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
19 * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
20 (can be used to simulate test SIM/USIM card with a known private key;
21 enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
22 and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
23 * added a new network configuration option, wpa_ptk_rekey, that can be
24 used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
25 against TKIP deficiencies
26 * added an optional mitigation mechanism for certain attacks against
27 TKIP by delaying Michael MIC error reports by a random amount of time
28 between 0 and 60 seconds; this can be enabled with a build option
29 CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
30 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
32 * updated OpenSSL code for EAP-FAST to use an updated version of the
33 session ticket overriding API that was included into the upstream
34 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
35 needed with that version anymore)
36 * updated userspace MLME instructions to match with the current Linux
37 mac80211 implementation; please also note that this can only be used
38 with driver_nl80211.c (the old code from driver_wext.c was removed)
39 * added support (Linux only) for RoboSwitch chipsets (often found in
40 consumer grade routers); driver interface 'roboswitch'
41 * fixed canceling of PMKSA caching when using drivers that generate
42 RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
46 * added support for SHA-256 as X.509 certificate digest when using the
47 internal X.509/TLSv1 implementation
48 * updated management frame protection to use IEEE 802.11w/D6.0
49 * added support for using SHA256-based stronger key derivation for WPA2
51 * fixed FT (IEEE 802.11r) authentication after a failed association to
53 * added support for configuring Phase 2 (inner/tunneled) authentication
54 method with wpa_gui-qt4
57 * added support for EAP Sequences in EAP-FAST Phase 2
58 * added support for using TNC with EAP-FAST
59 * added driver_ps3 for the PS3 Linux wireless driver
60 * added support for optional cryptobinding with PEAPv0
61 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
62 allow fallback to full handshake if server rejects PAC-Opaque
63 * added fragmentation support for EAP-TNC
64 * added support for parsing PKCS #8 formatted private keys into the
65 internal TLS implementation (both PKCS #1 RSA key and PKCS #8
66 encapsulated RSA key can now be used)
67 * added option of using faster, but larger, routines in the internal
68 LibTomMath (for internal TLS implementation) to speed up DH and RSA
69 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
70 * fixed race condition between disassociation event and group key
71 handshake to avoid getting stuck in incorrect state [Bug 261]
72 * fixed opportunistic key caching (proactive_key_caching)
75 * removed 'nai' and 'eappsk' network configuration variables that were
76 previously used for configuring user identity and key for EAP-PSK,
77 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
78 replacement for 'nai' (if old configuration used a separate
79 'identity' value, that would now be configured as
80 'anonymous_identity'). 'password' field is now used as the
81 replacement for 'eappsk' (it can also be set using hexstring to
82 present random binary data)
83 * removed '-w' command line parameter (wait for interface to be added,
84 if needed); cleaner way of handling this functionality is to use an
85 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
86 when an interface is added
87 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
88 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
89 indicating when new scan results become available
90 * added new ctrl_iface command, BSS, to allow scan results to be
91 fetched without hitting the message size limits (this command
92 can be used to iterate through the scan results one BSS at the time)
93 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
94 attributes in EAP-SIM Start/Response when using fast reauthentication
95 * fixed EAPOL not to end up in infinite loop when processing dynamic
96 WEP keys with IEEE 802.1X
97 * fixed problems in getting NDIS events from WMI on Windows 2000
100 * added support for Makefile builds to include debug-log-to-a-file
101 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
102 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
103 lengths properly to avoid potential crash caused by invalid messages
104 * added data structure for storing allocated buffers (struct wpabuf);
105 this does not affect wpa_supplicant usage, but many of the APIs
106 changed and various interfaces (e.g., EAP) is not compatible with old
108 * added support for protecting EAP-AKA/Identity messages with
109 AT_CHECKCODE (optional feature in RFC 4187)
110 * added support for protected result indication with AT_RESULT_IND for
111 EAP-SIM and EAP-AKA (phase1="result_ind=1")
112 * added driver_wext workaround for race condition between scanning and
113 association with drivers that take very long time to scan all
114 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
115 using a longer hardcoded timeout for the scan if the driver supports
116 notifications for scan completion (SIOCGIWSCAN event); this helps,
117 e.g., in cases where wpa_supplicant and madwifi driver ended up in
118 loop where the driver did not even try to associate
119 * stop EAPOL timer tick when no timers are in use in order to reduce
120 power consumption (no need to wake up the process once per second)
122 * added support for privilege separation (run only minimal part of
123 wpa_supplicant functionality as root and rest as unprivileged,
124 non-root process); see 'Privilege separation' in README for details;
125 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
127 * changed scan results data structure to include all information
128 elements to make it easier to support new IEs; old get_scan_result()
129 driver_ops is still supported for backwards compatibility (results
130 are converted internally to the new format), but all drivers should
131 start using the new get_scan_results2() to make them more likely to
132 work with new features
133 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
134 application, i.e., it does not require Qt3Support anymore; Windows
135 binary of wpa_gui.exe is now from this directory and only requires
136 QtCore4.dll and QtGui4.dll libraries
137 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
138 available as a separate package to make wpa_gui installation easier:
139 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
140 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
141 only shared key/password authentication is supported in this version
144 * added support for configuring password as NtPasswordHash
145 (16-byte MD4 hash of password) in hash:<32 hex digits> format
146 * added support for fallback from abbreviated TLS handshake to
147 full handshake when using EAP-FAST (e.g., due to an expired
149 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
150 draft (draft-ietf-emu-eap-gpsk-07.txt)
151 * added support for drivers that take care of RSN 4-way handshake
152 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
153 WPA_ALG_PMK in set_key)
154 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
155 .config); this version supports only ap_scan=2 mode and allow the
156 driver to take care of the 4-way handshake
