1 ChangeLog for wpa_supplicant
4 * fixed SHA-256 based key derivation function to match with the
5 standard when using CCMP (for IEEE 802.11r and IEEE 802.11w)
6 (note: this breaks interoperability with previous version) [Bug 307]
7 * changed driver_wext to disconnect at init/deinit to clear state
8 * added explicit disconnect on 4-way handshake failures
9 * added WPS workarounds for known interoperability issues with broken,
10 deployed implementation
11 * update IEEE 802.11w implementation to match with the published
13 * do not send WPS M8 message when learning current AP configuration as
15 * added a workaround for race condition between receive EAPOL frames
16 and association events
17 * fixed compilation with newer GnuTLS versions
18 * fixed PKCS#12 use with OpenSSL 1.0.0
21 * driver_ndis: add PAE group address to the multicast address list to
22 fix wired IEEE 802.1X authentication
23 * fixed IEEE 802.11r key derivation function to match with the standard
24 (note: this breaks interoperability with previous version) [Bug 303]
27 * increased wpa_cli ping interval to 5 seconds and made this
28 configurable with a new command line options (-G<seconds>)
29 * fixed scan buffer processing with WEXT to handle up to 65535
30 byte result buffer (previously, limited to 32768 bytes)
33 * added support for Wi-Fi Protected Setup (WPS)
34 (wpa_supplicant can now be configured to act as a WPS Enrollee to
35 enroll credentials for a network using PIN and PBC methods; in
36 addition, wpa_supplicant can act as a wireless WPS Registrar to
37 configure an AP); WPS support can be enabled by adding CONFIG_WPS=y
38 into .config and setting the runtime configuration variables in
39 wpa_supplicant.conf (see WPS section in the example configuration
40 file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to
41 manage WPS negotiation; see README-WPS for more details
42 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
43 * added support for using driver_test over UDP socket
44 * fixed PEAPv0 Cryptobinding interoperability issue with Windows Server
45 2008 NPS; optional cryptobinding is now enabled (again) by default
46 * fixed PSK editing in wpa_gui
47 * changed EAP-GPSK to use the IANA assigned EAP method type 51
48 * added a Windows installer that includes WinPcap and all the needed
49 DLLs; in addition, it set up the registry automatically so that user
50 will only need start wpa_gui to get prompted to start the wpasvc
51 servide and add a new interface if needed through wpa_gui dialog
52 * updated management frame protection to use IEEE 802.11w/D7.0
55 * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
56 (can be used to simulate test SIM/USIM card with a known private key;
57 enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
58 and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
59 * added a new network configuration option, wpa_ptk_rekey, that can be
60 used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
61 against TKIP deficiencies
62 * added an optional mitigation mechanism for certain attacks against
63 TKIP by delaying Michael MIC error reports by a random amount of time
64 between 0 and 60 seconds; this can be enabled with a build option
65 CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
66 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
68 * updated OpenSSL code for EAP-FAST to use an updated version of the
69 session ticket overriding API that was included into the upstream
70 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
71 needed with that version anymore)
72 * updated userspace MLME instructions to match with the current Linux
73 mac80211 implementation; please also note that this can only be used
74 with driver_nl80211.c (the old code from driver_wext.c was removed)
75 * added support (Linux only) for RoboSwitch chipsets (often found in
76 consumer grade routers); driver interface 'roboswitch'
77 * fixed canceling of PMKSA caching when using drivers that generate
78 RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
82 * added support for SHA-256 as X.509 certificate digest when using the
83 internal X.509/TLSv1 implementation
84 * updated management frame protection to use IEEE 802.11w/D6.0
85 * added support for using SHA256-based stronger key derivation for WPA2
87 * fixed FT (IEEE 802.11r) authentication after a failed association to
89 * added support for configuring Phase 2 (inner/tunneled) authentication
90 method with wpa_gui-qt4
93 * added support for EAP Sequences in EAP-FAST Phase 2
94 * added support for using TNC with EAP-FAST
95 * added driver_ps3 for the PS3 Linux wireless driver
96 * added support for optional cryptobinding with PEAPv0
97 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
98 allow fallback to full handshake if server rejects PAC-Opaque
99 * added fragmentation support for EAP-TNC
100 * added support for parsing PKCS #8 formatted private keys into the
101 internal TLS implementation (both PKCS #1 RSA key and PKCS #8
102 encapsulated RSA key can now be used)
103 * added option of using faster, but larger, routines in the internal
104 LibTomMath (for internal TLS implementation) to speed up DH and RSA
105 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
106 * fixed race condition between disassociation event and group key
107 handshake to avoid getting stuck in incorrect state [Bug 261]
108 * fixed opportunistic key caching (proactive_key_caching)
111 * removed 'nai' and 'eappsk' network configuration variables that were
112 previously used for configuring user identity and key for EAP-PSK,
113 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
114 replacement for 'nai' (if old configuration used a separate
115 'identity' value, that would now be configured as
116 'anonymous_identity'). 'password' field is now used as the
117 replacement for 'eappsk' (it can also be set using hexstring to
118 present random binary data)
119 * removed '-w' command line parameter (wait for interface to be added,
120 if needed); cleaner way of handling this functionality is to use an
121 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
122 when an interface is added
123 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
124 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
125 indicating when new scan results become available
126 * added new ctrl_iface command, BSS, to allow scan results to be
127 fetched without hitting the message size limits (this command
128 can be used to iterate through the scan results one BSS at the time)
129 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
130 attributes in EAP-SIM Start/Response when using fast reauthentication
131 * fixed EAPOL not to end up in infinite loop when processing dynamic
132 WEP keys with IEEE 802.1X
133 * fixed problems in getting NDIS events from WMI on Windows 2000
