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
21 * added support for Wi-Fi Protected Setup (WPS)
22 (wpa_supplicant can now be configured to act as a WPS Enrollee to
23 enroll credentials for a network using PIN and PBC methods; in
24 addition, wpa_supplicant can act as a wireless WPS Registrar to
25 configure an AP); WPS support can be enabled by adding CONFIG_WPS=y
26 into .config and setting the runtime configuration variables in
27 wpa_supplicant.conf (see WPS section in the example configuration
28 file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to
29 manage WPS negotiation; see README-WPS for more details
30 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
31 * added support for using driver_test over UDP socket
32 * fixed PEAPv0 Cryptobinding interoperability issue with Windows Server
33 2008 NPS; optional cryptobinding is now enabled (again) by default
34 * fixed PSK editing in wpa_gui
35 * changed EAP-GPSK to use the IANA assigned EAP method type 51
36 * added a Windows installer that includes WinPcap and all the needed
37 DLLs; in addition, it set up the registry automatically so that user
38 will only need start wpa_gui to get prompted to start the wpasvc
39 servide and add a new interface if needed through wpa_gui dialog
40 * updated management frame protection to use IEEE 802.11w/D7.0
43 * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
44 (can be used to simulate test SIM/USIM card with a known private key;
45 enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
46 and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
47 * added a new network configuration option, wpa_ptk_rekey, that can be
48 used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
49 against TKIP deficiencies
50 * added an optional mitigation mechanism for certain attacks against
51 TKIP by delaying Michael MIC error reports by a random amount of time
52 between 0 and 60 seconds; this can be enabled with a build option
53 CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
54 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
56 * updated OpenSSL code for EAP-FAST to use an updated version of the
57 session ticket overriding API that was included into the upstream
58 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
59 needed with that version anymore)
60 * updated userspace MLME instructions to match with the current Linux
61 mac80211 implementation; please also note that this can only be used
62 with driver_nl80211.c (the old code from driver_wext.c was removed)
63 * added support (Linux only) for RoboSwitch chipsets (often found in
64 consumer grade routers); driver interface 'roboswitch'
65 * fixed canceling of PMKSA caching when using drivers that generate
66 RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
70 * added support for SHA-256 as X.509 certificate digest when using the
71 internal X.509/TLSv1 implementation
72 * updated management frame protection to use IEEE 802.11w/D6.0
73 * added support for using SHA256-based stronger key derivation for WPA2
75 * fixed FT (IEEE 802.11r) authentication after a failed association to
77 * added support for configuring Phase 2 (inner/tunneled) authentication
78 method with wpa_gui-qt4
81 * added support for EAP Sequences in EAP-FAST Phase 2
82 * added support for using TNC with EAP-FAST
83 * added driver_ps3 for the PS3 Linux wireless driver
84 * added support for optional cryptobinding with PEAPv0
85 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
86 allow fallback to full handshake if server rejects PAC-Opaque
87 * added fragmentation support for EAP-TNC
88 * added support for parsing PKCS #8 formatted private keys into the
89 internal TLS implementation (both PKCS #1 RSA key and PKCS #8
90 encapsulated RSA key can now be used)
91 * added option of using faster, but larger, routines in the internal
92 LibTomMath (for internal TLS implementation) to speed up DH and RSA
93 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
94 * fixed race condition between disassociation event and group key
95 handshake to avoid getting stuck in incorrect state [Bug 261]
96 * fixed opportunistic key caching (proactive_key_caching)
99 * removed 'nai' and 'eappsk' network configuration variables that were
100 previously used for configuring user identity and key for EAP-PSK,
101 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
102 replacement for 'nai' (if old configuration used a separate
103 'identity' value, that would now be configured as
104 'anonymous_identity'). 'password' field is now used as the
105 replacement for 'eappsk' (it can also be set using hexstring to
106 present random binary data)
107 * removed '-w' command line parameter (wait for interface to be added,
108 if needed); cleaner way of handling this functionality is to use an
109 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
110 when an interface is added
111 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
112 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
113 indicating when new scan results become available
114 * added new ctrl_iface command, BSS, to allow scan results to be
115 fetched without hitting the message size limits (this command
116 can be used to iterate through the scan results one BSS at the time)
117 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
118 attributes in EAP-SIM Start/Response when using fast reauthentication
119 * fixed EAPOL not to end up in infinite loop when processing dynamic
120 WEP keys with IEEE 802.1X
121 * fixed problems in getting NDIS events from WMI on Windows 2000
124 * added support for Makefile builds to include debug-log-to-a-file
125 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
126 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
127 lengths properly to avoid potential crash caused by invalid messages
128 * added data structure for storing allocated buffers (struct wpabuf);
129 this does not affect wpa_supplicant usage, but many of the APIs
130 changed and various interfaces (e.g., EAP) is not compatible with old
132 * added support for protecting EAP-AKA/Identity messages with
133 AT_CHECKCODE (optional feature in RFC 4187)
134 * added support for protected result indication with AT_RESULT_IND for
135 EAP-SIM and EAP-AKA (phase1="result_ind=1")
136 * added driver_wext workaround for race condition between scanning and
137 association with drivers that take very long time to scan all
138 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
139 using a longer hardcoded timeout for the scan if the driver supports
140 notifications for scan completion (SIOCGIWSCAN event); this helps,
141 e.g., in cases where wpa_supplicant and madwifi driver ended up in
142 loop where the driver did not even try to associate
143 * stop EAPOL timer tick when no timers are in use in order to reduce
144 power consumption (no need to wake up the process once per second)
146 * added support for privilege separation (run only minimal part of
147 wpa_supplicant functionality as root and rest as unprivileged,
148 non-root process); see 'Privilege separation' in README for details;
149 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
151 * changed scan results data structure to include all information
152 elements to make it easier to support new IEs; old get_scan_result()
153 driver_ops is still supported for backwards compatibility (results
154 are converted internally to the new format), but all drivers should
155 start using the new get_scan_results2() to make them more likely to
156 work with new features
157 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
158 application, i.e., it does not require Qt3Support anymore; Windows
159 binary of wpa_gui.exe is now from this directory and only requires
160 QtCore4.dll and QtGui4.dll libraries
161 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
162 available as a separate package to make wpa_gui installation easier:
