hostapd/ChangeLog

   1 ChangeLog for hostapd
   2
   3 ????-??-?? - v0.7.0
   4         * increased hostapd_cli ping interval to 5 seconds and made this
   5           configurable with a new command line options (-G<seconds>)
   6         * driver_nl80211: use Linux socket filter to improve performance
   7         * added support for external Registrars with WPS (UPnP transport)
   8         * 802.11n: scan for overlapping BSSes before starting 20/40 MHz channel
   9         * driver_nl80211: fixed STA accounting data collection (TX/RX bytes
  10           reported correctly; TX/RX packets not yet available from kernel)
  11         * added support for WPS USBA out-of-band mechanism with USB Flash
  12           Drives (UFD) (CONFIG_WPS_UFD=y)
  13         * fixed EAPOL/EAP reauthentication when using an external RADIUS
  14           authentication server
  15         * fixed TNC with EAP-TTLS
  16         * fixed IEEE 802.11r key derivation function to match with the standard
  17           (note: this breaks interoperability with previous version) [Bug 303]
  18
  19 2009-01-06 - v0.6.7
  20         * added support for Wi-Fi Protected Setup (WPS)
  21           (hostapd can now be configured to act as an integrated WPS Registrar
  22           and provision credentials for WPS Enrollees using PIN and PBC
  23           methods; external wireless Registrar can configure the AP, but
  24           external WLAN Manager Registrars are not supported); WPS support can
  25           be enabled by adding CONFIG_WPS=y into .config and setting the
  26           runtime configuration variables in hostapd.conf (see WPS section in
  27           the example configuration file); new hostapd_cli commands wps_pin and
  28           wps_pbc are used to configure WPS negotiation; see README-WPS for
  29           more details
  30         * added IEEE 802.11n HT capability configuration (ht_capab)
  31         * added support for generating Country IE based on nl80211 regulatory
  32           information (added if ieee80211d=1 in configuration)
  33         * fixed WEP authentication (both Open System and Shared Key) with
  34           mac80211
  35         * added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
  36         * added support for using driver_test over UDP socket
  37         * changed EAP-GPSK to use the IANA assigned EAP method type 51
  38         * updated management frame protection to use IEEE 802.11w/D7.0
  39         * fixed retransmission of EAP requests if no response is received
  40
  41 2008-11-23 - v0.6.6
  42         * added a new configuration option, wpa_ptk_rekey, that can be used to
  43           enforce frequent PTK rekeying, e.g., to mitigate some attacks against
  44           TKIP deficiencies
  45         * updated OpenSSL code for EAP-FAST to use an updated version of the
  46           session ticket overriding API that was included into the upstream
  47           OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
  48           needed with that version anymore)
  49         * changed channel flags configuration to read the information from
  50           the driver (e.g., via driver_nl80211 when using mac80211) instead of
  51           using hostapd as the source of the regulatory information (i.e.,
  52           information from CRDA is now used with mac80211); this allows 5 GHz
  53           channels to be used with hostapd (if allowed in the current
  54           regulatory domain)
  55         * fixed EAP-TLS message processing for the last TLS message if it is
  56           large enough to require fragmentation (e.g., if a large Session
  57           Ticket data is included)
  58         * fixed listen interval configuration for nl80211 drivers
  59
  60 2008-11-01 - v0.6.5
  61         * added support for SHA-256 as X.509 certificate digest when using the
  62           internal X.509/TLSv1 implementation
  63         * fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer
  64           identity lengths)
  65         * fixed internal TLSv1 implementation for abbreviated handshake (used
  66           by EAP-FAST server)
  67         * added support for setting VLAN ID for STAs based on local MAC ACL
  68           (accept_mac_file) as an alternative for RADIUS server-based
  69           configuration
  70         * updated management frame protection to use IEEE 802.11w/D6.0
  71           (adds a new association ping to protect against unauthenticated
  72           authenticate or (re)associate request frames dropping association)
  73         * added support for using SHA256-based stronger key derivation for WPA2
  74           (IEEE 802.11w)
  75         * added new "driver wrapper" for RADIUS-only configuration
  76           (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config)
  77         * fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2)
  78           is enabled in configuration
  79         * changed EAP-FAST configuration to use separate fields for A-ID and
  80           A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed
  81           16-octet len binary value for better interoperability with some peer
  82           implementations; eap_fast_a_id is now configured as a hex string
  83         * driver_nl80211: Updated to match the current Linux mac80211 AP mode
  84           configuration (wireless-testing.git and Linux kernel releases
  85           starting from 2.6.29)
  86
  87 2008-08-10 - v0.6.4
  88         * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2
  89           Identity Request if identity is already known
  90         * added support for EAP Sequences in EAP-FAST Phase 2
  91         * added support for EAP-TNC (Trusted Network Connect)
  92           (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST
  93           changes needed to run two methods in sequence (IF-T) and the IF-IMV
  94           and IF-TNCCS interfaces from TNCS)
  95         * added support for optional cryptobinding with PEAPv0
  96         * added fragmentation support for EAP-TNC
  97         * added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled)
  98           data
  99         * added support for opportunistic key caching (OKC)
 100
 101 2008-02-22 - v0.6.3
 102         * fixed Reassociation Response callback processing when using internal
 103           MLME (driver_{hostap,nl80211,test}.c)
 104         * updated FT support to use the latest draft, IEEE 802.11r/D9.0
 105         * copy optional Proxy-State attributes into RADIUS response when acting
 106           as a RADIUS authentication server
 107         * fixed EAPOL state machine to handle a case in which no response is
 108           received from the RADIUS authentication server; previous version
 109           could have triggered a crash in some cases after a timeout
 110         * fixed EAP-SIM/AKA realm processing to allow decorated usernames to
 111           be used
 112         * added a workaround for EAP-SIM/AKA peers that include incorrect null
 113           termination in the username
 114         * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER
 115           attribute in notification messages only when using fast
 116           reauthentication
 117         * fixed EAP-SIM Start response processing for fast reauthentication
 118           case
 119         * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST}
 120           phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method
 121
 122 2008-01-01 - v0.6.2
 123         * fixed EAP-SIM and EAP-AKA message parser to validate attribute
 124           lengths properly to avoid potential crash caused by invalid messages
 125         * added data structure for storing allocated buffers (struct wpabuf);
 126           this does not affect hostapd usage, but many of the APIs changed
 127           and various interfaces (e.g., EAP) is not compatible with old
 128           versions
 129         * added support for protecting EAP-AKA/Identity messages with
 130           AT_CHECKCODE (optional feature in RFC 4187)
 131         * added support for protected result indication with AT_RESULT_IND for
 132           EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1)
 133         * added support for configuring EAP-TTLS phase 2 non-EAP methods in
 134           EAP server configuration; previously all four were enabled for every
 135           phase 2 user, now all four are disabled by default and need to be
 136           enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP,
 137           TTLS-MSCHAPV2
 138         * removed old debug printing mechanism and the related 'debug'
 139           parameter in the configuration file; debug verbosity is now set with
 140           -d (or -dd) command line arguments
 141         * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
 142           only shared key/password authentication is supported in this version
 143
 144 2007-11-24 - v0.6.1
 145         * added experimental, integrated TLSv1 server implementation with the
 146           needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
 147           setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
 148           .config); this can be useful, e.g., if the target system does not
 149           have a suitable TLS library and a minimal code size is required
 150         * added support for EAP-FAST server method to the integrated EAP
 151           server
 152         * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
 153           draft (draft-ietf-emu-eap-gpsk-07.txt)
 154         * added a new configuration parameter, rsn_pairwise, to allow different
 155           pairwise cipher suites to be enabled for WPA and RSN/WPA2
 156           (note: if wpa_pairwise differs from rsn_pairwise, the driver will
 157           either need to support this or will have to use the WPA/RSN IEs from
 158           hostapd; currently, the included madwifi and bsd driver interfaces do
 159           not have support for this)
 160         * updated FT support to use the latest draft, IEEE 802.11r/D8.0
 161
 162 2007-05-28 - v0.6.0
