4 * added support for Wi-Fi Protected Setup (WPS)
5 (hostapd can now be configured to act as an integrated WPS Registrar
6 and provision credentials for WPS Enrollees using PIN and PBC
7 methods; external WPS Registrars are not supported); WPS support can
8 be enabled by adding CONFIG_WPS=y into .config and setting the
9 runtime configuration variables in hostapd.conf (see WPS section in
10 the example configuration file); new hostapd_cli commands wps_pin and
11 wps_pbc are used to configure WPS negotiation; see README-WPS for
13 * added IEEE 802.11n HT capability configuration (ht_capab)
14 * added support for generating Country IE based on nl80211 regulatory
15 information (added if ieee80211d=1 in configuration)
16 * fixed WEP authentication (both Open System and Shared Key) with
18 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
19 * added support for using driver_test over UDP socket
20 * changed EAP-GPSK to use the IANA assigned EAP method type 51
23 * added a new configuration option, wpa_ptk_rekey, that can be used to
24 enforce frequent PTK rekeying, e.g., to mitigate some attacks against
26 * updated OpenSSL code for EAP-FAST to use an updated version of the
27 session ticket overriding API that was included into the upstream
28 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
29 needed with that version anymore)
30 * changed channel flags configuration to read the information from
31 the driver (e.g., via driver_nl80211 when using mac80211) instead of
32 using hostapd as the source of the regulatory information (i.e.,
33 information from CRDA is now used with mac80211); this allows 5 GHz
34 channels to be used with hostapd (if allowed in the current
36 * fixed EAP-TLS message processing for the last TLS message if it is
37 large enough to require fragmentation (e.g., if a large Session
38 Ticket data is included)
39 * fixed listen interval configuration for nl80211 drivers
42 * added support for SHA-256 as X.509 certificate digest when using the
43 internal X.509/TLSv1 implementation
44 * fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer
46 * fixed internal TLSv1 implementation for abbreviated handshake (used
48 * added support for setting VLAN ID for STAs based on local MAC ACL
49 (accept_mac_file) as an alternative for RADIUS server-based
51 * updated management frame protection to use IEEE 802.11w/D6.0
52 (adds a new association ping to protect against unauthenticated
53 authenticate or (re)associate request frames dropping association)
54 * added support for using SHA256-based stronger key derivation for WPA2
56 * added new "driver wrapper" for RADIUS-only configuration
57 (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config)
58 * fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2)
59 is enabled in configuration
60 * changed EAP-FAST configuration to use separate fields for A-ID and
61 A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed
62 16-octet len binary value for better interoperability with some peer
63 implementations; eap_fast_a_id is now configured as a hex string
64 * driver_nl80211: Updated to match the current Linux mac80211 AP mode
65 configuration (wireless-testing.git and Linux kernel releases
69 * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2
70 Identity Request if identity is already known
71 * added support for EAP Sequences in EAP-FAST Phase 2
72 * added support for EAP-TNC (Trusted Network Connect)
73 (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST
74 changes needed to run two methods in sequence (IF-T) and the IF-IMV
75 and IF-TNCCS interfaces from TNCS)
76 * added support for optional cryptobinding with PEAPv0
77 * added fragmentation support for EAP-TNC
78 * added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled)
80 * added support for opportunistic key caching (OKC)
83 * fixed Reassociation Response callback processing when using internal
84 MLME (driver_{hostap,nl80211,test}.c)
85 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
86 * copy optional Proxy-State attributes into RADIUS response when acting
87 as a RADIUS authentication server
88 * fixed EAPOL state machine to handle a case in which no response is
89 received from the RADIUS authentication server; previous version
90 could have triggered a crash in some cases after a timeout
91 * fixed EAP-SIM/AKA realm processing to allow decorated usernames to
93 * added a workaround for EAP-SIM/AKA peers that include incorrect null
94 termination in the username
95 * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER
96 attribute in notification messages only when using fast
98 * fixed EAP-SIM Start response processing for fast reauthentication
100 * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST}
101 phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method
104 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
105 lengths properly to avoid potential crash caused by invalid messages
106 * added data structure for storing allocated buffers (struct wpabuf);
107 this does not affect hostapd usage, but many of the APIs changed
108 and various interfaces (e.g., EAP) is not compatible with old
110 * added support for protecting EAP-AKA/Identity messages with
111 AT_CHECKCODE (optional feature in RFC 4187)
112 * added support for protected result indication with AT_RESULT_IND for
113 EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1)
114 * added support for configuring EAP-TTLS phase 2 non-EAP methods in
