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
13 * added support for SHA-256 as X.509 certificate digest when using the
14 internal X.509/TLSv1 implementation
15 * updated management frame protection to use IEEE 802.11w/D6.0
16 * added support for using SHA256-based stronger key derivation for WPA2
18 * fixed FT (IEEE 802.11r) authentication after a failed association to
20 * added support for configuring Phase 2 (inner/tunneled) authentication
21 method with wpa_gui-qt4
24 * added support for EAP Sequences in EAP-FAST Phase 2
25 * added support for using TNC with EAP-FAST
26 * added driver_ps3 for the PS3 Linux wireless driver
27 * added support for optional cryptobinding with PEAPv0
28 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
29 allow fallback to full handshake if server rejects PAC-Opaque
30 * added fragmentation support for EAP-TNC
31 * added support for parsing PKCS #8 formatted private keys into the
32 internal TLS implementation (both PKCS #1 RSA key and PKCS #8
33 encapsulated RSA key can now be used)
34 * added option of using faster, but larger, routines in the internal
35 LibTomMath (for internal TLS implementation) to speed up DH and RSA
36 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
37 * fixed race condition between disassociation event and group key
38 handshake to avoid getting stuck in incorrect state [Bug 261]
39 * fixed opportunistic key caching (proactive_key_caching)
42 * removed 'nai' and 'eappsk' network configuration variables that were
43 previously used for configuring user identity and key for EAP-PSK,
44 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
45 replacement for 'nai' (if old configuration used a separate
46 'identity' value, that would now be configured as
47 'anonymous_identity'). 'password' field is now used as the
48 replacement for 'eappsk' (it can also be set using hexstring to
49 present random binary data)
50 * removed '-w' command line parameter (wait for interface to be added,
51 if needed); cleaner way of handling this functionality is to use an
52 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
53 when an interface is added
54 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
55 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
56 indicating when new scan results become available
57 * added new ctrl_iface command, BSS, to allow scan results to be
58 fetched without hitting the message size limits (this command
59 can be used to iterate through the scan results one BSS at the time)
60 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
61 attributes in EAP-SIM Start/Response when using fast reauthentication
62 * fixed EAPOL not to end up in infinite loop when processing dynamic
63 WEP keys with IEEE 802.1X
64 * fixed problems in getting NDIS events from WMI on Windows 2000
67 * added support for Makefile builds to include debug-log-to-a-file
68 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
69 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
70 lengths properly to avoid potential crash caused by invalid messages
71 * added data structure for storing allocated buffers (struct wpabuf);
72 this does not affect wpa_supplicant usage, but many of the APIs
73 changed and various interfaces (e.g., EAP) is not compatible with old
75 * added support for protecting EAP-AKA/Identity messages with
76 AT_CHECKCODE (optional feature in RFC 4187)
77 * added support for protected result indication with AT_RESULT_IND for
78 EAP-SIM and EAP-AKA (phase1="result_ind=1")
79 * added driver_wext workaround for race condition between scanning and
80 association with drivers that take very long time to scan all
81 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
82 using a longer hardcoded timeout for the scan if the driver supports
83 notifications for scan completion (SIOCGIWSCAN event); this helps,
84 e.g., in cases where wpa_supplicant and madwifi driver ended up in
85 loop where the driver did not even try to associate
86 * stop EAPOL timer tick when no timers are in use in order to reduce
87 power consumption (no need to wake up the process once per second)
89 * added support for privilege separation (run only minimal part of
90 wpa_supplicant functionality as root and rest as unprivileged,
91 non-root process); see 'Privilege separation' in README for details;
92 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
94 * changed scan results data structure to include all information
95 elements to make it easier to support new IEs; old get_scan_result()
96 driver_ops is still supported for backwards compatibility (results
97 are converted internally to the new format), but all drivers should
98 start using the new get_scan_results2() to make them more likely to
99 work with new features
100 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
101 application, i.e., it does not require Qt3Support anymore; Windows
102 binary of wpa_gui.exe is now from this directory and only requires
103 QtCore4.dll and QtGui4.dll libraries
104 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
105 available as a separate package to make wpa_gui installation easier:
106 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
107 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
108 only shared key/password authentication is supported in this version
111 * added support for configuring password as NtPasswordHash
112 (16-byte MD4 hash of password) in hash:<32 hex digits> format
113 * added support for fallback from abbreviated TLS handshake to
114 full handshake when using EAP-FAST (e.g., due to an expired
116 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
117 draft (draft-ietf-emu-eap-gpsk-07.txt)
118 * added support for drivers that take care of RSN 4-way handshake
119 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
120 WPA_ALG_PMK in set_key)
121 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
122 .config); this version supports only ap_scan=2 mode and allow the
123 driver to take care of the 4-way handshake
124 * fixed a buffer overflow in parsing TSF from scan results when using
125 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
127 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
128 * fixed an integer overflow issue in the ASN.1 parser used by the
129 (experimental) internal TLS implementation to avoid a potential
131 * fixed a race condition with -W option (wait for a control interface
132 monitor before starting) that could have caused the first messages to
134 * added support for processing TNCC-TNCS-Messages to report
135 recommendation (allow/none/isolate) when using TNC [Bug 243]
138 * added network configuration parameter 'frequency' for setting
139 initial channel for IBSS (adhoc) networks
140 * added experimental IEEE 802.11r/D6.0 support
141 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
142 * updated EAP-PSK to use the IANA-allocated EAP type 47
143 * fixed EAP-PAX key derivation
144 * fixed EAP-PSK bit ordering of the Flags field
