1 ChangeLog for wpa_supplicant
4 * added support for SHA-256 as X.509 certificate digest when using the
5 internal X.509/TLSv1 implementation
6 * updated management frame protection to use IEEE 802.11w/D6.0
7 * added support for using SHA256-based stronger key derivation for WPA2
11 * added support for EAP Sequences in EAP-FAST Phase 2
12 * added support for using TNC with EAP-FAST
13 * added driver_ps3 for the PS3 Linux wireless driver
14 * added support for optional cryptobinding with PEAPv0
15 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
16 allow fallback to full handshake if server rejects PAC-Opaque
17 * added fragmentation support for EAP-TNC
18 * added support for parsing PKCS #8 formatted private keys into the
19 internal TLS implementation (both PKCS #1 RSA key and PKCS #8
20 encapsulated RSA key can now be used)
21 * added option of using faster, but larger, routines in the internal
22 LibTomMath (for internal TLS implementation) to speed up DH and RSA
23 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
24 * fixed race condition between disassociation event and group key
25 handshake to avoid getting stuck in incorrect state [Bug 261]
26 * fixed opportunistic key caching (proactive_key_caching)
29 * removed 'nai' and 'eappsk' network configuration variables that were
30 previously used for configuring user identity and key for EAP-PSK,
31 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
32 replacement for 'nai' (if old configuration used a separate
33 'identity' value, that would now be configured as
34 'anonymous_identity'). 'password' field is now used as the
35 replacement for 'eappsk' (it can also be set using hexstring to
36 present random binary data)
37 * removed '-w' command line parameter (wait for interface to be added,
38 if needed); cleaner way of handling this functionality is to use an
39 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
40 when an interface is added
41 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
42 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
43 indicating when new scan results become available
44 * added new ctrl_iface command, BSS, to allow scan results to be
45 fetched without hitting the message size limits (this command
46 can be used to iterate through the scan results one BSS at the time)
47 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
48 attributes in EAP-SIM Start/Response when using fast reauthentication
49 * fixed EAPOL not to end up in infinite loop when processing dynamic
50 WEP keys with IEEE 802.1X
51 * fixed problems in getting NDIS events from WMI on Windows 2000
54 * added support for Makefile builds to include debug-log-to-a-file
55 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
56 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
57 lengths properly to avoid potential crash caused by invalid messages
58 * added data structure for storing allocated buffers (struct wpabuf);
59 this does not affect wpa_supplicant usage, but many of the APIs
60 changed and various interfaces (e.g., EAP) is not compatible with old
62 * added support for protecting EAP-AKA/Identity messages with
63 AT_CHECKCODE (optional feature in RFC 4187)
64 * added support for protected result indication with AT_RESULT_IND for
65 EAP-SIM and EAP-AKA (phase1="result_ind=1")
66 * added driver_wext workaround for race condition between scanning and
67 association with drivers that take very long time to scan all
68 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
69 using a longer hardcoded timeout for the scan if the driver supports
70 notifications for scan completion (SIOCGIWSCAN event); this helps,
71 e.g., in cases where wpa_supplicant and madwifi driver ended up in
72 loop where the driver did not even try to associate
73 * stop EAPOL timer tick when no timers are in use in order to reduce
74 power consumption (no need to wake up the process once per second)
76 * added support for privilege separation (run only minimal part of
77 wpa_supplicant functionality as root and rest as unprivileged,
78 non-root process); see 'Privilege separation' in README for details;
79 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
81 * changed scan results data structure to include all information
82 elements to make it easier to support new IEs; old get_scan_result()
83 driver_ops is still supported for backwards compatibility (results
84 are converted internally to the new format), but all drivers should
85 start using the new get_scan_results2() to make them more likely to
86 work with new features
87 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
88 application, i.e., it does not require Qt3Support anymore; Windows
89 binary of wpa_gui.exe is now from this directory and only requires
90 QtCore4.dll and QtGui4.dll libraries
91 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
92 available as a separate package to make wpa_gui installation easier:
93 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
94 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
95 only shared key/password authentication is supported in this version
98 * added support for configuring password as NtPasswordHash
99 (16-byte MD4 hash of password) in hash:<32 hex digits> format
100 * added support for fallback from abbreviated TLS handshake to
101 full handshake when using EAP-FAST (e.g., due to an expired
103 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
104 draft (draft-ietf-emu-eap-gpsk-07.txt)
105 * added support for drivers that take care of RSN 4-way handshake
106 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
107 WPA_ALG_PMK in set_key)
108 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
109 .config); this version supports only ap_scan=2 mode and allow the
110 driver to take care of the 4-way handshake
111 * fixed a buffer overflow in parsing TSF from scan results when using
112 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
114 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
115 * fixed an integer overflow issue in the ASN.1 parser used by the
116 (experimental) internal TLS implementation to avoid a potential
118 * fixed a race condition with -W option (wait for a control interface
119 monitor before starting) that could have caused the first messages to
121 * added support for processing TNCC-TNCS-Messages to report
122 recommendation (allow/none/isolate) when using TNC [Bug 243]
125 * added network configuration parameter 'frequency' for setting
126 initial channel for IBSS (adhoc) networks
127 * added experimental IEEE 802.11r/D6.0 support
128 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
129 * updated EAP-PSK to use the IANA-allocated EAP type 47
130 * fixed EAP-PAX key derivation
131 * fixed EAP-PSK bit ordering of the Flags field
132 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
133 tunnelled identity request (previously, the identifier from the outer
134 method was used, not the tunnelled identifier which could be
136 * added support for fragmentation of outer TLS packets during Phase 2
137 of EAP-PEAP/TTLS/FAST
138 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
139 * added support for EAP-FAST authentication with inner methods that
140 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
141 for PAC provisioning)
142 * added support for authenticated EAP-FAST provisioning
143 * added support for configuring maximum number of EAP-FAST PACs to
144 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
145 * added support for storing EAP-FAST PACs in binary format
146 (fast_pac_format=binary in phase1 string)
147 * fixed dbus ctrl_iface to validate message interface before
148 dispatching to avoid a possible segfault [Bug 190]
149 * fixed PeerKey key derivation to use the correct PRF label
150 * updated Windows binary build to link against OpenSSL 0.9.8d and
151 added support for EAP-FAST
152 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
153 draft (draft-ietf-emu-eap-gpsk-04.txt)
154 * fixed EAP-AKA Notification processing to allow Notification to be
155 processed after AKA Challenge response has been sent
156 * updated to use IEEE 802.11w/D2.0 for management frame protection
158 * fixed EAP-TTLS implementation not to crash on use of freed memory
159 if TLS library initialization fails
160 * added support for EAP-TNC (Trusted Network Connect)
161 (this version implements the EAP-TNC method and EAP-TTLS changes
162 needed to run two methods in sequence (IF-T) and the IF-IMC and
163 IF-TNCCS interfaces from TNCC)
166 * added experimental, integrated TLSv1 client implementation with the
167 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
168 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
169 .config); this can be useful, e.g., if the target system does not
170 have a suitable TLS library and a minimal code size is required
171 (total size of this internal TLS/crypto code is bit under 50 kB on
172 x86 and the crypto code is shared by rest of the supplicant so some
173 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
174 * removed STAKey handshake since PeerKey handshake has replaced it in
175 IEEE 802.11ma and there are no known deployments of STAKey
176 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
177 draft (draft-ietf-emu-eap-gpsk-01.txt)
178 * added preliminary implementation of IEEE 802.11w/D1.0 (management
180 (Note: this requires driver support to work properly.)
