121 correctly; invalid messages could have caused the hostapd process to
122 terminate before this fix [CVE-2012-4445]
123 * limit number of active wildcard PINs for WPS Registrar to one to avoid
124 confusing behavior with multiple wildcard PINs

1342012-05-10 - v1.0
135 * Add channel selection support in hostapd. See hostapd.conf.
136 * Add support for IEEE 802.11v Time Advertisement mechanism with UTC
137 TSF offset. See hostapd.conf for config info.
138 * Delay STA entry removal until Deauth/Disassoc TX status in AP mode.
139 This allows the driver to use PS buffering of Deauthentication and
140 Disassociation frames when the STA is in power save sleep. Only
141 available with drivers that provide TX status events for Deauth/
142 Disassoc frames (nl80211).
143 * Allow PMKSA caching to be disabled on the Authenticator. See
144 hostap.conf config parameter disable_pmksa_caching.
145 * atheros: Add support for IEEE 802.11w configuration.
146 * bsd: Add support for setting HT values in IFM_MMASK.
147 * Allow client isolation to be configured with ap_isolate. Client
148 isolation can be used to prevent low-level bridging of frames
149 between associated stations in the BSS. By default, this bridging
150 is allowed.
151 * Allow coexistance of HT BSSes with WEP/TKIP BSSes.
152 * Add require_ht config parameter, which can be used to configure
153 hostapd to reject association with any station that does not support
154 HT PHY.
155 * Add support for writing debug log to a file using "-f" option. Also
156 add relog CLI command to re-open the log file.
157 * Add bridge handling for WDS STA interfaces. By default they are
158 added to the configured bridge of the AP interface (if present),
159 but the user can also specify a separate bridge using cli command
160 wds_bridge.
161 * hostapd_cli:
162 - Add wds_bridge command for specifying bridge for WDS STA
163 interfaces.
164 - Add relog command for reopening log file.
165 - Send AP-STA-DISCONNECTED event when an AP disconnects a station
166 due to inactivity.
167 - Add wps_config ctrl_interface command for configuring AP. This
168 command can be used to configure the AP using the internal WPS
169 registrar. It works in the same way as new AP settings received
170 from an ER.
171 - Many WPS/WPS ER commands - see WPS/WPS ER sections for details.
172 - Add command get version, that returns hostapd version string.
173 * WNM: Add BSS Transition Management Request for ESS Disassoc Imminent.
174 Use hostapd_cli ess_disassoc (STA addr) (URL) to send the
175 notification to the STA.
176 * Allow AP mode to disconnect STAs based on low ACK condition (when
177 the data connection is not working properly, e.g., due to the STA
178 going outside the range of the AP). Disabled by default, enable by
179 config option disassoc_low_ack.
180 * Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad
181 config file.
182 * WPS:
183 - Send AP Settings as a wrapped Credential attribute to ctrl_iface
185 - Dispatch more WPS events through hostapd ctrl_iface.
186 - Add mechanism for indicating non-standard WPS errors.
187 - Change concurrent radio AP to use only one WPS UPnP instance.
188 - Add wps_check_pin command for processing PIN from user input.
189 UIs can use this command to process a PIN entered by a user and to
190 validate the checksum digit (if present).
191 - Add hostap_cli get_config command to display current AP config.
192 - Add new hostapd_cli command, wps_ap_pin, to manage AP PIN at
193 runtime and support dynamic AP PIN management.
194 - Disable AP PIN after 10 consecutive failures. Slow down attacks
195 on failures up to 10.
196 - Allow AP to start in Enrollee mode without AP PIN for probing,
197 to be compatible with Windows 7.
198 - Add Config Error into WPS-FAIL events to provide more info
199 to the user on how to resolve the issue.
200 - When controlling multiple interfaces:
201 - apply WPS commands to all interfaces configured to use WPS
202 - apply WPS config changes to all interfaces that use WPS
203 - when an attack is detected on any interface, disable AP PIN on
204 all interfaces
205 * WPS ER:
206 - Show SetSelectedRegistrar events as ctrl_iface events.
207 - Add special AP Setup Locked mode to allow read only ER.
