1 ChangeLog for wpa_supplicant
4 * added support for Wi-Fi Protected Setup (WPS)
5 (wpa_supplicant can now be configured to act as a WPS Enrollee to
6 enroll credentials for a network using PIN and PBC methods; in
7 addition, wpa_supplicant can act as a wireless WPS Registrar to
8 configure an AP); WPS support can be enabled by adding CONFIG_WPS=y
9 into .config and setting the runtime configuration variables in
10 wpa_supplicant.conf (see WPS section in the example configuration
11 file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to
12 manage WPS negotiation; see README-WPS for more details
13 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
14 * added support for using driver_test over UDP socket
15 * fixed PEAPv0 Cryptobinding interoperability issue with Windows Server
16 2008 NPS; optional cryptobinding is now enabled (again) by default
17 * fixed PSK editing in wpa_gui
18 * changed EAP-GPSK to use the IANA assigned EAP method type 51
21 * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
22 (can be used to simulate test SIM/USIM card with a known private key;
23 enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
24 and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
25 * added a new network configuration option, wpa_ptk_rekey, that can be
26 used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
27 against TKIP deficiencies
28 * added an optional mitigation mechanism for certain attacks against
29 TKIP by delaying Michael MIC error reports by a random amount of time
30 between 0 and 60 seconds; this can be enabled with a build option
31 CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
32 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
34 * updated OpenSSL code for EAP-FAST to use an updated version of the
35 session ticket overriding API that was included into the upstream
36 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
37 needed with that version anymore)
38 * updated userspace MLME instructions to match with the current Linux
39 mac80211 implementation; please also note that this can only be used
40 with driver_nl80211.c (the old code from driver_wext.c was removed)
41 * added support (Linux only) for RoboSwitch chipsets (often found in
42 consumer grade routers); driver interface 'roboswitch'
43 * fixed canceling of PMKSA caching when using drivers that generate
44 RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
48 * added support for SHA-256 as X.509 certificate digest when using the
49 internal X.509/TLSv1 implementation
50 * updated management frame protection to use IEEE 802.11w/D6.0
51 * added support for using SHA256-based stronger key derivation for WPA2
53 * fixed FT (IEEE 802.11r) authentication after a failed association to
55 * added support for configuring Phase 2 (inner/tunneled) authentication
56 method with wpa_gui-qt4
59 * added support for EAP Sequences in EAP-FAST Phase 2
60 * added support for using TNC with EAP-FAST
61 * added driver_ps3 for the PS3 Linux wireless driver
62 * added support for optional cryptobinding with PEAPv0
63 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
64 allow fallback to full handshake if server rejects PAC-Opaque
65 * added fragmentation support for EAP-TNC
66 * added support for parsing PKCS #8 formatted private keys into the
67 internal TLS implementation (both PKCS #1 RSA key and PKCS #8
68 encapsulated RSA key can now be used)
69 * added option of using faster, but larger, routines in the internal
70 LibTomMath (for internal TLS implementation) to speed up DH and RSA
71 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
72 * fixed race condition between disassociation event and group key
73 handshake to avoid getting stuck in incorrect state [Bug 261]
74 * fixed opportunistic key caching (proactive_key_caching)
77 * removed 'nai' and 'eappsk' network configuration variables that were
78 previously used for configuring user identity and key for EAP-PSK,
79 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
80 replacement for 'nai' (if old configuration used a separate
81 'identity' value, that would now be configured as
82 'anonymous_identity'). 'password' field is now used as the
83 replacement for 'eappsk' (it can also be set using hexstring to
84 present random binary data)
85 * removed '-w' command line parameter (wait for interface to be added,
86 if needed); cleaner way of handling this functionality is to use an
87 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
88 when an interface is added
89 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
90 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
91 indicating when new scan results become available
92 * added new ctrl_iface command, BSS, to allow scan results to be
93 fetched without hitting the message size limits (this command
94 can be used to iterate through the scan results one BSS at the time)
95 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
96 attributes in EAP-SIM Start/Response when using fast reauthentication
97 * fixed EAPOL not to end up in infinite loop when processing dynamic
98 WEP keys with IEEE 802.1X
99 * fixed problems in getting NDIS events from WMI on Windows 2000
102 * added support for Makefile builds to include debug-log-to-a-file
103 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
104 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
105 lengths properly to avoid potential crash caused by invalid messages
106 * added data structure for storing allocated buffers (struct wpabuf);
107 this does not affect wpa_supplicant usage, but many of the APIs
108 changed and various interfaces (e.g., EAP) is not compatible with old
110 * added support for protecting EAP-AKA/Identity messages with
111 AT_CHECKCODE (optional feature in RFC 4187)
112 * added support for protected result indication with AT_RESULT_IND for
113 EAP-SIM and EAP-AKA (phase1="result_ind=1")
114 * added driver_wext workaround for race condition between scanning and
115 association with drivers that take very long time to scan all
116 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
117 using a longer hardcoded timeout for the scan if the driver supports
118 notifications for scan completion (SIOCGIWSCAN event); this helps,
119 e.g., in cases where wpa_supplicant and madwifi driver ended up in
120 loop where the driver did not even try to associate
121 * stop EAPOL timer tick when no timers are in use in order to reduce
122 power consumption (no need to wake up the process once per second)
124 * added support for privilege separation (run only minimal part of
125 wpa_supplicant functionality as root and rest as unprivileged,
126 non-root process); see 'Privilege separation' in README for details;
127 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
129 * changed scan results data structure to include all information
130 elements to make it easier to support new IEs; old get_scan_result()
131 driver_ops is still supported for backwards compatibility (results
132 are converted internally to the new format), but all drivers should
133 start using the new get_scan_results2() to make them more likely to
134 work with new features
135 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
136 application, i.e., it does not require Qt3Support anymore; Windows
137 binary of wpa_gui.exe is now from this directory and only requires
138 QtCore4.dll and QtGui4.dll libraries
139 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
140 available as a separate package to make wpa_gui installation easier:
141 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
142 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
143 only shared key/password authentication is supported in this version
146 * added support for configuring password as NtPasswordHash
