See hostapd.conf for config info. 244 * Delay STA entry removal until Deauth/Disassoc TX status in AP mode. 245 This allows the driver to use PS buffering of Deauthentication and 246 Disassociation frames when the STA is in power save sleep. Only 247 available with drivers that provide TX status events for Deauth/ 248 Disassoc frames (nl80211). 249 * Allow PMKSA caching to be disabled on the Authenticator. See 250 hostap.conf config parameter disable_pmksa_caching. 251 * atheros: Add support for IEEE 802.11w configuration. 252 * bsd: Add support for setting HT values in IFM_MMASK. 253 * Allow client isolation to be configured with ap_isolate.

It works in the same way as new AP settings received 276 from an ER. 277 - Many WPS/WPS ER commands - see WPS/WPS ER sections for details. 278 - Add command get version, that returns hostapd version string. 279 * WNM: Add BSS Transition Management Request for ESS Disassoc Imminent. 280 Use hostapd_cli ess_disassoc (STA addr) (URL) to send the 281 notification to the STA. 282 * Allow AP mode to disconnect STAs based on low ACK condition (when 283 the data connection is not working properly, e.g., due to the STA 284 going outside the range of the AP). Disabled by default, enable by 285 config option disassoc_low_ack. 286 * Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad 287 config file. 288 * WPS: 289 - Send AP Settings as a wrapped Credential attribute to ctrl_iface 290 in WPS-NEW-AP-SETTINGS. 291 - Dispatch more WPS events through hostapd ctrl_iface. 292 - Add mechanism for indicating non-standard WPS errors. 293 - Change concurrent radio AP to use only one WPS UPnP instance. 294 - Add wps_check_pin command for processing PIN from user input. 295 UIs can use this command to process a PIN entered by a user and to 296 validate the checksum digit (if present). 297 - Add hostap_cli get_config command to display current AP config. 298 - Add new hostapd_cli command, wps_ap_pin, to manage AP PIN at 299 runtime and support dynamic AP PIN management. 300 - Disable AP PIN after 10 consecutive failures. Slow down attacks 301 on failures up to 10. 302 - Allow AP to start in Enrollee mode without AP PIN for probing, 303 to be compatible with Windows 7. 304 - Add Config Error into WPS-FAIL events to provide more info 305 to the user on how to resolve the issue. 306 - When controlling multiple interfaces: 307 - apply WPS commands to all interfaces configured to use WPS 308 - apply WPS config changes to all interfaces that use WPS 309 - when an attack is detected on any interface, disable AP PIN on 310 all interfaces 311 * WPS ER: 312 - Show SetSelectedRegistrar events as ctrl_iface events. 313 - Add special AP Setup Locked mode to allow read only ER. 314 ap_setup_locked=2 can now be used to enable a special mode where 315 WPS ER can learn the current AP settings, but cannot change them. 316 * WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2) 317 - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool 318 for testing protocol extensibility. 319 - Add build option CONFIG_WPS_STRICT to allow disabling of WPS 320 workarounds. 321 - Add support for AuthorizedMACs attribute. 322 * TDLS: 323 - Allow TDLS use or TDLS channel switching in the BSS to be 324 prohibited in the BSS, using config params tdls_prohibit and 325 tdls_prohibit_chan_switch. 326 * EAP server: Add support for configuring fragment size (see 327 fragment_size in hostapd.conf). 328 * wlantest: Add a tool wlantest for IEEE802.11 protocol testing. 329 wlantest can be used to capture frames from a monitor interface 330 for realtime capturing or from pcap files for offline analysis. 331 * Interworking: Support added for 802.11u. Enable in .config with 332 CONFIG_INTERWORKING. See hostapd.conf for config parameters for 333 interworking. 334 * Android: Add build and runtime support for Android hostapd. 335 * Add a new debug message level for excessive information. Use 336 -ddd to enable. 337 * TLS: Add support for tls_disable_time_checks=1 in client mode. 338 * Internal TLS: 339 - Add support for TLS v1.1 (RFC 4346). Enable with build parameter 340 CONFIG_TLSV11. 341 - Add domainComponent parser for X.509 names 342 * Reorder some IEs to get closer to IEEE 802.11 standard. Move 343 WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames. 344 Move HT IEs to be later in (Re)Assoc Resp. 345 * Many bugfixes. 346 347 2010-04-18 - v0.7.2 348 * fix WPS internal Registrar use when an external Registrar is also 349 active 350 * bsd: Cleaned up driver wrapper and added various low-level 351 configuration options 352 * TNC: fixed issues with fragmentation 353 * EAP-TNC: add Flags field into fragment acknowledgement (needed to 354 interoperate with other implementations;

