It works in the same way as new AP settings received 484 from an ER. 485 - Many WPS/WPS ER commands - see WPS/WPS ER sections for details. 486 - Add command get version, that returns hostapd version string. 487 * WNM: Add BSS Transition Management Request for ESS Disassoc Imminent. 488 Use hostapd_cli ess_disassoc (STA addr) (URL) to send the 489 notification to the STA. 490 * Allow AP mode to disconnect STAs based on low ACK condition (when 491 the data connection is not working properly, e.g., due to the STA 492 going outside the range of the AP). Disabled by default, enable by 493 config option disassoc_low_ack. 494 * Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad 495 config file. 496 * WPS: 497 - Send AP Settings as a wrapped Credential attribute to ctrl_iface 498 in WPS-NEW-AP-SETTINGS. 499 - Dispatch more WPS events through hostapd ctrl_iface. 500 - Add mechanism for indicating non-standard WPS errors. 501 - Change concurrent radio AP to use only one WPS UPnP instance. 502 - Add wps_check_pin command for processing PIN from user input. 503 UIs can use this command to process a PIN entered by a user and to 504 validate the checksum digit (if present). 505 - Add hostap_cli get_config command to display current AP config. 506 - Add new hostapd_cli command, wps_ap_pin, to manage AP PIN at 507 runtime and support dynamic AP PIN management. 508 - Disable AP PIN after 10 consecutive failures. Slow down attacks 509 on failures up to 10. 510 - Allow AP to start in Enrollee mode without AP PIN for probing, 511 to be compatible with Windows 7. 512 - Add Config Error into WPS-FAIL events to provide more info 513 to the user on how to resolve the issue. 514 - When controlling multiple interfaces: 515 - apply WPS commands to all interfaces configured to use WPS 516 - apply WPS config changes to all interfaces that use WPS 517 - when an attack is detected on any interface, disable AP PIN on 518 all interfaces 519 * WPS ER: 520 - Show SetSelectedRegistrar events as ctrl_iface events. 521 - Add special AP Setup Locked mode to allow read only ER. 522 ap_setup_locked=2 can now be used to enable a special mode where 523 WPS ER can learn the current AP settings, but cannot change them. 524 * WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2) 525 - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool 526 for testing protocol extensibility. 527 - Add build option CONFIG_WPS_STRICT to allow disabling of WPS 528 workarounds. 529 - Add support for AuthorizedMACs attribute. 530 * TDLS: 531 - Allow TDLS use or TDLS channel switching in the BSS to be 532 prohibited in the BSS, using config params tdls_prohibit and 533 tdls_prohibit_chan_switch. 534 * EAP server: Add support for configuring fragment size (see 535 fragment_size in hostapd.conf). 536 * wlantest: Add a tool wlantest for IEEE802.11 protocol testing. 537 wlantest can be used to capture frames from a monitor interface 538 for realtime capturing or from pcap files for offline analysis. 539 * Interworking: Support added for 802.11u. Enable in .config with 540 CONFIG_INTERWORKING. See hostapd.conf for config parameters for 541 interworking. 542 * Android: Add build and runtime support for Android hostapd. 543 * Add a new debug message level for excessive information. Use 544 -ddd to enable. 545 * TLS: Add support for tls_disable_time_checks=1 in client mode. 546 * Internal TLS: 547 - Add support for TLS v1.1 (RFC 4346). Enable with build parameter 548 CONFIG_TLSV11. 549 - Add domainComponent parser for X.509 names 550 * Reorder some IEs to get closer to IEEE 802.11 standard. Move 551 WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames. 552 Move HT IEs to be later in (Re)Assoc Resp. 553 * Many bugfixes. 554 5552010-04-18 - v0.7.2 556 * fix WPS internal Registrar use when an external Registrar is also 557 active 558 * bsd: Cleaned up driver wrapper and added various low-level 559 configuration options 560 * TNC: fixed issues with fragmentation 561 * EAP-TNC: add Flags field into fragment acknowledgement (needed to 562 interoperate with other implementations; may potentially breaks 563 compatibility with older wpa_supplicant/hostapd versions) 564 * cleaned up driver wrapper API for multi-BSS operations 565 * nl80211: fix multi-BSS and VLAN operations 566 * fix number of issues with IEEE 802.11r/FT; this version is not 567 backwards compatible with old versions 568 * add SA Query Request processing in AP mode (IEEE 802.11w) 569 * fix IGTK PN in group rekeying (IEEE 802.11w) 570 * fix WPS PBC session overlap detection to use correct attribute 571 * hostapd_notif_Assoc() can now be called with all IEs to simplify 572 driver wrappers 573 * work around interoperability issue with some WPS External Registrar 574 implementations 575 * nl80211: fix WPS IE update 576 * hostapd_cli: add support for action script operations (run a script 577 on hostapd events) 578 * fix DH padding with internal crypto code (mainly, for WPS) 579 * fix WPS association with both WPS IE and WPA/RSN IE present with 580 driver wrappers that use hostapd MLME (e.g., nl80211) 581 5822010-01-16 - v0.7.1 583 * cleaned up driver wrapper API (struct wpa_driver_ops); the new API 584 is not fully backwards compatible, so out-of-tree driver wrappers 585 will need modifications 586 * cleaned up various module interfaces 587 * merge hostapd and wpa_supplicant developers' documentation into a 588 single document 589 * fixed HT Capabilities IE with nl80211 drivers 590 * moved generic AP functionality code into src/ap 591 * WPS: handle Selected Registrar as union of info from all Registrars 592 * remove obsolte Prism54.org driver wrapper 593 * added internal debugging mechanism with backtrace support and memory 594 allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y) 595 * EAP-FAST server: piggyback Phase 2 start with the end of Phase 1 596 * WPS: add support for dynamically selecting whether to provision the 597 PSK as an ASCII passphrase or PSK 598 * added support for WDS (4-address frame) mode with per-station virtual 599 interfaces (wds_sta=1 in config file; only supported with 600 driver=nl80211 for now) 601 * fixed WPS Probe Request processing to handle missing required 602 attribute 603 * fixed PKCS#12 use with OpenSSL 1.0.0 604 * detect bridge interface automatically so that bridge parameter in 605 hostapd.conf becomes optional (though, it may now be used to 606 automatically add then WLAN interface into a bridge with 607 driver=nl80211) 608 6092009-11-21 - v0.7.0 610 * increased hostapd_cli ping interval to 5 seconds and made this 611 configurable with a new command line options (-G<seconds>) 612 * driver_nl80211: use Linux socket filter to improve performance 613 * added support for external Registrars with WPS (UPnP transport) 614 * 802.11n: scan for overlapping BSSes before starting 20/40 MHz channel 615 * driver_nl80211: fixed STA accounting data collection (TX/RX bytes 616 reported correctly; TX/RX packets not yet available from kernel) 617 * added support for WPS USBA out-of-band mechanism with USB Flash 618 Drives (UFD) (CONFIG_WPS_UFD=y) 619 * fixed EAPOL/EAP reauthentication when using an external RADIUS 620 authentication server 621 * fixed TNC with EAP-TTLS 622 * fixed IEEE 802.11r key derivation function to match with the standard 623 (note: this breaks interoperability with previous version) [Bug 303] 624 * fixed SHA-256 based key derivation function to match with the 625 standard when using CCMP (for IEEE 802.11r and IEEE 802.11w) 626 (note: this breaks interoperability with previous version) [Bug 307] 627 * added number of code size optimizations to remove unnecessary 628 functionality from the program binary based on build configuration 629 (part of this automatic; part configurable with CONFIG_NO_* build 630 options) 631 * use shared driver wrapper files with wpa_supplicant 632 * driver_nl80211: multiple updates to provide support for new Linux 633 nl80211/mac80211 functionality 634 * updated management frame protection to use IEEE Std 802.11w-2009 635 * fixed number of small WPS issues and added workarounds to 636 interoperate with common deployed broken implementations 637 * added some IEEE 802.11n co-existence rules to disable 40 MHz channels 638 or modify primary/secondary channels if needed based on neighboring 639 networks 640 * added support for NFC out-of-band mechanism with WPS 641 * added preliminary support for IEEE 802.11r RIC processing 642 6432009-01-06 - v0.6.7 644 * added support for Wi-Fi Protected Setup (WPS) 645 (hostapd can now be configured to act as an integrated WPS Registrar 646 and provision credentials for WPS Enrollees using PIN and PBC 647 methods; external wireless Registrar can configure the AP, but 648 external WLAN Manager Registrars are not supported); WPS support can 649 be enabled by adding CONFIG_WPS=y into .config and setting the 650 runtime configuration variables in hostapd.conf (see WPS section in 651 the example configuration file); new hostapd_cli commands wps_pin and 652 wps_pbc are used to configure WPS negotiation; see README-WPS for 653 more details 654 * added IEEE 802.11n HT capability configuration (ht_capab) 655 * added support for generating Country IE based on nl80211 regulatory 656 information (added if ieee80211d=1 in configuration) 657 * fixed WEP authentication (both Open System and Shared Key) with 658 mac80211 659 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf) 660 * added support for using driver_test over UDP socket 661 * changed EAP-GPSK to use the IANA assigned EAP method