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
10 * added fragmentation support for EAP-TNC
11 * added support for parsing PKCS #8 formatted private keys into the
12 internal TLS implementation (both PKCS #1 RSA key and PKCS #8
13 encapsulated RSA key can now be used)
16 * removed 'nai' and 'eappsk' network configuration variables that were
17 previously used for configuring user identity and key for EAP-PSK,
18 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
19 replacement for 'nai' (if old configuration used a separate
20 'identity' value, that would now be configured as
21 'anonymous_identity'). 'password' field is now used as the
22 replacement for 'eappsk' (it can also be set using hexstring to
23 present random binary data)
24 * removed '-w' command line parameter (wait for interface to be added,
25 if needed); cleaner way of handling this functionality is to use an
26 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
27 when an interface is added
28 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
29 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
30 indicating when new scan results become available
31 * added new ctrl_iface command, BSS, to allow scan results to be
32 fetched without hitting the message size limits (this command
33 can be used to iterate through the scan results one BSS at the time)
34 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
35 attributes in EAP-SIM Start/Response when using fast reauthentication
36 * fixed EAPOL not to end up in infinite loop when processing dynamic
37 WEP keys with IEEE 802.1X
38 * fixed problems in getting NDIS events from WMI on Windows 2000
41 * added support for Makefile builds to include debug-log-to-a-file
42 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
43 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
44 lengths properly to avoid potential crash caused by invalid messages
45 * added data structure for storing allocated buffers (struct wpabuf);
46 this does not affect wpa_supplicant usage, but many of the APIs
47 changed and various interfaces (e.g., EAP) is not compatible with old
49 * added support for protecting EAP-AKA/Identity messages with
50 AT_CHECKCODE (optional feature in RFC 4187)
51 * added support for protected result indication with AT_RESULT_IND for
52 EAP-SIM and EAP-AKA (phase1="result_ind=1")
53 * added driver_wext workaround for race condition between scanning and
54 association with drivers that take very long time to scan all
55 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
56 using a longer hardcoded timeout for the scan if the driver supports
57 notifications for scan completion (SIOCGIWSCAN event); this helps,
58 e.g., in cases where wpa_supplicant and madwifi driver ended up in
59 loop where the driver did not even try to associate
60 * stop EAPOL timer tick when no timers are in use in order to reduce
61 power consumption (no need to wake up the process once per second)
63 * added support for privilege separation (run only minimal part of
64 wpa_supplicant functionality as root and rest as unprivileged,
65 non-root process); see 'Privilege separation' in README for details;
66 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
68 * changed scan results data structure to include all information
69 elements to make it easier to support new IEs; old get_scan_result()
70 driver_ops is still supported for backwards compatibility (results
71 are converted internally to the new format), but all drivers should
72 start using the new get_scan_results2() to make them more likely to
73 work with new features
74 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
75 application, i.e., it does not require Qt3Support anymore; Windows
76 binary of wpa_gui.exe is now from this directory and only requires
77 QtCore4.dll and QtGui4.dll libraries
78 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
79 available as a separate package to make wpa_gui installation easier:
80 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
81 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
82 only shared key/password authentication is supported in this version
85 * added support for configuring password as NtPasswordHash
86 (16-byte MD4 hash of password) in hash:<32 hex digits> format
87 * added support for fallback from abbreviated TLS handshake to
88 full handshake when using EAP-FAST (e.g., due to an expired
90 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
91 draft (draft-ietf-emu-eap-gpsk-07.txt)
92 * added support for drivers that take care of RSN 4-way handshake
93 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
94 WPA_ALG_PMK in set_key)
95 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
96 .config); this version supports only ap_scan=2 mode and allow the
97 driver to take care of the 4-way handshake
98 * fixed a buffer overflow in parsing TSF from scan results when using
99 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
101 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
102 * fixed an integer overflow issue in the ASN.1 parser used by the
103 (experimental) internal TLS implementation to avoid a potential
105 * fixed a race condition with -W option (wait for a control interface
106 monitor before starting) that could have caused the first messages to
108 * added support for processing TNCC-TNCS-Messages to report
109 recommendation (allow/none/isolate) when using TNC [Bug 243]
112 * added network configuration parameter 'frequency' for setting
113 initial channel for IBSS (adhoc) networks
114 * added experimental IEEE 802.11r/D6.0 support
115 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
116 * updated EAP-PSK to use the IANA-allocated EAP type 47
117 * fixed EAP-PAX key derivation
118 * fixed EAP-PSK bit ordering of the Flags field
119 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
120 tunnelled identity request (previously, the identifier from the outer
121 method was used, not the tunnelled identifier which could be
123 * added support for fragmentation of outer TLS packets during Phase 2
124 of EAP-PEAP/TTLS/FAST
125 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
126 * added support for EAP-FAST authentication with inner methods that
127 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
128 for PAC provisioning)
129 * added support for authenticated EAP-FAST provisioning
130 * added support for configuring maximum number of EAP-FAST PACs to
131 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
132 * added support for storing EAP-FAST PACs in binary format
133 (fast_pac_format=binary in phase1 string)
134 * fixed dbus ctrl_iface to validate message interface before
135 dispatching to avoid a possible segfault [Bug 190]
136 * fixed PeerKey key derivation to use the correct PRF label
137 * updated Windows binary build to link against OpenSSL 0.9.8d and
138 added support for EAP-FAST
139 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
140 draft (draft-ietf-emu-eap-gpsk-04.txt)
141 * fixed EAP-AKA Notification processing to allow Notification to be
142 processed after AKA Challenge response has been sent
143 * updated to use IEEE 802.11w/D2.0 for management frame protection
145 * fixed EAP-TTLS implementation not to crash on use of freed memory
146 if TLS library initialization fails
147 * added support for EAP-TNC (Trusted Network Connect)
148 (this version implements the EAP-TNC method and EAP-TTLS changes
149 needed to run two methods in sequence (IF-T) and the IF-IMC and
150 IF-TNCCS interfaces from TNCC)
153 * added experimental, integrated TLSv1 client implementation with the
154 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
155 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
156 .config); this can be useful, e.g., if the target system does not
157 have a suitable TLS library and a minimal code size is required
158 (total size of this internal TLS/crypto code is bit under 50 kB on
159 x86 and the crypto code is shared by rest of the supplicant so some
160 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
161 * removed STAKey handshake since PeerKey handshake has replaced it in
162 IEEE 802.11ma and there are no known deployments of STAKey
163 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
164 draft (draft-ietf-emu-eap-gpsk-01.txt)
165 * added preliminary implementation of IEEE 802.11w/D1.0 (management
167 (Note: this requires driver support to work properly.)
