529 is not fully backwards compatible, so out-of-tree driver wrappers
530 will need modifications
531 * cleaned up various module interfaces
532 * merge hostapd and wpa_supplicant developers' documentation into a
534 * fixed HT Capabilities IE with nl80211 drivers

540 * EAP-FAST server: piggyback Phase 2 start with the end of Phase 1
541 * WPS: add support for dynamically selecting whether to provision the
542 PSK as an ASCII passphrase or PSK
543 * added support for WDS (4-address frame) mode with per-station virtual
544 interfaces (wds_sta=1 in config file; only supported with
545 driver=nl80211 for now)
546 * fixed WPS Probe Request processing to handle missing required
548 * fixed PKCS#12 use with OpenSSL 1.0.0
549 * detect bridge interface automatically so that bridge parameter in
550 hostapd.conf becomes optional (though, it may now be used to
551 automatically add then WLAN interface into a bridge with
555 * increased hostapd_cli ping interval to 5 seconds and made this
556 configurable with a new command line options (-G<seconds>)
557 * driver_nl80211: use Linux socket filter to improve performance
558 * added support for external Registrars with WPS (UPnP transport)
559 * 802.11n: scan for overlapping BSSes before starting 20/40 MHz channel

561 reported correctly; TX/RX packets not yet available from kernel)
562 * added support for WPS USBA out-of-band mechanism with USB Flash
563 Drives (UFD) (CONFIG_WPS_UFD=y)
564 * fixed EAPOL/EAP reauthentication when using an external RADIUS
565 authentication server
566 * fixed TNC with EAP-TTLS
567 * fixed IEEE 802.11r key derivation function to match with the standard
568 (note: this breaks interoperability with previous version) [Bug 303]
569 * fixed SHA-256 based key derivation function to match with the
570 standard when using CCMP (for IEEE 802.11r and IEEE 802.11w)
571 (note: this breaks interoperability with previous version) [Bug 307]
572 * added number of code size optimizations to remove unnecessary
573 functionality from the program binary based on build configuration
574 (part of this automatic; part configurable with CONFIG_NO_* build

580 * fixed number of small WPS issues and added workarounds to
581 interoperate with common deployed broken implementations
582 * added some IEEE 802.11n co-existence rules to disable 40 MHz channels
583 or modify primary/secondary channels if needed based on neighboring
585 * added support for NFC out-of-band mechanism with WPS
586 * added preliminary support for IEEE 802.11r RIC processing
589 * added support for Wi-Fi Protected Setup (WPS)
590 (hostapd can now be configured to act as an integrated WPS Registrar
591 and provision credentials for WPS Enrollees using PIN and PBC
592 methods; external wireless Registrar can configure the AP, but
593 external WLAN Manager Registrars are not supported); WPS support can
594 be enabled by adding CONFIG_WPS=y into .config and setting the
595 runtime configuration variables in hostapd.conf (see WPS section in
596 the example configuration file); new hostapd_cli commands wps_pin and
597 wps_pbc are used to configure WPS negotiation; see README-WPS for
599 * added IEEE 802.11n HT capability configuration (ht_capab)
600 * added support for generating Country IE based on nl80211 regulatory
601 information (added if ieee80211d=1 in configuration)
602 * fixed WEP authentication (both Open System and Shared Key) with
604 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
605 * added support for using driver_test over UDP socket

607 * updated management frame protection to use IEEE 802.11w/D7.0
608 * fixed retransmission of EAP requests if no response is received
611 * added a new configuration option, wpa_ptk_rekey, that can be used to
612 enforce frequent PTK rekeying, e.g., to mitigate some attacks against
614 * updated OpenSSL code for EAP-FAST to use an updated version of the
615 session ticket overriding API that was included into the upstream
616 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
617 needed with that version anymore)
618 * changed channel flags configuration to read the information from
619 the driver (e.g., via driver_nl80211 when using mac80211) instead of
620 using hostapd as the source of the regulatory information (i.e.,
621 information from CRDA is now used with mac80211); this allows 5 GHz
622 channels to be used with hostapd (if allowed in the current
624 * fixed EAP-TLS message processing for the last TLS message if it is
625 large enough to require fragmentation (e.g., if a large Session
626 Ticket data is included)
627 * fixed listen interval configuration for nl80211 drivers
630 * added support for SHA-256 as X.509 certificate digest when using the
631 internal X.509/TLSv1 implementation
632 * fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer
634 * fixed internal TLSv1 implementation for abbreviated handshake (used
636 * added support for setting VLAN ID for STAs based on local MAC ACL
637 (accept_mac_file) as an alternative for RADIUS server-based
