  63. * added workarounds for WPS PBC overlap detection for some P2P use cases
  64. where deployed stations work incorrectly
  65. * optimize WPS connection speed by disconnecting prior to WPS scan and
  66. by using single channel scans when AP channel is known
  67. * PCSC and SIM/USIM improvements:
  68. - accept 0x67 (Wrong length) as a response to READ RECORD to fix
  69. issues with some USIM cards
  70. - try to read MNC length from SIM/USIM

  213. compressed domain name format and support multiple Bonjour PTR matches
  214. for the same key
  215. * use deauthentication instead of disassociation for all disconnection
  216. operations; this removes the now unused disassociate() wpa_driver_ops

  219. multiple PBKDF2 operations
  220. * added okc=1 global configuration parameter to allow OKC to be enabled
  221. by default for all network blocks
  222. * added a workaround for WPS PBC session overlap detection to avoid

  275. cache expiration age and expiration scan count.
  276. - Add ability to set scan interval (the time in seconds wpa_s waits
  277. before requesting a new scan after failing to find a suitable
  278. network in scan results) using scan_interval command.
  279. - Add event CTRL-EVENT-ASSOC-REJECT for association rejected.
  280. - Add command get version, that returns wpa_supplicant version string.
  281. - Add command sta_autoconnect for disabling automatic reconnection
  282. on receiving disconnection event.
  283. - Setting bssid parameter to an empty string "" or any can now be
  284. used to clear the bssid_set flag in a network block, i.e., to remove
  285. bssid filtering.
  286. - Add tdls_testing command to add a special testing feature for
  287. changing TDLS behavior. Build param CONFIG_TDLS_TESTING must be
  288. enabled as well.

  300. line editing and history support. This can be used as a replacement
  301. for CONFIG_READLINE=y.
  302. * AP mode: Add max_num_sta config option, which can be used to limit
  303. the number of stations allowed to connect to the AP.
  304. * Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad
  305. config file.
  306. * wext: Increase scan timeout from 5 to 10 seconds.

  321. validate the checksum digit (if present).
  322. - Cancel WPS operation on PBC session overlap detection.
  323. - New wps_cancel command in wpa_cli will cancel a pending WPS
  324. operation.
  325. - wpa_cli action: Add WPS_EVENT_SUCCESS and WPS_EVENT_FAIL handlers.
  326. - Trigger WPS config update on Manufacturer, Model Name, Model
  327. Number, and Serial Number changes.
  328. - Fragment size is now configurable for EAP-WSC peer. Use
  329. wpa_cli set wps_fragment_size <val>.
  330. - Disable AP PIN after 10 consecutive failures. Slow down attacks on
  331. failures up to 10.
  332. - Allow AP to start in Enrollee mode without AP PIN for probing, to
  333. be compatible with Windows 7.
  334. - Add Config Error into WPS-FAIL events to provide more info to the
  335. user on how to resolve the issue.
  336. - Label and Display config methods are not allowed to be enabled
  337. at the same time, since it is unclear which PIN to use if both
  338. methods are advertised.
  339. - When controlling multiple interfaces:
  340. - apply WPS commands to all interfaces configured to use WPS
  341. - apply WPS config changes to all interfaces that use WPS
  342. - when an attack is detected on any interface, disable AP PIN on
  343. all interfaces
  344. * WPS ER:
  345. - Add special AP Setup Locked mode to allow read only ER.
  346. ap_setup_locked=2 can now be used to enable a special mode where
  347. WPS ER can learn the current AP settings, but cannot change them.
  348. - Show SetSelectedRegistrar events as ctrl_iface events
  349. - Add wps_er_set_config to enroll a network based on a local
  350. network configuration block instead of having to (re-)learn the
  351. current AP settings with wps_er_learn.
  352. - Allow AP filtering based on IP address, add ctrl_iface event for
  353. learned AP settings, add wps_er_config command to configure an AP.

  359. - Add support for AuthorizedMACs attribute.
  360. * TDLS:
  361. - Propogate TDLS related nl80211 capability flags from kernel and
  362. add them as driver capability flags. If the driver doesn't support
  363. capabilities, assume TDLS is supported internally. When TDLS is
  364. explicitly not supported, disable all user facing TDLS operations.
  365. - Allow TDLS to be disabled at runtime (mostly for testing).
  366. Use set tdls_disabled.
  367. - Honor AP TDLS settings that prohibit/allow TDLS.
  368. - Add a special testing feature for changing TDLS behavior. Use
  369. CONFIG_TDLS_TESTING build param to enable. Configure at runtime
  370. with tdls_testing cli command.
  371. - Add support for TDLS 802.11z.
  372. * wlantest: Add a tool wlantest for IEEE802.11 protocol testing.
  373. wlantest can be used to capture frames from a monitor interface
  374. for realtime capturing or from pcap files for offline analysis.
  375. * Interworking: Support added for 802.11u. Enable in .config with
  376. CONFIG_INTERWORKING. See wpa_supplicant.conf for config parameters
  377. for interworking. wpa_cli commands added to support this are
  378. interworking_select, interworking_connect, anqp_get, fetch_anqp,
  379. and stop_fetch_anqp.
  380. * Android: Add build and runtime support for Android wpa_supplicant.
  381. * bgscan learn: Add new bgscan that learns BSS information based on
  382. previous scans, and uses that information to dynamically generate
  383. the list of channels for background scans.
  384. * Add a new debug message level for excessive information. Use
  385. -ddd to enable.
  386. * TLS: Add support for tls_disable_time_checks=1 in client mode.
  387. * Internal TLS:
  388. - Add support for TLS v1.1 (RFC 4346). Enable with build parameter
  389. CONFIG_TLSV11.
  390. - Add domainComponent parser for X.509 names.
  391. * Linux: Add RFKill support by adding an interface state "disabled".

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