      1 ChangeLog for wpa_supplicant
      2 
      3 2008-11-28 - v0.5.11
      4 	* fixed race condition between disassociation event and group key
      5 	  handshake to avoid getting stuck in incorrect state [Bug 261]
      6 	* updated D-Bus usage to avoid deprecated functions
      7 	* silence SIOCSIWAUTH ioctl failure message (these can be ignored in
      8 	  most cases and are now only shown in debug output)
      9 	* increase timeout for IBSS connection
     10 	* driver_wext: do not overwrite BSS frequency if channel was already
     11 	  received
     12 	* driver_wext: set interface down for mode switches, if needed (e.g.,
     13 	  for mac80211)
     14 	* driver_wext: fixed re-initialization of a removed and re-inserted
     15 	  interface (e.g., USB dongle or on resume if driver was unloaded for
     16 	  suspend)
     17 	* improve per-SSID scanning for drivers that report background scan
     18 	  results frequently
     19 	* fixed scanning behavior after a failed initial association
     20 	* driver_wext: fixed processing of invalid event messages from kernel
     21 	  not to crash wpa_supplicant (this could happen when using 64-bit
     22 	  kernel with 32-bit userspace)
     23 	* fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
     24 	  not bytes
     25 	* fixed canceling of PMKSA caching when using drivers that generate
     26 	  RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
     27 	  about
     28 
     29 2008-02-19 - v0.5.10
     30 	* added support for Makefile builds to include debug-log-to-a-file
     31 	  functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
     32 	* added network configuration parameter 'frequency' for setting
     33 	  initial channel for IBSS (adhoc) networks
     34 	* fixed EAP-SIM and EAP-AKA message parser to validate attribute
     35 	  lengths properly to avoid potential crash caused by invalid messages
     36 	* added driver_wext workaround for race condition between scanning and
     37 	  association with drivers that take very long time to scan all
     38 	  channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
     39 	  using a longer hardcoded timeout for the scan if the driver supports
     40 	  notifications for scan completion (SIOCGIWSCAN event); this helps,
     41 	  e.g., in cases where wpa_supplicant and madwifi driver ended up in
     42 	  loop where the driver did not even try to associate
     43 	* fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
     44 	  attributes in EAP-SIM Start/Response when using fast reauthentication
     45 	* fixed problems in getting NDIS events from WMI on Windows 2000
     46 
     47 2007-12-02 - v0.5.9
     48 	* fixed an integer overflow issue in the ASN.1 parser used by the
     49 	  (experimental) internal TLS implementation to avoid a potential
     50 	  buffer read overflow
     51 	* fixed a race condition with -W option (wait for a control interface
     52 	  monitor before starting) that could have caused the first messages to
     53 	  be lost
     54 	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
     55 	  draft (draft-ietf-emu-eap-gpsk-07.txt)
     56 	* added ctrl_iface RECONNECT (wpa_cli reconnect) command
     57 	  (like reassociate, but only takes effect if already associated)
     58 	* fixed a possible race condition between wpa_cli reassociate and
     59 	  wpa_cli disconnect
     60 	* return a non-zero exit code from non-interactive wpa_cli if the
     61 	  command is not recognized or fails
     62 	* fixed 0.5.8 regressions in BSS selection that prevented wildcard SSID
     63 	  from being used with non-WPA networks and disabled workaround for
     64 	  ignoring bogus WPA/RSN IE in non-WPA configuration
     65 	* fixed OpenSSL TLS wrapper to clear trusted CA list to allow
     66 	  network blocks to use different trusted CA configurations
     67 	* fixed a potential EAP state machine loop when mloving from PSK to EAP
     68 	  configuration without restarting wpa_supplicant
     69 
     70 2007-05-28 - v0.5.8
     71 	* updated driver_wext.c to build with the current wireless-dev.git tree
     72 	  and net/d80211 changes
     73 	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
     74 	  draft (draft-ietf-emu-eap-gpsk-03.txt)
     75 	* fixed 'make install'
     76 	* fixed EAP-TTLS implementation not to crash on use of freed memory
     77 	  if TLS library initialization fails
     78 	* fixed EAP-AKA Notification processing to allow Notification to be
     79 	  processed after AKA Challenge response has been sent
     80 
     81 2006-12-31 - v0.5.7
     82 	* updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
     83 	* updated EAP-PSK to use the IANA-allocated EAP type 47
     84 	* fixed EAP-PAX key derivation
     85 	* fixed EAP-PSK bit ordering of the Flags field
     86 	* fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
     87 	  tunnelled identity request (previously, the identifier from the outer
     88 	  method was used, not the tunnelled identifier which could be
     89 	  different)
     90 	* fixed EAP-TTLS AVP parser processing for too short AVP lengths
     91 	* added support for EAP-FAST authentication with inner methods that
     92 	  generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
     93 	  for PAC provisioning)
     94 	* fixed dbus ctrl_iface to validate message interface before
     95 	  dispatching to avoid a possible segfault [Bug 190]
     96 	* fixed PeerKey key derivation to use the correct PRF label
     97 	* updated Windows binary build to link against OpenSSL 0.9.8d and
     98 	  added support for EAP-FAST
     99 
    100 2006-11-24 - v0.5.6
    101 	* added experimental, integrated TLSv1 client implementation with the
    102 	  needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
    103 	  setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
    104 	  .config); this can be useful, e.g., if the target system does not
    105 	  have a suitable TLS library and a minimal code size is required
    106 	  (total size of this internal TLS/crypto code is bit under 50 kB on
    107 	  x86 and the crypto code is shared by rest of the supplicant so some
    108 	  of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
    109 	* removed STAKey handshake since PeerKey handshake has replaced it in
    110 	  IEEE 802.11ma and there are no known deployments of STAKey
    111 	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
    112 	  draft (draft-ietf-emu-eap-gpsk-01.txt)
    113 	* added preliminary implementation of IEEE 802.11w/D1.0 (management
    114 	  frame protection)
    115 	  (Note: this requires driver support to work properly.)
