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 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
15 * added support for SHA-256 as X.509 certificate digest when using the
16 internal X.509/TLSv1 implementation
17 * updated management frame protection to use IEEE 802.11w/D6.0
18 * added support for using SHA256-based stronger key derivation for WPA2
20 * fixed FT (IEEE 802.11r) authentication after a failed association to
22 * added support for configuring Phase 2 (inner/tunneled) authentication
23 method with wpa_gui-qt4
26 * added support for EAP Sequences in EAP-FAST Phase 2
27 * added support for using TNC with EAP-FAST
28 * added driver_ps3 for the PS3 Linux wireless driver
29 * added support for optional cryptobinding with PEAPv0
30 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
31 allow fallback to full handshake if server rejects PAC-Opaque
32 * added fragmentation support for EAP-TNC
33 * added support for parsing PKCS #8 formatted private keys into the
34 internal TLS implementation (both PKCS #1 RSA key and PKCS #8
35 encapsulated RSA key can now be used)
36 * added option of using faster, but larger, routines in the internal
37 LibTomMath (for internal TLS implementation) to speed up DH and RSA
38 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
39 * fixed race condition between disassociation event and group key
40 handshake to avoid getting stuck in incorrect state [Bug 261]
41 * fixed opportunistic key caching (proactive_key_caching)
44 * removed 'nai' and 'eappsk' network configuration variables that were
45 previously used for configuring user identity and key for EAP-PSK,
46 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
47 replacement for 'nai' (if old configuration used a separate
48 'identity' value, that would now be configured as
49 'anonymous_identity'). 'password' field is now used as the
50 replacement for 'eappsk' (it can also be set using hexstring to
51 present random binary data)
52 * removed '-w' command line parameter (wait for interface to be added,
53 if needed); cleaner way of handling this functionality is to use an
54 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
55 when an interface is added
56 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
57 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
58 indicating when new scan results become available
59 * added new ctrl_iface command, BSS, to allow scan results to be
60 fetched without hitting the message size limits (this command
61 can be used to iterate through the scan results one BSS at the time)
62 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
63 attributes in EAP-SIM Start/Response when using fast reauthentication
64 * fixed EAPOL not to end up in infinite loop when processing dynamic
65 WEP keys with IEEE 802.1X
66 * fixed problems in getting NDIS events from WMI on Windows 2000
69 * added support for Makefile builds to include debug-log-to-a-file
70 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
71 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
72 lengths properly to avoid potential crash caused by invalid messages
73 * added data structure for storing allocated buffers (struct wpabuf);
74 this does not affect wpa_supplicant usage, but many of the APIs
75 changed and various interfaces (e.g., EAP) is not compatible with old
77 * added support for protecting EAP-AKA/Identity messages with
78 AT_CHECKCODE (optional feature in RFC 4187)
79 * added support for protected result indication with AT_RESULT_IND for
80 EAP-SIM and EAP-AKA (phase1="result_ind=1")
81 * added driver_wext workaround for race condition between scanning and
82 association with drivers that take very long time to scan all
83 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
84 using a longer hardcoded timeout for the scan if the driver supports
85 notifications for scan completion (SIOCGIWSCAN event); this helps,
86 e.g., in cases where wpa_supplicant and madwifi driver ended up in
87 loop where the driver did not even try to associate
88 * stop EAPOL timer tick when no timers are in use in order to reduce
89 power consumption (no need to wake up the process once per second)
91 * added support for privilege separation (run only minimal part of
92 wpa_supplicant functionality as root and rest as unprivileged,
93 non-root process); see 'Privilege separation' in README for details;
94 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
96 * changed scan results data structure to include all information
97 elements to make it easier to support new IEs; old get_scan_result()
98 driver_ops is still supported for backwards compatibility (results
99 are converted internally to the new format), but all drivers should
100 start using the new get_scan_results2() to make them more likely to
101 work with new features
102 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
103 application, i.e., it does not require Qt3Support anymore; Windows
104 binary of wpa_gui.exe is now from this directory and only requires
105 QtCore4.dll and QtGui4.dll libraries
106 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
107 available as a separate package to make wpa_gui installation easier:
108 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
109 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
110 only shared key/password authentication is supported in this version
113 * added support for configuring password as NtPasswordHash
114 (16-byte MD4 hash of password) in hash:<32 hex digits> format
115 * added support for fallback from abbreviated TLS handshake to
116 full handshake when using EAP-FAST (e.g., due to an expired
118 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
119 draft (draft-ietf-emu-eap-gpsk-07.txt)
120 * added support for drivers that take care of RSN 4-way handshake
121 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
122 WPA_ALG_PMK in set_key)
123 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
124 .config); this version supports only ap_scan=2 mode and allow the
125 driver to take care of the 4-way handshake
126 * fixed a buffer overflow in parsing TSF from scan results when using
127 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
129 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
130 * fixed an integer overflow issue in the ASN.1 parser used by the
131 (experimental) internal TLS implementation to avoid a potential
133 * fixed a race condition with -W option (wait for a control interface
134 monitor before starting) that could have caused the first messages to
136 * added support for processing TNCC-TNCS-Messages to report
137 recommendation (allow/none/isolate) when using TNC [Bug 243]
140 * added network configuration parameter 'frequency' for setting
141 initial channel for IBSS (adhoc) networks
142 * added experimental IEEE 802.11r/D6.0 support
143 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
144 * updated EAP-PSK to use the IANA-allocated EAP type 47
145 * fixed EAP-PAX key derivation
