1ChangeLog for hostapd
2
32009-02-15 - v0.6.8
4	* increased hostapd_cli ping interval to 5 seconds and made this
5	  configurable with a new command line options (-G<seconds>)
6	* driver_nl80211: use Linux socket filter to improve performance
7	* added support for external Registrars with WPS (UPnP transport)
8
92009-01-06 - v0.6.7
10	* added support for Wi-Fi Protected Setup (WPS)
11	  (hostapd can now be configured to act as an integrated WPS Registrar
12	  and provision credentials for WPS Enrollees using PIN and PBC
13	  methods; external wireless Registrar can configure the AP, but
14	  external WLAN Manager Registrars are not supported); WPS support can
15	  be enabled by adding CONFIG_WPS=y into .config and setting the
16	  runtime configuration variables in hostapd.conf (see WPS section in
17	  the example configuration file); new hostapd_cli commands wps_pin and
18	  wps_pbc are used to configure WPS negotiation; see README-WPS for
19	  more details
20	* added IEEE 802.11n HT capability configuration (ht_capab)
21	* added support for generating Country IE based on nl80211 regulatory
22	  information (added if ieee80211d=1 in configuration)
23	* fixed WEP authentication (both Open System and Shared Key) with
24	  mac80211
25	* added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
26	* added support for using driver_test over UDP socket
27	* changed EAP-GPSK to use the IANA assigned EAP method type 51
28	* updated management frame protection to use IEEE 802.11w/D7.0
29	* fixed retransmission of EAP requests if no response is received
30
312008-11-23 - v0.6.6
32	* added a new configuration option, wpa_ptk_rekey, that can be used to
33	  enforce frequent PTK rekeying, e.g., to mitigate some attacks against
34	  TKIP deficiencies
35	* updated OpenSSL code for EAP-FAST to use an updated version of the
36	  session ticket overriding API that was included into the upstream
37	  OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
38	  needed with that version anymore)
39	* changed channel flags configuration to read the information from
40	  the driver (e.g., via driver_nl80211 when using mac80211) instead of
41	  using hostapd as the source of the regulatory information (i.e.,
42	  information from CRDA is now used with mac80211); this allows 5 GHz
43	  channels to be used with hostapd (if allowed in the current
44	  regulatory domain)
45	* fixed EAP-TLS message processing for the last TLS message if it is
46	  large enough to require fragmentation (e.g., if a large Session
47	  Ticket data is included)
48	* fixed listen interval configuration for nl80211 drivers
49
502008-11-01 - v0.6.5
51	* added support for SHA-256 as X.509 certificate digest when using the
52	  internal X.509/TLSv1 implementation
53	* fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer
54	  identity lengths)
55	* fixed internal TLSv1 implementation for abbreviated handshake (used
56	  by EAP-FAST server)
57	* added support for setting VLAN ID for STAs based on local MAC ACL
58	  (accept_mac_file) as an alternative for RADIUS server-based
59	  configuration
60	* updated management frame protection to use IEEE 802.11w/D6.0
61	  (adds a new association ping to protect against unauthenticated
62	  authenticate or (re)associate request frames dropping association)
63	* added support for using SHA256-based stronger key derivation for WPA2
64	  (IEEE 802.11w)
65	* added new "driver wrapper" for RADIUS-only configuration
66	  (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config)
67	* fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2)
68	  is enabled in configuration
69	* changed EAP-FAST configuration to use separate fields for A-ID and
70	  A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed
71	  16-octet len binary value for better interoperability with some peer
72	  implementations; eap_fast_a_id is now configured as a hex string
73	* driver_nl80211: Updated to match the current Linux mac80211 AP mode
74	  configuration (wireless-testing.git and Linux kernel releases
75	  starting from 2.6.29)
76
772008-08-10 - v0.6.4
78	* added peer identity into EAP-FAST PAC-Opaque and skip Phase 2
79	  Identity Request if identity is already known
80	* added support for EAP Sequences in EAP-FAST Phase 2
81	* added support for EAP-TNC (Trusted Network Connect)
82	  (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST
83	  changes needed to run two methods in sequence (IF-T) and the IF-IMV
84	  and IF-TNCCS interfaces from TNCS)
85	* added support for optional cryptobinding with PEAPv0
86	* added fragmentation support for EAP-TNC
87	* added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled)
88	  data
89	* added support for opportunistic key caching (OKC)
90
912008-02-22 - v0.6.3
92	* fixed Reassociation Response callback processing when using internal
93	  MLME (driver_{hostap,nl80211,test}.c)
94	* updated FT support to use the latest draft, IEEE 802.11r/D9.0
95	* copy optional Proxy-State attributes into RADIUS response when acting
96	  as a RADIUS authentication server
97	* fixed EAPOL state machine to handle a case in which no response is
98	  received from the RADIUS authentication server; previous version
99	  could have triggered a crash in some cases after a timeout
100	* fixed EAP-SIM/AKA realm processing to allow decorated usernames to
