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)
8 * added a new network configuration option, wpa_ptk_rekey, that can be
9 used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
10 against TKIP deficiencies
11 * added an optional mitigation mechanism for certain attacks against
12 TKIP by delaying Michael MIC error reports by a random amount of time
13 between 0 and 60 seconds; this can be enabled with a build option
14 CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
15 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
17 * updated OpenSSL code for EAP-FAST to use an updated version of the
18 session ticket overriding API that was included into the upstream
19 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
20 needed with that version anymore)
21 * updated userspace MLME instructions to match with the current Linux
22 mac80211 implementation; please also note that this can only be used
23 with driver_nl80211.c (the old code from driver_wext.c was removed)
24 * added support (Linux only) for RoboSwitch chipsets (often found in
25 consumer grade routers); driver interface 'roboswitch'
28 * added support for SHA-256 as X.509 certificate digest when using the
29 internal X.509/TLSv1 implementation
30 * updated management frame protection to use IEEE 802.11w/D6.0
31 * added support for using SHA256-based stronger key derivation for WPA2
33 * fixed FT (IEEE 802.11r) authentication after a failed association to
35 * added support for configuring Phase 2 (inner/tunneled) authentication
36 method with wpa_gui-qt4
39 * added support for EAP Sequences in EAP-FAST Phase 2
40 * added support for using TNC with EAP-FAST
41 * added driver_ps3 for the PS3 Linux wireless driver
42 * added support for optional cryptobinding with PEAPv0
43 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
44 allow fallback to full handshake if server rejects PAC-Opaque
45 * added fragmentation support for EAP-TNC
46 * added support for parsing PKCS #8 formatted private keys into the
47 internal TLS implementation (both PKCS #1 RSA key and PKCS #8
48 encapsulated RSA key can now be used)
49 * added option of using faster, but larger, routines in the internal
50 LibTomMath (for internal TLS implementation) to speed up DH and RSA
51 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
52 * fixed race condition between disassociation event and group key
53 handshake to avoid getting stuck in incorrect state [Bug 261]
54 * fixed opportunistic key caching (proactive_key_caching)
57 * removed 'nai' and 'eappsk' network configuration variables that were
58 previously used for configuring user identity and key for EAP-PSK,
59 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
60 replacement for 'nai' (if old configuration used a separate
61 'identity' value, that would now be configured as
62 'anonymous_identity'). 'password' field is now used as the
63 replacement for 'eappsk' (it can also be set using hexstring to
64 present random binary data)
65 * removed '-w' command line parameter (wait for interface to be added,
66 if needed); cleaner way of handling this functionality is to use an
67 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
68 when an interface is added
69 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
70 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
71 indicating when new scan results become available
72 * added new ctrl_iface command, BSS, to allow scan results to be
73 fetched without hitting the message size limits (this command
74 can be used to iterate through the scan results one BSS at the time)
75 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
76 attributes in EAP-SIM Start/Response when using fast reauthentication
77 * fixed EAPOL not to end up in infinite loop when processing dynamic
78 WEP keys with IEEE 802.1X
79 * fixed problems in getting NDIS events from WMI on Windows 2000
82 * added support for Makefile builds to include debug-log-to-a-file
83 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
84 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
85 lengths properly to avoid potential crash caused by invalid messages
86 * added data structure for storing allocated buffers (struct wpabuf);
87 this does not affect wpa_supplicant usage, but many of the APIs
88 changed and various interfaces (e.g., EAP) is not compatible with old
90 * added support for protecting EAP-AKA/Identity messages with
91 AT_CHECKCODE (optional feature in RFC 4187)
92 * added support for protected result indication with AT_RESULT_IND for
93 EAP-SIM and EAP-AKA (phase1="result_ind=1")
94 * added driver_wext workaround for race condition between scanning and
95 association with drivers that take very long time to scan all
96 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
97 using a longer hardcoded timeout for the scan if the driver supports
98 notifications for scan completion (SIOCGIWSCAN event); this helps,
99 e.g., in cases where wpa_supplicant and madwifi driver ended up in
100 loop where the driver did not even try to associate
101 * stop EAPOL timer tick when no timers are in use in order to reduce
102 power consumption (no need to wake up the process once per second)
104 * added support for privilege separation (run only minimal part of
105 wpa_supplicant functionality as root and rest as unprivileged,
106 non-root process); see 'Privilege separation' in README for details;
107 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
109 * changed scan results data structure to include all information
110 elements to make it easier to support new IEs; old get_scan_result()
111 driver_ops is still supported for backwards compatibility (results
112 are converted internally to the new format), but all drivers should
113 start using the new get_scan_results2() to make them more likely to
114 work with new features
115 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
116 application, i.e., it does not require Qt3Support anymore; Windows
117 binary of wpa_gui.exe is now from this directory and only requires
118 QtCore4.dll and QtGui4.dll libraries
119 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
120 available as a separate package to make wpa_gui installation easier:
121 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
122 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
123 only shared key/password authentication is supported in this version
126 * added support for configuring password as NtPasswordHash
127 (16-byte MD4 hash of password) in hash:<32 hex digits> format
128 * added support for fallback from abbreviated TLS handshake to
129 full handshake when using EAP-FAST (e.g., due to an expired
131 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
132 draft (draft-ietf-emu-eap-gpsk-07.txt)
133 * added support for drivers that take care of RSN 4-way handshake
134 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
135 WPA_ALG_PMK in set_key)
136 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
137 .config); this version supports only ap_scan=2 mode and allow the
138 driver to take care of the 4-way handshake
139 * fixed a buffer overflow in parsing TSF from scan results when using
140 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
142 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
143 * fixed an integer overflow issue in the ASN.1 parser used by the
