1 ChangeLog for wpa_supplicant
4 * removed 'nai' and 'eappsk' network configuration variables that were
5 previously used for configuring user identity and key for EAP-PSK,
6 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
7 replacement for 'nai' (if old configuration used a separate
8 'identity' value, that would now be configured as
9 'anonymous_identity'). 'password' field is now used as the
10 replacement for 'eappsk' (it can also be set using hexstring to
11 present random binary data)
12 * removed '-w' command line parameter (wait for interface to be added,
13 if needed); cleaner way of handling this functionality is to use an
14 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
15 when an interface is added
16 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
17 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
18 indicating when new scan results become available
19 * added new ctrl_iface command, BSS, to allow scan results to be
20 fetched without hitting the message size limits (this command
21 can be used to iterate through the scan results one BSS at the time)
22 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
23 attributes in EAP-SIM Start/Response when using fast reauthentication
24 * fixed EAPOL not to end up in infinite loop when processing dynamic
25 WEP keys with IEEE 802.1X
26 * fixed problems in getting NDIS events from WMI on Windows 2000
29 * added support for Makefile builds to include debug-log-to-a-file
30 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
31 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
32 lengths properly to avoid potential crash caused by invalid messages
33 * added data structure for storing allocated buffers (struct wpabuf);
34 this does not affect wpa_supplicant usage, but many of the APIs
35 changed and various interfaces (e.g., EAP) is not compatible with old
37 * added support for protecting EAP-AKA/Identity messages with
38 AT_CHECKCODE (optional feature in RFC 4187)
39 * added support for protected result indication with AT_RESULT_IND for
40 EAP-SIM and EAP-AKA (phase1="result_ind=1")
41 * added driver_wext workaround for race condition between scanning and
42 association with drivers that take very long time to scan all
43 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
44 using a longer hardcoded timeout for the scan if the driver supports
45 notifications for scan completion (SIOCGIWSCAN event); this helps,
46 e.g., in cases where wpa_supplicant and madwifi driver ended up in
47 loop where the driver did not even try to associate
48 * stop EAPOL timer tick when no timers are in use in order to reduce
49 power consumption (no need to wake up the process once per second)
51 * added support for privilege separation (run only minimal part of
52 wpa_supplicant functionality as root and rest as unprivileged,
53 non-root process); see 'Privilege separation' in README for details;
54 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
56 * changed scan results data structure to include all information
57 elements to make it easier to support new IEs; old get_scan_result()
58 driver_ops is still supported for backwards compatibility (results
59 are converted internally to the new format), but all drivers should
60 start using the new get_scan_results2() to make them more likely to
61 work with new features
62 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
63 application, i.e., it does not require Qt3Support anymore; Windows
64 binary of wpa_gui.exe is now from this directory and only requires
65 QtCore4.dll and QtGui4.dll libraries
66 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
67 available as a separate package to make wpa_gui installation easier:
68 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
69 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
70 only shared key/password authentication is supported in this version
73 * added support for configuring password as NtPasswordHash
74 (16-byte MD4 hash of password) in hash:<32 hex digits> format
75 * added support for fallback from abbreviated TLS handshake to
76 full handshake when using EAP-FAST (e.g., due to an expired
78 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
79 draft (draft-ietf-emu-eap-gpsk-07.txt)
80 * added support for drivers that take care of RSN 4-way handshake
81 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
82 WPA_ALG_PMK in set_key)
83 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
84 .config); this version supports only ap_scan=2 mode and allow the
85 driver to take care of the 4-way handshake
86 * fixed a buffer overflow in parsing TSF from scan results when using
87 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
89 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
90 * fixed an integer overflow issue in the ASN.1 parser used by the
91 (experimental) internal TLS implementation to avoid a potential
93 * fixed a race condition with -W option (wait for a control interface
94 monitor before starting) that could have caused the first messages to
96 * added support for processing TNCC-TNCS-Messages to report
97 recommendation (allow/none/isolate) when using TNC [Bug 243]
100 * added network configuration parameter 'frequency' for setting
101 initial channel for IBSS (adhoc) networks
102 * added experimental IEEE 802.11r/D6.0 support
103 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
104 * updated EAP-PSK to use the IANA-allocated EAP type 47
105 * fixed EAP-PAX key derivation
106 * fixed EAP-PSK bit ordering of the Flags field
107 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
108 tunnelled identity request (previously, the identifier from the outer
109 method was used, not the tunnelled identifier which could be
111 * added support for fragmentation of outer TLS packets during Phase 2
112 of EAP-PEAP/TTLS/FAST
113 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
114 * added support for EAP-FAST authentication with inner methods that
115 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
116 for PAC provisioning)
117 * added support for authenticated EAP-FAST provisioning
118 * added support for configuring maximum number of EAP-FAST PACs to
119 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
120 * added support for storing EAP-FAST PACs in binary format
121 (fast_pac_format=binary in phase1 string)
122 * fixed dbus ctrl_iface to validate message interface before
123 dispatching to avoid a possible segfault [Bug 190]
124 * fixed PeerKey key derivation to use the correct PRF label
125 * updated Windows binary build to link against OpenSSL 0.9.8d and
126 added support for EAP-FAST
127 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
128 draft (draft-ietf-emu-eap-gpsk-04.txt)
129 * fixed EAP-AKA Notification processing to allow Notification to be
130 processed after AKA Challenge response has been sent
131 * updated to use IEEE 802.11w/D2.0 for management frame protection
133 * fixed EAP-TTLS implementation not to crash on use of freed memory
134 if TLS library initialization fails
135 * added support for EAP-TNC (Trusted Network Connect)
136 (this version implements the EAP-TNC method and EAP-TTLS changes
137 needed to run two methods in sequence (IF-T) and the IF-IMC and
138 IF-TNCCS interfaces from TNCC)
141 * added experimental, integrated TLSv1 client implementation with the
142 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
143 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
144 .config); this can be useful, e.g., if the target system does not
145 have a suitable TLS library and a minimal code size is required
146 (total size of this internal TLS/crypto code is bit under 50 kB on
147 x86 and the crypto code is shared by rest of the supplicant so some
148 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
149 * removed STAKey handshake since PeerKey handshake has replaced it in
150 IEEE 802.11ma and there are no known deployments of STAKey
151 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
152 draft (draft-ietf-emu-eap-gpsk-01.txt)
153 * added preliminary implementation of IEEE 802.11w/D1.0 (management
155 (Note: this requires driver support to work properly.)
