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)
10 * added support for Wi-Fi Protected Setup (WPS)
11 (wpa_supplicant can now be configured to act as a WPS Enrollee to
12 enroll credentials for a network using PIN and PBC methods; in
13 addition, wpa_supplicant can act as a wireless WPS Registrar to
14 configure an AP); WPS support can be enabled by adding CONFIG_WPS=y
15 into .config and setting the runtime configuration variables in
16 wpa_supplicant.conf (see WPS section in the example configuration
17 file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to
18 manage WPS negotiation; see README-WPS for more details
19 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
20 * added support for using driver_test over UDP socket
21 * fixed PEAPv0 Cryptobinding interoperability issue with Windows Server
22 2008 NPS; optional cryptobinding is now enabled (again) by default
23 * fixed PSK editing in wpa_gui
24 * changed EAP-GPSK to use the IANA assigned EAP method type 51
25 * added a Windows installer that includes WinPcap and all the needed
26 DLLs; in addition, it set up the registry automatically so that user
27 will only need start wpa_gui to get prompted to start the wpasvc
28 servide and add a new interface if needed through wpa_gui dialog
29 * updated management frame protection to use IEEE 802.11w/D7.0
32 * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
33 (can be used to simulate test SIM/USIM card with a known private key;
34 enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
35 and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
36 * added a new network configuration option, wpa_ptk_rekey, that can be
37 used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
38 against TKIP deficiencies
39 * added an optional mitigation mechanism for certain attacks against
40 TKIP by delaying Michael MIC error reports by a random amount of time
41 between 0 and 60 seconds; this can be enabled with a build option
42 CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
43 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
45 * updated OpenSSL code for EAP-FAST to use an updated version of the
46 session ticket overriding API that was included into the upstream
47 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
48 needed with that version anymore)
49 * updated userspace MLME instructions to match with the current Linux
50 mac80211 implementation; please also note that this can only be used
51 with driver_nl80211.c (the old code from driver_wext.c was removed)
52 * added support (Linux only) for RoboSwitch chipsets (often found in
53 consumer grade routers); driver interface 'roboswitch'
54 * fixed canceling of PMKSA caching when using drivers that generate
55 RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
59 * added support for SHA-256 as X.509 certificate digest when using the
60 internal X.509/TLSv1 implementation
61 * updated management frame protection to use IEEE 802.11w/D6.0
62 * added support for using SHA256-based stronger key derivation for WPA2
64 * fixed FT (IEEE 802.11r) authentication after a failed association to
66 * added support for configuring Phase 2 (inner/tunneled) authentication
67 method with wpa_gui-qt4
70 * added support for EAP Sequences in EAP-FAST Phase 2
71 * added support for using TNC with EAP-FAST
72 * added driver_ps3 for the PS3 Linux wireless driver
73 * added support for optional cryptobinding with PEAPv0
74 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
75 allow fallback to full handshake if server rejects PAC-Opaque
76 * added fragmentation support for EAP-TNC
77 * added support for parsing PKCS #8 formatted private keys into the
78 internal TLS implementation (both PKCS #1 RSA key and PKCS #8
79 encapsulated RSA key can now be used)
80 * added option of using faster, but larger, routines in the internal
81 LibTomMath (for internal TLS implementation) to speed up DH and RSA
82 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
83 * fixed race condition between disassociation event and group key
84 handshake to avoid getting stuck in incorrect state [Bug 261]
85 * fixed opportunistic key caching (proactive_key_caching)
88 * removed 'nai' and 'eappsk' network configuration variables that were
89 previously used for configuring user identity and key for EAP-PSK,
90 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
91 replacement for 'nai' (if old configuration used a separate
92 'identity' value, that would now be configured as
93 'anonymous_identity'). 'password' field is now used as the
94 replacement for 'eappsk' (it can also be set using hexstring to
95 present random binary data)
96 * removed '-w' command line parameter (wait for interface to be added,
97 if needed); cleaner way of handling this functionality is to use an
98 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
99 when an interface is added
100 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
101 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
102 indicating when new scan results become available
103 * added new ctrl_iface command, BSS, to allow scan results to be
104 fetched without hitting the message size limits (this command
105 can be used to iterate through the scan results one BSS at the time)
106 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
107 attributes in EAP-SIM Start/Response when using fast reauthentication
108 * fixed EAPOL not to end up in infinite loop when processing dynamic
109 WEP keys with IEEE 802.1X
110 * fixed problems in getting NDIS events from WMI on Windows 2000
113 * added support for Makefile builds to include debug-log-to-a-file
114 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
115 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
116 lengths properly to avoid potential crash caused by invalid messages
117 * added data structure for storing allocated buffers (struct wpabuf);
118 this does not affect wpa_supplicant usage, but many of the APIs
119 changed and various interfaces (e.g., EAP) is not compatible with old
121 * added support for protecting EAP-AKA/Identity messages with
122 AT_CHECKCODE (optional feature in RFC 4187)
123 * added support for protected result indication with AT_RESULT_IND for
124 EAP-SIM and EAP-AKA (phase1="result_ind=1")
125 * added driver_wext workaround for race condition between scanning and
126 association with drivers that take very long time to scan all
127 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
128 using a longer hardcoded timeout for the scan if the driver supports
129 notifications for scan completion (SIOCGIWSCAN event); this helps,
130 e.g., in cases where wpa_supplicant and madwifi driver ended up in
131 loop where the driver did not even try to associate
132 * stop EAPOL timer tick when no timers are in use in order to reduce
133 power consumption (no need to wake up the process once per second)
135 * added support for privilege separation (run only minimal part of
136 wpa_supplicant functionality as root and rest as unprivileged,
137 non-root process); see 'Privilege separation' in README for details;
138 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
140 * changed scan results data structure to include all information
141 elements to make it easier to support new IEs; old get_scan_result()
142 driver_ops is still supported for backwards compatibility (results
143 are converted internally to the new format), but all drivers should
144 start using the new get_scan_results2() to make them more likely to
145 work with new features
146 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
147 application, i.e., it does not require Qt3Support anymore; Windows
148 binary of wpa_gui.exe is now from this directory and only requires
149 QtCore4.dll and QtGui4.dll libraries
150 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
151 available as a separate package to make wpa_gui installation easier:
152 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
153 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
154 only shared key/password authentication is supported in this version
157 * added support for configuring password as NtPasswordHash
158 (16-byte MD4 hash of password) in hash:<32 hex digits> format
159 * added support for fallback from abbreviated TLS handshake to
160 full handshake when using EAP-FAST (e.g., due to an expired
162 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
163 draft (draft-ietf-emu-eap-gpsk-07.txt)
164 * added support for drivers that take care of RSN 4-way handshake
165 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
166 WPA_ALG_PMK in set_key)
167 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
168 .config); this version supports only ap_scan=2 mode and allow the
169 driver to take care of the 4-way handshake
170 * fixed a buffer overflow in parsing TSF from scan results when using
171 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
173 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
174 * fixed an integer overflow issue in the ASN.1 parser used by the
175 (experimental) internal TLS implementation to avoid a potential
177 * fixed a race condition with -W option (wait for a control interface
178 monitor before starting) that could have caused the first messages to
180 * added support for processing TNCC-TNCS-Messages to report
181 recommendation (allow/none/isolate) when using TNC [Bug 243]
184 * added network configuration parameter 'frequency' for setting
185 initial channel for IBSS (adhoc) networks
186 * added experimental IEEE 802.11r/D6.0 support
187 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
188 * updated EAP-PSK to use the IANA-allocated EAP type 47
189 * fixed EAP-PAX key derivation
190 * fixed EAP-PSK bit ordering of the Flags field
191 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
192 tunnelled identity request (previously, the identifier from the outer
193 method was used, not the tunnelled identifier which could be
195 * added support for fragmentation of outer TLS packets during Phase 2
196 of EAP-PEAP/TTLS/FAST
197 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
198 * added support for EAP-FAST authentication with inner methods that
199 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
200 for PAC provisioning)
201 * added support for authenticated EAP-FAST provisioning
202 * added support for configuring maximum number of EAP-FAST PACs to
203 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
204 * added support for storing EAP-FAST PACs in binary format
205 (fast_pac_format=binary in phase1 string)
206 * fixed dbus ctrl_iface to validate message interface before
207 dispatching to avoid a possible segfault [Bug 190]
208 * fixed PeerKey key derivation to use the correct PRF label
209 * updated Windows binary build to link against OpenSSL 0.9.8d and
210 added support for EAP-FAST
211 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
212 draft (draft-ietf-emu-eap-gpsk-04.txt)
213 * fixed EAP-AKA Notification processing to allow Notification to be
214 processed after AKA Challenge response has been sent
215 * updated to use IEEE 802.11w/D2.0 for management frame protection
217 * fixed EAP-TTLS implementation not to crash on use of freed memory
218 if TLS library initialization fails
219 * added support for EAP-TNC (Trusted Network Connect)
220 (this version implements the EAP-TNC method and EAP-TTLS changes
221 needed to run two methods in sequence (IF-T) and the IF-IMC and
222 IF-TNCCS interfaces from TNCC)
225 * added experimental, integrated TLSv1 client implementation with the
226 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
227 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
228 .config); this can be useful, e.g., if the target system does not
229 have a suitable TLS library and a minimal code size is required
230 (total size of this internal TLS/crypto code is bit under 50 kB on
231 x86 and the crypto code is shared by rest of the supplicant so some
232 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
233 * removed STAKey handshake since PeerKey handshake has replaced it in
234 IEEE 802.11ma and there are no known deployments of STAKey
235 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
236 draft (draft-ietf-emu-eap-gpsk-01.txt)
237 * added preliminary implementation of IEEE 802.11w/D1.0 (management
239 (Note: this requires driver support to work properly.)
240 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
241 * fixed Windows named pipes ctrl_iface to not stop listening for
242 commands if client program opens a named pipe and closes it
243 immediately without sending a command
244 * fixed USIM PIN status determination for the case that PIN is not
245 needed (this allows EAP-AKA to be used with USIM cards that do not
247 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
248 be used with cards that do not support file selection based on
250 * added support for matching the subjectAltName of the authentication
251 server certificate against multiple name components (e.g.,
252 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
253 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
254 affects IEEE 802.1X with dynamic WEP keys)
255 * changed ctrl_iface network configuration 'get' operations to not
256 return password/key material; if these fields are requested, "*"
257 will be returned if the password/key is set, but the value of the
258 parameter is not exposed
261 * added support for building Windows version with UNICODE defined
262 (wide-char functions)
263 * driver_ndis: fixed static WEP configuration to avoid race condition
264 issues with some NDIS drivers between association and setting WEP
266 * driver_ndis: added validation for IELength value in scan results to
267 avoid crashes when using buggy NDIS drivers [Bug 165]
268 * fixed Release|Win32 target in the Visual Studio project files
269 (previously, only Debug|Win32 target was set properly)
270 * changed control interface API call wpa_ctrl_pending() to allow it to
271 return -1 on error (e.g., connection lost); control interface clients
272 will need to make sure that they verify that the value is indeed >0
273 when determining whether there are pending messages
274 * added an alternative control interface backend for Windows targets:
275 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
276 control interface mechanism for Windows builds (previously, UDP to
278 * changed ctrl_interface configuration for UNIX domain sockets:
279 - deprecated ctrl_interface_group variable (it may be removed in
281 - allow both directory and group be configured with ctrl_interface
282 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
283 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
284 case when group is not changed
285 * added support for controlling more than one interface per process in
287 * added a workaround for a case where the AP is using unknown address
288 (e.g., MAC address of the wired interface) as the source address for
289 EAPOL-Key frames; previously, that source address was used as the
290 destination for EAPOL-Key frames and in key derivation; now, BSSID is
291 used even if the source address does not match with it
292 (this resolves an interoperability issue with Thomson SpeedTouch 580)
293 * added a workaround for UDP-based control interface (which was used in
294 Windows builds before this release) to prevent packets with forged
295 addresses from being accepted as local control requests
296 * removed ndis_events.cpp and possibility of using external
297 ndis_events.exe; C version (ndis_events.c) is fully functional and
298 there is no desire to maintain two separate versions of this
300 * ndis_events: Changed NDIS event notification design to use WMI to
301 learn the adapter description through Win32_PnPEntity class; this
