4 * fixed Reassociation Response callback processing when using internal
5 MLME (driver_{hostap,nl80211,test}.c)
6 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
7 * copy optional Proxy-State attributes into RADIUS response when acting
8 as a RADIUS authentication server
9 * fixed EAPOL state machine to handle a case in which no response is
10 received from the RADIUS authentication server; previous version
11 could have triggered a crash in some cases after a timeout
12 * fixed EAP-SIM/AKA realm processing to allow decorated usernames to
14 * added a workaround for EAP-SIM/AKA peers that include incorrect null
15 termination in the username
16 * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER
17 attribute in notification messages only when using fast
19 * fixed EAP-SIM Start response processing for fast reauthentication
21 * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST}
22 phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method
25 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
26 lengths properly to avoid potential crash caused by invalid messages
27 * added data structure for storing allocated buffers (struct wpabuf);
28 this does not affect hostapd usage, but many of the APIs changed
29 and various interfaces (e.g., EAP) is not compatible with old
31 * added support for protecting EAP-AKA/Identity messages with
32 AT_CHECKCODE (optional feature in RFC 4187)
33 * added support for protected result indication with AT_RESULT_IND for
34 EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1)
35 * added support for configuring EAP-TTLS phase 2 non-EAP methods in
36 EAP server configuration; previously all four were enabled for every
37 phase 2 user, now all four are disabled by default and need to be
38 enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP,
40 * removed old debug printing mechanism and the related 'debug'
41 parameter in the configuration file; debug verbosity is now set with
42 -d (or -dd) command line arguments
43 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
44 only shared key/password authentication is supported in this version
47 * added experimental, integrated TLSv1 server implementation with the
48 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
49 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
50 .config); this can be useful, e.g., if the target system does not
51 have a suitable TLS library and a minimal code size is required
52 * added support for EAP-FAST server method to the integrated EAP
54 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
55 draft (draft-ietf-emu-eap-gpsk-07.txt)
56 * added a new configuration parameter, rsn_pairwise, to allow different
57 pairwise cipher suites to be enabled for WPA and RSN/WPA2
58 (note: if wpa_pairwise differs from rsn_pairwise, the driver will
59 either need to support this or will have to use the WPA/RSN IEs from
60 hostapd; currently, the included madwifi and bsd driver interfaces do
61 not have support for this)
62 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
65 * added experimental IEEE 802.11r/D6.0 support
66 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
67 * updated EAP-PSK to use the IANA-allocated EAP type 47
68 * fixed EAP-PSK bit ordering of the Flags field
69 * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
70 by reading wpa_psk_file [Bug 181]
71 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
72 * fixed IPv6 connection to RADIUS accounting server
73 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
74 draft (draft-ietf-emu-eap-gpsk-04.txt)
75 * hlr_auc_gw: read GSM triplet file into memory and rotate through the
76 entries instead of only using the same three triplets every time
77 (this does not work properly with tests using multiple clients, but
78 provides bit better triplet data for testing a single client; anyway,
79 if a better quality triplets are needed, GSM-Milenage should be used
80 instead of hardcoded triplet file)
81 * fixed EAP-MSCHAPv2 server to use a space between S and M parameters
82 in Success Request [Bug 203]
83 * added support for sending EAP-AKA Notifications in error cases
84 * updated to use IEEE 802.11w/D2.0 for management frame protection
86 * RADIUS server: added support for processing duplicate messages
87 (retransmissions from RADIUS client) by replying with the previous
91 * added support for configuring and controlling multiple BSSes per
92 radio interface (bss=<ifname> in hostapd.conf); this is only
93 available with Devicescape and test driver interfaces
94 * fixed PMKSA cache update in the end of successful RSN
96 * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
97 for each STA based on RADIUS Access-Accept attributes); this requires
98 VLAN support from the kernel driver/802.11 stack and this is
99 currently only available with Devicescape and test driver interfaces
100 * driver_madwifi: fixed configuration of unencrypted modes (plaintext
101 and IEEE 802.1X without WEP)
102 * removed STAKey handshake since PeerKey handshake has replaced it in
103 IEEE 802.11ma and there are no known deployments of STAKey
104 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
105 draft (draft-ietf-emu-eap-gpsk-01.txt)
106 * added preliminary implementation of IEEE 802.11w/D1.0 (management
108 (Note: this requires driver support to work properly.)
