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
21 * updated management frame protection to use IEEE 802.11w/D7.0
22 * fixed retransmission of EAP requests if no response is received
25 * added a new configuration option, wpa_ptk_rekey, that can be used to
26 enforce frequent PTK rekeying, e.g., to mitigate some attacks against
28 * updated OpenSSL code for EAP-FAST to use an updated version of the
29 session ticket overriding API that was included into the upstream
30 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
31 needed with that version anymore)
32 * changed channel flags configuration to read the information from
33 the driver (e.g., via driver_nl80211 when using mac80211) instead of
34 using hostapd as the source of the regulatory information (i.e.,
35 information from CRDA is now used with mac80211); this allows 5 GHz
36 channels to be used with hostapd (if allowed in the current
38 * fixed EAP-TLS message processing for the last TLS message if it is
39 large enough to require fragmentation (e.g., if a large Session
40 Ticket data is included)
41 * fixed listen interval configuration for nl80211 drivers
44 * added support for SHA-256 as X.509 certificate digest when using the
45 internal X.509/TLSv1 implementation
46 * fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer
48 * fixed internal TLSv1 implementation for abbreviated handshake (used
50 * added support for setting VLAN ID for STAs based on local MAC ACL
51 (accept_mac_file) as an alternative for RADIUS server-based
53 * updated management frame protection to use IEEE 802.11w/D6.0
54 (adds a new association ping to protect against unauthenticated
55 authenticate or (re)associate request frames dropping association)
56 * added support for using SHA256-based stronger key derivation for WPA2
58 * added new "driver wrapper" for RADIUS-only configuration
59 (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config)
60 * fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2)
61 is enabled in configuration
62 * changed EAP-FAST configuration to use separate fields for A-ID and
63 A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed
64 16-octet len binary value for better interoperability with some peer
65 implementations; eap_fast_a_id is now configured as a hex string
66 * driver_nl80211: Updated to match the current Linux mac80211 AP mode
67 configuration (wireless-testing.git and Linux kernel releases
71 * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2
72 Identity Request if identity is already known
73 * added support for EAP Sequences in EAP-FAST Phase 2
74 * added support for EAP-TNC (Trusted Network Connect)
75 (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST
76 changes needed to run two methods in sequence (IF-T) and the IF-IMV
77 and IF-TNCCS interfaces from TNCS)
78 * added support for optional cryptobinding with PEAPv0
79 * added fragmentation support for EAP-TNC
80 * added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled)
82 * added support for opportunistic key caching (OKC)
85 * fixed Reassociation Response callback processing when using internal
86 MLME (driver_{hostap,nl80211,test}.c)
87 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
88 * copy optional Proxy-State attributes into RADIUS response when acting
89 as a RADIUS authentication server
90 * fixed EAPOL state machine to handle a case in which no response is
91 received from the RADIUS authentication server; previous version
92 could have triggered a crash in some cases after a timeout
93 * fixed EAP-SIM/AKA realm processing to allow decorated usernames to
95 * added a workaround for EAP-SIM/AKA peers that include incorrect null
96 termination in the username
97 * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER
98 attribute in notification messages only when using fast
100 * fixed EAP-SIM Start response processing for fast reauthentication
102 * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST}
103 phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method
106 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
107 lengths properly to avoid potential crash caused by invalid messages
108 * added data structure for storing allocated buffers (struct wpabuf);
109 this does not affect hostapd usage, but many of the APIs changed
110 and various interfaces (e.g., EAP) is not compatible with old
112 * added support for protecting EAP-AKA/Identity messages with
113 AT_CHECKCODE (optional feature in RFC 4187)
114 * added support for protected result indication with AT_RESULT_IND for
115 EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1)
116 * added support for configuring EAP-TTLS phase 2 non-EAP methods in
117 EAP server configuration; previously all four were enabled for every
118 phase 2 user, now all four are disabled by default and need to be
119 enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP,
121 * removed old debug printing mechanism and the related 'debug'
122 parameter in the configuration file; debug verbosity is now set with
123 -d (or -dd) command line arguments
124 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
125 only shared key/password authentication is supported in this version
128 * added experimental, integrated TLSv1 server implementation with the
129 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
