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
8 * removed 'nai' and 'eappsk' network configuration variables that were
9 previously used for configuring user identity and key for EAP-PSK,
10 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
11 replacement for 'nai' (if old configuration used a separate
12 'identity' value, that would now be configured as
13 'anonymous_identity'). 'password' field is now used as the
14 replacement for 'eappsk' (it can also be set using hexstring to
15 present random binary data)
16 * removed '-w' command line parameter (wait for interface to be added,
17 if needed); cleaner way of handling this functionality is to use an
18 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
19 when an interface is added
20 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
21 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
22 indicating when new scan results become available
23 * added new ctrl_iface command, BSS, to allow scan results to be
24 fetched without hitting the message size limits (this command
25 can be used to iterate through the scan results one BSS at the time)
26 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
27 attributes in EAP-SIM Start/Response when using fast reauthentication
28 * fixed EAPOL not to end up in infinite loop when processing dynamic
29 WEP keys with IEEE 802.1X
30 * fixed problems in getting NDIS events from WMI on Windows 2000
33 * added support for Makefile builds to include debug-log-to-a-file
34 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
35 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
36 lengths properly to avoid potential crash caused by invalid messages
37 * added data structure for storing allocated buffers (struct wpabuf);
38 this does not affect wpa_supplicant usage, but many of the APIs
39 changed and various interfaces (e.g., EAP) is not compatible with old
41 * added support for protecting EAP-AKA/Identity messages with
42 AT_CHECKCODE (optional feature in RFC 4187)
43 * added support for protected result indication with AT_RESULT_IND for
44 EAP-SIM and EAP-AKA (phase1="result_ind=1")
45 * added driver_wext workaround for race condition between scanning and
46 association with drivers that take very long time to scan all
47 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
48 using a longer hardcoded timeout for the scan if the driver supports
49 notifications for scan completion (SIOCGIWSCAN event); this helps,
50 e.g., in cases where wpa_supplicant and madwifi driver ended up in
51 loop where the driver did not even try to associate
52 * stop EAPOL timer tick when no timers are in use in order to reduce
53 power consumption (no need to wake up the process once per second)
55 * added support for privilege separation (run only minimal part of
56 wpa_supplicant functionality as root and rest as unprivileged,
57 non-root process); see 'Privilege separation' in README for details;
58 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
60 * changed scan results data structure to include all information
61 elements to make it easier to support new IEs; old get_scan_result()
62 driver_ops is still supported for backwards compatibility (results
63 are converted internally to the new format), but all drivers should
64 start using the new get_scan_results2() to make them more likely to
65 work with new features
66 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
67 application, i.e., it does not require Qt3Support anymore; Windows
68 binary of wpa_gui.exe is now from this directory and only requires
69 QtCore4.dll and QtGui4.dll libraries
70 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
71 available as a separate package to make wpa_gui installation easier:
72 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
73 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
74 only shared key/password authentication is supported in this version
77 * added support for configuring password as NtPasswordHash
78 (16-byte MD4 hash of password) in hash:<32 hex digits> format
79 * added support for fallback from abbreviated TLS handshake to
80 full handshake when using EAP-FAST (e.g., due to an expired
82 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
83 draft (draft-ietf-emu-eap-gpsk-07.txt)
84 * added support for drivers that take care of RSN 4-way handshake
85 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
86 WPA_ALG_PMK in set_key)
87 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
88 .config); this version supports only ap_scan=2 mode and allow the
89 driver to take care of the 4-way handshake
90 * fixed a buffer overflow in parsing TSF from scan results when using
91 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
93 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
94 * fixed an integer overflow issue in the ASN.1 parser used by the
95 (experimental) internal TLS implementation to avoid a potential
97 * fixed a race condition with -W option (wait for a control interface
98 monitor before starting) that could have caused the first messages to
100 * added support for processing TNCC-TNCS-Messages to report
101 recommendation (allow/none/isolate) when using TNC [Bug 243]
104 * added network configuration parameter 'frequency' for setting
105 initial channel for IBSS (adhoc) networks
106 * added experimental IEEE 802.11r/D6.0 support
107 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
108 * updated EAP-PSK to use the IANA-allocated EAP type 47
109 * fixed EAP-PAX key derivation
110 * fixed EAP-PSK bit ordering of the Flags field
111 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
112 tunnelled identity request (previously, the identifier from the outer
113 method was used, not the tunnelled identifier which could be
115 * added support for fragmentation of outer TLS packets during Phase 2
116 of EAP-PEAP/TTLS/FAST
117 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
118 * added support for EAP-FAST authentication with inner methods that
119 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
120 for PAC provisioning)
121 * added support for authenticated EAP-FAST provisioning
122 * added support for configuring maximum number of EAP-FAST PACs to
123 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
124 * added support for storing EAP-FAST PACs in binary format
125 (fast_pac_format=binary in phase1 string)
126 * fixed dbus ctrl_iface to validate message interface before
127 dispatching to avoid a possible segfault [Bug 190]
128 * fixed PeerKey key derivation to use the correct PRF label
129 * updated Windows binary build to link against OpenSSL 0.9.8d and
130 added support for EAP-FAST
131 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
132 draft (draft-ietf-emu-eap-gpsk-04.txt)
133 * fixed EAP-AKA Notification processing to allow Notification to be
134 processed after AKA Challenge response has been sent
135 * updated to use IEEE 802.11w/D2.0 for management frame protection
137 * fixed EAP-TTLS implementation not to crash on use of freed memory
138 if TLS library initialization fails
139 * added support for EAP-TNC (Trusted Network Connect)
140 (this version implements the EAP-TNC method and EAP-TTLS changes
141 needed to run two methods in sequence (IF-T) and the IF-IMC and
142 IF-TNCCS interfaces from TNCC)
145 * added experimental, integrated TLSv1 client implementation with the
146 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
147 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
148 .config); this can be useful, e.g., if the target system does not
149 have a suitable TLS library and a minimal code size is required
150 (total size of this internal TLS/crypto code is bit under 50 kB on
151 x86 and the crypto code is shared by rest of the supplicant so some
152 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
153 * removed STAKey handshake since PeerKey handshake has replaced it in
154 IEEE 802.11ma and there are no known deployments of STAKey
155 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
156 draft (draft-ietf-emu-eap-gpsk-01.txt)
157 * added preliminary implementation of IEEE 802.11w/D1.0 (management
159 (Note: this requires driver support to work properly.)
