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)
25 * fixed SHA-256 based key derivation function to match with the
26 standard when using CCMP (for IEEE 802.11r and IEEE 802.11w)
27 (note: this breaks interoperability with previous version) [Bug 307]
30 * added support for Wi-Fi Protected Setup (WPS)
31 (wpa_supplicant can now be configured to act as a WPS Enrollee to
32 enroll credentials for a network using PIN and PBC methods; in
33 addition, wpa_supplicant can act as a wireless WPS Registrar to
34 configure an AP); WPS support can be enabled by adding CONFIG_WPS=y
35 into .config and setting the runtime configuration variables in
36 wpa_supplicant.conf (see WPS section in the example configuration
37 file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to
38 manage WPS negotiation; see README-WPS for more details
39 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
40 * added support for using driver_test over UDP socket
41 * fixed PEAPv0 Cryptobinding interoperability issue with Windows Server
42 2008 NPS; optional cryptobinding is now enabled (again) by default
43 * fixed PSK editing in wpa_gui
44 * changed EAP-GPSK to use the IANA assigned EAP method type 51
45 * added a Windows installer that includes WinPcap and all the needed
46 DLLs; in addition, it set up the registry automatically so that user
47 will only need start wpa_gui to get prompted to start the wpasvc
48 servide and add a new interface if needed through wpa_gui dialog
49 * updated management frame protection to use IEEE 802.11w/D7.0
52 * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
53 (can be used to simulate test SIM/USIM card with a known private key;
54 enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
55 and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
56 * added a new network configuration option, wpa_ptk_rekey, that can be
57 used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
58 against TKIP deficiencies
59 * added an optional mitigation mechanism for certain attacks against
60 TKIP by delaying Michael MIC error reports by a random amount of time
61 between 0 and 60 seconds; this can be enabled with a build option
62 CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
63 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
65 * updated OpenSSL code for EAP-FAST to use an updated version of the
66 session ticket overriding API that was included into the upstream
67 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
68 needed with that version anymore)
69 * updated userspace MLME instructions to match with the current Linux
70 mac80211 implementation; please also note that this can only be used
71 with driver_nl80211.c (the old code from driver_wext.c was removed)
72 * added support (Linux only) for RoboSwitch chipsets (often found in
73 consumer grade routers); driver interface 'roboswitch'
74 * fixed canceling of PMKSA caching when using drivers that generate
75 RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
79 * added support for SHA-256 as X.509 certificate digest when using the
80 internal X.509/TLSv1 implementation
81 * updated management frame protection to use IEEE 802.11w/D6.0
82 * added support for using SHA256-based stronger key derivation for WPA2
84 * fixed FT (IEEE 802.11r) authentication after a failed association to
86 * added support for configuring Phase 2 (inner/tunneled) authentication
87 method with wpa_gui-qt4
90 * added support for EAP Sequences in EAP-FAST Phase 2
91 * added support for using TNC with EAP-FAST
92 * added driver_ps3 for the PS3 Linux wireless driver
93 * added support for optional cryptobinding with PEAPv0
94 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
95 allow fallback to full handshake if server rejects PAC-Opaque
96 * added fragmentation support for EAP-TNC
97 * added support for parsing PKCS #8 formatted private keys into the
98 internal TLS implementation (both PKCS #1 RSA key and PKCS #8
99 encapsulated RSA key can now be used)
100 * added option of using faster, but larger, routines in the internal
101 LibTomMath (for internal TLS implementation) to speed up DH and RSA
102 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
103 * fixed race condition between disassociation event and group key
104 handshake to avoid getting stuck in incorrect state [Bug 261]
105 * fixed opportunistic key caching (proactive_key_caching)
108 * removed 'nai' and 'eappsk' network configuration variables that were
109 previously used for configuring user identity and key for EAP-PSK,
110 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
111 replacement for 'nai' (if old configuration used a separate
112 'identity' value, that would now be configured as
113 'anonymous_identity'). 'password' field is now used as the
114 replacement for 'eappsk' (it can also be set using hexstring to
115 present random binary data)
116 * removed '-w' command line parameter (wait for interface to be added,
117 if needed); cleaner way of handling this functionality is to use an
118 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
119 when an interface is added
120 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
121 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
122 indicating when new scan results become available
123 * added new ctrl_iface command, BSS, to allow scan results to be
124 fetched without hitting the message size limits (this command
125 can be used to iterate through the scan results one BSS at the time)
126 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
127 attributes in EAP-SIM Start/Response when using fast reauthentication
128 * fixed EAPOL not to end up in infinite loop when processing dynamic
129 WEP keys with IEEE 802.1X
130 * fixed problems in getting NDIS events from WMI on Windows 2000
133 * added support for Makefile builds to include debug-log-to-a-file
134 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
135 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
136 lengths properly to avoid potential crash caused by invalid messages
137 * added data structure for storing allocated buffers (struct wpabuf);
138 this does not affect wpa_supplicant usage, but many of the APIs
139 changed and various interfaces (e.g., EAP) is not compatible with old
141 * added support for protecting EAP-AKA/Identity messages with
142 AT_CHECKCODE (optional feature in RFC 4187)
143 * added support for protected result indication with AT_RESULT_IND for
144 EAP-SIM and EAP-AKA (phase1="result_ind=1")
145 * added driver_wext workaround for race condition between scanning and
146 association with drivers that take very long time to scan all
147 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
148 using a longer hardcoded timeout for the scan if the driver supports
149 notifications for scan completion (SIOCGIWSCAN event); this helps,
150 e.g., in cases where wpa_supplicant and madwifi driver ended up in
151 loop where the driver did not even try to associate
152 * stop EAPOL timer tick when no timers are in use in order to reduce
153 power consumption (no need to wake up the process once per second)
155 * added support for privilege separation (run only minimal part of
156 wpa_supplicant functionality as root and rest as unprivileged,
157 non-root process); see 'Privilege separation' in README for details;
158 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
160 * changed scan results data structure to include all information
161 elements to make it easier to support new IEs; old get_scan_result()
162 driver_ops is still supported for backwards compatibility (results
163 are converted internally to the new format), but all drivers should
164 start using the new get_scan_results2() to make them more likely to
165 work with new features
166 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
167 application, i.e., it does not require Qt3Support anymore; Windows
168 binary of wpa_gui.exe is now from this directory and only requires
