517 phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method
520 * fixed EAP-SIM and EAP-AKA message parser to validate attribute
521 lengths properly to avoid potential crash caused by invalid messages
522 * added data structure for storing allocated buffers (struct wpabuf);
523 this does not affect hostapd usage, but many of the APIs changed
524 and various interfaces (e.g., EAP) is not compatible with old
526 * added support for protecting EAP-AKA/Identity messages with
527 AT_CHECKCODE (optional feature in RFC 4187)
528 * added support for protected result indication with AT_RESULT_IND for
529 EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1)
530 * added support for configuring EAP-TTLS phase 2 non-EAP methods in
531 EAP server configuration; previously all four were enabled for every
532 phase 2 user, now all four are disabled by default and need to be
533 enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP,
535 * removed old debug printing mechanism and the related 'debug'
536 parameter in the configuration file; debug verbosity is now set with
537 -d (or -dd) command line arguments
538 * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
539 only shared key/password authentication is supported in this version
542 * added experimental, integrated TLSv1 server implementation with the
543 needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
544 setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
545 .config); this can be useful, e.g., if the target system does not
546 have a suitable TLS library and a minimal code size is required
547 * added support for EAP-FAST server method to the integrated EAP
549 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
550 draft (draft-ietf-emu-eap-gpsk-07.txt)
551 * added a new configuration parameter, rsn_pairwise, to allow different
552 pairwise cipher suites to be enabled for WPA and RSN/WPA2
553 (note: if wpa_pairwise differs from rsn_pairwise, the driver will
554 either need to support this or will have to use the WPA/RSN IEs from
555 hostapd; currently, the included madwifi and bsd driver interfaces do
556 not have support for this)
557 * updated FT support to use the latest draft, IEEE 802.11r/D8.0
560 * added experimental IEEE 802.11r/D6.0 support
561 * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
562 * updated EAP-PSK to use the IANA-allocated EAP type 47
563 * fixed EAP-PSK bit ordering of the Flags field
564 * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
565 by reading wpa_psk_file [Bug 181]
566 * fixed EAP-TTLS AVP parser processing for too short AVP lengths
567 * fixed IPv6 connection to RADIUS accounting server
568 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
569 draft (draft-ietf-emu-eap-gpsk-04.txt)
570 * hlr_auc_gw: read GSM triplet file into memory and rotate through the
571 entries instead of only using the same three triplets every time
572 (this does not work properly with tests using multiple clients, but
573 provides bit better triplet data for testing a single client; anyway,
574 if a better quality triplets are needed, GSM-Milenage should be used
575 instead of hardcoded triplet file)
576 * fixed EAP-MSCHAPv2 server to use a space between S and M parameters
577 in Success Request [Bug 203]
578 * added support for sending EAP-AKA Notifications in error cases
579 * updated to use IEEE 802.11w/D2.0 for management frame protection
581 * RADIUS server: added support for processing duplicate messages
582 (retransmissions from RADIUS client) by replying with the previous
586 * added support for configuring and controlling multiple BSSes per
587 radio interface (bss=<ifname> in hostapd.conf); this is only
588 available with Devicescape and test driver interfaces
589 * fixed PMKSA cache update in the end of successful RSN
591 * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
592 for each STA based on RADIUS Access-Accept attributes); this requires
593 VLAN support from the kernel driver/802.11 stack and this is
594 currently only available with Devicescape and test driver interfaces
595 * driver_madwifi: fixed configuration of unencrypted modes (plaintext
596 and IEEE 802.1X without WEP)
597 * removed STAKey handshake since PeerKey handshake has replaced it in
598 IEEE 802.11ma and there are no known deployments of STAKey
599 * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
600 draft (draft-ietf-emu-eap-gpsk-01.txt)
601 * added preliminary implementation of IEEE 802.11w/D1.0 (management
603 (Note: this requires driver support to work properly.)