136 * added support for Makefile builds to include debug-log-to-a-file
137 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
138 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
139 lengths properly to avoid potential crash caused by invalid messages
140 * added data structure for storing allocated buffers (struct wpabuf);
141 this does not affect wpa_supplicant usage, but many of the APIs
142 changed and various interfaces (e.g., EAP) is not compatible with old
144 * added support for protecting EAP-AKA/Identity messages with
145 AT_CHECKCODE (optional feature in RFC 4187)
146 * added support for protected result indication with AT_RESULT_IND for
147 EAP-SIM and EAP-AKA (phase1="result_ind=1")
148 * added driver_wext workaround for race condition between scanning and
149 association with drivers that take very long time to scan all
150 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
151 using a longer hardcoded timeout for the scan if the driver supports
152 notifications for scan completion (SIOCGIWSCAN event); this helps,
153 e.g., in cases where wpa_supplicant and madwifi driver ended up in
154 loop where the driver did not even try to associate
155 * stop EAPOL timer tick when no timers are in use in order to reduce
156 power consumption (no need to wake up the process once per second)
158 * added support for privilege separation (run only minimal part of
159 wpa_supplicant functionality as root and rest as unprivileged,
160 non-root process); see 'Privilege separation' in README for details;
161 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
163 * changed scan results data structure to include all information
164 elements to make it easier to support new IEs; old get_scan_result()
165 driver_ops is still supported for backwards compatibility (results
166 are converted internally to the new format), but all drivers should
167 start using the new get_scan_results2() to make them more likely to
168 work with new features
169 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
170 application, i.e., it does not require Qt3Support anymore; Windows
171 binary of wpa_gui.exe is now from this directory and only requires
172 QtCore4.dll and QtGui4.dll libraries
173 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
174 available as a separate package to make wpa_gui installation easier:
175 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
176 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
177 only shared key/password authentication is supported in this version
180 * added support for configuring password as NtPasswordHash
181 (16-byte MD4 hash of password) in hash:<32 hex digits> format
182 * added support for fallback from abbreviated TLS handshake to
183 full handshake when using EAP-FAST (e.g., due to an expired
185 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
186 draft (draft-ietf-emu-eap-gpsk-07.txt)
187 * added support for drivers that take care of RSN 4-way handshake
188 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
189 WPA_ALG_PMK in set_key)
190 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
191 .config); this version supports only ap_scan=2 mode and allow the
192 driver to take care of the 4-way handshake
193 * fixed a buffer overflow in parsing TSF from scan results when using
194 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
196 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
197 * fixed an integer overflow issue in the ASN.1 parser used by the
198 (experimental) internal TLS implementation to avoid a potential
200 * fixed a race condition with -W option (wait for a control interface
201 monitor before starting) that could have caused the first messages to
203 * added support for processing TNCC-TNCS-Messages to report
204 recommendation (allow/none/isolate) when using TNC [Bug 243]
207 * added network configuration parameter 'frequency' for setting
208 initial channel for IBSS (adhoc) networks
209 * added experimental IEEE 802.11r/D6.0 support
210 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
211 * updated EAP-PSK to use the IANA-allocated EAP type 47
212 * fixed EAP-PAX key derivation
213 * fixed EAP-PSK bit ordering of the Flags field
214 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
215 tunnelled identity request (previously, the identifier from the outer
216 method was used, not the tunnelled identifier which could be
218 * added support for fragmentation of outer TLS packets during Phase 2
219 of EAP-PEAP/TTLS/FAST
220 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
221 * added support for EAP-FAST authentication with inner methods that
222 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
223 for PAC provisioning)
224 * added support for authenticated EAP-FAST provisioning
225 * added support for configuring maximum number of EAP-FAST PACs to
226 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
227 * added support for storing EAP-FAST PACs in binary format
228 (fast_pac_format=binary in phase1 string)
229 * fixed dbus ctrl_iface to validate message interface before
230 dispatching to avoid a possible segfault [Bug 190]
231 * fixed PeerKey key derivation to use the correct PRF label
232 * updated Windows binary build to link against OpenSSL 0.9.8d and
233 added support for EAP-FAST
234 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
235 draft (draft-ietf-emu-eap-gpsk-04.txt)
236 * fixed EAP-AKA Notification processing to allow Notification to be
237 processed after AKA Challenge response has been sent
238 * updated to use IEEE 802.11w/D2.0 for management frame protection
240 * fixed EAP-TTLS implementation not to crash on use of freed memory
241 if TLS library initialization fails
242 * added support for EAP-TNC (Trusted Network Connect)
243 (this version implements the EAP-TNC method and EAP-TTLS changes
244 needed to run two methods in sequence (IF-T) and the IF-IMC and
245 IF-TNCCS interfaces from TNCC)
248 * added experimental, integrated TLSv1 client implementation with the
249 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
250 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
251 .config); this can be useful, e.g., if the target system does not
252 have a suitable TLS library and a minimal code size is required
253 (total size of this internal TLS/crypto code is bit under 50 kB on
254 x86 and the crypto code is shared by rest of the supplicant so some
255 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
256 * removed STAKey handshake since PeerKey handshake has replaced it in
257 IEEE 802.11ma and there are no known deployments of STAKey
258 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
259 draft (draft-ietf-emu-eap-gpsk-01.txt)
260 * added preliminary implementation of IEEE 802.11w/D1.0 (management
262 (Note: this requires driver support to work properly.)
