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
7 * added support for optional cryptobinding with PEAPv0
8 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
9 allow fallback to full handshake if server rejects PAC-Opaque
12 * removed 'nai' and 'eappsk' network configuration variables that were
13 previously used for configuring user identity and key for EAP-PSK,
14 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
15 replacement for 'nai' (if old configuration used a separate
16 'identity' value, that would now be configured as
17 'anonymous_identity'). 'password' field is now used as the
18 replacement for 'eappsk' (it can also be set using hexstring to
19 present random binary data)
20 * removed '-w' command line parameter (wait for interface to be added,
21 if needed); cleaner way of handling this functionality is to use an
22 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
23 when an interface is added
24 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
25 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
26 indicating when new scan results become available
27 * added new ctrl_iface command, BSS, to allow scan results to be
28 fetched without hitting the message size limits (this command
29 can be used to iterate through the scan results one BSS at the time)
30 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
31 attributes in EAP-SIM Start/Response when using fast reauthentication
32 * fixed EAPOL not to end up in infinite loop when processing dynamic
33 WEP keys with IEEE 802.1X
34 * fixed problems in getting NDIS events from WMI on Windows 2000
37 * added support for Makefile builds to include debug-log-to-a-file
38 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
39 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
40 lengths properly to avoid potential crash caused by invalid messages
41 * added data structure for storing allocated buffers (struct wpabuf);
42 this does not affect wpa_supplicant usage, but many of the APIs
43 changed and various interfaces (e.g., EAP) is not compatible with old
45 * added support for protecting EAP-AKA/Identity messages with
46 AT_CHECKCODE (optional feature in RFC 4187)
47 * added support for protected result indication with AT_RESULT_IND for
48 EAP-SIM and EAP-AKA (phase1="result_ind=1")
49 * added driver_wext workaround for race condition between scanning and
50 association with drivers that take very long time to scan all
51 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
52 using a longer hardcoded timeout for the scan if the driver supports
53 notifications for scan completion (SIOCGIWSCAN event); this helps,
54 e.g., in cases where wpa_supplicant and madwifi driver ended up in
55 loop where the driver did not even try to associate
56 * stop EAPOL timer tick when no timers are in use in order to reduce
57 power consumption (no need to wake up the process once per second)
59 * added support for privilege separation (run only minimal part of
60 wpa_supplicant functionality as root and rest as unprivileged,
61 non-root process); see 'Privilege separation' in README for details;
62 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
64 * changed scan results data structure to include all information
65 elements to make it easier to support new IEs; old get_scan_result()
66 driver_ops is still supported for backwards compatibility (results
67 are converted internally to the new format), but all drivers should
68 start using the new get_scan_results2() to make them more likely to
69 work with new features
70 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
71 application, i.e., it does not require Qt3Support anymore; Windows
72 binary of wpa_gui.exe is now from this directory and only requires
73 QtCore4.dll and QtGui4.dll libraries
74 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
75 available as a separate package to make wpa_gui installation easier:
76 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
77 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
78 only shared key/password authentication is supported in this version
81 * added support for configuring password as NtPasswordHash
82 (16-byte MD4 hash of password) in hash:<32 hex digits> format
83 * added support for fallback from abbreviated TLS handshake to
84 full handshake when using EAP-FAST (e.g., due to an expired
86 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
87 draft (draft-ietf-emu-eap-gpsk-07.txt)
88 * added support for drivers that take care of RSN 4-way handshake
89 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
90 WPA_ALG_PMK in set_key)
91 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
92 .config); this version supports only ap_scan=2 mode and allow the
93 driver to take care of the 4-way handshake
94 * fixed a buffer overflow in parsing TSF from scan results when using
95 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
97 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
98 * fixed an integer overflow issue in the ASN.1 parser used by the
99 (experimental) internal TLS implementation to avoid a potential
101 * fixed a race condition with -W option (wait for a control interface
102 monitor before starting) that could have caused the first messages to
104 * added support for processing TNCC-TNCS-Messages to report
105 recommendation (allow/none/isolate) when using TNC [Bug 243]
108 * added network configuration parameter 'frequency' for setting
109 initial channel for IBSS (adhoc) networks
110 * added experimental IEEE 802.11r/D6.0 support
111 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
112 * updated EAP-PSK to use the IANA-allocated EAP type 47
113 * fixed EAP-PAX key derivation
114 * fixed EAP-PSK bit ordering of the Flags field
115 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
116 tunnelled identity request (previously, the identifier from the outer
117 method was used, not the tunnelled identifier which could be
119 * added support for fragmentation of outer TLS packets during Phase 2
120 of EAP-PEAP/TTLS/FAST
121 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
122 * added support for EAP-FAST authentication with inner methods that
123 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
124 for PAC provisioning)
125 * added support for authenticated EAP-FAST provisioning
126 * added support for configuring maximum number of EAP-FAST PACs to
127 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
128 * added support for storing EAP-FAST PACs in binary format
129 (fast_pac_format=binary in phase1 string)
130 * fixed dbus ctrl_iface to validate message interface before
131 dispatching to avoid a possible segfault [Bug 190]
132 * fixed PeerKey key derivation to use the correct PRF label
133 * updated Windows binary build to link against OpenSSL 0.9.8d and
134 added support for EAP-FAST
135 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
136 draft (draft-ietf-emu-eap-gpsk-04.txt)
137 * fixed EAP-AKA Notification processing to allow Notification to be
138 processed after AKA Challenge response has been sent
139 * updated to use IEEE 802.11w/D2.0 for management frame protection
141 * fixed EAP-TTLS implementation not to crash on use of freed memory
142 if TLS library initialization fails
143 * added support for EAP-TNC (Trusted Network Connect)
144 (this version implements the EAP-TNC method and EAP-TTLS changes
145 needed to run two methods in sequence (IF-T) and the IF-IMC and
146 IF-TNCCS interfaces from TNCC)
149 * added experimental, integrated TLSv1 client implementation with the
150 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
151 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
152 .config); this can be useful, e.g., if the target system does not
153 have a suitable TLS library and a minimal code size is required
154 (total size of this internal TLS/crypto code is bit under 50 kB on
155 x86 and the crypto code is shared by rest of the supplicant so some
156 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
157 * removed STAKey handshake since PeerKey handshake has replaced it in
158 IEEE 802.11ma and there are no known deployments of STAKey
159 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
160 draft (draft-ietf-emu-eap-gpsk-01.txt)
161 * added preliminary implementation of IEEE 802.11w/D1.0 (management
163 (Note: this requires driver support to work properly.)