 163         * added experimental IEEE 802.11r/D6.0 support
 164         * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
 165         * updated EAP-PSK to use the IANA-allocated EAP type 47
 166         * fixed EAP-PSK bit ordering of the Flags field
 167         * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
 168           by reading wpa_psk_file [Bug 181]
 169         * fixed EAP-TTLS AVP parser processing for too short AVP lengths
 170         * fixed IPv6 connection to RADIUS accounting server
 171         * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
 172           draft (draft-ietf-emu-eap-gpsk-04.txt)
 173         * hlr_auc_gw: read GSM triplet file into memory and rotate through the
 174           entries instead of only using the same three triplets every time
 175           (this does not work properly with tests using multiple clients, but
 176           provides bit better triplet data for testing a single client; anyway,
 177           if a better quality triplets are needed, GSM-Milenage should be used
 178           instead of hardcoded triplet file)
 179         * fixed EAP-MSCHAPv2 server to use a space between S and M parameters
 180           in Success Request [Bug 203]
 181         * added support for sending EAP-AKA Notifications in error cases
 182         * updated to use IEEE 802.11w/D2.0 for management frame protection
 183           (still experimental)
 184         * RADIUS server: added support for processing duplicate messages
 185           (retransmissions from RADIUS client) by replying with the previous
 186           reply
 187
 188 2006-11-24 - v0.5.6
 189         * added support for configuring and controlling multiple BSSes per
 190           radio interface (bss=<ifname> in hostapd.conf); this is only
 191           available with Devicescape and test driver interfaces
 192         * fixed PMKSA cache update in the end of successful RSN
 193           pre-authentication
 194         * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
 195           for each STA based on RADIUS Access-Accept attributes); this requires
 196           VLAN support from the kernel driver/802.11 stack and this is
 197           currently only available with Devicescape and test driver interfaces
 198         * driver_madwifi: fixed configuration of unencrypted modes (plaintext
 199           and IEEE 802.1X without WEP)
 200         * removed STAKey handshake since PeerKey handshake has replaced it in
 201           IEEE 802.11ma and there are no known deployments of STAKey
 202         * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
 203           draft (draft-ietf-emu-eap-gpsk-01.txt)
 204         * added preliminary implementation of IEEE 802.11w/D1.0 (management
 205           frame protection)
 206           (Note: this requires driver support to work properly.)
 207           (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
 208         * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
 209         * hlr_auc_gw: added support for reading per-IMSI Milenage keys and
 210           parameters from a text file to make it possible to implement proper
 211           GSM/UMTS authentication server for multiple SIM/USIM cards using
 212           EAP-SIM/EAP-AKA
 213         * fixed session timeout processing with drivers that do not use
 214           ieee802_11.c (e.g., madwifi)
 215
 216 2006-08-27 - v0.5.5
 217         * added 'hostapd_cli new_sta <addr>' command for adding a new STA into
 218           hostapd (e.g., to initialize wired network authentication based on an
 219           external signal)
 220         * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
 221           using WPA2 even if PMKSA caching is not used
 222         * added -P<pid file> argument for hostapd to write the current process
 223           id into a file
 224         * added support for RADIUS Authentication Server MIB (RFC 2619)
 225
 226 2006-06-20 - v0.5.4
 227         * fixed nt_password_hash build [Bug 144]
 228         * added PeerKey handshake implementation for IEEE 802.11e
 229           direct link setup (DLS) to replace STAKey handshake
 230         * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
 231           draft-clancy-emu-eap-shared-secret-00.txt)
 232         * fixed a segmentation fault when RSN pre-authentication was completed
 233           successfully [Bug 152]
 234
 235 2006-04-27 - v0.5.3
 236         * do not build nt_password_hash and hlr_auc_gw by default to avoid
 237           requiring a TLS library for a successful build; these programs can be
 238           build with 'make nt_password_hash' and 'make hlr_auc_gw'
 239         * added a new configuration option, eapol_version, that can be used to
 240           set EAPOL version to 1 (default is 2) to work around broken client
 241           implementations that drop EAPOL frames which use version number 2
 242           [Bug 89]
 243         * added support for EAP-SAKE (no EAP method number allocated yet, so
