See README-P2P for more information. 514 * Many bugfixes. 515 5162010-04-18 - v0.7.2 517 * nl80211: fixed number of issues with roaming 518 * avoid unnecessary roaming if multiple APs with similar signal 519 strength are present in scan results 520 * add TLS client events and server probing to ease design of 521 automatic detection of EAP parameters 522 * add option for server certificate matching (SHA256 hash of the 523 certificate) instead of trusted CA certificate configuration 524 * bsd: Cleaned up driver wrapper and added various low-level 525 configuration options 526 * wpa_gui-qt4: do not show too frequent WPS AP available events as 527 tray messages 528 * TNC: fixed issues with fragmentation 529 * EAP-TNC: add Flags field into fragment acknowledgement (needed to 530 interoperate with other implementations; may potentially breaks 531 compatibility with older wpa_supplicant/hostapd versions) 532 * wpa_cli: added option for using a separate process to receive event 533 messages to reduce latency in showing these 534 (CFLAGS += -DCONFIG_WPA_CLI_FORK=y in .config to enable this) 535 * maximum BSS table size can now be configured (bss_max_count) 536 * BSSes to be included in the BSS table can be filtered based on 537 configured SSIDs to save memory (filter_ssids) 538 * fix number of issues with IEEE 802.11r/FT; this version is not 539 backwards compatible with old versions 540 * nl80211: add support for IEEE 802.11r/FT protocol (both over-the-air 541 and over-the-DS) 542 * add freq_list network configuration parameter to allow the AP 543 selection to filter out entries based on the operating channel 544 * add signal strength change events for bgscan; this allows more 545 dynamic changes to background scanning interval based on changes in 546 the signal strength with the current AP; this improves roaming within 547 ESS quite a bit, e.g., with bgscan="simple:30:-45:300" in the network 548 configuration block to request background scans less frequently when 549 signal strength remains good and to automatically trigger background 550 scans whenever signal strength drops noticeably 551 (this is currently only available with nl80211) 552 * add BSSID and reason code (if available) to disconnect event messages 553 * wpa_gui-qt4: more complete support for translating the GUI with 554 linguist and add German translation 555 * fix DH padding with internal crypto code (mainly, for WPS) 556 * do not trigger initial scan automatically anymore if there are no 557 enabled networks 558 5592010-01-16 - v0.7.1 560 * cleaned up driver wrapper API (struct wpa_driver_ops); the new API 561 is not fully backwards compatible, so out-of-tree driver wrappers 562 will need modifications 563 * cleaned up various module interfaces 564 * merge hostapd and wpa_supplicant developers' documentation into a 565 single document 566 * nl80211: use explicit deauthentication to clear cfg80211 state to 567 avoid issues when roaming between APs 568 * dbus: major design changes in the new D-Bus API 569 (fi.w1.wpa_supplicant1) 570 * nl80211: added support for IBSS networks 571 * added internal debugging mechanism with backtrace support and memory 572 allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y) 573 * added WPS ER unsubscription command to more cleanly unregister from 574 receiving UPnP events when ER is terminated 575 * cleaned up AP mode operations to avoid need for virtual driver_ops 576 wrapper 577 * added BSS table to maintain more complete scan result information 578 over multiple scans (that may include only partial results) 579 * wpa_gui-qt4: update Peers dialog information more dynamically while 580 the dialog is kept open 581 * fixed PKCS#12 use with OpenSSL 1.0.0 582 * driver_wext: Added cfg80211-specific optimization to avoid some 583 unnecessary scans and to speed up association 584 5852009-11-21 - v0.7.0 586 * increased wpa_cli ping interval to 5 seconds and made this 587 configurable with a new command line options (-G<seconds>) 588 * fixed scan buffer processing with WEXT to handle up to 65535 589 byte result buffer (previously, limited to 32768 bytes) 590 * allow multiple driver wrappers to be specified on command line 591 (e.g., -Dnl80211,wext); the first one that is able to initialize the 592 interface will be used 593 * added support for multiple SSIDs per scan request to optimize 594 scan_ssid=1 operations in ap_scan=1 mode (i.e., search for hidden 595 SSIDs); this requires driver support and can currently be used only 596 with nl80211 597 * added support for WPS USBA out-of-band mechanism with USB Flash 598 Drives (UFD) (CONFIG_WPS_UFD=y) 599 * driver_ndis: add PAE group address to the multicast address list to 600 fix wired IEEE 802.1X authentication 601 * fixed IEEE 802.11r key derivation function to match with the standard 602 (note: this breaks interoperability with previous version) [Bug 303] 603 * added better support for drivers that allow separate authentication 604 and association commands (e.g., mac80211-based Linux drivers with 605 nl80211; SME in wpa_supplicant); this allows over-the-air FT protocol 606 to be used (IEEE 802.11r) 607 * fixed SHA-256 based key derivation function to match with the 608 standard when using CCMP (for IEEE 802.11r and IEEE 802.11w) 609 (note: this breaks interoperability with previous version) [Bug 307] 610 * use shared driver wrapper files with hostapd 611 * added AP mode functionality (CONFIG_AP=y) with mode=2 in the network 612 block; this can be used for open and WPA2-Personal networks 613 (optionally, with WPS); this links in parts of hostapd functionality 614 into wpa_supplicant 615 * wpa_gui-qt4: added new Peers dialog to show information about peers 616 (other devices, including APs and stations, etc. in the neighborhood) 617 * added support for WPS External Registrar functionality (configure APs 618 and enroll new devices); can be used with wpa_gui-qt4 Peers dialog 619 and wpa_cli commands wps_er_start, wps_er_stop, wps_er_pin, 620 wps_er_pbc, wps_er_learn 621 (this can also be used with a new 'none' driver wrapper if no 622 wireless device or IEEE 802.1X on wired is needed) 623 * driver_nl80211: multiple updates to provide support for new Linux 624 nl80211/mac80211 functionality 625 * updated management frame protection to use IEEE Std 802.11w-2009 626 * fixed number of small WPS issues and added workarounds to 627 interoperate with common deployed broken implementations 628 * added support for NFC out-of-band mechanism with WPS 629 * driver_ndis: fixed wired IEEE 802.1X authentication with PAE group 630 address frames 631 * added preliminary support for IEEE 802.11r RIC processing 632 * added support for specifying subset of enabled frequencies to scan 633 (scan_freq option in the network configuration block); this can speed 634 up scanning process considerably if it is known that only a small 635 subset of channels is actually used in the network (this is currently 636 supported only with -Dnl80211) 637 * added a workaround for race condition between receiving the 638 association event and the following EAPOL-Key 639 * added background scan and roaming infrastructure to allow 640 network-specific optimizations to be used to improve roaming within 641 an ESS (same SSID) 642 * added new DBus interface (fi.w1.wpa_supplicant1) 643 6442009-01-06 - v0.6.7 645 * added support for Wi-Fi Protected Setup (WPS) 646 (wpa_supplicant can now be configured to act as a WPS Enrollee to 647 enroll credentials for a network using PIN and PBC methods; in 648 addition, wpa_supplicant can act as a wireless WPS Registrar to 649 configure an AP); WPS support can be enabled by adding CONFIG_WPS=y 650 into .config and setting the runtime configuration variables in 651 wpa_supplicant.conf (see WPS section in the example configuration 652 file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to 653 manage WPS negotiation; see README-WPS for more details 654 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf) 655 * added support for using driver_test over UDP socket 656 * fixed PEAPv0 Cryptobinding interoperability issue with Windows Server 657 2008 NPS; optional cryptobinding is now enabled (again) by default 658 * fixed PSK editing in wpa_gui 659 * changed EAP-GPSK to use the IANA assigned EAP method type 51 660 * added a Windows installer that includes WinPcap and all the needed 661 DLLs; in addition, it set up the registry automatically so that user 662 will only need start wpa_gui to get prompted to start the wpasvc 663 servide and add a new interface if needed through wpa_gui dialog 664 * updated management frame protection to use IEEE 802.11w/D7.0 665 6662008-11-23 - v0.6.6 667 * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA 668 (can be used to simulate test SIM/USIM card with a known private key; 669 enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config 670 and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration) 671 * added a new network configuration option, wpa_ptk_rekey, that can be 672 used to enforce frequent PTK rekeying, e.g., to mitigate some attacks 673 against TKIP deficiencies 674 * added an