1ChangeLog for wpa_supplicant
2
32010-01-12 - v0.6.10
4	* fixed SHA-256 based key derivation function to match with the
5	  standard when using CCMP (for IEEE 802.11r and IEEE 802.11w)
6	  (note: this breaks interoperability with previous version) [Bug 307]
7	* changed driver_wext to disconnect at init/deinit to clear state
8	* added explicit disconnect on 4-way handshake failures
9	* added WPS workarounds for known interoperability issues with broken,
10	  deployed implementation
11	* update IEEE 802.11w implementation to match with the published
12	  standard
13	* do not send WPS M8 message when learning current AP configuration as
14	  an external Registrar
15	* added a workaround for race condition between receive EAPOL frames
16	  and association events
17	* fixed compilation with newer GnuTLS versions
18	* fixed PKCS#12 use with OpenSSL 1.0.0
19
202009-03-23 - v0.6.9
21	* driver_ndis: add PAE group address to the multicast address list to
22	  fix wired IEEE 802.1X authentication
23	* fixed IEEE 802.11r key derivation function to match with the standard
24	  (note: this breaks interoperability with previous version) [Bug 303]
25
262009-02-15 - v0.6.8
27	* increased wpa_cli ping interval to 5 seconds and made this
28	  configurable with a new command line options (-G<seconds>)
29	* fixed scan buffer processing with WEXT to handle up to 65535
30	  byte result buffer (previously, limited to 32768 bytes)
31
322009-01-06 - v0.6.7
33	* added support for Wi-Fi Protected Setup (WPS)
34	  (wpa_supplicant can now be configured to act as a WPS Enrollee to
35	  enroll credentials for a network using PIN and PBC methods; in
36	  addition, wpa_supplicant can act as a wireless WPS Registrar to
37	  configure an AP); WPS support can be enabled by adding CONFIG_WPS=y
38	  into .config and setting the runtime configuration variables in
39	  wpa_supplicant.conf (see WPS section in the example configuration
40	  file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to
41	  manage WPS negotiation; see README-WPS for more details
42	* added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
43	* added support for using driver_test over UDP socket
44	* fixed PEAPv0 Cryptobinding interoperability issue with Windows Server
45	  2008 NPS; optional cryptobinding is now enabled (again) by default
46	* fixed PSK editing in wpa_gui
47	* changed EAP-GPSK to use the IANA assigned EAP method type 51
48	* added a Windows installer that includes WinPcap and all the needed
49	  DLLs; in addition, it set up the registry automatically so that user
50	  will only need start wpa_gui to get prompted to start the wpasvc
51	  servide and add a new interface if needed through wpa_gui dialog
52	* updated management frame protection to use IEEE 802.11w/D7.0
53
542008-11-23 - v0.6.6
55	* added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
56	  (can be used to simulate test SIM/USIM card with a known private key;
57	  enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
58	  and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
59	* added a new network configuration option, wpa_ptk_rekey, that can be
60	  used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
61	  against TKIP deficiencies
62	* added an optional mitigation mechanism for certain attacks against
63	  TKIP by delaying Michael MIC error reports by a random amount of time
64	  between 0 and 60 seconds; this can be enabled with a build option
65	  CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
66	* fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
67	  not bytes
68	* updated OpenSSL code for EAP-FAST to use an updated version of the
69	  session ticket overriding API that was included into the upstream
70	  OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
71	  needed with that version anymore)
72	* updated userspace MLME instructions to match with the current Linux
73	  mac80211 implementation; please also note that this can only be used
74	  with driver_nl80211.c (the old code from driver_wext.c was removed)
75	* added support (Linux only) for RoboSwitch chipsets (often found in
76	  consumer grade routers); driver interface 'roboswitch'
77	* fixed canceling of PMKSA caching when using drivers that generate
78	  RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
79	  about
80
812008-11-01 - v0.6.5
82	* added support for SHA-256 as X.509 certificate digest when using the
83	  internal X.509/TLSv1 implementation
84	* updated management frame protection to use IEEE 802.11w/D6.0
85	* added support for using SHA256-based stronger key derivation for WPA2
86	  (IEEE 802.11w)
87	* fixed FT (IEEE 802.11r) authentication after a failed association to
88	  use correct FTIE
89	* added support for configuring Phase 2 (inner/tunneled) authentication
90	  method with wpa_gui-qt4
91
922008-08-10 - v0.6.4
93	* added support for EAP Sequences in EAP-FAST Phase 2
94	* added support for using TNC with EAP-FAST
95	* added driver_ps3 for the PS3 Linux wireless driver
96	* added support for optional cryptobinding with PEAPv0
97	* fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
98	  allow fallback to full handshake if server rejects PAC-Opaque
99	* added fragmentation support for EAP-TNC
100	* added support for parsing PKCS #8 formatted private keys into the
101	  internal TLS implementation (both PKCS #1 RSA key and PKCS #8
102	  encapsulated RSA key can now be used)
103	* added option of using faster, but larger, routines in the internal
104	  LibTomMath (for internal TLS implementation) to speed up DH and RSA
105	  calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
106	* fixed race condition between disassociation event and group key
107	  handshake to avoid getting stuck in incorrect state [Bug 261]
108	* fixed opportunistic key caching (proactive_key_caching)
109
1102008-02-22 - v0.6.3
111	* removed 'nai' and 'eappsk' network configuration variables that were
112	  previously used for configuring user identity and key for EAP-PSK,
113	  EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
114	  replacement for 'nai' (if old configuration used a separate
115	  'identity' value, that would now be configured as
116	  'anonymous_identity'). 'password' field is now used as the
117	  replacement for 'eappsk' (it can also be set using hexstring to
118	  present random binary data)
119	* removed '-w' command line parameter (wait for interface to be added,
120	  if needed); cleaner way of handling this functionality is to use an
121	  external mechanism (e.g., hotplug scripts) that start wpa_supplicant
122	  when an interface is added
123	* updated FT support to use the latest draft, IEEE 802.11r/D9.0
124	* added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
125	  indicating when new scan results become available
126	* added new ctrl_iface command, BSS, to allow scan results to be
127	  fetched without hitting the message size limits (this command
128	  can be used to iterate through the scan results one BSS at the time)
129	* fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
130	  attributes in EAP-SIM Start/Response when using fast reauthentication
131	* fixed EAPOL not to end up in infinite loop when processing dynamic
132	  WEP keys with IEEE 802.1X
133	* fixed problems in getting NDIS events from WMI on Windows 2000
134
1352008-01-01 - v0.6.2