160 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
161 * fixed Windows named pipes ctrl_iface to not stop listening for
162 commands if client program opens a named pipe and closes it
163 immediately without sending a command
164 * fixed USIM PIN status determination for the case that PIN is not
165 needed (this allows EAP-AKA to be used with USIM cards that do not
167 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
168 be used with cards that do not support file selection based on
170 * added support for matching the subjectAltName of the authentication
171 server certificate against multiple name components (e.g.,
172 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
173 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
174 affects IEEE 802.1X with dynamic WEP keys)
175 * changed ctrl_iface network configuration 'get' operations to not
176 return password/key material; if these fields are requested, "*"
177 will be returned if the password/key is set, but the value of the
178 parameter is not exposed
181 * added support for building Windows version with UNICODE defined
182 (wide-char functions)
183 * driver_ndis: fixed static WEP configuration to avoid race condition
184 issues with some NDIS drivers between association and setting WEP
186 * driver_ndis: added validation for IELength value in scan results to
187 avoid crashes when using buggy NDIS drivers [Bug 165]
188 * fixed Release|Win32 target in the Visual Studio project files
189 (previously, only Debug|Win32 target was set properly)
190 * changed control interface API call wpa_ctrl_pending() to allow it to
191 return -1 on error (e.g., connection lost); control interface clients
192 will need to make sure that they verify that the value is indeed >0
193 when determining whether there are pending messages
194 * added an alternative control interface backend for Windows targets:
195 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
196 control interface mechanism for Windows builds (previously, UDP to
198 * changed ctrl_interface configuration for UNIX domain sockets:
199 - deprecated ctrl_interface_group variable (it may be removed in
201 - allow both directory and group be configured with ctrl_interface
202 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
203 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
204 case when group is not changed
205 * added support for controlling more than one interface per process in
207 * added a workaround for a case where the AP is using unknown address
208 (e.g., MAC address of the wired interface) as the source address for
209 EAPOL-Key frames; previously, that source address was used as the
210 destination for EAPOL-Key frames and in key derivation; now, BSSID is
211 used even if the source address does not match with it
212 (this resolves an interoperability issue with Thomson SpeedTouch 580)
213 * added a workaround for UDP-based control interface (which was used in
214 Windows builds before this release) to prevent packets with forged
215 addresses from being accepted as local control requests
216 * removed ndis_events.cpp and possibility of using external
217 ndis_events.exe; C version (ndis_events.c) is fully functional and
218 there is no desire to maintain two separate versions of this
220 * ndis_events: Changed NDIS event notification design to use WMI to
221 learn the adapter description through Win32_PnPEntity class; this
222 should fix some cases where the adapter name was not recognized
223 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
225 * fixed selection of the first network in ap_scan=2 mode; previously,
226 wpa_supplicant could get stuck in SCANNING state when only the first
227 network for enabled (e.g., after 'wpa_cli select_network 0')
228 * winsvc: added support for configuring ctrl_interface parameters in
229 registry (ctrl_interface string value in
230 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
231 required to enable control interface (previously, this was hardcoded
233 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
234 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
237 * fixed build with CONFIG_STAKEY=y [Bug 143]
238 * added support for doing MLME (IEEE 802.11 management frame
239 processing) in wpa_supplicant when using Devicescape IEEE 802.11
240 stack (wireless-dev.git tree)
241 * added a new network block configuration option, fragment_size, to
242 configure the maximum EAP fragment size
243 * driver_ndis: Disable WZC automatically for the selected interface to
244 avoid conflicts with two programs trying to control the radio; WZC
245 will be re-enabled (if it was enabled originally) when wpa_supplicant
247 * added an experimental TLSv1 client implementation
248 (CONFIG_TLS=internal) that can be used instead of an external TLS
249 library, e.g., to reduce total size requirement on systems that do
250 not include any TLS library by default (this is not yet complete;
251 basic functionality is there, but certificate validation is not yet
253 * added PeerKey handshake implementation for IEEE 802.11e
254 direct link setup (DLS) to replace STAKey handshake
255 * fixed WPA PSK update through ctrl_iface for the case where the old
256 PSK was derived from an ASCII passphrase and the new PSK is set as
257 a raw PSK (hex string)
258 * added new configuration option for identifying which network block
259 was used (id_str in wpa_supplicant.conf; included on
260 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
261 variable in wpa_cli action scripts; in addition WPA_ID variable is
262 set to the current unique identifier that wpa_supplicant assigned
263 automatically for the network and that can be used with
