1 ChangeLog for wpa_supplicant
4 * added support for EAP Sequences in EAP-FAST Phase 2
5 * added support for using TNC with EAP-FAST
6 * added driver_ps3 for the PS3 Linux wireless driver
7 * added support for optional cryptobinding with PEAPv0
8 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
9 allow fallback to full handshake if server rejects PAC-Opaque
10 * added fragmentation support for EAP-TNC
11 * added support for parsing PKCS #8 formatted private keys into the
12 internal TLS implementation (both PKCS #1 RSA key and PKCS #8
13 encapsulated RSA key can now be used)
14 * added option of using faster, but larger, routines in the internal
15 LibTomMath (for internal TLS implementation) to speed up DH and RSA
16 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
19 * removed 'nai' and 'eappsk' network configuration variables that were
20 previously used for configuring user identity and key for EAP-PSK,
21 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
22 replacement for 'nai' (if old configuration used a separate
23 'identity' value, that would now be configured as
24 'anonymous_identity'). 'password' field is now used as the
25 replacement for 'eappsk' (it can also be set using hexstring to
26 present random binary data)
27 * removed '-w' command line parameter (wait for interface to be added,
28 if needed); cleaner way of handling this functionality is to use an
29 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
30 when an interface is added
31 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
32 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
33 indicating when new scan results become available
34 * added new ctrl_iface command, BSS, to allow scan results to be
35 fetched without hitting the message size limits (this command
36 can be used to iterate through the scan results one BSS at the time)
37 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
38 attributes in EAP-SIM Start/Response when using fast reauthentication
39 * fixed EAPOL not to end up in infinite loop when processing dynamic
40 WEP keys with IEEE 802.1X
41 * fixed problems in getting NDIS events from WMI on Windows 2000
44 * added support for Makefile builds to include debug-log-to-a-file
45 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
46 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
47 lengths properly to avoid potential crash caused by invalid messages
48 * added data structure for storing allocated buffers (struct wpabuf);
49 this does not affect wpa_supplicant usage, but many of the APIs
50 changed and various interfaces (e.g., EAP) is not compatible with old
52 * added support for protecting EAP-AKA/Identity messages with
53 AT_CHECKCODE (optional feature in RFC 4187)
54 * added support for protected result indication with AT_RESULT_IND for
55 EAP-SIM and EAP-AKA (phase1="result_ind=1")
56 * added driver_wext workaround for race condition between scanning and
57 association with drivers that take very long time to scan all
58 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
59 using a longer hardcoded timeout for the scan if the driver supports
60 notifications for scan completion (SIOCGIWSCAN event); this helps,
61 e.g., in cases where wpa_supplicant and madwifi driver ended up in
62 loop where the driver did not even try to associate
63 * stop EAPOL timer tick when no timers are in use in order to reduce
64 power consumption (no need to wake up the process once per second)
66 * added support for privilege separation (run only minimal part of
67 wpa_supplicant functionality as root and rest as unprivileged,
68 non-root process); see 'Privilege separation' in README for details;
69 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
71 * changed scan results data structure to include all information
72 elements to make it easier to support new IEs; old get_scan_result()
73 driver_ops is still supported for backwards compatibility (results
74 are converted internally to the new format), but all drivers should
75 start using the new get_scan_results2() to make them more likely to
76 work with new features
77 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
78 application, i.e., it does not require Qt3Support anymore; Windows
79 binary of wpa_gui.exe is now from this directory and only requires
80 QtCore4.dll and QtGui4.dll libraries
81 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
82 available as a separate package to make wpa_gui installation easier:
83 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
84 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
85 only shared key/password authentication is supported in this version
88 * added support for configuring password as NtPasswordHash
89 (16-byte MD4 hash of password) in hash:<32 hex digits> format
90 * added support for fallback from abbreviated TLS handshake to
91 full handshake when using EAP-FAST (e.g., due to an expired
93 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
94 draft (draft-ietf-emu-eap-gpsk-07.txt)
95 * added support for drivers that take care of RSN 4-way handshake
96 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
97 WPA_ALG_PMK in set_key)
98 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
99 .config); this version supports only ap_scan=2 mode and allow the
100 driver to take care of the 4-way handshake
101 * fixed a buffer overflow in parsing TSF from scan results when using
102 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
104 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
105 * fixed an integer overflow issue in the ASN.1 parser used by the
106 (experimental) internal TLS implementation to avoid a potential
108 * fixed a race condition with -W option (wait for a control interface
109 monitor before starting) that could have caused the first messages to
111 * added support for processing TNCC-TNCS-Messages to report
112 recommendation (allow/none/isolate) when using TNC [Bug 243]
115 * added network configuration parameter 'frequency' for setting
116 initial channel for IBSS (adhoc) networks
117 * added experimental IEEE 802.11r/D6.0 support
118 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
119 * updated EAP-PSK to use the IANA-allocated EAP type 47
120 * fixed EAP-PAX key derivation
121 * fixed EAP-PSK bit ordering of the Flags field
122 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
123 tunnelled identity request (previously, the identifier from the outer
124 method was used, not the tunnelled identifier which could be
126 * added support for fragmentation of outer TLS packets during Phase 2
127 of EAP-PEAP/TTLS/FAST
128 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
129 * added support for EAP-FAST authentication with inner methods that
130 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
131 for PAC provisioning)
132 * added support for authenticated EAP-FAST provisioning
133 * added support for configuring maximum number of EAP-FAST PACs to
134 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
135 * added support for storing EAP-FAST PACs in binary format
136 (fast_pac_format=binary in phase1 string)
137 * fixed dbus ctrl_iface to validate message interface before
138 dispatching to avoid a possible segfault [Bug 190]
139 * fixed PeerKey key derivation to use the correct PRF label
140 * updated Windows binary build to link against OpenSSL 0.9.8d and
141 added support for EAP-FAST
142 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
143 draft (draft-ietf-emu-eap-gpsk-04.txt)
144 * fixed EAP-AKA Notification processing to allow Notification to be
145 processed after AKA Challenge response has been sent
146 * updated to use IEEE 802.11w/D2.0 for management frame protection
148 * fixed EAP-TTLS implementation not to crash on use of freed memory
149 if TLS library initialization fails
150 * added support for EAP-TNC (Trusted Network Connect)
151 (this version implements the EAP-TNC method and EAP-TTLS changes
152 needed to run two methods in sequence (IF-T) and the IF-IMC and
153 IF-TNCCS interfaces from TNCC)
156 * added experimental, integrated TLSv1 client implementation with the
157 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
158 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
159 .config); this can be useful, e.g., if the target system does not
160 have a suitable TLS library and a minimal code size is required
161 (total size of this internal TLS/crypto code is bit under 50 kB on
162 x86 and the crypto code is shared by rest of the supplicant so some
163 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
164 * removed STAKey handshake since PeerKey handshake has replaced it in
165 IEEE 802.11ma and there are no known deployments of STAKey
166 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
167 draft (draft-ietf-emu-eap-gpsk-01.txt)
168 * added preliminary implementation of IEEE 802.11w/D1.0 (management
170 (Note: this requires driver support to work properly.)
