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
20 * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
21 (can be used to simulate test SIM/USIM card with a known private key;
22 enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
23 and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
24 * added a new network configuration option, wpa_ptk_rekey, that can be
25 used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
26 against TKIP deficiencies
27 * added an optional mitigation mechanism for certain attacks against
28 TKIP by delaying Michael MIC error reports by a random amount of time
29 between 0 and 60 seconds; this can be enabled with a build option
30 CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
31 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
33 * updated OpenSSL code for EAP-FAST to use an updated version of the
34 session ticket overriding API that was included into the upstream
35 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
36 needed with that version anymore)
37 * updated userspace MLME instructions to match with the current Linux
38 mac80211 implementation; please also note that this can only be used
39 with driver_nl80211.c (the old code from driver_wext.c was removed)
40 * added support (Linux only) for RoboSwitch chipsets (often found in
41 consumer grade routers); driver interface 'roboswitch'
42 * fixed canceling of PMKSA caching when using drivers that generate
43 RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
47 * added support for SHA-256 as X.509 certificate digest when using the
48 internal X.509/TLSv1 implementation
49 * updated management frame protection to use IEEE 802.11w/D6.0
50 * added support for using SHA256-based stronger key derivation for WPA2
52 * fixed FT (IEEE 802.11r) authentication after a failed association to
54 * added support for configuring Phase 2 (inner/tunneled) authentication
55 method with wpa_gui-qt4
58 * added support for EAP Sequences in EAP-FAST Phase 2
59 * added support for using TNC with EAP-FAST
60 * added driver_ps3 for the PS3 Linux wireless driver
61 * added support for optional cryptobinding with PEAPv0
62 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
63 allow fallback to full handshake if server rejects PAC-Opaque
64 * added fragmentation support for EAP-TNC
65 * added support for parsing PKCS #8 formatted private keys into the
66 internal TLS implementation (both PKCS #1 RSA key and PKCS #8
67 encapsulated RSA key can now be used)
68 * added option of using faster, but larger, routines in the internal
69 LibTomMath (for internal TLS implementation) to speed up DH and RSA
70 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
71 * fixed race condition between disassociation event and group key
72 handshake to avoid getting stuck in incorrect state [Bug 261]
73 * fixed opportunistic key caching (proactive_key_caching)
76 * removed 'nai' and 'eappsk' network configuration variables that were
77 previously used for configuring user identity and key for EAP-PSK,
78 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
79 replacement for 'nai' (if old configuration used a separate
80 'identity' value, that would now be configured as
81 'anonymous_identity'). 'password' field is now used as the
82 replacement for 'eappsk' (it can also be set using hexstring to
83 present random binary data)
84 * removed '-w' command line parameter (wait for interface to be added,
85 if needed); cleaner way of handling this functionality is to use an
86 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
87 when an interface is added
88 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
89 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
90 indicating when new scan results become available
91 * added new ctrl_iface command, BSS, to allow scan results to be
92 fetched without hitting the message size limits (this command
93 can be used to iterate through the scan results one BSS at the time)
94 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
95 attributes in EAP-SIM Start/Response when using fast reauthentication
96 * fixed EAPOL not to end up in infinite loop when processing dynamic
97 WEP keys with IEEE 802.1X
98 * fixed problems in getting NDIS events from WMI on Windows 2000
101 * added support for Makefile builds to include debug-log-to-a-file
102 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
103 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
104 lengths properly to avoid potential crash caused by invalid messages
105 * added data structure for storing allocated buffers (struct wpabuf);
106 this does not affect wpa_supplicant usage, but many of the APIs
107 changed and various interfaces (e.g., EAP) is not compatible with old
109 * added support for protecting EAP-AKA/Identity messages with
110 AT_CHECKCODE (optional feature in RFC 4187)
111 * added support for protected result indication with AT_RESULT_IND for
112 EAP-SIM and EAP-AKA (phase1="result_ind=1")
113 * added driver_wext workaround for race condition between scanning and
114 association with drivers that take very long time to scan all
115 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
116 using a longer hardcoded timeout for the scan if the driver supports
117 notifications for scan completion (SIOCGIWSCAN event); this helps,
118 e.g., in cases where wpa_supplicant and madwifi driver ended up in
119 loop where the driver did not even try to associate
120 * stop EAPOL timer tick when no timers are in use in order to reduce
121 power consumption (no need to wake up the process once per second)
123 * added support for privilege separation (run only minimal part of
124 wpa_supplicant functionality as root and rest as unprivileged,
125 non-root process); see 'Privilege separation' in README for details;
126 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
128 * changed scan results data structure to include all information
129 elements to make it easier to support new IEs; old get_scan_result()
130 driver_ops is still supported for backwards compatibility (results
131 are converted internally to the new format), but all drivers should
132 start using the new get_scan_results2() to make them more likely to
133 work with new features
134 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
135 application, i.e., it does not require Qt3Support anymore; Windows
136 binary of wpa_gui.exe is now from this directory and only requires
137 QtCore4.dll and QtGui4.dll libraries
138 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
139 available as a separate package to make wpa_gui installation easier:
140 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
141 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
142 only shared key/password authentication is supported in this version
145 * added support for configuring password as NtPasswordHash
146 (16-byte MD4 hash of password) in hash:<32 hex digits> format
147 * added support for fallback from abbreviated TLS handshake to
148 full handshake when using EAP-FAST (e.g., due to an expired
150 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
151 draft (draft-ietf-emu-eap-gpsk-07.txt)
152 * added support for drivers that take care of RSN 4-way handshake
153 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
154 WPA_ALG_PMK in set_key)
155 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
156 .config); this version supports only ap_scan=2 mode and allow the
157 driver to take care of the 4-way handshake