157 * fixed a buffer overflow in parsing TSF from scan results when using
158 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
160 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
161 * fixed an integer overflow issue in the ASN.1 parser used by the
162 (experimental) internal TLS implementation to avoid a potential
164 * fixed a race condition with -W option (wait for a control interface
165 monitor before starting) that could have caused the first messages to
167 * added support for processing TNCC-TNCS-Messages to report
168 recommendation (allow/none/isolate) when using TNC [Bug 243]
171 * added network configuration parameter 'frequency' for setting
172 initial channel for IBSS (adhoc) networks
173 * added experimental IEEE 802.11r/D6.0 support
174 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
175 * updated EAP-PSK to use the IANA-allocated EAP type 47
176 * fixed EAP-PAX key derivation
177 * fixed EAP-PSK bit ordering of the Flags field
178 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
179 tunnelled identity request (previously, the identifier from the outer
180 method was used, not the tunnelled identifier which could be
182 * added support for fragmentation of outer TLS packets during Phase 2
183 of EAP-PEAP/TTLS/FAST
184 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
185 * added support for EAP-FAST authentication with inner methods that
186 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
187 for PAC provisioning)
188 * added support for authenticated EAP-FAST provisioning
189 * added support for configuring maximum number of EAP-FAST PACs to
190 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
191 * added support for storing EAP-FAST PACs in binary format
192 (fast_pac_format=binary in phase1 string)
193 * fixed dbus ctrl_iface to validate message interface before
194 dispatching to avoid a possible segfault [Bug 190]
195 * fixed PeerKey key derivation to use the correct PRF label
196 * updated Windows binary build to link against OpenSSL 0.9.8d and
197 added support for EAP-FAST
198 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
199 draft (draft-ietf-emu-eap-gpsk-04.txt)
200 * fixed EAP-AKA Notification processing to allow Notification to be
201 processed after AKA Challenge response has been sent
202 * updated to use IEEE 802.11w/D2.0 for management frame protection
204 * fixed EAP-TTLS implementation not to crash on use of freed memory
205 if TLS library initialization fails
206 * added support for EAP-TNC (Trusted Network Connect)
207 (this version implements the EAP-TNC method and EAP-TTLS changes
208 needed to run two methods in sequence (IF-T) and the IF-IMC and
209 IF-TNCCS interfaces from TNCC)
212 * added experimental, integrated TLSv1 client implementation with the
213 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
214 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
215 .config); this can be useful, e.g., if the target system does not
216 have a suitable TLS library and a minimal code size is required
217 (total size of this internal TLS/crypto code is bit under 50 kB on
218 x86 and the crypto code is shared by rest of the supplicant so some
219 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
220 * removed STAKey handshake since PeerKey handshake has replaced it in
221 IEEE 802.11ma and there are no known deployments of STAKey
222 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
223 draft (draft-ietf-emu-eap-gpsk-01.txt)
224 * added preliminary implementation of IEEE 802.11w/D1.0 (management
226 (Note: this requires driver support to work properly.)
227 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
228 * fixed Windows named pipes ctrl_iface to not stop listening for
229 commands if client program opens a named pipe and closes it
230 immediately without sending a command
231 * fixed USIM PIN status determination for the case that PIN is not
232 needed (this allows EAP-AKA to be used with USIM cards that do not
234 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
235 be used with cards that do not support file selection based on
237 * added support for matching the subjectAltName of the authentication
238 server certificate against multiple name components (e.g.,
239 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
240 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
241 affects IEEE 802.1X with dynamic WEP keys)
242 * changed ctrl_iface network configuration 'get' operations to not
243 return password/key material; if these fields are requested, "*"
244 will be returned if the password/key is set, but the value of the
245 parameter is not exposed
248 * added support for building Windows version with UNICODE defined
249 (wide-char functions)
250 * driver_ndis: fixed static WEP configuration to avoid race condition
251 issues with some NDIS drivers between association and setting WEP
253 * driver_ndis: added validation for IELength value in scan results to
254 avoid crashes when using buggy NDIS drivers [Bug 165]
255 * fixed Release|Win32 target in the Visual Studio project files
256 (previously, only Debug|Win32 target was set properly)
257 * changed control interface API call wpa_ctrl_pending() to allow it to
258 return -1 on error (e.g., connection lost); control interface clients
259 will need to make sure that they verify that the value is indeed >0
260 when determining whether there are pending messages
261 * added an alternative control interface backend for Windows targets:
262 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
263 control interface mechanism for Windows builds (previously, UDP to
265 * changed ctrl_interface configuration for UNIX domain sockets:
266 - deprecated ctrl_interface_group variable (it may be removed in
268 - allow both directory and group be configured with ctrl_interface
269 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
270 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
271 case when group is not changed
272 * added support for controlling more than one interface per process in
274 * added a workaround for a case where the AP is using unknown address
275 (e.g., MAC address of the wired interface) as the source address for
276 EAPOL-Key frames; previously, that source address was used as the
277 destination for EAPOL-Key frames and in key derivation; now, BSSID is
278 used even if the source address does not match with it
279 (this resolves an interoperability issue with Thomson SpeedTouch 580)
280 * added a workaround for UDP-based control interface (which was used in
281 Windows builds before this release) to prevent packets with forged
282 addresses from being accepted as local control requests
283 * removed ndis_events.cpp and possibility of using external
284 ndis_events.exe; C version (ndis_events.c) is fully functional and
285 there is no desire to maintain two separate versions of this
287 * ndis_events: Changed NDIS event notification design to use WMI to
288 learn the adapter description through Win32_PnPEntity class; this
289 should fix some cases where the adapter name was not recognized
290 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
292 * fixed selection of the first network in ap_scan=2 mode; previously,
293 wpa_supplicant could get stuck in SCANNING state when only the first
294 network for enabled (e.g., after 'wpa_cli select_network 0')
295 * winsvc: added support for configuring ctrl_interface parameters in