168 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
169 * fixed Windows named pipes ctrl_iface to not stop listening for
170 commands if client program opens a named pipe and closes it
171 immediately without sending a command
172 * fixed USIM PIN status determination for the case that PIN is not
173 needed (this allows EAP-AKA to be used with USIM cards that do not
175 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
176 be used with cards that do not support file selection based on
178 * added support for matching the subjectAltName of the authentication
179 server certificate against multiple name components (e.g.,
180 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
181 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
182 affects IEEE 802.1X with dynamic WEP keys)
183 * changed ctrl_iface network configuration 'get' operations to not
184 return password/key material; if these fields are requested, "*"
185 will be returned if the password/key is set, but the value of the
186 parameter is not exposed
189 * added support for building Windows version with UNICODE defined
190 (wide-char functions)
191 * driver_ndis: fixed static WEP configuration to avoid race condition
192 issues with some NDIS drivers between association and setting WEP
194 * driver_ndis: added validation for IELength value in scan results to
195 avoid crashes when using buggy NDIS drivers [Bug 165]
196 * fixed Release|Win32 target in the Visual Studio project files
197 (previously, only Debug|Win32 target was set properly)
198 * changed control interface API call wpa_ctrl_pending() to allow it to
199 return -1 on error (e.g., connection lost); control interface clients
200 will need to make sure that they verify that the value is indeed >0
201 when determining whether there are pending messages
202 * added an alternative control interface backend for Windows targets:
203 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
204 control interface mechanism for Windows builds (previously, UDP to
206 * changed ctrl_interface configuration for UNIX domain sockets:
207 - deprecated ctrl_interface_group variable (it may be removed in
209 - allow both directory and group be configured with ctrl_interface
210 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
211 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
212 case when group is not changed
213 * added support for controlling more than one interface per process in
215 * added a workaround for a case where the AP is using unknown address
216 (e.g., MAC address of the wired interface) as the source address for
217 EAPOL-Key frames; previously, that source address was used as the
218 destination for EAPOL-Key frames and in key derivation; now, BSSID is
219 used even if the source address does not match with it
220 (this resolves an interoperability issue with Thomson SpeedTouch 580)
221 * added a workaround for UDP-based control interface (which was used in
222 Windows builds before this release) to prevent packets with forged
223 addresses from being accepted as local control requests
224 * removed ndis_events.cpp and possibility of using external
225 ndis_events.exe; C version (ndis_events.c) is fully functional and
226 there is no desire to maintain two separate versions of this
228 * ndis_events: Changed NDIS event notification design to use WMI to
229 learn the adapter description through Win32_PnPEntity class; this
230 should fix some cases where the adapter name was not recognized
231 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
233 * fixed selection of the first network in ap_scan=2 mode; previously,
234 wpa_supplicant could get stuck in SCANNING state when only the first
235 network for enabled (e.g., after 'wpa_cli select_network 0')
236 * winsvc: added support for configuring ctrl_interface parameters in
237 registry (ctrl_interface string value in
238 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
239 required to enable control interface (previously, this was hardcoded
241 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
242 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
245 * fixed build with CONFIG_STAKEY=y [Bug 143]
246 * added support for doing MLME (IEEE 802.11 management frame
247 processing) in wpa_supplicant when using Devicescape IEEE 802.11
248 stack (wireless-dev.git tree)
249 * added a new network block configuration option, fragment_size, to
250 configure the maximum EAP fragment size
251 * driver_ndis: Disable WZC automatically for the selected interface to
252 avoid conflicts with two programs trying to control the radio; WZC
253 will be re-enabled (if it was enabled originally) when wpa_supplicant
255 * added an experimental TLSv1 client implementation
256 (CONFIG_TLS=internal) that can be used instead of an external TLS
257 library, e.g., to reduce total size requirement on systems that do
258 not include any TLS library by default (this is not yet complete;
259 basic functionality is there, but certificate validation is not yet
261 * added PeerKey handshake implementation for IEEE 802.11e
262 direct link setup (DLS) to replace STAKey handshake
263 * fixed WPA PSK update through ctrl_iface for the case where the old
264 PSK was derived from an ASCII passphrase and the new PSK is set as
265 a raw PSK (hex string)
266 * added new configuration option for identifying which network block
267 was used (id_str in wpa_supplicant.conf; included on
268 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
269 variable in wpa_cli action scripts; in addition WPA_ID variable is
270 set to the current unique identifier that wpa_supplicant assigned
271 automatically for the network and that can be used with