147 (16-byte MD4 hash of password) in hash:<32 hex digits> format
148 * added support for fallback from abbreviated TLS handshake to
149 full handshake when using EAP-FAST (e.g., due to an expired
151 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
152 draft (draft-ietf-emu-eap-gpsk-07.txt)
153 * added support for drivers that take care of RSN 4-way handshake
154 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
155 WPA_ALG_PMK in set_key)
156 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
157 .config); this version supports only ap_scan=2 mode and allow the
158 driver to take care of the 4-way handshake
159 * fixed a buffer overflow in parsing TSF from scan results when using
160 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
162 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
163 * fixed an integer overflow issue in the ASN.1 parser used by the
164 (experimental) internal TLS implementation to avoid a potential
166 * fixed a race condition with -W option (wait for a control interface
167 monitor before starting) that could have caused the first messages to
169 * added support for processing TNCC-TNCS-Messages to report
170 recommendation (allow/none/isolate) when using TNC [Bug 243]
173 * added network configuration parameter 'frequency' for setting
174 initial channel for IBSS (adhoc) networks
175 * added experimental IEEE 802.11r/D6.0 support
176 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
177 * updated EAP-PSK to use the IANA-allocated EAP type 47
178 * fixed EAP-PAX key derivation
179 * fixed EAP-PSK bit ordering of the Flags field
180 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
181 tunnelled identity request (previously, the identifier from the outer
182 method was used, not the tunnelled identifier which could be
184 * added support for fragmentation of outer TLS packets during Phase 2
185 of EAP-PEAP/TTLS/FAST
186 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
187 * added support for EAP-FAST authentication with inner methods that
188 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
189 for PAC provisioning)
190 * added support for authenticated EAP-FAST provisioning
191 * added support for configuring maximum number of EAP-FAST PACs to
192 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
193 * added support for storing EAP-FAST PACs in binary format
194 (fast_pac_format=binary in phase1 string)
195 * fixed dbus ctrl_iface to validate message interface before
196 dispatching to avoid a possible segfault [Bug 190]
197 * fixed PeerKey key derivation to use the correct PRF label
198 * updated Windows binary build to link against OpenSSL 0.9.8d and
199 added support for EAP-FAST
200 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
201 draft (draft-ietf-emu-eap-gpsk-04.txt)
202 * fixed EAP-AKA Notification processing to allow Notification to be
203 processed after AKA Challenge response has been sent
204 * updated to use IEEE 802.11w/D2.0 for management frame protection
206 * fixed EAP-TTLS implementation not to crash on use of freed memory
207 if TLS library initialization fails
208 * added support for EAP-TNC (Trusted Network Connect)
209 (this version implements the EAP-TNC method and EAP-TTLS changes
210 needed to run two methods in sequence (IF-T) and the IF-IMC and
211 IF-TNCCS interfaces from TNCC)
214 * added experimental, integrated TLSv1 client implementation with the
215 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
216 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
217 .config); this can be useful, e.g., if the target system does not
218 have a suitable TLS library and a minimal code size is required
219 (total size of this internal TLS/crypto code is bit under 50 kB on
220 x86 and the crypto code is shared by rest of the supplicant so some
221 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
222 * removed STAKey handshake since PeerKey handshake has replaced it in
223 IEEE 802.11ma and there are no known deployments of STAKey
224 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
225 draft (draft-ietf-emu-eap-gpsk-01.txt)
226 * added preliminary implementation of IEEE 802.11w/D1.0 (management
228 (Note: this requires driver support to work properly.)
229 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
230 * fixed Windows named pipes ctrl_iface to not stop listening for
231 commands if client program opens a named pipe and closes it
232 immediately without sending a command
233 * fixed USIM PIN status determination for the case that PIN is not
234 needed (this allows EAP-AKA to be used with USIM cards that do not
236 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
237 be used with cards that do not support file selection based on
239 * added support for matching the subjectAltName of the authentication
240 server certificate against multiple name components (e.g.,
241 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
242 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
243 affects IEEE 802.1X with dynamic WEP keys)
244 * changed ctrl_iface network configuration 'get' operations to not
245 return password/key material; if these fields are requested, "*"
246 will be returned if the password/key is set, but the value of the
247 parameter is not exposed
250 * added support for building Windows version with UNICODE defined
251 (wide-char functions)
252 * driver_ndis: fixed static WEP configuration to avoid race condition
253 issues with some NDIS drivers between association and setting WEP
255 * driver_ndis: added validation for IELength value in scan results to
256 avoid crashes when using buggy NDIS drivers [Bug 165]
257 * fixed Release|Win32 target in the Visual Studio project files
258 (previously, only Debug|Win32 target was set properly)
259 * changed control interface API call wpa_ctrl_pending() to allow it to
260 return -1 on error (e.g., connection lost); control interface clients
261 will need to make sure that they verify that the value is indeed >0
262 when determining whether there are pending messages
263 * added an alternative control interface backend for Windows targets:
264 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
265 control interface mechanism for Windows builds (previously, UDP to
267 * changed ctrl_interface configuration for UNIX domain sockets:
268 - deprecated ctrl_interface_group variable (it may be removed in
270 - allow both directory and group be configured with ctrl_interface
271 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
272 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
273 case when group is not changed
274 * added support for controlling more than one interface per process in
276 * added a workaround for a case where the AP is using unknown address
277 (e.g., MAC address of the wired interface) as the source address for
278 EAPOL-Key frames; previously, that source address was used as the
279 destination for EAPOL-Key frames and in key derivation; now, BSSID is
280 used even if the source address does not match with it
281 (this resolves an interoperability issue with Thomson SpeedTouch 580)
282 * added a workaround for UDP-based control interface (which was used in
283 Windows builds before this release) to prevent packets with forged
284 addresses from being accepted as local control requests
285 * removed ndis_events.cpp and possibility of using external
286 ndis_events.exe; C version (ndis_events.c) is fully functional and
287 there is no desire to maintain two separate versions of this
289 * ndis_events: Changed NDIS event notification design to use WMI to
290 learn the adapter description through Win32_PnPEntity class; this
291 should fix some cases where the adapter name was not recognized
292 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