136	* added support for Makefile builds to include debug-log-to-a-file
137	  functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
138	* fixed EAP-SIM and EAP-AKA message parser to validate attribute
139	  lengths properly to avoid potential crash caused by invalid messages
140	* added data structure for storing allocated buffers (struct wpabuf);
141	  this does not affect wpa_supplicant usage, but many of the APIs
142	  changed and various interfaces (e.g., EAP) is not compatible with old
143	  versions
144	* added support for protecting EAP-AKA/Identity messages with
145	  AT_CHECKCODE (optional feature in RFC 4187)
146	* added support for protected result indication with AT_RESULT_IND for
147	  EAP-SIM and EAP-AKA (phase1="result_ind=1")
148	* added driver_wext workaround for race condition between scanning and
149	  association with drivers that take very long time to scan all
150	  channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
151	  using a longer hardcoded timeout for the scan if the driver supports
152	  notifications for scan completion (SIOCGIWSCAN event); this helps,
153	  e.g., in cases where wpa_supplicant and madwifi driver ended up in
154	  loop where the driver did not even try to associate
155	* stop EAPOL timer tick when no timers are in use in order to reduce
156	  power consumption (no need to wake up the process once per second)
157	  [Bug 237]
158	* added support for privilege separation (run only minimal part of
159	  wpa_supplicant functionality as root and rest as unprivileged,
160	  non-root process); see 'Privilege separation' in README for details;
161	  this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
162	  in .config
163	* changed scan results data structure to include all information
164	  elements to make it easier to support new IEs; old get_scan_result()
165	  driver_ops is still supported for backwards compatibility (results
166	  are converted internally to the new format), but all drivers should
167	  start using the new get_scan_results2() to make them more likely to
168	  work with new features
169	* Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
170	  application, i.e., it does not require Qt3Support anymore; Windows
171	  binary of wpa_gui.exe is now from this directory and only requires
172	  QtCore4.dll and QtGui4.dll libraries
173	* updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
174	  available as a separate package to make wpa_gui installation easier:
175	  http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
176	* added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
177	  only shared key/password authentication is supported in this version
178
1792007-11-24 - v0.6.1
180	* added support for configuring password as NtPasswordHash
181	  (16-byte MD4 hash of password) in hash:<32 hex digits> format
182	* added support for fallback from abbreviated TLS handshake to
183	  full handshake when using EAP-FAST (e.g., due to an expired
184	  PAC-Opaque)
185	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
186	  draft (draft-ietf-emu-eap-gpsk-07.txt)
187	* added support for drivers that take care of RSN 4-way handshake
188	  internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
189	  WPA_ALG_PMK in set_key)
190	* added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
191	  .config); this version supports only ap_scan=2 mode and allow the
192	  driver to take care of the 4-way handshake
193	* fixed a buffer overflow in parsing TSF from scan results when using
194	  driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
195	  [Bug 232]
196	* updated FT support to use the latest draft, IEEE 802.11r/D8.0
197	* fixed an integer overflow issue in the ASN.1 parser used by the
198	  (experimental) internal TLS implementation to avoid a potential
199	  buffer read overflow
200	* fixed a race condition with -W option (wait for a control interface
201	  monitor before starting) that could have caused the first messages to
202	  be lost
203	* added support for processing TNCC-TNCS-Messages to report
204	  recommendation (allow/none/isolate) when using TNC [Bug 243]
205
2062007-05-28 - v0.6.0
207	* added network configuration parameter 'frequency' for setting
208	  initial channel for IBSS (adhoc) networks
209	* added experimental IEEE 802.11r/D6.0 support
210	* updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
211	* updated EAP-PSK to use the IANA-allocated EAP type 47
212	* fixed EAP-PAX key derivation
213	* fixed EAP-PSK bit ordering of the Flags field
214	* fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
215	  tunnelled identity request (previously, the identifier from the outer
216	  method was used, not the tunnelled identifier which could be
217	  different)
218	* added support for fragmentation of outer TLS packets during Phase 2
219	  of EAP-PEAP/TTLS/FAST
220	* fixed EAP-TTLS AVP parser processing for too short AVP lengths
221	* added support for EAP-FAST authentication with inner methods that
222	  generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
223	  for PAC provisioning)
224	* added support for authenticated EAP-FAST provisioning
225	* added support for configuring maximum number of EAP-FAST PACs to
226	  store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
227	* added support for storing EAP-FAST PACs in binary format
228	  (fast_pac_format=binary in phase1 string)
229	* fixed dbus ctrl_iface to validate message interface before
230	  dispatching to avoid a possible segfault [Bug 190]
231	* fixed PeerKey key derivation to use the correct PRF label
232	* updated Windows binary build to link against OpenSSL 0.9.8d and
233	  added support for EAP-FAST
234	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
235	  draft (draft-ietf-emu-eap-gpsk-04.txt)
236	* fixed EAP-AKA Notification processing to allow Notification to be
237	  processed after AKA Challenge response has been sent
238	* updated to use IEEE 802.11w/D2.0 for management frame protection
239	  (still experimental)
240	* fixed EAP-TTLS implementation not to crash on use of freed memory
241	  if TLS library initialization fails
242	* added support for EAP-TNC (Trusted Network Connect)
243	  (this version implements the EAP-TNC method and EAP-TTLS changes
244	  needed to run two methods in sequence (IF-T) and the IF-IMC and
245	  IF-TNCCS interfaces from TNCC)
246
2472006-11-24 - v0.5.6
248	* added experimental, integrated TLSv1 client implementation with the
249	  needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
250	  setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
251	  .config); this can be useful, e.g., if the target system does not
252	  have a suitable TLS library and a minimal code size is required
253	  (total size of this internal TLS/crypto code is bit under 50 kB on
254	  x86 and the crypto code is shared by rest of the supplicant so some
255	  of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
256	* removed STAKey handshake since PeerKey handshake has replaced it in
257	  IEEE 802.11ma and there are no known deployments of STAKey
258	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
259	  draft (draft-ietf-emu-eap-gpsk-01.txt)
260	* added preliminary implementation of IEEE 802.11w/D1.0 (management
261	  frame protection)
262	  (Note: this requires driver support to work properly.)