169 QtCore4.dll and QtGui4.dll libraries
170 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
171 available as a separate package to make wpa_gui installation easier:
172 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
173 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
174 only shared key/password authentication is supported in this version
177 * added support for configuring password as NtPasswordHash
178 (16-byte MD4 hash of password) in hash:<32 hex digits> format
179 * added support for fallback from abbreviated TLS handshake to
180 full handshake when using EAP-FAST (e.g., due to an expired
182 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
183 draft (draft-ietf-emu-eap-gpsk-07.txt)
184 * added support for drivers that take care of RSN 4-way handshake
185 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
186 WPA_ALG_PMK in set_key)
187 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
188 .config); this version supports only ap_scan=2 mode and allow the
189 driver to take care of the 4-way handshake
190 * fixed a buffer overflow in parsing TSF from scan results when using
191 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
193 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
194 * fixed an integer overflow issue in the ASN.1 parser used by the
195 (experimental) internal TLS implementation to avoid a potential
197 * fixed a race condition with -W option (wait for a control interface
198 monitor before starting) that could have caused the first messages to
200 * added support for processing TNCC-TNCS-Messages to report
201 recommendation (allow/none/isolate) when using TNC [Bug 243]
204 * added network configuration parameter 'frequency' for setting
205 initial channel for IBSS (adhoc) networks
206 * added experimental IEEE 802.11r/D6.0 support
207 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
208 * updated EAP-PSK to use the IANA-allocated EAP type 47
209 * fixed EAP-PAX key derivation
210 * fixed EAP-PSK bit ordering of the Flags field
211 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
212 tunnelled identity request (previously, the identifier from the outer
213 method was used, not the tunnelled identifier which could be
215 * added support for fragmentation of outer TLS packets during Phase 2
216 of EAP-PEAP/TTLS/FAST
217 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
218 * added support for EAP-FAST authentication with inner methods that
219 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
220 for PAC provisioning)
221 * added support for authenticated EAP-FAST provisioning
222 * added support for configuring maximum number of EAP-FAST PACs to
223 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
224 * added support for storing EAP-FAST PACs in binary format
225 (fast_pac_format=binary in phase1 string)
226 * fixed dbus ctrl_iface to validate message interface before
227 dispatching to avoid a possible segfault [Bug 190]
228 * fixed PeerKey key derivation to use the correct PRF label
229 * updated Windows binary build to link against OpenSSL 0.9.8d and
230 added support for EAP-FAST
231 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
232 draft (draft-ietf-emu-eap-gpsk-04.txt)
233 * fixed EAP-AKA Notification processing to allow Notification to be
234 processed after AKA Challenge response has been sent
235 * updated to use IEEE 802.11w/D2.0 for management frame protection
237 * fixed EAP-TTLS implementation not to crash on use of freed memory
238 if TLS library initialization fails
239 * added support for EAP-TNC (Trusted Network Connect)
240 (this version implements the EAP-TNC method and EAP-TTLS changes
241 needed to run two methods in sequence (IF-T) and the IF-IMC and
242 IF-TNCCS interfaces from TNCC)
245 * added experimental, integrated TLSv1 client implementation with the
246 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
247 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
248 .config); this can be useful, e.g., if the target system does not
249 have a suitable TLS library and a minimal code size is required
250 (total size of this internal TLS/crypto code is bit under 50 kB on
251 x86 and the crypto code is shared by rest of the supplicant so some
252 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
253 * removed STAKey handshake since PeerKey handshake has replaced it in
254 IEEE 802.11ma and there are no known deployments of STAKey
255 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
256 draft (draft-ietf-emu-eap-gpsk-01.txt)
257 * added preliminary implementation of IEEE 802.11w/D1.0 (management
259 (Note: this requires driver support to work properly.)
260 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
261 * fixed Windows named pipes ctrl_iface to not stop listening for
262 commands if client program opens a named pipe and closes it
263 immediately without sending a command
264 * fixed USIM PIN status determination for the case that PIN is not
265 needed (this allows EAP-AKA to be used with USIM cards that do not
267 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
268 be used with cards that do not support file selection based on
270 * added support for matching the subjectAltName of the authentication
271 server certificate against multiple name components (e.g.,
272 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
273 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
274 affects IEEE 802.1X with dynamic WEP keys)
275 * changed ctrl_iface network configuration 'get' operations to not
276 return password/key material; if these fields are requested, "*"
277 will be returned if the password/key is set, but the value of the
278 parameter is not exposed
281 * added support for building Windows version with UNICODE defined
282 (wide-char functions)
283 * driver_ndis: fixed static WEP configuration to avoid race condition
284 issues with some NDIS drivers between association and setting WEP
286 * driver_ndis: added validation for IELength value in scan results to
287 avoid crashes when using buggy NDIS drivers [Bug 165]
288 * fixed Release|Win32 target in the Visual Studio project files
289 (previously, only Debug|Win32 target was set properly)
290 * changed control interface API call wpa_ctrl_pending() to allow it to
291 return -1 on error (e.g., connection lost); control interface clients
292 will need to make sure that they verify that the value is indeed >0
293 when determining whether there are pending messages
294 * added an alternative control interface backend for Windows targets:
295 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
296 control interface mechanism for Windows builds (previously, UDP to
298 * changed ctrl_interface configuration for UNIX domain sockets:
299 - deprecated ctrl_interface_group variable (it may be removed in
301 - allow both directory and group be configured with ctrl_interface
302 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
303 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
304 case when group is not changed
305 * added support for controlling more than one interface per process in
307 * added a workaround for a case where the AP is using unknown address
308 (e.g., MAC address of the wired interface) as the source address for
309 EAPOL-Key frames; previously, that source address was used as the
310 destination for EAPOL-Key frames and in key derivation; now, BSSID is
311 used even if the source address does not match with it
312 (this resolves an interoperability issue with Thomson SpeedTouch 580)
313 * added a workaround for UDP-based control interface (which was used in
314 Windows builds before this release) to prevent packets with forged
315 addresses from being accepted as local control requests
316 * removed ndis_events.cpp and possibility of using external
317 ndis_events.exe; C version (ndis_events.c) is fully functional and
318 there is no desire to maintain two separate versions of this
320 * ndis_events: Changed NDIS event notification design to use WMI to