163 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
164 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
165 only shared key/password authentication is supported in this version
168 * added support for configuring password as NtPasswordHash
169 (16-byte MD4 hash of password) in hash:<32 hex digits> format
170 * added support for fallback from abbreviated TLS handshake to
171 full handshake when using EAP-FAST (e.g., due to an expired
173 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
174 draft (draft-ietf-emu-eap-gpsk-07.txt)
175 * added support for drivers that take care of RSN 4-way handshake
176 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
177 WPA_ALG_PMK in set_key)
178 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
179 .config); this version supports only ap_scan=2 mode and allow the
180 driver to take care of the 4-way handshake
181 * fixed a buffer overflow in parsing TSF from scan results when using
182 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
184 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
185 * fixed an integer overflow issue in the ASN.1 parser used by the
186 (experimental) internal TLS implementation to avoid a potential
188 * fixed a race condition with -W option (wait for a control interface
189 monitor before starting) that could have caused the first messages to
191 * added support for processing TNCC-TNCS-Messages to report
192 recommendation (allow/none/isolate) when using TNC [Bug 243]
195 * added network configuration parameter 'frequency' for setting
196 initial channel for IBSS (adhoc) networks
197 * added experimental IEEE 802.11r/D6.0 support
198 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
199 * updated EAP-PSK to use the IANA-allocated EAP type 47
200 * fixed EAP-PAX key derivation
201 * fixed EAP-PSK bit ordering of the Flags field
202 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
203 tunnelled identity request (previously, the identifier from the outer
204 method was used, not the tunnelled identifier which could be
206 * added support for fragmentation of outer TLS packets during Phase 2
207 of EAP-PEAP/TTLS/FAST
208 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
209 * added support for EAP-FAST authentication with inner methods that
210 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
211 for PAC provisioning)
212 * added support for authenticated EAP-FAST provisioning
213 * added support for configuring maximum number of EAP-FAST PACs to
214 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
215 * added support for storing EAP-FAST PACs in binary format
216 (fast_pac_format=binary in phase1 string)
217 * fixed dbus ctrl_iface to validate message interface before
218 dispatching to avoid a possible segfault [Bug 190]
219 * fixed PeerKey key derivation to use the correct PRF label
220 * updated Windows binary build to link against OpenSSL 0.9.8d and
221 added support for EAP-FAST
222 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
223 draft (draft-ietf-emu-eap-gpsk-04.txt)
224 * fixed EAP-AKA Notification processing to allow Notification to be
225 processed after AKA Challenge response has been sent
226 * updated to use IEEE 802.11w/D2.0 for management frame protection
228 * fixed EAP-TTLS implementation not to crash on use of freed memory
229 if TLS library initialization fails
230 * added support for EAP-TNC (Trusted Network Connect)
231 (this version implements the EAP-TNC method and EAP-TTLS changes
232 needed to run two methods in sequence (IF-T) and the IF-IMC and
233 IF-TNCCS interfaces from TNCC)
236 * added experimental, integrated TLSv1 client implementation with the
237 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
238 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
239 .config); this can be useful, e.g., if the target system does not
240 have a suitable TLS library and a minimal code size is required
241 (total size of this internal TLS/crypto code is bit under 50 kB on
242 x86 and the crypto code is shared by rest of the supplicant so some
243 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
244 * removed STAKey handshake since PeerKey handshake has replaced it in
245 IEEE 802.11ma and there are no known deployments of STAKey
246 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
247 draft (draft-ietf-emu-eap-gpsk-01.txt)
248 * added preliminary implementation of IEEE 802.11w/D1.0 (management
250 (Note: this requires driver support to work properly.)
251 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
252 * fixed Windows named pipes ctrl_iface to not stop listening for
253 commands if client program opens a named pipe and closes it
254 immediately without sending a command
255 * fixed USIM PIN status determination for the case that PIN is not
256 needed (this allows EAP-AKA to be used with USIM cards that do not
258 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
259 be used with cards that do not support file selection based on
261 * added support for matching the subjectAltName of the authentication
262 server certificate against multiple name components (e.g.,
263 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
264 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
265 affects IEEE 802.1X with dynamic WEP keys)
266 * changed ctrl_iface network configuration 'get' operations to not
267 return password/key material; if these fields are requested, "*"
268 will be returned if the password/key is set, but the value of the
269 parameter is not exposed
272 * added support for building Windows version with UNICODE defined
273 (wide-char functions)
274 * driver_ndis: fixed static WEP configuration to avoid race condition
275 issues with some NDIS drivers between association and setting WEP
277 * driver_ndis: added validation for IELength value in scan results to
278 avoid crashes when using buggy NDIS drivers [Bug 165]
279 * fixed Release|Win32 target in the Visual Studio project files
280 (previously, only Debug|Win32 target was set properly)
281 * changed control interface API call wpa_ctrl_pending() to allow it to
282 return -1 on error (e.g., connection lost); control interface clients
283 will need to make sure that they verify that the value is indeed >0
284 when determining whether there are pending messages
285 * added an alternative control interface backend for Windows targets:
286 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
287 control interface mechanism for Windows builds (previously, UDP to
289 * changed ctrl_interface configuration for UNIX domain sockets:
290 - deprecated ctrl_interface_group variable (it may be removed in
292 - allow both directory and group be configured with ctrl_interface
293 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
294 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
295 case when group is not changed
296 * added support for controlling more than one interface per process in
298 * added a workaround for a case where the AP is using unknown address
299 (e.g., MAC address of the wired interface) as the source address for
300 EAPOL-Key frames; previously, that source address was used as the
301 destination for EAPOL-Key frames and in key derivation; now, BSSID is
302 used even if the source address does not match with it
303 (this resolves an interoperability issue with Thomson SpeedTouch 580)
304 * added a workaround for UDP-based control interface (which was used in
305 Windows builds before this release) to prevent packets with forged
306 addresses from being accepted as local control requests
307 * removed ndis_events.cpp and possibility of using external
308 ndis_events.exe; C version (ndis_events.c) is fully functional and
309 there is no desire to maintain two separate versions of this
311 * ndis_events: Changed NDIS event notification design to use WMI to
312 learn the adapter description through Win32_PnPEntity class; this
