4 * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2
5 Identity Request if identity is already known
6 * added support for EAP Sequences in EAP-FAST Phase 2
7 * added support for EAP-TNC (Trusted Network Connect)
8 (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST
9 changes needed to run two methods in sequence (IF-T) and the IF-IMV
10 and IF-TNCCS interfaces from TNCS)
11 * added support for optional cryptobinding with PEAPv0
14 * fixed Reassociation Response callback processing when using internal
15 MLME (driver_{hostap,nl80211,test}.c)
16 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
17 * copy optional Proxy-State attributes into RADIUS response when acting
18 as a RADIUS authentication server
19 * fixed EAPOL state machine to handle a case in which no response is
20 received from the RADIUS authentication server; previous version
21 could have triggered a crash in some cases after a timeout
22 * fixed EAP-SIM/AKA realm processing to allow decorated usernames to
24 * added a workaround for EAP-SIM/AKA peers that include incorrect null
25 termination in the username
26 * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER
27 attribute in notification messages only when using fast
29 * fixed EAP-SIM Start response processing for fast reauthentication
31 * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST}
32 phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method
35 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
36 lengths properly to avoid potential crash caused by invalid messages
37 * added data structure for storing allocated buffers (struct wpabuf);
38 this does not affect hostapd usage, but many of the APIs changed
39 and various interfaces (e.g., EAP) is not compatible with old
41 * added support for protecting EAP-AKA/Identity messages with
42 AT_CHECKCODE (optional feature in RFC 4187)
43 * added support for protected result indication with AT_RESULT_IND for
44 EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1)
45 * added support for configuring EAP-TTLS phase 2 non-EAP methods in
46 EAP server configuration; previously all four were enabled for every
47 phase 2 user, now all four are disabled by default and need to be
48 enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP,
50 * removed old debug printing mechanism and the related 'debug'
51 parameter in the configuration file; debug verbosity is now set with
52 -d (or -dd) command line arguments
53 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
54 only shared key/password authentication is supported in this version
57 * added experimental, integrated TLSv1 server implementation with the
58 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
59 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
60 .config); this can be useful, e.g., if the target system does not
61 have a suitable TLS library and a minimal code size is required
62 * added support for EAP-FAST server method to the integrated EAP
64 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
65 draft (draft-ietf-emu-eap-gpsk-07.txt)
66 * added a new configuration parameter, rsn_pairwise, to allow different
67 pairwise cipher suites to be enabled for WPA and RSN/WPA2
68 (note: if wpa_pairwise differs from rsn_pairwise, the driver will
69 either need to support this or will have to use the WPA/RSN IEs from
70 hostapd; currently, the included madwifi and bsd driver interfaces do
71 not have support for this)
72 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
75 * added experimental IEEE 802.11r/D6.0 support
76 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
77 * updated EAP-PSK to use the IANA-allocated EAP type 47
78 * fixed EAP-PSK bit ordering of the Flags field
79 * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
80 by reading wpa_psk_file [Bug 181]
81 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
82 * fixed IPv6 connection to RADIUS accounting server
83 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
84 draft (draft-ietf-emu-eap-gpsk-04.txt)
85 * hlr_auc_gw: read GSM triplet file into memory and rotate through the
86 entries instead of only using the same three triplets every time
87 (this does not work properly with tests using multiple clients, but
88 provides bit better triplet data for testing a single client; anyway,
89 if a better quality triplets are needed, GSM-Milenage should be used
90 instead of hardcoded triplet file)
91 * fixed EAP-MSCHAPv2 server to use a space between S and M parameters
92 in Success Request [Bug 203]
93 * added support for sending EAP-AKA Notifications in error cases
94 * updated to use IEEE 802.11w/D2.0 for management frame protection
96 * RADIUS server: added support for processing duplicate messages
97 (retransmissions from RADIUS client) by replying with the previous
101 * added support for configuring and controlling multiple BSSes per
102 radio interface (bss=<ifname> in hostapd.conf); this is only
103 available with Devicescape and test driver interfaces
104 * fixed PMKSA cache update in the end of successful RSN
106 * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
107 for each STA based on RADIUS Access-Accept attributes); this requires
108 VLAN support from the kernel driver/802.11 stack and this is
109 currently only available with Devicescape and test driver interfaces
110 * driver_madwifi: fixed configuration of unencrypted modes (plaintext
111 and IEEE 802.1X without WEP)
112 * removed STAKey handshake since PeerKey handshake has replaced it in
113 IEEE 802.11ma and there are no known deployments of STAKey
114 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
115 draft (draft-ietf-emu-eap-gpsk-01.txt)
116 * added preliminary implementation of IEEE 802.11w/D1.0 (management
118 (Note: this requires driver support to work properly.)
