1ChangeLog for wpa_supplicant 2 32010-09-07 - v0.7.3 4 * fixed fallback from failed PMKSA caching into full EAP authentication 5 [Bug 355] 6 * fixed issue with early D-Bus signals during initialization 7 * fixed X.509 name handling in internal TLS 8 * fixed WPS ER to use corrent Enrollee MAC Address in Credential 9 * fixed scanning routines ot improve AP selection for WPS 10 * added WPS workaround for open networks 11 * fixed WPS Diffie-Hellman derivation to use correct public key length 12 * fixed wpa_supplicant AP mode operations to ignore Supplicant and 13 scan result events 14 * improved SME operations with nl80211 15 * fixed WPS ER event_id handling in some cases 16 * fixed some issues with bgscan simple to avoid unnecessary scans 17 * fixed issue with l2_packet_ndis overlapped writes corrupting stack 18 [Bug 328] 19 * updated WinPcap to the latest stable version 4.1.2 in Windows 20 installer 21 222010-04-18 - v0.7.2 23 * nl80211: fixed number of issues with roaming 24 * avoid unnecessary roaming if multiple APs with similar signal 25 strength are present in scan results 26 * add TLS client events and server probing to ease design of 27 automatic detection of EAP parameters 28 * add option for server certificate matching (SHA256 hash of the 29 certificate) instead of trusted CA certificate configuration 30 * bsd: Cleaned up driver wrapper and added various low-level 31 configuration options 32 * wpa_gui-qt4: do not show too frequent WPS AP available events as 33 tray messages 34 * TNC: fixed issues with fragmentation 35 * EAP-TNC: add Flags field into fragment acknowledgement (needed to 36 interoperate with other implementations; may potentially breaks 37 compatibility with older wpa_supplicant/hostapd versions) 38 * wpa_cli: added option for using a separate process to receive event 39 messages to reduce latency in showing these 40 (CFLAGS += -DCONFIG_WPA_CLI_FORK=y in .config to enable this) 41 * maximum BSS table size can now be configured (bss_max_count) 42 * BSSes to be included in the BSS table can be filtered based on 43 configured SSIDs to save memory (filter_ssids) 44 * fix number of issues with IEEE 802.11r/FT; this version is not 45 backwards compatible with old versions 46 * nl80211: add support for IEEE 802.11r/FT protocol (both over-the-air 47 and over-the-DS) 48 * add freq_list network configuration parameter to allow the AP 49 selection to filter out entries based on the operating channel 50 * add signal strength change events for bgscan; this allows more 51 dynamic changes to background scanning interval based on changes in 52 the signal strength with the current AP; this improves roaming within 53 ESS quite a bit, e.g., with bgscan="simple:30:-45:300" in the network 54 configuration block to request background scans less frequently when 55 signal strength remains good and to automatically trigger background 56 scans whenever signal strength drops noticeably 57 (this is currently only available with nl80211) 58 * add BSSID and reason code (if available) to disconnect event messages 59 * wpa_gui-qt4: more complete support for translating the GUI with 60 linguist and add German translation 61 * fix DH padding with internal crypto code (mainly, for WPS) 62 * do not trigger initial scan automatically anymore if there are no 63 enabled networks 64 652010-01-16 - v0.7.1 66 * cleaned up driver wrapper API (struct wpa_driver_ops); the new API 67 is not fully backwards compatible, so out-of-tree driver wrappers 68 will need modifications 69 * cleaned up various module interfaces 70 * merge hostapd and wpa_supplicant developers' documentation into a 71 single document 72 * nl80211: use explicit deauthentication to clear cfg80211 state to 73 avoid issues when roaming between APs 74 * dbus: major design changes in the new D-Bus API 75 (fi.w1.wpa_supplicant1) 76 * nl80211: added support for IBSS networks 77 * added internal debugging mechanism with backtrace support and memory 78 allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y) 79 * added WPS ER unsubscription command to more cleanly unregister from 80 receiving UPnP events when ER is terminated 81 * cleaned up AP mode operations to avoid need for virtual driver_ops 82 wrapper 83 * added BSS table to maintain more complete scan result information 84 over multiple scans (that may include only partial results) 85 * wpa_gui-qt4: update Peers dialog information more dynamically while 86 the dialog is kept open 87 * fixed PKCS#12 use with OpenSSL 1.0.0 88 * driver_wext: Added cfg80211-specific optimization to avoid some 89 unnecessary scans and to speed up association 90 912009-11-21 - v0.7.0 92 * increased wpa_cli ping interval to 5 seconds and made this 93 configurable with a new command line options (-G<seconds>) 94 * fixed scan buffer processing with WEXT to handle up to 65535 95 byte result buffer (previously, limited to 32768 bytes) 96 * allow multiple driver wrappers to be specified on command line 97 (e.g., -Dnl80211,wext); the first one that is able to initialize the 98 interface will be used 99 * added support for multiple SSIDs per scan request to optimize 100 scan_ssid=1 operations in ap_scan=1 mode (i.e., search for hidden 101 SSIDs); this requires driver support and can currently be used only 102 with nl80211 103 * added support for WPS USBA out-of-band mechanism with USB Flash 104 Drives (UFD) (CONFIG_WPS_UFD=y) 105 * driver_ndis: add PAE group address to the multicast address list to 106 fix wired IEEE 802.1X authentication 107 * fixed IEEE 802.11r key derivation function to match with the standard 108 (note: this breaks interoperability with previous version) [Bug 303] 109 * added better support for drivers that allow separate authentication 110 and association commands (e.g., mac80211-based Linux drivers with 111 nl80211; SME in wpa_supplicant); this allows over-the-air FT protocol 112 to be used (IEEE 802.11r) 113 * fixed SHA-256 based key derivation function to match with the 114 standard when using CCMP (for IEEE 802.11r and IEEE 802.11w) 115 (note: this breaks interoperability with previous version) [Bug 307] 116 * use shared driver wrapper files with hostapd 117 * added AP mode functionality (CONFIG_AP=y) with mode=2 in the network 118 block; this can be used for open and WPA2-Personal networks 119 (optionally, with WPS); this links in parts of hostapd functionality 120 into wpa_supplicant 121 * wpa_gui-qt4: added new Peers dialog to show information about peers 122 (other devices, including APs and stations, etc. in the neighborhood) 123 * added support for WPS External Registrar functionality (configure APs 124 and enroll new devices); can be used with wpa_gui-qt4 Peers dialog 125 and wpa_cli commands wps_er_start, wps_er_stop, wps_er_pin, 126 wps_er_pbc, wps_er_learn 127 (this can also be used with a new 'none' driver wrapper if no 128 wireless device or IEEE 802.1X on wired is needed) 129 * driver_nl80211: multiple updates to provide support for new Linux 130 nl80211/mac80211 functionality 131 * updated management frame protection to use IEEE Std 802.11w-2009 132 * fixed number of small WPS issues and added workarounds to 133 interoperate with common deployed broken implementations 134 * added support for NFC out-of-band mechanism with WPS 135 * driver_ndis: fixed wired IEEE 802.1X authentication with PAE group 136 address frames 137 * added preliminary support for IEEE 802.11r RIC processing 138 * added support for specifying subset of enabled frequencies to scan 139 (scan_freq option in the network configuration block); this can speed 140 up scanning process considerably if it is known that only a small 141 subset of channels is actually used in the network (this is currently 142 supported only with -Dnl80211) 143 * added a workaround for race condition between receiving the 144 association event and the following EAPOL-Key 145 * added background scan and roaming infrastructure to allow 146 network-specific optimizations to be used to improve roaming within 147 an ESS (same SSID) 148 * added new DBus interface (fi.w1.wpa_supplicant1) 149 1502009-01-06 - v0.6.7 151 * added support for Wi-Fi Protected Setup (WPS) 152 (wpa_supplicant can now be configured to act as a WPS Enrollee to 153 enroll credentials for a network using PIN and PBC methods; in 154 addition, wpa_supplicant can act as a wireless WPS Registrar to 155 configure an AP); WPS support can be enabled by adding CONFIG_WPS=y 156 into .config and setting the runtime configuration variables in 157 wpa_supplicant.conf (see WPS section in the example configuration 158 file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to 159 manage WPS negotiation; see README-WPS for more details 160 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf) 161 * added support for using driver_test over UDP socket 162 * fixed PEAPv0 Cryptobinding interoperability issue with Windows Server 163 2008 NPS; optional cryptobinding is now enabled (again) by default 164 * fixed PSK editing in wpa_gui 165 * changed EAP-GPSK to use the IANA assigned EAP method type 51 166 * added a Windows installer that includes WinPcap and all the needed 167 DLLs; in addition, it set