321 learn the adapter description through Win32_PnPEntity class; this
322 should fix some cases where the adapter name was not recognized
323 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
325 * fixed selection of the first network in ap_scan=2 mode; previously,
326 wpa_supplicant could get stuck in SCANNING state when only the first
327 network for enabled (e.g., after 'wpa_cli select_network 0')
328 * winsvc: added support for configuring ctrl_interface parameters in
329 registry (ctrl_interface string value in
330 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
331 required to enable control interface (previously, this was hardcoded
333 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
334 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
337 * fixed build with CONFIG_STAKEY=y [Bug 143]
338 * added support for doing MLME (IEEE 802.11 management frame
339 processing) in wpa_supplicant when using Devicescape IEEE 802.11
340 stack (wireless-dev.git tree)
341 * added a new network block configuration option, fragment_size, to
342 configure the maximum EAP fragment size
343 * driver_ndis: Disable WZC automatically for the selected interface to
344 avoid conflicts with two programs trying to control the radio; WZC
345 will be re-enabled (if it was enabled originally) when wpa_supplicant
347 * added an experimental TLSv1 client implementation
348 (CONFIG_TLS=internal) that can be used instead of an external TLS
349 library, e.g., to reduce total size requirement on systems that do
350 not include any TLS library by default (this is not yet complete;
351 basic functionality is there, but certificate validation is not yet
353 * added PeerKey handshake implementation for IEEE 802.11e
354 direct link setup (DLS) to replace STAKey handshake
355 * fixed WPA PSK update through ctrl_iface for the case where the old
356 PSK was derived from an ASCII passphrase and the new PSK is set as
357 a raw PSK (hex string)
358 * added new configuration option for identifying which network block
359 was used (id_str in wpa_supplicant.conf; included on
360 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
361 variable in wpa_cli action scripts; in addition WPA_ID variable is
362 set to the current unique identifier that wpa_supplicant assigned
363 automatically for the network and that can be used with
364 GET_NETWORK/SET_NETWORK ctrl_iface commands)
365 * wpa_cli action script is now called only when the connect/disconnect
366 status changes or when associating with a different network
367 * fixed configuration parser not to remove CCMP from group cipher list
368 if WPA-None (adhoc) is used (pairwise=NONE in that case)
369 * fixed integrated NDIS events processing not to hang the process due
370 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
371 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
372 draft-clancy-emu-eap-shared-secret-00.txt)
373 * added Microsoft Visual Studio 2005 solution and project files for
374 build wpa_supplicant for Windows (see vs2005 subdirectory)
375 * eloop_win: fixed unregistration of Windows events
376 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
377 at the end of RSN pre-authentication and added unregistration of
378 a Windows event to avoid getting eloop_win stuck with an invalid
380 * driver_ndis: added support for selecting AP based on BSSID
381 * added new environmental variable for wpa_cli action scripts:
382 WPA_CTRL_DIR is the current control interface directory
383 * driver_ndis: added support for using NDISUIO instead of WinPcap for
384 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
385 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
386 wpa_supplicant without requiring WinPcap; note that using NDISUIO
387 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
388 only one application to open the device
389 * changed NDIS driver naming to only include device GUID, e.g.,
390 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
391 specific \Device\NPF_ prefix before the GUID; the prefix is still
392 allowed for backwards compatibility, but it is not required anymore
393 when specifying the interface
394 * driver_ndis: re-initialize driver interface is the adapter is removed
395 and re-inserted [Bug 159]
396 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
397 big endian hosts [Bug 146]
400 * fixed EAP-GTC response to include correct user identity when run as
401 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
402 * driver_ndis: Fixed encryption mode configuration for unencrypted
403 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
404 refused to associate with open networks) [Bug 106]
405 * driver_ndis: use BSSID OID polling to detect when IBSS network is
406 formed even when ndis_events code is included since some NDIS drivers
407 do not generate media connect events in IBSS mode
408 * config_winreg: allow global ctrl_interface parameter to be configured
410 * config_winreg: added support for saving configuration data into
412 * added support for controlling network device operational state
413 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
414 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
415 that can use this information)
416 * driver_wext: added support for WE-21 change to SSID configuration
417 * driver_wext: fixed privacy configuration for static WEP keys mode
419 * added an optional driver_ops callback for MLME-SETPROTECTION.request
421 * added support for EAP-SAKE (no EAP method number allocated yet, so
422 this is using the same experimental type 255 as EAP-PSK)
423 * added support for dynamically loading EAP methods (.so files) instead
424 of requiring them to be statically linked in; this is disabled by
425 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
429 * do not try to use USIM APDUs when initializing PC/SC for SIM card
430 access for a network that has not enabled EAP-AKA
431 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
432 v0.5.1 due to the new support for expanded EAP types)
433 * added support for generating EAP Expanded Nak
434 * try to fetch scan results once before requesting new scan when
435 starting up in ap_scan=1 mode (this can speed up initial association
436 a lot with, e.g., madwifi-ng driver)
437 * added support for receiving EAPOL frames from a Linux bridge
438 interface (-bbr0 on command line)
439 * fixed EAPOL re-authentication for sessions that used PMKSA caching
440 * changed EAP method registration to use a dynamic list of methods
441 instead of a static list generated at build time
442 * fixed PMKSA cache deinitialization not to use freed memory when
443 removing PMKSA entries
444 * fixed a memory leak in EAP-TTLS re-authentication
445 * reject WPA/WPA2 message 3/4 if it does not include any valid
447 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
448 if the driver does not support SIOCSIWAUTH
451 * driver_test: added better support for multiple APs and STAs by using
452 a directory with sockets that include MAC address for each device in
453 the name (driver_param=test_dir=/tmp/test)
454 * added support for EAP expanded type (vendor specific EAP methods)
455 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
456 option can be changed if needed
457 * wpa_cli/wpa_gui: skip non-socket files in control directory when
458 using UNIX domain sockets; this avoids selecting an incorrect
459 interface (e.g., a PID file could be in this directory, even though
460 use of this directory for something else than socket files is not
462 * fixed TLS library deinitialization after RSN pre-authentication not
463 to disable TLS library for normal authentication
464 * driver_wext: Remove null-termination from SSID length if the driver
465 used it; some Linux drivers do this and they were causing problems in
466 wpa_supplicant not finding matching configuration block. This change
467 would break a case where the SSID actually ends in '\0', but that is
468 not likely to happen in real use.