604 (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
605 * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
606 * hlr_auc_gw: added support for reading per-IMSI Milenage keys and
607 parameters from a text file to make it possible to implement proper
608 GSM/UMTS authentication server for multiple SIM/USIM cards using
610 * fixed session timeout processing with drivers that do not use
611 ieee802_11.c (e.g., madwifi)
614 * added 'hostapd_cli new_sta <addr>' command for adding a new STA into
615 hostapd (e.g., to initialize wired network authentication based on an
617 * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
618 using WPA2 even if PMKSA caching is not used
619 * added -P<pid file> argument for hostapd to write the current process
621 * added support for RADIUS Authentication Server MIB (RFC 2619)
624 * fixed nt_password_hash build [Bug 144]
625 * added PeerKey handshake implementation for IEEE 802.11e
626 direct link setup (DLS) to replace STAKey handshake
627 * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
628 draft-clancy-emu-eap-shared-secret-00.txt)
629 * fixed a segmentation fault when RSN pre-authentication was completed
630 successfully [Bug 152]
633 * do not build nt_password_hash and hlr_auc_gw by default to avoid
634 requiring a TLS library for a successful build; these programs can be
635 build with 'make nt_password_hash' and 'make hlr_auc_gw'
636 * added a new configuration option, eapol_version, that can be used to
637 set EAPOL version to 1 (default is 2) to work around broken client
638 implementations that drop EAPOL frames which use version number 2
640 * added support for EAP-SAKE (no EAP method number allocated yet, so
641 this is using the same experimental type 255 as EAP-PSK)
642 * fixed EAP-MSCHAPv2 message length validation
645 * fixed stdarg use in hostapd_logger(): if both stdout and syslog
646 logging was enabled, hostapd could trigger a segmentation fault in
647 vsyslog on some CPU -- C library combinations
648 * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
649 program to make it easier to use for implementing real SS7 gateway;
650 eap_sim_db is not anymore used as a file name for GSM authentication
651 triplets; instead, it is path to UNIX domain socket that will be used
652 to communicate with the external gateway program (e.g., hlr_auc_gw)
653 * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
654 local information (GSM authentication triplets from a text file and
655 hardcoded AKA authentication data); this can be used to test EAP-SIM
657 * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
658 to make it possible to test EAP-AKA with real USIM cards (this is
659 disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
661 * driver_madwifi: added support for getting station RSN IE from
662 madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
663 broken with earlier change (r1357) in the driver
664 * changed EAP method registration to use a dynamic list of methods
665 instead of a static list generated at build time
666 * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
668 * added ap_max_inactivity configuration parameter
671 * driver_test: added better support for multiple APs and STAs by using
672 a directory with sockets that include MAC address for each device in
673 the name (test_socket=DIR:/tmp/test)
674 * added support for EAP expanded type (vendor specific EAP methods)
676 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
677 * added experimental STAKey handshake implementation for IEEE 802.11e
678 direct link setup (DLS); note: this is disabled by default in both
679 build and runtime configuration (can be enabled with CONFIG_STAKEY=y
681 * added support for EAP methods to use callbacks to external programs
682 by buffering a pending request and processing it after the EAP method
684 * improved EAP-SIM database interface to allow external request to GSM
685 HLR/AuC without blocking hostapd process
686 * added support for using EAP-SIM pseudonyms and fast re-authentication
687 * added support for EAP-AKA in the integrated EAP authenticator
688 * added support for matching EAP identity prefixes (e.g., "1"*) in EAP
689 user database to allow EAP-SIM/AKA selection without extra roundtrip
690 for EAP-Nak negotiation
691 * added support for storing EAP user password as NtPasswordHash instead
692 of plaintext password when using MSCHAP or MSCHAPv2 for
693 authentication (hash:<16-octet hex value>); added nt_password_hash
694 tool for hashing password to generate NtPasswordHash
696 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
697 * driver_wired: fixed EAPOL sending to optionally use PAE group address
698 as the destination instead of supplicant MAC address; this is
699 disabled by default, but should be enabled with use_pae_group_addr=1
700 in configuration file if the wired interface is used by only one
701 device at the time (common switch configuration)
702 * driver_madwifi: configure driver to use TKIP countermeasures in order
703 to get correct behavior (IEEE 802.11 association failing; previously,
704 association succeeded, but hostpad forced disassociation immediately)
705 * driver_madwifi: added support for madwifi-ng
708 * added support for replacing user identity from EAP with RADIUS
709 User-Name attribute from Access-Accept message, if that is included,
710 for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
711 tunneled identity into accounting messages when the RADIUS server
712 does not support better way of doing this with Class attribute)
713 * driver_madwifi: fixed EAPOL packet receive for configuration where
714 ath# is part of a bridge interface
715 * added a configuration file and log analyzer script for logwatch
716 * fixed EAPOL state machine step function to process all state
717 transitions before processing new events; this resolves a race
718 condition in which EAPOL-Start message could trigger hostapd to send
719 two EAP-Response/Identity frames to the authentication server
722 * added client CA list to the TLS certificate request in order to make