145 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
146 tunnelled identity request (previously, the identifier from the outer
147 method was used, not the tunnelled identifier which could be
149 * added support for fragmentation of outer TLS packets during Phase 2
150 of EAP-PEAP/TTLS/FAST
151 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
152 * added support for EAP-FAST authentication with inner methods that
153 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
154 for PAC provisioning)
155 * added support for authenticated EAP-FAST provisioning
156 * added support for configuring maximum number of EAP-FAST PACs to
157 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
158 * added support for storing EAP-FAST PACs in binary format
159 (fast_pac_format=binary in phase1 string)
160 * fixed dbus ctrl_iface to validate message interface before
161 dispatching to avoid a possible segfault [Bug 190]
162 * fixed PeerKey key derivation to use the correct PRF label
163 * updated Windows binary build to link against OpenSSL 0.9.8d and
164 added support for EAP-FAST
165 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
166 draft (draft-ietf-emu-eap-gpsk-04.txt)
167 * fixed EAP-AKA Notification processing to allow Notification to be
168 processed after AKA Challenge response has been sent
169 * updated to use IEEE 802.11w/D2.0 for management frame protection
171 * fixed EAP-TTLS implementation not to crash on use of freed memory
172 if TLS library initialization fails
173 * added support for EAP-TNC (Trusted Network Connect)
174 (this version implements the EAP-TNC method and EAP-TTLS changes
175 needed to run two methods in sequence (IF-T) and the IF-IMC and
176 IF-TNCCS interfaces from TNCC)
179 * added experimental, integrated TLSv1 client implementation with the
180 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
181 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
182 .config); this can be useful, e.g., if the target system does not
183 have a suitable TLS library and a minimal code size is required
184 (total size of this internal TLS/crypto code is bit under 50 kB on
185 x86 and the crypto code is shared by rest of the supplicant so some
186 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
187 * removed STAKey handshake since PeerKey handshake has replaced it in
188 IEEE 802.11ma and there are no known deployments of STAKey
189 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
190 draft (draft-ietf-emu-eap-gpsk-01.txt)
191 * added preliminary implementation of IEEE 802.11w/D1.0 (management
193 (Note: this requires driver support to work properly.)
194 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
195 * fixed Windows named pipes ctrl_iface to not stop listening for
196 commands if client program opens a named pipe and closes it
197 immediately without sending a command
198 * fixed USIM PIN status determination for the case that PIN is not
199 needed (this allows EAP-AKA to be used with USIM cards that do not
201 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
202 be used with cards that do not support file selection based on
204 * added support for matching the subjectAltName of the authentication
205 server certificate against multiple name components (e.g.,
206 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
207 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
208 affects IEEE 802.1X with dynamic WEP keys)
209 * changed ctrl_iface network configuration 'get' operations to not
210 return password/key material; if these fields are requested, "*"
211 will be returned if the password/key is set, but the value of the
212 parameter is not exposed
215 * added support for building Windows version with UNICODE defined
216 (wide-char functions)
217 * driver_ndis: fixed static WEP configuration to avoid race condition
218 issues with some NDIS drivers between association and setting WEP
220 * driver_ndis: added validation for IELength value in scan results to
221 avoid crashes when using buggy NDIS drivers [Bug 165]
222 * fixed Release|Win32 target in the Visual Studio project files
223 (previously, only Debug|Win32 target was set properly)
224 * changed control interface API call wpa_ctrl_pending() to allow it to
225 return -1 on error (e.g., connection lost); control interface clients
226 will need to make sure that they verify that the value is indeed >0
227 when determining whether there are pending messages
228 * added an alternative control interface backend for Windows targets:
229 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
230 control interface mechanism for Windows builds (previously, UDP to
232 * changed ctrl_interface configuration for UNIX domain sockets:
233 - deprecated ctrl_interface_group variable (it may be removed in
235 - allow both directory and group be configured with ctrl_interface
236 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
237 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
238 case when group is not changed
239 * added support for controlling more than one interface per process in
241 * added a workaround for a case where the AP is using unknown address
242 (e.g., MAC address of the wired interface) as the source address for
243 EAPOL-Key frames; previously, that source address was used as the
244 destination for EAPOL-Key frames and in key derivation; now, BSSID is
245 used even if the source address does not match with it
246 (this resolves an interoperability issue with Thomson SpeedTouch 580)
247 * added a workaround for UDP-based control interface (which was used in
248 Windows builds before this release) to prevent packets with forged
249 addresses from being accepted as local control requests
250 * removed ndis_events.cpp and possibility of using external
251 ndis_events.exe; C version (ndis_events.c) is fully functional and
252 there is no desire to maintain two separate versions of this
254 * ndis_events: Changed NDIS event notification design to use WMI to
255 learn the adapter description through Win32_PnPEntity class; this
256 should fix some cases where the adapter name was not recognized
257 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
259 * fixed selection of the first network in ap_scan=2 mode; previously,
260 wpa_supplicant could get stuck in SCANNING state when only the first
261 network for enabled (e.g., after 'wpa_cli select_network 0')
262 * winsvc: added support for configuring ctrl_interface parameters in
263 registry (ctrl_interface string value in
264 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
265 required to enable control interface (previously, this was hardcoded
267 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
268 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
271 * fixed build with CONFIG_STAKEY=y [Bug 143]
272 * added support for doing MLME (IEEE 802.11 management frame
273 processing) in wpa_supplicant when using Devicescape IEEE 802.11
274 stack (wireless-dev.git tree)
