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>)
8 * added support for Wi-Fi Protected Setup (WPS)
9 (wpa_supplicant can now be configured to act as a WPS Enrollee to
10 enroll credentials for a network using PIN and PBC methods; in
11 addition, wpa_supplicant can act as a wireless WPS Registrar to
12 configure an AP); WPS support can be enabled by adding CONFIG_WPS=y
13 into .config and setting the runtime configuration variables in
14 wpa_supplicant.conf (see WPS section in the example configuration
15 file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to
16 manage WPS negotiation; see README-WPS for more details
17 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
18 * added support for using driver_test over UDP socket
19 * fixed PEAPv0 Cryptobinding interoperability issue with Windows Server
20 2008 NPS; optional cryptobinding is now enabled (again) by default
21 * fixed PSK editing in wpa_gui
22 * changed EAP-GPSK to use the IANA assigned EAP method type 51
23 * added a Windows installer that includes WinPcap and all the needed
24 DLLs; in addition, it set up the registry automatically so that user
25 will only need start wpa_gui to get prompted to start the wpasvc
26 servide and add a new interface if needed through wpa_gui dialog
27 * updated management frame protection to use IEEE 802.11w/D7.0
30 * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
31 (can be used to simulate test SIM/USIM card with a known private key;
32 enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
33 and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
34 * added a new network configuration option, wpa_ptk_rekey, that can be
35 used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
36 against TKIP deficiencies
37 * added an optional mitigation mechanism for certain attacks against
38 TKIP by delaying Michael MIC error reports by a random amount of time
39 between 0 and 60 seconds; this can be enabled with a build option
40 CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
41 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
43 * updated OpenSSL code for EAP-FAST to use an updated version of the
44 session ticket overriding API that was included into the upstream
45 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
46 needed with that version anymore)
47 * updated userspace MLME instructions to match with the current Linux
48 mac80211 implementation; please also note that this can only be used
49 with driver_nl80211.c (the old code from driver_wext.c was removed)
50 * added support (Linux only) for RoboSwitch chipsets (often found in
51 consumer grade routers); driver interface 'roboswitch'
52 * fixed canceling of PMKSA caching when using drivers that generate
53 RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
57 * added support for SHA-256 as X.509 certificate digest when using the
58 internal X.509/TLSv1 implementation
59 * updated management frame protection to use IEEE 802.11w/D6.0
60 * added support for using SHA256-based stronger key derivation for WPA2
62 * fixed FT (IEEE 802.11r) authentication after a failed association to
64 * added support for configuring Phase 2 (inner/tunneled) authentication
65 method with wpa_gui-qt4
68 * added support for EAP Sequences in EAP-FAST Phase 2
69 * added support for using TNC with EAP-FAST
70 * added driver_ps3 for the PS3 Linux wireless driver
71 * added support for optional cryptobinding with PEAPv0
72 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
73 allow fallback to full handshake if server rejects PAC-Opaque
74 * added fragmentation support for EAP-TNC
75 * added support for parsing PKCS #8 formatted private keys into the
76 internal TLS implementation (both PKCS #1 RSA key and PKCS #8
77 encapsulated RSA key can now be used)
78 * added option of using faster, but larger, routines in the internal
79 LibTomMath (for internal TLS implementation) to speed up DH and RSA
80 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
81 * fixed race condition between disassociation event and group key
82 handshake to avoid getting stuck in incorrect state [Bug 261]
83 * fixed opportunistic key caching (proactive_key_caching)
86 * removed 'nai' and 'eappsk' network configuration variables that were
87 previously used for configuring user identity and key for EAP-PSK,
88 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
89 replacement for 'nai' (if old configuration used a separate
90 'identity' value, that would now be configured as
91 'anonymous_identity'). 'password' field is now used as the
92 replacement for 'eappsk' (it can also be set using hexstring to
93 present random binary data)
94 * removed '-w' command line parameter (wait for interface to be added,
95 if needed); cleaner way of handling this functionality is to use an
96 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
97 when an interface is added
98 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
99 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
100 indicating when new scan results become available
101 * added new ctrl_iface command, BSS, to allow scan results to be
102 fetched without hitting the message size limits (this command
103 can be used to iterate through the scan results one BSS at the time)
104 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
105 attributes in EAP-SIM Start/Response when using fast reauthentication
106 * fixed EAPOL not to end up in infinite loop when processing dynamic
107 WEP keys with IEEE 802.1X
108 * fixed problems in getting NDIS events from WMI on Windows 2000
111 * added support for Makefile builds to include debug-log-to-a-file
112 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
113 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
114 lengths properly to avoid potential crash caused by invalid messages
115 * added data structure for storing allocated buffers (struct wpabuf);
116 this does not affect wpa_supplicant usage, but many of the APIs
117 changed and various interfaces (e.g., EAP) is not compatible with old
119 * added support for protecting EAP-AKA/Identity messages with
120 AT_CHECKCODE (optional feature in RFC 4187)
121 * added support for protected result indication with AT_RESULT_IND for
122 EAP-SIM and EAP-AKA (phase1="result_ind=1")
123 * added driver_wext workaround for race condition between scanning and
124 association with drivers that take very long time to scan all
125 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
126 using a longer hardcoded timeout for the scan if the driver supports
127 notifications for scan completion (SIOCGIWSCAN event); this helps,
128 e.g., in cases where wpa_supplicant and madwifi driver ended up in
129 loop where the driver did not even try to associate
130 * stop EAPOL timer tick when no timers are in use in order to reduce
131 power consumption (no need to wake up the process once per second)
133 * added support for privilege separation (run only minimal part of
134 wpa_supplicant functionality as root and rest as unprivileged,
135 non-root process); see 'Privilege separation' in README for details;
136 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
138 * changed scan results data structure to include all information
139 elements to make it easier to support new IEs; old get_scan_result()
140 driver_ops is still supported for backwards compatibility (results
141 are converted internally to the new format), but all drivers should
142 start using the new get_scan_results2() to make them more likely to
143 work with new features
144 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
145 application, i.e., it does not require Qt3Support anymore; Windows
146 binary of wpa_gui.exe is now from this directory and only requires
147 QtCore4.dll and QtGui4.dll libraries
148 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
149 available as a separate package to make wpa_gui installation easier:
150 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
151 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
152 only shared key/password authentication is supported in this version
155 * added support for configuring password as NtPasswordHash
156 (16-byte MD4 hash of password) in hash:<32 hex digits> format
157 * added support for fallback from abbreviated TLS handshake to
158 full handshake when using EAP-FAST (e.g., due to an expired
160 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
161 draft (draft-ietf-emu-eap-gpsk-07.txt)
162 * added support for drivers that take care of RSN 4-way handshake
163 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
164 WPA_ALG_PMK in set_key)
165 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
166 .config); this version supports only ap_scan=2 mode and allow the
167 driver to take care of the 4-way handshake
168 * fixed a buffer overflow in parsing TSF from scan results when using
169 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
171 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
172 * fixed an integer overflow issue in the ASN.1 parser used by the
173 (experimental) internal TLS implementation to avoid a potential
175 * fixed a race condition with -W option (wait for a control interface
176 monitor before starting) that could have caused the first messages to
178 * added support for processing TNCC-TNCS-Messages to report
179 recommendation (allow/none/isolate) when using TNC [Bug 243]
182 * added network configuration parameter 'frequency' for setting
183 initial channel for IBSS (adhoc) networks
184 * added experimental IEEE 802.11r/D6.0 support
185 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
186 * updated EAP-PSK to use the IANA-allocated EAP type 47
187 * fixed EAP-PAX key derivation
188 * fixed EAP-PSK bit ordering of the Flags field
189 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
190 tunnelled identity request (previously, the identifier from the outer
191 method was used, not the tunnelled identifier which could be
193 * added support for fragmentation of outer TLS packets during Phase 2
194 of EAP-PEAP/TTLS/FAST
195 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
196 * added support for EAP-FAST authentication with inner methods that
197 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
198 for PAC provisioning)
199 * added support for authenticated EAP-FAST provisioning
200 * added support for configuring maximum number of EAP-FAST PACs to
201 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
202 * added support for storing EAP-FAST PACs in binary format
203 (fast_pac_format=binary in phase1 string)
204 * fixed dbus ctrl_iface to validate message interface before
205 dispatching to avoid a possible segfault [Bug 190]
206 * fixed PeerKey key derivation to use the correct PRF label
207 * updated Windows binary build to link against OpenSSL 0.9.8d and
208 added support for EAP-FAST
209 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
210 draft (draft-ietf-emu-eap-gpsk-04.txt)
211 * fixed EAP-AKA Notification processing to allow Notification to be
212 processed after AKA Challenge response has been sent
213 * updated to use IEEE 802.11w/D2.0 for management frame protection
215 * fixed EAP-TTLS implementation not to crash on use of freed memory
216 if TLS library initialization fails
217 * added support for EAP-TNC (Trusted Network Connect)
218 (this version implements the EAP-TNC method and EAP-TTLS changes
219 needed to run two methods in sequence (IF-T) and the IF-IMC and
220 IF-TNCCS interfaces from TNCC)
223 * added experimental, integrated TLSv1 client implementation with the
224 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
225 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
226 .config); this can be useful, e.g., if the target system does not
227 have a suitable TLS library and a minimal code size is required
228 (total size of this internal TLS/crypto code is bit under 50 kB on
229 x86 and the crypto code is shared by rest of the supplicant so some
230 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
231 * removed STAKey handshake since PeerKey handshake has replaced it in
232 IEEE 802.11ma and there are no known deployments of STAKey
233 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
234 draft (draft-ietf-emu-eap-gpsk-01.txt)
235 * added preliminary implementation of IEEE 802.11w/D1.0 (management
237 (Note: this requires driver support to work properly.)
238 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
239 * fixed Windows named pipes ctrl_iface to not stop listening for
240 commands if client program opens a named pipe and closes it
241 immediately without sending a command
242 * fixed USIM PIN status determination for the case that PIN is not
243 needed (this allows EAP-AKA to be used with USIM cards that do not
245 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
246 be used with cards that do not support file selection based on
248 * added support for matching the subjectAltName of the authentication
249 server certificate against multiple name components (e.g.,
250 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
251 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
252 affects IEEE 802.1X with dynamic WEP keys)
253 * changed ctrl_iface network configuration 'get' operations to not
254 return password/key material; if these fields are requested, "*"
255 will be returned if the password/key is set, but the value of the
256 parameter is not exposed
259 * added support for building Windows version with UNICODE defined
260 (wide-char functions)
261 * driver_ndis: fixed static WEP configuration to avoid race condition
262 issues with some NDIS drivers between association and setting WEP
264 * driver_ndis: added validation for IELength value in scan results to
265 avoid crashes when using buggy NDIS drivers [Bug 165]
266 * fixed Release|Win32 target in the Visual Studio project files
267 (previously, only Debug|Win32 target was set properly)
268 * changed control interface API call wpa_ctrl_pending() to allow it to
269 return -1 on error (e.g., connection lost); control interface clients
270 will need to make sure that they verify that the value is indeed >0
271 when determining whether there are pending messages
272 * added an alternative control interface backend for Windows targets:
273 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
274 control interface mechanism for Windows builds (previously, UDP to
276 * changed ctrl_interface configuration for UNIX domain sockets:
277 - deprecated ctrl_interface_group variable (it may be removed in
279 - allow both directory and group be configured with ctrl_interface
280 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
281 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
282 case when group is not changed
283 * added support for controlling more than one interface per process in
285 * added a workaround for a case where the AP is using unknown address
286 (e.g., MAC address of the wired interface) as the source address for
287 EAPOL-Key frames; previously, that source address was used as the
288 destination for EAPOL-Key frames and in key derivation; now, BSSID is
289 used even if the source address does not match with it
290 (this resolves an interoperability issue with Thomson SpeedTouch 580)
291 * added a workaround for UDP-based control interface (which was used in
292 Windows builds before this release) to prevent packets with forged
293 addresses from being accepted as local control requests
294 * removed ndis_events.cpp and possibility of using external
295 ndis_events.exe; C version (ndis_events.c) is fully functional and
296 there is no desire to maintain two separate versions of this
298 * ndis_events: Changed NDIS event notification design to use WMI to
299 learn the adapter description through Win32_PnPEntity class; this
