1 ChangeLog for wpa_supplicant 2 3 2012-05-10 - v1.0 4 * bsd: Add support for setting HT values in IFM_MMASK. 5 * Delay STA entry removal until Deauth/Disassoc TX status in AP mode. 6 This allows the driver to use PS buffering of Deauthentication and 7 Disassociation frames when the STA is in power save sleep. Only 8 available with drivers that provide TX status events for Deauth/ 9 Disassoc frames (nl80211). 10 * Drop oldest unknown BSS table entries first. This makes it less 11 likely to hit connection issues in environments with huge number 12 of visible APs. 13 * Add systemd support. 14 * Add support for setting the syslog facility from the config file 15 at build time. 16 * atheros: Add support for IEEE 802.11w configuration. 17 * AP mode: Allow enable HT20 if driver supports it, by setting the 18 config parameter ieee80211n. 19 * Allow AP mode to disconnect STAs based on low ACK condition (when 20 the data connection is not working properly, e.g., due to the STA 21 going outside the range of the AP). Disabled by default, enable by 22 config option disassoc_low_ack. 23 * nl80211: 24 - Support GTK rekey offload. 25 - Support PMKSA candidate events. This adds support for RSN 26 pre-authentication with nl80211 interface and drivers that handle 27 roaming internally. 28 * dbus: 29 - Add a DBus signal for EAP SM requests, emitted on the Interface 30 object. 31 - Export max scan ssids supported by the driver as MaxScanSSID. 32 - Add signal Certification for information about server certification. 33 - Add BSSExpireAge and BSSExpireCount interface properties and 34 support set/get, which allows for setting BSS cache expiration age 35 and expiration scan count. 36 - Add ConfigFile to AddInterface properties. 37 - Add Interface.Country property and support to get/set the value. 38 - Add DBus property CurrentAuthMode. 39 - P2P DBus API added. 40 - Emit property changed events (for property BSSs) when adding/ 41 removing BSSs. 42 - Treat '' in SSIDs of Interface.Scan as a request for broadcast 43 scan, instead of ignoring it. 44 - Add DBus getter/setter for FastReauth. 45 - Raise PropertiesChanged on org.freedesktop.DBus.Properties. 46 * wpa_cli: 47 - Send AP-STA-DISCONNECTED event when an AP disconnects a station 48 due to inactivity. 49 - Make second argument to set command optional. This can be used to 50 indicate a zero length value. 51 - Add signal_poll command. 52 - Add bss_expire_age and bss_expire_count commands to set/get BSS 53 cache expiration age and expiration scan count. 54 - Add ability to set scan interval (the time in seconds wpa_s waits 55 before requesting a new scan after failing to find a suitable 56 network in scan results) using scan_interval command. 57 - Add event CTRL-EVENT-ASSOC-REJECT for association rejected. 58 - Add command get version, that returns wpa_supplicant version string. 59 - Add command sta_autoconnect for disabling automatic reconnection 60 on receiving disconnection event. 61 - Setting bssid parameter to an empty string "" or any can now be 62 used to clear the bssid_set flag in a network block, i.e., to remove 63 bssid filtering. 64 - Add tdls_testing command to add a special testing feature for 65 changing TDLS behavior. Build param CONFIG_TDLS_TESTING must be 66 enabled as well. 67 - For interworking, add wpa_cli commands interworking_select, 68 interworking_connect, anqp_get, fetch_anqp, and stop_fetch_anqp. 69 - Many P2P commands were added. See README-P2P. 70 - Many WPS/WPS ER commands - see WPS/WPS ER sections for details. 71 - Allow set command to change global config parameters. 72 - Add log_level command, which can be used to display the current 73 debugging level and to change the log level during run time. 74 - Add note command, which can be used to insert notes to the debug 75 log. 76 - Add internal line edit implementation. CONFIG_WPA_CLI_EDIT=y 77 can now be used to build wpa_cli with internal implementation of 78 line editing and history support. This can be used as a replacement 79 for CONFIG_READLINE=y. 80 * AP mode: Add max_num_sta config option, which can be used to limit 81 the number of stations allowed to connect to the AP. 82 * Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad 83 config file. 84 * wext: Increase scan timeout from 5 to 10 seconds. 85 * Add blacklist command, allowing an external program to 86 manage the BSS blacklist and display its current contents. 87 * WPS: 88 - Add wpa_cli wps_pin get command for generating random PINs. This can 89 be used in a UI to generate a PIN without starting WPS (or P2P) 90 operation. 91 - Set RF bands based on driver capabilities, instead of hardcoding 92 them. 93 - Add mechanism for indicating non-standard WPS errors. 94 - Add CONFIG_WPS_REG_DISABLE_OPEN=y option to disable open networks 95 by default. 96 - Add wps_ap_pin cli command for wpa_supplicant AP mode. 97 - Add wps_check_pin cli command for processing PIN from user input. 98 UIs can use this command to process a PIN entered by a user and to 99 validate the checksum digit (if present). 100 - Cancel WPS operation on PBC session overlap detection. 101 - New wps_cancel command in wpa_cli will cancel a pending WPS 102 operation. 103 - wpa_cli action: Add WPS_EVENT_SUCCESS and WPS_EVENT_FAIL handlers. 104 - Trigger WPS config update on Manufacturer, Model Name, Model 105 Number, and Serial Number changes. 106 - Fragment size is now configurable for EAP-WSC peer. Use 107 wpa_cli set wps_fragment_size <val>. 108 - Disable AP PIN after 10 consecutive failures. Slow down attacks on 109 failures up to 10. 110 - Allow AP to start in Enrollee mode without AP PIN for probing, to 111 be compatible with Windows 7. 112 - Add Config Error into WPS-FAIL events to provide more info to the 113 user on how to resolve the issue. 114 - Label and Display config methods are not allowed to be enabled 115 at the same time, since it is unclear which PIN to use if both 116 methods are advertised. 117 - When controlling multiple interfaces: 118 - apply WPS commands to all interfaces configured to use WPS 119 - apply WPS config changes to all interfaces that use WPS 120 - when an attack is detected on any interface, disable AP PIN on 121 all interfaces 122 * WPS ER: 123 - Add special AP Setup Locked mode to allow read only ER. 124 ap_setup_locked=2 can now be used to enable a special mode where 125 WPS ER can learn the current AP settings, but cannot change them. 126 - Show SetSelectedRegistrar events as ctrl_iface events 127 - Add wps_er_set_config to enroll a network based on a local 128 network configuration block instead of having to (re-)learn the 129 current AP settings with wps_er_learn. 130 - Allow AP filtering based on IP address, add ctrl_iface event for 131 learned AP settings, add wps_er_config command to configure an AP. 132 * WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2) 133 - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool 134 for testing protocol extensibility. 135 - Add build option CONFIG_WPS_STRICT to allow disabling of WPS 136 workarounds. 137 - Add support for AuthorizedMACs attribute. 138 * TDLS: 139 - Propogate TDLS related nl80211 capability flags from kernel and 140 add them as driver capability flags. If the driver doesn't support 141 capabilities, assume TDLS is supported internally. When TDLS is 142 explicitly not supported, disable all user facing TDLS operations. 143 - Allow TDLS to be disabled at runtime (mostly for testing). 144 Use set tdls_disabled. 145 - Honor AP TDLS settings that prohibit/allow TDLS. 146 - Add a special testing feature for changing TDLS behavior. Use 147 CONFIG_TDLS_TESTING build param to enable. Configure at runtime 148 with tdls_testing cli command. 149 - Add support for TDLS 802.11z. 150 * wlantest: Add a tool wlantest for IEEE802.11 protocol testing. 151 wlantest can be used to capture frames from a monitor interface 152 for realtime capturing or from pcap files for offline analysis. 153 * Interworking: Support added for 802.11u. Enable in .config with 154 CONFIG_INTERWORKING. See wpa_supplicant.conf for config parameters 155 for interworking. wpa_cli commands added to support this are 156 interworking_select, interworking_connect, anqp_get, fetch_anqp, 157 and stop_fetch_anqp. 158 * Android: Add build and runtime support for Android wpa_supplicant. 159 * bgscan learn: Add new bgscan that learns BSS information based on 160 previous scans, and uses that information to dynamically generate 161 the list of channels for background scans. 162 * Add a new debug message level for excessive information. Use 163 -ddd to enable. 164 * TLS: Add support for tls_disable_time_checks=1 in client mode. 165 * Internal TLS: 166 - Add support for TLS v1.1 (RFC 4346). Enable with build parameter 167 CONFIG_TLSV11. 168 - Add domainComponent parser for X.509 names. 169 * Linux: Add RFKill support by adding an interface state "disabled". 170 * Reorder some IEs to get closer to IEEE 802.11 standard. Move 171 WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames. 172 Move HT IEs to be later in (Re)Assoc Resp. 173 * Solaris: Add support for wired 802.1X client. 174 * Wi-Fi Direct support. See README-P2P for more information. 175 * Many bugfixes. 