   1 ChangeLog for hostapd
   2
   3 ????-??-?? - v0.6.5
   4         * added support for SHA-256 as X.509 certificate digest when using the
   5           internal X.509/TLSv1 implementation
   6         * fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer
   7           identity lengths)
   8         * fixed internal TLSv1 implementation for abbreviated handshake (used
   9           by EAP-FAST server)
  10         * added support for setting VLAN ID for STAs based on local MAC ACL
  11           (accept_mac_file) as an alternative for RADIUS server-based
  12           configuration
  13         * updated management frame protection to use IEEE 802.11w/D6.0
  14           (adds a new association ping to protect against unauthenticated
  15           authenticate or (re)associate request frames dropping association)
  16         * added support for using SHA256-based stronger key derivation for WPA2
  17           (IEEE 802.11w)
  18         * added new "driver wrapper" for RADIUS-only configuration
  19           (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config)
  20         * fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2)
  21           is enabled in configuration
  22         * changed EAP-FAST configuration to use separate fields for A-ID and
  23           A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed
  24           16-octet len binary value for better interoperability with some peer
  25           implementations; eap_fast_a_id is now configured as a hex string
  26
  27 2008-08-10 - v0.6.4
  28         * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2
  29           Identity Request if identity is already known
  30         * added support for EAP Sequences in EAP-FAST Phase 2
  31         * added support for EAP-TNC (Trusted Network Connect)
  32           (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST
  33           changes needed to run two methods in sequence (IF-T) and the IF-IMV
  34           and IF-TNCCS interfaces from TNCS)
  35         * added support for optional cryptobinding with PEAPv0
  36         * added fragmentation support for EAP-TNC
  37         * added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled)
  38           data
  39         * added support for opportunistic key caching (OKC)
  40
  41 2008-02-22 - v0.6.3
  42         * fixed Reassociation Response callback processing when using internal
  43           MLME (driver_{hostap,nl80211,test}.c)
  44         * updated FT support to use the latest draft, IEEE 802.11r/D9.0
  45         * copy optional Proxy-State attributes into RADIUS response when acting
  46           as a RADIUS authentication server
  47         * fixed EAPOL state machine to handle a case in which no response is
  48           received from the RADIUS authentication server; previous version
  49           could have triggered a crash in some cases after a timeout
  50         * fixed EAP-SIM/AKA realm processing to allow decorated usernames to
  51           be used
  52         * added a workaround for EAP-SIM/AKA peers that include incorrect null
  53           termination in the username
  54         * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER
  55           attribute in notification messages only when using fast
  56           reauthentication
  57         * fixed EAP-SIM Start response processing for fast reauthentication
  58           case
  59         * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST}
  60           phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method
  61
  62 2008-01-01 - v0.6.2
  63         * fixed EAP-SIM and EAP-AKA message parser to validate attribute
  64           lengths properly to avoid potential crash caused by invalid messages
  65         * added data structure for storing allocated buffers (struct wpabuf);
  66           this does not affect hostapd usage, but many of the APIs changed
  67           and various interfaces (e.g., EAP) is not compatible with old
  68           versions
  69         * added support for protecting EAP-AKA/Identity messages with
  70           AT_CHECKCODE (optional feature in RFC 4187)
  71         * added support for protected result indication with AT_RESULT_IND for
  72           EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1)
  73         * added support for configuring EAP-TTLS phase 2 non-EAP methods in
  74           EAP server configuration; previously all four were enabled for every
  75           phase 2 user, now all four are disabled by default and need to be