158 * fixed a buffer overflow in parsing TSF from scan results when using
159 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
161 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
162 * fixed an integer overflow issue in the ASN.1 parser used by the
163 (experimental) internal TLS implementation to avoid a potential
165 * fixed a race condition with -W option (wait for a control interface
166 monitor before starting) that could have caused the first messages to
168 * added support for processing TNCC-TNCS-Messages to report
169 recommendation (allow/none/isolate) when using TNC [Bug 243]
172 * added network configuration parameter 'frequency' for setting
173 initial channel for IBSS (adhoc) networks
174 * added experimental IEEE 802.11r/D6.0 support
175 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
176 * updated EAP-PSK to use the IANA-allocated EAP type 47
177 * fixed EAP-PAX key derivation
178 * fixed EAP-PSK bit ordering of the Flags field
179 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
180 tunnelled identity request (previously, the identifier from the outer
181 method was used, not the tunnelled identifier which could be
183 * added support for fragmentation of outer TLS packets during Phase 2
184 of EAP-PEAP/TTLS/FAST
185 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
186 * added support for EAP-FAST authentication with inner methods that
187 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
188 for PAC provisioning)
189 * added support for authenticated EAP-FAST provisioning
190 * added support for configuring maximum number of EAP-FAST PACs to
191 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
192 * added support for storing EAP-FAST PACs in binary format
193 (fast_pac_format=binary in phase1 string)
194 * fixed dbus ctrl_iface to validate message interface before
195 dispatching to avoid a possible segfault [Bug 190]
196 * fixed PeerKey key derivation to use the correct PRF label
197 * updated Windows binary build to link against OpenSSL 0.9.8d and
198 added support for EAP-FAST
199 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
200 draft (draft-ietf-emu-eap-gpsk-04.txt)
201 * fixed EAP-AKA Notification processing to allow Notification to be
202 processed after AKA Challenge response has been sent
203 * updated to use IEEE 802.11w/D2.0 for management frame protection
205 * fixed EAP-TTLS implementation not to crash on use of freed memory
206 if TLS library initialization fails
207 * added support for EAP-TNC (Trusted Network Connect)
208 (this version implements the EAP-TNC method and EAP-TTLS changes
209 needed to run two methods in sequence (IF-T) and the IF-IMC and
210 IF-TNCCS interfaces from TNCC)
213 * added experimental, integrated TLSv1 client implementation with the
214 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
215 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
216 .config); this can be useful, e.g., if the target system does not
217 have a suitable TLS library and a minimal code size is required
218 (total size of this internal TLS/crypto code is bit under 50 kB on
219 x86 and the crypto code is shared by rest of the supplicant so some
220 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
221 * removed STAKey handshake since PeerKey handshake has replaced it in
222 IEEE 802.11ma and there are no known deployments of STAKey
223 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
224 draft (draft-ietf-emu-eap-gpsk-01.txt)
225 * added preliminary implementation of IEEE 802.11w/D1.0 (management
227 (Note: this requires driver support to work properly.)
228 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
229 * fixed Windows named pipes ctrl_iface to not stop listening for
230 commands if client program opens a named pipe and closes it
231 immediately without sending a command
232 * fixed USIM PIN status determination for the case that PIN is not
233 needed (this allows EAP-AKA to be used with USIM cards that do not
235 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
236 be used with cards that do not support file selection based on
238 * added support for matching the subjectAltName of the authentication
239 server certificate against multiple name components (e.g.,
240 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
241 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
242 affects IEEE 802.1X with dynamic WEP keys)
243 * changed ctrl_iface network configuration 'get' operations to not
244 return password/key material; if these fields are requested, "*"
245 will be returned if the password/key is set, but the value of the
246 parameter is not exposed
249 * added support for building Windows version with UNICODE defined
250 (wide-char functions)
251 * driver_ndis: fixed static WEP configuration to avoid race condition
252 issues with some NDIS drivers between association and setting WEP
254 * driver_ndis: added validation for IELength value in scan results to
255 avoid crashes when using buggy NDIS drivers [Bug 165]
256 * fixed Release|Win32 target in the Visual Studio project files
257 (previously, only Debug|Win32 target was set properly)
258 * changed control interface API call wpa_ctrl_pending() to allow it to
259 return -1 on error (e.g., connection lost); control interface clients
260 will need to make sure that they verify that the value is indeed >0
261 when determining whether there are pending messages
262 * added an alternative control interface backend for Windows targets:
263 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
264 control interface mechanism for Windows builds (previously, UDP to
266 * changed ctrl_interface configuration for UNIX domain sockets:
267 - deprecated ctrl_interface_group variable (it may be removed in
269 - allow both directory and group be configured with ctrl_interface
270 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
271 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
272 case when group is not changed
273 * added support for controlling more than one interface per process in
275 * added a workaround for a case where the AP is using unknown address
276 (e.g., MAC address of the wired interface) as the source address for
277 EAPOL-Key frames; previously, that source address was used as the
278 destination for EAPOL-Key frames and in key derivation; now, BSSID is
279 used even if the source address does not match with it
280 (this resolves an interoperability issue with Thomson SpeedTouch 580)
281 * added a workaround for UDP-based control interface (which was used in
282 Windows builds before this release) to prevent packets with forged
283 addresses from being accepted as local control requests
284 * removed ndis_events.cpp and possibility of using external
285 ndis_events.exe; C version (ndis_events.c) is fully functional and
286 there is no desire to maintain two separate versions of this
288 * ndis_events: Changed NDIS event notification design to use WMI to
289 learn the adapter description through Win32_PnPEntity class; this
290 should fix some cases where the adapter name was not recognized
291 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
293 * fixed selection of the first network in ap_scan=2 mode; previously,
294 wpa_supplicant could get stuck in SCANNING state when only the first
295 network for enabled (e.g., after 'wpa_cli select_network 0')
296 * winsvc: added support for configuring ctrl_interface parameters in