208 ap_setup_locked=2 can now be used to enable a special mode where
209 WPS ER can learn the current AP settings, but cannot change them.
210 * WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2)
211 - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool
212 for testing protocol extensibility.
213 - Add build option CONFIG_WPS_STRICT to allow disabling of WPS
214 workarounds.
215 - Add support for AuthorizedMACs attribute.
216 * TDLS:
217 - Allow TDLS use or TDLS channel switching in the BSS to be
218 prohibited in the BSS, using config params tdls_prohibit and
219 tdls_prohibit_chan_switch.
220 * EAP server: Add support for configuring fragment size (see
221 fragment_size in hostapd.conf).
222 * wlantest: Add a tool wlantest for IEEE802.11 protocol testing.
223 wlantest can be used to capture frames from a monitor interface
224 for realtime capturing or from pcap files for offline analysis.
225 * Interworking: Support added for 802.11u. Enable in .config with
226 CONFIG_INTERWORKING. See hostapd.conf for config parameters for
227 interworking.
228 * Android: Add build and runtime support for Android hostapd.
229 * Add a new debug message level for excessive information. Use
230 -ddd to enable.
231 * TLS: Add support for tls_disable_time_checks=1 in client mode.
232 * Internal TLS:
233 - Add support for TLS v1.1 (RFC 4346). Enable with build parameter
235 - Add domainComponent parser for X.509 names
236 * Reorder some IEs to get closer to IEEE 802.11 standard. Move
237 WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames.
238 Move HT IEs to be later in (Re)Assoc Resp.

249 compatibility with older wpa_supplicant/hostapd versions)
250 * cleaned up driver wrapper API for multi-BSS operations
251 * nl80211: fix multi-BSS and VLAN operations
252 * fix number of issues with IEEE 802.11r/FT; this version is not

260 implementations
261 * nl80211: fix WPS IE update
262 * hostapd_cli: add support for action script operations (run a script
263 on hostapd events)
264 * fix DH padding with internal crypto code (mainly, for WPS)
265 * fix WPS association with both WPS IE and WPA/RSN IE present with
266 driver wrappers that use hostapd MLME (e.g., nl80211)
2682010-01-16 - v0.7.1
269 * cleaned up driver wrapper API (struct wpa_driver_ops); the new API
270 is not fully backwards compatible, so out-of-tree driver wrappers
271 will need modifications
272 * cleaned up various module interfaces
273 * merge hostapd and wpa_supplicant developers' documentation into a
274 single document

282 * WPS: add support for dynamically selecting whether to provision the
283 PSK as an ASCII passphrase or PSK
284 * added support for WDS (4-address frame) mode with per-station virtual

287 * fixed WPS Probe Request processing to handle missing required
288 attribute
289 * fixed PKCS#12 use with OpenSSL 1.0.0
290 * detect bridge interface automatically so that bridge parameter in
291 hostapd.conf becomes optional (though, it may now be used to
292 automatically add then WLAN interface into a bridge with
293 driver=nl80211)
a875087d 294
2952009-11-21 - v0.7.0
296 * increased hostapd_cli ping interval to 5 seconds and made this
297 configurable with a new command line options (-G<seconds>)
298 * driver_nl80211: use Linux socket filter to improve performance
299 * added support for external Registrars with WPS (UPnP transport)
300 * 802.11n: scan for overlapping BSSes before starting 20/40 MHz channel
301 * driver_nl80211: fixed STA accounting data collection (TX/RX bytes

309 (note: this breaks interoperability with previous version) [Bug 303]
310 * fixed SHA-256 based key derivation function to match with the
311 standard when using CCMP (for IEEE 802.11r and IEEE 802.11w)
312 (note: this breaks interoperability with previous version) [Bug 307]
313 * added number of code size optimizations to remove unnecessary
314 functionality from the program binary based on build configuration
315 (part of this automatic; part configurable with CONFIG_NO_* build
316 options)
317 * use shared driver wrapper files with wpa_supplicant
318 * driver_nl80211: multiple updates to provide support for new Linux
319 nl80211/mac80211 functionality
320 * updated management frame protection to use IEEE Std 802.11w-2009
321 * fixed number of small WPS issues and added workarounds to
322 interoperate with common deployed broken implementations

327 * added preliminary support for IEEE 802.11r RIC processing
3292009-01-06 - v0.6.7
330 * added support for Wi-Fi Protected Setup (WPS)
331 (hostapd can now be configured to act as an integrated WPS Registrar
332 and provision credentials for WPS Enrollees using PIN and PBC
333 methods; external wireless Registrar can configure the AP, but
334 external WLAN Manager Registrars are not supported); WPS support can
335 be enabled by adding CONFIG_WPS=y into .config and setting the