300 should fix some cases where the adapter name was not recognized
301 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
303 * fixed selection of the first network in ap_scan=2 mode; previously,
304 wpa_supplicant could get stuck in SCANNING state when only the first
305 network for enabled (e.g., after 'wpa_cli select_network 0')
306 * winsvc: added support for configuring ctrl_interface parameters in
307 registry (ctrl_interface string value in
308 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
309 required to enable control interface (previously, this was hardcoded
311 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
312 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
315 * fixed build with CONFIG_STAKEY=y [Bug 143]
316 * added support for doing MLME (IEEE 802.11 management frame
317 processing) in wpa_supplicant when using Devicescape IEEE 802.11
318 stack (wireless-dev.git tree)
319 * added a new network block configuration option, fragment_size, to
320 configure the maximum EAP fragment size
321 * driver_ndis: Disable WZC automatically for the selected interface to
322 avoid conflicts with two programs trying to control the radio; WZC
323 will be re-enabled (if it was enabled originally) when wpa_supplicant
325 * added an experimental TLSv1 client implementation
326 (CONFIG_TLS=internal) that can be used instead of an external TLS
327 library, e.g., to reduce total size requirement on systems that do
328 not include any TLS library by default (this is not yet complete;
329 basic functionality is there, but certificate validation is not yet
331 * added PeerKey handshake implementation for IEEE 802.11e
332 direct link setup (DLS) to replace STAKey handshake
333 * fixed WPA PSK update through ctrl_iface for the case where the old
334 PSK was derived from an ASCII passphrase and the new PSK is set as
335 a raw PSK (hex string)
336 * added new configuration option for identifying which network block
337 was used (id_str in wpa_supplicant.conf; included on
338 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
339 variable in wpa_cli action scripts; in addition WPA_ID variable is
340 set to the current unique identifier that wpa_supplicant assigned
341 automatically for the network and that can be used with
342 GET_NETWORK/SET_NETWORK ctrl_iface commands)
343 * wpa_cli action script is now called only when the connect/disconnect
344 status changes or when associating with a different network
345 * fixed configuration parser not to remove CCMP from group cipher list
346 if WPA-None (adhoc) is used (pairwise=NONE in that case)
347 * fixed integrated NDIS events processing not to hang the process due
348 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
349 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
350 draft-clancy-emu-eap-shared-secret-00.txt)
351 * added Microsoft Visual Studio 2005 solution and project files for
352 build wpa_supplicant for Windows (see vs2005 subdirectory)
353 * eloop_win: fixed unregistration of Windows events
354 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
355 at the end of RSN pre-authentication and added unregistration of
356 a Windows event to avoid getting eloop_win stuck with an invalid
358 * driver_ndis: added support for selecting AP based on BSSID
359 * added new environmental variable for wpa_cli action scripts:
360 WPA_CTRL_DIR is the current control interface directory
361 * driver_ndis: added support for using NDISUIO instead of WinPcap for
362 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
363 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
364 wpa_supplicant without requiring WinPcap; note that using NDISUIO
365 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
366 only one application to open the device
367 * changed NDIS driver naming to only include device GUID, e.g.,
368 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
369 specific \Device\NPF_ prefix before the GUID; the prefix is still
370 allowed for backwards compatibility, but it is not required anymore
371 when specifying the interface
372 * driver_ndis: re-initialize driver interface is the adapter is removed
373 and re-inserted [Bug 159]
374 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
375 big endian hosts [Bug 146]
378 * fixed EAP-GTC response to include correct user identity when run as
379 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
380 * driver_ndis: Fixed encryption mode configuration for unencrypted
381 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
382 refused to associate with open networks) [Bug 106]
383 * driver_ndis: use BSSID OID polling to detect when IBSS network is
384 formed even when ndis_events code is included since some NDIS drivers
385 do not generate media connect events in IBSS mode
386 * config_winreg: allow global ctrl_interface parameter to be configured
388 * config_winreg: added support for saving configuration data into
390 * added support for controlling network device operational state
391 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
392 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
393 that can use this information)
394 * driver_wext: added support for WE-21 change to SSID configuration
395 * driver_wext: fixed privacy configuration for static WEP keys mode
397 * added an optional driver_ops callback for MLME-SETPROTECTION.request
399 * added support for EAP-SAKE (no EAP method number allocated yet, so
400 this is using the same experimental type 255 as EAP-PSK)
401 * added support for dynamically loading EAP methods (.so files) instead
402 of requiring them to be statically linked in; this is disabled by
403 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
407 * do not try to use USIM APDUs when initializing PC/SC for SIM card
408 access for a network that has not enabled EAP-AKA
409 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
410 v0.5.1 due to the new support for expanded EAP types)
411 * added support for generating EAP Expanded Nak
412 * try to fetch scan results once before requesting new scan when
413 starting up in ap_scan=1 mode (this can speed up initial association
414 a lot with, e.g., madwifi-ng driver)
415 * added support for receiving EAPOL frames from a Linux bridge
416 interface (-bbr0 on command line)
417 * fixed EAPOL re-authentication for sessions that used PMKSA caching
418 * changed EAP method registration to use a dynamic list of methods
419 instead of a static list generated at build time
420 * fixed PMKSA cache deinitialization not to use freed memory when
421 removing PMKSA entries
422 * fixed a memory leak in EAP-TTLS re-authentication
423 * reject WPA/WPA2 message 3/4 if it does not include any valid
425 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
426 if the driver does not support SIOCSIWAUTH
429 * driver_test: added better support for multiple APs and STAs by using
430 a directory with sockets that include MAC address for each device in
431 the name (driver_param=test_dir=/tmp/test)
432 * added support for EAP expanded type (vendor specific EAP methods)
433 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
434 option can be changed if needed
435 * wpa_cli/wpa_gui: skip non-socket files in control directory when
436 using UNIX domain sockets; this avoids selecting an incorrect
437 interface (e.g., a PID file could be in this directory, even though
438 use of this directory for something else than socket files is not
440 * fixed TLS library deinitialization after RSN pre-authentication not
441 to disable TLS library for normal authentication
442 * driver_wext: Remove null-termination from SSID length if the driver
443 used it; some Linux drivers do this and they were causing problems in
444 wpa_supplicant not finding matching configuration block. This change
445 would break a case where the SSID actually ends in '\0', but that is
446 not likely to happen in real use.
