140 - Add command get version, that returns hostapd version string.
141 * WNM: Add BSS Transition Management Request for ESS Disassoc Imminent.
142 Use hostapd_cli ess_disassoc (STA addr) (URL) to send the
143 notification to the STA.
144 * Allow AP mode to disconnect STAs based on low ACK condition (when
145 the data connection is not working properly, e.g., due to the STA
146 going outside the range of the AP). Disabled by default, enable by
147 config option disassoc_low_ack.

278 * fixed SHA-256 based key derivation function to match with the
279 standard when using CCMP (for IEEE 802.11r and IEEE 802.11w)
280 (note: this breaks interoperability with previous version) [Bug 307]
281 * added number of code size optimizations to remove unnecessary

295 * added preliminary support for IEEE 802.11r RIC processing
298 * added support for Wi-Fi Protected Setup (WPS)
299 (hostapd can now be configured to act as an integrated WPS Registrar
300 and provision credentials for WPS Enrollees using PIN and PBC
301 methods; external wireless Registrar can configure the AP, but
302 external WLAN Manager Registrars are not supported); WPS support can
303 be enabled by adding CONFIG_WPS=y into .config and setting the
304 runtime configuration variables in hostapd.conf (see WPS section in
305 the example configuration file); new hostapd_cli commands wps_pin and
306 wps_pbc are used to configure WPS negotiation; see README-WPS for
308 * added IEEE 802.11n HT capability configuration (ht_capab)
309 * added support for generating Country IE based on nl80211 regulatory

320 * added a new configuration option, wpa_ptk_rekey, that can be used to
321 enforce frequent PTK rekeying, e.g., to mitigate some attacks against
323 * updated OpenSSL code for EAP-FAST to use an updated version of the
324 session ticket overriding API that was included into the upstream
325 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
326 needed with that version anymore)
327 * changed channel flags configuration to read the information from
328 the driver (e.g., via driver_nl80211 when using mac80211) instead of
329 using hostapd as the source of the regulatory information (i.e.,
330 information from CRDA is now used with mac80211); this allows 5 GHz
331 channels to be used with hostapd (if allowed in the current
333 * fixed EAP-TLS message processing for the last TLS message if it is
334 large enough to require fragmentation (e.g., if a large Session
335 Ticket data is included)
336 * fixed listen interval configuration for nl80211 drivers

350 authenticate or (re)associate request frames dropping association)
351 * added support for using SHA256-based stronger key derivation for WPA2
353 * added new "driver wrapper" for RADIUS-only configuration
354 (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config)
355 * fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2)
356 is enabled in configuration
357 * changed EAP-FAST configuration to use separate fields for A-ID and
358 A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed
359 16-octet len binary value for better interoperability with some peer
360 implementations; eap_fast_a_id is now configured as a hex string
361 * driver_nl80211: Updated to match the current Linux mac80211 AP mode
362 configuration (wireless-testing.git and Linux kernel releases
363 starting from 2.6.29)
366 * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2
367 Identity Request if identity is already known
368 * added support for EAP Sequences in EAP-FAST Phase 2

372 and IF-TNCCS interfaces from TNCS)
373 * added support for optional cryptobinding with PEAPv0

383 * copy optional Proxy-State attributes into RADIUS response when acting
384 as a RADIUS authentication server
385 * fixed EAPOL state machine to handle a case in which no response is
386 received from the RADIUS authentication server; previous version
387 could have triggered a crash in some cases after a timeout
388 * fixed EAP-SIM/AKA realm processing to allow decorated usernames to
390 * added a workaround for EAP-SIM/AKA peers that include incorrect null
391 termination in the username

393 attribute in notification messages only when using fast
395 * fixed EAP-SIM Start response processing for fast reauthentication
397 * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST}
398 phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method
401 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
402 lengths properly to avoid potential crash caused by invalid messages
403 * added data structure for storing allocated buffers (struct wpabuf);
404 this does not affect hostapd usage, but many of the APIs changed
405 and various interfaces (e.g., EAP) is not compatible with old
407 * added support for protecting EAP-AKA/Identity messages with
408 AT_CHECKCODE (optional feature in RFC 4187)
409 * added support for protected result indication with AT_RESULT_IND for
410 EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1)
411 * added support for configuring EAP-TTLS phase 2 non-EAP methods in
412 EAP server configuration; previously all four were enabled for every
413 phase 2 user, now all four are disabled by default and need to be
414 enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP,
416 * removed old debug printing mechanism and the related 'debug'
417 parameter in the configuration file; debug verbosity is now set with
