1 ChangeLog for wpa_supplicant
4 * added support for Wi-Fi Protected Setup (WPS)
5 (wpa_supplicant can now be configured to act as a WPS Enrollee to
6 enroll credentials for a network using PIN and PBC methods; in
7 addition, wpa_supplicant can act as a wireless WPS Registrar to
8 configure an AP); WPS support can be enabled by adding CONFIG_WPS=y
9 into .config and setting the runtime configuration variables in
10 wpa_supplicant.conf (see WPS section in the example configuration
11 file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to
12 manage WPS negotiation; see README-WPS for more details
13 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
14 * added support for using driver_test over UDP socket
17 * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
18 (can be used to simulate test SIM/USIM card with a known private key;
19 enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
20 and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
21 * added a new network configuration option, wpa_ptk_rekey, that can be
22 used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
23 against TKIP deficiencies
24 * added an optional mitigation mechanism for certain attacks against
25 TKIP by delaying Michael MIC error reports by a random amount of time
26 between 0 and 60 seconds; this can be enabled with a build option
27 CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
28 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
30 * updated OpenSSL code for EAP-FAST to use an updated version of the
31 session ticket overriding API that was included into the upstream
32 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
33 needed with that version anymore)
34 * updated userspace MLME instructions to match with the current Linux
35 mac80211 implementation; please also note that this can only be used
36 with driver_nl80211.c (the old code from driver_wext.c was removed)
37 * added support (Linux only) for RoboSwitch chipsets (often found in
38 consumer grade routers); driver interface 'roboswitch'
39 * fixed canceling of PMKSA caching when using drivers that generate
40 RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
44 * added support for SHA-256 as X.509 certificate digest when using the
45 internal X.509/TLSv1 implementation
46 * updated management frame protection to use IEEE 802.11w/D6.0
47 * added support for using SHA256-based stronger key derivation for WPA2
49 * fixed FT (IEEE 802.11r) authentication after a failed association to
51 * added support for configuring Phase 2 (inner/tunneled) authentication
52 method with wpa_gui-qt4
55 * added support for EAP Sequences in EAP-FAST Phase 2
56 * added support for using TNC with EAP-FAST
57 * added driver_ps3 for the PS3 Linux wireless driver
58 * added support for optional cryptobinding with PEAPv0
59 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
60 allow fallback to full handshake if server rejects PAC-Opaque
61 * added fragmentation support for EAP-TNC
62 * added support for parsing PKCS #8 formatted private keys into the
63 internal TLS implementation (both PKCS #1 RSA key and PKCS #8
64 encapsulated RSA key can now be used)
65 * added option of using faster, but larger, routines in the internal
66 LibTomMath (for internal TLS implementation) to speed up DH and RSA
67 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
68 * fixed race condition between disassociation event and group key
69 handshake to avoid getting stuck in incorrect state [Bug 261]
70 * fixed opportunistic key caching (proactive_key_caching)
73 * removed 'nai' and 'eappsk' network configuration variables that were
74 previously used for configuring user identity and key for EAP-PSK,
75 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
76 replacement for 'nai' (if old configuration used a separate
77 'identity' value, that would now be configured as
78 'anonymous_identity'). 'password' field is now used as the
79 replacement for 'eappsk' (it can also be set using hexstring to
80 present random binary data)
81 * removed '-w' command line parameter (wait for interface to be added,
82 if needed); cleaner way of handling this functionality is to use an
83 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
84 when an interface is added
85 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
86 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
87 indicating when new scan results become available
88 * added new ctrl_iface command, BSS, to allow scan results to be
89 fetched without hitting the message size limits (this command
90 can be used to iterate through the scan results one BSS at the time)
91 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
92 attributes in EAP-SIM Start/Response when using fast reauthentication
93 * fixed EAPOL not to end up in infinite loop when processing dynamic
94 WEP keys with IEEE 802.1X
95 * fixed problems in getting NDIS events from WMI on Windows 2000
98 * added support for Makefile builds to include debug-log-to-a-file
99 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
100 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
101 lengths properly to avoid potential crash caused by invalid messages
102 * added data structure for storing allocated buffers (struct wpabuf);
103 this does not affect wpa_supplicant usage, but many of the APIs
104 changed and various interfaces (e.g., EAP) is not compatible with old
106 * added support for protecting EAP-AKA/Identity messages with
107 AT_CHECKCODE (optional feature in RFC 4187)
108 * added support for protected result indication with AT_RESULT_IND for
109 EAP-SIM and EAP-AKA (phase1="result_ind=1")
110 * added driver_wext workaround for race condition between scanning and
111 association with drivers that take very long time to scan all
112 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
113 using a longer hardcoded timeout for the scan if the driver supports
114 notifications for scan completion (SIOCGIWSCAN event); this helps,
115 e.g., in cases where wpa_supplicant and madwifi driver ended up in
116 loop where the driver did not even try to associate
117 * stop EAPOL timer tick when no timers are in use in order to reduce
118 power consumption (no need to wake up the process once per second)
120 * added support for privilege separation (run only minimal part of
121 wpa_supplicant functionality as root and rest as unprivileged,
122 non-root process); see 'Privilege separation' in README for details;
123 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
125 * changed scan results data structure to include all information
126 elements to make it easier to support new IEs; old get_scan_result()
127 driver_ops is still supported for backwards compatibility (results
128 are converted internally to the new format), but all drivers should
129 start using the new get_scan_results2() to make them more likely to
130 work with new features
131 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
132 application, i.e., it does not require Qt3Support anymore; Windows
133 binary of wpa_gui.exe is now from this directory and only requires
134 QtCore4.dll and QtGui4.dll libraries
135 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
136 available as a separate package to make wpa_gui installation easier:
137 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
138 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
139 only shared key/password authentication is supported in this version
142 * added support for configuring password as NtPasswordHash
143 (16-byte MD4 hash of password) in hash:<32 hex digits> format
144 * added support for fallback from abbreviated TLS handshake to
