1 ChangeLog for wpa_supplicant
4 * cleaned up driver wrapper API (struct wpa_driver_ops); the new API
5 is not fully backwards compatible, so out-of-tree driver wrappers
6 will need modifications
7 * cleaned up various module interfaces
8 * merge hostapd and wpa_supplicant developers' documentation into a
10 * nl80211: use explicit deauthentication to clear cfg80211 state to
11 avoid issues when roaming between APs
12 * dbus: major design changes in the new D-Bus API
13 (fi.w1.wpa_supplicant1)
14 * nl80211: added support for IBSS networks
15 * added internal debugging mechanism with backtrace support and memory
16 allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y)
17 * added WPS ER unsubscription command to more cleanly unregister from
18 receiving UPnP events when ER is terminated
19 * cleaned up AP mode operations to avoid need for virtual driver_ops
21 * added BSS table to maintain more complete scan result information
22 over multiple scans (that may include only partial results)
23 * wpa_gui-qt4: update Peers dialog information more dynamically while
24 the dialog is kept open
25 * fixed PKCS#12 use with OpenSSL 1.0.0
26 * driver_wext: Added cfg80211-specific optimization to avoid some
27 unnecessary scans and to speed up association
30 * increased wpa_cli ping interval to 5 seconds and made this
31 configurable with a new command line options (-G<seconds>)
32 * fixed scan buffer processing with WEXT to handle up to 65535
33 byte result buffer (previously, limited to 32768 bytes)
34 * allow multiple driver wrappers to be specified on command line
35 (e.g., -Dnl80211,wext); the first one that is able to initialize the
36 interface will be used
37 * added support for multiple SSIDs per scan request to optimize
38 scan_ssid=1 operations in ap_scan=1 mode (i.e., search for hidden
39 SSIDs); this requires driver support and can currently be used only
41 * added support for WPS USBA out-of-band mechanism with USB Flash
42 Drives (UFD) (CONFIG_WPS_UFD=y)
43 * driver_ndis: add PAE group address to the multicast address list to
44 fix wired IEEE 802.1X authentication
45 * fixed IEEE 802.11r key derivation function to match with the standard
46 (note: this breaks interoperability with previous version) [Bug 303]
47 * added better support for drivers that allow separate authentication
48 and association commands (e.g., mac80211-based Linux drivers with
49 nl80211; SME in wpa_supplicant); this allows over-the-air FT protocol
50 to be used (IEEE 802.11r)
51 * fixed SHA-256 based key derivation function to match with the
52 standard when using CCMP (for IEEE 802.11r and IEEE 802.11w)
53 (note: this breaks interoperability with previous version) [Bug 307]
54 * use shared driver wrapper files with hostapd
55 * added AP mode functionality (CONFIG_AP=y) with mode=2 in the network
56 block; this can be used for open and WPA2-Personal networks
57 (optionally, with WPS); this links in parts of hostapd functionality
59 * wpa_gui-qt4: added new Peers dialog to show information about peers
60 (other devices, including APs and stations, etc. in the neighborhood)
61 * added support for WPS External Registrar functionality (configure APs
62 and enroll new devices); can be used with wpa_gui-qt4 Peers dialog
63 and wpa_cli commands wps_er_start, wps_er_stop, wps_er_pin,
64 wps_er_pbc, wps_er_learn
65 (this can also be used with a new 'none' driver wrapper if no
66 wireless device or IEEE 802.1X on wired is needed)
67 * driver_nl80211: multiple updates to provide support for new Linux
68 nl80211/mac80211 functionality
69 * updated management frame protection to use IEEE Std 802.11w-2009
70 * fixed number of small WPS issues and added workarounds to
71 interoperate with common deployed broken implementations
72 * added support for NFC out-of-band mechanism with WPS
73 * driver_ndis: fixed wired IEEE 802.1X authentication with PAE group
75 * added preliminary support for IEEE 802.11r RIC processing
76 * added support for specifying subset of enabled frequencies to scan
77 (scan_freq option in the network configuration block); this can speed
78 up scanning process considerably if it is known that only a small
79 subset of channels is actually used in the network (this is currently
80 supported only with -Dnl80211)
81 * added a workaround for race condition between receiving the
82 association event and the following EAPOL-Key
83 * added background scan and roaming infrastructure to allow
84 network-specific optimizations to be used to improve roaming within
86 * added new DBus interface (fi.w1.wpa_supplicant1)
89 * added support for Wi-Fi Protected Setup (WPS)
90 (wpa_supplicant can now be configured to act as a WPS Enrollee to
91 enroll credentials for a network using PIN and PBC methods; in
92 addition, wpa_supplicant can act as a wireless WPS Registrar to
93 configure an AP); WPS support can be enabled by adding CONFIG_WPS=y
94 into .config and setting the runtime configuration variables in
95 wpa_supplicant.conf (see WPS section in the example configuration
96 file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to
97 manage WPS negotiation; see README-WPS for more details
98 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
99 * added support for using driver_test over UDP socket
100 * fixed PEAPv0 Cryptobinding interoperability issue with Windows Server
101 2008 NPS; optional cryptobinding is now enabled (again) by default
102 * fixed PSK editing in wpa_gui
103 * changed EAP-GPSK to use the IANA assigned EAP method type 51
104 * added a Windows installer that includes WinPcap and all the needed
105 DLLs; in addition, it set up the registry automatically so that user
106 will only need start wpa_gui to get prompted to start the wpasvc
107 servide and add a new interface if needed through wpa_gui dialog
108 * updated management frame protection to use IEEE 802.11w/D7.0
111 * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
112 (can be used to simulate test SIM/USIM card with a known private key;
113 enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
114 and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
115 * added a new network configuration option, wpa_ptk_rekey, that can be
116 used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
117 against TKIP deficiencies
118 * added an optional mitigation mechanism for certain attacks against
119 TKIP by delaying Michael MIC error reports by a random amount of time
120 between 0 and 60 seconds; this can be enabled with a build option
121 CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
122 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
124 * updated OpenSSL code for EAP-FAST to use an updated version of the
125 session ticket overriding API that was included into the upstream
126 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
127 needed with that version anymore)
128 * updated userspace MLME instructions to match with the current Linux
129 mac80211 implementation; please also note that this can only be used
130 with driver_nl80211.c (the old code from driver_wext.c was removed)
131 * added support (Linux only) for RoboSwitch chipsets (often found in
132 consumer grade routers); driver interface 'roboswitch'
133 * fixed canceling of PMKSA caching when using drivers that generate
134 RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
138 * added support for SHA-256 as X.509 certificate digest when using the
139 internal X.509/TLSv1 implementation
140 * updated management frame protection to use IEEE 802.11w/D6.0
141 * added support for using SHA256-based stronger key derivation for WPA2
143 * fixed FT (IEEE 802.11r) authentication after a failed association to
145 * added support for configuring Phase 2 (inner/tunneled) authentication
146 method with wpa_gui-qt4
149 * added support for EAP Sequences in EAP-FAST Phase 2
150 * added support for using TNC with EAP-FAST
151 * added driver_ps3 for the PS3 Linux wireless driver
152 * added support for optional cryptobinding with PEAPv0
153 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
154 allow fallback to full handshake if server rejects PAC-Opaque
155 * added fragmentation support for EAP-TNC
156 * added support for parsing PKCS #8 formatted private keys into the
157 internal TLS implementation (both PKCS #1 RSA key and PKCS #8
158 encapsulated RSA key can now be used)
159 * added option of using faster, but larger, routines in the internal
160 LibTomMath (for internal TLS implementation) to speed up DH and RSA