  76           enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP,
  77           TTLS-MSCHAPV2
  78         * removed old debug printing mechanism and the related 'debug'
  79           parameter in the configuration file; debug verbosity is now set with
  80           -d (or -dd) command line arguments
  81         * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
  82           only shared key/password authentication is supported in this version
  83
  84 2007-11-24 - v0.6.1
  85         * added experimental, integrated TLSv1 server implementation with the
  86           needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
  87           setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
  88           .config); this can be useful, e.g., if the target system does not
  89           have a suitable TLS library and a minimal code size is required
  90         * added support for EAP-FAST server method to the integrated EAP
  91           server
  92         * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
  93           draft (draft-ietf-emu-eap-gpsk-07.txt)
  94         * added a new configuration parameter, rsn_pairwise, to allow different
  95           pairwise cipher suites to be enabled for WPA and RSN/WPA2
  96           (note: if wpa_pairwise differs from rsn_pairwise, the driver will
  97           either need to support this or will have to use the WPA/RSN IEs from
  98           hostapd; currently, the included madwifi and bsd driver interfaces do
  99           not have support for this)
 100         * updated FT support to use the latest draft, IEEE 802.11r/D8.0
 101
 102 2007-05-28 - v0.6.0
 103         * added experimental IEEE 802.11r/D6.0 support
 104         * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
 105         * updated EAP-PSK to use the IANA-allocated EAP type 47
 106         * fixed EAP-PSK bit ordering of the Flags field
 107         * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
 108           by reading wpa_psk_file [Bug 181]
 109         * fixed EAP-TTLS AVP parser processing for too short AVP lengths
 110         * fixed IPv6 connection to RADIUS accounting server
 111         * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
 112           draft (draft-ietf-emu-eap-gpsk-04.txt)
 113         * hlr_auc_gw: read GSM triplet file into memory and rotate through the
 114           entries instead of only using the same three triplets every time
 115           (this does not work properly with tests using multiple clients, but
 116           provides bit better triplet data for testing a single client; anyway,
 117           if a better quality triplets are needed, GSM-Milenage should be used
 118           instead of hardcoded triplet file)
 119         * fixed EAP-MSCHAPv2 server to use a space between S and M parameters
 120           in Success Request [Bug 203]
 121         * added support for sending EAP-AKA Notifications in error cases
 122         * updated to use IEEE 802.11w/D2.0 for management frame protection
 123           (still experimental)
 124         * RADIUS server: added support for processing duplicate messages
 125           (retransmissions from RADIUS client) by replying with the previous
 126           reply
 127
 128 2006-11-24 - v0.5.6
 129         * added support for configuring and controlling multiple BSSes per
 130           radio interface (bss=<ifname> in hostapd.conf); this is only
 131           available with Devicescape and test driver interfaces
 132         * fixed PMKSA cache update in the end of successful RSN
 133           pre-authentication
 134         * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
 135           for each STA based on RADIUS Access-Accept attributes); this requires
 136           VLAN support from the kernel driver/802.11 stack and this is
 137           currently only available with Devicescape and test driver interfaces
 138         * driver_madwifi: fixed configuration of unencrypted modes (plaintext
 139           and IEEE 802.1X without WEP)
 140         * removed STAKey handshake since PeerKey handshake has replaced it in
 141           IEEE 802.11ma and there are no known deployments of STAKey
 142         * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
 143           draft (draft-ietf-emu-eap-gpsk-01.txt)
 144         * added preliminary implementation of IEEE 802.11w/D1.0 (management
 145           frame protection)
 146           (Note: this requires driver support to work properly.)