146 * fixed EAP-PSK bit ordering of the Flags field
147 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
148 tunnelled identity request (previously, the identifier from the outer
149 method was used, not the tunnelled identifier which could be
151 * added support for fragmentation of outer TLS packets during Phase 2
152 of EAP-PEAP/TTLS/FAST
153 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
154 * added support for EAP-FAST authentication with inner methods that
155 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
156 for PAC provisioning)
157 * added support for authenticated EAP-FAST provisioning
158 * added support for configuring maximum number of EAP-FAST PACs to
159 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
160 * added support for storing EAP-FAST PACs in binary format
161 (fast_pac_format=binary in phase1 string)
162 * fixed dbus ctrl_iface to validate message interface before
163 dispatching to avoid a possible segfault [Bug 190]
164 * fixed PeerKey key derivation to use the correct PRF label
165 * updated Windows binary build to link against OpenSSL 0.9.8d and
166 added support for EAP-FAST
167 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
168 draft (draft-ietf-emu-eap-gpsk-04.txt)
169 * fixed EAP-AKA Notification processing to allow Notification to be
170 processed after AKA Challenge response has been sent
171 * updated to use IEEE 802.11w/D2.0 for management frame protection
173 * fixed EAP-TTLS implementation not to crash on use of freed memory
174 if TLS library initialization fails
175 * added support for EAP-TNC (Trusted Network Connect)
176 (this version implements the EAP-TNC method and EAP-TTLS changes
177 needed to run two methods in sequence (IF-T) and the IF-IMC and
178 IF-TNCCS interfaces from TNCC)
181 * added experimental, integrated TLSv1 client implementation with the
182 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
183 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
184 .config); this can be useful, e.g., if the target system does not
185 have a suitable TLS library and a minimal code size is required
186 (total size of this internal TLS/crypto code is bit under 50 kB on
187 x86 and the crypto code is shared by rest of the supplicant so some
188 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
189 * removed STAKey handshake since PeerKey handshake has replaced it in
190 IEEE 802.11ma and there are no known deployments of STAKey
191 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
192 draft (draft-ietf-emu-eap-gpsk-01.txt)
193 * added preliminary implementation of IEEE 802.11w/D1.0 (management
195 (Note: this requires driver support to work properly.)
196 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
197 * fixed Windows named pipes ctrl_iface to not stop listening for
198 commands if client program opens a named pipe and closes it
199 immediately without sending a command
200 * fixed USIM PIN status determination for the case that PIN is not
201 needed (this allows EAP-AKA to be used with USIM cards that do not
203 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
204 be used with cards that do not support file selection based on
206 * added support for matching the subjectAltName of the authentication
207 server certificate against multiple name components (e.g.,
208 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
209 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
210 affects IEEE 802.1X with dynamic WEP keys)
211 * changed ctrl_iface network configuration 'get' operations to not
212 return password/key material; if these fields are requested, "*"
213 will be returned if the password/key is set, but the value of the
214 parameter is not exposed
217 * added support for building Windows version with UNICODE defined
218 (wide-char functions)
219 * driver_ndis: fixed static WEP configuration to avoid race condition
220 issues with some NDIS drivers between association and setting WEP
222 * driver_ndis: added validation for IELength value in scan results to
223 avoid crashes when using buggy NDIS drivers [Bug 165]
224 * fixed Release|Win32 target in the Visual Studio project files
225 (previously, only Debug|Win32 target was set properly)
226 * changed control interface API call wpa_ctrl_pending() to allow it to
227 return -1 on error (e.g., connection lost); control interface clients
228 will need to make sure that they verify that the value is indeed >0
229 when determining whether there are pending messages
230 * added an alternative control interface backend for Windows targets:
231 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
232 control interface mechanism for Windows builds (previously, UDP to
234 * changed ctrl_interface configuration for UNIX domain sockets:
235 - deprecated ctrl_interface_group variable (it may be removed in
237 - allow both directory and group be configured with ctrl_interface
238 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
239 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
240 case when group is not changed
241 * added support for controlling more than one interface per process in
243 * added a workaround for a case where the AP is using unknown address
244 (e.g., MAC address of the wired interface) as the source address for
245 EAPOL-Key frames; previously, that source address was used as the
246 destination for EAPOL-Key frames and in key derivation; now, BSSID is
247 used even if the source address does not match with it
248 (this resolves an interoperability issue with Thomson SpeedTouch 580)
249 * added a workaround for UDP-based control interface (which was used in
250 Windows builds before this release) to prevent packets with forged
251 addresses from being accepted as local control requests
252 * removed ndis_events.cpp and possibility of using external
253 ndis_events.exe; C version (ndis_events.c) is fully functional and
254 there is no desire to maintain two separate versions of this
256 * ndis_events: Changed NDIS event notification design to use WMI to
257 learn the adapter description through Win32_PnPEntity class; this
258 should fix some cases where the adapter name was not recognized
259 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
261 * fixed selection of the first network in ap_scan=2 mode; previously,
262 wpa_supplicant could get stuck in SCANNING state when only the first
263 network for enabled (e.g., after 'wpa_cli select_network 0')
264 * winsvc: added support for configuring ctrl_interface parameters in
265 registry (ctrl_interface string value in
266 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
267 required to enable control interface (previously, this was hardcoded
269 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
270 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
273 * fixed build with CONFIG_STAKEY=y [Bug 143]
274 * added support for doing MLME (IEEE 802.11 management frame
275 processing) in wpa_supplicant when using Devicescape IEEE 802.11
276 stack (wireless-dev.git tree)
