+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+                       59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) 19yy  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) 19yy name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989

+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+ChangeLog for wpa_supplicant
+
+2005-02-13 - v0.3.8
+	* fixed EAPOL-Key validation to drop packets with invalid Key Data
+	  Length; such frames could have crashed wpa_supplicant due to buffer
+	  overflow
+
+2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
+	* added new phase1 option parameter, include_tls_length=1, to force
+	  wpa_supplicant to add TLS Message Length field to all TLS messages
+	  even if the packet is not fragmented; this may be needed with some
+	  authentication servers
+	* fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
+	  using drivers that take care of AP selection (e.g., when using
+	  ap_scan=2)
+	* fixed reprocessing of pending request after ctrl_iface requests for
+	  identity/password/otp
+	* fixed ctrl_iface requests for identity/password/otp in Phase 2 of
+	  EAP-PEAP and EAP-TTLS
+	* all drivers using driver_wext: set interface up and select Managed
+	  mode when starting wpa_supplicant; set interface down when exiting
+	* renamed driver_ipw2100.c to driver_ipw.c since it now supports both
+	  ipw2100 and ipw2200; please note that this also changed the
+	  configuration variable in .config to CONFIG_DRIVER_IPW
+
+2005-01-24 - v0.3.6
+	* fixed a busy loop introduced in v0.3.5 for scan result processing
+	  when no matching AP is found
+
+2005-01-23 - v0.3.5
+	* added a workaround for an interoperability issue with a Cisco AP
+	  when using WPA2-PSK
+	* fixed non-WPA IEEE 802.1X to use the same authentication timeout as
+	  WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
+	  retransmission of dropped frames)
+	* fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
+	  (e.g., segfault when processing EAPOL-Key frames)
+	* fixed EAP workaround and fast reauthentication configuration for
+	  RSN pre-authentication; previously these were disabled and
+	  pre-authentication would fail if the used authentication server
+	  requires EAP workarounds
+	* added support for blacklisting APs that fail or timeout
+	  authentication in ap_scan=1 mode so that all APs are tried in cases
+	  where the ones with strongest signal level are failing authentication
+	* fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
+	  authentication attempt
+	* allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
+	  in the previous authentication (previously, only Phase 1 success was
+	  verified)
+
+2005-01-09 - v0.3.4
+	* added preliminary support for IBSS (ad-hoc) mode configuration
+	  (mode=1 in network block); this included a new key_mgmt mode
+	  WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
+	  key management; see wpa_supplicant.conf for more details and an
+	  example on how to configure this (note: this is currently implemented
+	  only for driver_hostapd.c, but the changes should be trivial to add
+	  in associate() handler for other drivers, too (assuming the driver
+	  supports WPA-None)
+	* added preliminary port for native Windows (i.e., no cygwin) using
+	  mingw
+
+2005-01-02 - v0.3.3
+	* added optional support for GNU Readline and History Libraries for
+	  wpa_cli (CONFIG_READLINE)
+	* cleaned up EAP state machine <-> method interface and number of
+	  small problems with error case processing not terminating on
+	  EAP-Failure but waiting for timeout
+	* added couple of workarounds for interoperability issues with a
+	  Cisco AP when using WPA2
+	* added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
+	  Note: This requires a patch for openssl to add support for TLS
+	  extensions and number of workarounds for operations without
+	  certificates. Proof of concept type of experimental patch is
+	  included in openssl-tls-extensions.patch.
