532 This allows the driver to use PS buffering of Deauthentication and
533 Disassociation frames when the STA is in power save sleep. Only
534 available with drivers that provide TX status events for Deauth/
535 Disassoc frames (nl80211).
536 * Allow PMKSA caching to be disabled on the Authenticator. See
537 hostap.conf config parameter disable_pmksa_caching.
538 * atheros: Add support for IEEE 802.11w configuration.
539 * bsd: Add support for setting HT values in IFM_MMASK.

564 - Many WPS/WPS ER commands - see WPS/WPS ER sections for details.
565 - Add command get version, that returns hostapd version string.
566 * WNM: Add BSS Transition Management Request for ESS Disassoc Imminent.
567 Use hostapd_cli ess_disassoc (STA addr) (URL) to send the
568 notification to the STA.
569 * Allow AP mode to disconnect STAs based on low ACK condition (when
570 the data connection is not working properly, e.g., due to the STA
571 going outside the range of the AP). Disabled by default, enable by
572 config option disassoc_low_ack.
573 * Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad
576 - Send AP Settings as a wrapped Credential attribute to ctrl_iface
577 in WPS-NEW-AP-SETTINGS.

583 validate the checksum digit (if present).
584 - Add hostap_cli get_config command to display current AP config.
585 - Add new hostapd_cli command, wps_ap_pin, to manage AP PIN at
586 runtime and support dynamic AP PIN management.
587 - Disable AP PIN after 10 consecutive failures. Slow down attacks
588 on failures up to 10.
589 - Allow AP to start in Enrollee mode without AP PIN for probing,
590 to be compatible with Windows 7.
591 - Add Config Error into WPS-FAIL events to provide more info
592 to the user on how to resolve the issue.
593 - When controlling multiple interfaces:
594 - apply WPS commands to all interfaces configured to use WPS
595 - apply WPS config changes to all interfaces that use WPS
596 - when an attack is detected on any interface, disable AP PIN on
599 - Show SetSelectedRegistrar events as ctrl_iface events.
600 - Add special AP Setup Locked mode to allow read only ER.
601 ap_setup_locked=2 can now be used to enable a special mode where
602 WPS ER can learn the current AP settings, but cannot change them.
603 * WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2)
604 - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool

614 fragment_size in hostapd.conf).
615 * wlantest: Add a tool wlantest for IEEE802.11 protocol testing.
616 wlantest can be used to capture frames from a monitor interface
617 for realtime capturing or from pcap files for offline analysis.
618 * Interworking: Support added for 802.11u. Enable in .config with
619 CONFIG_INTERWORKING. See hostapd.conf for config parameters for
621 * Android: Add build and runtime support for Android hostapd.
622 * Add a new debug message level for excessive information. Use
624 * TLS: Add support for tls_disable_time_checks=1 in client mode.