447 * fixed PMKSA cache processing not to trigger deauthentication if the
448 current PMKSA cache entry is replaced with a valid new entry
449 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
450 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
453 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
454 * added experimental STAKey handshake implementation for IEEE 802.11e
455 direct link setup (DLS); note: this is disabled by default in both
456 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
458 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
459 decrypt AT_ENCR_DATA attributes correctly
460 * fixed EAP-AKA to allow resynchronization within the same session
461 * made code closer to ANSI C89 standard to make it easier to port to
462 other C libraries and compilers
463 * started moving operating system or C library specific functions into
464 wrapper functions defined in os.h and implemented in os_*.c to make
466 * wpa_supplicant can now be built with Microsoft Visual C++
467 (e.g., with the freely available Toolkit 2003 version or Visual
468 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
469 example makefile for nmake
470 * added support for using Windows registry for command line parameters
471 (CONFIG_MAIN=main_winsvc) and configuration data
472 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
473 contents; this version can be run both as a Windows service and as a
474 normal application; 'wpasvc.exe app' to start as applicant,
475 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
476 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
478 * made it possible to link ndis_events.exe functionality into
479 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
480 * added better support for multiple control interface backends
481 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
482 * fixed PC/SC code to use correct length for GSM AUTH command buffer
483 and to not use pioRecvPci with SCardTransmit() calls; these were not
484 causing visible problems with pcsc-lite, but Windows Winscard.dll
485 refused the previously used parameters; this fixes EAP-SIM and
486 EAP-AKA authentication using SIM/USIM card under Windows
487 * added new event loop implementation for Windows using
488 WaitForMultipleObject() instead of select() in order to allow waiting
489 for non-socket objects; this can be selected with
490 CONFIG_ELOOP=eloop_win in .config
491 * added support for selecting l2_packet implementation in .config
492 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
493 winpcap, freebsd, none)
494 * added new l2_packet implementation for WinPcap
495 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
496 reduce latency in EAPOL receive processing from about 100 ms to about
498 * added support for EAP-FAST key derivation using other ciphers than
499 RC4-128-SHA for authentication and AES128-SHA for provisioning
500 * added support for configuring CA certificate as DER file and as a
502 * fixed private key configuration as configuration blob and added
503 support for using PKCS#12 as a blob
504 * tls_gnutls: added support for using PKCS#12 files; added support for
506 * added support for loading trusted CA certificates from Windows
507 certificate store: ca_cert="cert_store://<name>", where <name> is
508 likely CA (Intermediate CA certificates) or ROOT (root certificates)
509 * added C version of ndis_events.cpp and made it possible to build this
510 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
511 easily on cross-compilation builds
512 * added wpasvc.exe into Windows binary release; this is an alternative
513 version of wpa_supplicant.exe with configuration backend using
514 Windows registry and with the entry point designed to run as a
516 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
517 wpasvc.exe and removed this additional tool from the Windows binary
518 release since it is not needed anymore
519 * load winscard.dll functions dynamically when building with MinGW
520 since MinGW does not yet include winscard library
522 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
523 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
524 and WinPcap to receive frames sent to PAE group address
525 * disable EAP state machine when IEEE 802.1X authentication is not used
526 in order to get rid of bogus "EAP failed" messages
527 * fixed OpenSSL error reporting to go through all pending errors to
528 avoid confusing reports of old errors being reported at later point
530 * fixed configuration file updating to not write empty variables
531 (e.g., proto or key_mgmt) that the file parser would not accept
532 * fixed ADD_NETWORK ctrl_iface command to use the same default values
533 for variables as empty network definitions read from config file
535 * fixed EAP state machine to not discard EAP-Failure messages in many
536 cases (e.g., during TLS handshake)
537 * fixed a infinite loop in private key reading if the configured file
538 cannot be parsed successfully
539 * driver_madwifi: added support for madwifi-ng
540 * wpa_gui: do not display password/PSK field contents
541 * wpa_gui: added CA certificate configuration
542 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
543 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
544 the new AP is using different WPA/RSN IE
545 * use longer timeout for IEEE 802.11 association to avoid problems with
546 drivers that may take more than five second to associate
549 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
550 RSN IE, but WPA IE would match with wpa_supplicant configuration
551 * added support for named configuration blobs in order to avoid having
552 to use file system for external files (e.g., certificates);
553 variables can be set to "blob://<blob name>" instead of file path to
554 use a named blob; supported fields: pac_file, client_cert,
556 * fixed RSN pre-authentication (it was broken in the clean up of WPA
557 state machine interface in v0.4.5)
558 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
559 sure the driver configures broadcast decryption correctly
560 * added ca_path (and ca_path2) configuration variables that can be used
561 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
562 system-wide trusted CA list
563 * added support for starting wpa_supplicant without a configuration
564 file (-C argument must be used to set ctrl_interface parameter for
565 this case; in addition, -p argument can be used to provide
566 driver_param; these new arguments can also be used with a
567 configuration to override the values from the configuration)
568 * added global control interface that can be optionally used for adding
569 and removing network interfaces dynamically (-g command line argument
570 for both wpa_supplicant and wpa_cli) without having to restart
571 wpa_supplicant process
573 - try to save configuration whenever something is modified
574 - added WEP key configuration
575 - added possibility to edit the current network configuration
576 * driver_ndis: fixed driver polling not to increase frequency on each
577 received EAPOL frame due to incorrectly cancelled timeout