313 should fix some cases where the adapter name was not recognized
314 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
316 * fixed selection of the first network in ap_scan=2 mode; previously,
317 wpa_supplicant could get stuck in SCANNING state when only the first
318 network for enabled (e.g., after 'wpa_cli select_network 0')
319 * winsvc: added support for configuring ctrl_interface parameters in
320 registry (ctrl_interface string value in
321 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
322 required to enable control interface (previously, this was hardcoded
324 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
325 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
328 * fixed build with CONFIG_STAKEY=y [Bug 143]
329 * added support for doing MLME (IEEE 802.11 management frame
330 processing) in wpa_supplicant when using Devicescape IEEE 802.11
331 stack (wireless-dev.git tree)
332 * added a new network block configuration option, fragment_size, to
333 configure the maximum EAP fragment size
334 * driver_ndis: Disable WZC automatically for the selected interface to
335 avoid conflicts with two programs trying to control the radio; WZC
336 will be re-enabled (if it was enabled originally) when wpa_supplicant
338 * added an experimental TLSv1 client implementation
339 (CONFIG_TLS=internal) that can be used instead of an external TLS
340 library, e.g., to reduce total size requirement on systems that do
341 not include any TLS library by default (this is not yet complete;
342 basic functionality is there, but certificate validation is not yet
344 * added PeerKey handshake implementation for IEEE 802.11e
345 direct link setup (DLS) to replace STAKey handshake
346 * fixed WPA PSK update through ctrl_iface for the case where the old
347 PSK was derived from an ASCII passphrase and the new PSK is set as
348 a raw PSK (hex string)
349 * added new configuration option for identifying which network block
350 was used (id_str in wpa_supplicant.conf; included on
351 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
352 variable in wpa_cli action scripts; in addition WPA_ID variable is
353 set to the current unique identifier that wpa_supplicant assigned
354 automatically for the network and that can be used with
355 GET_NETWORK/SET_NETWORK ctrl_iface commands)
356 * wpa_cli action script is now called only when the connect/disconnect
357 status changes or when associating with a different network
358 * fixed configuration parser not to remove CCMP from group cipher list
359 if WPA-None (adhoc) is used (pairwise=NONE in that case)
360 * fixed integrated NDIS events processing not to hang the process due
361 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
362 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
363 draft-clancy-emu-eap-shared-secret-00.txt)
364 * added Microsoft Visual Studio 2005 solution and project files for
365 build wpa_supplicant for Windows (see vs2005 subdirectory)
366 * eloop_win: fixed unregistration of Windows events
367 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
368 at the end of RSN pre-authentication and added unregistration of
369 a Windows event to avoid getting eloop_win stuck with an invalid
371 * driver_ndis: added support for selecting AP based on BSSID
372 * added new environmental variable for wpa_cli action scripts:
373 WPA_CTRL_DIR is the current control interface directory
374 * driver_ndis: added support for using NDISUIO instead of WinPcap for
375 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
376 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
377 wpa_supplicant without requiring WinPcap; note that using NDISUIO
378 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
379 only one application to open the device
380 * changed NDIS driver naming to only include device GUID, e.g.,
381 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
382 specific \Device\NPF_ prefix before the GUID; the prefix is still
383 allowed for backwards compatibility, but it is not required anymore
384 when specifying the interface
385 * driver_ndis: re-initialize driver interface is the adapter is removed
386 and re-inserted [Bug 159]
387 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
388 big endian hosts [Bug 146]
391 * fixed EAP-GTC response to include correct user identity when run as
392 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
393 * driver_ndis: Fixed encryption mode configuration for unencrypted
394 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
395 refused to associate with open networks) [Bug 106]
396 * driver_ndis: use BSSID OID polling to detect when IBSS network is
397 formed even when ndis_events code is included since some NDIS drivers
398 do not generate media connect events in IBSS mode
399 * config_winreg: allow global ctrl_interface parameter to be configured
401 * config_winreg: added support for saving configuration data into
403 * added support for controlling network device operational state
404 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
405 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
406 that can use this information)
407 * driver_wext: added support for WE-21 change to SSID configuration
408 * driver_wext: fixed privacy configuration for static WEP keys mode
410 * added an optional driver_ops callback for MLME-SETPROTECTION.request
412 * added support for EAP-SAKE (no EAP method number allocated yet, so
413 this is using the same experimental type 255 as EAP-PSK)
414 * added support for dynamically loading EAP methods (.so files) instead
415 of requiring them to be statically linked in; this is disabled by
416 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
420 * do not try to use USIM APDUs when initializing PC/SC for SIM card
421 access for a network that has not enabled EAP-AKA
422 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
423 v0.5.1 due to the new support for expanded EAP types)
424 * added support for generating EAP Expanded Nak
425 * try to fetch scan results once before requesting new scan when
426 starting up in ap_scan=1 mode (this can speed up initial association
427 a lot with, e.g., madwifi-ng driver)
428 * added support for receiving EAPOL frames from a Linux bridge
429 interface (-bbr0 on command line)
430 * fixed EAPOL re-authentication for sessions that used PMKSA caching
431 * changed EAP method registration to use a dynamic list of methods
432 instead of a static list generated at build time
433 * fixed PMKSA cache deinitialization not to use freed memory when
434 removing PMKSA entries
435 * fixed a memory leak in EAP-TTLS re-authentication
436 * reject WPA/WPA2 message 3/4 if it does not include any valid
438 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
439 if the driver does not support SIOCSIWAUTH
442 * driver_test: added better support for multiple APs and STAs by using
443 a directory with sockets that include MAC address for each device in
444 the name (driver_param=test_dir=/tmp/test)
445 * added support for EAP expanded type (vendor specific EAP methods)
446 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
447 option can be changed if needed
448 * wpa_cli/wpa_gui: skip non-socket files in control directory when
449 using UNIX domain sockets; this avoids selecting an incorrect
450 interface (e.g., a PID file could be in this directory, even though
451 use of this directory for something else than socket files is not
453 * fixed TLS library deinitialization after RSN pre-authentication not
454 to disable TLS library for normal authentication
455 * driver_wext: Remove null-termination from SSID length if the driver
456 used it; some Linux drivers do this and they were causing problems in
457 wpa_supplicant not finding matching configuration block. This change
458 would break a case where the SSID actually ends in '\0', but that is
459 not likely to happen in real use.