296 registry (ctrl_interface string value in
297 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
298 required to enable control interface (previously, this was hardcoded
300 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
301 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
304 * fixed build with CONFIG_STAKEY=y [Bug 143]
305 * added support for doing MLME (IEEE 802.11 management frame
306 processing) in wpa_supplicant when using Devicescape IEEE 802.11
307 stack (wireless-dev.git tree)
308 * added a new network block configuration option, fragment_size, to
309 configure the maximum EAP fragment size
310 * driver_ndis: Disable WZC automatically for the selected interface to
311 avoid conflicts with two programs trying to control the radio; WZC
312 will be re-enabled (if it was enabled originally) when wpa_supplicant
314 * added an experimental TLSv1 client implementation
315 (CONFIG_TLS=internal) that can be used instead of an external TLS
316 library, e.g., to reduce total size requirement on systems that do
317 not include any TLS library by default (this is not yet complete;
318 basic functionality is there, but certificate validation is not yet
320 * added PeerKey handshake implementation for IEEE 802.11e
321 direct link setup (DLS) to replace STAKey handshake
322 * fixed WPA PSK update through ctrl_iface for the case where the old
323 PSK was derived from an ASCII passphrase and the new PSK is set as
324 a raw PSK (hex string)
325 * added new configuration option for identifying which network block
326 was used (id_str in wpa_supplicant.conf; included on
327 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
328 variable in wpa_cli action scripts; in addition WPA_ID variable is
329 set to the current unique identifier that wpa_supplicant assigned
330 automatically for the network and that can be used with
331 GET_NETWORK/SET_NETWORK ctrl_iface commands)
332 * wpa_cli action script is now called only when the connect/disconnect
333 status changes or when associating with a different network
334 * fixed configuration parser not to remove CCMP from group cipher list
335 if WPA-None (adhoc) is used (pairwise=NONE in that case)
336 * fixed integrated NDIS events processing not to hang the process due
337 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
338 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
339 draft-clancy-emu-eap-shared-secret-00.txt)
340 * added Microsoft Visual Studio 2005 solution and project files for
341 build wpa_supplicant for Windows (see vs2005 subdirectory)
342 * eloop_win: fixed unregistration of Windows events
343 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
344 at the end of RSN pre-authentication and added unregistration of
345 a Windows event to avoid getting eloop_win stuck with an invalid
347 * driver_ndis: added support for selecting AP based on BSSID
348 * added new environmental variable for wpa_cli action scripts:
349 WPA_CTRL_DIR is the current control interface directory
350 * driver_ndis: added support for using NDISUIO instead of WinPcap for
351 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
352 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
353 wpa_supplicant without requiring WinPcap; note that using NDISUIO
354 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
355 only one application to open the device
356 * changed NDIS driver naming to only include device GUID, e.g.,
357 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
358 specific \Device\NPF_ prefix before the GUID; the prefix is still
359 allowed for backwards compatibility, but it is not required anymore
360 when specifying the interface
361 * driver_ndis: re-initialize driver interface is the adapter is removed
362 and re-inserted [Bug 159]
363 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
364 big endian hosts [Bug 146]
367 * fixed EAP-GTC response to include correct user identity when run as
368 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
369 * driver_ndis: Fixed encryption mode configuration for unencrypted
370 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
371 refused to associate with open networks) [Bug 106]
372 * driver_ndis: use BSSID OID polling to detect when IBSS network is
373 formed even when ndis_events code is included since some NDIS drivers
374 do not generate media connect events in IBSS mode
375 * config_winreg: allow global ctrl_interface parameter to be configured
377 * config_winreg: added support for saving configuration data into
379 * added support for controlling network device operational state
380 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
381 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
382 that can use this information)
383 * driver_wext: added support for WE-21 change to SSID configuration
384 * driver_wext: fixed privacy configuration for static WEP keys mode
386 * added an optional driver_ops callback for MLME-SETPROTECTION.request
388 * added support for EAP-SAKE (no EAP method number allocated yet, so
389 this is using the same experimental type 255 as EAP-PSK)
390 * added support for dynamically loading EAP methods (.so files) instead
391 of requiring them to be statically linked in; this is disabled by
392 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
396 * do not try to use USIM APDUs when initializing PC/SC for SIM card
397 access for a network that has not enabled EAP-AKA
398 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
399 v0.5.1 due to the new support for expanded EAP types)
400 * added support for generating EAP Expanded Nak
401 * try to fetch scan results once before requesting new scan when
402 starting up in ap_scan=1 mode (this can speed up initial association
403 a lot with, e.g., madwifi-ng driver)
404 * added support for receiving EAPOL frames from a Linux bridge
405 interface (-bbr0 on command line)
406 * fixed EAPOL re-authentication for sessions that used PMKSA caching
407 * changed EAP method registration to use a dynamic list of methods
408 instead of a static list generated at build time
409 * fixed PMKSA cache deinitialization not to use freed memory when
410 removing PMKSA entries
411 * fixed a memory leak in EAP-TTLS re-authentication
412 * reject WPA/WPA2 message 3/4 if it does not include any valid
414 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
415 if the driver does not support SIOCSIWAUTH
418 * driver_test: added better support for multiple APs and STAs by using
419 a directory with sockets that include MAC address for each device in
420 the name (driver_param=test_dir=/tmp/test)
421 * added support for EAP expanded type (vendor specific EAP methods)
422 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
423 option can be changed if needed
424 * wpa_cli/wpa_gui: skip non-socket files in control directory when
425 using UNIX domain sockets; this avoids selecting an incorrect
426 interface (e.g., a PID file could be in this directory, even though
427 use of this directory for something else than socket files is not
429 * fixed TLS library deinitialization after RSN pre-authentication not
430 to disable TLS library for normal authentication
431 * driver_wext: Remove null-termination from SSID length if the driver
432 used it; some Linux drivers do this and they were causing problems in
433 wpa_supplicant not finding matching configuration block. This change
434 would break a case where the SSID actually ends in '\0', but that is
435 not likely to happen in real use.
