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]
21 * added better support for drivers that allow separate authentication
22 and association commands (e.g., mac80211-based Linux drivers with
23 nl80211; SME in wpa_supplicant); this allows over-the-air FT protocol
24 to be used (IEEE 802.11r)
27 * added support for Wi-Fi Protected Setup (WPS)
28 (wpa_supplicant can now be configured to act as a WPS Enrollee to
29 enroll credentials for a network using PIN and PBC methods; in
30 addition, wpa_supplicant can act as a wireless WPS Registrar to
31 configure an AP); WPS support can be enabled by adding CONFIG_WPS=y
32 into .config and setting the runtime configuration variables in
33 wpa_supplicant.conf (see WPS section in the example configuration
34 file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to
35 manage WPS negotiation; see README-WPS for more details
36 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
37 * added support for using driver_test over UDP socket
38 * fixed PEAPv0 Cryptobinding interoperability issue with Windows Server
39 2008 NPS; optional cryptobinding is now enabled (again) by default
40 * fixed PSK editing in wpa_gui
41 * changed EAP-GPSK to use the IANA assigned EAP method type 51
42 * added a Windows installer that includes WinPcap and all the needed
43 DLLs; in addition, it set up the registry automatically so that user
44 will only need start wpa_gui to get prompted to start the wpasvc
45 servide and add a new interface if needed through wpa_gui dialog
46 * updated management frame protection to use IEEE 802.11w/D7.0
49 * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
50 (can be used to simulate test SIM/USIM card with a known private key;
51 enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
52 and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
53 * added a new network configuration option, wpa_ptk_rekey, that can be
54 used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
55 against TKIP deficiencies
56 * added an optional mitigation mechanism for certain attacks against
57 TKIP by delaying Michael MIC error reports by a random amount of time
58 between 0 and 60 seconds; this can be enabled with a build option
59 CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
60 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
62 * updated OpenSSL code for EAP-FAST to use an updated version of the
63 session ticket overriding API that was included into the upstream
64 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
65 needed with that version anymore)
66 * updated userspace MLME instructions to match with the current Linux
67 mac80211 implementation; please also note that this can only be used
68 with driver_nl80211.c (the old code from driver_wext.c was removed)
69 * added support (Linux only) for RoboSwitch chipsets (often found in
70 consumer grade routers); driver interface 'roboswitch'
71 * fixed canceling of PMKSA caching when using drivers that generate
72 RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
76 * added support for SHA-256 as X.509 certificate digest when using the
77 internal X.509/TLSv1 implementation
78 * updated management frame protection to use IEEE 802.11w/D6.0
79 * added support for using SHA256-based stronger key derivation for WPA2
81 * fixed FT (IEEE 802.11r) authentication after a failed association to
83 * added support for configuring Phase 2 (inner/tunneled) authentication
84 method with wpa_gui-qt4
87 * added support for EAP Sequences in EAP-FAST Phase 2
88 * added support for using TNC with EAP-FAST
89 * added driver_ps3 for the PS3 Linux wireless driver
90 * added support for optional cryptobinding with PEAPv0
91 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
92 allow fallback to full handshake if server rejects PAC-Opaque
93 * added fragmentation support for EAP-TNC
94 * added support for parsing PKCS #8 formatted private keys into the
95 internal TLS implementation (both PKCS #1 RSA key and PKCS #8
96 encapsulated RSA key can now be used)
97 * added option of using faster, but larger, routines in the internal
98 LibTomMath (for internal TLS implementation) to speed up DH and RSA
99 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
100 * fixed race condition between disassociation event and group key
101 handshake to avoid getting stuck in incorrect state [Bug 261]
102 * fixed opportunistic key caching (proactive_key_caching)
105 * removed 'nai' and 'eappsk' network configuration variables that were
106 previously used for configuring user identity and key for EAP-PSK,
107 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
108 replacement for 'nai' (if old configuration used a separate
109 'identity' value, that would now be configured as
110 'anonymous_identity'). 'password' field is now used as the
111 replacement for 'eappsk' (it can also be set using hexstring to
112 present random binary data)
113 * removed '-w' command line parameter (wait for interface to be added,
114 if needed); cleaner way of handling this functionality is to use an
115 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
116 when an interface is added
117 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
118 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
119 indicating when new scan results become available
120 * added new ctrl_iface command, BSS, to allow scan results to be
121 fetched without hitting the message size limits (this command
122 can be used to iterate through the scan results one BSS at the time)
123 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
124 attributes in EAP-SIM Start/Response when using fast reauthentication
125 * fixed EAPOL not to end up in infinite loop when processing dynamic
126 WEP keys with IEEE 802.1X
127 * fixed problems in getting NDIS events from WMI on Windows 2000
130 * added support for Makefile builds to include debug-log-to-a-file
131 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
132 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
133 lengths properly to avoid potential crash caused by invalid messages
134 * added data structure for storing allocated buffers (struct wpabuf);
135 this does not affect wpa_supplicant usage, but many of the APIs
136 changed and various interfaces (e.g., EAP) is not compatible with old
138 * added support for protecting EAP-AKA/Identity messages with
139 AT_CHECKCODE (optional feature in RFC 4187)
140 * added support for protected result indication with AT_RESULT_IND for
141 EAP-SIM and EAP-AKA (phase1="result_ind=1")
142 * added driver_wext workaround for race condition between scanning and
143 association with drivers that take very long time to scan all
144 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
145 using a longer hardcoded timeout for the scan if the driver supports
146 notifications for scan completion (SIOCGIWSCAN event); this helps,
147 e.g., in cases where wpa_supplicant and madwifi driver ended up in
148 loop where the driver did not even try to associate
149 * stop EAPOL timer tick when no timers are in use in order to reduce
150 power consumption (no need to wake up the process once per second)
152 * added support for privilege separation (run only minimal part of
153 wpa_supplicant functionality as root and rest as unprivileged,
154 non-root process); see 'Privilege separation' in README for details;
155 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
157 * changed scan results data structure to include all information
158 elements to make it easier to support new IEs; old get_scan_result()
159 driver_ops is still supported for backwards compatibility (results
160 are converted internally to the new format), but all drivers should
161 start using the new get_scan_results2() to make them more likely to
162 work with new features
163 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
164 application, i.e., it does not require Qt3Support anymore; Windows
165 binary of wpa_gui.exe is now from this directory and only requires
