Also 525 add relog CLI command to re-open the log file. 526 * Add bridge handling for WDS STA interfaces. By default they are 527 added to the configured bridge of the AP interface (if present), 528 but the user can also specify a separate bridge using cli command 529 wds_bridge. 530 * hostapd_cli: 531 - Add wds_bridge command for specifying bridge for WDS STA 532 interfaces. 533 - Add relog command for reopening log file. 534 - Send AP-STA-DISCONNECTED event when an AP disconnects a station 535 due to inactivity. 536 - Add wps_config ctrl_interface command for configuring AP. This 537 command can be used to configure the AP using the internal WPS 538 registrar. It works in the same way as new AP settings received 539 from an ER. 540 - Many WPS/WPS ER commands - see WPS/WPS ER sections for details. 541 - Add command get version, that returns hostapd version string. 542 * WNM: Add BSS Transition Management Request for ESS Disassoc Imminent. 543 Use hostapd_cli ess_disassoc (STA addr) (URL) to send the 544 notification to the STA. 545 * Allow AP mode to disconnect STAs based on low ACK condition (when 546 the data connection is not working properly, e.g., due to the STA 547 going outside the range of the AP). Disabled by default, enable by 548 config option disassoc_low_ack. 549 * Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad 550 config file. 551 * WPS: 552 - Send AP Settings as a wrapped Credential attribute to ctrl_iface 553 in WPS-NEW-AP-SETTINGS. 554 - Dispatch more WPS events through hostapd ctrl_iface. 555 - Add mechanism for indicating non-standard WPS errors. 556 - Change concurrent radio AP to use only one WPS UPnP instance. 557 - Add wps_check_pin command for processing PIN from user input. 558 UIs can use this command to process a PIN entered by a user and to 559 validate the checksum digit (if present). 560 - Add hostap_cli get_config command to display current AP config. 561 - Add new hostapd_cli command, wps_ap_pin, to manage AP PIN at 562 runtime and support dynamic AP PIN management. 563 - Disable AP PIN after 10 consecutive failures. Slow down attacks 564 on failures up to 10. 565 - Allow AP to start in Enrollee mode without AP PIN for probing, 566 to be compatible with Windows 7. 567 - Add Config Error into WPS-FAIL events to provide more info 568 to the user on how to resolve the issue. 569 - When controlling multiple interfaces: 570 - apply WPS commands to all interfaces configured to use WPS 571 - apply WPS config changes to all interfaces that use WPS 572 - when an attack is detected on any interface, disable AP PIN on 573 all interfaces 574 * WPS ER: 575 - Show SetSelectedRegistrar events as ctrl_iface events. 576 - Add special AP Setup Locked mode to allow read only ER. 577 ap_setup_locked=2 can now be used to enable a special mode where 578 WPS ER can learn the current AP settings, but cannot change them. 579 * WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2) 580 - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool 581 for testing protocol extensibility. 582 - Add build option CONFIG_WPS_STRICT to allow disabling of WPS 583 workarounds. 584 - Add support for AuthorizedMACs attribute. 585 * TDLS: 586 - Allow TDLS use or TDLS channel switching in the BSS to be 587 prohibited in the BSS, using config params tdls_prohibit and 588 tdls_prohibit_chan_switch. 589 * EAP server: Add support for configuring fragment size (see 590 fragment_size in hostapd.conf). 591 * wlantest: Add a tool wlantest for IEEE802.11 protocol testing. 592 wlantest can be used to capture frames from a monitor interface 593 for realtime capturing or from pcap files for offline analysis. 594 * Interworking: Support added for 802.11u. Enable in .config with 595 CONFIG_INTERWORKING. See hostapd.conf for config parameters for 596 interworking. 597 * Android: Add build and runtime support for Android hostapd. 598 * Add a new debug message level for excessive information. Use 599 -ddd to enable. 600 * TLS: Add support for tls_disable_time_checks=1 in client mode. 601 * Internal TLS: 602 - Add support for TLS v1.1 (RFC 4346). Enable with build parameter 603 CONFIG_TLSV11. 604 - Add domainComponent parser for X.509 names 605 * Reorder some IEs to get closer to IEEE 802.11 standard. Move 606 WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames. 607 Move HT IEs to be later in (Re)Assoc Resp. 608 * Many bugfixes. 