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
15 * fixed TNC with EAP-TTLS
16 * fixed IEEE 802.11r key derivation function to match with the standard
17 (note: this breaks interoperability with previous version) [Bug 303]
18 * fixed SHA-256 based key derivation function to match with the
19 standard when using CCMP (for IEEE 802.11r and IEEE 802.11w)
20 (note: this breaks interoperability with previous version) [Bug 307]
23 * added support for Wi-Fi Protected Setup (WPS)
24 (hostapd can now be configured to act as an integrated WPS Registrar
25 and provision credentials for WPS Enrollees using PIN and PBC
26 methods; external wireless Registrar can configure the AP, but
27 external WLAN Manager Registrars are not supported); WPS support can
28 be enabled by adding CONFIG_WPS=y into .config and setting the
29 runtime configuration variables in hostapd.conf (see WPS section in
30 the example configuration file); new hostapd_cli commands wps_pin and
31 wps_pbc are used to configure WPS negotiation; see README-WPS for
33 * added IEEE 802.11n HT capability configuration (ht_capab)
34 * added support for generating Country IE based on nl80211 regulatory
35 information (added if ieee80211d=1 in configuration)

38 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
39 * added support for using driver_test over UDP socket
40 * changed EAP-GPSK to use the IANA assigned EAP method type 51
41 * updated management frame protection to use IEEE 802.11w/D7.0
42 * fixed retransmission of EAP requests if no response is received
45 * added a new configuration option, wpa_ptk_rekey, that can be used to
46 enforce frequent PTK rekeying, e.g., to mitigate some attacks against
48 * updated OpenSSL code for EAP-FAST to use an updated version of the
49 session ticket overriding API that was included into the upstream
50 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
51 needed with that version anymore)
52 * changed channel flags configuration to read the information from
53 the driver (e.g., via driver_nl80211 when using mac80211) instead of
54 using hostapd as the source of the regulatory information (i.e.,
55 information from CRDA is now used with mac80211); this allows 5 GHz
56 channels to be used with hostapd (if allowed in the current
58 * fixed EAP-TLS message processing for the last TLS message if it is
59 large enough to require fragmentation (e.g., if a large Session
60 Ticket data is included)
61 * fixed listen interval configuration for nl80211 drivers
64 * added support for SHA-256 as X.509 certificate digest when using the
65 internal X.509/TLSv1 implementation
66 * fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer
68 * fixed internal TLSv1 implementation for abbreviated handshake (used
70 * added support for setting VLAN ID for STAs based on local MAC ACL
71 (accept_mac_file) as an alternative for RADIUS server-based
73 * updated management frame protection to use IEEE 802.11w/D6.0
74 (adds a new association ping to protect against unauthenticated
75 authenticate or (re)associate request frames dropping association)
76 * added support for using SHA256-based stronger key derivation for WPA2
78 * added new "driver wrapper" for RADIUS-only configuration
79 (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config)
80 * fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2)
81 is enabled in configuration
82 * changed EAP-FAST configuration to use separate fields for A-ID and
83 A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed
84 16-octet len binary value for better interoperability with some peer
85 implementations; eap_fast_a_id is now configured as a hex string
86 * driver_nl80211: Updated to match the current Linux mac80211 AP mode
87 configuration (wireless-testing.git and Linux kernel releases
91 * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2
92 Identity Request if identity is already known
93 * added support for EAP Sequences in EAP-FAST Phase 2
94 * added support for EAP-TNC (Trusted Network Connect)
95 (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST
96 changes needed to run two methods in sequence (IF-T) and the IF-IMV
97 and IF-TNCCS interfaces from TNCS)
98 * added support for optional cryptobinding with PEAPv0
99 * added fragmentation support for EAP-TNC
100 * added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled)
102 * added support for opportunistic key caching (OKC)
105 * fixed Reassociation Response callback processing when using internal
106 MLME (driver_{hostap,nl80211,test}.c)
107 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
108 * copy optional Proxy-State attributes into RADIUS response when acting
109 as a RADIUS authentication server
110 * fixed EAPOL state machine to handle a case in which no response is
111 received from the RADIUS authentication server; previous version
112 could have triggered a crash in some cases after a timeout
