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
9 * driver_nl80211: fixed STA accounting data collection (TX/RX bytes
10 reported correctly; TX/RX packets not yet available from kernel)
13 * added support for Wi-Fi Protected Setup (WPS)
14 (hostapd can now be configured to act as an integrated WPS Registrar
15 and provision credentials for WPS Enrollees using PIN and PBC
16 methods; external wireless Registrar can configure the AP, but
17 external WLAN Manager Registrars are not supported); WPS support can
18 be enabled by adding CONFIG_WPS=y into .config and setting the
19 runtime configuration variables in hostapd.conf (see WPS section in
20 the example configuration file); new hostapd_cli commands wps_pin and
21 wps_pbc are used to configure WPS negotiation; see README-WPS for
23 * added IEEE 802.11n HT capability configuration (ht_capab)
24 * added support for generating Country IE based on nl80211 regulatory
25 information (added if ieee80211d=1 in configuration)
26 * fixed WEP authentication (both Open System and Shared Key) with
28 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
29 * added support for using driver_test over UDP socket
30 * changed EAP-GPSK to use the IANA assigned EAP method type 51
31 * updated management frame protection to use IEEE 802.11w/D7.0
32 * fixed retransmission of EAP requests if no response is received
35 * added a new configuration option, wpa_ptk_rekey, that can be used to
36 enforce frequent PTK rekeying, e.g., to mitigate some attacks against
38 * updated OpenSSL code for EAP-FAST to use an updated version of the
39 session ticket overriding API that was included into the upstream
40 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
41 needed with that version anymore)
42 * changed channel flags configuration to read the information from
43 the driver (e.g., via driver_nl80211 when using mac80211) instead of
44 using hostapd as the source of the regulatory information (i.e.,
45 information from CRDA is now used with mac80211); this allows 5 GHz
46 channels to be used with hostapd (if allowed in the current
48 * fixed EAP-TLS message processing for the last TLS message if it is
49 large enough to require fragmentation (e.g., if a large Session
50 Ticket data is included)
51 * fixed listen interval configuration for nl80211 drivers
54 * added support for SHA-256 as X.509 certificate digest when using the
55 internal X.509/TLSv1 implementation
56 * fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer
58 * fixed internal TLSv1 implementation for abbreviated handshake (used
60 * added support for setting VLAN ID for STAs based on local MAC ACL
61 (accept_mac_file) as an alternative for RADIUS server-based
63 * updated management frame protection to use IEEE 802.11w/D6.0
64 (adds a new association ping to protect against unauthenticated
65 authenticate or (re)associate request frames dropping association)
66 * added support for using SHA256-based stronger key derivation for WPA2
68 * added new "driver wrapper" for RADIUS-only configuration
69 (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config)
70 * fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2)
71 is enabled in configuration
72 * changed EAP-FAST configuration to use separate fields for A-ID and
73 A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed
74 16-octet len binary value for better interoperability with some peer
75 implementations; eap_fast_a_id is now configured as a hex string
76 * driver_nl80211: Updated to match the current Linux mac80211 AP mode
77 configuration (wireless-testing.git and Linux kernel releases
81 * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2
82 Identity Request if identity is already known
83 * added support for EAP Sequences in EAP-FAST Phase 2
84 * added support for EAP-TNC (Trusted Network Connect)
85 (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST
86 changes needed to run two methods in sequence (IF-T) and the IF-IMV
87 and IF-TNCCS interfaces from TNCS)
88 * added support for optional cryptobinding with PEAPv0
89 * added fragmentation support for EAP-TNC
90 * added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled)
92 * added support for opportunistic key caching (OKC)
95 * fixed Reassociation Response callback processing when using internal
96 MLME (driver_{hostap,nl80211,test}.c)
97 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
98 * copy optional Proxy-State attributes into RADIUS response when acting
99 as a RADIUS authentication server
100 * fixed EAPOL state machine to handle a case in which no response is
101 received from the RADIUS authentication server; previous version
102 could have triggered a crash in some cases after a timeout
103 * fixed EAP-SIM/AKA realm processing to allow decorated usernames to
