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,
19 * added support for SHA-256 as X.509 certificate digest when using the
20 internal X.509/TLSv1 implementation
21 * updated management frame protection to use IEEE 802.11w/D6.0
22 * added support for using SHA256-based stronger key derivation for WPA2
24 * fixed FT (IEEE 802.11r) authentication after a failed association to
26 * added support for configuring Phase 2 (inner/tunneled) authentication
27 method with wpa_gui-qt4
30 * added support for EAP Sequences in EAP-FAST Phase 2
31 * added support for using TNC with EAP-FAST
32 * added driver_ps3 for the PS3 Linux wireless driver
33 * added support for optional cryptobinding with PEAPv0
34 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
35 allow fallback to full handshake if server rejects PAC-Opaque
36 * added fragmentation support for EAP-TNC
37 * added support for parsing PKCS #8 formatted private keys into the
38 internal TLS implementation (both PKCS #1 RSA key and PKCS #8
39 encapsulated RSA key can now be used)
40 * added option of using faster, but larger, routines in the internal
41 LibTomMath (for internal TLS implementation) to speed up DH and RSA
42 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
43 * fixed race condition between disassociation event and group key
44 handshake to avoid getting stuck in incorrect state [Bug 261]
45 * fixed opportunistic key caching (proactive_key_caching)
48 * removed 'nai' and 'eappsk' network configuration variables that were
49 previously used for configuring user identity and key for EAP-PSK,
50 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
51 replacement for 'nai' (if old configuration used a separate
52 'identity' value, that would now be configured as
53 'anonymous_identity'). 'password' field is now used as the
54 replacement for 'eappsk' (it can also be set using hexstring to
55 present random binary data)
56 * removed '-w' command line parameter (wait for interface to be added,
57 if needed); cleaner way of handling this functionality is to use an
58 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
59 when an interface is added
60 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
61 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
62 indicating when new scan results become available
63 * added new ctrl_iface command, BSS, to allow scan results to be
64 fetched without hitting the message size limits (this command
65 can be used to iterate through the scan results one BSS at the time)
66 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
67 attributes in EAP-SIM Start/Response when using fast reauthentication
68 * fixed EAPOL not to end up in infinite loop when processing dynamic
69 WEP keys with IEEE 802.1X
70 * fixed problems in getting NDIS events from WMI on Windows 2000
73 * added support for Makefile builds to include debug-log-to-a-file
74 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
75 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
76 lengths properly to avoid potential crash caused by invalid messages
77 * added data structure for storing allocated buffers (struct wpabuf);
78 this does not affect wpa_supplicant usage, but many of the APIs
79 changed and various interfaces (e.g., EAP) is not compatible with old
81 * added support for protecting EAP-AKA/Identity messages with
82 AT_CHECKCODE (optional feature in RFC 4187)
83 * added support for protected result indication with AT_RESULT_IND for
84 EAP-SIM and EAP-AKA (phase1="result_ind=1")
85 * added driver_wext workaround for race condition between scanning and
86 association with drivers that take very long time to scan all
87 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
88 using a longer hardcoded timeout for the scan if the driver supports
89 notifications for scan completion (SIOCGIWSCAN event); this helps,
90 e.g., in cases where wpa_supplicant and madwifi driver ended up in
91 loop where the driver did not even try to associate
92 * stop EAPOL timer tick when no timers are in use in order to reduce
93 power consumption (no need to wake up the process once per second)
95 * added support for privilege separation (run only minimal part of
96 wpa_supplicant functionality as root and rest as unprivileged,
97 non-root process); see 'Privilege separation' in README for details;
98 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
100 * changed scan results data structure to include all information
101 elements to make it easier to support new IEs; old get_scan_result()
102 driver_ops is still supported for backwards compatibility (results
103 are converted internally to the new format), but all drivers should
104 start using the new get_scan_results2() to make them more likely to
105 work with new features
106 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
107 application, i.e., it does not require Qt3Support anymore; Windows
108 binary of wpa_gui.exe is now from this directory and only requires
109 QtCore4.dll and QtGui4.dll libraries
110 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
111 available as a separate package to make wpa_gui installation easier:
112 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
113 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
114 only shared key/password authentication is supported in this version
117 * added support for configuring password as NtPasswordHash
118 (16-byte MD4 hash of password) in hash:<32 hex digits> format
119 * added support for fallback from abbreviated TLS handshake to
120 full handshake when using EAP-FAST (e.g., due to an expired
122 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
123 draft (draft-ietf-emu-eap-gpsk-07.txt)
124 * added support for drivers that take care of RSN 4-way handshake
125 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
126 WPA_ALG_PMK in set_key)
127 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
128 .config); this version supports only ap_scan=2 mode and allow the
129 driver to take care of the 4-way handshake
130 * fixed a buffer overflow in parsing TSF from scan results when using
131 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
133 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
134 * fixed an integer overflow issue in the ASN.1 parser used by the
135 (experimental) internal TLS implementation to avoid a potential
137 * fixed a race condition with -W option (wait for a control interface
138 monitor before starting) that could have caused the first messages to
140 * added support for processing TNCC-TNCS-Messages to report
141 recommendation (allow/none/isolate) when using TNC [Bug 243]
144 * added network configuration parameter 'frequency' for setting
145 initial channel for IBSS (adhoc) networks
146 * added experimental IEEE 802.11r/D6.0 support
147 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
148 * updated EAP-PSK to use the IANA-allocated EAP type 47
149 * fixed EAP-PAX key derivation
150 * fixed EAP-PSK bit ordering of the Flags field
