1ChangeLog for wpa_supplicant 2 32009-02-15 - v0.6.8 4 * increased wpa_cli ping interval to 5 seconds and made this 5 configurable with a new command line options (-G<seconds>) 6 * fixed scan buffer processing with WEXT to handle up to 65535 7 byte result buffer (previously, limited to 32768 bytes) 8 92009-01-06 - v0.6.7 10 * added support for Wi-Fi Protected Setup (WPS) 11 (wpa_supplicant can now be configured to act as a WPS Enrollee to 12 enroll credentials for a network using PIN and PBC methods; in 13 addition, wpa_supplicant can act as a wireless WPS Registrar to 14 configure an AP); WPS support can be enabled by adding CONFIG_WPS=y 15 into .config and setting the runtime configuration variables in 16 wpa_supplicant.conf (see WPS section in the example configuration 17 file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to 18 manage WPS negotiation; see README-WPS for more details 19 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf) 20 * added support for using driver_test over UDP socket 21 * fixed PEAPv0 Cryptobinding interoperability issue with Windows Server 22 2008 NPS; optional cryptobinding is now enabled (again) by default 23 * fixed PSK editing in wpa_gui 24 * changed EAP-GPSK to use the IANA assigned EAP method type 51 25 * added a Windows installer that includes WinPcap and all the needed 26 DLLs; in addition, it set up the registry automatically so that user 27 will only need start wpa_gui to get prompted to start the wpasvc 28 servide and add a new interface if needed through wpa_gui dialog 29 * updated management frame protection to use IEEE 802.11w/D7.0 30 312008-11-23 - v0.6.6 32 * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA 33 (can be used to simulate test SIM/USIM card with a known private key; 34 enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config 35 and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration) 36 * added a new network configuration option, wpa_ptk_rekey, that can be 37 used to enforce frequent PTK rekeying, e.g., to mitigate some attacks 38 against TKIP deficiencies 39 * added an optional mitigation mechanism for certain attacks against 40 TKIP by delaying Michael MIC error reports by a random amount of time 41 between 0 and 60 seconds; this can be enabled with a build option 42 CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config 43 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits, 44 not bytes 45 * updated OpenSSL code for EAP-FAST to use an updated version of the 46 session ticket overriding API that was included into the upstream 47 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is 48 needed with that version anymore) 49 * updated userspace MLME instructions to match with the current Linux 50 mac80211 implementation; please also note that this can only be used 51 with driver_nl80211.c (the old code from driver_wext.c was removed) 52 * added support (Linux only) for RoboSwitch chipsets (often found in 53 consumer grade routers); driver interface 'roboswitch' 54 * fixed canceling of PMKSA caching when using drivers that generate 55 RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know 56 about 57 582008-11-01 - v0.6.5 59 * added support for SHA-256 as X.509 certificate digest when using the 60 internal X.509/TLSv1 implementation 61 * updated management frame protection to use IEEE 802.11w/D6.0 62 * added support for using SHA256-based stronger key derivation for WPA2 63 (IEEE 802.11w) 64 * fixed FT (IEEE 802.11r) authentication after a failed association to 65 use correct FTIE 66 * added support for configuring Phase 2 (inner/tunneled) authentication 67 method with wpa_gui-qt4 68 692008-08-10 - v0.6.4 70 * added support for EAP Sequences in EAP-FAST Phase 2 71 * added support for using TNC with EAP-FAST 72 * added driver_ps3 for the PS3 Linux wireless driver 73 * added support for optional cryptobinding with PEAPv0 74 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to 75 allow fallback to full handshake if server rejects PAC-Opaque 76 * added fragmentation support for EAP-TNC 77 * added support for parsing PKCS #8 formatted private keys into the 78 internal TLS implementation (both PKCS #1 RSA key and PKCS #8 79 encapsulated RSA key can now be used) 80 * added option of using faster, but larger, routines in the internal 81 LibTomMath (for internal TLS implementation) to speed up DH and RSA 82 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y) 83 * fixed race condition between disassociation event and group key 84 handshake to avoid getting stuck in incorrect state [Bug 261] 85 * fixed opportunistic key caching (proactive_key_caching) 86 872008-02-22 - v0.6.3 88 * removed 'nai' and 'eappsk' network configuration variables that were 89 previously used for configuring user identity and key for EAP-PSK, 90 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the 91 replacement for 'nai' (if old configuration used a separate 92 'identity' value, that would now be configured as 93 'anonymous_identity'). 'password' field is now used as the 94 replacement for 'eappsk' (it can also be set using hexstring to 95 present random binary data) 96 * removed '-w' command line parameter (wait for interface to be added, 97 if needed); cleaner way of handling this functionality is to use an 98 external mechanism (e.g., hotplug scripts) that start wpa_supplicant 99 when an interface is added 100 * updated FT support to use the latest draft, IEEE 802.11r/D9.0 101 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for 102 indicating when new scan results become available 103 * added new ctrl_iface command, BSS, to allow scan results to be 104 fetched without hitting the message size limits (this command 105 can be used to iterate through the scan results one BSS at the time) 106 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION 107 attributes in EAP-SIM Start/Response when using fast reauthentication 108 * fixed EAPOL not to end up in infinite loop when processing dynamic 109 WEP keys with IEEE 802.1X 110 * fixed problems in getting NDIS events from WMI on Windows 2000 111 1122008-01-01 - v0.6.2 113 * added support for Makefile builds to include debug-log-to-a-file 114 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line) 115 * fixed EAP-SIM and EAP-AKA message parser to validate attribute 116 lengths properly to avoid potential crash caused by invalid messages 117 * added data structure for storing allocated buffers (struct wpabuf); 118 this does not affect wpa_supplicant usage, but many of the APIs 119 changed and various interfaces (e.g., EAP) is not compatible with old 120 versions 121 * added support for protecting EAP-AKA/Identity messages with 122 AT_CHECKCODE (optional feature in RFC 4187) 123 * added support for protected result indication with AT_RESULT_IND for 124 EAP-SIM and EAP-AKA (phase1="result_ind=1") 125 * added driver_wext workaround for race condition between scanning and 126 association with drivers that take very long time to scan all 127 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now 128 using a longer hardcoded timeout for the scan if the driver supports 129 notifications for scan completion (SIOCGIWSCAN event); this helps, 130 e.g., in cases where wpa_supplicant and madwifi driver ended up in 131 loop where the driver did not even try to associate 132 * stop EAPOL timer tick when no timers are in use in order to reduce 133 power consumption (no need to wake up the process once per second) 134 [Bug 237] 135 * added support for privilege separation (run only minimal part of 136 wpa_supplicant functionality as root and rest as unprivileged, 137 non-root process); see 'Privilege separation' in README for details; 138 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y 139 in .config 140 * changed scan results data structure to include all information 141 elements to make it easier to support new IEs; old get_scan_result() 142 driver_ops is still supported for backwards compatibility (results 143 are converted internally to the new format), but all drivers should 144 start using the new get_scan_results2() to make them more likely to 145 work with new features 146 