277 * added a new network block configuration option, fragment_size, to
278 configure the maximum EAP fragment size
279 * driver_ndis: Disable WZC automatically for the selected interface to
280 avoid conflicts with two programs trying to control the radio; WZC
281 will be re-enabled (if it was enabled originally) when wpa_supplicant
283 * added an experimental TLSv1 client implementation
284 (CONFIG_TLS=internal) that can be used instead of an external TLS
285 library, e.g., to reduce total size requirement on systems that do
286 not include any TLS library by default (this is not yet complete;
287 basic functionality is there, but certificate validation is not yet
289 * added PeerKey handshake implementation for IEEE 802.11e
290 direct link setup (DLS) to replace STAKey handshake
291 * fixed WPA PSK update through ctrl_iface for the case where the old
292 PSK was derived from an ASCII passphrase and the new PSK is set as
293 a raw PSK (hex string)
294 * added new configuration option for identifying which network block
295 was used (id_str in wpa_supplicant.conf; included on
296 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
297 variable in wpa_cli action scripts; in addition WPA_ID variable is
298 set to the current unique identifier that wpa_supplicant assigned
299 automatically for the network and that can be used with
300 GET_NETWORK/SET_NETWORK ctrl_iface commands)
301 * wpa_cli action script is now called only when the connect/disconnect
302 status changes or when associating with a different network
303 * fixed configuration parser not to remove CCMP from group cipher list
304 if WPA-None (adhoc) is used (pairwise=NONE in that case)
305 * fixed integrated NDIS events processing not to hang the process due
306 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
307 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
308 draft-clancy-emu-eap-shared-secret-00.txt)
309 * added Microsoft Visual Studio 2005 solution and project files for
310 build wpa_supplicant for Windows (see vs2005 subdirectory)
311 * eloop_win: fixed unregistration of Windows events
312 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
313 at the end of RSN pre-authentication and added unregistration of
314 a Windows event to avoid getting eloop_win stuck with an invalid
316 * driver_ndis: added support for selecting AP based on BSSID
317 * added new environmental variable for wpa_cli action scripts:
318 WPA_CTRL_DIR is the current control interface directory
319 * driver_ndis: added support for using NDISUIO instead of WinPcap for
320 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
321 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
322 wpa_supplicant without requiring WinPcap; note that using NDISUIO
323 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
324 only one application to open the device
325 * changed NDIS driver naming to only include device GUID, e.g.,
326 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
327 specific \Device\NPF_ prefix before the GUID; the prefix is still
328 allowed for backwards compatibility, but it is not required anymore
329 when specifying the interface
330 * driver_ndis: re-initialize driver interface is the adapter is removed
331 and re-inserted [Bug 159]
332 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
333 big endian hosts [Bug 146]
336 * fixed EAP-GTC response to include correct user identity when run as
337 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
338 * driver_ndis: Fixed encryption mode configuration for unencrypted
339 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
340 refused to associate with open networks) [Bug 106]
341 * driver_ndis: use BSSID OID polling to detect when IBSS network is
342 formed even when ndis_events code is included since some NDIS drivers
343 do not generate media connect events in IBSS mode
344 * config_winreg: allow global ctrl_interface parameter to be configured
346 * config_winreg: added support for saving configuration data into
348 * added support for controlling network device operational state
349 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
350 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
351 that can use this information)
352 * driver_wext: added support for WE-21 change to SSID configuration
353 * driver_wext: fixed privacy configuration for static WEP keys mode
355 * added an optional driver_ops callback for MLME-SETPROTECTION.request
357 * added support for EAP-SAKE (no EAP method number allocated yet, so
358 this is using the same experimental type 255 as EAP-PSK)
359 * added support for dynamically loading EAP methods (.so files) instead
360 of requiring them to be statically linked in; this is disabled by
361 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
365 * do not try to use USIM APDUs when initializing PC/SC for SIM card
366 access for a network that has not enabled EAP-AKA
367 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
368 v0.5.1 due to the new support for expanded EAP types)
369 * added support for generating EAP Expanded Nak
370 * try to fetch scan results once before requesting new scan when
371 starting up in ap_scan=1 mode (this can speed up initial association
372 a lot with, e.g., madwifi-ng driver)
373 * added support for receiving EAPOL frames from a Linux bridge
374 interface (-bbr0 on command line)
375 * fixed EAPOL re-authentication for sessions that used PMKSA caching
376 * changed EAP method registration to use a dynamic list of methods
377 instead of a static list generated at build time
378 * fixed PMKSA cache deinitialization not to use freed memory when
379 removing PMKSA entries
380 * fixed a memory leak in EAP-TTLS re-authentication
381 * reject WPA/WPA2 message 3/4 if it does not include any valid
383 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
384 if the driver does not support SIOCSIWAUTH
387 * driver_test: added better support for multiple APs and STAs by using
388 a directory with sockets that include MAC address for each device in
389 the name (driver_param=test_dir=/tmp/test)
390 * added support for EAP expanded type (vendor specific EAP methods)
391 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
392 option can be changed if needed
393 * wpa_cli/wpa_gui: skip non-socket files in control directory when
394 using UNIX domain sockets; this avoids selecting an incorrect
395 interface (e.g., a PID file could be in this directory, even though
396 use of this directory for something else than socket files is not
398 * fixed TLS library deinitialization after RSN pre-authentication not
399 to disable TLS library for normal authentication
400 * driver_wext: Remove null-termination from SSID length if the driver
401 used it; some Linux drivers do this and they were causing problems in
402 wpa_supplicant not finding matching configuration block. This change
403 would break a case where the SSID actually ends in '\0', but that is
404 not likely to happen in real use.