166 QtCore4.dll and QtGui4.dll libraries
167 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
168 available as a separate package to make wpa_gui installation easier:
169 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
170 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
171 only shared key/password authentication is supported in this version
174 * added support for configuring password as NtPasswordHash
175 (16-byte MD4 hash of password) in hash:<32 hex digits> format
176 * added support for fallback from abbreviated TLS handshake to
177 full handshake when using EAP-FAST (e.g., due to an expired
179 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
180 draft (draft-ietf-emu-eap-gpsk-07.txt)
181 * added support for drivers that take care of RSN 4-way handshake
182 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
183 WPA_ALG_PMK in set_key)
184 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
185 .config); this version supports only ap_scan=2 mode and allow the
186 driver to take care of the 4-way handshake
187 * fixed a buffer overflow in parsing TSF from scan results when using
188 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
190 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
191 * fixed an integer overflow issue in the ASN.1 parser used by the
192 (experimental) internal TLS implementation to avoid a potential
194 * fixed a race condition with -W option (wait for a control interface
195 monitor before starting) that could have caused the first messages to
197 * added support for processing TNCC-TNCS-Messages to report
198 recommendation (allow/none/isolate) when using TNC [Bug 243]
201 * added network configuration parameter 'frequency' for setting
202 initial channel for IBSS (adhoc) networks
203 * added experimental IEEE 802.11r/D6.0 support
204 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
205 * updated EAP-PSK to use the IANA-allocated EAP type 47
206 * fixed EAP-PAX key derivation
207 * fixed EAP-PSK bit ordering of the Flags field
208 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
209 tunnelled identity request (previously, the identifier from the outer
210 method was used, not the tunnelled identifier which could be
212 * added support for fragmentation of outer TLS packets during Phase 2
213 of EAP-PEAP/TTLS/FAST
214 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
215 * added support for EAP-FAST authentication with inner methods that
216 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
217 for PAC provisioning)
218 * added support for authenticated EAP-FAST provisioning
219 * added support for configuring maximum number of EAP-FAST PACs to
220 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
221 * added support for storing EAP-FAST PACs in binary format
222 (fast_pac_format=binary in phase1 string)
223 * fixed dbus ctrl_iface to validate message interface before
224 dispatching to avoid a possible segfault [Bug 190]
225 * fixed PeerKey key derivation to use the correct PRF label
226 * updated Windows binary build to link against OpenSSL 0.9.8d and
227 added support for EAP-FAST
228 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
229 draft (draft-ietf-emu-eap-gpsk-04.txt)
230 * fixed EAP-AKA Notification processing to allow Notification to be
231 processed after AKA Challenge response has been sent
232 * updated to use IEEE 802.11w/D2.0 for management frame protection
234 * fixed EAP-TTLS implementation not to crash on use of freed memory
235 if TLS library initialization fails
236 * added support for EAP-TNC (Trusted Network Connect)
237 (this version implements the EAP-TNC method and EAP-TTLS changes
238 needed to run two methods in sequence (IF-T) and the IF-IMC and
239 IF-TNCCS interfaces from TNCC)
242 * added experimental, integrated TLSv1 client implementation with the
243 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
244 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
245 .config); this can be useful, e.g., if the target system does not
246 have a suitable TLS library and a minimal code size is required
247 (total size of this internal TLS/crypto code is bit under 50 kB on
248 x86 and the crypto code is shared by rest of the supplicant so some
249 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
250 * removed STAKey handshake since PeerKey handshake has replaced it in
251 IEEE 802.11ma and there are no known deployments of STAKey
252 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
253 draft (draft-ietf-emu-eap-gpsk-01.txt)
254 * added preliminary implementation of IEEE 802.11w/D1.0 (management
256 (Note: this requires driver support to work properly.)
257 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
258 * fixed Windows named pipes ctrl_iface to not stop listening for
259 commands if client program opens a named pipe and closes it
260 immediately without sending a command
261 * fixed USIM PIN status determination for the case that PIN is not
262 needed (this allows EAP-AKA to be used with USIM cards that do not
264 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
265 be used with cards that do not support file selection based on
267 * added support for matching the subjectAltName of the authentication
268 server certificate against multiple name components (e.g.,
269 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
270 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
271 affects IEEE 802.1X with dynamic WEP keys)
272 * changed ctrl_iface network configuration 'get' operations to not
273 return password/key material; if these fields are requested, "*"
274 will be returned if the password/key is set, but the value of the
275 parameter is not exposed
278 * added support for building Windows version with UNICODE defined
279 (wide-char functions)
280 * driver_ndis: fixed static WEP configuration to avoid race condition
281 issues with some NDIS drivers between association and setting WEP
283 * driver_ndis: added validation for IELength value in scan results to
284 avoid crashes when using buggy NDIS drivers [Bug 165]
285 * fixed Release|Win32 target in the Visual Studio project files
286 (previously, only Debug|Win32 target was set properly)
287 * changed control interface API call wpa_ctrl_pending() to allow it to
288 return -1 on error (e.g., connection lost); control interface clients
289 will need to make sure that they verify that the value is indeed >0
290 when determining whether there are pending messages
291 * added an alternative control interface backend for Windows targets:
292 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
293 control interface mechanism for Windows builds (previously, UDP to
295 * changed ctrl_interface configuration for UNIX domain sockets:
296 - deprecated ctrl_interface_group variable (it may be removed in
298 - allow both directory and group be configured with ctrl_interface
299 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
300 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
301 case when group is not changed
302 * added support for controlling more than one interface per process in
304 * added a workaround for a case where the AP is using unknown address
305 (e.g., MAC address of the wired interface) as the source address for
306 EAPOL-Key frames; previously, that source address was used as the
307 destination for EAPOL-Key frames and in key derivation; now, BSSID is
308 used even if the source address does not match with it
309 (this resolves an interoperability issue with Thomson SpeedTouch 580)
310 * added a workaround for UDP-based control interface (which was used in
311 Windows builds before this release) to prevent packets with forged
312 addresses from being accepted as local control requests
313 * removed ndis_events.cpp and possibility of using external
314 ndis_events.exe; C version (ndis_events.c) is fully functional and
315 there is no desire to maintain two separate versions of this
317 * ndis_events: Changed NDIS event notification design to use WMI to
