hostapd/ChangeLog

   1 ChangeLog for hostapd
   2
   3 2008-11-23 - v0.6.6
   4         * added a new configuration option, wpa_ptk_rekey, that can be used to
   5           enforce frequent PTK rekeying, e.g., to mitigate some attacks against
   6           TKIP deficiencies
   7         * updated OpenSSL code for EAP-FAST to use an updated version of the
   8           session ticket overriding API that was included into the upstream
   9           OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
  10           needed with that version anymore)
  11         * changed channel flags configuration to read the information from
  12           the driver (e.g., via driver_nl80211 when using mac80211) instead of
  13           using hostapd as the source of the regulatory information (i.e.,
  14           information from CRDA is now used with mac80211); this allows 5 GHz
  15           channels to be used with hostapd (if allowed in the current
  16           regulatory domain)
  17         * fixed EAP-TLS message processing for the last TLS message if it is
  18           large enough to require fragmentation (e.g., if a large Session
  19           Ticket data is included)
  20         * fixed listen interval configuration for nl80211 drivers
  21
  22 2008-11-01 - v0.6.5
  23         * added support for SHA-256 as X.509 certificate digest when using the
  24           internal X.509/TLSv1 implementation
  25         * fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer
  26           identity lengths)
  27         * fixed internal TLSv1 implementation for abbreviated handshake (used
  28           by EAP-FAST server)
  29         * added support for setting VLAN ID for STAs based on local MAC ACL
  30           (accept_mac_file) as an alternative for RADIUS server-based
  31           configuration
  32         * updated management frame protection to use IEEE 802.11w/D6.0
  33           (adds a new association ping to protect against unauthenticated
  34           authenticate or (re)associate request frames dropping association)
  35         * added support for using SHA256-based stronger key derivation for WPA2
  36           (IEEE 802.11w)
  37         * added new "driver wrapper" for RADIUS-only configuration
  38           (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config)
  39         * fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2)
  40           is enabled in configuration
  41         * changed EAP-FAST configuration to use separate fields for A-ID and
  42           A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed
  43           16-octet len binary value for better interoperability with some peer
  44           implementations; eap_fast_a_id is now configured as a hex string
  45         * driver_nl80211: Updated to match the current Linux mac80211 AP mode
  46           configuration (wireless-testing.git and Linux kernel releases
  47           starting from 2.6.29)
  48
  49 2008-08-10 - v0.6.4
  50         * added peer identity into EAP-FAST PAC-Opaque and skip Phase 2
  51           Identity Request if identity is already known
  52         * added support for EAP Sequences in EAP-FAST Phase 2
  53         * added support for EAP-TNC (Trusted Network Connect)
  54           (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST
  55           changes needed to run two methods in sequence (IF-T) and the IF-IMV
  56           and IF-TNCCS interfaces from TNCS)
  57         * added support for optional cryptobinding with PEAPv0
  58         * added fragmentation support for EAP-TNC
  59         * added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled)
  60           data
  61         * added support for opportunistic key caching (OKC)
  62
  63 2008-02-22 - v0.6.3
  64         * fixed Reassociation Response callback processing when using internal
  65           MLME (driver_{hostap,nl80211,test}.c)
  66         * updated FT support to use the latest draft, IEEE 802.11r/D9.0
  67         * copy optional Proxy-State attributes into RADIUS response when acting
  68           as a RADIUS authentication server
  69         * fixed EAPOL state machine to handle a case in which no response is
  70           received from the RADIUS authentication server; previous version
  71           could have triggered a crash in some cases after a timeout
  72         * fixed EAP-SIM/AKA realm processing to allow decorated usernames to
  73           be used
  74         * added a workaround for EAP-SIM/AKA peers that include incorrect null
  75           termination in the username
  76         * fixed EAP-SIM/AKA protected result indication to include AT_COUNTER
  77           attribute in notification messages only when using fast
  78           reauthentication
  79         * fixed EAP-SIM Start response processing for fast reauthentication
  80           case
  81         * added support for pending EAP processing in EAP-{PEAP,TTLS,FAST}
  82           phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method
  83
  84 2008-01-01 - v0.6.2
  85         * fixed EAP-SIM and EAP-AKA message parser to validate attribute
  86           lengths properly to avoid potential crash caused by invalid messages
  87         * added data structure for storing allocated buffers (struct wpabuf);
