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 configuration WPS negotiation; see README-WPS for
15 * added a new configuration option, wpa_ptk_rekey, that can be used to
16 enforce frequent PTK rekeying, e.g., to mitigate some attacks against
18 * updated OpenSSL code for EAP-FAST to use an updated version of the
19 session ticket overriding API that was included into the upstream
20 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
21 needed with that version anymore)
22 * changed channel flags configuration to read the information from
23 the driver (e.g., via driver_nl80211 when using mac80211) instead of
24 using hostapd as the source of the regulatory information (i.e.,
25 information from CRDA is now used with mac80211); this allows 5 GHz
26 channels to be used with hostapd (if allowed in the current
28 * fixed EAP-TLS message processing for the last TLS message if it is
29 large enough to require fragmentation (e.g., if a large Session
30 Ticket data is included)
31 * fixed listen interval configuration for nl80211 drivers
34 * added support for SHA-256 as X.509 certificate digest when using the
35 internal X.509/TLSv1 implementation
36 * fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer
38 * fixed internal TLSv1 implementation for abbreviated handshake (used
40 * added support for setting VLAN ID for STAs based on local MAC ACL
41 (accept_mac_file) as an alternative for RADIUS server-based
43 * updated management frame protection to use IEEE 802.11w/D6.0
44 (adds a new association ping to protect against unauthenticated
45 authenticate or (re)associate request frames dropping association)
46 * added support for using SHA256-based stronger key derivation for WPA2
48 * added new "driver wrapper" for RADIUS-only configuration
49 (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config)
50 * fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2)
51 is enabled in configuration
52 * changed EAP-FAST configuration to use separate fields for A-ID and
53 A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed
54 16-octet len binary value for better interoperability with some peer
55 implementations; eap_fast_a_id is now configured as a hex string
56 * driver_nl80211: Updated to match the current Linux mac80211 AP mode
57 configuration (wireless-testing.git and Linux kernel releases
61 * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2
62 Identity Request if identity is already known
63 * added support for EAP Sequences in EAP-FAST Phase 2
64 * added support for EAP-TNC (Trusted Network Connect)
65 (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST
66 changes needed to run two methods in sequence (IF-T) and the IF-IMV
67 and IF-TNCCS interfaces from TNCS)
68 * added support for optional cryptobinding with PEAPv0
69 * added fragmentation support for EAP-TNC
70 * added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled)
72 * added support for opportunistic key caching (OKC)
75 * fixed Reassociation Response callback processing when using internal
76 MLME (driver_{hostap,nl80211,test}.c)
77 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
78 * copy optional Proxy-State attributes into RADIUS response when acting
79 as a RADIUS authentication server
80 * fixed EAPOL state machine to handle a case in which no response is
81 received from the RADIUS authentication server; previous version
82 could have triggered a crash in some cases after a timeout
83 * fixed EAP-SIM/AKA realm processing to allow decorated usernames to
85 * added a workaround for EAP-SIM/AKA peers that include incorrect null
86 termination in the username
87 * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER
88 attribute in notification messages only when using fast
90 * fixed EAP-SIM Start response processing for fast reauthentication
92 * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST}
93 phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method
96 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
97 lengths properly to avoid potential crash caused by invalid messages
98 * added data structure for storing allocated buffers (struct wpabuf);
99 this does not affect hostapd usage, but many of the APIs changed
100 and various interfaces (e.g., EAP) is not compatible with old
102 * added support for protecting EAP-AKA/Identity messages with
103 AT_CHECKCODE (optional feature in RFC 4187)
104 * added support for protected result indication with AT_RESULT_IND for
105 EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1)
106 * added support for configuring EAP-TTLS phase 2 non-EAP methods in
107 EAP server configuration; previously all four were enabled for every
108 phase 2 user, now all four are disabled by default and need to be
109 enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP,
111 * removed old debug printing mechanism and the related 'debug'
112 parameter in the configuration file; debug verbosity is now set with
113 -d (or -dd) command line arguments
114 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
115 only shared key/password authentication is supported in this version
118 * added experimental, integrated TLSv1 server implementation with the
119 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
120 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