318 learn the adapter description through Win32_PnPEntity class; this
319 should fix some cases where the adapter name was not recognized
320 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
322 * fixed selection of the first network in ap_scan=2 mode; previously,
323 wpa_supplicant could get stuck in SCANNING state when only the first
324 network for enabled (e.g., after 'wpa_cli select_network 0')
325 * winsvc: added support for configuring ctrl_interface parameters in
326 registry (ctrl_interface string value in
327 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
328 required to enable control interface (previously, this was hardcoded
330 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
331 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
334 * fixed build with CONFIG_STAKEY=y [Bug 143]
335 * added support for doing MLME (IEEE 802.11 management frame
336 processing) in wpa_supplicant when using Devicescape IEEE 802.11
337 stack (wireless-dev.git tree)
338 * added a new network block configuration option, fragment_size, to
339 configure the maximum EAP fragment size
340 * driver_ndis: Disable WZC automatically for the selected interface to
341 avoid conflicts with two programs trying to control the radio; WZC
342 will be re-enabled (if it was enabled originally) when wpa_supplicant
344 * added an experimental TLSv1 client implementation
345 (CONFIG_TLS=internal) that can be used instead of an external TLS
346 library, e.g., to reduce total size requirement on systems that do
347 not include any TLS library by default (this is not yet complete;
348 basic functionality is there, but certificate validation is not yet
350 * added PeerKey handshake implementation for IEEE 802.11e
351 direct link setup (DLS) to replace STAKey handshake
352 * fixed WPA PSK update through ctrl_iface for the case where the old
353 PSK was derived from an ASCII passphrase and the new PSK is set as
354 a raw PSK (hex string)
355 * added new configuration option for identifying which network block
356 was used (id_str in wpa_supplicant.conf; included on
357 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
358 variable in wpa_cli action scripts; in addition WPA_ID variable is
359 set to the current unique identifier that wpa_supplicant assigned
360 automatically for the network and that can be used with
361 GET_NETWORK/SET_NETWORK ctrl_iface commands)
362 * wpa_cli action script is now called only when the connect/disconnect
363 status changes or when associating with a different network
364 * fixed configuration parser not to remove CCMP from group cipher list
365 if WPA-None (adhoc) is used (pairwise=NONE in that case)
366 * fixed integrated NDIS events processing not to hang the process due
367 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
368 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
369 draft-clancy-emu-eap-shared-secret-00.txt)
370 * added Microsoft Visual Studio 2005 solution and project files for
371 build wpa_supplicant for Windows (see vs2005 subdirectory)
372 * eloop_win: fixed unregistration of Windows events
373 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
374 at the end of RSN pre-authentication and added unregistration of
375 a Windows event to avoid getting eloop_win stuck with an invalid
377 * driver_ndis: added support for selecting AP based on BSSID
378 * added new environmental variable for wpa_cli action scripts:
379 WPA_CTRL_DIR is the current control interface directory
380 * driver_ndis: added support for using NDISUIO instead of WinPcap for
381 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
382 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
383 wpa_supplicant without requiring WinPcap; note that using NDISUIO
384 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
385 only one application to open the device
386 * changed NDIS driver naming to only include device GUID, e.g.,
387 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
388 specific \Device\NPF_ prefix before the GUID; the prefix is still
389 allowed for backwards compatibility, but it is not required anymore
390 when specifying the interface
391 * driver_ndis: re-initialize driver interface is the adapter is removed
392 and re-inserted [Bug 159]
393 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
394 big endian hosts [Bug 146]
397 * fixed EAP-GTC response to include correct user identity when run as
398 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
399 * driver_ndis: Fixed encryption mode configuration for unencrypted
400 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
401 refused to associate with open networks) [Bug 106]
402 * driver_ndis: use BSSID OID polling to detect when IBSS network is
403 formed even when ndis_events code is included since some NDIS drivers
404 do not generate media connect events in IBSS mode
405 * config_winreg: allow global ctrl_interface parameter to be configured
407 * config_winreg: added support for saving configuration data into
409 * added support for controlling network device operational state
410 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
411 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
412 that can use this information)
413 * driver_wext: added support for WE-21 change to SSID configuration
414 * driver_wext: fixed privacy configuration for static WEP keys mode
416 * added an optional driver_ops callback for MLME-SETPROTECTION.request
418 * added support for EAP-SAKE (no EAP method number allocated yet, so
419 this is using the same experimental type 255 as EAP-PSK)
420 * added support for dynamically loading EAP methods (.so files) instead
421 of requiring them to be statically linked in; this is disabled by
422 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
426 * do not try to use USIM APDUs when initializing PC/SC for SIM card
427 access for a network that has not enabled EAP-AKA
428 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
429 v0.5.1 due to the new support for expanded EAP types)
430 * added support for generating EAP Expanded Nak
431 * try to fetch scan results once before requesting new scan when
432 starting up in ap_scan=1 mode (this can speed up initial association
433 a lot with, e.g., madwifi-ng driver)
434 * added support for receiving EAPOL frames from a Linux bridge
435 interface (-bbr0 on command line)
436 * fixed EAPOL re-authentication for sessions that used PMKSA caching
437 * changed EAP method registration to use a dynamic list of methods
438 instead of a static list generated at build time
439 * fixed PMKSA cache deinitialization not to use freed memory when
440 removing PMKSA entries
441 * fixed a memory leak in EAP-TTLS re-authentication
442 * reject WPA/WPA2 message 3/4 if it does not include any valid
444 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
445 if the driver does not support SIOCSIWAUTH
448 * driver_test: added better support for multiple APs and STAs by using
449 a directory with sockets that include MAC address for each device in
450 the name (driver_param=test_dir=/tmp/test)
451 * added support for EAP expanded type (vendor specific EAP methods)
452 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
453 option can be changed if needed
454 * wpa_cli/wpa_gui: skip non-socket files in control directory when
455 using UNIX domain sockets; this avoids selecting an incorrect
456 interface (e.g., a PID file could be in this directory, even though
457 use of this directory for something else than socket files is not
459 * fixed TLS library deinitialization after RSN pre-authentication not
460 to disable TLS library for normal authentication
461 * driver_wext: Remove null-termination from SSID length if the driver
462 used it; some Linux drivers do this and they were causing problems in
463 wpa_supplicant not finding matching configuration block. This change
464 would break a case where the SSID actually ends in '\0', but that is
465 not likely to happen in real use.