176 177 2010-04-18 - v0.7.2 178 * nl80211: fixed number of issues with roaming 179 * avoid unnecessary roaming if multiple APs with similar signal 180 strength are present in scan results 181 * add TLS client events and server probing to ease design of 182 automatic detection of EAP parameters 183 * add option for server certificate matching (SHA256 hash of the 184 certificate) instead of trusted CA certificate configuration 185 * bsd: Cleaned up driver wrapper and added various low-level 186 configuration options 187 * wpa_gui-qt4: do not show too frequent WPS AP available events as 188 tray messages 189 * TNC: fixed issues with fragmentation 190 * EAP-TNC: add Flags field into fragment acknowledgement (needed to 191 interoperate with other implementations; may potentially breaks 192 compatibility with older wpa_supplicant/hostapd versions) 193 * wpa_cli: added option for using a separate process to receive event 194 messages to reduce latency in showing these 195 (CFLAGS += -DCONFIG_WPA_CLI_FORK=y in .config to enable this) 196 * maximum BSS table size can now be configured (bss_max_count) 197 * BSSes to be included in the BSS table can be filtered based on 198 configured SSIDs to save memory (filter_ssids) 199 * fix number of issues with IEEE 802.11r/FT; this version is not 200 backwards compatible with old versions 201 * nl80211: add support for IEEE 802.11r/FT protocol (both over-the-air 202 and over-the-DS) 203 * add freq_list network configuration parameter to allow the AP 204 selection to filter out entries based on the operating channel 205 * add signal strength change events for bgscan; this allows more 206 dynamic changes to background scanning interval based on changes in 207 the signal strength with the current AP; this improves roaming within 208 ESS quite a bit, e.g., with bgscan="simple:30:-45:300" in the network 209 configuration block to request background scans less frequently when 210 signal strength remains good and to automatically trigger background 211 scans whenever signal strength drops noticeably 212 (this is currently only available with nl80211) 213 * add BSSID and reason code (if available) to disconnect event messages 214 * wpa_gui-qt4: more complete support for translating the GUI with 215 linguist and add German translation 216 * fix DH padding with internal crypto code (mainly, for WPS) 217 * do not trigger initial scan automatically anymore if there are no 218 enabled networks 219 220 2010-01-16 - v0.7.1 221 * cleaned up driver wrapper API (struct wpa_driver_ops); the new API 222 is not fully backwards compatible, so out-of-tree driver wrappers 223 will need modifications 224 * cleaned up various module interfaces 225 * merge hostapd and wpa_supplicant developers' documentation into a 226 single document 227 * nl80211: use explicit deauthentication to clear cfg80211 state to 228 avoid issues when roaming between APs 229 * dbus: major design changes in the new D-Bus API 230 (fi.w1.wpa_supplicant1) 231 * nl80211: added support for IBSS networks 232 * added internal debugging mechanism with backtrace support and memory 233 allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y) 234 * added WPS ER unsubscription command to more cleanly unregister from 235 receiving UPnP events when ER is terminated 236 * cleaned up AP mode operations to avoid need for virtual driver_ops 237 wrapper 238 * added BSS table to maintain more complete scan result information 239 over multiple scans (that may include only partial results) 240 * wpa_gui-qt4: update Peers dialog information more dynamically while 241 the dialog is kept open 242 * fixed PKCS#12 use with OpenSSL 1.0.0 243 * driver_wext: Added cfg80211-specific optimization to avoid some 244 unnecessary scans and to speed up association 245 246 2009-11-21 - v0.7.0 247 * increased wpa_cli ping interval to 5 seconds and made this 248 configurable with a new command line options (-G<seconds>) 249 * fixed scan buffer processing with WEXT to handle up to 65535 250 byte result buffer (previously, limited to 32768 bytes) 251 * allow multiple driver wrappers to be specified on command line 252 (e.g., -Dnl80211,wext); the first one that is able to initialize the 253 interface will be used 254 * added support for multiple SSIDs per scan request to optimize 255 scan_ssid=1 operations in ap_scan=1 mode (i.e., search for hidden 256 SSIDs); this requires driver support and can currently be used only 257 with nl80211 258 * added support for WPS USBA out-of-band mechanism with USB Flash 259 Drives (UFD) (CONFIG_WPS_UFD=y) 260 * driver_ndis: add PAE group address to the multicast address list to 261 fix wired IEEE 802.1X authentication 262 * fixed IEEE 802.11r key derivation function to match with the standard 263 (note: this breaks interoperability with previous version) [Bug 303] 264 * added better support for drivers that allow separate authentication 265 and association commands (e.g., mac80211-based Linux drivers with 266 nl80211; SME in wpa_supplicant); this allows over-the-air FT protocol 267 to be used (IEEE 802.11r) 268 * fixed SHA-256 based key derivation function to match with the 269 standard when using CCMP (for IEEE 802.11r and IEEE 802.11w) 270 (note: this breaks interoperability with previous version) [Bug 307] 271 * use shared driver wrapper files with hostapd 272 * added AP mode functionality (CONFIG_AP=y) with mode=2 in the network 273 block; this can be used for open and WPA2-Personal networks 274 (optionally, with WPS); this links in parts of hostapd functionality 275 into wpa_supplicant 276 * wpa_gui-qt4: added new Peers dialog to show information about peers 277 (other devices, including APs and stations, etc. in the neighborhood) 278 * added support for WPS External Registrar functionality (configure APs 279 and enroll new devices); can be used with wpa_gui-qt4 Peers dialog 280 and wpa_cli commands wps_er_start, wps_er_stop, wps_er_pin, 281 wps_er_pbc, wps_er_learn 282 (this can also be used with a new 'none' driver wrapper if no 283 wireless device or IEEE 802.1X on wired is needed) 284 * driver_nl80211: multiple updates to provide support for new Linux 285 nl80211/mac80211 functionality 286 * updated management frame protection to use IEEE Std 802.11w-2009 287 * fixed number of small WPS issues and added workarounds to 288 interoperate with common deployed broken implementations 289 * added support for NFC out-of-band mechanism with WPS 290 * driver_ndis: fixed wired IEEE 802.1X authentication with PAE group 291 address frames 292 * added preliminary support for IEEE 802.11r RIC processing 293 * added support for specifying subset of enabled frequencies to scan 294 (scan_freq option in the network configuration block); this can speed 295 up scanning process considerably if it is known that only a small 296 subset of channels is actually used in the network (this is currently 297 supported only with -Dnl80211) 298 * added a workaround for race condition between receiving the 299 association event and the following EAPOL-Key 300 * added background scan and roaming infrastructure to allow 301 network-specific optimizations to be used to improve roaming within 302 an ESS (same SSID) 303 * added new DBus interface (fi.w1.wpa_supplicant1) 304 305 2009-01-06 - v0.6.7 306 * added support for Wi-Fi Protected Setup (WPS) 307 (wpa_supplicant can now be configured to act as a WPS Enrollee to 308 enroll credentials for a network using PIN and PBC methods; in 309 addition, wpa_supplicant can act as a wireless WPS Registrar to 310 configure an AP); WPS support can be enabled by adding CONFIG_WPS=y 311 into .config and setting the runtime configuration variables in 312 wpa_supplicant.conf (see WPS section in the example configuration 313 file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to 314 manage WPS negotiation; see README-WPS for more details 315 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf) 316 * added support for using driver_test over UDP socket 317 * fixed PEAPv0 Cryptobinding interoperability issue with Windows Server 318 2008 NPS; optional cryptobinding is now enabled (again) by default 319 * fixed PSK editing in wpa_gui 320 * changed EAP-GPSK to use the IANA assigned EAP method type 51 321 * added a Windows installer that includes WinPcap and all the needed 322 DLLs; in addition, it set up the registry automatically so that user 323 will only need start wpa_gui to get prompted to start the wpasvc 324 servide and add a new interface if needed through wpa_gui dialog 325 * updated management frame protection to use IEEE 802.11w/D7.0 326 327 2008-11-23 - v0.6.6 328 * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA 329 (can be used to simulate test SIM/USIM card with a known private key; 330 enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config 331 and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration) 332 * added a new network configuration option, wpa_ptk_rekey, that can be 333 used to enforce frequent PTK rekeying, e.g., to mitigate some attacks 334 against TKIP deficiencies 335 * added an optional mitigation mechanism for certain attacks against 336 TKIP by delaying Michael MIC error reports by a random amount of time 337 between 0 and 60 seconds; this can be enabled with a build option 338 CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config 339 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits, 340 not bytes 341 * updated OpenSSL code for EAP-FAST to use an updated version of the 342 session ticket overriding API that was included into the upstream 343 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is 344 needed with that version anymore) 345 * updated userspace MLME instructions to match with the current Linux 346 mac80211 implementation; please also note that this can only be used 347 with driver_nl80211.c (the old code from driver_wext.c was removed) 348 * added support (Linux only) for RoboSwitch chipsets (often found in 349 consumer grade routers); driver interface 'roboswitch' 350 * fixed canceling of PMKSA caching when using drivers that generate 351 RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know 352 about 353 354 2008-11-01 - v0.6.5 355 * added support for SHA-256 as X.509 certificate digest when using the 356 internal X.509/TLSv1 implementation 357 * updated management frame protection to use IEEE 802.11w/D6.0 358 * added support for using SHA256-based stronger key derivation for WPA2 359 (IEEE 802.11w) 360 * fixed FT (IEEE 802.11r) authentication after a failed association to 361 use correct FTIE 362 * added support for configuring Phase 2 (inner/tunneled) authentication 363 method with wpa_gui-qt4 364 365 2008-08-10 - v0.6.4 366 * added support for EAP Sequences in EAP-FAST Phase 2 367 * added support for using TNC with EAP-FAST 368 * added driver_ps3 for the PS3 Linux wireless driver 369 * added support for optional cryptobinding with PEAPv0 370 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to 371 allow fallback to full handshake if server rejects PAC-Opaque 372 * added fragmentation support for EAP-TNC 373 * added support for parsing PKCS #8 formatted private keys into the 374 internal TLS implementation (both PKCS #1 RSA key and PKCS #8 375 encapsulated RSA key can now be used) 376 * added option of using faster, but larger, routines in the internal 377 LibTomMath (for internal TLS implementation) to speed up DH and RSA 378 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y) 379 * fixed race condition between disassociation event and group key 380 handshake to avoid getting stuck in incorrect state [Bug 261] 381 * fixed opportunistic key caching (proactive_key_caching) 382 383 2008-02-22 - v0.6.3 384 * removed 'nai' and 'eappsk' network configuration variables that were 385 previously used for configuring user identity and key for EAP-PSK, 386 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the 387 replacement for 'nai' (if old configuration used a separate 388 'identity' value, that would now be configured as 389 'anonymous_identity'). 