181 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
182 * fixed Windows named pipes ctrl_iface to not stop listening for
183 commands if client program opens a named pipe and closes it
184 immediately without sending a command
185 * fixed USIM PIN status determination for the case that PIN is not
186 needed (this allows EAP-AKA to be used with USIM cards that do not
188 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
189 be used with cards that do not support file selection based on
191 * added support for matching the subjectAltName of the authentication
192 server certificate against multiple name components (e.g.,
193 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
194 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
195 affects IEEE 802.1X with dynamic WEP keys)
196 * changed ctrl_iface network configuration 'get' operations to not
197 return password/key material; if these fields are requested, "*"
198 will be returned if the password/key is set, but the value of the
199 parameter is not exposed
202 * added support for building Windows version with UNICODE defined
203 (wide-char functions)
204 * driver_ndis: fixed static WEP configuration to avoid race condition
205 issues with some NDIS drivers between association and setting WEP
207 * driver_ndis: added validation for IELength value in scan results to
208 avoid crashes when using buggy NDIS drivers [Bug 165]
209 * fixed Release|Win32 target in the Visual Studio project files
210 (previously, only Debug|Win32 target was set properly)
211 * changed control interface API call wpa_ctrl_pending() to allow it to
212 return -1 on error (e.g., connection lost); control interface clients
213 will need to make sure that they verify that the value is indeed >0
214 when determining whether there are pending messages
215 * added an alternative control interface backend for Windows targets:
216 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
217 control interface mechanism for Windows builds (previously, UDP to
219 * changed ctrl_interface configuration for UNIX domain sockets:
220 - deprecated ctrl_interface_group variable (it may be removed in
222 - allow both directory and group be configured with ctrl_interface
223 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
224 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
225 case when group is not changed
226 * added support for controlling more than one interface per process in
228 * added a workaround for a case where the AP is using unknown address
229 (e.g., MAC address of the wired interface) as the source address for
230 EAPOL-Key frames; previously, that source address was used as the
231 destination for EAPOL-Key frames and in key derivation; now, BSSID is
232 used even if the source address does not match with it
233 (this resolves an interoperability issue with Thomson SpeedTouch 580)
234 * added a workaround for UDP-based control interface (which was used in
235 Windows builds before this release) to prevent packets with forged
236 addresses from being accepted as local control requests
237 * removed ndis_events.cpp and possibility of using external
238 ndis_events.exe; C version (ndis_events.c) is fully functional and
239 there is no desire to maintain two separate versions of this
241 * ndis_events: Changed NDIS event notification design to use WMI to
242 learn the adapter description through Win32_PnPEntity class; this
243 should fix some cases where the adapter name was not recognized
244 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
246 * fixed selection of the first network in ap_scan=2 mode; previously,
247 wpa_supplicant could get stuck in SCANNING state when only the first
248 network for enabled (e.g., after 'wpa_cli select_network 0')
249 * winsvc: added support for configuring ctrl_interface parameters in
250 registry (ctrl_interface string value in
251 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
252 required to enable control interface (previously, this was hardcoded
254 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
255 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
258 * fixed build with CONFIG_STAKEY=y [Bug 143]
259 * added support for doing MLME (IEEE 802.11 management frame
260 processing) in wpa_supplicant when using Devicescape IEEE 802.11
261 stack (wireless-dev.git tree)
262 * added a new network block configuration option, fragment_size, to
263 configure the maximum EAP fragment size
264 * driver_ndis: Disable WZC automatically for the selected interface to
265 avoid conflicts with two programs trying to control the radio; WZC
266 will be re-enabled (if it was enabled originally) when wpa_supplicant
268 * added an experimental TLSv1 client implementation
269 (CONFIG_TLS=internal) that can be used instead of an external TLS
270 library, e.g., to reduce total size requirement on systems that do
271 not include any TLS library by default (this is not yet complete;
272 basic functionality is there, but certificate validation is not yet
274 * added PeerKey handshake implementation for IEEE 802.11e
275 direct link setup (DLS) to replace STAKey handshake
276 * fixed WPA PSK update through ctrl_iface for the case where the old
277 PSK was derived from an ASCII passphrase and the new PSK is set as
278 a raw PSK (hex string)
279 * added new configuration option for identifying which network block
280 was used (id_str in wpa_supplicant.conf; included on
281 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
282 variable in wpa_cli action scripts; in addition WPA_ID variable is
283 set to the current unique identifier that wpa_supplicant assigned
284 automatically for the network and that can be used with