272 GET_NETWORK/SET_NETWORK ctrl_iface commands)
273 * wpa_cli action script is now called only when the connect/disconnect
274 status changes or when associating with a different network
275 * fixed configuration parser not to remove CCMP from group cipher list
276 if WPA-None (adhoc) is used (pairwise=NONE in that case)
277 * fixed integrated NDIS events processing not to hang the process due
278 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
279 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
280 draft-clancy-emu-eap-shared-secret-00.txt)
281 * added Microsoft Visual Studio 2005 solution and project files for
282 build wpa_supplicant for Windows (see vs2005 subdirectory)
283 * eloop_win: fixed unregistration of Windows events
284 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
285 at the end of RSN pre-authentication and added unregistration of
286 a Windows event to avoid getting eloop_win stuck with an invalid
288 * driver_ndis: added support for selecting AP based on BSSID
289 * added new environmental variable for wpa_cli action scripts:
290 WPA_CTRL_DIR is the current control interface directory
291 * driver_ndis: added support for using NDISUIO instead of WinPcap for
292 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
293 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
294 wpa_supplicant without requiring WinPcap; note that using NDISUIO
295 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
296 only one application to open the device
297 * changed NDIS driver naming to only include device GUID, e.g.,
298 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
299 specific \Device\NPF_ prefix before the GUID; the prefix is still
300 allowed for backwards compatibility, but it is not required anymore
301 when specifying the interface
302 * driver_ndis: re-initialize driver interface is the adapter is removed
303 and re-inserted [Bug 159]
304 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
305 big endian hosts [Bug 146]
308 * fixed EAP-GTC response to include correct user identity when run as
309 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
310 * driver_ndis: Fixed encryption mode configuration for unencrypted
311 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
312 refused to associate with open networks) [Bug 106]
313 * driver_ndis: use BSSID OID polling to detect when IBSS network is
314 formed even when ndis_events code is included since some NDIS drivers
315 do not generate media connect events in IBSS mode
316 * config_winreg: allow global ctrl_interface parameter to be configured
318 * config_winreg: added support for saving configuration data into
320 * added support for controlling network device operational state
321 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
322 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
323 that can use this information)
324 * driver_wext: added support for WE-21 change to SSID configuration
325 * driver_wext: fixed privacy configuration for static WEP keys mode
327 * added an optional driver_ops callback for MLME-SETPROTECTION.request
329 * added support for EAP-SAKE (no EAP method number allocated yet, so
330 this is using the same experimental type 255 as EAP-PSK)
331 * added support for dynamically loading EAP methods (.so files) instead
332 of requiring them to be statically linked in; this is disabled by
333 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
337 * do not try to use USIM APDUs when initializing PC/SC for SIM card
338 access for a network that has not enabled EAP-AKA
339 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
340 v0.5.1 due to the new support for expanded EAP types)
341 * added support for generating EAP Expanded Nak
342 * try to fetch scan results once before requesting new scan when
343 starting up in ap_scan=1 mode (this can speed up initial association
344 a lot with, e.g., madwifi-ng driver)
345 * added support for receiving EAPOL frames from a Linux bridge
346 interface (-bbr0 on command line)
347 * fixed EAPOL re-authentication for sessions that used PMKSA caching
348 * changed EAP method registration to use a dynamic list of methods
349 instead of a static list generated at build time
350 * fixed PMKSA cache deinitialization not to use freed memory when
351 removing PMKSA entries
352 * fixed a memory leak in EAP-TTLS re-authentication
353 * reject WPA/WPA2 message 3/4 if it does not include any valid
355 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
356 if the driver does not support SIOCSIWAUTH
359 * driver_test: added better support for multiple APs and STAs by using
360 a directory with sockets that include MAC address for each device in
361 the name (driver_param=test_dir=/tmp/test)
362 * added support for EAP expanded type (vendor specific EAP methods)
363 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
364 option can be changed if needed
365 * wpa_cli/wpa_gui: skip non-socket files in control directory when
366 using UNIX domain sockets; this avoids selecting an incorrect
367 interface (e.g., a PID file could be in this directory, even though
368 use of this directory for something else than socket files is not
370 * fixed TLS library deinitialization after RSN pre-authentication not
371 to disable TLS library for normal authentication
372 * driver_wext: Remove null-termination from SSID length if the driver
373 used it; some Linux drivers do this and they were causing problems in
374 wpa_supplicant not finding matching configuration block. This change
375 would break a case where the SSID actually ends in '\0', but that is
376 not likely to happen in real use.