275 * added a new network block configuration option, fragment_size, to
276 configure the maximum EAP fragment size
277 * driver_ndis: Disable WZC automatically for the selected interface to
278 avoid conflicts with two programs trying to control the radio; WZC
279 will be re-enabled (if it was enabled originally) when wpa_supplicant
281 * added an experimental TLSv1 client implementation
282 (CONFIG_TLS=internal) that can be used instead of an external TLS
283 library, e.g., to reduce total size requirement on systems that do
284 not include any TLS library by default (this is not yet complete;
285 basic functionality is there, but certificate validation is not yet
287 * added PeerKey handshake implementation for IEEE 802.11e
288 direct link setup (DLS) to replace STAKey handshake
289 * fixed WPA PSK update through ctrl_iface for the case where the old
290 PSK was derived from an ASCII passphrase and the new PSK is set as
291 a raw PSK (hex string)
292 * added new configuration option for identifying which network block
293 was used (id_str in wpa_supplicant.conf; included on
294 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
295 variable in wpa_cli action scripts; in addition WPA_ID variable is
296 set to the current unique identifier that wpa_supplicant assigned
297 automatically for the network and that can be used with
298 GET_NETWORK/SET_NETWORK ctrl_iface commands)
299 * wpa_cli action script is now called only when the connect/disconnect
300 status changes or when associating with a different network
301 * fixed configuration parser not to remove CCMP from group cipher list
302 if WPA-None (adhoc) is used (pairwise=NONE in that case)
303 * fixed integrated NDIS events processing not to hang the process due
304 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
305 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
306 draft-clancy-emu-eap-shared-secret-00.txt)
307 * added Microsoft Visual Studio 2005 solution and project files for
308 build wpa_supplicant for Windows (see vs2005 subdirectory)
309 * eloop_win: fixed unregistration of Windows events
310 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
311 at the end of RSN pre-authentication and added unregistration of
312 a Windows event to avoid getting eloop_win stuck with an invalid
314 * driver_ndis: added support for selecting AP based on BSSID
315 * added new environmental variable for wpa_cli action scripts:
316 WPA_CTRL_DIR is the current control interface directory
317 * driver_ndis: added support for using NDISUIO instead of WinPcap for
318 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
319 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
320 wpa_supplicant without requiring WinPcap; note that using NDISUIO
321 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
322 only one application to open the device
323 * changed NDIS driver naming to only include device GUID, e.g.,
324 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
325 specific \Device\NPF_ prefix before the GUID; the prefix is still
326 allowed for backwards compatibility, but it is not required anymore
327 when specifying the interface
328 * driver_ndis: re-initialize driver interface is the adapter is removed
329 and re-inserted [Bug 159]
330 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
331 big endian hosts [Bug 146]
334 * fixed EAP-GTC response to include correct user identity when run as
335 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
336 * driver_ndis: Fixed encryption mode configuration for unencrypted
337 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
338 refused to associate with open networks) [Bug 106]
339 * driver_ndis: use BSSID OID polling to detect when IBSS network is
340 formed even when ndis_events code is included since some NDIS drivers
341 do not generate media connect events in IBSS mode
342 * config_winreg: allow global ctrl_interface parameter to be configured
344 * config_winreg: added support for saving configuration data into
346 * added support for controlling network device operational state
347 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
348 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
349 that can use this information)
350 * driver_wext: added support for WE-21 change to SSID configuration
351 * driver_wext: fixed privacy configuration for static WEP keys mode
353 * added an optional driver_ops callback for MLME-SETPROTECTION.request
355 * added support for EAP-SAKE (no EAP method number allocated yet, so
356 this is using the same experimental type 255 as EAP-PSK)
357 * added support for dynamically loading EAP methods (.so files) instead
358 of requiring them to be statically linked in; this is disabled by
359 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
363 * do not try to use USIM APDUs when initializing PC/SC for SIM card
364 access for a network that has not enabled EAP-AKA
365 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
366 v0.5.1 due to the new support for expanded EAP types)
367 * added support for generating EAP Expanded Nak
368 * try to fetch scan results once before requesting new scan when
369 starting up in ap_scan=1 mode (this can speed up initial association
370 a lot with, e.g., madwifi-ng driver)
371 * added support for receiving EAPOL frames from a Linux bridge
372 interface (-bbr0 on command line)
373 * fixed EAPOL re-authentication for sessions that used PMKSA caching
374 * changed EAP method registration to use a dynamic list of methods
375 instead of a static list generated at build time
376 * fixed PMKSA cache deinitialization not to use freed memory when
377 removing PMKSA entries
378 * fixed a memory leak in EAP-TTLS re-authentication
379 * reject WPA/WPA2 message 3/4 if it does not include any valid
381 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
382 if the driver does not support SIOCSIWAUTH
385 * driver_test: added better support for multiple APs and STAs by using
386 a directory with sockets that include MAC address for each device in
387 the name (driver_param=test_dir=/tmp/test)
388 * added support for EAP expanded type (vendor specific EAP methods)
389 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
390 option can be changed if needed
391 * wpa_cli/wpa_gui: skip non-socket files in control directory when
392 using UNIX domain sockets; this avoids selecting an incorrect
393 interface (e.g., a PID file could be in this directory, even though
394 use of this directory for something else than socket files is not
396 * fixed TLS library deinitialization after RSN pre-authentication not
397 to disable TLS library for normal authentication
398 * driver_wext: Remove null-termination from SSID length if the driver
399 used it; some Linux drivers do this and they were causing problems in
400 wpa_supplicant not finding matching configuration block. This change
401 would break a case where the SSID actually ends in '\0', but that is
402 not likely to happen in real use.