302 should fix some cases where the adapter name was not recognized
303 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
305 * fixed selection of the first network in ap_scan=2 mode; previously,
306 wpa_supplicant could get stuck in SCANNING state when only the first
307 network for enabled (e.g., after 'wpa_cli select_network 0')
308 * winsvc: added support for configuring ctrl_interface parameters in
309 registry (ctrl_interface string value in
310 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
311 required to enable control interface (previously, this was hardcoded
313 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
314 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
317 * fixed build with CONFIG_STAKEY=y [Bug 143]
318 * added support for doing MLME (IEEE 802.11 management frame
319 processing) in wpa_supplicant when using Devicescape IEEE 802.11
320 stack (wireless-dev.git tree)
321 * added a new network block configuration option, fragment_size, to
322 configure the maximum EAP fragment size
323 * driver_ndis: Disable WZC automatically for the selected interface to
324 avoid conflicts with two programs trying to control the radio; WZC
325 will be re-enabled (if it was enabled originally) when wpa_supplicant
327 * added an experimental TLSv1 client implementation
328 (CONFIG_TLS=internal) that can be used instead of an external TLS
329 library, e.g., to reduce total size requirement on systems that do
330 not include any TLS library by default (this is not yet complete;
331 basic functionality is there, but certificate validation is not yet
333 * added PeerKey handshake implementation for IEEE 802.11e
334 direct link setup (DLS) to replace STAKey handshake
335 * fixed WPA PSK update through ctrl_iface for the case where the old
336 PSK was derived from an ASCII passphrase and the new PSK is set as
337 a raw PSK (hex string)
338 * added new configuration option for identifying which network block
339 was used (id_str in wpa_supplicant.conf; included on
340 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
341 variable in wpa_cli action scripts; in addition WPA_ID variable is
342 set to the current unique identifier that wpa_supplicant assigned
343 automatically for the network and that can be used with
344 GET_NETWORK/SET_NETWORK ctrl_iface commands)
345 * wpa_cli action script is now called only when the connect/disconnect
346 status changes or when associating with a different network
347 * fixed configuration parser not to remove CCMP from group cipher list
348 if WPA-None (adhoc) is used (pairwise=NONE in that case)
349 * fixed integrated NDIS events processing not to hang the process due
350 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
351 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
352 draft-clancy-emu-eap-shared-secret-00.txt)
353 * added Microsoft Visual Studio 2005 solution and project files for
354 build wpa_supplicant for Windows (see vs2005 subdirectory)
355 * eloop_win: fixed unregistration of Windows events
356 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
357 at the end of RSN pre-authentication and added unregistration of
358 a Windows event to avoid getting eloop_win stuck with an invalid
360 * driver_ndis: added support for selecting AP based on BSSID
361 * added new environmental variable for wpa_cli action scripts:
362 WPA_CTRL_DIR is the current control interface directory
363 * driver_ndis: added support for using NDISUIO instead of WinPcap for
364 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
365 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
366 wpa_supplicant without requiring WinPcap; note that using NDISUIO
367 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
368 only one application to open the device
369 * changed NDIS driver naming to only include device GUID, e.g.,
370 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
371 specific \Device\NPF_ prefix before the GUID; the prefix is still
372 allowed for backwards compatibility, but it is not required anymore
373 when specifying the interface
374 * driver_ndis: re-initialize driver interface is the adapter is removed
375 and re-inserted [Bug 159]
376 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
377 big endian hosts [Bug 146]
380 * fixed EAP-GTC response to include correct user identity when run as
381 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
382 * driver_ndis: Fixed encryption mode configuration for unencrypted
383 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
384 refused to associate with open networks) [Bug 106]
385 * driver_ndis: use BSSID OID polling to detect when IBSS network is
386 formed even when ndis_events code is included since some NDIS drivers
387 do not generate media connect events in IBSS mode
388 * config_winreg: allow global ctrl_interface parameter to be configured
390 * config_winreg: added support for saving configuration data into
392 * added support for controlling network device operational state
393 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
394 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
395 that can use this information)
396 * driver_wext: added support for WE-21 change to SSID configuration
397 * driver_wext: fixed privacy configuration for static WEP keys mode
399 * added an optional driver_ops callback for MLME-SETPROTECTION.request
401 * added support for EAP-SAKE (no EAP method number allocated yet, so
402 this is using the same experimental type 255 as EAP-PSK)
403 * added support for dynamically loading EAP methods (.so files) instead
404 of requiring them to be statically linked in; this is disabled by
405 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
409 * do not try to use USIM APDUs when initializing PC/SC for SIM card
410 access for a network that has not enabled EAP-AKA
411 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
412 v0.5.1 due to the new support for expanded EAP types)
413 * added support for generating EAP Expanded Nak
414 * try to fetch scan results once before requesting new scan when
415 starting up in ap_scan=1 mode (this can speed up initial association
416 a lot with, e.g., madwifi-ng driver)
417 * added support for receiving EAPOL frames from a Linux bridge
418 interface (-bbr0 on command line)
419 * fixed EAPOL re-authentication for sessions that used PMKSA caching
420 * changed EAP method registration to use a dynamic list of methods
421 instead of a static list generated at build time
422 * fixed PMKSA cache deinitialization not to use freed memory when
423 removing PMKSA entries
424 * fixed a memory leak in EAP-TTLS re-authentication
425 * reject WPA/WPA2 message 3/4 if it does not include any valid
427 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
428 if the driver does not support SIOCSIWAUTH
431 * driver_test: added better support for multiple APs and STAs by using
432 a directory with sockets that include MAC address for each device in
433 the name (driver_param=test_dir=/tmp/test)
434 * added support for EAP expanded type (vendor specific EAP methods)
435 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
436 option can be changed if needed
437 * wpa_cli/wpa_gui: skip non-socket files in control directory when
438 using UNIX domain sockets; this avoids selecting an incorrect
439 interface (e.g., a PID file could be in this directory, even though
440 use of this directory for something else than socket files is not
442 * fixed TLS library deinitialization after RSN pre-authentication not
443 to disable TLS library for normal authentication
444 * driver_wext: Remove null-termination from SSID length if the driver
445 used it; some Linux drivers do this and they were causing problems in
446 wpa_supplicant not finding matching configuration block. This change
447 would break a case where the SSID actually ends in '\0', but that is
448 not likely to happen in real use.
