndis.c, 1616 but similar code can be easily added to driver_ndiswrapper.c once 1617 ndiswrapper gets full support for RSN PMKSA caching 1618 * improved recovery from PMKID mismatches by requesting full EAP 1619 authentication in case of failed PMKSA caching attempt 1620 * driver_ndis: added support for NDIS NdisMIncidateStatus() events 1621 (this requires that ndis_events is ran while wpa_supplicant is 1622 running) 1623 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys 1624 * added support for driver interfaces to replace the interface name 1625 based on driver/OS specific mapping, e.g., in case of driver_ndis, 1626 this allows the beginning of the adapter description to be used as 1627 the interface name 1628 * added support for CR+LF (Windows-style) line ends in configuration 1629 file 1630 * driver_ndis: enable radio before starting scanning, disable radio 1631 when exiting 1632 * modified association event handler to set portEnabled = FALSE before 1633 clearing port Valid in order to reset EAP state machine and avoid 1634 problems with new authentication getting ignored because of state 1635 machines ending up in AUTHENTICATED/SUCCESS state based on old 1636 information 1637 * added support for driver events to add PMKID candidates in order to 1638 allow drivers to give priority to most likely roaming candidates 1639 * driver_hostap: moved PrivacyInvoked configuration to associate() 1640 function so that this will not be set for plaintext connections 1641 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver 1642 interface can distinguish plaintext and IEEE 802.1X (no WPA) 1643 authentication 1644 * fixed static WEP key configuration to use broadcast/default type for 1645 all keys (previously, the default TX key was configured as pairwise/ 1646 unicast key) 1647 * driver_ndis: added legacy WPA capability detection for non-WPA2 1648 drivers 1649 * added support for setting static WEP keys for IEEE 802.1X without 1650 dynamic WEP keying (eapol_flags=0) 1651 1652 2004-12-12 - v0.3.1 1653 * added support for reading PKCS#12 (PFX) files (as a replacement for 1654 PEM/DER) to get certificate and private key (CONFIG_PKCS12) 1655 * fixed compilation with CONFIG_PCSC=y 1656 * added new ap_scan mode, ap_scan=2, for drivers that take care of 1657 association, but need to be configured with security policy and SSID, 1658 e.g., ndiswrapper and NDIS driver; this mode should allow such 1659 drivers to work with hidden SSIDs and optimized roaming; when 1660 ap_scan=2 is used, only the first network block in the configuration 1661 file is used and this configuration should have explicit security 1662 policy (i.e., only one option in the lists) for key_mgmt, pairwise, 1663 group, proto variables 1664 * added experimental port of wpa_supplicant for Windows 1665 - driver_ndis.c driver interface (NDIS OIDs) 1666 - currently, this requires cygwin and WinPcap 1667 - small utility, win_if_list, can be used to get interface name 1668 * control interface can now be removed at build time; add 1669 CONFIG_CTRL_IFACE=y to .config to maintain old functionality 1670 * optional Xsupplicant interface can now be removed at build time; 1671 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back) 1672 * added auth_alg to driver interface associate() parameters to make it 1673 easier for drivers to configure authentication algorithm as part of 1674 the association 1675 1676 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases) 1677 * driver_broadcom: added new driver interface for Broadcom wl.o driver 1678 (a generic driver for Broadcom IEEE 802.11a/g cards) 1679 * wpa_cli: fixed parsing of -p <path> command line argument 1680 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS 1681 ACK, not tunneled EAP-Success (of which only the first byte was 1682 actually send due to a bug in previous code); this seems to 1683 interoperate with most RADIUS servers that implements PEAPv1 1684 * PEAPv1: added support for terminating PEAP authentication on tunneled 1685 EAP-Success message; this can be configured by adding 1686 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf 1687 (some RADIUS servers require this whereas others require a tunneled 1688 reply 1689 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to 1690 the old label for key derivation; previously, the default was 1, 