466 * fixed PMKSA cache processing not to trigger deauthentication if the
467 current PMKSA cache entry is replaced with a valid new entry
468 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
469 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
472 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
473 * added experimental STAKey handshake implementation for IEEE 802.11e
474 direct link setup (DLS); note: this is disabled by default in both
475 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
477 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
478 decrypt AT_ENCR_DATA attributes correctly
479 * fixed EAP-AKA to allow resynchronization within the same session
480 * made code closer to ANSI C89 standard to make it easier to port to
481 other C libraries and compilers
482 * started moving operating system or C library specific functions into
483 wrapper functions defined in os.h and implemented in os_*.c to make
485 * wpa_supplicant can now be built with Microsoft Visual C++
486 (e.g., with the freely available Toolkit 2003 version or Visual
487 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
488 example makefile for nmake
489 * added support for using Windows registry for command line parameters
490 (CONFIG_MAIN=main_winsvc) and configuration data
491 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
492 contents; this version can be run both as a Windows service and as a
493 normal application; 'wpasvc.exe app' to start as applicant,
494 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
495 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
497 * made it possible to link ndis_events.exe functionality into
498 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
499 * added better support for multiple control interface backends
500 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
501 * fixed PC/SC code to use correct length for GSM AUTH command buffer
502 and to not use pioRecvPci with SCardTransmit() calls; these were not
503 causing visible problems with pcsc-lite, but Windows Winscard.dll
504 refused the previously used parameters; this fixes EAP-SIM and
505 EAP-AKA authentication using SIM/USIM card under Windows
506 * added new event loop implementation for Windows using
507 WaitForMultipleObject() instead of select() in order to allow waiting
508 for non-socket objects; this can be selected with
509 CONFIG_ELOOP=eloop_win in .config
510 * added support for selecting l2_packet implementation in .config
511 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
512 winpcap, freebsd, none)
513 * added new l2_packet implementation for WinPcap
514 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
515 reduce latency in EAPOL receive processing from about 100 ms to about
517 * added support for EAP-FAST key derivation using other ciphers than
518 RC4-128-SHA for authentication and AES128-SHA for provisioning
519 * added support for configuring CA certificate as DER file and as a
521 * fixed private key configuration as configuration blob and added
522 support for using PKCS#12 as a blob
523 * tls_gnutls: added support for using PKCS#12 files; added support for
525 * added support for loading trusted CA certificates from Windows
526 certificate store: ca_cert="cert_store://<name>", where <name> is
527 likely CA (Intermediate CA certificates) or ROOT (root certificates)
528 * added C version of ndis_events.cpp and made it possible to build this
529 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
530 easily on cross-compilation builds
531 * added wpasvc.exe into Windows binary release; this is an alternative
532 version of wpa_supplicant.exe with configuration backend using
533 Windows registry and with the entry point designed to run as a
535 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
536 wpasvc.exe and removed this additional tool from the Windows binary
537 release since it is not needed anymore
538 * load winscard.dll functions dynamically when building with MinGW
539 since MinGW does not yet include winscard library
541 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
542 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
543 and WinPcap to receive frames sent to PAE group address
544 * disable EAP state machine when IEEE 802.1X authentication is not used
545 in order to get rid of bogus "EAP failed" messages
546 * fixed OpenSSL error reporting to go through all pending errors to
547 avoid confusing reports of old errors being reported at later point
549 * fixed configuration file updating to not write empty variables
550 (e.g., proto or key_mgmt) that the file parser would not accept
551 * fixed ADD_NETWORK ctrl_iface command to use the same default values
552 for variables as empty network definitions read from config file
554 * fixed EAP state machine to not discard EAP-Failure messages in many
555 cases (e.g., during TLS handshake)
556 * fixed a infinite loop in private key reading if the configured file
557 cannot be parsed successfully
558 * driver_madwifi: added support for madwifi-ng
559 * wpa_gui: do not display password/PSK field contents
560 * wpa_gui: added CA certificate configuration
561 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
562 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
563 the new AP is using different WPA/RSN IE
564 * use longer timeout for IEEE 802.11 association to avoid problems with
565 drivers that may take more than five second to associate
568 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
569 RSN IE, but WPA IE would match with wpa_supplicant configuration
570 * added support for named configuration blobs in order to avoid having
571 to use file system for external files (e.g., certificates);
572 variables can be set to "blob://<blob name>" instead of file path to
573 use a named blob; supported fields: pac_file, client_cert,
575 * fixed RSN pre-authentication (it was broken in the clean up of WPA
576 state machine interface in v0.4.5)
577 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
578 sure the driver configures broadcast decryption correctly
579 * added ca_path (and ca_path2) configuration variables that can be used
580 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
581 system-wide trusted CA list
582 * added support for starting wpa_supplicant without a configuration
583 file (-C argument must be used to set ctrl_interface parameter for
584 this case; in addition, -p argument can be used to provide
585 driver_param; these new arguments can also be used with a
586 configuration to override the values from the configuration)
587 * added global control interface that can be optionally used for adding
588 and removing network interfaces dynamically (-g command line argument
589 for both wpa_supplicant and wpa_cli) without having to restart
590 wpa_supplicant process
592 - try to save configuration whenever something is modified
593 - added WEP key configuration
594 - added possibility to edit the current network configuration
595 * driver_ndis: fixed driver polling not to increase frequency on each
596 received EAPOL frame due to incorrectly cancelled timeout