161 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
162 * fixed race condition between disassociation event and group key
163 handshake to avoid getting stuck in incorrect state [Bug 261]
164 * fixed opportunistic key caching (proactive_key_caching)
167 * removed 'nai' and 'eappsk' network configuration variables that were
168 previously used for configuring user identity and key for EAP-PSK,
169 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
170 replacement for 'nai' (if old configuration used a separate
171 'identity' value, that would now be configured as
172 'anonymous_identity'). 'password' field is now used as the
173 replacement for 'eappsk' (it can also be set using hexstring to
174 present random binary data)
175 * removed '-w' command line parameter (wait for interface to be added,
176 if needed); cleaner way of handling this functionality is to use an
177 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
178 when an interface is added
179 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
180 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
181 indicating when new scan results become available
182 * added new ctrl_iface command, BSS, to allow scan results to be
183 fetched without hitting the message size limits (this command
184 can be used to iterate through the scan results one BSS at the time)
185 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
186 attributes in EAP-SIM Start/Response when using fast reauthentication
187 * fixed EAPOL not to end up in infinite loop when processing dynamic
188 WEP keys with IEEE 802.1X
189 * fixed problems in getting NDIS events from WMI on Windows 2000
192 * added support for Makefile builds to include debug-log-to-a-file
193 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
194 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
195 lengths properly to avoid potential crash caused by invalid messages
196 * added data structure for storing allocated buffers (struct wpabuf);
197 this does not affect wpa_supplicant usage, but many of the APIs
198 changed and various interfaces (e.g., EAP) is not compatible with old
200 * added support for protecting EAP-AKA/Identity messages with
201 AT_CHECKCODE (optional feature in RFC 4187)
202 * added support for protected result indication with AT_RESULT_IND for
203 EAP-SIM and EAP-AKA (phase1="result_ind=1")
204 * added driver_wext workaround for race condition between scanning and
205 association with drivers that take very long time to scan all
206 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
207 using a longer hardcoded timeout for the scan if the driver supports
208 notifications for scan completion (SIOCGIWSCAN event); this helps,
209 e.g., in cases where wpa_supplicant and madwifi driver ended up in
210 loop where the driver did not even try to associate
211 * stop EAPOL timer tick when no timers are in use in order to reduce
212 power consumption (no need to wake up the process once per second)
214 * added support for privilege separation (run only minimal part of
215 wpa_supplicant functionality as root and rest as unprivileged,
216 non-root process); see 'Privilege separation' in README for details;
217 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
219 * changed scan results data structure to include all information
220 elements to make it easier to support new IEs; old get_scan_result()
221 driver_ops is still supported for backwards compatibility (results
222 are converted internally to the new format), but all drivers should
223 start using the new get_scan_results2() to make them more likely to
224 work with new features
225 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
226 application, i.e., it does not require Qt3Support anymore; Windows
227 binary of wpa_gui.exe is now from this directory and only requires
228 QtCore4.dll and QtGui4.dll libraries
229 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
230 available as a separate package to make wpa_gui installation easier:
231 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
232 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
233 only shared key/password authentication is supported in this version
236 * added support for configuring password as NtPasswordHash
237 (16-byte MD4 hash of password) in hash:<32 hex digits> format
238 * added support for fallback from abbreviated TLS handshake to
239 full handshake when using EAP-FAST (e.g., due to an expired
241 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
242 draft (draft-ietf-emu-eap-gpsk-07.txt)
243 * added support for drivers that take care of RSN 4-way handshake
244 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
245 WPA_ALG_PMK in set_key)
246 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
247 .config); this version supports only ap_scan=2 mode and allow the
248 driver to take care of the 4-way handshake
249 * fixed a buffer overflow in parsing TSF from scan results when using
250 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
252 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
253 * fixed an integer overflow issue in the ASN.1 parser used by the
254 (experimental) internal TLS implementation to avoid a potential
256 * fixed a race condition with -W option (wait for a control interface
257 monitor before starting) that could have caused the first messages to
259 * added support for processing TNCC-TNCS-Messages to report
260 recommendation (allow/none/isolate) when using TNC [Bug 243]
263 * added network configuration parameter 'frequency' for setting
264 initial channel for IBSS (adhoc) networks
265 * added experimental IEEE 802.11r/D6.0 support
266 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
267 * updated EAP-PSK to use the IANA-allocated EAP type 47
268 * fixed EAP-PAX key derivation
269 * fixed EAP-PSK bit ordering of the Flags field
270 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
271 tunnelled identity request (previously, the identifier from the outer
272 method was used, not the tunnelled identifier which could be
274 * added support for fragmentation of outer TLS packets during Phase 2
275 of EAP-PEAP/TTLS/FAST
276 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
277 * added support for EAP-FAST authentication with inner methods that
278 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
279 for PAC provisioning)
280 * added support for authenticated EAP-FAST provisioning
281 * added support for configuring maximum number of EAP-FAST PACs to
282 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
283 * added support for storing EAP-FAST PACs in binary format
284 (fast_pac_format=binary in phase1 string)
285 * fixed dbus ctrl_iface to validate message interface before
286 dispatching to avoid a possible segfault [Bug 190]
287 * fixed PeerKey key derivation to use the correct PRF label
288 * updated Windows binary build to link against OpenSSL 0.9.8d and
289 added support for EAP-FAST
290 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
291 draft (draft-ietf-emu-eap-gpsk-04.txt)
292 * fixed EAP-AKA Notification processing to allow Notification to be
293 processed after AKA Challenge response has been sent
294 * updated to use IEEE 802.11w/D2.0 for management frame protection
296 * fixed EAP-TTLS implementation not to crash on use of freed memory
297 if TLS library initialization fails
298 * added support for EAP-TNC (Trusted Network Connect)
299 (this version implements the EAP-TNC method and EAP-TTLS changes
300 needed to run two methods in sequence (IF-T) and the IF-IMC and
301 IF-TNCCS interfaces from TNCC)
304 * added experimental, integrated TLSv1 client implementation with the
305 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
306 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
307 .config); this can be useful, e.g., if the target system does not
308 have a suitable TLS library and a minimal code size is required
309 (total size of this internal TLS/crypto code is bit under 50 kB on
310 x86 and the crypto code is shared by rest of the supplicant so some
311 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
312 * removed STAKey handshake since PeerKey handshake has replaced it in
313 IEEE 802.11ma and there are no known deployments of STAKey
314 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
315 draft (draft-ietf-emu-eap-gpsk-01.txt)
316 * added preliminary implementation of IEEE 802.11w/D1.0 (management
318 (Note: this requires driver support to work properly.)