171 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
172 * fixed Windows named pipes ctrl_iface to not stop listening for
173 commands if client program opens a named pipe and closes it
174 immediately without sending a command
175 * fixed USIM PIN status determination for the case that PIN is not
176 needed (this allows EAP-AKA to be used with USIM cards that do not
178 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
179 be used with cards that do not support file selection based on
181 * added support for matching the subjectAltName of the authentication
182 server certificate against multiple name components (e.g.,
183 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
184 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
185 affects IEEE 802.1X with dynamic WEP keys)
186 * changed ctrl_iface network configuration 'get' operations to not
187 return password/key material; if these fields are requested, "*"
188 will be returned if the password/key is set, but the value of the
189 parameter is not exposed
192 * added support for building Windows version with UNICODE defined
193 (wide-char functions)
194 * driver_ndis: fixed static WEP configuration to avoid race condition
195 issues with some NDIS drivers between association and setting WEP
197 * driver_ndis: added validation for IELength value in scan results to
198 avoid crashes when using buggy NDIS drivers [Bug 165]
199 * fixed Release|Win32 target in the Visual Studio project files
200 (previously, only Debug|Win32 target was set properly)
201 * changed control interface API call wpa_ctrl_pending() to allow it to
202 return -1 on error (e.g., connection lost); control interface clients
203 will need to make sure that they verify that the value is indeed >0
204 when determining whether there are pending messages
205 * added an alternative control interface backend for Windows targets:
206 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
207 control interface mechanism for Windows builds (previously, UDP to
209 * changed ctrl_interface configuration for UNIX domain sockets:
210 - deprecated ctrl_interface_group variable (it may be removed in
212 - allow both directory and group be configured with ctrl_interface
213 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
214 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
215 case when group is not changed
216 * added support for controlling more than one interface per process in
218 * added a workaround for a case where the AP is using unknown address
219 (e.g., MAC address of the wired interface) as the source address for
220 EAPOL-Key frames; previously, that source address was used as the
221 destination for EAPOL-Key frames and in key derivation; now, BSSID is
222 used even if the source address does not match with it
223 (this resolves an interoperability issue with Thomson SpeedTouch 580)
224 * added a workaround for UDP-based control interface (which was used in
225 Windows builds before this release) to prevent packets with forged
226 addresses from being accepted as local control requests
227 * removed ndis_events.cpp and possibility of using external
228 ndis_events.exe; C version (ndis_events.c) is fully functional and
229 there is no desire to maintain two separate versions of this
231 * ndis_events: Changed NDIS event notification design to use WMI to
232 learn the adapter description through Win32_PnPEntity class; this
233 should fix some cases where the adapter name was not recognized
234 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
236 * fixed selection of the first network in ap_scan=2 mode; previously,
237 wpa_supplicant could get stuck in SCANNING state when only the first
238 network for enabled (e.g., after 'wpa_cli select_network 0')
239 * winsvc: added support for configuring ctrl_interface parameters in
240 registry (ctrl_interface string value in
241 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
242 required to enable control interface (previously, this was hardcoded
244 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
245 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
248 * fixed build with CONFIG_STAKEY=y [Bug 143]
249 * added support for doing MLME (IEEE 802.11 management frame
250 processing) in wpa_supplicant when using Devicescape IEEE 802.11
251 stack (wireless-dev.git tree)
252 * added a new network block configuration option, fragment_size, to
253 configure the maximum EAP fragment size
254 * driver_ndis: Disable WZC automatically for the selected interface to
255 avoid conflicts with two programs trying to control the radio; WZC
256 will be re-enabled (if it was enabled originally) when wpa_supplicant
258 * added an experimental TLSv1 client implementation
259 (CONFIG_TLS=internal) that can be used instead of an external TLS
260 library, e.g., to reduce total size requirement on systems that do
261 not include any TLS library by default (this is not yet complete;
262 basic functionality is there, but certificate validation is not yet
264 * added PeerKey handshake implementation for IEEE 802.11e
265 direct link setup (DLS) to replace STAKey handshake
266 * fixed WPA PSK update through ctrl_iface for the case where the old
267 PSK was derived from an ASCII passphrase and the new PSK is set as
268 a raw PSK (hex string)
269 * added new configuration option for identifying which network block
270 was used (id_str in wpa_supplicant.conf; included on
271 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
272 variable in wpa_cli action scripts; in addition WPA_ID variable is
273 set to the current unique identifier that wpa_supplicant assigned
274 automatically for the network and that can be used with