151 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
152 tunnelled identity request (previously, the identifier from the outer
153 method was used, not the tunnelled identifier which could be
155 * added support for fragmentation of outer TLS packets during Phase 2
156 of EAP-PEAP/TTLS/FAST
157 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
158 * added support for EAP-FAST authentication with inner methods that
159 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
160 for PAC provisioning)
161 * added support for authenticated EAP-FAST provisioning
162 * added support for configuring maximum number of EAP-FAST PACs to
163 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
164 * added support for storing EAP-FAST PACs in binary format
165 (fast_pac_format=binary in phase1 string)
166 * fixed dbus ctrl_iface to validate message interface before
167 dispatching to avoid a possible segfault [Bug 190]
168 * fixed PeerKey key derivation to use the correct PRF label
169 * updated Windows binary build to link against OpenSSL 0.9.8d and
170 added support for EAP-FAST
171 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
172 draft (draft-ietf-emu-eap-gpsk-04.txt)
173 * fixed EAP-AKA Notification processing to allow Notification to be
174 processed after AKA Challenge response has been sent
175 * updated to use IEEE 802.11w/D2.0 for management frame protection
177 * fixed EAP-TTLS implementation not to crash on use of freed memory
178 if TLS library initialization fails
179 * added support for EAP-TNC (Trusted Network Connect)
180 (this version implements the EAP-TNC method and EAP-TTLS changes
181 needed to run two methods in sequence (IF-T) and the IF-IMC and
182 IF-TNCCS interfaces from TNCC)
185 * added experimental, integrated TLSv1 client implementation with the
186 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
187 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
188 .config); this can be useful, e.g., if the target system does not
189 have a suitable TLS library and a minimal code size is required
190 (total size of this internal TLS/crypto code is bit under 50 kB on
191 x86 and the crypto code is shared by rest of the supplicant so some
192 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
193 * removed STAKey handshake since PeerKey handshake has replaced it in
194 IEEE 802.11ma and there are no known deployments of STAKey
195 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
196 draft (draft-ietf-emu-eap-gpsk-01.txt)
197 * added preliminary implementation of IEEE 802.11w/D1.0 (management
199 (Note: this requires driver support to work properly.)
200 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
201 * fixed Windows named pipes ctrl_iface to not stop listening for
202 commands if client program opens a named pipe and closes it
203 immediately without sending a command
204 * fixed USIM PIN status determination for the case that PIN is not
205 needed (this allows EAP-AKA to be used with USIM cards that do not
207 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
208 be used with cards that do not support file selection based on
210 * added support for matching the subjectAltName of the authentication
211 server certificate against multiple name components (e.g.,
212 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
213 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
214 affects IEEE 802.1X with dynamic WEP keys)
215 * changed ctrl_iface network configuration 'get' operations to not
216 return password/key material; if these fields are requested, "*"
217 will be returned if the password/key is set, but the value of the
218 parameter is not exposed
221 * added support for building Windows version with UNICODE defined
222 (wide-char functions)
223 * driver_ndis: fixed static WEP configuration to avoid race condition
224 issues with some NDIS drivers between association and setting WEP
226 * driver_ndis: added validation for IELength value in scan results to
227 avoid crashes when using buggy NDIS drivers [Bug 165]
228 * fixed Release|Win32 target in the Visual Studio project files
229 (previously, only Debug|Win32 target was set properly)
230 * changed control interface API call wpa_ctrl_pending() to allow it to
231 return -1 on error (e.g., connection lost); control interface clients
232 will need to make sure that they verify that the value is indeed >0
233 when determining whether there are pending messages
234 * added an alternative control interface backend for Windows targets:
235 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
236 control interface mechanism for Windows builds (previously, UDP to
238 * changed ctrl_interface configuration for UNIX domain sockets:
239 - deprecated ctrl_interface_group variable (it may be removed in
241 - allow both directory and group be configured with ctrl_interface
242 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
243 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
244 case when group is not changed
245 * added support for controlling more than one interface per process in
247 * added a workaround for a case where the AP is using unknown address
248 (e.g., MAC address of the wired interface) as the source address for
249 EAPOL-Key frames; previously, that source address was used as the
250 destination for EAPOL-Key frames and in key derivation; now, BSSID is
251 used even if the source address does not match with it
252 (this resolves an interoperability issue with Thomson SpeedTouch 580)
253 * added a workaround for UDP-based control interface (which was used in
254 Windows builds before this release) to prevent packets with forged
255 addresses from being accepted as local control requests
256 * removed ndis_events.cpp and possibility of using external
257 ndis_events.exe; C version (ndis_events.c) is fully functional and
258 there is no desire to maintain two separate versions of this
260 * ndis_events: Changed NDIS event notification design to use WMI to
261 learn the adapter description through Win32_PnPEntity class; this
262 should fix some cases where the adapter name was not recognized
263 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
265 * fixed selection of the first network in ap_scan=2 mode; previously,
266 wpa_supplicant could get stuck in SCANNING state when only the first
267 network for enabled (e.g., after 'wpa_cli select_network 0')
268 * winsvc: added support for configuring ctrl_interface parameters in
269 registry (ctrl_interface string value in
270 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
271 required to enable control interface (previously, this was hardcoded
273 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
274 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
277 * fixed build with CONFIG_STAKEY=y [Bug 143]
278 * added support for doing MLME (IEEE 802.11 management frame
279 processing) in wpa_supplicant when using Devicescape IEEE 802.11
280 stack (wireless-dev.git tree)
