1 ChangeLog for wpa_supplicant
4 * nl80211: fixed number of issues with roaming
5 * avoid unnecessary roaming if multiple APs with similar signal
6 strength are present in scan results
7 * add TLS client events and server probing to ease design of
8 automatic detection of EAP parameters
9 * add option for server certificate matching (SHA256 hash of the
10 certificate) instead of trusted CA certificate configuration
11 * bsd: Cleaned up driver wrapper and added various low-level
13 * wpa_gui-qt4: do not show too frequent WPS AP available events as
15 * TNC: fixed issues with fragmentation
16 * EAP-TNC: add Flags field into fragment acknowledgement (needed to
17 interoperate with other implementations; may potentially breaks
18 compatibility with older wpa_supplicant/hostapd versions)
19 * wpa_cli: added option for using a separate process to receive event
20 messages to reduce latency in showing these
21 (CFLAGS += -DCONFIG_WPA_CLI_FORK=y in .config to enable this)
22 * maximum BSS table size can now be configured (bss_max_count)
23 * BSSes to be included in the BSS table can be filtered based on
24 configured SSIDs to save memory (filter_ssids)
25 * fix number of issues with IEEE 802.11r/FT; this version is not
26 backwards compatible with old versions
27 * nl80211: add support for IEEE 802.11r/FT protocol (both over-the-air
29 * add freq_list network configuration parameter to allow the AP
30 selection to filter out entries based on the operating channel
31 * add signal strength change events for bgscan; this allows more
32 dynamic changes to background scanning interval based on changes in
33 the signal strength with the current AP; this improves roaming within
34 ESS quite a bit, e.g., with bgscan="simple:30:-45:300" in the network
35 configuration block to request background scans less frequently when
36 signal strength remains good and to automatically trigger background
37 scans whenever signal strength drops noticeably
38 (this is currently only available with nl80211)
39 * add BSSID and reason code (if available) to disconnect event messages
40 * wpa_gui-qt4: more complete support for translating the GUI with
41 linguist and add German translation
42 * fix DH padding with internal crypto code (mainly, for WPS)
43 * do not trigger initial scan automatically anymore if there are no
47 * cleaned up driver wrapper API (struct wpa_driver_ops); the new API
48 is not fully backwards compatible, so out-of-tree driver wrappers
49 will need modifications
50 * cleaned up various module interfaces
51 * merge hostapd and wpa_supplicant developers' documentation into a
53 * nl80211: use explicit deauthentication to clear cfg80211 state to
54 avoid issues when roaming between APs
55 * dbus: major design changes in the new D-Bus API
56 (fi.w1.wpa_supplicant1)
57 * nl80211: added support for IBSS networks
58 * added internal debugging mechanism with backtrace support and memory
59 allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y)
60 * added WPS ER unsubscription command to more cleanly unregister from
61 receiving UPnP events when ER is terminated
62 * cleaned up AP mode operations to avoid need for virtual driver_ops
64 * added BSS table to maintain more complete scan result information
65 over multiple scans (that may include only partial results)
66 * wpa_gui-qt4: update Peers dialog information more dynamically while
67 the dialog is kept open
68 * fixed PKCS#12 use with OpenSSL 1.0.0
69 * driver_wext: Added cfg80211-specific optimization to avoid some
70 unnecessary scans and to speed up association
73 * increased wpa_cli ping interval to 5 seconds and made this
74 configurable with a new command line options (-G<seconds>)
75 * fixed scan buffer processing with WEXT to handle up to 65535
76 byte result buffer (previously, limited to 32768 bytes)
77 * allow multiple driver wrappers to be specified on command line
78 (e.g., -Dnl80211,wext); the first one that is able to initialize the
79 interface will be used
80 * added support for multiple SSIDs per scan request to optimize
81 scan_ssid=1 operations in ap_scan=1 mode (i.e., search for hidden
82 SSIDs); this requires driver support and can currently be used only
84 * added support for WPS USBA out-of-band mechanism with USB Flash
85 Drives (UFD) (CONFIG_WPS_UFD=y)
86 * driver_ndis: add PAE group address to the multicast address list to
87 fix wired IEEE 802.1X authentication
88 * fixed IEEE 802.11r key derivation function to match with the standard
89 (note: this breaks interoperability with previous version) [Bug 303]
90 * added better support for drivers that allow separate authentication
91 and association commands (e.g., mac80211-based Linux drivers with
92 nl80211; SME in wpa_supplicant); this allows over-the-air FT protocol
93 to be used (IEEE 802.11r)
94 * fixed SHA-256 based key derivation function to match with the
95 standard when using CCMP (for IEEE 802.11r and IEEE 802.11w)
96 (note: this breaks interoperability with previous version) [Bug 307]
97 * use shared driver wrapper files with hostapd
98 * added AP mode functionality (CONFIG_AP=y) with mode=2 in the network
99 block; this can be used for open and WPA2-Personal networks
100 (optionally, with WPS); this links in parts of hostapd functionality
102 * wpa_gui-qt4: added new Peers dialog to show information about peers
103 (other devices, including APs and stations, etc. in the neighborhood)
104 * added support for WPS External Registrar functionality (configure APs
105 and enroll new devices); can be used with wpa_gui-qt4 Peers dialog
106 and wpa_cli commands wps_er_start, wps_er_stop, wps_er_pin,
107 wps_er_pbc, wps_er_learn
108 (this can also be used with a new 'none' driver wrapper if no
109 wireless device or IEEE 802.1X on wired is needed)
110 * driver_nl80211: multiple updates to provide support for new Linux
111 nl80211/mac80211 functionality
112 * updated management frame protection to use IEEE Std 802.11w-2009
113 * fixed number of small WPS issues and added workarounds to
114 interoperate with common deployed broken implementations
115 * added support for NFC out-of-band mechanism with WPS
116 * driver_ndis: fixed wired IEEE 802.1X authentication with PAE group
118 * added preliminary support for IEEE 802.11r RIC processing
119 * added support for specifying subset of enabled frequencies to scan
120 (scan_freq option in the network configuration block); this can speed
121 up scanning process considerably if it is known that only a small
122 subset of channels is actually used in the network (this is currently
123 supported only with -Dnl80211)
124 * added a workaround for race condition between receiving the
125 association event and the following EAPOL-Key
126 * added background scan and roaming infrastructure to allow
127 network-specific optimizations to be used to improve roaming within
129 * added new DBus interface (fi.w1.wpa_supplicant1)
132 * added support for Wi-Fi Protected Setup (WPS)
133 (wpa_supplicant can now be configured to act as a WPS Enrollee to
134 enroll credentials for a network using PIN and PBC methods; in
135 addition, wpa_supplicant can act as a wireless WPS Registrar to
136 configure an AP); WPS support can be enabled by adding CONFIG_WPS=y
137 into .config and setting the runtime configuration variables in
138 wpa_supplicant.conf (see WPS section in the example configuration
139 file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to
140 manage WPS negotiation; see README-WPS for more details
141 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
142 * added support for using driver_test over UDP socket
143 * fixed PEAPv0 Cryptobinding interoperability issue with Windows Server
144 2008 NPS; optional cryptobinding is now enabled (again) by default
145 * fixed PSK editing in wpa_gui
146 * changed EAP-GPSK to use the IANA assigned EAP method type 51
147 * added a Windows installer that includes WinPcap and all the needed
148 DLLs; in addition, it set up the registry automatically so that user
149 will only need start wpa_gui to get prompted to start the wpasvc
150 servide and add a new interface if needed through wpa_gui dialog
151 * updated management frame protection to use IEEE 802.11w/D7.0
154 * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
155 (can be used to simulate test SIM/USIM card with a known private key;
156 enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
157 and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
158 * added a new network configuration option, wpa_ptk_rekey, that can be
159 used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
160 against TKIP deficiencies
161 * added an optional mitigation mechanism for certain attacks against