609 6102010-04-18 - v0.7.2 611 * fix WPS internal Registrar use when an external Registrar is also 612 active 613 * bsd: Cleaned up driver wrapper and added various low-level 614 configuration options 615 * TNC: fixed issues with fragmentation 616 * EAP-TNC: add Flags field into fragment acknowledgement (needed to 617 interoperate with other implementations; may potentially breaks 618 compatibility with older wpa_supplicant/hostapd versions) 619 * cleaned up driver wrapper API for multi-BSS operations 620 * nl80211: fix multi-BSS and VLAN operations 621 * fix number of issues with IEEE 802.11r/FT; this version is not 622 backwards compatible with old versions 623 * add SA Query Request processing in AP mode (IEEE 802.11w) 624 * fix IGTK PN in group rekeying (IEEE 802.11w) 625 * fix WPS PBC session overlap detection to use correct attribute 626 * hostapd_notif_Assoc() can now be called with all IEs to simplify 627 driver wrappers 628 * work around interoperability issue with some WPS External Registrar 629 implementations 630 * nl80211: fix WPS IE update 631 * hostapd_cli: add support for action script operations (run a script 632 on hostapd events) 633 * fix DH padding with internal crypto code (mainly, for WPS) 634 * fix WPS association with both WPS IE and WPA/RSN IE present with 635 driver wrappers that use hostapd MLME (e.g., nl80211) 636 6372010-01-16 - v0.7.1 638 * cleaned up driver wrapper API (struct wpa_driver_ops); the new API 639 is not fully backwards compatible, so out-of-tree driver wrappers 640 will need modifications 641 * cleaned up various module interfaces 642 * merge hostapd and wpa_supplicant developers' documentation into a 643 single document 644 * fixed HT Capabilities IE with nl80211 drivers 645 * moved generic AP functionality code into src/ap 646 * WPS: handle Selected Registrar as union of info from all Registrars 647 * remove obsolte Prism54.org driver wrapper 648 * added internal debugging mechanism with backtrace support and memory 649 allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y) 650 * EAP-FAST server: piggyback Phase 2 start with the end of Phase 1 651 * WPS: add support for dynamically selecting whether to provision the 652 PSK as an ASCII passphrase or PSK 653 * added support for WDS (4-address frame) mode with per-station virtual 654 interfaces (wds_sta=1 in config file; only supported with 655 driver=nl80211 for now) 656 * fixed WPS Probe Request processing to handle missing required 657 attribute 658 * fixed PKCS#12 use with OpenSSL 1.0.0 659 * detect bridge interface automatically so that bridge parameter in 660 hostapd.conf becomes optional (though, it may now be used to 661 automatically add then WLAN interface into a bridge with 662 driver=nl80211) 663 6642009-11-21 - v0.7.0 665 * increased hostapd_cli ping interval to 5 seconds and made this 666 configurable with a new command line options (-G<seconds>) 667 * driver_nl80211: use Linux socket filter to improve performance 668 * added support for external Registrars with WPS (UPnP transport) 669 * 802.11n: scan for overlapping BSSes before starting 20/40 MHz channel 670 * driver_nl80211: fixed STA accounting data collection (TX/RX bytes 671 reported correctly; TX/RX packets not yet available from kernel) 672 * added support for WPS USBA out-of-band mechanism with USB Flash 673 Drives (UFD) (CONFIG_WPS_UFD=y) 674 * fixed EAPOL/EAP reauthentication when using an external RADIUS 675 authentication server 676 * fixed TNC with EAP-TTLS 677 * fixed IEEE 802.11r key derivation function to match with the standard 678 (note: this breaks interoperability with previous version) [Bug 303] 679 * fixed SHA-256 based key derivation function to match with the 680 standard when using CCMP (for IEEE 802.11r and IEEE 802.11w) 681 (note: this breaks interoperability with previous version) [Bug 307] 682 * added number of code size optimizations to remove unnecessary 683 functionality from the program binary based on build configuration 684 (part of this automatic; part configurable with CONFIG_NO_* build 685 options) 686 * use shared driver wrapper files with wpa_supplicant 687 * driver_nl80211: multiple updates to provide support for new Linux 688 nl80211/mac80211 functionality 689 * updated management frame protection to use IEEE Std 802.11w-2009 690 * fixed number of small WPS issues and added workarounds to 691 interoperate with common deployed broken implementations 692 * added some IEEE 802.11n co-existence rules to disable 40 MHz channels 693 or modify primary/secondary channels if needed based on neighboring 694 networks 695 * added support for NFC out-of-band mechanism with WPS 696 * added preliminary support for IEEE 802.11r RIC processing 697 6982009-01-06 - v0.6.7 699 * added support for Wi-Fi Protected Setup (WPS) 700 (hostapd can now be configured to act as an integrated WPS Registrar 701 and provision credentials for WPS Enrollees using PIN and PBC 702 methods; external wireless Registrar can configure the AP, but 703 external WLAN Manager Registrars are not supported); WPS support can 704 be enabled by adding CONFIG_WPS=y into .config and setting the 705 runtime configuration variables in hostapd.conf (see WPS section in 706 the example configuration file); new hostapd_cli commands wps_pin and 707 wps_pbc are used to configure WPS negotiation; see