1ChangeLog for wpa_supplicant 2 32010-04-18 - v0.7.2 4 * nl80211: fixed number of issues with roaming 5 * avoid unnecessary roaming if multiple APs with similar signal 6 strength are present in scan results 7 * add TLS client events and server probing to ease design of 8 automatic detection of EAP parameters 9 * add option for server certificate matching (SHA256 hash of the 10 certificate) instead of trusted CA certificate configuration 11 * bsd: Cleaned up driver wrapper and added various low-level 12 configuration options 13 * wpa_gui-qt4: do not show too frequent WPS AP available events as 14 tray messages 15 * TNC: fixed issues with fragmentation 16 * EAP-TNC: add Flags field into fragment acknowledgement (needed to 17 interoperate with other implementations; may potentially breaks 18 compatibility with older wpa_supplicant/hostapd versions) 19 * wpa_cli: added option for using a separate process to receive event 20 messages to reduce latency in showing these 21 (CFLAGS += -DCONFIG_WPA_CLI_FORK=y in .config to enable this) 22 * maximum BSS table size can now be configured (bss_max_count) 23 * BSSes to be included in the BSS table can be filtered based on 24 configured SSIDs to save memory (filter_ssids) 25 * fix number of issues with IEEE 802.11r/FT; this version is not 26 backwards compatible with old versions 27 * nl80211: add support for IEEE 802.11r/FT protocol (both over-the-air 28 and over-the-DS) 29 * add freq_list network configuration parameter to allow the AP 30 selection to filter out entries based on the operating channel 31 * add signal strength change events for bgscan; this allows more 32 dynamic changes to background scanning interval based on changes in 33 the signal strength with the current AP; this improves roaming within 34 ESS quite a bit, e.g., with bgscan="simple:30:-45:300" in the network 35 configuration block to request background scans less frequently when 36 signal strength remains good and to automatically trigger background 37 scans whenever signal strength drops noticeably 38 (this is currently only available with nl80211) 39 * add BSSID and reason code (if available) to disconnect event messages 40 * wpa_gui-qt4: more complete support for translating the GUI with 41 linguist and add German translation 42 * fix DH padding with internal crypto code (mainly, for WPS) 43 * do not trigger initial scan automatically anymore if there are no 44 enabled networks 45 462010-01-16 - v0.7.1 47 * cleaned up driver wrapper API (struct wpa_driver_ops); the new API 48 is not fully backwards compatible, so out-of-tree driver wrappers 49 will need modifications 50 * cleaned up various module interfaces 51 * merge hostapd and wpa_supplicant developers' documentation into a 52 single document 53 * nl80211: use explicit deauthentication to clear cfg80211 state to 54 avoid issues when roaming between APs 55 * dbus: major design changes in the new D-Bus API 56 (fi.w1.wpa_supplicant1) 57 * nl80211: added support for IBSS networks 58 * added internal debugging mechanism with backtrace support and memory 59 allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y) 60 * added WPS ER unsubscription command to more cleanly unregister from 61 receiving UPnP events when ER is terminated 62 * cleaned up AP mode operations to avoid need for virtual driver_ops 63 wrapper 64 * added BSS table to maintain more complete scan result information 65 over multiple scans (that may include only partial results) 66 * wpa_gui-qt4: update Peers dialog information more dynamically while 67 the dialog is kept open 68 * fixed PKCS#12 use with OpenSSL 1.0.0 69 * driver_wext: Added cfg80211-specific optimization to avoid some 70 unnecessary scans and to speed up association 71 722009-11-21 - v0.7.0 73 * increased wpa_cli ping interval to 5 seconds and made this 74 configurable with a new command line options (-G<seconds>) 75 * fixed scan buffer processing with WEXT to handle up to 65535 76 byte result buffer (previously, limited to 32768 bytes) 77 * allow multiple driver wrappers to be specified on command line 78 (e.g., -Dnl80211,wext); the first one that is able to initialize the 79 interface will be used 80 * added support for multiple SSIDs per scan request to optimize 81 scan_ssid=1 operations in ap_scan=1 mode (i.e., search for hidden 82 SSIDs); this requires driver support and can currently be used only 83 with nl80211 84 * added support for WPS USBA out-of-band mechanism with USB Flash 85 Drives (UFD) (CONFIG_WPS_UFD=y) 86 * driver_ndis: add PAE group address to the multicast address list to 87 fix wired IEEE 802.1X authentication 88 * fixed IEEE 802.11r key derivation function to match with the standard 89 (note: this breaks interoperability with previous version) [Bug 303] 90 * added better support for drivers that allow separate authentication 91 and association commands (e.g., mac80211-based Linux drivers with 92 nl80211; SME in wpa_supplicant); this allows over-the-air FT protocol 93 to be used (IEEE 802.11r) 94 * fixed SHA-256 based key derivation function to match with the 95 standard when using CCMP (for IEEE 802.11r and IEEE 802.11w) 96 (note: this breaks interoperability with previous version) [Bug 307] 97 * use shared driver wrapper files with hostapd 98 * added AP mode functionality (CONFIG_AP=y) with mode=2 in the network 99 block; this can be used for open and WPA2-Personal networks 100 (optionally, with WPS); this links in parts of hostapd functionality 101 into wpa_supplicant 102 * wpa_gui-qt4: added new Peers dialog to show information about peers 103 (other devices, including APs and stations, etc. in the neighborhood) 104 * added support for WPS External Registrar functionality (configure APs 105 and enroll new devices); can be used with wpa_gui-qt4 Peers dialog 106 and wpa_cli commands wps_er_start, wps_er_stop, wps_er_pin, 107 wps_er_pbc, wps_er_learn 108 (this can also be used with a new 'none' driver wrapper if no 109 wireless device or IEEE 802.1X on wired is needed) 110 * driver_nl80211: multiple updates to provide support for new Linux 111 nl80211/mac80211 functionality 112 * updated management frame protection to use IEEE Std 802.11w-2009 113 * fixed number of small WPS issues and added workarounds to 114 interoperate with common deployed broken implementations 115 * added support for NFC out-of-band mechanism with WPS 116 * driver_ndis: fixed wired IEEE 802.1X authentication with PAE group 117 address frames 118 * added preliminary support for IEEE 802.11r RIC processing 119 * added support for specifying subset of enabled frequencies to scan 120 (scan_freq option in the network configuration block); this can speed 121 up scanning process considerably if it is known that only a small 122 subset of channels is actually used in the network (this is currently 123 supported only with -Dnl80211) 124 * added a workaround for race condition between receiving the 125 association event and the following EAPOL-Key 126 * added background scan and roaming infrastructure to allow 127 network-specific optimizations to be used to improve roaming within 128 an ESS (same SSID) 129 * added new DBus interface (fi.w1.wpa_supplicant1) 130 1312009-01-06 - v0.6.7 132 * added support for Wi-Fi Protected Setup (WPS) 133 (wpa_supplicant can now be configured to act as a WPS Enrollee to 134 enroll credentials for a network using PIN and PBC methods; in 135 addition, wpa_supplicant can act as a wireless WPS Registrar to 136 configure an AP); WPS support can be enabled by adding CONFIG_WPS=y 137 into .config and setting the runtime configuration variables in 138 wpa_supplicant.conf (see WPS section in the example configuration 139 file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to 140 manage WPS negotiation; see README-WPS for more details 141 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf) 142 * added support for using driver_test over UDP socket 143 * fixed PEAPv0 Cryptobinding interoperability issue with Windows Server 144 2008 NPS; optional cryptobinding is now enabled (again) by default 145 * fixed PSK editing in wpa_gui 146 * changed EAP-GPSK to use the IANA assigned EAP method type 51 147 * added a Windows installer that includes WinPcap and all the needed 148 DLLs; in addition, it set up the registry automatically so that user 149 will only need start wpa_gui to get prompted to start the wpasvc 150 servide and add a new interface if needed through wpa_gui dialog 151 * updated management frame protection to use IEEE 802.11w/D7.0 152 1532008-11-23 - v0.6.6 154 * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA 155 (can be used to simulate test SIM/USIM card with a known private key; 156 enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config 157 and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration) 158 * added a new network configuration option, wpa_ptk_rekey, that can be 159 used to enforce frequent PTK rekeying, e.g., to mitigate some attacks 160 against TKIP deficiencies 161 * added an optional mitigation mechanism for certain attacks