162 TKIP by delaying Michael MIC error reports by a random amount of time
163 between 0 and 60 seconds; this can be enabled with a build option
164 CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
165 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
167 * updated OpenSSL code for EAP-FAST to use an updated version of the
168 session ticket overriding API that was included into the upstream
169 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
170 needed with that version anymore)
171 * updated userspace MLME instructions to match with the current Linux
172 mac80211 implementation; please also note that this can only be used
173 with driver_nl80211.c (the old code from driver_wext.c was removed)
174 * added support (Linux only) for RoboSwitch chipsets (often found in
175 consumer grade routers); driver interface 'roboswitch'
176 * fixed canceling of PMKSA caching when using drivers that generate
177 RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
181 * added support for SHA-256 as X.509 certificate digest when using the
182 internal X.509/TLSv1 implementation
183 * updated management frame protection to use IEEE 802.11w/D6.0
184 * added support for using SHA256-based stronger key derivation for WPA2
186 * fixed FT (IEEE 802.11r) authentication after a failed association to
188 * added support for configuring Phase 2 (inner/tunneled) authentication
189 method with wpa_gui-qt4
192 * added support for EAP Sequences in EAP-FAST Phase 2
193 * added support for using TNC with EAP-FAST
194 * added driver_ps3 for the PS3 Linux wireless driver
195 * added support for optional cryptobinding with PEAPv0
196 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
197 allow fallback to full handshake if server rejects PAC-Opaque
198 * added fragmentation support for EAP-TNC
199 * added support for parsing PKCS #8 formatted private keys into the
200 internal TLS implementation (both PKCS #1 RSA key and PKCS #8
201 encapsulated RSA key can now be used)
202 * added option of using faster, but larger, routines in the internal
203 LibTomMath (for internal TLS implementation) to speed up DH and RSA
204 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
205 * fixed race condition between disassociation event and group key
206 handshake to avoid getting stuck in incorrect state [Bug 261]
207 * fixed opportunistic key caching (proactive_key_caching)
210 * removed 'nai' and 'eappsk' network configuration variables that were
211 previously used for configuring user identity and key for EAP-PSK,
212 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
213 replacement for 'nai' (if old configuration used a separate
214 'identity' value, that would now be configured as
215 'anonymous_identity'). 'password' field is now used as the
216 replacement for 'eappsk' (it can also be set using hexstring to
217 present random binary data)
218 * removed '-w' command line parameter (wait for interface to be added,
219 if needed); cleaner way of handling this functionality is to use an
220 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
221 when an interface is added
222 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
223 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
224 indicating when new scan results become available
225 * added new ctrl_iface command, BSS, to allow scan results to be
226 fetched without hitting the message size limits (this command
227 can be used to iterate through the scan results one BSS at the time)
228 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
229 attributes in EAP-SIM Start/Response when using fast reauthentication
230 * fixed EAPOL not to end up in infinite loop when processing dynamic
231 WEP keys with IEEE 802.1X
232 * fixed problems in getting NDIS events from WMI on Windows 2000
235 * added support for Makefile builds to include debug-log-to-a-file
236 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
237 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
238 lengths properly to avoid potential crash caused by invalid messages
239 * added data structure for storing allocated buffers (struct wpabuf);
240 this does not affect wpa_supplicant usage, but many of the APIs
241 changed and various interfaces (e.g., EAP) is not compatible with old
243 * added support for protecting EAP-AKA/Identity messages with
244 AT_CHECKCODE (optional feature in RFC 4187)
245 * added support for protected result indication with AT_RESULT_IND for
246 EAP-SIM and EAP-AKA (phase1="result_ind=1")
247 * added driver_wext workaround for race condition between scanning and
248 association with drivers that take very long time to scan all
249 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
250 using a longer hardcoded timeout for the scan if the driver supports
251 notifications for scan completion (SIOCGIWSCAN event); this helps,
252 e.g., in cases where wpa_supplicant and madwifi driver ended up in
253 loop where the driver did not even try to associate
254 * stop EAPOL timer tick when no timers are in use in order to reduce
255 power consumption (no need to wake up the process once per second)
257 * added support for privilege separation (run only minimal part of
258 wpa_supplicant functionality as root and rest as unprivileged,
259 non-root process); see 'Privilege separation' in README for details;
260 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
262 * changed scan results data structure to include all information
263 elements to make it easier to support new IEs; old get_scan_result()
264 driver_ops is still supported for backwards compatibility (results
265 are converted internally to the new format), but all drivers should
266 start using the new get_scan_results2() to make them more likely to
267 work with new features
268 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
269 application, i.e., it does not require Qt3Support anymore; Windows
270 binary of wpa_gui.exe is now from this directory and only requires
271 QtCore4.dll and QtGui4.dll libraries
272 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
273 available as a separate package to make wpa_gui installation easier:
274 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
275 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
276 only shared key/password authentication is supported in this version
279 * added support for configuring password as NtPasswordHash
280 (16-byte MD4 hash of password) in hash:<32 hex digits> format
281 * added support for fallback from abbreviated TLS handshake to
282 full handshake when using EAP-FAST (e.g., due to an expired
284 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
285 draft (draft-ietf-emu-eap-gpsk-07.txt)
286 * added support for drivers that take care of RSN 4-way handshake
287 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
288 WPA_ALG_PMK in set_key)
289 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
290 .config); this version supports only ap_scan=2 mode and allow the
291 driver to take care of the 4-way handshake
292 * fixed a buffer overflow in parsing TSF from scan results when using
293 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
295 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
296 * fixed an integer overflow issue in the ASN.1 parser used by the
297 (experimental) internal TLS implementation to avoid a potential
299 * fixed a race condition with -W option (wait for a control interface
300 monitor before starting) that could have caused the first messages to
302 * added support for processing TNCC-TNCS-Messages to report
303 recommendation (allow/none/isolate) when using TNC [Bug 243]
306 * added network configuration parameter 'frequency' for setting
307 initial channel for IBSS (adhoc) networks
308 * added experimental IEEE 802.11r/D6.0 support
309 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
310 * updated EAP-PSK to use the IANA-allocated EAP type 47
311 * fixed EAP-PAX key derivation
312 * fixed EAP-PSK bit ordering of the Flags field
313 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
314 tunnelled identity request (previously, the identifier from the outer
315 method was used, not the tunnelled identifier which could be
317 * added support for fragmentation of outer TLS packets during Phase 2
318 of EAP-PEAP/TTLS/FAST
319 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
320 * added support for EAP-FAST authentication with inner methods that
321 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
322 for PAC provisioning)
323 * added support for authenticated EAP-FAST provisioning
324 * added support for configuring maximum number of EAP-FAST PACs to
