1ChangeLog for wpa_supplicant 2 32008-11-28 - v0.5.11 4 * fixed race condition between disassociation event and group key 5 handshake to avoid getting stuck in incorrect state [Bug 261] 6 * updated D-Bus usage to avoid deprecated functions 7 * silence SIOCSIWAUTH ioctl failure message (these can be ignored in 8 most cases and are now only shown in debug output) 9 * increase timeout for IBSS connection 10 * driver_wext: do not overwrite BSS frequency if channel was already 11 received 12 * driver_wext: set interface down for mode switches, if needed (e.g., 13 for mac80211) 14 * driver_wext: fixed re-initialization of a removed and re-inserted 15 interface (e.g., USB dongle or on resume if driver was unloaded for 16 suspend) 17 * improve per-SSID scanning for drivers that report background scan 18 results frequently 19 * fixed scanning behavior after a failed initial association 20 * driver_wext: fixed processing of invalid event messages from kernel 21 not to crash wpa_supplicant (this could happen when using 64-bit 22 kernel with 32-bit userspace) 23 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits, 24 not bytes 25 * fixed canceling of PMKSA caching when using drivers that generate 26 RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know 27 about 28 292008-02-19 - v0.5.10 30 * added support for Makefile builds to include debug-log-to-a-file 31 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line) 32 * added network configuration parameter 'frequency' for setting 33 initial channel for IBSS (adhoc) networks 34 * fixed EAP-SIM and EAP-AKA message parser to validate attribute 35 lengths properly to avoid potential crash caused by invalid messages 36 * added driver_wext workaround for race condition between scanning and 37 association with drivers that take very long time to scan all 38 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now 39 using a longer hardcoded timeout for the scan if the driver supports 40 notifications for scan completion (SIOCGIWSCAN event); this helps, 41 e.g., in cases where wpa_supplicant and madwifi driver ended up in 42 loop where the driver did not even try to associate 43 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION 44 attributes in EAP-SIM Start/Response when using fast reauthentication 45 * fixed problems in getting NDIS events from WMI on Windows 2000 46 472007-12-02 - v0.5.9 48 * fixed an integer overflow issue in the ASN.1 parser used by the 49 (experimental) internal TLS implementation to avoid a potential 50 buffer read overflow 51 * fixed a race condition with -W option (wait for a control interface 52 monitor before starting) that could have caused the first messages to 53 be lost 54 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 55 draft (draft-ietf-emu-eap-gpsk-07.txt) 56 * added ctrl_iface RECONNECT (wpa_cli reconnect) command 57 (like reassociate, but only takes effect if already associated) 58 * fixed a possible race condition between wpa_cli reassociate and 59 wpa_cli disconnect 60 * return a non-zero exit code from non-interactive wpa_cli if the 61 command is not recognized or fails 62 * fixed 0.5.8 regressions in BSS selection that prevented wildcard SSID 63 from being used with non-WPA networks and disabled workaround for 64 ignoring bogus WPA/RSN IE in non-WPA configuration 65 * fixed OpenSSL TLS wrapper to clear trusted CA list to allow 66 network blocks to use different trusted CA configurations 67 * fixed a potential EAP state machine loop when mloving from PSK to EAP 68 configuration without restarting wpa_supplicant 69 702007-05-28 - v0.5.8 71 * updated driver_wext.c to build with the current wireless-dev.git tree 72 and net/d80211 changes 73 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 74 draft (draft-ietf-emu-eap-gpsk-03.txt) 75 * fixed 'make install' 76 * fixed EAP-TTLS implementation not to crash on use of freed memory 77 if TLS library initialization fails 78 * fixed EAP-AKA Notification processing to allow Notification to be 79 processed after AKA Challenge response has been sent 80 812006-12-31 - v0.5.7 82 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48 83 * updated EAP-PSK to use the IANA-allocated EAP type 47 84 * fixed EAP-PAX key derivation 85 * fixed EAP-PSK bit ordering of the Flags field 86 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in 87 tunnelled identity request (previously, the identifier from the outer 88 method was used, not the tunnelled identifier which could be 89 different) 90 * fixed EAP-TTLS AVP parser processing for too short AVP lengths 91 * added support for EAP-FAST authentication with inner methods that 92 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported 93 for PAC provisioning) 94 * fixed dbus ctrl_iface to validate message interface before 95 dispatching to avoid a possible segfault [Bug 190] 96 * fixed PeerKey key derivation to use the correct PRF label 97 * updated Windows binary build to link against OpenSSL 0.9.8d and 98 added support for EAP-FAST 99 1002006-11-24 - v0.5.6 101 * added experimental, integrated TLSv1 client implementation with the 102 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by 103 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in 104 .config); this can be useful, e.g., if the target system does not 105 have a suitable TLS library and a minimal code size is required 106 (total size of this internal TLS/crypto code is bit under 50 kB on 107 x86 and the crypto code is shared by rest of the supplicant so some 108 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB) 109 * removed STAKey handshake since PeerKey handshake has replaced it in 110 IEEE 802.11ma and there are no known deployments of STAKey 111 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest 112 draft (draft-ietf-emu-eap-gpsk-01.txt) 113 * added preliminary implementation of IEEE 802.11w/D1.0 (management 114 frame protection) 115 (Note: this requires driver support to work properly.) 116 (Note2: IEEE 802.11w is an unapproved draft and subject to change.) 117 * fixed Windows named pipes ctrl_iface to not stop listening for 118 commands if client program opens a named pipe and closes it 119 immediately without sending a command 120 * fixed USIM PIN status determination for the case that PIN is not 121 needed (this allows EAP-AKA to be used with USIM cards that do not 122 use PIN) 123 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to 124 be used with cards that do not support file selection based on 125 partial AID 126 * added support for matching the subjectAltName of the authentication 127 server certificate against multiple name components (e.g., 128 altsubject_match="DNS:server.example.com;DNS:server2.example.com") 129 * fixed EAP-SIM/AKA key derivation for re-authentication case (only 130 affects IEEE 802.1X with dynamic WEP keys) 131 * changed ctrl_iface network configuration 'get' operations to not 132 return password/key material; if these fields are requested, "*" 133 will be returned if the password/key is set, but the value of the 134 parameter is not exposed 135 1362006-08-27 - v0.5.5 137 * added support for building Windows version with UNICODE defined 138 (wide-char functions) 139 * driver_ndis: fixed static WEP