418 -d (or -dd) command line arguments
419 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
420 only shared key/password authentication is supported in this version
423 * added experimental, integrated TLSv1 server implementation with the
424 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
425 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
426 .config); this can be useful, e.g., if the target system does not
427 have a suitable TLS library and a minimal code size is required
428 * added support for EAP-FAST server method to the integrated EAP
430 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
431 draft (draft-ietf-emu-eap-gpsk-07.txt)
432 * added a new configuration parameter, rsn_pairwise, to allow different
433 pairwise cipher suites to be enabled for WPA and RSN/WPA2
434 (note: if wpa_pairwise differs from rsn_pairwise, the driver will
435 either need to support this or will have to use the WPA/RSN IEs from
436 hostapd; currently, the included madwifi and bsd driver interfaces do
437 not have support for this)
438 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
441 * added experimental IEEE 802.11r/D6.0 support
442 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
443 * updated EAP-PSK to use the IANA-allocated EAP type 47

445 * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
446 by reading wpa_psk_file [Bug 181]
447 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
448 * fixed IPv6 connection to RADIUS accounting server
449 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
450 draft (draft-ietf-emu-eap-gpsk-04.txt)
451 * hlr_auc_gw: read GSM triplet file into memory and rotate through the
452 entries instead of only using the same three triplets every time
453 (this does not work properly with tests using multiple clients, but
454 provides bit better triplet data for testing a single client; anyway,
455 if a better quality triplets are needed, GSM-Milenage should be used
456 instead of hardcoded triplet file)
457 * fixed EAP-MSCHAPv2 server to use a space between S and M parameters
458 in Success Request [Bug 203]
459 * added support for sending EAP-AKA Notifications in error cases
460 * updated to use IEEE 802.11w/D2.0 for management frame protection
462 * RADIUS server: added support for processing duplicate messages
463 (retransmissions from RADIUS client) by replying with the previous
467 * added support for configuring and controlling multiple BSSes per
468 radio interface (bss=<ifname> in hostapd.conf); this is only
469 available with Devicescape and test driver interfaces
470 * fixed PMKSA cache update in the end of successful RSN
472 * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
473 for each STA based on RADIUS Access-Accept attributes); this requires
474 VLAN support from the kernel driver/802.11 stack and this is
475 currently only available with Devicescape and test driver interfaces
476 * driver_madwifi: fixed configuration of unencrypted modes (plaintext
477 and IEEE 802.1X without WEP)
478 * removed STAKey handshake since PeerKey handshake has replaced it in
479 IEEE 802.11ma and there are no known deployments of STAKey
480 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
481 draft (draft-ietf-emu-eap-gpsk-01.txt)
482 * added preliminary implementation of IEEE 802.11w/D1.0 (management
484 (Note: this requires driver support to work properly.)
485 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
486 * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
487 * hlr_auc_gw: added support for reading per-IMSI Milenage keys and
488 parameters from a text file to make it possible to implement proper
489 GSM/UMTS authentication server for multiple SIM/USIM cards using
491 * fixed session timeout processing with drivers that do not use
492 ieee802_11.c (e.g., madwifi)
495 * added 'hostapd_cli new_sta <addr>' command for adding a new STA into
496 hostapd (e.g., to initialize wired network authentication based on an
498 * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
499 using WPA2 even if PMKSA caching is not used
500 * added -P<pid file> argument for hostapd to write the current process
502 * added support for RADIUS Authentication Server MIB (RFC 2619)
505 * fixed nt_password_hash build [Bug 144]
506 * added PeerKey handshake implementation for IEEE 802.11e
507 direct link setup (DLS) to replace STAKey handshake
508 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
509 draft-clancy-emu-eap-shared-secret-00.txt)
510 * fixed a segmentation fault when RSN pre-authentication was completed
511 successfully [Bug 152]
514 * do not build nt_password_hash and hlr_auc_gw by default to avoid
515 requiring a TLS library for a successful build; these programs can be
516 build with 'make nt_password_hash' and 'make hlr_auc_gw'
517 * added a new configuration option, eapol_version, that can be used to
518 set EAPOL version to 1 (default is 2) to work around broken client
519 implementations that drop EAPOL frames which use version number 2
521 * added support for EAP-SAKE (no EAP method number allocated yet, so
522 this is using the same experimental type 255 as EAP-PSK)
523 * fixed EAP-MSCHAPv2 message length validation
526 * fixed stdarg use in hostapd_logger(): if both stdout and syslog
527 logging was enabled, hostapd could trigger a segmentation fault in
528 vsyslog on some CPU -- C library combinations
