only supported with driver=nl80211 for now) * fixed WPS Probe Request processing to handle missing required attribute * fixed PKCS#12 use with OpenSSL 1.0.0 * detect bridge interface automatically so that bridge parameter in hostapd.conf becomes optional (though, it may now be used to automatically add then WLAN interface into a bridge with driver=nl80211) 2009-11-21 - v0.7.0 * increased hostapd_cli ping interval to 5 seconds and made this configurable with a new command line options (-G) * driver_nl80211: use Linux socket filter to improve performance * added support for external Registrars with WPS (UPnP transport) * 802.11n: scan for overlapping BSSes before starting 20/40 MHz channel * driver_nl80211: fixed STA accounting data collection (TX/RX bytes reported correctly; TX/RX packets not yet available from kernel) * added support for WPS USBA out-of-band mechanism with USB Flash Drives (UFD) (CONFIG_WPS_UFD=y) * fixed EAPOL/EAP reauthentication when using an external RADIUS authentication server * fixed TNC with EAP-TTLS * fixed IEEE 802.11r key derivation function to match with the standard (note: this breaks interoperability with previous version) [Bug 303] * fixed SHA-256 based key derivation function to match with the standard when using CCMP (for IEEE 802.11r and IEEE 802.11w) (note: this breaks interoperability with previous version) [Bug 307] * added number of code size optimizations to remove unnecessary functionality from the program binary based on build configuration (part of this automatic; part configurable with CONFIG_NO_* build options) * use shared driver wrapper files with wpa_supplicant * driver_nl80211: multiple updates to provide support for new Linux nl80211/mac80211 functionality * updated management frame protection to use IEEE Std 802.11w-2009 * fixed number of small WPS issues and added workarounds to interoperate with common deployed broken implementations * added some IEEE 802.11n co-existence rules to disable 40 MHz channels or modify primary/secondary channels if needed based on neighboring networks * added support for NFC out-of-band mechanism with WPS * added preliminary support for IEEE 802.11r RIC processing 2009-01-06 - v0.6.7 * added support for Wi-Fi Protected Setup (WPS) (hostapd can now be configured to act as an integrated WPS Registrar and provision credentials for WPS Enrollees using PIN and PBC methods; external wireless Registrar can configure the AP, but external WLAN Manager Registrars are not supported); WPS support can be enabled by adding CONFIG_WPS=y into .config and setting the runtime configuration variables in hostapd.conf (see WPS section in the example configuration file); new hostapd_cli commands wps_pin and wps_pbc are used to configure WPS negotiation; see README-WPS for more details * added IEEE 802.11n HT capability configuration (ht_capab) * added support for generating Country IE based on nl80211 regulatory information (added if ieee80211d=1 in configuration) * fixed WEP authentication (both Open System and Shared Key) with mac80211 * added support for EAP-AKA' (draft-arkko-eap-aka-kdf) * added support for using driver_test over UDP socket * changed EAP-GPSK to use the IANA assigned EAP method type 51 * updated management frame protection to use IEEE 802.11w/D7.0 * fixed retransmission of EAP requests if no response is received 2008-11-23 - v0.6.6 * added a new configuration option, wpa_ptk_rekey, that can be used to enforce frequent PTK rekeying, e.g., to mitigate some attacks against TKIP deficiencies * updated OpenSSL code for EAP-FAST to use an updated version of the session ticket overriding API that was included into the upstream OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is needed with that version anymore) * changed channel flags configuration to read the information from the driver (e.g., via driver_nl80211 when using mac80211) instead of using hostapd as the source of the regulatory information (i.e., information from CRDA is now used with mac80211); this allows 5 GHz channels to be used with hostapd (if allowed in the current regulatory domain) * fixed EAP-TLS message processing for the last TLS message if it is large enough to require fragmentation (e.g., if a large Session Ticket data is included) * fixed listen interval configuration for nl80211 drivers 2008-11-01 - v0.6.5 * added support for SHA-256 as X.509 certificate digest when using the internal X.509/TLSv1 implementation * fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer identity lengths) * fixed internal TLSv1 implementation for abbreviated handshake (used by EAP-FAST server) * added support for setting VLAN ID for STAs based on local MAC ACL (accept_mac_file) as an alternative for RADIUS server-based configuration * updated management frame protection to use IEEE 802.11w/D6.0 (adds a new association ping to protect against unauthenticated authenticate or (re)associate request frames