164 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
165 * fixed Windows named pipes ctrl_iface to not stop listening for
166 commands if client program opens a named pipe and closes it
167 immediately without sending a command
168 * fixed USIM PIN status determination for the case that PIN is not
169 needed (this allows EAP-AKA to be used with USIM cards that do not
171 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
172 be used with cards that do not support file selection based on
174 * added support for matching the subjectAltName of the authentication
175 server certificate against multiple name components (e.g.,
176 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
177 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
178 affects IEEE 802.1X with dynamic WEP keys)
179 * changed ctrl_iface network configuration 'get' operations to not
180 return password/key material; if these fields are requested, "*"
181 will be returned if the password/key is set, but the value of the
182 parameter is not exposed
185 * added support for building Windows version with UNICODE defined
186 (wide-char functions)
187 * driver_ndis: fixed static WEP configuration to avoid race condition
188 issues with some NDIS drivers between association and setting WEP
190 * driver_ndis: added validation for IELength value in scan results to
191 avoid crashes when using buggy NDIS drivers [Bug 165]
192 * fixed Release|Win32 target in the Visual Studio project files
193 (previously, only Debug|Win32 target was set properly)
194 * changed control interface API call wpa_ctrl_pending() to allow it to
195 return -1 on error (e.g., connection lost); control interface clients
196 will need to make sure that they verify that the value is indeed >0
197 when determining whether there are pending messages
198 * added an alternative control interface backend for Windows targets:
199 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
200 control interface mechanism for Windows builds (previously, UDP to
202 * changed ctrl_interface configuration for UNIX domain sockets:
203 - deprecated ctrl_interface_group variable (it may be removed in
205 - allow both directory and group be configured with ctrl_interface
206 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
207 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
208 case when group is not changed
209 * added support for controlling more than one interface per process in
211 * added a workaround for a case where the AP is using unknown address
212 (e.g., MAC address of the wired interface) as the source address for
213 EAPOL-Key frames; previously, that source address was used as the
214 destination for EAPOL-Key frames and in key derivation; now, BSSID is
215 used even if the source address does not match with it
216 (this resolves an interoperability issue with Thomson SpeedTouch 580)
217 * added a workaround for UDP-based control interface (which was used in
218 Windows builds before this release) to prevent packets with forged
219 addresses from being accepted as local control requests
220 * removed ndis_events.cpp and possibility of using external
221 ndis_events.exe; C version (ndis_events.c) is fully functional and
222 there is no desire to maintain two separate versions of this
224 * ndis_events: Changed NDIS event notification design to use WMI to
225 learn the adapter description through Win32_PnPEntity class; this
226 should fix some cases where the adapter name was not recognized
227 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
229 * fixed selection of the first network in ap_scan=2 mode; previously,
230 wpa_supplicant could get stuck in SCANNING state when only the first
231 network for enabled (e.g., after 'wpa_cli select_network 0')
232 * winsvc: added support for configuring ctrl_interface parameters in
233 registry (ctrl_interface string value in
234 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
235 required to enable control interface (previously, this was hardcoded
237 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
238 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
241 * fixed build with CONFIG_STAKEY=y [Bug 143]
242 * added support for doing MLME (IEEE 802.11 management frame
243 processing) in wpa_supplicant when using Devicescape IEEE 802.11
244 stack (wireless-dev.git tree)
245 * added a new network block configuration option, fragment_size, to
246 configure the maximum EAP fragment size
247 * driver_ndis: Disable WZC automatically for the selected interface to
248 avoid conflicts with two programs trying to control the radio; WZC
249 will be re-enabled (if it was enabled originally) when wpa_supplicant
251 * added an experimental TLSv1 client implementation
252 (CONFIG_TLS=internal) that can be used instead of an external TLS
253 library, e.g., to reduce total size requirement on systems that do
254 not include any TLS library by default (this is not yet complete;
255 basic functionality is there, but certificate validation is not yet
257 * added PeerKey handshake implementation for IEEE 802.11e
258 direct link setup (DLS) to replace STAKey handshake
259 * fixed WPA PSK update through ctrl_iface for the case where the old
260 PSK was derived from an ASCII passphrase and the new PSK is set as
261 a raw PSK (hex string)
262 * added new configuration option for identifying which network block
263 was used (id_str in wpa_supplicant.conf; included on
264 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
265 variable in wpa_cli action scripts; in addition WPA_ID variable is
266 set to the current unique identifier that wpa_supplicant assigned
267 automatically for the network and that can be used with
