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)
26 * added support for SHA-256 as X.509 certificate digest when using the
27 internal X.509/TLSv1 implementation
28 * updated management frame protection to use IEEE 802.11w/D6.0
29 * added support for using SHA256-based stronger key derivation for WPA2
31 * fixed FT (IEEE 802.11r) authentication after a failed association to
33 * added support for configuring Phase 2 (inner/tunneled) authentication
34 method with wpa_gui-qt4
37 * added support for EAP Sequences in EAP-FAST Phase 2
38 * added support for using TNC with EAP-FAST
39 * added driver_ps3 for the PS3 Linux wireless driver
40 * added support for optional cryptobinding with PEAPv0
41 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
42 allow fallback to full handshake if server rejects PAC-Opaque
43 * added fragmentation support for EAP-TNC
44 * added support for parsing PKCS #8 formatted private keys into the
45 internal TLS implementation (both PKCS #1 RSA key and PKCS #8
46 encapsulated RSA key can now be used)
47 * added option of using faster, but larger, routines in the internal
48 LibTomMath (for internal TLS implementation) to speed up DH and RSA
49 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
50 * fixed race condition between disassociation event and group key
51 handshake to avoid getting stuck in incorrect state [Bug 261]
52 * fixed opportunistic key caching (proactive_key_caching)
55 * removed 'nai' and 'eappsk' network configuration variables that were
56 previously used for configuring user identity and key for EAP-PSK,
57 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
58 replacement for 'nai' (if old configuration used a separate
59 'identity' value, that would now be configured as
60 'anonymous_identity'). 'password' field is now used as the
61 replacement for 'eappsk' (it can also be set using hexstring to
62 present random binary data)
63 * removed '-w' command line parameter (wait for interface to be added,
64 if needed); cleaner way of handling this functionality is to use an
65 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
66 when an interface is added
67 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
68 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
69 indicating when new scan results become available
70 * added new ctrl_iface command, BSS, to allow scan results to be
71 fetched without hitting the message size limits (this command
72 can be used to iterate through the scan results one BSS at the time)
73 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
74 attributes in EAP-SIM Start/Response when using fast reauthentication
75 * fixed EAPOL not to end up in infinite loop when processing dynamic
76 WEP keys with IEEE 802.1X
77 * fixed problems in getting NDIS events from WMI on Windows 2000
80 * added support for Makefile builds to include debug-log-to-a-file
81 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
82 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
83 lengths properly to avoid potential crash caused by invalid messages
84 * added data structure for storing allocated buffers (struct wpabuf);
85 this does not affect wpa_supplicant usage, but many of the APIs
86 changed and various interfaces (e.g., EAP) is not compatible with old
88 * added support for protecting EAP-AKA/Identity messages with
89 AT_CHECKCODE (optional feature in RFC 4187)
90 * added support for protected result indication with AT_RESULT_IND for
91 EAP-SIM and EAP-AKA (phase1="result_ind=1")
92 * added driver_wext workaround for race condition between scanning and
93 association with drivers that take very long time to scan all
94 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
95 using a longer hardcoded timeout for the scan if the driver supports
96 notifications for scan completion (SIOCGIWSCAN event); this helps,
97 e.g., in cases where wpa_supplicant and madwifi driver ended up in
98 loop where the driver did not even try to associate
99 * stop EAPOL timer tick when no timers are in use in order to reduce
100 power consumption (no need to wake up the process once per second)
102 * added support for privilege separation (run only minimal part of
103 wpa_supplicant functionality as root and rest as unprivileged,
104 non-root process); see 'Privilege separation' in README for details;
105 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
107 * changed scan results data structure to include all information
108 elements to make it easier to support new IEs; old get_scan_result()
109 driver_ops is still supported for backwards compatibility (results
110 are converted internally to the new format), but all drivers should
111 start using the new get_scan_results2() to make them more likely to
112 work with new features
113 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
114 application, i.e., it does not require Qt3Support anymore; Windows
115 binary of wpa_gui.exe is now from this directory and only requires
116 QtCore4.dll and QtGui4.dll libraries
117 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
118 available as a separate package to make wpa_gui installation easier:
119 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
120 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
121 only shared key/password authentication is supported in this version
124 * added support for configuring password as NtPasswordHash
125 (16-byte MD4 hash of password) in hash:<32 hex digits> format
126 * added support for fallback from abbreviated TLS handshake to
127 full handshake when using EAP-FAST (e.g., due to an expired
129 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
130 draft (draft-ietf-emu-eap-gpsk-07.txt)
131 * added support for drivers that take care of RSN 4-way handshake
132 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
133 WPA_ALG_PMK in set_key)
134 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
135 .config); this version supports only ap_scan=2 mode and allow the
136 driver to take care of the 4-way handshake
137 * fixed a buffer overflow in parsing TSF from scan results when using
138 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
140 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
141 * fixed an integer overflow issue in the ASN.1 parser used by the
142 (experimental) internal TLS implementation to avoid a potential
144 * fixed a race condition with -W option (wait for a control interface
145 monitor before starting) that could have caused the first messages to
147 * added support for processing TNCC-TNCS-Messages to report
148 recommendation (allow/none/isolate) when using TNC [Bug 243]
151 * added network configuration parameter 'frequency' for setting
152 initial channel for IBSS (adhoc) networks
153 * added experimental IEEE 802.11r/D6.0 support
154 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
155 * updated EAP-PSK to use the IANA-allocated EAP type 47
156 * fixed EAP-PAX key derivation
157 * fixed EAP-PSK bit ordering of the Flags field