 147           (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
 148         * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
 149         * hlr_auc_gw: added support for reading per-IMSI Milenage keys and
 150           parameters from a text file to make it possible to implement proper
 151           GSM/UMTS authentication server for multiple SIM/USIM cards using
 152           EAP-SIM/EAP-AKA
 153         * fixed session timeout processing with drivers that do not use
 154           ieee802_11.c (e.g., madwifi)
 155
 156 2006-08-27 - v0.5.5
 157         * added 'hostapd_cli new_sta <addr>' command for adding a new STA into
 158           hostapd (e.g., to initialize wired network authentication based on an
 159           external signal)
 160         * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
 161           using WPA2 even if PMKSA caching is not used
 162         * added -P<pid file> argument for hostapd to write the current process
 163           id into a file
 164         * added support for RADIUS Authentication Server MIB (RFC 2619)
 165
 166 2006-06-20 - v0.5.4
 167         * fixed nt_password_hash build [Bug 144]
 168         * added PeerKey handshake implementation for IEEE 802.11e
 169           direct link setup (DLS) to replace STAKey handshake
 170         * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
 171           draft-clancy-emu-eap-shared-secret-00.txt)
 172         * fixed a segmentation fault when RSN pre-authentication was completed
 173           successfully [Bug 152]
 174
 175 2006-04-27 - v0.5.3
 176         * do not build nt_password_hash and hlr_auc_gw by default to avoid
 177           requiring a TLS library for a successful build; these programs can be
 178           build with 'make nt_password_hash' and 'make hlr_auc_gw'
 179         * added a new configuration option, eapol_version, that can be used to
 180           set EAPOL version to 1 (default is 2) to work around broken client
 181           implementations that drop EAPOL frames which use version number 2
 182           [Bug 89]
 183         * added support for EAP-SAKE (no EAP method number allocated yet, so
 184           this is using the same experimental type 255 as EAP-PSK)
 185         * fixed EAP-MSCHAPv2 message length validation
 186
 187 2006-03-19 - v0.5.2
 188         * fixed stdarg use in hostapd_logger(): if both stdout and syslog
 189           logging was enabled, hostapd could trigger a segmentation fault in
 190           vsyslog on some CPU -- C library combinations
 191         * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
 192           program to make it easier to use for implementing real SS7 gateway;
 193           eap_sim_db is not anymore used as a file name for GSM authentication
 194           triplets; instead, it is path to UNIX domain socket that will be used
 195           to communicate with the external gateway program (e.g., hlr_auc_gw)
 196         * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
 197           local information (GSM authentication triplets from a text file and
 198           hardcoded AKA authentication data); this can be used to test EAP-SIM
 199           and EAP-AKA
 200         * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
 201           to make it possible to test EAP-AKA with real USIM cards (this is
 202           disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
 203           to enable this)
 204         * driver_madwifi: added support for getting station RSN IE from
 205           madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
 206           broken with earlier change (r1357) in the driver
 207         * changed EAP method registration to use a dynamic list of methods
 208           instead of a static list generated at build time
 209         * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
 210           [Bug 125]
 211         * added ap_max_inactivity configuration parameter
 212
 213 2006-01-29 - v0.5.1
 214         * driver_test: added better support for multiple APs and STAs by using
 215           a directory with sockets that include MAC address for each device in
 216           the name (test_socket=DIR:/tmp/test)
 217         * added support for EAP expanded type (vendor specific EAP methods)
 218
 219 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
 220         * added experimental STAKey handshake implementation for IEEE 802.11e
 221           direct link setup (DLS); note: this is disabled by default in both
 222           build and runtime configuration (can be enabled with CONFIG_STAKEY=y
 223           and stakey=1)
 224         * added support for EAP methods to use callbacks to external programs
 225           by buffering a pending request and processing it after the EAP method
 226           is ready to continue
 227         * improved EAP-SIM database interface to allow external request to GSM
 228           HLR/AuC without blocking hostapd process
 229         * added support for using EAP-SIM pseudonyms and fast re-authentication
 230         * added support for EAP-AKA in the integrated EAP authenticator
 231         * added support for matching EAP identity prefixes (e.g., "1"*) in EAP
 232           user database to allow EAP-SIM/AKA selection without extra roundtrip
 233           for EAP-Nak negotiation
 234         * added support for storing EAP user password as NtPasswordHash instead
 235           of plaintext password when using MSCHAP or MSCHAPv2 for
 236           authentication (hash:<16-octet hex value>); added nt_password_hash