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4 147 application, i.e., it does not require Qt3Support anymore; Windows 148 binary of wpa_gui.exe is now from this directory and only requires 149 QtCore4.dll and QtGui4.dll libraries 150 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs 151 available as a separate package to make wpa_gui installation easier: 152 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip 153 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt); 154 only shared key/password authentication is supported in this version 155 1562007-11-24 - v0.6.1 157 * added support for configuring password as NtPasswordHash 158 (16-byte MD4 hash of password) in hash:<32 hex digits> format 159 * added support for fallback from abbreviated TLS handshake to 160 full handshake when using EAP-FAST (e.g., due to an expired 161 PAC-Opaque) 162 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 163 draft (draft-ietf-emu-eap-gpsk-07.txt) 164 * added support for drivers that take care of RSN 4-way handshake 165 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and 166 WPA_ALG_PMK in set_key) 167 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in 168 .config); this version supports only ap_scan=2 mode and allow the 169 driver to take care of the 4-way handshake 170 * fixed a buffer overflow in parsing TSF from scan results when using 171 driver_wext.c with a driver that includes the TSF (e.g., iwl4965) 172 [Bug 232] 173 * updated FT support to use the latest draft, IEEE 802.11r/D8.0 174 * fixed an integer overflow issue in the ASN.1 parser used by the 175 (experimental) internal TLS implementation to avoid a potential 176 buffer read overflow 177 * fixed a race condition with -W option (wait for a control interface 178 monitor before starting) that could have caused the first messages to 179 be lost 180 * added support for processing TNCC-TNCS-Messages to report 181 recommendation (allow/none/isolate) when using TNC [Bug 243] 182 1832007-05-28 - v0.6.0 184 * added network configuration parameter 'frequency' for setting 185 initial channel for IBSS (adhoc) networks 186 * added experimental IEEE 802.11r/D6.0 support 187 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48 188 * updated EAP-PSK to use the IANA-allocated EAP type 47 189 * fixed EAP-PAX key derivation 190 * fixed EAP-PSK bit ordering of the Flags field 191 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in 192 tunnelled identity request (previously, the identifier from the outer 193 method was used, not the tunnelled identifier which could be 194 different) 195 * added support for fragmentation of outer TLS packets during Phase 2 196 of EAP-PEAP/TTLS/FAST 197 * fixed EAP-TTLS AVP parser processing for too short AVP lengths 198 * added support for EAP-FAST authentication with inner methods that 199 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported 200 for PAC provisioning) 201 * added support for authenticated EAP-FAST provisioning 202 * added support for configuring maximum number of EAP-FAST PACs to 203 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string) 204 * added support for storing EAP-FAST PACs in binary format 205 (fast_pac_format=binary in phase1 string) 206 * fixed dbus ctrl_iface to validate message interface before 207 dispatching to avoid a possible segfault [Bug 190] 208 * fixed PeerKey key derivation to use the correct PRF label 209 * updated Windows binary build to link against OpenSSL 0.9.8d and 210 added support for EAP-FAST 211 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 212 draft (draft-ietf-emu-eap-gpsk-04.txt) 213 * fixed EAP-AKA Notification processing to allow Notification to be 214 processed after AKA Challenge response has been sent 215 * updated to use IEEE 802.11w/D2.0 for management frame protection 216 (still experimental) 217 * fixed EAP-TTLS implementation not to crash on use of freed memory 218 if TLS library initialization fails 219 * added support for EAP-TNC (Trusted Network Connect) 220 (this version implements the EAP-TNC method and EAP-TTLS changes 221 needed to run two methods in sequence (IF-T) and the IF-IMC and 222 IF-TNCCS interfaces from TNCC) 223 2242006-11-24 - v0.5.6 225 * added experimental, integrated TLSv1 client implementation with the 226 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by 227 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in 228 .config); this can be useful, e.g., if the target system does not 229 have a suitable TLS library and a minimal code size is required 230 (total size of this internal TLS/crypto code is bit under 50 kB on 231 x86 and the crypto code is shared by rest of the supplicant so some 232 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB) 233 * removed STAKey handshake since PeerKey handshake has replaced it in 234 IEEE 802.11ma and there are no known deployments of STAKey 235 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 236 draft (draft-ietf-emu-eap-gpsk-01.txt) 237 * added preliminary implementation of IEEE 802.11w/D1.0 (management 238 frame protection) 239 (Note: this requires driver support to work properly.) 240 (Note2: IEEE 802.11w is an unapproved draft and subject to change.) 241 * fixed Windows named pipes ctrl_iface to not stop listening for 242 commands if client program opens a named pipe and closes it 243 immediately without sending a command 244 * fixed USIM PIN status determination for the case that PIN is not 245 needed (this allows EAP-AKA to be used with USIM cards that do not 246 use PIN) 247 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to 248 be used with cards that do not support file selection based on 249 partial AID 250 * added support for matching the subjectAltName of the authentication 251 server certificate against multiple name components (e.g., 252 altsubject_match="DNS:server.example.com;DNS:server2.example.com") 253 * fixed EAP-SIM/AKA key derivation for re-authentication case (only 254 affects IEEE 802.1X with dynamic WEP keys) 255 * changed ctrl_iface network configuration 'get' operations to not 256 return password/key material; if these fields are requested, "*" 257 will be returned if the password/key is set, but the value of the 258 parameter is not exposed 259 2602006-08-27 - v0.5.5 261 * added support for building Windows version with UNICODE defined 262 (wide-char functions) 263 * driver_ndis: fixed static WEP configuration to avoid race condition 264 issues with some NDIS drivers between association and setting WEP 265 keys 266 * driver_ndis: added validation for IELength value in scan results to 267 avoid crashes when using buggy NDIS drivers [Bug 165] 268 * fixed Release|Win32 target in the Visual Studio project files 269 (previously, only Debug|Win32 target was set properly) 270 * changed control interface API call wpa_ctrl_pending() to allow it to 271 return -1 on error (e.g., connection lost); control interface clients 272 will need to make sure that they verify that the value is indeed >0 273 when determining whether there are pending messages 274 * added an alternative control interface backend for Windows targets: 275 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default 276 control interface mechanism for Windows builds (previously, UDP to 277 localhost was used) 278 * changed ctrl_interface configuration for UNIX domain sockets: 279 - deprecated ctrl_interface_group variable (it may be removed in 280 future versions) 281 - allow both directory and group be configured with ctrl_interface 282 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel 283 - ctrl_interface=/var/run/wpa_supplicant is still supported for the 284 case when group is not changed 285 * added support for controlling more than one interface per process in 286 Windows version 287 * added a workaround for a case where the AP is using unknown address 288 (e.g., MAC address of the wired interface) as the source address for 289 EAPOL-Key frames; previously, that source address was used as the 290 destination for EAPOL-Key frames and in key derivation; now, BSSID is 291 used even if the source address does not match with it 292 (this resolves an interoperability