268 GET_NETWORK/SET_NETWORK ctrl_iface commands)
269 * wpa_cli action script is now called only when the connect/disconnect
270 status changes or when associating with a different network
271 * fixed configuration parser not to remove CCMP from group cipher list
272 if WPA-None (adhoc) is used (pairwise=NONE in that case)
273 * fixed integrated NDIS events processing not to hang the process due
274 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
275 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
276 draft-clancy-emu-eap-shared-secret-00.txt)
277 * added Microsoft Visual Studio 2005 solution and project files for
278 build wpa_supplicant for Windows (see vs2005 subdirectory)
279 * eloop_win: fixed unregistration of Windows events
280 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
281 at the end of RSN pre-authentication and added unregistration of
282 a Windows event to avoid getting eloop_win stuck with an invalid
284 * driver_ndis: added support for selecting AP based on BSSID
285 * added new environmental variable for wpa_cli action scripts:
286 WPA_CTRL_DIR is the current control interface directory
287 * driver_ndis: added support for using NDISUIO instead of WinPcap for
288 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
289 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
290 wpa_supplicant without requiring WinPcap; note that using NDISUIO
291 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
292 only one application to open the device
293 * changed NDIS driver naming to only include device GUID, e.g.,
294 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
295 specific \Device\NPF_ prefix before the GUID; the prefix is still
296 allowed for backwards compatibility, but it is not required anymore
297 when specifying the interface
298 * driver_ndis: re-initialize driver interface is the adapter is removed
299 and re-inserted [Bug 159]
300 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
301 big endian hosts [Bug 146]
304 * fixed EAP-GTC response to include correct user identity when run as
305 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
306 * driver_ndis: Fixed encryption mode configuration for unencrypted
307 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
308 refused to associate with open networks) [Bug 106]
309 * driver_ndis: use BSSID OID polling to detect when IBSS network is
310 formed even when ndis_events code is included since some NDIS drivers
311 do not generate media connect events in IBSS mode
312 * config_winreg: allow global ctrl_interface parameter to be configured
314 * config_winreg: added support for saving configuration data into
316 * added support for controlling network device operational state
317 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
318 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
319 that can use this information)
320 * driver_wext: added support for WE-21 change to SSID configuration
321 * driver_wext: fixed privacy configuration for static WEP keys mode
323 * added an optional driver_ops callback for MLME-SETPROTECTION.request
325 * added support for EAP-SAKE (no EAP method number allocated yet, so
326 this is using the same experimental type 255 as EAP-PSK)
327 * added support for dynamically loading EAP methods (.so files) instead
328 of requiring them to be statically linked in; this is disabled by
329 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
333 * do not try to use USIM APDUs when initializing PC/SC for SIM card
334 access for a network that has not enabled EAP-AKA
335 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
336 v0.5.1 due to the new support for expanded EAP types)
337 * added support for generating EAP Expanded Nak
338 * try to fetch scan results once before requesting new scan when
339 starting up in ap_scan=1 mode (this can speed up initial association
340 a lot with, e.g., madwifi-ng driver)
341 * added support for receiving EAPOL frames from a Linux bridge
342 interface (-bbr0 on command line)
343 * fixed EAPOL re-authentication for sessions that used PMKSA caching
344 * changed EAP method registration to use a dynamic list of methods
345 instead of a static list generated at build time
346 * fixed PMKSA cache deinitialization not to use freed memory when
347 removing PMKSA entries
348 * fixed a memory leak in EAP-TTLS re-authentication
349 * reject WPA/WPA2 message 3/4 if it does not include any valid
351 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
352 if the driver does not support SIOCSIWAUTH
355 * driver_test: added better support for multiple APs and STAs by using
356 a directory with sockets that include MAC address for each device in
357 the name (driver_param=test_dir=/tmp/test)
358 * added support for EAP expanded type (vendor specific EAP methods)
359 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
360 option can be changed if needed
361 * wpa_cli/wpa_gui: skip non-socket files in control directory when
362 using UNIX domain sockets; this avoids selecting an incorrect
363 interface (e.g., a PID file could be in this directory, even though
364 use of this directory for something else than socket files is not
366 * fixed TLS library deinitialization after RSN pre-authentication not
367 to disable TLS library for normal authentication
368 * driver_wext: Remove null-termination from SSID length if the driver
369 used it; some Linux drivers do this and they were causing problems in
370 wpa_supplicant not finding matching configuration block. This change
371 would break a case where the SSID actually ends in '\0', but that is
372 not likely to happen in real use.