type 51 662 * updated management frame protection to use IEEE 802.11w/D7.0 663 * fixed retransmission of EAP requests if no response is received 664 6652008-11-23 - v0.6.6 666 * added a new configuration option, wpa_ptk_rekey, that can be used to 667 enforce frequent PTK rekeying, e.g., to mitigate some attacks against 668 TKIP deficiencies 669 * updated OpenSSL code for EAP-FAST to use an updated version of the 670 session ticket overriding API that was included into the upstream 671 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is 672 needed with that version anymore) 673 * changed channel flags configuration to read the information from 674 the driver (e.g., via driver_nl80211 when using mac80211) instead of 675 using hostapd as the source of the regulatory information (i.e., 676 information from CRDA is now used with mac80211); this allows 5 GHz 677 channels to be used with hostapd (if allowed in the current 678 regulatory domain) 679 * fixed EAP-TLS message processing for the last TLS message if it is 680 large enough to require fragmentation (e.g., if a large Session 681 Ticket data is included) 682 * fixed listen interval configuration for nl80211 drivers 683 6842008-11-01 - v0.6.5 685 * added support for SHA-256 as X.509 certificate digest when using the 686 internal X.509/TLSv1 implementation 687 * fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer 688 identity lengths) 689 * fixed internal TLSv1 implementation for abbreviated handshake (used 690 by EAP-FAST server) 691 * added support for setting VLAN ID for STAs based on local MAC ACL 692 (accept_mac_file) as an alternative for RADIUS server-based 693 configuration 694 * updated management frame protection to use IEEE 802.11w/D6.0 695 (adds a new association ping to protect against unauthenticated 696 authenticate or (re)associate request frames dropping association) 697 * added support for using SHA256-based stronger key derivation for WPA2 698 (IEEE 802.11w) 699 * added new "driver wrapper" for RADIUS-only configuration 700 (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config) 701 * fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2) 702 is enabled in configuration 703 * changed EAP-FAST configuration to use separate fields for A-ID and 704 A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed 705 16-octet len binary value for better interoperability with some peer 706 implementations; eap_fast_a_id is now configured as a hex string 707 * driver_nl80211: Updated to match the current Linux mac80211 AP mode 708 configuration (wireless-testing.git and Linux kernel releases 709 starting from 2.6.29) 710 7112008-08-10 - v0.6.4 712 * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2 713 Identity Request if identity is already known 714 * added support for EAP Sequences in EAP-FAST Phase 2 715 * added support for EAP-TNC (Trusted Network Connect) 716 (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST 717 changes needed to run two methods in sequence (IF-T) and the IF-IMV 718 and IF-TNCCS interfaces from TNCS) 719 * added support for optional cryptobinding with PEAPv0 720 * added fragmentation support for EAP-TNC 721 * added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled) 722 data 723 * added support for opportunistic key caching (OKC) 724 7252008-02-22 - v0.6.3 726 * fixed Reassociation Response callback processing when using internal 727 MLME (driver_{hostap,nl80211,test}.c) 728 * updated FT support to use the latest draft, IEEE 802.11r/D9.0 729 * copy optional Proxy-State attributes into RADIUS response when acting 730 as a RADIUS authentication server 731 * fixed EAPOL state machine to handle a case in which no response is 732 received from the RADIUS authentication server; previous version 733 could have triggered a crash in some cases after a timeout 734 * fixed EAP-SIM/AKA realm processing to allow decorated usernames to 735 be used 736 * added a workaround for EAP-SIM/AKA peers that include incorrect null 737 termination in the username 738 * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER 739 attribute in notification messages only when using fast 740 reauthentication 741 * fixed EAP-SIM Start response processing for fast reauthentication 742 case 743 * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST} 744 phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method 745 7462008-01-01 - v0.6.2 747 * fixed EAP-SIM and EAP-AKA message parser to validate attribute 748 lengths properly to avoid potential crash caused by invalid messages 749 * added data structure for storing allocated buffers (struct wpabuf); 750 this does not affect hostapd usage, but many of the APIs changed 751 and various interfaces (e.g., EAP) is not compatible with old 752 versions 753 * added support