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)
11 * added support for WPS USBA out-of-band mechanism with USB Flash
12 Drives (UFD) (CONFIG_WPS_UFD=y)
13 * fixed EAPOL/EAP reauthentication when using an external RADIUS
17 * added support for Wi-Fi Protected Setup (WPS)
18 (hostapd can now be configured to act as an integrated WPS Registrar
19 and provision credentials for WPS Enrollees using PIN and PBC
20 methods; external wireless Registrar can configure the AP, but
21 external WLAN Manager Registrars are not supported); WPS support can
22 be enabled by adding CONFIG_WPS=y into .config and setting the
23 runtime configuration variables in hostapd.conf (see WPS section in
24 the example configuration file); new hostapd_cli commands wps_pin and
25 wps_pbc are used to configure WPS negotiation; see README-WPS for
27 * added IEEE 802.11n HT capability configuration (ht_capab)
28 * added support for generating Country IE based on nl80211 regulatory
29 information (added if ieee80211d=1 in configuration)
30 * fixed WEP authentication (both Open System and Shared Key) with
32 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
33 * added support for using driver_test over UDP socket
34 * changed EAP-GPSK to use the IANA assigned EAP method type 51
35 * updated management frame protection to use IEEE 802.11w/D7.0
36 * fixed retransmission of EAP requests if no response is received
39 * added a new configuration option, wpa_ptk_rekey, that can be used to
40 enforce frequent PTK rekeying, e.g., to mitigate some attacks against
42 * updated OpenSSL code for EAP-FAST to use an updated version of the
43 session ticket overriding API that was included into the upstream
44 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
45 needed with that version anymore)
46 * changed channel flags configuration to read the information from
47 the driver (e.g., via driver_nl80211 when using mac80211) instead of
48 using hostapd as the source of the regulatory information (i.e.,
49 information from CRDA is now used with mac80211); this allows 5 GHz
50 channels to be used with hostapd (if allowed in the current
52 * fixed EAP-TLS message processing for the last TLS message if it is
53 large enough to require fragmentation (e.g., if a large Session
54 Ticket data is included)
55 * fixed listen interval configuration for nl80211 drivers
58 * added support for SHA-256 as X.509 certificate digest when using the
59 internal X.509/TLSv1 implementation
60 * fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer
62 * fixed internal TLSv1 implementation for abbreviated handshake (used
64 * added support for setting VLAN ID for STAs based on local MAC ACL
65 (accept_mac_file) as an alternative for RADIUS server-based
67 * updated management frame protection to use IEEE 802.11w/D6.0
68 (adds a new association ping to protect against unauthenticated
69 authenticate or (re)associate request frames dropping association)
70 * added support for using SHA256-based stronger key derivation for WPA2
72 * added new "driver wrapper" for RADIUS-only configuration
73 (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config)
74 * fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2)
75 is enabled in configuration
76 * changed EAP-FAST configuration to use separate fields for A-ID and
77 A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed
78 16-octet len binary value for better interoperability with some peer
79 implementations; eap_fast_a_id is now configured as a hex string
80 * driver_nl80211: Updated to match the current Linux mac80211 AP mode
81 configuration (wireless-testing.git and Linux kernel releases
85 * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2
86 Identity Request if identity is already known
87 * added support for EAP Sequences in EAP-FAST Phase 2
88 * added support for EAP-TNC (Trusted Network Connect)
89 (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST
90 changes needed to run two methods in sequence (IF-T) and the IF-IMV
91 and IF-TNCCS interfaces from TNCS)
92 * added support for optional cryptobinding with PEAPv0
93 * added fragmentation support for EAP-TNC
94 * added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled)
96 * added support for opportunistic key caching (OKC)
99 * fixed Reassociation Response callback processing when using internal
100 MLME (driver_{hostap,nl80211,test}.c)
101 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
102 * copy optional Proxy-State attributes into RADIUS response when acting
103 as a RADIUS authentication server
104 * fixed EAPOL state machine to handle a case in which no response is
105 received from the RADIUS authentication server; previous version
106 could have triggered a crash in some cases after a timeout
107 * fixed EAP-SIM/AKA realm processing to allow decorated usernames to
