this version is not 512 backwards compatible with old versions 513 * add SA Query Request processing in AP mode (IEEE 802.11w) 514 * fix IGTK PN in group rekeying (IEEE 802.11w) 515 * fix WPS PBC session overlap detection to use correct attribute 516 * hostapd_notif_Assoc() can now be called with all IEs to simplify 517 driver wrappers 518 * work around interoperability issue with some WPS External Registrar 519 implementations 520 * nl80211: fix WPS IE update 521 * hostapd_cli: add support for action script operations (run a script 522 on hostapd events) 523 * fix DH padding with internal crypto code (mainly, for WPS) 524 * fix WPS association with both WPS IE and WPA/RSN IE present with 525 driver wrappers that use hostapd MLME (e.g., nl80211) 526 527 2010-01-16 - v0.7.1 528 * cleaned up driver wrapper API (struct wpa_driver_ops); the new API 529 is not fully backwards compatible, so out-of-tree driver wrappers 530 will need modifications 531 * cleaned up various module interfaces 532 * merge hostapd and wpa_supplicant developers' documentation into a 533 single document 534 * fixed HT Capabilities IE with nl80211 drivers 535 * moved generic AP functionality code into src/ap 536 * WPS: handle Selected Registrar as union of info from all Registrars 537 * remove obsolte Prism54.org driver wrapper 538 * added internal debugging mechanism with backtrace support and memory 539 allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y) 540 * EAP-FAST server: piggyback Phase 2 start with the end of Phase 1 541 * WPS: add support for dynamically selecting whether to provision the 542 PSK as an ASCII passphrase or PSK 543 * added support for WDS (4-address frame) mode with per-station virtual 544 interfaces (wds_sta=1 in config file; only supported with 545 driver=nl80211 for now) 546 * fixed WPS Probe Request processing to handle missing required 547 attribute 548 * fixed PKCS#12 use with OpenSSL 1.0.0 549 * detect bridge interface automatically so that bridge parameter in 550 hostapd.conf becomes optional (though, it may now be used to 551 automatically add then WLAN interface into a bridge with 552 driver=nl80211) 553 554 2009-11-21 - v0.7.0 555 * increased hostapd_cli ping interval to 5 seconds and made this 556 configurable with a new command line options (-G<seconds>) 557 * driver_nl80211: use Linux socket filter to improve performance 558 * added support for external Registrars with WPS (UPnP transport) 559 * 802.11n: scan for overlapping BSSes before starting 20/40 MHz channel 560 * driver_nl80211: fixed STA accounting data collection (TX/RX bytes 561 reported correctly; TX/RX packets not yet available from kernel) 562 * added support for WPS USBA out-of-band mechanism with USB Flash 563 Drives (UFD) (CONFIG_WPS_UFD=y) 564 * fixed EAPOL/EAP reauthentication when using an external RADIUS 565 authentication server 566 * fixed TNC with EAP-TTLS 567 * fixed IEEE 802.11r key derivation function to match with the standard 568 (note: this breaks interoperability with previous version) [Bug 303] 569 * fixed SHA-256 based key derivation function to match with the 570 standard when using CCMP (for IEEE 802.11r and IEEE 802.11w) 571 (note: this breaks interoperability with previous version) [Bug 307] 572 * added number of code size optimizations to remove unnecessary 573 functionality from the program binary based on build configuration 574 (part of this automatic; part configurable with CONFIG_NO_* build 575 options) 576 * use shared driver wrapper files with wpa_supplicant 577 * driver_nl80211: multiple updates to provide support for new Linux 578 nl80211/mac80211 functionality 579 * updated management frame protection to use IEEE Std 802.11w-2009 580 * fixed number of small WPS issues and added workarounds to 581 interoperate with common deployed broken implementations 582 * added some IEEE 802.11n co-existence rules to disable 40 MHz channels 583 or modify primary/secondary channels if needed based on neighboring 584 networks 585 * added support for NFC out-of-band mechanism with WPS 586 * added preliminary support for IEEE 802.11r RIC processing 587 588 2009-01-06 - v0.6.7 589 * added support for Wi-Fi Protected Setup (WPS) 590 (hostapd can now be configured to act as an integrated WPS Registrar 591 and provision credentials for WPS Enrollees using PIN and PBC 592 methods; external wireless Registrar can configure the AP, but 593 external WLAN Manager Registrars are not supported); WPS support can 594 be enabled by adding CONFIG_WPS=y into .config and setting the 595 runtime configuration variables in hostapd.conf (see WPS section in 596 the example configuration file); new hostapd_cli commands wps_pin and 597 wps_pbc are used to configure WPS negotiation; see README-WPS for 598 more details 599 * added IEEE 802.11n HT capability configuration (ht_capab) 