1 ChangeLog for wpa_supplicant
3 2008-08-10 - v0.6.4
4 * added support for EAP Sequences in EAP-FAST Phase 2
5 * added support for using TNC with EAP-FAST
6 * added driver_ps3 for the PS3 Linux wireless driver
7 * added support for optional cryptobinding with PEAPv0
8 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
9 allow fallback to full handshake if server rejects PAC-Opaque
10 * added fragmentation support for EAP-TNC
11 * added support for parsing PKCS #8 formatted private keys into the
12 internal TLS implementation (both PKCS #1 RSA key and PKCS #8
13 encapsulated RSA key can now be used)
14 * added option of using faster, but larger, routines in the internal
15 LibTomMath (for internal TLS implementation) to speed up DH and RSA
16 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
17 * fixed race condition between disassociation event and group key
18 handshake to avoid getting stuck in incorrect state [Bug 261]
19 * fixed opportunistic key caching (proactive_key_caching)
21 2008-02-22 - v0.6.3
22 * removed 'nai' and 'eappsk' network configuration variables that were
23 previously used for configuring user identity and key for EAP-PSK,
24 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
25 replacement for 'nai' (if old configuration used a separate
26 'identity' value, that would now be configured as
27 'anonymous_identity'). 'password' field is now used as the
28 replacement for 'eappsk' (it can also be set using hexstring to
29 present random binary data)
30 * removed '-w' command line parameter (wait for interface to be added,
31 if needed); cleaner way of handling this functionality is to use an
32 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
33 when an interface is added
34 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
35 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
36 indicating when new scan results become available
37 * added new ctrl_iface command, BSS, to allow scan results to be
38 fetched without hitting the message size limits (this command
39 can be used to iterate through the scan results one BSS at the time)
40 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
41 attributes in EAP-SIM Start/Response when using fast reauthentication
42 * fixed EAPOL not to end up in infinite loop when processing dynamic
43 WEP keys with IEEE 802.1X
44 * fixed problems in getting NDIS events from WMI on Windows 2000
46 2008-01-01 - v0.6.2
47 * added support for Makefile builds to include debug-log-to-a-file
48 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
49 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
50 lengths properly to avoid potential crash caused by invalid messages
51 * added data structure for storing allocated buffers (struct wpabuf);
52 this does not affect wpa_supplicant usage, but many of the APIs
53 changed and various interfaces (e.g., EAP) is not compatible with old
54 versions
55 * added support for protecting EAP-AKA/Identity messages with
56 AT_CHECKCODE (optional feature in RFC 4187)
57 * added support for protected result indication with AT_RESULT_IND for
58 EAP-SIM and EAP-AKA (phase1="result_ind=1")
59 * added driver_wext workaround for race condition between scanning and
60 association with drivers that take very long time to scan all
61 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
62 using a longer hardcoded timeout for the scan if the driver supports
63 notifications for scan completion (SIOCGIWSCAN event); this helps,
64 e.g., in cases where wpa_supplicant and madwifi driver ended up in
65 loop where the driver did not even try to associate
66 * stop EAPOL timer tick when no timers are in use in order to reduce
67 power consumption (no need to wake up the process once per second)
68 [Bug 237]
69 * added support for privilege separation (run only minimal part of
70 wpa_supplicant functionality as root and rest as unprivileged,
71 non-root process); see 'Privilege separation' in README for details;
72 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
73 in .config
74 * changed scan results data structure to include all information
75 elements to make it easier to support new IEs; old get_scan_result()
76 driver_ops is still supported for backwards compatibility (results
77 are converted internally to the new format), but all drivers should
78 start using the new get_scan_results2() to make them more likely to
79 work with new features
80 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
81 application, i.e., it does not require Qt3Support anymore; Windows
82 binary of wpa_gui.exe is now from this directory and only requires
83 QtCore4.dll and QtGui4.dll libraries
84 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
85 available as a separate package to make wpa_gui installation easier:
86 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
87 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
88 only shared key/password authentication is supported in this version
90 2007-11-24 - v0.6.1
91 * added support for configuring password as NtPasswordHash
92 (16-byte MD4 hash of password) in hash:<32 hex digits> format
93 * added support for fallback from abbreviated TLS handshake to
94 full handshake when using EAP-FAST (e.g., due to an expired
95 PAC-Opaque)
96 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
97 draft (draft-ietf-emu-eap-gpsk-07.txt)
98 * added support for drivers that take care of RSN 4-way handshake
99 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
100 WPA_ALG_PMK in set_key)
101 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
102 .config); this version supports only ap_scan=2 mode and allow the
103 driver to take care of the 4-way handshake
104 * fixed a buffer overflow in parsing TSF from scan results when using
105 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
106 [Bug 232]
107 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
108 * fixed an integer overflow issue in the ASN.1 parser used by the
109 (experimental) internal TLS implementation to avoid a potential
110 buffer read overflow
111 * fixed a race condition with -W option (wait for a control interface
112 monitor before starting) that could have caused the first messages to
113 be lost
114 * added support for processing TNCC-TNCS-Messages to report
115 recommendation (allow/none/isolate) when using TNC [Bug 243]
117 2007-05-28 - v0.6.0
118 * added network configuration parameter 'frequency' for setting
119 initial channel for IBSS (adhoc) networks
120 * added experimental IEEE 802.11r/D6.0 support
121 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
122 * updated EAP-PSK to use the IANA-allocated EAP type 47
123 * fixed EAP-PAX key derivation
124 * fixed EAP-PSK bit ordering of the Flags field
125 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
126 tunnelled identity request (previously, the identifier from the outer
127 method was used, not the tunnelled identifier which could be
128 different)
129 * added support for fragmentation of outer TLS packets during Phase 2
130 of EAP-PEAP/TTLS/FAST
131 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
132 * added support for EAP-FAST authentication with inner methods that
133 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
134 for PAC provisioning)
135 * added support for authenticated EAP-FAST provisioning
136 * added support for configuring maximum number of EAP-FAST PACs to
137 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
138 * added support for storing EAP-FAST PACs in binary format
139 (fast_pac_format=binary in phase1 string)
140 * fixed dbus ctrl_iface to validate message interface before
141 dispatching to avoid a possible segfault [Bug 190]
142 * fixed PeerKey key derivation to use the correct PRF label
143 * updated Windows binary build to link against OpenSSL 0.9.8d and
144 added support for EAP-FAST
145 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
146 draft (draft-ietf-emu-eap-gpsk-04.txt)
147 * fixed EAP-AKA Notification processing to allow Notification to be
148 processed after AKA Challenge response has been sent
149 * updated to use IEEE 802.11w/D2.0 for management frame protection
150 (still experimental)
151 * fixed EAP-TTLS implementation not to crash on use of freed memory
152 if TLS library initialization fails
153 * added support for EAP-TNC (Trusted Network Connect)
154 (this version implements the EAP-TNC method and EAP-TTLS changes
155 needed to run two methods in sequence (IF-T) and the IF-IMC and
156 IF-TNCCS interfaces from TNCC)
158 2006-11-24 - v0.5.6
159 * added experimental, integrated TLSv1 client implementation with the
160 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
161 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
162 .config); this can be useful, e.g., if the target system does not
163 have a suitable TLS library and a minimal code size is required
164 (total size of this internal TLS/crypto code is bit under 50 kB on
165 x86 and the crypto code is shared by rest of the supplicant so some
166 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
167 * removed STAKey handshake since PeerKey handshake has replaced it in
168 IEEE 802.11ma and there are no known deployments of STAKey
169 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
170 draft (draft-ietf-emu-eap-gpsk-01.txt)
171 * added preliminary implementation of IEEE 802.11w/D1.0 (management
172 frame protection)
173 (Note: this requires driver support to work properly.)