optional mitigation mechanism for certain attacks against 675 TKIP by delaying Michael MIC error reports by a random amount of time 676 between 0 and 60 seconds; this can be enabled with a build option 677 CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config 678 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits, 679 not bytes 680 * updated OpenSSL code for EAP-FAST to use an updated version of the 681 session ticket overriding API that was included into the upstream 682 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is 683 needed with that version anymore) 684 * updated userspace MLME instructions to match with the current Linux 685 mac80211 implementation; please also note that this can only be used 686 with driver_nl80211.c (the old code from driver_wext.c was removed) 687 * added support (Linux only) for RoboSwitch chipsets (often found in 688 consumer grade routers); driver interface 'roboswitch' 689 * fixed canceling of PMKSA caching when using drivers that generate 690 RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know 691 about 692 6932008-11-01 - v0.6.5 694 * added support for SHA-256 as X.509 certificate digest when using the 695 internal X.509/TLSv1 implementation 696 * updated management frame protection to use IEEE 802.11w/D6.0 697 * added support for using SHA256-based stronger key derivation for WPA2 698 (IEEE 802.11w) 699 * fixed FT (IEEE 802.11r) authentication after a failed association to 700 use correct FTIE 701 * added support for configuring Phase 2 (inner/tunneled) authentication 702 method with wpa_gui-qt4 703 7042008-08-10 - v0.6.4 705 * added support for EAP Sequences in EAP-FAST Phase 2 706 * added support for using TNC with EAP-FAST 707 * added driver_ps3 for the PS3 Linux wireless driver 708 * added support for optional cryptobinding with PEAPv0 709 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to 710 allow fallback to full handshake if server rejects PAC-Opaque 711 * added fragmentation support for EAP-TNC 712 * added support for parsing PKCS #8 formatted private keys into the 713 internal TLS implementation (both PKCS #1 RSA key and PKCS #8 714 encapsulated RSA key can now be used) 715 * added option of using faster, but larger, routines in the internal 716 LibTomMath (for internal TLS implementation) to speed up DH and RSA 717 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y) 718 * fixed race condition between disassociation event and group key 719 handshake to avoid getting stuck in incorrect state [Bug 261] 720 * fixed opportunistic key caching (proactive_key_caching) 721 7222008-02-22 - v0.6.3 723 * removed 'nai' and 'eappsk' network configuration variables that were 724 previously used for configuring user identity and key for EAP-PSK, 725 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the 726 replacement for 'nai' (if old configuration used a separate 727 'identity' value, that would now be configured as 728 'anonymous_identity'). 'password' field is now used as the 729 replacement for 'eappsk' (it can also be set using hexstring to 730 present random binary data) 731 * removed '-w' command line parameter (wait for interface to be added, 732 if needed); cleaner way of handling this functionality is to use an 733 external mechanism (e.g., hotplug scripts) that start wpa_supplicant 734 when an interface is added 735 * updated FT support to use the latest draft, IEEE 802.11r/D9.0 736 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for 737 indicating when new scan results become available 738 * added new ctrl_iface command, BSS, to allow scan results to be 739 fetched without hitting the message size limits (this command 740 can be used to iterate through the scan results one BSS at the time) 741 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION 742 attributes in EAP-SIM Start/Response when using fast reauthentication 743 * fixed EAPOL not to end up in infinite loop when processing dynamic 744 WEP keys with IEEE 802.1X 745 * fixed problems in getting NDIS events from WMI on Windows 2000 746 7472008-01-01 - v0.6.2 748 * added support for Makefile builds to include debug-log-to-a-file 749 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line) 750 * fixed EAP-SIM and EAP-AKA message parser to validate attribute 751 lengths properly to avoid potential crash caused by invalid messages 752 * added data structure for storing allocated buffers (struct wpabuf); 753 this does not affect wpa_supplicant usage, but many of the APIs 754 changed and various interfaces (e.g., EAP) is not compatible with old 755 versions 756 * added support for protecting EAP-AKA/Identity messages with 757 AT_CHECKCODE (optional feature in RFC 4187) 758 * added support for protected result indication with AT_RESULT_IND for 759 EAP-SIM and EAP-AKA (phase1="result_ind=1") 760 * added driver_wext workaround for race condition between scanning and 761 association with drivers that take very long time to scan all 762 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now 763 using a longer hardcoded timeout for the scan if the driver supports 764 notifications for scan completion (SIOCGIWSCAN event); this helps, 765 e.g., in cases where wpa_supplicant and madwifi driver ended up in 766 loop where the driver did not even try to associate 767 * stop EAPOL timer tick when no timers are in use in order to reduce 768 power consumption (no need to wake up the process once per second) 769 [Bug 237] 770 * added support for privilege separation (run only minimal part of 771 wpa_supplicant functionality as root and rest as unprivileged, 772 non-root process); see 'Privilege separation' in README for details; 773 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y 774 in .config 775 * changed scan results data structure to include all information 776 elements to make it easier to support new IEs; old get_scan_result() 777 driver_ops is still supported for backwards compatibility (results 778 are converted internally to the new format), but all drivers should 779 start using the new get_scan_results2() to make them more likely to 780 work with new features 781 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4 782 application, i.e., it does not require Qt3Support anymore; Windows 783 binary of wpa_gui.exe is now from this directory and only requires 784 QtCore4.dll and QtGui4.dll libraries 785 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs 786 available as a separate package to make wpa_gui installation easier: 787 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip 788 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt); 789 only shared key/password authentication is supported in this version 790 7912007-11-24 - v0.6.1 792 * added support for configuring password as NtPasswordHash 793 (16-byte MD4 hash of password) in hash:<32 hex digits> format 794 * added support for fallback from abbreviated TLS handshake to 795 full handshake when using EAP-FAST (e.g., due to an expired 796 PAC-Opaque) 797 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 798 draft (draft-ietf-emu-eap-gpsk-07.txt) 799 * added support for drivers that take care of RSN 4-way handshake 800 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and 801 WPA_ALG_PMK in set_key) 802 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in 803 .config); this version supports only ap_scan=2 mode and allow the 804 driver to take care of the 4-way handshake 805 * fixed a buffer overflow in parsing TSF from scan results when using 806 driver_wext.c with a driver that includes the TSF (e.g., iwl4965) 807 [Bug 232] 808 * updated FT support to use the latest draft, IEEE 802.11r/D8.0 809 * fixed an integer overflow issue in the ASN.1 parser used by the 810 (experimental) internal TLS implementation to avoid a potential 811 buffer read overflow 812 * fixed a race condition with -W option (wait for a control interface 813 monitor before starting) that could have caused the first messages to 814 be lost 815 * added support for processing TNCC-TNCS-Messages to report 816 recommendation (allow/none/isolate) when using TNC [Bug 243] 817 8182007-05-28 - v0.6.0 819 * added network configuration parameter 'frequency' for setting 820 initial channel for IBSS (adhoc) networks 821 * added experimental IEEE 802.11r/D6.0 support 822 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48 823 * updated EAP-PSK to use the IANA-allocated EAP type 47 824 * fixed EAP-PAX key derivation 825 * fixed EAP-PSK bit ordering of the Flags field 826 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in 827 tunnelled identity request (previously, the identifier from the outer 828 method was used, not the tunnelled identifier which could be 829 different) 830 * added support for fragmentation of outer TLS packets during Phase 2 831 of EAP-PEAP/TTLS/FAST 832 * fixed EAP-TTLS AVP parser processing for too short AVP lengths 833 * added support for EAP-FAST authentication with inner methods that 834 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported 835 for PAC provisioning) 836 * added support for authenticated EAP-FAST provisioning 837 * added support