639 * updated management frame protection to use IEEE 802.11w/D6.0
640 (adds a new association ping to protect against unauthenticated
641 authenticate or (re)associate request frames dropping association)
642 * added support for using SHA256-based stronger key derivation for WPA2
644 * added new "driver wrapper" for RADIUS-only configuration
645 (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config)
646 * fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2)
647 is enabled in configuration
648 * changed EAP-FAST configuration to use separate fields for A-ID and
649 A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed
650 16-octet len binary value for better interoperability with some peer
651 implementations; eap_fast_a_id is now configured as a hex string
652 * driver_nl80211: Updated to match the current Linux mac80211 AP mode
653 configuration (wireless-testing.git and Linux kernel releases
654 starting from 2.6.29)
657 * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2
658 Identity Request if identity is already known
659 * added support for EAP Sequences in EAP-FAST Phase 2
660 * added support for EAP-TNC (Trusted Network Connect)
661 (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST
662 changes needed to run two methods in sequence (IF-T) and the IF-IMV
663 and IF-TNCCS interfaces from TNCS)
664 * added support for optional cryptobinding with PEAPv0
665 * added fragmentation support for EAP-TNC
666 * added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled)

672 MLME (driver_{hostap,nl80211,test}.c)
673 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
674 * copy optional Proxy-State attributes into RADIUS response when acting
675 as a RADIUS authentication server
676 * fixed EAPOL state machine to handle a case in which no response is
677 received from the RADIUS authentication server; previous version
678 could have triggered a crash in some cases after a timeout
679 * fixed EAP-SIM/AKA realm processing to allow decorated usernames to
681 * added a workaround for EAP-SIM/AKA peers that include incorrect null
682 termination in the username
683 * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER
684 attribute in notification messages only when using fast
686 * fixed EAP-SIM Start response processing for fast reauthentication
688 * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST}
689 phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method
692 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
693 lengths properly to avoid potential crash caused by invalid messages
694 * added data structure for storing allocated buffers (struct wpabuf);
695 this does not affect hostapd usage, but many of the APIs changed
696 and various interfaces (e.g., EAP) is not compatible with old
698 * added support for protecting EAP-AKA/Identity messages with
699 AT_CHECKCODE (optional feature in RFC 4187)
700 * added support for protected result indication with AT_RESULT_IND for
701 EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1)
702 * added support for configuring EAP-TTLS phase 2 non-EAP methods in
703 EAP server configuration; previously all four were enabled for every
704 phase 2 user, now all four are disabled by default and need to be
705 enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP,
707 * removed old debug printing mechanism and the related 'debug'
708 parameter in the configuration file; debug verbosity is now set with
709 -d (or -dd) command line arguments
710 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
711 only shared key/password authentication is supported in this version
714 * added experimental, integrated TLSv1 server implementation with the
715 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
716 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
717 .config); this can be useful, e.g., if the target system does not
718 have a suitable TLS library and a minimal code size is required
719 * added support for EAP-FAST server method to the integrated EAP
721 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
722 draft (draft-ietf-emu-eap-gpsk-07.txt)
723 * added a new configuration parameter, rsn_pairwise, to allow different
724 pairwise cipher suites to be enabled for WPA and RSN/WPA2
725 (note: if wpa_pairwise differs from rsn_pairwise, the driver will
726 either need to support this or will have to use the WPA/RSN IEs from
727 hostapd; currently, the included madwifi and bsd driver interfaces do
728 not have support for this)
729 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
732 * added experimental IEEE 802.11r/D6.0 support
733 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
734 * updated EAP-PSK to use the IANA-allocated EAP type 47
735 * fixed EAP-PSK bit ordering of the Flags field
736 * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
737 by reading wpa_psk_file [Bug 181]
738 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
739 * fixed IPv6 connection to RADIUS accounting server
740 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
