1 ChangeLog for wpa_supplicant
4 * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
5 (can be used to simulate test SIM/USIM card with a known private key;
6 enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
7 and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
10 * added support for SHA-256 as X.509 certificate digest when using the
11 internal X.509/TLSv1 implementation
12 * updated management frame protection to use IEEE 802.11w/D6.0
13 * added support for using SHA256-based stronger key derivation for WPA2
15 * fixed FT (IEEE 802.11r) authentication after a failed association to
17 * added support for configuring Phase 2 (inner/tunneled) authentication
18 method with wpa_gui-qt4
21 * added support for EAP Sequences in EAP-FAST Phase 2
22 * added support for using TNC with EAP-FAST
23 * added driver_ps3 for the PS3 Linux wireless driver
24 * added support for optional cryptobinding with PEAPv0
25 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
26 allow fallback to full handshake if server rejects PAC-Opaque
27 * added fragmentation support for EAP-TNC
28 * added support for parsing PKCS #8 formatted private keys into the
29 internal TLS implementation (both PKCS #1 RSA key and PKCS #8
30 encapsulated RSA key can now be used)
31 * added option of using faster, but larger, routines in the internal
32 LibTomMath (for internal TLS implementation) to speed up DH and RSA
33 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
34 * fixed race condition between disassociation event and group key
35 handshake to avoid getting stuck in incorrect state [Bug 261]
36 * fixed opportunistic key caching (proactive_key_caching)
39 * removed 'nai' and 'eappsk' network configuration variables that were
40 previously used for configuring user identity and key for EAP-PSK,
41 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
42 replacement for 'nai' (if old configuration used a separate
43 'identity' value, that would now be configured as
44 'anonymous_identity'). 'password' field is now used as the
45 replacement for 'eappsk' (it can also be set using hexstring to
46 present random binary data)
47 * removed '-w' command line parameter (wait for interface to be added,
48 if needed); cleaner way of handling this functionality is to use an
49 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
50 when an interface is added
51 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
52 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
53 indicating when new scan results become available
54 * added new ctrl_iface command, BSS, to allow scan results to be
55 fetched without hitting the message size limits (this command
56 can be used to iterate through the scan results one BSS at the time)
57 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
58 attributes in EAP-SIM Start/Response when using fast reauthentication
59 * fixed EAPOL not to end up in infinite loop when processing dynamic
60 WEP keys with IEEE 802.1X
61 * fixed problems in getting NDIS events from WMI on Windows 2000
64 * added support for Makefile builds to include debug-log-to-a-file
65 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
66 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
67 lengths properly to avoid potential crash caused by invalid messages
68 * added data structure for storing allocated buffers (struct wpabuf);
69 this does not affect wpa_supplicant usage, but many of the APIs
70 changed and various interfaces (e.g., EAP) is not compatible with old
72 * added support for protecting EAP-AKA/Identity messages with
73 AT_CHECKCODE (optional feature in RFC 4187)
74 * added support for protected result indication with AT_RESULT_IND for
75 EAP-SIM and EAP-AKA (phase1="result_ind=1")
76 * added driver_wext workaround for race condition between scanning and
77 association with drivers that take very long time to scan all
78 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
79 using a longer hardcoded timeout for the scan if the driver supports
80 notifications for scan completion (SIOCGIWSCAN event); this helps,
81 e.g., in cases where wpa_supplicant and madwifi driver ended up in
82 loop where the driver did not even try to associate
83 * stop EAPOL timer tick when no timers are in use in order to reduce
84 power consumption (no need to wake up the process once per second)
86 * added support for privilege separation (run only minimal part of
87 wpa_supplicant functionality as root and rest as unprivileged,
88 non-root process); see 'Privilege separation' in README for details;
89 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
91 * changed scan results data structure to include all information
92 elements to make it easier to support new IEs; old get_scan_result()
93 driver_ops is still supported for backwards compatibility (results
94 are converted internally to the new format), but all drivers should
95 start using the new get_scan_results2() to make them more likely to
96 work with new features
97 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
98 application, i.e., it does not require Qt3Support anymore; Windows
99 binary of wpa_gui.exe is now from this directory and only requires
100 QtCore4.dll and QtGui4.dll libraries
101 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
102 available as a separate package to make wpa_gui installation easier:
103 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
104 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
105 only shared key/password authentication is supported in this version
108 * added support for configuring password as NtPasswordHash
109 (16-byte MD4 hash of password) in hash:<32 hex digits> format
110 * added support for fallback from abbreviated TLS handshake to
111 full handshake when using EAP-FAST (e.g., due to an expired
113 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
114 draft (draft-ietf-emu-eap-gpsk-07.txt)
115 * added support for drivers that take care of RSN 4-way handshake
116 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
117 WPA_ALG_PMK in set_key)
118 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
119 .config); this version supports only ap_scan=2 mode and allow the
120 driver to take care of the 4-way handshake
121 * fixed a buffer overflow in parsing TSF from scan results when using
122 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
124 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
125 * fixed an integer overflow issue in the ASN.1 parser used by the
126 (experimental) internal TLS implementation to avoid a potential
128 * fixed a race condition with -W option (wait for a control interface
129 monitor before starting) that could have caused the first messages to
131 * added support for processing TNCC-TNCS-Messages to report
132 recommendation (allow/none/isolate) when using TNC [Bug 243]
135 * added network configuration parameter 'frequency' for setting
136 initial channel for IBSS (adhoc) networks
137 * added experimental IEEE 802.11r/D6.0 support
138 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