297 registry (ctrl_interface string value in
298 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
299 required to enable control interface (previously, this was hardcoded
301 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
302 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
305 * fixed build with CONFIG_STAKEY=y [Bug 143]
306 * added support for doing MLME (IEEE 802.11 management frame
307 processing) in wpa_supplicant when using Devicescape IEEE 802.11
308 stack (wireless-dev.git tree)
309 * added a new network block configuration option, fragment_size, to
310 configure the maximum EAP fragment size
311 * driver_ndis: Disable WZC automatically for the selected interface to
312 avoid conflicts with two programs trying to control the radio; WZC
313 will be re-enabled (if it was enabled originally) when wpa_supplicant
315 * added an experimental TLSv1 client implementation
316 (CONFIG_TLS=internal) that can be used instead of an external TLS
317 library, e.g., to reduce total size requirement on systems that do
318 not include any TLS library by default (this is not yet complete;
319 basic functionality is there, but certificate validation is not yet
321 * added PeerKey handshake implementation for IEEE 802.11e
322 direct link setup (DLS) to replace STAKey handshake
323 * fixed WPA PSK update through ctrl_iface for the case where the old
324 PSK was derived from an ASCII passphrase and the new PSK is set as
325 a raw PSK (hex string)
326 * added new configuration option for identifying which network block
327 was used (id_str in wpa_supplicant.conf; included on
328 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
329 variable in wpa_cli action scripts; in addition WPA_ID variable is
330 set to the current unique identifier that wpa_supplicant assigned
331 automatically for the network and that can be used with
332 GET_NETWORK/SET_NETWORK ctrl_iface commands)
333 * wpa_cli action script is now called only when the connect/disconnect
334 status changes or when associating with a different network
335 * fixed configuration parser not to remove CCMP from group cipher list
336 if WPA-None (adhoc) is used (pairwise=NONE in that case)
337 * fixed integrated NDIS events processing not to hang the process due
338 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
339 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
340 draft-clancy-emu-eap-shared-secret-00.txt)
341 * added Microsoft Visual Studio 2005 solution and project files for
342 build wpa_supplicant for Windows (see vs2005 subdirectory)
343 * eloop_win: fixed unregistration of Windows events
344 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
345 at the end of RSN pre-authentication and added unregistration of
346 a Windows event to avoid getting eloop_win stuck with an invalid
348 * driver_ndis: added support for selecting AP based on BSSID
349 * added new environmental variable for wpa_cli action scripts:
350 WPA_CTRL_DIR is the current control interface directory
351 * driver_ndis: added support for using NDISUIO instead of WinPcap for
352 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
353 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
354 wpa_supplicant without requiring WinPcap; note that using NDISUIO
355 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
356 only one application to open the device
357 * changed NDIS driver naming to only include device GUID, e.g.,
358 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
359 specific \Device\NPF_ prefix before the GUID; the prefix is still
360 allowed for backwards compatibility, but it is not required anymore
361 when specifying the interface
362 * driver_ndis: re-initialize driver interface is the adapter is removed
363 and re-inserted [Bug 159]
364 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
365 big endian hosts [Bug 146]
368 * fixed EAP-GTC response to include correct user identity when run as
369 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
370 * driver_ndis: Fixed encryption mode configuration for unencrypted
371 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
372 refused to associate with open networks) [Bug 106]
373 * driver_ndis: use BSSID OID polling to detect when IBSS network is
374 formed even when ndis_events code is included since some NDIS drivers
375 do not generate media connect events in IBSS mode
376 * config_winreg: allow global ctrl_interface parameter to be configured
378 * config_winreg: added support for saving configuration data into
380 * added support for controlling network device operational state
381 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
382 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
383 that can use this information)
384 * driver_wext: added support for WE-21 change to SSID configuration
385 * driver_wext: fixed privacy configuration for static WEP keys mode
387 * added an optional driver_ops callback for MLME-SETPROTECTION.request
389 * added support for EAP-SAKE (no EAP method number allocated yet, so
390 this is using the same experimental type 255 as EAP-PSK)
391 * added support for dynamically loading EAP methods (.so files) instead
392 of requiring them to be statically linked in; this is disabled by
393 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
397 * do not try to use USIM APDUs when initializing PC/SC for SIM card
398 access for a network that has not enabled EAP-AKA
399 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
400 v0.5.1 due to the new support for expanded EAP types)
401 * added support for generating EAP Expanded Nak
402 * try to fetch scan results once before requesting new scan when
403 starting up in ap_scan=1 mode (this can speed up initial association
404 a lot with, e.g., madwifi-ng driver)
405 * added support for receiving EAPOL frames from a Linux bridge
406 interface (-bbr0 on command line)
407 * fixed EAPOL re-authentication for sessions that used PMKSA caching
408 * changed EAP method registration to use a dynamic list of methods
409 instead of a static list generated at build time
410 * fixed PMKSA cache deinitialization not to use freed memory when
411 removing PMKSA entries
412 * fixed a memory leak in EAP-TTLS re-authentication
413 * reject WPA/WPA2 message 3/4 if it does not include any valid
415 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
416 if the driver does not support SIOCSIWAUTH
419 * driver_test: added better support for multiple APs and STAs by using
420 a directory with sockets that include MAC address for each device in
421 the name (driver_param=test_dir=/tmp/test)
422 * added support for EAP expanded type (vendor specific EAP methods)
423 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
424 option can be changed if needed
425 * wpa_cli/wpa_gui: skip non-socket files in control directory when
426 using UNIX domain sockets; this avoids selecting an incorrect
427 interface (e.g., a PID file could be in this directory, even though
428 use of this directory for something else than socket files is not
430 * fixed TLS library deinitialization after RSN pre-authentication not
431 to disable TLS library for normal authentication
432 * driver_wext: Remove null-termination from SSID length if the driver
433 used it; some Linux drivers do this and they were causing problems in
434 wpa_supplicant not finding matching configuration block. This change
435 would break a case where the SSID actually ends in '\0', but that is
436 not likely to happen in real use.