377 * fixed PMKSA cache processing not to trigger deauthentication if the
378 current PMKSA cache entry is replaced with a valid new entry
379 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
380 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
383 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
384 * added experimental STAKey handshake implementation for IEEE 802.11e
385 direct link setup (DLS); note: this is disabled by default in both
386 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
388 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
389 decrypt AT_ENCR_DATA attributes correctly
390 * fixed EAP-AKA to allow resynchronization within the same session
391 * made code closer to ANSI C89 standard to make it easier to port to
392 other C libraries and compilers
393 * started moving operating system or C library specific functions into
394 wrapper functions defined in os.h and implemented in os_*.c to make
396 * wpa_supplicant can now be built with Microsoft Visual C++
397 (e.g., with the freely available Toolkit 2003 version or Visual
398 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
399 example makefile for nmake
400 * added support for using Windows registry for command line parameters
401 (CONFIG_MAIN=main_winsvc) and configuration data
402 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
403 contents; this version can be run both as a Windows service and as a
404 normal application; 'wpasvc.exe app' to start as applicant,
405 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
406 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
408 * made it possible to link ndis_events.exe functionality into
409 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
410 * added better support for multiple control interface backends
411 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
412 * fixed PC/SC code to use correct length for GSM AUTH command buffer
413 and to not use pioRecvPci with SCardTransmit() calls; these were not
414 causing visible problems with pcsc-lite, but Windows Winscard.dll
415 refused the previously used parameters; this fixes EAP-SIM and
416 EAP-AKA authentication using SIM/USIM card under Windows
417 * added new event loop implementation for Windows using
418 WaitForMultipleObject() instead of select() in order to allow waiting
419 for non-socket objects; this can be selected with
420 CONFIG_ELOOP=eloop_win in .config
421 * added support for selecting l2_packet implementation in .config
422 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
423 winpcap, freebsd, none)
424 * added new l2_packet implementation for WinPcap
425 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
426 reduce latency in EAPOL receive processing from about 100 ms to about
428 * added support for EAP-FAST key derivation using other ciphers than
429 RC4-128-SHA for authentication and AES128-SHA for provisioning
430 * added support for configuring CA certificate as DER file and as a
432 * fixed private key configuration as configuration blob and added
433 support for using PKCS#12 as a blob
434 * tls_gnutls: added support for using PKCS#12 files; added support for
436 * added support for loading trusted CA certificates from Windows
437 certificate store: ca_cert="cert_store://<name>", where <name> is
438 likely CA (Intermediate CA certificates) or ROOT (root certificates)
439 * added C version of ndis_events.cpp and made it possible to build this
440 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
441 easily on cross-compilation builds
442 * added wpasvc.exe into Windows binary release; this is an alternative
443 version of wpa_supplicant.exe with configuration backend using
444 Windows registry and with the entry point designed to run as a
446 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
447 wpasvc.exe and removed this additional tool from the Windows binary
448 release since it is not needed anymore
449 * load winscard.dll functions dynamically when building with MinGW
450 since MinGW does not yet include winscard library
452 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
453 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
454 and WinPcap to receive frames sent to PAE group address
455 * disable EAP state machine when IEEE 802.1X authentication is not used
456 in order to get rid of bogus "EAP failed" messages
457 * fixed OpenSSL error reporting to go through all pending errors to
458 avoid confusing reports of old errors being reported at later point
460 * fixed configuration file updating to not write empty variables
461 (e.g., proto or key_mgmt) that the file parser would not accept
462 * fixed ADD_NETWORK ctrl_iface command to use the same default values
463 for variables as empty network definitions read from config file
465 * fixed EAP state machine to not discard EAP-Failure messages in many
466 cases (e.g., during TLS handshake)
467 * fixed a infinite loop in private key reading if the configured file
468 cannot be parsed successfully
469 * driver_madwifi: added support for madwifi-ng
470 * wpa_gui: do not display password/PSK field contents
471 * wpa_gui: added CA certificate configuration
472 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
473 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
474 the new AP is using different WPA/RSN IE
475 * use longer timeout for IEEE 802.11 association to avoid problems with
476 drivers that may take more than five second to associate
479 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
480 RSN IE, but WPA IE would match with wpa_supplicant configuration
481 * added support for named configuration blobs in order to avoid having
482 to use file system for external files (e.g., certificates);
483 variables can be set to "blob://<blob name>" instead of file path to
484 use a named blob; supported fields: pac_file, client_cert,
486 * fixed RSN pre-authentication (it was broken in the clean up of WPA
487 state machine interface in v0.4.5)
488 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
489 sure the driver configures broadcast decryption correctly
490 * added ca_path (and ca_path2) configuration variables that can be used
491 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
492 system-wide trusted CA list
493 * added support for starting wpa_supplicant without a configuration
494 file (-C argument must be used to set ctrl_interface parameter for
495 this case; in addition, -p argument can be used to provide
496 driver_param; these new arguments can also be used with a
497 configuration to override the values from the configuration)
498 * added global control interface that can be optionally used for adding
499 and removing network interfaces dynamically (-g command line argument
500 for both wpa_supplicant and wpa_cli) without having to restart
501 wpa_supplicant process
503 - try to save configuration whenever something is modified
504 - added WEP key configuration
505 - added possibility to edit the current network configuration
506 * driver_ndis: fixed driver polling not to increase frequency on each
507 received EAPOL frame due to incorrectly cancelled timeout