105 * added a workaround for EAP-SIM/AKA peers that include incorrect null
106 termination in the username
107 * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER
108 attribute in notification messages only when using fast
110 * fixed EAP-SIM Start response processing for fast reauthentication
112 * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST}
113 phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method
116 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
117 lengths properly to avoid potential crash caused by invalid messages
118 * added data structure for storing allocated buffers (struct wpabuf);
119 this does not affect hostapd usage, but many of the APIs changed
120 and various interfaces (e.g., EAP) is not compatible with old
122 * added support for protecting EAP-AKA/Identity messages with
123 AT_CHECKCODE (optional feature in RFC 4187)
124 * added support for protected result indication with AT_RESULT_IND for
125 EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1)
126 * added support for configuring EAP-TTLS phase 2 non-EAP methods in
127 EAP server configuration; previously all four were enabled for every
128 phase 2 user, now all four are disabled by default and need to be
129 enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP,
131 * removed old debug printing mechanism and the related 'debug'
132 parameter in the configuration file; debug verbosity is now set with
133 -d (or -dd) command line arguments
134 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
135 only shared key/password authentication is supported in this version
138 * added experimental, integrated TLSv1 server implementation with the
139 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
140 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
141 .config); this can be useful, e.g., if the target system does not
142 have a suitable TLS library and a minimal code size is required
143 * added support for EAP-FAST server method to the integrated EAP
145 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
146 draft (draft-ietf-emu-eap-gpsk-07.txt)
147 * added a new configuration parameter, rsn_pairwise, to allow different
148 pairwise cipher suites to be enabled for WPA and RSN/WPA2
149 (note: if wpa_pairwise differs from rsn_pairwise, the driver will
150 either need to support this or will have to use the WPA/RSN IEs from
151 hostapd; currently, the included madwifi and bsd driver interfaces do
152 not have support for this)
153 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
156 * added experimental IEEE 802.11r/D6.0 support
157 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
158 * updated EAP-PSK to use the IANA-allocated EAP type 47
159 * fixed EAP-PSK bit ordering of the Flags field
160 * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
161 by reading wpa_psk_file [Bug 181]
162 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
163 * fixed IPv6 connection to RADIUS accounting server
164 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
165 draft (draft-ietf-emu-eap-gpsk-04.txt)
166 * hlr_auc_gw: read GSM triplet file into memory and rotate through the
167 entries instead of only using the same three triplets every time
168 (this does not work properly with tests using multiple clients, but
169 provides bit better triplet data for testing a single client; anyway,
170 if a better quality triplets are needed, GSM-Milenage should be used
171 instead of hardcoded triplet file)
172 * fixed EAP-MSCHAPv2 server to use a space between S and M parameters
173 in Success Request [Bug 203]
174 * added support for sending EAP-AKA Notifications in error cases
175 * updated to use IEEE 802.11w/D2.0 for management frame protection
177 * RADIUS server: added support for processing duplicate messages
178 (retransmissions from RADIUS client) by replying with the previous
182 * added support for configuring and controlling multiple BSSes per
183 radio interface (bss=<ifname> in hostapd.conf); this is only
184 available with Devicescape and test driver interfaces
185 * fixed PMKSA cache update in the end of successful RSN
187 * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
188 for each STA based on RADIUS Access-Accept attributes); this requires
189 VLAN support from the kernel driver/802.11 stack and this is
190 currently only available with Devicescape and test driver interfaces
191 * driver_madwifi: fixed configuration of unencrypted modes (plaintext
192 and IEEE 802.1X without WEP)
193 * removed STAKey handshake since PeerKey handshake has replaced it in
194 IEEE 802.11ma and there are no known deployments of STAKey
195 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
196 draft (draft-ietf-emu-eap-gpsk-01.txt)
197 * added preliminary implementation of IEEE 802.11w/D1.0 (management
199 (Note: this requires driver support to work properly.)