part configurable with CONFIG_NO_* build 422 options) 423 * use shared driver wrapper files with wpa_supplicant 424 * driver_nl80211: multiple updates to provide support for new Linux 425 nl80211/mac80211 functionality 426 * updated management frame protection to use IEEE Std 802.11w-2009 427 * fixed number of small WPS issues and added workarounds to 428 interoperate with common deployed broken implementations 429 * added some IEEE 802.11n co-existence rules to disable 40 MHz channels 430 or modify primary/secondary channels if needed based on neighboring 431 networks 432 * added support for NFC out-of-band mechanism with WPS 433 * added preliminary support for IEEE 802.11r RIC processing 434 435 2009-01-06 - v0.6.7 436 * added support for Wi-Fi Protected Setup (WPS) 437 (hostapd can now be configured to act as an integrated WPS Registrar 438 and provision credentials for WPS Enrollees using PIN and PBC 439 methods; external wireless Registrar can configure the AP, but 440 external WLAN Manager Registrars are not supported); WPS support can 441 be enabled by adding CONFIG_WPS=y into .config and setting the 442 runtime configuration variables in hostapd.conf (see WPS section in 443 the example configuration file); new hostapd_cli commands wps_pin and 444 wps_pbc are used to configure WPS negotiation; see README-WPS for 445 more details 446 * added IEEE 802.11n HT capability configuration (ht_capab) 447 * added support for generating Country IE based on nl80211 regulatory 448 information (added if ieee80211d=1 in configuration) 449 * fixed WEP authentication (both Open System and Shared Key) with 450 mac80211 451 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf) 452 * added support for using driver_test over UDP socket 453 * changed EAP-GPSK to use the IANA assigned EAP method type 51 454 * updated management frame protection to use IEEE 802.11w/D7.0 455 * fixed retransmission of EAP requests if no response is received 456 457 2008-11-23 - v0.6.6 458 * added a new configuration option, wpa_ptk_rekey, that can be used to 459 enforce frequent PTK rekeying, e.g., to mitigate some attacks against 460 TKIP deficiencies 461 * updated OpenSSL code for EAP-FAST to use an updated version of the 462 session ticket overriding API that was included into the upstream 463 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is 464 needed with that version anymore) 465 * changed channel flags configuration to read the information from 466 the driver (e.g., via driver_nl80211 when using mac80211) instead of 467 using hostapd as the source of the regulatory information (i.e., 468 information from CRDA is now used with mac80211); this allows 5 GHz 469 channels to be used with hostapd (if allowed in the current 470 regulatory domain) 471 * fixed EAP-TLS message processing for the last TLS message if it is 472 large enough to require fragmentation (e.g., if a large Session 473 Ticket data is included) 474 * fixed listen interval configuration for nl80211 drivers 475 476 2008-11-01 - v0.6.5 477 * added support for SHA-256 as X.509 certificate digest when using the 478 internal X.509/TLSv1 implementation 479 * fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer 480 identity lengths) 481 * fixed internal TLSv1 implementation for abbreviated handshake (used 482 by EAP-FAST server) 483 * added support for setting VLAN ID for STAs based on local MAC ACL 484 (accept_mac_file) as an alternative for RADIUS server-based 485 configuration 486 * updated management frame protection to use IEEE 802.11w/D6.0 487 (adds a new association ping to protect against unauthenticated 488 authenticate or (re)associate request frames dropping association) 489 * added support for using SHA256-based stronger key derivation for WPA2 490 (IEEE 802.11w) 491 * added new "driver wrapper" for RADIUS-only configuration 492 (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config) 493 * fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2) 494 is enabled in configuration 495 * changed