Disabled by default, enable by 256 config option disassoc_low_ack. 257 * nl80211: 258 - Support GTK rekey offload. 259 - Support PMKSA candidate events. This adds support for RSN 260 pre-authentication with nl80211 interface and drivers that handle 261 roaming internally. 262 * dbus: 263 - Add a DBus signal for EAP SM requests, emitted on the Interface 264 object. 265 - Export max scan ssids supported by the driver as MaxScanSSID. 266 - Add signal Certification for information about server certification. 267 - Add BSSExpireAge and BSSExpireCount interface properties and 268 support set/get, which allows for setting BSS cache expiration age 269 and expiration scan count. 270 - Add ConfigFile to AddInterface properties. 271 - Add Interface.Country property and support to get/set the value. 272 - Add DBus property CurrentAuthMode. 273 - P2P DBus API added. 274 - Emit property changed events (for property BSSs) when adding/ 275 removing BSSs. 276 - Treat '' in SSIDs of Interface.Scan as a request for broadcast 277 scan, instead of ignoring it. 278 - Add DBus getter/setter for FastReauth. 279 - Raise PropertiesChanged on org.freedesktop.DBus.Properties. 280 * wpa_cli: 281 - Send AP-STA-DISCONNECTED event when an AP disconnects a station 282 due to inactivity. 283 - Make second argument to set command optional. This can be used to 284 indicate a zero length value. 285 - Add signal_poll command. 286 - Add bss_expire_age and bss_expire_count commands to set/get BSS 287 cache expiration age and expiration scan count. 288 - Add ability to set scan interval (the time in seconds wpa_s waits 289 before requesting a new scan after failing to find a suitable 290 network in scan results) using scan_interval command. 291 - Add event CTRL-EVENT-ASSOC-REJECT for association rejected. 292 - Add command get version, that returns wpa_supplicant version string. 293 - Add command sta_autoconnect for disabling automatic reconnection 294 on receiving disconnection event. 295 - Setting bssid parameter to an empty string "" or any can now be 296 used to clear the bssid_set flag in a network block, i.e., to remove 297 bssid filtering. 298 - Add tdls_testing command to add a special testing feature for 299 changing TDLS behavior. Build param CONFIG_TDLS_TESTING must be 300 enabled as well. 301 - For interworking, add wpa_cli commands interworking_select, 302 interworking_connect, anqp_get, fetch_anqp, and stop_fetch_anqp. 303 - Many P2P commands were added. See README-P2P. 304 - Many WPS/WPS ER commands - see WPS/WPS ER sections for details. 305 - Allow set command to change global config parameters. 306 - Add log_level command, which can be used to display the current 307 debugging level and to change the log level during run time. 308 - Add note command, which can be used to insert notes to the debug 309 log. 310 - Add internal line edit implementation. CONFIG_WPA_CLI_EDIT=y 311 can now be used to build wpa_cli with internal implementation of 312 line editing and history support. This can be used as a replacement 313 for CONFIG_READLINE=y. 314 * AP mode: Add max_num_sta config option, which can be used to limit 315 the number of stations allowed to connect to the AP. 316 * Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad 317 config file. 318 * wext: Increase scan timeout from 5 to 10 seconds. 319 * Add blacklist command, allowing an external program to 320 manage the BSS blacklist and display its current contents. 321 * WPS: 322 - Add wpa_cli wps_pin get command for generating random PINs. This can 323 be used in a UI to generate a PIN without starting WPS (or P2P) 324 operation. 325 - Set RF bands based on driver capabilities, instead of hardcoding 326 them. 327 - Add mechanism for indicating non-standard WPS errors. 328 - Add CONFIG_WPS_REG_DISABLE_OPEN=y option to disable open networks 329 by default. 330 - Add wps_ap_pin cli command for wpa_supplicant AP mode. 331 - Add wps_check_pin cli command for processing PIN from user input. 332 UIs can use this command to process a PIN entered by a user and to 333 validate the checksum digit (if present). 334 - Cancel WPS operation on PBC session overlap detection. 335 - New wps_cancel command in wpa_cli will cancel a pending WPS 336 operation. 337 - wpa_cli action: Add WPS_EVENT_SUCCESS and WPS_EVENT_FAIL handlers. 338 - Trigger WPS config update on Manufacturer, Model Name, Model 339 Number, and Serial Number changes. 340 - Fragment size is now configurable for EAP-WSC peer.

Slow down attacks on 343 failures up to 10. 344 - Allow AP to start in Enrollee mode without AP PIN for probing, to 345 be compatible with Windows 7. 346 - Add Config Error into WPS-FAIL events to provide more info to the 347 user on how to resolve the issue. 348 - Label and Display config methods are not allowed to be enabled 349 at the same time, since it is unclear which PIN to use if both 350 methods are advertised. 351 - When controlling multiple interfaces: 352 - apply WPS commands to all interfaces configured to use WPS 353 - apply WPS config changes to all interfaces that use WPS 354 - when an attack is detected on any interface, disable AP PIN on 355 all interfaces 356 * WPS ER: 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 - Show SetSelectedRegistrar events as ctrl_iface events 361 - Add wps_er_set_config to enroll a network based on a local 362 network configuration block instead of having to (re-)learn the 363 current AP settings with wps_er_learn. 364 - Allow AP filtering based on IP address, add ctrl_iface event for 365 learned AP settings, add wps_er_config command to configure an AP. 366 * WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2) 367 - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool 368 for testing protocol extensibility. 369 - Add build option CONFIG_WPS_STRICT to allow disabling of WPS 370 workarounds. 371 - Add support for AuthorizedMACs attribute. 372 * TDLS: 373 - Propogate TDLS related nl80211 capability flags from kernel and 374 add them as driver capability flags. If the driver doesn't support 375 capabilities, assume TDLS is supported internally. When TDLS is 376 explicitly not supported, disable all user facing TDLS operations. 377 - Allow TDLS to be disabled at runtime (mostly for testing). 378 Use set tdls_disabled. 379 - Honor AP TDLS settings that prohibit/allow TDLS. 380 - Add a special testing feature for changing TDLS behavior. Use 381 CONFIG_TDLS_TESTING build param to enable. Configure at runtime 382 with tdls_testing cli command. 383 - Add support for TDLS 802.11z. 384 * wlantest: Add a tool wlantest for IEEE802.11 protocol testing. 385 wlantest can be used to capture frames from a monitor interface 386 for realtime capturing or from pcap files for offline analysis. 387 * Interworking: Support added for 802.11u. Enable in .config with 388 CONFIG_INTERWORKING. See wpa_supplicant.conf for config parameters 389 for interworking. wpa_cli commands added to support this are 390 interworking_select, interworking_connect, anqp_get, fetch_anqp, 391 and stop_fetch_anqp. 392 * Android: Add build and runtime support for Android wpa_supplicant. 393 * bgscan learn: Add new bgscan that learns BSS information based on 394 previous scans, and uses that information to dynamically generate 395 the list of channels for background scans. 396 * Add a new debug message level for excessive information. Use 397 -ddd to enable. 398 * TLS: Add support for tls_disable_time_checks=1 in client mode. 399 * Internal TLS: 400 - Add support for TLS v1.1 (RFC 4346). Enable with build parameter 401 CONFIG_TLSV11. 402 - Add domainComponent parser for X.509 names. 403 * Linux: Add RFKill support by adding an interface state "disabled". 404 * Reorder some IEs to get closer to IEEE 802.11 standard. Move 405 WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames. 406 Move HT IEs to be later in (Re)Assoc Resp. 407 * Solaris: Add support for wired 802.1X client. 408 * Wi-Fi Direct support. See README-P2P for more information. 409 * Many bugfixes. 410 411 2010-04-18 - v0.7.2 412 * nl80211: fixed number of issues with roaming 413 * avoid unnecessary roaming if multiple APs with similar signal 414 strength are present in scan results 415 * add TLS client events and server probing to ease design of 416 automatic detection of EAP parameters 417 * add option for server certificate matching (SHA256 hash of the 418 certificate) instead of trusted CA certificate configuration 419 * bsd: Cleaned up driver wrapper and added various low-level 420 configuration options 421 * wpa_gui-qt4: do not show too frequent WPS AP available events as 422 tray messages 423 * TNC: fixed issues with fragmentation 424 * EAP-TNC: add Flags field into fragment acknowledgement (needed to 425 interoperate with other implementations; may potentially breaks 426 compatibility with older wpa_supplicant/hostapd versions) 427 * wpa_cli: added option for using a separate process to receive event 428 messages to reduce latency in showing these 429 (CFLAGS += -DCONFIG_WPA_CLI_FORK=y in .config to enable this) 430 * maximum BSS table size can now be configured (bss_max_count) 431 * BSSes to be included in the BSS table can be filtered based on 432 configured SSIDs to save memory (filter_ssids) 433 * fix number of issues with IEEE 802.11r/FT; this version is not 434 backwards compatible with old versions 435 * nl80211: add support for IEEE 802.11r/FT protocol (both over-the-air 436 and over-the-DS) 437 * add freq_list network configuration parameter to allow the AP 438 selection to filter out entries based on the operating channel 439 * add signal strength change events for bgscan; this allows more 440 dynamic changes to background scanning interval based on changes in 441 the signal strength with the current AP; this improves roaming within 442 ESS quite a bit, e.g., with bgscan="simple:30:-45:300" in the network 443 configuration block to request background scans less frequently when 444 signal strength remains good and to automatically trigger background 445 scans whenever signal strength drops noticeably 446 (this is currently only available