v1.0 222 * Add channel selection support in hostapd. See hostapd.conf. 223 * Add support for IEEE 802.11v Time Advertisement mechanism with UTC 224 TSF offset. See hostapd.conf for config info. 225 * Delay STA entry removal until Deauth/Disassoc TX status in AP mode. 226 This allows the driver to use PS buffering of Deauthentication and 227 Disassociation frames when the STA is in power save sleep. Only 228 available with drivers that provide TX status events for Deauth/ 229 Disassoc frames (nl80211). 230 * Allow PMKSA caching to be disabled on the Authenticator. See 231 hostap.conf config parameter disable_pmksa_caching. 232 * atheros: Add support for IEEE 802.11w configuration. 233 * bsd: Add support for setting HT values in IFM_MMASK. 234 * Allow client isolation to be configured with ap_isolate. Client 235 isolation can be used to prevent low-level bridging of frames 236 between associated stations in the BSS. By default, this bridging 237 is allowed. 238 * Allow coexistance of HT BSSes with WEP/TKIP BSSes. 239 * Add require_ht config parameter, which can be used to configure 240 hostapd to reject association with any station that does not support 241 HT PHY. 242 * Add support for writing debug log to a file using "-f" option. Also 243 add relog CLI command to re-open the log file. 244 * Add bridge handling for WDS STA interfaces. By default they are 245 added to the configured bridge of the AP interface (if present), 246 but the user can also specify a separate bridge using cli command 247 wds_bridge. 248 * hostapd_cli: 249 - Add wds_bridge command for specifying bridge for WDS STA 250 interfaces. 251 - Add relog command for reopening log file. 252 - Send AP-STA-DISCONNECTED event when an AP disconnects a station 253 due to inactivity. 254 - Add wps_config ctrl_interface command for configuring AP.

It works in the same way as new AP settings received 257 from an ER. 258 - Many WPS/WPS ER commands - see WPS/WPS ER sections for details. 259 - Add command get version, that returns hostapd version string. 260 * WNM: Add BSS Transition Management Request for ESS Disassoc Imminent. 261 Use hostapd_cli ess_disassoc (STA addr) (URL) to send the 262 notification to the STA. 263 * Allow AP mode to disconnect STAs based on low ACK condition (when 264 the data connection is not working properly, e.g., due to the STA 265 going outside the range of the AP). Disabled by default, enable by 266 config option disassoc_low_ack. 267 * Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad 268 config file. 269 * WPS: 270 - Send AP Settings as a wrapped Credential attribute to ctrl_iface 271 in WPS-NEW-AP-SETTINGS. 272 - Dispatch more WPS events through hostapd ctrl_iface. 273 - Add mechanism for indicating non-standard WPS errors. 274 - Change concurrent radio AP to use only one WPS UPnP instance. 275 - Add wps_check_pin command for processing PIN from user input. 276 UIs can use this command to process a PIN entered by a user and to 277 validate the checksum digit (if present). 278 - Add hostap_cli get_config command to display current AP config. 279 - Add new hostapd_cli command, wps_ap_pin, to manage AP PIN at 280 runtime and support dynamic AP PIN management. 281 - Disable AP PIN after 10 consecutive failures. Slow down attacks 282 on failures up to 10. 283 - Allow AP to start in Enrollee mode without AP PIN for probing, 284 to be compatible with Windows 7. 285 - Add Config Error into WPS-FAIL events to provide more info 286 to the user on how to resolve the issue. 287 - When controlling multiple interfaces: 288 - apply WPS commands to all interfaces configured to use WPS 289 - apply WPS config changes to all interfaces that use WPS 290 - when an attack is detected on any interface, disable AP PIN on 291 all interfaces 292 * WPS ER: 293 - Show SetSelectedRegistrar events as ctrl_iface events. 294 - Add special AP Setup Locked mode to allow read only ER. 295 ap_setup_locked=2 can now be used to enable a special mode where 296 WPS ER can learn the current AP settings, but cannot change them. 297 * WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2) 298 - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool 299 for testing protocol extensibility. 300 - Add build option CONFIG_WPS_STRICT to allow disabling of WPS 301 workarounds. 302 - Add support for AuthorizedMACs attribute. 303 * TDLS: 304 - Allow TDLS use or TDLS channel switching in the BSS to be 305 prohibited in the BSS, using config params tdls_prohibit and 306 tdls_prohibit_chan_switch. 