115 EAP server configuration; previously all four were enabled for every
116 phase 2 user, now all four are disabled by default and need to be
117 enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP,
119 * removed old debug printing mechanism and the related 'debug'
120 parameter in the configuration file; debug verbosity is now set with
121 -d (or -dd) command line arguments
122 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
123 only shared key/password authentication is supported in this version
126 * added experimental, integrated TLSv1 server implementation with the
127 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
128 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
129 .config); this can be useful, e.g., if the target system does not
130 have a suitable TLS library and a minimal code size is required
131 * added support for EAP-FAST server method to the integrated EAP
133 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
134 draft (draft-ietf-emu-eap-gpsk-07.txt)
135 * added a new configuration parameter, rsn_pairwise, to allow different
136 pairwise cipher suites to be enabled for WPA and RSN/WPA2
137 (note: if wpa_pairwise differs from rsn_pairwise, the driver will
138 either need to support this or will have to use the WPA/RSN IEs from
139 hostapd; currently, the included madwifi and bsd driver interfaces do
140 not have support for this)
141 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
144 * added experimental IEEE 802.11r/D6.0 support
145 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
146 * updated EAP-PSK to use the IANA-allocated EAP type 47
147 * fixed EAP-PSK bit ordering of the Flags field
148 * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
149 by reading wpa_psk_file [Bug 181]
150 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
151 * fixed IPv6 connection to RADIUS accounting server
152 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
153 draft (draft-ietf-emu-eap-gpsk-04.txt)
154 * hlr_auc_gw: read GSM triplet file into memory and rotate through the
155 entries instead of only using the same three triplets every time
156 (this does not work properly with tests using multiple clients, but
157 provides bit better triplet data for testing a single client; anyway,
158 if a better quality triplets are needed, GSM-Milenage should be used
159 instead of hardcoded triplet file)
160 * fixed EAP-MSCHAPv2 server to use a space between S and M parameters
161 in Success Request [Bug 203]
162 * added support for sending EAP-AKA Notifications in error cases
163 * updated to use IEEE 802.11w/D2.0 for management frame protection
165 * RADIUS server: added support for processing duplicate messages
166 (retransmissions from RADIUS client) by replying with the previous
170 * added support for configuring and controlling multiple BSSes per
171 radio interface (bss=<ifname> in hostapd.conf); this is only
172 available with Devicescape and test driver interfaces
173 * fixed PMKSA cache update in the end of successful RSN
175 * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
176 for each STA based on RADIUS Access-Accept attributes); this requires
177 VLAN support from the kernel driver/802.11 stack and this is
178 currently only available with Devicescape and test driver interfaces
179 * driver_madwifi: fixed configuration of unencrypted modes (plaintext
180 and IEEE 802.1X without WEP)
181 * removed STAKey handshake since PeerKey handshake has replaced it in
182 IEEE 802.11ma and there are no known deployments of STAKey
183 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
184 draft (draft-ietf-emu-eap-gpsk-01.txt)
185 * added preliminary implementation of IEEE 802.11w/D1.0 (management
187 (Note: this requires driver support to work properly.)
188 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
189 * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
190 * hlr_auc_gw: added support for reading per-IMSI Milenage keys and
191 parameters from a text file to make it possible to implement proper
192 GSM/UMTS authentication server for multiple SIM/USIM cards using
194 * fixed session timeout processing with drivers that do not use
195 ieee802_11.c (e.g., madwifi)
198 * added 'hostapd_cli new_sta <addr>' command for adding a new STA into
199 hostapd (e.g., to initialize wired network authentication based on an
201 * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
202 using WPA2 even if PMKSA caching is not used
203 * added -P<pid file> argument for hostapd to write the current process
205 * added support for RADIUS Authentication Server MIB (RFC 2619)
208 * fixed nt_password_hash build [Bug 144]
209 * added PeerKey handshake implementation for IEEE 802.11e
210 direct link setup (DLS) to replace STAKey handshake
211 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
212 draft-clancy-emu-eap-shared-secret-00.txt)
213 * fixed a segmentation fault when RSN pre-authentication was completed
214 successfully [Bug 152]
217 * do not build nt_password_hash and hlr_auc_gw by default to avoid
218 requiring a TLS library for a successful build; these programs can be
219 build with 'make nt_password_hash' and 'make hlr_auc_gw'
220 * added a new configuration option, eapol_version, that can be used to
221 set EAPOL version to 1 (default is 2) to work around broken client
222 implementations that drop EAPOL frames which use version number 2
224 * added support for EAP-SAKE (no EAP method number allocated yet, so