294 * fixed selection of the first network in ap_scan=2 mode; previously,
295 wpa_supplicant could get stuck in SCANNING state when only the first
296 network for enabled (e.g., after 'wpa_cli select_network 0')
297 * winsvc: added support for configuring ctrl_interface parameters in
298 registry (ctrl_interface string value in
299 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
300 required to enable control interface (previously, this was hardcoded
302 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
303 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
306 * fixed build with CONFIG_STAKEY=y [Bug 143]
307 * added support for doing MLME (IEEE 802.11 management frame
308 processing) in wpa_supplicant when using Devicescape IEEE 802.11
309 stack (wireless-dev.git tree)
310 * added a new network block configuration option, fragment_size, to
311 configure the maximum EAP fragment size
312 * driver_ndis: Disable WZC automatically for the selected interface to
313 avoid conflicts with two programs trying to control the radio; WZC
314 will be re-enabled (if it was enabled originally) when wpa_supplicant
316 * added an experimental TLSv1 client implementation
317 (CONFIG_TLS=internal) that can be used instead of an external TLS
318 library, e.g., to reduce total size requirement on systems that do
319 not include any TLS library by default (this is not yet complete;
320 basic functionality is there, but certificate validation is not yet
322 * added PeerKey handshake implementation for IEEE 802.11e
323 direct link setup (DLS) to replace STAKey handshake
324 * fixed WPA PSK update through ctrl_iface for the case where the old
325 PSK was derived from an ASCII passphrase and the new PSK is set as
326 a raw PSK (hex string)
327 * added new configuration option for identifying which network block
328 was used (id_str in wpa_supplicant.conf; included on
329 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
330 variable in wpa_cli action scripts; in addition WPA_ID variable is
331 set to the current unique identifier that wpa_supplicant assigned
332 automatically for the network and that can be used with
333 GET_NETWORK/SET_NETWORK ctrl_iface commands)
334 * wpa_cli action script is now called only when the connect/disconnect
335 status changes or when associating with a different network
336 * fixed configuration parser not to remove CCMP from group cipher list
337 if WPA-None (adhoc) is used (pairwise=NONE in that case)
338 * fixed integrated NDIS events processing not to hang the process due
339 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
340 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
341 draft-clancy-emu-eap-shared-secret-00.txt)
342 * added Microsoft Visual Studio 2005 solution and project files for
343 build wpa_supplicant for Windows (see vs2005 subdirectory)
344 * eloop_win: fixed unregistration of Windows events
345 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
346 at the end of RSN pre-authentication and added unregistration of
347 a Windows event to avoid getting eloop_win stuck with an invalid
349 * driver_ndis: added support for selecting AP based on BSSID
350 * added new environmental variable for wpa_cli action scripts:
351 WPA_CTRL_DIR is the current control interface directory
352 * driver_ndis: added support for using NDISUIO instead of WinPcap for
353 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
354 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
355 wpa_supplicant without requiring WinPcap; note that using NDISUIO
356 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
357 only one application to open the device
358 * changed NDIS driver naming to only include device GUID, e.g.,
359 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
360 specific \Device\NPF_ prefix before the GUID; the prefix is still
361 allowed for backwards compatibility, but it is not required anymore
362 when specifying the interface
363 * driver_ndis: re-initialize driver interface is the adapter is removed
364 and re-inserted [Bug 159]
365 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
366 big endian hosts [Bug 146]
369 * fixed EAP-GTC response to include correct user identity when run as
370 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
371 * driver_ndis: Fixed encryption mode configuration for unencrypted
372 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
373 refused to associate with open networks) [Bug 106]
374 * driver_ndis: use BSSID OID polling to detect when IBSS network is
375 formed even when ndis_events code is included since some NDIS drivers
376 do not generate media connect events in IBSS mode
377 * config_winreg: allow global ctrl_interface parameter to be configured
379 * config_winreg: added support for saving configuration data into
381 * added support for controlling network device operational state
382 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
383 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
384 that can use this information)
385 * driver_wext: added support for WE-21 change to SSID configuration
386 * driver_wext: fixed privacy configuration for static WEP keys mode
388 * added an optional driver_ops callback for MLME-SETPROTECTION.request
390 * added support for EAP-SAKE (no EAP method number allocated yet, so
391 this is using the same experimental type 255 as EAP-PSK)
392 * added support for dynamically loading EAP methods (.so files) instead
393 of requiring them to be statically linked in; this is disabled by
394 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
398 * do not try to use USIM APDUs when initializing PC/SC for SIM card
399 access for a network that has not enabled EAP-AKA
400 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
401 v0.5.1 due to the new support for expanded EAP types)
402 * added support for generating EAP Expanded Nak
403 * try to fetch scan results once before requesting new scan when
404 starting up in ap_scan=1 mode (this can speed up initial association
405 a lot with, e.g., madwifi-ng driver)
406 * added support for receiving EAPOL frames from a Linux bridge
407 interface (-bbr0 on command line)
408 * fixed EAPOL re-authentication for sessions that used PMKSA caching
409 * changed EAP method registration to use a dynamic list of methods
410 instead of a static list generated at build time
411 * fixed PMKSA cache deinitialization not to use freed memory when
412 removing PMKSA entries
413 * fixed a memory leak in EAP-TTLS re-authentication
414 * reject WPA/WPA2 message 3/4 if it does not include any valid
416 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
417 if the driver does not support SIOCSIWAUTH
420 * driver_test: added better support for multiple APs and STAs by using
421 a directory with sockets that include MAC address for each device in
422 the name (driver_param=test_dir=/tmp/test)
423 * added support for EAP expanded type (vendor specific EAP methods)
424 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
425 option can be changed if needed
426 * wpa_cli/wpa_gui: skip non-socket files in control directory when
427 using UNIX domain sockets; this avoids selecting an incorrect
428 interface (e.g., a PID file could be in this directory, even though
429 use of this directory for something else than socket files is not
431 * fixed TLS library deinitialization after RSN pre-authentication not
432 to disable TLS library for normal authentication
433 * driver_wext: Remove null-termination from SSID length if the driver
434 used it; some Linux drivers do this and they were causing problems in
435 wpa_supplicant not finding matching configuration block. This change
436 would break a case where the SSID actually ends in '\0', but that is
437 not likely to happen in real use.