307 * EAP server: Add support for configuring fragment size (see 308 fragment_size in hostapd.conf). 309 * wlantest: Add a tool wlantest for IEEE802.11 protocol testing. 310 wlantest can be used to capture frames from a monitor interface 311 for realtime capturing or from pcap files for offline analysis. 312 * Interworking: Support added for 802.11u. Enable in .config with 313 CONFIG_INTERWORKING. See hostapd.conf for config parameters for 314 interworking. 315 * Android: Add build and runtime support for Android hostapd. 316 * Add a new debug message level for excessive information. Use 317 -ddd to enable. 318 * TLS: Add support for tls_disable_time_checks=1 in client mode. 319 * Internal TLS: 320 - Add support for TLS v1.1 (RFC 4346). Enable with build parameter 321 CONFIG_TLSV11. 322 - Add domainComponent parser for X.509 names 323 * Reorder some IEs to get closer to IEEE 802.11 standard. Move 324 WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames. 325 Move HT IEs to be later in (Re)Assoc Resp. 326 * Many bugfixes. 327 328 2010-04-18 - v0.7.2 329 * fix WPS internal Registrar use when an external Registrar is also 330 active 331 * bsd: Cleaned up driver wrapper and added various low-level 332 configuration options 333 * TNC: fixed issues with fragmentation 334 * EAP-TNC: add Flags field into fragment acknowledgement (needed to 335 interoperate with other implementations;

part configurable with CONFIG_NO_* build 403 options) 404 * use shared driver wrapper files with wpa_supplicant 405 * driver_nl80211: multiple updates to provide support for new Linux 406 nl80211/mac80211 functionality 407 * updated management frame protection to use IEEE Std 802.11w-2009 408 * fixed number of small WPS issues and added workarounds to 409 interoperate with common deployed broken implementations 410 * added some IEEE 802.11n co-existence rules to disable 40 MHz channels 411 or modify primary/secondary channels if needed based on neighboring 412 networks 413 * added support for NFC out-of-band mechanism with WPS 414 * added preliminary support for IEEE 802.11r RIC processing 415 416 2009-01-06 - v0.6.7 417 * added support for Wi-Fi Protected Setup (WPS) 418 (hostapd can now be configured to act as an integrated WPS Registrar 419 and provision credentials for WPS Enrollees using PIN and PBC 420 methods; external wireless Registrar can configure the AP, but 421 external WLAN Manager Registrars are not supported); WPS support can 422 be enabled by adding CONFIG_WPS=y into .config and setting the 423 runtime configuration variables in hostapd.conf (see WPS section in 424 the example configuration file); new hostapd_cli commands wps_pin and 425 wps_pbc are used to configure WPS negotiation; see README-WPS for 426 more details 427 * added IEEE 802.11n HT capability configuration (ht_capab) 428 * added support for generating Country IE based on nl80211 regulatory 429 information (added if ieee80211d=1 in configuration) 430 * fixed WEP authentication (both Open System and Shared Key) with 431 mac80211 432 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf) 433 * added support for using driver_test over UDP socket 434 * changed EAP-GPSK to use the IANA assigned EAP method type 51 435 * updated management frame protection to use IEEE 802.11w/D7.0 436 * fixed retransmission of EAP requests if no response is received 437 438 2008-11-23 - v0.6.6 439 * added a new configuration option, wpa_ptk_rekey, that can be used to 440 enforce frequent PTK rekeying, e.g., to mitigate some attacks against 441 TKIP deficiencies 442 * updated OpenSSL code for EAP-FAST to use an updated version of the 443 session ticket overriding API that was included into the upstream 444 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is 445 needed with that version anymore) 446 * changed channel flags configuration to read the information from 447 the driver (e.g., via driver_nl80211 when using mac80211) instead of 448 using hostapd as the source of the regulatory information (i.e., 449 information from CRDA is now used with mac80211); this allows 5 GHz 450 channels to be used with hostapd (if allowed in the current 451 regulatory domain) 452 * fixed EAP-TLS message processing for the last TLS message if it is 453 large enough to require fragmentation (e.g., if a large Session 454 Ticket data is included) 455 * fixed listen interval configuration for nl80211 drivers 456 457 2008-11-01 - v0.6.5 458 * added support for SHA-256 as X.509 certificate digest when using the 459 internal X.509/TLSv1 