EAP-FAST configuration to use separate fields for A-ID and 496 A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed 497 16-octet len binary value for better interoperability with some peer 498 implementations; eap_fast_a_id is now configured as a hex string 499 * driver_nl80211: Updated to match the current Linux mac80211 AP mode 500 configuration (wireless-testing.git and Linux kernel releases 501 starting from 2.6.29) 502 503 2008-08-10 - v0.6.4 504 * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2 505 Identity Request if identity is already known 506 * added support for EAP Sequences in EAP-FAST Phase 2 507 * added support for EAP-TNC (Trusted Network Connect) 508 (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST 509 changes needed to run two methods in sequence (IF-T) and the IF-IMV 510 and IF-TNCCS interfaces from TNCS) 511 * added support for optional cryptobinding with PEAPv0 512 * added fragmentation support for EAP-TNC 513 * added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled) 514 data 515 * added support for opportunistic key caching (OKC) 516 517 2008-02-22 - v0.6.3 518 * fixed Reassociation Response callback processing when using internal 519 MLME (driver_{hostap,nl80211,test}.c) 520 * updated FT support to use the latest draft, IEEE 802.11r/D9.0 521 * copy optional Proxy-State attributes into RADIUS response when acting 522 as a RADIUS authentication server 523 * fixed EAPOL state machine to handle a case in which no response is 524 received from the RADIUS authentication server; previous version 525 could have triggered a crash in some cases after a timeout 526 * fixed EAP-SIM/AKA realm processing to allow decorated usernames to 527 be used 528 * added a workaround for EAP-SIM/AKA peers that include incorrect null 529 termination in the username 530 * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER 531 attribute in notification messages only when using fast 532 reauthentication 533 * fixed EAP-SIM Start response processing for fast reauthentication 534 case 535 * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST} 536 phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method 537 538 2008-01-01 - v0.6.2 539 * fixed EAP-SIM and EAP-AKA message parser to validate attribute 540 lengths properly to avoid potential crash caused by invalid messages 541 * added data structure for storing allocated buffers (struct wpabuf); 542 this does not affect hostapd usage, but many of the APIs changed 543 and various interfaces (e.g., EAP) is not compatible with old 544 versions 545 * added support for protecting EAP-AKA/Identity messages with 546 AT_CHECKCODE (optional feature in RFC 4187) 547 * added support for protected result indication with AT_RESULT_IND for 548 EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1) 549 * added support for configuring EAP-TTLS phase 2 non-EAP methods in 550 EAP server configuration; previously all four were enabled for every 551 phase 2 user, now all four are disabled by default and need to be 552 enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP, 553 TTLS-MSCHAPV2 554 * removed old debug printing mechanism and the related 'debug' 555 parameter in the configuration file; debug verbosity is now set with 556 -d (or -dd) command line arguments 557 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt); 558 only shared key/password authentication is supported in this version 559 560 2007-11-24 - v0.6.1 561 * added experimental, integrated TLSv1 server implementation with the 562 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by 563 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in 564 .config); this can be useful, e.g., if the target system does not 565 have a suitable TLS library and a minimal code size is required 566 * added support for EAP-FAST server method to the integrated EAP 567 server 568 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 569 draft (draft-ietf-emu-eap-gpsk-07.txt) 570 * added a new configuration parameter, rsn_pairwise, to allow different 571 pairwise cipher suites to be enabled for WPA and RSN/WPA2 572 (note: if wpa_pairwise differs from rsn_pairwise, the driver will 573 either need to support this or will have to use the WPA/RSN IEs from 574 hostapd; currently, the included madwifi and bsd driver interfaces do 575 not have support for this) 576 * updated FT support to use the latest