263 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
264 * fixed Windows named pipes ctrl_iface to not stop listening for
265 commands if client program opens a named pipe and closes it
266 immediately without sending a command
267 * fixed USIM PIN status determination for the case that PIN is not
268 needed (this allows EAP-AKA to be used with USIM cards that do not
270 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
271 be used with cards that do not support file selection based on
273 * added support for matching the subjectAltName of the authentication
274 server certificate against multiple name components (e.g.,
275 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
276 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
277 affects IEEE 802.1X with dynamic WEP keys)
278 * changed ctrl_iface network configuration 'get' operations to not
279 return password/key material; if these fields are requested, "*"
280 will be returned if the password/key is set, but the value of the
281 parameter is not exposed
284 * added support for building Windows version with UNICODE defined
285 (wide-char functions)
286 * driver_ndis: fixed static WEP configuration to avoid race condition
287 issues with some NDIS drivers between association and setting WEP
289 * driver_ndis: added validation for IELength value in scan results to
290 avoid crashes when using buggy NDIS drivers [Bug 165]
291 * fixed Release|Win32 target in the Visual Studio project files
292 (previously, only Debug|Win32 target was set properly)
293 * changed control interface API call wpa_ctrl_pending() to allow it to
294 return -1 on error (e.g., connection lost); control interface clients
295 will need to make sure that they verify that the value is indeed >0
296 when determining whether there are pending messages
297 * added an alternative control interface backend for Windows targets:
298 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
299 control interface mechanism for Windows builds (previously, UDP to
301 * changed ctrl_interface configuration for UNIX domain sockets:
302 - deprecated ctrl_interface_group variable (it may be removed in
304 - allow both directory and group be configured with ctrl_interface
305 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
306 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
307 case when group is not changed
308 * added support for controlling more than one interface per process in
310 * added a workaround for a case where the AP is using unknown address
311 (e.g., MAC address of the wired interface) as the source address for
312 EAPOL-Key frames; previously, that source address was used as the
313 destination for EAPOL-Key frames and in key derivation; now, BSSID is
314 used even if the source address does not match with it
315 (this resolves an interoperability issue with Thomson SpeedTouch 580)
316 * added a workaround for UDP-based control interface (which was used in
317 Windows builds before this release) to prevent packets with forged
318 addresses from being accepted as local control requests
319 * removed ndis_events.cpp and possibility of using external
320 ndis_events.exe; C version (ndis_events.c) is fully functional and
321 there is no desire to maintain two separate versions of this
323 * ndis_events: Changed NDIS event notification design to use WMI to
324 learn the adapter description through Win32_PnPEntity class; this
325 should fix some cases where the adapter name was not recognized
326 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
328 * fixed selection of the first network in ap_scan=2 mode; previously,
329 wpa_supplicant could get stuck in SCANNING state when only the first
330 network for enabled (e.g., after 'wpa_cli select_network 0')
331 * winsvc: added support for configuring ctrl_interface parameters in
332 registry (ctrl_interface string value in
333 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
334 required to enable control interface (previously, this was hardcoded
336 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
337 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
340 * fixed build with CONFIG_STAKEY=y [Bug 143]
341 * added support for doing MLME (IEEE 802.11 management frame
342 processing) in wpa_supplicant when using Devicescape IEEE 802.11
343 stack (wireless-dev.git tree)
344 * added a new network block configuration option, fragment_size, to
345 configure the maximum EAP fragment size
346 * driver_ndis: Disable WZC automatically for the selected interface to
347 avoid conflicts with two programs trying to control the radio; WZC
348 will be re-enabled (if it was enabled originally) when wpa_supplicant
350 * added an experimental TLSv1 client implementation
351 (CONFIG_TLS=internal) that can be used instead of an external TLS
352 library, e.g., to reduce total size requirement on systems that do
353 not include any TLS library by default (this is not yet complete;
354 basic functionality is there, but certificate validation is not yet
356 * added PeerKey handshake implementation for IEEE 802.11e
357 direct link setup (DLS) to replace STAKey handshake
358 * fixed WPA PSK update through ctrl_iface for the case where the old
359 PSK was derived from an ASCII passphrase and the new PSK is set as
360 a raw PSK (hex string)
361 * added new configuration option for identifying which network block
362 was used (id_str in wpa_supplicant.conf; included on
363 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
364 variable in wpa_cli action scripts; in addition WPA_ID variable is
365 set to the current unique identifier that wpa_supplicant assigned
366 automatically for the network and that can be used with
367 GET_NETWORK/SET_NETWORK ctrl_iface commands)
368 * wpa_cli action script is now called only when the connect/disconnect
369 status changes or when associating with a different network
370 * fixed configuration parser not to remove CCMP from group cipher list
371 if WPA-None (adhoc) is used (pairwise=NONE in that case)
372 * fixed integrated NDIS events processing not to hang the process due
373 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
374 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
375 draft-clancy-emu-eap-shared-secret-00.txt)
376 * added Microsoft Visual Studio 2005 solution and project files for
377 build wpa_supplicant for Windows (see vs2005 subdirectory)
378 * eloop_win: fixed unregistration of Windows events
379 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
380 at the end of RSN pre-authentication and added unregistration of
381 a Windows event to avoid getting eloop_win stuck with an invalid
383 * driver_ndis: added support for selecting AP based on BSSID
384 * added new environmental variable for wpa_cli action scripts:
385 WPA_CTRL_DIR is the current control interface directory
386 * driver_ndis: added support for using NDISUIO instead of WinPcap for
387 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
388 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
389 wpa_supplicant without requiring WinPcap; note that using NDISUIO
390 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
391 only one application to open the device
392 * changed NDIS driver naming to only include device GUID, e.g.,
393 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
394 specific \Device\NPF_ prefix before the GUID; the prefix is still
395 allowed for backwards compatibility, but it is not required anymore
396 when specifying the interface
397 * driver_ndis: re-initialize driver interface is the adapter is removed
398 and re-inserted [Bug 159]
399 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
400 big endian hosts [Bug 146]
403 * fixed EAP-GTC response to include correct user identity when run as
404 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
405 * driver_ndis: Fixed encryption mode configuration for unencrypted
406 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
407 refused to associate with open networks) [Bug 106]
408 * driver_ndis: use BSSID OID polling to detect when IBSS network is
409 formed even when ndis_events code is included since some NDIS drivers
410 do not generate media connect events in IBSS mode
411 * config_winreg: allow global ctrl_interface parameter to be configured
413 * config_winreg: added support for saving configuration data into
415 * added support for controlling network device operational state
416 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
417 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
418 that can use this information)
419 * driver_wext: added support for WE-21 change to SSID configuration
420 * driver_wext: fixed privacy configuration for static WEP keys mode
422 * added an optional driver_ops callback for MLME-SETPROTECTION.request
424 * added support for EAP-SAKE (no EAP method number allocated yet, so
425 this is using the same experimental type 255 as EAP-PSK)
426 * added support for dynamically loading EAP methods (.so files) instead
427 of requiring them to be statically linked in; this is disabled by
428 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
432 * do not try to use USIM APDUs when initializing PC/SC for SIM card
433 access for a network that has not enabled EAP-AKA
434 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
435 v0.5.1 due to the new support for expanded EAP types)
436 * added support for generating EAP Expanded Nak
437 * try to fetch scan results once before requesting new scan when
438 starting up in ap_scan=1 mode (this can speed up initial association
439 a lot with, e.g., madwifi-ng driver)
440 * added support for receiving EAPOL frames from a Linux bridge
441 interface (-bbr0 on command line)
442 * fixed EAPOL re-authentication for sessions that used PMKSA caching
443 * changed EAP method registration to use a dynamic list of methods
444 instead of a static list generated at build time
445 * fixed PMKSA cache deinitialization not to use freed memory when
446 removing PMKSA entries
447 * fixed a memory leak in EAP-TTLS re-authentication
448 * reject WPA/WPA2 message 3/4 if it does not include any valid
450 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
451 if the driver does not support SIOCSIWAUTH
454 * driver_test: added better support for multiple APs and STAs by using
455 a directory with sockets that include MAC address for each device in
456 the name (driver_param=test_dir=/tmp/test)
457 * added support for EAP expanded type (vendor specific EAP methods)
458 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
459 option can be changed if needed
460 * wpa_cli/wpa_gui: skip non-socket files in control directory when
461 using UNIX domain sockets; this avoids selecting an incorrect
462 interface (e.g., a PID file could be in this directory, even though
463 use of this directory for something else than socket files is not
465 * fixed TLS library deinitialization after RSN pre-authentication not
466 to disable TLS library for normal authentication
467 * driver_wext: Remove null-termination from SSID length if the driver
468 used it; some Linux drivers do this and they were causing problems in
469 wpa_supplicant not finding matching configuration block. This change
470 would break a case where the SSID actually ends in '\0', but that is
471 not likely to happen in real use.