158 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
159 tunnelled identity request (previously, the identifier from the outer
160 method was used, not the tunnelled identifier which could be
162 * added support for fragmentation of outer TLS packets during Phase 2
163 of EAP-PEAP/TTLS/FAST
164 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
165 * added support for EAP-FAST authentication with inner methods that
166 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
167 for PAC provisioning)
168 * added support for authenticated EAP-FAST provisioning
169 * added support for configuring maximum number of EAP-FAST PACs to
170 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
171 * added support for storing EAP-FAST PACs in binary format
172 (fast_pac_format=binary in phase1 string)
173 * fixed dbus ctrl_iface to validate message interface before
174 dispatching to avoid a possible segfault [Bug 190]
175 * fixed PeerKey key derivation to use the correct PRF label
176 * updated Windows binary build to link against OpenSSL 0.9.8d and
177 added support for EAP-FAST
178 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
179 draft (draft-ietf-emu-eap-gpsk-04.txt)
180 * fixed EAP-AKA Notification processing to allow Notification to be
181 processed after AKA Challenge response has been sent
182 * updated to use IEEE 802.11w/D2.0 for management frame protection
184 * fixed EAP-TTLS implementation not to crash on use of freed memory
185 if TLS library initialization fails
186 * added support for EAP-TNC (Trusted Network Connect)
187 (this version implements the EAP-TNC method and EAP-TTLS changes
188 needed to run two methods in sequence (IF-T) and the IF-IMC and
189 IF-TNCCS interfaces from TNCC)
192 * added experimental, integrated TLSv1 client implementation with the
193 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
194 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
195 .config); this can be useful, e.g., if the target system does not
196 have a suitable TLS library and a minimal code size is required
197 (total size of this internal TLS/crypto code is bit under 50 kB on
198 x86 and the crypto code is shared by rest of the supplicant so some
199 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
200 * removed STAKey handshake since PeerKey handshake has replaced it in
201 IEEE 802.11ma and there are no known deployments of STAKey
202 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
203 draft (draft-ietf-emu-eap-gpsk-01.txt)
204 * added preliminary implementation of IEEE 802.11w/D1.0 (management
206 (Note: this requires driver support to work properly.)
207 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
208 * fixed Windows named pipes ctrl_iface to not stop listening for
209 commands if client program opens a named pipe and closes it
210 immediately without sending a command
211 * fixed USIM PIN status determination for the case that PIN is not
212 needed (this allows EAP-AKA to be used with USIM cards that do not
214 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
215 be used with cards that do not support file selection based on
217 * added support for matching the subjectAltName of the authentication
218 server certificate against multiple name components (e.g.,
219 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
220 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
221 affects IEEE 802.1X with dynamic WEP keys)
222 * changed ctrl_iface network configuration 'get' operations to not
223 return password/key material; if these fields are requested, "*"
224 will be returned if the password/key is set, but the value of the
225 parameter is not exposed
228 * added support for building Windows version with UNICODE defined
229 (wide-char functions)
230 * driver_ndis: fixed static WEP configuration to avoid race condition
231 issues with some NDIS drivers between association and setting WEP
233 * driver_ndis: added validation for IELength value in scan results to
234 avoid crashes when using buggy NDIS drivers [Bug 165]
235 * fixed Release|Win32 target in the Visual Studio project files
236 (previously, only Debug|Win32 target was set properly)
237 * changed control interface API call wpa_ctrl_pending() to allow it to
238 return -1 on error (e.g., connection lost); control interface clients
239 will need to make sure that they verify that the value is indeed >0
240 when determining whether there are pending messages
241 * added an alternative control interface backend for Windows targets:
242 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
243 control interface mechanism for Windows builds (previously, UDP to
245 * changed ctrl_interface configuration for UNIX domain sockets:
246 - deprecated ctrl_interface_group variable (it may be removed in
248 - allow both directory and group be configured with ctrl_interface
249 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
250 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
251 case when group is not changed
252 * added support for controlling more than one interface per process in
254 * added a workaround for a case where the AP is using unknown address
255 (e.g., MAC address of the wired interface) as the source address for
256 EAPOL-Key frames; previously, that source address was used as the
257 destination for EAPOL-Key frames and in key derivation; now, BSSID is
258 used even if the source address does not match with it
259 (this resolves an interoperability issue with Thomson SpeedTouch 580)
260 * added a workaround for UDP-based control interface (which was used in
261 Windows builds before this release) to prevent packets with forged
262 addresses from being accepted as local control requests
263 * removed ndis_events.cpp and possibility of using external
264 ndis_events.exe; C version (ndis_events.c) is fully functional and
265 there is no desire to maintain two separate versions of this
267 * ndis_events: Changed NDIS event notification design to use WMI to
268 learn the adapter description through Win32_PnPEntity class; this
269 should fix some cases where the adapter name was not recognized
270 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
272 * fixed selection of the first network in ap_scan=2 mode; previously,
273 wpa_supplicant could get stuck in SCANNING state when only the first
274 network for enabled (e.g., after 'wpa_cli select_network 0')
275 * winsvc: added support for configuring ctrl_interface parameters in
276 registry (ctrl_interface string value in
277 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
278 required to enable control interface (previously, this was hardcoded
280 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
281 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
284 * fixed build with CONFIG_STAKEY=y [Bug 143]
285 * added support for doing MLME (IEEE 802.11 management frame
286 processing) in wpa_supplicant when using Devicescape IEEE 802.11
287 stack (wireless-dev.git tree)