for protecting EAP-AKA/Identity messages with 754 AT_CHECKCODE (optional feature in RFC 4187) 755 * added support for protected result indication with AT_RESULT_IND for 756 EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1) 757 * added support for configuring EAP-TTLS phase 2 non-EAP methods in 758 EAP server configuration; previously all four were enabled for every 759 phase 2 user, now all four are disabled by default and need to be 760 enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP, 761 TTLS-MSCHAPV2 762 * removed old debug printing mechanism and the related 'debug' 763 parameter in the configuration file; debug verbosity is now set with 764 -d (or -dd) command line arguments 765 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt); 766 only shared key/password authentication is supported in this version 767 7682007-11-24 - v0.6.1 769 * added experimental, integrated TLSv1 server implementation with the 770 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by 771 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in 772 .config); this can be useful, e.g., if the target system does not 773 have a suitable TLS library and a minimal code size is required 774 * added support for EAP-FAST server method to the integrated EAP 775 server 776 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 777 draft (draft-ietf-emu-eap-gpsk-07.txt) 778 * added a new configuration parameter, rsn_pairwise, to allow different 779 pairwise cipher suites to be enabled for WPA and RSN/WPA2 780 (note: if wpa_pairwise differs from rsn_pairwise, the driver will 781 either need to support this or will have to use the WPA/RSN IEs from 782 hostapd; currently, the included madwifi and bsd driver interfaces do 783 not have support for this) 784 * updated FT support to use the latest draft, IEEE 802.11r/D8.0 785 7862007-05-28 - v0.6.0 787 * added experimental IEEE 802.11r/D6.0 support 788 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48 789 * updated EAP-PSK to use the IANA-allocated EAP type 47 790 * fixed EAP-PSK bit ordering of the Flags field 791 * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs 792 by reading wpa_psk_file [Bug 181] 793 * fixed EAP-TTLS AVP parser processing for too short AVP lengths 794 * fixed IPv6 connection to RADIUS accounting server 795 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 796 draft (draft-ietf-emu-eap-gpsk-04.txt) 797 * hlr_auc_gw: read GSM triplet file into memory and rotate through the 798 entries instead of only using the same three triplets every time 799 (this does not work properly with tests using multiple clients, but 800 provides bit better triplet data for testing a single client; anyway, 801 if a better quality triplets are needed, GSM-Milenage should be used 802 instead of hardcoded triplet file) 803 * fixed EAP-MSCHAPv2 server to use a space between S and M parameters 804 in Success Request [Bug 203] 805 * added support for sending EAP-AKA Notifications in error cases 806 * updated to use IEEE 802.11w/D2.0 for management frame protection 807 (still experimental) 808 * RADIUS server: added support for processing duplicate messages 809 (retransmissions from RADIUS client) by replying with the previous 810 reply 811 8122006-11-24 - v0.5.6 813 * added support for configuring and controlling multiple BSSes per 814 radio interface (bss=<ifname> in hostapd.conf); this is only 815 available with Devicescape and test driver interfaces 816 * fixed PMKSA cache update in the end of successful RSN 817 pre-authentication 818 * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID 819 for each STA based on RADIUS Access-Accept attributes); this requires 820 VLAN support from the kernel driver/802.11 stack and this is 821 currently only available with Devicescape and test driver interfaces 822 * driver_madwifi: fixed configuration of unencrypted modes (plaintext 823 and IEEE 802.1X without WEP) 824 * removed STAKey handshake since PeerKey handshake has replaced it in 825 IEEE 802.11ma and there are no known deployments of STAKey 826 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 827 draft (draft-ietf-emu-eap-gpsk-01.txt) 828 * added preliminary implementation of IEEE 802.11w/D1.0 (management 829 frame protection) 830 (Note: this requires driver support to work properly.) 831 (Note2: IEEE 802.11w is an unapproved draft and subject to change.) 