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 * 802.11n: scan for overlapping BSSes before starting 20/40 MHz channel
11 * added support for Wi-Fi Protected Setup (WPS)
12 (hostapd can now be configured to act as an integrated WPS Registrar
13 and provision credentials for WPS Enrollees using PIN and PBC
14 methods; external wireless Registrar can configure the AP, but
15 external WLAN Manager Registrars are not supported); WPS support can
16 be enabled by adding CONFIG_WPS=y into .config and setting the
17 runtime configuration variables in hostapd.conf (see WPS section in
18 the example configuration file); new hostapd_cli commands wps_pin and
19 wps_pbc are used to configure WPS negotiation; see README-WPS for
21 * added IEEE 802.11n HT capability configuration (ht_capab)
22 * added support for generating Country IE based on nl80211 regulatory
23 information (added if ieee80211d=1 in configuration)

26 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
27 * added support for using driver_test over UDP socket
28 * changed EAP-GPSK to use the IANA assigned EAP method type 51
29 * updated management frame protection to use IEEE 802.11w/D7.0
30 * fixed retransmission of EAP requests if no response is received
33 * added a new configuration option, wpa_ptk_rekey, that can be used to
34 enforce frequent PTK rekeying, e.g., to mitigate some attacks against
36 * updated OpenSSL code for EAP-FAST to use an updated version of the
37 session ticket overriding API that was included into the upstream
38 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
39 needed with that version anymore)
40 * changed channel flags configuration to read the information from
41 the driver (e.g., via driver_nl80211 when using mac80211) instead of
42 using hostapd as the source of the regulatory information (i.e.,
43 information from CRDA is now used with mac80211); this allows 5 GHz
44 channels to be used with hostapd (if allowed in the current
46 * fixed EAP-TLS message processing for the last TLS message if it is
47 large enough to require fragmentation (e.g., if a large Session
48 Ticket data is included)
49 * fixed listen interval configuration for nl80211 drivers
52 * added support for SHA-256 as X.509 certificate digest when using the
53 internal X.509/TLSv1 implementation
54 * fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer
56 * fixed internal TLSv1 implementation for abbreviated handshake (used
58 * added support for setting VLAN ID for STAs based on local MAC ACL
59 (accept_mac_file) as an alternative for RADIUS server-based
61 * updated management frame protection to use IEEE 802.11w/D6.0
62 (adds a new association ping to protect against unauthenticated
63 authenticate or (re)associate request frames dropping association)
64 * added support for using SHA256-based stronger key derivation for WPA2
66 * added new "driver wrapper" for RADIUS-only configuration
67 (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config)
68 * fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2)
69 is enabled in configuration
70 * changed EAP-FAST configuration to use separate fields for A-ID and
71 A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed
72 16-octet len binary value for better interoperability with some peer
73 implementations; eap_fast_a_id is now configured as a hex string
74 * driver_nl80211: Updated to match the current Linux mac80211 AP mode
75 configuration (wireless-testing.git and Linux kernel releases
79 * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2
80 Identity Request if identity is already known
81 * added support for EAP Sequences in EAP-FAST Phase 2
82 * added support for EAP-TNC (Trusted Network Connect)
83 (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST
84 changes needed to run two methods in sequence (IF-T) and the IF-IMV
85 and IF-TNCCS interfaces from TNCS)
86 * added support for optional cryptobinding with PEAPv0
87 * added fragmentation support for EAP-TNC
88 * added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled)
90 * added support for opportunistic key caching (OKC)
93 * fixed Reassociation Response callback processing when using internal
94 MLME (driver_{hostap,nl80211,test}.c)
95 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
96 * copy optional Proxy-State attributes into RADIUS response when acting
97 as a RADIUS authentication server
98 * fixed EAPOL state machine to handle a case in which no response is
99 received from the RADIUS authentication server; previous version
100 could have triggered a crash in some cases after a timeout
101 * fixed EAP-SIM/AKA realm processing to allow decorated usernames to
103 * added a workaround for EAP-SIM/AKA peers that include incorrect null
104 termination in the username