288 * added a new network block configuration option, fragment_size, to
289 configure the maximum EAP fragment size
290 * driver_ndis: Disable WZC automatically for the selected interface to
291 avoid conflicts with two programs trying to control the radio; WZC
292 will be re-enabled (if it was enabled originally) when wpa_supplicant
294 * added an experimental TLSv1 client implementation
295 (CONFIG_TLS=internal) that can be used instead of an external TLS
296 library, e.g., to reduce total size requirement on systems that do
297 not include any TLS library by default (this is not yet complete;
298 basic functionality is there, but certificate validation is not yet
300 * added PeerKey handshake implementation for IEEE 802.11e
301 direct link setup (DLS) to replace STAKey handshake
302 * fixed WPA PSK update through ctrl_iface for the case where the old
303 PSK was derived from an ASCII passphrase and the new PSK is set as
304 a raw PSK (hex string)
305 * added new configuration option for identifying which network block
306 was used (id_str in wpa_supplicant.conf; included on
307 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
308 variable in wpa_cli action scripts; in addition WPA_ID variable is
309 set to the current unique identifier that wpa_supplicant assigned
310 automatically for the network and that can be used with
311 GET_NETWORK/SET_NETWORK ctrl_iface commands)
312 * wpa_cli action script is now called only when the connect/disconnect
313 status changes or when associating with a different network
314 * fixed configuration parser not to remove CCMP from group cipher list
315 if WPA-None (adhoc) is used (pairwise=NONE in that case)
316 * fixed integrated NDIS events processing not to hang the process due
317 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
318 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
319 draft-clancy-emu-eap-shared-secret-00.txt)
320 * added Microsoft Visual Studio 2005 solution and project files for
321 build wpa_supplicant for Windows (see vs2005 subdirectory)
322 * eloop_win: fixed unregistration of Windows events
323 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
324 at the end of RSN pre-authentication and added unregistration of
325 a Windows event to avoid getting eloop_win stuck with an invalid
327 * driver_ndis: added support for selecting AP based on BSSID
328 * added new environmental variable for wpa_cli action scripts:
329 WPA_CTRL_DIR is the current control interface directory
330 * driver_ndis: added support for using NDISUIO instead of WinPcap for
331 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
332 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
333 wpa_supplicant without requiring WinPcap; note that using NDISUIO
334 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
335 only one application to open the device
336 * changed NDIS driver naming to only include device GUID, e.g.,
337 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
338 specific \Device\NPF_ prefix before the GUID; the prefix is still
339 allowed for backwards compatibility, but it is not required anymore
340 when specifying the interface
341 * driver_ndis: re-initialize driver interface is the adapter is removed
342 and re-inserted [Bug 159]
343 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
344 big endian hosts [Bug 146]
347 * fixed EAP-GTC response to include correct user identity when run as
348 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
349 * driver_ndis: Fixed encryption mode configuration for unencrypted
350 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
351 refused to associate with open networks) [Bug 106]
352 * driver_ndis: use BSSID OID polling to detect when IBSS network is
353 formed even when ndis_events code is included since some NDIS drivers
354 do not generate media connect events in IBSS mode
355 * config_winreg: allow global ctrl_interface parameter to be configured
357 * config_winreg: added support for saving configuration data into
359 * added support for controlling network device operational state
360 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
361 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
362 that can use this information)
363 * driver_wext: added support for WE-21 change to SSID configuration
364 * driver_wext: fixed privacy configuration for static WEP keys mode
366 * added an optional driver_ops callback for MLME-SETPROTECTION.request
368 * added support for EAP-SAKE (no EAP method number allocated yet, so
369 this is using the same experimental type 255 as EAP-PSK)
370 * added support for dynamically loading EAP methods (.so files) instead
371 of requiring them to be statically linked in; this is disabled by
372 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
376 * do not try to use USIM APDUs when initializing PC/SC for SIM card
377 access for a network that has not enabled EAP-AKA
378 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
379 v0.5.1 due to the new support for expanded EAP types)
380 * added support for generating EAP Expanded Nak
381 * try to fetch scan results once before requesting new scan when
382 starting up in ap_scan=1 mode (this can speed up initial association
383 a lot with, e.g., madwifi-ng driver)
384 * added support for receiving EAPOL frames from a Linux bridge
385 interface (-bbr0 on command line)
386 * fixed EAPOL re-authentication for sessions that used PMKSA caching
387 * changed EAP method registration to use a dynamic list of methods
388 instead of a static list generated at build time
389 * fixed PMKSA cache deinitialization not to use freed memory when
390 removing PMKSA entries
391 * fixed a memory leak in EAP-TTLS re-authentication
392 * reject WPA/WPA2 message 3/4 if it does not include any valid
394 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
395 if the driver does not support SIOCSIWAUTH
398 * driver_test: added better support for multiple APs and STAs by using
399 a directory with sockets that include MAC address for each device in
400 the name (driver_param=test_dir=/tmp/test)
401 * added support for EAP expanded type (vendor specific EAP methods)
402 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
403 option can be changed if needed
404 * wpa_cli/wpa_gui: skip non-socket files in control directory when
405 using UNIX domain sockets; this avoids selecting an incorrect
406 interface (e.g., a PID file could be in this directory, even though
407 use of this directory for something else than socket files is not
409 * fixed TLS library deinitialization after RSN pre-authentication not
410 to disable TLS library for normal authentication
411 * driver_wext: Remove null-termination from SSID length if the driver
412 used it; some Linux drivers do this and they were causing problems in
413 wpa_supplicant not finding matching configuration block. This change
414 would break a case where the SSID actually ends in '\0', but that is
415 not likely to happen in real use.