741 draft (draft-ietf-emu-eap-gpsk-04.txt)
742 * hlr_auc_gw: read GSM triplet file into memory and rotate through the
743 entries instead of only using the same three triplets every time
744 (this does not work properly with tests using multiple clients, but
745 provides bit better triplet data for testing a single client; anyway,
746 if a better quality triplets are needed, GSM-Milenage should be used
747 instead of hardcoded triplet file)
748 * fixed EAP-MSCHAPv2 server to use a space between S and M parameters
749 in Success Request [Bug 203]
750 * added support for sending EAP-AKA Notifications in error cases
751 * updated to use IEEE 802.11w/D2.0 for management frame protection
753 * RADIUS server: added support for processing duplicate messages
754 (retransmissions from RADIUS client) by replying with the previous
758 * added support for configuring and controlling multiple BSSes per
759 radio interface (bss=<ifname> in hostapd.conf); this is only
760 available with Devicescape and test driver interfaces
761 * fixed PMKSA cache update in the end of successful RSN
763 * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
764 for each STA based on RADIUS Access-Accept attributes); this requires
765 VLAN support from the kernel driver/802.11 stack and this is
766 currently only available with Devicescape and test driver interfaces
767 * driver_madwifi: fixed configuration of unencrypted modes (plaintext
768 and IEEE 802.1X without WEP)
769 * removed STAKey handshake since PeerKey handshake has replaced it in
770 IEEE 802.11ma and there are no known deployments of STAKey
771 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
772 draft (draft-ietf-emu-eap-gpsk-01.txt)
773 * added preliminary implementation of IEEE 802.11w/D1.0 (management
775 (Note: this requires driver support to work properly.)
776 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
777 * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
778 * hlr_auc_gw: added support for reading per-IMSI Milenage keys and
779 parameters from a text file to make it possible to implement proper
780 GSM/UMTS authentication server for multiple SIM/USIM cards using
782 * fixed session timeout processing with drivers that do not use
783 ieee802_11.c (e.g., madwifi)
786 * added 'hostapd_cli new_sta <addr>' command for adding a new STA into
787 hostapd (e.g., to initialize wired network authentication based on an
789 * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
790 using WPA2 even if PMKSA caching is not used
791 * added -P<pid file> argument for hostapd to write the current process
793 * added support for RADIUS Authentication Server MIB (RFC 2619)
796 * fixed nt_password_hash build [Bug 144]
797 * added PeerKey handshake implementation for IEEE 802.11e
798 direct link setup (DLS) to replace STAKey handshake
799 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
800 draft-clancy-emu-eap-shared-secret-00.txt)
801 * fixed a segmentation fault when RSN pre-authentication was completed
802 successfully [Bug 152]
805 * do not build nt_password_hash and hlr_auc_gw by default to avoid
806 requiring a TLS library for a successful build; these programs can be
807 build with 'make nt_password_hash' and 'make hlr_auc_gw'
808 * added a new configuration option, eapol_version, that can be used to
809 set EAPOL version to 1 (default is 2) to work around broken client
810 implementations that drop EAPOL frames which use version number 2
812 * added support for EAP-SAKE (no EAP method number allocated yet, so
813 this is using the same experimental type 255 as EAP-PSK)
814 * fixed EAP-MSCHAPv2 message length validation
817 * fixed stdarg use in hostapd_logger(): if both stdout and syslog
818 logging was enabled, hostapd could trigger a segmentation fault in
819 vsyslog on some CPU -- C library combinations
820 * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
821 program to make it easier to use for implementing real SS7 gateway;
822 eap_sim_db is not anymore used as a file name for GSM authentication
823 triplets; instead, it is path to UNIX domain socket that will be used
824 to communicate with the external gateway program (e.g., hlr_auc_gw)
825 * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
826 local information (GSM authentication triplets from a text file and
827 hardcoded AKA authentication data); this can be used to test EAP-SIM
829 * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
830 to make it possible to test EAP-AKA with real USIM cards (this is
831 disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
833 * driver_madwifi: added support for getting station RSN IE from
834 madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
835 broken with earlier change (r1357) in the driver
836 * changed EAP method registration to use a dynamic list of methods
837 instead of a static list generated at build time
838 * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
840 * added ap_max_inactivity configuration parameter
