1 ChangeLog for wpa_supplicant
4 * added support for EAP Sequences in EAP-FAST Phase 2
7 * removed 'nai' and 'eappsk' network configuration variables that were
8 previously used for configuring user identity and key for EAP-PSK,
9 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
10 replacement for 'nai' (if old configuration used a separate
11 'identity' value, that would now be configured as
12 'anonymous_identity'). 'password' field is now used as the
13 replacement for 'eappsk' (it can also be set using hexstring to
14 present random binary data)
15 * removed '-w' command line parameter (wait for interface to be added,
16 if needed); cleaner way of handling this functionality is to use an
17 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
18 when an interface is added
19 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
20 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
21 indicating when new scan results become available
22 * added new ctrl_iface command, BSS, to allow scan results to be
23 fetched without hitting the message size limits (this command
24 can be used to iterate through the scan results one BSS at the time)
25 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
26 attributes in EAP-SIM Start/Response when using fast reauthentication
27 * fixed EAPOL not to end up in infinite loop when processing dynamic
28 WEP keys with IEEE 802.1X
29 * fixed problems in getting NDIS events from WMI on Windows 2000
32 * added support for Makefile builds to include debug-log-to-a-file
33 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
34 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
35 lengths properly to avoid potential crash caused by invalid messages
36 * added data structure for storing allocated buffers (struct wpabuf);
37 this does not affect wpa_supplicant usage, but many of the APIs
38 changed and various interfaces (e.g., EAP) is not compatible with old
40 * added support for protecting EAP-AKA/Identity messages with
41 AT_CHECKCODE (optional feature in RFC 4187)
42 * added support for protected result indication with AT_RESULT_IND for
43 EAP-SIM and EAP-AKA (phase1="result_ind=1")
44 * added driver_wext workaround for race condition between scanning and
45 association with drivers that take very long time to scan all
46 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
47 using a longer hardcoded timeout for the scan if the driver supports
48 notifications for scan completion (SIOCGIWSCAN event); this helps,
49 e.g., in cases where wpa_supplicant and madwifi driver ended up in
50 loop where the driver did not even try to associate
51 * stop EAPOL timer tick when no timers are in use in order to reduce
52 power consumption (no need to wake up the process once per second)
54 * added support for privilege separation (run only minimal part of
55 wpa_supplicant functionality as root and rest as unprivileged,
56 non-root process); see 'Privilege separation' in README for details;
57 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
59 * changed scan results data structure to include all information
60 elements to make it easier to support new IEs; old get_scan_result()
61 driver_ops is still supported for backwards compatibility (results
62 are converted internally to the new format), but all drivers should
63 start using the new get_scan_results2() to make them more likely to
64 work with new features
65 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
66 application, i.e., it does not require Qt3Support anymore; Windows
67 binary of wpa_gui.exe is now from this directory and only requires
68 QtCore4.dll and QtGui4.dll libraries
69 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
70 available as a separate package to make wpa_gui installation easier:
71 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
72 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
73 only shared key/password authentication is supported in this version
76 * added support for configuring password as NtPasswordHash
77 (16-byte MD4 hash of password) in hash:<32 hex digits> format
78 * added support for fallback from abbreviated TLS handshake to
79 full handshake when using EAP-FAST (e.g., due to an expired
81 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
82 draft (draft-ietf-emu-eap-gpsk-07.txt)
83 * added support for drivers that take care of RSN 4-way handshake
84 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
85 WPA_ALG_PMK in set_key)
86 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
87 .config); this version supports only ap_scan=2 mode and allow the
88 driver to take care of the 4-way handshake
89 * fixed a buffer overflow in parsing TSF from scan results when using
90 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
92 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
93 * fixed an integer overflow issue in the ASN.1 parser used by the
94 (experimental) internal TLS implementation to avoid a potential
96 * fixed a race condition with -W option (wait for a control interface
97 monitor before starting) that could have caused the first messages to
99 * added support for processing TNCC-TNCS-Messages to report
100 recommendation (allow/none/isolate) when using TNC [Bug 243]
103 * added network configuration parameter 'frequency' for setting
104 initial channel for IBSS (adhoc) networks
105 * added experimental IEEE 802.11r/D6.0 support
106 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
107 * updated EAP-PSK to use the IANA-allocated EAP type 47
108 * fixed EAP-PAX key derivation
109 * fixed EAP-PSK bit ordering of the Flags field
110 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
111 tunnelled identity request (previously, the identifier from the outer
112 method was used, not the tunnelled identifier which could be
114 * added support for fragmentation of outer TLS packets during Phase 2
115 of EAP-PEAP/TTLS/FAST
116 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
117 * added support for EAP-FAST authentication with inner methods that
118 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
119 for PAC provisioning)
120 * added support for authenticated EAP-FAST provisioning
121 * added support for configuring maximum number of EAP-FAST PACs to
122 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
123 * added support for storing EAP-FAST PACs in binary format
124 (fast_pac_format=binary in phase1 string)
125 * fixed dbus ctrl_iface to validate message interface before
126 dispatching to avoid a possible segfault [Bug 190]
127 * fixed PeerKey key derivation to use the correct PRF label
128 * updated Windows binary build to link against OpenSSL 0.9.8d and
129 added support for EAP-FAST
130 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
131 draft (draft-ietf-emu-eap-gpsk-04.txt)
132 * fixed EAP-AKA Notification processing to allow Notification to be
133 processed after AKA Challenge response has been sent
134 * updated to use IEEE 802.11w/D2.0 for management frame protection
136 * fixed EAP-TTLS implementation not to crash on use of freed memory
137 if TLS library initialization fails
138 * added support for EAP-TNC (Trusted Network Connect)
139 (this version implements the EAP-TNC method and EAP-TTLS changes
140 needed to run two methods in sequence (IF-T) and the IF-IMC and
141 IF-TNCCS interfaces from TNCC)
144 * added experimental, integrated TLSv1 client implementation with the
145 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
146 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
147 .config); this can be useful, e.g., if the target system does not
148 have a suitable TLS library and a minimal code size is required
149 (total size of this internal TLS/crypto code is bit under 50 kB on
150 x86 and the crypto code is shared by rest of the supplicant so some
151 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
152 * removed STAKey handshake since PeerKey handshake has replaced it in
153 IEEE 802.11ma and there are no known deployments of STAKey
154 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
155 draft (draft-ietf-emu-eap-gpsk-01.txt)
156 * added preliminary implementation of IEEE 802.11w/D1.0 (management
158 (Note: this requires driver support to work properly.)