325 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
326 * added support for storing EAP-FAST PACs in binary format
327 (fast_pac_format=binary in phase1 string)
328 * fixed dbus ctrl_iface to validate message interface before
329 dispatching to avoid a possible segfault [Bug 190]
330 * fixed PeerKey key derivation to use the correct PRF label
331 * updated Windows binary build to link against OpenSSL 0.9.8d and
332 added support for EAP-FAST
333 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
334 draft (draft-ietf-emu-eap-gpsk-04.txt)
335 * fixed EAP-AKA Notification processing to allow Notification to be
336 processed after AKA Challenge response has been sent
337 * updated to use IEEE 802.11w/D2.0 for management frame protection
339 * fixed EAP-TTLS implementation not to crash on use of freed memory
340 if TLS library initialization fails
341 * added support for EAP-TNC (Trusted Network Connect)
342 (this version implements the EAP-TNC method and EAP-TTLS changes
343 needed to run two methods in sequence (IF-T) and the IF-IMC and
344 IF-TNCCS interfaces from TNCC)
347 * added experimental, integrated TLSv1 client implementation with the
348 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
349 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
350 .config); this can be useful, e.g., if the target system does not
351 have a suitable TLS library and a minimal code size is required
352 (total size of this internal TLS/crypto code is bit under 50 kB on
353 x86 and the crypto code is shared by rest of the supplicant so some
354 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
355 * removed STAKey handshake since PeerKey handshake has replaced it in
356 IEEE 802.11ma and there are no known deployments of STAKey
357 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
358 draft (draft-ietf-emu-eap-gpsk-01.txt)
359 * added preliminary implementation of IEEE 802.11w/D1.0 (management
361 (Note: this requires driver support to work properly.)
362 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
363 * fixed Windows named pipes ctrl_iface to not stop listening for
364 commands if client program opens a named pipe and closes it
365 immediately without sending a command
366 * fixed USIM PIN status determination for the case that PIN is not
367 needed (this allows EAP-AKA to be used with USIM cards that do not
369 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
370 be used with cards that do not support file selection based on
372 * added support for matching the subjectAltName of the authentication
373 server certificate against multiple name components (e.g.,
374 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
375 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
376 affects IEEE 802.1X with dynamic WEP keys)
377 * changed ctrl_iface network configuration 'get' operations to not
378 return password/key material; if these fields are requested, "*"
379 will be returned if the password/key is set, but the value of the
380 parameter is not exposed
383 * added support for building Windows version with UNICODE defined
384 (wide-char functions)
385 * driver_ndis: fixed static WEP configuration to avoid race condition
386 issues with some NDIS drivers between association and setting WEP
388 * driver_ndis: added validation for IELength value in scan results to
389 avoid crashes when using buggy NDIS drivers [Bug 165]
390 * fixed Release|Win32 target in the Visual Studio project files
391 (previously, only Debug|Win32 target was set properly)
392 * changed control interface API call wpa_ctrl_pending() to allow it to
393 return -1 on error (e.g., connection lost); control interface clients
394 will need to make sure that they verify that the value is indeed >0
395 when determining whether there are pending messages
396 * added an alternative control interface backend for Windows targets:
397 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
398 control interface mechanism for Windows builds (previously, UDP to
400 * changed ctrl_interface configuration for UNIX domain sockets:
401 - deprecated ctrl_interface_group variable (it may be removed in
403 - allow both directory and group be configured with ctrl_interface
404 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
405 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
406 case when group is not changed
407 * added support for controlling more than one interface per process in
409 * added a workaround for a case where the AP is using unknown address
410 (e.g., MAC address of the wired interface) as the source address for
411 EAPOL-Key frames; previously, that source address was used as the
412 destination for EAPOL-Key frames and in key derivation; now, BSSID is
413 used even if the source address does not match with it
414 (this resolves an interoperability issue with Thomson SpeedTouch 580)
415 * added a workaround for UDP-based control interface (which was used in
416 Windows builds before this release) to prevent packets with forged
417 addresses from being accepted as local control requests
418 * removed ndis_events.cpp and possibility of using external
419 ndis_events.exe; C version (ndis_events.c) is fully functional and
420 there is no desire to maintain two separate versions of this
422 * ndis_events: Changed NDIS event notification design to use WMI to
423 learn the adapter description through Win32_PnPEntity class; this
424 should fix some cases where the adapter name was not recognized
425 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
427 * fixed selection of the first network in ap_scan=2 mode; previously,
428 wpa_supplicant could get stuck in SCANNING state when only the first
429 network for enabled (e.g., after 'wpa_cli select_network 0')
430 * winsvc: added support for configuring ctrl_interface parameters in
431 registry (ctrl_interface string value in
432 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
433 required to enable control interface (previously, this was hardcoded
435 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
436 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
439 * fixed build with CONFIG_STAKEY=y [Bug 143]
440 * added support for doing MLME (IEEE 802.11 management frame
441 processing) in wpa_supplicant when using Devicescape IEEE 802.11
442 stack (wireless-dev.git tree)
443 * added a new network block configuration option, fragment_size, to
444 configure the maximum EAP fragment size
445 * driver_ndis: Disable WZC automatically for the selected interface to
446 avoid conflicts with two programs trying to control the radio; WZC
447 will be re-enabled (if it was enabled originally) when wpa_supplicant
449 * added an experimental TLSv1 client implementation
450 (CONFIG_TLS=internal) that can be used instead of an external TLS
451 library, e.g., to reduce total size requirement on systems that do
452 not include any TLS library by default (this is not yet complete;
453 basic functionality is there, but certificate validation is not yet
455 * added PeerKey handshake implementation for IEEE 802.11e
456 direct link setup (DLS) to replace STAKey handshake
457 * fixed WPA PSK update through ctrl_iface for the case where the old
458 PSK was derived from an ASCII passphrase and the new PSK is set as
459 a raw PSK (hex string)
460 * added new configuration option for identifying which network block
461 was used (id_str in wpa_supplicant.conf; included on
462 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
463 variable in wpa_cli action scripts; in addition WPA_ID variable is
464 set to the current unique identifier that wpa_supplicant assigned
465 automatically for the network and that can be used with
466 GET_NETWORK/SET_NETWORK ctrl_iface commands)
467 * wpa_cli action script is now called only when the connect/disconnect
468 status changes or when associating with a different network
469 * fixed configuration parser not to remove CCMP from group cipher list
470 if WPA-None (adhoc) is used (pairwise=NONE in that case)
471 * fixed integrated NDIS events processing not to hang the process due
472 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
473 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
474 draft-clancy-emu-eap-shared-secret-00.txt)
475 * added Microsoft Visual Studio 2005 solution and project files for
476 build wpa_supplicant for Windows (see vs2005 subdirectory)
477 * eloop_win: fixed unregistration of Windows events
478 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
479 at the end of RSN pre-authentication and added unregistration of
480 a Windows event to avoid getting eloop_win stuck with an invalid
482 * driver_ndis: added support for selecting AP based on BSSID