156 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
157 * fixed Windows named pipes ctrl_iface to not stop listening for
158 commands if client program opens a named pipe and closes it
159 immediately without sending a command
160 * fixed USIM PIN status determination for the case that PIN is not
161 needed (this allows EAP-AKA to be used with USIM cards that do not
163 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
164 be used with cards that do not support file selection based on
166 * added support for matching the subjectAltName of the authentication
167 server certificate against multiple name components (e.g.,
168 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
169 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
170 affects IEEE 802.1X with dynamic WEP keys)
171 * changed ctrl_iface network configuration 'get' operations to not
172 return password/key material; if these fields are requested, "*"
173 will be returned if the password/key is set, but the value of the
174 parameter is not exposed
177 * added support for building Windows version with UNICODE defined
178 (wide-char functions)
179 * driver_ndis: fixed static WEP configuration to avoid race condition
180 issues with some NDIS drivers between association and setting WEP
182 * driver_ndis: added validation for IELength value in scan results to
183 avoid crashes when using buggy NDIS drivers [Bug 165]
184 * fixed Release|Win32 target in the Visual Studio project files
185 (previously, only Debug|Win32 target was set properly)
186 * changed control interface API call wpa_ctrl_pending() to allow it to
187 return -1 on error (e.g., connection lost); control interface clients
188 will need to make sure that they verify that the value is indeed >0
189 when determining whether there are pending messages
190 * added an alternative control interface backend for Windows targets:
191 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
192 control interface mechanism for Windows builds (previously, UDP to
194 * changed ctrl_interface configuration for UNIX domain sockets:
195 - deprecated ctrl_interface_group variable (it may be removed in
197 - allow both directory and group be configured with ctrl_interface
198 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
199 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
200 case when group is not changed
201 * added support for controlling more than one interface per process in
203 * added a workaround for a case where the AP is using unknown address
204 (e.g., MAC address of the wired interface) as the source address for
205 EAPOL-Key frames; previously, that source address was used as the
206 destination for EAPOL-Key frames and in key derivation; now, BSSID is
207 used even if the source address does not match with it
208 (this resolves an interoperability issue with Thomson SpeedTouch 580)
209 * added a workaround for UDP-based control interface (which was used in
210 Windows builds before this release) to prevent packets with forged
211 addresses from being accepted as local control requests
212 * removed ndis_events.cpp and possibility of using external
213 ndis_events.exe; C version (ndis_events.c) is fully functional and
214 there is no desire to maintain two separate versions of this
216 * ndis_events: Changed NDIS event notification design to use WMI to
217 learn the adapter description through Win32_PnPEntity class; this
218 should fix some cases where the adapter name was not recognized
219 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
221 * fixed selection of the first network in ap_scan=2 mode; previously,
222 wpa_supplicant could get stuck in SCANNING state when only the first
223 network for enabled (e.g., after 'wpa_cli select_network 0')
224 * winsvc: added support for configuring ctrl_interface parameters in
225 registry (ctrl_interface string value in
226 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
227 required to enable control interface (previously, this was hardcoded
229 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
230 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
233 * fixed build with CONFIG_STAKEY=y [Bug 143]
234 * added support for doing MLME (IEEE 802.11 management frame
235 processing) in wpa_supplicant when using Devicescape IEEE 802.11
236 stack (wireless-dev.git tree)
237 * added a new network block configuration option, fragment_size, to
238 configure the maximum EAP fragment size
239 * driver_ndis: Disable WZC automatically for the selected interface to
240 avoid conflicts with two programs trying to control the radio; WZC
241 will be re-enabled (if it was enabled originally) when wpa_supplicant
243 * added an experimental TLSv1 client implementation
244 (CONFIG_TLS=internal) that can be used instead of an external TLS
245 library, e.g., to reduce total size requirement on systems that do
246 not include any TLS library by default (this is not yet complete;
247 basic functionality is there, but certificate validation is not yet
249 * added PeerKey handshake implementation for IEEE 802.11e
250 direct link setup (DLS) to replace STAKey handshake
251 * fixed WPA PSK update through ctrl_iface for the case where the old
252 PSK was derived from an ASCII passphrase and the new PSK is set as
253 a raw PSK (hex string)
254 * added new configuration option for identifying which network block
255 was used (id_str in wpa_supplicant.conf; included on
256 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
257 variable in wpa_cli action scripts; in addition WPA_ID variable is
258 set to the current unique identifier that wpa_supplicant assigned
259 automatically for the network and that can be used with
