It works in the same way as new AP settings received 320 from an ER. 321 - Many WPS/WPS ER commands - see WPS/WPS ER sections for details. 322 - Add command get version, that returns hostapd version string. 323 * WNM: Add BSS Transition Management Request for ESS Disassoc Imminent. 324 Use hostapd_cli ess_disassoc (STA addr) (URL) to send the 325 notification to the STA. 326 * Allow AP mode to disconnect STAs based on low ACK condition (when 327 the data connection is not working properly, e.g., due to the STA 328 going outside the range of the AP). Disabled by default, enable by 329 config option disassoc_low_ack. 330 * Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad 331 config file. 332 * WPS: 333 - Send AP Settings as a wrapped Credential attribute to ctrl_iface 334 in WPS-NEW-AP-SETTINGS. 335 - Dispatch more WPS events through hostapd ctrl_iface. 336 - Add mechanism for indicating non-standard WPS errors. 337 - Change concurrent radio AP to use only one WPS UPnP instance. 338 - Add wps_check_pin command for processing PIN from user input. 339 UIs can use this command to process a PIN entered by a user and to 340 validate the checksum digit (if present). 341 - Add hostap_cli get_config command to display current AP config. 342 - Add new hostapd_cli command, wps_ap_pin, to manage AP PIN at 343 runtime and support dynamic AP PIN management. 344 - Disable AP PIN after 10 consecutive failures. Slow down attacks 345 on failures up to 10. 346 - Allow AP to start in Enrollee mode without AP PIN for probing, 347 to be compatible with Windows 7. 348 - Add Config Error into WPS-FAIL events to provide more info 349 to the user on how to resolve the issue. 350 - When controlling multiple interfaces: 351 - apply WPS commands to all interfaces configured to use WPS 352 - apply WPS config changes to all interfaces that use WPS 353 - when an attack is detected on any interface, disable AP PIN on 354 all interfaces 355 * WPS ER: 356 - Show SetSelectedRegistrar events as ctrl_iface events. 357 - Add special AP Setup Locked mode to allow read only ER. 358 ap_setup_locked=2 can now be used to enable a special mode where 359 WPS ER can learn the current AP settings, but cannot change them. 360 * WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2) 361 - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool 362 for testing protocol extensibility. 363 - Add build option CONFIG_WPS_STRICT to allow disabling of WPS 364 workarounds. 365 - Add support for AuthorizedMACs attribute. 366 * TDLS: 367 - Allow TDLS use or TDLS channel switching in the BSS to be 368 prohibited in the BSS, using config params tdls_prohibit and 369 tdls_prohibit_chan_switch. 370 * EAP server: Add support for configuring fragment size (see 371 fragment_size in hostapd.conf). 372 * wlantest: Add a tool wlantest for IEEE802.11 protocol testing. 373 wlantest can be used to capture frames from a monitor interface 374 for realtime capturing or from pcap files for offline analysis. 375 * Interworking: Support added for 802.11u. Enable in .config with 376 CONFIG_INTERWORKING. See hostapd.conf for config parameters for 377 interworking. 378 * Android: Add build and runtime support for Android hostapd. 379 * Add a new debug message level for excessive information. Use 380 -ddd to enable. 381 * TLS: Add support for tls_disable_time_checks=1 in client mode. 382 * Internal TLS: 383 - Add support for TLS v1.1 (RFC 4346). Enable with build parameter 384 CONFIG_TLSV11. 385 - Add domainComponent parser for X.509 names 386 * Reorder some IEs to get closer to IEEE 802.11 standard. Move 387 WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames. 388 Move HT IEs to be later in (Re)Assoc Resp. 389 * Many bugfixes. 390 391 2010-04-18 - v0.7.2 392 * fix WPS internal Registrar use when an external Registrar is also 393 active 394 * bsd: Cleaned up driver wrapper and added various low-level 395 configuration options 396 * TNC: fixed issues with fragmentation 397 * EAP-TNC: add Flags field into fragment acknowledgement (needed to 398 interoperate with other implementations;

part configurable with CONFIG_NO_* build 466 options) 467 * use shared driver wrapper files with wpa_supplicant 468 * driver_nl80211: multiple updates to provide support for new Linux 469 nl80211/mac80211 functionality 470 * updated management frame protection to use IEEE Std 802.11w-2009 471 * fixed number of small WPS issues and added workarounds to 472 interoperate with common deployed broken implementations 473 * added some IEEE 802.11n co-existence rules to disable 40 MHz channels 474 or modify primary/secondary channels if needed based on neighboring 475 networks 476 * added support for NFC out-of-band mechanism with WPS 477 * added preliminary support for IEEE 802.11r RIC processing 478 479 2009-01-06 - v0.6.7 480 * added support for Wi-Fi Protected Setup (WPS) 481 (hostapd can now be configured to act as an