144 (experimental) internal TLS implementation to avoid a potential
146 * fixed a race condition with -W option (wait for a control interface
147 monitor before starting) that could have caused the first messages to
149 * added support for processing TNCC-TNCS-Messages to report
150 recommendation (allow/none/isolate) when using TNC [Bug 243]
153 * added network configuration parameter 'frequency' for setting
154 initial channel for IBSS (adhoc) networks
155 * added experimental IEEE 802.11r/D6.0 support
156 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
157 * updated EAP-PSK to use the IANA-allocated EAP type 47
158 * fixed EAP-PAX key derivation
159 * fixed EAP-PSK bit ordering of the Flags field
160 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
161 tunnelled identity request (previously, the identifier from the outer
162 method was used, not the tunnelled identifier which could be
164 * added support for fragmentation of outer TLS packets during Phase 2
165 of EAP-PEAP/TTLS/FAST
166 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
167 * added support for EAP-FAST authentication with inner methods that
168 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
169 for PAC provisioning)
170 * added support for authenticated EAP-FAST provisioning
171 * added support for configuring maximum number of EAP-FAST PACs to
172 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
173 * added support for storing EAP-FAST PACs in binary format
174 (fast_pac_format=binary in phase1 string)
175 * fixed dbus ctrl_iface to validate message interface before
176 dispatching to avoid a possible segfault [Bug 190]
177 * fixed PeerKey key derivation to use the correct PRF label
178 * updated Windows binary build to link against OpenSSL 0.9.8d and
179 added support for EAP-FAST
180 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
181 draft (draft-ietf-emu-eap-gpsk-04.txt)
182 * fixed EAP-AKA Notification processing to allow Notification to be
183 processed after AKA Challenge response has been sent
184 * updated to use IEEE 802.11w/D2.0 for management frame protection
186 * fixed EAP-TTLS implementation not to crash on use of freed memory
187 if TLS library initialization fails
188 * added support for EAP-TNC (Trusted Network Connect)
189 (this version implements the EAP-TNC method and EAP-TTLS changes
190 needed to run two methods in sequence (IF-T) and the IF-IMC and
191 IF-TNCCS interfaces from TNCC)
194 * added experimental, integrated TLSv1 client implementation with the
195 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
196 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
197 .config); this can be useful, e.g., if the target system does not
198 have a suitable TLS library and a minimal code size is required
199 (total size of this internal TLS/crypto code is bit under 50 kB on
200 x86 and the crypto code is shared by rest of the supplicant so some
201 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
202 * removed STAKey handshake since PeerKey handshake has replaced it in
203 IEEE 802.11ma and there are no known deployments of STAKey
204 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
205 draft (draft-ietf-emu-eap-gpsk-01.txt)
206 * added preliminary implementation of IEEE 802.11w/D1.0 (management
208 (Note: this requires driver support to work properly.)
209 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
210 * fixed Windows named pipes ctrl_iface to not stop listening for
211 commands if client program opens a named pipe and closes it
212 immediately without sending a command
213 * fixed USIM PIN status determination for the case that PIN is not
214 needed (this allows EAP-AKA to be used with USIM cards that do not
216 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
217 be used with cards that do not support file selection based on
219 * added support for matching the subjectAltName of the authentication
220 server certificate against multiple name components (e.g.,
221 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
222 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
223 affects IEEE 802.1X with dynamic WEP keys)
224 * changed ctrl_iface network configuration 'get' operations to not
225 return password/key material; if these fields are requested, "*"
226 will be returned if the password/key is set, but the value of the
227 parameter is not exposed
230 * added support for building Windows version with UNICODE defined
231 (wide-char functions)
232 * driver_ndis: fixed static WEP configuration to avoid race condition
233 issues with some NDIS drivers between association and setting WEP
235 * driver_ndis: added validation for IELength value in scan results to
236 avoid crashes when using buggy NDIS drivers [Bug 165]
237 * fixed Release|Win32 target in the Visual Studio project files
238 (previously, only Debug|Win32 target was set properly)
239 * changed control interface API call wpa_ctrl_pending() to allow it to
240 return -1 on error (e.g., connection lost); control interface clients
241 will need to make sure that they verify that the value is indeed >0
242 when determining whether there are pending messages
243 * added an alternative control interface backend for Windows targets:
244 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
245 control interface mechanism for Windows builds (previously, UDP to
247 * changed ctrl_interface configuration for UNIX domain sockets:
248 - deprecated ctrl_interface_group variable (it may be removed in
250 - allow both directory and group be configured with ctrl_interface
251 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
252 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
253 case when group is not changed
254 * added support for controlling more than one interface per process in
256 * added a workaround for a case where the AP is using unknown address
257 (e.g., MAC address of the wired interface) as the source address for
258 EAPOL-Key frames; previously, that source address was used as the
259 destination for EAPOL-Key frames and in key derivation; now, BSSID is
260 used even if the source address does not match with it
261 (this resolves an interoperability issue with Thomson SpeedTouch 580)
262 * added a workaround for UDP-based control interface (which was used in
263 Windows builds before this release) to prevent packets with forged
264 addresses from being accepted as local control requests
265 * removed ndis_events.cpp and possibility of using external
266 ndis_events.exe; C version (ndis_events.c) is fully functional and
267 there is no desire to maintain two separate versions of this
269 * ndis_events: Changed NDIS event notification design to use WMI to
270 learn the adapter description through Win32_PnPEntity class; this
271 should fix some cases where the adapter name was not recognized
272 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
274 * fixed selection of the first network in ap_scan=2 mode; previously,
275 wpa_supplicant could get stuck in SCANNING state when only the first
276 network for enabled (e.g., after 'wpa_cli select_network 0')
277 * winsvc: added support for configuring ctrl_interface parameters in
278 registry (ctrl_interface string value in
279 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
280 required to enable control interface (previously, this was hardcoded