626 - Add support for TLS v1.1 (RFC 4346). Enable with build parameter
628 - Add domainComponent parser for X.509 names
629 * Reorder some IEs to get closer to IEEE 802.11 standard. Move
630 WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames.
631 Move HT IEs to be later in (Re)Assoc Resp.

663 is not fully backwards compatible, so out-of-tree driver wrappers
664 will need modifications
665 * cleaned up various module interfaces
666 * merge hostapd and wpa_supplicant developers' documentation into a
668 * fixed HT Capabilities IE with nl80211 drivers

680 * fixed WPS Probe Request processing to handle missing required
682 * fixed PKCS#12 use with OpenSSL 1.0.0
683 * detect bridge interface automatically so that bridge parameter in
684 hostapd.conf becomes optional (though, it may now be used to
685 automatically add then WLAN interface into a bridge with
689 * increased hostapd_cli ping interval to 5 seconds and made this
690 configurable with a new command line options (-G<seconds>)
691 * driver_nl80211: use Linux socket filter to improve performance

696 * added support for WPS USBA out-of-band mechanism with USB Flash
697 Drives (UFD) (CONFIG_WPS_UFD=y)
698 * fixed EAPOL/EAP reauthentication when using an external RADIUS
699 authentication server
700 * fixed TNC with EAP-TTLS
701 * fixed IEEE 802.11r key derivation function to match with the standard
702 (note: this breaks interoperability with previous version) [Bug 303]
703 * fixed SHA-256 based key derivation function to match with the
704 standard when using CCMP (for IEEE 802.11r and IEEE 802.11w)
705 (note: this breaks interoperability with previous version) [Bug 307]
706 * added number of code size optimizations to remove unnecessary
707 functionality from the program binary based on build configuration
708 (part of this automatic; part configurable with CONFIG_NO_* build

714 * fixed number of small WPS issues and added workarounds to
715 interoperate with common deployed broken implementations
716 * added some IEEE 802.11n co-existence rules to disable 40 MHz channels
717 or modify primary/secondary channels if needed based on neighboring
719 * added support for NFC out-of-band mechanism with WPS
720 * added preliminary support for IEEE 802.11r RIC processing
723 * added support for Wi-Fi Protected Setup (WPS)
724 (hostapd can now be configured to act as an integrated WPS Registrar
725 and provision credentials for WPS Enrollees using PIN and PBC
726 methods; external wireless Registrar can configure the AP, but
727 external WLAN Manager Registrars are not supported); WPS support can
728 be enabled by adding CONFIG_WPS=y into .config and setting the
729 runtime configuration variables in hostapd.conf (see WPS section in
730 the example configuration file); new hostapd_cli commands wps_pin and
731 wps_pbc are used to configure WPS negotiation; see README-WPS for
733 * added IEEE 802.11n HT capability configuration (ht_capab)
734 * added support for generating Country IE based on nl80211 regulatory
735 information (added if ieee80211d=1 in configuration)

742 * fixed retransmission of EAP requests if no response is received
745 * added a new configuration option, wpa_ptk_rekey, that can be used to
746 enforce frequent PTK rekeying, e.g., to mitigate some attacks against
748 * updated OpenSSL code for EAP-FAST to use an updated version of the
749 session ticket overriding API that was included into the upstream
750 OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
751 needed with that version anymore)
752 * changed channel flags configuration to read the information from
753 the driver (e.g., via driver_nl80211 when using mac80211) instead of
754 using hostapd as the source of the regulatory information (i.e.,
755 information from CRDA is now used with mac80211); this allows 5 GHz
756 channels to be used with hostapd (if allowed in the current
758 * fixed EAP-TLS message processing for the last TLS message if it is
759 large enough to require fragmentation (e.g., if a large Session
760 Ticket data is included)
761 * fixed listen interval configuration for nl80211 drivers
764 * added support for SHA-256 as X.509 certificate digest when using the
765 internal X.509/TLSv1 implementation
766 * fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer
768 * fixed internal TLSv1 implementation for abbreviated handshake (used
770 * added support for setting VLAN ID for STAs based on local MAC ACL
771 (accept_mac_file) as an alternative for RADIUS server-based
773 * updated management frame protection to use IEEE 802.11w/D6.0
774 (adds a new association ping to protect against unauthenticated
775 authenticate or (re)associate request frames dropping association)
776 * added support for using SHA256-based stronger key derivation for WPA2
778 * added new "driver wrapper" for RADIUS-only configuration
779 (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config)
780 * fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2)
781 is enabled in configuration
782 * changed EAP-FAST configuration to use separate fields for A-ID and
783 A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed
784 16-octet len binary value for better interoperability with some peer
785 implementations; eap_fast_a_id is now configured as a hex string
786 * driver_nl80211: Updated to match the current Linux mac80211 AP mode
787 configuration (wireless-testing.git and Linux kernel releases
788 starting from 2.6.29)
791 * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2
792 Identity Request if identity is already known
793 * added support for EAP Sequences in EAP-FAST Phase 2
794 * added support for EAP-TNC (Trusted Network Connect)
795 (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST
796 changes needed to run two methods in sequence (IF-T) and the IF-IMV
797 and IF-TNCCS interfaces from TNCS)
798 * added support for optional cryptobinding with PEAPv0
799 * added fragmentation support for EAP-TNC
800 * added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled)
802 * added support for opportunistic key caching (OKC)
805 * fixed Reassociation Response callback processing when using internal
806 MLME (driver_{hostap,nl80211,test}.c)
807 * updated FT support to use the latest draft, IEEE 802.11r/D9.0
808 * copy optional Proxy-State attributes into RADIUS response when acting
809 as a RADIUS authentication server
810 * fixed EAPOL state machine to handle a case in which no response is
811 received from the RADIUS authentication server; previous version
812 could have triggered a crash in some cases after a timeout
813 * fixed EAP-SIM/AKA realm processing to allow decorated usernames to
815 * added a workaround for EAP-SIM/AKA peers that include incorrect null
816 termination in the username
817 * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER
818 attribute in notification messages only when using fast
820 * fixed EAP-SIM Start response processing for fast reauthentication
822 * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST}
823 phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method
826 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
827 lengths properly to avoid potential crash caused by invalid messages
828 * added data structure for storing allocated buffers (struct wpabuf);
829 this does not affect hostapd usage, but many of the APIs changed
830 and various interfaces (e.g., EAP) is not compatible with old
832 * added support for protecting EAP-AKA/Identity messages with
833 AT_CHECKCODE (optional feature in RFC 4187)
834 * added support for protected result indication with AT_RESULT_IND for
835 EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1)
836 * added support for configuring EAP-TTLS phase 2 non-EAP methods in
837 EAP server configuration; previously all four were enabled for every
838 phase 2 user, now all four are disabled by default and need to be
839 enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP,
841 * removed old debug printing mechanism and the related 'debug'
842 parameter in the configuration file; debug verbosity is now set with
843 -d (or -dd) command line arguments
844 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
845 only shared key/password authentication is supported in this version
848 * added experimental, integrated TLSv1 server implementation with the
849 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
850 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
851 .config); this can be useful, e.g., if the target system does not
852 have a suitable TLS library and a minimal code size is required
853 * added support for EAP-FAST server method to the integrated EAP
855 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
856 draft (draft-ietf-emu-eap-gpsk-07.txt)
857 * added a new configuration parameter, rsn_pairwise, to allow different
858 pairwise cipher suites to be enabled for WPA and RSN/WPA2
859 (note: if wpa_pairwise differs from rsn_pairwise, the driver will
860 either need to support this or will have to use the WPA/RSN IEs from
861 hostapd; currently, the included madwifi and bsd driver interfaces do
862 not have support for this)
863 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
866 * added experimental IEEE 802.11r/D6.0 support
867 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
868 * updated EAP-PSK to use the IANA-allocated EAP type 47
869 * fixed EAP-PSK bit ordering of the Flags field
870 * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
871 by reading wpa_psk_file [Bug 181]
872 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
873 * fixed IPv6 connection to RADIUS accounting server
874 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
875 draft (draft-ietf-emu-eap-gpsk-04.txt)
876 * hlr_auc_gw: read GSM triplet file into memory and rotate through the
877 entries instead of only using the same three triplets every time
878 (this does not work properly with tests using multiple clients, but
879 provides bit better triplet data for testing a single client; anyway,
880 if a better quality triplets are needed, GSM-Milenage should be used
881 instead of hardcoded triplet file)
882 * fixed EAP-MSCHAPv2 server to use a space between S and M parameters
883 in Success Request [Bug 203]
884 * added support for sending EAP-AKA Notifications in error cases
885 * updated to use IEEE 802.11w/D2.0 for management frame protection
887 * RADIUS server: added support for processing duplicate messages
888 (retransmissions from RADIUS client) by replying with the previous
892 * added support for configuring and controlling multiple BSSes per
893 radio interface (bss=<ifname> in hostapd.conf); this is only
894 available with Devicescape and test driver interfaces
895 * fixed PMKSA cache update in the end of successful RSN
897 * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
898 for each STA based on RADIUS Access-Accept attributes); this requires
899 VLAN support from the kernel driver/802.11 stack and this is
900 currently only available with Devicescape and test driver interfaces
901 * driver_madwifi: fixed configuration of unencrypted modes (plaintext
902 and IEEE 802.1X without WEP)
903 * removed STAKey handshake since PeerKey handshake has replaced it in
904 IEEE 802.11ma and there are no known deployments of STAKey
905 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
906 draft (draft-ietf-emu-eap-gpsk-01.txt)
907 * added preliminary implementation of IEEE 802.11w/D1.0 (management
909 (Note: this requires driver support to work properly.)