159 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
160 * fixed Windows named pipes ctrl_iface to not stop listening for
161 commands if client program opens a named pipe and closes it
162 immediately without sending a command
163 * fixed USIM PIN status determination for the case that PIN is not
164 needed (this allows EAP-AKA to be used with USIM cards that do not
166 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
167 be used with cards that do not support file selection based on
169 * added support for matching the subjectAltName of the authentication
170 server certificate against multiple name components (e.g.,
171 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
172 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
173 affects IEEE 802.1X with dynamic WEP keys)
174 * changed ctrl_iface network configuration 'get' operations to not
175 return password/key material; if these fields are requested, "*"
176 will be returned if the password/key is set, but the value of the
177 parameter is not exposed
180 * added support for building Windows version with UNICODE defined
181 (wide-char functions)
182 * driver_ndis: fixed static WEP configuration to avoid race condition
183 issues with some NDIS drivers between association and setting WEP
185 * driver_ndis: added validation for IELength value in scan results to
186 avoid crashes when using buggy NDIS drivers [Bug 165]
187 * fixed Release|Win32 target in the Visual Studio project files
188 (previously, only Debug|Win32 target was set properly)
189 * changed control interface API call wpa_ctrl_pending() to allow it to
190 return -1 on error (e.g., connection lost); control interface clients
191 will need to make sure that they verify that the value is indeed >0
192 when determining whether there are pending messages
193 * added an alternative control interface backend for Windows targets:
194 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
195 control interface mechanism for Windows builds (previously, UDP to
197 * changed ctrl_interface configuration for UNIX domain sockets:
198 - deprecated ctrl_interface_group variable (it may be removed in
200 - allow both directory and group be configured with ctrl_interface
201 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
202 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
203 case when group is not changed
204 * added support for controlling more than one interface per process in
206 * added a workaround for a case where the AP is using unknown address
207 (e.g., MAC address of the wired interface) as the source address for
208 EAPOL-Key frames; previously, that source address was used as the
209 destination for EAPOL-Key frames and in key derivation; now, BSSID is
210 used even if the source address does not match with it
211 (this resolves an interoperability issue with Thomson SpeedTouch 580)
212 * added a workaround for UDP-based control interface (which was used in
213 Windows builds before this release) to prevent packets with forged
214 addresses from being accepted as local control requests
215 * removed ndis_events.cpp and possibility of using external
216 ndis_events.exe; C version (ndis_events.c) is fully functional and
217 there is no desire to maintain two separate versions of this
219 * ndis_events: Changed NDIS event notification design to use WMI to
220 learn the adapter description through Win32_PnPEntity class; this
221 should fix some cases where the adapter name was not recognized
222 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
224 * fixed selection of the first network in ap_scan=2 mode; previously,
225 wpa_supplicant could get stuck in SCANNING state when only the first
226 network for enabled (e.g., after 'wpa_cli select_network 0')
227 * winsvc: added support for configuring ctrl_interface parameters in
228 registry (ctrl_interface string value in
229 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
230 required to enable control interface (previously, this was hardcoded
232 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
233 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
236 * fixed build with CONFIG_STAKEY=y [Bug 143]
237 * added support for doing MLME (IEEE 802.11 management frame
238 processing) in wpa_supplicant when using Devicescape IEEE 802.11
239 stack (wireless-dev.git tree)
240 * added a new network block configuration option, fragment_size, to
241 configure the maximum EAP fragment size
242 * driver_ndis: Disable WZC automatically for the selected interface to
243 avoid conflicts with two programs trying to control the radio; WZC
244 will be re-enabled (if it was enabled originally) when wpa_supplicant
246 * added an experimental TLSv1 client implementation
247 (CONFIG_TLS=internal) that can be used instead of an external TLS
248 library, e.g., to reduce total size requirement on systems that do
249 not include any TLS library by default (this is not yet complete;
250 basic functionality is there, but certificate validation is not yet
252 * added PeerKey handshake implementation for IEEE 802.11e
253 direct link setup (DLS) to replace STAKey handshake
254 * fixed WPA PSK update through ctrl_iface for the case where the old
255 PSK was derived from an ASCII passphrase and the new PSK is set as
256 a raw PSK (hex string)
257 * added new configuration option for identifying which network block
258 was used (id_str in wpa_supplicant.conf; included on
259 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
260 variable in wpa_cli action scripts; in addition WPA_ID variable is
261 set to the current unique identifier that wpa_supplicant assigned
262 automatically for the network and that can be used with