1691 but it looks like most existing PEAPv1 implementations use the old 1692 label which is thus more suitable default option 1693 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt) 1694 * fixed parsing of wep_tx_keyidx 1695 * added support for configuring list of allowed Phase 2 EAP types 1696 (for both EAP-PEAP and EAP-TTLS) instead of only one type 1697 * added support for configuring IEEE 802.11 authentication algorithm 1698 (auth_alg; mainly for using Shared Key authentication with static 1699 WEP keys) 1700 * added support for EAP-AKA (with UMTS SIM) 1701 * fixed couple of errors in PCSC handling that could have caused 1702 random-looking errors for EAP-SIM 1703 * added support for EAP-SIM pseudonyms and fast re-authentication 1704 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS 1705 session resumption) 1706 * added support for EAP-SIM with two challanges 1707 (phase1="sim_min_num_chal=3" can be used to require three challenges) 1708 * added support for configuring DH/DSA parameters for an ephemeral DH 1709 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters 1710 dh_file and dh_file2 (phase 2); this adds support for using DSA keys 1711 and optional DH key exchange to achieve forward secracy with RSA keys 1712 * added support for matching subject of the authentication server 1713 certificate with a substring when using EAP-TLS/PEAP/TTLS; new 1714 configuration variables subject_match and subject_match2 1715 * changed SSID configuration in driver_wext.c (used by many driver 1716 interfaces) to use ssid_len+1 as the length for SSID since some Linux 1717 drivers expect this 1718 * fixed couple of unaligned reads in scan result parsing to fix WPA 1719 connection on some platforms (e.g., ARM) 1720 * added driver interface for Intel ipw2100 driver 1721 * added support for LEAP with WPA 1722 * added support for larger scan results report (old limit was 4 kB of 1723 data, i.e., about 35 or so APs) when using Linux wireless extensions 1724 v17 or newer 1725 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start 1726 only if there is a PMKSA cache entry for the current AP 1727 * fixed error handling for case where reading of scan results fails: 1728 must schedule a new scan or wpa_supplicant will remain waiting 1729 forever 1730 * changed debug output to remove shared password/key material by 1731 default; all key information can be included with -K command line 1732 argument to match the previous behavior 1733 * added support for timestamping debug log messages (disabled by 1734 default, can be enabled with -t command line argument) 1735 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104 1736 if keys are not configured to be used; this fixes IEEE 802.1X mode 1737 with drivers that use this information to configure whether Privacy 1738 bit can be in Beacon frames (e.g., ndiswrapper) 1739 * avoid clearing driver keys if no keys have been configured since last 1740 key clear request; this seems to improve reliability of group key 1741 handshake for ndiswrapper & NDIS driver which seems to be suffering 1742 of some kind of timing issue when the keys are cleared again after 1743 association 1744 * changed driver interface API: 1745 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which 1746 version is being used (now, this is set to 2; previously, it was 1747 not defined) 1748 - pass pointer to private data structure to all calls 1749 - the new API is not backwards compatible; all in-tree driver 1750 interfaces has been converted to the new API 1751 * added support for controlling multiple interfaces (radios) per 1752 wpa_supplicant process; each interface needs to be listed on the 1753 command line (-c, -i, -D arguments) with -N as a separator 1754 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi) 1755 * added a workaround for EAP servers that incorrectly use same Id for 1756 sequential EAP packets 1757 * changed libpcap/libdnet configuration to use .config variable, 1758 CONFIG_DNET_PCAP, instead of requiring Makefile modification 1759 * improved downgrade attack detection in IE verification of msg 3/4: 1760 verify both WPA and RSN IEs, if present, not only the selected one; 1761 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or 1762 Probe Response frame, and RSN is enabled in wpa_supplicant 1763 configuration 1764 * fixed WPA msg 