a new command line parameter -u can be used to enable updating of 567 SQN in Milenage file 568 - use 5 bit IND for SQN updates 569 - SQLite database can now be used to store Milenage information 570 * EAP-SIM/AKA DB: added optional use of SQLite database for pseudonyms 571 and reauth data 572 * added support for Chargeable-User-Identity (RFC 4372) 573 * added radius_auth_req_attr and radius_acct_req_attr configuration 574 parameters to allow adding/overriding of RADIUS attributes in 575 Access-Request and Accounting-Request packets 576 * added support for RADIUS dynamic authorization server (RFC 5176) 577 * added initial support for WNM operations 578 - BSS max idle period 579 - WNM-Sleep Mode 580 * added new WPS NFC ctrl_iface mechanism 581 - removed obsoleted WPS_OOB command (including support for deprecated 582 UFD config_method) 583 * added FT support for drivers that implement MLME internally 584 * added SA Query support for drivers that implement MLME internally 585 * removed default ACM=1 from AC_VO and AC_VI 586 * changed VENDOR-TEST EAP method to use proper private enterprise number 587 (this will not interoperate with older versions) 588 * added hostapd.conf parameter vendor_elements to allow arbitrary vendor 589 specific elements to be added to the Beacon and Probe Response frames 590 * added support for configuring GCMP cipher for IEEE 802.11ad 591 * added support for 256-bit AES with internal TLS implementation 592 * changed EAPOL transmission to use AC_VO if WMM is active 593 * fixed EAP-TLS/PEAP/TTLS/FAST server to validate TLS Message Length 594 correctly; invalid messages could have caused the hostapd process to 595 terminate before this fix [CVE-2012-4445] 596 * limit number of active wildcard PINs for WPS Registrar to one to avoid 597 confusing behavior with multiple wildcard PINs 598 * added a workaround for WPS PBC session overlap detection to avoid 599 interop issues with deployed station implementations that do not 600 remove active PBC indication from Probe Request frames properly 601 * added support for using SQLite for the eap_user database 602 * added Acct-Session-Id attribute into Access-Request messages 603 * fixed EAPOL frame transmission to non-QoS STAs with nl80211 604 (do not send QoS frames if the STA did not negotiate use of QoS for 605 this association) 606 6072012-05-10 - v1.0 608 * Add channel selection support in hostapd. See hostapd.conf. 609 * Add support for IEEE 802.11v Time Advertisement mechanism with UTC 610 TSF offset. See hostapd.conf for config info. 611 * Delay STA entry removal until Deauth/Disassoc TX status in AP mode. 612 This allows the driver to use PS buffering of Deauthentication and 613 Disassociation frames when the STA is in power save sleep. Only 614 available with drivers that provide TX status events for Deauth/ 615 Disassoc frames (nl80211). 616 * Allow PMKSA caching to be disabled on the Authenticator. See 617 hostap.conf config parameter disable_pmksa_caching. 618 * atheros: Add support for IEEE 802.11w configuration. 619 * bsd: Add support for setting HT values in IFM_MMASK. 620 * Allow client isolation to be configured with ap_isolate. Client 621 isolation can be used to prevent low-level bridging of frames 622 between associated stations in the BSS. By default, this bridging 623 is allowed. 624 * Allow coexistance of HT BSSes with WEP/TKIP BSSes. 625 * Add require_ht config parameter, which can be used to configure 626 hostapd to reject association with any station that does not support 627 HT PHY. 628 * Add support for writing debug log to a file using "-f" option. Also 629 add relog CLI command to re-open the log file. 630 * Add bridge handling for WDS STA interfaces. By default they are 631 added to the configured bridge of the AP interface (if present), 632 but the user can also specify a separate bridge using cli command 633 wds_bridge. 634 * hostapd_cli: 635 - Add wds_bridge command for specifying bridge for WDS STA 636 interfaces. 637 - Add relog command for reopening log file. 638 - Send AP-STA-DISCONNECTED event when an AP disconnects a station 639 due to inactivity. 640 - Add wps_config ctrl_interface command for configuring AP. This 641 command can be used to configure the AP using the internal WPS 642 registrar. It works in the same way as new AP settings received 643 from an ER. 644 - Many WPS/WPS ER commands - see WPS/WPS ER sections for details. 645 - Add command get version, that returns hostapd version string. 646 * WNM: Add BSS Transition Management Request for ESS Disassoc Imminent. 647 Use hostapd_cli ess_disassoc (STA addr) (URL) to send the 648 notification to the STA. 649 * Allow AP mode to disconnect STAs based on low ACK condition (when 650 the data connection is not working properly, e.g., due to the STA 651 going outside the range of the AP). Disabled by default, enable by 652 config option disassoc_low_ack. 653 * Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad 654 config file. 655 * WPS: 656 - Send AP Settings as a wrapped Credential attribute to ctrl_iface 657 in WPS-NEW-AP-SETTINGS. 658 - Dispatch more WPS events through hostapd ctrl_iface. 659 - Add mechanism for indicating non-standard WPS errors. 