integrated WPS Registrar 482 and provision credentials for WPS Enrollees using PIN and PBC 483 methods; external wireless Registrar can configure the AP, but 484 external WLAN Manager Registrars are not supported); WPS support can 485 be enabled by adding CONFIG_WPS=y into .config and setting the 486 runtime configuration variables in hostapd.conf (see WPS section in 487 the example configuration file); new hostapd_cli commands wps_pin and 488 wps_pbc are used to configure WPS negotiation; see README-WPS for 489 more details 490 * added IEEE 802.11n HT capability configuration (ht_capab) 491 * added support for generating Country IE based on nl80211 regulatory 492 information (added if ieee80211d=1 in configuration) 493 * fixed WEP authentication (both Open System and Shared Key) with 494 mac80211 495 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf) 496 * added support for using driver_test over UDP socket 497 * changed EAP-GPSK to use the IANA assigned EAP method type 51 498 * updated management frame protection to use IEEE 802.11w/D7.0 499 * fixed retransmission of EAP requests if no response is received 500 501 2008-11-23 - v0.6.6 502 * added a new configuration option, wpa_ptk_rekey, that can be used to 503 enforce frequent PTK rekeying, e.g., to mitigate some attacks against 504 TKIP deficiencies 505 * updated OpenSSL code for EAP-FAST to use an updated version of the 506 session ticket overriding API that was included into the upstream 507 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is 508 needed with that version anymore) 509 * changed channel flags configuration to read the information from 510 the driver (e.g., via driver_nl80211 when using mac80211) instead of 511 using hostapd as the source of the regulatory information (i.e., 512 information from CRDA is now used with mac80211); this allows 5 GHz 513 channels to be used with hostapd (if allowed in the current 514 regulatory domain) 515 * fixed EAP-TLS message processing for the last TLS message if it is 516 large enough to require fragmentation (e.g., if a large Session 517 Ticket data is included) 518 * fixed listen interval configuration for nl80211 drivers 519 520 2008-11-01 - v0.6.5 521 * added support for SHA-256 as X.509 certificate digest when using the 522 internal X.509/TLSv1 implementation 523 * fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer 524 identity lengths) 525 * fixed internal TLSv1 implementation for abbreviated handshake (used 526 by EAP-FAST server) 527 * added support for setting VLAN ID for STAs based on local MAC ACL 528 (accept_mac_file) as an alternative for RADIUS server-based 529 configuration 530 * updated management frame protection to use IEEE 802.11w/D6.0 531 (adds a new association ping to protect against unauthenticated 532 authenticate or (re)associate request frames dropping association) 533 * added support for using SHA256-based stronger key derivation for WPA2 534 (IEEE 802.11w) 535 * added new "driver wrapper" for RADIUS-only configuration 536 (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config) 537 * fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2) 538 is enabled in configuration 539 * changed EAP-FAST configuration to use separate fields for A-ID and 540 A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed 541 16-octet len binary value for better interoperability with some peer 542 implementations; eap_fast_a_id is now configured as a hex string 543 * driver_nl80211: Updated to match the current Linux mac80211 AP mode 544 configuration (wireless-testing.git and Linux kernel releases 545 starting from 2.6.29) 546 547 2008-08-10 - v0.6.4 548 * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2 549 Identity Request if identity is already known 550 * added support for EAP Sequences in EAP-FAST Phase 2 551 * added support for EAP-TNC (Trusted Network Connect) 552 (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST 553 changes needed to run two methods in sequence (IF-T) and the IF-IMV 554 and IF-TNCCS interfaces from TNCS) 555 * added support for optional cryptobinding with PEAPv0 556 * added fragmentation support for EAP-TNC 557 * added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled) 558 data 559 * added support for opportunistic key caching (OKC) 560 561 2008-02-22 - v0.6.3 562 * fixed Reassociation Response callback processing when using internal 563 MLME (driver_{hostap,nl80211,test}.c) 564 * updated FT support to use the latest draft, IEEE 802.11r/D9.0 565 * copy optional Proxy-State attributes into RADIUS response when acting 566 as a RADIUS authentication server 567 * fixed EAPOL state machine to handle a case in which no response is 568 received from the RADIUS authentication server; previous version 569 could have triggered a crash in some cases after a timeout 570 * fixed EAP-SIM/AKA realm processing to allow decorated usernames to 571 be used 572 * added a workaround