139 * updated EAP-PSK to use the IANA-allocated EAP type 47
140 * fixed EAP-PAX key derivation
141 * fixed EAP-PSK bit ordering of the Flags field
142 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
143 tunnelled identity request (previously, the identifier from the outer
144 method was used, not the tunnelled identifier which could be
146 * added support for fragmentation of outer TLS packets during Phase 2
147 of EAP-PEAP/TTLS/FAST
148 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
149 * added support for EAP-FAST authentication with inner methods that
150 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
151 for PAC provisioning)
152 * added support for authenticated EAP-FAST provisioning
153 * added support for configuring maximum number of EAP-FAST PACs to
154 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
155 * added support for storing EAP-FAST PACs in binary format
156 (fast_pac_format=binary in phase1 string)
157 * fixed dbus ctrl_iface to validate message interface before
158 dispatching to avoid a possible segfault [Bug 190]
159 * fixed PeerKey key derivation to use the correct PRF label
160 * updated Windows binary build to link against OpenSSL 0.9.8d and
161 added support for EAP-FAST
162 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
163 draft (draft-ietf-emu-eap-gpsk-04.txt)
164 * fixed EAP-AKA Notification processing to allow Notification to be
165 processed after AKA Challenge response has been sent
166 * updated to use IEEE 802.11w/D2.0 for management frame protection
168 * fixed EAP-TTLS implementation not to crash on use of freed memory
169 if TLS library initialization fails
170 * added support for EAP-TNC (Trusted Network Connect)
171 (this version implements the EAP-TNC method and EAP-TTLS changes
172 needed to run two methods in sequence (IF-T) and the IF-IMC and
173 IF-TNCCS interfaces from TNCC)
176 * added experimental, integrated TLSv1 client implementation with the
177 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
178 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
179 .config); this can be useful, e.g., if the target system does not
180 have a suitable TLS library and a minimal code size is required
181 (total size of this internal TLS/crypto code is bit under 50 kB on
182 x86 and the crypto code is shared by rest of the supplicant so some
183 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
184 * removed STAKey handshake since PeerKey handshake has replaced it in
185 IEEE 802.11ma and there are no known deployments of STAKey
186 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
187 draft (draft-ietf-emu-eap-gpsk-01.txt)
188 * added preliminary implementation of IEEE 802.11w/D1.0 (management
190 (Note: this requires driver support to work properly.)
191 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
192 * fixed Windows named pipes ctrl_iface to not stop listening for
193 commands if client program opens a named pipe and closes it
194 immediately without sending a command
195 * fixed USIM PIN status determination for the case that PIN is not
196 needed (this allows EAP-AKA to be used with USIM cards that do not
198 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
199 be used with cards that do not support file selection based on
201 * added support for matching the subjectAltName of the authentication
202 server certificate against multiple name components (e.g.,
203 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
204 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
205 affects IEEE 802.1X with dynamic WEP keys)
206 * changed ctrl_iface network configuration 'get' operations to not
207 return password/key material; if these fields are requested, "*"
208 will be returned if the password/key is set, but the value of the
209 parameter is not exposed
212 * added support for building Windows version with UNICODE defined
213 (wide-char functions)
214 * driver_ndis: fixed static WEP configuration to avoid race condition
215 issues with some NDIS drivers between association and setting WEP
217 * driver_ndis: added validation for IELength value in scan results to
218 avoid crashes when using buggy NDIS drivers [Bug 165]
219 * fixed Release|Win32 target in the Visual Studio project files
220 (previously, only Debug|Win32 target was set properly)
221 * changed control interface API call wpa_ctrl_pending() to allow it to
222 return -1 on error (e.g., connection lost); control interface clients
223 will need to make sure that they verify that the value is indeed >0
224 when determining whether there are pending messages
225 * added an alternative control interface backend for Windows targets:
226 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
227 control interface mechanism for Windows builds (previously, UDP to
229 * changed ctrl_interface configuration for UNIX domain sockets:
230 - deprecated ctrl_interface_group variable (it may be removed in
232 - allow both directory and group be configured with ctrl_interface
233 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
234 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
235 case when group is not changed
236 * added support for controlling more than one interface per process in
238 * added a workaround for a case where the AP is using unknown address
239 (e.g., MAC address of the wired interface) as the source address for
240 EAPOL-Key frames; previously, that source address was used as the
241 destination for EAPOL-Key frames and in key derivation; now, BSSID is
242 used even if the source address does not match with it
243 (this resolves an interoperability issue with Thomson SpeedTouch 580)
244 * added a workaround for UDP-based control interface (which was used in
245 Windows builds before this release) to prevent packets with forged
246 addresses from being accepted as local control requests
247 * removed ndis_events.cpp and possibility of using external
248 ndis_events.exe; C version (ndis_events.c) is fully functional and
249 there is no desire to maintain two separate versions of this
251 * ndis_events: Changed NDIS event notification design to use WMI to
252 learn the adapter description through Win32_PnPEntity class; this
253 should fix some cases where the adapter name was not recognized
254 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
256 * fixed selection of the first network in ap_scan=2 mode; previously,
257 wpa_supplicant could get stuck in SCANNING state when only the first
258 network for enabled (e.g., after 'wpa_cli select_network 0')
259 * winsvc: added support for configuring ctrl_interface parameters in
260 registry (ctrl_interface string value in
261 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
262 required to enable control interface (previously, this was hardcoded
264 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
265 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
268 * fixed build with CONFIG_STAKEY=y [Bug 143]
269 * added support for doing MLME (IEEE 802.11 management frame