263 GET_NETWORK/SET_NETWORK ctrl_iface commands)
264 * wpa_cli action script is now called only when the connect/disconnect
265 status changes or when associating with a different network
266 * fixed configuration parser not to remove CCMP from group cipher list
267 if WPA-None (adhoc) is used (pairwise=NONE in that case)
268 * fixed integrated NDIS events processing not to hang the process due
269 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
270 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
271 draft-clancy-emu-eap-shared-secret-00.txt)
272 * added Microsoft Visual Studio 2005 solution and project files for
273 build wpa_supplicant for Windows (see vs2005 subdirectory)
274 * eloop_win: fixed unregistration of Windows events
275 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
276 at the end of RSN pre-authentication and added unregistration of
277 a Windows event to avoid getting eloop_win stuck with an invalid
279 * driver_ndis: added support for selecting AP based on BSSID
280 * added new environmental variable for wpa_cli action scripts:
281 WPA_CTRL_DIR is the current control interface directory
282 * driver_ndis: added support for using NDISUIO instead of WinPcap for
283 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
284 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
285 wpa_supplicant without requiring WinPcap; note that using NDISUIO
286 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
287 only one application to open the device
288 * changed NDIS driver naming to only include device GUID, e.g.,
289 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
290 specific \Device\NPF_ prefix before the GUID; the prefix is still
291 allowed for backwards compatibility, but it is not required anymore
292 when specifying the interface
293 * driver_ndis: re-initialize driver interface is the adapter is removed
294 and re-inserted [Bug 159]
295 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
296 big endian hosts [Bug 146]
299 * fixed EAP-GTC response to include correct user identity when run as
300 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
301 * driver_ndis: Fixed encryption mode configuration for unencrypted
302 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
303 refused to associate with open networks) [Bug 106]
304 * driver_ndis: use BSSID OID polling to detect when IBSS network is
305 formed even when ndis_events code is included since some NDIS drivers
306 do not generate media connect events in IBSS mode
307 * config_winreg: allow global ctrl_interface parameter to be configured
309 * config_winreg: added support for saving configuration data into
311 * added support for controlling network device operational state
312 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
313 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
314 that can use this information)
315 * driver_wext: added support for WE-21 change to SSID configuration
316 * driver_wext: fixed privacy configuration for static WEP keys mode
318 * added an optional driver_ops callback for MLME-SETPROTECTION.request
320 * added support for EAP-SAKE (no EAP method number allocated yet, so
321 this is using the same experimental type 255 as EAP-PSK)
322 * added support for dynamically loading EAP methods (.so files) instead
323 of requiring them to be statically linked in; this is disabled by
324 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
328 * do not try to use USIM APDUs when initializing PC/SC for SIM card
329 access for a network that has not enabled EAP-AKA
330 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
331 v0.5.1 due to the new support for expanded EAP types)
332 * added support for generating EAP Expanded Nak
333 * try to fetch scan results once before requesting new scan when
334 starting up in ap_scan=1 mode (this can speed up initial association
335 a lot with, e.g., madwifi-ng driver)
336 * added support for receiving EAPOL frames from a Linux bridge
337 interface (-bbr0 on command line)
338 * fixed EAPOL re-authentication for sessions that used PMKSA caching
339 * changed EAP method registration to use a dynamic list of methods
340 instead of a static list generated at build time
341 * fixed PMKSA cache deinitialization not to use freed memory when
342 removing PMKSA entries
343 * fixed a memory leak in EAP-TTLS re-authentication
344 * reject WPA/WPA2 message 3/4 if it does not include any valid
346 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
347 if the driver does not support SIOCSIWAUTH
350 * driver_test: added better support for multiple APs and STAs by using
351 a directory with sockets that include MAC address for each device in
352 the name (driver_param=test_dir=/tmp/test)
353 * added support for EAP expanded type (vendor specific EAP methods)
354 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
355 option can be changed if needed
356 * wpa_cli/wpa_gui: skip non-socket files in control directory when
357 using UNIX domain sockets; this avoids selecting an incorrect
358 interface (e.g., a PID file could be in this directory, even though
359 use of this directory for something else than socket files is not
361 * fixed TLS library deinitialization after RSN pre-authentication not
362 to disable TLS library for normal authentication
363 * driver_wext: Remove null-termination from SSID length if the driver
364 used it; some Linux drivers do this and they were causing problems in
365 wpa_supplicant not finding matching configuration block. This change
366 would break a case where the SSID actually ends in '\0', but that is
367 not likely to happen in real use.
