1 ChangeLog for hostapd
3 2009-11-21 - v0.7.0
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
14 authentication server
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]
21 * added number of code size optimizations to remove unnecessary
22 functionality from the program binary based on build configuration
23 (part of this automatic; part configurable with CONFIG_NO_* build
24 options)
25 * use shared driver wrapper files with wpa_supplicant
26 * driver_nl80211: multiple updates to provide support for new Linux
27 nl80211/mac80211 functionality
28 * updated management frame protection to use IEEE Std 802.11w-2009
29 * fixed number of small WPS issues and added workarounds to
30 interoperate with common deployed broken implementations
31 * added some IEEE 802.11n co-existance rules to disable 40 MHz channels
32 or modify primary/secondary channels if needed based on neighboring
33 networks
34 * added support for NFC out-of-band mechanism with WPS
35 * added preliminary support for IEEE 802.11r RIC processing
37 2009-01-06 - v0.6.7
38 * added support for Wi-Fi Protected Setup (WPS)
39 (hostapd can now be configured to act as an integrated WPS Registrar
40 and provision credentials for WPS Enrollees using PIN and PBC
41 methods; external wireless Registrar can configure the AP, but
42 external WLAN Manager Registrars are not supported); WPS support can
43 be enabled by adding CONFIG_WPS=y into .config and setting the
44 runtime configuration variables in hostapd.conf (see WPS section in
45 the example configuration file); new hostapd_cli commands wps_pin and
46 wps_pbc are used to configure WPS negotiation; see README-WPS for
47 more details
48 * added IEEE 802.11n HT capability configuration (ht_capab)
49 * added support for generating Country IE based on nl80211 regulatory
50 information (added if ieee80211d=1 in configuration)
51 * fixed WEP authentication (both Open System and Shared Key) with
52 mac80211
53 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
54 * added support for using driver_test over UDP socket
55 * changed EAP-GPSK to use the IANA assigned EAP method type 51
56 * updated management frame protection to use IEEE 802.11w/D7.0
57 * fixed retransmission of EAP requests if no response is received
59 2008-11-23 - v0.6.6
60 * added a new configuration option, wpa_ptk_rekey, that can be used to
61 enforce frequent PTK rekeying, e.g., to mitigate some attacks against
62 TKIP deficiencies
63 * updated OpenSSL code for EAP-FAST to use an updated version of the
64 session ticket overriding API that was included into the upstream
65 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
66 needed with that version anymore)
67 * changed channel flags configuration to read the information from
68 the driver (e.g., via driver_nl80211 when using mac80211) instead of
69 using hostapd as the source of the regulatory information (i.e.,
70 information from CRDA is now used with mac80211); this allows 5 GHz
71 channels to be used with hostapd (if allowed in the current
72 regulatory domain)
73 * fixed EAP-TLS message processing for the last TLS message if it is
74 large enough to require fragmentation (e.g., if a large Session
75 Ticket data is included)
76 * fixed listen interval configuration for nl80211 drivers
78 2008-11-01 - v0.6.5
79 * added support for SHA-256 as X.509 certificate digest when using the
80 internal X.509/TLSv1 implementation
81 * fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer
82 identity lengths)
83 * fixed internal TLSv1 implementation for abbreviated handshake (used
84 by EAP-FAST server)
85 * added support for setting VLAN ID for STAs based on local MAC ACL
86 (accept_mac_file) as an alternative for RADIUS server-based
87 configuration
88 * updated management frame protection to use IEEE 802.11w/D6.0
89 (adds a new association ping to protect against unauthenticated
90 authenticate or (re)associate request frames dropping association)
91 * added support for using SHA256-based stronger key derivation for WPA2
92 (IEEE 802.11w)
93 * added new "driver wrapper" for RADIUS-only configuration
94 (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config)
95 * fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2)
96 is enabled in configuration
97 * changed EAP-FAST configuration to use separate fields for A-ID and
98 A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed
99 16-octet len binary value for better interoperability with some peer
100 implementations; eap_fast_a_id is now configured as a hex string
101 * driver_nl80211: Updated to match the current Linux mac80211 AP mode
102 configuration (wireless-testing.git and Linux kernel releases
103 starting from 2.6.29)
105 2008-08-10 - v0.6.4
106 * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2
107 Identity Request if identity is already known
108 * added support for EAP Sequences in EAP-FAST Phase 2
109 * added support for EAP-TNC (Trusted Network Connect)
110 (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST
111 changes needed to run two methods in sequence (IF-T) and the IF-IMV
112 and IF-TNCCS interfaces from TNCS)
113 * added support for optional cryptobinding with PEAPv0
114 * added fragmentation support for EAP-TNC
115 * added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled)
116 data
117 * added support for opportunistic key caching (OKC)
119 2008-02-22 - v0.6.3
120 * fixed Reassociation Response callback processing when using internal
121 MLME (driver_{hostap,nl80211,test}.c)
122 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