113 * fixed EAP-SIM/AKA realm processing to allow decorated usernames to
115 * added a workaround for EAP-SIM/AKA peers that include incorrect null
116 termination in the username
117 * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER
118 attribute in notification messages only when using fast
120 * fixed EAP-SIM Start response processing for fast reauthentication
122 * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST}
123 phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method
126 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
127 lengths properly to avoid potential crash caused by invalid messages
128 * added data structure for storing allocated buffers (struct wpabuf);
129 this does not affect hostapd usage, but many of the APIs changed
130 and various interfaces (e.g., EAP) is not compatible with old
132 * added support for protecting EAP-AKA/Identity messages with
133 AT_CHECKCODE (optional feature in RFC 4187)
134 * added support for protected result indication with AT_RESULT_IND for
135 EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1)
136 * added support for configuring EAP-TTLS phase 2 non-EAP methods in
137 EAP server configuration; previously all four were enabled for every
138 phase 2 user, now all four are disabled by default and need to be
139 enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP,
141 * removed old debug printing mechanism and the related 'debug'
142 parameter in the configuration file; debug verbosity is now set with
143 -d (or -dd) command line arguments
144 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
145 only shared key/password authentication is supported in this version
148 * added experimental, integrated TLSv1 server implementation with the
149 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
150 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
151 .config); this can be useful, e.g., if the target system does not
152 have a suitable TLS library and a minimal code size is required
153 * added support for EAP-FAST server method to the integrated EAP
155 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
156 draft (draft-ietf-emu-eap-gpsk-07.txt)
157 * added a new configuration parameter, rsn_pairwise, to allow different
158 pairwise cipher suites to be enabled for WPA and RSN/WPA2
159 (note: if wpa_pairwise differs from rsn_pairwise, the driver will
160 either need to support this or will have to use the WPA/RSN IEs from
161 hostapd; currently, the included madwifi and bsd driver interfaces do
162 not have support for this)
163 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
166 * added experimental IEEE 802.11r/D6.0 support
167 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
168 * updated EAP-PSK to use the IANA-allocated EAP type 47
169 * fixed EAP-PSK bit ordering of the Flags field
170 * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
171 by reading wpa_psk_file [Bug 181]
172 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
173 * fixed IPv6 connection to RADIUS accounting server
174 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
175 draft (draft-ietf-emu-eap-gpsk-04.txt)
176 * hlr_auc_gw: read GSM triplet file into memory and rotate through the
177 entries instead of only using the same three triplets every time
178 (this does not work properly with tests using multiple clients, but
179 provides bit better triplet data for testing a single client; anyway,
180 if a better quality triplets are needed, GSM-Milenage should be used
181 instead of hardcoded triplet file)
182 * fixed EAP-MSCHAPv2 server to use a space between S and M parameters
183 in Success Request [Bug 203]
184 * added support for sending EAP-AKA Notifications in error cases
185 * updated to use IEEE 802.11w/D2.0 for management frame protection
187 * RADIUS server: added support for processing duplicate messages
188 (retransmissions from RADIUS client) by replying with the previous
192 * added support for configuring and controlling multiple BSSes per
193 radio interface (bss=<ifname> in hostapd.conf); this is only
194 available with Devicescape and test driver interfaces
195 * fixed PMKSA cache update in the end of successful RSN
197 * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
198 for each STA based on RADIUS Access-Accept attributes); this requires
199 VLAN support from the kernel driver/802.11 stack and this is
200 currently only available with Devicescape and test driver interfaces
201 * driver_madwifi: fixed configuration of unencrypted modes (plaintext
202 and IEEE 802.1X without WEP)
203 * removed STAKey handshake since PeerKey handshake has replaced it in
204 IEEE 802.11ma and there are no known deployments of STAKey
205 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
206 draft (draft-ietf-emu-eap-gpsk-01.txt)
207 * added preliminary implementation of IEEE 802.11w/D1.0 (management
209 (Note: this requires driver support to work properly.)