with nl80211) 447 * add BSSID and reason code (if available) to disconnect event messages 448 * wpa_gui-qt4: more complete support for translating the GUI with 449 linguist and add German translation 450 * fix DH padding with internal crypto code (mainly, for WPS) 451 * do not trigger initial scan automatically anymore if there are no 452 enabled networks 453 454 2010-01-16 - v0.7.1 455 * cleaned up driver wrapper API (struct wpa_driver_ops); the new API 456 is not fully backwards compatible, so out-of-tree driver wrappers 457 will need modifications 458 * cleaned up various module interfaces 459 * merge hostapd and wpa_supplicant developers' documentation into a 460 single document 461 * nl80211: use explicit deauthentication to clear cfg80211 state to 462 avoid issues when roaming between APs 463 * dbus: major design changes in the new D-Bus API 464 (fi.w1.wpa_supplicant1) 465 * nl80211: added support for IBSS networks 466 * added internal debugging mechanism with backtrace support and memory 467 allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y) 468 * added WPS ER unsubscription command to more cleanly unregister from 469 receiving UPnP events when ER is terminated 470 * cleaned up AP mode operations to avoid need for virtual driver_ops 471 wrapper 472 * added BSS table to maintain more complete scan result information 473 over multiple scans (that may include only partial results) 474 * wpa_gui-qt4: update Peers dialog information more dynamically while 475 the dialog is kept open 476 * fixed PKCS#12 use with OpenSSL 1.0.0 477 * driver_wext: Added cfg80211-specific optimization to avoid some 478 unnecessary scans and to speed up association 479 480 2009-11-21 - v0.7.0 481 * increased wpa_cli ping interval to 5 seconds and made this 482 configurable with a new command line options (-G<seconds>) 483 * fixed scan buffer processing with WEXT to handle up to 65535 484 byte result buffer (previously, limited to 32768 bytes) 485 * allow multiple driver wrappers to be specified on command line 486 (e.g., -Dnl80211,wext); the first one that is able to initialize the 487 interface will be used 488 * added support for multiple SSIDs per scan request to optimize 489 scan_ssid=1 operations in ap_scan=1 mode (i.e., search for hidden 490 SSIDs); this requires driver support and can currently be used only 491 with nl80211 492 * added support for WPS USBA out-of-band mechanism with USB Flash 493 Drives (UFD) (CONFIG_WPS_UFD=y) 494 * driver_ndis: add PAE group address to the multicast address list to 495 fix wired IEEE 802.1X authentication 496 * fixed IEEE 802.11r key derivation function to match with the standard 497 (note: this breaks interoperability with previous version) [Bug 303] 498 * added better support for drivers that allow separate authentication 499 and association commands (e.g., mac80211-based Linux drivers with 500 nl80211; SME in wpa_supplicant); this allows over-the-air FT protocol 501 to be used (IEEE 802.11r) 502 * fixed SHA-256 based key derivation function to match with the 503 standard when using CCMP (for IEEE 802.11r and IEEE 802.11w) 504 (note: this breaks interoperability with previous version) [Bug 307] 505 * use shared driver wrapper files with hostapd 506 * added AP mode functionality (CONFIG_AP=y) with mode=2 in the network 507 block; this can be used for open and WPA2-Personal networks 508 (optionally, with WPS); this links in parts of hostapd functionality 509 into wpa_supplicant 510 * wpa_gui-qt4: added new Peers dialog to show information about peers 511 (other devices, including APs and stations, etc. in the neighborhood) 512 * added support for WPS External Registrar functionality (configure APs 513 and enroll new devices); can be used with wpa_gui-qt4 Peers dialog 514 and wpa_cli commands wps_er_start, wps_er_stop, wps_er_pin, 515 wps_er_pbc, wps_er_learn 516 (this can also be used with a new 'none' driver wrapper if no 517 wireless device or IEEE 802.1X on wired is needed) 518 * driver_nl80211: multiple updates to provide support for new Linux 519 nl80211/mac80211 functionality 520 * updated management frame protection to use IEEE Std 802.11w-2009 521 * fixed number of small WPS issues and added workarounds to 522 interoperate with common deployed broken implementations 523 * added support for NFC out-of-band mechanism with WPS 524 * driver_ndis: fixed wired IEEE 802.1X authentication with PAE group 525 address frames 526 * added preliminary support for IEEE 802.11r RIC processing 527 * added support for specifying subset of enabled frequencies to scan 528 (scan_freq option in the network configuration block); this can speed 529 up scanning process considerably if it is known that only a small 530 subset of channels is actually used in the network (this is currently 531 supported only with -Dnl80211) 532 * added a workaround for race condition between receiving the 533 association event and the following EAPOL-Key 534 * added background scan and roaming infrastructure to allow 535 network-specific optimizations to be used to improve roaming within 536 an ESS (same SSID) 537 * added new DBus interface (fi.w1.wpa_supplicant1) 538 539 2009-01-06 - v0.6.7 540 * added support for Wi-Fi Protected Setup (WPS) 541 (wpa_supplicant can now be configured to act as a WPS Enrollee to 542 enroll credentials for a network using PIN and PBC methods; in 543 addition, wpa_supplicant can act as a wireless WPS Registrar to 544 configure an AP); WPS support can be enabled by adding CONFIG_WPS=y 545 into .config and setting the runtime configuration variables in 546 wpa_supplicant.conf (see WPS section in the example configuration 547 file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to 548 manage WPS negotiation; see README-WPS for more details 549 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf) 550 * added support for using driver_test over UDP socket 551 * fixed PEAPv0 Cryptobinding interoperability issue with Windows Server 552 2008 NPS; optional cryptobinding is now enabled (again) by default 553 * fixed PSK editing in wpa_gui 554 * changed EAP-GPSK to use the IANA assigned EAP method type 51 555 * added a Windows installer that includes WinPcap and all the needed 556 DLLs; in addition, it set up the registry automatically so that user 557 will only need start wpa_gui to get prompted to start the wpasvc 558 servide and add a new interface if needed through wpa_gui dialog 559 * updated management frame protection to use IEEE 802.11w/D7.0 560 561 2008-11-23 - v0.6.6 562 * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA 563 (can be used to simulate test SIM/USIM card with a known private key; 564 enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config 565 and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration) 566 * added a new network configuration option, wpa_ptk_rekey, that can be 567 used to enforce frequent PTK rekeying, e.g., to mitigate some attacks 568 against TKIP deficiencies 569 * added an optional mitigation mechanism for certain attacks against 570 TKIP by delaying Michael MIC error reports by a random amount of time 571 between 0 and 60 seconds; this can be enabled with a build option 572 CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config 573 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits, 574 not bytes 575 * updated OpenSSL code for EAP-FAST to use an updated version of the 576 session ticket overriding API that was included into the upstream 577 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is 578 needed with that version anymore) 579 * updated userspace MLME instructions to match with the current Linux 580 mac80211 implementation; please also note that this can only be used 581 with driver_nl80211.c (the old code from driver_wext.c was removed) 582 * added support (Linux only) for RoboSwitch chipsets (often found in 583 consumer grade routers); driver interface 'roboswitch' 584 * fixed canceling of PMKSA caching when using drivers that generate 585 RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know 586 about 587 588 2008-11-01 - v0.6.5 589 * added support for SHA-256 as X.509 certificate digest when using the 590 internal X.509/TLSv1 implementation 591 * updated management frame protection to use IEEE 802.11w/D6.0 592 * added support for using SHA256-based stronger key derivation for WPA2 593 (IEEE 802.11w) 594 * fixed FT (IEEE 802.11r) authentication after a failed association to 595 use correct FTIE 596 * added support for configuring Phase 2 (inner/tunneled) authentication 597 method with wpa_gui-qt4 598 599 2008-08-10 - v0.6.4 600 * added support for EAP Sequences in EAP-FAST Phase 2 601 * added support for using TNC with EAP-FAST 602 * added driver_ps3 for the PS3 Linux wireless driver 603 * added support for optional cryptobinding with PEAPv0 604 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to 605 allow fallback to full handshake if server rejects PAC-Opaque 606 * added fragmentation support for EAP-TNC 607 * added support for parsing PKCS #8 formatted private keys into the 608 internal TLS implementation (both PKCS #1 RSA key and PKCS #8 609 encapsulated RSA key can now be used) 610 * added option of using faster, but larger, routines in the internal 611 LibTomMath (for internal TLS implementation) to speed up DH and RSA 612 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y) 613 * fixed race condition between disassociation event and group key 614 handshake to avoid getting stuck in incorrect state [Bug 261] 615 * fixed opportunistic key caching (proactive_key_caching) 616 617 2008-02-22 - v0.6.3 618 * removed 'nai' and 'eappsk' network configuration variables that were 619 previously used for configuring user identity and key for EAP-PSK, 620 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the 621 replacement for 'nai' (if old configuration used a separate 622 'identity' value, that would now be configured as 623 'anonymous_identity'). 