270 processing) in wpa_supplicant when using Devicescape IEEE 802.11
271 stack (wireless-dev.git tree)
272 * added a new network block configuration option, fragment_size, to
273 configure the maximum EAP fragment size
274 * driver_ndis: Disable WZC automatically for the selected interface to
275 avoid conflicts with two programs trying to control the radio; WZC
276 will be re-enabled (if it was enabled originally) when wpa_supplicant
278 * added an experimental TLSv1 client implementation
279 (CONFIG_TLS=internal) that can be used instead of an external TLS
280 library, e.g., to reduce total size requirement on systems that do
281 not include any TLS library by default (this is not yet complete;
282 basic functionality is there, but certificate validation is not yet
284 * added PeerKey handshake implementation for IEEE 802.11e
285 direct link setup (DLS) to replace STAKey handshake
286 * fixed WPA PSK update through ctrl_iface for the case where the old
287 PSK was derived from an ASCII passphrase and the new PSK is set as
288 a raw PSK (hex string)
289 * added new configuration option for identifying which network block
290 was used (id_str in wpa_supplicant.conf; included on
291 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
292 variable in wpa_cli action scripts; in addition WPA_ID variable is
293 set to the current unique identifier that wpa_supplicant assigned
294 automatically for the network and that can be used with
295 GET_NETWORK/SET_NETWORK ctrl_iface commands)
296 * wpa_cli action script is now called only when the connect/disconnect
297 status changes or when associating with a different network
298 * fixed configuration parser not to remove CCMP from group cipher list
299 if WPA-None (adhoc) is used (pairwise=NONE in that case)
300 * fixed integrated NDIS events processing not to hang the process due
301 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
302 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
303 draft-clancy-emu-eap-shared-secret-00.txt)
304 * added Microsoft Visual Studio 2005 solution and project files for
305 build wpa_supplicant for Windows (see vs2005 subdirectory)
306 * eloop_win: fixed unregistration of Windows events
307 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
308 at the end of RSN pre-authentication and added unregistration of
309 a Windows event to avoid getting eloop_win stuck with an invalid
311 * driver_ndis: added support for selecting AP based on BSSID
312 * added new environmental variable for wpa_cli action scripts:
313 WPA_CTRL_DIR is the current control interface directory
314 * driver_ndis: added support for using NDISUIO instead of WinPcap for
315 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
316 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
317 wpa_supplicant without requiring WinPcap; note that using NDISUIO
318 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
319 only one application to open the device
320 * changed NDIS driver naming to only include device GUID, e.g.,
321 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
322 specific \Device\NPF_ prefix before the GUID; the prefix is still
323 allowed for backwards compatibility, but it is not required anymore
324 when specifying the interface
325 * driver_ndis: re-initialize driver interface is the adapter is removed
326 and re-inserted [Bug 159]
327 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
328 big endian hosts [Bug 146]
331 * fixed EAP-GTC response to include correct user identity when run as
332 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
333 * driver_ndis: Fixed encryption mode configuration for unencrypted
334 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
335 refused to associate with open networks) [Bug 106]
336 * driver_ndis: use BSSID OID polling to detect when IBSS network is
337 formed even when ndis_events code is included since some NDIS drivers
338 do not generate media connect events in IBSS mode
339 * config_winreg: allow global ctrl_interface parameter to be configured
341 * config_winreg: added support for saving configuration data into
343 * added support for controlling network device operational state
344 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
345 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
346 that can use this information)
347 * driver_wext: added support for WE-21 change to SSID configuration
348 * driver_wext: fixed privacy configuration for static WEP keys mode
350 * added an optional driver_ops callback for MLME-SETPROTECTION.request
352 * added support for EAP-SAKE (no EAP method number allocated yet, so
353 this is using the same experimental type 255 as EAP-PSK)
354 * added support for dynamically loading EAP methods (.so files) instead
355 of requiring them to be statically linked in; this is disabled by
356 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
360 * do not try to use USIM APDUs when initializing PC/SC for SIM card
361 access for a network that has not enabled EAP-AKA
362 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
363 v0.5.1 due to the new support for expanded EAP types)
364 * added support for generating EAP Expanded Nak
365 * try to fetch scan results once before requesting new scan when
366 starting up in ap_scan=1 mode (this can speed up initial association
367 a lot with, e.g., madwifi-ng driver)
368 * added support for receiving EAPOL frames from a Linux bridge
369 interface (-bbr0 on command line)
370 * fixed EAPOL re-authentication for sessions that used PMKSA caching
371 * changed EAP method registration to use a dynamic list of methods
372 instead of a static list generated at build time
373 * fixed PMKSA cache deinitialization not to use freed memory when
374 removing PMKSA entries
375 * fixed a memory leak in EAP-TTLS re-authentication
376 * reject WPA/WPA2 message 3/4 if it does not include any valid
378 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
379 if the driver does not support SIOCSIWAUTH
382 * driver_test: added better support for multiple APs and STAs by using
383 a directory with sockets that include MAC address for each device in
384 the name (driver_param=test_dir=/tmp/test)
385 * added support for EAP expanded type (vendor specific EAP methods)
386 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
387 option can be changed if needed
388 * wpa_cli/wpa_gui: skip non-socket files in control directory when
389 using UNIX domain sockets; this avoids selecting an incorrect
390 interface (e.g., a PID file could be in this directory, even though
391 use of this directory for something else than socket files is not
393 * fixed TLS library deinitialization after RSN pre-authentication not
394 to disable TLS library for normal authentication
395 * driver_wext: Remove null-termination from SSID length if the driver
396 used it; some Linux drivers do this and they were causing problems in
397 wpa_supplicant not finding matching configuration block. This change
398 would break a case where the SSID actually ends in '\0', but that is
399 not likely to happen in real use.