336 runtime configuration variables in hostapd.conf (see WPS section in
337 the example configuration file); new hostapd_cli commands wps_pin and
338 wps_pbc are used to configure WPS negotiation; see README-WPS for
339 more details
340 * added IEEE 802.11n HT capability configuration (ht_capab)
341 * added support for generating Country IE based on nl80211 regulatory
342 information (added if ieee80211d=1 in configuration)
343 * fixed WEP authentication (both Open System and Shared Key) with
344 mac80211
345 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
346 * added support for using driver_test over UDP socket
347 * changed EAP-GPSK to use the IANA assigned EAP method type 51
348 * updated management frame protection to use IEEE 802.11w/D7.0
349 * fixed retransmission of EAP requests if no response is received
3512008-11-23 - v0.6.6
352 * added a new configuration option, wpa_ptk_rekey, that can be used to
353 enforce frequent PTK rekeying, e.g., to mitigate some attacks against
354 TKIP deficiencies
355 * updated OpenSSL code for EAP-FAST to use an updated version of the
356 session ticket overriding API that was included into the upstream
357 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
358 needed with that version anymore)
359 * changed channel flags configuration to read the information from
360 the driver (e.g., via driver_nl80211 when using mac80211) instead of
361 using hostapd as the source of the regulatory information (i.e.,
362 information from CRDA is now used with mac80211); this allows 5 GHz
363 channels to be used with hostapd (if allowed in the current
364 regulatory domain)
365 * fixed EAP-TLS message processing for the last TLS message if it is
366 large enough to require fragmentation (e.g., if a large Session
367 Ticket data is included)
368 * fixed listen interval configuration for nl80211 drivers
3702008-11-01 - v0.6.5
371 * added support for SHA-256 as X.509 certificate digest when using the
372 internal X.509/TLSv1 implementation
373 * fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer
374 identity lengths)
375 * fixed internal TLSv1 implementation for abbreviated handshake (used
376 by EAP-FAST server)
377 * added support for setting VLAN ID for STAs based on local MAC ACL
378 (accept_mac_file) as an alternative for RADIUS server-based
379 configuration
380 * updated management frame protection to use IEEE 802.11w/D6.0
381 (adds a new association ping to protect against unauthenticated
382 authenticate or (re)associate request frames dropping association)
383 * added support for using SHA256-based stronger key derivation for WPA2
384 (IEEE 802.11w)
385 * added new "driver wrapper" for RADIUS-only configuration
386 (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config)
387 * fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2)
388 is enabled in configuration
389 * changed EAP-FAST configuration to use separate fields for A-ID and
390 A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed
391 16-octet len binary value for better interoperability with some peer
392 implementations; eap_fast_a_id is now configured as a hex string
393 * driver_nl80211: Updated to match the current Linux mac80211 AP mode
394 configuration (wireless-testing.git and Linux kernel releases
395 starting from 2.6.29)
3972008-08-10 - v0.6.4
398 * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2
399 Identity Request if identity is already known
400 * added support for EAP Sequences in EAP-FAST Phase 2
401 * added support for EAP-TNC (Trusted Network Connect)
402 (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST
403 changes needed to run two methods in sequence (IF-T) and the IF-IMV
404 and IF-TNCCS interfaces from TNCS)
405 * added support for optional cryptobinding with PEAPv0
406 * added fragmentation support for EAP-TNC
407 * added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled)
408 data
409 * added support for opportunistic key caching (OKC)
4112008-02-22 - v0.6.3
412 * fixed Reassociation Response callback processing when using internal
413 MLME (driver_{hostap,nl80211,test}.c)
414 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
415 * copy optional Proxy-State attributes into RADIUS response when acting
416 as a RADIUS authentication server
417 * fixed EAPOL state machine to handle a case in which no response is
418 received from the RADIUS authentication server; previous version
419 could have triggered a crash in some cases after a timeout
420 * fixed EAP-SIM/AKA realm processing to allow decorated usernames to
421 be used
422 * added a workaround for EAP-SIM/AKA peers that include incorrect null
423 termination in the username
424 * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER
425 attribute in notification messages only when using fast
426 reauthentication