'password' field is now used as the 624 replacement for 'eappsk' (it can also be set using hexstring to 625 present random binary data) 626 * removed '-w' command line parameter (wait for interface to be added, 627 if needed); cleaner way of handling this functionality is to use an 628 external mechanism (e.g., hotplug scripts) that start wpa_supplicant 629 when an interface is added 630 * updated FT support to use the latest draft, IEEE 802.11r/D9.0 631 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for 632 indicating when new scan results become available 633 * added new ctrl_iface command, BSS, to allow scan results to be 634 fetched without hitting the message size limits (this command 635 can be used to iterate through the scan results one BSS at the time) 636 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION 637 attributes in EAP-SIM Start/Response when using fast reauthentication 638 * fixed EAPOL not to end up in infinite loop when processing dynamic 639 WEP keys with IEEE 802.1X 640 * fixed problems in getting NDIS events from WMI on Windows 2000 641 642 2008-01-01 - v0.6.2 643 * added support for Makefile builds to include debug-log-to-a-file 644 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line) 645 * fixed EAP-SIM and EAP-AKA message parser to validate attribute 646 lengths properly to avoid potential crash caused by invalid messages 647 * added data structure for storing allocated buffers (struct wpabuf); 648 this does not affect wpa_supplicant usage, but many of the APIs 649 changed and various interfaces (e.g., EAP) is not compatible with old 650 versions 651 * added support for protecting EAP-AKA/Identity messages with 652 AT_CHECKCODE (optional feature in RFC 4187) 653 * added support for protected result indication with AT_RESULT_IND for 654 EAP-SIM and EAP-AKA (phase1="result_ind=1") 655 * added driver_wext workaround for race condition between scanning and 656 association with drivers that take very long time to scan all 657 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now 658 using a longer hardcoded timeout for the scan if the driver supports 659 notifications for scan completion (SIOCGIWSCAN event); this helps, 660 e.g., in cases where wpa_supplicant and madwifi driver ended up in 661 loop where the driver did not even try to associate 662 * stop EAPOL timer tick when no timers are in use in order to reduce 663 power consumption (no need to wake up the process once per second) 664 [Bug 237] 665 * added support for privilege separation (run only minimal part of 666 wpa_supplicant functionality as root and rest as unprivileged, 667 non-root process); see 'Privilege separation' in README for details; 668 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y 669 in .config 670 * changed scan results data structure to include all information 671 elements to make it easier to support new IEs; old get_scan_result() 672 driver_ops is still supported for backwards compatibility (results 673 are converted internally to the new format), but all drivers should 674 start using the new get_scan_results2() to make them more likely to 675 work with new features 676 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4 677 application, i.e., it does not require Qt3Support anymore; Windows 678 binary of wpa_gui.exe is now from this directory and only requires 679 QtCore4.dll and QtGui4.dll libraries 680 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs 681 available as a separate package to make wpa_gui installation easier: 682 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip 683 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt); 684 only shared key/password authentication is supported in this version 685 686 2007-11-24 - v0.6.1 687 * added support for configuring password as NtPasswordHash 688 (16-byte MD4 hash of password) in hash:<32 hex digits> format 689 * added support for fallback from abbreviated TLS handshake to 690 full handshake when using EAP-FAST (e.g., due to an expired 691 PAC-Opaque) 692 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 693 draft (draft-ietf-emu-eap-gpsk-07.txt) 694 * added support for drivers that take care of RSN 4-way handshake 695 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and 696 WPA_ALG_PMK in set_key) 697 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in 698 .config); this version supports only ap_scan=2 mode and allow the 699 driver to take care of the 4-way handshake 700 * fixed a buffer overflow in parsing TSF from scan results when using 701 driver_wext.c with a driver that includes the TSF (e.g., iwl4965) 702 [Bug 232] 703 * updated FT support to use the latest draft, IEEE 802.11r/D8.0 704 * fixed an integer overflow issue in the ASN.1 parser used by the 705 (experimental) internal TLS implementation to avoid a potential 706 buffer read overflow 707 * fixed a race condition with -W option (wait for a control interface 708 monitor before starting) that could have caused the first messages to 709 be lost 710 * added support for processing TNCC-TNCS-Messages to report 711 recommendation (allow/none/isolate) when using TNC [Bug 243] 712 713 2007-05-28 - v0.6.0 714 * added network configuration parameter 'frequency' for setting 715 initial channel for IBSS (adhoc) networks 716 * added experimental IEEE 802.11r/D6.0 support 717 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48 718 * updated EAP-PSK to use the IANA-allocated EAP type 47 719 * fixed EAP-PAX key derivation 720 * fixed EAP-PSK bit ordering of the Flags field 721 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in 722 tunnelled identity request (previously, the identifier from the outer 723 method was used, not the tunnelled identifier which could be 724 different) 725 * added support for fragmentation of outer TLS packets during Phase 2 726 of EAP-PEAP/TTLS/FAST 727 * fixed EAP-TTLS AVP parser processing for too short AVP lengths 728 * added support for EAP-FAST authentication with inner methods that 729 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported 730 for PAC provisioning) 731 * added support for authenticated EAP-FAST provisioning 732 * added support for configuring maximum number of EAP-FAST PACs to 733 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string) 734 * added support for storing EAP-FAST PACs in binary format 735 (fast_pac_format=binary in phase1 string) 736 * fixed dbus ctrl_iface to validate message interface before 737 dispatching to avoid a possible segfault [Bug 190] 738 * fixed PeerKey key derivation to use the correct PRF label 739 * updated Windows binary build to link against OpenSSL 0.9.8d and 740 added support for EAP-FAST 741 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 742 draft (draft-ietf-emu-eap-gpsk-04.txt) 743 * fixed EAP-AKA Notification processing to allow Notification to be 744 processed after AKA Challenge response has been sent 745 * updated to use IEEE 802.11w/D2.0 for management frame protection 746 (still experimental) 747 * fixed EAP-TTLS implementation not to crash on use of freed memory 748 if TLS library initialization fails 749 * added support for EAP-TNC (Trusted Network Connect) 750 (this version implements the EAP-TNC method and EAP-TTLS changes 751 needed to run two methods in sequence (IF-T) and the IF-IMC and 752 IF-TNCCS interfaces from TNCC) 753 754 2006-11-24 - v0.5.6 755 * added experimental, integrated TLSv1 client implementation with the 756 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by 757 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in 758 .config); this can be useful, e.g., if the target system does not 759 have a suitable TLS library and a minimal code size is required 760 (total size of this internal TLS/crypto code is bit under 50 kB on 761 x86 and the crypto code is shared by rest of the supplicant so some 762 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB) 763 * removed STAKey handshake since PeerKey handshake has replaced it in 764 IEEE 802.11ma and there are no known deployments of STAKey 765 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 766 draft (draft-ietf-emu-eap-gpsk-01.txt) 767 * added preliminary implementation of IEEE 802.11w/D1.0 (management 768 frame protection) 769 (Note: this requires driver support to work properly.) 770 (Note2: IEEE 802.11w is an unapproved draft and subject to change.) 771 * fixed Windows named pipes ctrl_iface to not stop listening for 772 commands if client program opens a named pipe and closes it 773 immediately without sending a command 774 * fixed USIM PIN status determination for the case that PIN is not 775 needed (this allows EAP-AKA to be used with USIM cards that do not 776 use PIN) 777 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to 778 be used with cards that do not support file selection based on 779 partial AID 780 * added support for matching the subjectAltName of the authentication 781 server certificate against multiple name components (e.g., 782 altsubject_match="DNS:server.example.com;DNS:server2.example.com") 783 * fixed EAP-SIM/AKA key derivation for re-authentication case (only 784 affects IEEE 802.1X with dynamic WEP keys) 785 * changed ctrl_iface network configuration 'get' operations to not 786 return password/key material; if these fields are requested, "*" 787 will be returned if the password/key is set, but the value of the 788 parameter is not exposed 789 790 2006-08-27 - v0.5.5 791 * added support for building Windows version with UNICODE defined 792 (wide-char functions) 793 * driver_ndis: fixed static WEP configuration to avoid race condition 794 issues with some NDIS drivers between association and setting WEP 795 keys 796 * driver_ndis: added validation for IELength value in scan results to 797 avoid crashes when using buggy NDIS drivers [Bug 165] 798 * fixed Release|Win32 target in the Visual Studio project files 799 (previously, only Debug|Win32 target was set properly) 800 * changed control interface API call wpa_ctrl_pending() to allow it to 801 return -1 on error (e.g., connection lost); control interface clients 802 will need to make sure that they verify that the value is indeed >0 803 when determining whether there are pending messages 804 * added an alternative control interface backend for