for configuring maximum number of EAP-FAST PACs to 838 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string) 839 * added support for storing EAP-FAST PACs in binary format 840 (fast_pac_format=binary in phase1 string) 841 * fixed dbus ctrl_iface to validate message interface before 842 dispatching to avoid a possible segfault [Bug 190] 843 * fixed PeerKey key derivation to use the correct PRF label 844 * updated Windows binary build to link against OpenSSL 0.9.8d and 845 added support for EAP-FAST 846 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 847 draft (draft-ietf-emu-eap-gpsk-04.txt) 848 * fixed EAP-AKA Notification processing to allow Notification to be 849 processed after AKA Challenge response has been sent 850 * updated to use IEEE 802.11w/D2.0 for management frame protection 851 (still experimental) 852 * fixed EAP-TTLS implementation not to crash on use of freed memory 853 if TLS library initialization fails 854 * added support for EAP-TNC (Trusted Network Connect) 855 (this version implements the EAP-TNC method and EAP-TTLS changes 856 needed to run two methods in sequence (IF-T) and the IF-IMC and 857 IF-TNCCS interfaces from TNCC) 858 8592006-11-24 - v0.5.6 860 * added experimental, integrated TLSv1 client implementation with the 861 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by 862 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in 863 .config); this can be useful, e.g., if the target system does not 864 have a suitable TLS library and a minimal code size is required 865 (total size of this internal TLS/crypto code is bit under 50 kB on 866 x86 and the crypto code is shared by rest of the supplicant so some 867 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB) 868 * removed STAKey handshake since PeerKey handshake has replaced it in 869 IEEE 802.11ma and there are no known deployments of STAKey 870 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 871 draft (draft-ietf-emu-eap-gpsk-01.txt) 872 * added preliminary implementation of IEEE 802.11w/D1.0 (management 873 frame protection) 874 (Note: this requires driver support to work properly.) 875 (Note2: IEEE 802.11w is an unapproved draft and subject to change.) 876 * fixed Windows named pipes ctrl_iface to not stop listening for 877 commands if client program opens a named pipe and closes it 878 immediately without sending a command 879 * fixed USIM PIN status determination for the case that PIN is not 880 needed (this allows EAP-AKA to be used with USIM cards that do not 881 use PIN) 882 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to 883 be used with cards that do not support file selection based on 884 partial AID 885 * added support for matching the subjectAltName of the authentication 886 server certificate against multiple name components (e.g., 887 altsubject_match="DNS:server.example.com;DNS:server2.example.com") 888 * fixed EAP-SIM/AKA key derivation for re-authentication case (only 889 affects IEEE 802.1X with dynamic WEP keys) 890 * changed ctrl_iface network configuration 'get' operations to not 891 return password/key material; if these fields are requested, "*" 892 will be returned if the password/key is set, but the value of the 893 parameter is not exposed 894 8952006-08-27 - v0.5.5 896 * added support for building Windows version with UNICODE defined 897 (wide-char functions) 898 * driver_ndis: fixed static WEP configuration to avoid race condition 899 issues with some NDIS drivers between association and setting WEP 900 keys 901 * driver_ndis: added validation for IELength value in scan results to 902 avoid crashes when using buggy NDIS drivers [Bug 165] 903 * fixed Release|Win32 target in the Visual Studio project files 904 (previously, only Debug|Win32 target was set properly) 905 * changed control interface API call wpa_ctrl_pending() to allow it to 906 return -1 on error (e.g., connection lost); control interface clients 907 will need to make sure that they verify that the value is indeed >0 908 when determining whether there are pending messages 909 * added an alternative control interface backend for Windows targets: 910 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default 911 control interface mechanism for Windows builds (previously, UDP to 912 localhost was used) 913 * changed ctrl_interface configuration for UNIX domain sockets: 914 - deprecated ctrl_interface_group variable (it may be removed in 915 future versions) 916 - allow both directory and group be configured with ctrl_interface 917 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel 918 - ctrl_interface=/var/run/wpa_supplicant is still supported for the 919 case when group is not changed 920 * added support for controlling more than one interface per process in 921 Windows version 922 * added a workaround for a case where the AP is using unknown address 923 (e.g., MAC address of the wired interface) as the source address for 924 EAPOL-Key frames; previously, that source address was used as the 925 destination for EAPOL-Key frames and in key derivation; now, BSSID is 926 used even if the source address does not match with it 927 (this resolves an interoperability issue with Thomson SpeedTouch 580) 928 * added a workaround for UDP-based control interface (which was used in 929 Windows builds before this release) to prevent packets with forged 930 addresses from being accepted as local control requests 931 * removed ndis_events.cpp and possibility of using external 932 ndis_events.exe; C version (ndis_events.c) is fully functional and 933 there is no desire to maintain two separate versions of this 934 implementation 935 * ndis_events: Changed NDIS event notification design to use WMI to 936 learn the adapter description through Win32_PnPEntity class; this 937 should fix some cases where the adapter name was not recognized 938 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500 939 USB) [Bug 113] 940 * fixed selection of the first network in ap_scan=2 mode; previously, 941 wpa_supplicant could get stuck in SCANNING state when only the first 942 network for enabled (e.g., after 'wpa_cli select_network 0') 943 * winsvc: added support for configuring ctrl_interface parameters in 944 registry (ctrl_interface string value in 945 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is 946 required to enable control interface (previously, this was hardcoded 947 to be enabled) 948 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4 949 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format 950 9512006-06-20 - v0.5.4 952 * fixed build with CONFIG_STAKEY=y [Bug 143] 953 * added support for doing MLME (IEEE 802.11 management frame 954 processing) in wpa_supplicant when using Devicescape IEEE 802.11 955 stack (wireless-dev.git tree) 956 * added a new network block configuration option, fragment_size, to 957 configure the maximum EAP fragment size 958 * driver_ndis: Disable WZC automatically for the selected interface to 959 avoid conflicts with two programs trying to control the radio; WZC 960 will be re-enabled (if it was enabled originally) when wpa_supplicant 961 is terminated 962 * added an experimental TLSv1 client implementation 963 (CONFIG_TLS=internal) that can be used instead of an external TLS 964 library, e.g., to reduce total size requirement on systems that do 965 not include any TLS library by default (this is not yet complete; 966 basic functionality is there, but certificate validation is not yet 967 included) 968 * added PeerKey handshake implementation for IEEE 802.11e 969 direct link setup (DLS) to replace STAKey handshake 970 * fixed WPA PSK update through ctrl_iface for the case where the old 971 PSK was derived from an ASCII passphrase and the new PSK is set as 972 a raw PSK (hex string) 973 * added new configuration option for identifying which network block 974 was used (id_str in wpa_supplicant.conf; included on 975 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental 976 variable in wpa_cli action scripts; in addition WPA_ID variable is 977 set to the current unique identifier that wpa_supplicant assigned 978 automatically for the network and that can be used with 979 GET_NETWORK/SET_NETWORK ctrl_iface commands) 980 * wpa_cli action script is now called only when the connect/disconnect 981 status changes or when associating with a different network 982 * fixed configuration parser not to remove CCMP from group cipher list 983 if WPA-None (adhoc) is used (pairwise=NONE in that case) 984 * fixed integrated NDIS events processing not to hang the process due 985 to a missed change in eloop_win.c API in v0.5.3 [Bug 155] 986 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK, 987 draft-clancy-emu-eap-shared-secret-00.txt) 988 * added Microsoft Visual Studio 2005 solution and project files for 989 build wpa_supplicant for Windows (see vs2005 subdirectory) 990 * eloop_win: fixed unregistration of Windows events 991 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet 992 at the end of RSN pre-authentication and added unregistration of 993 a Windows event to avoid getting eloop_win stuck with an invalid 994 handle 995 * driver_ndis: added support for selecting AP based on BSSID 996 * added new environmental variable for wpa_cli action scripts: 997 WPA_CTRL_DIR is the current control interface directory 998 * driver_ndis: added support for using NDISUIO instead of WinPcap for 999 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new 1000 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build 1001 wpa_supplicant without requiring WinPcap; note that using NDISUIO 1002 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows 1003 only one application to open the device 1004 * changed NDIS driver naming to only include device GUID, e.g., 1005 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap 1006 specific \Device\NPF_ prefix before the GUID; the prefix is still 1007 allowed for backwards compatibility, but it is not required anymore 1008 when specifying the interface 1009 * driver_ndis: re-initialize driver interface is the adapter is removed 1010 and re-inserted [Bug 159] 1011 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on 1012 big endian hosts [Bug 146] 1013 10142006-04-27 - v0.5.3 1015 * fixed EAP-GTC response to include correct user identity when run as 1016 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2) 1017 * driver_ndis: Fixed encryption mode configuration for unencrypted 1018 networks (some NDIS drivers ignored this, but others, e.g., Broadcom, 1019 refused to associate with open networks) [Bug 106] 1020 * driver_ndis: use BSSID OID polling to detect when IBSS network is 1021 formed even when ndis_events code is included since some NDIS drivers 1022 do not generate media connect events in IBSS mode 1023 * config_winreg: allow global ctrl_interface parameter to be configured 1024 in Windows registry 1025 * config_winreg: added support for saving configuration data into 1026 Windows registry 1027 * added support for controlling network device operational state 1028 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see 1029 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client 1030 that can use this information) 1031 * driver_wext: added support for WE-21 change to SSID configuration 1032 * driver_wext: fixed privacy configuration for static WEP keys mode 1033 [Bug 140] 1034 * added an optional driver_ops callback for MLME-SETPROTECTION.request 1035 primitive 1036 * added support for EAP-SAKE (no EAP method number allocated yet, so 1037 this is using the same experimental type 255 as EAP-PSK) 1038 * added support for dynamically loading EAP methods (.so files) instead 1039 of requiring them to be statically linked in; this is disabled by 1040 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information 1041 on how to use this) 1042 10432006-03-19 - v0.5.2 1044 * do not try to use USIM APDUs when initializing PC/SC for SIM card 1045 access for a network that has not enabled EAP-AKA 1046 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in 1047 v0.5.1 due to the new support for expanded EAP types) 1048 * added support for generating EAP Expanded Nak 1049 * try to fetch scan results once before requesting new scan when 1050 starting up in ap_scan=1 mode (this can speed up initial association 1051 a lot with, e.g., madwifi-ng driver) 1052 * added support for receiving EAPOL frames from a Linux bridge 1053 interface (-bbr0 on command line) 1054 * fixed EAPOL re-authentication for sessions that used PMKSA caching 1055 * changed EAP method registration to use a dynamic list of methods 1056 instead of a static list generated at build time 1057 * fixed PMKSA cache deinitialization not to use freed memory when 1058 removing PMKSA entries 1059 * fixed a memory leak in EAP-TTLS re-authentication 1060 * reject WPA/WPA2 message 3/4 if it does not include any valid 1061 WPA/RSN IE 1062 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg 1063 if the driver does not support SIOCSIWAUTH 1064 10652006-01-29 - v0.5.1 1066 * driver_test: added better support for multiple APs and STAs by using 1067 a directory with sockets that include MAC address for each device in 1068 the name (driver_param=test_dir=/tmp/test) 1069 * added support for EAP expanded type (vendor specific EAP methods) 1070 * added AP_SCAN command into ctrl_iface so that ap_scan configuration 1071 option can be changed if needed 1072 * wpa_cli/wpa_gui: skip non-socket files in control directory when 1073 using UNIX domain sockets; this avoids selecting an incorrect 1074 interface (e.g., a PID file could be in this directory, even though 1075 use of this directory for something else than socket files is not 1076 recommended) 1077 * fixed TLS library deinitialization after RSN pre-authentication not 1078 to disable TLS library for normal authentication 1079 * driver_wext: Remove null-termination from SSID length if the driver 1080 used it; some Linux drivers do this and they were causing problems in 1081 wpa_supplicant not finding matching configuration block. This change 1082 would break a case where the SSID actually ends in '\0', but that is 1083 not likely to happen in real use. 1084 * fixed PMKSA cache processing not to trigger deauthentication if the 1085 current PMKSA cache entry is replaced with a valid new entry 1086 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes 1087 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or 1088 ap_scan=2) 1089 10902005-12-18 - v0.5.0 (beginning of 0.5.x development releases) 1091 * added experimental STAKey handshake implementation for IEEE 802.11e 1092 direct link setup (DLS); note: this is disabled by default in both 1093 build and runtime configuration (can be enabled with CONFIG_STAKEY=y 1094 and stakey=1) 1095 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to 1096 decrypt AT_ENCR_DATA attributes correctly 1097 * fixed EAP-AKA to allow resynchronization within the same session 1098 * made code closer to ANSI C89 standard to make it easier to port to 1099 other C libraries and compilers 1100 * started moving operating system or C library specific functions into 1101 wrapper functions defined in os.h and implemented in os_*.c to make 1102 code more portable 1103 * wpa_supplicant can now be built with Microsoft Visual C++ 1104 (e.g., with the freely available Toolkit 2003 version or Visual 1105 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an 1106 example makefile for nmake 1107 * added support for using Windows registry for command line parameters 1108 (CONFIG_MAIN=main_winsvc) and configuration data 1109 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry 1110 contents; this version can be run both as a Windows service and as a 1111 normal application; 'wpasvc.exe app' to start as applicant, 1112 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service, 1113 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to 1114 unregister a service 1115 * made it possible to link ndis_events.exe functionality into 1116 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED 1117 * added better support for multiple control interface backends 1118 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported 1119 * fixed PC/SC code to use correct length for GSM AUTH command buffer 1120 and to not use pioRecvPci with SCardTransmit() calls; these were not 1121 causing visible problems with pcsc-lite, but Windows Winscard.dll 1122 refused the previously used parameters; this fixes EAP-SIM and 1123 EAP-AKA authentication using SIM/USIM card under Windows 1124 * added new event loop implementation for Windows using 1125 WaitForMultipleObject() instead of select() in order to allow waiting 1126 for non-socket objects; this can be selected with 1127 CONFIG_ELOOP=eloop_win in .config 1128 * added support for selecting l2_packet implementation in .config 1129 (CONFIG_L2_PACKET; following options are available now: linux, pcap, 1130 winpcap, freebsd, none) 1131 * added new l2_packet implementation for WinPcap 1132 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to 1133 reduce latency in EAPOL receive processing from about 100 ms to about 1134 3 ms 1135 * added support for EAP-FAST key derivation using other ciphers than 1136 RC4-128-SHA for authentication and AES128-SHA for provisioning 1137 * added support for configuring CA certificate as DER file and as a 1138 configuration blob 1139 * fixed private key configuration as configuration blob and added 1140 support for using PKCS#12 as a blob 1141 * tls_gnutls: added support for using PKCS#12 files; added support for 1142 session resumption 1143 * added support for loading trusted CA certificates from Windows 1144 certificate store: ca_cert="cert_store://<name>", where <name> is 1145 likely CA (Intermediate CA certificates) or ROOT (root certificates) 1146 * added C version of ndis_events.cpp and made it possible to build this 1147 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more 1148 easily on cross-compilation builds 1149 * added wpasvc.exe into Windows binary release; this is an alternative 1150 version of wpa_supplicant.exe with configuration backend using 1151 Windows registry and with the entry point designed to run as a 1152 Windows service 1153 * integrated