configuration to avoid race condition 140 issues with some NDIS drivers between association and setting WEP 141 keys 142 * driver_ndis: added validation for IELength value in scan results to 143 avoid crashes when using buggy NDIS drivers [Bug 165] 144 * fixed Release|Win32 target in the Visual Studio project files 145 (previously, only Debug|Win32 target was set properly) 146 * changed control interface API call wpa_ctrl_pending() to allow it to 147 return -1 on error (e.g., connection lost); control interface clients 148 will need to make sure that they verify that the value is indeed >0 149 when determining whether there are pending messages 150 * added an alternative control interface backend for Windows targets: 151 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default 152 control interface mechanism for Windows builds (previously, UDP to 153 localhost was used) 154 * changed ctrl_interface configuration for UNIX domain sockets: 155 - deprecated ctrl_interface_group variable (it may be removed in 156 future versions) 157 - allow both directory and group be configured with ctrl_interface 158 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel 159 - ctrl_interface=/var/run/wpa_supplicant is still supported for the 160 case when group is not changed 161 * added support for controlling more than one interface per process in 162 Windows version 163 * added a workaround for a case where the AP is using unknown address 164 (e.g., MAC address of the wired interface) as the source address for 165 EAPOL-Key frames; previously, that source address was used as the 166 destination for EAPOL-Key frames and in key derivation; now, BSSID is 167 used even if the source address does not match with it 168 (this resolves an interoperability issue with Thomson SpeedTouch 580) 169 * added a workaround for UDP-based control interface (which was used in 170 Windows builds before this release) to prevent packets with forged 171 addresses from being accepted as local control requests 172 * removed ndis_events.cpp and possibility of using external 173 ndis_events.exe; C version (ndis_events.c) is fully functional and 174 there is no desire to maintain two separate versions of this 175 implementation 176 * ndis_events: Changed NDIS event notification design to use WMI to 177 learn the adapter description through Win32_PnPEntity class; this 178 should fix some cases where the adapter name was not recognized 179 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500 180 USB) [Bug 113] 181 * fixed selection of the first network in ap_scan=2 mode; previously, 182 wpa_supplicant could get stuck in SCANNING state when only the first 183 network for enabled (e.g., after 'wpa_cli select_network 0') 184 * winsvc: added support for configuring ctrl_interface parameters in 185 registry (ctrl_interface string value in 186 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is 187 required to enable control interface (previously, this was hardcoded 188 to be enabled) 189 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4 190 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format 191 1922006-06-20 - v0.5.4 193 * fixed build with CONFIG_STAKEY=y [Bug 143] 194 * added support for doing MLME (IEEE 802.11 management frame 195 processing) in wpa_supplicant when using Devicescape IEEE 802.11 196 stack (wireless-dev.git tree) 197 * added a new network block configuration option, fragment_size, to 198 configure the maximum EAP fragment size 199 * driver_ndis: Disable WZC automatically for the selected interface to 200 avoid conflicts with two programs trying to control the radio; WZC 201 will be re-enabled (if it was enabled originally) when wpa_supplicant 202 is terminated 203 * added an experimental TLSv1 client implementation 204 (CONFIG_TLS=internal) that can be used instead of an external TLS 205 library, e.g., to reduce total size requirement on systems that do 206 not include any TLS library by default (this is not yet complete; 207 basic functionality is there, but certificate validation is not yet 208 included) 209 * added PeerKey handshake implementation for IEEE 802.11e 210 direct link setup (DLS) to replace STAKey handshake 211 * fixed WPA PSK update through ctrl_iface for the case where the old 212 PSK was derived from an ASCII passphrase and the new PSK is set as 213 a raw PSK (hex string) 214 * added new configuration option for identifying which network block 215 was used (id_str in wpa_supplicant.conf; included on 216 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental 217 variable in wpa_cli action scripts; in addition WPA_ID variable is 218 set to the current unique identifier that wpa_supplicant assigned 219 automatically for the network and that can be used with 220 GET_NETWORK/SET_NETWORK ctrl_iface commands) 221 * wpa_cli action script is now called only when the connect/disconnect 222 status changes or when associating with a different network 223 * fixed configuration parser not to remove CCMP from group cipher list 224 if WPA-None (adhoc) is used (pairwise=NONE in that case) 225 * fixed integrated NDIS events processing not to hang the process due 226 to a missed change in eloop_win.c API in v0.5.3 [Bug 155] 227 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK, 228 draft-clancy-emu-eap-shared-secret-00.txt) 229 * added Microsoft Visual Studio 2005 solution and project files for 230 build wpa_supplicant for Windows (see vs2005 subdirectory) 231 * eloop_win: fixed unregistration of Windows events 232 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet 233 at the end of RSN pre-authentication and added unregistration of 234 a Windows event to avoid getting eloop_win stuck with an invalid 235 handle 236 * driver_ndis: added support for selecting AP based on BSSID 237 * added new environmental variable for wpa_cli action scripts: 238 WPA_CTRL_DIR is the current control interface directory 239 * driver_ndis: added support for using NDISUIO instead of WinPcap for 240 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new 241 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build 242 wpa_supplicant without requiring WinPcap; note that using NDISUIO 243 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows 244 only one application to open the device 245 * changed NDIS driver naming to only include device GUID, e.g., 246 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap 247 specific \Device\NPF_ prefix before the GUID; the prefix is still 248 allowed for backwards compatibility, but it is not required anymore 249 when specifying the interface 250 * driver_ndis: re-initialize driver interface is the adapter is removed 251 and re-inserted [Bug 159] 252 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on 253 big endian hosts [Bug 146] 254 2552006-04-27 - v0.5.3 256 * fixed EAP-GTC response to include correct user identity when run as 257 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2) 258 * driver_ndis: Fixed encryption mode configuration for unencrypted 259 networks (some NDIS drivers ignored this, but others, e.g., Broadcom, 260 refused to associate with open networks) [Bug 106] 261 * driver_ndis: use BSSID OID polling to detect when IBSS network is 262 formed