438 * fixed PMKSA cache processing not to trigger deauthentication if the
439 current PMKSA cache entry is replaced with a valid new entry
440 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
441 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
444 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
445 * added experimental STAKey handshake implementation for IEEE 802.11e
446 direct link setup (DLS); note: this is disabled by default in both
447 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
449 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
450 decrypt AT_ENCR_DATA attributes correctly
451 * fixed EAP-AKA to allow resynchronization within the same session
452 * made code closer to ANSI C89 standard to make it easier to port to
453 other C libraries and compilers
454 * started moving operating system or C library specific functions into
455 wrapper functions defined in os.h and implemented in os_*.c to make
457 * wpa_supplicant can now be built with Microsoft Visual C++
458 (e.g., with the freely available Toolkit 2003 version or Visual
459 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
460 example makefile for nmake
461 * added support for using Windows registry for command line parameters
462 (CONFIG_MAIN=main_winsvc) and configuration data
463 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
464 contents; this version can be run both as a Windows service and as a
465 normal application; 'wpasvc.exe app' to start as applicant,
466 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
467 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
469 * made it possible to link ndis_events.exe functionality into
470 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
471 * added better support for multiple control interface backends
472 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
473 * fixed PC/SC code to use correct length for GSM AUTH command buffer
474 and to not use pioRecvPci with SCardTransmit() calls; these were not
475 causing visible problems with pcsc-lite, but Windows Winscard.dll
476 refused the previously used parameters; this fixes EAP-SIM and
477 EAP-AKA authentication using SIM/USIM card under Windows
478 * added new event loop implementation for Windows using
479 WaitForMultipleObject() instead of select() in order to allow waiting
480 for non-socket objects; this can be selected with
481 CONFIG_ELOOP=eloop_win in .config
482 * added support for selecting l2_packet implementation in .config
483 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
484 winpcap, freebsd, none)
485 * added new l2_packet implementation for WinPcap
486 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
487 reduce latency in EAPOL receive processing from about 100 ms to about
489 * added support for EAP-FAST key derivation using other ciphers than
490 RC4-128-SHA for authentication and AES128-SHA for provisioning
491 * added support for configuring CA certificate as DER file and as a
493 * fixed private key configuration as configuration blob and added
494 support for using PKCS#12 as a blob
495 * tls_gnutls: added support for using PKCS#12 files; added support for
497 * added support for loading trusted CA certificates from Windows
498 certificate store: ca_cert="cert_store://<name>", where <name> is
499 likely CA (Intermediate CA certificates) or ROOT (root certificates)
500 * added C version of ndis_events.cpp and made it possible to build this
501 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
502 easily on cross-compilation builds
503 * added wpasvc.exe into Windows binary release; this is an alternative
504 version of wpa_supplicant.exe with configuration backend using
505 Windows registry and with the entry point designed to run as a
507 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
508 wpasvc.exe and removed this additional tool from the Windows binary
509 release since it is not needed anymore
510 * load winscard.dll functions dynamically when building with MinGW
511 since MinGW does not yet include winscard library
513 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
514 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
515 and WinPcap to receive frames sent to PAE group address
516 * disable EAP state machine when IEEE 802.1X authentication is not used
517 in order to get rid of bogus "EAP failed" messages
518 * fixed OpenSSL error reporting to go through all pending errors to
519 avoid confusing reports of old errors being reported at later point
521 * fixed configuration file updating to not write empty variables
522 (e.g., proto or key_mgmt) that the file parser would not accept
523 * fixed ADD_NETWORK ctrl_iface command to use the same default values
524 for variables as empty network definitions read from config file
526 * fixed EAP state machine to not discard EAP-Failure messages in many
527 cases (e.g., during TLS handshake)
528 * fixed a infinite loop in private key reading if the configured file
529 cannot be parsed successfully
530 * driver_madwifi: added support for madwifi-ng
531 * wpa_gui: do not display password/PSK field contents
532 * wpa_gui: added CA certificate configuration
533 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
534 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
535 the new AP is using different WPA/RSN IE
536 * use longer timeout for IEEE 802.11 association to avoid problems with
537 drivers that may take more than five second to associate
540 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
541 RSN IE, but WPA IE would match with wpa_supplicant configuration
542 * added support for named configuration blobs in order to avoid having
543 to use file system for external files (e.g., certificates);
544 variables can be set to "blob://<blob name>" instead of file path to
545 use a named blob; supported fields: pac_file, client_cert,
547 * fixed RSN pre-authentication (it was broken in the clean up of WPA
548 state machine interface in v0.4.5)
549 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
550 sure the driver configures broadcast decryption correctly
551 * added ca_path (and ca_path2) configuration variables that can be used
552 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
553 system-wide trusted CA list
554 * added support for starting wpa_supplicant without a configuration
555 file (-C argument must be used to set ctrl_interface parameter for
556 this case; in addition, -p argument can be used to provide
557 driver_param; these new arguments can also be used with a
558 configuration to override the values from the configuration)
559 * added global control interface that can be optionally used for adding
560 and removing network interfaces dynamically (-g command line argument
561 for both wpa_supplicant and wpa_cli) without having to restart
562 wpa_supplicant process
564 - try to save configuration whenever something is modified
565 - added WEP key configuration
566 - added possibility to edit the current network configuration
567 * driver_ndis: fixed driver polling not to increase frequency on each
568 received EAPOL frame due to incorrectly cancelled timeout