174 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
175 * fixed Windows named pipes ctrl_iface to not stop listening for
176 commands if client program opens a named pipe and closes it
177 immediately without sending a command
178 * fixed USIM PIN status determination for the case that PIN is not
179 needed (this allows EAP-AKA to be used with USIM cards that do not
180 use PIN)
181 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
182 be used with cards that do not support file selection based on
183 partial AID
184 * added support for matching the subjectAltName of the authentication
185 server certificate against multiple name components (e.g.,
186 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
187 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
188 affects IEEE 802.1X with dynamic WEP keys)
189 * changed ctrl_iface network configuration 'get' operations to not
190 return password/key material; if these fields are requested, "*"
191 will be returned if the password/key is set, but the value of the
192 parameter is not exposed
194 2006-08-27 - v0.5.5
195 * added support for building Windows version with UNICODE defined
196 (wide-char functions)
197 * driver_ndis: fixed static WEP configuration to avoid race condition
198 issues with some NDIS drivers between association and setting WEP
199 keys
200 * driver_ndis: added validation for IELength value in scan results to
201 avoid crashes when using buggy NDIS drivers [Bug 165]
202 * fixed Release|Win32 target in the Visual Studio project files
203 (previously, only Debug|Win32 target was set properly)
204 * changed control interface API call wpa_ctrl_pending() to allow it to
205 return -1 on error (e.g., connection lost); control interface clients
206 will need to make sure that they verify that the value is indeed >0
207 when determining whether there are pending messages
208 * added an alternative control interface backend for Windows targets:
209 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
210 control interface mechanism for Windows builds (previously, UDP to
211 localhost was used)
212 * changed ctrl_interface configuration for UNIX domain sockets:
213 - deprecated ctrl_interface_group variable (it may be removed in
214 future versions)
215 - allow both directory and group be configured with ctrl_interface
216 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
217 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
218 case when group is not changed
219 * added support for controlling more than one interface per process in
220 Windows version
221 * added a workaround for a case where the AP is using unknown address
222 (e.g., MAC address of the wired interface) as the source address for
223 EAPOL-Key frames; previously, that source address was used as the
224 destination for EAPOL-Key frames and in key derivation; now, BSSID is
225 used even if the source address does not match with it
226 (this resolves an interoperability issue with Thomson SpeedTouch 580)
227 * added a workaround for UDP-based control interface (which was used in
228 Windows builds before this release) to prevent packets with forged
229 addresses from being accepted as local control requests
230 * removed ndis_events.cpp and possibility of using external
231 ndis_events.exe; C version (ndis_events.c) is fully functional and
232 there is no desire to maintain two separate versions of this
233 implementation
234 * ndis_events: Changed NDIS event notification design to use WMI to
235 learn the adapter description through Win32_PnPEntity class; this
236 should fix some cases where the adapter name was not recognized
237 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
238 USB) [Bug 113]
239 * fixed selection of the first network in ap_scan=2 mode; previously,
240 wpa_supplicant could get stuck in SCANNING state when only the first
241 network for enabled (e.g., after 'wpa_cli select_network 0')
242 * winsvc: added support for configuring ctrl_interface parameters in
243 registry (ctrl_interface string value in
244 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
245 required to enable control interface (previously, this was hardcoded
246 to be enabled)
247 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
248 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
250 2006-06-20 - v0.5.4
251 * fixed build with CONFIG_STAKEY=y [Bug 143]
252 * added support for doing MLME (IEEE 802.11 management frame
253 processing) in wpa_supplicant when using Devicescape IEEE 802.11
254 stack (wireless-dev.git tree)
255 * added a new network block configuration option, fragment_size, to
256 configure the maximum EAP fragment size
257 * driver_ndis: Disable WZC automatically for the selected interface to
258 avoid conflicts with two programs trying to control the radio; WZC
259 will be re-enabled (if it was enabled originally) when wpa_supplicant
260 is terminated
261 * added an experimental TLSv1 client implementation
262 (CONFIG_TLS=internal) that can be used instead of an external TLS
263 library, e.g., to reduce total size requirement on systems that do
264 not include any TLS library by default (this is not yet complete;
265 basic functionality is there, but certificate validation is not yet
266 included)
267 * added PeerKey handshake implementation for IEEE 802.11e
268 direct link setup (DLS) to replace STAKey handshake
269 * fixed WPA PSK update through ctrl_iface for the case where the old
270 PSK was derived from an ASCII passphrase and the new PSK is set as
271 a raw PSK (hex string)
272 * added new configuration option for identifying which network block
273 was used (id_str in wpa_supplicant.conf; included on
274 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
275 variable in wpa_cli action scripts; in addition WPA_ID variable is
276 set to the current unique identifier that wpa_supplicant assigned