403 * fixed PMKSA cache processing not to trigger deauthentication if the
404 current PMKSA cache entry is replaced with a valid new entry
405 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
406 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
409 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
410 * added experimental STAKey handshake implementation for IEEE 802.11e
411 direct link setup (DLS); note: this is disabled by default in both
412 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
414 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
415 decrypt AT_ENCR_DATA attributes correctly
416 * fixed EAP-AKA to allow resynchronization within the same session
417 * made code closer to ANSI C89 standard to make it easier to port to
418 other C libraries and compilers
419 * started moving operating system or C library specific functions into
420 wrapper functions defined in os.h and implemented in os_*.c to make
422 * wpa_supplicant can now be built with Microsoft Visual C++
423 (e.g., with the freely available Toolkit 2003 version or Visual
424 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
425 example makefile for nmake
426 * added support for using Windows registry for command line parameters
427 (CONFIG_MAIN=main_winsvc) and configuration data
428 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
429 contents; this version can be run both as a Windows service and as a
430 normal application; 'wpasvc.exe app' to start as applicant,
431 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
432 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
434 * made it possible to link ndis_events.exe functionality into
435 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
436 * added better support for multiple control interface backends
437 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
438 * fixed PC/SC code to use correct length for GSM AUTH command buffer
439 and to not use pioRecvPci with SCardTransmit() calls; these were not
440 causing visible problems with pcsc-lite, but Windows Winscard.dll
441 refused the previously used parameters; this fixes EAP-SIM and
442 EAP-AKA authentication using SIM/USIM card under Windows
443 * added new event loop implementation for Windows using
444 WaitForMultipleObject() instead of select() in order to allow waiting
445 for non-socket objects; this can be selected with
446 CONFIG_ELOOP=eloop_win in .config
447 * added support for selecting l2_packet implementation in .config
448 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
449 winpcap, freebsd, none)
450 * added new l2_packet implementation for WinPcap
451 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
452 reduce latency in EAPOL receive processing from about 100 ms to about
454 * added support for EAP-FAST key derivation using other ciphers than
455 RC4-128-SHA for authentication and AES128-SHA for provisioning
456 * added support for configuring CA certificate as DER file and as a
458 * fixed private key configuration as configuration blob and added
459 support for using PKCS#12 as a blob
460 * tls_gnutls: added support for using PKCS#12 files; added support for
462 * added support for loading trusted CA certificates from Windows
463 certificate store: ca_cert="cert_store://<name>", where <name> is
464 likely CA (Intermediate CA certificates) or ROOT (root certificates)
465 * added C version of ndis_events.cpp and made it possible to build this
466 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
467 easily on cross-compilation builds
468 * added wpasvc.exe into Windows binary release; this is an alternative
469 version of wpa_supplicant.exe with configuration backend using
470 Windows registry and with the entry point designed to run as a
472 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
473 wpasvc.exe and removed this additional tool from the Windows binary
474 release since it is not needed anymore
475 * load winscard.dll functions dynamically when building with MinGW
476 since MinGW does not yet include winscard library
478 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
479 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
480 and WinPcap to receive frames sent to PAE group address
481 * disable EAP state machine when IEEE 802.1X authentication is not used
482 in order to get rid of bogus "EAP failed" messages
483 * fixed OpenSSL error reporting to go through all pending errors to
484 avoid confusing reports of old errors being reported at later point
486 * fixed configuration file updating to not write empty variables
487 (e.g., proto or key_mgmt) that the file parser would not accept
488 * fixed ADD_NETWORK ctrl_iface command to use the same default values
489 for variables as empty network definitions read from config file
491 * fixed EAP state machine to not discard EAP-Failure messages in many
492 cases (e.g., during TLS handshake)
493 * fixed a infinite loop in private key reading if the configured file
494 cannot be parsed successfully
495 * driver_madwifi: added support for madwifi-ng
496 * wpa_gui: do not display password/PSK field contents
497 * wpa_gui: added CA certificate configuration
498 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
499 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
500 the new AP is using different WPA/RSN IE
501 * use longer timeout for IEEE 802.11 association to avoid problems with
502 drivers that may take more than five second to associate
505 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
506 RSN IE, but WPA IE would match with wpa_supplicant configuration
507 * added support for named configuration blobs in order to avoid having
508 to use file system for external files (e.g., certificates);
509 variables can be set to "blob://<blob name>" instead of file path to
510 use a named blob; supported fields: pac_file, client_cert,
512 * fixed RSN pre-authentication (it was broken in the clean up of WPA
513 state machine interface in v0.4.5)
514 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
515 sure the driver configures broadcast decryption correctly
516 * added ca_path (and ca_path2) configuration variables that can be used
517 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
518 system-wide trusted CA list
519 * added support for starting wpa_supplicant without a configuration
520 file (-C argument must be used to set ctrl_interface parameter for
521 this case; in addition, -p argument can be used to provide
522 driver_param; these new arguments can also be used with a
523 configuration to override the values from the configuration)
524 * added global control interface that can be optionally used for adding
525 and removing network interfaces dynamically (-g command line argument
526 for both wpa_supplicant and wpa_cli) without having to restart
527 wpa_supplicant process
529 - try to save configuration whenever something is modified
530 - added WEP key configuration
531 - added possibility to edit the current network configuration
532 * driver_ndis: fixed driver polling not to increase frequency on each
533 received EAPOL frame due to incorrectly cancelled timeout
