[thirdparty/hostap.git] / wpa_supplicant / ChangeLog
1 ChangeLog for wpa_supplicant
2
3 2008-11-01 - v0.6.5
4 * added support for SHA-256 as X.509 certificate digest when using the
5 internal X.509/TLSv1 implementation
6 * updated management frame protection to use IEEE 802.11w/D6.0
7 * added support for using SHA256-based stronger key derivation for WPA2
8 (IEEE 802.11w)
9 * fixed FT (IEEE 802.11r) authentication after a failed association to
10 use correct FTIE
11 * added support for configuring Phase 2 (inner/tunneled) authentication
12 method with wpa_gui-qt4
13
14 2008-08-10 - v0.6.4
15 * added support for EAP Sequences in EAP-FAST Phase 2
16 * added support for using TNC with EAP-FAST
17 * added driver_ps3 for the PS3 Linux wireless driver
18 * added support for optional cryptobinding with PEAPv0
19 * fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
20 allow fallback to full handshake if server rejects PAC-Opaque
21 * added fragmentation support for EAP-TNC
22 * added support for parsing PKCS #8 formatted private keys into the
23 internal TLS implementation (both PKCS #1 RSA key and PKCS #8
24 encapsulated RSA key can now be used)
25 * added option of using faster, but larger, routines in the internal
26 LibTomMath (for internal TLS implementation) to speed up DH and RSA
27 calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
28 * fixed race condition between disassociation event and group key
29 handshake to avoid getting stuck in incorrect state [Bug 261]
30 * fixed opportunistic key caching (proactive_key_caching)
31
32 2008-02-22 - v0.6.3
33 * removed 'nai' and 'eappsk' network configuration variables that were
34 previously used for configuring user identity and key for EAP-PSK,
35 EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
36 replacement for 'nai' (if old configuration used a separate
37 'identity' value, that would now be configured as
38 'anonymous_identity'). 'password' field is now used as the
39 replacement for 'eappsk' (it can also be set using hexstring to
40 present random binary data)
41 * removed '-w' command line parameter (wait for interface to be added,
42 if needed); cleaner way of handling this functionality is to use an
43 external mechanism (e.g., hotplug scripts) that start wpa_supplicant
44 when an interface is added
45 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
46 * added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
47 indicating when new scan results become available
48 * added new ctrl_iface command, BSS, to allow scan results to be
49 fetched without hitting the message size limits (this command
50 can be used to iterate through the scan results one BSS at the time)
51 * fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
52 attributes in EAP-SIM Start/Response when using fast reauthentication
53 * fixed EAPOL not to end up in infinite loop when processing dynamic
54 WEP keys with IEEE 802.1X
55 * fixed problems in getting NDIS events from WMI on Windows 2000
56
57 2008-01-01 - v0.6.2
58 * added support for Makefile builds to include debug-log-to-a-file
59 functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
60 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
61 lengths properly to avoid potential crash caused by invalid messages
62 * added data structure for storing allocated buffers (struct wpabuf);
63 this does not affect wpa_supplicant usage, but many of the APIs
64 changed and various interfaces (e.g., EAP) is not compatible with old
65 versions
66 * added support for protecting EAP-AKA/Identity messages with
67 AT_CHECKCODE (optional feature in RFC 4187)
68 * added support for protected result indication with AT_RESULT_IND for
69 EAP-SIM and EAP-AKA (phase1="result_ind=1")
70 * added driver_wext workaround for race condition between scanning and
71 association with drivers that take very long time to scan all
72 channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
73 using a longer hardcoded timeout for the scan if the driver supports
74 notifications for scan completion (SIOCGIWSCAN event); this helps,
75 e.g., in cases where wpa_supplicant and madwifi driver ended up in
76 loop where the driver did not even try to associate
77 * stop EAPOL timer tick when no timers are in use in order to reduce
78 power consumption (no need to wake up the process once per second)
79 [Bug 237]
80 * added support for privilege separation (run only minimal part of
81 wpa_supplicant functionality as root and rest as unprivileged,
82 non-root process); see 'Privilege separation' in README for details;
83 this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
84 in .config
85 * changed scan results data structure to include all information
86 elements to make it easier to support new IEs; old get_scan_result()
87 driver_ops is still supported for backwards compatibility (results
88 are converted internally to the new format), but all drivers should
89 start using the new get_scan_results2() to make them more likely to
90 work with new features
91 * Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
92 application, i.e., it does not require Qt3Support anymore; Windows
93 binary of wpa_gui.exe is now from this directory and only requires
94 QtCore4.dll and QtGui4.dll libraries
95 * updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
96 available as a separate package to make wpa_gui installation easier:
97 http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
98 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
99 only shared key/password authentication is supported in this version
100
101 2007-11-24 - v0.6.1
102 * added support for configuring password as NtPasswordHash
103 (16-byte MD4 hash of password) in hash:<32 hex digits> format
104 * added support for fallback from abbreviated TLS handshake to
105 full handshake when using EAP-FAST (e.g., due to an expired
106 PAC-Opaque)
107 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
108 draft (draft-ietf-emu-eap-gpsk-07.txt)
109 * added support for drivers that take care of RSN 4-way handshake
110 internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
111 WPA_ALG_PMK in set_key)
112 * added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
113 .config); this version supports only ap_scan=2 mode and allow the
114 driver to take care of the 4-way handshake
115 * fixed a buffer overflow in parsing TSF from scan results when using
116 driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
117 [Bug 232]
118 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
119 * fixed an integer overflow issue in the ASN.1 parser used by the
120 (experimental) internal TLS implementation to avoid a potential
121 buffer read overflow
122 * fixed a race condition with -W option (wait for a control interface
123 monitor before starting) that could have caused the first messages to
124 be lost
125 * added support for processing TNCC-TNCS-Messages to report
126 recommendation (allow/none/isolate) when using TNC [Bug 243]
127
128 2007-05-28 - v0.6.0
129 * added network configuration parameter 'frequency' for setting
130 initial channel for IBSS (adhoc) networks
131 * added experimental IEEE 802.11r/D6.0 support
132 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
133 * updated EAP-PSK to use the IANA-allocated EAP type 47
134 * fixed EAP-PAX key derivation
