v1.0 528 * Add channel selection support in hostapd. See hostapd.conf. 529 * Add support for IEEE 802.11v Time Advertisement mechanism with UTC 530 TSF offset. See hostapd.conf for config info. 531 * Delay STA entry removal until Deauth/Disassoc TX status in AP mode. 532 This allows the driver to use PS buffering of Deauthentication and 533 Disassociation frames when the STA is in power save sleep. Only 534 available with drivers that provide TX status events for Deauth/ 535 Disassoc frames (nl80211). 536 * Allow PMKSA caching to be disabled on the Authenticator. See 537 hostap.conf config parameter disable_pmksa_caching. 538 * atheros: Add support for IEEE 802.11w configuration. 539 * bsd: Add support for setting HT values in IFM_MMASK. 540 * Allow client isolation to be configured with ap_isolate. Client 541 isolation can be used to prevent low-level bridging of frames 542 between associated stations in the BSS. By default, this bridging 543 is allowed. 544 * Allow coexistance of HT BSSes with WEP/TKIP BSSes. 545 * Add require_ht config parameter, which can be used to configure 546 hostapd to reject association with any station that does not support 547 HT PHY. 548 * Add support for writing debug log to a file using "-f" option. Also 549 add relog CLI command to re-open the log file. 550 * Add bridge handling for WDS STA interfaces. By default they are 551 added to the configured bridge of the AP interface (if present), 552 but the user can also specify a separate bridge using cli command 553 wds_bridge. 554 * hostapd_cli: 555 - Add wds_bridge command for specifying bridge for WDS STA 556 interfaces. 557 - Add relog command for reopening log file. 558 - Send AP-STA-DISCONNECTED event when an AP disconnects a station 559 due to inactivity. 560 - Add wps_config ctrl_interface command for configuring AP. This 561 command can be used to configure the AP using the internal WPS 562 registrar. It works in the same way as new AP settings received 563 from an ER. 564 - Many WPS/WPS ER commands - see WPS/WPS ER sections for details. 565 - Add command get version, that returns hostapd version string. 566 * WNM: Add BSS Transition Management Request for ESS Disassoc Imminent. 567 Use hostapd_cli ess_disassoc (STA addr) (URL) to send the 568 notification to the STA. 569 * Allow AP mode to disconnect STAs based on low ACK condition (when 570 the data connection is not working properly, e.g., due to the STA 571 going outside the range of the AP). Disabled by default, enable by 572 config option disassoc_low_ack. 573 * Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad 574 config file. 575 * WPS: 576 - Send AP Settings as a wrapped Credential attribute to ctrl_iface 577 in WPS-NEW-AP-SETTINGS. 578 - Dispatch more WPS events through hostapd ctrl_iface. 579 - Add mechanism for indicating non-standard WPS errors. 580 - Change concurrent radio AP to use only one WPS UPnP instance. 581 - Add wps_check_pin command for processing PIN from user input. 582 UIs can use this command to process a PIN entered by a user and to 583 validate the checksum digit (if present). 584 - Add hostap_cli get_config command to display current AP config. 585 - Add new hostapd_cli command, wps_ap_pin, to manage AP PIN at 586 runtime and support dynamic AP PIN management. 587 - Disable AP PIN after 10 consecutive failures. Slow down attacks 588 on failures up to 10. 589 - Allow AP to start in Enrollee mode without AP PIN for probing, 590 to be compatible with Windows 7. 591 - Add Config Error into WPS-FAIL events to provide more info 592 to the user on how to resolve the issue. 593 - When controlling multiple interfaces: 594 - apply WPS commands to all interfaces configured to use WPS 595 - apply WPS config changes to all interfaces that use WPS 596 - when an attack is detected on any interface, disable AP PIN on 597 all interfaces 598 * WPS ER: 599 - Show SetSelectedRegistrar events as ctrl_iface events. 600 - Add special AP Setup Locked mode to allow read only ER. 601 ap_setup_locked=2 can now be used to enable a special mode where 602 WPS ER can learn the current AP settings, but cannot change them. 603 * WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2) 604 - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool 605 for testing protocol extensibility. 606 - Add build option CONFIG_WPS_STRICT to allow disabling of WPS 607 workarounds. 608 - Add support for AuthorizedMACs attribute. 609 * TDLS: 610 - Allow TDLS use or TDLS channel switching in the BSS to be 611 prohibited in the BSS, using config params tdls_prohibit and 612 tdls_prohibit_chan_switch. 613 * EAP server: Add support for configuring fragment size (see 614 fragment_size in hostapd.conf). 615 * wlantest: Add a tool wlantest for IEEE802.11 protocol testing. 616 wlantest can be used to capture frames from a monitor interface 617 for realtime capturing or from pcap files for offline analysis. 618 * Interworking: Support added for 802.11u. Enable in .config with 619 CONFIG_INTERWORKING. See hostapd.conf for config parameters for 620 interworking. 