319 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
320 * fixed Windows named pipes ctrl_iface to not stop listening for
321 commands if client program opens a named pipe and closes it
322 immediately without sending a command
323 * fixed USIM PIN status determination for the case that PIN is not
324 needed (this allows EAP-AKA to be used with USIM cards that do not
326 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
327 be used with cards that do not support file selection based on
329 * added support for matching the subjectAltName of the authentication
330 server certificate against multiple name components (e.g.,
331 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
332 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
333 affects IEEE 802.1X with dynamic WEP keys)
334 * changed ctrl_iface network configuration 'get' operations to not
335 return password/key material; if these fields are requested, "*"
336 will be returned if the password/key is set, but the value of the
337 parameter is not exposed
340 * added support for building Windows version with UNICODE defined
341 (wide-char functions)
342 * driver_ndis: fixed static WEP configuration to avoid race condition
343 issues with some NDIS drivers between association and setting WEP
345 * driver_ndis: added validation for IELength value in scan results to
346 avoid crashes when using buggy NDIS drivers [Bug 165]
347 * fixed Release|Win32 target in the Visual Studio project files
348 (previously, only Debug|Win32 target was set properly)
349 * changed control interface API call wpa_ctrl_pending() to allow it to
350 return -1 on error (e.g., connection lost); control interface clients
351 will need to make sure that they verify that the value is indeed >0
352 when determining whether there are pending messages
353 * added an alternative control interface backend for Windows targets:
354 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
355 control interface mechanism for Windows builds (previously, UDP to
357 * changed ctrl_interface configuration for UNIX domain sockets:
358 - deprecated ctrl_interface_group variable (it may be removed in
360 - allow both directory and group be configured with ctrl_interface
361 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
362 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
363 case when group is not changed
364 * added support for controlling more than one interface per process in
366 * added a workaround for a case where the AP is using unknown address
367 (e.g., MAC address of the wired interface) as the source address for
368 EAPOL-Key frames; previously, that source address was used as the
369 destination for EAPOL-Key frames and in key derivation; now, BSSID is
370 used even if the source address does not match with it
371 (this resolves an interoperability issue with Thomson SpeedTouch 580)
372 * added a workaround for UDP-based control interface (which was used in
373 Windows builds before this release) to prevent packets with forged
374 addresses from being accepted as local control requests
375 * removed ndis_events.cpp and possibility of using external
376 ndis_events.exe; C version (ndis_events.c) is fully functional and
377 there is no desire to maintain two separate versions of this
379 * ndis_events: Changed NDIS event notification design to use WMI to
380 learn the adapter description through Win32_PnPEntity class; this
381 should fix some cases where the adapter name was not recognized
382 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
384 * fixed selection of the first network in ap_scan=2 mode; previously,
385 wpa_supplicant could get stuck in SCANNING state when only the first
386 network for enabled (e.g., after 'wpa_cli select_network 0')
387 * winsvc: added support for configuring ctrl_interface parameters in
388 registry (ctrl_interface string value in
389 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
390 required to enable control interface (previously, this was hardcoded
392 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
393 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
396 * fixed build with CONFIG_STAKEY=y [Bug 143]
397 * added support for doing MLME (IEEE 802.11 management frame
398 processing) in wpa_supplicant when using Devicescape IEEE 802.11
399 stack (wireless-dev.git tree)
400 * added a new network block configuration option, fragment_size, to
401 configure the maximum EAP fragment size
402 * driver_ndis: Disable WZC automatically for the selected interface to
403 avoid conflicts with two programs trying to control the radio; WZC
404 will be re-enabled (if it was enabled originally) when wpa_supplicant
406 * added an experimental TLSv1 client implementation
407 (CONFIG_TLS=internal) that can be used instead of an external TLS
408 library, e.g., to reduce total size requirement on systems that do
409 not include any TLS library by default (this is not yet complete;
410 basic functionality is there, but certificate validation is not yet
412 * added PeerKey handshake implementation for IEEE 802.11e
413 direct link setup (DLS) to replace STAKey handshake
414 * fixed WPA PSK update through ctrl_iface for the case where the old
415 PSK was derived from an ASCII passphrase and the new PSK is set as
416 a raw PSK (hex string)
417 * added new configuration option for identifying which network block
418 was used (id_str in wpa_supplicant.conf; included on
419 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
420 variable in wpa_cli action scripts; in addition WPA_ID variable is
421 set to the current unique identifier that wpa_supplicant assigned
422 automatically for the network and that can be used with
423 GET_NETWORK/SET_NETWORK ctrl_iface commands)
424 * wpa_cli action script is now called only when the connect/disconnect
425 status changes or when associating with a different network
426 * fixed configuration parser not to remove CCMP from group cipher list
427 if WPA-None (adhoc) is used (pairwise=NONE in that case)
428 * fixed integrated NDIS events processing not to hang the process due
429 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
430 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
431 draft-clancy-emu-eap-shared-secret-00.txt)
432 * added Microsoft Visual Studio 2005 solution and project files for
433 build wpa_supplicant for Windows (see vs2005 subdirectory)
434 * eloop_win: fixed unregistration of Windows events
435 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
436 at the end of RSN pre-authentication and added unregistration of
437 a Windows event to avoid getting eloop_win stuck with an invalid
439 * driver_ndis: added support for selecting AP based on BSSID
440 * added new environmental variable for wpa_cli action scripts:
441 WPA_CTRL_DIR is the current control interface directory
442 * driver_ndis: added support for using NDISUIO instead of WinPcap for
443 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
444 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
445 wpa_supplicant without requiring WinPcap; note that using NDISUIO
446 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
447 only one application to open the device
448 * changed NDIS driver naming to only include device GUID, e.g.,
449 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
450 specific \Device\NPF_ prefix before the GUID; the prefix is still
451 allowed for backwards compatibility, but it is not required anymore
452 when specifying the interface
453 * driver_ndis: re-initialize driver interface is the adapter is removed
454 and re-inserted [Bug 159]
455 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
456 big endian hosts [Bug 146]
459 * fixed EAP-GTC response to include correct user identity when run as
460 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
461 * driver_ndis: Fixed encryption mode configuration for unencrypted
462 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
463 refused to associate with open networks) [Bug 106]
464 * driver_ndis: use BSSID OID polling to detect when IBSS network is
465 formed even when ndis_events code is included since some NDIS drivers
466 do not generate media connect events in IBSS mode