368 * fixed PMKSA cache processing not to trigger deauthentication if the
369 current PMKSA cache entry is replaced with a valid new entry
370 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
371 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
374 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
375 * added experimental STAKey handshake implementation for IEEE 802.11e
376 direct link setup (DLS); note: this is disabled by default in both
377 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
379 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
380 decrypt AT_ENCR_DATA attributes correctly
381 * fixed EAP-AKA to allow resynchronization within the same session
382 * made code closer to ANSI C89 standard to make it easier to port to
383 other C libraries and compilers
384 * started moving operating system or C library specific functions into
385 wrapper functions defined in os.h and implemented in os_*.c to make
387 * wpa_supplicant can now be built with Microsoft Visual C++
388 (e.g., with the freely available Toolkit 2003 version or Visual
389 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
390 example makefile for nmake
391 * added support for using Windows registry for command line parameters
392 (CONFIG_MAIN=main_winsvc) and configuration data
393 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
394 contents; this version can be run both as a Windows service and as a
395 normal application; 'wpasvc.exe app' to start as applicant,
396 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
397 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
399 * made it possible to link ndis_events.exe functionality into
400 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
401 * added better support for multiple control interface backends
402 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
403 * fixed PC/SC code to use correct length for GSM AUTH command buffer
404 and to not use pioRecvPci with SCardTransmit() calls; these were not
405 causing visible problems with pcsc-lite, but Windows Winscard.dll
406 refused the previously used parameters; this fixes EAP-SIM and
407 EAP-AKA authentication using SIM/USIM card under Windows
408 * added new event loop implementation for Windows using
409 WaitForMultipleObject() instead of select() in order to allow waiting
410 for non-socket objects; this can be selected with
411 CONFIG_ELOOP=eloop_win in .config
412 * added support for selecting l2_packet implementation in .config
413 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
414 winpcap, freebsd, none)
415 * added new l2_packet implementation for WinPcap
416 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
417 reduce latency in EAPOL receive processing from about 100 ms to about
419 * added support for EAP-FAST key derivation using other ciphers than
420 RC4-128-SHA for authentication and AES128-SHA for provisioning
421 * added support for configuring CA certificate as DER file and as a
423 * fixed private key configuration as configuration blob and added
424 support for using PKCS#12 as a blob
425 * tls_gnutls: added support for using PKCS#12 files; added support for
427 * added support for loading trusted CA certificates from Windows
428 certificate store: ca_cert="cert_store://<name>", where <name> is
429 likely CA (Intermediate CA certificates) or ROOT (root certificates)
430 * added C version of ndis_events.cpp and made it possible to build this
431 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
432 easily on cross-compilation builds
433 * added wpasvc.exe into Windows binary release; this is an alternative
434 version of wpa_supplicant.exe with configuration backend using
435 Windows registry and with the entry point designed to run as a
437 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
438 wpasvc.exe and removed this additional tool from the Windows binary
439 release since it is not needed anymore
440 * load winscard.dll functions dynamically when building with MinGW
441 since MinGW does not yet include winscard library
443 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
444 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
445 and WinPcap to receive frames sent to PAE group address
446 * disable EAP state machine when IEEE 802.1X authentication is not used
447 in order to get rid of bogus "EAP failed" messages
448 * fixed OpenSSL error reporting to go through all pending errors to
449 avoid confusing reports of old errors being reported at later point
451 * fixed configuration file updating to not write empty variables
452 (e.g., proto or key_mgmt) that the file parser would not accept
453 * fixed ADD_NETWORK ctrl_iface command to use the same default values
454 for variables as empty network definitions read from config file
456 * fixed EAP state machine to not discard EAP-Failure messages in many
457 cases (e.g., during TLS handshake)
458 * fixed a infinite loop in private key reading if the configured file
459 cannot be parsed successfully
460 * driver_madwifi: added support for madwifi-ng
461 * wpa_gui: do not display password/PSK field contents
462 * wpa_gui: added CA certificate configuration
463 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
464 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
465 the new AP is using different WPA/RSN IE
466 * use longer timeout for IEEE 802.11 association to avoid problems with
467 drivers that may take more than five second to associate
470 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
471 RSN IE, but WPA IE would match with wpa_supplicant configuration
472 * added support for named configuration blobs in order to avoid having
473 to use file system for external files (e.g., certificates);
474 variables can be set to "blob://<blob name>" instead of file path to
475 use a named blob; supported fields: pac_file, client_cert,
477 * fixed RSN pre-authentication (it was broken in the clean up of WPA
478 state machine interface in v0.4.5)
479 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
480 sure the driver configures broadcast decryption correctly
481 * added ca_path (and ca_path2) configuration variables that can be used
482 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
483 system-wide trusted CA list
484 * added support for starting wpa_supplicant without a configuration
485 file (-C argument must be used to set ctrl_interface parameter for
486 this case; in addition, -p argument can be used to provide
487 driver_param; these new arguments can also be used with a
488 configuration to override the values from the configuration)
489 * added global control interface that can be optionally used for adding
490 and removing network interfaces dynamically (-g command line argument
491 for both wpa_supplicant and wpa_cli) without having to restart
492 wpa_supplicant process
494 - try to save configuration whenever something is modified
495 - added WEP key configuration
496 - added possibility to edit the current network configuration
497 * driver_ndis: fixed driver polling not to increase frequency on each
498 received EAPOL frame due to incorrectly cancelled timeout
499 * added simple configuration file examples (in examples subdirectory)
500 * fixed driver_wext.c to filter wireless events based on ifindex to
501 avoid interfaces receiving events from other interfaces
502 * delay sending initial EAPOL-Start couple of seconds to speed up
503 authentication for the most common case of Authenticator starting
504 EAP authentication immediately after association
507 * added a workaround for clearing keys with ndiswrapper to allow
508 roaming from WPA enabled AP to plaintext one
509 * added docbook documentation (doc/docbook) that can be used to
510 generate, e.g., man pages
511 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
512 PF_PACKET in order to prepare for network devices that do not use