436 * fixed PMKSA cache processing not to trigger deauthentication if the
437 current PMKSA cache entry is replaced with a valid new entry
438 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
439 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
442 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
443 * added experimental STAKey handshake implementation for IEEE 802.11e
444 direct link setup (DLS); note: this is disabled by default in both
445 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
447 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
448 decrypt AT_ENCR_DATA attributes correctly
449 * fixed EAP-AKA to allow resynchronization within the same session
450 * made code closer to ANSI C89 standard to make it easier to port to
451 other C libraries and compilers
452 * started moving operating system or C library specific functions into
453 wrapper functions defined in os.h and implemented in os_*.c to make
455 * wpa_supplicant can now be built with Microsoft Visual C++
456 (e.g., with the freely available Toolkit 2003 version or Visual
457 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
458 example makefile for nmake
459 * added support for using Windows registry for command line parameters
460 (CONFIG_MAIN=main_winsvc) and configuration data
461 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
462 contents; this version can be run both as a Windows service and as a
463 normal application; 'wpasvc.exe app' to start as applicant,
464 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
465 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
467 * made it possible to link ndis_events.exe functionality into
468 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
469 * added better support for multiple control interface backends
470 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
471 * fixed PC/SC code to use correct length for GSM AUTH command buffer
472 and to not use pioRecvPci with SCardTransmit() calls; these were not
473 causing visible problems with pcsc-lite, but Windows Winscard.dll
474 refused the previously used parameters; this fixes EAP-SIM and
475 EAP-AKA authentication using SIM/USIM card under Windows
476 * added new event loop implementation for Windows using
477 WaitForMultipleObject() instead of select() in order to allow waiting
478 for non-socket objects; this can be selected with
479 CONFIG_ELOOP=eloop_win in .config
480 * added support for selecting l2_packet implementation in .config
481 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
482 winpcap, freebsd, none)
483 * added new l2_packet implementation for WinPcap
484 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
485 reduce latency in EAPOL receive processing from about 100 ms to about
487 * added support for EAP-FAST key derivation using other ciphers than
488 RC4-128-SHA for authentication and AES128-SHA for provisioning
489 * added support for configuring CA certificate as DER file and as a
491 * fixed private key configuration as configuration blob and added
492 support for using PKCS#12 as a blob
493 * tls_gnutls: added support for using PKCS#12 files; added support for
495 * added support for loading trusted CA certificates from Windows
496 certificate store: ca_cert="cert_store://<name>", where <name> is
497 likely CA (Intermediate CA certificates) or ROOT (root certificates)
498 * added C version of ndis_events.cpp and made it possible to build this
499 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
500 easily on cross-compilation builds
501 * added wpasvc.exe into Windows binary release; this is an alternative
502 version of wpa_supplicant.exe with configuration backend using
503 Windows registry and with the entry point designed to run as a
505 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
506 wpasvc.exe and removed this additional tool from the Windows binary
507 release since it is not needed anymore
508 * load winscard.dll functions dynamically when building with MinGW
509 since MinGW does not yet include winscard library
511 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
512 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
513 and WinPcap to receive frames sent to PAE group address
514 * disable EAP state machine when IEEE 802.1X authentication is not used
515 in order to get rid of bogus "EAP failed" messages
516 * fixed OpenSSL error reporting to go through all pending errors to
517 avoid confusing reports of old errors being reported at later point
519 * fixed configuration file updating to not write empty variables
520 (e.g., proto or key_mgmt) that the file parser would not accept
521 * fixed ADD_NETWORK ctrl_iface command to use the same default values
522 for variables as empty network definitions read from config file
524 * fixed EAP state machine to not discard EAP-Failure messages in many
525 cases (e.g., during TLS handshake)
526 * fixed a infinite loop in private key reading if the configured file
527 cannot be parsed successfully
528 * driver_madwifi: added support for madwifi-ng
529 * wpa_gui: do not display password/PSK field contents
530 * wpa_gui: added CA certificate configuration
531 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
532 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
533 the new AP is using different WPA/RSN IE
534 * use longer timeout for IEEE 802.11 association to avoid problems with
535 drivers that may take more than five second to associate
538 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
539 RSN IE, but WPA IE would match with wpa_supplicant configuration
540 * added support for named configuration blobs in order to avoid having
541 to use file system for external files (e.g., certificates);
542 variables can be set to "blob://<blob name>" instead of file path to
543 use a named blob; supported fields: pac_file, client_cert,
545 * fixed RSN pre-authentication (it was broken in the clean up of WPA
546 state machine interface in v0.4.5)
547 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
548 sure the driver configures broadcast decryption correctly
549 * added ca_path (and ca_path2) configuration variables that can be used
550 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
551 system-wide trusted CA list
552 * added support for starting wpa_supplicant without a configuration
553 file (-C argument must be used to set ctrl_interface parameter for
554 this case; in addition, -p argument can be used to provide
555 driver_param; these new arguments can also be used with a
556 configuration to override the values from the configuration)
557 * added global control interface that can be optionally used for adding
558 and removing network interfaces dynamically (-g command line argument
559 for both wpa_supplicant and wpa_cli) without having to restart
560 wpa_supplicant process
562 - try to save configuration whenever something is modified
563 - added WEP key configuration
564 - added possibility to edit the current network configuration
565 * driver_ndis: fixed driver polling not to increase frequency on each
566 received EAPOL frame due to incorrectly cancelled timeout