263	  (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
264	* fixed Windows named pipes ctrl_iface to not stop listening for
265	  commands if client program opens a named pipe and closes it
266	  immediately without sending a command
267	* fixed USIM PIN status determination for the case that PIN is not
268	  needed (this allows EAP-AKA to be used with USIM cards that do not
269	  use PIN)
270	* added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
271	  be used with cards that do not support file selection based on
272	  partial AID
273	* added support for matching the subjectAltName of the authentication
274	  server certificate against multiple name components (e.g.,
275	  altsubject_match="DNS:server.example.com;DNS:server2.example.com")
276	* fixed EAP-SIM/AKA key derivation for re-authentication case (only
277	  affects IEEE 802.1X with dynamic WEP keys)
278	* changed ctrl_iface network configuration 'get' operations to not
279	  return password/key material; if these fields are requested, "*"
280	  will be returned if the password/key is set, but the value of the
281	  parameter is not exposed
282
2832006-08-27 - v0.5.5
284	* added support for building Windows version with UNICODE defined
285	  (wide-char functions)
286	* driver_ndis: fixed static WEP configuration to avoid race condition
287	  issues with some NDIS drivers between association and setting WEP
288	  keys
289	* driver_ndis: added validation for IELength value in scan results to
290	  avoid crashes when using buggy NDIS drivers [Bug 165]
291	* fixed Release|Win32 target in the Visual Studio project files
292	  (previously, only Debug|Win32 target was set properly)
293	* changed control interface API call wpa_ctrl_pending() to allow it to
294	  return -1 on error (e.g., connection lost); control interface clients
295	  will need to make sure that they verify that the value is indeed >0
296	  when determining whether there are pending messages
297	* added an alternative control interface backend for Windows targets:
298	  Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
299	  control interface mechanism for Windows builds (previously, UDP to
300	  localhost was used)
301	* changed ctrl_interface configuration for UNIX domain sockets:
302	  - deprecated ctrl_interface_group variable (it may be removed in
303	    future versions)
304	  - allow both directory and group be configured with ctrl_interface
305	    in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
306	  - ctrl_interface=/var/run/wpa_supplicant is still supported for the
307	    case when group is not changed
308	* added support for controlling more than one interface per process in
309	  Windows version
310	* added a workaround for a case where the AP is using unknown address
311	  (e.g., MAC address of the wired interface) as the source address for
312	  EAPOL-Key frames; previously, that source address was used as the
313	  destination for EAPOL-Key frames and in key derivation; now, BSSID is
314	  used even if the source address does not match with it
315	  (this resolves an interoperability issue with Thomson SpeedTouch 580)
316	* added a workaround for UDP-based control interface (which was used in
317	  Windows builds before this release) to prevent packets with forged
318	  addresses from being accepted as local control requests
319	* removed ndis_events.cpp and possibility of using external
320	  ndis_events.exe; C version (ndis_events.c) is fully functional and
321	  there is no desire to maintain two separate versions of this
322	  implementation
323	* ndis_events: Changed NDIS event notification design to use WMI to
324	  learn the adapter description through Win32_PnPEntity class; this
325	  should fix some cases where the adapter name was not recognized
326	  correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
327	  USB) [Bug 113]
328	* fixed selection of the first network in ap_scan=2 mode; previously,
329	  wpa_supplicant could get stuck in SCANNING state when only the first
330	  network for enabled (e.g., after 'wpa_cli select_network 0')
331	* winsvc: added support for configuring ctrl_interface parameters in
332	  registry (ctrl_interface string value in
333	  HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
334	  required to enable control interface (previously, this was hardcoded
335	  to be enabled)
336	* allow wpa_gui subdirectory to be built with both Qt3 and Qt4
337	* converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
338
3392006-06-20 - v0.5.4
340	* fixed build with CONFIG_STAKEY=y [Bug 143]
341	* added support for doing MLME (IEEE 802.11 management frame
342	  processing) in wpa_supplicant when using Devicescape IEEE 802.11
343	  stack (wireless-dev.git tree)
344	* added a new network block configuration option, fragment_size, to
345	  configure the maximum EAP fragment size
346	* driver_ndis: Disable WZC automatically for the selected interface to
347	  avoid conflicts with two programs trying to control the radio; WZC
348	  will be re-enabled (if it was enabled originally) when wpa_supplicant
349	  is terminated
350	* added an experimental TLSv1 client implementation
351	  (CONFIG_TLS=internal) that can be used instead of an external TLS
352	  library, e.g., to reduce total size requirement on systems that do
353	  not include any TLS library by default (this is not yet complete;
354	  basic functionality is there, but certificate validation is not yet
355	  included)
356	* added PeerKey handshake implementation for IEEE 802.11e
357	  direct link setup (DLS) to replace STAKey handshake
358	* fixed WPA PSK update through ctrl_iface for the case where the old
359	  PSK was derived from an ASCII passphrase and the new PSK is set as
360	  a raw PSK (hex string)
361	* added new configuration option for identifying which network block
362	  was used (id_str in wpa_supplicant.conf; included on
363	  WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
364	  variable in wpa_cli action scripts; in addition WPA_ID variable is
365	  set to the current unique identifier that wpa_supplicant assigned
366	  automatically for the network and that can be used with
367	  GET_NETWORK/SET_NETWORK ctrl_iface commands)
368	* wpa_cli action script is now called only when the connect/disconnect
369	  status changes or when associating with a different network
370	* fixed configuration parser not to remove CCMP from group cipher list
371	  if WPA-None (adhoc) is used (pairwise=NONE in that case)
372	* fixed integrated NDIS events processing not to hang the process due
373	  to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
374	* added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
375	  draft-clancy-emu-eap-shared-secret-00.txt)
376	* added Microsoft Visual Studio 2005 solution and project files for
377	  build wpa_supplicant for Windows (see vs2005 subdirectory)
378	* eloop_win: fixed unregistration of Windows events
379	* l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
380	  at the end of RSN pre-authentication and added unregistration of
381	  a Windows event to avoid getting eloop_win stuck with an invalid
382	  handle
383	* driver_ndis: added support for selecting AP based on BSSID
384	* added new environmental variable for wpa_cli action scripts:
385	  WPA_CTRL_DIR is the current control interface directory
386	* driver_ndis: added support for using NDISUIO instead of WinPcap for
387	  OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
388	  l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
389	  wpa_supplicant without requiring WinPcap; note that using NDISUIO
390	  requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
391	  only one application to open the device
392	* changed NDIS driver naming to only include device GUID, e.g.,
393	  {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
394	  specific \Device\NPF_ prefix before the GUID; the prefix is still
395	  allowed for backwards compatibility, but it is not required anymore
396	  when specifying the interface
397	* driver_ndis: re-initialize driver interface is the adapter is removed
398	  and re-inserted [Bug 159]
399	* driver_madwifi: fixed TKIP and CCMP sequence number configuration on
400	  big endian hosts [Bug 146]
401
4022006-04-27 - v0.5.3
403	* fixed EAP-GTC response to include correct user identity when run as
404	  phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
405	* driver_ndis: Fixed encryption mode configuration for unencrypted
406	  networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
407	  refused to associate with open networks) [Bug 106]
408	* driver_ndis: use BSSID OID polling to detect when IBSS network is
409	  formed even when ndis_events code is included since some NDIS drivers
410	  do not generate media connect events in IBSS mode
411	* config_winreg: allow global ctrl_interface parameter to be configured
412	  in Windows registry
413	* config_winreg: added support for saving configuration data into
414	  Windows registry
415	* added support for controlling network device operational state
416	  (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
417	  http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
418	  that can use this information)
419	* driver_wext: added support for WE-21 change to SSID configuration
420	* driver_wext: fixed privacy configuration for static WEP keys mode
421	  [Bug 140]
422	* added an optional driver_ops callback for MLME-SETPROTECTION.request
423	  primitive
424	* added support for EAP-SAKE (no EAP method number allocated yet, so
425	  this is using the same experimental type 255 as EAP-PSK)
426	* added support for dynamically loading EAP methods (.so files) instead
427	  of requiring them to be statically linked in; this is disabled by
428	  default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
429	  on how to use this)
430
4312006-03-19 - v0.5.2
432	* do not try to use USIM APDUs when initializing PC/SC for SIM card
433	  access for a network that has not enabled EAP-AKA
434	* fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
435	  v0.5.1 due to the new support for expanded EAP types)
436	* added support for generating EAP Expanded Nak
437	* try to fetch scan results once before requesting new scan when
438	  starting up in ap_scan=1 mode (this can speed up initial association
439	  a lot with, e.g., madwifi-ng driver)
440	* added support for receiving EAPOL frames from a Linux bridge
441	  interface (-bbr0 on command line)
442	* fixed EAPOL re-authentication for sessions that used PMKSA caching
443	* changed EAP method registration to use a dynamic list of methods
444	  instead of a static list generated at build time
445	* fixed PMKSA cache deinitialization not to use freed memory when
446	  removing PMKSA entries
447	* fixed a memory leak in EAP-TTLS re-authentication
448	* reject WPA/WPA2 message 3/4 if it does not include any valid
449	  WPA/RSN IE
450	* driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
451	  if the driver does not support SIOCSIWAUTH
452
4532006-01-29 - v0.5.1
454	* driver_test: added better support for multiple APs and STAs by using
455	  a directory with sockets that include MAC address for each device in
456	  the name (driver_param=test_dir=/tmp/test)
457	* added support for EAP expanded type (vendor specific EAP methods)
458	* added AP_SCAN command into ctrl_iface so that ap_scan configuration
459	  option can be changed if needed
460	* wpa_cli/wpa_gui: skip non-socket files in control directory when
461	  using UNIX domain sockets; this avoids selecting an incorrect
462	  interface (e.g., a PID file could be in this directory, even though
463	  use of this directory for something else than socket files is not
464	  recommended)
465	* fixed TLS library deinitialization after RSN pre-authentication not
466	  to disable TLS library for normal authentication
467	* driver_wext: Remove null-termination from SSID length if the driver
468	  used it; some Linux drivers do this and they were causing problems in
469	  wpa_supplicant not finding matching configuration block. This change
470	  would break a case where the SSID actually ends in '\0', but that is
471	  not likely to happen in real use.
