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
13 * added support for Wi-Fi Protected Setup (WPS)
14 (wpa_supplicant can now be configured to act as a WPS Enrollee to
15 enroll credentials for a network using PIN and PBC methods; in
16 addition, wpa_supplicant can act as a wireless WPS Registrar to
17 configure an AP); WPS support can be enabled by adding CONFIG_WPS=y
18 into .config and setting the runtime configuration variables in
19 wpa_supplicant.conf (see WPS section in the example configuration
20 file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to
21 manage WPS negotiation; see README-WPS for more details
22 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
23 * added support for using driver_test over UDP socket
24 * fixed PEAPv0 Cryptobinding interoperability issue with Windows Server
25 2008 NPS; optional cryptobinding is now enabled (again) by default
26 * fixed PSK editing in wpa_gui
27 * changed EAP-GPSK to use the IANA assigned EAP method type 51
28 * added a Windows installer that includes WinPcap and all the needed
29 DLLs; in addition, it set up the registry automatically so that user
30 will only need start wpa_gui to get prompted to start the wpasvc
31 servide and add a new interface if needed through wpa_gui dialog
32 * updated management frame protection to use IEEE 802.11w/D7.0
35 * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
36 (can be used to simulate test SIM/USIM card with a known private key;
37 enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
38 and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
39 * added a new network configuration option, wpa_ptk_rekey, that can be
40 used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
41 against TKIP deficiencies
42 * added an optional mitigation mechanism for certain attacks against
43 TKIP by delaying Michael MIC error reports by a random amount of time
44 between 0 and 60 seconds; this can be enabled with a build option
45 CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
46 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
48 * updated OpenSSL code for EAP-FAST to use an updated version of the
49 session ticket overriding API that was included into the upstream
50 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
51 needed with that version anymore)
52 * updated userspace MLME instructions to match with the current Linux
53 mac80211 implementation; please also note that this can only be used
54 with driver_nl80211.c (the old code from driver_wext.c was removed)
55 * added support (Linux only) for RoboSwitch chipsets (often found in
56 consumer grade routers); driver interface 'roboswitch'
57 * fixed canceling of PMKSA caching when using drivers that generate
58 RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
62 * added support for SHA-256 as X.509 certificate digest when using the
63 internal X.509/TLSv1 implementation
64 * updated management frame protection to use IEEE 802.11w/D6.0
65 * added support for using SHA256-based stronger key derivation for WPA2
67 * fixed FT (IEEE 802.11r) authentication after a failed association to
69 * added support for configuring Phase 2 (inner/tunneled) authentication
70 method with wpa_gui-qt4
73 * added support for EAP Sequences in EAP-FAST Phase 2
74 * added support for using TNC with EAP-FAST
75 * added driver_ps3 for the PS3 Linux wireless driver
76 * added support for optional cryptobinding with PEAPv0
77 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
78 allow fallback to full handshake if server rejects PAC-Opaque
79 * added fragmentation support for EAP-TNC
80 * added support for parsing PKCS #8 formatted private keys into the
81 internal TLS implementation (both PKCS #1 RSA key and PKCS #8
82 encapsulated RSA key can now be used)
83 * added option of using faster, but larger, routines in the internal
84 LibTomMath (for internal TLS implementation) to speed up DH and RSA
85 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
86 * fixed race condition between disassociation event and group key
87 handshake to avoid getting stuck in incorrect state [Bug 261]
88 * fixed opportunistic key caching (proactive_key_caching)
91 * removed 'nai' and 'eappsk' network configuration variables that were
92 previously used for configuring user identity and key for EAP-PSK,
93 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
94 replacement for 'nai' (if old configuration used a separate
95 'identity' value, that would now be configured as
96 'anonymous_identity'). 'password' field is now used as the
97 replacement for 'eappsk' (it can also be set using hexstring to
98 present random binary data)
99 * removed '-w' command line parameter (wait for interface to be added,
100 if needed); cleaner way of handling this functionality is to use an
101 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
102 when an interface is added
103 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
104 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
105 indicating when new scan results become available
106 * added new ctrl_iface command, BSS, to allow scan results to be
107 fetched without hitting the message size limits (this command
108 can be used to iterate through the scan results one BSS at the time)
109 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
110 attributes in EAP-SIM Start/Response when using fast reauthentication
111 * fixed EAPOL not to end up in infinite loop when processing dynamic
112 WEP keys with IEEE 802.1X
113 * fixed problems in getting NDIS events from WMI on Windows 2000
116 * added support for Makefile builds to include debug-log-to-a-file
117 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
118 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
119 lengths properly to avoid potential crash caused by invalid messages
120 * added data structure for storing allocated buffers (struct wpabuf);
121 this does not affect wpa_supplicant usage, but many of the APIs
122 changed and various interfaces (e.g., EAP) is not compatible with old
124 * added support for protecting EAP-AKA/Identity messages with
125 AT_CHECKCODE (optional feature in RFC 4187)
126 * added support for protected result indication with AT_RESULT_IND for
127 EAP-SIM and EAP-AKA (phase1="result_ind=1")
128 * added driver_wext workaround for race condition between scanning and
129 association with drivers that take very long time to scan all
130 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
131 using a longer hardcoded timeout for the scan if the driver supports
132 notifications for scan completion (SIOCGIWSCAN event); this helps,
133 e.g., in cases where wpa_supplicant and madwifi driver ended up in
134 loop where the driver did not even try to associate
135 * stop EAPOL timer tick when no timers are in use in order to reduce
136 power consumption (no need to wake up the process once per second)
138 * added support for privilege separation (run only minimal part of
139 wpa_supplicant functionality as root and rest as unprivileged,
140 non-root process); see 'Privilege separation' in README for details;
141 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
143 * changed scan results data structure to include all information
144 elements to make it easier to support new IEs; old get_scan_result()
145 driver_ops is still supported for backwards compatibility (results
146 are converted internally to the new format), but all drivers should
147 start using the new get_scan_results2() to make them more likely to
148 work with new features
149 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
150 application, i.e., it does not require Qt3Support anymore; Windows
151 binary of wpa_gui.exe is now from this directory and only requires
152 QtCore4.dll and QtGui4.dll libraries
153 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
154 available as a separate package to make wpa_gui installation easier:
155 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
156 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
157 only shared key/password authentication is supported in this version
160 * added support for configuring password as NtPasswordHash
161 (16-byte MD4 hash of password) in hash:<32 hex digits> format
162 * added support for fallback from abbreviated TLS handshake to
163 full handshake when using EAP-FAST (e.g., due to an expired
165 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
166 draft (draft-ietf-emu-eap-gpsk-07.txt)
167 * added support for drivers that take care of RSN 4-way handshake
168 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
169 WPA_ALG_PMK in set_key)
170 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
171 .config); this version supports only ap_scan=2 mode and allow the
172 driver to take care of the 4-way handshake
173 * fixed a buffer overflow in parsing TSF from scan results when using
174 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
176 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
177 * fixed an integer overflow issue in the ASN.1 parser used by the
178 (experimental) internal TLS implementation to avoid a potential
180 * fixed a race condition with -W option (wait for a control interface
181 monitor before starting) that could have caused the first messages to
183 * added support for processing TNCC-TNCS-Messages to report
184 recommendation (allow/none/isolate) when using TNC [Bug 243]
187 * added network configuration parameter 'frequency' for setting
188 initial channel for IBSS (adhoc) networks
189 * added experimental IEEE 802.11r/D6.0 support
190 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
191 * updated EAP-PSK to use the IANA-allocated EAP type 47
192 * fixed EAP-PAX key derivation
193 * fixed EAP-PSK bit ordering of the Flags field
194 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
195 tunnelled identity request (previously, the identifier from the outer
196 method was used, not the tunnelled identifier which could be
198 * added support for fragmentation of outer TLS packets during Phase 2
199 of EAP-PEAP/TTLS/FAST
200 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
201 * added support for EAP-FAST authentication with inner methods that
202 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
203 for PAC provisioning)
204 * added support for authenticated EAP-FAST provisioning
205 * added support for configuring maximum number of EAP-FAST PACs to
206 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
207 * added support for storing EAP-FAST PACs in binary format
208 (fast_pac_format=binary in phase1 string)
209 * fixed dbus ctrl_iface to validate message interface before
210 dispatching to avoid a possible segfault [Bug 190]
211 * fixed PeerKey key derivation to use the correct PRF label
212 * updated Windows binary build to link against OpenSSL 0.9.8d and
213 added support for EAP-FAST
214 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
215 draft (draft-ietf-emu-eap-gpsk-04.txt)
216 * fixed EAP-AKA Notification processing to allow Notification to be
217 processed after AKA Challenge response has been sent
218 * updated to use IEEE 802.11w/D2.0 for management frame protection
220 * fixed EAP-TTLS implementation not to crash on use of freed memory
221 if TLS library initialization fails
222 * added support for EAP-TNC (Trusted Network Connect)
223 (this version implements the EAP-TNC method and EAP-TTLS changes
224 needed to run two methods in sequence (IF-T) and the IF-IMC and
225 IF-TNCCS interfaces from TNCC)
228 * added experimental, integrated TLSv1 client implementation with the
229 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
230 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
231 .config); this can be useful, e.g., if the target system does not
232 have a suitable TLS library and a minimal code size is required
233 (total size of this internal TLS/crypto code is bit under 50 kB on
234 x86 and the crypto code is shared by rest of the supplicant so some
235 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
236 * removed STAKey handshake since PeerKey handshake has replaced it in
237 IEEE 802.11ma and there are no known deployments of STAKey
238 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
239 draft (draft-ietf-emu-eap-gpsk-01.txt)
240 * added preliminary implementation of IEEE 802.11w/D1.0 (management
242 (Note: this requires driver support to work properly.)
243 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
244 * fixed Windows named pipes ctrl_iface to not stop listening for
245 commands if client program opens a named pipe and closes it
246 immediately without sending a command
247 * fixed USIM PIN status determination for the case that PIN is not
248 needed (this allows EAP-AKA to be used with USIM cards that do not
250 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
251 be used with cards that do not support file selection based on
253 * added support for matching the subjectAltName of the authentication
254 server certificate against multiple name components (e.g.,
255 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
256 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
257 affects IEEE 802.1X with dynamic WEP keys)
258 * changed ctrl_iface network configuration 'get' operations to not
259 return password/key material; if these fields are requested, "*"
260 will be returned if the password/key is set, but the value of the
261 parameter is not exposed
264 * added support for building Windows version with UNICODE defined
265 (wide-char functions)
266 * driver_ndis: fixed static WEP configuration to avoid race condition
267 issues with some NDIS drivers between association and setting WEP
269 * driver_ndis: added validation for IELength value in scan results to
270 avoid crashes when using buggy NDIS drivers [Bug 165]
271 * fixed Release|Win32 target in the Visual Studio project files
272 (previously, only Debug|Win32 target was set properly)
273 * changed control interface API call wpa_ctrl_pending() to allow it to
274 return -1 on error (e.g., connection lost); control interface clients
275 will need to make sure that they verify that the value is indeed >0
276 when determining whether there are pending messages
277 * added an alternative control interface backend for Windows targets:
278 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
279 control interface mechanism for Windows builds (previously, UDP to
281 * changed ctrl_interface configuration for UNIX domain sockets:
282 - deprecated ctrl_interface_group variable (it may be removed in
284 - allow both directory and group be configured with ctrl_interface
285 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
286 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
287 case when group is not changed
288 * added support for controlling more than one interface per process in
290 * added a workaround for a case where the AP is using unknown address
291 (e.g., MAC address of the wired interface) as the source address for
292 EAPOL-Key frames; previously, that source address was used as the
293 destination for EAPOL-Key frames and in key derivation; now, BSSID is
294 used even if the source address does not match with it
295 (this resolves an interoperability issue with Thomson SpeedTouch 580)
296 * added a workaround for UDP-based control interface (which was used in
297 Windows builds before this release) to prevent packets with forged
298 addresses from being accepted as local control requests
299 * removed ndis_events.cpp and possibility of using external
300 ndis_events.exe; C version (ndis_events.c) is fully functional and
301 there is no desire to maintain two separate versions of this
303 * ndis_events: Changed NDIS event notification design to use WMI to
304 learn the adapter description through Win32_PnPEntity class; this