437 * fixed PMKSA cache processing not to trigger deauthentication if the
438 current PMKSA cache entry is replaced with a valid new entry
439 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
440 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
443 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
444 * added experimental STAKey handshake implementation for IEEE 802.11e
445 direct link setup (DLS); note: this is disabled by default in both
446 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
448 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
449 decrypt AT_ENCR_DATA attributes correctly
450 * fixed EAP-AKA to allow resynchronization within the same session
451 * made code closer to ANSI C89 standard to make it easier to port to
452 other C libraries and compilers
453 * started moving operating system or C library specific functions into
454 wrapper functions defined in os.h and implemented in os_*.c to make
456 * wpa_supplicant can now be built with Microsoft Visual C++
457 (e.g., with the freely available Toolkit 2003 version or Visual
458 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
459 example makefile for nmake
460 * added support for using Windows registry for command line parameters
461 (CONFIG_MAIN=main_winsvc) and configuration data
462 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
463 contents; this version can be run both as a Windows service and as a
464 normal application; 'wpasvc.exe app' to start as applicant,
465 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
466 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
468 * made it possible to link ndis_events.exe functionality into
469 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
470 * added better support for multiple control interface backends
471 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
472 * fixed PC/SC code to use correct length for GSM AUTH command buffer
473 and to not use pioRecvPci with SCardTransmit() calls; these were not
474 causing visible problems with pcsc-lite, but Windows Winscard.dll
475 refused the previously used parameters; this fixes EAP-SIM and
476 EAP-AKA authentication using SIM/USIM card under Windows
477 * added new event loop implementation for Windows using
478 WaitForMultipleObject() instead of select() in order to allow waiting
479 for non-socket objects; this can be selected with
480 CONFIG_ELOOP=eloop_win in .config
481 * added support for selecting l2_packet implementation in .config
482 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
483 winpcap, freebsd, none)
484 * added new l2_packet implementation for WinPcap
485 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
486 reduce latency in EAPOL receive processing from about 100 ms to about
488 * added support for EAP-FAST key derivation using other ciphers than
489 RC4-128-SHA for authentication and AES128-SHA for provisioning
490 * added support for configuring CA certificate as DER file and as a
492 * fixed private key configuration as configuration blob and added
493 support for using PKCS#12 as a blob
494 * tls_gnutls: added support for using PKCS#12 files; added support for
496 * added support for loading trusted CA certificates from Windows
497 certificate store: ca_cert="cert_store://<name>", where <name> is
498 likely CA (Intermediate CA certificates) or ROOT (root certificates)
499 * added C version of ndis_events.cpp and made it possible to build this
500 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
501 easily on cross-compilation builds
502 * added wpasvc.exe into Windows binary release; this is an alternative
503 version of wpa_supplicant.exe with configuration backend using
504 Windows registry and with the entry point designed to run as a
506 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
507 wpasvc.exe and removed this additional tool from the Windows binary
508 release since it is not needed anymore
509 * load winscard.dll functions dynamically when building with MinGW
510 since MinGW does not yet include winscard library
512 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
513 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
514 and WinPcap to receive frames sent to PAE group address
515 * disable EAP state machine when IEEE 802.1X authentication is not used
516 in order to get rid of bogus "EAP failed" messages
517 * fixed OpenSSL error reporting to go through all pending errors to
518 avoid confusing reports of old errors being reported at later point
520 * fixed configuration file updating to not write empty variables
521 (e.g., proto or key_mgmt) that the file parser would not accept
522 * fixed ADD_NETWORK ctrl_iface command to use the same default values
523 for variables as empty network definitions read from config file
525 * fixed EAP state machine to not discard EAP-Failure messages in many
526 cases (e.g., during TLS handshake)
527 * fixed a infinite loop in private key reading if the configured file
528 cannot be parsed successfully
529 * driver_madwifi: added support for madwifi-ng
530 * wpa_gui: do not display password/PSK field contents
531 * wpa_gui: added CA certificate configuration
532 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
533 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
534 the new AP is using different WPA/RSN IE
535 * use longer timeout for IEEE 802.11 association to avoid problems with
536 drivers that may take more than five second to associate
539 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
540 RSN IE, but WPA IE would match with wpa_supplicant configuration
541 * added support for named configuration blobs in order to avoid having
542 to use file system for external files (e.g., certificates);
543 variables can be set to "blob://<blob name>" instead of file path to
544 use a named blob; supported fields: pac_file, client_cert,
546 * fixed RSN pre-authentication (it was broken in the clean up of WPA
547 state machine interface in v0.4.5)
548 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
549 sure the driver configures broadcast decryption correctly
550 * added ca_path (and ca_path2) configuration variables that can be used
551 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
552 system-wide trusted CA list
553 * added support for starting wpa_supplicant without a configuration
554 file (-C argument must be used to set ctrl_interface parameter for
555 this case; in addition, -p argument can be used to provide
556 driver_param; these new arguments can also be used with a
557 configuration to override the values from the configuration)
558 * added global control interface that can be optionally used for adding
559 and removing network interfaces dynamically (-g command line argument
560 for both wpa_supplicant and wpa_cli) without having to restart
561 wpa_supplicant process
563 - try to save configuration whenever something is modified
564 - added WEP key configuration
565 - added possibility to edit the current network configuration
566 * driver_ndis: fixed driver polling not to increase frequency on each
567 received EAPOL frame due to incorrectly cancelled timeout
