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
15 * added support for WPS USBA out-of-band mechanism with USB Flash
16 Drives (UFD) (CONFIG_WPS_UFD=y)
17 * driver_ndis: add PAE group address to the multicast address list to
18 fix wired IEEE 802.1X authentication
19 * fixed IEEE 802.11r key derivation function to match with the standard
20 (note: this breaks interoperability with previous version) [Bug 303]
23 * added support for Wi-Fi Protected Setup (WPS)
24 (wpa_supplicant can now be configured to act as a WPS Enrollee to
25 enroll credentials for a network using PIN and PBC methods; in
26 addition, wpa_supplicant can act as a wireless WPS Registrar to
27 configure an AP); WPS support can be enabled by adding CONFIG_WPS=y
28 into .config and setting the runtime configuration variables in
29 wpa_supplicant.conf (see WPS section in the example configuration
30 file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to
31 manage WPS negotiation; see README-WPS for more details
32 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
33 * added support for using driver_test over UDP socket
34 * fixed PEAPv0 Cryptobinding interoperability issue with Windows Server
35 2008 NPS; optional cryptobinding is now enabled (again) by default
36 * fixed PSK editing in wpa_gui
37 * changed EAP-GPSK to use the IANA assigned EAP method type 51
38 * added a Windows installer that includes WinPcap and all the needed
39 DLLs; in addition, it set up the registry automatically so that user
40 will only need start wpa_gui to get prompted to start the wpasvc
41 servide and add a new interface if needed through wpa_gui dialog
42 * updated management frame protection to use IEEE 802.11w/D7.0
45 * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
46 (can be used to simulate test SIM/USIM card with a known private key;
47 enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
48 and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
49 * added a new network configuration option, wpa_ptk_rekey, that can be
50 used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
51 against TKIP deficiencies
52 * added an optional mitigation mechanism for certain attacks against
53 TKIP by delaying Michael MIC error reports by a random amount of time
54 between 0 and 60 seconds; this can be enabled with a build option
55 CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
56 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
58 * updated OpenSSL code for EAP-FAST to use an updated version of the
59 session ticket overriding API that was included into the upstream
60 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
61 needed with that version anymore)
62 * updated userspace MLME instructions to match with the current Linux
63 mac80211 implementation; please also note that this can only be used
64 with driver_nl80211.c (the old code from driver_wext.c was removed)
65 * added support (Linux only) for RoboSwitch chipsets (often found in
66 consumer grade routers); driver interface 'roboswitch'
67 * fixed canceling of PMKSA caching when using drivers that generate
68 RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
72 * added support for SHA-256 as X.509 certificate digest when using the
73 internal X.509/TLSv1 implementation
74 * updated management frame protection to use IEEE 802.11w/D6.0
75 * added support for using SHA256-based stronger key derivation for WPA2
77 * fixed FT (IEEE 802.11r) authentication after a failed association to
79 * added support for configuring Phase 2 (inner/tunneled) authentication
80 method with wpa_gui-qt4
83 * added support for EAP Sequences in EAP-FAST Phase 2
84 * added support for using TNC with EAP-FAST
85 * added driver_ps3 for the PS3 Linux wireless driver
86 * added support for optional cryptobinding with PEAPv0
87 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
88 allow fallback to full handshake if server rejects PAC-Opaque
89 * added fragmentation support for EAP-TNC
90 * added support for parsing PKCS #8 formatted private keys into the
91 internal TLS implementation (both PKCS #1 RSA key and PKCS #8
92 encapsulated RSA key can now be used)
93 * added option of using faster, but larger, routines in the internal
94 LibTomMath (for internal TLS implementation) to speed up DH and RSA
95 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
96 * fixed race condition between disassociation event and group key
97 handshake to avoid getting stuck in incorrect state [Bug 261]
98 * fixed opportunistic key caching (proactive_key_caching)
101 * removed 'nai' and 'eappsk' network configuration variables that were
102 previously used for configuring user identity and key for EAP-PSK,
103 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
104 replacement for 'nai' (if old configuration used a separate
105 'identity' value, that would now be configured as
106 'anonymous_identity'). 'password' field is now used as the
107 replacement for 'eappsk' (it can also be set using hexstring to
108 present random binary data)
109 * removed '-w' command line parameter (wait for interface to be added,
110 if needed); cleaner way of handling this functionality is to use an
111 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
112 when an interface is added
113 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
114 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
115 indicating when new scan results become available
116 * added new ctrl_iface command, BSS, to allow scan results to be
117 fetched without hitting the message size limits (this command
118 can be used to iterate through the scan results one BSS at the time)
119 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
120 attributes in EAP-SIM Start/Response when using fast reauthentication
121 * fixed EAPOL not to end up in infinite loop when processing dynamic
122 WEP keys with IEEE 802.1X
123 * fixed problems in getting NDIS events from WMI on Windows 2000
126 * added support for Makefile builds to include debug-log-to-a-file
127 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
128 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
129 lengths properly to avoid potential crash caused by invalid messages
130 * added data structure for storing allocated buffers (struct wpabuf);
131 this does not affect wpa_supplicant usage, but many of the APIs
132 changed and various interfaces (e.g., EAP) is not compatible with old
134 * added support for protecting EAP-AKA/Identity messages with
135 AT_CHECKCODE (optional feature in RFC 4187)
136 * added support for protected result indication with AT_RESULT_IND for
137 EAP-SIM and EAP-AKA (phase1="result_ind=1")
138 * added driver_wext workaround for race condition between scanning and
139 association with drivers that take very long time to scan all
140 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
141 using a longer hardcoded timeout for the scan if the driver supports
142 notifications for scan completion (SIOCGIWSCAN event); this helps,
143 e.g., in cases where wpa_supplicant and madwifi driver ended up in
144 loop where the driver did not even try to associate
145 * stop EAPOL timer tick when no timers are in use in order to reduce
146 power consumption (no need to wake up the process once per second)
148 * added support for privilege separation (run only minimal part of
149 wpa_supplicant functionality as root and rest as unprivileged,
150 non-root process); see 'Privilege separation' in README for details;
151 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
153 * changed scan results data structure to include all information
154 elements to make it easier to support new IEs; old get_scan_result()
155 driver_ops is still supported for backwards compatibility (results
156 are converted internally to the new format), but all drivers should
157 start using the new get_scan_results2() to make them more likely to
158 work with new features
159 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
160 application, i.e., it does not require Qt3Support anymore; Windows