467 * config_winreg: allow global ctrl_interface parameter to be configured
469 * config_winreg: added support for saving configuration data into
471 * added support for controlling network device operational state
472 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
473 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
474 that can use this information)
475 * driver_wext: added support for WE-21 change to SSID configuration
476 * driver_wext: fixed privacy configuration for static WEP keys mode
478 * added an optional driver_ops callback for MLME-SETPROTECTION.request
480 * added support for EAP-SAKE (no EAP method number allocated yet, so
481 this is using the same experimental type 255 as EAP-PSK)
482 * added support for dynamically loading EAP methods (.so files) instead
483 of requiring them to be statically linked in; this is disabled by
484 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
488 * do not try to use USIM APDUs when initializing PC/SC for SIM card
489 access for a network that has not enabled EAP-AKA
490 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
491 v0.5.1 due to the new support for expanded EAP types)
492 * added support for generating EAP Expanded Nak
493 * try to fetch scan results once before requesting new scan when
494 starting up in ap_scan=1 mode (this can speed up initial association
495 a lot with, e.g., madwifi-ng driver)
496 * added support for receiving EAPOL frames from a Linux bridge
497 interface (-bbr0 on command line)
498 * fixed EAPOL re-authentication for sessions that used PMKSA caching
499 * changed EAP method registration to use a dynamic list of methods
500 instead of a static list generated at build time
501 * fixed PMKSA cache deinitialization not to use freed memory when
502 removing PMKSA entries
503 * fixed a memory leak in EAP-TTLS re-authentication
504 * reject WPA/WPA2 message 3/4 if it does not include any valid
506 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
507 if the driver does not support SIOCSIWAUTH
510 * driver_test: added better support for multiple APs and STAs by using
511 a directory with sockets that include MAC address for each device in
512 the name (driver_param=test_dir=/tmp/test)
513 * added support for EAP expanded type (vendor specific EAP methods)
514 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
515 option can be changed if needed
516 * wpa_cli/wpa_gui: skip non-socket files in control directory when
517 using UNIX domain sockets; this avoids selecting an incorrect
518 interface (e.g., a PID file could be in this directory, even though
519 use of this directory for something else than socket files is not
521 * fixed TLS library deinitialization after RSN pre-authentication not
522 to disable TLS library for normal authentication
523 * driver_wext: Remove null-termination from SSID length if the driver
524 used it; some Linux drivers do this and they were causing problems in
525 wpa_supplicant not finding matching configuration block. This change
526 would break a case where the SSID actually ends in '\0', but that is
527 not likely to happen in real use.
528 * fixed PMKSA cache processing not to trigger deauthentication if the
529 current PMKSA cache entry is replaced with a valid new entry
530 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
531 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
534 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
535 * added experimental STAKey handshake implementation for IEEE 802.11e
536 direct link setup (DLS); note: this is disabled by default in both
537 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
539 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
540 decrypt AT_ENCR_DATA attributes correctly
541 * fixed EAP-AKA to allow resynchronization within the same session
542 * made code closer to ANSI C89 standard to make it easier to port to
543 other C libraries and compilers
544 * started moving operating system or C library specific functions into
545 wrapper functions defined in os.h and implemented in os_*.c to make
547 * wpa_supplicant can now be built with Microsoft Visual C++
548 (e.g., with the freely available Toolkit 2003 version or Visual
549 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
550 example makefile for nmake
551 * added support for using Windows registry for command line parameters
552 (CONFIG_MAIN=main_winsvc) and configuration data
553 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
554 contents; this version can be run both as a Windows service and as a
555 normal application; 'wpasvc.exe app' to start as applicant,
556 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
557 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
559 * made it possible to link ndis_events.exe functionality into
560 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
561 * added better support for multiple control interface backends
562 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
563 * fixed PC/SC code to use correct length for GSM AUTH command buffer
564 and to not use pioRecvPci with SCardTransmit() calls; these were not
565 causing visible problems with pcsc-lite, but Windows Winscard.dll
566 refused the previously used parameters; this fixes EAP-SIM and
567 EAP-AKA authentication using SIM/USIM card under Windows
568 * added new event loop implementation for Windows using
569 WaitForMultipleObject() instead of select() in order to allow waiting
570 for non-socket objects; this can be selected with
571 CONFIG_ELOOP=eloop_win in .config
572 * added support for selecting l2_packet implementation in .config
573 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
574 winpcap, freebsd, none)
575 * added new l2_packet implementation for WinPcap
576 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
577 reduce latency in EAPOL receive processing from about 100 ms to about
579 * added support for EAP-FAST key derivation using other ciphers than
580 RC4-128-SHA for authentication and AES128-SHA for provisioning
581 * added support for configuring CA certificate as DER file and as a
583 * fixed private key configuration as configuration blob and added
584 support for using PKCS#12 as a blob
585 * tls_gnutls: added support for using PKCS#12 files; added support for
587 * added support for loading trusted CA certificates from Windows
588 certificate store: ca_cert="cert_store://<name>", where <name> is
589 likely CA (Intermediate CA certificates) or ROOT (root certificates)
590 * added C version of ndis_events.cpp and made it possible to build this
591 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
592 easily on cross-compilation builds
593 * added wpasvc.exe into Windows binary release; this is an alternative
594 version of wpa_supplicant.exe with configuration backend using
595 Windows registry and with the entry point designed to run as a
597 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
598 wpasvc.exe and removed this additional tool from the Windows binary
599 release since it is not needed anymore
600 * load winscard.dll functions dynamically when building with MinGW
601 since MinGW does not yet include winscard library
603 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
604 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
605 and WinPcap to receive frames sent to PAE group address
606 * disable EAP state machine when IEEE 802.1X authentication is not used
607 in order to get rid of bogus "EAP failed" messages
608 * fixed OpenSSL error reporting to go through all pending errors to
609 avoid confusing reports of old errors being reported at later point
611 * fixed configuration file updating to not write empty variables
612 (e.g., proto or key_mgmt) that the file parser would not accept
613 * fixed ADD_NETWORK ctrl_iface command to use the same default values
614 for variables as empty network definitions read from config file
616 * fixed EAP state machine to not discard EAP-Failure messages in many
617 cases (e.g., during TLS handshake)
618 * fixed a infinite loop in private key reading if the configured file
619 cannot be parsed successfully
620 * driver_madwifi: added support for madwifi-ng