621 * Android: Add build and runtime support for Android hostapd. 622 * Add a new debug message level for excessive information. Use 623 -ddd to enable. 624 * TLS: Add support for tls_disable_time_checks=1 in client mode. 625 * Internal TLS: 626 - Add support for TLS v1.1 (RFC 4346). Enable with build parameter 627 CONFIG_TLSV11. 628 - Add domainComponent parser for X.509 names 629 * Reorder some IEs to get closer to IEEE 802.11 standard. Move 630 WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames. 631 Move HT IEs to be later in (Re)Assoc Resp. 632 * Many bugfixes. 633 6342010-04-18 - v0.7.2 635 * fix WPS internal Registrar use when an external Registrar is also 636 active 637 * bsd: Cleaned up driver wrapper and added various low-level 638 configuration options 639 * TNC: fixed issues with fragmentation 640 * EAP-TNC: add Flags field into fragment acknowledgement (needed to 641 interoperate with other implementations; may potentially breaks 642 compatibility with older wpa_supplicant/hostapd versions) 643 * cleaned up driver wrapper API for multi-BSS operations 644 * nl80211: fix multi-BSS and VLAN operations 645 * fix number of issues with IEEE 802.11r/FT; this version is not 646 backwards compatible with old versions 647 * add SA Query Request processing in AP mode (IEEE 802.11w) 648 * fix IGTK PN in group rekeying (IEEE 802.11w) 649 * fix WPS PBC session overlap detection to use correct attribute 650 * hostapd_notif_Assoc() can now be called with all IEs to simplify 651 driver wrappers 652 * work around interoperability issue with some WPS External Registrar 653 implementations 654 * nl80211: fix WPS IE update 655 * hostapd_cli: add support for action script operations (run a script 656 on hostapd events) 657 * fix DH padding with internal crypto code (mainly, for WPS) 658 * fix WPS association with both WPS IE and WPA/RSN IE present with 659 driver wrappers that use hostapd MLME (e.g., nl80211) 660 6612010-01-16 - v0.7.1 662 * cleaned up driver wrapper API (struct wpa_driver_ops); the new API 663 is not fully backwards compatible, so out-of-tree driver wrappers 664 will need modifications 665 * cleaned up various module interfaces 666 * merge hostapd and wpa_supplicant developers' documentation into a 667 single document 668 * fixed HT Capabilities IE with nl80211 drivers 669 * moved generic AP functionality code into src/ap 670 * WPS: handle Selected Registrar as union of info from all Registrars 671 * remove obsolte Prism54.org driver wrapper 672 * added internal debugging mechanism with backtrace support and memory 673 allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y) 674 * EAP-FAST server: piggyback Phase 2 start with the end of Phase 1 675 * WPS: add support for dynamically selecting whether to provision the 676 PSK as an ASCII passphrase or PSK 677 * added support for WDS (4-address frame) mode with per-station virtual 678 interfaces (wds_sta=1 in config file; only supported with 679 driver=nl80211 for now) 680 * fixed WPS Probe Request processing to handle missing required 681 attribute 682 * fixed PKCS#12 use with OpenSSL 1.0.0 683 * detect bridge interface automatically so that bridge parameter in 684 hostapd.conf becomes optional (though, it may now be used to 685 automatically add then WLAN interface into a bridge with 686 driver=nl80211) 687 6882009-11-21 - v0.7.0 689 * increased hostapd_cli ping interval to 5 seconds and made this 690 configurable with a new command line options (-G<seconds>) 691 * driver_nl80211: use Linux socket filter to improve performance 692 * added support for external Registrars with WPS (UPnP transport) 693 * 802.11n: scan for overlapping BSSes before starting 20/40 MHz channel 694 * driver_nl80211: fixed STA accounting data collection (TX/RX bytes 695 reported correctly; TX/RX packets not yet available from kernel) 696 * added support for WPS USBA out-of-band mechanism with USB Flash 697 Drives (UFD) (CONFIG_WPS_UFD=y) 698 * fixed EAPOL/EAP reauthentication when using an external RADIUS 699 authentication server 700 * fixed TNC with EAP-TTLS 701 * fixed IEEE 802.11r key derivation function to match with the standard 702 (note: this breaks interoperability with previous version) [Bug 303] 703 * fixed SHA-256 based key derivation function to match with the 704 standard when using CCMP (for IEEE 802.11r and IEEE 802.11w) 705 (note: this breaks interoperability with previous version) [Bug 307] 706 * added number of code size optimizations to remove unnecessary 707 functionality from the program binary based on build configuration 708 (part of this automatic; part configurable with CONFIG_NO_* build 709 options) 710 * use shared driver wrapper files with wpa_supplicant 711 * driver_nl80211: multiple updates to provide support for new Linux 712 nl80211/mac80211 functionality 713 * updated management frame protection to use IEEE Std 802.11w-2009 714 * fixed number of small WPS issues and added workarounds to 715 interoperate with common deployed