  88           this does not affect hostapd usage, but many of the APIs changed
  89           and various interfaces (e.g., EAP) is not compatible with old
  90           versions
  91         * added support for protecting EAP-AKA/Identity messages with
  92           AT_CHECKCODE (optional feature in RFC 4187)
  93         * added support for protected result indication with AT_RESULT_IND for
  94           EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1)
  95         * added support for configuring EAP-TTLS phase 2 non-EAP methods in
  96           EAP server configuration; previously all four were enabled for every
  97           phase 2 user, now all four are disabled by default and need to be
  98           enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP,
  99           TTLS-MSCHAPV2
 100         * removed old debug printing mechanism and the related 'debug'
 101           parameter in the configuration file; debug verbosity is now set with
 102           -d (or -dd) command line arguments
 103         * added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
 104           only shared key/password authentication is supported in this version
 105
 106 2007-11-24 - v0.6.1
 107         * added experimental, integrated TLSv1 server implementation with the
 108           needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
 109           setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
 110           .config); this can be useful, e.g., if the target system does not
 111           have a suitable TLS library and a minimal code size is required
 112         * added support for EAP-FAST server method to the integrated EAP
 113           server
 114         * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
 115           draft (draft-ietf-emu-eap-gpsk-07.txt)
 116         * added a new configuration parameter, rsn_pairwise, to allow different
 117           pairwise cipher suites to be enabled for WPA and RSN/WPA2
 118           (note: if wpa_pairwise differs from rsn_pairwise, the driver will
 119           either need to support this or will have to use the WPA/RSN IEs from
 120           hostapd; currently, the included madwifi and bsd driver interfaces do
 121           not have support for this)
 122         * updated FT support to use the latest draft, IEEE 802.11r/D8.0
 123
 124 2007-05-28 - v0.6.0
 125         * added experimental IEEE 802.11r/D6.0 support
 126         * updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
 127         * updated EAP-PSK to use the IANA-allocated EAP type 47
 128         * fixed EAP-PSK bit ordering of the Flags field
 129         * fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
 130           by reading wpa_psk_file [Bug 181]
 131         * fixed EAP-TTLS AVP parser processing for too short AVP lengths
 132         * fixed IPv6 connection to RADIUS accounting server
 133         * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
 134           draft (draft-ietf-emu-eap-gpsk-04.txt)
 135         * hlr_auc_gw: read GSM triplet file into memory and rotate through the
 136           entries instead of only using the same three triplets every time
 137           (this does not work properly with tests using multiple clients, but
 138           provides bit better triplet data for testing a single client; anyway,
 139           if a better quality triplets are needed, GSM-Milenage should be used
 140           instead of hardcoded triplet file)
 141         * fixed EAP-MSCHAPv2 server to use a space between S and M parameters
 142           in Success Request [Bug 203]
 143         * added support for sending EAP-AKA Notifications in error cases
 144         * updated to use IEEE 802.11w/D2.0 for management frame protection
 145           (still experimental)
 146         * RADIUS server: added support for processing duplicate messages
 147           (retransmissions from RADIUS client) by replying with the previous
 148           reply
 149
 150 2006-11-24 - v0.5.6
 151         * added support for configuring and controlling multiple BSSes per
 152           radio interface (bss=<ifname> in hostapd.conf); this is only
 153           available with Devicescape and test driver interfaces
 154         * fixed PMKSA cache update in the end of successful RSN
 155           pre-authentication
 156         * added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
 157           for each STA based on RADIUS Access-Accept attributes); this requires
 158           VLAN support from the kernel driver/802.11 stack and this is
 159           currently only available with Devicescape and test driver interfaces
 160         * driver_madwifi: fixed configuration of unencrypted modes (plaintext
 161           and IEEE 802.1X without WEP)
 162         * removed STAKey handshake since PeerKey handshake has replaced it in
 163           IEEE 802.11ma and there are no known deployments of STAKey
 164         * updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
 165           draft (draft-ietf-emu-eap-gpsk-01.txt)
 166         * added preliminary implementation of IEEE 802.11w/D1.0 (management
 167           frame protection)
 168           (Note: this requires driver support to work properly.)