405 * fixed PMKSA cache processing not to trigger deauthentication if the
406 current PMKSA cache entry is replaced with a valid new entry
407 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
408 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
411 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
412 * added experimental STAKey handshake implementation for IEEE 802.11e
413 direct link setup (DLS); note: this is disabled by default in both
414 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
416 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
417 decrypt AT_ENCR_DATA attributes correctly
418 * fixed EAP-AKA to allow resynchronization within the same session
419 * made code closer to ANSI C89 standard to make it easier to port to
420 other C libraries and compilers
421 * started moving operating system or C library specific functions into
422 wrapper functions defined in os.h and implemented in os_*.c to make
424 * wpa_supplicant can now be built with Microsoft Visual C++
425 (e.g., with the freely available Toolkit 2003 version or Visual
426 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
427 example makefile for nmake
428 * added support for using Windows registry for command line parameters
429 (CONFIG_MAIN=main_winsvc) and configuration data
430 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
431 contents; this version can be run both as a Windows service and as a
432 normal application; 'wpasvc.exe app' to start as applicant,
433 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
434 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
436 * made it possible to link ndis_events.exe functionality into
437 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
438 * added better support for multiple control interface backends
439 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
440 * fixed PC/SC code to use correct length for GSM AUTH command buffer
441 and to not use pioRecvPci with SCardTransmit() calls; these were not
442 causing visible problems with pcsc-lite, but Windows Winscard.dll
443 refused the previously used parameters; this fixes EAP-SIM and
444 EAP-AKA authentication using SIM/USIM card under Windows
445 * added new event loop implementation for Windows using
446 WaitForMultipleObject() instead of select() in order to allow waiting
447 for non-socket objects; this can be selected with
448 CONFIG_ELOOP=eloop_win in .config
449 * added support for selecting l2_packet implementation in .config
450 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
451 winpcap, freebsd, none)
452 * added new l2_packet implementation for WinPcap
453 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
454 reduce latency in EAPOL receive processing from about 100 ms to about
456 * added support for EAP-FAST key derivation using other ciphers than
457 RC4-128-SHA for authentication and AES128-SHA for provisioning
458 * added support for configuring CA certificate as DER file and as a
460 * fixed private key configuration as configuration blob and added
461 support for using PKCS#12 as a blob
462 * tls_gnutls: added support for using PKCS#12 files; added support for
464 * added support for loading trusted CA certificates from Windows
465 certificate store: ca_cert="cert_store://<name>", where <name> is
466 likely CA (Intermediate CA certificates) or ROOT (root certificates)
467 * added C version of ndis_events.cpp and made it possible to build this
468 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
469 easily on cross-compilation builds
470 * added wpasvc.exe into Windows binary release; this is an alternative
471 version of wpa_supplicant.exe with configuration backend using
472 Windows registry and with the entry point designed to run as a
474 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
475 wpasvc.exe and removed this additional tool from the Windows binary
476 release since it is not needed anymore
477 * load winscard.dll functions dynamically when building with MinGW
478 since MinGW does not yet include winscard library
480 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
481 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
482 and WinPcap to receive frames sent to PAE group address
483 * disable EAP state machine when IEEE 802.1X authentication is not used
484 in order to get rid of bogus "EAP failed" messages
485 * fixed OpenSSL error reporting to go through all pending errors to
486 avoid confusing reports of old errors being reported at later point
488 * fixed configuration file updating to not write empty variables
489 (e.g., proto or key_mgmt) that the file parser would not accept
490 * fixed ADD_NETWORK ctrl_iface command to use the same default values
491 for variables as empty network definitions read from config file
493 * fixed EAP state machine to not discard EAP-Failure messages in many
494 cases (e.g., during TLS handshake)
495 * fixed a infinite loop in private key reading if the configured file
496 cannot be parsed successfully
497 * driver_madwifi: added support for madwifi-ng
498 * wpa_gui: do not display password/PSK field contents
499 * wpa_gui: added CA certificate configuration
500 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
501 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
502 the new AP is using different WPA/RSN IE
503 * use longer timeout for IEEE 802.11 association to avoid problems with
504 drivers that may take more than five second to associate
507 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
508 RSN IE, but WPA IE would match with wpa_supplicant configuration
509 * added support for named configuration blobs in order to avoid having
510 to use file system for external files (e.g., certificates);
511 variables can be set to "blob://<blob name>" instead of file path to
512 use a named blob; supported fields: pac_file, client_cert,
514 * fixed RSN pre-authentication (it was broken in the clean up of WPA
515 state machine interface in v0.4.5)
516 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
517 sure the driver configures broadcast decryption correctly
518 * added ca_path (and ca_path2) configuration variables that can be used
519 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
520 system-wide trusted CA list
521 * added support for starting wpa_supplicant without a configuration
522 file (-C argument must be used to set ctrl_interface parameter for
523 this case; in addition, -p argument can be used to provide
524 driver_param; these new arguments can also be used with a
525 configuration to override the values from the configuration)
526 * added global control interface that can be optionally used for adding
527 and removing network interfaces dynamically (-g command line argument
528 for both wpa_supplicant and wpa_cli) without having to restart
529 wpa_supplicant process
531 - try to save configuration whenever something is modified
532 - added WEP key configuration
533 - added possibility to edit the current network configuration
534 * driver_ndis: fixed driver polling not to increase frequency on each
535 received EAPOL frame due to incorrectly cancelled timeout
