1 ChangeLog for wpa_supplicant
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 * allow multiple driver wrappers to be specified on command line
9 (e.g., -Dnl80211,wext); the first one that is able to initialize the
10 interface will be used
11 * added support for multiple SSIDs per scan request to optimize
12 scan_ssid=1 operations in ap_scan=1 mode (i.e., search for hidden
13 SSIDs); this requires driver support and can currently be used only
17 * added support for Wi-Fi Protected Setup (WPS)
18 (wpa_supplicant can now be configured to act as a WPS Enrollee to
19 enroll credentials for a network using PIN and PBC methods; in
20 addition, wpa_supplicant can act as a wireless WPS Registrar to
21 configure an AP); WPS support can be enabled by adding CONFIG_WPS=y
22 into .config and setting the runtime configuration variables in
23 wpa_supplicant.conf (see WPS section in the example configuration
24 file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to
25 manage WPS negotiation; see README-WPS for more details
26 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
27 * added support for using driver_test over UDP socket
28 * fixed PEAPv0 Cryptobinding interoperability issue with Windows Server
29 2008 NPS; optional cryptobinding is now enabled (again) by default
30 * fixed PSK editing in wpa_gui
31 * changed EAP-GPSK to use the IANA assigned EAP method type 51
32 * added a Windows installer that includes WinPcap and all the needed
33 DLLs; in addition, it set up the registry automatically so that user
34 will only need start wpa_gui to get prompted to start the wpasvc
35 servide and add a new interface if needed through wpa_gui dialog
36 * updated management frame protection to use IEEE 802.11w/D7.0
39 * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
40 (can be used to simulate test SIM/USIM card with a known private key;
41 enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
42 and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
43 * added a new network configuration option, wpa_ptk_rekey, that can be
44 used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
45 against TKIP deficiencies
46 * added an optional mitigation mechanism for certain attacks against
47 TKIP by delaying Michael MIC error reports by a random amount of time
48 between 0 and 60 seconds; this can be enabled with a build option
49 CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
50 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
52 * updated OpenSSL code for EAP-FAST to use an updated version of the
53 session ticket overriding API that was included into the upstream
54 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
55 needed with that version anymore)
56 * updated userspace MLME instructions to match with the current Linux
57 mac80211 implementation; please also note that this can only be used
58 with driver_nl80211.c (the old code from driver_wext.c was removed)
59 * added support (Linux only) for RoboSwitch chipsets (often found in
60 consumer grade routers); driver interface 'roboswitch'
61 * fixed canceling of PMKSA caching when using drivers that generate
62 RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
66 * added support for SHA-256 as X.509 certificate digest when using the
67 internal X.509/TLSv1 implementation
68 * updated management frame protection to use IEEE 802.11w/D6.0
69 * added support for using SHA256-based stronger key derivation for WPA2
71 * fixed FT (IEEE 802.11r) authentication after a failed association to
73 * added support for configuring Phase 2 (inner/tunneled) authentication
74 method with wpa_gui-qt4
77 * added support for EAP Sequences in EAP-FAST Phase 2
78 * added support for using TNC with EAP-FAST
79 * added driver_ps3 for the PS3 Linux wireless driver
80 * added support for optional cryptobinding with PEAPv0
81 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
82 allow fallback to full handshake if server rejects PAC-Opaque
83 * added fragmentation support for EAP-TNC
84 * added support for parsing PKCS #8 formatted private keys into the
85 internal TLS implementation (both PKCS #1 RSA key and PKCS #8
86 encapsulated RSA key can now be used)
87 * added option of using faster, but larger, routines in the internal
88 LibTomMath (for internal TLS implementation) to speed up DH and RSA
89 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
90 * fixed race condition between disassociation event and group key
91 handshake to avoid getting stuck in incorrect state [Bug 261]
92 * fixed opportunistic key caching (proactive_key_caching)
95 * removed 'nai' and 'eappsk' network configuration variables that were
96 previously used for configuring user identity and key for EAP-PSK,
97 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
98 replacement for 'nai' (if old configuration used a separate
99 'identity' value, that would now be configured as
100 'anonymous_identity'). 'password' field is now used as the
101 replacement for 'eappsk' (it can also be set using hexstring to
102 present random binary data)
103 * removed '-w' command line parameter (wait for interface to be added,
104 if needed); cleaner way of handling this functionality is to use an
105 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
106 when an interface is added
107 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
108 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
109 indicating when new scan results become available
110 * added new ctrl_iface command, BSS, to allow scan results to be
111 fetched without hitting the message size limits (this command
112 can be used to iterate through the scan results one BSS at the time)
113 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
114 attributes in EAP-SIM Start/Response when using fast reauthentication
115 * fixed EAPOL not to end up in infinite loop when processing dynamic
116 WEP keys with IEEE 802.1X
117 * fixed problems in getting NDIS events from WMI on Windows 2000
120 * added support for Makefile builds to include debug-log-to-a-file
121 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
122 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
123 lengths properly to avoid potential crash caused by invalid messages
124 * added data structure for storing allocated buffers (struct wpabuf);
125 this does not affect wpa_supplicant usage, but many of the APIs
126 changed and various interfaces (e.g., EAP) is not compatible with old
128 * added support for protecting EAP-AKA/Identity messages with
129 AT_CHECKCODE (optional feature in RFC 4187)
130 * added support for protected result indication with AT_RESULT_IND for
131 EAP-SIM and EAP-AKA (phase1="result_ind=1")
132 * added driver_wext workaround for race condition between scanning and
133 association with drivers that take very long time to scan all
134 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
135 using a longer hardcoded timeout for the scan if the driver supports
136 notifications for scan completion (SIOCGIWSCAN event); this helps,
137 e.g., in cases where wpa_supplicant and madwifi driver ended up in
138 loop where the driver did not even try to associate
139 * stop EAPOL timer tick when no timers are in use in order to reduce
140 power consumption (no need to wake up the process once per second)
142 * added support for privilege separation (run only minimal part of
143 wpa_supplicant functionality as root and rest as unprivileged,
144 non-root process); see 'Privilege separation' in README for details;
145 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
147 * changed scan results data structure to include all information
148 elements to make it easier to support new IEs; old get_scan_result()
149 driver_ops is still supported for backwards compatibility (results
150 are converted internally to the new format), but all drivers should
151 start using the new get_scan_results2() to make them more likely to
152 work with new features
153 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
154 application, i.e., it does not require Qt3Support anymore; Windows