draft, IEEE 802.11r/D8.0 577 578 2007-05-28 - v0.6.0 579 * added experimental IEEE 802.11r/D6.0 support 580 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48 581 * updated EAP-PSK to use the IANA-allocated EAP type 47 582 * fixed EAP-PSK bit ordering of the Flags field 583 * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs 584 by reading wpa_psk_file [Bug 181] 585 * fixed EAP-TTLS AVP parser processing for too short AVP lengths 586 * fixed IPv6 connection to RADIUS accounting server 587 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 588 draft (draft-ietf-emu-eap-gpsk-04.txt) 589 * hlr_auc_gw: read GSM triplet file into memory and rotate through the 590 entries instead of only using the same three triplets every time 591 (this does not work properly with tests using multiple clients, but 592 provides bit better triplet data for testing a single client; anyway, 593 if a better quality triplets are needed, GSM-Milenage should be used 594 instead of hardcoded triplet file) 595 * fixed EAP-MSCHAPv2 server to use a space between S and M parameters 596 in Success Request [Bug 203] 597 * added support for sending EAP-AKA Notifications in error cases 598 * updated to use IEEE 802.11w/D2.0 for management frame protection 599 (still experimental) 600 * RADIUS server: added support for processing duplicate messages 601 (retransmissions from RADIUS client) by replying with the previous 602 reply 603 604 2006-11-24 - v0.5.6 605 * added support for configuring and controlling multiple BSSes per 606 radio interface (bss=<ifname> in hostapd.conf); this is only 607 available with Devicescape and test driver interfaces 608 * fixed PMKSA cache update in the end of successful RSN 609 pre-authentication 610 * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID 611 for each STA based on RADIUS Access-Accept attributes); this requires 612 VLAN support from the kernel driver/802.11 stack and this is 613 currently only available with Devicescape and test driver interfaces 614 * driver_madwifi: fixed configuration of unencrypted modes (plaintext 615 and IEEE 802.1X without WEP) 616 * removed STAKey handshake since PeerKey handshake has replaced it in 617 IEEE 802.11ma and there are no known deployments of STAKey 618 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 619 draft (draft-ietf-emu-eap-gpsk-01.txt) 620 * added preliminary implementation of IEEE 802.11w/D1.0 (management 621 frame protection) 622 (Note: this requires driver support to work properly.) 623 (Note2: IEEE 802.11w is an unapproved draft and subject to change.) 624 * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM) 625 * hlr_auc_gw: added support for reading per-IMSI Milenage keys and 626 parameters from a text file to make it possible to implement proper 627 GSM/UMTS authentication server for multiple SIM/USIM cards using 628 EAP-SIM/EAP-AKA 629 * fixed session timeout processing with drivers that do not use 630 ieee802_11.c (e.g., madwifi) 631 632 2006-08-27 - v0.5.5 633 * added 'hostapd_cli new_sta <addr>' command for adding a new STA into 634 hostapd (e.g., to initialize wired network authentication based on an 635 external signal) 636 * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when 637 using WPA2 even if PMKSA caching is not used 638 * added -P<pid file> argument for hostapd to write the current process 639 id into a file 640 * added support for RADIUS Authentication Server MIB (RFC 2619) 641 642 2006-06-20 - v0.5.4 643 * fixed nt_password_hash build [Bug 144] 644 * added PeerKey handshake implementation for IEEE 802.11e 645 direct link setup (DLS) to replace STAKey handshake 646 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK, 647 draft-clancy-emu-eap-shared-secret-00.txt) 648 * fixed a segmentation fault when RSN pre-authentication was completed 649 successfully [Bug 152] 650 651 2006-04-27 - v0.5.3 652 * do not build nt_password_hash and hlr_auc_gw by default to avoid 653 requiring a TLS library for a successful build; these programs can be 654 build with 'make nt_password_hash' and 'make hlr_auc_gw' 655 * added a new configuration option, eapol_version, that can be used to 656 set EAPOL version to 1 (default is 2) to work around broken client 657 implementations that drop EAPOL frames which use version number 2 658 [Bug 89] 659 * added support for EAP-SAKE (no EAP method number allocated yet, so 660 this