277 automatically for the network and that can be used with
278 GET_NETWORK/SET_NETWORK ctrl_iface commands)
279 * wpa_cli action script is now called only when the connect/disconnect
280 status changes or when associating with a different network
281 * fixed configuration parser not to remove CCMP from group cipher list
282 if WPA-None (adhoc) is used (pairwise=NONE in that case)
283 * fixed integrated NDIS events processing not to hang the process due
284 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
285 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
286 draft-clancy-emu-eap-shared-secret-00.txt)
287 * added Microsoft Visual Studio 2005 solution and project files for
288 build wpa_supplicant for Windows (see vs2005 subdirectory)
289 * eloop_win: fixed unregistration of Windows events
290 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
291 at the end of RSN pre-authentication and added unregistration of
292 a Windows event to avoid getting eloop_win stuck with an invalid
293 handle
294 * driver_ndis: added support for selecting AP based on BSSID
295 * added new environmental variable for wpa_cli action scripts:
296 WPA_CTRL_DIR is the current control interface directory
297 * driver_ndis: added support for using NDISUIO instead of WinPcap for
298 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
299 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
300 wpa_supplicant without requiring WinPcap; note that using NDISUIO
301 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
302 only one application to open the device
303 * changed NDIS driver naming to only include device GUID, e.g.,
304 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
305 specific \Device\NPF_ prefix before the GUID; the prefix is still
306 allowed for backwards compatibility, but it is not required anymore
307 when specifying the interface
308 * driver_ndis: re-initialize driver interface is the adapter is removed
309 and re-inserted [Bug 159]
310 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
311 big endian hosts [Bug 146]
313 2006-04-27 - v0.5.3
314 * fixed EAP-GTC response to include correct user identity when run as
315 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
316 * driver_ndis: Fixed encryption mode configuration for unencrypted
317 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
318 refused to associate with open networks) [Bug 106]
319 * driver_ndis: use BSSID OID polling to detect when IBSS network is
320 formed even when ndis_events code is included since some NDIS drivers
321 do not generate media connect events in IBSS mode
322 * config_winreg: allow global ctrl_interface parameter to be configured
323 in Windows registry
324 * config_winreg: added support for saving configuration data into
325 Windows registry
326 * added support for controlling network device operational state
327 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
328 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
329 that can use this information)
330 * driver_wext: added support for WE-21 change to SSID configuration
331 * driver_wext: fixed privacy configuration for static WEP keys mode
332 [Bug 140]
333 * added an optional driver_ops callback for MLME-SETPROTECTION.request
334 primitive
335 * added support for EAP-SAKE (no EAP method number allocated yet, so
336 this is using the same experimental type 255 as EAP-PSK)
337 * added support for dynamically loading EAP methods (.so files) instead
338 of requiring them to be statically linked in; this is disabled by
339 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
340 on how to use this)
342 2006-03-19 - v0.5.2
343 * do not try to use USIM APDUs when initializing PC/SC for SIM card
344 access for a network that has not enabled EAP-AKA
345 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
346 v0.5.1 due to the new support for expanded EAP types)
347 * added support for generating EAP Expanded Nak
348 * try to fetch scan results once before requesting new scan when
349 starting up in ap_scan=1 mode (this can speed up initial association
350 a lot with, e.g., madwifi-ng driver)
351 * added support for receiving EAPOL frames from a Linux bridge
352 interface (-bbr0 on command line)
353 * fixed EAPOL re-authentication for sessions that used PMKSA caching
354 * changed EAP method registration to use a dynamic list of methods
355 instead of a static list generated at build time
356 * fixed PMKSA cache deinitialization not to use freed memory when
357 removing PMKSA entries
358 * fixed a memory leak in EAP-TTLS re-authentication
359 * reject WPA/WPA2 message 3/4 if it does not include any valid
360 WPA/RSN IE
361 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
362 if the driver does not support SIOCSIWAUTH
364 2006-01-29 - v0.5.1
365 * driver_test: added better support for multiple APs and STAs by using
366 a directory with sockets that include MAC address for each device in
367 the name (driver_param=test_dir=/tmp/test)
368 * added support for EAP expanded type (vendor specific EAP methods)
369 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
370 option can be changed if needed
371 * wpa_cli/wpa_gui: skip non-socket files in control directory when
372 using UNIX domain sockets; this avoids selecting an incorrect
373 interface (e.g., a PID file could be in this directory, even though
374 use of this directory for something else than socket files is not
375 recommended)
376 * fixed TLS library deinitialization after RSN pre-authentication not
377 to disable TLS library for normal authentication
378 * driver_wext: Remove null-termination from SSID length if the driver
379 used it; some Linux drivers do this and they were causing problems in
380 wpa_supplicant not finding matching configuration block. This change
381 would break a case where the SSID actually ends in '\0', but that is
382 not likely to happen in real use.