for EAP-SIM/AKA peers that include incorrect null 573 termination in the username 574 * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER 575 attribute in notification messages only when using fast 576 reauthentication 577 * fixed EAP-SIM Start response processing for fast reauthentication 578 case 579 * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST} 580 phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method 581 582 2008-01-01 - v0.6.2 583 * fixed EAP-SIM and EAP-AKA message parser to validate attribute 584 lengths properly to avoid potential crash caused by invalid messages 585 * added data structure for storing allocated buffers (struct wpabuf); 586 this does not affect hostapd usage, but many of the APIs changed 587 and various interfaces (e.g., EAP) is not compatible with old 588 versions 589 * added support for protecting EAP-AKA/Identity messages with 590 AT_CHECKCODE (optional feature in RFC 4187) 591 * added support for protected result indication with AT_RESULT_IND for 592 EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1) 593 * added support for configuring EAP-TTLS phase 2 non-EAP methods in 594 EAP server configuration; previously all four were enabled for every 595 phase 2 user, now all four are disabled by default and need to be 596 enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP, 597 TTLS-MSCHAPV2 598 * removed old debug printing mechanism and the related 'debug' 599 parameter in the configuration file; debug verbosity is now set with 600 -d (or -dd) command line arguments 601 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt); 602 only shared key/password authentication is supported in this version 603 604 2007-11-24 - v0.6.1 605 * added experimental, integrated TLSv1 server implementation with the 606 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by 607 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in 608 .config); this can be useful, e.g., if the target system does not 609 have a suitable TLS library and a minimal code size is required 610 * added support for EAP-FAST server method to the integrated EAP 611 server 612 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 613 draft (draft-ietf-emu-eap-gpsk-07.txt) 614 * added a new configuration parameter, rsn_pairwise, to allow different 615 pairwise cipher suites to be enabled for WPA and RSN/WPA2 616 (note: if wpa_pairwise differs from rsn_pairwise, the driver will 617 either need to support this or will have to use the WPA/RSN IEs from 618 hostapd; currently, the included madwifi and bsd driver interfaces do 619 not have support for this) 620 * updated FT support to use the latest draft, IEEE 802.11r/D8.0 621 622 2007-05-28 - v0.6.0 623 * added experimental IEEE 802.11r/D6.0 support 624 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48 625 * updated EAP-PSK to use the IANA-allocated EAP type 47 626 * fixed EAP-PSK bit ordering of the Flags field 627 * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs 628 by reading wpa_psk_file [Bug 181] 629 * fixed EAP-TTLS AVP parser processing for too short AVP lengths 630 * fixed IPv6 connection to RADIUS accounting server 631 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 632 draft (draft-ietf-emu-eap-gpsk-04.txt) 633 * hlr_auc_gw: read GSM triplet file into memory and rotate through the 634 entries instead of only using the same three triplets every time 635 (this does not work properly with tests using multiple clients, but 636 provides bit better triplet data for testing a single client; anyway, 637 if a better quality triplets are needed, GSM-Milenage should be used 638 instead of hardcoded triplet file) 639 * fixed EAP-MSCHAPv2 server to use a space between S and M parameters 640 in Success Request [Bug 203] 641 * added support for sending EAP-AKA Notifications in error cases 642 * updated to use IEEE 802.11w/D2.0 for management frame protection 643 (still experimental) 644 * RADIUS server: added support for processing duplicate messages 645 (retransmissions from RADIUS client) by replying with the previous 646 reply 647 648 2006-11-24 - v0.5.6 649 * added support for configuring and controlling multiple BSSes per 650 radio interface (bss=<ifname> in hostapd.conf); this is only 651 available with Devicescape and test driver interfaces 652 * fixed PMKSA cache update in the end of successful RSN 653 pre-authentication 654 * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID 655 for each STA based on RADIUS Access-Accept attributes); this requires 656 VLAN support from the kernel driver/802.11 stack and this is 657 currently only available with Devicescape and test driver interfaces 658 * driver_madwifi: fixed configuration of unencrypted modes (plaintext 659 and IEEE 802.1X without WEP) 660 * removed STAKey handshake since PeerKey handshake has replaced it in 661 IEEE 802.11ma and there are no known deployments of STAKey 662 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 663 draft (draft-ietf-emu-eap-gpsk-01.txt) 664 * added preliminary implementation of IEEE 802.11w/D1.0 (management 665 frame protection) 666 (Note: this requires driver support to work properly.) 