260 GET_NETWORK/SET_NETWORK ctrl_iface commands)
261 * wpa_cli action script is now called only when the connect/disconnect
262 status changes or when associating with a different network
263 * fixed configuration parser not to remove CCMP from group cipher list
264 if WPA-None (adhoc) is used (pairwise=NONE in that case)
265 * fixed integrated NDIS events processing not to hang the process due
266 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
267 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
268 draft-clancy-emu-eap-shared-secret-00.txt)
269 * added Microsoft Visual Studio 2005 solution and project files for
270 build wpa_supplicant for Windows (see vs2005 subdirectory)
271 * eloop_win: fixed unregistration of Windows events
272 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
273 at the end of RSN pre-authentication and added unregistration of
274 a Windows event to avoid getting eloop_win stuck with an invalid
276 * driver_ndis: added support for selecting AP based on BSSID
277 * added new environmental variable for wpa_cli action scripts:
278 WPA_CTRL_DIR is the current control interface directory
279 * driver_ndis: added support for using NDISUIO instead of WinPcap for
280 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
281 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
282 wpa_supplicant without requiring WinPcap; note that using NDISUIO
283 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
284 only one application to open the device
285 * changed NDIS driver naming to only include device GUID, e.g.,
286 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
287 specific \Device\NPF_ prefix before the GUID; the prefix is still
288 allowed for backwards compatibility, but it is not required anymore
289 when specifying the interface
290 * driver_ndis: re-initialize driver interface is the adapter is removed
291 and re-inserted [Bug 159]
292 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
293 big endian hosts [Bug 146]
296 * fixed EAP-GTC response to include correct user identity when run as
297 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
298 * driver_ndis: Fixed encryption mode configuration for unencrypted
299 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
300 refused to associate with open networks) [Bug 106]
301 * driver_ndis: use BSSID OID polling to detect when IBSS network is
302 formed even when ndis_events code is included since some NDIS drivers
303 do not generate media connect events in IBSS mode
304 * config_winreg: allow global ctrl_interface parameter to be configured
306 * config_winreg: added support for saving configuration data into
308 * added support for controlling network device operational state
309 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
310 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
311 that can use this information)
312 * driver_wext: added support for WE-21 change to SSID configuration
313 * driver_wext: fixed privacy configuration for static WEP keys mode
315 * added an optional driver_ops callback for MLME-SETPROTECTION.request
317 * added support for EAP-SAKE (no EAP method number allocated yet, so
318 this is using the same experimental type 255 as EAP-PSK)
319 * added support for dynamically loading EAP methods (.so files) instead
320 of requiring them to be statically linked in; this is disabled by
321 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
325 * do not try to use USIM APDUs when initializing PC/SC for SIM card
326 access for a network that has not enabled EAP-AKA
327 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
328 v0.5.1 due to the new support for expanded EAP types)
329 * added support for generating EAP Expanded Nak
330 * try to fetch scan results once before requesting new scan when
331 starting up in ap_scan=1 mode (this can speed up initial association
332 a lot with, e.g., madwifi-ng driver)
333 * added support for receiving EAPOL frames from a Linux bridge
334 interface (-bbr0 on command line)
335 * fixed EAPOL re-authentication for sessions that used PMKSA caching
336 * changed EAP method registration to use a dynamic list of methods
337 instead of a static list generated at build time
338 * fixed PMKSA cache deinitialization not to use freed memory when
339 removing PMKSA entries
340 * fixed a memory leak in EAP-TTLS re-authentication
341 * reject WPA/WPA2 message 3/4 if it does not include any valid
343 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
344 if the driver does not support SIOCSIWAUTH
347 * driver_test: added better support for multiple APs and STAs by using
348 a directory with sockets that include MAC address for each device in
349 the name (driver_param=test_dir=/tmp/test)
350 * added support for EAP expanded type (vendor specific EAP methods)
351 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
352 option can be changed if needed
353 * wpa_cli/wpa_gui: skip non-socket files in control directory when
354 using UNIX domain sockets; this avoids selecting an incorrect
355 interface (e.g., a PID file could be in this directory, even though
356 use of this directory for something else than socket files is not
358 * fixed TLS library deinitialization after RSN pre-authentication not
359 to disable TLS library for normal authentication
360 * driver_wext: Remove null-termination from SSID length if the driver
361 used it; some Linux drivers do this and they were causing problems in
362 wpa_supplicant not finding matching configuration block. This change
363 would break a case where the SSID actually ends in '\0', but that is
364 not likely to happen in real use.