'password' field is now used as the 390 replacement for 'eappsk' (it can also be set using hexstring to 391 present random binary data) 392 * removed '-w' command line parameter (wait for interface to be added, 393 if needed); cleaner way of handling this functionality is to use an 394 external mechanism (e.g., hotplug scripts) that start wpa_supplicant 395 when an interface is added 396 * updated FT support to use the latest draft, IEEE 802.11r/D9.0 397 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for 398 indicating when new scan results become available 399 * added new ctrl_iface command, BSS, to allow scan results to be 400 fetched without hitting the message size limits (this command 401 can be used to iterate through the scan results one BSS at the time) 402 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION 403 attributes in EAP-SIM Start/Response when using fast reauthentication 404 * fixed EAPOL not to end up in infinite loop when processing dynamic 405 WEP keys with IEEE 802.1X 406 * fixed problems in getting NDIS events from WMI on Windows 2000 407 408 2008-01-01 - v0.6.2 409 * added support for Makefile builds to include debug-log-to-a-file 410 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line) 411 * fixed EAP-SIM and EAP-AKA message parser to validate attribute 412 lengths properly to avoid potential crash caused by invalid messages 413 * added data structure for storing allocated buffers (struct wpabuf); 414 this does not affect wpa_supplicant usage, but many of the APIs 415 changed and various interfaces (e.g., EAP) is not compatible with old 416 versions 417 * added support for protecting EAP-AKA/Identity messages with 418 AT_CHECKCODE (optional feature in RFC 4187) 419 * added support for protected result indication with AT_RESULT_IND for 420 EAP-SIM and EAP-AKA (phase1="result_ind=1") 421 * added driver_wext workaround for race condition between scanning and 422 association with drivers that take very long time to scan all 423 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now 424 using a longer hardcoded timeout for the scan if the driver supports 425 notifications for scan completion (SIOCGIWSCAN event); this helps, 426 e.g., in cases where wpa_supplicant and madwifi driver ended up in 427 loop where the driver did not even try to associate 428 * stop EAPOL timer tick when no timers are in use in order to reduce 429 power consumption (no need to wake up the process once per second) 430 [Bug 237] 431 * added support for privilege separation (run only minimal part of 432 wpa_supplicant functionality as root and rest as unprivileged, 433 non-root process); see 'Privilege separation' in README for details; 434 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y 435 in .config 436 * changed scan results data structure to include all information 437 elements to make it easier to support new IEs; old get_scan_result() 438 driver_ops is still supported for backwards compatibility (results 439 are converted internally to the new format), but all drivers should 440 start using the new get_scan_results2() to make them more likely to 441 work with new features 442 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4 443 application, i.e., it does not require Qt3Support anymore; Windows 444 binary of wpa_gui.exe is now from this directory and only requires 445 QtCore4.dll and QtGui4.dll libraries 446 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs 447 available as a separate package to make wpa_gui installation easier: 448 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip 449 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt); 450 only shared key/password authentication is supported in this version 451 452 2007-11-24 - v0.6.1 453 * added support for configuring password as NtPasswordHash 454 (16-byte MD4 hash of password) in hash:<32 hex digits> format 455 * added support for fallback from abbreviated TLS handshake to 456 full handshake when using EAP-FAST (e.g., due to an expired 457 PAC-Opaque) 458 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 459 draft (draft-ietf-emu-eap-gpsk-07.txt) 460 * added support for drivers that take care of RSN 4-way handshake 461 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and 462 WPA_ALG_PMK in set_key) 463 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in 464 .config); this version supports only ap_scan=2 mode and allow the 465 driver to take care of the 4-way handshake 466 * fixed a buffer overflow in parsing TSF from scan results when using 467 driver_wext.c with a driver that includes the TSF (e.g., iwl4965) 468 [Bug 232] 469 * updated FT support to use the latest draft, IEEE 802.11r/D8.0 470 * fixed an integer overflow issue in the ASN.1 parser used by the 471 (experimental) internal TLS implementation to avoid a potential 472 buffer read overflow 473 * fixed a race condition with -W option (wait for a control interface 474 monitor before starting) that could have caused the first messages to 475 be lost 476 * added support for processing TNCC-TNCS-Messages to report 477 recommendation (allow/none/isolate) when using TNC [Bug 243] 478 479 2007-05-28 - v0.6.0 480 * added network configuration parameter 'frequency' for setting 481 initial channel for IBSS (adhoc) networks 482 * added experimental IEEE 802.11r/D6.0 support 483 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48 484 * updated EAP-PSK to use the IANA-allocated EAP type 47 485 * fixed EAP-PAX key derivation 486 * fixed EAP-PSK bit ordering of the Flags field 487 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in 488 tunnelled identity request (previously, the identifier from the outer 489 method was used, not the tunnelled identifier which could be 490 different) 491 * added support for fragmentation of outer TLS packets during Phase 2 492 of EAP-PEAP/TTLS/FAST 493 * fixed EAP-TTLS AVP parser processing for too short AVP lengths 494 * added support for EAP-FAST authentication with inner methods that 495 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported 496 for PAC provisioning) 497 * added support for authenticated EAP-FAST provisioning 498 * added support for configuring maximum number of EAP-FAST PACs to 499 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string) 500 * added support for storing EAP-FAST PACs in binary format 501 (fast_pac_format=binary in phase1 string) 502 * fixed dbus ctrl_iface to validate message interface before 503 dispatching to avoid a possible segfault [Bug 190] 504 * fixed PeerKey key derivation to use the correct PRF label 505 * updated Windows binary build to link against OpenSSL 0.9.8d and 506 added support for EAP-FAST 507 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 508 draft (draft-ietf-emu-eap-gpsk-04.txt) 509 * fixed EAP-AKA Notification processing to allow Notification to be 510 processed after AKA Challenge response has been sent 511 * updated to use IEEE 802.11w/D2.0 for management frame protection 512 (still experimental) 513 * fixed EAP-TTLS implementation not to crash on use of freed memory 514 if TLS library initialization fails 515 * added support for EAP-TNC (Trusted Network Connect) 516 (this version implements the EAP-TNC method and EAP-TTLS changes 517 needed to run two methods in sequence (IF-T) and the IF-IMC and 518 IF-TNCCS interfaces from TNCC) 519 520 2006-11-24 - v0.5.6 521 * added experimental, integrated TLSv1 client implementation with the 522 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by 523 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in 524 .config); this can be useful, e.g., if the target system does not 525 have a suitable TLS library and a minimal code size is required 526 (total size of this internal TLS/crypto code is bit under 50 kB on 527 x86 and the crypto code is shared by rest of the supplicant so some 528 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB) 529 * removed STAKey handshake since PeerKey handshake has replaced it in 530 IEEE 802.11ma and there are no known deployments of STAKey 531 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 532 draft (draft-ietf-emu-eap-gpsk-01.txt) 533 * added preliminary implementation of IEEE 802.11w/D1.0 (management 534 frame protection) 535 (Note: this requires driver support to work properly.) 536 (Note2: IEEE 802.11w is an unapproved draft and subject to change.) 