449 * fixed PMKSA cache processing not to trigger deauthentication if the
450 current PMKSA cache entry is replaced with a valid new entry
451 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
452 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
455 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
456 * added experimental STAKey handshake implementation for IEEE 802.11e
457 direct link setup (DLS); note: this is disabled by default in both
458 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
460 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
461 decrypt AT_ENCR_DATA attributes correctly
462 * fixed EAP-AKA to allow resynchronization within the same session
463 * made code closer to ANSI C89 standard to make it easier to port to
464 other C libraries and compilers
465 * started moving operating system or C library specific functions into
466 wrapper functions defined in os.h and implemented in os_*.c to make
468 * wpa_supplicant can now be built with Microsoft Visual C++
469 (e.g., with the freely available Toolkit 2003 version or Visual
470 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
471 example makefile for nmake
472 * added support for using Windows registry for command line parameters
473 (CONFIG_MAIN=main_winsvc) and configuration data
474 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
475 contents; this version can be run both as a Windows service and as a
476 normal application; 'wpasvc.exe app' to start as applicant,
477 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
478 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
480 * made it possible to link ndis_events.exe functionality into
481 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
482 * added better support for multiple control interface backends
483 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
484 * fixed PC/SC code to use correct length for GSM AUTH command buffer
485 and to not use pioRecvPci with SCardTransmit() calls; these were not
486 causing visible problems with pcsc-lite, but Windows Winscard.dll
487 refused the previously used parameters; this fixes EAP-SIM and
488 EAP-AKA authentication using SIM/USIM card under Windows
489 * added new event loop implementation for Windows using
490 WaitForMultipleObject() instead of select() in order to allow waiting
491 for non-socket objects; this can be selected with
492 CONFIG_ELOOP=eloop_win in .config
493 * added support for selecting l2_packet implementation in .config
494 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
495 winpcap, freebsd, none)
496 * added new l2_packet implementation for WinPcap
497 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
498 reduce latency in EAPOL receive processing from about 100 ms to about
500 * added support for EAP-FAST key derivation using other ciphers than
501 RC4-128-SHA for authentication and AES128-SHA for provisioning
502 * added support for configuring CA certificate as DER file and as a
504 * fixed private key configuration as configuration blob and added
505 support for using PKCS#12 as a blob
506 * tls_gnutls: added support for using PKCS#12 files; added support for
508 * added support for loading trusted CA certificates from Windows
509 certificate store: ca_cert="cert_store://<name>", where <name> is
510 likely CA (Intermediate CA certificates) or ROOT (root certificates)
511 * added C version of ndis_events.cpp and made it possible to build this
512 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
513 easily on cross-compilation builds
514 * added wpasvc.exe into Windows binary release; this is an alternative
515 version of wpa_supplicant.exe with configuration backend using
516 Windows registry and with the entry point designed to run as a
518 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
519 wpasvc.exe and removed this additional tool from the Windows binary
520 release since it is not needed anymore
521 * load winscard.dll functions dynamically when building with MinGW
522 since MinGW does not yet include winscard library
524 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
525 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
526 and WinPcap to receive frames sent to PAE group address
527 * disable EAP state machine when IEEE 802.1X authentication is not used
528 in order to get rid of bogus "EAP failed" messages
529 * fixed OpenSSL error reporting to go through all pending errors to
530 avoid confusing reports of old errors being reported at later point
532 * fixed configuration file updating to not write empty variables
533 (e.g., proto or key_mgmt) that the file parser would not accept
534 * fixed ADD_NETWORK ctrl_iface command to use the same default values
535 for variables as empty network definitions read from config file
537 * fixed EAP state machine to not discard EAP-Failure messages in many
538 cases (e.g., during TLS handshake)
539 * fixed a infinite loop in private key reading if the configured file
540 cannot be parsed successfully
541 * driver_madwifi: added support for madwifi-ng
542 * wpa_gui: do not display password/PSK field contents
543 * wpa_gui: added CA certificate configuration
544 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
545 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
546 the new AP is using different WPA/RSN IE
547 * use longer timeout for IEEE 802.11 association to avoid problems with
548 drivers that may take more than five second to associate
551 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
552 RSN IE, but WPA IE would match with wpa_supplicant configuration
553 * added support for named configuration blobs in order to avoid having
554 to use file system for external files (e.g., certificates);
555 variables can be set to "blob://<blob name>" instead of file path to
556 use a named blob; supported fields: pac_file, client_cert,
558 * fixed RSN pre-authentication (it was broken in the clean up of WPA
559 state machine interface in v0.4.5)
560 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
561 sure the driver configures broadcast decryption correctly
562 * added ca_path (and ca_path2) configuration variables that can be used
563 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
564 system-wide trusted CA list
565 * added support for starting wpa_supplicant without a configuration
566 file (-C argument must be used to set ctrl_interface parameter for
567 this case; in addition, -p argument can be used to provide
568 driver_param; these new arguments can also be used with a
569 configuration to override the values from the configuration)
570 * added global control interface that can be optionally used for adding
571 and removing network interfaces dynamically (-g command line argument
572 for both wpa_supplicant and wpa_cli) without having to restart
573 wpa_supplicant process
575 - try to save configuration whenever something is modified
576 - added WEP key configuration
577 - added possibility to edit the current network configuration
578 * driver_ndis: fixed driver polling not to increase frequency on each
579 received EAPOL frame due to incorrectly cancelled timeout