README-WPS for 708 more details 709 * added IEEE 802.11n HT capability configuration (ht_capab) 710 * added support for generating Country IE based on nl80211 regulatory 711 information (added if ieee80211d=1 in configuration) 712 * fixed WEP authentication (both Open System and Shared Key) with 713 mac80211 714 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf) 715 * added support for using driver_test over UDP socket 716 * changed EAP-GPSK to use the IANA assigned EAP method type 51 717 * updated management frame protection to use IEEE 802.11w/D7.0 718 * fixed retransmission of EAP requests if no response is received 719 7202008-11-23 - v0.6.6 721 * added a new configuration option, wpa_ptk_rekey, that can be used to 722 enforce frequent PTK rekeying, e.g., to mitigate some attacks against 723 TKIP deficiencies 724 * updated OpenSSL code for EAP-FAST to use an updated version of the 725 session ticket overriding API that was included into the upstream 726 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is 727 needed with that version anymore) 728 * changed channel flags configuration to read the information from 729 the driver (e.g., via driver_nl80211 when using mac80211) instead of 730 using hostapd as the source of the regulatory information (i.e., 731 information from CRDA is now used with mac80211); this allows 5 GHz 732 channels to be used with hostapd (if allowed in the current 733 regulatory domain) 734 * fixed EAP-TLS message processing for the last TLS message if it is 735 large enough to require fragmentation (e.g., if a large Session 736 Ticket data is included) 737 * fixed listen interval configuration for nl80211 drivers 738 7392008-11-01 - v0.6.5 740 * added support for SHA-256 as X.509 certificate digest when using the 741 internal X.509/TLSv1 implementation 742 * fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer 743 identity lengths) 744 * fixed internal TLSv1 implementation for abbreviated handshake (used 745 by EAP-FAST server) 746 * added support for setting VLAN ID for STAs based on local MAC ACL 747 (accept_mac_file) as an alternative for RADIUS server-based 748 configuration 749 * updated management frame protection to use IEEE 802.11w/D6.0 750 (adds a new association ping to protect against unauthenticated 751 authenticate or (re)associate request frames dropping association) 752 * added support for using SHA256-based stronger key derivation for WPA2 753 (IEEE 802.11w) 754 * added new "driver wrapper" for RADIUS-only configuration 755 (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config) 756 * fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2) 757 is enabled in configuration 758 * changed EAP-FAST configuration to use separate fields for A-ID and 759 A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed 760 16-octet len binary value for better interoperability with some peer 761 implementations; eap_fast_a_id is now configured as a hex string 762 * driver_nl80211: Updated to match the current Linux mac80211 AP mode 763 configuration (wireless-testing.git and Linux kernel releases 764 starting from 2.6.29) 765 7662008-08-10 - v0.6.4 767 * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2 768 Identity Request if identity is already known 769 * added support for EAP Sequences in EAP-FAST Phase 2 770 * added support for EAP-TNC (Trusted Network Connect) 771 (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST 772 changes needed to run two methods in sequence (IF-T) and the IF-IMV 773 and IF-TNCCS interfaces from TNCS) 774 * added support for optional cryptobinding with PEAPv0 775 * added fragmentation support for EAP-TNC 776 * added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled) 777 data 778 * added support for opportunistic key caching (OKC) 779 7802008-02-22 - v0.6.3 781 * fixed Reassociation Response callback processing when using internal 782 MLME (driver_{hostap,nl80211,test}.c) 783 * updated FT support to use the latest draft, IEEE 802.11r/D9.0 784 * copy optional Proxy-State attributes into RADIUS response when acting 785 as a RADIUS authentication server 786 * fixed EAPOL state machine to handle a case in which no response is 787 received from the RADIUS authentication server; previous version 788 could have triggered a crash in some cases after a timeout 789 * fixed EAP-SIM/AKA realm processing to allow decorated usernames to 790 be used 791 * added a workaround for EAP-SIM/AKA peers that include incorrect null 792 termination in the username 793 * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER 794 attribute in notification messages only when using fast 795 reauthentication 796 * fixed EAP-SIM Start response processing for fast reauthentication 797 case 798 * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST} 799 phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method 800 