597 * added simple configuration file examples (in examples subdirectory)
598 * fixed driver_wext.c to filter wireless events based on ifindex to
599 avoid interfaces receiving events from other interfaces
600 * delay sending initial EAPOL-Start couple of seconds to speed up
601 authentication for the most common case of Authenticator starting
602 EAP authentication immediately after association
605 * added a workaround for clearing keys with ndiswrapper to allow
606 roaming from WPA enabled AP to plaintext one
607 * added docbook documentation (doc/docbook) that can be used to
608 generate, e.g., man pages
609 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
610 PF_PACKET in order to prepare for network devices that do not use
611 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
612 * use receipt of EAPOL-Key frame as a lower layer success indication
613 for EAP state machine to allow recovery from dropped EAP-Success
615 * cleaned up internal EAPOL frame processing by not including link
616 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
617 header is added only when transmitted the frame; this makes it easier
618 to use wpa_supplicant on link layers that use different header than
620 * updated EAP-PSK to use draft 9 by default since this can now be
621 tested with hostapd; removed support for draft 3, including
622 server_nai configuration option from network blocks
623 * driver_wired: add PAE address to the multicast address list in order
624 to be able to receive EAPOL frames with drivers that do not include
625 these multicast addresses by default
626 * driver_wext: add support for WE-19
627 * added support for multiple configuration backends (CONFIG_BACKEND
628 option); currently, only 'file' is supported (i.e., the format used
629 in wpa_supplicant.conf)
630 * added support for updating configuration ('wpa_cli save_config');
631 this is disabled by default and can be enabled with global
632 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
633 and wpa_gui to store the configuration changes in a permanent store
634 * added GET_NETWORK ctrl_iface command
635 (e.g., 'wpa_cli get_network 0 ssid')
638 * replaced OpenSSL patch for EAP-FAST support
639 (openssl-tls-extensions.patch) with a more generic and correct
640 patch (the new patch is not compatible with the previous one, so the
641 OpenSSL library will need to be patched with the new patch in order
642 to be able to build wpa_supplicant with EAP-FAST support)
643 * added support for using Windows certificate store (through CryptoAPI)
644 for client certificate and private key operations (EAP-TLS)
645 (see wpa_supplicant.conf for more information on how to configure
646 this with private_key)
647 * ported wpa_gui to Windows
648 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
649 built with the open source version of the Qt4 for Windows
650 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
651 with drivers that do not support WPA
652 * ndis_events: fixed Windows 2000 support
653 * added support for enabling/disabling networks from the list of all
654 configured networks ('wpa_cli enable_network <network id>' and
655 'wpa_cli disable_network <network id>')
656 * added support for adding and removing network from the current
657 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
658 <network id>'); added networks are disabled by default and they can
659 be enabled with enable_network command once the configuration is done
660 for the new network; note: configuration file is not yet updated, so
661 these new networks are lost when wpa_supplicant is restarted
662 * added support for setting network configuration parameters through
663 the control interface, for example:
664 wpa_cli set_network 0 ssid "\"my network\""
665 * fixed parsing of strings that include both " and # within double
666 quoted area (e.g., "start"#end")
667 * added EAP workaround for PEAP session resumption: allow outer,
668 i.e., not tunneled, EAP-Success to terminate session since; this can
669 be disabled with eap_workaround=0
670 (this was allowed for PEAPv1 before, but now it is also allowed for
671 PEAPv0 since at least one RADIUS authentication server seems to be
672 doing this for PEAPv0, too)
673 * wpa_gui: added preliminary support for adding new networks to the
674 wpa_supplicant configuration (double click on the scan results to
675 open network configuration)
678 * removed interface for external EAPOL/EAP supplicant (e.g.,
679 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
680 anymore and is unlikely to be used by anyone
681 * driver_ndis: fixed WinPcap 3.0 support
682 * fixed build with CONFIG_DNET_PCAP=y on Linux
683 * l2_packet: moved different implementations into separate files
687 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
688 (note: ipw2100-1.1.0 is likely to require an update to work with
690 * added support for using ap_scan=2 mode with multiple network blocks;
691 wpa_supplicant will go through the networks one by one until the
692 driver reports a successful association; this uses the same order for
693 networks as scan_ssid=1 scans, i.e., the priority field is ignored
694 and the network block order in the file is used instead
695 * fixed a potential issue in RSN pre-authentication ending up using
696 freed memory if pre-authentication times out
697 * added support for matching alternative subject name extensions of the
698 authentication server certificate; new configuration variables
699 altsubject_match and altsubject_match2
700 * driver_ndis: added support for IEEE 802.1X authentication with wired
702 * added support for querying private key password (EAP-TLS) through the
703 control interface (wpa_cli/wpa_gui) if one is not included in the
705 * driver_broadcom: fixed couple of memory leaks in scan result
707 * EAP-PAX is now registered as EAP type 46
708 * fixed EAP-PAX MAC calculation
709 * fixed EAP-PAX CK and ICK key derivation
710 * added support for using password with EAP-PAX (as an alternative to
711 entering key with eappsk); SHA-1 hash of the password will be used as
713 * added support for arbitrary driver interface parameters through the
714 configuration file with a new driver_param field; this adds a new
715 driver_ops function set_param()
716 * added possibility to override l2_packet module with driver interface
717 API (new send_eapol handler); this can be used to implement driver
718 specific TX/RX functions for EAPOL frames
719 * fixed ctrl_interface_group processing for the case where gid is
720 entered as a number, not group name
721 * driver_test: added support for testing hostapd with wpa_supplicant
722 by using test driver interface without any kernel drivers or network
726 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
727 packets to be encrypted; this was apparently broken by the changed
728 ioctl order in v0.4.0
729 * driver_madwifi: added preliminary support for compiling against 'BSD'
730 branch of madwifi CVS tree
731 * added support for EAP-MSCHAPv2 password retries within the same EAP
732 authentication session
733 * added support for password changes with EAP-MSCHAPv2 (used when the