534 * added simple configuration file examples (in examples subdirectory)
535 * fixed driver_wext.c to filter wireless events based on ifindex to
536 avoid interfaces receiving events from other interfaces
537 * delay sending initial EAPOL-Start couple of seconds to speed up
538 authentication for the most common case of Authenticator starting
539 EAP authentication immediately after association
542 * added a workaround for clearing keys with ndiswrapper to allow
543 roaming from WPA enabled AP to plaintext one
544 * added docbook documentation (doc/docbook) that can be used to
545 generate, e.g., man pages
546 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
547 PF_PACKET in order to prepare for network devices that do not use
548 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
549 * use receipt of EAPOL-Key frame as a lower layer success indication
550 for EAP state machine to allow recovery from dropped EAP-Success
552 * cleaned up internal EAPOL frame processing by not including link
553 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
554 header is added only when transmitted the frame; this makes it easier
555 to use wpa_supplicant on link layers that use different header than
557 * updated EAP-PSK to use draft 9 by default since this can now be
558 tested with hostapd; removed support for draft 3, including
559 server_nai configuration option from network blocks
560 * driver_wired: add PAE address to the multicast address list in order
561 to be able to receive EAPOL frames with drivers that do not include
562 these multicast addresses by default
563 * driver_wext: add support for WE-19
564 * added support for multiple configuration backends (CONFIG_BACKEND
565 option); currently, only 'file' is supported (i.e., the format used
566 in wpa_supplicant.conf)
567 * added support for updating configuration ('wpa_cli save_config');
568 this is disabled by default and can be enabled with global
569 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
570 and wpa_gui to store the configuration changes in a permanent store
571 * added GET_NETWORK ctrl_iface command
572 (e.g., 'wpa_cli get_network 0 ssid')
575 * replaced OpenSSL patch for EAP-FAST support
576 (openssl-tls-extensions.patch) with a more generic and correct
577 patch (the new patch is not compatible with the previous one, so the
578 OpenSSL library will need to be patched with the new patch in order
579 to be able to build wpa_supplicant with EAP-FAST support)
580 * added support for using Windows certificate store (through CryptoAPI)
581 for client certificate and private key operations (EAP-TLS)
582 (see wpa_supplicant.conf for more information on how to configure
583 this with private_key)
584 * ported wpa_gui to Windows
585 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
586 built with the open source version of the Qt4 for Windows
587 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
588 with drivers that do not support WPA
589 * ndis_events: fixed Windows 2000 support
590 * added support for enabling/disabling networks from the list of all
591 configured networks ('wpa_cli enable_network <network id>' and
592 'wpa_cli disable_network <network id>')
593 * added support for adding and removing network from the current
594 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
595 <network id>'); added networks are disabled by default and they can
596 be enabled with enable_network command once the configuration is done
597 for the new network; note: configuration file is not yet updated, so
598 these new networks are lost when wpa_supplicant is restarted
599 * added support for setting network configuration parameters through
600 the control interface, for example:
601 wpa_cli set_network 0 ssid "\"my network\""
602 * fixed parsing of strings that include both " and # within double
603 quoted area (e.g., "start"#end")
604 * added EAP workaround for PEAP session resumption: allow outer,
605 i.e., not tunneled, EAP-Success to terminate session since; this can
606 be disabled with eap_workaround=0
607 (this was allowed for PEAPv1 before, but now it is also allowed for
608 PEAPv0 since at least one RADIUS authentication server seems to be
609 doing this for PEAPv0, too)
610 * wpa_gui: added preliminary support for adding new networks to the
611 wpa_supplicant configuration (double click on the scan results to
612 open network configuration)
615 * removed interface for external EAPOL/EAP supplicant (e.g.,
616 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
617 anymore and is unlikely to be used by anyone
618 * driver_ndis: fixed WinPcap 3.0 support
619 * fixed build with CONFIG_DNET_PCAP=y on Linux
620 * l2_packet: moved different implementations into separate files
624 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
625 (note: ipw2100-1.1.0 is likely to require an update to work with
627 * added support for using ap_scan=2 mode with multiple network blocks;
628 wpa_supplicant will go through the networks one by one until the
629 driver reports a successful association; this uses the same order for
630 networks as scan_ssid=1 scans, i.e., the priority field is ignored
631 and the network block order in the file is used instead
632 * fixed a potential issue in RSN pre-authentication ending up using
633 freed memory if pre-authentication times out
634 * added support for matching alternative subject name extensions of the
635 authentication server certificate; new configuration variables
636 altsubject_match and altsubject_match2
637 * driver_ndis: added support for IEEE 802.1X authentication with wired
639 * added support for querying private key password (EAP-TLS) through the
640 control interface (wpa_cli/wpa_gui) if one is not included in the
642 * driver_broadcom: fixed couple of memory leaks in scan result
644 * EAP-PAX is now registered as EAP type 46
645 * fixed EAP-PAX MAC calculation
646 * fixed EAP-PAX CK and ICK key derivation
647 * added support for using password with EAP-PAX (as an alternative to
648 entering key with eappsk); SHA-1 hash of the password will be used as
650 * added support for arbitrary driver interface parameters through the
651 configuration file with a new driver_param field; this adds a new
652 driver_ops function set_param()
653 * added possibility to override l2_packet module with driver interface
654 API (new send_eapol handler); this can be used to implement driver
655 specific TX/RX functions for EAPOL frames
656 * fixed ctrl_interface_group processing for the case where gid is
657 entered as a number, not group name
658 * driver_test: added support for testing hostapd with wpa_supplicant
659 by using test driver interface without any kernel drivers or network
663 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
664 packets to be encrypted; this was apparently broken by the changed
665 ioctl order in v0.4.0
666 * driver_madwifi: added preliminary support for compiling against 'BSD'
667 branch of madwifi CVS tree
668 * added support for EAP-MSCHAPv2 password retries within the same EAP
669 authentication session
670 * added support for password changes with EAP-MSCHAPv2 (used when the
