1 ChangeLog for wpa_supplicant
4 * added support for Wi-Fi Protected Setup (WPS)
5 (wpa_supplicant can now be configured to act as a WPS Enrollee to
6 enroll credentials for a network using PIN and PBC methods; in
7 addition, wpa_supplicant can act as a wireless WPS Registrar to
8 configure an AP); WPS support can be enabled by adding CONFIG_WPS=y
9 into .config and setting the runtime configuration variables in
10 wpa_supplicant.conf (see WPS section in the example configuration
11 file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to
12 manage WPS negotiation; see README-WPS for more details
13 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
14 * added support for using driver_test over UDP socket
15 * fixed PEAPv0 Cryptobinding interoperability issue with Windows Server
16 2008 NPS; optional cryptobinding is now enabled (again) by default
17 * fixed PSK editing in wpa_gui
18 * changed EAP-GPSK to use the IANA assigned EAP method type 51
19 * added a Windows installer that includes WinPcap and all the needed
20 DLLs; in addition, it set up the registry automatically so that user
21 will only need start wpa_gui to get prompted to start the wpasvc
22 servide and add a new interface if needed through wpa_gui dialog
23 * updated management frame protection to use IEEE 802.11w/D7.0
26 * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
27 (can be used to simulate test SIM/USIM card with a known private key;
28 enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
29 and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
30 * added a new network configuration option, wpa_ptk_rekey, that can be
31 used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
32 against TKIP deficiencies
33 * added an optional mitigation mechanism for certain attacks against
34 TKIP by delaying Michael MIC error reports by a random amount of time
35 between 0 and 60 seconds; this can be enabled with a build option
36 CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
37 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
39 * updated OpenSSL code for EAP-FAST to use an updated version of the
40 session ticket overriding API that was included into the upstream
41 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
42 needed with that version anymore)
43 * updated userspace MLME instructions to match with the current Linux
44 mac80211 implementation; please also note that this can only be used
45 with driver_nl80211.c (the old code from driver_wext.c was removed)
46 * added support (Linux only) for RoboSwitch chipsets (often found in
47 consumer grade routers); driver interface 'roboswitch'
48 * fixed canceling of PMKSA caching when using drivers that generate
49 RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
53 * added support for SHA-256 as X.509 certificate digest when using the
54 internal X.509/TLSv1 implementation
55 * updated management frame protection to use IEEE 802.11w/D6.0
56 * added support for using SHA256-based stronger key derivation for WPA2
58 * fixed FT (IEEE 802.11r) authentication after a failed association to
60 * added support for configuring Phase 2 (inner/tunneled) authentication
61 method with wpa_gui-qt4
64 * added support for EAP Sequences in EAP-FAST Phase 2
65 * added support for using TNC with EAP-FAST
66 * added driver_ps3 for the PS3 Linux wireless driver
67 * added support for optional cryptobinding with PEAPv0
68 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
69 allow fallback to full handshake if server rejects PAC-Opaque
70 * added fragmentation support for EAP-TNC
71 * added support for parsing PKCS #8 formatted private keys into the
72 internal TLS implementation (both PKCS #1 RSA key and PKCS #8
73 encapsulated RSA key can now be used)
74 * added option of using faster, but larger, routines in the internal
75 LibTomMath (for internal TLS implementation) to speed up DH and RSA
76 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
77 * fixed race condition between disassociation event and group key
78 handshake to avoid getting stuck in incorrect state [Bug 261]
79 * fixed opportunistic key caching (proactive_key_caching)
82 * removed 'nai' and 'eappsk' network configuration variables that were
83 previously used for configuring user identity and key for EAP-PSK,
84 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
85 replacement for 'nai' (if old configuration used a separate
86 'identity' value, that would now be configured as
87 'anonymous_identity'). 'password' field is now used as the
88 replacement for 'eappsk' (it can also be set using hexstring to
89 present random binary data)
90 * removed '-w' command line parameter (wait for interface to be added,
91 if needed); cleaner way of handling this functionality is to use an
92 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
93 when an interface is added
94 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
95 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
96 indicating when new scan results become available
97 * added new ctrl_iface command, BSS, to allow scan results to be
98 fetched without hitting the message size limits (this command
99 can be used to iterate through the scan results one BSS at the time)
100 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
101 attributes in EAP-SIM Start/Response when using fast reauthentication
102 * fixed EAPOL not to end up in infinite loop when processing dynamic
103 WEP keys with IEEE 802.1X
104 * fixed problems in getting NDIS events from WMI on Windows 2000
107 * added support for Makefile builds to include debug-log-to-a-file
108 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
109 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
110 lengths properly to avoid potential crash caused by invalid messages
111 * added data structure for storing allocated buffers (struct wpabuf);
112 this does not affect wpa_supplicant usage, but many of the APIs
113 changed and various interfaces (e.g., EAP) is not compatible with old
115 * added support for protecting EAP-AKA/Identity messages with
116 AT_CHECKCODE (optional feature in RFC 4187)
117 * added support for protected result indication with AT_RESULT_IND for
118 EAP-SIM and EAP-AKA (phase1="result_ind=1")
119 * added driver_wext workaround for race condition between scanning and
120 association with drivers that take very long time to scan all
121 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
122 using a longer hardcoded timeout for the scan if the driver supports
123 notifications for scan completion (SIOCGIWSCAN event); this helps,
124 e.g., in cases where wpa_supplicant and madwifi driver ended up in
125 loop where the driver did not even try to associate
126 * stop EAPOL timer tick when no timers are in use in order to reduce
127 power consumption (no need to wake up the process once per second)
129 * added support for privilege separation (run only minimal part of
130 wpa_supplicant functionality as root and rest as unprivileged,
131 non-root process); see 'Privilege separation' in README for details;
132 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
134 * changed scan results data structure to include all information
135 elements to make it easier to support new IEs; old get_scan_result()
136 driver_ops is still supported for backwards compatibility (results
137 are converted internally to the new format), but all drivers should
138 start using the new get_scan_results2() to make them more likely to
139 work with new features
140 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
141 application, i.e., it does not require Qt3Support anymore; Windows
142 binary of wpa_gui.exe is now from this directory and only requires
143 QtCore4.dll and QtGui4.dll libraries
144 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
145 available as a separate package to make wpa_gui installation easier:
146 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
147 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
148 only shared key/password authentication is supported in this version
151 * added support for configuring password as NtPasswordHash
152 (16-byte MD4 hash of password) in hash:<32 hex digits> format
153 * added support for fallback from abbreviated TLS handshake to
154 full handshake when using EAP-FAST (e.g., due to an expired
156 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
157 draft (draft-ietf-emu-eap-gpsk-07.txt)
158 * added support for drivers that take care of RSN 4-way handshake
159 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
160 WPA_ALG_PMK in set_key)
161 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
162 .config); this version supports only ap_scan=2 mode and allow the
163 driver to take care of the 4-way handshake
164 * fixed a buffer overflow in parsing TSF from scan results when using
165 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
167 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
168 * fixed an integer overflow issue in the ASN.1 parser used by the
169 (experimental) internal TLS implementation to avoid a potential
171 * fixed a race condition with -W option (wait for a control interface
172 monitor before starting) that could have caused the first messages to
174 * added support for processing TNCC-TNCS-Messages to report
175 recommendation (allow/none/isolate) when using TNC [Bug 243]
178 * added network configuration parameter 'frequency' for setting
179 initial channel for IBSS (adhoc) networks
180 * added experimental IEEE 802.11r/D6.0 support
181 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
182 * updated EAP-PSK to use the IANA-allocated EAP type 47
183 * fixed EAP-PAX key derivation
184 * fixed EAP-PSK bit ordering of the Flags field
185 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
186 tunnelled identity request (previously, the identifier from the outer
187 method was used, not the tunnelled identifier which could be
189 * added support for fragmentation of outer TLS packets during Phase 2
190 of EAP-PEAP/TTLS/FAST
191 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
192 * added support for EAP-FAST authentication with inner methods that
193 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
194 for PAC provisioning)
195 * added support for authenticated EAP-FAST provisioning
196 * added support for configuring maximum number of EAP-FAST PACs to
197 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
198 * added support for storing EAP-FAST PACs in binary format
199 (fast_pac_format=binary in phase1 string)
200 * fixed dbus ctrl_iface to validate message interface before
201 dispatching to avoid a possible segfault [Bug 190]
202 * fixed PeerKey key derivation to use the correct PRF label
203 * updated Windows binary build to link against OpenSSL 0.9.8d and
204 added support for EAP-FAST
205 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
206 draft (draft-ietf-emu-eap-gpsk-04.txt)
207 * fixed EAP-AKA Notification processing to allow Notification to be
208 processed after AKA Challenge response has been sent
209 * updated to use IEEE 802.11w/D2.0 for management frame protection
211 * fixed EAP-TTLS implementation not to crash on use of freed memory
212 if TLS library initialization fails
213 * added support for EAP-TNC (Trusted Network Connect)
214 (this version implements the EAP-TNC method and EAP-TTLS changes
215 needed to run two methods in sequence (IF-T) and the IF-IMC and
216 IF-TNCCS interfaces from TNCC)
219 * added experimental, integrated TLSv1 client implementation with the
220 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
221 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
222 .config); this can be useful, e.g., if the target system does not
223 have a suitable TLS library and a minimal code size is required
224 (total size of this internal TLS/crypto code is bit under 50 kB on
225 x86 and the crypto code is shared by rest of the supplicant so some
226 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
227 * removed STAKey handshake since PeerKey handshake has replaced it in
228 IEEE 802.11ma and there are no known deployments of STAKey
229 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
230 draft (draft-ietf-emu-eap-gpsk-01.txt)
231 * added preliminary implementation of IEEE 802.11w/D1.0 (management
233 (Note: this requires driver support to work properly.)
234 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
235 * fixed Windows named pipes ctrl_iface to not stop listening for
236 commands if client program opens a named pipe and closes it
237 immediately without sending a command
238 * fixed USIM PIN status determination for the case that PIN is not
239 needed (this allows EAP-AKA to be used with USIM cards that do not
241 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
242 be used with cards that do not support file selection based on
244 * added support for matching the subjectAltName of the authentication
245 server certificate against multiple name components (e.g.,
246 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
247 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
248 affects IEEE 802.1X with dynamic WEP keys)
249 * changed ctrl_iface network configuration 'get' operations to not
250 return password/key material; if these fields are requested, "*"
251 will be returned if the password/key is set, but the value of the
252 parameter is not exposed
255 * added support for building Windows version with UNICODE defined
256 (wide-char functions)
257 * driver_ndis: fixed static WEP configuration to avoid race condition
258 issues with some NDIS drivers between association and setting WEP
260 * driver_ndis: added validation for IELength value in scan results to
261 avoid crashes when using buggy NDIS drivers [Bug 165]
262 * fixed Release|Win32 target in the Visual Studio project files
263 (previously, only Debug|Win32 target was set properly)
264 * changed control interface API call wpa_ctrl_pending() to allow it to
265 return -1 on error (e.g., connection lost); control interface clients
266 will need to make sure that they verify that the value is indeed >0
267 when determining whether there are pending messages
268 * added an alternative control interface backend for Windows targets:
269 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
270 control interface mechanism for Windows builds (previously, UDP to
272 * changed ctrl_interface configuration for UNIX domain sockets:
273 - deprecated ctrl_interface_group variable (it may be removed in
275 - allow both directory and group be configured with ctrl_interface
276 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
277 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
278 case when group is not changed
279 * added support for controlling more than one interface per process in
281 * added a workaround for a case where the AP is using unknown address
282 (e.g., MAC address of the wired interface) as the source address for
283 EAPOL-Key frames; previously, that source address was used as the
284 destination for EAPOL-Key frames and in key derivation; now, BSSID is
285 used even if the source address does not match with it
286 (this resolves an interoperability issue with Thomson SpeedTouch 580)
287 * added a workaround for UDP-based control interface (which was used in
288 Windows builds before this release) to prevent packets with forged
289 addresses from being accepted as local control requests
290 * removed ndis_events.cpp and possibility of using external
291 ndis_events.exe; C version (ndis_events.c) is fully functional and
292 there is no desire to maintain two separate versions of this
294 * ndis_events: Changed NDIS event notification design to use WMI to
295 learn the adapter description through Win32_PnPEntity class; this