225 this is using the same experimental type 255 as EAP-PSK)
226 * fixed EAP-MSCHAPv2 message length validation
229 * fixed stdarg use in hostapd_logger(): if both stdout and syslog
230 logging was enabled, hostapd could trigger a segmentation fault in
231 vsyslog on some CPU -- C library combinations
232 * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
233 program to make it easier to use for implementing real SS7 gateway;
234 eap_sim_db is not anymore used as a file name for GSM authentication
235 triplets; instead, it is path to UNIX domain socket that will be used
236 to communicate with the external gateway program (e.g., hlr_auc_gw)
237 * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
238 local information (GSM authentication triplets from a text file and
239 hardcoded AKA authentication data); this can be used to test EAP-SIM
241 * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
242 to make it possible to test EAP-AKA with real USIM cards (this is
243 disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
245 * driver_madwifi: added support for getting station RSN IE from
246 madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
247 broken with earlier change (r1357) in the driver
248 * changed EAP method registration to use a dynamic list of methods
249 instead of a static list generated at build time
250 * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
252 * added ap_max_inactivity configuration parameter
255 * driver_test: added better support for multiple APs and STAs by using
256 a directory with sockets that include MAC address for each device in
257 the name (test_socket=DIR:/tmp/test)
258 * added support for EAP expanded type (vendor specific EAP methods)
260 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
261 * added experimental STAKey handshake implementation for IEEE 802.11e
262 direct link setup (DLS); note: this is disabled by default in both
263 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
265 * added support for EAP methods to use callbacks to external programs
266 by buffering a pending request and processing it after the EAP method
268 * improved EAP-SIM database interface to allow external request to GSM
269 HLR/AuC without blocking hostapd process
270 * added support for using EAP-SIM pseudonyms and fast re-authentication
271 * added support for EAP-AKA in the integrated EAP authenticator
272 * added support for matching EAP identity prefixes (e.g., "1"*) in EAP
273 user database to allow EAP-SIM/AKA selection without extra roundtrip
274 for EAP-Nak negotiation
275 * added support for storing EAP user password as NtPasswordHash instead
276 of plaintext password when using MSCHAP or MSCHAPv2 for
277 authentication (hash:<16-octet hex value>); added nt_password_hash
278 tool for hashing password to generate NtPasswordHash
280 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
281 * driver_wired: fixed EAPOL sending to optionally use PAE group address
282 as the destination instead of supplicant MAC address; this is
283 disabled by default, but should be enabled with use_pae_group_addr=1
284 in configuration file if the wired interface is used by only one
285 device at the time (common switch configuration)
286 * driver_madwifi: configure driver to use TKIP countermeasures in order
287 to get correct behavior (IEEE 802.11 association failing; previously,
288 association succeeded, but hostpad forced disassociation immediately)
289 * driver_madwifi: added support for madwifi-ng
292 * added support for replacing user identity from EAP with RADIUS
293 User-Name attribute from Access-Accept message, if that is included,
294 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
295 tunneled identity into accounting messages when the RADIUS server
296 does not support better way of doing this with Class attribute)
297 * driver_madwifi: fixed EAPOL packet receive for configuration where
298 ath# is part of a bridge interface
299 * added a configuration file and log analyzer script for logwatch
300 * fixed EAPOL state machine step function to process all state
301 transitions before processing new events; this resolves a race
302 condition in which EAPOL-Start message could trigger hostapd to send
303 two EAP-Response/Identity frames to the authentication server
306 * added client CA list to the TLS certificate request in order to make
307 it easier for the client to select which certificate to use
308 * added experimental support for EAP-PSK
309 * added support for WE-19 (hostap, madwifi)
312 * fixed build without CONFIG_RSN_PREAUTH
313 * fixed FreeBSD build
316 * fixed PMKSA caching to copy User-Name and Class attributes so that
317 RADIUS accounting gets correct information
318 * start RADIUS accounting only after successful completion of WPA
319 4-Way Handshake if WPA-PSK is used
320 * fixed PMKSA caching for the case where STA (re)associates without
324 * EAP-PAX is now registered as EAP type 46
325 * fixed EAP-PAX MAC calculation
326 * fixed EAP-PAX CK and ICK key derivation
327 * renamed eap_authenticator configuration variable to eap_server to
328 better match with RFC 3748 (EAP) terminology
329 * driver_test: added support for testing hostapd with wpa_supplicant
330 by using test driver interface without any kernel drivers or network
334 * fixed RADIUS server initialization when only auth or acct server
335 is configured and the other one is left empty
336 * driver_madwifi: added support for RADIUS accounting