469 * fixed PMKSA cache processing not to trigger deauthentication if the
470 current PMKSA cache entry is replaced with a valid new entry
471 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
472 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
475 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
476 * added experimental STAKey handshake implementation for IEEE 802.11e
477 direct link setup (DLS); note: this is disabled by default in both
478 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
480 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
481 decrypt AT_ENCR_DATA attributes correctly
482 * fixed EAP-AKA to allow resynchronization within the same session
483 * made code closer to ANSI C89 standard to make it easier to port to
484 other C libraries and compilers
485 * started moving operating system or C library specific functions into
486 wrapper functions defined in os.h and implemented in os_*.c to make
488 * wpa_supplicant can now be built with Microsoft Visual C++
489 (e.g., with the freely available Toolkit 2003 version or Visual
490 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
491 example makefile for nmake
492 * added support for using Windows registry for command line parameters
493 (CONFIG_MAIN=main_winsvc) and configuration data
494 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
495 contents; this version can be run both as a Windows service and as a
496 normal application; 'wpasvc.exe app' to start as applicant,
497 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
498 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
500 * made it possible to link ndis_events.exe functionality into
501 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
502 * added better support for multiple control interface backends
503 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
504 * fixed PC/SC code to use correct length for GSM AUTH command buffer
505 and to not use pioRecvPci with SCardTransmit() calls; these were not
506 causing visible problems with pcsc-lite, but Windows Winscard.dll
507 refused the previously used parameters; this fixes EAP-SIM and
508 EAP-AKA authentication using SIM/USIM card under Windows
509 * added new event loop implementation for Windows using
510 WaitForMultipleObject() instead of select() in order to allow waiting
511 for non-socket objects; this can be selected with
512 CONFIG_ELOOP=eloop_win in .config
513 * added support for selecting l2_packet implementation in .config
514 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
515 winpcap, freebsd, none)
516 * added new l2_packet implementation for WinPcap
517 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
518 reduce latency in EAPOL receive processing from about 100 ms to about
520 * added support for EAP-FAST key derivation using other ciphers than
521 RC4-128-SHA for authentication and AES128-SHA for provisioning
522 * added support for configuring CA certificate as DER file and as a
524 * fixed private key configuration as configuration blob and added
525 support for using PKCS#12 as a blob
526 * tls_gnutls: added support for using PKCS#12 files; added support for
528 * added support for loading trusted CA certificates from Windows
529 certificate store: ca_cert="cert_store://<name>", where <name> is
530 likely CA (Intermediate CA certificates) or ROOT (root certificates)
531 * added C version of ndis_events.cpp and made it possible to build this
532 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
533 easily on cross-compilation builds
534 * added wpasvc.exe into Windows binary release; this is an alternative
535 version of wpa_supplicant.exe with configuration backend using
536 Windows registry and with the entry point designed to run as a
538 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
539 wpasvc.exe and removed this additional tool from the Windows binary
540 release since it is not needed anymore
541 * load winscard.dll functions dynamically when building with MinGW
542 since MinGW does not yet include winscard library
544 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
545 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
546 and WinPcap to receive frames sent to PAE group address
547 * disable EAP state machine when IEEE 802.1X authentication is not used
548 in order to get rid of bogus "EAP failed" messages
549 * fixed OpenSSL error reporting to go through all pending errors to
550 avoid confusing reports of old errors being reported at later point
552 * fixed configuration file updating to not write empty variables
553 (e.g., proto or key_mgmt) that the file parser would not accept
554 * fixed ADD_NETWORK ctrl_iface command to use the same default values
555 for variables as empty network definitions read from config file
557 * fixed EAP state machine to not discard EAP-Failure messages in many
558 cases (e.g., during TLS handshake)
559 * fixed a infinite loop in private key reading if the configured file
560 cannot be parsed successfully
561 * driver_madwifi: added support for madwifi-ng
562 * wpa_gui: do not display password/PSK field contents
563 * wpa_gui: added CA certificate configuration
564 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
565 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
566 the new AP is using different WPA/RSN IE
567 * use longer timeout for IEEE 802.11 association to avoid problems with
568 drivers that may take more than five second to associate
571 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
572 RSN IE, but WPA IE would match with wpa_supplicant configuration
573 * added support for named configuration blobs in order to avoid having
574 to use file system for external files (e.g., certificates);
575 variables can be set to "blob://<blob name>" instead of file path to
576 use a named blob; supported fields: pac_file, client_cert,
578 * fixed RSN pre-authentication (it was broken in the clean up of WPA
579 state machine interface in v0.4.5)
580 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
581 sure the driver configures broadcast decryption correctly
582 * added ca_path (and ca_path2) configuration variables that can be used
583 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
584 system-wide trusted CA list
585 * added support for starting wpa_supplicant without a configuration
586 file (-C argument must be used to set ctrl_interface parameter for
587 this case; in addition, -p argument can be used to provide
588 driver_param; these new arguments can also be used with a
589 configuration to override the values from the configuration)
590 * added global control interface that can be optionally used for adding
591 and removing network interfaces dynamically (-g command line argument
592 for both wpa_supplicant and wpa_cli) without having to restart
593 wpa_supplicant process
595 - try to save configuration whenever something is modified
596 - added WEP key configuration
597 - added possibility to edit the current network configuration
598 * driver_ndis: fixed driver polling not to increase frequency on each
599 received EAPOL frame due to incorrectly cancelled timeout