305 should fix some cases where the adapter name was not recognized
306 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
308 * fixed selection of the first network in ap_scan=2 mode; previously,
309 wpa_supplicant could get stuck in SCANNING state when only the first
310 network for enabled (e.g., after 'wpa_cli select_network 0')
311 * winsvc: added support for configuring ctrl_interface parameters in
312 registry (ctrl_interface string value in
313 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
314 required to enable control interface (previously, this was hardcoded
316 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
317 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
320 * fixed build with CONFIG_STAKEY=y [Bug 143]
321 * added support for doing MLME (IEEE 802.11 management frame
322 processing) in wpa_supplicant when using Devicescape IEEE 802.11
323 stack (wireless-dev.git tree)
324 * added a new network block configuration option, fragment_size, to
325 configure the maximum EAP fragment size
326 * driver_ndis: Disable WZC automatically for the selected interface to
327 avoid conflicts with two programs trying to control the radio; WZC
328 will be re-enabled (if it was enabled originally) when wpa_supplicant
330 * added an experimental TLSv1 client implementation
331 (CONFIG_TLS=internal) that can be used instead of an external TLS
332 library, e.g., to reduce total size requirement on systems that do
333 not include any TLS library by default (this is not yet complete;
334 basic functionality is there, but certificate validation is not yet
336 * added PeerKey handshake implementation for IEEE 802.11e
337 direct link setup (DLS) to replace STAKey handshake
338 * fixed WPA PSK update through ctrl_iface for the case where the old
339 PSK was derived from an ASCII passphrase and the new PSK is set as
340 a raw PSK (hex string)
341 * added new configuration option for identifying which network block
342 was used (id_str in wpa_supplicant.conf; included on
343 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
344 variable in wpa_cli action scripts; in addition WPA_ID variable is
345 set to the current unique identifier that wpa_supplicant assigned
346 automatically for the network and that can be used with
347 GET_NETWORK/SET_NETWORK ctrl_iface commands)
348 * wpa_cli action script is now called only when the connect/disconnect
349 status changes or when associating with a different network
350 * fixed configuration parser not to remove CCMP from group cipher list
351 if WPA-None (adhoc) is used (pairwise=NONE in that case)
352 * fixed integrated NDIS events processing not to hang the process due
353 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
354 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
355 draft-clancy-emu-eap-shared-secret-00.txt)
356 * added Microsoft Visual Studio 2005 solution and project files for
357 build wpa_supplicant for Windows (see vs2005 subdirectory)
358 * eloop_win: fixed unregistration of Windows events
359 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
360 at the end of RSN pre-authentication and added unregistration of
361 a Windows event to avoid getting eloop_win stuck with an invalid
363 * driver_ndis: added support for selecting AP based on BSSID
364 * added new environmental variable for wpa_cli action scripts:
365 WPA_CTRL_DIR is the current control interface directory
366 * driver_ndis: added support for using NDISUIO instead of WinPcap for
367 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
368 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
369 wpa_supplicant without requiring WinPcap; note that using NDISUIO
370 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
371 only one application to open the device
372 * changed NDIS driver naming to only include device GUID, e.g.,
373 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
374 specific \Device\NPF_ prefix before the GUID; the prefix is still
375 allowed for backwards compatibility, but it is not required anymore
376 when specifying the interface
377 * driver_ndis: re-initialize driver interface is the adapter is removed
378 and re-inserted [Bug 159]
379 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
380 big endian hosts [Bug 146]
383 * fixed EAP-GTC response to include correct user identity when run as
384 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
385 * driver_ndis: Fixed encryption mode configuration for unencrypted
386 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
387 refused to associate with open networks) [Bug 106]
388 * driver_ndis: use BSSID OID polling to detect when IBSS network is
389 formed even when ndis_events code is included since some NDIS drivers
390 do not generate media connect events in IBSS mode
391 * config_winreg: allow global ctrl_interface parameter to be configured
393 * config_winreg: added support for saving configuration data into
395 * added support for controlling network device operational state
396 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
397 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
398 that can use this information)
399 * driver_wext: added support for WE-21 change to SSID configuration
400 * driver_wext: fixed privacy configuration for static WEP keys mode
402 * added an optional driver_ops callback for MLME-SETPROTECTION.request
404 * added support for EAP-SAKE (no EAP method number allocated yet, so
405 this is using the same experimental type 255 as EAP-PSK)
406 * added support for dynamically loading EAP methods (.so files) instead
407 of requiring them to be statically linked in; this is disabled by
408 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
412 * do not try to use USIM APDUs when initializing PC/SC for SIM card
413 access for a network that has not enabled EAP-AKA
414 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
415 v0.5.1 due to the new support for expanded EAP types)
416 * added support for generating EAP Expanded Nak
417 * try to fetch scan results once before requesting new scan when
418 starting up in ap_scan=1 mode (this can speed up initial association
419 a lot with, e.g., madwifi-ng driver)
420 * added support for receiving EAPOL frames from a Linux bridge
421 interface (-bbr0 on command line)
422 * fixed EAPOL re-authentication for sessions that used PMKSA caching
423 * changed EAP method registration to use a dynamic list of methods
424 instead of a static list generated at build time
425 * fixed PMKSA cache deinitialization not to use freed memory when
426 removing PMKSA entries
427 * fixed a memory leak in EAP-TTLS re-authentication
428 * reject WPA/WPA2 message 3/4 if it does not include any valid
430 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
431 if the driver does not support SIOCSIWAUTH
434 * driver_test: added better support for multiple APs and STAs by using
435 a directory with sockets that include MAC address for each device in
436 the name (driver_param=test_dir=/tmp/test)
437 * added support for EAP expanded type (vendor specific EAP methods)
438 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
439 option can be changed if needed
440 * wpa_cli/wpa_gui: skip non-socket files in control directory when
441 using UNIX domain sockets; this avoids selecting an incorrect
442 interface (e.g., a PID file could be in this directory, even though
443 use of this directory for something else than socket files is not
445 * fixed TLS library deinitialization after RSN pre-authentication not
446 to disable TLS library for normal authentication
447 * driver_wext: Remove null-termination from SSID length if the driver
448 used it; some Linux drivers do this and they were causing problems in
449 wpa_supplicant not finding matching configuration block. This change
450 would break a case where the SSID actually ends in '\0', but that is
451 not likely to happen in real use.
