1 ChangeLog for wpa_supplicant
4 * added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
5 (can be used to simulate test SIM/USIM card with a known private key;
6 enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
7 and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
8 * added a new network configuration option, wpa_ptk_rekey, that can be
9 used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
10 against TKIP deficiencies
11 * added an optional mitigation mechanism for certain attacks against
12 TKIP by delaying Michael MIC error reports by a random amount of time
13 between 0 and 60 seconds; this can be enabled with a build option
14 CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
15 * fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
17 * updated OpenSSL code for EAP-FAST to use an updated version of the
18 session ticket overriding API that was included into the upstream
19 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
20 needed with that version anymore)
21 * updated userspace MLME instructions to match with the current Linux
22 mac80211 implementation; please also note that this can only be used
23 with driver_nl80211.c (the old code from driver_wext.c was removed)
24 * added support (Linux only) for RoboSwitch chipsets (often found in
25 consumer grade routers); driver interface 'roboswitch'
26 * fixed canceling of PMKSA caching when using drivers that generate
27 RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
31 * added support for SHA-256 as X.509 certificate digest when using the
32 internal X.509/TLSv1 implementation
33 * updated management frame protection to use IEEE 802.11w/D6.0
34 * added support for using SHA256-based stronger key derivation for WPA2
36 * fixed FT (IEEE 802.11r) authentication after a failed association to
38 * added support for configuring Phase 2 (inner/tunneled) authentication
39 method with wpa_gui-qt4
42 * added support for EAP Sequences in EAP-FAST Phase 2
43 * added support for using TNC with EAP-FAST
44 * added driver_ps3 for the PS3 Linux wireless driver
45 * added support for optional cryptobinding with PEAPv0
46 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
47 allow fallback to full handshake if server rejects PAC-Opaque
48 * added fragmentation support for EAP-TNC
49 * added support for parsing PKCS #8 formatted private keys into the
50 internal TLS implementation (both PKCS #1 RSA key and PKCS #8
51 encapsulated RSA key can now be used)
52 * added option of using faster, but larger, routines in the internal
53 LibTomMath (for internal TLS implementation) to speed up DH and RSA
54 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
55 * fixed race condition between disassociation event and group key
56 handshake to avoid getting stuck in incorrect state [Bug 261]
57 * fixed opportunistic key caching (proactive_key_caching)
60 * removed 'nai' and 'eappsk' network configuration variables that were
61 previously used for configuring user identity and key for EAP-PSK,
62 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
63 replacement for 'nai' (if old configuration used a separate
64 'identity' value, that would now be configured as
65 'anonymous_identity'). 'password' field is now used as the
66 replacement for 'eappsk' (it can also be set using hexstring to
67 present random binary data)
68 * removed '-w' command line parameter (wait for interface to be added,
69 if needed); cleaner way of handling this functionality is to use an
70 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
71 when an interface is added
72 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
73 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
74 indicating when new scan results become available
75 * added new ctrl_iface command, BSS, to allow scan results to be
76 fetched without hitting the message size limits (this command
77 can be used to iterate through the scan results one BSS at the time)
78 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
79 attributes in EAP-SIM Start/Response when using fast reauthentication
80 * fixed EAPOL not to end up in infinite loop when processing dynamic
81 WEP keys with IEEE 802.1X
82 * fixed problems in getting NDIS events from WMI on Windows 2000
85 * added support for Makefile builds to include debug-log-to-a-file
86 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
87 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
88 lengths properly to avoid potential crash caused by invalid messages
89 * added data structure for storing allocated buffers (struct wpabuf);
90 this does not affect wpa_supplicant usage, but many of the APIs
91 changed and various interfaces (e.g., EAP) is not compatible with old
93 * added support for protecting EAP-AKA/Identity messages with
94 AT_CHECKCODE (optional feature in RFC 4187)
95 * added support for protected result indication with AT_RESULT_IND for
96 EAP-SIM and EAP-AKA (phase1="result_ind=1")
97 * added driver_wext workaround for race condition between scanning and
98 association with drivers that take very long time to scan all
99 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
100 using a longer hardcoded timeout for the scan if the driver supports
101 notifications for scan completion (SIOCGIWSCAN event); this helps,
102 e.g., in cases where wpa_supplicant and madwifi driver ended up in
103 loop where the driver did not even try to associate
104 * stop EAPOL timer tick when no timers are in use in order to reduce
105 power consumption (no need to wake up the process once per second)
107 * added support for privilege separation (run only minimal part of
108 wpa_supplicant functionality as root and rest as unprivileged,
109 non-root process); see 'Privilege separation' in README for details;
110 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
112 * changed scan results data structure to include all information
113 elements to make it easier to support new IEs; old get_scan_result()
114 driver_ops is still supported for backwards compatibility (results
115 are converted internally to the new format), but all drivers should
116 start using the new get_scan_results2() to make them more likely to
117 work with new features
118 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
119 application, i.e., it does not require Qt3Support anymore; Windows
120 binary of wpa_gui.exe is now from this directory and only requires
121 QtCore4.dll and QtGui4.dll libraries
122 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
123 available as a separate package to make wpa_gui installation easier:
124 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
125 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
126 only shared key/password authentication is supported in this version
129 * added support for configuring password as NtPasswordHash
130 (16-byte MD4 hash of password) in hash:<32 hex digits> format
131 * added support for fallback from abbreviated TLS handshake to
132 full handshake when using EAP-FAST (e.g., due to an expired
134 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
135 draft (draft-ietf-emu-eap-gpsk-07.txt)
136 * added support for drivers that take care of RSN 4-way handshake
137 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
138 WPA_ALG_PMK in set_key)
139 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
140 .config); this version supports only ap_scan=2 mode and allow the
141 driver to take care of the 4-way handshake