373 * fixed PMKSA cache processing not to trigger deauthentication if the
374 current PMKSA cache entry is replaced with a valid new entry
375 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
376 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
379 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
380 * added experimental STAKey handshake implementation for IEEE 802.11e
381 direct link setup (DLS); note: this is disabled by default in both
382 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
384 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
385 decrypt AT_ENCR_DATA attributes correctly
386 * fixed EAP-AKA to allow resynchronization within the same session
387 * made code closer to ANSI C89 standard to make it easier to port to
388 other C libraries and compilers
389 * started moving operating system or C library specific functions into
390 wrapper functions defined in os.h and implemented in os_*.c to make
392 * wpa_supplicant can now be built with Microsoft Visual C++
393 (e.g., with the freely available Toolkit 2003 version or Visual
394 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
395 example makefile for nmake
396 * added support for using Windows registry for command line parameters
397 (CONFIG_MAIN=main_winsvc) and configuration data
398 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
399 contents; this version can be run both as a Windows service and as a
400 normal application; 'wpasvc.exe app' to start as applicant,
401 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
402 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
404 * made it possible to link ndis_events.exe functionality into
405 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
406 * added better support for multiple control interface backends
407 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
408 * fixed PC/SC code to use correct length for GSM AUTH command buffer
409 and to not use pioRecvPci with SCardTransmit() calls; these were not
410 causing visible problems with pcsc-lite, but Windows Winscard.dll
411 refused the previously used parameters; this fixes EAP-SIM and
412 EAP-AKA authentication using SIM/USIM card under Windows
413 * added new event loop implementation for Windows using
414 WaitForMultipleObject() instead of select() in order to allow waiting
415 for non-socket objects; this can be selected with
416 CONFIG_ELOOP=eloop_win in .config
417 * added support for selecting l2_packet implementation in .config
418 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
419 winpcap, freebsd, none)
420 * added new l2_packet implementation for WinPcap
421 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
422 reduce latency in EAPOL receive processing from about 100 ms to about
424 * added support for EAP-FAST key derivation using other ciphers than
425 RC4-128-SHA for authentication and AES128-SHA for provisioning
426 * added support for configuring CA certificate as DER file and as a
428 * fixed private key configuration as configuration blob and added
429 support for using PKCS#12 as a blob
430 * tls_gnutls: added support for using PKCS#12 files; added support for
432 * added support for loading trusted CA certificates from Windows
433 certificate store: ca_cert="cert_store://<name>", where <name> is
434 likely CA (Intermediate CA certificates) or ROOT (root certificates)
435 * added C version of ndis_events.cpp and made it possible to build this
436 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
437 easily on cross-compilation builds
438 * added wpasvc.exe into Windows binary release; this is an alternative
439 version of wpa_supplicant.exe with configuration backend using
440 Windows registry and with the entry point designed to run as a
442 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
443 wpasvc.exe and removed this additional tool from the Windows binary
444 release since it is not needed anymore
445 * load winscard.dll functions dynamically when building with MinGW
446 since MinGW does not yet include winscard library
448 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
449 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
450 and WinPcap to receive frames sent to PAE group address
451 * disable EAP state machine when IEEE 802.1X authentication is not used
452 in order to get rid of bogus "EAP failed" messages
453 * fixed OpenSSL error reporting to go through all pending errors to
454 avoid confusing reports of old errors being reported at later point
456 * fixed configuration file updating to not write empty variables
457 (e.g., proto or key_mgmt) that the file parser would not accept
458 * fixed ADD_NETWORK ctrl_iface command to use the same default values
459 for variables as empty network definitions read from config file
461 * fixed EAP state machine to not discard EAP-Failure messages in many
462 cases (e.g., during TLS handshake)
463 * fixed a infinite loop in private key reading if the configured file
464 cannot be parsed successfully
465 * driver_madwifi: added support for madwifi-ng
466 * wpa_gui: do not display password/PSK field contents
467 * wpa_gui: added CA certificate configuration
468 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
469 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
470 the new AP is using different WPA/RSN IE
471 * use longer timeout for IEEE 802.11 association to avoid problems with
472 drivers that may take more than five second to associate
475 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
476 RSN IE, but WPA IE would match with wpa_supplicant configuration
477 * added support for named configuration blobs in order to avoid having
478 to use file system for external files (e.g., certificates);
479 variables can be set to "blob://<blob name>" instead of file path to
480 use a named blob; supported fields: pac_file, client_cert,
482 * fixed RSN pre-authentication (it was broken in the clean up of WPA
483 state machine interface in v0.4.5)
484 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
485 sure the driver configures broadcast decryption correctly
486 * added ca_path (and ca_path2) configuration variables that can be used
487 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
488 system-wide trusted CA list
489 * added support for starting wpa_supplicant without a configuration
490 file (-C argument must be used to set ctrl_interface parameter for
491 this case; in addition, -p argument can be used to provide
492 driver_param; these new arguments can also be used with a
493 configuration to override the values from the configuration)
494 * added global control interface that can be optionally used for adding
495 and removing network interfaces dynamically (-g command line argument
496 for both wpa_supplicant and wpa_cli) without having to restart
497 wpa_supplicant process
499 - try to save configuration whenever something is modified
500 - added WEP key configuration
501 - added possibility to edit the current network configuration
502 * driver_ndis: fixed driver polling not to increase frequency on each
503 received EAPOL frame due to incorrectly cancelled timeout
504 * added simple configuration file examples (in examples subdirectory)
505 * fixed driver_wext.c to filter wireless events based on ifindex to
506 avoid interfaces receiving events from other interfaces
507 * delay sending initial EAPOL-Start couple of seconds to speed up
508 authentication for the most common case of Authenticator starting
509 EAP authentication immediately after association
512 * added a workaround for clearing keys with ndiswrapper to allow
513 roaming from WPA enabled AP to plaintext one
514 * added docbook documentation (doc/docbook) that can be used to
515 generate, e.g., man pages
516 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
517 PF_PACKET in order to prepare for network devices that do not use