472	* fixed PMKSA cache processing not to trigger deauthentication if the
473	  current PMKSA cache entry is replaced with a valid new entry
474	* fixed PC/SC initialization for ap_scan != 1 modes (this fixes
475	  EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
476	  ap_scan=2)
477
4782005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
479	* added experimental STAKey handshake implementation for IEEE 802.11e
480	  direct link setup (DLS); note: this is disabled by default in both
481	  build and runtime configuration (can be enabled with CONFIG_STAKEY=y
482	  and stakey=1)
483	* fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
484	  decrypt AT_ENCR_DATA attributes correctly
485	* fixed EAP-AKA to allow resynchronization within the same session
486	* made code closer to ANSI C89 standard to make it easier to port to
487	  other C libraries and compilers
488	* started moving operating system or C library specific functions into
489	  wrapper functions defined in os.h and implemented in os_*.c to make
490	  code more portable
491	* wpa_supplicant can now be built with Microsoft Visual C++
492	  (e.g., with the freely available Toolkit 2003 version or Visual
493	  C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
494	  example makefile for nmake
495	* added support for using Windows registry for command line parameters
496	  (CONFIG_MAIN=main_winsvc) and configuration data
497	  (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
498	  contents; this version can be run both as a Windows service and as a
499	  normal application; 'wpasvc.exe app' to start as applicant,
500	  'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
501	  'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
502	  unregister a service
503	* made it possible to link ndis_events.exe functionality into
504	  wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
505	* added better support for multiple control interface backends
506	  (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
507	* fixed PC/SC code to use correct length for GSM AUTH command buffer
508	  and to not use pioRecvPci with SCardTransmit() calls; these were not
509	  causing visible problems with pcsc-lite, but Windows Winscard.dll
510	  refused the previously used parameters; this fixes EAP-SIM and
511	  EAP-AKA authentication using SIM/USIM card under Windows
512	* added new event loop implementation for Windows using
513	  WaitForMultipleObject() instead of select() in order to allow waiting
514	  for non-socket objects; this can be selected with
515	  CONFIG_ELOOP=eloop_win in .config
516	* added support for selecting l2_packet implementation in .config
517	  (CONFIG_L2_PACKET; following options are available now: linux, pcap,
518	  winpcap, freebsd, none)
519	* added new l2_packet implementation for WinPcap
520	  (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
521	  reduce latency in EAPOL receive processing from about 100 ms to about
522	  3 ms
523	* added support for EAP-FAST key derivation using other ciphers than
524	  RC4-128-SHA for authentication and AES128-SHA for provisioning
525	* added support for configuring CA certificate as DER file and as a
526	  configuration blob
527	* fixed private key configuration as configuration blob and added
528	  support for using PKCS#12 as a blob
529	* tls_gnutls: added support for using PKCS#12 files; added support for
530	  session resumption
531	* added support for loading trusted CA certificates from Windows
532	  certificate store: ca_cert="cert_store://<name>", where <name> is
533	  likely CA (Intermediate CA certificates) or ROOT (root certificates)
534	* added C version of ndis_events.cpp and made it possible to build this
535	  with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
536	  easily on cross-compilation builds
537	* added wpasvc.exe into Windows binary release; this is an alternative
538	  version of wpa_supplicant.exe with configuration backend using
539	  Windows registry and with the entry point designed to run as a
540	  Windows service
541	* integrated ndis_events.exe functionality into wpa_supplicant.exe and
542	  wpasvc.exe and removed this additional tool from the Windows binary
543	  release since it is not needed anymore
544	* load winscard.dll functions dynamically when building with MinGW
545	  since MinGW does not yet include winscard library
546
5472005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
548	* l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
549	  and WinPcap to receive frames sent to PAE group address
550	* disable EAP state machine when IEEE 802.1X authentication is not used
551	  in order to get rid of bogus "EAP failed" messages
552	* fixed OpenSSL error reporting to go through all pending errors to
553	  avoid confusing reports of old errors being reported at later point
554	  during handshake
555	* fixed configuration file updating to not write empty variables
556	  (e.g., proto or key_mgmt) that the file parser would not accept
557	* fixed ADD_NETWORK ctrl_iface command to use the same default values
558	  for variables as empty network definitions read from config file
559	  would get
560	* fixed EAP state machine to not discard EAP-Failure messages in many
561	  cases (e.g., during TLS handshake)
562	* fixed a infinite loop in private key reading if the configured file
563	  cannot be parsed successfully
564	* driver_madwifi: added support for madwifi-ng
565	* wpa_gui: do not display password/PSK field contents
566	* wpa_gui: added CA certificate configuration
567	* driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
568	* driver_ndis: include Beacon IEs in AssocInfo in order to notice if
569	  the new AP is using different WPA/RSN IE
570	* use longer timeout for IEEE 802.11 association to avoid problems with
571	  drivers that may take more than five second to associate
572
5732005-10-27 - v0.4.6
574	* allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
575	  RSN IE, but WPA IE would match with wpa_supplicant configuration
576	* added support for named configuration blobs in order to avoid having
577	  to use file system for external files (e.g., certificates);
578	  variables can be set to "blob://<blob name>" instead of file path to
579	  use a named blob; supported fields: pac_file, client_cert,
580	  private_key
581	* fixed RSN pre-authentication (it was broken in the clean up of WPA
582	  state machine interface in v0.4.5)
583	* driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
584	  sure the driver configures broadcast decryption correctly
585	* added ca_path (and ca_path2) configuration variables that can be used
586	  to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
587	  system-wide trusted CA list
588	* added support for starting wpa_supplicant without a configuration
589	  file (-C argument must be used to set ctrl_interface parameter for
590	  this case; in addition, -p argument can be used to provide
591	  driver_param; these new arguments can also be used with a
592	  configuration to override the values from the configuration)
593	* added global control interface that can be optionally used for adding
594	  and removing network interfaces dynamically (-g command line argument
595	  for both wpa_supplicant and wpa_cli) without having to restart
596	  wpa_supplicant process
597	* wpa_gui:
598	  - try to save configuration whenever something is modified
599	  - added WEP key configuration
600	  - added possibility to edit the current network configuration
601	* driver_ndis: fixed driver polling not to increase frequency on each
602	  received EAPOL frame due to incorrectly cancelled timeout