105 * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER
106 attribute in notification messages only when using fast
108 * fixed EAP-SIM Start response processing for fast reauthentication
110 * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST}
111 phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method
114 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
115 lengths properly to avoid potential crash caused by invalid messages
116 * added data structure for storing allocated buffers (struct wpabuf);
117 this does not affect hostapd usage, but many of the APIs changed
118 and various interfaces (e.g., EAP) is not compatible with old
120 * added support for protecting EAP-AKA/Identity messages with
121 AT_CHECKCODE (optional feature in RFC 4187)
122 * added support for protected result indication with AT_RESULT_IND for
123 EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1)
124 * added support for configuring EAP-TTLS phase 2 non-EAP methods in
125 EAP server configuration; previously all four were enabled for every
126 phase 2 user, now all four are disabled by default and need to be
127 enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP,
129 * removed old debug printing mechanism and the related 'debug'
130 parameter in the configuration file; debug verbosity is now set with
131 -d (or -dd) command line arguments
132 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
133 only shared key/password authentication is supported in this version
136 * added experimental, integrated TLSv1 server implementation with the
137 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
138 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
139 .config); this can be useful, e.g., if the target system does not
140 have a suitable TLS library and a minimal code size is required
141 * added support for EAP-FAST server method to the integrated EAP
143 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
144 draft (draft-ietf-emu-eap-gpsk-07.txt)
145 * added a new configuration parameter, rsn_pairwise, to allow different
146 pairwise cipher suites to be enabled for WPA and RSN/WPA2
147 (note: if wpa_pairwise differs from rsn_pairwise, the driver will
148 either need to support this or will have to use the WPA/RSN IEs from
149 hostapd; currently, the included madwifi and bsd driver interfaces do
150 not have support for this)
151 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
154 * added experimental IEEE 802.11r/D6.0 support
155 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
156 * updated EAP-PSK to use the IANA-allocated EAP type 47
157 * fixed EAP-PSK bit ordering of the Flags field
158 * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
159 by reading wpa_psk_file [Bug 181]
160 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
161 * fixed IPv6 connection to RADIUS accounting server
162 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
163 draft (draft-ietf-emu-eap-gpsk-04.txt)
164 * hlr_auc_gw: read GSM triplet file into memory and rotate through the
165 entries instead of only using the same three triplets every time
166 (this does not work properly with tests using multiple clients, but
167 provides bit better triplet data for testing a single client; anyway,
168 if a better quality triplets are needed, GSM-Milenage should be used
169 instead of hardcoded triplet file)
170 * fixed EAP-MSCHAPv2 server to use a space between S and M parameters
171 in Success Request [Bug 203]
172 * added support for sending EAP-AKA Notifications in error cases
173 * updated to use IEEE 802.11w/D2.0 for management frame protection
175 * RADIUS server: added support for processing duplicate messages
176 (retransmissions from RADIUS client) by replying with the previous
180 * added support for configuring and controlling multiple BSSes per
181 radio interface (bss=<ifname> in hostapd.conf); this is only
182 available with Devicescape and test driver interfaces
183 * fixed PMKSA cache update in the end of successful RSN
185 * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
186 for each STA based on RADIUS Access-Accept attributes); this requires
187 VLAN support from the kernel driver/802.11 stack and this is
188 currently only available with Devicescape and test driver interfaces
189 * driver_madwifi: fixed configuration of unencrypted modes (plaintext
190 and IEEE 802.1X without WEP)
191 * removed STAKey handshake since PeerKey handshake has replaced it in
192 IEEE 802.11ma and there are no known deployments of STAKey
193 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
194 draft (draft-ietf-emu-eap-gpsk-01.txt)
195 * added preliminary implementation of IEEE 802.11w/D1.0 (management
197 (Note: this requires driver support to work properly.)