155 binary of wpa_gui.exe is now from this directory and only requires
156 QtCore4.dll and QtGui4.dll libraries
157 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
158 available as a separate package to make wpa_gui installation easier:
159 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
160 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
161 only shared key/password authentication is supported in this version
164 * added support for configuring password as NtPasswordHash
165 (16-byte MD4 hash of password) in hash:<32 hex digits> format
166 * added support for fallback from abbreviated TLS handshake to
167 full handshake when using EAP-FAST (e.g., due to an expired
169 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
170 draft (draft-ietf-emu-eap-gpsk-07.txt)
171 * added support for drivers that take care of RSN 4-way handshake
172 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
173 WPA_ALG_PMK in set_key)
174 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
175 .config); this version supports only ap_scan=2 mode and allow the
176 driver to take care of the 4-way handshake
177 * fixed a buffer overflow in parsing TSF from scan results when using
178 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
180 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
181 * fixed an integer overflow issue in the ASN.1 parser used by the
182 (experimental) internal TLS implementation to avoid a potential
184 * fixed a race condition with -W option (wait for a control interface
185 monitor before starting) that could have caused the first messages to
187 * added support for processing TNCC-TNCS-Messages to report
188 recommendation (allow/none/isolate) when using TNC [Bug 243]
191 * added network configuration parameter 'frequency' for setting
192 initial channel for IBSS (adhoc) networks
193 * added experimental IEEE 802.11r/D6.0 support
194 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
195 * updated EAP-PSK to use the IANA-allocated EAP type 47
196 * fixed EAP-PAX key derivation
197 * fixed EAP-PSK bit ordering of the Flags field
198 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
199 tunnelled identity request (previously, the identifier from the outer
200 method was used, not the tunnelled identifier which could be
202 * added support for fragmentation of outer TLS packets during Phase 2
203 of EAP-PEAP/TTLS/FAST
204 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
205 * added support for EAP-FAST authentication with inner methods that
206 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
207 for PAC provisioning)
208 * added support for authenticated EAP-FAST provisioning
209 * added support for configuring maximum number of EAP-FAST PACs to
210 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
211 * added support for storing EAP-FAST PACs in binary format
212 (fast_pac_format=binary in phase1 string)
213 * fixed dbus ctrl_iface to validate message interface before
214 dispatching to avoid a possible segfault [Bug 190]
215 * fixed PeerKey key derivation to use the correct PRF label
216 * updated Windows binary build to link against OpenSSL 0.9.8d and
217 added support for EAP-FAST
218 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
219 draft (draft-ietf-emu-eap-gpsk-04.txt)
220 * fixed EAP-AKA Notification processing to allow Notification to be
221 processed after AKA Challenge response has been sent
222 * updated to use IEEE 802.11w/D2.0 for management frame protection
224 * fixed EAP-TTLS implementation not to crash on use of freed memory
225 if TLS library initialization fails
226 * added support for EAP-TNC (Trusted Network Connect)
227 (this version implements the EAP-TNC method and EAP-TTLS changes
228 needed to run two methods in sequence (IF-T) and the IF-IMC and
229 IF-TNCCS interfaces from TNCC)
232 * added experimental, integrated TLSv1 client implementation with the
233 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
234 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
235 .config); this can be useful, e.g., if the target system does not
236 have a suitable TLS library and a minimal code size is required
237 (total size of this internal TLS/crypto code is bit under 50 kB on
238 x86 and the crypto code is shared by rest of the supplicant so some
239 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
240 * removed STAKey handshake since PeerKey handshake has replaced it in
241 IEEE 802.11ma and there are no known deployments of STAKey
242 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
243 draft (draft-ietf-emu-eap-gpsk-01.txt)
244 * added preliminary implementation of IEEE 802.11w/D1.0 (management
246 (Note: this requires driver support to work properly.)
247 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
248 * fixed Windows named pipes ctrl_iface to not stop listening for
249 commands if client program opens a named pipe and closes it
250 immediately without sending a command
251 * fixed USIM PIN status determination for the case that PIN is not
252 needed (this allows EAP-AKA to be used with USIM cards that do not
254 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
255 be used with cards that do not support file selection based on
257 * added support for matching the subjectAltName of the authentication
258 server certificate against multiple name components (e.g.,
259 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
260 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
261 affects IEEE 802.1X with dynamic WEP keys)
262 * changed ctrl_iface network configuration 'get' operations to not
263 return password/key material; if these fields are requested, "*"
264 will be returned if the password/key is set, but the value of the
265 parameter is not exposed
268 * added support for building Windows version with UNICODE defined
269 (wide-char functions)
270 * driver_ndis: fixed static WEP configuration to avoid race condition
271 issues with some NDIS drivers between association and setting WEP
273 * driver_ndis: added validation for IELength value in scan results to
274 avoid crashes when using buggy NDIS drivers [Bug 165]
275 * fixed Release|Win32 target in the Visual Studio project files
276 (previously, only Debug|Win32 target was set properly)
277 * changed control interface API call wpa_ctrl_pending() to allow it to
278 return -1 on error (e.g., connection lost); control interface clients
279 will need to make sure that they verify that the value is indeed >0
280 when determining whether there are pending messages
281 * added an alternative control interface backend for Windows targets:
282 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
283 control interface mechanism for Windows builds (previously, UDP to
285 * changed ctrl_interface configuration for UNIX domain sockets:
286 - deprecated ctrl_interface_group variable (it may be removed in
288 - allow both directory and group be configured with ctrl_interface
289 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
290 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
291 case when group is not changed
292 * added support for controlling more than one interface per process in
294 * added a workaround for a case where the AP is using unknown address
295 (e.g., MAC address of the wired interface) as the source address for
296 EAPOL-Key frames; previously, that source address was used as the
297 destination for EAPOL-Key frames and in key derivation; now, BSSID is
298 used even if the source address does not match with it
299 (this resolves an interoperability issue with Thomson SpeedTouch 580)
300 * added a workaround for UDP-based control interface (which was used in
301 Windows builds before this release) to prevent packets with forged
302 addresses from being accepted as local control requests
303 * removed ndis_events.cpp and possibility of using external
304 ndis_events.exe; C version (ndis_events.c) is fully functional and
305 there is no desire to maintain two separate versions of this