275 GET_NETWORK/SET_NETWORK ctrl_iface commands)
276 * wpa_cli action script is now called only when the connect/disconnect
277 status changes or when associating with a different network
278 * fixed configuration parser not to remove CCMP from group cipher list
279 if WPA-None (adhoc) is used (pairwise=NONE in that case)
280 * fixed integrated NDIS events processing not to hang the process due
281 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
282 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
283 draft-clancy-emu-eap-shared-secret-00.txt)
284 * added Microsoft Visual Studio 2005 solution and project files for
285 build wpa_supplicant for Windows (see vs2005 subdirectory)
286 * eloop_win: fixed unregistration of Windows events
287 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
288 at the end of RSN pre-authentication and added unregistration of
289 a Windows event to avoid getting eloop_win stuck with an invalid
291 * driver_ndis: added support for selecting AP based on BSSID
292 * added new environmental variable for wpa_cli action scripts:
293 WPA_CTRL_DIR is the current control interface directory
294 * driver_ndis: added support for using NDISUIO instead of WinPcap for
295 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
296 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
297 wpa_supplicant without requiring WinPcap; note that using NDISUIO
298 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
299 only one application to open the device
300 * changed NDIS driver naming to only include device GUID, e.g.,
301 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
302 specific \Device\NPF_ prefix before the GUID; the prefix is still
303 allowed for backwards compatibility, but it is not required anymore
304 when specifying the interface
305 * driver_ndis: re-initialize driver interface is the adapter is removed
306 and re-inserted [Bug 159]
307 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
308 big endian hosts [Bug 146]
311 * fixed EAP-GTC response to include correct user identity when run as
312 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
313 * driver_ndis: Fixed encryption mode configuration for unencrypted
314 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
315 refused to associate with open networks) [Bug 106]
316 * driver_ndis: use BSSID OID polling to detect when IBSS network is
317 formed even when ndis_events code is included since some NDIS drivers
318 do not generate media connect events in IBSS mode
319 * config_winreg: allow global ctrl_interface parameter to be configured
321 * config_winreg: added support for saving configuration data into
323 * added support for controlling network device operational state
324 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
325 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
326 that can use this information)
327 * driver_wext: added support for WE-21 change to SSID configuration
328 * driver_wext: fixed privacy configuration for static WEP keys mode
330 * added an optional driver_ops callback for MLME-SETPROTECTION.request
332 * added support for EAP-SAKE (no EAP method number allocated yet, so
333 this is using the same experimental type 255 as EAP-PSK)
334 * added support for dynamically loading EAP methods (.so files) instead
335 of requiring them to be statically linked in; this is disabled by
336 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
340 * do not try to use USIM APDUs when initializing PC/SC for SIM card
341 access for a network that has not enabled EAP-AKA
342 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
343 v0.5.1 due to the new support for expanded EAP types)
344 * added support for generating EAP Expanded Nak
345 * try to fetch scan results once before requesting new scan when
346 starting up in ap_scan=1 mode (this can speed up initial association
347 a lot with, e.g., madwifi-ng driver)
348 * added support for receiving EAPOL frames from a Linux bridge
349 interface (-bbr0 on command line)
350 * fixed EAPOL re-authentication for sessions that used PMKSA caching
351 * changed EAP method registration to use a dynamic list of methods
352 instead of a static list generated at build time
353 * fixed PMKSA cache deinitialization not to use freed memory when
354 removing PMKSA entries
355 * fixed a memory leak in EAP-TTLS re-authentication
356 * reject WPA/WPA2 message 3/4 if it does not include any valid
358 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
359 if the driver does not support SIOCSIWAUTH
362 * driver_test: added better support for multiple APs and STAs by using
363 a directory with sockets that include MAC address for each device in
364 the name (driver_param=test_dir=/tmp/test)
365 * added support for EAP expanded type (vendor specific EAP methods)
366 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
367 option can be changed if needed
368 * wpa_cli/wpa_gui: skip non-socket files in control directory when
369 using UNIX domain sockets; this avoids selecting an incorrect
370 interface (e.g., a PID file could be in this directory, even though
371 use of this directory for something else than socket files is not
373 * fixed TLS library deinitialization after RSN pre-authentication not
374 to disable TLS library for normal authentication
375 * driver_wext: Remove null-termination from SSID length if the driver
376 used it; some Linux drivers do this and they were causing problems in
377 wpa_supplicant not finding matching configuration block. This change
378 would break a case where the SSID actually ends in '\0', but that is
379 not likely to happen in real use.