119 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
120 * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
121 * hlr_auc_gw: added support for reading per-IMSI Milenage keys and
122 parameters from a text file to make it possible to implement proper
123 GSM/UMTS authentication server for multiple SIM/USIM cards using
125 * fixed session timeout processing with drivers that do not use
126 ieee802_11.c (e.g., madwifi)
129 * added 'hostapd_cli new_sta <addr>' command for adding a new STA into
130 hostapd (e.g., to initialize wired network authentication based on an
132 * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
133 using WPA2 even if PMKSA caching is not used
134 * added -P<pid file> argument for hostapd to write the current process
136 * added support for RADIUS Authentication Server MIB (RFC 2619)
139 * fixed nt_password_hash build [Bug 144]
140 * added PeerKey handshake implementation for IEEE 802.11e
141 direct link setup (DLS) to replace STAKey handshake
142 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
143 draft-clancy-emu-eap-shared-secret-00.txt)
144 * fixed a segmentation fault when RSN pre-authentication was completed
145 successfully [Bug 152]
148 * do not build nt_password_hash and hlr_auc_gw by default to avoid
149 requiring a TLS library for a successful build; these programs can be
150 build with 'make nt_password_hash' and 'make hlr_auc_gw'
151 * added a new configuration option, eapol_version, that can be used to
152 set EAPOL version to 1 (default is 2) to work around broken client
153 implementations that drop EAPOL frames which use version number 2
155 * added support for EAP-SAKE (no EAP method number allocated yet, so
156 this is using the same experimental type 255 as EAP-PSK)
157 * fixed EAP-MSCHAPv2 message length validation
160 * fixed stdarg use in hostapd_logger(): if both stdout and syslog
161 logging was enabled, hostapd could trigger a segmentation fault in
162 vsyslog on some CPU -- C library combinations
163 * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
164 program to make it easier to use for implementing real SS7 gateway;
165 eap_sim_db is not anymore used as a file name for GSM authentication
166 triplets; instead, it is path to UNIX domain socket that will be used
167 to communicate with the external gateway program (e.g., hlr_auc_gw)
168 * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
169 local information (GSM authentication triplets from a text file and
170 hardcoded AKA authentication data); this can be used to test EAP-SIM
172 * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
173 to make it possible to test EAP-AKA with real USIM cards (this is
174 disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
176 * driver_madwifi: added support for getting station RSN IE from
177 madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
178 broken with earlier change (r1357) in the driver
179 * changed EAP method registration to use a dynamic list of methods
180 instead of a static list generated at build time
181 * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
183 * added ap_max_inactivity configuration parameter
186 * driver_test: added better support for multiple APs and STAs by using
187 a directory with sockets that include MAC address for each device in
188 the name (test_socket=DIR:/tmp/test)
189 * added support for EAP expanded type (vendor specific EAP methods)
191 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
192 * added experimental STAKey handshake implementation for IEEE 802.11e
193 direct link setup (DLS); note: this is disabled by default in both
194 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
196 * added support for EAP methods to use callbacks to external programs
197 by buffering a pending request and processing it after the EAP method
199 * improved EAP-SIM database interface to allow external request to GSM
200 HLR/AuC without blocking hostapd process
201 * added support for using EAP-SIM pseudonyms and fast re-authentication
202 * added support for EAP-AKA in the integrated EAP authenticator
203 * added support for matching EAP identity prefixes (e.g., "1"*) in EAP
204 user database to allow EAP-SIM/AKA selection without extra roundtrip
205 for EAP-Nak negotiation
206 * added support for storing EAP user password as NtPasswordHash instead
207 of plaintext password when using MSCHAP or MSCHAPv2 for
208 authentication (hash:<16-octet hex value>); added nt_password_hash
209 tool for hashing password to generate NtPasswordHash