537 * fixed Windows named pipes ctrl_iface to not stop listening for 538 commands if client program opens a named pipe and closes it 539 immediately without sending a command 540 * fixed USIM PIN status determination for the case that PIN is not 541 needed (this allows EAP-AKA to be used with USIM cards that do not 542 use PIN) 543 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to 544 be used with cards that do not support file selection based on 545 partial AID 546 * added support for matching the subjectAltName of the authentication 547 server certificate against multiple name components (e.g., 548 altsubject_match="DNS:server.example.com;DNS:server2.example.com") 549 * fixed EAP-SIM/AKA key derivation for re-authentication case (only 550 affects IEEE 802.1X with dynamic WEP keys) 551 * changed ctrl_iface network configuration 'get' operations to not 552 return password/key material; if these fields are requested, "*" 553 will be returned if the password/key is set, but the value of the 554 parameter is not exposed 555 556 2006-08-27 - v0.5.5 557 * added support for building Windows version with UNICODE defined 558 (wide-char functions) 559 * driver_ndis: fixed static WEP configuration to avoid race condition 560 issues with some NDIS drivers between association and setting WEP 561 keys 562 * driver_ndis: added validation for IELength value in scan results to 563 avoid crashes when using buggy NDIS drivers [Bug 165] 564 * fixed Release|Win32 target in the Visual Studio project files 565 (previously, only Debug|Win32 target was set properly) 566 * changed control interface API call wpa_ctrl_pending() to allow it to 567 return -1 on error (e.g., connection lost); control interface clients 568 will need to make sure that they verify that the value is indeed >0 569 when determining whether there are pending messages 570 * added an alternative control interface backend for Windows targets: 571 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default 572 control interface mechanism for Windows builds (previously, UDP to 573 localhost was used) 574 * changed ctrl_interface configuration for UNIX domain sockets: 575 - deprecated ctrl_interface_group variable (it may be removed in 576 future versions) 577 - allow both directory and group be configured with ctrl_interface 578 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel 579 - ctrl_interface=/var/run/wpa_supplicant is still supported for the 580 case when group is not changed 581 * added support for controlling more than one interface per process in 582 Windows version 583 * added a workaround for a case where the AP is using unknown address 584 (e.g., MAC address of the wired interface) as the source address for 585 EAPOL-Key frames; previously, that source address was used as the 586 destination for EAPOL-Key frames and in key derivation; now, BSSID is 587 used even if the source address does not match with it 588 (this resolves an interoperability issue with Thomson SpeedTouch 580) 589 * added a workaround for UDP-based control interface (which was used in 590 Windows builds before this release) to prevent packets with forged 591 addresses from being accepted as local control requests 592 * removed ndis_events.cpp and possibility of using external 593 ndis_events.exe; C version (ndis_events.c) is fully functional and 594 there is no desire to maintain two separate versions of this 595 implementation 596 * ndis_events: Changed NDIS event notification design to use WMI to 597 learn the adapter description through Win32_PnPEntity class; this 598 should fix some cases where the adapter name was not recognized 599 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500 600 USB) [Bug 113] 601 * fixed selection of the first network in ap_scan=2 mode; previously, 602 wpa_supplicant could get stuck in SCANNING state when only the first 603 network for enabled (e.g., after 'wpa_cli select_network 0') 604 * winsvc: added support for configuring ctrl_interface parameters in 605 registry (ctrl_interface string value in 606 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is 607 required to enable control interface (previously, this was hardcoded 608 to be enabled) 609 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4 610 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format 611 612 2006-06-20 - v0.5.4 613 * fixed build with CONFIG_STAKEY=y [Bug 143] 614 * added support for doing MLME (IEEE 802.11 management frame 615 processing) in wpa_supplicant when using Devicescape IEEE 802.11 616 stack (wireless-dev.git tree) 617 * added a new network block configuration option, fragment_size, to 618 configure the maximum EAP fragment size 619 * driver_ndis: Disable WZC automatically for the selected interface to 620 avoid conflicts with two programs trying to control the radio; WZC 621 will be re-enabled (if it was enabled originally) when wpa_supplicant 622 is terminated 623 * added an experimental TLSv1 client implementation 624 (CONFIG_TLS=internal) that can be used instead of an external TLS 625 library, e.g., to reduce total size requirement on systems that do 626 not include any TLS library by default (this is not yet complete; 627 basic functionality is there, but certificate validation is not yet 628 included) 629 * added PeerKey handshake implementation for IEEE 802.11e 630 direct link setup (DLS) to replace STAKey handshake 631 * fixed WPA PSK update through ctrl_iface for the case where the old 632 PSK was derived from an ASCII passphrase and the new PSK is set as 633 a raw PSK (hex string) 634 * added new configuration option for identifying which network block 635 was used (id_str in wpa_supplicant.conf; included on 636 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental 637 variable in wpa_cli action scripts; in addition WPA_ID variable is 638 set to the current unique identifier that wpa_supplicant assigned 639 automatically for the network and that can be used with 640 GET_NETWORK/SET_NETWORK ctrl_iface commands) 641 * wpa_cli action script is now called only when the connect/disconnect 642 status changes or when associating with a different network 643 * fixed configuration parser not to remove CCMP from group cipher list 644 if WPA-None (adhoc) is used (pairwise=NONE in that case) 645 * fixed integrated NDIS events processing not to hang the process due 646 to a missed change in eloop_win.c API in v0.5.3 [Bug 155] 647 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK, 648 draft-clancy-emu-eap-shared-secret-00.txt) 649 * added Microsoft Visual Studio 2005 solution and project files for 650 build wpa_supplicant for Windows (see vs2005 subdirectory) 651 * eloop_win: fixed unregistration of Windows events 652 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet 653 at the end of RSN pre-authentication and added unregistration of 654 a Windows event to avoid getting eloop_win stuck with an invalid 655 handle 656 * driver_ndis: added support for selecting AP based on BSSID 657 * added new environmental variable for wpa_cli action scripts: 658 WPA_CTRL_DIR is the current control interface directory 659 * driver_ndis: added support for using NDISUIO instead of WinPcap for 660 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new 661 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build 662 wpa_supplicant without requiring WinPcap; note that using NDISUIO 663 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows 664 only one application to open the device 665 * changed NDIS driver naming to only include device GUID, e.g., 666 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap 667 specific \Device\NPF_ prefix before the GUID; the prefix is still 668 allowed for backwards compatibility, but it is not required anymore 669 when specifying the interface 670 * driver_ndis: re-initialize driver interface is the adapter is removed 671 and re-inserted [Bug 159] 672 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on 673 big endian hosts [Bug 146] 674 675 2006-04-27 - v0.5.3 676 * fixed EAP-GTC response to include correct user identity when run as 677 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2) 678 * driver_ndis: Fixed encryption mode configuration for unencrypted 679 networks (some NDIS drivers ignored this, but others, e.g., Broadcom, 680 refused to associate with open networks) [Bug 106] 681 * driver_ndis: use BSSID OID polling to detect when IBSS network is 682 formed even when ndis_events code is included since some NDIS drivers 683 do not generate media connect events in IBSS mode 684 * config_winreg: allow global ctrl_interface parameter to be configured 685 in Windows registry 686 * config_winreg: added support for saving configuration data into 687 Windows registry 688 * added support for controlling network device operational state 689 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see 690 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client 691 that can use this information) 692 * driver_wext: added support for WE-21 change to SSID configuration 693 * driver_wext: fixed privacy configuration for static WEP keys mode 694 [Bug 140] 695 * added an optional driver_ops callback for MLME-SETPROTECTION.request 696 primitive 697 * added support for EAP-SAKE (no EAP method number allocated yet, so 698 this is using the same experimental type 255 as EAP-PSK) 699 * added support for dynamically loading EAP methods (.so files) instead 700 of requiring them to be statically linked in; this is disabled by 701 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information 702 on how to use this) 703 704 2006-03-19 - v0.5.2 705 * do not try to use USIM APDUs when initializing PC/SC for SIM card 706 access for a network that has not enabled EAP-AKA 707 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in 708 v0.5.1 due to the new support for expanded EAP types) 709 * added support for generating EAP Expanded Nak 710 * try to fetch scan results once before requesting new scan when 711 starting up in ap_scan=1 mode (this can speed up initial association 712 a lot with, e.g., madwifi-ng driver) 713 * added support for receiving EAPOL frames from a Linux bridge 714 interface (-bbr0 on command line) 715 * fixed EAPOL re-authentication for sessions that used PMKSA caching 716 * changed EAP method registration to use a dynamic list of methods 717 instead of a static list generated at build time 718 * fixed PMKSA cache deinitialization not to use freed memory when 719 removing PMKSA entries 720 * fixed a memory leak in EAP-TTLS re-authentication 721 * reject WPA/WPA2 message 3/4 if it does not include any valid 722 WPA/RSN IE 723 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg 724 if the driver does not support SIOCSIWAUTH 725 726 2006-01-29 - v0.5.1 727 * driver_test: added better support for multiple APs and STAs by using 728 a directory with sockets that include MAC address for each device in 729 the name (driver_param=test_dir=/tmp/test) 730 * added support for EAP expanded type (vendor specific EAP methods) 731 * added AP_SCAN command into ctrl_iface so that ap_scan configuration 732 option can be changed if needed 733 * wpa_cli/wpa_gui: skip non-socket files in control directory when 734 using UNIX domain sockets; this avoids selecting an incorrect 735 interface (e.g., a PID file