109 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
110 * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
111 * hlr_auc_gw: added support for reading per-IMSI Milenage keys and
112 parameters from a text file to make it possible to implement proper
113 GSM/UMTS authentication server for multiple SIM/USIM cards using
115 * fixed session timeout processing with drivers that do not use
116 ieee802_11.c (e.g., madwifi)
119 * added 'hostapd_cli new_sta <addr>' command for adding a new STA into
120 hostapd (e.g., to initialize wired network authentication based on an
122 * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
123 using WPA2 even if PMKSA caching is not used
124 * added -P<pid file> argument for hostapd to write the current process
126 * added support for RADIUS Authentication Server MIB (RFC 2619)
129 * fixed nt_password_hash build [Bug 144]
130 * added PeerKey handshake implementation for IEEE 802.11e
131 direct link setup (DLS) to replace STAKey handshake
132 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
133 draft-clancy-emu-eap-shared-secret-00.txt)
134 * fixed a segmentation fault when RSN pre-authentication was completed
135 successfully [Bug 152]
138 * do not build nt_password_hash and hlr_auc_gw by default to avoid
139 requiring a TLS library for a successful build; these programs can be
140 build with 'make nt_password_hash' and 'make hlr_auc_gw'
141 * added a new configuration option, eapol_version, that can be used to
142 set EAPOL version to 1 (default is 2) to work around broken client
143 implementations that drop EAPOL frames which use version number 2
145 * added support for EAP-SAKE (no EAP method number allocated yet, so
146 this is using the same experimental type 255 as EAP-PSK)
147 * fixed EAP-MSCHAPv2 message length validation
150 * fixed stdarg use in hostapd_logger(): if both stdout and syslog
151 logging was enabled, hostapd could trigger a segmentation fault in
152 vsyslog on some CPU -- C library combinations
153 * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
154 program to make it easier to use for implementing real SS7 gateway;
155 eap_sim_db is not anymore used as a file name for GSM authentication
156 triplets; instead, it is path to UNIX domain socket that will be used
157 to communicate with the external gateway program (e.g., hlr_auc_gw)
158 * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
159 local information (GSM authentication triplets from a text file and
160 hardcoded AKA authentication data); this can be used to test EAP-SIM
162 * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
163 to make it possible to test EAP-AKA with real USIM cards (this is
164 disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
166 * driver_madwifi: added support for getting station RSN IE from
167 madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
168 broken with earlier change (r1357) in the driver
169 * changed EAP method registration to use a dynamic list of methods
170 instead of a static list generated at build time
171 * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
173 * added ap_max_inactivity configuration parameter
176 * driver_test: added better support for multiple APs and STAs by using
177 a directory with sockets that include MAC address for each device in
178 the name (test_socket=DIR:/tmp/test)
179 * added support for EAP expanded type (vendor specific EAP methods)
181 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
182 * added experimental STAKey handshake implementation for IEEE 802.11e
183 direct link setup (DLS); note: this is disabled by default in both
184 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
186 * added support for EAP methods to use callbacks to external programs
187 by buffering a pending request and processing it after the EAP method
189 * improved EAP-SIM database interface to allow external request to GSM
190 HLR/AuC without blocking hostapd process
191 * added support for using EAP-SIM pseudonyms and fast re-authentication
192 * added support for EAP-AKA in the integrated EAP authenticator
193 * added support for matching EAP identity prefixes (e.g., "1"*) in EAP
194 user database to allow EAP-SIM/AKA selection without extra roundtrip
195 for EAP-Nak negotiation
196 * added support for storing EAP user password as NtPasswordHash instead
197 of plaintext password when using MSCHAP or MSCHAPv2 for
198 authentication (hash:<16-octet hex value>); added nt_password_hash
199 tool for hashing password to generate NtPasswordHash
201 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
202 * driver_wired: fixed EAPOL sending to optionally use PAE group address
203 as the destination instead of supplicant MAC address; this is
204 disabled by default, but should be enabled with use_pae_group_addr=1
205 in configuration file if the wired interface is used by only one
206 device at the time (common switch configuration)
207 * driver_madwifi: configure driver to use TKIP countermeasures in order
208 to get correct behavior (IEEE 802.11 association failing; previously,
209 association succeeded, but hostpad forced disassociation immediately)
210 * driver_madwifi: added support for madwifi-ng
213 * added support for replacing user identity from EAP with RADIUS
214 User-Name attribute from Access-Accept message, if that is included,
215 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
216 tunneled identity into accounting messages when the RADIUS server
217 does not support better way of doing this with Class attribute)
218 * driver_madwifi: fixed EAPOL packet receive for configuration where
219 ath# is part of a bridge interface
220 * added a configuration file and log analyzer script for logwatch
221 * fixed EAPOL state machine step function to process all state
222 transitions before processing new events; this resolves a race
223 condition in which EAPOL-Start message could trigger hostapd to send
224 two EAP-Response/Identity frames to the authentication server
227 * added client CA list to the TLS certificate request in order to make