567 * added simple configuration file examples (in examples subdirectory)
568 * fixed driver_wext.c to filter wireless events based on ifindex to
569 avoid interfaces receiving events from other interfaces
570 * delay sending initial EAPOL-Start couple of seconds to speed up
571 authentication for the most common case of Authenticator starting
572 EAP authentication immediately after association
575 * added a workaround for clearing keys with ndiswrapper to allow
576 roaming from WPA enabled AP to plaintext one
577 * added docbook documentation (doc/docbook) that can be used to
578 generate, e.g., man pages
579 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
580 PF_PACKET in order to prepare for network devices that do not use
581 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
582 * use receipt of EAPOL-Key frame as a lower layer success indication
583 for EAP state machine to allow recovery from dropped EAP-Success
585 * cleaned up internal EAPOL frame processing by not including link
586 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
587 header is added only when transmitted the frame; this makes it easier
588 to use wpa_supplicant on link layers that use different header than
590 * updated EAP-PSK to use draft 9 by default since this can now be
591 tested with hostapd; removed support for draft 3, including
592 server_nai configuration option from network blocks
593 * driver_wired: add PAE address to the multicast address list in order
594 to be able to receive EAPOL frames with drivers that do not include
595 these multicast addresses by default
596 * driver_wext: add support for WE-19
597 * added support for multiple configuration backends (CONFIG_BACKEND
598 option); currently, only 'file' is supported (i.e., the format used
599 in wpa_supplicant.conf)
600 * added support for updating configuration ('wpa_cli save_config');
601 this is disabled by default and can be enabled with global
602 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
603 and wpa_gui to store the configuration changes in a permanent store
604 * added GET_NETWORK ctrl_iface command
605 (e.g., 'wpa_cli get_network 0 ssid')
608 * replaced OpenSSL patch for EAP-FAST support
609 (openssl-tls-extensions.patch) with a more generic and correct
610 patch (the new patch is not compatible with the previous one, so the
611 OpenSSL library will need to be patched with the new patch in order
612 to be able to build wpa_supplicant with EAP-FAST support)
613 * added support for using Windows certificate store (through CryptoAPI)
614 for client certificate and private key operations (EAP-TLS)
615 (see wpa_supplicant.conf for more information on how to configure
616 this with private_key)
617 * ported wpa_gui to Windows
618 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
619 built with the open source version of the Qt4 for Windows
620 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
621 with drivers that do not support WPA
622 * ndis_events: fixed Windows 2000 support
623 * added support for enabling/disabling networks from the list of all
624 configured networks ('wpa_cli enable_network <network id>' and
625 'wpa_cli disable_network <network id>')
626 * added support for adding and removing network from the current
627 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
628 <network id>'); added networks are disabled by default and they can
629 be enabled with enable_network command once the configuration is done
630 for the new network; note: configuration file is not yet updated, so
631 these new networks are lost when wpa_supplicant is restarted
632 * added support for setting network configuration parameters through
633 the control interface, for example:
634 wpa_cli set_network 0 ssid "\"my network\""
635 * fixed parsing of strings that include both " and # within double
636 quoted area (e.g., "start"#end")
637 * added EAP workaround for PEAP session resumption: allow outer,
638 i.e., not tunneled, EAP-Success to terminate session since; this can
639 be disabled with eap_workaround=0
640 (this was allowed for PEAPv1 before, but now it is also allowed for
641 PEAPv0 since at least one RADIUS authentication server seems to be
642 doing this for PEAPv0, too)
643 * wpa_gui: added preliminary support for adding new networks to the
644 wpa_supplicant configuration (double click on the scan results to
645 open network configuration)
648 * removed interface for external EAPOL/EAP supplicant (e.g.,
649 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
650 anymore and is unlikely to be used by anyone
651 * driver_ndis: fixed WinPcap 3.0 support
652 * fixed build with CONFIG_DNET_PCAP=y on Linux
653 * l2_packet: moved different implementations into separate files
657 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
658 (note: ipw2100-1.1.0 is likely to require an update to work with
660 * added support for using ap_scan=2 mode with multiple network blocks;
661 wpa_supplicant will go through the networks one by one until the
662 driver reports a successful association; this uses the same order for
663 networks as scan_ssid=1 scans, i.e., the priority field is ignored
664 and the network block order in the file is used instead
665 * fixed a potential issue in RSN pre-authentication ending up using
666 freed memory if pre-authentication times out
667 * added support for matching alternative subject name extensions of the
668 authentication server certificate; new configuration variables
669 altsubject_match and altsubject_match2
670 * driver_ndis: added support for IEEE 802.1X authentication with wired
672 * added support for querying private key password (EAP-TLS) through the
673 control interface (wpa_cli/wpa_gui) if one is not included in the
675 * driver_broadcom: fixed couple of memory leaks in scan result
677 * EAP-PAX is now registered as EAP type 46
678 * fixed EAP-PAX MAC calculation
679 * fixed EAP-PAX CK and ICK key derivation
680 * added support for using password with EAP-PAX (as an alternative to
681 entering key with eappsk); SHA-1 hash of the password will be used as
683 * added support for arbitrary driver interface parameters through the
684 configuration file with a new driver_param field; this adds a new
685 driver_ops function set_param()
686 * added possibility to override l2_packet module with driver interface
687 API (new send_eapol handler); this can be used to implement driver
688 specific TX/RX functions for EAPOL frames
689 * fixed ctrl_interface_group processing for the case where gid is
690 entered as a number, not group name
691 * driver_test: added support for testing hostapd with wpa_supplicant
692 by using test driver interface without any kernel drivers or network
696 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
697 packets to be encrypted; this was apparently broken by the changed
698 ioctl order in v0.4.0
699 * driver_madwifi: added preliminary support for compiling against 'BSD'
700 branch of madwifi CVS tree
701 * added support for EAP-MSCHAPv2 password retries within the same EAP
702 authentication session
703 * added support for password changes with EAP-MSCHAPv2 (used when the