against 162 TKIP by delaying Michael MIC error reports by a random amount of time 163 between 0 and 60 seconds; this can be enabled with a build option 164 CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config 165 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits, 166 not bytes 167 * updated OpenSSL code for EAP-FAST to use an updated version of the 168 session ticket overriding API that was included into the upstream 169 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is 170 needed with that version anymore) 171 * updated userspace MLME instructions to match with the current Linux 172 mac80211 implementation; please also note that this can only be used 173 with driver_nl80211.c (the old code from driver_wext.c was removed) 174 * added support (Linux only) for RoboSwitch chipsets (often found in 175 consumer grade routers); driver interface 'roboswitch' 176 * fixed canceling of PMKSA caching when using drivers that generate 177 RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know 178 about 179 1802008-11-01 - v0.6.5 181 * added support for SHA-256 as X.509 certificate digest when using the 182 internal X.509/TLSv1 implementation 183 * updated management frame protection to use IEEE 802.11w/D6.0 184 * added support for using SHA256-based stronger key derivation for WPA2 185 (IEEE 802.11w) 186 * fixed FT (IEEE 802.11r) authentication after a failed association to 187 use correct FTIE 188 * added support for configuring Phase 2 (inner/tunneled) authentication 189 method with wpa_gui-qt4 190 1912008-08-10 - v0.6.4 192 * added support for EAP Sequences in EAP-FAST Phase 2 193 * added support for using TNC with EAP-FAST 194 * added driver_ps3 for the PS3 Linux wireless driver 195 * added support for optional cryptobinding with PEAPv0 196 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to 197 allow fallback to full handshake if server rejects PAC-Opaque 198 * added fragmentation support for EAP-TNC 199 * added support for parsing PKCS #8 formatted private keys into the 200 internal TLS implementation (both PKCS #1 RSA key and PKCS #8 201 encapsulated RSA key can now be used) 202 * added option of using faster, but larger, routines in the internal 203 LibTomMath (for internal TLS implementation) to speed up DH and RSA 204 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y) 205 * fixed race condition between disassociation event and group key 206 handshake to avoid getting stuck in incorrect state [Bug 261] 207 * fixed opportunistic key caching (proactive_key_caching) 208 2092008-02-22 - v0.6.3 210 * removed 'nai' and 'eappsk' network configuration variables that were 211 previously used for configuring user identity and key for EAP-PSK, 212 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the 213 replacement for 'nai' (if old configuration used a separate 214 'identity' value, that would now be configured as 215 'anonymous_identity'). 'password' field is now used as the 216 replacement for 'eappsk' (it can also be set using hexstring to 217 present random binary data) 218 * removed '-w' command line parameter (wait for interface to be added, 219 if needed); cleaner way of handling this functionality is to use an 220 external mechanism (e.g., hotplug scripts) that start wpa_supplicant 221 when an interface is added 222 * updated FT support to use the latest draft, IEEE 802.11r/D9.0 223 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for 224 indicating when new scan results become available 225 * added new ctrl_iface command, BSS, to allow scan results to be 226 fetched without hitting the message size limits (this command 227 can be used to iterate through the scan results one BSS at the time) 228 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION 229 attributes in EAP-SIM Start/Response when using fast reauthentication 230 * fixed EAPOL not to end up in infinite loop when processing dynamic 231 WEP keys with IEEE 802.1X 232 * fixed problems in getting NDIS events from WMI on Windows 2000 233 2342008-01-01 - v0.6.2 235 * added support for Makefile builds to include debug-log-to-a-file 236 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line) 237 * fixed EAP-SIM and EAP-AKA message parser to validate attribute 238 lengths properly to avoid potential crash caused by invalid messages 239 * added data structure for storing allocated buffers (struct wpabuf); 240 this does not affect wpa_supplicant usage, but many of the APIs 241 changed and various interfaces (e.g., EAP) is not compatible with old 242 versions 243 * added support for protecting EAP-AKA/Identity messages with 244 AT_CHECKCODE (optional feature in RFC 4187) 245 * added support for protected result indication with AT_RESULT_IND for 246 EAP-SIM and EAP-AKA (phase1="result_ind=1") 247 * added driver_wext workaround for race condition between scanning and 248 association with drivers that take very long time to scan all 249 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now 250 using a longer hardcoded timeout for the scan if the driver supports 251 notifications for scan completion (SIOCGIWSCAN event); this helps, 252 e.g., in cases where wpa_supplicant and madwifi driver ended up in 253 loop where the driver did not even try to associate 254 * stop EAPOL timer tick when no timers are in use in order to reduce 255 power consumption (no need to wake up the process once per second) 256 [Bug 237] 257 * added support for privilege separation (run only minimal part of 258 wpa_supplicant functionality as root and rest as unprivileged, 259 non-root process); see 'Privilege separation' in README for details; 260 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y 261 in .config 262 * changed scan results data structure to include all information 263 elements to make it easier to support new IEs; old get_scan_result() 264 driver_ops is still supported for backwards compatibility (results 265 are converted internally to the new format), but all drivers should 266 start using the new get_scan_results2() to make them more likely to 267 work with new features 268 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4 269 application, i.e., it does not require Qt3Support anymore; Windows 270 binary of wpa_gui.exe is now from this directory and only requires 271 QtCore4.dll and QtGui4.dll libraries 272 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs 273 available as a separate package to make wpa_gui installation easier: 274 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip 275 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt); 276 only shared key/password authentication is supported in this version 277 2782007-11-24 - v0.6.1 279 * added support for configuring password as NtPasswordHash 280 (16-byte MD4 hash of password) in hash:<32 hex digits> format 281 * added support for fallback from abbreviated TLS handshake to 282 full handshake when using EAP-FAST (e.g., due to an expired 283 PAC-Opaque) 284 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 285 draft (draft-ietf-emu-eap-gpsk-07.txt) 286 * added support for drivers that take care of RSN 4-way handshake 287 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and 288 WPA_ALG_PMK in set_key) 289 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in 290 .config); this version supports only ap_scan=2 mode and allow the 291 driver to take care of the 4-way handshake 292 * fixed a buffer overflow in parsing TSF from scan results when using 293 driver_wext.c with a driver that includes the TSF (e.g., iwl4965) 294 [Bug 232] 295 * updated FT support to use the latest draft, IEEE 802.11r/D8.0 296 * fixed an integer overflow issue in the ASN.1 parser used by the 297 (experimental) internal TLS implementation to avoid a potential 298 buffer read overflow 299 * fixed a race condition with -W option (wait for a control interface 300 monitor before starting) that could have caused the first messages to 301 be lost 302 * added support for processing TNCC-TNCS-Messages to report 303 recommendation (allow/none/isolate) when using TNC [Bug 243] 304 3052007-05-28 - v0.6.0 306 * added network configuration parameter 'frequency' for setting 307 initial channel for IBSS (adhoc) networks 308 * added experimental IEEE 802.11r/D6.0 support 309 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48 310 * updated EAP-PSK to use the IANA-allocated EAP type 47 311 * fixed EAP-PAX key derivation 312 * fixed EAP-PSK bit ordering of the Flags field 313 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in 314 tunnelled identity request (previously, the identifier from the outer 315 method was used, not the tunnelled identifier which could be 316 different) 317 * added support for fragmentation of outer TLS packets during Phase 2 318 of EAP-PEAP/TTLS/FAST 319 * fixed EAP-TTLS AVP parser processing for too short AVP lengths 320 * added support for EAP-FAST authentication with inner methods that 321 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported 322 for PAC provisioning) 323 * added support for authenticated EAP-FAST