210 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
211 * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
212 * hlr_auc_gw: added support for reading per-IMSI Milenage keys and
213 parameters from a text file to make it possible to implement proper
214 GSM/UMTS authentication server for multiple SIM/USIM cards using
216 * fixed session timeout processing with drivers that do not use
217 ieee802_11.c (e.g., madwifi)
220 * added 'hostapd_cli new_sta <addr>' command for adding a new STA into
221 hostapd (e.g., to initialize wired network authentication based on an
223 * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
224 using WPA2 even if PMKSA caching is not used
225 * added -P<pid file> argument for hostapd to write the current process
227 * added support for RADIUS Authentication Server MIB (RFC 2619)
230 * fixed nt_password_hash build [Bug 144]
231 * added PeerKey handshake implementation for IEEE 802.11e
232 direct link setup (DLS) to replace STAKey handshake
233 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
234 draft-clancy-emu-eap-shared-secret-00.txt)
235 * fixed a segmentation fault when RSN pre-authentication was completed
236 successfully [Bug 152]
239 * do not build nt_password_hash and hlr_auc_gw by default to avoid
240 requiring a TLS library for a successful build; these programs can be
241 build with 'make nt_password_hash' and 'make hlr_auc_gw'
242 * added a new configuration option, eapol_version, that can be used to
243 set EAPOL version to 1 (default is 2) to work around broken client
244 implementations that drop EAPOL frames which use version number 2
246 * added support for EAP-SAKE (no EAP method number allocated yet, so
247 this is using the same experimental type 255 as EAP-PSK)
248 * fixed EAP-MSCHAPv2 message length validation
251 * fixed stdarg use in hostapd_logger(): if both stdout and syslog
252 logging was enabled, hostapd could trigger a segmentation fault in
253 vsyslog on some CPU -- C library combinations
254 * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
255 program to make it easier to use for implementing real SS7 gateway;
256 eap_sim_db is not anymore used as a file name for GSM authentication
257 triplets; instead, it is path to UNIX domain socket that will be used
258 to communicate with the external gateway program (e.g., hlr_auc_gw)
259 * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
260 local information (GSM authentication triplets from a text file and
261 hardcoded AKA authentication data); this can be used to test EAP-SIM
263 * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
264 to make it possible to test EAP-AKA with real USIM cards (this is
265 disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
267 * driver_madwifi: added support for getting station RSN IE from
268 madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
269 broken with earlier change (r1357) in the driver
270 * changed EAP method registration to use a dynamic list of methods
271 instead of a static list generated at build time
272 * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
274 * added ap_max_inactivity configuration parameter
277 * driver_test: added better support for multiple APs and STAs by using
278 a directory with sockets that include MAC address for each device in
279 the name (test_socket=DIR:/tmp/test)
280 * added support for EAP expanded type (vendor specific EAP methods)
282 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
283 * added experimental STAKey handshake implementation for IEEE 802.11e
284 direct link setup (DLS); note: this is disabled by default in both
285 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
287 * added support for EAP methods to use callbacks to external programs
288 by buffering a pending request and processing it after the EAP method
290 * improved EAP-SIM database interface to allow external request to GSM
291 HLR/AuC without blocking hostapd process
292 * added support for using EAP-SIM pseudonyms and fast re-authentication
293 * added support for EAP-AKA in the integrated EAP authenticator
294 * added support for matching EAP identity prefixes (e.g., "1"*) in EAP
295 user database to allow EAP-SIM/AKA selection without extra roundtrip
296 for EAP-Nak negotiation
297 * added support for storing EAP user password as NtPasswordHash instead
298 of plaintext password when using MSCHAP or MSCHAPv2 for
299 authentication (hash:<16-octet hex value>); added nt_password_hash
300 tool for hashing password to generate NtPasswordHash
302 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
303 * driver_wired: fixed EAPOL sending to optionally use PAE group address
304 as the destination instead of supplicant MAC address; this is
305 disabled by default, but should be enabled with use_pae_group_addr=1
306 in configuration file if the wired interface is used by only one
307 device at the time (common switch configuration)
308 * driver_madwifi: configure driver to use TKIP countermeasures in order
309 to get correct behavior (IEEE 802.11 association failing; previously,
310 association succeeded, but hostpad forced disassociation immediately)
311 * driver_madwifi: added support for madwifi-ng
314 * added support for replacing user identity from EAP with RADIUS
315 User-Name attribute from Access-Accept message, if that is included,
316 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
317 tunneled identity into accounting messages when the RADIUS server
318 does not support better way of doing this with Class attribute)
319 * driver_madwifi: fixed EAPOL packet receive for configuration where
320 ath# is part of a bridge interface
321 * added a configuration file and log analyzer script for logwatch
322 * fixed EAPOL state machine step function to process all state
323 transitions before processing new events; this resolves a race
324 condition in which EAPOL-Start message could trigger hostapd to send
325 two EAP-Response/Identity frames to the authentication server
328 * added client CA list to the TLS certificate request in order to make