472 * fixed PMKSA cache processing not to trigger deauthentication if the
473 current PMKSA cache entry is replaced with a valid new entry
474 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
475 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
478 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
479 * added experimental STAKey handshake implementation for IEEE 802.11e
480 direct link setup (DLS); note: this is disabled by default in both
481 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
483 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
484 decrypt AT_ENCR_DATA attributes correctly
485 * fixed EAP-AKA to allow resynchronization within the same session
486 * made code closer to ANSI C89 standard to make it easier to port to
487 other C libraries and compilers
488 * started moving operating system or C library specific functions into
489 wrapper functions defined in os.h and implemented in os_*.c to make
491 * wpa_supplicant can now be built with Microsoft Visual C++
492 (e.g., with the freely available Toolkit 2003 version or Visual
493 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
494 example makefile for nmake
495 * added support for using Windows registry for command line parameters
496 (CONFIG_MAIN=main_winsvc) and configuration data
497 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
498 contents; this version can be run both as a Windows service and as a
499 normal application; 'wpasvc.exe app' to start as applicant,
500 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
501 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
503 * made it possible to link ndis_events.exe functionality into
504 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
505 * added better support for multiple control interface backends
506 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
507 * fixed PC/SC code to use correct length for GSM AUTH command buffer
508 and to not use pioRecvPci with SCardTransmit() calls; these were not
509 causing visible problems with pcsc-lite, but Windows Winscard.dll
510 refused the previously used parameters; this fixes EAP-SIM and
511 EAP-AKA authentication using SIM/USIM card under Windows
512 * added new event loop implementation for Windows using
513 WaitForMultipleObject() instead of select() in order to allow waiting
514 for non-socket objects; this can be selected with
515 CONFIG_ELOOP=eloop_win in .config
516 * added support for selecting l2_packet implementation in .config
517 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
518 winpcap, freebsd, none)
519 * added new l2_packet implementation for WinPcap
520 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
521 reduce latency in EAPOL receive processing from about 100 ms to about
523 * added support for EAP-FAST key derivation using other ciphers than
524 RC4-128-SHA for authentication and AES128-SHA for provisioning
525 * added support for configuring CA certificate as DER file and as a
527 * fixed private key configuration as configuration blob and added
528 support for using PKCS#12 as a blob
529 * tls_gnutls: added support for using PKCS#12 files; added support for
531 * added support for loading trusted CA certificates from Windows
532 certificate store: ca_cert="cert_store://<name>", where <name> is
533 likely CA (Intermediate CA certificates) or ROOT (root certificates)
534 * added C version of ndis_events.cpp and made it possible to build this
535 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
536 easily on cross-compilation builds
537 * added wpasvc.exe into Windows binary release; this is an alternative
538 version of wpa_supplicant.exe with configuration backend using
539 Windows registry and with the entry point designed to run as a
541 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
542 wpasvc.exe and removed this additional tool from the Windows binary
543 release since it is not needed anymore
544 * load winscard.dll functions dynamically when building with MinGW
545 since MinGW does not yet include winscard library
547 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
548 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
549 and WinPcap to receive frames sent to PAE group address
550 * disable EAP state machine when IEEE 802.1X authentication is not used
551 in order to get rid of bogus "EAP failed" messages
552 * fixed OpenSSL error reporting to go through all pending errors to
553 avoid confusing reports of old errors being reported at later point
555 * fixed configuration file updating to not write empty variables
556 (e.g., proto or key_mgmt) that the file parser would not accept
557 * fixed ADD_NETWORK ctrl_iface command to use the same default values
558 for variables as empty network definitions read from config file
560 * fixed EAP state machine to not discard EAP-Failure messages in many
561 cases (e.g., during TLS handshake)
562 * fixed a infinite loop in private key reading if the configured file
563 cannot be parsed successfully
564 * driver_madwifi: added support for madwifi-ng
565 * wpa_gui: do not display password/PSK field contents
566 * wpa_gui: added CA certificate configuration
567 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
568 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
569 the new AP is using different WPA/RSN IE
570 * use longer timeout for IEEE 802.11 association to avoid problems with
571 drivers that may take more than five second to associate
574 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
575 RSN IE, but WPA IE would match with wpa_supplicant configuration
576 * added support for named configuration blobs in order to avoid having
577 to use file system for external files (e.g., certificates);
578 variables can be set to "blob://<blob name>" instead of file path to
579 use a named blob; supported fields: pac_file, client_cert,
581 * fixed RSN pre-authentication (it was broken in the clean up of WPA
582 state machine interface in v0.4.5)
583 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
584 sure the driver configures broadcast decryption correctly
585 * added ca_path (and ca_path2) configuration variables that can be used
586 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
587 system-wide trusted CA list
588 * added support for starting wpa_supplicant without a configuration
589 file (-C argument must be used to set ctrl_interface parameter for
590 this case; in addition, -p argument can be used to provide
591 driver_param; these new arguments can also be used with a
592 configuration to override the values from the configuration)
593 * added global control interface that can be optionally used for adding
594 and removing network interfaces dynamically (-g command line argument
595 for both wpa_supplicant and wpa_cli) without having to restart
596 wpa_supplicant process
598 - try to save configuration whenever something is modified
599 - added WEP key configuration
600 - added possibility to edit the current network configuration
601 * driver_ndis: fixed driver polling not to increase frequency on each
602 received EAPOL frame due to incorrectly cancelled timeout