400 * fixed PMKSA cache processing not to trigger deauthentication if the
401 current PMKSA cache entry is replaced with a valid new entry
402 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
403 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
406 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
407 * added experimental STAKey handshake implementation for IEEE 802.11e
408 direct link setup (DLS); note: this is disabled by default in both
409 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
411 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
412 decrypt AT_ENCR_DATA attributes correctly
413 * fixed EAP-AKA to allow resynchronization within the same session
414 * made code closer to ANSI C89 standard to make it easier to port to
415 other C libraries and compilers
416 * started moving operating system or C library specific functions into
417 wrapper functions defined in os.h and implemented in os_*.c to make
419 * wpa_supplicant can now be built with Microsoft Visual C++
420 (e.g., with the freely available Toolkit 2003 version or Visual
421 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
422 example makefile for nmake
423 * added support for using Windows registry for command line parameters
424 (CONFIG_MAIN=main_winsvc) and configuration data
425 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
426 contents; this version can be run both as a Windows service and as a
427 normal application; 'wpasvc.exe app' to start as applicant,
428 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
429 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
431 * made it possible to link ndis_events.exe functionality into
432 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
433 * added better support for multiple control interface backends
434 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
435 * fixed PC/SC code to use correct length for GSM AUTH command buffer
436 and to not use pioRecvPci with SCardTransmit() calls; these were not
437 causing visible problems with pcsc-lite, but Windows Winscard.dll
438 refused the previously used parameters; this fixes EAP-SIM and
439 EAP-AKA authentication using SIM/USIM card under Windows
440 * added new event loop implementation for Windows using
441 WaitForMultipleObject() instead of select() in order to allow waiting
442 for non-socket objects; this can be selected with
443 CONFIG_ELOOP=eloop_win in .config
444 * added support for selecting l2_packet implementation in .config
445 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
446 winpcap, freebsd, none)
447 * added new l2_packet implementation for WinPcap
448 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
449 reduce latency in EAPOL receive processing from about 100 ms to about
451 * added support for EAP-FAST key derivation using other ciphers than
452 RC4-128-SHA for authentication and AES128-SHA for provisioning
453 * added support for configuring CA certificate as DER file and as a
455 * fixed private key configuration as configuration blob and added
456 support for using PKCS#12 as a blob
457 * tls_gnutls: added support for using PKCS#12 files; added support for
459 * added support for loading trusted CA certificates from Windows
460 certificate store: ca_cert="cert_store://<name>", where <name> is
461 likely CA (Intermediate CA certificates) or ROOT (root certificates)
462 * added C version of ndis_events.cpp and made it possible to build this
463 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
464 easily on cross-compilation builds
465 * added wpasvc.exe into Windows binary release; this is an alternative
466 version of wpa_supplicant.exe with configuration backend using
467 Windows registry and with the entry point designed to run as a
469 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
470 wpasvc.exe and removed this additional tool from the Windows binary
471 release since it is not needed anymore
472 * load winscard.dll functions dynamically when building with MinGW
473 since MinGW does not yet include winscard library
475 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
476 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
477 and WinPcap to receive frames sent to PAE group address
478 * disable EAP state machine when IEEE 802.1X authentication is not used
479 in order to get rid of bogus "EAP failed" messages
480 * fixed OpenSSL error reporting to go through all pending errors to
481 avoid confusing reports of old errors being reported at later point
483 * fixed configuration file updating to not write empty variables
484 (e.g., proto or key_mgmt) that the file parser would not accept
485 * fixed ADD_NETWORK ctrl_iface command to use the same default values
486 for variables as empty network definitions read from config file
488 * fixed EAP state machine to not discard EAP-Failure messages in many
489 cases (e.g., during TLS handshake)
490 * fixed a infinite loop in private key reading if the configured file
491 cannot be parsed successfully
492 * driver_madwifi: added support for madwifi-ng
493 * wpa_gui: do not display password/PSK field contents
494 * wpa_gui: added CA certificate configuration
495 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
496 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
497 the new AP is using different WPA/RSN IE
498 * use longer timeout for IEEE 802.11 association to avoid problems with
499 drivers that may take more than five second to associate
502 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
503 RSN IE, but WPA IE would match with wpa_supplicant configuration
504 * added support for named configuration blobs in order to avoid having
505 to use file system for external files (e.g., certificates);
506 variables can be set to "blob://<blob name>" instead of file path to
507 use a named blob; supported fields: pac_file, client_cert,
509 * fixed RSN pre-authentication (it was broken in the clean up of WPA
510 state machine interface in v0.4.5)
511 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
512 sure the driver configures broadcast decryption correctly
513 * added ca_path (and ca_path2) configuration variables that can be used
514 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
515 system-wide trusted CA list
516 * added support for starting wpa_supplicant without a configuration
517 file (-C argument must be used to set ctrl_interface parameter for
518 this case; in addition, -p argument can be used to provide
519 driver_param; these new arguments can also be used with a
520 configuration to override the values from the configuration)
521 * added global control interface that can be optionally used for adding
522 and removing network interfaces dynamically (-g command line argument
523 for both wpa_supplicant and wpa_cli) without having to restart
524 wpa_supplicant process
526 - try to save configuration whenever something is modified
527 - added WEP key configuration
528 - added possibility to edit the current network configuration
529 * driver_ndis: fixed driver polling not to increase frequency on each
530 received EAPOL frame due to incorrectly cancelled timeout