568 * added simple configuration file examples (in examples subdirectory)
569 * fixed driver_wext.c to filter wireless events based on ifindex to
570 avoid interfaces receiving events from other interfaces
571 * delay sending initial EAPOL-Start couple of seconds to speed up
572 authentication for the most common case of Authenticator starting
573 EAP authentication immediately after association
576 * added a workaround for clearing keys with ndiswrapper to allow
577 roaming from WPA enabled AP to plaintext one
578 * added docbook documentation (doc/docbook) that can be used to
579 generate, e.g., man pages
580 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
581 PF_PACKET in order to prepare for network devices that do not use
582 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
583 * use receipt of EAPOL-Key frame as a lower layer success indication
584 for EAP state machine to allow recovery from dropped EAP-Success
586 * cleaned up internal EAPOL frame processing by not including link
587 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
588 header is added only when transmitted the frame; this makes it easier
589 to use wpa_supplicant on link layers that use different header than
591 * updated EAP-PSK to use draft 9 by default since this can now be
592 tested with hostapd; removed support for draft 3, including
593 server_nai configuration option from network blocks
594 * driver_wired: add PAE address to the multicast address list in order
595 to be able to receive EAPOL frames with drivers that do not include
596 these multicast addresses by default
597 * driver_wext: add support for WE-19
598 * added support for multiple configuration backends (CONFIG_BACKEND
599 option); currently, only 'file' is supported (i.e., the format used
600 in wpa_supplicant.conf)
601 * added support for updating configuration ('wpa_cli save_config');
602 this is disabled by default and can be enabled with global
603 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
604 and wpa_gui to store the configuration changes in a permanent store
605 * added GET_NETWORK ctrl_iface command
606 (e.g., 'wpa_cli get_network 0 ssid')
609 * replaced OpenSSL patch for EAP-FAST support
610 (openssl-tls-extensions.patch) with a more generic and correct
611 patch (the new patch is not compatible with the previous one, so the
612 OpenSSL library will need to be patched with the new patch in order
613 to be able to build wpa_supplicant with EAP-FAST support)
614 * added support for using Windows certificate store (through CryptoAPI)
615 for client certificate and private key operations (EAP-TLS)
616 (see wpa_supplicant.conf for more information on how to configure
617 this with private_key)
618 * ported wpa_gui to Windows
619 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
620 built with the open source version of the Qt4 for Windows
621 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
622 with drivers that do not support WPA
623 * ndis_events: fixed Windows 2000 support
624 * added support for enabling/disabling networks from the list of all
625 configured networks ('wpa_cli enable_network <network id>' and
626 'wpa_cli disable_network <network id>')
627 * added support for adding and removing network from the current
628 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
629 <network id>'); added networks are disabled by default and they can
630 be enabled with enable_network command once the configuration is done
631 for the new network; note: configuration file is not yet updated, so
632 these new networks are lost when wpa_supplicant is restarted
633 * added support for setting network configuration parameters through
634 the control interface, for example:
635 wpa_cli set_network 0 ssid "\"my network\""
636 * fixed parsing of strings that include both " and # within double
637 quoted area (e.g., "start"#end")
638 * added EAP workaround for PEAP session resumption: allow outer,
639 i.e., not tunneled, EAP-Success to terminate session since; this can
640 be disabled with eap_workaround=0
641 (this was allowed for PEAPv1 before, but now it is also allowed for
642 PEAPv0 since at least one RADIUS authentication server seems to be
643 doing this for PEAPv0, too)
644 * wpa_gui: added preliminary support for adding new networks to the
645 wpa_supplicant configuration (double click on the scan results to
646 open network configuration)
649 * removed interface for external EAPOL/EAP supplicant (e.g.,
650 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
651 anymore and is unlikely to be used by anyone
652 * driver_ndis: fixed WinPcap 3.0 support
653 * fixed build with CONFIG_DNET_PCAP=y on Linux
654 * l2_packet: moved different implementations into separate files
658 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
659 (note: ipw2100-1.1.0 is likely to require an update to work with
661 * added support for using ap_scan=2 mode with multiple network blocks;
662 wpa_supplicant will go through the networks one by one until the
663 driver reports a successful association; this uses the same order for
664 networks as scan_ssid=1 scans, i.e., the priority field is ignored
665 and the network block order in the file is used instead
666 * fixed a potential issue in RSN pre-authentication ending up using
667 freed memory if pre-authentication times out
668 * added support for matching alternative subject name extensions of the
669 authentication server certificate; new configuration variables
670 altsubject_match and altsubject_match2
671 * driver_ndis: added support for IEEE 802.1X authentication with wired
673 * added support for querying private key password (EAP-TLS) through the
674 control interface (wpa_cli/wpa_gui) if one is not included in the
676 * driver_broadcom: fixed couple of memory leaks in scan result
678 * EAP-PAX is now registered as EAP type 46
679 * fixed EAP-PAX MAC calculation
680 * fixed EAP-PAX CK and ICK key derivation
681 * added support for using password with EAP-PAX (as an alternative to
682 entering key with eappsk); SHA-1 hash of the password will be used as
684 * added support for arbitrary driver interface parameters through the
685 configuration file with a new driver_param field; this adds a new
686 driver_ops function set_param()
687 * added possibility to override l2_packet module with driver interface
688 API (new send_eapol handler); this can be used to implement driver
689 specific TX/RX functions for EAPOL frames
690 * fixed ctrl_interface_group processing for the case where gid is
691 entered as a number, not group name
692 * driver_test: added support for testing hostapd with wpa_supplicant
693 by using test driver interface without any kernel drivers or network
697 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
698 packets to be encrypted; this was apparently broken by the changed
699 ioctl order in v0.4.0
700 * driver_madwifi: added preliminary support for compiling against 'BSD'
701 branch of madwifi CVS tree
702 * added support for EAP-MSCHAPv2 password retries within the same EAP
703 authentication session
704 * added support for password changes with EAP-MSCHAPv2 (used when the