135 * fixed EAP-PSK bit ordering of the Flags field
136 * fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
137 tunnelled identity request (previously, the identifier from the outer
138 method was used, not the tunnelled identifier which could be
139 different)
140 * added support for fragmentation of outer TLS packets during Phase 2
141 of EAP-PEAP/TTLS/FAST
142 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
143 * added support for EAP-FAST authentication with inner methods that
144 generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
145 for PAC provisioning)
146 * added support for authenticated EAP-FAST provisioning
147 * added support for configuring maximum number of EAP-FAST PACs to
148 store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
149 * added support for storing EAP-FAST PACs in binary format
150 (fast_pac_format=binary in phase1 string)
151 * fixed dbus ctrl_iface to validate message interface before
152 dispatching to avoid a possible segfault [Bug 190]
153 * fixed PeerKey key derivation to use the correct PRF label
154 * updated Windows binary build to link against OpenSSL 0.9.8d and
155 added support for EAP-FAST
156 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
157 draft (draft-ietf-emu-eap-gpsk-04.txt)
158 * fixed EAP-AKA Notification processing to allow Notification to be
159 processed after AKA Challenge response has been sent
160 * updated to use IEEE 802.11w/D2.0 for management frame protection
161 (still experimental)
162 * fixed EAP-TTLS implementation not to crash on use of freed memory
163 if TLS library initialization fails
164 * added support for EAP-TNC (Trusted Network Connect)
165 (this version implements the EAP-TNC method and EAP-TTLS changes
166 needed to run two methods in sequence (IF-T) and the IF-IMC and
167 IF-TNCCS interfaces from TNCC)
168
169 2006-11-24 - v0.5.6
170 * added experimental, integrated TLSv1 client implementation with the
171 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
172 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
173 .config); this can be useful, e.g., if the target system does not
174 have a suitable TLS library and a minimal code size is required
175 (total size of this internal TLS/crypto code is bit under 50 kB on
176 x86 and the crypto code is shared by rest of the supplicant so some
177 of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
178 * removed STAKey handshake since PeerKey handshake has replaced it in
179 IEEE 802.11ma and there are no known deployments of STAKey
180 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
181 draft (draft-ietf-emu-eap-gpsk-01.txt)
182 * added preliminary implementation of IEEE 802.11w/D1.0 (management
183 frame protection)
184 (Note: this requires driver support to work properly.)
185 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
186 * fixed Windows named pipes ctrl_iface to not stop listening for
187 commands if client program opens a named pipe and closes it
188 immediately without sending a command
189 * fixed USIM PIN status determination for the case that PIN is not
190 needed (this allows EAP-AKA to be used with USIM cards that do not
191 use PIN)
192 * added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
193 be used with cards that do not support file selection based on
194 partial AID
195 * added support for matching the subjectAltName of the authentication
196 server certificate against multiple name components (e.g.,
197 altsubject_match="DNS:server.example.com;DNS:server2.example.com")
198 * fixed EAP-SIM/AKA key derivation for re-authentication case (only
199 affects IEEE 802.1X with dynamic WEP keys)
200 * changed ctrl_iface network configuration 'get' operations to not
201 return password/key material; if these fields are requested, "*"
202 will be returned if the password/key is set, but the value of the
203 parameter is not exposed
204
205 2006-08-27 - v0.5.5
206 * added support for building Windows version with UNICODE defined
207 (wide-char functions)
208 * driver_ndis: fixed static WEP configuration to avoid race condition
209 issues with some NDIS drivers between association and setting WEP
210 keys
211 * driver_ndis: added validation for IELength value in scan results to
212 avoid crashes when using buggy NDIS drivers [Bug 165]
213 * fixed Release|Win32 target in the Visual Studio project files
214 (previously, only Debug|Win32 target was set properly)
215 * changed control interface API call wpa_ctrl_pending() to allow it to
216 return -1 on error (e.g., connection lost); control interface clients
217 will need to make sure that they verify that the value is indeed >0
218 when determining whether there are pending messages
219 * added an alternative control interface backend for Windows targets:
220 Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
221 control interface mechanism for Windows builds (previously, UDP to
222 localhost was used)
223 * changed ctrl_interface configuration for UNIX domain sockets:
224 - deprecated ctrl_interface_group variable (it may be removed in
225 future versions)
226 - allow both directory and group be configured with ctrl_interface
227 in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
228 - ctrl_interface=/var/run/wpa_supplicant is still supported for the
229 case when group is not changed
230 * added support for controlling more than one interface per process in
231 Windows version
232 * added a workaround for a case where the AP is using unknown address
233 (e.g., MAC address of the wired interface) as the source address for
234 EAPOL-Key frames; previously, that source address was used as the
235 destination for EAPOL-Key frames and in key derivation; now, BSSID is
236 used even if the source address does not match with it
237 (this resolves an interoperability issue with Thomson SpeedTouch 580)
238 * added a workaround for UDP-based control interface (which was used in
239 Windows builds before this release) to prevent packets with forged
240 addresses from being accepted as local control requests
241 * removed ndis_events.cpp and possibility of using external
242 ndis_events.exe; C version (ndis_events.c) is fully functional and
243 there is no desire to maintain two separate versions of this
244 implementation
245 * ndis_events: Changed NDIS event notification design to use WMI to
246 learn the adapter description through Win32_PnPEntity class; this
247 should fix some cases where the adapter name was not recognized
248 correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
249 USB) [Bug 113]
250 * fixed selection of the first network in ap_scan=2 mode; previously,
251 wpa_supplicant could get stuck in SCANNING state when only the first
252 network for enabled (e.g., after 'wpa_cli select_network 0')
253 * winsvc: added support for configuring ctrl_interface parameters in
254 registry (ctrl_interface string value in
255 HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
256 required to enable control interface (previously, this was hardcoded
257 to be enabled)
258 * allow wpa_gui subdirectory to be built with both Qt3 and Qt4
259 * converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
260
261 2006-06-20 - v0.5.4
262 * fixed build with CONFIG_STAKEY=y [Bug 143]
263 * added support for doing MLME (IEEE 802.11 management frame
264 processing) in wpa_supplicant when using Devicescape IEEE 802.11
