1 ChangeLog for wpa_supplicant
4 * added support for EAP Sequences in EAP-FAST Phase 2
5 * added support for using TNC with EAP-FAST
6 * added driver_ps3 for the PS3 Linux wireless driver
9 * removed 'nai' and 'eappsk' network configuration variables that were
10 previously used for configuring user identity and key for EAP-PSK,
11 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
12 replacement for 'nai' (if old configuration used a separate
13 'identity' value, that would now be configured as
14 'anonymous_identity'). 'password' field is now used as the
15 replacement for 'eappsk' (it can also be set using hexstring to
16 present random binary data)
17 * removed '-w' command line parameter (wait for interface to be added,
18 if needed); cleaner way of handling this functionality is to use an
19 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
20 when an interface is added
21 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
22 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
23 indicating when new scan results become available
24 * added new ctrl_iface command, BSS, to allow scan results to be
25 fetched without hitting the message size limits (this command
26 can be used to iterate through the scan results one BSS at the time)
27 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
28 attributes in EAP-SIM Start/Response when using fast reauthentication
29 * fixed EAPOL not to end up in infinite loop when processing dynamic
30 WEP keys with IEEE 802.1X
31 * fixed problems in getting NDIS events from WMI on Windows 2000
34 * added support for Makefile builds to include debug-log-to-a-file
35 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
36 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
37 lengths properly to avoid potential crash caused by invalid messages
38 * added data structure for storing allocated buffers (struct wpabuf);
39 this does not affect wpa_supplicant usage, but many of the APIs
40 changed and various interfaces (e.g., EAP) is not compatible with old
42 * added support for protecting EAP-AKA/Identity messages with
43 AT_CHECKCODE (optional feature in RFC 4187)
44 * added support for protected result indication with AT_RESULT_IND for
45 EAP-SIM and EAP-AKA (phase1="result_ind=1")
46 * added driver_wext workaround for race condition between scanning and
47 association with drivers that take very long time to scan all
48 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
49 using a longer hardcoded timeout for the scan if the driver supports
50 notifications for scan completion (SIOCGIWSCAN event); this helps,
51 e.g., in cases where wpa_supplicant and madwifi driver ended up in
52 loop where the driver did not even try to associate
53 * stop EAPOL timer tick when no timers are in use in order to reduce
54 power consumption (no need to wake up the process once per second)
56 * added support for privilege separation (run only minimal part of
57 wpa_supplicant functionality as root and rest as unprivileged,
58 non-root process); see 'Privilege separation' in README for details;
59 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
61 * changed scan results data structure to include all information
62 elements to make it easier to support new IEs; old get_scan_result()
63 driver_ops is still supported for backwards compatibility (results
64 are converted internally to the new format), but all drivers should
65 start using the new get_scan_results2() to make them more likely to
66 work with new features
67 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
68 application, i.e., it does not require Qt3Support anymore; Windows
69 binary of wpa_gui.exe is now from this directory and only requires
70 QtCore4.dll and QtGui4.dll libraries
71 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
72 available as a separate package to make wpa_gui installation easier:
73 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
74 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
75 only shared key/password authentication is supported in this version
78 * added support for configuring password as NtPasswordHash
79 (16-byte MD4 hash of password) in hash:<32 hex digits> format
80 * added support for fallback from abbreviated TLS handshake to
81 full handshake when using EAP-FAST (e.g., due to an expired
83 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
84 draft (draft-ietf-emu-eap-gpsk-07.txt)
85 * added support for drivers that take care of RSN 4-way handshake
86 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
87 WPA_ALG_PMK in set_key)
88 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
89 .config); this version supports only ap_scan=2 mode and allow the
90 driver to take care of the 4-way handshake
91 * fixed a buffer overflow in parsing TSF from scan results when using
92 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
94 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
95 * fixed an integer overflow issue in the ASN.1 parser used by the
96 (experimental) internal TLS implementation to avoid a potential
98 * fixed a race condition with -W option (wait for a control interface
99 monitor before starting) that could have caused the first messages to
101 * added support for processing TNCC-TNCS-Messages to report
102 recommendation (allow/none/isolate) when using TNC [Bug 243]
105 * added network configuration parameter 'frequency' for setting
106 initial channel for IBSS (adhoc) networks
107 * added experimental IEEE 802.11r/D6.0 support
108 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
109 * updated EAP-PSK to use the IANA-allocated EAP type 47
110 * fixed EAP-PAX key derivation
111 * fixed EAP-PSK bit ordering of the Flags field
112 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
113 tunnelled identity request (previously, the identifier from the outer
114 method was used, not the tunnelled identifier which could be
116 * added support for fragmentation of outer TLS packets during Phase 2
117 of EAP-PEAP/TTLS/FAST
118 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
119 * added support for EAP-FAST authentication with inner methods that
120 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
121 for PAC provisioning)
122 * added support for authenticated EAP-FAST provisioning
123 * added support for configuring maximum number of EAP-FAST PACs to
124 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
125 * added support for storing EAP-FAST PACs in binary format
126 (fast_pac_format=binary in phase1 string)
127 * fixed dbus ctrl_iface to validate message interface before
128 dispatching to avoid a possible segfault [Bug 190]
129 * fixed PeerKey key derivation to use the correct PRF label
130 * updated Windows binary build to link against OpenSSL 0.9.8d and
131 added support for EAP-FAST
132 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
133 draft (draft-ietf-emu-eap-gpsk-04.txt)
134 * fixed EAP-AKA Notification processing to allow Notification to be
135 processed after AKA Challenge response has been sent
136 * updated to use IEEE 802.11w/D2.0 for management frame protection
138 * fixed EAP-TTLS implementation not to crash on use of freed memory
139 if TLS library initialization fails
140 * added support for EAP-TNC (Trusted Network Connect)
141 (this version implements the EAP-TNC method and EAP-TTLS changes
142 needed to run two methods in sequence (IF-T) and the IF-IMC and
143 IF-TNCCS interfaces from TNCC)
146 * added experimental, integrated TLSv1 client implementation with the
147 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
148 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
149 .config); this can be useful, e.g., if the target system does not
150 have a suitable TLS library and a minimal code size is required
151 (total size of this internal TLS/crypto code is bit under 50 kB on
152 x86 and the crypto code is shared by rest of the supplicant so some
153 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
154 * removed STAKey handshake since PeerKey handshake has replaced it in
155 IEEE 802.11ma and there are no known deployments of STAKey
156 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
157 draft (draft-ietf-emu-eap-gpsk-01.txt)
158 * added preliminary implementation of IEEE 802.11w/D1.0 (management
160 (Note: this requires driver support to work properly.)