508 * added simple configuration file examples (in examples subdirectory)
509 * fixed driver_wext.c to filter wireless events based on ifindex to
510 avoid interfaces receiving events from other interfaces
511 * delay sending initial EAPOL-Start couple of seconds to speed up
512 authentication for the most common case of Authenticator starting
513 EAP authentication immediately after association
516 * added a workaround for clearing keys with ndiswrapper to allow
517 roaming from WPA enabled AP to plaintext one
518 * added docbook documentation (doc/docbook) that can be used to
519 generate, e.g., man pages
520 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
521 PF_PACKET in order to prepare for network devices that do not use
522 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
523 * use receipt of EAPOL-Key frame as a lower layer success indication
524 for EAP state machine to allow recovery from dropped EAP-Success
526 * cleaned up internal EAPOL frame processing by not including link
527 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
528 header is added only when transmitted the frame; this makes it easier
529 to use wpa_supplicant on link layers that use different header than
531 * updated EAP-PSK to use draft 9 by default since this can now be
532 tested with hostapd; removed support for draft 3, including
533 server_nai configuration option from network blocks
534 * driver_wired: add PAE address to the multicast address list in order
535 to be able to receive EAPOL frames with drivers that do not include
536 these multicast addresses by default
537 * driver_wext: add support for WE-19
538 * added support for multiple configuration backends (CONFIG_BACKEND
539 option); currently, only 'file' is supported (i.e., the format used
540 in wpa_supplicant.conf)
541 * added support for updating configuration ('wpa_cli save_config');
542 this is disabled by default and can be enabled with global
543 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
544 and wpa_gui to store the configuration changes in a permanent store
545 * added GET_NETWORK ctrl_iface command
546 (e.g., 'wpa_cli get_network 0 ssid')
549 * replaced OpenSSL patch for EAP-FAST support
550 (openssl-tls-extensions.patch) with a more generic and correct
551 patch (the new patch is not compatible with the previous one, so the
552 OpenSSL library will need to be patched with the new patch in order
553 to be able to build wpa_supplicant with EAP-FAST support)
554 * added support for using Windows certificate store (through CryptoAPI)
555 for client certificate and private key operations (EAP-TLS)
556 (see wpa_supplicant.conf for more information on how to configure
557 this with private_key)
558 * ported wpa_gui to Windows
559 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
560 built with the open source version of the Qt4 for Windows
561 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
562 with drivers that do not support WPA
563 * ndis_events: fixed Windows 2000 support
564 * added support for enabling/disabling networks from the list of all
565 configured networks ('wpa_cli enable_network <network id>' and
566 'wpa_cli disable_network <network id>')
567 * added support for adding and removing network from the current
568 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
569 <network id>'); added networks are disabled by default and they can
570 be enabled with enable_network command once the configuration is done
571 for the new network; note: configuration file is not yet updated, so
572 these new networks are lost when wpa_supplicant is restarted
573 * added support for setting network configuration parameters through
574 the control interface, for example:
575 wpa_cli set_network 0 ssid "\"my network\""
576 * fixed parsing of strings that include both " and # within double
577 quoted area (e.g., "start"#end")
578 * added EAP workaround for PEAP session resumption: allow outer,
579 i.e., not tunneled, EAP-Success to terminate session since; this can
580 be disabled with eap_workaround=0
581 (this was allowed for PEAPv1 before, but now it is also allowed for
582 PEAPv0 since at least one RADIUS authentication server seems to be
583 doing this for PEAPv0, too)
584 * wpa_gui: added preliminary support for adding new networks to the
585 wpa_supplicant configuration (double click on the scan results to
586 open network configuration)
589 * removed interface for external EAPOL/EAP supplicant (e.g.,
590 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
591 anymore and is unlikely to be used by anyone
592 * driver_ndis: fixed WinPcap 3.0 support
593 * fixed build with CONFIG_DNET_PCAP=y on Linux
594 * l2_packet: moved different implementations into separate files
598 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
599 (note: ipw2100-1.1.0 is likely to require an update to work with
601 * added support for using ap_scan=2 mode with multiple network blocks;
602 wpa_supplicant will go through the networks one by one until the
603 driver reports a successful association; this uses the same order for
604 networks as scan_ssid=1 scans, i.e., the priority field is ignored
605 and the network block order in the file is used instead
606 * fixed a potential issue in RSN pre-authentication ending up using
607 freed memory if pre-authentication times out
608 * added support for matching alternative subject name extensions of the
609 authentication server certificate; new configuration variables
610 altsubject_match and altsubject_match2
611 * driver_ndis: added support for IEEE 802.1X authentication with wired
613 * added support for querying private key password (EAP-TLS) through the
614 control interface (wpa_cli/wpa_gui) if one is not included in the
616 * driver_broadcom: fixed couple of memory leaks in scan result
618 * EAP-PAX is now registered as EAP type 46
619 * fixed EAP-PAX MAC calculation
620 * fixed EAP-PAX CK and ICK key derivation
621 * added support for using password with EAP-PAX (as an alternative to
622 entering key with eappsk); SHA-1 hash of the password will be used as
624 * added support for arbitrary driver interface parameters through the
625 configuration file with a new driver_param field; this adds a new
626 driver_ops function set_param()
627 * added possibility to override l2_packet module with driver interface
628 API (new send_eapol handler); this can be used to implement driver
629 specific TX/RX functions for EAPOL frames
630 * fixed ctrl_interface_group processing for the case where gid is
631 entered as a number, not group name
632 * driver_test: added support for testing hostapd with wpa_supplicant
633 by using test driver interface without any kernel drivers or network
637 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
638 packets to be encrypted; this was apparently broken by the changed
639 ioctl order in v0.4.0
640 * driver_madwifi: added preliminary support for compiling against 'BSD'
641 branch of madwifi CVS tree
642 * added support for EAP-MSCHAPv2 password retries within the same EAP
643 authentication session
644 * added support for password changes with EAP-MSCHAPv2 (used when the