provisioning 324 * added support for configuring maximum number of EAP-FAST PACs to 325 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string) 326 * added support for storing EAP-FAST PACs in binary format 327 (fast_pac_format=binary in phase1 string) 328 * fixed dbus ctrl_iface to validate message interface before 329 dispatching to avoid a possible segfault [Bug 190] 330 * fixed PeerKey key derivation to use the correct PRF label 331 * updated Windows binary build to link against OpenSSL 0.9.8d and 332 added support for EAP-FAST 333 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 334 draft (draft-ietf-emu-eap-gpsk-04.txt) 335 * fixed EAP-AKA Notification processing to allow Notification to be 336 processed after AKA Challenge response has been sent 337 * updated to use IEEE 802.11w/D2.0 for management frame protection 338 (still experimental) 339 * fixed EAP-TTLS implementation not to crash on use of freed memory 340 if TLS library initialization fails 341 * added support for EAP-TNC (Trusted Network Connect) 342 (this version implements the EAP-TNC method and EAP-TTLS changes 343 needed to run two methods in sequence (IF-T) and the IF-IMC and 344 IF-TNCCS interfaces from TNCC) 345 3462006-11-24 - v0.5.6 347 * added experimental, integrated TLSv1 client implementation with the 348 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by 349 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in 350 .config); this can be useful, e.g., if the target system does not 351 have a suitable TLS library and a minimal code size is required 352 (total size of this internal TLS/crypto code is bit under 50 kB on 353 x86 and the crypto code is shared by rest of the supplicant so some 354 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB) 355 * removed STAKey handshake since PeerKey handshake has replaced it in 356 IEEE 802.11ma and there are no known deployments of STAKey 357 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 358 draft (draft-ietf-emu-eap-gpsk-01.txt) 359 * added preliminary implementation of IEEE 802.11w/D1.0 (management 360 frame protection) 361 (Note: this requires driver support to work properly.) 362 (Note2: IEEE 802.11w is an unapproved draft and subject to change.) 363 * fixed Windows named pipes ctrl_iface to not stop listening for 364 commands if client program opens a named pipe and closes it 365 immediately without sending a command 366 * fixed USIM PIN status determination for the case that PIN is not 367 needed (this allows EAP-AKA to be used with USIM cards that do not 368 use PIN) 369 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to 370 be used with cards that do not support file selection based on 371 partial AID 372 * added support for matching the subjectAltName of the authentication 373 server certificate against multiple name components (e.g., 374 altsubject_match="DNS:server.example.com;DNS:server2.example.com") 375 * fixed EAP-SIM/AKA key derivation for re-authentication case (only 376 affects IEEE 802.1X with dynamic WEP keys) 377 * changed ctrl_iface network configuration 'get' operations to not 378 return password/key material; if these fields are requested, "*" 379 will be returned if the password/key is set, but the value of the 380 parameter is not exposed 381 3822006-08-27 - v0.5.5 383 * added support for building Windows version with UNICODE defined 384 (wide-char functions) 385 * driver_ndis: fixed static WEP configuration to avoid race condition 386 issues with some NDIS drivers between association and setting WEP 387 keys 388 * driver_ndis: added validation for IELength value in scan results to 389 avoid crashes when using buggy NDIS drivers [Bug 165] 390 * fixed Release|Win32 target in the Visual Studio project files 391 (previously, only Debug|Win32 target was set properly) 392 * changed control interface API call wpa_ctrl_pending() to allow it to 393 return -1 on error (e.g., connection lost); control interface clients 394 will need to make sure that they verify that the value is indeed >0 395 when determining whether there are pending messages 396 * added an alternative control interface backend for Windows targets: 397 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default 398 control interface mechanism for Windows builds (previously, UDP to 399 localhost was used) 400 * changed ctrl_interface configuration for UNIX domain sockets: 401 - deprecated ctrl_interface_group variable (it may be removed in 402 future versions) 403 - allow both directory and group be configured with ctrl_interface 404 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel 405 - ctrl_interface=/var/run/wpa_supplicant is still supported for the 406 case when group is not changed 407 * added support for controlling more than one interface per process in 408 Windows version 409 * added a workaround for a case where the AP is using unknown address 410 (e.g., MAC address of the wired interface) as the source address for 411 EAPOL-Key frames; previously, that source address was used as the 412 destination for EAPOL-Key frames and in key derivation; now, BSSID is 413 used even if the source address does not match with it 414 (this resolves an interoperability issue with Thomson SpeedTouch 580) 415 * added a workaround for UDP-based control interface (which was used in 416 Windows builds before this release) to prevent packets with forged 417 addresses from being accepted as local control requests 418 * removed ndis_events.cpp and possibility of using external 419 ndis_events.exe; C version (ndis_events.c) is fully functional and 420 there is no desire to maintain two separate versions of this 421 implementation 422 * ndis_events: Changed NDIS event notification design to use WMI to 423 learn the adapter description through Win32_PnPEntity class; this 424 should fix some cases where the adapter name was not recognized 425 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500 426 USB) [Bug 113] 427 * fixed selection of the first network in ap_scan=2 mode; previously, 428 wpa_supplicant could get stuck in SCANNING state when only the first 429 network for enabled (e.g., after 'wpa_cli select_network 0') 430 * winsvc: added support for configuring ctrl_interface parameters in 431 registry (ctrl_interface string value in 432 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is 433 required to enable control interface (previously, this was hardcoded 434 to be enabled) 435 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4 436 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format 437 4382006-06-20 - v0.5.4 439 * fixed build with CONFIG_STAKEY=y [Bug 143] 440 * added support for doing MLME (IEEE 802.11 management frame 441 processing) in wpa_supplicant when using Devicescape IEEE 802.11 442 stack (wireless-dev.git tree) 443 * added a new network block configuration option, fragment_size, to 444 configure the maximum EAP fragment size 445 * driver_ndis: Disable WZC automatically for the selected interface to 446 avoid conflicts with two programs trying to control the radio; WZC 447 will be re-enabled (if it was enabled originally) when wpa_supplicant 448 is terminated 449 * added an experimental TLSv1 client implementation 450 (CONFIG_TLS=internal) that can be used instead of an external TLS 451 library, e.g., to reduce total size requirement on systems that do 452 not include any TLS library by default (this is not yet complete; 453 basic functionality is there, but certificate validation is not yet 454 included) 455 * added PeerKey handshake implementation for IEEE 802.11e 456 direct link setup (DLS) to replace STAKey handshake 457 * fixed WPA PSK update through ctrl_iface for the case where the old 458 PSK was derived from an ASCII passphrase and the new PSK is set as 459 a raw PSK (hex string) 460 * added new configuration option for identifying which network block 461 was used (id_str in wpa_supplicant.conf; included on 462 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental 463 variable in wpa_cli action scripts; in addition WPA_ID variable is 464 set to the current unique identifier that wpa_supplicant assigned 465 automatically for the network and that can be used with 466 GET_NETWORK/SET_NETWORK ctrl_iface commands) 467 * wpa_cli action script is now called only when the connect/disconnect 468 status changes or when associating with a different network 469 * fixed configuration parser not to remove CCMP from group cipher list 470 if WPA-None (adhoc) is used (pairwise=NONE in that case) 471 * fixed integrated NDIS events processing not to hang the process due 472 to a missed change in eloop_win.c API in v0.5.3 [Bug 155] 473 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK, 474 draft-clancy-emu-eap-shared-secret-00.txt) 475 * added Microsoft Visual Studio 2005 solution and project files for 476 build wpa_supplicant for Windows (see vs2005 subdirectory) 477 * eloop_win: fixed unregistration of Windows events 478 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet 479 at the end of RSN pre-authentication and