101	  be used
102	* added a workaround for EAP-SIM/AKA peers that include incorrect null
103	  termination in the username
104	* fixed EAP-SIM/AKA protected result indication to include AT_COUNTER
105	  attribute in notification messages only when using fast
106	  reauthentication
107	* fixed EAP-SIM Start response processing for fast reauthentication
108	  case
109	* added support for pending EAP processing in EAP-{PEAP,TTLS,FAST}
110	  phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method
111
1122008-01-01 - v0.6.2
113	* fixed EAP-SIM and EAP-AKA message parser to validate attribute
114	  lengths properly to avoid potential crash caused by invalid messages
115	* added data structure for storing allocated buffers (struct wpabuf);
116	  this does not affect hostapd usage, but many of the APIs changed
117	  and various interfaces (e.g., EAP) is not compatible with old
118	  versions
119	* added support for protecting EAP-AKA/Identity messages with
120	  AT_CHECKCODE (optional feature in RFC 4187)
121	* added support for protected result indication with AT_RESULT_IND for
122	  EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1)
123	* added support for configuring EAP-TTLS phase 2 non-EAP methods in
124	  EAP server configuration; previously all four were enabled for every
125	  phase 2 user, now all four are disabled by default and need to be
126	  enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP,
127	  TTLS-MSCHAPV2
128	* removed old debug printing mechanism and the related 'debug'
129	  parameter in the configuration file; debug verbosity is now set with
130	  -d (or -dd) command line arguments
131	* added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
132	  only shared key/password authentication is supported in this version
133
1342007-11-24 - v0.6.1
135	* added experimental, integrated TLSv1 server implementation with the
136	  needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
137	  setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
138	  .config); this can be useful, e.g., if the target system does not
139	  have a suitable TLS library and a minimal code size is required
140	* added support for EAP-FAST server method to the integrated EAP
141	  server
142	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
143	  draft (draft-ietf-emu-eap-gpsk-07.txt)
144	* added a new configuration parameter, rsn_pairwise, to allow different
145	  pairwise cipher suites to be enabled for WPA and RSN/WPA2
146	  (note: if wpa_pairwise differs from rsn_pairwise, the driver will
147	  either need to support this or will have to use the WPA/RSN IEs from
148	  hostapd; currently, the included madwifi and bsd driver interfaces do
149	  not have support for this)
150	* updated FT support to use the latest draft, IEEE 802.11r/D8.0
151
1522007-05-28 - v0.6.0
153	* added experimental IEEE 802.11r/D6.0 support
154	* updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
155	* updated EAP-PSK to use the IANA-allocated EAP type 47
156	* fixed EAP-PSK bit ordering of the Flags field
157	* fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
158	  by reading wpa_psk_file [Bug 181]
159	* fixed EAP-TTLS AVP parser processing for too short AVP lengths
160	* fixed IPv6 connection to RADIUS accounting server
161	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
162	  draft (draft-ietf-emu-eap-gpsk-04.txt)
163	* hlr_auc_gw: read GSM triplet file into memory and rotate through the
164	  entries instead of only using the same three triplets every time
165	  (this does not work properly with tests using multiple clients, but
166	  provides bit better triplet data for testing a single client; anyway,
167	  if a better quality triplets are needed, GSM-Milenage should be used
168	  instead of hardcoded triplet file)
169	* fixed EAP-MSCHAPv2 server to use a space between S and M parameters
170	  in Success Request [Bug 203]
171	* added support for sending EAP-AKA Notifications in error cases
172	* updated to use IEEE 802.11w/D2.0 for management frame protection
173	  (still experimental)
174	* RADIUS server: added support for processing duplicate messages
175	  (retransmissions from RADIUS client) by replying with the previous
176	  reply
177
1782006-11-24 - v0.5.6
179	* added support for configuring and controlling multiple BSSes per
180	  radio interface (bss=<ifname> in hostapd.conf); this is only
181	  available with Devicescape and test driver interfaces
182	* fixed PMKSA cache update in the end of successful RSN
183	  pre-authentication
184	* added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
185	  for each STA based on RADIUS Access-Accept attributes); this requires
186	  VLAN support from the kernel driver/802.11 stack and this is
187	  currently only available with Devicescape and test driver interfaces
188	* driver_madwifi: fixed configuration of unencrypted modes (plaintext
189	  and IEEE 802.1X without WEP)
190	* removed STAKey handshake since PeerKey handshake has replaced it in
191	  IEEE 802.11ma and there are no known deployments of STAKey
192	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
193	  draft (draft-ietf-emu-eap-gpsk-01.txt)
194	* added preliminary implementation of IEEE 802.11w/D1.0 (management
195	  frame protection)
196	  (Note: this requires driver support to work properly.)