600 * added simple configuration file examples (in examples subdirectory)
601 * fixed driver_wext.c to filter wireless events based on ifindex to
602 avoid interfaces receiving events from other interfaces
603 * delay sending initial EAPOL-Start couple of seconds to speed up
604 authentication for the most common case of Authenticator starting
605 EAP authentication immediately after association
608 * added a workaround for clearing keys with ndiswrapper to allow
609 roaming from WPA enabled AP to plaintext one
610 * added docbook documentation (doc/docbook) that can be used to
611 generate, e.g., man pages
612 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
613 PF_PACKET in order to prepare for network devices that do not use
614 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
615 * use receipt of EAPOL-Key frame as a lower layer success indication
616 for EAP state machine to allow recovery from dropped EAP-Success
618 * cleaned up internal EAPOL frame processing by not including link
619 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
620 header is added only when transmitted the frame; this makes it easier
621 to use wpa_supplicant on link layers that use different header than
623 * updated EAP-PSK to use draft 9 by default since this can now be
624 tested with hostapd; removed support for draft 3, including
625 server_nai configuration option from network blocks
626 * driver_wired: add PAE address to the multicast address list in order
627 to be able to receive EAPOL frames with drivers that do not include
628 these multicast addresses by default
629 * driver_wext: add support for WE-19
630 * added support for multiple configuration backends (CONFIG_BACKEND
631 option); currently, only 'file' is supported (i.e., the format used
632 in wpa_supplicant.conf)
633 * added support for updating configuration ('wpa_cli save_config');
634 this is disabled by default and can be enabled with global
635 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
636 and wpa_gui to store the configuration changes in a permanent store
637 * added GET_NETWORK ctrl_iface command
638 (e.g., 'wpa_cli get_network 0 ssid')
641 * replaced OpenSSL patch for EAP-FAST support
642 (openssl-tls-extensions.patch) with a more generic and correct
643 patch (the new patch is not compatible with the previous one, so the
644 OpenSSL library will need to be patched with the new patch in order
645 to be able to build wpa_supplicant with EAP-FAST support)
646 * added support for using Windows certificate store (through CryptoAPI)
647 for client certificate and private key operations (EAP-TLS)
648 (see wpa_supplicant.conf for more information on how to configure
649 this with private_key)
650 * ported wpa_gui to Windows
651 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
652 built with the open source version of the Qt4 for Windows
653 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
654 with drivers that do not support WPA
655 * ndis_events: fixed Windows 2000 support
656 * added support for enabling/disabling networks from the list of all
657 configured networks ('wpa_cli enable_network <network id>' and
658 'wpa_cli disable_network <network id>')
659 * added support for adding and removing network from the current
660 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
661 <network id>'); added networks are disabled by default and they can
662 be enabled with enable_network command once the configuration is done
663 for the new network; note: configuration file is not yet updated, so
664 these new networks are lost when wpa_supplicant is restarted
665 * added support for setting network configuration parameters through
666 the control interface, for example:
667 wpa_cli set_network 0 ssid "\"my network\""
668 * fixed parsing of strings that include both " and # within double
669 quoted area (e.g., "start"#end")
670 * added EAP workaround for PEAP session resumption: allow outer,
671 i.e., not tunneled, EAP-Success to terminate session since; this can
672 be disabled with eap_workaround=0
673 (this was allowed for PEAPv1 before, but now it is also allowed for
674 PEAPv0 since at least one RADIUS authentication server seems to be
675 doing this for PEAPv0, too)
676 * wpa_gui: added preliminary support for adding new networks to the
677 wpa_supplicant configuration (double click on the scan results to
678 open network configuration)
681 * removed interface for external EAPOL/EAP supplicant (e.g.,
682 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
683 anymore and is unlikely to be used by anyone
684 * driver_ndis: fixed WinPcap 3.0 support
685 * fixed build with CONFIG_DNET_PCAP=y on Linux
686 * l2_packet: moved different implementations into separate files
690 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
691 (note: ipw2100-1.1.0 is likely to require an update to work with
693 * added support for using ap_scan=2 mode with multiple network blocks;
694 wpa_supplicant will go through the networks one by one until the
695 driver reports a successful association; this uses the same order for
696 networks as scan_ssid=1 scans, i.e., the priority field is ignored
697 and the network block order in the file is used instead
698 * fixed a potential issue in RSN pre-authentication ending up using
699 freed memory if pre-authentication times out
700 * added support for matching alternative subject name extensions of the
701 authentication server certificate; new configuration variables
702 altsubject_match and altsubject_match2
703 * driver_ndis: added support for IEEE 802.1X authentication with wired
705 * added support for querying private key password (EAP-TLS) through the
706 control interface (wpa_cli/wpa_gui) if one is not included in the
708 * driver_broadcom: fixed couple of memory leaks in scan result
710 * EAP-PAX is now registered as EAP type 46
711 * fixed EAP-PAX MAC calculation
712 * fixed EAP-PAX CK and ICK key derivation
713 * added support for using password with EAP-PAX (as an alternative to
714 entering key with eappsk); SHA-1 hash of the password will be used as
716 * added support for arbitrary driver interface parameters through the
717 configuration file with a new driver_param field; this adds a new
718 driver_ops function set_param()
719 * added possibility to override l2_packet module with driver interface
720 API (new send_eapol handler); this can be used to implement driver
721 specific TX/RX functions for EAPOL frames
722 * fixed ctrl_interface_group processing for the case where gid is
723 entered as a number, not group name
724 * driver_test: added support for testing hostapd with wpa_supplicant
725 by using test driver interface without any kernel drivers or network
729 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
730 packets to be encrypted; this was apparently broken by the changed
731 ioctl order in v0.4.0
732 * driver_madwifi: added preliminary support for compiling against 'BSD'
733 branch of madwifi CVS tree
734 * added support for EAP-MSCHAPv2 password retries within the same EAP
735 authentication session
736 * added support for password changes with EAP-MSCHAPv2 (used when the