282 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
283 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
286 * fixed build with CONFIG_STAKEY=y [Bug 143]
287 * added support for doing MLME (IEEE 802.11 management frame
288 processing) in wpa_supplicant when using Devicescape IEEE 802.11
289 stack (wireless-dev.git tree)
290 * added a new network block configuration option, fragment_size, to
291 configure the maximum EAP fragment size
292 * driver_ndis: Disable WZC automatically for the selected interface to
293 avoid conflicts with two programs trying to control the radio; WZC
294 will be re-enabled (if it was enabled originally) when wpa_supplicant
296 * added an experimental TLSv1 client implementation
297 (CONFIG_TLS=internal) that can be used instead of an external TLS
298 library, e.g., to reduce total size requirement on systems that do
299 not include any TLS library by default (this is not yet complete;
300 basic functionality is there, but certificate validation is not yet
302 * added PeerKey handshake implementation for IEEE 802.11e
303 direct link setup (DLS) to replace STAKey handshake
304 * fixed WPA PSK update through ctrl_iface for the case where the old
305 PSK was derived from an ASCII passphrase and the new PSK is set as
306 a raw PSK (hex string)
307 * added new configuration option for identifying which network block
308 was used (id_str in wpa_supplicant.conf; included on
309 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
310 variable in wpa_cli action scripts; in addition WPA_ID variable is
311 set to the current unique identifier that wpa_supplicant assigned
312 automatically for the network and that can be used with
313 GET_NETWORK/SET_NETWORK ctrl_iface commands)
314 * wpa_cli action script is now called only when the connect/disconnect
315 status changes or when associating with a different network
316 * fixed configuration parser not to remove CCMP from group cipher list
317 if WPA-None (adhoc) is used (pairwise=NONE in that case)
318 * fixed integrated NDIS events processing not to hang the process due
319 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
320 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
321 draft-clancy-emu-eap-shared-secret-00.txt)
322 * added Microsoft Visual Studio 2005 solution and project files for
323 build wpa_supplicant for Windows (see vs2005 subdirectory)
324 * eloop_win: fixed unregistration of Windows events
325 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
326 at the end of RSN pre-authentication and added unregistration of
327 a Windows event to avoid getting eloop_win stuck with an invalid
329 * driver_ndis: added support for selecting AP based on BSSID
330 * added new environmental variable for wpa_cli action scripts:
331 WPA_CTRL_DIR is the current control interface directory
332 * driver_ndis: added support for using NDISUIO instead of WinPcap for
333 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
334 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
335 wpa_supplicant without requiring WinPcap; note that using NDISUIO
336 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
337 only one application to open the device
338 * changed NDIS driver naming to only include device GUID, e.g.,
339 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
340 specific \Device\NPF_ prefix before the GUID; the prefix is still
341 allowed for backwards compatibility, but it is not required anymore
342 when specifying the interface
343 * driver_ndis: re-initialize driver interface is the adapter is removed
344 and re-inserted [Bug 159]
345 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
346 big endian hosts [Bug 146]
349 * fixed EAP-GTC response to include correct user identity when run as
350 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
351 * driver_ndis: Fixed encryption mode configuration for unencrypted
352 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
353 refused to associate with open networks) [Bug 106]
354 * driver_ndis: use BSSID OID polling to detect when IBSS network is
355 formed even when ndis_events code is included since some NDIS drivers
356 do not generate media connect events in IBSS mode
357 * config_winreg: allow global ctrl_interface parameter to be configured
359 * config_winreg: added support for saving configuration data into
361 * added support for controlling network device operational state
362 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
363 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
364 that can use this information)
365 * driver_wext: added support for WE-21 change to SSID configuration
366 * driver_wext: fixed privacy configuration for static WEP keys mode
368 * added an optional driver_ops callback for MLME-SETPROTECTION.request
370 * added support for EAP-SAKE (no EAP method number allocated yet, so
371 this is using the same experimental type 255 as EAP-PSK)
372 * added support for dynamically loading EAP methods (.so files) instead
373 of requiring them to be statically linked in; this is disabled by
374 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
378 * do not try to use USIM APDUs when initializing PC/SC for SIM card
379 access for a network that has not enabled EAP-AKA
380 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
381 v0.5.1 due to the new support for expanded EAP types)
382 * added support for generating EAP Expanded Nak
383 * try to fetch scan results once before requesting new scan when
384 starting up in ap_scan=1 mode (this can speed up initial association
385 a lot with, e.g., madwifi-ng driver)
386 * added support for receiving EAPOL frames from a Linux bridge
387 interface (-bbr0 on command line)
388 * fixed EAPOL re-authentication for sessions that used PMKSA caching
389 * changed EAP method registration to use a dynamic list of methods
390 instead of a static list generated at build time
391 * fixed PMKSA cache deinitialization not to use freed memory when
392 removing PMKSA entries
393 * fixed a memory leak in EAP-TTLS re-authentication
394 * reject WPA/WPA2 message 3/4 if it does not include any valid
396 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
397 if the driver does not support SIOCSIWAUTH
400 * driver_test: added better support for multiple APs and STAs by using
401 a directory with sockets that include MAC address for each device in
402 the name (driver_param=test_dir=/tmp/test)
403 * added support for EAP expanded type (vendor specific EAP methods)
404 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
405 option can be changed if needed
406 * wpa_cli/wpa_gui: skip non-socket files in control directory when
407 using UNIX domain sockets; this avoids selecting an incorrect
408 interface (e.g., a PID file could be in this directory, even though
409 use of this directory for something else than socket files is not
411 * fixed TLS library deinitialization after RSN pre-authentication not
412 to disable TLS library for normal authentication
413 * driver_wext: Remove null-termination from SSID length if the driver
414 used it; some Linux drivers do this and they were causing problems in
415 wpa_supplicant not finding matching configuration block. This change
416 would break a case where the SSID actually ends in '\0', but that is
417 not likely to happen in real use.