109 * added a workaround for EAP-SIM/AKA peers that include incorrect null
110 termination in the username
111 * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER
112 attribute in notification messages only when using fast
114 * fixed EAP-SIM Start response processing for fast reauthentication
116 * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST}
117 phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method
120 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
121 lengths properly to avoid potential crash caused by invalid messages
122 * added data structure for storing allocated buffers (struct wpabuf);
123 this does not affect hostapd usage, but many of the APIs changed
124 and various interfaces (e.g., EAP) is not compatible with old
126 * added support for protecting EAP-AKA/Identity messages with
127 AT_CHECKCODE (optional feature in RFC 4187)
128 * added support for protected result indication with AT_RESULT_IND for
129 EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1)
130 * added support for configuring EAP-TTLS phase 2 non-EAP methods in
131 EAP server configuration; previously all four were enabled for every
132 phase 2 user, now all four are disabled by default and need to be
133 enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP,
135 * removed old debug printing mechanism and the related 'debug'
136 parameter in the configuration file; debug verbosity is now set with
137 -d (or -dd) command line arguments
138 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
139 only shared key/password authentication is supported in this version
142 * added experimental, integrated TLSv1 server implementation with the
143 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
144 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
145 .config); this can be useful, e.g., if the target system does not
146 have a suitable TLS library and a minimal code size is required
147 * added support for EAP-FAST server method to the integrated EAP
149 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
150 draft (draft-ietf-emu-eap-gpsk-07.txt)
151 * added a new configuration parameter, rsn_pairwise, to allow different
152 pairwise cipher suites to be enabled for WPA and RSN/WPA2
153 (note: if wpa_pairwise differs from rsn_pairwise, the driver will
154 either need to support this or will have to use the WPA/RSN IEs from
155 hostapd; currently, the included madwifi and bsd driver interfaces do
156 not have support for this)
157 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
160 * added experimental IEEE 802.11r/D6.0 support
161 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
162 * updated EAP-PSK to use the IANA-allocated EAP type 47
163 * fixed EAP-PSK bit ordering of the Flags field
164 * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
165 by reading wpa_psk_file [Bug 181]
166 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
167 * fixed IPv6 connection to RADIUS accounting server
168 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
169 draft (draft-ietf-emu-eap-gpsk-04.txt)
170 * hlr_auc_gw: read GSM triplet file into memory and rotate through the
171 entries instead of only using the same three triplets every time
172 (this does not work properly with tests using multiple clients, but
173 provides bit better triplet data for testing a single client; anyway,
174 if a better quality triplets are needed, GSM-Milenage should be used
175 instead of hardcoded triplet file)
176 * fixed EAP-MSCHAPv2 server to use a space between S and M parameters
177 in Success Request [Bug 203]
178 * added support for sending EAP-AKA Notifications in error cases
179 * updated to use IEEE 802.11w/D2.0 for management frame protection
181 * RADIUS server: added support for processing duplicate messages
182 (retransmissions from RADIUS client) by replying with the previous
186 * added support for configuring and controlling multiple BSSes per
187 radio interface (bss=<ifname> in hostapd.conf); this is only
188 available with Devicescape and test driver interfaces
189 * fixed PMKSA cache update in the end of successful RSN
191 * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
192 for each STA based on RADIUS Access-Accept attributes); this requires
193 VLAN support from the kernel driver/802.11 stack and this is
194 currently only available with Devicescape and test driver interfaces
195 * driver_madwifi: fixed configuration of unencrypted modes (plaintext
196 and IEEE 802.1X without WEP)
197 * removed STAKey handshake since PeerKey handshake has replaced it in
198 IEEE 802.11ma and there are no known deployments of STAKey
199 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
200 draft (draft-ietf-emu-eap-gpsk-01.txt)
201 * added preliminary implementation of IEEE 802.11w/D1.0 (management
203 (Note: this requires driver support to work properly.)