383 * fixed PMKSA cache processing not to trigger deauthentication if the
384 current PMKSA cache entry is replaced with a valid new entry
385 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
386 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
387 ap_scan=2)
389 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
390 * added experimental STAKey handshake implementation for IEEE 802.11e
391 direct link setup (DLS); note: this is disabled by default in both
392 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
393 and stakey=1)
394 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
395 decrypt AT_ENCR_DATA attributes correctly
396 * fixed EAP-AKA to allow resynchronization within the same session
397 * made code closer to ANSI C89 standard to make it easier to port to
398 other C libraries and compilers
399 * started moving operating system or C library specific functions into
400 wrapper functions defined in os.h and implemented in os_*.c to make
401 code more portable
402 * wpa_supplicant can now be built with Microsoft Visual C++
403 (e.g., with the freely available Toolkit 2003 version or Visual
404 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
405 example makefile for nmake
406 * added support for using Windows registry for command line parameters
407 (CONFIG_MAIN=main_winsvc) and configuration data
408 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
409 contents; this version can be run both as a Windows service and as a
410 normal application; 'wpasvc.exe app' to start as applicant,
411 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
412 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
413 unregister a service
414 * made it possible to link ndis_events.exe functionality into
415 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
416 * added better support for multiple control interface backends
417 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
418 * fixed PC/SC code to use correct length for GSM AUTH command buffer
419 and to not use pioRecvPci with SCardTransmit() calls; these were not
420 causing visible problems with pcsc-lite, but Windows Winscard.dll
421 refused the previously used parameters; this fixes EAP-SIM and
422 EAP-AKA authentication using SIM/USIM card under Windows
423 * added new event loop implementation for Windows using
424 WaitForMultipleObject() instead of select() in order to allow waiting
425 for non-socket objects; this can be selected with
426 CONFIG_ELOOP=eloop_win in .config
427 * added support for selecting l2_packet implementation in .config
428 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
429 winpcap, freebsd, none)
430 * added new l2_packet implementation for WinPcap
431 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
432 reduce latency in EAPOL receive processing from about 100 ms to about
433 3 ms
434 * added support for EAP-FAST key derivation using other ciphers than
435 RC4-128-SHA for authentication and AES128-SHA for provisioning
436 * added support for configuring CA certificate as DER file and as a
437 configuration blob
438 * fixed private key configuration as configuration blob and added
439 support for using PKCS#12 as a blob
440 * tls_gnutls: added support for using PKCS#12 files; added support for
441 session resumption
442 * added support for loading trusted CA certificates from Windows
443 certificate store: ca_cert="cert_store://<name>", where <name> is
444 likely CA (Intermediate CA certificates) or ROOT (root certificates)
445 * added C version of ndis_events.cpp and made it possible to build this
446 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
447 easily on cross-compilation builds
448 * added wpasvc.exe into Windows binary release; this is an alternative
449 version of wpa_supplicant.exe with configuration backend using
450 Windows registry and with the entry point designed to run as a
451 Windows service
452 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
453 wpasvc.exe and removed this additional tool from the Windows binary
454 release since it is not needed anymore
455 * load winscard.dll functions dynamically when building with MinGW
456 since MinGW does not yet include winscard library
458 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
459 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
460 and WinPcap to receive frames sent to PAE group address
461 * disable EAP state machine when IEEE 802.1X authentication is not used
462 in order to get rid of bogus "EAP failed" messages
463 * fixed OpenSSL error reporting to go through all pending errors to
464 avoid confusing reports of old errors being reported at later point
465 during handshake
466 * fixed configuration file updating to not write empty variables
467 (e.g., proto or key_mgmt) that the file parser would not accept
468 * fixed ADD_NETWORK ctrl_iface command to use the same default values
469 for variables as empty network definitions read from config file
470 would get
471 * fixed EAP state machine to not discard EAP-Failure messages in many
472 cases (e.g., during TLS handshake)
473 * fixed a infinite loop in private key reading if the configured file
474 cannot be parsed successfully
475 * driver_madwifi: added support for madwifi-ng
476 * wpa_gui: do not display password/PSK field contents
477 * wpa_gui: added CA certificate configuration
478 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
479 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
480 the new AP is using different WPA/RSN IE
481 * use longer timeout for IEEE 802.11 association to avoid problems with
482 drivers that may take more than five second to associate
484 2005-10-27 - v0.4.6
485 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
486 RSN IE, but WPA IE would match with wpa_supplicant configuration
487 * added support for named configuration blobs in order to avoid having
488 to use file system for external files (e.g., certificates);
489 variables can be set to "blob://<blob name>" instead of file path to
490 use a named blob; supported fields: pac_file, client_cert,
491 private_key
492 * fixed RSN pre-authentication (it was broken in the clean up of WPA
493 state machine interface in v0.4.5)
494 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
495 sure the driver configures broadcast decryption correctly
496 * added ca_path (and ca_path2) configuration variables that can be used
497 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
498 system-wide trusted CA list
499 * added support for starting wpa_supplicant without a configuration
500 file (-C argument must be used to set ctrl_interface parameter for
501 this case; in addition, -p argument can be used to provide
502 driver_param; these new arguments can also be used with a
503 configuration to override the values from the configuration)
504 * added global control interface that can be optionally used for adding
505 and removing network interfaces dynamically (-g command line argument
506 for both wpa_supplicant and wpa_cli) without having to restart
507 wpa_supplicant process
508 * wpa_gui:
509 - try to save configuration whenever something is modified
510 - added WEP key configuration
511 - added possibility to edit the current network configuration
512 * driver_ndis: fixed driver polling not to increase frequency on each
513 received EAPOL frame due to incorrectly cancelled timeout
514 * added simple configuration file examples (in examples subdirectory)
515 * fixed driver_wext.c to filter wireless events based on ifindex to
516 avoid interfaces receiving events from other interfaces
517 * delay sending initial EAPOL-Start couple of seconds to speed up
518 authentication for the most common case of Authenticator starting
519 EAP authentication immediately after association
521 2005-09-25 - v0.4.5
522 * added a workaround for clearing keys with ndiswrapper to allow
523 roaming from WPA enabled AP to plaintext one
524 * added docbook documentation (doc/docbook) that can be used to
525 generate, e.g., man pages
526 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
527 PF_PACKET in order to prepare for network devices that do not use
