| Disassoc frames (nl80211). |
| * Drop oldest unknown BSS table entries first. This makes it less |
| likely to hit connection issues in environments with huge number |
| of visible APs. |
| * Add systemd support. |
| * Add support for setting the syslog facility from the config file |
| at build time. |
| * atheros: Add support for IEEE 802.11w configuration. |
| * AP mode: Allow enable HT20 if driver supports it, by setting the |
| config parameter ieee80211n. |
| * Allow AP mode to disconnect STAs based on low ACK condition (when |
| the data connection is not working properly, e.g., due to the STA |
| going outside the range of the AP). Disabled by default, enable by |
| config option disassoc_low_ack. |
| * nl80211: |
| - Support GTK rekey offload. |
| - Support PMKSA candidate events. This adds support for RSN |
| pre-authentication with nl80211 interface and drivers that handle |
| roaming internally. |

| * wpa_cli: |
| - Send AP-STA-DISCONNECTED event when an AP disconnects a station |
| due to inactivity. |
| - Make second argument to set command optional. This can be used to |
| indicate a zero length value. |
| - Add signal_poll command. |
| - Add bss_expire_age and bss_expire_count commands to set/get BSS |
| cache expiration age and expiration scan count. |
| - Add ability to set scan interval (the time in seconds wpa_s waits |
| before requesting a new scan after failing to find a suitable |
| network in scan results) using scan_interval command. |
| - Add event CTRL-EVENT-ASSOC-REJECT for association rejected. |
| - Add command get version, that returns wpa_supplicant version string. |
| - Add command sta_autoconnect for disabling automatic reconnection |
| on receiving disconnection event. |
| - Setting bssid parameter to an empty string "" or any can now be |
| used to clear the bssid_set flag in a network block, i.e., to remove |
| bssid filtering. |
| - Add tdls_testing command to add a special testing feature for |
| changing TDLS behavior. Build param CONFIG_TDLS_TESTING must be |
| enabled as well. |
| - For interworking, add wpa_cli commands interworking_select, |
| interworking_connect, anqp_get, fetch_anqp, and stop_fetch_anqp. |
| - Many P2P commands were added. See README-P2P. |
| - Many WPS/WPS ER commands - see WPS/WPS ER sections for details. |

| - Add log_level command, which can be used to display the current |
| debugging level and to change the log level during run time. |
| - Add note command, which can be used to insert notes to the debug |
| log. |
| - Add internal line edit implementation. CONFIG_WPA_CLI_EDIT=y |
| can now be used to build wpa_cli with internal implementation of |
| line editing and history support. This can be used as a replacement |
| for CONFIG_READLINE=y. |
| * AP mode: Add max_num_sta config option, which can be used to limit |
| the number of stations allowed to connect to the AP. |
| * Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad |
| config file. |
| * wext: Increase scan timeout from 5 to 10 seconds. |
| * Add blacklist command, allowing an external program to |
| manage the BSS blacklist and display its current contents. |
| * WPS: |
| - Add wpa_cli wps_pin get command for generating random PINs. This can |
| be used in a UI to generate a PIN without starting WPS (or P2P) |
| operation. |
| - Set RF bands based on driver capabilities, instead of hardcoding |
| them. |
| - Add mechanism for indicating non-standard WPS errors. |

| failures up to 10. |
| - Allow AP to start in Enrollee mode without AP PIN for probing, to |
| be compatible with Windows 7. |
| - Add Config Error into WPS-FAIL events to provide more info to the |
| user on how to resolve the issue. |
| - Label and Display config methods are not allowed to be enabled |
| at the same time, since it is unclear which PIN to use if both |
| methods are advertised. |
| - When controlling multiple interfaces: |
| - apply WPS commands to all interfaces configured to use WPS |
| - apply WPS config changes to all interfaces that use WPS |
| - when an attack is detected on any interface, disable AP PIN on |
| all interfaces |
| * WPS ER: |
| - Add special AP Setup Locked mode to allow read only ER. |
| ap_setup_locked=2 can now be used to enable a special mode where |
| WPS ER can learn the current AP settings, but cannot change them. |
| - Show SetSelectedRegistrar events as ctrl_iface events |
| - Add wps_er_set_config to enroll a network based on a local |
| network configuration block instead of having to (re-)learn the |
| current AP settings with wps_er_learn. |
| - Allow AP filtering based on IP address, add ctrl_iface event for |
| learned AP settings, add wps_er_config command to configure an AP. |
| * WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2) |
| - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool |
| for testing protocol extensibility. |
| - Add build option CONFIG_WPS_STRICT to allow disabling of WPS |
| workarounds. |
| - Add support for AuthorizedMACs attribute. |
| * TDLS: |
| - Propogate TDLS related nl80211 capability flags from kernel and |
| add them as driver capability flags. If the driver doesn't support |
| capabilities, assume TDLS is supported internally. When TDLS is |
| explicitly not supported, disable all user facing TDLS operations. |
| - Allow TDLS to be disabled at runtime (mostly for testing). |
| Use set tdls_disabled. |
| - Honor AP TDLS settings that prohibit/allow TDLS. |
| - Add a special testing feature for changing TDLS behavior. Use |
| CONFIG_TDLS_TESTING build param to enable. Configure at runtime |
| with tdls_testing cli command. |
| - Add support for TDLS 802.11z. |
| * wlantest: Add a tool wlantest for IEEE802.11 protocol testing. |
| wlantest can be used to capture frames from a monitor interface |
| for realtime capturing or from pcap files for offline analysis. |
| * Interworking: Support added for 802.11u. Enable in .config with |
| CONFIG_INTERWORKING. See wpa_supplicant.conf for config parameters |
| for interworking. wpa_cli commands added to support this are |
| interworking_select, interworking_connect, anqp_get, fetch_anqp, |
| and stop_fetch_anqp. |
| * Android: Add build and runtime support for Android wpa_supplicant. |
| * bgscan learn: Add new bgscan that learns BSS information based on |
| previous scans, and uses that information to dynamically generate |
| the list of channels for background scans. |
| * Add a new debug message level for excessive information. Use |
| -ddd to enable. |
| * TLS: Add support for tls_disable_time_checks=1 in client mode. |

| CONFIG_TLSV11. |
| - Add domainComponent parser for X.509 names. |
| * Linux: Add RFKill support by adding an interface state "disabled". |
| * Reorder some IEs to get closer to IEEE 802.11 standard. Move |
| WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames. |
| Move HT IEs to be later in (Re)Assoc Resp. |
| * Solaris: Add support for wired 802.1X client. |
| * Wi-Fi Direct support. See README-P2P for more information. |
| * Many bugfixes. |
| |
| 2010-04-18 - v0.7.2 |
| * nl80211: fixed number of issues with roaming |
| * avoid unnecessary roaming if multiple APs with similar signal |
| strength are present in scan results |
| * add TLS client events and server probing to ease design of |
| automatic detection of EAP parameters |
| * add option for server certificate matching (SHA256 hash of the |
| certificate) instead of trusted CA certificate configuration |
| * bsd: Cleaned up driver wrapper and added various low-level |
| configuration options |
| * wpa_gui-qt4: do not show too frequent WPS AP available events as |
| tray messages |
| * TNC: fixed issues with fragmentation |
| * EAP-TNC: add Flags field into fragment acknowledgement (needed to |
| interoperate with other implementations; may potentially breaks |
| compatibility with older wpa_supplicant/hostapd versions) |
| * wpa_cli: added option for using a separate process to receive event |
| messages to reduce latency in showing these |
| (CFLAGS += -DCONFIG_WPA_CLI_FORK=y in .config to enable this) |
| * maximum BSS table size can now be configured (bss_max_count) |
| * BSSes to be included in the BSS table can be filtered based on |
| configured SSIDs to save memory (filter_ssids) |
| * fix number of issues with IEEE 802.11r/FT; this version is not |
| backwards compatible with old versions |
| * nl80211: add support for IEEE 802.11r/FT protocol (both over-the-air |
| and over-the-DS) |
| * add freq_list network configuration parameter to allow the AP |
| selection to filter out entries based on the operating channel |
| * add signal strength change events for bgscan; this allows more |
| dynamic changes to background scanning interval based on changes in |
| the signal strength with the current AP; this improves roaming within |
| ESS quite a bit, e.g., with bgscan="simple:30:-45:300" in the network |
| configuration block to request background scans less frequently when |
| signal strength remains good and to automatically trigger background |
| scans whenever signal strength drops noticeably |
| (this is currently only available with nl80211) |
| * add BSSID and reason code (if available) to disconnect event messages |
| * wpa_gui-qt4: more complete support for translating the GUI with |
| linguist and add German translation |
| * fix DH padding with internal crypto code (mainly, for WPS) |
| * do not trigger initial scan automatically anymore if there are no |
| enabled networks |
| |
| 2010-01-16 - v0.7.1 |
| * cleaned up driver wrapper API (struct wpa_driver_ops); the new API |
| is not fully backwards compatible, so out-of-tree driver wrappers |
| will need modifications |
| * cleaned up various module interfaces |
| * merge hostapd and wpa_supplicant developers' documentation into a |
| single document |
| * nl80211: use explicit deauthentication to clear cfg80211 state to |
| avoid issues when roaming between APs |
