4 * updated driver_devicescape.c to build with the current
5 wireless-dev.git tree and net/d80211 changes
6 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
7 draft (draft-ietf-emu-eap-gpsk-03.txt)
8 * fixed EAP-MSCHAPv2 server to use a space between S and M parameters
9 in Success Request [Bug 203]
10 * added support for sending EAP-AKA Notifications in error cases
11 * RADIUS server: added support for processing duplicate messages
12 (retransmissions from RADIUS client) by replying with the previous
16 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
17 * updated EAP-PSK to use the IANA-allocated EAP type 47
18 * fixed EAP-PSK bit ordering of the Flags field
19 * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
20 by reading wpa_psk_file [Bug 181]
21 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
22 * fixed IPv6 connection to RADIUS accounting server
25 * added support for configuring and controlling multiple BSSes per
26 radio interface (bss=<ifname> in hostapd.conf); this is only
27 available with Devicescape and test driver interfaces
28 * fixed PMKSA cache update in the end of successful RSN
30 * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
31 for each STA based on RADIUS Access-Accept attributes); this requires
32 VLAN support from the kernel driver/802.11 stack and this is
33 currently only available with Devicescape and test driver interfaces
34 * driver_madwifi: fixed configuration of unencrypted modes (plaintext
35 and IEEE 802.1X without WEP)
36 * removed STAKey handshake since PeerKey handshake has replaced it in
37 IEEE 802.11ma and there are no known deployments of STAKey
38 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
39 draft (draft-ietf-emu-eap-gpsk-01.txt)
40 * added preliminary implementation of IEEE 802.11w/D1.0 (management
42 (Note: this requires driver support to work properly.)
43 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
44 * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
45 * hlr_auc_gw: added support for reading per-IMSI Milenage keys and
46 parameters from a text file to make it possible to implement proper
47 GSM/UMTS authentication server for multiple SIM/USIM cards using
49 * fixed session timeout processing with drivers that do not use
50 ieee802_11.c (e.g., madwifi)
53 * added 'hostapd_cli new_sta <addr>' command for adding a new STA into
54 hostapd (e.g., to initialize wired network authentication based on an
56 * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
57 using WPA2 even if PMKSA caching is not used
58 * added -P<pid file> argument for hostapd to write the current process
60 * added support for RADIUS Authentication Server MIB (RFC 2619)
63 * fixed nt_password_hash build [Bug 144]
64 * added PeerKey handshake implementation for IEEE 802.11e
65 direct link setup (DLS) to replace STAKey handshake
66 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
67 draft-clancy-emu-eap-shared-secret-00.txt)
68 * fixed a segmentation fault when RSN pre-authentication was completed
69 successfully [Bug 152]
72 * do not build nt_password_hash and hlr_auc_gw by default to avoid
73 requiring a TLS library for a successful build; these programs can be
74 build with 'make nt_password_hash' and 'make hlr_auc_gw'
75 * added a new configuration option, eapol_version, that can be used to
76 set EAPOL version to 1 (default is 2) to work around broken client
77 implementations that drop EAPOL frames which use version number 2
79 * added support for EAP-SAKE (no EAP method number allocated yet, so
80 this is using the same experimental type 255 as EAP-PSK)
81 * fixed EAP-MSCHAPv2 message length validation
84 * fixed stdarg use in hostapd_logger(): if both stdout and syslog
85 logging was enabled, hostapd could trigger a segmentation fault in
86 vsyslog on some CPU -- C library combinations
87 * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
88 program to make it easier to use for implementing real SS7 gateway;
89 eap_sim_db is not anymore used as a file name for GSM authentication
90 triplets; instead, it is path to UNIX domain socket that will be used
91 to communicate with the external gateway program (e.g., hlr_auc_gw)
92 * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
93 local information (GSM authentication triplets from a text file and
94 hardcoded AKA authentication data); this can be used to test EAP-SIM
96 * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
97 to make it possible to test EAP-AKA with real USIM cards (this is
98 disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
100 * driver_madwifi: added support for getting station RSN IE from
101 madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
102 broken with earlier change (r1357) in the driver
103 * changed EAP method registration to use a dynamic list of methods
104 instead of a static list generated at build time
105 * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
107 * added ap_max_inactivity configuration parameter