704 password has expired)
705 * added support for reading additional certificates from PKCS#12 files
706 and adding them to the certificate chain
707 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
709 * fixed a possible double free in EAP-TTLS fast-reauthentication when
710 identity or password is entered through control interface
711 * display EAP Notification messages to user through control interface
712 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
713 * added GUI version of wpa_cli, wpa_gui; this is not build
714 automatically with 'make'; use 'make wpa_gui' to build (this requires
715 Qt development tools)
716 * added 'disconnect' command to control interface for setting
717 wpa_supplicant in state where it will not associate before
718 'reassociate' command has been used
719 * added support for selecting a network from the list of all configured
720 networks ('wpa_cli select_network <network id>'; this disabled all
721 other networks; to re-enable, 'wpa_cli select_network any')
722 * added support for getting scan results through control interface
723 * added EAP workaround for PEAPv1 session resumption: allow outer,
724 i.e., not tunneled, EAP-Success to terminate session since; this can
725 be disabled with eap_workaround=0
727 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
728 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
729 used to reduce the size of the wpa_supplicant considerably if
730 debugging code is not needed
731 * fixed EAPOL-Key validation to drop packets with invalid Key Data
732 Length; such frames could have crashed wpa_supplicant due to buffer
734 * added support for wired authentication (IEEE 802.1X on wired
735 Ethernet); driver interface 'wired'
736 * obsoleted set_wpa() handler in the driver interface API (it can be
737 replaced by moving enable/disable functionality into init()/deinit())
738 (calls to set_wpa() are still present for backwards compatibility,
739 but they may be removed in the future)
740 * driver_madwifi: fixed association in plaintext mode
741 * modified the EAP workaround that accepts EAP-Success with incorrect
742 Identifier to be even less strict about verification in order to
743 interoperate with some authentication servers
744 * added support for sending TLS alerts
745 * added support for 'any' SSID wildcard; if ssid is not configured or
746 is set to an empty string, any SSID will be accepted for non-WPA AP
747 * added support for asking PIN (for SIM) from frontends (e.g.,
748 wpa_cli); if a PIN is needed, but not included in the configuration
749 file, a control interface request is sent and EAP processing is
750 delayed until the PIN is available
751 * added support for using external devices (e.g., a smartcard) for
752 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
753 new wpa_supplicant.conf variables:
754 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
755 - network: engine, engine_id, key_id
756 * added experimental support for EAP-PAX
757 * added monitor mode for wpa_cli (-a<path to a program to run>) that
758 allows external commands (e.g., shell scripts) to be run based on
759 wpa_supplicant events, e.g., when authentication has been completed
760 and data connection is ready; other related wpa_cli arguments:
761 -B (run in background), -P (write PID file); wpa_supplicant has a new
762 command line argument (-W) that can be used to make it wait until a
763 control interface command is received in order to avoid missing
765 * added support for opportunistic WPA2 PMKSA key caching (disabled by
766 default, can be enabled with proactive_key_caching=1)
767 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
768 Authenticator rejects PMKSA caching attempt and the driver is not
769 using assoc_info events
770 * added -P<pid file> argument for wpa_supplicant to write the current
771 process id into a file
773 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
774 * added new phase1 option parameter, include_tls_length=1, to force
775 wpa_supplicant to add TLS Message Length field to all TLS messages
776 even if the packet is not fragmented; this may be needed with some
777 authentication servers
778 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
779 using drivers that take care of AP selection (e.g., when using
781 * fixed reprocessing of pending request after ctrl_iface requests for
782 identity/password/otp
783 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
784 EAP-PEAP and EAP-TTLS
785 * all drivers using driver_wext: set interface up and select Managed
786 mode when starting wpa_supplicant; set interface down when exiting
787 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
788 ipw2100 and ipw2200; please note that this also changed the
789 configuration variable in .config to CONFIG_DRIVER_IPW
792 * fixed a busy loop introduced in v0.3.5 for scan result processing
793 when no matching AP is found
796 * added a workaround for an interoperability issue with a Cisco AP
798 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
799 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
800 retransmission of dropped frames)
801 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
802 (e.g., segfault when processing EAPOL-Key frames)
803 * fixed EAP workaround and fast reauthentication configuration for
804 RSN pre-authentication; previously these were disabled and
805 pre-authentication would fail if the used authentication server
806 requires EAP workarounds
807 * added support for blacklisting APs that fail or timeout
808 authentication in ap_scan=1 mode so that all APs are tried in cases
809 where the ones with strongest signal level are failing authentication
810 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
811 authentication attempt
812 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
813 in the previous authentication (previously, only Phase 1 success was
817 * added preliminary support for IBSS (ad-hoc) mode configuration
818 (mode=1 in network block); this included a new key_mgmt mode
819 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
820 key management; see wpa_supplicant.conf for more details and an
821 example on how to configure this (note: this is currently implemented
822 only for driver_hostapd.c, but the changes should be trivial to add
823 in associate() handler for other drivers, too (assuming the driver
825 * added preliminary port for native Windows (i.e., no cygwin) using
829 * added optional support for GNU Readline and History Libraries for
830 wpa_cli (CONFIG_READLINE)
831 * cleaned up EAP state machine <-> method interface and number of
832 small problems with error case processing not terminating on
833 EAP-Failure but waiting for timeout
834 * added couple of workarounds for interoperability issues with a
835 Cisco AP when using WPA2
836 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
837 Note: This requires a patch for openssl to add support for TLS
838 extensions and number of workarounds for operations without
839 certificates. Proof of concept type of experimental patch is
840 included in openssl-tls-extensions.patch.