130 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
131 .config); this can be useful, e.g., if the target system does not
132 have a suitable TLS library and a minimal code size is required
133 * added support for EAP-FAST server method to the integrated EAP
135 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
136 draft (draft-ietf-emu-eap-gpsk-07.txt)
137 * added a new configuration parameter, rsn_pairwise, to allow different
138 pairwise cipher suites to be enabled for WPA and RSN/WPA2
139 (note: if wpa_pairwise differs from rsn_pairwise, the driver will
140 either need to support this or will have to use the WPA/RSN IEs from
141 hostapd; currently, the included madwifi and bsd driver interfaces do
142 not have support for this)
143 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
146 * added experimental IEEE 802.11r/D6.0 support
147 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
148 * updated EAP-PSK to use the IANA-allocated EAP type 47
149 * fixed EAP-PSK bit ordering of the Flags field
150 * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
151 by reading wpa_psk_file [Bug 181]
152 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
153 * fixed IPv6 connection to RADIUS accounting server
154 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
155 draft (draft-ietf-emu-eap-gpsk-04.txt)
156 * hlr_auc_gw: read GSM triplet file into memory and rotate through the
157 entries instead of only using the same three triplets every time
158 (this does not work properly with tests using multiple clients, but
159 provides bit better triplet data for testing a single client; anyway,
160 if a better quality triplets are needed, GSM-Milenage should be used
161 instead of hardcoded triplet file)
162 * fixed EAP-MSCHAPv2 server to use a space between S and M parameters
163 in Success Request [Bug 203]
164 * added support for sending EAP-AKA Notifications in error cases
165 * updated to use IEEE 802.11w/D2.0 for management frame protection
167 * RADIUS server: added support for processing duplicate messages
168 (retransmissions from RADIUS client) by replying with the previous
172 * added support for configuring and controlling multiple BSSes per
173 radio interface (bss=<ifname> in hostapd.conf); this is only
174 available with Devicescape and test driver interfaces
175 * fixed PMKSA cache update in the end of successful RSN
177 * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
178 for each STA based on RADIUS Access-Accept attributes); this requires
179 VLAN support from the kernel driver/802.11 stack and this is
180 currently only available with Devicescape and test driver interfaces
181 * driver_madwifi: fixed configuration of unencrypted modes (plaintext
182 and IEEE 802.1X without WEP)
183 * removed STAKey handshake since PeerKey handshake has replaced it in
184 IEEE 802.11ma and there are no known deployments of STAKey
185 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
186 draft (draft-ietf-emu-eap-gpsk-01.txt)
187 * added preliminary implementation of IEEE 802.11w/D1.0 (management
189 (Note: this requires driver support to work properly.)
190 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
191 * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
192 * hlr_auc_gw: added support for reading per-IMSI Milenage keys and
193 parameters from a text file to make it possible to implement proper
194 GSM/UMTS authentication server for multiple SIM/USIM cards using
196 * fixed session timeout processing with drivers that do not use
197 ieee802_11.c (e.g., madwifi)
200 * added 'hostapd_cli new_sta <addr>' command for adding a new STA into
201 hostapd (e.g., to initialize wired network authentication based on an
203 * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
204 using WPA2 even if PMKSA caching is not used
205 * added -P<pid file> argument for hostapd to write the current process
207 * added support for RADIUS Authentication Server MIB (RFC 2619)
210 * fixed nt_password_hash build [Bug 144]
211 * added PeerKey handshake implementation for IEEE 802.11e
212 direct link setup (DLS) to replace STAKey handshake
213 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
214 draft-clancy-emu-eap-shared-secret-00.txt)
215 * fixed a segmentation fault when RSN pre-authentication was completed
216 successfully [Bug 152]
219 * do not build nt_password_hash and hlr_auc_gw by default to avoid
220 requiring a TLS library for a successful build; these programs can be
221 build with 'make nt_password_hash' and 'make hlr_auc_gw'
222 * added a new configuration option, eapol_version, that can be used to
223 set EAPOL version to 1 (default is 2) to work around broken client
224 implementations that drop EAPOL frames which use version number 2
226 * added support for EAP-SAKE (no EAP method number allocated yet, so
227 this is using the same experimental type 255 as EAP-PSK)
228 * fixed EAP-MSCHAPv2 message length validation
231 * fixed stdarg use in hostapd_logger(): if both stdout and syslog
232 logging was enabled, hostapd could trigger a segmentation fault in
233 vsyslog on some CPU -- C library combinations
234 * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
235 program to make it easier to use for implementing real SS7 gateway;
236 eap_sim_db is not anymore used as a file name for GSM authentication