281 * added a new network block configuration option, fragment_size, to
282 configure the maximum EAP fragment size
283 * driver_ndis: Disable WZC automatically for the selected interface to
284 avoid conflicts with two programs trying to control the radio; WZC
285 will be re-enabled (if it was enabled originally) when wpa_supplicant
287 * added an experimental TLSv1 client implementation
288 (CONFIG_TLS=internal) that can be used instead of an external TLS
289 library, e.g., to reduce total size requirement on systems that do
290 not include any TLS library by default (this is not yet complete;
291 basic functionality is there, but certificate validation is not yet
293 * added PeerKey handshake implementation for IEEE 802.11e
294 direct link setup (DLS) to replace STAKey handshake
295 * fixed WPA PSK update through ctrl_iface for the case where the old
296 PSK was derived from an ASCII passphrase and the new PSK is set as
297 a raw PSK (hex string)
298 * added new configuration option for identifying which network block
299 was used (id_str in wpa_supplicant.conf; included on
300 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
301 variable in wpa_cli action scripts; in addition WPA_ID variable is
302 set to the current unique identifier that wpa_supplicant assigned
303 automatically for the network and that can be used with
304 GET_NETWORK/SET_NETWORK ctrl_iface commands)
305 * wpa_cli action script is now called only when the connect/disconnect
306 status changes or when associating with a different network
307 * fixed configuration parser not to remove CCMP from group cipher list
308 if WPA-None (adhoc) is used (pairwise=NONE in that case)
309 * fixed integrated NDIS events processing not to hang the process due
310 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
311 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
312 draft-clancy-emu-eap-shared-secret-00.txt)
313 * added Microsoft Visual Studio 2005 solution and project files for
314 build wpa_supplicant for Windows (see vs2005 subdirectory)
315 * eloop_win: fixed unregistration of Windows events
316 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
317 at the end of RSN pre-authentication and added unregistration of
318 a Windows event to avoid getting eloop_win stuck with an invalid
320 * driver_ndis: added support for selecting AP based on BSSID
321 * added new environmental variable for wpa_cli action scripts:
322 WPA_CTRL_DIR is the current control interface directory
323 * driver_ndis: added support for using NDISUIO instead of WinPcap for
324 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
325 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
326 wpa_supplicant without requiring WinPcap; note that using NDISUIO
327 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
328 only one application to open the device
329 * changed NDIS driver naming to only include device GUID, e.g.,
330 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
331 specific \Device\NPF_ prefix before the GUID; the prefix is still
332 allowed for backwards compatibility, but it is not required anymore
333 when specifying the interface
334 * driver_ndis: re-initialize driver interface is the adapter is removed
335 and re-inserted [Bug 159]
336 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
337 big endian hosts [Bug 146]
340 * fixed EAP-GTC response to include correct user identity when run as
341 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
342 * driver_ndis: Fixed encryption mode configuration for unencrypted
343 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
344 refused to associate with open networks) [Bug 106]
345 * driver_ndis: use BSSID OID polling to detect when IBSS network is
346 formed even when ndis_events code is included since some NDIS drivers
347 do not generate media connect events in IBSS mode
348 * config_winreg: allow global ctrl_interface parameter to be configured
350 * config_winreg: added support for saving configuration data into
352 * added support for controlling network device operational state
353 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
354 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
355 that can use this information)
356 * driver_wext: added support for WE-21 change to SSID configuration
357 * driver_wext: fixed privacy configuration for static WEP keys mode
359 * added an optional driver_ops callback for MLME-SETPROTECTION.request
361 * added support for EAP-SAKE (no EAP method number allocated yet, so
362 this is using the same experimental type 255 as EAP-PSK)
363 * added support for dynamically loading EAP methods (.so files) instead
364 of requiring them to be statically linked in; this is disabled by
365 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
369 * do not try to use USIM APDUs when initializing PC/SC for SIM card
370 access for a network that has not enabled EAP-AKA
371 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
372 v0.5.1 due to the new support for expanded EAP types)
373 * added support for generating EAP Expanded Nak
374 * try to fetch scan results once before requesting new scan when
375 starting up in ap_scan=1 mode (this can speed up initial association
376 a lot with, e.g., madwifi-ng driver)
377 * added support for receiving EAPOL frames from a Linux bridge
378 interface (-bbr0 on command line)
379 * fixed EAPOL re-authentication for sessions that used PMKSA caching
380 * changed EAP method registration to use a dynamic list of methods
381 instead of a static list generated at build time
382 * fixed PMKSA cache deinitialization not to use freed memory when
383 removing PMKSA entries
384 * fixed a memory leak in EAP-TTLS re-authentication
385 * reject WPA/WPA2 message 3/4 if it does not include any valid
387 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
388 if the driver does not support SIOCSIWAUTH
391 * driver_test: added better support for multiple APs and STAs by using
392 a directory with sockets that include MAC address for each device in
393 the name (driver_param=test_dir=/tmp/test)
394 * added support for EAP expanded type (vendor specific EAP methods)
395 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
396 option can be changed if needed
397 * wpa_cli/wpa_gui: skip non-socket files in control directory when
398 using UNIX domain sockets; this avoids selecting an incorrect
399 interface (e.g., a PID file could be in this directory, even though
400 use of this directory for something else than socket files is not
402 * fixed TLS library deinitialization after RSN pre-authentication not
403 to disable TLS library for normal authentication
404 * driver_wext: Remove null-termination from SSID length if the driver
405 used it; some Linux drivers do this and they were causing problems in
406 wpa_supplicant not finding matching configuration block. This change
407 would break a case where the SSID actually ends in '\0', but that is
408 not likely to happen in real use.