issue with Thomson SpeedTouch 580) 293 * added a workaround for UDP-based control interface (which was used in 294 Windows builds before this release) to prevent packets with forged 295 addresses from being accepted as local control requests 296 * removed ndis_events.cpp and possibility of using external 297 ndis_events.exe; C version (ndis_events.c) is fully functional and 298 there is no desire to maintain two separate versions of this 299 implementation 300 * ndis_events: Changed NDIS event notification design to use WMI to 301 learn the adapter description through Win32_PnPEntity class; this 302 should fix some cases where the adapter name was not recognized 303 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500 304 USB) [Bug 113] 305 * fixed selection of the first network in ap_scan=2 mode; previously, 306 wpa_supplicant could get stuck in SCANNING state when only the first 307 network for enabled (e.g., after 'wpa_cli select_network 0') 308 * winsvc: added support for configuring ctrl_interface parameters in 309 registry (ctrl_interface string value in 310 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is 311 required to enable control interface (previously, this was hardcoded 312 to be enabled) 313 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4 314 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format 315 3162006-06-20 - v0.5.4 317 * fixed build with CONFIG_STAKEY=y [Bug 143] 318 * added support for doing MLME (IEEE 802.11 management frame 319 processing) in wpa_supplicant when using Devicescape IEEE 802.11 320 stack (wireless-dev.git tree) 321 * added a new network block configuration option, fragment_size, to 322 configure the maximum EAP fragment size 323 * driver_ndis: Disable WZC automatically for the selected interface to 324 avoid conflicts with two programs trying to control the radio; WZC 325 will be re-enabled (if it was enabled originally) when wpa_supplicant 326 is terminated 327 * added an experimental TLSv1 client implementation 328 (CONFIG_TLS=internal) that can be used instead of an external TLS 329 library, e.g., to reduce total size requirement on systems that do 330 not include any TLS library by default (this is not yet complete; 331 basic functionality is there, but certificate validation is not yet 332 included) 333 * added PeerKey handshake implementation for IEEE 802.11e 334 direct link setup (DLS) to replace STAKey handshake 335 * fixed WPA PSK update through ctrl_iface for the case where the old 336 PSK was derived from an ASCII passphrase and the new PSK is set as 337 a raw PSK (hex string) 338 * added new configuration option for identifying which network block 339 was used (id_str in wpa_supplicant.conf; included on 340 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental 341 variable in wpa_cli action scripts; in addition WPA_ID variable is 342 set to the current unique identifier that wpa_supplicant assigned 343 automatically for the network and that can be used with 344 GET_NETWORK/SET_NETWORK ctrl_iface commands) 345 * wpa_cli action script is now called only when the connect/disconnect 346 status changes or when associating with a different network 347 * fixed configuration parser not to remove CCMP from group cipher list 348 if WPA-None (adhoc) is used (pairwise=NONE in that case) 349 * fixed integrated NDIS events processing not to hang the process due 350 to a missed change in eloop_win.c API in v0.5.3 [Bug 155] 351 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK, 352 draft-clancy-emu-eap-shared-secret-00.txt) 353 * added Microsoft Visual Studio 2005 solution and project files for 354 build wpa_supplicant for Windows (see vs2005 subdirectory) 355 * eloop_win: fixed unregistration of Windows events 356 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet 357 at the end of RSN pre-authentication and added unregistration of 358 a Windows event to avoid getting eloop_win stuck with an invalid 359 handle 360 * driver_ndis: added support for selecting AP based on BSSID 361 * added new environmental variable for wpa_cli action scripts: 362 WPA_CTRL_DIR is the current control interface directory 363 * driver_ndis: added support for using NDISUIO instead of WinPcap for 364 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new 365 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build 366 wpa_supplicant without requiring WinPcap; note that using NDISUIO 367 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows 368 only one application to open the device 369 * changed NDIS driver naming to only include device GUID, e.g., 370 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap 371 specific \Device\NPF_ prefix before the GUID; the prefix is still 372 allowed for backwards compatibility, but it is not required anymore 373 when specifying the interface 374 * driver_ndis: re-initialize driver interface is the adapter is removed 375 and re-inserted [Bug 159] 376 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on 377 big endian hosts [Bug 146] 378 3792006-04-27 - v0.5.3 380 * fixed EAP-GTC response to include correct user identity when run as 381 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2) 382 * driver_ndis: Fixed encryption mode configuration for unencrypted 383 networks (some NDIS drivers ignored this, but others, e.g., Broadcom, 384 refused to associate with open networks) [Bug 106] 385 * driver_ndis: use BSSID OID polling to detect when IBSS network is 386 formed even when ndis_events code is included since some NDIS drivers 387 do not generate media connect events in IBSS mode 388 * config_winreg: allow global ctrl_interface parameter to be configured 389 in Windows registry 390 * config_winreg: added support for saving configuration data into 391 Windows registry 392 * added support for controlling network device operational state 393 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see 394 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client 395 that can use this information) 396 * driver_wext: added support for WE-21 change to SSID configuration 397 * driver_wext: fixed privacy configuration for static WEP keys mode 398 [Bug 140] 399 * added an optional driver_ops callback for MLME-SETPROTECTION.request 400 primitive 401 * added support for EAP-SAKE (no EAP method number allocated yet, so 402 this is using the same experimental type 255 as EAP-PSK) 403 * added support for dynamically loading EAP methods (.so files) instead 404 of requiring them to be statically linked in; this is disabled by 405 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information 406 on how to use this) 407 4082006-03-19 - v0.5.2 409 * do not try to use USIM APDUs when initializing PC/SC for SIM card 410 access for a network that has not enabled EAP-AKA 411 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in 412 v0.5.1 due to the new support for expanded EAP types) 413 * added support for generating EAP Expanded Nak 414 * try to fetch scan results once before requesting new scan when 415 starting up in ap_scan=1 mode (this can speed up initial association 416 a lot with, e.g., madwifi-ng driver) 417 * added support for receiving EAPOL frames from a Linux bridge 418 interface (-bbr0 on command line) 419 * fixed EAPOL re-authentication for sessions that used PMKSA caching 420 * changed EAP method registration to use a dynamic list of methods 421 instead of a static list generated at build time 422 * fixed PMKSA cache deinitialization not to use freed memory when 423 removing PMKSA entries 424 * fixed a memory leak in EAP-TTLS re-authentication 425 * reject WPA/WPA2 message 3/4 if it does not include any valid 426 WPA/RSN IE 427 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg 428 if the driver does not support SIOCSIWAUTH 429 4302006-01-29 - v0.5.1 431 * driver_test: added better support for multiple APs and STAs by using 432 a directory with sockets that include MAC address for each device in 433 the name (driver_param=test_dir=/tmp/test) 434 * added support for EAP expanded type (vendor specific EAP methods) 435 * added AP_SCAN command into ctrl_iface so that ap_scan configuration 436 option can be