broken implementations 716 * added some IEEE 802.11n co-existence rules to disable 40 MHz channels 717 or modify primary/secondary channels if needed based on neighboring 718 networks 719 * added support for NFC out-of-band mechanism with WPS 720 * added preliminary support for IEEE 802.11r RIC processing 721 7222009-01-06 - v0.6.7 723 * added support for Wi-Fi Protected Setup (WPS) 724 (hostapd can now be configured to act as an integrated WPS Registrar 725 and provision credentials for WPS Enrollees using PIN and PBC 726 methods; external wireless Registrar can configure the AP, but 727 external WLAN Manager Registrars are not supported); WPS support can 728 be enabled by adding CONFIG_WPS=y into .config and setting the 729 runtime configuration variables in hostapd.conf (see WPS section in 730 the example configuration file); new hostapd_cli commands wps_pin and 731 wps_pbc are used to configure WPS negotiation; see README-WPS for 732 more details 733 * added IEEE 802.11n HT capability configuration (ht_capab) 734 * added support for generating Country IE based on nl80211 regulatory 735 information (added if ieee80211d=1 in configuration) 736 * fixed WEP authentication (both Open System and Shared Key) with 737 mac80211 738 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf) 739 * added support for using driver_test over UDP socket 740 * changed EAP-GPSK to use the IANA assigned EAP method type 51 741 * updated management frame protection to use IEEE 802.11w/D7.0 742 * fixed retransmission of EAP requests if no response is received 743 7442008-11-23 - v0.6.6 745 * added a new configuration option, wpa_ptk_rekey, that can be used to 746 enforce frequent PTK rekeying, e.g., to mitigate some attacks against 747 TKIP deficiencies 748 * updated OpenSSL code for EAP-FAST to use an updated version of the 749 session ticket overriding API that was included into the upstream 750 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is 751 needed with that version anymore) 752 * changed channel flags configuration to read the information from 753 the driver (e.g., via driver_nl80211 when using mac80211) instead of 754 using hostapd as the source of the regulatory information (i.e., 755 information from CRDA is now used with mac80211); this allows 5 GHz 756 channels to be used with hostapd (if allowed in the current 757 regulatory domain) 758 * fixed EAP-TLS message processing for the last TLS message if it is 759 large enough to require fragmentation (e.g., if a large Session 760 Ticket data is included) 761 * fixed listen interval configuration for nl80211 drivers 762 7632008-11-01 - v0.6.5 764 * added support for SHA-256 as X.509 certificate digest when using the 765 internal X.509/TLSv1 implementation 766 * fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer 767 identity lengths) 768 * fixed internal TLSv1 implementation for abbreviated handshake (used 769 by EAP-FAST server) 770 * added support for setting VLAN ID for STAs based on local MAC ACL 771 (accept_mac_file) as an alternative for RADIUS server-based 772 configuration 773 * updated management frame protection to use IEEE 802.11w/D6.0 774 (adds a new association ping to protect against unauthenticated 775 authenticate or (re)associate request frames dropping association) 776 * added support for using SHA256-based stronger key derivation for WPA2 777 (IEEE 802.11w) 778 * added new "driver wrapper" for RADIUS-only configuration 779 (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config) 780 * fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2) 781 is enabled in configuration 782 * changed EAP-FAST configuration to use separate fields for A-ID and 783 A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed 784 16-octet len binary value for better interoperability with some peer 785 implementations; eap_fast_a_id is now configured as a hex string 786 * driver_nl80211: Updated to match the current Linux mac80211 AP mode 787 configuration (wireless-testing.git and Linux kernel releases 788 starting from 2.6.29) 789 7902008-08-10 - v0.6.4 791 * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2 792 Identity Request if identity is already known 793 * added support for EAP Sequences in EAP-FAST Phase 2 794 * added support for EAP-TNC (Trusted Network Connect) 795 (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST 796 changes needed to run two methods in sequence (IF-T) and the IF-IMV 797 and IF-TNCCS interfaces from TNCS) 798 * added support for optional cryptobinding with PEAPv0 799 * added fragmentation support for EAP-TNC 800 * added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled) 801 data 802 * added support for opportunistic key caching (OKC) 803 8042008-02-22 - v0.6.3 805 * fixed Reassociation Response callback processing when using internal 806 MLME (driver_{hostap,nl80211,test}.c) 807 * updated FT support to use the latest draft, IEEE 802.11r/D9.0 808 * copy optional Proxy-State attributes into RADIUS response when acting 809 as a RADIUS