409 * fixed PMKSA cache processing not to trigger deauthentication if the
410 current PMKSA cache entry is replaced with a valid new entry
411 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
412 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
415 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
416 * added experimental STAKey handshake implementation for IEEE 802.11e
417 direct link setup (DLS); note: this is disabled by default in both
418 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
420 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
421 decrypt AT_ENCR_DATA attributes correctly
422 * fixed EAP-AKA to allow resynchronization within the same session
423 * made code closer to ANSI C89 standard to make it easier to port to
424 other C libraries and compilers
425 * started moving operating system or C library specific functions into
426 wrapper functions defined in os.h and implemented in os_*.c to make
428 * wpa_supplicant can now be built with Microsoft Visual C++
429 (e.g., with the freely available Toolkit 2003 version or Visual
430 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
431 example makefile for nmake
432 * added support for using Windows registry for command line parameters
433 (CONFIG_MAIN=main_winsvc) and configuration data
434 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
435 contents; this version can be run both as a Windows service and as a
436 normal application; 'wpasvc.exe app' to start as applicant,
437 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
438 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
440 * made it possible to link ndis_events.exe functionality into
441 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
442 * added better support for multiple control interface backends
443 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
444 * fixed PC/SC code to use correct length for GSM AUTH command buffer
445 and to not use pioRecvPci with SCardTransmit() calls; these were not
446 causing visible problems with pcsc-lite, but Windows Winscard.dll
447 refused the previously used parameters; this fixes EAP-SIM and
448 EAP-AKA authentication using SIM/USIM card under Windows
449 * added new event loop implementation for Windows using
450 WaitForMultipleObject() instead of select() in order to allow waiting
451 for non-socket objects; this can be selected with
452 CONFIG_ELOOP=eloop_win in .config
453 * added support for selecting l2_packet implementation in .config
454 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
455 winpcap, freebsd, none)
456 * added new l2_packet implementation for WinPcap
457 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
458 reduce latency in EAPOL receive processing from about 100 ms to about
460 * added support for EAP-FAST key derivation using other ciphers than
461 RC4-128-SHA for authentication and AES128-SHA for provisioning
462 * added support for configuring CA certificate as DER file and as a
464 * fixed private key configuration as configuration blob and added
465 support for using PKCS#12 as a blob
466 * tls_gnutls: added support for using PKCS#12 files; added support for
468 * added support for loading trusted CA certificates from Windows
469 certificate store: ca_cert="cert_store://<name>", where <name> is
470 likely CA (Intermediate CA certificates) or ROOT (root certificates)
471 * added C version of ndis_events.cpp and made it possible to build this
472 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
473 easily on cross-compilation builds
474 * added wpasvc.exe into Windows binary release; this is an alternative
475 version of wpa_supplicant.exe with configuration backend using
476 Windows registry and with the entry point designed to run as a
478 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
479 wpasvc.exe and removed this additional tool from the Windows binary
480 release since it is not needed anymore
481 * load winscard.dll functions dynamically when building with MinGW
482 since MinGW does not yet include winscard library
484 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
485 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
486 and WinPcap to receive frames sent to PAE group address
487 * disable EAP state machine when IEEE 802.1X authentication is not used
488 in order to get rid of bogus "EAP failed" messages
489 * fixed OpenSSL error reporting to go through all pending errors to
490 avoid confusing reports of old errors being reported at later point
492 * fixed configuration file updating to not write empty variables
493 (e.g., proto or key_mgmt) that the file parser would not accept
494 * fixed ADD_NETWORK ctrl_iface command to use the same default values
495 for variables as empty network definitions read from config file
497 * fixed EAP state machine to not discard EAP-Failure messages in many
498 cases (e.g., during TLS handshake)
499 * fixed a infinite loop in private key reading if the configured file
500 cannot be parsed successfully
501 * driver_madwifi: added support for madwifi-ng
502 * wpa_gui: do not display password/PSK field contents
503 * wpa_gui: added CA certificate configuration
504 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
505 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
506 the new AP is using different WPA/RSN IE
507 * use longer timeout for IEEE 802.11 association to avoid problems with
508 drivers that may take more than five second to associate
511 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
512 RSN IE, but WPA IE would match with wpa_supplicant configuration
513 * added support for named configuration blobs in order to avoid having
514 to use file system for external files (e.g., certificates);
515 variables can be set to "blob://<blob name>" instead of file path to
516 use a named blob; supported fields: pac_file, client_cert,
518 * fixed RSN pre-authentication (it was broken in the clean up of WPA
519 state machine interface in v0.4.5)
520 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
521 sure the driver configures broadcast decryption correctly
522 * added ca_path (and ca_path2) configuration variables that can be used
523 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
524 system-wide trusted CA list
525 * added support for starting wpa_supplicant without a configuration
526 file (-C argument must be used to set ctrl_interface parameter for
527 this case; in addition, -p argument can be used to provide
528 driver_param; these new arguments can also be used with a
529 configuration to override the values from the configuration)
530 * added global control interface that can be optionally used for adding
531 and removing network interfaces dynamically (-g command line argument
532 for both wpa_supplicant and wpa_cli) without having to restart
533 wpa_supplicant process
535 - try to save configuration whenever something is modified
536 - added WEP key configuration
537 - added possibility to edit the current network configuration
538 * driver_ndis: fixed driver polling not to increase frequency on each
539 received EAPOL frame due to incorrectly cancelled timeout