416 * fixed PMKSA cache processing not to trigger deauthentication if the
417 current PMKSA cache entry is replaced with a valid new entry
418 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
419 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
422 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
423 * added experimental STAKey handshake implementation for IEEE 802.11e
424 direct link setup (DLS); note: this is disabled by default in both
425 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
427 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
428 decrypt AT_ENCR_DATA attributes correctly
429 * fixed EAP-AKA to allow resynchronization within the same session
430 * made code closer to ANSI C89 standard to make it easier to port to
431 other C libraries and compilers
432 * started moving operating system or C library specific functions into
433 wrapper functions defined in os.h and implemented in os_*.c to make
435 * wpa_supplicant can now be built with Microsoft Visual C++
436 (e.g., with the freely available Toolkit 2003 version or Visual
437 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
438 example makefile for nmake
439 * added support for using Windows registry for command line parameters
440 (CONFIG_MAIN=main_winsvc) and configuration data
441 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
442 contents; this version can be run both as a Windows service and as a
443 normal application; 'wpasvc.exe app' to start as applicant,
444 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
445 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
447 * made it possible to link ndis_events.exe functionality into
448 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
449 * added better support for multiple control interface backends
450 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
451 * fixed PC/SC code to use correct length for GSM AUTH command buffer
452 and to not use pioRecvPci with SCardTransmit() calls; these were not
453 causing visible problems with pcsc-lite, but Windows Winscard.dll
454 refused the previously used parameters; this fixes EAP-SIM and
455 EAP-AKA authentication using SIM/USIM card under Windows
456 * added new event loop implementation for Windows using
457 WaitForMultipleObject() instead of select() in order to allow waiting
458 for non-socket objects; this can be selected with
459 CONFIG_ELOOP=eloop_win in .config
460 * added support for selecting l2_packet implementation in .config
461 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
462 winpcap, freebsd, none)
463 * added new l2_packet implementation for WinPcap
464 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
465 reduce latency in EAPOL receive processing from about 100 ms to about
467 * added support for EAP-FAST key derivation using other ciphers than
468 RC4-128-SHA for authentication and AES128-SHA for provisioning
469 * added support for configuring CA certificate as DER file and as a
471 * fixed private key configuration as configuration blob and added
472 support for using PKCS#12 as a blob
473 * tls_gnutls: added support for using PKCS#12 files; added support for
475 * added support for loading trusted CA certificates from Windows
476 certificate store: ca_cert="cert_store://<name>", where <name> is
477 likely CA (Intermediate CA certificates) or ROOT (root certificates)
478 * added C version of ndis_events.cpp and made it possible to build this
479 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
480 easily on cross-compilation builds
481 * added wpasvc.exe into Windows binary release; this is an alternative
482 version of wpa_supplicant.exe with configuration backend using
483 Windows registry and with the entry point designed to run as a
485 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
486 wpasvc.exe and removed this additional tool from the Windows binary
487 release since it is not needed anymore
488 * load winscard.dll functions dynamically when building with MinGW
489 since MinGW does not yet include winscard library
491 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
492 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
493 and WinPcap to receive frames sent to PAE group address
494 * disable EAP state machine when IEEE 802.1X authentication is not used
495 in order to get rid of bogus "EAP failed" messages
496 * fixed OpenSSL error reporting to go through all pending errors to
497 avoid confusing reports of old errors being reported at later point
499 * fixed configuration file updating to not write empty variables
500 (e.g., proto or key_mgmt) that the file parser would not accept
501 * fixed ADD_NETWORK ctrl_iface command to use the same default values
502 for variables as empty network definitions read from config file
504 * fixed EAP state machine to not discard EAP-Failure messages in many
505 cases (e.g., during TLS handshake)
506 * fixed a infinite loop in private key reading if the configured file
507 cannot be parsed successfully
508 * driver_madwifi: added support for madwifi-ng
509 * wpa_gui: do not display password/PSK field contents
510 * wpa_gui: added CA certificate configuration
511 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
512 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
513 the new AP is using different WPA/RSN IE
514 * use longer timeout for IEEE 802.11 association to avoid problems with
515 drivers that may take more than five second to associate
518 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
519 RSN IE, but WPA IE would match with wpa_supplicant configuration
520 * added support for named configuration blobs in order to avoid having
521 to use file system for external files (e.g., certificates);
522 variables can be set to "blob://<blob name>" instead of file path to
523 use a named blob; supported fields: pac_file, client_cert,
525 * fixed RSN pre-authentication (it was broken in the clean up of WPA
526 state machine interface in v0.4.5)
527 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
528 sure the driver configures broadcast decryption correctly
529 * added ca_path (and ca_path2) configuration variables that can be used
530 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
531 system-wide trusted CA list
532 * added support for starting wpa_supplicant without a configuration
533 file (-C argument must be used to set ctrl_interface parameter for
534 this case; in addition, -p argument can be used to provide
535 driver_param; these new arguments can also be used with a
536 configuration to override the values from the configuration)
537 * added global control interface that can be optionally used for adding
538 and removing network interfaces dynamically (-g command line argument
539 for both wpa_supplicant and wpa_cli) without having to restart
540 wpa_supplicant process
542 - try to save configuration whenever something is modified
543 - added WEP key configuration
544 - added possibility to edit the current network configuration
545 * driver_ndis: fixed driver polling not to increase frequency on each
546 received EAPOL frame due to incorrectly cancelled timeout