even when ndis_events code is included since some NDIS drivers 263 do not generate media connect events in IBSS mode 264 * config_winreg: allow global ctrl_interface parameter to be configured 265 in Windows registry 266 * config_winreg: added support for saving configuration data into 267 Windows registry 268 * added support for controlling network device operational state 269 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see 270 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client 271 that can use this information) 272 * driver_wext: added support for WE-21 change to SSID configuration 273 * driver_wext: fixed privacy configuration for static WEP keys mode 274 [Bug 140] 275 * added an optional driver_ops callback for MLME-SETPROTECTION.request 276 primitive 277 * added support for EAP-SAKE (no EAP method number allocated yet, so 278 this is using the same experimental type 255 as EAP-PSK) 279 * added support for dynamically loading EAP methods (.so files) instead 280 of requiring them to be statically linked in; this is disabled by 281 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information 282 on how to use this) 283 2842006-03-19 - v0.5.2 285 * do not try to use USIM APDUs when initializing PC/SC for SIM card 286 access for a network that has not enabled EAP-AKA 287 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in 288 v0.5.1 due to the new support for expanded EAP types) 289 * added support for generating EAP Expanded Nak 290 * try to fetch scan results once before requesting new scan when 291 starting up in ap_scan=1 mode (this can speed up initial association 292 a lot with, e.g., madwifi-ng driver) 293 * added support for receiving EAPOL frames from a Linux bridge 294 interface (-bbr0 on command line) 295 * fixed EAPOL re-authentication for sessions that used PMKSA caching 296 * changed EAP method registration to use a dynamic list of methods 297 instead of a static list generated at build time 298 * fixed PMKSA cache deinitialization not to use freed memory when 299 removing PMKSA entries 300 * fixed a memory leak in EAP-TTLS re-authentication 301 * reject WPA/WPA2 message 3/4 if it does not include any valid 302 WPA/RSN IE 303 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg 304 if the driver does not support SIOCSIWAUTH 305 3062006-01-29 - v0.5.1 307 * driver_test: added better support for multiple APs and STAs by using 308 a directory with sockets that include MAC address for each device in 309 the name (driver_param=test_dir=/tmp/test) 310 * added support for EAP expanded type (vendor specific EAP methods) 311 * added AP_SCAN command into ctrl_iface so that ap_scan configuration 312 option can be changed if needed 313 * wpa_cli/wpa_gui: skip non-socket files in control directory when 314 using UNIX domain sockets; this avoids selecting an incorrect 315 interface (e.g., a PID file could be in this directory, even though 316 use of this directory for something else than socket files is not 317 recommended) 318 * fixed TLS library deinitialization after RSN pre-authentication not 319 to disable TLS library for normal authentication 320 * driver_wext: Remove null-termination from SSID length if the driver 321 used it; some Linux drivers do this and they were causing problems in 322 wpa_supplicant not finding matching configuration block. This change 323 would break a case where the SSID actually ends in '\0', but that is 324 not likely to happen in real use. 325 * fixed PMKSA cache processing not to trigger deauthentication if the 326 current PMKSA cache entry is replaced with a valid new entry 327 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes 328 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or 329 ap_scan=2) 330 3312005-12-18 - v0.5.0 (beginning of 0.5.x development releases) 332 * added experimental STAKey handshake implementation for IEEE 802.11e 333 direct link setup (DLS); note: this is disabled by default in both 334 build and runtime configuration (can be enabled with CONFIG_STAKEY=y 335 and stakey=1) 336 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to 337 decrypt AT_ENCR_DATA attributes correctly 338 * fixed EAP-AKA to allow resynchronization within the same session 339 * made code closer to ANSI C89 standard to make it easier to port to 340 other C libraries and compilers 341 * started moving operating system or C library specific functions into 342 wrapper functions defined in os.h and implemented in os_*.c to make 343 code more portable 344 * wpa_supplicant can now be built with Microsoft Visual C++ 345 (e.g., with the freely available Toolkit 2003 version or Visual 346 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an 347 example makefile for nmake 348 * added support for using Windows registry for command line parameters 349 (CONFIG_MAIN=main_winsvc) and configuration data 350 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry 351 contents; this version can be run both as a Windows service and as a 352 normal application; 'wpasvc.exe app' to start as applicant, 353 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service, 354 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to 355 unregister a service 356 * made it possible to link ndis_events.exe functionality into 357 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED 358 * added better support for multiple control interface backends 359 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported 360 * fixed PC/SC code to use correct length for GSM AUTH command buffer 361 and to not use pioRecvPci with SCardTransmit() calls; these were not 362 causing visible problems with pcsc-lite, but Windows Winscard.dll 363 refused the previously used parameters; this fixes EAP-SIM and 364 EAP-AKA authentication using SIM/USIM card under Windows 365 * added new event loop implementation for Windows using 366 WaitForMultipleObject() instead of select() in order to allow waiting 367 for non-socket objects; this can be selected with 368 CONFIG_ELOOP=eloop_win in .config 369 * added support for selecting l2_packet implementation in .config 370 (CONFIG_L2_PACKET; following options are available now: linux, pcap, 371 winpcap, freebsd, none) 372 * added new l2_packet implementation for WinPcap 373 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to 374 reduce latency in EAPOL receive processing from about 100 ms to about 375 3 ms 376 * added support for EAP-FAST key derivation using other ciphers than 377 RC4-128-SHA for authentication and AES128-SHA for provisioning 378 * added support for configuring CA certificate as DER file and as a 379 configuration blob 380 * fixed private key configuration as configuration blob and added 381 support for using PKCS#12 as a blob 382 * tls_gnutls: added support for using PKCS#12 files; added support for 383 session resumption 384 * added support for loading trusted CA certificates from Windows 385 certificate store: ca_cert="cert_store://<name>", where <name> is 386 likely CA (Intermediate CA certificates) or ROOT (root certificates) 387 * added C version of ndis_events.cpp and made it possible to build this 388 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more 389 easily on cross-compilation builds 390 * added wpasvc.exe into Windows binary release; this is an alternative 391 version of wpa_supplicant.exe with configuration backend using 392 Windows registry and with the entry point designed to run as a 393 Windows service 394 * integrated ndis_events.exe functionality into wpa_supplicant.exe and 395 wpasvc.exe and removed this additional tool from the Windows binary 396 release since it is not needed anymore 397 * load winscard.dll functions dynamically when building with MinGW 398 since MinGW does not yet include winscard library 399 4002005-11-20 - v0.4.7 (beginning of 0.4.x stable releases) 401 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap 402 and WinPcap to receive frames sent to PAE group address 403 * disable EAP state machine when IEEE 802.1X authentication is not used 404 in order to get rid of bogus "EAP failed" messages 405 * fixed OpenSSL error reporting to go through all pending errors to 406 avoid confusing reports of old errors being reported at later point 407 during handshake 408 * fixed configuration file updating to not write empty variables 409 (e.g., proto or key_mgmt) that the file parser would not accept 410 * fixed ADD_NETWORK ctrl_iface command to use the same default values 411 for variables as empty network definitions read from config file 412 would get 413 * fixed EAP state machine to not discard EAP-Failure messages in many 414 cases (e.g., during TLS handshake) 415 * fixed a infinite loop in private key reading if the configured file 416 cannot be parsed successfully 417 * driver_madwifi: added support for madwifi-ng 418 * wpa_gui: do not display password/PSK field contents 419 * wpa_gui: added CA certificate configuration 420 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID 421 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if 422 the new AP is using different WPA/RSN IE 423 * use longer timeout for IEEE 802.11 association to avoid problems with 424 drivers that may take more than five second to associate 425 4262005-10-27 - v0.4.6 427 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in 428 RSN IE, but WPA IE would match with wpa_supplicant configuration 429 * added support for named configuration blobs in order to avoid having 430 to use file system for external files (e.g., certificates); 431 variables can be set to "blob://<blob name>" instead of file path to 432 use a named blob; supported fields: pac_file, client_cert, 433 private_key 434 * fixed RSN pre-authentication (it was broken in the clean up of WPA 435 state machine interface in v0.4.5) 436 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make 437 sure the driver configures broadcast decryption correctly 438 * added ca_path (and ca_path2) configuration variables that can be used 439 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the 440 system-wide trusted CA list 441 * added support for starting wpa_supplicant without a configuration 442 file (-C argument must be used to set ctrl_interface parameter for 443 this case; in addition, -p argument can be used to provide 444 driver_param; these new arguments can also be used with a 445 configuration to override the values from the configuration) 446 * added global control interface that can be optionally used for adding 447 and removing network interfaces dynamically (-g command line argument 448 for both wpa_supplicant and wpa_cli) without having to restart 449 wpa_supplicant process 450 * wpa_gui: 451 - try to save configuration whenever something is modified 452 - added WEP key configuration 453 - added possibility to edit the current network configuration 454 * driver_ndis: fixed driver polling not to increase frequency on each 455 received EAPOL frame due to incorrectly cancelled timeout 456 * added simple configuration file examples (in examples subdirectory) 457 * fixed driver_wext.c to filter wireless events based on ifindex to 458 avoid interfaces receiving events from other interfaces 459 * delay sending initial EAPOL-Start couple of seconds to speed up 460 authentication for the most common case of Authenticator starting 461 EAP authentication immediately after association 462 4632005-09-25 - v0.4.5 464 * added a workaround for clearing keys with ndiswrapper to allow 465 roaming from WPA enabled AP to plaintext one 466 * added docbook documentation (doc/docbook) that can be used to 467 generate, e.g., man pages 468 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for 469 PF_PACKET in order to prepare for network devices that do not use 470 Ethernet headers (e.g., network stack with native IEEE 802.11 frames) 471 * use receipt of EAPOL-Key frame as a lower layer success indication 472 for EAP state machine to allow recovery from dropped EAP-Success 473 frame 474 * cleaned up internal EAPOL frame processing by not including link 475 layer (Ethernet) header during WPA and EAPOL/EAP processing; this 476 header is added only when transmitted the frame; this makes it easier 477 to use wpa_supplicant on link layers that use different header than 478 Ethernet 479 * updated EAP-PSK to use draft 9 by default since this can now be 480 tested with hostapd; removed support for draft 3, including 481 server_nai configuration option from network blocks 482 * driver_wired: add PAE address to the multicast address list in order 483 to be able to receive EAPOL frames with drivers that do not include 484 these multicast addresses by default 485 * driver_wext: add support for WE-19 486 * added support for multiple configuration backends (CONFIG_BACKEND 487 option); currently, only 'file' is supported (i.e., the format used 488 in wpa_supplicant.conf) 489 * added support for updating configuration ('wpa_cli save_config'); 490 this is disabled by default and can be enabled with global 491 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli 492 and wpa_gui to store the configuration changes in a permanent store 493 * added GET_NETWORK ctrl_iface command 494 (e.g., 'wpa_cli get_network 0 ssid') 495 4962005-08-21 - v0.4.4 497 * replaced OpenSSL patch for EAP-FAST support 498 (openssl-tls-extensions.patch) with a more generic and correct 499 patch (the new patch is not compatible with the previous one, so the 500 OpenSSL library will need to be patched with the new patch in order 501 to be able to build wpa_supplicant with EAP-FAST support) 502 * added support for using Windows certificate store (through CryptoAPI) 503 for client certificate and private key operations (EAP-TLS) 504 (see wpa_supplicant.conf for more information on how to configure 505 this with private_key) 506 * ported wpa_gui to Windows 507 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be 508 built with the open source version of the Qt4 for Windows 509 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used 510 with drivers that do not support WPA 511 * ndis_events: fixed Windows 2000 support 512 * added support for enabling/disabling networks from the list of all 513 configured networks ('wpa_cli enable_network <network id>' and 514 'wpa_cli disable_network <network id>') 515 * added support for adding and removing network from the current 516 configuration ('wpa_cli add_network' and 'wpa_cli remove_network 517 <network id>'); added networks are