      1 ChangeLog for wpa_supplicant
      2 
      3 2010-04-18 - v0.7.2
      4 	* nl80211: fixed number of issues with roaming
      5 	* avoid unnecessary roaming if multiple APs with similar signal
      6 	  strength are present in scan results
      7 	* add TLS client events and server probing to ease design of
      8 	  automatic detection of EAP parameters
      9 	* add option for server certificate matching (SHA256 hash of the
     10 	  certificate) instead of trusted CA certificate configuration
     11 	* bsd: Cleaned up driver wrapper and added various low-level
     12 	  configuration options
     13 	* wpa_gui-qt4: do not show too frequent WPS AP available events as
     14 	  tray messages
     15 	* TNC: fixed issues with fragmentation
     16 	* EAP-TNC: add Flags field into fragment acknowledgement (needed to
     17 	  interoperate with other implementations; may potentially breaks
     18 	  compatibility with older wpa_supplicant/hostapd versions)
     19 	* wpa_cli: added option for using a separate process to receive event
     20 	  messages to reduce latency in showing these
     21 	  (CFLAGS += -DCONFIG_WPA_CLI_FORK=y in .config to enable this)
     22 	* maximum BSS table size can now be configured (bss_max_count)
     23 	* BSSes to be included in the BSS table can be filtered based on
     24 	  configured SSIDs to save memory (filter_ssids)
     25 	* fix number of issues with IEEE 802.11r/FT; this version is not
     26 	  backwards compatible with old versions
     27 	* nl80211: add support for IEEE 802.11r/FT protocol (both over-the-air
     28 	  and over-the-DS)
     29 	* add freq_list network configuration parameter to allow the AP
     30 	  selection to filter out entries based on the operating channel
     31 	* add signal strength change events for bgscan; this allows more
     32 	  dynamic changes to background scanning interval based on changes in
     33 	  the signal strength with the current AP; this improves roaming within
     34 	  ESS quite a bit, e.g., with bgscan="simple:30:-45:300" in the network
     35 	  configuration block to request background scans less frequently when
     36 	  signal strength remains good and to automatically trigger background
     37 	  scans whenever signal strength drops noticeably
     38 	  (this is currently only available with nl80211)
     39 	* add BSSID and reason code (if available) to disconnect event messages
     40 	* wpa_gui-qt4: more complete support for translating the GUI with
     41 	  linguist and add German translation
     42 	* fix DH padding with internal crypto code (mainly, for WPS)
     43 	* do not trigger initial scan automatically anymore if there are no
     44 	  enabled networks
     45 
     46 2010-01-16 - v0.7.1
     47 	* cleaned up driver wrapper API (struct wpa_driver_ops); the new API
     48 	  is not fully backwards compatible, so out-of-tree driver wrappers
     49 	  will need modifications
     50 	* cleaned up various module interfaces
     51 	* merge hostapd and wpa_supplicant developers' documentation into a
     52 	  single document
     53 	* nl80211: use explicit deauthentication to clear cfg80211 state to
     54 	  avoid issues when roaming between APs
     55 	* dbus: major design changes in the new D-Bus API
     56 	  (fi.w1.wpa_supplicant1)
     57 	* nl80211: added support for IBSS networks
     58 	* added internal debugging mechanism with backtrace support and memory
     59 	  allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y)
     60 	* added WPS ER unsubscription command to more cleanly unregister from
     61 	  receiving UPnP events when ER is terminated
     62 	* cleaned up AP mode operations to avoid need for virtual driver_ops
     63 	  wrapper
     64 	* added BSS table to maintain more complete scan result information
     65 	  over multiple scans (that may include only partial results)
     66 	* wpa_gui-qt4: update Peers dialog information more dynamically while
     67 	  the dialog is kept open
     68 	* fixed PKCS#12 use with OpenSSL 1.0.0
     69 	* driver_wext: Added cfg80211-specific optimization to avoid some
     70 	  unnecessary scans and to speed up association
     71 
     72 2009-11-21 - v0.7.0
     73 	* increased wpa_cli ping interval to 5 seconds and made this
     74 	  configurable with a new command line options (-G<seconds>)
     75 	* fixed scan buffer processing with WEXT to handle up to 65535
     76 	  byte result buffer (previously, limited to 32768 bytes)
     77 	* allow multiple driver wrappers to be specified on command line
     78 	  (e.g., -Dnl80211,wext); the first one that is able to initialize the
     79 	  interface will be used
     80 	* added support for multiple SSIDs per scan request to optimize
     81 	  scan_ssid=1 operations in ap_scan=1 mode (i.e., search for hidden
     82 	  SSIDs); this requires driver support and can currently be used only
     83 	  with nl80211
     84 	* added support for WPS USBA out-of-band mechanism with USB Flash
     85 	  Drives (UFD) (CONFIG_WPS_UFD=y)
     86 	* driver_ndis: add PAE group address to the multicast address list to
     87 	  fix wired IEEE 802.1X authentication
     88 	* fixed IEEE 802.11r key derivation function to match with the standard
     89 	  (note: this breaks interoperability with previous version) [Bug 303]
     90 	* added better support for drivers that allow separate authentication
     91 	  and association commands (e.g., mac80211-based Linux drivers with
     92 	  nl80211; SME in wpa_supplicant); this allows over-the-air FT protocol
     93 	  to be used (IEEE 802.11r)
     94 	* fixed SHA-256 based key derivation function to match with the
     95 	  standard when using CCMP (for IEEE 802.11r and IEEE 802.11w)
     96 	  (note: this breaks interoperability with previous version) [Bug 307]
     97 	* use shared driver wrapper files with hostapd
     98 	* added AP mode functionality (CONFIG_AP=y) with mode=2 in the network
     99 	  block; this can be used for open and WPA2-Personal networks
    100 	  (optionally, with WPS); this links in parts of hostapd functionality
    101 	  into wpa_supplicant
    102 	* wpa_gui-qt4: added new Peers dialog to show information about peers
    103 	  (other devices, including APs and stations, etc. in the neighborhood)
    104 	* added support for WPS External Registrar functionality (configure APs
    105 	  and enroll new devices); can be used with wpa_gui-qt4 Peers dialog
    106 	  and wpa_cli commands wps_er_start, wps_er_stop, wps_er_pin,
    107 	  wps_er_pbc, wps_er_learn
    108 	  (this can also be used with a new 'none' driver wrapper if no
    109 	  wireless device or IEEE 802.1X on wired is needed)
    110 	* driver_nl80211: multiple updates to provide support for new Linux
    111 	  nl80211/mac80211 functionality
    112 	* updated management frame protection to use IEEE Std 802.11w-2009
    113 	* fixed number of small WPS issues and added workarounds to
    114 	  interoperate with common deployed broken implementations
    115 	* added support for NFC out-of-band mechanism with WPS
    116 	* driver_ndis: fixed wired IEEE 802.1X authentication with PAE group
    117 	  address frames
    118 	* added preliminary support for IEEE 802.11r RIC processing
    119 	* added support for specifying subset of enabled frequencies to scan
    120 	  (scan_freq option in the network configuration block); this can speed
    121 	  up scanning process considerably if it is known that only a small
    122 	  subset of channels is actually used in the network (this is currently
    123 	  supported only with -Dnl80211)
    124 	* added a workaround for race condition between receiving the
    125 	  association event and the following EAPOL-Key
    126 	* added background scan and roaming infrastructure to allow
    127 	  network-specific optimizations to be used to improve roaming within
    128 	  an ESS (same SSID)
    129 	* added new DBus interface (fi.w1.wpa_supplicant1)
    130 
    131 2009-01-06 - v0.6.7
    132 	* added support for Wi-Fi Protected Setup (WPS)
    133 	  (wpa_supplicant can now be configured to act as a WPS Enrollee to
    134 	  enroll credentials for a network using PIN and PBC methods; in
    135 	  addition, wpa_supplicant can act as a wireless WPS Registrar to
    136 	  configure an AP); WPS support can be enabled by adding CONFIG_WPS=y
    137 	  into .config and setting the runtime configuration variables in
    138 	  wpa_supplicant.conf (see WPS section in the example configuration
    139 	  file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to
    140 	  manage WPS negotiation; see README-WPS for more details
    141 	* added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
    142 	* added support for using driver_test over UDP socket
    143 	* fixed PEAPv0 Cryptobinding interoperability issue with Windows Server
    144 	  2008 NPS; optional cryptobinding is now enabled (again) by default
    145 	* fixed PSK editing in wpa_gui
    146 	* changed EAP-GPSK to use the IANA assigned EAP method type 51
    147 	* added a Windows installer that includes WinPcap and all the needed
    148 	  DLLs; in addition, it set up the registry automatically so that user
    149 	  will only need start wpa_gui to get prompted to start the wpasvc
    150 	  servide and add a new interface if needed through wpa_gui dialog
    151 	* updated management frame protection to use IEEE 802.11w/D7.0
    152 
    153 2008-11-23 - v0.6.6
    154 	* added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
    155 	  (can be used to simulate test SIM/USIM card with a known private key;
    156 	  enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
    157 	  and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
    158 	* added a new network configuration option, wpa_ptk_rekey, that can be
    159 	  used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
    160 	  against TKIP deficiencies
    161 	* added an optional mitigation mechanism for certain attacks against
    162 	  TKIP by delaying Michael MIC error reports by a random amount of time
    163 	  between 0 and 60 seconds; this can be enabled with a build option
    164 	  CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
    165 	* fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
    166 	  not bytes
    167 	* updated OpenSSL code for EAP-FAST to use an updated version of the
    168 	  session ticket overriding API that was included into the upstream
    169 	  OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
    170 	  needed with that version anymore)
    171 	* updated userspace MLME instructions to match with the current Linux
    172 	  mac80211 implementation; please also note that this can only be used
    173 	  with driver_nl80211.c (the old code from driver_wext.c was removed)
    174 	* added support (Linux only) for RoboSwitch chipsets (often found in
    175 	  consumer grade routers); driver interface 'roboswitch'
    176 	* fixed canceling of PMKSA caching when using drivers that generate
    177 	  RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
    178 	  about
    179 
    180 2008-11-01 - v0.6.5
