133 - Add command get version, that returns hostapd version string.
134 * WNM: Add BSS Transition Management Request for ESS Disassoc Imminent.
135 Use hostapd_cli ess_disassoc (STA addr) (URL) to send the
136 notification to the STA.
137 * Allow AP mode to disconnect STAs based on low ACK condition (when
138 the data connection is not working properly, e.g., due to the STA
139 going outside the range of the AP). Disabled by default, enable by
140 config option disassoc_low_ack.
141 * Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad

156 on failures up to 10.
157 - Allow AP to start in Enrollee mode without AP PIN for probing,
158 to be compatible with Windows 7.
159 - Add Config Error into WPS-FAIL events to provide more info
160 to the user on how to resolve the issue.
161 - When controlling multiple interfaces:
162 - apply WPS commands to all interfaces configured to use WPS
163 - apply WPS config changes to all interfaces that use WPS
164 - when an attack is detected on any interface, disable AP PIN on
167 - Show SetSelectedRegistrar events as ctrl_iface events.
168 - Add special AP Setup Locked mode to allow read only ER.
169 ap_setup_locked=2 can now be used to enable a special mode where

265 Drives (UFD) (CONFIG_WPS_UFD=y)
266 * fixed EAPOL/EAP reauthentication when using an external RADIUS
267 authentication server
268 * fixed TNC with EAP-TTLS

270 (note: this breaks interoperability with previous version) [Bug 303]
271 * fixed SHA-256 based key derivation function to match with the
272 standard when using CCMP (for IEEE 802.11r and IEEE 802.11w)
273 (note: this breaks interoperability with previous version) [Bug 307]
274 * added number of code size optimizations to remove unnecessary
275 functionality from the program binary based on build configuration

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

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

343 authenticate or (re)associate request frames dropping association)
344 * added support for using SHA256-based stronger key derivation for WPA2
346 * added new "driver wrapper" for RADIUS-only configuration
347 (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config)
348 * fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2)
349 is enabled in configuration
350 * changed EAP-FAST configuration to use separate fields for A-ID and
351 A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed
352 16-octet len binary value for better interoperability with some peer
353 implementations; eap_fast_a_id is now configured as a hex string
354 * driver_nl80211: Updated to match the current Linux mac80211 AP mode
355 configuration (wireless-testing.git and Linux kernel releases
356 starting from 2.6.29)
359 * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2
360 Identity Request if identity is already known
361 * added support for EAP Sequences in EAP-FAST Phase 2

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

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

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

442 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
443 draft (draft-ietf-emu-eap-gpsk-04.txt)
444 * hlr_auc_gw: read GSM triplet file into memory and rotate through the
445 entries instead of only using the same three triplets every time
446 (this does not work properly with tests using multiple clients, but
447 provides bit better triplet data for testing a single client; anyway,
448 if a better quality triplets are needed, GSM-Milenage should be used
449 instead of hardcoded triplet file)
450 * fixed EAP-MSCHAPv2 server to use a space between S and M parameters
451 in Success Request [Bug 203]
452 * added support for sending EAP-AKA Notifications in error cases
453 * updated to use IEEE 802.11w/D2.0 for management frame protection