540 * added simple configuration file examples (in examples subdirectory)
541 * fixed driver_wext.c to filter wireless events based on ifindex to
542 avoid interfaces receiving events from other interfaces
543 * delay sending initial EAPOL-Start couple of seconds to speed up
544 authentication for the most common case of Authenticator starting
545 EAP authentication immediately after association
548 * added a workaround for clearing keys with ndiswrapper to allow
549 roaming from WPA enabled AP to plaintext one
550 * added docbook documentation (doc/docbook) that can be used to
551 generate, e.g., man pages
552 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
553 PF_PACKET in order to prepare for network devices that do not use
554 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
555 * use receipt of EAPOL-Key frame as a lower layer success indication
556 for EAP state machine to allow recovery from dropped EAP-Success
558 * cleaned up internal EAPOL frame processing by not including link
559 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
560 header is added only when transmitted the frame; this makes it easier
561 to use wpa_supplicant on link layers that use different header than
563 * updated EAP-PSK to use draft 9 by default since this can now be
564 tested with hostapd; removed support for draft 3, including
565 server_nai configuration option from network blocks
566 * driver_wired: add PAE address to the multicast address list in order
567 to be able to receive EAPOL frames with drivers that do not include
568 these multicast addresses by default
569 * driver_wext: add support for WE-19
570 * added support for multiple configuration backends (CONFIG_BACKEND
571 option); currently, only 'file' is supported (i.e., the format used
572 in wpa_supplicant.conf)
573 * added support for updating configuration ('wpa_cli save_config');
574 this is disabled by default and can be enabled with global
575 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
576 and wpa_gui to store the configuration changes in a permanent store
577 * added GET_NETWORK ctrl_iface command
578 (e.g., 'wpa_cli get_network 0 ssid')
581 * replaced OpenSSL patch for EAP-FAST support
582 (openssl-tls-extensions.patch) with a more generic and correct
583 patch (the new patch is not compatible with the previous one, so the
584 OpenSSL library will need to be patched with the new patch in order
585 to be able to build wpa_supplicant with EAP-FAST support)
586 * added support for using Windows certificate store (through CryptoAPI)
587 for client certificate and private key operations (EAP-TLS)
588 (see wpa_supplicant.conf for more information on how to configure
589 this with private_key)
590 * ported wpa_gui to Windows
591 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
592 built with the open source version of the Qt4 for Windows
593 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
594 with drivers that do not support WPA
595 * ndis_events: fixed Windows 2000 support
596 * added support for enabling/disabling networks from the list of all
597 configured networks ('wpa_cli enable_network <network id>' and
598 'wpa_cli disable_network <network id>')
599 * added support for adding and removing network from the current
600 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
601 <network id>'); added networks are disabled by default and they can
602 be enabled with enable_network command once the configuration is done
603 for the new network; note: configuration file is not yet updated, so
604 these new networks are lost when wpa_supplicant is restarted
605 * added support for setting network configuration parameters through
606 the control interface, for example:
607 wpa_cli set_network 0 ssid "\"my network\""
608 * fixed parsing of strings that include both " and # within double
609 quoted area (e.g., "start"#end")
610 * added EAP workaround for PEAP session resumption: allow outer,
611 i.e., not tunneled, EAP-Success to terminate session since; this can
612 be disabled with eap_workaround=0
613 (this was allowed for PEAPv1 before, but now it is also allowed for
614 PEAPv0 since at least one RADIUS authentication server seems to be
615 doing this for PEAPv0, too)
616 * wpa_gui: added preliminary support for adding new networks to the
617 wpa_supplicant configuration (double click on the scan results to
618 open network configuration)
621 * removed interface for external EAPOL/EAP supplicant (e.g.,
622 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
623 anymore and is unlikely to be used by anyone
624 * driver_ndis: fixed WinPcap 3.0 support
625 * fixed build with CONFIG_DNET_PCAP=y on Linux
626 * l2_packet: moved different implementations into separate files
630 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
631 (note: ipw2100-1.1.0 is likely to require an update to work with
633 * added support for using ap_scan=2 mode with multiple network blocks;
634 wpa_supplicant will go through the networks one by one until the
635 driver reports a successful association; this uses the same order for
636 networks as scan_ssid=1 scans, i.e., the priority field is ignored
637 and the network block order in the file is used instead
638 * fixed a potential issue in RSN pre-authentication ending up using
639 freed memory if pre-authentication times out
640 * added support for matching alternative subject name extensions of the
641 authentication server certificate; new configuration variables
642 altsubject_match and altsubject_match2
643 * driver_ndis: added support for IEEE 802.1X authentication with wired
645 * added support for querying private key password (EAP-TLS) through the
646 control interface (wpa_cli/wpa_gui) if one is not included in the
648 * driver_broadcom: fixed couple of memory leaks in scan result
650 * EAP-PAX is now registered as EAP type 46
651 * fixed EAP-PAX MAC calculation
652 * fixed EAP-PAX CK and ICK key derivation
653 * added support for using password with EAP-PAX (as an alternative to
654 entering key with eappsk); SHA-1 hash of the password will be used as
656 * added support for arbitrary driver interface parameters through the
657 configuration file with a new driver_param field; this adds a new
658 driver_ops function set_param()
659 * added possibility to override l2_packet module with driver interface
660 API (new send_eapol handler); this can be used to implement driver
661 specific TX/RX functions for EAPOL frames
662 * fixed ctrl_interface_group processing for the case where gid is
663 entered as a number, not group name
664 * driver_test: added support for testing hostapd with wpa_supplicant
665 by using test driver interface without any kernel drivers or network
669 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
670 packets to be encrypted; this was apparently broken by the changed
671 ioctl order in v0.4.0
672 * driver_madwifi: added preliminary support for compiling against 'BSD'
673 branch of madwifi CVS tree
674 * added support for EAP-MSCHAPv2 password retries within the same EAP
675 authentication session
676 * added support for password changes with EAP-MSCHAPv2 (used when the