547 * added simple configuration file examples (in examples subdirectory)
548 * fixed driver_wext.c to filter wireless events based on ifindex to
549 avoid interfaces receiving events from other interfaces
550 * delay sending initial EAPOL-Start couple of seconds to speed up
551 authentication for the most common case of Authenticator starting
552 EAP authentication immediately after association
555 * added a workaround for clearing keys with ndiswrapper to allow
556 roaming from WPA enabled AP to plaintext one
557 * added docbook documentation (doc/docbook) that can be used to
558 generate, e.g., man pages
559 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
560 PF_PACKET in order to prepare for network devices that do not use
561 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
562 * use receipt of EAPOL-Key frame as a lower layer success indication
563 for EAP state machine to allow recovery from dropped EAP-Success
565 * cleaned up internal EAPOL frame processing by not including link
566 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
567 header is added only when transmitted the frame; this makes it easier
568 to use wpa_supplicant on link layers that use different header than
570 * updated EAP-PSK to use draft 9 by default since this can now be
571 tested with hostapd; removed support for draft 3, including
572 server_nai configuration option from network blocks
573 * driver_wired: add PAE address to the multicast address list in order
574 to be able to receive EAPOL frames with drivers that do not include
575 these multicast addresses by default
576 * driver_wext: add support for WE-19
577 * added support for multiple configuration backends (CONFIG_BACKEND
578 option); currently, only 'file' is supported (i.e., the format used
579 in wpa_supplicant.conf)
580 * added support for updating configuration ('wpa_cli save_config');
581 this is disabled by default and can be enabled with global
582 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
583 and wpa_gui to store the configuration changes in a permanent store
584 * added GET_NETWORK ctrl_iface command
585 (e.g., 'wpa_cli get_network 0 ssid')
588 * replaced OpenSSL patch for EAP-FAST support
589 (openssl-tls-extensions.patch) with a more generic and correct
590 patch (the new patch is not compatible with the previous one, so the
591 OpenSSL library will need to be patched with the new patch in order
592 to be able to build wpa_supplicant with EAP-FAST support)
593 * added support for using Windows certificate store (through CryptoAPI)
594 for client certificate and private key operations (EAP-TLS)
595 (see wpa_supplicant.conf for more information on how to configure
596 this with private_key)
597 * ported wpa_gui to Windows
598 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
599 built with the open source version of the Qt4 for Windows
600 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
601 with drivers that do not support WPA
602 * ndis_events: fixed Windows 2000 support
603 * added support for enabling/disabling networks from the list of all
604 configured networks ('wpa_cli enable_network <network id>' and
605 'wpa_cli disable_network <network id>')
606 * added support for adding and removing network from the current
607 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
608 <network id>'); added networks are disabled by default and they can
609 be enabled with enable_network command once the configuration is done
610 for the new network; note: configuration file is not yet updated, so
611 these new networks are lost when wpa_supplicant is restarted
612 * added support for setting network configuration parameters through
613 the control interface, for example:
614 wpa_cli set_network 0 ssid "\"my network\""
615 * fixed parsing of strings that include both " and # within double
616 quoted area (e.g., "start"#end")
617 * added EAP workaround for PEAP session resumption: allow outer,
618 i.e., not tunneled, EAP-Success to terminate session since; this can
619 be disabled with eap_workaround=0
620 (this was allowed for PEAPv1 before, but now it is also allowed for
621 PEAPv0 since at least one RADIUS authentication server seems to be
622 doing this for PEAPv0, too)
623 * wpa_gui: added preliminary support for adding new networks to the
624 wpa_supplicant configuration (double click on the scan results to
625 open network configuration)
628 * removed interface for external EAPOL/EAP supplicant (e.g.,
629 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
630 anymore and is unlikely to be used by anyone
631 * driver_ndis: fixed WinPcap 3.0 support
632 * fixed build with CONFIG_DNET_PCAP=y on Linux
633 * l2_packet: moved different implementations into separate files
637 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
638 (note: ipw2100-1.1.0 is likely to require an update to work with
640 * added support for using ap_scan=2 mode with multiple network blocks;
641 wpa_supplicant will go through the networks one by one until the
642 driver reports a successful association; this uses the same order for
643 networks as scan_ssid=1 scans, i.e., the priority field is ignored
644 and the network block order in the file is used instead
645 * fixed a potential issue in RSN pre-authentication ending up using
646 freed memory if pre-authentication times out
647 * added support for matching alternative subject name extensions of the
648 authentication server certificate; new configuration variables
649 altsubject_match and altsubject_match2
650 * driver_ndis: added support for IEEE 802.1X authentication with wired
652 * added support for querying private key password (EAP-TLS) through the
653 control interface (wpa_cli/wpa_gui) if one is not included in the
655 * driver_broadcom: fixed couple of memory leaks in scan result
657 * EAP-PAX is now registered as EAP type 46
658 * fixed EAP-PAX MAC calculation
659 * fixed EAP-PAX CK and ICK key derivation
660 * added support for using password with EAP-PAX (as an alternative to
661 entering key with eappsk); SHA-1 hash of the password will be used as
663 * added support for arbitrary driver interface parameters through the
664 configuration file with a new driver_param field; this adds a new
665 driver_ops function set_param()
666 * added possibility to override l2_packet module with driver interface
667 API (new send_eapol handler); this can be used to implement driver
668 specific TX/RX functions for EAPOL frames
669 * fixed ctrl_interface_group processing for the case where gid is
670 entered as a number, not group name
671 * driver_test: added support for testing hostapd with wpa_supplicant
672 by using test driver interface without any kernel drivers or network
676 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
677 packets to be encrypted; this was apparently broken by the changed
678 ioctl order in v0.4.0
679 * driver_madwifi: added preliminary support for compiling against 'BSD'
680 branch of madwifi CVS tree
681 * added support for EAP-MSCHAPv2 password retries within the same EAP
682 authentication session
683 * added support for password changes with EAP-MSCHAPv2 (used when the