142 * fixed a buffer overflow in parsing TSF from scan results when using
143 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
145 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
146 * fixed an integer overflow issue in the ASN.1 parser used by the
147 (experimental) internal TLS implementation to avoid a potential
149 * fixed a race condition with -W option (wait for a control interface
150 monitor before starting) that could have caused the first messages to
152 * added support for processing TNCC-TNCS-Messages to report
153 recommendation (allow/none/isolate) when using TNC [Bug 243]
156 * added network configuration parameter 'frequency' for setting
157 initial channel for IBSS (adhoc) networks
158 * added experimental IEEE 802.11r/D6.0 support
159 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
160 * updated EAP-PSK to use the IANA-allocated EAP type 47
161 * fixed EAP-PAX key derivation
162 * fixed EAP-PSK bit ordering of the Flags field
163 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
164 tunnelled identity request (previously, the identifier from the outer
165 method was used, not the tunnelled identifier which could be
167 * added support for fragmentation of outer TLS packets during Phase 2
168 of EAP-PEAP/TTLS/FAST
169 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
170 * added support for EAP-FAST authentication with inner methods that
171 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
172 for PAC provisioning)
173 * added support for authenticated EAP-FAST provisioning
174 * added support for configuring maximum number of EAP-FAST PACs to
175 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
176 * added support for storing EAP-FAST PACs in binary format
177 (fast_pac_format=binary in phase1 string)
178 * fixed dbus ctrl_iface to validate message interface before
179 dispatching to avoid a possible segfault [Bug 190]
180 * fixed PeerKey key derivation to use the correct PRF label
181 * updated Windows binary build to link against OpenSSL 0.9.8d and
182 added support for EAP-FAST
183 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
184 draft (draft-ietf-emu-eap-gpsk-04.txt)
185 * fixed EAP-AKA Notification processing to allow Notification to be
186 processed after AKA Challenge response has been sent
187 * updated to use IEEE 802.11w/D2.0 for management frame protection
189 * fixed EAP-TTLS implementation not to crash on use of freed memory
190 if TLS library initialization fails
191 * added support for EAP-TNC (Trusted Network Connect)
192 (this version implements the EAP-TNC method and EAP-TTLS changes
193 needed to run two methods in sequence (IF-T) and the IF-IMC and
194 IF-TNCCS interfaces from TNCC)
197 * added experimental, integrated TLSv1 client implementation with the
198 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
199 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
200 .config); this can be useful, e.g., if the target system does not
201 have a suitable TLS library and a minimal code size is required
202 (total size of this internal TLS/crypto code is bit under 50 kB on
203 x86 and the crypto code is shared by rest of the supplicant so some
204 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
205 * removed STAKey handshake since PeerKey handshake has replaced it in
206 IEEE 802.11ma and there are no known deployments of STAKey
207 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
208 draft (draft-ietf-emu-eap-gpsk-01.txt)
209 * added preliminary implementation of IEEE 802.11w/D1.0 (management
211 (Note: this requires driver support to work properly.)
212 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
213 * fixed Windows named pipes ctrl_iface to not stop listening for
214 commands if client program opens a named pipe and closes it
215 immediately without sending a command
216 * fixed USIM PIN status determination for the case that PIN is not
217 needed (this allows EAP-AKA to be used with USIM cards that do not
219 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
220 be used with cards that do not support file selection based on
222 * added support for matching the subjectAltName of the authentication
223 server certificate against multiple name components (e.g.,
224 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
225 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
226 affects IEEE 802.1X with dynamic WEP keys)
227 * changed ctrl_iface network configuration 'get' operations to not
228 return password/key material; if these fields are requested, "*"
229 will be returned if the password/key is set, but the value of the
230 parameter is not exposed
233 * added support for building Windows version with UNICODE defined
234 (wide-char functions)
235 * driver_ndis: fixed static WEP configuration to avoid race condition
236 issues with some NDIS drivers between association and setting WEP
238 * driver_ndis: added validation for IELength value in scan results to
239 avoid crashes when using buggy NDIS drivers [Bug 165]
240 * fixed Release|Win32 target in the Visual Studio project files
241 (previously, only Debug|Win32 target was set properly)
242 * changed control interface API call wpa_ctrl_pending() to allow it to
243 return -1 on error (e.g., connection lost); control interface clients
244 will need to make sure that they verify that the value is indeed >0
245 when determining whether there are pending messages
246 * added an alternative control interface backend for Windows targets:
247 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
248 control interface mechanism for Windows builds (previously, UDP to
250 * changed ctrl_interface configuration for UNIX domain sockets:
251 - deprecated ctrl_interface_group variable (it may be removed in
253 - allow both directory and group be configured with ctrl_interface
254 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
255 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
256 case when group is not changed
257 * added support for controlling more than one interface per process in
259 * added a workaround for a case where the AP is using unknown address
260 (e.g., MAC address of the wired interface) as the source address for
261 EAPOL-Key frames; previously, that source address was used as the
262 destination for EAPOL-Key frames and in key derivation; now, BSSID is
263 used even if the source address does not match with it
264 (this resolves an interoperability issue with Thomson SpeedTouch 580)
265 * added a workaround for UDP-based control interface (which was used in
266 Windows builds before this release) to prevent packets with forged
267 addresses from being accepted as local control requests
268 * removed ndis_events.cpp and possibility of using external
269 ndis_events.exe; C version (ndis_events.c) is fully functional and
270 there is no desire to maintain two separate versions of this
272 * ndis_events: Changed NDIS event notification design to use WMI to
273 learn the adapter description through Win32_PnPEntity class; this
274 should fix some cases where the adapter name was not recognized
275 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
277 * fixed selection of the first network in ap_scan=2 mode; previously,
278 wpa_supplicant could get stuck in SCANNING state when only the first
279 network for enabled (e.g., after 'wpa_cli select_network 0')
280 * winsvc: added support for configuring ctrl_interface parameters in
281 registry (ctrl_interface string value in