460 * fixed PMKSA cache processing not to trigger deauthentication if the
461 current PMKSA cache entry is replaced with a valid new entry
462 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
463 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
466 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
467 * added experimental STAKey handshake implementation for IEEE 802.11e
468 direct link setup (DLS); note: this is disabled by default in both
469 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
471 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
472 decrypt AT_ENCR_DATA attributes correctly
473 * fixed EAP-AKA to allow resynchronization within the same session
474 * made code closer to ANSI C89 standard to make it easier to port to
475 other C libraries and compilers
476 * started moving operating system or C library specific functions into
477 wrapper functions defined in os.h and implemented in os_*.c to make
479 * wpa_supplicant can now be built with Microsoft Visual C++
480 (e.g., with the freely available Toolkit 2003 version or Visual
481 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
482 example makefile for nmake
483 * added support for using Windows registry for command line parameters
484 (CONFIG_MAIN=main_winsvc) and configuration data
485 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
486 contents; this version can be run both as a Windows service and as a
487 normal application; 'wpasvc.exe app' to start as applicant,
488 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
489 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
491 * made it possible to link ndis_events.exe functionality into
492 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
493 * added better support for multiple control interface backends
494 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
495 * fixed PC/SC code to use correct length for GSM AUTH command buffer
496 and to not use pioRecvPci with SCardTransmit() calls; these were not
497 causing visible problems with pcsc-lite, but Windows Winscard.dll
498 refused the previously used parameters; this fixes EAP-SIM and
499 EAP-AKA authentication using SIM/USIM card under Windows
500 * added new event loop implementation for Windows using
501 WaitForMultipleObject() instead of select() in order to allow waiting
502 for non-socket objects; this can be selected with
503 CONFIG_ELOOP=eloop_win in .config
504 * added support for selecting l2_packet implementation in .config
505 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
506 winpcap, freebsd, none)
507 * added new l2_packet implementation for WinPcap
508 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
509 reduce latency in EAPOL receive processing from about 100 ms to about
511 * added support for EAP-FAST key derivation using other ciphers than
512 RC4-128-SHA for authentication and AES128-SHA for provisioning
513 * added support for configuring CA certificate as DER file and as a
515 * fixed private key configuration as configuration blob and added
516 support for using PKCS#12 as a blob
517 * tls_gnutls: added support for using PKCS#12 files; added support for
519 * added support for loading trusted CA certificates from Windows
520 certificate store: ca_cert="cert_store://<name>", where <name> is
521 likely CA (Intermediate CA certificates) or ROOT (root certificates)
522 * added C version of ndis_events.cpp and made it possible to build this
523 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
524 easily on cross-compilation builds
525 * added wpasvc.exe into Windows binary release; this is an alternative
526 version of wpa_supplicant.exe with configuration backend using
527 Windows registry and with the entry point designed to run as a
529 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
530 wpasvc.exe and removed this additional tool from the Windows binary
531 release since it is not needed anymore
532 * load winscard.dll functions dynamically when building with MinGW
533 since MinGW does not yet include winscard library
535 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
536 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
537 and WinPcap to receive frames sent to PAE group address
538 * disable EAP state machine when IEEE 802.1X authentication is not used
539 in order to get rid of bogus "EAP failed" messages
540 * fixed OpenSSL error reporting to go through all pending errors to
541 avoid confusing reports of old errors being reported at later point
543 * fixed configuration file updating to not write empty variables
544 (e.g., proto or key_mgmt) that the file parser would not accept
545 * fixed ADD_NETWORK ctrl_iface command to use the same default values
546 for variables as empty network definitions read from config file
548 * fixed EAP state machine to not discard EAP-Failure messages in many
549 cases (e.g., during TLS handshake)
550 * fixed a infinite loop in private key reading if the configured file
551 cannot be parsed successfully
552 * driver_madwifi: added support for madwifi-ng
553 * wpa_gui: do not display password/PSK field contents
554 * wpa_gui: added CA certificate configuration
555 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
556 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
557 the new AP is using different WPA/RSN IE
558 * use longer timeout for IEEE 802.11 association to avoid problems with
559 drivers that may take more than five second to associate
562 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
563 RSN IE, but WPA IE would match with wpa_supplicant configuration
564 * added support for named configuration blobs in order to avoid having
565 to use file system for external files (e.g., certificates);
566 variables can be set to "blob://<blob name>" instead of file path to
567 use a named blob; supported fields: pac_file, client_cert,
569 * fixed RSN pre-authentication (it was broken in the clean up of WPA
570 state machine interface in v0.4.5)
571 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
572 sure the driver configures broadcast decryption correctly
573 * added ca_path (and ca_path2) configuration variables that can be used
574 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
575 system-wide trusted CA list
576 * added support for starting wpa_supplicant without a configuration
577 file (-C argument must be used to set ctrl_interface parameter for
578 this case; in addition, -p argument can be used to provide
579 driver_param; these new arguments can also be used with a
580 configuration to override the values from the configuration)
581 * added global control interface that can be optionally used for adding
582 and removing network interfaces dynamically (-g command line argument
583 for both wpa_supplicant and wpa_cli) without having to restart
584 wpa_supplicant process
586 - try to save configuration whenever something is modified
587 - added WEP key configuration
588 - added possibility to edit the current network configuration
589 * driver_ndis: fixed driver polling not to increase frequency on each
590 received EAPOL frame due to incorrectly cancelled timeout