645 password has expired)
646 * added support for reading additional certificates from PKCS#12 files
647 and adding them to the certificate chain
648 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
650 * fixed a possible double free in EAP-TTLS fast-reauthentication when
651 identity or password is entered through control interface
652 * display EAP Notification messages to user through control interface
653 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
654 * added GUI version of wpa_cli, wpa_gui; this is not build
655 automatically with 'make'; use 'make wpa_gui' to build (this requires
656 Qt development tools)
657 * added 'disconnect' command to control interface for setting
658 wpa_supplicant in state where it will not associate before
659 'reassociate' command has been used
660 * added support for selecting a network from the list of all configured
661 networks ('wpa_cli select_network <network id>'; this disabled all
662 other networks; to re-enable, 'wpa_cli select_network any')
663 * added support for getting scan results through control interface
664 * added EAP workaround for PEAPv1 session resumption: allow outer,
665 i.e., not tunneled, EAP-Success to terminate session since; this can
666 be disabled with eap_workaround=0
668 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
669 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
670 used to reduce the size of the wpa_supplicant considerably if
671 debugging code is not needed
672 * fixed EAPOL-Key validation to drop packets with invalid Key Data
673 Length; such frames could have crashed wpa_supplicant due to buffer
675 * added support for wired authentication (IEEE 802.1X on wired
676 Ethernet); driver interface 'wired'
677 * obsoleted set_wpa() handler in the driver interface API (it can be
678 replaced by moving enable/disable functionality into init()/deinit())
679 (calls to set_wpa() are still present for backwards compatibility,
680 but they may be removed in the future)
681 * driver_madwifi: fixed association in plaintext mode
682 * modified the EAP workaround that accepts EAP-Success with incorrect
683 Identifier to be even less strict about verification in order to
684 interoperate with some authentication servers
685 * added support for sending TLS alerts
686 * added support for 'any' SSID wildcard; if ssid is not configured or
687 is set to an empty string, any SSID will be accepted for non-WPA AP
688 * added support for asking PIN (for SIM) from frontends (e.g.,
689 wpa_cli); if a PIN is needed, but not included in the configuration
690 file, a control interface request is sent and EAP processing is
691 delayed until the PIN is available
692 * added support for using external devices (e.g., a smartcard) for
693 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
694 new wpa_supplicant.conf variables:
695 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
696 - network: engine, engine_id, key_id
697 * added experimental support for EAP-PAX
698 * added monitor mode for wpa_cli (-a<path to a program to run>) that
699 allows external commands (e.g., shell scripts) to be run based on
700 wpa_supplicant events, e.g., when authentication has been completed
701 and data connection is ready; other related wpa_cli arguments:
702 -B (run in background), -P (write PID file); wpa_supplicant has a new
703 command line argument (-W) that can be used to make it wait until a
704 control interface command is received in order to avoid missing
706 * added support for opportunistic WPA2 PMKSA key caching (disabled by
707 default, can be enabled with proactive_key_caching=1)
708 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
709 Authenticator rejects PMKSA caching attempt and the driver is not
710 using assoc_info events
711 * added -P<pid file> argument for wpa_supplicant to write the current
712 process id into a file
714 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
715 * added new phase1 option parameter, include_tls_length=1, to force
716 wpa_supplicant to add TLS Message Length field to all TLS messages
717 even if the packet is not fragmented; this may be needed with some
718 authentication servers
719 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
720 using drivers that take care of AP selection (e.g., when using
722 * fixed reprocessing of pending request after ctrl_iface requests for
723 identity/password/otp
724 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
725 EAP-PEAP and EAP-TTLS
726 * all drivers using driver_wext: set interface up and select Managed
727 mode when starting wpa_supplicant; set interface down when exiting
728 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
729 ipw2100 and ipw2200; please note that this also changed the
730 configuration variable in .config to CONFIG_DRIVER_IPW
733 * fixed a busy loop introduced in v0.3.5 for scan result processing
734 when no matching AP is found
737 * added a workaround for an interoperability issue with a Cisco AP
739 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
740 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
741 retransmission of dropped frames)
742 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
743 (e.g., segfault when processing EAPOL-Key frames)
744 * fixed EAP workaround and fast reauthentication configuration for
745 RSN pre-authentication; previously these were disabled and
746 pre-authentication would fail if the used authentication server
747 requires EAP workarounds
748 * added support for blacklisting APs that fail or timeout
749 authentication in ap_scan=1 mode so that all APs are tried in cases
750 where the ones with strongest signal level are failing authentication
751 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
752 authentication attempt
753 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
754 in the previous authentication (previously, only Phase 1 success was
758 * added preliminary support for IBSS (ad-hoc) mode configuration
759 (mode=1 in network block); this included a new key_mgmt mode
760 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
761 key management; see wpa_supplicant.conf for more details and an
762 example on how to configure this (note: this is currently implemented
763 only for driver_hostapd.c, but the changes should be trivial to add
764 in associate() handler for other drivers, too (assuming the driver
766 * added preliminary port for native Windows (i.e., no cygwin) using
770 * added optional support for GNU Readline and History Libraries for
771 wpa_cli (CONFIG_READLINE)
772 * cleaned up EAP state machine <-> method interface and number of
773 small problems with error case processing not terminating on
774 EAP-Failure but waiting for timeout
775 * added couple of workarounds for interoperability issues with a
776 Cisco AP when using WPA2
777 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
778 Note: This requires a patch for openssl to add support for TLS
779 extensions and number of workarounds for operations without
780 certificates. Proof of concept type of experimental patch is
781 included in openssl-tls-extensions.patch.