121 .config); this can be useful, e.g., if the target system does not
122 have a suitable TLS library and a minimal code size is required
123 * added support for EAP-FAST server method to the integrated EAP
125 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
126 draft (draft-ietf-emu-eap-gpsk-07.txt)
127 * added a new configuration parameter, rsn_pairwise, to allow different
128 pairwise cipher suites to be enabled for WPA and RSN/WPA2
129 (note: if wpa_pairwise differs from rsn_pairwise, the driver will
130 either need to support this or will have to use the WPA/RSN IEs from
131 hostapd; currently, the included madwifi and bsd driver interfaces do
132 not have support for this)
133 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
136 * added experimental IEEE 802.11r/D6.0 support
137 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
138 * updated EAP-PSK to use the IANA-allocated EAP type 47
139 * fixed EAP-PSK bit ordering of the Flags field
140 * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
141 by reading wpa_psk_file [Bug 181]
142 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
143 * fixed IPv6 connection to RADIUS accounting server
144 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
145 draft (draft-ietf-emu-eap-gpsk-04.txt)
146 * hlr_auc_gw: read GSM triplet file into memory and rotate through the
147 entries instead of only using the same three triplets every time
148 (this does not work properly with tests using multiple clients, but
149 provides bit better triplet data for testing a single client; anyway,
150 if a better quality triplets are needed, GSM-Milenage should be used
151 instead of hardcoded triplet file)
152 * fixed EAP-MSCHAPv2 server to use a space between S and M parameters
153 in Success Request [Bug 203]
154 * added support for sending EAP-AKA Notifications in error cases
155 * updated to use IEEE 802.11w/D2.0 for management frame protection
157 * RADIUS server: added support for processing duplicate messages
158 (retransmissions from RADIUS client) by replying with the previous
162 * added support for configuring and controlling multiple BSSes per
163 radio interface (bss=<ifname> in hostapd.conf); this is only
164 available with Devicescape and test driver interfaces
165 * fixed PMKSA cache update in the end of successful RSN
167 * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
168 for each STA based on RADIUS Access-Accept attributes); this requires
169 VLAN support from the kernel driver/802.11 stack and this is
170 currently only available with Devicescape and test driver interfaces
171 * driver_madwifi: fixed configuration of unencrypted modes (plaintext
172 and IEEE 802.1X without WEP)
173 * removed STAKey handshake since PeerKey handshake has replaced it in
174 IEEE 802.11ma and there are no known deployments of STAKey
175 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
176 draft (draft-ietf-emu-eap-gpsk-01.txt)
177 * added preliminary implementation of IEEE 802.11w/D1.0 (management
179 (Note: this requires driver support to work properly.)
180 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
181 * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
182 * hlr_auc_gw: added support for reading per-IMSI Milenage keys and
183 parameters from a text file to make it possible to implement proper
184 GSM/UMTS authentication server for multiple SIM/USIM cards using
186 * fixed session timeout processing with drivers that do not use
187 ieee802_11.c (e.g., madwifi)
190 * added 'hostapd_cli new_sta <addr>' command for adding a new STA into
191 hostapd (e.g., to initialize wired network authentication based on an
193 * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
194 using WPA2 even if PMKSA caching is not used
195 * added -P<pid file> argument for hostapd to write the current process
197 * added support for RADIUS Authentication Server MIB (RFC 2619)
200 * fixed nt_password_hash build [Bug 144]
201 * added PeerKey handshake implementation for IEEE 802.11e
202 direct link setup (DLS) to replace STAKey handshake
203 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
204 draft-clancy-emu-eap-shared-secret-00.txt)
205 * fixed a segmentation fault when RSN pre-authentication was completed
206 successfully [Bug 152]
209 * do not build nt_password_hash and hlr_auc_gw by default to avoid
210 requiring a TLS library for a successful build; these programs can be
211 build with 'make nt_password_hash' and 'make hlr_auc_gw'
212 * added a new configuration option, eapol_version, that can be used to
213 set EAPOL version to 1 (default is 2) to work around broken client
214 implementations that drop EAPOL frames which use version number 2
216 * added support for EAP-SAKE (no EAP method number allocated yet, so
217 this is using the same experimental type 255 as EAP-PSK)
218 * fixed EAP-MSCHAPv2 message length validation
221 * fixed stdarg use in hostapd_logger(): if both stdout and syslog
222 logging was enabled, hostapd could trigger a segmentation fault in
223 vsyslog on some CPU -- C library combinations
224 * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
225 program to make it easier to use for implementing real SS7 gateway;
226 eap_sim_db is not anymore used as a file name for GSM authentication