could be in this directory, even though 736 use of this directory for something else than socket files is not 737 recommended) 738 * fixed TLS library deinitialization after RSN pre-authentication not 739 to disable TLS library for normal authentication 740 * driver_wext: Remove null-termination from SSID length if the driver 741 used it; some Linux drivers do this and they were causing problems in 742 wpa_supplicant not finding matching configuration block. This change 743 would break a case where the SSID actually ends in '\0', but that is 744 not likely to happen in real use. 745 * fixed PMKSA cache processing not to trigger deauthentication if the 746 current PMKSA cache entry is replaced with a valid new entry 747 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes 748 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or 749 ap_scan=2) 750 751 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases) 752 * added experimental STAKey handshake implementation for IEEE 802.11e 753 direct link setup (DLS); note: this is disabled by default in both 754 build and runtime configuration (can be enabled with CONFIG_STAKEY=y 755 and stakey=1) 756 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to 757 decrypt AT_ENCR_DATA attributes correctly 758 * fixed EAP-AKA to allow resynchronization within the same session 759 * made code closer to ANSI C89 standard to make it easier to port to 760 other C libraries and compilers 761 * started moving operating system or C library specific functions into 762 wrapper functions defined in os.h and implemented in os_*.c to make 763 code more portable 764 * wpa_supplicant can now be built with Microsoft Visual C++ 765 (e.g., with the freely available Toolkit 2003 version or Visual 766 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an 767 example makefile for nmake 768 * added support for using Windows registry for command line parameters 769 (CONFIG_MAIN=main_winsvc) and configuration data 770 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry 771 contents; this version can be run both as a Windows service and as a 772 normal application; 'wpasvc.exe app' to start as applicant, 773 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service, 774 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to 775 unregister a service 776 * made it possible to link ndis_events.exe functionality into 777 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED 778 * added better support for multiple control interface backends 779 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported 780 * fixed PC/SC code to use correct length for GSM AUTH command buffer 781 and to not use pioRecvPci with SCardTransmit() calls; these were not 782 causing visible problems with pcsc-lite, but Windows Winscard.dll 783 refused the previously used parameters; this fixes EAP-SIM and 784 EAP-AKA authentication using SIM/USIM card under Windows 785 * added new event loop implementation for Windows using 786 WaitForMultipleObject() instead of select() in order to allow waiting 787 for non-socket objects; this can be selected with 788 CONFIG_ELOOP=eloop_win in .config 789 * added support for selecting l2_packet implementation in .config 790 (CONFIG_L2_PACKET; following options are available now: linux, pcap, 791 winpcap, freebsd, none) 792 * added new l2_packet implementation for WinPcap 793 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to 794 reduce latency in EAPOL receive processing from about 100 ms to about 795 3 ms 796 * added support for EAP-FAST key derivation using other ciphers than 797 RC4-128-SHA for authentication and AES128-SHA for provisioning 798 * added support for configuring CA certificate as DER file and as a 799 configuration blob 800 * fixed private key configuration as configuration blob and added 801 support for using PKCS#12 as a blob 802 * tls_gnutls: added support for using PKCS#12 files; added support for 803 session resumption 804 * added support for loading trusted CA certificates from Windows 805 certificate store: ca_cert="cert_store://<name>", where <name> is 806 likely CA (Intermediate CA certificates) or ROOT (root certificates) 807 * added C version of ndis_events.cpp and made it possible to build this 808 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more 809 easily on cross-compilation builds 810 * added wpasvc.exe into Windows binary release; this is an alternative 811 version of wpa_supplicant.exe with configuration backend using 812 Windows registry and with the entry point designed to run as a 813 Windows service 814 * integrated ndis_events.exe functionality into wpa_supplicant.exe and 815 wpasvc.exe and removed this additional tool from the Windows binary 816 release since it is not needed anymore 817 * load winscard.dll functions dynamically when building with MinGW 818 since MinGW does not yet include winscard library 819 820 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases) 821 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap 822 and WinPcap to receive frames sent to PAE group address 823 * disable EAP state machine when IEEE 802.1X authentication is not used 824 in order to get rid of bogus "EAP failed" messages 825 * fixed OpenSSL error reporting to go through all pending errors to 826 avoid confusing reports of old errors being reported at later point 827 during handshake 828 * fixed configuration file updating to not write empty variables 829 (e.g., proto or key_mgmt) that the file parser would not accept 830 * fixed ADD_NETWORK ctrl_iface command to use the same default values 831 for variables as empty network definitions read from config file 832 would get 833 * fixed EAP state machine to not discard EAP-Failure messages in many 834 cases (e.g., during TLS handshake) 835 * fixed a infinite loop in private key reading if the configured file 836 cannot be parsed successfully 837 * driver_madwifi: added support for madwifi-ng 838 * wpa_gui: do not display password/PSK field contents 839 * wpa_gui: added CA certificate configuration 840 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID 841 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if 842 the new AP is using different WPA/RSN IE 843 * use longer timeout for IEEE 802.11 association to avoid problems with 844 drivers that may take more than five second to associate 845 846 2005-10-27 - v0.4.6 847 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in 848 RSN IE, but WPA IE would match with wpa_supplicant configuration 849 * added support for named configuration blobs in order to avoid having 850 to use file system for external files (e.g., certificates); 851 variables can be set to "blob://<blob name>" instead of file path to 852 use a named blob; supported fields: pac_file, client_cert, 853 private_key 854 * fixed RSN pre-authentication (it was broken in the clean up of WPA 855 state machine interface in v0.4.5) 856 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make 857 sure the driver configures broadcast decryption correctly 858 * added ca_path (and ca_path2) configuration variables that can be used 859 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the 860 system-wide trusted CA list 861 * added support for starting wpa_supplicant without a configuration 862 file (-C argument must be used to set ctrl_interface parameter for 863 this case; in addition, -p argument can be used to provide 864 driver_param; these new arguments can also be used with a 865 configuration to override the values from the configuration) 866 * added global control interface that can be optionally used for adding 867 and removing network interfaces dynamically (-g command line argument 868 for both wpa_supplicant and wpa_cli) without having to restart 869 wpa_supplicant process 870 * wpa_gui: 871 - try to save configuration whenever something is modified 872 - added WEP key configuration 873 - added possibility to edit the current network configuration 874 * driver_ndis: fixed driver polling not to increase frequency on each 875 received EAPOL frame due to incorrectly cancelled timeout 876 * added simple configuration file examples (in examples subdirectory) 877 * fixed driver_wext.c to filter wireless events based on ifindex to 878 avoid interfaces receiving events from other interfaces 879 * delay sending initial EAPOL-Start couple of seconds to speed up 880 authentication for the most common case of Authenticator starting 881 EAP authentication immediately after association 882 883 2005-09-25 - v0.4.5 884 * added a workaround for clearing keys with ndiswrapper to allow 885 roaming from WPA enabled AP to plaintext one 886 * added docbook documentation (doc/docbook) that can be used to 887 generate, e.g., man pages 888 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for 889 PF_PACKET in order to prepare for network devices that do not use 890 Ethernet headers (e.g., network stack with native IEEE 802.11 frames) 891 * use receipt of EAPOL-Key frame as a lower layer success indication 892 for EAP state machine to allow recovery from dropped EAP-Success 893 frame 894 * cleaned up internal EAPOL frame processing by not including link 895 layer (Ethernet) header during WPA and EAPOL/EAP processing; this 896 header is added only when transmitted the frame; this makes it easier 897 to use wpa_supplicant on link layers that use different header than 898 Ethernet 899 * updated EAP-PSK to use draft 9 by default since this can now be 900 tested with hostapd; removed support for draft 3, including 901 server_nai configuration option from network blocks 902 * driver_wired: add PAE address to the multicast address list in order 903 to be able to receive EAPOL frames with drivers that do not include 904 these multicast addresses by default 905 * driver_wext: add support for WE-19 906 * added support for multiple configuration backends (CONFIG_BACKEND 907 option); currently, only 'file' is supported (i.e., the format used 908 in wpa_supplicant.conf) 909 * added support for updating configuration ('wpa_cli save_config'); 910 this is disabled by default and can be enabled with global 911 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli 912 and wpa_gui to store the configuration changes in a permanent