3/4 processing to allow Key Data field contain other 1765 IEs than just one WPA IE 1766 * added support for FreeBSD and driver interface for the BSD net80211 1767 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the 1768 required kernel mods have not yet been committed 1769 * made EAP workarounds configurable; enabled by default, can be 1770 disabled with network block option eap_workaround=0 1771 1772 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases) 1773 * resolved couple of interoperability issues with EAP-PEAPv1 and 1774 Phase 2 (inner EAP) fragment reassembly 1775 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the 1776 AP is using non-zero key index for the unicast key and key index zero 1777 for the broadcast key 1778 * driver_hostap: fixed IEEE 802.1X WEP key updates and 1779 re-authentication by allowing unencrypted EAPOL frames when not using 1780 WPA 1781 * added a new driver interface, 'wext', which uses only standard, 1782 driver independent functionality in Linux wireless extensions; 1783 currently, this can be used only for non-WPA IEEE 802.1X mode, but 1784 eventually, this is to be extended to support full WPA/WPA2 once 1785 Linux wireless extensions get support for this 1786 * added support for mode in which the driver is responsible for AP 1787 scanning and selection; this is disabled by default and can be 1788 enabled with global ap_scan=0 variable in wpa_supplicant.conf; 1789 this mode can be used, e.g., with generic 'wext' driver interface to 1790 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver 1791 supporting wireless extensions. 1792 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g., 1793 operation with an AP that does not include SSID in the Beacon frames) 1794 * added support for new EAP authentication methods: 1795 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP 1796 * added support for asking one-time-passwords from frontends (e.g., 1797 wpa_cli); this 'otp' command works otherwise like 'password' command, 1798 but the password is used only once and the frontend will be asked for 1799 a new password whenever a request from authenticator requires a 1800 password; this can be used with both EAP-OTP and EAP-GTC 1801 * changed wpa_cli to automatically re-establish connection so that it 1802 does not need to be re-started when wpa_supplicant is terminated and 1803 started again 1804 * improved user data (identity/password/otp) requests through 1805 frontends: process pending EAPOL packets after getting new 1806 information so that full authentication does not need to be 1807 restarted; in addition, send pending requests again whenever a new 1808 frontend is attached 1809 * changed control frontends to use a new directory for socket files to 1810 make it easier for wpa_cli to automatically select between interfaces 1811 and to provide access control for the control interface; 1812 wpa_supplicant.conf: ctrl_interface is now a path 1813 (/var/run/wpa_supplicant is the recommended path) and 1814 ctrl_interface_group can be used to select which group gets access to 1815 the control interface; 1816 wpa_cli: by default, try to connect to the first interface available 1817 in /var/run/wpa_supplicant; this path can be overriden with -p option 1818 and an interface can be selected with -i option (i.e., in most common 1819 cases, wpa_cli does not need to get any arguments) 1820 * added support for LEAP 1821 * added driver interface for Linux ndiswrapper 1822 * added priority option for network blocks in the configuration file; 1823 this allows networks to be grouped based on priority (the scan 1824 results are searched for matches with network blocks in this order) 1825 1826 2004-06-20 - v0.2.3 1827 * sort scan results to improve AP selection 1828 * fixed control interface socket removal for some error cases 1829 * improved scan requesting and authentication timeout 1830 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and 1831 TLS processing 1832 * PEAP version can now be forced with phase1="peapver=<ver>" 1833 (mostly for testing; by default, the highest version supported by 1834 both the Supplicant and Authentication Server is selected 1835 automatically) 1836 * added support for madwifi driver (Atheros ar521x) 1837 * added a workaround for cases where AP sets Install Tx/Rx bit for 1838 WPA Group Key messages