dropping association) * added support for using SHA256-based stronger key derivation for WPA2 (IEEE 802.11w) * added new "driver wrapper" for RADIUS-only configuration (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config) * fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2) is enabled in configuration * changed EAP-FAST configuration to use separate fields for A-ID and A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed 16-octet len binary value for better interoperability with some peer implementations; eap_fast_a_id is now configured as a hex string * driver_nl80211: Updated to match the current Linux mac80211 AP mode configuration (wireless-testing.git and Linux kernel releases starting from 2.6.29) 2008-08-10 - v0.6.4 * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2 Identity Request if identity is already known * added support for EAP Sequences in EAP-FAST Phase 2 * added support for EAP-TNC (Trusted Network Connect) (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST changes needed to run two methods in sequence (IF-T) and the IF-IMV and IF-TNCCS interfaces from TNCS) * added support for optional cryptobinding with PEAPv0 * added fragmentation support for EAP-TNC * added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled) data * added support for opportunistic key caching (OKC) 2008-02-22 - v0.6.3 * fixed Reassociation Response callback processing when using internal MLME (driver_{hostap,nl80211,test}.c) * updated FT support to use the latest draft, IEEE 802.11r/D9.0 * copy optional Proxy-State attributes into RADIUS response when acting as a RADIUS authentication server * fixed EAPOL state machine to handle a case in which no response is received from the RADIUS authentication server; previous version could have triggered a crash in some cases after a timeout * fixed EAP-SIM/AKA realm processing to allow decorated usernames to be used * added a workaround for EAP-SIM/AKA peers that include incorrect null termination in the username * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER attribute in notification messages only when using fast reauthentication * fixed EAP-SIM Start response processing for fast reauthentication case * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST} phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method 2008-01-01 - v0.6.2 * fixed EAP-SIM and EAP-AKA message parser to validate attribute lengths properly to avoid potential crash caused by invalid messages * added data structure for storing allocated buffers (struct wpabuf); this does not affect hostapd usage, but many of the APIs changed and various interfaces (e.g., EAP) is not compatible with old versions * added support for protecting EAP-AKA/Identity messages with AT_CHECKCODE (optional feature in RFC 4187) * added support for protected result indication with AT_RESULT_IND for EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1) * added support for configuring EAP-TTLS phase 2 non-EAP methods in EAP server configuration; previously all four were enabled for every phase 2 user, now all four are disabled by default and need to be enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP, TTLS-MSCHAPV2 * removed old debug printing mechanism and the related 'debug' parameter in the configuration file; debug verbosity is now set with -d (or -dd) command line arguments * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt); only shared key/password authentication is supported in this version 2007-11-24 - v0.6.1 * added experimental, integrated TLSv1 server implementation with the needed X.509/ASN.1/RSA/bignum processing (this can be enabled by setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in .config); this can be useful, e.g., if the target system does not have a suitable TLS library and a minimal code size is required * added support for EAP-FAST server method to the integrated EAP server * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest draft (draft-ietf-emu-eap-gpsk-07.txt) * added a new configuration parameter, rsn_pairwise, to allow different pairwise cipher suites to be enabled for WPA and RSN/WPA2 (note: if wpa_pairwise differs from rsn_pairwise, the driver will either need to support this or will have to use the WPA/RSN IEs from hostapd; currently, the included madwifi and bsd driver interfaces do not have support for this) * updated FT support to use the latest draft, IEEE 802.11r/D8.0 2007-05-28 - v0.6.0 * added experimental IEEE 802.11r/D6.0 support * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48 * updated EAP-PSK to use the IANA-allocated EAP type 47 * fixed EAP-PSK bit ordering of the Flags field * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs by reading wpa_psk_file [Bug 181] * fixed EAP-TTLS AVP parser processing for too short AVP lengths * fixed IPv6 connection to RADIUS accounting server * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest draft (draft-ietf-emu-eap-gpsk-04.txt) * hlr_auc_gw: read GSM triplet file into memory and rotate through the entries instead of only using the same three triplets every time (this does not work properly with tests using multiple clients, but provides bit better triplet data for testing a single client; anyway, if a better quality triplets are needed, GSM-Milenage should be used instead of hardcoded triplet file) * fixed EAP-MSCHAPv2 server to use a space between S and M parameters in Success Request [Bug 203] * added support for sending EAP-AKA Notifications in error cases * updated to use IEEE 802.11w/D2.0 for management frame protection (still experimental) * RADIUS server: added support for processing duplicate messages (retransmissions from RADIUS client) by replying with the previous reply 2006-11-24 - v0.5.6 * added support for configuring and controlling multiple BSSes per radio interface (bss= in hostapd.conf); this is only available with Devicescape and test driver interfaces * fixed PMKSA cache update in the end of successful RSN pre-authentication * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID for each STA based on RADIUS Access-Accept attributes); this requires VLAN support from the kernel driver/802.11 stack and this is currently only available with Devicescape and test driver interfaces * driver_madwifi: fixed configuration of unencrypted modes (plaintext and IEEE 802.1X without WEP) * removed STAKey handshake since PeerKey handshake has replaced it in IEEE 802.11ma and there are no known deployments of STAKey * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest draft (draft-ietf-emu-eap-gpsk-01.txt) * added preliminary implementation of IEEE 802.11w/D1.0 (management frame protection) (Note: this requires driver support to work properly.) (Note2: IEEE 802.11w is an unapproved draft and subject to change.) * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM) * hlr_auc_gw: added support for reading per-IMSI Milenage keys and parameters from a text file to make it possible to implement proper GSM/UMTS authentication server for multiple SIM/USIM cards using EAP-SIM/EAP-AKA * fixed session timeout processing with drivers that do not use ieee802_11.c (e.g., madwifi) 2006-08-27 - v0.5.5 * added 'hostapd_cli new_sta ' command for adding a new STA into hostapd (e.g., to initialize wired network authentication based on an external signal) * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when using WPA2 even if PMKSA caching is not used * added -P argument for hostapd to write the current process id into a file * added support for RADIUS Authentication Server MIB (RFC 2619) 2006-06-20 - v0.5.4 * fixed nt_password_hash build [Bug 144] * added PeerKey handshake implementation for IEEE 802.11e direct link setup (DLS) to replace STAKey handshake * added support for EAP Generalized Pre-Shared Key (EAP-GPSK, draft-clancy-emu-eap-shared-secret-00.txt) * fixed a segmentation fault when RSN pre-authentication was completed successfully [Bug 152] 2006-04-27 - v0.5.3 * do not build nt_password_hash and hlr_auc_gw by default to avoid requiring a TLS library for a successful build; these programs can be build with 'make nt_password_hash' and 'make hlr_auc_gw' * added a new configuration option, eapol_version, that can be used to set EAPOL version to 1 (default is 2) to work around broken client implementations that drop EAPOL frames which use version number 2 [Bug 89] * added support for EAP-SAKE (no EAP method number allocated yet, so this is using the same experimental type 255 as EAP-PSK) * fixed EAP-MSCHAPv2 message length validation 2006-03-19 - v0.5.2 * fixed stdarg use in hostapd_logger(): if both stdout and syslog logging was enabled, hostapd could trigger a segmentation fault in vsyslog on some CPU -- C library combinations * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external program to make it easier to use for implementing real SS7 gateway; eap_sim_db is not anymore used as a file name for GSM authentication triplets; instead, it is path to UNIX domain socket that will be used to communicate with the external gateway program (e.g., hlr_auc_gw) * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses local information (GSM authentication triplets from a text file and hardcoded AKA authentication data); this can be used to test EAP-SIM and EAP-AKA * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw to make it possible to test EAP-AKA with real USIM cards (this is disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw to enable this) * driver_madwifi: added support for getting station RSN IE from madwifi-ng svn r1453 and newer; this fixes RSN that was apparently broken with earlier change (r1357) in the driver * changed EAP method registration to use a dynamic list of methods instead of a static list generated at build time * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE) [Bug 125] * added ap_max_inactivity