529 * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
530 program to make it easier to use for implementing real SS7 gateway;
531 eap_sim_db is not anymore used as a file name for GSM authentication
532 triplets; instead, it is path to UNIX domain socket that will be used
533 to communicate with the external gateway program (e.g., hlr_auc_gw)
534 * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
535 local information (GSM authentication triplets from a text file and
536 hardcoded AKA authentication data); this can be used to test EAP-SIM
538 * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
539 to make it possible to test EAP-AKA with real USIM cards (this is
540 disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
542 * driver_madwifi: added support for getting station RSN IE from
543 madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
544 broken with earlier change (r1357) in the driver
545 * changed EAP method registration to use a dynamic list of methods
546 instead of a static list generated at build time
547 * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
549 * added ap_max_inactivity configuration parameter
552 * driver_test: added better support for multiple APs and STAs by using
553 a directory with sockets that include MAC address for each device in
554 the name (test_socket=DIR:/tmp/test)
555 * added support for EAP expanded type (vendor specific EAP methods)
557 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
558 * added experimental STAKey handshake implementation for IEEE 802.11e
559 direct link setup (DLS); note: this is disabled by default in both
560 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
562 * added support for EAP methods to use callbacks to external programs
563 by buffering a pending request and processing it after the EAP method
565 * improved EAP-SIM database interface to allow external request to GSM
566 HLR/AuC without blocking hostapd process
567 * added support for using EAP-SIM pseudonyms and fast re-authentication
568 * added support for EAP-AKA in the integrated EAP authenticator
569 * added support for matching EAP identity prefixes (e.g., "1"*) in EAP
570 user database to allow EAP-SIM/AKA selection without extra roundtrip
571 for EAP-Nak negotiation
572 * added support for storing EAP user password as NtPasswordHash instead
573 of plaintext password when using MSCHAP or MSCHAPv2 for
574 authentication (hash:<16-octet hex value>); added nt_password_hash
575 tool for hashing password to generate NtPasswordHash
577 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
578 * driver_wired: fixed EAPOL sending to optionally use PAE group address
579 as the destination instead of supplicant MAC address; this is
580 disabled by default, but should be enabled with use_pae_group_addr=1
581 in configuration file if the wired interface is used by only one
582 device at the time (common switch configuration)
583 * driver_madwifi: configure driver to use TKIP countermeasures in order
584 to get correct behavior (IEEE 802.11 association failing; previously,
585 association succeeded, but hostpad forced disassociation immediately)
586 * driver_madwifi: added support for madwifi-ng
589 * added support for replacing user identity from EAP with RADIUS
590 User-Name attribute from Access-Accept message, if that is included,
591 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
592 tunneled identity into accounting messages when the RADIUS server
593 does not support better way of doing this with Class attribute)
594 * driver_madwifi: fixed EAPOL packet receive for configuration where
595 ath# is part of a bridge interface
596 * added a configuration file and log analyzer script for logwatch
597 * fixed EAPOL state machine step function to process all state
598 transitions before processing new events; this resolves a race
599 condition in which EAPOL-Start message could trigger hostapd to send
600 two EAP-Response/Identity frames to the authentication server
603 * added client CA list to the TLS certificate request in order to make
604 it easier for the client to select which certificate to use
605 * added experimental support for EAP-PSK
606 * added support for WE-19 (hostap, madwifi)
609 * fixed build without CONFIG_RSN_PREAUTH
610 * fixed FreeBSD build
613 * fixed PMKSA caching to copy User-Name and Class attributes so that
614 RADIUS accounting gets correct information
615 * start RADIUS accounting only after successful completion of WPA
616 4-Way Handshake if WPA-PSK is used
617 * fixed PMKSA caching for the case where STA (re)associates without
621 * EAP-PAX is now registered as EAP type 46
622 * fixed EAP-PAX MAC calculation
623 * fixed EAP-PAX CK and ICK key derivation
624 * renamed eap_authenticator configuration variable to eap_server to
625 better match with RFC 3748 (EAP) terminology
626 * driver_test: added support for testing hostapd with wpa_supplicant
627 by using test driver interface without any kernel drivers or network
631 * fixed RADIUS server initialization when only auth or acct server
632 is configured and the other one is left empty
633 * driver_madwifi: added support for RADIUS accounting
634 * driver_madwifi: added preliminary support for compiling against 'BSD'
635 branch of madwifi CVS tree
636 * driver_madwifi: fixed pairwise key removal to allow WPA reauth
637 without disassociation