store 913 * added GET_NETWORK ctrl_iface command 914 (e.g., 'wpa_cli get_network 0 ssid') 915 916 2005-08-21 - v0.4.4 917 * replaced OpenSSL patch for EAP-FAST support 918 (openssl-tls-extensions.patch) with a more generic and correct 919 patch (the new patch is not compatible with the previous one, so the 920 OpenSSL library will need to be patched with the new patch in order 921 to be able to build wpa_supplicant with EAP-FAST support) 922 * added support for using Windows certificate store (through CryptoAPI) 923 for client certificate and private key operations (EAP-TLS) 924 (see wpa_supplicant.conf for more information on how to configure 925 this with private_key) 926 * ported wpa_gui to Windows 927 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be 928 built with the open source version of the Qt4 for Windows 929 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used 930 with drivers that do not support WPA 931 * ndis_events: fixed Windows 2000 support 932 * added support for enabling/disabling networks from the list of all 933 configured networks ('wpa_cli enable_network <network id>' and 934 'wpa_cli disable_network <network id>') 935 * added support for adding and removing network from the current 936 configuration ('wpa_cli add_network' and 'wpa_cli remove_network 937 <network id>'); added networks are disabled by default and they can 938 be enabled with enable_network command once the configuration is done 939 for the new network; note: configuration file is not yet updated, so 940 these new networks are lost when wpa_supplicant is restarted 941 * added support for setting network configuration parameters through 942 the control interface, for example: 943 wpa_cli set_network 0 ssid "\"my network\"" 944 * fixed parsing of strings that include both " and # within double 945 quoted area (e.g., "start"#end") 946 * added EAP workaround for PEAP session resumption: allow outer, 947 i.e., not tunneled, EAP-Success to terminate session since; this can 948 be disabled with eap_workaround=0 949 (this was allowed for PEAPv1 before, but now it is also allowed for 950 PEAPv0 since at least one RADIUS authentication server seems to be 951 doing this for PEAPv0, too) 952 * wpa_gui: added preliminary support for adding new networks to the 953 wpa_supplicant configuration (double click on the scan results to 954 open network configuration) 955 956 2005-06-26 - v0.4.3 957 * removed interface for external EAPOL/EAP supplicant (e.g., 958 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required 959 anymore and is unlikely to be used by anyone 960 * driver_ndis: fixed WinPcap 3.0 support 961 * fixed build with CONFIG_DNET_PCAP=y on Linux 962 * l2_packet: moved different implementations into separate files 963 (l2_packet_*.c) 964 965 2005-06-12 - v0.4.2 966 * driver_ipw: updated driver structures to match with ipw2200-1.0.4 967 (note: ipw2100-1.1.0 is likely to require an update to work with 968 this) 969 * added support for using ap_scan=2 mode with multiple network blocks; 970 wpa_supplicant will go through the networks one by one until the 971 driver reports a successful association; this uses the same order for 972 networks as scan_ssid=1 scans, i.e., the priority field is ignored 973 and the network block order in the file is used instead 974 * fixed a potential issue in RSN pre-authentication ending up using 975 freed memory if pre-authentication times out 976 * added support for matching alternative subject name extensions of the 977 authentication server certificate; new configuration variables 978 altsubject_match and altsubject_match2 979 * driver_ndis: added support for IEEE 802.1X authentication with wired 980 NDIS drivers 981 * added support for querying private key password (EAP-TLS) through the 982 control interface (wpa_cli/wpa_gui) if one is not included in the 983 configuration file 984 * driver_broadcom: fixed couple of memory leaks in scan result 985 processing 986 * EAP-PAX is now registered as EAP type 46 987 * fixed EAP-PAX MAC calculation 988 * fixed EAP-PAX CK and ICK key derivation 989 * added support for using password with EAP-PAX (as an alternative to 990 entering key with eappsk); SHA-1 hash of the password will be used as 991 the key in this case 992 * added support for arbitrary driver interface parameters through the 993 configuration file with a new driver_param field; this adds a new 994 driver_ops function set_param() 995 * added possibility to override l2_packet module with driver interface 996 API (new send_eapol handler); this can be used to implement driver 997 specific TX/RX functions for EAPOL frames 998 * fixed ctrl_interface_group processing for the case where gid is 999 entered as a number, not group name 1000 * driver_test: added support for testing hostapd with wpa_supplicant 1001 by using test driver interface without any kernel drivers or network 1002 cards 1003 1004 2005-05-22 - v0.4.1 1005 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL 1006 packets to be encrypted; this was apparently broken by the changed 1007 ioctl order in v0.4.0 1008 * driver_madwifi: added preliminary support for compiling against 'BSD' 1009 branch of madwifi CVS tree 1010 * added support for EAP-MSCHAPv2 password retries within the same EAP 1011 authentication session 1012 * added support for password changes with EAP-MSCHAPv2 (used when the 1013 password has expired) 1014 * added support for reading additional certificates from PKCS#12 files 1015 and adding them to the certificate chain 1016 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys 1017 were used 1018 * fixed a possible double free in EAP-TTLS fast-reauthentication when 1019 identity or password is entered through control interface 1020 * display EAP Notification messages to user through control interface 1021 with "CTRL-EVENT-EAP-NOTIFICATION" prefix 1022 * added GUI version of wpa_cli, wpa_gui; this is not build 1023 automatically with 'make'; use 'make wpa_gui' to build (this requires 1024 Qt development tools) 1025 * added 'disconnect' command to control interface for setting 1026 wpa_supplicant in state where it will not associate before 1027 'reassociate' command has been used 1028 * added support for selecting a network from the list of all configured 1029 networks ('wpa_cli select_network <network id>'; this disabled all 1030 other networks; to re-enable, 'wpa_cli select_network any') 1031 * added support for getting scan results through control interface 1032 * added EAP workaround for PEAPv1 session resumption: allow outer, 1033 i.e., not tunneled, EAP-Success to terminate session since; this can 1034 be disabled with eap_workaround=0 1035 1036 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases) 1037 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be 1038 used to reduce the size of the wpa_supplicant considerably if 1039 debugging code is not needed 1040 * fixed EAPOL-Key validation to drop packets with invalid Key Data 1041 Length; such frames could have crashed wpa_supplicant due to buffer 1042 overflow 1043 * added support for wired authentication (IEEE 802.1X on wired 1044 Ethernet); driver interface 'wired' 1045 * obsoleted set_wpa() handler in the driver interface API (it can be 1046 replaced by moving enable/disable functionality into init()/deinit()) 1047 (calls to set_wpa() are still present for backwards compatibility, 1048 but they may be removed in the future) 1049 * driver_madwifi: fixed association in plaintext mode 1050 * modified the EAP workaround that accepts EAP-Success with incorrect 1051 Identifier to be even less strict about verification in order to 1052 interoperate with some authentication servers 1053 * added support for sending TLS alerts 1054 * added support for 'any' SSID wildcard; if ssid is not configured or 1055 is set to an empty string, any SSID will be accepted for non-WPA AP 1056 * added support for asking PIN (for SIM) from frontends (e.g., 1057 wpa_cli); if a PIN is needed, but not included in the configuration 1058 file, a control interface request is sent and EAP processing is 1059 delayed until the PIN is available 1060 * added support for using external devices (e.g., a smartcard) for 1061 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config); 1062 new wpa_supplicant.conf variables: 1063 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path 1064 - network: engine, engine_id, key_id 1065 * added experimental support for EAP-PAX 1066 * added monitor mode for wpa_cli (-a<path to a program to run>) that 1067 allows external commands (e.g., shell scripts) to be run based on 1068 wpa_supplicant events, e.g., when authentication has been completed 1069 and data connection is ready; other related wpa_cli arguments: 1070 -B (run in background), -P (write PID file); wpa_supplicant has a new 1071 command line argument (-W) that can be used to make it wait until a 1072 control interface command is received in order to avoid missing 1073 events 1074 * added support for opportunistic WPA2 PMKSA key caching (disabled by 1075 default, can be enabled with proactive_key_caching=1) 1076 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where 1077 Authenticator rejects PMKSA caching attempt and the driver is not 1078 using assoc_info events 1079 * added -P<pid file> argument for wpa_supplicant to write the current 1080 process id into a file 1081 1082 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases) 1083 * added new phase1 option parameter, include_tls_length=1, to force 1084 wpa_supplicant to add TLS Message Length field to all TLS messages 1085 even if the packet is not fragmented; this may be needed with some 1086 authentication servers 1087 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when 1088 using drivers that take care of AP selection (e.g., when using 1089 ap_scan=2) 1090 * fixed reprocessing of pending request after ctrl_iface requests for 1091 identity/password/otp 1092 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of 1093 EAP-PEAP and EAP-TTLS 1094 * all drivers using driver_wext: set interface up and select Managed 1095 mode when starting wpa_supplicant; set interface down when exiting 1096 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both 