227 triplets; instead, it is path to UNIX domain socket that will be used
228 to communicate with the external gateway program (e.g., hlr_auc_gw)
229 * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
230 local information (GSM authentication triplets from a text file and
231 hardcoded AKA authentication data); this can be used to test EAP-SIM
233 * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
234 to make it possible to test EAP-AKA with real USIM cards (this is
235 disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
237 * driver_madwifi: added support for getting station RSN IE from
238 madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
239 broken with earlier change (r1357) in the driver
240 * changed EAP method registration to use a dynamic list of methods
241 instead of a static list generated at build time
242 * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
244 * added ap_max_inactivity configuration parameter
247 * driver_test: added better support for multiple APs and STAs by using
248 a directory with sockets that include MAC address for each device in
249 the name (test_socket=DIR:/tmp/test)
250 * added support for EAP expanded type (vendor specific EAP methods)
252 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
253 * added experimental STAKey handshake implementation for IEEE 802.11e
254 direct link setup (DLS); note: this is disabled by default in both
255 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
257 * added support for EAP methods to use callbacks to external programs
258 by buffering a pending request and processing it after the EAP method
260 * improved EAP-SIM database interface to allow external request to GSM
261 HLR/AuC without blocking hostapd process
262 * added support for using EAP-SIM pseudonyms and fast re-authentication
263 * added support for EAP-AKA in the integrated EAP authenticator
264 * added support for matching EAP identity prefixes (e.g., "1"*) in EAP
265 user database to allow EAP-SIM/AKA selection without extra roundtrip
266 for EAP-Nak negotiation
267 * added support for storing EAP user password as NtPasswordHash instead
268 of plaintext password when using MSCHAP or MSCHAPv2 for
269 authentication (hash:<16-octet hex value>); added nt_password_hash
270 tool for hashing password to generate NtPasswordHash
272 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
273 * driver_wired: fixed EAPOL sending to optionally use PAE group address
274 as the destination instead of supplicant MAC address; this is
275 disabled by default, but should be enabled with use_pae_group_addr=1
276 in configuration file if the wired interface is used by only one
277 device at the time (common switch configuration)
278 * driver_madwifi: configure driver to use TKIP countermeasures in order
279 to get correct behavior (IEEE 802.11 association failing; previously,
280 association succeeded, but hostpad forced disassociation immediately)
281 * driver_madwifi: added support for madwifi-ng
284 * added support for replacing user identity from EAP with RADIUS
285 User-Name attribute from Access-Accept message, if that is included,
286 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
287 tunneled identity into accounting messages when the RADIUS server
288 does not support better way of doing this with Class attribute)
289 * driver_madwifi: fixed EAPOL packet receive for configuration where
290 ath# is part of a bridge interface
291 * added a configuration file and log analyzer script for logwatch
292 * fixed EAPOL state machine step function to process all state
293 transitions before processing new events; this resolves a race
294 condition in which EAPOL-Start message could trigger hostapd to send
295 two EAP-Response/Identity frames to the authentication server
298 * added client CA list to the TLS certificate request in order to make
299 it easier for the client to select which certificate to use
300 * added experimental support for EAP-PSK
301 * added support for WE-19 (hostap, madwifi)
304 * fixed build without CONFIG_RSN_PREAUTH
305 * fixed FreeBSD build
308 * fixed PMKSA caching to copy User-Name and Class attributes so that
309 RADIUS accounting gets correct information
310 * start RADIUS accounting only after successful completion of WPA
311 4-Way Handshake if WPA-PSK is used
312 * fixed PMKSA caching for the case where STA (re)associates without
316 * EAP-PAX is now registered as EAP type 46
317 * fixed EAP-PAX MAC calculation
318 * fixed EAP-PAX CK and ICK key derivation
319 * renamed eap_authenticator configuration variable to eap_server to
320 better match with RFC 3748 (EAP) terminology
321 * driver_test: added support for testing hostapd with wpa_supplicant
322 by using test driver interface without any kernel drivers or network
326 * fixed RADIUS server initialization when only auth or acct server
327 is configured and the other one is left empty
328 * driver_madwifi: added support for RADIUS accounting
329 * driver_madwifi: added preliminary support for compiling against 'BSD'
330 branch of madwifi CVS tree
331 * driver_madwifi: fixed pairwise key removal to allow WPA reauth
332 without disassociation
333 * added support for reading additional certificates from PKCS#12 files
334 and adding them to the certificate chain
335 * fixed RADIUS Class attribute processing to only use Access-Accept