737 password has expired)
738 * added support for reading additional certificates from PKCS#12 files
739 and adding them to the certificate chain
740 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
742 * fixed a possible double free in EAP-TTLS fast-reauthentication when
743 identity or password is entered through control interface
744 * display EAP Notification messages to user through control interface
745 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
746 * added GUI version of wpa_cli, wpa_gui; this is not build
747 automatically with 'make'; use 'make wpa_gui' to build (this requires
748 Qt development tools)
749 * added 'disconnect' command to control interface for setting
750 wpa_supplicant in state where it will not associate before
751 'reassociate' command has been used
752 * added support for selecting a network from the list of all configured
753 networks ('wpa_cli select_network <network id>'; this disabled all
754 other networks; to re-enable, 'wpa_cli select_network any')
755 * added support for getting scan results through control interface
756 * added EAP workaround for PEAPv1 session resumption: allow outer,
757 i.e., not tunneled, EAP-Success to terminate session since; this can
758 be disabled with eap_workaround=0
760 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
761 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
762 used to reduce the size of the wpa_supplicant considerably if
763 debugging code is not needed
764 * fixed EAPOL-Key validation to drop packets with invalid Key Data
765 Length; such frames could have crashed wpa_supplicant due to buffer
767 * added support for wired authentication (IEEE 802.1X on wired
768 Ethernet); driver interface 'wired'
769 * obsoleted set_wpa() handler in the driver interface API (it can be
770 replaced by moving enable/disable functionality into init()/deinit())
771 (calls to set_wpa() are still present for backwards compatibility,
772 but they may be removed in the future)
773 * driver_madwifi: fixed association in plaintext mode
774 * modified the EAP workaround that accepts EAP-Success with incorrect
775 Identifier to be even less strict about verification in order to
776 interoperate with some authentication servers
777 * added support for sending TLS alerts
778 * added support for 'any' SSID wildcard; if ssid is not configured or
779 is set to an empty string, any SSID will be accepted for non-WPA AP
780 * added support for asking PIN (for SIM) from frontends (e.g.,
781 wpa_cli); if a PIN is needed, but not included in the configuration
782 file, a control interface request is sent and EAP processing is
783 delayed until the PIN is available
784 * added support for using external devices (e.g., a smartcard) for
785 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
786 new wpa_supplicant.conf variables:
787 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
788 - network: engine, engine_id, key_id
789 * added experimental support for EAP-PAX
790 * added monitor mode for wpa_cli (-a<path to a program to run>) that
791 allows external commands (e.g., shell scripts) to be run based on
792 wpa_supplicant events, e.g., when authentication has been completed
793 and data connection is ready; other related wpa_cli arguments:
794 -B (run in background), -P (write PID file); wpa_supplicant has a new
795 command line argument (-W) that can be used to make it wait until a
796 control interface command is received in order to avoid missing
798 * added support for opportunistic WPA2 PMKSA key caching (disabled by
799 default, can be enabled with proactive_key_caching=1)
800 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
801 Authenticator rejects PMKSA caching attempt and the driver is not
802 using assoc_info events
803 * added -P<pid file> argument for wpa_supplicant to write the current
804 process id into a file
806 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
807 * added new phase1 option parameter, include_tls_length=1, to force
808 wpa_supplicant to add TLS Message Length field to all TLS messages
809 even if the packet is not fragmented; this may be needed with some
810 authentication servers
811 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
812 using drivers that take care of AP selection (e.g., when using
814 * fixed reprocessing of pending request after ctrl_iface requests for
815 identity/password/otp
816 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
817 EAP-PEAP and EAP-TTLS
818 * all drivers using driver_wext: set interface up and select Managed
819 mode when starting wpa_supplicant; set interface down when exiting
820 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
821 ipw2100 and ipw2200; please note that this also changed the
822 configuration variable in .config to CONFIG_DRIVER_IPW
825 * fixed a busy loop introduced in v0.3.5 for scan result processing
826 when no matching AP is found
829 * added a workaround for an interoperability issue with a Cisco AP
831 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
832 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
833 retransmission of dropped frames)
834 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
835 (e.g., segfault when processing EAPOL-Key frames)
836 * fixed EAP workaround and fast reauthentication configuration for
837 RSN pre-authentication; previously these were disabled and
838 pre-authentication would fail if the used authentication server
839 requires EAP workarounds
840 * added support for blacklisting APs that fail or timeout
841 authentication in ap_scan=1 mode so that all APs are tried in cases
842 where the ones with strongest signal level are failing authentication
843 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
844 authentication attempt
845 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
846 in the previous authentication (previously, only Phase 1 success was
850 * added preliminary support for IBSS (ad-hoc) mode configuration
851 (mode=1 in network block); this included a new key_mgmt mode
852 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
853 key management; see wpa_supplicant.conf for more details and an
854 example on how to configure this (note: this is currently implemented
855 only for driver_hostapd.c, but the changes should be trivial to add
856 in associate() handler for other drivers, too (assuming the driver
858 * added preliminary port for native Windows (i.e., no cygwin) using
862 * added optional support for GNU Readline and History Libraries for
863 wpa_cli (CONFIG_READLINE)
864 * cleaned up EAP state machine <-> method interface and number of
865 small problems with error case processing not terminating on
866 EAP-Failure but waiting for timeout
867 * added couple of workarounds for interoperability issues with a
868 Cisco AP when using WPA2
869 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
870 Note: This requires a patch for openssl to add support for TLS
871 extensions and number of workarounds for operations without
872 certificates. Proof of concept type of experimental patch is
873 included in openssl-tls-extensions.patch.