580 * added simple configuration file examples (in examples subdirectory)
581 * fixed driver_wext.c to filter wireless events based on ifindex to
582 avoid interfaces receiving events from other interfaces
583 * delay sending initial EAPOL-Start couple of seconds to speed up
584 authentication for the most common case of Authenticator starting
585 EAP authentication immediately after association
588 * added a workaround for clearing keys with ndiswrapper to allow
589 roaming from WPA enabled AP to plaintext one
590 * added docbook documentation (doc/docbook) that can be used to
591 generate, e.g., man pages
592 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
593 PF_PACKET in order to prepare for network devices that do not use
594 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
595 * use receipt of EAPOL-Key frame as a lower layer success indication
596 for EAP state machine to allow recovery from dropped EAP-Success
598 * cleaned up internal EAPOL frame processing by not including link
599 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
600 header is added only when transmitted the frame; this makes it easier
601 to use wpa_supplicant on link layers that use different header than
603 * updated EAP-PSK to use draft 9 by default since this can now be
604 tested with hostapd; removed support for draft 3, including
605 server_nai configuration option from network blocks
606 * driver_wired: add PAE address to the multicast address list in order
607 to be able to receive EAPOL frames with drivers that do not include
608 these multicast addresses by default
609 * driver_wext: add support for WE-19
610 * added support for multiple configuration backends (CONFIG_BACKEND
611 option); currently, only 'file' is supported (i.e., the format used
612 in wpa_supplicant.conf)
613 * added support for updating configuration ('wpa_cli save_config');
614 this is disabled by default and can be enabled with global
615 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
616 and wpa_gui to store the configuration changes in a permanent store
617 * added GET_NETWORK ctrl_iface command
618 (e.g., 'wpa_cli get_network 0 ssid')
621 * replaced OpenSSL patch for EAP-FAST support
622 (openssl-tls-extensions.patch) with a more generic and correct
623 patch (the new patch is not compatible with the previous one, so the
624 OpenSSL library will need to be patched with the new patch in order
625 to be able to build wpa_supplicant with EAP-FAST support)
626 * added support for using Windows certificate store (through CryptoAPI)
627 for client certificate and private key operations (EAP-TLS)
628 (see wpa_supplicant.conf for more information on how to configure
629 this with private_key)
630 * ported wpa_gui to Windows
631 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
632 built with the open source version of the Qt4 for Windows
633 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
634 with drivers that do not support WPA
635 * ndis_events: fixed Windows 2000 support
636 * added support for enabling/disabling networks from the list of all
637 configured networks ('wpa_cli enable_network <network id>' and
638 'wpa_cli disable_network <network id>')
639 * added support for adding and removing network from the current
640 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
641 <network id>'); added networks are disabled by default and they can
642 be enabled with enable_network command once the configuration is done
643 for the new network; note: configuration file is not yet updated, so
644 these new networks are lost when wpa_supplicant is restarted
645 * added support for setting network configuration parameters through
646 the control interface, for example:
647 wpa_cli set_network 0 ssid "\"my network\""
648 * fixed parsing of strings that include both " and # within double
649 quoted area (e.g., "start"#end")
650 * added EAP workaround for PEAP session resumption: allow outer,
651 i.e., not tunneled, EAP-Success to terminate session since; this can
652 be disabled with eap_workaround=0
653 (this was allowed for PEAPv1 before, but now it is also allowed for
654 PEAPv0 since at least one RADIUS authentication server seems to be
655 doing this for PEAPv0, too)
656 * wpa_gui: added preliminary support for adding new networks to the
657 wpa_supplicant configuration (double click on the scan results to
658 open network configuration)
661 * removed interface for external EAPOL/EAP supplicant (e.g.,
662 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
663 anymore and is unlikely to be used by anyone
664 * driver_ndis: fixed WinPcap 3.0 support
665 * fixed build with CONFIG_DNET_PCAP=y on Linux
666 * l2_packet: moved different implementations into separate files
670 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
671 (note: ipw2100-1.1.0 is likely to require an update to work with
673 * added support for using ap_scan=2 mode with multiple network blocks;
674 wpa_supplicant will go through the networks one by one until the
675 driver reports a successful association; this uses the same order for
676 networks as scan_ssid=1 scans, i.e., the priority field is ignored
677 and the network block order in the file is used instead
678 * fixed a potential issue in RSN pre-authentication ending up using
679 freed memory if pre-authentication times out
680 * added support for matching alternative subject name extensions of the
681 authentication server certificate; new configuration variables
682 altsubject_match and altsubject_match2
683 * driver_ndis: added support for IEEE 802.1X authentication with wired
685 * added support for querying private key password (EAP-TLS) through the
686 control interface (wpa_cli/wpa_gui) if one is not included in the
688 * driver_broadcom: fixed couple of memory leaks in scan result
690 * EAP-PAX is now registered as EAP type 46
691 * fixed EAP-PAX MAC calculation
692 * fixed EAP-PAX CK and ICK key derivation
693 * added support for using password with EAP-PAX (as an alternative to
694 entering key with eappsk); SHA-1 hash of the password will be used as
696 * added support for arbitrary driver interface parameters through the
697 configuration file with a new driver_param field; this adds a new
698 driver_ops function set_param()
699 * added possibility to override l2_packet module with driver interface
700 API (new send_eapol handler); this can be used to implement driver
701 specific TX/RX functions for EAPOL frames
702 * fixed ctrl_interface_group processing for the case where gid is
703 entered as a number, not group name
704 * driver_test: added support for testing hostapd with wpa_supplicant
705 by using test driver interface without any kernel drivers or network
709 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
710 packets to be encrypted; this was apparently broken by the changed
711 ioctl order in v0.4.0
712 * driver_madwifi: added preliminary support for compiling against 'BSD'
713 branch of madwifi CVS tree
714 * added support for EAP-MSCHAPv2 password retries within the same EAP
715 authentication session
716 * added support for password changes with EAP-MSCHAPv2 (used when the