296 should fix some cases where the adapter name was not recognized
297 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
299 * fixed selection of the first network in ap_scan=2 mode; previously,
300 wpa_supplicant could get stuck in SCANNING state when only the first
301 network for enabled (e.g., after 'wpa_cli select_network 0')
302 * winsvc: added support for configuring ctrl_interface parameters in
303 registry (ctrl_interface string value in
304 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
305 required to enable control interface (previously, this was hardcoded
307 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
308 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
311 * fixed build with CONFIG_STAKEY=y [Bug 143]
312 * added support for doing MLME (IEEE 802.11 management frame
313 processing) in wpa_supplicant when using Devicescape IEEE 802.11
314 stack (wireless-dev.git tree)
315 * added a new network block configuration option, fragment_size, to
316 configure the maximum EAP fragment size
317 * driver_ndis: Disable WZC automatically for the selected interface to
318 avoid conflicts with two programs trying to control the radio; WZC
319 will be re-enabled (if it was enabled originally) when wpa_supplicant
321 * added an experimental TLSv1 client implementation
322 (CONFIG_TLS=internal) that can be used instead of an external TLS
323 library, e.g., to reduce total size requirement on systems that do
324 not include any TLS library by default (this is not yet complete;
325 basic functionality is there, but certificate validation is not yet
327 * added PeerKey handshake implementation for IEEE 802.11e
328 direct link setup (DLS) to replace STAKey handshake
329 * fixed WPA PSK update through ctrl_iface for the case where the old
330 PSK was derived from an ASCII passphrase and the new PSK is set as
331 a raw PSK (hex string)
332 * added new configuration option for identifying which network block
333 was used (id_str in wpa_supplicant.conf; included on
334 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
335 variable in wpa_cli action scripts; in addition WPA_ID variable is
336 set to the current unique identifier that wpa_supplicant assigned
337 automatically for the network and that can be used with
338 GET_NETWORK/SET_NETWORK ctrl_iface commands)
339 * wpa_cli action script is now called only when the connect/disconnect
340 status changes or when associating with a different network
341 * fixed configuration parser not to remove CCMP from group cipher list
342 if WPA-None (adhoc) is used (pairwise=NONE in that case)
343 * fixed integrated NDIS events processing not to hang the process due
344 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
345 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
346 draft-clancy-emu-eap-shared-secret-00.txt)
347 * added Microsoft Visual Studio 2005 solution and project files for
348 build wpa_supplicant for Windows (see vs2005 subdirectory)
349 * eloop_win: fixed unregistration of Windows events
350 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
351 at the end of RSN pre-authentication and added unregistration of
352 a Windows event to avoid getting eloop_win stuck with an invalid
354 * driver_ndis: added support for selecting AP based on BSSID
355 * added new environmental variable for wpa_cli action scripts:
356 WPA_CTRL_DIR is the current control interface directory
357 * driver_ndis: added support for using NDISUIO instead of WinPcap for
358 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
359 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
360 wpa_supplicant without requiring WinPcap; note that using NDISUIO
361 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
362 only one application to open the device
363 * changed NDIS driver naming to only include device GUID, e.g.,
364 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
365 specific \Device\NPF_ prefix before the GUID; the prefix is still
366 allowed for backwards compatibility, but it is not required anymore
367 when specifying the interface
368 * driver_ndis: re-initialize driver interface is the adapter is removed
369 and re-inserted [Bug 159]
370 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
371 big endian hosts [Bug 146]
374 * fixed EAP-GTC response to include correct user identity when run as
375 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
376 * driver_ndis: Fixed encryption mode configuration for unencrypted
377 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
378 refused to associate with open networks) [Bug 106]
379 * driver_ndis: use BSSID OID polling to detect when IBSS network is
380 formed even when ndis_events code is included since some NDIS drivers
381 do not generate media connect events in IBSS mode
382 * config_winreg: allow global ctrl_interface parameter to be configured
384 * config_winreg: added support for saving configuration data into
386 * added support for controlling network device operational state
387 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
388 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
389 that can use this information)
390 * driver_wext: added support for WE-21 change to SSID configuration
391 * driver_wext: fixed privacy configuration for static WEP keys mode
393 * added an optional driver_ops callback for MLME-SETPROTECTION.request
395 * added support for EAP-SAKE (no EAP method number allocated yet, so
396 this is using the same experimental type 255 as EAP-PSK)
397 * added support for dynamically loading EAP methods (.so files) instead
398 of requiring them to be statically linked in; this is disabled by
399 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
403 * do not try to use USIM APDUs when initializing PC/SC for SIM card
404 access for a network that has not enabled EAP-AKA
405 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
406 v0.5.1 due to the new support for expanded EAP types)
407 * added support for generating EAP Expanded Nak
408 * try to fetch scan results once before requesting new scan when
409 starting up in ap_scan=1 mode (this can speed up initial association
410 a lot with, e.g., madwifi-ng driver)
411 * added support for receiving EAPOL frames from a Linux bridge
412 interface (-bbr0 on command line)
413 * fixed EAPOL re-authentication for sessions that used PMKSA caching
414 * changed EAP method registration to use a dynamic list of methods
415 instead of a static list generated at build time
416 * fixed PMKSA cache deinitialization not to use freed memory when
417 removing PMKSA entries
418 * fixed a memory leak in EAP-TTLS re-authentication
419 * reject WPA/WPA2 message 3/4 if it does not include any valid
421 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
422 if the driver does not support SIOCSIWAUTH
425 * driver_test: added better support for multiple APs and STAs by using
426 a directory with sockets that include MAC address for each device in
427 the name (driver_param=test_dir=/tmp/test)
428 * added support for EAP expanded type (vendor specific EAP methods)
429 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
430 option can be changed if needed
431 * wpa_cli/wpa_gui: skip non-socket files in control directory when
432 using UNIX domain sockets; this avoids selecting an incorrect
433 interface (e.g., a PID file could be in this directory, even though
434 use of this directory for something else than socket files is not
436 * fixed TLS library deinitialization after RSN pre-authentication not
437 to disable TLS library for normal authentication
438 * driver_wext: Remove null-termination from SSID length if the driver
439 used it; some Linux drivers do this and they were causing problems in
440 wpa_supplicant not finding matching configuration block. This change
441 would break a case where the SSID actually ends in '\0', but that is
442 not likely to happen in real use.