427 * fixed EAP-SIM Start response processing for fast reauthentication
428 case
429 * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST}
430 phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method
4322008-01-01 - v0.6.2
433 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
434 lengths properly to avoid potential crash caused by invalid messages
435 * added data structure for storing allocated buffers (struct wpabuf);
436 this does not affect hostapd usage, but many of the APIs changed
437 and various interfaces (e.g., EAP) is not compatible with old
438 versions
439 * added support for protecting EAP-AKA/Identity messages with
440 AT_CHECKCODE (optional feature in RFC 4187)
441 * added support for protected result indication with AT_RESULT_IND for
442 EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1)
443 * added support for configuring EAP-TTLS phase 2 non-EAP methods in
444 EAP server configuration; previously all four were enabled for every
445 phase 2 user, now all four are disabled by default and need to be
446 enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP,
448 * removed old debug printing mechanism and the related 'debug'
449 parameter in the configuration file; debug verbosity is now set with
450 -d (or -dd) command line arguments
451 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
452 only shared key/password authentication is supported in this version
4542007-11-24 - v0.6.1
455 * added experimental, integrated TLSv1 server implementation with the
456 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
457 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
458 .config); this can be useful, e.g., if the target system does not
459 have a suitable TLS library and a minimal code size is required
460 * added support for EAP-FAST server method to the integrated EAP
461 server
462 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
463 draft (draft-ietf-emu-eap-gpsk-07.txt)
464 * added a new configuration parameter, rsn_pairwise, to allow different
465 pairwise cipher suites to be enabled for WPA and RSN/WPA2
466 (note: if wpa_pairwise differs from rsn_pairwise, the driver will
467 either need to support this or will have to use the WPA/RSN IEs from
468 hostapd; currently, the included madwifi and bsd driver interfaces do
469 not have support for this)
470 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
4722007-05-28 - v0.6.0
473 * added experimental IEEE 802.11r/D6.0 support
474 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
475 * updated EAP-PSK to use the IANA-allocated EAP type 47
476 * fixed EAP-PSK bit ordering of the Flags field
477 * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
478 by reading wpa_psk_file [Bug 181]
479 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
480 * fixed IPv6 connection to RADIUS accounting server
481 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
482 draft (draft-ietf-emu-eap-gpsk-04.txt)
483 * hlr_auc_gw: read GSM triplet file into memory and rotate through the
484 entries instead of only using the same three triplets every time
485 (this does not work properly with tests using multiple clients, but
486 provides bit better triplet data for testing a single client; anyway,
487 if a better quality triplets are needed, GSM-Milenage should be used
488 instead of hardcoded triplet file)
489 * fixed EAP-MSCHAPv2 server to use a space between S and M parameters
490 in Success Request [Bug 203]
491 * added support for sending EAP-AKA Notifications in error cases
492 * updated to use IEEE 802.11w/D2.0 for management frame protection
493 (still experimental)
494 * RADIUS server: added support for processing duplicate messages
495 (retransmissions from RADIUS client) by replying with the previous
496 reply
4982006-11-24 - v0.5.6
499 * added support for configuring and controlling multiple BSSes per
500 radio interface (bss=<ifname> in hostapd.conf); this is only
501 available with Devicescape and test driver interfaces
502 * fixed PMKSA cache update in the end of successful RSN
503 pre-authentication
504 * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
505 for each STA based on RADIUS Access-Accept attributes); this requires
506 VLAN support from the kernel driver/802.11 stack and this is
507 currently only available with Devicescape and test driver interfaces
508 * driver_madwifi: fixed configuration of unencrypted modes (plaintext
509 and IEEE 802.1X without WEP)
510 * removed STAKey handshake since PeerKey handshake has replaced it in
511 IEEE 802.11ma and there are no known deployments of STAKey
512 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
513 draft (draft-ietf-emu-eap-gpsk-01.txt)
514 * added preliminary implementation of IEEE 802.11w/D1.0 (management
515 frame protection)
516 (Note: this requires driver support to work properly.)