578 * added simple configuration file examples (in examples subdirectory)
579 * fixed driver_wext.c to filter wireless events based on ifindex to
580 avoid interfaces receiving events from other interfaces
581 * delay sending initial EAPOL-Start couple of seconds to speed up
582 authentication for the most common case of Authenticator starting
583 EAP authentication immediately after association
586 * added a workaround for clearing keys with ndiswrapper to allow
587 roaming from WPA enabled AP to plaintext one
588 * added docbook documentation (doc/docbook) that can be used to
589 generate, e.g., man pages
590 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
591 PF_PACKET in order to prepare for network devices that do not use
592 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
593 * use receipt of EAPOL-Key frame as a lower layer success indication
594 for EAP state machine to allow recovery from dropped EAP-Success
596 * cleaned up internal EAPOL frame processing by not including link
597 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
598 header is added only when transmitted the frame; this makes it easier
599 to use wpa_supplicant on link layers that use different header than
601 * updated EAP-PSK to use draft 9 by default since this can now be
602 tested with hostapd; removed support for draft 3, including
603 server_nai configuration option from network blocks
604 * driver_wired: add PAE address to the multicast address list in order
605 to be able to receive EAPOL frames with drivers that do not include
606 these multicast addresses by default
607 * driver_wext: add support for WE-19
608 * added support for multiple configuration backends (CONFIG_BACKEND
609 option); currently, only 'file' is supported (i.e., the format used
610 in wpa_supplicant.conf)
611 * added support for updating configuration ('wpa_cli save_config');
612 this is disabled by default and can be enabled with global
613 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
614 and wpa_gui to store the configuration changes in a permanent store
615 * added GET_NETWORK ctrl_iface command
616 (e.g., 'wpa_cli get_network 0 ssid')
619 * replaced OpenSSL patch for EAP-FAST support
620 (openssl-tls-extensions.patch) with a more generic and correct
621 patch (the new patch is not compatible with the previous one, so the
622 OpenSSL library will need to be patched with the new patch in order
623 to be able to build wpa_supplicant with EAP-FAST support)
624 * added support for using Windows certificate store (through CryptoAPI)
625 for client certificate and private key operations (EAP-TLS)
626 (see wpa_supplicant.conf for more information on how to configure
627 this with private_key)
628 * ported wpa_gui to Windows
629 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
630 built with the open source version of the Qt4 for Windows
631 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
632 with drivers that do not support WPA
633 * ndis_events: fixed Windows 2000 support
634 * added support for enabling/disabling networks from the list of all
635 configured networks ('wpa_cli enable_network <network id>' and
636 'wpa_cli disable_network <network id>')
637 * added support for adding and removing network from the current
638 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
639 <network id>'); added networks are disabled by default and they can
640 be enabled with enable_network command once the configuration is done
641 for the new network; note: configuration file is not yet updated, so
642 these new networks are lost when wpa_supplicant is restarted
643 * added support for setting network configuration parameters through
644 the control interface, for example:
645 wpa_cli set_network 0 ssid "\"my network\""
646 * fixed parsing of strings that include both " and # within double
647 quoted area (e.g., "start"#end")
648 * added EAP workaround for PEAP session resumption: allow outer,
649 i.e., not tunneled, EAP-Success to terminate session since; this can
650 be disabled with eap_workaround=0
651 (this was allowed for PEAPv1 before, but now it is also allowed for
652 PEAPv0 since at least one RADIUS authentication server seems to be
653 doing this for PEAPv0, too)
654 * wpa_gui: added preliminary support for adding new networks to the
655 wpa_supplicant configuration (double click on the scan results to
656 open network configuration)
659 * removed interface for external EAPOL/EAP supplicant (e.g.,
660 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
661 anymore and is unlikely to be used by anyone
662 * driver_ndis: fixed WinPcap 3.0 support
663 * fixed build with CONFIG_DNET_PCAP=y on Linux
664 * l2_packet: moved different implementations into separate files
668 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
669 (note: ipw2100-1.1.0 is likely to require an update to work with
671 * added support for using ap_scan=2 mode with multiple network blocks;
672 wpa_supplicant will go through the networks one by one until the
673 driver reports a successful association; this uses the same order for
674 networks as scan_ssid=1 scans, i.e., the priority field is ignored
675 and the network block order in the file is used instead
676 * fixed a potential issue in RSN pre-authentication ending up using
677 freed memory if pre-authentication times out
678 * added support for matching alternative subject name extensions of the
679 authentication server certificate; new configuration variables
680 altsubject_match and altsubject_match2
681 * driver_ndis: added support for IEEE 802.1X authentication with wired
683 * added support for querying private key password (EAP-TLS) through the
684 control interface (wpa_cli/wpa_gui) if one is not included in the
686 * driver_broadcom: fixed couple of memory leaks in scan result
688 * EAP-PAX is now registered as EAP type 46
689 * fixed EAP-PAX MAC calculation
690 * fixed EAP-PAX CK and ICK key derivation
691 * added support for using password with EAP-PAX (as an alternative to
692 entering key with eappsk); SHA-1 hash of the password will be used as
694 * added support for arbitrary driver interface parameters through the
695 configuration file with a new driver_param field; this adds a new
696 driver_ops function set_param()
697 * added possibility to override l2_packet module with driver interface
698 API (new send_eapol handler); this can be used to implement driver
699 specific TX/RX functions for EAPOL frames
700 * fixed ctrl_interface_group processing for the case where gid is
701 entered as a number, not group name
702 * driver_test: added support for testing hostapd with wpa_supplicant
703 by using test driver interface without any kernel drivers or network
707 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
708 packets to be encrypted; this was apparently broken by the changed
709 ioctl order in v0.4.0
710 * driver_madwifi: added preliminary support for compiling against 'BSD'
711 branch of madwifi CVS tree
712 * added support for EAP-MSCHAPv2 password retries within the same EAP
713 authentication session
714 * added support for password changes with EAP-MSCHAPv2 (used when the