Windows targets: 805 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default 806 control interface mechanism for Windows builds (previously, UDP to 807 localhost was used) 808 * changed ctrl_interface configuration for UNIX domain sockets: 809 - deprecated ctrl_interface_group variable (it may be removed in 810 future versions) 811 - allow both directory and group be configured with ctrl_interface 812 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel 813 - ctrl_interface=/var/run/wpa_supplicant is still supported for the 814 case when group is not changed 815 * added support for controlling more than one interface per process in 816 Windows version 817 * added a workaround for a case where the AP is using unknown address 818 (e.g., MAC address of the wired interface) as the source address for 819 EAPOL-Key frames; previously, that source address was used as the 820 destination for EAPOL-Key frames and in key derivation; now, BSSID is 821 used even if the source address does not match with it 822 (this resolves an interoperability issue with Thomson SpeedTouch 580) 823 * added a workaround for UDP-based control interface (which was used in 824 Windows builds before this release) to prevent packets with forged 825 addresses from being accepted as local control requests 826 * removed ndis_events.cpp and possibility of using external 827 ndis_events.exe; C version (ndis_events.c) is fully functional and 828 there is no desire to maintain two separate versions of this 829 implementation 830 * ndis_events: Changed NDIS event notification design to use WMI to 831 learn the adapter description through Win32_PnPEntity class; this 832 should fix some cases where the adapter name was not recognized 833 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500 834 USB) [Bug 113] 835 * fixed selection of the first network in ap_scan=2 mode; previously, 836 wpa_supplicant could get stuck in SCANNING state when only the first 837 network for enabled (e.g., after 'wpa_cli select_network 0') 838 * winsvc: added support for configuring ctrl_interface parameters in 839 registry (ctrl_interface string value in 840 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is 841 required to enable control interface (previously, this was hardcoded 842 to be enabled) 843 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4 844 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format 845 846 2006-06-20 - v0.5.4 847 * fixed build with CONFIG_STAKEY=y [Bug 143] 848 * added support for doing MLME (IEEE 802.11 management frame 849 processing) in wpa_supplicant when using Devicescape IEEE 802.11 850 stack (wireless-dev.git tree) 851 * added a new network block configuration option, fragment_size, to 852 configure the maximum EAP fragment size 853 * driver_ndis: Disable WZC automatically for the selected interface to 854 avoid conflicts with two programs trying to control the radio; WZC 855 will be re-enabled (if it was enabled originally) when wpa_supplicant 856 is terminated 857 * added an experimental TLSv1 client implementation 858 (CONFIG_TLS=internal) that can be used instead of an external TLS 859 library, e.g., to reduce total size requirement on systems that do 860 not include any TLS library by default (this is not yet complete; 861 basic functionality is there, but certificate validation is not yet 862 included) 863 * added PeerKey handshake implementation for IEEE 802.11e 864 direct link setup (DLS) to replace STAKey handshake 865 * fixed WPA PSK update through ctrl_iface for the case where the old 866 PSK was derived from an ASCII passphrase and the new PSK is set as 867 a raw PSK (hex string) 868 * added new configuration option for identifying which network block 869 was used (id_str in wpa_supplicant.conf; included on 870 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental 871 variable in wpa_cli action scripts; in addition WPA_ID variable is 872 set to the current unique identifier that wpa_supplicant assigned 873 automatically for the network and that can be used with 874 GET_NETWORK/SET_NETWORK ctrl_iface commands) 875 * wpa_cli action script is now called only when the connect/disconnect 876 status changes or when associating with a different network 877 * fixed configuration parser not to remove CCMP from group cipher list 878 if WPA-None (adhoc) is used (pairwise=NONE in that case) 879 * fixed integrated NDIS events processing not to hang the process due 880 to a missed change in eloop_win.c API in v0.5.3 [Bug 155] 881 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK, 882 draft-clancy-emu-eap-shared-secret-00.txt) 883 * added Microsoft Visual Studio 2005 solution and project files for 884 build wpa_supplicant for Windows (see vs2005 subdirectory) 885 * eloop_win: fixed unregistration of Windows events 886 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet 887 at the end of RSN pre-authentication and added unregistration of 888 a Windows event to avoid getting eloop_win stuck with an invalid 889 handle 890 * driver_ndis: added support for selecting AP based on BSSID 891 * added new environmental variable for wpa_cli action scripts: 892 WPA_CTRL_DIR is the current control interface directory 893 * driver_ndis: added support for using NDISUIO instead of WinPcap for 894 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new 895 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build 896 wpa_supplicant without requiring WinPcap; note that using NDISUIO 897 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows 898 only one application to open the device 899 * changed NDIS driver naming to only include device GUID, e.g., 900 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap 901 specific \Device\NPF_ prefix before the GUID; the prefix is still 902 allowed for backwards compatibility, but it is not required anymore 903 when specifying the interface 904 * driver_ndis: re-initialize driver interface is the adapter is removed 905 and re-inserted [Bug 159] 906 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on 907 big endian hosts [Bug 146] 908 909 2006-04-27 - v0.5.3 910 * fixed EAP-GTC response to include correct user identity when run as 911 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2) 912 * driver_ndis: Fixed encryption mode configuration for unencrypted 913 networks (some NDIS drivers ignored this, but others, e.g., Broadcom, 914 refused to associate with open networks) [Bug 106] 915 * driver_ndis: use BSSID OID polling to detect when IBSS network is 916 formed even when ndis_events code is included since some NDIS drivers 917 do not generate media connect events in IBSS mode 918 * config_winreg: allow global ctrl_interface parameter to be configured 919 in Windows registry 920 * config_winreg: added support for saving configuration data into 921 Windows registry 922 * added support for controlling network device operational state 923 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see 924 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client 925 that can use this information) 926 * driver_wext: added support for WE-21 change to SSID configuration 927 * driver_wext: fixed privacy configuration for static WEP keys mode 928 [Bug 140] 929 * added an optional driver_ops callback for MLME-SETPROTECTION.request 930 primitive 931 * added support for EAP-SAKE (no EAP method number allocated yet, so 932 this is using the same experimental type 255 as EAP-PSK) 933 * added support for dynamically loading EAP methods (.so files) instead 934 of requiring them to be statically linked in; this is disabled by 935 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information 936 on how to use this) 937 938 2006-03-19 - v0.5.2 939 * do not try to use USIM APDUs when initializing PC/SC for SIM card 940 access for a network that has not enabled EAP-AKA 941 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in 942 v0.5.1 due to the new support for expanded EAP types) 943 * added support for generating EAP Expanded Nak 944 * try to fetch scan results once before requesting new scan when 945 starting up in ap_scan=1 mode (this can speed up initial association 946 a lot with, e.g., madwifi-ng driver) 947 * added support for receiving EAPOL frames from a Linux bridge 948 interface (-bbr0 on command line) 949 * fixed EAPOL re-authentication for sessions that used PMKSA caching 950 * changed EAP method registration to use a dynamic list of methods 951 instead of a static list generated at build time 952 * fixed PMKSA cache deinitialization not to use freed memory when 953 removing PMKSA entries 954 * fixed a memory leak in EAP-TTLS re-authentication 955 * reject WPA/WPA2 message 3/4 if it does not include any valid 956 WPA/RSN IE 957 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg 958 if the driver does not support SIOCSIWAUTH 959 960 2006-01-29 - v0.5.1 961 * driver_test: added better support for multiple APs and STAs by using 962 a directory with sockets that include MAC address for each device in 963 the name (driver_param=test_dir=/tmp/test) 964 * added support for EAP expanded type (vendor specific EAP methods) 965 * added AP_SCAN command into ctrl_iface so that ap_scan configuration 966 option can be changed if needed 967 * wpa_cli/wpa_gui: skip non-socket files in control directory when 968 using UNIX domain sockets; this avoids selecting an incorrect 969 interface (e.g., a PID file could be in this directory, even though 970 use of this directory for something else than socket files is not 971 recommended) 972 * fixed TLS library deinitialization after RSN pre-authentication not 973 to disable TLS library for normal authentication 974 * driver_wext: Remove null-termination from SSID length if the driver 975 used it; some Linux drivers do this and they were causing problems in 976 wpa_supplicant not finding matching configuration block. This change 977 would break a case where the SSID actually ends in '\0', but that is 978 not likely to happen in real use. 979 * fixed PMKSA cache processing not to trigger deauthentication if the 980 current PMKSA cache entry is replaced with a valid