204 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
205 * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
206 * hlr_auc_gw: added support for reading per-IMSI Milenage keys and
207 parameters from a text file to make it possible to implement proper
208 GSM/UMTS authentication server for multiple SIM/USIM cards using
210 * fixed session timeout processing with drivers that do not use
211 ieee802_11.c (e.g., madwifi)
214 * added 'hostapd_cli new_sta <addr>' command for adding a new STA into
215 hostapd (e.g., to initialize wired network authentication based on an
217 * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
218 using WPA2 even if PMKSA caching is not used
219 * added -P<pid file> argument for hostapd to write the current process
221 * added support for RADIUS Authentication Server MIB (RFC 2619)
224 * fixed nt_password_hash build [Bug 144]
225 * added PeerKey handshake implementation for IEEE 802.11e
226 direct link setup (DLS) to replace STAKey handshake
227 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
228 draft-clancy-emu-eap-shared-secret-00.txt)
229 * fixed a segmentation fault when RSN pre-authentication was completed
230 successfully [Bug 152]
233 * do not build nt_password_hash and hlr_auc_gw by default to avoid
234 requiring a TLS library for a successful build; these programs can be
235 build with 'make nt_password_hash' and 'make hlr_auc_gw'
236 * added a new configuration option, eapol_version, that can be used to
237 set EAPOL version to 1 (default is 2) to work around broken client
238 implementations that drop EAPOL frames which use version number 2
240 * added support for EAP-SAKE (no EAP method number allocated yet, so
241 this is using the same experimental type 255 as EAP-PSK)
242 * fixed EAP-MSCHAPv2 message length validation
245 * fixed stdarg use in hostapd_logger(): if both stdout and syslog
246 logging was enabled, hostapd could trigger a segmentation fault in
247 vsyslog on some CPU -- C library combinations
248 * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
249 program to make it easier to use for implementing real SS7 gateway;
250 eap_sim_db is not anymore used as a file name for GSM authentication
251 triplets; instead, it is path to UNIX domain socket that will be used
252 to communicate with the external gateway program (e.g., hlr_auc_gw)
253 * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
254 local information (GSM authentication triplets from a text file and
255 hardcoded AKA authentication data); this can be used to test EAP-SIM
257 * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
258 to make it possible to test EAP-AKA with real USIM cards (this is
259 disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
261 * driver_madwifi: added support for getting station RSN IE from
262 madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
263 broken with earlier change (r1357) in the driver
264 * changed EAP method registration to use a dynamic list of methods
265 instead of a static list generated at build time
266 * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
268 * added ap_max_inactivity configuration parameter
271 * driver_test: added better support for multiple APs and STAs by using
272 a directory with sockets that include MAC address for each device in
273 the name (test_socket=DIR:/tmp/test)
274 * added support for EAP expanded type (vendor specific EAP methods)
276 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
277 * added experimental STAKey handshake implementation for IEEE 802.11e
278 direct link setup (DLS); note: this is disabled by default in both
279 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
281 * added support for EAP methods to use callbacks to external programs
282 by buffering a pending request and processing it after the EAP method
284 * improved EAP-SIM database interface to allow external request to GSM
285 HLR/AuC without blocking hostapd process
286 * added support for using EAP-SIM pseudonyms and fast re-authentication
287 * added support for EAP-AKA in the integrated EAP authenticator
288 * added support for matching EAP identity prefixes (e.g., "1"*) in EAP
289 user database to allow EAP-SIM/AKA selection without extra roundtrip
290 for EAP-Nak negotiation
291 * added support for storing EAP user password as NtPasswordHash instead
292 of plaintext password when using MSCHAP or MSCHAPv2 for
293 authentication (hash:<16-octet hex value>); added nt_password_hash
294 tool for hashing password to generate NtPasswordHash
296 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
297 * driver_wired: fixed EAPOL sending to optionally use PAE group address
298 as the destination instead of supplicant MAC address; this is
299 disabled by default, but should be enabled with use_pae_group_addr=1
300 in configuration file if the wired interface is used by only one
301 device at the time (common switch configuration)
302 * driver_madwifi: configure driver to use TKIP countermeasures in order
303 to get correct behavior (IEEE 802.11 association failing; previously,
304 association succeeded, but hostpad forced disassociation immediately)
305 * driver_madwifi: added support for madwifi-ng
308 * added support for replacing user identity from EAP with RADIUS
309 User-Name attribute from Access-Accept message, if that is included,
310 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
311 tunneled identity into accounting messages when the RADIUS server
312 does not support better way of doing this with Class attribute)
313 * driver_madwifi: fixed EAPOL packet receive for configuration where
314 ath# is part of a bridge interface
315 * added a configuration file and log analyzer script for logwatch
316 * fixed EAPOL state machine step function to process all state
317 transitions before processing new events; this resolves a race
318 condition in which EAPOL-Start message could trigger hostapd to send
319 two EAP-Response/Identity frames to the authentication server
322 * added client CA list to the TLS certificate request in order to make