+
+2004-12-19 - v0.3.2
+	* fixed private key loading for cases where passphrase is not set
+	* fixed Windows/cygwin L2 packet handler freeing; previous version
+	  could cause a segfault when RSN pre-authentication was completed
+	* added support for PMKSA caching with drivers that generate RSN IEs
+	  (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
+	  but similar code can be easily added to driver_ndiswrapper.c once
+	  ndiswrapper gets full support for RSN PMKSA caching
+	* improved recovery from PMKID mismatches by requesting full EAP
+	  authentication in case of failed PMKSA caching attempt
+	* driver_ndis: added support for NDIS NdisMIncidateStatus() events
+	  (this requires that ndis_events is ran while wpa_supplicant is
+	  running)
+	* driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
+	* added support for driver interfaces to replace the interface name
+	  based on driver/OS specific mapping, e.g., in case of driver_ndis,
+	  this allows the beginning of the adapter description to be used as
+	  the interface name
+	* added support for CR+LF (Windows-style) line ends in configuration
+	  file
+	* driver_ndis: enable radio before starting scanning, disable radio
+	  when exiting
+	* modified association event handler to set portEnabled = FALSE before
+	  clearing port Valid in order to reset EAP state machine and avoid
+	  problems with new authentication getting ignored because of state
+	  machines ending up in AUTHENTICATED/SUCCESS state based on old
+	  information
+	* added support for driver events to add PMKID candidates in order to
+	  allow drivers to give priority to most likely roaming candidates
+	* driver_hostap: moved PrivacyInvoked configuration to associate()
+	  function so that this will not be set for plaintext connections
+	* added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
+	  interface can distinguish plaintext and IEEE 802.1X (no WPA)
+	  authentication
+	* fixed static WEP key configuration to use broadcast/default type for
+	  all keys (previously, the default TX key was configured as pairwise/
+	  unicast key)
+	* driver_ndis: added legacy WPA capability detection for non-WPA2
+	  drivers
+	* added support for setting static WEP keys for IEEE 802.1X without
+	  dynamic WEP keying (eapol_flags=0)
+
+2004-12-12 - v0.3.1
+	* added support for reading PKCS#12 (PFX) files (as a replacement for
+	  PEM/DER) to get certificate and private key (CONFIG_PKCS12)
+	* fixed compilation with CONFIG_PCSC=y
+	* added new ap_scan mode, ap_scan=2, for drivers that take care of
+	  association, but need to be configured with security policy and SSID,
+	  e.g., ndiswrapper and NDIS driver; this mode should allow such
+	  drivers to work with hidden SSIDs and optimized roaming; when
+	  ap_scan=2 is used, only the first network block in the configuration
+	  file is used and this configuration should have explicit security
+	  policy (i.e., only one option in the lists) for key_mgmt, pairwise,
+	  group, proto variables
+	* added experimental port of wpa_supplicant for Windows
+	  - driver_ndis.c driver interface (NDIS OIDs)
+	  - currently, this requires cygwin and WinPcap
+	  - small utility, win_if_list, can be used to get interface name
+	* control interface can now be removed at build time; add
+	  CONFIG_CTRL_IFACE=y to .config to maintain old functionality
+	* optional Xsupplicant interface can now be removed at build time;
+	  (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
+	* added auth_alg to driver interface associate() parameters to make it
+	  easier for drivers to configure authentication algorithm as part of
+	  the association
+
+2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
+	* driver_broadcom: added new driver interface for Broadcom wl.o driver
+	  (a generic driver for Broadcom IEEE 802.11a/g cards)
+	* wpa_cli: fixed parsing of -p <path> command line argument
+	* PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
+	  ACK, not tunneled EAP-Success (of which only the first byte was
+	  actually send due to a bug in previous code); this seems to
+	  interoperate with most RADIUS servers that implements PEAPv1
+	* PEAPv1: added support for terminating PEAP authentication on tunneled
+	  EAP-Success message; this can be configured by adding
+	  peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
+	  (some RADIUS servers require this whereas others require a tunneled
+	  reply
+	* PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
+	  the old label for key derivation; previously, the default was 1,
+	  but it looks like most existing PEAPv1 implementations use the old
+	  label which is thus more suitable default option
+	* added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
+	* fixed parsing of wep_tx_keyidx
+	* added support for configuring list of allowed Phase 2 EAP types
+	  (for both EAP-PEAP and EAP-TTLS) instead of only one type
+	* added support for configuring IEEE 802.11 authentication algorithm
+	  (auth_alg; mainly for using Shared Key authentication with static
+	  WEP keys)
+	* added support for EAP-AKA (with UMTS SIM)
+	* fixed couple of errors in PCSC handling that could have caused