365 * fixed PMKSA cache processing not to trigger deauthentication if the
366 current PMKSA cache entry is replaced with a valid new entry
367 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
368 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
371 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
372 * added experimental STAKey handshake implementation for IEEE 802.11e
373 direct link setup (DLS); note: this is disabled by default in both
374 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
376 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
377 decrypt AT_ENCR_DATA attributes correctly
378 * fixed EAP-AKA to allow resynchronization within the same session
379 * made code closer to ANSI C89 standard to make it easier to port to
380 other C libraries and compilers
381 * started moving operating system or C library specific functions into
382 wrapper functions defined in os.h and implemented in os_*.c to make
384 * wpa_supplicant can now be built with Microsoft Visual C++
385 (e.g., with the freely available Toolkit 2003 version or Visual
386 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
387 example makefile for nmake
388 * added support for using Windows registry for command line parameters
389 (CONFIG_MAIN=main_winsvc) and configuration data
390 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
391 contents; this version can be run both as a Windows service and as a
392 normal application; 'wpasvc.exe app' to start as applicant,
393 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
394 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
396 * made it possible to link ndis_events.exe functionality into
397 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
398 * added better support for multiple control interface backends
399 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
400 * fixed PC/SC code to use correct length for GSM AUTH command buffer
401 and to not use pioRecvPci with SCardTransmit() calls; these were not
402 causing visible problems with pcsc-lite, but Windows Winscard.dll
403 refused the previously used parameters; this fixes EAP-SIM and
404 EAP-AKA authentication using SIM/USIM card under Windows
405 * added new event loop implementation for Windows using
406 WaitForMultipleObject() instead of select() in order to allow waiting
407 for non-socket objects; this can be selected with
408 CONFIG_ELOOP=eloop_win in .config
409 * added support for selecting l2_packet implementation in .config
410 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
411 winpcap, freebsd, none)
412 * added new l2_packet implementation for WinPcap
413 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
414 reduce latency in EAPOL receive processing from about 100 ms to about
416 * added support for EAP-FAST key derivation using other ciphers than
417 RC4-128-SHA for authentication and AES128-SHA for provisioning
418 * added support for configuring CA certificate as DER file and as a
420 * fixed private key configuration as configuration blob and added
421 support for using PKCS#12 as a blob
422 * tls_gnutls: added support for using PKCS#12 files; added support for
424 * added support for loading trusted CA certificates from Windows
425 certificate store: ca_cert="cert_store://<name>", where <name> is
426 likely CA (Intermediate CA certificates) or ROOT (root certificates)
427 * added C version of ndis_events.cpp and made it possible to build this
428 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
429 easily on cross-compilation builds
430 * added wpasvc.exe into Windows binary release; this is an alternative
431 version of wpa_supplicant.exe with configuration backend using
432 Windows registry and with the entry point designed to run as a
434 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
435 wpasvc.exe and removed this additional tool from the Windows binary
436 release since it is not needed anymore
437 * load winscard.dll functions dynamically when building with MinGW
438 since MinGW does not yet include winscard library
440 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
441 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
442 and WinPcap to receive frames sent to PAE group address
443 * disable EAP state machine when IEEE 802.1X authentication is not used
444 in order to get rid of bogus "EAP failed" messages
445 * fixed OpenSSL error reporting to go through all pending errors to
446 avoid confusing reports of old errors being reported at later point
448 * fixed configuration file updating to not write empty variables
449 (e.g., proto or key_mgmt) that the file parser would not accept
450 * fixed ADD_NETWORK ctrl_iface command to use the same default values
451 for variables as empty network definitions read from config file
453 * fixed EAP state machine to not discard EAP-Failure messages in many
454 cases (e.g., during TLS handshake)
455 * fixed a infinite loop in private key reading if the configured file
456 cannot be parsed successfully
457 * driver_madwifi: added support for madwifi-ng
458 * wpa_gui: do not display password/PSK field contents
459 * wpa_gui: added CA certificate configuration
460 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
461 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
462 the new AP is using different WPA/RSN IE
463 * use longer timeout for IEEE 802.11 association to avoid problems with
464 drivers that may take more than five second to associate
467 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
468 RSN IE, but WPA IE would match with wpa_supplicant configuration
469 * added support for named configuration blobs in order to avoid having
470 to use file system for external files (e.g., certificates);
471 variables can be set to "blob://<blob name>" instead of file path to
472 use a named blob; supported fields: pac_file, client_cert,
474 * fixed RSN pre-authentication (it was broken in the clean up of WPA
475 state machine interface in v0.4.5)
476 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
477 sure the driver configures broadcast decryption correctly
478 * added ca_path (and ca_path2) configuration variables that can be used
479 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
480 system-wide trusted CA list
481 * added support for starting wpa_supplicant without a configuration
482 file (-C argument must be used to set ctrl_interface parameter for
483 this case; in addition, -p argument can be used to provide
484 driver_param; these new arguments can also be used with a
485 configuration to override the values from the configuration)
486 * added global control interface that can be optionally used for adding
487 and removing network interfaces dynamically (-g command line argument
488 for both wpa_supplicant and wpa_cli) without having to restart
489 wpa_supplicant process
491 - try to save configuration whenever something is modified
492 - added WEP key configuration
493 - added possibility to edit the current network configuration
494 * driver_ndis: fixed driver polling not to increase frequency on each
495 received EAPOL frame due to incorrectly cancelled timeout
496 * added simple configuration file examples (in examples subdirectory)
497 * fixed driver_wext.c to filter wireless events based on ifindex to
498 avoid interfaces receiving events from other interfaces
499 * delay sending initial EAPOL-Start couple of seconds to speed up
500 authentication for the most common case of Authenticator starting
501 EAP authentication immediately after association
504 * added a workaround for clearing keys with ndiswrapper to allow
505 roaming from WPA enabled AP to plaintext one
506 * added docbook documentation (doc/docbook) that can be used to
507 generate, e.g., man pages
508 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
509 PF_PACKET in order to prepare for network devices that do not use