528 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
529 * use receipt of EAPOL-Key frame as a lower layer success indication
530 for EAP state machine to allow recovery from dropped EAP-Success
531 frame
532 * cleaned up internal EAPOL frame processing by not including link
533 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
534 header is added only when transmitted the frame; this makes it easier
535 to use wpa_supplicant on link layers that use different header than
536 Ethernet
537 * updated EAP-PSK to use draft 9 by default since this can now be
538 tested with hostapd; removed support for draft 3, including
539 server_nai configuration option from network blocks
540 * driver_wired: add PAE address to the multicast address list in order
541 to be able to receive EAPOL frames with drivers that do not include
542 these multicast addresses by default
543 * driver_wext: add support for WE-19
544 * added support for multiple configuration backends (CONFIG_BACKEND
545 option); currently, only 'file' is supported (i.e., the format used
546 in wpa_supplicant.conf)
547 * added support for updating configuration ('wpa_cli save_config');
548 this is disabled by default and can be enabled with global
549 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
550 and wpa_gui to store the configuration changes in a permanent store
551 * added GET_NETWORK ctrl_iface command
552 (e.g., 'wpa_cli get_network 0 ssid')
554 2005-08-21 - v0.4.4
555 * replaced OpenSSL patch for EAP-FAST support
556 (openssl-tls-extensions.patch) with a more generic and correct
557 patch (the new patch is not compatible with the previous one, so the
558 OpenSSL library will need to be patched with the new patch in order
559 to be able to build wpa_supplicant with EAP-FAST support)
560 * added support for using Windows certificate store (through CryptoAPI)
561 for client certificate and private key operations (EAP-TLS)
562 (see wpa_supplicant.conf for more information on how to configure
563 this with private_key)
564 * ported wpa_gui to Windows
565 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
566 built with the open source version of the Qt4 for Windows
567 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
568 with drivers that do not support WPA
569 * ndis_events: fixed Windows 2000 support
570 * added support for enabling/disabling networks from the list of all
571 configured networks ('wpa_cli enable_network <network id>' and
572 'wpa_cli disable_network <network id>')
573 * added support for adding and removing network from the current
574 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
575 <network id>'); added networks are disabled by default and they can
576 be enabled with enable_network command once the configuration is done
577 for the new network; note: configuration file is not yet updated, so
578 these new networks are lost when wpa_supplicant is restarted
579 * added support for setting network configuration parameters through
580 the control interface, for example:
581 wpa_cli set_network 0 ssid "\"my network\""
582 * fixed parsing of strings that include both " and # within double
583 quoted area (e.g., "start"#end")
584 * added EAP workaround for PEAP session resumption: allow outer,
585 i.e., not tunneled, EAP-Success to terminate session since; this can
586 be disabled with eap_workaround=0
587 (this was allowed for PEAPv1 before, but now it is also allowed for
588 PEAPv0 since at least one RADIUS authentication server seems to be
589 doing this for PEAPv0, too)
590 * wpa_gui: added preliminary support for adding new networks to the
591 wpa_supplicant configuration (double click on the scan results to
592 open network configuration)
594 2005-06-26 - v0.4.3
595 * removed interface for external EAPOL/EAP supplicant (e.g.,
596 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
597 anymore and is unlikely to be used by anyone
598 * driver_ndis: fixed WinPcap 3.0 support
599 * fixed build with CONFIG_DNET_PCAP=y on Linux
600 * l2_packet: moved different implementations into separate files
601 (l2_packet_*.c)
603 2005-06-12 - v0.4.2
604 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
605 (note: ipw2100-1.1.0 is likely to require an update to work with
606 this)
607 * added support for using ap_scan=2 mode with multiple network blocks;
608 wpa_supplicant will go through the networks one by one until the
609 driver reports a successful association; this uses the same order for
610 networks as scan_ssid=1 scans, i.e., the priority field is ignored
611 and the network block order in the file is used instead
612 * fixed a potential issue in RSN pre-authentication ending up using
613 freed memory if pre-authentication times out
614 * added support for matching alternative subject name extensions of the
615 authentication server certificate; new configuration variables
616 altsubject_match and altsubject_match2
617 * driver_ndis: added support for IEEE 802.1X authentication with wired
618 NDIS drivers
619 * added support for querying private key password (EAP-TLS) through the
620 control interface (wpa_cli/wpa_gui) if one is not included in the
621 configuration file
622 * driver_broadcom: fixed couple of memory leaks in scan result
623 processing
624 * EAP-PAX is now registered as EAP type 46
625 * fixed EAP-PAX MAC calculation
626 * fixed EAP-PAX CK and ICK key derivation
627 * added support for using password with EAP-PAX (as an alternative to
628 entering key with eappsk); SHA-1 hash of the password will be used as
629 the key in this case
630 * added support for arbitrary driver interface parameters through the
631 configuration file with a new driver_param field; this adds a new
632 driver_ops function set_param()
633 * added possibility to override l2_packet module with driver interface
634 API (new send_eapol handler); this can be used to implement driver
635 specific TX/RX functions for EAPOL frames
636 * fixed ctrl_interface_group processing for the case where gid is
637 entered as a number, not group name
638 * driver_test: added support for testing hostapd with wpa_supplicant
639 by using test driver interface without any kernel drivers or network
640 cards
642 2005-05-22 - v0.4.1
643 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
644 packets to be encrypted; this was apparently broken by the changed
645 ioctl order in v0.4.0
646 * driver_madwifi: added preliminary support for compiling against 'BSD'
647 branch of madwifi CVS tree
648 * added support for EAP-MSCHAPv2 password retries within the same EAP
649 authentication session
650 * added support for password changes with EAP-MSCHAPv2 (used when the
651 password has expired)
652 * added support for reading additional certificates from PKCS#12 files
653 and adding them to the certificate chain
654 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
655 were used
656 * fixed a possible double free in EAP-TTLS fast-reauthentication when
657 identity or password is entered through control interface
658 * display EAP Notification messages to user through control interface
659 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
660 * added GUI version of wpa_cli, wpa_gui; this is not build
661 automatically with 'make'; use 'make wpa_gui' to build (this requires
662 Qt development tools)
663 * added 'disconnect' command to control interface for setting
664 wpa_supplicant in state where it will not associate before
665 'reassociate' command has been used
666 * added support for selecting a network from the list of all configured
667 networks ('wpa_cli select_network <network id>'; this disabled all
668 other networks; to re-enable, 'wpa_cli select_network any')
669 * added support for getting scan results through control interface
670 * added EAP workaround for PEAPv1 session resumption: allow outer,
671 i.e., not tunneled, EAP-Success to terminate session since; this can
672 be disabled with eap_workaround=0
674 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
675 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
676 used to reduce the size of the wpa_supplicant considerably if