265 stack (wireless-dev.git tree)
266 * added a new network block configuration option, fragment_size, to
267 configure the maximum EAP fragment size
268 * driver_ndis: Disable WZC automatically for the selected interface to
269 avoid conflicts with two programs trying to control the radio; WZC
270 will be re-enabled (if it was enabled originally) when wpa_supplicant
271 is terminated
272 * added an experimental TLSv1 client implementation
273 (CONFIG_TLS=internal) that can be used instead of an external TLS
274 library, e.g., to reduce total size requirement on systems that do
275 not include any TLS library by default (this is not yet complete;
276 basic functionality is there, but certificate validation is not yet
277 included)
278 * added PeerKey handshake implementation for IEEE 802.11e
279 direct link setup (DLS) to replace STAKey handshake
280 * fixed WPA PSK update through ctrl_iface for the case where the old
281 PSK was derived from an ASCII passphrase and the new PSK is set as
282 a raw PSK (hex string)
283 * added new configuration option for identifying which network block
284 was used (id_str in wpa_supplicant.conf; included on
285 WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
286 variable in wpa_cli action scripts; in addition WPA_ID variable is
287 set to the current unique identifier that wpa_supplicant assigned
288 automatically for the network and that can be used with
289 GET_NETWORK/SET_NETWORK ctrl_iface commands)
290 * wpa_cli action script is now called only when the connect/disconnect
291 status changes or when associating with a different network
292 * fixed configuration parser not to remove CCMP from group cipher list
293 if WPA-None (adhoc) is used (pairwise=NONE in that case)
294 * fixed integrated NDIS events processing not to hang the process due
295 to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
296 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
297 draft-clancy-emu-eap-shared-secret-00.txt)
298 * added Microsoft Visual Studio 2005 solution and project files for
299 build wpa_supplicant for Windows (see vs2005 subdirectory)
300 * eloop_win: fixed unregistration of Windows events
301 * l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
302 at the end of RSN pre-authentication and added unregistration of
303 a Windows event to avoid getting eloop_win stuck with an invalid
304 handle
305 * driver_ndis: added support for selecting AP based on BSSID
306 * added new environmental variable for wpa_cli action scripts:
307 WPA_CTRL_DIR is the current control interface directory
308 * driver_ndis: added support for using NDISUIO instead of WinPcap for
309 OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
310 l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
311 wpa_supplicant without requiring WinPcap; note that using NDISUIO
312 requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
313 only one application to open the device
314 * changed NDIS driver naming to only include device GUID, e.g.,
315 {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
316 specific \Device\NPF_ prefix before the GUID; the prefix is still
317 allowed for backwards compatibility, but it is not required anymore
318 when specifying the interface
319 * driver_ndis: re-initialize driver interface is the adapter is removed
320 and re-inserted [Bug 159]
321 * driver_madwifi: fixed TKIP and CCMP sequence number configuration on
322 big endian hosts [Bug 146]
323
324 2006-04-27 - v0.5.3
325 * fixed EAP-GTC response to include correct user identity when run as
326 phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
327 * driver_ndis: Fixed encryption mode configuration for unencrypted
328 networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
329 refused to associate with open networks) [Bug 106]
330 * driver_ndis: use BSSID OID polling to detect when IBSS network is
331 formed even when ndis_events code is included since some NDIS drivers
332 do not generate media connect events in IBSS mode
333 * config_winreg: allow global ctrl_interface parameter to be configured
334 in Windows registry
335 * config_winreg: added support for saving configuration data into
336 Windows registry
337 * added support for controlling network device operational state
338 (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
339 http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
340 that can use this information)
341 * driver_wext: added support for WE-21 change to SSID configuration
342 * driver_wext: fixed privacy configuration for static WEP keys mode
343 [Bug 140]
344 * added an optional driver_ops callback for MLME-SETPROTECTION.request
345 primitive
346 * added support for EAP-SAKE (no EAP method number allocated yet, so
347 this is using the same experimental type 255 as EAP-PSK)
348 * added support for dynamically loading EAP methods (.so files) instead
349 of requiring them to be statically linked in; this is disabled by
350 default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
351 on how to use this)
352
353 2006-03-19 - v0.5.2
354 * do not try to use USIM APDUs when initializing PC/SC for SIM card
355 access for a network that has not enabled EAP-AKA
356 * fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
357 v0.5.1 due to the new support for expanded EAP types)
358 * added support for generating EAP Expanded Nak
359 * try to fetch scan results once before requesting new scan when
360 starting up in ap_scan=1 mode (this can speed up initial association
361 a lot with, e.g., madwifi-ng driver)
362 * added support for receiving EAPOL frames from a Linux bridge
363 interface (-bbr0 on command line)
364 * fixed EAPOL re-authentication for sessions that used PMKSA caching
365 * changed EAP method registration to use a dynamic list of methods
366 instead of a static list generated at build time
367 * fixed PMKSA cache deinitialization not to use freed memory when
368 removing PMKSA entries
369 * fixed a memory leak in EAP-TTLS re-authentication
370 * reject WPA/WPA2 message 3/4 if it does not include any valid
371 WPA/RSN IE
372 * driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
373 if the driver does not support SIOCSIWAUTH
374
375 2006-01-29 - v0.5.1
376 * driver_test: added better support for multiple APs and STAs by using
377 a directory with sockets that include MAC address for each device in
378 the name (driver_param=test_dir=/tmp/test)
379 * added support for EAP expanded type (vendor specific EAP methods)
380 * added AP_SCAN command into ctrl_iface so that ap_scan configuration
381 option can be changed if needed
382 * wpa_cli/wpa_gui: skip non-socket files in control directory when
383 using UNIX domain sockets; this avoids selecting an incorrect
384 interface (e.g., a PID file could be in this directory, even though
385 use of this directory for something else than socket files is not
386 recommended)
387 * fixed TLS library deinitialization after RSN pre-authentication not
388 to disable TLS library for normal authentication
389 * driver_wext: Remove null-termination from SSID length if the driver
390 used it; some Linux drivers do this and they were causing problems in
391 wpa_supplicant not finding matching configuration block. This change
392 would break a case where the SSID actually ends in '\0', but that is
393 not likely to happen in real use.