285 GET_NETWORK/SET_NETWORK ctrl_iface commands)
286 * wpa_cli action script is now called only when the connect/disconnect
287 status changes or when associating with a different network
288 * fixed configuration parser not to remove CCMP from group cipher list
289 if WPA-None (adhoc) is used (pairwise=NONE in that case)
290 * fixed integrated NDIS events processing not to hang the process due
291 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
292 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
293 draft-clancy-emu-eap-shared-secret-00.txt)
294 * added Microsoft Visual Studio 2005 solution and project files for
295 build wpa_supplicant for Windows (see vs2005 subdirectory)
296 * eloop_win: fixed unregistration of Windows events
297 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
298 at the end of RSN pre-authentication and added unregistration of
299 a Windows event to avoid getting eloop_win stuck with an invalid
301 * driver_ndis: added support for selecting AP based on BSSID
302 * added new environmental variable for wpa_cli action scripts:
303 WPA_CTRL_DIR is the current control interface directory
304 * driver_ndis: added support for using NDISUIO instead of WinPcap for
305 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
306 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
307 wpa_supplicant without requiring WinPcap; note that using NDISUIO
308 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
309 only one application to open the device
310 * changed NDIS driver naming to only include device GUID, e.g.,
311 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
312 specific \Device\NPF_ prefix before the GUID; the prefix is still
313 allowed for backwards compatibility, but it is not required anymore
314 when specifying the interface
315 * driver_ndis: re-initialize driver interface is the adapter is removed
316 and re-inserted [Bug 159]
317 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
318 big endian hosts [Bug 146]
321 * fixed EAP-GTC response to include correct user identity when run as
322 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
323 * driver_ndis: Fixed encryption mode configuration for unencrypted
324 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
325 refused to associate with open networks) [Bug 106]
326 * driver_ndis: use BSSID OID polling to detect when IBSS network is
327 formed even when ndis_events code is included since some NDIS drivers
328 do not generate media connect events in IBSS mode
329 * config_winreg: allow global ctrl_interface parameter to be configured
331 * config_winreg: added support for saving configuration data into
333 * added support for controlling network device operational state
334 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
335 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
336 that can use this information)
337 * driver_wext: added support for WE-21 change to SSID configuration
338 * driver_wext: fixed privacy configuration for static WEP keys mode
340 * added an optional driver_ops callback for MLME-SETPROTECTION.request
342 * added support for EAP-SAKE (no EAP method number allocated yet, so
343 this is using the same experimental type 255 as EAP-PSK)
344 * added support for dynamically loading EAP methods (.so files) instead
345 of requiring them to be statically linked in; this is disabled by
346 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
350 * do not try to use USIM APDUs when initializing PC/SC for SIM card
351 access for a network that has not enabled EAP-AKA
352 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
353 v0.5.1 due to the new support for expanded EAP types)
354 * added support for generating EAP Expanded Nak
355 * try to fetch scan results once before requesting new scan when
356 starting up in ap_scan=1 mode (this can speed up initial association
357 a lot with, e.g., madwifi-ng driver)
358 * added support for receiving EAPOL frames from a Linux bridge
359 interface (-bbr0 on command line)
360 * fixed EAPOL re-authentication for sessions that used PMKSA caching
361 * changed EAP method registration to use a dynamic list of methods
362 instead of a static list generated at build time
363 * fixed PMKSA cache deinitialization not to use freed memory when
364 removing PMKSA entries
365 * fixed a memory leak in EAP-TTLS re-authentication
366 * reject WPA/WPA2 message 3/4 if it does not include any valid
368 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
369 if the driver does not support SIOCSIWAUTH
372 * driver_test: added better support for multiple APs and STAs by using
373 a directory with sockets that include MAC address for each device in
374 the name (driver_param=test_dir=/tmp/test)
375 * added support for EAP expanded type (vendor specific EAP methods)
376 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
377 option can be changed if needed
378 * wpa_cli/wpa_gui: skip non-socket files in control directory when
379 using UNIX domain sockets; this avoids selecting an incorrect
380 interface (e.g., a PID file could be in this directory, even though
381 use of this directory for something else than socket files is not
383 * fixed TLS library deinitialization after RSN pre-authentication not
384 to disable TLS library for normal authentication
385 * driver_wext: Remove null-termination from SSID length if the driver
386 used it; some Linux drivers do this and they were causing problems in
387 wpa_supplicant not finding matching configuration block. This change
388 would break a case where the SSID actually ends in '\0', but that is
389 not likely to happen in real use.