531 * added simple configuration file examples (in examples subdirectory)
532 * fixed driver_wext.c to filter wireless events based on ifindex to
533 avoid interfaces receiving events from other interfaces
534 * delay sending initial EAPOL-Start couple of seconds to speed up
535 authentication for the most common case of Authenticator starting
536 EAP authentication immediately after association
539 * added a workaround for clearing keys with ndiswrapper to allow
540 roaming from WPA enabled AP to plaintext one
541 * added docbook documentation (doc/docbook) that can be used to
542 generate, e.g., man pages
543 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
544 PF_PACKET in order to prepare for network devices that do not use
545 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
546 * use receipt of EAPOL-Key frame as a lower layer success indication
547 for EAP state machine to allow recovery from dropped EAP-Success
549 * cleaned up internal EAPOL frame processing by not including link
550 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
551 header is added only when transmitted the frame; this makes it easier
552 to use wpa_supplicant on link layers that use different header than
554 * updated EAP-PSK to use draft 9 by default since this can now be
555 tested with hostapd; removed support for draft 3, including
556 server_nai configuration option from network blocks
557 * driver_wired: add PAE address to the multicast address list in order
558 to be able to receive EAPOL frames with drivers that do not include
559 these multicast addresses by default
560 * driver_wext: add support for WE-19
561 * added support for multiple configuration backends (CONFIG_BACKEND
562 option); currently, only 'file' is supported (i.e., the format used
563 in wpa_supplicant.conf)
564 * added support for updating configuration ('wpa_cli save_config');
565 this is disabled by default and can be enabled with global
566 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
567 and wpa_gui to store the configuration changes in a permanent store
568 * added GET_NETWORK ctrl_iface command
569 (e.g., 'wpa_cli get_network 0 ssid')
572 * replaced OpenSSL patch for EAP-FAST support
573 (openssl-tls-extensions.patch) with a more generic and correct
574 patch (the new patch is not compatible with the previous one, so the
575 OpenSSL library will need to be patched with the new patch in order
576 to be able to build wpa_supplicant with EAP-FAST support)
577 * added support for using Windows certificate store (through CryptoAPI)
578 for client certificate and private key operations (EAP-TLS)
579 (see wpa_supplicant.conf for more information on how to configure
580 this with private_key)
581 * ported wpa_gui to Windows
582 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
583 built with the open source version of the Qt4 for Windows
584 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
585 with drivers that do not support WPA
586 * ndis_events: fixed Windows 2000 support
587 * added support for enabling/disabling networks from the list of all
588 configured networks ('wpa_cli enable_network <network id>' and
589 'wpa_cli disable_network <network id>')
590 * added support for adding and removing network from the current
591 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
592 <network id>'); added networks are disabled by default and they can
593 be enabled with enable_network command once the configuration is done
594 for the new network; note: configuration file is not yet updated, so
595 these new networks are lost when wpa_supplicant is restarted
596 * added support for setting network configuration parameters through
597 the control interface, for example:
598 wpa_cli set_network 0 ssid "\"my network\""
599 * fixed parsing of strings that include both " and # within double
600 quoted area (e.g., "start"#end")
601 * added EAP workaround for PEAP session resumption: allow outer,
602 i.e., not tunneled, EAP-Success to terminate session since; this can
603 be disabled with eap_workaround=0
604 (this was allowed for PEAPv1 before, but now it is also allowed for
605 PEAPv0 since at least one RADIUS authentication server seems to be
606 doing this for PEAPv0, too)
607 * wpa_gui: added preliminary support for adding new networks to the
608 wpa_supplicant configuration (double click on the scan results to
609 open network configuration)
612 * removed interface for external EAPOL/EAP supplicant (e.g.,
613 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
614 anymore and is unlikely to be used by anyone
615 * driver_ndis: fixed WinPcap 3.0 support
616 * fixed build with CONFIG_DNET_PCAP=y on Linux
617 * l2_packet: moved different implementations into separate files
621 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
622 (note: ipw2100-1.1.0 is likely to require an update to work with
624 * added support for using ap_scan=2 mode with multiple network blocks;
625 wpa_supplicant will go through the networks one by one until the
626 driver reports a successful association; this uses the same order for
627 networks as scan_ssid=1 scans, i.e., the priority field is ignored
628 and the network block order in the file is used instead
629 * fixed a potential issue in RSN pre-authentication ending up using
630 freed memory if pre-authentication times out
631 * added support for matching alternative subject name extensions of the
632 authentication server certificate; new configuration variables
633 altsubject_match and altsubject_match2
634 * driver_ndis: added support for IEEE 802.1X authentication with wired
636 * added support for querying private key password (EAP-TLS) through the
637 control interface (wpa_cli/wpa_gui) if one is not included in the
639 * driver_broadcom: fixed couple of memory leaks in scan result
641 * EAP-PAX is now registered as EAP type 46
642 * fixed EAP-PAX MAC calculation
643 * fixed EAP-PAX CK and ICK key derivation
644 * added support for using password with EAP-PAX (as an alternative to
645 entering key with eappsk); SHA-1 hash of the password will be used as
647 * added support for arbitrary driver interface parameters through the
648 configuration file with a new driver_param field; this adds a new
649 driver_ops function set_param()
650 * added possibility to override l2_packet module with driver interface
651 API (new send_eapol handler); this can be used to implement driver
652 specific TX/RX functions for EAPOL frames
653 * fixed ctrl_interface_group processing for the case where gid is
654 entered as a number, not group name
655 * driver_test: added support for testing hostapd with wpa_supplicant
656 by using test driver interface without any kernel drivers or network
660 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
661 packets to be encrypted; this was apparently broken by the changed
662 ioctl order in v0.4.0
663 * driver_madwifi: added preliminary support for compiling against 'BSD'
664 branch of madwifi CVS tree
665 * added support for EAP-MSCHAPv2 password retries within the same EAP
666 authentication session
667 * added support for password changes with EAP-MSCHAPv2 (used when the