228 it easier for the client to select which certificate to use
229 * added experimental support for EAP-PSK
230 * added support for WE-19 (hostap, madwifi)
233 * fixed build without CONFIG_RSN_PREAUTH
234 * fixed FreeBSD build
237 * fixed PMKSA caching to copy User-Name and Class attributes so that
238 RADIUS accounting gets correct information
239 * start RADIUS accounting only after successful completion of WPA
240 4-Way Handshake if WPA-PSK is used
241 * fixed PMKSA caching for the case where STA (re)associates without
245 * EAP-PAX is now registered as EAP type 46
246 * fixed EAP-PAX MAC calculation
247 * fixed EAP-PAX CK and ICK key derivation
248 * renamed eap_authenticator configuration variable to eap_server to
249 better match with RFC 3748 (EAP) terminology
250 * driver_test: added support for testing hostapd with wpa_supplicant
251 by using test driver interface without any kernel drivers or network
255 * fixed RADIUS server initialization when only auth or acct server
256 is configured and the other one is left empty
257 * driver_madwifi: added support for RADIUS accounting
258 * driver_madwifi: added preliminary support for compiling against 'BSD'
259 branch of madwifi CVS tree
260 * driver_madwifi: fixed pairwise key removal to allow WPA reauth
261 without disassociation
262 * added support for reading additional certificates from PKCS#12 files
263 and adding them to the certificate chain
264 * fixed RADIUS Class attribute processing to only use Access-Accept
265 packets to update Class; previously, other RADIUS authentication
266 packets could have cleared Class attribute
267 * added support for more than one Class attribute in RADIUS packets
268 * added support for verifying certificate revocation list (CRL) when
269 using integrated EAP authenticator for EAP-TLS; new hostapd.conf
270 options 'check_crl'; CRL must be included in the ca_cert file for now
272 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
273 * added support for including network information into
274 EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
275 (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
276 * fixed a bug which caused some RSN pre-authentication cases to use
277 freed memory and potentially crash hostapd
278 * fixed private key loading for cases where passphrase is not set
279 * added support for sending TLS alerts and aborting authentication
280 when receiving a TLS alert
281 * fixed WPA2 to add PMKSA cache entry when using integrated EAP
283 * fixed PMKSA caching (EAP authentication was not skipped correctly
284 with the new state machine changes from IEEE 802.1X draft)
285 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
286 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
287 to be added to .config to include IPv6 support); for RADIUS server,
288 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
289 in RADIUS clients file can then use IPv6 format
290 * added experimental support for EAP-PAX
291 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with
292 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
294 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
297 * added support for configuring a forced PEAP version based on the
299 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
300 to terminate authentication
301 * fixed EAP identifier duplicate processing with the new IEEE 802.1X
303 * clear accounting data in the driver when starting a new accounting
305 * driver_madwifi: filter wireless events based on ifindex to allow more
306 than one network interface to be used
307 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
308 setting if the packet does not pass MIC verification (e.g., due to
309 incorrect PSK); previously, message 1/4 was not tried again if an
310 invalid message 2/4 was received
311 * fixed reconfiguration of RADIUS client retransmission timer when
312 adding a new message to the pending list; previously, timer was not
313 updated at this point and if there was a pending message with long
314 time for the next retry, the new message needed to wait that long for
318 * added support for configuring multiple allowed EAP types for Phase 2
319 authentication (EAP-PEAP, EAP-TTLS)
320 * fixed EAPOL-Start processing to trigger WPA reauthentication
321 (previously, only EAPOL authentication was done)
324 * added support for EAP-PEAP in the integrated EAP authenticator
325 * added support for EAP-GTC in the integrated EAP authenticator
326 * added support for configuring list of EAP methods for Phase 1 so that
327 the integrated EAP authenticator can, e.g., use the wildcard entry
328 for EAP-TLS and EAP-PEAP
329 * added support for EAP-TTLS in the integrated EAP authenticator
330 * added support for EAP-SIM in the integrated EAP authenticator
331 * added support for using hostapd as a RADIUS authentication server
332 with the integrated EAP authenticator taking care of EAP
333 authentication (new hostapd.conf options: radius_server_clients and
334 radius_server_auth_port); this is not included in default build; use
335 CONFIG_RADIUS_SERVER=y in .config to include
338 * removed 'daemonize' configuration file option since it has not really
339 been used at all for more than year
340 * driver_madwifi: fixed group key setup and added get_ssid method
341 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator
344 * added support for integrated EAP-TLS authentication (new hostapd.conf
345 variables: ca_cert, server_cert, private_key, private_key_passwd);
346 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
347 external RADIUS server
348 * added support for reading PKCS#12 (PFX) files (as a replacement for
349 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
351 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
352 * added support for Acct-{Input,Output}-Gigawords
353 * added support for Event-Timestamp (in RADIUS Accounting-Requests)
354 * added support for RADIUS Authentication Client MIB (RFC2618)
355 * added support for RADIUS Accounting Client MIB (RFC2620)