changed if needed 437 * wpa_cli/wpa_gui: skip non-socket files in control directory when 438 using UNIX domain sockets; this avoids selecting an incorrect 439 interface (e.g., a PID file could be in this directory, even though 440 use of this directory for something else than socket files is not 441 recommended) 442 * fixed TLS library deinitialization after RSN pre-authentication not 443 to disable TLS library for normal authentication 444 * driver_wext: Remove null-termination from SSID length if the driver 445 used it; some Linux drivers do this and they were causing problems in 446 wpa_supplicant not finding matching configuration block. This change 447 would break a case where the SSID actually ends in '\0', but that is 448 not likely to happen in real use. 449 * fixed PMKSA cache processing not to trigger deauthentication if the 450 current PMKSA cache entry is replaced with a valid new entry 451 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes 452 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or 453 ap_scan=2) 454 4552005-12-18 - v0.5.0 (beginning of 0.5.x development releases) 456 * added experimental STAKey handshake implementation for IEEE 802.11e 457 direct link setup (DLS); note: this is disabled by default in both 458 build and runtime configuration (can be enabled with CONFIG_STAKEY=y 459 and stakey=1) 460 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to 461 decrypt AT_ENCR_DATA attributes correctly 462 * fixed EAP-AKA to allow resynchronization within the same session 463 * made code closer to ANSI C89 standard to make it easier to port to 464 other C libraries and compilers 465 * started moving operating system or C library specific functions into 466 wrapper functions defined in os.h and implemented in os_*.c to make 467 code more portable 468 * wpa_supplicant can now be built with Microsoft Visual C++ 469 (e.g., with the freely available Toolkit 2003 version or Visual 470 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an 471 example makefile for nmake 472 * added support for using Windows registry for command line parameters 473 (CONFIG_MAIN=main_winsvc) and configuration data 474 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry 475 contents; this version can be run both as a Windows service and as a 476 normal application; 'wpasvc.exe app' to start as applicant, 477 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service, 478 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to 479 unregister a service 480 * made it possible to link ndis_events.exe functionality into 481 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED 482 * added better support for multiple control interface backends 483 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported 484 * fixed PC/SC code to use correct length for GSM AUTH command buffer 485 and to not use pioRecvPci with SCardTransmit() calls; these were not 486 causing visible problems with pcsc-lite, but Windows Winscard.dll 487 refused the previously used parameters; this fixes EAP-SIM and 488 EAP-AKA authentication using SIM/USIM card under Windows 489 * added new event loop implementation for Windows using 490 WaitForMultipleObject() instead of select() in order to allow waiting 491 for non-socket objects; this can be selected with 492 CONFIG_ELOOP=eloop_win in .config 493 * added support for selecting l2_packet implementation in .config 494 (CONFIG_L2_PACKET; following options are available now: linux, pcap, 495 winpcap, freebsd, none) 496 * added new l2_packet implementation for WinPcap 497 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to 498 reduce latency in EAPOL receive processing from about 100 ms to about 499 3 ms 500 * added support for EAP-FAST key derivation using other ciphers than 501 RC4-128-SHA for authentication and AES128-SHA for provisioning 502 * added support for configuring CA certificate as DER file and as a 503 configuration blob 504 * fixed private key configuration as configuration blob and added 505 support for using PKCS#12 as a blob 506 * tls_gnutls: added support for using PKCS#12 files; added support for 507 session resumption 508 * added support for loading trusted CA certificates from Windows 509 certificate store: ca_cert="cert_store://<name>", where <name> is 510 likely CA (Intermediate CA certificates) or ROOT (root certificates) 511 * added C version of ndis_events.cpp and made it possible to build this 512 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more 513 easily on cross-compilation builds 514 * added wpasvc.exe into Windows binary release; this is an alternative 515 version of wpa_supplicant.exe with configuration backend using 516 Windows registry and with the entry point designed to run as a 517 Windows service 518 * integrated ndis_events.exe functionality into wpa_supplicant.exe and 519 wpasvc.exe and removed this additional tool from the Windows binary 520 release since it is not needed anymore 521 * load winscard.dll functions dynamically when building with MinGW 522 since MinGW does not yet include winscard library 523 5242005-11-20 - v0.4.7 (beginning of 0.4.x stable releases) 525 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap 526 and WinPcap to receive frames sent to PAE group address 527 * disable EAP state machine when IEEE 802.1X authentication is not used 528 in order to get rid of bogus "EAP failed" messages 529 * fixed OpenSSL error reporting to go through all pending errors to 530 avoid confusing reports of old errors being reported at later point 531 during handshake 532 * fixed configuration file updating to not write empty variables 533 (e.g., proto or key_mgmt) that the file parser would not accept 534 * fixed ADD_NETWORK ctrl_iface command to use the same default values 535 for variables as empty network definitions read from config file 536 would get 537 * fixed EAP state machine to not discard EAP-Failure messages in many 538 cases (e.g., during TLS handshake) 539 * fixed a infinite loop in private key reading if the configured file 540 cannot be parsed successfully 541 * driver_madwifi: added support for madwifi-ng 542 * wpa_gui: do not display password/PSK field contents 543 * wpa_gui: added CA certificate configuration 544 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID 545 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if 546 the new AP is using different WPA/RSN IE 547 * use longer timeout for IEEE 802.11 association to avoid problems with 548 drivers that may take more than five second to associate 549 5502005-10-27 - v0.4.6 551 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in 552 RSN IE, but WPA IE would match with wpa_supplicant configuration 553 * added support for named configuration blobs in order to avoid having 554 to use file system for external files (e.g., certificates); 555 variables can be set to "blob://<blob name>" instead of file path to 556 use a named blob; supported fields: pac_file, client_cert, 557 private_key 558 * fixed RSN pre-authentication (it was broken in the clean up of WPA 559 state machine interface in v0.4.5) 560 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make 561 sure the driver configures broadcast decryption correctly 562 * added ca_path (and ca_path2) configuration variables that can be used 563 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the 564 system-wide trusted CA list 565 * added support for starting wpa_supplicant without a configuration 566 file (-C argument must be used to set ctrl_interface parameter for 567 this case; in addition, -p argument can be used to provide 568 driver_param; these new arguments can also be used with a 569 configuration to override the values from the configuration) 570 * added global control interface that can be optionally used for adding 571 and removing network interfaces dynamically (-g command line argument 572 for both wpa_supplicant and wpa_cli) without having to restart 573 wpa_supplicant process 574 * wpa_gui: 575 - try to save configuration whenever something is modified 576 - added WEP key configuration 577 - added possibility to edit the current network configuration 578 * driver_ndis: fixed