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