282 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
283 required to enable control interface (previously, this was hardcoded
285 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
286 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
289 * fixed build with CONFIG_STAKEY=y [Bug 143]
290 * added support for doing MLME (IEEE 802.11 management frame
291 processing) in wpa_supplicant when using Devicescape IEEE 802.11
292 stack (wireless-dev.git tree)
293 * added a new network block configuration option, fragment_size, to
294 configure the maximum EAP fragment size
295 * driver_ndis: Disable WZC automatically for the selected interface to
296 avoid conflicts with two programs trying to control the radio; WZC
297 will be re-enabled (if it was enabled originally) when wpa_supplicant
299 * added an experimental TLSv1 client implementation
300 (CONFIG_TLS=internal) that can be used instead of an external TLS
301 library, e.g., to reduce total size requirement on systems that do
302 not include any TLS library by default (this is not yet complete;
303 basic functionality is there, but certificate validation is not yet
305 * added PeerKey handshake implementation for IEEE 802.11e
306 direct link setup (DLS) to replace STAKey handshake
307 * fixed WPA PSK update through ctrl_iface for the case where the old
308 PSK was derived from an ASCII passphrase and the new PSK is set as
309 a raw PSK (hex string)
310 * added new configuration option for identifying which network block
311 was used (id_str in wpa_supplicant.conf; included on
312 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
313 variable in wpa_cli action scripts; in addition WPA_ID variable is
314 set to the current unique identifier that wpa_supplicant assigned
315 automatically for the network and that can be used with
316 GET_NETWORK/SET_NETWORK ctrl_iface commands)
317 * wpa_cli action script is now called only when the connect/disconnect
318 status changes or when associating with a different network
319 * fixed configuration parser not to remove CCMP from group cipher list
320 if WPA-None (adhoc) is used (pairwise=NONE in that case)
321 * fixed integrated NDIS events processing not to hang the process due
322 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
323 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
324 draft-clancy-emu-eap-shared-secret-00.txt)
325 * added Microsoft Visual Studio 2005 solution and project files for
326 build wpa_supplicant for Windows (see vs2005 subdirectory)
327 * eloop_win: fixed unregistration of Windows events
328 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
329 at the end of RSN pre-authentication and added unregistration of
330 a Windows event to avoid getting eloop_win stuck with an invalid
332 * driver_ndis: added support for selecting AP based on BSSID
333 * added new environmental variable for wpa_cli action scripts:
334 WPA_CTRL_DIR is the current control interface directory
335 * driver_ndis: added support for using NDISUIO instead of WinPcap for
336 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
337 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
338 wpa_supplicant without requiring WinPcap; note that using NDISUIO
339 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
340 only one application to open the device
341 * changed NDIS driver naming to only include device GUID, e.g.,
342 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
343 specific \Device\NPF_ prefix before the GUID; the prefix is still
344 allowed for backwards compatibility, but it is not required anymore
345 when specifying the interface
346 * driver_ndis: re-initialize driver interface is the adapter is removed
347 and re-inserted [Bug 159]
348 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
349 big endian hosts [Bug 146]
352 * fixed EAP-GTC response to include correct user identity when run as
353 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
354 * driver_ndis: Fixed encryption mode configuration for unencrypted
355 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
356 refused to associate with open networks) [Bug 106]
357 * driver_ndis: use BSSID OID polling to detect when IBSS network is
358 formed even when ndis_events code is included since some NDIS drivers
359 do not generate media connect events in IBSS mode
360 * config_winreg: allow global ctrl_interface parameter to be configured
362 * config_winreg: added support for saving configuration data into
364 * added support for controlling network device operational state
365 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
366 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
367 that can use this information)
368 * driver_wext: added support for WE-21 change to SSID configuration
369 * driver_wext: fixed privacy configuration for static WEP keys mode
371 * added an optional driver_ops callback for MLME-SETPROTECTION.request
373 * added support for EAP-SAKE (no EAP method number allocated yet, so
374 this is using the same experimental type 255 as EAP-PSK)
375 * added support for dynamically loading EAP methods (.so files) instead
376 of requiring them to be statically linked in; this is disabled by
377 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
381 * do not try to use USIM APDUs when initializing PC/SC for SIM card
382 access for a network that has not enabled EAP-AKA
383 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
384 v0.5.1 due to the new support for expanded EAP types)
385 * added support for generating EAP Expanded Nak
386 * try to fetch scan results once before requesting new scan when
387 starting up in ap_scan=1 mode (this can speed up initial association
388 a lot with, e.g., madwifi-ng driver)
389 * added support for receiving EAPOL frames from a Linux bridge
390 interface (-bbr0 on command line)
391 * fixed EAPOL re-authentication for sessions that used PMKSA caching
392 * changed EAP method registration to use a dynamic list of methods
393 instead of a static list generated at build time
394 * fixed PMKSA cache deinitialization not to use freed memory when
395 removing PMKSA entries
396 * fixed a memory leak in EAP-TTLS re-authentication
397 * reject WPA/WPA2 message 3/4 if it does not include any valid
399 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
400 if the driver does not support SIOCSIWAUTH
403 * driver_test: added better support for multiple APs and STAs by using
404 a directory with sockets that include MAC address for each device in
405 the name (driver_param=test_dir=/tmp/test)
406 * added support for EAP expanded type (vendor specific EAP methods)
407 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
408 option can be changed if needed
409 * wpa_cli/wpa_gui: skip non-socket files in control directory when
410 using UNIX domain sockets; this avoids selecting an incorrect
411 interface (e.g., a PID file could be in this directory, even though
412 use of this directory for something else than socket files is not
414 * fixed TLS library deinitialization after RSN pre-authentication not
415 to disable TLS library for normal authentication
416 * driver_wext: Remove null-termination from SSID length if the driver
417 used it; some Linux drivers do this and they were causing problems in
418 wpa_supplicant not finding matching configuration block. This change
419 would break a case where the SSID actually ends in '\0', but that is
420 not likely to happen in real use.