up the registry automatically so that user 168 will only need start wpa_gui to get prompted to start the wpasvc 169 servide and add a new interface if needed through wpa_gui dialog 170 * updated management frame protection to use IEEE 802.11w/D7.0 171 1722008-11-23 - v0.6.6 173 * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA 174 (can be used to simulate test SIM/USIM card with a known private key; 175 enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config 176 and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration) 177 * added a new network configuration option, wpa_ptk_rekey, that can be 178 used to enforce frequent PTK rekeying, e.g., to mitigate some attacks 179 against TKIP deficiencies 180 * added an optional mitigation mechanism for certain attacks against 181 TKIP by delaying Michael MIC error reports by a random amount of time 182 between 0 and 60 seconds; this can be enabled with a build option 183 CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config 184 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits, 185 not bytes 186 * updated OpenSSL code for EAP-FAST to use an updated version of the 187 session ticket overriding API that was included into the upstream 188 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is 189 needed with that version anymore) 190 * updated userspace MLME instructions to match with the current Linux 191 mac80211 implementation; please also note that this can only be used 192 with driver_nl80211.c (the old code from driver_wext.c was removed) 193 * added support (Linux only) for RoboSwitch chipsets (often found in 194 consumer grade routers); driver interface 'roboswitch' 195 * fixed canceling of PMKSA caching when using drivers that generate 196 RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know 197 about 198 1992008-11-01 - v0.6.5 200 * added support for SHA-256 as X.509 certificate digest when using the 201 internal X.509/TLSv1 implementation 202 * updated management frame protection to use IEEE 802.11w/D6.0 203 * added support for using SHA256-based stronger key derivation for WPA2 204 (IEEE 802.11w) 205 * fixed FT (IEEE 802.11r) authentication after a failed association to 206 use correct FTIE 207 * added support for configuring Phase 2 (inner/tunneled) authentication 208 method with wpa_gui-qt4 209 2102008-08-10 - v0.6.4 211 * added support for EAP Sequences in EAP-FAST Phase 2 212 * added support for using TNC with EAP-FAST 213 * added driver_ps3 for the PS3 Linux wireless driver 214 * added support for optional cryptobinding with PEAPv0 215 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to 216 allow fallback to full handshake if server rejects PAC-Opaque 217 * added fragmentation support for EAP-TNC 218 * added support for parsing PKCS #8 formatted private keys into the 219 internal TLS implementation (both PKCS #1 RSA key and PKCS #8 220 encapsulated RSA key can now be used) 221 * added option of using faster, but larger, routines in the internal 222 LibTomMath (for internal TLS implementation) to speed up DH and RSA 223 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y) 224 * fixed race condition between disassociation event and group key 225 handshake to avoid getting stuck in incorrect state [Bug 261] 226 * fixed opportunistic key caching (proactive_key_caching) 227 2282008-02-22 - v0.6.3 229 * removed 'nai' and 'eappsk' network configuration variables that were 230 previously used for configuring user identity and key for EAP-PSK, 231 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the 232 replacement for 'nai' (if old configuration used a separate 233 'identity' value, that would now be configured as 234 'anonymous_identity'). 'password' field is now used as the 235 replacement for 'eappsk' (it can also be set using hexstring to 236 present random binary data) 237 * removed '-w' command line parameter (wait for interface to be added, 238 if needed); cleaner way of handling this functionality is to use an 239 external mechanism (e.g., hotplug scripts) that start wpa_supplicant 240 when an interface is added 241 * updated FT support to use the latest draft, IEEE 802.11r/D9.0 242 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for 243 indicating when new scan results become available 244 * added new ctrl_iface command, BSS, to allow scan results to be 245 fetched without hitting the message size limits (this command 246 can be used to iterate through the scan results one BSS at the time) 247 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION 248 attributes in EAP-SIM Start/Response when using fast reauthentication 249 * fixed EAPOL not to end up in infinite loop when processing dynamic 250 WEP keys with IEEE 802.1X 251 * fixed problems in getting NDIS events from WMI on Windows 2000 252 2532008-01-01 - v0.6.2 254 * added support for Makefile builds to include debug-log-to-a-file 255 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line) 256 * fixed EAP-SIM and EAP-AKA message parser to validate attribute 257 lengths properly to avoid potential crash caused by invalid messages 258 * added data structure for storing allocated buffers (struct wpabuf); 259 this does not affect wpa_supplicant usage, but many of the APIs 260 changed and various interfaces (e.g., EAP) is not compatible with old 261 versions 262 * added support for protecting EAP-AKA/Identity messages with 263 AT_CHECKCODE (optional feature in RFC 4187) 264 * added support for protected result indication with AT_RESULT_IND for 265 EAP-SIM and EAP-AKA (phase1="result_ind=1") 266 * added driver_wext workaround for race condition between scanning and 267 association with drivers that take very long time to scan all 268 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now 269 using a longer hardcoded timeout for the scan if the driver supports 270 notifications for scan completion (SIOCGIWSCAN event); this helps, 271 e.g., in cases where wpa_supplicant and madwifi driver ended up in 272 loop where the driver did not even try to associate 273 * stop EAPOL timer tick when no timers are in use in order to reduce 274 power consumption (no need to wake up the process once per second) 275 [Bug 237] 276 * added support for privilege separation (run only minimal part of 277 wpa_supplicant functionality as root and rest as unprivileged, 278 non-root process); see 'Privilege separation' in README for details; 279 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y 280 in .config 281 * changed scan results data structure to include all information 282 elements to make it easier to support new IEs; old get_scan_result() 283 driver_ops is still supported for backwards compatibility (results 284 are converted internally to the new format), but all drivers should 285 start using the new get_scan_results2() to make them more likely to 286 work with new features 287 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4 288 application, i.e., it does not require Qt3Support anymore; Windows 289 binary of wpa_gui.exe is now from this directory and only requires 290 QtCore4.dll and QtGui4.dll libraries 291 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs 292 available as a separate package to make wpa_gui installation easier: 293 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip 294 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt); 295 only shared key/password authentication is supported in this version 296 2972007-11-24 - v0.6.1 298 * added support for configuring password as NtPasswordHash 299 (16-byte MD4 hash of password) in hash:<32 hex digits> format 300 * added support for fallback from abbreviated TLS handshake to 301 full handshake when using EAP-FAST (e.g., due to an expired 302 PAC-Opaque) 303 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 304 draft (draft-ietf-emu-eap-gpsk-07.txt) 305 * added support for drivers that take care of RSN 4-way handshake 306 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and 307 WPA_ALG_PMK in set_key) 308 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in 309 .config); this version supports only ap_scan=2 mode and allow the 310 driver to take care of the 4-way handshake 311 * fixed a buffer overflow in parsing TSF from scan results when using 312 driver_wext.c with a driver that includes the TSF (e.g., iwl4965) 313 [Bug 232] 314 * updated FT support to use the latest draft, IEEE 802.11r/D8.0 315 * fixed an integer overflow issue in the ASN.1 parser used by the 316 (experimental) internal TLS implementation to avoid a potential 317 buffer read overflow 318 * fixed a race condition with -W option (wait for a control interface 319 monitor before starting) that could have caused the first messages to 320 be lost 321 * added support for processing TNCC-TNCS-Messages to report 322 recommendation (allow/none/isolate) when using TNC [Bug 243] 323 3242007-05-28 - v0.6.0 325 * added network configuration parameter 'frequency' for setting 326 initial channel for IBSS (adhoc) networks 327 * added experimental IEEE 802.11r/D6.0 support 328 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48 329 * updated EAP-PSK to use the IANA-allocated EAP type 47 330 * fixed