910 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
911 * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
912 * hlr_auc_gw: added support for reading per-IMSI Milenage keys and
913 parameters from a text file to make it possible to implement proper
914 GSM/UMTS authentication server for multiple SIM/USIM cards using
916 * fixed session timeout processing with drivers that do not use
917 ieee802_11.c (e.g., madwifi)
920 * added 'hostapd_cli new_sta <addr>' command for adding a new STA into
921 hostapd (e.g., to initialize wired network authentication based on an
923 * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
924 using WPA2 even if PMKSA caching is not used
925 * added -P<pid file> argument for hostapd to write the current process
927 * added support for RADIUS Authentication Server MIB (RFC 2619)
930 * fixed nt_password_hash build [Bug 144]
931 * added PeerKey handshake implementation for IEEE 802.11e
932 direct link setup (DLS) to replace STAKey handshake
933 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
934 draft-clancy-emu-eap-shared-secret-00.txt)
935 * fixed a segmentation fault when RSN pre-authentication was completed
936 successfully [Bug 152]
939 * do not build nt_password_hash and hlr_auc_gw by default to avoid
940 requiring a TLS library for a successful build; these programs can be
941 build with 'make nt_password_hash' and 'make hlr_auc_gw'
942 * added a new configuration option, eapol_version, that can be used to
943 set EAPOL version to 1 (default is 2) to work around broken client
944 implementations that drop EAPOL frames which use version number 2
946 * added support for EAP-SAKE (no EAP method number allocated yet, so
947 this is using the same experimental type 255 as EAP-PSK)
948 * fixed EAP-MSCHAPv2 message length validation
951 * fixed stdarg use in hostapd_logger(): if both stdout and syslog
952 logging was enabled, hostapd could trigger a segmentation fault in
953 vsyslog on some CPU -- C library combinations
954 * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
955 program to make it easier to use for implementing real SS7 gateway;
956 eap_sim_db is not anymore used as a file name for GSM authentication
957 triplets; instead, it is path to UNIX domain socket that will be used
958 to communicate with the external gateway program (e.g., hlr_auc_gw)
959 * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
960 local information (GSM authentication triplets from a text file and
961 hardcoded AKA authentication data); this can be used to test EAP-SIM
963 * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
964 to make it possible to test EAP-AKA with real USIM cards (this is
965 disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
967 * driver_madwifi: added support for getting station RSN IE from
968 madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
969 broken with earlier change (r1357) in the driver
970 * changed EAP method registration to use a dynamic list of methods
971 instead of a static list generated at build time
972 * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
974 * added ap_max_inactivity configuration parameter
977 * driver_test: added better support for multiple APs and STAs by using
978 a directory with sockets that include MAC address for each device in
979 the name (test_socket=DIR:/tmp/test)
980 * added support for EAP expanded type (vendor specific EAP methods)
982 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
983 * added experimental STAKey handshake implementation for IEEE 802.11e
984 direct link setup (DLS); note: this is disabled by default in both
985 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
987 * added support for EAP methods to use callbacks to external programs
988 by buffering a pending request and processing it after the EAP method
990 * improved EAP-SIM database interface to allow external request to GSM
991 HLR/AuC without blocking hostapd process
992 * added support for using EAP-SIM pseudonyms and fast re-authentication
993 * added support for EAP-AKA in the integrated EAP authenticator
994 * added support for matching EAP identity prefixes (e.g., "1"*) in EAP
995 user database to allow EAP-SIM/AKA selection without extra roundtrip
996 for EAP-Nak negotiation
997 * added support for storing EAP user password as NtPasswordHash instead
998 of plaintext password when using MSCHAP or MSCHAPv2 for
999 authentication (hash:<16-octet hex value>); added nt_password_hash
1000 tool for hashing password to generate NtPasswordHash
1002 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