197	  (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
198	* hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
199	* hlr_auc_gw: added support for reading per-IMSI Milenage keys and
200	  parameters from a text file to make it possible to implement proper
201	  GSM/UMTS authentication server for multiple SIM/USIM cards using
202	  EAP-SIM/EAP-AKA
203	* fixed session timeout processing with drivers that do not use
204	  ieee802_11.c (e.g., madwifi)
205
2062006-08-27 - v0.5.5
207	* added 'hostapd_cli new_sta <addr>' command for adding a new STA into
208	  hostapd (e.g., to initialize wired network authentication based on an
209	  external signal)
210	* fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
211	  using WPA2 even if PMKSA caching is not used
212	* added -P<pid file> argument for hostapd to write the current process
213	  id into a file
214	* added support for RADIUS Authentication Server MIB (RFC 2619)
215
2162006-06-20 - v0.5.4
217	* fixed nt_password_hash build [Bug 144]
218	* added PeerKey handshake implementation for IEEE 802.11e
219	  direct link setup (DLS) to replace STAKey handshake
220	* added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
221	  draft-clancy-emu-eap-shared-secret-00.txt)
222	* fixed a segmentation fault when RSN pre-authentication was completed
223	  successfully [Bug 152]
224
2252006-04-27 - v0.5.3
226	* do not build nt_password_hash and hlr_auc_gw by default to avoid
227	  requiring a TLS library for a successful build; these programs can be
228	  build with 'make nt_password_hash' and 'make hlr_auc_gw'
229	* added a new configuration option, eapol_version, that can be used to
230	  set EAPOL version to 1 (default is 2) to work around broken client
231	  implementations that drop EAPOL frames which use version number 2
232	  [Bug 89]
233	* added support for EAP-SAKE (no EAP method number allocated yet, so
234	  this is using the same experimental type 255 as EAP-PSK)
235	* fixed EAP-MSCHAPv2 message length validation
236
2372006-03-19 - v0.5.2
238	* fixed stdarg use in hostapd_logger(): if both stdout and syslog
239	  logging was enabled, hostapd could trigger a segmentation fault in
240	  vsyslog on some CPU -- C library combinations
241	* moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
242	  program to make it easier to use for implementing real SS7 gateway;
243	  eap_sim_db is not anymore used as a file name for GSM authentication
244	  triplets; instead, it is path to UNIX domain socket that will be used
245	  to communicate with the external gateway program (e.g., hlr_auc_gw)
246	* added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
247	  local information (GSM authentication triplets from a text file and
248	  hardcoded AKA authentication data); this can be used to test EAP-SIM
249	  and EAP-AKA
250	* added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
251	  to make it possible to test EAP-AKA with real USIM cards (this is
252	  disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
253	  to enable this)
254	* driver_madwifi: added support for getting station RSN IE from
255	  madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
256	  broken with earlier change (r1357) in the driver
257	* changed EAP method registration to use a dynamic list of methods
258	  instead of a static list generated at build time
259	* fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
260	  [Bug 125]
261	* added ap_max_inactivity configuration parameter
262
2632006-01-29 - v0.5.1
264	* driver_test: added better support for multiple APs and STAs by using
265	  a directory with sockets that include MAC address for each device in
266	  the name (test_socket=DIR:/tmp/test)
267	* added support for EAP expanded type (vendor specific EAP methods)
268
2692005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
270	* added experimental STAKey handshake implementation for IEEE 802.11e
271	  direct link setup (DLS); note: this is disabled by default in both
272	  build and runtime configuration (can be enabled with CONFIG_STAKEY=y
273	  and stakey=1)
274	* added support for EAP methods to use callbacks to external programs
275	  by buffering a pending request and processing it after the EAP method
276	  is ready to continue
277	* improved EAP-SIM database interface to allow external request to GSM
278	  HLR/AuC without blocking hostapd process
279	* added support for using EAP-SIM pseudonyms and fast re-authentication
280	* added support for EAP-AKA in the integrated EAP authenticator
281	* added support for matching EAP identity prefixes (e.g., "1"*) in EAP
282	  user database to allow EAP-SIM/AKA selection without extra roundtrip
283	  for EAP-Nak negotiation
284	* added support for storing EAP user password as NtPasswordHash instead
285	  of plaintext password when using MSCHAP or MSCHAPv2 for
286	  authentication (hash:<16-octet hex value>); added nt_password_hash