| * dbus: major design changes in the new D-Bus API |
| (fi.w1.wpa_supplicant1) |
| * nl80211: added support for IBSS networks |
| * added internal debugging mechanism with backtrace support and memory |
| allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y) |
| * added WPS ER unsubscription command to more cleanly unregister from |
| receiving UPnP events when ER is terminated |
| * cleaned up AP mode operations to avoid need for virtual driver_ops |
| wrapper |
| * added BSS table to maintain more complete scan result information |
| over multiple scans (that may include only partial results) |
| * wpa_gui-qt4: update Peers dialog information more dynamically while |
| the dialog is kept open |
| * fixed PKCS#12 use with OpenSSL 1.0.0 |
| * driver_wext: Added cfg80211-specific optimization to avoid some |
| unnecessary scans and to speed up association |
| |
| 2009-11-21 - v0.7.0 |
| * increased wpa_cli ping interval to 5 seconds and made this |
| configurable with a new command line options (-G<seconds>) |
| * fixed scan buffer processing with WEXT to handle up to 65535 |
| byte result buffer (previously, limited to 32768 bytes) |
| * allow multiple driver wrappers to be specified on command line |
| (e.g., -Dnl80211,wext); the first one that is able to initialize the |
| interface will be used |
| * added support for multiple SSIDs per scan request to optimize |
| scan_ssid=1 operations in ap_scan=1 mode (i.e., search for hidden |
| SSIDs); this requires driver support and can currently be used only |
| with nl80211 |
| * added support for WPS USBA out-of-band mechanism with USB Flash |
| Drives (UFD) (CONFIG_WPS_UFD=y) |
| * driver_ndis: add PAE group address to the multicast address list to |
| fix wired IEEE 802.1X authentication |
| * fixed IEEE 802.11r key derivation function to match with the standard |
| (note: this breaks interoperability with previous version) [Bug 303] |
| * added better support for drivers that allow separate authentication |
| and association commands (e.g., mac80211-based Linux drivers with |
| nl80211; SME in wpa_supplicant); this allows over-the-air FT protocol |
| to be used (IEEE 802.11r) |
| * fixed SHA-256 based key derivation function to match with the |
| standard when using CCMP (for IEEE 802.11r and IEEE 802.11w) |
| (note: this breaks interoperability with previous version) [Bug 307] |
| * use shared driver wrapper files with hostapd |
| * added AP mode functionality (CONFIG_AP=y) with mode=2 in the network |
| block; this can be used for open and WPA2-Personal networks |
| (optionally, with WPS); this links in parts of hostapd functionality |
| into wpa_supplicant |
| * wpa_gui-qt4: added new Peers dialog to show information about peers |
| (other devices, including APs and stations, etc. in the neighborhood) |
| * added support for WPS External Registrar functionality (configure APs |
| and enroll new devices); can be used with wpa_gui-qt4 Peers dialog |
| and wpa_cli commands wps_er_start, wps_er_stop, wps_er_pin, |
| wps_er_pbc, wps_er_learn |
| (this can also be used with a new 'none' driver wrapper if no |
| wireless device or IEEE 802.1X on wired is needed) |
| * driver_nl80211: multiple updates to provide support for new Linux |
| nl80211/mac80211 functionality |
| * updated management frame protection to use IEEE Std 802.11w-2009 |
| * fixed number of small WPS issues and added workarounds to |
| interoperate with common deployed broken implementations |
| * added support for NFC out-of-band mechanism with WPS |
| * driver_ndis: fixed wired IEEE 802.1X authentication with PAE group |
| address frames |
| * added preliminary support for IEEE 802.11r RIC processing |
| * added support for specifying subset of enabled frequencies to scan |
| (scan_freq option in the network configuration block); this can speed |
| up scanning process considerably if it is known that only a small |
| subset of channels is actually used in the network (this is currently |
| supported only with -Dnl80211) |
| * added a workaround for race condition between receiving the |
| association event and the following EAPOL-Key |
| * added background scan and roaming infrastructure to allow |
| network-specific optimizations to be used to improve roaming within |
| an ESS (same SSID) |
| * added new DBus interface (fi.w1.wpa_supplicant1) |
| |
| 2009-01-06 - v0.6.7 |
| * added support for Wi-Fi Protected Setup (WPS) |
| (wpa_supplicant can now be configured to act as a WPS Enrollee to |
| enroll credentials for a network using PIN and PBC methods; in |
| addition, wpa_supplicant can act as a wireless WPS Registrar to |
| configure an AP); WPS support can be enabled by adding CONFIG_WPS=y |
| into .config and setting the runtime configuration variables in |
| wpa_supplicant.conf (see WPS section in the example configuration |
| file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to |
| manage WPS negotiation; see README-WPS for more details |
| * added support for EAP-AKA' (draft-arkko-eap-aka-kdf) |
| * added support for using driver_test over UDP socket |
| * fixed PEAPv0 Cryptobinding interoperability issue with Windows Server |
| 2008 NPS; optional cryptobinding is now enabled (again) by default |
| * fixed PSK editing in wpa_gui |
| * changed EAP-GPSK to use the IANA assigned EAP method type 51 |
| * added a Windows installer that includes WinPcap and all the needed |
| DLLs; in addition, it set up the registry automatically so that user |
| will only need start wpa_gui to get prompted to start the wpasvc |
| servide and add a new interface if needed through wpa_gui dialog |
| * updated management frame protection to use IEEE 802.11w/D7.0 |
| |
| 2008-11-23 - v0.6.6 |
| * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA |
| (can be used to simulate test SIM/USIM card with a known private key; |
| enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config |
| and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration) |
| * added a new network configuration option, wpa_ptk_rekey, that can be |
| used to enforce frequent PTK rekeying, e.g., to mitigate some attacks |
| against TKIP deficiencies |
| * added an optional mitigation mechanism for certain attacks against |
| TKIP by delaying Michael MIC error reports by a random amount of time |
| between 0 and 60 seconds; this can be enabled with a build option |
| CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config |
| * fixed EAP-AKA to use RES Length field in AT_RES as length in bits, |
| not bytes |
| * updated OpenSSL code for EAP-FAST to use an updated version of the |
| session ticket overriding API that was included into the upstream |
| OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is |
| needed with that version anymore) |
| * updated userspace MLME instructions to match with the current Linux |
| mac80211 implementation; please also note that this can only be used |
| with driver_nl80211.c (the old code from driver_wext.c was removed) |
| * added support (Linux only) for RoboSwitch chipsets (often found in |
| consumer grade routers); driver interface 'roboswitch' |
| * fixed canceling of PMKSA caching when using drivers that generate |
| RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know |
| about |
| |
| 2008-11-01 - v0.6.5 |
| * added support for SHA-256 as X.509 certificate digest when using the |
| internal X.509/TLSv1 implementation |
| * updated management frame protection to use IEEE 802.11w/D6.0 |
| * added support for using SHA256-based stronger key derivation for WPA2 |
| (IEEE 802.11w) |
| * fixed FT (IEEE 802.11r) authentication after a failed association to |
| use correct FTIE |
| * added support for configuring Phase 2 (inner/tunneled) authentication |
| method with wpa_gui-qt4 |
| |
| 2008-08-10 - v0.6.4 |
| * added support for EAP Sequences in EAP-FAST Phase 2 |
| * added support for using TNC with EAP-FAST |
| * added driver_ps3 for the PS3 Linux wireless driver |
| * added support for optional cryptobinding with PEAPv0 |
| * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to |
| allow fallback to full handshake if server rejects PAC-Opaque |
| * added fragmentation support for EAP-TNC |
| * added support for parsing PKCS #8 formatted private keys into the |
| internal TLS implementation (both PKCS #1 RSA key and PKCS #8 |
| encapsulated RSA key can now be used) |
| * added option of using faster, but larger, routines in the internal |
| LibTomMath (for internal TLS implementation) to speed up DH and RSA |
| calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y) |
| * fixed race condition between disassociation event and group key |
| handshake to avoid getting stuck in incorrect state [Bug 261] |
| * fixed opportunistic key caching (proactive_key_caching) |
| |
| 2008-02-22 - v0.6.3 |
| * removed 'nai' and 'eappsk' network configuration variables that were |
| previously used for configuring user identity and key for EAP-PSK, |
| EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the |
| replacement for 'nai' (if old configuration used a separate |
| 'identity' value, that would now be configured as |
| 'anonymous_identity'). 'password' field is now used as the |
| replacement for 'eappsk' (it can also be set using hexstring to |
| present random binary data) |
| * removed '-w' command line parameter (wait for interface to be added, |
| if needed); cleaner way of handling this functionality is to use an |
| external mechanism (e.g., hotplug scripts) that start wpa_supplicant |
| when an interface is added |
| * updated FT support to use the latest draft, IEEE 802.11r/D9.0 |
| * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for |
| indicating when new scan results become available |
| * added new ctrl_iface command, BSS, to allow scan results to be |
| fetched without hitting the message size limits (this command |
| can be used to iterate through the scan results one BSS at the time) |
| * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION |
| attributes in EAP-SIM Start/Response when using fast reauthentication |
| * fixed EAPOL not to end up in infinite loop when processing dynamic |
| WEP keys with IEEE 802.1X |
| * fixed problems in getting NDIS events from WMI on Windows 2000 |
| |
| 2008-01-01 - v0.6.2 |
| * added support for Makefile builds to include debug-log-to-a-file |
| functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line) |
| * fixed EAP-SIM and EAP-AKA message parser to validate attribute |
| lengths properly to avoid potential crash caused by invalid messages |
| * added data structure for storing allocated buffers (struct wpabuf); |
| this does not affect wpa_supplicant usage, but many of the APIs |
| changed and various interfaces (e.g., EAP) is not compatible with old |
| versions |
| * added support for protecting EAP-AKA/Identity messages with |
| AT_CHECKCODE (optional feature in RFC 4187) |
| * added support for protected result indication with AT_RESULT_IND for |
| EAP-SIM and EAP-AKA (phase1="result_ind=1") |
| * added driver_wext workaround for race condition between scanning and |
| association with drivers that take very long time to scan all |
| channels (e.g., madwifi with dual-band cards); wpa_supplicant is now |
| using a longer hardcoded timeout for the scan if the driver supports |
| notifications for scan completion (SIOCGIWSCAN event); this helps, |
| e.g., in cases where wpa_supplicant and madwifi driver ended up in |
| loop where the driver did not even try to associate |
| * stop EAPOL timer tick when no timers are in use in order to reduce |
| power consumption (no need to wake up the process once per second) |
| [Bug 237] |
| * added support for privilege separation (run only minimal part of |
| wpa_supplicant functionality as root and rest as unprivileged, |
| non-root process); see 'Privilege separation' in README for details; |
| this is disabled by default and can be enabled with CONFIG_PRIVSEP=y |
| in .config |
| * changed scan results data structure to include all information |
| elements to make it easier to support new IEs; old get_scan_result() |
| driver_ops is still supported for backwards compatibility (results |
| are converted internally to the new format), but all drivers should |
| start using the new get_scan_results2() to make them more likely to |
| work with new features |
| * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4 |
| application, i.e., it does not require Qt3Support anymore; Windows |
| binary of wpa_gui.exe is now from this directory and only requires |
| QtCore4.dll and QtGui4.dll libraries |
| * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs |
| available as a separate package to make wpa_gui installation easier: |
| http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip |
| * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt); |
| only shared key/password authentication is supported in this version |
| |
| 2007-11-24 - v0.6.1 |
| * added support for configuring password as NtPasswordHash |
| (16-byte MD4 hash of password) in hash:<32 hex digits> format |
| * added support for fallback from abbreviated TLS handshake to |
| full handshake when using EAP-FAST (e.g., due to an expired |
| PAC-Opaque) |
| * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest |
| draft (draft-ietf-emu-eap-gpsk-07.txt) |
| * added support for drivers that take care of RSN 4-way handshake |
| internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and |
| WPA_ALG_PMK in set_key) |
| * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in |
| .config); this version supports only ap_scan=2 mode and allow the |
| driver to take care of the 4-way handshake |
| * fixed a buffer overflow in parsing TSF from scan results when using |
| driver_wext.c with a driver that includes the TSF (e.g., iwl4965) |
| [Bug 232] |
| * updated FT support to use the latest draft, IEEE 802.11r/D8.0 |
| * fixed an integer overflow issue in the ASN.1 parser used by the |
| (experimental) internal TLS implementation to avoid a potential |
| buffer read overflow |
| * fixed a race condition with -W option (wait for a control interface |
| monitor before starting) that could have caused the first messages to |
| be lost |
| * added support for processing TNCC-TNCS-Messages to report |
| recommendation (allow/none/isolate) when using TNC [Bug 243] |
| |
| 2007-05-28 - v0.6.0 |
| * added network configuration parameter 'frequency' for setting |
| initial channel for IBSS (adhoc) networks |
| * added experimental IEEE 802.11r/D6.0 support |
| * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48 |
| * updated EAP-PSK to use the IANA-allocated EAP type 47 |
| * fixed EAP-PAX key derivation |
| * fixed EAP-PSK bit ordering of the Flags field |
| * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in |
| tunnelled identity request (previously, the identifier from the outer |
| method was used, not the tunnelled identifier which could be |
| different) |
| * added support for fragmentation of outer TLS packets during Phase 2 |
| of EAP-PEAP/TTLS/FAST |
| * fixed EAP-TTLS AVP parser processing for too short AVP lengths |
| * added support for EAP-FAST authentication with inner methods that |
| generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported |
| for PAC provisioning) |
| * added support for authenticated EAP-FAST provisioning |
| * added support for configuring maximum number of EAP-FAST PACs to |
| store in a PAC list (fast_max_pac_list_len=<max> in phase1 string) |
| * added support for storing EAP-FAST PACs in binary format |
| (fast_pac_format=binary in phase1 string) |
| * fixed dbus ctrl_iface to validate message interface before |
| dispatching to avoid a possible segfault [Bug 190] |
| * fixed PeerKey key derivation to use the correct PRF label |
| * updated Windows binary build to link against OpenSSL 0.9.8d and |
| added support for EAP-FAST |
| * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest |
| draft (draft-ietf-emu-eap-gpsk-04.txt) |
| * fixed EAP-AKA Notification processing to allow Notification to be |
| processed after AKA Challenge response has been sent |
| * updated to use IEEE 802.11w/D2.0 for management frame protection |
| (still experimental) |
| * fixed EAP-TTLS implementation not to crash on use of freed memory |
| if TLS library initialization fails |
| * added support for EAP-TNC (Trusted Network Connect) |
| (this version implements the EAP-TNC method and EAP-TTLS changes |
| needed to run two methods in sequence (IF-T) and the IF-IMC and |
| IF-TNCCS interfaces from TNCC) |
| |
| 2006-11-24 - v0.5.6 |
| * added experimental, integrated TLSv1 client implementation with the |
| needed X.509/ASN.1/RSA/bignum processing (this can be enabled by |
| setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in |
| .config); this can be useful, e.g., if the target system does not |
| have a suitable TLS library and a minimal code size is required |
| (total size of this internal TLS/crypto code is bit under 50 kB on |
| x86 and the crypto code is shared by rest of the supplicant so some |
| of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB) |
| * removed STAKey handshake since PeerKey handshake has replaced it in |
| IEEE 802.11ma and there are no known deployments of STAKey |
| * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest |
| draft (draft-ietf-emu-eap-gpsk-01.txt) |
| * added preliminary implementation of IEEE 802.11w/D1.0 (management |
| frame protection) |
| (Note: this requires driver support to work properly.) |
| (Note2: IEEE 802.11w is an unapproved draft and subject to change.) |
| * fixed Windows named pipes ctrl_iface to not stop listening for |
| commands if client program opens a named pipe and closes it |
| immediately without sending a command |
| * fixed USIM PIN status determination for the case that PIN is not |
| needed (this allows EAP-AKA to be used with USIM cards that do not |
| use PIN) |
| * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to |
| be used with cards that do not support file selection based on |
| partial AID |
| * added support for matching the subjectAltName of the authentication |
| server certificate against multiple name components (e.g., |
| altsubject_match="DNS:server.example.com;DNS:server2.example.com") |
| * fixed EAP-SIM/AKA key derivation for re-authentication case (only |
| affects IEEE 802.1X with dynamic WEP keys) |
| * changed ctrl_iface network configuration 'get' operations to not |
| return password/key material; if these fields are requested, "*" |
| will be returned if the password/key is set, but the value of the |
| parameter is not exposed |
| |
| 2006-08-27 - v0.5.5 |
| * added support for building Windows version with UNICODE defined |
| (wide-char functions) |
| * driver_ndis: fixed static WEP configuration to avoid race condition |
| issues with some NDIS drivers between association and setting WEP |
| keys |
| * driver_ndis: added validation for IELength value in scan results to |
| avoid crashes when using buggy NDIS drivers [Bug 165] |
| * fixed Release|Win32 target in the Visual Studio project files |
| (previously, only Debug|Win32 target was set properly) |
| * changed control interface API call wpa_ctrl_pending() to allow it to |
| return -1 on error (e.g., connection lost); control interface clients |
| will need to make sure that they verify that the value is indeed >0 |
| when determining whether there are pending messages |
| * added an alternative control interface backend for Windows targets: |
| Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default |
| control interface mechanism for Windows builds (previously, UDP to |
| localhost was used) |
| * changed ctrl_interface configuration for UNIX domain sockets: |
| - deprecated ctrl_interface_group variable (it may be removed in |
| future versions) |
| - allow both directory and group be configured with ctrl_interface |