717 password has expired)
718 * added support for reading additional certificates from PKCS#12 files
719 and adding them to the certificate chain
720 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
722 * fixed a possible double free in EAP-TTLS fast-reauthentication when
723 identity or password is entered through control interface
724 * display EAP Notification messages to user through control interface
725 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
726 * added GUI version of wpa_cli, wpa_gui; this is not build
727 automatically with 'make'; use 'make wpa_gui' to build (this requires
728 Qt development tools)
729 * added 'disconnect' command to control interface for setting
730 wpa_supplicant in state where it will not associate before
731 'reassociate' command has been used
732 * added support for selecting a network from the list of all configured
733 networks ('wpa_cli select_network <network id>'; this disabled all
734 other networks; to re-enable, 'wpa_cli select_network any')
735 * added support for getting scan results through control interface
736 * added EAP workaround for PEAPv1 session resumption: allow outer,
737 i.e., not tunneled, EAP-Success to terminate session since; this can
738 be disabled with eap_workaround=0
740 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
741 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
742 used to reduce the size of the wpa_supplicant considerably if
743 debugging code is not needed
744 * fixed EAPOL-Key validation to drop packets with invalid Key Data
745 Length; such frames could have crashed wpa_supplicant due to buffer
747 * added support for wired authentication (IEEE 802.1X on wired
748 Ethernet); driver interface 'wired'
749 * obsoleted set_wpa() handler in the driver interface API (it can be
750 replaced by moving enable/disable functionality into init()/deinit())
751 (calls to set_wpa() are still present for backwards compatibility,
752 but they may be removed in the future)
753 * driver_madwifi: fixed association in plaintext mode
754 * modified the EAP workaround that accepts EAP-Success with incorrect
755 Identifier to be even less strict about verification in order to
756 interoperate with some authentication servers
757 * added support for sending TLS alerts
758 * added support for 'any' SSID wildcard; if ssid is not configured or
759 is set to an empty string, any SSID will be accepted for non-WPA AP
760 * added support for asking PIN (for SIM) from frontends (e.g.,
761 wpa_cli); if a PIN is needed, but not included in the configuration
762 file, a control interface request is sent and EAP processing is
763 delayed until the PIN is available
764 * added support for using external devices (e.g., a smartcard) for
765 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
766 new wpa_supplicant.conf variables:
767 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
768 - network: engine, engine_id, key_id
769 * added experimental support for EAP-PAX
770 * added monitor mode for wpa_cli (-a<path to a program to run>) that
771 allows external commands (e.g., shell scripts) to be run based on
772 wpa_supplicant events, e.g., when authentication has been completed
773 and data connection is ready; other related wpa_cli arguments:
774 -B (run in background), -P (write PID file); wpa_supplicant has a new
775 command line argument (-W) that can be used to make it wait until a
776 control interface command is received in order to avoid missing
778 * added support for opportunistic WPA2 PMKSA key caching (disabled by
779 default, can be enabled with proactive_key_caching=1)
780 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
781 Authenticator rejects PMKSA caching attempt and the driver is not
782 using assoc_info events
783 * added -P<pid file> argument for wpa_supplicant to write the current
784 process id into a file
786 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
787 * added new phase1 option parameter, include_tls_length=1, to force
788 wpa_supplicant to add TLS Message Length field to all TLS messages
789 even if the packet is not fragmented; this may be needed with some
790 authentication servers
791 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
792 using drivers that take care of AP selection (e.g., when using
794 * fixed reprocessing of pending request after ctrl_iface requests for
795 identity/password/otp
796 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
797 EAP-PEAP and EAP-TTLS
798 * all drivers using driver_wext: set interface up and select Managed
799 mode when starting wpa_supplicant; set interface down when exiting
800 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
801 ipw2100 and ipw2200; please note that this also changed the
802 configuration variable in .config to CONFIG_DRIVER_IPW
805 * fixed a busy loop introduced in v0.3.5 for scan result processing
806 when no matching AP is found
809 * added a workaround for an interoperability issue with a Cisco AP
811 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
812 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
813 retransmission of dropped frames)
814 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
815 (e.g., segfault when processing EAPOL-Key frames)
816 * fixed EAP workaround and fast reauthentication configuration for
817 RSN pre-authentication; previously these were disabled and
818 pre-authentication would fail if the used authentication server
819 requires EAP workarounds
820 * added support for blacklisting APs that fail or timeout
821 authentication in ap_scan=1 mode so that all APs are tried in cases
822 where the ones with strongest signal level are failing authentication
823 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
824 authentication attempt
825 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
826 in the previous authentication (previously, only Phase 1 success was
830 * added preliminary support for IBSS (ad-hoc) mode configuration
831 (mode=1 in network block); this included a new key_mgmt mode
832 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
833 key management; see wpa_supplicant.conf for more details and an
834 example on how to configure this (note: this is currently implemented
835 only for driver_hostapd.c, but the changes should be trivial to add
836 in associate() handler for other drivers, too (assuming the driver
838 * added preliminary port for native Windows (i.e., no cygwin) using
842 * added optional support for GNU Readline and History Libraries for
843 wpa_cli (CONFIG_READLINE)
844 * cleaned up EAP state machine <-> method interface and number of
845 small problems with error case processing not terminating on
846 EAP-Failure but waiting for timeout
847 * added couple of workarounds for interoperability issues with a
848 Cisco AP when using WPA2
849 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
850 Note: This requires a patch for openssl to add support for TLS
851 extensions and number of workarounds for operations without
852 certificates. Proof of concept type of experimental patch is
853 included in openssl-tls-extensions.patch.