when pairwise keys are used (without this, 1839 the Group Key would be used for Tx and the AP would drop frames 1840 from the station) 1841 * added GSM SIM/USIM interface for GSM authentication algorithm for 1842 EAP-SIM; this requires pcsc-lite 1843 * added support for ATMEL AT76C5XXx driver 1844 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator 1845 does not include key data in the EAPOL-Key frame (i.e., part of 1846 EAP keying material is used as data encryption key) 1847 * added support for using plaintext and static WEP networks 1848 (key_mgmt=NONE) 1849 1850 2004-05-31 - v0.2.2 1851 * added support for new EAP authentication methods: 1852 EAP-TTLS/EAP-MD5-Challenge 1853 EAP-TTLS/EAP-GTC 1854 EAP-TTLS/EAP-MSCHAPv2 1855 EAP-TTLS/EAP-TLS 1856 EAP-TTLS/MSCHAPv2 1857 EAP-TTLS/MSCHAP 1858 EAP-TTLS/PAP 1859 EAP-TTLS/CHAP 1860 EAP-PEAP/TLS 1861 EAP-PEAP/GTC 1862 EAP-PEAP/MD5-Challenge 1863 EAP-GTC 1864 EAP-SIM (not yet complete; needs GSM/SIM authentication interface) 1865 * added support for anonymous identity (to be used when identity is 1866 sent in plaintext; real identity will be used within TLS protected 1867 tunnel (e.g., with EAP-TTLS) 1868 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli 1869 * added support for requesting identity and password information using 1870 control interface; in other words, the password for EAP-PEAP or 1871 EAP-TTLS does not need to be included in the configuration file since 1872 a frontand (e.g., wpa_cli) can ask it from the user 1873 * improved RSN pre-authentication to use a candidate list and process 1874 all candidates from each scan; not only one per scan 1875 * fixed RSN IE and WPA IE capabilities field parsing 1876 * ignore Tx bit in GTK IE when Pairwise keys are used 1877 * avoid making new scan requests during IEEE 802.1X negotiation 1878 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant 1879 with TLS support (this replaces the included implementation with 1880 library code to save about 8 kB since the library code is needed 1881 anyway for TLS) 1882 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support 1883 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config) 1884 1885 2004-05-06 - v0.2.1 1886 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1) 1887 Supplicant 1888 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1] 1889 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf] 1890 - EAP-MD5 (cannot be used with WPA-RADIUS) 1891 [draft-ietf-eap-rfc2284bis-09.txt] 1892 - EAP-TLS [RFC 2716] 1893 - EAP-MSCHAPv2 (currently used only with EAP-PEAP) 1894 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt] 1895 [draft-kamath-pppext-eap-mschapv2-00.txt] 1896 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by 1897 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey) 1898 - new configuration file options: eap, identity, password, ca_cert, 1899 client_cert, privatekey, private_key_passwd 1900 - Xsupplicant is not required anymore, but it can be used by 1901 disabling the internal IEEE 802.1X Supplicant with -e command line 1902 option 1903 - this code is not included in the default build; Makefile need to 1904 be edited for this (uncomment lines for selected functionality) 1905 - EAP-TLS and EAP-PEAP require openssl libraries 1906 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..) 1907 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys 1908 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X 1909 EAPOL-Key frames instead of WPA key handshakes) 1910 * added support for IEEE 802.11i/RSN (WPA2) 1911 - improved PTK Key Handshake 1912 - PMKSA caching, pre-authentication 1913 * fixed wpa_supplicant to ignore possible extra data after WPA 1914 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using 1915 TPTK' error from message 3 of 4-Way Handshake in case the AP 1916 includes extra data after the EAPOL-Key) 1917 * added interface for external programs (frontends) to control 1918 wpa_supplicant 1919 - CLI example (wpa_cli) with interactive mode and command line 1920 mode 1921 - replaced SIGUSR1 status/statistics with the new control interface 1922 * made some feature compile time configurable 1923 - .config file for make 1924 - driver interfaces (hostap, hermes, ..) 1925 - EAPOL/EAP functions 1926 1927 2004-02-15 - v0.2.0 1928 * Initial version of wpa_supplicant 1929