536 * added simple configuration file examples (in examples subdirectory)
537 * fixed driver_wext.c to filter wireless events based on ifindex to
538 avoid interfaces receiving events from other interfaces
539 * delay sending initial EAPOL-Start couple of seconds to speed up
540 authentication for the most common case of Authenticator starting
541 EAP authentication immediately after association
544 * added a workaround for clearing keys with ndiswrapper to allow
545 roaming from WPA enabled AP to plaintext one
546 * added docbook documentation (doc/docbook) that can be used to
547 generate, e.g., man pages
548 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
549 PF_PACKET in order to prepare for network devices that do not use
550 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
551 * use receipt of EAPOL-Key frame as a lower layer success indication
552 for EAP state machine to allow recovery from dropped EAP-Success
554 * cleaned up internal EAPOL frame processing by not including link
555 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
556 header is added only when transmitted the frame; this makes it easier
557 to use wpa_supplicant on link layers that use different header than
559 * updated EAP-PSK to use draft 9 by default since this can now be
560 tested with hostapd; removed support for draft 3, including
561 server_nai configuration option from network blocks
562 * driver_wired: add PAE address to the multicast address list in order
563 to be able to receive EAPOL frames with drivers that do not include
564 these multicast addresses by default
565 * driver_wext: add support for WE-19
566 * added support for multiple configuration backends (CONFIG_BACKEND
567 option); currently, only 'file' is supported (i.e., the format used
568 in wpa_supplicant.conf)
569 * added support for updating configuration ('wpa_cli save_config');
570 this is disabled by default and can be enabled with global
571 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
572 and wpa_gui to store the configuration changes in a permanent store
573 * added GET_NETWORK ctrl_iface command
574 (e.g., 'wpa_cli get_network 0 ssid')
577 * replaced OpenSSL patch for EAP-FAST support
578 (openssl-tls-extensions.patch) with a more generic and correct
579 patch (the new patch is not compatible with the previous one, so the
580 OpenSSL library will need to be patched with the new patch in order
581 to be able to build wpa_supplicant with EAP-FAST support)
582 * added support for using Windows certificate store (through CryptoAPI)
583 for client certificate and private key operations (EAP-TLS)
584 (see wpa_supplicant.conf for more information on how to configure
585 this with private_key)
586 * ported wpa_gui to Windows
587 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
588 built with the open source version of the Qt4 for Windows
589 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
590 with drivers that do not support WPA
591 * ndis_events: fixed Windows 2000 support
592 * added support for enabling/disabling networks from the list of all
593 configured networks ('wpa_cli enable_network <network id>' and
594 'wpa_cli disable_network <network id>')
595 * added support for adding and removing network from the current
596 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
597 <network id>'); added networks are disabled by default and they can
598 be enabled with enable_network command once the configuration is done
599 for the new network; note: configuration file is not yet updated, so
600 these new networks are lost when wpa_supplicant is restarted
601 * added support for setting network configuration parameters through
602 the control interface, for example:
603 wpa_cli set_network 0 ssid "\"my network\""
604 * fixed parsing of strings that include both " and # within double
605 quoted area (e.g., "start"#end")
606 * added EAP workaround for PEAP session resumption: allow outer,
607 i.e., not tunneled, EAP-Success to terminate session since; this can
608 be disabled with eap_workaround=0
609 (this was allowed for PEAPv1 before, but now it is also allowed for
610 PEAPv0 since at least one RADIUS authentication server seems to be
611 doing this for PEAPv0, too)
612 * wpa_gui: added preliminary support for adding new networks to the
613 wpa_supplicant configuration (double click on the scan results to
614 open network configuration)
617 * removed interface for external EAPOL/EAP supplicant (e.g.,
618 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
619 anymore and is unlikely to be used by anyone
620 * driver_ndis: fixed WinPcap 3.0 support
621 * fixed build with CONFIG_DNET_PCAP=y on Linux
622 * l2_packet: moved different implementations into separate files
626 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
627 (note: ipw2100-1.1.0 is likely to require an update to work with
629 * added support for using ap_scan=2 mode with multiple network blocks;
630 wpa_supplicant will go through the networks one by one until the
631 driver reports a successful association; this uses the same order for
632 networks as scan_ssid=1 scans, i.e., the priority field is ignored
633 and the network block order in the file is used instead
634 * fixed a potential issue in RSN pre-authentication ending up using
635 freed memory if pre-authentication times out
636 * added support for matching alternative subject name extensions of the
637 authentication server certificate; new configuration variables
638 altsubject_match and altsubject_match2
639 * driver_ndis: added support for IEEE 802.1X authentication with wired
641 * added support for querying private key password (EAP-TLS) through the
642 control interface (wpa_cli/wpa_gui) if one is not included in the
644 * driver_broadcom: fixed couple of memory leaks in scan result
646 * EAP-PAX is now registered as EAP type 46
647 * fixed EAP-PAX MAC calculation
648 * fixed EAP-PAX CK and ICK key derivation
649 * added support for using password with EAP-PAX (as an alternative to
650 entering key with eappsk); SHA-1 hash of the password will be used as
652 * added support for arbitrary driver interface parameters through the
653 configuration file with a new driver_param field; this adds a new
654 driver_ops function set_param()
655 * added possibility to override l2_packet module with driver interface
656 API (new send_eapol handler); this can be used to implement driver
657 specific TX/RX functions for EAPOL frames
658 * fixed ctrl_interface_group processing for the case where gid is
659 entered as a number, not group name
660 * driver_test: added support for testing hostapd with wpa_supplicant
661 by using test driver interface without any kernel drivers or network
665 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
666 packets to be encrypted; this was apparently broken by the changed
667 ioctl order in v0.4.0
668 * driver_madwifi: added preliminary support for compiling against 'BSD'
669 branch of madwifi CVS tree
670 * added support for EAP-MSCHAPv2 password retries within the same EAP
671 authentication session
672 * added support for password changes with EAP-MSCHAPv2 (used when the