is using the same experimental type 255 as EAP-PSK) 661 * fixed EAP-MSCHAPv2 message length validation 662 663 2006-03-19 - v0.5.2 664 * fixed stdarg use in hostapd_logger(): if both stdout and syslog 665 logging was enabled, hostapd could trigger a segmentation fault in 666 vsyslog on some CPU -- C library combinations 667 * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external 668 program to make it easier to use for implementing real SS7 gateway; 669 eap_sim_db is not anymore used as a file name for GSM authentication 670 triplets; instead, it is path to UNIX domain socket that will be used 671 to communicate with the external gateway program (e.g., hlr_auc_gw) 672 * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses 673 local information (GSM authentication triplets from a text file and 674 hardcoded AKA authentication data); this can be used to test EAP-SIM 675 and EAP-AKA 676 * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw 677 to make it possible to test EAP-AKA with real USIM cards (this is 678 disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw 679 to enable this) 680 * driver_madwifi: added support for getting station RSN IE from 681 madwifi-ng svn r1453 and newer; this fixes RSN that was apparently 682 broken with earlier change (r1357) in the driver 683 * changed EAP method registration to use a dynamic list of methods 684 instead of a static list generated at build time 685 * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE) 686 [Bug 125] 687 * added ap_max_inactivity configuration parameter 688 689 2006-01-29 - v0.5.1 690 * driver_test: added better support for multiple APs and STAs by using 691 a directory with sockets that include MAC address for each device in 692 the name (test_socket=DIR:/tmp/test) 693 * added support for EAP expanded type (vendor specific EAP methods) 694 695 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases) 696 * added experimental STAKey handshake implementation for IEEE 802.11e 697 direct link setup (DLS); note: this is disabled by default in both 698 build and runtime configuration (can be enabled with CONFIG_STAKEY=y 699 and stakey=1) 700 * added support for EAP methods to use callbacks to external programs 701 by buffering a pending request and processing it after the EAP method 702 is ready to continue 703 * improved EAP-SIM database interface to allow external request to GSM 704 HLR/AuC without blocking hostapd process 705 * added support for using EAP-SIM pseudonyms and fast re-authentication 706 * added support for EAP-AKA in the integrated EAP authenticator 707 * added support for matching EAP identity prefixes (e.g., "1"*) in EAP 708 user database to allow EAP-SIM/AKA selection without extra roundtrip 709 for EAP-Nak negotiation 710 * added support for storing EAP user password as NtPasswordHash instead 711 of plaintext password when using MSCHAP or MSCHAPv2 for 712 authentication (hash:<16-octet hex value>); added nt_password_hash 713 tool for hashing password to generate NtPasswordHash 714 715 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases) 716 * driver_wired: fixed EAPOL sending to optionally use PAE group address 717 as the destination instead of supplicant MAC address; this is 718 disabled by default, but should be enabled with use_pae_group_addr=1 719 in configuration file if the wired interface is used by only one 720 device at the time (common switch configuration) 721 * driver_madwifi: configure driver to use TKIP countermeasures in order 722 to get correct behavior (IEEE 802.11 association failing; previously, 723 association succeeded, but hostpad forced disassociation immediately) 724 * driver_madwifi: added support for madwifi-ng 725 726 2005-10-27 - v0.4.6 727 * added support for replacing user identity from EAP with RADIUS 728 User-Name attribute from Access-Accept message, if that is included, 729 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get 730 tunneled identity into accounting messages when the RADIUS server 731 does not support better way of doing this with Class attribute) 732 * driver_madwifi: fixed EAPOL packet receive for configuration where 733 ath# is part of a bridge interface 734 * added a configuration file and log analyzer script for logwatch 735 * fixed EAPOL state machine step function to process all state 736 transitions before processing new events; this resolves