    181 	* added support for SHA-256 as X.509 certificate digest when using the
    182 	  internal X.509/TLSv1 implementation
    183 	* updated management frame protection to use IEEE 802.11w/D6.0
    184 	* added support for using SHA256-based stronger key derivation for WPA2
    185 	  (IEEE 802.11w)
    186 	* fixed FT (IEEE 802.11r) authentication after a failed association to
    187 	  use correct FTIE
    188 	* added support for configuring Phase 2 (inner/tunneled) authentication
    189 	  method with wpa_gui-qt4
    190 
    191 2008-08-10 - v0.6.4
    192 	* added support for EAP Sequences in EAP-FAST Phase 2
    193 	* added support for using TNC with EAP-FAST
    194 	* added driver_ps3 for the PS3 Linux wireless driver
    195 	* added support for optional cryptobinding with PEAPv0
    196 	* fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
    197 	  allow fallback to full handshake if server rejects PAC-Opaque
    198 	* added fragmentation support for EAP-TNC
    199 	* added support for parsing PKCS #8 formatted private keys into the
    200 	  internal TLS implementation (both PKCS #1 RSA key and PKCS #8
    201 	  encapsulated RSA key can now be used)
    202 	* added option of using faster, but larger, routines in the internal
    203 	  LibTomMath (for internal TLS implementation) to speed up DH and RSA
    204 	  calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
    205 	* fixed race condition between disassociation event and group key
    206 	  handshake to avoid getting stuck in incorrect state [Bug 261]
    207 	* fixed opportunistic key caching (proactive_key_caching)
    208 
    209 2008-02-22 - v0.6.3
    210 	* removed 'nai' and 'eappsk' network configuration variables that were
    211 	  previously used for configuring user identity and key for EAP-PSK,
    212 	  EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
    213 	  replacement for 'nai' (if old configuration used a separate
    214 	  'identity' value, that would now be configured as
    215 	  'anonymous_identity'). 'password' field is now used as the
    216 	  replacement for 'eappsk' (it can also be set using hexstring to
    217 	  present random binary data)
    218 	* removed '-w' command line parameter (wait for interface to be added,
    219 	  if needed); cleaner way of handling this functionality is to use an
    220 	  external mechanism (e.g., hotplug scripts) that start wpa_supplicant
    221 	  when an interface is added
    222 	* updated FT support to use the latest draft, IEEE 802.11r/D9.0
    223 	* added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
    224 	  indicating when new scan results become available
    225 	* added new ctrl_iface command, BSS, to allow scan results to be
    226 	  fetched without hitting the message size limits (this command
    227 	  can be used to iterate through the scan results one BSS at the time)
    228 	* fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
    229 	  attributes in EAP-SIM Start/Response when using fast reauthentication
    230 	* fixed EAPOL not to end up in infinite loop when processing dynamic
    231 	  WEP keys with IEEE 802.1X
    232 	* fixed problems in getting NDIS events from WMI on Windows 2000
    233 
    234 2008-01-01 - v0.6.2
    235 	* added support for Makefile builds to include debug-log-to-a-file
    236 	  functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
    237 	* fixed EAP-SIM and EAP-AKA message parser to validate attribute
    238 	  lengths properly to avoid potential crash caused by invalid messages
    239 	* added data structure for storing allocated buffers (struct wpabuf);
    240 	  this does not affect wpa_supplicant usage, but many of the APIs
    241 	  changed and various interfaces (e.g., EAP) is not compatible with old
    242 	  versions
    243 	* added support for protecting EAP-AKA/Identity messages with
    244 	  AT_CHECKCODE (optional feature in RFC 4187)
    245 	* added support for protected result indication with AT_RESULT_IND for
    246 	  EAP-SIM and EAP-AKA (phase1="result_ind=1")
    247 	* added driver_wext workaround for race condition between scanning and
    248 	  association with drivers that take very long time to scan all
    249 	  channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
    250 	  using a longer hardcoded timeout for the scan if the driver supports
    251 	  notifications for scan completion (SIOCGIWSCAN event); this helps,
    252 	  e.g., in cases where wpa_supplicant and madwifi driver ended up in
    253 	  loop where the driver did not even try to associate
    254 	* stop EAPOL timer tick when no timers are in use in order to reduce
    255 	  power consumption (no need to wake up the process once per second)
    256 	  [Bug 237]
    257 	* added support for privilege separation (run only minimal part of
    258 	  wpa_supplicant functionality as root and rest as unprivileged,
    259 	  non-root process); see 'Privilege separation' in README for details;
    260 	  this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
    261 	  in .config
    262 	* changed scan results data structure to include all information
    263 	  elements to make it easier to support new IEs; old get_scan_result()
    264 	  driver_ops is still supported for backwards compatibility (results
    265 	  are converted internally to the new format), but all drivers should
    266 	  start using the new get_scan_results2() to make them more likely to
    267 	  work with new features
    268 	* Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
    269 	  application, i.e., it does not require Qt3Support anymore; Windows
    270 	  binary of wpa_gui.exe is now from this directory and only requires
    271 	  QtCore4.dll and QtGui4.dll libraries
    272 	* updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
    273 	  available as a separate package to make wpa_gui installation easier:
    274 	  http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
    275 	* added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
    276 	  only shared key/password authentication is supported in this version
    277 
    278 2007-11-24 - v0.6.1
    279 	* added support for configuring password as NtPasswordHash
    280 	  (16-byte MD4 hash of password) in hash:<32 hex digits> format
    281 	* added support for fallback from abbreviated TLS handshake to
    282 	  full handshake when using EAP-FAST (e.g., due to an expired
    283 	  PAC-Opaque)
    284 	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
    285 	  draft (draft-ietf-emu-eap-gpsk-07.txt)
    286 	* added support for drivers that take care of RSN 4-way handshake
    287 	  internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
    288 	  WPA_ALG_PMK in set_key)
    289 	* added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
    290 	  .config); this version supports only ap_scan=2 mode and allow the
    291 	  driver to take care of the 4-way handshake
    292 	* fixed a buffer overflow in parsing TSF from scan results when using
    293 	  driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
    294 	  [Bug 232]
    295 	* updated FT support to use the latest draft, IEEE 802.11r/D8.0
    296 	* fixed an integer overflow issue in the ASN.1 parser used by the
    297 	  (experimental) internal TLS implementation to avoid a potential
    298 	  buffer read overflow
    299 	* fixed a race condition with -W option (wait for a control interface
    300 	  monitor before starting) that could have caused the first messages to
    301 	  be lost
    302 	* added support for processing TNCC-TNCS-Messages to report
    303 	  recommendation (allow/none/isolate) when using TNC [Bug 243]
    304 
    305 2007-05-28 - v0.6.0
    306 	* added network configuration parameter 'frequency' for setting
    307 	  initial channel for IBSS (adhoc) networks
    308 	* added experimental IEEE 802.11r/D6.0 support
    309 	* updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
    310 	* updated EAP-PSK to use the IANA-allocated EAP type 47
    311 	* fixed EAP-PAX key derivation
    312 	* fixed EAP-PSK bit ordering of the Flags field
    313 	* fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
    314 	  tunnelled identity request (previously, the identifier from the outer
    315 	  method was used, not the tunnelled identifier which could be
    316 	  different)
    317 	* added support for fragmentation of outer TLS packets during Phase 2
    318 	  of EAP-PEAP/TTLS/FAST
    319 	* fixed EAP-TTLS AVP parser processing for too short AVP lengths
    320 	* added support for EAP-FAST authentication with inner methods that
    321 	  generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
    322 	  for PAC provisioning)
    323 	* added support for authenticated EAP-FAST provisioning
    324 	* added support for configuring maximum number of EAP-FAST PACs to
    325 	  store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
    326 	* added support for storing EAP-FAST PACs in binary format
    327 	  (fast_pac_format=binary in phase1 string)
    328 	* fixed dbus ctrl_iface to validate message interface before
    329 	  dispatching to avoid a possible segfault [Bug 190]
    330 	* fixed PeerKey key derivation to use the correct PRF label
    331 	* updated Windows binary build to link against OpenSSL 0.9.8d and
    332 	  added support for EAP-FAST
    333 	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
    334 	  draft (draft-ietf-emu-eap-gpsk-04.txt)
    335 	* fixed EAP-AKA Notification processing to allow Notification to be
    336 	  processed after AKA Challenge response has been sent
    337 	* updated to use IEEE 802.11w/D2.0 for management frame protection
    338 	  (still experimental)
    339 	* fixed EAP-TTLS implementation not to crash on use of freed memory
    340 	  if TLS library initialization fails
    341 	* added support for EAP-TNC (Trusted Network Connect)
    342 	  (this version implements the EAP-TNC method and EAP-TTLS changes
    343 	  needed to run two methods in sequence (IF-T) and the IF-IMC and
    344 	  IF-TNCCS interfaces from TNCC)
    345 
    346 2006-11-24 - v0.5.6
    347 	* added experimental, integrated TLSv1 client implementation with the
    348 	  needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
    349 	  setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
    350 	  .config); this can be useful, e.g., if the target system does not
    351 	  have a suitable TLS library and a minimal code size is required
    352 	  (total size of this internal TLS/crypto code is bit under 50 kB on
    353 	  x86 and the crypto code is shared by rest of the supplicant so some
    354 	  of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
    355 	* removed STAKey handshake since PeerKey handshake has replaced it in
    356 	  IEEE 802.11ma and there are no known deployments of STAKey
    357 	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
    358 	  draft (draft-ietf-emu-eap-gpsk-01.txt)
    359 	* added preliminary implementation of IEEE 802.11w/D1.0 (management
    360 	  frame protection)
    361 	  (Note: this requires driver support to work properly.)