198 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
199 * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
200 * hlr_auc_gw: added support for reading per-IMSI Milenage keys and
201 parameters from a text file to make it possible to implement proper
202 GSM/UMTS authentication server for multiple SIM/USIM cards using
204 * fixed session timeout processing with drivers that do not use
205 ieee802_11.c (e.g., madwifi)
208 * added 'hostapd_cli new_sta <addr>' command for adding a new STA into
209 hostapd (e.g., to initialize wired network authentication based on an
211 * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
212 using WPA2 even if PMKSA caching is not used
213 * added -P<pid file> argument for hostapd to write the current process
215 * added support for RADIUS Authentication Server MIB (RFC 2619)
218 * fixed nt_password_hash build [Bug 144]
219 * added PeerKey handshake implementation for IEEE 802.11e
220 direct link setup (DLS) to replace STAKey handshake
221 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
222 draft-clancy-emu-eap-shared-secret-00.txt)
223 * fixed a segmentation fault when RSN pre-authentication was completed
224 successfully [Bug 152]
227 * do not build nt_password_hash and hlr_auc_gw by default to avoid
228 requiring a TLS library for a successful build; these programs can be
229 build with 'make nt_password_hash' and 'make hlr_auc_gw'
230 * added a new configuration option, eapol_version, that can be used to
231 set EAPOL version to 1 (default is 2) to work around broken client
232 implementations that drop EAPOL frames which use version number 2
234 * added support for EAP-SAKE (no EAP method number allocated yet, so
235 this is using the same experimental type 255 as EAP-PSK)
236 * fixed EAP-MSCHAPv2 message length validation
239 * fixed stdarg use in hostapd_logger(): if both stdout and syslog
240 logging was enabled, hostapd could trigger a segmentation fault in
241 vsyslog on some CPU -- C library combinations
242 * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
243 program to make it easier to use for implementing real SS7 gateway;
244 eap_sim_db is not anymore used as a file name for GSM authentication
245 triplets; instead, it is path to UNIX domain socket that will be used
246 to communicate with the external gateway program (e.g., hlr_auc_gw)
247 * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
248 local information (GSM authentication triplets from a text file and
249 hardcoded AKA authentication data); this can be used to test EAP-SIM
251 * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
252 to make it possible to test EAP-AKA with real USIM cards (this is
253 disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
255 * driver_madwifi: added support for getting station RSN IE from
256 madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
257 broken with earlier change (r1357) in the driver
258 * changed EAP method registration to use a dynamic list of methods
259 instead of a static list generated at build time
260 * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
262 * added ap_max_inactivity configuration parameter
265 * driver_test: added better support for multiple APs and STAs by using
266 a directory with sockets that include MAC address for each device in
267 the name (test_socket=DIR:/tmp/test)
268 * added support for EAP expanded type (vendor specific EAP methods)
270 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
271 * added experimental STAKey handshake implementation for IEEE 802.11e
272 direct link setup (DLS); note: this is disabled by default in both
273 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
275 * added support for EAP methods to use callbacks to external programs
276 by buffering a pending request and processing it after the EAP method
278 * improved EAP-SIM database interface to allow external request to GSM
279 HLR/AuC without blocking hostapd process
280 * added support for using EAP-SIM pseudonyms and fast re-authentication
281 * added support for EAP-AKA in the integrated EAP authenticator
282 * added support for matching EAP identity prefixes (e.g., "1"*) in EAP
283 user database to allow EAP-SIM/AKA selection without extra roundtrip
284 for EAP-Nak negotiation
285 * added support for storing EAP user password as NtPasswordHash instead
286 of plaintext password when using MSCHAP or MSCHAPv2 for
287 authentication (hash:<16-octet hex value>); added nt_password_hash
288 tool for hashing password to generate NtPasswordHash
290 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
291 * driver_wired: fixed EAPOL sending to optionally use PAE group address
292 as the destination instead of supplicant MAC address; this is
293 disabled by default, but should be enabled with use_pae_group_addr=1
294 in configuration file if the wired interface is used by only one
295 device at the time (common switch configuration)
296 * driver_madwifi: configure driver to use TKIP countermeasures in order
297 to get correct behavior (IEEE 802.11 association failing; previously,
298 association succeeded, but hostpad forced disassociation immediately)
299 * driver_madwifi: added support for madwifi-ng
302 * added support for replacing user identity from EAP with RADIUS
303 User-Name attribute from Access-Accept message, if that is included,
304 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
305 tunneled identity into accounting messages when the RADIUS server
306 does not support better way of doing this with Class attribute)
307 * driver_madwifi: fixed EAPOL packet receive for configuration where
308 ath# is part of a bridge interface
309 * added a configuration file and log analyzer script for logwatch
310 * fixed EAPOL state machine step function to process all state
311 transitions before processing new events; this resolves a race
312 condition in which EAPOL-Start message could trigger hostapd to send
313 two EAP-Response/Identity frames to the authentication server
316 * added client CA list to the TLS certificate request in order to make