443 * fixed PMKSA cache processing not to trigger deauthentication if the
444 current PMKSA cache entry is replaced with a valid new entry
445 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
446 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
449 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
450 * added experimental STAKey handshake implementation for IEEE 802.11e
451 direct link setup (DLS); note: this is disabled by default in both
452 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
454 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
455 decrypt AT_ENCR_DATA attributes correctly
456 * fixed EAP-AKA to allow resynchronization within the same session
457 * made code closer to ANSI C89 standard to make it easier to port to
458 other C libraries and compilers
459 * started moving operating system or C library specific functions into
460 wrapper functions defined in os.h and implemented in os_*.c to make
462 * wpa_supplicant can now be built with Microsoft Visual C++
463 (e.g., with the freely available Toolkit 2003 version or Visual
464 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
465 example makefile for nmake
466 * added support for using Windows registry for command line parameters
467 (CONFIG_MAIN=main_winsvc) and configuration data
468 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
469 contents; this version can be run both as a Windows service and as a
470 normal application; 'wpasvc.exe app' to start as applicant,
471 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
472 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
474 * made it possible to link ndis_events.exe functionality into
475 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
476 * added better support for multiple control interface backends
477 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
478 * fixed PC/SC code to use correct length for GSM AUTH command buffer
479 and to not use pioRecvPci with SCardTransmit() calls; these were not
480 causing visible problems with pcsc-lite, but Windows Winscard.dll
481 refused the previously used parameters; this fixes EAP-SIM and
482 EAP-AKA authentication using SIM/USIM card under Windows
483 * added new event loop implementation for Windows using
484 WaitForMultipleObject() instead of select() in order to allow waiting
485 for non-socket objects; this can be selected with
486 CONFIG_ELOOP=eloop_win in .config
487 * added support for selecting l2_packet implementation in .config
488 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
489 winpcap, freebsd, none)
490 * added new l2_packet implementation for WinPcap
491 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
492 reduce latency in EAPOL receive processing from about 100 ms to about
494 * added support for EAP-FAST key derivation using other ciphers than
495 RC4-128-SHA for authentication and AES128-SHA for provisioning
496 * added support for configuring CA certificate as DER file and as a
498 * fixed private key configuration as configuration blob and added
499 support for using PKCS#12 as a blob
500 * tls_gnutls: added support for using PKCS#12 files; added support for
502 * added support for loading trusted CA certificates from Windows
503 certificate store: ca_cert="cert_store://<name>", where <name> is
504 likely CA (Intermediate CA certificates) or ROOT (root certificates)
505 * added C version of ndis_events.cpp and made it possible to build this
506 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
507 easily on cross-compilation builds
508 * added wpasvc.exe into Windows binary release; this is an alternative
509 version of wpa_supplicant.exe with configuration backend using
510 Windows registry and with the entry point designed to run as a
512 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
513 wpasvc.exe and removed this additional tool from the Windows binary
514 release since it is not needed anymore
515 * load winscard.dll functions dynamically when building with MinGW
516 since MinGW does not yet include winscard library
518 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
519 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
520 and WinPcap to receive frames sent to PAE group address
521 * disable EAP state machine when IEEE 802.1X authentication is not used
522 in order to get rid of bogus "EAP failed" messages
523 * fixed OpenSSL error reporting to go through all pending errors to
524 avoid confusing reports of old errors being reported at later point
526 * fixed configuration file updating to not write empty variables
527 (e.g., proto or key_mgmt) that the file parser would not accept
528 * fixed ADD_NETWORK ctrl_iface command to use the same default values
529 for variables as empty network definitions read from config file
531 * fixed EAP state machine to not discard EAP-Failure messages in many
532 cases (e.g., during TLS handshake)
533 * fixed a infinite loop in private key reading if the configured file
534 cannot be parsed successfully
535 * driver_madwifi: added support for madwifi-ng
536 * wpa_gui: do not display password/PSK field contents
537 * wpa_gui: added CA certificate configuration
538 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
539 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
540 the new AP is using different WPA/RSN IE
541 * use longer timeout for IEEE 802.11 association to avoid problems with
542 drivers that may take more than five second to associate
545 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
546 RSN IE, but WPA IE would match with wpa_supplicant configuration
547 * added support for named configuration blobs in order to avoid having
548 to use file system for external files (e.g., certificates);
549 variables can be set to "blob://<blob name>" instead of file path to
550 use a named blob; supported fields: pac_file, client_cert,
552 * fixed RSN pre-authentication (it was broken in the clean up of WPA
553 state machine interface in v0.4.5)
554 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
555 sure the driver configures broadcast decryption correctly
556 * added ca_path (and ca_path2) configuration variables that can be used
557 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
558 system-wide trusted CA list
559 * added support for starting wpa_supplicant without a configuration
560 file (-C argument must be used to set ctrl_interface parameter for
561 this case; in addition, -p argument can be used to provide
562 driver_param; these new arguments can also be used with a
563 configuration to override the values from the configuration)
564 * added global control interface that can be optionally used for adding
565 and removing network interfaces dynamically (-g command line argument
566 for both wpa_supplicant and wpa_cli) without having to restart
567 wpa_supplicant process
569 - try to save configuration whenever something is modified
570 - added WEP key configuration
571 - added possibility to edit the current network configuration
572 * driver_ndis: fixed driver polling not to increase frequency on each
573 received EAPOL frame due to incorrectly cancelled timeout