394 * fixed PMKSA cache processing not to trigger deauthentication if the
395 current PMKSA cache entry is replaced with a valid new entry
396 * fixed PC/SC initialization for ap_scan != 1 modes (this fixes
397 EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
398 ap_scan=2)
399
400 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
401 * added experimental STAKey handshake implementation for IEEE 802.11e
402 direct link setup (DLS); note: this is disabled by default in both
403 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
404 and stakey=1)
405 * fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
406 decrypt AT_ENCR_DATA attributes correctly
407 * fixed EAP-AKA to allow resynchronization within the same session
408 * made code closer to ANSI C89 standard to make it easier to port to
409 other C libraries and compilers
410 * started moving operating system or C library specific functions into
411 wrapper functions defined in os.h and implemented in os_*.c to make
412 code more portable
413 * wpa_supplicant can now be built with Microsoft Visual C++
414 (e.g., with the freely available Toolkit 2003 version or Visual
415 C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
416 example makefile for nmake
417 * added support for using Windows registry for command line parameters
418 (CONFIG_MAIN=main_winsvc) and configuration data
419 (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
420 contents; this version can be run both as a Windows service and as a
421 normal application; 'wpasvc.exe app' to start as applicant,
422 'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
423 'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
424 unregister a service
425 * made it possible to link ndis_events.exe functionality into
426 wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
427 * added better support for multiple control interface backends
428 (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
429 * fixed PC/SC code to use correct length for GSM AUTH command buffer
430 and to not use pioRecvPci with SCardTransmit() calls; these were not
431 causing visible problems with pcsc-lite, but Windows Winscard.dll
432 refused the previously used parameters; this fixes EAP-SIM and
433 EAP-AKA authentication using SIM/USIM card under Windows
434 * added new event loop implementation for Windows using
435 WaitForMultipleObject() instead of select() in order to allow waiting
436 for non-socket objects; this can be selected with
437 CONFIG_ELOOP=eloop_win in .config
438 * added support for selecting l2_packet implementation in .config
439 (CONFIG_L2_PACKET; following options are available now: linux, pcap,
440 winpcap, freebsd, none)
441 * added new l2_packet implementation for WinPcap
442 (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
443 reduce latency in EAPOL receive processing from about 100 ms to about
444 3 ms
445 * added support for EAP-FAST key derivation using other ciphers than
446 RC4-128-SHA for authentication and AES128-SHA for provisioning
447 * added support for configuring CA certificate as DER file and as a
448 configuration blob
449 * fixed private key configuration as configuration blob and added
450 support for using PKCS#12 as a blob
451 * tls_gnutls: added support for using PKCS#12 files; added support for
452 session resumption
453 * added support for loading trusted CA certificates from Windows
454 certificate store: ca_cert="cert_store://<name>", where <name> is
455 likely CA (Intermediate CA certificates) or ROOT (root certificates)
456 * added C version of ndis_events.cpp and made it possible to build this
457 with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
458 easily on cross-compilation builds
459 * added wpasvc.exe into Windows binary release; this is an alternative
460 version of wpa_supplicant.exe with configuration backend using
461 Windows registry and with the entry point designed to run as a
462 Windows service
463 * integrated ndis_events.exe functionality into wpa_supplicant.exe and
464 wpasvc.exe and removed this additional tool from the Windows binary
465 release since it is not needed anymore
466 * load winscard.dll functions dynamically when building with MinGW
467 since MinGW does not yet include winscard library
468
469 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
470 * l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
471 and WinPcap to receive frames sent to PAE group address
472 * disable EAP state machine when IEEE 802.1X authentication is not used
473 in order to get rid of bogus "EAP failed" messages
474 * fixed OpenSSL error reporting to go through all pending errors to
475 avoid confusing reports of old errors being reported at later point
476 during handshake
477 * fixed configuration file updating to not write empty variables
478 (e.g., proto or key_mgmt) that the file parser would not accept
479 * fixed ADD_NETWORK ctrl_iface command to use the same default values
480 for variables as empty network definitions read from config file
481 would get
482 * fixed EAP state machine to not discard EAP-Failure messages in many
483 cases (e.g., during TLS handshake)
484 * fixed a infinite loop in private key reading if the configured file
485 cannot be parsed successfully
486 * driver_madwifi: added support for madwifi-ng
487 * wpa_gui: do not display password/PSK field contents
488 * wpa_gui: added CA certificate configuration
489 * driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
490 * driver_ndis: include Beacon IEs in AssocInfo in order to notice if
491 the new AP is using different WPA/RSN IE
492 * use longer timeout for IEEE 802.11 association to avoid problems with
493 drivers that may take more than five second to associate
494
495 2005-10-27 - v0.4.6
496 * allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
497 RSN IE, but WPA IE would match with wpa_supplicant configuration
498 * added support for named configuration blobs in order to avoid having
499 to use file system for external files (e.g., certificates);
500 variables can be set to "blob://<blob name>" instead of file path to
501 use a named blob; supported fields: pac_file, client_cert,
502 private_key
503 * fixed RSN pre-authentication (it was broken in the clean up of WPA
504 state machine interface in v0.4.5)
505 * driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
506 sure the driver configures broadcast decryption correctly
507 * added ca_path (and ca_path2) configuration variables that can be used
508 to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
509 system-wide trusted CA list
510 * added support for starting wpa_supplicant without a configuration
511 file (-C argument must be used to set ctrl_interface parameter for
512 this case; in addition, -p argument can be used to provide
513 driver_param; these new arguments can also be used with a
514 configuration to override the values from the configuration)
515 * added global control interface that can be optionally used for adding
516 and removing network interfaces dynamically (-g command line argument
517 for both wpa_supplicant and wpa_cli) without having to restart
518 wpa_supplicant process
519 * wpa_gui:
520 - try to save configuration whenever something is modified
521 - added WEP key configuration
522 - added possibility to edit the current network configuration
523 * driver_ndis: fixed driver polling not to increase frequency on each
524 received EAPOL frame due to incorrectly cancelled timeout