161 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
162 * fixed Windows named pipes ctrl_iface to not stop listening for
163 commands if client program opens a named pipe and closes it
164 immediately without sending a command
165 * fixed USIM PIN status determination for the case that PIN is not
166 needed (this allows EAP-AKA to be used with USIM cards that do not
168 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
169 be used with cards that do not support file selection based on
171 * added support for matching the subjectAltName of the authentication
172 server certificate against multiple name components (e.g.,
173 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
174 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
175 affects IEEE 802.1X with dynamic WEP keys)
176 * changed ctrl_iface network configuration 'get' operations to not
177 return password/key material; if these fields are requested, "*"
178 will be returned if the password/key is set, but the value of the
179 parameter is not exposed
182 * added support for building Windows version with UNICODE defined
183 (wide-char functions)
184 * driver_ndis: fixed static WEP configuration to avoid race condition
185 issues with some NDIS drivers between association and setting WEP
187 * driver_ndis: added validation for IELength value in scan results to
188 avoid crashes when using buggy NDIS drivers [Bug 165]
189 * fixed Release|Win32 target in the Visual Studio project files
190 (previously, only Debug|Win32 target was set properly)
191 * changed control interface API call wpa_ctrl_pending() to allow it to
192 return -1 on error (e.g., connection lost); control interface clients
193 will need to make sure that they verify that the value is indeed >0
194 when determining whether there are pending messages
195 * added an alternative control interface backend for Windows targets:
196 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
197 control interface mechanism for Windows builds (previously, UDP to
199 * changed ctrl_interface configuration for UNIX domain sockets:
200 - deprecated ctrl_interface_group variable (it may be removed in
202 - allow both directory and group be configured with ctrl_interface
203 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
204 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
205 case when group is not changed
206 * added support for controlling more than one interface per process in
208 * added a workaround for a case where the AP is using unknown address
209 (e.g., MAC address of the wired interface) as the source address for
210 EAPOL-Key frames; previously, that source address was used as the
211 destination for EAPOL-Key frames and in key derivation; now, BSSID is
212 used even if the source address does not match with it
213 (this resolves an interoperability issue with Thomson SpeedTouch 580)
214 * added a workaround for UDP-based control interface (which was used in
215 Windows builds before this release) to prevent packets with forged
216 addresses from being accepted as local control requests
217 * removed ndis_events.cpp and possibility of using external
218 ndis_events.exe; C version (ndis_events.c) is fully functional and
219 there is no desire to maintain two separate versions of this
221 * ndis_events: Changed NDIS event notification design to use WMI to
222 learn the adapter description through Win32_PnPEntity class; this
223 should fix some cases where the adapter name was not recognized
224 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
226 * fixed selection of the first network in ap_scan=2 mode; previously,
227 wpa_supplicant could get stuck in SCANNING state when only the first
228 network for enabled (e.g., after 'wpa_cli select_network 0')
229 * winsvc: added support for configuring ctrl_interface parameters in
230 registry (ctrl_interface string value in
231 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
232 required to enable control interface (previously, this was hardcoded
234 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
235 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
238 * fixed build with CONFIG_STAKEY=y [Bug 143]
239 * added support for doing MLME (IEEE 802.11 management frame
240 processing) in wpa_supplicant when using Devicescape IEEE 802.11
241 stack (wireless-dev.git tree)
242 * added a new network block configuration option, fragment_size, to
243 configure the maximum EAP fragment size
244 * driver_ndis: Disable WZC automatically for the selected interface to
245 avoid conflicts with two programs trying to control the radio; WZC
246 will be re-enabled (if it was enabled originally) when wpa_supplicant
248 * added an experimental TLSv1 client implementation
249 (CONFIG_TLS=internal) that can be used instead of an external TLS
250 library, e.g., to reduce total size requirement on systems that do
251 not include any TLS library by default (this is not yet complete;
252 basic functionality is there, but certificate validation is not yet
254 * added PeerKey handshake implementation for IEEE 802.11e
255 direct link setup (DLS) to replace STAKey handshake
256 * fixed WPA PSK update through ctrl_iface for the case where the old
257 PSK was derived from an ASCII passphrase and the new PSK is set as
258 a raw PSK (hex string)
259 * added new configuration option for identifying which network block
260 was used (id_str in wpa_supplicant.conf; included on
261 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
262 variable in wpa_cli action scripts; in addition WPA_ID variable is
263 set to the current unique identifier that wpa_supplicant assigned
264 automatically for the network and that can be used with