configuration parameter 2006-01-29 - v0.5.1 * driver_test: added better support for multiple APs and STAs by using a directory with sockets that include MAC address for each device in the name (test_socket=DIR:/tmp/test) * added support for EAP expanded type (vendor specific EAP methods) 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases) * added experimental STAKey handshake implementation for IEEE 802.11e direct link setup (DLS); note: this is disabled by default in both build and runtime configuration (can be enabled with CONFIG_STAKEY=y and stakey=1) * added support for EAP methods to use callbacks to external programs by buffering a pending request and processing it after the EAP method is ready to continue * improved EAP-SIM database interface to allow external request to GSM HLR/AuC without blocking hostapd process * added support for using EAP-SIM pseudonyms and fast re-authentication * added support for EAP-AKA in the integrated EAP authenticator * added support for matching EAP identity prefixes (e.g., "1"*) in EAP user database to allow EAP-SIM/AKA selection without extra roundtrip for EAP-Nak negotiation * added support for storing EAP user password as NtPasswordHash instead of plaintext password when using MSCHAP or MSCHAPv2 for authentication (hash:<16-octet hex value>); added nt_password_hash tool for hashing password to generate NtPasswordHash 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases) * driver_wired: fixed EAPOL sending to optionally use PAE group address as the destination instead of supplicant MAC address; this is disabled by default, but should be enabled with use_pae_group_addr=1 in configuration file if the wired interface is used by only one device at the time (common switch configuration) * driver_madwifi: configure driver to use TKIP countermeasures in order to get correct behavior (IEEE 802.11 association failing; previously, association succeeded, but hostpad forced disassociation immediately) * driver_madwifi: added support for madwifi-ng 2005-10-27 - v0.4.6 * added support for replacing user identity from EAP with RADIUS User-Name attribute from Access-Accept message, if that is included, for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get tunneled identity into accounting messages when the RADIUS server does not support better way of doing this with Class attribute) * driver_madwifi: fixed EAPOL packet receive for configuration where ath# is part of a bridge interface * added a configuration file and log analyzer script for logwatch * fixed EAPOL state machine step function to process all state transitions before processing new events; this resolves a race condition in which EAPOL-Start message could trigger hostapd to send two EAP-Response/Identity frames to the authentication server 2005-09-25 - v0.4.5 * added client CA list to the TLS certificate request in order to make it easier for the client to select which certificate to use * added experimental support for EAP-PSK * added support for WE-19 (hostap, madwifi) 2005-08-21 - v0.4.4 * fixed build without CONFIG_RSN_PREAUTH * fixed FreeBSD build 2005-06-26 - v0.4.3 * fixed PMKSA caching to copy User-Name and Class attributes so that RADIUS accounting gets correct information * start RADIUS accounting only after successful completion of WPA 4-Way Handshake if WPA-PSK is used * fixed PMKSA caching for the case where STA (re)associates without first disassociating 2005-06-12 - v0.4.2 * EAP-PAX is now registered as EAP type 46 * fixed EAP-PAX MAC calculation * fixed EAP-PAX CK and ICK key derivation * renamed eap_authenticator configuration variable to eap_server to better match with RFC 3748 (EAP) terminology * driver_test: added support for testing hostapd with wpa_supplicant by using test driver interface without any kernel drivers or network cards 2005-05-22 - v0.4.1 * fixed RADIUS server initialization when only auth or acct server is configured and the other one is left empty * driver_madwifi: added support for RADIUS accounting * driver_madwifi: added preliminary support for compiling against 'BSD' branch of madwifi CVS tree * driver_madwifi: fixed pairwise key removal to allow WPA reauth without disassociation * added support for reading additional certificates from PKCS#12 files and adding them to the certificate chain * fixed RADIUS Class attribute processing to only use Access-Accept packets to update Class; previously, other RADIUS authentication packets could have cleared Class attribute * added support for more than one Class attribute in RADIUS packets * added support for verifying certificate revocation list (CRL) when using integrated EAP authenticator for EAP-TLS; new hostapd.conf options 'check_crl'; CRL must be included in the ca_cert file for now 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases) * added support for including network information into EAP-Request/Identity message (ASCII-0 (nul) in