145 full handshake when using EAP-FAST (e.g., due to an expired
147 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
148 draft (draft-ietf-emu-eap-gpsk-07.txt)
149 * added support for drivers that take care of RSN 4-way handshake
150 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
151 WPA_ALG_PMK in set_key)
152 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
153 .config); this version supports only ap_scan=2 mode and allow the
154 driver to take care of the 4-way handshake
155 * fixed a buffer overflow in parsing TSF from scan results when using
156 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
158 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
159 * fixed an integer overflow issue in the ASN.1 parser used by the
160 (experimental) internal TLS implementation to avoid a potential
162 * fixed a race condition with -W option (wait for a control interface
163 monitor before starting) that could have caused the first messages to
165 * added support for processing TNCC-TNCS-Messages to report
166 recommendation (allow/none/isolate) when using TNC [Bug 243]
169 * added network configuration parameter 'frequency' for setting
170 initial channel for IBSS (adhoc) networks
171 * added experimental IEEE 802.11r/D6.0 support
172 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
173 * updated EAP-PSK to use the IANA-allocated EAP type 47
174 * fixed EAP-PAX key derivation
175 * fixed EAP-PSK bit ordering of the Flags field
176 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
177 tunnelled identity request (previously, the identifier from the outer
178 method was used, not the tunnelled identifier which could be
180 * added support for fragmentation of outer TLS packets during Phase 2
181 of EAP-PEAP/TTLS/FAST
182 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
183 * added support for EAP-FAST authentication with inner methods that
184 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
185 for PAC provisioning)
186 * added support for authenticated EAP-FAST provisioning
187 * added support for configuring maximum number of EAP-FAST PACs to
188 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
189 * added support for storing EAP-FAST PACs in binary format
190 (fast_pac_format=binary in phase1 string)
191 * fixed dbus ctrl_iface to validate message interface before
192 dispatching to avoid a possible segfault [Bug 190]
193 * fixed PeerKey key derivation to use the correct PRF label
194 * updated Windows binary build to link against OpenSSL 0.9.8d and
195 added support for EAP-FAST
196 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
197 draft (draft-ietf-emu-eap-gpsk-04.txt)
198 * fixed EAP-AKA Notification processing to allow Notification to be
199 processed after AKA Challenge response has been sent
200 * updated to use IEEE 802.11w/D2.0 for management frame protection
202 * fixed EAP-TTLS implementation not to crash on use of freed memory
203 if TLS library initialization fails
204 * added support for EAP-TNC (Trusted Network Connect)
205 (this version implements the EAP-TNC method and EAP-TTLS changes
206 needed to run two methods in sequence (IF-T) and the IF-IMC and
207 IF-TNCCS interfaces from TNCC)
210 * added experimental, integrated TLSv1 client implementation with the
211 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
212 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
213 .config); this can be useful, e.g., if the target system does not
214 have a suitable TLS library and a minimal code size is required
215 (total size of this internal TLS/crypto code is bit under 50 kB on
216 x86 and the crypto code is shared by rest of the supplicant so some
217 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
218 * removed STAKey handshake since PeerKey handshake has replaced it in
219 IEEE 802.11ma and there are no known deployments of STAKey
220 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
221 draft (draft-ietf-emu-eap-gpsk-01.txt)
222 * added preliminary implementation of IEEE 802.11w/D1.0 (management
224 (Note: this requires driver support to work properly.)
225 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
226 * fixed Windows named pipes ctrl_iface to not stop listening for
227 commands if client program opens a named pipe and closes it
228 immediately without sending a command
229 * fixed USIM PIN status determination for the case that PIN is not
230 needed (this allows EAP-AKA to be used with USIM cards that do not
232 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
233 be used with cards that do not support file selection based on
235 * added support for matching the subjectAltName of the authentication
236 server certificate against multiple name components (e.g.,
237 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
238 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
239 affects IEEE 802.1X with dynamic WEP keys)
240 * changed ctrl_iface network configuration 'get' operations to not
241 return password/key material; if these fields are requested, "*"
242 will be returned if the password/key is set, but the value of the
243 parameter is not exposed
246 * added support for building Windows version with UNICODE defined
247 (wide-char functions)
248 * driver_ndis: fixed static WEP configuration to avoid race condition
249 issues with some NDIS drivers between association and setting WEP
251 * driver_ndis: added validation for IELength value in scan results to
252 avoid crashes when using buggy NDIS drivers [Bug 165]
253 * fixed Release|Win32 target in the Visual Studio project files
254 (previously, only Debug|Win32 target was set properly)
255 * changed control interface API call wpa_ctrl_pending() to allow it to
256 return -1 on error (e.g., connection lost); control interface clients
257 will need to make sure that they verify that the value is indeed >0
258 when determining whether there are pending messages
259 * added an alternative control interface backend for Windows targets:
260 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
261 control interface mechanism for Windows builds (previously, UDP to
263 * changed ctrl_interface configuration for UNIX domain sockets:
264 - deprecated ctrl_interface_group variable (it may be removed in
266 - allow both directory and group be configured with ctrl_interface
267 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
268 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
269 case when group is not changed
270 * added support for controlling more than one interface per process in
272 * added a workaround for a case where the AP is using unknown address
273 (e.g., MAC address of the wired interface) as the source address for
274 EAPOL-Key frames; previously, that source address was used as the
275 destination for EAPOL-Key frames and in key derivation; now, BSSID is
276 used even if the source address does not match with it
277 (this resolves an interoperability issue with Thomson SpeedTouch 580)
278 * added a workaround for UDP-based control interface (which was used in
279 Windows builds before this release) to prevent packets with forged
280 addresses from being accepted as local control requests
281 * removed ndis_events.cpp and possibility of using external
282 ndis_events.exe; C version (ndis_events.c) is fully functional and
283 there is no desire to maintain two separate versions of this
285 * ndis_events: Changed NDIS event notification design to use WMI to
286 learn the adapter description through Win32_PnPEntity class; this
287 should fix some cases where the adapter name was not recognized
288 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
290 * fixed selection of the first network in ap_scan=2 mode; previously,