856 * fixed private key loading for cases where passphrase is not set
857 * fixed Windows/cygwin L2 packet handler freeing; previous version
858 could cause a segfault when RSN pre-authentication was completed
859 * added support for PMKSA caching with drivers that generate RSN IEs
860 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
861 but similar code can be easily added to driver_ndiswrapper.c once
862 ndiswrapper gets full support for RSN PMKSA caching
863 * improved recovery from PMKID mismatches by requesting full EAP
864 authentication in case of failed PMKSA caching attempt
865 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
866 (this requires that ndis_events is ran while wpa_supplicant is
868 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
869 * added support for driver interfaces to replace the interface name
870 based on driver/OS specific mapping, e.g., in case of driver_ndis,
871 this allows the beginning of the adapter description to be used as
873 * added support for CR+LF (Windows-style) line ends in configuration
875 * driver_ndis: enable radio before starting scanning, disable radio
877 * modified association event handler to set portEnabled = FALSE before
878 clearing port Valid in order to reset EAP state machine and avoid
879 problems with new authentication getting ignored because of state
880 machines ending up in AUTHENTICATED/SUCCESS state based on old
882 * added support for driver events to add PMKID candidates in order to
883 allow drivers to give priority to most likely roaming candidates
884 * driver_hostap: moved PrivacyInvoked configuration to associate()
885 function so that this will not be set for plaintext connections
886 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
887 interface can distinguish plaintext and IEEE 802.1X (no WPA)
889 * fixed static WEP key configuration to use broadcast/default type for
890 all keys (previously, the default TX key was configured as pairwise/
892 * driver_ndis: added legacy WPA capability detection for non-WPA2
894 * added support for setting static WEP keys for IEEE 802.1X without
895 dynamic WEP keying (eapol_flags=0)
898 * added support for reading PKCS#12 (PFX) files (as a replacement for
899 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
900 * fixed compilation with CONFIG_PCSC=y
901 * added new ap_scan mode, ap_scan=2, for drivers that take care of
902 association, but need to be configured with security policy and SSID,
903 e.g., ndiswrapper and NDIS driver; this mode should allow such
904 drivers to work with hidden SSIDs and optimized roaming; when
905 ap_scan=2 is used, only the first network block in the configuration
906 file is used and this configuration should have explicit security
907 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
908 group, proto variables
909 * added experimental port of wpa_supplicant for Windows
910 - driver_ndis.c driver interface (NDIS OIDs)
911 - currently, this requires cygwin and WinPcap
912 - small utility, win_if_list, can be used to get interface name
913 * control interface can now be removed at build time; add
914 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
915 * optional Xsupplicant interface can now be removed at build time;
916 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
917 * added auth_alg to driver interface associate() parameters to make it
918 easier for drivers to configure authentication algorithm as part of
921 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
922 * driver_broadcom: added new driver interface for Broadcom wl.o driver
923 (a generic driver for Broadcom IEEE 802.11a/g cards)
924 * wpa_cli: fixed parsing of -p <path> command line argument
925 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
926 ACK, not tunneled EAP-Success (of which only the first byte was
927 actually send due to a bug in previous code); this seems to
928 interoperate with most RADIUS servers that implements PEAPv1
929 * PEAPv1: added support for terminating PEAP authentication on tunneled
930 EAP-Success message; this can be configured by adding
931 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
932 (some RADIUS servers require this whereas others require a tunneled
934 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
935 the old label for key derivation; previously, the default was 1,
936 but it looks like most existing PEAPv1 implementations use the old
937 label which is thus more suitable default option
938 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
939 * fixed parsing of wep_tx_keyidx
940 * added support for configuring list of allowed Phase 2 EAP types
941 (for both EAP-PEAP and EAP-TTLS) instead of only one type
942 * added support for configuring IEEE 802.11 authentication algorithm
943 (auth_alg; mainly for using Shared Key authentication with static
945 * added support for EAP-AKA (with UMTS SIM)
946 * fixed couple of errors in PCSC handling that could have caused
947 random-looking errors for EAP-SIM
948 * added support for EAP-SIM pseudonyms and fast re-authentication
949 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
951 * added support for EAP-SIM with two challanges
952 (phase1="sim_min_num_chal=3" can be used to require three challenges)
953 * added support for configuring DH/DSA parameters for an ephemeral DH
954 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
955 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
956 and optional DH key exchange to achieve forward secracy with RSA keys
957 * added support for matching subject of the authentication server
958 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
959 configuration variables subject_match and subject_match2
960 * changed SSID configuration in driver_wext.c (used by many driver
961 interfaces) to use ssid_len+1 as the length for SSID since some Linux
963 * fixed couple of unaligned reads in scan result parsing to fix WPA
964 connection on some platforms (e.g., ARM)
965 * added driver interface for Intel ipw2100 driver
966 * added support for LEAP with WPA
967 * added support for larger scan results report (old limit was 4 kB of
968 data, i.e., about 35 or so APs) when using Linux wireless extensions
970 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
971 only if there is a PMKSA cache entry for the current AP
972 * fixed error handling for case where reading of scan results fails:
973 must schedule a new scan or wpa_supplicant will remain waiting
975 * changed debug output to remove shared password/key material by
976 default; all key information can be included with -K command line
977 argument to match the previous behavior
978 * added support for timestamping debug log messages (disabled by
979 default, can be enabled with -t command line argument)
980 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
981 if keys are not configured to be used; this fixes IEEE 802.1X mode
982 with drivers that use this information to configure whether Privacy
983 bit can be in Beacon frames (e.g., ndiswrapper)
984 * avoid clearing driver keys if no keys have been configured since last
985 key clear request; this seems to improve reliability of group key
986 handshake for ndiswrapper & NDIS driver which seems to be suffering
987 of some kind of timing issue when the keys are cleared again after
989 * changed driver interface API:
990 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
991 version is being used (now, this is set to 2; previously, it was
993 - pass pointer to private data structure to all calls
994 - the new API is not backwards compatible; all in-tree driver
995 interfaces has been converted to the new API
996 * added support for controlling multiple interfaces (radios) per
997 wpa_supplicant process; each interface needs to be listed on the
998 command line (-c, -i, -D arguments) with -N as a separator
999 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
1000 * added a workaround for EAP servers that incorrectly use same Id for
1001 sequential EAP packets
1002 * changed libpcap/libdnet configuration to use .config variable,
1003 CONFIG_DNET_PCAP, instead of requiring Makefile modification
1004 * improved downgrade attack detection in IE verification of msg 3/4:
1005 verify both WPA and RSN IEs, if present, not only the selected one;
1006 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
1007 Probe Response frame, and RSN is enabled in wpa_supplicant
1009 * fixed WPA msg 3/4 processing to allow Key Data field contain other
1010 IEs than just one WPA IE
1011 * added support for FreeBSD and driver interface for the BSD net80211
1012 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
1013 required kernel mods have not yet been committed
1014 * made EAP workarounds configurable; enabled by default, can be
1015 disabled with network block option eap_workaround=0
1017 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
1018 * resolved couple of interoperability issues with EAP-PEAPv1 and
1019 Phase 2 (inner EAP) fragment reassembly
1020 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
1021 AP is using non-zero key index for the unicast key and key index zero
1022 for the broadcast key
1023 * driver_hostap: fixed IEEE 802.1X WEP key updates and
1024 re-authentication by allowing unencrypted EAPOL frames when not using
1026 * added a new driver interface, 'wext', which uses only standard,
1027 driver independent functionality in Linux wireless extensions;
1028 currently, this can be used only for non-WPA IEEE 802.1X mode, but
1029 eventually, this is to be extended to support full WPA/WPA2 once
1030 Linux wireless extensions get support for this
1031 * added support for mode in which the driver is responsible for AP
1032 scanning and selection; this is disabled by default and can be
1033 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
1034 this mode can be used, e.g., with generic 'wext' driver interface to
1035 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
1036 supporting wireless extensions.