677 debugging code is not needed
678 * fixed EAPOL-Key validation to drop packets with invalid Key Data
679 Length; such frames could have crashed wpa_supplicant due to buffer
680 overflow
681 * added support for wired authentication (IEEE 802.1X on wired
682 Ethernet); driver interface 'wired'
683 * obsoleted set_wpa() handler in the driver interface API (it can be
684 replaced by moving enable/disable functionality into init()/deinit())
685 (calls to set_wpa() are still present for backwards compatibility,
686 but they may be removed in the future)
687 * driver_madwifi: fixed association in plaintext mode
688 * modified the EAP workaround that accepts EAP-Success with incorrect
689 Identifier to be even less strict about verification in order to
690 interoperate with some authentication servers
691 * added support for sending TLS alerts
692 * added support for 'any' SSID wildcard; if ssid is not configured or
693 is set to an empty string, any SSID will be accepted for non-WPA AP
694 * added support for asking PIN (for SIM) from frontends (e.g.,
695 wpa_cli); if a PIN is needed, but not included in the configuration
696 file, a control interface request is sent and EAP processing is
697 delayed until the PIN is available
698 * added support for using external devices (e.g., a smartcard) for
699 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
700 new wpa_supplicant.conf variables:
701 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
702 - network: engine, engine_id, key_id
703 * added experimental support for EAP-PAX
704 * added monitor mode for wpa_cli (-a<path to a program to run>) that
705 allows external commands (e.g., shell scripts) to be run based on
706 wpa_supplicant events, e.g., when authentication has been completed
707 and data connection is ready; other related wpa_cli arguments:
708 -B (run in background), -P (write PID file); wpa_supplicant has a new
709 command line argument (-W) that can be used to make it wait until a
710 control interface command is received in order to avoid missing
711 events
712 * added support for opportunistic WPA2 PMKSA key caching (disabled by
713 default, can be enabled with proactive_key_caching=1)
714 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
715 Authenticator rejects PMKSA caching attempt and the driver is not
716 using assoc_info events
717 * added -P<pid file> argument for wpa_supplicant to write the current
718 process id into a file
720 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
721 * added new phase1 option parameter, include_tls_length=1, to force
722 wpa_supplicant to add TLS Message Length field to all TLS messages
723 even if the packet is not fragmented; this may be needed with some
724 authentication servers
725 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
726 using drivers that take care of AP selection (e.g., when using
727 ap_scan=2)
728 * fixed reprocessing of pending request after ctrl_iface requests for
729 identity/password/otp
730 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
731 EAP-PEAP and EAP-TTLS
732 * all drivers using driver_wext: set interface up and select Managed
733 mode when starting wpa_supplicant; set interface down when exiting
734 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
735 ipw2100 and ipw2200; please note that this also changed the
736 configuration variable in .config to CONFIG_DRIVER_IPW
738 2005-01-24 - v0.3.6
739 * fixed a busy loop introduced in v0.3.5 for scan result processing
740 when no matching AP is found
742 2005-01-23 - v0.3.5
743 * added a workaround for an interoperability issue with a Cisco AP
744 when using WPA2-PSK
745 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
746 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
747 retransmission of dropped frames)
748 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
749 (e.g., segfault when processing EAPOL-Key frames)
750 * fixed EAP workaround and fast reauthentication configuration for
751 RSN pre-authentication; previously these were disabled and
752 pre-authentication would fail if the used authentication server
753 requires EAP workarounds
754 * added support for blacklisting APs that fail or timeout
755 authentication in ap_scan=1 mode so that all APs are tried in cases
756 where the ones with strongest signal level are failing authentication
757 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
758 authentication attempt
759 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
760 in the previous authentication (previously, only Phase 1 success was
761 verified)
763 2005-01-09 - v0.3.4
764 * added preliminary support for IBSS (ad-hoc) mode configuration
765 (mode=1 in network block); this included a new key_mgmt mode
766 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
767 key management; see wpa_supplicant.conf for more details and an
768 example on how to configure this (note: this is currently implemented
769 only for driver_hostapd.c, but the changes should be trivial to add
770 in associate() handler for other drivers, too (assuming the driver
771 supports WPA-None)
772 * added preliminary port for native Windows (i.e., no cygwin) using
773 mingw
775 2005-01-02 - v0.3.3
776 * added optional support for GNU Readline and History Libraries for
777 wpa_cli (CONFIG_READLINE)
778 * cleaned up EAP state machine <-> method interface and number of
779 small problems with error case processing not terminating on
780 EAP-Failure but waiting for timeout
781 * added couple of workarounds for interoperability issues with a
782 Cisco AP when using WPA2
783 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
784 Note: This requires a patch for openssl to add support for TLS
785 extensions and number of workarounds for operations without
786 certificates. Proof of concept type of experimental patch is
787 included in openssl-tls-extensions.patch.
789 2004-12-19 - v0.3.2
790 * fixed private key loading for cases where passphrase is not set
791 * fixed Windows/cygwin L2 packet handler freeing; previous version
792 could cause a segfault when RSN pre-authentication was completed
793 * added support for PMKSA caching with drivers that generate RSN IEs
794 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
795 but similar code can be easily added to driver_ndiswrapper.c once
796 ndiswrapper gets full support for RSN PMKSA caching
797 * improved recovery from PMKID mismatches by requesting full EAP
798 authentication in case of failed PMKSA caching attempt
799 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
800 (this requires that ndis_events is ran while wpa_supplicant is
801 running)
802 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
803 * added support for driver interfaces to replace the interface name
804 based on driver/OS specific mapping, e.g., in case of driver_ndis,
805 this allows the beginning of the adapter description to be used as
806 the interface name
807 * added support for CR+LF (Windows-style) line ends in configuration
808 file
809 * driver_ndis: enable radio before starting scanning, disable radio
810 when exiting
811 * modified association event handler to set portEnabled = FALSE before
812 clearing port Valid in order to reset EAP state machine and avoid
813 problems with new authentication getting ignored because of state
814 machines ending up in AUTHENTICATED/SUCCESS state based on old
815 information
816 * added support for driver events to add PMKID candidates in order to
817 allow drivers to give priority to most likely roaming candidates
818 * driver_hostap: moved PrivacyInvoked configuration to associate()
819 function so that this will not be set for plaintext connections
820 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
821 interface can distinguish plaintext and IEEE 802.1X (no WPA)
822 authentication
823 * fixed static WEP key configuration to use broadcast/default type for
824 all keys (previously, the default TX key was configured as pairwise/
825 unicast key)
826 * driver_ndis: added legacy WPA capability detection for non-WPA2
827 drivers