591 * added simple configuration file examples (in examples subdirectory)
592 * fixed driver_wext.c to filter wireless events based on ifindex to
593 avoid interfaces receiving events from other interfaces
594 * delay sending initial EAPOL-Start couple of seconds to speed up
595 authentication for the most common case of Authenticator starting
596 EAP authentication immediately after association
599 * added a workaround for clearing keys with ndiswrapper to allow
600 roaming from WPA enabled AP to plaintext one
601 * added docbook documentation (doc/docbook) that can be used to
602 generate, e.g., man pages
603 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
604 PF_PACKET in order to prepare for network devices that do not use
605 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
606 * use receipt of EAPOL-Key frame as a lower layer success indication
607 for EAP state machine to allow recovery from dropped EAP-Success
609 * cleaned up internal EAPOL frame processing by not including link
610 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
611 header is added only when transmitted the frame; this makes it easier
612 to use wpa_supplicant on link layers that use different header than
614 * updated EAP-PSK to use draft 9 by default since this can now be
615 tested with hostapd; removed support for draft 3, including
616 server_nai configuration option from network blocks
617 * driver_wired: add PAE address to the multicast address list in order
618 to be able to receive EAPOL frames with drivers that do not include
619 these multicast addresses by default
620 * driver_wext: add support for WE-19
621 * added support for multiple configuration backends (CONFIG_BACKEND
622 option); currently, only 'file' is supported (i.e., the format used
623 in wpa_supplicant.conf)
624 * added support for updating configuration ('wpa_cli save_config');
625 this is disabled by default and can be enabled with global
626 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
627 and wpa_gui to store the configuration changes in a permanent store
628 * added GET_NETWORK ctrl_iface command
629 (e.g., 'wpa_cli get_network 0 ssid')
632 * replaced OpenSSL patch for EAP-FAST support
633 (openssl-tls-extensions.patch) with a more generic and correct
634 patch (the new patch is not compatible with the previous one, so the
635 OpenSSL library will need to be patched with the new patch in order
636 to be able to build wpa_supplicant with EAP-FAST support)
637 * added support for using Windows certificate store (through CryptoAPI)
638 for client certificate and private key operations (EAP-TLS)
639 (see wpa_supplicant.conf for more information on how to configure
640 this with private_key)
641 * ported wpa_gui to Windows
642 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
643 built with the open source version of the Qt4 for Windows
644 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
645 with drivers that do not support WPA
646 * ndis_events: fixed Windows 2000 support
647 * added support for enabling/disabling networks from the list of all
648 configured networks ('wpa_cli enable_network <network id>' and
649 'wpa_cli disable_network <network id>')
650 * added support for adding and removing network from the current
651 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
652 <network id>'); added networks are disabled by default and they can
653 be enabled with enable_network command once the configuration is done
654 for the new network; note: configuration file is not yet updated, so
655 these new networks are lost when wpa_supplicant is restarted
656 * added support for setting network configuration parameters through
657 the control interface, for example:
658 wpa_cli set_network 0 ssid "\"my network\""
659 * fixed parsing of strings that include both " and # within double
660 quoted area (e.g., "start"#end")
661 * added EAP workaround for PEAP session resumption: allow outer,
662 i.e., not tunneled, EAP-Success to terminate session since; this can
663 be disabled with eap_workaround=0
664 (this was allowed for PEAPv1 before, but now it is also allowed for
665 PEAPv0 since at least one RADIUS authentication server seems to be
666 doing this for PEAPv0, too)
667 * wpa_gui: added preliminary support for adding new networks to the
668 wpa_supplicant configuration (double click on the scan results to
669 open network configuration)
672 * removed interface for external EAPOL/EAP supplicant (e.g.,
673 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
674 anymore and is unlikely to be used by anyone
675 * driver_ndis: fixed WinPcap 3.0 support
676 * fixed build with CONFIG_DNET_PCAP=y on Linux
677 * l2_packet: moved different implementations into separate files
681 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
682 (note: ipw2100-1.1.0 is likely to require an update to work with
684 * added support for using ap_scan=2 mode with multiple network blocks;
685 wpa_supplicant will go through the networks one by one until the
686 driver reports a successful association; this uses the same order for
687 networks as scan_ssid=1 scans, i.e., the priority field is ignored
688 and the network block order in the file is used instead
689 * fixed a potential issue in RSN pre-authentication ending up using
690 freed memory if pre-authentication times out
691 * added support for matching alternative subject name extensions of the
692 authentication server certificate; new configuration variables
693 altsubject_match and altsubject_match2
694 * driver_ndis: added support for IEEE 802.1X authentication with wired
696 * added support for querying private key password (EAP-TLS) through the
697 control interface (wpa_cli/wpa_gui) if one is not included in the
699 * driver_broadcom: fixed couple of memory leaks in scan result
701 * EAP-PAX is now registered as EAP type 46
702 * fixed EAP-PAX MAC calculation
703 * fixed EAP-PAX CK and ICK key derivation
704 * added support for using password with EAP-PAX (as an alternative to
705 entering key with eappsk); SHA-1 hash of the password will be used as
707 * added support for arbitrary driver interface parameters through the
708 configuration file with a new driver_param field; this adds a new
709 driver_ops function set_param()
710 * added possibility to override l2_packet module with driver interface
711 API (new send_eapol handler); this can be used to implement driver
712 specific TX/RX functions for EAPOL frames
713 * fixed ctrl_interface_group processing for the case where gid is
714 entered as a number, not group name
715 * driver_test: added support for testing hostapd with wpa_supplicant
716 by using test driver interface without any kernel drivers or network
720 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
721 packets to be encrypted; this was apparently broken by the changed
722 ioctl order in v0.4.0
723 * driver_madwifi: added preliminary support for compiling against 'BSD'
724 branch of madwifi CVS tree
725 * added support for EAP-MSCHAPv2 password retries within the same EAP
726 authentication session
727 * added support for password changes with EAP-MSCHAPv2 (used when the