603	* added simple configuration file examples (in examples subdirectory)
604	* fixed driver_wext.c to filter wireless events based on ifindex to
605	  avoid interfaces receiving events from other interfaces
606	* delay sending initial EAPOL-Start couple of seconds to speed up
607	  authentication for the most common case of Authenticator starting
608	  EAP authentication immediately after association
609
6102005-09-25 - v0.4.5
611	* added a workaround for clearing keys with ndiswrapper to allow
612	  roaming from WPA enabled AP to plaintext one
613	* added docbook documentation (doc/docbook) that can be used to
614	  generate, e.g., man pages
615	* l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
616	  PF_PACKET in order to prepare for network devices that do not use
617	  Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
618	* use receipt of EAPOL-Key frame as a lower layer success indication
619	  for EAP state machine to allow recovery from dropped EAP-Success
620	  frame
621	* cleaned up internal EAPOL frame processing by not including link
622	  layer (Ethernet) header during WPA and EAPOL/EAP processing; this
623	  header is added only when transmitted the frame; this makes it easier
624	  to use wpa_supplicant on link layers that use different header than
625	  Ethernet
626	* updated EAP-PSK to use draft 9 by default since this can now be
627	  tested with hostapd; removed support for draft 3, including
628	  server_nai configuration option from network blocks
629	* driver_wired: add PAE address to the multicast address list in order
630	  to be able to receive EAPOL frames with drivers that do not include
631	  these multicast addresses by default
632	* driver_wext: add support for WE-19
633	* added support for multiple configuration backends (CONFIG_BACKEND
634	  option); currently, only 'file' is supported (i.e., the format used
635	  in wpa_supplicant.conf)
636	* added support for updating configuration ('wpa_cli save_config');
637	  this is disabled by default and can be enabled with global
638	  update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
639	  and wpa_gui to store the configuration changes in a permanent store
640	* added GET_NETWORK ctrl_iface command
641	  (e.g., 'wpa_cli get_network 0 ssid')
642
6432005-08-21 - v0.4.4
644	* replaced OpenSSL patch for EAP-FAST support
645	  (openssl-tls-extensions.patch) with a more generic and correct
646	  patch (the new patch is not compatible with the previous one, so the
647	  OpenSSL library will need to be patched with the new patch in order
648	  to be able to build wpa_supplicant with EAP-FAST support)
649	* added support for using Windows certificate store (through CryptoAPI)
650	  for client certificate and private key operations (EAP-TLS)
651	  (see wpa_supplicant.conf for more information on how to configure
652	  this with private_key)
653	* ported wpa_gui to Windows
654	* added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
655	  built with the open source version of the Qt4 for Windows
656	* allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
657	  with drivers that do not support WPA
658	* ndis_events: fixed Windows 2000 support
659	* added support for enabling/disabling networks from the list of all
660	  configured networks ('wpa_cli enable_network <network id>' and
661	  'wpa_cli disable_network <network id>')
662	* added support for adding and removing network from the current
663	  configuration ('wpa_cli add_network' and 'wpa_cli remove_network
664	  <network id>'); added networks are disabled by default and they can
665	  be enabled with enable_network command once the configuration is done
666	  for the new network; note: configuration file is not yet updated, so
667	  these new networks are lost when wpa_supplicant is restarted
668	* added support for setting network configuration parameters through
669	  the control interface, for example:
670	  wpa_cli set_network 0 ssid "\"my network\""
671	* fixed parsing of strings that include both " and # within double
672	  quoted area (e.g., "start"#end")
673	* added EAP workaround for PEAP session resumption: allow outer,
674	  i.e., not tunneled, EAP-Success to terminate session since; this can
675	  be disabled with eap_workaround=0
676	  (this was allowed for PEAPv1 before, but now it is also allowed for
677	  PEAPv0 since at least one RADIUS authentication server seems to be
678	  doing this for PEAPv0, too)
679	* wpa_gui: added preliminary support for adding new networks to the
680	  wpa_supplicant configuration (double click on the scan results to
681	  open network configuration)
682
6832005-06-26 - v0.4.3
684	* removed interface for external EAPOL/EAP supplicant (e.g.,
685	  Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
686	  anymore and is unlikely to be used by anyone
687	* driver_ndis: fixed WinPcap 3.0 support
688	* fixed build with CONFIG_DNET_PCAP=y on Linux
689	* l2_packet: moved different implementations into separate files
690	  (l2_packet_*.c)
691
6922005-06-12 - v0.4.2
693	* driver_ipw: updated driver structures to match with ipw2200-1.0.4
694	  (note: ipw2100-1.1.0 is likely to require an update to work with
695	  this)
696	* added support for using ap_scan=2 mode with multiple network blocks;
697	  wpa_supplicant will go through the networks one by one until the
698	  driver reports a successful association; this uses the same order for
699	  networks as scan_ssid=1 scans, i.e., the priority field is ignored
700	  and the network block order in the file is used instead
701	* fixed a potential issue in RSN pre-authentication ending up using
702	  freed memory if pre-authentication times out
703	* added support for matching alternative subject name extensions of the
704	  authentication server certificate; new configuration variables
705	  altsubject_match and altsubject_match2
706	* driver_ndis: added support for IEEE 802.1X authentication with wired
707	  NDIS drivers
708	* added support for querying private key password (EAP-TLS) through the
709	  control interface (wpa_cli/wpa_gui) if one is not included in the
710	  configuration file
711	* driver_broadcom: fixed couple of memory leaks in scan result
712	  processing
713	* EAP-PAX is now registered as EAP type 46
714	* fixed EAP-PAX MAC calculation
715	* fixed EAP-PAX CK and ICK key derivation
716	* added support for using password with EAP-PAX (as an alternative to
717	  entering key with eappsk); SHA-1 hash of the password will be used as
718	  the key in this case
719	* added support for arbitrary driver interface parameters through the
720	  configuration file with a new driver_param field; this adds a new
721	  driver_ops function set_param()
722	* added possibility to override l2_packet module with driver interface
723	  API (new send_eapol handler); this can be used to implement driver
724	  specific TX/RX functions for EAPOL frames
725	* fixed ctrl_interface_group processing for the case where gid is
726	  entered as a number, not group name
727	* driver_test: added support for testing hostapd with wpa_supplicant
728	  by using test driver interface without any kernel drivers or network
729	  cards
730
7312005-05-22 - v0.4.1
732	* driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
733	  packets to be encrypted; this was apparently broken by the changed
734	  ioctl order in v0.4.0
735	* driver_madwifi: added preliminary support for compiling against 'BSD'
736	  branch of madwifi CVS tree
737	* added support for EAP-MSCHAPv2 password retries within the same EAP
738	  authentication session
739	* added support for password changes with EAP-MSCHAPv2 (used when the
