It works in the same way as new AP settings received 356 from an ER. 357 - Many WPS/WPS ER commands - see WPS/WPS ER sections for details. 358 - Add command get version, that returns hostapd version string. 359 * WNM: Add BSS Transition Management Request for ESS Disassoc Imminent. 360 Use hostapd_cli ess_disassoc (STA addr) (URL) to send the 361 notification to the STA. 362 * Allow AP mode to disconnect STAs based on low ACK condition (when 363 the data connection is not working properly, e.g., due to the STA 364 going outside the range of the AP). Disabled by default, enable by 365 config option disassoc_low_ack. 366 * Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad 367 config file. 368 * WPS: 369 - Send AP Settings as a wrapped Credential attribute to ctrl_iface 370 in WPS-NEW-AP-SETTINGS. 371 - Dispatch more WPS events through hostapd ctrl_iface. 372 - Add mechanism for indicating non-standard WPS errors. 373 - Change concurrent radio AP to use only one WPS UPnP instance. 374 - Add wps_check_pin command for processing PIN from user input. 375 UIs can use this command to process a PIN entered by a user and to 376 validate the checksum digit (if present). 377 - Add hostap_cli get_config command to display current AP config. 378 - Add new hostapd_cli command, wps_ap_pin, to manage AP PIN at 379 runtime and support dynamic AP PIN management. 380 - Disable AP PIN after 10 consecutive failures. Slow down attacks 381 on failures up to 10. 382 - Allow AP to start in Enrollee mode without AP PIN for probing, 383 to be compatible with Windows 7. 384 - Add Config Error into WPS-FAIL events to provide more info 385 to the user on how to resolve the issue. 386 - When controlling multiple interfaces: 387 - apply WPS commands to all interfaces configured to use WPS 388 - apply WPS config changes to all interfaces that use WPS 389 - when an attack is detected on any interface, disable AP PIN on 390 all interfaces 391 * WPS ER: 392 - Show SetSelectedRegistrar events as ctrl_iface events. 393 - Add special AP Setup Locked mode to allow read only ER. 394 ap_setup_locked=2 can now be used to enable a special mode where 395 WPS ER can learn the current AP settings, but cannot change them. 396 * WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2) 397 - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool 398 for testing protocol extensibility. 399 - Add build option CONFIG_WPS_STRICT to allow disabling of WPS 400 workarounds. 401 - Add support for AuthorizedMACs attribute. 402 * TDLS: 403 - Allow TDLS use or TDLS channel switching in the BSS to be 404 prohibited in the BSS, using config params tdls_prohibit and 405 tdls_prohibit_chan_switch. 406 * EAP server: Add support for configuring fragment size (see 407 fragment_size in hostapd.conf). 408 * wlantest: Add a tool wlantest for IEEE802.11 protocol testing. 409 wlantest can be used to capture frames from a monitor interface 410 for realtime capturing or from pcap files for offline analysis. 411 * Interworking: Support added for 802.11u. Enable in .config with 412 CONFIG_INTERWORKING. See hostapd.conf for config parameters for 413 interworking. 414 * Android: Add build and runtime support for Android hostapd. 415 * Add a new debug message level for excessive information. Use 416 -ddd to enable. 417 * TLS: Add support for tls_disable_time_checks=1 in client mode. 418 * Internal TLS: 419 - Add support for TLS v1.1 (RFC 4346). Enable with build parameter 420 CONFIG_TLSV11. 421 - Add domainComponent parser for X.509 names 422 * Reorder some IEs to get closer to IEEE 802.11 standard. Move 423 WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames. 424 Move HT IEs to be later in (Re)Assoc Resp. 425 * Many bugfixes. 426 427 2010-04-18 - v0.7.2 428 * fix WPS internal Registrar use when an external Registrar is also 429 active 430 * bsd: Cleaned up driver wrapper and added various low-level 431 configuration options 432 * TNC: fixed issues with fragmentation 433 * EAP-TNC: add Flags field into fragment acknowledgement (needed to 434 interoperate with other implementations;

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