1 ChangeLog for wpa_supplicant
4 * added support for Wi-Fi Protected Setup (WPS)
5 (wpa_supplicant can now be configured to act as a WPS Enrollee to
6 enroll credentials for a network using PIN and PBC methods; in
7 addition, wpa_supplicant can act as a wireless WPS Registrar to
8 configure an AP); WPS support can be enabled by adding CONFIG_WPS=y
9 into .config and setting the runtime configuration variables in
10 wpa_supplicant.conf (see WPS section in the example configuration
11 file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to
12 manage WPS negotiation; see README-WPS for more details
13 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
14 * added support for using driver_test over UDP socket
15 * fixed PEAPv0 Cryptobinding interoperability issue with Windows Server
16 2008 NPS; optional cryptobinding is now enabled (again) by default
17 * fixed PSK editing in wpa_gui
18 * changed EAP-GPSK to use the IANA assigned EAP method type 51
19 * added a Windows installer that includes WinPcap and all the needed
20 DLLs; in addition, it set up the registry automatically so that user
21 will only need start wpa_gui to get prompted to start the wpasvc
22 servide and add a new interface if needed through wpa_gui dialog
25 * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
26 (can be used to simulate test SIM/USIM card with a known private key;
27 enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
28 and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
29 * added a new network configuration option, wpa_ptk_rekey, that can be
30 used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
31 against TKIP deficiencies
32 * added an optional mitigation mechanism for certain attacks against
33 TKIP by delaying Michael MIC error reports by a random amount of time
34 between 0 and 60 seconds; this can be enabled with a build option
35 CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
36 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
38 * updated OpenSSL code for EAP-FAST to use an updated version of the
39 session ticket overriding API that was included into the upstream
40 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
41 needed with that version anymore)
42 * updated userspace MLME instructions to match with the current Linux
43 mac80211 implementation; please also note that this can only be used
44 with driver_nl80211.c (the old code from driver_wext.c was removed)
45 * added support (Linux only) for RoboSwitch chipsets (often found in
46 consumer grade routers); driver interface 'roboswitch'
47 * fixed canceling of PMKSA caching when using drivers that generate
48 RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
52 * added support for SHA-256 as X.509 certificate digest when using the
53 internal X.509/TLSv1 implementation
54 * updated management frame protection to use IEEE 802.11w/D6.0
55 * added support for using SHA256-based stronger key derivation for WPA2
57 * fixed FT (IEEE 802.11r) authentication after a failed association to
59 * added support for configuring Phase 2 (inner/tunneled) authentication
60 method with wpa_gui-qt4
63 * added support for EAP Sequences in EAP-FAST Phase 2
64 * added support for using TNC with EAP-FAST
65 * added driver_ps3 for the PS3 Linux wireless driver
66 * added support for optional cryptobinding with PEAPv0
67 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
68 allow fallback to full handshake if server rejects PAC-Opaque
69 * added fragmentation support for EAP-TNC
70 * added support for parsing PKCS #8 formatted private keys into the
71 internal TLS implementation (both PKCS #1 RSA key and PKCS #8
72 encapsulated RSA key can now be used)
73 * added option of using faster, but larger, routines in the internal
74 LibTomMath (for internal TLS implementation) to speed up DH and RSA
75 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
76 * fixed race condition between disassociation event and group key
77 handshake to avoid getting stuck in incorrect state [Bug 261]
78 * fixed opportunistic key caching (proactive_key_caching)
81 * removed 'nai' and 'eappsk' network configuration variables that were
82 previously used for configuring user identity and key for EAP-PSK,
83 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
84 replacement for 'nai' (if old configuration used a separate
85 'identity' value, that would now be configured as
86 'anonymous_identity'). 'password' field is now used as the
87 replacement for 'eappsk' (it can also be set using hexstring to
88 present random binary data)
89 * removed '-w' command line parameter (wait for interface to be added,
90 if needed); cleaner way of handling this functionality is to use an
91 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
92 when an interface is added
93 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
94 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
95 indicating when new scan results become available
96 * added new ctrl_iface command, BSS, to allow scan results to be
97 fetched without hitting the message size limits (this command
98 can be used to iterate through the scan results one BSS at the time)
99 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
100 attributes in EAP-SIM Start/Response when using fast reauthentication
101 * fixed EAPOL not to end up in infinite loop when processing dynamic
102 WEP keys with IEEE 802.1X
103 * fixed problems in getting NDIS events from WMI on Windows 2000
106 * added support for Makefile builds to include debug-log-to-a-file
107 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
108 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
109 lengths properly to avoid potential crash caused by invalid messages
110 * added data structure for storing allocated buffers (struct wpabuf);
111 this does not affect wpa_supplicant usage, but many of the APIs
112 changed and various interfaces (e.g., EAP) is not compatible with old
114 * added support for protecting EAP-AKA/Identity messages with
115 AT_CHECKCODE (optional feature in RFC 4187)
116 * added support for protected result indication with AT_RESULT_IND for
117 EAP-SIM and EAP-AKA (phase1="result_ind=1")
118 * added driver_wext workaround for race condition between scanning and
119 association with drivers that take very long time to scan all
120 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
121 using a longer hardcoded timeout for the scan if the driver supports
122 notifications for scan completion (SIOCGIWSCAN event); this helps,
123 e.g., in cases where wpa_supplicant and madwifi driver ended up in
124 loop where the driver did not even try to associate
125 * stop EAPOL timer tick when no timers are in use in order to reduce
126 power consumption (no need to wake up the process once per second)
128 * added support for privilege separation (run only minimal part of
129 wpa_supplicant functionality as root and rest as unprivileged,
130 non-root process); see 'Privilege separation' in README for details;
131 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
133 * changed scan results data structure to include all information
134 elements to make it easier to support new IEs; old get_scan_result()
135 driver_ops is still supported for backwards compatibility (results
136 are converted internally to the new format), but all drivers should
137 start using the new get_scan_results2() to make them more likely to
138 work with new features
139 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
140 application, i.e., it does not require Qt3Support anymore; Windows
141 binary of wpa_gui.exe is now from this directory and only requires
142 QtCore4.dll and QtGui4.dll libraries
143 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
144 available as a separate package to make wpa_gui installation easier:
145 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