 169           (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
 170         * hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
 171         * hlr_auc_gw: added support for reading per-IMSI Milenage keys and
 172           parameters from a text file to make it possible to implement proper
 173           GSM/UMTS authentication server for multiple SIM/USIM cards using
 174           EAP-SIM/EAP-AKA
 175         * fixed session timeout processing with drivers that do not use
 176           ieee802_11.c (e.g., madwifi)
 177
 178 2006-08-27 - v0.5.5
 179         * added 'hostapd_cli new_sta <addr>' command for adding a new STA into
 180           hostapd (e.g., to initialize wired network authentication based on an
 181           external signal)
 182         * fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
 183           using WPA2 even if PMKSA caching is not used
 184         * added -P<pid file> argument for hostapd to write the current process
 185           id into a file
 186         * added support for RADIUS Authentication Server MIB (RFC 2619)
 187
 188 2006-06-20 - v0.5.4
 189         * fixed nt_password_hash build [Bug 144]
 190         * added PeerKey handshake implementation for IEEE 802.11e
 191           direct link setup (DLS) to replace STAKey handshake
 192         * added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
 193           draft-clancy-emu-eap-shared-secret-00.txt)
 194         * fixed a segmentation fault when RSN pre-authentication was completed
 195           successfully [Bug 152]
 196
 197 2006-04-27 - v0.5.3
 198         * do not build nt_password_hash and hlr_auc_gw by default to avoid
 199           requiring a TLS library for a successful build; these programs can be
 200           build with 'make nt_password_hash' and 'make hlr_auc_gw'
 201         * added a new configuration option, eapol_version, that can be used to
 202           set EAPOL version to 1 (default is 2) to work around broken client
 203           implementations that drop EAPOL frames which use version number 2
 204           [Bug 89]
 205         * added support for EAP-SAKE (no EAP method number allocated yet, so
 206           this is using the same experimental type 255 as EAP-PSK)
 207         * fixed EAP-MSCHAPv2 message length validation
 208
 209 2006-03-19 - v0.5.2
 210         * fixed stdarg use in hostapd_logger(): if both stdout and syslog
 211           logging was enabled, hostapd could trigger a segmentation fault in
 212           vsyslog on some CPU -- C library combinations
 213         * moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
 214           program to make it easier to use for implementing real SS7 gateway;
 215           eap_sim_db is not anymore used as a file name for GSM authentication
 216           triplets; instead, it is path to UNIX domain socket that will be used
 217           to communicate with the external gateway program (e.g., hlr_auc_gw)
 218         * added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
 219           local information (GSM authentication triplets from a text file and
 220           hardcoded AKA authentication data); this can be used to test EAP-SIM
 221           and EAP-AKA
 222         * added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
 223           to make it possible to test EAP-AKA with real USIM cards (this is
 224           disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
 225           to enable this)
 226         * driver_madwifi: added support for getting station RSN IE from
 227           madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
 228           broken with earlier change (r1357) in the driver
 229         * changed EAP method registration to use a dynamic list of methods
 230           instead of a static list generated at build time
 231         * fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
 232           [Bug 125]
 233         * added ap_max_inactivity configuration parameter
 234
 235 2006-01-29 - v0.5.1
 236         * driver_test: added better support for multiple APs and STAs by using
 237           a directory with sockets that include MAC address for each device in
 238           the name (test_socket=DIR:/tmp/test)
 239         * added support for EAP expanded type (vendor specific EAP methods)
 240
 241 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
 242         * added experimental STAKey handshake implementation for IEEE 802.11e
 243           direct link setup (DLS); note: this is disabled by default in both
 244           build and runtime configuration (can be enabled with CONFIG_STAKEY=y
 245           and stakey=1)
 246         * added support for EAP methods to use callbacks to external programs
 247           by buffering a pending request and processing it after the EAP method
 248           is ready to continue
 249         * improved EAP-SIM database interface to allow external request to GSM
 250           HLR/AuC without blocking hostapd process
 251         * added support for using EAP-SIM pseudonyms and fast re-authentication
 252         * added support for EAP-AKA in the integrated EAP authenticator
 253         * added support for matching EAP identity prefixes (e.g., "1"*) in EAP
 254           user database to allow EAP-SIM/AKA selection without extra roundtrip
 255           for EAP-Nak negotiation
 256         * added support for storing EAP user password as NtPasswordHash instead
 257           of plaintext password when using MSCHAP or MSCHAPv2 for
 258           authentication (hash:<16-octet hex value>); added nt_password_hash