452 * fixed PMKSA cache processing not to trigger deauthentication if the
453 current PMKSA cache entry is replaced with a valid new entry
454 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
455 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
458 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
459 * added experimental STAKey handshake implementation for IEEE 802.11e
460 direct link setup (DLS); note: this is disabled by default in both
461 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
463 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
464 decrypt AT_ENCR_DATA attributes correctly
465 * fixed EAP-AKA to allow resynchronization within the same session
466 * made code closer to ANSI C89 standard to make it easier to port to
467 other C libraries and compilers
468 * started moving operating system or C library specific functions into
469 wrapper functions defined in os.h and implemented in os_*.c to make
471 * wpa_supplicant can now be built with Microsoft Visual C++
472 (e.g., with the freely available Toolkit 2003 version or Visual
473 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
474 example makefile for nmake
475 * added support for using Windows registry for command line parameters
476 (CONFIG_MAIN=main_winsvc) and configuration data
477 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
478 contents; this version can be run both as a Windows service and as a
479 normal application; 'wpasvc.exe app' to start as applicant,
480 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
481 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
483 * made it possible to link ndis_events.exe functionality into
484 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
485 * added better support for multiple control interface backends
486 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
487 * fixed PC/SC code to use correct length for GSM AUTH command buffer
488 and to not use pioRecvPci with SCardTransmit() calls; these were not
489 causing visible problems with pcsc-lite, but Windows Winscard.dll
490 refused the previously used parameters; this fixes EAP-SIM and
491 EAP-AKA authentication using SIM/USIM card under Windows
492 * added new event loop implementation for Windows using
493 WaitForMultipleObject() instead of select() in order to allow waiting
494 for non-socket objects; this can be selected with
495 CONFIG_ELOOP=eloop_win in .config
496 * added support for selecting l2_packet implementation in .config
497 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
498 winpcap, freebsd, none)
499 * added new l2_packet implementation for WinPcap
500 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
501 reduce latency in EAPOL receive processing from about 100 ms to about
503 * added support for EAP-FAST key derivation using other ciphers than
504 RC4-128-SHA for authentication and AES128-SHA for provisioning
505 * added support for configuring CA certificate as DER file and as a
507 * fixed private key configuration as configuration blob and added
508 support for using PKCS#12 as a blob
509 * tls_gnutls: added support for using PKCS#12 files; added support for
511 * added support for loading trusted CA certificates from Windows
512 certificate store: ca_cert="cert_store://<name>", where <name> is
513 likely CA (Intermediate CA certificates) or ROOT (root certificates)
514 * added C version of ndis_events.cpp and made it possible to build this
515 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
516 easily on cross-compilation builds
517 * added wpasvc.exe into Windows binary release; this is an alternative
518 version of wpa_supplicant.exe with configuration backend using
519 Windows registry and with the entry point designed to run as a
521 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
522 wpasvc.exe and removed this additional tool from the Windows binary
523 release since it is not needed anymore
524 * load winscard.dll functions dynamically when building with MinGW
525 since MinGW does not yet include winscard library
527 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
528 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
529 and WinPcap to receive frames sent to PAE group address
530 * disable EAP state machine when IEEE 802.1X authentication is not used
531 in order to get rid of bogus "EAP failed" messages
532 * fixed OpenSSL error reporting to go through all pending errors to
533 avoid confusing reports of old errors being reported at later point
535 * fixed configuration file updating to not write empty variables
536 (e.g., proto or key_mgmt) that the file parser would not accept
537 * fixed ADD_NETWORK ctrl_iface command to use the same default values
538 for variables as empty network definitions read from config file
540 * fixed EAP state machine to not discard EAP-Failure messages in many
541 cases (e.g., during TLS handshake)
542 * fixed a infinite loop in private key reading if the configured file
543 cannot be parsed successfully
544 * driver_madwifi: added support for madwifi-ng
545 * wpa_gui: do not display password/PSK field contents
546 * wpa_gui: added CA certificate configuration
547 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
548 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
549 the new AP is using different WPA/RSN IE
550 * use longer timeout for IEEE 802.11 association to avoid problems with
551 drivers that may take more than five second to associate
554 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
555 RSN IE, but WPA IE would match with wpa_supplicant configuration
556 * added support for named configuration blobs in order to avoid having
557 to use file system for external files (e.g., certificates);
558 variables can be set to "blob://<blob name>" instead of file path to
559 use a named blob; supported fields: pac_file, client_cert,
561 * fixed RSN pre-authentication (it was broken in the clean up of WPA
562 state machine interface in v0.4.5)
563 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
564 sure the driver configures broadcast decryption correctly
565 * added ca_path (and ca_path2) configuration variables that can be used
566 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
567 system-wide trusted CA list
568 * added support for starting wpa_supplicant without a configuration
569 file (-C argument must be used to set ctrl_interface parameter for
570 this case; in addition, -p argument can be used to provide
571 driver_param; these new arguments can also be used with a
572 configuration to override the values from the configuration)
573 * added global control interface that can be optionally used for adding
574 and removing network interfaces dynamically (-g command line argument
575 for both wpa_supplicant and wpa_cli) without having to restart
576 wpa_supplicant process
578 - try to save configuration whenever something is modified
579 - added WEP key configuration
580 - added possibility to edit the current network configuration
581 * driver_ndis: fixed driver polling not to increase frequency on each
582 received EAPOL frame due to incorrectly cancelled timeout