421 * fixed PMKSA cache processing not to trigger deauthentication if the
422 current PMKSA cache entry is replaced with a valid new entry
423 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
424 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
427 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
428 * added experimental STAKey handshake implementation for IEEE 802.11e
429 direct link setup (DLS); note: this is disabled by default in both
430 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
432 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
433 decrypt AT_ENCR_DATA attributes correctly
434 * fixed EAP-AKA to allow resynchronization within the same session
435 * made code closer to ANSI C89 standard to make it easier to port to
436 other C libraries and compilers
437 * started moving operating system or C library specific functions into
438 wrapper functions defined in os.h and implemented in os_*.c to make
440 * wpa_supplicant can now be built with Microsoft Visual C++
441 (e.g., with the freely available Toolkit 2003 version or Visual
442 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
443 example makefile for nmake
444 * added support for using Windows registry for command line parameters
445 (CONFIG_MAIN=main_winsvc) and configuration data
446 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
447 contents; this version can be run both as a Windows service and as a
448 normal application; 'wpasvc.exe app' to start as applicant,
449 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
450 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
452 * made it possible to link ndis_events.exe functionality into
453 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
454 * added better support for multiple control interface backends
455 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
456 * fixed PC/SC code to use correct length for GSM AUTH command buffer
457 and to not use pioRecvPci with SCardTransmit() calls; these were not
458 causing visible problems with pcsc-lite, but Windows Winscard.dll
459 refused the previously used parameters; this fixes EAP-SIM and
460 EAP-AKA authentication using SIM/USIM card under Windows
461 * added new event loop implementation for Windows using
462 WaitForMultipleObject() instead of select() in order to allow waiting
463 for non-socket objects; this can be selected with
464 CONFIG_ELOOP=eloop_win in .config
465 * added support for selecting l2_packet implementation in .config
466 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
467 winpcap, freebsd, none)
468 * added new l2_packet implementation for WinPcap
469 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
470 reduce latency in EAPOL receive processing from about 100 ms to about
472 * added support for EAP-FAST key derivation using other ciphers than
473 RC4-128-SHA for authentication and AES128-SHA for provisioning
474 * added support for configuring CA certificate as DER file and as a
476 * fixed private key configuration as configuration blob and added
477 support for using PKCS#12 as a blob
478 * tls_gnutls: added support for using PKCS#12 files; added support for
480 * added support for loading trusted CA certificates from Windows
481 certificate store: ca_cert="cert_store://<name>", where <name> is
482 likely CA (Intermediate CA certificates) or ROOT (root certificates)
483 * added C version of ndis_events.cpp and made it possible to build this
484 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
485 easily on cross-compilation builds
486 * added wpasvc.exe into Windows binary release; this is an alternative
487 version of wpa_supplicant.exe with configuration backend using
488 Windows registry and with the entry point designed to run as a
490 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
491 wpasvc.exe and removed this additional tool from the Windows binary
492 release since it is not needed anymore
493 * load winscard.dll functions dynamically when building with MinGW
494 since MinGW does not yet include winscard library
496 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
497 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
498 and WinPcap to receive frames sent to PAE group address
499 * disable EAP state machine when IEEE 802.1X authentication is not used
500 in order to get rid of bogus "EAP failed" messages
501 * fixed OpenSSL error reporting to go through all pending errors to
502 avoid confusing reports of old errors being reported at later point
504 * fixed configuration file updating to not write empty variables
505 (e.g., proto or key_mgmt) that the file parser would not accept
506 * fixed ADD_NETWORK ctrl_iface command to use the same default values
507 for variables as empty network definitions read from config file
509 * fixed EAP state machine to not discard EAP-Failure messages in many
510 cases (e.g., during TLS handshake)
511 * fixed a infinite loop in private key reading if the configured file
512 cannot be parsed successfully
513 * driver_madwifi: added support for madwifi-ng
514 * wpa_gui: do not display password/PSK field contents
515 * wpa_gui: added CA certificate configuration
516 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
517 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
518 the new AP is using different WPA/RSN IE
519 * use longer timeout for IEEE 802.11 association to avoid problems with
520 drivers that may take more than five second to associate
523 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
524 RSN IE, but WPA IE would match with wpa_supplicant configuration
525 * added support for named configuration blobs in order to avoid having
526 to use file system for external files (e.g., certificates);
527 variables can be set to "blob://<blob name>" instead of file path to
528 use a named blob; supported fields: pac_file, client_cert,
530 * fixed RSN pre-authentication (it was broken in the clean up of WPA
531 state machine interface in v0.4.5)
532 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
533 sure the driver configures broadcast decryption correctly
534 * added ca_path (and ca_path2) configuration variables that can be used
535 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
536 system-wide trusted CA list
537 * added support for starting wpa_supplicant without a configuration
538 file (-C argument must be used to set ctrl_interface parameter for
539 this case; in addition, -p argument can be used to provide
540 driver_param; these new arguments can also be used with a
541 configuration to override the values from the configuration)
542 * added global control interface that can be optionally used for adding
543 and removing network interfaces dynamically (-g command line argument
544 for both wpa_supplicant and wpa_cli) without having to restart
545 wpa_supplicant process
547 - try to save configuration whenever something is modified
548 - added WEP key configuration
549 - added possibility to edit the current network configuration
550 * driver_ndis: fixed driver polling not to increase frequency on each
551 received EAPOL frame due to incorrectly cancelled timeout