525 * added simple configuration file examples (in examples subdirectory)
526 * fixed driver_wext.c to filter wireless events based on ifindex to
527 avoid interfaces receiving events from other interfaces
528 * delay sending initial EAPOL-Start couple of seconds to speed up
529 authentication for the most common case of Authenticator starting
530 EAP authentication immediately after association
531
532 2005-09-25 - v0.4.5
533 * added a workaround for clearing keys with ndiswrapper to allow
534 roaming from WPA enabled AP to plaintext one
535 * added docbook documentation (doc/docbook) that can be used to
536 generate, e.g., man pages
537 * l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
538 PF_PACKET in order to prepare for network devices that do not use
539 Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
540 * use receipt of EAPOL-Key frame as a lower layer success indication
541 for EAP state machine to allow recovery from dropped EAP-Success
542 frame
543 * cleaned up internal EAPOL frame processing by not including link
544 layer (Ethernet) header during WPA and EAPOL/EAP processing; this
545 header is added only when transmitted the frame; this makes it easier
546 to use wpa_supplicant on link layers that use different header than
547 Ethernet
548 * updated EAP-PSK to use draft 9 by default since this can now be
549 tested with hostapd; removed support for draft 3, including
550 server_nai configuration option from network blocks
551 * driver_wired: add PAE address to the multicast address list in order
552 to be able to receive EAPOL frames with drivers that do not include
553 these multicast addresses by default
554 * driver_wext: add support for WE-19
555 * added support for multiple configuration backends (CONFIG_BACKEND
556 option); currently, only 'file' is supported (i.e., the format used
557 in wpa_supplicant.conf)
558 * added support for updating configuration ('wpa_cli save_config');
559 this is disabled by default and can be enabled with global
560 update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
561 and wpa_gui to store the configuration changes in a permanent store
562 * added GET_NETWORK ctrl_iface command
563 (e.g., 'wpa_cli get_network 0 ssid')
564
565 2005-08-21 - v0.4.4
566 * replaced OpenSSL patch for EAP-FAST support
567 (openssl-tls-extensions.patch) with a more generic and correct
568 patch (the new patch is not compatible with the previous one, so the
569 OpenSSL library will need to be patched with the new patch in order
570 to be able to build wpa_supplicant with EAP-FAST support)
571 * added support for using Windows certificate store (through CryptoAPI)
572 for client certificate and private key operations (EAP-TLS)
573 (see wpa_supplicant.conf for more information on how to configure
574 this with private_key)
575 * ported wpa_gui to Windows
576 * added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
577 built with the open source version of the Qt4 for Windows
578 * allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
579 with drivers that do not support WPA
580 * ndis_events: fixed Windows 2000 support
581 * added support for enabling/disabling networks from the list of all
582 configured networks ('wpa_cli enable_network <network id>' and
583 'wpa_cli disable_network <network id>')
584 * added support for adding and removing network from the current
585 configuration ('wpa_cli add_network' and 'wpa_cli remove_network
586 <network id>'); added networks are disabled by default and they can
587 be enabled with enable_network command once the configuration is done
588 for the new network; note: configuration file is not yet updated, so
589 these new networks are lost when wpa_supplicant is restarted
590 * added support for setting network configuration parameters through
591 the control interface, for example:
592 wpa_cli set_network 0 ssid "\"my network\""
593 * fixed parsing of strings that include both " and # within double
594 quoted area (e.g., "start"#end")
595 * added EAP workaround for PEAP session resumption: allow outer,
596 i.e., not tunneled, EAP-Success to terminate session since; this can
597 be disabled with eap_workaround=0
598 (this was allowed for PEAPv1 before, but now it is also allowed for
599 PEAPv0 since at least one RADIUS authentication server seems to be
600 doing this for PEAPv0, too)
601 * wpa_gui: added preliminary support for adding new networks to the
602 wpa_supplicant configuration (double click on the scan results to
603 open network configuration)
604
605 2005-06-26 - v0.4.3
606 * removed interface for external EAPOL/EAP supplicant (e.g.,
607 Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
608 anymore and is unlikely to be used by anyone
609 * driver_ndis: fixed WinPcap 3.0 support
610 * fixed build with CONFIG_DNET_PCAP=y on Linux
611 * l2_packet: moved different implementations into separate files
612 (l2_packet_*.c)
613
614 2005-06-12 - v0.4.2
615 * driver_ipw: updated driver structures to match with ipw2200-1.0.4
616 (note: ipw2100-1.1.0 is likely to require an update to work with
617 this)
618 * added support for using ap_scan=2 mode with multiple network blocks;
619 wpa_supplicant will go through the networks one by one until the
620 driver reports a successful association; this uses the same order for
621 networks as scan_ssid=1 scans, i.e., the priority field is ignored
622 and the network block order in the file is used instead
623 * fixed a potential issue in RSN pre-authentication ending up using
624 freed memory if pre-authentication times out
625 * added support for matching alternative subject name extensions of the
626 authentication server certificate; new configuration variables
627 altsubject_match and altsubject_match2
628 * driver_ndis: added support for IEEE 802.1X authentication with wired
629 NDIS drivers
630 * added support for querying private key password (EAP-TLS) through the
631 control interface (wpa_cli/wpa_gui) if one is not included in the
632 configuration file
633 * driver_broadcom: fixed couple of memory leaks in scan result
634 processing
635 * EAP-PAX is now registered as EAP type 46
636 * fixed EAP-PAX MAC calculation
637 * fixed EAP-PAX CK and ICK key derivation
638 * added support for using password with EAP-PAX (as an alternative to
639 entering key with eappsk); SHA-1 hash of the password will be used as
640 the key in this case
641 * added support for arbitrary driver interface parameters through the
642 configuration file with a new driver_param field; this adds a new
643 driver_ops function set_param()
644 * added possibility to override l2_packet module with driver interface
645 API (new send_eapol handler); this can be used to implement driver
646 specific TX/RX functions for EAPOL frames
647 * fixed ctrl_interface_group processing for the case where gid is
648 entered as a number, not group name
649 * driver_test: added support for testing hostapd with wpa_supplicant
650 by using test driver interface without any kernel drivers or network
651 cards
652
653 2005-05-22 - v0.4.1
654 * driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
655 packets to be encrypted; this was apparently broken by the changed
656 ioctl order in v0.4.0
657 * driver_madwifi: added preliminary support for compiling against 'BSD'
658 branch of madwifi CVS tree
659 * added support for EAP-MSCHAPv2 password retries within the same EAP
660 authentication session
661 * added support for password changes with EAP-MSCHAPv2 (used when the