569 * added simple configuration file examples (in examples subdirectory)
570 * fixed driver_wext.c to filter wireless events based on ifindex to
571 avoid interfaces receiving events from other interfaces
572 * delay sending initial EAPOL-Start couple of seconds to speed up
573 authentication for the most common case of Authenticator starting
574 EAP authentication immediately after association
577 * added a workaround for clearing keys with ndiswrapper to allow
578 roaming from WPA enabled AP to plaintext one
579 * added docbook documentation (doc/docbook) that can be used to
580 generate, e.g., man pages
581 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
582 PF_PACKET in order to prepare for network devices that do not use
583 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
584 * use receipt of EAPOL-Key frame as a lower layer success indication
585 for EAP state machine to allow recovery from dropped EAP-Success
587 * cleaned up internal EAPOL frame processing by not including link
588 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
589 header is added only when transmitted the frame; this makes it easier
590 to use wpa_supplicant on link layers that use different header than
592 * updated EAP-PSK to use draft 9 by default since this can now be
593 tested with hostapd; removed support for draft 3, including
594 server_nai configuration option from network blocks
595 * driver_wired: add PAE address to the multicast address list in order
596 to be able to receive EAPOL frames with drivers that do not include
597 these multicast addresses by default
598 * driver_wext: add support for WE-19
599 * added support for multiple configuration backends (CONFIG_BACKEND
600 option); currently, only 'file' is supported (i.e., the format used
601 in wpa_supplicant.conf)
602 * added support for updating configuration ('wpa_cli save_config');
603 this is disabled by default and can be enabled with global
604 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
605 and wpa_gui to store the configuration changes in a permanent store
606 * added GET_NETWORK ctrl_iface command
607 (e.g., 'wpa_cli get_network 0 ssid')
610 * replaced OpenSSL patch for EAP-FAST support
611 (openssl-tls-extensions.patch) with a more generic and correct
612 patch (the new patch is not compatible with the previous one, so the
613 OpenSSL library will need to be patched with the new patch in order
614 to be able to build wpa_supplicant with EAP-FAST support)
615 * added support for using Windows certificate store (through CryptoAPI)
616 for client certificate and private key operations (EAP-TLS)
617 (see wpa_supplicant.conf for more information on how to configure
618 this with private_key)
619 * ported wpa_gui to Windows
620 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
621 built with the open source version of the Qt4 for Windows
622 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
623 with drivers that do not support WPA
624 * ndis_events: fixed Windows 2000 support
625 * added support for enabling/disabling networks from the list of all
626 configured networks ('wpa_cli enable_network <network id>' and
627 'wpa_cli disable_network <network id>')
628 * added support for adding and removing network from the current
629 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
630 <network id>'); added networks are disabled by default and they can
631 be enabled with enable_network command once the configuration is done
632 for the new network; note: configuration file is not yet updated, so
633 these new networks are lost when wpa_supplicant is restarted
634 * added support for setting network configuration parameters through
635 the control interface, for example:
636 wpa_cli set_network 0 ssid "\"my network\""
637 * fixed parsing of strings that include both " and # within double
638 quoted area (e.g., "start"#end")
639 * added EAP workaround for PEAP session resumption: allow outer,
640 i.e., not tunneled, EAP-Success to terminate session since; this can
641 be disabled with eap_workaround=0
642 (this was allowed for PEAPv1 before, but now it is also allowed for
643 PEAPv0 since at least one RADIUS authentication server seems to be
644 doing this for PEAPv0, too)
645 * wpa_gui: added preliminary support for adding new networks to the
646 wpa_supplicant configuration (double click on the scan results to
647 open network configuration)
650 * removed interface for external EAPOL/EAP supplicant (e.g.,
651 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
652 anymore and is unlikely to be used by anyone
653 * driver_ndis: fixed WinPcap 3.0 support
654 * fixed build with CONFIG_DNET_PCAP=y on Linux
655 * l2_packet: moved different implementations into separate files
659 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
660 (note: ipw2100-1.1.0 is likely to require an update to work with
662 * added support for using ap_scan=2 mode with multiple network blocks;
663 wpa_supplicant will go through the networks one by one until the
664 driver reports a successful association; this uses the same order for
665 networks as scan_ssid=1 scans, i.e., the priority field is ignored
666 and the network block order in the file is used instead
667 * fixed a potential issue in RSN pre-authentication ending up using
668 freed memory if pre-authentication times out
669 * added support for matching alternative subject name extensions of the
670 authentication server certificate; new configuration variables
671 altsubject_match and altsubject_match2
672 * driver_ndis: added support for IEEE 802.1X authentication with wired
674 * added support for querying private key password (EAP-TLS) through the
675 control interface (wpa_cli/wpa_gui) if one is not included in the
677 * driver_broadcom: fixed couple of memory leaks in scan result
679 * EAP-PAX is now registered as EAP type 46
680 * fixed EAP-PAX MAC calculation
681 * fixed EAP-PAX CK and ICK key derivation
682 * added support for using password with EAP-PAX (as an alternative to
683 entering key with eappsk); SHA-1 hash of the password will be used as
685 * added support for arbitrary driver interface parameters through the
686 configuration file with a new driver_param field; this adds a new
687 driver_ops function set_param()
688 * added possibility to override l2_packet module with driver interface
689 API (new send_eapol handler); this can be used to implement driver
690 specific TX/RX functions for EAPOL frames
691 * fixed ctrl_interface_group processing for the case where gid is
692 entered as a number, not group name
693 * driver_test: added support for testing hostapd with wpa_supplicant
694 by using test driver interface without any kernel drivers or network
698 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
699 packets to be encrypted; this was apparently broken by the changed
700 ioctl order in v0.4.0
701 * driver_madwifi: added preliminary support for compiling against 'BSD'
702 branch of madwifi CVS tree
703 * added support for EAP-MSCHAPv2 password retries within the same EAP
704 authentication session
705 * added support for password changes with EAP-MSCHAPv2 (used when the