 259           tool for hashing password to generate NtPasswordHash
 260
 261 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
 262         * driver_wired: fixed EAPOL sending to optionally use PAE group address
 263           as the destination instead of supplicant MAC address; this is
 264           disabled by default, but should be enabled with use_pae_group_addr=1
 265           in configuration file if the wired interface is used by only one
 266           device at the time (common switch configuration)
 267         * driver_madwifi: configure driver to use TKIP countermeasures in order
 268           to get correct behavior (IEEE 802.11 association failing; previously,
 269           association succeeded, but hostpad forced disassociation immediately)
 270         * driver_madwifi: added support for madwifi-ng
 271
 272 2005-10-27 - v0.4.6
 273         * added support for replacing user identity from EAP with RADIUS
 274           User-Name attribute from Access-Accept message, if that is included,
 275           for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
 276           tunneled identity into accounting messages when the RADIUS server
 277           does not support better way of doing this with Class attribute)
 278         * driver_madwifi: fixed EAPOL packet receive for configuration where
 279           ath# is part of a bridge interface
 280         * added a configuration file and log analyzer script for logwatch
 281         * fixed EAPOL state machine step function to process all state
 282           transitions before processing new events; this resolves a race
 283           condition in which EAPOL-Start message could trigger hostapd to send
 284           two EAP-Response/Identity frames to the authentication server
 285
 286 2005-09-25 - v0.4.5
 287         * added client CA list to the TLS certificate request in order to make
 288           it easier for the client to select which certificate to use
 289         * added experimental support for EAP-PSK
 290         * added support for WE-19 (hostap, madwifi)
 291
 292 2005-08-21 - v0.4.4
 293         * fixed build without CONFIG_RSN_PREAUTH
 294         * fixed FreeBSD build
 295
 296 2005-06-26 - v0.4.3
 297         * fixed PMKSA caching to copy User-Name and Class attributes so that
 298           RADIUS accounting gets correct information
 299         * start RADIUS accounting only after successful completion of WPA
 300           4-Way Handshake if WPA-PSK is used
 301         * fixed PMKSA caching for the case where STA (re)associates without
 302           first disassociating

 304 2005-06-12 - v0.4.2
 305         * EAP-PAX is now registered as EAP type 46
 306         * fixed EAP-PAX MAC calculation
 307         * fixed EAP-PAX CK and ICK key derivation
 308         * renamed eap_authenticator configuration variable to eap_server to
 309           better match with RFC 3748 (EAP) terminology
 310         * driver_test: added support for testing hostapd with wpa_supplicant
 311           by using test driver interface without any kernel drivers or network
 312           cards
 313
 314 2005-05-22 - v0.4.1
 315         * fixed RADIUS server initialization when only auth or acct server
 316           is configured and the other one is left empty
 317         * driver_madwifi: added support for RADIUS accounting
 318         * driver_madwifi: added preliminary support for compiling against 'BSD'
 319           branch of madwifi CVS tree
 320         * driver_madwifi: fixed pairwise key removal to allow WPA reauth
 321           without disassociation
 322         * added support for reading additional certificates from PKCS#12 files
 323           and adding them to the certificate chain
 324         * fixed RADIUS Class attribute processing to only use Access-Accept
 325           packets to update Class; previously, other RADIUS authentication
 326           packets could have cleared Class attribute
 327         * added support for more than one Class attribute in RADIUS packets
 328         * added support for verifying certificate revocation list (CRL) when
 329           using integrated EAP authenticator for EAP-TLS; new hostapd.conf
 330           options 'check_crl'; CRL must be included in the ca_cert file for now
 331
 332 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
 333         * added support for including network information into
 334           EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
 335           (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
 336         * fixed a bug which caused some RSN pre-authentication cases to use
 337           freed memory and potentially crash hostapd
 338         * fixed private key loading for cases where passphrase is not set
 339         * added support for sending TLS alerts and aborting authentication
 340           when receiving a TLS alert
 341         * fixed WPA2 to add PMKSA cache entry when using integrated EAP
 342           authenticator
 343         * fixed PMKSA caching (EAP authentication was not skipped correctly
 344           with the new state machine changes from IEEE 802.1X draft)
 345         * added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
 346           and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
 347           to be added to .config to include IPv6 support); for RADIUS server,
 348           radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
 349           in RADIUS clients file can then use IPv6 format
 350         * added experimental support for EAP-PAX
 351         * replaced hostapd control interface library (hostapd_ctrl.[ch]) with