146 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
147 only shared key/password authentication is supported in this version
150 * added support for configuring password as NtPasswordHash
151 (16-byte MD4 hash of password) in hash:<32 hex digits> format
152 * added support for fallback from abbreviated TLS handshake to
153 full handshake when using EAP-FAST (e.g., due to an expired
155 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
156 draft (draft-ietf-emu-eap-gpsk-07.txt)
157 * added support for drivers that take care of RSN 4-way handshake
158 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
159 WPA_ALG_PMK in set_key)
160 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
161 .config); this version supports only ap_scan=2 mode and allow the
162 driver to take care of the 4-way handshake
163 * fixed a buffer overflow in parsing TSF from scan results when using
164 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
166 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
167 * fixed an integer overflow issue in the ASN.1 parser used by the
168 (experimental) internal TLS implementation to avoid a potential
170 * fixed a race condition with -W option (wait for a control interface
171 monitor before starting) that could have caused the first messages to
173 * added support for processing TNCC-TNCS-Messages to report
174 recommendation (allow/none/isolate) when using TNC [Bug 243]
177 * added network configuration parameter 'frequency' for setting
178 initial channel for IBSS (adhoc) networks
179 * added experimental IEEE 802.11r/D6.0 support
180 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
181 * updated EAP-PSK to use the IANA-allocated EAP type 47
182 * fixed EAP-PAX key derivation
183 * fixed EAP-PSK bit ordering of the Flags field
184 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
185 tunnelled identity request (previously, the identifier from the outer
186 method was used, not the tunnelled identifier which could be
188 * added support for fragmentation of outer TLS packets during Phase 2
189 of EAP-PEAP/TTLS/FAST
190 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
191 * added support for EAP-FAST authentication with inner methods that
192 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
193 for PAC provisioning)
194 * added support for authenticated EAP-FAST provisioning
195 * added support for configuring maximum number of EAP-FAST PACs to
196 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
197 * added support for storing EAP-FAST PACs in binary format
198 (fast_pac_format=binary in phase1 string)
199 * fixed dbus ctrl_iface to validate message interface before
200 dispatching to avoid a possible segfault [Bug 190]
201 * fixed PeerKey key derivation to use the correct PRF label
202 * updated Windows binary build to link against OpenSSL 0.9.8d and
203 added support for EAP-FAST
204 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
205 draft (draft-ietf-emu-eap-gpsk-04.txt)
206 * fixed EAP-AKA Notification processing to allow Notification to be
207 processed after AKA Challenge response has been sent
208 * updated to use IEEE 802.11w/D2.0 for management frame protection
210 * fixed EAP-TTLS implementation not to crash on use of freed memory
211 if TLS library initialization fails
212 * added support for EAP-TNC (Trusted Network Connect)
213 (this version implements the EAP-TNC method and EAP-TTLS changes
214 needed to run two methods in sequence (IF-T) and the IF-IMC and
215 IF-TNCCS interfaces from TNCC)
218 * added experimental, integrated TLSv1 client implementation with the
219 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
220 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
221 .config); this can be useful, e.g., if the target system does not
222 have a suitable TLS library and a minimal code size is required
223 (total size of this internal TLS/crypto code is bit under 50 kB on
224 x86 and the crypto code is shared by rest of the supplicant so some
225 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
226 * removed STAKey handshake since PeerKey handshake has replaced it in
227 IEEE 802.11ma and there are no known deployments of STAKey
228 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
229 draft (draft-ietf-emu-eap-gpsk-01.txt)
230 * added preliminary implementation of IEEE 802.11w/D1.0 (management
232 (Note: this requires driver support to work properly.)
233 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
234 * fixed Windows named pipes ctrl_iface to not stop listening for
235 commands if client program opens a named pipe and closes it
236 immediately without sending a command
237 * fixed USIM PIN status determination for the case that PIN is not
238 needed (this allows EAP-AKA to be used with USIM cards that do not
240 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
241 be used with cards that do not support file selection based on
243 * added support for matching the subjectAltName of the authentication
244 server certificate against multiple name components (e.g.,
245 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
246 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
247 affects IEEE 802.1X with dynamic WEP keys)
248 * changed ctrl_iface network configuration 'get' operations to not
249 return password/key material; if these fields are requested, "*"
250 will be returned if the password/key is set, but the value of the
251 parameter is not exposed
254 * added support for building Windows version with UNICODE defined
255 (wide-char functions)
256 * driver_ndis: fixed static WEP configuration to avoid race condition
257 issues with some NDIS drivers between association and setting WEP
259 * driver_ndis: added validation for IELength value in scan results to
260 avoid crashes when using buggy NDIS drivers [Bug 165]
261 * fixed Release|Win32 target in the Visual Studio project files
262 (previously, only Debug|Win32 target was set properly)
263 * changed control interface API call wpa_ctrl_pending() to allow it to
264 return -1 on error (e.g., connection lost); control interface clients
265 will need to make sure that they verify that the value is indeed >0
266 when determining whether there are pending messages
267 * added an alternative control interface backend for Windows targets:
268 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
269 control interface mechanism for Windows builds (previously, UDP to
271 * changed ctrl_interface configuration for UNIX domain sockets:
272 - deprecated ctrl_interface_group variable (it may be removed in
274 - allow both directory and group be configured with ctrl_interface
275 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
276 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
277 case when group is not changed
278 * added support for controlling more than one interface per process in
280 * added a workaround for a case where the AP is using unknown address
281 (e.g., MAC address of the wired interface) as the source address for
282 EAPOL-Key frames; previously, that source address was used as the
283 destination for EAPOL-Key frames and in key derivation; now, BSSID is
284 used even if the source address does not match with it
285 (this resolves an interoperability issue with Thomson SpeedTouch 580)
286 * added a workaround for UDP-based control interface (which was used in
287 Windows builds before this release) to prevent packets with forged
288 addresses from being accepted as local control requests
289 * removed ndis_events.cpp and possibility of using external
290 ndis_events.exe; C version (ndis_events.c) is fully functional and
291 there is no desire to maintain two separate versions of this
293 * ndis_events: Changed NDIS event notification design to use WMI to
294 learn the adapter description through Win32_PnPEntity class; this