510 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
511 * use receipt of EAPOL-Key frame as a lower layer success indication
512 for EAP state machine to allow recovery from dropped EAP-Success
514 * cleaned up internal EAPOL frame processing by not including link
515 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
516 header is added only when transmitted the frame; this makes it easier
517 to use wpa_supplicant on link layers that use different header than
519 * updated EAP-PSK to use draft 9 by default since this can now be
520 tested with hostapd; removed support for draft 3, including
521 server_nai configuration option from network blocks
522 * driver_wired: add PAE address to the multicast address list in order
523 to be able to receive EAPOL frames with drivers that do not include
524 these multicast addresses by default
525 * driver_wext: add support for WE-19
526 * added support for multiple configuration backends (CONFIG_BACKEND
527 option); currently, only 'file' is supported (i.e., the format used
528 in wpa_supplicant.conf)
529 * added support for updating configuration ('wpa_cli save_config');
530 this is disabled by default and can be enabled with global
531 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
532 and wpa_gui to store the configuration changes in a permanent store
533 * added GET_NETWORK ctrl_iface command
534 (e.g., 'wpa_cli get_network 0 ssid')
537 * replaced OpenSSL patch for EAP-FAST support
538 (openssl-tls-extensions.patch) with a more generic and correct
539 patch (the new patch is not compatible with the previous one, so the
540 OpenSSL library will need to be patched with the new patch in order
541 to be able to build wpa_supplicant with EAP-FAST support)
542 * added support for using Windows certificate store (through CryptoAPI)
543 for client certificate and private key operations (EAP-TLS)
544 (see wpa_supplicant.conf for more information on how to configure
545 this with private_key)
546 * ported wpa_gui to Windows
547 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
548 built with the open source version of the Qt4 for Windows
549 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
550 with drivers that do not support WPA
551 * ndis_events: fixed Windows 2000 support
552 * added support for enabling/disabling networks from the list of all
553 configured networks ('wpa_cli enable_network <network id>' and
554 'wpa_cli disable_network <network id>')
555 * added support for adding and removing network from the current
556 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
557 <network id>'); added networks are disabled by default and they can
558 be enabled with enable_network command once the configuration is done
559 for the new network; note: configuration file is not yet updated, so
560 these new networks are lost when wpa_supplicant is restarted
561 * added support for setting network configuration parameters through
562 the control interface, for example:
563 wpa_cli set_network 0 ssid "\"my network\""
564 * fixed parsing of strings that include both " and # within double
565 quoted area (e.g., "start"#end")
566 * added EAP workaround for PEAP session resumption: allow outer,
567 i.e., not tunneled, EAP-Success to terminate session since; this can
568 be disabled with eap_workaround=0
569 (this was allowed for PEAPv1 before, but now it is also allowed for
570 PEAPv0 since at least one RADIUS authentication server seems to be
571 doing this for PEAPv0, too)
572 * wpa_gui: added preliminary support for adding new networks to the
573 wpa_supplicant configuration (double click on the scan results to
574 open network configuration)
577 * removed interface for external EAPOL/EAP supplicant (e.g.,
578 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
579 anymore and is unlikely to be used by anyone
580 * driver_ndis: fixed WinPcap 3.0 support
581 * fixed build with CONFIG_DNET_PCAP=y on Linux
582 * l2_packet: moved different implementations into separate files
586 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
587 (note: ipw2100-1.1.0 is likely to require an update to work with
589 * added support for using ap_scan=2 mode with multiple network blocks;
590 wpa_supplicant will go through the networks one by one until the
591 driver reports a successful association; this uses the same order for
592 networks as scan_ssid=1 scans, i.e., the priority field is ignored
593 and the network block order in the file is used instead
594 * fixed a potential issue in RSN pre-authentication ending up using
595 freed memory if pre-authentication times out
596 * added support for matching alternative subject name extensions of the
597 authentication server certificate; new configuration variables
598 altsubject_match and altsubject_match2
599 * driver_ndis: added support for IEEE 802.1X authentication with wired
601 * added support for querying private key password (EAP-TLS) through the
602 control interface (wpa_cli/wpa_gui) if one is not included in the
604 * driver_broadcom: fixed couple of memory leaks in scan result
606 * EAP-PAX is now registered as EAP type 46
607 * fixed EAP-PAX MAC calculation
608 * fixed EAP-PAX CK and ICK key derivation
609 * added support for using password with EAP-PAX (as an alternative to
610 entering key with eappsk); SHA-1 hash of the password will be used as
612 * added support for arbitrary driver interface parameters through the
613 configuration file with a new driver_param field; this adds a new
614 driver_ops function set_param()
615 * added possibility to override l2_packet module with driver interface
616 API (new send_eapol handler); this can be used to implement driver
617 specific TX/RX functions for EAPOL frames
618 * fixed ctrl_interface_group processing for the case where gid is
619 entered as a number, not group name
620 * driver_test: added support for testing hostapd with wpa_supplicant
621 by using test driver interface without any kernel drivers or network
625 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
626 packets to be encrypted; this was apparently broken by the changed
627 ioctl order in v0.4.0
628 * driver_madwifi: added preliminary support for compiling against 'BSD'
629 branch of madwifi CVS tree
630 * added support for EAP-MSCHAPv2 password retries within the same EAP
631 authentication session
632 * added support for password changes with EAP-MSCHAPv2 (used when the
633 password has expired)
634 * added support for reading additional certificates from PKCS#12 files
635 and adding them to the certificate chain
636 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
638 * fixed a possible double free in EAP-TTLS fast-reauthentication when
639 identity or password is entered through control interface
640 * display EAP Notification messages to user through control interface
641 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
642 * added GUI version of wpa_cli, wpa_gui; this is not build
643 automatically with 'make'; use 'make wpa_gui' to build (this requires
644 Qt development tools)
645 * added 'disconnect' command to control interface for setting
646 wpa_supplicant in state where it will not associate before
647 'reassociate' command has been used
648 * added support for selecting a network from the list of all configured
649 networks ('wpa_cli select_network <network id>'; this disabled all
650 other networks; to re-enable, 'wpa_cli select_network any')
651 * added support for getting scan results through control interface
652 * added EAP workaround for PEAPv1 session resumption: allow outer,
653 i.e., not tunneled, EAP-Success to terminate session since; this can
654 be disabled with eap_workaround=0
656 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
657 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