784 * fixed private key loading for cases where passphrase is not set
785 * fixed Windows/cygwin L2 packet handler freeing; previous version
786 could cause a segfault when RSN pre-authentication was completed
787 * added support for PMKSA caching with drivers that generate RSN IEs
788 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
789 but similar code can be easily added to driver_ndiswrapper.c once
790 ndiswrapper gets full support for RSN PMKSA caching
791 * improved recovery from PMKID mismatches by requesting full EAP
792 authentication in case of failed PMKSA caching attempt
793 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
794 (this requires that ndis_events is ran while wpa_supplicant is
796 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
797 * added support for driver interfaces to replace the interface name
798 based on driver/OS specific mapping, e.g., in case of driver_ndis,
799 this allows the beginning of the adapter description to be used as
801 * added support for CR+LF (Windows-style) line ends in configuration
803 * driver_ndis: enable radio before starting scanning, disable radio
805 * modified association event handler to set portEnabled = FALSE before
806 clearing port Valid in order to reset EAP state machine and avoid
807 problems with new authentication getting ignored because of state
808 machines ending up in AUTHENTICATED/SUCCESS state based on old
810 * added support for driver events to add PMKID candidates in order to
811 allow drivers to give priority to most likely roaming candidates
812 * driver_hostap: moved PrivacyInvoked configuration to associate()
813 function so that this will not be set for plaintext connections
814 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
815 interface can distinguish plaintext and IEEE 802.1X (no WPA)
817 * fixed static WEP key configuration to use broadcast/default type for
818 all keys (previously, the default TX key was configured as pairwise/
820 * driver_ndis: added legacy WPA capability detection for non-WPA2
822 * added support for setting static WEP keys for IEEE 802.1X without
823 dynamic WEP keying (eapol_flags=0)
826 * added support for reading PKCS#12 (PFX) files (as a replacement for
827 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
828 * fixed compilation with CONFIG_PCSC=y
829 * added new ap_scan mode, ap_scan=2, for drivers that take care of
830 association, but need to be configured with security policy and SSID,
831 e.g., ndiswrapper and NDIS driver; this mode should allow such
832 drivers to work with hidden SSIDs and optimized roaming; when
833 ap_scan=2 is used, only the first network block in the configuration
834 file is used and this configuration should have explicit security
835 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
836 group, proto variables
837 * added experimental port of wpa_supplicant for Windows
838 - driver_ndis.c driver interface (NDIS OIDs)
839 - currently, this requires cygwin and WinPcap
840 - small utility, win_if_list, can be used to get interface name
841 * control interface can now be removed at build time; add
842 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
843 * optional Xsupplicant interface can now be removed at build time;
844 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
845 * added auth_alg to driver interface associate() parameters to make it
846 easier for drivers to configure authentication algorithm as part of
849 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
850 * driver_broadcom: added new driver interface for Broadcom wl.o driver
851 (a generic driver for Broadcom IEEE 802.11a/g cards)
852 * wpa_cli: fixed parsing of -p <path> command line argument
853 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
854 ACK, not tunneled EAP-Success (of which only the first byte was
855 actually send due to a bug in previous code); this seems to
856 interoperate with most RADIUS servers that implements PEAPv1
857 * PEAPv1: added support for terminating PEAP authentication on tunneled
858 EAP-Success message; this can be configured by adding
859 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
860 (some RADIUS servers require this whereas others require a tunneled
862 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
863 the old label for key derivation; previously, the default was 1,
864 but it looks like most existing PEAPv1 implementations use the old
865 label which is thus more suitable default option
866 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
867 * fixed parsing of wep_tx_keyidx
868 * added support for configuring list of allowed Phase 2 EAP types
869 (for both EAP-PEAP and EAP-TTLS) instead of only one type
870 * added support for configuring IEEE 802.11 authentication algorithm
871 (auth_alg; mainly for using Shared Key authentication with static
873 * added support for EAP-AKA (with UMTS SIM)
874 * fixed couple of errors in PCSC handling that could have caused
875 random-looking errors for EAP-SIM
876 * added support for EAP-SIM pseudonyms and fast re-authentication
877 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
879 * added support for EAP-SIM with two challanges
880 (phase1="sim_min_num_chal=3" can be used to require three challenges)
881 * added support for configuring DH/DSA parameters for an ephemeral DH
882 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
883 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
884 and optional DH key exchange to achieve forward secracy with RSA keys
885 * added support for matching subject of the authentication server
886 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
887 configuration variables subject_match and subject_match2
888 * changed SSID configuration in driver_wext.c (used by many driver
889 interfaces) to use ssid_len+1 as the length for SSID since some Linux
891 * fixed couple of unaligned reads in scan result parsing to fix WPA
892 connection on some platforms (e.g., ARM)
893 * added driver interface for Intel ipw2100 driver
894 * added support for LEAP with WPA
895 * added support for larger scan results report (old limit was 4 kB of
896 data, i.e., about 35 or so APs) when using Linux wireless extensions
898 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
899 only if there is a PMKSA cache entry for the current AP
900 * fixed error handling for case where reading of scan results fails:
901 must schedule a new scan or wpa_supplicant will remain waiting
903 * changed debug output to remove shared password/key material by
904 default; all key information can be included with -K command line
905 argument to match the previous behavior
906 * added support for timestamping debug log messages (disabled by
907 default, can be enabled with -t command line argument)
908 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
909 if keys are not configured to be used; this fixes IEEE 802.1X mode
910 with drivers that use this information to configure whether Privacy
911 bit can be in Beacon frames (e.g., ndiswrapper)
912 * avoid clearing driver keys if no keys have been configured since last
913 key clear request; this seems to improve reliability of group key
914 handshake for ndiswrapper & NDIS driver which seems to be suffering
915 of some kind of timing issue when the keys are cleared again after
917 * changed driver interface API:
918 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
919 version is being used (now, this is set to 2; previously, it was
921 - pass pointer to private data structure to all calls
922 - the new API is not backwards compatible; all in-tree driver
923 interfaces has been converted to the new API
924 * added support for controlling multiple interfaces (radios) per
925 wpa_supplicant process; each interface needs to be listed on the
926 command line (-c, -i, -D arguments) with -N as a separator
927 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
928 * added a workaround for EAP servers that incorrectly use same Id for
929 sequential EAP packets
930 * changed libpcap/libdnet configuration to use .config variable,
931 CONFIG_DNET_PCAP, instead of requiring Makefile modification
932 * improved downgrade attack detection in IE verification of msg 3/4:
933 verify both WPA and RSN IEs, if present, not only the selected one;
934 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
935 Probe Response frame, and RSN is enabled in wpa_supplicant
937 * fixed WPA msg 3/4 processing to allow Key Data field contain other
938 IEs than just one WPA IE
939 * added support for FreeBSD and driver interface for the BSD net80211
940 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
941 required kernel mods have not yet been committed
942 * made EAP workarounds configurable; enabled by default, can be
943 disabled with network block option eap_workaround=0
945 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
946 * resolved couple of interoperability issues with EAP-PEAPv1 and
947 Phase 2 (inner EAP) fragment reassembly
948 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
949 AP is using non-zero key index for the unicast key and key index zero
950 for the broadcast key
951 * driver_hostap: fixed IEEE 802.1X WEP key updates and
952 re-authentication by allowing unencrypted EAPOL frames when not using
954 * added a new driver interface, 'wext', which uses only standard,
955 driver independent functionality in Linux wireless extensions;
956 currently, this can be used only for non-WPA IEEE 802.1X mode, but
957 eventually, this is to be extended to support full WPA/WPA2 once
958 Linux wireless extensions get support for this
959 * added support for mode in which the driver is responsible for AP
960 scanning and selection; this is disabled by default and can be
961 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
962 this mode can be used, e.g., with generic 'wext' driver interface to
963 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
964 supporting wireless extensions.