336 packets to update Class; previously, other RADIUS authentication
337 packets could have cleared Class attribute
338 * added support for more than one Class attribute in RADIUS packets
339 * added support for verifying certificate revocation list (CRL) when
340 using integrated EAP authenticator for EAP-TLS; new hostapd.conf
341 options 'check_crl'; CRL must be included in the ca_cert file for now
343 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
344 * added support for including network information into
345 EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
346 (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
347 * fixed a bug which caused some RSN pre-authentication cases to use
348 freed memory and potentially crash hostapd
349 * fixed private key loading for cases where passphrase is not set
350 * added support for sending TLS alerts and aborting authentication
351 when receiving a TLS alert
352 * fixed WPA2 to add PMKSA cache entry when using integrated EAP
354 * fixed PMKSA caching (EAP authentication was not skipped correctly
355 with the new state machine changes from IEEE 802.1X draft)
356 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
357 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
358 to be added to .config to include IPv6 support); for RADIUS server,
359 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
360 in RADIUS clients file can then use IPv6 format
361 * added experimental support for EAP-PAX
362 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with
363 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
365 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
368 * added support for configuring a forced PEAP version based on the
370 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
371 to terminate authentication
372 * fixed EAP identifier duplicate processing with the new IEEE 802.1X
374 * clear accounting data in the driver when starting a new accounting
376 * driver_madwifi: filter wireless events based on ifindex to allow more
377 than one network interface to be used
378 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
379 setting if the packet does not pass MIC verification (e.g., due to
380 incorrect PSK); previously, message 1/4 was not tried again if an
381 invalid message 2/4 was received
382 * fixed reconfiguration of RADIUS client retransmission timer when
383 adding a new message to the pending list; previously, timer was not
384 updated at this point and if there was a pending message with long
385 time for the next retry, the new message needed to wait that long for
389 * added support for configuring multiple allowed EAP types for Phase 2
390 authentication (EAP-PEAP, EAP-TTLS)
391 * fixed EAPOL-Start processing to trigger WPA reauthentication
392 (previously, only EAPOL authentication was done)
395 * added support for EAP-PEAP in the integrated EAP authenticator
396 * added support for EAP-GTC in the integrated EAP authenticator
397 * added support for configuring list of EAP methods for Phase 1 so that
398 the integrated EAP authenticator can, e.g., use the wildcard entry
399 for EAP-TLS and EAP-PEAP
400 * added support for EAP-TTLS in the integrated EAP authenticator
401 * added support for EAP-SIM in the integrated EAP authenticator
402 * added support for using hostapd as a RADIUS authentication server
403 with the integrated EAP authenticator taking care of EAP
404 authentication (new hostapd.conf options: radius_server_clients and
405 radius_server_auth_port); this is not included in default build; use
406 CONFIG_RADIUS_SERVER=y in .config to include
409 * removed 'daemonize' configuration file option since it has not really
410 been used at all for more than year
411 * driver_madwifi: fixed group key setup and added get_ssid method
412 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator
415 * added support for integrated EAP-TLS authentication (new hostapd.conf
416 variables: ca_cert, server_cert, private_key, private_key_passwd);
417 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
418 external RADIUS server
419 * added support for reading PKCS#12 (PFX) files (as a replacement for
420 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
422 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
423 * added support for Acct-{Input,Output}-Gigawords
424 * added support for Event-Timestamp (in RADIUS Accounting-Requests)
425 * added support for RADIUS Authentication Client MIB (RFC2618)
426 * added support for RADIUS Accounting Client MIB (RFC2620)
427 * made EAP re-authentication period configurable (eap_reauth_period)
428 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
429 * fixed EAPOL state machine to stop if STA is removed during
430 eapol_sm_step(); this fixes at least one segfault triggering bug with
431 IEEE 802.11i pre-authentication
432 * added support for multiple WPA pre-shared keys (e.g., one for each
433 client MAC address or keys shared by a group of clients);
434 new hostapd.conf field wpa_psk_file for setting path to a text file
435 containing PSKs, see hostapd.wpa_psk for an example
436 * added support for multiple driver interfaces to allow hostapd to be
437 used with other drivers
438 * added wired authenticator driver interface (driver=wired in