667 (Note2: IEEE 802.11w is an unapproved draft and subject to change.) 668 * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM) 669 * hlr_auc_gw: added support for reading per-IMSI Milenage keys and 670 parameters from a text file to make it possible to implement proper 671 GSM/UMTS authentication server for multiple SIM/USIM cards using 672 EAP-SIM/EAP-AKA 673 * fixed session timeout processing with drivers that do not use 674 ieee802_11.c (e.g., madwifi) 675 676 2006-08-27 - v0.5.5 677 * added 'hostapd_cli new_sta <addr>' command for adding a new STA into 678 hostapd (e.g., to initialize wired network authentication based on an 679 external signal) 680 * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when 681 using WPA2 even if PMKSA caching is not used 682 * added -P<pid file> argument for hostapd to write the current process 683 id into a file 684 * added support for RADIUS Authentication Server MIB (RFC 2619) 685 686 2006-06-20 - v0.5.4 687 * fixed nt_password_hash build [Bug 144] 688 * added PeerKey handshake implementation for IEEE 802.11e 689 direct link setup (DLS) to replace STAKey handshake 690 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK, 691 draft-clancy-emu-eap-shared-secret-00.txt) 692 * fixed a segmentation fault when RSN pre-authentication was completed 693 successfully [Bug 152] 694 695 2006-04-27 - v0.5.3 696 * do not build nt_password_hash and hlr_auc_gw by default to avoid 697 requiring a TLS library for a successful build; these programs can be 698 build with 'make nt_password_hash' and 'make hlr_auc_gw' 699 * added a new configuration option, eapol_version, that can be used to 700 set EAPOL version to 1 (default is 2) to work around broken client 701 implementations that drop EAPOL frames which use version number 2 702 [Bug 89] 703 * added support for EAP-SAKE (no EAP method number allocated yet, so 704 this is using the same experimental type 255 as EAP-PSK) 705 * fixed EAP-MSCHAPv2 message length validation 706 707 2006-03-19 - v0.5.2 708 * fixed stdarg use in hostapd_logger(): if both stdout and syslog 709 logging was enabled, hostapd could trigger a segmentation fault in 710 vsyslog on some CPU -- C library combinations 711 * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external 712 program to make it easier to use for implementing real SS7 gateway; 713 eap_sim_db is not anymore used as a file name for GSM authentication 714 triplets; instead, it is path to UNIX domain socket that will be used 715 to communicate with the external gateway program (e.g., hlr_auc_gw) 716 * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses 717 local information (GSM authentication triplets from a text file and 718 hardcoded AKA authentication data); this can be used to test EAP-SIM 719 and EAP-AKA 720 * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw 721 to make it possible to test EAP-AKA with real USIM cards (this is 722 disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw 723 to enable this) 724 * driver_madwifi: added support for getting station RSN IE from 725 madwifi-ng svn r1453 and newer; this fixes RSN that was apparently 726 broken with earlier change (r1357) in the driver 727 * changed EAP method registration to use a dynamic list of methods 728 instead of a static list generated at build time 729 * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE) 730 [Bug 125] 731 * added ap_max_inactivity configuration parameter 732 733 2006-01-29 - v0.5.1 734 * driver_test: added better support for multiple APs and STAs by using 735 a directory with sockets that include MAC address for each device in 736 the name (test_socket=DIR:/tmp/test) 737 * added support for EAP expanded type (vendor specific EAP methods) 738 739 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases) 740 * added experimental STAKey handshake implementation for IEEE 802.11e 741 direct link setup (DLS); note: this is disabled by default in both 742 build and runtime configuration (can be enabled with CONFIG_STAKEY=y 743 and stakey=1) 744 * added support for EAP methods to use callbacks to external programs 745 by buffering a pending request and processing it after the EAP method 746 is ready to continue 747 * improved EAP-SIM database interface to allow external request to GSM 748 HLR/AuC without blocking hostapd process 749 * added support for using EAP-SIM pseudonyms and fast re-authentication 750 * added support for EAP-AKA in the integrated EAP authenticator 751 * added support for matching EAP identity prefixes (e.g., "1"*) in EAP 752 user database to allow EAP-SIM/AKA selection without extra roundtrip 753 for EAP-Nak negotiation 754 * added support for storing EAP user