677 password has expired)
678 * added support for reading additional certificates from PKCS#12 files
679 and adding them to the certificate chain
680 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
682 * fixed a possible double free in EAP-TTLS fast-reauthentication when
683 identity or password is entered through control interface
684 * display EAP Notification messages to user through control interface
685 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
686 * added GUI version of wpa_cli, wpa_gui; this is not build
687 automatically with 'make'; use 'make wpa_gui' to build (this requires
688 Qt development tools)
689 * added 'disconnect' command to control interface for setting
690 wpa_supplicant in state where it will not associate before
691 'reassociate' command has been used
692 * added support for selecting a network from the list of all configured
693 networks ('wpa_cli select_network <network id>'; this disabled all
694 other networks; to re-enable, 'wpa_cli select_network any')
695 * added support for getting scan results through control interface
696 * added EAP workaround for PEAPv1 session resumption: allow outer,
697 i.e., not tunneled, EAP-Success to terminate session since; this can
698 be disabled with eap_workaround=0
700 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
701 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
702 used to reduce the size of the wpa_supplicant considerably if
703 debugging code is not needed
704 * fixed EAPOL-Key validation to drop packets with invalid Key Data
705 Length; such frames could have crashed wpa_supplicant due to buffer
707 * added support for wired authentication (IEEE 802.1X on wired
708 Ethernet); driver interface 'wired'
709 * obsoleted set_wpa() handler in the driver interface API (it can be
710 replaced by moving enable/disable functionality into init()/deinit())
711 (calls to set_wpa() are still present for backwards compatibility,
712 but they may be removed in the future)
713 * driver_madwifi: fixed association in plaintext mode
714 * modified the EAP workaround that accepts EAP-Success with incorrect
715 Identifier to be even less strict about verification in order to
716 interoperate with some authentication servers
717 * added support for sending TLS alerts
718 * added support for 'any' SSID wildcard; if ssid is not configured or
719 is set to an empty string, any SSID will be accepted for non-WPA AP
720 * added support for asking PIN (for SIM) from frontends (e.g.,
721 wpa_cli); if a PIN is needed, but not included in the configuration
722 file, a control interface request is sent and EAP processing is
723 delayed until the PIN is available
724 * added support for using external devices (e.g., a smartcard) for
725 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
726 new wpa_supplicant.conf variables:
727 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
728 - network: engine, engine_id, key_id
729 * added experimental support for EAP-PAX
730 * added monitor mode for wpa_cli (-a<path to a program to run>) that
731 allows external commands (e.g., shell scripts) to be run based on
732 wpa_supplicant events, e.g., when authentication has been completed
733 and data connection is ready; other related wpa_cli arguments:
734 -B (run in background), -P (write PID file); wpa_supplicant has a new
735 command line argument (-W) that can be used to make it wait until a
736 control interface command is received in order to avoid missing
738 * added support for opportunistic WPA2 PMKSA key caching (disabled by
739 default, can be enabled with proactive_key_caching=1)
740 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
741 Authenticator rejects PMKSA caching attempt and the driver is not
742 using assoc_info events
743 * added -P<pid file> argument for wpa_supplicant to write the current
744 process id into a file
746 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
747 * added new phase1 option parameter, include_tls_length=1, to force
748 wpa_supplicant to add TLS Message Length field to all TLS messages
749 even if the packet is not fragmented; this may be needed with some
750 authentication servers
751 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
752 using drivers that take care of AP selection (e.g., when using
754 * fixed reprocessing of pending request after ctrl_iface requests for
755 identity/password/otp
756 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
757 EAP-PEAP and EAP-TTLS
758 * all drivers using driver_wext: set interface up and select Managed
759 mode when starting wpa_supplicant; set interface down when exiting
760 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
761 ipw2100 and ipw2200; please note that this also changed the
762 configuration variable in .config to CONFIG_DRIVER_IPW
765 * fixed a busy loop introduced in v0.3.5 for scan result processing
766 when no matching AP is found
769 * added a workaround for an interoperability issue with a Cisco AP
771 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
772 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
773 retransmission of dropped frames)
774 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
775 (e.g., segfault when processing EAPOL-Key frames)
776 * fixed EAP workaround and fast reauthentication configuration for
777 RSN pre-authentication; previously these were disabled and
778 pre-authentication would fail if the used authentication server
779 requires EAP workarounds
780 * added support for blacklisting APs that fail or timeout
781 authentication in ap_scan=1 mode so that all APs are tried in cases
782 where the ones with strongest signal level are failing authentication
783 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
784 authentication attempt
785 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
786 in the previous authentication (previously, only Phase 1 success was
790 * added preliminary support for IBSS (ad-hoc) mode configuration
791 (mode=1 in network block); this included a new key_mgmt mode
792 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
793 key management; see wpa_supplicant.conf for more details and an
794 example on how to configure this (note: this is currently implemented
795 only for driver_hostapd.c, but the changes should be trivial to add
796 in associate() handler for other drivers, too (assuming the driver
798 * added preliminary port for native Windows (i.e., no cygwin) using
802 * added optional support for GNU Readline and History Libraries for
803 wpa_cli (CONFIG_READLINE)
804 * cleaned up EAP state machine <-> method interface and number of
805 small problems with error case processing not terminating on
806 EAP-Failure but waiting for timeout
807 * added couple of workarounds for interoperability issues with a
808 Cisco AP when using WPA2
809 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
810 Note: This requires a patch for openssl to add support for TLS
811 extensions and number of workarounds for operations without
812 certificates. Proof of concept type of experimental patch is
813 included in openssl-tls-extensions.patch.