965 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
966 operation with an AP that does not include SSID in the Beacon frames)
967 * added support for new EAP authentication methods:
968 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
969 * added support for asking one-time-passwords from frontends (e.g.,
970 wpa_cli); this 'otp' command works otherwise like 'password' command,
971 but the password is used only once and the frontend will be asked for
972 a new password whenever a request from authenticator requires a
973 password; this can be used with both EAP-OTP and EAP-GTC
974 * changed wpa_cli to automatically re-establish connection so that it
975 does not need to be re-started when wpa_supplicant is terminated and
977 * improved user data (identity/password/otp) requests through
978 frontends: process pending EAPOL packets after getting new
979 information so that full authentication does not need to be
980 restarted; in addition, send pending requests again whenever a new
982 * changed control frontends to use a new directory for socket files to
983 make it easier for wpa_cli to automatically select between interfaces
984 and to provide access control for the control interface;
985 wpa_supplicant.conf: ctrl_interface is now a path
986 (/var/run/wpa_supplicant is the recommended path) and
987 ctrl_interface_group can be used to select which group gets access to
988 the control interface;
989 wpa_cli: by default, try to connect to the first interface available
990 in /var/run/wpa_supplicant; this path can be overriden with -p option
991 and an interface can be selected with -i option (i.e., in most common
992 cases, wpa_cli does not need to get any arguments)
993 * added support for LEAP
994 * added driver interface for Linux ndiswrapper
995 * added priority option for network blocks in the configuration file;
996 this allows networks to be grouped based on priority (the scan
997 results are searched for matches with network blocks in this order)
1000 * sort scan results to improve AP selection
1001 * fixed control interface socket removal for some error cases
1002 * improved scan requesting and authentication timeout
1003 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1005 * PEAP version can now be forced with phase1="peapver=<ver>"
1006 (mostly for testing; by default, the highest version supported by
1007 both the Supplicant and Authentication Server is selected
1009 * added support for madwifi driver (Atheros ar521x)
1010 * added a workaround for cases where AP sets Install Tx/Rx bit for
1011 WPA Group Key messages when pairwise keys are used (without this,
1012 the Group Key would be used for Tx and the AP would drop frames
1014 * added GSM SIM/USIM interface for GSM authentication algorithm for
1015 EAP-SIM; this requires pcsc-lite
1016 * added support for ATMEL AT76C5XXx driver
1017 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1018 does not include key data in the EAPOL-Key frame (i.e., part of
1019 EAP keying material is used as data encryption key)
1020 * added support for using plaintext and static WEP networks
1024 * added support for new EAP authentication methods:
1025 EAP-TTLS/EAP-MD5-Challenge
1027 EAP-TTLS/EAP-MSCHAPv2
1035 EAP-PEAP/MD5-Challenge
1037 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1038 * added support for anonymous identity (to be used when identity is
1039 sent in plaintext; real identity will be used within TLS protected
1040 tunnel (e.g., with EAP-TTLS)
1041 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1042 * added support for requesting identity and password information using
1043 control interface; in other words, the password for EAP-PEAP or
1044 EAP-TTLS does not need to be included in the configuration file since
1045 a frontand (e.g., wpa_cli) can ask it from the user
1046 * improved RSN pre-authentication to use a candidate list and process
1047 all candidates from each scan; not only one per scan
1048 * fixed RSN IE and WPA IE capabilities field parsing
1049 * ignore Tx bit in GTK IE when Pairwise keys are used
1050 * avoid making new scan requests during IEEE 802.1X negotiation
1051 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1052 with TLS support (this replaces the included implementation with
1053 library code to save about 8 kB since the library code is needed
1055 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1056 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1059 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1061 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1062 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1063 - EAP-MD5 (cannot be used with WPA-RADIUS)
1064 [draft-ietf-eap-rfc2284bis-09.txt]
1065 - EAP-TLS [RFC 2716]
1066 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1067 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1068 [draft-kamath-pppext-eap-mschapv2-00.txt]
1069 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1070 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1071 - new configuration file options: eap, identity, password, ca_cert,
1072 client_cert, privatekey, private_key_passwd
1073 - Xsupplicant is not required anymore, but it can be used by
1074 disabling the internal IEEE 802.1X Supplicant with -e command line
1076 - this code is not included in the default build; Makefile need to
1077 be edited for this (uncomment lines for selected functionality)
1078 - EAP-TLS and EAP-PEAP require openssl libraries
1079 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1080 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1081 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1082 EAPOL-Key frames instead of WPA key handshakes)
1083 * added support for IEEE 802.11i/RSN (WPA2)
1084 - improved PTK Key Handshake
1085 - PMKSA caching, pre-authentication
1086 * fixed wpa_supplicant to ignore possible extra data after WPA
1087 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1088 TPTK' error from message 3 of 4-Way Handshake in case the AP
1089 includes extra data after the EAPOL-Key)
1090 * added interface for external programs (frontends) to control
1092 - CLI example (wpa_cli) with interactive mode and command line
1094 - replaced SIGUSR1 status/statistics with the new control interface
1095 * made some feature compile time configurable
1096 - .config file for make
1097 - driver interfaces (hostap, hermes, ..)
1098 - EAPOL/EAP functions
1101 * Initial version of wpa_supplicant
