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