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)
23 * added support for SHA-256 as X.509 certificate digest when using the
24 internal X.509/TLSv1 implementation
25 * updated management frame protection to use IEEE 802.11w/D6.0
26 * added support for using SHA256-based stronger key derivation for WPA2
28 * fixed FT (IEEE 802.11r) authentication after a failed association to
30 * added support for configuring Phase 2 (inner/tunneled) authentication
31 method with wpa_gui-qt4
34 * added support for EAP Sequences in EAP-FAST Phase 2
35 * added support for using TNC with EAP-FAST
36 * added driver_ps3 for the PS3 Linux wireless driver
37 * added support for optional cryptobinding with PEAPv0
38 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
39 allow fallback to full handshake if server rejects PAC-Opaque
40 * added fragmentation support for EAP-TNC
41 * added support for parsing PKCS #8 formatted private keys into the
42 internal TLS implementation (both PKCS #1 RSA key and PKCS #8
43 encapsulated RSA key can now be used)
44 * added option of using faster, but larger, routines in the internal
45 LibTomMath (for internal TLS implementation) to speed up DH and RSA
46 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
47 * fixed race condition between disassociation event and group key
48 handshake to avoid getting stuck in incorrect state [Bug 261]
49 * fixed opportunistic key caching (proactive_key_caching)
52 * removed 'nai' and 'eappsk' network configuration variables that were
53 previously used for configuring user identity and key for EAP-PSK,
54 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
55 replacement for 'nai' (if old configuration used a separate
56 'identity' value, that would now be configured as
57 'anonymous_identity'). 'password' field is now used as the
58 replacement for 'eappsk' (it can also be set using hexstring to
59 present random binary data)
60 * removed '-w' command line parameter (wait for interface to be added,
61 if needed); cleaner way of handling this functionality is to use an
62 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
63 when an interface is added
64 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
65 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
66 indicating when new scan results become available
67 * added new ctrl_iface command, BSS, to allow scan results to be
68 fetched without hitting the message size limits (this command
69 can be used to iterate through the scan results one BSS at the time)
70 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
71 attributes in EAP-SIM Start/Response when using fast reauthentication
72 * fixed EAPOL not to end up in infinite loop when processing dynamic
73 WEP keys with IEEE 802.1X
74 * fixed problems in getting NDIS events from WMI on Windows 2000
77 * added support for Makefile builds to include debug-log-to-a-file
78 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
79 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
80 lengths properly to avoid potential crash caused by invalid messages
81 * added data structure for storing allocated buffers (struct wpabuf);
82 this does not affect wpa_supplicant usage, but many of the APIs
83 changed and various interfaces (e.g., EAP) is not compatible with old
85 * added support for protecting EAP-AKA/Identity messages with
86 AT_CHECKCODE (optional feature in RFC 4187)
87 * added support for protected result indication with AT_RESULT_IND for
88 EAP-SIM and EAP-AKA (phase1="result_ind=1")
89 * added driver_wext workaround for race condition between scanning and
90 association with drivers that take very long time to scan all
91 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
92 using a longer hardcoded timeout for the scan if the driver supports
93 notifications for scan completion (SIOCGIWSCAN event); this helps,
94 e.g., in cases where wpa_supplicant and madwifi driver ended up in
95 loop where the driver did not even try to associate
96 * stop EAPOL timer tick when no timers are in use in order to reduce
97 power consumption (no need to wake up the process once per second)
99 * added support for privilege separation (run only minimal part of
100 wpa_supplicant functionality as root and rest as unprivileged,
101 non-root process); see 'Privilege separation' in README for details;
102 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
104 * changed scan results data structure to include all information
105 elements to make it easier to support new IEs; old get_scan_result()
106 driver_ops is still supported for backwards compatibility (results
107 are converted internally to the new format), but all drivers should
108 start using the new get_scan_results2() to make them more likely to
109 work with new features
110 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
111 application, i.e., it does not require Qt3Support anymore; Windows
112 binary of wpa_gui.exe is now from this directory and only requires
113 QtCore4.dll and QtGui4.dll libraries
114 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
115 available as a separate package to make wpa_gui installation easier:
116 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
117 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
118 only shared key/password authentication is supported in this version
121 * added support for configuring password as NtPasswordHash
122 (16-byte MD4 hash of password) in hash:<32 hex digits> format
123 * added support for fallback from abbreviated TLS handshake to
124 full handshake when using EAP-FAST (e.g., due to an expired
126 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
127 draft (draft-ietf-emu-eap-gpsk-07.txt)
128 * added support for drivers that take care of RSN 4-way handshake
129 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
130 WPA_ALG_PMK in set_key)
131 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
132 .config); this version supports only ap_scan=2 mode and allow the
133 driver to take care of the 4-way handshake
134 * fixed a buffer overflow in parsing TSF from scan results when using
135 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
137 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
138 * fixed an integer overflow issue in the ASN.1 parser used by the
139 (experimental) internal TLS implementation to avoid a potential
141 * fixed a race condition with -W option (wait for a control interface
142 monitor before starting) that could have caused the first messages to
144 * added support for processing TNCC-TNCS-Messages to report
145 recommendation (allow/none/isolate) when using TNC [Bug 243]
148 * added network configuration parameter 'frequency' for setting
149 initial channel for IBSS (adhoc) networks
150 * added experimental IEEE 802.11r/D6.0 support
151 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
152 * updated EAP-PSK to use the IANA-allocated EAP type 47
153 * fixed EAP-PAX key derivation
154 * fixed EAP-PSK bit ordering of the Flags field