517 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
518 * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
519 * hlr_auc_gw: added support for reading per-IMSI Milenage keys and
520 parameters from a text file to make it possible to implement proper
521 GSM/UMTS authentication server for multiple SIM/USIM cards using
523 * fixed session timeout processing with drivers that do not use
524 ieee802_11.c (e.g., madwifi)
5262006-08-27 - v0.5.5
527 * added 'hostapd_cli new_sta <addr>' command for adding a new STA into
528 hostapd (e.g., to initialize wired network authentication based on an
529 external signal)
530 * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
531 using WPA2 even if PMKSA caching is not used
532 * added -P<pid file> argument for hostapd to write the current process
533 id into a file
534 * added support for RADIUS Authentication Server MIB (RFC 2619)
5362006-06-20 - v0.5.4
537 * fixed nt_password_hash build [Bug 144]
538 * added PeerKey handshake implementation for IEEE 802.11e
539 direct link setup (DLS) to replace STAKey handshake
540 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
541 draft-clancy-emu-eap-shared-secret-00.txt)
542 * fixed a segmentation fault when RSN pre-authentication was completed
543 successfully [Bug 152]
5452006-04-27 - v0.5.3
546 * do not build nt_password_hash and hlr_auc_gw by default to avoid
547 requiring a TLS library for a successful build; these programs can be
548 build with 'make nt_password_hash' and 'make hlr_auc_gw'
549 * added a new configuration option, eapol_version, that can be used to
550 set EAPOL version to 1 (default is 2) to work around broken client
551 implementations that drop EAPOL frames which use version number 2
552 [Bug 89]
553 * added support for EAP-SAKE (no EAP method number allocated yet, so
554 this is using the same experimental type 255 as EAP-PSK)
555 * fixed EAP-MSCHAPv2 message length validation
5572006-03-19 - v0.5.2
558 * fixed stdarg use in hostapd_logger(): if both stdout and syslog
559 logging was enabled, hostapd could trigger a segmentation fault in
560 vsyslog on some CPU -- C library combinations
561 * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
562 program to make it easier to use for implementing real SS7 gateway;
563 eap_sim_db is not anymore used as a file name for GSM authentication
564 triplets; instead, it is path to UNIX domain socket that will be used
565 to communicate with the external gateway program (e.g., hlr_auc_gw)
566 * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
567 local information (GSM authentication triplets from a text file and
568 hardcoded AKA authentication data); this can be used to test EAP-SIM
569 and EAP-AKA
570 * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
571 to make it possible to test EAP-AKA with real USIM cards (this is
572 disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
573 to enable this)
574 * driver_madwifi: added support for getting station RSN IE from
575 madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
576 broken with earlier change (r1357) in the driver
577 * changed EAP method registration to use a dynamic list of methods
578 instead of a static list generated at build time
579 * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
580 [Bug 125]
581 * added ap_max_inactivity configuration parameter
5832006-01-29 - v0.5.1
584 * driver_test: added better support for multiple APs and STAs by using
585 a directory with sockets that include MAC address for each device in
586 the name (test_socket=DIR:/tmp/test)
587 * added support for EAP expanded type (vendor specific EAP methods)
5892005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
590 * added experimental STAKey handshake implementation for IEEE 802.11e
591 direct link setup (DLS); note: this is disabled by default in both
592 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
593 and stakey=1)
594 * added support for EAP methods to use callbacks to external programs
595 by buffering a pending request and processing it after the EAP method
596 is ready to continue
597 * improved EAP-SIM database interface to allow external request to GSM
598 HLR/AuC without blocking hostapd process
599 * added support for using EAP-SIM pseudonyms and fast re-authentication
600 * added support for EAP-AKA in the integrated EAP authenticator
601 * added support for matching EAP identity prefixes (e.g., "1"*) in EAP
602 user database to allow EAP-SIM/AKA selection without extra roundtrip
603 for EAP-Nak negotiation
604 * added support for storing EAP user password as NtPasswordHash instead
605 of plaintext password when using MSCHAP or MSCHAPv2 for
606 authentication (hash:<16-octet hex value>); added nt_password_hash
607 tool for hashing password to generate NtPasswordHash