123 * copy optional Proxy-State attributes into RADIUS response when acting
124 as a RADIUS authentication server
125 * fixed EAPOL state machine to handle a case in which no response is
126 received from the RADIUS authentication server; previous version
127 could have triggered a crash in some cases after a timeout
128 * fixed EAP-SIM/AKA realm processing to allow decorated usernames to
129 be used
130 * added a workaround for EAP-SIM/AKA peers that include incorrect null
131 termination in the username
132 * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER
133 attribute in notification messages only when using fast
134 reauthentication
135 * fixed EAP-SIM Start response processing for fast reauthentication
136 case
137 * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST}
138 phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method
140 2008-01-01 - v0.6.2
141 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
142 lengths properly to avoid potential crash caused by invalid messages
143 * added data structure for storing allocated buffers (struct wpabuf);
144 this does not affect hostapd usage, but many of the APIs changed
145 and various interfaces (e.g., EAP) is not compatible with old
146 versions
147 * added support for protecting EAP-AKA/Identity messages with
148 AT_CHECKCODE (optional feature in RFC 4187)
149 * added support for protected result indication with AT_RESULT_IND for
150 EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1)
151 * added support for configuring EAP-TTLS phase 2 non-EAP methods in
152 EAP server configuration; previously all four were enabled for every
153 phase 2 user, now all four are disabled by default and need to be
154 enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP,
155 TTLS-MSCHAPV2
156 * removed old debug printing mechanism and the related 'debug'
157 parameter in the configuration file; debug verbosity is now set with
158 -d (or -dd) command line arguments
159 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
160 only shared key/password authentication is supported in this version
162 2007-11-24 - v0.6.1
163 * added experimental, integrated TLSv1 server implementation with the
164 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
165 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
166 .config); this can be useful, e.g., if the target system does not
167 have a suitable TLS library and a minimal code size is required
168 * added support for EAP-FAST server method to the integrated EAP
169 server
170 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
171 draft (draft-ietf-emu-eap-gpsk-07.txt)
172 * added a new configuration parameter, rsn_pairwise, to allow different
173 pairwise cipher suites to be enabled for WPA and RSN/WPA2
174 (note: if wpa_pairwise differs from rsn_pairwise, the driver will
175 either need to support this or will have to use the WPA/RSN IEs from
176 hostapd; currently, the included madwifi and bsd driver interfaces do
177 not have support for this)
178 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
180 2007-05-28 - v0.6.0
181 * added experimental IEEE 802.11r/D6.0 support
182 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
183 * updated EAP-PSK to use the IANA-allocated EAP type 47
184 * fixed EAP-PSK bit ordering of the Flags field
185 * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
186 by reading wpa_psk_file [Bug 181]
187 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
188 * fixed IPv6 connection to RADIUS accounting server
189 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
190 draft (draft-ietf-emu-eap-gpsk-04.txt)
191 * hlr_auc_gw: read GSM triplet file into memory and rotate through the
192 entries instead of only using the same three triplets every time
193 (this does not work properly with tests using multiple clients, but
194 provides bit better triplet data for testing a single client; anyway,
195 if a better quality triplets are needed, GSM-Milenage should be used
196 instead of hardcoded triplet file)
197 * fixed EAP-MSCHAPv2 server to use a space between S and M parameters
198 in Success Request [Bug 203]
199 * added support for sending EAP-AKA Notifications in error cases
200 * updated to use IEEE 802.11w/D2.0 for management frame protection
201 (still experimental)
202 * RADIUS server: added support for processing duplicate messages
203 (retransmissions from RADIUS client) by replying with the previous
204 reply
206 2006-11-24 - v0.5.6
207 * added support for configuring and controlling multiple BSSes per
208 radio interface (bss=<ifname> in hostapd.conf); this is only
209 available with Devicescape and test driver interfaces
210 * fixed PMKSA cache update in the end of successful RSN
211 pre-authentication
212 * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
213 for each STA based on RADIUS Access-Accept attributes); this requires
214 VLAN support from the kernel driver/802.11 stack and this is
215 currently only available with Devicescape and test driver interfaces
216 * driver_madwifi: fixed configuration of unencrypted modes (plaintext
217 and IEEE 802.1X without WEP)
218 * removed STAKey handshake since PeerKey handshake has replaced it in
219 IEEE 802.11ma and there are no known deployments of STAKey
220 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
221 draft (draft-ietf-emu-eap-gpsk-01.txt)
222 * added preliminary implementation of IEEE 802.11w/D1.0 (management
223 frame protection)
224 (Note: this requires driver support to work properly.)