418 * fixed PMKSA cache processing not to trigger deauthentication if the
419 current PMKSA cache entry is replaced with a valid new entry
420 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
421 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
424 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
425 * added experimental STAKey handshake implementation for IEEE 802.11e
426 direct link setup (DLS); note: this is disabled by default in both
427 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
429 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
430 decrypt AT_ENCR_DATA attributes correctly
431 * fixed EAP-AKA to allow resynchronization within the same session
432 * made code closer to ANSI C89 standard to make it easier to port to
433 other C libraries and compilers
434 * started moving operating system or C library specific functions into
435 wrapper functions defined in os.h and implemented in os_*.c to make
437 * wpa_supplicant can now be built with Microsoft Visual C++
438 (e.g., with the freely available Toolkit 2003 version or Visual
439 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
440 example makefile for nmake
441 * added support for using Windows registry for command line parameters
442 (CONFIG_MAIN=main_winsvc) and configuration data
443 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
444 contents; this version can be run both as a Windows service and as a
445 normal application; 'wpasvc.exe app' to start as applicant,
446 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
447 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
449 * made it possible to link ndis_events.exe functionality into
450 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
451 * added better support for multiple control interface backends
452 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
453 * fixed PC/SC code to use correct length for GSM AUTH command buffer
454 and to not use pioRecvPci with SCardTransmit() calls; these were not
455 causing visible problems with pcsc-lite, but Windows Winscard.dll
456 refused the previously used parameters; this fixes EAP-SIM and
457 EAP-AKA authentication using SIM/USIM card under Windows
458 * added new event loop implementation for Windows using
459 WaitForMultipleObject() instead of select() in order to allow waiting
460 for non-socket objects; this can be selected with
461 CONFIG_ELOOP=eloop_win in .config
462 * added support for selecting l2_packet implementation in .config
463 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
464 winpcap, freebsd, none)
465 * added new l2_packet implementation for WinPcap
466 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
467 reduce latency in EAPOL receive processing from about 100 ms to about
469 * added support for EAP-FAST key derivation using other ciphers than
470 RC4-128-SHA for authentication and AES128-SHA for provisioning
471 * added support for configuring CA certificate as DER file and as a
473 * fixed private key configuration as configuration blob and added
474 support for using PKCS#12 as a blob
475 * tls_gnutls: added support for using PKCS#12 files; added support for
477 * added support for loading trusted CA certificates from Windows
478 certificate store: ca_cert="cert_store://<name>", where <name> is
479 likely CA (Intermediate CA certificates) or ROOT (root certificates)
480 * added C version of ndis_events.cpp and made it possible to build this
481 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
482 easily on cross-compilation builds
483 * added wpasvc.exe into Windows binary release; this is an alternative
484 version of wpa_supplicant.exe with configuration backend using
485 Windows registry and with the entry point designed to run as a
487 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
488 wpasvc.exe and removed this additional tool from the Windows binary
489 release since it is not needed anymore
490 * load winscard.dll functions dynamically when building with MinGW
491 since MinGW does not yet include winscard library
493 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
494 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
495 and WinPcap to receive frames sent to PAE group address
496 * disable EAP state machine when IEEE 802.1X authentication is not used
497 in order to get rid of bogus "EAP failed" messages
498 * fixed OpenSSL error reporting to go through all pending errors to
499 avoid confusing reports of old errors being reported at later point
501 * fixed configuration file updating to not write empty variables
502 (e.g., proto or key_mgmt) that the file parser would not accept
503 * fixed ADD_NETWORK ctrl_iface command to use the same default values
504 for variables as empty network definitions read from config file
506 * fixed EAP state machine to not discard EAP-Failure messages in many
507 cases (e.g., during TLS handshake)
508 * fixed a infinite loop in private key reading if the configured file
509 cannot be parsed successfully
510 * driver_madwifi: added support for madwifi-ng
511 * wpa_gui: do not display password/PSK field contents
512 * wpa_gui: added CA certificate configuration
513 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
514 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
515 the new AP is using different WPA/RSN IE
516 * use longer timeout for IEEE 802.11 association to avoid problems with
517 drivers that may take more than five second to associate
520 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
521 RSN IE, but WPA IE would match with wpa_supplicant configuration
522 * added support for named configuration blobs in order to avoid having
523 to use file system for external files (e.g., certificates);
524 variables can be set to "blob://<blob name>" instead of file path to
525 use a named blob; supported fields: pac_file, client_cert,
527 * fixed RSN pre-authentication (it was broken in the clean up of WPA
528 state machine interface in v0.4.5)
529 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
530 sure the driver configures broadcast decryption correctly
531 * added ca_path (and ca_path2) configuration variables that can be used
532 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
533 system-wide trusted CA list
534 * added support for starting wpa_supplicant without a configuration
535 file (-C argument must be used to set ctrl_interface parameter for
536 this case; in addition, -p argument can be used to provide
537 driver_param; these new arguments can also be used with a
538 configuration to override the values from the configuration)
539 * added global control interface that can be optionally used for adding
540 and removing network interfaces dynamically (-g command line argument
541 for both wpa_supplicant and wpa_cli) without having to restart
542 wpa_supplicant process
544 - try to save configuration whenever something is modified
545 - added WEP key configuration
546 - added possibility to edit the current network configuration
547 * driver_ndis: fixed driver polling not to increase frequency on each
548 received EAPOL frame due to incorrectly cancelled timeout