264 GET_NETWORK/SET_NETWORK ctrl_iface commands)
265 * wpa_cli action script is now called only when the connect/disconnect
266 status changes or when associating with a different network
267 * fixed configuration parser not to remove CCMP from group cipher list
268 if WPA-None (adhoc) is used (pairwise=NONE in that case)
269 * fixed integrated NDIS events processing not to hang the process due
270 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
271 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
272 draft-clancy-emu-eap-shared-secret-00.txt)
273 * added Microsoft Visual Studio 2005 solution and project files for
274 build wpa_supplicant for Windows (see vs2005 subdirectory)
275 * eloop_win: fixed unregistration of Windows events
276 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
277 at the end of RSN pre-authentication and added unregistration of
278 a Windows event to avoid getting eloop_win stuck with an invalid
280 * driver_ndis: added support for selecting AP based on BSSID
281 * added new environmental variable for wpa_cli action scripts:
282 WPA_CTRL_DIR is the current control interface directory
283 * driver_ndis: added support for using NDISUIO instead of WinPcap for
284 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
285 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
286 wpa_supplicant without requiring WinPcap; note that using NDISUIO
287 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
288 only one application to open the device
289 * changed NDIS driver naming to only include device GUID, e.g.,
290 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
291 specific \Device\NPF_ prefix before the GUID; the prefix is still
292 allowed for backwards compatibility, but it is not required anymore
293 when specifying the interface
294 * driver_ndis: re-initialize driver interface is the adapter is removed
295 and re-inserted [Bug 159]
296 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
297 big endian hosts [Bug 146]
300 * fixed EAP-GTC response to include correct user identity when run as
301 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
302 * driver_ndis: Fixed encryption mode configuration for unencrypted
303 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
304 refused to associate with open networks) [Bug 106]
305 * driver_ndis: use BSSID OID polling to detect when IBSS network is
306 formed even when ndis_events code is included since some NDIS drivers
307 do not generate media connect events in IBSS mode
308 * config_winreg: allow global ctrl_interface parameter to be configured
310 * config_winreg: added support for saving configuration data into
312 * added support for controlling network device operational state
313 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
314 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
315 that can use this information)
316 * driver_wext: added support for WE-21 change to SSID configuration
317 * driver_wext: fixed privacy configuration for static WEP keys mode
319 * added an optional driver_ops callback for MLME-SETPROTECTION.request
321 * added support for EAP-SAKE (no EAP method number allocated yet, so
322 this is using the same experimental type 255 as EAP-PSK)
323 * added support for dynamically loading EAP methods (.so files) instead
324 of requiring them to be statically linked in; this is disabled by
325 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
329 * do not try to use USIM APDUs when initializing PC/SC for SIM card
330 access for a network that has not enabled EAP-AKA
331 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
332 v0.5.1 due to the new support for expanded EAP types)
333 * added support for generating EAP Expanded Nak
334 * try to fetch scan results once before requesting new scan when
335 starting up in ap_scan=1 mode (this can speed up initial association
336 a lot with, e.g., madwifi-ng driver)
337 * added support for receiving EAPOL frames from a Linux bridge
338 interface (-bbr0 on command line)
339 * fixed EAPOL re-authentication for sessions that used PMKSA caching
340 * changed EAP method registration to use a dynamic list of methods
341 instead of a static list generated at build time
342 * fixed PMKSA cache deinitialization not to use freed memory when
343 removing PMKSA entries
344 * fixed a memory leak in EAP-TTLS re-authentication
345 * reject WPA/WPA2 message 3/4 if it does not include any valid
347 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
348 if the driver does not support SIOCSIWAUTH
351 * driver_test: added better support for multiple APs and STAs by using
352 a directory with sockets that include MAC address for each device in
353 the name (driver_param=test_dir=/tmp/test)
354 * added support for EAP expanded type (vendor specific EAP methods)
355 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
356 option can be changed if needed
357 * wpa_cli/wpa_gui: skip non-socket files in control directory when
358 using UNIX domain sockets; this avoids selecting an incorrect
359 interface (e.g., a PID file could be in this directory, even though
360 use of this directory for something else than socket files is not
362 * fixed TLS library deinitialization after RSN pre-authentication not
363 to disable TLS library for normal authentication
364 * driver_wext: Remove null-termination from SSID length if the driver
365 used it; some Linux drivers do this and they were causing problems in
366 wpa_supplicant not finding matching configuration block. This change
367 would break a case where the SSID actually ends in '\0', but that is
368 not likely to happen in real use.