483 * added new environmental variable for wpa_cli action scripts:
484 WPA_CTRL_DIR is the current control interface directory
485 * driver_ndis: added support for using NDISUIO instead of WinPcap for
486 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
487 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
488 wpa_supplicant without requiring WinPcap; note that using NDISUIO
489 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
490 only one application to open the device
491 * changed NDIS driver naming to only include device GUID, e.g.,
492 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
493 specific \Device\NPF_ prefix before the GUID; the prefix is still
494 allowed for backwards compatibility, but it is not required anymore
495 when specifying the interface
496 * driver_ndis: re-initialize driver interface is the adapter is removed
497 and re-inserted [Bug 159]
498 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
499 big endian hosts [Bug 146]
502 * fixed EAP-GTC response to include correct user identity when run as
503 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
504 * driver_ndis: Fixed encryption mode configuration for unencrypted
505 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
506 refused to associate with open networks) [Bug 106]
507 * driver_ndis: use BSSID OID polling to detect when IBSS network is
508 formed even when ndis_events code is included since some NDIS drivers
509 do not generate media connect events in IBSS mode
510 * config_winreg: allow global ctrl_interface parameter to be configured
512 * config_winreg: added support for saving configuration data into
514 * added support for controlling network device operational state
515 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
516 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
517 that can use this information)
518 * driver_wext: added support for WE-21 change to SSID configuration
519 * driver_wext: fixed privacy configuration for static WEP keys mode
521 * added an optional driver_ops callback for MLME-SETPROTECTION.request
523 * added support for EAP-SAKE (no EAP method number allocated yet, so
524 this is using the same experimental type 255 as EAP-PSK)
525 * added support for dynamically loading EAP methods (.so files) instead
526 of requiring them to be statically linked in; this is disabled by
527 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
531 * do not try to use USIM APDUs when initializing PC/SC for SIM card
532 access for a network that has not enabled EAP-AKA
533 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
534 v0.5.1 due to the new support for expanded EAP types)
535 * added support for generating EAP Expanded Nak
536 * try to fetch scan results once before requesting new scan when
537 starting up in ap_scan=1 mode (this can speed up initial association
538 a lot with, e.g., madwifi-ng driver)
539 * added support for receiving EAPOL frames from a Linux bridge
540 interface (-bbr0 on command line)
541 * fixed EAPOL re-authentication for sessions that used PMKSA caching
542 * changed EAP method registration to use a dynamic list of methods
543 instead of a static list generated at build time
544 * fixed PMKSA cache deinitialization not to use freed memory when
545 removing PMKSA entries
546 * fixed a memory leak in EAP-TTLS re-authentication
547 * reject WPA/WPA2 message 3/4 if it does not include any valid
549 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
550 if the driver does not support SIOCSIWAUTH
553 * driver_test: added better support for multiple APs and STAs by using
554 a directory with sockets that include MAC address for each device in
555 the name (driver_param=test_dir=/tmp/test)
556 * added support for EAP expanded type (vendor specific EAP methods)
557 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
558 option can be changed if needed
559 * wpa_cli/wpa_gui: skip non-socket files in control directory when
560 using UNIX domain sockets; this avoids selecting an incorrect
561 interface (e.g., a PID file could be in this directory, even though
562 use of this directory for something else than socket files is not
564 * fixed TLS library deinitialization after RSN pre-authentication not
565 to disable TLS library for normal authentication
566 * driver_wext: Remove null-termination from SSID length if the driver
567 used it; some Linux drivers do this and they were causing problems in
568 wpa_supplicant not finding matching configuration block. This change
569 would break a case where the SSID actually ends in '\0', but that is
570 not likely to happen in real use.
571 * fixed PMKSA cache processing not to trigger deauthentication if the
572 current PMKSA cache entry is replaced with a valid new entry
573 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
574 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
577 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
578 * added experimental STAKey handshake implementation for IEEE 802.11e
579 direct link setup (DLS); note: this is disabled by default in both
580 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
582 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
583 decrypt AT_ENCR_DATA attributes correctly
584 * fixed EAP-AKA to allow resynchronization within the same session
585 * made code closer to ANSI C89 standard to make it easier to port to
586 other C libraries and compilers
587 * started moving operating system or C library specific functions into
588 wrapper functions defined in os.h and implemented in os_*.c to make
590 * wpa_supplicant can now be built with Microsoft Visual C++
591 (e.g., with the freely available Toolkit 2003 version or Visual
592 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
593 example makefile for nmake
594 * added support for using Windows registry for command line parameters
595 (CONFIG_MAIN=main_winsvc) and configuration data
596 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
597 contents; this version can be run both as a Windows service and as a
598 normal application; 'wpasvc.exe app' to start as applicant,
599 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
600 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
602 * made it possible to link ndis_events.exe functionality into
603 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
604 * added better support for multiple control interface backends
605 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
606 * fixed PC/SC code to use correct length for GSM AUTH command buffer
607 and to not use pioRecvPci with SCardTransmit() calls; these were not
608 causing visible problems with pcsc-lite, but Windows Winscard.dll
609 refused the previously used parameters; this fixes EAP-SIM and
610 EAP-AKA authentication using SIM/USIM card under Windows
611 * added new event loop implementation for Windows using
612 WaitForMultipleObject() instead of select() in order to allow waiting
613 for non-socket objects; this can be selected with
614 CONFIG_ELOOP=eloop_win in .config
615 * added support for selecting l2_packet implementation in .config
616 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
617 winpcap, freebsd, none)
618 * added new l2_packet implementation for WinPcap
619 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
620 reduce latency in EAPOL receive processing from about 100 ms to about
622 * added support for EAP-FAST key derivation using other ciphers than
623 RC4-128-SHA for authentication and AES128-SHA for provisioning
624 * added support for configuring CA certificate as DER file and as a
626 * fixed private key configuration as configuration blob and added
627 support for using PKCS#12 as a blob
628 * tls_gnutls: added support for using PKCS#12 files; added support for
630 * added support for loading trusted CA certificates from Windows
631 certificate store: ca_cert="cert_store://<name>", where <name> is
632 likely CA (Intermediate CA certificates) or ROOT (root certificates)
633 * added C version of ndis_events.cpp and made it possible to build this
634 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
635 easily on cross-compilation builds
636 * added wpasvc.exe into Windows binary release; this is an alternative
637 version of wpa_supplicant.exe with configuration backend using
638 Windows registry and with the entry point designed to run as a
640 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
641 wpasvc.exe and removed this additional tool from the Windows binary
642 release since it is not needed anymore
643 * load winscard.dll functions dynamically when building with MinGW
644 since MinGW does not yet include winscard library