291 wpa_supplicant could get stuck in SCANNING state when only the first
292 network for enabled (e.g., after 'wpa_cli select_network 0')
293 * winsvc: added support for configuring ctrl_interface parameters in
294 registry (ctrl_interface string value in
295 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
296 required to enable control interface (previously, this was hardcoded
298 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
299 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
302 * fixed build with CONFIG_STAKEY=y [Bug 143]
303 * added support for doing MLME (IEEE 802.11 management frame
304 processing) in wpa_supplicant when using Devicescape IEEE 802.11
305 stack (wireless-dev.git tree)
306 * added a new network block configuration option, fragment_size, to
307 configure the maximum EAP fragment size
308 * driver_ndis: Disable WZC automatically for the selected interface to
309 avoid conflicts with two programs trying to control the radio; WZC
310 will be re-enabled (if it was enabled originally) when wpa_supplicant
312 * added an experimental TLSv1 client implementation
313 (CONFIG_TLS=internal) that can be used instead of an external TLS
314 library, e.g., to reduce total size requirement on systems that do
315 not include any TLS library by default (this is not yet complete;
316 basic functionality is there, but certificate validation is not yet
318 * added PeerKey handshake implementation for IEEE 802.11e
319 direct link setup (DLS) to replace STAKey handshake
320 * fixed WPA PSK update through ctrl_iface for the case where the old
321 PSK was derived from an ASCII passphrase and the new PSK is set as
322 a raw PSK (hex string)
323 * added new configuration option for identifying which network block
324 was used (id_str in wpa_supplicant.conf; included on
325 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
326 variable in wpa_cli action scripts; in addition WPA_ID variable is
327 set to the current unique identifier that wpa_supplicant assigned
328 automatically for the network and that can be used with
329 GET_NETWORK/SET_NETWORK ctrl_iface commands)
330 * wpa_cli action script is now called only when the connect/disconnect
331 status changes or when associating with a different network
332 * fixed configuration parser not to remove CCMP from group cipher list
333 if WPA-None (adhoc) is used (pairwise=NONE in that case)
334 * fixed integrated NDIS events processing not to hang the process due
335 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
336 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
337 draft-clancy-emu-eap-shared-secret-00.txt)
338 * added Microsoft Visual Studio 2005 solution and project files for
339 build wpa_supplicant for Windows (see vs2005 subdirectory)
340 * eloop_win: fixed unregistration of Windows events
341 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
342 at the end of RSN pre-authentication and added unregistration of
343 a Windows event to avoid getting eloop_win stuck with an invalid
345 * driver_ndis: added support for selecting AP based on BSSID
346 * added new environmental variable for wpa_cli action scripts:
347 WPA_CTRL_DIR is the current control interface directory
348 * driver_ndis: added support for using NDISUIO instead of WinPcap for
349 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
350 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
351 wpa_supplicant without requiring WinPcap; note that using NDISUIO
352 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
353 only one application to open the device
354 * changed NDIS driver naming to only include device GUID, e.g.,
355 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
356 specific \Device\NPF_ prefix before the GUID; the prefix is still
357 allowed for backwards compatibility, but it is not required anymore
358 when specifying the interface
359 * driver_ndis: re-initialize driver interface is the adapter is removed
360 and re-inserted [Bug 159]
361 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
362 big endian hosts [Bug 146]
365 * fixed EAP-GTC response to include correct user identity when run as
366 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
367 * driver_ndis: Fixed encryption mode configuration for unencrypted
368 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
369 refused to associate with open networks) [Bug 106]
370 * driver_ndis: use BSSID OID polling to detect when IBSS network is
371 formed even when ndis_events code is included since some NDIS drivers
372 do not generate media connect events in IBSS mode
373 * config_winreg: allow global ctrl_interface parameter to be configured
375 * config_winreg: added support for saving configuration data into
377 * added support for controlling network device operational state
378 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
379 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
380 that can use this information)
381 * driver_wext: added support for WE-21 change to SSID configuration
382 * driver_wext: fixed privacy configuration for static WEP keys mode
384 * added an optional driver_ops callback for MLME-SETPROTECTION.request
386 * added support for EAP-SAKE (no EAP method number allocated yet, so
387 this is using the same experimental type 255 as EAP-PSK)
388 * added support for dynamically loading EAP methods (.so files) instead
389 of requiring them to be statically linked in; this is disabled by
390 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
394 * do not try to use USIM APDUs when initializing PC/SC for SIM card
395 access for a network that has not enabled EAP-AKA
396 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
397 v0.5.1 due to the new support for expanded EAP types)
398 * added support for generating EAP Expanded Nak
399 * try to fetch scan results once before requesting new scan when
400 starting up in ap_scan=1 mode (this can speed up initial association
401 a lot with, e.g., madwifi-ng driver)
402 * added support for receiving EAPOL frames from a Linux bridge
403 interface (-bbr0 on command line)
404 * fixed EAPOL re-authentication for sessions that used PMKSA caching
405 * changed EAP method registration to use a dynamic list of methods
406 instead of a static list generated at build time
407 * fixed PMKSA cache deinitialization not to use freed memory when
408 removing PMKSA entries
409 * fixed a memory leak in EAP-TTLS re-authentication
410 * reject WPA/WPA2 message 3/4 if it does not include any valid
412 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
413 if the driver does not support SIOCSIWAUTH
416 * driver_test: added better support for multiple APs and STAs by using
417 a directory with sockets that include MAC address for each device in
418 the name (driver_param=test_dir=/tmp/test)
419 * added support for EAP expanded type (vendor specific EAP methods)
420 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
421 option can be changed if needed
422 * wpa_cli/wpa_gui: skip non-socket files in control directory when
423 using UNIX domain sockets; this avoids selecting an incorrect
424 interface (e.g., a PID file could be in this directory, even though
425 use of this directory for something else than socket files is not
427 * fixed TLS library deinitialization after RSN pre-authentication not
428 to disable TLS library for normal authentication
429 * driver_wext: Remove null-termination from SSID length if the driver
430 used it; some Linux drivers do this and they were causing problems in
431 wpa_supplicant not finding matching configuration block. This change
432 would break a case where the SSID actually ends in '\0', but that is
433 not likely to happen in real use.