155 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
156 tunnelled identity request (previously, the identifier from the outer
157 method was used, not the tunnelled identifier which could be
159 * added support for fragmentation of outer TLS packets during Phase 2
160 of EAP-PEAP/TTLS/FAST
161 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
162 * added support for EAP-FAST authentication with inner methods that
163 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
164 for PAC provisioning)
165 * added support for authenticated EAP-FAST provisioning
166 * added support for configuring maximum number of EAP-FAST PACs to
167 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
168 * added support for storing EAP-FAST PACs in binary format
169 (fast_pac_format=binary in phase1 string)
170 * fixed dbus ctrl_iface to validate message interface before
171 dispatching to avoid a possible segfault [Bug 190]
172 * fixed PeerKey key derivation to use the correct PRF label
173 * updated Windows binary build to link against OpenSSL 0.9.8d and
174 added support for EAP-FAST
175 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
176 draft (draft-ietf-emu-eap-gpsk-04.txt)
177 * fixed EAP-AKA Notification processing to allow Notification to be
178 processed after AKA Challenge response has been sent
179 * updated to use IEEE 802.11w/D2.0 for management frame protection
181 * fixed EAP-TTLS implementation not to crash on use of freed memory
182 if TLS library initialization fails
183 * added support for EAP-TNC (Trusted Network Connect)
184 (this version implements the EAP-TNC method and EAP-TTLS changes
185 needed to run two methods in sequence (IF-T) and the IF-IMC and
186 IF-TNCCS interfaces from TNCC)
189 * added experimental, integrated TLSv1 client implementation with the
190 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
191 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
192 .config); this can be useful, e.g., if the target system does not
193 have a suitable TLS library and a minimal code size is required
194 (total size of this internal TLS/crypto code is bit under 50 kB on
195 x86 and the crypto code is shared by rest of the supplicant so some
196 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
197 * removed STAKey handshake since PeerKey handshake has replaced it in
198 IEEE 802.11ma and there are no known deployments of STAKey
199 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
200 draft (draft-ietf-emu-eap-gpsk-01.txt)
201 * added preliminary implementation of IEEE 802.11w/D1.0 (management
203 (Note: this requires driver support to work properly.)
204 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
205 * fixed Windows named pipes ctrl_iface to not stop listening for
206 commands if client program opens a named pipe and closes it
207 immediately without sending a command
208 * fixed USIM PIN status determination for the case that PIN is not
209 needed (this allows EAP-AKA to be used with USIM cards that do not
211 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
212 be used with cards that do not support file selection based on
214 * added support for matching the subjectAltName of the authentication
215 server certificate against multiple name components (e.g.,
216 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
217 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
218 affects IEEE 802.1X with dynamic WEP keys)
219 * changed ctrl_iface network configuration 'get' operations to not
220 return password/key material; if these fields are requested, "*"
221 will be returned if the password/key is set, but the value of the
222 parameter is not exposed
225 * added support for building Windows version with UNICODE defined
226 (wide-char functions)
227 * driver_ndis: fixed static WEP configuration to avoid race condition
228 issues with some NDIS drivers between association and setting WEP
230 * driver_ndis: added validation for IELength value in scan results to
231 avoid crashes when using buggy NDIS drivers [Bug 165]
232 * fixed Release|Win32 target in the Visual Studio project files
233 (previously, only Debug|Win32 target was set properly)
234 * changed control interface API call wpa_ctrl_pending() to allow it to
235 return -1 on error (e.g., connection lost); control interface clients
236 will need to make sure that they verify that the value is indeed >0
237 when determining whether there are pending messages
238 * added an alternative control interface backend for Windows targets:
239 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
240 control interface mechanism for Windows builds (previously, UDP to
242 * changed ctrl_interface configuration for UNIX domain sockets:
243 - deprecated ctrl_interface_group variable (it may be removed in
245 - allow both directory and group be configured with ctrl_interface
246 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
247 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
248 case when group is not changed
249 * added support for controlling more than one interface per process in
251 * added a workaround for a case where the AP is using unknown address
252 (e.g., MAC address of the wired interface) as the source address for
253 EAPOL-Key frames; previously, that source address was used as the
254 destination for EAPOL-Key frames and in key derivation; now, BSSID is
255 used even if the source address does not match with it
256 (this resolves an interoperability issue with Thomson SpeedTouch 580)
257 * added a workaround for UDP-based control interface (which was used in
258 Windows builds before this release) to prevent packets with forged
259 addresses from being accepted as local control requests
260 * removed ndis_events.cpp and possibility of using external
261 ndis_events.exe; C version (ndis_events.c) is fully functional and
262 there is no desire to maintain two separate versions of this
264 * ndis_events: Changed NDIS event notification design to use WMI to
265 learn the adapter description through Win32_PnPEntity class; this
266 should fix some cases where the adapter name was not recognized
267 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
269 * fixed selection of the first network in ap_scan=2 mode; previously,
270 wpa_supplicant could get stuck in SCANNING state when only the first
271 network for enabled (e.g., after 'wpa_cli select_network 0')
272 * winsvc: added support for configuring ctrl_interface parameters in
273 registry (ctrl_interface string value in
274 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
275 required to enable control interface (previously, this was hardcoded
277 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
278 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
281 * fixed build with CONFIG_STAKEY=y [Bug 143]
282 * added support for doing MLME (IEEE 802.11 management frame
283 processing) in wpa_supplicant when using Devicescape IEEE 802.11
284 stack (wireless-dev.git tree)