    362 	  (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
    363 	* fixed Windows named pipes ctrl_iface to not stop listening for
    364 	  commands if client program opens a named pipe and closes it
    365 	  immediately without sending a command
    366 	* fixed USIM PIN status determination for the case that PIN is not
    367 	  needed (this allows EAP-AKA to be used with USIM cards that do not
    368 	  use PIN)
    369 	* added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
    370 	  be used with cards that do not support file selection based on
    371 	  partial AID
    372 	* added support for matching the subjectAltName of the authentication
    373 	  server certificate against multiple name components (e.g.,
    374 	  altsubject_match="DNS:server.example.com;DNS:server2.example.com")
    375 	* fixed EAP-SIM/AKA key derivation for re-authentication case (only
    376 	  affects IEEE 802.1X with dynamic WEP keys)
    377 	* changed ctrl_iface network configuration 'get' operations to not
    378 	  return password/key material; if these fields are requested, "*"
    379 	  will be returned if the password/key is set, but the value of the
    380 	  parameter is not exposed
    381 
    382 2006-08-27 - v0.5.5
    383 	* added support for building Windows version with UNICODE defined
    384 	  (wide-char functions)
    385 	* driver_ndis: fixed static WEP configuration to avoid race condition
    386 	  issues with some NDIS drivers between association and setting WEP
    387 	  keys
    388 	* driver_ndis: added validation for IELength value in scan results to
    389 	  avoid crashes when using buggy NDIS drivers [Bug 165]
    390 	* fixed Release|Win32 target in the Visual Studio project files
    391 	  (previously, only Debug|Win32 target was set properly)
    392 	* changed control interface API call wpa_ctrl_pending() to allow it to
    393 	  return -1 on error (e.g., connection lost); control interface clients
    394 	  will need to make sure that they verify that the value is indeed >0
    395 	  when determining whether there are pending messages
    396 	* added an alternative control interface backend for Windows targets:
    397 	  Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
    398 	  control interface mechanism for Windows builds (previously, UDP to
    399 	  localhost was used)
    400 	* changed ctrl_interface configuration for UNIX domain sockets:
    401 	  - deprecated ctrl_interface_group variable (it may be removed in
    402 	    future versions)
    403 	  - allow both directory and group be configured with ctrl_interface
    404 	    in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
    405 	  - ctrl_interface=/var/run/wpa_supplicant is still supported for the
    406 	    case when group is not changed
    407 	* added support for controlling more than one interface per process in
    408 	  Windows version
    409 	* added a workaround for a case where the AP is using unknown address
    410 	  (e.g., MAC address of the wired interface) as the source address for
    411 	  EAPOL-Key frames; previously, that source address was used as the
    412 	  destination for EAPOL-Key frames and in key derivation; now, BSSID is
    413 	  used even if the source address does not match with it
    414 	  (this resolves an interoperability issue with Thomson SpeedTouch 580)
    415 	* added a workaround for UDP-based control interface (which was used in
    416 	  Windows builds before this release) to prevent packets with forged
    417 	  addresses from being accepted as local control requests
    418 	* removed ndis_events.cpp and possibility of using external
    419 	  ndis_events.exe; C version (ndis_events.c) is fully functional and
    420 	  there is no desire to maintain two separate versions of this
    421 	  implementation
    422 	* ndis_events: Changed NDIS event notification design to use WMI to
    423 	  learn the adapter description through Win32_PnPEntity class; this
    424 	  should fix some cases where the adapter name was not recognized
    425 	  correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
    426 	  USB) [Bug 113]
    427 	* fixed selection of the first network in ap_scan=2 mode; previously,
    428 	  wpa_supplicant could get stuck in SCANNING state when only the first
    429 	  network for enabled (e.g., after 'wpa_cli select_network 0')
    430 	* winsvc: added support for configuring ctrl_interface parameters in
    431 	  registry (ctrl_interface string value in
    432 	  HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
    433 	  required to enable control interface (previously, this was hardcoded
    434 	  to be enabled)
    435 	* allow wpa_gui subdirectory to be built with both Qt3 and Qt4
    436 	* converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
    437 
    438 2006-06-20 - v0.5.4
    439 	* fixed build with CONFIG_STAKEY=y [Bug 143]
    440 	* added support for doing MLME (IEEE 802.11 management frame
    441 	  processing) in wpa_supplicant when using Devicescape IEEE 802.11
    442 	  stack (wireless-dev.git tree)
    443 	* added a new network block configuration option, fragment_size, to
    444 	  configure the maximum EAP fragment size
    445 	* driver_ndis: Disable WZC automatically for the selected interface to
    446 	  avoid conflicts with two programs trying to control the radio; WZC
    447 	  will be re-enabled (if it was enabled originally) when wpa_supplicant
    448 	  is terminated
    449 	* added an experimental TLSv1 client implementation
    450 	  (CONFIG_TLS=internal) that can be used instead of an external TLS
    451 	  library, e.g., to reduce total size requirement on systems that do
    452 	  not include any TLS library by default (this is not yet complete;
    453 	  basic functionality is there, but certificate validation is not yet
    454 	  included)
    455 	* added PeerKey handshake implementation for IEEE 802.11e
    456 	  direct link setup (DLS) to replace STAKey handshake
    457 	* fixed WPA PSK update through ctrl_iface for the case where the old
    458 	  PSK was derived from an ASCII passphrase and the new PSK is set as
    459 	  a raw PSK (hex string)
    460 	* added new configuration option for identifying which network block
    461 	  was used (id_str in wpa_supplicant.conf; included on
    462 	  WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
    463 	  variable in wpa_cli action scripts; in addition WPA_ID variable is
    464 	  set to the current unique identifier that wpa_supplicant assigned
    465 	  automatically for the network and that can be used with
    466 	  GET_NETWORK/SET_NETWORK ctrl_iface commands)
    467 	* wpa_cli action script is now called only when the connect/disconnect
    468 	  status changes or when associating with a different network
    469 	* fixed configuration parser not to remove CCMP from group cipher list
    470 	  if WPA-None (adhoc) is used (pairwise=NONE in that case)
    471 	* fixed integrated NDIS events processing not to hang the process due
    472 	  to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
    473 	* added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
    474 	  draft-clancy-emu-eap-shared-secret-00.txt)
    475 	* added Microsoft Visual Studio 2005 solution and project files for
    476 	  build wpa_supplicant for Windows (see vs2005 subdirectory)
    477 	* eloop_win: fixed unregistration of Windows events
    478 	* l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
    479 	  at the end of RSN pre-authentication and added unregistration of
    480 	  a Windows event to avoid getting eloop_win stuck with an invalid
    481 	  handle
    482 	* driver_ndis: added support for selecting AP based on BSSID
    483 	* added new environmental variable for wpa_cli action scripts:
    484 	  WPA_CTRL_DIR is the current control interface directory
    485 	* driver_ndis: added support for using NDISUIO instead of WinPcap for
    486 	  OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
    487 	  l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
    488 	  wpa_supplicant without requiring WinPcap; note that using NDISUIO
    489 	  requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
    490 	  only one application to open the device
    491 	* changed NDIS driver naming to only include device GUID, e.g.,
    492 	  {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
    493 	  specific \Device\NPF_ prefix before the GUID; the prefix is still
    494 	  allowed for backwards compatibility, but it is not required anymore
    495 	  when specifying the interface
    496 	* driver_ndis: re-initialize driver interface is the adapter is removed
    497 	  and re-inserted [Bug 159]
    498 	* driver_madwifi: fixed TKIP and CCMP sequence number configuration on
    499 	  big endian hosts [Bug 146]
    500 
    501 2006-04-27 - v0.5.3
    502 	* fixed EAP-GTC response to include correct user identity when run as
    503 	  phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
    504 	* driver_ndis: Fixed encryption mode configuration for unencrypted
    505 	  networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
    506 	  refused to associate with open networks) [Bug 106]
    507 	* driver_ndis: use BSSID OID polling to detect when IBSS network is
    508 	  formed even when ndis_events code is included since some NDIS drivers
    509 	  do not generate media connect events in IBSS mode