434 * fixed PMKSA cache processing not to trigger deauthentication if the
435 current PMKSA cache entry is replaced with a valid new entry
436 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
437 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
440 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
441 * added experimental STAKey handshake implementation for IEEE 802.11e
442 direct link setup (DLS); note: this is disabled by default in both
443 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
445 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
446 decrypt AT_ENCR_DATA attributes correctly
447 * fixed EAP-AKA to allow resynchronization within the same session
448 * made code closer to ANSI C89 standard to make it easier to port to
449 other C libraries and compilers
450 * started moving operating system or C library specific functions into
451 wrapper functions defined in os.h and implemented in os_*.c to make
453 * wpa_supplicant can now be built with Microsoft Visual C++
454 (e.g., with the freely available Toolkit 2003 version or Visual
455 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
456 example makefile for nmake
457 * added support for using Windows registry for command line parameters
458 (CONFIG_MAIN=main_winsvc) and configuration data
459 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
460 contents; this version can be run both as a Windows service and as a
461 normal application; 'wpasvc.exe app' to start as applicant,
462 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
463 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
465 * made it possible to link ndis_events.exe functionality into
466 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
467 * added better support for multiple control interface backends
468 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
469 * fixed PC/SC code to use correct length for GSM AUTH command buffer
470 and to not use pioRecvPci with SCardTransmit() calls; these were not
471 causing visible problems with pcsc-lite, but Windows Winscard.dll
472 refused the previously used parameters; this fixes EAP-SIM and
473 EAP-AKA authentication using SIM/USIM card under Windows
474 * added new event loop implementation for Windows using
475 WaitForMultipleObject() instead of select() in order to allow waiting
476 for non-socket objects; this can be selected with
477 CONFIG_ELOOP=eloop_win in .config
478 * added support for selecting l2_packet implementation in .config
479 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
480 winpcap, freebsd, none)
481 * added new l2_packet implementation for WinPcap
482 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
483 reduce latency in EAPOL receive processing from about 100 ms to about
485 * added support for EAP-FAST key derivation using other ciphers than
486 RC4-128-SHA for authentication and AES128-SHA for provisioning
487 * added support for configuring CA certificate as DER file and as a
489 * fixed private key configuration as configuration blob and added
490 support for using PKCS#12 as a blob
491 * tls_gnutls: added support for using PKCS#12 files; added support for
493 * added support for loading trusted CA certificates from Windows
494 certificate store: ca_cert="cert_store://<name>", where <name> is
495 likely CA (Intermediate CA certificates) or ROOT (root certificates)
496 * added C version of ndis_events.cpp and made it possible to build this
497 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
498 easily on cross-compilation builds
499 * added wpasvc.exe into Windows binary release; this is an alternative
500 version of wpa_supplicant.exe with configuration backend using
501 Windows registry and with the entry point designed to run as a
503 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
504 wpasvc.exe and removed this additional tool from the Windows binary
505 release since it is not needed anymore
506 * load winscard.dll functions dynamically when building with MinGW
507 since MinGW does not yet include winscard library
509 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
510 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
511 and WinPcap to receive frames sent to PAE group address
512 * disable EAP state machine when IEEE 802.1X authentication is not used
513 in order to get rid of bogus "EAP failed" messages
514 * fixed OpenSSL error reporting to go through all pending errors to
515 avoid confusing reports of old errors being reported at later point
517 * fixed configuration file updating to not write empty variables
518 (e.g., proto or key_mgmt) that the file parser would not accept
519 * fixed ADD_NETWORK ctrl_iface command to use the same default values
520 for variables as empty network definitions read from config file
522 * fixed EAP state machine to not discard EAP-Failure messages in many
523 cases (e.g., during TLS handshake)
524 * fixed a infinite loop in private key reading if the configured file
525 cannot be parsed successfully
526 * driver_madwifi: added support for madwifi-ng
527 * wpa_gui: do not display password/PSK field contents
528 * wpa_gui: added CA certificate configuration
529 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
530 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
531 the new AP is using different WPA/RSN IE
532 * use longer timeout for IEEE 802.11 association to avoid problems with
533 drivers that may take more than five second to associate
536 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
537 RSN IE, but WPA IE would match with wpa_supplicant configuration
538 * added support for named configuration blobs in order to avoid having
539 to use file system for external files (e.g., certificates);
540 variables can be set to "blob://<blob name>" instead of file path to
541 use a named blob; supported fields: pac_file, client_cert,
543 * fixed RSN pre-authentication (it was broken in the clean up of WPA
544 state machine interface in v0.4.5)
545 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
546 sure the driver configures broadcast decryption correctly
547 * added ca_path (and ca_path2) configuration variables that can be used
548 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
549 system-wide trusted CA list
550 * added support for starting wpa_supplicant without a configuration
551 file (-C argument must be used to set ctrl_interface parameter for
552 this case; in addition, -p argument can be used to provide
553 driver_param; these new arguments can also be used with a
554 configuration to override the values from the configuration)
555 * added global control interface that can be optionally used for adding
556 and removing network interfaces dynamically (-g command line argument
557 for both wpa_supplicant and wpa_cli) without having to restart
558 wpa_supplicant process
560 - try to save configuration whenever something is modified
561 - added WEP key configuration
562 - added possibility to edit the current network configuration
563 * driver_ndis: fixed driver polling not to increase frequency on each
564 received EAPOL frame due to incorrectly cancelled timeout