6092005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
610 * driver_wired: fixed EAPOL sending to optionally use PAE group address
611 as the destination instead of supplicant MAC address; this is
612 disabled by default, but should be enabled with use_pae_group_addr=1
613 in configuration file if the wired interface is used by only one
614 device at the time (common switch configuration)
615 * driver_madwifi: configure driver to use TKIP countermeasures in order
616 to get correct behavior (IEEE 802.11 association failing; previously,
617 association succeeded, but hostpad forced disassociation immediately)
618 * driver_madwifi: added support for madwifi-ng
6202005-10-27 - v0.4.6
621 * added support for replacing user identity from EAP with RADIUS
622 User-Name attribute from Access-Accept message, if that is included,
623 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
624 tunneled identity into accounting messages when the RADIUS server
625 does not support better way of doing this with Class attribute)
626 * driver_madwifi: fixed EAPOL packet receive for configuration where
627 ath# is part of a bridge interface
628 * added a configuration file and log analyzer script for logwatch
629 * fixed EAPOL state machine step function to process all state
630 transitions before processing new events; this resolves a race
631 condition in which EAPOL-Start message could trigger hostapd to send
632 two EAP-Response/Identity frames to the authentication server
6342005-09-25 - v0.4.5
635 * added client CA list to the TLS certificate request in order to make
636 it easier for the client to select which certificate to use
637 * added experimental support for EAP-PSK
638 * added support for WE-19 (hostap, madwifi)
6402005-08-21 - v0.4.4
641 * fixed build without CONFIG_RSN_PREAUTH
642 * fixed FreeBSD build
6442005-06-26 - v0.4.3
645 * fixed PMKSA caching to copy User-Name and Class attributes so that
646 RADIUS accounting gets correct information
647 * start RADIUS accounting only after successful completion of WPA
648 4-Way Handshake if WPA-PSK is used
649 * fixed PMKSA caching for the case where STA (re)associates without
650 first disassociating
6522005-06-12 - v0.4.2
653 * EAP-PAX is now registered as EAP type 46
654 * fixed EAP-PAX MAC calculation
655 * fixed EAP-PAX CK and ICK key derivation
656 * renamed eap_authenticator configuration variable to eap_server to
657 better match with RFC 3748 (EAP) terminology
658 * driver_test: added support for testing hostapd with wpa_supplicant
659 by using test driver interface without any kernel drivers or network
660 cards
6622005-05-22 - v0.4.1
663 * fixed RADIUS server initialization when only auth or acct server
664 is configured and the other one is left empty
665 * driver_madwifi: added support for RADIUS accounting
666 * driver_madwifi: added preliminary support for compiling against 'BSD'
667 branch of madwifi CVS tree
668 * driver_madwifi: fixed pairwise key removal to allow WPA reauth
669 without disassociation
670 * added support for reading additional certificates from PKCS#12 files
671 and adding them to the certificate chain
672 * fixed RADIUS Class attribute processing to only use Access-Accept
673 packets to update Class; previously, other RADIUS authentication
674 packets could have cleared Class attribute
675 * added support for more than one Class attribute in RADIUS packets
676 * added support for verifying certificate revocation list (CRL) when
677 using integrated EAP authenticator for EAP-TLS; new hostapd.conf
678 options 'check_crl'; CRL must be included in the ca_cert file for now
6802005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
681 * added support for including network information into
682 EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
683 (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
684 * fixed a bug which caused some RSN pre-authentication cases to use
685 freed memory and potentially crash hostapd
686 * fixed private key loading for cases where passphrase is not set
687 * added support for sending TLS alerts and aborting authentication
688 when receiving a TLS alert
689 * fixed WPA2 to add PMKSA cache entry when using integrated EAP
690 authenticator
691 * fixed PMKSA caching (EAP authentication was not skipped correctly
692 with the new state machine changes from IEEE 802.1X draft)
693 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
694 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
695 to be added to .config to include IPv6 support); for RADIUS server,
696 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
697 in RADIUS clients file can then use IPv6 format
698 * added experimental support for EAP-PAX
699 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with