password as NtPasswordHash instead 755 of plaintext password when using MSCHAP or MSCHAPv2 for 756 authentication (hash:<16-octet hex value>); added nt_password_hash 757 tool for hashing password to generate NtPasswordHash 758 759 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases) 760 * driver_wired: fixed EAPOL sending to optionally use PAE group address 761 as the destination instead of supplicant MAC address; this is 762 disabled by default, but should be enabled with use_pae_group_addr=1 763 in configuration file if the wired interface is used by only one 764 device at the time (common switch configuration) 765 * driver_madwifi: configure driver to use TKIP countermeasures in order 766 to get correct behavior (IEEE 802.11 association failing; previously, 767 association succeeded, but hostpad forced disassociation immediately) 768 * driver_madwifi: added support for madwifi-ng 769 770 2005-10-27 - v0.4.6 771 * added support for replacing user identity from EAP with RADIUS 772 User-Name attribute from Access-Accept message, if that is included, 773 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get 774 tunneled identity into accounting messages when the RADIUS server 775 does not support better way of doing this with Class attribute) 776 * driver_madwifi: fixed EAPOL packet receive for configuration where 777 ath# is part of a bridge interface 778 * added a configuration file and log analyzer script for logwatch 779 * fixed EAPOL state machine step function to process all state 780 transitions before processing new events; this resolves a race 781 condition in which EAPOL-Start message could trigger hostapd to send 782 two EAP-Response/Identity frames to the authentication server 783 784 2005-09-25 - v0.4.5 785 * added client CA list to the TLS certificate request in order to make 786 it easier for the client to select which certificate to use 787 * added experimental support for EAP-PSK 788 * added support for WE-19 (hostap, madwifi) 789 790 2005-08-21 - v0.4.4 791 * fixed build without CONFIG_RSN_PREAUTH 792 * fixed FreeBSD build 793 794 2005-06-26 - v0.4.3 795 * fixed PMKSA caching to copy User-Name and Class attributes so that 796 RADIUS accounting gets correct information 797 * start RADIUS accounting only after successful completion of WPA 798 4-Way Handshake if WPA-PSK is used 799 * fixed PMKSA caching for the case where STA (re)associates without 800 first disassociating 801 802 2005-06-12 - v0.4.2 803 * EAP-PAX is now registered as EAP type 46 804 * fixed EAP-PAX MAC calculation 805 * fixed EAP-PAX CK and ICK key derivation 806 * renamed eap_authenticator configuration variable to eap_server to 807 better match with RFC 3748 (EAP) terminology 808 * driver_test: added support for testing hostapd with wpa_supplicant 809 by using test driver interface without any kernel drivers or network 810 cards 811 812 2005-05-22 - v0.4.1 813 * fixed RADIUS server initialization when only auth or acct server 814 is configured and the other one is left empty 815 * driver_madwifi: added support for RADIUS accounting 816 * driver_madwifi: added preliminary support for compiling against 'BSD' 817 branch of madwifi CVS tree 818 * driver_madwifi: fixed pairwise key removal to allow WPA reauth 819 without disassociation 820 * added support for reading additional certificates from PKCS#12 files 821 and adding them to the certificate chain 822 * fixed RADIUS Class attribute processing to only use Access-Accept 823 packets to update Class; previously, other RADIUS authentication 824 packets could have cleared Class attribute 825 * added support for more than one Class attribute in RADIUS packets 826 * added support for verifying certificate revocation list (CRL) when 827 using integrated EAP authenticator for EAP-TLS; new hostapd.conf 828 options 'check_crl'; CRL must be included in the ca_cert file for now 829 830 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases) 831 * added support for including network information into 832 EAP-Request/Identity message (ASCII-0 (nul) in eap_message) 833 (e.g., to implement draft-adrange-eap-network-discovery-07.txt) 834 * fixed a bug which caused some RSN pre-authentication cases to use 835 freed memory and potentially crash hostapd 836 * fixed private key loading for cases where passphrase is not set 837 * added support for sending TLS alerts and aborting authentication 838 when receiving a TLS alert 839 * fixed WPA2 to add PMKSA cache entry when using integrated EAP 840 authenticator 841 * fixed PMKSA caching (EAP authentication was not skipped correctly 842 with the new state machine changes from IEEE 802.1X draft) 843 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr, 844 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs 845 to be added to .config to include IPv6 support); for RADIUS server, 846 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses 847 in RADIUS clients