380 * fixed PMKSA cache processing not to trigger deauthentication if the
381 current PMKSA cache entry is replaced with a valid new entry
382 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
383 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
386 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
387 * added experimental STAKey handshake implementation for IEEE 802.11e
388 direct link setup (DLS); note: this is disabled by default in both
389 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
391 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
392 decrypt AT_ENCR_DATA attributes correctly
393 * fixed EAP-AKA to allow resynchronization within the same session
394 * made code closer to ANSI C89 standard to make it easier to port to
395 other C libraries and compilers
396 * started moving operating system or C library specific functions into
397 wrapper functions defined in os.h and implemented in os_*.c to make
399 * wpa_supplicant can now be built with Microsoft Visual C++
400 (e.g., with the freely available Toolkit 2003 version or Visual
401 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
402 example makefile for nmake
403 * added support for using Windows registry for command line parameters
404 (CONFIG_MAIN=main_winsvc) and configuration data
405 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
406 contents; this version can be run both as a Windows service and as a
407 normal application; 'wpasvc.exe app' to start as applicant,
408 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
409 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
411 * made it possible to link ndis_events.exe functionality into
412 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
413 * added better support for multiple control interface backends
414 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
415 * fixed PC/SC code to use correct length for GSM AUTH command buffer
416 and to not use pioRecvPci with SCardTransmit() calls; these were not
417 causing visible problems with pcsc-lite, but Windows Winscard.dll
418 refused the previously used parameters; this fixes EAP-SIM and
419 EAP-AKA authentication using SIM/USIM card under Windows
420 * added new event loop implementation for Windows using
421 WaitForMultipleObject() instead of select() in order to allow waiting
422 for non-socket objects; this can be selected with
423 CONFIG_ELOOP=eloop_win in .config
424 * added support for selecting l2_packet implementation in .config
425 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
426 winpcap, freebsd, none)
427 * added new l2_packet implementation for WinPcap
428 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
429 reduce latency in EAPOL receive processing from about 100 ms to about
431 * added support for EAP-FAST key derivation using other ciphers than
432 RC4-128-SHA for authentication and AES128-SHA for provisioning
433 * added support for configuring CA certificate as DER file and as a
435 * fixed private key configuration as configuration blob and added
436 support for using PKCS#12 as a blob
437 * tls_gnutls: added support for using PKCS#12 files; added support for
439 * added support for loading trusted CA certificates from Windows
440 certificate store: ca_cert="cert_store://<name>", where <name> is
441 likely CA (Intermediate CA certificates) or ROOT (root certificates)
442 * added C version of ndis_events.cpp and made it possible to build this
443 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
444 easily on cross-compilation builds
445 * added wpasvc.exe into Windows binary release; this is an alternative
446 version of wpa_supplicant.exe with configuration backend using
447 Windows registry and with the entry point designed to run as a
449 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
450 wpasvc.exe and removed this additional tool from the Windows binary
451 release since it is not needed anymore
452 * load winscard.dll functions dynamically when building with MinGW
453 since MinGW does not yet include winscard library
455 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
456 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
457 and WinPcap to receive frames sent to PAE group address
458 * disable EAP state machine when IEEE 802.1X authentication is not used
459 in order to get rid of bogus "EAP failed" messages
460 * fixed OpenSSL error reporting to go through all pending errors to
461 avoid confusing reports of old errors being reported at later point
463 * fixed configuration file updating to not write empty variables
464 (e.g., proto or key_mgmt) that the file parser would not accept
465 * fixed ADD_NETWORK ctrl_iface command to use the same default values
466 for variables as empty network definitions read from config file
468 * fixed EAP state machine to not discard EAP-Failure messages in many
469 cases (e.g., during TLS handshake)
470 * fixed a infinite loop in private key reading if the configured file
471 cannot be parsed successfully
472 * driver_madwifi: added support for madwifi-ng
473 * wpa_gui: do not display password/PSK field contents
474 * wpa_gui: added CA certificate configuration
475 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
476 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
477 the new AP is using different WPA/RSN IE
478 * use longer timeout for IEEE 802.11 association to avoid problems with
479 drivers that may take more than five second to associate
482 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
483 RSN IE, but WPA IE would match with wpa_supplicant configuration
484 * added support for named configuration blobs in order to avoid having
485 to use file system for external files (e.g., certificates);
486 variables can be set to "blob://<blob name>" instead of file path to
487 use a named blob; supported fields: pac_file, client_cert,
489 * fixed RSN pre-authentication (it was broken in the clean up of WPA
490 state machine interface in v0.4.5)
491 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
492 sure the driver configures broadcast decryption correctly
493 * added ca_path (and ca_path2) configuration variables that can be used
494 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
495 system-wide trusted CA list
496 * added support for starting wpa_supplicant without a configuration
497 file (-C argument must be used to set ctrl_interface parameter for
498 this case; in addition, -p argument can be used to provide
499 driver_param; these new arguments can also be used with a
500 configuration to override the values from the configuration)
501 * added global control interface that can be optionally used for adding
502 and removing network interfaces dynamically (-g command line argument
503 for both wpa_supplicant and wpa_cli) without having to restart
504 wpa_supplicant process
506 - try to save configuration whenever something is modified
507 - added WEP key configuration
508 - added possibility to edit the current network configuration
509 * driver_ndis: fixed driver polling not to increase frequency on each
510 received EAPOL frame due to incorrectly cancelled timeout