832 * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM) 833 * hlr_auc_gw: added support for reading per-IMSI Milenage keys and 834 parameters from a text file to make it possible to implement proper 835 GSM/UMTS authentication server for multiple SIM/USIM cards using 836 EAP-SIM/EAP-AKA 837 * fixed session timeout processing with drivers that do not use 838 ieee802_11.c (e.g., madwifi) 839 8402006-08-27 - v0.5.5 841 * added 'hostapd_cli new_sta <addr>' command for adding a new STA into 842 hostapd (e.g., to initialize wired network authentication based on an 843 external signal) 844 * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when 845 using WPA2 even if PMKSA caching is not used 846 * added -P<pid file> argument for hostapd to write the current process 847 id into a file 848 * added support for RADIUS Authentication Server MIB (RFC 2619) 849 8502006-06-20 - v0.5.4 851 * fixed nt_password_hash build [Bug 144] 852 * added PeerKey handshake implementation for IEEE 802.11e 853 direct link setup (DLS) to replace STAKey handshake 854 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK, 855 draft-clancy-emu-eap-shared-secret-00.txt) 856 * fixed a segmentation fault when RSN pre-authentication was completed 857 successfully [Bug 152] 858 8592006-04-27 - v0.5.3 860 * do not build nt_password_hash and hlr_auc_gw by default to avoid 861 requiring a TLS library for a successful build; these programs can be 862 build with 'make nt_password_hash' and 'make hlr_auc_gw' 863 * added a new configuration option, eapol_version, that can be used to 864 set EAPOL version to 1 (default is 2) to work around broken client 865 implementations that drop EAPOL frames which use version number 2 866 [Bug 89] 867 * added support for EAP-SAKE (no EAP method number allocated yet, so 868 this is using the same experimental type 255 as EAP-PSK) 869 * fixed EAP-MSCHAPv2 message length validation 870 8712006-03-19 - v0.5.2 872 * fixed stdarg use in hostapd_logger(): if both stdout and syslog 873 logging was enabled, hostapd could trigger a segmentation fault in 874 vsyslog on some CPU -- C library combinations 875 * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external 876 program to make it easier to use for implementing real SS7 gateway; 877 eap_sim_db is not anymore used as a file name for GSM authentication 878 triplets; instead, it is path to UNIX domain socket that will be used 879 to communicate with the external gateway program (e.g., hlr_auc_gw) 880 * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses 881 local information (GSM authentication triplets from a text file and 882 hardcoded AKA authentication data); this can be used to test EAP-SIM 883 and EAP-AKA 884 * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw 885 to make it possible to test EAP-AKA with real USIM cards (this is 886 disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw 887 to enable this) 888 * driver_madwifi: added support for getting station RSN IE from 889 madwifi-ng svn r1453 and newer; this fixes RSN that was apparently 890 broken with earlier change (r1357) in the driver 891 * changed EAP method registration to use a dynamic list of methods 892 instead of a static list generated at build time 893 * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE) 894 [Bug 125] 895 * added ap_max_inactivity configuration parameter 896 8972006-01-29 - v0.5.1 898 * driver_test: added better support for multiple APs and STAs by using 899 a directory with sockets that include MAC address for each device in 900 the name (test_socket=DIR:/tmp/test) 901 * added support for EAP expanded type (vendor specific EAP methods) 902 9032005-12-18 - v0.5.0 (beginning of 0.5.x development releases) 904 * added experimental STAKey handshake implementation for IEEE 802.11e 905 direct link setup (DLS); note: this is disabled by default in both 906 build and runtime configuration (can be enabled with CONFIG_STAKEY=y 907 and stakey=1) 908 * added support for EAP methods to use callbacks to external programs 909 by buffering a pending request and processing it after the EAP method 910 is ready to continue 911 * improved EAP-SIM database interface to allow external request to GSM 912 HLR/AuC without blocking hostapd process 913 * added support for using EAP-SIM pseudonyms and fast re-authentication 914 * added support for EAP-AKA in the integrated EAP authenticator 915 * added support for matching EAP identity prefixes (e.g., "1"*) in EAP 916 user database to allow EAP-SIM/AKA selection without extra roundtrip 917 for EAP-Nak negotiation 918 * added support for storing EAP user password as NtPasswordHash instead 919 of plaintext password when using MSCHAP or MSCHAPv2 for 920 authentication (hash:<16-octet hex value>); added nt_password_hash 921 tool for hashing password to generate NtPasswordHash 922 9232005-11-20 - v0.4.7 (beginning of 0.4.x stable releases) 924 * driver_wired: fixed EAPOL sending to optionally use PAE group address 925 as the destination instead of supplicant MAC address; this is 926 disabled by default, but should be enabled with use_pae_group_addr=1 927 in configuration file if the wired interface is used by only