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