161 binary of wpa_gui.exe is now from this directory and only requires
162 QtCore4.dll and QtGui4.dll libraries
163 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
164 available as a separate package to make wpa_gui installation easier:
165 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
166 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
167 only shared key/password authentication is supported in this version
170 * added support for configuring password as NtPasswordHash
171 (16-byte MD4 hash of password) in hash:<32 hex digits> format
172 * added support for fallback from abbreviated TLS handshake to
173 full handshake when using EAP-FAST (e.g., due to an expired
175 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
176 draft (draft-ietf-emu-eap-gpsk-07.txt)
177 * added support for drivers that take care of RSN 4-way handshake
178 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
179 WPA_ALG_PMK in set_key)
180 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
181 .config); this version supports only ap_scan=2 mode and allow the
182 driver to take care of the 4-way handshake
183 * fixed a buffer overflow in parsing TSF from scan results when using
184 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
186 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
187 * fixed an integer overflow issue in the ASN.1 parser used by the
188 (experimental) internal TLS implementation to avoid a potential
190 * fixed a race condition with -W option (wait for a control interface
191 monitor before starting) that could have caused the first messages to
193 * added support for processing TNCC-TNCS-Messages to report
194 recommendation (allow/none/isolate) when using TNC [Bug 243]
197 * added network configuration parameter 'frequency' for setting
198 initial channel for IBSS (adhoc) networks
199 * added experimental IEEE 802.11r/D6.0 support
200 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
201 * updated EAP-PSK to use the IANA-allocated EAP type 47
202 * fixed EAP-PAX key derivation
203 * fixed EAP-PSK bit ordering of the Flags field
204 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
205 tunnelled identity request (previously, the identifier from the outer
206 method was used, not the tunnelled identifier which could be
208 * added support for fragmentation of outer TLS packets during Phase 2
209 of EAP-PEAP/TTLS/FAST
210 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
211 * added support for EAP-FAST authentication with inner methods that
212 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
213 for PAC provisioning)
214 * added support for authenticated EAP-FAST provisioning
215 * added support for configuring maximum number of EAP-FAST PACs to
216 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
217 * added support for storing EAP-FAST PACs in binary format
218 (fast_pac_format=binary in phase1 string)
219 * fixed dbus ctrl_iface to validate message interface before
220 dispatching to avoid a possible segfault [Bug 190]
221 * fixed PeerKey key derivation to use the correct PRF label
222 * updated Windows binary build to link against OpenSSL 0.9.8d and
223 added support for EAP-FAST
224 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
225 draft (draft-ietf-emu-eap-gpsk-04.txt)
226 * fixed EAP-AKA Notification processing to allow Notification to be
227 processed after AKA Challenge response has been sent
228 * updated to use IEEE 802.11w/D2.0 for management frame protection
230 * fixed EAP-TTLS implementation not to crash on use of freed memory
231 if TLS library initialization fails
232 * added support for EAP-TNC (Trusted Network Connect)
233 (this version implements the EAP-TNC method and EAP-TTLS changes
234 needed to run two methods in sequence (IF-T) and the IF-IMC and
235 IF-TNCCS interfaces from TNCC)
238 * added experimental, integrated TLSv1 client implementation with the
239 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
240 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
241 .config); this can be useful, e.g., if the target system does not
242 have a suitable TLS library and a minimal code size is required
243 (total size of this internal TLS/crypto code is bit under 50 kB on
244 x86 and the crypto code is shared by rest of the supplicant so some
245 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
246 * removed STAKey handshake since PeerKey handshake has replaced it in
247 IEEE 802.11ma and there are no known deployments of STAKey
248 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
249 draft (draft-ietf-emu-eap-gpsk-01.txt)
250 * added preliminary implementation of IEEE 802.11w/D1.0 (management
252 (Note: this requires driver support to work properly.)
253 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
254 * fixed Windows named pipes ctrl_iface to not stop listening for
255 commands if client program opens a named pipe and closes it
256 immediately without sending a command
257 * fixed USIM PIN status determination for the case that PIN is not
258 needed (this allows EAP-AKA to be used with USIM cards that do not
260 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
261 be used with cards that do not support file selection based on
263 * added support for matching the subjectAltName of the authentication
264 server certificate against multiple name components (e.g.,
265 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
266 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
267 affects IEEE 802.1X with dynamic WEP keys)
268 * changed ctrl_iface network configuration 'get' operations to not
269 return password/key material; if these fields are requested, "*"
270 will be returned if the password/key is set, but the value of the
271 parameter is not exposed
274 * added support for building Windows version with UNICODE defined
275 (wide-char functions)
276 * driver_ndis: fixed static WEP configuration to avoid race condition
277 issues with some NDIS drivers between association and setting WEP
279 * driver_ndis: added validation for IELength value in scan results to
280 avoid crashes when using buggy NDIS drivers [Bug 165]
281 * fixed Release|Win32 target in the Visual Studio project files
282 (previously, only Debug|Win32 target was set properly)
283 * changed control interface API call wpa_ctrl_pending() to allow it to
284 return -1 on error (e.g., connection lost); control interface clients
285 will need to make sure that they verify that the value is indeed >0
286 when determining whether there are pending messages
287 * added an alternative control interface backend for Windows targets:
288 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
289 control interface mechanism for Windows builds (previously, UDP to
291 * changed ctrl_interface configuration for UNIX domain sockets:
292 - deprecated ctrl_interface_group variable (it may be removed in
294 - allow both directory and group be configured with ctrl_interface
295 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
296 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
297 case when group is not changed
298 * added support for controlling more than one interface per process in
300 * added a workaround for a case where the AP is using unknown address
301 (e.g., MAC address of the wired interface) as the source address for
302 EAPOL-Key frames; previously, that source address was used as the
303 destination for EAPOL-Key frames and in key derivation; now, BSSID is
304 used even if the source address does not match with it
305 (this resolves an interoperability issue with Thomson SpeedTouch 580)
306 * added a workaround for UDP-based control interface (which was used in
307 Windows builds before this release) to prevent packets with forged
308 addresses from being accepted as local control requests
309 * removed ndis_events.cpp and possibility of using external
310 ndis_events.exe; C version (ndis_events.c) is fully functional and
311 there is no desire to maintain two separate versions of this