660 - Change concurrent radio AP to use only one WPS UPnP instance. 661 - Add wps_check_pin command for processing PIN from user input. 662 UIs can use this command to process a PIN entered by a user and to 663 validate the checksum digit (if present). 664 - Add hostap_cli get_config command to display current AP config. 665 - Add new hostapd_cli command, wps_ap_pin, to manage AP PIN at 666 runtime and support dynamic AP PIN management. 667 - Disable AP PIN after 10 consecutive failures. Slow down attacks 668 on failures up to 10. 669 - Allow AP to start in Enrollee mode without AP PIN for probing, 670 to be compatible with Windows 7. 671 - Add Config Error into WPS-FAIL events to provide more info 672 to the user on how to resolve the issue. 673 - When controlling multiple interfaces: 674 - apply WPS commands to all interfaces configured to use WPS 675 - apply WPS config changes to all interfaces that use WPS 676 - when an attack is detected on any interface, disable AP PIN on 677 all interfaces 678 * WPS ER: 679 - Show SetSelectedRegistrar events as ctrl_iface events. 680 - Add special AP Setup Locked mode to allow read only ER. 681 ap_setup_locked=2 can now be used to enable a special mode where 682 WPS ER can learn the current AP settings, but cannot change them. 683 * WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2) 684 - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool 685 for testing protocol extensibility. 686 - Add build option CONFIG_WPS_STRICT to allow disabling of WPS 687 workarounds. 688 - Add support for AuthorizedMACs attribute. 689 * TDLS: 690 - Allow TDLS use or TDLS channel switching in the BSS to be 691 prohibited in the BSS, using config params tdls_prohibit and 692 tdls_prohibit_chan_switch. 693 * EAP server: Add support for configuring fragment size (see 694 fragment_size in hostapd.conf). 695 * wlantest: Add a tool wlantest for IEEE802.11 protocol testing. 696 wlantest can be used to capture frames from a monitor interface 697 for realtime capturing or from pcap files for offline analysis. 698 * Interworking: Support added for 802.11u. Enable in .config with 699 CONFIG_INTERWORKING. See hostapd.conf for config parameters for 700 interworking. 701 * Android: Add build and runtime support for Android hostapd. 702 * Add a new debug message level for excessive information. Use 703 -ddd to enable. 704 * TLS: Add support for tls_disable_time_checks=1 in client mode. 705 * Internal TLS: 706 - Add support for TLS v1.1 (RFC 4346). Enable with build parameter 707 CONFIG_TLSV11. 708 - Add domainComponent parser for X.509 names 709 * Reorder some IEs to get closer to IEEE 802.11 standard. Move 710 WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames. 711 Move HT IEs to be later in (Re)Assoc Resp. 712 * Many bugfixes. 713 7142010-04-18 - v0.7.2 715 * fix WPS internal Registrar use when an external Registrar is also 716 active 717 * bsd: Cleaned up driver wrapper and added various low-level 718 configuration options 719 * TNC: fixed issues with fragmentation 720 * EAP-TNC: add Flags field into fragment acknowledgement (needed to 721 interoperate with other implementations; may potentially breaks 722 compatibility with older wpa_supplicant/hostapd versions) 723 * cleaned up driver wrapper API for multi-BSS operations 724 * nl80211: fix multi-BSS and VLAN operations 725 * fix number of issues with IEEE 802.11r/FT;

the new API 743 is not fully backwards compatible, so out-of-tree driver wrappers 744 will need modifications 745 * cleaned up various module interfaces 746 * merge hostapd and wpa_supplicant developers' documentation into a 747 single document 748 * fixed HT Capabilities IE with nl80211 drivers 749 * moved generic AP functionality code into src/ap 750 * WPS: handle Selected Registrar as union of info from all Registrars 751 * remove obsolete Prism54.org driver wrapper 752 * added internal debugging mechanism with backtrace support and memory 753 allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y) 754 * EAP-FAST server: piggyback Phase 2 start with the end of Phase 1 755 * WPS: add support for dynamically selecting whether to provision the 756 PSK as an ASCII passphrase or PSK 757 * added support for WDS (4-address frame) mode with per-station virtual 758 interfaces (wds_sta=1 in config file; only supported with 759 driver=nl80211 for now) 760 * fixed WPS Probe Request processing to handle missing required 761 attribute 762 * fixed PKCS#12 use with OpenSSL 1.0.0 763 * detect bridge interface automatically so that bridge parameter in 764 hostapd.conf becomes optional (though, it may now be used to 765 automatically add then WLAN interface into a bridge with 766 driver=nl80211) 767 7682009-11-21 - v0.7.0 769 * increased hostapd_cli ping interval to 5 seconds and made this 770 configurable with a new command line options (-G<seconds>) 771 * driver_nl80211: use Linux socket filter to improve performance 772 * added support for external Registrars with WPS (UPnP transport) 773 * 802.11n: scan for overlapping BSSes before starting 20/40 MHz channel 774 * driver_nl80211: fixed STA accounting data collection (TX/RX bytes 775 reported correctly; TX/RX packets not yet available from kernel) 776 * added support for WPS USBA