307 * ndis_events: Changed NDIS event notification design to use WMI to
308 learn the adapter description through Win32_PnPEntity class; this
309 should fix some cases where the adapter name was not recognized
310 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
312 * fixed selection of the first network in ap_scan=2 mode; previously,
313 wpa_supplicant could get stuck in SCANNING state when only the first
314 network for enabled (e.g., after 'wpa_cli select_network 0')
315 * winsvc: added support for configuring ctrl_interface parameters in
316 registry (ctrl_interface string value in
317 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
318 required to enable control interface (previously, this was hardcoded
320 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
321 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
324 * fixed build with CONFIG_STAKEY=y [Bug 143]
325 * added support for doing MLME (IEEE 802.11 management frame
326 processing) in wpa_supplicant when using Devicescape IEEE 802.11
327 stack (wireless-dev.git tree)
328 * added a new network block configuration option, fragment_size, to
329 configure the maximum EAP fragment size
330 * driver_ndis: Disable WZC automatically for the selected interface to
331 avoid conflicts with two programs trying to control the radio; WZC
332 will be re-enabled (if it was enabled originally) when wpa_supplicant
334 * added an experimental TLSv1 client implementation
335 (CONFIG_TLS=internal) that can be used instead of an external TLS
336 library, e.g., to reduce total size requirement on systems that do
337 not include any TLS library by default (this is not yet complete;
338 basic functionality is there, but certificate validation is not yet
340 * added PeerKey handshake implementation for IEEE 802.11e
341 direct link setup (DLS) to replace STAKey handshake
342 * fixed WPA PSK update through ctrl_iface for the case where the old
343 PSK was derived from an ASCII passphrase and the new PSK is set as
344 a raw PSK (hex string)
345 * added new configuration option for identifying which network block
346 was used (id_str in wpa_supplicant.conf; included on
347 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
348 variable in wpa_cli action scripts; in addition WPA_ID variable is
349 set to the current unique identifier that wpa_supplicant assigned
350 automatically for the network and that can be used with
351 GET_NETWORK/SET_NETWORK ctrl_iface commands)
352 * wpa_cli action script is now called only when the connect/disconnect
353 status changes or when associating with a different network
354 * fixed configuration parser not to remove CCMP from group cipher list
355 if WPA-None (adhoc) is used (pairwise=NONE in that case)
356 * fixed integrated NDIS events processing not to hang the process due
357 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
358 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
359 draft-clancy-emu-eap-shared-secret-00.txt)
360 * added Microsoft Visual Studio 2005 solution and project files for
361 build wpa_supplicant for Windows (see vs2005 subdirectory)
362 * eloop_win: fixed unregistration of Windows events
363 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
364 at the end of RSN pre-authentication and added unregistration of
365 a Windows event to avoid getting eloop_win stuck with an invalid
367 * driver_ndis: added support for selecting AP based on BSSID
368 * added new environmental variable for wpa_cli action scripts:
369 WPA_CTRL_DIR is the current control interface directory
370 * driver_ndis: added support for using NDISUIO instead of WinPcap for
371 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
372 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
373 wpa_supplicant without requiring WinPcap; note that using NDISUIO
374 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
375 only one application to open the device
376 * changed NDIS driver naming to only include device GUID, e.g.,
377 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
378 specific \Device\NPF_ prefix before the GUID; the prefix is still
379 allowed for backwards compatibility, but it is not required anymore
380 when specifying the interface
381 * driver_ndis: re-initialize driver interface is the adapter is removed
382 and re-inserted [Bug 159]
383 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
384 big endian hosts [Bug 146]
387 * fixed EAP-GTC response to include correct user identity when run as
388 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
389 * driver_ndis: Fixed encryption mode configuration for unencrypted
390 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
391 refused to associate with open networks) [Bug 106]
392 * driver_ndis: use BSSID OID polling to detect when IBSS network is
393 formed even when ndis_events code is included since some NDIS drivers
394 do not generate media connect events in IBSS mode
395 * config_winreg: allow global ctrl_interface parameter to be configured
397 * config_winreg: added support for saving configuration data into
399 * added support for controlling network device operational state
400 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
401 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
402 that can use this information)
403 * driver_wext: added support for WE-21 change to SSID configuration
404 * driver_wext: fixed privacy configuration for static WEP keys mode
406 * added an optional driver_ops callback for MLME-SETPROTECTION.request
408 * added support for EAP-SAKE (no EAP method number allocated yet, so
409 this is using the same experimental type 255 as EAP-PSK)
410 * added support for dynamically loading EAP methods (.so files) instead
411 of requiring them to be statically linked in; this is disabled by
412 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
416 * do not try to use USIM APDUs when initializing PC/SC for SIM card
417 access for a network that has not enabled EAP-AKA
418 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
419 v0.5.1 due to the new support for expanded EAP types)
420 * added support for generating EAP Expanded Nak
421 * try to fetch scan results once before requesting new scan when
422 starting up in ap_scan=1 mode (this can speed up initial association
423 a lot with, e.g., madwifi-ng driver)
424 * added support for receiving EAPOL frames from a Linux bridge
425 interface (-bbr0 on command line)
426 * fixed EAPOL re-authentication for sessions that used PMKSA caching
427 * changed EAP method registration to use a dynamic list of methods
428 instead of a static list generated at build time
429 * fixed PMKSA cache deinitialization not to use freed memory when
430 removing PMKSA entries
431 * fixed a memory leak in EAP-TTLS re-authentication
432 * reject WPA/WPA2 message 3/4 if it does not include any valid
434 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
435 if the driver does not support SIOCSIWAUTH
438 * driver_test: added better support for multiple APs and STAs by using
439 a directory with sockets that include MAC address for each device in
440 the name (driver_param=test_dir=/tmp/test)
441 * added support for EAP expanded type (vendor specific EAP methods)
442 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
443 option can be changed if needed
444 * wpa_cli/wpa_gui: skip non-socket files in control directory when
445 using UNIX domain sockets; this avoids selecting an incorrect
446 interface (e.g., a PID file could be in this directory, even though
447 use of this directory for something else than socket files is not
449 * fixed TLS library deinitialization after RSN pre-authentication not
450 to disable TLS library for normal authentication
451 * driver_wext: Remove null-termination from SSID length if the driver
452 used it; some Linux drivers do this and they were causing problems in
453 wpa_supplicant not finding matching configuration block. This change
454 would break a case where the SSID actually ends in '\0', but that is
455 not likely to happen in real use.