| in following format: DIR=/var/run/wpa_supplicant GROUP=wheel |
| - ctrl_interface=/var/run/wpa_supplicant is still supported for the |
| case when group is not changed |
| * added support for controlling more than one interface per process in |
| Windows version |
| * added a workaround for a case where the AP is using unknown address |
| (e.g., MAC address of the wired interface) as the source address for |
| EAPOL-Key frames; previously, that source address was used as the |
| destination for EAPOL-Key frames and in key derivation; now, BSSID is |
| used even if the source address does not match with it |
| (this resolves an interoperability issue with Thomson SpeedTouch 580) |
| * added a workaround for UDP-based control interface (which was used in |
| Windows builds before this release) to prevent packets with forged |
| addresses from being accepted as local control requests |
| * removed ndis_events.cpp and possibility of using external |
| ndis_events.exe; C version (ndis_events.c) is fully functional and |
| there is no desire to maintain two separate versions of this |
| implementation |
| * ndis_events: Changed NDIS event notification design to use WMI to |
| learn the adapter description through Win32_PnPEntity class; this |
| should fix some cases where the adapter name was not recognized |
| correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500 |
| USB) [Bug 113] |
| * fixed selection of the first network in ap_scan=2 mode; previously, |
| wpa_supplicant could get stuck in SCANNING state when only the first |
| network for enabled (e.g., after 'wpa_cli select_network 0') |
| * winsvc: added support for configuring ctrl_interface parameters in |
| registry (ctrl_interface string value in |
| HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is |
| required to enable control interface (previously, this was hardcoded |
| to be enabled) |
| * allow wpa_gui subdirectory to be built with both Qt3 and Qt4 |
| * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format |
| |
| 2006-06-20 - v0.5.4 |
| * fixed build with CONFIG_STAKEY=y [Bug 143] |
| * added support for doing MLME (IEEE 802.11 management frame |
| processing) in wpa_supplicant when using Devicescape IEEE 802.11 |
| stack (wireless-dev.git tree) |
| * added a new network block configuration option, fragment_size, to |
| configure the maximum EAP fragment size |
| * driver_ndis: Disable WZC automatically for the selected interface to |
| avoid conflicts with two programs trying to control the radio; WZC |
| will be re-enabled (if it was enabled originally) when wpa_supplicant |
| is terminated |
| * added an experimental TLSv1 client implementation |
| (CONFIG_TLS=internal) that can be used instead of an external TLS |
| library, e.g., to reduce total size requirement on systems that do |
| not include any TLS library by default (this is not yet complete; |
| basic functionality is there, but certificate validation is not yet |
| included) |
| * added PeerKey handshake implementation for IEEE 802.11e |
| direct link setup (DLS) to replace STAKey handshake |
| * fixed WPA PSK update through ctrl_iface for the case where the old |
| PSK was derived from an ASCII passphrase and the new PSK is set as |
| a raw PSK (hex string) |
| * added new configuration option for identifying which network block |
| was used (id_str in wpa_supplicant.conf; included on |
| WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental |
| variable in wpa_cli action scripts; in addition WPA_ID variable is |
| set to the current unique identifier that wpa_supplicant assigned |
| automatically for the network and that can be used with |
| GET_NETWORK/SET_NETWORK ctrl_iface commands) |
| * wpa_cli action script is now called only when the connect/disconnect |
| status changes or when associating with a different network |
| * fixed configuration parser not to remove CCMP from group cipher list |
| if WPA-None (adhoc) is used (pairwise=NONE in that case) |
| * fixed integrated NDIS events processing not to hang the process due |
| to a missed change in eloop_win.c API in v0.5.3 [Bug 155] |
| * added support for EAP Generalized Pre-Shared Key (EAP-GPSK, |
| draft-clancy-emu-eap-shared-secret-00.txt) |
| * added Microsoft Visual Studio 2005 solution and project files for |
| build wpa_supplicant for Windows (see vs2005 subdirectory) |
| * eloop_win: fixed unregistration of Windows events |
| * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet |
| at the end of RSN pre-authentication and added unregistration of |
| a Windows event to avoid getting eloop_win stuck with an invalid |
| handle |
| * driver_ndis: added support for selecting AP based on BSSID |
| * added new environmental variable for wpa_cli action scripts: |
| WPA_CTRL_DIR is the current control interface directory |
| * driver_ndis: added support for using NDISUIO instead of WinPcap for |
| OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new |
| l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build |
| wpa_supplicant without requiring WinPcap; note that using NDISUIO |
| requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows |
| only one application to open the device |
| * changed NDIS driver naming to only include device GUID, e.g., |
| {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap |
| specific \Device\NPF_ prefix before the GUID; the prefix is still |
| allowed for backwards compatibility, but it is not required anymore |
| when specifying the interface |
| * driver_ndis: re-initialize driver interface is the adapter is removed |
| and re-inserted [Bug 159] |
| * driver_madwifi: fixed TKIP and CCMP sequence number configuration on |
| big endian hosts [Bug 146] |
| |
| 2006-04-27 - v0.5.3 |
| * fixed EAP-GTC response to include correct user identity when run as |
| phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2) |
| * driver_ndis: Fixed encryption mode configuration for unencrypted |
| networks (some NDIS drivers ignored this, but others, e.g., Broadcom, |
| refused to associate with open networks) [Bug 106] |
| * driver_ndis: use BSSID OID polling to detect when IBSS network is |
| formed even when ndis_events code is included since some NDIS drivers |
| do not generate media connect events in IBSS mode |
| * config_winreg: allow global ctrl_interface parameter to be configured |
| in Windows registry |
| * config_winreg: added support for saving configuration data into |
| Windows registry |
| * added support for controlling network device operational state |
| (dormant/up) for Linux 2.6.17 to improve DHCP processing (see |
| http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client |
| that can use this information) |
| * driver_wext: added support for WE-21 change to SSID configuration |
| * driver_wext: fixed privacy configuration for static WEP keys mode |
| [Bug 140] |
| * added an optional driver_ops callback for MLME-SETPROTECTION.request |
| primitive |
| * added support for EAP-SAKE (no EAP method number allocated yet, so |
| this is using the same experimental type 255 as EAP-PSK) |
| * added support for dynamically loading EAP methods (.so files) instead |
| of requiring them to be statically linked in; this is disabled by |
| default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information |
| on how to use this) |
| |
| 2006-03-19 - v0.5.2 |
| * do not try to use USIM APDUs when initializing PC/SC for SIM card |
| access for a network that has not enabled EAP-AKA |
| * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in |
| v0.5.1 due to the new support for expanded EAP types) |
| * added support for generating EAP Expanded Nak |
| * try to fetch scan results once before requesting new scan when |
| starting up in ap_scan=1 mode (this can speed up initial association |
| a lot with, e.g., madwifi-ng driver) |
| * added support for receiving EAPOL frames from a Linux bridge |
| interface (-bbr0 on command line) |
| * fixed EAPOL re-authentication for sessions that used PMKSA caching |
| * changed EAP method registration to use a dynamic list of methods |
| instead of a static list generated at build time |
| * fixed PMKSA cache deinitialization not to use freed memory when |
| removing PMKSA entries |
| * fixed a memory leak in EAP-TTLS re-authentication |
| * reject WPA/WPA2 message 3/4 if it does not include any valid |
| WPA/RSN IE |
| * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg |
| if the driver does not support SIOCSIWAUTH |
| |
| 2006-01-29 - v0.5.1 |
| * driver_test: added better support for multiple APs and STAs by using |
| a directory with sockets that include MAC address for each device in |
| the name (driver_param=test_dir=/tmp/test) |
| * added support for EAP expanded type (vendor specific EAP methods) |
| * added AP_SCAN command into ctrl_iface so that ap_scan configuration |
| option can be changed if needed |
| * wpa_cli/wpa_gui: skip non-socket files in control directory when |
| using UNIX domain sockets; this avoids selecting an incorrect |
| interface (e.g., a PID file could be in this directory, even though |
| use of this directory for something else than socket files is not |
| recommended) |
| * fixed TLS library deinitialization after RSN pre-authentication not |
| to disable TLS library for normal authentication |
| * driver_wext: Remove null-termination from SSID length if the driver |
| used it; some Linux drivers do this and they were causing problems in |
| wpa_supplicant not finding matching configuration block. This change |
| would break a case where the SSID actually ends in '\0', but that is |
| not likely to happen in real use. |
| * fixed PMKSA cache processing not to trigger deauthentication if the |
| current PMKSA cache entry is replaced with a valid new entry |
| * fixed PC/SC initialization for ap_scan != 1 modes (this fixes |
| EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or |
| ap_scan=2) |