added unregistration of 480 a Windows event to avoid getting eloop_win stuck with an invalid 481 handle 482 * driver_ndis: added support for selecting AP based on BSSID 483 * added new environmental variable for wpa_cli action scripts: 484 WPA_CTRL_DIR is the current control interface directory 485 * driver_ndis: added support for using NDISUIO instead of WinPcap for 486 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new 487 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build 488 wpa_supplicant without requiring WinPcap; note that using NDISUIO 489 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows 490 only one application to open the device 491 * changed NDIS driver naming to only include device GUID, e.g., 492 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap 493 specific \Device\NPF_ prefix before the GUID; the prefix is still 494 allowed for backwards compatibility, but it is not required anymore 495 when specifying the interface 496 * driver_ndis: re-initialize driver interface is the adapter is removed 497 and re-inserted [Bug 159] 498 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on 499 big endian hosts [Bug 146] 500 5012006-04-27 - v0.5.3 502 * fixed EAP-GTC response to include correct user identity when run as 503 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2) 504 * driver_ndis: Fixed encryption mode configuration for unencrypted 505 networks (some NDIS drivers ignored this, but others, e.g., Broadcom, 506 refused to associate with open networks) [Bug 106] 507 * driver_ndis: use BSSID OID polling to detect when IBSS network is 508 formed even when ndis_events code is included since some NDIS drivers 509 do not generate media connect events in IBSS mode 510 * config_winreg: allow global ctrl_interface parameter to be configured 511 in Windows registry 512 * config_winreg: added support for saving configuration data into 513 Windows registry 514 * added support for controlling network device operational state 515 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see 516 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client 517 that can use this information) 518 * driver_wext: added support for WE-21 change to SSID configuration 519 * driver_wext: fixed privacy configuration for static WEP keys mode 520 [Bug 140] 521 * added an optional driver_ops callback for MLME-SETPROTECTION.request 522 primitive 523 * added support for EAP-SAKE (no EAP method number allocated yet, so 524 this is using the same experimental type 255 as EAP-PSK) 525 * added support for dynamically loading EAP methods (.so files) instead 526 of requiring them to be statically linked in; this is disabled by 527 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information 528 on how to use this) 529 5302006-03-19 - v0.5.2 531 * do not try to use USIM APDUs when initializing PC/SC for SIM card 532 access for a network that has not enabled EAP-AKA 533 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in 534 v0.5.1 due to the new support for expanded EAP types) 535 * added support for generating EAP Expanded Nak 536 * try to fetch scan results once before requesting new scan when 537 starting up in ap_scan=1 mode (this can speed up initial association 538 a lot with, e.g., madwifi-ng driver) 539 * added support for receiving EAPOL frames from a Linux bridge 540 interface (-bbr0 on command line) 541 * fixed EAPOL re-authentication for sessions that used PMKSA caching 542 * changed EAP method registration to use a dynamic list of methods 543 instead of a static list generated at build time 544 * fixed PMKSA cache deinitialization not to use freed memory when 545 removing PMKSA entries 546 * fixed a memory leak in EAP-TTLS re-authentication 547 * reject WPA/WPA2 message 3/4 if it does not include any valid 548 WPA/RSN IE 549 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg 550 if the driver does not support SIOCSIWAUTH 551 5522006-01-29 - v0.5.1 553 * driver_test: added better support for multiple APs and STAs by using 554 a directory with sockets that include MAC address for each device in 555 the name (driver_param=test_dir=/tmp/test) 556 * added support for EAP expanded type (vendor specific EAP methods) 557 * added AP_SCAN command into ctrl_iface so that ap_scan configuration 558 option can be changed if needed 559 * wpa_cli/wpa_gui: skip non-socket files in control directory when 560 using UNIX domain sockets; this avoids selecting an incorrect 561 interface (e.g., a PID file could be in this directory, even though 562 use of this directory for something else than socket files is not 563 recommended) 564 * fixed TLS library deinitialization after RSN pre-authentication not 565 to disable TLS library for normal authentication 566 * driver_wext: Remove null-termination from SSID length if the driver 567 used it; some Linux drivers do this and they were causing problems in 568 wpa_supplicant not finding matching configuration block. This change 569 would break a case where the SSID actually ends in '\0', but that is 570 not likely to happen in real use. 571 * fixed PMKSA cache processing not to trigger deauthentication if the 572 current PMKSA cache entry is replaced with a valid new entry 573 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes 574 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or 575 ap_scan=2) 576 5772005-12-18 - v0.5.0 (beginning of 0.5.x development releases) 578 * added experimental STAKey handshake implementation for IEEE 802.11e 579 direct link setup (DLS); note: this is disabled by default in both 580 build and runtime configuration (can be enabled with CONFIG_STAKEY=y 581 and stakey=1) 582 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to 583 decrypt AT_ENCR_DATA attributes correctly 584 * fixed EAP-AKA to allow resynchronization within the same session 585 * made code closer to ANSI C89 standard to make it easier to port to 586 other C libraries and compilers 587 * started moving operating system or C library specific functions into 588 wrapper functions defined in os.h and implemented in os_*.c to make 589 code more portable 590 * wpa_supplicant can now be built with Microsoft Visual C++ 591 (e.g., with the freely available Toolkit 2003 version or Visual 592 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an 593 example makefile for nmake 594 * added support for using Windows registry for command line parameters 595 (CONFIG_MAIN=main_winsvc) and configuration data 596 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry 597 contents; this version can be run both as a Windows service and as a 598 normal application; 'wpasvc.exe app' to start as applicant, 599 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service, 600 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to 601 unregister a service 602 * made it possible to link ndis_events.exe functionality into 603 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED 604 * added better support for multiple control interface backends 605 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported 606 * fixed PC/SC code to use correct length for GSM AUTH command buffer 607 and to not use pioRecvPci with SCardTransmit() calls; these were not 608 causing visible problems with pcsc-lite, but Windows Winscard.dll 609 refused the previously used parameters; this fixes EAP-SIM and 610 EAP-AKA authentication using SIM/USIM card under Windows 611 * added new event loop implementation for Windows using 612 WaitForMultipleObject() instead of select() in order to allow waiting 613 for non-socket objects; this can be selected with 614 CONFIG_ELOOP=eloop_win in .config 615 * added support for selecting l2_packet implementation in .config 616 (CONFIG_L2_PACKET; following options are available now: linux, pcap, 617 winpcap, freebsd, none) 618 * added new l2_packet implementation for WinPcap 619 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to 620 reduce latency in EAPOL receive processing from about 100 ms to about 621 3 ms 622 * added support for EAP-FAST key derivation using other ciphers than 623 RC4-128-SHA for authentication and AES128-SHA for provisioning 624 * added support for configuring CA certificate as DER file and as a 625 configuration blob 626 * fixed private key configuration as configuration blob and added 627 support for using PKCS#12 as a blob 628 * tls_gnutls: added support for using PKCS#12 files; added support for 629 session resumption 630 * added support for loading trusted CA certificates from Windows 631 certificate store: ca_cert="cert_store://<name>", where <name> is 632 likely CA (Intermediate CA certificates) or ROOT (root certificates) 633 * added C version of ndis_events.cpp and made it possible to build this 634 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more 635 easily on cross-compilation builds 636 * added wpasvc.exe into Windows binary release; this is an alternative 637 version of wpa_supplicant.exe with configuration backend using 638 Windows registry and with the entry point designed to run as a 639 