287	  tool for hashing password to generate NtPasswordHash
288
2892005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
290	* driver_wired: fixed EAPOL sending to optionally use PAE group address
291	  as the destination instead of supplicant MAC address; this is
292	  disabled by default, but should be enabled with use_pae_group_addr=1
293	  in configuration file if the wired interface is used by only one
294	  device at the time (common switch configuration)
295	* driver_madwifi: configure driver to use TKIP countermeasures in order
296	  to get correct behavior (IEEE 802.11 association failing; previously,
297	  association succeeded, but hostpad forced disassociation immediately)
298	* driver_madwifi: added support for madwifi-ng
299
3002005-10-27 - v0.4.6
301	* added support for replacing user identity from EAP with RADIUS
302	  User-Name attribute from Access-Accept message, if that is included,
303	  for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
304	  tunneled identity into accounting messages when the RADIUS server
305	  does not support better way of doing this with Class attribute)
306	* driver_madwifi: fixed EAPOL packet receive for configuration where
307	  ath# is part of a bridge interface
308	* added a configuration file and log analyzer script for logwatch
309	* fixed EAPOL state machine step function to process all state
310	  transitions before processing new events; this resolves a race
311	  condition in which EAPOL-Start message could trigger hostapd to send
312	  two EAP-Response/Identity frames to the authentication server
313
3142005-09-25 - v0.4.5
315	* added client CA list to the TLS certificate request in order to make
316	  it easier for the client to select which certificate to use
317	* added experimental support for EAP-PSK
318	* added support for WE-19 (hostap, madwifi)
319
3202005-08-21 - v0.4.4
321	* fixed build without CONFIG_RSN_PREAUTH
322	* fixed FreeBSD build
323
3242005-06-26 - v0.4.3
325	* fixed PMKSA caching to copy User-Name and Class attributes so that
326	  RADIUS accounting gets correct information
327	* start RADIUS accounting only after successful completion of WPA
328	  4-Way Handshake if WPA-PSK is used
329	* fixed PMKSA caching for the case where STA (re)associates without
330	  first disassociating
331
3322005-06-12 - v0.4.2
333	* EAP-PAX is now registered as EAP type 46
334	* fixed EAP-PAX MAC calculation
335	* fixed EAP-PAX CK and ICK key derivation
336	* renamed eap_authenticator configuration variable to eap_server to
337	  better match with RFC 3748 (EAP) terminology
338	* driver_test: added support for testing hostapd with wpa_supplicant
339	  by using test driver interface without any kernel drivers or network
340	  cards
341
3422005-05-22 - v0.4.1
343	* fixed RADIUS server initialization when only auth or acct server
344	  is configured and the other one is left empty
345	* driver_madwifi: added support for RADIUS accounting
346	* driver_madwifi: added preliminary support for compiling against 'BSD'
347	  branch of madwifi CVS tree
348	* driver_madwifi: fixed pairwise key removal to allow WPA reauth
349	  without disassociation
350	* added support for reading additional certificates from PKCS#12 files
351	  and adding them to the certificate chain
352	* fixed RADIUS Class attribute processing to only use Access-Accept
353	  packets to update Class; previously, other RADIUS authentication
354	  packets could have cleared Class attribute
355	* added support for more than one Class attribute in RADIUS packets
356	* added support for verifying certificate revocation list (CRL) when
357	  using integrated EAP authenticator for EAP-TLS; new hostapd.conf
358	  options 'check_crl'; CRL must be included in the ca_cert file for now
359
3602005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
361	* added support for including network information into
362	  EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
363	  (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
364	* fixed a bug which caused some RSN pre-authentication cases to use
365	  freed memory and potentially crash hostapd
366	* fixed private key loading for cases where passphrase is not set
367	* added support for sending TLS alerts and aborting authentication
368	  when receiving a TLS alert
369	* fixed WPA2 to add PMKSA cache entry when using integrated EAP
370	  authenticator
371	* fixed PMKSA caching (EAP authentication was not skipped correctly
372	  with the new state machine changes from IEEE 802.1X draft)
373	* added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
374	  and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
375	  to be added to .config to include IPv6 support); for RADIUS server,
376	  radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
377	  in RADIUS clients file can then use IPv6 format
378	* added experimental support for EAP-PAX