600 * added support for generating Country IE based on nl80211 regulatory 601 information (added if ieee80211d=1 in configuration) 602 * fixed WEP authentication (both Open System and Shared Key) with 603 mac80211 604 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf) 605 * added support for using driver_test over UDP socket 606 * changed EAP-GPSK to use the IANA assigned EAP method type 51 607 * updated management frame protection to use IEEE 802.11w/D7.0 608 * fixed retransmission of EAP requests if no response is received 609 610 2008-11-23 - v0.6.6 611 * added a new configuration option, wpa_ptk_rekey, that can be used to 612 enforce frequent PTK rekeying, e.g., to mitigate some attacks against 613 TKIP deficiencies 614 * updated OpenSSL code for EAP-FAST to use an updated version of the 615 session ticket overriding API that was included into the upstream 616 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is 617 needed with that version anymore) 618 * changed channel flags configuration to read the information from 619 the driver (e.g., via driver_nl80211 when using mac80211) instead of 620 using hostapd as the source of the regulatory information (i.e., 621 information from CRDA is now used with mac80211); this allows 5 GHz 622 channels to be used with hostapd (if allowed in the current 623 regulatory domain) 624 * fixed EAP-TLS message processing for the last TLS message if it is 625 large enough to require fragmentation (e.g., if a large Session 626 Ticket data is included) 627 * fixed listen interval configuration for nl80211 drivers 628 629 2008-11-01 - v0.6.5 630 * added support for SHA-256 as X.509 certificate digest when using the 631 internal X.509/TLSv1 implementation 632 * fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer 633 identity lengths) 634 * fixed internal TLSv1 implementation for abbreviated handshake (used 635 by EAP-FAST server) 636 * added support for setting VLAN ID for STAs based on local MAC ACL 637 (accept_mac_file) as an alternative for RADIUS server-based 638 configuration 639 * updated management frame protection to use IEEE 802.11w/D6.0 640 (adds a new association ping to protect against unauthenticated 641 authenticate or (re)associate request frames dropping association) 642 * added support for using SHA256-based stronger key derivation for WPA2 643 (IEEE 802.11w) 644 * added new "driver wrapper" for RADIUS-only configuration 645 (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config) 646 * fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2) 647 is enabled in configuration 648 * changed EAP-FAST configuration to use separate fields for A-ID and 649 A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed 650 16-octet len binary value for better interoperability with some peer 651 implementations; eap_fast_a_id is now configured as a hex string 652 * driver_nl80211: Updated to match the current Linux mac80211 AP mode 653 configuration (wireless-testing.git and Linux kernel releases 654 starting from 2.6.29) 655 656 2008-08-10 - v0.6.4 657 * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2 658 Identity Request if identity is already known 659 * added support for EAP Sequences in EAP-FAST Phase 2 660 * added support for EAP-TNC (Trusted Network Connect) 661 (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST 662 changes needed to run two methods in sequence (IF-T) and the IF-IMV 663 and IF-TNCCS interfaces from TNCS) 664 * added support for optional cryptobinding with PEAPv0 665 * added fragmentation support for EAP-TNC 666 * added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled) 667 data 668 * added support for opportunistic key caching (OKC) 669 670 2008-02-22 - v0.6.3 671 * fixed Reassociation Response callback processing when using internal 672 MLME (driver_{hostap,nl80211,test}.c) 673 * updated FT support to use the latest draft, IEEE 802.11r/D9.0 674 * copy optional Proxy-State attributes into RADIUS response when acting 675 as a RADIUS authentication server 676 * fixed EAPOL state machine to handle a case in which no response is 677 received from the RADIUS authentication server; previous version 678 could have triggered a crash in some cases after a timeout 679 * fixed EAP-SIM/AKA realm processing to allow decorated usernames to 680 be used 681 * added a workaround for EAP-SIM/AKA peers that include incorrect null 682 termination in the username 683 * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER 684 attribute in notification messages only when using fast 685 reauthentication 686 * fixed EAP-SIM Start response processing for fast reauthentication 687 case 688 * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST} 689 phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method 690 691 2008-01-01 - v0.6.2 692 * fixed EAP-SIM and EAP-AKA message parser