driver polling not to increase frequency on each 579 received EAPOL frame due to incorrectly cancelled timeout 580 * added simple configuration file examples (in examples subdirectory) 581 * fixed driver_wext.c to filter wireless events based on ifindex to 582 avoid interfaces receiving events from other interfaces 583 * delay sending initial EAPOL-Start couple of seconds to speed up 584 authentication for the most common case of Authenticator starting 585 EAP authentication immediately after association 586 5872005-09-25 - v0.4.5 588 * added a workaround for clearing keys with ndiswrapper to allow 589 roaming from WPA enabled AP to plaintext one 590 * added docbook documentation (doc/docbook) that can be used to 591 generate, e.g., man pages 592 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for 593 PF_PACKET in order to prepare for network devices that do not use 594 Ethernet headers (e.g., network stack with native IEEE 802.11 frames) 595 * use receipt of EAPOL-Key frame as a lower layer success indication 596 for EAP state machine to allow recovery from dropped EAP-Success 597 frame 598 * cleaned up internal EAPOL frame processing by not including link 599 layer (Ethernet) header during WPA and EAPOL/EAP processing; this 600 header is added only when transmitted the frame; this makes it easier 601 to use wpa_supplicant on link layers that use different header than 602 Ethernet 603 * updated EAP-PSK to use draft 9 by default since this can now be 604 tested with hostapd; removed support for draft 3, including 605 server_nai configuration option from network blocks 606 * driver_wired: add PAE address to the multicast address list in order 607 to be able to receive EAPOL frames with drivers that do not include 608 these multicast addresses by default 609 * driver_wext: add support for WE-19 610 * added support for multiple configuration backends (CONFIG_BACKEND 611 option); currently, only 'file' is supported (i.e., the format used 612 in wpa_supplicant.conf) 613 * added support for updating configuration ('wpa_cli save_config'); 614 this is disabled by default and can be enabled with global 615 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli 616 and wpa_gui to store the configuration changes in a permanent store 617 * added GET_NETWORK ctrl_iface command 618 (e.g., 'wpa_cli get_network 0 ssid') 619 6202005-08-21 - v0.4.4 621 * replaced OpenSSL patch for EAP-FAST support 622 (openssl-tls-extensions.patch) with a more generic and correct 623 patch (the new patch is not compatible with the previous one, so the 624 OpenSSL library will need to be patched with the new patch in order 625 to be able to build wpa_supplicant with EAP-FAST support) 626 * added support for using Windows certificate store (through CryptoAPI) 627 for client certificate and private key operations (EAP-TLS) 628 (see wpa_supplicant.conf for more information on how to configure 629 this with private_key) 630 * ported wpa_gui to Windows 631 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be 632 built with the open source version of the Qt4 for Windows 633 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used 634 with drivers that do not support WPA 635 * ndis_events: fixed Windows 2000 support 636 * added support for enabling/disabling networks from the list of all 637 configured networks ('wpa_cli enable_network <network id>' and 638 'wpa_cli disable_network <network id>') 639 * added support for adding and removing network from the current 640 configuration ('wpa_cli add_network' and 'wpa_cli remove_network 641 <network id>'); added networks are disabled by default and they can 642 be enabled with enable_network command once the configuration is done 643 for the new network; note: configuration file is not yet updated, so 644 these new networks are lost when wpa_supplicant is restarted 645 * added support for setting network configuration parameters through 646 the control interface, for example: 647 wpa_cli set_network 0 ssid "\"my network\"" 648 * fixed parsing of strings that include both " and # within double 649 quoted area (e.g., "start"#end") 650 * added EAP workaround for PEAP session resumption: allow outer, 651 i.e., not tunneled, EAP-Success to terminate session since; this can 652 be disabled with eap_workaround=0 653 (this was allowed for PEAPv1 before, but now it is also allowed for 654 PEAPv0 since at least one RADIUS authentication server seems to be 655 doing this for PEAPv0, too) 656 * wpa_gui: added preliminary support for adding new networks to the 657 wpa_supplicant configuration (double click on the scan results to 658 open network configuration) 659 6602005-06-26 - v0.4.3 661 * removed interface for external EAPOL/EAP supplicant (e.g., 662 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required 663 anymore and is unlikely to be used by anyone 664 * driver_ndis: fixed WinPcap 3.0 support 665 * fixed build with CONFIG_DNET_PCAP=y on Linux 666 * l2_packet: moved different implementations into separate files 667 (l2_packet_*.c) 668 6692005-06-12 - v0.4.2 670 * driver_ipw: updated driver structures to match with ipw2200-1.0.4 671 (note: ipw2100-1.1.0 is likely to require an update to work with 672 this) 673 * added support for using ap_scan=2 mode with multiple network blocks; 674 wpa_supplicant will go through the networks one by one until the 675 driver reports a successful association; this uses the same order for 676 networks as scan_ssid=1 scans, i.e., the priority field is ignored 677 and the network block order in the file is used instead 678 * fixed a potential issue in RSN pre-authentication ending up using 679 freed memory if pre-authentication times out 680 * added support for matching alternative subject name extensions of the 681 authentication server certificate; new configuration variables 682 altsubject_match and altsubject_match2 683 * driver_ndis: added support for IEEE 802.1X authentication with wired 684 NDIS drivers 685 * added support for querying private key password (EAP-TLS) through the 686 control interface (wpa_cli/wpa_gui) if one is not included in the 687 configuration file 688 * driver_broadcom: fixed couple of memory leaks in scan result 689 processing 690 * EAP-PAX is now registered as EAP type 46 691 * fixed EAP-PAX MAC calculation 692 * fixed EAP-PAX CK and ICK key derivation 693 * added support for using password with EAP-PAX (as an alternative to 694 entering key with eappsk); SHA-1 hash of the password will be used as 695 the key in this case 696 * added support for arbitrary driver interface parameters through the 697 configuration file with a new driver_param field; this adds a new 698 driver_ops function set_param() 699 * added possibility to override l2_packet module with driver interface 700 API (new send_eapol handler); this can be used to implement driver 701 specific TX/RX functions for EAPOL frames 702 * fixed ctrl_interface_group processing for the case where gid is 703 entered as a number, not group name 704 * driver_test: added support for testing hostapd with wpa_supplicant 705 by using test driver interface without any kernel drivers or network 706 cards 707 7082005-05-22 - v0.4.1 709 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL 710 packets to be encrypted; this was apparently broken by the changed 711 ioctl order in v0.4.0 712 * driver_madwifi: added preliminary support for compiling against 'BSD' 713 branch of madwifi CVS tree 714 * added support for EAP-MSCHAPv2 password retries within the same EAP 715 authentication session 716 * added support for password changes with EAP-MSCHAPv2 (used when the 717 password has expired) 718 * added support for reading additional certificates from PKCS#12 files 719 and adding them to the certificate chain 720 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys 721 were used 722 * fixed a possible double free in EAP-TTLS fast-reauthentication when 723 identity or password is entered through control interface 724 * display EAP Notification messages to user through control interface 725 with "CTRL-EVENT-EAP-NOTIFICATION" prefix 726 * added GUI version of wpa_cli, wpa_gui; this is not build 727 