new entry 981 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes 982 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or 983 ap_scan=2) 984 985 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases) 986 * added experimental STAKey handshake implementation for IEEE 802.11e 987 direct link setup (DLS); note: this is disabled by default in both 988 build and runtime configuration (can be enabled with CONFIG_STAKEY=y 989 and stakey=1) 990 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to 991 decrypt AT_ENCR_DATA attributes correctly 992 * fixed EAP-AKA to allow resynchronization within the same session 993 * made code closer to ANSI C89 standard to make it easier to port to 994 other C libraries and compilers 995 * started moving operating system or C library specific functions into 996 wrapper functions defined in os.h and implemented in os_*.c to make 997 code more portable 998 * wpa_supplicant can now be built with Microsoft Visual C++ 999 (e.g., with the freely available Toolkit 2003 version or Visual 1000 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an 1001 example makefile for nmake 1002 * added support for using Windows registry for command line parameters 1003 (CONFIG_MAIN=main_winsvc) and configuration data 1004 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry 1005 contents; this version can be run both as a Windows service and as a 1006 normal application; 'wpasvc.exe app' to start as applicant, 1007 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service, 1008 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to 1009 unregister a service 1010 * made it possible to link ndis_events.exe functionality into 1011 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED 1012 * added better support for multiple control interface backends 1013 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported 1014 * fixed PC/SC code to use correct length for GSM AUTH command buffer 1015 and to not use pioRecvPci with SCardTransmit() calls; these were not 1016 causing visible problems with pcsc-lite, but Windows Winscard.dll 1017 refused the previously used parameters; this fixes EAP-SIM and 1018 EAP-AKA authentication using SIM/USIM card under Windows 1019 * added new event loop implementation for Windows using 1020 WaitForMultipleObject() instead of select() in order to allow waiting 1021 for non-socket objects; this can be selected with 1022 CONFIG_ELOOP=eloop_win in .config 1023 * added support for selecting l2_packet implementation in .config 1024 (CONFIG_L2_PACKET; following options are available now: linux, pcap, 1025 winpcap, freebsd, none) 1026 * added new l2_packet implementation for WinPcap 1027 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to 1028 reduce latency in EAPOL receive processing from about 100 ms to about 1029 3 ms 1030 * added support for EAP-FAST key derivation using other ciphers than 1031 RC4-128-SHA for authentication and AES128-SHA for provisioning 1032 * added support for configuring CA certificate as DER file and as a 1033 configuration blob 1034 * fixed private key configuration as configuration blob and added 1035 support for using PKCS#12 as a blob 1036 * tls_gnutls: added support for using PKCS#12 files; added support for 1037 session resumption 1038 * added support for loading trusted CA certificates from Windows 1039 certificate store: ca_cert="cert_store://<name>", where <name> is 1040 likely CA (Intermediate CA certificates) or ROOT (root certificates) 1041 * added C version of ndis_events.cpp and made it possible to build this 1042 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more 1043 easily on cross-compilation builds 1044 * added wpasvc.exe into Windows binary release; this is an alternative 1045 version of wpa_supplicant.exe with configuration backend using 1046 Windows registry and with the entry point designed to run as a 1047 Windows service 1048 * integrated ndis_events.exe functionality into wpa_supplicant.exe and 1049 wpasvc.exe and removed this additional tool from the Windows binary 1050 release since it is not needed anymore 1051 * load winscard.dll functions dynamically when building with MinGW 1052 since MinGW does not yet include winscard library 1053 1054 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases) 1055 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap 1056 and WinPcap to receive frames sent to PAE group address 1057 * disable EAP state machine when IEEE 802.1X authentication is not used 1058 in order to get rid of bogus "EAP failed" messages 1059 * fixed OpenSSL error reporting to go through all pending errors to 1060 avoid confusing reports of old errors being reported at later point 1061 during handshake 1062 * fixed configuration file updating to not write empty variables 1063 (e.g., proto or key_mgmt) that the file parser would not accept 1064 * fixed ADD_NETWORK ctrl_iface command to use the same default values 1065 for variables as empty network definitions read from config file 1066 would get 1067 * fixed EAP state machine to not discard EAP-Failure messages in many 1068 cases (e.g., during TLS handshake) 1069 * fixed a infinite loop in private key reading if the configured file 1070 cannot be parsed successfully 1071 * driver_madwifi: added support for madwifi-ng 1072 * wpa_gui: do not display password/PSK field contents 1073 * wpa_gui: added CA certificate configuration 1074 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID 1075 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if 1076 the new AP is using different WPA/RSN IE 1077 * use longer timeout for IEEE 802.11 association to avoid problems with 1078 drivers that may take more than five second to associate 1079 1080 2005-10-27 - v0.4.6 1081 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in 1082 RSN IE, but WPA IE would match with wpa_supplicant configuration 1083 * added support for named configuration blobs in order to avoid having 1084 to use file system for external files (e.g., certificates); 1085 variables can be set to "blob://<blob name>" instead of file path to 1086 use a named blob; supported fields: pac_file, client_cert, 1087 private_key 1088 * fixed RSN pre-authentication (it was broken in the clean up of WPA 1089 state machine interface in v0.4.5) 1090 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make 1091 sure the driver configures broadcast decryption correctly 1092 * added ca_path (and ca_path2) configuration variables that can be used 1093 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the 1094 system-wide trusted CA list 1095 * added support for starting wpa_supplicant without a configuration 1096 file (-C argument must be used to set ctrl_interface parameter for 1097 this case; in addition, -p argument can be used to provide 1098 driver_param; these new arguments can also be used with a 1099 configuration to override the values from the configuration) 1100 * added global control interface that can be optionally used for adding 1101 and removing network interfaces dynamically (-g command line argument 1102 for both wpa_supplicant and wpa_cli) without having to restart 1103 wpa_supplicant process 1104 * wpa_gui: 1105 - try to save configuration whenever something is modified 1106 - added WEP key configuration 1107 - added possibility to edit the current network configuration 1108 * driver_ndis: fixed driver polling not to increase frequency on each 1109 received EAPOL frame due to incorrectly cancelled timeout 1110 * added simple configuration file examples (in examples subdirectory) 1111 * fixed driver_wext.c to filter wireless events based on ifindex to 1112 avoid interfaces receiving events from other interfaces 1113 * delay sending initial EAPOL-Start couple of seconds to speed up 1114 authentication for the most common case of Authenticator starting 1115 EAP authentication immediately after association 1116 1117 2005-09-25 - v0.4.5 1118 * added a workaround for clearing keys with ndiswrapper to allow 1119 roaming from WPA enabled AP to plaintext one 1120 * added docbook documentation (doc/docbook) that can be used to 1121 generate, e.g., man pages 1122 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for 1123 PF_PACKET in order to prepare for network devices that do not use 1124 Ethernet headers (e.g., network stack with native IEEE 802.11 frames) 1125 * use receipt of EAPOL-Key frame as a lower layer success indication 1126 for EAP state machine to allow recovery from dropped EAP-Success 1127 frame 1128 * cleaned up internal EAPOL frame processing by not including link 1129 layer (Ethernet) header during WPA and EAPOL/EAP processing; this 1130 header is added only when transmitted the frame; this makes it easier 1131 to use wpa_supplicant on link layers that use different header than 1132 Ethernet 1133 * updated EAP-PSK to use draft 9 by default since this can now be 1134 tested with hostapd; removed support for draft 3, including 1135 server_nai configuration option from network blocks 1136 * driver_wired: add PAE address to the multicast address list in order 1137 to be able to receive EAPOL frames with drivers that do not include 1138 these multicast addresses by default 1139 * driver_wext: add support for WE-19 1140 * added support for multiple configuration backends (CONFIG_BACKEND 1141 option); currently, only 'file' is supported (i.e., the format used 1142 in wpa_supplicant.conf) 1143 * added support for updating configuration ('wpa_cli save_config'); 1144 this is disabled by default and can be enabled with global 1145 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli 1146 and wpa_gui to store the configuration changes in a permanent store 1147 * added GET_NETWORK ctrl_iface command 1148 (e.g., 'wpa_cli get_network 0 ssid') 1149 1150 2005-08-21 - v0.4.4 1151 * replaced OpenSSL patch for EAP-FAST support 1152 (openssl-tls-extensions.patch) with a more generic and correct 1153 patch (the new patch is not compatible with the previous one, so the 1154 OpenSSL library will need to be patched with the new patch in order 1155 to be able to build wpa_supplicant with EAP-FAST