456 * fixed PMKSA cache processing not to trigger deauthentication if the
457 current PMKSA cache entry is replaced with a valid new entry
458 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
459 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
462 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
463 * added experimental STAKey handshake implementation for IEEE 802.11e
464 direct link setup (DLS); note: this is disabled by default in both
465 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
467 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
468 decrypt AT_ENCR_DATA attributes correctly
469 * fixed EAP-AKA to allow resynchronization within the same session
470 * made code closer to ANSI C89 standard to make it easier to port to
471 other C libraries and compilers
472 * started moving operating system or C library specific functions into
473 wrapper functions defined in os.h and implemented in os_*.c to make
475 * wpa_supplicant can now be built with Microsoft Visual C++
476 (e.g., with the freely available Toolkit 2003 version or Visual
477 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
478 example makefile for nmake
479 * added support for using Windows registry for command line parameters
480 (CONFIG_MAIN=main_winsvc) and configuration data
481 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
482 contents; this version can be run both as a Windows service and as a
483 normal application; 'wpasvc.exe app' to start as applicant,
484 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
485 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
487 * made it possible to link ndis_events.exe functionality into
488 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
489 * added better support for multiple control interface backends
490 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
491 * fixed PC/SC code to use correct length for GSM AUTH command buffer
492 and to not use pioRecvPci with SCardTransmit() calls; these were not
493 causing visible problems with pcsc-lite, but Windows Winscard.dll
494 refused the previously used parameters; this fixes EAP-SIM and
495 EAP-AKA authentication using SIM/USIM card under Windows
496 * added new event loop implementation for Windows using
497 WaitForMultipleObject() instead of select() in order to allow waiting
498 for non-socket objects; this can be selected with
499 CONFIG_ELOOP=eloop_win in .config
500 * added support for selecting l2_packet implementation in .config
501 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
502 winpcap, freebsd, none)
503 * added new l2_packet implementation for WinPcap
504 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
505 reduce latency in EAPOL receive processing from about 100 ms to about
507 * added support for EAP-FAST key derivation using other ciphers than
508 RC4-128-SHA for authentication and AES128-SHA for provisioning
509 * added support for configuring CA certificate as DER file and as a
511 * fixed private key configuration as configuration blob and added
512 support for using PKCS#12 as a blob
513 * tls_gnutls: added support for using PKCS#12 files; added support for
515 * added support for loading trusted CA certificates from Windows
516 certificate store: ca_cert="cert_store://<name>", where <name> is
517 likely CA (Intermediate CA certificates) or ROOT (root certificates)
518 * added C version of ndis_events.cpp and made it possible to build this
519 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
520 easily on cross-compilation builds
521 * added wpasvc.exe into Windows binary release; this is an alternative
522 version of wpa_supplicant.exe with configuration backend using
523 Windows registry and with the entry point designed to run as a
525 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
526 wpasvc.exe and removed this additional tool from the Windows binary
527 release since it is not needed anymore
528 * load winscard.dll functions dynamically when building with MinGW
529 since MinGW does not yet include winscard library
531 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
532 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
533 and WinPcap to receive frames sent to PAE group address
534 * disable EAP state machine when IEEE 802.1X authentication is not used
535 in order to get rid of bogus "EAP failed" messages
536 * fixed OpenSSL error reporting to go through all pending errors to
537 avoid confusing reports of old errors being reported at later point
539 * fixed configuration file updating to not write empty variables
540 (e.g., proto or key_mgmt) that the file parser would not accept
541 * fixed ADD_NETWORK ctrl_iface command to use the same default values
542 for variables as empty network definitions read from config file
544 * fixed EAP state machine to not discard EAP-Failure messages in many
545 cases (e.g., during TLS handshake)
546 * fixed a infinite loop in private key reading if the configured file
547 cannot be parsed successfully
548 * driver_madwifi: added support for madwifi-ng
549 * wpa_gui: do not display password/PSK field contents
550 * wpa_gui: added CA certificate configuration
551 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
552 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
553 the new AP is using different WPA/RSN IE
554 * use longer timeout for IEEE 802.11 association to avoid problems with
555 drivers that may take more than five second to associate
558 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
559 RSN IE, but WPA IE would match with wpa_supplicant configuration
560 * added support for named configuration blobs in order to avoid having
561 to use file system for external files (e.g., certificates);
562 variables can be set to "blob://<blob name>" instead of file path to
563 use a named blob; supported fields: pac_file, client_cert,
565 * fixed RSN pre-authentication (it was broken in the clean up of WPA
566 state machine interface in v0.4.5)
567 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
568 sure the driver configures broadcast decryption correctly
569 * added ca_path (and ca_path2) configuration variables that can be used
570 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
571 system-wide trusted CA list
572 * added support for starting wpa_supplicant without a configuration
573 file (-C argument must be used to set ctrl_interface parameter for
574 this case; in addition, -p argument can be used to provide
575 driver_param; these new arguments can also be used with a
576 configuration to override the values from the configuration)
577 * added global control interface that can be optionally used for adding
578 and removing network interfaces dynamically (-g command line argument
579 for both wpa_supplicant and wpa_cli) without having to restart
580 wpa_supplicant process
582 - try to save configuration whenever something is modified
583 - added WEP key configuration
584 - added possibility to edit the current network configuration
585 * driver_ndis: fixed driver polling not to increase frequency on each
586 received EAPOL frame due to incorrectly cancelled timeout