8012008-01-01 - v0.6.2 802 * fixed EAP-SIM and EAP-AKA message parser to validate attribute 803 lengths properly to avoid potential crash caused by invalid messages 804 * added data structure for storing allocated buffers (struct wpabuf); 805 this does not affect hostapd usage, but many of the APIs changed 806 and various interfaces (e.g., EAP) is not compatible with old 807 versions 808 * added support for protecting EAP-AKA/Identity messages with 809 AT_CHECKCODE (optional feature in RFC 4187) 810 * added support for protected result indication with AT_RESULT_IND for 811 EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1) 812 * added support for configuring EAP-TTLS phase 2 non-EAP methods in 813 EAP server configuration; previously all four were enabled for every 814 phase 2 user, now all four are disabled by default and need to be 815 enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP, 816 TTLS-MSCHAPV2 817 * removed old debug printing mechanism and the related 'debug' 818 parameter in the configuration file; debug verbosity is now set with 819 -d (or -dd) command line arguments 820 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt); 821 only shared key/password authentication is supported in this version 822 8232007-11-24 - v0.6.1 824 * added experimental, integrated TLSv1 server implementation with the 825 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by 826 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in 827 .config); this can be useful, e.g., if the target system does not 828 have a suitable TLS library and a minimal code size is required 829 * added support for EAP-FAST server method to the integrated EAP 830 server 831 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 832 draft (draft-ietf-emu-eap-gpsk-07.txt) 833 * added a new configuration parameter, rsn_pairwise, to allow different 834 pairwise cipher suites to be enabled for WPA and RSN/WPA2 835 (note: if wpa_pairwise differs from rsn_pairwise, the driver will 836 either need to support this or will have to use the WPA/RSN IEs from 837 hostapd; currently, the included madwifi and bsd driver interfaces do 838 not have support for this) 839 * updated FT support to use the latest draft, IEEE 802.11r/D8.0 840 8412007-05-28 - v0.6.0 842 * added experimental IEEE 802.11r/D6.0 support 843 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48 844 * updated EAP-PSK to use the IANA-allocated EAP type 47 845 * fixed EAP-PSK bit ordering of the Flags field 846 * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs 847 by reading wpa_psk_file [Bug 181] 848 * fixed EAP-TTLS AVP parser processing for too short AVP lengths 849 * fixed IPv6 connection to RADIUS accounting server 850 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 851 draft (draft-ietf-emu-eap-gpsk-04.txt) 852 * hlr_auc_gw: read GSM triplet file into memory and rotate through the 853 entries instead of only using the same three triplets every time 854 (this does not work properly with tests using multiple clients, but 855 provides bit better triplet data for testing a single client; anyway, 856 if a better quality triplets are needed, GSM-Milenage should be used 857 instead of hardcoded triplet file) 858 * fixed EAP-MSCHAPv2 server to use a space between S and M parameters 859 in Success Request [Bug 203] 860 * added support for sending EAP-AKA Notifications in error cases 861 * updated to use IEEE 802.11w/D2.0 for management frame protection 862 (still experimental) 863 * RADIUS server: added support for processing duplicate messages 864 (retransmissions from RADIUS client) by replying with the previous 865 reply 866 8672006-11-24 - v0.5.6 868 * added support for configuring and controlling multiple BSSes per 869 radio interface (bss=<ifname> in hostapd.conf); this is only 870 available with Devicescape and test driver interfaces 871 * fixed PMKSA cache update in the end of successful RSN 872 pre-authentication 873 * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID 874 for each STA based on RADIUS Access-Accept attributes); this requires 875 VLAN support from the kernel driver/802.11 stack and this is 876 currently only available with Devicescape and test driver interfaces 877 * driver_madwifi: fixed configuration of unencrypted modes (plaintext 878 and IEEE 802.1X without WEP) 879 * removed STAKey handshake since PeerKey handshake has replaced it in 880 IEEE 802.11ma and there are no known deployments of STAKey 881 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 882 draft (draft-ietf-emu-eap-gpsk-01.txt) 883 * added preliminary implementation of IEEE 802.11w/D1.0 (management 884 frame protection) 885 (Note: this requires driver support to work properly.) 886 (Note2: IEEE 802.11w is an unapproved draft and subject to change.) 