843 * driver_test: added better support for multiple APs and STAs by using
844 a directory with sockets that include MAC address for each device in
845 the name (test_socket=DIR:/tmp/test)
846 * added support for EAP expanded type (vendor specific EAP methods)
848 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
849 * added experimental STAKey handshake implementation for IEEE 802.11e
850 direct link setup (DLS); note: this is disabled by default in both
851 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
853 * added support for EAP methods to use callbacks to external programs
854 by buffering a pending request and processing it after the EAP method
856 * improved EAP-SIM database interface to allow external request to GSM
857 HLR/AuC without blocking hostapd process
858 * added support for using EAP-SIM pseudonyms and fast re-authentication
859 * added support for EAP-AKA in the integrated EAP authenticator
860 * added support for matching EAP identity prefixes (e.g., "1"*) in EAP
861 user database to allow EAP-SIM/AKA selection without extra roundtrip
862 for EAP-Nak negotiation
863 * added support for storing EAP user password as NtPasswordHash instead
864 of plaintext password when using MSCHAP or MSCHAPv2 for
865 authentication (hash:<16-octet hex value>); added nt_password_hash
866 tool for hashing password to generate NtPasswordHash
868 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
869 * driver_wired: fixed EAPOL sending to optionally use PAE group address
870 as the destination instead of supplicant MAC address; this is
871 disabled by default, but should be enabled with use_pae_group_addr=1
872 in configuration file if the wired interface is used by only one
873 device at the time (common switch configuration)
874 * driver_madwifi: configure driver to use TKIP countermeasures in order
875 to get correct behavior (IEEE 802.11 association failing; previously,
876 association succeeded, but hostpad forced disassociation immediately)
877 * driver_madwifi: added support for madwifi-ng
880 * added support for replacing user identity from EAP with RADIUS
881 User-Name attribute from Access-Accept message, if that is included,
882 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
883 tunneled identity into accounting messages when the RADIUS server
884 does not support better way of doing this with Class attribute)
885 * driver_madwifi: fixed EAPOL packet receive for configuration where
886 ath# is part of a bridge interface
887 * added a configuration file and log analyzer script for logwatch
888 * fixed EAPOL state machine step function to process all state
889 transitions before processing new events; this resolves a race
890 condition in which EAPOL-Start message could trigger hostapd to send
891 two EAP-Response/Identity frames to the authentication server
894 * added client CA list to the TLS certificate request in order to make
895 it easier for the client to select which certificate to use
896 * added experimental support for EAP-PSK
897 * added support for WE-19 (hostap, madwifi)
900 * fixed build without CONFIG_RSN_PREAUTH
901 * fixed FreeBSD build
904 * fixed PMKSA caching to copy User-Name and Class attributes so that
905 RADIUS accounting gets correct information
906 * start RADIUS accounting only after successful completion of WPA
907 4-Way Handshake if WPA-PSK is used
908 * fixed PMKSA caching for the case where STA (re)associates without
912 * EAP-PAX is now registered as EAP type 46
913 * fixed EAP-PAX MAC calculation
914 * fixed EAP-PAX CK and ICK key derivation
915 * renamed eap_authenticator configuration variable to eap_server to
916 better match with RFC 3748 (EAP) terminology
917 * driver_test: added support for testing hostapd with wpa_supplicant
918 by using test driver interface without any kernel drivers or network
922 * fixed RADIUS server initialization when only auth or acct server
923 is configured and the other one is left empty
924 * driver_madwifi: added support for RADIUS accounting
925 * driver_madwifi: added preliminary support for compiling against 'BSD'
926 branch of madwifi CVS tree
927 * driver_madwifi: fixed pairwise key removal to allow WPA reauth
928 without disassociation
929 * added support for reading additional certificates from PKCS#12 files
930 and adding them to the certificate chain
931 * fixed RADIUS Class attribute processing to only use Access-Accept
932 packets to update Class; previously, other RADIUS authentication
933 packets could have cleared Class attribute
934 * added support for more than one Class attribute in RADIUS packets
935 * added support for verifying certificate revocation list (CRL) when
936 using integrated EAP authenticator for EAP-TLS; new hostapd.conf
937 options 'check_crl'; CRL must be included in the ca_cert file for now
939 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
940 * added support for including network information into
941 EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
942 (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