587 * added simple configuration file examples (in examples subdirectory)
588 * fixed driver_wext.c to filter wireless events based on ifindex to
589 avoid interfaces receiving events from other interfaces
590 * delay sending initial EAPOL-Start couple of seconds to speed up
591 authentication for the most common case of Authenticator starting
592 EAP authentication immediately after association
595 * added a workaround for clearing keys with ndiswrapper to allow
596 roaming from WPA enabled AP to plaintext one
597 * added docbook documentation (doc/docbook) that can be used to
598 generate, e.g., man pages
599 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
600 PF_PACKET in order to prepare for network devices that do not use
601 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
602 * use receipt of EAPOL-Key frame as a lower layer success indication
603 for EAP state machine to allow recovery from dropped EAP-Success
605 * cleaned up internal EAPOL frame processing by not including link
606 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
607 header is added only when transmitted the frame; this makes it easier
608 to use wpa_supplicant on link layers that use different header than
610 * updated EAP-PSK to use draft 9 by default since this can now be
611 tested with hostapd; removed support for draft 3, including
612 server_nai configuration option from network blocks
613 * driver_wired: add PAE address to the multicast address list in order
614 to be able to receive EAPOL frames with drivers that do not include
615 these multicast addresses by default
616 * driver_wext: add support for WE-19
617 * added support for multiple configuration backends (CONFIG_BACKEND
618 option); currently, only 'file' is supported (i.e., the format used
619 in wpa_supplicant.conf)
620 * added support for updating configuration ('wpa_cli save_config');
621 this is disabled by default and can be enabled with global
622 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
623 and wpa_gui to store the configuration changes in a permanent store
624 * added GET_NETWORK ctrl_iface command
625 (e.g., 'wpa_cli get_network 0 ssid')
628 * replaced OpenSSL patch for EAP-FAST support
629 (openssl-tls-extensions.patch) with a more generic and correct
630 patch (the new patch is not compatible with the previous one, so the
631 OpenSSL library will need to be patched with the new patch in order
632 to be able to build wpa_supplicant with EAP-FAST support)
633 * added support for using Windows certificate store (through CryptoAPI)
634 for client certificate and private key operations (EAP-TLS)
635 (see wpa_supplicant.conf for more information on how to configure
636 this with private_key)
637 * ported wpa_gui to Windows
638 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
639 built with the open source version of the Qt4 for Windows
640 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
641 with drivers that do not support WPA
642 * ndis_events: fixed Windows 2000 support
643 * added support for enabling/disabling networks from the list of all
644 configured networks ('wpa_cli enable_network <network id>' and
645 'wpa_cli disable_network <network id>')
646 * added support for adding and removing network from the current
647 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
648 <network id>'); added networks are disabled by default and they can
649 be enabled with enable_network command once the configuration is done
650 for the new network; note: configuration file is not yet updated, so
651 these new networks are lost when wpa_supplicant is restarted
652 * added support for setting network configuration parameters through
653 the control interface, for example:
654 wpa_cli set_network 0 ssid "\"my network\""
655 * fixed parsing of strings that include both " and # within double
656 quoted area (e.g., "start"#end")
657 * added EAP workaround for PEAP session resumption: allow outer,
658 i.e., not tunneled, EAP-Success to terminate session since; this can
659 be disabled with eap_workaround=0
660 (this was allowed for PEAPv1 before, but now it is also allowed for
661 PEAPv0 since at least one RADIUS authentication server seems to be
662 doing this for PEAPv0, too)
663 * wpa_gui: added preliminary support for adding new networks to the
664 wpa_supplicant configuration (double click on the scan results to
665 open network configuration)
668 * removed interface for external EAPOL/EAP supplicant (e.g.,
669 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
670 anymore and is unlikely to be used by anyone
671 * driver_ndis: fixed WinPcap 3.0 support
672 * fixed build with CONFIG_DNET_PCAP=y on Linux
673 * l2_packet: moved different implementations into separate files
677 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
678 (note: ipw2100-1.1.0 is likely to require an update to work with
680 * added support for using ap_scan=2 mode with multiple network blocks;
681 wpa_supplicant will go through the networks one by one until the
682 driver reports a successful association; this uses the same order for
683 networks as scan_ssid=1 scans, i.e., the priority field is ignored
684 and the network block order in the file is used instead
685 * fixed a potential issue in RSN pre-authentication ending up using
686 freed memory if pre-authentication times out
687 * added support for matching alternative subject name extensions of the
688 authentication server certificate; new configuration variables
689 altsubject_match and altsubject_match2
690 * driver_ndis: added support for IEEE 802.1X authentication with wired
692 * added support for querying private key password (EAP-TLS) through the
693 control interface (wpa_cli/wpa_gui) if one is not included in the
695 * driver_broadcom: fixed couple of memory leaks in scan result
697 * EAP-PAX is now registered as EAP type 46
698 * fixed EAP-PAX MAC calculation
699 * fixed EAP-PAX CK and ICK key derivation
700 * added support for using password with EAP-PAX (as an alternative to
701 entering key with eappsk); SHA-1 hash of the password will be used as
703 * added support for arbitrary driver interface parameters through the
704 configuration file with a new driver_param field; this adds a new
705 driver_ops function set_param()
706 * added possibility to override l2_packet module with driver interface
707 API (new send_eapol handler); this can be used to implement driver
708 specific TX/RX functions for EAPOL frames
709 * fixed ctrl_interface_group processing for the case where gid is
710 entered as a number, not group name
711 * driver_test: added support for testing hostapd with wpa_supplicant
712 by using test driver interface without any kernel drivers or network
716 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
717 packets to be encrypted; this was apparently broken by the changed
718 ioctl order in v0.4.0
719 * driver_madwifi: added preliminary support for compiling against 'BSD'
720 branch of madwifi CVS tree
721 * added support for EAP-MSCHAPv2 password retries within the same EAP
722 authentication session
723 * added support for password changes with EAP-MSCHAPv2 (used when the