369 * fixed PMKSA cache processing not to trigger deauthentication if the
370 current PMKSA cache entry is replaced with a valid new entry
371 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
372 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
375 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
376 * added experimental STAKey handshake implementation for IEEE 802.11e
377 direct link setup (DLS); note: this is disabled by default in both
378 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
380 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
381 decrypt AT_ENCR_DATA attributes correctly
382 * fixed EAP-AKA to allow resynchronization within the same session
383 * made code closer to ANSI C89 standard to make it easier to port to
384 other C libraries and compilers
385 * started moving operating system or C library specific functions into
386 wrapper functions defined in os.h and implemented in os_*.c to make
388 * wpa_supplicant can now be built with Microsoft Visual C++
389 (e.g., with the freely available Toolkit 2003 version or Visual
390 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
391 example makefile for nmake
392 * added support for using Windows registry for command line parameters
393 (CONFIG_MAIN=main_winsvc) and configuration data
394 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
395 contents; this version can be run both as a Windows service and as a
396 normal application; 'wpasvc.exe app' to start as applicant,
397 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
398 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
400 * made it possible to link ndis_events.exe functionality into
401 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
402 * added better support for multiple control interface backends
403 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
404 * fixed PC/SC code to use correct length for GSM AUTH command buffer
405 and to not use pioRecvPci with SCardTransmit() calls; these were not
406 causing visible problems with pcsc-lite, but Windows Winscard.dll
407 refused the previously used parameters; this fixes EAP-SIM and
408 EAP-AKA authentication using SIM/USIM card under Windows
409 * added new event loop implementation for Windows using
410 WaitForMultipleObject() instead of select() in order to allow waiting
411 for non-socket objects; this can be selected with
412 CONFIG_ELOOP=eloop_win in .config
413 * added support for selecting l2_packet implementation in .config
414 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
415 winpcap, freebsd, none)
416 * added new l2_packet implementation for WinPcap
417 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
418 reduce latency in EAPOL receive processing from about 100 ms to about
420 * added support for EAP-FAST key derivation using other ciphers than
421 RC4-128-SHA for authentication and AES128-SHA for provisioning
422 * added support for configuring CA certificate as DER file and as a
424 * fixed private key configuration as configuration blob and added
425 support for using PKCS#12 as a blob
426 * tls_gnutls: added support for using PKCS#12 files; added support for
428 * added support for loading trusted CA certificates from Windows
429 certificate store: ca_cert="cert_store://<name>", where <name> is
430 likely CA (Intermediate CA certificates) or ROOT (root certificates)
431 * added C version of ndis_events.cpp and made it possible to build this
432 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
433 easily on cross-compilation builds
434 * added wpasvc.exe into Windows binary release; this is an alternative
435 version of wpa_supplicant.exe with configuration backend using
436 Windows registry and with the entry point designed to run as a
438 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
439 wpasvc.exe and removed this additional tool from the Windows binary
440 release since it is not needed anymore
441 * load winscard.dll functions dynamically when building with MinGW
442 since MinGW does not yet include winscard library
444 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
445 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
446 and WinPcap to receive frames sent to PAE group address
447 * disable EAP state machine when IEEE 802.1X authentication is not used
448 in order to get rid of bogus "EAP failed" messages
449 * fixed OpenSSL error reporting to go through all pending errors to
450 avoid confusing reports of old errors being reported at later point
452 * fixed configuration file updating to not write empty variables
453 (e.g., proto or key_mgmt) that the file parser would not accept
454 * fixed ADD_NETWORK ctrl_iface command to use the same default values
455 for variables as empty network definitions read from config file
457 * fixed EAP state machine to not discard EAP-Failure messages in many
458 cases (e.g., during TLS handshake)
459 * fixed a infinite loop in private key reading if the configured file
460 cannot be parsed successfully
461 * driver_madwifi: added support for madwifi-ng
462 * wpa_gui: do not display password/PSK field contents
463 * wpa_gui: added CA certificate configuration
464 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
465 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
466 the new AP is using different WPA/RSN IE
467 * use longer timeout for IEEE 802.11 association to avoid problems with
468 drivers that may take more than five second to associate
471 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
472 RSN IE, but WPA IE would match with wpa_supplicant configuration
473 * added support for named configuration blobs in order to avoid having
474 to use file system for external files (e.g., certificates);
475 variables can be set to "blob://<blob name>" instead of file path to
476 use a named blob; supported fields: pac_file, client_cert,
478 * fixed RSN pre-authentication (it was broken in the clean up of WPA
479 state machine interface in v0.4.5)
480 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
481 sure the driver configures broadcast decryption correctly
482 * added ca_path (and ca_path2) configuration variables that can be used
483 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
484 system-wide trusted CA list
485 * added support for starting wpa_supplicant without a configuration
486 file (-C argument must be used to set ctrl_interface parameter for
487 this case; in addition, -p argument can be used to provide
488 driver_param; these new arguments can also be used with a
489 configuration to override the values from the configuration)
490 * added global control interface that can be optionally used for adding
491 and removing network interfaces dynamically (-g command line argument
492 for both wpa_supplicant and wpa_cli) without having to restart
493 wpa_supplicant process
495 - try to save configuration whenever something is modified
496 - added WEP key configuration
497 - added possibility to edit the current network configuration
498 * driver_ndis: fixed driver polling not to increase frequency on each
499 received EAPOL frame due to incorrectly cancelled timeout
500 * added simple configuration file examples (in examples subdirectory)
501 * fixed driver_wext.c to filter wireless events based on ifindex to
502 avoid interfaces receiving events from other interfaces
503 * delay sending initial EAPOL-Start couple of seconds to speed up
504 authentication for the most common case of Authenticator starting
505 EAP authentication immediately after association
508 * added a workaround for clearing keys with ndiswrapper to allow
509 roaming from WPA enabled AP to plaintext one
510 * added docbook documentation (doc/docbook) that can be used to
511 generate, e.g., man pages
512 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
513 PF_PACKET in order to prepare for network devices that do not use