 352           the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
 353
 354 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
 355
 356 2005-01-23 - v0.3.5
 357         * added support for configuring a forced PEAP version based on the
 358           Phase 1 identity
 359         * fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
 360           to terminate authentication
 361         * fixed EAP identifier duplicate processing with the new IEEE 802.1X
 362           draft
 363         * clear accounting data in the driver when starting a new accounting
 364           session
 365         * driver_madwifi: filter wireless events based on ifindex to allow more
 366           than one network interface to be used
 367         * fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
 368           setting if the packet does not pass MIC verification (e.g., due to
 369           incorrect PSK); previously, message 1/4 was not tried again if an
 370           invalid message 2/4 was received
 371         * fixed reconfiguration of RADIUS client retransmission timer when
 372           adding a new message to the pending list; previously, timer was not
 373           updated at this point and if there was a pending message with long
 374           time for the next retry, the new message needed to wait that long for
 375           its first retry, too
 376
 377 2005-01-09 - v0.3.4
 378         * added support for configuring multiple allowed EAP types for Phase 2
 379           authentication (EAP-PEAP, EAP-TTLS)
 380         * fixed EAPOL-Start processing to trigger WPA reauthentication
 381           (previously, only EAPOL authentication was done)
 382
 383 2005-01-02 - v0.3.3
 384         * added support for EAP-PEAP in the integrated EAP authenticator
 385         * added support for EAP-GTC in the integrated EAP authenticator
 386         * added support for configuring list of EAP methods for Phase 1 so that
 387           the integrated EAP authenticator can, e.g., use the wildcard entry
 388           for EAP-TLS and EAP-PEAP
 389         * added support for EAP-TTLS in the integrated EAP authenticator
 390         * added support for EAP-SIM in the integrated EAP authenticator
 391         * added support for using hostapd as a RADIUS authentication server
 392           with the integrated EAP authenticator taking care of EAP
 393           authentication (new hostapd.conf options: radius_server_clients and
 394           radius_server_auth_port); this is not included in default build; use
 395           CONFIG_RADIUS_SERVER=y in .config to include
 396
 397 2004-12-19 - v0.3.2
 398         * removed 'daemonize' configuration file option since it has not really
 399           been used at all for more than year
 400         * driver_madwifi: fixed group key setup and added get_ssid method
 401         * added support for EAP-MSCHAPv2 in the integrated EAP authenticator
 402
 403 2004-12-12 - v0.3.1
 404         * added support for integrated EAP-TLS authentication (new hostapd.conf
 405           variables: ca_cert, server_cert, private_key, private_key_passwd);
 406           this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
 407           external RADIUS server
 408         * added support for reading PKCS#12 (PFX) files (as a replacement for
 409           PEM/DER) to get certificate and private key (CONFIG_PKCS12)
 410
 411 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
 412         * added support for Acct-{Input,Output}-Gigawords
 413         * added support for Event-Timestamp (in RADIUS Accounting-Requests)
 414         * added support for RADIUS Authentication Client MIB (RFC2618)
 415         * added support for RADIUS Accounting Client MIB (RFC2620)
 416         * made EAP re-authentication period configurable (eap_reauth_period)
 417         * fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
 418         * fixed EAPOL state machine to stop if STA is removed during
 419           eapol_sm_step(); this fixes at least one segfault triggering bug with
 420           IEEE 802.11i pre-authentication
 421         * added support for multiple WPA pre-shared keys (e.g., one for each
 422           client MAC address or keys shared by a group of clients);
 423           new hostapd.conf field wpa_psk_file for setting path to a text file
 424           containing PSKs, see hostapd.wpa_psk for an example
 425         * added support for multiple driver interfaces to allow hostapd to be
 426           used with other drivers
 427         * added wired authenticator driver interface (driver=wired in
 428           hostapd.conf, see wired.conf for example configuration)
 429         * added madwifi driver interface (driver=madwifi in hostapd.conf, see
 430           madwifi.conf for example configuration; Note: include files from
 431           madwifi project is needed for building and a configuration file,
 432           .config, needs to be created in hostapd directory with
 433           CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
 434           build)
 435         * fixed an alignment issue that could cause SHA-1 to fail on some
 436           platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
 437           align variables)
 438         * fixed RADIUS reconnection after an error in sending interim
 439           accounting packets
 440         * added hostapd control interface for external programs and an example
 441           CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
 442         * started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
 443           'hostapd_cli sta <addr>')