authentication server 810 * fixed EAPOL state machine to handle a case in which no response is 811 received from the RADIUS authentication server; previous version 812 could have triggered a crash in some cases after a timeout 813 * fixed EAP-SIM/AKA realm processing to allow decorated usernames to 814 be used 815 * added a workaround for EAP-SIM/AKA peers that include incorrect null 816 termination in the username 817 * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER 818 attribute in notification messages only when using fast 819 reauthentication 820 * fixed EAP-SIM Start response processing for fast reauthentication 821 case 822 * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST} 823 phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method 824 8252008-01-01 - v0.6.2 826 * fixed EAP-SIM and EAP-AKA message parser to validate attribute 827 lengths properly to avoid potential crash caused by invalid messages 828 * added data structure for storing allocated buffers (struct wpabuf); 829 this does not affect hostapd usage, but many of the APIs changed 830 and various interfaces (e.g., EAP) is not compatible with old 831 versions 832 * added support for protecting EAP-AKA/Identity messages with 833 AT_CHECKCODE (optional feature in RFC 4187) 834 * added support for protected result indication with AT_RESULT_IND for 835 EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1) 836 * added support for configuring EAP-TTLS phase 2 non-EAP methods in 837 EAP server configuration; previously all four were enabled for every 838 phase 2 user, now all four are disabled by default and need to be 839 enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP, 840 TTLS-MSCHAPV2 841 * removed old debug printing mechanism and the related 'debug' 842 parameter in the configuration file; debug verbosity is now set with 843 -d (or -dd) command line arguments 844 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt); 845 only shared key/password authentication is supported in this version 846 8472007-11-24 - v0.6.1 848 * added experimental, integrated TLSv1 server implementation with the 849 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by 850 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in 851 .config); this can be useful, e.g., if the target system does not 852 have a suitable TLS library and a minimal code size is required 853 * added support for EAP-FAST server method to the integrated EAP 854 server 855 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 856 draft (draft-ietf-emu-eap-gpsk-07.txt) 857 * added a new configuration parameter, rsn_pairwise, to allow different 858 pairwise cipher suites to be enabled for WPA and RSN/WPA2 859 (note: if wpa_pairwise differs from rsn_pairwise, the driver will 860 either need to support this or will have to use the WPA/RSN IEs from 861 hostapd; currently, the included madwifi and bsd driver interfaces do 862 not have support for this) 863 * updated FT support to use the latest draft, IEEE 802.11r/D8.0 864 8652007-05-28 - v0.6.0 866 * added experimental IEEE 802.11r/D6.0 support 867 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48 868 * updated EAP-PSK to use the IANA-allocated EAP type 47 869 * fixed EAP-PSK bit ordering of the Flags field 870 * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs 871 by reading wpa_psk_file [Bug 181] 872 * fixed EAP-TTLS AVP parser processing for too short AVP lengths 873 * fixed IPv6 connection to RADIUS accounting server 874 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 875 draft (draft-ietf-emu-eap-gpsk-04.txt) 876 * hlr_auc_gw: read GSM triplet file into memory and rotate through the 877 entries instead of only using the same three triplets every time 878 (this does not work properly with tests using multiple clients, but 879 provides bit better triplet data for testing a single client; anyway, 880 if a better quality triplets are needed, GSM-Milenage should be used 881 instead of hardcoded triplet file) 882 * fixed EAP-MSCHAPv2 server to use a space between S and M parameters 883 in Success Request [Bug 203] 884 * added support for sending EAP-AKA Notifications in error cases 885 * updated to use IEEE 802.11w/D2.0 for management frame protection 886 (still experimental) 887 * RADIUS server: added support for processing duplicate messages 888 (retransmissions from RADIUS client) by replying with the previous 889 reply 890 8912006-11-24 - v0.5.6 892 * added support for configuring and controlling multiple BSSes per 893 radio interface (bss=<ifname> in hostapd.conf); this is only 894 available with Devicescape and test driver interfaces 895 * fixed PMKSA cache update in the end of successful RSN 896 pre-authentication 897 * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID 898 for each STA based on RADIUS Access-Accept attributes); this requires 899 VLAN support from the kernel driver/802.11 stack and this is 900 currently only available with Devicescape and test driver interfaces 901 * driver_madwifi: fixed configuration of unencrypted modes (plaintext 902 and IEEE 802.1X without WEP) 903 * removed STAKey handshake since PeerKey handshake has replaced it in 904 IEEE 802.11ma and there are no known deployments of STAKey 905 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 906 draft (draft-ietf-emu-eap-gpsk-01.txt) 907 * added preliminary implementation of IEEE 802.11w/D1.0 (management 908 frame protection) 909 (Note: this requires driver support to work properly.) 