734 password has expired)
735 * added support for reading additional certificates from PKCS#12 files
736 and adding them to the certificate chain
737 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
739 * fixed a possible double free in EAP-TTLS fast-reauthentication when
740 identity or password is entered through control interface
741 * display EAP Notification messages to user through control interface
742 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
743 * added GUI version of wpa_cli, wpa_gui; this is not build
744 automatically with 'make'; use 'make wpa_gui' to build (this requires
745 Qt development tools)
746 * added 'disconnect' command to control interface for setting
747 wpa_supplicant in state where it will not associate before
748 'reassociate' command has been used
749 * added support for selecting a network from the list of all configured
750 networks ('wpa_cli select_network <network id>'; this disabled all
751 other networks; to re-enable, 'wpa_cli select_network any')
752 * added support for getting scan results through control interface
753 * added EAP workaround for PEAPv1 session resumption: allow outer,
754 i.e., not tunneled, EAP-Success to terminate session since; this can
755 be disabled with eap_workaround=0
757 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
758 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
759 used to reduce the size of the wpa_supplicant considerably if
760 debugging code is not needed
761 * fixed EAPOL-Key validation to drop packets with invalid Key Data
762 Length; such frames could have crashed wpa_supplicant due to buffer
764 * added support for wired authentication (IEEE 802.1X on wired
765 Ethernet); driver interface 'wired'
766 * obsoleted set_wpa() handler in the driver interface API (it can be
767 replaced by moving enable/disable functionality into init()/deinit())
768 (calls to set_wpa() are still present for backwards compatibility,
769 but they may be removed in the future)
770 * driver_madwifi: fixed association in plaintext mode
771 * modified the EAP workaround that accepts EAP-Success with incorrect
772 Identifier to be even less strict about verification in order to
773 interoperate with some authentication servers
774 * added support for sending TLS alerts
775 * added support for 'any' SSID wildcard; if ssid is not configured or
776 is set to an empty string, any SSID will be accepted for non-WPA AP
777 * added support for asking PIN (for SIM) from frontends (e.g.,
778 wpa_cli); if a PIN is needed, but not included in the configuration
779 file, a control interface request is sent and EAP processing is
780 delayed until the PIN is available
781 * added support for using external devices (e.g., a smartcard) for
782 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
783 new wpa_supplicant.conf variables:
784 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
785 - network: engine, engine_id, key_id
786 * added experimental support for EAP-PAX
787 * added monitor mode for wpa_cli (-a<path to a program to run>) that
788 allows external commands (e.g., shell scripts) to be run based on
789 wpa_supplicant events, e.g., when authentication has been completed
790 and data connection is ready; other related wpa_cli arguments:
791 -B (run in background), -P (write PID file); wpa_supplicant has a new
792 command line argument (-W) that can be used to make it wait until a
793 control interface command is received in order to avoid missing
795 * added support for opportunistic WPA2 PMKSA key caching (disabled by
796 default, can be enabled with proactive_key_caching=1)
797 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
798 Authenticator rejects PMKSA caching attempt and the driver is not
799 using assoc_info events
800 * added -P<pid file> argument for wpa_supplicant to write the current
801 process id into a file
803 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
804 * added new phase1 option parameter, include_tls_length=1, to force
805 wpa_supplicant to add TLS Message Length field to all TLS messages
806 even if the packet is not fragmented; this may be needed with some
807 authentication servers
808 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
809 using drivers that take care of AP selection (e.g., when using
811 * fixed reprocessing of pending request after ctrl_iface requests for
812 identity/password/otp
813 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
814 EAP-PEAP and EAP-TTLS
815 * all drivers using driver_wext: set interface up and select Managed
816 mode when starting wpa_supplicant; set interface down when exiting
817 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
818 ipw2100 and ipw2200; please note that this also changed the
819 configuration variable in .config to CONFIG_DRIVER_IPW
822 * fixed a busy loop introduced in v0.3.5 for scan result processing
823 when no matching AP is found
826 * added a workaround for an interoperability issue with a Cisco AP
828 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
829 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
830 retransmission of dropped frames)
831 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
832 (e.g., segfault when processing EAPOL-Key frames)
833 * fixed EAP workaround and fast reauthentication configuration for
834 RSN pre-authentication; previously these were disabled and
835 pre-authentication would fail if the used authentication server
836 requires EAP workarounds
837 * added support for blacklisting APs that fail or timeout
838 authentication in ap_scan=1 mode so that all APs are tried in cases
839 where the ones with strongest signal level are failing authentication
840 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
841 authentication attempt
842 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
843 in the previous authentication (previously, only Phase 1 success was
847 * added preliminary support for IBSS (ad-hoc) mode configuration
848 (mode=1 in network block); this included a new key_mgmt mode
849 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
850 key management; see wpa_supplicant.conf for more details and an
851 example on how to configure this (note: this is currently implemented
852 only for driver_hostapd.c, but the changes should be trivial to add
853 in associate() handler for other drivers, too (assuming the driver
855 * added preliminary port for native Windows (i.e., no cygwin) using
859 * added optional support for GNU Readline and History Libraries for
860 wpa_cli (CONFIG_READLINE)
861 * cleaned up EAP state machine <-> method interface and number of
862 small problems with error case processing not terminating on
863 EAP-Failure but waiting for timeout
864 * added couple of workarounds for interoperability issues with a
865 Cisco AP when using WPA2
866 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
867 Note: This requires a patch for openssl to add support for TLS
868 extensions and number of workarounds for operations without
869 certificates. Proof of concept type of experimental patch is
870 included in openssl-tls-extensions.patch.