 237           tool for hashing password to generate NtPasswordHash
 238
 239 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
 240         * driver_wired: fixed EAPOL sending to optionally use PAE group address
 241           as the destination instead of supplicant MAC address; this is
 242           disabled by default, but should be enabled with use_pae_group_addr=1
 243           in configuration file if the wired interface is used by only one
 244           device at the time (common switch configuration)
 245         * driver_madwifi: configure driver to use TKIP countermeasures in order
 246           to get correct behavior (IEEE 802.11 association failing; previously,
 247           association succeeded, but hostpad forced disassociation immediately)
 248         * driver_madwifi: added support for madwifi-ng
 249
 250 2005-10-27 - v0.4.6
 251         * added support for replacing user identity from EAP with RADIUS
 252           User-Name attribute from Access-Accept message, if that is included,
 253           for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
 254           tunneled identity into accounting messages when the RADIUS server
 255           does not support better way of doing this with Class attribute)
 256         * driver_madwifi: fixed EAPOL packet receive for configuration where
 257           ath# is part of a bridge interface
 258         * added a configuration file and log analyzer script for logwatch
 259         * fixed EAPOL state machine step function to process all state
 260           transitions before processing new events; this resolves a race
 261           condition in which EAPOL-Start message could trigger hostapd to send
 262           two EAP-Response/Identity frames to the authentication server
 263
 264 2005-09-25 - v0.4.5
 265         * added client CA list to the TLS certificate request in order to make
 266           it easier for the client to select which certificate to use
 267         * added experimental support for EAP-PSK
 268         * added support for WE-19 (hostap, madwifi)
 269
 270 2005-08-21 - v0.4.4
 271         * fixed build without CONFIG_RSN_PREAUTH
 272         * fixed FreeBSD build
 273
 274 2005-06-26 - v0.4.3
 275         * fixed PMKSA caching to copy User-Name and Class attributes so that
 276           RADIUS accounting gets correct information
 277         * start RADIUS accounting only after successful completion of WPA
 278           4-Way Handshake if WPA-PSK is used
 279         * fixed PMKSA caching for the case where STA (re)associates without
 280           first disassociating
 281
 282 2005-06-12 - v0.4.2
 283         * EAP-PAX is now registered as EAP type 46
 284         * fixed EAP-PAX MAC calculation
 285         * fixed EAP-PAX CK and ICK key derivation
 286         * renamed eap_authenticator configuration variable to eap_server to
 287           better match with RFC 3748 (EAP) terminology
 288         * driver_test: added support for testing hostapd with wpa_supplicant
 289           by using test driver interface without any kernel drivers or network
 290           cards
 291
 292 2005-05-22 - v0.4.1
 293         * fixed RADIUS server initialization when only auth or acct server
 294           is configured and the other one is left empty
 295         * driver_madwifi: added support for RADIUS accounting
 296         * driver_madwifi: added preliminary support for compiling against 'BSD'
 297           branch of madwifi CVS tree
 298         * driver_madwifi: fixed pairwise key removal to allow WPA reauth
 299           without disassociation
 300         * added support for reading additional certificates from PKCS#12 files
 301           and adding them to the certificate chain
 302         * fixed RADIUS Class attribute processing to only use Access-Accept
 303           packets to update Class; previously, other RADIUS authentication
 304           packets could have cleared Class attribute
 305         * added support for more than one Class attribute in RADIUS packets
 306         * added support for verifying certificate revocation list (CRL) when
 307           using integrated EAP authenticator for EAP-TLS; new hostapd.conf
 308           options 'check_crl'; CRL must be included in the ca_cert file for now
 309
 310 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
 311         * added support for including network information into
 312           EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
 313           (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
 314         * fixed a bug which caused some RSN pre-authentication cases to use
 315           freed memory and potentially crash hostapd
 316         * fixed private key loading for cases where passphrase is not set
 317         * added support for sending TLS alerts and aborting authentication
 318           when receiving a TLS alert
 319         * fixed WPA2 to add PMKSA cache entry when using integrated EAP
 320           authenticator
 321         * fixed PMKSA caching (EAP authentication was not skipped correctly
 322           with the new state machine changes from IEEE 802.1X draft)
 323         * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
 324           and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
 325           to be added to .config to include IPv6 support); for RADIUS server,
 326           radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
 327           in RADIUS clients file can then use IPv6 format
 328         * added experimental support for EAP-PAX