706 password has expired)
707 * added support for reading additional certificates from PKCS#12 files
708 and adding them to the certificate chain
709 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
711 * fixed a possible double free in EAP-TTLS fast-reauthentication when
712 identity or password is entered through control interface
713 * display EAP Notification messages to user through control interface
714 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
715 * added GUI version of wpa_cli, wpa_gui; this is not build
716 automatically with 'make'; use 'make wpa_gui' to build (this requires
717 Qt development tools)
718 * added 'disconnect' command to control interface for setting
719 wpa_supplicant in state where it will not associate before
720 'reassociate' command has been used
721 * added support for selecting a network from the list of all configured
722 networks ('wpa_cli select_network <network id>'; this disabled all
723 other networks; to re-enable, 'wpa_cli select_network any')
724 * added support for getting scan results through control interface
725 * added EAP workaround for PEAPv1 session resumption: allow outer,
726 i.e., not tunneled, EAP-Success to terminate session since; this can
727 be disabled with eap_workaround=0
729 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
730 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
731 used to reduce the size of the wpa_supplicant considerably if
732 debugging code is not needed
733 * fixed EAPOL-Key validation to drop packets with invalid Key Data
734 Length; such frames could have crashed wpa_supplicant due to buffer
736 * added support for wired authentication (IEEE 802.1X on wired
737 Ethernet); driver interface 'wired'
738 * obsoleted set_wpa() handler in the driver interface API (it can be
739 replaced by moving enable/disable functionality into init()/deinit())
740 (calls to set_wpa() are still present for backwards compatibility,
741 but they may be removed in the future)
742 * driver_madwifi: fixed association in plaintext mode
743 * modified the EAP workaround that accepts EAP-Success with incorrect
744 Identifier to be even less strict about verification in order to
745 interoperate with some authentication servers
746 * added support for sending TLS alerts
747 * added support for 'any' SSID wildcard; if ssid is not configured or
748 is set to an empty string, any SSID will be accepted for non-WPA AP
749 * added support for asking PIN (for SIM) from frontends (e.g.,
750 wpa_cli); if a PIN is needed, but not included in the configuration
751 file, a control interface request is sent and EAP processing is
752 delayed until the PIN is available
753 * added support for using external devices (e.g., a smartcard) for
754 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
755 new wpa_supplicant.conf variables:
756 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
757 - network: engine, engine_id, key_id
758 * added experimental support for EAP-PAX
759 * added monitor mode for wpa_cli (-a<path to a program to run>) that
760 allows external commands (e.g., shell scripts) to be run based on
761 wpa_supplicant events, e.g., when authentication has been completed
762 and data connection is ready; other related wpa_cli arguments:
763 -B (run in background), -P (write PID file); wpa_supplicant has a new
764 command line argument (-W) that can be used to make it wait until a
765 control interface command is received in order to avoid missing
767 * added support for opportunistic WPA2 PMKSA key caching (disabled by
768 default, can be enabled with proactive_key_caching=1)
769 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
770 Authenticator rejects PMKSA caching attempt and the driver is not
771 using assoc_info events
772 * added -P<pid file> argument for wpa_supplicant to write the current
773 process id into a file
775 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
776 * added new phase1 option parameter, include_tls_length=1, to force
777 wpa_supplicant to add TLS Message Length field to all TLS messages
778 even if the packet is not fragmented; this may be needed with some
779 authentication servers
780 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
781 using drivers that take care of AP selection (e.g., when using
783 * fixed reprocessing of pending request after ctrl_iface requests for
784 identity/password/otp
785 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
786 EAP-PEAP and EAP-TTLS
787 * all drivers using driver_wext: set interface up and select Managed
788 mode when starting wpa_supplicant; set interface down when exiting
789 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
790 ipw2100 and ipw2200; please note that this also changed the
791 configuration variable in .config to CONFIG_DRIVER_IPW
794 * fixed a busy loop introduced in v0.3.5 for scan result processing
795 when no matching AP is found
798 * added a workaround for an interoperability issue with a Cisco AP
800 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
801 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
802 retransmission of dropped frames)
803 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
804 (e.g., segfault when processing EAPOL-Key frames)
805 * fixed EAP workaround and fast reauthentication configuration for
806 RSN pre-authentication; previously these were disabled and
807 pre-authentication would fail if the used authentication server
808 requires EAP workarounds
809 * added support for blacklisting APs that fail or timeout
810 authentication in ap_scan=1 mode so that all APs are tried in cases
811 where the ones with strongest signal level are failing authentication
812 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
813 authentication attempt
814 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
815 in the previous authentication (previously, only Phase 1 success was
819 * added preliminary support for IBSS (ad-hoc) mode configuration
820 (mode=1 in network block); this included a new key_mgmt mode
821 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
822 key management; see wpa_supplicant.conf for more details and an
823 example on how to configure this (note: this is currently implemented
824 only for driver_hostapd.c, but the changes should be trivial to add
825 in associate() handler for other drivers, too (assuming the driver
827 * added preliminary port for native Windows (i.e., no cygwin) using
831 * added optional support for GNU Readline and History Libraries for
832 wpa_cli (CONFIG_READLINE)
833 * cleaned up EAP state machine <-> method interface and number of
834 small problems with error case processing not terminating on
835 EAP-Failure but waiting for timeout
836 * added couple of workarounds for interoperability issues with a
837 Cisco AP when using WPA2
838 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
839 Note: This requires a patch for openssl to add support for TLS
840 extensions and number of workarounds for operations without
841 certificates. Proof of concept type of experimental patch is
842 included in openssl-tls-extensions.patch.