| |
| 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases) |
| * added experimental STAKey handshake implementation for IEEE 802.11e |
| direct link setup (DLS); note: this is disabled by default in both |
| build and runtime configuration (can be enabled with CONFIG_STAKEY=y |
| and stakey=1) |
| * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to |
| decrypt AT_ENCR_DATA attributes correctly |
| * fixed EAP-AKA to allow resynchronization within the same session |
| * made code closer to ANSI C89 standard to make it easier to port to |
| other C libraries and compilers |
| * started moving operating system or C library specific functions into |
| wrapper functions defined in os.h and implemented in os_*.c to make |
| code more portable |
| * wpa_supplicant can now be built with Microsoft Visual C++ |
| (e.g., with the freely available Toolkit 2003 version or Visual |
| C++ 2005 Express Edition and Platform SDK); see nmake.mak for an |
| example makefile for nmake |
| * added support for using Windows registry for command line parameters |
| (CONFIG_MAIN=main_winsvc) and configuration data |
| (CONFIG_BACKEND=winreg); see win_example.reg for an example registry |
| contents; this version can be run both as a Windows service and as a |
| normal application; 'wpasvc.exe app' to start as applicant, |
| 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service, |
| 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to |
| unregister a service |
| * made it possible to link ndis_events.exe functionality into |
| wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED |
| * added better support for multiple control interface backends |
| (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported |
| * fixed PC/SC code to use correct length for GSM AUTH command buffer |
| and to not use pioRecvPci with SCardTransmit() calls; these were not |
| causing visible problems with pcsc-lite, but Windows Winscard.dll |
| refused the previously used parameters; this fixes EAP-SIM and |
| EAP-AKA authentication using SIM/USIM card under Windows |
| * added new event loop implementation for Windows using |
| WaitForMultipleObject() instead of select() in order to allow waiting |
| for non-socket objects; this can be selected with |
| CONFIG_ELOOP=eloop_win in .config |
| * added support for selecting l2_packet implementation in .config |
| (CONFIG_L2_PACKET; following options are available now: linux, pcap, |
| winpcap, freebsd, none) |
| * added new l2_packet implementation for WinPcap |
| (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to |
| reduce latency in EAPOL receive processing from about 100 ms to about |
| 3 ms |
| * added support for EAP-FAST key derivation using other ciphers than |
| RC4-128-SHA for authentication and AES128-SHA for provisioning |
| * added support for configuring CA certificate as DER file and as a |
| configuration blob |
| * fixed private key configuration as configuration blob and added |
| support for using PKCS#12 as a blob |
| * tls_gnutls: added support for using PKCS#12 files; added support for |
| session resumption |
| * added support for loading trusted CA certificates from Windows |
| certificate store: ca_cert="cert_store://<name>", where <name> is |
| likely CA (Intermediate CA certificates) or ROOT (root certificates) |
| * added C version of ndis_events.cpp and made it possible to build this |
| with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more |
| easily on cross-compilation builds |
| * added wpasvc.exe into Windows binary release; this is an alternative |
| version of wpa_supplicant.exe with configuration backend using |
| Windows registry and with the entry point designed to run as a |
| Windows service |
| * integrated ndis_events.exe functionality into wpa_supplicant.exe and |
| wpasvc.exe and removed this additional tool from the Windows binary |
| release since it is not needed anymore |
| * load winscard.dll functions dynamically when building with MinGW |
| since MinGW does not yet include winscard library |
| |
| 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases) |
| * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap |
| and WinPcap to receive frames sent to PAE group address |
| * disable EAP state machine when IEEE 802.1X authentication is not used |
| in order to get rid of bogus "EAP failed" messages |
| * fixed OpenSSL error reporting to go through all pending errors to |
| avoid confusing reports of old errors being reported at later point |
| during handshake |
| * fixed configuration file updating to not write empty variables |
| (e.g., proto or key_mgmt) that the file parser would not accept |
| * fixed ADD_NETWORK ctrl_iface command to use the same default values |
| for variables as empty network definitions read from config file |
| would get |
| * fixed EAP state machine to not discard EAP-Failure messages in many |
| cases (e.g., during TLS handshake) |
| * fixed a infinite loop in private key reading if the configured file |
| cannot be parsed successfully |
| * driver_madwifi: added support for madwifi-ng |
| * wpa_gui: do not display password/PSK field contents |
| * wpa_gui: added CA certificate configuration |
| * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID |
| * driver_ndis: include Beacon IEs in AssocInfo in order to notice if |
| the new AP is using different WPA/RSN IE |
| * use longer timeout for IEEE 802.11 association to avoid problems with |
| drivers that may take more than five second to associate |
| |
| 2005-10-27 - v0.4.6 |
| * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in |
| RSN IE, but WPA IE would match with wpa_supplicant configuration |
| * added support for named configuration blobs in order to avoid having |
| to use file system for external files (e.g., certificates); |
| variables can be set to "blob://<blob name>" instead of file path to |
| use a named blob; supported fields: pac_file, client_cert, |
| private_key |
| * fixed RSN pre-authentication (it was broken in the clean up of WPA |
| state machine interface in v0.4.5) |
| * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make |
| sure the driver configures broadcast decryption correctly |
| * added ca_path (and ca_path2) configuration variables that can be used |
| to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the |
| system-wide trusted CA list |
| * added support for starting wpa_supplicant without a configuration |
| file (-C argument must be used to set ctrl_interface parameter for |
| this case; in addition, -p argument can be used to provide |
| driver_param; these new arguments can also be used with a |
| configuration to override the values from the configuration) |
| * added global control interface that can be optionally used for adding |
| and removing network interfaces dynamically (-g command line argument |
| for both wpa_supplicant and wpa_cli) without having to restart |
| wpa_supplicant process |
| * wpa_gui: |
| - try to save configuration whenever something is modified |
| - added WEP key configuration |
| - added possibility to edit the current network configuration |
| * driver_ndis: fixed driver polling not to increase frequency on each |
| received EAPOL frame due to incorrectly cancelled timeout |
| * added simple configuration file examples (in examples subdirectory) |
| * fixed driver_wext.c to filter wireless events based on ifindex to |
| avoid interfaces receiving events from other interfaces |
| * delay sending initial EAPOL-Start couple of seconds to speed up |
| authentication for the most common case of Authenticator starting |
| EAP authentication immediately after association |
| |
| 2005-09-25 - v0.4.5 |
| * added a workaround for clearing keys with ndiswrapper to allow |
| roaming from WPA enabled AP to plaintext one |
| * added docbook documentation (doc/docbook) that can be used to |
| generate, e.g., man pages |
| * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for |
| PF_PACKET in order to prepare for network devices that do not use |
| Ethernet headers (e.g., network stack with native IEEE 802.11 frames) |
| * use receipt of EAPOL-Key frame as a lower layer success indication |
| for EAP state machine to allow recovery from dropped EAP-Success |
| frame |
| * cleaned up internal EAPOL frame processing by not including link |
| layer (Ethernet) header during WPA and EAPOL/EAP processing; this |
| header is added only when transmitted the frame; this makes it easier |
| to use wpa_supplicant on link layers that use different header than |
| Ethernet |
| * updated EAP-PSK to use draft 9 by default since this can now be |
| tested with hostapd; removed support for draft 3, including |
| server_nai configuration option from network blocks |
| * driver_wired: add PAE address to the multicast address list in order |
| to be able to receive EAPOL frames with drivers that do not include |
| these multicast addresses by default |
| * driver_wext: add support for WE-19 |
| * added support for multiple configuration backends (CONFIG_BACKEND |
| option); currently, only 'file' is supported (i.e., the format used |
| in wpa_supplicant.conf) |
| * added support for updating configuration ('wpa_cli save_config'); |
| this is disabled by default and can be enabled with global |
| update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli |
| and wpa_gui to store the configuration changes in a permanent store |
| * added GET_NETWORK ctrl_iface command |
| (e.g., 'wpa_cli get_network 0 ssid') |
| |
| 2005-08-21 - v0.4.4 |
| * replaced OpenSSL patch for EAP-FAST support |
| (openssl-tls-extensions.patch) with a more generic and correct |
| patch (the new patch is not compatible with the previous one, so the |
| OpenSSL library will need to be patched with the new patch in order |
| to be able to build wpa_supplicant with EAP-FAST support) |
| * added support for using Windows certificate store (through CryptoAPI) |