285 * added a new network block configuration option, fragment_size, to
286 configure the maximum EAP fragment size
287 * driver_ndis: Disable WZC automatically for the selected interface to
288 avoid conflicts with two programs trying to control the radio; WZC
289 will be re-enabled (if it was enabled originally) when wpa_supplicant
291 * added an experimental TLSv1 client implementation
292 (CONFIG_TLS=internal) that can be used instead of an external TLS
293 library, e.g., to reduce total size requirement on systems that do
294 not include any TLS library by default (this is not yet complete;
295 basic functionality is there, but certificate validation is not yet
297 * added PeerKey handshake implementation for IEEE 802.11e
298 direct link setup (DLS) to replace STAKey handshake
299 * fixed WPA PSK update through ctrl_iface for the case where the old
300 PSK was derived from an ASCII passphrase and the new PSK is set as
301 a raw PSK (hex string)
302 * added new configuration option for identifying which network block
303 was used (id_str in wpa_supplicant.conf; included on
304 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
305 variable in wpa_cli action scripts; in addition WPA_ID variable is
306 set to the current unique identifier that wpa_supplicant assigned
307 automatically for the network and that can be used with
308 GET_NETWORK/SET_NETWORK ctrl_iface commands)
309 * wpa_cli action script is now called only when the connect/disconnect
310 status changes or when associating with a different network
311 * fixed configuration parser not to remove CCMP from group cipher list
312 if WPA-None (adhoc) is used (pairwise=NONE in that case)
313 * fixed integrated NDIS events processing not to hang the process due
314 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
315 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
316 draft-clancy-emu-eap-shared-secret-00.txt)
317 * added Microsoft Visual Studio 2005 solution and project files for
318 build wpa_supplicant for Windows (see vs2005 subdirectory)
319 * eloop_win: fixed unregistration of Windows events
320 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
321 at the end of RSN pre-authentication and added unregistration of
322 a Windows event to avoid getting eloop_win stuck with an invalid
324 * driver_ndis: added support for selecting AP based on BSSID
325 * added new environmental variable for wpa_cli action scripts:
326 WPA_CTRL_DIR is the current control interface directory
327 * driver_ndis: added support for using NDISUIO instead of WinPcap for
328 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
329 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
330 wpa_supplicant without requiring WinPcap; note that using NDISUIO
331 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
332 only one application to open the device
333 * changed NDIS driver naming to only include device GUID, e.g.,
334 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
335 specific \Device\NPF_ prefix before the GUID; the prefix is still
336 allowed for backwards compatibility, but it is not required anymore
337 when specifying the interface
338 * driver_ndis: re-initialize driver interface is the adapter is removed
339 and re-inserted [Bug 159]
340 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
341 big endian hosts [Bug 146]
344 * fixed EAP-GTC response to include correct user identity when run as
345 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
346 * driver_ndis: Fixed encryption mode configuration for unencrypted
347 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
348 refused to associate with open networks) [Bug 106]
349 * driver_ndis: use BSSID OID polling to detect when IBSS network is
350 formed even when ndis_events code is included since some NDIS drivers
351 do not generate media connect events in IBSS mode
352 * config_winreg: allow global ctrl_interface parameter to be configured
354 * config_winreg: added support for saving configuration data into
356 * added support for controlling network device operational state
357 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
358 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
359 that can use this information)
360 * driver_wext: added support for WE-21 change to SSID configuration
361 * driver_wext: fixed privacy configuration for static WEP keys mode
363 * added an optional driver_ops callback for MLME-SETPROTECTION.request
365 * added support for EAP-SAKE (no EAP method number allocated yet, so
366 this is using the same experimental type 255 as EAP-PSK)
367 * added support for dynamically loading EAP methods (.so files) instead
368 of requiring them to be statically linked in; this is disabled by
369 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
373 * do not try to use USIM APDUs when initializing PC/SC for SIM card
374 access for a network that has not enabled EAP-AKA
375 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
376 v0.5.1 due to the new support for expanded EAP types)
377 * added support for generating EAP Expanded Nak
378 * try to fetch scan results once before requesting new scan when
379 starting up in ap_scan=1 mode (this can speed up initial association
380 a lot with, e.g., madwifi-ng driver)
381 * added support for receiving EAPOL frames from a Linux bridge
382 interface (-bbr0 on command line)
383 * fixed EAPOL re-authentication for sessions that used PMKSA caching
384 * changed EAP method registration to use a dynamic list of methods
385 instead of a static list generated at build time
386 * fixed PMKSA cache deinitialization not to use freed memory when
387 removing PMKSA entries
388 * fixed a memory leak in EAP-TTLS re-authentication
389 * reject WPA/WPA2 message 3/4 if it does not include any valid
391 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
392 if the driver does not support SIOCSIWAUTH
395 * driver_test: added better support for multiple APs and STAs by using
396 a directory with sockets that include MAC address for each device in
397 the name (driver_param=test_dir=/tmp/test)
398 * added support for EAP expanded type (vendor specific EAP methods)
399 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
400 option can be changed if needed
401 * wpa_cli/wpa_gui: skip non-socket files in control directory when
402 using UNIX domain sockets; this avoids selecting an incorrect
403 interface (e.g., a PID file could be in this directory, even though
404 use of this directory for something else than socket files is not
406 * fixed TLS library deinitialization after RSN pre-authentication not
407 to disable TLS library for normal authentication
408 * driver_wext: Remove null-termination from SSID length if the driver
409 used it; some Linux drivers do this and they were causing problems in
410 wpa_supplicant not finding matching configuration block. This change
411 would break a case where the SSID actually ends in '\0', but that is
412 not likely to happen in real use.