583 * added simple configuration file examples (in examples subdirectory)
584 * fixed driver_wext.c to filter wireless events based on ifindex to
585 avoid interfaces receiving events from other interfaces
586 * delay sending initial EAPOL-Start couple of seconds to speed up
587 authentication for the most common case of Authenticator starting
588 EAP authentication immediately after association
591 * added a workaround for clearing keys with ndiswrapper to allow
592 roaming from WPA enabled AP to plaintext one
593 * added docbook documentation (doc/docbook) that can be used to
594 generate, e.g., man pages
595 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
596 PF_PACKET in order to prepare for network devices that do not use
597 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
598 * use receipt of EAPOL-Key frame as a lower layer success indication
599 for EAP state machine to allow recovery from dropped EAP-Success
601 * cleaned up internal EAPOL frame processing by not including link
602 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
603 header is added only when transmitted the frame; this makes it easier
604 to use wpa_supplicant on link layers that use different header than
606 * updated EAP-PSK to use draft 9 by default since this can now be
607 tested with hostapd; removed support for draft 3, including
608 server_nai configuration option from network blocks
609 * driver_wired: add PAE address to the multicast address list in order
610 to be able to receive EAPOL frames with drivers that do not include
611 these multicast addresses by default
612 * driver_wext: add support for WE-19
613 * added support for multiple configuration backends (CONFIG_BACKEND
614 option); currently, only 'file' is supported (i.e., the format used
615 in wpa_supplicant.conf)
616 * added support for updating configuration ('wpa_cli save_config');
617 this is disabled by default and can be enabled with global
618 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
619 and wpa_gui to store the configuration changes in a permanent store
620 * added GET_NETWORK ctrl_iface command
621 (e.g., 'wpa_cli get_network 0 ssid')
624 * replaced OpenSSL patch for EAP-FAST support
625 (openssl-tls-extensions.patch) with a more generic and correct
626 patch (the new patch is not compatible with the previous one, so the
627 OpenSSL library will need to be patched with the new patch in order
628 to be able to build wpa_supplicant with EAP-FAST support)
629 * added support for using Windows certificate store (through CryptoAPI)
630 for client certificate and private key operations (EAP-TLS)
631 (see wpa_supplicant.conf for more information on how to configure
632 this with private_key)
633 * ported wpa_gui to Windows
634 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
635 built with the open source version of the Qt4 for Windows
636 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
637 with drivers that do not support WPA
638 * ndis_events: fixed Windows 2000 support
639 * added support for enabling/disabling networks from the list of all
640 configured networks ('wpa_cli enable_network <network id>' and
641 'wpa_cli disable_network <network id>')
642 * added support for adding and removing network from the current
643 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
644 <network id>'); added networks are disabled by default and they can
645 be enabled with enable_network command once the configuration is done
646 for the new network; note: configuration file is not yet updated, so
647 these new networks are lost when wpa_supplicant is restarted
648 * added support for setting network configuration parameters through
649 the control interface, for example:
650 wpa_cli set_network 0 ssid "\"my network\""
651 * fixed parsing of strings that include both " and # within double
652 quoted area (e.g., "start"#end")
653 * added EAP workaround for PEAP session resumption: allow outer,
654 i.e., not tunneled, EAP-Success to terminate session since; this can
655 be disabled with eap_workaround=0
656 (this was allowed for PEAPv1 before, but now it is also allowed for
657 PEAPv0 since at least one RADIUS authentication server seems to be
658 doing this for PEAPv0, too)
659 * wpa_gui: added preliminary support for adding new networks to the
660 wpa_supplicant configuration (double click on the scan results to
661 open network configuration)
664 * removed interface for external EAPOL/EAP supplicant (e.g.,
665 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
666 anymore and is unlikely to be used by anyone
667 * driver_ndis: fixed WinPcap 3.0 support
668 * fixed build with CONFIG_DNET_PCAP=y on Linux
669 * l2_packet: moved different implementations into separate files
673 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
674 (note: ipw2100-1.1.0 is likely to require an update to work with
676 * added support for using ap_scan=2 mode with multiple network blocks;
677 wpa_supplicant will go through the networks one by one until the
678 driver reports a successful association; this uses the same order for
679 networks as scan_ssid=1 scans, i.e., the priority field is ignored
680 and the network block order in the file is used instead
681 * fixed a potential issue in RSN pre-authentication ending up using
682 freed memory if pre-authentication times out
683 * added support for matching alternative subject name extensions of the
684 authentication server certificate; new configuration variables
685 altsubject_match and altsubject_match2
686 * driver_ndis: added support for IEEE 802.1X authentication with wired
688 * added support for querying private key password (EAP-TLS) through the
689 control interface (wpa_cli/wpa_gui) if one is not included in the
691 * driver_broadcom: fixed couple of memory leaks in scan result
693 * EAP-PAX is now registered as EAP type 46
694 * fixed EAP-PAX MAC calculation
695 * fixed EAP-PAX CK and ICK key derivation
696 * added support for using password with EAP-PAX (as an alternative to
697 entering key with eappsk); SHA-1 hash of the password will be used as
699 * added support for arbitrary driver interface parameters through the
700 configuration file with a new driver_param field; this adds a new
701 driver_ops function set_param()
702 * added possibility to override l2_packet module with driver interface
703 API (new send_eapol handler); this can be used to implement driver
704 specific TX/RX functions for EAPOL frames
705 * fixed ctrl_interface_group processing for the case where gid is
706 entered as a number, not group name
707 * driver_test: added support for testing hostapd with wpa_supplicant
708 by using test driver interface without any kernel drivers or network
712 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
713 packets to be encrypted; this was apparently broken by the changed
714 ioctl order in v0.4.0
715 * driver_madwifi: added preliminary support for compiling against 'BSD'
716 branch of madwifi CVS tree
717 * added support for EAP-MSCHAPv2 password retries within the same EAP
718 authentication session
719 * added support for password changes with EAP-MSCHAPv2 (used when the
