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