700 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
7022005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
7042005-01-23 - v0.3.5
705 * added support for configuring a forced PEAP version based on the
706 Phase 1 identity
707 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
708 to terminate authentication
709 * fixed EAP identifier duplicate processing with the new IEEE 802.1X
710 draft
711 * clear accounting data in the driver when starting a new accounting
712 session
713 * driver_madwifi: filter wireless events based on ifindex to allow more
714 than one network interface to be used
715 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
716 setting if the packet does not pass MIC verification (e.g., due to
717 incorrect PSK); previously, message 1/4 was not tried again if an
718 invalid message 2/4 was received
719 * fixed reconfiguration of RADIUS client retransmission timer when
720 adding a new message to the pending list; previously, timer was not
721 updated at this point and if there was a pending message with long
722 time for the next retry, the new message needed to wait that long for
723 its first retry, too
7252005-01-09 - v0.3.4
726 * added support for configuring multiple allowed EAP types for Phase 2
727 authentication (EAP-PEAP, EAP-TTLS)
728 * fixed EAPOL-Start processing to trigger WPA reauthentication
729 (previously, only EAPOL authentication was done)
7312005-01-02 - v0.3.3
732 * added support for EAP-PEAP in the integrated EAP authenticator
733 * added support for EAP-GTC in the integrated EAP authenticator
734 * added support for configuring list of EAP methods for Phase 1 so that
735 the integrated EAP authenticator can, e.g., use the wildcard entry
736 for EAP-TLS and EAP-PEAP
737 * added support for EAP-TTLS in the integrated EAP authenticator
738 * added support for EAP-SIM in the integrated EAP authenticator
739 * added support for using hostapd as a RADIUS authentication server
740 with the integrated EAP authenticator taking care of EAP
741 authentication (new hostapd.conf options: radius_server_clients and
742 radius_server_auth_port); this is not included in default build; use
743 CONFIG_RADIUS_SERVER=y in .config to include
7452004-12-19 - v0.3.2
746 * removed 'daemonize' configuration file option since it has not really
747 been used at all for more than year
748 * driver_madwifi: fixed group key setup and added get_ssid method
749 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator
7512004-12-12 - v0.3.1
752 * added support for integrated EAP-TLS authentication (new hostapd.conf
753 variables: ca_cert, server_cert, private_key, private_key_passwd);
754 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
755 external RADIUS server
756 * added support for reading PKCS#12 (PFX) files (as a replacement for
757 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
7592004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
760 * added support for Acct-{Input,Output}-Gigawords
761 * added support for Event-Timestamp (in RADIUS Accounting-Requests)
762 * added support for RADIUS Authentication Client MIB (RFC2618)
763 * added support for RADIUS Accounting Client MIB (RFC2620)
764 * made EAP re-authentication period configurable (eap_reauth_period)
765 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
766 * fixed EAPOL state machine to stop if STA is removed during
767 eapol_sm_step(); this fixes at least one segfault triggering bug with
768 IEEE 802.11i pre-authentication
769 * added support for multiple WPA pre-shared keys (e.g., one for each
770 client MAC address or keys shared by a group of clients);
771 new hostapd.conf field wpa_psk_file for setting path to a text file
772 containing PSKs, see hostapd.wpa_psk for an example
773 * added support for multiple driver interfaces to allow hostapd to be
774 used with other drivers
775 * added wired authenticator driver interface (driver=wired in
776 hostapd.conf, see wired.conf for example configuration)
777 * added madwifi driver interface (driver=madwifi in hostapd.conf, see
778 madwifi.conf for example configuration; Note: include files from
779 madwifi project is needed for building and a configuration file,
780 .config, needs to be created in hostapd directory with
781 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
782 build)
783 * fixed an alignment issue that could cause SHA-1 to fail on some
784 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
785 align variables)
786 * fixed RADIUS reconnection after an error in sending interim
787 accounting packets
788 * added hostapd control interface for external programs and an example
789 CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
790 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