295 should fix some cases where the adapter name was not recognized
296 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
298 * fixed selection of the first network in ap_scan=2 mode; previously,
299 wpa_supplicant could get stuck in SCANNING state when only the first
300 network for enabled (e.g., after 'wpa_cli select_network 0')
301 * winsvc: added support for configuring ctrl_interface parameters in
302 registry (ctrl_interface string value in
303 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
304 required to enable control interface (previously, this was hardcoded
306 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
307 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
310 * fixed build with CONFIG_STAKEY=y [Bug 143]
311 * added support for doing MLME (IEEE 802.11 management frame
312 processing) in wpa_supplicant when using Devicescape IEEE 802.11
313 stack (wireless-dev.git tree)
314 * added a new network block configuration option, fragment_size, to
315 configure the maximum EAP fragment size
316 * driver_ndis: Disable WZC automatically for the selected interface to
317 avoid conflicts with two programs trying to control the radio; WZC
318 will be re-enabled (if it was enabled originally) when wpa_supplicant
320 * added an experimental TLSv1 client implementation
321 (CONFIG_TLS=internal) that can be used instead of an external TLS
322 library, e.g., to reduce total size requirement on systems that do
323 not include any TLS library by default (this is not yet complete;
324 basic functionality is there, but certificate validation is not yet
326 * added PeerKey handshake implementation for IEEE 802.11e
327 direct link setup (DLS) to replace STAKey handshake
328 * fixed WPA PSK update through ctrl_iface for the case where the old
329 PSK was derived from an ASCII passphrase and the new PSK is set as
330 a raw PSK (hex string)
331 * added new configuration option for identifying which network block
332 was used (id_str in wpa_supplicant.conf; included on
333 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
334 variable in wpa_cli action scripts; in addition WPA_ID variable is
335 set to the current unique identifier that wpa_supplicant assigned
336 automatically for the network and that can be used with
337 GET_NETWORK/SET_NETWORK ctrl_iface commands)
338 * wpa_cli action script is now called only when the connect/disconnect
339 status changes or when associating with a different network
340 * fixed configuration parser not to remove CCMP from group cipher list
341 if WPA-None (adhoc) is used (pairwise=NONE in that case)
342 * fixed integrated NDIS events processing not to hang the process due
343 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
344 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
345 draft-clancy-emu-eap-shared-secret-00.txt)
346 * added Microsoft Visual Studio 2005 solution and project files for
347 build wpa_supplicant for Windows (see vs2005 subdirectory)
348 * eloop_win: fixed unregistration of Windows events
349 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
350 at the end of RSN pre-authentication and added unregistration of
351 a Windows event to avoid getting eloop_win stuck with an invalid
353 * driver_ndis: added support for selecting AP based on BSSID
354 * added new environmental variable for wpa_cli action scripts:
355 WPA_CTRL_DIR is the current control interface directory
356 * driver_ndis: added support for using NDISUIO instead of WinPcap for
357 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
358 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
359 wpa_supplicant without requiring WinPcap; note that using NDISUIO
360 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
361 only one application to open the device
362 * changed NDIS driver naming to only include device GUID, e.g.,
363 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
364 specific \Device\NPF_ prefix before the GUID; the prefix is still
365 allowed for backwards compatibility, but it is not required anymore
366 when specifying the interface
367 * driver_ndis: re-initialize driver interface is the adapter is removed
368 and re-inserted [Bug 159]
369 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
370 big endian hosts [Bug 146]
373 * fixed EAP-GTC response to include correct user identity when run as
374 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
375 * driver_ndis: Fixed encryption mode configuration for unencrypted
376 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
377 refused to associate with open networks) [Bug 106]
378 * driver_ndis: use BSSID OID polling to detect when IBSS network is
379 formed even when ndis_events code is included since some NDIS drivers
380 do not generate media connect events in IBSS mode
381 * config_winreg: allow global ctrl_interface parameter to be configured
383 * config_winreg: added support for saving configuration data into
385 * added support for controlling network device operational state
386 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
387 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
388 that can use this information)
389 * driver_wext: added support for WE-21 change to SSID configuration
390 * driver_wext: fixed privacy configuration for static WEP keys mode
392 * added an optional driver_ops callback for MLME-SETPROTECTION.request
394 * added support for EAP-SAKE (no EAP method number allocated yet, so
395 this is using the same experimental type 255 as EAP-PSK)
396 * added support for dynamically loading EAP methods (.so files) instead
397 of requiring them to be statically linked in; this is disabled by
398 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
402 * do not try to use USIM APDUs when initializing PC/SC for SIM card
403 access for a network that has not enabled EAP-AKA
404 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
405 v0.5.1 due to the new support for expanded EAP types)
406 * added support for generating EAP Expanded Nak
407 * try to fetch scan results once before requesting new scan when
408 starting up in ap_scan=1 mode (this can speed up initial association
409 a lot with, e.g., madwifi-ng driver)
410 * added support for receiving EAPOL frames from a Linux bridge
411 interface (-bbr0 on command line)
412 * fixed EAPOL re-authentication for sessions that used PMKSA caching
413 * changed EAP method registration to use a dynamic list of methods
414 instead of a static list generated at build time
415 * fixed PMKSA cache deinitialization not to use freed memory when
416 removing PMKSA entries
417 * fixed a memory leak in EAP-TTLS re-authentication
418 * reject WPA/WPA2 message 3/4 if it does not include any valid
420 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
421 if the driver does not support SIOCSIWAUTH
424 * driver_test: added better support for multiple APs and STAs by using
425 a directory with sockets that include MAC address for each device in
426 the name (driver_param=test_dir=/tmp/test)
427 * added support for EAP expanded type (vendor specific EAP methods)
428 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
429 option can be changed if needed
430 * wpa_cli/wpa_gui: skip non-socket files in control directory when
431 using UNIX domain sockets; this avoids selecting an incorrect
432 interface (e.g., a PID file could be in this directory, even though
433 use of this directory for something else than socket files is not
435 * fixed TLS library deinitialization after RSN pre-authentication not
436 to disable TLS library for normal authentication
437 * driver_wext: Remove null-termination from SSID length if the driver
438 used it; some Linux drivers do this and they were causing problems in
439 wpa_supplicant not finding matching configuration block. This change
440 would break a case where the SSID actually ends in '\0', but that is
441 not likely to happen in real use.