313 * ndis_events: Changed NDIS event notification design to use WMI to
314 learn the adapter description through Win32_PnPEntity class; this
315 should fix some cases where the adapter name was not recognized
316 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
318 * fixed selection of the first network in ap_scan=2 mode; previously,
319 wpa_supplicant could get stuck in SCANNING state when only the first
320 network for enabled (e.g., after 'wpa_cli select_network 0')
321 * winsvc: added support for configuring ctrl_interface parameters in
322 registry (ctrl_interface string value in
323 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
324 required to enable control interface (previously, this was hardcoded
326 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
327 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
330 * fixed build with CONFIG_STAKEY=y [Bug 143]
331 * added support for doing MLME (IEEE 802.11 management frame
332 processing) in wpa_supplicant when using Devicescape IEEE 802.11
333 stack (wireless-dev.git tree)
334 * added a new network block configuration option, fragment_size, to
335 configure the maximum EAP fragment size
336 * driver_ndis: Disable WZC automatically for the selected interface to
337 avoid conflicts with two programs trying to control the radio; WZC
338 will be re-enabled (if it was enabled originally) when wpa_supplicant
340 * added an experimental TLSv1 client implementation
341 (CONFIG_TLS=internal) that can be used instead of an external TLS
342 library, e.g., to reduce total size requirement on systems that do
343 not include any TLS library by default (this is not yet complete;
344 basic functionality is there, but certificate validation is not yet
346 * added PeerKey handshake implementation for IEEE 802.11e
347 direct link setup (DLS) to replace STAKey handshake
348 * fixed WPA PSK update through ctrl_iface for the case where the old
349 PSK was derived from an ASCII passphrase and the new PSK is set as
350 a raw PSK (hex string)
351 * added new configuration option for identifying which network block
352 was used (id_str in wpa_supplicant.conf; included on
353 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
354 variable in wpa_cli action scripts; in addition WPA_ID variable is
355 set to the current unique identifier that wpa_supplicant assigned
356 automatically for the network and that can be used with
357 GET_NETWORK/SET_NETWORK ctrl_iface commands)
358 * wpa_cli action script is now called only when the connect/disconnect
359 status changes or when associating with a different network
360 * fixed configuration parser not to remove CCMP from group cipher list
361 if WPA-None (adhoc) is used (pairwise=NONE in that case)
362 * fixed integrated NDIS events processing not to hang the process due
363 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
364 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
365 draft-clancy-emu-eap-shared-secret-00.txt)
366 * added Microsoft Visual Studio 2005 solution and project files for
367 build wpa_supplicant for Windows (see vs2005 subdirectory)
368 * eloop_win: fixed unregistration of Windows events
369 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
370 at the end of RSN pre-authentication and added unregistration of
371 a Windows event to avoid getting eloop_win stuck with an invalid
373 * driver_ndis: added support for selecting AP based on BSSID
374 * added new environmental variable for wpa_cli action scripts:
375 WPA_CTRL_DIR is the current control interface directory
376 * driver_ndis: added support for using NDISUIO instead of WinPcap for
377 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
378 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
379 wpa_supplicant without requiring WinPcap; note that using NDISUIO
380 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
381 only one application to open the device
382 * changed NDIS driver naming to only include device GUID, e.g.,
383 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
384 specific \Device\NPF_ prefix before the GUID; the prefix is still
385 allowed for backwards compatibility, but it is not required anymore
386 when specifying the interface
387 * driver_ndis: re-initialize driver interface is the adapter is removed
388 and re-inserted [Bug 159]
389 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
390 big endian hosts [Bug 146]
393 * fixed EAP-GTC response to include correct user identity when run as
394 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
395 * driver_ndis: Fixed encryption mode configuration for unencrypted
396 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
397 refused to associate with open networks) [Bug 106]
398 * driver_ndis: use BSSID OID polling to detect when IBSS network is
399 formed even when ndis_events code is included since some NDIS drivers
400 do not generate media connect events in IBSS mode
401 * config_winreg: allow global ctrl_interface parameter to be configured
403 * config_winreg: added support for saving configuration data into
405 * added support for controlling network device operational state
406 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
407 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
408 that can use this information)
409 * driver_wext: added support for WE-21 change to SSID configuration
410 * driver_wext: fixed privacy configuration for static WEP keys mode
412 * added an optional driver_ops callback for MLME-SETPROTECTION.request
414 * added support for EAP-SAKE (no EAP method number allocated yet, so
415 this is using the same experimental type 255 as EAP-PSK)
416 * added support for dynamically loading EAP methods (.so files) instead
417 of requiring them to be statically linked in; this is disabled by
418 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
422 * do not try to use USIM APDUs when initializing PC/SC for SIM card
423 access for a network that has not enabled EAP-AKA
424 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
425 v0.5.1 due to the new support for expanded EAP types)
426 * added support for generating EAP Expanded Nak
427 * try to fetch scan results once before requesting new scan when
428 starting up in ap_scan=1 mode (this can speed up initial association
429 a lot with, e.g., madwifi-ng driver)
430 * added support for receiving EAPOL frames from a Linux bridge
431 interface (-bbr0 on command line)
432 * fixed EAPOL re-authentication for sessions that used PMKSA caching
433 * changed EAP method registration to use a dynamic list of methods
434 instead of a static list generated at build time
435 * fixed PMKSA cache deinitialization not to use freed memory when
436 removing PMKSA entries
437 * fixed a memory leak in EAP-TTLS re-authentication
438 * reject WPA/WPA2 message 3/4 if it does not include any valid
440 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
441 if the driver does not support SIOCSIWAUTH
444 * driver_test: added better support for multiple APs and STAs by using
445 a directory with sockets that include MAC address for each device in
446 the name (driver_param=test_dir=/tmp/test)
447 * added support for EAP expanded type (vendor specific EAP methods)
448 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
449 option can be changed if needed
450 * wpa_cli/wpa_gui: skip non-socket files in control directory when
451 using UNIX domain sockets; this avoids selecting an incorrect
452 interface (e.g., a PID file could be in this directory, even though
453 use of this directory for something else than socket files is not
455 * fixed TLS library deinitialization after RSN pre-authentication not
456 to disable TLS library for normal authentication
457 * driver_wext: Remove null-termination from SSID length if the driver
458 used it; some Linux drivers do this and they were causing problems in
459 wpa_supplicant not finding matching configuration block. This change
460 would break a case where the SSID actually ends in '\0', but that is
461 not likely to happen in real use.