910 (Note2: IEEE 802.11w is an unapproved draft and subject to change.) 911 * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM) 912 * hlr_auc_gw: added support for reading per-IMSI Milenage keys and 913 parameters from a text file to make it possible to implement proper 914 GSM/UMTS authentication server for multiple SIM/USIM cards using 915 EAP-SIM/EAP-AKA 916 * fixed session timeout processing with drivers that do not use 917 ieee802_11.c (e.g., madwifi) 918 9192006-08-27 - v0.5.5 920 * added 'hostapd_cli new_sta <addr>' command for adding a new STA into 921 hostapd (e.g., to initialize wired network authentication based on an 922 external signal) 923 * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when 924 using WPA2 even if PMKSA caching is not used 925 * added -P<pid file> argument for hostapd to write the current process 926 id into a file 927 * added support for RADIUS Authentication Server MIB (RFC 2619) 928 9292006-06-20 - v0.5.4 930 * fixed nt_password_hash build [Bug 144] 931 * added PeerKey handshake implementation for IEEE 802.11e 932 direct link setup (DLS) to replace STAKey handshake 933 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK, 934 draft-clancy-emu-eap-shared-secret-00.txt) 935 * fixed a segmentation fault when RSN pre-authentication was completed 936 successfully [Bug 152] 937 9382006-04-27 - v0.5.3 939 * do not build nt_password_hash and hlr_auc_gw by default to avoid 940 requiring a TLS library for a successful build; these programs can be 941 build with 'make nt_password_hash' and 'make hlr_auc_gw' 942 * added a new configuration option, eapol_version, that can be used to 943 set EAPOL version to 1 (default is 2) to work around broken client 944 implementations that drop EAPOL frames which use version number 2 945 [Bug 89] 946 * added support for EAP-SAKE (no EAP method number allocated yet, so 947 this is using the same experimental type 255 as EAP-PSK) 948 * fixed EAP-MSCHAPv2 message length validation 949 9502006-03-19 - v0.5.2 951 * fixed stdarg use in hostapd_logger(): if both stdout and syslog 952 logging was enabled, hostapd could trigger a segmentation fault in 953 vsyslog on some CPU -- C library combinations 954 * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external 955 program to make it easier to use for implementing real SS7 gateway; 956 eap_sim_db is not anymore used as a file name for GSM authentication 957 triplets; instead, it is path to UNIX domain socket that will be used 958 to communicate with the external gateway program (e.g., hlr_auc_gw) 959 * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses 960 local information (GSM authentication triplets from a text file and 961 hardcoded AKA authentication data); this can be used to test EAP-SIM 962 and EAP-AKA 963 * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw 964 to make it possible to test EAP-AKA with real USIM cards (this is 965 disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw 966 to enable this) 967 * driver_madwifi: added support for getting station RSN IE from 968 madwifi-ng svn r1453 and newer; this fixes RSN that was apparently 969 broken with earlier change (r1357) in the driver 970 * changed EAP method registration to use a dynamic list of methods 971 instead of a static list generated at build time 972 * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE) 973 [Bug 125] 974 * added ap_max_inactivity configuration parameter 975 9762006-01-29 - v0.5.1 977 * driver_test: added better support for multiple APs and STAs by using 978 a directory with sockets that include MAC address for each device in 979 the name (test_socket=DIR:/tmp/test) 980 * added support for EAP expanded type (vendor specific EAP methods) 981 9822005-12-18 - v0.5.0 (beginning of 0.5.x development releases) 983 * added experimental STAKey handshake implementation for IEEE 802.11e 984 direct link setup (DLS); note: this is disabled by default in both 985 build and runtime configuration (can be enabled with CONFIG_STAKEY=y 986 and stakey=1) 987 * added support for EAP methods to use callbacks to external programs 988 by buffering a pending request and processing it after the EAP method 989 is ready to continue 990 * improved EAP-SIM database interface to allow external request to GSM 991 HLR/AuC without blocking hostapd process 992 * added support for using EAP-SIM pseudonyms and fast re-authentication 993 * added support for EAP-AKA in the integrated EAP authenticator 994 * added support for matching EAP identity prefixes (e.g., "1"*) in EAP 995 user database to allow EAP-SIM/AKA