1003 * driver_wired: fixed EAPOL sending to optionally use PAE group address
1004 as the destination instead of supplicant MAC address; this is
1005 disabled by default, but should be enabled with use_pae_group_addr=1
1006 in configuration file if the wired interface is used by only one
1007 device at the time (common switch configuration)
1008 * driver_madwifi: configure driver to use TKIP countermeasures in order
1009 to get correct behavior (IEEE 802.11 association failing; previously,
1010 association succeeded, but hostpad forced disassociation immediately)
1011 * driver_madwifi: added support for madwifi-ng
1014 * added support for replacing user identity from EAP with RADIUS
1015 User-Name attribute from Access-Accept message, if that is included,
1016 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
1017 tunneled identity into accounting messages when the RADIUS server
1018 does not support better way of doing this with Class attribute)
1019 * driver_madwifi: fixed EAPOL packet receive for configuration where
1020 ath# is part of a bridge interface
1021 * added a configuration file and log analyzer script for logwatch
1022 * fixed EAPOL state machine step function to process all state
1023 transitions before processing new events; this resolves a race
1024 condition in which EAPOL-Start message could trigger hostapd to send
1025 two EAP-Response/Identity frames to the authentication server
1028 * added client CA list to the TLS certificate request in order to make
1029 it easier for the client to select which certificate to use
1030 * added experimental support for EAP-PSK
1031 * added support for WE-19 (hostap, madwifi)
1034 * fixed build without CONFIG_RSN_PREAUTH
1035 * fixed FreeBSD build
1038 * fixed PMKSA caching to copy User-Name and Class attributes so that
1039 RADIUS accounting gets correct information
1040 * start RADIUS accounting only after successful completion of WPA
1041 4-Way Handshake if WPA-PSK is used
1042 * fixed PMKSA caching for the case where STA (re)associates without
1043 first disassociating
1046 * EAP-PAX is now registered as EAP type 46
1047 * fixed EAP-PAX MAC calculation
1048 * fixed EAP-PAX CK and ICK key derivation
1049 * renamed eap_authenticator configuration variable to eap_server to
1050 better match with RFC 3748 (EAP) terminology
1051 * driver_test: added support for testing hostapd with wpa_supplicant
1052 by using test driver interface without any kernel drivers or network
1056 * fixed RADIUS server initialization when only auth or acct server
1057 is configured and the other one is left empty
1058 * driver_madwifi: added support for RADIUS accounting
1059 * driver_madwifi: added preliminary support for compiling against 'BSD'
1060 branch of madwifi CVS tree
1061 * driver_madwifi: fixed pairwise key removal to allow WPA reauth
1062 without disassociation
1063 * added support for reading additional certificates from PKCS#12 files
1064 and adding them to the certificate chain
1065 * fixed RADIUS Class attribute processing to only use Access-Accept
1066 packets to update Class; previously, other RADIUS authentication
1067 packets could have cleared Class attribute
1068 * added support for more than one Class attribute in RADIUS packets
1069 * added support for verifying certificate revocation list (CRL) when
1070 using integrated EAP authenticator for EAP-TLS; new hostapd.conf
1071 options 'check_crl'; CRL must be included in the ca_cert file for now
1073 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
1074 * added support for including network information into
1075 EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
1076 (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
1077 * fixed a bug which caused some RSN pre-authentication cases to use
1078 freed memory and potentially crash hostapd
1079 * fixed private key loading for cases where passphrase is not set
1080 * added support for sending TLS alerts and aborting authentication
1081 when receiving a TLS alert
1082 * fixed WPA2 to add PMKSA cache entry when using integrated EAP
1084 * fixed PMKSA caching (EAP authentication was not skipped correctly
1085 with the new state machine changes from IEEE 802.1X draft)
1086 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
1087 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
1088 to be added to .config to include IPv6 support); for RADIUS server,
1089 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
1090 in RADIUS clients file can then use IPv6 format
1091 * added experimental support for EAP-PAX
1092 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with