eap_message) (e.g., to implement draft-adrange-eap-network-discovery-07.txt) * fixed a bug which caused some RSN pre-authentication cases to use freed memory and potentially crash hostapd * fixed private key loading for cases where passphrase is not set * added support for sending TLS alerts and aborting authentication when receiving a TLS alert * fixed WPA2 to add PMKSA cache entry when using integrated EAP authenticator * fixed PMKSA caching (EAP authentication was not skipped correctly with the new state machine changes from IEEE 802.1X draft) * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr, and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs to be added to .config to include IPv6 support); for RADIUS server, radius_server_ipv6=1 needs to be set in hostapd.conf and addresses in RADIUS clients file can then use IPv6 format * added experimental support for EAP-PAX * replaced hostapd control interface library (hostapd_ctrl.[ch]) with the same implementation that wpa_supplicant is using (wpa_ctrl.[ch]) 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases) 2005-01-23 - v0.3.5 * added support for configuring a forced PEAP version based on the Phase 1 identity * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV to terminate authentication * fixed EAP identifier duplicate processing with the new IEEE 802.1X draft * clear accounting data in the driver when starting a new accounting session * driver_madwifi: filter wireless events based on ifindex to allow more than one network interface to be used * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt setting if the packet does not pass MIC verification (e.g., due to incorrect PSK); previously, message 1/4 was not tried again if an invalid message 2/4 was received * fixed reconfiguration of RADIUS client retransmission timer when adding a new message to the pending list; previously, timer was not updated at this point and if there was a pending message with long time for the next retry, the new message needed to wait that long for its first retry, too 2005-01-09 - v0.3.4 * added support for configuring multiple allowed EAP types for Phase 2 authentication (EAP-PEAP, EAP-TTLS) * fixed EAPOL-Start processing to trigger WPA reauthentication (previously, only EAPOL authentication was done) 2005-01-02 - v0.3.3 * added support for EAP-PEAP in the integrated EAP authenticator * added support for EAP-GTC in the integrated EAP authenticator * added support for configuring list of EAP methods for Phase 1 so that the integrated EAP authenticator can, e.g., use the wildcard entry for EAP-TLS and EAP-PEAP * added support for EAP-TTLS in the integrated EAP authenticator * added support for EAP-SIM in the integrated EAP authenticator * added support for using hostapd as a RADIUS authentication server with the integrated EAP authenticator taking care of EAP authentication (new hostapd.conf options: radius_server_clients and radius_server_auth_port); this is not included in default build; use CONFIG_RADIUS_SERVER=y in .config to include 2004-12-19 - v0.3.2 * removed 'daemonize' configuration file option since it has not really been used at all for more than year * driver_madwifi: fixed group key setup and added get_ssid method * added support for EAP-MSCHAPv2 in the integrated EAP authenticator 2004-12-12 - v0.3.1 * added support for integrated EAP-TLS authentication (new hostapd.conf variables: ca_cert, server_cert, private_key, private_key_passwd); this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without external RADIUS server * added support for reading PKCS#12 (PFX) files (as a replacement for PEM/DER) to get certificate and private key (CONFIG_PKCS12) 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases) * added support for Acct-{Input,Output}-Gigawords * added support for Event-Timestamp (in RADIUS Accounting-Requests) * added support for RADIUS Authentication Client MIB (RFC2618) * added support for RADIUS Accounting Client MIB (RFC2620) * made EAP re-authentication period configurable (eap_reauth_period) * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication * fixed EAPOL state machine to stop if STA is removed during eapol_sm_step(); this fixes at least one segfault triggering bug with IEEE 802.11i pre-authentication * added support for multiple WPA pre-shared keys (e.g., one for each client MAC address or keys shared by a group of clients); new hostapd.conf field wpa_psk_file for setting path to a text file containing PSKs, see hostapd.wpa_psk for an example * added support for multiple driver interfaces to allow hostapd to be used with other drivers * added wired authenticator driver interface (driver=wired in hostapd.conf, see wired.conf for example configuration) * added madwifi driver interface (driver=madwifi in hostapd.conf, see madwifi.conf for example configuration; Note: include files from madwifi project is needed for building and a configuration