552 * added simple configuration file examples (in examples subdirectory)
553 * fixed driver_wext.c to filter wireless events based on ifindex to
554 avoid interfaces receiving events from other interfaces
555 * delay sending initial EAPOL-Start couple of seconds to speed up
556 authentication for the most common case of Authenticator starting
557 EAP authentication immediately after association
560 * added a workaround for clearing keys with ndiswrapper to allow
561 roaming from WPA enabled AP to plaintext one
562 * added docbook documentation (doc/docbook) that can be used to
563 generate, e.g., man pages
564 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
565 PF_PACKET in order to prepare for network devices that do not use
566 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
567 * use receipt of EAPOL-Key frame as a lower layer success indication
568 for EAP state machine to allow recovery from dropped EAP-Success
570 * cleaned up internal EAPOL frame processing by not including link
571 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
572 header is added only when transmitted the frame; this makes it easier
573 to use wpa_supplicant on link layers that use different header than
575 * updated EAP-PSK to use draft 9 by default since this can now be
576 tested with hostapd; removed support for draft 3, including
577 server_nai configuration option from network blocks
578 * driver_wired: add PAE address to the multicast address list in order
579 to be able to receive EAPOL frames with drivers that do not include
580 these multicast addresses by default
581 * driver_wext: add support for WE-19
582 * added support for multiple configuration backends (CONFIG_BACKEND
583 option); currently, only 'file' is supported (i.e., the format used
584 in wpa_supplicant.conf)
585 * added support for updating configuration ('wpa_cli save_config');
586 this is disabled by default and can be enabled with global
587 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
588 and wpa_gui to store the configuration changes in a permanent store
589 * added GET_NETWORK ctrl_iface command
590 (e.g., 'wpa_cli get_network 0 ssid')
593 * replaced OpenSSL patch for EAP-FAST support
594 (openssl-tls-extensions.patch) with a more generic and correct
595 patch (the new patch is not compatible with the previous one, so the
596 OpenSSL library will need to be patched with the new patch in order
597 to be able to build wpa_supplicant with EAP-FAST support)
598 * added support for using Windows certificate store (through CryptoAPI)
599 for client certificate and private key operations (EAP-TLS)
600 (see wpa_supplicant.conf for more information on how to configure
601 this with private_key)
602 * ported wpa_gui to Windows
603 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
604 built with the open source version of the Qt4 for Windows
605 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
606 with drivers that do not support WPA
607 * ndis_events: fixed Windows 2000 support
608 * added support for enabling/disabling networks from the list of all
609 configured networks ('wpa_cli enable_network <network id>' and
610 'wpa_cli disable_network <network id>')
611 * added support for adding and removing network from the current
612 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
613 <network id>'); added networks are disabled by default and they can
614 be enabled with enable_network command once the configuration is done
615 for the new network; note: configuration file is not yet updated, so
616 these new networks are lost when wpa_supplicant is restarted
617 * added support for setting network configuration parameters through
618 the control interface, for example:
619 wpa_cli set_network 0 ssid "\"my network\""
620 * fixed parsing of strings that include both " and # within double
621 quoted area (e.g., "start"#end")
622 * added EAP workaround for PEAP session resumption: allow outer,
623 i.e., not tunneled, EAP-Success to terminate session since; this can
624 be disabled with eap_workaround=0
625 (this was allowed for PEAPv1 before, but now it is also allowed for
626 PEAPv0 since at least one RADIUS authentication server seems to be
627 doing this for PEAPv0, too)
628 * wpa_gui: added preliminary support for adding new networks to the
629 wpa_supplicant configuration (double click on the scan results to
630 open network configuration)
633 * removed interface for external EAPOL/EAP supplicant (e.g.,
634 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
635 anymore and is unlikely to be used by anyone
636 * driver_ndis: fixed WinPcap 3.0 support
637 * fixed build with CONFIG_DNET_PCAP=y on Linux
638 * l2_packet: moved different implementations into separate files
642 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
643 (note: ipw2100-1.1.0 is likely to require an update to work with
645 * added support for using ap_scan=2 mode with multiple network blocks;
646 wpa_supplicant will go through the networks one by one until the
647 driver reports a successful association; this uses the same order for
648 networks as scan_ssid=1 scans, i.e., the priority field is ignored
649 and the network block order in the file is used instead
650 * fixed a potential issue in RSN pre-authentication ending up using
651 freed memory if pre-authentication times out
652 * added support for matching alternative subject name extensions of the
653 authentication server certificate; new configuration variables
654 altsubject_match and altsubject_match2
655 * driver_ndis: added support for IEEE 802.1X authentication with wired
657 * added support for querying private key password (EAP-TLS) through the
658 control interface (wpa_cli/wpa_gui) if one is not included in the
660 * driver_broadcom: fixed couple of memory leaks in scan result
662 * EAP-PAX is now registered as EAP type 46
663 * fixed EAP-PAX MAC calculation
664 * fixed EAP-PAX CK and ICK key derivation
665 * added support for using password with EAP-PAX (as an alternative to
666 entering key with eappsk); SHA-1 hash of the password will be used as
668 * added support for arbitrary driver interface parameters through the
669 configuration file with a new driver_param field; this adds a new
670 driver_ops function set_param()
671 * added possibility to override l2_packet module with driver interface
672 API (new send_eapol handler); this can be used to implement driver
673 specific TX/RX functions for EAPOL frames
674 * fixed ctrl_interface_group processing for the case where gid is
675 entered as a number, not group name
676 * driver_test: added support for testing hostapd with wpa_supplicant
677 by using test driver interface without any kernel drivers or network
681 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
682 packets to be encrypted; this was apparently broken by the changed
683 ioctl order in v0.4.0
684 * driver_madwifi: added preliminary support for compiling against 'BSD'
685 branch of madwifi CVS tree
686 * added support for EAP-MSCHAPv2 password retries within the same EAP
687 authentication session
688 * added support for password changes with EAP-MSCHAPv2 (used when the