disabled by default and they can 518 be enabled with enable_network command once the configuration is done 519 for the new network; note: configuration file is not yet updated, so 520 these new networks are lost when wpa_supplicant is restarted 521 * added support for setting network configuration parameters through 522 the control interface, for example: 523 wpa_cli set_network 0 ssid "\"my network\"" 524 * fixed parsing of strings that include both " and # within double 525 quoted area (e.g., "start"#end") 526 * added EAP workaround for PEAP session resumption: allow outer, 527 i.e., not tunneled, EAP-Success to terminate session since; this can 528 be disabled with eap_workaround=0 529 (this was allowed for PEAPv1 before, but now it is also allowed for 530 PEAPv0 since at least one RADIUS authentication server seems to be 531 doing this for PEAPv0, too) 532 * wpa_gui: added preliminary support for adding new networks to the 533 wpa_supplicant configuration (double click on the scan results to 534 open network configuration) 535 5362005-06-26 - v0.4.3 537 * removed interface for external EAPOL/EAP supplicant (e.g., 538 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required 539 anymore and is unlikely to be used by anyone 540 * driver_ndis: fixed WinPcap 3.0 support 541 * fixed build with CONFIG_DNET_PCAP=y on Linux 542 * l2_packet: moved different implementations into separate files 543 (l2_packet_*.c) 544 5452005-06-12 - v0.4.2 546 * driver_ipw: updated driver structures to match with ipw2200-1.0.4 547 (note: ipw2100-1.1.0 is likely to require an update to work with 548 this) 549 * added support for using ap_scan=2 mode with multiple network blocks; 550 wpa_supplicant will go through the networks one by one until the 551 driver reports a successful association; this uses the same order for 552 networks as scan_ssid=1 scans, i.e., the priority field is ignored 553 and the network block order in the file is used instead 554 * fixed a potential issue in RSN pre-authentication ending up using 555 freed memory if pre-authentication times out 556 * added support for matching alternative subject name extensions of the 557 authentication server certificate; new configuration variables 558 altsubject_match and altsubject_match2 559 * driver_ndis: added support for IEEE 802.1X authentication with wired 560 NDIS drivers 561 * added support for querying private key password (EAP-TLS) through the 562 control interface (wpa_cli/wpa_gui) if one is not included in the 563 configuration file 564 * driver_broadcom: fixed couple of memory leaks in scan result 565 processing 566 * EAP-PAX is now registered as EAP type 46 567 * fixed EAP-PAX MAC calculation 568 * fixed EAP-PAX CK and ICK key derivation 569 * added support for using password with EAP-PAX (as an alternative to 570 entering key with eappsk); SHA-1 hash of the password will be used as 571 the key in this case 572 * added support for arbitrary driver interface parameters through the 573 configuration file with a new driver_param field; this adds a new 574 driver_ops function set_param() 575 * added possibility to override l2_packet module with driver interface 576 API (new send_eapol handler); this can be used to implement driver 577 specific TX/RX functions for EAPOL frames 578 * fixed ctrl_interface_group processing for the case where gid is 579 entered as a number, not group name 580 * driver_test: added support for testing hostapd with wpa_supplicant 581 by using test driver interface without any kernel drivers or network 582 cards 583 5842005-05-22 - v0.4.1 585 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL 586 packets to be encrypted; this was apparently broken by the changed 587 ioctl order in v0.4.0 588 * driver_madwifi: added preliminary support for compiling against 'BSD' 589 branch of madwifi CVS tree 590 * added support for EAP-MSCHAPv2 password retries within the same EAP 591 authentication session 592 * added support for password changes with EAP-MSCHAPv2 (used when the 593 password has expired) 594 * added support for reading additional certificates from PKCS#12 files 595 and adding them to the certificate chain 596 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys 597 were used 598 * fixed a possible double free in EAP-TTLS fast-reauthentication when 599 identity or password is entered through control interface 600 * display EAP Notification messages to user through control interface 601 with "CTRL-EVENT-EAP-NOTIFICATION" prefix 602 * added GUI version of wpa_cli, wpa_gui; this is not build 603 automatically with 'make'; use 'make wpa_gui' to build (this requires 604 Qt development tools) 605 * added 'disconnect' command to control interface for setting 606 wpa_supplicant in state where it will not associate before 607 'reassociate' command has been used 608 * added support for selecting a network from the list of all configured 609 networks ('wpa_cli select_network <network id>'; this disabled all 610 other networks; to re-enable, 'wpa_cli select_network any') 611 * added support for getting scan results through control interface 612 * added EAP workaround for PEAPv1 session resumption: allow outer, 613 i.e., not tunneled, EAP-Success to terminate session since; this can 614 be disabled with eap_workaround=0 615 6162005-04-25 - v0.4.0 (beginning of 0.4.x development releases) 617 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be 618 used to reduce the size of the wpa_supplicant considerably if 619 debugging code is not needed 620 * fixed EAPOL-Key validation to drop packets with invalid Key Data 621 Length; such frames could have crashed wpa_supplicant due to buffer 622 overflow 623 * added support for wired authentication (IEEE 802.1X on wired 624 Ethernet); driver interface 'wired' 625 * obsoleted set_wpa() handler in the driver interface API (it can be 626 replaced by moving enable/disable functionality into init()/deinit()) 627 (calls to set_wpa() are still present for backwards compatibility, 628 but they may be removed in the future) 629 * driver_madwifi: fixed association in plaintext mode 630 * modified the EAP workaround that accepts EAP-Success with incorrect 631 Identifier to be even less strict about verification in order to 632 interoperate with some authentication servers 633 * added support for sending TLS alerts 634 * added support for 'any' SSID wildcard; if ssid is not configured or 635 is set to an empty string, any SSID will be accepted for non-WPA AP 636 * added support for asking PIN (for SIM) from frontends (e.g., 637 wpa_cli); if a PIN is needed, but not included in the configuration 638 file, a control interface request is sent and EAP processing is 639 delayed until the PIN is available 640 * added support for using external devices (e.g., a smartcard) for 641 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config); 642 new wpa_supplicant.conf variables: 643 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path 644 - network: engine, engine_id, key_id 645 * added experimental support for EAP-PAX 646 * added monitor mode for wpa_cli (-a<path to a program to run>) that 647 allows external commands (e.g., shell scripts) to be run based on 648 wpa_supplicant events, e.g., when