 244           this is using the same experimental type 255 as EAP-PSK)
 245         * fixed EAP-MSCHAPv2 message length validation
 246
 247 2006-03-19 - v0.5.2
 248         * fixed stdarg use in hostapd_logger(): if both stdout and syslog
 249           logging was enabled, hostapd could trigger a segmentation fault in
 250           vsyslog on some CPU -- C library combinations
 251         * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
 252           program to make it easier to use for implementing real SS7 gateway;
 253           eap_sim_db is not anymore used as a file name for GSM authentication
 254           triplets; instead, it is path to UNIX domain socket that will be used
 255           to communicate with the external gateway program (e.g., hlr_auc_gw)
 256         * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
 257           local information (GSM authentication triplets from a text file and
 258           hardcoded AKA authentication data); this can be used to test EAP-SIM
 259           and EAP-AKA
 260         * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
 261           to make it possible to test EAP-AKA with real USIM cards (this is
 262           disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
 263           to enable this)
 264         * driver_madwifi: added support for getting station RSN IE from
 265           madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
 266           broken with earlier change (r1357) in the driver
 267         * changed EAP method registration to use a dynamic list of methods
 268           instead of a static list generated at build time
 269         * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
 270           [Bug 125]
 271         * added ap_max_inactivity configuration parameter
 272
 273 2006-01-29 - v0.5.1
 274         * driver_test: added better support for multiple APs and STAs by using
 275           a directory with sockets that include MAC address for each device in
 276           the name (test_socket=DIR:/tmp/test)
 277         * added support for EAP expanded type (vendor specific EAP methods)
 278
 279 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
 280         * added experimental STAKey handshake implementation for IEEE 802.11e
 281           direct link setup (DLS); note: this is disabled by default in both
 282           build and runtime configuration (can be enabled with CONFIG_STAKEY=y
 283           and stakey=1)
 284         * added support for EAP methods to use callbacks to external programs
 285           by buffering a pending request and processing it after the EAP method
 286           is ready to continue
 287         * improved EAP-SIM database interface to allow external request to GSM
 288           HLR/AuC without blocking hostapd process
 289         * added support for using EAP-SIM pseudonyms and fast re-authentication
 290         * added support for EAP-AKA in the integrated EAP authenticator
 291         * added support for matching EAP identity prefixes (e.g., "1"*) in EAP
 292           user database to allow EAP-SIM/AKA selection without extra roundtrip
 293           for EAP-Nak negotiation
 294         * added support for storing EAP user password as NtPasswordHash instead
 295           of plaintext password when using MSCHAP or MSCHAPv2 for
 296           authentication (hash:<16-octet hex value>); added nt_password_hash
 297           tool for hashing password to generate NtPasswordHash

 299 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
 300         * driver_wired: fixed EAPOL sending to optionally use PAE group address
 301           as the destination instead of supplicant MAC address; this is
 302           disabled by default, but should be enabled with use_pae_group_addr=1
 303           in configuration file if the wired interface is used by only one
 304           device at the time (common switch configuration)
 305         * driver_madwifi: configure driver to use TKIP countermeasures in order
 306           to get correct behavior (IEEE 802.11 association failing; previously,
 307           association succeeded, but hostpad forced disassociation immediately)
 308         * driver_madwifi: added support for madwifi-ng
 309
 310 2005-10-27 - v0.4.6
 311         * added support for replacing user identity from EAP with RADIUS
 312           User-Name attribute from Access-Accept message, if that is included,
 313           for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
 314           tunneled identity into accounting messages when the RADIUS server
 315           does not support better way of doing this with Class attribute)
 316         * driver_madwifi: fixed EAPOL packet receive for configuration where
 317           ath# is part of a bridge interface
 318         * added a configuration file and log analyzer script for logwatch
 319         * fixed EAPOL state machine step function to process all state
 320           transitions before processing new events; this resolves a race
 321           condition in which EAPOL-Start message could trigger hostapd to send