390 * fixed PMKSA cache processing not to trigger deauthentication if the
391 current PMKSA cache entry is replaced with a valid new entry
392 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
393 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
396 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
397 * added experimental STAKey handshake implementation for IEEE 802.11e
398 direct link setup (DLS); note: this is disabled by default in both
399 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
401 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
402 decrypt AT_ENCR_DATA attributes correctly
403 * fixed EAP-AKA to allow resynchronization within the same session
404 * made code closer to ANSI C89 standard to make it easier to port to
405 other C libraries and compilers
406 * started moving operating system or C library specific functions into
407 wrapper functions defined in os.h and implemented in os_*.c to make
409 * wpa_supplicant can now be built with Microsoft Visual C++
410 (e.g., with the freely available Toolkit 2003 version or Visual
411 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
412 example makefile for nmake
413 * added support for using Windows registry for command line parameters
414 (CONFIG_MAIN=main_winsvc) and configuration data
415 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
416 contents; this version can be run both as a Windows service and as a
417 normal application; 'wpasvc.exe app' to start as applicant,
418 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
419 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
421 * made it possible to link ndis_events.exe functionality into
422 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
423 * added better support for multiple control interface backends
424 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
425 * fixed PC/SC code to use correct length for GSM AUTH command buffer
426 and to not use pioRecvPci with SCardTransmit() calls; these were not
427 causing visible problems with pcsc-lite, but Windows Winscard.dll
428 refused the previously used parameters; this fixes EAP-SIM and
429 EAP-AKA authentication using SIM/USIM card under Windows
430 * added new event loop implementation for Windows using
431 WaitForMultipleObject() instead of select() in order to allow waiting
432 for non-socket objects; this can be selected with
433 CONFIG_ELOOP=eloop_win in .config
434 * added support for selecting l2_packet implementation in .config
435 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
436 winpcap, freebsd, none)
437 * added new l2_packet implementation for WinPcap
438 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
439 reduce latency in EAPOL receive processing from about 100 ms to about
441 * added support for EAP-FAST key derivation using other ciphers than
442 RC4-128-SHA for authentication and AES128-SHA for provisioning
443 * added support for configuring CA certificate as DER file and as a
445 * fixed private key configuration as configuration blob and added
446 support for using PKCS#12 as a blob
447 * tls_gnutls: added support for using PKCS#12 files; added support for
449 * added support for loading trusted CA certificates from Windows
450 certificate store: ca_cert="cert_store://<name>", where <name> is
451 likely CA (Intermediate CA certificates) or ROOT (root certificates)
452 * added C version of ndis_events.cpp and made it possible to build this
453 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
454 easily on cross-compilation builds
455 * added wpasvc.exe into Windows binary release; this is an alternative
456 version of wpa_supplicant.exe with configuration backend using
457 Windows registry and with the entry point designed to run as a
459 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
460 wpasvc.exe and removed this additional tool from the Windows binary
461 release since it is not needed anymore
462 * load winscard.dll functions dynamically when building with MinGW
463 since MinGW does not yet include winscard library
465 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
466 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
467 and WinPcap to receive frames sent to PAE group address
468 * disable EAP state machine when IEEE 802.1X authentication is not used
469 in order to get rid of bogus "EAP failed" messages
470 * fixed OpenSSL error reporting to go through all pending errors to
471 avoid confusing reports of old errors being reported at later point
473 * fixed configuration file updating to not write empty variables
474 (e.g., proto or key_mgmt) that the file parser would not accept
475 * fixed ADD_NETWORK ctrl_iface command to use the same default values
476 for variables as empty network definitions read from config file
478 * fixed EAP state machine to not discard EAP-Failure messages in many
479 cases (e.g., during TLS handshake)
480 * fixed a infinite loop in private key reading if the configured file
481 cannot be parsed successfully
482 * driver_madwifi: added support for madwifi-ng
483 * wpa_gui: do not display password/PSK field contents
484 * wpa_gui: added CA certificate configuration
485 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
486 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
487 the new AP is using different WPA/RSN IE
488 * use longer timeout for IEEE 802.11 association to avoid problems with
489 drivers that may take more than five second to associate
492 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
493 RSN IE, but WPA IE would match with wpa_supplicant configuration
494 * added support for named configuration blobs in order to avoid having
495 to use file system for external files (e.g., certificates);
496 variables can be set to "blob://<blob name>" instead of file path to
497 use a named blob; supported fields: pac_file, client_cert,
499 * fixed RSN pre-authentication (it was broken in the clean up of WPA
500 state machine interface in v0.4.5)
501 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
502 sure the driver configures broadcast decryption correctly
503 * added ca_path (and ca_path2) configuration variables that can be used
504 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
505 system-wide trusted CA list
506 * added support for starting wpa_supplicant without a configuration
507 file (-C argument must be used to set ctrl_interface parameter for
508 this case; in addition, -p argument can be used to provide
509 driver_param; these new arguments can also be used with a
510 configuration to override the values from the configuration)
511 * added global control interface that can be optionally used for adding
512 and removing network interfaces dynamically (-g command line argument
513 for both wpa_supplicant and wpa_cli) without having to restart
514 wpa_supplicant process
516 - try to save configuration whenever something is modified
517 - added WEP key configuration
518 - added possibility to edit the current network configuration
519 * driver_ndis: fixed driver polling not to increase frequency on each
520 received EAPOL frame due to incorrectly cancelled timeout