to validate attribute 693 lengths properly to avoid potential crash caused by invalid messages 694 * added data structure for storing allocated buffers (struct wpabuf); 695 this does not affect hostapd usage, but many of the APIs changed 696 and various interfaces (e.g., EAP) is not compatible with old 697 versions 698 * added support for protecting EAP-AKA/Identity messages with 699 AT_CHECKCODE (optional feature in RFC 4187) 700 * added support for protected result indication with AT_RESULT_IND for 701 EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1) 702 * added support for configuring EAP-TTLS phase 2 non-EAP methods in 703 EAP server configuration; previously all four were enabled for every 704 phase 2 user, now all four are disabled by default and need to be 705 enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP, 706 TTLS-MSCHAPV2 707 * removed old debug printing mechanism and the related 'debug' 708 parameter in the configuration file; debug verbosity is now set with 709 -d (or -dd) command line arguments 710 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt); 711 only shared key/password authentication is supported in this version 712 713 2007-11-24 - v0.6.1 714 * added experimental, integrated TLSv1 server implementation with the 715 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by 716 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in 717 .config); this can be useful, e.g., if the target system does not 718 have a suitable TLS library and a minimal code size is required 719 * added support for EAP-FAST server method to the integrated EAP 720 server 721 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 722 draft (draft-ietf-emu-eap-gpsk-07.txt) 723 * added a new configuration parameter, rsn_pairwise, to allow different 724 pairwise cipher suites to be enabled for WPA and RSN/WPA2 725 (note: if wpa_pairwise differs from rsn_pairwise, the driver will 726 either need to support this or will have to use the WPA/RSN IEs from 727 hostapd; currently, the included madwifi and bsd driver interfaces do 728 not have support for this) 729 * updated FT support to use the latest draft, IEEE 802.11r/D8.0 730 731 2007-05-28 - v0.6.0 732 * added experimental IEEE 802.11r/D6.0 support 733 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48 734 * updated EAP-PSK to use the IANA-allocated EAP type 47 735 * fixed EAP-PSK bit ordering of the Flags field 736 * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs 737 by reading wpa_psk_file [Bug 181] 738 * fixed EAP-TTLS AVP parser processing for too short AVP lengths 739 * fixed IPv6 connection to RADIUS accounting server 740 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 741 draft (draft-ietf-emu-eap-gpsk-04.txt) 742 * hlr_auc_gw: read GSM triplet file into memory and rotate through the 743 entries instead of only using the same three triplets every time 744 (this does not work properly with tests using multiple clients, but 745 provides bit better triplet data for testing a single client; anyway, 746 if a better quality triplets are needed, GSM-Milenage should be used 747 instead of hardcoded triplet file) 748 * fixed EAP-MSCHAPv2 server to use a space between S and M parameters 749 in Success Request [Bug 203] 750 * added support for sending EAP-AKA Notifications in error cases 751 * updated to use IEEE 802.11w/D2.0 for management frame protection 752 (still experimental) 753 * RADIUS server: added support for processing duplicate messages 754 (retransmissions from RADIUS client) by replying with the previous 755 reply 756 757 2006-11-24 - v0.5.6 758 * added support for configuring and controlling multiple BSSes per 759 radio interface (bss=<ifname> in hostapd.conf); this is only 760 available with Devicescape and test driver interfaces 761 * fixed PMKSA cache update in the end of successful RSN 762 pre-authentication 763 * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID 764 for each STA based on RADIUS Access-Accept attributes); this requires 765 VLAN support from the kernel driver/802.11 stack and this is 766 currently only available with Devicescape and test driver interfaces 767 * driver_madwifi: fixed configuration of unencrypted modes (plaintext 768 and IEEE 802.1X without WEP) 769 * removed STAKey handshake since PeerKey handshake has replaced it in 770 IEEE 802.11ma and there are no known deployments of STAKey 771 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 772 draft (draft-ietf-emu-eap-gpsk-01.txt) 773 * added preliminary implementation of IEEE 802.11w/D1.0 (management 774 frame protection) 775 (Note: this requires driver support to work properly.) 776 (Note2: IEEE 802.11w is an unapproved draft and subject to change.) 