1093 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
1095 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
1098 * added support for configuring a forced PEAP version based on the
1100 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
1101 to terminate authentication
1102 * fixed EAP identifier duplicate processing with the new IEEE 802.1X
1104 * clear accounting data in the driver when starting a new accounting
1106 * driver_madwifi: filter wireless events based on ifindex to allow more
1107 than one network interface to be used
1108 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
1109 setting if the packet does not pass MIC verification (e.g., due to
1110 incorrect PSK); previously, message 1/4 was not tried again if an
1111 invalid message 2/4 was received
1112 * fixed reconfiguration of RADIUS client retransmission timer when
1113 adding a new message to the pending list; previously, timer was not
1114 updated at this point and if there was a pending message with long
1115 time for the next retry, the new message needed to wait that long for
1116 its first retry, too
1119 * added support for configuring multiple allowed EAP types for Phase 2
1120 authentication (EAP-PEAP, EAP-TTLS)
1121 * fixed EAPOL-Start processing to trigger WPA reauthentication
1122 (previously, only EAPOL authentication was done)
1125 * added support for EAP-PEAP in the integrated EAP authenticator
1126 * added support for EAP-GTC in the integrated EAP authenticator
1127 * added support for configuring list of EAP methods for Phase 1 so that
1128 the integrated EAP authenticator can, e.g., use the wildcard entry
1129 for EAP-TLS and EAP-PEAP
1130 * added support for EAP-TTLS in the integrated EAP authenticator
1131 * added support for EAP-SIM in the integrated EAP authenticator
1132 * added support for using hostapd as a RADIUS authentication server
1133 with the integrated EAP authenticator taking care of EAP
1134 authentication (new hostapd.conf options: radius_server_clients and
1135 radius_server_auth_port); this is not included in default build; use
1136 CONFIG_RADIUS_SERVER=y in .config to include
1139 * removed 'daemonize' configuration file option since it has not really
1140 been used at all for more than year
1141 * driver_madwifi: fixed group key setup and added get_ssid method
1142 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator
1145 * added support for integrated EAP-TLS authentication (new hostapd.conf
1146 variables: ca_cert, server_cert, private_key, private_key_passwd);
1147 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
1148 external RADIUS server
1149 * added support for reading PKCS#12 (PFX) files (as a replacement for
1150 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
1152 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
1153 * added support for Acct-{Input,Output}-Gigawords
1154 * added support for Event-Timestamp (in RADIUS Accounting-Requests)
1155 * added support for RADIUS Authentication Client MIB (RFC2618)
1156 * added support for RADIUS Accounting Client MIB (RFC2620)
1157 * made EAP re-authentication period configurable (eap_reauth_period)
1158 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
1159 * fixed EAPOL state machine to stop if STA is removed during
1160 eapol_sm_step(); this fixes at least one segfault triggering bug with
1161 IEEE 802.11i pre-authentication
1162 * added support for multiple WPA pre-shared keys (e.g., one for each
1163 client MAC address or keys shared by a group of clients);
1164 new hostapd.conf field wpa_psk_file for setting path to a text file
1165 containing PSKs, see hostapd.wpa_psk for an example
1166 * added support for multiple driver interfaces to allow hostapd to be
1167 used with other drivers
1168 * added wired authenticator driver interface (driver=wired in
1169 hostapd.conf, see wired.conf for example configuration)
1170 * added madwifi driver interface (driver=madwifi in hostapd.conf, see
1171 madwifi.conf for example configuration; Note: include files from
1172 madwifi project is needed for building and a configuration file,
1173 .config, needs to be created in hostapd directory with
1174 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
1176 * fixed an alignment issue that could cause SHA-1 to fail on some
1177 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
1179 * fixed RADIUS reconnection after an error in sending interim
1181 * added hostapd control interface for external programs and an example
1182 CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
1183 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
1184 'hostapd_cli sta <addr>')