673 password has expired)
674 * added support for reading additional certificates from PKCS#12 files
675 and adding them to the certificate chain
676 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
678 * fixed a possible double free in EAP-TTLS fast-reauthentication when
679 identity or password is entered through control interface
680 * display EAP Notification messages to user through control interface
681 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
682 * added GUI version of wpa_cli, wpa_gui; this is not build
683 automatically with 'make'; use 'make wpa_gui' to build (this requires
684 Qt development tools)
685 * added 'disconnect' command to control interface for setting
686 wpa_supplicant in state where it will not associate before
687 'reassociate' command has been used
688 * added support for selecting a network from the list of all configured
689 networks ('wpa_cli select_network <network id>'; this disabled all
690 other networks; to re-enable, 'wpa_cli select_network any')
691 * added support for getting scan results through control interface
692 * added EAP workaround for PEAPv1 session resumption: allow outer,
693 i.e., not tunneled, EAP-Success to terminate session since; this can
694 be disabled with eap_workaround=0
696 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
697 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
698 used to reduce the size of the wpa_supplicant considerably if
699 debugging code is not needed
700 * fixed EAPOL-Key validation to drop packets with invalid Key Data
701 Length; such frames could have crashed wpa_supplicant due to buffer
703 * added support for wired authentication (IEEE 802.1X on wired
704 Ethernet); driver interface 'wired'
705 * obsoleted set_wpa() handler in the driver interface API (it can be
706 replaced by moving enable/disable functionality into init()/deinit())
707 (calls to set_wpa() are still present for backwards compatibility,
708 but they may be removed in the future)
709 * driver_madwifi: fixed association in plaintext mode
710 * modified the EAP workaround that accepts EAP-Success with incorrect
711 Identifier to be even less strict about verification in order to
712 interoperate with some authentication servers
713 * added support for sending TLS alerts
714 * added support for 'any' SSID wildcard; if ssid is not configured or
715 is set to an empty string, any SSID will be accepted for non-WPA AP
716 * added support for asking PIN (for SIM) from frontends (e.g.,
717 wpa_cli); if a PIN is needed, but not included in the configuration
718 file, a control interface request is sent and EAP processing is
719 delayed until the PIN is available
720 * added support for using external devices (e.g., a smartcard) for
721 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
722 new wpa_supplicant.conf variables:
723 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
724 - network: engine, engine_id, key_id
725 * added experimental support for EAP-PAX
726 * added monitor mode for wpa_cli (-a<path to a program to run>) that
727 allows external commands (e.g., shell scripts) to be run based on
728 wpa_supplicant events, e.g., when authentication has been completed
729 and data connection is ready; other related wpa_cli arguments:
730 -B (run in background), -P (write PID file); wpa_supplicant has a new
731 command line argument (-W) that can be used to make it wait until a
732 control interface command is received in order to avoid missing
734 * added support for opportunistic WPA2 PMKSA key caching (disabled by
735 default, can be enabled with proactive_key_caching=1)
736 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
737 Authenticator rejects PMKSA caching attempt and the driver is not
738 using assoc_info events
739 * added -P<pid file> argument for wpa_supplicant to write the current
740 process id into a file
742 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
743 * added new phase1 option parameter, include_tls_length=1, to force
744 wpa_supplicant to add TLS Message Length field to all TLS messages
745 even if the packet is not fragmented; this may be needed with some
746 authentication servers
747 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
748 using drivers that take care of AP selection (e.g., when using
750 * fixed reprocessing of pending request after ctrl_iface requests for
751 identity/password/otp
752 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
753 EAP-PEAP and EAP-TTLS
754 * all drivers using driver_wext: set interface up and select Managed
755 mode when starting wpa_supplicant; set interface down when exiting
756 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
757 ipw2100 and ipw2200; please note that this also changed the
758 configuration variable in .config to CONFIG_DRIVER_IPW
761 * fixed a busy loop introduced in v0.3.5 for scan result processing
762 when no matching AP is found
765 * added a workaround for an interoperability issue with a Cisco AP
767 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
768 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
769 retransmission of dropped frames)
770 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
771 (e.g., segfault when processing EAPOL-Key frames)
772 * fixed EAP workaround and fast reauthentication configuration for
773 RSN pre-authentication; previously these were disabled and
774 pre-authentication would fail if the used authentication server
775 requires EAP workarounds
776 * added support for blacklisting APs that fail or timeout
777 authentication in ap_scan=1 mode so that all APs are tried in cases
778 where the ones with strongest signal level are failing authentication
779 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
780 authentication attempt
781 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
782 in the previous authentication (previously, only Phase 1 success was
786 * added preliminary support for IBSS (ad-hoc) mode configuration
787 (mode=1 in network block); this included a new key_mgmt mode
788 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
789 key management; see wpa_supplicant.conf for more details and an
790 example on how to configure this (note: this is currently implemented
791 only for driver_hostapd.c, but the changes should be trivial to add
792 in associate() handler for other drivers, too (assuming the driver
794 * added preliminary port for native Windows (i.e., no cygwin) using
798 * added optional support for GNU Readline and History Libraries for
799 wpa_cli (CONFIG_READLINE)
800 * cleaned up EAP state machine <-> method interface and number of
801 small problems with error case processing not terminating on
802 EAP-Failure but waiting for timeout
803 * added couple of workarounds for interoperability issues with a
804 Cisco AP when using WPA2
805 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
806 Note: This requires a patch for openssl to add support for TLS
807 extensions and number of workarounds for operations without
808 certificates. Proof of concept type of experimental patch is
809 included in openssl-tls-extensions.patch.