implementation 460 * fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer 461 identity lengths) 462 * fixed internal TLSv1 implementation for abbreviated handshake (used 463 by EAP-FAST server) 464 * added support for setting VLAN ID for STAs based on local MAC ACL 465 (accept_mac_file) as an alternative for RADIUS server-based 466 configuration 467 * updated management frame protection to use IEEE 802.11w/D6.0 468 (adds a new association ping to protect against unauthenticated 469 authenticate or (re)associate request frames dropping association) 470 * added support for using SHA256-based stronger key derivation for WPA2 471 (IEEE 802.11w) 472 * added new "driver wrapper" for RADIUS-only configuration 473 (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config) 474 * fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2) 475 is enabled in configuration 476 * changed EAP-FAST configuration to use separate fields for A-ID and 477 A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed 478 16-octet len binary value for better interoperability with some peer 479 implementations; eap_fast_a_id is now configured as a hex string 480 * driver_nl80211: Updated to match the current Linux mac80211 AP mode 481 configuration (wireless-testing.git and Linux kernel releases 482 starting from 2.6.29) 483 484 2008-08-10 - v0.6.4 485 * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2 486 Identity Request if identity is already known 487 * added support for EAP Sequences in EAP-FAST Phase 2 488 * added support for EAP-TNC (Trusted Network Connect) 489 (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST 490 changes needed to run two methods in sequence (IF-T) and the IF-IMV 491 and IF-TNCCS interfaces from TNCS) 492 * added support for optional cryptobinding with PEAPv0 493 * added fragmentation support for EAP-TNC 494 * added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled) 495 data 496 * added support for opportunistic key caching (OKC) 497 498 2008-02-22 - v0.6.3 499 * fixed Reassociation Response callback processing when using internal 500 MLME (driver_{hostap,nl80211,test}.c) 501 * updated FT support to use the latest draft, IEEE 802.11r/D9.0 502 * copy optional Proxy-State attributes into RADIUS response when acting 503 as a RADIUS authentication server 504 * fixed EAPOL state machine to handle a case in which no response is 505 received from the RADIUS authentication server; previous version 506 could have triggered a crash in some cases after a timeout 507 * fixed EAP-SIM/AKA realm processing to allow decorated usernames to 508 be used 509 * added a workaround for EAP-SIM/AKA peers that include incorrect null 510 termination in the username 511 * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER 512 attribute in notification messages only when using fast 513 reauthentication 514 * fixed EAP-SIM Start response processing for fast reauthentication 515 case 516 * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST} 517 phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method 518 519 2008-01-01 - v0.6.2 520 * fixed EAP-SIM and EAP-AKA message parser to validate attribute 521 lengths properly to avoid potential crash caused by invalid messages 522 * added data structure for storing allocated buffers (struct wpabuf); 523 this does not affect hostapd usage, but many of the APIs changed 524 and various interfaces (e.g., EAP) is not compatible with old 525 versions 526 * added support for protecting EAP-AKA/Identity messages with 527 AT_CHECKCODE (optional feature in RFC 4187) 528 * added support for protected result indication with AT_RESULT_IND for 529 EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1) 530 * added support for configuring EAP-TTLS phase 2 non-EAP methods in 531 EAP server configuration; previously all four were enabled for every 532 phase 2 user, now all four are disabled by default and need to be 533 enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP, 534 TTLS-MSCHAPV2 535 * removed old debug printing mechanism and the related 'debug' 536 parameter in the configuration file; debug verbosity is now set with 537 -d (or -dd) command line arguments 538 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt); 539 only shared key/password authentication is supported in this version 540 541 2007-11-24 - v0.6.1 542 * added experimental, integrated TLSv1 server implementation with the 543 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by 544 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in 545 .config); this can be useful, e.g., if the target system does not 546 have a suitable TLS library and a minimal code size is required 547 * added support for EAP-FAST server method to the integrated EAP 548 server 549 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 550 draft (draft-ietf-emu-eap-gpsk-07.txt) 551 * added a new configuration parameter, rsn_pairwise, to allow different 552 pairwise cipher suites to be enabled for WPA and RSN/WPA2 553 (note: if wpa_pairwise differs from rsn_pairwise, the driver will 554 either need to support this or will have to use the WPA/RSN IEs from 555 hostapd; currently, the included madwifi and bsd driver interfaces do 556 not have support for this) 557 * updated FT support to use the latest draft, IEEE 802.11r/D8.0 558 559 2007-05-28 - v0.6.0 560 * added experimental IEEE 802.11r/D6.0 support 561 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48 562 * updated EAP-PSK to use the IANA-allocated EAP type 47 563 * fixed EAP-PSK bit ordering of the Flags field 564 * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs 565 by reading wpa_psk_file [Bug 181] 566 * fixed EAP-TTLS AVP parser processing for too short AVP lengths 567 * fixed IPv6 connection to RADIUS accounting server 568 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 569 draft (draft-ietf-emu-eap-gpsk-04.txt) 570 * hlr_auc_gw: read GSM triplet file into memory and rotate through the 571 entries instead of only using the same three triplets every time 572 (this does not work properly with tests using multiple clients, but 573 provides bit better triplet data for testing a single client; anyway, 574 if a better quality triplets are needed, GSM-Milenage should be used 575 instead of hardcoded triplet file) 576 * fixed EAP-MSCHAPv2 server to use a space between S and M parameters 577 in Success Request [Bug 203] 578 * added support for sending EAP-AKA Notifications in error cases 579 * updated to use IEEE 802.11w/D2.0 for management frame protection 580 (still experimental) 581 * RADIUS server: added support for processing duplicate messages 582 (retransmissions from RADIUS client) by replying with the previous 583 reply 584 585 2006-11-24 - v0.5.6 586 * added support for configuring and controlling multiple BSSes per 587 radio interface (bss=<ifname> in hostapd.conf); this is only 588 available with Devicescape and test driver interfaces 589 * fixed PMKSA cache update in the end of successful RSN 590 pre-authentication 591 * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID 592 for each STA based on RADIUS Access-Accept attributes); this requires 593 VLAN support from the kernel driver/802.11 stack and this is 594 currently only available with Devicescape and test driver interfaces 595 * driver_madwifi: fixed configuration of unencrypted modes (plaintext 596 and IEEE 802.1X without WEP) 597 * removed STAKey handshake since PeerKey handshake has replaced it in 598 IEEE 802.11ma and there are no known deployments of STAKey 599 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 600 draft (draft-ietf-emu-eap-gpsk-01.txt) 601 * added preliminary implementation of IEEE 802.11w/D1.0 (management 602 frame protection) 603 (Note: this requires driver support to work properly.) 604 (Note2: IEEE 802.11w is an unapproved draft and subject to change.) 605 * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM) 606 * hlr_auc_gw: added support for reading per-IMSI Milenage keys and 607 parameters from a text file to make it possible to implement proper 608 GSM/UMTS authentication server for multiple SIM/USIM cards using 609 EAP-SIM/EAP-AKA 610 * fixed session timeout processing with drivers that do not use 611 ieee802_11.c (e.g., madwifi) 612 613 2006-08-27 - v0.5.5 614 * added 'hostapd_cli new_sta <addr>' command for adding a new STA into 615 hostapd (e.g., to initialize wired network authentication based on an 616 external signal) 617 * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when 618 using WPA2 even if PMKSA caching is not used 619 * added -P<pid file> argument for hostapd to write the current process 620 id into a file 621 * added support for RADIUS Authentication Server MIB (RFC 2619) 622 623 2006-06-20 - v0.5.4 624 * fixed nt_password_hash build [Bug 144] 625 * added PeerKey handshake implementation for IEEE 802.11e 626 direct link setup (DLS) to replace STAKey handshake 627 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK, 628 draft-clancy-emu-eap-shared-secret-00.txt) 629 * fixed a segmentation fault when RSN pre-authentication