887 * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM) 888 * hlr_auc_gw: added support for reading per-IMSI Milenage keys and 889 parameters from a text file to make it possible to implement proper 890 GSM/UMTS authentication server for multiple SIM/USIM cards using 891 EAP-SIM/EAP-AKA 892 * fixed session timeout processing with drivers that do not use 893 ieee802_11.c (e.g., madwifi) 894 8952006-08-27 - v0.5.5 896 * added 'hostapd_cli new_sta <addr>' command for adding a new STA into 897 hostapd (e.g., to initialize wired network authentication based on an 898 external signal) 899 * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when 900 using WPA2 even if PMKSA caching is not used 901 * added -P<pid file> argument for hostapd to write the current process 902 id into a file 903 * added support for RADIUS Authentication Server MIB (RFC 2619) 904 9052006-06-20 - v0.5.4 906 * fixed nt_password_hash build [Bug 144] 907 * added PeerKey handshake implementation for IEEE 802.11e 908 direct link setup (DLS) to replace STAKey handshake 909 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK, 910 draft-clancy-emu-eap-shared-secret-00.txt) 911 * fixed a segmentation fault when RSN pre-authentication was completed 912 successfully [Bug 152] 913 9142006-04-27 - v0.5.3 915 * do not build nt_password_hash and hlr_auc_gw by default to avoid 916 requiring a TLS library for a successful build; these programs can be 917 build with 'make nt_password_hash' and 'make hlr_auc_gw' 918 * added a new configuration option, eapol_version, that can be used to 919 set EAPOL version to 1 (default is 2) to work around broken client 920 implementations that drop EAPOL frames which use version number 2 921 [Bug 89] 922 * added support for EAP-SAKE (no EAP method number allocated yet, so 923 this is using the same experimental type 255 as EAP-PSK) 924 * fixed EAP-MSCHAPv2 message length validation 925 9262006-03-19 - v0.5.2 927 * fixed stdarg use in hostapd_logger(): if both stdout and syslog 928 logging was enabled, hostapd could trigger a segmentation fault in 929 vsyslog on some CPU -- C library combinations 930 * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external 931 program to make it easier to use for implementing real SS7 gateway; 932 eap_sim_db is not anymore used as a file name for GSM authentication 933 triplets; instead, it is path to UNIX domain socket that will be used 934 to communicate with the external gateway program (e.g., hlr_auc_gw) 935 * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses 936 local information (GSM authentication triplets from a text file and 937 hardcoded AKA authentication data); this can be used to test EAP-SIM 938 and EAP-AKA 939 * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw 940 to make it possible to test EAP-AKA with real USIM cards (this is 941 disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw 942 to enable this) 943 * driver_madwifi: added support for getting station RSN IE from 944 madwifi-ng svn r1453 and newer; this fixes RSN that was apparently 945 broken with earlier change (r1357) in the driver 946 * changed EAP method registration to use a dynamic list of methods 947 instead of a static list generated at build time 948 * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE) 949 [Bug 125] 950 * added ap_max_inactivity configuration parameter 951 9522006-01-29 - v0.5.1 953 * driver_test: added better support for multiple APs and STAs by using 954 a directory with sockets that include MAC address for each device in 955 the name (test_socket=DIR:/tmp/test) 956 * added support for EAP expanded type (vendor specific EAP methods) 957 9582005-12-18 - v0.5.0 (beginning of 0.5.x development releases) 959 * added experimental STAKey handshake implementation for IEEE 802.11e 960 direct link setup (DLS); note: this is disabled by default in both 961 build and runtime configuration (can be enabled with CONFIG_STAKEY=y 962 and stakey=1) 963 * added support for EAP methods to use callbacks to external programs 964 by buffering a pending request and processing it after the EAP method 965 is ready to continue 966 * improved EAP-SIM database interface to allow external request to GSM 967 HLR/AuC without blocking hostapd process 968 * added support for using EAP-SIM pseudonyms and fast re-authentication 969 * added support for EAP-AKA in the integrated EAP authenticator 970 * added support for matching EAP identity prefixes (e.g., "1"*) in EAP 971 user database to allow EAP-SIM/AKA selection without extra roundtrip 972 for EAP-Nak negotiation 973 * added support for storing EAP user password as NtPasswordHash instead 974 of plaintext password when using MSCHAP or MSCHAPv2 for 975 authentication (hash:<16-octet hex value>); added nt_password_hash 976 tool for hashing password to generate NtPasswordHash 977 9782005-11-20 - v0.4.7 (beginning of 0.4.x stable releases) 979 * driver_wired: fixed EAPOL sending to optionally use PAE