200 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
201 * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
202 * hlr_auc_gw: added support for reading per-IMSI Milenage keys and
203 parameters from a text file to make it possible to implement proper
204 GSM/UMTS authentication server for multiple SIM/USIM cards using
206 * fixed session timeout processing with drivers that do not use
207 ieee802_11.c (e.g., madwifi)
210 * added 'hostapd_cli new_sta <addr>' command for adding a new STA into
211 hostapd (e.g., to initialize wired network authentication based on an
213 * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
214 using WPA2 even if PMKSA caching is not used
215 * added -P<pid file> argument for hostapd to write the current process
217 * added support for RADIUS Authentication Server MIB (RFC 2619)
220 * fixed nt_password_hash build [Bug 144]
221 * added PeerKey handshake implementation for IEEE 802.11e
222 direct link setup (DLS) to replace STAKey handshake
223 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
224 draft-clancy-emu-eap-shared-secret-00.txt)
225 * fixed a segmentation fault when RSN pre-authentication was completed
226 successfully [Bug 152]
229 * do not build nt_password_hash and hlr_auc_gw by default to avoid
230 requiring a TLS library for a successful build; these programs can be
231 build with 'make nt_password_hash' and 'make hlr_auc_gw'
232 * added a new configuration option, eapol_version, that can be used to
233 set EAPOL version to 1 (default is 2) to work around broken client
234 implementations that drop EAPOL frames which use version number 2
236 * added support for EAP-SAKE (no EAP method number allocated yet, so
237 this is using the same experimental type 255 as EAP-PSK)
238 * fixed EAP-MSCHAPv2 message length validation
241 * fixed stdarg use in hostapd_logger(): if both stdout and syslog
242 logging was enabled, hostapd could trigger a segmentation fault in
243 vsyslog on some CPU -- C library combinations
244 * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
245 program to make it easier to use for implementing real SS7 gateway;
246 eap_sim_db is not anymore used as a file name for GSM authentication
247 triplets; instead, it is path to UNIX domain socket that will be used
248 to communicate with the external gateway program (e.g., hlr_auc_gw)
249 * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
250 local information (GSM authentication triplets from a text file and
251 hardcoded AKA authentication data); this can be used to test EAP-SIM
253 * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
254 to make it possible to test EAP-AKA with real USIM cards (this is
255 disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
257 * driver_madwifi: added support for getting station RSN IE from
258 madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
259 broken with earlier change (r1357) in the driver
260 * changed EAP method registration to use a dynamic list of methods
261 instead of a static list generated at build time
262 * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
264 * added ap_max_inactivity configuration parameter
267 * driver_test: added better support for multiple APs and STAs by using
268 a directory with sockets that include MAC address for each device in
269 the name (test_socket=DIR:/tmp/test)
270 * added support for EAP expanded type (vendor specific EAP methods)
272 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
273 * added experimental STAKey handshake implementation for IEEE 802.11e
274 direct link setup (DLS); note: this is disabled by default in both
275 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
277 * added support for EAP methods to use callbacks to external programs
278 by buffering a pending request and processing it after the EAP method
280 * improved EAP-SIM database interface to allow external request to GSM
281 HLR/AuC without blocking hostapd process
282 * added support for using EAP-SIM pseudonyms and fast re-authentication
283 * added support for EAP-AKA in the integrated EAP authenticator
284 * added support for matching EAP identity prefixes (e.g., "1"*) in EAP
285 user database to allow EAP-SIM/AKA selection without extra roundtrip
286 for EAP-Nak negotiation
287 * added support for storing EAP user password as NtPasswordHash instead
288 of plaintext password when using MSCHAP or MSCHAPv2 for
289 authentication (hash:<16-octet hex value>); added nt_password_hash
290 tool for hashing password to generate NtPasswordHash
292 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
293 * driver_wired: fixed EAPOL sending to optionally use PAE group address
294 as the destination instead of supplicant MAC address; this is
295 disabled by default, but should be enabled with use_pae_group_addr=1
296 in configuration file if the wired interface is used by only one
297 device at the time (common switch configuration)
298 * driver_madwifi: configure driver to use TKIP countermeasures in order
299 to get correct behavior (IEEE 802.11 association failing; previously,
300 association succeeded, but hostpad forced disassociation immediately)
301 * driver_madwifi: added support for madwifi-ng
304 * added support for replacing user identity from EAP with RADIUS
305 User-Name attribute from Access-Accept message, if that is included,
306 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
307 tunneled identity into accounting messages when the RADIUS server
308 does not support better way of doing this with Class attribute)
309 * driver_madwifi: fixed EAPOL packet receive for configuration where
310 ath# is part of a bridge interface
311 * added a configuration file and log analyzer script for logwatch
312 * fixed EAPOL state machine step function to process all state
313 transitions before processing new events; this resolves a race
314 condition in which EAPOL-Start message could trigger hostapd to send
315 two EAP-Response/Identity frames to the authentication server
318 * added client CA list to the TLS certificate request in order to make