out-of-band mechanism with USB Flash 777 Drives (UFD) (CONFIG_WPS_UFD=y) 778 * fixed EAPOL/EAP reauthentication when using an external RADIUS 779 authentication server 780 * fixed TNC with EAP-TTLS 781 * fixed IEEE 802.11r key derivation function to match with the standard 782 (note: this breaks interoperability with previous version) [Bug 303] 783 * fixed SHA-256 based key derivation function to match with the 784 standard when using CCMP (for IEEE 802.11r and IEEE 802.11w) 785 (note: this breaks interoperability with previous version) [Bug 307] 786 * added number of code size optimizations to remove unnecessary 787 functionality from the program binary based on build configuration 788 (part of this automatic; part configurable with CONFIG_NO_* build 789 options) 790 * use shared driver wrapper files with wpa_supplicant 791 * driver_nl80211: multiple updates to provide support for new Linux 792 nl80211/mac80211 functionality 793 * updated management frame protection to use IEEE Std 802.11w-2009 794 * fixed number of small WPS issues and added workarounds to 795 interoperate with common deployed broken implementations 796 * added some IEEE 802.11n co-existence rules to disable 40 MHz channels 797 or modify primary/secondary channels if needed based on neighboring 798 networks 799 * added support for NFC out-of-band mechanism with WPS 800 * added preliminary support for IEEE 802.11r RIC processing 801 8022009-01-06 - v0.6.7 803 * added support for Wi-Fi Protected Setup (WPS) 804 (hostapd can now be configured to act as an integrated WPS Registrar 805 and provision credentials for WPS Enrollees using PIN and PBC 806 methods; external wireless Registrar can configure the AP, but 807 external WLAN Manager Registrars are not supported); WPS support can 808 be enabled by adding CONFIG_WPS=y into .config and setting the 809 runtime configuration variables in hostapd.conf (see WPS section in 810 the example configuration file); new hostapd_cli commands wps_pin and 811 wps_pbc are used to configure WPS negotiation; see README-WPS for 812 more details 813 * added IEEE 802.11n HT capability configuration (ht_capab) 814 * added support for generating Country IE based on nl80211 regulatory 815 information (added if ieee80211d=1 in configuration) 816 * fixed WEP authentication (both Open System and Shared Key) with 817 mac80211 818 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf) 819 * added support for using driver_test over UDP socket 820 * changed EAP-GPSK to use the IANA assigned EAP method type 51 821 * updated management frame protection to use IEEE 802.11w/D7.0 822 * fixed retransmission of EAP requests if no response is received 823 8242008-11-23 - v0.6.6 825 * added a new configuration option, wpa_ptk_rekey, that can be used to 826 enforce frequent PTK rekeying, e.g., to mitigate some attacks against 827 TKIP deficiencies 828 * updated OpenSSL code for EAP-FAST to use an updated version of the 829 session ticket overriding API that was included into the upstream 830 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is 831 needed with that version anymore) 832 * changed channel flags configuration to read the information from 833 the driver (e.g., via driver_nl80211 when using mac80211) instead of 834 using hostapd as the source of the regulatory information (i.e., 835 information from CRDA is now used with mac80211); this allows 5 GHz 836 channels to be used with hostapd (if allowed in the current 837 regulatory domain) 838 * fixed EAP-TLS message processing for the last TLS message if it is 839 large enough to require fragmentation (e.g., if a large Session 840 Ticket data is included) 841 * fixed listen interval configuration for nl80211 drivers 842 8432008-11-01 - v0.6.5 844 * added support for SHA-256 as X.509 certificate digest when using the 845 internal X.509/TLSv1 implementation 846 * fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer 847 identity lengths) 848 * fixed internal TLSv1 implementation for abbreviated handshake (used 849 by EAP-FAST server) 850 * added support for setting VLAN ID for STAs based on local MAC ACL 851 (accept_mac_file) as an alternative for RADIUS server-based 852 configuration 853 * updated management frame protection to use IEEE 802.11w/D6.0 854 (adds a new association ping to protect against unauthenticated 855 authenticate or (re)associate request frames dropping association) 856 * added support for using SHA256-based stronger key derivation for WPA2 857 (IEEE 802.11w) 858 * added new "driver wrapper" for RADIUS-only configuration 859 (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config) 860 * fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2) 861 is enabled in configuration 862 * changed EAP-FAST configuration to use separate fields for A-ID and 863 A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed 864 16-octet len binary value for better interoperability with some peer 865 implementations; eap_fast_a_id is now configured as a hex string 866 * driver_nl80211: Updated to match the current Linux mac80211 AP mode 867 configuration (wireless-testing.git and Linux kernel releases 868 starting from 2.6.29) 869 8702008-08-10 - v0.6.4 871 * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2 