110 * driver_test: added better support for multiple APs and STAs by using
111 a directory with sockets that include MAC address for each device in
112 the name (test_socket=DIR:/tmp/test)
113 * added support for EAP expanded type (vendor specific EAP methods)
115 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
116 * added experimental STAKey handshake implementation for IEEE 802.11e
117 direct link setup (DLS); note: this is disabled by default in both
118 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
120 * added support for EAP methods to use callbacks to external programs
121 by buffering a pending request and processing it after the EAP method
123 * improved EAP-SIM database interface to allow external request to GSM
124 HLR/AuC without blocking hostapd process
125 * added support for using EAP-SIM pseudonyms and fast re-authentication
126 * added support for EAP-AKA in the integrated EAP authenticator
127 * added support for matching EAP identity prefixes (e.g., "1"*) in EAP
128 user database to allow EAP-SIM/AKA selection without extra roundtrip
129 for EAP-Nak negotiation
130 * added support for storing EAP user password as NtPasswordHash instead
131 of plaintext password when using MSCHAP or MSCHAPv2 for
132 authentication (hash:<16-octet hex value>); added nt_password_hash
133 tool for hashing password to generate NtPasswordHash
135 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
136 * driver_wired: fixed EAPOL sending to optionally use PAE group address
137 as the destination instead of supplicant MAC address; this is
138 disabled by default, but should be enabled with use_pae_group_addr=1
139 in configuration file if the wired interface is used by only one
140 device at the time (common switch configuration)
141 * driver_madwifi: configure driver to use TKIP countermeasures in order
142 to get correct behavior (IEEE 802.11 association failing; previously,
143 association succeeded, but hostpad forced disassociation immediately)
144 * driver_madwifi: added support for madwifi-ng
147 * added support for replacing user identity from EAP with RADIUS
148 User-Name attribute from Access-Accept message, if that is included,
149 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
150 tunneled identity into accounting messages when the RADIUS server
151 does not support better way of doing this with Class attribute)
152 * driver_madwifi: fixed EAPOL packet receive for configuration where
153 ath# is part of a bridge interface
154 * added a configuration file and log analyzer script for logwatch
155 * fixed EAPOL state machine step function to process all state
156 transitions before processing new events; this resolves a race
157 condition in which EAPOL-Start message could trigger hostapd to send
158 two EAP-Response/Identity frames to the authentication server
161 * added client CA list to the TLS certificate request in order to make
162 it easier for the client to select which certificate to use
163 * added experimental support for EAP-PSK
164 * added support for WE-19 (hostap, madwifi)
167 * fixed build without CONFIG_RSN_PREAUTH
168 * fixed FreeBSD build
171 * fixed PMKSA caching to copy User-Name and Class attributes so that
172 RADIUS accounting gets correct information
173 * start RADIUS accounting only after successful completion of WPA
174 4-Way Handshake if WPA-PSK is used
175 * fixed PMKSA caching for the case where STA (re)associates without
179 * EAP-PAX is now registered as EAP type 46
180 * fixed EAP-PAX MAC calculation
181 * fixed EAP-PAX CK and ICK key derivation
182 * renamed eap_authenticator configuration variable to eap_server to
183 better match with RFC 3748 (EAP) terminology
184 * driver_test: added support for testing hostapd with wpa_supplicant
185 by using test driver interface without any kernel drivers or network
189 * fixed RADIUS server initialization when only auth or acct server
190 is configured and the other one is left empty
191 * driver_madwifi: added support for RADIUS accounting
192 * driver_madwifi: added preliminary support for compiling against 'BSD'
193 branch of madwifi CVS tree
194 * driver_madwifi: fixed pairwise key removal to allow WPA reauth
195 without disassociation
196 * added support for reading additional certificates from PKCS#12 files
197 and adding them to the certificate chain
198 * fixed RADIUS Class attribute processing to only use Access-Accept
199 packets to update Class; previously, other RADIUS authentication
200 packets could have cleared Class attribute
201 * added support for more than one Class attribute in RADIUS packets
202 * added support for verifying certificate revocation list (CRL) when
203 using integrated EAP authenticator for EAP-TLS; new hostapd.conf
204 options 'check_crl'; CRL must be included in the ca_cert file for now
206 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
207 * added support for including network information into
208 EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