671 password has expired)
672 * added support for reading additional certificates from PKCS#12 files
673 and adding them to the certificate chain
674 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
676 * fixed a possible double free in EAP-TTLS fast-reauthentication when
677 identity or password is entered through control interface
678 * display EAP Notification messages to user through control interface
679 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
680 * added GUI version of wpa_cli, wpa_gui; this is not build
681 automatically with 'make'; use 'make wpa_gui' to build (this requires
682 Qt development tools)
683 * added 'disconnect' command to control interface for setting
684 wpa_supplicant in state where it will not associate before
685 'reassociate' command has been used
686 * added support for selecting a network from the list of all configured
687 networks ('wpa_cli select_network <network id>'; this disabled all
688 other networks; to re-enable, 'wpa_cli select_network any')
689 * added support for getting scan results through control interface
690 * added EAP workaround for PEAPv1 session resumption: allow outer,
691 i.e., not tunneled, EAP-Success to terminate session since; this can
692 be disabled with eap_workaround=0
694 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
695 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
696 used to reduce the size of the wpa_supplicant considerably if
697 debugging code is not needed
698 * fixed EAPOL-Key validation to drop packets with invalid Key Data
699 Length; such frames could have crashed wpa_supplicant due to buffer
701 * added support for wired authentication (IEEE 802.1X on wired
702 Ethernet); driver interface 'wired'
703 * obsoleted set_wpa() handler in the driver interface API (it can be
704 replaced by moving enable/disable functionality into init()/deinit())
705 (calls to set_wpa() are still present for backwards compatibility,
706 but they may be removed in the future)
707 * driver_madwifi: fixed association in plaintext mode
708 * modified the EAP workaround that accepts EAP-Success with incorrect
709 Identifier to be even less strict about verification in order to
710 interoperate with some authentication servers
711 * added support for sending TLS alerts
712 * added support for 'any' SSID wildcard; if ssid is not configured or
713 is set to an empty string, any SSID will be accepted for non-WPA AP
714 * added support for asking PIN (for SIM) from frontends (e.g.,
715 wpa_cli); if a PIN is needed, but not included in the configuration
716 file, a control interface request is sent and EAP processing is
717 delayed until the PIN is available
718 * added support for using external devices (e.g., a smartcard) for
719 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
720 new wpa_supplicant.conf variables:
721 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
722 - network: engine, engine_id, key_id
723 * added experimental support for EAP-PAX
724 * added monitor mode for wpa_cli (-a<path to a program to run>) that
725 allows external commands (e.g., shell scripts) to be run based on
726 wpa_supplicant events, e.g., when authentication has been completed
727 and data connection is ready; other related wpa_cli arguments:
728 -B (run in background), -P (write PID file); wpa_supplicant has a new
729 command line argument (-W) that can be used to make it wait until a
730 control interface command is received in order to avoid missing
732 * added support for opportunistic WPA2 PMKSA key caching (disabled by
733 default, can be enabled with proactive_key_caching=1)
734 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
735 Authenticator rejects PMKSA caching attempt and the driver is not
736 using assoc_info events
737 * added -P<pid file> argument for wpa_supplicant to write the current
738 process id into a file
740 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
741 * added new phase1 option parameter, include_tls_length=1, to force
742 wpa_supplicant to add TLS Message Length field to all TLS messages
743 even if the packet is not fragmented; this may be needed with some
744 authentication servers
745 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
746 using drivers that take care of AP selection (e.g., when using
748 * fixed reprocessing of pending request after ctrl_iface requests for
749 identity/password/otp
750 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
751 EAP-PEAP and EAP-TTLS
752 * all drivers using driver_wext: set interface up and select Managed
753 mode when starting wpa_supplicant; set interface down when exiting
754 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
755 ipw2100 and ipw2200; please note that this also changed the
756 configuration variable in .config to CONFIG_DRIVER_IPW
759 * fixed a busy loop introduced in v0.3.5 for scan result processing
760 when no matching AP is found
763 * added a workaround for an interoperability issue with a Cisco AP
765 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
766 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
767 retransmission of dropped frames)
768 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
769 (e.g., segfault when processing EAPOL-Key frames)
770 * fixed EAP workaround and fast reauthentication configuration for
771 RSN pre-authentication; previously these were disabled and
772 pre-authentication would fail if the used authentication server
773 requires EAP workarounds
774 * added support for blacklisting APs that fail or timeout
775 authentication in ap_scan=1 mode so that all APs are tried in cases
776 where the ones with strongest signal level are failing authentication
777 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
778 authentication attempt
779 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
780 in the previous authentication (previously, only Phase 1 success was
784 * added preliminary support for IBSS (ad-hoc) mode configuration
785 (mode=1 in network block); this included a new key_mgmt mode
786 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
787 key management; see wpa_supplicant.conf for more details and an
788 example on how to configure this (note: this is currently implemented
789 only for driver_hostapd.c, but the changes should be trivial to add
790 in associate() handler for other drivers, too (assuming the driver
792 * added preliminary port for native Windows (i.e., no cygwin) using
796 * added optional support for GNU Readline and History Libraries for
797 wpa_cli (CONFIG_READLINE)
798 * cleaned up EAP state machine <-> method interface and number of
799 small problems with error case processing not terminating on
800 EAP-Failure but waiting for timeout
801 * added couple of workarounds for interoperability issues with a
802 Cisco AP when using WPA2
803 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
804 Note: This requires a patch for openssl to add support for TLS
805 extensions and number of workarounds for operations without
806 certificates. Proof of concept type of experimental patch is
807 included in openssl-tls-extensions.patch.