603 * added simple configuration file examples (in examples subdirectory)
604 * fixed driver_wext.c to filter wireless events based on ifindex to
605 avoid interfaces receiving events from other interfaces
606 * delay sending initial EAPOL-Start couple of seconds to speed up
607 authentication for the most common case of Authenticator starting
608 EAP authentication immediately after association
611 * added a workaround for clearing keys with ndiswrapper to allow
612 roaming from WPA enabled AP to plaintext one
613 * added docbook documentation (doc/docbook) that can be used to
614 generate, e.g., man pages
615 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
616 PF_PACKET in order to prepare for network devices that do not use
617 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
618 * use receipt of EAPOL-Key frame as a lower layer success indication
619 for EAP state machine to allow recovery from dropped EAP-Success
621 * cleaned up internal EAPOL frame processing by not including link
622 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
623 header is added only when transmitted the frame; this makes it easier
624 to use wpa_supplicant on link layers that use different header than
626 * updated EAP-PSK to use draft 9 by default since this can now be
627 tested with hostapd; removed support for draft 3, including
628 server_nai configuration option from network blocks
629 * driver_wired: add PAE address to the multicast address list in order
630 to be able to receive EAPOL frames with drivers that do not include
631 these multicast addresses by default
632 * driver_wext: add support for WE-19
633 * added support for multiple configuration backends (CONFIG_BACKEND
634 option); currently, only 'file' is supported (i.e., the format used
635 in wpa_supplicant.conf)
636 * added support for updating configuration ('wpa_cli save_config');
637 this is disabled by default and can be enabled with global
638 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
639 and wpa_gui to store the configuration changes in a permanent store
640 * added GET_NETWORK ctrl_iface command
641 (e.g., 'wpa_cli get_network 0 ssid')
644 * replaced OpenSSL patch for EAP-FAST support
645 (openssl-tls-extensions.patch) with a more generic and correct
646 patch (the new patch is not compatible with the previous one, so the
647 OpenSSL library will need to be patched with the new patch in order
648 to be able to build wpa_supplicant with EAP-FAST support)
649 * added support for using Windows certificate store (through CryptoAPI)
650 for client certificate and private key operations (EAP-TLS)
651 (see wpa_supplicant.conf for more information on how to configure
652 this with private_key)
653 * ported wpa_gui to Windows
654 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
655 built with the open source version of the Qt4 for Windows
656 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
657 with drivers that do not support WPA
658 * ndis_events: fixed Windows 2000 support
659 * added support for enabling/disabling networks from the list of all
660 configured networks ('wpa_cli enable_network <network id>' and
661 'wpa_cli disable_network <network id>')
662 * added support for adding and removing network from the current
663 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
664 <network id>'); added networks are disabled by default and they can
665 be enabled with enable_network command once the configuration is done
666 for the new network; note: configuration file is not yet updated, so
667 these new networks are lost when wpa_supplicant is restarted
668 * added support for setting network configuration parameters through
669 the control interface, for example:
670 wpa_cli set_network 0 ssid "\"my network\""
671 * fixed parsing of strings that include both " and # within double
672 quoted area (e.g., "start"#end")
673 * added EAP workaround for PEAP session resumption: allow outer,
674 i.e., not tunneled, EAP-Success to terminate session since; this can
675 be disabled with eap_workaround=0
676 (this was allowed for PEAPv1 before, but now it is also allowed for
677 PEAPv0 since at least one RADIUS authentication server seems to be
678 doing this for PEAPv0, too)
679 * wpa_gui: added preliminary support for adding new networks to the
680 wpa_supplicant configuration (double click on the scan results to
681 open network configuration)
684 * removed interface for external EAPOL/EAP supplicant (e.g.,
685 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
686 anymore and is unlikely to be used by anyone
687 * driver_ndis: fixed WinPcap 3.0 support
688 * fixed build with CONFIG_DNET_PCAP=y on Linux
689 * l2_packet: moved different implementations into separate files
693 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
694 (note: ipw2100-1.1.0 is likely to require an update to work with
696 * added support for using ap_scan=2 mode with multiple network blocks;
697 wpa_supplicant will go through the networks one by one until the
698 driver reports a successful association; this uses the same order for
699 networks as scan_ssid=1 scans, i.e., the priority field is ignored
700 and the network block order in the file is used instead
701 * fixed a potential issue in RSN pre-authentication ending up using
702 freed memory if pre-authentication times out
703 * added support for matching alternative subject name extensions of the
704 authentication server certificate; new configuration variables
705 altsubject_match and altsubject_match2
706 * driver_ndis: added support for IEEE 802.1X authentication with wired
708 * added support for querying private key password (EAP-TLS) through the
709 control interface (wpa_cli/wpa_gui) if one is not included in the
711 * driver_broadcom: fixed couple of memory leaks in scan result
713 * EAP-PAX is now registered as EAP type 46
714 * fixed EAP-PAX MAC calculation
715 * fixed EAP-PAX CK and ICK key derivation
716 * added support for using password with EAP-PAX (as an alternative to
717 entering key with eappsk); SHA-1 hash of the password will be used as
719 * added support for arbitrary driver interface parameters through the
720 configuration file with a new driver_param field; this adds a new
721 driver_ops function set_param()
722 * added possibility to override l2_packet module with driver interface
723 API (new send_eapol handler); this can be used to implement driver
724 specific TX/RX functions for EAPOL frames
725 * fixed ctrl_interface_group processing for the case where gid is
726 entered as a number, not group name
727 * driver_test: added support for testing hostapd with wpa_supplicant
728 by using test driver interface without any kernel drivers or network
732 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
733 packets to be encrypted; this was apparently broken by the changed
734 ioctl order in v0.4.0
735 * driver_madwifi: added preliminary support for compiling against 'BSD'
736 branch of madwifi CVS tree
737 * added support for EAP-MSCHAPv2 password retries within the same EAP
738 authentication session
739 * added support for password changes with EAP-MSCHAPv2 (used when the