| for client certificate and private key operations (EAP-TLS) |
| (see wpa_supplicant.conf for more information on how to configure |
| this with private_key) |
| * ported wpa_gui to Windows |
| * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be |
| built with the open source version of the Qt4 for Windows |
| * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used |
| with drivers that do not support WPA |
| * ndis_events: fixed Windows 2000 support |
| * added support for enabling/disabling networks from the list of all |
| configured networks ('wpa_cli enable_network <network id>' and |
| 'wpa_cli disable_network <network id>') |
| * added support for adding and removing network from the current |
| configuration ('wpa_cli add_network' and 'wpa_cli remove_network |
| <network id>'); added networks are disabled by default and they can |
| be enabled with enable_network command once the configuration is done |
| for the new network; note: configuration file is not yet updated, so |
| these new networks are lost when wpa_supplicant is restarted |
| * added support for setting network configuration parameters through |
| the control interface, for example: |
| wpa_cli set_network 0 ssid "\"my network\"" |
| * fixed parsing of strings that include both " and # within double |
| quoted area (e.g., "start"#end") |
| * added EAP workaround for PEAP session resumption: allow outer, |
| i.e., not tunneled, EAP-Success to terminate session since; this can |
| be disabled with eap_workaround=0 |
| (this was allowed for PEAPv1 before, but now it is also allowed for |
| PEAPv0 since at least one RADIUS authentication server seems to be |
| doing this for PEAPv0, too) |
| * wpa_gui: added preliminary support for adding new networks to the |
| wpa_supplicant configuration (double click on the scan results to |
| open network configuration) |
| |
| 2005-06-26 - v0.4.3 |
| * removed interface for external EAPOL/EAP supplicant (e.g., |
| Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required |
| anymore and is unlikely to be used by anyone |
| * driver_ndis: fixed WinPcap 3.0 support |
| * fixed build with CONFIG_DNET_PCAP=y on Linux |
| * l2_packet: moved different implementations into separate files |
| (l2_packet_*.c) |
| |
| 2005-06-12 - v0.4.2 |
| * driver_ipw: updated driver structures to match with ipw2200-1.0.4 |
| (note: ipw2100-1.1.0 is likely to require an update to work with |
| this) |
| * added support for using ap_scan=2 mode with multiple network blocks; |
| wpa_supplicant will go through the networks one by one until the |
| driver reports a successful association; this uses the same order for |
| networks as scan_ssid=1 scans, i.e., the priority field is ignored |
| and the network block order in the file is used instead |
| * fixed a potential issue in RSN pre-authentication ending up using |
| freed memory if pre-authentication times out |
| * added support for matching alternative subject name extensions of the |
| authentication server certificate; new configuration variables |
| altsubject_match and altsubject_match2 |
| * driver_ndis: added support for IEEE 802.1X authentication with wired |
| NDIS drivers |
| * added support for querying private key password (EAP-TLS) through the |
| control interface (wpa_cli/wpa_gui) if one is not included in the |
| configuration file |
| * driver_broadcom: fixed couple of memory leaks in scan result |
| processing |
| * EAP-PAX is now registered as EAP type 46 |
| * fixed EAP-PAX MAC calculation |
| * fixed EAP-PAX CK and ICK key derivation |
| * added support for using password with EAP-PAX (as an alternative to |
| entering key with eappsk); SHA-1 hash of the password will be used as |
| the key in this case |
| * added support for arbitrary driver interface parameters through the |
| configuration file with a new driver_param field; this adds a new |
| driver_ops function set_param() |
| * added possibility to override l2_packet module with driver interface |
| API (new send_eapol handler); this can be used to implement driver |
| specific TX/RX functions for EAPOL frames |
| * fixed ctrl_interface_group processing for the case where gid is |
| entered as a number, not group name |
| * driver_test: added support for testing hostapd with wpa_supplicant |
| by using test driver interface without any kernel drivers or network |
| cards |
| |
| 2005-05-22 - v0.4.1 |
| * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL |
| packets to be encrypted; this was apparently broken by the changed |
| ioctl order in v0.4.0 |
| * driver_madwifi: added preliminary support for compiling against 'BSD' |
| branch of madwifi CVS tree |
| * added support for EAP-MSCHAPv2 password retries within the same EAP |
| authentication session |
| * added support for password changes with EAP-MSCHAPv2 (used when the |
| password has expired) |
| * added support for reading additional certificates from PKCS#12 files |
| and adding them to the certificate chain |
| * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys |
| were used |
| * fixed a possible double free in EAP-TTLS fast-reauthentication when |
| identity or password is entered through control interface |
| * display EAP Notification messages to user through control interface |
| with "CTRL-EVENT-EAP-NOTIFICATION" prefix |
| * added GUI version of wpa_cli, wpa_gui; this is not build |
| automatically with 'make'; use 'make wpa_gui' to build (this requires |
| Qt development tools) |
| * added 'disconnect' command to control interface for setting |
| wpa_supplicant in state where it will not associate before |
| 'reassociate' command has been used |
| * added support for selecting a network from the list of all configured |
| networks ('wpa_cli select_network <network id>'; this disabled all |
| other networks; to re-enable, 'wpa_cli select_network any') |
| * added support for getting scan results through control interface |
| * added EAP workaround for PEAPv1 session resumption: allow outer, |
| i.e., not tunneled, EAP-Success to terminate session since; this can |
| be disabled with eap_workaround=0 |
| |
| 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases) |
| * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be |
| used to reduce the size of the wpa_supplicant considerably if |
| debugging code is not needed |
| * fixed EAPOL-Key validation to drop packets with invalid Key Data |
| Length; such frames could have crashed wpa_supplicant due to buffer |
| overflow |
| * added support for wired authentication (IEEE 802.1X on wired |
| Ethernet); driver interface 'wired' |
| * obsoleted set_wpa() handler in the driver interface API (it can be |
| replaced by moving enable/disable functionality into init()/deinit()) |
| (calls to set_wpa() are still present for backwards compatibility, |
| but they may be removed in the future) |
| * driver_madwifi: fixed association in plaintext mode |
| * modified the EAP workaround that accepts EAP-Success with incorrect |
| Identifier to be even less strict about verification in order to |
| interoperate with some authentication servers |
| * added support for sending TLS alerts |
| * added support for 'any' SSID wildcard; if ssid is not configured or |
| is set to an empty string, any SSID will be accepted for non-WPA AP |
| * added support for asking PIN (for SIM) from frontends (e.g., |
| wpa_cli); if a PIN is needed, but not included in the configuration |
| file, a control interface request is sent and EAP processing is |
| delayed until the PIN is available |
| * added support for using external devices (e.g., a smartcard) for |
| private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config); |
| new wpa_supplicant.conf variables: |
| - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path |
| - network: engine, engine_id, key_id |
| * added experimental support for EAP-PAX |
| * added monitor mode for wpa_cli (-a<path to a program to run>) that |
| allows external commands (e.g., shell scripts) to be run based on |
| wpa_supplicant events, e.g., when authentication has been completed |
| and data connection is ready; other related wpa_cli arguments: |
| -B (run in background), -P (write PID file); wpa_supplicant has a new |
| command line argument (-W) that can be used to make it wait until a |
| control interface command is received in order to avoid missing |
| events |
| * added support for opportunistic WPA2 PMKSA key caching (disabled by |
| default, can be enabled with proactive_key_caching=1) |
| * fixed RSN IE in 4-Way Handshake message 2/4 for the case where |
| Authenticator rejects PMKSA caching attempt and the driver is not |
| using assoc_info events |
| * added -P<pid file> argument for wpa_supplicant to write the current |
| process id into a file |
| |
| 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases) |
| * added new phase1 option parameter, include_tls_length=1, to force |
| wpa_supplicant to add TLS Message Length field to all TLS messages |
| even if the packet is not fragmented; this may be needed with some |
| authentication servers |
| * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when |
| using drivers that take care of AP selection (e.g., when using |
| ap_scan=2) |
| * fixed reprocessing of pending request after ctrl_iface requests for |
| identity/password/otp |
| * fixed ctrl_iface requests for identity/password/otp in Phase 2 of |
| EAP-PEAP and EAP-TTLS |
| * all drivers using driver_wext: set interface up and select Managed |
| mode when starting wpa_supplicant; set interface down when exiting |
| * renamed driver_ipw2100.c to driver_ipw.c since it now supports both |
| ipw2100 and ipw2200; please note that this also changed the |
| configuration variable in .config to CONFIG_DRIVER_IPW |
| |
| 2005-01-24 - v0.3.6 |
| * fixed a busy loop introduced in v0.3.5 for scan result processing |
| when no matching AP is found |
| |
| 2005-01-23 - v0.3.5 |