816 * fixed private key loading for cases where passphrase is not set
817 * fixed Windows/cygwin L2 packet handler freeing; previous version
818 could cause a segfault when RSN pre-authentication was completed
819 * added support for PMKSA caching with drivers that generate RSN IEs
820 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
821 but similar code can be easily added to driver_ndiswrapper.c once
822 ndiswrapper gets full support for RSN PMKSA caching
823 * improved recovery from PMKID mismatches by requesting full EAP
824 authentication in case of failed PMKSA caching attempt
825 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
826 (this requires that ndis_events is ran while wpa_supplicant is
828 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
829 * added support for driver interfaces to replace the interface name
830 based on driver/OS specific mapping, e.g., in case of driver_ndis,
831 this allows the beginning of the adapter description to be used as
833 * added support for CR+LF (Windows-style) line ends in configuration
835 * driver_ndis: enable radio before starting scanning, disable radio
837 * modified association event handler to set portEnabled = FALSE before
838 clearing port Valid in order to reset EAP state machine and avoid
839 problems with new authentication getting ignored because of state
840 machines ending up in AUTHENTICATED/SUCCESS state based on old
842 * added support for driver events to add PMKID candidates in order to
843 allow drivers to give priority to most likely roaming candidates
844 * driver_hostap: moved PrivacyInvoked configuration to associate()
845 function so that this will not be set for plaintext connections
846 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
847 interface can distinguish plaintext and IEEE 802.1X (no WPA)
849 * fixed static WEP key configuration to use broadcast/default type for
850 all keys (previously, the default TX key was configured as pairwise/
852 * driver_ndis: added legacy WPA capability detection for non-WPA2
854 * added support for setting static WEP keys for IEEE 802.1X without
855 dynamic WEP keying (eapol_flags=0)
858 * added support for reading PKCS#12 (PFX) files (as a replacement for
859 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
860 * fixed compilation with CONFIG_PCSC=y
861 * added new ap_scan mode, ap_scan=2, for drivers that take care of
862 association, but need to be configured with security policy and SSID,
863 e.g., ndiswrapper and NDIS driver; this mode should allow such
864 drivers to work with hidden SSIDs and optimized roaming; when
865 ap_scan=2 is used, only the first network block in the configuration
866 file is used and this configuration should have explicit security
867 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
868 group, proto variables
869 * added experimental port of wpa_supplicant for Windows
870 - driver_ndis.c driver interface (NDIS OIDs)
871 - currently, this requires cygwin and WinPcap
872 - small utility, win_if_list, can be used to get interface name
873 * control interface can now be removed at build time; add
874 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
875 * optional Xsupplicant interface can now be removed at build time;
876 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
877 * added auth_alg to driver interface associate() parameters to make it
878 easier for drivers to configure authentication algorithm as part of
881 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
882 * driver_broadcom: added new driver interface for Broadcom wl.o driver
883 (a generic driver for Broadcom IEEE 802.11a/g cards)
884 * wpa_cli: fixed parsing of -p <path> command line argument
885 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
886 ACK, not tunneled EAP-Success (of which only the first byte was
887 actually send due to a bug in previous code); this seems to
888 interoperate with most RADIUS servers that implements PEAPv1
889 * PEAPv1: added support for terminating PEAP authentication on tunneled
890 EAP-Success message; this can be configured by adding
891 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
892 (some RADIUS servers require this whereas others require a tunneled
894 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
895 the old label for key derivation; previously, the default was 1,
896 but it looks like most existing PEAPv1 implementations use the old
897 label which is thus more suitable default option
898 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
899 * fixed parsing of wep_tx_keyidx
900 * added support for configuring list of allowed Phase 2 EAP types
901 (for both EAP-PEAP and EAP-TTLS) instead of only one type
902 * added support for configuring IEEE 802.11 authentication algorithm
903 (auth_alg; mainly for using Shared Key authentication with static
905 * added support for EAP-AKA (with UMTS SIM)
906 * fixed couple of errors in PCSC handling that could have caused
907 random-looking errors for EAP-SIM
908 * added support for EAP-SIM pseudonyms and fast re-authentication
909 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
911 * added support for EAP-SIM with two challanges
912 (phase1="sim_min_num_chal=3" can be used to require three challenges)
913 * added support for configuring DH/DSA parameters for an ephemeral DH
914 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
915 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
916 and optional DH key exchange to achieve forward secracy with RSA keys
917 * added support for matching subject of the authentication server
918 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
919 configuration variables subject_match and subject_match2
920 * changed SSID configuration in driver_wext.c (used by many driver
921 interfaces) to use ssid_len+1 as the length for SSID since some Linux
923 * fixed couple of unaligned reads in scan result parsing to fix WPA
924 connection on some platforms (e.g., ARM)
925 * added driver interface for Intel ipw2100 driver
926 * added support for LEAP with WPA
927 * added support for larger scan results report (old limit was 4 kB of
928 data, i.e., about 35 or so APs) when using Linux wireless extensions
930 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
931 only if there is a PMKSA cache entry for the current AP
932 * fixed error handling for case where reading of scan results fails:
933 must schedule a new scan or wpa_supplicant will remain waiting
935 * changed debug output to remove shared password/key material by
936 default; all key information can be included with -K command line
937 argument to match the previous behavior
938 * added support for timestamping debug log messages (disabled by
939 default, can be enabled with -t command line argument)
940 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
941 if keys are not configured to be used; this fixes IEEE 802.1X mode
942 with drivers that use this information to configure whether Privacy
943 bit can be in Beacon frames (e.g., ndiswrapper)
944 * avoid clearing driver keys if no keys have been configured since last
945 key clear request; this seems to improve reliability of group key
946 handshake for ndiswrapper & NDIS driver which seems to be suffering
947 of some kind of timing issue when the keys are cleared again after
949 * changed driver interface API:
950 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
951 version is being used (now, this is set to 2; previously, it was
953 - pass pointer to private data structure to all calls
954 - the new API is not backwards compatible; all in-tree driver
955 interfaces has been converted to the new API
956 * added support for controlling multiple interfaces (radios) per
957 wpa_supplicant process; each interface needs to be listed on the
958 command line (-c, -i, -D arguments) with -N as a separator
959 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
960 * added a workaround for EAP servers that incorrectly use same Id for
961 sequential EAP packets
962 * changed libpcap/libdnet configuration to use .config variable,
963 CONFIG_DNET_PCAP, instead of requiring Makefile modification
964 * improved downgrade attack detection in IE verification of msg 3/4:
965 verify both WPA and RSN IEs, if present, not only the selected one;
966 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
967 Probe Response frame, and RSN is enabled in wpa_supplicant
969 * fixed WPA msg 3/4 processing to allow Key Data field contain other
970 IEs than just one WPA IE
971 * added support for FreeBSD and driver interface for the BSD net80211
972 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
973 required kernel mods have not yet been committed
974 * made EAP workarounds configurable; enabled by default, can be
975 disabled with network block option eap_workaround=0
977 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
978 * resolved couple of interoperability issues with EAP-PEAPv1 and
979 Phase 2 (inner EAP) fragment reassembly
980 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
981 AP is using non-zero key index for the unicast key and key index zero
982 for the broadcast key
983 * driver_hostap: fixed IEEE 802.1X WEP key updates and
984 re-authentication by allowing unencrypted EAPOL frames when not using
986 * added a new driver interface, 'wext', which uses only standard,
987 driver independent functionality in Linux wireless extensions;
988 currently, this can be used only for non-WPA IEEE 802.1X mode, but
989 eventually, this is to be extended to support full WPA/WPA2 once
990 Linux wireless extensions get support for this
991 * added support for mode in which the driver is responsible for AP
992 scanning and selection; this is disabled by default and can be
993 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
994 this mode can be used, e.g., with generic 'wext' driver interface to
995 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
996 supporting wireless extensions.