265 GET_NETWORK/SET_NETWORK ctrl_iface commands)
266 * wpa_cli action script is now called only when the connect/disconnect
267 status changes or when associating with a different network
268 * fixed configuration parser not to remove CCMP from group cipher list
269 if WPA-None (adhoc) is used (pairwise=NONE in that case)
270 * fixed integrated NDIS events processing not to hang the process due
271 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
272 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
273 draft-clancy-emu-eap-shared-secret-00.txt)
274 * added Microsoft Visual Studio 2005 solution and project files for
275 build wpa_supplicant for Windows (see vs2005 subdirectory)
276 * eloop_win: fixed unregistration of Windows events
277 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
278 at the end of RSN pre-authentication and added unregistration of
279 a Windows event to avoid getting eloop_win stuck with an invalid
281 * driver_ndis: added support for selecting AP based on BSSID
282 * added new environmental variable for wpa_cli action scripts:
283 WPA_CTRL_DIR is the current control interface directory
284 * driver_ndis: added support for using NDISUIO instead of WinPcap for
285 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
286 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
287 wpa_supplicant without requiring WinPcap; note that using NDISUIO
288 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
289 only one application to open the device
290 * changed NDIS driver naming to only include device GUID, e.g.,
291 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
292 specific \Device\NPF_ prefix before the GUID; the prefix is still
293 allowed for backwards compatibility, but it is not required anymore
294 when specifying the interface
295 * driver_ndis: re-initialize driver interface is the adapter is removed
296 and re-inserted [Bug 159]
297 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
298 big endian hosts [Bug 146]
301 * fixed EAP-GTC response to include correct user identity when run as
302 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
303 * driver_ndis: Fixed encryption mode configuration for unencrypted
304 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
305 refused to associate with open networks) [Bug 106]
306 * driver_ndis: use BSSID OID polling to detect when IBSS network is
307 formed even when ndis_events code is included since some NDIS drivers
308 do not generate media connect events in IBSS mode
309 * config_winreg: allow global ctrl_interface parameter to be configured
311 * config_winreg: added support for saving configuration data into
313 * added support for controlling network device operational state
314 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
315 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
316 that can use this information)
317 * driver_wext: added support for WE-21 change to SSID configuration
318 * driver_wext: fixed privacy configuration for static WEP keys mode
320 * added an optional driver_ops callback for MLME-SETPROTECTION.request
322 * added support for EAP-SAKE (no EAP method number allocated yet, so
323 this is using the same experimental type 255 as EAP-PSK)
324 * added support for dynamically loading EAP methods (.so files) instead
325 of requiring them to be statically linked in; this is disabled by
326 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
330 * do not try to use USIM APDUs when initializing PC/SC for SIM card
331 access for a network that has not enabled EAP-AKA
332 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
333 v0.5.1 due to the new support for expanded EAP types)
334 * added support for generating EAP Expanded Nak
335 * try to fetch scan results once before requesting new scan when
336 starting up in ap_scan=1 mode (this can speed up initial association
337 a lot with, e.g., madwifi-ng driver)
338 * added support for receiving EAPOL frames from a Linux bridge
339 interface (-bbr0 on command line)
340 * fixed EAPOL re-authentication for sessions that used PMKSA caching
341 * changed EAP method registration to use a dynamic list of methods
342 instead of a static list generated at build time
343 * fixed PMKSA cache deinitialization not to use freed memory when
344 removing PMKSA entries
345 * fixed a memory leak in EAP-TTLS re-authentication
346 * reject WPA/WPA2 message 3/4 if it does not include any valid
348 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
349 if the driver does not support SIOCSIWAUTH
352 * driver_test: added better support for multiple APs and STAs by using
353 a directory with sockets that include MAC address for each device in
354 the name (driver_param=test_dir=/tmp/test)
355 * added support for EAP expanded type (vendor specific EAP methods)
356 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
357 option can be changed if needed
358 * wpa_cli/wpa_gui: skip non-socket files in control directory when
359 using UNIX domain sockets; this avoids selecting an incorrect
360 interface (e.g., a PID file could be in this directory, even though
361 use of this directory for something else than socket files is not
363 * fixed TLS library deinitialization after RSN pre-authentication not
364 to disable TLS library for normal authentication
365 * driver_wext: Remove null-termination from SSID length if the driver
366 used it; some Linux drivers do this and they were causing problems in
367 wpa_supplicant not finding matching configuration block. This change
368 would break a case where the SSID actually ends in '\0', but that is
369 not likely to happen in real use.