237 triplets; instead, it is path to UNIX domain socket that will be used
238 to communicate with the external gateway program (e.g., hlr_auc_gw)
239 * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
240 local information (GSM authentication triplets from a text file and
241 hardcoded AKA authentication data); this can be used to test EAP-SIM
243 * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
244 to make it possible to test EAP-AKA with real USIM cards (this is
245 disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
247 * driver_madwifi: added support for getting station RSN IE from
248 madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
249 broken with earlier change (r1357) in the driver
250 * changed EAP method registration to use a dynamic list of methods
251 instead of a static list generated at build time
252 * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
254 * added ap_max_inactivity configuration parameter
257 * driver_test: added better support for multiple APs and STAs by using
258 a directory with sockets that include MAC address for each device in
259 the name (test_socket=DIR:/tmp/test)
260 * added support for EAP expanded type (vendor specific EAP methods)
262 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
263 * added experimental STAKey handshake implementation for IEEE 802.11e
264 direct link setup (DLS); note: this is disabled by default in both
265 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
267 * added support for EAP methods to use callbacks to external programs
268 by buffering a pending request and processing it after the EAP method
270 * improved EAP-SIM database interface to allow external request to GSM
271 HLR/AuC without blocking hostapd process
272 * added support for using EAP-SIM pseudonyms and fast re-authentication
273 * added support for EAP-AKA in the integrated EAP authenticator
274 * added support for matching EAP identity prefixes (e.g., "1"*) in EAP
275 user database to allow EAP-SIM/AKA selection without extra roundtrip
276 for EAP-Nak negotiation
277 * added support for storing EAP user password as NtPasswordHash instead
278 of plaintext password when using MSCHAP or MSCHAPv2 for
279 authentication (hash:<16-octet hex value>); added nt_password_hash
280 tool for hashing password to generate NtPasswordHash
282 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
283 * driver_wired: fixed EAPOL sending to optionally use PAE group address
284 as the destination instead of supplicant MAC address; this is
285 disabled by default, but should be enabled with use_pae_group_addr=1
286 in configuration file if the wired interface is used by only one
287 device at the time (common switch configuration)
288 * driver_madwifi: configure driver to use TKIP countermeasures in order
289 to get correct behavior (IEEE 802.11 association failing; previously,
290 association succeeded, but hostpad forced disassociation immediately)
291 * driver_madwifi: added support for madwifi-ng
294 * added support for replacing user identity from EAP with RADIUS
295 User-Name attribute from Access-Accept message, if that is included,
296 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
297 tunneled identity into accounting messages when the RADIUS server
298 does not support better way of doing this with Class attribute)
299 * driver_madwifi: fixed EAPOL packet receive for configuration where
300 ath# is part of a bridge interface
301 * added a configuration file and log analyzer script for logwatch
302 * fixed EAPOL state machine step function to process all state
303 transitions before processing new events; this resolves a race
304 condition in which EAPOL-Start message could trigger hostapd to send
305 two EAP-Response/Identity frames to the authentication server
308 * added client CA list to the TLS certificate request in order to make
309 it easier for the client to select which certificate to use
310 * added experimental support for EAP-PSK
311 * added support for WE-19 (hostap, madwifi)
314 * fixed build without CONFIG_RSN_PREAUTH
315 * fixed FreeBSD build
318 * fixed PMKSA caching to copy User-Name and Class attributes so that
319 RADIUS accounting gets correct information
320 * start RADIUS accounting only after successful completion of WPA
321 4-Way Handshake if WPA-PSK is used
322 * fixed PMKSA caching for the case where STA (re)associates without
326 * EAP-PAX is now registered as EAP type 46
327 * fixed EAP-PAX MAC calculation
328 * fixed EAP-PAX CK and ICK key derivation
329 * renamed eap_authenticator configuration variable to eap_server to
330 better match with RFC 3748 (EAP) terminology
331 * driver_test: added support for testing hostapd with wpa_supplicant
332 by using test driver interface without any kernel drivers or network
336 * fixed RADIUS server initialization when only auth or acct server
337 is configured and the other one is left empty
338 * driver_madwifi: added support for RADIUS accounting
339 * driver_madwifi: added preliminary support for compiling against 'BSD'
340 branch of madwifi CVS tree
341 * driver_madwifi: fixed pairwise key removal to allow WPA reauth
342 without disassociation
343 * added support for reading additional certificates from PKCS#12 files
344 and adding them to the certificate chain