    116 	  (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
    117 	* fixed Windows named pipes ctrl_iface to not stop listening for
    118 	  commands if client program opens a named pipe and closes it
    119 	  immediately without sending a command
    120 	* fixed USIM PIN status determination for the case that PIN is not
    121 	  needed (this allows EAP-AKA to be used with USIM cards that do not
    122 	  use PIN)
    123 	* added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
    124 	  be used with cards that do not support file selection based on
    125 	  partial AID
    126 	* added support for matching the subjectAltName of the authentication
    127 	  server certificate against multiple name components (e.g.,
    128 	  altsubject_match="DNS:server.example.com;DNS:server2.example.com")
    129 	* fixed EAP-SIM/AKA key derivation for re-authentication case (only
    130 	  affects IEEE 802.1X with dynamic WEP keys)
    131 	* changed ctrl_iface network configuration 'get' operations to not
    132 	  return password/key material; if these fields are requested, "*"
    133 	  will be returned if the password/key is set, but the value of the
    134 	  parameter is not exposed
    135 
    136 2006-08-27 - v0.5.5
    137 	* added support for building Windows version with UNICODE defined
    138 	  (wide-char functions)
    139 	* driver_ndis: fixed static WEP configuration to avoid race condition
    140 	  issues with some NDIS drivers between association and setting WEP
    141 	  keys
    142 	* driver_ndis: added validation for IELength value in scan results to
    143 	  avoid crashes when using buggy NDIS drivers [Bug 165]
    144 	* fixed Release|Win32 target in the Visual Studio project files
    145 	  (previously, only Debug|Win32 target was set properly)
    146 	* changed control interface API call wpa_ctrl_pending() to allow it to
    147 	  return -1 on error (e.g., connection lost); control interface clients
    148 	  will need to make sure that they verify that the value is indeed >0
    149 	  when determining whether there are pending messages
    150 	* added an alternative control interface backend for Windows targets:
    151 	  Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
    152 	  control interface mechanism for Windows builds (previously, UDP to
    153 	  localhost was used)
    154 	* changed ctrl_interface configuration for UNIX domain sockets:
    155 	  - deprecated ctrl_interface_group variable (it may be removed in
    156 	    future versions)
    157 	  - allow both directory and group be configured with ctrl_interface
    158 	    in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
    159 	  - ctrl_interface=/var/run/wpa_supplicant is still supported for the
    160 	    case when group is not changed
    161 	* added support for controlling more than one interface per process in
    162 	  Windows version
    163 	* added a workaround for a case where the AP is using unknown address
    164 	  (e.g., MAC address of the wired interface) as the source address for
    165 	  EAPOL-Key frames; previously, that source address was used as the
    166 	  destination for EAPOL-Key frames and in key derivation; now, BSSID is
    167 	  used even if the source address does not match with it
    168 	  (this resolves an interoperability issue with Thomson SpeedTouch 580)
    169 	* added a workaround for UDP-based control interface (which was used in
    170 	  Windows builds before this release) to prevent packets with forged
    171 	  addresses from being accepted as local control requests
    172 	* removed ndis_events.cpp and possibility of using external
    173 	  ndis_events.exe; C version (ndis_events.c) is fully functional and
    174 	  there is no desire to maintain two separate versions of this
    175 	  implementation
    176 	* ndis_events: Changed NDIS event notification design to use WMI to
    177 	  learn the adapter description through Win32_PnPEntity class; this
    178 	  should fix some cases where the adapter name was not recognized
    179 	  correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
    180 	  USB) [Bug 113]
    181 	* fixed selection of the first network in ap_scan=2 mode; previously,
    182 	  wpa_supplicant could get stuck in SCANNING state when only the first
    183 	  network for enabled (e.g., after 'wpa_cli select_network 0')
    184 	* winsvc: added support for configuring ctrl_interface parameters in
    185 	  registry (ctrl_interface string value in
    186 	  HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
    187 	  required to enable control interface (previously, this was hardcoded
    188 	  to be enabled)
    189 	* allow wpa_gui subdirectory to be built with both Qt3 and Qt4
    190 	* converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
    191 
    192 2006-06-20 - v0.5.4
    193 	* fixed build with CONFIG_STAKEY=y [Bug 143]
    194 	* added support for doing MLME (IEEE 802.11 management frame
    195 	  processing) in wpa_supplicant when using Devicescape IEEE 802.11
    196 	  stack (wireless-dev.git tree)
    197 	* added a new network block configuration option, fragment_size, to
    198 	  configure the maximum EAP fragment size
    199 	* driver_ndis: Disable WZC automatically for the selected interface to
    200 	  avoid conflicts with two programs trying to control the radio; WZC
    201 	  will be re-enabled (if it was enabled originally) when wpa_supplicant
    202 	  is terminated
    203 	* added an experimental TLSv1 client implementation
    204 	  (CONFIG_TLS=internal) that can be used instead of an external TLS
    205 	  library, e.g., to reduce total size requirement on systems that do
    206 	  not include any TLS library by default (this is not yet complete;
    207 	  basic functionality is there, but certificate validation is not yet
    208 	  included)
    209 	* added PeerKey handshake implementation for IEEE 802.11e
    210 	  direct link setup (DLS) to replace STAKey handshake
    211 	* fixed WPA PSK update through ctrl_iface for the case where the old
    212 	  PSK was derived from an ASCII passphrase and the new PSK is set as
    213 	  a raw PSK (hex string)
    214 	* added new configuration option for identifying which network block
    215 	  was used (id_str in wpa_supplicant.conf; included on
    216 	  WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
    217 	  variable in wpa_cli action scripts; in addition WPA_ID variable is
    218 	  set to the current unique identifier that wpa_supplicant assigned
    219 	  automatically for the network and that can be used with
    220 	  GET_NETWORK/SET_NETWORK ctrl_iface commands)
    221 	* wpa_cli action script is now called only when the connect/disconnect
    222 	  status changes or when associating with a different network
    223 	* fixed configuration parser not to remove CCMP from group cipher list
    224 	  if WPA-None (adhoc) is used (pairwise=NONE in that case)
    225 	* fixed integrated NDIS events processing not to hang the process due
    226 	  to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
    227 	* added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
    228 	  draft-clancy-emu-eap-shared-secret-00.txt)
    229 	* added Microsoft Visual Studio 2005 solution and project files for
    230 	  build wpa_supplicant for Windows (see vs2005 subdirectory)
    231 	* eloop_win: fixed unregistration of Windows events
    232 	* l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
    233 	  at the end of RSN pre-authentication and added unregistration of
    234 	  a Windows event to avoid getting eloop_win stuck with an invalid
    235 	  handle
    236 	* driver_ndis: added support for selecting AP based on BSSID
    237 	* added new environmental variable for wpa_cli action scripts:
    238 	  WPA_CTRL_DIR is the current control interface directory
    239 	* driver_ndis: added support for using NDISUIO instead of WinPcap for
    240 	  OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
    241 	  l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
    242 	  wpa_supplicant without requiring WinPcap; note that using NDISUIO
    243 	  requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