812 * fixed private key loading for cases where passphrase is not set
813 * fixed Windows/cygwin L2 packet handler freeing; previous version
814 could cause a segfault when RSN pre-authentication was completed
815 * added support for PMKSA caching with drivers that generate RSN IEs
816 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
817 but similar code can be easily added to driver_ndiswrapper.c once
818 ndiswrapper gets full support for RSN PMKSA caching
819 * improved recovery from PMKID mismatches by requesting full EAP
820 authentication in case of failed PMKSA caching attempt
821 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
822 (this requires that ndis_events is ran while wpa_supplicant is
824 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
825 * added support for driver interfaces to replace the interface name
826 based on driver/OS specific mapping, e.g., in case of driver_ndis,
827 this allows the beginning of the adapter description to be used as
829 * added support for CR+LF (Windows-style) line ends in configuration
831 * driver_ndis: enable radio before starting scanning, disable radio
833 * modified association event handler to set portEnabled = FALSE before
834 clearing port Valid in order to reset EAP state machine and avoid
835 problems with new authentication getting ignored because of state
836 machines ending up in AUTHENTICATED/SUCCESS state based on old
838 * added support for driver events to add PMKID candidates in order to
839 allow drivers to give priority to most likely roaming candidates
840 * driver_hostap: moved PrivacyInvoked configuration to associate()
841 function so that this will not be set for plaintext connections
842 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
843 interface can distinguish plaintext and IEEE 802.1X (no WPA)
845 * fixed static WEP key configuration to use broadcast/default type for
846 all keys (previously, the default TX key was configured as pairwise/
848 * driver_ndis: added legacy WPA capability detection for non-WPA2
850 * added support for setting static WEP keys for IEEE 802.1X without
851 dynamic WEP keying (eapol_flags=0)
854 * added support for reading PKCS#12 (PFX) files (as a replacement for
855 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
856 * fixed compilation with CONFIG_PCSC=y
857 * added new ap_scan mode, ap_scan=2, for drivers that take care of
858 association, but need to be configured with security policy and SSID,
859 e.g., ndiswrapper and NDIS driver; this mode should allow such
860 drivers to work with hidden SSIDs and optimized roaming; when
861 ap_scan=2 is used, only the first network block in the configuration
862 file is used and this configuration should have explicit security
863 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
864 group, proto variables
865 * added experimental port of wpa_supplicant for Windows
866 - driver_ndis.c driver interface (NDIS OIDs)
867 - currently, this requires cygwin and WinPcap
868 - small utility, win_if_list, can be used to get interface name
869 * control interface can now be removed at build time; add
870 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
871 * optional Xsupplicant interface can now be removed at build time;
872 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
873 * added auth_alg to driver interface associate() parameters to make it
874 easier for drivers to configure authentication algorithm as part of
877 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
878 * driver_broadcom: added new driver interface for Broadcom wl.o driver
879 (a generic driver for Broadcom IEEE 802.11a/g cards)
880 * wpa_cli: fixed parsing of -p <path> command line argument
881 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
882 ACK, not tunneled EAP-Success (of which only the first byte was
883 actually send due to a bug in previous code); this seems to
884 interoperate with most RADIUS servers that implements PEAPv1
885 * PEAPv1: added support for terminating PEAP authentication on tunneled
886 EAP-Success message; this can be configured by adding
887 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
888 (some RADIUS servers require this whereas others require a tunneled
890 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
891 the old label for key derivation; previously, the default was 1,
892 but it looks like most existing PEAPv1 implementations use the old
893 label which is thus more suitable default option
894 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
895 * fixed parsing of wep_tx_keyidx
896 * added support for configuring list of allowed Phase 2 EAP types
897 (for both EAP-PEAP and EAP-TTLS) instead of only one type
898 * added support for configuring IEEE 802.11 authentication algorithm
899 (auth_alg; mainly for using Shared Key authentication with static
901 * added support for EAP-AKA (with UMTS SIM)
902 * fixed couple of errors in PCSC handling that could have caused
903 random-looking errors for EAP-SIM
904 * added support for EAP-SIM pseudonyms and fast re-authentication
905 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
907 * added support for EAP-SIM with two challanges
908 (phase1="sim_min_num_chal=3" can be used to require three challenges)
909 * added support for configuring DH/DSA parameters for an ephemeral DH
910 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
911 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
912 and optional DH key exchange to achieve forward secracy with RSA keys
913 * added support for matching subject of the authentication server
914 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
915 configuration variables subject_match and subject_match2
916 * changed SSID configuration in driver_wext.c (used by many driver
917 interfaces) to use ssid_len+1 as the length for SSID since some Linux
919 * fixed couple of unaligned reads in scan result parsing to fix WPA
920 connection on some platforms (e.g., ARM)
921 * added driver interface for Intel ipw2100 driver
922 * added support for LEAP with WPA
923 * added support for larger scan results report (old limit was 4 kB of
924 data, i.e., about 35 or so APs) when using Linux wireless extensions
926 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
927 only if there is a PMKSA cache entry for the current AP
928 * fixed error handling for case where reading of scan results fails:
929 must schedule a new scan or wpa_supplicant will remain waiting
931 * changed debug output to remove shared password/key material by
932 default; all key information can be included with -K command line
933 argument to match the previous behavior
934 * added support for timestamping debug log messages (disabled by
935 default, can be enabled with -t command line argument)
936 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
937 if keys are not configured to be used; this fixes IEEE 802.1X mode
938 with drivers that use this information to configure whether Privacy
939 bit can be in Beacon frames (e.g., ndiswrapper)
940 * avoid clearing driver keys if no keys have been configured since last
941 key clear request; this seems to improve reliability of group key
942 handshake for ndiswrapper & NDIS driver which seems to be suffering
943 of some kind of timing issue when the keys are cleared again after
945 * changed driver interface API:
946 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
947 version is being used (now, this is set to 2; previously, it was
949 - pass pointer to private data structure to all calls
950 - the new API is not backwards compatible; all in-tree driver
951 interfaces has been converted to the new API
952 * added support for controlling multiple interfaces (radios) per
953 wpa_supplicant process; each interface needs to be listed on the
954 command line (-c, -i, -D arguments) with -N as a separator
955 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
956 * added a workaround for EAP servers that incorrectly use same Id for
957 sequential EAP packets
958 * changed libpcap/libdnet configuration to use .config variable,
959 CONFIG_DNET_PCAP, instead of requiring Makefile modification
960 * improved downgrade attack detection in IE verification of msg 3/4:
961 verify both WPA and RSN IEs, if present, not only the selected one;
962 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
963 Probe Response frame, and RSN is enabled in wpa_supplicant
965 * fixed WPA msg 3/4 processing to allow Key Data field contain other
966 IEs than just one WPA IE
967 * added support for FreeBSD and driver interface for the BSD net80211
968 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
969 required kernel mods have not yet been committed
970 * made EAP workarounds configurable; enabled by default, can be
971 disabled with network block option eap_workaround=0
973 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
974 * resolved couple of interoperability issues with EAP-PEAPv1 and
975 Phase 2 (inner EAP) fragment reassembly
976 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
977 AP is using non-zero key index for the unicast key and key index zero
978 for the broadcast key
979 * driver_hostap: fixed IEEE 802.1X WEP key updates and
980 re-authentication by allowing unencrypted EAPOL frames when not using
982 * added a new driver interface, 'wext', which uses only standard,
983 driver independent functionality in Linux wireless extensions;
984 currently, this can be used only for non-WPA IEEE 802.1X mode, but
985 eventually, this is to be extended to support full WPA/WPA2 once
986 Linux wireless extensions get support for this
987 * added support for mode in which the driver is responsible for AP
988 scanning and selection; this is disabled by default and can be
989 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
990 this mode can be used, e.g., with generic 'wext' driver interface to
991 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
992 supporting wireless extensions.