740	  password has expired)
741	* added support for reading additional certificates from PKCS#12 files
742	  and adding them to the certificate chain
743	* fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
744	  were used
745	* fixed a possible double free in EAP-TTLS fast-reauthentication when
746	  identity or password is entered through control interface
747	* display EAP Notification messages to user through control interface
748	  with "CTRL-EVENT-EAP-NOTIFICATION" prefix
749	* added GUI version of wpa_cli, wpa_gui; this is not build
750	  automatically with 'make'; use 'make wpa_gui' to build (this requires
751	  Qt development tools)
752	* added 'disconnect' command to control interface for setting
753	  wpa_supplicant in state where it will not associate before
754	  'reassociate' command has been used
755	* added support for selecting a network from the list of all configured
756	  networks ('wpa_cli select_network <network id>'; this disabled all
757	  other networks; to re-enable, 'wpa_cli select_network any')
758	* added support for getting scan results through control interface
759	* added EAP workaround for PEAPv1 session resumption: allow outer,
760	  i.e., not tunneled, EAP-Success to terminate session since; this can
761	  be disabled with eap_workaround=0
762
7632005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
764	* added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
765	  used to reduce the size of the wpa_supplicant considerably if
766	  debugging code is not needed
767	* fixed EAPOL-Key validation to drop packets with invalid Key Data
768	  Length; such frames could have crashed wpa_supplicant due to buffer
769	  overflow
770	* added support for wired authentication (IEEE 802.1X on wired
771	  Ethernet); driver interface 'wired'
772	* obsoleted set_wpa() handler in the driver interface API (it can be
773	  replaced by moving enable/disable functionality into init()/deinit())
774	  (calls to set_wpa() are still present for backwards compatibility,
775	  but they may be removed in the future)
776	* driver_madwifi: fixed association in plaintext mode
777	* modified the EAP workaround that accepts EAP-Success with incorrect
778	  Identifier to be even less strict about verification in order to
779	  interoperate with some authentication servers
780	* added support for sending TLS alerts
781	* added support for 'any' SSID wildcard; if ssid is not configured or
782	  is set to an empty string, any SSID will be accepted for non-WPA AP
783	* added support for asking PIN (for SIM) from frontends (e.g.,
784	  wpa_cli); if a PIN is needed, but not included in the configuration
785	  file, a control interface request is sent and EAP processing is
786	  delayed until the PIN is available
787	* added support for using external devices (e.g., a smartcard) for
788	  private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
789	  new wpa_supplicant.conf variables:
790	  - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
791	  - network: engine, engine_id, key_id
792	* added experimental support for EAP-PAX
793	* added monitor mode for wpa_cli (-a<path to a program to run>) that
794	  allows external commands (e.g., shell scripts) to be run based on
795	  wpa_supplicant events, e.g., when authentication has been completed
796	  and data connection is ready; other related wpa_cli arguments:
797	  -B (run in background), -P (write PID file); wpa_supplicant has a new
798	  command line argument (-W) that can be used to make it wait until a
799	  control interface command is received in order to avoid missing
800	  events
801	* added support for opportunistic WPA2 PMKSA key caching (disabled by
802	  default, can be enabled with proactive_key_caching=1)
803	* fixed RSN IE in 4-Way Handshake message 2/4 for the case where
804	  Authenticator rejects PMKSA caching attempt and the driver is not
805	  using assoc_info events
806	* added -P<pid file> argument for wpa_supplicant to write the current
807	  process id into a file
808
8092005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
810	* added new phase1 option parameter, include_tls_length=1, to force
811	  wpa_supplicant to add TLS Message Length field to all TLS messages
812	  even if the packet is not fragmented; this may be needed with some
813	  authentication servers
814	* fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
815	  using drivers that take care of AP selection (e.g., when using
816	  ap_scan=2)
817	* fixed reprocessing of pending request after ctrl_iface requests for
818	  identity/password/otp
819	* fixed ctrl_iface requests for identity/password/otp in Phase 2 of
820	  EAP-PEAP and EAP-TTLS
821	* all drivers using driver_wext: set interface up and select Managed
822	  mode when starting wpa_supplicant; set interface down when exiting
823	* renamed driver_ipw2100.c to driver_ipw.c since it now supports both
824	  ipw2100 and ipw2200; please note that this also changed the
825	  configuration variable in .config to CONFIG_DRIVER_IPW
826
8272005-01-24 - v0.3.6
828	* fixed a busy loop introduced in v0.3.5 for scan result processing
829	  when no matching AP is found
830
8312005-01-23 - v0.3.5
832	* added a workaround for an interoperability issue with a Cisco AP
833	  when using WPA2-PSK
834	* fixed non-WPA IEEE 802.1X to use the same authentication timeout as
835	  WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
836	  retransmission of dropped frames)
837	* fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
838	  (e.g., segfault when processing EAPOL-Key frames)
839	* fixed EAP workaround and fast reauthentication configuration for
840	  RSN pre-authentication; previously these were disabled and
841	  pre-authentication would fail if the used authentication server
842	  requires EAP workarounds
843	* added support for blacklisting APs that fail or timeout
844	  authentication in ap_scan=1 mode so that all APs are tried in cases
845	  where the ones with strongest signal level are failing authentication
846	* fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
847	  authentication attempt
848	* allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
849	  in the previous authentication (previously, only Phase 1 success was
850	  verified)
851
8522005-01-09 - v0.3.4
853	* added preliminary support for IBSS (ad-hoc) mode configuration
854	  (mode=1 in network block); this included a new key_mgmt mode
855	  WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
856	  key management; see wpa_supplicant.conf for more details and an
857	  example on how to configure this (note: this is currently implemented
858	  only for driver_hostapd.c, but the changes should be trivial to add
859	  in associate() handler for other drivers, too (assuming the driver
860	  supports WPA-None)
861	* added preliminary port for native Windows (i.e., no cygwin) using
862	  mingw
863
8642005-01-02 - v0.3.3
865	* added optional support for GNU Readline and History Libraries for
866	  wpa_cli (CONFIG_READLINE)
867	* cleaned up EAP state machine <-> method interface and number of
868	  small problems with error case processing not terminating on
869	  EAP-Failure but waiting for timeout
870	* added couple of workarounds for interoperability issues with a
871	  Cisco AP when using WPA2
872	* added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
873	  Note: This requires a patch for openssl to add support for TLS
874	  extensions and number of workarounds for operations without
875	  certificates. Proof of concept type of experimental patch is
876	  included in openssl-tls-extensions.patch.