 322           two EAP-Response/Identity frames to the authentication server
 323
 324 2005-09-25 - v0.4.5
 325         * added client CA list to the TLS certificate request in order to make
 326           it easier for the client to select which certificate to use
 327         * added experimental support for EAP-PSK
 328         * added support for WE-19 (hostap, madwifi)
 329
 330 2005-08-21 - v0.4.4
 331         * fixed build without CONFIG_RSN_PREAUTH
 332         * fixed FreeBSD build
 333
 334 2005-06-26 - v0.4.3
 335         * fixed PMKSA caching to copy User-Name and Class attributes so that
 336           RADIUS accounting gets correct information
 337         * start RADIUS accounting only after successful completion of WPA
 338           4-Way Handshake if WPA-PSK is used
 339         * fixed PMKSA caching for the case where STA (re)associates without
 340           first disassociating
 341
 342 2005-06-12 - v0.4.2
 343         * EAP-PAX is now registered as EAP type 46
 344         * fixed EAP-PAX MAC calculation
 345         * fixed EAP-PAX CK and ICK key derivation
 346         * renamed eap_authenticator configuration variable to eap_server to
 347           better match with RFC 3748 (EAP) terminology
 348         * driver_test: added support for testing hostapd with wpa_supplicant
 349           by using test driver interface without any kernel drivers or network
 350           cards
 351
 352 2005-05-22 - v0.4.1
 353         * fixed RADIUS server initialization when only auth or acct server
 354           is configured and the other one is left empty
 355         * driver_madwifi: added support for RADIUS accounting
 356         * driver_madwifi: added preliminary support for compiling against 'BSD'
 357           branch of madwifi CVS tree
 358         * driver_madwifi: fixed pairwise key removal to allow WPA reauth
 359           without disassociation
 360         * added support for reading additional certificates from PKCS#12 files
 361           and adding them to the certificate chain
 362         * fixed RADIUS Class attribute processing to only use Access-Accept
 363           packets to update Class; previously, other RADIUS authentication
 364           packets could have cleared Class attribute
 365         * added support for more than one Class attribute in RADIUS packets
 366         * added support for verifying certificate revocation list (CRL) when
 367           using integrated EAP authenticator for EAP-TLS; new hostapd.conf
 368           options 'check_crl'; CRL must be included in the ca_cert file for now
 369
 370 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
 371         * added support for including network information into
 372           EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
 373           (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
 374         * fixed a bug which caused some RSN pre-authentication cases to use
 375           freed memory and potentially crash hostapd
 376         * fixed private key loading for cases where passphrase is not set
 377         * added support for sending TLS alerts and aborting authentication
 378           when receiving a TLS alert
 379         * fixed WPA2 to add PMKSA cache entry when using integrated EAP
 380           authenticator
 381         * fixed PMKSA caching (EAP authentication was not skipped correctly
 382           with the new state machine changes from IEEE 802.1X draft)
 383         * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
 384           and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
 385           to be added to .config to include IPv6 support); for RADIUS server,
 386           radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
 387           in RADIUS clients file can then use IPv6 format
 388         * added experimental support for EAP-PAX
 389         * replaced hostapd control interface library (hostapd_ctrl.[ch]) with
 390           the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
 391
 392 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
 393
 394 2005-01-23 - v0.3.5
 395         * added support for configuring a forced PEAP version based on the
 396           Phase 1 identity
 397         * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
 398           to terminate authentication
 399         * fixed EAP identifier duplicate processing with the new IEEE 802.1X
 400           draft
 401         * clear accounting data in the driver when starting a new accounting
 402           session
 403         * driver_madwifi: filter wireless events based on ifindex to allow more
 404           than one network interface to be used
 405         * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
 406           setting if the packet does not pass MIC verification (e.g., due to
 407           incorrect PSK); previously, message 1/4 was not tried again if an
 408           invalid message 2/4 was received
 409         * fixed reconfiguration of RADIUS client retransmission timer when