337 * driver_madwifi: added preliminary support for compiling against 'BSD'
338 branch of madwifi CVS tree
339 * driver_madwifi: fixed pairwise key removal to allow WPA reauth
340 without disassociation
341 * added support for reading additional certificates from PKCS#12 files
342 and adding them to the certificate chain
343 * fixed RADIUS Class attribute processing to only use Access-Accept
344 packets to update Class; previously, other RADIUS authentication
345 packets could have cleared Class attribute
346 * added support for more than one Class attribute in RADIUS packets
347 * added support for verifying certificate revocation list (CRL) when
348 using integrated EAP authenticator for EAP-TLS; new hostapd.conf
349 options 'check_crl'; CRL must be included in the ca_cert file for now
351 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
352 * added support for including network information into
353 EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
354 (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
355 * fixed a bug which caused some RSN pre-authentication cases to use
356 freed memory and potentially crash hostapd
357 * fixed private key loading for cases where passphrase is not set
358 * added support for sending TLS alerts and aborting authentication
359 when receiving a TLS alert
360 * fixed WPA2 to add PMKSA cache entry when using integrated EAP
362 * fixed PMKSA caching (EAP authentication was not skipped correctly
363 with the new state machine changes from IEEE 802.1X draft)
364 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
365 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
366 to be added to .config to include IPv6 support); for RADIUS server,
367 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
368 in RADIUS clients file can then use IPv6 format
369 * added experimental support for EAP-PAX
370 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with
371 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
373 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
376 * added support for configuring a forced PEAP version based on the
378 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
379 to terminate authentication
380 * fixed EAP identifier duplicate processing with the new IEEE 802.1X
382 * clear accounting data in the driver when starting a new accounting
384 * driver_madwifi: filter wireless events based on ifindex to allow more
385 than one network interface to be used
386 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
387 setting if the packet does not pass MIC verification (e.g., due to
388 incorrect PSK); previously, message 1/4 was not tried again if an
389 invalid message 2/4 was received
390 * fixed reconfiguration of RADIUS client retransmission timer when
391 adding a new message to the pending list; previously, timer was not
392 updated at this point and if there was a pending message with long
393 time for the next retry, the new message needed to wait that long for
397 * added support for configuring multiple allowed EAP types for Phase 2
398 authentication (EAP-PEAP, EAP-TTLS)
399 * fixed EAPOL-Start processing to trigger WPA reauthentication
400 (previously, only EAPOL authentication was done)
403 * added support for EAP-PEAP in the integrated EAP authenticator
404 * added support for EAP-GTC in the integrated EAP authenticator
405 * added support for configuring list of EAP methods for Phase 1 so that
406 the integrated EAP authenticator can, e.g., use the wildcard entry
407 for EAP-TLS and EAP-PEAP
408 * added support for EAP-TTLS in the integrated EAP authenticator
409 * added support for EAP-SIM in the integrated EAP authenticator
410 * added support for using hostapd as a RADIUS authentication server
411 with the integrated EAP authenticator taking care of EAP
412 authentication (new hostapd.conf options: radius_server_clients and
413 radius_server_auth_port); this is not included in default build; use
414 CONFIG_RADIUS_SERVER=y in .config to include
417 * removed 'daemonize' configuration file option since it has not really
418 been used at all for more than year
419 * driver_madwifi: fixed group key setup and added get_ssid method
420 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator
423 * added support for integrated EAP-TLS authentication (new hostapd.conf
424 variables: ca_cert, server_cert, private_key, private_key_passwd);
425 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
426 external RADIUS server
427 * added support for reading PKCS#12 (PFX) files (as a replacement for
428 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
430 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
431 * added support for Acct-{Input,Output}-Gigawords
432 * added support for Event-Timestamp (in RADIUS Accounting-Requests)
433 * added support for RADIUS Authentication Client MIB (RFC2618)
434 * added support for RADIUS Accounting Client MIB (RFC2620)
435 * made EAP re-authentication period configurable (eap_reauth_period)
436 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
437 * fixed EAPOL state machine to stop if STA is removed during
438 eapol_sm_step(); this fixes at least one segfault triggering bug with
439 IEEE 802.11i pre-authentication
440 * added support for multiple WPA pre-shared keys (e.g., one for each
441 client MAC address or keys shared by a group of clients);
442 new hostapd.conf field wpa_psk_file for setting path to a text file
443 containing PSKs, see hostapd.wpa_psk for an example