    510 	* config_winreg: allow global ctrl_interface parameter to be configured
    511 	  in Windows registry
    512 	* config_winreg: added support for saving configuration data into
    513 	  Windows registry
    514 	* added support for controlling network device operational state
    515 	  (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
    516 	  http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
    517 	  that can use this information)
    518 	* driver_wext: added support for WE-21 change to SSID configuration
    519 	* driver_wext: fixed privacy configuration for static WEP keys mode
    520 	  [Bug 140]
    521 	* added an optional driver_ops callback for MLME-SETPROTECTION.request
    522 	  primitive
    523 	* added support for EAP-SAKE (no EAP method number allocated yet, so
    524 	  this is using the same experimental type 255 as EAP-PSK)
    525 	* added support for dynamically loading EAP methods (.so files) instead
    526 	  of requiring them to be statically linked in; this is disabled by
    527 	  default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
    528 	  on how to use this)
    529 
    530 2006-03-19 - v0.5.2
    531 	* do not try to use USIM APDUs when initializing PC/SC for SIM card
    532 	  access for a network that has not enabled EAP-AKA
    533 	* fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
    534 	  v0.5.1 due to the new support for expanded EAP types)
    535 	* added support for generating EAP Expanded Nak
    536 	* try to fetch scan results once before requesting new scan when
    537 	  starting up in ap_scan=1 mode (this can speed up initial association
    538 	  a lot with, e.g., madwifi-ng driver)
    539 	* added support for receiving EAPOL frames from a Linux bridge
    540 	  interface (-bbr0 on command line)
    541 	* fixed EAPOL re-authentication for sessions that used PMKSA caching
    542 	* changed EAP method registration to use a dynamic list of methods
    543 	  instead of a static list generated at build time
    544 	* fixed PMKSA cache deinitialization not to use freed memory when
    545 	  removing PMKSA entries
    546 	* fixed a memory leak in EAP-TTLS re-authentication
    547 	* reject WPA/WPA2 message 3/4 if it does not include any valid
    548 	  WPA/RSN IE
    549 	* driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
    550 	  if the driver does not support SIOCSIWAUTH
    551 
    552 2006-01-29 - v0.5.1
    553 	* driver_test: added better support for multiple APs and STAs by using
    554 	  a directory with sockets that include MAC address for each device in
    555 	  the name (driver_param=test_dir=/tmp/test)
    556 	* added support for EAP expanded type (vendor specific EAP methods)
    557 	* added AP_SCAN command into ctrl_iface so that ap_scan configuration
    558 	  option can be changed if needed
    559 	* wpa_cli/wpa_gui: skip non-socket files in control directory when
    560 	  using UNIX domain sockets; this avoids selecting an incorrect
    561 	  interface (e.g., a PID file could be in this directory, even though
    562 	  use of this directory for something else than socket files is not
    563 	  recommended)
    564 	* fixed TLS library deinitialization after RSN pre-authentication not
    565 	  to disable TLS library for normal authentication
    566 	* driver_wext: Remove null-termination from SSID length if the driver
    567 	  used it; some Linux drivers do this and they were causing problems in
    568 	  wpa_supplicant not finding matching configuration block. This change
    569 	  would break a case where the SSID actually ends in '\0', but that is
    570 	  not likely to happen in real use.
    571 	* fixed PMKSA cache processing not to trigger deauthentication if the
    572 	  current PMKSA cache entry is replaced with a valid new entry
    573 	* fixed PC/SC initialization for ap_scan != 1 modes (this fixes
    574 	  EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
    575 	  ap_scan=2)
    576 
    577 2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
    578 	* added experimental STAKey handshake implementation for IEEE 802.11e
    579 	  direct link setup (DLS); note: this is disabled by default in both
    580 	  build and runtime configuration (can be enabled with CONFIG_STAKEY=y
    581 	  and stakey=1)
    582 	* fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
    583 	  decrypt AT_ENCR_DATA attributes correctly
    584 	* fixed EAP-AKA to allow resynchronization within the same session
    585 	* made code closer to ANSI C89 standard to make it easier to port to
    586 	  other C libraries and compilers
    587 	* started moving operating system or C library specific functions into
    588 	  wrapper functions defined in os.h and implemented in os_*.c to make
    589 	  code more portable
    590 	* wpa_supplicant can now be built with Microsoft Visual C++
    591 	  (e.g., with the freely available Toolkit 2003 version or Visual
    592 	  C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
    593 	  example makefile for nmake
    594 	* added support for using Windows registry for command line parameters
    595 	  (CONFIG_MAIN=main_winsvc) and configuration data
    596 	  (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
    597 	  contents; this version can be run both as a Windows service and as a
    598 	  normal application; 'wpasvc.exe app' to start as applicant,
    599 	  'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
    600 	  'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
    601 	  unregister a service
    602 	* made it possible to link ndis_events.exe functionality into
    603 	  wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
    604 	* added better support for multiple control interface backends
    605 	  (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
    606 	* fixed PC/SC code to use correct length for GSM AUTH command buffer
    607 	  and to not use pioRecvPci with SCardTransmit() calls; these were not
    608 	  causing visible problems with pcsc-lite, but Windows Winscard.dll
    609 	  refused the previously used parameters; this fixes EAP-SIM and
    610 	  EAP-AKA authentication using SIM/USIM card under Windows
    611 	* added new event loop implementation for Windows using
    612 	  WaitForMultipleObject() instead of select() in order to allow waiting
    613 	  for non-socket objects; this can be selected with
    614 	  CONFIG_ELOOP=eloop_win in .config
    615 	* added support for selecting l2_packet implementation in .config
    616 	  (CONFIG_L2_PACKET; following options are available now: linux, pcap,
    617 	  winpcap, freebsd, none)
    618 	* added new l2_packet implementation for WinPcap
    619 	  (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
    620 	  reduce latency in EAPOL receive processing from about 100 ms to about
    621 	  3 ms
    622 	* added support for EAP-FAST key derivation using other ciphers than
    623 	  RC4-128-SHA for authentication and AES128-SHA for provisioning
    624 	* added support for configuring CA certificate as DER file and as a
    625 	  configuration blob
    626 	* fixed private key configuration as configuration blob and added
    627 	  support for using PKCS#12 as a blob
    628 	* tls_gnutls: added support for using PKCS#12 files; added support for
    629 	  session resumption
    630 	* added support for loading trusted CA certificates from Windows
    631 	  certificate store: ca_cert="cert_store://<name>", where <name> is
    632 	  likely CA (Intermediate CA certificates) or ROOT (root certificates)
    633 	* added C version of ndis_events.cpp and made it possible to build this
    634 	  with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
    635 	  easily on cross-compilation builds
    636 	* added wpasvc.exe into Windows binary release; this is an alternative
    637 	  version of wpa_supplicant.exe with configuration backend using
    638 	  Windows registry and with the entry point designed to run as a
    639 	  Windows service
    640 	* integrated ndis_events.exe functionality into wpa_supplicant.exe and
    641 	  wpasvc.exe and removed this additional tool from the Windows binary
    642 	  release since it is not needed anymore
    643 	* load winscard.dll functions dynamically when building with MinGW
    644 	  since MinGW does not yet include winscard library
    645 
    646 2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
    647 	* l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
    648 	  and WinPcap to receive frames sent to PAE group address
    649 	* disable EAP state machine when IEEE 802.1X authentication is not used
    650 	  in order to get rid of bogus "EAP failed" messages
    651 	* fixed OpenSSL error reporting to go through all pending errors to
    652 	  avoid confusing reports of old errors being reported at later point
    653 	  during handshake
    654 	* fixed configuration file updating to not write empty variables
    655 	  (e.g., proto or key_mgmt) that the file parser would not accept
    656 	* fixed ADD_NETWORK ctrl_iface command to use the same default values
    657 	  for variables as empty network definitions read from config file
    658 	  would get
    659 	* fixed EAP state machine to not discard EAP-Failure messages in many
    660 	  cases (e.g., during TLS handshake)
    661 	* fixed a infinite loop in private key reading if the configured file
    662 	  cannot be parsed successfully