843 * fixed private key loading for cases where passphrase is not set
844 * fixed Windows/cygwin L2 packet handler freeing; previous version
845 could cause a segfault when RSN pre-authentication was completed
846 * added support for PMKSA caching with drivers that generate RSN IEs
847 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
848 but similar code can be easily added to driver_ndiswrapper.c once
849 ndiswrapper gets full support for RSN PMKSA caching
850 * improved recovery from PMKID mismatches by requesting full EAP
851 authentication in case of failed PMKSA caching attempt
852 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
853 (this requires that ndis_events is ran while wpa_supplicant is
855 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
856 * added support for driver interfaces to replace the interface name
857 based on driver/OS specific mapping, e.g., in case of driver_ndis,
858 this allows the beginning of the adapter description to be used as
860 * added support for CR+LF (Windows-style) line ends in configuration
862 * driver_ndis: enable radio before starting scanning, disable radio
864 * modified association event handler to set portEnabled = FALSE before
865 clearing port Valid in order to reset EAP state machine and avoid
866 problems with new authentication getting ignored because of state
867 machines ending up in AUTHENTICATED/SUCCESS state based on old
869 * added support for driver events to add PMKID candidates in order to
870 allow drivers to give priority to most likely roaming candidates
871 * driver_hostap: moved PrivacyInvoked configuration to associate()
872 function so that this will not be set for plaintext connections
873 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
874 interface can distinguish plaintext and IEEE 802.1X (no WPA)
876 * fixed static WEP key configuration to use broadcast/default type for
877 all keys (previously, the default TX key was configured as pairwise/
879 * driver_ndis: added legacy WPA capability detection for non-WPA2
881 * added support for setting static WEP keys for IEEE 802.1X without
882 dynamic WEP keying (eapol_flags=0)
885 * added support for reading PKCS#12 (PFX) files (as a replacement for
886 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
887 * fixed compilation with CONFIG_PCSC=y
888 * added new ap_scan mode, ap_scan=2, for drivers that take care of
889 association, but need to be configured with security policy and SSID,
890 e.g., ndiswrapper and NDIS driver; this mode should allow such
891 drivers to work with hidden SSIDs and optimized roaming; when
892 ap_scan=2 is used, only the first network block in the configuration
893 file is used and this configuration should have explicit security
894 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
895 group, proto variables
896 * added experimental port of wpa_supplicant for Windows
897 - driver_ndis.c driver interface (NDIS OIDs)
898 - currently, this requires cygwin and WinPcap
899 - small utility, win_if_list, can be used to get interface name
900 * control interface can now be removed at build time; add
901 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
902 * optional Xsupplicant interface can now be removed at build time;
903 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
904 * added auth_alg to driver interface associate() parameters to make it
905 easier for drivers to configure authentication algorithm as part of
908 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
909 * driver_broadcom: added new driver interface for Broadcom wl.o driver
910 (a generic driver for Broadcom IEEE 802.11a/g cards)
911 * wpa_cli: fixed parsing of -p <path> command line argument
912 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
913 ACK, not tunneled EAP-Success (of which only the first byte was
914 actually send due to a bug in previous code); this seems to
915 interoperate with most RADIUS servers that implements PEAPv1
916 * PEAPv1: added support for terminating PEAP authentication on tunneled
917 EAP-Success message; this can be configured by adding
918 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
919 (some RADIUS servers require this whereas others require a tunneled
921 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
922 the old label for key derivation; previously, the default was 1,
923 but it looks like most existing PEAPv1 implementations use the old
924 label which is thus more suitable default option
925 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
926 * fixed parsing of wep_tx_keyidx
927 * added support for configuring list of allowed Phase 2 EAP types
928 (for both EAP-PEAP and EAP-TTLS) instead of only one type
929 * added support for configuring IEEE 802.11 authentication algorithm
930 (auth_alg; mainly for using Shared Key authentication with static
932 * added support for EAP-AKA (with UMTS SIM)
933 * fixed couple of errors in PCSC handling that could have caused
934 random-looking errors for EAP-SIM
935 * added support for EAP-SIM pseudonyms and fast re-authentication
936 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
938 * added support for EAP-SIM with two challanges
939 (phase1="sim_min_num_chal=3" can be used to require three challenges)
940 * added support for configuring DH/DSA parameters for an ephemeral DH
941 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
942 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
943 and optional DH key exchange to achieve forward secracy with RSA keys
944 * added support for matching subject of the authentication server
945 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
946 configuration variables subject_match and subject_match2
947 * changed SSID configuration in driver_wext.c (used by many driver
948 interfaces) to use ssid_len+1 as the length for SSID since some Linux
950 * fixed couple of unaligned reads in scan result parsing to fix WPA
951 connection on some platforms (e.g., ARM)
952 * added driver interface for Intel ipw2100 driver
953 * added support for LEAP with WPA
954 * added support for larger scan results report (old limit was 4 kB of
955 data, i.e., about 35 or so APs) when using Linux wireless extensions
957 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
958 only if there is a PMKSA cache entry for the current AP
959 * fixed error handling for case where reading of scan results fails:
960 must schedule a new scan or wpa_supplicant will remain waiting
962 * changed debug output to remove shared password/key material by
963 default; all key information can be included with -K command line
964 argument to match the previous behavior
965 * added support for timestamping debug log messages (disabled by
966 default, can be enabled with -t command line argument)
967 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
968 if keys are not configured to be used; this fixes IEEE 802.1X mode
969 with drivers that use this information to configure whether Privacy
970 bit can be in Beacon frames (e.g., ndiswrapper)
971 * avoid clearing driver keys if no keys have been configured since last
972 key clear request; this seems to improve reliability of group key
973 handshake for ndiswrapper & NDIS driver which seems to be suffering
974 of some kind of timing issue when the keys are cleared again after
976 * changed driver interface API:
977 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
978 version is being used (now, this is set to 2; previously, it was
980 - pass pointer to private data structure to all calls
981 - the new API is not backwards compatible; all in-tree driver
982 interfaces has been converted to the new API
983 * added support for controlling multiple interfaces (radios) per
984 wpa_supplicant process; each interface needs to be listed on the
985 command line (-c, -i, -D arguments) with -N as a separator
986 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
987 * added a workaround for EAP servers that incorrectly use same Id for
988 sequential EAP packets
989 * changed libpcap/libdnet configuration to use .config variable,
990 CONFIG_DNET_PCAP, instead of requiring Makefile modification
991 * improved downgrade attack detection in IE verification of msg 3/4:
992 verify both WPA and RSN IEs, if present, not only the selected one;
993 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
994 Probe Response frame, and RSN is enabled in wpa_supplicant
996 * fixed WPA msg 3/4 processing to allow Key Data field contain other
997 IEs than just one WPA IE
998 * added support for FreeBSD and driver interface for the BSD net80211
999 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
1000 required kernel mods have not yet been committed
1001 * made EAP workarounds configurable; enabled by default, can be
1002 disabled with network block option eap_workaround=0
1004 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
1005 * resolved couple of interoperability issues with EAP-PEAPv1 and
1006 Phase 2 (inner EAP) fragment reassembly
1007 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
1008 AP is using non-zero key index for the unicast key and key index zero
1009 for the broadcast key
1010 * driver_hostap: fixed IEEE 802.1X WEP key updates and
1011 re-authentication by allowing unencrypted EAPOL frames when not using
1013 * added a new driver interface, 'wext', which uses only standard,
1014 driver independent functionality in Linux wireless extensions;
1015 currently, this can be used only for non-WPA IEEE 802.1X mode, but
1016 eventually, this is to be extended to support full WPA/WPA2 once
1017 Linux wireless extensions get support for this
1018 * added support for mode in which the driver is responsible for AP
1019 scanning and selection; this is disabled by default and can be
1020 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
1021 this mode can be used, e.g., with generic 'wext' driver interface to
1022 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
1023 supporting wireless extensions.