828 * added support for setting static WEP keys for IEEE 802.1X without
829 dynamic WEP keying (eapol_flags=0)
831 2004-12-12 - v0.3.1
832 * added support for reading PKCS#12 (PFX) files (as a replacement for
833 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
834 * fixed compilation with CONFIG_PCSC=y
835 * added new ap_scan mode, ap_scan=2, for drivers that take care of
836 association, but need to be configured with security policy and SSID,
837 e.g., ndiswrapper and NDIS driver; this mode should allow such
838 drivers to work with hidden SSIDs and optimized roaming; when
839 ap_scan=2 is used, only the first network block in the configuration
840 file is used and this configuration should have explicit security
841 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
842 group, proto variables
843 * added experimental port of wpa_supplicant for Windows
844 - driver_ndis.c driver interface (NDIS OIDs)
845 - currently, this requires cygwin and WinPcap
846 - small utility, win_if_list, can be used to get interface name
847 * control interface can now be removed at build time; add
848 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
849 * optional Xsupplicant interface can now be removed at build time;
850 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
851 * added auth_alg to driver interface associate() parameters to make it
852 easier for drivers to configure authentication algorithm as part of
853 the association
855 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
856 * driver_broadcom: added new driver interface for Broadcom wl.o driver
857 (a generic driver for Broadcom IEEE 802.11a/g cards)
858 * wpa_cli: fixed parsing of -p <path> command line argument
859 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
860 ACK, not tunneled EAP-Success (of which only the first byte was
861 actually send due to a bug in previous code); this seems to
862 interoperate with most RADIUS servers that implements PEAPv1
863 * PEAPv1: added support for terminating PEAP authentication on tunneled
864 EAP-Success message; this can be configured by adding
865 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
866 (some RADIUS servers require this whereas others require a tunneled
867 reply
868 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
869 the old label for key derivation; previously, the default was 1,
870 but it looks like most existing PEAPv1 implementations use the old
871 label which is thus more suitable default option
872 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
873 * fixed parsing of wep_tx_keyidx
874 * added support for configuring list of allowed Phase 2 EAP types
875 (for both EAP-PEAP and EAP-TTLS) instead of only one type
876 * added support for configuring IEEE 802.11 authentication algorithm
877 (auth_alg; mainly for using Shared Key authentication with static
878 WEP keys)
879 * added support for EAP-AKA (with UMTS SIM)
880 * fixed couple of errors in PCSC handling that could have caused
881 random-looking errors for EAP-SIM
882 * added support for EAP-SIM pseudonyms and fast re-authentication
883 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
884 session resumption)
885 * added support for EAP-SIM with two challanges
886 (phase1="sim_min_num_chal=3" can be used to require three challenges)
887 * added support for configuring DH/DSA parameters for an ephemeral DH
888 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
889 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
890 and optional DH key exchange to achieve forward secracy with RSA keys
891 * added support for matching subject of the authentication server
892 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
893 configuration variables subject_match and subject_match2
894 * changed SSID configuration in driver_wext.c (used by many driver
895 interfaces) to use ssid_len+1 as the length for SSID since some Linux
896 drivers expect this
897 * fixed couple of unaligned reads in scan result parsing to fix WPA
898 connection on some platforms (e.g., ARM)
899 * added driver interface for Intel ipw2100 driver
900 * added support for LEAP with WPA
901 * added support for larger scan results report (old limit was 4 kB of
902 data, i.e., about 35 or so APs) when using Linux wireless extensions
903 v17 or newer
904 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
905 only if there is a PMKSA cache entry for the current AP
906 * fixed error handling for case where reading of scan results fails:
907 must schedule a new scan or wpa_supplicant will remain waiting
908 forever
909 * changed debug output to remove shared password/key material by
910 default; all key information can be included with -K command line
911 argument to match the previous behavior
912 * added support for timestamping debug log messages (disabled by
913 default, can be enabled with -t command line argument)
914 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
915 if keys are not configured to be used; this fixes IEEE 802.1X mode
916 with drivers that use this information to configure whether Privacy
917 bit can be in Beacon frames (e.g., ndiswrapper)
918 * avoid clearing driver keys if no keys have been configured since last
919 key clear request; this seems to improve reliability of group key
920 handshake for ndiswrapper & NDIS driver which seems to be suffering
921 of some kind of timing issue when the keys are cleared again after
922 association
923 * changed driver interface API:
924 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
925 version is being used (now, this is set to 2; previously, it was
926 not defined)
927 - pass pointer to private data structure to all calls
928 - the new API is not backwards compatible; all in-tree driver
929 interfaces has been converted to the new API
930 * added support for controlling multiple interfaces (radios) per
931 wpa_supplicant process; each interface needs to be listed on the
932 command line (-c, -i, -D arguments) with -N as a separator
933 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
934 * added a workaround for EAP servers that incorrectly use same Id for
935 sequential EAP packets
936 * changed libpcap/libdnet configuration to use .config variable,
937 CONFIG_DNET_PCAP, instead of requiring Makefile modification
938 * improved downgrade attack detection in IE verification of msg 3/4:
939 verify both WPA and RSN IEs, if present, not only the selected one;
940 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
941 Probe Response frame, and RSN is enabled in wpa_supplicant
942 configuration
943 * fixed WPA msg 3/4 processing to allow Key Data field contain other
944 IEs than just one WPA IE
945 * added support for FreeBSD and driver interface for the BSD net80211
946 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
947 required kernel mods have not yet been committed
948 * made EAP workarounds configurable; enabled by default, can be
949 disabled with network block option eap_workaround=0
951 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
952 * resolved couple of interoperability issues with EAP-PEAPv1 and
953 Phase 2 (inner EAP) fragment reassembly
954 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
955 AP is using non-zero key index for the unicast key and key index zero
956 for the broadcast key
957 * driver_hostap: fixed IEEE 802.1X WEP key updates and
958 re-authentication by allowing unencrypted EAPOL frames when not using
959 WPA
960 * added a new driver interface, 'wext', which uses only standard,
961 driver independent functionality in Linux wireless extensions;
962 currently, this can be used only for non-WPA IEEE 802.1X mode, but
963 eventually, this is to be extended to support full WPA/WPA2 once
964 Linux wireless extensions get support for this
965 * added support for mode in which the driver is responsible for AP
966 scanning and selection; this is disabled by default and can be
967 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
968 this mode can be used, e.g., with generic 'wext' driver interface to
969 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
970 supporting wireless extensions.