511 * added simple configuration file examples (in examples subdirectory)
512 * fixed driver_wext.c to filter wireless events based on ifindex to
513 avoid interfaces receiving events from other interfaces
514 * delay sending initial EAPOL-Start couple of seconds to speed up
515 authentication for the most common case of Authenticator starting
516 EAP authentication immediately after association
519 * added a workaround for clearing keys with ndiswrapper to allow
520 roaming from WPA enabled AP to plaintext one
521 * added docbook documentation (doc/docbook) that can be used to
522 generate, e.g., man pages
523 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
524 PF_PACKET in order to prepare for network devices that do not use
525 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
526 * use receipt of EAPOL-Key frame as a lower layer success indication
527 for EAP state machine to allow recovery from dropped EAP-Success
529 * cleaned up internal EAPOL frame processing by not including link
530 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
531 header is added only when transmitted the frame; this makes it easier
532 to use wpa_supplicant on link layers that use different header than
534 * updated EAP-PSK to use draft 9 by default since this can now be
535 tested with hostapd; removed support for draft 3, including
536 server_nai configuration option from network blocks
537 * driver_wired: add PAE address to the multicast address list in order
538 to be able to receive EAPOL frames with drivers that do not include
539 these multicast addresses by default
540 * driver_wext: add support for WE-19
541 * added support for multiple configuration backends (CONFIG_BACKEND
542 option); currently, only 'file' is supported (i.e., the format used
543 in wpa_supplicant.conf)
544 * added support for updating configuration ('wpa_cli save_config');
545 this is disabled by default and can be enabled with global
546 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
547 and wpa_gui to store the configuration changes in a permanent store
548 * added GET_NETWORK ctrl_iface command
549 (e.g., 'wpa_cli get_network 0 ssid')
552 * replaced OpenSSL patch for EAP-FAST support
553 (openssl-tls-extensions.patch) with a more generic and correct
554 patch (the new patch is not compatible with the previous one, so the
555 OpenSSL library will need to be patched with the new patch in order
556 to be able to build wpa_supplicant with EAP-FAST support)
557 * added support for using Windows certificate store (through CryptoAPI)
558 for client certificate and private key operations (EAP-TLS)
559 (see wpa_supplicant.conf for more information on how to configure
560 this with private_key)
561 * ported wpa_gui to Windows
562 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
563 built with the open source version of the Qt4 for Windows
564 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
565 with drivers that do not support WPA
566 * ndis_events: fixed Windows 2000 support
567 * added support for enabling/disabling networks from the list of all
568 configured networks ('wpa_cli enable_network <network id>' and
569 'wpa_cli disable_network <network id>')
570 * added support for adding and removing network from the current
571 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
572 <network id>'); added networks are disabled by default and they can
573 be enabled with enable_network command once the configuration is done
574 for the new network; note: configuration file is not yet updated, so
575 these new networks are lost when wpa_supplicant is restarted
576 * added support for setting network configuration parameters through
577 the control interface, for example:
578 wpa_cli set_network 0 ssid "\"my network\""
579 * fixed parsing of strings that include both " and # within double
580 quoted area (e.g., "start"#end")
581 * added EAP workaround for PEAP session resumption: allow outer,
582 i.e., not tunneled, EAP-Success to terminate session since; this can
583 be disabled with eap_workaround=0
584 (this was allowed for PEAPv1 before, but now it is also allowed for
585 PEAPv0 since at least one RADIUS authentication server seems to be
586 doing this for PEAPv0, too)
587 * wpa_gui: added preliminary support for adding new networks to the
588 wpa_supplicant configuration (double click on the scan results to
589 open network configuration)
592 * removed interface for external EAPOL/EAP supplicant (e.g.,
593 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
594 anymore and is unlikely to be used by anyone
595 * driver_ndis: fixed WinPcap 3.0 support
596 * fixed build with CONFIG_DNET_PCAP=y on Linux
597 * l2_packet: moved different implementations into separate files
601 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
602 (note: ipw2100-1.1.0 is likely to require an update to work with
604 * added support for using ap_scan=2 mode with multiple network blocks;
605 wpa_supplicant will go through the networks one by one until the
606 driver reports a successful association; this uses the same order for
607 networks as scan_ssid=1 scans, i.e., the priority field is ignored
608 and the network block order in the file is used instead
609 * fixed a potential issue in RSN pre-authentication ending up using
610 freed memory if pre-authentication times out
611 * added support for matching alternative subject name extensions of the
612 authentication server certificate; new configuration variables
613 altsubject_match and altsubject_match2
614 * driver_ndis: added support for IEEE 802.1X authentication with wired
616 * added support for querying private key password (EAP-TLS) through the
617 control interface (wpa_cli/wpa_gui) if one is not included in the
619 * driver_broadcom: fixed couple of memory leaks in scan result
621 * EAP-PAX is now registered as EAP type 46
622 * fixed EAP-PAX MAC calculation
623 * fixed EAP-PAX CK and ICK key derivation
624 * added support for using password with EAP-PAX (as an alternative to
625 entering key with eappsk); SHA-1 hash of the password will be used as
627 * added support for arbitrary driver interface parameters through the
628 configuration file with a new driver_param field; this adds a new
629 driver_ops function set_param()
630 * added possibility to override l2_packet module with driver interface
631 API (new send_eapol handler); this can be used to implement driver
632 specific TX/RX functions for EAPOL frames
633 * fixed ctrl_interface_group processing for the case where gid is
634 entered as a number, not group name
635 * driver_test: added support for testing hostapd with wpa_supplicant
636 by using test driver interface without any kernel drivers or network
640 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
641 packets to be encrypted; this was apparently broken by the changed
642 ioctl order in v0.4.0
643 * driver_madwifi: added preliminary support for compiling against 'BSD'
644 branch of madwifi CVS tree
645 * added support for EAP-MSCHAPv2 password retries within the same EAP
646 authentication session
647 * added support for password changes with EAP-MSCHAPv2 (used when the