211 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
212 * driver_wired: fixed EAPOL sending to optionally use PAE group address
213 as the destination instead of supplicant MAC address; this is
214 disabled by default, but should be enabled with use_pae_group_addr=1
215 in configuration file if the wired interface is used by only one
216 device at the time (common switch configuration)
217 * driver_madwifi: configure driver to use TKIP countermeasures in order
218 to get correct behavior (IEEE 802.11 association failing; previously,
219 association succeeded, but hostpad forced disassociation immediately)
220 * driver_madwifi: added support for madwifi-ng
223 * added support for replacing user identity from EAP with RADIUS
224 User-Name attribute from Access-Accept message, if that is included,
225 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
226 tunneled identity into accounting messages when the RADIUS server
227 does not support better way of doing this with Class attribute)
228 * driver_madwifi: fixed EAPOL packet receive for configuration where
229 ath# is part of a bridge interface
230 * added a configuration file and log analyzer script for logwatch
231 * fixed EAPOL state machine step function to process all state
232 transitions before processing new events; this resolves a race
233 condition in which EAPOL-Start message could trigger hostapd to send
234 two EAP-Response/Identity frames to the authentication server
237 * added client CA list to the TLS certificate request in order to make
238 it easier for the client to select which certificate to use
239 * added experimental support for EAP-PSK
240 * added support for WE-19 (hostap, madwifi)
243 * fixed build without CONFIG_RSN_PREAUTH
244 * fixed FreeBSD build
247 * fixed PMKSA caching to copy User-Name and Class attributes so that
248 RADIUS accounting gets correct information
249 * start RADIUS accounting only after successful completion of WPA
250 4-Way Handshake if WPA-PSK is used
251 * fixed PMKSA caching for the case where STA (re)associates without
255 * EAP-PAX is now registered as EAP type 46
256 * fixed EAP-PAX MAC calculation
257 * fixed EAP-PAX CK and ICK key derivation
258 * renamed eap_authenticator configuration variable to eap_server to
259 better match with RFC 3748 (EAP) terminology
260 * driver_test: added support for testing hostapd with wpa_supplicant
261 by using test driver interface without any kernel drivers or network
265 * fixed RADIUS server initialization when only auth or acct server
266 is configured and the other one is left empty
267 * driver_madwifi: added support for RADIUS accounting
268 * driver_madwifi: added preliminary support for compiling against 'BSD'
269 branch of madwifi CVS tree
270 * driver_madwifi: fixed pairwise key removal to allow WPA reauth
271 without disassociation
272 * added support for reading additional certificates from PKCS#12 files
273 and adding them to the certificate chain
274 * fixed RADIUS Class attribute processing to only use Access-Accept
275 packets to update Class; previously, other RADIUS authentication
276 packets could have cleared Class attribute
277 * added support for more than one Class attribute in RADIUS packets
278 * added support for verifying certificate revocation list (CRL) when
279 using integrated EAP authenticator for EAP-TLS; new hostapd.conf
280 options 'check_crl'; CRL must be included in the ca_cert file for now
282 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
283 * added support for including network information into
284 EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
285 (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
286 * fixed a bug which caused some RSN pre-authentication cases to use
287 freed memory and potentially crash hostapd
288 * fixed private key loading for cases where passphrase is not set
289 * added support for sending TLS alerts and aborting authentication
290 when receiving a TLS alert
291 * fixed WPA2 to add PMKSA cache entry when using integrated EAP
293 * fixed PMKSA caching (EAP authentication was not skipped correctly
294 with the new state machine changes from IEEE 802.1X draft)
295 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
296 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
297 to be added to .config to include IPv6 support); for RADIUS server,
298 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
299 in RADIUS clients file can then use IPv6 format
300 * added experimental support for EAP-PAX