565 * added simple configuration file examples (in examples subdirectory)
566 * fixed driver_wext.c to filter wireless events based on ifindex to
567 avoid interfaces receiving events from other interfaces
568 * delay sending initial EAPOL-Start couple of seconds to speed up
569 authentication for the most common case of Authenticator starting
570 EAP authentication immediately after association
573 * added a workaround for clearing keys with ndiswrapper to allow
574 roaming from WPA enabled AP to plaintext one
575 * added docbook documentation (doc/docbook) that can be used to
576 generate, e.g., man pages
577 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
578 PF_PACKET in order to prepare for network devices that do not use
579 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
580 * use receipt of EAPOL-Key frame as a lower layer success indication
581 for EAP state machine to allow recovery from dropped EAP-Success
583 * cleaned up internal EAPOL frame processing by not including link
584 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
585 header is added only when transmitted the frame; this makes it easier
586 to use wpa_supplicant on link layers that use different header than
588 * updated EAP-PSK to use draft 9 by default since this can now be
589 tested with hostapd; removed support for draft 3, including
590 server_nai configuration option from network blocks
591 * driver_wired: add PAE address to the multicast address list in order
592 to be able to receive EAPOL frames with drivers that do not include
593 these multicast addresses by default
594 * driver_wext: add support for WE-19
595 * added support for multiple configuration backends (CONFIG_BACKEND
596 option); currently, only 'file' is supported (i.e., the format used
597 in wpa_supplicant.conf)
598 * added support for updating configuration ('wpa_cli save_config');
599 this is disabled by default and can be enabled with global
600 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
601 and wpa_gui to store the configuration changes in a permanent store
602 * added GET_NETWORK ctrl_iface command
603 (e.g., 'wpa_cli get_network 0 ssid')
606 * replaced OpenSSL patch for EAP-FAST support
607 (openssl-tls-extensions.patch) with a more generic and correct
608 patch (the new patch is not compatible with the previous one, so the
609 OpenSSL library will need to be patched with the new patch in order
610 to be able to build wpa_supplicant with EAP-FAST support)
611 * added support for using Windows certificate store (through CryptoAPI)
612 for client certificate and private key operations (EAP-TLS)
613 (see wpa_supplicant.conf for more information on how to configure
614 this with private_key)
615 * ported wpa_gui to Windows
616 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
617 built with the open source version of the Qt4 for Windows
618 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
619 with drivers that do not support WPA
620 * ndis_events: fixed Windows 2000 support
621 * added support for enabling/disabling networks from the list of all
622 configured networks ('wpa_cli enable_network <network id>' and
623 'wpa_cli disable_network <network id>')
624 * added support for adding and removing network from the current
625 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
626 <network id>'); added networks are disabled by default and they can
627 be enabled with enable_network command once the configuration is done
628 for the new network; note: configuration file is not yet updated, so
629 these new networks are lost when wpa_supplicant is restarted
630 * added support for setting network configuration parameters through
631 the control interface, for example:
632 wpa_cli set_network 0 ssid "\"my network\""
633 * fixed parsing of strings that include both " and # within double
634 quoted area (e.g., "start"#end")
635 * added EAP workaround for PEAP session resumption: allow outer,
636 i.e., not tunneled, EAP-Success to terminate session since; this can
637 be disabled with eap_workaround=0
638 (this was allowed for PEAPv1 before, but now it is also allowed for
639 PEAPv0 since at least one RADIUS authentication server seems to be
640 doing this for PEAPv0, too)
641 * wpa_gui: added preliminary support for adding new networks to the
642 wpa_supplicant configuration (double click on the scan results to
643 open network configuration)
646 * removed interface for external EAPOL/EAP supplicant (e.g.,
647 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
648 anymore and is unlikely to be used by anyone
649 * driver_ndis: fixed WinPcap 3.0 support
650 * fixed build with CONFIG_DNET_PCAP=y on Linux
651 * l2_packet: moved different implementations into separate files
655 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
656 (note: ipw2100-1.1.0 is likely to require an update to work with
658 * added support for using ap_scan=2 mode with multiple network blocks;
659 wpa_supplicant will go through the networks one by one until the
660 driver reports a successful association; this uses the same order for
661 networks as scan_ssid=1 scans, i.e., the priority field is ignored
662 and the network block order in the file is used instead
663 * fixed a potential issue in RSN pre-authentication ending up using
664 freed memory if pre-authentication times out
665 * added support for matching alternative subject name extensions of the
666 authentication server certificate; new configuration variables
667 altsubject_match and altsubject_match2
668 * driver_ndis: added support for IEEE 802.1X authentication with wired
670 * added support for querying private key password (EAP-TLS) through the
671 control interface (wpa_cli/wpa_gui) if one is not included in the
673 * driver_broadcom: fixed couple of memory leaks in scan result
675 * EAP-PAX is now registered as EAP type 46
676 * fixed EAP-PAX MAC calculation
677 * fixed EAP-PAX CK and ICK key derivation
678 * added support for using password with EAP-PAX (as an alternative to
679 entering key with eappsk); SHA-1 hash of the password will be used as
681 * added support for arbitrary driver interface parameters through the
682 configuration file with a new driver_param field; this adds a new
683 driver_ops function set_param()
684 * added possibility to override l2_packet module with driver interface
685 API (new send_eapol handler); this can be used to implement driver
686 specific TX/RX functions for EAPOL frames
687 * fixed ctrl_interface_group processing for the case where gid is
688 entered as a number, not group name
689 * driver_test: added support for testing hostapd with wpa_supplicant
690 by using test driver interface without any kernel drivers or network
694 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
695 packets to be encrypted; this was apparently broken by the changed
696 ioctl order in v0.4.0
697 * driver_madwifi: added preliminary support for compiling against 'BSD'
698 branch of madwifi CVS tree
699 * added support for EAP-MSCHAPv2 password retries within the same EAP
700 authentication session
701 * added support for password changes with EAP-MSCHAPv2 (used when the