authentication has been completed 649 and data connection is ready; other related wpa_cli arguments: 650 -B (run in background), -P (write PID file); wpa_supplicant has a new 651 command line argument (-W) that can be used to make it wait until a 652 control interface command is received in order to avoid missing 653 events 654 * added support for opportunistic WPA2 PMKSA key caching (disabled by 655 default, can be enabled with proactive_key_caching=1) 656 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where 657 Authenticator rejects PMKSA caching attempt and the driver is not 658 using assoc_info events 659 * added -P<pid file> argument for wpa_supplicant to write the current 660 process id into a file 661 6622005-02-12 - v0.3.7 (beginning of 0.3.x stable releases) 663 * added new phase1 option parameter, include_tls_length=1, to force 664 wpa_supplicant to add TLS Message Length field to all TLS messages 665 even if the packet is not fragmented; this may be needed with some 666 authentication servers 667 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when 668 using drivers that take care of AP selection (e.g., when using 669 ap_scan=2) 670 * fixed reprocessing of pending request after ctrl_iface requests for 671 identity/password/otp 672 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of 673 EAP-PEAP and EAP-TTLS 674 * all drivers using driver_wext: set interface up and select Managed 675 mode when starting wpa_supplicant; set interface down when exiting 676 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both 677 ipw2100 and ipw2200; please note that this also changed the 678 configuration variable in .config to CONFIG_DRIVER_IPW 679 6802005-01-24 - v0.3.6 681 * fixed a busy loop introduced in v0.3.5 for scan result processing 682 when no matching AP is found 683 6842005-01-23 - v0.3.5 685 * added a workaround for an interoperability issue with a Cisco AP 686 when using WPA2-PSK 687 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as 688 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow 689 retransmission of dropped frames) 690 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version 691 (e.g., segfault when processing EAPOL-Key frames) 692 * fixed EAP workaround and fast reauthentication configuration for 693 RSN pre-authentication; previously these were disabled and 694 pre-authentication would fail if the used authentication server 695 requires EAP workarounds 696 * added support for blacklisting APs that fail or timeout 697 authentication in ap_scan=1 mode so that all APs are tried in cases 698 where the ones with strongest signal level are failing authentication 699 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS 700 authentication attempt 701 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded 702 in the previous authentication (previously, only Phase 1 success was 703 verified) 704 7052005-01-09 - v0.3.4 706 * added preliminary support for IBSS (ad-hoc) mode configuration 707 (mode=1 in network block); this included a new key_mgmt mode 708 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no 709 key management; see wpa_supplicant.conf for more details and an 710 example on how to configure this (note: this is currently implemented 711 only for driver_hostapd.c, but the changes should be trivial to add 712 in associate() handler for other drivers, too (assuming the driver 713 supports WPA-None) 714 * added preliminary port for native Windows (i.e., no cygwin) using 715 mingw 716 7172005-01-02 - v0.3.3 718 * added optional support for GNU Readline and History Libraries for 719 wpa_cli (CONFIG_READLINE) 720 * cleaned up EAP state machine <-> method interface and number of 721 small problems with error case processing not terminating on 722 EAP-Failure but waiting for timeout 723 * added couple of workarounds for interoperability issues with a 724 Cisco AP when using WPA2 725 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt); 726 Note: This requires a patch for openssl to add support for TLS 727 extensions and number of workarounds for operations without 728 certificates. Proof of concept type of experimental patch is 729 included in openssl-tls-extensions.patch. 730 7312004-12-19 - v0.3.2 732 * fixed private key loading for cases where passphrase is not set 733 * fixed Windows/cygwin L2 packet handler freeing; previous version 734 could cause a segfault when RSN pre-authentication was completed 735 * added support for PMKSA caching with drivers that generate RSN IEs 736 (e.g., NDIS); currently, this is only implemented in driver_ndis.c, 737 but similar code can be easily added to driver_ndiswrapper.c once 738 ndiswrapper gets full support for RSN PMKSA caching 739 * improved recovery from PMKID mismatches by requesting full EAP 740 authentication in case of failed PMKSA caching attempt 741 * driver_ndis: added support for NDIS NdisMIncidateStatus() events 742 (this requires that ndis_events is ran while wpa_supplicant is 743 running) 744 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys 745 * added support for driver interfaces to replace the interface name 746 based on driver/OS specific mapping, e.g., in case of driver_ndis, 747 this allows the beginning of the adapter description to be used as 748 the interface name 749 * added support for CR+LF (Windows-style) line ends in configuration 750 file 751 * driver_ndis: enable radio before starting scanning, disable radio 752 when exiting 753 * modified association event handler to set portEnabled = FALSE before 754 clearing port Valid in order to reset EAP state machine and avoid 755 problems with new authentication getting ignored because of state 756 machines ending up in AUTHENTICATED/SUCCESS state based on old 757 information 758 * added support for driver events to add PMKID candidates in order to 759 allow drivers to give priority to most likely roaming candidates 760 * driver_hostap: moved PrivacyInvoked configuration to associate() 761 function so that this will not be set for plaintext connections 762 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver 763 interface can distinguish plaintext and IEEE 802.1X (no WPA) 764 authentication 765 * fixed static WEP key configuration to use broadcast/default type for 766 all keys (previously, the default TX key was configured as pairwise/ 767 unicast key) 768 * driver_ndis: added legacy WPA capability detection for non-WPA2 769 drivers 770 * added support for setting static WEP keys for IEEE 802.1X without 771 dynamic WEP keying (eapol_flags=0) 772 7732004-12-12 - v0.3.1 774 * added support for reading PKCS#12 (PFX) files (as a replacement for 775 PEM/DER) to get certificate and private key (CONFIG_PKCS12) 776 * fixed compilation with CONFIG_PCSC=y 777 * added new ap_scan mode, ap_scan=2, for drivers that take care of 778 association, but need to be configured with security policy and SSID, 779 e.g., ndiswrapper and NDIS driver; this mode should allow such 780 drivers to work with hidden SSIDs and optimized roaming; when 781 ap_scan=2 is used, only the first network block in the configuration 782 file is used and this configuration should have explicit security 783 policy (i.e., only one option in the lists) for key_mgmt, pairwise, 