646 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
647 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
648 and WinPcap to receive frames sent to PAE group address
649 * disable EAP state machine when IEEE 802.1X authentication is not used
650 in order to get rid of bogus "EAP failed" messages
651 * fixed OpenSSL error reporting to go through all pending errors to
652 avoid confusing reports of old errors being reported at later point
654 * fixed configuration file updating to not write empty variables
655 (e.g., proto or key_mgmt) that the file parser would not accept
656 * fixed ADD_NETWORK ctrl_iface command to use the same default values
657 for variables as empty network definitions read from config file
659 * fixed EAP state machine to not discard EAP-Failure messages in many
660 cases (e.g., during TLS handshake)
661 * fixed a infinite loop in private key reading if the configured file
662 cannot be parsed successfully
663 * driver_madwifi: added support for madwifi-ng
664 * wpa_gui: do not display password/PSK field contents
665 * wpa_gui: added CA certificate configuration
666 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
667 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
668 the new AP is using different WPA/RSN IE
669 * use longer timeout for IEEE 802.11 association to avoid problems with
670 drivers that may take more than five second to associate
673 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
674 RSN IE, but WPA IE would match with wpa_supplicant configuration
675 * added support for named configuration blobs in order to avoid having
676 to use file system for external files (e.g., certificates);
677 variables can be set to "blob://<blob name>" instead of file path to
678 use a named blob; supported fields: pac_file, client_cert,
680 * fixed RSN pre-authentication (it was broken in the clean up of WPA
681 state machine interface in v0.4.5)
682 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
683 sure the driver configures broadcast decryption correctly
684 * added ca_path (and ca_path2) configuration variables that can be used
685 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
686 system-wide trusted CA list
687 * added support for starting wpa_supplicant without a configuration
688 file (-C argument must be used to set ctrl_interface parameter for
689 this case; in addition, -p argument can be used to provide
690 driver_param; these new arguments can also be used with a
691 configuration to override the values from the configuration)
692 * added global control interface that can be optionally used for adding
693 and removing network interfaces dynamically (-g command line argument
694 for both wpa_supplicant and wpa_cli) without having to restart
695 wpa_supplicant process
697 - try to save configuration whenever something is modified
698 - added WEP key configuration
699 - added possibility to edit the current network configuration
700 * driver_ndis: fixed driver polling not to increase frequency on each
701 received EAPOL frame due to incorrectly cancelled timeout
702 * added simple configuration file examples (in examples subdirectory)
703 * fixed driver_wext.c to filter wireless events based on ifindex to
704 avoid interfaces receiving events from other interfaces
705 * delay sending initial EAPOL-Start couple of seconds to speed up
706 authentication for the most common case of Authenticator starting
707 EAP authentication immediately after association
710 * added a workaround for clearing keys with ndiswrapper to allow
711 roaming from WPA enabled AP to plaintext one
712 * added docbook documentation (doc/docbook) that can be used to
713 generate, e.g., man pages
714 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
715 PF_PACKET in order to prepare for network devices that do not use
716 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
717 * use receipt of EAPOL-Key frame as a lower layer success indication
718 for EAP state machine to allow recovery from dropped EAP-Success
720 * cleaned up internal EAPOL frame processing by not including link
721 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
722 header is added only when transmitted the frame; this makes it easier
723 to use wpa_supplicant on link layers that use different header than
725 * updated EAP-PSK to use draft 9 by default since this can now be
726 tested with hostapd; removed support for draft 3, including
727 server_nai configuration option from network blocks
728 * driver_wired: add PAE address to the multicast address list in order
729 to be able to receive EAPOL frames with drivers that do not include
730 these multicast addresses by default
731 * driver_wext: add support for WE-19
732 * added support for multiple configuration backends (CONFIG_BACKEND
733 option); currently, only 'file' is supported (i.e., the format used
734 in wpa_supplicant.conf)
735 * added support for updating configuration ('wpa_cli save_config');
736 this is disabled by default and can be enabled with global
737 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
738 and wpa_gui to store the configuration changes in a permanent store
739 * added GET_NETWORK ctrl_iface command
740 (e.g., 'wpa_cli get_network 0 ssid')
743 * replaced OpenSSL patch for EAP-FAST support
744 (openssl-tls-extensions.patch) with a more generic and correct
745 patch (the new patch is not compatible with the previous one, so the
746 OpenSSL library will need to be patched with the new patch in order
747 to be able to build wpa_supplicant with EAP-FAST support)
748 * added support for using Windows certificate store (through CryptoAPI)
749 for client certificate and private key operations (EAP-TLS)
750 (see wpa_supplicant.conf for more information on how to configure
751 this with private_key)
752 * ported wpa_gui to Windows
753 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
754 built with the open source version of the Qt4 for Windows
755 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
756 with drivers that do not support WPA
757 * ndis_events: fixed Windows 2000 support
758 * added support for enabling/disabling networks from the list of all
759 configured networks ('wpa_cli enable_network <network id>' and
760 'wpa_cli disable_network <network id>')
761 * added support for adding and removing network from the current
762 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
763 <network id>'); added networks are disabled by default and they can
764 be enabled with enable_network command once the configuration is done
765 for the new network; note: configuration file is not yet updated, so
766 these new networks are lost when wpa_supplicant is restarted
767 * added support for setting network configuration parameters through
768 the control interface, for example:
769 wpa_cli set_network 0 ssid "\"my network\""
770 * fixed parsing of strings that include both " and # within double
771 quoted area (e.g., "start"#end")
772 * added EAP workaround for PEAP session resumption: allow outer,
773 i.e., not tunneled, EAP-Success to terminate session since; this can
774 be disabled with eap_workaround=0
775 (this was allowed for PEAPv1 before, but now it is also allowed for
776 PEAPv0 since at least one RADIUS authentication server seems to be
777 doing this for PEAPv0, too)
778 * wpa_gui: added preliminary support for adding new networks to the
779 wpa_supplicant configuration (double click on the scan results to
780 open network configuration)
783 * removed interface for external EAPOL/EAP supplicant (e.g.,
784 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
785 anymore and is unlikely to be used by anyone
786 * driver_ndis: fixed WinPcap 3.0 support
787 * fixed build with CONFIG_DNET_PCAP=y on Linux
788 * l2_packet: moved different implementations into separate files
792 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
793 (note: ipw2100-1.1.0 is likely to require an update to work with
795 * added support for using ap_scan=2 mode with multiple network blocks;
796 wpa_supplicant will go through the networks one by one until the
797 driver reports a successful association; this uses the same order for
798 networks as scan_ssid=1 scans, i.e., the priority field is ignored
799 and the network block order in the file is used instead
800 * fixed a potential issue in RSN pre-authentication ending up using
801 freed memory if pre-authentication times out
802 * added support for matching alternative subject name extensions of the
803 authentication server certificate; new configuration variables
804 altsubject_match and altsubject_match2
805 * driver_ndis: added support for IEEE 802.1X authentication with wired