514 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
515 * use receipt of EAPOL-Key frame as a lower layer success indication
516 for EAP state machine to allow recovery from dropped EAP-Success
518 * cleaned up internal EAPOL frame processing by not including link
519 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
520 header is added only when transmitted the frame; this makes it easier
521 to use wpa_supplicant on link layers that use different header than
523 * updated EAP-PSK to use draft 9 by default since this can now be
524 tested with hostapd; removed support for draft 3, including
525 server_nai configuration option from network blocks
526 * driver_wired: add PAE address to the multicast address list in order
527 to be able to receive EAPOL frames with drivers that do not include
528 these multicast addresses by default
529 * driver_wext: add support for WE-19
530 * added support for multiple configuration backends (CONFIG_BACKEND
531 option); currently, only 'file' is supported (i.e., the format used
532 in wpa_supplicant.conf)
533 * added support for updating configuration ('wpa_cli save_config');
534 this is disabled by default and can be enabled with global
535 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
536 and wpa_gui to store the configuration changes in a permanent store
537 * added GET_NETWORK ctrl_iface command
538 (e.g., 'wpa_cli get_network 0 ssid')
541 * replaced OpenSSL patch for EAP-FAST support
542 (openssl-tls-extensions.patch) with a more generic and correct
543 patch (the new patch is not compatible with the previous one, so the
544 OpenSSL library will need to be patched with the new patch in order
545 to be able to build wpa_supplicant with EAP-FAST support)
546 * added support for using Windows certificate store (through CryptoAPI)
547 for client certificate and private key operations (EAP-TLS)
548 (see wpa_supplicant.conf for more information on how to configure
549 this with private_key)
550 * ported wpa_gui to Windows
551 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
552 built with the open source version of the Qt4 for Windows
553 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
554 with drivers that do not support WPA
555 * ndis_events: fixed Windows 2000 support
556 * added support for enabling/disabling networks from the list of all
557 configured networks ('wpa_cli enable_network <network id>' and
558 'wpa_cli disable_network <network id>')
559 * added support for adding and removing network from the current
560 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
561 <network id>'); added networks are disabled by default and they can
562 be enabled with enable_network command once the configuration is done
563 for the new network; note: configuration file is not yet updated, so
564 these new networks are lost when wpa_supplicant is restarted
565 * added support for setting network configuration parameters through
566 the control interface, for example:
567 wpa_cli set_network 0 ssid "\"my network\""
568 * fixed parsing of strings that include both " and # within double
569 quoted area (e.g., "start"#end")
570 * added EAP workaround for PEAP session resumption: allow outer,
571 i.e., not tunneled, EAP-Success to terminate session since; this can
572 be disabled with eap_workaround=0
573 (this was allowed for PEAPv1 before, but now it is also allowed for
574 PEAPv0 since at least one RADIUS authentication server seems to be
575 doing this for PEAPv0, too)
576 * wpa_gui: added preliminary support for adding new networks to the
577 wpa_supplicant configuration (double click on the scan results to
578 open network configuration)
581 * removed interface for external EAPOL/EAP supplicant (e.g.,
582 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
583 anymore and is unlikely to be used by anyone
584 * driver_ndis: fixed WinPcap 3.0 support
585 * fixed build with CONFIG_DNET_PCAP=y on Linux
586 * l2_packet: moved different implementations into separate files
590 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
591 (note: ipw2100-1.1.0 is likely to require an update to work with
593 * added support for using ap_scan=2 mode with multiple network blocks;
594 wpa_supplicant will go through the networks one by one until the
595 driver reports a successful association; this uses the same order for
596 networks as scan_ssid=1 scans, i.e., the priority field is ignored
597 and the network block order in the file is used instead
598 * fixed a potential issue in RSN pre-authentication ending up using
599 freed memory if pre-authentication times out
600 * added support for matching alternative subject name extensions of the
601 authentication server certificate; new configuration variables
602 altsubject_match and altsubject_match2
603 * driver_ndis: added support for IEEE 802.1X authentication with wired
605 * added support for querying private key password (EAP-TLS) through the
606 control interface (wpa_cli/wpa_gui) if one is not included in the
608 * driver_broadcom: fixed couple of memory leaks in scan result
610 * EAP-PAX is now registered as EAP type 46
611 * fixed EAP-PAX MAC calculation
612 * fixed EAP-PAX CK and ICK key derivation
613 * added support for using password with EAP-PAX (as an alternative to
614 entering key with eappsk); SHA-1 hash of the password will be used as
616 * added support for arbitrary driver interface parameters through the
617 configuration file with a new driver_param field; this adds a new
618 driver_ops function set_param()
619 * added possibility to override l2_packet module with driver interface
620 API (new send_eapol handler); this can be used to implement driver
621 specific TX/RX functions for EAPOL frames
622 * fixed ctrl_interface_group processing for the case where gid is
623 entered as a number, not group name
624 * driver_test: added support for testing hostapd with wpa_supplicant
625 by using test driver interface without any kernel drivers or network
629 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
630 packets to be encrypted; this was apparently broken by the changed
631 ioctl order in v0.4.0
632 * driver_madwifi: added preliminary support for compiling against 'BSD'
633 branch of madwifi CVS tree
634 * added support for EAP-MSCHAPv2 password retries within the same EAP
635 authentication session
636 * added support for password changes with EAP-MSCHAPv2 (used when the
637 password has expired)
638 * added support for reading additional certificates from PKCS#12 files
639 and adding them to the certificate chain
640 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
642 * fixed a possible double free in EAP-TTLS fast-reauthentication when
643 identity or password is entered through control interface
644 * display EAP Notification messages to user through control interface
645 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
646 * added GUI version of wpa_cli, wpa_gui; this is not build
647 automatically with 'make'; use 'make wpa_gui' to build (this requires
648 Qt development tools)
649 * added 'disconnect' command to control interface for setting
650 wpa_supplicant in state where it will not associate before
651 'reassociate' command has been used
652 * added support for selecting a network from the list of all configured
653 networks ('wpa_cli select_network <network id>'; this disabled all
654 other networks; to re-enable, 'wpa_cli select_network any')
655 * added support for getting scan results through control interface
656 * added EAP workaround for PEAPv1 session resumption: allow outer,
657 i.e., not tunneled, EAP-Success to terminate session since; this can
658 be disabled with eap_workaround=0
660 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
661 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