873 * fixed private key loading for cases where passphrase is not set
874 * fixed Windows/cygwin L2 packet handler freeing; previous version
875 could cause a segfault when RSN pre-authentication was completed
876 * added support for PMKSA caching with drivers that generate RSN IEs
877 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
878 but similar code can be easily added to driver_ndiswrapper.c once
879 ndiswrapper gets full support for RSN PMKSA caching
880 * improved recovery from PMKID mismatches by requesting full EAP
881 authentication in case of failed PMKSA caching attempt
882 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
883 (this requires that ndis_events is ran while wpa_supplicant is
885 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
886 * added support for driver interfaces to replace the interface name
887 based on driver/OS specific mapping, e.g., in case of driver_ndis,
888 this allows the beginning of the adapter description to be used as
890 * added support for CR+LF (Windows-style) line ends in configuration
892 * driver_ndis: enable radio before starting scanning, disable radio
894 * modified association event handler to set portEnabled = FALSE before
895 clearing port Valid in order to reset EAP state machine and avoid
896 problems with new authentication getting ignored because of state
897 machines ending up in AUTHENTICATED/SUCCESS state based on old
899 * added support for driver events to add PMKID candidates in order to
900 allow drivers to give priority to most likely roaming candidates
901 * driver_hostap: moved PrivacyInvoked configuration to associate()
902 function so that this will not be set for plaintext connections
903 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
904 interface can distinguish plaintext and IEEE 802.1X (no WPA)
906 * fixed static WEP key configuration to use broadcast/default type for
907 all keys (previously, the default TX key was configured as pairwise/
909 * driver_ndis: added legacy WPA capability detection for non-WPA2
911 * added support for setting static WEP keys for IEEE 802.1X without
912 dynamic WEP keying (eapol_flags=0)
915 * added support for reading PKCS#12 (PFX) files (as a replacement for
916 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
917 * fixed compilation with CONFIG_PCSC=y
918 * added new ap_scan mode, ap_scan=2, for drivers that take care of
919 association, but need to be configured with security policy and SSID,
920 e.g., ndiswrapper and NDIS driver; this mode should allow such
921 drivers to work with hidden SSIDs and optimized roaming; when
922 ap_scan=2 is used, only the first network block in the configuration
923 file is used and this configuration should have explicit security
924 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
925 group, proto variables
926 * added experimental port of wpa_supplicant for Windows
927 - driver_ndis.c driver interface (NDIS OIDs)
928 - currently, this requires cygwin and WinPcap
929 - small utility, win_if_list, can be used to get interface name
930 * control interface can now be removed at build time; add
931 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
932 * optional Xsupplicant interface can now be removed at build time;
933 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
934 * added auth_alg to driver interface associate() parameters to make it
935 easier for drivers to configure authentication algorithm as part of
938 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
939 * driver_broadcom: added new driver interface for Broadcom wl.o driver
940 (a generic driver for Broadcom IEEE 802.11a/g cards)
941 * wpa_cli: fixed parsing of -p <path> command line argument
942 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
943 ACK, not tunneled EAP-Success (of which only the first byte was
944 actually send due to a bug in previous code); this seems to
945 interoperate with most RADIUS servers that implements PEAPv1
946 * PEAPv1: added support for terminating PEAP authentication on tunneled
947 EAP-Success message; this can be configured by adding
948 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
949 (some RADIUS servers require this whereas others require a tunneled
951 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
952 the old label for key derivation; previously, the default was 1,
953 but it looks like most existing PEAPv1 implementations use the old
954 label which is thus more suitable default option
955 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
956 * fixed parsing of wep_tx_keyidx
957 * added support for configuring list of allowed Phase 2 EAP types
958 (for both EAP-PEAP and EAP-TTLS) instead of only one type
959 * added support for configuring IEEE 802.11 authentication algorithm
960 (auth_alg; mainly for using Shared Key authentication with static
962 * added support for EAP-AKA (with UMTS SIM)
963 * fixed couple of errors in PCSC handling that could have caused
964 random-looking errors for EAP-SIM
965 * added support for EAP-SIM pseudonyms and fast re-authentication
966 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
968 * added support for EAP-SIM with two challanges
969 (phase1="sim_min_num_chal=3" can be used to require three challenges)
970 * added support for configuring DH/DSA parameters for an ephemeral DH
971 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
972 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
973 and optional DH key exchange to achieve forward secracy with RSA keys
974 * added support for matching subject of the authentication server
975 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
976 configuration variables subject_match and subject_match2
977 * changed SSID configuration in driver_wext.c (used by many driver
978 interfaces) to use ssid_len+1 as the length for SSID since some Linux
980 * fixed couple of unaligned reads in scan result parsing to fix WPA
981 connection on some platforms (e.g., ARM)
982 * added driver interface for Intel ipw2100 driver
983 * added support for LEAP with WPA
984 * added support for larger scan results report (old limit was 4 kB of
985 data, i.e., about 35 or so APs) when using Linux wireless extensions
987 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
988 only if there is a PMKSA cache entry for the current AP
989 * fixed error handling for case where reading of scan results fails:
990 must schedule a new scan or wpa_supplicant will remain waiting
992 * changed debug output to remove shared password/key material by
993 default; all key information can be included with -K command line
994 argument to match the previous behavior
995 * added support for timestamping debug log messages (disabled by
996 default, can be enabled with -t command line argument)
997 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
998 if keys are not configured to be used; this fixes IEEE 802.1X mode
999 with drivers that use this information to configure whether Privacy
1000 bit can be in Beacon frames (e.g., ndiswrapper)
1001 * avoid clearing driver keys if no keys have been configured since last
1002 key clear request; this seems to improve reliability of group key
1003 handshake for ndiswrapper & NDIS driver which seems to be suffering
1004 of some kind of timing issue when the keys are cleared again after
1006 * changed driver interface API:
1007 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
1008 version is being used (now, this is set to 2; previously, it was
1010 - pass pointer to private data structure to all calls
1011 - the new API is not backwards compatible; all in-tree driver
1012 interfaces has been converted to the new API
1013 * added support for controlling multiple interfaces (radios) per
1014 wpa_supplicant process; each interface needs to be listed on the
1015 command line (-c, -i, -D arguments) with -N as a separator
1016 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
1017 * added a workaround for EAP servers that incorrectly use same Id for
1018 sequential EAP packets
1019 * changed libpcap/libdnet configuration to use .config variable,
1020 CONFIG_DNET_PCAP, instead of requiring Makefile modification
1021 * improved downgrade attack detection in IE verification of msg 3/4:
1022 verify both WPA and RSN IEs, if present, not only the selected one;
1023 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
1024 Probe Response frame, and RSN is enabled in wpa_supplicant
1026 * fixed WPA msg 3/4 processing to allow Key Data field contain other
1027 IEs than just one WPA IE
1028 * added support for FreeBSD and driver interface for the BSD net80211
1029 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
1030 required kernel mods have not yet been committed
1031 * made EAP workarounds configurable; enabled by default, can be
1032 disabled with network block option eap_workaround=0
1034 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
1035 * resolved couple of interoperability issues with EAP-PEAPv1 and
1036 Phase 2 (inner EAP) fragment reassembly
1037 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
1038 AP is using non-zero key index for the unicast key and key index zero
1039 for the broadcast key
1040 * driver_hostap: fixed IEEE 802.1X WEP key updates and
1041 re-authentication by allowing unencrypted EAPOL frames when not using
1043 * added a new driver interface, 'wext', which uses only standard,
1044 driver independent functionality in Linux wireless extensions;
1045 currently, this can be used only for non-WPA IEEE 802.1X mode, but
1046 eventually, this is to be extended to support full WPA/WPA2 once
1047 Linux wireless extensions get support for this
1048 * added support for mode in which the driver is responsible for AP
1049 scanning and selection; this is disabled by default and can be
1050 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
1051 this mode can be used, e.g., with generic 'wext' driver interface to
1052 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
1053 supporting wireless extensions.