379	* replaced hostapd control interface library (hostapd_ctrl.[ch]) with
380	  the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
381
3822005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
383
3842005-01-23 - v0.3.5
385	* added support for configuring a forced PEAP version based on the
386	  Phase 1 identity
387	* fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
388	  to terminate authentication
389	* fixed EAP identifier duplicate processing with the new IEEE 802.1X
390	  draft
391	* clear accounting data in the driver when starting a new accounting
392	  session
393	* driver_madwifi: filter wireless events based on ifindex to allow more
394	  than one network interface to be used
395	* fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
396	  setting if the packet does not pass MIC verification (e.g., due to
397	  incorrect PSK); previously, message 1/4 was not tried again if an
398	  invalid message 2/4 was received
399	* fixed reconfiguration of RADIUS client retransmission timer when
400	  adding a new message to the pending list; previously, timer was not
401	  updated at this point and if there was a pending message with long
402	  time for the next retry, the new message needed to wait that long for
403	  its first retry, too
404
4052005-01-09 - v0.3.4
406	* added support for configuring multiple allowed EAP types for Phase 2
407	  authentication (EAP-PEAP, EAP-TTLS)
408	* fixed EAPOL-Start processing to trigger WPA reauthentication
409	  (previously, only EAPOL authentication was done)
410
4112005-01-02 - v0.3.3
412	* added support for EAP-PEAP in the integrated EAP authenticator
413	* added support for EAP-GTC in the integrated EAP authenticator
414	* added support for configuring list of EAP methods for Phase 1 so that
415	  the integrated EAP authenticator can, e.g., use the wildcard entry
416	  for EAP-TLS and EAP-PEAP
417	* added support for EAP-TTLS in the integrated EAP authenticator
418	* added support for EAP-SIM in the integrated EAP authenticator
419	* added support for using hostapd as a RADIUS authentication server
420	  with the integrated EAP authenticator taking care of EAP
421	  authentication (new hostapd.conf options: radius_server_clients and
422	  radius_server_auth_port); this is not included in default build; use
423	  CONFIG_RADIUS_SERVER=y in .config to include
424
4252004-12-19 - v0.3.2
426	* removed 'daemonize' configuration file option since it has not really
427	  been used at all for more than year
428	* driver_madwifi: fixed group key setup and added get_ssid method
429	* added support for EAP-MSCHAPv2 in the integrated EAP authenticator
430
4312004-12-12 - v0.3.1
432	* added support for integrated EAP-TLS authentication (new hostapd.conf
433	  variables: ca_cert, server_cert, private_key, private_key_passwd);
434	  this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
435	  external RADIUS server
436	* added support for reading PKCS#12 (PFX) files (as a replacement for
437	  PEM/DER) to get certificate and private key (CONFIG_PKCS12)
438
4392004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
440	* added support for Acct-{Input,Output}-Gigawords
441	* added support for Event-Timestamp (in RADIUS Accounting-Requests)
442	* added support for RADIUS Authentication Client MIB (RFC2618)
443	* added support for RADIUS Accounting Client MIB (RFC2620)
444	* made EAP re-authentication period configurable (eap_reauth_period)
445	* fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
446	* fixed EAPOL state machine to stop if STA is removed during
447	  eapol_sm_step(); this fixes at least one segfault triggering bug with
448	  IEEE 802.11i pre-authentication
449	* added support for multiple WPA pre-shared keys (e.g., one for each
450	  client MAC address or keys shared by a group of clients);
451	  new hostapd.conf field wpa_psk_file for setting path to a text file
452	  containing PSKs, see hostapd.wpa_psk for an example
453	* added support for multiple driver interfaces to allow hostapd to be
454	  used with other drivers
455	* added wired authenticator driver interface (driver=wired in
456	  hostapd.conf, see wired.conf for example configuration)
457	* added madwifi driver interface (driver=madwifi in hostapd.conf, see
458	  madwifi.conf for example configuration; Note: include files from
459	  madwifi project is needed for building and a configuration file,
460	  .config, needs to be created in hostapd directory with
461	  CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
462	  build)
463	* fixed an alignment issue that could cause SHA-1 to fail on some
464	  platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
465	  align variables)
466	* fixed RADIUS reconnection after an error in sending interim
467	  accounting packets
468	* added hostapd control interface for external programs and an example
469	  CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