518 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
519 * use receipt of EAPOL-Key frame as a lower layer success indication
520 for EAP state machine to allow recovery from dropped EAP-Success
522 * cleaned up internal EAPOL frame processing by not including link
523 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
524 header is added only when transmitted the frame; this makes it easier
525 to use wpa_supplicant on link layers that use different header than
527 * updated EAP-PSK to use draft 9 by default since this can now be
528 tested with hostapd; removed support for draft 3, including
529 server_nai configuration option from network blocks
530 * driver_wired: add PAE address to the multicast address list in order
531 to be able to receive EAPOL frames with drivers that do not include
532 these multicast addresses by default
533 * driver_wext: add support for WE-19
534 * added support for multiple configuration backends (CONFIG_BACKEND
535 option); currently, only 'file' is supported (i.e., the format used
536 in wpa_supplicant.conf)
537 * added support for updating configuration ('wpa_cli save_config');
538 this is disabled by default and can be enabled with global
539 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
540 and wpa_gui to store the configuration changes in a permanent store
541 * added GET_NETWORK ctrl_iface command
542 (e.g., 'wpa_cli get_network 0 ssid')
545 * replaced OpenSSL patch for EAP-FAST support
546 (openssl-tls-extensions.patch) with a more generic and correct
547 patch (the new patch is not compatible with the previous one, so the
548 OpenSSL library will need to be patched with the new patch in order
549 to be able to build wpa_supplicant with EAP-FAST support)
550 * added support for using Windows certificate store (through CryptoAPI)
551 for client certificate and private key operations (EAP-TLS)
552 (see wpa_supplicant.conf for more information on how to configure
553 this with private_key)
554 * ported wpa_gui to Windows
555 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
556 built with the open source version of the Qt4 for Windows
557 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
558 with drivers that do not support WPA
559 * ndis_events: fixed Windows 2000 support
560 * added support for enabling/disabling networks from the list of all
561 configured networks ('wpa_cli enable_network <network id>' and
562 'wpa_cli disable_network <network id>')
563 * added support for adding and removing network from the current
564 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
565 <network id>'); added networks are disabled by default and they can
566 be enabled with enable_network command once the configuration is done
567 for the new network; note: configuration file is not yet updated, so
568 these new networks are lost when wpa_supplicant is restarted
569 * added support for setting network configuration parameters through
570 the control interface, for example:
571 wpa_cli set_network 0 ssid "\"my network\""
572 * fixed parsing of strings that include both " and # within double
573 quoted area (e.g., "start"#end")
574 * added EAP workaround for PEAP session resumption: allow outer,
575 i.e., not tunneled, EAP-Success to terminate session since; this can
576 be disabled with eap_workaround=0
577 (this was allowed for PEAPv1 before, but now it is also allowed for
578 PEAPv0 since at least one RADIUS authentication server seems to be
579 doing this for PEAPv0, too)
580 * wpa_gui: added preliminary support for adding new networks to the
581 wpa_supplicant configuration (double click on the scan results to
582 open network configuration)
585 * removed interface for external EAPOL/EAP supplicant (e.g.,
586 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
587 anymore and is unlikely to be used by anyone
588 * driver_ndis: fixed WinPcap 3.0 support
589 * fixed build with CONFIG_DNET_PCAP=y on Linux
590 * l2_packet: moved different implementations into separate files
594 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
595 (note: ipw2100-1.1.0 is likely to require an update to work with
597 * added support for using ap_scan=2 mode with multiple network blocks;
598 wpa_supplicant will go through the networks one by one until the
599 driver reports a successful association; this uses the same order for
600 networks as scan_ssid=1 scans, i.e., the priority field is ignored
601 and the network block order in the file is used instead
602 * fixed a potential issue in RSN pre-authentication ending up using
603 freed memory if pre-authentication times out
604 * added support for matching alternative subject name extensions of the
605 authentication server certificate; new configuration variables
606 altsubject_match and altsubject_match2
607 * driver_ndis: added support for IEEE 802.1X authentication with wired
609 * added support for querying private key password (EAP-TLS) through the
610 control interface (wpa_cli/wpa_gui) if one is not included in the
612 * driver_broadcom: fixed couple of memory leaks in scan result
614 * EAP-PAX is now registered as EAP type 46
615 * fixed EAP-PAX MAC calculation
616 * fixed EAP-PAX CK and ICK key derivation
617 * added support for using password with EAP-PAX (as an alternative to
618 entering key with eappsk); SHA-1 hash of the password will be used as
620 * added support for arbitrary driver interface parameters through the
621 configuration file with a new driver_param field; this adds a new
622 driver_ops function set_param()
623 * added possibility to override l2_packet module with driver interface
624 API (new send_eapol handler); this can be used to implement driver
625 specific TX/RX functions for EAPOL frames
626 * fixed ctrl_interface_group processing for the case where gid is
627 entered as a number, not group name
628 * driver_test: added support for testing hostapd with wpa_supplicant
629 by using test driver interface without any kernel drivers or network
633 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
634 packets to be encrypted; this was apparently broken by the changed
635 ioctl order in v0.4.0
636 * driver_madwifi: added preliminary support for compiling against 'BSD'
637 branch of madwifi CVS tree
638 * added support for EAP-MSCHAPv2 password retries within the same EAP
639 authentication session
640 * added support for password changes with EAP-MSCHAPv2 (used when the
641 password has expired)
642 * added support for reading additional certificates from PKCS#12 files
643 and adding them to the certificate chain
644 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
646 * fixed a possible double free in EAP-TTLS fast-reauthentication when
647 identity or password is entered through control interface
648 * display EAP Notification messages to user through control interface
649 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
650 * added GUI version of wpa_cli, wpa_gui; this is not build
651 automatically with 'make'; use 'make wpa_gui' to build (this requires
652 Qt development tools)
653 * added 'disconnect' command to control interface for setting
654 wpa_supplicant in state where it will not associate before
655 'reassociate' command has been used
656 * added support for selecting a network from the list of all configured
657 networks ('wpa_cli select_network <network id>'; this disabled all
658 other networks; to re-enable, 'wpa_cli select_network any')
659 * added support for getting scan results through control interface
660 * added EAP workaround for PEAPv1 session resumption: allow outer,
661 i.e., not tunneled, EAP-Success to terminate session since; this can
662 be disabled with eap_workaround=0
664 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
665 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