621 * wpa_gui: do not display password/PSK field contents
622 * wpa_gui: added CA certificate configuration
623 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
624 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
625 the new AP is using different WPA/RSN IE
626 * use longer timeout for IEEE 802.11 association to avoid problems with
627 drivers that may take more than five second to associate
630 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
631 RSN IE, but WPA IE would match with wpa_supplicant configuration
632 * added support for named configuration blobs in order to avoid having
633 to use file system for external files (e.g., certificates);
634 variables can be set to "blob://<blob name>" instead of file path to
635 use a named blob; supported fields: pac_file, client_cert,
637 * fixed RSN pre-authentication (it was broken in the clean up of WPA
638 state machine interface in v0.4.5)
639 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
640 sure the driver configures broadcast decryption correctly
641 * added ca_path (and ca_path2) configuration variables that can be used
642 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
643 system-wide trusted CA list
644 * added support for starting wpa_supplicant without a configuration
645 file (-C argument must be used to set ctrl_interface parameter for
646 this case; in addition, -p argument can be used to provide
647 driver_param; these new arguments can also be used with a
648 configuration to override the values from the configuration)
649 * added global control interface that can be optionally used for adding
650 and removing network interfaces dynamically (-g command line argument
651 for both wpa_supplicant and wpa_cli) without having to restart
652 wpa_supplicant process
654 - try to save configuration whenever something is modified
655 - added WEP key configuration
656 - added possibility to edit the current network configuration
657 * driver_ndis: fixed driver polling not to increase frequency on each
658 received EAPOL frame due to incorrectly cancelled timeout
659 * added simple configuration file examples (in examples subdirectory)
660 * fixed driver_wext.c to filter wireless events based on ifindex to
661 avoid interfaces receiving events from other interfaces
662 * delay sending initial EAPOL-Start couple of seconds to speed up
663 authentication for the most common case of Authenticator starting
664 EAP authentication immediately after association
667 * added a workaround for clearing keys with ndiswrapper to allow
668 roaming from WPA enabled AP to plaintext one
669 * added docbook documentation (doc/docbook) that can be used to
670 generate, e.g., man pages
671 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
672 PF_PACKET in order to prepare for network devices that do not use
673 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
674 * use receipt of EAPOL-Key frame as a lower layer success indication
675 for EAP state machine to allow recovery from dropped EAP-Success
677 * cleaned up internal EAPOL frame processing by not including link
678 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
679 header is added only when transmitted the frame; this makes it easier
680 to use wpa_supplicant on link layers that use different header than
682 * updated EAP-PSK to use draft 9 by default since this can now be
683 tested with hostapd; removed support for draft 3, including
684 server_nai configuration option from network blocks
685 * driver_wired: add PAE address to the multicast address list in order
686 to be able to receive EAPOL frames with drivers that do not include
687 these multicast addresses by default
688 * driver_wext: add support for WE-19
689 * added support for multiple configuration backends (CONFIG_BACKEND
690 option); currently, only 'file' is supported (i.e., the format used
691 in wpa_supplicant.conf)
692 * added support for updating configuration ('wpa_cli save_config');
693 this is disabled by default and can be enabled with global
694 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
695 and wpa_gui to store the configuration changes in a permanent store
696 * added GET_NETWORK ctrl_iface command
697 (e.g., 'wpa_cli get_network 0 ssid')
700 * replaced OpenSSL patch for EAP-FAST support
701 (openssl-tls-extensions.patch) with a more generic and correct
702 patch (the new patch is not compatible with the previous one, so the
703 OpenSSL library will need to be patched with the new patch in order
704 to be able to build wpa_supplicant with EAP-FAST support)
705 * added support for using Windows certificate store (through CryptoAPI)
706 for client certificate and private key operations (EAP-TLS)
707 (see wpa_supplicant.conf for more information on how to configure
708 this with private_key)
709 * ported wpa_gui to Windows
710 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
711 built with the open source version of the Qt4 for Windows
712 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
713 with drivers that do not support WPA
714 * ndis_events: fixed Windows 2000 support
715 * added support for enabling/disabling networks from the list of all
716 configured networks ('wpa_cli enable_network <network id>' and
717 'wpa_cli disable_network <network id>')
718 * added support for adding and removing network from the current
719 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
720 <network id>'); added networks are disabled by default and they can
721 be enabled with enable_network command once the configuration is done
722 for the new network; note: configuration file is not yet updated, so
723 these new networks are lost when wpa_supplicant is restarted
724 * added support for setting network configuration parameters through
725 the control interface, for example:
726 wpa_cli set_network 0 ssid "\"my network\""
727 * fixed parsing of strings that include both " and # within double
728 quoted area (e.g., "start"#end")
729 * added EAP workaround for PEAP session resumption: allow outer,
730 i.e., not tunneled, EAP-Success to terminate session since; this can
731 be disabled with eap_workaround=0
732 (this was allowed for PEAPv1 before, but now it is also allowed for
733 PEAPv0 since at least one RADIUS authentication server seems to be
734 doing this for PEAPv0, too)
735 * wpa_gui: added preliminary support for adding new networks to the
736 wpa_supplicant configuration (double click on the scan results to
737 open network configuration)
740 * removed interface for external EAPOL/EAP supplicant (e.g.,
741 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
742 anymore and is unlikely to be used by anyone
743 * driver_ndis: fixed WinPcap 3.0 support
744 * fixed build with CONFIG_DNET_PCAP=y on Linux
745 * l2_packet: moved different implementations into separate files
749 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
750 (note: ipw2100-1.1.0 is likely to require an update to work with
752 * added support for using ap_scan=2 mode with multiple network blocks;
753 wpa_supplicant will go through the networks one by one until the
754 driver reports a successful association; this uses the same order for
755 networks as scan_ssid=1 scans, i.e., the priority field is ignored
756 and the network block order in the file is used instead
757 * fixed a potential issue in RSN pre-authentication ending up using
758 freed memory if pre-authentication times out
759 * added support for matching alternative subject name extensions of the
760 authentication server certificate; new configuration variables
761 altsubject_match and altsubject_match2
762 * driver_ndis: added support for IEEE 802.1X authentication with wired
764 * added support for querying private key password (EAP-TLS) through the
765 control interface (wpa_cli/wpa_gui) if one is not included in the
767 * driver_broadcom: fixed couple of memory leaks in scan result
769 * EAP-PAX is now registered as EAP type 46
770 * fixed EAP-PAX MAC calculation
771 * fixed EAP-PAX CK and ICK key derivation
772 * added support for using password with EAP-PAX (as an alternative to
773 entering key with eappsk); SHA-1 hash of the password will be used as