777 * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM) 778 * hlr_auc_gw: added support for reading per-IMSI Milenage keys and 779 parameters from a text file to make it possible to implement proper 780 GSM/UMTS authentication server for multiple SIM/USIM cards using 781 EAP-SIM/EAP-AKA 782 * fixed session timeout processing with drivers that do not use 783 ieee802_11.c (e.g., madwifi) 784 785 2006-08-27 - v0.5.5 786 * added 'hostapd_cli new_sta <addr>' command for adding a new STA into 787 hostapd (e.g., to initialize wired network authentication based on an 788 external signal) 789 * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when 790 using WPA2 even if PMKSA caching is not used 791 * added -P<pid file> argument for hostapd to write the current process 792 id into a file 793 * added support for RADIUS Authentication Server MIB (RFC 2619) 794 795 2006-06-20 - v0.5.4 796 * fixed nt_password_hash build [Bug 144] 797 * added PeerKey handshake implementation for IEEE 802.11e 798 direct link setup (DLS) to replace STAKey handshake 799 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK, 800 draft-clancy-emu-eap-shared-secret-00.txt) 801 * fixed a segmentation fault when RSN pre-authentication was completed 802 successfully [Bug 152] 803 804 2006-04-27 - v0.5.3 805 * do not build nt_password_hash and hlr_auc_gw by default to avoid 806 requiring a TLS library for a successful build; these programs can be 807 build with 'make nt_password_hash' and 'make hlr_auc_gw' 808 * added a new configuration option, eapol_version, that can be used to 809 set EAPOL version to 1 (default is 2) to work around broken client 810 implementations that drop EAPOL frames which use version number 2 811 [Bug 89] 812 * added support for EAP-SAKE (no EAP method number allocated yet, so 813 this is using the same experimental type 255 as EAP-PSK) 814 * fixed EAP-MSCHAPv2 message length validation 815 816 2006-03-19 - v0.5.2 817 * fixed stdarg use in hostapd_logger(): if both stdout and syslog 818 logging was enabled, hostapd could trigger a segmentation fault in 819 vsyslog on some CPU -- C library combinations 820 * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external 821 program to make it easier to use for implementing real SS7 gateway; 822 eap_sim_db is not anymore used as a file name for GSM authentication 823 triplets; instead, it is path to UNIX domain socket that will be used 824 to communicate with the external gateway program (e.g., hlr_auc_gw) 825 * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses 826 local information (GSM authentication triplets from a text file and 827 hardcoded AKA authentication data); this can be used to test EAP-SIM 828 and EAP-AKA 829 * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw 830 to make it possible to test EAP-AKA with real USIM cards (this is 831 disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw 832 to enable this) 833 * driver_madwifi: added support for getting station RSN IE from 834 madwifi-ng svn r1453 and newer; this fixes RSN that was apparently 835 broken with earlier change (r1357) in the driver 836 * changed EAP method registration to use a dynamic list of methods 837 instead of a static list generated at build time 838 * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE) 839 [Bug 125] 840 * added ap_max_inactivity configuration parameter 841 842 2006-01-29 - v0.5.1 843 * driver_test: added better support for multiple APs and STAs by using 844 a directory with sockets that include MAC address for each device in 845 the name (test_socket=DIR:/tmp/test) 846 * added support for EAP expanded type (vendor specific EAP methods) 847 848 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases) 849 * added experimental STAKey handshake implementation for IEEE 802.11e 850 direct link setup (DLS); note: this is disabled by default in both 851 build and runtime configuration (can be enabled with CONFIG_STAKEY=y 852 and stakey=1) 853 * added support for EAP methods to use callbacks to external programs 854 by buffering a pending request and processing it after the EAP method 855 is ready to continue 856 * improved EAP-SIM database interface to allow external request to GSM 857 HLR/AuC without blocking hostapd process 858 * added support for using EAP-SIM pseudonyms and fast re-authentication 859 * added support for EAP-AKA in the integrated EAP authenticator 860 * added support for matching EAP identity prefixes (e.g., "1"*) in EAP 861 user database to allow EAP-SIM/AKA selection without extra roundtrip 862 for EAP-Nak negotiation 863 * added support for storing EAP user password as NtPasswordHash instead 864 of plaintext password when using MSCHAP or MSCHAPv2 for 865 authentication (hash:<16-octet hex value>); added nt_password_hash 866 tool for hashing password to generate NtPasswordHash 867 868 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases) 869 * driver_wired: fixed EAPOL sending to optionally use PAE