876 * fixed private key loading for cases where passphrase is not set
877 * fixed Windows/cygwin L2 packet handler freeing; previous version
878 could cause a segfault when RSN pre-authentication was completed
879 * added support for PMKSA caching with drivers that generate RSN IEs
880 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
881 but similar code can be easily added to driver_ndiswrapper.c once
882 ndiswrapper gets full support for RSN PMKSA caching
883 * improved recovery from PMKID mismatches by requesting full EAP
884 authentication in case of failed PMKSA caching attempt
885 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
886 (this requires that ndis_events is ran while wpa_supplicant is
888 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
889 * added support for driver interfaces to replace the interface name
890 based on driver/OS specific mapping, e.g., in case of driver_ndis,
891 this allows the beginning of the adapter description to be used as
893 * added support for CR+LF (Windows-style) line ends in configuration
895 * driver_ndis: enable radio before starting scanning, disable radio
897 * modified association event handler to set portEnabled = FALSE before
898 clearing port Valid in order to reset EAP state machine and avoid
899 problems with new authentication getting ignored because of state
900 machines ending up in AUTHENTICATED/SUCCESS state based on old
902 * added support for driver events to add PMKID candidates in order to
903 allow drivers to give priority to most likely roaming candidates
904 * driver_hostap: moved PrivacyInvoked configuration to associate()
905 function so that this will not be set for plaintext connections
906 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
907 interface can distinguish plaintext and IEEE 802.1X (no WPA)
909 * fixed static WEP key configuration to use broadcast/default type for
910 all keys (previously, the default TX key was configured as pairwise/
912 * driver_ndis: added legacy WPA capability detection for non-WPA2
914 * added support for setting static WEP keys for IEEE 802.1X without
915 dynamic WEP keying (eapol_flags=0)
918 * added support for reading PKCS#12 (PFX) files (as a replacement for
919 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
920 * fixed compilation with CONFIG_PCSC=y
921 * added new ap_scan mode, ap_scan=2, for drivers that take care of
922 association, but need to be configured with security policy and SSID,
923 e.g., ndiswrapper and NDIS driver; this mode should allow such
924 drivers to work with hidden SSIDs and optimized roaming; when
925 ap_scan=2 is used, only the first network block in the configuration
926 file is used and this configuration should have explicit security
927 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
928 group, proto variables
929 * added experimental port of wpa_supplicant for Windows
930 - driver_ndis.c driver interface (NDIS OIDs)
931 - currently, this requires cygwin and WinPcap
932 - small utility, win_if_list, can be used to get interface name
933 * control interface can now be removed at build time; add
934 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
935 * optional Xsupplicant interface can now be removed at build time;
936 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
937 * added auth_alg to driver interface associate() parameters to make it
938 easier for drivers to configure authentication algorithm as part of
941 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
942 * driver_broadcom: added new driver interface for Broadcom wl.o driver
943 (a generic driver for Broadcom IEEE 802.11a/g cards)
944 * wpa_cli: fixed parsing of -p <path> command line argument
945 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
946 ACK, not tunneled EAP-Success (of which only the first byte was
947 actually send due to a bug in previous code); this seems to
948 interoperate with most RADIUS servers that implements PEAPv1
949 * PEAPv1: added support for terminating PEAP authentication on tunneled
950 EAP-Success message; this can be configured by adding
951 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
952 (some RADIUS servers require this whereas others require a tunneled
954 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
955 the old label for key derivation; previously, the default was 1,
956 but it looks like most existing PEAPv1 implementations use the old
957 label which is thus more suitable default option
958 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
959 * fixed parsing of wep_tx_keyidx
960 * added support for configuring list of allowed Phase 2 EAP types
961 (for both EAP-PEAP and EAP-TTLS) instead of only one type
962 * added support for configuring IEEE 802.11 authentication algorithm
963 (auth_alg; mainly for using Shared Key authentication with static
965 * added support for EAP-AKA (with UMTS SIM)
966 * fixed couple of errors in PCSC handling that could have caused
967 random-looking errors for EAP-SIM
968 * added support for EAP-SIM pseudonyms and fast re-authentication
969 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
971 * added support for EAP-SIM with two challanges
972 (phase1="sim_min_num_chal=3" can be used to require three challenges)
973 * added support for configuring DH/DSA parameters for an ephemeral DH
974 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
975 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
976 and optional DH key exchange to achieve forward secracy with RSA keys
977 * added support for matching subject of the authentication server
978 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
979 configuration variables subject_match and subject_match2
980 * changed SSID configuration in driver_wext.c (used by many driver
981 interfaces) to use ssid_len+1 as the length for SSID since some Linux
983 * fixed couple of unaligned reads in scan result parsing to fix WPA
984 connection on some platforms (e.g., ARM)
985 * added driver interface for Intel ipw2100 driver
986 * added support for LEAP with WPA
987 * added support for larger scan results report (old limit was 4 kB of
988 data, i.e., about 35 or so APs) when using Linux wireless extensions
990 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
991 only if there is a PMKSA cache entry for the current AP
992 * fixed error handling for case where reading of scan results fails:
993 must schedule a new scan or wpa_supplicant will remain waiting
995 * changed debug output to remove shared password/key material by
996 default; all key information can be included with -K command line
997 argument to match the previous behavior
998 * added support for timestamping debug log messages (disabled by
999 default, can be enabled with -t command line argument)
1000 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
1001 if keys are not configured to be used; this fixes IEEE 802.1X mode
1002 with drivers that use this information to configure whether Privacy
1003 bit can be in Beacon frames (e.g., ndiswrapper)
1004 * avoid clearing driver keys if no keys have been configured since last
1005 key clear request; this seems to improve reliability of group key
1006 handshake for ndiswrapper & NDIS driver which seems to be suffering
1007 of some kind of timing issue when the keys are cleared again after
1009 * changed driver interface API:
1010 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
1011 version is being used (now, this is set to 2; previously, it was
1013 - pass pointer to private data structure to all calls
1014 - the new API is not backwards compatible; all in-tree driver
1015 interfaces has been converted to the new API
1016 * added support for controlling multiple interfaces (radios) per
1017 wpa_supplicant process; each interface needs to be listed on the
1018 command line (-c, -i, -D arguments) with -N as a separator
1019 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
1020 * added a workaround for EAP servers that incorrectly use same Id for
1021 sequential EAP packets
1022 * changed libpcap/libdnet configuration to use .config variable,
1023 CONFIG_DNET_PCAP, instead of requiring Makefile modification
1024 * improved downgrade attack detection in IE verification of msg 3/4:
1025 verify both WPA and RSN IEs, if present, not only the selected one;
1026 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
1027 Probe Response frame, and RSN is enabled in wpa_supplicant
1029 * fixed WPA msg 3/4 processing to allow Key Data field contain other
1030 IEs than just one WPA IE
1031 * added support for FreeBSD and driver interface for the BSD net80211
1032 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
1033 required kernel mods have not yet been committed
1034 * made EAP workarounds configurable; enabled by default, can be
1035 disabled with network block option eap_workaround=0
1037 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
1038 * resolved couple of interoperability issues with EAP-PEAPv1 and
1039 Phase 2 (inner EAP) fragment reassembly
1040 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
1041 AP is using non-zero key index for the unicast key and key index zero
1042 for the broadcast key
1043 * driver_hostap: fixed IEEE 802.1X WEP key updates and
1044 re-authentication by allowing unencrypted EAPOL frames when not using
1046 * added a new driver interface, 'wext', which uses only standard,
1047 driver independent functionality in Linux wireless extensions;
1048 currently, this can be used only for non-WPA IEEE 802.1X mode, but
1049 eventually, this is to be extended to support full WPA/WPA2 once
1050 Linux wireless extensions get support for this
1051 * added support for mode in which the driver is responsible for AP
1052 scanning and selection; this is disabled by default and can be
1053 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
1054 this mode can be used, e.g., with generic 'wext' driver interface to
1055 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
1056 supporting wireless extensions.