EAP-PAX key derivation 331 * fixed EAP-PSK bit ordering of the Flags field 332 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in 333 tunnelled identity request (previously, the identifier from the outer 334 method was used, not the tunnelled identifier which could be 335 different) 336 * added support for fragmentation of outer TLS packets during Phase 2 337 of EAP-PEAP/TTLS/FAST 338 * fixed EAP-TTLS AVP parser processing for too short AVP lengths 339 * added support for EAP-FAST authentication with inner methods that 340 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported 341 for PAC provisioning) 342 * added support for authenticated EAP-FAST provisioning 343 * added support for configuring maximum number of EAP-FAST PACs to 344 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string) 345 * added support for storing EAP-FAST PACs in binary format 346 (fast_pac_format=binary in phase1 string) 347 * fixed dbus ctrl_iface to validate message interface before 348 dispatching to avoid a possible segfault [Bug 190] 349 * fixed PeerKey key derivation to use the correct PRF label 350 * updated Windows binary build to link against OpenSSL 0.9.8d and 351 added support for EAP-FAST 352 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 353 draft (draft-ietf-emu-eap-gpsk-04.txt) 354 * fixed EAP-AKA Notification processing to allow Notification to be 355 processed after AKA Challenge response has been sent 356 * updated to use IEEE 802.11w/D2.0 for management frame protection 357 (still experimental) 358 * fixed EAP-TTLS implementation not to crash on use of freed memory 359 if TLS library initialization fails 360 * added support for EAP-TNC (Trusted Network Connect) 361 (this version implements the EAP-TNC method and EAP-TTLS changes 362 needed to run two methods in sequence (IF-T) and the IF-IMC and 363 IF-TNCCS interfaces from TNCC) 364 3652006-11-24 - v0.5.6 366 * added experimental, integrated TLSv1 client implementation with the 367 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by 368 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in 369 .config); this can be useful, e.g., if the target system does not 370 have a suitable TLS library and a minimal code size is required 371 (total size of this internal TLS/crypto code is bit under 50 kB on 372 x86 and the crypto code is shared by rest of the supplicant so some 373 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB) 374 * removed STAKey handshake since PeerKey handshake has replaced it in 375 IEEE 802.11ma and there are no known deployments of STAKey 376 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 377 draft (draft-ietf-emu-eap-gpsk-01.txt) 378 * added preliminary implementation of IEEE 802.11w/D1.0 (management 379 frame protection) 380 (Note: this requires driver support to work properly.) 381 (Note2: IEEE 802.11w is an unapproved draft and subject to change.) 382 * fixed Windows named pipes ctrl_iface to not stop listening for 383 commands if client program opens a named pipe and closes it 384 immediately without sending a command 385 * fixed USIM PIN status determination for the case that PIN is not 386 needed (this allows EAP-AKA to be used with USIM cards that do not 387 use PIN) 388 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to 389 be used with cards that do not support file selection based on 390 partial AID 391 * added support for matching the subjectAltName of the authentication 392 server certificate against multiple name components (e.g., 393 altsubject_match="DNS:server.example.com;DNS:server2.example.com") 394 * fixed EAP-SIM/AKA key derivation for re-authentication case (only 395 affects IEEE 802.1X with dynamic WEP keys) 396 * changed ctrl_iface network configuration 'get' operations to not 397 return password/key material; if these fields are requested, "*" 398 will be returned if the password/key is set, but the value of the 399 parameter is not exposed 400 4012006-08-27 - v0.5.5 402 * added support for building Windows version with UNICODE defined 403 (wide-char functions) 404 * driver_ndis: fixed static WEP configuration to avoid race condition 405 issues with some NDIS drivers between association and setting WEP 406 keys 407 * driver_ndis: added validation for IELength value in scan results to 408 avoid crashes when using buggy NDIS drivers [Bug 165] 409 * fixed Release|Win32 target in the Visual Studio project files 410 (previously, only Debug|Win32 target was set properly) 411 * changed control interface API call wpa_ctrl_pending() to allow it to 412 return -1 on error (e.g., connection lost); control interface clients 413 will need to make sure that they verify that the value is indeed >0 414 when determining whether there are pending messages 415 * added an alternative control interface backend for Windows targets: 416 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default 417 control interface mechanism for Windows builds (previously, UDP to 418 localhost was used) 419 * changed ctrl_interface configuration for UNIX domain sockets: 420 - deprecated ctrl_interface_group variable (it may be removed in 421 future versions) 422 - allow both directory and group be configured with ctrl_interface 423 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel 424 - ctrl_interface=/var/run/wpa_supplicant is still supported for the 425 case when group is not changed 426 * added support for controlling more than one interface per process in 427 Windows version 428 * added a workaround for a case where the AP is using unknown address 429 (e.g., MAC address of the wired interface) as the source address for 430 EAPOL-Key frames; previously, that source address was used as the 431 destination for EAPOL-Key frames and in key derivation; now, BSSID is 432 used even if the source address does not match with it 433 (this resolves an interoperability issue with Thomson SpeedTouch 580) 434 * added a workaround for UDP-based control interface (which was used in 435 Windows builds before this release) to prevent packets with forged 436 addresses from being accepted as local control requests 437 * removed ndis_events.cpp and possibility of using external 438 ndis_events.exe; C version (ndis_events.c) is fully functional and 439 there is no desire to maintain two separate versions of this 440 implementation 441 * ndis_events: Changed NDIS event notification design to use WMI to 442 learn the adapter description through Win32_PnPEntity class; this 443 should fix some cases where the adapter name was not recognized 444 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500 445 USB) [Bug 113] 446 * fixed selection of the first network in ap_scan=2 mode; previously, 447 wpa_supplicant could get stuck in SCANNING state when only the first 448 network for enabled (e.g., after 'wpa_cli select_network 0') 449 * winsvc: added support for configuring ctrl_interface parameters in 450 registry (ctrl_interface string value in 451 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is 452 required to enable control interface (previously, this was hardcoded 453 to be enabled) 454 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4 455 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format 456 4572006-06-20 - v0.5.4 458 * fixed build with CONFIG_STAKEY=y [Bug 143] 459 * added support for doing MLME (IEEE 802.11 management frame 460 processing) in wpa_supplicant when using Devicescape IEEE 802.11 461 stack (wireless-dev.git tree) 462 * added a new network block configuration option, fragment_size, to 463 configure the maximum EAP fragment size 464 * driver_ndis: Disable WZC automatically for the selected interface to 465 avoid conflicts with two programs trying to control the radio; WZC 466 will be re-enabled (if it was enabled originally) when wpa_supplicant 467 is terminated 468 * added an experimental TLSv1 client implementation 469 (CONFIG_TLS=internal) that can be used instead of an external TLS 470 library, e.g., to reduce total size requirement on systems that do 471 not include any TLS library by default (this is not yet complete; 472 basic functionality is there, but certificate validation is not yet 473 included) 474 * added PeerKey handshake implementation for IEEE 802.11e 475 direct link setup (DLS) to replace STAKey handshake 476 * fixed WPA PSK update through ctrl_iface for the case where the old 477 PSK was derived from an ASCII passphrase and the new PSK is set as 478 a raw PSK (hex string) 479 * added new configuration option for identifying which network block 480 was used (id_str in wpa_supplicant.conf; included on 481 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental 482 variable in wpa_cli action scripts; in addition WPA_ID variable is 483 set to the current unique identifier that wpa_supplicant assigned 484 automatically for the network and that can be used with 485 GET_NETWORK/SET_NETWORK ctrl_iface commands) 486 * wpa_cli action script is now called only when the connect/disconnect 487 status changes or when associating with a different network 488 * fixed configuration parser not to remove CCMP from group cipher list 489 if WPA-None (adhoc) is used (pairwise=NONE