    663 	* driver_madwifi: added support for madwifi-ng
    664 	* wpa_gui: do not display password/PSK field contents
    665 	* wpa_gui: added CA certificate configuration
    666 	* driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
    667 	* driver_ndis: include Beacon IEs in AssocInfo in order to notice if
    668 	  the new AP is using different WPA/RSN IE
    669 	* use longer timeout for IEEE 802.11 association to avoid problems with
    670 	  drivers that may take more than five second to associate
    671 
    672 2005-10-27 - v0.4.6
    673 	* allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
    674 	  RSN IE, but WPA IE would match with wpa_supplicant configuration
    675 	* added support for named configuration blobs in order to avoid having
    676 	  to use file system for external files (e.g., certificates);
    677 	  variables can be set to "blob://<blob name>" instead of file path to
    678 	  use a named blob; supported fields: pac_file, client_cert,
    679 	  private_key
    680 	* fixed RSN pre-authentication (it was broken in the clean up of WPA
    681 	  state machine interface in v0.4.5)
    682 	* driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
    683 	  sure the driver configures broadcast decryption correctly
    684 	* added ca_path (and ca_path2) configuration variables that can be used
    685 	  to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
    686 	  system-wide trusted CA list
    687 	* added support for starting wpa_supplicant without a configuration
    688 	  file (-C argument must be used to set ctrl_interface parameter for
    689 	  this case; in addition, -p argument can be used to provide
    690 	  driver_param; these new arguments can also be used with a
    691 	  configuration to override the values from the configuration)
    692 	* added global control interface that can be optionally used for adding
    693 	  and removing network interfaces dynamically (-g command line argument
    694 	  for both wpa_supplicant and wpa_cli) without having to restart
    695 	  wpa_supplicant process
    696 	* wpa_gui:
    697 	  - try to save configuration whenever something is modified
    698 	  - added WEP key configuration
    699 	  - added possibility to edit the current network configuration
    700 	* driver_ndis: fixed driver polling not to increase frequency on each
    701 	  received EAPOL frame due to incorrectly cancelled timeout
    702 	* added simple configuration file examples (in examples subdirectory)
    703 	* fixed driver_wext.c to filter wireless events based on ifindex to
    704 	  avoid interfaces receiving events from other interfaces
    705 	* delay sending initial EAPOL-Start couple of seconds to speed up
    706 	  authentication for the most common case of Authenticator starting
    707 	  EAP authentication immediately after association
    708 
    709 2005-09-25 - v0.4.5
    710 	* added a workaround for clearing keys with ndiswrapper to allow
    711 	  roaming from WPA enabled AP to plaintext one
    712 	* added docbook documentation (doc/docbook) that can be used to
    713 	  generate, e.g., man pages
    714 	* l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
    715 	  PF_PACKET in order to prepare for network devices that do not use
    716 	  Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
    717 	* use receipt of EAPOL-Key frame as a lower layer success indication
    718 	  for EAP state machine to allow recovery from dropped EAP-Success
    719 	  frame
    720 	* cleaned up internal EAPOL frame processing by not including link
    721 	  layer (Ethernet) header during WPA and EAPOL/EAP processing; this
    722 	  header is added only when transmitted the frame; this makes it easier
    723 	  to use wpa_supplicant on link layers that use different header than
    724 	  Ethernet
    725 	* updated EAP-PSK to use draft 9 by default since this can now be
    726 	  tested with hostapd; removed support for draft 3, including
    727 	  server_nai configuration option from network blocks
    728 	* driver_wired: add PAE address to the multicast address list in order
    729 	  to be able to receive EAPOL frames with drivers that do not include
    730 	  these multicast addresses by default
    731 	* driver_wext: add support for WE-19
    732 	* added support for multiple configuration backends (CONFIG_BACKEND
    733 	  option); currently, only 'file' is supported (i.e., the format used
    734 	  in wpa_supplicant.conf)
    735 	* added support for updating configuration ('wpa_cli save_config');
    736 	  this is disabled by default and can be enabled with global
    737 	  update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
    738 	  and wpa_gui to store the configuration changes in a permanent store
    739 	* added GET_NETWORK ctrl_iface command
    740 	  (e.g., 'wpa_cli get_network 0 ssid')
    741 
    742 2005-08-21 - v0.4.4
    743 	* replaced OpenSSL patch for EAP-FAST support
    744 	  (openssl-tls-extensions.patch) with a more generic and correct
    745 	  patch (the new patch is not compatible with the previous one, so the
    746 	  OpenSSL library will need to be patched with the new patch in order
    747 	  to be able to build wpa_supplicant with EAP-FAST support)
    748 	* added support for using Windows certificate store (through CryptoAPI)
    749 	  for client certificate and private key operations (EAP-TLS)
    750 	  (see wpa_supplicant.conf for more information on how to configure
    751 	  this with private_key)
    752 	* ported wpa_gui to Windows
    753 	* added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
    754 	  built with the open source version of the Qt4 for Windows
    755 	* allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
    756 	  with drivers that do not support WPA
    757 	* ndis_events: fixed Windows 2000 support
    758 	* added support for enabling/disabling networks from the list of all
    759 	  configured networks ('wpa_cli enable_network <network id>' and
    760 	  'wpa_cli disable_network <network id>')
    761 	* added support for adding and removing network from the current
    762 	  configuration ('wpa_cli add_network' and 'wpa_cli remove_network
    763 	  <network id>'); added networks are disabled by default and they can
    764 	  be enabled with enable_network command once the configuration is done
    765 	  for the new network; note: configuration file is not yet updated, so
    766 	  these new networks are lost when wpa_supplicant is restarted
    767 	* added support for setting network configuration parameters through
    768 	  the control interface, for example:
    769 	  wpa_cli set_network 0 ssid "\"my network\""
    770 	* fixed parsing of strings that include both " and # within double
    771 	  quoted area (e.g., "start"#end")
    772 	* added EAP workaround for PEAP session resumption: allow outer,
    773 	  i.e., not tunneled, EAP-Success to terminate session since; this can
    774 	  be disabled with eap_workaround=0
    775 	  (this was allowed for PEAPv1 before, but now it is also allowed for
    776 	  PEAPv0 since at least one RADIUS authentication server seems to be
    777 	  doing this for PEAPv0, too)
    778 	* wpa_gui: added preliminary support for adding new networks to the
    779 	  wpa_supplicant configuration (double click on the scan results to
    780 	  open network configuration)
    781 
    782 2005-06-26 - v0.4.3
    783 	* removed interface for external EAPOL/EAP supplicant (e.g.,
    784 	  Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
    785 	  anymore and is unlikely to be used by anyone
    786 	* driver_ndis: fixed WinPcap 3.0 support
    787 	* fixed build with CONFIG_DNET_PCAP=y on Linux
    788 	* l2_packet: moved different implementations into separate files
    789 	  (l2_packet_*.c)
    790 
    791 2005-06-12 - v0.4.2
    792 	* driver_ipw: updated driver structures to match with ipw2200-1.0.4
    793 	  (note: ipw2100-1.1.0 is likely to require an update to work with
    794 	  this)
    795 	* added support for using ap_scan=2 mode with multiple network blocks;
    796 	  wpa_supplicant will go through the networks one by one until the
    797 	  driver reports a successful association; this uses the same order for
    798 	  networks as scan_ssid=1 scans, i.e., the priority field is ignored
    799 	  and the network block order in the file is used instead
    800 	* fixed a potential issue in RSN pre-authentication ending up using
    801 	  freed memory if pre-authentication times out
    802 	* added support for matching alternative subject name extensions of the
    803 	  authentication server certificate; new configuration variables
    804 	  altsubject_match and altsubject_match2
    805 	* driver_ndis: added support for IEEE 802.1X authentication with wired
    806 	  NDIS drivers
    807 	* added support for querying private key password (EAP-TLS) through the
    808 	  control interface (wpa_cli/wpa_gui) if one is not included in the
    809 	  configuration file
    810 	* driver_broadcom: fixed couple of memory leaks in scan result
    811 	  processing
    812 	* EAP-PAX is now registered as EAP type 46
    813 	* fixed EAP-PAX MAC calculation
    814 	* fixed EAP-PAX CK and ICK key derivation
    815 	* added support for using password with EAP-PAX (as an alternative to
    816 	  entering key with eappsk); SHA-1 hash of the password will be used as