one 928 device at the time (common switch configuration) 929 * driver_madwifi: configure driver to use TKIP countermeasures in order 930 to get correct behavior (IEEE 802.11 association failing; previously, 931 association succeeded, but hostpad forced disassociation immediately) 932 * driver_madwifi: added support for madwifi-ng 933 9342005-10-27 - v0.4.6 935 * added support for replacing user identity from EAP with RADIUS 936 User-Name attribute from Access-Accept message, if that is included, 937 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get 938 tunneled identity into accounting messages when the RADIUS server 939 does not support better way of doing this with Class attribute) 940 * driver_madwifi: fixed EAPOL packet receive for configuration where 941 ath# is part of a bridge interface 942 * added a configuration file and log analyzer script for logwatch 943 * fixed EAPOL state machine step function to process all state 944 transitions before processing new events; this resolves a race 945 condition in which EAPOL-Start message could trigger hostapd to send 946 two EAP-Response/Identity frames to the authentication server 947 9482005-09-25 - v0.4.5 949 * added client CA list to the TLS certificate request in order to make 950 it easier for the client to select which certificate to use 951 * added experimental support for EAP-PSK 952 * added support for WE-19 (hostap, madwifi) 953 9542005-08-21 - v0.4.4 955 * fixed build without CONFIG_RSN_PREAUTH 956 * fixed FreeBSD build 957 9582005-06-26 - v0.4.3 959 * fixed PMKSA caching to copy User-Name and Class attributes so that 960 RADIUS accounting gets correct information 961 * start RADIUS accounting only after successful completion of WPA 962 4-Way Handshake if WPA-PSK is used 963 * fixed PMKSA caching for the case where STA (re)associates without 964 first disassociating 965 9662005-06-12 - v0.4.2 967 * EAP-PAX is now registered as EAP type 46 968 * fixed EAP-PAX MAC calculation 969 * fixed EAP-PAX CK and ICK key derivation 970 * renamed eap_authenticator configuration variable to eap_server to 971 better match with RFC 3748 (EAP) terminology 972 * driver_test: added support for testing hostapd with wpa_supplicant 973 by using test driver interface without any kernel drivers or network 974 cards 975 9762005-05-22 - v0.4.1 977 * fixed RADIUS server initialization when only auth or acct server 978 is configured and the other one is left empty 979 * driver_madwifi: added support for RADIUS accounting 980 * driver_madwifi: added preliminary support for compiling against 'BSD' 981 branch of madwifi CVS tree 982 * driver_madwifi: fixed pairwise key removal to allow WPA reauth 983 without disassociation 984 * added support for reading additional certificates from PKCS#12 files 985 and adding them to the certificate chain 986 * fixed RADIUS Class attribute processing to only use Access-Accept 987 packets to update Class; previously, other RADIUS authentication 988 packets could have cleared Class attribute 989 * added support for more than one Class attribute in RADIUS packets 990 * added support for verifying certificate revocation list (CRL) when 991 using integrated EAP authenticator for EAP-TLS; new hostapd.conf 992 options 'check_crl'; CRL must be included in the ca_cert file for now 993 9942005-04-25 - v0.4.0 (beginning of 0.4.x development releases) 995 * added support for including network information into 996 EAP-Request/Identity message (ASCII-0 (nul) in eap_message) 997 (e.g., to implement draft-adrange-eap-network-discovery-07.txt) 998 * fixed a bug which caused some RSN pre-authentication cases to use 999 freed memory and potentially crash hostapd 1000 * fixed private key loading for cases where passphrase is not set 1001 * added support for sending TLS alerts and aborting authentication 1002 when receiving a TLS alert 1003 * fixed WPA2 to add PMKSA cache entry when using integrated EAP 1004 authenticator 1005 * fixed PMKSA caching (EAP authentication was not skipped correctly 1006 with the new state machine changes from IEEE 802.1X draft) 1007 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr, 1008 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs 1009 to be added to .config to include IPv6 support); for RADIUS server, 1010 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses 1011 in RADIUS clients file can then use IPv6 format 1012 * added experimental support for EAP-PAX 1013 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with 1014 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch]) 1015 10162005-02-12 - v0.3.7 (beginning of 0.3.x stable releases) 1017 10182005-01-23 - v0.3.5 1019 * added support for configuring a forced PEAP version based on the 1020 Phase 1 identity 1021 