807 * added support for querying private key password (EAP-TLS) through the
808 control interface (wpa_cli/wpa_gui) if one is not included in the
810 * driver_broadcom: fixed couple of memory leaks in scan result
812 * EAP-PAX is now registered as EAP type 46
813 * fixed EAP-PAX MAC calculation
814 * fixed EAP-PAX CK and ICK key derivation
815 * added support for using password with EAP-PAX (as an alternative to
816 entering key with eappsk); SHA-1 hash of the password will be used as
818 * added support for arbitrary driver interface parameters through the
819 configuration file with a new driver_param field; this adds a new
820 driver_ops function set_param()
821 * added possibility to override l2_packet module with driver interface
822 API (new send_eapol handler); this can be used to implement driver
823 specific TX/RX functions for EAPOL frames
824 * fixed ctrl_interface_group processing for the case where gid is
825 entered as a number, not group name
826 * driver_test: added support for testing hostapd with wpa_supplicant
827 by using test driver interface without any kernel drivers or network
831 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
832 packets to be encrypted; this was apparently broken by the changed
833 ioctl order in v0.4.0
834 * driver_madwifi: added preliminary support for compiling against 'BSD'
835 branch of madwifi CVS tree
836 * added support for EAP-MSCHAPv2 password retries within the same EAP
837 authentication session
838 * added support for password changes with EAP-MSCHAPv2 (used when the
839 password has expired)
840 * added support for reading additional certificates from PKCS#12 files
841 and adding them to the certificate chain
842 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
844 * fixed a possible double free in EAP-TTLS fast-reauthentication when
845 identity or password is entered through control interface
846 * display EAP Notification messages to user through control interface
847 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
848 * added GUI version of wpa_cli, wpa_gui; this is not build
849 automatically with 'make'; use 'make wpa_gui' to build (this requires
850 Qt development tools)
851 * added 'disconnect' command to control interface for setting
852 wpa_supplicant in state where it will not associate before
853 'reassociate' command has been used
854 * added support for selecting a network from the list of all configured
855 networks ('wpa_cli select_network <network id>'; this disabled all
856 other networks; to re-enable, 'wpa_cli select_network any')
857 * added support for getting scan results through control interface
858 * added EAP workaround for PEAPv1 session resumption: allow outer,
859 i.e., not tunneled, EAP-Success to terminate session since; this can
860 be disabled with eap_workaround=0
862 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
863 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
864 used to reduce the size of the wpa_supplicant considerably if
865 debugging code is not needed
866 * fixed EAPOL-Key validation to drop packets with invalid Key Data
867 Length; such frames could have crashed wpa_supplicant due to buffer
869 * added support for wired authentication (IEEE 802.1X on wired
870 Ethernet); driver interface 'wired'
871 * obsoleted set_wpa() handler in the driver interface API (it can be
872 replaced by moving enable/disable functionality into init()/deinit())
873 (calls to set_wpa() are still present for backwards compatibility,
874 but they may be removed in the future)
875 * driver_madwifi: fixed association in plaintext mode
876 * modified the EAP workaround that accepts EAP-Success with incorrect
877 Identifier to be even less strict about verification in order to
878 interoperate with some authentication servers
879 * added support for sending TLS alerts
880 * added support for 'any' SSID wildcard; if ssid is not configured or
881 is set to an empty string, any SSID will be accepted for non-WPA AP
882 * added support for asking PIN (for SIM) from frontends (e.g.,
883 wpa_cli); if a PIN is needed, but not included in the configuration
884 file, a control interface request is sent and EAP processing is
885 delayed until the PIN is available
886 * added support for using external devices (e.g., a smartcard) for
887 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
888 new wpa_supplicant.conf variables:
889 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
890 - network: engine, engine_id, key_id
891 * added experimental support for EAP-PAX
892 * added monitor mode for wpa_cli (-a<path to a program to run>) that
893 allows external commands (e.g., shell scripts) to be run based on
894 wpa_supplicant events, e.g., when authentication has been completed
895 and data connection is ready; other related wpa_cli arguments:
896 -B (run in background), -P (write PID file); wpa_supplicant has a new
897 command line argument (-W) that can be used to make it wait until a
898 control interface command is received in order to avoid missing
900 * added support for opportunistic WPA2 PMKSA key caching (disabled by
901 default, can be enabled with proactive_key_caching=1)
902 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
903 Authenticator rejects PMKSA caching attempt and the driver is not
904 using assoc_info events
905 * added -P<pid file> argument for wpa_supplicant to write the current
906 process id into a file
908 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
909 * added new phase1 option parameter, include_tls_length=1, to force
910 wpa_supplicant to add TLS Message Length field to all TLS messages
911 even if the packet is not fragmented; this may be needed with some
912 authentication servers
913 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
914 using drivers that take care of AP selection (e.g., when using
916 * fixed reprocessing of pending request after ctrl_iface requests for
917 identity/password/otp
918 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
919 EAP-PEAP and EAP-TTLS
920 * all drivers using driver_wext: set interface up and select Managed
921 mode when starting wpa_supplicant; set interface down when exiting
922 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
923 ipw2100 and ipw2200; please note that this also changed the
924 configuration variable in .config to CONFIG_DRIVER_IPW
927 * fixed a busy loop introduced in v0.3.5 for scan result processing
928 when no matching AP is found
931 * added a workaround for an interoperability issue with a Cisco AP
933 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
934 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
935 retransmission of dropped frames)
936 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
937 (e.g., segfault when processing EAPOL-Key frames)
938 * fixed EAP workaround and fast reauthentication configuration for
939 RSN pre-authentication; previously these were disabled and
940 pre-authentication would fail if the used authentication server
941 requires EAP workarounds
942 * added support for blacklisting APs that fail or timeout
943 authentication in ap_scan=1 mode so that all APs are tried in cases
944 where the ones with strongest signal level are failing authentication
945 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
946 authentication attempt
947 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
948 in the previous authentication (previously, only Phase 1 success was
952 * added preliminary support for IBSS (ad-hoc) mode configuration
953 (mode=1 in network block); this included a new key_mgmt mode
954 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
955 key management; see wpa_supplicant.conf for more details and an
956 example on how to configure this (note: this is currently implemented
957 only for driver_hostapd.c, but the changes should be trivial to add
958 in associate() handler for other drivers, too (assuming the driver
960 * added preliminary port for native Windows (i.e., no cygwin) using
964 * added optional support for GNU Readline and History Libraries for
965 wpa_cli (CONFIG_READLINE)
966 * cleaned up EAP state machine <-> method interface and number of
967 small problems with error case processing not terminating on
968 EAP-Failure but waiting for timeout
969 * added couple of workarounds for interoperability issues with a
970 Cisco AP when using WPA2
971 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
972 Note: This requires a patch for openssl to add support for TLS
973 extensions and number of workarounds for operations without
974 certificates. Proof of concept type of experimental patch is
975 included in openssl-tls-extensions.patch.