702 password has expired)
703 * added support for reading additional certificates from PKCS#12 files
704 and adding them to the certificate chain
705 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
707 * fixed a possible double free in EAP-TTLS fast-reauthentication when
708 identity or password is entered through control interface
709 * display EAP Notification messages to user through control interface
710 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
711 * added GUI version of wpa_cli, wpa_gui; this is not build
712 automatically with 'make'; use 'make wpa_gui' to build (this requires
713 Qt development tools)
714 * added 'disconnect' command to control interface for setting
715 wpa_supplicant in state where it will not associate before
716 'reassociate' command has been used
717 * added support for selecting a network from the list of all configured
718 networks ('wpa_cli select_network <network id>'; this disabled all
719 other networks; to re-enable, 'wpa_cli select_network any')
720 * added support for getting scan results through control interface
721 * added EAP workaround for PEAPv1 session resumption: allow outer,
722 i.e., not tunneled, EAP-Success to terminate session since; this can
723 be disabled with eap_workaround=0
725 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
726 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
727 used to reduce the size of the wpa_supplicant considerably if
728 debugging code is not needed
729 * fixed EAPOL-Key validation to drop packets with invalid Key Data
730 Length; such frames could have crashed wpa_supplicant due to buffer
732 * added support for wired authentication (IEEE 802.1X on wired
733 Ethernet); driver interface 'wired'
734 * obsoleted set_wpa() handler in the driver interface API (it can be
735 replaced by moving enable/disable functionality into init()/deinit())
736 (calls to set_wpa() are still present for backwards compatibility,
737 but they may be removed in the future)
738 * driver_madwifi: fixed association in plaintext mode
739 * modified the EAP workaround that accepts EAP-Success with incorrect
740 Identifier to be even less strict about verification in order to
741 interoperate with some authentication servers
742 * added support for sending TLS alerts
743 * added support for 'any' SSID wildcard; if ssid is not configured or
744 is set to an empty string, any SSID will be accepted for non-WPA AP
745 * added support for asking PIN (for SIM) from frontends (e.g.,
746 wpa_cli); if a PIN is needed, but not included in the configuration
747 file, a control interface request is sent and EAP processing is
748 delayed until the PIN is available
749 * added support for using external devices (e.g., a smartcard) for
750 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
751 new wpa_supplicant.conf variables:
752 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
753 - network: engine, engine_id, key_id
754 * added experimental support for EAP-PAX
755 * added monitor mode for wpa_cli (-a<path to a program to run>) that
756 allows external commands (e.g., shell scripts) to be run based on
757 wpa_supplicant events, e.g., when authentication has been completed
758 and data connection is ready; other related wpa_cli arguments:
759 -B (run in background), -P (write PID file); wpa_supplicant has a new
760 command line argument (-W) that can be used to make it wait until a
761 control interface command is received in order to avoid missing
763 * added support for opportunistic WPA2 PMKSA key caching (disabled by
764 default, can be enabled with proactive_key_caching=1)
765 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
766 Authenticator rejects PMKSA caching attempt and the driver is not
767 using assoc_info events
768 * added -P<pid file> argument for wpa_supplicant to write the current
769 process id into a file
771 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
772 * added new phase1 option parameter, include_tls_length=1, to force
773 wpa_supplicant to add TLS Message Length field to all TLS messages
774 even if the packet is not fragmented; this may be needed with some
775 authentication servers
776 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
777 using drivers that take care of AP selection (e.g., when using
779 * fixed reprocessing of pending request after ctrl_iface requests for
780 identity/password/otp
781 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
782 EAP-PEAP and EAP-TTLS
783 * all drivers using driver_wext: set interface up and select Managed
784 mode when starting wpa_supplicant; set interface down when exiting
785 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
786 ipw2100 and ipw2200; please note that this also changed the
787 configuration variable in .config to CONFIG_DRIVER_IPW
790 * fixed a busy loop introduced in v0.3.5 for scan result processing
791 when no matching AP is found
794 * added a workaround for an interoperability issue with a Cisco AP
796 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
797 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
798 retransmission of dropped frames)
799 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
800 (e.g., segfault when processing EAPOL-Key frames)
801 * fixed EAP workaround and fast reauthentication configuration for
802 RSN pre-authentication; previously these were disabled and
803 pre-authentication would fail if the used authentication server
804 requires EAP workarounds
805 * added support for blacklisting APs that fail or timeout
806 authentication in ap_scan=1 mode so that all APs are tried in cases
807 where the ones with strongest signal level are failing authentication
808 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
809 authentication attempt
810 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
811 in the previous authentication (previously, only Phase 1 success was
815 * added preliminary support for IBSS (ad-hoc) mode configuration
816 (mode=1 in network block); this included a new key_mgmt mode
817 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
818 key management; see wpa_supplicant.conf for more details and an
819 example on how to configure this (note: this is currently implemented
820 only for driver_hostapd.c, but the changes should be trivial to add
821 in associate() handler for other drivers, too (assuming the driver
823 * added preliminary port for native Windows (i.e., no cygwin) using
827 * added optional support for GNU Readline and History Libraries for
828 wpa_cli (CONFIG_READLINE)
829 * cleaned up EAP state machine <-> method interface and number of
830 small problems with error case processing not terminating on
831 EAP-Failure but waiting for timeout
832 * added couple of workarounds for interoperability issues with a
833 Cisco AP when using WPA2
834 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
835 Note: This requires a patch for openssl to add support for TLS
836 extensions and number of workarounds for operations without
837 certificates. Proof of concept type of experimental patch is
838 included in openssl-tls-extensions.patch.