740 password has expired)
741 * added support for reading additional certificates from PKCS#12 files
742 and adding them to the certificate chain
743 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
745 * fixed a possible double free in EAP-TTLS fast-reauthentication when
746 identity or password is entered through control interface
747 * display EAP Notification messages to user through control interface
748 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
749 * added GUI version of wpa_cli, wpa_gui; this is not build
750 automatically with 'make'; use 'make wpa_gui' to build (this requires
751 Qt development tools)
752 * added 'disconnect' command to control interface for setting
753 wpa_supplicant in state where it will not associate before
754 'reassociate' command has been used
755 * added support for selecting a network from the list of all configured
756 networks ('wpa_cli select_network <network id>'; this disabled all
757 other networks; to re-enable, 'wpa_cli select_network any')
758 * added support for getting scan results through control interface
759 * added EAP workaround for PEAPv1 session resumption: allow outer,
760 i.e., not tunneled, EAP-Success to terminate session since; this can
761 be disabled with eap_workaround=0
763 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
764 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
765 used to reduce the size of the wpa_supplicant considerably if
766 debugging code is not needed
767 * fixed EAPOL-Key validation to drop packets with invalid Key Data
768 Length; such frames could have crashed wpa_supplicant due to buffer
770 * added support for wired authentication (IEEE 802.1X on wired
771 Ethernet); driver interface 'wired'
772 * obsoleted set_wpa() handler in the driver interface API (it can be
773 replaced by moving enable/disable functionality into init()/deinit())
774 (calls to set_wpa() are still present for backwards compatibility,
775 but they may be removed in the future)
776 * driver_madwifi: fixed association in plaintext mode
777 * modified the EAP workaround that accepts EAP-Success with incorrect
778 Identifier to be even less strict about verification in order to
779 interoperate with some authentication servers
780 * added support for sending TLS alerts
781 * added support for 'any' SSID wildcard; if ssid is not configured or
782 is set to an empty string, any SSID will be accepted for non-WPA AP
783 * added support for asking PIN (for SIM) from frontends (e.g.,
784 wpa_cli); if a PIN is needed, but not included in the configuration
785 file, a control interface request is sent and EAP processing is
786 delayed until the PIN is available
787 * added support for using external devices (e.g., a smartcard) for
788 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
789 new wpa_supplicant.conf variables:
790 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
791 - network: engine, engine_id, key_id
792 * added experimental support for EAP-PAX
793 * added monitor mode for wpa_cli (-a<path to a program to run>) that
794 allows external commands (e.g., shell scripts) to be run based on
795 wpa_supplicant events, e.g., when authentication has been completed
796 and data connection is ready; other related wpa_cli arguments:
797 -B (run in background), -P (write PID file); wpa_supplicant has a new
798 command line argument (-W) that can be used to make it wait until a
799 control interface command is received in order to avoid missing
801 * added support for opportunistic WPA2 PMKSA key caching (disabled by
802 default, can be enabled with proactive_key_caching=1)
803 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
804 Authenticator rejects PMKSA caching attempt and the driver is not
805 using assoc_info events
806 * added -P<pid file> argument for wpa_supplicant to write the current
807 process id into a file
809 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
810 * added new phase1 option parameter, include_tls_length=1, to force
811 wpa_supplicant to add TLS Message Length field to all TLS messages
812 even if the packet is not fragmented; this may be needed with some
813 authentication servers
814 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
815 using drivers that take care of AP selection (e.g., when using
817 * fixed reprocessing of pending request after ctrl_iface requests for
818 identity/password/otp
819 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
820 EAP-PEAP and EAP-TTLS
821 * all drivers using driver_wext: set interface up and select Managed
822 mode when starting wpa_supplicant; set interface down when exiting
823 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
824 ipw2100 and ipw2200; please note that this also changed the
825 configuration variable in .config to CONFIG_DRIVER_IPW
828 * fixed a busy loop introduced in v0.3.5 for scan result processing
829 when no matching AP is found
832 * added a workaround for an interoperability issue with a Cisco AP
834 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
835 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
836 retransmission of dropped frames)
837 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
838 (e.g., segfault when processing EAPOL-Key frames)
839 * fixed EAP workaround and fast reauthentication configuration for
840 RSN pre-authentication; previously these were disabled and
841 pre-authentication would fail if the used authentication server
842 requires EAP workarounds
843 * added support for blacklisting APs that fail or timeout
844 authentication in ap_scan=1 mode so that all APs are tried in cases
845 where the ones with strongest signal level are failing authentication
846 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
847 authentication attempt
848 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
849 in the previous authentication (previously, only Phase 1 success was
853 * added preliminary support for IBSS (ad-hoc) mode configuration
854 (mode=1 in network block); this included a new key_mgmt mode
855 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
856 key management; see wpa_supplicant.conf for more details and an
857 example on how to configure this (note: this is currently implemented
858 only for driver_hostapd.c, but the changes should be trivial to add
859 in associate() handler for other drivers, too (assuming the driver
861 * added preliminary port for native Windows (i.e., no cygwin) using
865 * added optional support for GNU Readline and History Libraries for
866 wpa_cli (CONFIG_READLINE)
867 * cleaned up EAP state machine <-> method interface and number of
868 small problems with error case processing not terminating on
869 EAP-Failure but waiting for timeout
870 * added couple of workarounds for interoperability issues with a
871 Cisco AP when using WPA2
872 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
873 Note: This requires a patch for openssl to add support for TLS
874 extensions and number of workarounds for operations without
875 certificates. Proof of concept type of experimental patch is
876 included in openssl-tls-extensions.patch.