638 * added support for reading additional certificates from PKCS#12 files
639 and adding them to the certificate chain
640 * fixed RADIUS Class attribute processing to only use Access-Accept
641 packets to update Class; previously, other RADIUS authentication
642 packets could have cleared Class attribute
643 * added support for more than one Class attribute in RADIUS packets
644 * added support for verifying certificate revocation list (CRL) when
645 using integrated EAP authenticator for EAP-TLS; new hostapd.conf
646 options 'check_crl'; CRL must be included in the ca_cert file for now
648 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
649 * added support for including network information into
650 EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
651 (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
652 * fixed a bug which caused some RSN pre-authentication cases to use
653 freed memory and potentially crash hostapd
654 * fixed private key loading for cases where passphrase is not set
655 * added support for sending TLS alerts and aborting authentication
656 when receiving a TLS alert
657 * fixed WPA2 to add PMKSA cache entry when using integrated EAP
659 * fixed PMKSA caching (EAP authentication was not skipped correctly
660 with the new state machine changes from IEEE 802.1X draft)
661 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
662 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
663 to be added to .config to include IPv6 support); for RADIUS server,
664 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
665 in RADIUS clients file can then use IPv6 format
666 * added experimental support for EAP-PAX
667 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with
668 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
670 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
673 * added support for configuring a forced PEAP version based on the
675 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
676 to terminate authentication
677 * fixed EAP identifier duplicate processing with the new IEEE 802.1X
679 * clear accounting data in the driver when starting a new accounting
681 * driver_madwifi: filter wireless events based on ifindex to allow more
682 than one network interface to be used
683 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
684 setting if the packet does not pass MIC verification (e.g., due to
685 incorrect PSK); previously, message 1/4 was not tried again if an
686 invalid message 2/4 was received
687 * fixed reconfiguration of RADIUS client retransmission timer when
688 adding a new message to the pending list; previously, timer was not
689 updated at this point and if there was a pending message with long
690 time for the next retry, the new message needed to wait that long for
694 * added support for configuring multiple allowed EAP types for Phase 2
695 authentication (EAP-PEAP, EAP-TTLS)
696 * fixed EAPOL-Start processing to trigger WPA reauthentication
697 (previously, only EAPOL authentication was done)
700 * added support for EAP-PEAP in the integrated EAP authenticator
701 * added support for EAP-GTC in the integrated EAP authenticator
702 * added support for configuring list of EAP methods for Phase 1 so that
703 the integrated EAP authenticator can, e.g., use the wildcard entry
704 for EAP-TLS and EAP-PEAP
705 * added support for EAP-TTLS in the integrated EAP authenticator
706 * added support for EAP-SIM in the integrated EAP authenticator
707 * added support for using hostapd as a RADIUS authentication server
708 with the integrated EAP authenticator taking care of EAP
709 authentication (new hostapd.conf options: radius_server_clients and
710 radius_server_auth_port); this is not included in default build; use
711 CONFIG_RADIUS_SERVER=y in .config to include
714 * removed 'daemonize' configuration file option since it has not really
715 been used at all for more than year
716 * driver_madwifi: fixed group key setup and added get_ssid method
717 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator
720 * added support for integrated EAP-TLS authentication (new hostapd.conf
721 variables: ca_cert, server_cert, private_key, private_key_passwd);
722 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
723 external RADIUS server
724 * added support for reading PKCS#12 (PFX) files (as a replacement for
725 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
727 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
728 * added support for Acct-{Input,Output}-Gigawords
729 * added support for Event-Timestamp (in RADIUS Accounting-Requests)
730 * added support for RADIUS Authentication Client MIB (RFC2618)
731 * added support for RADIUS Accounting Client MIB (RFC2620)
732 * made EAP re-authentication period configurable (eap_reauth_period)
733 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
734 * fixed EAPOL state machine to stop if STA is removed during
735 eapol_sm_step(); this fixes at least one segfault triggering bug with
736 IEEE 802.11i pre-authentication
737 * added support for multiple WPA pre-shared keys (e.g., one for each
738 client MAC address or keys shared by a group of clients);
739 new hostapd.conf field wpa_psk_file for setting path to a text file
740 containing PSKs, see hostapd.wpa_psk for an example
741 * added support for multiple driver interfaces to allow hostapd to be
742 used with other drivers