317 it easier for the client to select which certificate to use
318 * added experimental support for EAP-PSK
319 * added support for WE-19 (hostap, madwifi)
322 * fixed build without CONFIG_RSN_PREAUTH
323 * fixed FreeBSD build
326 * fixed PMKSA caching to copy User-Name and Class attributes so that
327 RADIUS accounting gets correct information
328 * start RADIUS accounting only after successful completion of WPA
329 4-Way Handshake if WPA-PSK is used
330 * fixed PMKSA caching for the case where STA (re)associates without
334 * EAP-PAX is now registered as EAP type 46
335 * fixed EAP-PAX MAC calculation
336 * fixed EAP-PAX CK and ICK key derivation
337 * renamed eap_authenticator configuration variable to eap_server to
338 better match with RFC 3748 (EAP) terminology
339 * driver_test: added support for testing hostapd with wpa_supplicant
340 by using test driver interface without any kernel drivers or network
344 * fixed RADIUS server initialization when only auth or acct server
345 is configured and the other one is left empty
346 * driver_madwifi: added support for RADIUS accounting
347 * driver_madwifi: added preliminary support for compiling against 'BSD'
348 branch of madwifi CVS tree
349 * driver_madwifi: fixed pairwise key removal to allow WPA reauth
350 without disassociation
351 * added support for reading additional certificates from PKCS#12 files
352 and adding them to the certificate chain
353 * fixed RADIUS Class attribute processing to only use Access-Accept
354 packets to update Class; previously, other RADIUS authentication
355 packets could have cleared Class attribute
356 * added support for more than one Class attribute in RADIUS packets
357 * added support for verifying certificate revocation list (CRL) when
358 using integrated EAP authenticator for EAP-TLS; new hostapd.conf
359 options 'check_crl'; CRL must be included in the ca_cert file for now
361 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
362 * added support for including network information into
363 EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
364 (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
365 * fixed a bug which caused some RSN pre-authentication cases to use
366 freed memory and potentially crash hostapd
367 * fixed private key loading for cases where passphrase is not set
368 * added support for sending TLS alerts and aborting authentication
369 when receiving a TLS alert
370 * fixed WPA2 to add PMKSA cache entry when using integrated EAP
372 * fixed PMKSA caching (EAP authentication was not skipped correctly
373 with the new state machine changes from IEEE 802.1X draft)
374 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
375 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
376 to be added to .config to include IPv6 support); for RADIUS server,
377 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
378 in RADIUS clients file can then use IPv6 format
379 * added experimental support for EAP-PAX
380 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with
381 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
383 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
386 * added support for configuring a forced PEAP version based on the
388 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
389 to terminate authentication
390 * fixed EAP identifier duplicate processing with the new IEEE 802.1X
392 * clear accounting data in the driver when starting a new accounting
394 * driver_madwifi: filter wireless events based on ifindex to allow more
395 than one network interface to be used
396 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
397 setting if the packet does not pass MIC verification (e.g., due to
398 incorrect PSK); previously, message 1/4 was not tried again if an
399 invalid message 2/4 was received
400 * fixed reconfiguration of RADIUS client retransmission timer when
401 adding a new message to the pending list; previously, timer was not
402 updated at this point and if there was a pending message with long
403 time for the next retry, the new message needed to wait that long for
407 * added support for configuring multiple allowed EAP types for Phase 2
408 authentication (EAP-PEAP, EAP-TTLS)
409 * fixed EAPOL-Start processing to trigger WPA reauthentication
410 (previously, only EAPOL authentication was done)
413 * added support for EAP-PEAP in the integrated EAP authenticator
414 * added support for EAP-GTC in the integrated EAP authenticator
415 * added support for configuring list of EAP methods for Phase 1 so that
416 the integrated EAP authenticator can, e.g., use the wildcard entry
417 for EAP-TLS and EAP-PEAP
418 * added support for EAP-TTLS in the integrated EAP authenticator
419 * added support for EAP-SIM in the integrated EAP authenticator
420 * added support for using hostapd as a RADIUS authentication server
421 with the integrated EAP authenticator taking care of EAP
422 authentication (new hostapd.conf options: radius_server_clients and
423 radius_server_auth_port); this is not included in default build; use
424 CONFIG_RADIUS_SERVER=y in .config to include
427 * removed 'daemonize' configuration file option since it has not really
428 been used at all for more than year
429 * driver_madwifi: fixed group key setup and added get_ssid method
430 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator
433 * added support for integrated EAP-TLS authentication (new hostapd.conf
434 variables: ca_cert, server_cert, private_key, private_key_passwd);
435 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
436 external RADIUS server
437 * added support for reading PKCS#12 (PFX) files (as a replacement for
438 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
440 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
441 * added support for Acct-{Input,Output}-Gigawords
442 * added support for Event-Timestamp (in RADIUS Accounting-Requests)
443 * added support for RADIUS Authentication Client MIB (RFC2618)
444 * added support for RADIUS Accounting Client MIB (RFC2620)