668 password has expired)
669 * added support for reading additional certificates from PKCS#12 files
670 and adding them to the certificate chain
671 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
673 * fixed a possible double free in EAP-TTLS fast-reauthentication when
674 identity or password is entered through control interface
675 * display EAP Notification messages to user through control interface
676 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
677 * added GUI version of wpa_cli, wpa_gui; this is not build
678 automatically with 'make'; use 'make wpa_gui' to build (this requires
679 Qt development tools)
680 * added 'disconnect' command to control interface for setting
681 wpa_supplicant in state where it will not associate before
682 'reassociate' command has been used
683 * added support for selecting a network from the list of all configured
684 networks ('wpa_cli select_network <network id>'; this disabled all
685 other networks; to re-enable, 'wpa_cli select_network any')
686 * added support for getting scan results through control interface
687 * added EAP workaround for PEAPv1 session resumption: allow outer,
688 i.e., not tunneled, EAP-Success to terminate session since; this can
689 be disabled with eap_workaround=0
691 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
692 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
693 used to reduce the size of the wpa_supplicant considerably if
694 debugging code is not needed
695 * fixed EAPOL-Key validation to drop packets with invalid Key Data
696 Length; such frames could have crashed wpa_supplicant due to buffer
698 * added support for wired authentication (IEEE 802.1X on wired
699 Ethernet); driver interface 'wired'
700 * obsoleted set_wpa() handler in the driver interface API (it can be
701 replaced by moving enable/disable functionality into init()/deinit())
702 (calls to set_wpa() are still present for backwards compatibility,
703 but they may be removed in the future)
704 * driver_madwifi: fixed association in plaintext mode
705 * modified the EAP workaround that accepts EAP-Success with incorrect
706 Identifier to be even less strict about verification in order to
707 interoperate with some authentication servers
708 * added support for sending TLS alerts
709 * added support for 'any' SSID wildcard; if ssid is not configured or
710 is set to an empty string, any SSID will be accepted for non-WPA AP
711 * added support for asking PIN (for SIM) from frontends (e.g.,
712 wpa_cli); if a PIN is needed, but not included in the configuration
713 file, a control interface request is sent and EAP processing is
714 delayed until the PIN is available
715 * added support for using external devices (e.g., a smartcard) for
716 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
717 new wpa_supplicant.conf variables:
718 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
719 - network: engine, engine_id, key_id
720 * added experimental support for EAP-PAX
721 * added monitor mode for wpa_cli (-a<path to a program to run>) that
722 allows external commands (e.g., shell scripts) to be run based on
723 wpa_supplicant events, e.g., when authentication has been completed
724 and data connection is ready; other related wpa_cli arguments:
725 -B (run in background), -P (write PID file); wpa_supplicant has a new
726 command line argument (-W) that can be used to make it wait until a
727 control interface command is received in order to avoid missing
729 * added support for opportunistic WPA2 PMKSA key caching (disabled by
730 default, can be enabled with proactive_key_caching=1)
731 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
732 Authenticator rejects PMKSA caching attempt and the driver is not
733 using assoc_info events
734 * added -P<pid file> argument for wpa_supplicant to write the current
735 process id into a file
737 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
738 * added new phase1 option parameter, include_tls_length=1, to force
739 wpa_supplicant to add TLS Message Length field to all TLS messages
740 even if the packet is not fragmented; this may be needed with some
741 authentication servers
742 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
743 using drivers that take care of AP selection (e.g., when using
745 * fixed reprocessing of pending request after ctrl_iface requests for
746 identity/password/otp
747 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
748 EAP-PEAP and EAP-TTLS
749 * all drivers using driver_wext: set interface up and select Managed
750 mode when starting wpa_supplicant; set interface down when exiting
751 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
752 ipw2100 and ipw2200; please note that this also changed the
753 configuration variable in .config to CONFIG_DRIVER_IPW
756 * fixed a busy loop introduced in v0.3.5 for scan result processing
757 when no matching AP is found
760 * added a workaround for an interoperability issue with a Cisco AP
762 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
763 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
764 retransmission of dropped frames)
765 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
766 (e.g., segfault when processing EAPOL-Key frames)
767 * fixed EAP workaround and fast reauthentication configuration for
768 RSN pre-authentication; previously these were disabled and
769 pre-authentication would fail if the used authentication server
770 requires EAP workarounds
771 * added support for blacklisting APs that fail or timeout
772 authentication in ap_scan=1 mode so that all APs are tried in cases
773 where the ones with strongest signal level are failing authentication
774 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
775 authentication attempt
776 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
777 in the previous authentication (previously, only Phase 1 success was
781 * added preliminary support for IBSS (ad-hoc) mode configuration
782 (mode=1 in network block); this included a new key_mgmt mode
783 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
784 key management; see wpa_supplicant.conf for more details and an
785 example on how to configure this (note: this is currently implemented
786 only for driver_hostapd.c, but the changes should be trivial to add
787 in associate() handler for other drivers, too (assuming the driver
789 * added preliminary port for native Windows (i.e., no cygwin) using
793 * added optional support for GNU Readline and History Libraries for
794 wpa_cli (CONFIG_READLINE)
795 * cleaned up EAP state machine <-> method interface and number of
796 small problems with error case processing not terminating on
797 EAP-Failure but waiting for timeout
798 * added couple of workarounds for interoperability issues with a
799 Cisco AP when using WPA2
800 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
801 Note: This requires a patch for openssl to add support for TLS
802 extensions and number of workarounds for operations without
803 certificates. Proof of concept type of experimental patch is
804 included in openssl-tls-extensions.patch.