879 * fixed private key loading for cases where passphrase is not set
880 * fixed Windows/cygwin L2 packet handler freeing; previous version
881 could cause a segfault when RSN pre-authentication was completed
882 * added support for PMKSA caching with drivers that generate RSN IEs
883 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
884 but similar code can be easily added to driver_ndiswrapper.c once
885 ndiswrapper gets full support for RSN PMKSA caching
886 * improved recovery from PMKID mismatches by requesting full EAP
887 authentication in case of failed PMKSA caching attempt
888 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
889 (this requires that ndis_events is ran while wpa_supplicant is
891 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
892 * added support for driver interfaces to replace the interface name
893 based on driver/OS specific mapping, e.g., in case of driver_ndis,
894 this allows the beginning of the adapter description to be used as
896 * added support for CR+LF (Windows-style) line ends in configuration
898 * driver_ndis: enable radio before starting scanning, disable radio
900 * modified association event handler to set portEnabled = FALSE before
901 clearing port Valid in order to reset EAP state machine and avoid
902 problems with new authentication getting ignored because of state
903 machines ending up in AUTHENTICATED/SUCCESS state based on old
905 * added support for driver events to add PMKID candidates in order to
906 allow drivers to give priority to most likely roaming candidates
907 * driver_hostap: moved PrivacyInvoked configuration to associate()
908 function so that this will not be set for plaintext connections
909 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
910 interface can distinguish plaintext and IEEE 802.1X (no WPA)
912 * fixed static WEP key configuration to use broadcast/default type for
913 all keys (previously, the default TX key was configured as pairwise/
915 * driver_ndis: added legacy WPA capability detection for non-WPA2
917 * added support for setting static WEP keys for IEEE 802.1X without
918 dynamic WEP keying (eapol_flags=0)
921 * added support for reading PKCS#12 (PFX) files (as a replacement for
922 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
923 * fixed compilation with CONFIG_PCSC=y
924 * added new ap_scan mode, ap_scan=2, for drivers that take care of
925 association, but need to be configured with security policy and SSID,
926 e.g., ndiswrapper and NDIS driver; this mode should allow such
927 drivers to work with hidden SSIDs and optimized roaming; when
928 ap_scan=2 is used, only the first network block in the configuration
929 file is used and this configuration should have explicit security
930 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
931 group, proto variables
932 * added experimental port of wpa_supplicant for Windows
933 - driver_ndis.c driver interface (NDIS OIDs)
934 - currently, this requires cygwin and WinPcap
935 - small utility, win_if_list, can be used to get interface name
936 * control interface can now be removed at build time; add
937 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
938 * optional Xsupplicant interface can now be removed at build time;
939 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
940 * added auth_alg to driver interface associate() parameters to make it
941 easier for drivers to configure authentication algorithm as part of
944 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
945 * driver_broadcom: added new driver interface for Broadcom wl.o driver
946 (a generic driver for Broadcom IEEE 802.11a/g cards)
947 * wpa_cli: fixed parsing of -p <path> command line argument
948 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
949 ACK, not tunneled EAP-Success (of which only the first byte was
950 actually send due to a bug in previous code); this seems to
951 interoperate with most RADIUS servers that implements PEAPv1
952 * PEAPv1: added support for terminating PEAP authentication on tunneled
953 EAP-Success message; this can be configured by adding
954 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
955 (some RADIUS servers require this whereas others require a tunneled
957 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
958 the old label for key derivation; previously, the default was 1,
959 but it looks like most existing PEAPv1 implementations use the old
960 label which is thus more suitable default option
961 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
962 * fixed parsing of wep_tx_keyidx
963 * added support for configuring list of allowed Phase 2 EAP types
964 (for both EAP-PEAP and EAP-TTLS) instead of only one type
965 * added support for configuring IEEE 802.11 authentication algorithm
966 (auth_alg; mainly for using Shared Key authentication with static
968 * added support for EAP-AKA (with UMTS SIM)
969 * fixed couple of errors in PCSC handling that could have caused
970 random-looking errors for EAP-SIM
971 * added support for EAP-SIM pseudonyms and fast re-authentication
972 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
974 * added support for EAP-SIM with two challanges
975 (phase1="sim_min_num_chal=3" can be used to require three challenges)
976 * added support for configuring DH/DSA parameters for an ephemeral DH
977 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
978 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
979 and optional DH key exchange to achieve forward secracy with RSA keys
980 * added support for matching subject of the authentication server
981 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
982 configuration variables subject_match and subject_match2
983 * changed SSID configuration in driver_wext.c (used by many driver
984 interfaces) to use ssid_len+1 as the length for SSID since some Linux
986 * fixed couple of unaligned reads in scan result parsing to fix WPA
987 connection on some platforms (e.g., ARM)
988 * added driver interface for Intel ipw2100 driver
989 * added support for LEAP with WPA
990 * added support for larger scan results report (old limit was 4 kB of
991 data, i.e., about 35 or so APs) when using Linux wireless extensions
993 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
994 only if there is a PMKSA cache entry for the current AP
995 * fixed error handling for case where reading of scan results fails:
996 must schedule a new scan or wpa_supplicant will remain waiting
998 * changed debug output to remove shared password/key material by
999 default; all key information can be included with -K command line
1000 argument to match the previous behavior
1001 * added support for timestamping debug log messages (disabled by
1002 default, can be enabled with -t command line argument)
1003 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
1004 if keys are not configured to be used; this fixes IEEE 802.1X mode
1005 with drivers that use this information to configure whether Privacy
1006 bit can be in Beacon frames (e.g., ndiswrapper)
1007 * avoid clearing driver keys if no keys have been configured since last
1008 key clear request; this seems to improve reliability of group key
1009 handshake for ndiswrapper & NDIS driver which seems to be suffering
1010 of some kind of timing issue when the keys are cleared again after
1012 * changed driver interface API:
1013 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
1014 version is being used (now, this is set to 2; previously, it was
1016 - pass pointer to private data structure to all calls
1017 - the new API is not backwards compatible; all in-tree driver
1018 interfaces has been converted to the new API
1019 * added support for controlling multiple interfaces (radios) per
1020 wpa_supplicant process; each interface needs to be listed on the
1021 command line (-c, -i, -D arguments) with -N as a separator
1022 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
1023 * added a workaround for EAP servers that incorrectly use same Id for
1024 sequential EAP packets
1025 * changed libpcap/libdnet configuration to use .config variable,
1026 CONFIG_DNET_PCAP, instead of requiring Makefile modification
1027 * improved downgrade attack detection in IE verification of msg 3/4:
1028 verify both WPA and RSN IEs, if present, not only the selected one;
1029 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
1030 Probe Response frame, and RSN is enabled in wpa_supplicant
1032 * fixed WPA msg 3/4 processing to allow Key Data field contain other
1033 IEs than just one WPA IE
1034 * added support for FreeBSD and driver interface for the BSD net80211
1035 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
1036 required kernel mods have not yet been committed
1037 * made EAP workarounds configurable; enabled by default, can be
1038 disabled with network block option eap_workaround=0
1040 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
1041 * resolved couple of interoperability issues with EAP-PEAPv1 and
1042 Phase 2 (inner EAP) fragment reassembly
1043 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
1044 AP is using non-zero key index for the unicast key and key index zero
1045 for the broadcast key
1046 * driver_hostap: fixed IEEE 802.1X WEP key updates and
1047 re-authentication by allowing unencrypted EAPOL frames when not using
1049 * added a new driver interface, 'wext', which uses only standard,
1050 driver independent functionality in Linux wireless extensions;
1051 currently, this can be used only for non-WPA IEEE 802.1X mode, but
1052 eventually, this is to be extended to support full WPA/WPA2 once
1053 Linux wireless extensions get support for this
1054 * added support for mode in which the driver is responsible for AP
1055 scanning and selection; this is disabled by default and can be
1056 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
1057 this mode can be used, e.g., with generic 'wext' driver interface to
1058 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
1059 supporting wireless extensions.