ndis_events.exe functionality into wpa_supplicant.exe and 1154 wpasvc.exe and removed this additional tool from the Windows binary 1155 release since it is not needed anymore 1156 * load winscard.dll functions dynamically when building with MinGW 1157 since MinGW does not yet include winscard library 1158 11592005-11-20 - v0.4.7 (beginning of 0.4.x stable releases) 1160 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap 1161 and WinPcap to receive frames sent to PAE group address 1162 * disable EAP state machine when IEEE 802.1X authentication is not used 1163 in order to get rid of bogus "EAP failed" messages 1164 * fixed OpenSSL error reporting to go through all pending errors to 1165 avoid confusing reports of old errors being reported at later point 1166 during handshake 1167 * fixed configuration file updating to not write empty variables 1168 (e.g., proto or key_mgmt) that the file parser would not accept 1169 * fixed ADD_NETWORK ctrl_iface command to use the same default values 1170 for variables as empty network definitions read from config file 1171 would get 1172 * fixed EAP state machine to not discard EAP-Failure messages in many 1173 cases (e.g., during TLS handshake) 1174 * fixed a infinite loop in private key reading if the configured file 1175 cannot be parsed successfully 1176 * driver_madwifi: added support for madwifi-ng 1177 * wpa_gui: do not display password/PSK field contents 1178 * wpa_gui: added CA certificate configuration 1179 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID 1180 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if 1181 the new AP is using different WPA/RSN IE 1182 * use longer timeout for IEEE 802.11 association to avoid problems with 1183 drivers that may take more than five second to associate 1184 11852005-10-27 - v0.4.6 1186 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in 1187 RSN IE, but WPA IE would match with wpa_supplicant configuration 1188 * added support for named configuration blobs in order to avoid having 1189 to use file system for external files (e.g., certificates); 1190 variables can be set to "blob://<blob name>" instead of file path to 1191 use a named blob; supported fields: pac_file, client_cert, 1192 private_key 1193 * fixed RSN pre-authentication (it was broken in the clean up of WPA 1194 state machine interface in v0.4.5) 1195 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make 1196 sure the driver configures broadcast decryption correctly 1197 * added ca_path (and ca_path2) configuration variables that can be used 1198 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the 1199 system-wide trusted CA list 1200 * added support for starting wpa_supplicant without a configuration 1201 file (-C argument must be used to set ctrl_interface parameter for 1202 this case; in addition, -p argument can be used to provide 1203 driver_param; these new arguments can also be used with a 1204 configuration to override the values from the configuration) 1205 * added global control interface that can be optionally used for adding 1206 and removing network interfaces dynamically (-g command line argument 1207 for both wpa_supplicant and wpa_cli) without having to restart 1208 wpa_supplicant process 1209 * wpa_gui: 1210 - try to save configuration whenever something is modified 1211 - added WEP key configuration 1212 - added possibility to edit the current network configuration 1213 * driver_ndis: fixed driver polling not to increase frequency on each 1214 received EAPOL frame due to incorrectly cancelled timeout 1215 * added simple configuration file examples (in examples subdirectory) 1216 * fixed driver_wext.c to filter wireless events based on ifindex to 1217 avoid interfaces receiving events from other interfaces 1218 * delay sending initial EAPOL-Start couple of seconds to speed up 1219 authentication for the most common case of Authenticator starting 1220 EAP authentication immediately after association 1221 12222005-09-25 - v0.4.5 1223 * added a workaround for clearing keys with ndiswrapper to allow 1224 roaming from WPA enabled AP to plaintext one 1225 * added docbook documentation (doc/docbook) that can be used to 1226 generate, e.g., man pages 1227 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for 1228 PF_PACKET in order to prepare for network devices that do not use 1229 Ethernet headers (e.g., network stack with native IEEE 802.11 frames) 1230 * use receipt of EAPOL-Key frame as a lower layer success indication 1231 for EAP state machine to allow recovery from dropped EAP-Success 1232 frame 1233 * cleaned up internal EAPOL frame processing by not including link 1234 layer (Ethernet) header during WPA and EAPOL/EAP processing; this 1235 header is added only when transmitted the frame; this makes it easier 1236 to use wpa_supplicant on link layers that use different header than 1237 Ethernet 1238 * updated EAP-PSK to use draft 9 by default since this can now be 1239 tested with hostapd; removed support for draft 3, including 1240 server_nai configuration option from network blocks 1241 * driver_wired: add PAE address to the multicast address list in order 1242 to be able to receive EAPOL frames with drivers that do not include 1243 these multicast addresses by default 1244 * driver_wext: add support for WE-19 1245 * added support for multiple configuration backends (CONFIG_BACKEND 1246 option); currently, only 'file' is supported (i.e., the format used 1247 in wpa_supplicant.conf) 1248 * added support for updating configuration ('wpa_cli save_config'); 1249 this is disabled by default and can be enabled with global 1250 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli 1251 and wpa_gui to store the configuration changes in a permanent store 1252 * added GET_NETWORK ctrl_iface command 1253 (e.g., 'wpa_cli get_network 0 ssid') 1254 12552005-08-21 - v0.4.4 1256 * replaced OpenSSL patch for EAP-FAST support 1257 (openssl-tls-extensions.patch) with a more generic and correct 1258 patch (the new patch is not compatible with the previous one, so the 1259 OpenSSL library will need to be patched with the new patch in order 1260 to be able to build wpa_supplicant with EAP-FAST support) 1261 * added support for using Windows certificate store (through CryptoAPI) 1262 for client certificate and private key operations (EAP-TLS) 1263 (see wpa_supplicant.conf for more information on how to configure 1264 this with private_key) 1265 * ported wpa_gui to Windows 1266 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be 1267 built with the open source version of the Qt4 for Windows 1268 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used 1269 with drivers that do not support WPA 1270 * ndis_events: fixed Windows 2000 support 1271 * added support for enabling/disabling networks from the list of all 1272 configured networks ('wpa_cli enable_network <network id>' and 1273 'wpa_cli disable_network <network id>') 1274 * added support for adding and removing network from the current 1275 configuration ('wpa_cli add_network' and 'wpa_cli remove_network 1276 <network id>'); added networks are disabled by default and they can 1277 be enabled with enable_network command once the configuration is done 1278 for the new network; note: configuration file is not yet updated, so 1279 these new networks are lost when wpa_supplicant is restarted 1280 * added support for setting network configuration parameters through 1281 the control interface, for example: 1282 wpa_cli set_network 0 ssid "\"my network\"" 1283 * fixed parsing of strings that include both " and # within double 1284 quoted area (e.g., "start"#end") 1285 * added EAP workaround for PEAP session resumption: allow outer, 1286 i.e., not tunneled, EAP-Success to terminate session since; this can 1287 be disabled with eap_workaround=0 1288 (this was allowed for PEAPv1 before, but now it is also allowed for 1289 PEAPv0 since at least one RADIUS authentication server seems to be 1290 doing this for PEAPv0, too) 1291 * wpa_gui: added preliminary support for adding new networks to the 1292 wpa_supplicant configuration (double click on the scan results to 1293 open network configuration) 1294 12952005-06-26 - v0.4.3 1296 * removed interface for external EAPOL/EAP supplicant (e.g., 1297 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required 1298 anymore and is unlikely to be used by anyone 1299 * driver_ndis: fixed WinPcap 3.0 support 1300 * fixed build with CONFIG_DNET_PCAP=y on Linux 1301 * l2_packet: moved different implementations into separate files 1302 (l2_packet_*.c) 1303 13042005-06-12 - v0.4.2 1305 * driver_ipw: updated driver structures to match with ipw2200-1.0.4 1306 (note: ipw2100-1.1.0 is likely to require an update to work with 1307 this) 1308 * added support for using ap_scan=2 mode with multiple network blocks; 1309 wpa_supplicant will go through the networks one by one until the 1310 driver reports a successful association; this uses the same order for 1311 networks as scan_ssid=1 scans, i.e., the priority field is ignored 1312 and the network block order in the file is used instead 1313 * fixed a potential