549 * added simple configuration file examples (in examples subdirectory)
550 * fixed driver_wext.c to filter wireless events based on ifindex to
551 avoid interfaces receiving events from other interfaces
552 * delay sending initial EAPOL-Start couple of seconds to speed up
553 authentication for the most common case of Authenticator starting
554 EAP authentication immediately after association
557 * added a workaround for clearing keys with ndiswrapper to allow
558 roaming from WPA enabled AP to plaintext one
559 * added docbook documentation (doc/docbook) that can be used to
560 generate, e.g., man pages
561 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
562 PF_PACKET in order to prepare for network devices that do not use
563 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
564 * use receipt of EAPOL-Key frame as a lower layer success indication
565 for EAP state machine to allow recovery from dropped EAP-Success
567 * cleaned up internal EAPOL frame processing by not including link
568 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
569 header is added only when transmitted the frame; this makes it easier
570 to use wpa_supplicant on link layers that use different header than
572 * updated EAP-PSK to use draft 9 by default since this can now be
573 tested with hostapd; removed support for draft 3, including
574 server_nai configuration option from network blocks
575 * driver_wired: add PAE address to the multicast address list in order
576 to be able to receive EAPOL frames with drivers that do not include
577 these multicast addresses by default
578 * driver_wext: add support for WE-19
579 * added support for multiple configuration backends (CONFIG_BACKEND
580 option); currently, only 'file' is supported (i.e., the format used
581 in wpa_supplicant.conf)
582 * added support for updating configuration ('wpa_cli save_config');
583 this is disabled by default and can be enabled with global
584 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
585 and wpa_gui to store the configuration changes in a permanent store
586 * added GET_NETWORK ctrl_iface command
587 (e.g., 'wpa_cli get_network 0 ssid')
590 * replaced OpenSSL patch for EAP-FAST support
591 (openssl-tls-extensions.patch) with a more generic and correct
592 patch (the new patch is not compatible with the previous one, so the
593 OpenSSL library will need to be patched with the new patch in order
594 to be able to build wpa_supplicant with EAP-FAST support)
595 * added support for using Windows certificate store (through CryptoAPI)
596 for client certificate and private key operations (EAP-TLS)
597 (see wpa_supplicant.conf for more information on how to configure
598 this with private_key)
599 * ported wpa_gui to Windows
600 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
601 built with the open source version of the Qt4 for Windows
602 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
603 with drivers that do not support WPA
604 * ndis_events: fixed Windows 2000 support
605 * added support for enabling/disabling networks from the list of all
606 configured networks ('wpa_cli enable_network <network id>' and
607 'wpa_cli disable_network <network id>')
608 * added support for adding and removing network from the current
609 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
610 <network id>'); added networks are disabled by default and they can
611 be enabled with enable_network command once the configuration is done
612 for the new network; note: configuration file is not yet updated, so
613 these new networks are lost when wpa_supplicant is restarted
614 * added support for setting network configuration parameters through
615 the control interface, for example:
616 wpa_cli set_network 0 ssid "\"my network\""
617 * fixed parsing of strings that include both " and # within double
618 quoted area (e.g., "start"#end")
619 * added EAP workaround for PEAP session resumption: allow outer,
620 i.e., not tunneled, EAP-Success to terminate session since; this can
621 be disabled with eap_workaround=0
622 (this was allowed for PEAPv1 before, but now it is also allowed for
623 PEAPv0 since at least one RADIUS authentication server seems to be
624 doing this for PEAPv0, too)
625 * wpa_gui: added preliminary support for adding new networks to the
626 wpa_supplicant configuration (double click on the scan results to
627 open network configuration)
630 * removed interface for external EAPOL/EAP supplicant (e.g.,
631 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
632 anymore and is unlikely to be used by anyone
633 * driver_ndis: fixed WinPcap 3.0 support
634 * fixed build with CONFIG_DNET_PCAP=y on Linux
635 * l2_packet: moved different implementations into separate files
639 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
640 (note: ipw2100-1.1.0 is likely to require an update to work with
642 * added support for using ap_scan=2 mode with multiple network blocks;
643 wpa_supplicant will go through the networks one by one until the
644 driver reports a successful association; this uses the same order for
645 networks as scan_ssid=1 scans, i.e., the priority field is ignored
646 and the network block order in the file is used instead
647 * fixed a potential issue in RSN pre-authentication ending up using
648 freed memory if pre-authentication times out
649 * added support for matching alternative subject name extensions of the
650 authentication server certificate; new configuration variables
651 altsubject_match and altsubject_match2
652 * driver_ndis: added support for IEEE 802.1X authentication with wired
654 * added support for querying private key password (EAP-TLS) through the
655 control interface (wpa_cli/wpa_gui) if one is not included in the
657 * driver_broadcom: fixed couple of memory leaks in scan result
659 * EAP-PAX is now registered as EAP type 46
660 * fixed EAP-PAX MAC calculation
661 * fixed EAP-PAX CK and ICK key derivation
662 * added support for using password with EAP-PAX (as an alternative to
663 entering key with eappsk); SHA-1 hash of the password will be used as
665 * added support for arbitrary driver interface parameters through the
666 configuration file with a new driver_param field; this adds a new
667 driver_ops function set_param()
668 * added possibility to override l2_packet module with driver interface
669 API (new send_eapol handler); this can be used to implement driver
670 specific TX/RX functions for EAPOL frames
671 * fixed ctrl_interface_group processing for the case where gid is
672 entered as a number, not group name
673 * driver_test: added support for testing hostapd with wpa_supplicant
674 by using test driver interface without any kernel drivers or network
678 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
679 packets to be encrypted; this was apparently broken by the changed
680 ioctl order in v0.4.0
681 * driver_madwifi: added preliminary support for compiling against 'BSD'
682 branch of madwifi CVS tree
683 * added support for EAP-MSCHAPv2 password retries within the same EAP
684 authentication session
685 * added support for password changes with EAP-MSCHAPv2 (used when the