689 password has expired)
690 * added support for reading additional certificates from PKCS#12 files
691 and adding them to the certificate chain
692 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
694 * fixed a possible double free in EAP-TTLS fast-reauthentication when
695 identity or password is entered through control interface
696 * display EAP Notification messages to user through control interface
697 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
698 * added GUI version of wpa_cli, wpa_gui; this is not build
699 automatically with 'make'; use 'make wpa_gui' to build (this requires
700 Qt development tools)
701 * added 'disconnect' command to control interface for setting
702 wpa_supplicant in state where it will not associate before
703 'reassociate' command has been used
704 * added support for selecting a network from the list of all configured
705 networks ('wpa_cli select_network <network id>'; this disabled all
706 other networks; to re-enable, 'wpa_cli select_network any')
707 * added support for getting scan results through control interface
708 * added EAP workaround for PEAPv1 session resumption: allow outer,
709 i.e., not tunneled, EAP-Success to terminate session since; this can
710 be disabled with eap_workaround=0
712 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
713 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
714 used to reduce the size of the wpa_supplicant considerably if
715 debugging code is not needed
716 * fixed EAPOL-Key validation to drop packets with invalid Key Data
717 Length; such frames could have crashed wpa_supplicant due to buffer
719 * added support for wired authentication (IEEE 802.1X on wired
720 Ethernet); driver interface 'wired'
721 * obsoleted set_wpa() handler in the driver interface API (it can be
722 replaced by moving enable/disable functionality into init()/deinit())
723 (calls to set_wpa() are still present for backwards compatibility,
724 but they may be removed in the future)
725 * driver_madwifi: fixed association in plaintext mode
726 * modified the EAP workaround that accepts EAP-Success with incorrect
727 Identifier to be even less strict about verification in order to
728 interoperate with some authentication servers
729 * added support for sending TLS alerts
730 * added support for 'any' SSID wildcard; if ssid is not configured or
731 is set to an empty string, any SSID will be accepted for non-WPA AP
732 * added support for asking PIN (for SIM) from frontends (e.g.,
733 wpa_cli); if a PIN is needed, but not included in the configuration
734 file, a control interface request is sent and EAP processing is
735 delayed until the PIN is available
736 * added support for using external devices (e.g., a smartcard) for
737 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
738 new wpa_supplicant.conf variables:
739 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
740 - network: engine, engine_id, key_id
741 * added experimental support for EAP-PAX
742 * added monitor mode for wpa_cli (-a<path to a program to run>) that
743 allows external commands (e.g., shell scripts) to be run based on
744 wpa_supplicant events, e.g., when authentication has been completed
745 and data connection is ready; other related wpa_cli arguments:
746 -B (run in background), -P (write PID file); wpa_supplicant has a new
747 command line argument (-W) that can be used to make it wait until a
748 control interface command is received in order to avoid missing
750 * added support for opportunistic WPA2 PMKSA key caching (disabled by
751 default, can be enabled with proactive_key_caching=1)
752 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
753 Authenticator rejects PMKSA caching attempt and the driver is not
754 using assoc_info events
755 * added -P<pid file> argument for wpa_supplicant to write the current
756 process id into a file
758 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
759 * added new phase1 option parameter, include_tls_length=1, to force
760 wpa_supplicant to add TLS Message Length field to all TLS messages
761 even if the packet is not fragmented; this may be needed with some
762 authentication servers
763 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
764 using drivers that take care of AP selection (e.g., when using
766 * fixed reprocessing of pending request after ctrl_iface requests for
767 identity/password/otp
768 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
769 EAP-PEAP and EAP-TTLS
770 * all drivers using driver_wext: set interface up and select Managed
771 mode when starting wpa_supplicant; set interface down when exiting
772 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
773 ipw2100 and ipw2200; please note that this also changed the
774 configuration variable in .config to CONFIG_DRIVER_IPW
777 * fixed a busy loop introduced in v0.3.5 for scan result processing
778 when no matching AP is found
781 * added a workaround for an interoperability issue with a Cisco AP
783 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
784 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
785 retransmission of dropped frames)
786 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
787 (e.g., segfault when processing EAPOL-Key frames)
788 * fixed EAP workaround and fast reauthentication configuration for
789 RSN pre-authentication; previously these were disabled and
790 pre-authentication would fail if the used authentication server
791 requires EAP workarounds
792 * added support for blacklisting APs that fail or timeout
793 authentication in ap_scan=1 mode so that all APs are tried in cases
794 where the ones with strongest signal level are failing authentication
795 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
796 authentication attempt
797 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
798 in the previous authentication (previously, only Phase 1 success was
802 * added preliminary support for IBSS (ad-hoc) mode configuration
803 (mode=1 in network block); this included a new key_mgmt mode
804 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
805 key management; see wpa_supplicant.conf for more details and an
806 example on how to configure this (note: this is currently implemented
807 only for driver_hostapd.c, but the changes should be trivial to add
808 in associate() handler for other drivers, too (assuming the driver
810 * added preliminary port for native Windows (i.e., no cygwin) using
814 * added optional support for GNU Readline and History Libraries for
815 wpa_cli (CONFIG_READLINE)
816 * cleaned up EAP state machine <-> method interface and number of
817 small problems with error case processing not terminating on
818 EAP-Failure but waiting for timeout
819 * added couple of workarounds for interoperability issues with a
820 Cisco AP when using WPA2
821 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
822 Note: This requires a patch for openssl to add support for TLS
823 extensions and number of workarounds for operations without
824 certificates. Proof of concept type of experimental patch is
825 included in openssl-tls-extensions.patch.