684 password has expired)
685 * added support for reading additional certificates from PKCS#12 files
686 and adding them to the certificate chain
687 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
689 * fixed a possible double free in EAP-TTLS fast-reauthentication when
690 identity or password is entered through control interface
691 * display EAP Notification messages to user through control interface
692 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
693 * added GUI version of wpa_cli, wpa_gui; this is not build
694 automatically with 'make'; use 'make wpa_gui' to build (this requires
695 Qt development tools)
696 * added 'disconnect' command to control interface for setting
697 wpa_supplicant in state where it will not associate before
698 'reassociate' command has been used
699 * added support for selecting a network from the list of all configured
700 networks ('wpa_cli select_network <network id>'; this disabled all
701 other networks; to re-enable, 'wpa_cli select_network any')
702 * added support for getting scan results through control interface
703 * added EAP workaround for PEAPv1 session resumption: allow outer,
704 i.e., not tunneled, EAP-Success to terminate session since; this can
705 be disabled with eap_workaround=0
707 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
708 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
709 used to reduce the size of the wpa_supplicant considerably if
710 debugging code is not needed
711 * fixed EAPOL-Key validation to drop packets with invalid Key Data
712 Length; such frames could have crashed wpa_supplicant due to buffer
714 * added support for wired authentication (IEEE 802.1X on wired
715 Ethernet); driver interface 'wired'
716 * obsoleted set_wpa() handler in the driver interface API (it can be
717 replaced by moving enable/disable functionality into init()/deinit())
718 (calls to set_wpa() are still present for backwards compatibility,
719 but they may be removed in the future)
720 * driver_madwifi: fixed association in plaintext mode
721 * modified the EAP workaround that accepts EAP-Success with incorrect
722 Identifier to be even less strict about verification in order to
723 interoperate with some authentication servers
724 * added support for sending TLS alerts
725 * added support for 'any' SSID wildcard; if ssid is not configured or
726 is set to an empty string, any SSID will be accepted for non-WPA AP
727 * added support for asking PIN (for SIM) from frontends (e.g.,
728 wpa_cli); if a PIN is needed, but not included in the configuration
729 file, a control interface request is sent and EAP processing is
730 delayed until the PIN is available
731 * added support for using external devices (e.g., a smartcard) for
732 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
733 new wpa_supplicant.conf variables:
734 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
735 - network: engine, engine_id, key_id
736 * added experimental support for EAP-PAX
737 * added monitor mode for wpa_cli (-a<path to a program to run>) that
738 allows external commands (e.g., shell scripts) to be run based on
739 wpa_supplicant events, e.g., when authentication has been completed
740 and data connection is ready; other related wpa_cli arguments:
741 -B (run in background), -P (write PID file); wpa_supplicant has a new
742 command line argument (-W) that can be used to make it wait until a
743 control interface command is received in order to avoid missing
745 * added support for opportunistic WPA2 PMKSA key caching (disabled by
746 default, can be enabled with proactive_key_caching=1)
747 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
748 Authenticator rejects PMKSA caching attempt and the driver is not
749 using assoc_info events
750 * added -P<pid file> argument for wpa_supplicant to write the current
751 process id into a file
753 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
754 * added new phase1 option parameter, include_tls_length=1, to force
755 wpa_supplicant to add TLS Message Length field to all TLS messages
756 even if the packet is not fragmented; this may be needed with some
757 authentication servers
758 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
759 using drivers that take care of AP selection (e.g., when using
761 * fixed reprocessing of pending request after ctrl_iface requests for
762 identity/password/otp
763 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
764 EAP-PEAP and EAP-TTLS
765 * all drivers using driver_wext: set interface up and select Managed
766 mode when starting wpa_supplicant; set interface down when exiting
767 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
768 ipw2100 and ipw2200; please note that this also changed the
769 configuration variable in .config to CONFIG_DRIVER_IPW
772 * fixed a busy loop introduced in v0.3.5 for scan result processing
773 when no matching AP is found
776 * added a workaround for an interoperability issue with a Cisco AP
778 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
779 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
780 retransmission of dropped frames)
781 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
782 (e.g., segfault when processing EAPOL-Key frames)
783 * fixed EAP workaround and fast reauthentication configuration for
784 RSN pre-authentication; previously these were disabled and
785 pre-authentication would fail if the used authentication server
786 requires EAP workarounds
787 * added support for blacklisting APs that fail or timeout
788 authentication in ap_scan=1 mode so that all APs are tried in cases
789 where the ones with strongest signal level are failing authentication
790 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
791 authentication attempt
792 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
793 in the previous authentication (previously, only Phase 1 success was
797 * added preliminary support for IBSS (ad-hoc) mode configuration
798 (mode=1 in network block); this included a new key_mgmt mode
799 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
800 key management; see wpa_supplicant.conf for more details and an
801 example on how to configure this (note: this is currently implemented
802 only for driver_hostapd.c, but the changes should be trivial to add
803 in associate() handler for other drivers, too (assuming the driver
805 * added preliminary port for native Windows (i.e., no cygwin) using
809 * added optional support for GNU Readline and History Libraries for
810 wpa_cli (CONFIG_READLINE)
811 * cleaned up EAP state machine <-> method interface and number of
812 small problems with error case processing not terminating on
813 EAP-Failure but waiting for timeout
814 * added couple of workarounds for interoperability issues with a
815 Cisco AP when using WPA2
816 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
817 Note: This requires a patch for openssl to add support for TLS
818 extensions and number of workarounds for operations without
819 certificates. Proof of concept type of experimental patch is
820 included in openssl-tls-extensions.patch.