845 * fixed private key loading for cases where passphrase is not set
846 * fixed Windows/cygwin L2 packet handler freeing; previous version
847 could cause a segfault when RSN pre-authentication was completed
848 * added support for PMKSA caching with drivers that generate RSN IEs
849 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
850 but similar code can be easily added to driver_ndiswrapper.c once
851 ndiswrapper gets full support for RSN PMKSA caching
852 * improved recovery from PMKID mismatches by requesting full EAP
853 authentication in case of failed PMKSA caching attempt
854 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
855 (this requires that ndis_events is ran while wpa_supplicant is
857 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
858 * added support for driver interfaces to replace the interface name
859 based on driver/OS specific mapping, e.g., in case of driver_ndis,
860 this allows the beginning of the adapter description to be used as
862 * added support for CR+LF (Windows-style) line ends in configuration
864 * driver_ndis: enable radio before starting scanning, disable radio
866 * modified association event handler to set portEnabled = FALSE before
867 clearing port Valid in order to reset EAP state machine and avoid
868 problems with new authentication getting ignored because of state
869 machines ending up in AUTHENTICATED/SUCCESS state based on old
871 * added support for driver events to add PMKID candidates in order to
872 allow drivers to give priority to most likely roaming candidates
873 * driver_hostap: moved PrivacyInvoked configuration to associate()
874 function so that this will not be set for plaintext connections
875 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
876 interface can distinguish plaintext and IEEE 802.1X (no WPA)
878 * fixed static WEP key configuration to use broadcast/default type for
879 all keys (previously, the default TX key was configured as pairwise/
881 * driver_ndis: added legacy WPA capability detection for non-WPA2
883 * added support for setting static WEP keys for IEEE 802.1X without
884 dynamic WEP keying (eapol_flags=0)
887 * added support for reading PKCS#12 (PFX) files (as a replacement for
888 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
889 * fixed compilation with CONFIG_PCSC=y
890 * added new ap_scan mode, ap_scan=2, for drivers that take care of
891 association, but need to be configured with security policy and SSID,
892 e.g., ndiswrapper and NDIS driver; this mode should allow such
893 drivers to work with hidden SSIDs and optimized roaming; when
894 ap_scan=2 is used, only the first network block in the configuration
895 file is used and this configuration should have explicit security
896 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
897 group, proto variables
898 * added experimental port of wpa_supplicant for Windows
899 - driver_ndis.c driver interface (NDIS OIDs)
900 - currently, this requires cygwin and WinPcap
901 - small utility, win_if_list, can be used to get interface name
902 * control interface can now be removed at build time; add
903 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
904 * optional Xsupplicant interface can now be removed at build time;
905 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
906 * added auth_alg to driver interface associate() parameters to make it
907 easier for drivers to configure authentication algorithm as part of
910 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
911 * driver_broadcom: added new driver interface for Broadcom wl.o driver
912 (a generic driver for Broadcom IEEE 802.11a/g cards)
913 * wpa_cli: fixed parsing of -p <path> command line argument
914 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
915 ACK, not tunneled EAP-Success (of which only the first byte was
916 actually send due to a bug in previous code); this seems to
917 interoperate with most RADIUS servers that implements PEAPv1
918 * PEAPv1: added support for terminating PEAP authentication on tunneled
919 EAP-Success message; this can be configured by adding
920 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
921 (some RADIUS servers require this whereas others require a tunneled
923 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
924 the old label for key derivation; previously, the default was 1,
925 but it looks like most existing PEAPv1 implementations use the old
926 label which is thus more suitable default option
927 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
928 * fixed parsing of wep_tx_keyidx
929 * added support for configuring list of allowed Phase 2 EAP types
930 (for both EAP-PEAP and EAP-TTLS) instead of only one type
931 * added support for configuring IEEE 802.11 authentication algorithm
932 (auth_alg; mainly for using Shared Key authentication with static
934 * added support for EAP-AKA (with UMTS SIM)
935 * fixed couple of errors in PCSC handling that could have caused
936 random-looking errors for EAP-SIM
937 * added support for EAP-SIM pseudonyms and fast re-authentication
938 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
940 * added support for EAP-SIM with two challanges
941 (phase1="sim_min_num_chal=3" can be used to require three challenges)
942 * added support for configuring DH/DSA parameters for an ephemeral DH
943 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
944 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
945 and optional DH key exchange to achieve forward secracy with RSA keys
946 * added support for matching subject of the authentication server
947 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
948 configuration variables subject_match and subject_match2
949 * changed SSID configuration in driver_wext.c (used by many driver
950 interfaces) to use ssid_len+1 as the length for SSID since some Linux
952 * fixed couple of unaligned reads in scan result parsing to fix WPA
953 connection on some platforms (e.g., ARM)
954 * added driver interface for Intel ipw2100 driver
955 * added support for LEAP with WPA
956 * added support for larger scan results report (old limit was 4 kB of
957 data, i.e., about 35 or so APs) when using Linux wireless extensions
959 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
960 only if there is a PMKSA cache entry for the current AP
961 * fixed error handling for case where reading of scan results fails:
962 must schedule a new scan or wpa_supplicant will remain waiting
964 * changed debug output to remove shared password/key material by
965 default; all key information can be included with -K command line
966 argument to match the previous behavior
967 * added support for timestamping debug log messages (disabled by
968 default, can be enabled with -t command line argument)
969 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
970 if keys are not configured to be used; this fixes IEEE 802.1X mode
971 with drivers that use this information to configure whether Privacy
972 bit can be in Beacon frames (e.g., ndiswrapper)
973 * avoid clearing driver keys if no keys have been configured since last
974 key clear request; this seems to improve reliability of group key
975 handshake for ndiswrapper & NDIS driver which seems to be suffering
976 of some kind of timing issue when the keys are cleared again after
978 * changed driver interface API:
979 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
980 version is being used (now, this is set to 2; previously, it was
982 - pass pointer to private data structure to all calls
983 - the new API is not backwards compatible; all in-tree driver
984 interfaces has been converted to the new API
985 * added support for controlling multiple interfaces (radios) per
986 wpa_supplicant process; each interface needs to be listed on the
987 command line (-c, -i, -D arguments) with -N as a separator
988 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
989 * added a workaround for EAP servers that incorrectly use same Id for
990 sequential EAP packets
991 * changed libpcap/libdnet configuration to use .config variable,
992 CONFIG_DNET_PCAP, instead of requiring Makefile modification
993 * improved downgrade attack detection in IE verification of msg 3/4:
994 verify both WPA and RSN IEs, if present, not only the selected one;
995 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
996 Probe Response frame, and RSN is enabled in wpa_supplicant
998 * fixed WPA msg 3/4 processing to allow Key Data field contain other
999 IEs than just one WPA IE
1000 * added support for FreeBSD and driver interface for the BSD net80211
1001 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
1002 required kernel mods have not yet been committed
1003 * made EAP workarounds configurable; enabled by default, can be
1004 disabled with network block option eap_workaround=0
1006 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
1007 * resolved couple of interoperability issues with EAP-PEAPv1 and
1008 Phase 2 (inner EAP) fragment reassembly
1009 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
1010 AP is using non-zero key index for the unicast key and key index zero
1011 for the broadcast key
1012 * driver_hostap: fixed IEEE 802.1X WEP key updates and
1013 re-authentication by allowing unencrypted EAPOL frames when not using
1015 * added a new driver interface, 'wext', which uses only standard,
1016 driver independent functionality in Linux wireless extensions;
1017 currently, this can be used only for non-WPA IEEE 802.1X mode, but
1018 eventually, this is to be extended to support full WPA/WPA2 once
1019 Linux wireless extensions get support for this
1020 * added support for mode in which the driver is responsible for AP
1021 scanning and selection; this is disabled by default and can be
1022 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
1023 this mode can be used, e.g., with generic 'wext' driver interface to
1024 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
1025 supporting wireless extensions.