in that case) 490 * fixed integrated NDIS events processing not to hang the process due 491 to a missed change in eloop_win.c API in v0.5.3 [Bug 155] 492 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK, 493 draft-clancy-emu-eap-shared-secret-00.txt) 494 * added Microsoft Visual Studio 2005 solution and project files for 495 build wpa_supplicant for Windows (see vs2005 subdirectory) 496 * eloop_win: fixed unregistration of Windows events 497 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet 498 at the end of RSN pre-authentication and added unregistration of 499 a Windows event to avoid getting eloop_win stuck with an invalid 500 handle 501 * driver_ndis: added support for selecting AP based on BSSID 502 * added new environmental variable for wpa_cli action scripts: 503 WPA_CTRL_DIR is the current control interface directory 504 * driver_ndis: added support for using NDISUIO instead of WinPcap for 505 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new 506 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build 507 wpa_supplicant without requiring WinPcap; note that using NDISUIO 508 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows 509 only one application to open the device 510 * changed NDIS driver naming to only include device GUID, e.g., 511 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap 512 specific \Device\NPF_ prefix before the GUID; the prefix is still 513 allowed for backwards compatibility, but it is not required anymore 514 when specifying the interface 515 * driver_ndis: re-initialize driver interface is the adapter is removed 516 and re-inserted [Bug 159] 517 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on 518 big endian hosts [Bug 146] 519 5202006-04-27 - v0.5.3 521 * fixed EAP-GTC response to include correct user identity when run as 522 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2) 523 * driver_ndis: Fixed encryption mode configuration for unencrypted 524 networks (some NDIS drivers ignored this, but others, e.g., Broadcom, 525 refused to associate with open networks) [Bug 106] 526 * driver_ndis: use BSSID OID polling to detect when IBSS network is 527 formed even when ndis_events code is included since some NDIS drivers 528 do not generate media connect events in IBSS mode 529 * config_winreg: allow global ctrl_interface parameter to be configured 530 in Windows registry 531 * config_winreg: added support for saving configuration data into 532 Windows registry 533 * added support for controlling network device operational state 534 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see 535 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client 536 that can use this information) 537 * driver_wext: added support for WE-21 change to SSID configuration 538 * driver_wext: fixed privacy configuration for static WEP keys mode 539 [Bug 140] 540 * added an optional driver_ops callback for MLME-SETPROTECTION.request 541 primitive 542 * added support for EAP-SAKE (no EAP method number allocated yet, so 543 this is using the same experimental type 255 as EAP-PSK) 544 * added support for dynamically loading EAP methods (.so files) instead 545 of requiring them to be statically linked in; this is disabled by 546 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information 547 on how to use this) 548 5492006-03-19 - v0.5.2 550 * do not try to use USIM APDUs when initializing PC/SC for SIM card 551 access for a network that has not enabled EAP-AKA 552 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in 553 v0.5.1 due to the new support for expanded EAP types) 554 * added support for generating EAP Expanded Nak 555 * try to fetch scan results once before requesting new scan when 556 starting up in ap_scan=1 mode (this can speed up initial association 557 a lot with, e.g., madwifi-ng driver) 558 * added support for receiving EAPOL frames from a Linux bridge 559 interface (-bbr0 on command line) 560 * fixed EAPOL re-authentication for sessions that used PMKSA caching 561 * changed EAP method registration to use a dynamic list of methods 562 instead of a static list generated at build time 563 * fixed PMKSA cache deinitialization not to use freed memory when 564 removing PMKSA entries 565 * fixed a memory leak in EAP-TTLS re-authentication 566 * reject WPA/WPA2 message 3/4 if it does not include any valid 567 WPA/RSN IE 568 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg 569 if the driver does not support SIOCSIWAUTH 570 5712006-01-29 - v0.5.1 572 * driver_test: added better support for multiple APs and STAs by using 573 a directory with sockets that include MAC address for each device in 574 the name (driver_param=test_dir=/tmp/test) 575 * added support for EAP expanded type (vendor specific EAP methods) 576 * added AP_SCAN command into ctrl_iface so that ap_scan configuration 577 option can be changed if needed 578 * wpa_cli/wpa_gui: skip non-socket files in control directory when 579 using UNIX domain sockets; this avoids selecting an incorrect 580 interface (e.g., a PID file could be in this directory, even though 581 use of this directory for something else than socket files is not 582 recommended) 583 * fixed TLS library deinitialization after RSN pre-authentication not 584 to disable TLS library for normal authentication 585 * driver_wext: Remove null-termination from SSID length if the driver 586 used it; some Linux drivers do this and they were causing problems in 587 wpa_supplicant not finding matching configuration block. This change 588 would break a case where the SSID actually ends in '\0', but that is 589 not likely to happen in real use. 590 * fixed PMKSA cache processing not to trigger deauthentication if the 591 current PMKSA cache entry is replaced with a valid new entry 592 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes 593 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or 594 ap_scan=2) 595 5962005-12-18 - v0.5.0 (beginning of 0.5.x development releases) 597 * added experimental STAKey handshake implementation for IEEE 802.11e 598 direct link setup (DLS); note: this is disabled by default in both 599 build and runtime configuration (can be enabled with CONFIG_STAKEY=y 600 and stakey=1) 601 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to 602 decrypt AT_ENCR_DATA attributes correctly 603 * fixed EAP-AKA to allow resynchronization within the same session 604 * made code closer to ANSI C89 standard to make it easier to port to 605 other C libraries and compilers 606 * started moving operating system or C library specific functions into 607 wrapper functions defined in os.h and implemented in os_*.c to make 608 code more portable 609 * wpa_supplicant can now be built with Microsoft Visual C++ 610 (e.g., with the freely available Toolkit 2003 version or Visual 611 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an 612 example makefile for nmake 613 * added support for using Windows registry for command line parameters 614 (CONFIG_MAIN=main_winsvc) and configuration data 615 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry 616 contents; this version can be run both as a Windows service and as a 617 normal application; 'wpasvc.exe app' to start as applicant, 618 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service, 619 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to 620 unregister a service 621 * made it possible to link ndis_events.exe functionality into 622 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED 623 * added better support for multiple control interface backends 624 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported 625 * fixed PC/SC code to use correct length for GSM AUTH command buffer 626 and to not use pioRecvPci with SCardTransmit() calls; these were not 627 causing visible problems with pcsc-lite, but Windows Winscard.dll 628 refused the previously used parameters; this fixes EAP-SIM and 629 EAP-AKA authentication using SIM/USIM card under Windows 630 * added new event loop implementation for Windows using 631 WaitForMultipleObject() instead of select() in order to allow waiting 632 for non-socket objects; this can be selected with 633 CONFIG_ELOOP=eloop_win in .config 634 * added support for selecting l2_packet implementation in .config 635 (CONFIG_L2_PACKET; following options are available now: linux, pcap, 636 winpcap, freebsd, none) 637 * added new l2_packet implementation for WinPcap 638 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to 639 reduce latency in EAPOL receive processing from about 100 ms to about 640 3 ms 641 * added support for EAP-FAST key derivation using other ciphers than 642 RC4-128-SHA for authentication and AES128-SHA for provisioning 643 * added support for configuring CA certificate as DER file and as a 644 configuration blob 645 * fixed private key configuration as configuration blob and added 646 support for using PKCS#12 as a blob 647 * tls_gnutls: added support for using PKCS#12 files; added support for 648 session resumption 649 * added support for loading trusted CA certificates from Windows 650 certificate store: ca_cert="cert_store://<name>", where <name> is 651 likely CA (Intermediate CA certificates) or ROOT (root certificates) 652 * added C version of ndis_events.cpp and made it possible to build this 653 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more 654 easily on cross-compilation builds 655 * added wpasvc.exe into Windows binary release; this is an alternative 656 version of wpa_supplicant.exe with configuration backend using 657 Windows registry and with the entry point designed to run as a 658 Windows service 659 * integrated ndis_events.exe functionality into wpa_supplicant.exe and 660 wpasvc.exe and removed this additional tool from the Windows binary 661 release since it is not needed anymore 662 * load winscard.dll functions dynamically when building with MinGW 663 since MinGW does not yet include winscard library 664 6652005-11-20 - v0.4.7 (beginning of 0.4.x stable releases) 666 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap 667 and WinPcap to receive frames sent to PAE group address 668 * disable EAP state machine when IEEE 802.1X authentication is not used 669 in order to get rid of bogus "EAP failed" messages 670 * fixed OpenSSL error reporting to go through all pending errors to 671 avoid confusing reports of old errors being reported at later point 672 during handshake 673 * fixed configuration file updating to not write empty variables 674 (e.g., proto or key_mgmt) that the file parser would not accept 675 * fixed ADD_NETWORK ctrl_iface command to use the same default values 676 for variables as empty network definitions read from config file 677 would get 678 * fixed EAP state machine to not discard EAP-Failure messages in many 679 cases (e.g., during TLS handshake) 680 * fixed a infinite loop in private key reading if the configured file 681 cannot be parsed successfully 682 * driver_madwifi: added support for madwifi-ng 683 * wpa_gui: do not display password/PSK field contents 684 * wpa_gui: added CA certificate configuration 685 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID 686 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if 687 the new AP is using different WPA/RSN IE 688 * use longer timeout for IEEE 802.11 association to avoid problems with 689 drivers that may take more than five second to associate 690 6912005-10-27 - v0.4.6 692 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in 693 RSN IE, but WPA IE would match with wpa_supplicant configuration 694 * added support for named configuration blobs in order to avoid having 695 to use file system for external files (e.g., certificates); 696 variables can be set to "blob://<blob name>" instead of file path to 697 use a named blob; supported fields: pac_file, client_cert, 698 private_key 699 * fixed RSN pre-authentication (it was broken in the clean up of WPA 700 state machine interface in v0.4.5) 701 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make 702 sure the driver configures broadcast decryption correctly 703 * added ca_path (and ca_path2) configuration variables that can be used 704 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the 705 system-wide trusted CA list 706 * added support for starting wpa_supplicant without a configuration 707 file (-C argument must be used to set ctrl_interface parameter for 708 this case; in addition, -p argument can be used to provide 709 driver_param; these new arguments can also be used with a 710 configuration to override the values from the configuration) 711 * added global control interface that can be optionally used for adding 712 and removing network interfaces dynamically (-g command line argument 713 for both wpa_supplicant and wpa_cli) without having to restart 714 wpa_supplicant process 715 * wpa_gui: 716 - try to save configuration whenever something is modified 717 - added WEP key configuration 718 - added possibility to edit the current network configuration 719 * driver_ndis: fixed driver polling not to increase frequency on each 720 received EAPOL frame due to incorrectly cancelled timeout 721 * added simple configuration file examples (in examples subdirectory) 722 * fixed driver_wext.c to filter wireless events based on ifindex to 723 avoid interfaces receiving events from other interfaces 724 * delay sending initial EAPOL-Start couple of seconds to speed up 725 authentication for the most common case of Authenticator starting 726 EAP authentication immediately after association 727 7282005-09-25 - v0.4.5 729 * added a workaround for clearing keys with ndiswrapper to allow 730 roaming from WPA enabled AP to plaintext one 731 * added docbook documentation (doc/docbook) that can be used to 732 generate, e.g., man pages 733 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for 734 PF_PACKET in order to prepare for network devices that do not use 735 Ethernet headers (e.g., network stack with native IEEE 802.11 frames) 736 * use receipt of EAPOL-Key frame as a lower layer success indication 737 for EAP state machine to allow recovery from dropped EAP-Success 738 frame 739 * cleaned up internal EAPOL frame processing by not including link 740 layer (Ethernet) header during WPA and EAPOL/EAP processing; this 741 header is added only when transmitted the frame; this makes it easier 742 to use wpa_supplicant on link layers that use different header than 743 Ethernet 744 * updated EAP-PSK to use draft 9 by default since this can now be 745 tested with hostapd; removed support for draft 3, including 746 server_nai configuration option from network blocks 747 * driver_wired: add PAE address to the multicast address list in order 748 to be able to receive EAPOL frames with drivers that do not include 749 these multicast addresses by default 750 * driver_wext: add support for WE-19 751 * added support for multiple configuration backends (CONFIG_BACKEND 752 option); currently, only 'file' is supported (i.e., the format used 753 in wpa_supplicant.conf) 754 * added support for updating configuration ('wpa_cli save_config'); 755 this is disabled by default and can be enabled with global 756 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli 757 and wpa_gui to store the configuration changes in a permanent store 758 * added GET_NETWORK ctrl_iface command 759 (e.g., 'wpa_cli get_network 0 ssid') 760 7612005-08-21 - v0.4.4 762 * replaced OpenSSL patch for EAP-FAST support 763 (openssl-tls-extensions.patch) with a more generic and correct 764 patch (the new patch is not compatible with the previous one, so the 765 OpenSSL library will need to be patched with the new patch in order 766 to be able to build wpa_supplicant with EAP-FAST support) 767 * added support for using Windows certificate store (through CryptoAPI) 768 for client certificate and private key operations (EAP-TLS) 769 (see wpa_supplicant.conf for more information on how to configure 770 this with private_key) 771 * ported wpa_gui to Windows 772 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be 773 built with the open source version of the Qt4 for Windows 774 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used 775 with drivers that do not support WPA 776 * ndis_events: fixed Windows 2000 support 777 * added support for enabling/disabling networks from the list of all 778 configured networks ('wpa_cli enable_network <network id>' and 779 'wpa_cli disable_network <network id>') 780 * added support for adding and removing network from the current 781 configuration ('wpa_cli add_network' and 'wpa_cli remove_network 782 <network id>'); added networks are disabled by default and they can 783 be enabled with enable_network command once the configuration is done 784 for the new network; note: configuration file is not yet updated, so 785 these new networks are lost when wpa_supplicant is restarted 786 * added support for setting network configuration parameters through 787 the control interface, for example: 788 wpa_cli set_network 0 ssid "\"my network\"" 789 * fixed parsing of strings that include both " and # within double 790 quoted area (e.g., "start"#end") 791 * added EAP workaround for PEAP session resumption: allow outer, 792 i.e., not tunneled, EAP-Success to terminate session since; this can 793 be disabled with eap_workaround=0 794 (this was allowed for PEAPv1 before, but now it is also allowed for 795 PEAPv0 since at least one RADIUS authentication server seems to be 796 doing this for PEAPv0, too) 797 * wpa_gui: added preliminary support for adding new networks to the 798 wpa_supplicant configuration (double click on the scan results to 799 open network configuration) 800 8012005-06-26 - v0.4.3 802 * removed interface for external EAPOL/EAP supplicant (e.g., 803 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required 804 anymore and is unlikely to be used by anyone 805 * driver_ndis: fixed WinPcap 3.0 support 806 * fixed build with CONFIG_DNET_PCAP=y on Linux 807 * l2_packet: moved different implementations into separate files 808 (l2_packet_*.c) 809 8102005-06-12 - v0.4.2 811 * driver_ipw: updated driver structures to match with ipw2200-1.0.4 812 (note: ipw2100-1.1.0 is likely to require an update to work with 813 this) 814 * added support for using ap_scan=2 mode with multiple network blocks; 815 