462 * fixed PMKSA cache processing not to trigger deauthentication if the
463 current PMKSA cache entry is replaced with a valid new entry
464 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
465 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
468 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
469 * added experimental STAKey handshake implementation for IEEE 802.11e
470 direct link setup (DLS); note: this is disabled by default in both
471 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
473 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
474 decrypt AT_ENCR_DATA attributes correctly
475 * fixed EAP-AKA to allow resynchronization within the same session
476 * made code closer to ANSI C89 standard to make it easier to port to
477 other C libraries and compilers
478 * started moving operating system or C library specific functions into
479 wrapper functions defined in os.h and implemented in os_*.c to make
481 * wpa_supplicant can now be built with Microsoft Visual C++
482 (e.g., with the freely available Toolkit 2003 version or Visual
483 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
484 example makefile for nmake
485 * added support for using Windows registry for command line parameters
486 (CONFIG_MAIN=main_winsvc) and configuration data
487 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
488 contents; this version can be run both as a Windows service and as a
489 normal application; 'wpasvc.exe app' to start as applicant,
490 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
491 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
493 * made it possible to link ndis_events.exe functionality into
494 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
495 * added better support for multiple control interface backends
496 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
497 * fixed PC/SC code to use correct length for GSM AUTH command buffer
498 and to not use pioRecvPci with SCardTransmit() calls; these were not
499 causing visible problems with pcsc-lite, but Windows Winscard.dll
500 refused the previously used parameters; this fixes EAP-SIM and
501 EAP-AKA authentication using SIM/USIM card under Windows
502 * added new event loop implementation for Windows using
503 WaitForMultipleObject() instead of select() in order to allow waiting
504 for non-socket objects; this can be selected with
505 CONFIG_ELOOP=eloop_win in .config
506 * added support for selecting l2_packet implementation in .config
507 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
508 winpcap, freebsd, none)
509 * added new l2_packet implementation for WinPcap
510 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
511 reduce latency in EAPOL receive processing from about 100 ms to about
513 * added support for EAP-FAST key derivation using other ciphers than
514 RC4-128-SHA for authentication and AES128-SHA for provisioning
515 * added support for configuring CA certificate as DER file and as a
517 * fixed private key configuration as configuration blob and added
518 support for using PKCS#12 as a blob
519 * tls_gnutls: added support for using PKCS#12 files; added support for
521 * added support for loading trusted CA certificates from Windows
522 certificate store: ca_cert="cert_store://<name>", where <name> is
523 likely CA (Intermediate CA certificates) or ROOT (root certificates)
524 * added C version of ndis_events.cpp and made it possible to build this
525 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
526 easily on cross-compilation builds
527 * added wpasvc.exe into Windows binary release; this is an alternative
528 version of wpa_supplicant.exe with configuration backend using
529 Windows registry and with the entry point designed to run as a
531 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
532 wpasvc.exe and removed this additional tool from the Windows binary
533 release since it is not needed anymore
534 * load winscard.dll functions dynamically when building with MinGW
535 since MinGW does not yet include winscard library
537 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
538 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
539 and WinPcap to receive frames sent to PAE group address
540 * disable EAP state machine when IEEE 802.1X authentication is not used
541 in order to get rid of bogus "EAP failed" messages
542 * fixed OpenSSL error reporting to go through all pending errors to
543 avoid confusing reports of old errors being reported at later point
545 * fixed configuration file updating to not write empty variables
546 (e.g., proto or key_mgmt) that the file parser would not accept
547 * fixed ADD_NETWORK ctrl_iface command to use the same default values
548 for variables as empty network definitions read from config file
550 * fixed EAP state machine to not discard EAP-Failure messages in many
551 cases (e.g., during TLS handshake)
552 * fixed a infinite loop in private key reading if the configured file
553 cannot be parsed successfully
554 * driver_madwifi: added support for madwifi-ng
555 * wpa_gui: do not display password/PSK field contents
556 * wpa_gui: added CA certificate configuration
557 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
558 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
559 the new AP is using different WPA/RSN IE
560 * use longer timeout for IEEE 802.11 association to avoid problems with
561 drivers that may take more than five second to associate
564 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
565 RSN IE, but WPA IE would match with wpa_supplicant configuration
566 * added support for named configuration blobs in order to avoid having
567 to use file system for external files (e.g., certificates);
568 variables can be set to "blob://<blob name>" instead of file path to
569 use a named blob; supported fields: pac_file, client_cert,
571 * fixed RSN pre-authentication (it was broken in the clean up of WPA
572 state machine interface in v0.4.5)
573 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
574 sure the driver configures broadcast decryption correctly
575 * added ca_path (and ca_path2) configuration variables that can be used
576 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
577 system-wide trusted CA list
578 * added support for starting wpa_supplicant without a configuration
579 file (-C argument must be used to set ctrl_interface parameter for
580 this case; in addition, -p argument can be used to provide
581 driver_param; these new arguments can also be used with a
582 configuration to override the values from the configuration)
583 * added global control interface that can be optionally used for adding
584 and removing network interfaces dynamically (-g command line argument
585 for both wpa_supplicant and wpa_cli) without having to restart
586 wpa_supplicant process
588 - try to save configuration whenever something is modified
589 - added WEP key configuration
590 - added possibility to edit the current network configuration
591 * driver_ndis: fixed driver polling not to increase frequency on each
592 received EAPOL frame due to incorrectly cancelled timeout