issue in RSN pre-authentication ending up using 1314 freed memory if pre-authentication times out 1315 * added support for matching alternative subject name extensions of the 1316 authentication server certificate; new configuration variables 1317 altsubject_match and altsubject_match2 1318 * driver_ndis: added support for IEEE 802.1X authentication with wired 1319 NDIS drivers 1320 * added support for querying private key password (EAP-TLS) through the 1321 control interface (wpa_cli/wpa_gui) if one is not included in the 1322 configuration file 1323 * driver_broadcom: fixed couple of memory leaks in scan result 1324 processing 1325 * EAP-PAX is now registered as EAP type 46 1326 * fixed EAP-PAX MAC calculation 1327 * fixed EAP-PAX CK and ICK key derivation 1328 * added support for using password with EAP-PAX (as an alternative to 1329 entering key with eappsk); SHA-1 hash of the password will be used as 1330 the key in this case 1331 * added support for arbitrary driver interface parameters through the 1332 configuration file with a new driver_param field; this adds a new 1333 driver_ops function set_param() 1334 * added possibility to override l2_packet module with driver interface 1335 API (new send_eapol handler); this can be used to implement driver 1336 specific TX/RX functions for EAPOL frames 1337 * fixed ctrl_interface_group processing for the case where gid is 1338 entered as a number, not group name 1339 * driver_test: added support for testing hostapd with wpa_supplicant 1340 by using test driver interface without any kernel drivers or network 1341 cards 1342 13432005-05-22 - v0.4.1 1344 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL 1345 packets to be encrypted; this was apparently broken by the changed 1346 ioctl order in v0.4.0 1347 * driver_madwifi: added preliminary support for compiling against 'BSD' 1348 branch of madwifi CVS tree 1349 * added support for EAP-MSCHAPv2 password retries within the same EAP 1350 authentication session 1351 * added support for password changes with EAP-MSCHAPv2 (used when the 1352 password has expired) 1353 * added support for reading additional certificates from PKCS#12 files 1354 and adding them to the certificate chain 1355 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys 1356 were used 1357 * fixed a possible double free in EAP-TTLS fast-reauthentication when 1358 identity or password is entered through control interface 1359 * display EAP Notification messages to user through control interface 1360 with "CTRL-EVENT-EAP-NOTIFICATION" prefix 1361 * added GUI version of wpa_cli, wpa_gui; this is not build 1362 automatically with 'make'; use 'make wpa_gui' to build (this requires 1363 Qt development tools) 1364 * added 'disconnect' command to control interface for setting 1365 wpa_supplicant in state where it will not associate before 1366 'reassociate' command has been used 1367 * added support for selecting a network from the list of all configured 1368 networks ('wpa_cli select_network <network id>'; this disabled all 1369 other networks; to re-enable, 'wpa_cli select_network any') 1370 * added support for getting scan results through control interface 1371 * added EAP workaround for PEAPv1 session resumption: allow outer, 1372 i.e., not tunneled, EAP-Success to terminate session since; this can 1373 be disabled with eap_workaround=0 1374 13752005-04-25 - v0.4.0 (beginning of 0.4.x development releases) 1376 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be 1377 used to reduce the size of the wpa_supplicant considerably if 1378 debugging code is not needed 1379 * fixed EAPOL-Key validation to drop packets with invalid Key Data 1380 Length; such frames could have crashed wpa_supplicant due to buffer 1381 overflow 1382 * added support for wired authentication (IEEE 802.1X on wired 1383 Ethernet); driver interface 'wired' 1384 * obsoleted set_wpa() handler in the driver interface API (it can be 1385 replaced by moving enable/disable functionality into init()/deinit()) 1386 (calls to set_wpa() are still present for backwards compatibility, 1387 but they may be removed in the future) 1388 * driver_madwifi: fixed association in plaintext mode 1389 * modified the EAP workaround that accepts EAP-Success with incorrect 1390 Identifier to be even less strict about verification in order to 1391 interoperate with some authentication servers 1392 * added support for sending TLS alerts 1393 * added support for 'any' SSID wildcard; if ssid is not configured or 1394 is set to an empty string, any SSID will be accepted for non-WPA AP 1395 * added support for asking PIN (for SIM) from frontends (e.g., 1396 wpa_cli); if a PIN is needed, but not included in the configuration 1397 file, a control interface request is sent and EAP processing is 1398 delayed until the PIN is available 1399 * added support for using external devices (e.g., a smartcard) for 1400 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config); 1401 new wpa_supplicant.conf variables: 1402 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path 1403 - network: engine, engine_id, key_id 1404 * added experimental support for EAP-PAX 1405 * added monitor mode for wpa_cli (-a<path to a program to run>) that 1406 allows external commands (e.g., shell scripts) to be run based on 1407 wpa_supplicant events, e.g., when authentication has been completed 1408 and data connection is ready; other related wpa_cli arguments: 1409 -B (run in background), -P (write PID file); wpa_supplicant has a new 1410 command line argument (-W) that can be used to make it wait until a 1411 control interface command is received in order to avoid missing 1412 events 1413 * added support for opportunistic WPA2 PMKSA key caching (disabled by 1414 default, can be enabled with proactive_key_caching=1) 1415 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where 1416 Authenticator rejects PMKSA caching attempt and the driver is not 1417 using assoc_info events 1418 * added -P<pid file> argument for wpa_supplicant to write the current 1419 process id into a file 1420 14212005-02-12 - v0.3.7 (beginning of 0.3.x stable releases) 1422 * added new phase1 option parameter, include_tls_length=1, to force 1423 wpa_supplicant to add TLS Message Length field to all TLS messages 1424 even if the packet is not fragmented; this may be needed with some 1425 authentication servers 1426 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when 1427 using drivers that take care of AP selection (e.g., when using 1428 ap_scan=2) 1429 * fixed reprocessing of pending request after ctrl_iface requests for 1430 identity/password/otp 1431 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of 1432 EAP-PEAP and EAP-TTLS 1433 * all drivers using driver_wext: set interface up and select Managed 1434 mode when starting wpa_supplicant; set interface down when exiting 1435 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both 1436 ipw2100 and ipw2200; please note that this also changed the 1437 configuration variable in .config to CONFIG_DRIVER_IPW 1438 14392005-01-24 - v0.3.6 1440 * fixed a busy loop introduced in v0.3.5 for scan result processing 1441 when no matching AP is found 1442 14432005-01-23 - v0.3.5 1444 * added a workaround for an interoperability issue with a Cisco AP 1445 when using WPA2-PSK 1446 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as 1447 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow 1448 retransmission of dropped frames) 1449 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version 1450 (e.g., segfault when processing EAPOL-Key frames) 1451 * fixed EAP workaround and fast reauthentication configuration for 1452 RSN pre-authentication; previously these were disabled and 1453 pre-authentication would fail if the used authentication server 1454 requires EAP workarounds 1455 * added support for blacklisting APs that fail or timeout 1456 authentication in ap_scan=1 mode so that all APs are tried in cases 1457 where the ones with strongest signal level are failing authentication 1458 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS 1459 authentication attempt 1460 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded 1461 in the previous authentication (previously, only Phase 1 success was 1462 verified) 1463 14642005-01-09 - v0.3.4 1465 * added preliminary support for IBSS (ad-hoc) mode configuration 1466 (mode=1 in network block); this included a new key_mgmt mode 1467 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no 1468 key management; see wpa_supplicant.conf for more details and an 1469 example on how to configure this (note: this is currently implemented 1470 only for driver_hostapd.c, but the changes should be trivial to add 1471 in associate() handler for other drivers, too (assuming the driver 1472 supports WPA-None) 1473 * added preliminary port for native Windows (i.e., no cygwin) using 1474 mingw 1475 14762005-01-02 - v0.3.3 1477 * added optional support for GNU Readline and History Libraries for 1478 wpa_cli (CONFIG_READLINE) 1479 * cleaned up EAP state machine <-> method interface and number of 1480 small problems with error case processing not terminating on 1481 EAP-Failure but waiting for timeout 1482 * added couple of workarounds for interoperability issues with a 1483 Cisco AP when using WPA2 1484 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt); 1485 Note: This requires a patch for openssl to add support for TLS 1486 extensions and number of workarounds for operations without 1487 certificates. Proof of concept type of experimental patch is 1488 included in openssl-tls-extensions.patch. 