728 password has expired)
729 * added support for reading additional certificates from PKCS#12 files
730 and adding them to the certificate chain
731 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
733 * fixed a possible double free in EAP-TTLS fast-reauthentication when
734 identity or password is entered through control interface
735 * display EAP Notification messages to user through control interface
736 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
737 * added GUI version of wpa_cli, wpa_gui; this is not build
738 automatically with 'make'; use 'make wpa_gui' to build (this requires
739 Qt development tools)
740 * added 'disconnect' command to control interface for setting
741 wpa_supplicant in state where it will not associate before
742 'reassociate' command has been used
743 * added support for selecting a network from the list of all configured
744 networks ('wpa_cli select_network <network id>'; this disabled all
745 other networks; to re-enable, 'wpa_cli select_network any')
746 * added support for getting scan results through control interface
747 * added EAP workaround for PEAPv1 session resumption: allow outer,
748 i.e., not tunneled, EAP-Success to terminate session since; this can
749 be disabled with eap_workaround=0
751 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
752 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
753 used to reduce the size of the wpa_supplicant considerably if
754 debugging code is not needed
755 * fixed EAPOL-Key validation to drop packets with invalid Key Data
756 Length; such frames could have crashed wpa_supplicant due to buffer
758 * added support for wired authentication (IEEE 802.1X on wired
759 Ethernet); driver interface 'wired'
760 * obsoleted set_wpa() handler in the driver interface API (it can be
761 replaced by moving enable/disable functionality into init()/deinit())
762 (calls to set_wpa() are still present for backwards compatibility,
763 but they may be removed in the future)
764 * driver_madwifi: fixed association in plaintext mode
765 * modified the EAP workaround that accepts EAP-Success with incorrect
766 Identifier to be even less strict about verification in order to
767 interoperate with some authentication servers
768 * added support for sending TLS alerts
769 * added support for 'any' SSID wildcard; if ssid is not configured or
770 is set to an empty string, any SSID will be accepted for non-WPA AP
771 * added support for asking PIN (for SIM) from frontends (e.g.,
772 wpa_cli); if a PIN is needed, but not included in the configuration
773 file, a control interface request is sent and EAP processing is
774 delayed until the PIN is available
775 * added support for using external devices (e.g., a smartcard) for
776 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
777 new wpa_supplicant.conf variables:
778 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
779 - network: engine, engine_id, key_id
780 * added experimental support for EAP-PAX
781 * added monitor mode for wpa_cli (-a<path to a program to run>) that
782 allows external commands (e.g., shell scripts) to be run based on
783 wpa_supplicant events, e.g., when authentication has been completed
784 and data connection is ready; other related wpa_cli arguments:
785 -B (run in background), -P (write PID file); wpa_supplicant has a new
786 command line argument (-W) that can be used to make it wait until a
787 control interface command is received in order to avoid missing
789 * added support for opportunistic WPA2 PMKSA key caching (disabled by
790 default, can be enabled with proactive_key_caching=1)
791 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
792 Authenticator rejects PMKSA caching attempt and the driver is not
793 using assoc_info events
794 * added -P<pid file> argument for wpa_supplicant to write the current
795 process id into a file
797 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
798 * added new phase1 option parameter, include_tls_length=1, to force
799 wpa_supplicant to add TLS Message Length field to all TLS messages
800 even if the packet is not fragmented; this may be needed with some
801 authentication servers
802 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
803 using drivers that take care of AP selection (e.g., when using
805 * fixed reprocessing of pending request after ctrl_iface requests for
806 identity/password/otp
807 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
808 EAP-PEAP and EAP-TTLS
809 * all drivers using driver_wext: set interface up and select Managed
810 mode when starting wpa_supplicant; set interface down when exiting
811 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
812 ipw2100 and ipw2200; please note that this also changed the
813 configuration variable in .config to CONFIG_DRIVER_IPW
816 * fixed a busy loop introduced in v0.3.5 for scan result processing
817 when no matching AP is found
820 * added a workaround for an interoperability issue with a Cisco AP
822 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
823 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
824 retransmission of dropped frames)
825 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
826 (e.g., segfault when processing EAPOL-Key frames)
827 * fixed EAP workaround and fast reauthentication configuration for
828 RSN pre-authentication; previously these were disabled and
829 pre-authentication would fail if the used authentication server
830 requires EAP workarounds
831 * added support for blacklisting APs that fail or timeout
832 authentication in ap_scan=1 mode so that all APs are tried in cases
833 where the ones with strongest signal level are failing authentication
834 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
835 authentication attempt
836 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
837 in the previous authentication (previously, only Phase 1 success was
841 * added preliminary support for IBSS (ad-hoc) mode configuration
842 (mode=1 in network block); this included a new key_mgmt mode
843 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
844 key management; see wpa_supplicant.conf for more details and an
845 example on how to configure this (note: this is currently implemented
846 only for driver_hostapd.c, but the changes should be trivial to add
847 in associate() handler for other drivers, too (assuming the driver
849 * added preliminary port for native Windows (i.e., no cygwin) using
853 * added optional support for GNU Readline and History Libraries for
854 wpa_cli (CONFIG_READLINE)
855 * cleaned up EAP state machine <-> method interface and number of
856 small problems with error case processing not terminating on
857 EAP-Failure but waiting for timeout
858 * added couple of workarounds for interoperability issues with a
859 Cisco AP when using WPA2
860 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
861 Note: This requires a patch for openssl to add support for TLS
862 extensions and number of workarounds for operations without
863 certificates. Proof of concept type of experimental patch is
864 included in openssl-tls-extensions.patch.