593 * added simple configuration file examples (in examples subdirectory)
594 * fixed driver_wext.c to filter wireless events based on ifindex to
595 avoid interfaces receiving events from other interfaces
596 * delay sending initial EAPOL-Start couple of seconds to speed up
597 authentication for the most common case of Authenticator starting
598 EAP authentication immediately after association
601 * added a workaround for clearing keys with ndiswrapper to allow
602 roaming from WPA enabled AP to plaintext one
603 * added docbook documentation (doc/docbook) that can be used to
604 generate, e.g., man pages
605 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
606 PF_PACKET in order to prepare for network devices that do not use
607 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
608 * use receipt of EAPOL-Key frame as a lower layer success indication
609 for EAP state machine to allow recovery from dropped EAP-Success
611 * cleaned up internal EAPOL frame processing by not including link
612 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
613 header is added only when transmitted the frame; this makes it easier
614 to use wpa_supplicant on link layers that use different header than
616 * updated EAP-PSK to use draft 9 by default since this can now be
617 tested with hostapd; removed support for draft 3, including
618 server_nai configuration option from network blocks
619 * driver_wired: add PAE address to the multicast address list in order
620 to be able to receive EAPOL frames with drivers that do not include
621 these multicast addresses by default
622 * driver_wext: add support for WE-19
623 * added support for multiple configuration backends (CONFIG_BACKEND
624 option); currently, only 'file' is supported (i.e., the format used
625 in wpa_supplicant.conf)
626 * added support for updating configuration ('wpa_cli save_config');
627 this is disabled by default and can be enabled with global
628 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
629 and wpa_gui to store the configuration changes in a permanent store
630 * added GET_NETWORK ctrl_iface command
631 (e.g., 'wpa_cli get_network 0 ssid')
634 * replaced OpenSSL patch for EAP-FAST support
635 (openssl-tls-extensions.patch) with a more generic and correct
636 patch (the new patch is not compatible with the previous one, so the
637 OpenSSL library will need to be patched with the new patch in order
638 to be able to build wpa_supplicant with EAP-FAST support)
639 * added support for using Windows certificate store (through CryptoAPI)
640 for client certificate and private key operations (EAP-TLS)
641 (see wpa_supplicant.conf for more information on how to configure
642 this with private_key)
643 * ported wpa_gui to Windows
644 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
645 built with the open source version of the Qt4 for Windows
646 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
647 with drivers that do not support WPA
648 * ndis_events: fixed Windows 2000 support
649 * added support for enabling/disabling networks from the list of all
650 configured networks ('wpa_cli enable_network <network id>' and
651 'wpa_cli disable_network <network id>')
652 * added support for adding and removing network from the current
653 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
654 <network id>'); added networks are disabled by default and they can
655 be enabled with enable_network command once the configuration is done
656 for the new network; note: configuration file is not yet updated, so
657 these new networks are lost when wpa_supplicant is restarted
658 * added support for setting network configuration parameters through
659 the control interface, for example:
660 wpa_cli set_network 0 ssid "\"my network\""
661 * fixed parsing of strings that include both " and # within double
662 quoted area (e.g., "start"#end")
663 * added EAP workaround for PEAP session resumption: allow outer,
664 i.e., not tunneled, EAP-Success to terminate session since; this can
665 be disabled with eap_workaround=0
666 (this was allowed for PEAPv1 before, but now it is also allowed for
667 PEAPv0 since at least one RADIUS authentication server seems to be
668 doing this for PEAPv0, too)
669 * wpa_gui: added preliminary support for adding new networks to the
670 wpa_supplicant configuration (double click on the scan results to
671 open network configuration)
674 * removed interface for external EAPOL/EAP supplicant (e.g.,
675 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
676 anymore and is unlikely to be used by anyone
677 * driver_ndis: fixed WinPcap 3.0 support
678 * fixed build with CONFIG_DNET_PCAP=y on Linux
679 * l2_packet: moved different implementations into separate files
683 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
684 (note: ipw2100-1.1.0 is likely to require an update to work with
686 * added support for using ap_scan=2 mode with multiple network blocks;
687 wpa_supplicant will go through the networks one by one until the
688 driver reports a successful association; this uses the same order for
689 networks as scan_ssid=1 scans, i.e., the priority field is ignored
690 and the network block order in the file is used instead
691 * fixed a potential issue in RSN pre-authentication ending up using
692 freed memory if pre-authentication times out
693 * added support for matching alternative subject name extensions of the
694 authentication server certificate; new configuration variables
695 altsubject_match and altsubject_match2
696 * driver_ndis: added support for IEEE 802.1X authentication with wired
698 * added support for querying private key password (EAP-TLS) through the
699 control interface (wpa_cli/wpa_gui) if one is not included in the
701 * driver_broadcom: fixed couple of memory leaks in scan result
703 * EAP-PAX is now registered as EAP type 46
704 * fixed EAP-PAX MAC calculation
705 * fixed EAP-PAX CK and ICK key derivation
706 * added support for using password with EAP-PAX (as an alternative to
707 entering key with eappsk); SHA-1 hash of the password will be used as
709 * added support for arbitrary driver interface parameters through the
710 configuration file with a new driver_param field; this adds a new
711 driver_ops function set_param()
712 * added possibility to override l2_packet module with driver interface
713 API (new send_eapol handler); this can be used to implement driver
714 specific TX/RX functions for EAPOL frames
715 * fixed ctrl_interface_group processing for the case where gid is
716 entered as a number, not group name
717 * driver_test: added support for testing hostapd with wpa_supplicant
718 by using test driver interface without any kernel drivers or network
722 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
723 packets to be encrypted; this was apparently broken by the changed
724 ioctl order in v0.4.0
725 * driver_madwifi: added preliminary support for compiling against 'BSD'
726 branch of madwifi CVS tree
727 * added support for EAP-MSCHAPv2 password retries within the same EAP
728 authentication session
729 * added support for password changes with EAP-MSCHAPv2 (used when the