943 * fixed a bug which caused some RSN pre-authentication cases to use
944 freed memory and potentially crash hostapd
945 * fixed private key loading for cases where passphrase is not set
946 * added support for sending TLS alerts and aborting authentication
947 when receiving a TLS alert
948 * fixed WPA2 to add PMKSA cache entry when using integrated EAP
950 * fixed PMKSA caching (EAP authentication was not skipped correctly
951 with the new state machine changes from IEEE 802.1X draft)
952 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
953 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
954 to be added to .config to include IPv6 support); for RADIUS server,
955 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
956 in RADIUS clients file can then use IPv6 format
957 * added experimental support for EAP-PAX
958 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with
959 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
961 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
964 * added support for configuring a forced PEAP version based on the
966 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
967 to terminate authentication
968 * fixed EAP identifier duplicate processing with the new IEEE 802.1X
970 * clear accounting data in the driver when starting a new accounting
972 * driver_madwifi: filter wireless events based on ifindex to allow more
973 than one network interface to be used
974 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
975 setting if the packet does not pass MIC verification (e.g., due to
976 incorrect PSK); previously, message 1/4 was not tried again if an
977 invalid message 2/4 was received
978 * fixed reconfiguration of RADIUS client retransmission timer when
979 adding a new message to the pending list; previously, timer was not
980 updated at this point and if there was a pending message with long
981 time for the next retry, the new message needed to wait that long for
985 * added support for configuring multiple allowed EAP types for Phase 2
986 authentication (EAP-PEAP, EAP-TTLS)
987 * fixed EAPOL-Start processing to trigger WPA reauthentication
988 (previously, only EAPOL authentication was done)
991 * added support for EAP-PEAP in the integrated EAP authenticator
992 * added support for EAP-GTC in the integrated EAP authenticator
993 * added support for configuring list of EAP methods for Phase 1 so that
994 the integrated EAP authenticator can, e.g., use the wildcard entry
995 for EAP-TLS and EAP-PEAP
996 * added support for EAP-TTLS in the integrated EAP authenticator
997 * added support for EAP-SIM in the integrated EAP authenticator
998 * added support for using hostapd as a RADIUS authentication server
999 with the integrated EAP authenticator taking care of EAP
1000 authentication (new hostapd.conf options: radius_server_clients and
1001 radius_server_auth_port); this is not included in default build; use
1002 CONFIG_RADIUS_SERVER=y in .config to include
1005 * removed 'daemonize' configuration file option since it has not really
1006 been used at all for more than year
1007 * driver_madwifi: fixed group key setup and added get_ssid method
1008 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator
1011 * added support for integrated EAP-TLS authentication (new hostapd.conf
1012 variables: ca_cert, server_cert, private_key, private_key_passwd);
1013 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
1014 external RADIUS server
1015 * added support for reading PKCS#12 (PFX) files (as a replacement for
1016 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
1018 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
1019 * added support for Acct-{Input,Output}-Gigawords
1020 * added support for Event-Timestamp (in RADIUS Accounting-Requests)
1021 * added support for RADIUS Authentication Client MIB (RFC2618)
1022 * added support for RADIUS Accounting Client MIB (RFC2620)
1023 * made EAP re-authentication period configurable (eap_reauth_period)
1024 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
1025 * fixed EAPOL state machine to stop if STA is removed during
1026 eapol_sm_step(); this fixes at least one segfault triggering bug with
1027 IEEE 802.11i pre-authentication
1028 * added support for multiple WPA pre-shared keys (e.g., one for each
1029 client MAC address or keys shared by a group of clients);
1030 new hostapd.conf field wpa_psk_file for setting path to a text file
1031 containing PSKs, see hostapd.wpa_psk for an example
1032 * added support for multiple driver interfaces to allow hostapd to be
1033 used with other drivers
1034 * added wired authenticator driver interface (driver=wired in
1035 hostapd.conf, see wired.conf for example configuration)
1036 * added madwifi driver interface (driver=madwifi in hostapd.conf, see
1037 madwifi.conf for example configuration; Note: include files from
1038 madwifi project is needed for building and a configuration file,
1039 .config, needs to be created in hostapd directory with
1040 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