513 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
514 * use receipt of EAPOL-Key frame as a lower layer success indication
515 for EAP state machine to allow recovery from dropped EAP-Success
517 * cleaned up internal EAPOL frame processing by not including link
518 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
519 header is added only when transmitted the frame; this makes it easier
520 to use wpa_supplicant on link layers that use different header than
522 * updated EAP-PSK to use draft 9 by default since this can now be
523 tested with hostapd; removed support for draft 3, including
524 server_nai configuration option from network blocks
525 * driver_wired: add PAE address to the multicast address list in order
526 to be able to receive EAPOL frames with drivers that do not include
527 these multicast addresses by default
528 * driver_wext: add support for WE-19
529 * added support for multiple configuration backends (CONFIG_BACKEND
530 option); currently, only 'file' is supported (i.e., the format used
531 in wpa_supplicant.conf)
532 * added support for updating configuration ('wpa_cli save_config');
533 this is disabled by default and can be enabled with global
534 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
535 and wpa_gui to store the configuration changes in a permanent store
536 * added GET_NETWORK ctrl_iface command
537 (e.g., 'wpa_cli get_network 0 ssid')
540 * replaced OpenSSL patch for EAP-FAST support
541 (openssl-tls-extensions.patch) with a more generic and correct
542 patch (the new patch is not compatible with the previous one, so the
543 OpenSSL library will need to be patched with the new patch in order
544 to be able to build wpa_supplicant with EAP-FAST support)
545 * added support for using Windows certificate store (through CryptoAPI)
546 for client certificate and private key operations (EAP-TLS)
547 (see wpa_supplicant.conf for more information on how to configure
548 this with private_key)
549 * ported wpa_gui to Windows
550 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
551 built with the open source version of the Qt4 for Windows
552 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
553 with drivers that do not support WPA
554 * ndis_events: fixed Windows 2000 support
555 * added support for enabling/disabling networks from the list of all
556 configured networks ('wpa_cli enable_network <network id>' and
557 'wpa_cli disable_network <network id>')
558 * added support for adding and removing network from the current
559 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
560 <network id>'); added networks are disabled by default and they can
561 be enabled with enable_network command once the configuration is done
562 for the new network; note: configuration file is not yet updated, so
563 these new networks are lost when wpa_supplicant is restarted
564 * added support for setting network configuration parameters through
565 the control interface, for example:
566 wpa_cli set_network 0 ssid "\"my network\""
567 * fixed parsing of strings that include both " and # within double
568 quoted area (e.g., "start"#end")
569 * added EAP workaround for PEAP session resumption: allow outer,
570 i.e., not tunneled, EAP-Success to terminate session since; this can
571 be disabled with eap_workaround=0
572 (this was allowed for PEAPv1 before, but now it is also allowed for
573 PEAPv0 since at least one RADIUS authentication server seems to be
574 doing this for PEAPv0, too)
575 * wpa_gui: added preliminary support for adding new networks to the
576 wpa_supplicant configuration (double click on the scan results to
577 open network configuration)
580 * removed interface for external EAPOL/EAP supplicant (e.g.,
581 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
582 anymore and is unlikely to be used by anyone
583 * driver_ndis: fixed WinPcap 3.0 support
584 * fixed build with CONFIG_DNET_PCAP=y on Linux
585 * l2_packet: moved different implementations into separate files
589 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
590 (note: ipw2100-1.1.0 is likely to require an update to work with
592 * added support for using ap_scan=2 mode with multiple network blocks;
593 wpa_supplicant will go through the networks one by one until the
594 driver reports a successful association; this uses the same order for
595 networks as scan_ssid=1 scans, i.e., the priority field is ignored
596 and the network block order in the file is used instead
597 * fixed a potential issue in RSN pre-authentication ending up using
598 freed memory if pre-authentication times out
599 * added support for matching alternative subject name extensions of the
600 authentication server certificate; new configuration variables
601 altsubject_match and altsubject_match2
602 * driver_ndis: added support for IEEE 802.1X authentication with wired
604 * added support for querying private key password (EAP-TLS) through the
605 control interface (wpa_cli/wpa_gui) if one is not included in the
607 * driver_broadcom: fixed couple of memory leaks in scan result
609 * EAP-PAX is now registered as EAP type 46
610 * fixed EAP-PAX MAC calculation
611 * fixed EAP-PAX CK and ICK key derivation
612 * added support for using password with EAP-PAX (as an alternative to
613 entering key with eappsk); SHA-1 hash of the password will be used as
615 * added support for arbitrary driver interface parameters through the
616 configuration file with a new driver_param field; this adds a new
617 driver_ops function set_param()
618 * added possibility to override l2_packet module with driver interface
619 API (new send_eapol handler); this can be used to implement driver
620 specific TX/RX functions for EAPOL frames
621 * fixed ctrl_interface_group processing for the case where gid is
622 entered as a number, not group name
623 * driver_test: added support for testing hostapd with wpa_supplicant
624 by using test driver interface without any kernel drivers or network
628 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
629 packets to be encrypted; this was apparently broken by the changed
630 ioctl order in v0.4.0
631 * driver_madwifi: added preliminary support for compiling against 'BSD'
632 branch of madwifi CVS tree
633 * added support for EAP-MSCHAPv2 password retries within the same EAP
634 authentication session
635 * added support for password changes with EAP-MSCHAPv2 (used when the
636 password has expired)
637 * added support for reading additional certificates from PKCS#12 files
638 and adding them to the certificate chain
639 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
641 * fixed a possible double free in EAP-TTLS fast-reauthentication when
642 identity or password is entered through control interface
643 * display EAP Notification messages to user through control interface
644 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
645 * added GUI version of wpa_cli, wpa_gui; this is not build
646 automatically with 'make'; use 'make wpa_gui' to build (this requires
647 Qt development tools)
648 * added 'disconnect' command to control interface for setting
649 wpa_supplicant in state where it will not associate before
650 'reassociate' command has been used
651 * added support for selecting a network from the list of all configured
652 networks ('wpa_cli select_network <network id>'; this disabled all
653 other networks; to re-enable, 'wpa_cli select_network any')
654 * added support for getting scan results through control interface
655 * added EAP workaround for PEAPv1 session resumption: allow outer,
656 i.e., not tunneled, EAP-Success to terminate session since; this can
657 be disabled with eap_workaround=0
659 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
660 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