225 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
226 * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
227 * hlr_auc_gw: added support for reading per-IMSI Milenage keys and
228 parameters from a text file to make it possible to implement proper
229 GSM/UMTS authentication server for multiple SIM/USIM cards using
230 EAP-SIM/EAP-AKA
231 * fixed session timeout processing with drivers that do not use
232 ieee802_11.c (e.g., madwifi)
234 2006-08-27 - v0.5.5
235 * added 'hostapd_cli new_sta <addr>' command for adding a new STA into
236 hostapd (e.g., to initialize wired network authentication based on an
237 external signal)
238 * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
239 using WPA2 even if PMKSA caching is not used
240 * added -P<pid file> argument for hostapd to write the current process
241 id into a file
242 * added support for RADIUS Authentication Server MIB (RFC 2619)
244 2006-06-20 - v0.5.4
245 * fixed nt_password_hash build [Bug 144]
246 * added PeerKey handshake implementation for IEEE 802.11e
247 direct link setup (DLS) to replace STAKey handshake
248 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
249 draft-clancy-emu-eap-shared-secret-00.txt)
250 * fixed a segmentation fault when RSN pre-authentication was completed
251 successfully [Bug 152]
253 2006-04-27 - v0.5.3
254 * do not build nt_password_hash and hlr_auc_gw by default to avoid
255 requiring a TLS library for a successful build; these programs can be
256 build with 'make nt_password_hash' and 'make hlr_auc_gw'
257 * added a new configuration option, eapol_version, that can be used to
258 set EAPOL version to 1 (default is 2) to work around broken client
259 implementations that drop EAPOL frames which use version number 2
260 [Bug 89]
261 * added support for EAP-SAKE (no EAP method number allocated yet, so
262 this is using the same experimental type 255 as EAP-PSK)
263 * fixed EAP-MSCHAPv2 message length validation
265 2006-03-19 - v0.5.2
266 * fixed stdarg use in hostapd_logger(): if both stdout and syslog
267 logging was enabled, hostapd could trigger a segmentation fault in
268 vsyslog on some CPU -- C library combinations
269 * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
270 program to make it easier to use for implementing real SS7 gateway;
271 eap_sim_db is not anymore used as a file name for GSM authentication
272 triplets; instead, it is path to UNIX domain socket that will be used
273 to communicate with the external gateway program (e.g., hlr_auc_gw)
274 * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
275 local information (GSM authentication triplets from a text file and
276 hardcoded AKA authentication data); this can be used to test EAP-SIM
277 and EAP-AKA
278 * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
279 to make it possible to test EAP-AKA with real USIM cards (this is
280 disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
281 to enable this)
282 * driver_madwifi: added support for getting station RSN IE from
283 madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
284 broken with earlier change (r1357) in the driver
285 * changed EAP method registration to use a dynamic list of methods
286 instead of a static list generated at build time
287 * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
288 [Bug 125]
289 * added ap_max_inactivity configuration parameter
291 2006-01-29 - v0.5.1
292 * driver_test: added better support for multiple APs and STAs by using
293 a directory with sockets that include MAC address for each device in
294 the name (test_socket=DIR:/tmp/test)
295 * added support for EAP expanded type (vendor specific EAP methods)
297 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
298 * added experimental STAKey handshake implementation for IEEE 802.11e
299 direct link setup (DLS); note: this is disabled by default in both
300 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
301 and stakey=1)
302 * added support for EAP methods to use callbacks to external programs
303 by buffering a pending request and processing it after the EAP method
304 is ready to continue
305 * improved EAP-SIM database interface to allow external request to GSM
306 HLR/AuC without blocking hostapd process
307 * added support for using EAP-SIM pseudonyms and fast re-authentication
308 * added support for EAP-AKA in the integrated EAP authenticator
309 * added support for matching EAP identity prefixes (e.g., "1"*) in EAP
310 user database to allow EAP-SIM/AKA selection without extra roundtrip
311 for EAP-Nak negotiation
312 * added support for storing EAP user password as NtPasswordHash instead
313 of plaintext password when using MSCHAP or MSCHAPv2 for
314 authentication (hash:<16-octet hex value>); added nt_password_hash