329 it easier for the client to select which certificate to use
330 * added experimental support for EAP-PSK
331 * added support for WE-19 (hostap, madwifi)
334 * fixed build without CONFIG_RSN_PREAUTH
335 * fixed FreeBSD build
338 * fixed PMKSA caching to copy User-Name and Class attributes so that
339 RADIUS accounting gets correct information
340 * start RADIUS accounting only after successful completion of WPA
341 4-Way Handshake if WPA-PSK is used
342 * fixed PMKSA caching for the case where STA (re)associates without
346 * EAP-PAX is now registered as EAP type 46
347 * fixed EAP-PAX MAC calculation
348 * fixed EAP-PAX CK and ICK key derivation
349 * renamed eap_authenticator configuration variable to eap_server to
350 better match with RFC 3748 (EAP) terminology
351 * driver_test: added support for testing hostapd with wpa_supplicant
352 by using test driver interface without any kernel drivers or network
356 * fixed RADIUS server initialization when only auth or acct server
357 is configured and the other one is left empty
358 * driver_madwifi: added support for RADIUS accounting
359 * driver_madwifi: added preliminary support for compiling against 'BSD'
360 branch of madwifi CVS tree
361 * driver_madwifi: fixed pairwise key removal to allow WPA reauth
362 without disassociation
363 * added support for reading additional certificates from PKCS#12 files
364 and adding them to the certificate chain
365 * fixed RADIUS Class attribute processing to only use Access-Accept
366 packets to update Class; previously, other RADIUS authentication
367 packets could have cleared Class attribute
368 * added support for more than one Class attribute in RADIUS packets
369 * added support for verifying certificate revocation list (CRL) when
370 using integrated EAP authenticator for EAP-TLS; new hostapd.conf
371 options 'check_crl'; CRL must be included in the ca_cert file for now
373 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
374 * added support for including network information into
375 EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
376 (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
377 * fixed a bug which caused some RSN pre-authentication cases to use
378 freed memory and potentially crash hostapd
379 * fixed private key loading for cases where passphrase is not set
380 * added support for sending TLS alerts and aborting authentication
381 when receiving a TLS alert
382 * fixed WPA2 to add PMKSA cache entry when using integrated EAP
384 * fixed PMKSA caching (EAP authentication was not skipped correctly
385 with the new state machine changes from IEEE 802.1X draft)
386 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
387 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
388 to be added to .config to include IPv6 support); for RADIUS server,
389 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
390 in RADIUS clients file can then use IPv6 format
391 * added experimental support for EAP-PAX
392 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with
393 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
395 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
398 * added support for configuring a forced PEAP version based on the
400 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
401 to terminate authentication
402 * fixed EAP identifier duplicate processing with the new IEEE 802.1X
404 * clear accounting data in the driver when starting a new accounting
406 * driver_madwifi: filter wireless events based on ifindex to allow more
407 than one network interface to be used
408 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
409 setting if the packet does not pass MIC verification (e.g., due to
410 incorrect PSK); previously, message 1/4 was not tried again if an
411 invalid message 2/4 was received
412 * fixed reconfiguration of RADIUS client retransmission timer when
413 adding a new message to the pending list; previously, timer was not
414 updated at this point and if there was a pending message with long
415 time for the next retry, the new message needed to wait that long for
419 * added support for configuring multiple allowed EAP types for Phase 2
420 authentication (EAP-PEAP, EAP-TTLS)
421 * fixed EAPOL-Start processing to trigger WPA reauthentication
422 (previously, only EAPOL authentication was done)
425 * added support for EAP-PEAP in the integrated EAP authenticator
426 * added support for EAP-GTC in the integrated EAP authenticator
427 * added support for configuring list of EAP methods for Phase 1 so that
428 the integrated EAP authenticator can, e.g., use the wildcard entry
429 for EAP-TLS and EAP-PEAP
430 * added support for EAP-TTLS in the integrated EAP authenticator
431 * added support for EAP-SIM in the integrated EAP authenticator
432 * added support for using hostapd as a RADIUS authentication server
433 with the integrated EAP authenticator taking care of EAP
434 authentication (new hostapd.conf options: radius_server_clients and
435 radius_server_auth_port); this is not included in default build; use
436 CONFIG_RADIUS_SERVER=y in .config to include
439 * removed 'daemonize' configuration file option since it has not really
440 been used at all for more than year
441 * driver_madwifi: fixed group key setup and added get_ssid method
442 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator
445 * added support for integrated EAP-TLS authentication (new hostapd.conf
446 variables: ca_cert, server_cert, private_key, private_key_passwd);
447 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
448 external RADIUS server
449 * added support for reading PKCS#12 (PFX) files (as a replacement for
450 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
452 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
453 * added support for Acct-{Input,Output}-Gigawords
454 * added support for Event-Timestamp (in RADIUS Accounting-Requests)
455 * added support for RADIUS Authentication Client MIB (RFC2618)
456 * added support for RADIUS Accounting Client MIB (RFC2620)