413 * fixed PMKSA cache processing not to trigger deauthentication if the
414 current PMKSA cache entry is replaced with a valid new entry
415 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
416 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
419 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
420 * added experimental STAKey handshake implementation for IEEE 802.11e
421 direct link setup (DLS); note: this is disabled by default in both
422 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
424 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
425 decrypt AT_ENCR_DATA attributes correctly
426 * fixed EAP-AKA to allow resynchronization within the same session
427 * made code closer to ANSI C89 standard to make it easier to port to
428 other C libraries and compilers
429 * started moving operating system or C library specific functions into
430 wrapper functions defined in os.h and implemented in os_*.c to make
432 * wpa_supplicant can now be built with Microsoft Visual C++
433 (e.g., with the freely available Toolkit 2003 version or Visual
434 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
435 example makefile for nmake
436 * added support for using Windows registry for command line parameters
437 (CONFIG_MAIN=main_winsvc) and configuration data
438 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
439 contents; this version can be run both as a Windows service and as a
440 normal application; 'wpasvc.exe app' to start as applicant,
441 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
442 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
444 * made it possible to link ndis_events.exe functionality into
445 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
446 * added better support for multiple control interface backends
447 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
448 * fixed PC/SC code to use correct length for GSM AUTH command buffer
449 and to not use pioRecvPci with SCardTransmit() calls; these were not
450 causing visible problems with pcsc-lite, but Windows Winscard.dll
451 refused the previously used parameters; this fixes EAP-SIM and
452 EAP-AKA authentication using SIM/USIM card under Windows
453 * added new event loop implementation for Windows using
454 WaitForMultipleObject() instead of select() in order to allow waiting
455 for non-socket objects; this can be selected with
456 CONFIG_ELOOP=eloop_win in .config
457 * added support for selecting l2_packet implementation in .config
458 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
459 winpcap, freebsd, none)
460 * added new l2_packet implementation for WinPcap
461 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
462 reduce latency in EAPOL receive processing from about 100 ms to about
464 * added support for EAP-FAST key derivation using other ciphers than
465 RC4-128-SHA for authentication and AES128-SHA for provisioning
466 * added support for configuring CA certificate as DER file and as a
468 * fixed private key configuration as configuration blob and added
469 support for using PKCS#12 as a blob
470 * tls_gnutls: added support for using PKCS#12 files; added support for
472 * added support for loading trusted CA certificates from Windows
473 certificate store: ca_cert="cert_store://<name>", where <name> is
474 likely CA (Intermediate CA certificates) or ROOT (root certificates)
475 * added C version of ndis_events.cpp and made it possible to build this
476 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
477 easily on cross-compilation builds
478 * added wpasvc.exe into Windows binary release; this is an alternative
479 version of wpa_supplicant.exe with configuration backend using
480 Windows registry and with the entry point designed to run as a
482 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
483 wpasvc.exe and removed this additional tool from the Windows binary
484 release since it is not needed anymore
485 * load winscard.dll functions dynamically when building with MinGW
486 since MinGW does not yet include winscard library
488 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
489 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
490 and WinPcap to receive frames sent to PAE group address
491 * disable EAP state machine when IEEE 802.1X authentication is not used
492 in order to get rid of bogus "EAP failed" messages
493 * fixed OpenSSL error reporting to go through all pending errors to
494 avoid confusing reports of old errors being reported at later point
496 * fixed configuration file updating to not write empty variables
497 (e.g., proto or key_mgmt) that the file parser would not accept
498 * fixed ADD_NETWORK ctrl_iface command to use the same default values
499 for variables as empty network definitions read from config file
501 * fixed EAP state machine to not discard EAP-Failure messages in many
502 cases (e.g., during TLS handshake)
503 * fixed a infinite loop in private key reading if the configured file
504 cannot be parsed successfully
505 * driver_madwifi: added support for madwifi-ng
506 * wpa_gui: do not display password/PSK field contents
507 * wpa_gui: added CA certificate configuration
508 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
509 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
510 the new AP is using different WPA/RSN IE
511 * use longer timeout for IEEE 802.11 association to avoid problems with
512 drivers that may take more than five second to associate
515 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
516 RSN IE, but WPA IE would match with wpa_supplicant configuration
517 * added support for named configuration blobs in order to avoid having
518 to use file system for external files (e.g., certificates);
519 variables can be set to "blob://<blob name>" instead of file path to
520 use a named blob; supported fields: pac_file, client_cert,
522 * fixed RSN pre-authentication (it was broken in the clean up of WPA
523 state machine interface in v0.4.5)
524 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
525 sure the driver configures broadcast decryption correctly
526 * added ca_path (and ca_path2) configuration variables that can be used
527 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
528 system-wide trusted CA list
529 * added support for starting wpa_supplicant without a configuration
530 file (-C argument must be used to set ctrl_interface parameter for
531 this case; in addition, -p argument can be used to provide
532 driver_param; these new arguments can also be used with a
533 configuration to override the values from the configuration)
534 * added global control interface that can be optionally used for adding
535 and removing network interfaces dynamically (-g command line argument
536 for both wpa_supplicant and wpa_cli) without having to restart
537 wpa_supplicant process
539 - try to save configuration whenever something is modified
540 - added WEP key configuration
541 - added possibility to edit the current network configuration
542 * driver_ndis: fixed driver polling not to increase frequency on each
543 received EAPOL frame due to incorrectly cancelled timeout