315 tool for hashing password to generate NtPasswordHash
317 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
318 * driver_wired: fixed EAPOL sending to optionally use PAE group address
319 as the destination instead of supplicant MAC address; this is
320 disabled by default, but should be enabled with use_pae_group_addr=1
321 in configuration file if the wired interface is used by only one
322 device at the time (common switch configuration)
323 * driver_madwifi: configure driver to use TKIP countermeasures in order
324 to get correct behavior (IEEE 802.11 association failing; previously,
325 association succeeded, but hostpad forced disassociation immediately)
326 * driver_madwifi: added support for madwifi-ng
328 2005-10-27 - v0.4.6
329 * added support for replacing user identity from EAP with RADIUS
330 User-Name attribute from Access-Accept message, if that is included,
331 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
332 tunneled identity into accounting messages when the RADIUS server
333 does not support better way of doing this with Class attribute)
334 * driver_madwifi: fixed EAPOL packet receive for configuration where
335 ath# is part of a bridge interface
336 * added a configuration file and log analyzer script for logwatch
337 * fixed EAPOL state machine step function to process all state
338 transitions before processing new events; this resolves a race
339 condition in which EAPOL-Start message could trigger hostapd to send
340 two EAP-Response/Identity frames to the authentication server
342 2005-09-25 - v0.4.5
343 * added client CA list to the TLS certificate request in order to make
344 it easier for the client to select which certificate to use
345 * added experimental support for EAP-PSK
346 * added support for WE-19 (hostap, madwifi)
348 2005-08-21 - v0.4.4
349 * fixed build without CONFIG_RSN_PREAUTH
350 * fixed FreeBSD build
352 2005-06-26 - v0.4.3
353 * fixed PMKSA caching to copy User-Name and Class attributes so that
354 RADIUS accounting gets correct information
355 * start RADIUS accounting only after successful completion of WPA
356 4-Way Handshake if WPA-PSK is used
357 * fixed PMKSA caching for the case where STA (re)associates without
358 first disassociating
360 2005-06-12 - v0.4.2
361 * EAP-PAX is now registered as EAP type 46
362 * fixed EAP-PAX MAC calculation
363 * fixed EAP-PAX CK and ICK key derivation
364 * renamed eap_authenticator configuration variable to eap_server to
365 better match with RFC 3748 (EAP) terminology
366 * driver_test: added support for testing hostapd with wpa_supplicant
367 by using test driver interface without any kernel drivers or network
368 cards
370 2005-05-22 - v0.4.1
371 * fixed RADIUS server initialization when only auth or acct server
372 is configured and the other one is left empty
373 * driver_madwifi: added support for RADIUS accounting
374 * driver_madwifi: added preliminary support for compiling against 'BSD'
375 branch of madwifi CVS tree
376 * driver_madwifi: fixed pairwise key removal to allow WPA reauth
377 without disassociation
378 * added support for reading additional certificates from PKCS#12 files
379 and adding them to the certificate chain
380 * fixed RADIUS Class attribute processing to only use Access-Accept
381 packets to update Class; previously, other RADIUS authentication
382 packets could have cleared Class attribute
383 * added support for more than one Class attribute in RADIUS packets
384 * added support for verifying certificate revocation list (CRL) when
385 using integrated EAP authenticator for EAP-TLS; new hostapd.conf
386 options 'check_crl'; CRL must be included in the ca_cert file for now
388 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
389 * added support for including network information into
390 EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
391 (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
392 * fixed a bug which caused some RSN pre-authentication cases to use
393 freed memory and potentially crash hostapd
394 * fixed private key loading for cases where passphrase is not set
395 * added support for sending TLS alerts and aborting authentication
396 when receiving a TLS alert
397 * fixed WPA2 to add PMKSA cache entry when using integrated EAP
398 authenticator
399 * fixed PMKSA caching (EAP authentication was not skipped correctly
400 with the new state machine changes from IEEE 802.1X draft)
401 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
402 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
403 to be added to .config to include IPv6 support); for RADIUS server,
404 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
405 in RADIUS clients file can then use IPv6 format
406 * added experimental support for EAP-PAX
407 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with