323 it easier for the client to select which certificate to use
324 * added experimental support for EAP-PSK
325 * added support for WE-19 (hostap, madwifi)
328 * fixed build without CONFIG_RSN_PREAUTH
329 * fixed FreeBSD build
332 * fixed PMKSA caching to copy User-Name and Class attributes so that
333 RADIUS accounting gets correct information
334 * start RADIUS accounting only after successful completion of WPA
335 4-Way Handshake if WPA-PSK is used
336 * fixed PMKSA caching for the case where STA (re)associates without
340 * EAP-PAX is now registered as EAP type 46
341 * fixed EAP-PAX MAC calculation
342 * fixed EAP-PAX CK and ICK key derivation
343 * renamed eap_authenticator configuration variable to eap_server to
344 better match with RFC 3748 (EAP) terminology
345 * driver_test: added support for testing hostapd with wpa_supplicant
346 by using test driver interface without any kernel drivers or network
350 * fixed RADIUS server initialization when only auth or acct server
351 is configured and the other one is left empty
352 * driver_madwifi: added support for RADIUS accounting
353 * driver_madwifi: added preliminary support for compiling against 'BSD'
354 branch of madwifi CVS tree
355 * driver_madwifi: fixed pairwise key removal to allow WPA reauth
356 without disassociation
357 * added support for reading additional certificates from PKCS#12 files
358 and adding them to the certificate chain
359 * fixed RADIUS Class attribute processing to only use Access-Accept
360 packets to update Class; previously, other RADIUS authentication
361 packets could have cleared Class attribute
362 * added support for more than one Class attribute in RADIUS packets
363 * added support for verifying certificate revocation list (CRL) when
364 using integrated EAP authenticator for EAP-TLS; new hostapd.conf
365 options 'check_crl'; CRL must be included in the ca_cert file for now
367 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
368 * added support for including network information into
369 EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
370 (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
371 * fixed a bug which caused some RSN pre-authentication cases to use
372 freed memory and potentially crash hostapd
373 * fixed private key loading for cases where passphrase is not set
374 * added support for sending TLS alerts and aborting authentication
375 when receiving a TLS alert
376 * fixed WPA2 to add PMKSA cache entry when using integrated EAP
378 * fixed PMKSA caching (EAP authentication was not skipped correctly
379 with the new state machine changes from IEEE 802.1X draft)
380 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
381 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
382 to be added to .config to include IPv6 support); for RADIUS server,
383 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
384 in RADIUS clients file can then use IPv6 format
385 * added experimental support for EAP-PAX
386 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with
387 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
389 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
392 * added support for configuring a forced PEAP version based on the
394 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
395 to terminate authentication
396 * fixed EAP identifier duplicate processing with the new IEEE 802.1X
398 * clear accounting data in the driver when starting a new accounting
400 * driver_madwifi: filter wireless events based on ifindex to allow more
401 than one network interface to be used
402 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
403 setting if the packet does not pass MIC verification (e.g., due to
404 incorrect PSK); previously, message 1/4 was not tried again if an
405 invalid message 2/4 was received
406 * fixed reconfiguration of RADIUS client retransmission timer when
407 adding a new message to the pending list; previously, timer was not
408 updated at this point and if there was a pending message with long
409 time for the next retry, the new message needed to wait that long for
413 * added support for configuring multiple allowed EAP types for Phase 2
414 authentication (EAP-PEAP, EAP-TTLS)
415 * fixed EAPOL-Start processing to trigger WPA reauthentication
416 (previously, only EAPOL authentication was done)
419 * added support for EAP-PEAP in the integrated EAP authenticator
420 * added support for EAP-GTC in the integrated EAP authenticator
421 * added support for configuring list of EAP methods for Phase 1 so that
422 the integrated EAP authenticator can, e.g., use the wildcard entry
423 for EAP-TLS and EAP-PEAP
424 * added support for EAP-TTLS in the integrated EAP authenticator
425 * added support for EAP-SIM in the integrated EAP authenticator
426 * added support for using hostapd as a RADIUS authentication server
427 with the integrated EAP authenticator taking care of EAP
428 authentication (new hostapd.conf options: radius_server_clients and
429 radius_server_auth_port); this is not included in default build; use
430 CONFIG_RADIUS_SERVER=y in .config to include
433 * removed 'daemonize' configuration file option since it has not really
434 been used at all for more than year
435 * driver_madwifi: fixed group key setup and added get_ssid method
436 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator
439 * added support for integrated EAP-TLS authentication (new hostapd.conf
440 variables: ca_cert, server_cert, private_key, private_key_passwd);
441 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
442 external RADIUS server
443 * added support for reading PKCS#12 (PFX) files (as a replacement for
444 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
446 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
447 * added support for Acct-{Input,Output}-Gigawords
448 * added support for Event-Timestamp (in RADIUS Accounting-Requests)
449 * added support for RADIUS Authentication Client MIB (RFC2618)
450 * added support for RADIUS Accounting Client MIB (RFC2620)