658 used to reduce the size of the wpa_supplicant considerably if
659 debugging code is not needed
660 * fixed EAPOL-Key validation to drop packets with invalid Key Data
661 Length; such frames could have crashed wpa_supplicant due to buffer
663 * added support for wired authentication (IEEE 802.1X on wired
664 Ethernet); driver interface 'wired'
665 * obsoleted set_wpa() handler in the driver interface API (it can be
666 replaced by moving enable/disable functionality into init()/deinit())
667 (calls to set_wpa() are still present for backwards compatibility,
668 but they may be removed in the future)
669 * driver_madwifi: fixed association in plaintext mode
670 * modified the EAP workaround that accepts EAP-Success with incorrect
671 Identifier to be even less strict about verification in order to
672 interoperate with some authentication servers
673 * added support for sending TLS alerts
674 * added support for 'any' SSID wildcard; if ssid is not configured or
675 is set to an empty string, any SSID will be accepted for non-WPA AP
676 * added support for asking PIN (for SIM) from frontends (e.g.,
677 wpa_cli); if a PIN is needed, but not included in the configuration
678 file, a control interface request is sent and EAP processing is
679 delayed until the PIN is available
680 * added support for using external devices (e.g., a smartcard) for
681 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
682 new wpa_supplicant.conf variables:
683 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
684 - network: engine, engine_id, key_id
685 * added experimental support for EAP-PAX
686 * added monitor mode for wpa_cli (-a<path to a program to run>) that
687 allows external commands (e.g., shell scripts) to be run based on
688 wpa_supplicant events, e.g., when authentication has been completed
689 and data connection is ready; other related wpa_cli arguments:
690 -B (run in background), -P (write PID file); wpa_supplicant has a new
691 command line argument (-W) that can be used to make it wait until a
692 control interface command is received in order to avoid missing
694 * added support for opportunistic WPA2 PMKSA key caching (disabled by
695 default, can be enabled with proactive_key_caching=1)
696 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
697 Authenticator rejects PMKSA caching attempt and the driver is not
698 using assoc_info events
699 * added -P<pid file> argument for wpa_supplicant to write the current
700 process id into a file
702 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
703 * added new phase1 option parameter, include_tls_length=1, to force
704 wpa_supplicant to add TLS Message Length field to all TLS messages
705 even if the packet is not fragmented; this may be needed with some
706 authentication servers
707 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
708 using drivers that take care of AP selection (e.g., when using
710 * fixed reprocessing of pending request after ctrl_iface requests for
711 identity/password/otp
712 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
713 EAP-PEAP and EAP-TTLS
714 * all drivers using driver_wext: set interface up and select Managed
715 mode when starting wpa_supplicant; set interface down when exiting
716 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
717 ipw2100 and ipw2200; please note that this also changed the
718 configuration variable in .config to CONFIG_DRIVER_IPW
721 * fixed a busy loop introduced in v0.3.5 for scan result processing
722 when no matching AP is found
725 * added a workaround for an interoperability issue with a Cisco AP
727 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
728 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
729 retransmission of dropped frames)
730 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
731 (e.g., segfault when processing EAPOL-Key frames)
732 * fixed EAP workaround and fast reauthentication configuration for
733 RSN pre-authentication; previously these were disabled and
734 pre-authentication would fail if the used authentication server
735 requires EAP workarounds
736 * added support for blacklisting APs that fail or timeout
737 authentication in ap_scan=1 mode so that all APs are tried in cases
738 where the ones with strongest signal level are failing authentication
739 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
740 authentication attempt
741 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
742 in the previous authentication (previously, only Phase 1 success was
746 * added preliminary support for IBSS (ad-hoc) mode configuration
747 (mode=1 in network block); this included a new key_mgmt mode
748 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
749 key management; see wpa_supplicant.conf for more details and an
750 example on how to configure this (note: this is currently implemented
751 only for driver_hostapd.c, but the changes should be trivial to add
752 in associate() handler for other drivers, too (assuming the driver
754 * added preliminary port for native Windows (i.e., no cygwin) using
758 * added optional support for GNU Readline and History Libraries for
759 wpa_cli (CONFIG_READLINE)
760 * cleaned up EAP state machine <-> method interface and number of
761 small problems with error case processing not terminating on
762 EAP-Failure but waiting for timeout
763 * added couple of workarounds for interoperability issues with a
764 Cisco AP when using WPA2
765 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
766 Note: This requires a patch for openssl to add support for TLS
767 extensions and number of workarounds for operations without
768 certificates. Proof of concept type of experimental patch is
769 included in openssl-tls-extensions.patch.
772 * fixed private key loading for cases where passphrase is not set
773 * fixed Windows/cygwin L2 packet handler freeing; previous version
774 could cause a segfault when RSN pre-authentication was completed
775 * added support for PMKSA caching with drivers that generate RSN IEs
776 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
777 but similar code can be easily added to driver_ndiswrapper.c once
778 ndiswrapper gets full support for RSN PMKSA caching
779 * improved recovery from PMKID mismatches by requesting full EAP
780 authentication in case of failed PMKSA caching attempt
781 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
782 (this requires that ndis_events is ran while wpa_supplicant is
784 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
785 * added support for driver interfaces to replace the interface name
786 based on driver/OS specific mapping, e.g., in case of driver_ndis,
787 this allows the beginning of the adapter description to be used as
789 * added support for CR+LF (Windows-style) line ends in configuration
791 * driver_ndis: enable radio before starting scanning, disable radio
793 * modified association event handler to set portEnabled = FALSE before
794 clearing port Valid in order to reset EAP state machine and avoid
795 problems with new authentication getting ignored because of state
796 machines ending up in AUTHENTICATED/SUCCESS state based on old
798 * added support for driver events to add PMKID candidates in order to
799 allow drivers to give priority to most likely roaming candidates
800 * driver_hostap: moved PrivacyInvoked configuration to associate()
801 function so that this will not be set for plaintext connections
802 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
803 interface can distinguish plaintext and IEEE 802.1X (no WPA)
805 * fixed static WEP key configuration to use broadcast/default type for
806 all keys (previously, the default TX key was configured as pairwise/
808 * driver_ndis: added legacy WPA capability detection for non-WPA2
810 * added support for setting static WEP keys for IEEE 802.1X without