457 * made EAP re-authentication period configurable (eap_reauth_period)
458 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
459 * fixed EAPOL state machine to stop if STA is removed during
460 eapol_sm_step(); this fixes at least one segfault triggering bug with
461 IEEE 802.11i pre-authentication
462 * added support for multiple WPA pre-shared keys (e.g., one for each
463 client MAC address or keys shared by a group of clients);
464 new hostapd.conf field wpa_psk_file for setting path to a text file
465 containing PSKs, see hostapd.wpa_psk for an example
466 * added support for multiple driver interfaces to allow hostapd to be
467 used with other drivers
468 * added wired authenticator driver interface (driver=wired in
469 hostapd.conf, see wired.conf for example configuration)
470 * added madwifi driver interface (driver=madwifi in hostapd.conf, see
471 madwifi.conf for example configuration; Note: include files from
472 madwifi project is needed for building and a configuration file,
473 .config, needs to be created in hostapd directory with
474 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
476 * fixed an alignment issue that could cause SHA-1 to fail on some
477 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
479 * fixed RADIUS reconnection after an error in sending interim
481 * added hostapd control interface for external programs and an example
482 CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
483 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
484 'hostapd_cli sta <addr>')
485 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
486 * added support for strict GTK rekeying (wpa_strict_rekey in
488 * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
489 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
491 * added Prism54 driver interface (driver=prism54 in hostapd.conf;
492 note: .config needs to be created in hostapd directory with
493 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
495 * dual-licensed hostapd (GPLv2 and BSD licenses)
496 * fixed RADIUS accounting to generate a new session id for cases where
497 a station reassociates without first being complete deauthenticated
498 * fixed STA disassociation handler to mark next timeout state to
499 deauthenticate the station, i.e., skip long wait for inactivity poll
500 and extra disassociation, if the STA disassociates without
502 * added integrated EAP authenticator that can be used instead of
503 external RADIUS authentication server; currently, only EAP-MD5 is
504 supported, so this cannot yet be used for key distribution; the EAP
505 method interface is generic, though, so adding new EAP methods should
506 be straightforward; new hostapd.conf variables: 'eap_authenticator'
507 and 'eap_user_file'; this obsoletes "minimal authentication server"
508 ('minimal_eap' in hostapd.conf) which is now removed
509 * added support for FreeBSD and driver interface for the BSD net80211
510 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
511 .config); please note that some of the required kernel mods have not
514 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
515 * fixed some accounting cases where Accounting-Start was sent when
516 IEEE 802.1X port was being deauthorized
519 * modified RADIUS client to re-connect the socket in case of certain
520 error codes that are generated when a network interface state is
521 changes (e.g., when IP address changes or the interface is set UP)
522 * fixed couple of cases where EAPOL state for a station was freed
523 twice causing a segfault for hostapd
524 * fixed couple of bugs in processing WPA deauthentication (freed data
528 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
529 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
530 cases where STAs dropped multicast frames as replay attacks
531 * added support for copying RADIUS Attribute 'Class' from
532 authentication messages into accounting messages
533 * send canned EAP failure if RADIUS server sends Access-Reject without
534 EAP message (previously, Supplicant was not notified in this case)
535 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
536 not start EAPOL state machines if the STA selected to use WPA-PSK)
539 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
540 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
541 (i.e., IEEE 802.11i/D3.0)
542 - supports WPA-only, RSN-only, and mixed WPA/RSN mode
543 - both WPA-PSK and WPA-RADIUS/EAP are supported
544 - PMKSA caching and pre-authentication
545 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
546 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
547 rsn_preauth, rsn_preauth_interfaces
548 * fixed interim accounting to remove any pending accounting messages
549 to the STA before sending a new one
552 * added support for Acct-Interim-Interval:
553 - draft-ietf-radius-acct-interim-01.txt
554 - use Acct-Interim-Interval attribute from Access-Accept if local
555 'radius_acct_interim_interval' is not set
556 - allow different update intervals for each STA
557 * fixed event loop to call signal handlers only after returning from
558 the real signal handler
559 * reset sta->timeout_next after successful association to make sure
560 that the previously registered inactivity timer will not remove the
561 STA immediately (e.g., if STA deauthenticates and re-associates
562 before the timer is triggered).
563 * added new hostapd.conf variable, nas_identifier, that can be used to
564 add an optional RADIUS Attribute, NAS-Identifier, into authentication
565 and accounting messages
566 * added support for Accounting-On and Accounting-Off messages
567 * fixed accounting session handling to send Accounting-Start only once
568 per session and not to send Accounting-Stop if the session was not
570 * fixed Accounting-Stop statistics in cases where the message was
571 previously sent after the kernel entry for the STA (and/or IEEE
572 802.1X data) was removed
577 Older changes up to and including v0.1.0 are included in the ChangeLog
578 of the Host AP driver.