a race 737 condition in which EAPOL-Start message could trigger hostapd to send 738 two EAP-Response/Identity frames to the authentication server 739 740 2005-09-25 - v0.4.5 741 * added client CA list to the TLS certificate request in order to make 742 it easier for the client to select which certificate to use 743 * added experimental support for EAP-PSK 744 * added support for WE-19 (hostap, madwifi) 745 746 2005-08-21 - v0.4.4 747 * fixed build without CONFIG_RSN_PREAUTH 748 * fixed FreeBSD build 749 750 2005-06-26 - v0.4.3 751 * fixed PMKSA caching to copy User-Name and Class attributes so that 752 RADIUS accounting gets correct information 753 * start RADIUS accounting only after successful completion of WPA 754 4-Way Handshake if WPA-PSK is used 755 * fixed PMKSA caching for the case where STA (re)associates without 756 first disassociating 757 758 2005-06-12 - v0.4.2 759 * EAP-PAX is now registered as EAP type 46 760 * fixed EAP-PAX MAC calculation 761 * fixed EAP-PAX CK and ICK key derivation 762 * renamed eap_authenticator configuration variable to eap_server to 763 better match with RFC 3748 (EAP) terminology 764 * driver_test: added support for testing hostapd with wpa_supplicant 765 by using test driver interface without any kernel drivers or network 766 cards 767 768 2005-05-22 - v0.4.1 769 * fixed RADIUS server initialization when only auth or acct server 770 is configured and the other one is left empty 771 * driver_madwifi: added support for RADIUS accounting 772 * driver_madwifi: added preliminary support for compiling against 'BSD' 773 branch of madwifi CVS tree 774 * driver_madwifi: fixed pairwise key removal to allow WPA reauth 775 without disassociation 776 * added support for reading additional certificates from PKCS#12 files 777 and adding them to the certificate chain 778 * fixed RADIUS Class attribute processing to only use Access-Accept 779 packets to update Class; previously, other RADIUS authentication 780 packets could have cleared Class attribute 781 * added support for more than one Class attribute in RADIUS packets 782 * added support for verifying certificate revocation list (CRL) when 783 using integrated EAP authenticator for EAP-TLS; new hostapd.conf 784 options 'check_crl'; CRL must be included in the ca_cert file for now 785 786 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases) 787 * added support for including network information into 788 EAP-Request/Identity message (ASCII-0 (nul) in eap_message) 789 (e.g., to implement draft-adrange-eap-network-discovery-07.txt) 790 * fixed a bug which caused some RSN pre-authentication cases to use 791 freed memory and potentially crash hostapd 792 * fixed private key loading for cases where passphrase is not set 793 * added support for sending TLS alerts and aborting authentication 794 when receiving a TLS alert 795 * fixed WPA2 to add PMKSA cache entry when using integrated EAP 796 authenticator 797 * fixed PMKSA caching (EAP authentication was not skipped correctly 798 with the new state machine changes from IEEE 802.1X draft) 799 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr, 800 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs 801 to be added to .config to include IPv6 support); for RADIUS server, 802 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses 803 in RADIUS clients file can then use IPv6 format 804 * added experimental support for EAP-PAX 805 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with 806 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch]) 807 808 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases) 809 810 2005-01-23 - v0.3.5 811 * added support for configuring a forced PEAP version based on the 812 Phase 1 identity 813 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV 814 to terminate authentication 815 * fixed EAP identifier duplicate processing with the new IEEE 802.1X 816 draft 817 * clear accounting data in the driver when starting a new accounting 818 session 819 * driver_madwifi: filter wireless events based on ifindex to allow more 820 than one network interface to be used 821 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt 822 setting if the packet does not pass MIC verification (e.g., due to 823 incorrect PSK); previously, message 1/4 was not tried again if an 824 invalid message 2/4 was received 825 * fixed reconfiguration of RADIUS