442 * fixed PMKSA cache processing not to trigger deauthentication if the
443 current PMKSA cache entry is replaced with a valid new entry
444 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
445 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
448 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
449 * added experimental STAKey handshake implementation for IEEE 802.11e
450 direct link setup (DLS); note: this is disabled by default in both
451 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
453 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
454 decrypt AT_ENCR_DATA attributes correctly
455 * fixed EAP-AKA to allow resynchronization within the same session
456 * made code closer to ANSI C89 standard to make it easier to port to
457 other C libraries and compilers
458 * started moving operating system or C library specific functions into
459 wrapper functions defined in os.h and implemented in os_*.c to make
461 * wpa_supplicant can now be built with Microsoft Visual C++
462 (e.g., with the freely available Toolkit 2003 version or Visual
463 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
464 example makefile for nmake
465 * added support for using Windows registry for command line parameters
466 (CONFIG_MAIN=main_winsvc) and configuration data
467 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
468 contents; this version can be run both as a Windows service and as a
469 normal application; 'wpasvc.exe app' to start as applicant,
470 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
471 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
473 * made it possible to link ndis_events.exe functionality into
474 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
475 * added better support for multiple control interface backends
476 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
477 * fixed PC/SC code to use correct length for GSM AUTH command buffer
478 and to not use pioRecvPci with SCardTransmit() calls; these were not
479 causing visible problems with pcsc-lite, but Windows Winscard.dll
480 refused the previously used parameters; this fixes EAP-SIM and
481 EAP-AKA authentication using SIM/USIM card under Windows
482 * added new event loop implementation for Windows using
483 WaitForMultipleObject() instead of select() in order to allow waiting
484 for non-socket objects; this can be selected with
485 CONFIG_ELOOP=eloop_win in .config
486 * added support for selecting l2_packet implementation in .config
487 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
488 winpcap, freebsd, none)
489 * added new l2_packet implementation for WinPcap
490 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
491 reduce latency in EAPOL receive processing from about 100 ms to about
493 * added support for EAP-FAST key derivation using other ciphers than
494 RC4-128-SHA for authentication and AES128-SHA for provisioning
495 * added support for configuring CA certificate as DER file and as a
497 * fixed private key configuration as configuration blob and added
498 support for using PKCS#12 as a blob
499 * tls_gnutls: added support for using PKCS#12 files; added support for
501 * added support for loading trusted CA certificates from Windows
502 certificate store: ca_cert="cert_store://<name>", where <name> is
503 likely CA (Intermediate CA certificates) or ROOT (root certificates)
504 * added C version of ndis_events.cpp and made it possible to build this
505 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
506 easily on cross-compilation builds
507 * added wpasvc.exe into Windows binary release; this is an alternative
508 version of wpa_supplicant.exe with configuration backend using
509 Windows registry and with the entry point designed to run as a
511 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
512 wpasvc.exe and removed this additional tool from the Windows binary
513 release since it is not needed anymore
514 * load winscard.dll functions dynamically when building with MinGW
515 since MinGW does not yet include winscard library
517 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
518 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
519 and WinPcap to receive frames sent to PAE group address
520 * disable EAP state machine when IEEE 802.1X authentication is not used
521 in order to get rid of bogus "EAP failed" messages
522 * fixed OpenSSL error reporting to go through all pending errors to
523 avoid confusing reports of old errors being reported at later point
525 * fixed configuration file updating to not write empty variables
526 (e.g., proto or key_mgmt) that the file parser would not accept
527 * fixed ADD_NETWORK ctrl_iface command to use the same default values
528 for variables as empty network definitions read from config file
530 * fixed EAP state machine to not discard EAP-Failure messages in many
531 cases (e.g., during TLS handshake)
532 * fixed a infinite loop in private key reading if the configured file
533 cannot be parsed successfully
534 * driver_madwifi: added support for madwifi-ng
535 * wpa_gui: do not display password/PSK field contents
536 * wpa_gui: added CA certificate configuration
537 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
538 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
539 the new AP is using different WPA/RSN IE
540 * use longer timeout for IEEE 802.11 association to avoid problems with
541 drivers that may take more than five second to associate
544 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
545 RSN IE, but WPA IE would match with wpa_supplicant configuration
546 * added support for named configuration blobs in order to avoid having
547 to use file system for external files (e.g., certificates);
548 variables can be set to "blob://<blob name>" instead of file path to
549 use a named blob; supported fields: pac_file, client_cert,
551 * fixed RSN pre-authentication (it was broken in the clean up of WPA
552 state machine interface in v0.4.5)
553 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
554 sure the driver configures broadcast decryption correctly
555 * added ca_path (and ca_path2) configuration variables that can be used
556 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
557 system-wide trusted CA list
558 * added support for starting wpa_supplicant without a configuration
559 file (-C argument must be used to set ctrl_interface parameter for
560 this case; in addition, -p argument can be used to provide
561 driver_param; these new arguments can also be used with a
562 configuration to override the values from the configuration)
563 * added global control interface that can be optionally used for adding
564 and removing network interfaces dynamically (-g command line argument
565 for both wpa_supplicant and wpa_cli) without having to restart
566 wpa_supplicant process
568 - try to save configuration whenever something is modified
569 - added WEP key configuration
570 - added possibility to edit the current network configuration
571 * driver_ndis: fixed driver polling not to increase frequency on each
572 received EAPOL frame due to incorrectly cancelled timeout