872 Identity Request if identity is already known 873 * added support for EAP Sequences in EAP-FAST Phase 2 874 * added support for EAP-TNC (Trusted Network Connect) 875 (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST 876 changes needed to run two methods in sequence (IF-T) and the IF-IMV 877 and IF-TNCCS interfaces from TNCS) 878 * added support for optional cryptobinding with PEAPv0 879 * added fragmentation support for EAP-TNC 880 * added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled) 881 data 882 * added support for opportunistic key caching (OKC) 883 8842008-02-22 - v0.6.3 885 * fixed Reassociation Response callback processing when using internal 886 MLME (driver_{hostap,nl80211,test}.c) 887 * updated FT support to use the latest draft, IEEE 802.11r/D9.0 888 * copy optional Proxy-State attributes into RADIUS response when acting 889 as a RADIUS authentication server 890 * fixed EAPOL state machine to handle a case in which no response is 891 received from the RADIUS authentication server; previous version 892 could have triggered a crash in some cases after a timeout 893 * fixed EAP-SIM/AKA realm processing to allow decorated usernames to 894 be used 895 * added a workaround for EAP-SIM/AKA peers that include incorrect null 896 termination in the username 897 * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER 898 attribute in notification messages only when using fast 899 reauthentication 900 * fixed EAP-SIM Start response processing for fast reauthentication 901 case 902 * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST} 903 phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method 904 9052008-01-01 - v0.6.2 906 * fixed EAP-SIM and EAP-AKA message parser to validate attribute 907 lengths properly to avoid potential crash caused by invalid messages 908 * added data structure for storing allocated buffers (struct wpabuf); 909 this does not affect hostapd usage, but many of the APIs changed 910 and various interfaces (e.g., EAP) is not compatible with old 911 versions 912 * added support for protecting EAP-AKA/Identity messages with 913 AT_CHECKCODE (optional feature in RFC 4187) 914 * added support for protected result indication with AT_RESULT_IND for 915 EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1) 916 * added support for configuring EAP-TTLS phase 2 non-EAP methods in 917 EAP server configuration; previously all four were enabled for every 918 phase 2 user, now all four are disabled by default and need to be 919 enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP, 920 TTLS-MSCHAPV2 921 * removed old debug printing mechanism and the related 'debug' 922 parameter in the configuration file; debug verbosity is now set with 923 -d (or -dd) command line arguments 924 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt); 925 only shared key/password authentication is supported in this version 926 9272007-11-24 - v0.6.1 928 * added experimental, integrated TLSv1 server implementation with the 929 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by 930 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in 931 .config); this can be useful, e.g., if the target system does not 932 have a suitable TLS library and a minimal code size is required 933 * added support for EAP-FAST server method to the integrated EAP 934 server 935 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 936 draft (draft-ietf-emu-eap-gpsk-07.txt) 937 * added a new configuration parameter, rsn_pairwise, to allow different 938 pairwise cipher suites to be enabled for WPA and RSN/WPA2 939 (note: if wpa_pairwise differs from rsn_pairwise, the driver will 940 either need to support this or will have to use the WPA/RSN IEs from 941 hostapd; currently, the included madwifi and bsd driver interfaces do 942 not have support for this) 943 * updated FT support to use the latest draft, IEEE 802.11r/D8.0 944 9452007-05-28 - v0.6.0 946 * added experimental IEEE 802.11r/D6.0 support 947 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48 948 * updated EAP-PSK to use the IANA-allocated EAP type 47 949 * fixed EAP-PSK bit ordering of the Flags field 950 * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs 951 by reading wpa_psk_file [Bug 181] 952 * fixed EAP-TTLS AVP parser processing for too short AVP lengths 953 * fixed IPv6 connection to RADIUS accounting server 954 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 955 draft (draft-ietf-emu-eap-gpsk-04.txt) 956 * hlr_auc_gw: read GSM triplet file into memory and rotate through the 957 entries instead of only using the same three triplets every time 958 (this does not work properly with tests using multiple clients, but 959 provides bit better triplet data for testing a single client; anyway, 960 if a better quality triplets are needed, GSM-Milenage should be used 961 instead of hardcoded triplet file) 962 * fixed EAP-MSCHAPv2 server to use a space between S and M parameters 963 in Success Request [Bug 203] 964 * added support for sending EAP-AKA Notifications in error cases 965 * updated to use IEEE 802.11w/D2.0 for management frame protection 966 (still experimental) 967 * RADIUS server: added support for processing duplicate