    817 	  the key in this case
    818 	* added support for arbitrary driver interface parameters through the
    819 	  configuration file with a new driver_param field; this adds a new
    820 	  driver_ops function set_param()
    821 	* added possibility to override l2_packet module with driver interface
    822 	  API (new send_eapol handler); this can be used to implement driver
    823 	  specific TX/RX functions for EAPOL frames
    824 	* fixed ctrl_interface_group processing for the case where gid is
    825 	  entered as a number, not group name
    826 	* driver_test: added support for testing hostapd with wpa_supplicant
    827 	  by using test driver interface without any kernel drivers or network
    828 	  cards
    829 
    830 2005-05-22 - v0.4.1
    831 	* driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
    832 	  packets to be encrypted; this was apparently broken by the changed
    833 	  ioctl order in v0.4.0
    834 	* driver_madwifi: added preliminary support for compiling against 'BSD'
    835 	  branch of madwifi CVS tree
    836 	* added support for EAP-MSCHAPv2 password retries within the same EAP
    837 	  authentication session
    838 	* added support for password changes with EAP-MSCHAPv2 (used when the
    839 	  password has expired)
    840 	* added support for reading additional certificates from PKCS#12 files
    841 	  and adding them to the certificate chain
    842 	* fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
    843 	  were used
    844 	* fixed a possible double free in EAP-TTLS fast-reauthentication when
    845 	  identity or password is entered through control interface
    846 	* display EAP Notification messages to user through control interface
    847 	  with "CTRL-EVENT-EAP-NOTIFICATION" prefix
    848 	* added GUI version of wpa_cli, wpa_gui; this is not build
    849 	  automatically with 'make'; use 'make wpa_gui' to build (this requires
    850 	  Qt development tools)
    851 	* added 'disconnect' command to control interface for setting
    852 	  wpa_supplicant in state where it will not associate before
    853 	  'reassociate' command has been used
    854 	* added support for selecting a network from the list of all configured
    855 	  networks ('wpa_cli select_network <network id>'; this disabled all
    856 	  other networks; to re-enable, 'wpa_cli select_network any')
    857 	* added support for getting scan results through control interface
    858 	* added EAP workaround for PEAPv1 session resumption: allow outer,
    859 	  i.e., not tunneled, EAP-Success to terminate session since; this can
    860 	  be disabled with eap_workaround=0
    861 
    862 2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
    863 	* added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
    864 	  used to reduce the size of the wpa_supplicant considerably if
    865 	  debugging code is not needed
    866 	* fixed EAPOL-Key validation to drop packets with invalid Key Data
    867 	  Length; such frames could have crashed wpa_supplicant due to buffer
    868 	  overflow
    869 	* added support for wired authentication (IEEE 802.1X on wired
    870 	  Ethernet); driver interface 'wired'
    871 	* obsoleted set_wpa() handler in the driver interface API (it can be
    872 	  replaced by moving enable/disable functionality into init()/deinit())
    873 	  (calls to set_wpa() are still present for backwards compatibility,
    874 	  but they may be removed in the future)
    875 	* driver_madwifi: fixed association in plaintext mode
    876 	* modified the EAP workaround that accepts EAP-Success with incorrect
    877 	  Identifier to be even less strict about verification in order to
    878 	  interoperate with some authentication servers
    879 	* added support for sending TLS alerts
    880 	* added support for 'any' SSID wildcard; if ssid is not configured or
    881 	  is set to an empty string, any SSID will be accepted for non-WPA AP
    882 	* added support for asking PIN (for SIM) from frontends (e.g.,
    883 	  wpa_cli); if a PIN is needed, but not included in the configuration
    884 	  file, a control interface request is sent and EAP processing is
    885 	  delayed until the PIN is available
    886 	* added support for using external devices (e.g., a smartcard) for
    887 	  private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
    888 	  new wpa_supplicant.conf variables:
    889 	  - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
    890 	  - network: engine, engine_id, key_id
    891 	* added experimental support for EAP-PAX
    892 	* added monitor mode for wpa_cli (-a<path to a program to run>) that
    893 	  allows external commands (e.g., shell scripts) to be run based on
    894 	  wpa_supplicant events, e.g., when authentication has been completed
    895 	  and data connection is ready; other related wpa_cli arguments:
    896 	  -B (run in background), -P (write PID file); wpa_supplicant has a new
    897 	  command line argument (-W) that can be used to make it wait until a
    898 	  control interface command is received in order to avoid missing
    899 	  events
    900 	* added support for opportunistic WPA2 PMKSA key caching (disabled by
    901 	  default, can be enabled with proactive_key_caching=1)
    902 	* fixed RSN IE in 4-Way Handshake message 2/4 for the case where
    903 	  Authenticator rejects PMKSA caching attempt and the driver is not
    904 	  using assoc_info events
    905 	* added -P<pid file> argument for wpa_supplicant to write the current
    906 	  process id into a file
    907 
    908 2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
    909 	* added new phase1 option parameter, include_tls_length=1, to force
    910 	  wpa_supplicant to add TLS Message Length field to all TLS messages
    911 	  even if the packet is not fragmented; this may be needed with some
    912 	  authentication servers
    913 	* fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
    914 	  using drivers that take care of AP selection (e.g., when using
    915 	  ap_scan=2)
    916 	* fixed reprocessing of pending request after ctrl_iface requests for
    917 	  identity/password/otp
    918 	* fixed ctrl_iface requests for identity/password/otp in Phase 2 of
    919 	  EAP-PEAP and EAP-TTLS
    920 	* all drivers using driver_wext: set interface up and select Managed
    921 	  mode when starting wpa_supplicant; set interface down when exiting
    922 	* renamed driver_ipw2100.c to driver_ipw.c since it now supports both
    923 	  ipw2100 and ipw2200; please note that this also changed the
    924 	  configuration variable in .config to CONFIG_DRIVER_IPW
    925 
    926 2005-01-24 - v0.3.6
    927 	* fixed a busy loop introduced in v0.3.5 for scan result processing
    928 	  when no matching AP is found
    929 
    930 2005-01-23 - v0.3.5
    931 	* added a workaround for an interoperability issue with a Cisco AP
    932 	  when using WPA2-PSK
    933 	* fixed non-WPA IEEE 802.1X to use the same authentication timeout as
    934 	  WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
    935 	  retransmission of dropped frames)
    936 	* fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
    937 	  (e.g., segfault when processing EAPOL-Key frames)
    938 	* fixed EAP workaround and fast reauthentication configuration for
    939 	  RSN pre-authentication; previously these were disabled and
    940 	  pre-authentication would fail if the used authentication server
    941 	  requires EAP workarounds
    942 	* added support for blacklisting APs that fail or timeout
    943 	  authentication in ap_scan=1 mode so that all APs are tried in cases
    944 	  where the ones with strongest signal level are failing authentication
    945 	* fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
    946 	  authentication attempt
    947 	* allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
    948 	  in the previous authentication (previously, only Phase 1 success was
    949 	  verified)
    950 
    951 2005-01-09 - v0.3.4
    952 	* added preliminary support for IBSS (ad-hoc) mode configuration
    953 	  (mode=1 in network block); this included a new key_mgmt mode
    954 	  WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
    955 	  key management; see wpa_supplicant.conf for more details and an
    956 	  example on how to configure this (note: this is currently implemented
    957 	  only for driver_hostapd.c, but the changes should be trivial to add
    958 	  in associate() handler for other drivers, too (assuming the driver
    959 	  supports WPA-None)
    960 	* added preliminary port for native Windows (i.e., no cygwin) using
    961 	  mingw
    962 
    963 2005-01-02 - v0.3.3
    964 	* added optional support for GNU Readline and History Libraries for
    965 	  wpa_cli (CONFIG_READLINE)
    966 	* cleaned up EAP state machine <-> method interface and number of
    967 	  small problems with error case processing not terminating on
    968 	  EAP-Failure but waiting for timeout
    969 	* added couple of workarounds for interoperability issues with a
    970 	  Cisco AP when using WPA2
    971 	* added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
    972 	  Note: This requires a patch for openssl to add support for TLS
    973 	  extensions and number of workarounds for operations without
    974 	  certificates. Proof of concept type of experimental patch is
    975 	  included in openssl-tls-extensions.patch.