+	  random-looking errors for EAP-SIM
+	* added support for EAP-SIM pseudonyms and fast re-authentication
+	* added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
+	  session resumption)
+	* added support for EAP-SIM with two challanges
+	  (phase1="sim_min_num_chal=3" can be used to require three challenges)
+	* added support for configuring DH/DSA parameters for an ephemeral DH
+	  key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
+	  dh_file and dh_file2 (phase 2); this adds support for using DSA keys
+	  and optional DH key exchange to achieve forward secracy with RSA keys
+	* added support for matching subject of the authentication server
+	  certificate with a substring when using EAP-TLS/PEAP/TTLS; new
+	  configuration variables subject_match and subject_match2
+	* changed SSID configuration in driver_wext.c (used by many driver
+	  interfaces) to use ssid_len+1 as the length for SSID since some Linux
+	  drivers expect this
+	* fixed couple of unaligned reads in scan result parsing to fix WPA
+	  connection on some platforms (e.g., ARM)
+	* added driver interface for Intel ipw2100 driver
+	* added support for LEAP with WPA
+	* added support for larger scan results report (old limit was 4 kB of
+	  data, i.e., about 35 or so APs) when using Linux wireless extensions
+	  v17 or newer
+	* fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
+	  only if there is a PMKSA cache entry for the current AP
+	* fixed error handling for case where reading of scan results fails:
+	  must schedule a new scan or wpa_supplicant will remain waiting
+	  forever
+	* changed debug output to remove shared password/key material by
+	  default; all key information can be included with -K command line
+	  argument to match the previous behavior
+	* added support for timestamping debug log messages (disabled by
+	  default, can be enabled with -t command line argument)
+	* set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
+	  if keys are not configured to be used; this fixes IEEE 802.1X mode
+	  with drivers that use this information to configure whether Privacy
+	  bit can be in Beacon frames (e.g., ndiswrapper)
+	* avoid clearing driver keys if no keys have been configured since last
+	  key clear request; this seems to improve reliability of group key
+	  handshake for ndiswrapper & NDIS driver which seems to be suffering
+	  of some kind of timing issue when the keys are cleared again after
+	  association
+	* changed driver interface API:
+	  - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
+	    version is being used (now, this is set to 2; previously, it was
+	    not defined)
+	  - pass pointer to private data structure to all calls
+	  - the new API is not backwards compatible; all in-tree driver
+	    interfaces has been converted to the new API
+	* added support for controlling multiple interfaces (radios) per
+	  wpa_supplicant process; each interface needs to be listed on the
+	  command line (-c, -i, -D arguments) with -N as a separator
+	  (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
+	* added a workaround for EAP servers that incorrectly use same Id for
+	  sequential EAP packets
+	* changed libpcap/libdnet configuration to use .config variable,
+	  CONFIG_DNET_PCAP, instead of requiring Makefile modification
+	* improved downgrade attack detection in IE verification of msg 3/4:
+	  verify both WPA and RSN IEs, if present, not only the selected one;
+	  reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
+	  Probe Response frame, and RSN is enabled in wpa_supplicant
+	  configuration
+	* fixed WPA msg 3/4 processing to allow Key Data field contain other
+	  IEs than just one WPA IE
+	* added support for FreeBSD and driver interface for the BSD net80211
+	  layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
+	  required kernel mods have not yet been committed
+	* made EAP workarounds configurable; enabled by default, can be
+	  disabled with network block option eap_workaround=0
+
+2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
+	* resolved couple of interoperability issues with EAP-PEAPv1 and
+	  Phase 2 (inner EAP) fragment reassembly
+	* driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
+	  AP is using non-zero key index for the unicast key and key index zero
+	  for the broadcast key
+	* driver_hostap: fixed IEEE 802.1X WEP key updates and
+	  re-authentication by allowing unencrypted EAPOL frames when not using
+	  WPA
+	* added a new driver interface, 'wext', which uses only standard,
+	  driver independent functionality in Linux wireless extensions;
+	  currently, this can be used only for non-WPA IEEE 802.1X mode, but
+	  eventually, this is to be extended to support full WPA/WPA2 once
+	  Linux wireless extensions get support for this
+	* added support for mode in which the driver is responsible for AP
+	  scanning and selection; this is disabled by default and can be
+	  enabled with global ap_scan=0 variable in wpa_supplicant.conf;
+	  this mode can be used, e.g., with generic 'wext' driver interface to
+	  use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
+	  supporting wireless extensions.