686 password has expired)
687 * added support for reading additional certificates from PKCS#12 files
688 and adding them to the certificate chain
689 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
691 * fixed a possible double free in EAP-TTLS fast-reauthentication when
692 identity or password is entered through control interface
693 * display EAP Notification messages to user through control interface
694 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
695 * added GUI version of wpa_cli, wpa_gui; this is not build
696 automatically with 'make'; use 'make wpa_gui' to build (this requires
697 Qt development tools)
698 * added 'disconnect' command to control interface for setting
699 wpa_supplicant in state where it will not associate before
700 'reassociate' command has been used
701 * added support for selecting a network from the list of all configured
702 networks ('wpa_cli select_network <network id>'; this disabled all
703 other networks; to re-enable, 'wpa_cli select_network any')
704 * added support for getting scan results through control interface
705 * added EAP workaround for PEAPv1 session resumption: allow outer,
706 i.e., not tunneled, EAP-Success to terminate session since; this can
707 be disabled with eap_workaround=0
709 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
710 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
711 used to reduce the size of the wpa_supplicant considerably if
712 debugging code is not needed
713 * fixed EAPOL-Key validation to drop packets with invalid Key Data
714 Length; such frames could have crashed wpa_supplicant due to buffer
716 * added support for wired authentication (IEEE 802.1X on wired
717 Ethernet); driver interface 'wired'
718 * obsoleted set_wpa() handler in the driver interface API (it can be
719 replaced by moving enable/disable functionality into init()/deinit())
720 (calls to set_wpa() are still present for backwards compatibility,
721 but they may be removed in the future)
722 * driver_madwifi: fixed association in plaintext mode
723 * modified the EAP workaround that accepts EAP-Success with incorrect
724 Identifier to be even less strict about verification in order to
725 interoperate with some authentication servers
726 * added support for sending TLS alerts
727 * added support for 'any' SSID wildcard; if ssid is not configured or
728 is set to an empty string, any SSID will be accepted for non-WPA AP
729 * added support for asking PIN (for SIM) from frontends (e.g.,
730 wpa_cli); if a PIN is needed, but not included in the configuration
731 file, a control interface request is sent and EAP processing is
732 delayed until the PIN is available
733 * added support for using external devices (e.g., a smartcard) for
734 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
735 new wpa_supplicant.conf variables:
736 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
737 - network: engine, engine_id, key_id
738 * added experimental support for EAP-PAX
739 * added monitor mode for wpa_cli (-a<path to a program to run>) that
740 allows external commands (e.g., shell scripts) to be run based on
741 wpa_supplicant events, e.g., when authentication has been completed
742 and data connection is ready; other related wpa_cli arguments:
743 -B (run in background), -P (write PID file); wpa_supplicant has a new
744 command line argument (-W) that can be used to make it wait until a
745 control interface command is received in order to avoid missing
747 * added support for opportunistic WPA2 PMKSA key caching (disabled by
748 default, can be enabled with proactive_key_caching=1)
749 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
750 Authenticator rejects PMKSA caching attempt and the driver is not
751 using assoc_info events
752 * added -P<pid file> argument for wpa_supplicant to write the current
753 process id into a file
755 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
756 * added new phase1 option parameter, include_tls_length=1, to force
757 wpa_supplicant to add TLS Message Length field to all TLS messages
758 even if the packet is not fragmented; this may be needed with some
759 authentication servers
760 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
761 using drivers that take care of AP selection (e.g., when using
763 * fixed reprocessing of pending request after ctrl_iface requests for
764 identity/password/otp
765 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
766 EAP-PEAP and EAP-TTLS
767 * all drivers using driver_wext: set interface up and select Managed
768 mode when starting wpa_supplicant; set interface down when exiting
769 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
770 ipw2100 and ipw2200; please note that this also changed the
771 configuration variable in .config to CONFIG_DRIVER_IPW
774 * fixed a busy loop introduced in v0.3.5 for scan result processing
775 when no matching AP is found
778 * added a workaround for an interoperability issue with a Cisco AP
780 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
781 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
782 retransmission of dropped frames)
783 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
784 (e.g., segfault when processing EAPOL-Key frames)
785 * fixed EAP workaround and fast reauthentication configuration for
786 RSN pre-authentication; previously these were disabled and
787 pre-authentication would fail if the used authentication server
788 requires EAP workarounds
789 * added support for blacklisting APs that fail or timeout
790 authentication in ap_scan=1 mode so that all APs are tried in cases
791 where the ones with strongest signal level are failing authentication
792 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
793 authentication attempt
794 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
795 in the previous authentication (previously, only Phase 1 success was
799 * added preliminary support for IBSS (ad-hoc) mode configuration
800 (mode=1 in network block); this included a new key_mgmt mode
801 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
802 key management; see wpa_supplicant.conf for more details and an
803 example on how to configure this (note: this is currently implemented
804 only for driver_hostapd.c, but the changes should be trivial to add
805 in associate() handler for other drivers, too (assuming the driver
807 * added preliminary port for native Windows (i.e., no cygwin) using
811 * added optional support for GNU Readline and History Libraries for
812 wpa_cli (CONFIG_READLINE)
813 * cleaned up EAP state machine <-> method interface and number of
814 small problems with error case processing not terminating on
815 EAP-Failure but waiting for timeout
816 * added couple of workarounds for interoperability issues with a
817 Cisco AP when using WPA2
818 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
819 Note: This requires a patch for openssl to add support for TLS
820 extensions and number of workarounds for operations without
821 certificates. Proof of concept type of experimental patch is
822 included in openssl-tls-extensions.patch.