group address 980 as the destination instead of supplicant MAC address; this is 981 disabled by default, but should be enabled with use_pae_group_addr=1 982 in configuration file if the wired interface is used by only one 983 device at the time (common switch configuration) 984 * driver_madwifi: configure driver to use TKIP countermeasures in order 985 to get correct behavior (IEEE 802.11 association failing; previously, 986 association succeeded, but hostpad forced disassociation immediately) 987 * driver_madwifi: added support for madwifi-ng 988 9892005-10-27 - v0.4.6 990 * added support for replacing user identity from EAP with RADIUS 991 User-Name attribute from Access-Accept message, if that is included, 992 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get 993 tunneled identity into accounting messages when the RADIUS server 994 does not support better way of doing this with Class attribute) 995 * driver_madwifi: fixed EAPOL packet receive for configuration where 996 ath# is part of a bridge interface 997 * added a configuration file and log analyzer script for logwatch 998 * fixed EAPOL state machine step function to process all state 999 transitions before processing new events; this resolves a race 1000 condition in which EAPOL-Start message could trigger hostapd to send 1001 two EAP-Response/Identity frames to the authentication server 1002 10032005-09-25 - v0.4.5 1004 * added client CA list to the TLS certificate request in order to make 1005 it easier for the client to select which certificate to use 1006 * added experimental support for EAP-PSK 1007 * added support for WE-19 (hostap, madwifi) 1008 10092005-08-21 - v0.4.4 1010 * fixed build without CONFIG_RSN_PREAUTH 1011 * fixed FreeBSD build 1012 10132005-06-26 - v0.4.3 1014 * fixed PMKSA caching to copy User-Name and Class attributes so that 1015 RADIUS accounting gets correct information 1016 * start RADIUS accounting only after successful completion of WPA 1017 4-Way Handshake if WPA-PSK is used 1018 * fixed PMKSA caching for the case where STA (re)associates without 1019 first disassociating 1020 10212005-06-12 - v0.4.2 1022 * EAP-PAX is now registered as EAP type 46 1023 * fixed EAP-PAX MAC calculation 1024 * fixed EAP-PAX CK and ICK key derivation 1025 * renamed eap_authenticator configuration variable to eap_server to 1026 better match with RFC 3748 (EAP) terminology 1027 * driver_test: added support for testing hostapd with wpa_supplicant 1028 by using test driver interface without any kernel drivers or network 1029 cards 1030 10312005-05-22 - v0.4.1 1032 * fixed RADIUS server initialization when only auth or acct server 1033 is configured and the other one is left empty 1034 * driver_madwifi: added support for RADIUS accounting 1035 * driver_madwifi: added preliminary support for compiling against 'BSD' 1036 branch of madwifi CVS tree 1037 * driver_madwifi: fixed pairwise key removal to allow WPA reauth 1038 without disassociation 1039 * added support for reading additional certificates from PKCS#12 files 1040 and adding them to the certificate chain 1041 * fixed RADIUS Class attribute processing to only use Access-Accept 1042 packets to update Class; previously, other RADIUS authentication 1043 packets could have cleared Class attribute 1044 * added support for more than one Class attribute in RADIUS packets 1045 * added support for verifying certificate revocation list (CRL) when 1046 using integrated EAP authenticator for EAP-TLS; new hostapd.conf 1047 options 'check_crl'; CRL must be included in the ca_cert file for now 1048 10492005-04-25 - v0.4.0 (beginning of 0.4.x development releases) 1050 * added support for including network information into 1051 EAP-Request/Identity message (ASCII-0 (nul) in eap_message) 1052 (e.g., to implement draft-adrange-eap-network-discovery-07.txt) 1053 * fixed a bug which caused some RSN pre-authentication cases to use 1054 freed memory and potentially crash hostapd 1055 * fixed private key loading for cases where passphrase is not set 1056 * added support for sending TLS alerts and aborting authentication 1057 when receiving a TLS alert 1058 * fixed WPA2 to add PMKSA cache entry when using integrated EAP 1059 authenticator 1060 * fixed PMKSA caching (EAP authentication was not skipped correctly 1061 with the new state machine changes from IEEE 802.1X draft) 1062 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr, 1063 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs 1064 to be added to .config to include IPv6 support); for RADIUS server, 1065 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses 1066 in RADIUS clients file can then use IPv6 format 1067 * added experimental support for EAP-PAX 1068 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with 1069 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch]) 1070 10712005-02-12 - v0.3.7 (beginning