662 used to reduce the size of the wpa_supplicant considerably if
663 debugging code is not needed
664 * fixed EAPOL-Key validation to drop packets with invalid Key Data
665 Length; such frames could have crashed wpa_supplicant due to buffer
667 * added support for wired authentication (IEEE 802.1X on wired
668 Ethernet); driver interface 'wired'
669 * obsoleted set_wpa() handler in the driver interface API (it can be
670 replaced by moving enable/disable functionality into init()/deinit())
671 (calls to set_wpa() are still present for backwards compatibility,
672 but they may be removed in the future)
673 * driver_madwifi: fixed association in plaintext mode
674 * modified the EAP workaround that accepts EAP-Success with incorrect
675 Identifier to be even less strict about verification in order to
676 interoperate with some authentication servers
677 * added support for sending TLS alerts
678 * added support for 'any' SSID wildcard; if ssid is not configured or
679 is set to an empty string, any SSID will be accepted for non-WPA AP
680 * added support for asking PIN (for SIM) from frontends (e.g.,
681 wpa_cli); if a PIN is needed, but not included in the configuration
682 file, a control interface request is sent and EAP processing is
683 delayed until the PIN is available
684 * added support for using external devices (e.g., a smartcard) for
685 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
686 new wpa_supplicant.conf variables:
687 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
688 - network: engine, engine_id, key_id
689 * added experimental support for EAP-PAX
690 * added monitor mode for wpa_cli (-a<path to a program to run>) that
691 allows external commands (e.g., shell scripts) to be run based on
692 wpa_supplicant events, e.g., when authentication has been completed
693 and data connection is ready; other related wpa_cli arguments:
694 -B (run in background), -P (write PID file); wpa_supplicant has a new
695 command line argument (-W) that can be used to make it wait until a
696 control interface command is received in order to avoid missing
698 * added support for opportunistic WPA2 PMKSA key caching (disabled by
699 default, can be enabled with proactive_key_caching=1)
700 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
701 Authenticator rejects PMKSA caching attempt and the driver is not
702 using assoc_info events
703 * added -P<pid file> argument for wpa_supplicant to write the current
704 process id into a file
706 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
707 * added new phase1 option parameter, include_tls_length=1, to force
708 wpa_supplicant to add TLS Message Length field to all TLS messages
709 even if the packet is not fragmented; this may be needed with some
710 authentication servers
711 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
712 using drivers that take care of AP selection (e.g., when using
714 * fixed reprocessing of pending request after ctrl_iface requests for
715 identity/password/otp
716 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
717 EAP-PEAP and EAP-TTLS
718 * all drivers using driver_wext: set interface up and select Managed
719 mode when starting wpa_supplicant; set interface down when exiting
720 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
721 ipw2100 and ipw2200; please note that this also changed the
722 configuration variable in .config to CONFIG_DRIVER_IPW
725 * fixed a busy loop introduced in v0.3.5 for scan result processing
726 when no matching AP is found
729 * added a workaround for an interoperability issue with a Cisco AP
731 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
732 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
733 retransmission of dropped frames)
734 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
735 (e.g., segfault when processing EAPOL-Key frames)
736 * fixed EAP workaround and fast reauthentication configuration for
737 RSN pre-authentication; previously these were disabled and
738 pre-authentication would fail if the used authentication server
739 requires EAP workarounds
740 * added support for blacklisting APs that fail or timeout
741 authentication in ap_scan=1 mode so that all APs are tried in cases
742 where the ones with strongest signal level are failing authentication
743 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
744 authentication attempt
745 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
746 in the previous authentication (previously, only Phase 1 success was
750 * added preliminary support for IBSS (ad-hoc) mode configuration
751 (mode=1 in network block); this included a new key_mgmt mode
752 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
753 key management; see wpa_supplicant.conf for more details and an
754 example on how to configure this (note: this is currently implemented
755 only for driver_hostapd.c, but the changes should be trivial to add
756 in associate() handler for other drivers, too (assuming the driver
758 * added preliminary port for native Windows (i.e., no cygwin) using
762 * added optional support for GNU Readline and History Libraries for
763 wpa_cli (CONFIG_READLINE)
764 * cleaned up EAP state machine <-> method interface and number of
765 small problems with error case processing not terminating on
766 EAP-Failure but waiting for timeout
767 * added couple of workarounds for interoperability issues with a
768 Cisco AP when using WPA2
769 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
770 Note: This requires a patch for openssl to add support for TLS
771 extensions and number of workarounds for operations without
772 certificates. Proof of concept type of experimental patch is
773 included in openssl-tls-extensions.patch.
776 * fixed private key loading for cases where passphrase is not set
777 * fixed Windows/cygwin L2 packet handler freeing; previous version
778 could cause a segfault when RSN pre-authentication was completed
779 * added support for PMKSA caching with drivers that generate RSN IEs
780 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
781 but similar code can be easily added to driver_ndiswrapper.c once
782 ndiswrapper gets full support for RSN PMKSA caching
783 * improved recovery from PMKID mismatches by requesting full EAP
784 authentication in case of failed PMKSA caching attempt
785 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
786 (this requires that ndis_events is ran while wpa_supplicant is
788 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
789 * added support for driver interfaces to replace the interface name
790 based on driver/OS specific mapping, e.g., in case of driver_ndis,
791 this allows the beginning of the adapter description to be used as
793 * added support for CR+LF (Windows-style) line ends in configuration
795 * driver_ndis: enable radio before starting scanning, disable radio
797 * modified association event handler to set portEnabled = FALSE before
798 clearing port Valid in order to reset EAP state machine and avoid
799 problems with new authentication getting ignored because of state
800 machines ending up in AUTHENTICATED/SUCCESS state based on old
802 * added support for driver events to add PMKID candidates in order to
803 allow drivers to give priority to most likely roaming candidates
804 * driver_hostap: moved PrivacyInvoked configuration to associate()
805 function so that this will not be set for plaintext connections
806 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
807 interface can distinguish plaintext and IEEE 802.1X (no WPA)
809 * fixed static WEP key configuration to use broadcast/default type for
810 all keys (previously, the default TX key was configured as pairwise/
812 * driver_ndis: added legacy WPA capability detection for non-WPA2
814 * added support for setting static WEP keys for IEEE 802.1X without