544 * added simple configuration file examples (in examples subdirectory)
545 * fixed driver_wext.c to filter wireless events based on ifindex to
546 avoid interfaces receiving events from other interfaces
547 * delay sending initial EAPOL-Start couple of seconds to speed up
548 authentication for the most common case of Authenticator starting
549 EAP authentication immediately after association
552 * added a workaround for clearing keys with ndiswrapper to allow
553 roaming from WPA enabled AP to plaintext one
554 * added docbook documentation (doc/docbook) that can be used to
555 generate, e.g., man pages
556 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
557 PF_PACKET in order to prepare for network devices that do not use
558 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
559 * use receipt of EAPOL-Key frame as a lower layer success indication
560 for EAP state machine to allow recovery from dropped EAP-Success
562 * cleaned up internal EAPOL frame processing by not including link
563 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
564 header is added only when transmitted the frame; this makes it easier
565 to use wpa_supplicant on link layers that use different header than
567 * updated EAP-PSK to use draft 9 by default since this can now be
568 tested with hostapd; removed support for draft 3, including
569 server_nai configuration option from network blocks
570 * driver_wired: add PAE address to the multicast address list in order
571 to be able to receive EAPOL frames with drivers that do not include
572 these multicast addresses by default
573 * driver_wext: add support for WE-19
574 * added support for multiple configuration backends (CONFIG_BACKEND
575 option); currently, only 'file' is supported (i.e., the format used
576 in wpa_supplicant.conf)
577 * added support for updating configuration ('wpa_cli save_config');
578 this is disabled by default and can be enabled with global
579 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
580 and wpa_gui to store the configuration changes in a permanent store
581 * added GET_NETWORK ctrl_iface command
582 (e.g., 'wpa_cli get_network 0 ssid')
585 * replaced OpenSSL patch for EAP-FAST support
586 (openssl-tls-extensions.patch) with a more generic and correct
587 patch (the new patch is not compatible with the previous one, so the
588 OpenSSL library will need to be patched with the new patch in order
589 to be able to build wpa_supplicant with EAP-FAST support)
590 * added support for using Windows certificate store (through CryptoAPI)
591 for client certificate and private key operations (EAP-TLS)
592 (see wpa_supplicant.conf for more information on how to configure
593 this with private_key)
594 * ported wpa_gui to Windows
595 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
596 built with the open source version of the Qt4 for Windows
597 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
598 with drivers that do not support WPA
599 * ndis_events: fixed Windows 2000 support
600 * added support for enabling/disabling networks from the list of all
601 configured networks ('wpa_cli enable_network <network id>' and
602 'wpa_cli disable_network <network id>')
603 * added support for adding and removing network from the current
604 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
605 <network id>'); added networks are disabled by default and they can
606 be enabled with enable_network command once the configuration is done
607 for the new network; note: configuration file is not yet updated, so
608 these new networks are lost when wpa_supplicant is restarted
609 * added support for setting network configuration parameters through
610 the control interface, for example:
611 wpa_cli set_network 0 ssid "\"my network\""
612 * fixed parsing of strings that include both " and # within double
613 quoted area (e.g., "start"#end")
614 * added EAP workaround for PEAP session resumption: allow outer,
615 i.e., not tunneled, EAP-Success to terminate session since; this can
616 be disabled with eap_workaround=0
617 (this was allowed for PEAPv1 before, but now it is also allowed for
618 PEAPv0 since at least one RADIUS authentication server seems to be
619 doing this for PEAPv0, too)
620 * wpa_gui: added preliminary support for adding new networks to the
621 wpa_supplicant configuration (double click on the scan results to
622 open network configuration)
625 * removed interface for external EAPOL/EAP supplicant (e.g.,
626 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
627 anymore and is unlikely to be used by anyone
628 * driver_ndis: fixed WinPcap 3.0 support
629 * fixed build with CONFIG_DNET_PCAP=y on Linux
630 * l2_packet: moved different implementations into separate files
634 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
635 (note: ipw2100-1.1.0 is likely to require an update to work with
637 * added support for using ap_scan=2 mode with multiple network blocks;
638 wpa_supplicant will go through the networks one by one until the
639 driver reports a successful association; this uses the same order for
640 networks as scan_ssid=1 scans, i.e., the priority field is ignored
641 and the network block order in the file is used instead
642 * fixed a potential issue in RSN pre-authentication ending up using
643 freed memory if pre-authentication times out
644 * added support for matching alternative subject name extensions of the
645 authentication server certificate; new configuration variables
646 altsubject_match and altsubject_match2
647 * driver_ndis: added support for IEEE 802.1X authentication with wired
649 * added support for querying private key password (EAP-TLS) through the
650 control interface (wpa_cli/wpa_gui) if one is not included in the
652 * driver_broadcom: fixed couple of memory leaks in scan result
654 * EAP-PAX is now registered as EAP type 46
655 * fixed EAP-PAX MAC calculation
656 * fixed EAP-PAX CK and ICK key derivation
657 * added support for using password with EAP-PAX (as an alternative to
658 entering key with eappsk); SHA-1 hash of the password will be used as
660 * added support for arbitrary driver interface parameters through the
661 configuration file with a new driver_param field; this adds a new
662 driver_ops function set_param()
663 * added possibility to override l2_packet module with driver interface
664 API (new send_eapol handler); this can be used to implement driver
665 specific TX/RX functions for EAPOL frames
666 * fixed ctrl_interface_group processing for the case where gid is
667 entered as a number, not group name
668 * driver_test: added support for testing hostapd with wpa_supplicant
669 by using test driver interface without any kernel drivers or network
673 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
674 packets to be encrypted; this was apparently broken by the changed
675 ioctl order in v0.4.0
676 * driver_madwifi: added preliminary support for compiling against 'BSD'
677 branch of madwifi CVS tree
678 * added support for EAP-MSCHAPv2 password retries within the same EAP
679 authentication session
680 * added support for password changes with EAP-MSCHAPv2 (used when the