791 'hostapd_cli sta <addr>')
792 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
793 * added support for strict GTK rekeying (wpa_strict_rekey in
794 hostapd.conf)
795 * updated IAPP to use UDP port 3517 and multicast address
796 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
797 IEEE 802.11F-2003)
798 * added Prism54 driver interface (driver=prism54 in hostapd.conf;
799 note: .config needs to be created in hostapd directory with
800 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
801 build)
802 * dual-licensed hostapd (GPLv2 and BSD licenses)
803 * fixed RADIUS accounting to generate a new session id for cases where
804 a station reassociates without first being complete deauthenticated
805 * fixed STA disassociation handler to mark next timeout state to
806 deauthenticate the station, i.e., skip long wait for inactivity poll
807 and extra disassociation, if the STA disassociates without
808 deauthenticating
809 * added integrated EAP authenticator that can be used instead of
810 external RADIUS authentication server; currently, only EAP-MD5 is
811 supported, so this cannot yet be used for key distribution; the EAP
812 method interface is generic, though, so adding new EAP methods should
813 be straightforward; new hostapd.conf variables: 'eap_authenticator'
814 and 'eap_user_file'; this obsoletes "minimal authentication server"
815 ('minimal_eap' in hostapd.conf) which is now removed
816 * added support for FreeBSD and driver interface for the BSD net80211
817 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
818 .config); please note that some of the required kernel mods have not
819 yet been committed
8212004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
822 * fixed some accounting cases where Accounting-Start was sent when
823 IEEE 802.1X port was being deauthorized
8252004-06-20 - v0.2.3
826 * modified RADIUS client to re-connect the socket in case of certain
827 error codes that are generated when a network interface state is
828 changes (e.g., when IP address changes or the interface is set UP)
829 * fixed couple of cases where EAPOL state for a station was freed
830 twice causing a segfault for hostapd
831 * fixed couple of bugs in processing WPA deauthentication (freed data
832 was used)
8342004-05-31 - v0.2.2
835 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
836 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
837 cases where STAs dropped multicast frames as replay attacks
838 * added support for copying RADIUS Attribute 'Class' from
839 authentication messages into accounting messages
840 * send canned EAP failure if RADIUS server sends Access-Reject without
841 EAP message (previously, Supplicant was not notified in this case)
842 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
843 not start EAPOL state machines if the STA selected to use WPA-PSK)
8452004-05-06 - v0.2.1
846 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
847 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
848 (i.e., IEEE 802.11i/D3.0)
849 - supports WPA-only, RSN-only, and mixed WPA/RSN mode
850 - both WPA-PSK and WPA-RADIUS/EAP are supported
851 - PMKSA caching and pre-authentication
852 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
853 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
854 rsn_preauth, rsn_preauth_interfaces
855 * fixed interim accounting to remove any pending accounting messages
856 to the STA before sending a new one
8582004-02-15 - v0.2.0
859 * added support for Acct-Interim-Interval:
860 - draft-ietf-radius-acct-interim-01.txt
861 - use Acct-Interim-Interval attribute from Access-Accept if local
862 'radius_acct_interim_interval' is not set
863 - allow different update intervals for each STA
864 * fixed event loop to call signal handlers only after returning from
865 the real signal handler
866 * reset sta->timeout_next after successful association to make sure
867 that the previously registered inactivity timer will not remove the
868 STA immediately (e.g., if STA deauthenticates and re-associates
869 before the timer is triggered).
870 * added new hostapd.conf variable, nas_identifier, that can be used to
871 add an optional RADIUS Attribute, NAS-Identifier, into authentication
872 and accounting messages
873 * added support for Accounting-On and Accounting-Off messages
874 * fixed accounting session handling to send Accounting-Start only once
875 per session and not to send Accounting-Stop if the session was not
876 initialized properly
877 * fixed Accounting-Stop statistics in cases where the message was
878 previously sent after the kernel entry for the STA (and/or IEEE
879 802.1X data) was removed
884Older changes up to and including v0.1.0 are included in the ChangeLog
885of the Host AP driver.