 410           adding a new message to the pending list; previously, timer was not
 411           updated at this point and if there was a pending message with long
 412           time for the next retry, the new message needed to wait that long for
 413           its first retry, too
 414
 415 2005-01-09 - v0.3.4
 416         * added support for configuring multiple allowed EAP types for Phase 2
 417           authentication (EAP-PEAP, EAP-TTLS)
 418         * fixed EAPOL-Start processing to trigger WPA reauthentication
 419           (previously, only EAPOL authentication was done)
 420
 421 2005-01-02 - v0.3.3
 422         * added support for EAP-PEAP in the integrated EAP authenticator
 423         * added support for EAP-GTC in the integrated EAP authenticator
 424         * added support for configuring list of EAP methods for Phase 1 so that
 425           the integrated EAP authenticator can, e.g., use the wildcard entry
 426           for EAP-TLS and EAP-PEAP
 427         * added support for EAP-TTLS in the integrated EAP authenticator
 428         * added support for EAP-SIM in the integrated EAP authenticator
 429         * added support for using hostapd as a RADIUS authentication server
 430           with the integrated EAP authenticator taking care of EAP
 431           authentication (new hostapd.conf options: radius_server_clients and
 432           radius_server_auth_port); this is not included in default build; use
 433           CONFIG_RADIUS_SERVER=y in .config to include
 434
 435 2004-12-19 - v0.3.2
 436         * removed 'daemonize' configuration file option since it has not really
 437           been used at all for more than year
 438         * driver_madwifi: fixed group key setup and added get_ssid method
 439         * added support for EAP-MSCHAPv2 in the integrated EAP authenticator
 440
 441 2004-12-12 - v0.3.1
 442         * added support for integrated EAP-TLS authentication (new hostapd.conf
 443           variables: ca_cert, server_cert, private_key, private_key_passwd);
 444           this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
 445           external RADIUS server
 446         * added support for reading PKCS#12 (PFX) files (as a replacement for
 447           PEM/DER) to get certificate and private key (CONFIG_PKCS12)
 448
 449 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
 450         * added support for Acct-{Input,Output}-Gigawords
 451         * added support for Event-Timestamp (in RADIUS Accounting-Requests)
 452         * added support for RADIUS Authentication Client MIB (RFC2618)
 453         * added support for RADIUS Accounting Client MIB (RFC2620)
 454         * made EAP re-authentication period configurable (eap_reauth_period)
 455         * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
 456         * fixed EAPOL state machine to stop if STA is removed during
 457           eapol_sm_step(); this fixes at least one segfault triggering bug with
 458           IEEE 802.11i pre-authentication
 459         * added support for multiple WPA pre-shared keys (e.g., one for each
 460           client MAC address or keys shared by a group of clients);
 461           new hostapd.conf field wpa_psk_file for setting path to a text file
 462           containing PSKs, see hostapd.wpa_psk for an example
 463         * added support for multiple driver interfaces to allow hostapd to be
 464           used with other drivers
 465         * added wired authenticator driver interface (driver=wired in
 466           hostapd.conf, see wired.conf for example configuration)
 467         * added madwifi driver interface (driver=madwifi in hostapd.conf, see
 468           madwifi.conf for example configuration; Note: include files from
 469           madwifi project is needed for building and a configuration file,
 470           .config, needs to be created in hostapd directory with
 471           CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
 472           build)
 473         * fixed an alignment issue that could cause SHA-1 to fail on some
 474           platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
 475           align variables)
 476         * fixed RADIUS reconnection after an error in sending interim
 477           accounting packets
 478         * added hostapd control interface for external programs and an example
 479           CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
 480         * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
 481           'hostapd_cli sta <addr>')
 482         * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
 483         * added support for strict GTK rekeying (wpa_strict_rekey in
 484           hostapd.conf)
 485         * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
 486           (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
 487           IEEE 802.11F-2003)
 488         * added Prism54 driver interface (driver=prism54 in hostapd.conf;
 489           note: .config needs to be created in hostapd directory with