301 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with
302 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
304 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
307 * added support for configuring a forced PEAP version based on the
309 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
310 to terminate authentication
311 * fixed EAP identifier duplicate processing with the new IEEE 802.1X
313 * clear accounting data in the driver when starting a new accounting
315 * driver_madwifi: filter wireless events based on ifindex to allow more
316 than one network interface to be used
317 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
318 setting if the packet does not pass MIC verification (e.g., due to
319 incorrect PSK); previously, message 1/4 was not tried again if an
320 invalid message 2/4 was received
321 * fixed reconfiguration of RADIUS client retransmission timer when
322 adding a new message to the pending list; previously, timer was not
323 updated at this point and if there was a pending message with long
324 time for the next retry, the new message needed to wait that long for
328 * added support for configuring multiple allowed EAP types for Phase 2
329 authentication (EAP-PEAP, EAP-TTLS)
330 * fixed EAPOL-Start processing to trigger WPA reauthentication
331 (previously, only EAPOL authentication was done)
334 * added support for EAP-PEAP in the integrated EAP authenticator
335 * added support for EAP-GTC in the integrated EAP authenticator
336 * added support for configuring list of EAP methods for Phase 1 so that
337 the integrated EAP authenticator can, e.g., use the wildcard entry
338 for EAP-TLS and EAP-PEAP
339 * added support for EAP-TTLS in the integrated EAP authenticator
340 * added support for EAP-SIM in the integrated EAP authenticator
341 * added support for using hostapd as a RADIUS authentication server
342 with the integrated EAP authenticator taking care of EAP
343 authentication (new hostapd.conf options: radius_server_clients and
344 radius_server_auth_port); this is not included in default build; use
345 CONFIG_RADIUS_SERVER=y in .config to include
348 * removed 'daemonize' configuration file option since it has not really
349 been used at all for more than year
350 * driver_madwifi: fixed group key setup and added get_ssid method
351 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator
354 * added support for integrated EAP-TLS authentication (new hostapd.conf
355 variables: ca_cert, server_cert, private_key, private_key_passwd);
356 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
357 external RADIUS server
358 * added support for reading PKCS#12 (PFX) files (as a replacement for
359 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
361 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
362 * added support for Acct-{Input,Output}-Gigawords
363 * added support for Event-Timestamp (in RADIUS Accounting-Requests)
364 * added support for RADIUS Authentication Client MIB (RFC2618)
365 * added support for RADIUS Accounting Client MIB (RFC2620)
366 * made EAP re-authentication period configurable (eap_reauth_period)
367 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
368 * fixed EAPOL state machine to stop if STA is removed during
369 eapol_sm_step(); this fixes at least one segfault triggering bug with
370 IEEE 802.11i pre-authentication
371 * added support for multiple WPA pre-shared keys (e.g., one for each
372 client MAC address or keys shared by a group of clients);
373 new hostapd.conf field wpa_psk_file for setting path to a text file
374 containing PSKs, see hostapd.wpa_psk for an example
375 * added support for multiple driver interfaces to allow hostapd to be
376 used with other drivers
377 * added wired authenticator driver interface (driver=wired in
378 hostapd.conf, see wired.conf for example configuration)
379 * added madwifi driver interface (driver=madwifi in hostapd.conf, see
380 madwifi.conf for example configuration; Note: include files from
381 madwifi project is needed for building and a configuration file,
382 .config, needs to be created in hostapd directory with
383 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
385 * fixed an alignment issue that could cause SHA-1 to fail on some
386 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
388 * fixed RADIUS reconnection after an error in sending interim
390 * added hostapd control interface for external programs and an example
391 CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
392 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