978 * fixed private key loading for cases where passphrase is not set
979 * fixed Windows/cygwin L2 packet handler freeing; previous version
980 could cause a segfault when RSN pre-authentication was completed
981 * added support for PMKSA caching with drivers that generate RSN IEs
982 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
983 but similar code can be easily added to driver_ndiswrapper.c once
984 ndiswrapper gets full support for RSN PMKSA caching
985 * improved recovery from PMKID mismatches by requesting full EAP
986 authentication in case of failed PMKSA caching attempt
987 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
988 (this requires that ndis_events is ran while wpa_supplicant is
990 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
991 * added support for driver interfaces to replace the interface name
992 based on driver/OS specific mapping, e.g., in case of driver_ndis,
993 this allows the beginning of the adapter description to be used as
995 * added support for CR+LF (Windows-style) line ends in configuration
997 * driver_ndis: enable radio before starting scanning, disable radio
999 * modified association event handler to set portEnabled = FALSE before
1000 clearing port Valid in order to reset EAP state machine and avoid
1001 problems with new authentication getting ignored because of state
1002 machines ending up in AUTHENTICATED/SUCCESS state based on old
1004 * added support for driver events to add PMKID candidates in order to
1005 allow drivers to give priority to most likely roaming candidates
1006 * driver_hostap: moved PrivacyInvoked configuration to associate()
1007 function so that this will not be set for plaintext connections
1008 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
1009 interface can distinguish plaintext and IEEE 802.1X (no WPA)
1011 * fixed static WEP key configuration to use broadcast/default type for
1012 all keys (previously, the default TX key was configured as pairwise/
1014 * driver_ndis: added legacy WPA capability detection for non-WPA2
1016 * added support for setting static WEP keys for IEEE 802.1X without
1017 dynamic WEP keying (eapol_flags=0)
1020 * added support for reading PKCS#12 (PFX) files (as a replacement for
1021 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
1022 * fixed compilation with CONFIG_PCSC=y
1023 * added new ap_scan mode, ap_scan=2, for drivers that take care of
1024 association, but need to be configured with security policy and SSID,
1025 e.g., ndiswrapper and NDIS driver; this mode should allow such
1026 drivers to work with hidden SSIDs and optimized roaming; when
1027 ap_scan=2 is used, only the first network block in the configuration
1028 file is used and this configuration should have explicit security
1029 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
1030 group, proto variables
1031 * added experimental port of wpa_supplicant for Windows
1032 - driver_ndis.c driver interface (NDIS OIDs)
1033 - currently, this requires cygwin and WinPcap
1034 - small utility, win_if_list, can be used to get interface name
1035 * control interface can now be removed at build time; add
1036 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
1037 * optional Xsupplicant interface can now be removed at build time;
1038 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
1039 * added auth_alg to driver interface associate() parameters to make it
1040 easier for drivers to configure authentication algorithm as part of
1043 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
1044 * driver_broadcom: added new driver interface for Broadcom wl.o driver
1045 (a generic driver for Broadcom IEEE 802.11a/g cards)
1046 * wpa_cli: fixed parsing of -p <path> command line argument
1047 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
1048 ACK, not tunneled EAP-Success (of which only the first byte was
1049 actually send due to a bug in previous code); this seems to
1050 interoperate with most RADIUS servers that implements PEAPv1
1051 * PEAPv1: added support for terminating PEAP authentication on tunneled
1052 EAP-Success message; this can be configured by adding
1053 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
1054 (some RADIUS servers require this whereas others require a tunneled
1056 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
1057 the old label for key derivation; previously, the default was 1,
1058 but it looks like most existing PEAPv1 implementations use the old
1059 label which is thus more suitable default option
1060 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
1061 * fixed parsing of wep_tx_keyidx
1062 * added support for configuring list of allowed Phase 2 EAP types
1063 (for both EAP-PEAP and EAP-TTLS) instead of only one type
1064 * added support for configuring IEEE 802.11 authentication algorithm
1065 (auth_alg; mainly for using Shared Key authentication with static
1067 * added support for EAP-AKA (with UMTS SIM)
1068 * fixed couple of errors in PCSC handling that could have caused
1069 random-looking errors for EAP-SIM
1070 * added support for EAP-SIM pseudonyms and fast re-authentication
1071 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
1073 * added support for EAP-SIM with two challanges
1074 (phase1="sim_min_num_chal=3" can be used to require three challenges)
1075 * added support for configuring DH/DSA parameters for an ephemeral DH
1076 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
1077 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
1078 and optional DH key exchange to achieve forward secracy with RSA keys
1079 * added support for matching subject of the authentication server
1080 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
1081 configuration variables subject_match and subject_match2
1082 * changed SSID configuration in driver_wext.c (used by many driver
1083 interfaces) to use ssid_len+1 as the length for SSID since some Linux
1085 * fixed couple of unaligned reads in scan result parsing to fix WPA
1086 connection on some platforms (e.g., ARM)
1087 * added driver interface for Intel ipw2100 driver
1088 * added support for LEAP with WPA
1089 * added support for larger scan results report (old limit was 4 kB of
1090 data, i.e., about 35 or so APs) when using Linux wireless extensions
1092 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
1093 only if there is a PMKSA cache entry for the current AP
1094 * fixed error handling for case where reading of scan results fails:
1095 must schedule a new scan or wpa_supplicant will remain waiting
1097 * changed debug output to remove shared password/key material by
1098 default; all key information can be included with -K command line
1099 argument to match the previous behavior
1100 * added support for timestamping debug log messages (disabled by
1101 default, can be enabled with -t command line argument)
1102 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
1103 if keys are not configured to be used; this fixes IEEE 802.1X mode
1104 with drivers that use this information to configure whether Privacy
1105 bit can be in Beacon frames (e.g., ndiswrapper)
1106 * avoid clearing driver keys if no keys have been configured since last
1107 key clear request; this seems to improve reliability of group key
1108 handshake for ndiswrapper & NDIS driver which seems to be suffering
1109 of some kind of timing issue when the keys are cleared again after
1111 * changed driver interface API:
1112 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
1113 version is being used (now, this is set to 2; previously, it was
1115 - pass pointer to private data structure to all calls
1116 - the new API is not backwards compatible; all in-tree driver
1117 interfaces has been converted to the new API
1118 * added support for controlling multiple interfaces (radios) per
1119 wpa_supplicant process; each interface needs to be listed on the
1120 command line (-c, -i, -D arguments) with -N as a separator
1121 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
1122 * added a workaround for EAP servers that incorrectly use same Id for
1123 sequential EAP packets
1124 * changed libpcap/libdnet configuration to use .config variable,
1125 CONFIG_DNET_PCAP, instead of requiring Makefile modification
1126 * improved downgrade attack detection in IE verification of msg 3/4:
1127 verify both WPA and RSN IEs, if present, not only the selected one;
1128 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
1129 Probe Response frame, and RSN is enabled in wpa_supplicant
1131 * fixed WPA msg 3/4 processing to allow Key Data field contain other
1132 IEs than just one WPA IE
1133 * added support for FreeBSD and driver interface for the BSD net80211
1134 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
1135 required kernel mods have not yet been committed
1136 * made EAP workarounds configurable; enabled by default, can be
1137 disabled with network block option eap_workaround=0
1139 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
1140 * resolved couple of interoperability issues with EAP-PEAPv1 and
1141 Phase 2 (inner EAP) fragment reassembly
1142 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
1143 AP is using non-zero key index for the unicast key and key index zero
1144 for the broadcast key
1145 * driver_hostap: fixed IEEE 802.1X WEP key updates and
1146 re-authentication by allowing unencrypted EAPOL frames when not using
1148 * added a new driver interface, 'wext', which uses only standard,
1149 driver independent functionality in Linux wireless extensions;
1150 currently, this can be used only for non-WPA IEEE 802.1X mode, but
1151 eventually, this is to be extended to support full WPA/WPA2 once
1152 Linux wireless extensions get support for this
1153 * added support for mode in which the driver is responsible for AP
1154 scanning and selection; this is disabled by default and can be
1155 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
1156 this mode can be used, e.g., with generic 'wext' driver interface to
1157 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
1158 supporting wireless extensions.