997 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
998 operation with an AP that does not include SSID in the Beacon frames)
999 * added support for new EAP authentication methods:
1000 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
1001 * added support for asking one-time-passwords from frontends (e.g.,
1002 wpa_cli); this 'otp' command works otherwise like 'password' command,
1003 but the password is used only once and the frontend will be asked for
1004 a new password whenever a request from authenticator requires a
1005 password; this can be used with both EAP-OTP and EAP-GTC
1006 * changed wpa_cli to automatically re-establish connection so that it
1007 does not need to be re-started when wpa_supplicant is terminated and
1009 * improved user data (identity/password/otp) requests through
1010 frontends: process pending EAPOL packets after getting new
1011 information so that full authentication does not need to be
1012 restarted; in addition, send pending requests again whenever a new
1013 frontend is attached
1014 * changed control frontends to use a new directory for socket files to
1015 make it easier for wpa_cli to automatically select between interfaces
1016 and to provide access control for the control interface;
1017 wpa_supplicant.conf: ctrl_interface is now a path
1018 (/var/run/wpa_supplicant is the recommended path) and
1019 ctrl_interface_group can be used to select which group gets access to
1020 the control interface;
1021 wpa_cli: by default, try to connect to the first interface available
1022 in /var/run/wpa_supplicant; this path can be overriden with -p option
1023 and an interface can be selected with -i option (i.e., in most common
1024 cases, wpa_cli does not need to get any arguments)
1025 * added support for LEAP
1026 * added driver interface for Linux ndiswrapper
1027 * added priority option for network blocks in the configuration file;
1028 this allows networks to be grouped based on priority (the scan
1029 results are searched for matches with network blocks in this order)
1032 * sort scan results to improve AP selection
1033 * fixed control interface socket removal for some error cases
1034 * improved scan requesting and authentication timeout
1035 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1037 * PEAP version can now be forced with phase1="peapver=<ver>"
1038 (mostly for testing; by default, the highest version supported by
1039 both the Supplicant and Authentication Server is selected
1041 * added support for madwifi driver (Atheros ar521x)
1042 * added a workaround for cases where AP sets Install Tx/Rx bit for
1043 WPA Group Key messages when pairwise keys are used (without this,
1044 the Group Key would be used for Tx and the AP would drop frames
1046 * added GSM SIM/USIM interface for GSM authentication algorithm for
1047 EAP-SIM; this requires pcsc-lite
1048 * added support for ATMEL AT76C5XXx driver
1049 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1050 does not include key data in the EAPOL-Key frame (i.e., part of
1051 EAP keying material is used as data encryption key)
1052 * added support for using plaintext and static WEP networks
1056 * added support for new EAP authentication methods:
1057 EAP-TTLS/EAP-MD5-Challenge
1059 EAP-TTLS/EAP-MSCHAPv2
1067 EAP-PEAP/MD5-Challenge
1069 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1070 * added support for anonymous identity (to be used when identity is
1071 sent in plaintext; real identity will be used within TLS protected
1072 tunnel (e.g., with EAP-TTLS)
1073 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1074 * added support for requesting identity and password information using
1075 control interface; in other words, the password for EAP-PEAP or
1076 EAP-TTLS does not need to be included in the configuration file since
1077 a frontand (e.g., wpa_cli) can ask it from the user
1078 * improved RSN pre-authentication to use a candidate list and process
1079 all candidates from each scan; not only one per scan
1080 * fixed RSN IE and WPA IE capabilities field parsing
1081 * ignore Tx bit in GTK IE when Pairwise keys are used
1082 * avoid making new scan requests during IEEE 802.1X negotiation
1083 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1084 with TLS support (this replaces the included implementation with
1085 library code to save about 8 kB since the library code is needed
1087 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1088 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1091 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1093 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1094 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1095 - EAP-MD5 (cannot be used with WPA-RADIUS)
1096 [draft-ietf-eap-rfc2284bis-09.txt]
1097 - EAP-TLS [RFC 2716]
1098 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1099 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1100 [draft-kamath-pppext-eap-mschapv2-00.txt]
1101 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1102 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1103 - new configuration file options: eap, identity, password, ca_cert,
1104 client_cert, privatekey, private_key_passwd
1105 - Xsupplicant is not required anymore, but it can be used by
1106 disabling the internal IEEE 802.1X Supplicant with -e command line
1108 - this code is not included in the default build; Makefile need to
1109 be edited for this (uncomment lines for selected functionality)
1110 - EAP-TLS and EAP-PEAP require openssl libraries
1111 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1112 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1113 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1114 EAPOL-Key frames instead of WPA key handshakes)
1115 * added support for IEEE 802.11i/RSN (WPA2)
1116 - improved PTK Key Handshake
1117 - PMKSA caching, pre-authentication
1118 * fixed wpa_supplicant to ignore possible extra data after WPA
1119 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1120 TPTK' error from message 3 of 4-Way Handshake in case the AP
1121 includes extra data after the EAPOL-Key)
1122 * added interface for external programs (frontends) to control
1124 - CLI example (wpa_cli) with interactive mode and command line
1126 - replaced SIGUSR1 status/statistics with the new control interface
1127 * made some feature compile time configurable
1128 - .config file for make
1129 - driver interfaces (hostap, hermes, ..)
1130 - EAPOL/EAP functions
1133 * Initial version of wpa_supplicant