    244 	  only one application to open the device
    245 	* changed NDIS driver naming to only include device GUID, e.g.,
    246 	  {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
    247 	  specific \Device\NPF_ prefix before the GUID; the prefix is still
    248 	  allowed for backwards compatibility, but it is not required anymore
    249 	  when specifying the interface
    250 	* driver_ndis: re-initialize driver interface is the adapter is removed
    251 	  and re-inserted [Bug 159]
    252 	* driver_madwifi: fixed TKIP and CCMP sequence number configuration on
    253 	  big endian hosts [Bug 146]
    254 
    255 2006-04-27 - v0.5.3
    256 	* fixed EAP-GTC response to include correct user identity when run as
    257 	  phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
    258 	* driver_ndis: Fixed encryption mode configuration for unencrypted
    259 	  networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
    260 	  refused to associate with open networks) [Bug 106]
    261 	* driver_ndis: use BSSID OID polling to detect when IBSS network is
    262 	  formed even when ndis_events code is included since some NDIS drivers
    263 	  do not generate media connect events in IBSS mode
    264 	* config_winreg: allow global ctrl_interface parameter to be configured
    265 	  in Windows registry
    266 	* config_winreg: added support for saving configuration data into
    267 	  Windows registry
    268 	* added support for controlling network device operational state
    269 	  (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
    270 	  http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
    271 	  that can use this information)
    272 	* driver_wext: added support for WE-21 change to SSID configuration
    273 	* driver_wext: fixed privacy configuration for static WEP keys mode
    274 	  [Bug 140]
    275 	* added an optional driver_ops callback for MLME-SETPROTECTION.request
    276 	  primitive
    277 	* added support for EAP-SAKE (no EAP method number allocated yet, so
    278 	  this is using the same experimental type 255 as EAP-PSK)
    279 	* added support for dynamically loading EAP methods (.so files) instead
    280 	  of requiring them to be statically linked in; this is disabled by
    281 	  default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
    282 	  on how to use this)
    283 
    284 2006-03-19 - v0.5.2
    285 	* do not try to use USIM APDUs when initializing PC/SC for SIM card
    286 	  access for a network that has not enabled EAP-AKA
    287 	* fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
    288 	  v0.5.1 due to the new support for expanded EAP types)
    289 	* added support for generating EAP Expanded Nak
    290 	* try to fetch scan results once before requesting new scan when
    291 	  starting up in ap_scan=1 mode (this can speed up initial association
    292 	  a lot with, e.g., madwifi-ng driver)
    293 	* added support for receiving EAPOL frames from a Linux bridge
    294 	  interface (-bbr0 on command line)
    295 	* fixed EAPOL re-authentication for sessions that used PMKSA caching
    296 	* changed EAP method registration to use a dynamic list of methods
    297 	  instead of a static list generated at build time
    298 	* fixed PMKSA cache deinitialization not to use freed memory when
    299 	  removing PMKSA entries
    300 	* fixed a memory leak in EAP-TTLS re-authentication
    301 	* reject WPA/WPA2 message 3/4 if it does not include any valid
    302 	  WPA/RSN IE
    303 	* driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
    304 	  if the driver does not support SIOCSIWAUTH
    305 
    306 2006-01-29 - v0.5.1
    307 	* driver_test: added better support for multiple APs and STAs by using
    308 	  a directory with sockets that include MAC address for each device in
    309 	  the name (driver_param=test_dir=/tmp/test)
    310 	* added support for EAP expanded type (vendor specific EAP methods)
    311 	* added AP_SCAN command into ctrl_iface so that ap_scan configuration
    312 	  option can be changed if needed
    313 	* wpa_cli/wpa_gui: skip non-socket files in control directory when
    314 	  using UNIX domain sockets; this avoids selecting an incorrect
    315 	  interface (e.g., a PID file could be in this directory, even though
    316 	  use of this directory for something else than socket files is not
    317 	  recommended)
    318 	* fixed TLS library deinitialization after RSN pre-authentication not
    319 	  to disable TLS library for normal authentication
    320 	* driver_wext: Remove null-termination from SSID length if the driver
    321 	  used it; some Linux drivers do this and they were causing problems in
    322 	  wpa_supplicant not finding matching configuration block. This change
    323 	  would break a case where the SSID actually ends in '\0', but that is
    324 	  not likely to happen in real use.
    325 	* fixed PMKSA cache processing not to trigger deauthentication if the
    326 	  current PMKSA cache entry is replaced with a valid new entry
    327 	* fixed PC/SC initialization for ap_scan != 1 modes (this fixes
    328 	  EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
    329 	  ap_scan=2)
    330 
    331 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
    332 	* added experimental STAKey handshake implementation for IEEE 802.11e
    333 	  direct link setup (DLS); note: this is disabled by default in both
    334 	  build and runtime configuration (can be enabled with CONFIG_STAKEY=y
    335 	  and stakey=1)
    336 	* fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
    337 	  decrypt AT_ENCR_DATA attributes correctly
    338 	* fixed EAP-AKA to allow resynchronization within the same session
    339 	* made code closer to ANSI C89 standard to make it easier to port to
    340 	  other C libraries and compilers
    341 	* started moving operating system or C library specific functions into
    342 	  wrapper functions defined in os.h and implemented in os_*.c to make
    343 	  code more portable
    344 	* wpa_supplicant can now be built with Microsoft Visual C++
    345 	  (e.g., with the freely available Toolkit 2003 version or Visual
    346 	  C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
    347 	  example makefile for nmake
    348 	* added support for using Windows registry for command line parameters
    349 	  (CONFIG_MAIN=main_winsvc) and configuration data
    350 	  (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
    351 	  contents; this version can be run both as a Windows service and as a
    352 	  normal application; 'wpasvc.exe app' to start as applicant,
    353 	  'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
    354 	  'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
    355 	  unregister a service
    356 	* made it possible to link ndis_events.exe functionality into
    357 	  wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
    358 	* added better support for multiple control interface backends
    359 	  (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
    360 	* fixed PC/SC code to use correct length for GSM AUTH command buffer
    361 	  and to not use pioRecvPci with SCardTransmit() calls; these were not
    362 	  causing visible problems with pcsc-lite, but Windows Winscard.dll
    363 	  refused the previously used parameters; this fixes EAP-SIM and
    364 	  EAP-AKA authentication using SIM/USIM card under Windows
    365 	* added new event loop implementation for Windows using
    366 	  WaitForMultipleObject() instead of select() in order to allow waiting
    367 	  for non-socket objects; this can be selected with
    368 	  CONFIG_ELOOP=eloop_win in .config
    369 	* added support for selecting l2_packet implementation in .config
    370 	  (CONFIG_L2_PACKET; following options are available now: linux, pcap,
    371 	  winpcap, freebsd, none)
    372 	* added new l2_packet implementation for WinPcap
    373 	  (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
    374 	  reduce latency in EAPOL receive processing from about 100 ms to about
    375 	  3 ms
    376 	* added support for EAP-FAST key derivation using other ciphers than
    377 	  RC4-128-SHA for authentication and AES128-SHA for provisioning