828 * fixed private key loading for cases where passphrase is not set
829 * fixed Windows/cygwin L2 packet handler freeing; previous version
830 could cause a segfault when RSN pre-authentication was completed
831 * added support for PMKSA caching with drivers that generate RSN IEs
832 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
833 but similar code can be easily added to driver_ndiswrapper.c once
834 ndiswrapper gets full support for RSN PMKSA caching
835 * improved recovery from PMKID mismatches by requesting full EAP
836 authentication in case of failed PMKSA caching attempt
837 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
838 (this requires that ndis_events is ran while wpa_supplicant is
840 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
841 * added support for driver interfaces to replace the interface name
842 based on driver/OS specific mapping, e.g., in case of driver_ndis,
843 this allows the beginning of the adapter description to be used as
845 * added support for CR+LF (Windows-style) line ends in configuration
847 * driver_ndis: enable radio before starting scanning, disable radio
849 * modified association event handler to set portEnabled = FALSE before
850 clearing port Valid in order to reset EAP state machine and avoid
851 problems with new authentication getting ignored because of state
852 machines ending up in AUTHENTICATED/SUCCESS state based on old
854 * added support for driver events to add PMKID candidates in order to
855 allow drivers to give priority to most likely roaming candidates
856 * driver_hostap: moved PrivacyInvoked configuration to associate()
857 function so that this will not be set for plaintext connections
858 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
859 interface can distinguish plaintext and IEEE 802.1X (no WPA)
861 * fixed static WEP key configuration to use broadcast/default type for
862 all keys (previously, the default TX key was configured as pairwise/
864 * driver_ndis: added legacy WPA capability detection for non-WPA2
866 * added support for setting static WEP keys for IEEE 802.1X without
867 dynamic WEP keying (eapol_flags=0)
870 * added support for reading PKCS#12 (PFX) files (as a replacement for
871 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
872 * fixed compilation with CONFIG_PCSC=y
873 * added new ap_scan mode, ap_scan=2, for drivers that take care of
874 association, but need to be configured with security policy and SSID,
875 e.g., ndiswrapper and NDIS driver; this mode should allow such
876 drivers to work with hidden SSIDs and optimized roaming; when
877 ap_scan=2 is used, only the first network block in the configuration
878 file is used and this configuration should have explicit security
879 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
880 group, proto variables
881 * added experimental port of wpa_supplicant for Windows
882 - driver_ndis.c driver interface (NDIS OIDs)
883 - currently, this requires cygwin and WinPcap
884 - small utility, win_if_list, can be used to get interface name
885 * control interface can now be removed at build time; add
886 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
887 * optional Xsupplicant interface can now be removed at build time;
888 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
889 * added auth_alg to driver interface associate() parameters to make it
890 easier for drivers to configure authentication algorithm as part of
893 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
894 * driver_broadcom: added new driver interface for Broadcom wl.o driver
895 (a generic driver for Broadcom IEEE 802.11a/g cards)
896 * wpa_cli: fixed parsing of -p <path> command line argument
897 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
898 ACK, not tunneled EAP-Success (of which only the first byte was
899 actually send due to a bug in previous code); this seems to
900 interoperate with most RADIUS servers that implements PEAPv1
901 * PEAPv1: added support for terminating PEAP authentication on tunneled
902 EAP-Success message; this can be configured by adding
903 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
904 (some RADIUS servers require this whereas others require a tunneled
906 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
907 the old label for key derivation; previously, the default was 1,
908 but it looks like most existing PEAPv1 implementations use the old
909 label which is thus more suitable default option
910 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
911 * fixed parsing of wep_tx_keyidx
912 * added support for configuring list of allowed Phase 2 EAP types
913 (for both EAP-PEAP and EAP-TTLS) instead of only one type
914 * added support for configuring IEEE 802.11 authentication algorithm
915 (auth_alg; mainly for using Shared Key authentication with static
917 * added support for EAP-AKA (with UMTS SIM)
918 * fixed couple of errors in PCSC handling that could have caused
919 random-looking errors for EAP-SIM
920 * added support for EAP-SIM pseudonyms and fast re-authentication
921 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
923 * added support for EAP-SIM with two challanges
924 (phase1="sim_min_num_chal=3" can be used to require three challenges)
925 * added support for configuring DH/DSA parameters for an ephemeral DH
926 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
927 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
928 and optional DH key exchange to achieve forward secracy with RSA keys
929 * added support for matching subject of the authentication server
930 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
931 configuration variables subject_match and subject_match2
932 * changed SSID configuration in driver_wext.c (used by many driver
933 interfaces) to use ssid_len+1 as the length for SSID since some Linux
935 * fixed couple of unaligned reads in scan result parsing to fix WPA
936 connection on some platforms (e.g., ARM)
937 * added driver interface for Intel ipw2100 driver
938 * added support for LEAP with WPA
939 * added support for larger scan results report (old limit was 4 kB of
940 data, i.e., about 35 or so APs) when using Linux wireless extensions
942 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
943 only if there is a PMKSA cache entry for the current AP
944 * fixed error handling for case where reading of scan results fails:
945 must schedule a new scan or wpa_supplicant will remain waiting
947 * changed debug output to remove shared password/key material by
948 default; all key information can be included with -K command line
949 argument to match the previous behavior
950 * added support for timestamping debug log messages (disabled by
951 default, can be enabled with -t command line argument)
952 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
953 if keys are not configured to be used; this fixes IEEE 802.1X mode
954 with drivers that use this information to configure whether Privacy
955 bit can be in Beacon frames (e.g., ndiswrapper)
956 * avoid clearing driver keys if no keys have been configured since last
957 key clear request; this seems to improve reliability of group key
958 handshake for ndiswrapper & NDIS driver which seems to be suffering
959 of some kind of timing issue when the keys are cleared again after
961 * changed driver interface API:
962 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
963 version is being used (now, this is set to 2; previously, it was
965 - pass pointer to private data structure to all calls
966 - the new API is not backwards compatible; all in-tree driver
967 interfaces has been converted to the new API
968 * added support for controlling multiple interfaces (radios) per
969 wpa_supplicant process; each interface needs to be listed on the
970 command line (-c, -i, -D arguments) with -N as a separator
971 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
972 * added a workaround for EAP servers that incorrectly use same Id for
973 sequential EAP packets
974 * changed libpcap/libdnet configuration to use .config variable,
975 CONFIG_DNET_PCAP, instead of requiring Makefile modification
976 * improved downgrade attack detection in IE verification of msg 3/4:
977 verify both WPA and RSN IEs, if present, not only the selected one;
978 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
979 Probe Response frame, and RSN is enabled in wpa_supplicant
981 * fixed WPA msg 3/4 processing to allow Key Data field contain other
982 IEs than just one WPA IE
983 * added support for FreeBSD and driver interface for the BSD net80211
984 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
985 required kernel mods have not yet been committed
986 * made EAP workarounds configurable; enabled by default, can be
987 disabled with network block option eap_workaround=0
989 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
990 * resolved couple of interoperability issues with EAP-PEAPv1 and
991 Phase 2 (inner EAP) fragment reassembly
992 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
993 AP is using non-zero key index for the unicast key and key index zero
994 for the broadcast key
995 * driver_hostap: fixed IEEE 802.1X WEP key updates and
996 re-authentication by allowing unencrypted EAPOL frames when not using
998 * added a new driver interface, 'wext', which uses only standard,
999 driver independent functionality in Linux wireless extensions;
1000 currently, this can be used only for non-WPA IEEE 802.1X mode, but
1001 eventually, this is to be extended to support full WPA/WPA2 once
1002 Linux wireless extensions get support for this
1003 * added support for mode in which the driver is responsible for AP
1004 scanning and selection; this is disabled by default and can be
1005 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
1006 this mode can be used, e.g., with generic 'wext' driver interface to
1007 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
1008 supporting wireless extensions.