370 * fixed PMKSA cache processing not to trigger deauthentication if the
371 current PMKSA cache entry is replaced with a valid new entry
372 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
373 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
376 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
377 * added experimental STAKey handshake implementation for IEEE 802.11e
378 direct link setup (DLS); note: this is disabled by default in both
379 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
381 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
382 decrypt AT_ENCR_DATA attributes correctly
383 * fixed EAP-AKA to allow resynchronization within the same session
384 * made code closer to ANSI C89 standard to make it easier to port to
385 other C libraries and compilers
386 * started moving operating system or C library specific functions into
387 wrapper functions defined in os.h and implemented in os_*.c to make
389 * wpa_supplicant can now be built with Microsoft Visual C++
390 (e.g., with the freely available Toolkit 2003 version or Visual
391 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
392 example makefile for nmake
393 * added support for using Windows registry for command line parameters
394 (CONFIG_MAIN=main_winsvc) and configuration data
395 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
396 contents; this version can be run both as a Windows service and as a
397 normal application; 'wpasvc.exe app' to start as applicant,
398 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
399 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
401 * made it possible to link ndis_events.exe functionality into
402 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
403 * added better support for multiple control interface backends
404 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
405 * fixed PC/SC code to use correct length for GSM AUTH command buffer
406 and to not use pioRecvPci with SCardTransmit() calls; these were not
407 causing visible problems with pcsc-lite, but Windows Winscard.dll
408 refused the previously used parameters; this fixes EAP-SIM and
409 EAP-AKA authentication using SIM/USIM card under Windows
410 * added new event loop implementation for Windows using
411 WaitForMultipleObject() instead of select() in order to allow waiting
412 for non-socket objects; this can be selected with
413 CONFIG_ELOOP=eloop_win in .config
414 * added support for selecting l2_packet implementation in .config
415 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
416 winpcap, freebsd, none)
417 * added new l2_packet implementation for WinPcap
418 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
419 reduce latency in EAPOL receive processing from about 100 ms to about
421 * added support for EAP-FAST key derivation using other ciphers than
422 RC4-128-SHA for authentication and AES128-SHA for provisioning
423 * added support for configuring CA certificate as DER file and as a
425 * fixed private key configuration as configuration blob and added
426 support for using PKCS#12 as a blob
427 * tls_gnutls: added support for using PKCS#12 files; added support for
429 * added support for loading trusted CA certificates from Windows
430 certificate store: ca_cert="cert_store://<name>", where <name> is
431 likely CA (Intermediate CA certificates) or ROOT (root certificates)
432 * added C version of ndis_events.cpp and made it possible to build this
433 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
434 easily on cross-compilation builds
435 * added wpasvc.exe into Windows binary release; this is an alternative
436 version of wpa_supplicant.exe with configuration backend using
437 Windows registry and with the entry point designed to run as a
439 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
440 wpasvc.exe and removed this additional tool from the Windows binary
441 release since it is not needed anymore
442 * load winscard.dll functions dynamically when building with MinGW
443 since MinGW does not yet include winscard library
445 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
446 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
447 and WinPcap to receive frames sent to PAE group address
448 * disable EAP state machine when IEEE 802.1X authentication is not used
449 in order to get rid of bogus "EAP failed" messages
450 * fixed OpenSSL error reporting to go through all pending errors to
451 avoid confusing reports of old errors being reported at later point
453 * fixed configuration file updating to not write empty variables
454 (e.g., proto or key_mgmt) that the file parser would not accept
455 * fixed ADD_NETWORK ctrl_iface command to use the same default values
456 for variables as empty network definitions read from config file
458 * fixed EAP state machine to not discard EAP-Failure messages in many
459 cases (e.g., during TLS handshake)
460 * fixed a infinite loop in private key reading if the configured file
461 cannot be parsed successfully
462 * driver_madwifi: added support for madwifi-ng
463 * wpa_gui: do not display password/PSK field contents
464 * wpa_gui: added CA certificate configuration
465 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
466 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
467 the new AP is using different WPA/RSN IE
468 * use longer timeout for IEEE 802.11 association to avoid problems with
469 drivers that may take more than five second to associate
472 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
473 RSN IE, but WPA IE would match with wpa_supplicant configuration
474 * added support for named configuration blobs in order to avoid having
475 to use file system for external files (e.g., certificates);
476 variables can be set to "blob://<blob name>" instead of file path to
477 use a named blob; supported fields: pac_file, client_cert,
479 * fixed RSN pre-authentication (it was broken in the clean up of WPA
480 state machine interface in v0.4.5)
481 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
482 sure the driver configures broadcast decryption correctly
483 * added ca_path (and ca_path2) configuration variables that can be used
484 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
485 system-wide trusted CA list
486 * added support for starting wpa_supplicant without a configuration
487 file (-C argument must be used to set ctrl_interface parameter for
488 this case; in addition, -p argument can be used to provide
489 driver_param; these new arguments can also be used with a
490 configuration to override the values from the configuration)
491 * added global control interface that can be optionally used for adding
492 and removing network interfaces dynamically (-g command line argument
493 for both wpa_supplicant and wpa_cli) without having to restart
494 wpa_supplicant process
496 - try to save configuration whenever something is modified
497 - added WEP key configuration
498 - added possibility to edit the current network configuration
499 * driver_ndis: fixed driver polling not to increase frequency on each
500 received EAPOL frame due to incorrectly cancelled timeout