705 password has expired)
706 * added support for reading additional certificates from PKCS#12 files
707 and adding them to the certificate chain
708 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
710 * fixed a possible double free in EAP-TTLS fast-reauthentication when
711 identity or password is entered through control interface
712 * display EAP Notification messages to user through control interface
713 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
714 * added GUI version of wpa_cli, wpa_gui; this is not build
715 automatically with 'make'; use 'make wpa_gui' to build (this requires
716 Qt development tools)
717 * added 'disconnect' command to control interface for setting
718 wpa_supplicant in state where it will not associate before
719 'reassociate' command has been used
720 * added support for selecting a network from the list of all configured
721 networks ('wpa_cli select_network <network id>'; this disabled all
722 other networks; to re-enable, 'wpa_cli select_network any')
723 * added support for getting scan results through control interface
724 * added EAP workaround for PEAPv1 session resumption: allow outer,
725 i.e., not tunneled, EAP-Success to terminate session since; this can
726 be disabled with eap_workaround=0
728 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
729 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
730 used to reduce the size of the wpa_supplicant considerably if
731 debugging code is not needed
732 * fixed EAPOL-Key validation to drop packets with invalid Key Data
733 Length; such frames could have crashed wpa_supplicant due to buffer
735 * added support for wired authentication (IEEE 802.1X on wired
736 Ethernet); driver interface 'wired'
737 * obsoleted set_wpa() handler in the driver interface API (it can be
738 replaced by moving enable/disable functionality into init()/deinit())
739 (calls to set_wpa() are still present for backwards compatibility,
740 but they may be removed in the future)
741 * driver_madwifi: fixed association in plaintext mode
742 * modified the EAP workaround that accepts EAP-Success with incorrect
743 Identifier to be even less strict about verification in order to
744 interoperate with some authentication servers
745 * added support for sending TLS alerts
746 * added support for 'any' SSID wildcard; if ssid is not configured or
747 is set to an empty string, any SSID will be accepted for non-WPA AP
748 * added support for asking PIN (for SIM) from frontends (e.g.,
749 wpa_cli); if a PIN is needed, but not included in the configuration
750 file, a control interface request is sent and EAP processing is
751 delayed until the PIN is available
752 * added support for using external devices (e.g., a smartcard) for
753 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
754 new wpa_supplicant.conf variables:
755 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
756 - network: engine, engine_id, key_id
757 * added experimental support for EAP-PAX
758 * added monitor mode for wpa_cli (-a<path to a program to run>) that
759 allows external commands (e.g., shell scripts) to be run based on
760 wpa_supplicant events, e.g., when authentication has been completed
761 and data connection is ready; other related wpa_cli arguments:
762 -B (run in background), -P (write PID file); wpa_supplicant has a new
763 command line argument (-W) that can be used to make it wait until a
764 control interface command is received in order to avoid missing
766 * added support for opportunistic WPA2 PMKSA key caching (disabled by
767 default, can be enabled with proactive_key_caching=1)
768 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
769 Authenticator rejects PMKSA caching attempt and the driver is not
770 using assoc_info events
771 * added -P<pid file> argument for wpa_supplicant to write the current
772 process id into a file
774 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
775 * added new phase1 option parameter, include_tls_length=1, to force
776 wpa_supplicant to add TLS Message Length field to all TLS messages
777 even if the packet is not fragmented; this may be needed with some
778 authentication servers
779 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
780 using drivers that take care of AP selection (e.g., when using
782 * fixed reprocessing of pending request after ctrl_iface requests for
783 identity/password/otp
784 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
785 EAP-PEAP and EAP-TTLS
786 * all drivers using driver_wext: set interface up and select Managed
787 mode when starting wpa_supplicant; set interface down when exiting
788 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
789 ipw2100 and ipw2200; please note that this also changed the
790 configuration variable in .config to CONFIG_DRIVER_IPW
793 * fixed a busy loop introduced in v0.3.5 for scan result processing
794 when no matching AP is found
797 * added a workaround for an interoperability issue with a Cisco AP
799 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
800 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
801 retransmission of dropped frames)
802 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
803 (e.g., segfault when processing EAPOL-Key frames)
804 * fixed EAP workaround and fast reauthentication configuration for
805 RSN pre-authentication; previously these were disabled and
806 pre-authentication would fail if the used authentication server
807 requires EAP workarounds
808 * added support for blacklisting APs that fail or timeout
809 authentication in ap_scan=1 mode so that all APs are tried in cases
810 where the ones with strongest signal level are failing authentication
811 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
812 authentication attempt
813 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
814 in the previous authentication (previously, only Phase 1 success was
818 * added preliminary support for IBSS (ad-hoc) mode configuration
819 (mode=1 in network block); this included a new key_mgmt mode
820 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
821 key management; see wpa_supplicant.conf for more details and an
822 example on how to configure this (note: this is currently implemented
823 only for driver_hostapd.c, but the changes should be trivial to add
824 in associate() handler for other drivers, too (assuming the driver
826 * added preliminary port for native Windows (i.e., no cygwin) using
830 * added optional support for GNU Readline and History Libraries for
831 wpa_cli (CONFIG_READLINE)
832 * cleaned up EAP state machine <-> method interface and number of
833 small problems with error case processing not terminating on
834 EAP-Failure but waiting for timeout
835 * added couple of workarounds for interoperability issues with a
836 Cisco AP when using WPA2
837 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
838 Note: This requires a patch for openssl to add support for TLS
839 extensions and number of workarounds for operations without
840 certificates. Proof of concept type of experimental patch is
841 included in openssl-tls-extensions.patch.