662 password has expired)
663 * added support for reading additional certificates from PKCS#12 files
664 and adding them to the certificate chain
665 * fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
666 were used
667 * fixed a possible double free in EAP-TTLS fast-reauthentication when
668 identity or password is entered through control interface
669 * display EAP Notification messages to user through control interface
670 with "CTRL-EVENT-EAP-NOTIFICATION" prefix
671 * added GUI version of wpa_cli, wpa_gui; this is not build
672 automatically with 'make'; use 'make wpa_gui' to build (this requires
673 Qt development tools)
674 * added 'disconnect' command to control interface for setting
675 wpa_supplicant in state where it will not associate before
676 'reassociate' command has been used
677 * added support for selecting a network from the list of all configured
678 networks ('wpa_cli select_network <network id>'; this disabled all
679 other networks; to re-enable, 'wpa_cli select_network any')
680 * added support for getting scan results through control interface
681 * added EAP workaround for PEAPv1 session resumption: allow outer,
682 i.e., not tunneled, EAP-Success to terminate session since; this can
683 be disabled with eap_workaround=0
684
685 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
686 * added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
687 used to reduce the size of the wpa_supplicant considerably if
688 debugging code is not needed
689 * fixed EAPOL-Key validation to drop packets with invalid Key Data
690 Length; such frames could have crashed wpa_supplicant due to buffer
691 overflow
692 * added support for wired authentication (IEEE 802.1X on wired
693 Ethernet); driver interface 'wired'
694 * obsoleted set_wpa() handler in the driver interface API (it can be
695 replaced by moving enable/disable functionality into init()/deinit())
696 (calls to set_wpa() are still present for backwards compatibility,
697 but they may be removed in the future)
698 * driver_madwifi: fixed association in plaintext mode
699 * modified the EAP workaround that accepts EAP-Success with incorrect
700 Identifier to be even less strict about verification in order to
701 interoperate with some authentication servers
702 * added support for sending TLS alerts
703 * added support for 'any' SSID wildcard; if ssid is not configured or
704 is set to an empty string, any SSID will be accepted for non-WPA AP
705 * added support for asking PIN (for SIM) from frontends (e.g.,
706 wpa_cli); if a PIN is needed, but not included in the configuration
707 file, a control interface request is sent and EAP processing is
708 delayed until the PIN is available
709 * added support for using external devices (e.g., a smartcard) for
710 private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
711 new wpa_supplicant.conf variables:
712 - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
713 - network: engine, engine_id, key_id
714 * added experimental support for EAP-PAX
715 * added monitor mode for wpa_cli (-a<path to a program to run>) that
716 allows external commands (e.g., shell scripts) to be run based on
717 wpa_supplicant events, e.g., when authentication has been completed
718 and data connection is ready; other related wpa_cli arguments:
719 -B (run in background), -P (write PID file); wpa_supplicant has a new
720 command line argument (-W) that can be used to make it wait until a
721 control interface command is received in order to avoid missing
722 events
723 * added support for opportunistic WPA2 PMKSA key caching (disabled by
724 default, can be enabled with proactive_key_caching=1)
725 * fixed RSN IE in 4-Way Handshake message 2/4 for the case where
726 Authenticator rejects PMKSA caching attempt and the driver is not
727 using assoc_info events
728 * added -P<pid file> argument for wpa_supplicant to write the current
729 process id into a file
730
731 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
732 * added new phase1 option parameter, include_tls_length=1, to force
733 wpa_supplicant to add TLS Message Length field to all TLS messages
734 even if the packet is not fragmented; this may be needed with some
735 authentication servers
736 * fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
737 using drivers that take care of AP selection (e.g., when using
738 ap_scan=2)
739 * fixed reprocessing of pending request after ctrl_iface requests for
740 identity/password/otp
741 * fixed ctrl_iface requests for identity/password/otp in Phase 2 of
742 EAP-PEAP and EAP-TTLS
743 * all drivers using driver_wext: set interface up and select Managed
744 mode when starting wpa_supplicant; set interface down when exiting
745 * renamed driver_ipw2100.c to driver_ipw.c since it now supports both
746 ipw2100 and ipw2200; please note that this also changed the
747 configuration variable in .config to CONFIG_DRIVER_IPW
748
749 2005-01-24 - v0.3.6
750 * fixed a busy loop introduced in v0.3.5 for scan result processing
751 when no matching AP is found
752
753 2005-01-23 - v0.3.5
754 * added a workaround for an interoperability issue with a Cisco AP
755 when using WPA2-PSK
756 * fixed non-WPA IEEE 802.1X to use the same authentication timeout as
757 WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
758 retransmission of dropped frames)
759 * fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
760 (e.g., segfault when processing EAPOL-Key frames)
761 * fixed EAP workaround and fast reauthentication configuration for
762 RSN pre-authentication; previously these were disabled and
763 pre-authentication would fail if the used authentication server
764 requires EAP workarounds
765 * added support for blacklisting APs that fail or timeout
766 authentication in ap_scan=1 mode so that all APs are tried in cases
767 where the ones with strongest signal level are failing authentication
768 * fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
769 authentication attempt
770 * allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
771 in the previous authentication (previously, only Phase 1 success was
772 verified)
773
774 2005-01-09 - v0.3.4
775 * added preliminary support for IBSS (ad-hoc) mode configuration
776 (mode=1 in network block); this included a new key_mgmt mode
777 WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
778 key management; see wpa_supplicant.conf for more details and an
779 example on how to configure this (note: this is currently implemented
780 only for driver_hostapd.c, but the changes should be trivial to add
781 in associate() handler for other drivers, too (assuming the driver
782 supports WPA-None)
783 * added preliminary port for native Windows (i.e., no cygwin) using
784 mingw
785
786 2005-01-02 - v0.3.3
787 * added optional support for GNU Readline and History Libraries for
788 wpa_cli (CONFIG_READLINE)
789 * cleaned up EAP state machine <-> method interface and number of
790 small problems with error case processing not terminating on
791 EAP-Failure but waiting for timeout
792 * added couple of workarounds for interoperability issues with a
793 Cisco AP when using WPA2
794 * added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
795 Note: This requires a patch for openssl to add support for TLS
796 extensions and number of workarounds for operations without
797 certificates. Proof of concept type of experimental patch is
798 included in openssl-tls-extensions.patch.