501 * added simple configuration file examples (in examples subdirectory)
502 * fixed driver_wext.c to filter wireless events based on ifindex to
503 avoid interfaces receiving events from other interfaces
504 * delay sending initial EAPOL-Start couple of seconds to speed up
505 authentication for the most common case of Authenticator starting
506 EAP authentication immediately after association
509 * added a workaround for clearing keys with ndiswrapper to allow
510 roaming from WPA enabled AP to plaintext one
511 * added docbook documentation (doc/docbook) that can be used to
512 generate, e.g., man pages
513 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
514 PF_PACKET in order to prepare for network devices that do not use
515 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
516 * use receipt of EAPOL-Key frame as a lower layer success indication
517 for EAP state machine to allow recovery from dropped EAP-Success
519 * cleaned up internal EAPOL frame processing by not including link
520 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
521 header is added only when transmitted the frame; this makes it easier
522 to use wpa_supplicant on link layers that use different header than
524 * updated EAP-PSK to use draft 9 by default since this can now be
525 tested with hostapd; removed support for draft 3, including
526 server_nai configuration option from network blocks
527 * driver_wired: add PAE address to the multicast address list in order
528 to be able to receive EAPOL frames with drivers that do not include
529 these multicast addresses by default
530 * driver_wext: add support for WE-19
531 * added support for multiple configuration backends (CONFIG_BACKEND
532 option); currently, only 'file' is supported (i.e., the format used
533 in wpa_supplicant.conf)
534 * added support for updating configuration ('wpa_cli save_config');
535 this is disabled by default and can be enabled with global
536 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
537 and wpa_gui to store the configuration changes in a permanent store
538 * added GET_NETWORK ctrl_iface command
539 (e.g., 'wpa_cli get_network 0 ssid')
542 * replaced OpenSSL patch for EAP-FAST support
543 (openssl-tls-extensions.patch) with a more generic and correct
544 patch (the new patch is not compatible with the previous one, so the
545 OpenSSL library will need to be patched with the new patch in order
546 to be able to build wpa_supplicant with EAP-FAST support)
547 * added support for using Windows certificate store (through CryptoAPI)
548 for client certificate and private key operations (EAP-TLS)
549 (see wpa_supplicant.conf for more information on how to configure
550 this with private_key)
551 * ported wpa_gui to Windows
552 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
553 built with the open source version of the Qt4 for Windows
554 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
555 with drivers that do not support WPA
556 * ndis_events: fixed Windows 2000 support
557 * added support for enabling/disabling networks from the list of all
558 configured networks ('wpa_cli enable_network <network id>' and
559 'wpa_cli disable_network <network id>')
560 * added support for adding and removing network from the current
561 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
562 <network id>'); added networks are disabled by default and they can
563 be enabled with enable_network command once the configuration is done
564 for the new network; note: configuration file is not yet updated, so
565 these new networks are lost when wpa_supplicant is restarted
566 * added support for setting network configuration parameters through
567 the control interface, for example:
568 wpa_cli set_network 0 ssid "\"my network\""
569 * fixed parsing of strings that include both " and # within double
570 quoted area (e.g., "start"#end")
571 * added EAP workaround for PEAP session resumption: allow outer,
572 i.e., not tunneled, EAP-Success to terminate session since; this can
573 be disabled with eap_workaround=0
574 (this was allowed for PEAPv1 before, but now it is also allowed for
575 PEAPv0 since at least one RADIUS authentication server seems to be
576 doing this for PEAPv0, too)
577 * wpa_gui: added preliminary support for adding new networks to the
578 wpa_supplicant configuration (double click on the scan results to
579 open network configuration)
582 * removed interface for external EAPOL/EAP supplicant (e.g.,
583 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
584 anymore and is unlikely to be used by anyone
585 * driver_ndis: fixed WinPcap 3.0 support
586 * fixed build with CONFIG_DNET_PCAP=y on Linux
587 * l2_packet: moved different implementations into separate files
591 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
592 (note: ipw2100-1.1.0 is likely to require an update to work with
594 * added support for using ap_scan=2 mode with multiple network blocks;
595 wpa_supplicant will go through the networks one by one until the
596 driver reports a successful association; this uses the same order for
597 networks as scan_ssid=1 scans, i.e., the priority field is ignored
598 and the network block order in the file is used instead
599 * fixed a potential issue in RSN pre-authentication ending up using
600 freed memory if pre-authentication times out
601 * added support for matching alternative subject name extensions of the
602 authentication server certificate; new configuration variables
603 altsubject_match and altsubject_match2
604 * driver_ndis: added support for IEEE 802.1X authentication with wired
606 * added support for querying private key password (EAP-TLS) through the
607 control interface (wpa_cli/wpa_gui) if one is not included in the
609 * driver_broadcom: fixed couple of memory leaks in scan result
611 * EAP-PAX is now registered as EAP type 46
612 * fixed EAP-PAX MAC calculation
613 * fixed EAP-PAX CK and ICK key derivation
614 * added support for using password with EAP-PAX (as an alternative to
615 entering key with eappsk); SHA-1 hash of the password will be used as
617 * added support for arbitrary driver interface parameters through the
618 configuration file with a new driver_param field; this adds a new
619 driver_ops function set_param()
620 * added possibility to override l2_packet module with driver interface
621 API (new send_eapol handler); this can be used to implement driver
622 specific TX/RX functions for EAPOL frames
623 * fixed ctrl_interface_group processing for the case where gid is
624 entered as a number, not group name
625 * driver_test: added support for testing hostapd with wpa_supplicant
626 by using test driver interface without any kernel drivers or network
630 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
631 packets to be encrypted; this was apparently broken by the changed
632 ioctl order in v0.4.0
633 * driver_madwifi: added preliminary support for compiling against 'BSD'
634 branch of madwifi CVS tree
635 * added support for EAP-MSCHAPv2 password retries within the same EAP
636 authentication session
637 * added support for password changes with EAP-MSCHAPv2 (used when the