823 * fixed private key loading for cases where passphrase is not set
824 * fixed Windows/cygwin L2 packet handler freeing; previous version
825 could cause a segfault when RSN pre-authentication was completed
826 * added support for PMKSA caching with drivers that generate RSN IEs
827 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
828 but similar code can be easily added to driver_ndiswrapper.c once
829 ndiswrapper gets full support for RSN PMKSA caching
830 * improved recovery from PMKID mismatches by requesting full EAP
831 authentication in case of failed PMKSA caching attempt
832 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
833 (this requires that ndis_events is ran while wpa_supplicant is
835 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
836 * added support for driver interfaces to replace the interface name
837 based on driver/OS specific mapping, e.g., in case of driver_ndis,
838 this allows the beginning of the adapter description to be used as
840 * added support for CR+LF (Windows-style) line ends in configuration
842 * driver_ndis: enable radio before starting scanning, disable radio
844 * modified association event handler to set portEnabled = FALSE before
845 clearing port Valid in order to reset EAP state machine and avoid
846 problems with new authentication getting ignored because of state
847 machines ending up in AUTHENTICATED/SUCCESS state based on old
849 * added support for driver events to add PMKID candidates in order to
850 allow drivers to give priority to most likely roaming candidates
851 * driver_hostap: moved PrivacyInvoked configuration to associate()
852 function so that this will not be set for plaintext connections
853 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
854 interface can distinguish plaintext and IEEE 802.1X (no WPA)
856 * fixed static WEP key configuration to use broadcast/default type for
857 all keys (previously, the default TX key was configured as pairwise/
859 * driver_ndis: added legacy WPA capability detection for non-WPA2
861 * added support for setting static WEP keys for IEEE 802.1X without
862 dynamic WEP keying (eapol_flags=0)
865 * added support for reading PKCS#12 (PFX) files (as a replacement for
866 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
867 * fixed compilation with CONFIG_PCSC=y
868 * added new ap_scan mode, ap_scan=2, for drivers that take care of
869 association, but need to be configured with security policy and SSID,
870 e.g., ndiswrapper and NDIS driver; this mode should allow such
871 drivers to work with hidden SSIDs and optimized roaming; when
872 ap_scan=2 is used, only the first network block in the configuration
873 file is used and this configuration should have explicit security
874 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
875 group, proto variables
876 * added experimental port of wpa_supplicant for Windows
877 - driver_ndis.c driver interface (NDIS OIDs)
878 - currently, this requires cygwin and WinPcap
879 - small utility, win_if_list, can be used to get interface name
880 * control interface can now be removed at build time; add
881 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
882 * optional Xsupplicant interface can now be removed at build time;
883 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
884 * added auth_alg to driver interface associate() parameters to make it
885 easier for drivers to configure authentication algorithm as part of
888 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
889 * driver_broadcom: added new driver interface for Broadcom wl.o driver
890 (a generic driver for Broadcom IEEE 802.11a/g cards)
891 * wpa_cli: fixed parsing of -p <path> command line argument
892 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
893 ACK, not tunneled EAP-Success (of which only the first byte was
894 actually send due to a bug in previous code); this seems to
895 interoperate with most RADIUS servers that implements PEAPv1
896 * PEAPv1: added support for terminating PEAP authentication on tunneled
897 EAP-Success message; this can be configured by adding
898 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
899 (some RADIUS servers require this whereas others require a tunneled
901 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
902 the old label for key derivation; previously, the default was 1,
903 but it looks like most existing PEAPv1 implementations use the old
904 label which is thus more suitable default option
905 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
906 * fixed parsing of wep_tx_keyidx
907 * added support for configuring list of allowed Phase 2 EAP types
908 (for both EAP-PEAP and EAP-TTLS) instead of only one type
909 * added support for configuring IEEE 802.11 authentication algorithm
910 (auth_alg; mainly for using Shared Key authentication with static
912 * added support for EAP-AKA (with UMTS SIM)
913 * fixed couple of errors in PCSC handling that could have caused
914 random-looking errors for EAP-SIM
915 * added support for EAP-SIM pseudonyms and fast re-authentication
916 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
918 * added support for EAP-SIM with two challanges
919 (phase1="sim_min_num_chal=3" can be used to require three challenges)
920 * added support for configuring DH/DSA parameters for an ephemeral DH
921 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
922 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
923 and optional DH key exchange to achieve forward secracy with RSA keys
924 * added support for matching subject of the authentication server
925 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
926 configuration variables subject_match and subject_match2
927 * changed SSID configuration in driver_wext.c (used by many driver
928 interfaces) to use ssid_len+1 as the length for SSID since some Linux
930 * fixed couple of unaligned reads in scan result parsing to fix WPA
931 connection on some platforms (e.g., ARM)
932 * added driver interface for Intel ipw2100 driver
933 * added support for LEAP with WPA
934 * added support for larger scan results report (old limit was 4 kB of
935 data, i.e., about 35 or so APs) when using Linux wireless extensions
937 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
938 only if there is a PMKSA cache entry for the current AP
939 * fixed error handling for case where reading of scan results fails:
940 must schedule a new scan or wpa_supplicant will remain waiting
942 * changed debug output to remove shared password/key material by
943 default; all key information can be included with -K command line
944 argument to match the previous behavior
945 * added support for timestamping debug log messages (disabled by
946 default, can be enabled with -t command line argument)
947 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
948 if keys are not configured to be used; this fixes IEEE 802.1X mode
949 with drivers that use this information to configure whether Privacy
950 bit can be in Beacon frames (e.g., ndiswrapper)
951 * avoid clearing driver keys if no keys have been configured since last
952 key clear request; this seems to improve reliability of group key
953 handshake for ndiswrapper & NDIS driver which seems to be suffering
954 of some kind of timing issue when the keys are cleared again after
956 * changed driver interface API:
957 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
958 version is being used (now, this is set to 2; previously, it was
960 - pass pointer to private data structure to all calls
961 - the new API is not backwards compatible; all in-tree driver
962 interfaces has been converted to the new API
963 * added support for controlling multiple interfaces (radios) per
964 wpa_supplicant process; each interface needs to be listed on the
965 command line (-c, -i, -D arguments) with -N as a separator
966 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
967 * added a workaround for EAP servers that incorrectly use same Id for
968 sequential EAP packets
969 * changed libpcap/libdnet configuration to use .config variable,
970 CONFIG_DNET_PCAP, instead of requiring Makefile modification
971 * improved downgrade attack detection in IE verification of msg 3/4:
972 verify both WPA and RSN IEs, if present, not only the selected one;
973 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
974 Probe Response frame, and RSN is enabled in wpa_supplicant
976 * fixed WPA msg 3/4 processing to allow Key Data field contain other
977 IEs than just one WPA IE
978 * added support for FreeBSD and driver interface for the BSD net80211
979 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
980 required kernel mods have not yet been committed
981 * made EAP workarounds configurable; enabled by default, can be
982 disabled with network block option eap_workaround=0
984 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
985 * resolved couple of interoperability issues with EAP-PEAPv1 and
986 Phase 2 (inner EAP) fragment reassembly
987 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
988 AP is using non-zero key index for the unicast key and key index zero
989 for the broadcast key
990 * driver_hostap: fixed IEEE 802.1X WEP key updates and
991 re-authentication by allowing unencrypted EAPOL frames when not using
993 * added a new driver interface, 'wext', which uses only standard,
994 driver independent functionality in Linux wireless extensions;
995 currently, this can be used only for non-WPA IEEE 802.1X mode, but
996 eventually, this is to be extended to support full WPA/WPA2 once
997 Linux wireless extensions get support for this
998 * added support for mode in which the driver is responsible for AP
999 scanning and selection; this is disabled by default and can be
1000 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
1001 this mode can be used, e.g., with generic 'wext' driver interface to
1002 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
1003 supporting wireless extensions.