1042 * fixed an alignment issue that could cause SHA-1 to fail on some
1043 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
1045 * fixed RADIUS reconnection after an error in sending interim
1047 * added hostapd control interface for external programs and an example
1048 CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
1049 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
1050 'hostapd_cli sta <addr>')
1051 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
1052 * added support for strict GTK rekeying (wpa_strict_rekey in
1054 * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
1055 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
1057 * added Prism54 driver interface (driver=prism54 in hostapd.conf;
1058 note: .config needs to be created in hostapd directory with
1059 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
1061 * dual-licensed hostapd (GPLv2 and BSD licenses)
1062 * fixed RADIUS accounting to generate a new session id for cases where
1063 a station reassociates without first being complete deauthenticated
1064 * fixed STA disassociation handler to mark next timeout state to
1065 deauthenticate the station, i.e., skip long wait for inactivity poll
1066 and extra disassociation, if the STA disassociates without
1068 * added integrated EAP authenticator that can be used instead of
1069 external RADIUS authentication server; currently, only EAP-MD5 is
1070 supported, so this cannot yet be used for key distribution; the EAP
1071 method interface is generic, though, so adding new EAP methods should
1072 be straightforward; new hostapd.conf variables: 'eap_authenticator'
1073 and 'eap_user_file'; this obsoletes "minimal authentication server"
1074 ('minimal_eap' in hostapd.conf) which is now removed
1075 * added support for FreeBSD and driver interface for the BSD net80211
1076 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
1077 .config); please note that some of the required kernel mods have not
1080 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
1081 * fixed some accounting cases where Accounting-Start was sent when
1082 IEEE 802.1X port was being deauthorized
1085 * modified RADIUS client to re-connect the socket in case of certain
1086 error codes that are generated when a network interface state is
1087 changes (e.g., when IP address changes or the interface is set UP)
1088 * fixed couple of cases where EAPOL state for a station was freed
1089 twice causing a segfault for hostapd
1090 * fixed couple of bugs in processing WPA deauthentication (freed data
1094 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
1095 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
1096 cases where STAs dropped multicast frames as replay attacks
1097 * added support for copying RADIUS Attribute 'Class' from
1098 authentication messages into accounting messages
1099 * send canned EAP failure if RADIUS server sends Access-Reject without
1100 EAP message (previously, Supplicant was not notified in this case)
1101 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
1102 not start EAPOL state machines if the STA selected to use WPA-PSK)
1105 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
1106 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
1107 (i.e., IEEE 802.11i/D3.0)
1108 - supports WPA-only, RSN-only, and mixed WPA/RSN mode
1109 - both WPA-PSK and WPA-RADIUS/EAP are supported
1110 - PMKSA caching and pre-authentication
1111 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
1112 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
1113 rsn_preauth, rsn_preauth_interfaces
1114 * fixed interim accounting to remove any pending accounting messages
1115 to the STA before sending a new one
1118 * added support for Acct-Interim-Interval:
1119 - draft-ietf-radius-acct-interim-01.txt
1120 - use Acct-Interim-Interval attribute from Access-Accept if local
1121 'radius_acct_interim_interval' is not set
1122 - allow different update intervals for each STA
1123 * fixed event loop to call signal handlers only after returning from
1124 the real signal handler
1125 * reset sta->timeout_next after successful association to make sure
1126 that the previously registered inactivity timer will not remove the
1127 STA immediately (e.g., if STA deauthenticates and re-associates
1128 before the timer is triggered).
1129 * added new hostapd.conf variable, nas_identifier, that can be used to
1130 add an optional RADIUS Attribute, NAS-Identifier, into authentication
1131 and accounting messages
1132 * added support for Accounting-On and Accounting-Off messages
1133 * fixed accounting session handling to send Accounting-Start only once
1134 per session and not to send Accounting-Stop if the session was not
1135 initialized properly
1136 * fixed Accounting-Stop statistics in cases where the message was
1137 previously sent after the kernel entry for the STA (and/or IEEE
1138 802.1X data) was removed
1143 Older changes up to and including v0.1.0 are included in the ChangeLog
1144 of the Host AP driver.