638 password has expired)
639 * added support for reading additional certificates from PKCS#12 files
640 and adding them to the certificate chain
641 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
643 * fixed a possible double free in EAP-TTLS fast-reauthentication when
644 identity or password is entered through control interface
645 * display EAP Notification messages to user through control interface
646 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
647 * added GUI version of wpa_cli, wpa_gui; this is not build
648 automatically with 'make'; use 'make wpa_gui' to build (this requires
649 Qt development tools)
650 * added 'disconnect' command to control interface for setting
651 wpa_supplicant in state where it will not associate before
652 'reassociate' command has been used
653 * added support for selecting a network from the list of all configured
654 networks ('wpa_cli select_network <network id>'; this disabled all
655 other networks; to re-enable, 'wpa_cli select_network any')
656 * added support for getting scan results through control interface
657 * added EAP workaround for PEAPv1 session resumption: allow outer,
658 i.e., not tunneled, EAP-Success to terminate session since; this can
659 be disabled with eap_workaround=0
661 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
662 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
663 used to reduce the size of the wpa_supplicant considerably if
664 debugging code is not needed
665 * fixed EAPOL-Key validation to drop packets with invalid Key Data
666 Length; such frames could have crashed wpa_supplicant due to buffer
668 * added support for wired authentication (IEEE 802.1X on wired
669 Ethernet); driver interface 'wired'
670 * obsoleted set_wpa() handler in the driver interface API (it can be
671 replaced by moving enable/disable functionality into init()/deinit())
672 (calls to set_wpa() are still present for backwards compatibility,
673 but they may be removed in the future)
674 * driver_madwifi: fixed association in plaintext mode
675 * modified the EAP workaround that accepts EAP-Success with incorrect
676 Identifier to be even less strict about verification in order to
677 interoperate with some authentication servers
678 * added support for sending TLS alerts
679 * added support for 'any' SSID wildcard; if ssid is not configured or
680 is set to an empty string, any SSID will be accepted for non-WPA AP
681 * added support for asking PIN (for SIM) from frontends (e.g.,
682 wpa_cli); if a PIN is needed, but not included in the configuration
683 file, a control interface request is sent and EAP processing is
684 delayed until the PIN is available
685 * added support for using external devices (e.g., a smartcard) for
686 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
687 new wpa_supplicant.conf variables:
688 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
689 - network: engine, engine_id, key_id
690 * added experimental support for EAP-PAX
691 * added monitor mode for wpa_cli (-a<path to a program to run>) that
692 allows external commands (e.g., shell scripts) to be run based on
693 wpa_supplicant events, e.g., when authentication has been completed
694 and data connection is ready; other related wpa_cli arguments:
695 -B (run in background), -P (write PID file); wpa_supplicant has a new
696 command line argument (-W) that can be used to make it wait until a
697 control interface command is received in order to avoid missing
699 * added support for opportunistic WPA2 PMKSA key caching (disabled by
700 default, can be enabled with proactive_key_caching=1)
701 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
702 Authenticator rejects PMKSA caching attempt and the driver is not
703 using assoc_info events
704 * added -P<pid file> argument for wpa_supplicant to write the current
705 process id into a file
707 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
708 * added new phase1 option parameter, include_tls_length=1, to force
709 wpa_supplicant to add TLS Message Length field to all TLS messages
710 even if the packet is not fragmented; this may be needed with some
711 authentication servers
712 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
713 using drivers that take care of AP selection (e.g., when using
715 * fixed reprocessing of pending request after ctrl_iface requests for
716 identity/password/otp
717 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
718 EAP-PEAP and EAP-TTLS
719 * all drivers using driver_wext: set interface up and select Managed
720 mode when starting wpa_supplicant; set interface down when exiting
721 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
722 ipw2100 and ipw2200; please note that this also changed the
723 configuration variable in .config to CONFIG_DRIVER_IPW
726 * fixed a busy loop introduced in v0.3.5 for scan result processing
727 when no matching AP is found
730 * added a workaround for an interoperability issue with a Cisco AP
732 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
733 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
734 retransmission of dropped frames)
735 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
736 (e.g., segfault when processing EAPOL-Key frames)
737 * fixed EAP workaround and fast reauthentication configuration for
738 RSN pre-authentication; previously these were disabled and
739 pre-authentication would fail if the used authentication server
740 requires EAP workarounds
741 * added support for blacklisting APs that fail or timeout
742 authentication in ap_scan=1 mode so that all APs are tried in cases
743 where the ones with strongest signal level are failing authentication
744 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
745 authentication attempt
746 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
747 in the previous authentication (previously, only Phase 1 success was
751 * added preliminary support for IBSS (ad-hoc) mode configuration
752 (mode=1 in network block); this included a new key_mgmt mode
753 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
754 key management; see wpa_supplicant.conf for more details and an
755 example on how to configure this (note: this is currently implemented
756 only for driver_hostapd.c, but the changes should be trivial to add
757 in associate() handler for other drivers, too (assuming the driver
759 * added preliminary port for native Windows (i.e., no cygwin) using
763 * added optional support for GNU Readline and History Libraries for
764 wpa_cli (CONFIG_READLINE)
765 * cleaned up EAP state machine <-> method interface and number of
766 small problems with error case processing not terminating on
767 EAP-Failure but waiting for timeout
768 * added couple of workarounds for interoperability issues with a
769 Cisco AP when using WPA2
770 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
771 Note: This requires a patch for openssl to add support for TLS
772 extensions and number of workarounds for operations without
773 certificates. Proof of concept type of experimental patch is
774 included in openssl-tls-extensions.patch.