715 password has expired)
716 * added support for reading additional certificates from PKCS#12 files
717 and adding them to the certificate chain
718 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
720 * fixed a possible double free in EAP-TTLS fast-reauthentication when
721 identity or password is entered through control interface
722 * display EAP Notification messages to user through control interface
723 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
724 * added GUI version of wpa_cli, wpa_gui; this is not build
725 automatically with 'make'; use 'make wpa_gui' to build (this requires
726 Qt development tools)
727 * added 'disconnect' command to control interface for setting
728 wpa_supplicant in state where it will not associate before
729 'reassociate' command has been used
730 * added support for selecting a network from the list of all configured
731 networks ('wpa_cli select_network <network id>'; this disabled all
732 other networks; to re-enable, 'wpa_cli select_network any')
733 * added support for getting scan results through control interface
734 * added EAP workaround for PEAPv1 session resumption: allow outer,
735 i.e., not tunneled, EAP-Success to terminate session since; this can
736 be disabled with eap_workaround=0
738 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
739 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
740 used to reduce the size of the wpa_supplicant considerably if
741 debugging code is not needed
742 * fixed EAPOL-Key validation to drop packets with invalid Key Data
743 Length; such frames could have crashed wpa_supplicant due to buffer
745 * added support for wired authentication (IEEE 802.1X on wired
746 Ethernet); driver interface 'wired'
747 * obsoleted set_wpa() handler in the driver interface API (it can be
748 replaced by moving enable/disable functionality into init()/deinit())
749 (calls to set_wpa() are still present for backwards compatibility,
750 but they may be removed in the future)
751 * driver_madwifi: fixed association in plaintext mode
752 * modified the EAP workaround that accepts EAP-Success with incorrect
753 Identifier to be even less strict about verification in order to
754 interoperate with some authentication servers
755 * added support for sending TLS alerts
756 * added support for 'any' SSID wildcard; if ssid is not configured or
757 is set to an empty string, any SSID will be accepted for non-WPA AP
758 * added support for asking PIN (for SIM) from frontends (e.g.,
759 wpa_cli); if a PIN is needed, but not included in the configuration
760 file, a control interface request is sent and EAP processing is
761 delayed until the PIN is available
762 * added support for using external devices (e.g., a smartcard) for
763 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
764 new wpa_supplicant.conf variables:
765 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
766 - network: engine, engine_id, key_id
767 * added experimental support for EAP-PAX
768 * added monitor mode for wpa_cli (-a<path to a program to run>) that
769 allows external commands (e.g., shell scripts) to be run based on
770 wpa_supplicant events, e.g., when authentication has been completed
771 and data connection is ready; other related wpa_cli arguments:
772 -B (run in background), -P (write PID file); wpa_supplicant has a new
773 command line argument (-W) that can be used to make it wait until a
774 control interface command is received in order to avoid missing
776 * added support for opportunistic WPA2 PMKSA key caching (disabled by
777 default, can be enabled with proactive_key_caching=1)
778 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
779 Authenticator rejects PMKSA caching attempt and the driver is not
780 using assoc_info events
781 * added -P<pid file> argument for wpa_supplicant to write the current
782 process id into a file
784 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
785 * added new phase1 option parameter, include_tls_length=1, to force
786 wpa_supplicant to add TLS Message Length field to all TLS messages
787 even if the packet is not fragmented; this may be needed with some
788 authentication servers
789 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
790 using drivers that take care of AP selection (e.g., when using
792 * fixed reprocessing of pending request after ctrl_iface requests for
793 identity/password/otp
794 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
795 EAP-PEAP and EAP-TTLS
796 * all drivers using driver_wext: set interface up and select Managed
797 mode when starting wpa_supplicant; set interface down when exiting
798 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
799 ipw2100 and ipw2200; please note that this also changed the
800 configuration variable in .config to CONFIG_DRIVER_IPW
803 * fixed a busy loop introduced in v0.3.5 for scan result processing
804 when no matching AP is found
807 * added a workaround for an interoperability issue with a Cisco AP
809 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
810 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
811 retransmission of dropped frames)
812 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
813 (e.g., segfault when processing EAPOL-Key frames)
814 * fixed EAP workaround and fast reauthentication configuration for
815 RSN pre-authentication; previously these were disabled and
816 pre-authentication would fail if the used authentication server
817 requires EAP workarounds
818 * added support for blacklisting APs that fail or timeout
819 authentication in ap_scan=1 mode so that all APs are tried in cases
820 where the ones with strongest signal level are failing authentication
821 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
822 authentication attempt
823 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
824 in the previous authentication (previously, only Phase 1 success was
828 * added preliminary support for IBSS (ad-hoc) mode configuration
829 (mode=1 in network block); this included a new key_mgmt mode
830 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
831 key management; see wpa_supplicant.conf for more details and an
832 example on how to configure this (note: this is currently implemented
833 only for driver_hostapd.c, but the changes should be trivial to add
834 in associate() handler for other drivers, too (assuming the driver
836 * added preliminary port for native Windows (i.e., no cygwin) using
840 * added optional support for GNU Readline and History Libraries for
841 wpa_cli (CONFIG_READLINE)
842 * cleaned up EAP state machine <-> method interface and number of
843 small problems with error case processing not terminating on
844 EAP-Failure but waiting for timeout
845 * added couple of workarounds for interoperability issues with a
846 Cisco AP when using WPA2
847 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
848 Note: This requires a patch for openssl to add support for TLS
849 extensions and number of workarounds for operations without
850 certificates. Proof of concept type of experimental patch is
851 included in openssl-tls-extensions.patch.