1024 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
1025 operation with an AP that does not include SSID in the Beacon frames)
1026 * added support for new EAP authentication methods:
1027 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
1028 * added support for asking one-time-passwords from frontends (e.g.,
1029 wpa_cli); this 'otp' command works otherwise like 'password' command,
1030 but the password is used only once and the frontend will be asked for
1031 a new password whenever a request from authenticator requires a
1032 password; this can be used with both EAP-OTP and EAP-GTC
1033 * changed wpa_cli to automatically re-establish connection so that it
1034 does not need to be re-started when wpa_supplicant is terminated and
1036 * improved user data (identity/password/otp) requests through
1037 frontends: process pending EAPOL packets after getting new
1038 information so that full authentication does not need to be
1039 restarted; in addition, send pending requests again whenever a new
1040 frontend is attached
1041 * changed control frontends to use a new directory for socket files to
1042 make it easier for wpa_cli to automatically select between interfaces
1043 and to provide access control for the control interface;
1044 wpa_supplicant.conf: ctrl_interface is now a path
1045 (/var/run/wpa_supplicant is the recommended path) and
1046 ctrl_interface_group can be used to select which group gets access to
1047 the control interface;
1048 wpa_cli: by default, try to connect to the first interface available
1049 in /var/run/wpa_supplicant; this path can be overriden with -p option
1050 and an interface can be selected with -i option (i.e., in most common
1051 cases, wpa_cli does not need to get any arguments)
1052 * added support for LEAP
1053 * added driver interface for Linux ndiswrapper
1054 * added priority option for network blocks in the configuration file;
1055 this allows networks to be grouped based on priority (the scan
1056 results are searched for matches with network blocks in this order)
1059 * sort scan results to improve AP selection
1060 * fixed control interface socket removal for some error cases
1061 * improved scan requesting and authentication timeout
1062 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1064 * PEAP version can now be forced with phase1="peapver=<ver>"
1065 (mostly for testing; by default, the highest version supported by
1066 both the Supplicant and Authentication Server is selected
1068 * added support for madwifi driver (Atheros ar521x)
1069 * added a workaround for cases where AP sets Install Tx/Rx bit for
1070 WPA Group Key messages when pairwise keys are used (without this,
1071 the Group Key would be used for Tx and the AP would drop frames
1073 * added GSM SIM/USIM interface for GSM authentication algorithm for
1074 EAP-SIM; this requires pcsc-lite
1075 * added support for ATMEL AT76C5XXx driver
1076 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1077 does not include key data in the EAPOL-Key frame (i.e., part of
1078 EAP keying material is used as data encryption key)
1079 * added support for using plaintext and static WEP networks
1083 * added support for new EAP authentication methods:
1084 EAP-TTLS/EAP-MD5-Challenge
1086 EAP-TTLS/EAP-MSCHAPv2
1094 EAP-PEAP/MD5-Challenge
1096 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1097 * added support for anonymous identity (to be used when identity is
1098 sent in plaintext; real identity will be used within TLS protected
1099 tunnel (e.g., with EAP-TTLS)
1100 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1101 * added support for requesting identity and password information using
1102 control interface; in other words, the password for EAP-PEAP or
1103 EAP-TTLS does not need to be included in the configuration file since
1104 a frontand (e.g., wpa_cli) can ask it from the user
1105 * improved RSN pre-authentication to use a candidate list and process
1106 all candidates from each scan; not only one per scan
1107 * fixed RSN IE and WPA IE capabilities field parsing
1108 * ignore Tx bit in GTK IE when Pairwise keys are used
1109 * avoid making new scan requests during IEEE 802.1X negotiation
1110 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1111 with TLS support (this replaces the included implementation with
1112 library code to save about 8 kB since the library code is needed
1114 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1115 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1118 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1120 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1121 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1122 - EAP-MD5 (cannot be used with WPA-RADIUS)
1123 [draft-ietf-eap-rfc2284bis-09.txt]
1124 - EAP-TLS [RFC 2716]
1125 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1126 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1127 [draft-kamath-pppext-eap-mschapv2-00.txt]
1128 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1129 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1130 - new configuration file options: eap, identity, password, ca_cert,
1131 client_cert, privatekey, private_key_passwd
1132 - Xsupplicant is not required anymore, but it can be used by
1133 disabling the internal IEEE 802.1X Supplicant with -e command line
1135 - this code is not included in the default build; Makefile need to
1136 be edited for this (uncomment lines for selected functionality)
1137 - EAP-TLS and EAP-PEAP require openssl libraries
1138 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1139 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1140 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1141 EAPOL-Key frames instead of WPA key handshakes)
1142 * added support for IEEE 802.11i/RSN (WPA2)
1143 - improved PTK Key Handshake
1144 - PMKSA caching, pre-authentication
1145 * fixed wpa_supplicant to ignore possible extra data after WPA
1146 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1147 TPTK' error from message 3 of 4-Way Handshake in case the AP
1148 includes extra data after the EAPOL-Key)
1149 * added interface for external programs (frontends) to control
1151 - CLI example (wpa_cli) with interactive mode and command line
1153 - replaced SIGUSR1 status/statistics with the new control interface
1154 * made some feature compile time configurable
1155 - .config file for make
1156 - driver interfaces (hostap, hermes, ..)
1157 - EAPOL/EAP functions
1160 * Initial version of wpa_supplicant