    378 	* added support for configuring CA certificate as DER file and as a
    379 	  configuration blob
    380 	* fixed private key configuration as configuration blob and added
    381 	  support for using PKCS#12 as a blob
    382 	* tls_gnutls: added support for using PKCS#12 files; added support for
    383 	  session resumption
    384 	* added support for loading trusted CA certificates from Windows
    385 	  certificate store: ca_cert="cert_store://<name>", where <name> is
    386 	  likely CA (Intermediate CA certificates) or ROOT (root certificates)
    387 	* added C version of ndis_events.cpp and made it possible to build this
    388 	  with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
    389 	  easily on cross-compilation builds
    390 	* added wpasvc.exe into Windows binary release; this is an alternative
    391 	  version of wpa_supplicant.exe with configuration backend using
    392 	  Windows registry and with the entry point designed to run as a
    393 	  Windows service
    394 	* integrated ndis_events.exe functionality into wpa_supplicant.exe and
    395 	  wpasvc.exe and removed this additional tool from the Windows binary
    396 	  release since it is not needed anymore
    397 	* load winscard.dll functions dynamically when building with MinGW
    398 	  since MinGW does not yet include winscard library
    399 
    400 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
    401 	* l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
    402 	  and WinPcap to receive frames sent to PAE group address
    403 	* disable EAP state machine when IEEE 802.1X authentication is not used
    404 	  in order to get rid of bogus "EAP failed" messages
    405 	* fixed OpenSSL error reporting to go through all pending errors to
    406 	  avoid confusing reports of old errors being reported at later point
    407 	  during handshake
    408 	* fixed configuration file updating to not write empty variables
    409 	  (e.g., proto or key_mgmt) that the file parser would not accept
    410 	* fixed ADD_NETWORK ctrl_iface command to use the same default values
    411 	  for variables as empty network definitions read from config file
    412 	  would get
    413 	* fixed EAP state machine to not discard EAP-Failure messages in many
    414 	  cases (e.g., during TLS handshake)
    415 	* fixed a infinite loop in private key reading if the configured file
    416 	  cannot be parsed successfully
    417 	* driver_madwifi: added support for madwifi-ng
    418 	* wpa_gui: do not display password/PSK field contents
    419 	* wpa_gui: added CA certificate configuration
    420 	* driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
    421 	* driver_ndis: include Beacon IEs in AssocInfo in order to notice if
    422 	  the new AP is using different WPA/RSN IE
    423 	* use longer timeout for IEEE 802.11 association to avoid problems with
    424 	  drivers that may take more than five second to associate
    425 
    426 2005-10-27 - v0.4.6
    427 	* allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
    428 	  RSN IE, but WPA IE would match with wpa_supplicant configuration
    429 	* added support for named configuration blobs in order to avoid having
    430 	  to use file system for external files (e.g., certificates);
    431 	  variables can be set to "blob://<blob name>" instead of file path to
    432 	  use a named blob; supported fields: pac_file, client_cert,
    433 	  private_key
    434 	* fixed RSN pre-authentication (it was broken in the clean up of WPA
    435 	  state machine interface in v0.4.5)
    436 	* driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
    437 	  sure the driver configures broadcast decryption correctly
    438 	* added ca_path (and ca_path2) configuration variables that can be used
    439 	  to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
    440 	  system-wide trusted CA list
    441 	* added support for starting wpa_supplicant without a configuration
    442 	  file (-C argument must be used to set ctrl_interface parameter for
    443 	  this case; in addition, -p argument can be used to provide
    444 	  driver_param; these new arguments can also be used with a
    445 	  configuration to override the values from the configuration)
    446 	* added global control interface that can be optionally used for adding
    447 	  and removing network interfaces dynamically (-g command line argument
    448 	  for both wpa_supplicant and wpa_cli) without having to restart
    449 	  wpa_supplicant process
    450 	* wpa_gui:
    451 	  - try to save configuration whenever something is modified
    452 	  - added WEP key configuration
    453 	  - added possibility to edit the current network configuration
    454 	* driver_ndis: fixed driver polling not to increase frequency on each
    455 	  received EAPOL frame due to incorrectly cancelled timeout
    456 	* added simple configuration file examples (in examples subdirectory)
    457 	* fixed driver_wext.c to filter wireless events based on ifindex to
    458 	  avoid interfaces receiving events from other interfaces
    459 	* delay sending initial EAPOL-Start couple of seconds to speed up
    460 	  authentication for the most common case of Authenticator starting
    461 	  EAP authentication immediately after association
    462 
    463 2005-09-25 - v0.4.5
    464 	* added a workaround for clearing keys with ndiswrapper to allow
    465 	  roaming from WPA enabled AP to plaintext one
    466 	* added docbook documentation (doc/docbook) that can be used to
    467 	  generate, e.g., man pages
    468 	* l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
    469 	  PF_PACKET in order to prepare for network devices that do not use
    470 	  Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
    471 	* use receipt of EAPOL-Key frame as a lower layer success indication
    472 	  for EAP state machine to allow recovery from dropped EAP-Success
    473 	  frame
    474 	* cleaned up internal EAPOL frame processing by not including link
    475 	  layer (Ethernet) header during WPA and EAPOL/EAP processing; this
    476 	  header is added only when transmitted the frame; this makes it easier
    477 	  to use wpa_supplicant on link layers that use different header than
    478 	  Ethernet
    479 	* updated EAP-PSK to use draft 9 by default since this can now be
    480 	  tested with hostapd; removed support for draft 3, including
    481 	  server_nai configuration option from network blocks
    482 	* driver_wired: add PAE address to the multicast address list in order
    483 	  to be able to receive EAPOL frames with drivers that do not include
    484 	  these multicast addresses by default
    485 	* driver_wext: add support for WE-19
    486 	* added support for multiple configuration backends (CONFIG_BACKEND
    487 	  option); currently, only 'file' is supported (i.e., the format used
    488 	  in wpa_supplicant.conf)
    489 	* added support for updating configuration ('wpa_cli save_config');
    490 	  this is disabled by default and can be enabled with global
    491 	  update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
    492 	  and wpa_gui to store the configuration changes in a permanent store
    493 	* added GET_NETWORK ctrl_iface command
    494 	  (e.g., 'wpa_cli get_network 0 ssid')
    495 
    496 2005-08-21 - v0.4.4
    497 	* replaced OpenSSL patch for EAP-FAST support
    498 	  (openssl-tls-extensions.patch) with a more generic and correct
    499 	  patch (the new patch is not compatible with the previous one, so the
    500 	  OpenSSL library will need to be patched with the new patch in order
    501 	  to be able to build wpa_supplicant with EAP-FAST support)
    502 	* added support for using Windows certificate store (through CryptoAPI)
    503 	  for client certificate and private key operations (EAP-TLS)
    504 	  (see wpa_supplicant.conf for more information on how to configure
    505 	  this with private_key)
    506 	* ported wpa_gui to Windows
    507 	* added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
    508 	  built with the open source version of the Qt4 for Windows
    509 	* allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