723 it easier for the client to select which certificate to use
724 * added experimental support for EAP-PSK
725 * added support for WE-19 (hostap, madwifi)
728 * fixed build without CONFIG_RSN_PREAUTH
729 * fixed FreeBSD build
732 * fixed PMKSA caching to copy User-Name and Class attributes so that
733 RADIUS accounting gets correct information
734 * start RADIUS accounting only after successful completion of WPA
735 4-Way Handshake if WPA-PSK is used
736 * fixed PMKSA caching for the case where STA (re)associates without
740 * EAP-PAX is now registered as EAP type 46
741 * fixed EAP-PAX MAC calculation
742 * fixed EAP-PAX CK and ICK key derivation
743 * renamed eap_authenticator configuration variable to eap_server to
744 better match with RFC 3748 (EAP) terminology
745 * driver_test: added support for testing hostapd with wpa_supplicant
746 by using test driver interface without any kernel drivers or network
750 * fixed RADIUS server initialization when only auth or acct server
751 is configured and the other one is left empty
752 * driver_madwifi: added support for RADIUS accounting
753 * driver_madwifi: added preliminary support for compiling against 'BSD'
754 branch of madwifi CVS tree
755 * driver_madwifi: fixed pairwise key removal to allow WPA reauth
756 without disassociation
757 * added support for reading additional certificates from PKCS#12 files
758 and adding them to the certificate chain
759 * fixed RADIUS Class attribute processing to only use Access-Accept
760 packets to update Class; previously, other RADIUS authentication
761 packets could have cleared Class attribute
762 * added support for more than one Class attribute in RADIUS packets
763 * added support for verifying certificate revocation list (CRL) when
764 using integrated EAP authenticator for EAP-TLS; new hostapd.conf
765 options 'check_crl'; CRL must be included in the ca_cert file for now
767 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
768 * added support for including network information into
769 EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
770 (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
771 * fixed a bug which caused some RSN pre-authentication cases to use
772 freed memory and potentially crash hostapd
773 * fixed private key loading for cases where passphrase is not set
774 * added support for sending TLS alerts and aborting authentication
775 when receiving a TLS alert
776 * fixed WPA2 to add PMKSA cache entry when using integrated EAP
778 * fixed PMKSA caching (EAP authentication was not skipped correctly
779 with the new state machine changes from IEEE 802.1X draft)
780 * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
781 and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
782 to be added to .config to include IPv6 support); for RADIUS server,
783 radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
784 in RADIUS clients file can then use IPv6 format
785 * added experimental support for EAP-PAX
786 * replaced hostapd control interface library (hostapd_ctrl.[ch]) with
787 the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
789 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
792 * added support for configuring a forced PEAP version based on the
794 * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
795 to terminate authentication
796 * fixed EAP identifier duplicate processing with the new IEEE 802.1X
798 * clear accounting data in the driver when starting a new accounting
800 * driver_madwifi: filter wireless events based on ifindex to allow more
801 than one network interface to be used
802 * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
803 setting if the packet does not pass MIC verification (e.g., due to
804 incorrect PSK); previously, message 1/4 was not tried again if an
805 invalid message 2/4 was received
806 * fixed reconfiguration of RADIUS client retransmission timer when
807 adding a new message to the pending list; previously, timer was not
808 updated at this point and if there was a pending message with long
809 time for the next retry, the new message needed to wait that long for
813 * added support for configuring multiple allowed EAP types for Phase 2
814 authentication (EAP-PEAP, EAP-TTLS)
815 * fixed EAPOL-Start processing to trigger WPA reauthentication
816 (previously, only EAPOL authentication was done)
819 * added support for EAP-PEAP in the integrated EAP authenticator
820 * added support for EAP-GTC in the integrated EAP authenticator
821 * added support for configuring list of EAP methods for Phase 1 so that
822 the integrated EAP authenticator can, e.g., use the wildcard entry
823 for EAP-TLS and EAP-PEAP
824 * added support for EAP-TTLS in the integrated EAP authenticator
825 * added support for EAP-SIM in the integrated EAP authenticator
826 * added support for using hostapd as a RADIUS authentication server
827 with the integrated EAP authenticator taking care of EAP
828 authentication (new hostapd.conf options: radius_server_clients and
829 radius_server_auth_port); this is not included in default build; use
830 CONFIG_RADIUS_SERVER=y in .config to include
833 * removed 'daemonize' configuration file option since it has not really
834 been used at all for more than year
835 * driver_madwifi: fixed group key setup and added get_ssid method
836 * added support for EAP-MSCHAPv2 in the integrated EAP authenticator
839 * added support for integrated EAP-TLS authentication (new hostapd.conf
840 variables: ca_cert, server_cert, private_key, private_key_passwd);
841 this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
842 external RADIUS server
843 * added support for reading PKCS#12 (PFX) files (as a replacement for
844 PEM/DER) to get certificate and private key (CONFIG_PKCS12)
846 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
847 * added support for Acct-{Input,Output}-Gigawords
848 * added support for Event-Timestamp (in RADIUS Accounting-Requests)
849 * added support for RADIUS Authentication Client MIB (RFC2618)
850 * added support for RADIUS Accounting Client MIB (RFC2620)