 490           CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
 491           build)
 492         * dual-licensed hostapd (GPLv2 and BSD licenses)
 493         * fixed RADIUS accounting to generate a new session id for cases where
 494           a station reassociates without first being complete deauthenticated
 495         * fixed STA disassociation handler to mark next timeout state to
 496           deauthenticate the station, i.e., skip long wait for inactivity poll
 497           and extra disassociation, if the STA disassociates without
 498           deauthenticating
 499         * added integrated EAP authenticator that can be used instead of
 500           external RADIUS authentication server; currently, only EAP-MD5 is
 501           supported, so this cannot yet be used for key distribution; the EAP
 502           method interface is generic, though, so adding new EAP methods should
 503           be straightforward; new hostapd.conf variables: 'eap_authenticator'
 504           and 'eap_user_file'; this obsoletes "minimal authentication server"
 505           ('minimal_eap' in hostapd.conf) which is now removed
 506         * added support for FreeBSD and driver interface for the BSD net80211
 507           layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
 508           .config); please note that some of the required kernel mods have not
 509           yet been committed
 510
 511 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
 512         * fixed some accounting cases where Accounting-Start was sent when
 513           IEEE 802.1X port was being deauthorized
 514
 515 2004-06-20 - v0.2.3
 516         * modified RADIUS client to re-connect the socket in case of certain
 517           error codes that are generated when a network interface state is
 518           changes (e.g., when IP address changes or the interface is set UP)
 519         * fixed couple of cases where EAPOL state for a station was freed
 520           twice causing a segfault for hostapd
 521         * fixed couple of bugs in processing WPA deauthentication (freed data
 522           was used)
 523
 524 2004-05-31 - v0.2.2
 525         * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
 526         * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
 527           cases where STAs dropped multicast frames as replay attacks
 528         * added support for copying RADIUS Attribute 'Class' from
 529           authentication messages into accounting messages
 530         * send canned EAP failure if RADIUS server sends Access-Reject without
 531           EAP message (previously, Supplicant was not notified in this case)
 532         * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
 533           not start EAPOL state machines if the STA selected to use WPA-PSK)
 534
 535 2004-05-06 - v0.2.1
 536         * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
 537           - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
 538             (i.e., IEEE 802.11i/D3.0)
 539           - supports WPA-only, RSN-only, and mixed WPA/RSN mode
 540           - both WPA-PSK and WPA-RADIUS/EAP are supported
 541           - PMKSA caching and pre-authentication
 542           - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
 543             wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
 544             rsn_preauth, rsn_preauth_interfaces
 545         * fixed interim accounting to remove any pending accounting messages
 546           to the STA before sending a new one
 547
 548 2004-02-15 - v0.2.0
 549         * added support for Acct-Interim-Interval:
 550           - draft-ietf-radius-acct-interim-01.txt
 551           - use Acct-Interim-Interval attribute from Access-Accept if local
 552             'radius_acct_interim_interval' is not set
 553           - allow different update intervals for each STA
 554         * fixed event loop to call signal handlers only after returning from
 555           the real signal handler
 556         * reset sta->timeout_next after successful association to make sure
 557           that the previously registered inactivity timer will not remove the
 558           STA immediately (e.g., if STA deauthenticates and re-associates
 559           before the timer is triggered).
 560         * added new hostapd.conf variable, nas_identifier, that can be used to
 561           add an optional RADIUS Attribute, NAS-Identifier, into authentication
 562           and accounting messages
 563         * added support for Accounting-On and Accounting-Off messages
 564         * fixed accounting session handling to send Accounting-Start only once
 565           per session and not to send Accounting-Stop if the session was not
 566           initialized properly
 567         * fixed Accounting-Stop statistics in cases where the message was
 568           previously sent after the kernel entry for the STA (and/or IEEE
 569           802.1X data) was removed
 570
 571
 572 Note:

 574 Older changes up to and including v0.1.0 are included in the ChangeLog
 575 of the Host AP driver.