wpa_supplicant will go through the networks one by one until the 816 driver reports a successful association; this uses the same order for 817 networks as scan_ssid=1 scans, i.e., the priority field is ignored 818 and the network block order in the file is used instead 819 * fixed a potential issue in RSN pre-authentication ending up using 820 freed memory if pre-authentication times out 821 * added support for matching alternative subject name extensions of the 822 authentication server certificate; new configuration variables 823 altsubject_match and altsubject_match2 824 * driver_ndis: added support for IEEE 802.1X authentication with wired 825 NDIS drivers 826 * added support for querying private key password (EAP-TLS) through the 827 control interface (wpa_cli/wpa_gui) if one is not included in the 828 configuration file 829 * driver_broadcom: fixed couple of memory leaks in scan result 830 processing 831 * EAP-PAX is now registered as EAP type 46 832 * fixed EAP-PAX MAC calculation 833 * fixed EAP-PAX CK and ICK key derivation 834 * added support for using password with EAP-PAX (as an alternative to 835 entering key with eappsk); SHA-1 hash of the password will be used as 836 the key in this case 837 * added support for arbitrary driver interface parameters through the 838 configuration file with a new driver_param field; this adds a new 839 driver_ops function set_param() 840 * added possibility to override l2_packet module with driver interface 841 API (new send_eapol handler); this can be used to implement driver 842 specific TX/RX functions for EAPOL frames 843 * fixed ctrl_interface_group processing for the case where gid is 844 entered as a number, not group name 845 * driver_test: added support for testing hostapd with wpa_supplicant 846 by using test driver interface without any kernel drivers or network 847 cards 848 8492005-05-22 - v0.4.1 850 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL 851 packets to be encrypted; this was apparently broken by the changed 852 ioctl order in v0.4.0 853 * driver_madwifi: added preliminary support for compiling against 'BSD' 854 branch of madwifi CVS tree 855 * added support for EAP-MSCHAPv2 password retries within the same EAP 856 authentication session 857 * added support for password changes with EAP-MSCHAPv2 (used when the 858 password has expired) 859 * added support for reading additional certificates from PKCS#12 files 860 and adding them to the certificate chain 861 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys 862 were used 863 * fixed a possible double free in EAP-TTLS fast-reauthentication when 864 identity or password is entered through control interface 865 * display EAP Notification messages to user through control interface 866 with "CTRL-EVENT-EAP-NOTIFICATION" prefix 867 * added GUI version of wpa_cli, wpa_gui; this is not build 868 automatically with 'make'; use 'make wpa_gui' to build (this requires 869 Qt development tools) 870 * added 'disconnect' command to control interface for setting 871 wpa_supplicant in state where it will not associate before 872 'reassociate' command has been used 873 * added support for selecting a network from the list of all configured 874 networks ('wpa_cli select_network <network id>'; this disabled all 875 other networks; to re-enable, 'wpa_cli select_network any') 876 * added support for getting scan results through control interface 877 * added EAP workaround for PEAPv1 session resumption: allow outer, 878 i.e., not tunneled, EAP-Success to terminate session since; this can 879 be disabled with eap_workaround=0 880 8812005-04-25 - v0.4.0 (beginning of 0.4.x development releases) 882 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be 883 used to reduce the size of the wpa_supplicant considerably if 884 debugging code is not needed 885 * fixed EAPOL-Key validation to drop packets with invalid Key Data 886 Length; such frames could have crashed wpa_supplicant due to buffer 887 overflow 888 * added support for wired authentication (IEEE 802.1X on wired 889 Ethernet); driver interface 'wired' 890 * obsoleted set_wpa() handler in the driver interface API (it can be 891 replaced by moving enable/disable functionality into init()/deinit()) 892 (calls to set_wpa() are still present for backwards compatibility, 893 but they may be removed in the future) 894 * driver_madwifi: fixed association in plaintext mode 895 * modified the EAP workaround that accepts EAP-Success with incorrect 896 Identifier to be even less strict about verification in order to 897 interoperate with some authentication servers 898 * added support for sending TLS alerts 899 * added support for 'any' SSID wildcard; if ssid is not configured or 900 is set to an empty string, any SSID will be accepted for non-WPA AP 901 * added support for asking PIN (for SIM) from frontends (e.g., 902 wpa_cli); if a PIN is needed, but not included in the configuration 903 file, a control interface request is sent and EAP processing is 904 delayed until the PIN is available 905 * added support for using external devices (e.g., a smartcard) for 906 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config); 907 new wpa_supplicant.conf variables: 908 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path 909 - network: engine, engine_id, key_id 910 * added experimental support for EAP-PAX 911 * added monitor mode for wpa_cli (-a<path to a program to run>) that 912 allows external commands (e.g., shell scripts) to be run based on 913 wpa_supplicant events, e.g., when authentication has been completed 914 and data connection is ready; other related wpa_cli arguments: 915 -B (run in background), -P (write PID file); wpa_supplicant has a new 916 command line argument (-W) that can be used to make it wait until a 917 control interface command is received in order to avoid missing 918 events 919 * added support for opportunistic WPA2 PMKSA key caching (disabled by 920 default, can be enabled with proactive_key_caching=1) 921 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where 922 Authenticator rejects PMKSA caching attempt and the driver is not 923 using assoc_info events 924 * added -P<pid file> argument for wpa_supplicant to write the current 925 process id into a file 926 9272005-02-12 - v0.3.7 (beginning of 0.3.x stable releases) 928 * added new phase1 option parameter, include_tls_length=1, to force 929 wpa_supplicant to add TLS Message Length field to all TLS messages 930 even if the packet is not fragmented; this may be needed with some 931 authentication servers 932 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when 933 using drivers that take care of AP selection (e.g., when using 934 ap_scan=2) 935 * fixed reprocessing of pending request after ctrl_iface requests for 936 identity/password/otp 937 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of 938 EAP-PEAP and EAP-TTLS 939 * all drivers using driver_wext: set interface up and select Managed 940 mode when starting wpa_supplicant; set interface down when exiting 941 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both 942 ipw2100 and ipw2200; please note that this also changed the 943 configuration variable in .config to CONFIG_DRIVER_IPW 944 9452005-01-24 - v0.3.6 946 * fixed a busy loop introduced in v0.3.5 for scan result processing 947 when no matching AP is found 948 9492005-01-23 - v0.3.5 950 * added a workaround for an interoperability issue with a Cisco AP 951 when using WPA2-PSK 952 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as 953 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow 954 retransmission of dropped frames) 955 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version 956 (e.g., segfault when processing EAPOL-Key frames) 957 * fixed EAP workaround and fast reauthentication configuration for 958 RSN pre-authentication; previously these were disabled and 959 pre-authentication would fail if the used authentication server 960 requires EAP workarounds 961 * added support for blacklisting APs that fail or timeout 962 authentication in ap_scan=1 mode so that all APs are tried in cases 963 where the ones with strongest signal level are failing authentication 964 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS 965 authentication attempt 966 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded 967 in the previous authentication (previously, only Phase 1 success was 968 verified) 969 9702005-01-09 - v0.3.4 971 * added preliminary support for IBSS (ad-hoc) mode configuration 972 (mode=1 in network block); this included a new key_mgmt mode 973 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no 974 key management; see wpa_supplicant.conf for more details and an 975 example on how to configure this (note: this is currently implemented 976 only for driver_hostapd.c, but the changes should be trivial to add 977 in associate() handler for other drivers, too (assuming the driver 978 supports WPA-None) 979 * added preliminary port for native Windows (i.e., no cygwin) using 980 mingw 981 9822005-01-02 - v0.3.3 983 * added optional support for GNU Readline and History Libraries for 984 wpa_cli (CONFIG_READLINE) 985 * cleaned up EAP state machine <-> method interface and number of 986 small problems with error case processing not terminating on 987 EAP-Failure but waiting for timeout 988 * added couple of workarounds for interoperability issues with a 989 Cisco AP when using WPA2 990 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt); 991 Note: This requires a patch for openssl to add support for TLS 992 extensions and number of workarounds for operations without 993 certificates. Proof of concept type of experimental patch is 994 included in openssl-tls-extensions.patch. 