573 * added simple configuration file examples (in examples subdirectory)
574 * fixed driver_wext.c to filter wireless events based on ifindex to
575 avoid interfaces receiving events from other interfaces
576 * delay sending initial EAPOL-Start couple of seconds to speed up
577 authentication for the most common case of Authenticator starting
578 EAP authentication immediately after association
581 * added a workaround for clearing keys with ndiswrapper to allow
582 roaming from WPA enabled AP to plaintext one
583 * added docbook documentation (doc/docbook) that can be used to
584 generate, e.g., man pages
585 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
586 PF_PACKET in order to prepare for network devices that do not use
587 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
588 * use receipt of EAPOL-Key frame as a lower layer success indication
589 for EAP state machine to allow recovery from dropped EAP-Success
591 * cleaned up internal EAPOL frame processing by not including link
592 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
593 header is added only when transmitted the frame; this makes it easier
594 to use wpa_supplicant on link layers that use different header than
596 * updated EAP-PSK to use draft 9 by default since this can now be
597 tested with hostapd; removed support for draft 3, including
598 server_nai configuration option from network blocks
599 * driver_wired: add PAE address to the multicast address list in order
600 to be able to receive EAPOL frames with drivers that do not include
601 these multicast addresses by default
602 * driver_wext: add support for WE-19
603 * added support for multiple configuration backends (CONFIG_BACKEND
604 option); currently, only 'file' is supported (i.e., the format used
605 in wpa_supplicant.conf)
606 * added support for updating configuration ('wpa_cli save_config');
607 this is disabled by default and can be enabled with global
608 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
609 and wpa_gui to store the configuration changes in a permanent store
610 * added GET_NETWORK ctrl_iface command
611 (e.g., 'wpa_cli get_network 0 ssid')
614 * replaced OpenSSL patch for EAP-FAST support
615 (openssl-tls-extensions.patch) with a more generic and correct
616 patch (the new patch is not compatible with the previous one, so the
617 OpenSSL library will need to be patched with the new patch in order
618 to be able to build wpa_supplicant with EAP-FAST support)
619 * added support for using Windows certificate store (through CryptoAPI)
620 for client certificate and private key operations (EAP-TLS)
621 (see wpa_supplicant.conf for more information on how to configure
622 this with private_key)
623 * ported wpa_gui to Windows
624 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
625 built with the open source version of the Qt4 for Windows
626 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
627 with drivers that do not support WPA
628 * ndis_events: fixed Windows 2000 support
629 * added support for enabling/disabling networks from the list of all
630 configured networks ('wpa_cli enable_network <network id>' and
631 'wpa_cli disable_network <network id>')
632 * added support for adding and removing network from the current
633 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
634 <network id>'); added networks are disabled by default and they can
635 be enabled with enable_network command once the configuration is done
636 for the new network; note: configuration file is not yet updated, so
637 these new networks are lost when wpa_supplicant is restarted
638 * added support for setting network configuration parameters through
639 the control interface, for example:
640 wpa_cli set_network 0 ssid "\"my network\""
641 * fixed parsing of strings that include both " and # within double
642 quoted area (e.g., "start"#end")
643 * added EAP workaround for PEAP session resumption: allow outer,
644 i.e., not tunneled, EAP-Success to terminate session since; this can
645 be disabled with eap_workaround=0
646 (this was allowed for PEAPv1 before, but now it is also allowed for
647 PEAPv0 since at least one RADIUS authentication server seems to be
648 doing this for PEAPv0, too)
649 * wpa_gui: added preliminary support for adding new networks to the
650 wpa_supplicant configuration (double click on the scan results to
651 open network configuration)
654 * removed interface for external EAPOL/EAP supplicant (e.g.,
655 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
656 anymore and is unlikely to be used by anyone
657 * driver_ndis: fixed WinPcap 3.0 support
658 * fixed build with CONFIG_DNET_PCAP=y on Linux
659 * l2_packet: moved different implementations into separate files
663 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
664 (note: ipw2100-1.1.0 is likely to require an update to work with
666 * added support for using ap_scan=2 mode with multiple network blocks;
667 wpa_supplicant will go through the networks one by one until the
668 driver reports a successful association; this uses the same order for
669 networks as scan_ssid=1 scans, i.e., the priority field is ignored
670 and the network block order in the file is used instead
671 * fixed a potential issue in RSN pre-authentication ending up using
672 freed memory if pre-authentication times out
673 * added support for matching alternative subject name extensions of the
674 authentication server certificate; new configuration variables
675 altsubject_match and altsubject_match2
676 * driver_ndis: added support for IEEE 802.1X authentication with wired
678 * added support for querying private key password (EAP-TLS) through the
679 control interface (wpa_cli/wpa_gui) if one is not included in the
681 * driver_broadcom: fixed couple of memory leaks in scan result
683 * EAP-PAX is now registered as EAP type 46
684 * fixed EAP-PAX MAC calculation
685 * fixed EAP-PAX CK and ICK key derivation
686 * added support for using password with EAP-PAX (as an alternative to
687 entering key with eappsk); SHA-1 hash of the password will be used as
689 * added support for arbitrary driver interface parameters through the
690 configuration file with a new driver_param field; this adds a new
691 driver_ops function set_param()
692 * added possibility to override l2_packet module with driver interface
693 API (new send_eapol handler); this can be used to implement driver
694 specific TX/RX functions for EAPOL frames
695 * fixed ctrl_interface_group processing for the case where gid is
696 entered as a number, not group name
697 * driver_test: added support for testing hostapd with wpa_supplicant
698 by using test driver interface without any kernel drivers or network
702 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
703 packets to be encrypted; this was apparently broken by the changed
704 ioctl order in v0.4.0
705 * driver_madwifi: added preliminary support for compiling against 'BSD'
706 branch of madwifi CVS tree
707 * added support for EAP-MSCHAPv2 password retries within the same EAP
708 authentication session
709 * added support for password changes with EAP-MSCHAPv2 (used when the