777 * fixed private key loading for cases where passphrase is not set
778 * fixed Windows/cygwin L2 packet handler freeing; previous version
779 could cause a segfault when RSN pre-authentication was completed
780 * added support for PMKSA caching with drivers that generate RSN IEs
781 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
782 but similar code can be easily added to driver_ndiswrapper.c once
783 ndiswrapper gets full support for RSN PMKSA caching
784 * improved recovery from PMKID mismatches by requesting full EAP
785 authentication in case of failed PMKSA caching attempt
786 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
787 (this requires that ndis_events is ran while wpa_supplicant is
789 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
790 * added support for driver interfaces to replace the interface name
791 based on driver/OS specific mapping, e.g., in case of driver_ndis,
792 this allows the beginning of the adapter description to be used as
794 * added support for CR+LF (Windows-style) line ends in configuration
796 * driver_ndis: enable radio before starting scanning, disable radio
798 * modified association event handler to set portEnabled = FALSE before
799 clearing port Valid in order to reset EAP state machine and avoid
800 problems with new authentication getting ignored because of state
801 machines ending up in AUTHENTICATED/SUCCESS state based on old
803 * added support for driver events to add PMKID candidates in order to
804 allow drivers to give priority to most likely roaming candidates
805 * driver_hostap: moved PrivacyInvoked configuration to associate()
806 function so that this will not be set for plaintext connections
807 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
808 interface can distinguish plaintext and IEEE 802.1X (no WPA)
810 * fixed static WEP key configuration to use broadcast/default type for
811 all keys (previously, the default TX key was configured as pairwise/
813 * driver_ndis: added legacy WPA capability detection for non-WPA2
815 * added support for setting static WEP keys for IEEE 802.1X without
816 dynamic WEP keying (eapol_flags=0)
819 * added support for reading PKCS#12 (PFX) files (as a replacement for
820 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
821 * fixed compilation with CONFIG_PCSC=y
822 * added new ap_scan mode, ap_scan=2, for drivers that take care of
823 association, but need to be configured with security policy and SSID,
824 e.g., ndiswrapper and NDIS driver; this mode should allow such
825 drivers to work with hidden SSIDs and optimized roaming; when
826 ap_scan=2 is used, only the first network block in the configuration
827 file is used and this configuration should have explicit security
828 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
829 group, proto variables
830 * added experimental port of wpa_supplicant for Windows
831 - driver_ndis.c driver interface (NDIS OIDs)
832 - currently, this requires cygwin and WinPcap
833 - small utility, win_if_list, can be used to get interface name
834 * control interface can now be removed at build time; add
835 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
836 * optional Xsupplicant interface can now be removed at build time;
837 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
838 * added auth_alg to driver interface associate() parameters to make it
839 easier for drivers to configure authentication algorithm as part of
842 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
843 * driver_broadcom: added new driver interface for Broadcom wl.o driver
844 (a generic driver for Broadcom IEEE 802.11a/g cards)
845 * wpa_cli: fixed parsing of -p <path> command line argument
846 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
847 ACK, not tunneled EAP-Success (of which only the first byte was
848 actually send due to a bug in previous code); this seems to
849 interoperate with most RADIUS servers that implements PEAPv1
850 * PEAPv1: added support for terminating PEAP authentication on tunneled
851 EAP-Success message; this can be configured by adding
852 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
853 (some RADIUS servers require this whereas others require a tunneled
855 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
856 the old label for key derivation; previously, the default was 1,
857 but it looks like most existing PEAPv1 implementations use the old
858 label which is thus more suitable default option
859 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
860 * fixed parsing of wep_tx_keyidx
861 * added support for configuring list of allowed Phase 2 EAP types
862 (for both EAP-PEAP and EAP-TTLS) instead of only one type
863 * added support for configuring IEEE 802.11 authentication algorithm
864 (auth_alg; mainly for using Shared Key authentication with static
866 * added support for EAP-AKA (with UMTS SIM)
867 * fixed couple of errors in PCSC handling that could have caused
868 random-looking errors for EAP-SIM
869 * added support for EAP-SIM pseudonyms and fast re-authentication
870 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
872 * added support for EAP-SIM with two challanges
873 (phase1="sim_min_num_chal=3" can be used to require three challenges)
874 * added support for configuring DH/DSA parameters for an ephemeral DH
875 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
876 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
877 and optional DH key exchange to achieve forward secracy with RSA keys
878 * added support for matching subject of the authentication server
879 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
880 configuration variables subject_match and subject_match2
881 * changed SSID configuration in driver_wext.c (used by many driver
882 interfaces) to use ssid_len+1 as the length for SSID since some Linux
884 * fixed couple of unaligned reads in scan result parsing to fix WPA
885 connection on some platforms (e.g., ARM)
886 * added driver interface for Intel ipw2100 driver
887 * added support for LEAP with WPA
888 * added support for larger scan results report (old limit was 4 kB of
889 data, i.e., about 35 or so APs) when using Linux wireless extensions
891 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
892 only if there is a PMKSA cache entry for the current AP
893 * fixed error handling for case where reading of scan results fails:
894 must schedule a new scan or wpa_supplicant will remain waiting
896 * changed debug output to remove shared password/key material by
897 default; all key information can be included with -K command line
898 argument to match the previous behavior
899 * added support for timestamping debug log messages (disabled by
900 default, can be enabled with -t command line argument)
901 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
902 if keys are not configured to be used; this fixes IEEE 802.1X mode
903 with drivers that use this information to configure whether Privacy
904 bit can be in Beacon frames (e.g., ndiswrapper)
905 * avoid clearing driver keys if no keys have been configured since last
906 key clear request; this seems to improve reliability of group key
907 handshake for ndiswrapper & NDIS driver which seems to be suffering
908 of some kind of timing issue when the keys are cleared again after
910 * changed driver interface API:
911 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
912 version is being used (now, this is set to 2; previously, it was
914 - pass pointer to private data structure to all calls
915 - the new API is not backwards compatible; all in-tree driver
916 interfaces has been converted to the new API
917 * added support for controlling multiple interfaces (radios) per
918 wpa_supplicant process; each interface needs to be listed on the
919 command line (-c, -i, -D arguments) with -N as a separator
920 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
921 * added a workaround for EAP servers that incorrectly use same Id for
922 sequential EAP packets
923 * changed libpcap/libdnet configuration to use .config variable,
924 CONFIG_DNET_PCAP, instead of requiring Makefile modification
925 * improved downgrade attack detection in IE verification of msg 3/4:
926 verify both WPA and RSN IEs, if present, not only the selected one;
927 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
928 Probe Response frame, and RSN is enabled in wpa_supplicant
930 * fixed WPA msg 3/4 processing to allow Key Data field contain other
931 IEs than just one WPA IE
932 * added support for FreeBSD and driver interface for the BSD net80211
933 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
934 required kernel mods have not yet been committed
935 * made EAP workarounds configurable; enabled by default, can be
936 disabled with network block option eap_workaround=0
938 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
939 * resolved couple of interoperability issues with EAP-PEAPv1 and
940 Phase 2 (inner EAP) fragment reassembly
941 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
942 AP is using non-zero key index for the unicast key and key index zero
943 for the broadcast key
944 * driver_hostap: fixed IEEE 802.1X WEP key updates and
945 re-authentication by allowing unencrypted EAPOL frames when not using
947 * added a new driver interface, 'wext', which uses only standard,
948 driver independent functionality in Linux wireless extensions;
949 currently, this can be used only for non-WPA IEEE 802.1X mode, but
950 eventually, this is to be extended to support full WPA/WPA2 once
951 Linux wireless extensions get support for this
952 * added support for mode in which the driver is responsible for AP
953 scanning and selection; this is disabled by default and can be
954 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
955 this mode can be used, e.g., with generic 'wext' driver interface to
956 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
957 supporting wireless extensions.