811 dynamic WEP keying (eapol_flags=0)
814 * added support for reading PKCS#12 (PFX) files (as a replacement for
815 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
816 * fixed compilation with CONFIG_PCSC=y
817 * added new ap_scan mode, ap_scan=2, for drivers that take care of
818 association, but need to be configured with security policy and SSID,
819 e.g., ndiswrapper and NDIS driver; this mode should allow such
820 drivers to work with hidden SSIDs and optimized roaming; when
821 ap_scan=2 is used, only the first network block in the configuration
822 file is used and this configuration should have explicit security
823 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
824 group, proto variables
825 * added experimental port of wpa_supplicant for Windows
826 - driver_ndis.c driver interface (NDIS OIDs)
827 - currently, this requires cygwin and WinPcap
828 - small utility, win_if_list, can be used to get interface name
829 * control interface can now be removed at build time; add
830 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
831 * optional Xsupplicant interface can now be removed at build time;
832 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
833 * added auth_alg to driver interface associate() parameters to make it
834 easier for drivers to configure authentication algorithm as part of
837 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
838 * driver_broadcom: added new driver interface for Broadcom wl.o driver
839 (a generic driver for Broadcom IEEE 802.11a/g cards)
840 * wpa_cli: fixed parsing of -p <path> command line argument
841 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
842 ACK, not tunneled EAP-Success (of which only the first byte was
843 actually send due to a bug in previous code); this seems to
844 interoperate with most RADIUS servers that implements PEAPv1
845 * PEAPv1: added support for terminating PEAP authentication on tunneled
846 EAP-Success message; this can be configured by adding
847 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
848 (some RADIUS servers require this whereas others require a tunneled
850 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
851 the old label for key derivation; previously, the default was 1,
852 but it looks like most existing PEAPv1 implementations use the old
853 label which is thus more suitable default option
854 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
855 * fixed parsing of wep_tx_keyidx
856 * added support for configuring list of allowed Phase 2 EAP types
857 (for both EAP-PEAP and EAP-TTLS) instead of only one type
858 * added support for configuring IEEE 802.11 authentication algorithm
859 (auth_alg; mainly for using Shared Key authentication with static
861 * added support for EAP-AKA (with UMTS SIM)
862 * fixed couple of errors in PCSC handling that could have caused
863 random-looking errors for EAP-SIM
864 * added support for EAP-SIM pseudonyms and fast re-authentication
865 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
867 * added support for EAP-SIM with two challanges
868 (phase1="sim_min_num_chal=3" can be used to require three challenges)
869 * added support for configuring DH/DSA parameters for an ephemeral DH
870 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
871 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
872 and optional DH key exchange to achieve forward secracy with RSA keys
873 * added support for matching subject of the authentication server
874 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
875 configuration variables subject_match and subject_match2
876 * changed SSID configuration in driver_wext.c (used by many driver
877 interfaces) to use ssid_len+1 as the length for SSID since some Linux
879 * fixed couple of unaligned reads in scan result parsing to fix WPA
880 connection on some platforms (e.g., ARM)
881 * added driver interface for Intel ipw2100 driver
882 * added support for LEAP with WPA
883 * added support for larger scan results report (old limit was 4 kB of
884 data, i.e., about 35 or so APs) when using Linux wireless extensions
886 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
887 only if there is a PMKSA cache entry for the current AP
888 * fixed error handling for case where reading of scan results fails:
889 must schedule a new scan or wpa_supplicant will remain waiting
891 * changed debug output to remove shared password/key material by
892 default; all key information can be included with -K command line
893 argument to match the previous behavior
894 * added support for timestamping debug log messages (disabled by
895 default, can be enabled with -t command line argument)
896 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
897 if keys are not configured to be used; this fixes IEEE 802.1X mode
898 with drivers that use this information to configure whether Privacy
899 bit can be in Beacon frames (e.g., ndiswrapper)
900 * avoid clearing driver keys if no keys have been configured since last
901 key clear request; this seems to improve reliability of group key
902 handshake for ndiswrapper & NDIS driver which seems to be suffering
903 of some kind of timing issue when the keys are cleared again after
905 * changed driver interface API:
906 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
907 version is being used (now, this is set to 2; previously, it was
909 - pass pointer to private data structure to all calls
910 - the new API is not backwards compatible; all in-tree driver
911 interfaces has been converted to the new API
912 * added support for controlling multiple interfaces (radios) per
913 wpa_supplicant process; each interface needs to be listed on the
914 command line (-c, -i, -D arguments) with -N as a separator
915 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
916 * added a workaround for EAP servers that incorrectly use same Id for
917 sequential EAP packets
918 * changed libpcap/libdnet configuration to use .config variable,
919 CONFIG_DNET_PCAP, instead of requiring Makefile modification
920 * improved downgrade attack detection in IE verification of msg 3/4:
921 verify both WPA and RSN IEs, if present, not only the selected one;
922 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
923 Probe Response frame, and RSN is enabled in wpa_supplicant
925 * fixed WPA msg 3/4 processing to allow Key Data field contain other
926 IEs than just one WPA IE
927 * added support for FreeBSD and driver interface for the BSD net80211
928 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
929 required kernel mods have not yet been committed
930 * made EAP workarounds configurable; enabled by default, can be
931 disabled with network block option eap_workaround=0
933 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
934 * resolved couple of interoperability issues with EAP-PEAPv1 and
935 Phase 2 (inner EAP) fragment reassembly
936 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
937 AP is using non-zero key index for the unicast key and key index zero
938 for the broadcast key
939 * driver_hostap: fixed IEEE 802.1X WEP key updates and
940 re-authentication by allowing unencrypted EAPOL frames when not using
942 * added a new driver interface, 'wext', which uses only standard,
943 driver independent functionality in Linux wireless extensions;
944 currently, this can be used only for non-WPA IEEE 802.1X mode, but
945 eventually, this is to be extended to support full WPA/WPA2 once
946 Linux wireless extensions get support for this
947 * added support for mode in which the driver is responsible for AP
948 scanning and selection; this is disabled by default and can be
949 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
950 this mode can be used, e.g., with generic 'wext' driver interface to
951 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
952 supporting wireless extensions.