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV 1022 to terminate authentication 1023 * fixed EAP identifier duplicate processing with the new IEEE 802.1X 1024 draft 1025 * clear accounting data in the driver when starting a new accounting 1026 session 1027 * driver_madwifi: filter wireless events based on ifindex to allow more 1028 than one network interface to be used 1029 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt 1030 setting if the packet does not pass MIC verification (e.g., due to 1031 incorrect PSK); previously, message 1/4 was not tried again if an 1032 invalid message 2/4 was received 1033 * fixed reconfiguration of RADIUS client retransmission timer when 1034 adding a new message to the pending list; previously, timer was not 1035 updated at this point and if there was a pending message with long 1036 time for the next retry, the new message needed to wait that long for 1037 its first retry, too 1038 10392005-01-09 - v0.3.4 1040 * added support for configuring multiple allowed EAP types for Phase 2 1041 authentication (EAP-PEAP, EAP-TTLS) 1042 * fixed EAPOL-Start processing to trigger WPA reauthentication 1043 (previously, only EAPOL authentication was done) 1044 10452005-01-02 - v0.3.3 1046 * added support for EAP-PEAP in the integrated EAP authenticator 1047 * added support for EAP-GTC in the integrated EAP authenticator 1048 * added support for configuring list of EAP methods for Phase 1 so that 1049 the integrated EAP authenticator can, e.g., use the wildcard entry 1050 for EAP-TLS and EAP-PEAP 1051 * added support for EAP-TTLS in the integrated EAP authenticator 1052 * added support for EAP-SIM in the integrated EAP authenticator 1053 * added support for using hostapd as a RADIUS authentication server 1054 with the integrated EAP authenticator taking care of EAP 1055 authentication (new hostapd.conf options: radius_server_clients and 1056 radius_server_auth_port); this is not included in default build; use 1057 CONFIG_RADIUS_SERVER=y in .config to include 1058 10592004-12-19 - v0.3.2 1060 * removed 'daemonize' configuration file option since it has not really 1061 been used at all for more than year 1062 * driver_madwifi: fixed group key setup and added get_ssid method 1063 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator 1064 10652004-12-12 - v0.3.1 1066 * added support for integrated EAP-TLS authentication (new hostapd.conf 1067 variables: ca_cert, server_cert, private_key, private_key_passwd); 1068 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without 1069 external RADIUS server 1070 * added support for reading PKCS#12 (PFX) files (as a replacement for 1071 PEM/DER) to get certificate and private key (CONFIG_PKCS12) 1072 10732004-12-05 - v0.3.0 (beginning of 0.3.x development releases) 1074 * added support for Acct-{Input,Output}-Gigawords 1075 * added support for Event-Timestamp (in RADIUS Accounting-Requests) 1076 * added support for RADIUS Authentication Client MIB (RFC2618) 1077 * added support for RADIUS Accounting Client MIB (RFC2620) 1078 * made EAP re-authentication period configurable (eap_reauth_period) 1079 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication 1080 * fixed EAPOL state machine to stop if STA is removed during 1081 eapol_sm_step(); this fixes at least one segfault triggering bug with 1082 IEEE 802.11i pre-authentication 1083 * added support for multiple WPA pre-shared keys (e.g., one for each 1084 client MAC address or keys shared by a group of clients); 1085 new hostapd.conf field wpa_psk_file for setting path to a text file 1086 containing PSKs, see hostapd.wpa_psk for an example 1087 * added support for multiple driver interfaces to allow hostapd to be 1088 used with other drivers 1089 * added wired authenticator driver interface (driver=wired in 1090 hostapd.conf, see wired.conf for example configuration) 1091 * added madwifi driver interface (driver=madwifi in hostapd.conf, see 1092 madwifi.conf for example configuration; Note: include files from 1093 madwifi project is needed for building and a configuration file, 1094 .config, needs to be created in hostapd directory with 1095 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd 1096 build) 1097 * fixed an alignment issue that could cause SHA-1 to fail on some 1098 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit 1099 align variables) 1100 * fixed RADIUS reconnection after an error in sending interim 1101 accounting packets 1102 * added hostapd control interface for external programs and an example 1103 CLI, hostapd_cli (like wpa_cli for wpa_supplicant) 1104 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib', 1105 'hostapd_cli sta <addr>') 1106 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11) 1107 * added support for strict GTK rekeying (wpa_strict_rekey