521 * added simple configuration file examples (in examples subdirectory)
522 * fixed driver_wext.c to filter wireless events based on ifindex to
523 avoid interfaces receiving events from other interfaces
524 * delay sending initial EAPOL-Start couple of seconds to speed up
525 authentication for the most common case of Authenticator starting
526 EAP authentication immediately after association
529 * added a workaround for clearing keys with ndiswrapper to allow
530 roaming from WPA enabled AP to plaintext one
531 * added docbook documentation (doc/docbook) that can be used to
532 generate, e.g., man pages
533 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
534 PF_PACKET in order to prepare for network devices that do not use
535 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
536 * use receipt of EAPOL-Key frame as a lower layer success indication
537 for EAP state machine to allow recovery from dropped EAP-Success
539 * cleaned up internal EAPOL frame processing by not including link
540 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
541 header is added only when transmitted the frame; this makes it easier
542 to use wpa_supplicant on link layers that use different header than
544 * updated EAP-PSK to use draft 9 by default since this can now be
545 tested with hostapd; removed support for draft 3, including
546 server_nai configuration option from network blocks
547 * driver_wired: add PAE address to the multicast address list in order
548 to be able to receive EAPOL frames with drivers that do not include
549 these multicast addresses by default
550 * driver_wext: add support for WE-19
551 * added support for multiple configuration backends (CONFIG_BACKEND
552 option); currently, only 'file' is supported (i.e., the format used
553 in wpa_supplicant.conf)
554 * added support for updating configuration ('wpa_cli save_config');
555 this is disabled by default and can be enabled with global
556 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
557 and wpa_gui to store the configuration changes in a permanent store
558 * added GET_NETWORK ctrl_iface command
559 (e.g., 'wpa_cli get_network 0 ssid')
562 * replaced OpenSSL patch for EAP-FAST support
563 (openssl-tls-extensions.patch) with a more generic and correct
564 patch (the new patch is not compatible with the previous one, so the
565 OpenSSL library will need to be patched with the new patch in order
566 to be able to build wpa_supplicant with EAP-FAST support)
567 * added support for using Windows certificate store (through CryptoAPI)
568 for client certificate and private key operations (EAP-TLS)
569 (see wpa_supplicant.conf for more information on how to configure
570 this with private_key)
571 * ported wpa_gui to Windows
572 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
573 built with the open source version of the Qt4 for Windows
574 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
575 with drivers that do not support WPA
576 * ndis_events: fixed Windows 2000 support
577 * added support for enabling/disabling networks from the list of all
578 configured networks ('wpa_cli enable_network <network id>' and
579 'wpa_cli disable_network <network id>')
580 * added support for adding and removing network from the current
581 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
582 <network id>'); added networks are disabled by default and they can
583 be enabled with enable_network command once the configuration is done
584 for the new network; note: configuration file is not yet updated, so
585 these new networks are lost when wpa_supplicant is restarted
586 * added support for setting network configuration parameters through
587 the control interface, for example:
588 wpa_cli set_network 0 ssid "\"my network\""
589 * fixed parsing of strings that include both " and # within double
590 quoted area (e.g., "start"#end")
591 * added EAP workaround for PEAP session resumption: allow outer,
592 i.e., not tunneled, EAP-Success to terminate session since; this can
593 be disabled with eap_workaround=0
594 (this was allowed for PEAPv1 before, but now it is also allowed for
595 PEAPv0 since at least one RADIUS authentication server seems to be
596 doing this for PEAPv0, too)
597 * wpa_gui: added preliminary support for adding new networks to the
598 wpa_supplicant configuration (double click on the scan results to
599 open network configuration)
602 * removed interface for external EAPOL/EAP supplicant (e.g.,
603 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
604 anymore and is unlikely to be used by anyone
605 * driver_ndis: fixed WinPcap 3.0 support
606 * fixed build with CONFIG_DNET_PCAP=y on Linux
607 * l2_packet: moved different implementations into separate files
611 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
612 (note: ipw2100-1.1.0 is likely to require an update to work with
614 * added support for using ap_scan=2 mode with multiple network blocks;
615 wpa_supplicant will go through the networks one by one until the
616 driver reports a successful association; this uses the same order for
617 networks as scan_ssid=1 scans, i.e., the priority field is ignored
618 and the network block order in the file is used instead
619 * fixed a potential issue in RSN pre-authentication ending up using
620 freed memory if pre-authentication times out
621 * added support for matching alternative subject name extensions of the
622 authentication server certificate; new configuration variables
623 altsubject_match and altsubject_match2
624 * driver_ndis: added support for IEEE 802.1X authentication with wired
626 * added support for querying private key password (EAP-TLS) through the
627 control interface (wpa_cli/wpa_gui) if one is not included in the
629 * driver_broadcom: fixed couple of memory leaks in scan result
631 * EAP-PAX is now registered as EAP type 46
632 * fixed EAP-PAX MAC calculation
633 * fixed EAP-PAX CK and ICK key derivation
634 * added support for using password with EAP-PAX (as an alternative to
635 entering key with eappsk); SHA-1 hash of the password will be used as
637 * added support for arbitrary driver interface parameters through the
638 configuration file with a new driver_param field; this adds a new
639 driver_ops function set_param()
640 * added possibility to override l2_packet module with driver interface
641 API (new send_eapol handler); this can be used to implement driver
642 specific TX/RX functions for EAPOL frames
643 * fixed ctrl_interface_group processing for the case where gid is
644 entered as a number, not group name
645 * driver_test: added support for testing hostapd with wpa_supplicant
646 by using test driver interface without any kernel drivers or network
650 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
651 packets to be encrypted; this was apparently broken by the changed
652 ioctl order in v0.4.0
653 * driver_madwifi: added preliminary support for compiling against 'BSD'
654 branch of madwifi CVS tree
655 * added support for EAP-MSCHAPv2 password retries within the same EAP
656 authentication session
657 * added support for password changes with EAP-MSCHAPv2 (used when the