720 password has expired)
721 * added support for reading additional certificates from PKCS#12 files
722 and adding them to the certificate chain
723 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
725 * fixed a possible double free in EAP-TTLS fast-reauthentication when
726 identity or password is entered through control interface
727 * display EAP Notification messages to user through control interface
728 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
729 * added GUI version of wpa_cli, wpa_gui; this is not build
730 automatically with 'make'; use 'make wpa_gui' to build (this requires
731 Qt development tools)
732 * added 'disconnect' command to control interface for setting
733 wpa_supplicant in state where it will not associate before
734 'reassociate' command has been used
735 * added support for selecting a network from the list of all configured
736 networks ('wpa_cli select_network <network id>'; this disabled all
737 other networks; to re-enable, 'wpa_cli select_network any')
738 * added support for getting scan results through control interface
739 * added EAP workaround for PEAPv1 session resumption: allow outer,
740 i.e., not tunneled, EAP-Success to terminate session since; this can
741 be disabled with eap_workaround=0
743 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
744 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
745 used to reduce the size of the wpa_supplicant considerably if
746 debugging code is not needed
747 * fixed EAPOL-Key validation to drop packets with invalid Key Data
748 Length; such frames could have crashed wpa_supplicant due to buffer
750 * added support for wired authentication (IEEE 802.1X on wired
751 Ethernet); driver interface 'wired'
752 * obsoleted set_wpa() handler in the driver interface API (it can be
753 replaced by moving enable/disable functionality into init()/deinit())
754 (calls to set_wpa() are still present for backwards compatibility,
755 but they may be removed in the future)
756 * driver_madwifi: fixed association in plaintext mode
757 * modified the EAP workaround that accepts EAP-Success with incorrect
758 Identifier to be even less strict about verification in order to
759 interoperate with some authentication servers
760 * added support for sending TLS alerts
761 * added support for 'any' SSID wildcard; if ssid is not configured or
762 is set to an empty string, any SSID will be accepted for non-WPA AP
763 * added support for asking PIN (for SIM) from frontends (e.g.,
764 wpa_cli); if a PIN is needed, but not included in the configuration
765 file, a control interface request is sent and EAP processing is
766 delayed until the PIN is available
767 * added support for using external devices (e.g., a smartcard) for
768 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
769 new wpa_supplicant.conf variables:
770 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
771 - network: engine, engine_id, key_id
772 * added experimental support for EAP-PAX
773 * added monitor mode for wpa_cli (-a<path to a program to run>) that
774 allows external commands (e.g., shell scripts) to be run based on
775 wpa_supplicant events, e.g., when authentication has been completed
776 and data connection is ready; other related wpa_cli arguments:
777 -B (run in background), -P (write PID file); wpa_supplicant has a new
778 command line argument (-W) that can be used to make it wait until a
779 control interface command is received in order to avoid missing
781 * added support for opportunistic WPA2 PMKSA key caching (disabled by
782 default, can be enabled with proactive_key_caching=1)
783 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
784 Authenticator rejects PMKSA caching attempt and the driver is not
785 using assoc_info events
786 * added -P<pid file> argument for wpa_supplicant to write the current
787 process id into a file
789 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
790 * added new phase1 option parameter, include_tls_length=1, to force
791 wpa_supplicant to add TLS Message Length field to all TLS messages
792 even if the packet is not fragmented; this may be needed with some
793 authentication servers
794 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
795 using drivers that take care of AP selection (e.g., when using
797 * fixed reprocessing of pending request after ctrl_iface requests for
798 identity/password/otp
799 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
800 EAP-PEAP and EAP-TTLS
801 * all drivers using driver_wext: set interface up and select Managed
802 mode when starting wpa_supplicant; set interface down when exiting
803 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
804 ipw2100 and ipw2200; please note that this also changed the
805 configuration variable in .config to CONFIG_DRIVER_IPW
808 * fixed a busy loop introduced in v0.3.5 for scan result processing
809 when no matching AP is found
812 * added a workaround for an interoperability issue with a Cisco AP
814 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
815 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
816 retransmission of dropped frames)
817 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
818 (e.g., segfault when processing EAPOL-Key frames)
819 * fixed EAP workaround and fast reauthentication configuration for
820 RSN pre-authentication; previously these were disabled and
821 pre-authentication would fail if the used authentication server
822 requires EAP workarounds
823 * added support for blacklisting APs that fail or timeout
824 authentication in ap_scan=1 mode so that all APs are tried in cases
825 where the ones with strongest signal level are failing authentication
826 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
827 authentication attempt
828 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
829 in the previous authentication (previously, only Phase 1 success was
833 * added preliminary support for IBSS (ad-hoc) mode configuration
834 (mode=1 in network block); this included a new key_mgmt mode
835 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
836 key management; see wpa_supplicant.conf for more details and an
837 example on how to configure this (note: this is currently implemented
838 only for driver_hostapd.c, but the changes should be trivial to add
839 in associate() handler for other drivers, too (assuming the driver
841 * added preliminary port for native Windows (i.e., no cygwin) using
845 * added optional support for GNU Readline and History Libraries for
846 wpa_cli (CONFIG_READLINE)
847 * cleaned up EAP state machine <-> method interface and number of
848 small problems with error case processing not terminating on
849 EAP-Failure but waiting for timeout
850 * added couple of workarounds for interoperability issues with a
851 Cisco AP when using WPA2
852 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
853 Note: This requires a patch for openssl to add support for TLS
854 extensions and number of workarounds for operations without
855 certificates. Proof of concept type of experimental patch is
856 included in openssl-tls-extensions.patch.