661 used to reduce the size of the wpa_supplicant considerably if
662 debugging code is not needed
663 * fixed EAPOL-Key validation to drop packets with invalid Key Data
664 Length; such frames could have crashed wpa_supplicant due to buffer
666 * added support for wired authentication (IEEE 802.1X on wired
667 Ethernet); driver interface 'wired'
668 * obsoleted set_wpa() handler in the driver interface API (it can be
669 replaced by moving enable/disable functionality into init()/deinit())
670 (calls to set_wpa() are still present for backwards compatibility,
671 but they may be removed in the future)
672 * driver_madwifi: fixed association in plaintext mode
673 * modified the EAP workaround that accepts EAP-Success with incorrect
674 Identifier to be even less strict about verification in order to
675 interoperate with some authentication servers
676 * added support for sending TLS alerts
677 * added support for 'any' SSID wildcard; if ssid is not configured or
678 is set to an empty string, any SSID will be accepted for non-WPA AP
679 * added support for asking PIN (for SIM) from frontends (e.g.,
680 wpa_cli); if a PIN is needed, but not included in the configuration
681 file, a control interface request is sent and EAP processing is
682 delayed until the PIN is available
683 * added support for using external devices (e.g., a smartcard) for
684 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
685 new wpa_supplicant.conf variables:
686 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
687 - network: engine, engine_id, key_id
688 * added experimental support for EAP-PAX
689 * added monitor mode for wpa_cli (-a<path to a program to run>) that
690 allows external commands (e.g., shell scripts) to be run based on
691 wpa_supplicant events, e.g., when authentication has been completed
692 and data connection is ready; other related wpa_cli arguments:
693 -B (run in background), -P (write PID file); wpa_supplicant has a new
694 command line argument (-W) that can be used to make it wait until a
695 control interface command is received in order to avoid missing
697 * added support for opportunistic WPA2 PMKSA key caching (disabled by
698 default, can be enabled with proactive_key_caching=1)
699 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
700 Authenticator rejects PMKSA caching attempt and the driver is not
701 using assoc_info events
702 * added -P<pid file> argument for wpa_supplicant to write the current
703 process id into a file
705 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
706 * added new phase1 option parameter, include_tls_length=1, to force
707 wpa_supplicant to add TLS Message Length field to all TLS messages
708 even if the packet is not fragmented; this may be needed with some
709 authentication servers
710 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
711 using drivers that take care of AP selection (e.g., when using
713 * fixed reprocessing of pending request after ctrl_iface requests for
714 identity/password/otp
715 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
716 EAP-PEAP and EAP-TTLS
717 * all drivers using driver_wext: set interface up and select Managed
718 mode when starting wpa_supplicant; set interface down when exiting
719 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
720 ipw2100 and ipw2200; please note that this also changed the
721 configuration variable in .config to CONFIG_DRIVER_IPW
724 * fixed a busy loop introduced in v0.3.5 for scan result processing
725 when no matching AP is found
728 * added a workaround for an interoperability issue with a Cisco AP
730 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
731 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
732 retransmission of dropped frames)
733 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
734 (e.g., segfault when processing EAPOL-Key frames)
735 * fixed EAP workaround and fast reauthentication configuration for
736 RSN pre-authentication; previously these were disabled and
737 pre-authentication would fail if the used authentication server
738 requires EAP workarounds
739 * added support for blacklisting APs that fail or timeout
740 authentication in ap_scan=1 mode so that all APs are tried in cases
741 where the ones with strongest signal level are failing authentication
742 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
743 authentication attempt
744 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
745 in the previous authentication (previously, only Phase 1 success was
749 * added preliminary support for IBSS (ad-hoc) mode configuration
750 (mode=1 in network block); this included a new key_mgmt mode
751 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
752 key management; see wpa_supplicant.conf for more details and an
753 example on how to configure this (note: this is currently implemented
754 only for driver_hostapd.c, but the changes should be trivial to add
755 in associate() handler for other drivers, too (assuming the driver
757 * added preliminary port for native Windows (i.e., no cygwin) using
761 * added optional support for GNU Readline and History Libraries for
762 wpa_cli (CONFIG_READLINE)
763 * cleaned up EAP state machine <-> method interface and number of
764 small problems with error case processing not terminating on
765 EAP-Failure but waiting for timeout
766 * added couple of workarounds for interoperability issues with a
767 Cisco AP when using WPA2
768 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
769 Note: This requires a patch for openssl to add support for TLS
770 extensions and number of workarounds for operations without
771 certificates. Proof of concept type of experimental patch is
772 included in openssl-tls-extensions.patch.
775 * fixed private key loading for cases where passphrase is not set
776 * fixed Windows/cygwin L2 packet handler freeing; previous version
777 could cause a segfault when RSN pre-authentication was completed
778 * added support for PMKSA caching with drivers that generate RSN IEs
779 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
780 but similar code can be easily added to driver_ndiswrapper.c once
781 ndiswrapper gets full support for RSN PMKSA caching
782 * improved recovery from PMKID mismatches by requesting full EAP
783 authentication in case of failed PMKSA caching attempt
784 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
785 (this requires that ndis_events is ran while wpa_supplicant is
787 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
788 * added support for driver interfaces to replace the interface name
789 based on driver/OS specific mapping, e.g., in case of driver_ndis,
790 this allows the beginning of the adapter description to be used as
792 * added support for CR+LF (Windows-style) line ends in configuration
794 * driver_ndis: enable radio before starting scanning, disable radio
796 * modified association event handler to set portEnabled = FALSE before
797 clearing port Valid in order to reset EAP state machine and avoid
798 problems with new authentication getting ignored because of state
799 machines ending up in AUTHENTICATED/SUCCESS state based on old
801 * added support for driver events to add PMKID candidates in order to
802 allow drivers to give priority to most likely roaming candidates
803 * driver_hostap: moved PrivacyInvoked configuration to associate()
804 function so that this will not be set for plaintext connections
805 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
806 interface can distinguish plaintext and IEEE 802.1X (no WPA)
808 * fixed static WEP key configuration to use broadcast/default type for
809 all keys (previously, the default TX key was configured as pairwise/
811 * driver_ndis: added legacy WPA capability detection for non-WPA2
813 * added support for setting static WEP keys for IEEE 802.1X without