658 password has expired)
659 * added support for reading additional certificates from PKCS#12 files
660 and adding them to the certificate chain
661 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
663 * fixed a possible double free in EAP-TTLS fast-reauthentication when
664 identity or password is entered through control interface
665 * display EAP Notification messages to user through control interface
666 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
667 * added GUI version of wpa_cli, wpa_gui; this is not build
668 automatically with 'make'; use 'make wpa_gui' to build (this requires
669 Qt development tools)
670 * added 'disconnect' command to control interface for setting
671 wpa_supplicant in state where it will not associate before
672 'reassociate' command has been used
673 * added support for selecting a network from the list of all configured
674 networks ('wpa_cli select_network <network id>'; this disabled all
675 other networks; to re-enable, 'wpa_cli select_network any')
676 * added support for getting scan results through control interface
677 * added EAP workaround for PEAPv1 session resumption: allow outer,
678 i.e., not tunneled, EAP-Success to terminate session since; this can
679 be disabled with eap_workaround=0
681 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
682 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
683 used to reduce the size of the wpa_supplicant considerably if
684 debugging code is not needed
685 * fixed EAPOL-Key validation to drop packets with invalid Key Data
686 Length; such frames could have crashed wpa_supplicant due to buffer
688 * added support for wired authentication (IEEE 802.1X on wired
689 Ethernet); driver interface 'wired'
690 * obsoleted set_wpa() handler in the driver interface API (it can be
691 replaced by moving enable/disable functionality into init()/deinit())
692 (calls to set_wpa() are still present for backwards compatibility,
693 but they may be removed in the future)
694 * driver_madwifi: fixed association in plaintext mode
695 * modified the EAP workaround that accepts EAP-Success with incorrect
696 Identifier to be even less strict about verification in order to
697 interoperate with some authentication servers
698 * added support for sending TLS alerts
699 * added support for 'any' SSID wildcard; if ssid is not configured or
700 is set to an empty string, any SSID will be accepted for non-WPA AP
701 * added support for asking PIN (for SIM) from frontends (e.g.,
702 wpa_cli); if a PIN is needed, but not included in the configuration
703 file, a control interface request is sent and EAP processing is
704 delayed until the PIN is available
705 * added support for using external devices (e.g., a smartcard) for
706 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
707 new wpa_supplicant.conf variables:
708 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
709 - network: engine, engine_id, key_id
710 * added experimental support for EAP-PAX
711 * added monitor mode for wpa_cli (-a<path to a program to run>) that
712 allows external commands (e.g., shell scripts) to be run based on
713 wpa_supplicant events, e.g., when authentication has been completed
714 and data connection is ready; other related wpa_cli arguments:
715 -B (run in background), -P (write PID file); wpa_supplicant has a new
716 command line argument (-W) that can be used to make it wait until a
717 control interface command is received in order to avoid missing
719 * added support for opportunistic WPA2 PMKSA key caching (disabled by
720 default, can be enabled with proactive_key_caching=1)
721 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
722 Authenticator rejects PMKSA caching attempt and the driver is not
723 using assoc_info events
724 * added -P<pid file> argument for wpa_supplicant to write the current
725 process id into a file
727 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
728 * added new phase1 option parameter, include_tls_length=1, to force
729 wpa_supplicant to add TLS Message Length field to all TLS messages
730 even if the packet is not fragmented; this may be needed with some
731 authentication servers
732 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
733 using drivers that take care of AP selection (e.g., when using
735 * fixed reprocessing of pending request after ctrl_iface requests for
736 identity/password/otp
737 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
738 EAP-PEAP and EAP-TTLS
739 * all drivers using driver_wext: set interface up and select Managed
740 mode when starting wpa_supplicant; set interface down when exiting
741 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
742 ipw2100 and ipw2200; please note that this also changed the
743 configuration variable in .config to CONFIG_DRIVER_IPW
746 * fixed a busy loop introduced in v0.3.5 for scan result processing
747 when no matching AP is found
750 * added a workaround for an interoperability issue with a Cisco AP
752 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
753 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
754 retransmission of dropped frames)
755 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
756 (e.g., segfault when processing EAPOL-Key frames)
757 * fixed EAP workaround and fast reauthentication configuration for
758 RSN pre-authentication; previously these were disabled and
759 pre-authentication would fail if the used authentication server
760 requires EAP workarounds
761 * added support for blacklisting APs that fail or timeout
762 authentication in ap_scan=1 mode so that all APs are tried in cases
763 where the ones with strongest signal level are failing authentication
764 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
765 authentication attempt
766 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
767 in the previous authentication (previously, only Phase 1 success was
771 * added preliminary support for IBSS (ad-hoc) mode configuration
772 (mode=1 in network block); this included a new key_mgmt mode
773 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
774 key management; see wpa_supplicant.conf for more details and an
775 example on how to configure this (note: this is currently implemented
776 only for driver_hostapd.c, but the changes should be trivial to add
777 in associate() handler for other drivers, too (assuming the driver
779 * added preliminary port for native Windows (i.e., no cygwin) using
783 * added optional support for GNU Readline and History Libraries for
784 wpa_cli (CONFIG_READLINE)
785 * cleaned up EAP state machine <-> method interface and number of
786 small problems with error case processing not terminating on
787 EAP-Failure but waiting for timeout
788 * added couple of workarounds for interoperability issues with a
789 Cisco AP when using WPA2
790 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
791 Note: This requires a patch for openssl to add support for TLS
792 extensions and number of workarounds for operations without
793 certificates. Proof of concept type of experimental patch is
794 included in openssl-tls-extensions.patch.