 329         * replaced hostapd control interface library (hostapd_ctrl.[ch]) with
 330           the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
 331
 332 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
 333
 334 2005-01-23 - v0.3.5
 335         * added support for configuring a forced PEAP version based on the
 336           Phase 1 identity
 337         * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
 338           to terminate authentication
 339         * fixed EAP identifier duplicate processing with the new IEEE 802.1X
 340           draft
 341         * clear accounting data in the driver when starting a new accounting
 342           session
 343         * driver_madwifi: filter wireless events based on ifindex to allow more
 344           than one network interface to be used
 345         * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
 346           setting if the packet does not pass MIC verification (e.g., due to
 347           incorrect PSK); previously, message 1/4 was not tried again if an
 348           invalid message 2/4 was received
 349         * fixed reconfiguration of RADIUS client retransmission timer when
 350           adding a new message to the pending list; previously, timer was not
 351           updated at this point and if there was a pending message with long
 352           time for the next retry, the new message needed to wait that long for
 353           its first retry, too
 354
 355 2005-01-09 - v0.3.4
 356         * added support for configuring multiple allowed EAP types for Phase 2
 357           authentication (EAP-PEAP, EAP-TTLS)
 358         * fixed EAPOL-Start processing to trigger WPA reauthentication
 359           (previously, only EAPOL authentication was done)
 360
 361 2005-01-02 - v0.3.3
 362         * added support for EAP-PEAP in the integrated EAP authenticator
 363         * added support for EAP-GTC in the integrated EAP authenticator
 364         * added support for configuring list of EAP methods for Phase 1 so that
 365           the integrated EAP authenticator can, e.g., use the wildcard entry
 366           for EAP-TLS and EAP-PEAP
 367         * added support for EAP-TTLS in the integrated EAP authenticator
 368         * added support for EAP-SIM in the integrated EAP authenticator
 369         * added support for using hostapd as a RADIUS authentication server
 370           with the integrated EAP authenticator taking care of EAP
 371           authentication (new hostapd.conf options: radius_server_clients and
 372           radius_server_auth_port); this is not included in default build; use
 373           CONFIG_RADIUS_SERVER=y in .config to include
 374
 375 2004-12-19 - v0.3.2
 376         * removed 'daemonize' configuration file option since it has not really
 377           been used at all for more than year
 378         * driver_madwifi: fixed group key setup and added get_ssid method
 379         * added support for EAP-MSCHAPv2 in the integrated EAP authenticator
 380
 381 2004-12-12 - v0.3.1
 382         * added support for integrated EAP-TLS authentication (new hostapd.conf
 383           variables: ca_cert, server_cert, private_key, private_key_passwd);
 384           this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
 385           external RADIUS server
 386         * added support for reading PKCS#12 (PFX) files (as a replacement for
 387           PEM/DER) to get certificate and private key (CONFIG_PKCS12)
 388
 389 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
 390         * added support for Acct-{Input,Output}-Gigawords
 391         * added support for Event-Timestamp (in RADIUS Accounting-Requests)
 392         * added support for RADIUS Authentication Client MIB (RFC2618)
 393         * added support for RADIUS Accounting Client MIB (RFC2620)
 394         * made EAP re-authentication period configurable (eap_reauth_period)
 395         * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
 396         * fixed EAPOL state machine to stop if STA is removed during
 397           eapol_sm_step(); this fixes at least one segfault triggering bug with
 398           IEEE 802.11i pre-authentication
 399         * added support for multiple WPA pre-shared keys (e.g., one for each
 400           client MAC address or keys shared by a group of clients);
 401           new hostapd.conf field wpa_psk_file for setting path to a text file
 402           containing PSKs, see hostapd.wpa_psk for an example
 403         * added support for multiple driver interfaces to allow hostapd to be
 404           used with other drivers
 405         * added wired authenticator driver interface (driver=wired in
 406           hostapd.conf, see wired.conf for example configuration)
 407         * added madwifi driver interface (driver=madwifi in hostapd.conf, see
 408           madwifi.conf for example configuration; Note: include files from
 409           madwifi project is needed for building and a configuration file,
 410           .config, needs to be created in hostapd directory with
 411           CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
 412           build)
 413         * fixed an alignment issue that could cause SHA-1 to fail on some
 414           platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
 415           align variables)
 416         * fixed RADIUS reconnection after an error in sending interim
 417           accounting packets
 418         * added hostapd control interface for external programs and an example
 419           CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