345 * fixed RADIUS Class attribute processing to only use Access-Accept
346 packets to update Class; previously, other RADIUS authentication
347 packets could have cleared Class attribute
348 * added support for more than one Class attribute in RADIUS packets
349 * added support for verifying certificate revocation list (CRL) when
350 using integrated EAP authenticator for EAP-TLS; new hostapd.conf
351 options 'check_crl'; CRL must be included in the ca_cert file for now
353 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
354 * added support for including network information into
355 EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
356 (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
357 * fixed a bug which caused some RSN pre-authentication cases to use
358 freed memory and potentially crash hostapd
359 * fixed private key loading for cases where passphrase is not set
360 * added support for sending TLS alerts and aborting authentication
361 when receiving a TLS alert
362 * fixed WPA2 to add PMKSA cache entry when using integrated EAP
364 * fixed PMKSA caching (EAP authentication was not skipped correctly
365 with the new state machine changes from IEEE 802.1X draft)
366 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
367 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
368 to be added to .config to include IPv6 support); for RADIUS server,
369 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
370 in RADIUS clients file can then use IPv6 format
371 * added experimental support for EAP-PAX
372 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with
373 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
375 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
378 * added support for configuring a forced PEAP version based on the
380 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
381 to terminate authentication
382 * fixed EAP identifier duplicate processing with the new IEEE 802.1X
384 * clear accounting data in the driver when starting a new accounting
386 * driver_madwifi: filter wireless events based on ifindex to allow more
387 than one network interface to be used
388 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
389 setting if the packet does not pass MIC verification (e.g., due to
390 incorrect PSK); previously, message 1/4 was not tried again if an
391 invalid message 2/4 was received
392 * fixed reconfiguration of RADIUS client retransmission timer when
393 adding a new message to the pending list; previously, timer was not
394 updated at this point and if there was a pending message with long
395 time for the next retry, the new message needed to wait that long for
399 * added support for configuring multiple allowed EAP types for Phase 2
400 authentication (EAP-PEAP, EAP-TTLS)
401 * fixed EAPOL-Start processing to trigger WPA reauthentication
402 (previously, only EAPOL authentication was done)
405 * added support for EAP-PEAP in the integrated EAP authenticator
406 * added support for EAP-GTC in the integrated EAP authenticator
407 * added support for configuring list of EAP methods for Phase 1 so that
408 the integrated EAP authenticator can, e.g., use the wildcard entry
409 for EAP-TLS and EAP-PEAP
410 * added support for EAP-TTLS in the integrated EAP authenticator
411 * added support for EAP-SIM in the integrated EAP authenticator
412 * added support for using hostapd as a RADIUS authentication server
413 with the integrated EAP authenticator taking care of EAP
414 authentication (new hostapd.conf options: radius_server_clients and
415 radius_server_auth_port); this is not included in default build; use
416 CONFIG_RADIUS_SERVER=y in .config to include
419 * removed 'daemonize' configuration file option since it has not really
420 been used at all for more than year
421 * driver_madwifi: fixed group key setup and added get_ssid method
422 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator
425 * added support for integrated EAP-TLS authentication (new hostapd.conf
426 variables: ca_cert, server_cert, private_key, private_key_passwd);
427 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
428 external RADIUS server
429 * added support for reading PKCS#12 (PFX) files (as a replacement for
430 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
432 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
433 * added support for Acct-{Input,Output}-Gigawords
434 * added support for Event-Timestamp (in RADIUS Accounting-Requests)
435 * added support for RADIUS Authentication Client MIB (RFC2618)
436 * added support for RADIUS Accounting Client MIB (RFC2620)
437 * made EAP re-authentication period configurable (eap_reauth_period)
438 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
439 * fixed EAPOL state machine to stop if STA is removed during
440 eapol_sm_step(); this fixes at least one segfault triggering bug with
441 IEEE 802.11i pre-authentication
442 * added support for multiple WPA pre-shared keys (e.g., one for each
443 client MAC address or keys shared by a group of clients);
444 new hostapd.conf field wpa_psk_file for setting path to a text file
445 containing PSKs, see hostapd.wpa_psk for an example
446 * added support for multiple driver interfaces to allow hostapd to be
447 used with other drivers
448 * added wired authenticator driver interface (driver=wired in