995 9962004-12-19 - v0.3.2 997 * fixed private key loading for cases where passphrase is not set 998 * fixed Windows/cygwin L2 packet handler freeing; previous version 999 could cause a segfault when RSN pre-authentication was completed 1000 * added support for PMKSA caching with drivers that generate RSN IEs 1001 (e.g., NDIS); currently, this is only implemented in driver_ndis.c, 1002 but similar code can be easily added to driver_ndiswrapper.c once 1003 ndiswrapper gets full support for RSN PMKSA caching 1004 * improved recovery from PMKID mismatches by requesting full EAP 1005 authentication in case of failed PMKSA caching attempt 1006 * driver_ndis: added support for NDIS NdisMIncidateStatus() events 1007 (this requires that ndis_events is ran while wpa_supplicant is 1008 running) 1009 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys 1010 * added support for driver interfaces to replace the interface name 1011 based on driver/OS specific mapping, e.g., in case of driver_ndis, 1012 this allows the beginning of the adapter description to be used as 1013 the interface name 1014 * added support for CR+LF (Windows-style) line ends in configuration 1015 file 1016 * driver_ndis: enable radio before starting scanning, disable radio 1017 when exiting 1018 * modified association event handler to set portEnabled = FALSE before 1019 clearing port Valid in order to reset EAP state machine and avoid 1020 problems with new authentication getting ignored because of state 1021 machines ending up in AUTHENTICATED/SUCCESS state based on old 1022 information 1023 * added support for driver events to add PMKID candidates in order to 1024 allow drivers to give priority to most likely roaming candidates 1025 * driver_hostap: moved PrivacyInvoked configuration to associate() 1026 function so that this will not be set for plaintext connections 1027 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver 1028 interface can distinguish plaintext and IEEE 802.1X (no WPA) 1029 authentication 1030 * fixed static WEP key configuration to use broadcast/default type for 1031 all keys (previously, the default TX key was configured as pairwise/ 1032 unicast key) 1033 * driver_ndis: added legacy WPA capability detection for non-WPA2 1034 drivers 1035 * added support for setting static WEP keys for IEEE 802.1X without 1036 dynamic WEP keying (eapol_flags=0) 1037 10382004-12-12 - v0.3.1 1039 * added support for reading PKCS#12 (PFX) files (as a replacement for 1040 PEM/DER) to get certificate and private key (CONFIG_PKCS12) 1041 * fixed compilation with CONFIG_PCSC=y 1042 * added new ap_scan mode, ap_scan=2, for drivers that take care of 1043 association, but need to be configured with security policy and SSID, 1044 e.g., ndiswrapper and NDIS driver; this mode should allow such 1045 drivers to work with hidden SSIDs and optimized roaming; when 1046 ap_scan=2 is used, only the first network block in the configuration 1047 file is used and this configuration should have explicit security 1048 policy (i.e., only one option in the lists) for key_mgmt, pairwise, 1049 group, proto variables 1050 * added experimental port of wpa_supplicant for Windows 1051 - driver_ndis.c driver interface (NDIS OIDs) 1052 - currently, this requires cygwin and WinPcap 1053 - small utility, win_if_list, can be used to get interface name 1054 * control interface can now be removed at build time; add 1055 CONFIG_CTRL_IFACE=y to .config to maintain old functionality 1056 * optional Xsupplicant interface can now be removed at build time; 1057 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back) 1058 * added auth_alg to driver interface associate() parameters to make it 1059 easier for drivers to configure authentication algorithm as part of 1060 the association 1061 10622004-12-05 - v0.3.0 (beginning of 0.3.x development releases) 1063 * driver_broadcom: added new driver interface for Broadcom wl.o driver 1064 (a generic driver for Broadcom IEEE 802.11a/g cards) 1065 * wpa_cli: fixed parsing of -p <path> command line argument 1066 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS 1067 ACK, not tunneled EAP-Success (of which only the first byte was 1068 actually send due to a bug in previous code); this seems to 1069 interoperate with most RADIUS servers that implements PEAPv1 1070 * PEAPv1: added support for terminating PEAP authentication on tunneled 1071 EAP-Success message; this can be configured by adding 1072 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf 1073 (some RADIUS servers require this whereas others require a tunneled 1074 reply 1075 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to 1076 the old label for key derivation; previously, the default was 1, 1077 but it looks like most existing PEAPv1 implementations use the old 1078 label which is thus more suitable default option 1079 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt) 1080 * fixed parsing of wep_tx_keyidx 1081 * added support for configuring list of allowed Phase 2 EAP types 1082 (for both EAP-PEAP and EAP-TTLS) instead of only one type 1083 * added support for configuring IEEE 802.11 authentication algorithm 1084 (auth_alg; mainly for using Shared Key authentication with static 1085 WEP keys) 1086 * added support for EAP-AKA (with UMTS SIM) 1087 * fixed couple of errors in PCSC handling that could have caused 1088 random-looking errors for EAP-SIM 1089 * added support for EAP-SIM pseudonyms and fast re-authentication 1090 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS 1091 session resumption) 1092 * added support for EAP-SIM with two challanges 1093 (phase1="sim_min_num_chal=3" can be used to require three challenges) 1094 * added support for configuring DH/DSA parameters for an ephemeral DH 1095 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters 1096 dh_file and dh_file2 (phase 2); this adds support for using DSA keys 1097 and optional DH key exchange to achieve forward secracy with RSA keys 1098 * added support for matching subject of the authentication server 1099 certificate with a substring when using EAP-TLS/PEAP/TTLS; new 1100 configuration variables subject_match and subject_match2 1101 * changed SSID configuration in driver_wext.c (used by many driver 1102 interfaces) to use ssid_len+1 as the length for SSID since some Linux 1103 drivers expect this 1104 * fixed couple of unaligned reads in scan result parsing to fix WPA 1105 connection on some platforms (e.g., ARM) 1106 * added driver interface for Intel ipw2100 driver 1107 * added support for LEAP with WPA 1108 * added support for larger scan results report (old limit was 4 kB of 1109 data, i.e., about 35 or so APs) when using Linux wireless extensions 1110 v17 or newer 1111 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start 1112 only if there is a PMKSA cache entry for the current AP 1113 * fixed error handling for case where reading of scan results fails: 1114 must schedule a new scan or wpa_supplicant will remain waiting 1115 forever 1116 * changed debug output to remove shared password/key material by 1117 default; all key information can be included with -K command line 1118 argument to match the previous behavior 1119 * added support for timestamping debug log messages (disabled by 1120 default, can be enabled with -t command line argument) 1121 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104 1122 if keys are not configured to be used; this fixes IEEE 802.1X mode 1123 with drivers that use this information to configure whether Privacy 1124 bit can be in Beacon frames (e.g., ndiswrapper) 1125 * avoid clearing driver keys if no keys have been configured since last 1126 key clear request; this seems to improve reliability of group key 1127 handshake for ndiswrapper & NDIS driver which seems to be suffering 1128 of some kind of timing issue when the keys are cleared again after 1129 association 1130 * changed driver interface API: 1131 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which 1132 version is being used (now, this is set to 2; previously, it was 1133 not defined) 1134 - pass pointer to private data structure to all calls 1135 - the new API is not backwards compatible; all in-tree driver 1136 interfaces has been converted to the new API 1137 * added support for controlling multiple interfaces (radios) per 1138 wpa_supplicant process; each interface needs to be listed on the 1139 command line (-c, -i, -D arguments) with -N as a separator 1140 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi) 1141 * added a workaround for EAP servers that incorrectly use same Id for 