867 * fixed private key loading for cases where passphrase is not set
868 * fixed Windows/cygwin L2 packet handler freeing; previous version
869 could cause a segfault when RSN pre-authentication was completed
870 * added support for PMKSA caching with drivers that generate RSN IEs
871 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
872 but similar code can be easily added to driver_ndiswrapper.c once
873 ndiswrapper gets full support for RSN PMKSA caching
874 * improved recovery from PMKID mismatches by requesting full EAP
875 authentication in case of failed PMKSA caching attempt
876 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
877 (this requires that ndis_events is ran while wpa_supplicant is
879 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
880 * added support for driver interfaces to replace the interface name
881 based on driver/OS specific mapping, e.g., in case of driver_ndis,
882 this allows the beginning of the adapter description to be used as
884 * added support for CR+LF (Windows-style) line ends in configuration
886 * driver_ndis: enable radio before starting scanning, disable radio
888 * modified association event handler to set portEnabled = FALSE before
889 clearing port Valid in order to reset EAP state machine and avoid
890 problems with new authentication getting ignored because of state
891 machines ending up in AUTHENTICATED/SUCCESS state based on old
893 * added support for driver events to add PMKID candidates in order to
894 allow drivers to give priority to most likely roaming candidates
895 * driver_hostap: moved PrivacyInvoked configuration to associate()
896 function so that this will not be set for plaintext connections
897 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
898 interface can distinguish plaintext and IEEE 802.1X (no WPA)
900 * fixed static WEP key configuration to use broadcast/default type for
901 all keys (previously, the default TX key was configured as pairwise/
903 * driver_ndis: added legacy WPA capability detection for non-WPA2
905 * added support for setting static WEP keys for IEEE 802.1X without
906 dynamic WEP keying (eapol_flags=0)
909 * added support for reading PKCS#12 (PFX) files (as a replacement for
910 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
911 * fixed compilation with CONFIG_PCSC=y
912 * added new ap_scan mode, ap_scan=2, for drivers that take care of
913 association, but need to be configured with security policy and SSID,
914 e.g., ndiswrapper and NDIS driver; this mode should allow such
915 drivers to work with hidden SSIDs and optimized roaming; when
916 ap_scan=2 is used, only the first network block in the configuration
917 file is used and this configuration should have explicit security
918 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
919 group, proto variables
920 * added experimental port of wpa_supplicant for Windows
921 - driver_ndis.c driver interface (NDIS OIDs)
922 - currently, this requires cygwin and WinPcap
923 - small utility, win_if_list, can be used to get interface name
924 * control interface can now be removed at build time; add
925 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
926 * optional Xsupplicant interface can now be removed at build time;
927 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
928 * added auth_alg to driver interface associate() parameters to make it
929 easier for drivers to configure authentication algorithm as part of
932 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
933 * driver_broadcom: added new driver interface for Broadcom wl.o driver
934 (a generic driver for Broadcom IEEE 802.11a/g cards)
935 * wpa_cli: fixed parsing of -p <path> command line argument
936 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
937 ACK, not tunneled EAP-Success (of which only the first byte was
938 actually send due to a bug in previous code); this seems to
939 interoperate with most RADIUS servers that implements PEAPv1
940 * PEAPv1: added support for terminating PEAP authentication on tunneled
941 EAP-Success message; this can be configured by adding
942 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
943 (some RADIUS servers require this whereas others require a tunneled
945 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
946 the old label for key derivation; previously, the default was 1,
947 but it looks like most existing PEAPv1 implementations use the old
948 label which is thus more suitable default option
949 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
950 * fixed parsing of wep_tx_keyidx
951 * added support for configuring list of allowed Phase 2 EAP types
952 (for both EAP-PEAP and EAP-TTLS) instead of only one type
953 * added support for configuring IEEE 802.11 authentication algorithm
954 (auth_alg; mainly for using Shared Key authentication with static
956 * added support for EAP-AKA (with UMTS SIM)
957 * fixed couple of errors in PCSC handling that could have caused
958 random-looking errors for EAP-SIM
959 * added support for EAP-SIM pseudonyms and fast re-authentication
960 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
962 * added support for EAP-SIM with two challanges
963 (phase1="sim_min_num_chal=3" can be used to require three challenges)
964 * added support for configuring DH/DSA parameters for an ephemeral DH
965 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
966 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
967 and optional DH key exchange to achieve forward secracy with RSA keys
968 * added support for matching subject of the authentication server
969 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
970 configuration variables subject_match and subject_match2
971 * changed SSID configuration in driver_wext.c (used by many driver
972 interfaces) to use ssid_len+1 as the length for SSID since some Linux
974 * fixed couple of unaligned reads in scan result parsing to fix WPA
975 connection on some platforms (e.g., ARM)
976 * added driver interface for Intel ipw2100 driver
977 * added support for LEAP with WPA
978 * added support for larger scan results report (old limit was 4 kB of
979 data, i.e., about 35 or so APs) when using Linux wireless extensions
981 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
982 only if there is a PMKSA cache entry for the current AP
983 * fixed error handling for case where reading of scan results fails:
984 must schedule a new scan or wpa_supplicant will remain waiting
986 * changed debug output to remove shared password/key material by
987 default; all key information can be included with -K command line
988 argument to match the previous behavior
989 * added support for timestamping debug log messages (disabled by
990 default, can be enabled with -t command line argument)
991 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
992 if keys are not configured to be used; this fixes IEEE 802.1X mode
993 with drivers that use this information to configure whether Privacy
994 bit can be in Beacon frames (e.g., ndiswrapper)
995 * avoid clearing driver keys if no keys have been configured since last
996 key clear request; this seems to improve reliability of group key
997 handshake for ndiswrapper & NDIS driver which seems to be suffering
998 of some kind of timing issue when the keys are cleared again after
1000 * changed driver interface API:
1001 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
1002 version is being used (now, this is set to 2; previously, it was
1004 - pass pointer to private data structure to all calls
1005 - the new API is not backwards compatible; all in-tree driver
1006 interfaces has been converted to the new API
1007 * added support for controlling multiple interfaces (radios) per
1008 wpa_supplicant process; each interface needs to be listed on the
1009 command line (-c, -i, -D arguments) with -N as a separator
1010 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
1011 * added a workaround for EAP servers that incorrectly use same Id for
1012 sequential EAP packets
1013 * changed libpcap/libdnet configuration to use .config variable,
1014 CONFIG_DNET_PCAP, instead of requiring Makefile modification
1015 * improved downgrade attack detection in IE verification of msg 3/4:
1016 verify both WPA and RSN IEs, if present, not only the selected one;
1017 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
1018 Probe Response frame, and RSN is enabled in wpa_supplicant
1020 * fixed WPA msg 3/4 processing to allow Key Data field contain other
1021 IEs than just one WPA IE
1022 * added support for FreeBSD and driver interface for the BSD net80211
1023 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
1024 required kernel mods have not yet been committed
1025 * made EAP workarounds configurable; enabled by default, can be
1026 disabled with network block option eap_workaround=0
1028 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
1029 * resolved couple of interoperability issues with EAP-PEAPv1 and
1030 Phase 2 (inner EAP) fragment reassembly
1031 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
1032 AP is using non-zero key index for the unicast key and key index zero
1033 for the broadcast key
1034 * driver_hostap: fixed IEEE 802.1X WEP key updates and
1035 re-authentication by allowing unencrypted EAPOL frames when not using
1037 * added a new driver interface, 'wext', which uses only standard,
1038 driver independent functionality in Linux wireless extensions;
1039 currently, this can be used only for non-WPA IEEE 802.1X mode, but
1040 eventually, this is to be extended to support full WPA/WPA2 once
1041 Linux wireless extensions get support for this
1042 * added support for mode in which the driver is responsible for AP
1043 scanning and selection; this is disabled by default and can be
1044 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
1045 this mode can be used, e.g., with generic 'wext' driver interface to
1046 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
1047 supporting wireless extensions.