support) 1156 * added support for using Windows certificate store (through CryptoAPI) 1157 for client certificate and private key operations (EAP-TLS) 1158 (see wpa_supplicant.conf for more information on how to configure 1159 this with private_key) 1160 * ported wpa_gui to Windows 1161 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be 1162 built with the open source version of the Qt4 for Windows 1163 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used 1164 with drivers that do not support WPA 1165 * ndis_events: fixed Windows 2000 support 1166 * added support for enabling/disabling networks from the list of all 1167 configured networks ('wpa_cli enable_network <network id>' and 1168 'wpa_cli disable_network <network id>') 1169 * added support for adding and removing network from the current 1170 configuration ('wpa_cli add_network' and 'wpa_cli remove_network 1171 <network id>'); added networks are disabled by default and they can 1172 be enabled with enable_network command once the configuration is done 1173 for the new network; note: configuration file is not yet updated, so 1174 these new networks are lost when wpa_supplicant is restarted 1175 * added support for setting network configuration parameters through 1176 the control interface, for example: 1177 wpa_cli set_network 0 ssid "\"my network\"" 1178 * fixed parsing of strings that include both " and # within double 1179 quoted area (e.g., "start"#end") 1180 * added EAP workaround for PEAP session resumption: allow outer, 1181 i.e., not tunneled, EAP-Success to terminate session since; this can 1182 be disabled with eap_workaround=0 1183 (this was allowed for PEAPv1 before, but now it is also allowed for 1184 PEAPv0 since at least one RADIUS authentication server seems to be 1185 doing this for PEAPv0, too) 1186 * wpa_gui: added preliminary support for adding new networks to the 1187 wpa_supplicant configuration (double click on the scan results to 1188 open network configuration) 1189 1190 2005-06-26 - v0.4.3 1191 * removed interface for external EAPOL/EAP supplicant (e.g., 1192 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required 1193 anymore and is unlikely to be used by anyone 1194 * driver_ndis: fixed WinPcap 3.0 support 1195 * fixed build with CONFIG_DNET_PCAP=y on Linux 1196 * l2_packet: moved different implementations into separate files 1197 (l2_packet_*.c) 1198 1199 2005-06-12 - v0.4.2 1200 * driver_ipw: updated driver structures to match with ipw2200-1.0.4 1201 (note: ipw2100-1.1.0 is likely to require an update to work with 1202 this) 1203 * added support for using ap_scan=2 mode with multiple network blocks; 1204 wpa_supplicant will go through the networks one by one until the 1205 driver reports a successful association; this uses the same order for 1206 networks as scan_ssid=1 scans, i.e., the priority field is ignored 1207 and the network block order in the file is used instead 1208 * fixed a potential issue in RSN pre-authentication ending up using 1209 freed memory if pre-authentication times out 1210 * added support for matching alternative subject name extensions of the 1211 authentication server certificate; new configuration variables 1212 altsubject_match and altsubject_match2 1213 * driver_ndis: added support for IEEE 802.1X authentication with wired 1214 NDIS drivers 1215 * added support for querying private key password (EAP-TLS) through the 1216 control interface (wpa_cli/wpa_gui) if one is not included in the 1217 configuration file 1218 * driver_broadcom: fixed couple of memory leaks in scan result 1219 processing 1220 * EAP-PAX is now registered as EAP type 46 1221 * fixed EAP-PAX MAC calculation 1222 * fixed EAP-PAX CK and ICK key derivation 1223 * added support for using password with EAP-PAX (as an alternative to 1224 entering key with eappsk); SHA-1 hash of the password will be used as 1225 the key in this case 1226 * added support for arbitrary driver interface parameters through the 1227 configuration file with a new driver_param field; this adds a new 1228 driver_ops function set_param() 1229 * added possibility to override l2_packet module with driver interface 1230 API (new send_eapol handler); this can be used to implement driver 1231 specific TX/RX functions for EAPOL frames 1232 * fixed ctrl_interface_group processing for the case where gid is 1233 entered as a number, not group name 1234 * driver_test: added support for testing hostapd with wpa_supplicant 1235 by using test driver interface without any kernel drivers or network 1236 cards 1237 1238 2005-05-22 - v0.4.1 1239 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL 1240 packets to be encrypted; this was apparently broken by the changed 1241 ioctl order in v0.4.0 1242 * driver_madwifi: added preliminary support for compiling against 'BSD' 1243 branch of madwifi CVS tree 1244 * added support for EAP-MSCHAPv2 password retries within the same EAP 1245 authentication session 1246 * added support for password changes with EAP-MSCHAPv2 (used when the 1247 password has expired) 1248 * added support for reading additional certificates from PKCS#12 files 1249 and adding them to the certificate chain 1250 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys 1251 were used 1252 * fixed a possible double free in EAP-TTLS fast-reauthentication when 1253 identity or password is entered through control interface 1254 * display EAP Notification messages to user through control interface 1255 with "CTRL-EVENT-EAP-NOTIFICATION" prefix 1256 * added GUI version of wpa_cli, wpa_gui; this is not build 1257 automatically with 'make'; use 'make wpa_gui' to build (this requires 1258 Qt development tools) 1259 * added 'disconnect' command to control interface for setting 1260 wpa_supplicant in state where it will not associate before 1261 'reassociate' command has been used 1262 * added support for selecting a network from the list of all configured 1263 networks ('wpa_cli select_network <network id>'; this disabled all 1264 other networks; to re-enable, 'wpa_cli select_network any') 1265 * added support for getting scan results through control interface 1266 * added EAP workaround for PEAPv1 session resumption: allow outer, 1267 i.e., not tunneled, EAP-Success to terminate session since; this can 1268 be disabled with eap_workaround=0 1269 1270 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases) 1271 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be 1272 used to reduce the size of the wpa_supplicant considerably if 1273 debugging code is not needed 1274 * fixed EAPOL-Key validation to drop packets with invalid Key Data 1275 Length; such frames could have crashed wpa_supplicant due to buffer 1276 overflow 1277 * added support for wired authentication (IEEE 802.1X on wired 1278 Ethernet); driver interface 'wired' 1279 * obsoleted set_wpa() handler in the driver interface API (it can be 1280 replaced by moving enable/disable functionality into init()/deinit()) 1281 (calls to set_wpa() are still present for backwards compatibility, 1282 but they may be removed in the future) 1283 * driver_madwifi: fixed association in plaintext mode 1284 * modified the EAP workaround that accepts EAP-Success with incorrect 1285 Identifier to be even less strict about verification in order to 1286 interoperate with some authentication servers 1287 * added support for sending TLS alerts 1288 * added support for 'any' SSID wildcard; if ssid is not configured or 1289 is set to an empty string, any SSID will be accepted for non-WPA AP 1290 * added support for asking PIN (for SIM) from frontends (e.g., 1291 wpa_cli); if a PIN is needed, but not included in the configuration 1292 file, a control interface request is sent and EAP processing is 1293 delayed until the PIN is available 1294 * added support for using external devices (e.g., a smartcard) for 1295 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config); 1296 new wpa_supplicant.conf variables: 1297 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path 1298 - network: engine, engine_id, key_id 1299 * added experimental support for EAP-PAX 1300 * added monitor mode for wpa_cli (-a<path to a program to run>) that 1301 allows external commands (e.g., shell scripts) to be run based on 1302 wpa_supplicant events, e.g., when authentication has been completed 1303 and data connection is ready; other related wpa_cli arguments: 1304 -B (run in background), -P (write PID file); wpa_supplicant has a new 1305 command line argument (-W) that can be used to make it wait until a 1306 control interface command is received in order to avoid missing 1307 events 1308 * added support for opportunistic WPA2 PMKSA key caching (disabled by 1309 default, can be enabled with proactive_key_caching=1) 1310 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where 1311 Authenticator rejects PMKSA caching attempt and the driver is not 1312 using assoc_info events 1313 * added -P<pid file> argument for wpa_supplicant to write the current 1314 process id into a file 1315 1316 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases) 1317 * added new phase1 option parameter, include_tls_length=1, to force 1318 wpa_supplicant to add TLS Message Length field to all TLS messages 1319 even if the packet is not fragmented; this may be needed with some 1320 authentication servers 1321 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when 1322 using drivers that take care of AP selection (e.g., when using 1323 ap_scan=2) 1324 * fixed reprocessing of pending request after ctrl_iface requests for 1325 identity/password/otp 1326 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of 1327 EAP-PEAP and EAP-TTLS 1328 * all drivers using driver_wext: set interface up and select Managed 1329 mode when starting wpa_supplicant; set interface down when exiting 1330 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both 1331 ipw2100 and ipw2200; please note that this also changed the 1332 configuration variable in .config to CONFIG_DRIVER_IPW 1333 1334 2005-01-24 - v0.3.6 1335 * fixed a busy loop introduced in v0.3.5 for scan result processing 1336 when