574 * added simple configuration file examples (in examples subdirectory)
575 * fixed driver_wext.c to filter wireless events based on ifindex to
576 avoid interfaces receiving events from other interfaces
577 * delay sending initial EAPOL-Start couple of seconds to speed up
578 authentication for the most common case of Authenticator starting
579 EAP authentication immediately after association
582 * added a workaround for clearing keys with ndiswrapper to allow
583 roaming from WPA enabled AP to plaintext one
584 * added docbook documentation (doc/docbook) that can be used to
585 generate, e.g., man pages
586 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
587 PF_PACKET in order to prepare for network devices that do not use
588 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
589 * use receipt of EAPOL-Key frame as a lower layer success indication
590 for EAP state machine to allow recovery from dropped EAP-Success
592 * cleaned up internal EAPOL frame processing by not including link
593 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
594 header is added only when transmitted the frame; this makes it easier
595 to use wpa_supplicant on link layers that use different header than
597 * updated EAP-PSK to use draft 9 by default since this can now be
598 tested with hostapd; removed support for draft 3, including
599 server_nai configuration option from network blocks
600 * driver_wired: add PAE address to the multicast address list in order
601 to be able to receive EAPOL frames with drivers that do not include
602 these multicast addresses by default
603 * driver_wext: add support for WE-19
604 * added support for multiple configuration backends (CONFIG_BACKEND
605 option); currently, only 'file' is supported (i.e., the format used
606 in wpa_supplicant.conf)
607 * added support for updating configuration ('wpa_cli save_config');
608 this is disabled by default and can be enabled with global
609 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
610 and wpa_gui to store the configuration changes in a permanent store
611 * added GET_NETWORK ctrl_iface command
612 (e.g., 'wpa_cli get_network 0 ssid')
615 * replaced OpenSSL patch for EAP-FAST support
616 (openssl-tls-extensions.patch) with a more generic and correct
617 patch (the new patch is not compatible with the previous one, so the
618 OpenSSL library will need to be patched with the new patch in order
619 to be able to build wpa_supplicant with EAP-FAST support)
620 * added support for using Windows certificate store (through CryptoAPI)
621 for client certificate and private key operations (EAP-TLS)
622 (see wpa_supplicant.conf for more information on how to configure
623 this with private_key)
624 * ported wpa_gui to Windows
625 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
626 built with the open source version of the Qt4 for Windows
627 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
628 with drivers that do not support WPA
629 * ndis_events: fixed Windows 2000 support
630 * added support for enabling/disabling networks from the list of all
631 configured networks ('wpa_cli enable_network <network id>' and
632 'wpa_cli disable_network <network id>')
633 * added support for adding and removing network from the current
634 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
635 <network id>'); added networks are disabled by default and they can
636 be enabled with enable_network command once the configuration is done
637 for the new network; note: configuration file is not yet updated, so
638 these new networks are lost when wpa_supplicant is restarted
639 * added support for setting network configuration parameters through
640 the control interface, for example:
641 wpa_cli set_network 0 ssid "\"my network\""
642 * fixed parsing of strings that include both " and # within double
643 quoted area (e.g., "start"#end")
644 * added EAP workaround for PEAP session resumption: allow outer,
645 i.e., not tunneled, EAP-Success to terminate session since; this can
646 be disabled with eap_workaround=0
647 (this was allowed for PEAPv1 before, but now it is also allowed for
648 PEAPv0 since at least one RADIUS authentication server seems to be
649 doing this for PEAPv0, too)
650 * wpa_gui: added preliminary support for adding new networks to the
651 wpa_supplicant configuration (double click on the scan results to
652 open network configuration)
655 * removed interface for external EAPOL/EAP supplicant (e.g.,
656 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
657 anymore and is unlikely to be used by anyone
658 * driver_ndis: fixed WinPcap 3.0 support
659 * fixed build with CONFIG_DNET_PCAP=y on Linux
660 * l2_packet: moved different implementations into separate files
664 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
665 (note: ipw2100-1.1.0 is likely to require an update to work with
667 * added support for using ap_scan=2 mode with multiple network blocks;
668 wpa_supplicant will go through the networks one by one until the
669 driver reports a successful association; this uses the same order for
670 networks as scan_ssid=1 scans, i.e., the priority field is ignored
671 and the network block order in the file is used instead
672 * fixed a potential issue in RSN pre-authentication ending up using
673 freed memory if pre-authentication times out
674 * added support for matching alternative subject name extensions of the
675 authentication server certificate; new configuration variables
676 altsubject_match and altsubject_match2
677 * driver_ndis: added support for IEEE 802.1X authentication with wired
679 * added support for querying private key password (EAP-TLS) through the
680 control interface (wpa_cli/wpa_gui) if one is not included in the
682 * driver_broadcom: fixed couple of memory leaks in scan result
684 * EAP-PAX is now registered as EAP type 46
685 * fixed EAP-PAX MAC calculation
686 * fixed EAP-PAX CK and ICK key derivation
687 * added support for using password with EAP-PAX (as an alternative to
688 entering key with eappsk); SHA-1 hash of the password will be used as
690 * added support for arbitrary driver interface parameters through the
691 configuration file with a new driver_param field; this adds a new
692 driver_ops function set_param()
693 * added possibility to override l2_packet module with driver interface
694 API (new send_eapol handler); this can be used to implement driver
695 specific TX/RX functions for EAPOL frames
696 * fixed ctrl_interface_group processing for the case where gid is
697 entered as a number, not group name
698 * driver_test: added support for testing hostapd with wpa_supplicant
699 by using test driver interface without any kernel drivers or network
703 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
704 packets to be encrypted; this was apparently broken by the changed
705 ioctl order in v0.4.0
706 * driver_madwifi: added preliminary support for compiling against 'BSD'
707 branch of madwifi CVS tree
708 * added support for EAP-MSCHAPv2 password retries within the same EAP
709 authentication session
710 * added support for password changes with EAP-MSCHAPv2 (used when the