451 * made EAP re-authentication period configurable (eap_reauth_period)
452 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
453 * fixed EAPOL state machine to stop if STA is removed during
454 eapol_sm_step(); this fixes at least one segfault triggering bug with
455 IEEE 802.11i pre-authentication
456 * added support for multiple WPA pre-shared keys (e.g., one for each
457 client MAC address or keys shared by a group of clients);
458 new hostapd.conf field wpa_psk_file for setting path to a text file
459 containing PSKs, see hostapd.wpa_psk for an example
460 * added support for multiple driver interfaces to allow hostapd to be
461 used with other drivers
462 * added wired authenticator driver interface (driver=wired in
463 hostapd.conf, see wired.conf for example configuration)
464 * added madwifi driver interface (driver=madwifi in hostapd.conf, see
465 madwifi.conf for example configuration; Note: include files from
466 madwifi project is needed for building and a configuration file,
467 .config, needs to be created in hostapd directory with
468 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
470 * fixed an alignment issue that could cause SHA-1 to fail on some
471 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
473 * fixed RADIUS reconnection after an error in sending interim
475 * added hostapd control interface for external programs and an example
476 CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
477 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
478 'hostapd_cli sta <addr>')
479 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
480 * added support for strict GTK rekeying (wpa_strict_rekey in
482 * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
483 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
485 * added Prism54 driver interface (driver=prism54 in hostapd.conf;
486 note: .config needs to be created in hostapd directory with
487 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
489 * dual-licensed hostapd (GPLv2 and BSD licenses)
490 * fixed RADIUS accounting to generate a new session id for cases where
491 a station reassociates without first being complete deauthenticated
492 * fixed STA disassociation handler to mark next timeout state to
493 deauthenticate the station, i.e., skip long wait for inactivity poll
494 and extra disassociation, if the STA disassociates without
496 * added integrated EAP authenticator that can be used instead of
497 external RADIUS authentication server; currently, only EAP-MD5 is
498 supported, so this cannot yet be used for key distribution; the EAP
499 method interface is generic, though, so adding new EAP methods should
500 be straightforward; new hostapd.conf variables: 'eap_authenticator'
501 and 'eap_user_file'; this obsoletes "minimal authentication server"
502 ('minimal_eap' in hostapd.conf) which is now removed
503 * added support for FreeBSD and driver interface for the BSD net80211
504 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
505 .config); please note that some of the required kernel mods have not
508 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
509 * fixed some accounting cases where Accounting-Start was sent when
510 IEEE 802.1X port was being deauthorized
513 * modified RADIUS client to re-connect the socket in case of certain
514 error codes that are generated when a network interface state is
515 changes (e.g., when IP address changes or the interface is set UP)
516 * fixed couple of cases where EAPOL state for a station was freed
517 twice causing a segfault for hostapd
518 * fixed couple of bugs in processing WPA deauthentication (freed data
522 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
523 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
524 cases where STAs dropped multicast frames as replay attacks
525 * added support for copying RADIUS Attribute 'Class' from
526 authentication messages into accounting messages
527 * send canned EAP failure if RADIUS server sends Access-Reject without
528 EAP message (previously, Supplicant was not notified in this case)
529 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
530 not start EAPOL state machines if the STA selected to use WPA-PSK)
533 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
534 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
535 (i.e., IEEE 802.11i/D3.0)
536 - supports WPA-only, RSN-only, and mixed WPA/RSN mode
537 - both WPA-PSK and WPA-RADIUS/EAP are supported
538 - PMKSA caching and pre-authentication
539 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
540 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
541 rsn_preauth, rsn_preauth_interfaces
542 * fixed interim accounting to remove any pending accounting messages
543 to the STA before sending a new one
546 * added support for Acct-Interim-Interval:
547 - draft-ietf-radius-acct-interim-01.txt
548 - use Acct-Interim-Interval attribute from Access-Accept if local
549 'radius_acct_interim_interval' is not set
550 - allow different update intervals for each STA
551 * fixed event loop to call signal handlers only after returning from
552 the real signal handler
553 * reset sta->timeout_next after successful association to make sure
554 that the previously registered inactivity timer will not remove the
555 STA immediately (e.g., if STA deauthenticates and re-associates
556 before the timer is triggered).
557 * added new hostapd.conf variable, nas_identifier, that can be used to
558 add an optional RADIUS Attribute, NAS-Identifier, into authentication
559 and accounting messages
560 * added support for Accounting-On and Accounting-Off messages
561 * fixed accounting session handling to send Accounting-Start only once
562 per session and not to send Accounting-Stop if the session was not
564 * fixed Accounting-Stop statistics in cases where the message was
565 previously sent after the kernel entry for the STA (and/or IEEE
566 802.1X data) was removed
571 Older changes up to and including v0.1.0 are included in the ChangeLog
572 of the Host AP driver.