743 * added wired authenticator driver interface (driver=wired in
744 hostapd.conf, see wired.conf for example configuration)
745 * added madwifi driver interface (driver=madwifi in hostapd.conf, see
746 madwifi.conf for example configuration; Note: include files from
747 madwifi project is needed for building and a configuration file,
748 .config, needs to be created in hostapd directory with
749 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
751 * fixed an alignment issue that could cause SHA-1 to fail on some
752 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
754 * fixed RADIUS reconnection after an error in sending interim
756 * added hostapd control interface for external programs and an example
757 CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
758 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
759 'hostapd_cli sta <addr>')
760 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
761 * added support for strict GTK rekeying (wpa_strict_rekey in
763 * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
764 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
766 * added Prism54 driver interface (driver=prism54 in hostapd.conf;
767 note: .config needs to be created in hostapd directory with
768 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
770 * dual-licensed hostapd (GPLv2 and BSD licenses)
771 * fixed RADIUS accounting to generate a new session id for cases where
772 a station reassociates without first being complete deauthenticated
773 * fixed STA disassociation handler to mark next timeout state to
774 deauthenticate the station, i.e., skip long wait for inactivity poll
775 and extra disassociation, if the STA disassociates without
777 * added integrated EAP authenticator that can be used instead of
778 external RADIUS authentication server; currently, only EAP-MD5 is
779 supported, so this cannot yet be used for key distribution; the EAP
780 method interface is generic, though, so adding new EAP methods should
781 be straightforward; new hostapd.conf variables: 'eap_authenticator'
782 and 'eap_user_file'; this obsoletes "minimal authentication server"
783 ('minimal_eap' in hostapd.conf) which is now removed
784 * added support for FreeBSD and driver interface for the BSD net80211
785 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
786 .config); please note that some of the required kernel mods have not
789 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
790 * fixed some accounting cases where Accounting-Start was sent when
791 IEEE 802.1X port was being deauthorized
794 * modified RADIUS client to re-connect the socket in case of certain
795 error codes that are generated when a network interface state is
796 changes (e.g., when IP address changes or the interface is set UP)
797 * fixed couple of cases where EAPOL state for a station was freed
798 twice causing a segfault for hostapd
799 * fixed couple of bugs in processing WPA deauthentication (freed data
803 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
804 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
805 cases where STAs dropped multicast frames as replay attacks
806 * added support for copying RADIUS Attribute 'Class' from
807 authentication messages into accounting messages
808 * send canned EAP failure if RADIUS server sends Access-Reject without
809 EAP message (previously, Supplicant was not notified in this case)
810 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
811 not start EAPOL state machines if the STA selected to use WPA-PSK)
814 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
815 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
816 (i.e., IEEE 802.11i/D3.0)
817 - supports WPA-only, RSN-only, and mixed WPA/RSN mode
818 - both WPA-PSK and WPA-RADIUS/EAP are supported
819 - PMKSA caching and pre-authentication
820 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
821 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
822 rsn_preauth, rsn_preauth_interfaces
823 * fixed interim accounting to remove any pending accounting messages
824 to the STA before sending a new one
827 * added support for Acct-Interim-Interval:
828 - draft-ietf-radius-acct-interim-01.txt
829 - use Acct-Interim-Interval attribute from Access-Accept if local
830 'radius_acct_interim_interval' is not set
831 - allow different update intervals for each STA
832 * fixed event loop to call signal handlers only after returning from
833 the real signal handler
834 * reset sta->timeout_next after successful association to make sure
835 that the previously registered inactivity timer will not remove the
836 STA immediately (e.g., if STA deauthenticates and re-associates
837 before the timer is triggered).
838 * added new hostapd.conf variable, nas_identifier, that can be used to
839 add an optional RADIUS Attribute, NAS-Identifier, into authentication
840 and accounting messages
841 * added support for Accounting-On and Accounting-Off messages
842 * fixed accounting session handling to send Accounting-Start only once
843 per session and not to send Accounting-Stop if the session was not
845 * fixed Accounting-Stop statistics in cases where the message was
846 previously sent after the kernel entry for the STA (and/or IEEE
847 802.1X data) was removed
852 Older changes up to and including v0.1.0 are included in the ChangeLog
853 of the Host AP driver.