724 password has expired)
725 * added support for reading additional certificates from PKCS#12 files
726 and adding them to the certificate chain
727 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
729 * fixed a possible double free in EAP-TTLS fast-reauthentication when
730 identity or password is entered through control interface
731 * display EAP Notification messages to user through control interface
732 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
733 * added GUI version of wpa_cli, wpa_gui; this is not build
734 automatically with 'make'; use 'make wpa_gui' to build (this requires
735 Qt development tools)
736 * added 'disconnect' command to control interface for setting
737 wpa_supplicant in state where it will not associate before
738 'reassociate' command has been used
739 * added support for selecting a network from the list of all configured
740 networks ('wpa_cli select_network <network id>'; this disabled all
741 other networks; to re-enable, 'wpa_cli select_network any')
742 * added support for getting scan results through control interface
743 * added EAP workaround for PEAPv1 session resumption: allow outer,
744 i.e., not tunneled, EAP-Success to terminate session since; this can
745 be disabled with eap_workaround=0
747 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
748 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
749 used to reduce the size of the wpa_supplicant considerably if
750 debugging code is not needed
751 * fixed EAPOL-Key validation to drop packets with invalid Key Data
752 Length; such frames could have crashed wpa_supplicant due to buffer
754 * added support for wired authentication (IEEE 802.1X on wired
755 Ethernet); driver interface 'wired'
756 * obsoleted set_wpa() handler in the driver interface API (it can be
757 replaced by moving enable/disable functionality into init()/deinit())
758 (calls to set_wpa() are still present for backwards compatibility,
759 but they may be removed in the future)
760 * driver_madwifi: fixed association in plaintext mode
761 * modified the EAP workaround that accepts EAP-Success with incorrect
762 Identifier to be even less strict about verification in order to
763 interoperate with some authentication servers
764 * added support for sending TLS alerts
765 * added support for 'any' SSID wildcard; if ssid is not configured or
766 is set to an empty string, any SSID will be accepted for non-WPA AP
767 * added support for asking PIN (for SIM) from frontends (e.g.,
768 wpa_cli); if a PIN is needed, but not included in the configuration
769 file, a control interface request is sent and EAP processing is
770 delayed until the PIN is available
771 * added support for using external devices (e.g., a smartcard) for
772 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
773 new wpa_supplicant.conf variables:
774 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
775 - network: engine, engine_id, key_id
776 * added experimental support for EAP-PAX
777 * added monitor mode for wpa_cli (-a<path to a program to run>) that
778 allows external commands (e.g., shell scripts) to be run based on
779 wpa_supplicant events, e.g., when authentication has been completed
780 and data connection is ready; other related wpa_cli arguments:
781 -B (run in background), -P (write PID file); wpa_supplicant has a new
782 command line argument (-W) that can be used to make it wait until a
783 control interface command is received in order to avoid missing
785 * added support for opportunistic WPA2 PMKSA key caching (disabled by
786 default, can be enabled with proactive_key_caching=1)
787 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
788 Authenticator rejects PMKSA caching attempt and the driver is not
789 using assoc_info events
790 * added -P<pid file> argument for wpa_supplicant to write the current
791 process id into a file
793 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
794 * added new phase1 option parameter, include_tls_length=1, to force
795 wpa_supplicant to add TLS Message Length field to all TLS messages
796 even if the packet is not fragmented; this may be needed with some
797 authentication servers
798 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
799 using drivers that take care of AP selection (e.g., when using
801 * fixed reprocessing of pending request after ctrl_iface requests for
802 identity/password/otp
803 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
804 EAP-PEAP and EAP-TTLS
805 * all drivers using driver_wext: set interface up and select Managed
806 mode when starting wpa_supplicant; set interface down when exiting
807 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
808 ipw2100 and ipw2200; please note that this also changed the
809 configuration variable in .config to CONFIG_DRIVER_IPW
812 * fixed a busy loop introduced in v0.3.5 for scan result processing
813 when no matching AP is found
816 * added a workaround for an interoperability issue with a Cisco AP
818 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
819 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
820 retransmission of dropped frames)
821 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
822 (e.g., segfault when processing EAPOL-Key frames)
823 * fixed EAP workaround and fast reauthentication configuration for
824 RSN pre-authentication; previously these were disabled and
825 pre-authentication would fail if the used authentication server
826 requires EAP workarounds
827 * added support for blacklisting APs that fail or timeout
828 authentication in ap_scan=1 mode so that all APs are tried in cases
829 where the ones with strongest signal level are failing authentication
830 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
831 authentication attempt
832 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
833 in the previous authentication (previously, only Phase 1 success was
837 * added preliminary support for IBSS (ad-hoc) mode configuration
838 (mode=1 in network block); this included a new key_mgmt mode
839 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
840 key management; see wpa_supplicant.conf for more details and an
841 example on how to configure this (note: this is currently implemented
842 only for driver_hostapd.c, but the changes should be trivial to add
843 in associate() handler for other drivers, too (assuming the driver
845 * added preliminary port for native Windows (i.e., no cygwin) using
849 * added optional support for GNU Readline and History Libraries for
850 wpa_cli (CONFIG_READLINE)
851 * cleaned up EAP state machine <-> method interface and number of
852 small problems with error case processing not terminating on
853 EAP-Failure but waiting for timeout
854 * added couple of workarounds for interoperability issues with a
855 Cisco AP when using WPA2
856 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
857 Note: This requires a patch for openssl to add support for TLS
858 extensions and number of workarounds for operations without
859 certificates. Proof of concept type of experimental patch is
860 included in openssl-tls-extensions.patch.