1097 ipw2100 and ipw2200; please note that this also changed the 1098 configuration variable in .config to CONFIG_DRIVER_IPW 1099 1100 2005-01-24 - v0.3.6 1101 * fixed a busy loop introduced in v0.3.5 for scan result processing 1102 when no matching AP is found 1103 1104 2005-01-23 - v0.3.5 1105 * added a workaround for an interoperability issue with a Cisco AP 1106 when using WPA2-PSK 1107 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as 1108 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow 1109 retransmission of dropped frames) 1110 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version 1111 (e.g., segfault when processing EAPOL-Key frames) 1112 * fixed EAP workaround and fast reauthentication configuration for 1113 RSN pre-authentication; previously these were disabled and 1114 pre-authentication would fail if the used authentication server 1115 requires EAP workarounds 1116 * added support for blacklisting APs that fail or timeout 1117 authentication in ap_scan=1 mode so that all APs are tried in cases 1118 where the ones with strongest signal level are failing authentication 1119 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS 1120 authentication attempt 1121 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded 1122 in the previous authentication (previously, only Phase 1 success was 1123 verified) 1124 1125 2005-01-09 - v0.3.4 1126 * added preliminary support for IBSS (ad-hoc) mode configuration 1127 (mode=1 in network block); this included a new key_mgmt mode 1128 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no 1129 key management; see wpa_supplicant.conf for more details and an 1130 example on how to configure this (note: this is currently implemented 1131 only for driver_hostapd.c, but the changes should be trivial to add 1132 in associate() handler for other drivers, too (assuming the driver 1133 supports WPA-None) 1134 * added preliminary port for native Windows (i.e., no cygwin) using 1135 mingw 1136 1137 2005-01-02 - v0.3.3 1138 * added optional support for GNU Readline and History Libraries for 1139 wpa_cli (CONFIG_READLINE) 1140 * cleaned up EAP state machine <-> method interface and number of 1141 small problems with error case processing not terminating on 1142 EAP-Failure but waiting for timeout 1143 * added couple of workarounds for interoperability issues with a 1144 Cisco AP when using WPA2 1145 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt); 1146 Note: This requires a patch for openssl to add support for TLS 1147 extensions and number of workarounds for operations without 1148 certificates. Proof of concept type of experimental patch is 1149 included in openssl-tls-extensions.patch. 1150 1151 2004-12-19 - v0.3.2 1152 * fixed private key loading for cases where passphrase is not set 1153 * fixed Windows/cygwin L2 packet handler freeing; previous version 1154 could cause a segfault when RSN pre-authentication was completed 1155 * added support for PMKSA caching with drivers that generate RSN IEs 1156 (e.g., NDIS); currently, this is only implemented in driver_ndis.c, 1157 but similar code can be easily added to driver_ndiswrapper.c once 1158 ndiswrapper gets full support for RSN PMKSA caching 1159 * improved recovery from PMKID mismatches by requesting full EAP 1160 authentication in case of failed PMKSA caching attempt 1161 * driver_ndis: added support for NDIS NdisMIncidateStatus() events 1162 (this requires that ndis_events is ran while wpa_supplicant is 1163 running) 1164 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys 1165 * added support for driver interfaces to replace the interface name 1166 based on driver/OS specific mapping, e.g., in case of driver_ndis, 1167 this allows the beginning of the adapter description to be used as 1168 the interface name 1169 * added support for CR+LF (Windows-style) line ends in configuration 1170 file 1171 * driver_ndis: enable radio before starting scanning, disable radio 1172 when exiting 1173 * modified association event handler to set portEnabled = FALSE before 1174 clearing port Valid in order to reset EAP state machine and avoid 1175 problems with new authentication getting ignored because of state 1176 machines ending up in AUTHENTICATED/SUCCESS state based on old 1177 information 1178 * added support for driver events to add PMKID candidates in order to 1179 allow drivers to give priority to most likely roaming candidates 1180 * driver_hostap: moved PrivacyInvoked configuration to associate() 1181 function so that this will not be set for plaintext connections 1182 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver 1183 interface can distinguish plaintext and IEEE 802.1X (no WPA) 1184 authentication 1185 * fixed static WEP key configuration to use broadcast/default type for 1186 all keys (previously, the default TX key was configured as pairwise/ 1187 unicast key) 1188 * driver_ndis: added legacy WPA capability detection for non-WPA2 1189 drivers 1190 * added support for setting static WEP keys for IEEE 802.1X without 1191 dynamic WEP keying (eapol_flags=0) 1192 1193 2004-12-12 - v0.3.1 1194 * added support for reading PKCS#12 (PFX) files (as a replacement for 1195 PEM/DER) to get certificate and private key (CONFIG_PKCS12) 1196 * fixed compilation with CONFIG_PCSC=y 1197 * added new ap_scan mode, ap_scan=2, for drivers that take care of 1198 association, but need to be configured with security policy and SSID, 1199 e.g., ndiswrapper and NDIS driver; this mode should allow such 1200 drivers to work with hidden SSIDs and optimized roaming; when 1201 ap_scan=2 is used, only the first network block in the configuration 1202 file is used and this configuration should have explicit security 1203 policy (i.e., only one option in the lists) for key_mgmt, pairwise, 1204 group, proto variables 1205 * added experimental port of wpa_supplicant for Windows 1206 - driver_ndis.c driver interface (NDIS OIDs) 1207 - currently, this requires cygwin and WinPcap 1208 - small utility, win_if_list, can be used to get interface name 1209 * control interface can now be removed at build time; add 1210 CONFIG_CTRL_IFACE=y to .config to maintain old functionality 1211 * optional Xsupplicant interface can now be removed at build time; 1212 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back) 1213 * added auth_alg to driver interface associate() parameters to make it 1214 easier for drivers to configure authentication algorithm as part of 1215 the association 1216 1217 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases) 1218 * driver_broadcom: added new driver interface for Broadcom wl.o driver 1219 (a generic driver for Broadcom IEEE 802.11a/g cards) 1220 * wpa_cli: fixed parsing of -p <path> command line argument 1221 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS 1222 ACK, not tunneled EAP-Success (of which only the first byte was 1223 actually send due to a bug in previous code); this seems to 1224 interoperate with most RADIUS servers that implements PEAPv1 1225 * PEAPv1: added support for terminating PEAP authentication on tunneled 1226 EAP-Success message; this can be configured by adding 1227 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf 1228 (some RADIUS servers require this whereas others require a tunneled 1229 reply 1230 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to 1231 the old label for key derivation; previously, the default was 1, 1232 but it looks like most existing PEAPv1 implementations use the old 1233 label which is thus more suitable default option 1234 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt) 1235 * fixed parsing of wep_tx_keyidx 1236 * added support for configuring list of allowed Phase 2 EAP types 1237 (for both EAP-PEAP and EAP-TTLS) instead of only one type 1238 * added support for configuring IEEE 802.11 authentication algorithm 1239 (auth_alg; mainly for using Shared Key authentication with static 1240 WEP keys) 1241 * added support for EAP-AKA (with UMTS SIM) 1242 * fixed couple of errors in PCSC handling that could have caused 1243 random-looking errors for EAP-SIM 1244 * added support for EAP-SIM pseudonyms and fast re-authentication 1245 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS 1246 session resumption) 1247 * added support for EAP-SIM with two challanges 1248 (phase1="sim_min_num_chal=3" can be used to require three challenges) 1249 * added support for configuring DH/DSA parameters for an ephemeral DH 1250 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters 1251 dh_file and dh_file2 (phase 2); this adds support for using DSA keys 1252 and optional DH key exchange to achieve forward secracy with RSA keys 1253 * added support for matching subject of the authentication server 1254 certificate with a substring when using EAP-TLS/PEAP/TTLS; new 1255 configuration variables subject_match and subject_match2 1256 * changed SSID configuration in driver_wext.c (used by many driver 1257 interfaces) to use ssid_len+1 as the length for SSID since some Linux 1258 drivers expect this 1259 * fixed couple of unaligned reads in scan result parsing to fix WPA 1260 connection on some platforms (e.g., ARM) 1261 * added driver interface for Intel ipw2100 driver 1262 * added support for LEAP with WPA 1263 * added support for larger scan results report (old limit was 4 kB of 1264 data, i.e., about 35 or so APs) when using Linux wireless extensions 1265 v17 or newer 1266 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start 1267 only if there is a PMKSA cache entry for the current AP 1268 * fixed error handling for case where reading of scan results fails: 1269 must schedule a new scan or wpa_supplicant will remain waiting 1270 forever 1271 * changed debug output to remove shared password/key material by 1272 default; all key information can be included with -K command line 1273 argument to match the previous behavior 1274 * added support for timestamping debug log messages (disabled by 1275 default, can be enabled with -t command line argument) 1276 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104 1277 if keys are not configured to be used; this fixes IEEE 802.1X mode 1278 with drivers that use this information to configure whether Privacy 1279 