648 password has expired)
649 * added support for reading additional certificates from PKCS#12 files
650 and adding them to the certificate chain
651 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
653 * fixed a possible double free in EAP-TTLS fast-reauthentication when
654 identity or password is entered through control interface
655 * display EAP Notification messages to user through control interface
656 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
657 * added GUI version of wpa_cli, wpa_gui; this is not build
658 automatically with 'make'; use 'make wpa_gui' to build (this requires
659 Qt development tools)
660 * added 'disconnect' command to control interface for setting
661 wpa_supplicant in state where it will not associate before
662 'reassociate' command has been used
663 * added support for selecting a network from the list of all configured
664 networks ('wpa_cli select_network <network id>'; this disabled all
665 other networks; to re-enable, 'wpa_cli select_network any')
666 * added support for getting scan results through control interface
667 * added EAP workaround for PEAPv1 session resumption: allow outer,
668 i.e., not tunneled, EAP-Success to terminate session since; this can
669 be disabled with eap_workaround=0
671 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
672 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
673 used to reduce the size of the wpa_supplicant considerably if
674 debugging code is not needed
675 * fixed EAPOL-Key validation to drop packets with invalid Key Data
676 Length; such frames could have crashed wpa_supplicant due to buffer
678 * added support for wired authentication (IEEE 802.1X on wired
679 Ethernet); driver interface 'wired'
680 * obsoleted set_wpa() handler in the driver interface API (it can be
681 replaced by moving enable/disable functionality into init()/deinit())
682 (calls to set_wpa() are still present for backwards compatibility,
683 but they may be removed in the future)
684 * driver_madwifi: fixed association in plaintext mode
685 * modified the EAP workaround that accepts EAP-Success with incorrect
686 Identifier to be even less strict about verification in order to
687 interoperate with some authentication servers
688 * added support for sending TLS alerts
689 * added support for 'any' SSID wildcard; if ssid is not configured or
690 is set to an empty string, any SSID will be accepted for non-WPA AP
691 * added support for asking PIN (for SIM) from frontends (e.g.,
692 wpa_cli); if a PIN is needed, but not included in the configuration
693 file, a control interface request is sent and EAP processing is
694 delayed until the PIN is available
695 * added support for using external devices (e.g., a smartcard) for
696 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
697 new wpa_supplicant.conf variables:
698 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
699 - network: engine, engine_id, key_id
700 * added experimental support for EAP-PAX
701 * added monitor mode for wpa_cli (-a<path to a program to run>) that
702 allows external commands (e.g., shell scripts) to be run based on
703 wpa_supplicant events, e.g., when authentication has been completed
704 and data connection is ready; other related wpa_cli arguments:
705 -B (run in background), -P (write PID file); wpa_supplicant has a new
706 command line argument (-W) that can be used to make it wait until a
707 control interface command is received in order to avoid missing
709 * added support for opportunistic WPA2 PMKSA key caching (disabled by
710 default, can be enabled with proactive_key_caching=1)
711 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
712 Authenticator rejects PMKSA caching attempt and the driver is not
713 using assoc_info events
714 * added -P<pid file> argument for wpa_supplicant to write the current
715 process id into a file
717 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
718 * added new phase1 option parameter, include_tls_length=1, to force
719 wpa_supplicant to add TLS Message Length field to all TLS messages
720 even if the packet is not fragmented; this may be needed with some
721 authentication servers
722 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
723 using drivers that take care of AP selection (e.g., when using
725 * fixed reprocessing of pending request after ctrl_iface requests for
726 identity/password/otp
727 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
728 EAP-PEAP and EAP-TTLS
729 * all drivers using driver_wext: set interface up and select Managed
730 mode when starting wpa_supplicant; set interface down when exiting
731 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
732 ipw2100 and ipw2200; please note that this also changed the
733 configuration variable in .config to CONFIG_DRIVER_IPW
736 * fixed a busy loop introduced in v0.3.5 for scan result processing
737 when no matching AP is found
740 * added a workaround for an interoperability issue with a Cisco AP
742 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
743 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
744 retransmission of dropped frames)
745 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
746 (e.g., segfault when processing EAPOL-Key frames)
747 * fixed EAP workaround and fast reauthentication configuration for
748 RSN pre-authentication; previously these were disabled and
749 pre-authentication would fail if the used authentication server
750 requires EAP workarounds
751 * added support for blacklisting APs that fail or timeout
752 authentication in ap_scan=1 mode so that all APs are tried in cases
753 where the ones with strongest signal level are failing authentication
754 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
755 authentication attempt
756 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
757 in the previous authentication (previously, only Phase 1 success was
761 * added preliminary support for IBSS (ad-hoc) mode configuration
762 (mode=1 in network block); this included a new key_mgmt mode
763 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
764 key management; see wpa_supplicant.conf for more details and an
765 example on how to configure this (note: this is currently implemented
766 only for driver_hostapd.c, but the changes should be trivial to add
767 in associate() handler for other drivers, too (assuming the driver
769 * added preliminary port for native Windows (i.e., no cygwin) using
773 * added optional support for GNU Readline and History Libraries for
774 wpa_cli (CONFIG_READLINE)
775 * cleaned up EAP state machine <-> method interface and number of
776 small problems with error case processing not terminating on
777 EAP-Failure but waiting for timeout
778 * added couple of workarounds for interoperability issues with a
779 Cisco AP when using WPA2
780 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
781 Note: This requires a patch for openssl to add support for TLS
782 extensions and number of workarounds for operations without
783 certificates. Proof of concept type of experimental patch is
784 included in openssl-tls-extensions.patch.