953 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
954 operation with an AP that does not include SSID in the Beacon frames)
955 * added support for new EAP authentication methods:
956 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
957 * added support for asking one-time-passwords from frontends (e.g.,
958 wpa_cli); this 'otp' command works otherwise like 'password' command,
959 but the password is used only once and the frontend will be asked for
960 a new password whenever a request from authenticator requires a
961 password; this can be used with both EAP-OTP and EAP-GTC
962 * changed wpa_cli to automatically re-establish connection so that it
963 does not need to be re-started when wpa_supplicant is terminated and
965 * improved user data (identity/password/otp) requests through
966 frontends: process pending EAPOL packets after getting new
967 information so that full authentication does not need to be
968 restarted; in addition, send pending requests again whenever a new
970 * changed control frontends to use a new directory for socket files to
971 make it easier for wpa_cli to automatically select between interfaces
972 and to provide access control for the control interface;
973 wpa_supplicant.conf: ctrl_interface is now a path
974 (/var/run/wpa_supplicant is the recommended path) and
975 ctrl_interface_group can be used to select which group gets access to
976 the control interface;
977 wpa_cli: by default, try to connect to the first interface available
978 in /var/run/wpa_supplicant; this path can be overriden with -p option
979 and an interface can be selected with -i option (i.e., in most common
980 cases, wpa_cli does not need to get any arguments)
981 * added support for LEAP
982 * added driver interface for Linux ndiswrapper
983 * added priority option for network blocks in the configuration file;
984 this allows networks to be grouped based on priority (the scan
985 results are searched for matches with network blocks in this order)
988 * sort scan results to improve AP selection
989 * fixed control interface socket removal for some error cases
990 * improved scan requesting and authentication timeout
991 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
993 * PEAP version can now be forced with phase1="peapver=<ver>"
994 (mostly for testing; by default, the highest version supported by
995 both the Supplicant and Authentication Server is selected
997 * added support for madwifi driver (Atheros ar521x)
998 * added a workaround for cases where AP sets Install Tx/Rx bit for
999 WPA Group Key messages when pairwise keys are used (without this,
1000 the Group Key would be used for Tx and the AP would drop frames
1002 * added GSM SIM/USIM interface for GSM authentication algorithm for
1003 EAP-SIM; this requires pcsc-lite
1004 * added support for ATMEL AT76C5XXx driver
1005 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1006 does not include key data in the EAPOL-Key frame (i.e., part of
1007 EAP keying material is used as data encryption key)
1008 * added support for using plaintext and static WEP networks
1012 * added support for new EAP authentication methods:
1013 EAP-TTLS/EAP-MD5-Challenge
1015 EAP-TTLS/EAP-MSCHAPv2
1023 EAP-PEAP/MD5-Challenge
1025 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1026 * added support for anonymous identity (to be used when identity is
1027 sent in plaintext; real identity will be used within TLS protected
1028 tunnel (e.g., with EAP-TTLS)
1029 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1030 * added support for requesting identity and password information using
1031 control interface; in other words, the password for EAP-PEAP or
1032 EAP-TTLS does not need to be included in the configuration file since
1033 a frontand (e.g., wpa_cli) can ask it from the user
1034 * improved RSN pre-authentication to use a candidate list and process
1035 all candidates from each scan; not only one per scan
1036 * fixed RSN IE and WPA IE capabilities field parsing
1037 * ignore Tx bit in GTK IE when Pairwise keys are used
1038 * avoid making new scan requests during IEEE 802.1X negotiation
1039 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1040 with TLS support (this replaces the included implementation with
1041 library code to save about 8 kB since the library code is needed
1043 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1044 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1047 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1049 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1050 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1051 - EAP-MD5 (cannot be used with WPA-RADIUS)
1052 [draft-ietf-eap-rfc2284bis-09.txt]
1053 - EAP-TLS [RFC 2716]
1054 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1055 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1056 [draft-kamath-pppext-eap-mschapv2-00.txt]
1057 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1058 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1059 - new configuration file options: eap, identity, password, ca_cert,
1060 client_cert, privatekey, private_key_passwd
1061 - Xsupplicant is not required anymore, but it can be used by
1062 disabling the internal IEEE 802.1X Supplicant with -e command line
1064 - this code is not included in the default build; Makefile need to
1065 be edited for this (uncomment lines for selected functionality)
1066 - EAP-TLS and EAP-PEAP require openssl libraries
1067 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1068 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1069 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1070 EAPOL-Key frames instead of WPA key handshakes)
1071 * added support for IEEE 802.11i/RSN (WPA2)
1072 - improved PTK Key Handshake
1073 - PMKSA caching, pre-authentication
1074 * fixed wpa_supplicant to ignore possible extra data after WPA
1075 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1076 TPTK' error from message 3 of 4-Way Handshake in case the AP
1077 includes extra data after the EAPOL-Key)
1078 * added interface for external programs (frontends) to control
1080 - CLI example (wpa_cli) with interactive mode and command line
1082 - replaced SIGUSR1 status/statistics with the new control interface
1083 * made some feature compile time configurable
1084 - .config file for make
1085 - driver interfaces (hostap, hermes, ..)
1086 - EAPOL/EAP functions
1089 * Initial version of wpa_supplicant