456 (retransmissions from RADIUS client) by replying with the previous
460 * added support for configuring and controlling multiple BSSes per
461 radio interface (bss=<ifname> in hostapd.conf); this is only
462 available with Devicescape and test driver interfaces
463 * fixed PMKSA cache update in the end of successful RSN
465 * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
466 for each STA based on RADIUS Access-Accept attributes); this requires
467 VLAN support from the kernel driver/802.11 stack and this is
468 currently only available with Devicescape and test driver interfaces
469 * driver_madwifi: fixed configuration of unencrypted modes (plaintext
470 and IEEE 802.1X without WEP)
471 * removed STAKey handshake since PeerKey handshake has replaced it in
472 IEEE 802.11ma and there are no known deployments of STAKey
473 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
474 draft (draft-ietf-emu-eap-gpsk-01.txt)
475 * added preliminary implementation of IEEE 802.11w/D1.0 (management
477 (Note: this requires driver support to work properly.)
478 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
479 * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
480 * hlr_auc_gw: added support for reading per-IMSI Milenage keys and
481 parameters from a text file to make it possible to implement proper
482 GSM/UMTS authentication server for multiple SIM/USIM cards using
484 * fixed session timeout processing with drivers that do not use
485 ieee802_11.c (e.g., madwifi)
488 * added 'hostapd_cli new_sta <addr>' command for adding a new STA into
489 hostapd (e.g., to initialize wired network authentication based on an
491 * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
492 using WPA2 even if PMKSA caching is not used
493 * added -P<pid file> argument for hostapd to write the current process
495 * added support for RADIUS Authentication Server MIB (RFC 2619)
498 * fixed nt_password_hash build [Bug 144]
499 * added PeerKey handshake implementation for IEEE 802.11e
500 direct link setup (DLS) to replace STAKey handshake
501 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
502 draft-clancy-emu-eap-shared-secret-00.txt)
503 * fixed a segmentation fault when RSN pre-authentication was completed
504 successfully [Bug 152]
507 * do not build nt_password_hash and hlr_auc_gw by default to avoid
508 requiring a TLS library for a successful build; these programs can be
509 build with 'make nt_password_hash' and 'make hlr_auc_gw'
510 * added a new configuration option, eapol_version, that can be used to
511 set EAPOL version to 1 (default is 2) to work around broken client
512 implementations that drop EAPOL frames which use version number 2
514 * added support for EAP-SAKE (no EAP method number allocated yet, so
515 this is using the same experimental type 255 as EAP-PSK)
516 * fixed EAP-MSCHAPv2 message length validation
519 * fixed stdarg use in hostapd_logger(): if both stdout and syslog
520 logging was enabled, hostapd could trigger a segmentation fault in
521 vsyslog on some CPU -- C library combinations
522 * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
523 program to make it easier to use for implementing real SS7 gateway;
524 eap_sim_db is not anymore used as a file name for GSM authentication
525 triplets; instead, it is path to UNIX domain socket that will be used
526 to communicate with the external gateway program (e.g., hlr_auc_gw)
527 * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
528 local information (GSM authentication triplets from a text file and
529 hardcoded AKA authentication data); this can be used to test EAP-SIM
531 * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
532 to make it possible to test EAP-AKA with real USIM cards (this is
533 disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
535 * driver_madwifi: added support for getting station RSN IE from
536 madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
537 broken with earlier change (r1357) in the driver
538 * changed EAP method registration to use a dynamic list of methods
539 instead of a static list generated at build time
540 * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
542 * added ap_max_inactivity configuration parameter
545 * driver_test: added better support for multiple APs and STAs by using
546 a directory with sockets that include MAC address for each device in
547 the name (test_socket=DIR:/tmp/test)
548 * added support for EAP expanded type (vendor specific EAP methods)
550 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
551 * added experimental STAKey handshake implementation for IEEE 802.11e
552 direct link setup (DLS); note: this is disabled by default in both
553 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
555 * added support for EAP methods to use callbacks to external programs
556 by buffering a pending request and processing it after the EAP method
558 * improved EAP-SIM database interface to allow external request to GSM
559 HLR/AuC without blocking hostapd process
560 * added support for using EAP-SIM pseudonyms and fast re-authentication
561 * added support for EAP-AKA in the integrated EAP authenticator
562 * added support for matching EAP identity prefixes (e.g., "1"*) in EAP
563 user database to allow EAP-SIM/AKA selection without extra roundtrip
564 for EAP-Nak negotiation
565 * added support for storing EAP user password as NtPasswordHash instead
566 of plaintext password when using MSCHAP or MSCHAPv2 for
567 authentication (hash:<16-octet hex value>); added nt_password_hash
568 tool for hashing password to generate NtPasswordHash
570 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
571 * driver_wired: fixed EAPOL sending to optionally use PAE group address
572 as the destination instead of supplicant MAC address; this is
573 disabled by default, but should be enabled with use_pae_group_addr=1
574 in configuration file if the wired interface is used by only one
575 device at the time (common switch configuration)
576 * driver_madwifi: configure driver to use TKIP countermeasures in order
577 to get correct behavior (IEEE 802.11 association failing; previously,
578 association succeeded, but hostpad forced disassociation immediately)
579 * driver_madwifi: added support for madwifi-ng
582 * added support for replacing user identity from EAP with RADIUS
583 User-Name attribute from Access-Accept message, if that is included,