selection without extra roundtrip 996 for EAP-Nak negotiation 997 * added support for storing EAP user password as NtPasswordHash instead 998 of plaintext password when using MSCHAP or MSCHAPv2 for 999 authentication (hash:<16-octet hex value>); added nt_password_hash 1000 tool for hashing password to generate NtPasswordHash 1001 10022005-11-20 - v0.4.7 (beginning of 0.4.x stable releases) 1003 * driver_wired: fixed EAPOL sending to optionally use PAE group address 1004 as the destination instead of supplicant MAC address; this is 1005 disabled by default, but should be enabled with use_pae_group_addr=1 1006 in configuration file if the wired interface is used by only one 1007 device at the time (common switch configuration) 1008 * driver_madwifi: configure driver to use TKIP countermeasures in order 1009 to get correct behavior (IEEE 802.11 association failing; previously, 1010 association succeeded, but hostpad forced disassociation immediately) 1011 * driver_madwifi: added support for madwifi-ng 1012 10132005-10-27 - v0.4.6 1014 * added support for replacing user identity from EAP with RADIUS 1015 User-Name attribute from Access-Accept message, if that is included, 1016 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get 1017 tunneled identity into accounting messages when the RADIUS server 1018 does not support better way of doing this with Class attribute) 1019 * driver_madwifi: fixed EAPOL packet receive for configuration where 1020 ath# is part of a bridge interface 1021 * added a configuration file and log analyzer script for logwatch 1022 * fixed EAPOL state machine step function to process all state 1023 transitions before processing new events; this resolves a race 1024 condition in which EAPOL-Start message could trigger hostapd to send 1025 two EAP-Response/Identity frames to the authentication server 1026 10272005-09-25 - v0.4.5 1028 * added client CA list to the TLS certificate request in order to make 1029 it easier for the client to select which certificate to use 1030 * added experimental support for EAP-PSK 1031 * added support for WE-19 (hostap, madwifi) 1032 10332005-08-21 - v0.4.4 1034 * fixed build without CONFIG_RSN_PREAUTH 1035 * fixed FreeBSD build 1036 10372005-06-26 - v0.4.3 1038 * fixed PMKSA caching to copy User-Name and Class attributes so that 1039 RADIUS accounting gets correct information 1040 * start RADIUS accounting only after successful completion of WPA 1041 4-Way Handshake if WPA-PSK is used 1042 * fixed PMKSA caching for the case where STA (re)associates without 1043 first disassociating 1044 10452005-06-12 - v0.4.2 1046 * EAP-PAX is now registered as EAP type 46 1047 * fixed EAP-PAX MAC calculation 1048 * fixed EAP-PAX CK and ICK key derivation 1049 * renamed eap_authenticator configuration variable to eap_server to 1050 better match with RFC 3748 (EAP) terminology 1051 * driver_test: added support for testing hostapd with wpa_supplicant 1052 by using test driver interface without any kernel drivers or network 1053 cards 1054 10552005-05-22 - v0.4.1 1056 * fixed RADIUS server initialization when only auth or acct server 1057 is configured and the other one is left empty 1058 * driver_madwifi: added support for RADIUS accounting 1059 * driver_madwifi: added preliminary support for compiling against 'BSD' 1060 branch of madwifi CVS tree 1061 * driver_madwifi: fixed pairwise key removal to allow WPA reauth 1062 without disassociation 1063 * added support for reading additional certificates from PKCS#12 files 1064 and adding them to the certificate chain 1065 * fixed RADIUS Class attribute processing to only use Access-Accept 1066 packets to update Class; previously, other RADIUS authentication 1067 packets could have cleared Class attribute 1068 * added support for more than one Class attribute in RADIUS packets 1069 * added support for verifying certificate revocation list (CRL) when 1070 using integrated EAP authenticator for EAP-TLS; new hostapd.conf 1071 options 'check_crl'; CRL must be included in the ca_cert file for now 1072 10732005-04-25 - v0.4.0 (beginning of 0.4.x development releases) 1074 * added support for including network information into 1075 EAP-Request/Identity message (ASCII-0 (nul) in eap_message) 1076 (e.g., to implement draft-adrange-eap-network-discovery-07.txt) 1077 * fixed a bug which caused some RSN pre-authentication cases to use 1078 freed memory and potentially crash hostapd 1079 * fixed private key loading for cases where passphrase is not set 1080 * added support for sending TLS alerts and aborting authentication 1081 when receiving a TLS alert 1082 * fixed WPA2 to add PMKSA cache entry when using integrated EAP 1083 authenticator 1084 * fixed PMKSA caching (EAP authentication was not skipped correctly 1085 with the new state machine changes from IEEE 802.1X draft) 1086 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr, 1087 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs 1088 to be added to .config to include IPv6 support); for RADIUS server, 1089 