no matching AP is found 1337 1338 2005-01-23 - v0.3.5 1339 * added a workaround for an interoperability issue with a Cisco AP 1340 when using WPA2-PSK 1341 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as 1342 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow 1343 retransmission of dropped frames) 1344 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version 1345 (e.g., segfault when processing EAPOL-Key frames) 1346 * fixed EAP workaround and fast reauthentication configuration for 1347 RSN pre-authentication; previously these were disabled and 1348 pre-authentication would fail if the used authentication server 1349 requires EAP workarounds 1350 * added support for blacklisting APs that fail or timeout 1351 authentication in ap_scan=1 mode so that all APs are tried in cases 1352 where the ones with strongest signal level are failing authentication 1353 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS 1354 authentication attempt 1355 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded 1356 in the previous authentication (previously, only Phase 1 success was 1357 verified) 1358 1359 2005-01-09 - v0.3.4 1360 * added preliminary support for IBSS (ad-hoc) mode configuration 1361 (mode=1 in network block); this included a new key_mgmt mode 1362 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no 1363 key management; see wpa_supplicant.conf for more details and an 1364 example on how to configure this (note: this is currently implemented 1365 only for driver_hostapd.c, but the changes should be trivial to add 1366 in associate() handler for other drivers, too (assuming the driver 1367 supports WPA-None) 1368 * added preliminary port for native Windows (i.e., no cygwin) using 1369 mingw 1370 1371 2005-01-02 - v0.3.3 1372 * added optional support for GNU Readline and History Libraries for 1373 wpa_cli (CONFIG_READLINE) 1374 * cleaned up EAP state machine <-> method interface and number of 1375 small problems with error case processing not terminating on 1376 EAP-Failure but waiting for timeout 1377 * added couple of workarounds for interoperability issues with a 1378 Cisco AP when using WPA2 1379 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt); 1380 Note: This requires a patch for openssl to add support for TLS 1381 extensions and number of workarounds for operations without 1382 certificates. Proof of concept type of experimental patch is 1383 included in openssl-tls-extensions.patch. 1384 1385 2004-12-19 - v0.3.2 1386 * fixed private key loading for cases where passphrase is not set 1387 * fixed Windows/cygwin L2 packet handler freeing; previous version 1388 could cause a segfault when RSN pre-authentication was completed 1389 * added support for PMKSA caching with drivers that generate RSN IEs 1390 (e.g., NDIS); currently, this is only implemented in driver_ndis.c, 1391 but similar code can be easily added to driver_ndiswrapper.c once 1392 ndiswrapper gets full support for RSN PMKSA caching 1393 * improved recovery from PMKID mismatches by requesting full EAP 1394 authentication in case of failed PMKSA caching attempt 1395 * driver_ndis: added support for NDIS NdisMIncidateStatus() events 1396 (this requires that ndis_events is ran while wpa_supplicant is 1397 running) 1398 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys 1399 * added support for driver interfaces to replace the interface name 1400 based on driver/OS specific mapping, e.g., in case of driver_ndis, 1401 this allows the beginning of the adapter description to be used as 1402 the interface name 1403 * added support for CR+LF (Windows-style) line ends in configuration 1404 file 1405 * driver_ndis: enable radio before starting scanning, disable radio 1406 when exiting 1407 * modified association event handler to set portEnabled = FALSE before 1408 clearing port Valid in order to reset EAP state machine and avoid 1409 problems with new authentication getting ignored because of state 1410 machines ending up in AUTHENTICATED/SUCCESS state based on old 1411 information 1412 * added support for driver events to add PMKID candidates in order to 1413 allow drivers to give priority to most likely roaming candidates 1414 * driver_hostap: moved PrivacyInvoked configuration to associate() 1415 function so that this will not be set for plaintext connections 1416 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver 1417 interface can distinguish plaintext and IEEE 802.1X (no WPA) 1418 authentication 1419 * fixed static WEP key configuration to use broadcast/default type for 1420 all keys (previously, the default TX key was configured as pairwise/ 1421 unicast key) 1422 * driver_ndis: added legacy WPA capability detection for non-WPA2 1423 drivers 1424 * added support for setting static WEP keys for IEEE 802.1X without 1425 dynamic WEP keying (eapol_flags=0) 1426 1427 2004-12-12 - v0.3.1 1428 * added support for reading PKCS#12 (PFX) files (as a replacement for 1429 PEM/DER) to get certificate and private key (CONFIG_PKCS12) 1430 * fixed compilation with CONFIG_PCSC=y 1431 * added new ap_scan mode, ap_scan=2, for drivers that take care of 1432 association, but need to be configured with security policy and SSID, 1433 e.g., ndiswrapper and NDIS driver; this mode should allow such 1434 drivers to work with hidden SSIDs and optimized roaming; when 1435 ap_scan=2 is used, only the first network block in the configuration 1436 file is used and this configuration should have explicit security 1437 policy (i.e., only one option in the lists) for key_mgmt, pairwise, 1438 group, proto variables 1439 * added experimental port of wpa_supplicant for Windows 1440 - driver_ndis.c driver interface (NDIS OIDs) 1441 - currently, this requires cygwin and WinPcap 1442 - small utility, win_if_list, can be used to get interface name 1443 * control interface can now be removed at build time; add 1444 CONFIG_CTRL_IFACE=y to .config to maintain old functionality 1445 * optional Xsupplicant interface can now be removed at build time; 1446 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back) 1447 * added auth_alg to driver interface associate() parameters to make it 1448 easier for drivers to configure authentication algorithm as part of 1449 the association 1450 1451 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases) 1452 * driver_broadcom: added new driver interface for Broadcom wl.o driver 1453 (a generic driver for Broadcom IEEE 802.11a/g cards) 1454 * wpa_cli: fixed parsing of -p <path> command line argument 1455 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS 1456 ACK, not tunneled EAP-Success (of which only the first byte was 1457 actually send due to a bug in previous code); this seems to 1458 interoperate with most RADIUS servers that implements PEAPv1 1459 * PEAPv1: added support for terminating PEAP authentication on tunneled 1460 EAP-Success message; this can be configured by adding 1461 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf 1462 (some RADIUS servers require this whereas others require a tunneled 1463 reply 1464 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to 1465 the old label for key derivation; previously, the default was 1, 1466 but it looks like most existing PEAPv1 implementations use the old 1467 label which is thus more suitable default option 1468 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt) 1469 * fixed parsing of wep_tx_keyidx 1470 * added support for configuring list of allowed Phase 2 EAP types 1471 (for both EAP-PEAP and EAP-TTLS) instead of only one type 1472 * added support for configuring IEEE 802.11 authentication algorithm 1473 (auth_alg; mainly for using Shared Key authentication with static 1474 WEP keys) 1475 * added support for EAP-AKA (with UMTS SIM) 1476 * fixed couple of errors in PCSC handling that could have caused 1477 random-looking errors for EAP-SIM 1478 * added support for EAP-SIM pseudonyms and fast re-authentication 1479 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS 1480 session resumption) 1481 * added support for EAP-SIM with two challanges 1482 (phase1="sim_min_num_chal=3" can be used to require three challenges) 1483 * added support for configuring DH/DSA parameters for an ephemeral DH 1484 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters 1485 dh_file and dh_file2 (phase 2); this adds support for using DSA keys 1486 and optional DH key exchange to achieve forward secracy with RSA keys 1487 * added support for matching subject of the authentication server 1488 certificate with a substring when using EAP-TLS/PEAP/TTLS; new 1489 configuration variables subject_match and subject_match2 1490 * changed SSID configuration in driver_wext.c (used by many driver 1491 interfaces) to use ssid_len+1 as the length for SSID since some Linux 1492 drivers expect this 1493 * fixed couple of unaligned reads in scan result parsing to fix WPA 1494 connection on some platforms (e.g., ARM) 1495 * added driver interface for Intel ipw2100 driver 1496 * added support for LEAP with WPA 1497 * added support for larger scan results report (old limit was 4 kB of 1498 data, i.e., about 35 or so APs) when using Linux wireless extensions 1499 v17 or newer 1500 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start 1501 only if there is a PMKSA cache entry for the current AP 1502 * fixed error handling for case where reading of scan results fails: 1503 must schedule a new scan or wpa_supplicant will remain waiting 1504 forever 1505 * changed debug output to remove shared password/key material by 1506 default; all key information can be included with -K command line 1507 argument to match the previous behavior 1508 * added support for timestamping debug log messages (disabled by 1509 default, can be enabled with -t command line argument) 1510 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104 1511 if keys are not configured to be used; this fixes IEEE 802.1X mode 1512 with drivers that use this information to configure whether Privacy 1513 bit can be in Beacon frames (e.g., ndiswrapper) 1514 * avoid clearing driver keys if no keys have been configured since