was completed 630 successfully [Bug 152] 631 632 2006-04-27 - v0.5.3 633 * do not build nt_password_hash and hlr_auc_gw by default to avoid 634 requiring a TLS library for a successful build; these programs can be 635 build with 'make nt_password_hash' and 'make hlr_auc_gw' 636 * added a new configuration option, eapol_version, that can be used to 637 set EAPOL version to 1 (default is 2) to work around broken client 638 implementations that drop EAPOL frames which use version number 2 639 [Bug 89] 640 * added support for EAP-SAKE (no EAP method number allocated yet, so 641 this is using the same experimental type 255 as EAP-PSK) 642 * fixed EAP-MSCHAPv2 message length validation 643 644 2006-03-19 - v0.5.2 645 * fixed stdarg use in hostapd_logger(): if both stdout and syslog 646 logging was enabled, hostapd could trigger a segmentation fault in 647 vsyslog on some CPU -- C library combinations 648 * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external 649 program to make it easier to use for implementing real SS7 gateway; 650 eap_sim_db is not anymore used as a file name for GSM authentication 651 triplets; instead, it is path to UNIX domain socket that will be used 652 to communicate with the external gateway program (e.g., hlr_auc_gw) 653 * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses 654 local information (GSM authentication triplets from a text file and 655 hardcoded AKA authentication data); this can be used to test EAP-SIM 656 and EAP-AKA 657 * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw 658 to make it possible to test EAP-AKA with real USIM cards (this is 659 disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw 660 to enable this) 661 * driver_madwifi: added support for getting station RSN IE from 662 madwifi-ng svn r1453 and newer; this fixes RSN that was apparently 663 broken with earlier change (r1357) in the driver 664 * changed EAP method registration to use a dynamic list of methods 665 instead of a static list generated at build time 666 * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE) 667 [Bug 125] 668 * added ap_max_inactivity configuration parameter 669 670 2006-01-29 - v0.5.1 671 * driver_test: added better support for multiple APs and STAs by using 672 a directory with sockets that include MAC address for each device in 673 the name (test_socket=DIR:/tmp/test) 674 * added support for EAP expanded type (vendor specific EAP methods) 675 676 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases) 677 * added experimental STAKey handshake implementation for IEEE 802.11e 678 direct link setup (DLS); note: this is disabled by default in both 679 build and runtime configuration (can be enabled with CONFIG_STAKEY=y 680 and stakey=1) 681 * added support for EAP methods to use callbacks to external programs 682 by buffering a pending request and processing it after the EAP method 683 is ready to continue 684 * improved EAP-SIM database interface to allow external request to GSM 685 HLR/AuC without blocking hostapd process 686 * added support for using EAP-SIM pseudonyms and fast re-authentication 687 * added support for EAP-AKA in the integrated EAP authenticator 688 * added support for matching EAP identity prefixes (e.g., "1"*) in EAP 689 user database to allow EAP-SIM/AKA selection without extra roundtrip 690 for EAP-Nak negotiation 691 * added support for storing EAP user password as NtPasswordHash instead 692 of plaintext password when using MSCHAP or MSCHAPv2 for 693 authentication (hash:<16-octet hex value>); added nt_password_hash 694 tool for hashing password to generate NtPasswordHash 695 696 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases) 697 * driver_wired: fixed EAPOL sending to optionally use PAE group address 698 as the destination instead of supplicant MAC address; this is 699 disabled by default, but should be enabled with use_pae_group_addr=1 700 in configuration file if the wired interface is used by only one 701 device at the time (common switch configuration) 702 * driver_madwifi: configure driver to use TKIP countermeasures in order 703 to get correct behavior (IEEE 802.11 association failing; previously, 704 association succeeded, but hostpad forced disassociation immediately) 705 * driver_madwifi: added support for madwifi-ng 706 707 2005-10-27 - v0.4.6 708 * added support for replacing user identity from EAP with RADIUS 709 User-Name attribute from Access-Accept message, if that is included, 710 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get 