    510 	  with drivers that do not support WPA
    511 	* ndis_events: fixed Windows 2000 support
    512 	* added support for enabling/disabling networks from the list of all
    513 	  configured networks ('wpa_cli enable_network <network id>' and
    514 	  'wpa_cli disable_network <network id>')
    515 	* added support for adding and removing network from the current
    516 	  configuration ('wpa_cli add_network' and 'wpa_cli remove_network
    517 	  <network id>'); added networks are disabled by default and they can
    518 	  be enabled with enable_network command once the configuration is done
    519 	  for the new network; note: configuration file is not yet updated, so
    520 	  these new networks are lost when wpa_supplicant is restarted
    521 	* added support for setting network configuration parameters through
    522 	  the control interface, for example:
    523 	  wpa_cli set_network 0 ssid "\"my network\""
    524 	* fixed parsing of strings that include both " and # within double
    525 	  quoted area (e.g., "start"#end")
    526 	* added EAP workaround for PEAP session resumption: allow outer,
    527 	  i.e., not tunneled, EAP-Success to terminate session since; this can
    528 	  be disabled with eap_workaround=0
    529 	  (this was allowed for PEAPv1 before, but now it is also allowed for
    530 	  PEAPv0 since at least one RADIUS authentication server seems to be
    531 	  doing this for PEAPv0, too)
    532 	* wpa_gui: added preliminary support for adding new networks to the
    533 	  wpa_supplicant configuration (double click on the scan results to
    534 	  open network configuration)
    535 
    536 2005-06-26 - v0.4.3
    537 	* removed interface for external EAPOL/EAP supplicant (e.g.,
    538 	  Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
    539 	  anymore and is unlikely to be used by anyone
    540 	* driver_ndis: fixed WinPcap 3.0 support
    541 	* fixed build with CONFIG_DNET_PCAP=y on Linux
    542 	* l2_packet: moved different implementations into separate files
    543 	  (l2_packet_*.c)
    544 
    545 2005-06-12 - v0.4.2
    546 	* driver_ipw: updated driver structures to match with ipw2200-1.0.4
    547 	  (note: ipw2100-1.1.0 is likely to require an update to work with
    548 	  this)
    549 	* added support for using ap_scan=2 mode with multiple network blocks;
    550 	  wpa_supplicant will go through the networks one by one until the
    551 	  driver reports a successful association; this uses the same order for
    552 	  networks as scan_ssid=1 scans, i.e., the priority field is ignored
    553 	  and the network block order in the file is used instead
    554 	* fixed a potential issue in RSN pre-authentication ending up using
    555 	  freed memory if pre-authentication times out
    556 	* added support for matching alternative subject name extensions of the
    557 	  authentication server certificate; new configuration variables
    558 	  altsubject_match and altsubject_match2
    559 	* driver_ndis: added support for IEEE 802.1X authentication with wired
    560 	  NDIS drivers
    561 	* added support for querying private key password (EAP-TLS) through the
    562 	  control interface (wpa_cli/wpa_gui) if one is not included in the
    563 	  configuration file
    564 	* driver_broadcom: fixed couple of memory leaks in scan result
    565 	  processing
    566 	* EAP-PAX is now registered as EAP type 46
    567 	* fixed EAP-PAX MAC calculation
    568 	* fixed EAP-PAX CK and ICK key derivation
    569 	* added support for using password with EAP-PAX (as an alternative to
    570 	  entering key with eappsk); SHA-1 hash of the password will be used as
    571 	  the key in this case
    572 	* added support for arbitrary driver interface parameters through the
    573 	  configuration file with a new driver_param field; this adds a new
    574 	  driver_ops function set_param()
    575 	* added possibility to override l2_packet module with driver interface
    576 	  API (new send_eapol handler); this can be used to implement driver
    577 	  specific TX/RX functions for EAPOL frames
    578 	* fixed ctrl_interface_group processing for the case where gid is
    579 	  entered as a number, not group name
    580 	* driver_test: added support for testing hostapd with wpa_supplicant
    581 	  by using test driver interface without any kernel drivers or network
    582 	  cards
    583 
    584 2005-05-22 - v0.4.1
    585 	* driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
    586 	  packets to be encrypted; this was apparently broken by the changed
    587 	  ioctl order in v0.4.0
    588 	* driver_madwifi: added preliminary support for compiling against 'BSD'
    589 	  branch of madwifi CVS tree
    590 	* added support for EAP-MSCHAPv2 password retries within the same EAP
    591 	  authentication session
    592 	* added support for password changes with EAP-MSCHAPv2 (used when the
    593 	  password has expired)
    594 	* added support for reading additional certificates from PKCS#12 files
    595 	  and adding them to the certificate chain
    596 	* fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
    597 	  were used
    598 	* fixed a possible double free in EAP-TTLS fast-reauthentication when
    599 	  identity or password is entered through control interface
    600 	* display EAP Notification messages to user through control interface
    601 	  with "CTRL-EVENT-EAP-NOTIFICATION" prefix
    602 	* added GUI version of wpa_cli, wpa_gui; this is not build
    603 	  automatically with 'make'; use 'make wpa_gui' to build (this requires
    604 	  Qt development tools)
    605 	* added 'disconnect' command to control interface for setting
    606 	  wpa_supplicant in state where it will not associate before
    607 	  'reassociate' command has been used
    608 	* added support for selecting a network from the list of all configured
    609 	  networks ('wpa_cli select_network <network id>'; this disabled all
    610 	  other networks; to re-enable, 'wpa_cli select_network any')
    611 	* added support for getting scan results through control interface
    612 	* added EAP workaround for PEAPv1 session resumption: allow outer,
    613 	  i.e., not tunneled, EAP-Success to terminate session since; this can
    614 	  be disabled with eap_workaround=0
    615 
    616 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
    617 	* added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
    618 	  used to reduce the size of the wpa_supplicant considerably if
    619 	  debugging code is not needed
    620 	* fixed EAPOL-Key validation to drop packets with invalid Key Data
    621 	  Length; such frames could have crashed wpa_supplicant due to buffer
    622 	  overflow
    623 	* added support for wired authentication (IEEE 802.1X on wired
    624 	  Ethernet); driver interface 'wired'
    625 	* obsoleted set_wpa() handler in the driver interface API (it can be
    626 	  replaced by moving enable/disable functionality into init()/deinit())
    627 	  (calls to set_wpa() are still present for backwards compatibility,
    628 	  but they may be removed in the future)
    629 	* driver_madwifi: fixed association in plaintext mode
    630 	* modified the EAP workaround that accepts EAP-Success with incorrect
    631 	  Identifier to be even less strict about verification in order to
    632 	  interoperate with some authentication servers
    633 	* added support for sending TLS alerts
    634 	* added support for 'any' SSID wildcard; if ssid is not configured or
    635 	  is set to an empty string, any SSID will be accepted for non-WPA AP
    636 	* added support for asking PIN (for SIM) from frontends (e.g.,
    637 	  wpa_cli); if a PIN is needed, but not included in the configuration
    638 	  file, a control interface request is sent and EAP processing is
    639 	  delayed until the PIN is available
    640 	* added support for using external devices (e.g., a smartcard) for
    641 	  private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
    642 	  new wpa_supplicant.conf variables:
    643 	  - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
    644 	  - network: engine, engine_id, key_id