681 password has expired)
682 * added support for reading additional certificates from PKCS#12 files
683 and adding them to the certificate chain
684 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
686 * fixed a possible double free in EAP-TTLS fast-reauthentication when
687 identity or password is entered through control interface
688 * display EAP Notification messages to user through control interface
689 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
690 * added GUI version of wpa_cli, wpa_gui; this is not build
691 automatically with 'make'; use 'make wpa_gui' to build (this requires
692 Qt development tools)
693 * added 'disconnect' command to control interface for setting
694 wpa_supplicant in state where it will not associate before
695 'reassociate' command has been used
696 * added support for selecting a network from the list of all configured
697 networks ('wpa_cli select_network <network id>'; this disabled all
698 other networks; to re-enable, 'wpa_cli select_network any')
699 * added support for getting scan results through control interface
700 * added EAP workaround for PEAPv1 session resumption: allow outer,
701 i.e., not tunneled, EAP-Success to terminate session since; this can
702 be disabled with eap_workaround=0
704 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
705 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
706 used to reduce the size of the wpa_supplicant considerably if
707 debugging code is not needed
708 * fixed EAPOL-Key validation to drop packets with invalid Key Data
709 Length; such frames could have crashed wpa_supplicant due to buffer
711 * added support for wired authentication (IEEE 802.1X on wired
712 Ethernet); driver interface 'wired'
713 * obsoleted set_wpa() handler in the driver interface API (it can be
714 replaced by moving enable/disable functionality into init()/deinit())
715 (calls to set_wpa() are still present for backwards compatibility,
716 but they may be removed in the future)
717 * driver_madwifi: fixed association in plaintext mode
718 * modified the EAP workaround that accepts EAP-Success with incorrect
719 Identifier to be even less strict about verification in order to
720 interoperate with some authentication servers
721 * added support for sending TLS alerts
722 * added support for 'any' SSID wildcard; if ssid is not configured or
723 is set to an empty string, any SSID will be accepted for non-WPA AP
724 * added support for asking PIN (for SIM) from frontends (e.g.,
725 wpa_cli); if a PIN is needed, but not included in the configuration
726 file, a control interface request is sent and EAP processing is
727 delayed until the PIN is available
728 * added support for using external devices (e.g., a smartcard) for
729 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
730 new wpa_supplicant.conf variables:
731 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
732 - network: engine, engine_id, key_id
733 * added experimental support for EAP-PAX
734 * added monitor mode for wpa_cli (-a<path to a program to run>) that
735 allows external commands (e.g., shell scripts) to be run based on
736 wpa_supplicant events, e.g., when authentication has been completed
737 and data connection is ready; other related wpa_cli arguments:
738 -B (run in background), -P (write PID file); wpa_supplicant has a new
739 command line argument (-W) that can be used to make it wait until a
740 control interface command is received in order to avoid missing
742 * added support for opportunistic WPA2 PMKSA key caching (disabled by
743 default, can be enabled with proactive_key_caching=1)
744 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
745 Authenticator rejects PMKSA caching attempt and the driver is not
746 using assoc_info events
747 * added -P<pid file> argument for wpa_supplicant to write the current
748 process id into a file
750 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
751 * added new phase1 option parameter, include_tls_length=1, to force
752 wpa_supplicant to add TLS Message Length field to all TLS messages
753 even if the packet is not fragmented; this may be needed with some
754 authentication servers
755 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
756 using drivers that take care of AP selection (e.g., when using
758 * fixed reprocessing of pending request after ctrl_iface requests for
759 identity/password/otp
760 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
761 EAP-PEAP and EAP-TTLS
762 * all drivers using driver_wext: set interface up and select Managed
763 mode when starting wpa_supplicant; set interface down when exiting
764 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
765 ipw2100 and ipw2200; please note that this also changed the
766 configuration variable in .config to CONFIG_DRIVER_IPW
769 * fixed a busy loop introduced in v0.3.5 for scan result processing
770 when no matching AP is found
773 * added a workaround for an interoperability issue with a Cisco AP
775 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
776 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
777 retransmission of dropped frames)
778 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
779 (e.g., segfault when processing EAPOL-Key frames)
780 * fixed EAP workaround and fast reauthentication configuration for
781 RSN pre-authentication; previously these were disabled and
782 pre-authentication would fail if the used authentication server
783 requires EAP workarounds
784 * added support for blacklisting APs that fail or timeout
785 authentication in ap_scan=1 mode so that all APs are tried in cases
786 where the ones with strongest signal level are failing authentication
787 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
788 authentication attempt
789 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
790 in the previous authentication (previously, only Phase 1 success was
794 * added preliminary support for IBSS (ad-hoc) mode configuration
795 (mode=1 in network block); this included a new key_mgmt mode
796 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
797 key management; see wpa_supplicant.conf for more details and an
798 example on how to configure this (note: this is currently implemented
799 only for driver_hostapd.c, but the changes should be trivial to add
800 in associate() handler for other drivers, too (assuming the driver
802 * added preliminary port for native Windows (i.e., no cygwin) using
806 * added optional support for GNU Readline and History Libraries for
807 wpa_cli (CONFIG_READLINE)
808 * cleaned up EAP state machine <-> method interface and number of
809 small problems with error case processing not terminating on
810 EAP-Failure but waiting for timeout
811 * added couple of workarounds for interoperability issues with a
812 Cisco AP when using WPA2
813 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
814 Note: This requires a patch for openssl to add support for TLS
815 extensions and number of workarounds for operations without
816 certificates. Proof of concept type of experimental patch is
817 included in openssl-tls-extensions.patch.