of 0.3.x stable releases) 1072 10732005-01-23 - v0.3.5 1074 * added support for configuring a forced PEAP version based on the 1075 Phase 1 identity 1076 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV 1077 to terminate authentication 1078 * fixed EAP identifier duplicate processing with the new IEEE 802.1X 1079 draft 1080 * clear accounting data in the driver when starting a new accounting 1081 session 1082 * driver_madwifi: filter wireless events based on ifindex to allow more 1083 than one network interface to be used 1084 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt 1085 setting if the packet does not pass MIC verification (e.g., due to 1086 incorrect PSK); previously, message 1/4 was not tried again if an 1087 invalid message 2/4 was received 1088 * fixed reconfiguration of RADIUS client retransmission timer when 1089 adding a new message to the pending list; previously, timer was not 1090 updated at this point and if there was a pending message with long 1091 time for the next retry, the new message needed to wait that long for 1092 its first retry, too 1093 10942005-01-09 - v0.3.4 1095 * added support for configuring multiple allowed EAP types for Phase 2 1096 authentication (EAP-PEAP, EAP-TTLS) 1097 * fixed EAPOL-Start processing to trigger WPA reauthentication 1098 (previously, only EAPOL authentication was done) 1099 11002005-01-02 - v0.3.3 1101 * added support for EAP-PEAP in the integrated EAP authenticator 1102 * added support for EAP-GTC in the integrated EAP authenticator 1103 * added support for configuring list of EAP methods for Phase 1 so that 1104 the integrated EAP authenticator can, e.g., use the wildcard entry 1105 for EAP-TLS and EAP-PEAP 1106 * added support for EAP-TTLS in the integrated EAP authenticator 1107 * added support for EAP-SIM in the integrated EAP authenticator 1108 * added support for using hostapd as a RADIUS authentication server 1109 with the integrated EAP authenticator taking care of EAP 1110 authentication (new hostapd.conf options: radius_server_clients and 1111 radius_server_auth_port); this is not included in default build; use 1112 CONFIG_RADIUS_SERVER=y in .config to include 1113 11142004-12-19 - v0.3.2 1115 * removed 'daemonize' configuration file option since it has not really 1116 been used at all for more than year 1117 * driver_madwifi: fixed group key setup and added get_ssid method 1118 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator 1119 11202004-12-12 - v0.3.1 1121 * added support for integrated EAP-TLS authentication (new hostapd.conf 1122 variables: ca_cert, server_cert, private_key, private_key_passwd); 1123 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without 1124 external RADIUS server 1125 * added support for reading PKCS#12 (PFX) files (as a replacement for 1126 PEM/DER) to get certificate and private key (CONFIG_PKCS12) 1127 11282004-12-05 - v0.3.0 (beginning of 0.3.x development releases) 1129 * added support for Acct-{Input,Output}-Gigawords 1130 * added support for Event-Timestamp (in RADIUS Accounting-Requests) 1131 * added support for RADIUS Authentication Client MIB (RFC2618) 1132 * added support for RADIUS Accounting Client MIB (RFC2620) 1133 * made EAP re-authentication period configurable (eap_reauth_period) 1134 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication 1135 * fixed EAPOL state machine to stop if STA is removed during 1136 eapol_sm_step(); this fixes at least one segfault triggering bug with 1137 IEEE 802.11i pre-authentication 1138 * added support for multiple WPA pre-shared keys (e.g., one for each 1139 client MAC address or keys shared by a group of clients); 1140 new hostapd.conf field wpa_psk_file for setting path to a text file 1141 containing PSKs, see hostapd.wpa_psk for an example 1142 * added support for multiple driver interfaces to allow hostapd to be 1143 used with other drivers 1144 * added wired authenticator driver interface (driver=wired in 1145 hostapd.conf, see wired.conf for example configuration) 1146 * added madwifi driver interface (driver=madwifi in hostapd.conf, see 1147 madwifi.conf for example configuration; Note: include files from 1148 madwifi project is needed for building and a configuration file, 1149 .config, needs to be created in hostapd directory with 1150 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd 1151 build) 1152 * fixed an alignment issue that could cause SHA-1 to fail on some 1153 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit 1154 align variables) 1155 * fixed RADIUS reconnection after an error in sending interim 1156 accounting packets 1157 * added hostapd control interface for external programs and an example 1158 CLI, hostapd_cli (like wpa_cli for wpa_supplicant) 1159 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib', 1160 'hostapd_cli sta <addr>') 1161 