 444         * finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
 445         * added support for strict GTK rekeying (wpa_strict_rekey in
 446           hostapd.conf)
 447         * updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
 448           (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
 449           IEEE 802.11F-2003)
 450         * added Prism54 driver interface (driver=prism54 in hostapd.conf;
 451           note: .config needs to be created in hostapd directory with
 452           CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
 453           build)
 454         * dual-licensed hostapd (GPLv2 and BSD licenses)
 455         * fixed RADIUS accounting to generate a new session id for cases where
 456           a station reassociates without first being complete deauthenticated
 457         * fixed STA disassociation handler to mark next timeout state to
 458           deauthenticate the station, i.e., skip long wait for inactivity poll
 459           and extra disassociation, if the STA disassociates without
 460           deauthenticating
 461         * added integrated EAP authenticator that can be used instead of
 462           external RADIUS authentication server; currently, only EAP-MD5 is
 463           supported, so this cannot yet be used for key distribution; the EAP
 464           method interface is generic, though, so adding new EAP methods should
 465           be straightforward; new hostapd.conf variables: 'eap_authenticator'
 466           and 'eap_user_file'; this obsoletes "minimal authentication server"
 467           ('minimal_eap' in hostapd.conf) which is now removed
 468         * added support for FreeBSD and driver interface for the BSD net80211
 469           layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
 470           .config); please note that some of the required kernel mods have not
 471           yet been committed
 472
 473 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
 474         * fixed some accounting cases where Accounting-Start was sent when
 475           IEEE 802.1X port was being deauthorized
 476
 477 2004-06-20 - v0.2.3
 478         * modified RADIUS client to re-connect the socket in case of certain
 479           error codes that are generated when a network interface state is
 480           changes (e.g., when IP address changes or the interface is set UP)
 481         * fixed couple of cases where EAPOL state for a station was freed
 482           twice causing a segfault for hostapd
 483         * fixed couple of bugs in processing WPA deauthentication (freed data
 484           was used)
 485
 486 2004-05-31 - v0.2.2
 487         * fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
 488         * fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
 489           cases where STAs dropped multicast frames as replay attacks
 490         * added support for copying RADIUS Attribute 'Class' from
 491           authentication messages into accounting messages
 492         * send canned EAP failure if RADIUS server sends Access-Reject without
 493           EAP message (previously, Supplicant was not notified in this case)
 494         * fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
 495           not start EAPOL state machines if the STA selected to use WPA-PSK)
 496
 497 2004-05-06 - v0.2.1
 498         * added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
 499           - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
 500             (i.e., IEEE 802.11i/D3.0)
 501           - supports WPA-only, RSN-only, and mixed WPA/RSN mode
 502           - both WPA-PSK and WPA-RADIUS/EAP are supported
 503           - PMKSA caching and pre-authentication
 504           - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
 505             wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
 506             rsn_preauth, rsn_preauth_interfaces
 507         * fixed interim accounting to remove any pending accounting messages
 508           to the STA before sending a new one
 509
 510 2004-02-15 - v0.2.0
 511         * added support for Acct-Interim-Interval:
 512           - draft-ietf-radius-acct-interim-01.txt
 513           - use Acct-Interim-Interval attribute from Access-Accept if local
 514             'radius_acct_interim_interval' is not set
 515           - allow different update intervals for each STA
 516         * fixed event loop to call signal handlers only after returning from
 517           the real signal handler
 518         * reset sta->timeout_next after successful association to make sure
 519           that the previously registered inactivity timer will not remove the
 520           STA immediately (e.g., if STA deauthenticates and re-associates
 521           before the timer is triggered).
 522         * added new hostapd.conf variable, nas_identifier, that can be used to
 523           add an optional RADIUS Attribute, NAS-Identifier, into authentication
 524           and accounting messages
 525         * added support for Accounting-On and Accounting-Off messages
 526         * fixed accounting session handling to send Accounting-Start only once
 527           per session and not to send Accounting-Stop if the session was not
 528           initialized properly
 529         * fixed Accounting-Stop statistics in cases where the message was
 530           previously sent after the kernel entry for the STA (and/or IEEE
 531           802.1X data) was removed
 532
 533
 534 Note:
 535
 536 Older changes up to and including v0.1.0 are included in the ChangeLog
 537 of the Host AP driver.