863 * fixed private key loading for cases where passphrase is not set
864 * fixed Windows/cygwin L2 packet handler freeing; previous version
865 could cause a segfault when RSN pre-authentication was completed
866 * added support for PMKSA caching with drivers that generate RSN IEs
867 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
868 but similar code can be easily added to driver_ndiswrapper.c once
869 ndiswrapper gets full support for RSN PMKSA caching
870 * improved recovery from PMKID mismatches by requesting full EAP
871 authentication in case of failed PMKSA caching attempt
872 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
873 (this requires that ndis_events is ran while wpa_supplicant is
875 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
876 * added support for driver interfaces to replace the interface name
877 based on driver/OS specific mapping, e.g., in case of driver_ndis,
878 this allows the beginning of the adapter description to be used as
880 * added support for CR+LF (Windows-style) line ends in configuration
882 * driver_ndis: enable radio before starting scanning, disable radio
884 * modified association event handler to set portEnabled = FALSE before
885 clearing port Valid in order to reset EAP state machine and avoid
886 problems with new authentication getting ignored because of state
887 machines ending up in AUTHENTICATED/SUCCESS state based on old
889 * added support for driver events to add PMKID candidates in order to
890 allow drivers to give priority to most likely roaming candidates
891 * driver_hostap: moved PrivacyInvoked configuration to associate()
892 function so that this will not be set for plaintext connections
893 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
894 interface can distinguish plaintext and IEEE 802.1X (no WPA)
896 * fixed static WEP key configuration to use broadcast/default type for
897 all keys (previously, the default TX key was configured as pairwise/
899 * driver_ndis: added legacy WPA capability detection for non-WPA2
901 * added support for setting static WEP keys for IEEE 802.1X without
902 dynamic WEP keying (eapol_flags=0)
905 * added support for reading PKCS#12 (PFX) files (as a replacement for
906 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
907 * fixed compilation with CONFIG_PCSC=y
908 * added new ap_scan mode, ap_scan=2, for drivers that take care of
909 association, but need to be configured with security policy and SSID,
910 e.g., ndiswrapper and NDIS driver; this mode should allow such
911 drivers to work with hidden SSIDs and optimized roaming; when
912 ap_scan=2 is used, only the first network block in the configuration
913 file is used and this configuration should have explicit security
914 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
915 group, proto variables
916 * added experimental port of wpa_supplicant for Windows
917 - driver_ndis.c driver interface (NDIS OIDs)
918 - currently, this requires cygwin and WinPcap
919 - small utility, win_if_list, can be used to get interface name
920 * control interface can now be removed at build time; add
921 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
922 * optional Xsupplicant interface can now be removed at build time;
923 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
924 * added auth_alg to driver interface associate() parameters to make it
925 easier for drivers to configure authentication algorithm as part of
928 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
929 * driver_broadcom: added new driver interface for Broadcom wl.o driver
930 (a generic driver for Broadcom IEEE 802.11a/g cards)
931 * wpa_cli: fixed parsing of -p <path> command line argument
932 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
933 ACK, not tunneled EAP-Success (of which only the first byte was
934 actually send due to a bug in previous code); this seems to
935 interoperate with most RADIUS servers that implements PEAPv1
936 * PEAPv1: added support for terminating PEAP authentication on tunneled
937 EAP-Success message; this can be configured by adding
938 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
939 (some RADIUS servers require this whereas others require a tunneled
941 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
942 the old label for key derivation; previously, the default was 1,
943 but it looks like most existing PEAPv1 implementations use the old
944 label which is thus more suitable default option
945 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
946 * fixed parsing of wep_tx_keyidx
947 * added support for configuring list of allowed Phase 2 EAP types
948 (for both EAP-PEAP and EAP-TTLS) instead of only one type
949 * added support for configuring IEEE 802.11 authentication algorithm
950 (auth_alg; mainly for using Shared Key authentication with static
952 * added support for EAP-AKA (with UMTS SIM)
953 * fixed couple of errors in PCSC handling that could have caused
954 random-looking errors for EAP-SIM
955 * added support for EAP-SIM pseudonyms and fast re-authentication
956 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
958 * added support for EAP-SIM with two challanges
959 (phase1="sim_min_num_chal=3" can be used to require three challenges)
960 * added support for configuring DH/DSA parameters for an ephemeral DH
961 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
962 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
963 and optional DH key exchange to achieve forward secracy with RSA keys
964 * added support for matching subject of the authentication server
965 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
966 configuration variables subject_match and subject_match2
967 * changed SSID configuration in driver_wext.c (used by many driver
968 interfaces) to use ssid_len+1 as the length for SSID since some Linux
970 * fixed couple of unaligned reads in scan result parsing to fix WPA
971 connection on some platforms (e.g., ARM)
972 * added driver interface for Intel ipw2100 driver
973 * added support for LEAP with WPA
974 * added support for larger scan results report (old limit was 4 kB of
975 data, i.e., about 35 or so APs) when using Linux wireless extensions
977 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
978 only if there is a PMKSA cache entry for the current AP
979 * fixed error handling for case where reading of scan results fails:
980 must schedule a new scan or wpa_supplicant will remain waiting
982 * changed debug output to remove shared password/key material by
983 default; all key information can be included with -K command line
984 argument to match the previous behavior
985 * added support for timestamping debug log messages (disabled by
986 default, can be enabled with -t command line argument)
987 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
988 if keys are not configured to be used; this fixes IEEE 802.1X mode
989 with drivers that use this information to configure whether Privacy
990 bit can be in Beacon frames (e.g., ndiswrapper)
991 * avoid clearing driver keys if no keys have been configured since last
992 key clear request; this seems to improve reliability of group key
993 handshake for ndiswrapper & NDIS driver which seems to be suffering
994 of some kind of timing issue when the keys are cleared again after
996 * changed driver interface API:
997 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
998 version is being used (now, this is set to 2; previously, it was
1000 - pass pointer to private data structure to all calls
1001 - the new API is not backwards compatible; all in-tree driver
1002 interfaces has been converted to the new API
1003 * added support for controlling multiple interfaces (radios) per
1004 wpa_supplicant process; each interface needs to be listed on the
1005 command line (-c, -i, -D arguments) with -N as a separator
1006 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
1007 * added a workaround for EAP servers that incorrectly use same Id for
1008 sequential EAP packets
1009 * changed libpcap/libdnet configuration to use .config variable,
1010 CONFIG_DNET_PCAP, instead of requiring Makefile modification
1011 * improved downgrade attack detection in IE verification of msg 3/4:
1012 verify both WPA and RSN IEs, if present, not only the selected one;
1013 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
1014 Probe Response frame, and RSN is enabled in wpa_supplicant
1016 * fixed WPA msg 3/4 processing to allow Key Data field contain other
1017 IEs than just one WPA IE
1018 * added support for FreeBSD and driver interface for the BSD net80211
1019 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
1020 required kernel mods have not yet been committed
1021 * made EAP workarounds configurable; enabled by default, can be
1022 disabled with network block option eap_workaround=0
1024 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
1025 * resolved couple of interoperability issues with EAP-PEAPv1 and
1026 Phase 2 (inner EAP) fragment reassembly
1027 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
1028 AP is using non-zero key index for the unicast key and key index zero
1029 for the broadcast key
1030 * driver_hostap: fixed IEEE 802.1X WEP key updates and
1031 re-authentication by allowing unencrypted EAPOL frames when not using
1033 * added a new driver interface, 'wext', which uses only standard,
1034 driver independent functionality in Linux wireless extensions;
1035 currently, this can be used only for non-WPA IEEE 802.1X mode, but
1036 eventually, this is to be extended to support full WPA/WPA2 once
1037 Linux wireless extensions get support for this
1038 * added support for mode in which the driver is responsible for AP
1039 scanning and selection; this is disabled by default and can be
1040 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
1041 this mode can be used, e.g., with generic 'wext' driver interface to
1042 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
1043 supporting wireless extensions.