1054 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
1055 operation with an AP that does not include SSID in the Beacon frames)
1056 * added support for new EAP authentication methods:
1057 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
1058 * added support for asking one-time-passwords from frontends (e.g.,
1059 wpa_cli); this 'otp' command works otherwise like 'password' command,
1060 but the password is used only once and the frontend will be asked for
1061 a new password whenever a request from authenticator requires a
1062 password; this can be used with both EAP-OTP and EAP-GTC
1063 * changed wpa_cli to automatically re-establish connection so that it
1064 does not need to be re-started when wpa_supplicant is terminated and
1066 * improved user data (identity/password/otp) requests through
1067 frontends: process pending EAPOL packets after getting new
1068 information so that full authentication does not need to be
1069 restarted; in addition, send pending requests again whenever a new
1070 frontend is attached
1071 * changed control frontends to use a new directory for socket files to
1072 make it easier for wpa_cli to automatically select between interfaces
1073 and to provide access control for the control interface;
1074 wpa_supplicant.conf: ctrl_interface is now a path
1075 (/var/run/wpa_supplicant is the recommended path) and
1076 ctrl_interface_group can be used to select which group gets access to
1077 the control interface;
1078 wpa_cli: by default, try to connect to the first interface available
1079 in /var/run/wpa_supplicant; this path can be overriden with -p option
1080 and an interface can be selected with -i option (i.e., in most common
1081 cases, wpa_cli does not need to get any arguments)
1082 * added support for LEAP
1083 * added driver interface for Linux ndiswrapper
1084 * added priority option for network blocks in the configuration file;
1085 this allows networks to be grouped based on priority (the scan
1086 results are searched for matches with network blocks in this order)
1089 * sort scan results to improve AP selection
1090 * fixed control interface socket removal for some error cases
1091 * improved scan requesting and authentication timeout
1092 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1094 * PEAP version can now be forced with phase1="peapver=<ver>"
1095 (mostly for testing; by default, the highest version supported by
1096 both the Supplicant and Authentication Server is selected
1098 * added support for madwifi driver (Atheros ar521x)
1099 * added a workaround for cases where AP sets Install Tx/Rx bit for
1100 WPA Group Key messages when pairwise keys are used (without this,
1101 the Group Key would be used for Tx and the AP would drop frames
1103 * added GSM SIM/USIM interface for GSM authentication algorithm for
1104 EAP-SIM; this requires pcsc-lite
1105 * added support for ATMEL AT76C5XXx driver
1106 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1107 does not include key data in the EAPOL-Key frame (i.e., part of
1108 EAP keying material is used as data encryption key)
1109 * added support for using plaintext and static WEP networks
1113 * added support for new EAP authentication methods:
1114 EAP-TTLS/EAP-MD5-Challenge
1116 EAP-TTLS/EAP-MSCHAPv2
1124 EAP-PEAP/MD5-Challenge
1126 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1127 * added support for anonymous identity (to be used when identity is
1128 sent in plaintext; real identity will be used within TLS protected
1129 tunnel (e.g., with EAP-TTLS)
1130 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1131 * added support for requesting identity and password information using
1132 control interface; in other words, the password for EAP-PEAP or
1133 EAP-TTLS does not need to be included in the configuration file since
1134 a frontand (e.g., wpa_cli) can ask it from the user
1135 * improved RSN pre-authentication to use a candidate list and process
1136 all candidates from each scan; not only one per scan
1137 * fixed RSN IE and WPA IE capabilities field parsing
1138 * ignore Tx bit in GTK IE when Pairwise keys are used
1139 * avoid making new scan requests during IEEE 802.1X negotiation
1140 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1141 with TLS support (this replaces the included implementation with
1142 library code to save about 8 kB since the library code is needed
1144 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1145 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1148 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1150 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1151 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1152 - EAP-MD5 (cannot be used with WPA-RADIUS)
1153 [draft-ietf-eap-rfc2284bis-09.txt]
1154 - EAP-TLS [RFC 2716]
1155 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1156 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1157 [draft-kamath-pppext-eap-mschapv2-00.txt]
1158 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1159 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1160 - new configuration file options: eap, identity, password, ca_cert,
1161 client_cert, privatekey, private_key_passwd
1162 - Xsupplicant is not required anymore, but it can be used by
1163 disabling the internal IEEE 802.1X Supplicant with -e command line
1165 - this code is not included in the default build; Makefile need to
1166 be edited for this (uncomment lines for selected functionality)
1167 - EAP-TLS and EAP-PEAP require openssl libraries
1168 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1169 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1170 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1171 EAPOL-Key frames instead of WPA key handshakes)
1172 * added support for IEEE 802.11i/RSN (WPA2)
1173 - improved PTK Key Handshake
1174 - PMKSA caching, pre-authentication
1175 * fixed wpa_supplicant to ignore possible extra data after WPA
1176 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1177 TPTK' error from message 3 of 4-Way Handshake in case the AP
1178 includes extra data after the EAPOL-Key)
1179 * added interface for external programs (frontends) to control
1181 - CLI example (wpa_cli) with interactive mode and command line
1183 - replaced SIGUSR1 status/statistics with the new control interface
1184 * made some feature compile time configurable
1185 - .config file for make
1186 - driver interfaces (hostap, hermes, ..)
1187 - EAPOL/EAP functions
1190 * Initial version of wpa_supplicant