1004 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
1005 operation with an AP that does not include SSID in the Beacon frames)
1006 * added support for new EAP authentication methods:
1007 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
1008 * added support for asking one-time-passwords from frontends (e.g.,
1009 wpa_cli); this 'otp' command works otherwise like 'password' command,
1010 but the password is used only once and the frontend will be asked for
1011 a new password whenever a request from authenticator requires a
1012 password; this can be used with both EAP-OTP and EAP-GTC
1013 * changed wpa_cli to automatically re-establish connection so that it
1014 does not need to be re-started when wpa_supplicant is terminated and
1016 * improved user data (identity/password/otp) requests through
1017 frontends: process pending EAPOL packets after getting new
1018 information so that full authentication does not need to be
1019 restarted; in addition, send pending requests again whenever a new
1020 frontend is attached
1021 * changed control frontends to use a new directory for socket files to
1022 make it easier for wpa_cli to automatically select between interfaces
1023 and to provide access control for the control interface;
1024 wpa_supplicant.conf: ctrl_interface is now a path
1025 (/var/run/wpa_supplicant is the recommended path) and
1026 ctrl_interface_group can be used to select which group gets access to
1027 the control interface;
1028 wpa_cli: by default, try to connect to the first interface available
1029 in /var/run/wpa_supplicant; this path can be overriden with -p option
1030 and an interface can be selected with -i option (i.e., in most common
1031 cases, wpa_cli does not need to get any arguments)
1032 * added support for LEAP
1033 * added driver interface for Linux ndiswrapper
1034 * added priority option for network blocks in the configuration file;
1035 this allows networks to be grouped based on priority (the scan
1036 results are searched for matches with network blocks in this order)
1039 * sort scan results to improve AP selection
1040 * fixed control interface socket removal for some error cases
1041 * improved scan requesting and authentication timeout
1042 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1044 * PEAP version can now be forced with phase1="peapver=<ver>"
1045 (mostly for testing; by default, the highest version supported by
1046 both the Supplicant and Authentication Server is selected
1048 * added support for madwifi driver (Atheros ar521x)
1049 * added a workaround for cases where AP sets Install Tx/Rx bit for
1050 WPA Group Key messages when pairwise keys are used (without this,
1051 the Group Key would be used for Tx and the AP would drop frames
1053 * added GSM SIM/USIM interface for GSM authentication algorithm for
1054 EAP-SIM; this requires pcsc-lite
1055 * added support for ATMEL AT76C5XXx driver
1056 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1057 does not include key data in the EAPOL-Key frame (i.e., part of
1058 EAP keying material is used as data encryption key)
1059 * added support for using plaintext and static WEP networks
1063 * added support for new EAP authentication methods:
1064 EAP-TTLS/EAP-MD5-Challenge
1066 EAP-TTLS/EAP-MSCHAPv2
1074 EAP-PEAP/MD5-Challenge
1076 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1077 * added support for anonymous identity (to be used when identity is
1078 sent in plaintext; real identity will be used within TLS protected
1079 tunnel (e.g., with EAP-TTLS)
1080 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1081 * added support for requesting identity and password information using
1082 control interface; in other words, the password for EAP-PEAP or
1083 EAP-TTLS does not need to be included in the configuration file since
1084 a frontand (e.g., wpa_cli) can ask it from the user
1085 * improved RSN pre-authentication to use a candidate list and process
1086 all candidates from each scan; not only one per scan
1087 * fixed RSN IE and WPA IE capabilities field parsing
1088 * ignore Tx bit in GTK IE when Pairwise keys are used
1089 * avoid making new scan requests during IEEE 802.1X negotiation
1090 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1091 with TLS support (this replaces the included implementation with
1092 library code to save about 8 kB since the library code is needed
1094 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1095 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1098 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1100 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1101 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1102 - EAP-MD5 (cannot be used with WPA-RADIUS)
1103 [draft-ietf-eap-rfc2284bis-09.txt]
1104 - EAP-TLS [RFC 2716]
1105 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1106 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1107 [draft-kamath-pppext-eap-mschapv2-00.txt]
1108 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1109 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1110 - new configuration file options: eap, identity, password, ca_cert,
1111 client_cert, privatekey, private_key_passwd
1112 - Xsupplicant is not required anymore, but it can be used by
1113 disabling the internal IEEE 802.1X Supplicant with -e command line
1115 - this code is not included in the default build; Makefile need to
1116 be edited for this (uncomment lines for selected functionality)
1117 - EAP-TLS and EAP-PEAP require openssl libraries
1118 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1119 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1120 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1121 EAPOL-Key frames instead of WPA key handshakes)
1122 * added support for IEEE 802.11i/RSN (WPA2)
1123 - improved PTK Key Handshake
1124 - PMKSA caching, pre-authentication
1125 * fixed wpa_supplicant to ignore possible extra data after WPA
1126 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1127 TPTK' error from message 3 of 4-Way Handshake in case the AP
1128 includes extra data after the EAPOL-Key)
1129 * added interface for external programs (frontends) to control
1131 - CLI example (wpa_cli) with interactive mode and command line
1133 - replaced SIGUSR1 status/statistics with the new control interface
1134 * made some feature compile time configurable
1135 - .config file for make
1136 - driver interfaces (hostap, hermes, ..)
1137 - EAPOL/EAP functions
1140 * Initial version of wpa_supplicant