449 hostapd.conf, see wired.conf for example configuration)
450 * added madwifi driver interface (driver=madwifi in hostapd.conf, see
451 madwifi.conf for example configuration; Note: include files from
452 madwifi project is needed for building and a configuration file,
453 .config, needs to be created in hostapd directory with
454 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
456 * fixed an alignment issue that could cause SHA-1 to fail on some
457 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
459 * fixed RADIUS reconnection after an error in sending interim
461 * added hostapd control interface for external programs and an example
462 CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
463 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
464 'hostapd_cli sta <addr>')
465 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
466 * added support for strict GTK rekeying (wpa_strict_rekey in
468 * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
469 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
471 * added Prism54 driver interface (driver=prism54 in hostapd.conf;
472 note: .config needs to be created in hostapd directory with
473 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
475 * dual-licensed hostapd (GPLv2 and BSD licenses)
476 * fixed RADIUS accounting to generate a new session id for cases where
477 a station reassociates without first being complete deauthenticated
478 * fixed STA disassociation handler to mark next timeout state to
479 deauthenticate the station, i.e., skip long wait for inactivity poll
480 and extra disassociation, if the STA disassociates without
482 * added integrated EAP authenticator that can be used instead of
483 external RADIUS authentication server; currently, only EAP-MD5 is
484 supported, so this cannot yet be used for key distribution; the EAP
485 method interface is generic, though, so adding new EAP methods should
486 be straightforward; new hostapd.conf variables: 'eap_authenticator'
487 and 'eap_user_file'; this obsoletes "minimal authentication server"
488 ('minimal_eap' in hostapd.conf) which is now removed
489 * added support for FreeBSD and driver interface for the BSD net80211
490 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
491 .config); please note that some of the required kernel mods have not
494 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
495 * fixed some accounting cases where Accounting-Start was sent when
496 IEEE 802.1X port was being deauthorized
499 * modified RADIUS client to re-connect the socket in case of certain
500 error codes that are generated when a network interface state is
501 changes (e.g., when IP address changes or the interface is set UP)
502 * fixed couple of cases where EAPOL state for a station was freed
503 twice causing a segfault for hostapd
504 * fixed couple of bugs in processing WPA deauthentication (freed data
508 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
509 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
510 cases where STAs dropped multicast frames as replay attacks
511 * added support for copying RADIUS Attribute 'Class' from
512 authentication messages into accounting messages
513 * send canned EAP failure if RADIUS server sends Access-Reject without
514 EAP message (previously, Supplicant was not notified in this case)
515 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
516 not start EAPOL state machines if the STA selected to use WPA-PSK)
519 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
520 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
521 (i.e., IEEE 802.11i/D3.0)
522 - supports WPA-only, RSN-only, and mixed WPA/RSN mode
523 - both WPA-PSK and WPA-RADIUS/EAP are supported
524 - PMKSA caching and pre-authentication
525 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
526 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
527 rsn_preauth, rsn_preauth_interfaces
528 * fixed interim accounting to remove any pending accounting messages
529 to the STA before sending a new one
532 * added support for Acct-Interim-Interval:
533 - draft-ietf-radius-acct-interim-01.txt
534 - use Acct-Interim-Interval attribute from Access-Accept if local
535 'radius_acct_interim_interval' is not set
536 - allow different update intervals for each STA
537 * fixed event loop to call signal handlers only after returning from
538 the real signal handler
539 * reset sta->timeout_next after successful association to make sure
540 that the previously registered inactivity timer will not remove the
541 STA immediately (e.g., if STA deauthenticates and re-associates
542 before the timer is triggered).
543 * added new hostapd.conf variable, nas_identifier, that can be used to
544 add an optional RADIUS Attribute, NAS-Identifier, into authentication
545 and accounting messages
546 * added support for Accounting-On and Accounting-Off messages
547 * fixed accounting session handling to send Accounting-Start only once
548 per session and not to send Accounting-Stop if the session was not
550 * fixed Accounting-Stop statistics in cases where the message was
551 previously sent after the kernel entry for the STA (and/or IEEE
552 802.1X data) was removed
557 Older changes up to and including v0.1.0 are included in the ChangeLog
558 of the Host AP driver.