711 password has expired)
712 * added support for reading additional certificates from PKCS#12 files
713 and adding them to the certificate chain
714 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
716 * fixed a possible double free in EAP-TTLS fast-reauthentication when
717 identity or password is entered through control interface
718 * display EAP Notification messages to user through control interface
719 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
720 * added GUI version of wpa_cli, wpa_gui; this is not build
721 automatically with 'make'; use 'make wpa_gui' to build (this requires
722 Qt development tools)
723 * added 'disconnect' command to control interface for setting
724 wpa_supplicant in state where it will not associate before
725 'reassociate' command has been used
726 * added support for selecting a network from the list of all configured
727 networks ('wpa_cli select_network <network id>'; this disabled all
728 other networks; to re-enable, 'wpa_cli select_network any')
729 * added support for getting scan results through control interface
730 * added EAP workaround for PEAPv1 session resumption: allow outer,
731 i.e., not tunneled, EAP-Success to terminate session since; this can
732 be disabled with eap_workaround=0
734 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
735 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
736 used to reduce the size of the wpa_supplicant considerably if
737 debugging code is not needed
738 * fixed EAPOL-Key validation to drop packets with invalid Key Data
739 Length; such frames could have crashed wpa_supplicant due to buffer
741 * added support for wired authentication (IEEE 802.1X on wired
742 Ethernet); driver interface 'wired'
743 * obsoleted set_wpa() handler in the driver interface API (it can be
744 replaced by moving enable/disable functionality into init()/deinit())
745 (calls to set_wpa() are still present for backwards compatibility,
746 but they may be removed in the future)
747 * driver_madwifi: fixed association in plaintext mode
748 * modified the EAP workaround that accepts EAP-Success with incorrect
749 Identifier to be even less strict about verification in order to
750 interoperate with some authentication servers
751 * added support for sending TLS alerts
752 * added support for 'any' SSID wildcard; if ssid is not configured or
753 is set to an empty string, any SSID will be accepted for non-WPA AP
754 * added support for asking PIN (for SIM) from frontends (e.g.,
755 wpa_cli); if a PIN is needed, but not included in the configuration
756 file, a control interface request is sent and EAP processing is
757 delayed until the PIN is available
758 * added support for using external devices (e.g., a smartcard) for
759 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
760 new wpa_supplicant.conf variables:
761 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
762 - network: engine, engine_id, key_id
763 * added experimental support for EAP-PAX
764 * added monitor mode for wpa_cli (-a<path to a program to run>) that
765 allows external commands (e.g., shell scripts) to be run based on
766 wpa_supplicant events, e.g., when authentication has been completed
767 and data connection is ready; other related wpa_cli arguments:
768 -B (run in background), -P (write PID file); wpa_supplicant has a new
769 command line argument (-W) that can be used to make it wait until a
770 control interface command is received in order to avoid missing
772 * added support for opportunistic WPA2 PMKSA key caching (disabled by
773 default, can be enabled with proactive_key_caching=1)
774 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
775 Authenticator rejects PMKSA caching attempt and the driver is not
776 using assoc_info events
777 * added -P<pid file> argument for wpa_supplicant to write the current
778 process id into a file
780 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
781 * added new phase1 option parameter, include_tls_length=1, to force
782 wpa_supplicant to add TLS Message Length field to all TLS messages
783 even if the packet is not fragmented; this may be needed with some
784 authentication servers
785 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
786 using drivers that take care of AP selection (e.g., when using
788 * fixed reprocessing of pending request after ctrl_iface requests for
789 identity/password/otp
790 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
791 EAP-PEAP and EAP-TTLS
792 * all drivers using driver_wext: set interface up and select Managed
793 mode when starting wpa_supplicant; set interface down when exiting
794 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
795 ipw2100 and ipw2200; please note that this also changed the
796 configuration variable in .config to CONFIG_DRIVER_IPW
799 * fixed a busy loop introduced in v0.3.5 for scan result processing
800 when no matching AP is found
803 * added a workaround for an interoperability issue with a Cisco AP
805 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
806 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
807 retransmission of dropped frames)
808 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
809 (e.g., segfault when processing EAPOL-Key frames)
810 * fixed EAP workaround and fast reauthentication configuration for
811 RSN pre-authentication; previously these were disabled and
812 pre-authentication would fail if the used authentication server
813 requires EAP workarounds
814 * added support for blacklisting APs that fail or timeout
815 authentication in ap_scan=1 mode so that all APs are tried in cases
816 where the ones with strongest signal level are failing authentication
817 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
818 authentication attempt
819 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
820 in the previous authentication (previously, only Phase 1 success was
824 * added preliminary support for IBSS (ad-hoc) mode configuration
825 (mode=1 in network block); this included a new key_mgmt mode
826 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
827 key management; see wpa_supplicant.conf for more details and an
828 example on how to configure this (note: this is currently implemented
829 only for driver_hostapd.c, but the changes should be trivial to add
830 in associate() handler for other drivers, too (assuming the driver
832 * added preliminary port for native Windows (i.e., no cygwin) using
836 * added optional support for GNU Readline and History Libraries for
837 wpa_cli (CONFIG_READLINE)
838 * cleaned up EAP state machine <-> method interface and number of
839 small problems with error case processing not terminating on
840 EAP-Failure but waiting for timeout
841 * added couple of workarounds for interoperability issues with a
842 Cisco AP when using WPA2
843 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
844 Note: This requires a patch for openssl to add support for TLS
845 extensions and number of workarounds for operations without
846 certificates. Proof of concept type of experimental patch is
847 included in openssl-tls-extensions.patch.