file, .config, needs to be created in hostapd directory with CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd build) * fixed an alignment issue that could cause SHA-1 to fail on some platforms (e.g., Intel ixp425 with a compiler that does not 32-bit align variables) * fixed RADIUS reconnection after an error in sending interim accounting packets * added hostapd control interface for external programs and an example CLI, hostapd_cli (like wpa_cli for wpa_supplicant) * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib', 'hostapd_cli sta ') * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11) * added support for strict GTK rekeying (wpa_strict_rekey in hostapd.conf) * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178 (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to IEEE 802.11F-2003) * added Prism54 driver interface (driver=prism54 in hostapd.conf; note: .config needs to be created in hostapd directory with CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd build) * dual-licensed hostapd (GPLv2 and BSD licenses) * fixed RADIUS accounting to generate a new session id for cases where a station reassociates without first being complete deauthenticated * fixed STA disassociation handler to mark next timeout state to deauthenticate the station, i.e., skip long wait for inactivity poll and extra disassociation, if the STA disassociates without deauthenticating * added integrated EAP authenticator that can be used instead of external RADIUS authentication server; currently, only EAP-MD5 is supported, so this cannot yet be used for key distribution; the EAP method interface is generic, though, so adding new EAP methods should be straightforward; new hostapd.conf variables: 'eap_authenticator' and 'eap_user_file'; this obsoletes "minimal authentication server" ('minimal_eap' in hostapd.conf) which is now removed * added support for FreeBSD and driver interface for the BSD net80211 layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in .config); please note that some of the required kernel mods have not yet been committed 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases) * fixed some accounting cases where Accounting-Start was sent when IEEE 802.1X port was being deauthorized 2004-06-20 - v0.2.3 * modified RADIUS client to re-connect the socket in case of certain error codes that are generated when a network interface state is changes (e.g., when IP address changes or the interface is set UP) * fixed couple of cases where EAPOL state for a station was freed twice causing a segfault for hostapd * fixed couple of bugs in processing WPA deauthentication (freed data was used) 2004-05-31 - v0.2.2 * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM) * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix cases where STAs dropped multicast frames as replay attacks * added support for copying RADIUS Attribute 'Class' from authentication messages into accounting messages * send canned EAP failure if RADIUS server sends Access-Reject without EAP message (previously, Supplicant was not notified in this case) * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do not start EAPOL state machines if the STA selected to use WPA-PSK) 2004-05-06 - v0.2.1 * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA (i.e., IEEE 802.11i/D3.0) - supports WPA-only, RSN-only, and mixed WPA/RSN mode - both WPA-PSK and WPA-RADIUS/EAP are supported - PMKSA caching and pre-authentication - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase, wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey, rsn_preauth, rsn_preauth_interfaces * fixed interim accounting to remove any pending accounting messages to the STA before sending a new one 2004-02-15 - v0.2.0 * added support for Acct-Interim-Interval: - draft-ietf-radius-acct-interim-01.txt - use Acct-Interim-Interval attribute from Access-Accept if local 'radius_acct_interim_interval' is not set - allow different update intervals for each STA * fixed event loop to call signal handlers only after returning from the real signal handler * reset sta->timeout_next after successful association to make sure that the previously registered inactivity timer will not remove the STA immediately (e.g., if STA deauthenticates and re-associates before the timer is triggered). * added new hostapd.conf variable, nas_identifier, that can be used to add an optional RADIUS Attribute, NAS-Identifier, into authentication and accounting messages * added support for Accounting-On and Accounting-Off messages * fixed accounting session handling to send Accounting-Start only once per session and not to send Accounting-Stop if the session was not initialized properly * fixed Accounting-Stop statistics in cases where the message was previously sent after the kernel entry for the STA (and/or IEEE 802.1X data) was removed Note: Older changes up to and including v0.1.0 are included in the ChangeLog of the Host AP driver.