file can then use IPv6 format 848 * added experimental support for EAP-PAX 849 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with 850 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch]) 851 852 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases) 853 854 2005-01-23 - v0.3.5 855 * added support for configuring a forced PEAP version based on the 856 Phase 1 identity 857 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV 858 to terminate authentication 859 * fixed EAP identifier duplicate processing with the new IEEE 802.1X 860 draft 861 * clear accounting data in the driver when starting a new accounting 862 session 863 * driver_madwifi: filter wireless events based on ifindex to allow more 864 than one network interface to be used 865 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt 866 setting if the packet does not pass MIC verification (e.g., due to 867 incorrect PSK); previously, message 1/4 was not tried again if an 868 invalid message 2/4 was received 869 * fixed reconfiguration of RADIUS client retransmission timer when 870 adding a new message to the pending list; previously, timer was not 871 updated at this point and if there was a pending message with long 872 time for the next retry, the new message needed to wait that long for 873 its first retry, too 874 875 2005-01-09 - v0.3.4 876 * added support for configuring multiple allowed EAP types for Phase 2 877 authentication (EAP-PEAP, EAP-TTLS) 878 * fixed EAPOL-Start processing to trigger WPA reauthentication 879 (previously, only EAPOL authentication was done) 880 881 2005-01-02 - v0.3.3 882 * added support for EAP-PEAP in the integrated EAP authenticator 883 * added support for EAP-GTC in the integrated EAP authenticator 884 * added support for configuring list of EAP methods for Phase 1 so that 885 the integrated EAP authenticator can, e.g., use the wildcard entry 886 for EAP-TLS and EAP-PEAP 887 * added support for EAP-TTLS in the integrated EAP authenticator 888 * added support for EAP-SIM in the integrated EAP authenticator 889 * added support for using hostapd as a RADIUS authentication server 890 with the integrated EAP authenticator taking care of EAP 891 authentication (new hostapd.conf options: radius_server_clients and 892 radius_server_auth_port); this is not included in default build; use 893 CONFIG_RADIUS_SERVER=y in .config to include 894 895 2004-12-19 - v0.3.2 896 * removed 'daemonize' configuration file option since it has not really 897 been used at all for more than year 898 * driver_madwifi: fixed group key setup and added get_ssid method 899 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator 900 901 2004-12-12 - v0.3.1 902 * added support for integrated EAP-TLS authentication (new hostapd.conf 903 variables: ca_cert, server_cert, private_key, private_key_passwd); 904 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without 905 external RADIUS server 906 * added support for reading PKCS#12 (PFX) files (as a replacement for 907 PEM/DER) to get certificate and private key (CONFIG_PKCS12) 908 909 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases) 910 * added support for Acct-{Input,Output}-Gigawords 911 * added support for Event-Timestamp (in RADIUS Accounting-Requests) 912 * added support for RADIUS Authentication Client MIB (RFC2618) 913 * added support for RADIUS Accounting Client MIB (RFC2620) 914 * made EAP re-authentication period configurable (eap_reauth_period) 915 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication 916 * fixed EAPOL state machine to stop if STA is removed during 917 eapol_sm_step(); this fixes at least one segfault triggering bug with 918 IEEE 802.11i pre-authentication 919 * added support for multiple WPA pre-shared keys (e.g., one for each 920 client MAC address or keys shared by a group of clients); 921 new hostapd.conf field wpa_psk_file for setting path to a text file 922 containing PSKs, see hostapd.wpa_psk for an example 923 * added support for multiple driver interfaces to allow hostapd to be 924 used with other drivers 925 * added wired authenticator driver interface (driver=wired in 926 hostapd.conf, see wired.conf for example configuration) 927 * added madwifi driver interface (driver=madwifi in hostapd.conf, see 928 madwifi.conf for example configuration; Note: include files from 929 madwifi project is needed for building and a configuration file, 930 .config, needs to be created in hostapd directory with 931 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd 932 build) 933 * fixed an alignment issue that could cause SHA-1 to fail on some 934 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit 935 align variables) 936 * fixed RADIUS reconnection after an error in sending interim 937 accounting packets 938 * added hostapd control interface for external programs and an example 939 CLI, hostapd_cli (like wpa_cli for wpa_supplicant) 940 