877
8782004-12-19 - v0.3.2
879	* fixed private key loading for cases where passphrase is not set
880	* fixed Windows/cygwin L2 packet handler freeing; previous version
881	  could cause a segfault when RSN pre-authentication was completed
882	* added support for PMKSA caching with drivers that generate RSN IEs
883	  (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
884	  but similar code can be easily added to driver_ndiswrapper.c once
885	  ndiswrapper gets full support for RSN PMKSA caching
886	* improved recovery from PMKID mismatches by requesting full EAP
887	  authentication in case of failed PMKSA caching attempt
888	* driver_ndis: added support for NDIS NdisMIncidateStatus() events
889	  (this requires that ndis_events is ran while wpa_supplicant is
890	  running)
891	* driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
892	* added support for driver interfaces to replace the interface name
893	  based on driver/OS specific mapping, e.g., in case of driver_ndis,
894	  this allows the beginning of the adapter description to be used as
895	  the interface name
896	* added support for CR+LF (Windows-style) line ends in configuration
897	  file
898	* driver_ndis: enable radio before starting scanning, disable radio
899	  when exiting
900	* modified association event handler to set portEnabled = FALSE before
901	  clearing port Valid in order to reset EAP state machine and avoid
902	  problems with new authentication getting ignored because of state
903	  machines ending up in AUTHENTICATED/SUCCESS state based on old
904	  information
905	* added support for driver events to add PMKID candidates in order to
906	  allow drivers to give priority to most likely roaming candidates
907	* driver_hostap: moved PrivacyInvoked configuration to associate()
908	  function so that this will not be set for plaintext connections
909	* added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
910	  interface can distinguish plaintext and IEEE 802.1X (no WPA)
911	  authentication
912	* fixed static WEP key configuration to use broadcast/default type for
913	  all keys (previously, the default TX key was configured as pairwise/
914	  unicast key)
915	* driver_ndis: added legacy WPA capability detection for non-WPA2
916	  drivers
917	* added support for setting static WEP keys for IEEE 802.1X without
918	  dynamic WEP keying (eapol_flags=0)
919
9202004-12-12 - v0.3.1
921	* added support for reading PKCS#12 (PFX) files (as a replacement for
922	  PEM/DER) to get certificate and private key (CONFIG_PKCS12)
923	* fixed compilation with CONFIG_PCSC=y
924	* added new ap_scan mode, ap_scan=2, for drivers that take care of
925	  association, but need to be configured with security policy and SSID,
926	  e.g., ndiswrapper and NDIS driver; this mode should allow such
927	  drivers to work with hidden SSIDs and optimized roaming; when
928	  ap_scan=2 is used, only the first network block in the configuration
929	  file is used and this configuration should have explicit security
930	  policy (i.e., only one option in the lists) for key_mgmt, pairwise,
931	  group, proto variables
932	* added experimental port of wpa_supplicant for Windows
933	  - driver_ndis.c driver interface (NDIS OIDs)
934	  - currently, this requires cygwin and WinPcap
935	  - small utility, win_if_list, can be used to get interface name
936	* control interface can now be removed at build time; add
937	  CONFIG_CTRL_IFACE=y to .config to maintain old functionality
938	* optional Xsupplicant interface can now be removed at build time;
939	  (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
940	* added auth_alg to driver interface associate() parameters to make it
941	  easier for drivers to configure authentication algorithm as part of
942	  the association
943
9442004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
945	* driver_broadcom: added new driver interface for Broadcom wl.o driver
946	  (a generic driver for Broadcom IEEE 802.11a/g cards)
947	* wpa_cli: fixed parsing of -p <path> command line argument
948	* PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
949	  ACK, not tunneled EAP-Success (of which only the first byte was
950	  actually send due to a bug in previous code); this seems to
951	  interoperate with most RADIUS servers that implements PEAPv1
952	* PEAPv1: added support for terminating PEAP authentication on tunneled
953	  EAP-Success message; this can be configured by adding
954	  peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
955	  (some RADIUS servers require this whereas others require a tunneled
956	  reply
957	* PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
958	  the old label for key derivation; previously, the default was 1,
959	  but it looks like most existing PEAPv1 implementations use the old
960	  label which is thus more suitable default option
961	* added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
962	* fixed parsing of wep_tx_keyidx
963	* added support for configuring list of allowed Phase 2 EAP types
964	  (for both EAP-PEAP and EAP-TTLS) instead of only one type
965	* added support for configuring IEEE 802.11 authentication algorithm
966	  (auth_alg; mainly for using Shared Key authentication with static
967	  WEP keys)
968	* added support for EAP-AKA (with UMTS SIM)
969	* fixed couple of errors in PCSC handling that could have caused
970	  random-looking errors for EAP-SIM
971	* added support for EAP-SIM pseudonyms and fast re-authentication
972	* added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
973	  session resumption)
974	* added support for EAP-SIM with two challanges
975	  (phase1="sim_min_num_chal=3" can be used to require three challenges)
976	* added support for configuring DH/DSA parameters for an ephemeral DH
977	  key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
978	  dh_file and dh_file2 (phase 2); this adds support for using DSA keys
979	  and optional DH key exchange to achieve forward secracy with RSA keys
980	* added support for matching subject of the authentication server
981	  certificate with a substring when using EAP-TLS/PEAP/TTLS; new
982	  configuration variables subject_match and subject_match2
983	* changed SSID configuration in driver_wext.c (used by many driver
984	  interfaces) to use ssid_len+1 as the length for SSID since some Linux
985	  drivers expect this
986	* fixed couple of unaligned reads in scan result parsing to fix WPA
987	  connection on some platforms (e.g., ARM)
988	* added driver interface for Intel ipw2100 driver
989	* added support for LEAP with WPA
990	* added support for larger scan results report (old limit was 4 kB of
991	  data, i.e., about 35 or so APs) when using Linux wireless extensions
992	  v17 or newer
993	* fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
994	  only if there is a PMKSA cache entry for the current AP
995	* fixed error handling for case where reading of scan results fails:
996	  must schedule a new scan or wpa_supplicant will remain waiting
997	  forever
998	* changed debug output to remove shared password/key material by
999	  default; all key information can be included with -K command line
1000	  argument to match the previous behavior
1001	* added support for timestamping debug log messages (disabled by
1002	  default, can be enabled with -t command line argument)
1003	* set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
1004	  if keys are not configured to be used; this fixes IEEE 802.1X mode
1005	  with drivers that use this information to configure whether Privacy
1006	  bit can be in Beacon frames (e.g., ndiswrapper)
1007	* avoid clearing driver keys if no keys have been configured since last
1008	  key clear request; this seems to improve reliability of group key
1009	  handshake for ndiswrapper & NDIS driver which seems to be suffering
1010	  of some kind of timing issue when the keys are cleared again after
1011	  association
1012	* changed driver interface API:
1013	  - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
1014	    version is being used (now, this is set to 2; previously, it was
1015	    not defined)
1016	  - pass pointer to private data structure to all calls
1017	  - the new API is not backwards compatible; all in-tree driver
1018	    interfaces has been converted to the new API
1019	* added support for controlling multiple interfaces (radios) per
1020	  wpa_supplicant process; each interface needs to be listed on the
1021	  command line (-c, -i, -D arguments) with -N as a separator
1022	  (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
1023	* added a workaround for EAP servers that incorrectly use same Id for
1024	  sequential EAP packets
1025	* changed libpcap/libdnet configuration to use .config variable,
1026	  CONFIG_DNET_PCAP, instead of requiring Makefile modification
1027	* improved downgrade attack detection in IE verification of msg 3/4:
1028	  verify both WPA and RSN IEs, if present, not only the selected one;
1029	  reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
1030	  Probe Response frame, and RSN is enabled in wpa_supplicant
1031	  configuration
1032	* fixed WPA msg 3/4 processing to allow Key Data field contain other
1033	  IEs than just one WPA IE
1034	* added support for FreeBSD and driver interface for the BSD net80211
1035	  layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
1036	  required kernel mods have not yet been committed
1037	* made EAP workarounds configurable; enabled by default, can be
1038	  disabled with network block option eap_workaround=0
1039
10402004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
1041	* resolved couple of interoperability issues with EAP-PEAPv1 and
1042	  Phase 2 (inner EAP) fragment reassembly
1043	* driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
1044	  AP is using non-zero key index for the unicast key and key index zero
1045	  for the broadcast key
1046	* driver_hostap: fixed IEEE 802.1X WEP key updates and
1047	  re-authentication by allowing unencrypted EAPOL frames when not using
1048	  WPA
1049	* added a new driver interface, 'wext', which uses only standard,
1050	  driver independent functionality in Linux wireless extensions;
1051	  currently, this can be used only for non-WPA IEEE 802.1X mode, but
1052	  eventually, this is to be extended to support full WPA/WPA2 once
1053	  Linux wireless extensions get support for this
1054	* added support for mode in which the driver is responsible for AP
1055	  scanning and selection; this is disabled by default and can be
1056	  enabled with global ap_scan=0 variable in wpa_supplicant.conf;
1057	  this mode can be used, e.g., with generic 'wext' driver interface to
1058	  use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
1059	  supporting wireless extensions.