Windows service 640 * integrated ndis_events.exe functionality into wpa_supplicant.exe and 641 wpasvc.exe and removed this additional tool from the Windows binary 642 release since it is not needed anymore 643 * load winscard.dll functions dynamically when building with MinGW 644 since MinGW does not yet include winscard library 645 6462005-11-20 - v0.4.7 (beginning of 0.4.x stable releases) 647 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap 648 and WinPcap to receive frames sent to PAE group address 649 * disable EAP state machine when IEEE 802.1X authentication is not used 650 in order to get rid of bogus "EAP failed" messages 651 * fixed OpenSSL error reporting to go through all pending errors to 652 avoid confusing reports of old errors being reported at later point 653 during handshake 654 * fixed configuration file updating to not write empty variables 655 (e.g., proto or key_mgmt) that the file parser would not accept 656 * fixed ADD_NETWORK ctrl_iface command to use the same default values 657 for variables as empty network definitions read from config file 658 would get 659 * fixed EAP state machine to not discard EAP-Failure messages in many 660 cases (e.g., during TLS handshake) 661 * fixed a infinite loop in private key reading if the configured file 662 cannot be parsed successfully 663 * driver_madwifi: added support for madwifi-ng 664 * wpa_gui: do not display password/PSK field contents 665 * wpa_gui: added CA certificate configuration 666 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID 667 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if 668 the new AP is using different WPA/RSN IE 669 * use longer timeout for IEEE 802.11 association to avoid problems with 670 drivers that may take more than five second to associate 671 6722005-10-27 - v0.4.6 673 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in 674 RSN IE, but WPA IE would match with wpa_supplicant configuration 675 * added support for named configuration blobs in order to avoid having 676 to use file system for external files (e.g., certificates); 677 variables can be set to "blob://<blob name>" instead of file path to 678 use a named blob; supported fields: pac_file, client_cert, 679 private_key 680 * fixed RSN pre-authentication (it was broken in the clean up of WPA 681 state machine interface in v0.4.5) 682 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make 683 sure the driver configures broadcast decryption correctly 684 * added ca_path (and ca_path2) configuration variables that can be used 685 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the 686 system-wide trusted CA list 687 * added support for starting wpa_supplicant without a configuration 688 file (-C argument must be used to set ctrl_interface parameter for 689 this case; in addition, -p argument can be used to provide 690 driver_param; these new arguments can also be used with a 691 configuration to override the values from the configuration) 692 * added global control interface that can be optionally used for adding 693 and removing network interfaces dynamically (-g command line argument 694 for both wpa_supplicant and wpa_cli) without having to restart 695 wpa_supplicant process 696 * wpa_gui: 697 - try to save configuration whenever something is modified 698 - added WEP key configuration 699 - added possibility to edit the current network configuration 700 * driver_ndis: fixed driver polling not to increase frequency on each 701 received EAPOL frame due to incorrectly cancelled timeout 702 * added simple configuration file examples (in examples subdirectory) 703 * fixed driver_wext.c to filter wireless events based on ifindex to 704 avoid interfaces receiving events from other interfaces 705 * delay sending initial EAPOL-Start couple of seconds to speed up 706 authentication for the most common case of Authenticator starting 707 EAP authentication immediately after association 708 7092005-09-25 - v0.4.5 710 * added a workaround for clearing keys with ndiswrapper to allow 711 roaming from WPA enabled AP to plaintext one 712 * added docbook documentation (doc/docbook) that can be used to 713 generate, e.g., man pages 714 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for 715 PF_PACKET in order to prepare for network devices that do not use 716 Ethernet headers (e.g., network stack with native IEEE 802.11 frames) 717 * use receipt of EAPOL-Key frame as a lower layer success indication 718 for EAP state machine to allow recovery from dropped EAP-Success 719 frame 720 * cleaned up internal EAPOL frame processing by not including link 721 layer (Ethernet) header during WPA and EAPOL/EAP processing; this 722 header is added only when transmitted the frame; this makes it easier 723 to use wpa_supplicant on link layers that use different header than 724 Ethernet 725 * updated EAP-PSK to use draft 9 by default since this can now be 726 tested with hostapd; removed support for draft 3, including 727 server_nai configuration option from network blocks 728 * driver_wired: add PAE address to the multicast address list in order 729 to be able to receive EAPOL frames with drivers that do not include 730 these multicast addresses by default 731 * driver_wext: add support for WE-19 732 * added support for multiple configuration backends (CONFIG_BACKEND 733 option); currently, only 'file' is supported (i.e., the format used 734 in wpa_supplicant.conf) 735 * added support for updating configuration ('wpa_cli save_config'); 736 this is disabled by default and can be enabled with global 737 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli 738 and wpa_gui to store the configuration changes in a permanent store 739 * added GET_NETWORK ctrl_iface command 740 (e.g., 'wpa_cli get_network 0 ssid') 741 7422005-08-21 - v0.4.4 743 * replaced OpenSSL patch for EAP-FAST support 744 (openssl-tls-extensions.patch) with a more generic and correct 745 patch (the new patch is not compatible with the previous one, so the 746 OpenSSL library will need to be patched with the new patch in order 747 to be able to build wpa_supplicant with EAP-FAST support) 748 * added support for using Windows certificate store (through CryptoAPI) 749 for client certificate and private key operations (EAP-TLS) 750 (see wpa_supplicant.conf for more information on how to configure 751 this with private_key) 752 * ported wpa_gui to Windows 753 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be 754 built with the open source version of the Qt4 for Windows 755 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used 756 with drivers that do not support WPA 757 * ndis_events: fixed Windows 2000 support 758 * added support for enabling/disabling networks from the list of all 759 configured networks ('wpa_cli enable_network <network id>' and 760 'wpa_cli disable_network <network id>') 761 * added support for adding and removing network from the current 762 configuration ('wpa_cli add_network' and 'wpa_cli remove_network 763 <network id>'); added networks are disabled by default and they can 764 be enabled with enable_network command once the configuration is done 765 for the new network; note: configuration file is not yet updated, so 766 these new networks are lost when wpa_supplicant is restarted 767 * added support for setting network configuration parameters through 768 the control interface, for example: 769 wpa_cli set_network 0 ssid "\"my network\"" 770 * fixed parsing of strings that include both " and # within double 771 quoted area (e.g., "start"#end") 772 * added EAP workaround for PEAP session resumption: allow outer, 773 i.e., not tunneled, EAP-Success to terminate session since; this can 774 be disabled with eap_workaround=0 775 (this was allowed for PEAPv1 before, but now it is also allowed for 776 PEAPv0 since at least one RADIUS authentication server seems to be 777 doing this for PEAPv0, too) 778 * wpa_gui: added preliminary support for adding new networks to the 779 wpa_supplicant configuration (double click on the scan results to 780 open network configuration) 781 7822005-06-26 - v0.4.3 783 * removed interface for external EAPOL/EAP supplicant (e.g., 784 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required 785 anymore and is unlikely to be used by anyone 786 * driver_ndis: fixed WinPcap 3.0 support 787 * fixed build with CONFIG_DNET_PCAP=y on Linux 788 * l2_packet: moved different implementations into separate files 789 (l2_packet_*.c) 790 7912005-06-12 - v0.4.2 792 * driver_ipw: updated driver structures to match with ipw2200-1.0.4 793 (note: ipw2100-1.1.0 is likely to require an update to work with 794 this) 795 * added support for using ap_scan=2 mode with multiple network blocks; 796 wpa_supplicant will go through the networks one by one until the 797 driver reports a successful association; this uses the same order for 798 networks as scan_ssid=1 scans, i.e., the priority field is ignored 799 and the network block order in the file is used instead 800 * fixed a potential issue in RSN pre-authentication ending up