730 password has expired)
731 * added support for reading additional certificates from PKCS#12 files
732 and adding them to the certificate chain
733 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
735 * fixed a possible double free in EAP-TTLS fast-reauthentication when
736 identity or password is entered through control interface
737 * display EAP Notification messages to user through control interface
738 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
739 * added GUI version of wpa_cli, wpa_gui; this is not build
740 automatically with 'make'; use 'make wpa_gui' to build (this requires
741 Qt development tools)
742 * added 'disconnect' command to control interface for setting
743 wpa_supplicant in state where it will not associate before
744 'reassociate' command has been used
745 * added support for selecting a network from the list of all configured
746 networks ('wpa_cli select_network <network id>'; this disabled all
747 other networks; to re-enable, 'wpa_cli select_network any')
748 * added support for getting scan results through control interface
749 * added EAP workaround for PEAPv1 session resumption: allow outer,
750 i.e., not tunneled, EAP-Success to terminate session since; this can
751 be disabled with eap_workaround=0
753 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
754 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
755 used to reduce the size of the wpa_supplicant considerably if
756 debugging code is not needed
757 * fixed EAPOL-Key validation to drop packets with invalid Key Data
758 Length; such frames could have crashed wpa_supplicant due to buffer
760 * added support for wired authentication (IEEE 802.1X on wired
761 Ethernet); driver interface 'wired'
762 * obsoleted set_wpa() handler in the driver interface API (it can be
763 replaced by moving enable/disable functionality into init()/deinit())
764 (calls to set_wpa() are still present for backwards compatibility,
765 but they may be removed in the future)
766 * driver_madwifi: fixed association in plaintext mode
767 * modified the EAP workaround that accepts EAP-Success with incorrect
768 Identifier to be even less strict about verification in order to
769 interoperate with some authentication servers
770 * added support for sending TLS alerts
771 * added support for 'any' SSID wildcard; if ssid is not configured or
772 is set to an empty string, any SSID will be accepted for non-WPA AP
773 * added support for asking PIN (for SIM) from frontends (e.g.,
774 wpa_cli); if a PIN is needed, but not included in the configuration
775 file, a control interface request is sent and EAP processing is
776 delayed until the PIN is available
777 * added support for using external devices (e.g., a smartcard) for
778 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
779 new wpa_supplicant.conf variables:
780 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
781 - network: engine, engine_id, key_id
782 * added experimental support for EAP-PAX
783 * added monitor mode for wpa_cli (-a<path to a program to run>) that
784 allows external commands (e.g., shell scripts) to be run based on
785 wpa_supplicant events, e.g., when authentication has been completed
786 and data connection is ready; other related wpa_cli arguments:
787 -B (run in background), -P (write PID file); wpa_supplicant has a new
788 command line argument (-W) that can be used to make it wait until a
789 control interface command is received in order to avoid missing
791 * added support for opportunistic WPA2 PMKSA key caching (disabled by
792 default, can be enabled with proactive_key_caching=1)
793 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
794 Authenticator rejects PMKSA caching attempt and the driver is not
795 using assoc_info events
796 * added -P<pid file> argument for wpa_supplicant to write the current
797 process id into a file
799 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
800 * added new phase1 option parameter, include_tls_length=1, to force
801 wpa_supplicant to add TLS Message Length field to all TLS messages
802 even if the packet is not fragmented; this may be needed with some
803 authentication servers
804 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
805 using drivers that take care of AP selection (e.g., when using
807 * fixed reprocessing of pending request after ctrl_iface requests for
808 identity/password/otp
809 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
810 EAP-PEAP and EAP-TTLS
811 * all drivers using driver_wext: set interface up and select Managed
812 mode when starting wpa_supplicant; set interface down when exiting
813 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
814 ipw2100 and ipw2200; please note that this also changed the
815 configuration variable in .config to CONFIG_DRIVER_IPW
818 * fixed a busy loop introduced in v0.3.5 for scan result processing
819 when no matching AP is found
822 * added a workaround for an interoperability issue with a Cisco AP
824 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
825 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
826 retransmission of dropped frames)
827 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
828 (e.g., segfault when processing EAPOL-Key frames)
829 * fixed EAP workaround and fast reauthentication configuration for
830 RSN pre-authentication; previously these were disabled and
831 pre-authentication would fail if the used authentication server
832 requires EAP workarounds
833 * added support for blacklisting APs that fail or timeout
834 authentication in ap_scan=1 mode so that all APs are tried in cases
835 where the ones with strongest signal level are failing authentication
836 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
837 authentication attempt
838 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
839 in the previous authentication (previously, only Phase 1 success was
843 * added preliminary support for IBSS (ad-hoc) mode configuration
844 (mode=1 in network block); this included a new key_mgmt mode
845 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
846 key management; see wpa_supplicant.conf for more details and an
847 example on how to configure this (note: this is currently implemented
848 only for driver_hostapd.c, but the changes should be trivial to add
849 in associate() handler for other drivers, too (assuming the driver
851 * added preliminary port for native Windows (i.e., no cygwin) using
855 * added optional support for GNU Readline and History Libraries for
856 wpa_cli (CONFIG_READLINE)
857 * cleaned up EAP state machine <-> method interface and number of
858 small problems with error case processing not terminating on
859 EAP-Failure but waiting for timeout
860 * added couple of workarounds for interoperability issues with a
861 Cisco AP when using WPA2
862 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
863 Note: This requires a patch for openssl to add support for TLS
864 extensions and number of workarounds for operations without
865 certificates. Proof of concept type of experimental patch is
866 included in openssl-tls-extensions.patch.