393 'hostapd_cli sta <addr>')
394 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
395 * added support for strict GTK rekeying (wpa_strict_rekey in
397 * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
398 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
400 * added Prism54 driver interface (driver=prism54 in hostapd.conf;
401 note: .config needs to be created in hostapd directory with
402 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
404 * dual-licensed hostapd (GPLv2 and BSD licenses)
405 * fixed RADIUS accounting to generate a new session id for cases where
406 a station reassociates without first being complete deauthenticated
407 * fixed STA disassociation handler to mark next timeout state to
408 deauthenticate the station, i.e., skip long wait for inactivity poll
409 and extra disassociation, if the STA disassociates without
411 * added integrated EAP authenticator that can be used instead of
412 external RADIUS authentication server; currently, only EAP-MD5 is
413 supported, so this cannot yet be used for key distribution; the EAP
414 method interface is generic, though, so adding new EAP methods should
415 be straightforward; new hostapd.conf variables: 'eap_authenticator'
416 and 'eap_user_file'; this obsoletes "minimal authentication server"
417 ('minimal_eap' in hostapd.conf) which is now removed
418 * added support for FreeBSD and driver interface for the BSD net80211
419 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
420 .config); please note that some of the required kernel mods have not
423 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
424 * fixed some accounting cases where Accounting-Start was sent when
425 IEEE 802.1X port was being deauthorized
428 * modified RADIUS client to re-connect the socket in case of certain
429 error codes that are generated when a network interface state is
430 changes (e.g., when IP address changes or the interface is set UP)
431 * fixed couple of cases where EAPOL state for a station was freed
432 twice causing a segfault for hostapd
433 * fixed couple of bugs in processing WPA deauthentication (freed data
437 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
438 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
439 cases where STAs dropped multicast frames as replay attacks
440 * added support for copying RADIUS Attribute 'Class' from
441 authentication messages into accounting messages
442 * send canned EAP failure if RADIUS server sends Access-Reject without
443 EAP message (previously, Supplicant was not notified in this case)
444 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
445 not start EAPOL state machines if the STA selected to use WPA-PSK)
448 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
449 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
450 (i.e., IEEE 802.11i/D3.0)
451 - supports WPA-only, RSN-only, and mixed WPA/RSN mode
452 - both WPA-PSK and WPA-RADIUS/EAP are supported
453 - PMKSA caching and pre-authentication
454 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
455 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
456 rsn_preauth, rsn_preauth_interfaces
457 * fixed interim accounting to remove any pending accounting messages
458 to the STA before sending a new one
461 * added support for Acct-Interim-Interval:
462 - draft-ietf-radius-acct-interim-01.txt
463 - use Acct-Interim-Interval attribute from Access-Accept if local
464 'radius_acct_interim_interval' is not set
465 - allow different update intervals for each STA
466 * fixed event loop to call signal handlers only after returning from
467 the real signal handler
468 * reset sta->timeout_next after successful association to make sure
469 that the previously registered inactivity timer will not remove the
470 STA immediately (e.g., if STA deauthenticates and re-associates
471 before the timer is triggered).
472 * added new hostapd.conf variable, nas_identifier, that can be used to
473 add an optional RADIUS Attribute, NAS-Identifier, into authentication
474 and accounting messages
475 * added support for Accounting-On and Accounting-Off messages
476 * fixed accounting session handling to send Accounting-Start only once
477 per session and not to send Accounting-Stop if the session was not
479 * fixed Accounting-Stop statistics in cases where the message was
480 previously sent after the kernel entry for the STA (and/or IEEE
481 802.1X data) was removed
486 Older changes up to and including v0.1.0 are included in the ChangeLog
487 of the Host AP driver.