1026 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
1027 operation with an AP that does not include SSID in the Beacon frames)
1028 * added support for new EAP authentication methods:
1029 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
1030 * added support for asking one-time-passwords from frontends (e.g.,
1031 wpa_cli); this 'otp' command works otherwise like 'password' command,
1032 but the password is used only once and the frontend will be asked for
1033 a new password whenever a request from authenticator requires a
1034 password; this can be used with both EAP-OTP and EAP-GTC
1035 * changed wpa_cli to automatically re-establish connection so that it
1036 does not need to be re-started when wpa_supplicant is terminated and
1038 * improved user data (identity/password/otp) requests through
1039 frontends: process pending EAPOL packets after getting new
1040 information so that full authentication does not need to be
1041 restarted; in addition, send pending requests again whenever a new
1042 frontend is attached
1043 * changed control frontends to use a new directory for socket files to
1044 make it easier for wpa_cli to automatically select between interfaces
1045 and to provide access control for the control interface;
1046 wpa_supplicant.conf: ctrl_interface is now a path
1047 (/var/run/wpa_supplicant is the recommended path) and
1048 ctrl_interface_group can be used to select which group gets access to
1049 the control interface;
1050 wpa_cli: by default, try to connect to the first interface available
1051 in /var/run/wpa_supplicant; this path can be overriden with -p option
1052 and an interface can be selected with -i option (i.e., in most common
1053 cases, wpa_cli does not need to get any arguments)
1054 * added support for LEAP
1055 * added driver interface for Linux ndiswrapper
1056 * added priority option for network blocks in the configuration file;
1057 this allows networks to be grouped based on priority (the scan
1058 results are searched for matches with network blocks in this order)
1061 * sort scan results to improve AP selection
1062 * fixed control interface socket removal for some error cases
1063 * improved scan requesting and authentication timeout
1064 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1066 * PEAP version can now be forced with phase1="peapver=<ver>"
1067 (mostly for testing; by default, the highest version supported by
1068 both the Supplicant and Authentication Server is selected
1070 * added support for madwifi driver (Atheros ar521x)
1071 * added a workaround for cases where AP sets Install Tx/Rx bit for
1072 WPA Group Key messages when pairwise keys are used (without this,
1073 the Group Key would be used for Tx and the AP would drop frames
1075 * added GSM SIM/USIM interface for GSM authentication algorithm for
1076 EAP-SIM; this requires pcsc-lite
1077 * added support for ATMEL AT76C5XXx driver
1078 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1079 does not include key data in the EAPOL-Key frame (i.e., part of
1080 EAP keying material is used as data encryption key)
1081 * added support for using plaintext and static WEP networks
1085 * added support for new EAP authentication methods:
1086 EAP-TTLS/EAP-MD5-Challenge
1088 EAP-TTLS/EAP-MSCHAPv2
1096 EAP-PEAP/MD5-Challenge
1098 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1099 * added support for anonymous identity (to be used when identity is
1100 sent in plaintext; real identity will be used within TLS protected
1101 tunnel (e.g., with EAP-TTLS)
1102 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1103 * added support for requesting identity and password information using
1104 control interface; in other words, the password for EAP-PEAP or
1105 EAP-TTLS does not need to be included in the configuration file since
1106 a frontand (e.g., wpa_cli) can ask it from the user
1107 * improved RSN pre-authentication to use a candidate list and process
1108 all candidates from each scan; not only one per scan
1109 * fixed RSN IE and WPA IE capabilities field parsing
1110 * ignore Tx bit in GTK IE when Pairwise keys are used
1111 * avoid making new scan requests during IEEE 802.1X negotiation
1112 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1113 with TLS support (this replaces the included implementation with
1114 library code to save about 8 kB since the library code is needed
1116 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1117 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1120 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1122 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1123 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1124 - EAP-MD5 (cannot be used with WPA-RADIUS)
1125 [draft-ietf-eap-rfc2284bis-09.txt]
1126 - EAP-TLS [RFC 2716]
1127 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1128 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1129 [draft-kamath-pppext-eap-mschapv2-00.txt]
1130 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1131 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1132 - new configuration file options: eap, identity, password, ca_cert,
1133 client_cert, privatekey, private_key_passwd
1134 - Xsupplicant is not required anymore, but it can be used by
1135 disabling the internal IEEE 802.1X Supplicant with -e command line
1137 - this code is not included in the default build; Makefile need to
1138 be edited for this (uncomment lines for selected functionality)
1139 - EAP-TLS and EAP-PEAP require openssl libraries
1140 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1141 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1142 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1143 EAPOL-Key frames instead of WPA key handshakes)
1144 * added support for IEEE 802.11i/RSN (WPA2)
1145 - improved PTK Key Handshake
1146 - PMKSA caching, pre-authentication
1147 * fixed wpa_supplicant to ignore possible extra data after WPA
1148 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1149 TPTK' error from message 3 of 4-Way Handshake in case the AP
1150 includes extra data after the EAPOL-Key)
1151 * added interface for external programs (frontends) to control
1153 - CLI example (wpa_cli) with interactive mode and command line
1155 - replaced SIGUSR1 status/statistics with the new control interface
1156 * made some feature compile time configurable
1157 - .config file for make
1158 - driver interfaces (hostap, hermes, ..)
1159 - EAPOL/EAP functions
1162 * Initial version of wpa_supplicant