869 * fixed private key loading for cases where passphrase is not set
870 * fixed Windows/cygwin L2 packet handler freeing; previous version
871 could cause a segfault when RSN pre-authentication was completed
872 * added support for PMKSA caching with drivers that generate RSN IEs
873 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
874 but similar code can be easily added to driver_ndiswrapper.c once
875 ndiswrapper gets full support for RSN PMKSA caching
876 * improved recovery from PMKID mismatches by requesting full EAP
877 authentication in case of failed PMKSA caching attempt
878 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
879 (this requires that ndis_events is ran while wpa_supplicant is
881 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
882 * added support for driver interfaces to replace the interface name
883 based on driver/OS specific mapping, e.g., in case of driver_ndis,
884 this allows the beginning of the adapter description to be used as
886 * added support for CR+LF (Windows-style) line ends in configuration
888 * driver_ndis: enable radio before starting scanning, disable radio
890 * modified association event handler to set portEnabled = FALSE before
891 clearing port Valid in order to reset EAP state machine and avoid
892 problems with new authentication getting ignored because of state
893 machines ending up in AUTHENTICATED/SUCCESS state based on old
895 * added support for driver events to add PMKID candidates in order to
896 allow drivers to give priority to most likely roaming candidates
897 * driver_hostap: moved PrivacyInvoked configuration to associate()
898 function so that this will not be set for plaintext connections
899 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
900 interface can distinguish plaintext and IEEE 802.1X (no WPA)
902 * fixed static WEP key configuration to use broadcast/default type for
903 all keys (previously, the default TX key was configured as pairwise/
905 * driver_ndis: added legacy WPA capability detection for non-WPA2
907 * added support for setting static WEP keys for IEEE 802.1X without
908 dynamic WEP keying (eapol_flags=0)
911 * added support for reading PKCS#12 (PFX) files (as a replacement for
912 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
913 * fixed compilation with CONFIG_PCSC=y
914 * added new ap_scan mode, ap_scan=2, for drivers that take care of
915 association, but need to be configured with security policy and SSID,
916 e.g., ndiswrapper and NDIS driver; this mode should allow such
917 drivers to work with hidden SSIDs and optimized roaming; when
918 ap_scan=2 is used, only the first network block in the configuration
919 file is used and this configuration should have explicit security
920 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
921 group, proto variables
922 * added experimental port of wpa_supplicant for Windows
923 - driver_ndis.c driver interface (NDIS OIDs)
924 - currently, this requires cygwin and WinPcap
925 - small utility, win_if_list, can be used to get interface name
926 * control interface can now be removed at build time; add
927 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
928 * optional Xsupplicant interface can now be removed at build time;
929 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
930 * added auth_alg to driver interface associate() parameters to make it
931 easier for drivers to configure authentication algorithm as part of
934 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
935 * driver_broadcom: added new driver interface for Broadcom wl.o driver
936 (a generic driver for Broadcom IEEE 802.11a/g cards)
937 * wpa_cli: fixed parsing of -p <path> command line argument
938 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
939 ACK, not tunneled EAP-Success (of which only the first byte was
940 actually send due to a bug in previous code); this seems to
941 interoperate with most RADIUS servers that implements PEAPv1
942 * PEAPv1: added support for terminating PEAP authentication on tunneled
943 EAP-Success message; this can be configured by adding
944 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
945 (some RADIUS servers require this whereas others require a tunneled
947 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
948 the old label for key derivation; previously, the default was 1,
949 but it looks like most existing PEAPv1 implementations use the old
950 label which is thus more suitable default option
951 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
952 * fixed parsing of wep_tx_keyidx
953 * added support for configuring list of allowed Phase 2 EAP types
954 (for both EAP-PEAP and EAP-TTLS) instead of only one type
955 * added support for configuring IEEE 802.11 authentication algorithm
956 (auth_alg; mainly for using Shared Key authentication with static
958 * added support for EAP-AKA (with UMTS SIM)
959 * fixed couple of errors in PCSC handling that could have caused
960 random-looking errors for EAP-SIM
961 * added support for EAP-SIM pseudonyms and fast re-authentication
962 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
964 * added support for EAP-SIM with two challanges
965 (phase1="sim_min_num_chal=3" can be used to require three challenges)
966 * added support for configuring DH/DSA parameters for an ephemeral DH
967 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
968 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
969 and optional DH key exchange to achieve forward secracy with RSA keys
970 * added support for matching subject of the authentication server
971 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
972 configuration variables subject_match and subject_match2
973 * changed SSID configuration in driver_wext.c (used by many driver
974 interfaces) to use ssid_len+1 as the length for SSID since some Linux
976 * fixed couple of unaligned reads in scan result parsing to fix WPA
977 connection on some platforms (e.g., ARM)
978 * added driver interface for Intel ipw2100 driver
979 * added support for LEAP with WPA
980 * added support for larger scan results report (old limit was 4 kB of
981 data, i.e., about 35 or so APs) when using Linux wireless extensions
983 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
984 only if there is a PMKSA cache entry for the current AP
985 * fixed error handling for case where reading of scan results fails:
986 must schedule a new scan or wpa_supplicant will remain waiting
988 * changed debug output to remove shared password/key material by
989 default; all key information can be included with -K command line
990 argument to match the previous behavior
991 * added support for timestamping debug log messages (disabled by
992 default, can be enabled with -t command line argument)
993 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
994 if keys are not configured to be used; this fixes IEEE 802.1X mode
995 with drivers that use this information to configure whether Privacy
996 bit can be in Beacon frames (e.g., ndiswrapper)
997 * avoid clearing driver keys if no keys have been configured since last
998 key clear request; this seems to improve reliability of group key
999 handshake for ndiswrapper & NDIS driver which seems to be suffering
1000 of some kind of timing issue when the keys are cleared again after
1002 * changed driver interface API:
1003 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
1004 version is being used (now, this is set to 2; previously, it was
1006 - pass pointer to private data structure to all calls
1007 - the new API is not backwards compatible; all in-tree driver
1008 interfaces has been converted to the new API
1009 * added support for controlling multiple interfaces (radios) per
1010 wpa_supplicant process; each interface needs to be listed on the
1011 command line (-c, -i, -D arguments) with -N as a separator
1012 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
1013 * added a workaround for EAP servers that incorrectly use same Id for
1014 sequential EAP packets
1015 * changed libpcap/libdnet configuration to use .config variable,
1016 CONFIG_DNET_PCAP, instead of requiring Makefile modification
1017 * improved downgrade attack detection in IE verification of msg 3/4:
1018 verify both WPA and RSN IEs, if present, not only the selected one;
1019 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
1020 Probe Response frame, and RSN is enabled in wpa_supplicant
1022 * fixed WPA msg 3/4 processing to allow Key Data field contain other
1023 IEs than just one WPA IE
1024 * added support for FreeBSD and driver interface for the BSD net80211
1025 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
1026 required kernel mods have not yet been committed
1027 * made EAP workarounds configurable; enabled by default, can be
1028 disabled with network block option eap_workaround=0
1030 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
1031 * resolved couple of interoperability issues with EAP-PEAPv1 and
1032 Phase 2 (inner EAP) fragment reassembly
1033 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
1034 AP is using non-zero key index for the unicast key and key index zero
1035 for the broadcast key
1036 * driver_hostap: fixed IEEE 802.1X WEP key updates and
1037 re-authentication by allowing unencrypted EAPOL frames when not using
1039 * added a new driver interface, 'wext', which uses only standard,
1040 driver independent functionality in Linux wireless extensions;
1041 currently, this can be used only for non-WPA IEEE 802.1X mode, but
1042 eventually, this is to be extended to support full WPA/WPA2 once
1043 Linux wireless extensions get support for this
1044 * added support for mode in which the driver is responsible for AP
1045 scanning and selection; this is disabled by default and can be
1046 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
1047 this mode can be used, e.g., with generic 'wext' driver interface to
1048 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
1049 supporting wireless extensions.