825 * fixed private key loading for cases where passphrase is not set
826 * fixed Windows/cygwin L2 packet handler freeing; previous version
827 could cause a segfault when RSN pre-authentication was completed
828 * added support for PMKSA caching with drivers that generate RSN IEs
829 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
830 but similar code can be easily added to driver_ndiswrapper.c once
831 ndiswrapper gets full support for RSN PMKSA caching
832 * improved recovery from PMKID mismatches by requesting full EAP
833 authentication in case of failed PMKSA caching attempt
834 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
835 (this requires that ndis_events is ran while wpa_supplicant is
837 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
838 * added support for driver interfaces to replace the interface name
839 based on driver/OS specific mapping, e.g., in case of driver_ndis,
840 this allows the beginning of the adapter description to be used as
842 * added support for CR+LF (Windows-style) line ends in configuration
844 * driver_ndis: enable radio before starting scanning, disable radio
846 * modified association event handler to set portEnabled = FALSE before
847 clearing port Valid in order to reset EAP state machine and avoid
848 problems with new authentication getting ignored because of state
849 machines ending up in AUTHENTICATED/SUCCESS state based on old
851 * added support for driver events to add PMKID candidates in order to
852 allow drivers to give priority to most likely roaming candidates
853 * driver_hostap: moved PrivacyInvoked configuration to associate()
854 function so that this will not be set for plaintext connections
855 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
856 interface can distinguish plaintext and IEEE 802.1X (no WPA)
858 * fixed static WEP key configuration to use broadcast/default type for
859 all keys (previously, the default TX key was configured as pairwise/
861 * driver_ndis: added legacy WPA capability detection for non-WPA2
863 * added support for setting static WEP keys for IEEE 802.1X without
864 dynamic WEP keying (eapol_flags=0)
867 * added support for reading PKCS#12 (PFX) files (as a replacement for
868 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
869 * fixed compilation with CONFIG_PCSC=y
870 * added new ap_scan mode, ap_scan=2, for drivers that take care of
871 association, but need to be configured with security policy and SSID,
872 e.g., ndiswrapper and NDIS driver; this mode should allow such
873 drivers to work with hidden SSIDs and optimized roaming; when
874 ap_scan=2 is used, only the first network block in the configuration
875 file is used and this configuration should have explicit security
876 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
877 group, proto variables
878 * added experimental port of wpa_supplicant for Windows
879 - driver_ndis.c driver interface (NDIS OIDs)
880 - currently, this requires cygwin and WinPcap
881 - small utility, win_if_list, can be used to get interface name
882 * control interface can now be removed at build time; add
883 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
884 * optional Xsupplicant interface can now be removed at build time;
885 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
886 * added auth_alg to driver interface associate() parameters to make it
887 easier for drivers to configure authentication algorithm as part of
890 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
891 * driver_broadcom: added new driver interface for Broadcom wl.o driver
892 (a generic driver for Broadcom IEEE 802.11a/g cards)
893 * wpa_cli: fixed parsing of -p <path> command line argument
894 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
895 ACK, not tunneled EAP-Success (of which only the first byte was
896 actually send due to a bug in previous code); this seems to
897 interoperate with most RADIUS servers that implements PEAPv1
898 * PEAPv1: added support for terminating PEAP authentication on tunneled
899 EAP-Success message; this can be configured by adding
900 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
901 (some RADIUS servers require this whereas others require a tunneled
903 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
904 the old label for key derivation; previously, the default was 1,
905 but it looks like most existing PEAPv1 implementations use the old
906 label which is thus more suitable default option
907 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
908 * fixed parsing of wep_tx_keyidx
909 * added support for configuring list of allowed Phase 2 EAP types
910 (for both EAP-PEAP and EAP-TTLS) instead of only one type
911 * added support for configuring IEEE 802.11 authentication algorithm
912 (auth_alg; mainly for using Shared Key authentication with static
914 * added support for EAP-AKA (with UMTS SIM)
915 * fixed couple of errors in PCSC handling that could have caused
916 random-looking errors for EAP-SIM
917 * added support for EAP-SIM pseudonyms and fast re-authentication
918 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
920 * added support for EAP-SIM with two challanges
921 (phase1="sim_min_num_chal=3" can be used to require three challenges)
922 * added support for configuring DH/DSA parameters for an ephemeral DH
923 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
924 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
925 and optional DH key exchange to achieve forward secracy with RSA keys
926 * added support for matching subject of the authentication server
927 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
928 configuration variables subject_match and subject_match2
929 * changed SSID configuration in driver_wext.c (used by many driver
930 interfaces) to use ssid_len+1 as the length for SSID since some Linux
932 * fixed couple of unaligned reads in scan result parsing to fix WPA
933 connection on some platforms (e.g., ARM)
934 * added driver interface for Intel ipw2100 driver
935 * added support for LEAP with WPA
936 * added support for larger scan results report (old limit was 4 kB of
937 data, i.e., about 35 or so APs) when using Linux wireless extensions
939 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
940 only if there is a PMKSA cache entry for the current AP
941 * fixed error handling for case where reading of scan results fails:
942 must schedule a new scan or wpa_supplicant will remain waiting
944 * changed debug output to remove shared password/key material by
945 default; all key information can be included with -K command line
946 argument to match the previous behavior
947 * added support for timestamping debug log messages (disabled by
948 default, can be enabled with -t command line argument)
949 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
950 if keys are not configured to be used; this fixes IEEE 802.1X mode
951 with drivers that use this information to configure whether Privacy
952 bit can be in Beacon frames (e.g., ndiswrapper)
953 * avoid clearing driver keys if no keys have been configured since last
954 key clear request; this seems to improve reliability of group key
955 handshake for ndiswrapper & NDIS driver which seems to be suffering
956 of some kind of timing issue when the keys are cleared again after
958 * changed driver interface API:
959 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
960 version is being used (now, this is set to 2; previously, it was
962 - pass pointer to private data structure to all calls
963 - the new API is not backwards compatible; all in-tree driver
964 interfaces has been converted to the new API
965 * added support for controlling multiple interfaces (radios) per
966 wpa_supplicant process; each interface needs to be listed on the
967 command line (-c, -i, -D arguments) with -N as a separator
968 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
969 * added a workaround for EAP servers that incorrectly use same Id for
970 sequential EAP packets
971 * changed libpcap/libdnet configuration to use .config variable,
972 CONFIG_DNET_PCAP, instead of requiring Makefile modification
973 * improved downgrade attack detection in IE verification of msg 3/4:
974 verify both WPA and RSN IEs, if present, not only the selected one;
975 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
976 Probe Response frame, and RSN is enabled in wpa_supplicant
978 * fixed WPA msg 3/4 processing to allow Key Data field contain other
979 IEs than just one WPA IE
980 * added support for FreeBSD and driver interface for the BSD net80211
981 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
982 required kernel mods have not yet been committed
983 * made EAP workarounds configurable; enabled by default, can be
984 disabled with network block option eap_workaround=0
986 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
987 * resolved couple of interoperability issues with EAP-PEAPv1 and
988 Phase 2 (inner EAP) fragment reassembly
989 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
990 AP is using non-zero key index for the unicast key and key index zero
991 for the broadcast key
992 * driver_hostap: fixed IEEE 802.1X WEP key updates and
993 re-authentication by allowing unencrypted EAPOL frames when not using
995 * added a new driver interface, 'wext', which uses only standard,
996 driver independent functionality in Linux wireless extensions;
997 currently, this can be used only for non-WPA IEEE 802.1X mode, but
998 eventually, this is to be extended to support full WPA/WPA2 once
999 Linux wireless extensions get support for this
1000 * added support for mode in which the driver is responsible for AP
1001 scanning and selection; this is disabled by default and can be
1002 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
1003 this mode can be used, e.g., with generic 'wext' driver interface to
1004 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
1005 supporting wireless extensions.