last 1515 key clear request; this seems to improve reliability of group key 1516 handshake for ndiswrapper & NDIS driver which seems to be suffering 1517 of some kind of timing issue when the keys are cleared again after 1518 association 1519 * changed driver interface API: 1520 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which 1521 version is being used (now, this is set to 2; previously, it was 1522 not defined) 1523 - pass pointer to private data structure to all calls 1524 - the new API is not backwards compatible; all in-tree driver 1525 interfaces has been converted to the new API 1526 * added support for controlling multiple interfaces (radios) per 1527 wpa_supplicant process; each interface needs to be listed on the 1528 command line (-c, -i, -D arguments) with -N as a separator 1529 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi) 1530 * added a workaround for EAP servers that incorrectly use same Id for 1531 sequential EAP packets 1532 * changed libpcap/libdnet configuration to use .config variable, 1533 CONFIG_DNET_PCAP, instead of requiring Makefile modification 1534 * improved downgrade attack detection in IE verification of msg 3/4: 1535 verify both WPA and RSN IEs, if present, not only the selected one; 1536 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or 1537 Probe Response frame, and RSN is enabled in wpa_supplicant 1538 configuration 1539 * fixed WPA msg 3/4 processing to allow Key Data field contain other 1540 IEs than just one WPA IE 1541 * added support for FreeBSD and driver interface for the BSD net80211 1542 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the 1543 required kernel mods have not yet been committed 1544 * made EAP workarounds configurable; enabled by default, can be 1545 disabled with network block option eap_workaround=0 1546 1547 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases) 1548 * resolved couple of interoperability issues with EAP-PEAPv1 and 1549 Phase 2 (inner EAP) fragment reassembly 1550 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the 1551 AP is using non-zero key index for the unicast key and key index zero 1552 for the broadcast key 1553 * driver_hostap: fixed IEEE 802.1X WEP key updates and 1554 re-authentication by allowing unencrypted EAPOL frames when not using 1555 WPA 1556 * added a new driver interface, 'wext', which uses only standard, 1557 driver independent functionality in Linux wireless extensions; 1558 currently, this can be used only for non-WPA IEEE 802.1X mode, but 1559 eventually, this is to be extended to support full WPA/WPA2 once 1560 Linux wireless extensions get support for this 1561 * added support for mode in which the driver is responsible for AP 1562 scanning and selection; this is disabled by default and can be 1563 enabled with global ap_scan=0 variable in wpa_supplicant.conf; 1564 this mode can be used, e.g., with generic 'wext' driver interface to 1565 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver 1566 supporting wireless extensions. 1567 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g., 1568 operation with an AP that does not include SSID in the Beacon frames) 1569 * added support for new EAP authentication methods: 1570 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP 1571 * added support for asking one-time-passwords from frontends (e.g., 1572 wpa_cli); this 'otp' command works otherwise like 'password' command, 1573 but the password is used only once and the frontend will be asked for 1574 a new password whenever a request from authenticator requires a 1575 password; this can be used with both EAP-OTP and EAP-GTC 1576 * changed wpa_cli to automatically re-establish connection so that it 1577 does not need to be re-started when wpa_supplicant is terminated and 1578 started again 1579 * improved user data (identity/password/otp) requests through 1580 frontends: process pending EAPOL packets after getting new 1581 information so that full authentication does not need to be 1582 restarted; in addition, send pending requests again whenever a new 1583 frontend is attached 1584 * changed control frontends to use a new directory for socket files to 1585 make it easier for wpa_cli to automatically select between interfaces 1586 and to provide access control for the control interface; 1587 wpa_supplicant.conf: ctrl_interface is now a path 1588 (/var/run/wpa_supplicant is the recommended path) and 1589 ctrl_interface_group can be used to select which group gets access to 1590 the control interface; 1591 wpa_cli: by default, try to connect to the first interface available 1592 in /var/run/wpa_supplicant; this path can be overriden with -p option 1593 and an interface can be selected with -i option (i.e., in most common 1594 cases, wpa_cli does not need to get any arguments) 1595 * added support for LEAP 1596 * added driver interface for Linux ndiswrapper 1597 * added priority option for network blocks in the configuration file; 1598 this allows networks to be grouped based on priority (the scan 1599 results are searched for matches with network blocks in this order) 1600 1601 2004-06-20 - v0.2.3 1602 * sort scan results to improve AP selection 1603 * fixed control interface socket removal for some error cases 1604 * improved scan requesting and authentication timeout 1605 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and 1606 TLS processing 1607 * PEAP version can now be forced with phase1="peapver=<ver>" 1608 (mostly for testing; by default, the highest version supported by 1609 both the Supplicant and Authentication Server is selected 1610 automatically) 1611 * added support for madwifi driver (Atheros ar521x) 1612 * added a workaround for cases where AP sets Install Tx/Rx bit for 1613 WPA Group Key messages when pairwise keys are used (without this, 1614 the Group Key would be used for Tx and the AP would drop frames 1615 from the station) 1616 * added GSM SIM/USIM interface for GSM authentication algorithm for 1617 EAP-SIM; this requires pcsc-lite 1618 * added support for ATMEL AT76C5XXx driver 1619 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator 1620 does not include key data in the EAPOL-Key frame (i.e., part of 1621 EAP keying material is used as data encryption key) 1622 * added support for using plaintext and static WEP networks 1623 (key_mgmt=NONE) 1624 1625 2004-05-31 - v0.2.2 1626 * added support for new EAP authentication methods: 1627 EAP-TTLS/EAP-MD5-Challenge 1628 EAP-TTLS/EAP-GTC 1629 EAP-TTLS/EAP-MSCHAPv2 1630 EAP-TTLS/EAP-TLS 1631 EAP-TTLS/MSCHAPv2 1632 EAP-TTLS/MSCHAP 1633 EAP-TTLS/PAP 1634 EAP-TTLS/CHAP 1635 EAP-PEAP/TLS 1636 EAP-PEAP/GTC 1637 EAP-PEAP/MD5-Challenge 1638 EAP-GTC 1639 EAP-SIM (not yet complete; needs GSM/SIM authentication interface) 1640 * added support for anonymous identity (to be used when identity is 1641 sent in plaintext; real identity will be used within TLS protected 1642 tunnel (e.g., with EAP-TTLS) 1643 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli 1644 * added support for requesting identity and password information using 1645 control interface; in other words, the password for EAP-PEAP or 1646 EAP-TTLS does not need to be included in the configuration file since 1647 a frontand (e.g., wpa_cli) can ask it from the user 1648 * improved RSN pre-authentication to use a candidate list and process 1649 all candidates from each scan; not only one per scan 1650 * fixed RSN IE and WPA IE capabilities field parsing 1651 * ignore Tx bit in GTK IE when Pairwise keys are used 1652 * avoid making new scan requests during IEEE 802.1X negotiation 1653 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant 1654 with TLS support (this replaces the included implementation with 1655 library code to save about 8 kB since the library code is needed 1656 anyway for TLS) 1657 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support 1658 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config) 1659 1660 2004-05-06 - v0.2.1 1661 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1) 1662 Supplicant 1663 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1] 1664 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf] 1665 - EAP-MD5 (cannot be used with WPA-RADIUS) 1666 [draft-ietf-eap-rfc2284bis-09.txt] 1667 - EAP-TLS [RFC 2716] 1668 - EAP-MSCHAPv2 (currently used only with EAP-PEAP) 1669 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt] 1670 [draft-kamath-pppext-eap-mschapv2-00.txt] 1671 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by 1672 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey) 1673 - new configuration file options: eap, identity, password, ca_cert, 1674 client_cert, privatekey, private_key_passwd 1675 - Xsupplicant is not required anymore, but it can be used by 1676 disabling the internal IEEE 802.1X Supplicant with -e command line 1677 option 1678 - this code is not included in the default build; Makefile need to 1679 be edited for this (uncomment lines for selected functionality) 1680 - EAP-TLS and EAP-PEAP require openssl libraries 1681 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..) 1682 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys 1683 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X 1684 EAPOL-Key frames instead of WPA key handshakes) 1685 * added support for IEEE 802.11i/RSN (WPA2) 1686 - improved PTK Key Handshake 1687 - PMKSA caching, pre-authentication 1688 * fixed wpa_supplicant to ignore possible extra data after WPA 1689 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using 1690 TPTK' error from message 3 of 4-Way Handshake in case the AP 1691 includes extra data after the EAPOL-Key) 1692 * added interface for external programs (frontends) to control 1693 wpa_supplicant 1694 - CLI example (wpa_cli) with interactive mode and command line 1695 mode 1696 - replaced SIGUSR1 status/statistics with the new control interface 1697 * made some feature compile time configurable 1698 - .config file for make 1699 - driver interfaces (hostap, hermes, ..) 1700 - EAPOL/EAP functions 1701 1702 2004-02-15 - v0.2.0 1703 * Initial version of wpa_supplicant 1704