710 password has expired)
711 * added support for reading additional certificates from PKCS#12 files
712 and adding them to the certificate chain
713 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
715 * fixed a possible double free in EAP-TTLS fast-reauthentication when
716 identity or password is entered through control interface
717 * display EAP Notification messages to user through control interface
718 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
719 * added GUI version of wpa_cli, wpa_gui; this is not build
720 automatically with 'make'; use 'make wpa_gui' to build (this requires
721 Qt development tools)
722 * added 'disconnect' command to control interface for setting
723 wpa_supplicant in state where it will not associate before
724 'reassociate' command has been used
725 * added support for selecting a network from the list of all configured
726 networks ('wpa_cli select_network <network id>'; this disabled all
727 other networks; to re-enable, 'wpa_cli select_network any')
728 * added support for getting scan results through control interface
729 * added EAP workaround for PEAPv1 session resumption: allow outer,
730 i.e., not tunneled, EAP-Success to terminate session since; this can
731 be disabled with eap_workaround=0
733 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
734 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
735 used to reduce the size of the wpa_supplicant considerably if
736 debugging code is not needed
737 * fixed EAPOL-Key validation to drop packets with invalid Key Data
738 Length; such frames could have crashed wpa_supplicant due to buffer
740 * added support for wired authentication (IEEE 802.1X on wired
741 Ethernet); driver interface 'wired'
742 * obsoleted set_wpa() handler in the driver interface API (it can be
743 replaced by moving enable/disable functionality into init()/deinit())
744 (calls to set_wpa() are still present for backwards compatibility,
745 but they may be removed in the future)
746 * driver_madwifi: fixed association in plaintext mode
747 * modified the EAP workaround that accepts EAP-Success with incorrect
748 Identifier to be even less strict about verification in order to
749 interoperate with some authentication servers
750 * added support for sending TLS alerts
751 * added support for 'any' SSID wildcard; if ssid is not configured or
752 is set to an empty string, any SSID will be accepted for non-WPA AP
753 * added support for asking PIN (for SIM) from frontends (e.g.,
754 wpa_cli); if a PIN is needed, but not included in the configuration
755 file, a control interface request is sent and EAP processing is
756 delayed until the PIN is available
757 * added support for using external devices (e.g., a smartcard) for
758 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
759 new wpa_supplicant.conf variables:
760 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
761 - network: engine, engine_id, key_id
762 * added experimental support for EAP-PAX
763 * added monitor mode for wpa_cli (-a<path to a program to run>) that
764 allows external commands (e.g., shell scripts) to be run based on
765 wpa_supplicant events, e.g., when authentication has been completed
766 and data connection is ready; other related wpa_cli arguments:
767 -B (run in background), -P (write PID file); wpa_supplicant has a new
768 command line argument (-W) that can be used to make it wait until a
769 control interface command is received in order to avoid missing
771 * added support for opportunistic WPA2 PMKSA key caching (disabled by
772 default, can be enabled with proactive_key_caching=1)
773 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
774 Authenticator rejects PMKSA caching attempt and the driver is not
775 using assoc_info events
776 * added -P<pid file> argument for wpa_supplicant to write the current
777 process id into a file
779 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
780 * added new phase1 option parameter, include_tls_length=1, to force
781 wpa_supplicant to add TLS Message Length field to all TLS messages
782 even if the packet is not fragmented; this may be needed with some
783 authentication servers
784 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
785 using drivers that take care of AP selection (e.g., when using
787 * fixed reprocessing of pending request after ctrl_iface requests for
788 identity/password/otp
789 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
790 EAP-PEAP and EAP-TTLS
791 * all drivers using driver_wext: set interface up and select Managed
792 mode when starting wpa_supplicant; set interface down when exiting
793 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
794 ipw2100 and ipw2200; please note that this also changed the
795 configuration variable in .config to CONFIG_DRIVER_IPW
798 * fixed a busy loop introduced in v0.3.5 for scan result processing
799 when no matching AP is found
802 * added a workaround for an interoperability issue with a Cisco AP
804 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
805 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
806 retransmission of dropped frames)
807 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
808 (e.g., segfault when processing EAPOL-Key frames)
809 * fixed EAP workaround and fast reauthentication configuration for
810 RSN pre-authentication; previously these were disabled and
811 pre-authentication would fail if the used authentication server
812 requires EAP workarounds
813 * added support for blacklisting APs that fail or timeout
814 authentication in ap_scan=1 mode so that all APs are tried in cases
815 where the ones with strongest signal level are failing authentication
816 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
817 authentication attempt
818 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
819 in the previous authentication (previously, only Phase 1 success was
823 * added preliminary support for IBSS (ad-hoc) mode configuration
824 (mode=1 in network block); this included a new key_mgmt mode
825 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
826 key management; see wpa_supplicant.conf for more details and an
827 example on how to configure this (note: this is currently implemented
828 only for driver_hostapd.c, but the changes should be trivial to add
829 in associate() handler for other drivers, too (assuming the driver
831 * added preliminary port for native Windows (i.e., no cygwin) using
835 * added optional support for GNU Readline and History Libraries for
836 wpa_cli (CONFIG_READLINE)
837 * cleaned up EAP state machine <-> method interface and number of
838 small problems with error case processing not terminating on
839 EAP-Failure but waiting for timeout
840 * added couple of workarounds for interoperability issues with a
841 Cisco AP when using WPA2
842 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
843 Note: This requires a patch for openssl to add support for TLS
844 extensions and number of workarounds for operations without
845 certificates. Proof of concept type of experimental patch is
846 included in openssl-tls-extensions.patch.