784 group, proto variables 785 * added experimental port of wpa_supplicant for Windows 786 - driver_ndis.c driver interface (NDIS OIDs) 787 - currently, this requires cygwin and WinPcap 788 - small utility, win_if_list, can be used to get interface name 789 * control interface can now be removed at build time; add 790 CONFIG_CTRL_IFACE=y to .config to maintain old functionality 791 * optional Xsupplicant interface can now be removed at build time; 792 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back) 793 * added auth_alg to driver interface associate() parameters to make it 794 easier for drivers to configure authentication algorithm as part of 795 the association 796 7972004-12-05 - v0.3.0 (beginning of 0.3.x development releases) 798 * driver_broadcom: added new driver interface for Broadcom wl.o driver 799 (a generic driver for Broadcom IEEE 802.11a/g cards) 800 * wpa_cli: fixed parsing of -p <path> command line argument 801 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS 802 ACK, not tunneled EAP-Success (of which only the first byte was 803 actually send due to a bug in previous code); this seems to 804 interoperate with most RADIUS servers that implements PEAPv1 805 * PEAPv1: added support for terminating PEAP authentication on tunneled 806 EAP-Success message; this can be configured by adding 807 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf 808 (some RADIUS servers require this whereas others require a tunneled 809 reply 810 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to 811 the old label for key derivation; previously, the default was 1, 812 but it looks like most existing PEAPv1 implementations use the old 813 label which is thus more suitable default option 814 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt) 815 * fixed parsing of wep_tx_keyidx 816 * added support for configuring list of allowed Phase 2 EAP types 817 (for both EAP-PEAP and EAP-TTLS) instead of only one type 818 * added support for configuring IEEE 802.11 authentication algorithm 819 (auth_alg; mainly for using Shared Key authentication with static 820 WEP keys) 821 * added support for EAP-AKA (with UMTS SIM) 822 * fixed couple of errors in PCSC handling that could have caused 823 random-looking errors for EAP-SIM 824 * added support for EAP-SIM pseudonyms and fast re-authentication 825 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS 826 session resumption) 827 * added support for EAP-SIM with two challanges 828 (phase1="sim_min_num_chal=3" can be used to require three challenges) 829 * added support for configuring DH/DSA parameters for an ephemeral DH 830 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters 831 dh_file and dh_file2 (phase 2); this adds support for using DSA keys 832 and optional DH key exchange to achieve forward secracy with RSA keys 833 * added support for matching subject of the authentication server 834 certificate with a substring when using EAP-TLS/PEAP/TTLS; new 835 configuration variables subject_match and subject_match2 836 * changed SSID configuration in driver_wext.c (used by many driver 837 interfaces) to use ssid_len+1 as the length for SSID since some Linux 838 drivers expect this 839 * fixed couple of unaligned reads in scan result parsing to fix WPA 840 connection on some platforms (e.g., ARM) 841 * added driver interface for Intel ipw2100 driver 842 * added support for LEAP with WPA 843 * added support for larger scan results report (old limit was 4 kB of 844 data, i.e., about 35 or so APs) when using Linux wireless extensions 845 v17 or newer 846 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start 847 only if there is a PMKSA cache entry for the current AP 848 * fixed error handling for case where reading of scan results fails: 849 must schedule a new scan or wpa_supplicant will remain waiting 850 forever 851 * changed debug output to remove shared password/key material by 852 default; all key information can be included with -K command line 853 argument to match the previous behavior 854 * added support for timestamping debug log messages (disabled by 855 default, can be enabled with -t command line argument) 856 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104 857 if keys are not configured to be used; this fixes IEEE 802.1X mode 858 with drivers that use this information to configure whether Privacy 859 bit can be in Beacon frames (e.g., ndiswrapper) 860 * avoid clearing driver keys if no keys have been configured since last 861 key clear request; this seems to improve reliability of group key 862 handshake for ndiswrapper & NDIS driver which seems to be suffering 863 of some kind of timing issue when the keys are cleared again after 864 association 865 * changed driver interface API: 866 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which 867 version is being used (now, this is set to 2; previously, it was 868 not defined) 869 - pass pointer to private data structure to all calls 870 - the new API is not backwards compatible; all in-tree driver 871 interfaces has been converted to the new API 872 * added support for controlling multiple interfaces (radios) per 873 wpa_supplicant process; each interface needs to be listed on the 874 command line (-c, -i, -D arguments) with -N as a separator 875 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi) 876 * added a workaround for EAP servers that incorrectly use same Id for 877 sequential EAP packets 878 * changed libpcap/libdnet configuration to use .config variable, 879 CONFIG_DNET_PCAP, instead of requiring Makefile modification 880 * improved downgrade attack detection in IE verification of msg 3/4: 881 verify both WPA and RSN IEs, if present, not only the selected one; 882 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or 883 Probe Response frame, and RSN is enabled in wpa_supplicant 884 configuration 885 * fixed WPA msg 3/4 processing to allow Key Data field contain other 886 IEs than just one WPA IE 887 * added support for FreeBSD and driver interface for the BSD net80211 888 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the 889 required kernel mods have not yet been committed 890 * made EAP workarounds configurable; enabled by default, can be 891 disabled with network block option eap_workaround=0 892 8932004-07-17 - v0.2.4 (beginning of 0.2.x stable releases) 894 * resolved couple of interoperability issues with EAP-PEAPv1 and 895 Phase 2 (inner EAP) fragment reassembly 896 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the 897 AP is using non-zero key index for the unicast key and key index zero 898 for the broadcast key 899 * driver_hostap: fixed IEEE 802.1X WEP key updates and 900 re-authentication by allowing unencrypted EAPOL frames when not using 901 WPA 902 * added a new driver interface, 'wext', which uses only standard, 903 driver independent functionality in Linux wireless extensions; 904 currently, this can be used only for non-WPA IEEE 802.1X mode, but 905 eventually, this is to be extended to support full WPA/WPA2 once 906 Linux wireless extensions get support for this 907 * added support for mode in which the driver is responsible for AP 908 scanning and selection; this is disabled by default and can be 909 enabled with global ap_scan=0 variable in wpa_supplicant.conf; 910 this mode can be used, e.g., with generic 'wext' driver interface to 911 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver 912 supporting wireless extensions. 