841 * fixed private key loading for cases where passphrase is not set
842 * fixed Windows/cygwin L2 packet handler freeing; previous version
843 could cause a segfault when RSN pre-authentication was completed
844 * added support for PMKSA caching with drivers that generate RSN IEs
845 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
846 but similar code can be easily added to driver_ndiswrapper.c once
847 ndiswrapper gets full support for RSN PMKSA caching
848 * improved recovery from PMKID mismatches by requesting full EAP
849 authentication in case of failed PMKSA caching attempt
850 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
851 (this requires that ndis_events is ran while wpa_supplicant is
853 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
854 * added support for driver interfaces to replace the interface name
855 based on driver/OS specific mapping, e.g., in case of driver_ndis,
856 this allows the beginning of the adapter description to be used as
858 * added support for CR+LF (Windows-style) line ends in configuration
860 * driver_ndis: enable radio before starting scanning, disable radio
862 * modified association event handler to set portEnabled = FALSE before
863 clearing port Valid in order to reset EAP state machine and avoid
864 problems with new authentication getting ignored because of state
865 machines ending up in AUTHENTICATED/SUCCESS state based on old
867 * added support for driver events to add PMKID candidates in order to
868 allow drivers to give priority to most likely roaming candidates
869 * driver_hostap: moved PrivacyInvoked configuration to associate()
870 function so that this will not be set for plaintext connections
871 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
872 interface can distinguish plaintext and IEEE 802.1X (no WPA)
874 * fixed static WEP key configuration to use broadcast/default type for
875 all keys (previously, the default TX key was configured as pairwise/
877 * driver_ndis: added legacy WPA capability detection for non-WPA2
879 * added support for setting static WEP keys for IEEE 802.1X without
880 dynamic WEP keying (eapol_flags=0)
883 * added support for reading PKCS#12 (PFX) files (as a replacement for
884 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
885 * fixed compilation with CONFIG_PCSC=y
886 * added new ap_scan mode, ap_scan=2, for drivers that take care of
887 association, but need to be configured with security policy and SSID,
888 e.g., ndiswrapper and NDIS driver; this mode should allow such
889 drivers to work with hidden SSIDs and optimized roaming; when
890 ap_scan=2 is used, only the first network block in the configuration
891 file is used and this configuration should have explicit security
892 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
893 group, proto variables
894 * added experimental port of wpa_supplicant for Windows
895 - driver_ndis.c driver interface (NDIS OIDs)
896 - currently, this requires cygwin and WinPcap
897 - small utility, win_if_list, can be used to get interface name
898 * control interface can now be removed at build time; add
899 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
900 * optional Xsupplicant interface can now be removed at build time;
901 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
902 * added auth_alg to driver interface associate() parameters to make it
903 easier for drivers to configure authentication algorithm as part of
906 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
907 * driver_broadcom: added new driver interface for Broadcom wl.o driver
908 (a generic driver for Broadcom IEEE 802.11a/g cards)
909 * wpa_cli: fixed parsing of -p <path> command line argument
910 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
911 ACK, not tunneled EAP-Success (of which only the first byte was
912 actually send due to a bug in previous code); this seems to
913 interoperate with most RADIUS servers that implements PEAPv1
914 * PEAPv1: added support for terminating PEAP authentication on tunneled
915 EAP-Success message; this can be configured by adding
916 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
917 (some RADIUS servers require this whereas others require a tunneled
919 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
920 the old label for key derivation; previously, the default was 1,
921 but it looks like most existing PEAPv1 implementations use the old
922 label which is thus more suitable default option
923 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
924 * fixed parsing of wep_tx_keyidx
925 * added support for configuring list of allowed Phase 2 EAP types
926 (for both EAP-PEAP and EAP-TTLS) instead of only one type
927 * added support for configuring IEEE 802.11 authentication algorithm
928 (auth_alg; mainly for using Shared Key authentication with static
930 * added support for EAP-AKA (with UMTS SIM)
931 * fixed couple of errors in PCSC handling that could have caused
932 random-looking errors for EAP-SIM
933 * added support for EAP-SIM pseudonyms and fast re-authentication
934 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
936 * added support for EAP-SIM with two challanges
937 (phase1="sim_min_num_chal=3" can be used to require three challenges)
938 * added support for configuring DH/DSA parameters for an ephemeral DH
939 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
940 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
941 and optional DH key exchange to achieve forward secracy with RSA keys
942 * added support for matching subject of the authentication server
943 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
944 configuration variables subject_match and subject_match2
945 * changed SSID configuration in driver_wext.c (used by many driver
946 interfaces) to use ssid_len+1 as the length for SSID since some Linux
948 * fixed couple of unaligned reads in scan result parsing to fix WPA
949 connection on some platforms (e.g., ARM)
950 * added driver interface for Intel ipw2100 driver
951 * added support for LEAP with WPA
952 * added support for larger scan results report (old limit was 4 kB of
953 data, i.e., about 35 or so APs) when using Linux wireless extensions
955 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
956 only if there is a PMKSA cache entry for the current AP
957 * fixed error handling for case where reading of scan results fails:
958 must schedule a new scan or wpa_supplicant will remain waiting
960 * changed debug output to remove shared password/key material by
961 default; all key information can be included with -K command line
962 argument to match the previous behavior
963 * added support for timestamping debug log messages (disabled by
964 default, can be enabled with -t command line argument)
965 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
966 if keys are not configured to be used; this fixes IEEE 802.1X mode
967 with drivers that use this information to configure whether Privacy
968 bit can be in Beacon frames (e.g., ndiswrapper)
969 * avoid clearing driver keys if no keys have been configured since last
970 key clear request; this seems to improve reliability of group key
971 handshake for ndiswrapper & NDIS driver which seems to be suffering
972 of some kind of timing issue when the keys are cleared again after
974 * changed driver interface API:
975 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
976 version is being used (now, this is set to 2; previously, it was
978 - pass pointer to private data structure to all calls
979 - the new API is not backwards compatible; all in-tree driver
980 interfaces has been converted to the new API
981 * added support for controlling multiple interfaces (radios) per
982 wpa_supplicant process; each interface needs to be listed on the
983 command line (-c, -i, -D arguments) with -N as a separator
984 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
985 * added a workaround for EAP servers that incorrectly use same Id for
986 sequential EAP packets
987 * changed libpcap/libdnet configuration to use .config variable,
988 CONFIG_DNET_PCAP, instead of requiring Makefile modification
989 * improved downgrade attack detection in IE verification of msg 3/4:
990 verify both WPA and RSN IEs, if present, not only the selected one;
991 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
992 Probe Response frame, and RSN is enabled in wpa_supplicant
994 * fixed WPA msg 3/4 processing to allow Key Data field contain other
995 IEs than just one WPA IE
996 * added support for FreeBSD and driver interface for the BSD net80211
997 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
998 required kernel mods have not yet been committed
999 * made EAP workarounds configurable; enabled by default, can be
1000 disabled with network block option eap_workaround=0
1002 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
1003 * resolved couple of interoperability issues with EAP-PEAPv1 and
1004 Phase 2 (inner EAP) fragment reassembly
1005 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
1006 AP is using non-zero key index for the unicast key and key index zero
1007 for the broadcast key
1008 * driver_hostap: fixed IEEE 802.1X WEP key updates and
1009 re-authentication by allowing unencrypted EAPOL frames when not using
1011 * added a new driver interface, 'wext', which uses only standard,
1012 driver independent functionality in Linux wireless extensions;
1013 currently, this can be used only for non-WPA IEEE 802.1X mode, but
1014 eventually, this is to be extended to support full WPA/WPA2 once
1015 Linux wireless extensions get support for this
1016 * added support for mode in which the driver is responsible for AP
1017 scanning and selection; this is disabled by default and can be
1018 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
1019 this mode can be used, e.g., with generic 'wext' driver interface to
1020 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
1021 supporting wireless extensions.