775 * added support for arbitrary driver interface parameters through the
776 configuration file with a new driver_param field; this adds a new
777 driver_ops function set_param()
778 * added possibility to override l2_packet module with driver interface
779 API (new send_eapol handler); this can be used to implement driver
780 specific TX/RX functions for EAPOL frames
781 * fixed ctrl_interface_group processing for the case where gid is
782 entered as a number, not group name
783 * driver_test: added support for testing hostapd with wpa_supplicant
784 by using test driver interface without any kernel drivers or network
788 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
789 packets to be encrypted; this was apparently broken by the changed
790 ioctl order in v0.4.0
791 * driver_madwifi: added preliminary support for compiling against 'BSD'
792 branch of madwifi CVS tree
793 * added support for EAP-MSCHAPv2 password retries within the same EAP
794 authentication session
795 * added support for password changes with EAP-MSCHAPv2 (used when the
796 password has expired)
797 * added support for reading additional certificates from PKCS#12 files
798 and adding them to the certificate chain
799 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
801 * fixed a possible double free in EAP-TTLS fast-reauthentication when
802 identity or password is entered through control interface
803 * display EAP Notification messages to user through control interface
804 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
805 * added GUI version of wpa_cli, wpa_gui; this is not build
806 automatically with 'make'; use 'make wpa_gui' to build (this requires
807 Qt development tools)
808 * added 'disconnect' command to control interface for setting
809 wpa_supplicant in state where it will not associate before
810 'reassociate' command has been used
811 * added support for selecting a network from the list of all configured
812 networks ('wpa_cli select_network <network id>'; this disabled all
813 other networks; to re-enable, 'wpa_cli select_network any')
814 * added support for getting scan results through control interface
815 * added EAP workaround for PEAPv1 session resumption: allow outer,
816 i.e., not tunneled, EAP-Success to terminate session since; this can
817 be disabled with eap_workaround=0
819 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
820 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
821 used to reduce the size of the wpa_supplicant considerably if
822 debugging code is not needed
823 * fixed EAPOL-Key validation to drop packets with invalid Key Data
824 Length; such frames could have crashed wpa_supplicant due to buffer
826 * added support for wired authentication (IEEE 802.1X on wired
827 Ethernet); driver interface 'wired'
828 * obsoleted set_wpa() handler in the driver interface API (it can be
829 replaced by moving enable/disable functionality into init()/deinit())
830 (calls to set_wpa() are still present for backwards compatibility,
831 but they may be removed in the future)
832 * driver_madwifi: fixed association in plaintext mode
833 * modified the EAP workaround that accepts EAP-Success with incorrect
834 Identifier to be even less strict about verification in order to
835 interoperate with some authentication servers
836 * added support for sending TLS alerts
837 * added support for 'any' SSID wildcard; if ssid is not configured or
838 is set to an empty string, any SSID will be accepted for non-WPA AP
839 * added support for asking PIN (for SIM) from frontends (e.g.,
840 wpa_cli); if a PIN is needed, but not included in the configuration
841 file, a control interface request is sent and EAP processing is
842 delayed until the PIN is available
843 * added support for using external devices (e.g., a smartcard) for
844 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
845 new wpa_supplicant.conf variables:
846 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
847 - network: engine, engine_id, key_id
848 * added experimental support for EAP-PAX
849 * added monitor mode for wpa_cli (-a<path to a program to run>) that
850 allows external commands (e.g., shell scripts) to be run based on
851 wpa_supplicant events, e.g., when authentication has been completed
852 and data connection is ready; other related wpa_cli arguments:
853 -B (run in background), -P (write PID file); wpa_supplicant has a new
854 command line argument (-W) that can be used to make it wait until a
855 control interface command is received in order to avoid missing
857 * added support for opportunistic WPA2 PMKSA key caching (disabled by
858 default, can be enabled with proactive_key_caching=1)
859 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
860 Authenticator rejects PMKSA caching attempt and the driver is not
861 using assoc_info events
862 * added -P<pid file> argument for wpa_supplicant to write the current
863 process id into a file
865 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
866 * added new phase1 option parameter, include_tls_length=1, to force
867 wpa_supplicant to add TLS Message Length field to all TLS messages
868 even if the packet is not fragmented; this may be needed with some
869 authentication servers
870 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
871 using drivers that take care of AP selection (e.g., when using
873 * fixed reprocessing of pending request after ctrl_iface requests for
874 identity/password/otp
875 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
876 EAP-PEAP and EAP-TTLS
877 * all drivers using driver_wext: set interface up and select Managed
878 mode when starting wpa_supplicant; set interface down when exiting
879 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
880 ipw2100 and ipw2200; please note that this also changed the
881 configuration variable in .config to CONFIG_DRIVER_IPW
884 * fixed a busy loop introduced in v0.3.5 for scan result processing
885 when no matching AP is found
888 * added a workaround for an interoperability issue with a Cisco AP
890 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
891 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
892 retransmission of dropped frames)
893 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
894 (e.g., segfault when processing EAPOL-Key frames)
895 * fixed EAP workaround and fast reauthentication configuration for
896 RSN pre-authentication; previously these were disabled and
897 pre-authentication would fail if the used authentication server
898 requires EAP workarounds
899 * added support for blacklisting APs that fail or timeout
900 authentication in ap_scan=1 mode so that all APs are tried in cases
901 where the ones with strongest signal level are failing authentication
902 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
903 authentication attempt
904 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
905 in the previous authentication (previously, only Phase 1 success was
909 * added preliminary support for IBSS (ad-hoc) mode configuration
910 (mode=1 in network block); this included a new key_mgmt mode
911 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
912 key management; see wpa_supplicant.conf for more details and an
913 example on how to configure this (note: this is currently implemented
914 only for driver_hostapd.c, but the changes should be trivial to add
915 in associate() handler for other drivers, too (assuming the driver
917 * added preliminary port for native Windows (i.e., no cygwin) using
921 * added optional support for GNU Readline and History Libraries for
922 wpa_cli (CONFIG_READLINE)
923 * cleaned up EAP state machine <-> method interface and number of
924 small problems with error case processing not terminating on
925 EAP-Failure but waiting for timeout
926 * added couple of workarounds for interoperability issues with a
927 Cisco AP when using WPA2
928 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
929 Note: This requires a patch for openssl to add support for TLS
930 extensions and number of workarounds for operations without
931 certificates. Proof of concept type of experimental patch is
932 included in openssl-tls-extensions.patch.