    976 
    977 2004-12-19 - v0.3.2
    978 	* fixed private key loading for cases where passphrase is not set
    979 	* fixed Windows/cygwin L2 packet handler freeing; previous version
    980 	  could cause a segfault when RSN pre-authentication was completed
    981 	* added support for PMKSA caching with drivers that generate RSN IEs
    982 	  (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
    983 	  but similar code can be easily added to driver_ndiswrapper.c once
    984 	  ndiswrapper gets full support for RSN PMKSA caching
    985 	* improved recovery from PMKID mismatches by requesting full EAP
    986 	  authentication in case of failed PMKSA caching attempt
    987 	* driver_ndis: added support for NDIS NdisMIncidateStatus() events
    988 	  (this requires that ndis_events is ran while wpa_supplicant is
    989 	  running)
    990 	* driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
    991 	* added support for driver interfaces to replace the interface name
    992 	  based on driver/OS specific mapping, e.g., in case of driver_ndis,
    993 	  this allows the beginning of the adapter description to be used as
    994 	  the interface name
    995 	* added support for CR+LF (Windows-style) line ends in configuration
    996 	  file
    997 	* driver_ndis: enable radio before starting scanning, disable radio
    998 	  when exiting
    999 	* modified association event handler to set portEnabled = FALSE before
   1000 	  clearing port Valid in order to reset EAP state machine and avoid
   1001 	  problems with new authentication getting ignored because of state
   1002 	  machines ending up in AUTHENTICATED/SUCCESS state based on old
   1003 	  information
   1004 	* added support for driver events to add PMKID candidates in order to
   1005 	  allow drivers to give priority to most likely roaming candidates
   1006 	* driver_hostap: moved PrivacyInvoked configuration to associate()
   1007 	  function so that this will not be set for plaintext connections
   1008 	* added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
   1009 	  interface can distinguish plaintext and IEEE 802.1X (no WPA)
   1010 	  authentication
   1011 	* fixed static WEP key configuration to use broadcast/default type for
   1012 	  all keys (previously, the default TX key was configured as pairwise/
   1013 	  unicast key)
   1014 	* driver_ndis: added legacy WPA capability detection for non-WPA2
   1015 	  drivers
   1016 	* added support for setting static WEP keys for IEEE 802.1X without
   1017 	  dynamic WEP keying (eapol_flags=0)
   1018 
   1019 2004-12-12 - v0.3.1
   1020 	* added support for reading PKCS#12 (PFX) files (as a replacement for
   1021 	  PEM/DER) to get certificate and private key (CONFIG_PKCS12)
   1022 	* fixed compilation with CONFIG_PCSC=y
   1023 	* added new ap_scan mode, ap_scan=2, for drivers that take care of
   1024 	  association, but need to be configured with security policy and SSID,
   1025 	  e.g., ndiswrapper and NDIS driver; this mode should allow such
   1026 	  drivers to work with hidden SSIDs and optimized roaming; when
   1027 	  ap_scan=2 is used, only the first network block in the configuration
   1028 	  file is used and this configuration should have explicit security
   1029 	  policy (i.e., only one option in the lists) for key_mgmt, pairwise,
   1030 	  group, proto variables
   1031 	* added experimental port of wpa_supplicant for Windows
   1032 	  - driver_ndis.c driver interface (NDIS OIDs)
   1033 	  - currently, this requires cygwin and WinPcap
   1034 	  - small utility, win_if_list, can be used to get interface name
   1035 	* control interface can now be removed at build time; add
   1036 	  CONFIG_CTRL_IFACE=y to .config to maintain old functionality
   1037 	* optional Xsupplicant interface can now be removed at build time;
   1038 	  (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
   1039 	* added auth_alg to driver interface associate() parameters to make it
   1040 	  easier for drivers to configure authentication algorithm as part of
   1041 	  the association
   1042 
   1043 2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
   1044 	* driver_broadcom: added new driver interface for Broadcom wl.o driver
   1045 	  (a generic driver for Broadcom IEEE 802.11a/g cards)
   1046 	* wpa_cli: fixed parsing of -p <path> command line argument
   1047 	* PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
   1048 	  ACK, not tunneled EAP-Success (of which only the first byte was
   1049 	  actually send due to a bug in previous code); this seems to
   1050 	  interoperate with most RADIUS servers that implements PEAPv1
   1051 	* PEAPv1: added support for terminating PEAP authentication on tunneled
   1052 	  EAP-Success message; this can be configured by adding
   1053 	  peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
   1054 	  (some RADIUS servers require this whereas others require a tunneled
   1055 	  reply
   1056 	* PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
   1057 	  the old label for key derivation; previously, the default was 1,
   1058 	  but it looks like most existing PEAPv1 implementations use the old
   1059 	  label which is thus more suitable default option
   1060 	* added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
   1061 	* fixed parsing of wep_tx_keyidx
   1062 	* added support for configuring list of allowed Phase 2 EAP types
   1063 	  (for both EAP-PEAP and EAP-TTLS) instead of only one type
   1064 	* added support for configuring IEEE 802.11 authentication algorithm
   1065 	  (auth_alg; mainly for using Shared Key authentication with static
   1066 	  WEP keys)
   1067 	* added support for EAP-AKA (with UMTS SIM)
   1068 	* fixed couple of errors in PCSC handling that could have caused
   1069 	  random-looking errors for EAP-SIM
   1070 	* added support for EAP-SIM pseudonyms and fast re-authentication
   1071 	* added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
   1072 	  session resumption)
   1073 	* added support for EAP-SIM with two challanges
   1074 	  (phase1="sim_min_num_chal=3" can be used to require three challenges)
   1075 	* added support for configuring DH/DSA parameters for an ephemeral DH
   1076 	  key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
   1077 	  dh_file and dh_file2 (phase 2); this adds support for using DSA keys
   1078 	  and optional DH key exchange to achieve forward secracy with RSA keys
   1079 	* added support for matching subject of the authentication server
   1080 	  certificate with a substring when using EAP-TLS/PEAP/TTLS; new
   1081 	  configuration variables subject_match and subject_match2
   1082 	* changed SSID configuration in driver_wext.c (used by many driver
   1083 	  interfaces) to use ssid_len+1 as the length for SSID since some Linux
   1084 	  drivers expect this
   1085 	* fixed couple of unaligned reads in scan result parsing to fix WPA
   1086 	  connection on some platforms (e.g., ARM)
   1087 	* added driver interface for Intel ipw2100 driver
   1088 	* added support for LEAP with WPA
   1089 	* added support for larger scan results report (old limit was 4 kB of
   1090 	  data, i.e., about 35 or so APs) when using Linux wireless extensions
   1091 	  v17 or newer
   1092 	* fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
   1093 	  only if there is a PMKSA cache entry for the current AP
   1094 	* fixed error handling for case where reading of scan results fails:
   1095 	  must schedule a new scan or wpa_supplicant will remain waiting
   1096 	  forever
   1097 	* changed debug output to remove shared password/key material by
   1098 	  default; all key information can be included with -K command line
   1099 	  argument to match the previous behavior
   1100 	* added support for timestamping debug log messages (disabled by
   1101 	  default, can be enabled with -t command line argument)
   1102 	* set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
   1103 	  if keys are not configured to be used; this fixes IEEE 802.1X mode
   1104 	  with drivers that use this information to configure whether Privacy
   1105 	  bit can be in Beacon frames (e.g., ndiswrapper)
   1106 	* avoid clearing driver keys if no keys have been configured since last
   1107 	  key clear request; this seems to improve reliability of group key
   1108 	  handshake for ndiswrapper & NDIS driver which seems to be suffering
   1109 	  of some kind of timing issue when the keys are cleared again after
   1110 	  association
   1111 	* changed driver interface API:
   1112 	  - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
   1113 	    version is being used (now, this is set to 2; previously, it was
   1114 	    not defined)
   1115 	  - pass pointer to private data structure to all calls
   1116 	  - the new API is not backwards compatible; all in-tree driver
   1117 	    interfaces has been converted to the new API
   1118 	* added support for controlling multiple interfaces (radios) per
   1119 	  wpa_supplicant process; each interface needs to be listed on the
   1120 	  command line (-c, -i, -D arguments) with -N as a separator
   1121 	  (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
   1122 	* added a workaround for EAP servers that incorrectly use same Id for
   1123 	  sequential EAP packets
   1124 	* changed libpcap/libdnet configuration to use .config variable,
   1125 	  CONFIG_DNET_PCAP, instead of requiring Makefile modification
   1126 	* improved downgrade attack detection in IE verification of msg 3/4:
   1127 	  verify both WPA and RSN IEs, if present, not only the selected one;
   1128 	  reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
   1129 	  Probe Response frame, and RSN is enabled in wpa_supplicant
   1130 	  configuration
   1131 	* fixed WPA msg 3/4 processing to allow Key Data field contain other
   1132 	  IEs than just one WPA IE
   1133 	* added support for FreeBSD and driver interface for the BSD net80211
   1134 	  layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
   1135 	  required kernel mods have not yet been committed
   1136 	* made EAP workarounds configurable; enabled by default, can be
   1137 	  disabled with network block option eap_workaround=0
   1138 
   1139 2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
   1140 	* resolved couple of interoperability issues with EAP-PEAPv1 and
   1141 	  Phase 2 (inner EAP) fragment reassembly
   1142 	* driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
   1143 	  AP is using non-zero key index for the unicast key and key index zero
   1144 	  for the broadcast key
   1145 	* driver_hostap: fixed IEEE 802.1X WEP key updates and
   1146 	  re-authentication by allowing unencrypted EAPOL frames when not using
   1147 	  WPA
   1148 	* added a new driver interface, 'wext', which uses only standard,
   1149 	  driver independent functionality in Linux wireless extensions;
   1150 	  currently, this can be used only for non-WPA IEEE 802.1X mode, but
   1151 	  eventually, this is to be extended to support full WPA/WPA2 once
   1152 	  Linux wireless extensions get support for this
   1153 	* added support for mode in which the driver is responsible for AP
   1154 	  scanning and selection; this is disabled by default and can be
   1155 	  enabled with global ap_scan=0 variable in wpa_supplicant.conf;
   1156 	  this mode can be used, e.g., with generic 'wext' driver interface to
   1157 	  use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
   1158 	  supporting wireless extensions.