815 dynamic WEP keying (eapol_flags=0)
818 * added support for reading PKCS#12 (PFX) files (as a replacement for
819 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
820 * fixed compilation with CONFIG_PCSC=y
821 * added new ap_scan mode, ap_scan=2, for drivers that take care of
822 association, but need to be configured with security policy and SSID,
823 e.g., ndiswrapper and NDIS driver; this mode should allow such
824 drivers to work with hidden SSIDs and optimized roaming; when
825 ap_scan=2 is used, only the first network block in the configuration
826 file is used and this configuration should have explicit security
827 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
828 group, proto variables
829 * added experimental port of wpa_supplicant for Windows
830 - driver_ndis.c driver interface (NDIS OIDs)
831 - currently, this requires cygwin and WinPcap
832 - small utility, win_if_list, can be used to get interface name
833 * control interface can now be removed at build time; add
834 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
835 * optional Xsupplicant interface can now be removed at build time;
836 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
837 * added auth_alg to driver interface associate() parameters to make it
838 easier for drivers to configure authentication algorithm as part of
841 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
842 * driver_broadcom: added new driver interface for Broadcom wl.o driver
843 (a generic driver for Broadcom IEEE 802.11a/g cards)
844 * wpa_cli: fixed parsing of -p <path> command line argument
845 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
846 ACK, not tunneled EAP-Success (of which only the first byte was
847 actually send due to a bug in previous code); this seems to
848 interoperate with most RADIUS servers that implements PEAPv1
849 * PEAPv1: added support for terminating PEAP authentication on tunneled
850 EAP-Success message; this can be configured by adding
851 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
852 (some RADIUS servers require this whereas others require a tunneled
854 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
855 the old label for key derivation; previously, the default was 1,
856 but it looks like most existing PEAPv1 implementations use the old
857 label which is thus more suitable default option
858 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
859 * fixed parsing of wep_tx_keyidx
860 * added support for configuring list of allowed Phase 2 EAP types
861 (for both EAP-PEAP and EAP-TTLS) instead of only one type
862 * added support for configuring IEEE 802.11 authentication algorithm
863 (auth_alg; mainly for using Shared Key authentication with static
865 * added support for EAP-AKA (with UMTS SIM)
866 * fixed couple of errors in PCSC handling that could have caused
867 random-looking errors for EAP-SIM
868 * added support for EAP-SIM pseudonyms and fast re-authentication
869 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
871 * added support for EAP-SIM with two challanges
872 (phase1="sim_min_num_chal=3" can be used to require three challenges)
873 * added support for configuring DH/DSA parameters for an ephemeral DH
874 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
875 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
876 and optional DH key exchange to achieve forward secracy with RSA keys
877 * added support for matching subject of the authentication server
878 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
879 configuration variables subject_match and subject_match2
880 * changed SSID configuration in driver_wext.c (used by many driver
881 interfaces) to use ssid_len+1 as the length for SSID since some Linux
883 * fixed couple of unaligned reads in scan result parsing to fix WPA
884 connection on some platforms (e.g., ARM)
885 * added driver interface for Intel ipw2100 driver
886 * added support for LEAP with WPA
887 * added support for larger scan results report (old limit was 4 kB of
888 data, i.e., about 35 or so APs) when using Linux wireless extensions
890 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
891 only if there is a PMKSA cache entry for the current AP
892 * fixed error handling for case where reading of scan results fails:
893 must schedule a new scan or wpa_supplicant will remain waiting
895 * changed debug output to remove shared password/key material by
896 default; all key information can be included with -K command line
897 argument to match the previous behavior
898 * added support for timestamping debug log messages (disabled by
899 default, can be enabled with -t command line argument)
900 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
901 if keys are not configured to be used; this fixes IEEE 802.1X mode
902 with drivers that use this information to configure whether Privacy
903 bit can be in Beacon frames (e.g., ndiswrapper)
904 * avoid clearing driver keys if no keys have been configured since last
905 key clear request; this seems to improve reliability of group key
906 handshake for ndiswrapper & NDIS driver which seems to be suffering
907 of some kind of timing issue when the keys are cleared again after
909 * changed driver interface API:
910 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
911 version is being used (now, this is set to 2; previously, it was
913 - pass pointer to private data structure to all calls
914 - the new API is not backwards compatible; all in-tree driver
915 interfaces has been converted to the new API
916 * added support for controlling multiple interfaces (radios) per
917 wpa_supplicant process; each interface needs to be listed on the
918 command line (-c, -i, -D arguments) with -N as a separator
919 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
920 * added a workaround for EAP servers that incorrectly use same Id for
921 sequential EAP packets
922 * changed libpcap/libdnet configuration to use .config variable,
923 CONFIG_DNET_PCAP, instead of requiring Makefile modification
924 * improved downgrade attack detection in IE verification of msg 3/4:
925 verify both WPA and RSN IEs, if present, not only the selected one;
926 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
927 Probe Response frame, and RSN is enabled in wpa_supplicant
929 * fixed WPA msg 3/4 processing to allow Key Data field contain other
930 IEs than just one WPA IE
931 * added support for FreeBSD and driver interface for the BSD net80211
932 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
933 required kernel mods have not yet been committed
934 * made EAP workarounds configurable; enabled by default, can be
935 disabled with network block option eap_workaround=0
937 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
938 * resolved couple of interoperability issues with EAP-PEAPv1 and
939 Phase 2 (inner EAP) fragment reassembly
940 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
941 AP is using non-zero key index for the unicast key and key index zero
942 for the broadcast key
943 * driver_hostap: fixed IEEE 802.1X WEP key updates and
944 re-authentication by allowing unencrypted EAPOL frames when not using
946 * added a new driver interface, 'wext', which uses only standard,
947 driver independent functionality in Linux wireless extensions;
948 currently, this can be used only for non-WPA IEEE 802.1X mode, but
949 eventually, this is to be extended to support full WPA/WPA2 once
950 Linux wireless extensions get support for this
951 * added support for mode in which the driver is responsible for AP
952 scanning and selection; this is disabled by default and can be
953 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
954 this mode can be used, e.g., with generic 'wext' driver interface to
955 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
956 supporting wireless extensions.