859 * fixed private key loading for cases where passphrase is not set
860 * fixed Windows/cygwin L2 packet handler freeing; previous version
861 could cause a segfault when RSN pre-authentication was completed
862 * added support for PMKSA caching with drivers that generate RSN IEs
863 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
864 but similar code can be easily added to driver_ndiswrapper.c once
865 ndiswrapper gets full support for RSN PMKSA caching
866 * improved recovery from PMKID mismatches by requesting full EAP
867 authentication in case of failed PMKSA caching attempt
868 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
869 (this requires that ndis_events is ran while wpa_supplicant is
871 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
872 * added support for driver interfaces to replace the interface name
873 based on driver/OS specific mapping, e.g., in case of driver_ndis,
874 this allows the beginning of the adapter description to be used as
876 * added support for CR+LF (Windows-style) line ends in configuration
878 * driver_ndis: enable radio before starting scanning, disable radio
880 * modified association event handler to set portEnabled = FALSE before
881 clearing port Valid in order to reset EAP state machine and avoid
882 problems with new authentication getting ignored because of state
883 machines ending up in AUTHENTICATED/SUCCESS state based on old
885 * added support for driver events to add PMKID candidates in order to
886 allow drivers to give priority to most likely roaming candidates
887 * driver_hostap: moved PrivacyInvoked configuration to associate()
888 function so that this will not be set for plaintext connections
889 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
890 interface can distinguish plaintext and IEEE 802.1X (no WPA)
892 * fixed static WEP key configuration to use broadcast/default type for
893 all keys (previously, the default TX key was configured as pairwise/
895 * driver_ndis: added legacy WPA capability detection for non-WPA2
897 * added support for setting static WEP keys for IEEE 802.1X without
898 dynamic WEP keying (eapol_flags=0)
901 * added support for reading PKCS#12 (PFX) files (as a replacement for
902 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
903 * fixed compilation with CONFIG_PCSC=y
904 * added new ap_scan mode, ap_scan=2, for drivers that take care of
905 association, but need to be configured with security policy and SSID,
906 e.g., ndiswrapper and NDIS driver; this mode should allow such
907 drivers to work with hidden SSIDs and optimized roaming; when
908 ap_scan=2 is used, only the first network block in the configuration
909 file is used and this configuration should have explicit security
910 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
911 group, proto variables
912 * added experimental port of wpa_supplicant for Windows
913 - driver_ndis.c driver interface (NDIS OIDs)
914 - currently, this requires cygwin and WinPcap
915 - small utility, win_if_list, can be used to get interface name
916 * control interface can now be removed at build time; add
917 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
918 * optional Xsupplicant interface can now be removed at build time;
919 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
920 * added auth_alg to driver interface associate() parameters to make it
921 easier for drivers to configure authentication algorithm as part of
924 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
925 * driver_broadcom: added new driver interface for Broadcom wl.o driver
926 (a generic driver for Broadcom IEEE 802.11a/g cards)
927 * wpa_cli: fixed parsing of -p <path> command line argument
928 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
929 ACK, not tunneled EAP-Success (of which only the first byte was
930 actually send due to a bug in previous code); this seems to
931 interoperate with most RADIUS servers that implements PEAPv1
932 * PEAPv1: added support for terminating PEAP authentication on tunneled
933 EAP-Success message; this can be configured by adding
934 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
935 (some RADIUS servers require this whereas others require a tunneled
937 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
938 the old label for key derivation; previously, the default was 1,
939 but it looks like most existing PEAPv1 implementations use the old
940 label which is thus more suitable default option
941 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
942 * fixed parsing of wep_tx_keyidx
943 * added support for configuring list of allowed Phase 2 EAP types
944 (for both EAP-PEAP and EAP-TTLS) instead of only one type
945 * added support for configuring IEEE 802.11 authentication algorithm
946 (auth_alg; mainly for using Shared Key authentication with static
948 * added support for EAP-AKA (with UMTS SIM)
949 * fixed couple of errors in PCSC handling that could have caused
950 random-looking errors for EAP-SIM
951 * added support for EAP-SIM pseudonyms and fast re-authentication
952 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
954 * added support for EAP-SIM with two challanges
955 (phase1="sim_min_num_chal=3" can be used to require three challenges)
956 * added support for configuring DH/DSA parameters for an ephemeral DH
957 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
958 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
959 and optional DH key exchange to achieve forward secracy with RSA keys
960 * added support for matching subject of the authentication server
961 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
962 configuration variables subject_match and subject_match2
963 * changed SSID configuration in driver_wext.c (used by many driver
964 interfaces) to use ssid_len+1 as the length for SSID since some Linux
966 * fixed couple of unaligned reads in scan result parsing to fix WPA
967 connection on some platforms (e.g., ARM)
968 * added driver interface for Intel ipw2100 driver
969 * added support for LEAP with WPA
970 * added support for larger scan results report (old limit was 4 kB of
971 data, i.e., about 35 or so APs) when using Linux wireless extensions
973 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
974 only if there is a PMKSA cache entry for the current AP
975 * fixed error handling for case where reading of scan results fails:
976 must schedule a new scan or wpa_supplicant will remain waiting
978 * changed debug output to remove shared password/key material by
979 default; all key information can be included with -K command line
980 argument to match the previous behavior
981 * added support for timestamping debug log messages (disabled by
982 default, can be enabled with -t command line argument)
983 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
984 if keys are not configured to be used; this fixes IEEE 802.1X mode
985 with drivers that use this information to configure whether Privacy
986 bit can be in Beacon frames (e.g., ndiswrapper)
987 * avoid clearing driver keys if no keys have been configured since last
988 key clear request; this seems to improve reliability of group key
989 handshake for ndiswrapper & NDIS driver which seems to be suffering
990 of some kind of timing issue when the keys are cleared again after
992 * changed driver interface API:
993 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
994 version is being used (now, this is set to 2; previously, it was
996 - pass pointer to private data structure to all calls
997 - the new API is not backwards compatible; all in-tree driver
998 interfaces has been converted to the new API
999 * added support for controlling multiple interfaces (radios) per
1000 wpa_supplicant process; each interface needs to be listed on the
1001 command line (-c, -i, -D arguments) with -N as a separator
1002 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
1003 * added a workaround for EAP servers that incorrectly use same Id for
1004 sequential EAP packets
1005 * changed libpcap/libdnet configuration to use .config variable,
1006 CONFIG_DNET_PCAP, instead of requiring Makefile modification
1007 * improved downgrade attack detection in IE verification of msg 3/4:
1008 verify both WPA and RSN IEs, if present, not only the selected one;
1009 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
1010 Probe Response frame, and RSN is enabled in wpa_supplicant
1012 * fixed WPA msg 3/4 processing to allow Key Data field contain other
1013 IEs than just one WPA IE
1014 * added support for FreeBSD and driver interface for the BSD net80211
1015 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
1016 required kernel mods have not yet been committed
1017 * made EAP workarounds configurable; enabled by default, can be
1018 disabled with network block option eap_workaround=0
1020 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
1021 * resolved couple of interoperability issues with EAP-PEAPv1 and
1022 Phase 2 (inner EAP) fragment reassembly
1023 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
1024 AP is using non-zero key index for the unicast key and key index zero
1025 for the broadcast key
1026 * driver_hostap: fixed IEEE 802.1X WEP key updates and
1027 re-authentication by allowing unencrypted EAPOL frames when not using
1029 * added a new driver interface, 'wext', which uses only standard,
1030 driver independent functionality in Linux wireless extensions;
1031 currently, this can be used only for non-WPA IEEE 802.1X mode, but
1032 eventually, this is to be extended to support full WPA/WPA2 once
1033 Linux wireless extensions get support for this
1034 * added support for mode in which the driver is responsible for AP
1035 scanning and selection; this is disabled by default and can be
1036 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
1037 this mode can be used, e.g., with generic 'wext' driver interface to
1038 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
1039 supporting wireless extensions.