787 * fixed private key loading for cases where passphrase is not set
788 * fixed Windows/cygwin L2 packet handler freeing; previous version
789 could cause a segfault when RSN pre-authentication was completed
790 * added support for PMKSA caching with drivers that generate RSN IEs
791 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
792 but similar code can be easily added to driver_ndiswrapper.c once
793 ndiswrapper gets full support for RSN PMKSA caching
794 * improved recovery from PMKID mismatches by requesting full EAP
795 authentication in case of failed PMKSA caching attempt
796 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
797 (this requires that ndis_events is ran while wpa_supplicant is
799 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
800 * added support for driver interfaces to replace the interface name
801 based on driver/OS specific mapping, e.g., in case of driver_ndis,
802 this allows the beginning of the adapter description to be used as
804 * added support for CR+LF (Windows-style) line ends in configuration
806 * driver_ndis: enable radio before starting scanning, disable radio
808 * modified association event handler to set portEnabled = FALSE before
809 clearing port Valid in order to reset EAP state machine and avoid
810 problems with new authentication getting ignored because of state
811 machines ending up in AUTHENTICATED/SUCCESS state based on old
813 * added support for driver events to add PMKID candidates in order to
814 allow drivers to give priority to most likely roaming candidates
815 * driver_hostap: moved PrivacyInvoked configuration to associate()
816 function so that this will not be set for plaintext connections
817 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
818 interface can distinguish plaintext and IEEE 802.1X (no WPA)
820 * fixed static WEP key configuration to use broadcast/default type for
821 all keys (previously, the default TX key was configured as pairwise/
823 * driver_ndis: added legacy WPA capability detection for non-WPA2
825 * added support for setting static WEP keys for IEEE 802.1X without
826 dynamic WEP keying (eapol_flags=0)
829 * added support for reading PKCS#12 (PFX) files (as a replacement for
830 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
831 * fixed compilation with CONFIG_PCSC=y
832 * added new ap_scan mode, ap_scan=2, for drivers that take care of
833 association, but need to be configured with security policy and SSID,
834 e.g., ndiswrapper and NDIS driver; this mode should allow such
835 drivers to work with hidden SSIDs and optimized roaming; when
836 ap_scan=2 is used, only the first network block in the configuration
837 file is used and this configuration should have explicit security
838 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
839 group, proto variables
840 * added experimental port of wpa_supplicant for Windows
841 - driver_ndis.c driver interface (NDIS OIDs)
842 - currently, this requires cygwin and WinPcap
843 - small utility, win_if_list, can be used to get interface name
844 * control interface can now be removed at build time; add
845 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
846 * optional Xsupplicant interface can now be removed at build time;
847 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
848 * added auth_alg to driver interface associate() parameters to make it
849 easier for drivers to configure authentication algorithm as part of
852 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
853 * driver_broadcom: added new driver interface for Broadcom wl.o driver
854 (a generic driver for Broadcom IEEE 802.11a/g cards)
855 * wpa_cli: fixed parsing of -p <path> command line argument
856 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
857 ACK, not tunneled EAP-Success (of which only the first byte was
858 actually send due to a bug in previous code); this seems to
859 interoperate with most RADIUS servers that implements PEAPv1
860 * PEAPv1: added support for terminating PEAP authentication on tunneled
861 EAP-Success message; this can be configured by adding
862 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
863 (some RADIUS servers require this whereas others require a tunneled
865 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
866 the old label for key derivation; previously, the default was 1,
867 but it looks like most existing PEAPv1 implementations use the old
868 label which is thus more suitable default option
869 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
870 * fixed parsing of wep_tx_keyidx
871 * added support for configuring list of allowed Phase 2 EAP types
872 (for both EAP-PEAP and EAP-TTLS) instead of only one type
873 * added support for configuring IEEE 802.11 authentication algorithm
874 (auth_alg; mainly for using Shared Key authentication with static
876 * added support for EAP-AKA (with UMTS SIM)
877 * fixed couple of errors in PCSC handling that could have caused
878 random-looking errors for EAP-SIM
879 * added support for EAP-SIM pseudonyms and fast re-authentication
880 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
882 * added support for EAP-SIM with two challanges
883 (phase1="sim_min_num_chal=3" can be used to require three challenges)
884 * added support for configuring DH/DSA parameters for an ephemeral DH
885 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
886 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
887 and optional DH key exchange to achieve forward secracy with RSA keys
888 * added support for matching subject of the authentication server
889 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
890 configuration variables subject_match and subject_match2
891 * changed SSID configuration in driver_wext.c (used by many driver
892 interfaces) to use ssid_len+1 as the length for SSID since some Linux
894 * fixed couple of unaligned reads in scan result parsing to fix WPA
895 connection on some platforms (e.g., ARM)
896 * added driver interface for Intel ipw2100 driver
897 * added support for LEAP with WPA
898 * added support for larger scan results report (old limit was 4 kB of
899 data, i.e., about 35 or so APs) when using Linux wireless extensions
901 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
902 only if there is a PMKSA cache entry for the current AP
903 * fixed error handling for case where reading of scan results fails:
904 must schedule a new scan or wpa_supplicant will remain waiting
906 * changed debug output to remove shared password/key material by
907 default; all key information can be included with -K command line
908 argument to match the previous behavior
909 * added support for timestamping debug log messages (disabled by
910 default, can be enabled with -t command line argument)
911 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
912 if keys are not configured to be used; this fixes IEEE 802.1X mode
913 with drivers that use this information to configure whether Privacy
914 bit can be in Beacon frames (e.g., ndiswrapper)
915 * avoid clearing driver keys if no keys have been configured since last
916 key clear request; this seems to improve reliability of group key
917 handshake for ndiswrapper & NDIS driver which seems to be suffering
918 of some kind of timing issue when the keys are cleared again after
920 * changed driver interface API:
921 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
922 version is being used (now, this is set to 2; previously, it was
924 - pass pointer to private data structure to all calls
925 - the new API is not backwards compatible; all in-tree driver
926 interfaces has been converted to the new API
927 * added support for controlling multiple interfaces (radios) per
928 wpa_supplicant process; each interface needs to be listed on the
929 command line (-c, -i, -D arguments) with -N as a separator
930 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
931 * added a workaround for EAP servers that incorrectly use same Id for
932 sequential EAP packets
933 * changed libpcap/libdnet configuration to use .config variable,
934 CONFIG_DNET_PCAP, instead of requiring Makefile modification
935 * improved downgrade attack detection in IE verification of msg 3/4:
936 verify both WPA and RSN IEs, if present, not only the selected one;
937 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
938 Probe Response frame, and RSN is enabled in wpa_supplicant
940 * fixed WPA msg 3/4 processing to allow Key Data field contain other
941 IEs than just one WPA IE
942 * added support for FreeBSD and driver interface for the BSD net80211
943 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
944 required kernel mods have not yet been committed
945 * made EAP workarounds configurable; enabled by default, can be
946 disabled with network block option eap_workaround=0
948 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
949 * resolved couple of interoperability issues with EAP-PEAPv1 and
950 Phase 2 (inner EAP) fragment reassembly
951 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
952 AP is using non-zero key index for the unicast key and key index zero
953 for the broadcast key
954 * driver_hostap: fixed IEEE 802.1X WEP key updates and
955 re-authentication by allowing unencrypted EAPOL frames when not using
957 * added a new driver interface, 'wext', which uses only standard,
958 driver independent functionality in Linux wireless extensions;
959 currently, this can be used only for non-WPA IEEE 802.1X mode, but
960 eventually, this is to be extended to support full WPA/WPA2 once
961 Linux wireless extensions get support for this
962 * added support for mode in which the driver is responsible for AP
963 scanning and selection; this is disabled by default and can be
964 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
965 this mode can be used, e.g., with generic 'wext' driver interface to
966 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
967 supporting wireless extensions.