automatically with 'make'; use 'make wpa_gui' to build (this requires 728 Qt development tools) 729 * added 'disconnect' command to control interface for setting 730 wpa_supplicant in state where it will not associate before 731 'reassociate' command has been used 732 * added support for selecting a network from the list of all configured 733 networks ('wpa_cli select_network <network id>'; this disabled all 734 other networks; to re-enable, 'wpa_cli select_network any') 735 * added support for getting scan results through control interface 736 * added EAP workaround for PEAPv1 session resumption: allow outer, 737 i.e., not tunneled, EAP-Success to terminate session since; this can 738 be disabled with eap_workaround=0 739 7402005-04-25 - v0.4.0 (beginning of 0.4.x development releases) 741 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be 742 used to reduce the size of the wpa_supplicant considerably if 743 debugging code is not needed 744 * fixed EAPOL-Key validation to drop packets with invalid Key Data 745 Length; such frames could have crashed wpa_supplicant due to buffer 746 overflow 747 * added support for wired authentication (IEEE 802.1X on wired 748 Ethernet); driver interface 'wired' 749 * obsoleted set_wpa() handler in the driver interface API (it can be 750 replaced by moving enable/disable functionality into init()/deinit()) 751 (calls to set_wpa() are still present for backwards compatibility, 752 but they may be removed in the future) 753 * driver_madwifi: fixed association in plaintext mode 754 * modified the EAP workaround that accepts EAP-Success with incorrect 755 Identifier to be even less strict about verification in order to 756 interoperate with some authentication servers 757 * added support for sending TLS alerts 758 * added support for 'any' SSID wildcard; if ssid is not configured or 759 is set to an empty string, any SSID will be accepted for non-WPA AP 760 * added support for asking PIN (for SIM) from frontends (e.g., 761 wpa_cli); if a PIN is needed, but not included in the configuration 762 file, a control interface request is sent and EAP processing is 763 delayed until the PIN is available 764 * added support for using external devices (e.g., a smartcard) for 765 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config); 766 new wpa_supplicant.conf variables: 767 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path 768 - network: engine, engine_id, key_id 769 * added experimental support for EAP-PAX 770 * added monitor mode for wpa_cli (-a<path to a program to run>) that 771 allows external commands (e.g., shell scripts) to be run based on 772 wpa_supplicant events, e.g., when authentication has been completed 773 and data connection is ready; other related wpa_cli arguments: 774 -B (run in background), -P (write PID file); wpa_supplicant has a new 775 command line argument (-W) that can be used to make it wait until a 776 control interface command is received in order to avoid missing 777 events 778 * added support for opportunistic WPA2 PMKSA key caching (disabled by 779 default, can be enabled with proactive_key_caching=1) 780 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where 781 Authenticator rejects PMKSA caching attempt and the driver is not 782 using assoc_info events 783 * added -P<pid file> argument for wpa_supplicant to write the current 784 process id into a file 785 7862005-02-12 - v0.3.7 (beginning of 0.3.x stable releases) 787 * added new phase1 option parameter, include_tls_length=1, to force 788 wpa_supplicant to add TLS Message Length field to all TLS messages 789 even if the packet is not fragmented; this may be needed with some 790 authentication servers 791 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when 792 using drivers that take care of AP selection (e.g., when using 793 ap_scan=2) 794 * fixed reprocessing of pending request after ctrl_iface requests for 795 identity/password/otp 796 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of 797 EAP-PEAP and EAP-TTLS 798 * all drivers using driver_wext: set interface up and select Managed 799 mode when starting wpa_supplicant; set interface down when exiting 800 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both 801 ipw2100 and ipw2200; please note that this also changed the 802 configuration variable in .config to CONFIG_DRIVER_IPW 803 8042005-01-24 - v0.3.6 805 * fixed a busy loop introduced in v0.3.5 for scan result processing 806 when no matching AP is found 807 8082005-01-23 - v0.3.5 809 * added a workaround for an interoperability issue with a Cisco AP 810 when using WPA2-PSK 811 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as 812 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow 813 retransmission of dropped frames) 814 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version 815 (e.g., segfault when processing EAPOL-Key frames) 816 * fixed EAP workaround and fast reauthentication configuration for 817 RSN pre-authentication; previously these were disabled and 818 pre-authentication would fail if the used authentication server 819 requires EAP workarounds 820 * added support for blacklisting APs that fail or timeout 821 authentication in ap_scan=1 mode so that all APs are tried in cases 822 where the ones with strongest signal level are failing authentication 823 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS 824 authentication attempt 825 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded 826 in the previous authentication (previously, only Phase 1 success was 827 verified) 828 8292005-01-09 - v0.3.4 830 * added preliminary support for IBSS (ad-hoc) mode configuration 831 (mode=1 in network block); this included a new key_mgmt mode 832 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no 833 key management; see wpa_supplicant.conf for more details and an 834 example on how to configure this (note: this is currently implemented 835 only for driver_hostapd.c, but the changes should be trivial to add 836 in associate() handler for other drivers, too (assuming the driver 837 supports WPA-None) 838 * added preliminary port for native Windows (i.e., no cygwin) using 839 mingw 840 8412005-01-02 - v0.3.3 842 * added optional support for GNU Readline and History Libraries for 843 wpa_cli (CONFIG_READLINE) 844 * cleaned up EAP state machine <-> method interface and number of 845 small problems with error case processing not terminating on 846 EAP-Failure but waiting for timeout 847 * added couple of workarounds for interoperability issues with a 848 Cisco AP when using WPA2 849 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt); 850 Note: This requires a patch for openssl to add support for TLS 851 extensions and number of workarounds for operations without 852 certificates. Proof of concept type of experimental patch is 853 included in openssl-tls-extensions.patch. 854 8552004-12-19 - v0.3.2 856 * fixed private key loading for cases where passphrase is not set 857 * fixed Windows/cygwin L2 packet handler freeing; previous version 858 could cause a segfault when RSN pre-authentication was completed 859 * added support for PMKSA caching with drivers that generate RSN IEs 860 (e.g., NDIS); currently, this is only implemented in driver_ndis.c, 861 but similar code can be easily added to driver_ndiswrapper.c once 862 ndiswrapper gets full support for RSN PMKSA caching 863 * improved recovery from PMKID mismatches by requesting full EAP 864 authentication in case of failed PMKSA caching attempt 865 * driver_ndis: added support for NDIS NdisMIncidateStatus() events 866 (this requires that ndis_events is ran while wpa_supplicant is 867 running) 868 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys 869 * added support for driver interfaces to replace the interface name 870 based on driver/OS specific mapping, e.g., in case of driver_ndis, 871 this allows the beginning of the adapter description to be used as 872 the interface name 873 * added support for CR+LF (Windows-style) line ends in configuration 874 file 875 * driver_ndis: enable radio before starting scanning, disable radio 876 when exiting 877 * modified association event