799
800 2004-12-19 - v0.3.2
801 * fixed private key loading for cases where passphrase is not set
802 * fixed Windows/cygwin L2 packet handler freeing; previous version
803 could cause a segfault when RSN pre-authentication was completed
804 * added support for PMKSA caching with drivers that generate RSN IEs
805 (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
806 but similar code can be easily added to driver_ndiswrapper.c once
807 ndiswrapper gets full support for RSN PMKSA caching
808 * improved recovery from PMKID mismatches by requesting full EAP
809 authentication in case of failed PMKSA caching attempt
810 * driver_ndis: added support for NDIS NdisMIncidateStatus() events
811 (this requires that ndis_events is ran while wpa_supplicant is
812 running)
813 * driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
814 * added support for driver interfaces to replace the interface name
815 based on driver/OS specific mapping, e.g., in case of driver_ndis,
816 this allows the beginning of the adapter description to be used as
817 the interface name
818 * added support for CR+LF (Windows-style) line ends in configuration
819 file
820 * driver_ndis: enable radio before starting scanning, disable radio
821 when exiting
822 * modified association event handler to set portEnabled = FALSE before
823 clearing port Valid in order to reset EAP state machine and avoid
824 problems with new authentication getting ignored because of state
825 machines ending up in AUTHENTICATED/SUCCESS state based on old
826 information
827 * added support for driver events to add PMKID candidates in order to
828 allow drivers to give priority to most likely roaming candidates
829 * driver_hostap: moved PrivacyInvoked configuration to associate()
830 function so that this will not be set for plaintext connections
831 * added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
832 interface can distinguish plaintext and IEEE 802.1X (no WPA)
833 authentication
834 * fixed static WEP key configuration to use broadcast/default type for
835 all keys (previously, the default TX key was configured as pairwise/
836 unicast key)
837 * driver_ndis: added legacy WPA capability detection for non-WPA2
838 drivers
839 * added support for setting static WEP keys for IEEE 802.1X without
840 dynamic WEP keying (eapol_flags=0)
841
842 2004-12-12 - v0.3.1
843 * added support for reading PKCS#12 (PFX) files (as a replacement for
844 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
845 * fixed compilation with CONFIG_PCSC=y
846 * added new ap_scan mode, ap_scan=2, for drivers that take care of
847 association, but need to be configured with security policy and SSID,
848 e.g., ndiswrapper and NDIS driver; this mode should allow such
849 drivers to work with hidden SSIDs and optimized roaming; when
850 ap_scan=2 is used, only the first network block in the configuration
851 file is used and this configuration should have explicit security
852 policy (i.e., only one option in the lists) for key_mgmt, pairwise,
853 group, proto variables
854 * added experimental port of wpa_supplicant for Windows
855 - driver_ndis.c driver interface (NDIS OIDs)
856 - currently, this requires cygwin and WinPcap
857 - small utility, win_if_list, can be used to get interface name
858 * control interface can now be removed at build time; add
859 CONFIG_CTRL_IFACE=y to .config to maintain old functionality
860 * optional Xsupplicant interface can now be removed at build time;
861 (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
862 * added auth_alg to driver interface associate() parameters to make it
863 easier for drivers to configure authentication algorithm as part of
864 the association
865
866 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
867 * driver_broadcom: added new driver interface for Broadcom wl.o driver
868 (a generic driver for Broadcom IEEE 802.11a/g cards)
869 * wpa_cli: fixed parsing of -p <path> command line argument
870 * PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
871 ACK, not tunneled EAP-Success (of which only the first byte was
872 actually send due to a bug in previous code); this seems to
873 interoperate with most RADIUS servers that implements PEAPv1
874 * PEAPv1: added support for terminating PEAP authentication on tunneled
875 EAP-Success message; this can be configured by adding
876 peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
877 (some RADIUS servers require this whereas others require a tunneled
878 reply
879 * PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
880 the old label for key derivation; previously, the default was 1,
881 but it looks like most existing PEAPv1 implementations use the old
882 label which is thus more suitable default option
883 * added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
884 * fixed parsing of wep_tx_keyidx
885 * added support for configuring list of allowed Phase 2 EAP types
886 (for both EAP-PEAP and EAP-TTLS) instead of only one type
887 * added support for configuring IEEE 802.11 authentication algorithm
888 (auth_alg; mainly for using Shared Key authentication with static
889 WEP keys)
890 * added support for EAP-AKA (with UMTS SIM)
891 * fixed couple of errors in PCSC handling that could have caused
892 random-looking errors for EAP-SIM
893 * added support for EAP-SIM pseudonyms and fast re-authentication
894 * added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
895 session resumption)
896 * added support for EAP-SIM with two challanges
897 (phase1="sim_min_num_chal=3" can be used to require three challenges)
898 * added support for configuring DH/DSA parameters for an ephemeral DH
899 key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
900 dh_file and dh_file2 (phase 2); this adds support for using DSA keys
901 and optional DH key exchange to achieve forward secracy with RSA keys
902 * added support for matching subject of the authentication server
903 certificate with a substring when using EAP-TLS/PEAP/TTLS; new
904 configuration variables subject_match and subject_match2
905 * changed SSID configuration in driver_wext.c (used by many driver
906 interfaces) to use ssid_len+1 as the length for SSID since some Linux
907 drivers expect this
908 * fixed couple of unaligned reads in scan result parsing to fix WPA
909 connection on some platforms (e.g., ARM)
910 * added driver interface for Intel ipw2100 driver
911 * added support for LEAP with WPA
912 * added support for larger scan results report (old limit was 4 kB of
913 data, i.e., about 35 or so APs) when using Linux wireless extensions
914 v17 or newer
915 * fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
916 only if there is a PMKSA cache entry for the current AP
917 * fixed error handling for case where reading of scan results fails:
918 must schedule a new scan or wpa_supplicant will remain waiting
919 forever
920 * changed debug output to remove shared password/key material by
921 default; all key information can be included with -K command line
922 argument to match the previous behavior
923 * added support for timestamping debug log messages (disabled by
924 default, can be enabled with -t command line argument)
925 * set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
926 if keys are not configured to be used; this fixes IEEE 802.1X mode
927 with drivers that use this information to configure whether Privacy
928 bit can be in Beacon frames (e.g., ndiswrapper)
929 * avoid clearing driver keys if no keys have been configured since last
930 key clear request; this seems to improve reliability of group key
931 handshake for ndiswrapper & NDIS driver which seems to be suffering
932 of some kind of timing issue when the keys are cleared again after
933 association
934 * changed driver interface API:
935 - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
936 version is being used (now, this is set to 2; previously, it was
937 not defined)
938 - pass pointer to private data structure to all calls
939 - the new API is not backwards compatible; all in-tree driver
940 interfaces has been converted to the new API
941 * added support for controlling multiple interfaces (radios) per
942 wpa_supplicant process; each interface needs to be listed on the
943 command line (-c, -i, -D arguments) with -N as a separator
944 (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
945 * added a workaround for EAP servers that incorrectly use same Id for
946 sequential EAP packets
947 * changed libpcap/libdnet configuration to use .config variable,
948 CONFIG_DNET_PCAP, instead of requiring Makefile modification
949 * improved downgrade attack detection in IE verification of msg 3/4:
950 verify both WPA and RSN IEs, if present, not only the selected one;
951 reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
952 Probe Response frame, and RSN is enabled in wpa_supplicant
953 configuration
954 * fixed WPA msg 3/4 processing to allow Key Data field contain other
955 IEs than just one WPA IE
956 * added support for FreeBSD and driver interface for the BSD net80211
957 layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
958 required kernel mods have not yet been committed
959 * made EAP workarounds configurable; enabled by default, can be
960 disabled with network block option eap_workaround=0
961
962 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
963 * resolved couple of interoperability issues with EAP-PEAPv1 and
964 Phase 2 (inner EAP) fragment reassembly
965 * driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
966 AP is using non-zero key index for the unicast key and key index zero
967 for the broadcast key
968 * driver_hostap: fixed IEEE 802.1X WEP key updates and
969 re-authentication by allowing unencrypted EAPOL frames when not using
970 WPA
971 * added a new driver interface, 'wext', which uses only standard,
972 driver independent functionality in Linux wireless extensions;
973 currently, this can be used only for non-WPA IEEE 802.1X mode, but
974 eventually, this is to be extended to support full WPA/WPA2 once
975 Linux wireless extensions get support for this
976 * added support for mode in which the driver is responsible for AP
977 scanning and selection; this is disabled by default and can be
978 enabled with global ap_scan=0 variable in wpa_supplicant.conf;
979 this mode can be used, e.g., with generic 'wext' driver interface to
980 use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
981 supporting wireless extensions.