1057 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
1058 operation with an AP that does not include SSID in the Beacon frames)
1059 * added support for new EAP authentication methods:
1060 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
1061 * added support for asking one-time-passwords from frontends (e.g.,
1062 wpa_cli); this 'otp' command works otherwise like 'password' command,
1063 but the password is used only once and the frontend will be asked for
1064 a new password whenever a request from authenticator requires a
1065 password; this can be used with both EAP-OTP and EAP-GTC
1066 * changed wpa_cli to automatically re-establish connection so that it
1067 does not need to be re-started when wpa_supplicant is terminated and
1069 * improved user data (identity/password/otp) requests through
1070 frontends: process pending EAPOL packets after getting new
1071 information so that full authentication does not need to be
1072 restarted; in addition, send pending requests again whenever a new
1073 frontend is attached
1074 * changed control frontends to use a new directory for socket files to
1075 make it easier for wpa_cli to automatically select between interfaces
1076 and to provide access control for the control interface;
1077 wpa_supplicant.conf: ctrl_interface is now a path
1078 (/var/run/wpa_supplicant is the recommended path) and
1079 ctrl_interface_group can be used to select which group gets access to
1080 the control interface;
1081 wpa_cli: by default, try to connect to the first interface available
1082 in /var/run/wpa_supplicant; this path can be overriden with -p option
1083 and an interface can be selected with -i option (i.e., in most common
1084 cases, wpa_cli does not need to get any arguments)
1085 * added support for LEAP
1086 * added driver interface for Linux ndiswrapper
1087 * added priority option for network blocks in the configuration file;
1088 this allows networks to be grouped based on priority (the scan
1089 results are searched for matches with network blocks in this order)
1092 * sort scan results to improve AP selection
1093 * fixed control interface socket removal for some error cases
1094 * improved scan requesting and authentication timeout
1095 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1097 * PEAP version can now be forced with phase1="peapver=<ver>"
1098 (mostly for testing; by default, the highest version supported by
1099 both the Supplicant and Authentication Server is selected
1101 * added support for madwifi driver (Atheros ar521x)
1102 * added a workaround for cases where AP sets Install Tx/Rx bit for
1103 WPA Group Key messages when pairwise keys are used (without this,
1104 the Group Key would be used for Tx and the AP would drop frames
1106 * added GSM SIM/USIM interface for GSM authentication algorithm for
1107 EAP-SIM; this requires pcsc-lite
1108 * added support for ATMEL AT76C5XXx driver
1109 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1110 does not include key data in the EAPOL-Key frame (i.e., part of
1111 EAP keying material is used as data encryption key)
1112 * added support for using plaintext and static WEP networks
1116 * added support for new EAP authentication methods:
1117 EAP-TTLS/EAP-MD5-Challenge
1119 EAP-TTLS/EAP-MSCHAPv2
1127 EAP-PEAP/MD5-Challenge
1129 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1130 * added support for anonymous identity (to be used when identity is
1131 sent in plaintext; real identity will be used within TLS protected
1132 tunnel (e.g., with EAP-TTLS)
1133 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1134 * added support for requesting identity and password information using
1135 control interface; in other words, the password for EAP-PEAP or
1136 EAP-TTLS does not need to be included in the configuration file since
1137 a frontand (e.g., wpa_cli) can ask it from the user
1138 * improved RSN pre-authentication to use a candidate list and process
1139 all candidates from each scan; not only one per scan
1140 * fixed RSN IE and WPA IE capabilities field parsing
1141 * ignore Tx bit in GTK IE when Pairwise keys are used
1142 * avoid making new scan requests during IEEE 802.1X negotiation
1143 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1144 with TLS support (this replaces the included implementation with
1145 library code to save about 8 kB since the library code is needed
1147 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1148 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1151 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1153 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1154 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1155 - EAP-MD5 (cannot be used with WPA-RADIUS)
1156 [draft-ietf-eap-rfc2284bis-09.txt]
1157 - EAP-TLS [RFC 2716]
1158 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1159 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1160 [draft-kamath-pppext-eap-mschapv2-00.txt]
1161 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1162 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1163 - new configuration file options: eap, identity, password, ca_cert,
1164 client_cert, privatekey, private_key_passwd
1165 - Xsupplicant is not required anymore, but it can be used by
1166 disabling the internal IEEE 802.1X Supplicant with -e command line
1168 - this code is not included in the default build; Makefile need to
1169 be edited for this (uncomment lines for selected functionality)
1170 - EAP-TLS and EAP-PEAP require openssl libraries
1171 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1172 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1173 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1174 EAPOL-Key frames instead of WPA key handshakes)
1175 * added support for IEEE 802.11i/RSN (WPA2)
1176 - improved PTK Key Handshake
1177 - PMKSA caching, pre-authentication
1178 * fixed wpa_supplicant to ignore possible extra data after WPA
1179 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1180 TPTK' error from message 3 of 4-Way Handshake in case the AP
1181 includes extra data after the EAPOL-Key)
1182 * added interface for external programs (frontends) to control
1184 - CLI example (wpa_cli) with interactive mode and command line
1186 - replaced SIGUSR1 status/statistics with the new control interface
1187 * made some feature compile time configurable
1188 - .config file for make
1189 - driver interfaces (hostap, hermes, ..)
1190 - EAPOL/EAP functions
1193 * Initial version of wpa_supplicant