408 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
410 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
412 2005-01-23 - v0.3.5
413 * added support for configuring a forced PEAP version based on the
414 Phase 1 identity
415 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
416 to terminate authentication
417 * fixed EAP identifier duplicate processing with the new IEEE 802.1X
418 draft
419 * clear accounting data in the driver when starting a new accounting
420 session
421 * driver_madwifi: filter wireless events based on ifindex to allow more
422 than one network interface to be used
423 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
424 setting if the packet does not pass MIC verification (e.g., due to
425 incorrect PSK); previously, message 1/4 was not tried again if an
426 invalid message 2/4 was received
427 * fixed reconfiguration of RADIUS client retransmission timer when
428 adding a new message to the pending list; previously, timer was not
429 updated at this point and if there was a pending message with long
430 time for the next retry, the new message needed to wait that long for
431 its first retry, too
433 2005-01-09 - v0.3.4
434 * added support for configuring multiple allowed EAP types for Phase 2
435 authentication (EAP-PEAP, EAP-TTLS)
436 * fixed EAPOL-Start processing to trigger WPA reauthentication
437 (previously, only EAPOL authentication was done)
439 2005-01-02 - v0.3.3
440 * added support for EAP-PEAP in the integrated EAP authenticator
441 * added support for EAP-GTC in the integrated EAP authenticator
442 * added support for configuring list of EAP methods for Phase 1 so that
443 the integrated EAP authenticator can, e.g., use the wildcard entry
444 for EAP-TLS and EAP-PEAP
445 * added support for EAP-TTLS in the integrated EAP authenticator
446 * added support for EAP-SIM in the integrated EAP authenticator
447 * added support for using hostapd as a RADIUS authentication server
448 with the integrated EAP authenticator taking care of EAP
449 authentication (new hostapd.conf options: radius_server_clients and
450 radius_server_auth_port); this is not included in default build; use
451 CONFIG_RADIUS_SERVER=y in .config to include
453 2004-12-19 - v0.3.2
454 * removed 'daemonize' configuration file option since it has not really
455 been used at all for more than year
456 * driver_madwifi: fixed group key setup and added get_ssid method
457 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator
459 2004-12-12 - v0.3.1
460 * added support for integrated EAP-TLS authentication (new hostapd.conf
461 variables: ca_cert, server_cert, private_key, private_key_passwd);
462 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
463 external RADIUS server
464 * added support for reading PKCS#12 (PFX) files (as a replacement for
465 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
467 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
468 * added support for Acct-{Input,Output}-Gigawords
469 * added support for Event-Timestamp (in RADIUS Accounting-Requests)
470 * added support for RADIUS Authentication Client MIB (RFC2618)
471 * added support for RADIUS Accounting Client MIB (RFC2620)
472 * made EAP re-authentication period configurable (eap_reauth_period)
473 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
474 * fixed EAPOL state machine to stop if STA is removed during
475 eapol_sm_step(); this fixes at least one segfault triggering bug with
476 IEEE 802.11i pre-authentication
477 * added support for multiple WPA pre-shared keys (e.g., one for each
478 client MAC address or keys shared by a group of clients);
479 new hostapd.conf field wpa_psk_file for setting path to a text file
480 containing PSKs, see hostapd.wpa_psk for an example
481 * added support for multiple driver interfaces to allow hostapd to be
482 used with other drivers
483 * added wired authenticator driver interface (driver=wired in
484 hostapd.conf, see wired.conf for example configuration)
485 * added madwifi driver interface (driver=madwifi in hostapd.conf, see
486 madwifi.conf for example configuration; Note: include files from
487 madwifi project is needed for building and a configuration file,
488 .config, needs to be created in hostapd directory with
489 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
490 build)
491 * fixed an alignment issue that could cause SHA-1 to fail on some
492 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
493 align variables)
494 * fixed RADIUS reconnection after an error in sending interim
495 accounting packets
496 * added hostapd control interface for external programs and an example
497 CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
498 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