209 (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
210 * fixed a bug which caused some RSN pre-authentication cases to use
211 freed memory and potentially crash hostapd
212 * fixed private key loading for cases where passphrase is not set
213 * added support for sending TLS alerts and aborting authentication
214 when receiving a TLS alert
215 * fixed WPA2 to add PMKSA cache entry when using integrated EAP
217 * fixed PMKSA caching (EAP authentication was not skipped correctly
218 with the new state machine changes from IEEE 802.1X draft)
219 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
220 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
221 to be added to .config to include IPv6 support); for RADIUS server,
222 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
223 in RADIUS clients file can then use IPv6 format
224 * added experimental support for EAP-PAX
225 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with
226 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
228 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
231 * added support for configuring a forced PEAP version based on the
233 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
234 to terminate authentication
235 * fixed EAP identifier duplicate processing with the new IEEE 802.1X
237 * clear accounting data in the driver when starting a new accounting
239 * driver_madwifi: filter wireless events based on ifindex to allow more
240 than one network interface to be used
241 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
242 setting if the packet does not pass MIC verification (e.g., due to
243 incorrect PSK); previously, message 1/4 was not tried again if an
244 invalid message 2/4 was received
245 * fixed reconfiguration of RADIUS client retransmission timer when
246 adding a new message to the pending list; previously, timer was not
247 updated at this point and if there was a pending message with long
248 time for the next retry, the new message needed to wait that long for
252 * added support for configuring multiple allowed EAP types for Phase 2
253 authentication (EAP-PEAP, EAP-TTLS)
254 * fixed EAPOL-Start processing to trigger WPA reauthentication
255 (previously, only EAPOL authentication was done)
258 * added support for EAP-PEAP in the integrated EAP authenticator
259 * added support for EAP-GTC in the integrated EAP authenticator
260 * added support for configuring list of EAP methods for Phase 1 so that
261 the integrated EAP authenticator can, e.g., use the wildcard entry
262 for EAP-TLS and EAP-PEAP
263 * added support for EAP-TTLS in the integrated EAP authenticator
264 * added support for EAP-SIM in the integrated EAP authenticator
265 * added support for using hostapd as a RADIUS authentication server
266 with the integrated EAP authenticator taking care of EAP
267 authentication (new hostapd.conf options: radius_server_clients and
268 radius_server_auth_port); this is not included in default build; use
269 CONFIG_RADIUS_SERVER=y in .config to include
272 * removed 'daemonize' configuration file option since it has not really
273 been used at all for more than year
274 * driver_madwifi: fixed group key setup and added get_ssid method
275 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator
278 * added support for integrated EAP-TLS authentication (new hostapd.conf
279 variables: ca_cert, server_cert, private_key, private_key_passwd);
280 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
281 external RADIUS server
282 * added support for reading PKCS#12 (PFX) files (as a replacement for
283 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
285 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
286 * added support for Acct-{Input,Output}-Gigawords
287 * added support for Event-Timestamp (in RADIUS Accounting-Requests)
288 * added support for RADIUS Authentication Client MIB (RFC2618)
289 * added support for RADIUS Accounting Client MIB (RFC2620)
290 * made EAP re-authentication period configurable (eap_reauth_period)
291 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
292 * fixed EAPOL state machine to stop if STA is removed during
293 eapol_sm_step(); this fixes at least one segfault triggering bug with
294 IEEE 802.11i pre-authentication
295 * added support for multiple WPA pre-shared keys (e.g., one for each
296 client MAC address or keys shared by a group of clients);
297 new hostapd.conf field wpa_psk_file for setting path to a text file
298 containing PSKs, see hostapd.wpa_psk for an example
299 * added support for multiple driver interfaces to allow hostapd to be
300 used with other drivers
301 * added wired authenticator driver interface (driver=wired in
302 hostapd.conf, see wired.conf for example configuration)
303 * added madwifi driver interface (driver=madwifi in hostapd.conf, see
304 madwifi.conf for example configuration; Note: include files from
305 madwifi project is needed for building and a configuration file,
306 .config, needs to be created in hostapd directory with