messages 968 (retransmissions from RADIUS client) by replying with the previous 969 reply 970 9712006-11-24 - v0.5.6 972 * added support for configuring and controlling multiple BSSes per 973 radio interface (bss=<ifname> in hostapd.conf); this is only 974 available with Devicescape and test driver interfaces 975 * fixed PMKSA cache update in the end of successful RSN 976 pre-authentication 977 * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID 978 for each STA based on RADIUS Access-Accept attributes); this requires 979 VLAN support from the kernel driver/802.11 stack and this is 980 currently only available with Devicescape and test driver interfaces 981 * driver_madwifi: fixed configuration of unencrypted modes (plaintext 982 and IEEE 802.1X without WEP) 983 * removed STAKey handshake since PeerKey handshake has replaced it in 984 IEEE 802.11ma and there are no known deployments of STAKey 985 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 986 draft (draft-ietf-emu-eap-gpsk-01.txt) 987 * added preliminary implementation of IEEE 802.11w/D1.0 (management 988 frame protection) 989 (Note: this requires driver support to work properly.) 990 (Note2: IEEE 802.11w is an unapproved draft and subject to change.) 991 * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM) 992 * hlr_auc_gw: added support for reading per-IMSI Milenage keys and 993 parameters from a text file to make it possible to implement proper 994 GSM/UMTS authentication server for multiple SIM/USIM cards using 995 EAP-SIM/EAP-AKA 996 * fixed session timeout processing with drivers that do not use 997 ieee802_11.c (e.g., madwifi) 998 9992006-08-27 - v0.5.5 1000 * added 'hostapd_cli new_sta <addr>' command for adding a new STA into 1001 hostapd (e.g., to initialize wired network authentication based on an 1002 external signal) 1003 * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when 1004 using WPA2 even if PMKSA caching is not used 1005 * added -P<pid file> argument for hostapd to write the current process 1006 id into a file 1007 * added support for RADIUS Authentication Server MIB (RFC 2619) 1008 10092006-06-20 - v0.5.4 1010 * fixed nt_password_hash build [Bug 144] 1011 * added PeerKey handshake implementation for IEEE 802.11e 1012 direct link setup (DLS) to replace STAKey handshake 1013 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK, 1014 draft-clancy-emu-eap-shared-secret-00.txt) 1015 * fixed a segmentation fault when RSN pre-authentication was completed 1016 successfully [Bug 152] 1017 10182006-04-27 - v0.5.3 1019 * do not build nt_password_hash and hlr_auc_gw by default to avoid 1020 requiring a TLS library for a successful build; these programs can be 1021 build with 'make nt_password_hash' and 'make hlr_auc_gw' 1022 * added a new configuration option, eapol_version, that can be used to 1023 set EAPOL version to 1 (default is 2) to work around broken client 1024 implementations that drop EAPOL frames which use version number 2 1025 [Bug 89] 1026 * added support for EAP-SAKE (no EAP method number allocated yet, so 1027 this is using the same experimental type 255 as EAP-PSK) 1028 * fixed EAP-MSCHAPv2 message length validation 1029 10302006-03-19 - v0.5.2 1031 * fixed stdarg use in hostapd_logger(): if both stdout and syslog 1032 logging was enabled, hostapd could trigger a segmentation fault in 1033 vsyslog on some CPU -- C library combinations 1034 * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external 1035 program to make it easier to use for implementing real SS7 gateway; 1036 eap_sim_db is not anymore used as a file name for GSM authentication 1037 triplets; instead, it is path to UNIX domain socket that will be used 1038 to communicate with the external gateway program (e.g., hlr_auc_gw) 1039 * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses 1040 local information (GSM authentication triplets from a text file and 1041 hardcoded AKA authentication data); this can be used to test EAP-SIM 1042 and EAP-AKA 1043 * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw 1044 to make it possible to test EAP-AKA with real USIM cards (this is 1045 disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw 1046 to enable this) 1047 * driver_madwifi: added support for getting station RSN IE from 1048 madwifi-ng svn r1453 and newer; this fixes RSN that was apparently 1049 broken with earlier change (r1357) in the driver 1050 * changed EAP method registration to use a dynamic list of methods 1051 instead of a static list generated at build time 1052 * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE) 1053 [Bug 125] 1054 * added ap_max_inactivity configuration parameter 1055 10562006-01-29 - v0.5.1 1057 * driver_test: added better support for multiple APs and STAs by using 1058 a directory with sockets that include MAC address for each device in 1059 the name (test_socket=DIR:/tmp/test) 1060 * added support for EAP expanded type (vendor specific EAP methods) 1061 10622005-12-18 - v0.5.0 (beginning of 0.5.x development releases) 1063 * added experimental STAKey handshake implementation for IEEE 802.11e 1064 direct link setup (DLS); note: this is disabled by default in both 1065 build and runtime configuration (can be enabled with