using 801 freed memory if pre-authentication times out 802 * added support for matching alternative subject name extensions of the 803 authentication server certificate; new configuration variables 804 altsubject_match and altsubject_match2 805 * driver_ndis: added support for IEEE 802.1X authentication with wired 806 NDIS drivers 807 * added support for querying private key password (EAP-TLS) through the 808 control interface (wpa_cli/wpa_gui) if one is not included in the 809 configuration file 810 * driver_broadcom: fixed couple of memory leaks in scan result 811 processing 812 * EAP-PAX is now registered as EAP type 46 813 * fixed EAP-PAX MAC calculation 814 * fixed EAP-PAX CK and ICK key derivation 815 * added support for using password with EAP-PAX (as an alternative to 816 entering key with eappsk); SHA-1 hash of the password will be used as 817 the key in this case 818 * added support for arbitrary driver interface parameters through the 819 configuration file with a new driver_param field; this adds a new 820 driver_ops function set_param() 821 * added possibility to override l2_packet module with driver interface 822 API (new send_eapol handler); this can be used to implement driver 823 specific TX/RX functions for EAPOL frames 824 * fixed ctrl_interface_group processing for the case where gid is 825 entered as a number, not group name 826 * driver_test: added support for testing hostapd with wpa_supplicant 827 by using test driver interface without any kernel drivers or network 828 cards 829 8302005-05-22 - v0.4.1 831 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL 832 packets to be encrypted; this was apparently broken by the changed 833 ioctl order in v0.4.0 834 * driver_madwifi: added preliminary support for compiling against 'BSD' 835 branch of madwifi CVS tree 836 * added support for EAP-MSCHAPv2 password retries within the same EAP 837 authentication session 838 * added support for password changes with EAP-MSCHAPv2 (used when the 839 password has expired) 840 * added support for reading additional certificates from PKCS#12 files 841 and adding them to the certificate chain 842 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys 843 were used 844 * fixed a possible double free in EAP-TTLS fast-reauthentication when 845 identity or password is entered through control interface 846 * display EAP Notification messages to user through control interface 847 with "CTRL-EVENT-EAP-NOTIFICATION" prefix 848 * added GUI version of wpa_cli, wpa_gui; this is not build 849 automatically with 'make'; use 'make wpa_gui' to build (this requires 850 Qt development tools) 851 * added 'disconnect' command to control interface for setting 852 wpa_supplicant in state where it will not associate before 853 'reassociate' command has been used 854 * added support for selecting a network from the list of all configured 855 networks ('wpa_cli select_network <network id>'; this disabled all 856 other networks; to re-enable, 'wpa_cli select_network any') 857 * added support for getting scan results through control interface 858 * added EAP workaround for PEAPv1 session resumption: allow outer, 859 i.e., not tunneled, EAP-Success to terminate session since; this can 860 be disabled with eap_workaround=0 861 8622005-04-25 - v0.4.0 (beginning of 0.4.x development releases) 863 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be 864 used to reduce the size of the wpa_supplicant considerably if 865 debugging code is not needed 866 * fixed EAPOL-Key validation to drop packets with invalid Key Data 867 Length; such frames could have crashed wpa_supplicant due to buffer 868 overflow 869 * added support for wired authentication (IEEE 802.1X on wired 870 Ethernet); driver interface 'wired' 871 * obsoleted set_wpa() handler in the driver interface API (it can be 872 replaced by moving enable/disable functionality into init()/deinit()) 873 (calls to set_wpa() are still present for backwards compatibility, 874 but they may be removed in the future) 875 * driver_madwifi: fixed association in plaintext mode 876 * modified the EAP workaround that accepts EAP-Success with incorrect 877 Identifier to be even less strict about verification in order to 878 interoperate with some authentication servers 879 * added support for sending TLS alerts 880 * added support for 'any' SSID wildcard; if ssid is not configured or 881 is set to an empty string, any SSID will be accepted for non-WPA AP 882 * added support for asking PIN (for SIM) from frontends (e.g., 883 wpa_cli); if a PIN is needed, but not included in the configuration 884 file, a control interface request is sent and EAP processing is 885 delayed until the PIN is available 886 * added support for using external devices (e.g., a smartcard) for 887 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config); 888 new wpa_supplicant.conf variables: 889 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path 890 - network: engine, engine_id, key_id 891 * added experimental support for EAP-PAX 892 * added monitor mode for wpa_cli (-a<path to a program to run>) that 893 allows external commands (e.g., shell scripts) to be run based on 894 wpa_supplicant events, e.g., when authentication has been completed 895 and data connection is ready; other related wpa_cli arguments: 896 -B (run in background), -P (write PID file); wpa_supplicant has a new 897 command line argument (-W) that can be used to make it wait until a 898 control interface command is received in order to avoid missing 899 events 900 * added support for opportunistic WPA2 PMKSA key caching (disabled by 901 default, can be enabled with proactive_key_caching=1) 902 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where 903 Authenticator rejects PMKSA caching attempt and the driver is not 904 using assoc_info events 905 * added -P<pid file> argument for wpa_supplicant to write the current 906 process id into a file 907 9082005-02-12 - v0.3.7 (beginning of 0.3.x stable releases) 909 * added new phase1 option parameter, include_tls_length=1, to force 910 wpa_supplicant to add TLS Message Length field to all TLS messages 911 even if the packet is not fragmented; this may be needed with some 912 authentication servers 913 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when 914 using drivers that take care of AP selection (e.g., when using 915 ap_scan=2) 916 * fixed reprocessing of pending request after ctrl_iface requests for 917 identity/password/otp 918 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of 919 EAP-PEAP and EAP-TTLS 920 * all drivers using driver_wext: set interface up and select Managed 921 mode when starting wpa_supplicant; set interface down when exiting 922 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both 923 ipw2100 and ipw2200; please note that this also changed the 924 configuration variable in .config to CONFIG_DRIVER_IPW 925 9262005-01-24 - v0.3.6 927 * fixed a busy loop introduced in v0.3.5 for scan result processing 928 when no matching AP is found 929 9302005-01-23 - v0.3.5 931 * added a workaround for an interoperability issue with a Cisco AP 932 when using WPA2-PSK 933 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as 934 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow 935 retransmission of dropped frames) 936 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version 937 (e.g., segfault when processing EAPOL-Key frames) 938 * fixed EAP workaround and fast reauthentication configuration for 939 RSN pre-authentication; previously these were disabled and 940 pre-authentication would fail if the used authentication server 941 requires EAP workarounds 942 * added support for blacklisting APs that fail or timeout 943 authentication in ap_scan=1 mode so that all APs are tried in cases 944 where the ones with strongest signal level are failing authentication 945 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS 946 authentication attempt 947 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded 948 in the previous authentication (previously, only Phase 1 success was 949 verified) 950 9512005-01-09 - v0.3.4 952 * added preliminary support for IBSS (ad-hoc) mode configuration 953 (mode=1 in network block); this included a new key_mgmt mode 954 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no 955 key management; see wpa_supplicant.conf for more details and an 956 example on how to configure this (note: this is currently implemented 957 only for driver_hostapd.c, but the changes should be trivial to add 958 in associate() handler for other drivers, too (assuming the driver 959 supports WPA-None) 960 * added preliminary port for native Windows (i.e., no cygwin) using 961 mingw 962 9632005-01-02 - v0.3.3 964 * added optional support for GNU Readline and History Libraries for 965 wpa_cli (CONFIG_READLINE) 966 * cleaned up EAP state machine <-> method interface and number of 967 small problems with error case processing not terminating on 968 EAP-Failure but waiting for timeout 969 * added couple of workarounds for interoperability issues with a 970 Cisco AP when using WPA2 971 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt); 972 Note: This requires a patch for openssl to add support for TLS 973 extensions and number of workarounds for operations without 974 certificates. Proof of concept type of experimental patch is 975 included in openssl-tls-extensions.patch. 