    645 	* added experimental support for EAP-PAX
    646 	* added monitor mode for wpa_cli (-a<path to a program to run>) that
    647 	  allows external commands (e.g., shell scripts) to be run based on
    648 	  wpa_supplicant events, e.g., when authentication has been completed
    649 	  and data connection is ready; other related wpa_cli arguments:
    650 	  -B (run in background), -P (write PID file); wpa_supplicant has a new
    651 	  command line argument (-W) that can be used to make it wait until a
    652 	  control interface command is received in order to avoid missing
    653 	  events
    654 	* added support for opportunistic WPA2 PMKSA key caching (disabled by
    655 	  default, can be enabled with proactive_key_caching=1)
    656 	* fixed RSN IE in 4-Way Handshake message 2/4 for the case where
    657 	  Authenticator rejects PMKSA caching attempt and the driver is not
    658 	  using assoc_info events
    659 	* added -P<pid file> argument for wpa_supplicant to write the current
    660 	  process id into a file
    661 
    662 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
    663 	* added new phase1 option parameter, include_tls_length=1, to force
    664 	  wpa_supplicant to add TLS Message Length field to all TLS messages
    665 	  even if the packet is not fragmented; this may be needed with some
    666 	  authentication servers
    667 	* fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
    668 	  using drivers that take care of AP selection (e.g., when using
    669 	  ap_scan=2)
    670 	* fixed reprocessing of pending request after ctrl_iface requests for
    671 	  identity/password/otp
    672 	* fixed ctrl_iface requests for identity/password/otp in Phase 2 of
    673 	  EAP-PEAP and EAP-TTLS
    674 	* all drivers using driver_wext: set interface up and select Managed
    675 	  mode when starting wpa_supplicant; set interface down when exiting
    676 	* renamed driver_ipw2100.c to driver_ipw.c since it now supports both
    677 	  ipw2100 and ipw2200; please note that this also changed the
    678 	  configuration variable in .config to CONFIG_DRIVER_IPW
    679 
    680 2005-01-24 - v0.3.6
    681 	* fixed a busy loop introduced in v0.3.5 for scan result processing
    682 	  when no matching AP is found
    683 
    684 2005-01-23 - v0.3.5
    685 	* added a workaround for an interoperability issue with a Cisco AP
    686 	  when using WPA2-PSK
    687 	* fixed non-WPA IEEE 802.1X to use the same authentication timeout as
    688 	  WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
    689 	  retransmission of dropped frames)
    690 	* fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
    691 	  (e.g., segfault when processing EAPOL-Key frames)
    692 	* fixed EAP workaround and fast reauthentication configuration for
    693 	  RSN pre-authentication; previously these were disabled and
    694 	  pre-authentication would fail if the used authentication server
    695 	  requires EAP workarounds
    696 	* added support for blacklisting APs that fail or timeout
    697 	  authentication in ap_scan=1 mode so that all APs are tried in cases
    698 	  where the ones with strongest signal level are failing authentication
    699 	* fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
    700 	  authentication attempt
    701 	* allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
    702 	  in the previous authentication (previously, only Phase 1 success was
    703 	  verified)
    704 
    705 2005-01-09 - v0.3.4
    706 	* added preliminary support for IBSS (ad-hoc) mode configuration
    707 	  (mode=1 in network block); this included a new key_mgmt mode
    708 	  WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
    709 	  key management; see wpa_supplicant.conf for more details and an
    710 	  example on how to configure this (note: this is currently implemented
    711 	  only for driver_hostapd.c, but the changes should be trivial to add
    712 	  in associate() handler for other drivers, too (assuming the driver
    713 	  supports WPA-None)
    714 	* added preliminary port for native Windows (i.e., no cygwin) using
    715 	  mingw
    716 
    717 2005-01-02 - v0.3.3
    718 	* added optional support for GNU Readline and History Libraries for
    719 	  wpa_cli (CONFIG_READLINE)
    720 	* cleaned up EAP state machine <-> method interface and number of
    721 	  small problems with error case processing not terminating on
    722 	  EAP-Failure but waiting for timeout
    723 	* added couple of workarounds for interoperability issues with a
    724 	  Cisco AP when using WPA2
    725 	* added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
    726 	  Note: This requires a patch for openssl to add support for TLS
    727 	  extensions and number of workarounds for operations without
    728 	  certificates. Proof of concept type of experimental patch is
    729 	  included in openssl-tls-extensions.patch.
    730 
    731 2004-12-19 - v0.3.2
    732 	* fixed private key loading for cases where passphrase is not set
    733 	* fixed Windows/cygwin L2 packet handler freeing; previous version
    734 	  could cause a segfault when RSN pre-authentication was completed
    735 	* added support for PMKSA caching with drivers that generate RSN IEs
    736 	  (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
    737 	  but similar code can be easily added to driver_ndiswrapper.c once
    738 	  ndiswrapper gets full support for RSN PMKSA caching
    739 	* improved recovery from PMKID mismatches by requesting full EAP
    740 	  authentication in case of failed PMKSA caching attempt
    741 	* driver_ndis: added support for NDIS NdisMIncidateStatus() events
    742 	  (this requires that ndis_events is ran while wpa_supplicant is
    743 	  running)
    744 	* driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
    745 	* added support for driver interfaces to replace the interface name
    746 	  based on driver/OS specific mapping, e.g., in case of driver_ndis,
    747 	  this allows the beginning of the adapter description to be used as
    748 	  the interface name
    749 	* added support for CR+LF (Windows-style) line ends in configuration
    750 	  file
    751 	* driver_ndis: enable radio before starting scanning, disable radio
    752 	  when exiting
    753 	* modified association event handler to set portEnabled = FALSE before
    754 	  clearing port Valid in order to reset EAP state machine and avoid
    755 	  problems with new authentication getting ignored because of state
    756 	  machines ending up in AUTHENTICATED/SUCCESS state based on old
    757 	  information
    758 	* added support for driver events to add PMKID candidates in order to
    759 	  allow drivers to give priority to most likely roaming candidates
    760 	* driver_hostap: moved PrivacyInvoked configuration to associate()
    761 	  function so that this will not be set for plaintext connections
    762 	* added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
    763 	  interface can distinguish plaintext and IEEE 802.1X (no WPA)
    764 	  authentication
    765 	* fixed static WEP key configuration to use broadcast/default type for
    766 	  all keys (previously, the default TX key was configured as pairwise/
    767 	  unicast key)
    768 	* driver_ndis: added legacy WPA capability detection for non-WPA2
    769 	  drivers
    770 	* added support for setting static WEP keys for IEEE 802.1X without
    771 	  dynamic WEP keying (eapol_flags=0)
    772 
    773 2004-12-12 - v0.3.1
    774 	* added support for reading PKCS#12 (PFX) files (as a replacement for
    775 	  PEM/DER) to get certificate and private key (CONFIG_PKCS12)
    776 	* fixed compilation with CONFIG_PCSC=y
    777 	* added new ap_scan mode, ap_scan=2, for drivers that take care of
    778 	  association, but need to be configured with security policy and SSID,
    779 	  e.g., ndiswrapper and NDIS driver; this mode should allow such
    780 	  drivers to work with hidden SSIDs and optimized roaming; when
    781 	  ap_scan=2 is used, only the first network block in the configuration
    782 	  file is used and this configuration should have explicit security