711 tunneled identity into accounting messages when the RADIUS server 712 does not support better way of doing this with Class attribute) 713 * driver_madwifi: fixed EAPOL packet receive for configuration where 714 ath# is part of a bridge interface 715 * added a configuration file and log analyzer script for logwatch 716 * fixed EAPOL state machine step function to process all state 717 transitions before processing new events; this resolves a race 718 condition in which EAPOL-Start message could trigger hostapd to send 719 two EAP-Response/Identity frames to the authentication server 720 721 2005-09-25 - v0.4.5 722 * added client CA list to the TLS certificate request in order to make 723 it easier for the client to select which certificate to use 724 * added experimental support for EAP-PSK 725 * added support for WE-19 (hostap, madwifi) 726 727 2005-08-21 - v0.4.4 728 * fixed build without CONFIG_RSN_PREAUTH 729 * fixed FreeBSD build 730 731 2005-06-26 - v0.4.3 732 * fixed PMKSA caching to copy User-Name and Class attributes so that 733 RADIUS accounting gets correct information 734 * start RADIUS accounting only after successful completion of WPA 735 4-Way Handshake if WPA-PSK is used 736 * fixed PMKSA caching for the case where STA (re)associates without 737 first disassociating 738 739 2005-06-12 - v0.4.2 740 * EAP-PAX is now registered as EAP type 46 741 * fixed EAP-PAX MAC calculation 742 * fixed EAP-PAX CK and ICK key derivation 743 * renamed eap_authenticator configuration variable to eap_server to 744 better match with RFC 3748 (EAP) terminology 745 * driver_test: added support for testing hostapd with wpa_supplicant 746 by using test driver interface without any kernel drivers or network 747 cards 748 749 2005-05-22 - v0.4.1 750 * fixed RADIUS server initialization when only auth or acct server 751 is configured and the other one is left empty 752 * driver_madwifi: added support for RADIUS accounting 753 * driver_madwifi: added preliminary support for compiling against 'BSD' 754 branch of madwifi CVS tree 755 * driver_madwifi: fixed pairwise key removal to allow WPA reauth 756 without disassociation 757 * added support for reading additional certificates from PKCS#12 files 758 and adding them to the certificate chain 759 * fixed RADIUS Class attribute processing to only use Access-Accept 760 packets to update Class; previously, other RADIUS authentication 761 packets could have cleared Class attribute 762 * added support for more than one Class attribute in RADIUS packets 763 * added support for verifying certificate revocation list (CRL) when 764 using integrated EAP authenticator for EAP-TLS; new hostapd.conf 765 options 'check_crl'; CRL must be included in the ca_cert file for now 766 767 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases) 768 * added support for including network information into 769 EAP-Request/Identity message (ASCII-0 (nul) in eap_message) 770 (e.g., to implement draft-adrange-eap-network-discovery-07.txt) 771 * fixed a bug which caused some RSN pre-authentication cases to use 772 freed memory and potentially crash hostapd 773 * fixed private key loading for cases where passphrase is not set 774 * added support for sending TLS alerts and aborting authentication 775 when receiving a TLS alert 776 * fixed WPA2 to add PMKSA cache entry when using integrated EAP 777 authenticator 778 * fixed PMKSA caching (EAP authentication was not skipped correctly 779 with the new state machine changes from IEEE 802.1X draft) 780 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr, 781 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs 782 to be added to .config to include IPv6 support); for RADIUS server, 783 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses 784 in RADIUS clients file can then use IPv6 format 785 * added experimental support for EAP-PAX 786 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with 787 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch]) 788 789 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases) 790 791 2005-01-23 - v0.3.5 792 * added support for configuring a forced PEAP version based on the 793 Phase 1 identity 794 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV 795 to terminate authentication 796 * fixed EAP identifier duplicate processing with the new IEEE 802.1X 797 draft 798 * clear accounting data in the driver when starting a new accounting 799 session 800 * driver_madwifi: filter wireless events based on ifindex to allow more 801 than one network