976 9772004-12-19 - v0.3.2 978 * fixed private key loading for cases where passphrase is not set 979 * fixed Windows/cygwin L2 packet handler freeing; previous version 980 could cause a segfault when RSN pre-authentication was completed 981 * added support for PMKSA caching with drivers that generate RSN IEs 982 (e.g., NDIS); currently, this is only implemented in driver_ndis.c, 983 but similar code can be easily added to driver_ndiswrapper.c once 984 ndiswrapper gets full support for RSN PMKSA caching 985 * improved recovery from PMKID mismatches by requesting full EAP 986 authentication in case of failed PMKSA caching attempt 987 * driver_ndis: added support for NDIS NdisMIncidateStatus() events 988 (this requires that ndis_events is ran while wpa_supplicant is 989 running) 990 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys 991 * added support for driver interfaces to replace the interface name 992 based on driver/OS specific mapping, e.g., in case of driver_ndis, 993 this allows the beginning of the adapter description to be used as 994 the interface name 995 * added support for CR+LF (Windows-style) line ends in configuration 996 file 997 * driver_ndis: enable radio before starting scanning, disable radio 998 when exiting 999 * modified association event handler to set portEnabled = FALSE before 1000 clearing port Valid in order to reset EAP state machine and avoid 1001 problems with new authentication getting ignored because of state 1002 machines ending up in AUTHENTICATED/SUCCESS state based on old 1003 information 1004 * added support for driver events to add PMKID candidates in order to 1005 allow drivers to give priority to most likely roaming candidates 1006 * driver_hostap: moved PrivacyInvoked configuration to associate() 1007 function so that this will not be set for plaintext connections 1008 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver 1009 interface can distinguish plaintext and IEEE 802.1X (no WPA) 1010 authentication 1011 * fixed static WEP key configuration to use broadcast/default type for 1012 all keys (previously, the default TX key was configured as pairwise/ 1013 unicast key) 1014 * driver_ndis: added legacy WPA capability detection for non-WPA2 1015 drivers 1016 * added support for setting static WEP keys for IEEE 802.1X without 1017 dynamic WEP keying (eapol_flags=0) 1018 10192004-12-12 - v0.3.1 1020 * added support for reading PKCS#12 (PFX) files (as a replacement for 1021 PEM/DER) to get certificate and private key (CONFIG_PKCS12) 1022 * fixed compilation with CONFIG_PCSC=y 1023 * added new ap_scan mode, ap_scan=2, for drivers that take care of 1024 association, but need to be configured with security policy and SSID, 1025 e.g., ndiswrapper and NDIS driver; this mode should allow such 1026 drivers to work with hidden SSIDs and optimized roaming; when 1027 ap_scan=2 is used, only the first network block in the configuration 1028 file is used and this configuration should have explicit security 1029 policy (i.e., only one option in the lists) for key_mgmt, pairwise, 1030 group, proto variables 1031 * added experimental port of wpa_supplicant for Windows 1032 - driver_ndis.c driver interface (NDIS OIDs) 1033 - currently, this requires cygwin and WinPcap 1034 - small utility, win_if_list, can be used to get interface name 1035 * control interface can now be removed at build time; add 1036 CONFIG_CTRL_IFACE=y to .config to maintain old functionality 1037 * optional Xsupplicant interface can now be removed at build time; 1038 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back) 1039 * added auth_alg to driver interface associate() parameters to make it 1040 easier for drivers to configure authentication algorithm as part of 1041 the association 1042 10432004-12-05 - v0.3.0 (beginning of 0.3.x development releases) 1044 * driver_broadcom: added new driver interface for Broadcom wl.o driver 1045 (a generic driver for Broadcom IEEE 802.11a/g cards) 1046 * wpa_cli: fixed parsing of -p <path> command line argument 1047 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS 1048 ACK, not tunneled EAP-Success (of which only the first byte was 1049 actually send due to a bug in previous code); this seems to 1050 interoperate with most RADIUS servers that implements PEAPv1 1051 * PEAPv1: added support for terminating PEAP authentication on tunneled 1052 EAP-Success message; this can be configured by adding 1053 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf 1054 (some RADIUS servers require this whereas others require a tunneled 1055 reply 1056 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to 1057 the old label for key derivation; previously, the default was 1, 1058 but it looks like most existing PEAPv1 implementations use the old 1059 label which is thus more suitable default option 1060 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt) 1061 * fixed parsing of wep_tx_keyidx 1062 * added support for configuring list of allowed Phase 2 EAP types 1063 (for both EAP-PEAP and EAP-TTLS) instead of only one type 1064 * added support for configuring IEEE 802.11 authentication algorithm 1065 (auth_alg; mainly for using Shared Key authentication with static 1066 WEP keys) 1067 * added support for EAP-AKA (with UMTS SIM) 1068 * fixed couple of errors in PCSC handling that could have caused 1069 random-looking errors for EAP-SIM 1070 * added support for EAP-SIM pseudonyms and fast re-authentication 1071 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS 1072 session resumption) 1073 * added support for EAP-SIM with two challanges 1074 (phase1="sim_min_num_chal=3" can be used to require three challenges) 1075 * added support for configuring DH/DSA parameters for an ephemeral DH 1076 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters 1077 dh_file and dh_file2 (phase 2); this adds support for using DSA keys 1078 and optional DH key exchange to achieve forward secracy with RSA keys 1079 * added support for matching subject of the authentication server 1080 certificate with a substring when using EAP-TLS/PEAP/TTLS; new 1081 configuration variables subject_match and subject_match2 1082 * changed SSID configuration in driver_wext.c (used by many driver 1083 interfaces) to use ssid_len+1 as the length for SSID since some Linux 1084 drivers expect this 1085 * fixed couple of unaligned reads in scan result parsing to fix WPA 1086 connection on some platforms (e.g., ARM) 1087 * added driver interface for Intel ipw2100 driver 1088 * added support for LEAP with WPA 1089 * added support for larger scan results report (old limit was 4 kB of 1090 data, i.e., about 35 or so APs) when using Linux wireless extensions 1091 v17 or newer 1092 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start 1093 only if there is a PMKSA cache entry for the current AP 1094 * fixed error handling for case where reading of scan results fails: 1095 must schedule a new scan or wpa_supplicant will remain waiting 1096 forever 1097 * changed debug output to remove shared password/key material by 1098 default; all key information can be included with -K command line 1099 argument to match the previous behavior 1100 * added support for timestamping debug log messages (disabled by 1101 default, can be enabled with -t command line argument) 1102 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104 1103 if keys are not configured to be used; this fixes IEEE 802.1X mode 1104 with drivers that use this information to configure whether Privacy 1105 bit can be in Beacon frames (e.g., ndiswrapper) 1106 * avoid clearing driver keys if no keys have been configured since last 1107 key clear request; this seems to improve reliability of group key 1108 handshake for ndiswrapper & NDIS driver which seems to be suffering 1109 of some kind of timing issue when the keys are cleared again after 1110 association 1111 * changed driver interface API: 1112 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which 1113 version is being used (now, this is set to 2; previously, it was 1114 not defined) 1115 - pass pointer to private data structure to all calls 1116 - the new API is not backwards compatible; all in-tree driver 1117 interfaces has been converted to the new API 1118 * added support for controlling multiple interfaces (radios) per 1119 wpa_supplicant process; each interface needs to be listed on the 1120 command line (-c, -i, -D arguments) with -N as a separator 1121 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi) 1122 * added a workaround for EAP servers that incorrectly use same Id for 1123 sequential EAP packets 1124 * changed libpcap/libdnet configuration to use .config variable, 1125 