handler to set portEnabled = FALSE before 878 clearing port Valid in order to reset EAP state machine and avoid 879 problems with new authentication getting ignored because of state 880 machines ending up in AUTHENTICATED/SUCCESS state based on old 881 information 882 * added support for driver events to add PMKID candidates in order to 883 allow drivers to give priority to most likely roaming candidates 884 * driver_hostap: moved PrivacyInvoked configuration to associate() 885 function so that this will not be set for plaintext connections 886 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver 887 interface can distinguish plaintext and IEEE 802.1X (no WPA) 888 authentication 889 * fixed static WEP key configuration to use broadcast/default type for 890 all keys (previously, the default TX key was configured as pairwise/ 891 unicast key) 892 * driver_ndis: added legacy WPA capability detection for non-WPA2 893 drivers 894 * added support for setting static WEP keys for IEEE 802.1X without 895 dynamic WEP keying (eapol_flags=0) 896 8972004-12-12 - v0.3.1 898 * added support for reading PKCS#12 (PFX) files (as a replacement for 899 PEM/DER) to get certificate and private key (CONFIG_PKCS12) 900 * fixed compilation with CONFIG_PCSC=y 901 * added new ap_scan mode, ap_scan=2, for drivers that take care of 902 association, but need to be configured with security policy and SSID, 903 e.g., ndiswrapper and NDIS driver; this mode should allow such 904 drivers to work with hidden SSIDs and optimized roaming; when 905 ap_scan=2 is used, only the first network block in the configuration 906 file is used and this configuration should have explicit security 907 policy (i.e., only one option in the lists) for key_mgmt, pairwise, 908 group, proto variables 909 * added experimental port of wpa_supplicant for Windows 910 - driver_ndis.c driver interface (NDIS OIDs) 911 - currently, this requires cygwin and WinPcap 912 - small utility, win_if_list, can be used to get interface name 913 * control interface can now be removed at build time; add 914 CONFIG_CTRL_IFACE=y to .config to maintain old functionality 915 * optional Xsupplicant interface can now be removed at build time; 916 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back) 917 * added auth_alg to driver interface associate() parameters to make it 918 easier for drivers to configure authentication algorithm as part of 919 the association 920 9212004-12-05 - v0.3.0 (beginning of 0.3.x development releases) 922 * driver_broadcom: added new driver interface for Broadcom wl.o driver 923 (a generic driver for Broadcom IEEE 802.11a/g cards) 924 * wpa_cli: fixed parsing of -p <path> command line argument 925 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS 926 ACK, not tunneled EAP-Success (of which only the first byte was 927 actually send due to a bug in previous code); this seems to 928 interoperate with most RADIUS servers that implements PEAPv1 929 * PEAPv1: added support for terminating PEAP authentication on tunneled 930 EAP-Success message; this can be configured by adding 931 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf 932 (some RADIUS servers require this whereas others require a tunneled 933 reply 934 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to 935 the old label for key derivation; previously, the default was 1, 936 but it looks like most existing PEAPv1 implementations use the old 937 label which is thus more suitable default option 938 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt) 939 * fixed parsing of wep_tx_keyidx 940 * added support for configuring list of allowed Phase 2 EAP types 941 (for both EAP-PEAP and EAP-TTLS) instead of only one type 942 * added support for configuring IEEE 802.11 authentication algorithm 943 (auth_alg; mainly for using Shared Key authentication with static 944 WEP keys) 945 * added support for EAP-AKA (with UMTS SIM) 946 * fixed couple of errors in PCSC handling that could have caused 947 random-looking errors for EAP-SIM 948 * added support for EAP-SIM pseudonyms and fast re-authentication 949 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS 950 session resumption) 951 * added support for EAP-SIM with two challanges 952 (phase1="sim_min_num_chal=3" can be used to require three challenges) 953 * added support for configuring DH/DSA parameters for an ephemeral DH 954 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters 955 dh_file and dh_file2 (phase 2); this adds support for using DSA keys 956 and optional DH key exchange to achieve forward secracy with RSA keys 957 * added support for matching subject of the authentication server 958 certificate with a substring when using EAP-TLS/PEAP/TTLS; new 959 configuration variables subject_match and subject_match2 960 * changed SSID configuration in driver_wext.c (used by many driver 961 interfaces) to use ssid_len+1 as the length for SSID since some Linux 962 drivers expect this 963 * fixed couple of unaligned reads in scan result parsing to fix WPA 964 connection on some platforms (e.g., ARM) 965 * added driver interface for Intel ipw2100 driver 966 * added support for LEAP with WPA 967 * added support for larger scan results report (old limit was 4 kB of 968 data, i.e., about 35 or so APs) when using Linux wireless extensions 969 v17 or newer 970 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start 971 only if there is a PMKSA cache entry for the current AP 972 * fixed error handling for case where reading of scan results fails: 973 must schedule a new scan or wpa_supplicant will remain waiting 974 forever 975 * changed debug output to remove shared password/key material by 976 default; all key information can be included with -K command line 977 argument to match the previous behavior 978 * added support for timestamping debug log messages (disabled by 979 default, can be enabled with -t command line argument) 980 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104 981 if keys are not configured to be used; this fixes IEEE 802.1X mode 982 with drivers that use this information to configure whether Privacy 983 bit can be in Beacon frames (e.g., ndiswrapper) 984 * avoid clearing driver keys if no keys have been configured since last 985 key clear request; this seems to improve reliability of group key 986 handshake for ndiswrapper & NDIS driver which seems to be suffering 987 of some kind of timing issue when the keys are cleared again after 988 association 989 * changed driver interface API: 990 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which 991 version is being used (now, this is set to 2; previously, it was 992 not defined) 993 - pass pointer to private data structure to all calls 994 - the new API is not backwards compatible; all in-tree driver 995 interfaces has been converted to the new API 996 * added support for controlling multiple interfaces (radios) per 997 wpa_supplicant process; each interface needs to be listed on the 998 command line (-c, -i, -D arguments) with -N as a separator 999 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi) 1000 * added a workaround for EAP servers that incorrectly use same Id for 1001 sequential EAP packets 1002 * changed libpcap/libdnet configuration to use .config variable, 1003 CONFIG_DNET_PCAP, instead of requiring Makefile modification 1004 * improved downgrade attack detection in IE verification of msg 3/4: 1005 verify both WPA and RSN IEs, if present, not only the selected one; 1006 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or 1007 Probe Response frame, and RSN is enabled in wpa_supplicant 1008 configuration 1009 * fixed WPA msg 3/4 processing to allow Key Data field contain other 1010 IEs than just one WPA IE 1011 * added support for FreeBSD and driver interface for the BSD net80211 1012 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the 1013 required kernel mods have not yet been committed 1014 * made EAP workarounds configurable; enabled by default, can be 1015 disabled with network block option eap_workaround=0 1016 10172004-07-17 - v0.2.4 (beginning of 0.2.x stable releases) 1018 * resolved couple of interoperability issues with EAP-PEAPv1 and 1019 Phase 2 (inner EAP) fragment reassembly 1020 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the 1021 AP is using non-zero key index for the unicast key and key index zero 1022 for the broadcast key 1023 * driver_hostap: fixed IEEE 802.1X WEP key updates and 1024 re-authentication by allowing unencrypted EAPOL frames when not using 1025 WPA 1026 * added a new driver interface, 'wext', which uses only standard, 1027 driver independent functionality in Linux wireless extensions; 1028 currently, this can be used only for non-WPA IEEE 802.1X mode, but 1029 eventually, this is to be extended to support full WPA/WPA2 once 1030 Linux wireless extensions get support for this 1031 * added support for mode in which the driver is responsible for AP 1032 scanning and selection; this is disabled by default and can be 1033 enabled with global ap_scan=0 variable in wpa_supplicant.conf; 1034 this mode can be used, e.g., with generic 'wext' driver interface to 1035 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver 1036 supporting wireless extensions. 