1009 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
1010 operation with an AP that does not include SSID in the Beacon frames)
1011 * added support for new EAP authentication methods:
1012 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
1013 * added support for asking one-time-passwords from frontends (e.g.,
1014 wpa_cli); this 'otp' command works otherwise like 'password' command,
1015 but the password is used only once and the frontend will be asked for
1016 a new password whenever a request from authenticator requires a
1017 password; this can be used with both EAP-OTP and EAP-GTC
1018 * changed wpa_cli to automatically re-establish connection so that it
1019 does not need to be re-started when wpa_supplicant is terminated and
1021 * improved user data (identity/password/otp) requests through
1022 frontends: process pending EAPOL packets after getting new
1023 information so that full authentication does not need to be
1024 restarted; in addition, send pending requests again whenever a new
1025 frontend is attached
1026 * changed control frontends to use a new directory for socket files to
1027 make it easier for wpa_cli to automatically select between interfaces
1028 and to provide access control for the control interface;
1029 wpa_supplicant.conf: ctrl_interface is now a path
1030 (/var/run/wpa_supplicant is the recommended path) and
1031 ctrl_interface_group can be used to select which group gets access to
1032 the control interface;
1033 wpa_cli: by default, try to connect to the first interface available
1034 in /var/run/wpa_supplicant; this path can be overriden with -p option
1035 and an interface can be selected with -i option (i.e., in most common
1036 cases, wpa_cli does not need to get any arguments)
1037 * added support for LEAP
1038 * added driver interface for Linux ndiswrapper
1039 * added priority option for network blocks in the configuration file;
1040 this allows networks to be grouped based on priority (the scan
1041 results are searched for matches with network blocks in this order)
1044 * sort scan results to improve AP selection
1045 * fixed control interface socket removal for some error cases
1046 * improved scan requesting and authentication timeout
1047 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1049 * PEAP version can now be forced with phase1="peapver=<ver>"
1050 (mostly for testing; by default, the highest version supported by
1051 both the Supplicant and Authentication Server is selected
1053 * added support for madwifi driver (Atheros ar521x)
1054 * added a workaround for cases where AP sets Install Tx/Rx bit for
1055 WPA Group Key messages when pairwise keys are used (without this,
1056 the Group Key would be used for Tx and the AP would drop frames
1058 * added GSM SIM/USIM interface for GSM authentication algorithm for
1059 EAP-SIM; this requires pcsc-lite
1060 * added support for ATMEL AT76C5XXx driver
1061 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1062 does not include key data in the EAPOL-Key frame (i.e., part of
1063 EAP keying material is used as data encryption key)
1064 * added support for using plaintext and static WEP networks
1068 * added support for new EAP authentication methods:
1069 EAP-TTLS/EAP-MD5-Challenge
1071 EAP-TTLS/EAP-MSCHAPv2
1079 EAP-PEAP/MD5-Challenge
1081 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1082 * added support for anonymous identity (to be used when identity is
1083 sent in plaintext; real identity will be used within TLS protected
1084 tunnel (e.g., with EAP-TTLS)
1085 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1086 * added support for requesting identity and password information using
1087 control interface; in other words, the password for EAP-PEAP or
1088 EAP-TTLS does not need to be included in the configuration file since
1089 a frontand (e.g., wpa_cli) can ask it from the user
1090 * improved RSN pre-authentication to use a candidate list and process
1091 all candidates from each scan; not only one per scan
1092 * fixed RSN IE and WPA IE capabilities field parsing
1093 * ignore Tx bit in GTK IE when Pairwise keys are used
1094 * avoid making new scan requests during IEEE 802.1X negotiation
1095 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1096 with TLS support (this replaces the included implementation with
1097 library code to save about 8 kB since the library code is needed
1099 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1100 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1103 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1105 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1106 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1107 - EAP-MD5 (cannot be used with WPA-RADIUS)
1108 [draft-ietf-eap-rfc2284bis-09.txt]
1109 - EAP-TLS [RFC 2716]
1110 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1111 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1112 [draft-kamath-pppext-eap-mschapv2-00.txt]
1113 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1114 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1115 - new configuration file options: eap, identity, password, ca_cert,
1116 client_cert, privatekey, private_key_passwd
1117 - Xsupplicant is not required anymore, but it can be used by
1118 disabling the internal IEEE 802.1X Supplicant with -e command line
1120 - this code is not included in the default build; Makefile need to
1121 be edited for this (uncomment lines for selected functionality)
1122 - EAP-TLS and EAP-PEAP require openssl libraries
1123 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1124 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1125 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1126 EAPOL-Key frames instead of WPA key handshakes)
1127 * added support for IEEE 802.11i/RSN (WPA2)
1128 - improved PTK Key Handshake
1129 - PMKSA caching, pre-authentication
1130 * fixed wpa_supplicant to ignore possible extra data after WPA
1131 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1132 TPTK' error from message 3 of 4-Way Handshake in case the AP
1133 includes extra data after the EAPOL-Key)
1134 * added interface for external programs (frontends) to control
1136 - CLI example (wpa_cli) with interactive mode and command line
1138 - replaced SIGUSR1 status/statistics with the new control interface
1139 * made some feature compile time configurable
1140 - .config file for make
1141 - driver interfaces (hostap, hermes, ..)
1142 - EAPOL/EAP functions
1145 * Initial version of wpa_supplicant