1022 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
1023 operation with an AP that does not include SSID in the Beacon frames)
1024 * added support for new EAP authentication methods:
1025 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
1026 * added support for asking one-time-passwords from frontends (e.g.,
1027 wpa_cli); this 'otp' command works otherwise like 'password' command,
1028 but the password is used only once and the frontend will be asked for
1029 a new password whenever a request from authenticator requires a
1030 password; this can be used with both EAP-OTP and EAP-GTC
1031 * changed wpa_cli to automatically re-establish connection so that it
1032 does not need to be re-started when wpa_supplicant is terminated and
1034 * improved user data (identity/password/otp) requests through
1035 frontends: process pending EAPOL packets after getting new
1036 information so that full authentication does not need to be
1037 restarted; in addition, send pending requests again whenever a new
1038 frontend is attached
1039 * changed control frontends to use a new directory for socket files to
1040 make it easier for wpa_cli to automatically select between interfaces
1041 and to provide access control for the control interface;
1042 wpa_supplicant.conf: ctrl_interface is now a path
1043 (/var/run/wpa_supplicant is the recommended path) and
1044 ctrl_interface_group can be used to select which group gets access to
1045 the control interface;
1046 wpa_cli: by default, try to connect to the first interface available
1047 in /var/run/wpa_supplicant; this path can be overriden with -p option
1048 and an interface can be selected with -i option (i.e., in most common
1049 cases, wpa_cli does not need to get any arguments)
1050 * added support for LEAP
1051 * added driver interface for Linux ndiswrapper
1052 * added priority option for network blocks in the configuration file;
1053 this allows networks to be grouped based on priority (the scan
1054 results are searched for matches with network blocks in this order)
1057 * sort scan results to improve AP selection
1058 * fixed control interface socket removal for some error cases
1059 * improved scan requesting and authentication timeout
1060 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1062 * PEAP version can now be forced with phase1="peapver=<ver>"
1063 (mostly for testing; by default, the highest version supported by
1064 both the Supplicant and Authentication Server is selected
1066 * added support for madwifi driver (Atheros ar521x)
1067 * added a workaround for cases where AP sets Install Tx/Rx bit for
1068 WPA Group Key messages when pairwise keys are used (without this,
1069 the Group Key would be used for Tx and the AP would drop frames
1071 * added GSM SIM/USIM interface for GSM authentication algorithm for
1072 EAP-SIM; this requires pcsc-lite
1073 * added support for ATMEL AT76C5XXx driver
1074 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1075 does not include key data in the EAPOL-Key frame (i.e., part of
1076 EAP keying material is used as data encryption key)
1077 * added support for using plaintext and static WEP networks
1081 * added support for new EAP authentication methods:
1082 EAP-TTLS/EAP-MD5-Challenge
1084 EAP-TTLS/EAP-MSCHAPv2
1092 EAP-PEAP/MD5-Challenge
1094 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1095 * added support for anonymous identity (to be used when identity is
1096 sent in plaintext; real identity will be used within TLS protected
1097 tunnel (e.g., with EAP-TTLS)
1098 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1099 * added support for requesting identity and password information using
1100 control interface; in other words, the password for EAP-PEAP or
1101 EAP-TTLS does not need to be included in the configuration file since
1102 a frontand (e.g., wpa_cli) can ask it from the user
1103 * improved RSN pre-authentication to use a candidate list and process
1104 all candidates from each scan; not only one per scan
1105 * fixed RSN IE and WPA IE capabilities field parsing
1106 * ignore Tx bit in GTK IE when Pairwise keys are used
1107 * avoid making new scan requests during IEEE 802.1X negotiation
1108 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1109 with TLS support (this replaces the included implementation with
1110 library code to save about 8 kB since the library code is needed
1112 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1113 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1116 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1118 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1119 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1120 - EAP-MD5 (cannot be used with WPA-RADIUS)
1121 [draft-ietf-eap-rfc2284bis-09.txt]
1122 - EAP-TLS [RFC 2716]
1123 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1124 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1125 [draft-kamath-pppext-eap-mschapv2-00.txt]
1126 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1127 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1128 - new configuration file options: eap, identity, password, ca_cert,
1129 client_cert, privatekey, private_key_passwd
1130 - Xsupplicant is not required anymore, but it can be used by
1131 disabling the internal IEEE 802.1X Supplicant with -e command line
1133 - this code is not included in the default build; Makefile need to
1134 be edited for this (uncomment lines for selected functionality)
1135 - EAP-TLS and EAP-PEAP require openssl libraries
1136 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1137 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1138 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1139 EAPOL-Key frames instead of WPA key handshakes)
1140 * added support for IEEE 802.11i/RSN (WPA2)
1141 - improved PTK Key Handshake
1142 - PMKSA caching, pre-authentication
1143 * fixed wpa_supplicant to ignore possible extra data after WPA
1144 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1145 TPTK' error from message 3 of 4-Way Handshake in case the AP
1146 includes extra data after the EAPOL-Key)
1147 * added interface for external programs (frontends) to control
1149 - CLI example (wpa_cli) with interactive mode and command line
1151 - replaced SIGUSR1 status/statistics with the new control interface
1152 * made some feature compile time configurable
1153 - .config file for make
1154 - driver interfaces (hostap, hermes, ..)
1155 - EAPOL/EAP functions
1158 * Initial version of wpa_supplicant