957 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
958 operation with an AP that does not include SSID in the Beacon frames)
959 * added support for new EAP authentication methods:
960 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
961 * added support for asking one-time-passwords from frontends (e.g.,
962 wpa_cli); this 'otp' command works otherwise like 'password' command,
963 but the password is used only once and the frontend will be asked for
964 a new password whenever a request from authenticator requires a
965 password; this can be used with both EAP-OTP and EAP-GTC
966 * changed wpa_cli to automatically re-establish connection so that it
967 does not need to be re-started when wpa_supplicant is terminated and
969 * improved user data (identity/password/otp) requests through
970 frontends: process pending EAPOL packets after getting new
971 information so that full authentication does not need to be
972 restarted; in addition, send pending requests again whenever a new
974 * changed control frontends to use a new directory for socket files to
975 make it easier for wpa_cli to automatically select between interfaces
976 and to provide access control for the control interface;
977 wpa_supplicant.conf: ctrl_interface is now a path
978 (/var/run/wpa_supplicant is the recommended path) and
979 ctrl_interface_group can be used to select which group gets access to
980 the control interface;
981 wpa_cli: by default, try to connect to the first interface available
982 in /var/run/wpa_supplicant; this path can be overriden with -p option
983 and an interface can be selected with -i option (i.e., in most common
984 cases, wpa_cli does not need to get any arguments)
985 * added support for LEAP
986 * added driver interface for Linux ndiswrapper
987 * added priority option for network blocks in the configuration file;
988 this allows networks to be grouped based on priority (the scan
989 results are searched for matches with network blocks in this order)
992 * sort scan results to improve AP selection
993 * fixed control interface socket removal for some error cases
994 * improved scan requesting and authentication timeout
995 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
997 * PEAP version can now be forced with phase1="peapver=<ver>"
998 (mostly for testing; by default, the highest version supported by
999 both the Supplicant and Authentication Server is selected
1001 * added support for madwifi driver (Atheros ar521x)
1002 * added a workaround for cases where AP sets Install Tx/Rx bit for
1003 WPA Group Key messages when pairwise keys are used (without this,
1004 the Group Key would be used for Tx and the AP would drop frames
1006 * added GSM SIM/USIM interface for GSM authentication algorithm for
1007 EAP-SIM; this requires pcsc-lite
1008 * added support for ATMEL AT76C5XXx driver
1009 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1010 does not include key data in the EAPOL-Key frame (i.e., part of
1011 EAP keying material is used as data encryption key)
1012 * added support for using plaintext and static WEP networks
1016 * added support for new EAP authentication methods:
1017 EAP-TTLS/EAP-MD5-Challenge
1019 EAP-TTLS/EAP-MSCHAPv2
1027 EAP-PEAP/MD5-Challenge
1029 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1030 * added support for anonymous identity (to be used when identity is
1031 sent in plaintext; real identity will be used within TLS protected
1032 tunnel (e.g., with EAP-TTLS)
1033 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1034 * added support for requesting identity and password information using
1035 control interface; in other words, the password for EAP-PEAP or
1036 EAP-TTLS does not need to be included in the configuration file since
1037 a frontand (e.g., wpa_cli) can ask it from the user
1038 * improved RSN pre-authentication to use a candidate list and process
1039 all candidates from each scan; not only one per scan
1040 * fixed RSN IE and WPA IE capabilities field parsing
1041 * ignore Tx bit in GTK IE when Pairwise keys are used
1042 * avoid making new scan requests during IEEE 802.1X negotiation
1043 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1044 with TLS support (this replaces the included implementation with
1045 library code to save about 8 kB since the library code is needed
1047 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1048 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1051 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1053 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1054 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1055 - EAP-MD5 (cannot be used with WPA-RADIUS)
1056 [draft-ietf-eap-rfc2284bis-09.txt]
1057 - EAP-TLS [RFC 2716]
1058 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1059 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1060 [draft-kamath-pppext-eap-mschapv2-00.txt]
1061 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1062 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1063 - new configuration file options: eap, identity, password, ca_cert,
1064 client_cert, privatekey, private_key_passwd
1065 - Xsupplicant is not required anymore, but it can be used by
1066 disabling the internal IEEE 802.1X Supplicant with -e command line
1068 - this code is not included in the default build; Makefile need to
1069 be edited for this (uncomment lines for selected functionality)
1070 - EAP-TLS and EAP-PEAP require openssl libraries
1071 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1072 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1073 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1074 EAPOL-Key frames instead of WPA key handshakes)
1075 * added support for IEEE 802.11i/RSN (WPA2)
1076 - improved PTK Key Handshake
1077 - PMKSA caching, pre-authentication
1078 * fixed wpa_supplicant to ignore possible extra data after WPA
1079 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1080 TPTK' error from message 3 of 4-Way Handshake in case the AP
1081 includes extra data after the EAPOL-Key)
1082 * added interface for external programs (frontends) to control
1084 - CLI example (wpa_cli) with interactive mode and command line
1086 - replaced SIGUSR1 status/statistics with the new control interface
1087 * made some feature compile time configurable
1088 - .config file for make
1089 - driver interfaces (hostap, hermes, ..)
1090 - EAPOL/EAP functions
1093 * Initial version of wpa_supplicant