319 it easier for the client to select which certificate to use
320 * added experimental support for EAP-PSK
321 * added support for WE-19 (hostap, madwifi)
324 * fixed build without CONFIG_RSN_PREAUTH
325 * fixed FreeBSD build
328 * fixed PMKSA caching to copy User-Name and Class attributes so that
329 RADIUS accounting gets correct information
330 * start RADIUS accounting only after successful completion of WPA
331 4-Way Handshake if WPA-PSK is used
332 * fixed PMKSA caching for the case where STA (re)associates without
336 * EAP-PAX is now registered as EAP type 46
337 * fixed EAP-PAX MAC calculation
338 * fixed EAP-PAX CK and ICK key derivation
339 * renamed eap_authenticator configuration variable to eap_server to
340 better match with RFC 3748 (EAP) terminology
341 * driver_test: added support for testing hostapd with wpa_supplicant
342 by using test driver interface without any kernel drivers or network
346 * fixed RADIUS server initialization when only auth or acct server
347 is configured and the other one is left empty
348 * driver_madwifi: added support for RADIUS accounting
349 * driver_madwifi: added preliminary support for compiling against 'BSD'
350 branch of madwifi CVS tree
351 * driver_madwifi: fixed pairwise key removal to allow WPA reauth
352 without disassociation
353 * added support for reading additional certificates from PKCS#12 files
354 and adding them to the certificate chain
355 * fixed RADIUS Class attribute processing to only use Access-Accept
356 packets to update Class; previously, other RADIUS authentication
357 packets could have cleared Class attribute
358 * added support for more than one Class attribute in RADIUS packets
359 * added support for verifying certificate revocation list (CRL) when
360 using integrated EAP authenticator for EAP-TLS; new hostapd.conf
361 options 'check_crl'; CRL must be included in the ca_cert file for now
363 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
364 * added support for including network information into
365 EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
366 (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
367 * fixed a bug which caused some RSN pre-authentication cases to use
368 freed memory and potentially crash hostapd
369 * fixed private key loading for cases where passphrase is not set
370 * added support for sending TLS alerts and aborting authentication
371 when receiving a TLS alert
372 * fixed WPA2 to add PMKSA cache entry when using integrated EAP
374 * fixed PMKSA caching (EAP authentication was not skipped correctly
375 with the new state machine changes from IEEE 802.1X draft)
376 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
377 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
378 to be added to .config to include IPv6 support); for RADIUS server,
379 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
380 in RADIUS clients file can then use IPv6 format
381 * added experimental support for EAP-PAX
382 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with
383 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
385 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
388 * added support for configuring a forced PEAP version based on the
390 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
391 to terminate authentication
392 * fixed EAP identifier duplicate processing with the new IEEE 802.1X
394 * clear accounting data in the driver when starting a new accounting
396 * driver_madwifi: filter wireless events based on ifindex to allow more
397 than one network interface to be used
398 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
399 setting if the packet does not pass MIC verification (e.g., due to
400 incorrect PSK); previously, message 1/4 was not tried again if an
401 invalid message 2/4 was received
402 * fixed reconfiguration of RADIUS client retransmission timer when
403 adding a new message to the pending list; previously, timer was not
404 updated at this point and if there was a pending message with long
405 time for the next retry, the new message needed to wait that long for
409 * added support for configuring multiple allowed EAP types for Phase 2
410 authentication (EAP-PEAP, EAP-TTLS)
411 * fixed EAPOL-Start processing to trigger WPA reauthentication
412 (previously, only EAPOL authentication was done)
415 * added support for EAP-PEAP in the integrated EAP authenticator
416 * added support for EAP-GTC in the integrated EAP authenticator
417 * added support for configuring list of EAP methods for Phase 1 so that
418 the integrated EAP authenticator can, e.g., use the wildcard entry
419 for EAP-TLS and EAP-PEAP
420 * added support for EAP-TTLS in the integrated EAP authenticator
421 * added support for EAP-SIM in the integrated EAP authenticator
422 * added support for using hostapd as a RADIUS authentication server
423 with the integrated EAP authenticator taking care of EAP
424 authentication (new hostapd.conf options: radius_server_clients and
425 radius_server_auth_port); this is not included in default build; use
426 CONFIG_RADIUS_SERVER=y in .config to include
429 * removed 'daemonize' configuration file option since it has not really
430 been used at all for more than year
431 * driver_madwifi: fixed group key setup and added get_ssid method
432 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator
435 * added support for integrated EAP-TLS authentication (new hostapd.conf
436 variables: ca_cert, server_cert, private_key, private_key_passwd);
437 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
438 external RADIUS server
439 * added support for reading PKCS#12 (PFX) files (as a replacement for
440 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
442 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
443 * added support for Acct-{Input,Output}-Gigawords
444 * added support for Event-Timestamp (in RADIUS Accounting-Requests)
445 * added support for RADIUS Authentication Client MIB (RFC2618)
446 * added support for RADIUS Accounting Client MIB (RFC2620)