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses 1090 in RADIUS clients file can then use IPv6 format 1091 * added experimental support for EAP-PAX 1092 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with 1093 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch]) 1094 10952005-02-12 - v0.3.7 (beginning of 0.3.x stable releases) 1096 10972005-01-23 - v0.3.5 1098 * added support for configuring a forced PEAP version based on the 1099 Phase 1 identity 1100 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV 1101 to terminate authentication 1102 * fixed EAP identifier duplicate processing with the new IEEE 802.1X 1103 draft 1104 * clear accounting data in the driver when starting a new accounting 1105 session 1106 * driver_madwifi: filter wireless events based on ifindex to allow more 1107 than one network interface to be used 1108 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt 1109 setting if the packet does not pass MIC verification (e.g., due to 1110 incorrect PSK); previously, message 1/4 was not tried again if an 1111 invalid message 2/4 was received 1112 * fixed reconfiguration of RADIUS client retransmission timer when 1113 adding a new message to the pending list; previously, timer was not 1114 updated at this point and if there was a pending message with long 1115 time for the next retry, the new message needed to wait that long for 1116 its first retry, too 1117 11182005-01-09 - v0.3.4 1119 * added support for configuring multiple allowed EAP types for Phase 2 1120 authentication (EAP-PEAP, EAP-TTLS) 1121 * fixed EAPOL-Start processing to trigger WPA reauthentication 1122 (previously, only EAPOL authentication was done) 1123 11242005-01-02 - v0.3.3 1125 * added support for EAP-PEAP in the integrated EAP authenticator 1126 * added support for EAP-GTC in the integrated EAP authenticator 1127 * added support for configuring list of EAP methods for Phase 1 so that 1128 the integrated EAP authenticator can, e.g., use the wildcard entry 1129 for EAP-TLS and EAP-PEAP 1130 * added support for EAP-TTLS in the integrated EAP authenticator 1131 * added support for EAP-SIM in the integrated EAP authenticator 1132 * added support for using hostapd as a RADIUS authentication server 1133 with the integrated EAP authenticator taking care of EAP 1134 authentication (new hostapd.conf options: radius_server_clients and 1135 radius_server_auth_port); this is not included in default build; use 1136 CONFIG_RADIUS_SERVER=y in .config to include 1137 11382004-12-19 - v0.3.2 1139 * removed 'daemonize' configuration file option since it has not really 1140 been used at all for more than year 1141 * driver_madwifi: fixed group key setup and added get_ssid method 1142 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator 1143 11442004-12-12 - v0.3.1 1145 * added support for integrated EAP-TLS authentication (new hostapd.conf 1146 variables: ca_cert, server_cert, private_key, private_key_passwd); 1147 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without 1148 external RADIUS server 1149 * added support for reading PKCS#12 (PFX) files (as a replacement for 1150 PEM/DER) to get certificate and private key (CONFIG_PKCS12) 1151 11522004-12-05 - v0.3.0 (beginning of 0.3.x development releases) 1153 * added support for Acct-{Input,Output}-Gigawords 1154 * added support for Event-Timestamp (in RADIUS Accounting-Requests) 1155 * added support for RADIUS Authentication Client MIB (RFC2618) 1156 * added support for RADIUS Accounting Client MIB (RFC2620) 1157 * made EAP re-authentication period configurable (eap_reauth_period) 1158 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication 1159 * fixed EAPOL state machine to stop if STA is removed during 1160 eapol_sm_step(); this fixes at least one segfault triggering bug with 1161 IEEE 802.11i pre-authentication 1162 * added support for multiple WPA pre-shared keys (e.g., one for each 1163 client MAC address or keys shared by a group of clients); 1164 new hostapd.conf field wpa_psk_file for setting path to a text file 1165 containing PSKs, see hostapd.wpa_psk for an example 1166 * added support for multiple driver interfaces to allow hostapd to be 1167 used with other drivers 1168 * added wired authenticator driver interface (driver=wired in 1169 hostapd.conf, see wired.conf for example configuration) 1170 * added madwifi driver interface (driver=madwifi in hostapd.conf, see 1171 madwifi.conf for example configuration; Note: include files from 1172 madwifi project is needed for building and a configuration file, 1173 .config, needs to be created in hostapd directory with 1174 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd 1175 build) 1176 * fixed an alignment issue that could cause SHA-1 to fail on some 1177 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit 1178 align variables) 1179 * fixed RADIUS reconnection after an error in sending interim 1180 accounting packets 1181 * added hostapd control interface for external programs and an example 1182 CLI, hostapd_cli (like wpa_cli for wpa_supplicant) 1183 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib', 1184 'hostapd_cli sta <addr>') 1185 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11) 1186 * added support for strict GTK rekeying (wpa_strict_rekey in 1187 hostapd.conf) 1188 * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178 1189 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to 1190 IEEE 802.11F-2003) 1191 * added Prism54 driver interface (driver=prism54 in hostapd.conf; 1192 note: .config needs to be created in hostapd directory with 1193 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd 1194 build) 1195 * dual-licensed hostapd (GPLv2 and BSD licenses) 1196 * fixed RADIUS accounting to generate a new session id for cases where 1197 a station reassociates without first being complete deauthenticated 1198 * fixed STA disassociation handler to mark next timeout state to 1199 deauthenticate the station, i.e., skip long wait for inactivity poll 1200 and extra disassociation, if the STA disassociates without 1201 deauthenticating 1202 * added integrated EAP authenticator that can be used instead of 1203 external RADIUS authentication server; currently, only EAP-MD5 is 1204 supported, so this cannot yet be used for key distribution; the EAP 1205 method interface is generic, though, so adding new EAP methods should 1206 be straightforward; new hostapd.conf variables: 'eap_authenticator' 1207 and 'eap_user_file'; this obsoletes "minimal authentication server" 1208 ('minimal_eap' in hostapd.conf) which is now removed 1209 * added support for FreeBSD and driver interface for the BSD net80211 1210 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in 1211 .config); please note that some of the required kernel mods have not 1212 yet been committed 1213 12142004-07-17 - v0.2.4 (beginning of 0.2.x stable releases) 1215 * fixed some accounting cases where Accounting-Start was sent when 1216 IEEE 802.1X port was being deauthorized 1217 12182004-06-20 - v0.2.3 1219 * modified RADIUS client to re-connect the socket in case of certain 1220 error codes that are generated when a network interface state is 1221 changes (e.g., when IP address changes or the interface is set UP) 1222 * fixed couple of cases where EAPOL state for a station was freed 1223 twice causing a segfault for hostapd 1224 * fixed couple of bugs in processing WPA deauthentication (freed data 1225 was used) 1226 12272004-05-31 - v0.2.2 1228 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM) 1229 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix 1230 cases where STAs dropped multicast frames as replay attacks 1231 * added support for copying RADIUS Attribute 'Class' from 1232 authentication messages into accounting messages 1233 * send canned EAP failure if RADIUS server sends Access-Reject without 1234 EAP message (previously, Supplicant was not notified in this case) 1235 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do 1236 not start EAPOL state machines if the STA selected to use WPA-PSK) 1237 12382004-05-06 - v0.2.1 1239 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality 1240 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA 1241 (i.e., IEEE 802.11i/D3.0) 1242 - supports WPA-only, RSN-only, and mixed WPA/RSN mode 1243 - both WPA-PSK and WPA-RADIUS/EAP are supported 1244 - PMKSA caching and pre-authentication 1245 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase, 1246 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey, 1247 rsn_preauth, rsn_preauth_interfaces 1248 * fixed interim accounting to remove any pending accounting messages 1249 to the STA before sending a new one 1250 12512004-02-15 - v0.2.0 1252 * added support for Acct-Interim-Interval: 1253 - draft-ietf-radius-acct-interim-01.txt 1254 - use Acct-Interim-Interval attribute from Access-Accept if local 1255 'radius_acct_interim_interval' is not set 1256 - allow different update intervals for each STA 1257 * fixed event loop to call signal handlers only after returning from 1258 the real signal handler 1259 * reset sta->timeout_next after successful association to make sure 1260 that the previously registered inactivity timer will not remove the 1261 STA immediately (e.g., if STA deauthenticates and re-associates 1262 before the timer is triggered). 1263 * added new hostapd.conf variable, nas_identifier, that can be used to 1264 add an optional RADIUS Attribute, NAS-Identifier, into authentication 1265 and accounting messages 1266 * added support for Accounting-On and Accounting-Off messages 1267 * fixed accounting session handling to send Accounting-Start only once 1268 per session and not to send Accounting-Stop if the session was not 1269 initialized properly 1270 * fixed Accounting-Stop statistics in cases where the message was 1271 previously sent after the kernel entry for the STA (and/or IEEE 1272 802.1X data) was removed 1273 1274 1275Note: 1276 1277Older changes up to and including v0.1.0 are included in the ChangeLog 1278of the Host AP driver. 1279