1037 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g., 1038 operation with an AP that does not include SSID in the Beacon frames) 1039 * added support for new EAP authentication methods: 1040 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP 1041 * added support for asking one-time-passwords from frontends (e.g., 1042 wpa_cli); this 'otp' command works otherwise like 'password' command, 1043 but the password is used only once and the frontend will be asked for 1044 a new password whenever a request from authenticator requires a 1045 password; this can be used with both EAP-OTP and EAP-GTC 1046 * changed wpa_cli to automatically re-establish connection so that it 1047 does not need to be re-started when wpa_supplicant is terminated and 1048 started again 1049 * improved user data (identity/password/otp) requests through 1050 frontends: process pending EAPOL packets after getting new 1051 information so that full authentication does not need to be 1052 restarted; in addition, send pending requests again whenever a new 1053 frontend is attached 1054 * changed control frontends to use a new directory for socket files to 1055 make it easier for wpa_cli to automatically select between interfaces 1056 and to provide access control for the control interface; 1057 wpa_supplicant.conf: ctrl_interface is now a path 1058 (/var/run/wpa_supplicant is the recommended path) and 1059 ctrl_interface_group can be used to select which group gets access to 1060 the control interface; 1061 wpa_cli: by default, try to connect to the first interface available 1062 in /var/run/wpa_supplicant; this path can be overriden with -p option 1063 and an interface can be selected with -i option (i.e., in most common 1064 cases, wpa_cli does not need to get any arguments) 1065 * added support for LEAP 1066 * added driver interface for Linux ndiswrapper 1067 * added priority option for network blocks in the configuration file; 1068 this allows networks to be grouped based on priority (the scan 1069 results are searched for matches with network blocks in this order) 1070 10712004-06-20 - v0.2.3 1072 * sort scan results to improve AP selection 1073 * fixed control interface socket removal for some error cases 1074 * improved scan requesting and authentication timeout 1075 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and 1076 TLS processing 1077 * PEAP version can now be forced with phase1="peapver=<ver>" 1078 (mostly for testing; by default, the highest version supported by 1079 both the Supplicant and Authentication Server is selected 1080 automatically) 1081 * added support for madwifi driver (Atheros ar521x) 1082 * added a workaround for cases where AP sets Install Tx/Rx bit for 1083 WPA Group Key messages when pairwise keys are used (without this, 1084 the Group Key would be used for Tx and the AP would drop frames 1085 from the station) 1086 * added GSM SIM/USIM interface for GSM authentication algorithm for 1087 EAP-SIM; this requires pcsc-lite 1088 * added support for ATMEL AT76C5XXx driver 1089 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator 1090 does not include key data in the EAPOL-Key frame (i.e., part of 1091 EAP keying material is used as data encryption key) 1092 * added support for using plaintext and static WEP networks 1093 (key_mgmt=NONE) 1094 10952004-05-31 - v0.2.2 1096 * added support for new EAP authentication methods: 1097 EAP-TTLS/EAP-MD5-Challenge 1098 EAP-TTLS/EAP-GTC 1099 EAP-TTLS/EAP-MSCHAPv2 1100 EAP-TTLS/EAP-TLS 1101 EAP-TTLS/MSCHAPv2 1102 EAP-TTLS/MSCHAP 1103 EAP-TTLS/PAP 1104 EAP-TTLS/CHAP 1105 EAP-PEAP/TLS 1106 EAP-PEAP/GTC 1107 EAP-PEAP/MD5-Challenge 1108 EAP-GTC 1109 EAP-SIM (not yet complete; needs GSM/SIM authentication interface) 1110 * added support for anonymous identity (to be used when identity is 1111 sent in plaintext; real identity will be used within TLS protected 1112 tunnel (e.g., with EAP-TTLS) 1113 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli 1114 * added support for requesting identity and password information using 1115 control interface; in other words, the password for EAP-PEAP or 1116 EAP-TTLS does not need to be included in the configuration file since 1117 a frontand (e.g., wpa_cli) can ask it from the user 1118 * improved RSN pre-authentication to use a candidate list and process 1119 all candidates from each scan; not only one per scan 1120 * fixed RSN IE and WPA IE capabilities field parsing 1121 * ignore Tx bit in GTK IE when Pairwise keys are used 1122 * avoid making new scan requests during IEEE 802.1X negotiation 1123 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant 1124 with TLS support (this replaces the included implementation with 1125 library code to save about 8 kB since the library code is needed 1126 anyway for TLS) 1127 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support 1128 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config) 1129 11302004-05-06 - v0.2.1 1131 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1) 1132 Supplicant 1133 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1] 1134 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf] 1135 - EAP-MD5 (cannot be used with WPA-RADIUS) 1136 [draft-ietf-eap-rfc2284bis-09.txt] 1137 - EAP-TLS [RFC 2716] 1138 - EAP-MSCHAPv2 (currently used only with EAP-PEAP) 1139 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt] 1140 [draft-kamath-pppext-eap-mschapv2-00.txt] 1141 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by 1142 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey) 1143 - new configuration file options: eap, identity, password, ca_cert, 1144 client_cert, privatekey, private_key_passwd 1145 - Xsupplicant is not required anymore, but it can be used by 1146 disabling the internal IEEE 802.1X Supplicant with -e command line 1147 option 1148 - this code is not included in the default build; Makefile need to 1149 be edited for this (uncomment lines for selected functionality) 1150 - EAP-TLS and EAP-PEAP require openssl libraries 1151 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..) 1152 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys 1153 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X 1154 EAPOL-Key frames instead of WPA key handshakes) 1155 * added support for IEEE 802.11i/RSN (WPA2) 1156 - improved PTK Key Handshake 1157 - PMKSA caching, pre-authentication 1158 * fixed wpa_supplicant to ignore possible extra data after WPA 1159 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using 1160 TPTK' error from message 3 of 4-Way Handshake in case the AP 1161 includes extra data after the EAPOL-Key) 1162 * added interface for external programs (frontends) to control 1163 wpa_supplicant 1164 - CLI example (wpa_cli) with interactive mode and command line 1165 mode 1166 - replaced SIGUSR1 status/statistics with the new control interface 1167 * made some feature compile time configurable 1168 - .config file for make 1169 - driver interfaces (hostap, hermes, ..) 1170 - EAPOL/EAP functions 1171 11722004-02-15 - v0.2.0 1173 * Initial version of wpa_supplicant 1174