1006 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
1007 operation with an AP that does not include SSID in the Beacon frames)
1008 * added support for new EAP authentication methods:
1009 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
1010 * added support for asking one-time-passwords from frontends (e.g.,
1011 wpa_cli); this 'otp' command works otherwise like 'password' command,
1012 but the password is used only once and the frontend will be asked for
1013 a new password whenever a request from authenticator requires a
1014 password; this can be used with both EAP-OTP and EAP-GTC
1015 * changed wpa_cli to automatically re-establish connection so that it
1016 does not need to be re-started when wpa_supplicant is terminated and
1018 * improved user data (identity/password/otp) requests through
1019 frontends: process pending EAPOL packets after getting new
1020 information so that full authentication does not need to be
1021 restarted; in addition, send pending requests again whenever a new
1022 frontend is attached
1023 * changed control frontends to use a new directory for socket files to
1024 make it easier for wpa_cli to automatically select between interfaces
1025 and to provide access control for the control interface;
1026 wpa_supplicant.conf: ctrl_interface is now a path
1027 (/var/run/wpa_supplicant is the recommended path) and
1028 ctrl_interface_group can be used to select which group gets access to
1029 the control interface;
1030 wpa_cli: by default, try to connect to the first interface available
1031 in /var/run/wpa_supplicant; this path can be overriden with -p option
1032 and an interface can be selected with -i option (i.e., in most common
1033 cases, wpa_cli does not need to get any arguments)
1034 * added support for LEAP
1035 * added driver interface for Linux ndiswrapper
1036 * added priority option for network blocks in the configuration file;
1037 this allows networks to be grouped based on priority (the scan
1038 results are searched for matches with network blocks in this order)
1041 * sort scan results to improve AP selection
1042 * fixed control interface socket removal for some error cases
1043 * improved scan requesting and authentication timeout
1044 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1046 * PEAP version can now be forced with phase1="peapver=<ver>"
1047 (mostly for testing; by default, the highest version supported by
1048 both the Supplicant and Authentication Server is selected
1050 * added support for madwifi driver (Atheros ar521x)
1051 * added a workaround for cases where AP sets Install Tx/Rx bit for
1052 WPA Group Key messages when pairwise keys are used (without this,
1053 the Group Key would be used for Tx and the AP would drop frames
1055 * added GSM SIM/USIM interface for GSM authentication algorithm for
1056 EAP-SIM; this requires pcsc-lite
1057 * added support for ATMEL AT76C5XXx driver
1058 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1059 does not include key data in the EAPOL-Key frame (i.e., part of
1060 EAP keying material is used as data encryption key)
1061 * added support for using plaintext and static WEP networks
1065 * added support for new EAP authentication methods:
1066 EAP-TTLS/EAP-MD5-Challenge
1068 EAP-TTLS/EAP-MSCHAPv2
1076 EAP-PEAP/MD5-Challenge
1078 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1079 * added support for anonymous identity (to be used when identity is
1080 sent in plaintext; real identity will be used within TLS protected
1081 tunnel (e.g., with EAP-TTLS)
1082 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1083 * added support for requesting identity and password information using
1084 control interface; in other words, the password for EAP-PEAP or
1085 EAP-TTLS does not need to be included in the configuration file since
1086 a frontand (e.g., wpa_cli) can ask it from the user
1087 * improved RSN pre-authentication to use a candidate list and process
1088 all candidates from each scan; not only one per scan
1089 * fixed RSN IE and WPA IE capabilities field parsing
1090 * ignore Tx bit in GTK IE when Pairwise keys are used
1091 * avoid making new scan requests during IEEE 802.1X negotiation
1092 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1093 with TLS support (this replaces the included implementation with
1094 library code to save about 8 kB since the library code is needed
1096 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1097 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1100 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1102 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1103 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1104 - EAP-MD5 (cannot be used with WPA-RADIUS)
1105 [draft-ietf-eap-rfc2284bis-09.txt]
1106 - EAP-TLS [RFC 2716]
1107 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1108 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1109 [draft-kamath-pppext-eap-mschapv2-00.txt]
1110 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1111 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1112 - new configuration file options: eap, identity, password, ca_cert,
1113 client_cert, privatekey, private_key_passwd
1114 - Xsupplicant is not required anymore, but it can be used by
1115 disabling the internal IEEE 802.1X Supplicant with -e command line
1117 - this code is not included in the default build; Makefile need to
1118 be edited for this (uncomment lines for selected functionality)
1119 - EAP-TLS and EAP-PEAP require openssl libraries
1120 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1121 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1122 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1123 EAPOL-Key frames instead of WPA key handshakes)
1124 * added support for IEEE 802.11i/RSN (WPA2)
1125 - improved PTK Key Handshake
1126 - PMKSA caching, pre-authentication
1127 * fixed wpa_supplicant to ignore possible extra data after WPA
1128 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1129 TPTK' error from message 3 of 4-Way Handshake in case the AP
1130 includes extra data after the EAPOL-Key)
1131 * added interface for external programs (frontends) to control
1133 - CLI example (wpa_cli) with interactive mode and command line
1135 - replaced SIGUSR1 status/statistics with the new control interface
1136 * made some feature compile time configurable
1137 - .config file for make
1138 - driver interfaces (hostap, hermes, ..)
1139 - EAPOL/EAP functions
1142 * Initial version of wpa_supplicant