1159 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
1160 operation with an AP that does not include SSID in the Beacon frames)
1161 * added support for new EAP authentication methods:
1162 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
1163 * added support for asking one-time-passwords from frontends (e.g.,
1164 wpa_cli); this 'otp' command works otherwise like 'password' command,
1165 but the password is used only once and the frontend will be asked for
1166 a new password whenever a request from authenticator requires a
1167 password; this can be used with both EAP-OTP and EAP-GTC
1168 * changed wpa_cli to automatically re-establish connection so that it
1169 does not need to be re-started when wpa_supplicant is terminated and
1171 * improved user data (identity/password/otp) requests through
1172 frontends: process pending EAPOL packets after getting new
1173 information so that full authentication does not need to be
1174 restarted; in addition, send pending requests again whenever a new
1175 frontend is attached
1176 * changed control frontends to use a new directory for socket files to
1177 make it easier for wpa_cli to automatically select between interfaces
1178 and to provide access control for the control interface;
1179 wpa_supplicant.conf: ctrl_interface is now a path
1180 (/var/run/wpa_supplicant is the recommended path) and
1181 ctrl_interface_group can be used to select which group gets access to
1182 the control interface;
1183 wpa_cli: by default, try to connect to the first interface available
1184 in /var/run/wpa_supplicant; this path can be overriden with -p option
1185 and an interface can be selected with -i option (i.e., in most common
1186 cases, wpa_cli does not need to get any arguments)
1187 * added support for LEAP
1188 * added driver interface for Linux ndiswrapper
1189 * added priority option for network blocks in the configuration file;
1190 this allows networks to be grouped based on priority (the scan
1191 results are searched for matches with network blocks in this order)
1194 * sort scan results to improve AP selection
1195 * fixed control interface socket removal for some error cases
1196 * improved scan requesting and authentication timeout
1197 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1199 * PEAP version can now be forced with phase1="peapver=<ver>"
1200 (mostly for testing; by default, the highest version supported by
1201 both the Supplicant and Authentication Server is selected
1203 * added support for madwifi driver (Atheros ar521x)
1204 * added a workaround for cases where AP sets Install Tx/Rx bit for
1205 WPA Group Key messages when pairwise keys are used (without this,
1206 the Group Key would be used for Tx and the AP would drop frames
1208 * added GSM SIM/USIM interface for GSM authentication algorithm for
1209 EAP-SIM; this requires pcsc-lite
1210 * added support for ATMEL AT76C5XXx driver
1211 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1212 does not include key data in the EAPOL-Key frame (i.e., part of
1213 EAP keying material is used as data encryption key)
1214 * added support for using plaintext and static WEP networks
1218 * added support for new EAP authentication methods:
1219 EAP-TTLS/EAP-MD5-Challenge
1221 EAP-TTLS/EAP-MSCHAPv2
1229 EAP-PEAP/MD5-Challenge
1231 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1232 * added support for anonymous identity (to be used when identity is
1233 sent in plaintext; real identity will be used within TLS protected
1234 tunnel (e.g., with EAP-TTLS)
1235 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1236 * added support for requesting identity and password information using
1237 control interface; in other words, the password for EAP-PEAP or
1238 EAP-TTLS does not need to be included in the configuration file since
1239 a frontand (e.g., wpa_cli) can ask it from the user
1240 * improved RSN pre-authentication to use a candidate list and process
1241 all candidates from each scan; not only one per scan
1242 * fixed RSN IE and WPA IE capabilities field parsing
1243 * ignore Tx bit in GTK IE when Pairwise keys are used
1244 * avoid making new scan requests during IEEE 802.1X negotiation
1245 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1246 with TLS support (this replaces the included implementation with
1247 library code to save about 8 kB since the library code is needed
1249 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1250 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1253 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1255 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1256 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1257 - EAP-MD5 (cannot be used with WPA-RADIUS)
1258 [draft-ietf-eap-rfc2284bis-09.txt]
1259 - EAP-TLS [RFC 2716]
1260 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1261 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1262 [draft-kamath-pppext-eap-mschapv2-00.txt]
1263 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1264 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1265 - new configuration file options: eap, identity, password, ca_cert,
1266 client_cert, privatekey, private_key_passwd
1267 - Xsupplicant is not required anymore, but it can be used by
1268 disabling the internal IEEE 802.1X Supplicant with -e command line
1270 - this code is not included in the default build; Makefile need to
1271 be edited for this (uncomment lines for selected functionality)
1272 - EAP-TLS and EAP-PEAP require openssl libraries
1273 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1274 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1275 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1276 EAPOL-Key frames instead of WPA key handshakes)
1277 * added support for IEEE 802.11i/RSN (WPA2)
1278 - improved PTK Key Handshake
1279 - PMKSA caching, pre-authentication
1280 * fixed wpa_supplicant to ignore possible extra data after WPA
1281 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1282 TPTK' error from message 3 of 4-Way Handshake in case the AP
1283 includes extra data after the EAPOL-Key)
1284 * added interface for external programs (frontends) to control
1286 - CLI example (wpa_cli) with interactive mode and command line
1288 - replaced SIGUSR1 status/statistics with the new control interface
1289 * made some feature compile time configurable
1290 - .config file for make
1291 - driver interfaces (hostap, hermes, ..)
1292 - EAPOL/EAP functions
1295 * Initial version of wpa_supplicant