807 * fixed private key loading for cases where passphrase is not set
808 * fixed Windows/cygwin L2 packet handler freeing; previous version
809 could cause a segfault when RSN pre-authentication was completed
810 * added support for PMKSA caching with drivers that generate RSN IEs
811 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
812 but similar code can be easily added to driver_ndiswrapper.c once
813 ndiswrapper gets full support for RSN PMKSA caching
814 * improved recovery from PMKID mismatches by requesting full EAP
815 authentication in case of failed PMKSA caching attempt
816 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
817 (this requires that ndis_events is ran while wpa_supplicant is
819 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
820 * added support for driver interfaces to replace the interface name
821 based on driver/OS specific mapping, e.g., in case of driver_ndis,
822 this allows the beginning of the adapter description to be used as
824 * added support for CR+LF (Windows-style) line ends in configuration
826 * driver_ndis: enable radio before starting scanning, disable radio
828 * modified association event handler to set portEnabled = FALSE before
829 clearing port Valid in order to reset EAP state machine and avoid
830 problems with new authentication getting ignored because of state
831 machines ending up in AUTHENTICATED/SUCCESS state based on old
833 * added support for driver events to add PMKID candidates in order to
834 allow drivers to give priority to most likely roaming candidates
835 * driver_hostap: moved PrivacyInvoked configuration to associate()
836 function so that this will not be set for plaintext connections
837 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
838 interface can distinguish plaintext and IEEE 802.1X (no WPA)
840 * fixed static WEP key configuration to use broadcast/default type for
841 all keys (previously, the default TX key was configured as pairwise/
843 * driver_ndis: added legacy WPA capability detection for non-WPA2
845 * added support for setting static WEP keys for IEEE 802.1X without
846 dynamic WEP keying (eapol_flags=0)
849 * added support for reading PKCS#12 (PFX) files (as a replacement for
850 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
851 * fixed compilation with CONFIG_PCSC=y
852 * added new ap_scan mode, ap_scan=2, for drivers that take care of
853 association, but need to be configured with security policy and SSID,
854 e.g., ndiswrapper and NDIS driver; this mode should allow such
855 drivers to work with hidden SSIDs and optimized roaming; when
856 ap_scan=2 is used, only the first network block in the configuration
857 file is used and this configuration should have explicit security
858 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
859 group, proto variables
860 * added experimental port of wpa_supplicant for Windows
861 - driver_ndis.c driver interface (NDIS OIDs)
862 - currently, this requires cygwin and WinPcap
863 - small utility, win_if_list, can be used to get interface name
864 * control interface can now be removed at build time; add
865 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
866 * optional Xsupplicant interface can now be removed at build time;
867 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
868 * added auth_alg to driver interface associate() parameters to make it
869 easier for drivers to configure authentication algorithm as part of
872 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
873 * driver_broadcom: added new driver interface for Broadcom wl.o driver
874 (a generic driver for Broadcom IEEE 802.11a/g cards)
875 * wpa_cli: fixed parsing of -p <path> command line argument
876 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
877 ACK, not tunneled EAP-Success (of which only the first byte was
878 actually send due to a bug in previous code); this seems to
879 interoperate with most RADIUS servers that implements PEAPv1
880 * PEAPv1: added support for terminating PEAP authentication on tunneled
881 EAP-Success message; this can be configured by adding
882 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
883 (some RADIUS servers require this whereas others require a tunneled
885 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
886 the old label for key derivation; previously, the default was 1,
887 but it looks like most existing PEAPv1 implementations use the old
888 label which is thus more suitable default option
889 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
890 * fixed parsing of wep_tx_keyidx
891 * added support for configuring list of allowed Phase 2 EAP types
892 (for both EAP-PEAP and EAP-TTLS) instead of only one type
893 * added support for configuring IEEE 802.11 authentication algorithm
894 (auth_alg; mainly for using Shared Key authentication with static
896 * added support for EAP-AKA (with UMTS SIM)
897 * fixed couple of errors in PCSC handling that could have caused
898 random-looking errors for EAP-SIM
899 * added support for EAP-SIM pseudonyms and fast re-authentication
900 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
902 * added support for EAP-SIM with two challanges
903 (phase1="sim_min_num_chal=3" can be used to require three challenges)
904 * added support for configuring DH/DSA parameters for an ephemeral DH
905 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
906 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
907 and optional DH key exchange to achieve forward secracy with RSA keys
908 * added support for matching subject of the authentication server
909 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
910 configuration variables subject_match and subject_match2
911 * changed SSID configuration in driver_wext.c (used by many driver
912 interfaces) to use ssid_len+1 as the length for SSID since some Linux
914 * fixed couple of unaligned reads in scan result parsing to fix WPA
915 connection on some platforms (e.g., ARM)
916 * added driver interface for Intel ipw2100 driver
917 * added support for LEAP with WPA
918 * added support for larger scan results report (old limit was 4 kB of
919 data, i.e., about 35 or so APs) when using Linux wireless extensions
921 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
922 only if there is a PMKSA cache entry for the current AP
923 * fixed error handling for case where reading of scan results fails:
924 must schedule a new scan or wpa_supplicant will remain waiting
926 * changed debug output to remove shared password/key material by
927 default; all key information can be included with -K command line
928 argument to match the previous behavior
929 * added support for timestamping debug log messages (disabled by
930 default, can be enabled with -t command line argument)
931 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
932 if keys are not configured to be used; this fixes IEEE 802.1X mode
933 with drivers that use this information to configure whether Privacy
934 bit can be in Beacon frames (e.g., ndiswrapper)
935 * avoid clearing driver keys if no keys have been configured since last
936 key clear request; this seems to improve reliability of group key
937 handshake for ndiswrapper & NDIS driver which seems to be suffering
938 of some kind of timing issue when the keys are cleared again after
940 * changed driver interface API:
941 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
942 version is being used (now, this is set to 2; previously, it was
944 - pass pointer to private data structure to all calls
945 - the new API is not backwards compatible; all in-tree driver
946 interfaces has been converted to the new API
947 * added support for controlling multiple interfaces (radios) per
948 wpa_supplicant process; each interface needs to be listed on the
949 command line (-c, -i, -D arguments) with -N as a separator
950 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
951 * added a workaround for EAP servers that incorrectly use same Id for
952 sequential EAP packets
953 * changed libpcap/libdnet configuration to use .config variable,
954 CONFIG_DNET_PCAP, instead of requiring Makefile modification
955 * improved downgrade attack detection in IE verification of msg 3/4:
956 verify both WPA and RSN IEs, if present, not only the selected one;
957 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
958 Probe Response frame, and RSN is enabled in wpa_supplicant
960 * fixed WPA msg 3/4 processing to allow Key Data field contain other
961 IEs than just one WPA IE
962 * added support for FreeBSD and driver interface for the BSD net80211
963 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
964 required kernel mods have not yet been committed
965 * made EAP workarounds configurable; enabled by default, can be
966 disabled with network block option eap_workaround=0
968 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
969 * resolved couple of interoperability issues with EAP-PEAPv1 and
970 Phase 2 (inner EAP) fragment reassembly
971 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
972 AP is using non-zero key index for the unicast key and key index zero
973 for the broadcast key
974 * driver_hostap: fixed IEEE 802.1X WEP key updates and
975 re-authentication by allowing unencrypted EAPOL frames when not using
977 * added a new driver interface, 'wext', which uses only standard,
978 driver independent functionality in Linux wireless extensions;
979 currently, this can be used only for non-WPA IEEE 802.1X mode, but
980 eventually, this is to be extended to support full WPA/WPA2 once
981 Linux wireless extensions get support for this
982 * added support for mode in which the driver is responsible for AP
983 scanning and selection; this is disabled by default and can be
984 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
985 this mode can be used, e.g., with generic 'wext' driver interface to
986 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
987 supporting wireless extensions.