+	* driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
+	  operation with an AP that does not include SSID in the Beacon frames)
+	* added support for new EAP authentication methods:
+	  EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
+	* added support for asking one-time-passwords from frontends (e.g.,
+	  wpa_cli); this 'otp' command works otherwise like 'password' command,
+	  but the password is used only once and the frontend will be asked for
+	  a new password whenever a request from authenticator requires a
+	  password; this can be used with both EAP-OTP and EAP-GTC
+	* changed wpa_cli to automatically re-establish connection so that it
+	  does not need to be re-started when wpa_supplicant is terminated and
+	  started again
+	* improved user data (identity/password/otp) requests through
+	  frontends: process pending EAPOL packets after getting new
+	  information so that full authentication does not need to be
+	  restarted; in addition, send pending requests again whenever a new
+	  frontend is attached
+	* changed control frontends to use a new directory for socket files to
+	  make it easier for wpa_cli to automatically select between interfaces
+	  and to provide access control for the control interface;
+	  wpa_supplicant.conf: ctrl_interface is now a path
+	  (/var/run/wpa_supplicant is the recommended path) and
+	  ctrl_interface_group can be used to select which group gets access to
+	  the control interface;
+	  wpa_cli: by default, try to connect to the first interface available
+	  in /var/run/wpa_supplicant; this path can be overriden with -p option
+	  and an interface can be selected with -i option (i.e., in most common
+	  cases, wpa_cli does not need to get any arguments)
+	* added support for LEAP
+	* added driver interface for Linux ndiswrapper
+	* added priority option for network blocks in the configuration file;
+	  this allows networks to be grouped based on priority (the scan
+	  results are searched for matches with network blocks in this order)
+
+2004-06-20 - v0.2.3
+	* sort scan results to improve AP selection
+	* fixed control interface socket removal for some error cases
+	* improved scan requesting and authentication timeout
+	* small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
+	  TLS processing
+	* PEAP version can now be forced with phase1="peapver=<ver>"
+	  (mostly for testing; by default, the highest version supported by
+	  both the Supplicant and Authentication Server is selected
+	  automatically)
+	* added support for madwifi driver (Atheros ar521x)
+	* added a workaround for cases where AP sets Install Tx/Rx bit for
+	  WPA Group Key messages when pairwise keys are used (without this,
+	  the Group Key would be used for Tx and the AP would drop frames
+	  from the station)
+	* added GSM SIM/USIM interface for GSM authentication algorithm for
+	  EAP-SIM; this requires pcsc-lite
+	* added support for ATMEL AT76C5XXx driver
+	* fixed IEEE 802.1X WEP key derivation in the case where Authenticator
+	  does not include key data in the EAPOL-Key frame (i.e., part of
+	  EAP keying material is used as data encryption key)
+	* added support for using plaintext and static WEP networks
+	  (key_mgmt=NONE)
+
+2004-05-31 - v0.2.2
+	* added support for new EAP authentication methods:
+	  EAP-TTLS/EAP-MD5-Challenge
+	  EAP-TTLS/EAP-GTC
+	  EAP-TTLS/EAP-MSCHAPv2
+	  EAP-TTLS/EAP-TLS
+	  EAP-TTLS/MSCHAPv2
+	  EAP-TTLS/MSCHAP
+	  EAP-TTLS/PAP
+	  EAP-TTLS/CHAP
+	  EAP-PEAP/TLS
+	  EAP-PEAP/GTC
+	  EAP-PEAP/MD5-Challenge
+	  EAP-GTC
+	  EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
+	* added support for anonymous identity (to be used when identity is
+	  sent in plaintext; real identity will be used within TLS protected
+	  tunnel (e.g., with EAP-TTLS)
+	* added event messages from wpa_supplicant to frontends, e.g., wpa_cli
+	* added support for requesting identity and password information using
+	  control interface; in other words, the password for EAP-PEAP or
+	  EAP-TTLS does not need to be included in the configuration file since
+	  a frontand (e.g., wpa_cli) can ask it from the user