968 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
969 operation with an AP that does not include SSID in the Beacon frames)
970 * added support for new EAP authentication methods:
971 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
972 * added support for asking one-time-passwords from frontends (e.g.,
973 wpa_cli); this 'otp' command works otherwise like 'password' command,
974 but the password is used only once and the frontend will be asked for
975 a new password whenever a request from authenticator requires a
976 password; this can be used with both EAP-OTP and EAP-GTC
977 * changed wpa_cli to automatically re-establish connection so that it
978 does not need to be re-started when wpa_supplicant is terminated and
980 * improved user data (identity/password/otp) requests through
981 frontends: process pending EAPOL packets after getting new
982 information so that full authentication does not need to be
983 restarted; in addition, send pending requests again whenever a new
985 * changed control frontends to use a new directory for socket files to
986 make it easier for wpa_cli to automatically select between interfaces
987 and to provide access control for the control interface;
988 wpa_supplicant.conf: ctrl_interface is now a path
989 (/var/run/wpa_supplicant is the recommended path) and
990 ctrl_interface_group can be used to select which group gets access to
991 the control interface;
992 wpa_cli: by default, try to connect to the first interface available
993 in /var/run/wpa_supplicant; this path can be overriden with -p option
994 and an interface can be selected with -i option (i.e., in most common
995 cases, wpa_cli does not need to get any arguments)
996 * added support for LEAP
997 * added driver interface for Linux ndiswrapper
998 * added priority option for network blocks in the configuration file;
999 this allows networks to be grouped based on priority (the scan
1000 results are searched for matches with network blocks in this order)
1003 * sort scan results to improve AP selection
1004 * fixed control interface socket removal for some error cases
1005 * improved scan requesting and authentication timeout
1006 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1008 * PEAP version can now be forced with phase1="peapver=<ver>"
1009 (mostly for testing; by default, the highest version supported by
1010 both the Supplicant and Authentication Server is selected
1012 * added support for madwifi driver (Atheros ar521x)
1013 * added a workaround for cases where AP sets Install Tx/Rx bit for
1014 WPA Group Key messages when pairwise keys are used (without this,
1015 the Group Key would be used for Tx and the AP would drop frames
1017 * added GSM SIM/USIM interface for GSM authentication algorithm for
1018 EAP-SIM; this requires pcsc-lite
1019 * added support for ATMEL AT76C5XXx driver
1020 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1021 does not include key data in the EAPOL-Key frame (i.e., part of
1022 EAP keying material is used as data encryption key)
1023 * added support for using plaintext and static WEP networks
1027 * added support for new EAP authentication methods:
1028 EAP-TTLS/EAP-MD5-Challenge
1030 EAP-TTLS/EAP-MSCHAPv2
1038 EAP-PEAP/MD5-Challenge
1040 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1041 * added support for anonymous identity (to be used when identity is
1042 sent in plaintext; real identity will be used within TLS protected
1043 tunnel (e.g., with EAP-TTLS)
1044 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1045 * added support for requesting identity and password information using
1046 control interface; in other words, the password for EAP-PEAP or
1047 EAP-TTLS does not need to be included in the configuration file since
1048 a frontand (e.g., wpa_cli) can ask it from the user
1049 * improved RSN pre-authentication to use a candidate list and process
1050 all candidates from each scan; not only one per scan
1051 * fixed RSN IE and WPA IE capabilities field parsing
1052 * ignore Tx bit in GTK IE when Pairwise keys are used
1053 * avoid making new scan requests during IEEE 802.1X negotiation
1054 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1055 with TLS support (this replaces the included implementation with
1056 library code to save about 8 kB since the library code is needed
1058 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1059 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1062 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1064 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1065 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1066 - EAP-MD5 (cannot be used with WPA-RADIUS)
1067 [draft-ietf-eap-rfc2284bis-09.txt]
1068 - EAP-TLS [RFC 2716]
1069 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1070 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1071 [draft-kamath-pppext-eap-mschapv2-00.txt]
1072 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1073 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1074 - new configuration file options: eap, identity, password, ca_cert,
1075 client_cert, privatekey, private_key_passwd
1076 - Xsupplicant is not required anymore, but it can be used by
1077 disabling the internal IEEE 802.1X Supplicant with -e command line
1079 - this code is not included in the default build; Makefile need to
1080 be edited for this (uncomment lines for selected functionality)
1081 - EAP-TLS and EAP-PEAP require openssl libraries
1082 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1083 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1084 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1085 EAPOL-Key frames instead of WPA key handshakes)
1086 * added support for IEEE 802.11i/RSN (WPA2)
1087 - improved PTK Key Handshake
1088 - PMKSA caching, pre-authentication
1089 * fixed wpa_supplicant to ignore possible extra data after WPA
1090 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1091 TPTK' error from message 3 of 4-Way Handshake in case the AP
1092 includes extra data after the EAPOL-Key)
1093 * added interface for external programs (frontends) to control
1095 - CLI example (wpa_cli) with interactive mode and command line
1097 - replaced SIGUSR1 status/statistics with the new control interface
1098 * made some feature compile time configurable
1099 - .config file for make
1100 - driver interfaces (hostap, hermes, ..)
1101 - EAPOL/EAP functions
1104 * Initial version of wpa_supplicant