820 * fixed private key loading for cases where passphrase is not set
821 * fixed Windows/cygwin L2 packet handler freeing; previous version
822 could cause a segfault when RSN pre-authentication was completed
823 * added support for PMKSA caching with drivers that generate RSN IEs
824 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
825 but similar code can be easily added to driver_ndiswrapper.c once
826 ndiswrapper gets full support for RSN PMKSA caching
827 * improved recovery from PMKID mismatches by requesting full EAP
828 authentication in case of failed PMKSA caching attempt
829 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
830 (this requires that ndis_events is ran while wpa_supplicant is
832 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
833 * added support for driver interfaces to replace the interface name
834 based on driver/OS specific mapping, e.g., in case of driver_ndis,
835 this allows the beginning of the adapter description to be used as
837 * added support for CR+LF (Windows-style) line ends in configuration
839 * driver_ndis: enable radio before starting scanning, disable radio
841 * modified association event handler to set portEnabled = FALSE before
842 clearing port Valid in order to reset EAP state machine and avoid
843 problems with new authentication getting ignored because of state
844 machines ending up in AUTHENTICATED/SUCCESS state based on old
846 * added support for driver events to add PMKID candidates in order to
847 allow drivers to give priority to most likely roaming candidates
848 * driver_hostap: moved PrivacyInvoked configuration to associate()
849 function so that this will not be set for plaintext connections
850 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
851 interface can distinguish plaintext and IEEE 802.1X (no WPA)
853 * fixed static WEP key configuration to use broadcast/default type for
854 all keys (previously, the default TX key was configured as pairwise/
856 * driver_ndis: added legacy WPA capability detection for non-WPA2
858 * added support for setting static WEP keys for IEEE 802.1X without
859 dynamic WEP keying (eapol_flags=0)
862 * added support for reading PKCS#12 (PFX) files (as a replacement for
863 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
864 * fixed compilation with CONFIG_PCSC=y
865 * added new ap_scan mode, ap_scan=2, for drivers that take care of
866 association, but need to be configured with security policy and SSID,
867 e.g., ndiswrapper and NDIS driver; this mode should allow such
868 drivers to work with hidden SSIDs and optimized roaming; when
869 ap_scan=2 is used, only the first network block in the configuration
870 file is used and this configuration should have explicit security
871 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
872 group, proto variables
873 * added experimental port of wpa_supplicant for Windows
874 - driver_ndis.c driver interface (NDIS OIDs)
875 - currently, this requires cygwin and WinPcap
876 - small utility, win_if_list, can be used to get interface name
877 * control interface can now be removed at build time; add
878 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
879 * optional Xsupplicant interface can now be removed at build time;
880 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
881 * added auth_alg to driver interface associate() parameters to make it
882 easier for drivers to configure authentication algorithm as part of
885 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
886 * driver_broadcom: added new driver interface for Broadcom wl.o driver
887 (a generic driver for Broadcom IEEE 802.11a/g cards)
888 * wpa_cli: fixed parsing of -p <path> command line argument
889 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
890 ACK, not tunneled EAP-Success (of which only the first byte was
891 actually send due to a bug in previous code); this seems to
892 interoperate with most RADIUS servers that implements PEAPv1
893 * PEAPv1: added support for terminating PEAP authentication on tunneled
894 EAP-Success message; this can be configured by adding
895 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
896 (some RADIUS servers require this whereas others require a tunneled
898 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
899 the old label for key derivation; previously, the default was 1,
900 but it looks like most existing PEAPv1 implementations use the old
901 label which is thus more suitable default option
902 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
903 * fixed parsing of wep_tx_keyidx
904 * added support for configuring list of allowed Phase 2 EAP types
905 (for both EAP-PEAP and EAP-TTLS) instead of only one type
906 * added support for configuring IEEE 802.11 authentication algorithm
907 (auth_alg; mainly for using Shared Key authentication with static
909 * added support for EAP-AKA (with UMTS SIM)
910 * fixed couple of errors in PCSC handling that could have caused
911 random-looking errors for EAP-SIM
912 * added support for EAP-SIM pseudonyms and fast re-authentication
913 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
915 * added support for EAP-SIM with two challanges
916 (phase1="sim_min_num_chal=3" can be used to require three challenges)
917 * added support for configuring DH/DSA parameters for an ephemeral DH
918 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
919 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
920 and optional DH key exchange to achieve forward secracy with RSA keys
921 * added support for matching subject of the authentication server
922 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
923 configuration variables subject_match and subject_match2
924 * changed SSID configuration in driver_wext.c (used by many driver
925 interfaces) to use ssid_len+1 as the length for SSID since some Linux
927 * fixed couple of unaligned reads in scan result parsing to fix WPA
928 connection on some platforms (e.g., ARM)
929 * added driver interface for Intel ipw2100 driver
930 * added support for LEAP with WPA
931 * added support for larger scan results report (old limit was 4 kB of
932 data, i.e., about 35 or so APs) when using Linux wireless extensions
934 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
935 only if there is a PMKSA cache entry for the current AP
936 * fixed error handling for case where reading of scan results fails:
937 must schedule a new scan or wpa_supplicant will remain waiting
939 * changed debug output to remove shared password/key material by
940 default; all key information can be included with -K command line
941 argument to match the previous behavior
942 * added support for timestamping debug log messages (disabled by
943 default, can be enabled with -t command line argument)
944 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
945 if keys are not configured to be used; this fixes IEEE 802.1X mode
946 with drivers that use this information to configure whether Privacy
947 bit can be in Beacon frames (e.g., ndiswrapper)
948 * avoid clearing driver keys if no keys have been configured since last
949 key clear request; this seems to improve reliability of group key
950 handshake for ndiswrapper & NDIS driver which seems to be suffering
951 of some kind of timing issue when the keys are cleared again after
953 * changed driver interface API:
954 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
955 version is being used (now, this is set to 2; previously, it was
957 - pass pointer to private data structure to all calls
958 - the new API is not backwards compatible; all in-tree driver
959 interfaces has been converted to the new API
960 * added support for controlling multiple interfaces (radios) per
961 wpa_supplicant process; each interface needs to be listed on the
962 command line (-c, -i, -D arguments) with -N as a separator
963 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
964 * added a workaround for EAP servers that incorrectly use same Id for
965 sequential EAP packets
966 * changed libpcap/libdnet configuration to use .config variable,
967 CONFIG_DNET_PCAP, instead of requiring Makefile modification
968 * improved downgrade attack detection in IE verification of msg 3/4:
969 verify both WPA and RSN IEs, if present, not only the selected one;
970 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
971 Probe Response frame, and RSN is enabled in wpa_supplicant
973 * fixed WPA msg 3/4 processing to allow Key Data field contain other
974 IEs than just one WPA IE
975 * added support for FreeBSD and driver interface for the BSD net80211
976 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
977 required kernel mods have not yet been committed
978 * made EAP workarounds configurable; enabled by default, can be
979 disabled with network block option eap_workaround=0
981 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
982 * resolved couple of interoperability issues with EAP-PEAPv1 and
983 Phase 2 (inner EAP) fragment reassembly
984 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
985 AP is using non-zero key index for the unicast key and key index zero
986 for the broadcast key
987 * driver_hostap: fixed IEEE 802.1X WEP key updates and
988 re-authentication by allowing unencrypted EAPOL frames when not using
990 * added a new driver interface, 'wext', which uses only standard,
991 driver independent functionality in Linux wireless extensions;
992 currently, this can be used only for non-WPA IEEE 802.1X mode, but
993 eventually, this is to be extended to support full WPA/WPA2 once
994 Linux wireless extensions get support for this
995 * added support for mode in which the driver is responsible for AP
996 scanning and selection; this is disabled by default and can be
997 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
998 this mode can be used, e.g., with generic 'wext' driver interface to
999 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
1000 supporting wireless extensions.