| * added a workaround for an interoperability issue with a Cisco AP |
| when using WPA2-PSK |
| * fixed non-WPA IEEE 802.1X to use the same authentication timeout as |
| WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow |
| retransmission of dropped frames) |
| * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version |
| (e.g., segfault when processing EAPOL-Key frames) |
| * fixed EAP workaround and fast reauthentication configuration for |
| RSN pre-authentication; previously these were disabled and |
| pre-authentication would fail if the used authentication server |
| requires EAP workarounds |
| * added support for blacklisting APs that fail or timeout |
| authentication in ap_scan=1 mode so that all APs are tried in cases |
| where the ones with strongest signal level are failing authentication |
| * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS |
| authentication attempt |
| * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded |
| in the previous authentication (previously, only Phase 1 success was |
| verified) |
| |
| 2005-01-09 - v0.3.4 |
| * added preliminary support for IBSS (ad-hoc) mode configuration |
| (mode=1 in network block); this included a new key_mgmt mode |
| WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no |
| key management; see wpa_supplicant.conf for more details and an |
| example on how to configure this (note: this is currently implemented |
| only for driver_hostapd.c, but the changes should be trivial to add |
| in associate() handler for other drivers, too (assuming the driver |
| supports WPA-None) |
| * added preliminary port for native Windows (i.e., no cygwin) using |
| mingw |
| |
| 2005-01-02 - v0.3.3 |
| * added optional support for GNU Readline and History Libraries for |
| wpa_cli (CONFIG_READLINE) |
| * cleaned up EAP state machine <-> method interface and number of |
| small problems with error case processing not terminating on |
| EAP-Failure but waiting for timeout |
| * added couple of workarounds for interoperability issues with a |
| Cisco AP when using WPA2 |
| * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt); |
| Note: This requires a patch for openssl to add support for TLS |
| extensions and number of workarounds for operations without |
| certificates. Proof of concept type of experimental patch is |
| included in openssl-tls-extensions.patch. |
| |
| 2004-12-19 - v0.3.2 |
| * fixed private key loading for cases where passphrase is not set |
| * fixed Windows/cygwin L2 packet handler freeing; previous version |
| could cause a segfault when RSN pre-authentication was completed |
| * added support for PMKSA caching with drivers that generate RSN IEs |
| (e.g., NDIS); currently, this is only implemented in driver_ndis.c, |
| but similar code can be easily added to driver_ndiswrapper.c once |
| ndiswrapper gets full support for RSN PMKSA caching |
| * improved recovery from PMKID mismatches by requesting full EAP |
| authentication in case of failed PMKSA caching attempt |
| * driver_ndis: added support for NDIS NdisMIncidateStatus() events |
| (this requires that ndis_events is ran while wpa_supplicant is |
| running) |
| * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys |
| * added support for driver interfaces to replace the interface name |
| based on driver/OS specific mapping, e.g., in case of driver_ndis, |
| this allows the beginning of the adapter description to be used as |
| the interface name |
| * added support for CR+LF (Windows-style) line ends in configuration |
| file |
| * driver_ndis: enable radio before starting scanning, disable radio |
| when exiting |
| * modified association event handler to set portEnabled = FALSE before |
| clearing port Valid in order to reset EAP state machine and avoid |
| problems with new authentication getting ignored because of state |
| machines ending up in AUTHENTICATED/SUCCESS state based on old |
| information |
| * added support for driver events to add PMKID candidates in order to |
| allow drivers to give priority to most likely roaming candidates |
| * driver_hostap: moved PrivacyInvoked configuration to associate() |
| function so that this will not be set for plaintext connections |
| * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver |
| interface can distinguish plaintext and IEEE 802.1X (no WPA) |
| authentication |
| * fixed static WEP key configuration to use broadcast/default type for |
| all keys (previously, the default TX key was configured as pairwise/ |
| unicast key) |
| * driver_ndis: added legacy WPA capability detection for non-WPA2 |
| drivers |
| * added support for setting static WEP keys for IEEE 802.1X without |
| dynamic WEP keying (eapol_flags=0) |
| |
| 2004-12-12 - v0.3.1 |
| * added support for reading PKCS#12 (PFX) files (as a replacement for |
| PEM/DER) to get certificate and private key (CONFIG_PKCS12) |
| * fixed compilation with CONFIG_PCSC=y |
| * added new ap_scan mode, ap_scan=2, for drivers that take care of |
| association, but need to be configured with security policy and SSID, |
| e.g., ndiswrapper and NDIS driver; this mode should allow such |
| drivers to work with hidden SSIDs and optimized roaming; when |
| ap_scan=2 is used, only the first network block in the configuration |
| file is used and this configuration should have explicit security |
| policy (i.e., only one option in the lists) for key_mgmt, pairwise, |
| group, proto variables |
| * added experimental port of wpa_supplicant for Windows |
| - driver_ndis.c driver interface (NDIS OIDs) |
| - currently, this requires cygwin and WinPcap |
| - small utility, win_if_list, can be used to get interface name |
| * control interface can now be removed at build time; add |
| CONFIG_CTRL_IFACE=y to .config to maintain old functionality |
| * optional Xsupplicant interface can now be removed at build time; |
| (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back) |
| * added auth_alg to driver interface associate() parameters to make it |
| easier for drivers to configure authentication algorithm as part of |
| the association |
| |
| 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases) |
| * driver_broadcom: added new driver interface for Broadcom wl.o driver |
| (a generic driver for Broadcom IEEE 802.11a/g cards) |
| * wpa_cli: fixed parsing of -p <path> command line argument |
| * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS |
| ACK, not tunneled EAP-Success (of which only the first byte was |
| actually send due to a bug in previous code); this seems to |
| interoperate with most RADIUS servers that implements PEAPv1 |
| * PEAPv1: added support for terminating PEAP authentication on tunneled |
| EAP-Success message; this can be configured by adding |
| peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf |
| (some RADIUS servers require this whereas others require a tunneled |
| reply |
| * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to |
| the old label for key derivation; previously, the default was 1, |
| but it looks like most existing PEAPv1 implementations use the old |
| label which is thus more suitable default option |
| * added support for EAP-PSK (draft-bersani-eap-psk-03.txt) |
| * fixed parsing of wep_tx_keyidx |
| * added support for configuring list of allowed Phase 2 EAP types |
| (for both EAP-PEAP and EAP-TTLS) instead of only one type |
| * added support for configuring IEEE 802.11 authentication algorithm |
| (auth_alg; mainly for using Shared Key authentication with static |
| WEP keys) |
| * added support for EAP-AKA (with UMTS SIM) |
| * fixed couple of errors in PCSC handling that could have caused |
| random-looking errors for EAP-SIM |
| * added support for EAP-SIM pseudonyms and fast re-authentication |
| * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS |
| session resumption) |
| * added support for EAP-SIM with two challanges |
| (phase1="sim_min_num_chal=3" can be used to require three challenges) |
| * added support for configuring DH/DSA parameters for an ephemeral DH |
| key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters |
| dh_file and dh_file2 (phase 2); this adds support for using DSA keys |
| and optional DH key exchange to achieve forward secracy with RSA keys |
| * added support for matching subject of the authentication server |
| certificate with a substring when using EAP-TLS/PEAP/TTLS; new |
| configuration variables subject_match and subject_match2 |
| * changed SSID configuration in driver_wext.c (used by many driver |
| interfaces) to use ssid_len+1 as the length for SSID since some Linux |
| drivers expect this |
| * fixed couple of unaligned reads in scan result parsing to fix WPA |
| connection on some platforms (e.g., ARM) |
| * added driver interface for Intel ipw2100 driver |
| * added support for LEAP with WPA |
| * added support for larger scan results report (old limit was 4 kB of |
| data, i.e., about 35 or so APs) when using Linux wireless extensions |
| v17 or newer |
| * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start |
| only if there is a PMKSA cache entry for the current AP |
| * fixed error handling for case where reading of scan results fails: |
| must schedule a new scan or wpa_supplicant will remain waiting |
| forever |
| * changed debug output to remove shared password/key material by |
| default; all key information can be included with -K command line |
| argument to match the previous behavior |
| * added support for timestamping debug log messages (disabled by |
| default, can be enabled with -t command line argument) |
| * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104 |
| if keys are not configured to be used; this fixes IEEE 802.1X mode |
| with drivers that use this information to configure whether Privacy |
| bit can be in Beacon frames (e.g., ndiswrapper) |
| * avoid clearing driver keys if no keys have been configured since last |