913 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g., 914 operation with an AP that does not include SSID in the Beacon frames) 915 * added support for new EAP authentication methods: 916 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP 917 * added support for asking one-time-passwords from frontends (e.g., 918 wpa_cli); this 'otp' command works otherwise like 'password' command, 919 but the password is used only once and the frontend will be asked for 920 a new password whenever a request from authenticator requires a 921 password; this can be used with both EAP-OTP and EAP-GTC 922 * changed wpa_cli to automatically re-establish connection so that it 923 does not need to be re-started when wpa_supplicant is terminated and 924 started again 925 * improved user data (identity/password/otp) requests through 926 frontends: process pending EAPOL packets after getting new 927 information so that full authentication does not need to be 928 restarted; in addition, send pending requests again whenever a new 929 frontend is attached 930 * changed control frontends to use a new directory for socket files to 931 make it easier for wpa_cli to automatically select between interfaces 932 and to provide access control for the control interface; 933 wpa_supplicant.conf: ctrl_interface is now a path 934 (/var/run/wpa_supplicant is the recommended path) and 935 ctrl_interface_group can be used to select which group gets access to 936 the control interface; 937 wpa_cli: by default, try to connect to the first interface available 938 in /var/run/wpa_supplicant; this path can be overriden with -p option 939 and an interface can be selected with -i option (i.e., in most common 940 cases, wpa_cli does not need to get any arguments) 941 * added support for LEAP 942 * added driver interface for Linux ndiswrapper 943 * added priority option for network blocks in the configuration file; 944 this allows networks to be grouped based on priority (the scan 945 results are searched for matches with network blocks in this order) 946 9472004-06-20 - v0.2.3 948 * sort scan results to improve AP selection 949 * fixed control interface socket removal for some error cases 950 * improved scan requesting and authentication timeout 951 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and 952 TLS processing 953 * PEAP version can now be forced with phase1="peapver=<ver>" 954 (mostly for testing; by default, the highest version supported by 955 both the Supplicant and Authentication Server is selected 956 automatically) 957 * added support for madwifi driver (Atheros ar521x) 958 * added a workaround for cases where AP sets Install Tx/Rx bit for 959 WPA Group Key messages when pairwise keys are used (without this, 960 the Group Key would be used for Tx and the AP would drop frames 961 from the station) 962 * added GSM SIM/USIM interface for GSM authentication algorithm for 963 EAP-SIM; this requires pcsc-lite 964 * added support for ATMEL AT76C5XXx driver 965 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator 966 does not include key data in the EAPOL-Key frame (i.e., part of 967 EAP keying material is used as data encryption key) 968 * added support for using plaintext and static WEP networks 969 (key_mgmt=NONE) 970 9712004-05-31 - v0.2.2 972 * added support for new EAP authentication methods: 973 EAP-TTLS/EAP-MD5-Challenge 974 EAP-TTLS/EAP-GTC 975 EAP-TTLS/EAP-MSCHAPv2 976 EAP-TTLS/EAP-TLS 977 EAP-TTLS/MSCHAPv2 978 EAP-TTLS/MSCHAP 979 EAP-TTLS/PAP 980 EAP-TTLS/CHAP 981 EAP-PEAP/TLS 982 EAP-PEAP/GTC 983 EAP-PEAP/MD5-Challenge 984 EAP-GTC 985 EAP-SIM (not yet complete; needs GSM/SIM authentication interface) 986 * added support for anonymous identity (to be used when identity is 987 sent in plaintext; real identity will be used within TLS protected 988 tunnel (e.g., with EAP-TTLS) 989 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli 990 * added support for requesting identity and password information using 991 control interface; in other words, the password for EAP-PEAP or 992 EAP-TTLS does not need to be included in the configuration file since 993 a frontand (e.g., wpa_cli) can ask it from the user 994 * improved RSN pre-authentication to use a candidate list and process 995 all candidates from each scan; not only one per scan 996 * fixed RSN IE and WPA IE capabilities field parsing 997 * ignore Tx bit in GTK IE when Pairwise keys are used 998 * avoid making new scan requests during IEEE 802.1X negotiation 999 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant 1000 with TLS support (this replaces the included implementation with 1001 library code to save about 8 kB since the library code is needed 1002 anyway for TLS) 1003 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support 1004 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config) 1005 10062004-05-06 - v0.2.1 1007 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1) 1008 Supplicant 1009 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1] 1010 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf] 1011 - EAP-MD5 (cannot be used with WPA-RADIUS) 1012 [draft-ietf-eap-rfc2284bis-09.txt] 1013 - EAP-TLS [RFC 2716] 1014 - EAP-MSCHAPv2 (currently used only with EAP-PEAP) 1015 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt] 1016 [draft-kamath-pppext-eap-mschapv2-00.txt] 1017 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by 1018 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey) 1019 - new configuration file options: eap, identity, password, ca_cert, 1020 client_cert, privatekey, private_key_passwd 1021 - Xsupplicant is not required anymore, but it can be used by 1022 disabling the internal IEEE 802.1X Supplicant with -e command line 1023 option 1024 - this code is not included in the default build; Makefile need to 1025 be edited for this (uncomment lines for selected functionality) 1026 - EAP-TLS and EAP-PEAP require openssl libraries 1027 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..) 1028 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys 1029 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X 1030 EAPOL-Key frames instead of WPA key handshakes) 1031 * added support for IEEE 802.11i/RSN (WPA2) 1032 - improved PTK Key Handshake 1033 - PMKSA caching, pre-authentication 1034 * fixed wpa_supplicant to ignore possible extra data after WPA 1035 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using 1036 TPTK' error from message 3 of 4-Way Handshake in case the AP 1037 includes extra data after the EAPOL-Key) 1038 * added interface for external programs (frontends) to control 1039 wpa_supplicant 1040 - CLI example (wpa_cli) with interactive mode and command line 1041 mode 1042 - replaced SIGUSR1 status/statistics with the new control interface 1043 * made some feature compile time configurable 1044 - .config file for make 1045 - driver interfaces (hostap, hermes, ..) 1046 - EAPOL/EAP functions 1047 10482004-02-15 - v0.2.0 1049 * Initial version of wpa_supplicant 1050