307 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
309 * fixed an alignment issue that could cause SHA-1 to fail on some
310 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
312 * fixed RADIUS reconnection after an error in sending interim
314 * added hostapd control interface for external programs and an example
315 CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
316 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
317 'hostapd_cli sta <addr>')
318 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
319 * added support for strict GTK rekeying (wpa_strict_rekey in
321 * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
322 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
324 * added Prism54 driver interface (driver=prism54 in hostapd.conf;
325 note: .config needs to be created in hostapd directory with
326 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
328 * dual-licensed hostapd (GPLv2 and BSD licenses)
329 * fixed RADIUS accounting to generate a new session id for cases where
330 a station reassociates without first being complete deauthenticated
331 * fixed STA disassociation handler to mark next timeout state to
332 deauthenticate the station, i.e., skip long wait for inactivity poll
333 and extra disassociation, if the STA disassociates without
335 * added integrated EAP authenticator that can be used instead of
336 external RADIUS authentication server; currently, only EAP-MD5 is
337 supported, so this cannot yet be used for key distribution; the EAP
338 method interface is generic, though, so adding new EAP methods should
339 be straightforward; new hostapd.conf variables: 'eap_authenticator'
340 and 'eap_user_file'; this obsoletes "minimal authentication server"
341 ('minimal_eap' in hostapd.conf) which is now removed
342 * added support for FreeBSD and driver interface for the BSD net80211
343 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
344 .config); please note that some of the required kernel mods have not
347 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
348 * fixed some accounting cases where Accounting-Start was sent when
349 IEEE 802.1X port was being deauthorized
352 * modified RADIUS client to re-connect the socket in case of certain
353 error codes that are generated when a network interface state is
354 changes (e.g., when IP address changes or the interface is set UP)
355 * fixed couple of cases where EAPOL state for a station was freed
356 twice causing a segfault for hostapd
357 * fixed couple of bugs in processing WPA deauthentication (freed data
361 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
362 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
363 cases where STAs dropped multicast frames as replay attacks
364 * added support for copying RADIUS Attribute 'Class' from
365 authentication messages into accounting messages
366 * send canned EAP failure if RADIUS server sends Access-Reject without
367 EAP message (previously, Supplicant was not notified in this case)
368 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
369 not start EAPOL state machines if the STA selected to use WPA-PSK)
372 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
373 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
374 (i.e., IEEE 802.11i/D3.0)
375 - supports WPA-only, RSN-only, and mixed WPA/RSN mode
376 - both WPA-PSK and WPA-RADIUS/EAP are supported
377 - PMKSA caching and pre-authentication
378 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
379 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
380 rsn_preauth, rsn_preauth_interfaces
381 * fixed interim accounting to remove any pending accounting messages
382 to the STA before sending a new one
385 * added support for Acct-Interim-Interval:
386 - draft-ietf-radius-acct-interim-01.txt
387 - use Acct-Interim-Interval attribute from Access-Accept if local
388 'radius_acct_interim_interval' is not set
389 - allow different update intervals for each STA
390 * fixed event loop to call signal handlers only after returning from
391 the real signal handler
392 * reset sta->timeout_next after successful association to make sure
393 that the previously registered inactivity timer will not remove the
394 STA immediately (e.g., if STA deauthenticates and re-associates
395 before the timer is triggered).
396 * added new hostapd.conf variable, nas_identifier, that can be used to
397 add an optional RADIUS Attribute, NAS-Identifier, into authentication
398 and accounting messages
399 * added support for Accounting-On and Accounting-Off messages
400 * fixed accounting session handling to send Accounting-Start only once
401 per session and not to send Accounting-Stop if the session was not
403 * fixed Accounting-Stop statistics in cases where the message was
404 previously sent after the kernel entry for the STA (and/or IEEE
405 802.1X data) was removed
410 Older changes up to and including v0.1.0 are included in the ChangeLog
411 of the Host AP driver.