interface to be used 802 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt 803 setting if the packet does not pass MIC verification (e.g., due to 804 incorrect PSK); previously, message 1/4 was not tried again if an 805 invalid message 2/4 was received 806 * fixed reconfiguration of RADIUS client retransmission timer when 807 adding a new message to the pending list; previously, timer was not 808 updated at this point and if there was a pending message with long 809 time for the next retry, the new message needed to wait that long for 810 its first retry, too 811 812 2005-01-09 - v0.3.4 813 * added support for configuring multiple allowed EAP types for Phase 2 814 authentication (EAP-PEAP, EAP-TTLS) 815 * fixed EAPOL-Start processing to trigger WPA reauthentication 816 (previously, only EAPOL authentication was done) 817 818 2005-01-02 - v0.3.3 819 * added support for EAP-PEAP in the integrated EAP authenticator 820 * added support for EAP-GTC in the integrated EAP authenticator 821 * added support for configuring list of EAP methods for Phase 1 so that 822 the integrated EAP authenticator can, e.g., use the wildcard entry 823 for EAP-TLS and EAP-PEAP 824 * added support for EAP-TTLS in the integrated EAP authenticator 825 * added support for EAP-SIM in the integrated EAP authenticator 826 * added support for using hostapd as a RADIUS authentication server 827 with the integrated EAP authenticator taking care of EAP 828 authentication (new hostapd.conf options: radius_server_clients and 829 radius_server_auth_port); this is not included in default build; use 830 CONFIG_RADIUS_SERVER=y in .config to include 831 832 2004-12-19 - v0.3.2 833 * removed 'daemonize' configuration file option since it has not really 834 been used at all for more than year 835 * driver_madwifi: fixed group key setup and added get_ssid method 836 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator 837 838 2004-12-12 - v0.3.1 839 * added support for integrated EAP-TLS authentication (new hostapd.conf 840 variables: ca_cert, server_cert, private_key, private_key_passwd); 841 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without 842 external RADIUS server 843 * added support for reading PKCS#12 (PFX) files (as a replacement for 844 PEM/DER) to get certificate and private key (CONFIG_PKCS12) 845 846 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases) 847 * added support for Acct-{Input,Output}-Gigawords 848 * added support for Event-Timestamp (in RADIUS Accounting-Requests) 849 * added support for RADIUS Authentication Client MIB (RFC2618) 850 * added support for RADIUS Accounting Client MIB (RFC2620) 851 * made EAP re-authentication period configurable (eap_reauth_period) 852 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication 853 * fixed EAPOL state machine to stop if STA is removed during 854 eapol_sm_step(); this fixes at least one segfault triggering bug with 855 IEEE 802.11i pre-authentication 856 * added support for multiple WPA pre-shared keys (e.g., one for each 857 client MAC address or keys shared by a group of clients); 858 new hostapd.conf field wpa_psk_file for setting path to a text file 859 containing PSKs, see hostapd.wpa_psk for an example 860 * added support for multiple driver interfaces to allow hostapd to be 861 used with other drivers 862 * added wired authenticator driver interface (driver=wired in 863 hostapd.conf, see wired.conf for example configuration) 864 * added madwifi driver interface (driver=madwifi in hostapd.conf, see 865 madwifi.conf for example configuration; Note: include files from 866 madwifi project is needed for building and a configuration file, 867 .config, needs to be created in hostapd directory with 868 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd 869 build) 870 * fixed an alignment issue that could cause SHA-1 to fail on some 871 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit 872 align variables) 873 * fixed RADIUS reconnection after an error in sending interim 874 accounting packets 875 * added hostapd control interface for external programs and an example 876 CLI, hostapd_cli (like wpa_cli for wpa_supplicant) 877 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib', 878 'hostapd_cli sta <addr>') 879 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11) 880 * added support for strict GTK rekeying (wpa_strict_rekey in 881 hostapd.conf) 882 * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178 883 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to 884 IEEE 802.11F-2003) 