854 * fixed private key loading for cases where passphrase is not set
855 * fixed Windows/cygwin L2 packet handler freeing; previous version
856 could cause a segfault when RSN pre-authentication was completed
857 * added support for PMKSA caching with drivers that generate RSN IEs
858 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
859 but similar code can be easily added to driver_ndiswrapper.c once
860 ndiswrapper gets full support for RSN PMKSA caching
861 * improved recovery from PMKID mismatches by requesting full EAP
862 authentication in case of failed PMKSA caching attempt
863 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
864 (this requires that ndis_events is ran while wpa_supplicant is
866 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
867 * added support for driver interfaces to replace the interface name
868 based on driver/OS specific mapping, e.g., in case of driver_ndis,
869 this allows the beginning of the adapter description to be used as
871 * added support for CR+LF (Windows-style) line ends in configuration
873 * driver_ndis: enable radio before starting scanning, disable radio
875 * modified association event handler to set portEnabled = FALSE before
876 clearing port Valid in order to reset EAP state machine and avoid
877 problems with new authentication getting ignored because of state
878 machines ending up in AUTHENTICATED/SUCCESS state based on old
880 * added support for driver events to add PMKID candidates in order to
881 allow drivers to give priority to most likely roaming candidates
882 * driver_hostap: moved PrivacyInvoked configuration to associate()
883 function so that this will not be set for plaintext connections
884 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
885 interface can distinguish plaintext and IEEE 802.1X (no WPA)
887 * fixed static WEP key configuration to use broadcast/default type for
888 all keys (previously, the default TX key was configured as pairwise/
890 * driver_ndis: added legacy WPA capability detection for non-WPA2
892 * added support for setting static WEP keys for IEEE 802.1X without
893 dynamic WEP keying (eapol_flags=0)
896 * added support for reading PKCS#12 (PFX) files (as a replacement for
897 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
898 * fixed compilation with CONFIG_PCSC=y
899 * added new ap_scan mode, ap_scan=2, for drivers that take care of
900 association, but need to be configured with security policy and SSID,
901 e.g., ndiswrapper and NDIS driver; this mode should allow such
902 drivers to work with hidden SSIDs and optimized roaming; when
903 ap_scan=2 is used, only the first network block in the configuration
904 file is used and this configuration should have explicit security
905 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
906 group, proto variables
907 * added experimental port of wpa_supplicant for Windows
908 - driver_ndis.c driver interface (NDIS OIDs)
909 - currently, this requires cygwin and WinPcap
910 - small utility, win_if_list, can be used to get interface name
911 * control interface can now be removed at build time; add
912 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
913 * optional Xsupplicant interface can now be removed at build time;
914 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
915 * added auth_alg to driver interface associate() parameters to make it
916 easier for drivers to configure authentication algorithm as part of
919 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
920 * driver_broadcom: added new driver interface for Broadcom wl.o driver
921 (a generic driver for Broadcom IEEE 802.11a/g cards)
922 * wpa_cli: fixed parsing of -p <path> command line argument
923 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
924 ACK, not tunneled EAP-Success (of which only the first byte was
925 actually send due to a bug in previous code); this seems to
926 interoperate with most RADIUS servers that implements PEAPv1
927 * PEAPv1: added support for terminating PEAP authentication on tunneled
928 EAP-Success message; this can be configured by adding
929 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
930 (some RADIUS servers require this whereas others require a tunneled
932 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
933 the old label for key derivation; previously, the default was 1,
934 but it looks like most existing PEAPv1 implementations use the old
935 label which is thus more suitable default option
936 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
937 * fixed parsing of wep_tx_keyidx
938 * added support for configuring list of allowed Phase 2 EAP types
939 (for both EAP-PEAP and EAP-TTLS) instead of only one type
940 * added support for configuring IEEE 802.11 authentication algorithm
941 (auth_alg; mainly for using Shared Key authentication with static
943 * added support for EAP-AKA (with UMTS SIM)
944 * fixed couple of errors in PCSC handling that could have caused
945 random-looking errors for EAP-SIM
946 * added support for EAP-SIM pseudonyms and fast re-authentication
947 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
949 * added support for EAP-SIM with two challanges
950 (phase1="sim_min_num_chal=3" can be used to require three challenges)
951 * added support for configuring DH/DSA parameters for an ephemeral DH
952 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
953 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
954 and optional DH key exchange to achieve forward secracy with RSA keys
955 * added support for matching subject of the authentication server
956 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
957 configuration variables subject_match and subject_match2
958 * changed SSID configuration in driver_wext.c (used by many driver
959 interfaces) to use ssid_len+1 as the length for SSID since some Linux
961 * fixed couple of unaligned reads in scan result parsing to fix WPA
962 connection on some platforms (e.g., ARM)
963 * added driver interface for Intel ipw2100 driver
964 * added support for LEAP with WPA
965 * added support for larger scan results report (old limit was 4 kB of
966 data, i.e., about 35 or so APs) when using Linux wireless extensions
968 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
969 only if there is a PMKSA cache entry for the current AP
970 * fixed error handling for case where reading of scan results fails:
971 must schedule a new scan or wpa_supplicant will remain waiting
973 * changed debug output to remove shared password/key material by
974 default; all key information can be included with -K command line
975 argument to match the previous behavior
976 * added support for timestamping debug log messages (disabled by
977 default, can be enabled with -t command line argument)
978 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
979 if keys are not configured to be used; this fixes IEEE 802.1X mode
980 with drivers that use this information to configure whether Privacy
981 bit can be in Beacon frames (e.g., ndiswrapper)
982 * avoid clearing driver keys if no keys have been configured since last
983 key clear request; this seems to improve reliability of group key
984 handshake for ndiswrapper & NDIS driver which seems to be suffering
985 of some kind of timing issue when the keys are cleared again after
987 * changed driver interface API:
988 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
989 version is being used (now, this is set to 2; previously, it was
991 - pass pointer to private data structure to all calls
992 - the new API is not backwards compatible; all in-tree driver
993 interfaces has been converted to the new API
994 * added support for controlling multiple interfaces (radios) per
995 wpa_supplicant process; each interface needs to be listed on the
996 command line (-c, -i, -D arguments) with -N as a separator
997 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
998 * added a workaround for EAP servers that incorrectly use same Id for
999 sequential EAP packets
1000 * changed libpcap/libdnet configuration to use .config variable,
1001 CONFIG_DNET_PCAP, instead of requiring Makefile modification
1002 * improved downgrade attack detection in IE verification of msg 3/4:
1003 verify both WPA and RSN IEs, if present, not only the selected one;
1004 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
1005 Probe Response frame, and RSN is enabled in wpa_supplicant
1007 * fixed WPA msg 3/4 processing to allow Key Data field contain other
1008 IEs than just one WPA IE
1009 * added support for FreeBSD and driver interface for the BSD net80211
1010 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
1011 required kernel mods have not yet been committed
1012 * made EAP workarounds configurable; enabled by default, can be
1013 disabled with network block option eap_workaround=0
1015 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
1016 * resolved couple of interoperability issues with EAP-PEAPv1 and
1017 Phase 2 (inner EAP) fragment reassembly
1018 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
1019 AP is using non-zero key index for the unicast key and key index zero
1020 for the broadcast key
1021 * driver_hostap: fixed IEEE 802.1X WEP key updates and
1022 re-authentication by allowing unencrypted EAPOL frames when not using
1024 * added a new driver interface, 'wext', which uses only standard,
1025 driver independent functionality in Linux wireless extensions;
1026 currently, this can be used only for non-WPA IEEE 802.1X mode, but
1027 eventually, this is to be extended to support full WPA/WPA2 once
1028 Linux wireless extensions get support for this
1029 * added support for mode in which the driver is responsible for AP
1030 scanning and selection; this is disabled by default and can be
1031 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
1032 this mode can be used, e.g., with generic 'wext' driver interface to
1033 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
1034 supporting wireless extensions.