1489 14902004-12-19 - v0.3.2 1491 * fixed private key loading for cases where passphrase is not set 1492 * fixed Windows/cygwin L2 packet handler freeing; previous version 1493 could cause a segfault when RSN pre-authentication was completed 1494 * added support for PMKSA caching with drivers that generate RSN IEs 1495 (e.g., NDIS); currently, this is only implemented in driver_ndis.c, 1496 but similar code can be easily added to driver_ndiswrapper.c once 1497 ndiswrapper gets full support for RSN PMKSA caching 1498 * improved recovery from PMKID mismatches by requesting full EAP 1499 authentication in case of failed PMKSA caching attempt 1500 * driver_ndis: added support for NDIS NdisMIncidateStatus() events 1501 (this requires that ndis_events is ran while wpa_supplicant is 1502 running) 1503 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys 1504 * added support for driver interfaces to replace the interface name 1505 based on driver/OS specific mapping, e.g., in case of driver_ndis, 1506 this allows the beginning of the adapter description to be used as 1507 the interface name 1508 * added support for CR+LF (Windows-style) line ends in configuration 1509 file 1510 * driver_ndis: enable radio before starting scanning, disable radio 1511 when exiting 1512 * modified association event handler to set portEnabled = FALSE before 1513 clearing port Valid in order to reset EAP state machine and avoid 1514 problems with new authentication getting ignored because of state 1515 machines ending up in AUTHENTICATED/SUCCESS state based on old 1516 information 1517 * added support for driver events to add PMKID candidates in order to 1518 allow drivers to give priority to most likely roaming candidates 1519 * driver_hostap: moved PrivacyInvoked configuration to associate() 1520 function so that this will not be set for plaintext connections 1521 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver 1522 interface can distinguish plaintext and IEEE 802.1X (no WPA) 1523 authentication 1524 * fixed static WEP key configuration to use broadcast/default type for 1525 all keys (previously, the default TX key was configured as pairwise/ 1526 unicast key) 1527 * driver_ndis: added legacy WPA capability detection for non-WPA2 1528 drivers 1529 * added support for setting static WEP keys for IEEE 802.1X without 1530 dynamic WEP keying (eapol_flags=0) 1531 15322004-12-12 - v0.3.1 1533 * added support for reading PKCS#12 (PFX) files (as a replacement for 1534 PEM/DER) to get certificate and private key (CONFIG_PKCS12) 1535 * fixed compilation with CONFIG_PCSC=y 1536 * added new ap_scan mode, ap_scan=2, for drivers that take care of 1537 association, but need to be configured with security policy and SSID, 1538 e.g., ndiswrapper and NDIS driver; this mode should allow such 1539 drivers to work with hidden SSIDs and optimized roaming; when 1540 ap_scan=2 is used, only the first network block in the configuration 1541 file is used and this configuration should have explicit security 1542 policy (i.e., only one option in the lists) for key_mgmt, pairwise, 1543 group, proto variables 1544 * added experimental port of wpa_supplicant for Windows 1545 - driver_ndis.c driver interface (NDIS OIDs) 1546 - currently, this requires cygwin and WinPcap 1547 - small utility, win_if_list, can be used to get interface name 1548 * control interface can now be removed at build time; add 1549 CONFIG_CTRL_IFACE=y to .config to maintain old functionality 1550 * optional Xsupplicant interface can now be removed at build time; 1551 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back) 1552 * added auth_alg to driver interface associate() parameters to make it 1553 easier for drivers to configure authentication algorithm as part of 1554 the association 1555 15562004-12-05 - v0.3.0 (beginning of 0.3.x development releases) 1557 * driver_broadcom: added new driver interface for Broadcom wl.o driver 1558 (a generic driver for Broadcom IEEE 802.11a/g cards) 1559 * wpa_cli: fixed parsing of -p <path> command line argument 1560 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS 1561 ACK, not tunneled EAP-Success (of which only the first byte was 1562 actually send due to a bug in previous code); this seems to 1563 interoperate with most RADIUS servers that implements PEAPv1 1564 * PEAPv1: added support for terminating PEAP authentication on tunneled 1565 EAP-Success message; this can be configured by adding 1566 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf 1567 (some RADIUS servers require this whereas others require a tunneled 1568 reply 1569 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to 1570 the old label for key derivation; previously, the default was 1, 1571 but it looks like most existing PEAPv1 implementations use the old 1572 label which is thus more suitable default option 1573 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt) 1574 * fixed parsing of wep_tx_keyidx 1575 * added support for configuring list of allowed Phase 2 EAP types 1576 (for both EAP-PEAP and EAP-TTLS) instead of only one type 1577 * added support for configuring IEEE 802.11 authentication algorithm 1578 (auth_alg; mainly for using Shared Key authentication with static 1579 WEP keys) 1580 * added support for EAP-AKA (with UMTS SIM) 1581 * fixed couple of errors in PCSC handling that could have caused 1582 random-looking errors for EAP-SIM 1583 * added support for EAP-SIM pseudonyms and fast re-authentication 1584 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS 1585 session resumption) 1586 * added support for EAP-SIM with two challanges 1587 (phase1="sim_min_num_chal=3" can be used to require three challenges) 1588 * added support for configuring DH/DSA parameters for an ephemeral DH 1589 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters 1590 dh_file and dh_file2 (phase 2); this adds support for using DSA keys 1591 and optional DH key exchange to achieve forward secracy with RSA keys 1592 * added support for matching subject of the authentication server 1593 certificate with a substring when using EAP-TLS/PEAP/TTLS; new 1594 configuration variables subject_match and subject_match2 1595 * changed SSID configuration in driver_wext.c (used by many driver 1596 interfaces) to use ssid_len+1 as the length for SSID since some Linux 1597 drivers expect this 1598 * fixed couple of unaligned reads in scan result parsing to fix WPA 1599 connection on some platforms (e.g., ARM) 1600 * added driver interface for Intel ipw2100 driver 1601 * added support for LEAP with WPA 1602 * added support for larger scan results report (old limit was 4 kB of 1603 data, i.e., about 35 or so APs) when using Linux wireless extensions 1604 v17 or newer 1605 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start 1606 only if there is a PMKSA cache entry for the current AP 1607 * fixed error handling for case where reading of scan results fails: 1608 must schedule a new scan or wpa_supplicant will remain waiting 1609 forever 1610 * changed debug output to remove shared password/key material by 1611 default; all key information can be included with -K command line 1612 argument to match the previous behavior 1613 * added support for timestamping debug log messages (disabled by 1614 default, can be enabled with -t command line argument) 1615 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104 1616 if keys are not configured to be used; this fixes IEEE 802.1X mode 1617 with drivers that use this information to configure whether Privacy 1618 bit can be in Beacon frames (e.g., ndiswrapper) 1619 * avoid clearing driver keys if no keys have been configured since last 1620 key clear request; this seems to improve reliability of group key 1621 handshake for ndiswrapper & NDIS driver which seems to be suffering 1622 of some kind of timing issue when the keys are cleared again after 1623 association 1624 * changed driver interface API: 1625 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which 1626 version is being used (now, this is set to 2; previously, it was 1627 not defined) 1628 - pass pointer to private data structure to all calls 1629 - the new API is not backwards compatible; all in-tree driver 1630 interfaces has been converted to the new API 1631 * added support for controlling multiple interfaces (radios) per 1632 wpa_supplicant process; each interface needs to be listed on the 1633 command line (-c, -i, -D arguments) with -N as a separator 1634 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi) 1635 * added a workaround for EAP servers that incorrectly use same Id for 1636 sequential EAP packets 1637 * changed libpcap/libdnet configuration to use .config variable, 1638 CONFIG_DNET_PCAP, instead of requiring Makefile modification 1639 * improved downgrade attack detection in IE verification of msg 3/4: 1640 verify both WPA and RSN IEs, if present, not only the selected one; 1641 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or 1642 Probe Response frame, and RSN is enabled in wpa_supplicant 1643 configuration 1644 * fixed WPA msg 3/4 processing to allow Key Data field contain other 1645 IEs than just one WPA IE 1646 * added support for FreeBSD and driver interface for the BSD net80211 1647 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the 1648 required kernel mods have not yet been committed 1649 * made EAP workarounds configurable; enabled by default, can be 1650 disabled with network block option eap_workaround=0 1651 16522004-07-17 - v0.2.4 (beginning of 0.2.x stable releases) 1653 * resolved couple of interoperability issues with EAP-PEAPv1 and 1654 Phase 2 (inner EAP) fragment reassembly 1655 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the 1656 AP is using non-zero key index for the unicast key and key index zero 1657 for the broadcast key 1658 * driver_hostap: fixed IEEE 802.1X WEP key updates and 1659 re-authentication by allowing unencrypted EAPOL frames when not using 1660 WPA 1661 * added a new driver interface, 'wext', which uses only standard, 1662 driver independent functionality in Linux wireless extensions; 1663 currently, this can be used only for non-WPA IEEE 802.1X mode, but 1664 eventually, this is to be extended to support full WPA/WPA2 once 1665 Linux wireless extensions get support for this 1666 * added support for mode in which the driver is responsible for AP 1667 scanning and selection; this is disabled by default and can be 1668 enabled with global ap_scan=0 variable in wpa_supplicant.conf; 1669 this mode can be used, e.g., with generic 'wext' driver interface to 1670 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver 1671 supporting wireless extensions. 1672 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g., 1673 operation with an AP that does not include SSID in the Beacon frames) 1674 * added support for new EAP authentication methods: 1675 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP 1676 * added support for asking one-time-passwords from frontends (e.g., 1677 wpa_cli); this 'otp' command works otherwise like 'password' command, 1678 but the password is used only once and the frontend will be asked for 1679 a new password whenever a request from authenticator requires a 1680 password; this can be used with both EAP-OTP and EAP-GTC 1681 * changed wpa_cli to automatically re-establish connection so that it 1682 does not need to be re-started when wpa_supplicant is terminated and 1683 started again 1684 * improved user data (identity/password/otp) requests through 1685 frontends: process pending EAPOL packets after getting new 1686 information so that full authentication does not need to be 1687 restarted; in addition, send pending requests again whenever a new 1688 frontend is attached 1689 * changed control frontends to use a new directory for socket files to 1690 make it easier for wpa_cli to automatically select between interfaces 1691 and to provide access control for the control interface; 1692 wpa_supplicant.conf: ctrl_interface is now a path 1693 (/var/run/wpa_supplicant is the recommended path) and 1694 ctrl_interface_group can be used to select which group gets access to 1695 the control interface; 1696 wpa_cli: by default, try to connect to the first interface available 1697 in /var/run/wpa_supplicant; this path can be overriden with -p option 1698 and an interface can be selected with -i option (i.e., in most common 1699 cases, wpa_cli does not need to get any arguments) 1700 * added support for LEAP 1701 * added driver interface for Linux ndiswrapper 1702 * added priority option for network blocks in the configuration file; 1703 this allows networks to be grouped based on priority (the scan 1704 results are searched for matches with network blocks in this order) 1705 17062004-06-20 - v0.2.3 1707 * sort scan results to improve AP selection 1708 * fixed control interface socket removal for some error cases 1709 * improved scan requesting and authentication timeout 1710 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and 1711 TLS processing 1712 * PEAP version can now be forced with phase1="peapver=<ver>" 1713 (mostly for testing; by default, the highest version supported by 1714 both the Supplicant and Authentication Server is selected 1715 automatically) 1716 * added support for madwifi driver (Atheros ar521x) 1717 * added a workaround for cases where AP sets Install Tx/Rx bit for 1718 WPA Group Key messages when pairwise keys are used (without this, 1719 the Group Key would be used for Tx and the AP would drop frames 1720 from the station) 1721 * added GSM SIM/USIM interface for GSM authentication algorithm for 1722 EAP-SIM; this requires pcsc-lite 1723 * added support for ATMEL AT76C5XXx driver 1724 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator 1725 does not include key data in the EAPOL-Key frame (i.e., part of 1726 EAP keying material is used as data encryption key) 1727 * added support for using plaintext and static WEP networks 1728 (key_mgmt=NONE) 1729 17302004-05-31 - v0.2.2 1731 * added support for new EAP authentication methods: 1732 EAP-TTLS/EAP-MD5-Challenge 1733 EAP-TTLS/EAP-GTC 1734 EAP-TTLS/EAP-MSCHAPv2 1735 EAP-TTLS/EAP-TLS 1736 EAP-TTLS/MSCHAPv2 1737 EAP-TTLS/MSCHAP 1738 EAP-TTLS/PAP 1739 EAP-TTLS/CHAP 1740 EAP-PEAP/TLS 1741 EAP-PEAP/GTC 1742 EAP-PEAP/MD5-Challenge 1743 EAP-GTC 1744 EAP-SIM (not yet complete; needs GSM/SIM authentication interface) 1745 * added support for anonymous identity (to be used when identity is 1746 sent in plaintext; real identity will be used within TLS protected 1747 tunnel (e.g., with EAP-TTLS) 1748 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli 1749 * added support for requesting identity and password information using 1750 control interface; in other words, the password for EAP-PEAP or 1751 EAP-TTLS does not need to be included in the configuration file since 1752 a frontand (e.g., wpa_cli) can ask it from the user 1753 * improved RSN pre-authentication to use a candidate list and process 1754 all candidates from each scan; not only one per scan 1755 * fixed RSN IE and WPA IE capabilities field parsing 1756 * ignore Tx bit in GTK IE when Pairwise keys are used 1757 * avoid making new scan requests during IEEE 802.1X negotiation 1758 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant 1759 with TLS support (this replaces the included implementation with 1760 library code to save about 8 kB since the library code is needed 1761 anyway for TLS) 1762 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support 1763 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config) 1764 17652004-05-06 - v0.2.1 1766 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1) 1767 Supplicant 1768 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1] 1769 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf] 1770 - EAP-MD5 (cannot be used with WPA-RADIUS) 1771 [draft-ietf-eap-rfc2284bis-09.txt] 1772 - EAP-TLS [RFC 2716] 1773 - EAP-MSCHAPv2 (currently used only with EAP-PEAP) 1774 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt] 1775 [draft-kamath-pppext-eap-mschapv2-00.txt] 1776 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by 1777 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey) 1778 - new configuration file options: eap, identity, password, ca_cert, 1779 client_cert, privatekey, private_key_passwd 1780 - Xsupplicant is not required anymore, but it can be used by 1781 disabling the internal IEEE 802.1X Supplicant with -e command line 1782 option 1783 - this code is not included in the default build; Makefile need to 1784 be edited for this (uncomment lines for selected functionality) 1785 - EAP-TLS and EAP-PEAP require openssl libraries 1786 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..) 1787 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys 1788 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X 1789 EAPOL-Key frames instead of WPA key handshakes) 1790 * added support for IEEE 802.11i/RSN (WPA2) 1791 - improved PTK Key Handshake 1792 - PMKSA caching, pre-authentication 1793 * fixed wpa_supplicant to ignore possible extra data after WPA 1794 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using 1795 TPTK' error from message 3 of 4-Way Handshake in case the AP 1796 includes extra data after the EAPOL-Key) 1797 * added interface for external programs (frontends) to control 1798 wpa_supplicant 1799 - CLI example (wpa_cli) with interactive mode and command line 1800 mode 1801 - replaced SIGUSR1 status/statistics with the new control interface 1802 * made some feature compile time configurable 1803 - .config file for make 1804 - driver interfaces (hostap, hermes, ..) 1805 - EAPOL/EAP functions 1806 18072004-02-15 - v0.2.0 1808 * Initial version of wpa_supplicant 1809