851 * made EAP re-authentication period configurable (eap_reauth_period)
852 * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
853 * fixed EAPOL state machine to stop if STA is removed during
854 eapol_sm_step(); this fixes at least one segfault triggering bug with
855 IEEE 802.11i pre-authentication
856 * added support for multiple WPA pre-shared keys (e.g., one for each
857 client MAC address or keys shared by a group of clients);
858 new hostapd.conf field wpa_psk_file for setting path to a text file
859 containing PSKs, see hostapd.wpa_psk for an example
860 * added support for multiple driver interfaces to allow hostapd to be
861 used with other drivers
862 * added wired authenticator driver interface (driver=wired in
863 hostapd.conf, see wired.conf for example configuration)
864 * added madwifi driver interface (driver=madwifi in hostapd.conf, see
865 madwifi.conf for example configuration; Note: include files from
866 madwifi project is needed for building and a configuration file,
867 .config, needs to be created in hostapd directory with
868 CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
870 * fixed an alignment issue that could cause SHA-1 to fail on some
871 platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
873 * fixed RADIUS reconnection after an error in sending interim
875 * added hostapd control interface for external programs and an example
876 CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
877 * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
878 'hostapd_cli sta <addr>')
879 * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
880 * added support for strict GTK rekeying (wpa_strict_rekey in
882 * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
883 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
885 * added Prism54 driver interface (driver=prism54 in hostapd.conf;
886 note: .config needs to be created in hostapd directory with
887 CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
889 * dual-licensed hostapd (GPLv2 and BSD licenses)
890 * fixed RADIUS accounting to generate a new session id for cases where
891 a station reassociates without first being complete deauthenticated
892 * fixed STA disassociation handler to mark next timeout state to
893 deauthenticate the station, i.e., skip long wait for inactivity poll
894 and extra disassociation, if the STA disassociates without
896 * added integrated EAP authenticator that can be used instead of
897 external RADIUS authentication server; currently, only EAP-MD5 is
898 supported, so this cannot yet be used for key distribution; the EAP
899 method interface is generic, though, so adding new EAP methods should
900 be straightforward; new hostapd.conf variables: 'eap_authenticator'
901 and 'eap_user_file'; this obsoletes "minimal authentication server"
902 ('minimal_eap' in hostapd.conf) which is now removed
903 * added support for FreeBSD and driver interface for the BSD net80211
904 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
905 .config); please note that some of the required kernel mods have not
908 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
909 * fixed some accounting cases where Accounting-Start was sent when
910 IEEE 802.1X port was being deauthorized
913 * modified RADIUS client to re-connect the socket in case of certain
914 error codes that are generated when a network interface state is
915 changes (e.g., when IP address changes or the interface is set UP)
916 * fixed couple of cases where EAPOL state for a station was freed
917 twice causing a segfault for hostapd
918 * fixed couple of bugs in processing WPA deauthentication (freed data
922 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
923 * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
924 cases where STAs dropped multicast frames as replay attacks
925 * added support for copying RADIUS Attribute 'Class' from
926 authentication messages into accounting messages
927 * send canned EAP failure if RADIUS server sends Access-Reject without
928 EAP message (previously, Supplicant was not notified in this case)
929 * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
930 not start EAPOL state machines if the STA selected to use WPA-PSK)
933 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
934 - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
935 (i.e., IEEE 802.11i/D3.0)
936 - supports WPA-only, RSN-only, and mixed WPA/RSN mode
937 - both WPA-PSK and WPA-RADIUS/EAP are supported
938 - PMKSA caching and pre-authentication
939 - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
940 wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
941 rsn_preauth, rsn_preauth_interfaces
942 * fixed interim accounting to remove any pending accounting messages
943 to the STA before sending a new one
946 * added support for Acct-Interim-Interval:
947 - draft-ietf-radius-acct-interim-01.txt
948 - use Acct-Interim-Interval attribute from Access-Accept if local
949 'radius_acct_interim_interval' is not set
950 - allow different update intervals for each STA
951 * fixed event loop to call signal handlers only after returning from
952 the real signal handler
953 * reset sta->timeout_next after successful association to make sure
954 that the previously registered inactivity timer will not remove the
955 STA immediately (e.g., if STA deauthenticates and re-associates
956 before the timer is triggered).
957 * added new hostapd.conf variable, nas_identifier, that can be used to
958 add an optional RADIUS Attribute, NAS-Identifier, into authentication
959 and accounting messages
960 * added support for Accounting-On and Accounting-Off messages
961 * fixed accounting session handling to send Accounting-Start only once
962 per session and not to send Accounting-Stop if the session was not
964 * fixed Accounting-Stop statistics in cases where the message was
965 previously sent after the kernel entry for the STA (and/or IEEE
966 802.1X data) was removed
971 Older changes up to and including v0.1.0 are included in the ChangeLog
972 of the Host AP driver.