group address 870 as the destination instead of supplicant MAC address; this is 871 disabled by default, but should be enabled with use_pae_group_addr=1 872 in configuration file if the wired interface is used by only one 873 device at the time (common switch configuration) 874 * driver_madwifi: configure driver to use TKIP countermeasures in order 875 to get correct behavior (IEEE 802.11 association failing; previously, 876 association succeeded, but hostpad forced disassociation immediately) 877 * driver_madwifi: added support for madwifi-ng 878 879 2005-10-27 - v0.4.6 880 * added support for replacing user identity from EAP with RADIUS 881 User-Name attribute from Access-Accept message, if that is included, 882 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get 883 tunneled identity into accounting messages when the RADIUS server 884 does not support better way of doing this with Class attribute) 885 * driver_madwifi: fixed EAPOL packet receive for configuration where 886 ath# is part of a bridge interface 887 * added a configuration file and log analyzer script for logwatch 888 * fixed EAPOL state machine step function to process all state 889 transitions before processing new events; this resolves a race 890 condition in which EAPOL-Start message could trigger hostapd to send 891 two EAP-Response/Identity frames to the authentication server 892 893 2005-09-25 - v0.4.5 894 * added client CA list to the TLS certificate request in order to make 895 it easier for the client to select which certificate to use 896 * added experimental support for EAP-PSK 897 * added support for WE-19 (hostap, madwifi) 898 899 2005-08-21 - v0.4.4 900 * fixed build without CONFIG_RSN_PREAUTH 901 * fixed FreeBSD build 902 903 2005-06-26 - v0.4.3 904 * fixed PMKSA caching to copy User-Name and Class attributes so that 905 RADIUS accounting gets correct information 906 * start RADIUS accounting only after successful completion of WPA 907 4-Way Handshake if WPA-PSK is used 908 * fixed PMKSA caching for the case where STA (re)associates without 909 first disassociating 910 911 2005-06-12 - v0.4.2 912 * EAP-PAX is now registered as EAP type 46 913 * fixed EAP-PAX MAC calculation 914 * fixed EAP-PAX CK and ICK key derivation 915 * renamed eap_authenticator configuration variable to eap_server to 916 better match with RFC 3748 (EAP) terminology 917 * driver_test: added support for testing hostapd with wpa_supplicant 918 by using test driver interface without any kernel drivers or network 919 cards 920 921 2005-05-22 - v0.4.1 922 * fixed RADIUS server initialization when only auth or acct server 923 is configured and the other one is left empty 924 * driver_madwifi: added support for RADIUS accounting 925 * driver_madwifi: added preliminary support for compiling against 'BSD' 926 branch of madwifi CVS tree 927 * driver_madwifi: fixed pairwise key removal to allow WPA reauth 928 without disassociation 929 * added support for reading additional certificates from PKCS#12 files 930 and adding them to the certificate chain 931 * fixed RADIUS Class attribute processing to only use Access-Accept 932 packets to update Class; previously, other RADIUS authentication 933 packets could have cleared Class attribute 934 * added support for more than one Class attribute in RADIUS packets 935 * added support for verifying certificate revocation list (CRL) when 936 using integrated EAP authenticator for EAP-TLS; new hostapd.conf 937 options 'check_crl'; CRL must be included in the ca_cert file for now 938 939 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases) 940 * added support for including network information into 941 EAP-Request/Identity message (ASCII-0 (nul) in eap_message) 942 (e.g., to implement draft-adrange-eap-network-discovery-07.txt) 943 * fixed a bug which caused some RSN pre-authentication cases to use 944 freed memory and potentially crash hostapd 945 * fixed private key loading for cases where passphrase is not set 946 * added support for sending TLS alerts and aborting authentication 947 when receiving a TLS alert 948 * fixed WPA2 to add PMKSA cache entry when using integrated EAP 949 authenticator 950 * fixed PMKSA caching (EAP authentication was not skipped correctly 951 with the new state machine changes from IEEE 802.1X draft) 952 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr, 953 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs 954 to be added to .config to include IPv6 support); for RADIUS server, 955 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses 956 in RADIUS clients file can then use IPv6 format 957 * added experimental support for EAP-PAX 958 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with 959 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch]) 960 961 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases) 962 