   1159 	* driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
   1160 	  operation with an AP that does not include SSID in the Beacon frames)
   1161 	* added support for new EAP authentication methods:
   1162 	  EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
   1163 	* added support for asking one-time-passwords from frontends (e.g.,
   1164 	  wpa_cli); this 'otp' command works otherwise like 'password' command,
   1165 	  but the password is used only once and the frontend will be asked for
   1166 	  a new password whenever a request from authenticator requires a
   1167 	  password; this can be used with both EAP-OTP and EAP-GTC
   1168 	* changed wpa_cli to automatically re-establish connection so that it
   1169 	  does not need to be re-started when wpa_supplicant is terminated and
   1170 	  started again
   1171 	* improved user data (identity/password/otp) requests through
   1172 	  frontends: process pending EAPOL packets after getting new
   1173 	  information so that full authentication does not need to be
   1174 	  restarted; in addition, send pending requests again whenever a new
   1175 	  frontend is attached
   1176 	* changed control frontends to use a new directory for socket files to
   1177 	  make it easier for wpa_cli to automatically select between interfaces
   1178 	  and to provide access control for the control interface;
   1179 	  wpa_supplicant.conf: ctrl_interface is now a path
   1180 	  (/var/run/wpa_supplicant is the recommended path) and
   1181 	  ctrl_interface_group can be used to select which group gets access to
   1182 	  the control interface;
   1183 	  wpa_cli: by default, try to connect to the first interface available
   1184 	  in /var/run/wpa_supplicant; this path can be overriden with -p option
   1185 	  and an interface can be selected with -i option (i.e., in most common
   1186 	  cases, wpa_cli does not need to get any arguments)
   1187 	* added support for LEAP
   1188 	* added driver interface for Linux ndiswrapper
   1189 	* added priority option for network blocks in the configuration file;
   1190 	  this allows networks to be grouped based on priority (the scan
   1191 	  results are searched for matches with network blocks in this order)
   1192 
   1193 2004-06-20 - v0.2.3
   1194 	* sort scan results to improve AP selection
   1195 	* fixed control interface socket removal for some error cases
   1196 	* improved scan requesting and authentication timeout
   1197 	* small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
   1198 	  TLS processing
   1199 	* PEAP version can now be forced with phase1="peapver=<ver>"
   1200 	  (mostly for testing; by default, the highest version supported by
   1201 	  both the Supplicant and Authentication Server is selected
   1202 	  automatically)
   1203 	* added support for madwifi driver (Atheros ar521x)
   1204 	* added a workaround for cases where AP sets Install Tx/Rx bit for
   1205 	  WPA Group Key messages when pairwise keys are used (without this,
   1206 	  the Group Key would be used for Tx and the AP would drop frames
   1207 	  from the station)
   1208 	* added GSM SIM/USIM interface for GSM authentication algorithm for
   1209 	  EAP-SIM; this requires pcsc-lite
   1210 	* added support for ATMEL AT76C5XXx driver
   1211 	* fixed IEEE 802.1X WEP key derivation in the case where Authenticator
   1212 	  does not include key data in the EAPOL-Key frame (i.e., part of
   1213 	  EAP keying material is used as data encryption key)
   1214 	* added support for using plaintext and static WEP networks
   1215 	  (key_mgmt=NONE)
   1216 
   1217 2004-05-31 - v0.2.2
   1218 	* added support for new EAP authentication methods:
   1219 	  EAP-TTLS/EAP-MD5-Challenge
   1220 	  EAP-TTLS/EAP-GTC
   1221 	  EAP-TTLS/EAP-MSCHAPv2
   1222 	  EAP-TTLS/EAP-TLS
   1223 	  EAP-TTLS/MSCHAPv2
   1224 	  EAP-TTLS/MSCHAP
   1225 	  EAP-TTLS/PAP
   1226 	  EAP-TTLS/CHAP
   1227 	  EAP-PEAP/TLS
   1228 	  EAP-PEAP/GTC
   1229 	  EAP-PEAP/MD5-Challenge
   1230 	  EAP-GTC
   1231 	  EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
   1232 	* added support for anonymous identity (to be used when identity is
   1233 	  sent in plaintext; real identity will be used within TLS protected
   1234 	  tunnel (e.g., with EAP-TTLS)
   1235 	* added event messages from wpa_supplicant to frontends, e.g., wpa_cli
   1236 	* added support for requesting identity and password information using
   1237 	  control interface; in other words, the password for EAP-PEAP or
   1238 	  EAP-TTLS does not need to be included in the configuration file since
   1239 	  a frontand (e.g., wpa_cli) can ask it from the user
   1240 	* improved RSN pre-authentication to use a candidate list and process
   1241 	  all candidates from each scan; not only one per scan
   1242 	* fixed RSN IE and WPA IE capabilities field parsing
   1243 	* ignore Tx bit in GTK IE when Pairwise keys are used
   1244 	* avoid making new scan requests during IEEE 802.1X negotiation
   1245 	* use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
   1246 	  with TLS support (this replaces the included implementation with
   1247 	  library code to save about 8 kB since the library code is needed
   1248 	  anyway for TLS)
   1249 	* fixed WPA-PSK only mode when compiled without IEEE 802.1X support
   1250 	  (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
   1251 
   1252 2004-05-06 - v0.2.1
   1253 	* added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
   1254 	  Supplicant
   1255 	  - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
   1256 	  - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
   1257 	  - EAP-MD5 (cannot be used with WPA-RADIUS)
   1258 	    [draft-ietf-eap-rfc2284bis-09.txt]
   1259 	  - EAP-TLS [RFC 2716]
   1260 	  - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
   1261 	  - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
   1262 	    [draft-kamath-pppext-eap-mschapv2-00.txt]
   1263 	    (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
   1264 	    default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
   1265 	  - new configuration file options: eap, identity, password, ca_cert,
   1266 	    client_cert, privatekey, private_key_passwd
   1267 	  - Xsupplicant is not required anymore, but it can be used by
   1268 	    disabling the internal IEEE 802.1X Supplicant with -e command line
   1269 	    option
   1270 	  - this code is not included in the default build; Makefile need to
   1271 	    be edited for this (uncomment lines for selected functionality)
   1272 	  - EAP-TLS and EAP-PEAP require openssl libraries
   1273 	* use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
   1274 	* added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
   1275 	  (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
   1276 	   EAPOL-Key frames instead of WPA key handshakes)
   1277 	* added support for IEEE 802.11i/RSN (WPA2)
   1278 	  - improved PTK Key Handshake
   1279 	  - PMKSA caching, pre-authentication
   1280 	* fixed wpa_supplicant to ignore possible extra data after WPA
   1281 	  EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
   1282 	  TPTK' error from message 3 of 4-Way Handshake in case the AP
   1283 	  includes extra data after the EAPOL-Key)
   1284 	* added interface for external programs (frontends) to control
   1285 	  wpa_supplicant
   1286 	  - CLI example (wpa_cli) with interactive mode and command line
   1287 	    mode
   1288 	  - replaced SIGUSR1 status/statistics with the new control interface
   1289 	* made some feature compile time configurable
   1290 	  - .config file for make
   1291 	  - driver interfaces (hostap, hermes, ..)
   1292 	  - EAPOL/EAP functions
   1293 
   1294 2004-02-15 - v0.2.0
   1295 	* Initial version of wpa_supplicant
   1296