666 used to reduce the size of the wpa_supplicant considerably if
667 debugging code is not needed
668 * fixed EAPOL-Key validation to drop packets with invalid Key Data
669 Length; such frames could have crashed wpa_supplicant due to buffer
671 * added support for wired authentication (IEEE 802.1X on wired
672 Ethernet); driver interface 'wired'
673 * obsoleted set_wpa() handler in the driver interface API (it can be
674 replaced by moving enable/disable functionality into init()/deinit())
675 (calls to set_wpa() are still present for backwards compatibility,
676 but they may be removed in the future)
677 * driver_madwifi: fixed association in plaintext mode
678 * modified the EAP workaround that accepts EAP-Success with incorrect
679 Identifier to be even less strict about verification in order to
680 interoperate with some authentication servers
681 * added support for sending TLS alerts
682 * added support for 'any' SSID wildcard; if ssid is not configured or
683 is set to an empty string, any SSID will be accepted for non-WPA AP
684 * added support for asking PIN (for SIM) from frontends (e.g.,
685 wpa_cli); if a PIN is needed, but not included in the configuration
686 file, a control interface request is sent and EAP processing is
687 delayed until the PIN is available
688 * added support for using external devices (e.g., a smartcard) for
689 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
690 new wpa_supplicant.conf variables:
691 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
692 - network: engine, engine_id, key_id
693 * added experimental support for EAP-PAX
694 * added monitor mode for wpa_cli (-a<path to a program to run>) that
695 allows external commands (e.g., shell scripts) to be run based on
696 wpa_supplicant events, e.g., when authentication has been completed
697 and data connection is ready; other related wpa_cli arguments:
698 -B (run in background), -P (write PID file); wpa_supplicant has a new
699 command line argument (-W) that can be used to make it wait until a
700 control interface command is received in order to avoid missing
702 * added support for opportunistic WPA2 PMKSA key caching (disabled by
703 default, can be enabled with proactive_key_caching=1)
704 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
705 Authenticator rejects PMKSA caching attempt and the driver is not
706 using assoc_info events
707 * added -P<pid file> argument for wpa_supplicant to write the current
708 process id into a file
710 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
711 * added new phase1 option parameter, include_tls_length=1, to force
712 wpa_supplicant to add TLS Message Length field to all TLS messages
713 even if the packet is not fragmented; this may be needed with some
714 authentication servers
715 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
716 using drivers that take care of AP selection (e.g., when using
718 * fixed reprocessing of pending request after ctrl_iface requests for
719 identity/password/otp
720 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
721 EAP-PEAP and EAP-TTLS
722 * all drivers using driver_wext: set interface up and select Managed
723 mode when starting wpa_supplicant; set interface down when exiting
724 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
725 ipw2100 and ipw2200; please note that this also changed the
726 configuration variable in .config to CONFIG_DRIVER_IPW
729 * fixed a busy loop introduced in v0.3.5 for scan result processing
730 when no matching AP is found
733 * added a workaround for an interoperability issue with a Cisco AP
735 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
736 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
737 retransmission of dropped frames)
738 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
739 (e.g., segfault when processing EAPOL-Key frames)
740 * fixed EAP workaround and fast reauthentication configuration for
741 RSN pre-authentication; previously these were disabled and
742 pre-authentication would fail if the used authentication server
743 requires EAP workarounds
744 * added support for blacklisting APs that fail or timeout
745 authentication in ap_scan=1 mode so that all APs are tried in cases
746 where the ones with strongest signal level are failing authentication
747 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
748 authentication attempt
749 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
750 in the previous authentication (previously, only Phase 1 success was
754 * added preliminary support for IBSS (ad-hoc) mode configuration
755 (mode=1 in network block); this included a new key_mgmt mode
756 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
757 key management; see wpa_supplicant.conf for more details and an
758 example on how to configure this (note: this is currently implemented
759 only for driver_hostapd.c, but the changes should be trivial to add
760 in associate() handler for other drivers, too (assuming the driver
762 * added preliminary port for native Windows (i.e., no cygwin) using
766 * added optional support for GNU Readline and History Libraries for
767 wpa_cli (CONFIG_READLINE)
768 * cleaned up EAP state machine <-> method interface and number of
769 small problems with error case processing not terminating on
770 EAP-Failure but waiting for timeout
771 * added couple of workarounds for interoperability issues with a
772 Cisco AP when using WPA2
773 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
774 Note: This requires a patch for openssl to add support for TLS
775 extensions and number of workarounds for operations without
776 certificates. Proof of concept type of experimental patch is
777 included in openssl-tls-extensions.patch.
780 * fixed private key loading for cases where passphrase is not set
781 * fixed Windows/cygwin L2 packet handler freeing; previous version
782 could cause a segfault when RSN pre-authentication was completed
783 * added support for PMKSA caching with drivers that generate RSN IEs
784 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
785 but similar code can be easily added to driver_ndiswrapper.c once
786 ndiswrapper gets full support for RSN PMKSA caching
787 * improved recovery from PMKID mismatches by requesting full EAP
788 authentication in case of failed PMKSA caching attempt
789 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
790 (this requires that ndis_events is ran while wpa_supplicant is
792 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
793 * added support for driver interfaces to replace the interface name
794 based on driver/OS specific mapping, e.g., in case of driver_ndis,
795 this allows the beginning of the adapter description to be used as
797 * added support for CR+LF (Windows-style) line ends in configuration
799 * driver_ndis: enable radio before starting scanning, disable radio
801 * modified association event handler to set portEnabled = FALSE before
802 clearing port Valid in order to reset EAP state machine and avoid
803 problems with new authentication getting ignored because of state
804 machines ending up in AUTHENTICATED/SUCCESS state based on old
806 * added support for driver events to add PMKID candidates in order to
807 allow drivers to give priority to most likely roaming candidates
808 * driver_hostap: moved PrivacyInvoked configuration to associate()
809 function so that this will not be set for plaintext connections
810 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
811 interface can distinguish plaintext and IEEE 802.1X (no WPA)
813 * fixed static WEP key configuration to use broadcast/default type for
814 all keys (previously, the default TX key was configured as pairwise/
816 * driver_ndis: added legacy WPA capability detection for non-WPA2
818 * added support for setting static WEP keys for IEEE 802.1X without