844 * fixed private key loading for cases where passphrase is not set
845 * fixed Windows/cygwin L2 packet handler freeing; previous version
846 could cause a segfault when RSN pre-authentication was completed
847 * added support for PMKSA caching with drivers that generate RSN IEs
848 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
849 but similar code can be easily added to driver_ndiswrapper.c once
850 ndiswrapper gets full support for RSN PMKSA caching
851 * improved recovery from PMKID mismatches by requesting full EAP
852 authentication in case of failed PMKSA caching attempt
853 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
854 (this requires that ndis_events is ran while wpa_supplicant is
856 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
857 * added support for driver interfaces to replace the interface name
858 based on driver/OS specific mapping, e.g., in case of driver_ndis,
859 this allows the beginning of the adapter description to be used as
861 * added support for CR+LF (Windows-style) line ends in configuration
863 * driver_ndis: enable radio before starting scanning, disable radio
865 * modified association event handler to set portEnabled = FALSE before
866 clearing port Valid in order to reset EAP state machine and avoid
867 problems with new authentication getting ignored because of state
868 machines ending up in AUTHENTICATED/SUCCESS state based on old
870 * added support for driver events to add PMKID candidates in order to
871 allow drivers to give priority to most likely roaming candidates
872 * driver_hostap: moved PrivacyInvoked configuration to associate()
873 function so that this will not be set for plaintext connections
874 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
875 interface can distinguish plaintext and IEEE 802.1X (no WPA)
877 * fixed static WEP key configuration to use broadcast/default type for
878 all keys (previously, the default TX key was configured as pairwise/
880 * driver_ndis: added legacy WPA capability detection for non-WPA2
882 * added support for setting static WEP keys for IEEE 802.1X without
883 dynamic WEP keying (eapol_flags=0)
886 * added support for reading PKCS#12 (PFX) files (as a replacement for
887 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
888 * fixed compilation with CONFIG_PCSC=y
889 * added new ap_scan mode, ap_scan=2, for drivers that take care of
890 association, but need to be configured with security policy and SSID,
891 e.g., ndiswrapper and NDIS driver; this mode should allow such
892 drivers to work with hidden SSIDs and optimized roaming; when
893 ap_scan=2 is used, only the first network block in the configuration
894 file is used and this configuration should have explicit security
895 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
896 group, proto variables
897 * added experimental port of wpa_supplicant for Windows
898 - driver_ndis.c driver interface (NDIS OIDs)
899 - currently, this requires cygwin and WinPcap
900 - small utility, win_if_list, can be used to get interface name
901 * control interface can now be removed at build time; add
902 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
903 * optional Xsupplicant interface can now be removed at build time;
904 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
905 * added auth_alg to driver interface associate() parameters to make it
906 easier for drivers to configure authentication algorithm as part of
909 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
910 * driver_broadcom: added new driver interface for Broadcom wl.o driver
911 (a generic driver for Broadcom IEEE 802.11a/g cards)
912 * wpa_cli: fixed parsing of -p <path> command line argument
913 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
914 ACK, not tunneled EAP-Success (of which only the first byte was
915 actually send due to a bug in previous code); this seems to
916 interoperate with most RADIUS servers that implements PEAPv1
917 * PEAPv1: added support for terminating PEAP authentication on tunneled
918 EAP-Success message; this can be configured by adding
919 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
920 (some RADIUS servers require this whereas others require a tunneled
922 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
923 the old label for key derivation; previously, the default was 1,
924 but it looks like most existing PEAPv1 implementations use the old
925 label which is thus more suitable default option
926 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
927 * fixed parsing of wep_tx_keyidx
928 * added support for configuring list of allowed Phase 2 EAP types
929 (for both EAP-PEAP and EAP-TTLS) instead of only one type
930 * added support for configuring IEEE 802.11 authentication algorithm
931 (auth_alg; mainly for using Shared Key authentication with static
933 * added support for EAP-AKA (with UMTS SIM)
934 * fixed couple of errors in PCSC handling that could have caused
935 random-looking errors for EAP-SIM
936 * added support for EAP-SIM pseudonyms and fast re-authentication
937 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
939 * added support for EAP-SIM with two challanges
940 (phase1="sim_min_num_chal=3" can be used to require three challenges)
941 * added support for configuring DH/DSA parameters for an ephemeral DH
942 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
943 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
944 and optional DH key exchange to achieve forward secracy with RSA keys
945 * added support for matching subject of the authentication server
946 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
947 configuration variables subject_match and subject_match2
948 * changed SSID configuration in driver_wext.c (used by many driver
949 interfaces) to use ssid_len+1 as the length for SSID since some Linux
951 * fixed couple of unaligned reads in scan result parsing to fix WPA
952 connection on some platforms (e.g., ARM)
953 * added driver interface for Intel ipw2100 driver
954 * added support for LEAP with WPA
955 * added support for larger scan results report (old limit was 4 kB of
956 data, i.e., about 35 or so APs) when using Linux wireless extensions
958 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
959 only if there is a PMKSA cache entry for the current AP
960 * fixed error handling for case where reading of scan results fails:
961 must schedule a new scan or wpa_supplicant will remain waiting
963 * changed debug output to remove shared password/key material by
964 default; all key information can be included with -K command line
965 argument to match the previous behavior
966 * added support for timestamping debug log messages (disabled by
967 default, can be enabled with -t command line argument)
968 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
969 if keys are not configured to be used; this fixes IEEE 802.1X mode
970 with drivers that use this information to configure whether Privacy
971 bit can be in Beacon frames (e.g., ndiswrapper)
972 * avoid clearing driver keys if no keys have been configured since last
973 key clear request; this seems to improve reliability of group key
974 handshake for ndiswrapper & NDIS driver which seems to be suffering
975 of some kind of timing issue when the keys are cleared again after
977 * changed driver interface API:
978 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
979 version is being used (now, this is set to 2; previously, it was
981 - pass pointer to private data structure to all calls
982 - the new API is not backwards compatible; all in-tree driver
983 interfaces has been converted to the new API
984 * added support for controlling multiple interfaces (radios) per
985 wpa_supplicant process; each interface needs to be listed on the
986 command line (-c, -i, -D arguments) with -N as a separator
987 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
988 * added a workaround for EAP servers that incorrectly use same Id for
989 sequential EAP packets
990 * changed libpcap/libdnet configuration to use .config variable,
991 CONFIG_DNET_PCAP, instead of requiring Makefile modification
992 * improved downgrade attack detection in IE verification of msg 3/4:
993 verify both WPA and RSN IEs, if present, not only the selected one;
994 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
995 Probe Response frame, and RSN is enabled in wpa_supplicant
997 * fixed WPA msg 3/4 processing to allow Key Data field contain other
998 IEs than just one WPA IE
999 * added support for FreeBSD and driver interface for the BSD net80211
1000 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
1001 required kernel mods have not yet been committed
1002 * made EAP workarounds configurable; enabled by default, can be
1003 disabled with network block option eap_workaround=0
1005 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
1006 * resolved couple of interoperability issues with EAP-PEAPv1 and
1007 Phase 2 (inner EAP) fragment reassembly
1008 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
1009 AP is using non-zero key index for the unicast key and key index zero
1010 for the broadcast key
1011 * driver_hostap: fixed IEEE 802.1X WEP key updates and
1012 re-authentication by allowing unencrypted EAPOL frames when not using
1014 * added a new driver interface, 'wext', which uses only standard,
1015 driver independent functionality in Linux wireless extensions;
1016 currently, this can be used only for non-WPA IEEE 802.1X mode, but
1017 eventually, this is to be extended to support full WPA/WPA2 once
1018 Linux wireless extensions get support for this
1019 * added support for mode in which the driver is responsible for AP
1020 scanning and selection; this is disabled by default and can be
1021 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
1022 this mode can be used, e.g., with generic 'wext' driver interface to
1023 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
1024 supporting wireless extensions.