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib', 941 'hostapd_cli sta <addr>') 942 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11) 943 * added support for strict GTK rekeying (wpa_strict_rekey in 944 hostapd.conf) 945 * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178 946 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to 947 IEEE 802.11F-2003) 948 * added Prism54 driver interface (driver=prism54 in hostapd.conf; 949 note: .config needs to be created in hostapd directory with 950 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd 951 build) 952 * dual-licensed hostapd (GPLv2 and BSD licenses) 953 * fixed RADIUS accounting to generate a new session id for cases where 954 a station reassociates without first being complete deauthenticated 955 * fixed STA disassociation handler to mark next timeout state to 956 deauthenticate the station, i.e., skip long wait for inactivity poll 957 and extra disassociation, if the STA disassociates without 958 deauthenticating 959 * added integrated EAP authenticator that can be used instead of 960 external RADIUS authentication server; currently, only EAP-MD5 is 961 supported, so this cannot yet be used for key distribution; the EAP 962 method interface is generic, though, so adding new EAP methods should 963 be straightforward; new hostapd.conf variables: 'eap_authenticator' 964 and 'eap_user_file'; this obsoletes "minimal authentication server" 965 ('minimal_eap' in hostapd.conf) which is now removed 966 * added support for FreeBSD and driver interface for the BSD net80211 967 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in 968 .config); please note that some of the required kernel mods have not 969 yet been committed 970 971 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases) 972 * fixed some accounting cases where Accounting-Start was sent when 973 IEEE 802.1X port was being deauthorized 974 975 2004-06-20 - v0.2.3 976 * modified RADIUS client to re-connect the socket in case of certain 977 error codes that are generated when a network interface state is 978 changes (e.g., when IP address changes or the interface is set UP) 979 * fixed couple of cases where EAPOL state for a station was freed 980 twice causing a segfault for hostapd 981 * fixed couple of bugs in processing WPA deauthentication (freed data 982 was used) 983 984 2004-05-31 - v0.2.2 985 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM) 986 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix 987 cases where STAs dropped multicast frames as replay attacks 988 * added support for copying RADIUS Attribute 'Class' from 989 authentication messages into accounting messages 990 * send canned EAP failure if RADIUS server sends Access-Reject without 991 EAP message (previously, Supplicant was not notified in this case) 992 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do 993 not start EAPOL state machines if the STA selected to use WPA-PSK) 994 995 2004-05-06 - v0.2.1 996 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality 997 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA 998 (i.e., IEEE 802.11i/D3.0) 999 - supports WPA-only, RSN-only, and mixed WPA/RSN mode 1000 - both WPA-PSK and WPA-RADIUS/EAP are supported 1001 - PMKSA caching and pre-authentication 1002 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase, 1003 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey, 1004 rsn_preauth, rsn_preauth_interfaces 1005 * fixed interim accounting to remove any pending accounting messages 1006 to the STA before sending a new one 1007 1008 2004-02-15 - v0.2.0 1009 * added support for Acct-Interim-Interval: 1010 - draft-ietf-radius-acct-interim-01.txt 1011 - use Acct-Interim-Interval attribute from Access-Accept if local 1012 'radius_acct_interim_interval' is not set 1013 - allow different update intervals for each STA 1014 * fixed event loop to call signal handlers only after returning from 1015 the real signal handler 1016 * reset sta->timeout_next after successful association to make sure 1017 that the previously registered inactivity timer will not remove the 1018 STA immediately (e.g., if STA deauthenticates and re-associates 1019 before the timer is triggered). 1020 * added new hostapd.conf variable, nas_identifier, that can be used to 1021 add an optional RADIUS Attribute, NAS-Identifier, into authentication 1022 and accounting messages 1023 * added support for Accounting-On and Accounting-Off messages 1024 * fixed accounting session handling to send Accounting-Start only once 1025 per session and not to send Accounting-Stop if the session was not 1026 initialized properly 1027 * fixed Accounting-Stop statistics in cases where the message was 1028 previously sent after the kernel entry for the STA (and/or IEEE 1029 802.1X data) was removed 1030 1031 1032 Note: 1033 1034 Older changes up to and including v0.1.0 are included in the ChangeLog 1035 of the Host AP driver. 1036