971 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
972 operation with an AP that does not include SSID in the Beacon frames)
973 * added support for new EAP authentication methods:
974 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
975 * added support for asking one-time-passwords from frontends (e.g.,
976 wpa_cli); this 'otp' command works otherwise like 'password' command,
977 but the password is used only once and the frontend will be asked for
978 a new password whenever a request from authenticator requires a
979 password; this can be used with both EAP-OTP and EAP-GTC
980 * changed wpa_cli to automatically re-establish connection so that it
981 does not need to be re-started when wpa_supplicant is terminated and
982 started again
983 * improved user data (identity/password/otp) requests through
984 frontends: process pending EAPOL packets after getting new
985 information so that full authentication does not need to be
986 restarted; in addition, send pending requests again whenever a new
987 frontend is attached
988 * changed control frontends to use a new directory for socket files to
989 make it easier for wpa_cli to automatically select between interfaces
990 and to provide access control for the control interface;
991 wpa_supplicant.conf: ctrl_interface is now a path
992 (/var/run/wpa_supplicant is the recommended path) and
993 ctrl_interface_group can be used to select which group gets access to
994 the control interface;
995 wpa_cli: by default, try to connect to the first interface available
996 in /var/run/wpa_supplicant; this path can be overriden with -p option
997 and an interface can be selected with -i option (i.e., in most common
998 cases, wpa_cli does not need to get any arguments)
999 * added support for LEAP
1000 * added driver interface for Linux ndiswrapper
1001 * added priority option for network blocks in the configuration file;
1002 this allows networks to be grouped based on priority (the scan
1003 results are searched for matches with network blocks in this order)
1005 2004-06-20 - v0.2.3
1006 * sort scan results to improve AP selection
1007 * fixed control interface socket removal for some error cases
1008 * improved scan requesting and authentication timeout
1009 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1010 TLS processing
1011 * PEAP version can now be forced with phase1="peapver=<ver>"
1012 (mostly for testing; by default, the highest version supported by
1013 both the Supplicant and Authentication Server is selected
1014 automatically)
1015 * added support for madwifi driver (Atheros ar521x)
1016 * added a workaround for cases where AP sets Install Tx/Rx bit for
1017 WPA Group Key messages when pairwise keys are used (without this,
1018 the Group Key would be used for Tx and the AP would drop frames
1019 from the station)
1020 * added GSM SIM/USIM interface for GSM authentication algorithm for
1021 EAP-SIM; this requires pcsc-lite
1022 * added support for ATMEL AT76C5XXx driver
1023 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1024 does not include key data in the EAPOL-Key frame (i.e., part of
1025 EAP keying material is used as data encryption key)
1026 * added support for using plaintext and static WEP networks
1027 (key_mgmt=NONE)
1029 2004-05-31 - v0.2.2
1030 * added support for new EAP authentication methods:
1031 EAP-TTLS/EAP-MD5-Challenge
1032 EAP-TTLS/EAP-GTC
1033 EAP-TTLS/EAP-MSCHAPv2
1034 EAP-TTLS/EAP-TLS
1035 EAP-TTLS/MSCHAPv2
1036 EAP-TTLS/MSCHAP
1037 EAP-TTLS/PAP
1038 EAP-TTLS/CHAP
1039 EAP-PEAP/TLS
1040 EAP-PEAP/GTC
1041 EAP-PEAP/MD5-Challenge
1042 EAP-GTC
1043 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1044 * added support for anonymous identity (to be used when identity is
1045 sent in plaintext; real identity will be used within TLS protected
1046 tunnel (e.g., with EAP-TTLS)
1047 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1048 * added support for requesting identity and password information using
1049 control interface; in other words, the password for EAP-PEAP or
1050 EAP-TTLS does not need to be included in the configuration file since
1051 a frontand (e.g., wpa_cli) can ask it from the user
1052 * improved RSN pre-authentication to use a candidate list and process
1053 all candidates from each scan; not only one per scan
1054 * fixed RSN IE and WPA IE capabilities field parsing
1055 * ignore Tx bit in GTK IE when Pairwise keys are used
1056 * avoid making new scan requests during IEEE 802.1X negotiation
1057 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1058 with TLS support (this replaces the included implementation with
1059 library code to save about 8 kB since the library code is needed
1060 anyway for TLS)
1061 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1062 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1064 2004-05-06 - v0.2.1
1065 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1066 Supplicant
1067 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1068 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1069 - EAP-MD5 (cannot be used with WPA-RADIUS)
1070 [draft-ietf-eap-rfc2284bis-09.txt]
1071 - EAP-TLS [RFC 2716]
1072 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1073 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1074 [draft-kamath-pppext-eap-mschapv2-00.txt]
1075 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1076 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1077 - new configuration file options: eap, identity, password, ca_cert,
1078 client_cert, privatekey, private_key_passwd
1079 - Xsupplicant is not required anymore, but it can be used by
1080 disabling the internal IEEE 802.1X Supplicant with -e command line
1081 option
1082 - this code is not included in the default build; Makefile need to
1083 be edited for this (uncomment lines for selected functionality)
1084 - EAP-TLS and EAP-PEAP require openssl libraries
1085 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1086 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1087 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1088 EAPOL-Key frames instead of WPA key handshakes)
1089 * added support for IEEE 802.11i/RSN (WPA2)
1090 - improved PTK Key Handshake
1091 - PMKSA caching, pre-authentication
1092 * fixed wpa_supplicant to ignore possible extra data after WPA
1093 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1094 TPTK' error from message 3 of 4-Way Handshake in case the AP
1095 includes extra data after the EAPOL-Key)
1096 * added interface for external programs (frontends) to control
1097 wpa_supplicant
1098 - CLI example (wpa_cli) with interactive mode and command line
1099 mode
1100 - replaced SIGUSR1 status/statistics with the new control interface
1101 * made some feature compile time configurable
1102 - .config file for make
1103 - driver interfaces (hostap, hermes, ..)
1104 - EAPOL/EAP functions
1106 2004-02-15 - v0.2.0
1107 * Initial version of wpa_supplicant