810 * fixed private key loading for cases where passphrase is not set
811 * fixed Windows/cygwin L2 packet handler freeing; previous version
812 could cause a segfault when RSN pre-authentication was completed
813 * added support for PMKSA caching with drivers that generate RSN IEs
814 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
815 but similar code can be easily added to driver_ndiswrapper.c once
816 ndiswrapper gets full support for RSN PMKSA caching
817 * improved recovery from PMKID mismatches by requesting full EAP
818 authentication in case of failed PMKSA caching attempt
819 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
820 (this requires that ndis_events is ran while wpa_supplicant is
822 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
823 * added support for driver interfaces to replace the interface name
824 based on driver/OS specific mapping, e.g., in case of driver_ndis,
825 this allows the beginning of the adapter description to be used as
827 * added support for CR+LF (Windows-style) line ends in configuration
829 * driver_ndis: enable radio before starting scanning, disable radio
831 * modified association event handler to set portEnabled = FALSE before
832 clearing port Valid in order to reset EAP state machine and avoid
833 problems with new authentication getting ignored because of state
834 machines ending up in AUTHENTICATED/SUCCESS state based on old
836 * added support for driver events to add PMKID candidates in order to
837 allow drivers to give priority to most likely roaming candidates
838 * driver_hostap: moved PrivacyInvoked configuration to associate()
839 function so that this will not be set for plaintext connections
840 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
841 interface can distinguish plaintext and IEEE 802.1X (no WPA)
843 * fixed static WEP key configuration to use broadcast/default type for
844 all keys (previously, the default TX key was configured as pairwise/
846 * driver_ndis: added legacy WPA capability detection for non-WPA2
848 * added support for setting static WEP keys for IEEE 802.1X without
849 dynamic WEP keying (eapol_flags=0)
852 * added support for reading PKCS#12 (PFX) files (as a replacement for
853 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
854 * fixed compilation with CONFIG_PCSC=y
855 * added new ap_scan mode, ap_scan=2, for drivers that take care of
856 association, but need to be configured with security policy and SSID,
857 e.g., ndiswrapper and NDIS driver; this mode should allow such
858 drivers to work with hidden SSIDs and optimized roaming; when
859 ap_scan=2 is used, only the first network block in the configuration
860 file is used and this configuration should have explicit security
861 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
862 group, proto variables
863 * added experimental port of wpa_supplicant for Windows
864 - driver_ndis.c driver interface (NDIS OIDs)
865 - currently, this requires cygwin and WinPcap
866 - small utility, win_if_list, can be used to get interface name
867 * control interface can now be removed at build time; add
868 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
869 * optional Xsupplicant interface can now be removed at build time;
870 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
871 * added auth_alg to driver interface associate() parameters to make it
872 easier for drivers to configure authentication algorithm as part of
875 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
876 * driver_broadcom: added new driver interface for Broadcom wl.o driver
877 (a generic driver for Broadcom IEEE 802.11a/g cards)
878 * wpa_cli: fixed parsing of -p <path> command line argument
879 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
880 ACK, not tunneled EAP-Success (of which only the first byte was
881 actually send due to a bug in previous code); this seems to
882 interoperate with most RADIUS servers that implements PEAPv1
883 * PEAPv1: added support for terminating PEAP authentication on tunneled
884 EAP-Success message; this can be configured by adding
885 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
886 (some RADIUS servers require this whereas others require a tunneled
888 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
889 the old label for key derivation; previously, the default was 1,
890 but it looks like most existing PEAPv1 implementations use the old
891 label which is thus more suitable default option
892 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
893 * fixed parsing of wep_tx_keyidx
894 * added support for configuring list of allowed Phase 2 EAP types
895 (for both EAP-PEAP and EAP-TTLS) instead of only one type
896 * added support for configuring IEEE 802.11 authentication algorithm
897 (auth_alg; mainly for using Shared Key authentication with static
899 * added support for EAP-AKA (with UMTS SIM)
900 * fixed couple of errors in PCSC handling that could have caused
901 random-looking errors for EAP-SIM
902 * added support for EAP-SIM pseudonyms and fast re-authentication
903 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
905 * added support for EAP-SIM with two challanges
906 (phase1="sim_min_num_chal=3" can be used to require three challenges)
907 * added support for configuring DH/DSA parameters for an ephemeral DH
908 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
909 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
910 and optional DH key exchange to achieve forward secracy with RSA keys
911 * added support for matching subject of the authentication server
912 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
913 configuration variables subject_match and subject_match2
914 * changed SSID configuration in driver_wext.c (used by many driver
915 interfaces) to use ssid_len+1 as the length for SSID since some Linux
917 * fixed couple of unaligned reads in scan result parsing to fix WPA
918 connection on some platforms (e.g., ARM)
919 * added driver interface for Intel ipw2100 driver
920 * added support for LEAP with WPA
921 * added support for larger scan results report (old limit was 4 kB of
922 data, i.e., about 35 or so APs) when using Linux wireless extensions
924 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
925 only if there is a PMKSA cache entry for the current AP
926 * fixed error handling for case where reading of scan results fails:
927 must schedule a new scan or wpa_supplicant will remain waiting
929 * changed debug output to remove shared password/key material by
930 default; all key information can be included with -K command line
931 argument to match the previous behavior
932 * added support for timestamping debug log messages (disabled by
933 default, can be enabled with -t command line argument)
934 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
935 if keys are not configured to be used; this fixes IEEE 802.1X mode
936 with drivers that use this information to configure whether Privacy
937 bit can be in Beacon frames (e.g., ndiswrapper)
938 * avoid clearing driver keys if no keys have been configured since last
939 key clear request; this seems to improve reliability of group key
940 handshake for ndiswrapper & NDIS driver which seems to be suffering
941 of some kind of timing issue when the keys are cleared again after
943 * changed driver interface API:
944 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
945 version is being used (now, this is set to 2; previously, it was
947 - pass pointer to private data structure to all calls
948 - the new API is not backwards compatible; all in-tree driver
949 interfaces has been converted to the new API
950 * added support for controlling multiple interfaces (radios) per
951 wpa_supplicant process; each interface needs to be listed on the
952 command line (-c, -i, -D arguments) with -N as a separator
953 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
954 * added a workaround for EAP servers that incorrectly use same Id for
955 sequential EAP packets
956 * changed libpcap/libdnet configuration to use .config variable,
957 CONFIG_DNET_PCAP, instead of requiring Makefile modification
958 * improved downgrade attack detection in IE verification of msg 3/4:
959 verify both WPA and RSN IEs, if present, not only the selected one;
960 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
961 Probe Response frame, and RSN is enabled in wpa_supplicant
963 * fixed WPA msg 3/4 processing to allow Key Data field contain other
964 IEs than just one WPA IE
965 * added support for FreeBSD and driver interface for the BSD net80211
966 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
967 required kernel mods have not yet been committed
968 * made EAP workarounds configurable; enabled by default, can be
969 disabled with network block option eap_workaround=0
971 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
972 * resolved couple of interoperability issues with EAP-PEAPv1 and
973 Phase 2 (inner EAP) fragment reassembly
974 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
975 AP is using non-zero key index for the unicast key and key index zero
976 for the broadcast key
977 * driver_hostap: fixed IEEE 802.1X WEP key updates and
978 re-authentication by allowing unencrypted EAPOL frames when not using
980 * added a new driver interface, 'wext', which uses only standard,
981 driver independent functionality in Linux wireless extensions;
982 currently, this can be used only for non-WPA IEEE 802.1X mode, but
983 eventually, this is to be extended to support full WPA/WPA2 once
984 Linux wireless extensions get support for this
985 * added support for mode in which the driver is responsible for AP
986 scanning and selection; this is disabled by default and can be
987 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
988 this mode can be used, e.g., with generic 'wext' driver interface to
989 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
990 supporting wireless extensions.