988 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
989 operation with an AP that does not include SSID in the Beacon frames)
990 * added support for new EAP authentication methods:
991 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
992 * added support for asking one-time-passwords from frontends (e.g.,
993 wpa_cli); this 'otp' command works otherwise like 'password' command,
994 but the password is used only once and the frontend will be asked for
995 a new password whenever a request from authenticator requires a
996 password; this can be used with both EAP-OTP and EAP-GTC
997 * changed wpa_cli to automatically re-establish connection so that it
998 does not need to be re-started when wpa_supplicant is terminated and
1000 * improved user data (identity/password/otp) requests through
1001 frontends: process pending EAPOL packets after getting new
1002 information so that full authentication does not need to be
1003 restarted; in addition, send pending requests again whenever a new
1004 frontend is attached
1005 * changed control frontends to use a new directory for socket files to
1006 make it easier for wpa_cli to automatically select between interfaces
1007 and to provide access control for the control interface;
1008 wpa_supplicant.conf: ctrl_interface is now a path
1009 (/var/run/wpa_supplicant is the recommended path) and
1010 ctrl_interface_group can be used to select which group gets access to
1011 the control interface;
1012 wpa_cli: by default, try to connect to the first interface available
1013 in /var/run/wpa_supplicant; this path can be overriden with -p option
1014 and an interface can be selected with -i option (i.e., in most common
1015 cases, wpa_cli does not need to get any arguments)
1016 * added support for LEAP
1017 * added driver interface for Linux ndiswrapper
1018 * added priority option for network blocks in the configuration file;
1019 this allows networks to be grouped based on priority (the scan
1020 results are searched for matches with network blocks in this order)
1023 * sort scan results to improve AP selection
1024 * fixed control interface socket removal for some error cases
1025 * improved scan requesting and authentication timeout
1026 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1028 * PEAP version can now be forced with phase1="peapver=<ver>"
1029 (mostly for testing; by default, the highest version supported by
1030 both the Supplicant and Authentication Server is selected
1032 * added support for madwifi driver (Atheros ar521x)
1033 * added a workaround for cases where AP sets Install Tx/Rx bit for
1034 WPA Group Key messages when pairwise keys are used (without this,
1035 the Group Key would be used for Tx and the AP would drop frames
1037 * added GSM SIM/USIM interface for GSM authentication algorithm for
1038 EAP-SIM; this requires pcsc-lite
1039 * added support for ATMEL AT76C5XXx driver
1040 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1041 does not include key data in the EAPOL-Key frame (i.e., part of
1042 EAP keying material is used as data encryption key)
1043 * added support for using plaintext and static WEP networks
1047 * added support for new EAP authentication methods:
1048 EAP-TTLS/EAP-MD5-Challenge
1050 EAP-TTLS/EAP-MSCHAPv2
1058 EAP-PEAP/MD5-Challenge
1060 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1061 * added support for anonymous identity (to be used when identity is
1062 sent in plaintext; real identity will be used within TLS protected
1063 tunnel (e.g., with EAP-TTLS)
1064 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1065 * added support for requesting identity and password information using
1066 control interface; in other words, the password for EAP-PEAP or
1067 EAP-TTLS does not need to be included in the configuration file since
1068 a frontand (e.g., wpa_cli) can ask it from the user
1069 * improved RSN pre-authentication to use a candidate list and process
1070 all candidates from each scan; not only one per scan
1071 * fixed RSN IE and WPA IE capabilities field parsing
1072 * ignore Tx bit in GTK IE when Pairwise keys are used
1073 * avoid making new scan requests during IEEE 802.1X negotiation
1074 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1075 with TLS support (this replaces the included implementation with
1076 library code to save about 8 kB since the library code is needed
1078 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1079 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1082 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1084 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1085 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1086 - EAP-MD5 (cannot be used with WPA-RADIUS)
1087 [draft-ietf-eap-rfc2284bis-09.txt]
1088 - EAP-TLS [RFC 2716]
1089 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1090 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1091 [draft-kamath-pppext-eap-mschapv2-00.txt]
1092 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1093 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1094 - new configuration file options: eap, identity, password, ca_cert,
1095 client_cert, privatekey, private_key_passwd
1096 - Xsupplicant is not required anymore, but it can be used by
1097 disabling the internal IEEE 802.1X Supplicant with -e command line
1099 - this code is not included in the default build; Makefile need to
1100 be edited for this (uncomment lines for selected functionality)
1101 - EAP-TLS and EAP-PEAP require openssl libraries
1102 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1103 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1104 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1105 EAPOL-Key frames instead of WPA key handshakes)
1106 * added support for IEEE 802.11i/RSN (WPA2)
1107 - improved PTK Key Handshake
1108 - PMKSA caching, pre-authentication
1109 * fixed wpa_supplicant to ignore possible extra data after WPA
1110 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1111 TPTK' error from message 3 of 4-Way Handshake in case the AP
1112 includes extra data after the EAPOL-Key)
1113 * added interface for external programs (frontends) to control
1115 - CLI example (wpa_cli) with interactive mode and command line
1117 - replaced SIGUSR1 status/statistics with the new control interface
1118 * made some feature compile time configurable
1119 - .config file for make
1120 - driver interfaces (hostap, hermes, ..)
1121 - EAPOL/EAP functions
1124 * Initial version of wpa_supplicant