1142 sequential EAP packets 1143 * changed libpcap/libdnet configuration to use .config variable, 1144 CONFIG_DNET_PCAP, instead of requiring Makefile modification 1145 * improved downgrade attack detection in IE verification of msg 3/4: 1146 verify both WPA and RSN IEs, if present, not only the selected one; 1147 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or 1148 Probe Response frame, and RSN is enabled in wpa_supplicant 1149 configuration 1150 * fixed WPA msg 3/4 processing to allow Key Data field contain other 1151 IEs than just one WPA IE 1152 * added support for FreeBSD and driver interface for the BSD net80211 1153 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the 1154 required kernel mods have not yet been committed 1155 * made EAP workarounds configurable; enabled by default, can be 1156 disabled with network block option eap_workaround=0 1157 11582004-07-17 - v0.2.4 (beginning of 0.2.x stable releases) 1159 * resolved couple of interoperability issues with EAP-PEAPv1 and 1160 Phase 2 (inner EAP) fragment reassembly 1161 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the 1162 AP is using non-zero key index for the unicast key and key index zero 1163 for the broadcast key 1164 * driver_hostap: fixed IEEE 802.1X WEP key updates and 1165 re-authentication by allowing unencrypted EAPOL frames when not using 1166 WPA 1167 * added a new driver interface, 'wext', which uses only standard, 1168 driver independent functionality in Linux wireless extensions; 1169 currently, this can be used only for non-WPA IEEE 802.1X mode, but 1170 eventually, this is to be extended to support full WPA/WPA2 once 1171 Linux wireless extensions get support for this 1172 * added support for mode in which the driver is responsible for AP 1173 scanning and selection; this is disabled by default and can be 1174 enabled with global ap_scan=0 variable in wpa_supplicant.conf; 1175 this mode can be used, e.g., with generic 'wext' driver interface to 1176 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver 1177 supporting wireless extensions. 1178 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g., 1179 operation with an AP that does not include SSID in the Beacon frames) 1180 * added support for new EAP authentication methods: 1181 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP 1182 * added support for asking one-time-passwords from frontends (e.g., 1183 wpa_cli); this 'otp' command works otherwise like 'password' command, 1184 but the password is used only once and the frontend will be asked for 1185 a new password whenever a request from authenticator requires a 1186 password; this can be used with both EAP-OTP and EAP-GTC 1187 * changed wpa_cli to automatically re-establish connection so that it 1188 does not need to be re-started when wpa_supplicant is terminated and 1189 started again 1190 * improved user data (identity/password/otp) requests through 1191 frontends: process pending EAPOL packets after getting new 1192 information so that full authentication does not need to be 1193 restarted; in addition, send pending requests again whenever a new 1194 frontend is attached 1195 * changed control frontends to use a new directory for socket files to 1196 make it easier for wpa_cli to automatically select between interfaces 1197 and to provide access control for the control interface; 1198 wpa_supplicant.conf: ctrl_interface is now a path 1199 (/var/run/wpa_supplicant is the recommended path) and 1200 ctrl_interface_group can be used to select which group gets access to 1201 the control interface; 1202 wpa_cli: by default, try to connect to the first interface available 1203 in /var/run/wpa_supplicant; this path can be overriden with -p option 1204 and an interface can be selected with -i option (i.e., in most common 1205 cases, wpa_cli does not need to get any arguments) 1206 * added support for LEAP 1207 * added driver interface for Linux ndiswrapper 1208 * added priority option for network blocks in the configuration file; 1209 this allows networks to be grouped based on priority (the scan 1210 results are searched for matches with network blocks in this order) 1211 12122004-06-20 - v0.2.3 1213 * sort scan results to improve AP selection 1214 * fixed control interface socket removal for some error cases 1215 * improved scan requesting and authentication timeout 1216 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and 1217 TLS processing 1218 * PEAP version can now be forced with phase1="peapver=<ver>" 1219 (mostly for testing; by default, the highest version supported by 1220 both the Supplicant and Authentication Server is selected 1221 automatically) 1222 * added support for madwifi driver (Atheros ar521x) 1223 * added a workaround for cases where AP sets Install Tx/Rx bit for 1224 WPA Group Key messages when pairwise keys are used (without this, 1225 the Group Key would be used for Tx and the AP would drop frames 1226 from the station) 1227 * added GSM SIM/USIM interface for GSM authentication algorithm for 1228 EAP-SIM; this requires pcsc-lite 1229 * added support for ATMEL AT76C5XXx driver 1230 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator 1231 does not include key data in the EAPOL-Key frame (i.e., part of 1232 EAP keying material is used as data encryption key) 1233 * added support for using plaintext and static WEP networks 1234 (key_mgmt=NONE) 1235 12362004-05-31 - v0.2.2 1237 * added support for new EAP authentication methods: 1238 EAP-TTLS/EAP-MD5-Challenge 1239 EAP-TTLS/EAP-GTC 1240 EAP-TTLS/EAP-MSCHAPv2 1241 EAP-TTLS/EAP-TLS 1242 EAP-TTLS/MSCHAPv2 1243 EAP-TTLS/MSCHAP 1244 EAP-TTLS/PAP 1245 EAP-TTLS/CHAP 1246 EAP-PEAP/TLS 1247 EAP-PEAP/GTC 1248 EAP-PEAP/MD5-Challenge 1249 EAP-GTC 1250 EAP-SIM (not yet complete; needs GSM/SIM authentication interface) 1251 * added support for anonymous identity (to be used when identity is 1252 sent in plaintext; real identity will be used within TLS protected 1253 tunnel (e.g., with EAP-TTLS) 1254 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli 1255 * added support for requesting identity and password information using 1256 control interface; in other words, the password for EAP-PEAP or 1257 EAP-TTLS does not need to be included in the configuration file since 1258 a frontand (e.g., wpa_cli) can ask it from the user 1259 * improved RSN pre-authentication to use a candidate list and process 1260 all candidates from each scan; not only one per scan 1261 * fixed RSN IE and WPA IE capabilities field parsing 1262 * ignore Tx bit in GTK IE when Pairwise keys are used 1263 * avoid making new scan requests during IEEE 802.1X negotiation 1264 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant 1265 with TLS support (this replaces the included implementation with 1266 library code to save about 8 kB since the library code is needed 1267 anyway for TLS) 1268 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support 1269 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config) 1270 12712004-05-06 - v0.2.1 1272 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1) 1273 Supplicant 1274 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1] 1275 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf] 1276 - EAP-MD5 (cannot be used with WPA-RADIUS) 1277 [draft-ietf-eap-rfc2284bis-09.txt] 1278 - EAP-TLS [RFC 2716] 1279 - EAP-MSCHAPv2 (currently used only with EAP-PEAP) 1280 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt] 1281 [draft-kamath-pppext-eap-mschapv2-00.txt] 1282 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by 1283 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey) 1284 - new configuration file options: eap, identity, password, ca_cert, 1285 client_cert, privatekey, private_key_passwd 1286 - Xsupplicant is not required anymore, but it can be used by 1287 disabling the internal IEEE 802.1X Supplicant with -e command line 1288 option 1289 - this code is not included in the default build; Makefile need to 1290 be edited for this (uncomment lines for selected functionality) 1291 - EAP-TLS and EAP-PEAP require openssl libraries 1292 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..) 1293 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys 1294 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X 1295 EAPOL-Key frames instead of WPA key handshakes) 1296 * added support for IEEE 802.11i/RSN (WPA2) 1297 - improved PTK Key Handshake 1298 - PMKSA caching, pre-authentication 1299 * fixed wpa_supplicant to ignore possible extra data after WPA 1300 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using 1301 TPTK' error from message 3 of 4-Way Handshake in case the AP 1302 includes extra data after the EAPOL-Key) 1303 * added interface for external programs (frontends) to control 1304 wpa_supplicant 1305 - CLI example (wpa_cli) with interactive mode and command line 1306 mode 1307 - replaced SIGUSR1 status/statistics with the new control interface 1308 * made some feature compile time configurable 1309 - .config file for make 1310 - driver interfaces (hostap, hermes, ..) 1311 - EAPOL/EAP functions 1312 13132004-02-15 - v0.2.0 1314 * Initial version of wpa_supplicant 1315