356 * made EAP re-authentication period configurable (eap_reauth_period)
357 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
358 * fixed EAPOL state machine to stop if STA is removed during
359 eapol_sm_step(); this fixes at least one segfault triggering bug with
360 IEEE 802.11i pre-authentication
361 * added support for multiple WPA pre-shared keys (e.g., one for each
362 client MAC address or keys shared by a group of clients);
363 new hostapd.conf field wpa_psk_file for setting path to a text file
364 containing PSKs, see hostapd.wpa_psk for an example
365 * added support for multiple driver interfaces to allow hostapd to be
366 used with other drivers
367 * added wired authenticator driver interface (driver=wired in
368 hostapd.conf, see wired.conf for example configuration)
369 * added madwifi driver interface (driver=madwifi in hostapd.conf, see
370 madwifi.conf for example configuration; Note: include files from
371 madwifi project is needed for building and a configuration file,
372 .config, needs to be created in hostapd directory with
373 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
375 * fixed an alignment issue that could cause SHA-1 to fail on some
376 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
378 * fixed RADIUS reconnection after an error in sending interim
380 * added hostapd control interface for external programs and an example
381 CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
382 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
383 'hostapd_cli sta <addr>')
384 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
385 * added support for strict GTK rekeying (wpa_strict_rekey in
387 * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
388 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
390 * added Prism54 driver interface (driver=prism54 in hostapd.conf;
391 note: .config needs to be created in hostapd directory with
392 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
394 * dual-licensed hostapd (GPLv2 and BSD licenses)
395 * fixed RADIUS accounting to generate a new session id for cases where
396 a station reassociates without first being complete deauthenticated
397 * fixed STA disassociation handler to mark next timeout state to
398 deauthenticate the station, i.e., skip long wait for inactivity poll
399 and extra disassociation, if the STA disassociates without
401 * added integrated EAP authenticator that can be used instead of
402 external RADIUS authentication server; currently, only EAP-MD5 is
403 supported, so this cannot yet be used for key distribution; the EAP
404 method interface is generic, though, so adding new EAP methods should
405 be straightforward; new hostapd.conf variables: 'eap_authenticator'
406 and 'eap_user_file'; this obsoletes "minimal authentication server"
407 ('minimal_eap' in hostapd.conf) which is now removed
408 * added support for FreeBSD and driver interface for the BSD net80211
409 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
410 .config); please note that some of the required kernel mods have not
413 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
414 * fixed some accounting cases where Accounting-Start was sent when
415 IEEE 802.1X port was being deauthorized
418 * modified RADIUS client to re-connect the socket in case of certain
419 error codes that are generated when a network interface state is
420 changes (e.g., when IP address changes or the interface is set UP)
421 * fixed couple of cases where EAPOL state for a station was freed
422 twice causing a segfault for hostapd
423 * fixed couple of bugs in processing WPA deauthentication (freed data
427 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
428 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
429 cases where STAs dropped multicast frames as replay attacks
430 * added support for copying RADIUS Attribute 'Class' from
431 authentication messages into accounting messages
432 * send canned EAP failure if RADIUS server sends Access-Reject without
433 EAP message (previously, Supplicant was not notified in this case)
434 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
435 not start EAPOL state machines if the STA selected to use WPA-PSK)
438 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
439 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
440 (i.e., IEEE 802.11i/D3.0)
441 - supports WPA-only, RSN-only, and mixed WPA/RSN mode
442 - both WPA-PSK and WPA-RADIUS/EAP are supported
443 - PMKSA caching and pre-authentication
444 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
445 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
446 rsn_preauth, rsn_preauth_interfaces
447 * fixed interim accounting to remove any pending accounting messages
448 to the STA before sending a new one
451 * added support for Acct-Interim-Interval:
452 - draft-ietf-radius-acct-interim-01.txt
453 - use Acct-Interim-Interval attribute from Access-Accept if local
454 'radius_acct_interim_interval' is not set
455 - allow different update intervals for each STA
456 * fixed event loop to call signal handlers only after returning from
457 the real signal handler
458 * reset sta->timeout_next after successful association to make sure
459 that the previously registered inactivity timer will not remove the
460 STA immediately (e.g., if STA deauthenticates and re-associates
461 before the timer is triggered).
462 * added new hostapd.conf variable, nas_identifier, that can be used to
463 add an optional RADIUS Attribute, NAS-Identifier, into authentication
464 and accounting messages
465 * added support for Accounting-On and Accounting-Off messages
466 * fixed accounting session handling to send Accounting-Start only once
467 per session and not to send Accounting-Stop if the session was not
469 * fixed Accounting-Stop statistics in cases where the message was
470 previously sent after the kernel entry for the STA (and/or IEEE
471 802.1X data) was removed
476 Older changes up to and including v0.1.0 are included in the ChangeLog
477 of the Host AP driver.