849 * fixed private key loading for cases where passphrase is not set
850 * fixed Windows/cygwin L2 packet handler freeing; previous version
851 could cause a segfault when RSN pre-authentication was completed
852 * added support for PMKSA caching with drivers that generate RSN IEs
853 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
854 but similar code can be easily added to driver_ndiswrapper.c once
855 ndiswrapper gets full support for RSN PMKSA caching
856 * improved recovery from PMKID mismatches by requesting full EAP
857 authentication in case of failed PMKSA caching attempt
858 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
859 (this requires that ndis_events is ran while wpa_supplicant is
861 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
862 * added support for driver interfaces to replace the interface name
863 based on driver/OS specific mapping, e.g., in case of driver_ndis,
864 this allows the beginning of the adapter description to be used as
866 * added support for CR+LF (Windows-style) line ends in configuration
868 * driver_ndis: enable radio before starting scanning, disable radio
870 * modified association event handler to set portEnabled = FALSE before
871 clearing port Valid in order to reset EAP state machine and avoid
872 problems with new authentication getting ignored because of state
873 machines ending up in AUTHENTICATED/SUCCESS state based on old
875 * added support for driver events to add PMKID candidates in order to
876 allow drivers to give priority to most likely roaming candidates
877 * driver_hostap: moved PrivacyInvoked configuration to associate()
878 function so that this will not be set for plaintext connections
879 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
880 interface can distinguish plaintext and IEEE 802.1X (no WPA)
882 * fixed static WEP key configuration to use broadcast/default type for
883 all keys (previously, the default TX key was configured as pairwise/
885 * driver_ndis: added legacy WPA capability detection for non-WPA2
887 * added support for setting static WEP keys for IEEE 802.1X without
888 dynamic WEP keying (eapol_flags=0)
891 * added support for reading PKCS#12 (PFX) files (as a replacement for
892 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
893 * fixed compilation with CONFIG_PCSC=y
894 * added new ap_scan mode, ap_scan=2, for drivers that take care of
895 association, but need to be configured with security policy and SSID,
896 e.g., ndiswrapper and NDIS driver; this mode should allow such
897 drivers to work with hidden SSIDs and optimized roaming; when
898 ap_scan=2 is used, only the first network block in the configuration
899 file is used and this configuration should have explicit security
900 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
901 group, proto variables
902 * added experimental port of wpa_supplicant for Windows
903 - driver_ndis.c driver interface (NDIS OIDs)
904 - currently, this requires cygwin and WinPcap
905 - small utility, win_if_list, can be used to get interface name
906 * control interface can now be removed at build time; add
907 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
908 * optional Xsupplicant interface can now be removed at build time;
909 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
910 * added auth_alg to driver interface associate() parameters to make it
911 easier for drivers to configure authentication algorithm as part of
914 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
915 * driver_broadcom: added new driver interface for Broadcom wl.o driver
916 (a generic driver for Broadcom IEEE 802.11a/g cards)
917 * wpa_cli: fixed parsing of -p <path> command line argument
918 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
919 ACK, not tunneled EAP-Success (of which only the first byte was
920 actually send due to a bug in previous code); this seems to
921 interoperate with most RADIUS servers that implements PEAPv1
922 * PEAPv1: added support for terminating PEAP authentication on tunneled
923 EAP-Success message; this can be configured by adding
924 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
925 (some RADIUS servers require this whereas others require a tunneled
927 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
928 the old label for key derivation; previously, the default was 1,
929 but it looks like most existing PEAPv1 implementations use the old
930 label which is thus more suitable default option
931 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
932 * fixed parsing of wep_tx_keyidx
933 * added support for configuring list of allowed Phase 2 EAP types
934 (for both EAP-PEAP and EAP-TTLS) instead of only one type
935 * added support for configuring IEEE 802.11 authentication algorithm
936 (auth_alg; mainly for using Shared Key authentication with static
938 * added support for EAP-AKA (with UMTS SIM)
939 * fixed couple of errors in PCSC handling that could have caused
940 random-looking errors for EAP-SIM
941 * added support for EAP-SIM pseudonyms and fast re-authentication
942 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
944 * added support for EAP-SIM with two challanges
945 (phase1="sim_min_num_chal=3" can be used to require three challenges)
946 * added support for configuring DH/DSA parameters for an ephemeral DH
947 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
948 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
949 and optional DH key exchange to achieve forward secracy with RSA keys
950 * added support for matching subject of the authentication server
951 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
952 configuration variables subject_match and subject_match2
953 * changed SSID configuration in driver_wext.c (used by many driver
954 interfaces) to use ssid_len+1 as the length for SSID since some Linux
956 * fixed couple of unaligned reads in scan result parsing to fix WPA
957 connection on some platforms (e.g., ARM)
958 * added driver interface for Intel ipw2100 driver
959 * added support for LEAP with WPA
960 * added support for larger scan results report (old limit was 4 kB of
961 data, i.e., about 35 or so APs) when using Linux wireless extensions
963 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
964 only if there is a PMKSA cache entry for the current AP
965 * fixed error handling for case where reading of scan results fails:
966 must schedule a new scan or wpa_supplicant will remain waiting
968 * changed debug output to remove shared password/key material by
969 default; all key information can be included with -K command line
970 argument to match the previous behavior
971 * added support for timestamping debug log messages (disabled by
972 default, can be enabled with -t command line argument)
973 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
974 if keys are not configured to be used; this fixes IEEE 802.1X mode
975 with drivers that use this information to configure whether Privacy
976 bit can be in Beacon frames (e.g., ndiswrapper)
977 * avoid clearing driver keys if no keys have been configured since last
978 key clear request; this seems to improve reliability of group key
979 handshake for ndiswrapper & NDIS driver which seems to be suffering
980 of some kind of timing issue when the keys are cleared again after
982 * changed driver interface API:
983 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
984 version is being used (now, this is set to 2; previously, it was
986 - pass pointer to private data structure to all calls
987 - the new API is not backwards compatible; all in-tree driver
988 interfaces has been converted to the new API
989 * added support for controlling multiple interfaces (radios) per
990 wpa_supplicant process; each interface needs to be listed on the
991 command line (-c, -i, -D arguments) with -N as a separator
992 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
993 * added a workaround for EAP servers that incorrectly use same Id for
994 sequential EAP packets
995 * changed libpcap/libdnet configuration to use .config variable,
996 CONFIG_DNET_PCAP, instead of requiring Makefile modification
997 * improved downgrade attack detection in IE verification of msg 3/4:
998 verify both WPA and RSN IEs, if present, not only the selected one;
999 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
1000 Probe Response frame, and RSN is enabled in wpa_supplicant
1002 * fixed WPA msg 3/4 processing to allow Key Data field contain other
1003 IEs than just one WPA IE
1004 * added support for FreeBSD and driver interface for the BSD net80211
1005 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
1006 required kernel mods have not yet been committed
1007 * made EAP workarounds configurable; enabled by default, can be
1008 disabled with network block option eap_workaround=0
1010 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
1011 * resolved couple of interoperability issues with EAP-PEAPv1 and
1012 Phase 2 (inner EAP) fragment reassembly
1013 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
1014 AP is using non-zero key index for the unicast key and key index zero
1015 for the broadcast key
1016 * driver_hostap: fixed IEEE 802.1X WEP key updates and
1017 re-authentication by allowing unencrypted EAPOL frames when not using
1019 * added a new driver interface, 'wext', which uses only standard,
1020 driver independent functionality in Linux wireless extensions;
1021 currently, this can be used only for non-WPA IEEE 802.1X mode, but
1022 eventually, this is to be extended to support full WPA/WPA2 once
1023 Linux wireless extensions get support for this
1024 * added support for mode in which the driver is responsible for AP
1025 scanning and selection; this is disabled by default and can be
1026 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
1027 this mode can be used, e.g., with generic 'wext' driver interface to
1028 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
1029 supporting wireless extensions.