797 * fixed private key loading for cases where passphrase is not set
798 * fixed Windows/cygwin L2 packet handler freeing; previous version
799 could cause a segfault when RSN pre-authentication was completed
800 * added support for PMKSA caching with drivers that generate RSN IEs
801 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
802 but similar code can be easily added to driver_ndiswrapper.c once
803 ndiswrapper gets full support for RSN PMKSA caching
804 * improved recovery from PMKID mismatches by requesting full EAP
805 authentication in case of failed PMKSA caching attempt
806 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
807 (this requires that ndis_events is ran while wpa_supplicant is
809 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
810 * added support for driver interfaces to replace the interface name
811 based on driver/OS specific mapping, e.g., in case of driver_ndis,
812 this allows the beginning of the adapter description to be used as
814 * added support for CR+LF (Windows-style) line ends in configuration
816 * driver_ndis: enable radio before starting scanning, disable radio
818 * modified association event handler to set portEnabled = FALSE before
819 clearing port Valid in order to reset EAP state machine and avoid
820 problems with new authentication getting ignored because of state
821 machines ending up in AUTHENTICATED/SUCCESS state based on old
823 * added support for driver events to add PMKID candidates in order to
824 allow drivers to give priority to most likely roaming candidates
825 * driver_hostap: moved PrivacyInvoked configuration to associate()
826 function so that this will not be set for plaintext connections
827 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
828 interface can distinguish plaintext and IEEE 802.1X (no WPA)
830 * fixed static WEP key configuration to use broadcast/default type for
831 all keys (previously, the default TX key was configured as pairwise/
833 * driver_ndis: added legacy WPA capability detection for non-WPA2
835 * added support for setting static WEP keys for IEEE 802.1X without
836 dynamic WEP keying (eapol_flags=0)
839 * added support for reading PKCS#12 (PFX) files (as a replacement for
840 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
841 * fixed compilation with CONFIG_PCSC=y
842 * added new ap_scan mode, ap_scan=2, for drivers that take care of
843 association, but need to be configured with security policy and SSID,
844 e.g., ndiswrapper and NDIS driver; this mode should allow such
845 drivers to work with hidden SSIDs and optimized roaming; when
846 ap_scan=2 is used, only the first network block in the configuration
847 file is used and this configuration should have explicit security
848 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
849 group, proto variables
850 * added experimental port of wpa_supplicant for Windows
851 - driver_ndis.c driver interface (NDIS OIDs)
852 - currently, this requires cygwin and WinPcap
853 - small utility, win_if_list, can be used to get interface name
854 * control interface can now be removed at build time; add
855 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
856 * optional Xsupplicant interface can now be removed at build time;
857 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
858 * added auth_alg to driver interface associate() parameters to make it
859 easier for drivers to configure authentication algorithm as part of
862 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
863 * driver_broadcom: added new driver interface for Broadcom wl.o driver
864 (a generic driver for Broadcom IEEE 802.11a/g cards)
865 * wpa_cli: fixed parsing of -p <path> command line argument
866 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
867 ACK, not tunneled EAP-Success (of which only the first byte was
868 actually send due to a bug in previous code); this seems to
869 interoperate with most RADIUS servers that implements PEAPv1
870 * PEAPv1: added support for terminating PEAP authentication on tunneled
871 EAP-Success message; this can be configured by adding
872 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
873 (some RADIUS servers require this whereas others require a tunneled
875 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
876 the old label for key derivation; previously, the default was 1,
877 but it looks like most existing PEAPv1 implementations use the old
878 label which is thus more suitable default option
879 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
880 * fixed parsing of wep_tx_keyidx
881 * added support for configuring list of allowed Phase 2 EAP types
882 (for both EAP-PEAP and EAP-TTLS) instead of only one type
883 * added support for configuring IEEE 802.11 authentication algorithm
884 (auth_alg; mainly for using Shared Key authentication with static
886 * added support for EAP-AKA (with UMTS SIM)
887 * fixed couple of errors in PCSC handling that could have caused
888 random-looking errors for EAP-SIM
889 * added support for EAP-SIM pseudonyms and fast re-authentication
890 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
892 * added support for EAP-SIM with two challanges
893 (phase1="sim_min_num_chal=3" can be used to require three challenges)
894 * added support for configuring DH/DSA parameters for an ephemeral DH
895 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
896 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
897 and optional DH key exchange to achieve forward secracy with RSA keys
898 * added support for matching subject of the authentication server
899 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
900 configuration variables subject_match and subject_match2
901 * changed SSID configuration in driver_wext.c (used by many driver
902 interfaces) to use ssid_len+1 as the length for SSID since some Linux
904 * fixed couple of unaligned reads in scan result parsing to fix WPA
905 connection on some platforms (e.g., ARM)
906 * added driver interface for Intel ipw2100 driver
907 * added support for LEAP with WPA
908 * added support for larger scan results report (old limit was 4 kB of
909 data, i.e., about 35 or so APs) when using Linux wireless extensions
911 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
912 only if there is a PMKSA cache entry for the current AP
913 * fixed error handling for case where reading of scan results fails:
914 must schedule a new scan or wpa_supplicant will remain waiting
916 * changed debug output to remove shared password/key material by
917 default; all key information can be included with -K command line
918 argument to match the previous behavior
919 * added support for timestamping debug log messages (disabled by
920 default, can be enabled with -t command line argument)
921 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
922 if keys are not configured to be used; this fixes IEEE 802.1X mode
923 with drivers that use this information to configure whether Privacy
924 bit can be in Beacon frames (e.g., ndiswrapper)
925 * avoid clearing driver keys if no keys have been configured since last
926 key clear request; this seems to improve reliability of group key
927 handshake for ndiswrapper & NDIS driver which seems to be suffering
928 of some kind of timing issue when the keys are cleared again after
930 * changed driver interface API:
931 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
932 version is being used (now, this is set to 2; previously, it was
934 - pass pointer to private data structure to all calls
935 - the new API is not backwards compatible; all in-tree driver
936 interfaces has been converted to the new API
937 * added support for controlling multiple interfaces (radios) per
938 wpa_supplicant process; each interface needs to be listed on the
939 command line (-c, -i, -D arguments) with -N as a separator
940 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
941 * added a workaround for EAP servers that incorrectly use same Id for
942 sequential EAP packets
943 * changed libpcap/libdnet configuration to use .config variable,
944 CONFIG_DNET_PCAP, instead of requiring Makefile modification
945 * improved downgrade attack detection in IE verification of msg 3/4:
946 verify both WPA and RSN IEs, if present, not only the selected one;
947 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
948 Probe Response frame, and RSN is enabled in wpa_supplicant
950 * fixed WPA msg 3/4 processing to allow Key Data field contain other
951 IEs than just one WPA IE
952 * added support for FreeBSD and driver interface for the BSD net80211
953 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
954 required kernel mods have not yet been committed
955 * made EAP workarounds configurable; enabled by default, can be
956 disabled with network block option eap_workaround=0
958 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
959 * resolved couple of interoperability issues with EAP-PEAPv1 and
960 Phase 2 (inner EAP) fragment reassembly
961 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
962 AP is using non-zero key index for the unicast key and key index zero
963 for the broadcast key
964 * driver_hostap: fixed IEEE 802.1X WEP key updates and
965 re-authentication by allowing unencrypted EAPOL frames when not using
967 * added a new driver interface, 'wext', which uses only standard,
968 driver independent functionality in Linux wireless extensions;
969 currently, this can be used only for non-WPA IEEE 802.1X mode, but
970 eventually, this is to be extended to support full WPA/WPA2 once
971 Linux wireless extensions get support for this
972 * added support for mode in which the driver is responsible for AP
973 scanning and selection; this is disabled by default and can be
974 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
975 this mode can be used, e.g., with generic 'wext' driver interface to
976 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
977 supporting wireless extensions.