958 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
959 operation with an AP that does not include SSID in the Beacon frames)
960 * added support for new EAP authentication methods:
961 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
962 * added support for asking one-time-passwords from frontends (e.g.,
963 wpa_cli); this 'otp' command works otherwise like 'password' command,
964 but the password is used only once and the frontend will be asked for
965 a new password whenever a request from authenticator requires a
966 password; this can be used with both EAP-OTP and EAP-GTC
967 * changed wpa_cli to automatically re-establish connection so that it
968 does not need to be re-started when wpa_supplicant is terminated and
970 * improved user data (identity/password/otp) requests through
971 frontends: process pending EAPOL packets after getting new
972 information so that full authentication does not need to be
973 restarted; in addition, send pending requests again whenever a new
975 * changed control frontends to use a new directory for socket files to
976 make it easier for wpa_cli to automatically select between interfaces
977 and to provide access control for the control interface;
978 wpa_supplicant.conf: ctrl_interface is now a path
979 (/var/run/wpa_supplicant is the recommended path) and
980 ctrl_interface_group can be used to select which group gets access to
981 the control interface;
982 wpa_cli: by default, try to connect to the first interface available
983 in /var/run/wpa_supplicant; this path can be overriden with -p option
984 and an interface can be selected with -i option (i.e., in most common
985 cases, wpa_cli does not need to get any arguments)
986 * added support for LEAP
987 * added driver interface for Linux ndiswrapper
988 * added priority option for network blocks in the configuration file;
989 this allows networks to be grouped based on priority (the scan
990 results are searched for matches with network blocks in this order)
993 * sort scan results to improve AP selection
994 * fixed control interface socket removal for some error cases
995 * improved scan requesting and authentication timeout
996 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
998 * PEAP version can now be forced with phase1="peapver=<ver>"
999 (mostly for testing; by default, the highest version supported by
1000 both the Supplicant and Authentication Server is selected
1002 * added support for madwifi driver (Atheros ar521x)
1003 * added a workaround for cases where AP sets Install Tx/Rx bit for
1004 WPA Group Key messages when pairwise keys are used (without this,
1005 the Group Key would be used for Tx and the AP would drop frames
1007 * added GSM SIM/USIM interface for GSM authentication algorithm for
1008 EAP-SIM; this requires pcsc-lite
1009 * added support for ATMEL AT76C5XXx driver
1010 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1011 does not include key data in the EAPOL-Key frame (i.e., part of
1012 EAP keying material is used as data encryption key)
1013 * added support for using plaintext and static WEP networks
1017 * added support for new EAP authentication methods:
1018 EAP-TTLS/EAP-MD5-Challenge
1020 EAP-TTLS/EAP-MSCHAPv2
1028 EAP-PEAP/MD5-Challenge
1030 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1031 * added support for anonymous identity (to be used when identity is
1032 sent in plaintext; real identity will be used within TLS protected
1033 tunnel (e.g., with EAP-TTLS)
1034 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1035 * added support for requesting identity and password information using
1036 control interface; in other words, the password for EAP-PEAP or
1037 EAP-TTLS does not need to be included in the configuration file since
1038 a frontand (e.g., wpa_cli) can ask it from the user
1039 * improved RSN pre-authentication to use a candidate list and process
1040 all candidates from each scan; not only one per scan
1041 * fixed RSN IE and WPA IE capabilities field parsing
1042 * ignore Tx bit in GTK IE when Pairwise keys are used
1043 * avoid making new scan requests during IEEE 802.1X negotiation
1044 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1045 with TLS support (this replaces the included implementation with
1046 library code to save about 8 kB since the library code is needed
1048 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1049 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1052 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1054 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1055 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1056 - EAP-MD5 (cannot be used with WPA-RADIUS)
1057 [draft-ietf-eap-rfc2284bis-09.txt]
1058 - EAP-TLS [RFC 2716]
1059 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1060 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1061 [draft-kamath-pppext-eap-mschapv2-00.txt]
1062 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1063 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1064 - new configuration file options: eap, identity, password, ca_cert,
1065 client_cert, privatekey, private_key_passwd
1066 - Xsupplicant is not required anymore, but it can be used by
1067 disabling the internal IEEE 802.1X Supplicant with -e command line
1069 - this code is not included in the default build; Makefile need to
1070 be edited for this (uncomment lines for selected functionality)
1071 - EAP-TLS and EAP-PEAP require openssl libraries
1072 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1073 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1074 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1075 EAPOL-Key frames instead of WPA key handshakes)
1076 * added support for IEEE 802.11i/RSN (WPA2)
1077 - improved PTK Key Handshake
1078 - PMKSA caching, pre-authentication
1079 * fixed wpa_supplicant to ignore possible extra data after WPA
1080 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1081 TPTK' error from message 3 of 4-Way Handshake in case the AP
1082 includes extra data after the EAPOL-Key)
1083 * added interface for external programs (frontends) to control
1085 - CLI example (wpa_cli) with interactive mode and command line
1087 - replaced SIGUSR1 status/statistics with the new control interface
1088 * made some feature compile time configurable
1089 - .config file for make
1090 - driver interfaces (hostap, hermes, ..)
1091 - EAPOL/EAP functions
1094 * Initial version of wpa_supplicant