982 * driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
983 operation with an AP that does not include SSID in the Beacon frames)
984 * added support for new EAP authentication methods:
985 EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
986 * added support for asking one-time-passwords from frontends (e.g.,
987 wpa_cli); this 'otp' command works otherwise like 'password' command,
988 but the password is used only once and the frontend will be asked for
989 a new password whenever a request from authenticator requires a
990 password; this can be used with both EAP-OTP and EAP-GTC
991 * changed wpa_cli to automatically re-establish connection so that it
992 does not need to be re-started when wpa_supplicant is terminated and
993 started again
994 * improved user data (identity/password/otp) requests through
995 frontends: process pending EAPOL packets after getting new
996 information so that full authentication does not need to be
997 restarted; in addition, send pending requests again whenever a new
998 frontend is attached
999 * changed control frontends to use a new directory for socket files to
1000 make it easier for wpa_cli to automatically select between interfaces
1001 and to provide access control for the control interface;
1002 wpa_supplicant.conf: ctrl_interface is now a path
1003 (/var/run/wpa_supplicant is the recommended path) and
1004 ctrl_interface_group can be used to select which group gets access to
1005 the control interface;
1006 wpa_cli: by default, try to connect to the first interface available
1007 in /var/run/wpa_supplicant; this path can be overriden with -p option
1008 and an interface can be selected with -i option (i.e., in most common
1009 cases, wpa_cli does not need to get any arguments)
1010 * added support for LEAP
1011 * added driver interface for Linux ndiswrapper
1012 * added priority option for network blocks in the configuration file;
1013 this allows networks to be grouped based on priority (the scan
1014 results are searched for matches with network blocks in this order)
1015
1016 2004-06-20 - v0.2.3
1017 * sort scan results to improve AP selection
1018 * fixed control interface socket removal for some error cases
1019 * improved scan requesting and authentication timeout
1020 * small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1021 TLS processing
1022 * PEAP version can now be forced with phase1="peapver=<ver>"
1023 (mostly for testing; by default, the highest version supported by
1024 both the Supplicant and Authentication Server is selected
1025 automatically)
1026 * added support for madwifi driver (Atheros ar521x)
1027 * added a workaround for cases where AP sets Install Tx/Rx bit for
1028 WPA Group Key messages when pairwise keys are used (without this,
1029 the Group Key would be used for Tx and the AP would drop frames
1030 from the station)
1031 * added GSM SIM/USIM interface for GSM authentication algorithm for
1032 EAP-SIM; this requires pcsc-lite
1033 * added support for ATMEL AT76C5XXx driver
1034 * fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1035 does not include key data in the EAPOL-Key frame (i.e., part of
1036 EAP keying material is used as data encryption key)
1037 * added support for using plaintext and static WEP networks
1038 (key_mgmt=NONE)
1039
1040 2004-05-31 - v0.2.2
1041 * added support for new EAP authentication methods:
1042 EAP-TTLS/EAP-MD5-Challenge
1043 EAP-TTLS/EAP-GTC
1044 EAP-TTLS/EAP-MSCHAPv2
1045 EAP-TTLS/EAP-TLS
1046 EAP-TTLS/MSCHAPv2
1047 EAP-TTLS/MSCHAP
1048 EAP-TTLS/PAP
1049 EAP-TTLS/CHAP
1050 EAP-PEAP/TLS
1051 EAP-PEAP/GTC
1052 EAP-PEAP/MD5-Challenge
1053 EAP-GTC
1054 EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1055 * added support for anonymous identity (to be used when identity is
1056 sent in plaintext; real identity will be used within TLS protected
1057 tunnel (e.g., with EAP-TTLS)
1058 * added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1059 * added support for requesting identity and password information using
1060 control interface; in other words, the password for EAP-PEAP or
1061 EAP-TTLS does not need to be included in the configuration file since
1062 a frontand (e.g., wpa_cli) can ask it from the user
1063 * improved RSN pre-authentication to use a candidate list and process
1064 all candidates from each scan; not only one per scan
1065 * fixed RSN IE and WPA IE capabilities field parsing
1066 * ignore Tx bit in GTK IE when Pairwise keys are used
1067 * avoid making new scan requests during IEEE 802.1X negotiation
1068 * use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1069 with TLS support (this replaces the included implementation with
1070 library code to save about 8 kB since the library code is needed
1071 anyway for TLS)
1072 * fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1073 (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1074
1075 2004-05-06 - v0.2.1
1076 * added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1077 Supplicant
1078 - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1079 - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1080 - EAP-MD5 (cannot be used with WPA-RADIUS)
1081 [draft-ietf-eap-rfc2284bis-09.txt]
1082 - EAP-TLS [RFC 2716]
1083 - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1084 - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1085 [draft-kamath-pppext-eap-mschapv2-00.txt]
1086 (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1087 default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1088 - new configuration file options: eap, identity, password, ca_cert,
1089 client_cert, privatekey, private_key_passwd
1090 - Xsupplicant is not required anymore, but it can be used by
1091 disabling the internal IEEE 802.1X Supplicant with -e command line
1092 option
1093 - this code is not included in the default build; Makefile need to
1094 be edited for this (uncomment lines for selected functionality)
1095 - EAP-TLS and EAP-PEAP require openssl libraries
1096 * use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1097 * added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1098 (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1099 EAPOL-Key frames instead of WPA key handshakes)
1100 * added support for IEEE 802.11i/RSN (WPA2)
1101 - improved PTK Key Handshake
1102 - PMKSA caching, pre-authentication
1103 * fixed wpa_supplicant to ignore possible extra data after WPA
1104 EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
1105 TPTK' error from message 3 of 4-Way Handshake in case the AP
1106 includes extra data after the EAPOL-Key)
1107 * added interface for external programs (frontends) to control
1108 wpa_supplicant
1109 - CLI example (wpa_cli) with interactive mode and command line
1110 mode
1111 - replaced SIGUSR1 status/statistics with the new control interface
1112 * made some feature compile time configurable
1113 - .config file for make
1114 - driver interfaces (hostap, hermes, ..)
1115 - EAPOL/EAP functions
1116
1117 2004-02-15 - v0.2.0
1118 * Initial version of wpa_supplicant