439 hostapd.conf, see wired.conf for example configuration)
440 * added madwifi driver interface (driver=madwifi in hostapd.conf, see
441 madwifi.conf for example configuration; Note: include files from
442 madwifi project is needed for building and a configuration file,
443 .config, needs to be created in hostapd directory with
444 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
446 * fixed an alignment issue that could cause SHA-1 to fail on some
447 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
449 * fixed RADIUS reconnection after an error in sending interim
451 * added hostapd control interface for external programs and an example
452 CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
453 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
454 'hostapd_cli sta <addr>')
455 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
456 * added support for strict GTK rekeying (wpa_strict_rekey in
458 * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
459 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
461 * added Prism54 driver interface (driver=prism54 in hostapd.conf;
462 note: .config needs to be created in hostapd directory with
463 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
465 * dual-licensed hostapd (GPLv2 and BSD licenses)
466 * fixed RADIUS accounting to generate a new session id for cases where
467 a station reassociates without first being complete deauthenticated
468 * fixed STA disassociation handler to mark next timeout state to
469 deauthenticate the station, i.e., skip long wait for inactivity poll
470 and extra disassociation, if the STA disassociates without
472 * added integrated EAP authenticator that can be used instead of
473 external RADIUS authentication server; currently, only EAP-MD5 is
474 supported, so this cannot yet be used for key distribution; the EAP
475 method interface is generic, though, so adding new EAP methods should
476 be straightforward; new hostapd.conf variables: 'eap_authenticator'
477 and 'eap_user_file'; this obsoletes "minimal authentication server"
478 ('minimal_eap' in hostapd.conf) which is now removed
479 * added support for FreeBSD and driver interface for the BSD net80211
480 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
481 .config); please note that some of the required kernel mods have not
484 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
485 * fixed some accounting cases where Accounting-Start was sent when
486 IEEE 802.1X port was being deauthorized
489 * modified RADIUS client to re-connect the socket in case of certain
490 error codes that are generated when a network interface state is
491 changes (e.g., when IP address changes or the interface is set UP)
492 * fixed couple of cases where EAPOL state for a station was freed
493 twice causing a segfault for hostapd
494 * fixed couple of bugs in processing WPA deauthentication (freed data
498 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
499 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
500 cases where STAs dropped multicast frames as replay attacks
501 * added support for copying RADIUS Attribute 'Class' from
502 authentication messages into accounting messages
503 * send canned EAP failure if RADIUS server sends Access-Reject without
504 EAP message (previously, Supplicant was not notified in this case)
505 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
506 not start EAPOL state machines if the STA selected to use WPA-PSK)
509 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
510 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
511 (i.e., IEEE 802.11i/D3.0)
512 - supports WPA-only, RSN-only, and mixed WPA/RSN mode
513 - both WPA-PSK and WPA-RADIUS/EAP are supported
514 - PMKSA caching and pre-authentication
515 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
516 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
517 rsn_preauth, rsn_preauth_interfaces
518 * fixed interim accounting to remove any pending accounting messages
519 to the STA before sending a new one
522 * added support for Acct-Interim-Interval:
523 - draft-ietf-radius-acct-interim-01.txt
524 - use Acct-Interim-Interval attribute from Access-Accept if local
525 'radius_acct_interim_interval' is not set
526 - allow different update intervals for each STA
527 * fixed event loop to call signal handlers only after returning from
528 the real signal handler
529 * reset sta->timeout_next after successful association to make sure
530 that the previously registered inactivity timer will not remove the
531 STA immediately (e.g., if STA deauthenticates and re-associates
532 before the timer is triggered).
533 * added new hostapd.conf variable, nas_identifier, that can be used to
534 add an optional RADIUS Attribute, NAS-Identifier, into authentication
535 and accounting messages
536 * added support for Accounting-On and Accounting-Off messages
537 * fixed accounting session handling to send Accounting-Start only once
538 per session and not to send Accounting-Stop if the session was not
540 * fixed Accounting-Stop statistics in cases where the message was
541 previously sent after the kernel entry for the STA (and/or IEEE
542 802.1X data) was removed
547 Older changes up to and including v0.1.0 are included in the ChangeLog
548 of the Host AP driver.