991 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
992 operation with an AP that does not include SSID in the Beacon frames)
993 * added support for new EAP authentication methods:
994 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
995 * added support for asking one-time-passwords from frontends (e.g.,
996 wpa_cli); this 'otp' command works otherwise like 'password' command,
997 but the password is used only once and the frontend will be asked for
998 a new password whenever a request from authenticator requires a
999 password; this can be used with both EAP-OTP and EAP-GTC
1000 * changed wpa_cli to automatically re-establish connection so that it
1001 does not need to be re-started when wpa_supplicant is terminated and
1003 * improved user data (identity/password/otp) requests through
1004 frontends: process pending EAPOL packets after getting new
1005 information so that full authentication does not need to be
1006 restarted; in addition, send pending requests again whenever a new
1007 frontend is attached
1008 * changed control frontends to use a new directory for socket files to
1009 make it easier for wpa_cli to automatically select between interfaces
1010 and to provide access control for the control interface;
1011 wpa_supplicant.conf: ctrl_interface is now a path
1012 (/var/run/wpa_supplicant is the recommended path) and
1013 ctrl_interface_group can be used to select which group gets access to
1014 the control interface;
1015 wpa_cli: by default, try to connect to the first interface available
1016 in /var/run/wpa_supplicant; this path can be overriden with -p option
1017 and an interface can be selected with -i option (i.e., in most common
1018 cases, wpa_cli does not need to get any arguments)
1019 * added support for LEAP
1020 * added driver interface for Linux ndiswrapper
1021 * added priority option for network blocks in the configuration file;
1022 this allows networks to be grouped based on priority (the scan
1023 results are searched for matches with network blocks in this order)
1026 * sort scan results to improve AP selection
1027 * fixed control interface socket removal for some error cases
1028 * improved scan requesting and authentication timeout
1029 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1031 * PEAP version can now be forced with phase1="peapver=<ver>"
1032 (mostly for testing; by default, the highest version supported by
1033 both the Supplicant and Authentication Server is selected
1035 * added support for madwifi driver (Atheros ar521x)
1036 * added a workaround for cases where AP sets Install Tx/Rx bit for
1037 WPA Group Key messages when pairwise keys are used (without this,
1038 the Group Key would be used for Tx and the AP would drop frames
1040 * added GSM SIM/USIM interface for GSM authentication algorithm for
1041 EAP-SIM; this requires pcsc-lite
1042 * added support for ATMEL AT76C5XXx driver
1043 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1044 does not include key data in the EAPOL-Key frame (i.e., part of
1045 EAP keying material is used as data encryption key)
1046 * added support for using plaintext and static WEP networks
1050 * added support for new EAP authentication methods:
1051 EAP-TTLS/EAP-MD5-Challenge
1053 EAP-TTLS/EAP-MSCHAPv2
1061 EAP-PEAP/MD5-Challenge
1063 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1064 * added support for anonymous identity (to be used when identity is
1065 sent in plaintext; real identity will be used within TLS protected
1066 tunnel (e.g., with EAP-TTLS)
1067 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1068 * added support for requesting identity and password information using
1069 control interface; in other words, the password for EAP-PEAP or
1070 EAP-TTLS does not need to be included in the configuration file since
1071 a frontand (e.g., wpa_cli) can ask it from the user
1072 * improved RSN pre-authentication to use a candidate list and process
1073 all candidates from each scan; not only one per scan
1074 * fixed RSN IE and WPA IE capabilities field parsing
1075 * ignore Tx bit in GTK IE when Pairwise keys are used
1076 * avoid making new scan requests during IEEE 802.1X negotiation
1077 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1078 with TLS support (this replaces the included implementation with
1079 library code to save about 8 kB since the library code is needed
1081 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1082 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1085 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1087 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1088 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1089 - EAP-MD5 (cannot be used with WPA-RADIUS)
1090 [draft-ietf-eap-rfc2284bis-09.txt]
1091 - EAP-TLS [RFC 2716]
1092 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1093 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1094 [draft-kamath-pppext-eap-mschapv2-00.txt]
1095 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1096 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1097 - new configuration file options: eap, identity, password, ca_cert,
1098 client_cert, privatekey, private_key_passwd
1099 - Xsupplicant is not required anymore, but it can be used by
1100 disabling the internal IEEE 802.1X Supplicant with -e command line
1102 - this code is not included in the default build; Makefile need to
1103 be edited for this (uncomment lines for selected functionality)
1104 - EAP-TLS and EAP-PEAP require openssl libraries
1105 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1106 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1107 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1108 EAPOL-Key frames instead of WPA key handshakes)
1109 * added support for IEEE 802.11i/RSN (WPA2)
1110 - improved PTK Key Handshake
1111 - PMKSA caching, pre-authentication
1112 * fixed wpa_supplicant to ignore possible extra data after WPA
1113 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1114 TPTK' error from message 3 of 4-Way Handshake in case the AP
1115 includes extra data after the EAPOL-Key)
1116 * added interface for external programs (frontends) to control
1118 - CLI example (wpa_cli) with interactive mode and command line
1120 - replaced SIGUSR1 status/statistics with the new control interface
1121 * made some feature compile time configurable
1122 - .config file for make
1123 - driver interfaces (hostap, hermes, ..)
1124 - EAPOL/EAP functions
1127 * Initial version of wpa_supplicant