1060 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
1061 operation with an AP that does not include SSID in the Beacon frames)
1062 * added support for new EAP authentication methods:
1063 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
1064 * added support for asking one-time-passwords from frontends (e.g.,
1065 wpa_cli); this 'otp' command works otherwise like 'password' command,
1066 but the password is used only once and the frontend will be asked for
1067 a new password whenever a request from authenticator requires a
1068 password; this can be used with both EAP-OTP and EAP-GTC
1069 * changed wpa_cli to automatically re-establish connection so that it
1070 does not need to be re-started when wpa_supplicant is terminated and
1072 * improved user data (identity/password/otp) requests through
1073 frontends: process pending EAPOL packets after getting new
1074 information so that full authentication does not need to be
1075 restarted; in addition, send pending requests again whenever a new
1076 frontend is attached
1077 * changed control frontends to use a new directory for socket files to
1078 make it easier for wpa_cli to automatically select between interfaces
1079 and to provide access control for the control interface;
1080 wpa_supplicant.conf: ctrl_interface is now a path
1081 (/var/run/wpa_supplicant is the recommended path) and
1082 ctrl_interface_group can be used to select which group gets access to
1083 the control interface;
1084 wpa_cli: by default, try to connect to the first interface available
1085 in /var/run/wpa_supplicant; this path can be overriden with -p option
1086 and an interface can be selected with -i option (i.e., in most common
1087 cases, wpa_cli does not need to get any arguments)
1088 * added support for LEAP
1089 * added driver interface for Linux ndiswrapper
1090 * added priority option for network blocks in the configuration file;
1091 this allows networks to be grouped based on priority (the scan
1092 results are searched for matches with network blocks in this order)
1095 * sort scan results to improve AP selection
1096 * fixed control interface socket removal for some error cases
1097 * improved scan requesting and authentication timeout
1098 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1100 * PEAP version can now be forced with phase1="peapver=<ver>"
1101 (mostly for testing; by default, the highest version supported by
1102 both the Supplicant and Authentication Server is selected
1104 * added support for madwifi driver (Atheros ar521x)
1105 * added a workaround for cases where AP sets Install Tx/Rx bit for
1106 WPA Group Key messages when pairwise keys are used (without this,
1107 the Group Key would be used for Tx and the AP would drop frames
1109 * added GSM SIM/USIM interface for GSM authentication algorithm for
1110 EAP-SIM; this requires pcsc-lite
1111 * added support for ATMEL AT76C5XXx driver
1112 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1113 does not include key data in the EAPOL-Key frame (i.e., part of
1114 EAP keying material is used as data encryption key)
1115 * added support for using plaintext and static WEP networks
1119 * added support for new EAP authentication methods:
1120 EAP-TTLS/EAP-MD5-Challenge
1122 EAP-TTLS/EAP-MSCHAPv2
1130 EAP-PEAP/MD5-Challenge
1132 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1133 * added support for anonymous identity (to be used when identity is
1134 sent in plaintext; real identity will be used within TLS protected
1135 tunnel (e.g., with EAP-TTLS)
1136 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1137 * added support for requesting identity and password information using
1138 control interface; in other words, the password for EAP-PEAP or
1139 EAP-TTLS does not need to be included in the configuration file since
1140 a frontand (e.g., wpa_cli) can ask it from the user
1141 * improved RSN pre-authentication to use a candidate list and process
1142 all candidates from each scan; not only one per scan
1143 * fixed RSN IE and WPA IE capabilities field parsing
1144 * ignore Tx bit in GTK IE when Pairwise keys are used
1145 * avoid making new scan requests during IEEE 802.1X negotiation
1146 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1147 with TLS support (this replaces the included implementation with
1148 library code to save about 8 kB since the library code is needed
1150 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1151 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1154 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1156 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1157 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1158 - EAP-MD5 (cannot be used with WPA-RADIUS)
1159 [draft-ietf-eap-rfc2284bis-09.txt]
1160 - EAP-TLS [RFC 2716]
1161 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1162 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1163 [draft-kamath-pppext-eap-mschapv2-00.txt]
1164 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1165 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1166 - new configuration file options: eap, identity, password, ca_cert,
1167 client_cert, privatekey, private_key_passwd
1168 - Xsupplicant is not required anymore, but it can be used by
1169 disabling the internal IEEE 802.1X Supplicant with -e command line
1171 - this code is not included in the default build; Makefile need to
1172 be edited for this (uncomment lines for selected functionality)
1173 - EAP-TLS and EAP-PEAP require openssl libraries
1174 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1175 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1176 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1177 EAPOL-Key frames instead of WPA key handshakes)
1178 * added support for IEEE 802.11i/RSN (WPA2)
1179 - improved PTK Key Handshake
1180 - PMKSA caching, pre-authentication
1181 * fixed wpa_supplicant to ignore possible extra data after WPA
1182 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1183 TPTK' error from message 3 of 4-Way Handshake in case the AP
1184 includes extra data after the EAPOL-Key)
1185 * added interface for external programs (frontends) to control
1187 - CLI example (wpa_cli) with interactive mode and command line
1189 - replaced SIGUSR1 status/statistics with the new control interface
1190 * made some feature compile time configurable
1191 - .config file for make
1192 - driver interfaces (hostap, hermes, ..)
1193 - EAPOL/EAP functions
1196 * Initial version of wpa_supplicant