850 * fixed private key loading for cases where passphrase is not set
851 * fixed Windows/cygwin L2 packet handler freeing; previous version
852 could cause a segfault when RSN pre-authentication was completed
853 * added support for PMKSA caching with drivers that generate RSN IEs
854 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
855 but similar code can be easily added to driver_ndiswrapper.c once
856 ndiswrapper gets full support for RSN PMKSA caching
857 * improved recovery from PMKID mismatches by requesting full EAP
858 authentication in case of failed PMKSA caching attempt
859 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
860 (this requires that ndis_events is ran while wpa_supplicant is
862 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
863 * added support for driver interfaces to replace the interface name
864 based on driver/OS specific mapping, e.g., in case of driver_ndis,
865 this allows the beginning of the adapter description to be used as
867 * added support for CR+LF (Windows-style) line ends in configuration
869 * driver_ndis: enable radio before starting scanning, disable radio
871 * modified association event handler to set portEnabled = FALSE before
872 clearing port Valid in order to reset EAP state machine and avoid
873 problems with new authentication getting ignored because of state
874 machines ending up in AUTHENTICATED/SUCCESS state based on old
876 * added support for driver events to add PMKID candidates in order to
877 allow drivers to give priority to most likely roaming candidates
878 * driver_hostap: moved PrivacyInvoked configuration to associate()
879 function so that this will not be set for plaintext connections
880 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
881 interface can distinguish plaintext and IEEE 802.1X (no WPA)
883 * fixed static WEP key configuration to use broadcast/default type for
884 all keys (previously, the default TX key was configured as pairwise/
886 * driver_ndis: added legacy WPA capability detection for non-WPA2
888 * added support for setting static WEP keys for IEEE 802.1X without
889 dynamic WEP keying (eapol_flags=0)
892 * added support for reading PKCS#12 (PFX) files (as a replacement for
893 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
894 * fixed compilation with CONFIG_PCSC=y
895 * added new ap_scan mode, ap_scan=2, for drivers that take care of
896 association, but need to be configured with security policy and SSID,
897 e.g., ndiswrapper and NDIS driver; this mode should allow such
898 drivers to work with hidden SSIDs and optimized roaming; when
899 ap_scan=2 is used, only the first network block in the configuration
900 file is used and this configuration should have explicit security
901 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
902 group, proto variables
903 * added experimental port of wpa_supplicant for Windows
904 - driver_ndis.c driver interface (NDIS OIDs)
905 - currently, this requires cygwin and WinPcap
906 - small utility, win_if_list, can be used to get interface name
907 * control interface can now be removed at build time; add
908 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
909 * optional Xsupplicant interface can now be removed at build time;
910 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
911 * added auth_alg to driver interface associate() parameters to make it
912 easier for drivers to configure authentication algorithm as part of
915 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
916 * driver_broadcom: added new driver interface for Broadcom wl.o driver
917 (a generic driver for Broadcom IEEE 802.11a/g cards)
918 * wpa_cli: fixed parsing of -p <path> command line argument
919 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
920 ACK, not tunneled EAP-Success (of which only the first byte was
921 actually send due to a bug in previous code); this seems to
922 interoperate with most RADIUS servers that implements PEAPv1
923 * PEAPv1: added support for terminating PEAP authentication on tunneled
924 EAP-Success message; this can be configured by adding
925 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
926 (some RADIUS servers require this whereas others require a tunneled
928 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
929 the old label for key derivation; previously, the default was 1,
930 but it looks like most existing PEAPv1 implementations use the old
931 label which is thus more suitable default option
932 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
933 * fixed parsing of wep_tx_keyidx
934 * added support for configuring list of allowed Phase 2 EAP types
935 (for both EAP-PEAP and EAP-TTLS) instead of only one type
936 * added support for configuring IEEE 802.11 authentication algorithm
937 (auth_alg; mainly for using Shared Key authentication with static
939 * added support for EAP-AKA (with UMTS SIM)
940 * fixed couple of errors in PCSC handling that could have caused
941 random-looking errors for EAP-SIM
942 * added support for EAP-SIM pseudonyms and fast re-authentication
943 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
945 * added support for EAP-SIM with two challanges
946 (phase1="sim_min_num_chal=3" can be used to require three challenges)
947 * added support for configuring DH/DSA parameters for an ephemeral DH
948 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
949 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
950 and optional DH key exchange to achieve forward secracy with RSA keys
951 * added support for matching subject of the authentication server
952 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
953 configuration variables subject_match and subject_match2
954 * changed SSID configuration in driver_wext.c (used by many driver
955 interfaces) to use ssid_len+1 as the length for SSID since some Linux
957 * fixed couple of unaligned reads in scan result parsing to fix WPA
958 connection on some platforms (e.g., ARM)
959 * added driver interface for Intel ipw2100 driver
960 * added support for LEAP with WPA
961 * added support for larger scan results report (old limit was 4 kB of
962 data, i.e., about 35 or so APs) when using Linux wireless extensions
964 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
965 only if there is a PMKSA cache entry for the current AP
966 * fixed error handling for case where reading of scan results fails:
967 must schedule a new scan or wpa_supplicant will remain waiting
969 * changed debug output to remove shared password/key material by
970 default; all key information can be included with -K command line
971 argument to match the previous behavior
972 * added support for timestamping debug log messages (disabled by
973 default, can be enabled with -t command line argument)
974 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
975 if keys are not configured to be used; this fixes IEEE 802.1X mode
976 with drivers that use this information to configure whether Privacy
977 bit can be in Beacon frames (e.g., ndiswrapper)
978 * avoid clearing driver keys if no keys have been configured since last
979 key clear request; this seems to improve reliability of group key
980 handshake for ndiswrapper & NDIS driver which seems to be suffering
981 of some kind of timing issue when the keys are cleared again after
983 * changed driver interface API:
984 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
985 version is being used (now, this is set to 2; previously, it was
987 - pass pointer to private data structure to all calls
988 - the new API is not backwards compatible; all in-tree driver
989 interfaces has been converted to the new API
990 * added support for controlling multiple interfaces (radios) per
991 wpa_supplicant process; each interface needs to be listed on the
992 command line (-c, -i, -D arguments) with -N as a separator
993 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
994 * added a workaround for EAP servers that incorrectly use same Id for
995 sequential EAP packets
996 * changed libpcap/libdnet configuration to use .config variable,
997 CONFIG_DNET_PCAP, instead of requiring Makefile modification
998 * improved downgrade attack detection in IE verification of msg 3/4:
999 verify both WPA and RSN IEs, if present, not only the selected one;
1000 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
1001 Probe Response frame, and RSN is enabled in wpa_supplicant
1003 * fixed WPA msg 3/4 processing to allow Key Data field contain other
1004 IEs than just one WPA IE
1005 * added support for FreeBSD and driver interface for the BSD net80211
1006 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
1007 required kernel mods have not yet been committed
1008 * made EAP workarounds configurable; enabled by default, can be
1009 disabled with network block option eap_workaround=0
1011 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
1012 * resolved couple of interoperability issues with EAP-PEAPv1 and
1013 Phase 2 (inner EAP) fragment reassembly
1014 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
1015 AP is using non-zero key index for the unicast key and key index zero
1016 for the broadcast key
1017 * driver_hostap: fixed IEEE 802.1X WEP key updates and
1018 re-authentication by allowing unencrypted EAPOL frames when not using
1020 * added a new driver interface, 'wext', which uses only standard,
1021 driver independent functionality in Linux wireless extensions;
1022 currently, this can be used only for non-WPA IEEE 802.1X mode, but
1023 eventually, this is to be extended to support full WPA/WPA2 once
1024 Linux wireless extensions get support for this
1025 * added support for mode in which the driver is responsible for AP
1026 scanning and selection; this is disabled by default and can be
1027 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
1028 this mode can be used, e.g., with generic 'wext' driver interface to
1029 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
1030 supporting wireless extensions.