819 dynamic WEP keying (eapol_flags=0)
822 * added support for reading PKCS#12 (PFX) files (as a replacement for
823 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
824 * fixed compilation with CONFIG_PCSC=y
825 * added new ap_scan mode, ap_scan=2, for drivers that take care of
826 association, but need to be configured with security policy and SSID,
827 e.g., ndiswrapper and NDIS driver; this mode should allow such
828 drivers to work with hidden SSIDs and optimized roaming; when
829 ap_scan=2 is used, only the first network block in the configuration
830 file is used and this configuration should have explicit security
831 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
832 group, proto variables
833 * added experimental port of wpa_supplicant for Windows
834 - driver_ndis.c driver interface (NDIS OIDs)
835 - currently, this requires cygwin and WinPcap
836 - small utility, win_if_list, can be used to get interface name
837 * control interface can now be removed at build time; add
838 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
839 * optional Xsupplicant interface can now be removed at build time;
840 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
841 * added auth_alg to driver interface associate() parameters to make it
842 easier for drivers to configure authentication algorithm as part of
845 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
846 * driver_broadcom: added new driver interface for Broadcom wl.o driver
847 (a generic driver for Broadcom IEEE 802.11a/g cards)
848 * wpa_cli: fixed parsing of -p <path> command line argument
849 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
850 ACK, not tunneled EAP-Success (of which only the first byte was
851 actually send due to a bug in previous code); this seems to
852 interoperate with most RADIUS servers that implements PEAPv1
853 * PEAPv1: added support for terminating PEAP authentication on tunneled
854 EAP-Success message; this can be configured by adding
855 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
856 (some RADIUS servers require this whereas others require a tunneled
858 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
859 the old label for key derivation; previously, the default was 1,
860 but it looks like most existing PEAPv1 implementations use the old
861 label which is thus more suitable default option
862 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
863 * fixed parsing of wep_tx_keyidx
864 * added support for configuring list of allowed Phase 2 EAP types
865 (for both EAP-PEAP and EAP-TTLS) instead of only one type
866 * added support for configuring IEEE 802.11 authentication algorithm
867 (auth_alg; mainly for using Shared Key authentication with static
869 * added support for EAP-AKA (with UMTS SIM)
870 * fixed couple of errors in PCSC handling that could have caused
871 random-looking errors for EAP-SIM
872 * added support for EAP-SIM pseudonyms and fast re-authentication
873 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
875 * added support for EAP-SIM with two challanges
876 (phase1="sim_min_num_chal=3" can be used to require three challenges)
877 * added support for configuring DH/DSA parameters for an ephemeral DH
878 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
879 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
880 and optional DH key exchange to achieve forward secracy with RSA keys
881 * added support for matching subject of the authentication server
882 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
883 configuration variables subject_match and subject_match2
884 * changed SSID configuration in driver_wext.c (used by many driver
885 interfaces) to use ssid_len+1 as the length for SSID since some Linux
887 * fixed couple of unaligned reads in scan result parsing to fix WPA
888 connection on some platforms (e.g., ARM)
889 * added driver interface for Intel ipw2100 driver
890 * added support for LEAP with WPA
891 * added support for larger scan results report (old limit was 4 kB of
892 data, i.e., about 35 or so APs) when using Linux wireless extensions
894 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
895 only if there is a PMKSA cache entry for the current AP
896 * fixed error handling for case where reading of scan results fails:
897 must schedule a new scan or wpa_supplicant will remain waiting
899 * changed debug output to remove shared password/key material by
900 default; all key information can be included with -K command line
901 argument to match the previous behavior
902 * added support for timestamping debug log messages (disabled by
903 default, can be enabled with -t command line argument)
904 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
905 if keys are not configured to be used; this fixes IEEE 802.1X mode
906 with drivers that use this information to configure whether Privacy
907 bit can be in Beacon frames (e.g., ndiswrapper)
908 * avoid clearing driver keys if no keys have been configured since last
909 key clear request; this seems to improve reliability of group key
910 handshake for ndiswrapper & NDIS driver which seems to be suffering
911 of some kind of timing issue when the keys are cleared again after
913 * changed driver interface API:
914 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
915 version is being used (now, this is set to 2; previously, it was
917 - pass pointer to private data structure to all calls
918 - the new API is not backwards compatible; all in-tree driver
919 interfaces has been converted to the new API
920 * added support for controlling multiple interfaces (radios) per
921 wpa_supplicant process; each interface needs to be listed on the
922 command line (-c, -i, -D arguments) with -N as a separator
923 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
924 * added a workaround for EAP servers that incorrectly use same Id for
925 sequential EAP packets
926 * changed libpcap/libdnet configuration to use .config variable,
927 CONFIG_DNET_PCAP, instead of requiring Makefile modification
928 * improved downgrade attack detection in IE verification of msg 3/4:
929 verify both WPA and RSN IEs, if present, not only the selected one;
930 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
931 Probe Response frame, and RSN is enabled in wpa_supplicant
933 * fixed WPA msg 3/4 processing to allow Key Data field contain other
934 IEs than just one WPA IE
935 * added support for FreeBSD and driver interface for the BSD net80211
936 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
937 required kernel mods have not yet been committed
938 * made EAP workarounds configurable; enabled by default, can be
939 disabled with network block option eap_workaround=0
941 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
942 * resolved couple of interoperability issues with EAP-PEAPv1 and
943 Phase 2 (inner EAP) fragment reassembly
944 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
945 AP is using non-zero key index for the unicast key and key index zero
946 for the broadcast key
947 * driver_hostap: fixed IEEE 802.1X WEP key updates and
948 re-authentication by allowing unencrypted EAPOL frames when not using
950 * added a new driver interface, 'wext', which uses only standard,
951 driver independent functionality in Linux wireless extensions;
952 currently, this can be used only for non-WPA IEEE 802.1X mode, but
953 eventually, this is to be extended to support full WPA/WPA2 once
954 Linux wireless extensions get support for this
955 * added support for mode in which the driver is responsible for AP
956 scanning and selection; this is disabled by default and can be
957 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
958 this mode can be used, e.g., with generic 'wext' driver interface to
959 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
960 supporting wireless extensions.