963 2005-01-23 - v0.3.5 964 * added support for configuring a forced PEAP version based on the 965 Phase 1 identity 966 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV 967 to terminate authentication 968 * fixed EAP identifier duplicate processing with the new IEEE 802.1X 969 draft 970 * clear accounting data in the driver when starting a new accounting 971 session 972 * driver_madwifi: filter wireless events based on ifindex to allow more 973 than one network interface to be used 974 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt 975 setting if the packet does not pass MIC verification (e.g., due to 976 incorrect PSK); previously, message 1/4 was not tried again if an 977 invalid message 2/4 was received 978 * fixed reconfiguration of RADIUS client retransmission timer when 979 adding a new message to the pending list; previously, timer was not 980 updated at this point and if there was a pending message with long 981 time for the next retry, the new message needed to wait that long for 982 its first retry, too 983 984 2005-01-09 - v0.3.4 985 * added support for configuring multiple allowed EAP types for Phase 2 986 authentication (EAP-PEAP, EAP-TTLS) 987 * fixed EAPOL-Start processing to trigger WPA reauthentication 988 (previously, only EAPOL authentication was done) 989 990 2005-01-02 - v0.3.3 991 * added support for EAP-PEAP in the integrated EAP authenticator 992 * added support for EAP-GTC in the integrated EAP authenticator 993 * added support for configuring list of EAP methods for Phase 1 so that 994 the integrated EAP authenticator can, e.g., use the wildcard entry 995 for EAP-TLS and EAP-PEAP 996 * added support for EAP-TTLS in the integrated EAP authenticator 997 * added support for EAP-SIM in the integrated EAP authenticator 998 * added support for using hostapd as a RADIUS authentication server 999 with the integrated EAP authenticator taking care of EAP 1000 authentication (new hostapd.conf options: radius_server_clients and 1001 radius_server_auth_port); this is not included in default build; use 1002 CONFIG_RADIUS_SERVER=y in .config to include 1003 1004 2004-12-19 - v0.3.2 1005 * removed 'daemonize' configuration file option since it has not really 1006 been used at all for more than year 1007 * driver_madwifi: fixed group key setup and added get_ssid method 1008 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator 1009 1010 2004-12-12 - v0.3.1 1011 * added support for integrated EAP-TLS authentication (new hostapd.conf 1012 variables: ca_cert, server_cert, private_key, private_key_passwd); 1013 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without 1014 external RADIUS server 1015 * added support for reading PKCS#12 (PFX) files (as a replacement for 1016 PEM/DER) to get certificate and private key (CONFIG_PKCS12) 1017 1018 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases) 1019 * added support for Acct-{Input,Output}-Gigawords 1020 * added support for Event-Timestamp (in RADIUS Accounting-Requests) 1021 * added support for RADIUS Authentication Client MIB (RFC2618) 1022 * added support for RADIUS Accounting Client MIB (RFC2620) 1023 * made EAP re-authentication period configurable (eap_reauth_period) 1024 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication 1025 * fixed EAPOL state machine to stop if STA is removed during 1026 eapol_sm_step(); this fixes at least one segfault triggering bug with 1027 IEEE 802.11i pre-authentication 1028 * added support for multiple WPA pre-shared keys (e.g., one for each 1029 client MAC address or keys shared by a group of clients); 1030 new hostapd.conf field wpa_psk_file for setting path to a text file 1031 containing PSKs, see hostapd.wpa_psk for an example 1032 * added support for multiple driver interfaces to allow hostapd to be 1033 used with other drivers 1034 * added wired authenticator driver interface (driver=wired in 1035 hostapd.conf, see wired.conf for example configuration) 1036 * added madwifi driver interface (driver=madwifi in hostapd.conf, see 1037 madwifi.conf for example configuration; Note: include files from 1038 madwifi project is needed for building and a configuration file, 1039 .config, needs to be created in hostapd directory with 1040 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd 1041 build) 1042 * fixed an alignment issue that could cause SHA-1 to fail on some 1043 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit 1044 align variables) 1045 * fixed RADIUS reconnection after an error in sending interim 1046 accounting packets 1047 * added hostapd control interface for external programs and an example 1048 CLI, hostapd_cli (like wpa_cli for wpa_supplicant) 1049 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib', 1050 'hostapd_cli sta <addr>') 1051 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11) 1052 * added support for strict GTK rekeying (wpa_strict_rekey in 1053 hostapd.conf) 1054 * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178 1055 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to 1056 IEEE 802.11F-2003) 1057 * added Prism54 driver interface (driver=prism54 in hostapd.conf; 1058 note: .config needs to be created in hostapd directory with 1059 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd 1060 build) 1061 * dual-licensed hostapd (GPLv2 and BSD licenses) 1062 * fixed RADIUS accounting to generate a new session id for cases where 1063 a station reassociates without first being complete deauthenticated 1064 * fixed STA disassociation handler to mark next timeout state to 1065 deauthenticate the station, i.e., skip long wait for inactivity poll 1066 and extra disassociation, if the STA disassociates without 1067 deauthenticating 1068 * added integrated EAP authenticator that can be used instead of 1069 external RADIUS authentication server; currently, only EAP-MD5 is 1070 supported, so this cannot yet be used for key distribution; the EAP 1071 method interface is generic, though, so adding new EAP methods should 1072 be straightforward; new hostapd.conf variables: 'eap_authenticator' 1073 and 'eap_user_file'; this obsoletes "minimal authentication server" 1074 ('minimal_eap' in hostapd.conf) which is now removed 1075 * added support for FreeBSD and driver interface for the BSD net80211 1076 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in 1077 .config); please note that some of the required kernel mods have not 1078 yet been committed 1079 1080 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases) 1081 * fixed some accounting cases where Accounting-Start was sent when 1082 IEEE 802.1X port was being deauthorized 1083 1084 2004-06-20 - v0.2.3 1085 * modified RADIUS client to re-connect the socket in case of certain 1086 error codes that are generated when a network interface state is 1087 changes (e.g., when IP address changes or the interface is set UP) 1088 * fixed couple of cases where EAPOL state for a station was freed 1089 twice causing a segfault for hostapd 1090 * fixed couple of bugs in processing WPA deauthentication (freed data 1091 was used) 1092 1093 2004-05-31 - v0.2.2 1094 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM) 1095 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix 1096 cases where STAs dropped multicast frames as replay attacks 1097 * added support for copying RADIUS Attribute 'Class' from 1098 authentication messages into accounting messages 1099 * send canned EAP failure if RADIUS server sends Access-Reject without 1100 EAP message (previously, Supplicant was not notified in this case) 1101 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do 1102 not start EAPOL state machines if the STA selected to use WPA-PSK) 1103 1104 2004-05-06 - v0.2.1 1105 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality 1106 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA 1107 (i.e., IEEE 802.11i/D3.0) 1108 - supports WPA-only, RSN-only, and mixed WPA/RSN mode 1109 - both WPA-PSK and WPA-RADIUS/EAP are supported 1110 - PMKSA caching and pre-authentication 1111 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase, 1112 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey, 1113 rsn_preauth, rsn_preauth_interfaces 1114 * fixed interim accounting to remove any pending accounting messages 1115 to the STA before sending a new one 1116 1117 2004-02-15 - v0.2.0 1118 * added support for Acct-Interim-Interval: 1119 - draft-ietf-radius-acct-interim-01.txt 1120 - use Acct-Interim-Interval attribute from Access-Accept if local 1121 'radius_acct_interim_interval' is not set 1122 - allow different update intervals for each STA 1123 * fixed event loop to call signal handlers only after returning from 1124 the real signal handler 1125 * reset sta->timeout_next after successful association to make sure 1126 that the previously registered inactivity timer will not remove the 1127 STA immediately (e.g., if STA deauthenticates and re-associates 1128 before the timer is triggered). 1129 * added new hostapd.conf variable, nas_identifier, that can be used to 1130 add an optional RADIUS Attribute, NAS-Identifier, into authentication 1131 and accounting messages 1132 * added support for Accounting-On and Accounting-Off messages 1133 * fixed accounting session handling to send Accounting-Start only once 1134 per session and not to send Accounting-Stop if the session was not 1135 initialized properly 1136 * fixed Accounting-Stop statistics in cases where the message was 1137 previously sent after the kernel entry for the STA (and/or IEEE 1138 802.1X data) was removed 1139 1140 1141 Note: 1142 1143 Older changes up to and including v0.1.0 are included in the ChangeLog 1144 of the Host AP driver. 1145