1031 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
1032 operation with an AP that does not include SSID in the Beacon frames)
1033 * added support for new EAP authentication methods:
1034 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
1035 * added support for asking one-time-passwords from frontends (e.g.,
1036 wpa_cli); this 'otp' command works otherwise like 'password' command,
1037 but the password is used only once and the frontend will be asked for
1038 a new password whenever a request from authenticator requires a
1039 password; this can be used with both EAP-OTP and EAP-GTC
1040 * changed wpa_cli to automatically re-establish connection so that it
1041 does not need to be re-started when wpa_supplicant is terminated and
1043 * improved user data (identity/password/otp) requests through
1044 frontends: process pending EAPOL packets after getting new
1045 information so that full authentication does not need to be
1046 restarted; in addition, send pending requests again whenever a new
1047 frontend is attached
1048 * changed control frontends to use a new directory for socket files to
1049 make it easier for wpa_cli to automatically select between interfaces
1050 and to provide access control for the control interface;
1051 wpa_supplicant.conf: ctrl_interface is now a path
1052 (/var/run/wpa_supplicant is the recommended path) and
1053 ctrl_interface_group can be used to select which group gets access to
1054 the control interface;
1055 wpa_cli: by default, try to connect to the first interface available
1056 in /var/run/wpa_supplicant; this path can be overriden with -p option
1057 and an interface can be selected with -i option (i.e., in most common
1058 cases, wpa_cli does not need to get any arguments)
1059 * added support for LEAP
1060 * added driver interface for Linux ndiswrapper
1061 * added priority option for network blocks in the configuration file;
1062 this allows networks to be grouped based on priority (the scan
1063 results are searched for matches with network blocks in this order)
1066 * sort scan results to improve AP selection
1067 * fixed control interface socket removal for some error cases
1068 * improved scan requesting and authentication timeout
1069 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1071 * PEAP version can now be forced with phase1="peapver=<ver>"
1072 (mostly for testing; by default, the highest version supported by
1073 both the Supplicant and Authentication Server is selected
1075 * added support for madwifi driver (Atheros ar521x)
1076 * added a workaround for cases where AP sets Install Tx/Rx bit for
1077 WPA Group Key messages when pairwise keys are used (without this,
1078 the Group Key would be used for Tx and the AP would drop frames
1080 * added GSM SIM/USIM interface for GSM authentication algorithm for
1081 EAP-SIM; this requires pcsc-lite
1082 * added support for ATMEL AT76C5XXx driver
1083 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1084 does not include key data in the EAPOL-Key frame (i.e., part of
1085 EAP keying material is used as data encryption key)
1086 * added support for using plaintext and static WEP networks
1090 * added support for new EAP authentication methods:
1091 EAP-TTLS/EAP-MD5-Challenge
1093 EAP-TTLS/EAP-MSCHAPv2
1101 EAP-PEAP/MD5-Challenge
1103 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1104 * added support for anonymous identity (to be used when identity is
1105 sent in plaintext; real identity will be used within TLS protected
1106 tunnel (e.g., with EAP-TTLS)
1107 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1108 * added support for requesting identity and password information using
1109 control interface; in other words, the password for EAP-PEAP or
1110 EAP-TTLS does not need to be included in the configuration file since
1111 a frontand (e.g., wpa_cli) can ask it from the user
1112 * improved RSN pre-authentication to use a candidate list and process
1113 all candidates from each scan; not only one per scan
1114 * fixed RSN IE and WPA IE capabilities field parsing
1115 * ignore Tx bit in GTK IE when Pairwise keys are used
1116 * avoid making new scan requests during IEEE 802.1X negotiation
1117 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1118 with TLS support (this replaces the included implementation with
1119 library code to save about 8 kB since the library code is needed
1121 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1122 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1125 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1127 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1128 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1129 - EAP-MD5 (cannot be used with WPA-RADIUS)
1130 [draft-ietf-eap-rfc2284bis-09.txt]
1131 - EAP-TLS [RFC 2716]
1132 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1133 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1134 [draft-kamath-pppext-eap-mschapv2-00.txt]
1135 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1136 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1137 - new configuration file options: eap, identity, password, ca_cert,
1138 client_cert, privatekey, private_key_passwd
1139 - Xsupplicant is not required anymore, but it can be used by
1140 disabling the internal IEEE 802.1X Supplicant with -e command line
1142 - this code is not included in the default build; Makefile need to
1143 be edited for this (uncomment lines for selected functionality)
1144 - EAP-TLS and EAP-PEAP require openssl libraries
1145 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1146 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1147 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1148 EAPOL-Key frames instead of WPA key handshakes)
1149 * added support for IEEE 802.11i/RSN (WPA2)
1150 - improved PTK Key Handshake
1151 - PMKSA caching, pre-authentication
1152 * fixed wpa_supplicant to ignore possible extra data after WPA
1153 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1154 TPTK' error from message 3 of 4-Way Handshake in case the AP
1155 includes extra data after the EAPOL-Key)
1156 * added interface for external programs (frontends) to control
1158 - CLI example (wpa_cli) with interactive mode and command line
1160 - replaced SIGUSR1 status/statistics with the new control interface
1161 * made some feature compile time configurable
1162 - .config file for make
1163 - driver interfaces (hostap, hermes, ..)
1164 - EAPOL/EAP functions
1167 * Initial version of wpa_supplicant