935 * fixed private key loading for cases where passphrase is not set
936 * fixed Windows/cygwin L2 packet handler freeing; previous version
937 could cause a segfault when RSN pre-authentication was completed
938 * added support for PMKSA caching with drivers that generate RSN IEs
939 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
940 but similar code can be easily added to driver_ndiswrapper.c once
941 ndiswrapper gets full support for RSN PMKSA caching
942 * improved recovery from PMKID mismatches by requesting full EAP
943 authentication in case of failed PMKSA caching attempt
944 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
945 (this requires that ndis_events is ran while wpa_supplicant is
947 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
948 * added support for driver interfaces to replace the interface name
949 based on driver/OS specific mapping, e.g., in case of driver_ndis,
950 this allows the beginning of the adapter description to be used as
952 * added support for CR+LF (Windows-style) line ends in configuration
954 * driver_ndis: enable radio before starting scanning, disable radio
956 * modified association event handler to set portEnabled = FALSE before
957 clearing port Valid in order to reset EAP state machine and avoid
958 problems with new authentication getting ignored because of state
959 machines ending up in AUTHENTICATED/SUCCESS state based on old
961 * added support for driver events to add PMKID candidates in order to
962 allow drivers to give priority to most likely roaming candidates
963 * driver_hostap: moved PrivacyInvoked configuration to associate()
964 function so that this will not be set for plaintext connections
965 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
966 interface can distinguish plaintext and IEEE 802.1X (no WPA)
968 * fixed static WEP key configuration to use broadcast/default type for
969 all keys (previously, the default TX key was configured as pairwise/
971 * driver_ndis: added legacy WPA capability detection for non-WPA2
973 * added support for setting static WEP keys for IEEE 802.1X without
974 dynamic WEP keying (eapol_flags=0)
977 * added support for reading PKCS#12 (PFX) files (as a replacement for
978 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
979 * fixed compilation with CONFIG_PCSC=y
980 * added new ap_scan mode, ap_scan=2, for drivers that take care of
981 association, but need to be configured with security policy and SSID,
982 e.g., ndiswrapper and NDIS driver; this mode should allow such
983 drivers to work with hidden SSIDs and optimized roaming; when
984 ap_scan=2 is used, only the first network block in the configuration
985 file is used and this configuration should have explicit security
986 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
987 group, proto variables
988 * added experimental port of wpa_supplicant for Windows
989 - driver_ndis.c driver interface (NDIS OIDs)
990 - currently, this requires cygwin and WinPcap
991 - small utility, win_if_list, can be used to get interface name
992 * control interface can now be removed at build time; add
993 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
994 * optional Xsupplicant interface can now be removed at build time;
995 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
996 * added auth_alg to driver interface associate() parameters to make it
997 easier for drivers to configure authentication algorithm as part of
1000 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
1001 * driver_broadcom: added new driver interface for Broadcom wl.o driver
1002 (a generic driver for Broadcom IEEE 802.11a/g cards)
1003 * wpa_cli: fixed parsing of -p <path> command line argument
1004 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
1005 ACK, not tunneled EAP-Success (of which only the first byte was
1006 actually send due to a bug in previous code); this seems to
1007 interoperate with most RADIUS servers that implements PEAPv1
1008 * PEAPv1: added support for terminating PEAP authentication on tunneled
1009 EAP-Success message; this can be configured by adding
1010 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
1011 (some RADIUS servers require this whereas others require a tunneled
1013 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
1014 the old label for key derivation; previously, the default was 1,
1015 but it looks like most existing PEAPv1 implementations use the old
1016 label which is thus more suitable default option
1017 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
1018 * fixed parsing of wep_tx_keyidx
1019 * added support for configuring list of allowed Phase 2 EAP types
1020 (for both EAP-PEAP and EAP-TTLS) instead of only one type
1021 * added support for configuring IEEE 802.11 authentication algorithm
1022 (auth_alg; mainly for using Shared Key authentication with static
1024 * added support for EAP-AKA (with UMTS SIM)
1025 * fixed couple of errors in PCSC handling that could have caused
1026 random-looking errors for EAP-SIM
1027 * added support for EAP-SIM pseudonyms and fast re-authentication
1028 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
1030 * added support for EAP-SIM with two challanges
1031 (phase1="sim_min_num_chal=3" can be used to require three challenges)
1032 * added support for configuring DH/DSA parameters for an ephemeral DH
1033 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
1034 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
1035 and optional DH key exchange to achieve forward secracy with RSA keys
1036 * added support for matching subject of the authentication server
1037 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
1038 configuration variables subject_match and subject_match2
1039 * changed SSID configuration in driver_wext.c (used by many driver
1040 interfaces) to use ssid_len+1 as the length for SSID since some Linux
1042 * fixed couple of unaligned reads in scan result parsing to fix WPA
1043 connection on some platforms (e.g., ARM)
1044 * added driver interface for Intel ipw2100 driver
1045 * added support for LEAP with WPA
1046 * added support for larger scan results report (old limit was 4 kB of
1047 data, i.e., about 35 or so APs) when using Linux wireless extensions
1049 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
1050 only if there is a PMKSA cache entry for the current AP
1051 * fixed error handling for case where reading of scan results fails:
1052 must schedule a new scan or wpa_supplicant will remain waiting
1054 * changed debug output to remove shared password/key material by
1055 default; all key information can be included with -K command line
1056 argument to match the previous behavior
1057 * added support for timestamping debug log messages (disabled by
1058 default, can be enabled with -t command line argument)
1059 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
1060 if keys are not configured to be used; this fixes IEEE 802.1X mode
1061 with drivers that use this information to configure whether Privacy
1062 bit can be in Beacon frames (e.g., ndiswrapper)
1063 * avoid clearing driver keys if no keys have been configured since last
1064 key clear request; this seems to improve reliability of group key
1065 handshake for ndiswrapper & NDIS driver which seems to be suffering
1066 of some kind of timing issue when the keys are cleared again after
1068 * changed driver interface API:
1069 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
1070 version is being used (now, this is set to 2; previously, it was
1072 - pass pointer to private data structure to all calls
1073 - the new API is not backwards compatible; all in-tree driver
1074 interfaces has been converted to the new API
1075 * added support for controlling multiple interfaces (radios) per
1076 wpa_supplicant process; each interface needs to be listed on the
1077 command line (-c, -i, -D arguments) with -N as a separator
1078 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
1079 * added a workaround for EAP servers that incorrectly use same Id for
1080 sequential EAP packets
1081 * changed libpcap/libdnet configuration to use .config variable,
1082 CONFIG_DNET_PCAP, instead of requiring Makefile modification
1083 * improved downgrade attack detection in IE verification of msg 3/4:
1084 verify both WPA and RSN IEs, if present, not only the selected one;
1085 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
1086 Probe Response frame, and RSN is enabled in wpa_supplicant
1088 * fixed WPA msg 3/4 processing to allow Key Data field contain other
1089 IEs than just one WPA IE
1090 * added support for FreeBSD and driver interface for the BSD net80211
1091 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
1092 required kernel mods have not yet been committed
1093 * made EAP workarounds configurable; enabled by default, can be
1094 disabled with network block option eap_workaround=0
1096 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
1097 * resolved couple of interoperability issues with EAP-PEAPv1 and
1098 Phase 2 (inner EAP) fragment reassembly
1099 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
1100 AP is using non-zero key index for the unicast key and key index zero
1101 for the broadcast key
1102 * driver_hostap: fixed IEEE 802.1X WEP key updates and
1103 re-authentication by allowing unencrypted EAPOL frames when not using
1105 * added a new driver interface, 'wext', which uses only standard,
1106 driver independent functionality in Linux wireless extensions;
1107 currently, this can be used only for non-WPA IEEE 802.1X mode, but
1108 eventually, this is to be extended to support full WPA/WPA2 once
1109 Linux wireless extensions get support for this
1110 * added support for mode in which the driver is responsible for AP
1111 scanning and selection; this is disabled by default and can be
1112 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
1113 this mode can be used, e.g., with generic 'wext' driver interface to
1114 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
1115 supporting wireless extensions.