CONFIG_STAKEY=y 1066 and stakey=1) 1067 * added support for EAP methods to use callbacks to external programs 1068 by buffering a pending request and processing it after the EAP method 1069 is ready to continue 1070 * improved EAP-SIM database interface to allow external request to GSM 1071 HLR/AuC without blocking hostapd process 1072 * added support for using EAP-SIM pseudonyms and fast re-authentication 1073 * added support for EAP-AKA in the integrated EAP authenticator 1074 * added support for matching EAP identity prefixes (e.g., "1"*) in EAP 1075 user database to allow EAP-SIM/AKA selection without extra roundtrip 1076 for EAP-Nak negotiation 1077 * added support for storing EAP user password as NtPasswordHash instead 1078 of plaintext password when using MSCHAP or MSCHAPv2 for 1079 authentication (hash:<16-octet hex value>); added nt_password_hash 1080 tool for hashing password to generate NtPasswordHash 1081 10822005-11-20 - v0.4.7 (beginning of 0.4.x stable releases) 1083 * driver_wired: fixed EAPOL sending to optionally use PAE group address 1084 as the destination instead of supplicant MAC address; this is 1085 disabled by default, but should be enabled with use_pae_group_addr=1 1086 in configuration file if the wired interface is used by only one 1087 device at the time (common switch configuration) 1088 * driver_madwifi: configure driver to use TKIP countermeasures in order 1089 to get correct behavior (IEEE 802.11 association failing; previously, 1090 association succeeded, but hostpad forced disassociation immediately) 1091 * driver_madwifi: added support for madwifi-ng 1092 10932005-10-27 - v0.4.6 1094 * added support for replacing user identity from EAP with RADIUS 1095 User-Name attribute from Access-Accept message, if that is included, 1096 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get 1097 tunneled identity into accounting messages when the RADIUS server 1098 does not support better way of doing this with Class attribute) 1099 * driver_madwifi: fixed EAPOL packet receive for configuration where 1100 ath# is part of a bridge interface 1101 * added a configuration file and log analyzer script for logwatch 1102 * fixed EAPOL state machine step function to process all state 1103 transitions before processing new events; this resolves a race 1104 condition in which EAPOL-Start message could trigger hostapd to send 1105 two EAP-Response/Identity frames to the authentication server 1106 11072005-09-25 - v0.4.5 1108 * added client CA list to the TLS certificate request in order to make 1109 it easier for the client to select which certificate to use 1110 * added experimental support for EAP-PSK 1111 * added support for WE-19 (hostap, madwifi) 1112 11132005-08-21 - v0.4.4 1114 * fixed build without CONFIG_RSN_PREAUTH 1115 * fixed FreeBSD build 1116 11172005-06-26 - v0.4.3 1118 * fixed PMKSA caching to copy User-Name and Class attributes so that 1119 RADIUS accounting gets correct information 1120 * start RADIUS accounting only after successful completion of WPA 1121 4-Way Handshake if WPA-PSK is used 1122 * fixed PMKSA caching for the case where STA (re)associates without 1123 first disassociating 1124 11252005-06-12 - v0.4.2 1126 * EAP-PAX is now registered as EAP type 46 1127 * fixed EAP-PAX MAC calculation 1128 * fixed EAP-PAX CK and ICK key derivation 1129 * renamed eap_authenticator configuration variable to eap_server to 1130 better match with RFC 3748 (EAP) terminology 1131 * driver_test: added support for testing hostapd with wpa_supplicant 1132 by using test driver interface without any kernel drivers or network 1133 cards 1134 11352005-05-22 - v0.4.1 1136 * fixed RADIUS server initialization when only auth or acct server 1137 is configured and the other one is left empty 1138 * driver_madwifi: added support for RADIUS accounting 1139 * driver_madwifi: added preliminary support for compiling against 'BSD' 1140 branch of madwifi CVS tree 1141 * driver_madwifi: fixed pairwise key removal to allow WPA reauth 1142 without disassociation 1143 * added support for reading additional certificates from PKCS#12 files 1144 and adding them to the certificate chain 1145 * fixed RADIUS Class attribute processing to only use Access-Accept 1146 packets to update Class; previously, other RADIUS authentication 1147 packets could have cleared Class attribute 1148 * added support for more than one Class attribute in RADIUS packets 1149 * added support for verifying certificate revocation list (CRL) when 1150 using integrated EAP authenticator for EAP-TLS; new hostapd.conf 1151 options 'check_crl'; CRL must be included in the ca_cert file for now 1152 11532005-04-25 - v0.4.0 (beginning of 0.4.x development releases) 1154 * added support for including network information into 1155 EAP-Request/Identity message (ASCII-0 (nul) in eap_message) 1156 (e.g., to implement draft-adrange-eap-network-discovery-07.txt) 1157 * fixed a bug which caused some RSN pre-authentication cases to use 1158 freed memory and potentially crash hostapd 1159 * fixed private key loading for cases where passphrase is not set 1160 * added support for sending TLS alerts and aborting authentication 1161 when receiving a TLS alert 1162 * fixed WPA2 to add