978 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
979 operation with an AP that does not include SSID in the Beacon frames)
980 * added support for new EAP authentication methods:
981 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
982 * added support for asking one-time-passwords from frontends (e.g.,
983 wpa_cli); this 'otp' command works otherwise like 'password' command,
984 but the password is used only once and the frontend will be asked for
985 a new password whenever a request from authenticator requires a
986 password; this can be used with both EAP-OTP and EAP-GTC
987 * changed wpa_cli to automatically re-establish connection so that it
988 does not need to be re-started when wpa_supplicant is terminated and
990 * improved user data (identity/password/otp) requests through
991 frontends: process pending EAPOL packets after getting new
992 information so that full authentication does not need to be
993 restarted; in addition, send pending requests again whenever a new
995 * changed control frontends to use a new directory for socket files to
996 make it easier for wpa_cli to automatically select between interfaces
997 and to provide access control for the control interface;
998 wpa_supplicant.conf: ctrl_interface is now a path
999 (/var/run/wpa_supplicant is the recommended path) and
1000 ctrl_interface_group can be used to select which group gets access to
1001 the control interface;
1002 wpa_cli: by default, try to connect to the first interface available
1003 in /var/run/wpa_supplicant; this path can be overriden with -p option
1004 and an interface can be selected with -i option (i.e., in most common
1005 cases, wpa_cli does not need to get any arguments)
1006 * added support for LEAP
1007 * added driver interface for Linux ndiswrapper
1008 * added priority option for network blocks in the configuration file;
1009 this allows networks to be grouped based on priority (the scan
1010 results are searched for matches with network blocks in this order)
1013 * sort scan results to improve AP selection
1014 * fixed control interface socket removal for some error cases
1015 * improved scan requesting and authentication timeout
1016 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1018 * PEAP version can now be forced with phase1="peapver=<ver>"
1019 (mostly for testing; by default, the highest version supported by
1020 both the Supplicant and Authentication Server is selected
1022 * added support for madwifi driver (Atheros ar521x)
1023 * added a workaround for cases where AP sets Install Tx/Rx bit for
1024 WPA Group Key messages when pairwise keys are used (without this,
1025 the Group Key would be used for Tx and the AP would drop frames
1027 * added GSM SIM/USIM interface for GSM authentication algorithm for
1028 EAP-SIM; this requires pcsc-lite
1029 * added support for ATMEL AT76C5XXx driver
1030 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1031 does not include key data in the EAPOL-Key frame (i.e., part of
1032 EAP keying material is used as data encryption key)
1033 * added support for using plaintext and static WEP networks
1037 * added support for new EAP authentication methods:
1038 EAP-TTLS/EAP-MD5-Challenge
1040 EAP-TTLS/EAP-MSCHAPv2
1048 EAP-PEAP/MD5-Challenge
1050 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1051 * added support for anonymous identity (to be used when identity is
1052 sent in plaintext; real identity will be used within TLS protected
1053 tunnel (e.g., with EAP-TTLS)
1054 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1055 * added support for requesting identity and password information using
1056 control interface; in other words, the password for EAP-PEAP or
1057 EAP-TTLS does not need to be included in the configuration file since
1058 a frontand (e.g., wpa_cli) can ask it from the user
1059 * improved RSN pre-authentication to use a candidate list and process
1060 all candidates from each scan; not only one per scan
1061 * fixed RSN IE and WPA IE capabilities field parsing
1062 * ignore Tx bit in GTK IE when Pairwise keys are used
1063 * avoid making new scan requests during IEEE 802.1X negotiation
1064 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1065 with TLS support (this replaces the included implementation with
1066 library code to save about 8 kB since the library code is needed
1068 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1069 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1072 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1074 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1075 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1076 - EAP-MD5 (cannot be used with WPA-RADIUS)
1077 [draft-ietf-eap-rfc2284bis-09.txt]
1078 - EAP-TLS [RFC 2716]
1079 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1080 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1081 [draft-kamath-pppext-eap-mschapv2-00.txt]
1082 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1083 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1084 - new configuration file options: eap, identity, password, ca_cert,
1085 client_cert, privatekey, private_key_passwd
1086 - Xsupplicant is not required anymore, but it can be used by
1087 disabling the internal IEEE 802.1X Supplicant with -e command line
1089 - this code is not included in the default build; Makefile need to
1090 be edited for this (uncomment lines for selected functionality)
1091 - EAP-TLS and EAP-PEAP require openssl libraries
1092 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1093 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1094 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1095 EAPOL-Key frames instead of WPA key handshakes)
1096 * added support for IEEE 802.11i/RSN (WPA2)
1097 - improved PTK Key Handshake
1098 - PMKSA caching, pre-authentication
1099 * fixed wpa_supplicant to ignore possible extra data after WPA
1100 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1101 TPTK' error from message 3 of 4-Way Handshake in case the AP
1102 includes extra data after the EAPOL-Key)
1103 * added interface for external programs (frontends) to control
1105 - CLI example (wpa_cli) with interactive mode and command line
1107 - replaced SIGUSR1 status/statistics with the new control interface
1108 * made some feature compile time configurable
1109 - .config file for make
1110 - driver interfaces (hostap, hermes, ..)
1111 - EAPOL/EAP functions
1114 * Initial version of wpa_supplicant