961 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
962 operation with an AP that does not include SSID in the Beacon frames)
963 * added support for new EAP authentication methods:
964 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
965 * added support for asking one-time-passwords from frontends (e.g.,
966 wpa_cli); this 'otp' command works otherwise like 'password' command,
967 but the password is used only once and the frontend will be asked for
968 a new password whenever a request from authenticator requires a
969 password; this can be used with both EAP-OTP and EAP-GTC
970 * changed wpa_cli to automatically re-establish connection so that it
971 does not need to be re-started when wpa_supplicant is terminated and
973 * improved user data (identity/password/otp) requests through
974 frontends: process pending EAPOL packets after getting new
975 information so that full authentication does not need to be
976 restarted; in addition, send pending requests again whenever a new
978 * changed control frontends to use a new directory for socket files to
979 make it easier for wpa_cli to automatically select between interfaces
980 and to provide access control for the control interface;
981 wpa_supplicant.conf: ctrl_interface is now a path
982 (/var/run/wpa_supplicant is the recommended path) and
983 ctrl_interface_group can be used to select which group gets access to
984 the control interface;
985 wpa_cli: by default, try to connect to the first interface available
986 in /var/run/wpa_supplicant; this path can be overriden with -p option
987 and an interface can be selected with -i option (i.e., in most common
988 cases, wpa_cli does not need to get any arguments)
989 * added support for LEAP
990 * added driver interface for Linux ndiswrapper
991 * added priority option for network blocks in the configuration file;
992 this allows networks to be grouped based on priority (the scan
993 results are searched for matches with network blocks in this order)
996 * sort scan results to improve AP selection
997 * fixed control interface socket removal for some error cases
998 * improved scan requesting and authentication timeout
999 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1001 * PEAP version can now be forced with phase1="peapver=<ver>"
1002 (mostly for testing; by default, the highest version supported by
1003 both the Supplicant and Authentication Server is selected
1005 * added support for madwifi driver (Atheros ar521x)
1006 * added a workaround for cases where AP sets Install Tx/Rx bit for
1007 WPA Group Key messages when pairwise keys are used (without this,
1008 the Group Key would be used for Tx and the AP would drop frames
1010 * added GSM SIM/USIM interface for GSM authentication algorithm for
1011 EAP-SIM; this requires pcsc-lite
1012 * added support for ATMEL AT76C5XXx driver
1013 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1014 does not include key data in the EAPOL-Key frame (i.e., part of
1015 EAP keying material is used as data encryption key)
1016 * added support for using plaintext and static WEP networks
1020 * added support for new EAP authentication methods:
1021 EAP-TTLS/EAP-MD5-Challenge
1023 EAP-TTLS/EAP-MSCHAPv2
1031 EAP-PEAP/MD5-Challenge
1033 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1034 * added support for anonymous identity (to be used when identity is
1035 sent in plaintext; real identity will be used within TLS protected
1036 tunnel (e.g., with EAP-TTLS)
1037 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1038 * added support for requesting identity and password information using
1039 control interface; in other words, the password for EAP-PEAP or
1040 EAP-TTLS does not need to be included in the configuration file since
1041 a frontand (e.g., wpa_cli) can ask it from the user
1042 * improved RSN pre-authentication to use a candidate list and process
1043 all candidates from each scan; not only one per scan
1044 * fixed RSN IE and WPA IE capabilities field parsing
1045 * ignore Tx bit in GTK IE when Pairwise keys are used
1046 * avoid making new scan requests during IEEE 802.1X negotiation
1047 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1048 with TLS support (this replaces the included implementation with
1049 library code to save about 8 kB since the library code is needed
1051 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1052 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1055 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1057 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1058 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1059 - EAP-MD5 (cannot be used with WPA-RADIUS)
1060 [draft-ietf-eap-rfc2284bis-09.txt]
1061 - EAP-TLS [RFC 2716]
1062 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1063 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1064 [draft-kamath-pppext-eap-mschapv2-00.txt]
1065 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1066 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1067 - new configuration file options: eap, identity, password, ca_cert,
1068 client_cert, privatekey, private_key_passwd
1069 - Xsupplicant is not required anymore, but it can be used by
1070 disabling the internal IEEE 802.1X Supplicant with -e command line
1072 - this code is not included in the default build; Makefile need to
1073 be edited for this (uncomment lines for selected functionality)
1074 - EAP-TLS and EAP-PEAP require openssl libraries
1075 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1076 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1077 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1078 EAPOL-Key frames instead of WPA key handshakes)
1079 * added support for IEEE 802.11i/RSN (WPA2)
1080 - improved PTK Key Handshake
1081 - PMKSA caching, pre-authentication
1082 * fixed wpa_supplicant to ignore possible extra data after WPA
1083 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1084 TPTK' error from message 3 of 4-Way Handshake in case the AP
1085 includes extra data after the EAPOL-Key)
1086 * added interface for external programs (frontends) to control
1088 - CLI example (wpa_cli) with interactive mode and command line
1090 - replaced SIGUSR1 status/statistics with the new control interface
1091 * made some feature compile time configurable
1092 - .config file for make
1093 - driver interfaces (hostap, hermes, ..)
1094 - EAPOL/EAP functions
1097 * Initial version of wpa_supplicant