client retransmission timer when 826 adding a new message to the pending list; previously, timer was not 827 updated at this point and if there was a pending message with long 828 time for the next retry, the new message needed to wait that long for 829 its first retry, too 830 831 2005-01-09 - v0.3.4 832 * added support for configuring multiple allowed EAP types for Phase 2 833 authentication (EAP-PEAP, EAP-TTLS) 834 * fixed EAPOL-Start processing to trigger WPA reauthentication 835 (previously, only EAPOL authentication was done) 836 837 2005-01-02 - v0.3.3 838 * added support for EAP-PEAP in the integrated EAP authenticator 839 * added support for EAP-GTC in the integrated EAP authenticator 840 * added support for configuring list of EAP methods for Phase 1 so that 841 the integrated EAP authenticator can, e.g., use the wildcard entry 842 for EAP-TLS and EAP-PEAP 843 * added support for EAP-TTLS in the integrated EAP authenticator 844 * added support for EAP-SIM in the integrated EAP authenticator 845 * added support for using hostapd as a RADIUS authentication server 846 with the integrated EAP authenticator taking care of EAP 847 authentication (new hostapd.conf options: radius_server_clients and 848 radius_server_auth_port); this is not included in default build; use 849 CONFIG_RADIUS_SERVER=y in .config to include 850 851 2004-12-19 - v0.3.2 852 * removed 'daemonize' configuration file option since it has not really 853 been used at all for more than year 854 * driver_madwifi: fixed group key setup and added get_ssid method 855 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator 856 857 2004-12-12 - v0.3.1 858 * added support for integrated EAP-TLS authentication (new hostapd.conf 859 variables: ca_cert, server_cert, private_key, private_key_passwd); 860 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without 861 external RADIUS server 862 * added support for reading PKCS#12 (PFX) files (as a replacement for 863 PEM/DER) to get certificate and private key (CONFIG_PKCS12) 864 865 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases) 866 * added support for Acct-{Input,Output}-Gigawords 867 * added support for Event-Timestamp (in RADIUS Accounting-Requests) 868 * added support for RADIUS Authentication Client MIB (RFC2618) 869 * added support for RADIUS Accounting Client MIB (RFC2620) 870 * made EAP re-authentication period configurable (eap_reauth_period) 871 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication 872 * fixed EAPOL state machine to stop if STA is removed during 873 eapol_sm_step(); this fixes at least one segfault triggering bug with 874 IEEE 802.11i pre-authentication 875 * added support for multiple WPA pre-shared keys (e.g., one for each 876 client MAC address or keys shared by a group of clients); 877 new hostapd.conf field wpa_psk_file for setting path to a text file 878 containing PSKs, see hostapd.wpa_psk for an example 879 * added support for multiple driver interfaces to allow hostapd to be 880 used with other drivers 881 * added wired authenticator driver interface (driver=wired in 882 hostapd.conf, see wired.conf for example configuration) 883 * added madwifi driver interface (driver=madwifi in hostapd.conf, see 884 madwifi.conf for example configuration; Note: include files from 885 madwifi project is needed for building and a configuration file, 886 .config, needs to be created in hostapd directory with 887 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd 888 build) 889 * fixed an alignment issue that could cause SHA-1 to fail on some 890 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit 891 align variables) 892 * fixed RADIUS reconnection after an error in sending interim 893 accounting packets 894 * added hostapd control interface for external programs and an example 895 CLI, hostapd_cli (like wpa_cli for wpa_supplicant) 896 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib', 897 'hostapd_cli sta <addr>') 898 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11) 899 * added support for strict GTK rekeying (wpa_strict_rekey in 900 hostapd.conf) 901 * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178 902 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to 903 IEEE 802.11F-2003) 904 * added Prism54 driver interface (driver=prism54 in hostapd.conf; 905 note: .config needs to be created in hostapd directory with 906 