1001 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
1002 operation with an AP that does not include SSID in the Beacon frames)
1003 * added support for new EAP authentication methods:
1004 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
1005 * added support for asking one-time-passwords from frontends (e.g.,
1006 wpa_cli); this 'otp' command works otherwise like 'password' command,
1007 but the password is used only once and the frontend will be asked for
1008 a new password whenever a request from authenticator requires a
1009 password; this can be used with both EAP-OTP and EAP-GTC
1010 * changed wpa_cli to automatically re-establish connection so that it
1011 does not need to be re-started when wpa_supplicant is terminated and
1013 * improved user data (identity/password/otp) requests through
1014 frontends: process pending EAPOL packets after getting new
1015 information so that full authentication does not need to be
1016 restarted; in addition, send pending requests again whenever a new
1017 frontend is attached
1018 * changed control frontends to use a new directory for socket files to
1019 make it easier for wpa_cli to automatically select between interfaces
1020 and to provide access control for the control interface;
1021 wpa_supplicant.conf: ctrl_interface is now a path
1022 (/var/run/wpa_supplicant is the recommended path) and
1023 ctrl_interface_group can be used to select which group gets access to
1024 the control interface;
1025 wpa_cli: by default, try to connect to the first interface available
1026 in /var/run/wpa_supplicant; this path can be overriden with -p option
1027 and an interface can be selected with -i option (i.e., in most common
1028 cases, wpa_cli does not need to get any arguments)
1029 * added support for LEAP
1030 * added driver interface for Linux ndiswrapper
1031 * added priority option for network blocks in the configuration file;
1032 this allows networks to be grouped based on priority (the scan
1033 results are searched for matches with network blocks in this order)
1036 * sort scan results to improve AP selection
1037 * fixed control interface socket removal for some error cases
1038 * improved scan requesting and authentication timeout
1039 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1041 * PEAP version can now be forced with phase1="peapver=<ver>"
1042 (mostly for testing; by default, the highest version supported by
1043 both the Supplicant and Authentication Server is selected
1045 * added support for madwifi driver (Atheros ar521x)
1046 * added a workaround for cases where AP sets Install Tx/Rx bit for
1047 WPA Group Key messages when pairwise keys are used (without this,
1048 the Group Key would be used for Tx and the AP would drop frames
1050 * added GSM SIM/USIM interface for GSM authentication algorithm for
1051 EAP-SIM; this requires pcsc-lite
1052 * added support for ATMEL AT76C5XXx driver
1053 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1054 does not include key data in the EAPOL-Key frame (i.e., part of
1055 EAP keying material is used as data encryption key)
1056 * added support for using plaintext and static WEP networks
1060 * added support for new EAP authentication methods:
1061 EAP-TTLS/EAP-MD5-Challenge
1063 EAP-TTLS/EAP-MSCHAPv2
1071 EAP-PEAP/MD5-Challenge
1073 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1074 * added support for anonymous identity (to be used when identity is
1075 sent in plaintext; real identity will be used within TLS protected
1076 tunnel (e.g., with EAP-TTLS)
1077 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1078 * added support for requesting identity and password information using
1079 control interface; in other words, the password for EAP-PEAP or
1080 EAP-TTLS does not need to be included in the configuration file since
1081 a frontand (e.g., wpa_cli) can ask it from the user
1082 * improved RSN pre-authentication to use a candidate list and process
1083 all candidates from each scan; not only one per scan
1084 * fixed RSN IE and WPA IE capabilities field parsing
1085 * ignore Tx bit in GTK IE when Pairwise keys are used
1086 * avoid making new scan requests during IEEE 802.1X negotiation
1087 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1088 with TLS support (this replaces the included implementation with
1089 library code to save about 8 kB since the library code is needed
1091 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1092 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1095 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1097 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1098 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1099 - EAP-MD5 (cannot be used with WPA-RADIUS)
1100 [draft-ietf-eap-rfc2284bis-09.txt]
1101 - EAP-TLS [RFC 2716]
1102 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1103 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1104 [draft-kamath-pppext-eap-mschapv2-00.txt]
1105 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1106 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1107 - new configuration file options: eap, identity, password, ca_cert,
1108 client_cert, privatekey, private_key_passwd
1109 - Xsupplicant is not required anymore, but it can be used by
1110 disabling the internal IEEE 802.1X Supplicant with -e command line
1112 - this code is not included in the default build; Makefile need to
1113 be edited for this (uncomment lines for selected functionality)
1114 - EAP-TLS and EAP-PEAP require openssl libraries
1115 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1116 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1117 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1118 EAPOL-Key frames instead of WPA key handshakes)
1119 * added support for IEEE 802.11i/RSN (WPA2)
1120 - improved PTK Key Handshake
1121 - PMKSA caching, pre-authentication
1122 * fixed wpa_supplicant to ignore possible extra data after WPA
1123 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1124 TPTK' error from message 3 of 4-Way Handshake in case the AP
1125 includes extra data after the EAPOL-Key)
1126 * added interface for external programs (frontends) to control
1128 - CLI example (wpa_cli) with interactive mode and command line
1130 - replaced SIGUSR1 status/statistics with the new control interface
1131 * made some feature compile time configurable
1132 - .config file for make
1133 - driver interfaces (hostap, hermes, ..)
1134 - EAPOL/EAP functions
1137 * Initial version of wpa_supplicant