1030 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
1031 operation with an AP that does not include SSID in the Beacon frames)
1032 * added support for new EAP authentication methods:
1033 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
1034 * added support for asking one-time-passwords from frontends (e.g.,
1035 wpa_cli); this 'otp' command works otherwise like 'password' command,
1036 but the password is used only once and the frontend will be asked for
1037 a new password whenever a request from authenticator requires a
1038 password; this can be used with both EAP-OTP and EAP-GTC
1039 * changed wpa_cli to automatically re-establish connection so that it
1040 does not need to be re-started when wpa_supplicant is terminated and
1042 * improved user data (identity/password/otp) requests through
1043 frontends: process pending EAPOL packets after getting new
1044 information so that full authentication does not need to be
1045 restarted; in addition, send pending requests again whenever a new
1046 frontend is attached
1047 * changed control frontends to use a new directory for socket files to
1048 make it easier for wpa_cli to automatically select between interfaces
1049 and to provide access control for the control interface;
1050 wpa_supplicant.conf: ctrl_interface is now a path
1051 (/var/run/wpa_supplicant is the recommended path) and
1052 ctrl_interface_group can be used to select which group gets access to
1053 the control interface;
1054 wpa_cli: by default, try to connect to the first interface available
1055 in /var/run/wpa_supplicant; this path can be overriden with -p option
1056 and an interface can be selected with -i option (i.e., in most common
1057 cases, wpa_cli does not need to get any arguments)
1058 * added support for LEAP
1059 * added driver interface for Linux ndiswrapper
1060 * added priority option for network blocks in the configuration file;
1061 this allows networks to be grouped based on priority (the scan
1062 results are searched for matches with network blocks in this order)
1065 * sort scan results to improve AP selection
1066 * fixed control interface socket removal for some error cases
1067 * improved scan requesting and authentication timeout
1068 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1070 * PEAP version can now be forced with phase1="peapver=<ver>"
1071 (mostly for testing; by default, the highest version supported by
1072 both the Supplicant and Authentication Server is selected
1074 * added support for madwifi driver (Atheros ar521x)
1075 * added a workaround for cases where AP sets Install Tx/Rx bit for
1076 WPA Group Key messages when pairwise keys are used (without this,
1077 the Group Key would be used for Tx and the AP would drop frames
1079 * added GSM SIM/USIM interface for GSM authentication algorithm for
1080 EAP-SIM; this requires pcsc-lite
1081 * added support for ATMEL AT76C5XXx driver
1082 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1083 does not include key data in the EAPOL-Key frame (i.e., part of
1084 EAP keying material is used as data encryption key)
1085 * added support for using plaintext and static WEP networks
1089 * added support for new EAP authentication methods:
1090 EAP-TTLS/EAP-MD5-Challenge
1092 EAP-TTLS/EAP-MSCHAPv2
1100 EAP-PEAP/MD5-Challenge
1102 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1103 * added support for anonymous identity (to be used when identity is
1104 sent in plaintext; real identity will be used within TLS protected
1105 tunnel (e.g., with EAP-TTLS)
1106 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1107 * added support for requesting identity and password information using
1108 control interface; in other words, the password for EAP-PEAP or
1109 EAP-TTLS does not need to be included in the configuration file since
1110 a frontand (e.g., wpa_cli) can ask it from the user
1111 * improved RSN pre-authentication to use a candidate list and process
1112 all candidates from each scan; not only one per scan
1113 * fixed RSN IE and WPA IE capabilities field parsing
1114 * ignore Tx bit in GTK IE when Pairwise keys are used
1115 * avoid making new scan requests during IEEE 802.1X negotiation
1116 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1117 with TLS support (this replaces the included implementation with
1118 library code to save about 8 kB since the library code is needed
1120 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1121 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1124 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1126 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1127 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1128 - EAP-MD5 (cannot be used with WPA-RADIUS)
1129 [draft-ietf-eap-rfc2284bis-09.txt]
1130 - EAP-TLS [RFC 2716]
1131 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1132 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1133 [draft-kamath-pppext-eap-mschapv2-00.txt]
1134 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1135 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1136 - new configuration file options: eap, identity, password, ca_cert,
1137 client_cert, privatekey, private_key_passwd
1138 - Xsupplicant is not required anymore, but it can be used by
1139 disabling the internal IEEE 802.1X Supplicant with -e command line
1141 - this code is not included in the default build; Makefile need to
1142 be edited for this (uncomment lines for selected functionality)
1143 - EAP-TLS and EAP-PEAP require openssl libraries
1144 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1145 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1146 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1147 EAPOL-Key frames instead of WPA key handshakes)
1148 * added support for IEEE 802.11i/RSN (WPA2)
1149 - improved PTK Key Handshake
1150 - PMKSA caching, pre-authentication
1151 * fixed wpa_supplicant to ignore possible extra data after WPA
1152 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1153 TPTK' error from message 3 of 4-Way Handshake in case the AP
1154 includes extra data after the EAPOL-Key)
1155 * added interface for external programs (frontends) to control
1157 - CLI example (wpa_cli) with interactive mode and command line
1159 - replaced SIGUSR1 status/statistics with the new control interface
1160 * made some feature compile time configurable
1161 - .config file for make
1162 - driver interfaces (hostap, hermes, ..)
1163 - EAPOL/EAP functions
1166 * Initial version of wpa_supplicant