1040 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
1041 operation with an AP that does not include SSID in the Beacon frames)
1042 * added support for new EAP authentication methods:
1043 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
1044 * added support for asking one-time-passwords from frontends (e.g.,
1045 wpa_cli); this 'otp' command works otherwise like 'password' command,
1046 but the password is used only once and the frontend will be asked for
1047 a new password whenever a request from authenticator requires a
1048 password; this can be used with both EAP-OTP and EAP-GTC
1049 * changed wpa_cli to automatically re-establish connection so that it
1050 does not need to be re-started when wpa_supplicant is terminated and
1052 * improved user data (identity/password/otp) requests through
1053 frontends: process pending EAPOL packets after getting new
1054 information so that full authentication does not need to be
1055 restarted; in addition, send pending requests again whenever a new
1056 frontend is attached
1057 * changed control frontends to use a new directory for socket files to
1058 make it easier for wpa_cli to automatically select between interfaces
1059 and to provide access control for the control interface;
1060 wpa_supplicant.conf: ctrl_interface is now a path
1061 (/var/run/wpa_supplicant is the recommended path) and
1062 ctrl_interface_group can be used to select which group gets access to
1063 the control interface;
1064 wpa_cli: by default, try to connect to the first interface available
1065 in /var/run/wpa_supplicant; this path can be overriden with -p option
1066 and an interface can be selected with -i option (i.e., in most common
1067 cases, wpa_cli does not need to get any arguments)
1068 * added support for LEAP
1069 * added driver interface for Linux ndiswrapper
1070 * added priority option for network blocks in the configuration file;
1071 this allows networks to be grouped based on priority (the scan
1072 results are searched for matches with network blocks in this order)
1075 * sort scan results to improve AP selection
1076 * fixed control interface socket removal for some error cases
1077 * improved scan requesting and authentication timeout
1078 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1080 * PEAP version can now be forced with phase1="peapver=<ver>"
1081 (mostly for testing; by default, the highest version supported by
1082 both the Supplicant and Authentication Server is selected
1084 * added support for madwifi driver (Atheros ar521x)
1085 * added a workaround for cases where AP sets Install Tx/Rx bit for
1086 WPA Group Key messages when pairwise keys are used (without this,
1087 the Group Key would be used for Tx and the AP would drop frames
1089 * added GSM SIM/USIM interface for GSM authentication algorithm for
1090 EAP-SIM; this requires pcsc-lite
1091 * added support for ATMEL AT76C5XXx driver
1092 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1093 does not include key data in the EAPOL-Key frame (i.e., part of
1094 EAP keying material is used as data encryption key)
1095 * added support for using plaintext and static WEP networks
1099 * added support for new EAP authentication methods:
1100 EAP-TTLS/EAP-MD5-Challenge
1102 EAP-TTLS/EAP-MSCHAPv2
1110 EAP-PEAP/MD5-Challenge
1112 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1113 * added support for anonymous identity (to be used when identity is
1114 sent in plaintext; real identity will be used within TLS protected
1115 tunnel (e.g., with EAP-TTLS)
1116 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1117 * added support for requesting identity and password information using
1118 control interface; in other words, the password for EAP-PEAP or
1119 EAP-TTLS does not need to be included in the configuration file since
1120 a frontand (e.g., wpa_cli) can ask it from the user
1121 * improved RSN pre-authentication to use a candidate list and process
1122 all candidates from each scan; not only one per scan
1123 * fixed RSN IE and WPA IE capabilities field parsing
1124 * ignore Tx bit in GTK IE when Pairwise keys are used
1125 * avoid making new scan requests during IEEE 802.1X negotiation
1126 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1127 with TLS support (this replaces the included implementation with
1128 library code to save about 8 kB since the library code is needed
1130 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1131 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1134 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1136 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1137 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1138 - EAP-MD5 (cannot be used with WPA-RADIUS)
1139 [draft-ietf-eap-rfc2284bis-09.txt]
1140 - EAP-TLS [RFC 2716]
1141 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1142 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1143 [draft-kamath-pppext-eap-mschapv2-00.txt]
1144 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1145 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1146 - new configuration file options: eap, identity, password, ca_cert,
1147 client_cert, privatekey, private_key_passwd
1148 - Xsupplicant is not required anymore, but it can be used by
1149 disabling the internal IEEE 802.1X Supplicant with -e command line
1151 - this code is not included in the default build; Makefile need to
1152 be edited for this (uncomment lines for selected functionality)
1153 - EAP-TLS and EAP-PEAP require openssl libraries
1154 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1155 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1156 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1157 EAPOL-Key frames instead of WPA key handshakes)
1158 * added support for IEEE 802.11i/RSN (WPA2)
1159 - improved PTK Key Handshake
1160 - PMKSA caching, pre-authentication
1161 * fixed wpa_supplicant to ignore possible extra data after WPA
1162 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1163 TPTK' error from message 3 of 4-Way Handshake in case the AP
1164 includes extra data after the EAPOL-Key)
1165 * added interface for external programs (frontends) to control
1167 - CLI example (wpa_cli) with interactive mode and command line
1169 - replaced SIGUSR1 status/statistics with the new control interface
1170 * made some feature compile time configurable
1171 - .config file for make
1172 - driver interfaces (hostap, hermes, ..)
1173 - EAPOL/EAP functions
1176 * Initial version of wpa_supplicant