in 1108 hostapd.conf) 1109 * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178 1110 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to 1111 IEEE 802.11F-2003) 1112 * added Prism54 driver interface (driver=prism54 in hostapd.conf; 1113 note: .config needs to be created in hostapd directory with 1114 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd 1115 build) 1116 * dual-licensed hostapd (GPLv2 and BSD licenses) 1117 * fixed RADIUS accounting to generate a new session id for cases where 1118 a station reassociates without first being complete deauthenticated 1119 * fixed STA disassociation handler to mark next timeout state to 1120 deauthenticate the station, i.e., skip long wait for inactivity poll 1121 and extra disassociation, if the STA disassociates without 1122 deauthenticating 1123 * added integrated EAP authenticator that can be used instead of 1124 external RADIUS authentication server; currently, only EAP-MD5 is 1125 supported, so this cannot yet be used for key distribution; the EAP 1126 method interface is generic, though, so adding new EAP methods should 1127 be straightforward; new hostapd.conf variables: 'eap_authenticator' 1128 and 'eap_user_file'; this obsoletes "minimal authentication server" 1129 ('minimal_eap' in hostapd.conf) which is now removed 1130 * added support for FreeBSD and driver interface for the BSD net80211 1131 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in 1132 .config); please note that some of the required kernel mods have not 1133 yet been committed 1134 11352004-07-17 - v0.2.4 (beginning of 0.2.x stable releases) 1136 * fixed some accounting cases where Accounting-Start was sent when 1137 IEEE 802.1X port was being deauthorized 1138 11392004-06-20 - v0.2.3 1140 * modified RADIUS client to re-connect the socket in case of certain 1141 error codes that are generated when a network interface state is 1142 changes (e.g., when IP address changes or the interface is set UP) 1143 * fixed couple of cases where EAPOL state for a station was freed 1144 twice causing a segfault for hostapd 1145 * fixed couple of bugs in processing WPA deauthentication (freed data 1146 was used) 1147 11482004-05-31 - v0.2.2 1149 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM) 1150 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix 1151 cases where STAs dropped multicast frames as replay attacks 1152 * added support for copying RADIUS Attribute 'Class' from 1153 authentication messages into accounting messages 1154 * send canned EAP failure if RADIUS server sends Access-Reject without 1155 EAP message (previously, Supplicant was not notified in this case) 1156 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do 1157 not start EAPOL state machines if the STA selected to use WPA-PSK) 1158 11592004-05-06 - v0.2.1 1160 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality 1161 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA 1162 (i.e., IEEE 802.11i/D3.0) 1163 - supports WPA-only, RSN-only, and mixed WPA/RSN mode 1164 - both WPA-PSK and WPA-RADIUS/EAP are supported 1165 - PMKSA caching and pre-authentication 1166 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase, 1167 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey, 1168 rsn_preauth, rsn_preauth_interfaces 1169 * fixed interim accounting to remove any pending accounting messages 1170 to the STA before sending a new one 1171 11722004-02-15 - v0.2.0 1173 * added support for Acct-Interim-Interval: 1174 - draft-ietf-radius-acct-interim-01.txt 1175 - use Acct-Interim-Interval attribute from Access-Accept if local 1176 'radius_acct_interim_interval' is not set 1177 - allow different update intervals for each STA 1178 * fixed event loop to call signal handlers only after returning from 1179 the real signal handler 1180 * reset sta->timeout_next after successful association to make sure 1181 that the previously registered inactivity timer will not remove the 1182 STA immediately (e.g., if STA deauthenticates and re-associates 1183 before the timer is triggered). 1184 * added new hostapd.conf variable, nas_identifier, that can be used to 1185 add an optional RADIUS Attribute, NAS-Identifier, into authentication 1186 and accounting messages 1187 * added support for Accounting-On and Accounting-Off messages 1188 * fixed accounting session handling to send Accounting-Start only once 1189 per session and not to send Accounting-Stop if the session was not 1190 initialized properly 1191 * fixed Accounting-Stop statistics in cases where the message was 1192 previously sent after the kernel entry for the STA (and/or IEEE 1193 802.1X data) was removed 1194 1195 1196Note: 1197 1198Older changes up to and including v0.1.0 are included in the ChangeLog 1199of the Host AP driver. 1200