PMKSA cache entry when using integrated EAP 1163 authenticator 1164 * fixed PMKSA caching (EAP authentication was not skipped correctly 1165 with the new state machine changes from IEEE 802.1X draft) 1166 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr, 1167 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs 1168 to be added to .config to include IPv6 support); for RADIUS server, 1169 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses 1170 in RADIUS clients file can then use IPv6 format 1171 * added experimental support for EAP-PAX 1172 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with 1173 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch]) 1174 11752005-02-12 - v0.3.7 (beginning of 0.3.x stable releases) 1176 11772005-01-23 - v0.3.5 1178 * added support for configuring a forced PEAP version based on the 1179 Phase 1 identity 1180 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV 1181 to terminate authentication 1182 * fixed EAP identifier duplicate processing with the new IEEE 802.1X 1183 draft 1184 * clear accounting data in the driver when starting a new accounting 1185 session 1186 * driver_madwifi: filter wireless events based on ifindex to allow more 1187 than one network interface to be used 1188 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt 1189 setting if the packet does not pass MIC verification (e.g., due to 1190 incorrect PSK); previously, message 1/4 was not tried again if an 1191 invalid message 2/4 was received 1192 * fixed reconfiguration of RADIUS client retransmission timer when 1193 adding a new message to the pending list; previously, timer was not 1194 updated at this point and if there was a pending message with long 1195 time for the next retry, the new message needed to wait that long for 1196 its first retry, too 1197 11982005-01-09 - v0.3.4 1199 * added support for configuring multiple allowed EAP types for Phase 2 1200 authentication (EAP-PEAP, EAP-TTLS) 1201 * fixed EAPOL-Start processing to trigger WPA reauthentication 1202 (previously, only EAPOL authentication was done) 1203 12042005-01-02 - v0.3.3 1205 * added support for EAP-PEAP in the integrated EAP authenticator 1206 * added support for EAP-GTC in the integrated EAP authenticator 1207 * added support for configuring list of EAP methods for Phase 1 so that 1208 the integrated EAP authenticator can, e.g., use the wildcard entry 1209 for EAP-TLS and EAP-PEAP 1210 * added support for EAP-TTLS in the integrated EAP authenticator 1211 * added support for EAP-SIM in the integrated EAP authenticator 1212 * added support for using hostapd as a RADIUS authentication server 1213 with the integrated EAP authenticator taking care of EAP 1214 authentication (new hostapd.conf options: radius_server_clients and 1215 radius_server_auth_port); this is not included in default build; use 1216 CONFIG_RADIUS_SERVER=y in .config to include 1217 12182004-12-19 - v0.3.2 1219 * removed 'daemonize' configuration file option since it has not really 1220 been used at all for more than year 1221 * driver_madwifi: fixed group key setup and added get_ssid method 1222 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator 1223 12242004-12-12 - v0.3.1 1225 * added support for integrated EAP-TLS authentication (new hostapd.conf 1226 variables: ca_cert, server_cert, private_key, private_key_passwd); 1227 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without 1228 external RADIUS server 1229 * added support for reading PKCS#12 (PFX) files (as a replacement for 1230 PEM/DER) to get certificate and private key (CONFIG_PKCS12) 1231 12322004-12-05 - v0.3.0 (beginning of 0.3.x development releases) 1233 * added support for Acct-{Input,Output}-Gigawords 1234 * added support for Event-Timestamp (in RADIUS Accounting-Requests) 1235 * added support for RADIUS Authentication Client MIB (RFC2618) 1236 * added support for RADIUS Accounting Client MIB (RFC2620) 1237 * made EAP re-authentication period configurable (eap_reauth_period) 1238 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication 1239 * fixed EAPOL state machine to stop if STA is removed during 1240 eapol_sm_step(); this fixes at least one segfault triggering bug with 1241 IEEE 802.11i pre-authentication 1242 * added support for multiple WPA pre-shared keys (e.g., one for each 1243 client MAC address or keys shared by a group of clients); 1244 new hostapd.conf field wpa_psk_file for setting path to a text file 1245 containing PSKs, see hostapd.wpa_psk for an example 1246 * added support for multiple driver interfaces to allow hostapd to be 1247 used with other drivers 1248 * added wired authenticator driver interface (driver=wired in 1249 hostapd.conf, see wired.conf for example configuration) 1250 * added madwifi driver interface (driver=madwifi in hostapd.conf, see 1251 madwifi.conf for example configuration; Note: include files from 1252 madwifi project is needed for building and a configuration file, 1253 .config, needs to be created in hostapd directory with 1254 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd 1255 build) 1256 * fixed an alignment issue that could cause SHA-1 to fail on some 1257 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit 1258 align