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11) 1162 * added support for strict GTK rekeying (wpa_strict_rekey in 1163 hostapd.conf) 1164 * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178 1165 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to 1166 IEEE 802.11F-2003) 1167 * added Prism54 driver interface (driver=prism54 in hostapd.conf; 1168 note: .config needs to be created in hostapd directory with 1169 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd 1170 build) 1171 * dual-licensed hostapd (GPLv2 and BSD licenses) 1172 * fixed RADIUS accounting to generate a new session id for cases where 1173 a station reassociates without first being complete deauthenticated 1174 * fixed STA disassociation handler to mark next timeout state to 1175 deauthenticate the station, i.e., skip long wait for inactivity poll 1176 and extra disassociation, if the STA disassociates without 1177 deauthenticating 1178 * added integrated EAP authenticator that can be used instead of 1179 external RADIUS authentication server; currently, only EAP-MD5 is 1180 supported, so this cannot yet be used for key distribution; the EAP 1181 method interface is generic, though, so adding new EAP methods should 1182 be straightforward; new hostapd.conf variables: 'eap_authenticator' 1183 and 'eap_user_file'; this obsoletes "minimal authentication server" 1184 ('minimal_eap' in hostapd.conf) which is now removed 1185 * added support for FreeBSD and driver interface for the BSD net80211 1186 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in 1187 .config); please note that some of the required kernel mods have not 1188 yet been committed 1189 11902004-07-17 - v0.2.4 (beginning of 0.2.x stable releases) 1191 * fixed some accounting cases where Accounting-Start was sent when 1192 IEEE 802.1X port was being deauthorized 1193 11942004-06-20 - v0.2.3 1195 * modified RADIUS client to re-connect the socket in case of certain 1196 error codes that are generated when a network interface state is 1197 changes (e.g., when IP address changes or the interface is set UP) 1198 * fixed couple of cases where EAPOL state for a station was freed 1199 twice causing a segfault for hostapd 1200 * fixed couple of bugs in processing WPA deauthentication (freed data 1201 was used) 1202 12032004-05-31 - v0.2.2 1204 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM) 1205 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix 1206 cases where STAs dropped multicast frames as replay attacks 1207 * added support for copying RADIUS Attribute 'Class' from 1208 authentication messages into accounting messages 1209 * send canned EAP failure if RADIUS server sends Access-Reject without 1210 EAP message (previously, Supplicant was not notified in this case) 1211 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do 1212 not start EAPOL state machines if the STA selected to use WPA-PSK) 1213 12142004-05-06 - v0.2.1 1215 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality 1216 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA 1217 (i.e., IEEE 802.11i/D3.0) 1218 - supports WPA-only, RSN-only, and mixed WPA/RSN mode 1219 - both WPA-PSK and WPA-RADIUS/EAP are supported 1220 - PMKSA caching and pre-authentication 1221 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase, 1222 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey, 1223 rsn_preauth, rsn_preauth_interfaces 1224 * fixed interim accounting to remove any pending accounting messages 1225 to the STA before sending a new one 1226 12272004-02-15 - v0.2.0 1228 * added support for Acct-Interim-Interval: 1229 - draft-ietf-radius-acct-interim-01.txt 1230 - use Acct-Interim-Interval attribute from Access-Accept if local 1231 'radius_acct_interim_interval' is not set 1232 - allow different update intervals for each STA 1233 * fixed event loop to call signal handlers only after returning from 1234 the real signal handler 1235 * reset sta->timeout_next after successful association to make sure 1236 that the previously registered inactivity timer will not remove the 1237 STA immediately (e.g., if STA deauthenticates and re-associates 1238 before the timer is triggered). 1239 * added new hostapd.conf variable, nas_identifier, that can be used to 1240 add an optional RADIUS Attribute, NAS-Identifier, into authentication 1241 and accounting messages 1242 * added support for Accounting-On and Accounting-Off messages 1243 * fixed accounting session handling to send Accounting-Start only once 1244 per session and not to send Accounting-Stop if the session was not 1245 initialized properly 1246 * fixed Accounting-Stop statistics in cases where the message was 1247 previously sent after the kernel entry for the STA (and/or IEEE 1248 802.1X data) was removed 1249 1250 1251Note: 1252 1253Older changes up to and including v0.1.0 are included in the ChangeLog 1254of the Host AP driver. 1255