1050 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
1051 operation with an AP that does not include SSID in the Beacon frames)
1052 * added support for new EAP authentication methods:
1053 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
1054 * added support for asking one-time-passwords from frontends (e.g.,
1055 wpa_cli); this 'otp' command works otherwise like 'password' command,
1056 but the password is used only once and the frontend will be asked for
1057 a new password whenever a request from authenticator requires a
1058 password; this can be used with both EAP-OTP and EAP-GTC
1059 * changed wpa_cli to automatically re-establish connection so that it
1060 does not need to be re-started when wpa_supplicant is terminated and
1062 * improved user data (identity/password/otp) requests through
1063 frontends: process pending EAPOL packets after getting new
1064 information so that full authentication does not need to be
1065 restarted; in addition, send pending requests again whenever a new
1066 frontend is attached
1067 * changed control frontends to use a new directory for socket files to
1068 make it easier for wpa_cli to automatically select between interfaces
1069 and to provide access control for the control interface;
1070 wpa_supplicant.conf: ctrl_interface is now a path
1071 (/var/run/wpa_supplicant is the recommended path) and
1072 ctrl_interface_group can be used to select which group gets access to
1073 the control interface;
1074 wpa_cli: by default, try to connect to the first interface available
1075 in /var/run/wpa_supplicant; this path can be overriden with -p option
1076 and an interface can be selected with -i option (i.e., in most common
1077 cases, wpa_cli does not need to get any arguments)
1078 * added support for LEAP
1079 * added driver interface for Linux ndiswrapper
1080 * added priority option for network blocks in the configuration file;
1081 this allows networks to be grouped based on priority (the scan
1082 results are searched for matches with network blocks in this order)
1085 * sort scan results to improve AP selection
1086 * fixed control interface socket removal for some error cases
1087 * improved scan requesting and authentication timeout
1088 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1090 * PEAP version can now be forced with phase1="peapver=<ver>"
1091 (mostly for testing; by default, the highest version supported by
1092 both the Supplicant and Authentication Server is selected
1094 * added support for madwifi driver (Atheros ar521x)
1095 * added a workaround for cases where AP sets Install Tx/Rx bit for
1096 WPA Group Key messages when pairwise keys are used (without this,
1097 the Group Key would be used for Tx and the AP would drop frames
1099 * added GSM SIM/USIM interface for GSM authentication algorithm for
1100 EAP-SIM; this requires pcsc-lite
1101 * added support for ATMEL AT76C5XXx driver
1102 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1103 does not include key data in the EAPOL-Key frame (i.e., part of
1104 EAP keying material is used as data encryption key)
1105 * added support for using plaintext and static WEP networks
1109 * added support for new EAP authentication methods:
1110 EAP-TTLS/EAP-MD5-Challenge
1112 EAP-TTLS/EAP-MSCHAPv2
1120 EAP-PEAP/MD5-Challenge
1122 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1123 * added support for anonymous identity (to be used when identity is
1124 sent in plaintext; real identity will be used within TLS protected
1125 tunnel (e.g., with EAP-TTLS)
1126 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1127 * added support for requesting identity and password information using
1128 control interface; in other words, the password for EAP-PEAP or
1129 EAP-TTLS does not need to be included in the configuration file since
1130 a frontand (e.g., wpa_cli) can ask it from the user
1131 * improved RSN pre-authentication to use a candidate list and process
1132 all candidates from each scan; not only one per scan
1133 * fixed RSN IE and WPA IE capabilities field parsing
1134 * ignore Tx bit in GTK IE when Pairwise keys are used
1135 * avoid making new scan requests during IEEE 802.1X negotiation
1136 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1137 with TLS support (this replaces the included implementation with
1138 library code to save about 8 kB since the library code is needed
1140 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1141 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1144 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1146 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1147 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1148 - EAP-MD5 (cannot be used with WPA-RADIUS)
1149 [draft-ietf-eap-rfc2284bis-09.txt]
1150 - EAP-TLS [RFC 2716]
1151 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1152 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1153 [draft-kamath-pppext-eap-mschapv2-00.txt]
1154 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1155 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1156 - new configuration file options: eap, identity, password, ca_cert,
1157 client_cert, privatekey, private_key_passwd
1158 - Xsupplicant is not required anymore, but it can be used by
1159 disabling the internal IEEE 802.1X Supplicant with -e command line
1161 - this code is not included in the default build; Makefile need to
1162 be edited for this (uncomment lines for selected functionality)
1163 - EAP-TLS and EAP-PEAP require openssl libraries
1164 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1165 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1166 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1167 EAPOL-Key frames instead of WPA key handshakes)
1168 * added support for IEEE 802.11i/RSN (WPA2)
1169 - improved PTK Key Handshake
1170 - PMKSA caching, pre-authentication
1171 * fixed wpa_supplicant to ignore possible extra data after WPA
1172 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1173 TPTK' error from message 3 of 4-Way Handshake in case the AP
1174 includes extra data after the EAPOL-Key)
1175 * added interface for external programs (frontends) to control
1177 - CLI example (wpa_cli) with interactive mode and command line
1179 - replaced SIGUSR1 status/statistics with the new control interface
1180 * made some feature compile time configurable
1181 - .config file for make
1182 - driver interfaces (hostap, hermes, ..)
1183 - EAPOL/EAP functions
1186 * Initial version of wpa_supplicant