bit can be in Beacon frames (e.g., ndiswrapper) 1280 * avoid clearing driver keys if no keys have been configured since last 1281 key clear request; this seems to improve reliability of group key 1282 handshake for ndiswrapper & NDIS driver which seems to be suffering 1283 of some kind of timing issue when the keys are cleared again after 1284 association 1285 * changed driver interface API: 1286 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which 1287 version is being used (now, this is set to 2; previously, it was 1288 not defined) 1289 - pass pointer to private data structure to all calls 1290 - the new API is not backwards compatible; all in-tree driver 1291 interfaces has been converted to the new API 1292 * added support for controlling multiple interfaces (radios) per 1293 wpa_supplicant process; each interface needs to be listed on the 1294 command line (-c, -i, -D arguments) with -N as a separator 1295 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi) 1296 * added a workaround for EAP servers that incorrectly use same Id for 1297 sequential EAP packets 1298 * changed libpcap/libdnet configuration to use .config variable, 1299 CONFIG_DNET_PCAP, instead of requiring Makefile modification 1300 * improved downgrade attack detection in IE verification of msg 3/4: 1301 verify both WPA and RSN IEs, if present, not only the selected one; 1302 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or 1303 Probe Response frame, and RSN is enabled in wpa_supplicant 1304 configuration 1305 * fixed WPA msg 3/4 processing to allow Key Data field contain other 1306 IEs than just one WPA IE 1307 * added support for FreeBSD and driver interface for the BSD net80211 1308 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the 1309 required kernel mods have not yet been committed 1310 * made EAP workarounds configurable; enabled by default, can be 1311 disabled with network block option eap_workaround=0 1312 1313 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases) 1314 * resolved couple of interoperability issues with EAP-PEAPv1 and 1315 Phase 2 (inner EAP) fragment reassembly 1316 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the 1317 AP is using non-zero key index for the unicast key and key index zero 1318 for the broadcast key 1319 * driver_hostap: fixed IEEE 802.1X WEP key updates and 1320 re-authentication by allowing unencrypted EAPOL frames when not using 1321 WPA 1322 * added a new driver interface, 'wext', which uses only standard, 1323 driver independent functionality in Linux wireless extensions; 1324 currently, this can be used only for non-WPA IEEE 802.1X mode, but 1325 eventually, this is to be extended to support full WPA/WPA2 once 1326 Linux wireless extensions get support for this 1327 * added support for mode in which the driver is responsible for AP 1328 scanning and selection; this is disabled by default and can be 1329 enabled with global ap_scan=0 variable in wpa_supplicant.conf; 1330 this mode can be used, e.g., with generic 'wext' driver interface to 1331 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver 1332 supporting wireless extensions. 1333 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g., 1334 operation with an AP that does not include SSID in the Beacon frames) 1335 * added support for new EAP authentication methods: 1336 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP 1337 * added support for asking one-time-passwords from frontends (e.g., 1338 wpa_cli); this 'otp' command works otherwise like 'password' command, 1339 but the password is used only once and the frontend will be asked for 1340 a new password whenever a request from authenticator requires a 1341 password; this can be used with both EAP-OTP and EAP-GTC 1342 * changed wpa_cli to automatically re-establish connection so that it 1343 does not need to be re-started when wpa_supplicant is terminated and 1344 started again 1345 * improved user data (identity/password/otp) requests through 1346 frontends: process pending EAPOL packets after getting new 1347 information so that full authentication does not need to be 1348 restarted; in addition, send pending requests again whenever a new 1349 frontend is attached 1350 * changed control frontends to use a new directory for socket files to 1351 make it easier for wpa_cli to automatically select between interfaces 1352 and to provide access control for the control interface; 1353 wpa_supplicant.conf: ctrl_interface is now a path 1354 (/var/run/wpa_supplicant is the recommended path) and 1355 ctrl_interface_group can be used to select which group gets access to 1356 the control interface; 1357 wpa_cli: by default, try to connect to the first interface available 1358 in /var/run/wpa_supplicant; this path can be overriden with -p option 1359 and an interface can be selected with -i option (i.e., in most common 1360 cases, wpa_cli does not need to get any arguments) 1361 * added support for LEAP 1362 * added driver interface for Linux ndiswrapper 1363 * added priority option for network blocks in the configuration file; 1364 this allows networks to be grouped based on priority (the scan 1365 results are searched for matches with network blocks in this order) 1366 1367 2004-06-20 - v0.2.3 1368 * sort scan results to improve AP selection 1369 * fixed control interface socket removal for some error cases 1370 * improved scan requesting and authentication timeout 1371 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and 1372 TLS processing 1373 * PEAP version can now be forced with phase1="peapver=<ver>" 1374 (mostly for testing; by default, the highest version supported by 1375 both the Supplicant and Authentication Server is selected 1376 automatically) 1377 * added support for madwifi driver (Atheros ar521x) 1378 * added a workaround for cases where AP sets Install Tx/Rx bit for 1379 WPA Group Key messages when pairwise keys are used (without this, 1380 the Group Key would be used for Tx and the AP would drop frames 1381 from the station) 1382 * added GSM SIM/USIM interface for GSM authentication algorithm for 1383 EAP-SIM; this requires pcsc-lite 1384 * added support for ATMEL AT76C5XXx driver 1385 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator 1386 does not include key data in the EAPOL-Key frame (i.e., part of 1387 EAP keying material is used as data encryption key) 1388 * added support for using plaintext and static WEP networks 1389 (key_mgmt=NONE) 1390 1391 2004-05-31 - v0.2.2 1392 * added support for new EAP authentication methods: 1393 EAP-TTLS/EAP-MD5-Challenge 1394 EAP-TTLS/EAP-GTC 1395 EAP-TTLS/EAP-MSCHAPv2 1396 EAP-TTLS/EAP-TLS 1397 EAP-TTLS/MSCHAPv2 1398 EAP-TTLS/MSCHAP 1399 EAP-TTLS/PAP 1400 EAP-TTLS/CHAP 1401 EAP-PEAP/TLS 1402 EAP-PEAP/GTC 1403 EAP-PEAP/MD5-Challenge 1404 EAP-GTC 1405 EAP-SIM (not yet complete; needs GSM/SIM authentication interface) 1406 * added support for anonymous identity (to be used when identity is 1407 sent in plaintext; real identity will be used within TLS protected 1408 tunnel (e.g., with EAP-TTLS) 1409 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli 1410 * added support for requesting identity and password information using 1411 control interface; in other words, the password for EAP-PEAP or 1412 EAP-TTLS does not need to be included in the configuration file since 1413 a frontand (e.g., wpa_cli) can ask it from the user 1414 * improved RSN pre-authentication to use a candidate list and process 1415 all candidates from each scan; not only one per scan 1416 * fixed RSN IE and WPA IE capabilities field parsing 1417 * ignore Tx bit in GTK IE when Pairwise keys are used 1418 * avoid making new scan requests during IEEE 802.1X negotiation 1419 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant 1420 with TLS support (this replaces the included implementation with 1421 library code to save about 8 kB since the library code is needed 1422 anyway for TLS) 1423 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support 1424 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config) 1425 1426 2004-05-06 - v0.2.1 1427 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1) 1428 Supplicant 1429 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1] 1430 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf] 1431 - EAP-MD5 (cannot be used with WPA-RADIUS) 1432 [draft-ietf-eap-rfc2284bis-09.txt] 1433 - EAP-TLS [RFC 2716] 1434 - EAP-MSCHAPv2 (currently used only with EAP-PEAP) 1435 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt] 1436 [draft-kamath-pppext-eap-mschapv2-00.txt] 1437 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by 1438 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey) 1439 - new configuration file options: eap, identity, password, ca_cert, 1440 client_cert, privatekey, private_key_passwd 1441 - Xsupplicant is not required anymore, but it can be used by 1442 disabling the internal IEEE 802.1X Supplicant with -e command line 1443 option 1444 - this code is not included in the default build; Makefile need to 1445 be edited for this (uncomment lines for selected functionality) 1446 - EAP-TLS and EAP-PEAP require openssl libraries 1447 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..) 1448 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys 1449 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X 1450 EAPOL-Key frames instead of WPA key handshakes) 1451 * added support for IEEE 802.11i/RSN (WPA2) 1452 - improved PTK Key Handshake 1453 - PMKSA caching, pre-authentication 1454 * fixed wpa_supplicant to ignore possible extra data after WPA 1455 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using 1456 TPTK' error from message 3 of 4-Way Handshake in case the AP 1457 includes extra data after the EAPOL-Key) 1458 * added interface for external programs (frontends) to control 1459 wpa_supplicant 1460 - CLI example (wpa_cli) with interactive mode and command line 1461 mode 1462 - replaced SIGUSR1 status/statistics with the new control interface 1463 * made some feature compile time configurable 1464 - .config file for make 1465 - driver interfaces (hostap, hermes, ..) 1466 - EAPOL/EAP functions 1467 1468 2004-02-15 - v0.2.0 1469 * Initial version of wpa_supplicant 1470