    783 	  policy (i.e., only one option in the lists) for key_mgmt, pairwise,
    784 	  group, proto variables
    785 	* added experimental port of wpa_supplicant for Windows
    786 	  - driver_ndis.c driver interface (NDIS OIDs)
    787 	  - currently, this requires cygwin and WinPcap
    788 	  - small utility, win_if_list, can be used to get interface name
    789 	* control interface can now be removed at build time; add
    790 	  CONFIG_CTRL_IFACE=y to .config to maintain old functionality
    791 	* optional Xsupplicant interface can now be removed at build time;
    792 	  (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
    793 	* added auth_alg to driver interface associate() parameters to make it
    794 	  easier for drivers to configure authentication algorithm as part of
    795 	  the association
    796 
    797 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
    798 	* driver_broadcom: added new driver interface for Broadcom wl.o driver
    799 	  (a generic driver for Broadcom IEEE 802.11a/g cards)
    800 	* wpa_cli: fixed parsing of -p <path> command line argument
    801 	* PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
    802 	  ACK, not tunneled EAP-Success (of which only the first byte was
    803 	  actually send due to a bug in previous code); this seems to
    804 	  interoperate with most RADIUS servers that implements PEAPv1
    805 	* PEAPv1: added support for terminating PEAP authentication on tunneled
    806 	  EAP-Success message; this can be configured by adding
    807 	  peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
    808 	  (some RADIUS servers require this whereas others require a tunneled
    809 	  reply
    810 	* PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
    811 	  the old label for key derivation; previously, the default was 1,
    812 	  but it looks like most existing PEAPv1 implementations use the old
    813 	  label which is thus more suitable default option
    814 	* added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
    815 	* fixed parsing of wep_tx_keyidx
    816 	* added support for configuring list of allowed Phase 2 EAP types
    817 	  (for both EAP-PEAP and EAP-TTLS) instead of only one type
    818 	* added support for configuring IEEE 802.11 authentication algorithm
    819 	  (auth_alg; mainly for using Shared Key authentication with static
    820 	  WEP keys)
    821 	* added support for EAP-AKA (with UMTS SIM)
    822 	* fixed couple of errors in PCSC handling that could have caused
    823 	  random-looking errors for EAP-SIM
    824 	* added support for EAP-SIM pseudonyms and fast re-authentication
    825 	* added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
    826 	  session resumption)
    827 	* added support for EAP-SIM with two challanges
    828 	  (phase1="sim_min_num_chal=3" can be used to require three challenges)
    829 	* added support for configuring DH/DSA parameters for an ephemeral DH
    830 	  key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
    831 	  dh_file and dh_file2 (phase 2); this adds support for using DSA keys
    832 	  and optional DH key exchange to achieve forward secracy with RSA keys
    833 	* added support for matching subject of the authentication server
    834 	  certificate with a substring when using EAP-TLS/PEAP/TTLS; new
    835 	  configuration variables subject_match and subject_match2
    836 	* changed SSID configuration in driver_wext.c (used by many driver
    837 	  interfaces) to use ssid_len+1 as the length for SSID since some Linux
    838 	  drivers expect this
    839 	* fixed couple of unaligned reads in scan result parsing to fix WPA
    840 	  connection on some platforms (e.g., ARM)
    841 	* added driver interface for Intel ipw2100 driver
    842 	* added support for LEAP with WPA
    843 	* added support for larger scan results report (old limit was 4 kB of
    844 	  data, i.e., about 35 or so APs) when using Linux wireless extensions
    845 	  v17 or newer
    846 	* fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
    847 	  only if there is a PMKSA cache entry for the current AP
    848 	* fixed error handling for case where reading of scan results fails:
    849 	  must schedule a new scan or wpa_supplicant will remain waiting
    850 	  forever
    851 	* changed debug output to remove shared password/key material by
    852 	  default; all key information can be included with -K command line
    853 	  argument to match the previous behavior
    854 	* added support for timestamping debug log messages (disabled by
    855 	  default, can be enabled with -t command line argument)
    856 	* set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
    857 	  if keys are not configured to be used; this fixes IEEE 802.1X mode
    858 	  with drivers that use this information to configure whether Privacy
    859 	  bit can be in Beacon frames (e.g., ndiswrapper)
    860 	* avoid clearing driver keys if no keys have been configured since last
    861 	  key clear request; this seems to improve reliability of group key
    862 	  handshake for ndiswrapper & NDIS driver which seems to be suffering
    863 	  of some kind of timing issue when the keys are cleared again after
    864 	  association
    865 	* changed driver interface API:
    866 	  - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
    867 	    version is being used (now, this is set to 2; previously, it was
    868 	    not defined)
    869 	  - pass pointer to private data structure to all calls
    870 	  - the new API is not backwards compatible; all in-tree driver
    871 	    interfaces has been converted to the new API
    872 	* added support for controlling multiple interfaces (radios) per
    873 	  wpa_supplicant process; each interface needs to be listed on the
    874 	  command line (-c, -i, -D arguments) with -N as a separator
    875 	  (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
    876 	* added a workaround for EAP servers that incorrectly use same Id for
    877 	  sequential EAP packets
    878 	* changed libpcap/libdnet configuration to use .config variable,
    879 	  CONFIG_DNET_PCAP, instead of requiring Makefile modification
    880 	* improved downgrade attack detection in IE verification of msg 3/4:
    881 	  verify both WPA and RSN IEs, if present, not only the selected one;
    882 	  reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
    883 	  Probe Response frame, and RSN is enabled in wpa_supplicant
    884 	  configuration
    885 	* fixed WPA msg 3/4 processing to allow Key Data field contain other
    886 	  IEs than just one WPA IE
    887 	* added support for FreeBSD and driver interface for the BSD net80211
    888 	  layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
    889 	  required kernel mods have not yet been committed
    890 	* made EAP workarounds configurable; enabled by default, can be
    891 	  disabled with network block option eap_workaround=0
    892 
    893 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
    894 	* resolved couple of interoperability issues with EAP-PEAPv1 and
    895 	  Phase 2 (inner EAP) fragment reassembly
    896 	* driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
    897 	  AP is using non-zero key index for the unicast key and key index zero
    898 	  for the broadcast key
    899 	* driver_hostap: fixed IEEE 802.1X WEP key updates and
    900 	  re-authentication by allowing unencrypted EAPOL frames when not using
    901 	  WPA
    902 	* added a new driver interface, 'wext', which uses only standard,
    903 	  driver independent functionality in Linux wireless extensions;
    904 	  currently, this can be used only for non-WPA IEEE 802.1X mode, but
    905 	  eventually, this is to be extended to support full WPA/WPA2 once
    906 	  Linux wireless extensions get support for this
    907 	* added support for mode in which the driver is responsible for AP
    908 	  scanning and selection; this is disabled by default and can be
    909 	  enabled with global ap_scan=0 variable in wpa_supplicant.conf;
    910 	  this mode can be used, e.g., with generic 'wext' driver interface to
    911 	  use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
    912 	  supporting wireless extensions.