445 * made EAP re-authentication period configurable (eap_reauth_period)
446 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
447 * fixed EAPOL state machine to stop if STA is removed during
448 eapol_sm_step(); this fixes at least one segfault triggering bug with
449 IEEE 802.11i pre-authentication
450 * added support for multiple WPA pre-shared keys (e.g., one for each
451 client MAC address or keys shared by a group of clients);
452 new hostapd.conf field wpa_psk_file for setting path to a text file
453 containing PSKs, see hostapd.wpa_psk for an example
454 * added support for multiple driver interfaces to allow hostapd to be
455 used with other drivers
456 * added wired authenticator driver interface (driver=wired in
457 hostapd.conf, see wired.conf for example configuration)
458 * added madwifi driver interface (driver=madwifi in hostapd.conf, see
459 madwifi.conf for example configuration; Note: include files from
460 madwifi project is needed for building and a configuration file,
461 .config, needs to be created in hostapd directory with
462 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
464 * fixed an alignment issue that could cause SHA-1 to fail on some
465 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
467 * fixed RADIUS reconnection after an error in sending interim
469 * added hostapd control interface for external programs and an example
470 CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
471 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
472 'hostapd_cli sta <addr>')
473 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
474 * added support for strict GTK rekeying (wpa_strict_rekey in
476 * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
477 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
479 * added Prism54 driver interface (driver=prism54 in hostapd.conf;
480 note: .config needs to be created in hostapd directory with
481 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
483 * dual-licensed hostapd (GPLv2 and BSD licenses)
484 * fixed RADIUS accounting to generate a new session id for cases where
485 a station reassociates without first being complete deauthenticated
486 * fixed STA disassociation handler to mark next timeout state to
487 deauthenticate the station, i.e., skip long wait for inactivity poll
488 and extra disassociation, if the STA disassociates without
490 * added integrated EAP authenticator that can be used instead of
491 external RADIUS authentication server; currently, only EAP-MD5 is
492 supported, so this cannot yet be used for key distribution; the EAP
493 method interface is generic, though, so adding new EAP methods should
494 be straightforward; new hostapd.conf variables: 'eap_authenticator'
495 and 'eap_user_file'; this obsoletes "minimal authentication server"
496 ('minimal_eap' in hostapd.conf) which is now removed
497 * added support for FreeBSD and driver interface for the BSD net80211
498 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
499 .config); please note that some of the required kernel mods have not
502 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
503 * fixed some accounting cases where Accounting-Start was sent when
504 IEEE 802.1X port was being deauthorized
507 * modified RADIUS client to re-connect the socket in case of certain
508 error codes that are generated when a network interface state is
509 changes (e.g., when IP address changes or the interface is set UP)
510 * fixed couple of cases where EAPOL state for a station was freed
511 twice causing a segfault for hostapd
512 * fixed couple of bugs in processing WPA deauthentication (freed data
516 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
517 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
518 cases where STAs dropped multicast frames as replay attacks
519 * added support for copying RADIUS Attribute 'Class' from
520 authentication messages into accounting messages
521 * send canned EAP failure if RADIUS server sends Access-Reject without
522 EAP message (previously, Supplicant was not notified in this case)
523 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
524 not start EAPOL state machines if the STA selected to use WPA-PSK)
527 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
528 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
529 (i.e., IEEE 802.11i/D3.0)
530 - supports WPA-only, RSN-only, and mixed WPA/RSN mode
531 - both WPA-PSK and WPA-RADIUS/EAP are supported
532 - PMKSA caching and pre-authentication
533 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
534 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
535 rsn_preauth, rsn_preauth_interfaces
536 * fixed interim accounting to remove any pending accounting messages
537 to the STA before sending a new one
540 * added support for Acct-Interim-Interval:
541 - draft-ietf-radius-acct-interim-01.txt
542 - use Acct-Interim-Interval attribute from Access-Accept if local
543 'radius_acct_interim_interval' is not set
544 - allow different update intervals for each STA
545 * fixed event loop to call signal handlers only after returning from
546 the real signal handler
547 * reset sta->timeout_next after successful association to make sure
548 that the previously registered inactivity timer will not remove the
549 STA immediately (e.g., if STA deauthenticates and re-associates
550 before the timer is triggered).
551 * added new hostapd.conf variable, nas_identifier, that can be used to
552 add an optional RADIUS Attribute, NAS-Identifier, into authentication
553 and accounting messages
554 * added support for Accounting-On and Accounting-Off messages
555 * fixed accounting session handling to send Accounting-Start only once
556 per session and not to send Accounting-Stop if the session was not
558 * fixed Accounting-Stop statistics in cases where the message was
559 previously sent after the kernel entry for the STA (and/or IEEE
560 802.1X data) was removed
565 Older changes up to and including v0.1.0 are included in the ChangeLog
566 of the Host AP driver.