885 * added Prism54 driver interface (driver=prism54 in hostapd.conf; 886 note: .config needs to be created in hostapd directory with 887 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd 888 build) 889 * dual-licensed hostapd (GPLv2 and BSD licenses) 890 * fixed RADIUS accounting to generate a new session id for cases where 891 a station reassociates without first being complete deauthenticated 892 * fixed STA disassociation handler to mark next timeout state to 893 deauthenticate the station, i.e., skip long wait for inactivity poll 894 and extra disassociation, if the STA disassociates without 895 deauthenticating 896 * added integrated EAP authenticator that can be used instead of 897 external RADIUS authentication server; currently, only EAP-MD5 is 898 supported, so this cannot yet be used for key distribution; the EAP 899 method interface is generic, though, so adding new EAP methods should 900 be straightforward; new hostapd.conf variables: 'eap_authenticator' 901 and 'eap_user_file'; this obsoletes "minimal authentication server" 902 ('minimal_eap' in hostapd.conf) which is now removed 903 * added support for FreeBSD and driver interface for the BSD net80211 904 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in 905 .config); please note that some of the required kernel mods have not 906 yet been committed 907 908 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases) 909 * fixed some accounting cases where Accounting-Start was sent when 910 IEEE 802.1X port was being deauthorized 911 912 2004-06-20 - v0.2.3 913 * modified RADIUS client to re-connect the socket in case of certain 914 error codes that are generated when a network interface state is 915 changes (e.g., when IP address changes or the interface is set UP) 916 * fixed couple of cases where EAPOL state for a station was freed 917 twice causing a segfault for hostapd 918 * fixed couple of bugs in processing WPA deauthentication (freed data 919 was used) 920 921 2004-05-31 - v0.2.2 922 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM) 923 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix 924 cases where STAs dropped multicast frames as replay attacks 925 * added support for copying RADIUS Attribute 'Class' from 926 authentication messages into accounting messages 927 * send canned EAP failure if RADIUS server sends Access-Reject without 928 EAP message (previously, Supplicant was not notified in this case) 929 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do 930 not start EAPOL state machines if the STA selected to use WPA-PSK) 931 932 2004-05-06 - v0.2.1 933 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality 934 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA 935 (i.e., IEEE 802.11i/D3.0) 936 - supports WPA-only, RSN-only, and mixed WPA/RSN mode 937 - both WPA-PSK and WPA-RADIUS/EAP are supported 938 - PMKSA caching and pre-authentication 939 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase, 940 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey, 941 rsn_preauth, rsn_preauth_interfaces 942 * fixed interim accounting to remove any pending accounting messages 943 to the STA before sending a new one 944 945 2004-02-15 - v0.2.0 946 * added support for Acct-Interim-Interval: 947 - draft-ietf-radius-acct-interim-01.txt 948 - use Acct-Interim-Interval attribute from Access-Accept if local 949 'radius_acct_interim_interval' is not set 950 - allow different update intervals for each STA 951 * fixed event loop to call signal handlers only after returning from 952 the real signal handler 953 * reset sta->timeout_next after successful association to make sure 954 that the previously registered inactivity timer will not remove the 955 STA immediately (e.g., if STA deauthenticates and re-associates 956 before the timer is triggered). 957 * added new hostapd.conf variable, nas_identifier, that can be used to 958 add an optional RADIUS Attribute, NAS-Identifier, into authentication 959 and accounting messages 960 * added support for Accounting-On and Accounting-Off messages 961 * fixed accounting session handling to send Accounting-Start only once 962 per session and not to send Accounting-Stop if the session was not 963 initialized properly 964 * fixed Accounting-Stop statistics in cases where the message was 965 previously sent after the kernel entry for the STA (and/or IEEE 966 802.1X data) was removed 967 968 969 Note: 970 971 Older changes up to and including v0.1.0 are included in the ChangeLog 972 of the Host AP driver. 973