814 dynamic WEP keying (eapol_flags=0)
817 * added support for reading PKCS#12 (PFX) files (as a replacement for
818 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
819 * fixed compilation with CONFIG_PCSC=y
820 * added new ap_scan mode, ap_scan=2, for drivers that take care of
821 association, but need to be configured with security policy and SSID,
822 e.g., ndiswrapper and NDIS driver; this mode should allow such
823 drivers to work with hidden SSIDs and optimized roaming; when
824 ap_scan=2 is used, only the first network block in the configuration
825 file is used and this configuration should have explicit security
826 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
827 group, proto variables
828 * added experimental port of wpa_supplicant for Windows
829 - driver_ndis.c driver interface (NDIS OIDs)
830 - currently, this requires cygwin and WinPcap
831 - small utility, win_if_list, can be used to get interface name
832 * control interface can now be removed at build time; add
833 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
834 * optional Xsupplicant interface can now be removed at build time;
835 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
836 * added auth_alg to driver interface associate() parameters to make it
837 easier for drivers to configure authentication algorithm as part of
840 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
841 * driver_broadcom: added new driver interface for Broadcom wl.o driver
842 (a generic driver for Broadcom IEEE 802.11a/g cards)
843 * wpa_cli: fixed parsing of -p <path> command line argument
844 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
845 ACK, not tunneled EAP-Success (of which only the first byte was
846 actually send due to a bug in previous code); this seems to
847 interoperate with most RADIUS servers that implements PEAPv1
848 * PEAPv1: added support for terminating PEAP authentication on tunneled
849 EAP-Success message; this can be configured by adding
850 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
851 (some RADIUS servers require this whereas others require a tunneled
853 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
854 the old label for key derivation; previously, the default was 1,
855 but it looks like most existing PEAPv1 implementations use the old
856 label which is thus more suitable default option
857 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
858 * fixed parsing of wep_tx_keyidx
859 * added support for configuring list of allowed Phase 2 EAP types
860 (for both EAP-PEAP and EAP-TTLS) instead of only one type
861 * added support for configuring IEEE 802.11 authentication algorithm
862 (auth_alg; mainly for using Shared Key authentication with static
864 * added support for EAP-AKA (with UMTS SIM)
865 * fixed couple of errors in PCSC handling that could have caused
866 random-looking errors for EAP-SIM
867 * added support for EAP-SIM pseudonyms and fast re-authentication
868 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
870 * added support for EAP-SIM with two challanges
871 (phase1="sim_min_num_chal=3" can be used to require three challenges)
872 * added support for configuring DH/DSA parameters for an ephemeral DH
873 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
874 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
875 and optional DH key exchange to achieve forward secracy with RSA keys
876 * added support for matching subject of the authentication server
877 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
878 configuration variables subject_match and subject_match2
879 * changed SSID configuration in driver_wext.c (used by many driver
880 interfaces) to use ssid_len+1 as the length for SSID since some Linux
882 * fixed couple of unaligned reads in scan result parsing to fix WPA
883 connection on some platforms (e.g., ARM)
884 * added driver interface for Intel ipw2100 driver
885 * added support for LEAP with WPA
886 * added support for larger scan results report (old limit was 4 kB of
887 data, i.e., about 35 or so APs) when using Linux wireless extensions
889 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
890 only if there is a PMKSA cache entry for the current AP
891 * fixed error handling for case where reading of scan results fails:
892 must schedule a new scan or wpa_supplicant will remain waiting
894 * changed debug output to remove shared password/key material by
895 default; all key information can be included with -K command line
896 argument to match the previous behavior
897 * added support for timestamping debug log messages (disabled by
898 default, can be enabled with -t command line argument)
899 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
900 if keys are not configured to be used; this fixes IEEE 802.1X mode
901 with drivers that use this information to configure whether Privacy
902 bit can be in Beacon frames (e.g., ndiswrapper)
903 * avoid clearing driver keys if no keys have been configured since last
904 key clear request; this seems to improve reliability of group key
905 handshake for ndiswrapper & NDIS driver which seems to be suffering
906 of some kind of timing issue when the keys are cleared again after
908 * changed driver interface API:
909 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
910 version is being used (now, this is set to 2; previously, it was
912 - pass pointer to private data structure to all calls
913 - the new API is not backwards compatible; all in-tree driver
914 interfaces has been converted to the new API
915 * added support for controlling multiple interfaces (radios) per
916 wpa_supplicant process; each interface needs to be listed on the
917 command line (-c, -i, -D arguments) with -N as a separator
918 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
919 * added a workaround for EAP servers that incorrectly use same Id for
920 sequential EAP packets
921 * changed libpcap/libdnet configuration to use .config variable,
922 CONFIG_DNET_PCAP, instead of requiring Makefile modification
923 * improved downgrade attack detection in IE verification of msg 3/4:
924 verify both WPA and RSN IEs, if present, not only the selected one;
925 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
926 Probe Response frame, and RSN is enabled in wpa_supplicant
928 * fixed WPA msg 3/4 processing to allow Key Data field contain other
929 IEs than just one WPA IE
930 * added support for FreeBSD and driver interface for the BSD net80211
931 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
932 required kernel mods have not yet been committed
933 * made EAP workarounds configurable; enabled by default, can be
934 disabled with network block option eap_workaround=0
936 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
937 * resolved couple of interoperability issues with EAP-PEAPv1 and
938 Phase 2 (inner EAP) fragment reassembly
939 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
940 AP is using non-zero key index for the unicast key and key index zero
941 for the broadcast key
942 * driver_hostap: fixed IEEE 802.1X WEP key updates and
943 re-authentication by allowing unencrypted EAPOL frames when not using
945 * added a new driver interface, 'wext', which uses only standard,
946 driver independent functionality in Linux wireless extensions;
947 currently, this can be used only for non-WPA IEEE 802.1X mode, but
948 eventually, this is to be extended to support full WPA/WPA2 once
949 Linux wireless extensions get support for this
950 * added support for mode in which the driver is responsible for AP
951 scanning and selection; this is disabled by default and can be
952 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
953 this mode can be used, e.g., with generic 'wext' driver interface to
954 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
955 supporting wireless extensions.