1048 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
1049 operation with an AP that does not include SSID in the Beacon frames)
1050 * added support for new EAP authentication methods:
1051 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
1052 * added support for asking one-time-passwords from frontends (e.g.,
1053 wpa_cli); this 'otp' command works otherwise like 'password' command,
1054 but the password is used only once and the frontend will be asked for
1055 a new password whenever a request from authenticator requires a
1056 password; this can be used with both EAP-OTP and EAP-GTC
1057 * changed wpa_cli to automatically re-establish connection so that it
1058 does not need to be re-started when wpa_supplicant is terminated and
1060 * improved user data (identity/password/otp) requests through
1061 frontends: process pending EAPOL packets after getting new
1062 information so that full authentication does not need to be
1063 restarted; in addition, send pending requests again whenever a new
1064 frontend is attached
1065 * changed control frontends to use a new directory for socket files to
1066 make it easier for wpa_cli to automatically select between interfaces
1067 and to provide access control for the control interface;
1068 wpa_supplicant.conf: ctrl_interface is now a path
1069 (/var/run/wpa_supplicant is the recommended path) and
1070 ctrl_interface_group can be used to select which group gets access to
1071 the control interface;
1072 wpa_cli: by default, try to connect to the first interface available
1073 in /var/run/wpa_supplicant; this path can be overriden with -p option
1074 and an interface can be selected with -i option (i.e., in most common
1075 cases, wpa_cli does not need to get any arguments)
1076 * added support for LEAP
1077 * added driver interface for Linux ndiswrapper
1078 * added priority option for network blocks in the configuration file;
1079 this allows networks to be grouped based on priority (the scan
1080 results are searched for matches with network blocks in this order)
1083 * sort scan results to improve AP selection
1084 * fixed control interface socket removal for some error cases
1085 * improved scan requesting and authentication timeout
1086 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1088 * PEAP version can now be forced with phase1="peapver=<ver>"
1089 (mostly for testing; by default, the highest version supported by
1090 both the Supplicant and Authentication Server is selected
1092 * added support for madwifi driver (Atheros ar521x)
1093 * added a workaround for cases where AP sets Install Tx/Rx bit for
1094 WPA Group Key messages when pairwise keys are used (without this,
1095 the Group Key would be used for Tx and the AP would drop frames
1097 * added GSM SIM/USIM interface for GSM authentication algorithm for
1098 EAP-SIM; this requires pcsc-lite
1099 * added support for ATMEL AT76C5XXx driver
1100 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1101 does not include key data in the EAPOL-Key frame (i.e., part of
1102 EAP keying material is used as data encryption key)
1103 * added support for using plaintext and static WEP networks
1107 * added support for new EAP authentication methods:
1108 EAP-TTLS/EAP-MD5-Challenge
1110 EAP-TTLS/EAP-MSCHAPv2
1118 EAP-PEAP/MD5-Challenge
1120 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1121 * added support for anonymous identity (to be used when identity is
1122 sent in plaintext; real identity will be used within TLS protected
1123 tunnel (e.g., with EAP-TTLS)
1124 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1125 * added support for requesting identity and password information using
1126 control interface; in other words, the password for EAP-PEAP or
1127 EAP-TTLS does not need to be included in the configuration file since
1128 a frontand (e.g., wpa_cli) can ask it from the user
1129 * improved RSN pre-authentication to use a candidate list and process
1130 all candidates from each scan; not only one per scan
1131 * fixed RSN IE and WPA IE capabilities field parsing
1132 * ignore Tx bit in GTK IE when Pairwise keys are used
1133 * avoid making new scan requests during IEEE 802.1X negotiation
1134 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1135 with TLS support (this replaces the included implementation with
1136 library code to save about 8 kB since the library code is needed
1138 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1139 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1142 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1144 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1145 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1146 - EAP-MD5 (cannot be used with WPA-RADIUS)
1147 [draft-ietf-eap-rfc2284bis-09.txt]
1148 - EAP-TLS [RFC 2716]
1149 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1150 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1151 [draft-kamath-pppext-eap-mschapv2-00.txt]
1152 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1153 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1154 - new configuration file options: eap, identity, password, ca_cert,
1155 client_cert, privatekey, private_key_passwd
1156 - Xsupplicant is not required anymore, but it can be used by
1157 disabling the internal IEEE 802.1X Supplicant with -e command line
1159 - this code is not included in the default build; Makefile need to
1160 be edited for this (uncomment lines for selected functionality)
1161 - EAP-TLS and EAP-PEAP require openssl libraries
1162 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1163 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1164 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1165 EAPOL-Key frames instead of WPA key handshakes)
1166 * added support for IEEE 802.11i/RSN (WPA2)
1167 - improved PTK Key Handshake
1168 - PMKSA caching, pre-authentication
1169 * fixed wpa_supplicant to ignore possible extra data after WPA
1170 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1171 TPTK' error from message 3 of 4-Way Handshake in case the AP
1172 includes extra data after the EAPOL-Key)
1173 * added interface for external programs (frontends) to control
1175 - CLI example (wpa_cli) with interactive mode and command line
1177 - replaced SIGUSR1 status/statistics with the new control interface
1178 * made some feature compile time configurable
1179 - .config file for make
1180 - driver interfaces (hostap, hermes, ..)
1181 - EAPOL/EAP functions
1184 * Initial version of wpa_supplicant