470	* started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
471	  'hostapd_cli sta <addr>')
472	* finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
473	* added support for strict GTK rekeying (wpa_strict_rekey in
474	  hostapd.conf)
475	* updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
476	  (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
477	  IEEE 802.11F-2003)
478	* added Prism54 driver interface (driver=prism54 in hostapd.conf;
479	  note: .config needs to be created in hostapd directory with
480	  CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
481	  build)
482	* dual-licensed hostapd (GPLv2 and BSD licenses)
483	* fixed RADIUS accounting to generate a new session id for cases where
484	  a station reassociates without first being complete deauthenticated
485	* fixed STA disassociation handler to mark next timeout state to
486	  deauthenticate the station, i.e., skip long wait for inactivity poll
487	  and extra disassociation, if the STA disassociates without
488	  deauthenticating
489	* added integrated EAP authenticator that can be used instead of
490	  external RADIUS authentication server; currently, only EAP-MD5 is
491	  supported, so this cannot yet be used for key distribution; the EAP
492	  method interface is generic, though, so adding new EAP methods should
493	  be straightforward; new hostapd.conf variables: 'eap_authenticator'
494	  and 'eap_user_file'; this obsoletes "minimal authentication server"
495	  ('minimal_eap' in hostapd.conf) which is now removed
496	* added support for FreeBSD and driver interface for the BSD net80211
497	  layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
498	  .config); please note that some of the required kernel mods have not
499	  yet been committed
500
5012004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
502	* fixed some accounting cases where Accounting-Start was sent when
503	  IEEE 802.1X port was being deauthorized
504
5052004-06-20 - v0.2.3
506	* modified RADIUS client to re-connect the socket in case of certain
507	  error codes that are generated when a network interface state is
508	  changes (e.g., when IP address changes or the interface is set UP)
509	* fixed couple of cases where EAPOL state for a station was freed
510	  twice causing a segfault for hostapd
511	* fixed couple of bugs in processing WPA deauthentication (freed data
512	  was used)
513
5142004-05-31 - v0.2.2
515	* fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
516	* fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
517	  cases where STAs dropped multicast frames as replay attacks
518	* added support for copying RADIUS Attribute 'Class' from
519	  authentication messages into accounting messages
520	* send canned EAP failure if RADIUS server sends Access-Reject without
521	  EAP message (previously, Supplicant was not notified in this case)
522	* fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
523	  not start EAPOL state machines if the STA selected to use WPA-PSK)
524
5252004-05-06 - v0.2.1
526	* added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
527	  - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
528	    (i.e., IEEE 802.11i/D3.0)
529	  - supports WPA-only, RSN-only, and mixed WPA/RSN mode
530	  - both WPA-PSK and WPA-RADIUS/EAP are supported
531	  - PMKSA caching and pre-authentication
532	  - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
533	    wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
534	    rsn_preauth, rsn_preauth_interfaces
535	* fixed interim accounting to remove any pending accounting messages
536	  to the STA before sending a new one
537
5382004-02-15 - v0.2.0
539	* added support for Acct-Interim-Interval:
540	  - draft-ietf-radius-acct-interim-01.txt
541	  - use Acct-Interim-Interval attribute from Access-Accept if local
542	    'radius_acct_interim_interval' is not set
543	  - allow different update intervals for each STA
544	* fixed event loop to call signal handlers only after returning from
545	  the real signal handler
546	* reset sta->timeout_next after successful association to make sure
547	  that the previously registered inactivity timer will not remove the
548	  STA immediately (e.g., if STA deauthenticates and re-associates
549	  before the timer is triggered).
550	* added new hostapd.conf variable, nas_identifier, that can be used to
551	  add an optional RADIUS Attribute, NAS-Identifier, into authentication
552	  and accounting messages
553	* added support for Accounting-On and Accounting-Off messages
554	* fixed accounting session handling to send Accounting-Start only once
555	  per session and not to send Accounting-Stop if the session was not
556	  initialized properly
557	* fixed Accounting-Stop statistics in cases where the message was
558	  previously sent after the kernel entry for the STA (and/or IEEE
559	  802.1X data) was removed
560