CONFIG_DNET_PCAP, instead of requiring Makefile modification 1126 * improved downgrade attack detection in IE verification of msg 3/4: 1127 verify both WPA and RSN IEs, if present, not only the selected one; 1128 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or 1129 Probe Response frame, and RSN is enabled in wpa_supplicant 1130 configuration 1131 * fixed WPA msg 3/4 processing to allow Key Data field contain other 1132 IEs than just one WPA IE 1133 * added support for FreeBSD and driver interface for the BSD net80211 1134 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the 1135 required kernel mods have not yet been committed 1136 * made EAP workarounds configurable; enabled by default, can be 1137 disabled with network block option eap_workaround=0 1138 11392004-07-17 - v0.2.4 (beginning of 0.2.x stable releases) 1140 * resolved couple of interoperability issues with EAP-PEAPv1 and 1141 Phase 2 (inner EAP) fragment reassembly 1142 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the 1143 AP is using non-zero key index for the unicast key and key index zero 1144 for the broadcast key 1145 * driver_hostap: fixed IEEE 802.1X WEP key updates and 1146 re-authentication by allowing unencrypted EAPOL frames when not using 1147 WPA 1148 * added a new driver interface, 'wext', which uses only standard, 1149 driver independent functionality in Linux wireless extensions; 1150 currently, this can be used only for non-WPA IEEE 802.1X mode, but 1151 eventually, this is to be extended to support full WPA/WPA2 once 1152 Linux wireless extensions get support for this 1153 * added support for mode in which the driver is responsible for AP 1154 scanning and selection; this is disabled by default and can be 1155 enabled with global ap_scan=0 variable in wpa_supplicant.conf; 1156 this mode can be used, e.g., with generic 'wext' driver interface to 1157 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver 1158 supporting wireless extensions. 1159 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g., 1160 operation with an AP that does not include SSID in the Beacon frames) 1161 * added support for new EAP authentication methods: 1162 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP 1163 * added support for asking one-time-passwords from frontends (e.g., 1164 wpa_cli); this 'otp' command works otherwise like 'password' command, 1165 but the password is used only once and the frontend will be asked for 1166 a new password whenever a request from authenticator requires a 1167 password; this can be used with both EAP-OTP and EAP-GTC 1168 * changed wpa_cli to automatically re-establish connection so that it 1169 does not need to be re-started when wpa_supplicant is terminated and 1170 started again 1171 * improved user data (identity/password/otp) requests through 1172 frontends: process pending EAPOL packets after getting new 1173 information so that full authentication does not need to be 1174 restarted; in addition, send pending requests again whenever a new 1175 frontend is attached 1176 * changed control frontends to use a new directory for socket files to 1177 make it easier for wpa_cli to automatically select between interfaces 1178 and to provide access control for the control interface; 1179 wpa_supplicant.conf: ctrl_interface is now a path 1180 (/var/run/wpa_supplicant is the recommended path) and 1181 ctrl_interface_group can be used to select which group gets access to 1182 the control interface; 1183 wpa_cli: by default, try to connect to the first interface available 1184 in /var/run/wpa_supplicant; this path can be overriden with -p option 1185 and an interface can be selected with -i option (i.e., in most common 1186 cases, wpa_cli does not need to get any arguments) 1187 * added support for LEAP 1188 * added driver interface for Linux ndiswrapper 1189 * added priority option for network blocks in the configuration file; 1190 this allows networks to be grouped based on priority (the scan 1191 results are searched for matches with network blocks in this order) 1192 11932004-06-20 - v0.2.3 1194 * sort scan results to improve AP selection 1195 * fixed control interface socket removal for some error cases 1196 * improved scan requesting and authentication timeout 1197 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and 1198 TLS processing 1199 * PEAP version can now be forced with phase1="peapver=<ver>" 1200 (mostly for testing; by default, the highest version supported by 1201 both the Supplicant and Authentication Server is selected 1202 automatically) 1203 * added support for madwifi driver (Atheros ar521x) 1204 * added a workaround for cases where AP sets Install Tx/Rx bit for 1205 WPA Group Key messages when pairwise keys are used (without this, 1206 the Group Key would be used for Tx and the AP would drop frames 1207 from the station) 1208 * added GSM SIM/USIM interface for GSM authentication algorithm for 1209 EAP-SIM; this requires pcsc-lite 1210 * added support for ATMEL AT76C5XXx driver 1211 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator 1212 does not include key data in the EAPOL-Key frame (i.e., part of 1213 EAP keying material is used as data encryption key) 1214 * added support for using plaintext and static WEP networks 1215 (key_mgmt=NONE) 1216 12172004-05-31 - v0.2.2 1218 * added support for new EAP authentication methods: 1219 EAP-TTLS/EAP-MD5-Challenge 1220 EAP-TTLS/EAP-GTC 1221 EAP-TTLS/EAP-MSCHAPv2 1222 EAP-TTLS/EAP-TLS 1223 EAP-TTLS/MSCHAPv2 1224 EAP-TTLS/MSCHAP 1225 EAP-TTLS/PAP 1226 EAP-TTLS/CHAP 1227 EAP-PEAP/TLS 1228 EAP-PEAP/GTC 1229 EAP-PEAP/MD5-Challenge 1230 EAP-GTC 1231 EAP-SIM (not yet complete; needs GSM/SIM authentication interface) 1232 * added support for anonymous identity (to be used when identity is 1233 sent in plaintext; real identity will be used within TLS protected 1234 tunnel (e.g., with EAP-TTLS) 1235 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli 1236 * added support for requesting identity and password information using 1237 control interface; in other words, the password for EAP-PEAP or 1238 EAP-TTLS does not need to be included in the configuration file since 1239 a frontand (e.g., wpa_cli) can ask it from the user 1240 * improved RSN pre-authentication to use a candidate list and process 1241 all candidates from each scan; not only one per scan 1242 * fixed RSN IE and WPA IE capabilities field parsing 1243 * ignore Tx bit in GTK IE when Pairwise keys are used 1244 * avoid making new scan requests during IEEE 802.1X negotiation 1245 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant 1246 with TLS support (this replaces the included implementation with 1247 library code to save about 8 kB since the library code is needed 1248 anyway for TLS) 1249 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support 1250 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config) 1251 12522004-05-06 - v0.2.1 1253 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1) 1254 Supplicant 1255 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1] 1256 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf] 1257 - EAP-MD5 (cannot be used with WPA-RADIUS) 1258 [draft-ietf-eap-rfc2284bis-09.txt] 1259 - EAP-TLS [RFC 2716] 1260 - EAP-MSCHAPv2 (currently used only with EAP-PEAP) 1261 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt] 1262 [draft-kamath-pppext-eap-mschapv2-00.txt] 1263 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by 1264 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey) 1265 - new configuration file options: eap, identity, password, ca_cert, 1266 client_cert, privatekey, private_key_passwd 1267 - Xsupplicant is not required anymore, but it can be used by 1268 disabling the internal IEEE 802.1X Supplicant with -e command line 1269 option 1270 - this code is not included in the default build; Makefile need to 1271 be edited for this (uncomment lines for selected functionality) 1272 - EAP-TLS and EAP-PEAP require openssl libraries 1273 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..) 1274 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys 1275 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X 1276 EAPOL-Key frames instead of WPA key handshakes) 1277 * added support for IEEE 802.11i/RSN (WPA2) 1278 - improved PTK Key Handshake 1279 - PMKSA caching, pre-authentication 1280 * fixed wpa_supplicant to ignore possible extra data after WPA 1281 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using 1282 TPTK' error from message 3 of 4-Way Handshake in case the AP 1283 includes extra data after the EAPOL-Key) 1284 * added interface for external programs (frontends) to control 1285 wpa_supplicant 1286 - CLI example (wpa_cli) with interactive mode and command line 1287 mode 1288 - replaced SIGUSR1 status/statistics with the new control interface 1289 * made some feature compile time configurable 1290 - .config file for make 1291 - driver interfaces (hostap, hermes, ..) 1292 - EAPOL/EAP functions 1293 12942004-02-15 - v0.2.0 1295 * Initial version of wpa_supplicant 1296