447 * made EAP re-authentication period configurable (eap_reauth_period)
448 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
449 * fixed EAPOL state machine to stop if STA is removed during
450 eapol_sm_step(); this fixes at least one segfault triggering bug with
451 IEEE 802.11i pre-authentication
452 * added support for multiple WPA pre-shared keys (e.g., one for each
453 client MAC address or keys shared by a group of clients);
454 new hostapd.conf field wpa_psk_file for setting path to a text file
455 containing PSKs, see hostapd.wpa_psk for an example
456 * added support for multiple driver interfaces to allow hostapd to be
457 used with other drivers
458 * added wired authenticator driver interface (driver=wired in
459 hostapd.conf, see wired.conf for example configuration)
460 * added madwifi driver interface (driver=madwifi in hostapd.conf, see
461 madwifi.conf for example configuration; Note: include files from
462 madwifi project is needed for building and a configuration file,
463 .config, needs to be created in hostapd directory with
464 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
466 * fixed an alignment issue that could cause SHA-1 to fail on some
467 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
469 * fixed RADIUS reconnection after an error in sending interim
471 * added hostapd control interface for external programs and an example
472 CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
473 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
474 'hostapd_cli sta <addr>')
475 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
476 * added support for strict GTK rekeying (wpa_strict_rekey in
478 * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
479 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
481 * added Prism54 driver interface (driver=prism54 in hostapd.conf;
482 note: .config needs to be created in hostapd directory with
483 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
485 * dual-licensed hostapd (GPLv2 and BSD licenses)
486 * fixed RADIUS accounting to generate a new session id for cases where
487 a station reassociates without first being complete deauthenticated
488 * fixed STA disassociation handler to mark next timeout state to
489 deauthenticate the station, i.e., skip long wait for inactivity poll
490 and extra disassociation, if the STA disassociates without
492 * added integrated EAP authenticator that can be used instead of
493 external RADIUS authentication server; currently, only EAP-MD5 is
494 supported, so this cannot yet be used for key distribution; the EAP
495 method interface is generic, though, so adding new EAP methods should
496 be straightforward; new hostapd.conf variables: 'eap_authenticator'
497 and 'eap_user_file'; this obsoletes "minimal authentication server"
498 ('minimal_eap' in hostapd.conf) which is now removed
499 * added support for FreeBSD and driver interface for the BSD net80211
500 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
501 .config); please note that some of the required kernel mods have not
504 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
505 * fixed some accounting cases where Accounting-Start was sent when
506 IEEE 802.1X port was being deauthorized
509 * modified RADIUS client to re-connect the socket in case of certain
510 error codes that are generated when a network interface state is
511 changes (e.g., when IP address changes or the interface is set UP)
512 * fixed couple of cases where EAPOL state for a station was freed
513 twice causing a segfault for hostapd
514 * fixed couple of bugs in processing WPA deauthentication (freed data
518 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
519 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
520 cases where STAs dropped multicast frames as replay attacks
521 * added support for copying RADIUS Attribute 'Class' from
522 authentication messages into accounting messages
523 * send canned EAP failure if RADIUS server sends Access-Reject without
524 EAP message (previously, Supplicant was not notified in this case)
525 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
526 not start EAPOL state machines if the STA selected to use WPA-PSK)
529 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
530 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
531 (i.e., IEEE 802.11i/D3.0)
532 - supports WPA-only, RSN-only, and mixed WPA/RSN mode
533 - both WPA-PSK and WPA-RADIUS/EAP are supported
534 - PMKSA caching and pre-authentication
535 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
536 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
537 rsn_preauth, rsn_preauth_interfaces
538 * fixed interim accounting to remove any pending accounting messages
539 to the STA before sending a new one
542 * added support for Acct-Interim-Interval:
543 - draft-ietf-radius-acct-interim-01.txt
544 - use Acct-Interim-Interval attribute from Access-Accept if local
545 'radius_acct_interim_interval' is not set
546 - allow different update intervals for each STA
547 * fixed event loop to call signal handlers only after returning from
548 the real signal handler
549 * reset sta->timeout_next after successful association to make sure
550 that the previously registered inactivity timer will not remove the
551 STA immediately (e.g., if STA deauthenticates and re-associates
552 before the timer is triggered).
553 * added new hostapd.conf variable, nas_identifier, that can be used to
554 add an optional RADIUS Attribute, NAS-Identifier, into authentication
555 and accounting messages
556 * added support for Accounting-On and Accounting-Off messages
557 * fixed accounting session handling to send Accounting-Start only once
558 per session and not to send Accounting-Stop if the session was not
560 * fixed Accounting-Stop statistics in cases where the message was
561 previously sent after the kernel entry for the STA (and/or IEEE
562 802.1X data) was removed
567 Older changes up to and including v0.1.0 are included in the ChangeLog
568 of the Host AP driver.