1044 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
1045 operation with an AP that does not include SSID in the Beacon frames)
1046 * added support for new EAP authentication methods:
1047 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
1048 * added support for asking one-time-passwords from frontends (e.g.,
1049 wpa_cli); this 'otp' command works otherwise like 'password' command,
1050 but the password is used only once and the frontend will be asked for
1051 a new password whenever a request from authenticator requires a
1052 password; this can be used with both EAP-OTP and EAP-GTC
1053 * changed wpa_cli to automatically re-establish connection so that it
1054 does not need to be re-started when wpa_supplicant is terminated and
1056 * improved user data (identity/password/otp) requests through
1057 frontends: process pending EAPOL packets after getting new
1058 information so that full authentication does not need to be
1059 restarted; in addition, send pending requests again whenever a new
1060 frontend is attached
1061 * changed control frontends to use a new directory for socket files to
1062 make it easier for wpa_cli to automatically select between interfaces
1063 and to provide access control for the control interface;
1064 wpa_supplicant.conf: ctrl_interface is now a path
1065 (/var/run/wpa_supplicant is the recommended path) and
1066 ctrl_interface_group can be used to select which group gets access to
1067 the control interface;
1068 wpa_cli: by default, try to connect to the first interface available
1069 in /var/run/wpa_supplicant; this path can be overriden with -p option
1070 and an interface can be selected with -i option (i.e., in most common
1071 cases, wpa_cli does not need to get any arguments)
1072 * added support for LEAP
1073 * added driver interface for Linux ndiswrapper
1074 * added priority option for network blocks in the configuration file;
1075 this allows networks to be grouped based on priority (the scan
1076 results are searched for matches with network blocks in this order)
1079 * sort scan results to improve AP selection
1080 * fixed control interface socket removal for some error cases
1081 * improved scan requesting and authentication timeout
1082 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1084 * PEAP version can now be forced with phase1="peapver=<ver>"
1085 (mostly for testing; by default, the highest version supported by
1086 both the Supplicant and Authentication Server is selected
1088 * added support for madwifi driver (Atheros ar521x)
1089 * added a workaround for cases where AP sets Install Tx/Rx bit for
1090 WPA Group Key messages when pairwise keys are used (without this,
1091 the Group Key would be used for Tx and the AP would drop frames
1093 * added GSM SIM/USIM interface for GSM authentication algorithm for
1094 EAP-SIM; this requires pcsc-lite
1095 * added support for ATMEL AT76C5XXx driver
1096 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1097 does not include key data in the EAPOL-Key frame (i.e., part of
1098 EAP keying material is used as data encryption key)
1099 * added support for using plaintext and static WEP networks
1103 * added support for new EAP authentication methods:
1104 EAP-TTLS/EAP-MD5-Challenge
1106 EAP-TTLS/EAP-MSCHAPv2
1114 EAP-PEAP/MD5-Challenge
1116 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1117 * added support for anonymous identity (to be used when identity is
1118 sent in plaintext; real identity will be used within TLS protected
1119 tunnel (e.g., with EAP-TTLS)
1120 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1121 * added support for requesting identity and password information using
1122 control interface; in other words, the password for EAP-PEAP or
1123 EAP-TTLS does not need to be included in the configuration file since
1124 a frontand (e.g., wpa_cli) can ask it from the user
1125 * improved RSN pre-authentication to use a candidate list and process
1126 all candidates from each scan; not only one per scan
1127 * fixed RSN IE and WPA IE capabilities field parsing
1128 * ignore Tx bit in GTK IE when Pairwise keys are used
1129 * avoid making new scan requests during IEEE 802.1X negotiation
1130 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1131 with TLS support (this replaces the included implementation with
1132 library code to save about 8 kB since the library code is needed
1134 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1135 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1138 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1140 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1141 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1142 - EAP-MD5 (cannot be used with WPA-RADIUS)
1143 [draft-ietf-eap-rfc2284bis-09.txt]
1144 - EAP-TLS [RFC 2716]
1145 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1146 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1147 [draft-kamath-pppext-eap-mschapv2-00.txt]
1148 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1149 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1150 - new configuration file options: eap, identity, password, ca_cert,
1151 client_cert, privatekey, private_key_passwd
1152 - Xsupplicant is not required anymore, but it can be used by
1153 disabling the internal IEEE 802.1X Supplicant with -e command line
1155 - this code is not included in the default build; Makefile need to
1156 be edited for this (uncomment lines for selected functionality)
1157 - EAP-TLS and EAP-PEAP require openssl libraries
1158 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1159 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1160 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1161 EAPOL-Key frames instead of WPA key handshakes)
1162 * added support for IEEE 802.11i/RSN (WPA2)
1163 - improved PTK Key Handshake
1164 - PMKSA caching, pre-authentication
1165 * fixed wpa_supplicant to ignore possible extra data after WPA
1166 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1167 TPTK' error from message 3 of 4-Way Handshake in case the AP
1168 includes extra data after the EAPOL-Key)
1169 * added interface for external programs (frontends) to control
1171 - CLI example (wpa_cli) with interactive mode and command line
1173 - replaced SIGUSR1 status/statistics with the new control interface
1174 * made some feature compile time configurable
1175 - .config file for make
1176 - driver interfaces (hostap, hermes, ..)
1177 - EAPOL/EAP functions
1180 * Initial version of wpa_supplicant