1060	* driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
1061	  operation with an AP that does not include SSID in the Beacon frames)
1062	* added support for new EAP authentication methods:
1063	  EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
1064	* added support for asking one-time-passwords from frontends (e.g.,
1065	  wpa_cli); this 'otp' command works otherwise like 'password' command,
1066	  but the password is used only once and the frontend will be asked for
1067	  a new password whenever a request from authenticator requires a
1068	  password; this can be used with both EAP-OTP and EAP-GTC
1069	* changed wpa_cli to automatically re-establish connection so that it
1070	  does not need to be re-started when wpa_supplicant is terminated and
1071	  started again
1072	* improved user data (identity/password/otp) requests through
1073	  frontends: process pending EAPOL packets after getting new
1074	  information so that full authentication does not need to be
1075	  restarted; in addition, send pending requests again whenever a new
1076	  frontend is attached
1077	* changed control frontends to use a new directory for socket files to
1078	  make it easier for wpa_cli to automatically select between interfaces
1079	  and to provide access control for the control interface;
1080	  wpa_supplicant.conf: ctrl_interface is now a path
1081	  (/var/run/wpa_supplicant is the recommended path) and
1082	  ctrl_interface_group can be used to select which group gets access to
1083	  the control interface;
1084	  wpa_cli: by default, try to connect to the first interface available
1085	  in /var/run/wpa_supplicant; this path can be overriden with -p option
1086	  and an interface can be selected with -i option (i.e., in most common
1087	  cases, wpa_cli does not need to get any arguments)
1088	* added support for LEAP
1089	* added driver interface for Linux ndiswrapper
1090	* added priority option for network blocks in the configuration file;
1091	  this allows networks to be grouped based on priority (the scan
1092	  results are searched for matches with network blocks in this order)
1093
10942004-06-20 - v0.2.3
1095	* sort scan results to improve AP selection
1096	* fixed control interface socket removal for some error cases
1097	* improved scan requesting and authentication timeout
1098	* small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
1099	  TLS processing
1100	* PEAP version can now be forced with phase1="peapver=<ver>"
1101	  (mostly for testing; by default, the highest version supported by
1102	  both the Supplicant and Authentication Server is selected
1103	  automatically)
1104	* added support for madwifi driver (Atheros ar521x)
1105	* added a workaround for cases where AP sets Install Tx/Rx bit for
1106	  WPA Group Key messages when pairwise keys are used (without this,
1107	  the Group Key would be used for Tx and the AP would drop frames
1108	  from the station)
1109	* added GSM SIM/USIM interface for GSM authentication algorithm for
1110	  EAP-SIM; this requires pcsc-lite
1111	* added support for ATMEL AT76C5XXx driver
1112	* fixed IEEE 802.1X WEP key derivation in the case where Authenticator
1113	  does not include key data in the EAPOL-Key frame (i.e., part of
1114	  EAP keying material is used as data encryption key)
1115	* added support for using plaintext and static WEP networks
1116	  (key_mgmt=NONE)
1117
11182004-05-31 - v0.2.2
1119	* added support for new EAP authentication methods:
1120	  EAP-TTLS/EAP-MD5-Challenge
1121	  EAP-TTLS/EAP-GTC
1122	  EAP-TTLS/EAP-MSCHAPv2
1123	  EAP-TTLS/EAP-TLS
1124	  EAP-TTLS/MSCHAPv2
1125	  EAP-TTLS/MSCHAP
1126	  EAP-TTLS/PAP
1127	  EAP-TTLS/CHAP
1128	  EAP-PEAP/TLS
1129	  EAP-PEAP/GTC
1130	  EAP-PEAP/MD5-Challenge
1131	  EAP-GTC
1132	  EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
1133	* added support for anonymous identity (to be used when identity is
1134	  sent in plaintext; real identity will be used within TLS protected
1135	  tunnel (e.g., with EAP-TTLS)
1136	* added event messages from wpa_supplicant to frontends, e.g., wpa_cli
1137	* added support for requesting identity and password information using
1138	  control interface; in other words, the password for EAP-PEAP or
1139	  EAP-TTLS does not need to be included in the configuration file since
1140	  a frontand (e.g., wpa_cli) can ask it from the user
1141	* improved RSN pre-authentication to use a candidate list and process
1142	  all candidates from each scan; not only one per scan
1143	* fixed RSN IE and WPA IE capabilities field parsing
1144	* ignore Tx bit in GTK IE when Pairwise keys are used
1145	* avoid making new scan requests during IEEE 802.1X negotiation
1146	* use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
1147	  with TLS support (this replaces the included implementation with
1148	  library code to save about 8 kB since the library code is needed
1149	  anyway for TLS)
1150	* fixed WPA-PSK only mode when compiled without IEEE 802.1X support
1151	  (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
1152
11532004-05-06 - v0.2.1
1154	* added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
1155	  Supplicant
1156	  - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
1157	  - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
1158	  - EAP-MD5 (cannot be used with WPA-RADIUS)
1159	    [draft-ietf-eap-rfc2284bis-09.txt]
1160	  - EAP-TLS [RFC 2716]
1161	  - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
1162	  - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
1163	    [draft-kamath-pppext-eap-mschapv2-00.txt]
1164	    (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
1165	    default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
1166	  - new configuration file options: eap, identity, password, ca_cert,
1167	    client_cert, privatekey, private_key_passwd
1168	  - Xsupplicant is not required anymore, but it can be used by
1169	    disabling the internal IEEE 802.1X Supplicant with -e command line
1170	    option
1171	  - this code is not included in the default build; Makefile need to
1172	    be edited for this (uncomment lines for selected functionality)
1173	  - EAP-TLS and EAP-PEAP require openssl libraries
1174	* use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
1175	* added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
1176	  (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
1177	   EAPOL-Key frames instead of WPA key handshakes)
1178	* added support for IEEE 802.11i/RSN (WPA2)
1179	  - improved PTK Key Handshake
1180	  - PMKSA caching, pre-authentication