1116 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
1117 operation with an AP that does not include SSID in the Beacon frames)
1118 * added support for new EAP authentication methods:
1119 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
1120 * added support for asking one-time-passwords from frontends (e.g.,
1121 wpa_cli); this 'otp' command works otherwise like 'password' command,
1122 but the password is used only once and the frontend will be asked for
1123 a new password whenever a request from authenticator requires a
1124 password; this can be used with both EAP-OTP and EAP-GTC
1125 * changed wpa_cli to automatically re-establish connection so that it
1126 does not need to be re-started when wpa_supplicant is terminated and
1128 * improved user data (identity/password/otp) requests through
1129 frontends: process pending EAPOL packets after getting new
1130 information so that full authentication does not need to be
1131 restarted; in addition, send pending requests again whenever a new
1132 frontend is attached
1133 * changed control frontends to use a new directory for socket files to
1134 make it easier for wpa_cli to automatically select between interfaces
1135 and to provide access control for the control interface;
1136 wpa_supplicant.conf: ctrl_interface is now a path
1137 (/var/run/wpa_supplicant is the recommended path) and
1138 ctrl_interface_group can be used to select which group gets access to
1139 the control interface;
1140 wpa_cli: by default, try to connect to the first interface available
1141 in /var/run/wpa_supplicant; this path can be overriden with -p option
1142 and an interface can be selected with -i option (i.e., in most common
1143 cases, wpa_cli does not need to get any arguments)
1144 * added support for LEAP
1145 * added driver interface for Linux ndiswrapper
1146 * added priority option for network blocks in the configuration file;
1147 this allows networks to be grouped based on priority (the scan
1148 results are searched for matches with network blocks in this order)
1151 * sort scan results to improve AP selection
1152 * fixed control interface socket removal for some error cases
1153 * improved scan requesting and authentication timeout
1154 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1156 * PEAP version can now be forced with phase1="peapver=<ver>"
1157 (mostly for testing; by default, the highest version supported by
1158 both the Supplicant and Authentication Server is selected
1160 * added support for madwifi driver (Atheros ar521x)
1161 * added a workaround for cases where AP sets Install Tx/Rx bit for
1162 WPA Group Key messages when pairwise keys are used (without this,
1163 the Group Key would be used for Tx and the AP would drop frames
1165 * added GSM SIM/USIM interface for GSM authentication algorithm for
1166 EAP-SIM; this requires pcsc-lite
1167 * added support for ATMEL AT76C5XXx driver
1168 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1169 does not include key data in the EAPOL-Key frame (i.e., part of
1170 EAP keying material is used as data encryption key)
1171 * added support for using plaintext and static WEP networks
1175 * added support for new EAP authentication methods:
1176 EAP-TTLS/EAP-MD5-Challenge
1178 EAP-TTLS/EAP-MSCHAPv2
1186 EAP-PEAP/MD5-Challenge
1188 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1189 * added support for anonymous identity (to be used when identity is
1190 sent in plaintext; real identity will be used within TLS protected
1191 tunnel (e.g., with EAP-TTLS)
1192 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1193 * added support for requesting identity and password information using
1194 control interface; in other words, the password for EAP-PEAP or
1195 EAP-TTLS does not need to be included in the configuration file since
1196 a frontand (e.g., wpa_cli) can ask it from the user
1197 * improved RSN pre-authentication to use a candidate list and process
1198 all candidates from each scan; not only one per scan
1199 * fixed RSN IE and WPA IE capabilities field parsing
1200 * ignore Tx bit in GTK IE when Pairwise keys are used
1201 * avoid making new scan requests during IEEE 802.1X negotiation
1202 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1203 with TLS support (this replaces the included implementation with
1204 library code to save about 8 kB since the library code is needed
1206 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1207 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1210 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1212 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1213 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1214 - EAP-MD5 (cannot be used with WPA-RADIUS)
1215 [draft-ietf-eap-rfc2284bis-09.txt]
1216 - EAP-TLS [RFC 2716]
1217 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1218 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1219 [draft-kamath-pppext-eap-mschapv2-00.txt]
1220 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1221 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1222 - new configuration file options: eap, identity, password, ca_cert,
1223 client_cert, privatekey, private_key_passwd
1224 - Xsupplicant is not required anymore, but it can be used by
1225 disabling the internal IEEE 802.1X Supplicant with -e command line
1227 - this code is not included in the default build; Makefile need to
1228 be edited for this (uncomment lines for selected functionality)
1229 - EAP-TLS and EAP-PEAP require openssl libraries
1230 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1231 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1232 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1233 EAPOL-Key frames instead of WPA key handshakes)
1234 * added support for IEEE 802.11i/RSN (WPA2)
1235 - improved PTK Key Handshake
1236 - PMKSA caching, pre-authentication
1237 * fixed wpa_supplicant to ignore possible extra data after WPA
1238 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1239 TPTK' error from message 3 of 4-Way Handshake in case the AP
1240 includes extra data after the EAPOL-Key)
1241 * added interface for external programs (frontends) to control
1243 - CLI example (wpa_cli) with interactive mode and command line
1245 - replaced SIGUSR1 status/statistics with the new control interface
1246 * made some feature compile time configurable
1247 - .config file for make
1248 - driver interfaces (hostap, hermes, ..)
1249 - EAPOL/EAP functions
1252 * Initial version of wpa_supplicant