    913 	* driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
    914 	  operation with an AP that does not include SSID in the Beacon frames)
    915 	* added support for new EAP authentication methods:
    916 	  EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
    917 	* added support for asking one-time-passwords from frontends (e.g.,
    918 	  wpa_cli); this 'otp' command works otherwise like 'password' command,
    919 	  but the password is used only once and the frontend will be asked for
    920 	  a new password whenever a request from authenticator requires a
    921 	  password; this can be used with both EAP-OTP and EAP-GTC
    922 	* changed wpa_cli to automatically re-establish connection so that it
    923 	  does not need to be re-started when wpa_supplicant is terminated and
    924 	  started again
    925 	* improved user data (identity/password/otp) requests through
    926 	  frontends: process pending EAPOL packets after getting new
    927 	  information so that full authentication does not need to be
    928 	  restarted; in addition, send pending requests again whenever a new
    929 	  frontend is attached
    930 	* changed control frontends to use a new directory for socket files to
    931 	  make it easier for wpa_cli to automatically select between interfaces
    932 	  and to provide access control for the control interface;
    933 	  wpa_supplicant.conf: ctrl_interface is now a path
    934 	  (/var/run/wpa_supplicant is the recommended path) and
    935 	  ctrl_interface_group can be used to select which group gets access to
    936 	  the control interface;
    937 	  wpa_cli: by default, try to connect to the first interface available
    938 	  in /var/run/wpa_supplicant; this path can be overriden with -p option
    939 	  and an interface can be selected with -i option (i.e., in most common
    940 	  cases, wpa_cli does not need to get any arguments)
    941 	* added support for LEAP
    942 	* added driver interface for Linux ndiswrapper
    943 	* added priority option for network blocks in the configuration file;
    944 	  this allows networks to be grouped based on priority (the scan
    945 	  results are searched for matches with network blocks in this order)
    946 
    947 2004-06-20 - v0.2.3
    948 	* sort scan results to improve AP selection
    949 	* fixed control interface socket removal for some error cases
    950 	* improved scan requesting and authentication timeout
    951 	* small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
    952 	  TLS processing
    953 	* PEAP version can now be forced with phase1="peapver=<ver>"
    954 	  (mostly for testing; by default, the highest version supported by
    955 	  both the Supplicant and Authentication Server is selected
    956 	  automatically)
    957 	* added support for madwifi driver (Atheros ar521x)
    958 	* added a workaround for cases where AP sets Install Tx/Rx bit for
    959 	  WPA Group Key messages when pairwise keys are used (without this,
    960 	  the Group Key would be used for Tx and the AP would drop frames
    961 	  from the station)
    962 	* added GSM SIM/USIM interface for GSM authentication algorithm for
    963 	  EAP-SIM; this requires pcsc-lite
    964 	* added support for ATMEL AT76C5XXx driver
    965 	* fixed IEEE 802.1X WEP key derivation in the case where Authenticator
    966 	  does not include key data in the EAPOL-Key frame (i.e., part of
    967 	  EAP keying material is used as data encryption key)
    968 	* added support for using plaintext and static WEP networks
    969 	  (key_mgmt=NONE)
    970 
    971 2004-05-31 - v0.2.2
    972 	* added support for new EAP authentication methods:
    973 	  EAP-TTLS/EAP-MD5-Challenge
    974 	  EAP-TTLS/EAP-GTC
    975 	  EAP-TTLS/EAP-MSCHAPv2
    976 	  EAP-TTLS/EAP-TLS
    977 	  EAP-TTLS/MSCHAPv2
    978 	  EAP-TTLS/MSCHAP
    979 	  EAP-TTLS/PAP
    980 	  EAP-TTLS/CHAP
    981 	  EAP-PEAP/TLS
    982 	  EAP-PEAP/GTC
    983 	  EAP-PEAP/MD5-Challenge
    984 	  EAP-GTC
    985 	  EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
    986 	* added support for anonymous identity (to be used when identity is
    987 	  sent in plaintext; real identity will be used within TLS protected
    988 	  tunnel (e.g., with EAP-TTLS)
    989 	* added event messages from wpa_supplicant to frontends, e.g., wpa_cli
    990 	* added support for requesting identity and password information using
    991 	  control interface; in other words, the password for EAP-PEAP or
    992 	  EAP-TTLS does not need to be included in the configuration file since
    993 	  a frontand (e.g., wpa_cli) can ask it from the user
    994 	* improved RSN pre-authentication to use a candidate list and process
    995 	  all candidates from each scan; not only one per scan
    996 	* fixed RSN IE and WPA IE capabilities field parsing
    997 	* ignore Tx bit in GTK IE when Pairwise keys are used
    998 	* avoid making new scan requests during IEEE 802.1X negotiation
    999 	* use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
   1000 	  with TLS support (this replaces the included implementation with
   1001 	  library code to save about 8 kB since the library code is needed
   1002 	  anyway for TLS)
   1003 	* fixed WPA-PSK only mode when compiled without IEEE 802.1X support
   1004 	  (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
   1005 
   1006 2004-05-06 - v0.2.1
   1007 	* added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
   1008 	  Supplicant
   1009 	  - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
   1010 	  - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
   1011 	  - EAP-MD5 (cannot be used with WPA-RADIUS)
   1012 	    [draft-ietf-eap-rfc2284bis-09.txt]
   1013 	  - EAP-TLS [RFC 2716]
   1014 	  - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
   1015 	  - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
   1016 	    [draft-kamath-pppext-eap-mschapv2-00.txt]
   1017 	    (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
   1018 	    default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
   1019 	  - new configuration file options: eap, identity, password, ca_cert,
   1020 	    client_cert, privatekey, private_key_passwd
   1021 	  - Xsupplicant is not required anymore, but it can be used by
   1022 	    disabling the internal IEEE 802.1X Supplicant with -e command line
   1023 	    option
   1024 	  - this code is not included in the default build; Makefile need to
   1025 	    be edited for this (uncomment lines for selected functionality)
   1026 	  - EAP-TLS and EAP-PEAP require openssl libraries
   1027 	* use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
   1028 	* added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
   1029 	  (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
   1030 	   EAPOL-Key frames instead of WPA key handshakes)
   1031 	* added support for IEEE 802.11i/RSN (WPA2)
   1032 	  - improved PTK Key Handshake
   1033 	  - PMKSA caching, pre-authentication
   1034 	* fixed wpa_supplicant to ignore possible extra data after WPA
   1035 	  EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
   1036 	  TPTK' error from message 3 of 4-Way Handshake in case the AP
   1037 	  includes extra data after the EAPOL-Key)
   1038 	* added interface for external programs (frontends) to control
   1039 	  wpa_supplicant
   1040 	  - CLI example (wpa_cli) with interactive mode and command line
   1041 	    mode
   1042 	  - replaced SIGUSR1 status/statistics with the new control interface
   1043 	* made some feature compile time configurable
   1044 	  - .config file for make
   1045 	  - driver interfaces (hostap, hermes, ..)
   1046 	  - EAPOL/EAP functions
   1047 
   1048 2004-02-15 - v0.2.0
   1049 	* Initial version of wpa_supplicant
   1050