499 'hostapd_cli sta <addr>')
500 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
501 * added support for strict GTK rekeying (wpa_strict_rekey in
502 hostapd.conf)
503 * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
504 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
505 IEEE 802.11F-2003)
506 * added Prism54 driver interface (driver=prism54 in hostapd.conf;
507 note: .config needs to be created in hostapd directory with
508 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
509 build)
510 * dual-licensed hostapd (GPLv2 and BSD licenses)
511 * fixed RADIUS accounting to generate a new session id for cases where
512 a station reassociates without first being complete deauthenticated
513 * fixed STA disassociation handler to mark next timeout state to
514 deauthenticate the station, i.e., skip long wait for inactivity poll
515 and extra disassociation, if the STA disassociates without
516 deauthenticating
517 * added integrated EAP authenticator that can be used instead of
518 external RADIUS authentication server; currently, only EAP-MD5 is
519 supported, so this cannot yet be used for key distribution; the EAP
520 method interface is generic, though, so adding new EAP methods should
521 be straightforward; new hostapd.conf variables: 'eap_authenticator'
522 and 'eap_user_file'; this obsoletes "minimal authentication server"
523 ('minimal_eap' in hostapd.conf) which is now removed
524 * added support for FreeBSD and driver interface for the BSD net80211
525 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
526 .config); please note that some of the required kernel mods have not
527 yet been committed
529 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
530 * fixed some accounting cases where Accounting-Start was sent when
531 IEEE 802.1X port was being deauthorized
533 2004-06-20 - v0.2.3
534 * modified RADIUS client to re-connect the socket in case of certain
535 error codes that are generated when a network interface state is
536 changes (e.g., when IP address changes or the interface is set UP)
537 * fixed couple of cases where EAPOL state for a station was freed
538 twice causing a segfault for hostapd
539 * fixed couple of bugs in processing WPA deauthentication (freed data
540 was used)
542 2004-05-31 - v0.2.2
543 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
544 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
545 cases where STAs dropped multicast frames as replay attacks
546 * added support for copying RADIUS Attribute 'Class' from
547 authentication messages into accounting messages
548 * send canned EAP failure if RADIUS server sends Access-Reject without
549 EAP message (previously, Supplicant was not notified in this case)
550 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
551 not start EAPOL state machines if the STA selected to use WPA-PSK)
553 2004-05-06 - v0.2.1
554 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
555 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
556 (i.e., IEEE 802.11i/D3.0)
557 - supports WPA-only, RSN-only, and mixed WPA/RSN mode
558 - both WPA-PSK and WPA-RADIUS/EAP are supported
559 - PMKSA caching and pre-authentication
560 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
561 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
562 rsn_preauth, rsn_preauth_interfaces
563 * fixed interim accounting to remove any pending accounting messages
564 to the STA before sending a new one
566 2004-02-15 - v0.2.0
567 * added support for Acct-Interim-Interval:
568 - draft-ietf-radius-acct-interim-01.txt
569 - use Acct-Interim-Interval attribute from Access-Accept if local
570 'radius_acct_interim_interval' is not set
571 - allow different update intervals for each STA
572 * fixed event loop to call signal handlers only after returning from
573 the real signal handler
574 * reset sta->timeout_next after successful association to make sure
575 that the previously registered inactivity timer will not remove the
576 STA immediately (e.g., if STA deauthenticates and re-associates
577 before the timer is triggered).
578 * added new hostapd.conf variable, nas_identifier, that can be used to
579 add an optional RADIUS Attribute, NAS-Identifier, into authentication
580 and accounting messages
581 * added support for Accounting-On and Accounting-Off messages
582 * fixed accounting session handling to send Accounting-Start only once
583 per session and not to send Accounting-Stop if the session was not
584 initialized properly
585 * fixed Accounting-Stop statistics in cases where the message was
586 previously sent after the kernel entry for the STA (and/or IEEE
587 802.1X data) was removed
590 Note:
592 Older changes up to and including v0.1.0 are included in the ChangeLog
593 of the Host AP driver.