444 * added support for multiple driver interfaces to allow hostapd to be
445 used with other drivers
446 * added wired authenticator driver interface (driver=wired in
447 hostapd.conf, see wired.conf for example configuration)
448 * added madwifi driver interface (driver=madwifi in hostapd.conf, see
449 madwifi.conf for example configuration; Note: include files from
450 madwifi project is needed for building and a configuration file,
451 .config, needs to be created in hostapd directory with
452 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
454 * fixed an alignment issue that could cause SHA-1 to fail on some
455 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
457 * fixed RADIUS reconnection after an error in sending interim
459 * added hostapd control interface for external programs and an example
460 CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
461 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
462 'hostapd_cli sta <addr>')
463 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
464 * added support for strict GTK rekeying (wpa_strict_rekey in
466 * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
467 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
469 * added Prism54 driver interface (driver=prism54 in hostapd.conf;
470 note: .config needs to be created in hostapd directory with
471 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
473 * dual-licensed hostapd (GPLv2 and BSD licenses)
474 * fixed RADIUS accounting to generate a new session id for cases where
475 a station reassociates without first being complete deauthenticated
476 * fixed STA disassociation handler to mark next timeout state to
477 deauthenticate the station, i.e., skip long wait for inactivity poll
478 and extra disassociation, if the STA disassociates without
480 * added integrated EAP authenticator that can be used instead of
481 external RADIUS authentication server; currently, only EAP-MD5 is
482 supported, so this cannot yet be used for key distribution; the EAP
483 method interface is generic, though, so adding new EAP methods should
484 be straightforward; new hostapd.conf variables: 'eap_authenticator'
485 and 'eap_user_file'; this obsoletes "minimal authentication server"
486 ('minimal_eap' in hostapd.conf) which is now removed
487 * added support for FreeBSD and driver interface for the BSD net80211
488 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
489 .config); please note that some of the required kernel mods have not
492 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
493 * fixed some accounting cases where Accounting-Start was sent when
494 IEEE 802.1X port was being deauthorized
497 * modified RADIUS client to re-connect the socket in case of certain
498 error codes that are generated when a network interface state is
499 changes (e.g., when IP address changes or the interface is set UP)
500 * fixed couple of cases where EAPOL state for a station was freed
501 twice causing a segfault for hostapd
502 * fixed couple of bugs in processing WPA deauthentication (freed data
506 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
507 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
508 cases where STAs dropped multicast frames as replay attacks
509 * added support for copying RADIUS Attribute 'Class' from
510 authentication messages into accounting messages
511 * send canned EAP failure if RADIUS server sends Access-Reject without
512 EAP message (previously, Supplicant was not notified in this case)
513 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
514 not start EAPOL state machines if the STA selected to use WPA-PSK)
517 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
518 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
519 (i.e., IEEE 802.11i/D3.0)
520 - supports WPA-only, RSN-only, and mixed WPA/RSN mode
521 - both WPA-PSK and WPA-RADIUS/EAP are supported
522 - PMKSA caching and pre-authentication
523 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
524 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
525 rsn_preauth, rsn_preauth_interfaces
526 * fixed interim accounting to remove any pending accounting messages
527 to the STA before sending a new one
530 * added support for Acct-Interim-Interval:
531 - draft-ietf-radius-acct-interim-01.txt
532 - use Acct-Interim-Interval attribute from Access-Accept if local
533 'radius_acct_interim_interval' is not set
534 - allow different update intervals for each STA
535 * fixed event loop to call signal handlers only after returning from
536 the real signal handler
537 * reset sta->timeout_next after successful association to make sure
538 that the previously registered inactivity timer will not remove the
539 STA immediately (e.g., if STA deauthenticates and re-associates
540 before the timer is triggered).
541 * added new hostapd.conf variable, nas_identifier, that can be used to
542 add an optional RADIUS Attribute, NAS-Identifier, into authentication
543 and accounting messages
544 * added support for Accounting-On and Accounting-Off messages
545 * fixed accounting session handling to send Accounting-Start only once
546 per session and not to send Accounting-Stop if the session was not
548 * fixed Accounting-Stop statistics in cases where the message was
549 previously sent after the kernel entry for the STA (and/or IEEE
550 802.1X data) was removed
555 Older changes up to and including v0.1.0 are included in the ChangeLog
556 of the Host AP driver.