584 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
585 tunneled identity into accounting messages when the RADIUS server
586 does not support better way of doing this with Class attribute)
587 * driver_madwifi: fixed EAPOL packet receive for configuration where
588 ath# is part of a bridge interface
589 * added a configuration file and log analyzer script for logwatch
590 * fixed EAPOL state machine step function to process all state
591 transitions before processing new events; this resolves a race
592 condition in which EAPOL-Start message could trigger hostapd to send
593 two EAP-Response/Identity frames to the authentication server
596 * added client CA list to the TLS certificate request in order to make
597 it easier for the client to select which certificate to use
598 * added experimental support for EAP-PSK
599 * added support for WE-19 (hostap, madwifi)
602 * fixed build without CONFIG_RSN_PREAUTH
603 * fixed FreeBSD build
606 * fixed PMKSA caching to copy User-Name and Class attributes so that
607 RADIUS accounting gets correct information
608 * start RADIUS accounting only after successful completion of WPA
609 4-Way Handshake if WPA-PSK is used
610 * fixed PMKSA caching for the case where STA (re)associates without
614 * EAP-PAX is now registered as EAP type 46
615 * fixed EAP-PAX MAC calculation
616 * fixed EAP-PAX CK and ICK key derivation
617 * renamed eap_authenticator configuration variable to eap_server to
618 better match with RFC 3748 (EAP) terminology
619 * driver_test: added support for testing hostapd with wpa_supplicant
620 by using test driver interface without any kernel drivers or network
624 * fixed RADIUS server initialization when only auth or acct server
625 is configured and the other one is left empty
626 * driver_madwifi: added support for RADIUS accounting
627 * driver_madwifi: added preliminary support for compiling against 'BSD'
628 branch of madwifi CVS tree
629 * driver_madwifi: fixed pairwise key removal to allow WPA reauth
630 without disassociation
631 * added support for reading additional certificates from PKCS#12 files
632 and adding them to the certificate chain
633 * fixed RADIUS Class attribute processing to only use Access-Accept
634 packets to update Class; previously, other RADIUS authentication
635 packets could have cleared Class attribute
636 * added support for more than one Class attribute in RADIUS packets
637 * added support for verifying certificate revocation list (CRL) when
638 using integrated EAP authenticator for EAP-TLS; new hostapd.conf
639 options 'check_crl'; CRL must be included in the ca_cert file for now
641 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
642 * added support for including network information into
643 EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
644 (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
645 * fixed a bug which caused some RSN pre-authentication cases to use
646 freed memory and potentially crash hostapd
647 * fixed private key loading for cases where passphrase is not set
648 * added support for sending TLS alerts and aborting authentication
649 when receiving a TLS alert
650 * fixed WPA2 to add PMKSA cache entry when using integrated EAP
652 * fixed PMKSA caching (EAP authentication was not skipped correctly
653 with the new state machine changes from IEEE 802.1X draft)
654 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
655 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
656 to be added to .config to include IPv6 support); for RADIUS server,
657 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
658 in RADIUS clients file can then use IPv6 format
659 * added experimental support for EAP-PAX
660 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with
661 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
663 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
666 * added support for configuring a forced PEAP version based on the
668 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
669 to terminate authentication
670 * fixed EAP identifier duplicate processing with the new IEEE 802.1X
672 * clear accounting data in the driver when starting a new accounting
674 * driver_madwifi: filter wireless events based on ifindex to allow more
675 than one network interface to be used
676 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
677 setting if the packet does not pass MIC verification (e.g., due to
678 incorrect PSK); previously, message 1/4 was not tried again if an
679 invalid message 2/4 was received
680 * fixed reconfiguration of RADIUS client retransmission timer when
681 adding a new message to the pending list; previously, timer was not
682 updated at this point and if there was a pending message with long
683 time for the next retry, the new message needed to wait that long for
687 * added support for configuring multiple allowed EAP types for Phase 2
688 authentication (EAP-PEAP, EAP-TTLS)
689 * fixed EAPOL-Start processing to trigger WPA reauthentication
690 (previously, only EAPOL authentication was done)
693 * added support for EAP-PEAP in the integrated EAP authenticator
694 * added support for EAP-GTC in the integrated EAP authenticator
695 * added support for configuring list of EAP methods for Phase 1 so that
696 the integrated EAP authenticator can, e.g., use the wildcard entry
697 for EAP-TLS and EAP-PEAP
698 * added support for EAP-TTLS in the integrated EAP authenticator
699 * added support for EAP-SIM in the integrated EAP authenticator
700 * added support for using hostapd as a RADIUS authentication server
701 with the integrated EAP authenticator taking care of EAP
702 authentication (new hostapd.conf options: radius_server_clients and
703 radius_server_auth_port); this is not included in default build; use
704 CONFIG_RADIUS_SERVER=y in .config to include
707 * removed 'daemonize' configuration file option since it has not really
708 been used at all for more than year
709 * driver_madwifi: fixed group key setup and added get_ssid method
710 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator
713 * added support for integrated EAP-TLS authentication (new hostapd.conf
714 variables: ca_cert, server_cert, private_key, private_key_passwd);
715 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
716 external RADIUS server
717 * added support for reading PKCS#12 (PFX) files (as a replacement for