1025 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
1026 operation with an AP that does not include SSID in the Beacon frames)
1027 * added support for new EAP authentication methods:
1028 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
1029 * added support for asking one-time-passwords from frontends (e.g.,
1030 wpa_cli); this 'otp' command works otherwise like 'password' command,
1031 but the password is used only once and the frontend will be asked for
1032 a new password whenever a request from authenticator requires a
1033 password; this can be used with both EAP-OTP and EAP-GTC
1034 * changed wpa_cli to automatically re-establish connection so that it
1035 does not need to be re-started when wpa_supplicant is terminated and
1037 * improved user data (identity/password/otp) requests through
1038 frontends: process pending EAPOL packets after getting new
1039 information so that full authentication does not need to be
1040 restarted; in addition, send pending requests again whenever a new
1041 frontend is attached
1042 * changed control frontends to use a new directory for socket files to
1043 make it easier for wpa_cli to automatically select between interfaces
1044 and to provide access control for the control interface;
1045 wpa_supplicant.conf: ctrl_interface is now a path
1046 (/var/run/wpa_supplicant is the recommended path) and
1047 ctrl_interface_group can be used to select which group gets access to
1048 the control interface;
1049 wpa_cli: by default, try to connect to the first interface available
1050 in /var/run/wpa_supplicant; this path can be overriden with -p option
1051 and an interface can be selected with -i option (i.e., in most common
1052 cases, wpa_cli does not need to get any arguments)
1053 * added support for LEAP
1054 * added driver interface for Linux ndiswrapper
1055 * added priority option for network blocks in the configuration file;
1056 this allows networks to be grouped based on priority (the scan
1057 results are searched for matches with network blocks in this order)
1060 * sort scan results to improve AP selection
1061 * fixed control interface socket removal for some error cases
1062 * improved scan requesting and authentication timeout
1063 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1065 * PEAP version can now be forced with phase1="peapver=<ver>"
1066 (mostly for testing; by default, the highest version supported by
1067 both the Supplicant and Authentication Server is selected
1069 * added support for madwifi driver (Atheros ar521x)
1070 * added a workaround for cases where AP sets Install Tx/Rx bit for
1071 WPA Group Key messages when pairwise keys are used (without this,
1072 the Group Key would be used for Tx and the AP would drop frames
1074 * added GSM SIM/USIM interface for GSM authentication algorithm for
1075 EAP-SIM; this requires pcsc-lite
1076 * added support for ATMEL AT76C5XXx driver
1077 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1078 does not include key data in the EAPOL-Key frame (i.e., part of
1079 EAP keying material is used as data encryption key)
1080 * added support for using plaintext and static WEP networks
1084 * added support for new EAP authentication methods:
1085 EAP-TTLS/EAP-MD5-Challenge
1087 EAP-TTLS/EAP-MSCHAPv2
1095 EAP-PEAP/MD5-Challenge
1097 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1098 * added support for anonymous identity (to be used when identity is
1099 sent in plaintext; real identity will be used within TLS protected
1100 tunnel (e.g., with EAP-TTLS)
1101 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1102 * added support for requesting identity and password information using
1103 control interface; in other words, the password for EAP-PEAP or
1104 EAP-TTLS does not need to be included in the configuration file since
1105 a frontand (e.g., wpa_cli) can ask it from the user
1106 * improved RSN pre-authentication to use a candidate list and process
1107 all candidates from each scan; not only one per scan
1108 * fixed RSN IE and WPA IE capabilities field parsing
1109 * ignore Tx bit in GTK IE when Pairwise keys are used
1110 * avoid making new scan requests during IEEE 802.1X negotiation
1111 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1112 with TLS support (this replaces the included implementation with
1113 library code to save about 8 kB since the library code is needed
1115 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1116 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1119 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1121 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1122 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1123 - EAP-MD5 (cannot be used with WPA-RADIUS)
1124 [draft-ietf-eap-rfc2284bis-09.txt]
1125 - EAP-TLS [RFC 2716]
1126 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1127 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1128 [draft-kamath-pppext-eap-mschapv2-00.txt]
1129 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1130 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1131 - new configuration file options: eap, identity, password, ca_cert,
1132 client_cert, privatekey, private_key_passwd
1133 - Xsupplicant is not required anymore, but it can be used by
1134 disabling the internal IEEE 802.1X Supplicant with -e command line
1136 - this code is not included in the default build; Makefile need to
1137 be edited for this (uncomment lines for selected functionality)
1138 - EAP-TLS and EAP-PEAP require openssl libraries
1139 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1140 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1141 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1142 EAPOL-Key frames instead of WPA key handshakes)
1143 * added support for IEEE 802.11i/RSN (WPA2)
1144 - improved PTK Key Handshake
1145 - PMKSA caching, pre-authentication
1146 * fixed wpa_supplicant to ignore possible extra data after WPA
1147 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1148 TPTK' error from message 3 of 4-Way Handshake in case the AP
1149 includes extra data after the EAPOL-Key)
1150 * added interface for external programs (frontends) to control
1152 - CLI example (wpa_cli) with interactive mode and command line
1154 - replaced SIGUSR1 status/statistics with the new control interface
1155 * made some feature compile time configurable
1156 - .config file for make
1157 - driver interfaces (hostap, hermes, ..)
1158 - EAPOL/EAP functions
1161 * Initial version of wpa_supplicant