1035 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
1036 operation with an AP that does not include SSID in the Beacon frames)
1037 * added support for new EAP authentication methods:
1038 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
1039 * added support for asking one-time-passwords from frontends (e.g.,
1040 wpa_cli); this 'otp' command works otherwise like 'password' command,
1041 but the password is used only once and the frontend will be asked for
1042 a new password whenever a request from authenticator requires a
1043 password; this can be used with both EAP-OTP and EAP-GTC
1044 * changed wpa_cli to automatically re-establish connection so that it
1045 does not need to be re-started when wpa_supplicant is terminated and
1047 * improved user data (identity/password/otp) requests through
1048 frontends: process pending EAPOL packets after getting new
1049 information so that full authentication does not need to be
1050 restarted; in addition, send pending requests again whenever a new
1051 frontend is attached
1052 * changed control frontends to use a new directory for socket files to
1053 make it easier for wpa_cli to automatically select between interfaces
1054 and to provide access control for the control interface;
1055 wpa_supplicant.conf: ctrl_interface is now a path
1056 (/var/run/wpa_supplicant is the recommended path) and
1057 ctrl_interface_group can be used to select which group gets access to
1058 the control interface;
1059 wpa_cli: by default, try to connect to the first interface available
1060 in /var/run/wpa_supplicant; this path can be overriden with -p option
1061 and an interface can be selected with -i option (i.e., in most common
1062 cases, wpa_cli does not need to get any arguments)
1063 * added support for LEAP
1064 * added driver interface for Linux ndiswrapper
1065 * added priority option for network blocks in the configuration file;
1066 this allows networks to be grouped based on priority (the scan
1067 results are searched for matches with network blocks in this order)
1070 * sort scan results to improve AP selection
1071 * fixed control interface socket removal for some error cases
1072 * improved scan requesting and authentication timeout
1073 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1075 * PEAP version can now be forced with phase1="peapver=<ver>"
1076 (mostly for testing; by default, the highest version supported by
1077 both the Supplicant and Authentication Server is selected
1079 * added support for madwifi driver (Atheros ar521x)
1080 * added a workaround for cases where AP sets Install Tx/Rx bit for
1081 WPA Group Key messages when pairwise keys are used (without this,
1082 the Group Key would be used for Tx and the AP would drop frames
1084 * added GSM SIM/USIM interface for GSM authentication algorithm for
1085 EAP-SIM; this requires pcsc-lite
1086 * added support for ATMEL AT76C5XXx driver
1087 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1088 does not include key data in the EAPOL-Key frame (i.e., part of
1089 EAP keying material is used as data encryption key)
1090 * added support for using plaintext and static WEP networks
1094 * added support for new EAP authentication methods:
1095 EAP-TTLS/EAP-MD5-Challenge
1097 EAP-TTLS/EAP-MSCHAPv2
1105 EAP-PEAP/MD5-Challenge
1107 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1108 * added support for anonymous identity (to be used when identity is
1109 sent in plaintext; real identity will be used within TLS protected
1110 tunnel (e.g., with EAP-TTLS)
1111 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1112 * added support for requesting identity and password information using
1113 control interface; in other words, the password for EAP-PEAP or
1114 EAP-TTLS does not need to be included in the configuration file since
1115 a frontand (e.g., wpa_cli) can ask it from the user
1116 * improved RSN pre-authentication to use a candidate list and process
1117 all candidates from each scan; not only one per scan
1118 * fixed RSN IE and WPA IE capabilities field parsing
1119 * ignore Tx bit in GTK IE when Pairwise keys are used
1120 * avoid making new scan requests during IEEE 802.1X negotiation
1121 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1122 with TLS support (this replaces the included implementation with
1123 library code to save about 8 kB since the library code is needed
1125 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1126 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1129 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1131 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1132 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1133 - EAP-MD5 (cannot be used with WPA-RADIUS)
1134 [draft-ietf-eap-rfc2284bis-09.txt]
1135 - EAP-TLS [RFC 2716]
1136 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1137 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1138 [draft-kamath-pppext-eap-mschapv2-00.txt]
1139 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1140 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1141 - new configuration file options: eap, identity, password, ca_cert,
1142 client_cert, privatekey, private_key_passwd
1143 - Xsupplicant is not required anymore, but it can be used by
1144 disabling the internal IEEE 802.1X Supplicant with -e command line
1146 - this code is not included in the default build; Makefile need to
1147 be edited for this (uncomment lines for selected functionality)
1148 - EAP-TLS and EAP-PEAP require openssl libraries
1149 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1150 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1151 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1152 EAPOL-Key frames instead of WPA key handshakes)
1153 * added support for IEEE 802.11i/RSN (WPA2)
1154 - improved PTK Key Handshake
1155 - PMKSA caching, pre-authentication
1156 * fixed wpa_supplicant to ignore possible extra data after WPA
1157 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1158 TPTK' error from message 3 of 4-Way Handshake in case the AP
1159 includes extra data after the EAPOL-Key)
1160 * added interface for external programs (frontends) to control
1162 - CLI example (wpa_cli) with interactive mode and command line
1164 - replaced SIGUSR1 status/statistics with the new control interface
1165 * made some feature compile time configurable
1166 - .config file for make
1167 - driver interfaces (hostap, hermes, ..)
1168 - EAPOL/EAP functions
1171 * Initial version of wpa_supplicant