718 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
720 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
721 * added support for Acct-{Input,Output}-Gigawords
722 * added support for Event-Timestamp (in RADIUS Accounting-Requests)
723 * added support for RADIUS Authentication Client MIB (RFC2618)
724 * added support for RADIUS Accounting Client MIB (RFC2620)
725 * made EAP re-authentication period configurable (eap_reauth_period)
726 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
727 * fixed EAPOL state machine to stop if STA is removed during
728 eapol_sm_step(); this fixes at least one segfault triggering bug with
729 IEEE 802.11i pre-authentication
730 * added support for multiple WPA pre-shared keys (e.g., one for each
731 client MAC address or keys shared by a group of clients);
732 new hostapd.conf field wpa_psk_file for setting path to a text file
733 containing PSKs, see hostapd.wpa_psk for an example
734 * added support for multiple driver interfaces to allow hostapd to be
735 used with other drivers
736 * added wired authenticator driver interface (driver=wired in
737 hostapd.conf, see wired.conf for example configuration)
738 * added madwifi driver interface (driver=madwifi in hostapd.conf, see
739 madwifi.conf for example configuration; Note: include files from
740 madwifi project is needed for building and a configuration file,
741 .config, needs to be created in hostapd directory with
742 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
744 * fixed an alignment issue that could cause SHA-1 to fail on some
745 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
747 * fixed RADIUS reconnection after an error in sending interim
749 * added hostapd control interface for external programs and an example
750 CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
751 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
752 'hostapd_cli sta <addr>')
753 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
754 * added support for strict GTK rekeying (wpa_strict_rekey in
756 * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
757 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
759 * added Prism54 driver interface (driver=prism54 in hostapd.conf;
760 note: .config needs to be created in hostapd directory with
761 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
763 * dual-licensed hostapd (GPLv2 and BSD licenses)
764 * fixed RADIUS accounting to generate a new session id for cases where
765 a station reassociates without first being complete deauthenticated
766 * fixed STA disassociation handler to mark next timeout state to
767 deauthenticate the station, i.e., skip long wait for inactivity poll
768 and extra disassociation, if the STA disassociates without
770 * added integrated EAP authenticator that can be used instead of
771 external RADIUS authentication server; currently, only EAP-MD5 is
772 supported, so this cannot yet be used for key distribution; the EAP
773 method interface is generic, though, so adding new EAP methods should
774 be straightforward; new hostapd.conf variables: 'eap_authenticator'
775 and 'eap_user_file'; this obsoletes "minimal authentication server"
776 ('minimal_eap' in hostapd.conf) which is now removed
777 * added support for FreeBSD and driver interface for the BSD net80211
778 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
779 .config); please note that some of the required kernel mods have not
782 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
783 * fixed some accounting cases where Accounting-Start was sent when
784 IEEE 802.1X port was being deauthorized
787 * modified RADIUS client to re-connect the socket in case of certain
788 error codes that are generated when a network interface state is
789 changes (e.g., when IP address changes or the interface is set UP)
790 * fixed couple of cases where EAPOL state for a station was freed
791 twice causing a segfault for hostapd
792 * fixed couple of bugs in processing WPA deauthentication (freed data
796 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
797 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
798 cases where STAs dropped multicast frames as replay attacks
799 * added support for copying RADIUS Attribute 'Class' from
800 authentication messages into accounting messages
801 * send canned EAP failure if RADIUS server sends Access-Reject without
802 EAP message (previously, Supplicant was not notified in this case)
803 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
804 not start EAPOL state machines if the STA selected to use WPA-PSK)
807 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
808 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
809 (i.e., IEEE 802.11i/D3.0)
810 - supports WPA-only, RSN-only, and mixed WPA/RSN mode
811 - both WPA-PSK and WPA-RADIUS/EAP are supported
812 - PMKSA caching and pre-authentication
813 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
814 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
815 rsn_preauth, rsn_preauth_interfaces
816 * fixed interim accounting to remove any pending accounting messages
817 to the STA before sending a new one
820 * added support for Acct-Interim-Interval:
821 - draft-ietf-radius-acct-interim-01.txt
822 - use Acct-Interim-Interval attribute from Access-Accept if local
823 'radius_acct_interim_interval' is not set
824 - allow different update intervals for each STA
825 * fixed event loop to call signal handlers only after returning from
826 the real signal handler
827 * reset sta->timeout_next after successful association to make sure
828 that the previously registered inactivity timer will not remove the
829 STA immediately (e.g., if STA deauthenticates and re-associates
830 before the timer is triggered).
831 * added new hostapd.conf variable, nas_identifier, that can be used to
832 add an optional RADIUS Attribute, NAS-Identifier, into authentication
833 and accounting messages
834 * added support for Accounting-On and Accounting-Off messages
835 * fixed accounting session handling to send Accounting-Start only once
836 per session and not to send Accounting-Stop if the session was not
838 * fixed Accounting-Stop statistics in cases where the message was
839 previously sent after the kernel entry for the STA (and/or IEEE
840 802.1X data) was removed
845 Older changes up to and including v0.1.0 are included in the ChangeLog
846 of the Host AP driver.