1185 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
1186 * added support for strict GTK rekeying (wpa_strict_rekey in
1188 * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
1189 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
1191 * added Prism54 driver interface (driver=prism54 in hostapd.conf;
1192 note: .config needs to be created in hostapd directory with
1193 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
1195 * dual-licensed hostapd (GPLv2 and BSD licenses)
1196 * fixed RADIUS accounting to generate a new session id for cases where
1197 a station reassociates without first being complete deauthenticated
1198 * fixed STA disassociation handler to mark next timeout state to
1199 deauthenticate the station, i.e., skip long wait for inactivity poll
1200 and extra disassociation, if the STA disassociates without
1202 * added integrated EAP authenticator that can be used instead of
1203 external RADIUS authentication server; currently, only EAP-MD5 is
1204 supported, so this cannot yet be used for key distribution; the EAP
1205 method interface is generic, though, so adding new EAP methods should
1206 be straightforward; new hostapd.conf variables: 'eap_authenticator'
1207 and 'eap_user_file'; this obsoletes "minimal authentication server"
1208 ('minimal_eap' in hostapd.conf) which is now removed
1209 * added support for FreeBSD and driver interface for the BSD net80211
1210 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
1211 .config); please note that some of the required kernel mods have not
1214 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
1215 * fixed some accounting cases where Accounting-Start was sent when
1216 IEEE 802.1X port was being deauthorized
1219 * modified RADIUS client to re-connect the socket in case of certain
1220 error codes that are generated when a network interface state is
1221 changes (e.g., when IP address changes or the interface is set UP)
1222 * fixed couple of cases where EAPOL state for a station was freed
1223 twice causing a segfault for hostapd
1224 * fixed couple of bugs in processing WPA deauthentication (freed data
1228 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
1229 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
1230 cases where STAs dropped multicast frames as replay attacks
1231 * added support for copying RADIUS Attribute 'Class' from
1232 authentication messages into accounting messages
1233 * send canned EAP failure if RADIUS server sends Access-Reject without
1234 EAP message (previously, Supplicant was not notified in this case)
1235 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
1236 not start EAPOL state machines if the STA selected to use WPA-PSK)
1239 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
1240 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
1241 (i.e., IEEE 802.11i/D3.0)
1242 - supports WPA-only, RSN-only, and mixed WPA/RSN mode
1243 - both WPA-PSK and WPA-RADIUS/EAP are supported
1244 - PMKSA caching and pre-authentication
1245 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
1246 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
1247 rsn_preauth, rsn_preauth_interfaces
1248 * fixed interim accounting to remove any pending accounting messages
1249 to the STA before sending a new one
1252 * added support for Acct-Interim-Interval:
1253 - draft-ietf-radius-acct-interim-01.txt
1254 - use Acct-Interim-Interval attribute from Access-Accept if local
1255 'radius_acct_interim_interval' is not set
1256 - allow different update intervals for each STA
1257 * fixed event loop to call signal handlers only after returning from
1258 the real signal handler
1259 * reset sta->timeout_next after successful association to make sure
1260 that the previously registered inactivity timer will not remove the
1261 STA immediately (e.g., if STA deauthenticates and re-associates
1262 before the timer is triggered).
1263 * added new hostapd.conf variable, nas_identifier, that can be used to
1264 add an optional RADIUS Attribute, NAS-Identifier, into authentication
1265 and accounting messages
1266 * added support for Accounting-On and Accounting-Off messages
1267 * fixed accounting session handling to send Accounting-Start only once
1268 per session and not to send Accounting-Stop if the session was not
1269 initialized properly
1270 * fixed Accounting-Stop statistics in cases where the message was
1271 previously sent after the kernel entry for the STA (and/or IEEE
1272 802.1X data) was removed
1277 Older changes up to and including v0.1.0 are included in the ChangeLog
1278 of the Host AP driver.