variables) 1259 * fixed RADIUS reconnection after an error in sending interim 1260 accounting packets 1261 * added hostapd control interface for external programs and an example 1262 CLI, hostapd_cli (like wpa_cli for wpa_supplicant) 1263 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib', 1264 'hostapd_cli sta <addr>') 1265 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11) 1266 * added support for strict GTK rekeying (wpa_strict_rekey in 1267 hostapd.conf) 1268 * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178 1269 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to 1270 IEEE 802.11F-2003) 1271 * added Prism54 driver interface (driver=prism54 in hostapd.conf; 1272 note: .config needs to be created in hostapd directory with 1273 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd 1274 build) 1275 * dual-licensed hostapd (GPLv2 and BSD licenses) 1276 * fixed RADIUS accounting to generate a new session id for cases where 1277 a station reassociates without first being complete deauthenticated 1278 * fixed STA disassociation handler to mark next timeout state to 1279 deauthenticate the station, i.e., skip long wait for inactivity poll 1280 and extra disassociation, if the STA disassociates without 1281 deauthenticating 1282 * added integrated EAP authenticator that can be used instead of 1283 external RADIUS authentication server; currently, only EAP-MD5 is 1284 supported, so this cannot yet be used for key distribution; the EAP 1285 method interface is generic, though, so adding new EAP methods should 1286 be straightforward; new hostapd.conf variables: 'eap_authenticator' 1287 and 'eap_user_file'; this obsoletes "minimal authentication server" 1288 ('minimal_eap' in hostapd.conf) which is now removed 1289 * added support for FreeBSD and driver interface for the BSD net80211 1290 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in 1291 .config); please note that some of the required kernel mods have not 1292 yet been committed 1293 12942004-07-17 - v0.2.4 (beginning of 0.2.x stable releases) 1295 * fixed some accounting cases where Accounting-Start was sent when 1296 IEEE 802.1X port was being deauthorized 1297 12982004-06-20 - v0.2.3 1299 * modified RADIUS client to re-connect the socket in case of certain 1300 error codes that are generated when a network interface state is 1301 changes (e.g., when IP address changes or the interface is set UP) 1302 * fixed couple of cases where EAPOL state for a station was freed 1303 twice causing a segfault for hostapd 1304 * fixed couple of bugs in processing WPA deauthentication (freed data 1305 was used) 1306 13072004-05-31 - v0.2.2 1308 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM) 1309 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix 1310 cases where STAs dropped multicast frames as replay attacks 1311 * added support for copying RADIUS Attribute 'Class' from 1312 authentication messages into accounting messages 1313 * send canned EAP failure if RADIUS server sends Access-Reject without 1314 EAP message (previously, Supplicant was not notified in this case) 1315 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do 1316 not start EAPOL state machines if the STA selected to use WPA-PSK) 1317 13182004-05-06 - v0.2.1 1319 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality 1320 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA 1321 (i.e., IEEE 802.11i/D3.0) 1322 - supports WPA-only, RSN-only, and mixed WPA/RSN mode 1323 - both WPA-PSK and WPA-RADIUS/EAP are supported 1324 - PMKSA caching and pre-authentication 1325 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase, 1326 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey, 1327 rsn_preauth, rsn_preauth_interfaces 1328 * fixed interim accounting to remove any pending accounting messages 1329 to the STA before sending a new one 1330 13312004-02-15 - v0.2.0 1332 * added support for Acct-Interim-Interval: 1333 - draft-ietf-radius-acct-interim-01.txt 1334 - use Acct-Interim-Interval attribute from Access-Accept if local 1335 'radius_acct_interim_interval' is not set 1336 - allow different update intervals for each STA 1337 * fixed event loop to call signal handlers only after returning from 1338 the real signal handler 1339 * reset sta->timeout_next after successful association to make sure 1340 that the previously registered inactivity timer will not remove the 1341 STA immediately (e.g., if STA deauthenticates and re-associates 1342 before the timer is triggered). 1343 * added new hostapd.conf variable, nas_identifier, that can be used to 1344 add an optional RADIUS Attribute, NAS-Identifier, into authentication 1345 and accounting messages 1346 * added support for Accounting-On and Accounting-Off messages 1347 * fixed accounting session handling to send Accounting-Start only once 1348 per session and not to send Accounting-Stop if the session was not 1349 initialized properly 1350 * fixed Accounting-Stop statistics in cases where the message was 1351 previously sent after the kernel entry for the STA (and/or IEEE 1352 802.1X data) was removed 1353 1354 1355Note: 1356 1357Older changes up to and including v0.1.0 are included in the ChangeLog 1358of the Host AP driver. 1359