| key clear request; this seems to improve reliability of group key |
| handshake for ndiswrapper & NDIS driver which seems to be suffering |
| of some kind of timing issue when the keys are cleared again after |
| association |
| * changed driver interface API: |
| - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which |
| version is being used (now, this is set to 2; previously, it was |
| not defined) |
| - pass pointer to private data structure to all calls |
| - the new API is not backwards compatible; all in-tree driver |
| interfaces has been converted to the new API |
| * added support for controlling multiple interfaces (radios) per |
| wpa_supplicant process; each interface needs to be listed on the |
| command line (-c, -i, -D arguments) with -N as a separator |
| (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi) |
| * added a workaround for EAP servers that incorrectly use same Id for |
| sequential EAP packets |
| * changed libpcap/libdnet configuration to use .config variable, |
| CONFIG_DNET_PCAP, instead of requiring Makefile modification |
| * improved downgrade attack detection in IE verification of msg 3/4: |
| verify both WPA and RSN IEs, if present, not only the selected one; |
| reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or |
| Probe Response frame, and RSN is enabled in wpa_supplicant |
| configuration |
| * fixed WPA msg 3/4 processing to allow Key Data field contain other |
| IEs than just one WPA IE |
| * added support for FreeBSD and driver interface for the BSD net80211 |
| layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the |
| required kernel mods have not yet been committed |
| * made EAP workarounds configurable; enabled by default, can be |
| disabled with network block option eap_workaround=0 |
| |
| 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases) |
| * resolved couple of interoperability issues with EAP-PEAPv1 and |
| Phase 2 (inner EAP) fragment reassembly |
| * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the |
| AP is using non-zero key index for the unicast key and key index zero |
| for the broadcast key |
| * driver_hostap: fixed IEEE 802.1X WEP key updates and |
| re-authentication by allowing unencrypted EAPOL frames when not using |
| WPA |
| * added a new driver interface, 'wext', which uses only standard, |
| driver independent functionality in Linux wireless extensions; |
| currently, this can be used only for non-WPA IEEE 802.1X mode, but |
| eventually, this is to be extended to support full WPA/WPA2 once |
| Linux wireless extensions get support for this |
| * added support for mode in which the driver is responsible for AP |
| scanning and selection; this is disabled by default and can be |
| enabled with global ap_scan=0 variable in wpa_supplicant.conf; |
| this mode can be used, e.g., with generic 'wext' driver interface to |
| use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver |
| supporting wireless extensions. |
| * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g., |
| operation with an AP that does not include SSID in the Beacon frames) |
| * added support for new EAP authentication methods: |
| EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP |
| * added support for asking one-time-passwords from frontends (e.g., |
| wpa_cli); this 'otp' command works otherwise like 'password' command, |
| but the password is used only once and the frontend will be asked for |
| a new password whenever a request from authenticator requires a |
| password; this can be used with both EAP-OTP and EAP-GTC |
| * changed wpa_cli to automatically re-establish connection so that it |
| does not need to be re-started when wpa_supplicant is terminated and |
| started again |
| * improved user data (identity/password/otp) requests through |
| frontends: process pending EAPOL packets after getting new |
| information so that full authentication does not need to be |
| restarted; in addition, send pending requests again whenever a new |
| frontend is attached |
| * changed control frontends to use a new directory for socket files to |
| make it easier for wpa_cli to automatically select between interfaces |
| and to provide access control for the control interface; |
| wpa_supplicant.conf: ctrl_interface is now a path |
| (/var/run/wpa_supplicant is the recommended path) and |
| ctrl_interface_group can be used to select which group gets access to |
| the control interface; |
| wpa_cli: by default, try to connect to the first interface available |
| in /var/run/wpa_supplicant; this path can be overriden with -p option |
| and an interface can be selected with -i option (i.e., in most common |
| cases, wpa_cli does not need to get any arguments) |
| * added support for LEAP |
| * added driver interface for Linux ndiswrapper |
| * added priority option for network blocks in the configuration file; |
| this allows networks to be grouped based on priority (the scan |
| results are searched for matches with network blocks in this order) |
| |
| 2004-06-20 - v0.2.3 |
| * sort scan results to improve AP selection |
| * fixed control interface socket removal for some error cases |
| * improved scan requesting and authentication timeout |
| * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and |
| TLS processing |
| * PEAP version can now be forced with phase1="peapver=<ver>" |
| (mostly for testing; by default, the highest version supported by |
| both the Supplicant and Authentication Server is selected |
| automatically) |
| * added support for madwifi driver (Atheros ar521x) |
| * added a workaround for cases where AP sets Install Tx/Rx bit for |
| WPA Group Key messages when pairwise keys are used (without this, |
| the Group Key would be used for Tx and the AP would drop frames |
| from the station) |
| * added GSM SIM/USIM interface for GSM authentication algorithm for |
| EAP-SIM; this requires pcsc-lite |
| * added support for ATMEL AT76C5XXx driver |
| * fixed IEEE 802.1X WEP key derivation in the case where Authenticator |
| does not include key data in the EAPOL-Key frame (i.e., part of |
| EAP keying material is used as data encryption key) |
| * added support for using plaintext and static WEP networks |
| (key_mgmt=NONE) |
| |
| 2004-05-31 - v0.2.2 |
| * added support for new EAP authentication methods: |
| EAP-TTLS/EAP-MD5-Challenge |
| EAP-TTLS/EAP-GTC |
| EAP-TTLS/EAP-MSCHAPv2 |
| EAP-TTLS/EAP-TLS |
| EAP-TTLS/MSCHAPv2 |
| EAP-TTLS/MSCHAP |
| EAP-TTLS/PAP |
| EAP-TTLS/CHAP |
| EAP-PEAP/TLS |
| EAP-PEAP/GTC |
| EAP-PEAP/MD5-Challenge |
| EAP-GTC |
| EAP-SIM (not yet complete; needs GSM/SIM authentication interface) |
| * added support for anonymous identity (to be used when identity is |
| sent in plaintext; real identity will be used within TLS protected |
| tunnel (e.g., with EAP-TTLS) |
| * added event messages from wpa_supplicant to frontends, e.g., wpa_cli |
| * added support for requesting identity and password information using |
| control interface; in other words, the password for EAP-PEAP or |
| EAP-TTLS does not need to be included in the configuration file since |
| a frontand (e.g., wpa_cli) can ask it from the user |
| * improved RSN pre-authentication to use a candidate list and process |
| all candidates from each scan; not only one per scan |
| * fixed RSN IE and WPA IE capabilities field parsing |
| * ignore Tx bit in GTK IE when Pairwise keys are used |
| * avoid making new scan requests during IEEE 802.1X negotiation |
| * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant |
| with TLS support (this replaces the included implementation with |
| library code to save about 8 kB since the library code is needed |
| anyway for TLS) |
| * fixed WPA-PSK only mode when compiled without IEEE 802.1X support |
| (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config) |
| |
| 2004-05-06 - v0.2.1 |
| * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1) |
| Supplicant |
| - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1] |
| - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf] |
| - EAP-MD5 (cannot be used with WPA-RADIUS) |
| [draft-ietf-eap-rfc2284bis-09.txt] |
| - EAP-TLS [RFC 2716] |
| - EAP-MSCHAPv2 (currently used only with EAP-PEAP) |
| - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt] |
| [draft-kamath-pppext-eap-mschapv2-00.txt] |
| (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by |
| default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey) |
| - new configuration file options: eap, identity, password, ca_cert, |
| client_cert, privatekey, private_key_passwd |
| - Xsupplicant is not required anymore, but it can be used by |
| disabling the internal IEEE 802.1X Supplicant with -e command line |
| option |
| - this code is not included in the default build; Makefile need to |
| be edited for this (uncomment lines for selected functionality) |
| - EAP-TLS and EAP-PEAP require openssl libraries |
| * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..) |
| * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys |
| (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X |
| EAPOL-Key frames instead of WPA key handshakes) |
| * added support for IEEE 802.11i/RSN (WPA2) |
| - improved PTK Key Handshake |
| - PMKSA caching, pre-authentication |
| * fixed wpa_supplicant to ignore possible extra data after WPA |
| EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using |
| TPTK' error from message 3 of 4-Way Handshake in case the AP |
| includes extra data after the EAPOL-Key) |
| * added interface for external programs (frontends) to control |
| wpa_supplicant |
| - CLI example (wpa_cli) with interactive mode and command line |
| mode |
| - replaced SIGUSR1 status/statistics with the new control interface |
| * made some feature compile time configurable |
| - .config file for make |
| - driver interfaces (hostap, hermes, ..) |
| - EAPOL/EAP functions |
| |
| 2004-02-15 - v0.2.0 |
| * Initial version of wpa_supplicant |