956 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
957 operation with an AP that does not include SSID in the Beacon frames)
958 * added support for new EAP authentication methods:
959 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
960 * added support for asking one-time-passwords from frontends (e.g.,
961 wpa_cli); this 'otp' command works otherwise like 'password' command,
962 but the password is used only once and the frontend will be asked for
963 a new password whenever a request from authenticator requires a
964 password; this can be used with both EAP-OTP and EAP-GTC
965 * changed wpa_cli to automatically re-establish connection so that it
966 does not need to be re-started when wpa_supplicant is terminated and
968 * improved user data (identity/password/otp) requests through
969 frontends: process pending EAPOL packets after getting new
970 information so that full authentication does not need to be
971 restarted; in addition, send pending requests again whenever a new
973 * changed control frontends to use a new directory for socket files to
974 make it easier for wpa_cli to automatically select between interfaces
975 and to provide access control for the control interface;
976 wpa_supplicant.conf: ctrl_interface is now a path
977 (/var/run/wpa_supplicant is the recommended path) and
978 ctrl_interface_group can be used to select which group gets access to
979 the control interface;
980 wpa_cli: by default, try to connect to the first interface available
981 in /var/run/wpa_supplicant; this path can be overriden with -p option
982 and an interface can be selected with -i option (i.e., in most common
983 cases, wpa_cli does not need to get any arguments)
984 * added support for LEAP
985 * added driver interface for Linux ndiswrapper
986 * added priority option for network blocks in the configuration file;
987 this allows networks to be grouped based on priority (the scan
988 results are searched for matches with network blocks in this order)
991 * sort scan results to improve AP selection
992 * fixed control interface socket removal for some error cases
993 * improved scan requesting and authentication timeout
994 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
996 * PEAP version can now be forced with phase1="peapver=<ver>"
997 (mostly for testing; by default, the highest version supported by
998 both the Supplicant and Authentication Server is selected
1000 * added support for madwifi driver (Atheros ar521x)
1001 * added a workaround for cases where AP sets Install Tx/Rx bit for
1002 WPA Group Key messages when pairwise keys are used (without this,
1003 the Group Key would be used for Tx and the AP would drop frames
1005 * added GSM SIM/USIM interface for GSM authentication algorithm for
1006 EAP-SIM; this requires pcsc-lite
1007 * added support for ATMEL AT76C5XXx driver
1008 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1009 does not include key data in the EAPOL-Key frame (i.e., part of
1010 EAP keying material is used as data encryption key)
1011 * added support for using plaintext and static WEP networks
1015 * added support for new EAP authentication methods:
1016 EAP-TTLS/EAP-MD5-Challenge
1018 EAP-TTLS/EAP-MSCHAPv2
1026 EAP-PEAP/MD5-Challenge
1028 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1029 * added support for anonymous identity (to be used when identity is
1030 sent in plaintext; real identity will be used within TLS protected
1031 tunnel (e.g., with EAP-TTLS)
1032 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1033 * added support for requesting identity and password information using
1034 control interface; in other words, the password for EAP-PEAP or
1035 EAP-TTLS does not need to be included in the configuration file since
1036 a frontand (e.g., wpa_cli) can ask it from the user
1037 * improved RSN pre-authentication to use a candidate list and process
1038 all candidates from each scan; not only one per scan
1039 * fixed RSN IE and WPA IE capabilities field parsing
1040 * ignore Tx bit in GTK IE when Pairwise keys are used
1041 * avoid making new scan requests during IEEE 802.1X negotiation
1042 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1043 with TLS support (this replaces the included implementation with
1044 library code to save about 8 kB since the library code is needed
1046 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1047 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1050 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1052 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1053 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1054 - EAP-MD5 (cannot be used with WPA-RADIUS)
1055 [draft-ietf-eap-rfc2284bis-09.txt]
1056 - EAP-TLS [RFC 2716]
1057 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1058 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1059 [draft-kamath-pppext-eap-mschapv2-00.txt]
1060 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1061 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1062 - new configuration file options: eap, identity, password, ca_cert,
1063 client_cert, privatekey, private_key_passwd
1064 - Xsupplicant is not required anymore, but it can be used by
1065 disabling the internal IEEE 802.1X Supplicant with -e command line
1067 - this code is not included in the default build; Makefile need to
1068 be edited for this (uncomment lines for selected functionality)
1069 - EAP-TLS and EAP-PEAP require openssl libraries
1070 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1071 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1072 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1073 EAPOL-Key frames instead of WPA key handshakes)
1074 * added support for IEEE 802.11i/RSN (WPA2)
1075 - improved PTK Key Handshake
1076 - PMKSA caching, pre-authentication
1077 * fixed wpa_supplicant to ignore possible extra data after WPA
1078 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1079 TPTK' error from message 3 of 4-Way Handshake in case the AP
1080 includes extra data after the EAPOL-Key)
1081 * added interface for external programs (frontends) to control
1083 - CLI example (wpa_cli) with interactive mode and command line
1085 - replaced SIGUSR1 status/statistics with the new control interface
1086 * made some feature compile time configurable
1087 - .config file for make
1088 - driver interfaces (hostap, hermes, ..)
1089 - EAPOL/EAP functions
1092 * Initial version of wpa_supplicant