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd 907 build) 908 * dual-licensed hostapd (GPLv2 and BSD licenses) 909 * fixed RADIUS accounting to generate a new session id for cases where 910 a station reassociates without first being complete deauthenticated 911 * fixed STA disassociation handler to mark next timeout state to 912 deauthenticate the station, i.e., skip long wait for inactivity poll 913 and extra disassociation, if the STA disassociates without 914 deauthenticating 915 * added integrated EAP authenticator that can be used instead of 916 external RADIUS authentication server; currently, only EAP-MD5 is 917 supported, so this cannot yet be used for key distribution; the EAP 918 method interface is generic, though, so adding new EAP methods should 919 be straightforward; new hostapd.conf variables: 'eap_authenticator' 920 and 'eap_user_file'; this obsoletes "minimal authentication server" 921 ('minimal_eap' in hostapd.conf) which is now removed 922 * added support for FreeBSD and driver interface for the BSD net80211 923 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in 924 .config); please note that some of the required kernel mods have not 925 yet been committed 926 927 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases) 928 * fixed some accounting cases where Accounting-Start was sent when 929 IEEE 802.1X port was being deauthorized 930 931 2004-06-20 - v0.2.3 932 * modified RADIUS client to re-connect the socket in case of certain 933 error codes that are generated when a network interface state is 934 changes (e.g., when IP address changes or the interface is set UP) 935 * fixed couple of cases where EAPOL state for a station was freed 936 twice causing a segfault for hostapd 937 * fixed couple of bugs in processing WPA deauthentication (freed data 938 was used) 939 940 2004-05-31 - v0.2.2 941 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM) 942 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix 943 cases where STAs dropped multicast frames as replay attacks 944 * added support for copying RADIUS Attribute 'Class' from 945 authentication messages into accounting messages 946 * send canned EAP failure if RADIUS server sends Access-Reject without 947 EAP message (previously, Supplicant was not notified in this case) 948 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do 949 not start EAPOL state machines if the STA selected to use WPA-PSK) 950 951 2004-05-06 - v0.2.1 952 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality 953 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA 954 (i.e., IEEE 802.11i/D3.0) 955 - supports WPA-only, RSN-only, and mixed WPA/RSN mode 956 - both WPA-PSK and WPA-RADIUS/EAP are supported 957 - PMKSA caching and pre-authentication 958 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase, 959 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey, 960 rsn_preauth, rsn_preauth_interfaces 961 * fixed interim accounting to remove any pending accounting messages 962 to the STA before sending a new one 963 964 2004-02-15 - v0.2.0 965 * added support for Acct-Interim-Interval: 966 - draft-ietf-radius-acct-interim-01.txt 967 - use Acct-Interim-Interval attribute from Access-Accept if local 968 'radius_acct_interim_interval' is not set 969 - allow different update intervals for each STA 970 * fixed event loop to call signal handlers only after returning from 971 the real signal handler 972 * reset sta->timeout_next after successful association to make sure 973 that the previously registered inactivity timer will not remove the 974 STA immediately (e.g., if STA deauthenticates and re-associates 975 before the timer is triggered). 976 * added new hostapd.conf variable, nas_identifier, that can be used to 977 add an optional RADIUS Attribute, NAS-Identifier, into authentication 978 and accounting messages 979 * added support for Accounting-On and Accounting-Off messages 980 * fixed accounting session handling to send Accounting-Start only once 981 per session and not to send Accounting-Stop if the session was not 982 initialized properly 983 * fixed Accounting-Stop statistics in cases where the message was 984 previously sent after the kernel entry for the STA (and/or IEEE 985 802.1X data) was removed 986 987 988 Note: 989 990 Older changes up to and including v0.1.0 are included in the ChangeLog 991 of the Host AP driver. 992