 420         * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
 421           'hostapd_cli sta <addr>')
 422         * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
 423         * added support for strict GTK rekeying (wpa_strict_rekey in
 424           hostapd.conf)
 425         * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
 426           (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
 427           IEEE 802.11F-2003)
 428         * added Prism54 driver interface (driver=prism54 in hostapd.conf;
 429           note: .config needs to be created in hostapd directory with
 430           CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
 431           build)
 432         * dual-licensed hostapd (GPLv2 and BSD licenses)
 433         * fixed RADIUS accounting to generate a new session id for cases where
 434           a station reassociates without first being complete deauthenticated
 435         * fixed STA disassociation handler to mark next timeout state to
 436           deauthenticate the station, i.e., skip long wait for inactivity poll
 437           and extra disassociation, if the STA disassociates without
 438           deauthenticating
 439         * added integrated EAP authenticator that can be used instead of
 440           external RADIUS authentication server; currently, only EAP-MD5 is
 441           supported, so this cannot yet be used for key distribution; the EAP
 442           method interface is generic, though, so adding new EAP methods should
 443           be straightforward; new hostapd.conf variables: 'eap_authenticator'
 444           and 'eap_user_file'; this obsoletes "minimal authentication server"
 445           ('minimal_eap' in hostapd.conf) which is now removed
 446         * added support for FreeBSD and driver interface for the BSD net80211
 447           layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
 448           .config); please note that some of the required kernel mods have not
 449           yet been committed
 450
 451 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
 452         * fixed some accounting cases where Accounting-Start was sent when
 453           IEEE 802.1X port was being deauthorized
 454
 455 2004-06-20 - v0.2.3
 456         * modified RADIUS client to re-connect the socket in case of certain
 457           error codes that are generated when a network interface state is
 458           changes (e.g., when IP address changes or the interface is set UP)
 459         * fixed couple of cases where EAPOL state for a station was freed
 460           twice causing a segfault for hostapd
 461         * fixed couple of bugs in processing WPA deauthentication (freed data
 462           was used)
 463
 464 2004-05-31 - v0.2.2
 465         * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
 466         * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
 467           cases where STAs dropped multicast frames as replay attacks
 468         * added support for copying RADIUS Attribute 'Class' from
 469           authentication messages into accounting messages
 470         * send canned EAP failure if RADIUS server sends Access-Reject without
 471           EAP message (previously, Supplicant was not notified in this case)
 472         * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
 473           not start EAPOL state machines if the STA selected to use WPA-PSK)
 474
 475 2004-05-06 - v0.2.1
 476         * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
 477           - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
 478             (i.e., IEEE 802.11i/D3.0)
 479           - supports WPA-only, RSN-only, and mixed WPA/RSN mode
 480           - both WPA-PSK and WPA-RADIUS/EAP are supported
 481           - PMKSA caching and pre-authentication
 482           - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
 483             wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
 484             rsn_preauth, rsn_preauth_interfaces
 485         * fixed interim accounting to remove any pending accounting messages
 486           to the STA before sending a new one
 487
 488 2004-02-15 - v0.2.0
 489         * added support for Acct-Interim-Interval:
 490           - draft-ietf-radius-acct-interim-01.txt
 491           - use Acct-Interim-Interval attribute from Access-Accept if local
 492             'radius_acct_interim_interval' is not set
 493           - allow different update intervals for each STA
 494         * fixed event loop to call signal handlers only after returning from
 495           the real signal handler
 496         * reset sta->timeout_next after successful association to make sure
 497           that the previously registered inactivity timer will not remove the
 498           STA immediately (e.g., if STA deauthenticates and re-associates
 499           before the timer is triggered).
 500         * added new hostapd.conf variable, nas_identifier, that can be used to
 501           add an optional RADIUS Attribute, NAS-Identifier, into authentication
 502           and accounting messages
 503         * added support for Accounting-On and Accounting-Off messages
 504         * fixed accounting session handling to send Accounting-Start only once
 505           per session and not to send Accounting-Stop if the session was not
 506           initialized properly
 507         * fixed Accounting-Stop statistics in cases where the message was
 508           previously sent after the kernel entry for the STA (and/or IEEE
 509           802.1X data) was removed
 510