1037 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
1038 operation with an AP that does not include SSID in the Beacon frames)
1039 * added support for new EAP authentication methods:
1040 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
1041 * added support for asking one-time-passwords from frontends (e.g.,
1042 wpa_cli); this 'otp' command works otherwise like 'password' command,
1043 but the password is used only once and the frontend will be asked for
1044 a new password whenever a request from authenticator requires a
1045 password; this can be used with both EAP-OTP and EAP-GTC
1046 * changed wpa_cli to automatically re-establish connection so that it
1047 does not need to be re-started when wpa_supplicant is terminated and
1049 * improved user data (identity/password/otp) requests through
1050 frontends: process pending EAPOL packets after getting new
1051 information so that full authentication does not need to be
1052 restarted; in addition, send pending requests again whenever a new
1053 frontend is attached
1054 * changed control frontends to use a new directory for socket files to
1055 make it easier for wpa_cli to automatically select between interfaces
1056 and to provide access control for the control interface;
1057 wpa_supplicant.conf: ctrl_interface is now a path
1058 (/var/run/wpa_supplicant is the recommended path) and
1059 ctrl_interface_group can be used to select which group gets access to
1060 the control interface;
1061 wpa_cli: by default, try to connect to the first interface available
1062 in /var/run/wpa_supplicant; this path can be overriden with -p option
1063 and an interface can be selected with -i option (i.e., in most common
1064 cases, wpa_cli does not need to get any arguments)
1065 * added support for LEAP
1066 * added driver interface for Linux ndiswrapper
1067 * added priority option for network blocks in the configuration file;
1068 this allows networks to be grouped based on priority (the scan
1069 results are searched for matches with network blocks in this order)
1072 * sort scan results to improve AP selection
1073 * fixed control interface socket removal for some error cases
1074 * improved scan requesting and authentication timeout
1075 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1077 * PEAP version can now be forced with phase1="peapver=<ver>"
1078 (mostly for testing; by default, the highest version supported by
1079 both the Supplicant and Authentication Server is selected
1081 * added support for madwifi driver (Atheros ar521x)
1082 * added a workaround for cases where AP sets Install Tx/Rx bit for
1083 WPA Group Key messages when pairwise keys are used (without this,
1084 the Group Key would be used for Tx and the AP would drop frames
1086 * added GSM SIM/USIM interface for GSM authentication algorithm for
1087 EAP-SIM; this requires pcsc-lite
1088 * added support for ATMEL AT76C5XXx driver
1089 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1090 does not include key data in the EAPOL-Key frame (i.e., part of
1091 EAP keying material is used as data encryption key)
1092 * added support for using plaintext and static WEP networks
1096 * added support for new EAP authentication methods:
1097 EAP-TTLS/EAP-MD5-Challenge
1099 EAP-TTLS/EAP-MSCHAPv2
1107 EAP-PEAP/MD5-Challenge
1109 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1110 * added support for anonymous identity (to be used when identity is
1111 sent in plaintext; real identity will be used within TLS protected
1112 tunnel (e.g., with EAP-TTLS)
1113 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1114 * added support for requesting identity and password information using
1115 control interface; in other words, the password for EAP-PEAP or
1116 EAP-TTLS does not need to be included in the configuration file since
1117 a frontand (e.g., wpa_cli) can ask it from the user
1118 * improved RSN pre-authentication to use a candidate list and process
1119 all candidates from each scan; not only one per scan
1120 * fixed RSN IE and WPA IE capabilities field parsing
1121 * ignore Tx bit in GTK IE when Pairwise keys are used
1122 * avoid making new scan requests during IEEE 802.1X negotiation
1123 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1124 with TLS support (this replaces the included implementation with
1125 library code to save about 8 kB since the library code is needed
1127 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1128 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1131 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1133 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1134 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1135 - EAP-MD5 (cannot be used with WPA-RADIUS)
1136 [draft-ietf-eap-rfc2284bis-09.txt]
1137 - EAP-TLS [RFC 2716]
1138 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1139 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1140 [draft-kamath-pppext-eap-mschapv2-00.txt]
1141 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1142 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1143 - new configuration file options: eap, identity, password, ca_cert,
1144 client_cert, privatekey, private_key_passwd
1145 - Xsupplicant is not required anymore, but it can be used by
1146 disabling the internal IEEE 802.1X Supplicant with -e command line
1148 - this code is not included in the default build; Makefile need to
1149 be edited for this (uncomment lines for selected functionality)
1150 - EAP-TLS and EAP-PEAP require openssl libraries
1151 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1152 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1153 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1154 EAPOL-Key frames instead of WPA key handshakes)
1155 * added support for IEEE 802.11i/RSN (WPA2)
1156 - improved PTK Key Handshake
1157 - PMKSA caching, pre-authentication
1158 * fixed wpa_supplicant to ignore possible extra data after WPA
1159 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1160 TPTK' error from message 3 of 4-Way Handshake in case the AP
1161 includes extra data after the EAPOL-Key)
1162 * added interface for external programs (frontends) to control
1164 - CLI example (wpa_cli) with interactive mode and command line
1166 - replaced SIGUSR1 status/statistics with the new control interface
1167 * made some feature compile time configurable
1168 - .config file for make
1169 - driver interfaces (hostap, hermes, ..)
1170 - EAPOL/EAP functions
1173 * Initial version of wpa_supplicant