993 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
994 operation with an AP that does not include SSID in the Beacon frames)
995 * added support for new EAP authentication methods:
996 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
997 * added support for asking one-time-passwords from frontends (e.g.,
998 wpa_cli); this 'otp' command works otherwise like 'password' command,
999 but the password is used only once and the frontend will be asked for
1000 a new password whenever a request from authenticator requires a
1001 password; this can be used with both EAP-OTP and EAP-GTC
1002 * changed wpa_cli to automatically re-establish connection so that it
1003 does not need to be re-started when wpa_supplicant is terminated and
1005 * improved user data (identity/password/otp) requests through
1006 frontends: process pending EAPOL packets after getting new
1007 information so that full authentication does not need to be
1008 restarted; in addition, send pending requests again whenever a new
1009 frontend is attached
1010 * changed control frontends to use a new directory for socket files to
1011 make it easier for wpa_cli to automatically select between interfaces
1012 and to provide access control for the control interface;
1013 wpa_supplicant.conf: ctrl_interface is now a path
1014 (/var/run/wpa_supplicant is the recommended path) and
1015 ctrl_interface_group can be used to select which group gets access to
1016 the control interface;
1017 wpa_cli: by default, try to connect to the first interface available
1018 in /var/run/wpa_supplicant; this path can be overriden with -p option
1019 and an interface can be selected with -i option (i.e., in most common
1020 cases, wpa_cli does not need to get any arguments)
1021 * added support for LEAP
1022 * added driver interface for Linux ndiswrapper
1023 * added priority option for network blocks in the configuration file;
1024 this allows networks to be grouped based on priority (the scan
1025 results are searched for matches with network blocks in this order)
1028 * sort scan results to improve AP selection
1029 * fixed control interface socket removal for some error cases
1030 * improved scan requesting and authentication timeout
1031 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1033 * PEAP version can now be forced with phase1="peapver=<ver>"
1034 (mostly for testing; by default, the highest version supported by
1035 both the Supplicant and Authentication Server is selected
1037 * added support for madwifi driver (Atheros ar521x)
1038 * added a workaround for cases where AP sets Install Tx/Rx bit for
1039 WPA Group Key messages when pairwise keys are used (without this,
1040 the Group Key would be used for Tx and the AP would drop frames
1042 * added GSM SIM/USIM interface for GSM authentication algorithm for
1043 EAP-SIM; this requires pcsc-lite
1044 * added support for ATMEL AT76C5XXx driver
1045 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1046 does not include key data in the EAPOL-Key frame (i.e., part of
1047 EAP keying material is used as data encryption key)
1048 * added support for using plaintext and static WEP networks
1052 * added support for new EAP authentication methods:
1053 EAP-TTLS/EAP-MD5-Challenge
1055 EAP-TTLS/EAP-MSCHAPv2
1063 EAP-PEAP/MD5-Challenge
1065 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1066 * added support for anonymous identity (to be used when identity is
1067 sent in plaintext; real identity will be used within TLS protected
1068 tunnel (e.g., with EAP-TTLS)
1069 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1070 * added support for requesting identity and password information using
1071 control interface; in other words, the password for EAP-PEAP or
1072 EAP-TTLS does not need to be included in the configuration file since
1073 a frontand (e.g., wpa_cli) can ask it from the user
1074 * improved RSN pre-authentication to use a candidate list and process
1075 all candidates from each scan; not only one per scan
1076 * fixed RSN IE and WPA IE capabilities field parsing
1077 * ignore Tx bit in GTK IE when Pairwise keys are used
1078 * avoid making new scan requests during IEEE 802.1X negotiation
1079 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1080 with TLS support (this replaces the included implementation with
1081 library code to save about 8 kB since the library code is needed
1083 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1084 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1087 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1089 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1090 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1091 - EAP-MD5 (cannot be used with WPA-RADIUS)
1092 [draft-ietf-eap-rfc2284bis-09.txt]
1093 - EAP-TLS [RFC 2716]
1094 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1095 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1096 [draft-kamath-pppext-eap-mschapv2-00.txt]
1097 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1098 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1099 - new configuration file options: eap, identity, password, ca_cert,
1100 client_cert, privatekey, private_key_passwd
1101 - Xsupplicant is not required anymore, but it can be used by
1102 disabling the internal IEEE 802.1X Supplicant with -e command line
1104 - this code is not included in the default build; Makefile need to
1105 be edited for this (uncomment lines for selected functionality)
1106 - EAP-TLS and EAP-PEAP require openssl libraries
1107 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1108 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1109 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1110 EAPOL-Key frames instead of WPA key handshakes)
1111 * added support for IEEE 802.11i/RSN (WPA2)
1112 - improved PTK Key Handshake
1113 - PMKSA caching, pre-authentication
1114 * fixed wpa_supplicant to ignore possible extra data after WPA
1115 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1116 TPTK' error from message 3 of 4-Way Handshake in case the AP
1117 includes extra data after the EAPOL-Key)
1118 * added interface for external programs (frontends) to control
1120 - CLI example (wpa_cli) with interactive mode and command line
1122 - replaced SIGUSR1 status/statistics with the new control interface
1123 * made some feature compile time configurable
1124 - .config file for make
1125 - driver interfaces (hostap, hermes, ..)
1126 - EAPOL/EAP functions
1129 * Initial version of wpa_supplicant