+	* improved RSN pre-authentication to use a candidate list and process
+	  all candidates from each scan; not only one per scan
+	* fixed RSN IE and WPA IE capabilities field parsing
+	* ignore Tx bit in GTK IE when Pairwise keys are used
+	* avoid making new scan requests during IEEE 802.1X negotiation
+	* use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
+	  with TLS support (this replaces the included implementation with
+	  library code to save about 8 kB since the library code is needed
+	  anyway for TLS)
+	* fixed WPA-PSK only mode when compiled without IEEE 802.1X support
+	  (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
+
+2004-05-06 - v0.2.1
+	* added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
+	  Supplicant
+	  - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
+	  - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
+	  - EAP-MD5 (cannot be used with WPA-RADIUS)
+	    [draft-ietf-eap-rfc2284bis-09.txt]
+	  - EAP-TLS [RFC 2716]
+	  - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
+	  - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
+	    [draft-kamath-pppext-eap-mschapv2-00.txt]
+	    (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
+	    default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
+	  - new configuration file options: eap, identity, password, ca_cert,
+	    client_cert, privatekey, private_key_passwd
+	  - Xsupplicant is not required anymore, but it can be used by
+	    disabling the internal IEEE 802.1X Supplicant with -e command line
+	    option
+	  - this code is not included in the default build; Makefile need to
+	    be edited for this (uncomment lines for selected functionality)
+	  - EAP-TLS and EAP-PEAP require openssl libraries
+	* use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
+	* added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
+	  (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
+	   EAPOL-Key frames instead of WPA key handshakes)
+	* added support for IEEE 802.11i/RSN (WPA2)
+	  - improved PTK Key Handshake
+	  - PMKSA caching, pre-authentication
+	* fixed wpa_supplicant to ignore possible extra data after WPA
+	  EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
+	  TPTK' error from message 3 of 4-Way Handshake in case the AP
+	  includes extra data after the EAPOL-Key)
+	* added interface for external programs (frontends) to control
+	  wpa_supplicant
+	  - CLI example (wpa_cli) with interactive mode and command line
+	    mode
+	  - replaced SIGUSR1 status/statistics with the new control interface
+	* made some feature compile time configurable
+	  - .config file for make
+	  - driver interfaces (hostap, hermes, ..)
+	  - EAPOL/EAP functions
+
+2004-02-15 - v0.2.0
+	* Initial version of wpa_supplicant

+Requirements
+------------
+
+Current hardware/software requirements:
+- Linux kernel 2.4.x or 2.6.x with Linux Wireless Extensions v15 or newer
+- FreeBSD 6-CURRENT
+- Microsoft Windows with WinPcap (at least WinXP, may work with other versions)
+- drivers:
+	Host AP driver for Prism2/2.5/3 (development snapshot/v0.2.x)
+	(http://hostap.epitest.fi/)
+	Driver need to be set in Managed mode ('iwconfig wlan0 mode managed').
+	Please note that station firmware version needs to be 1.7.0 or newer
+	to work in WPA mode.
+
+	Linuxant DriverLoader (http://www.linuxant.com/driverloader/)
+	with Windows NDIS driver for your wlan card supporting WPA.
+
+	Agere Systems Inc. Linux Driver
+	(http://www.agere.com/support/drivers/)
+	Please note that the driver interface file (driver_hermes.c) and
+	hardware specific include files are not included in the
+	wpa_supplicant distribution. You will need to copy these from the
+	source package of the Agere driver.
+
+	madwifi driver for cards based on Atheros chip set (ar521x)
+	(http://sourceforge.net/projects/madwifi/)
+	Please note that you will need to modify the wpa_supplicant .config
+	file to use the correct path for the madwifi driver root directory
+	(CFLAGS += -I../madwifi/wpa line in example defconfig).
+
+	ATMEL AT76C5XXx driver for USB and PCMCIA cards
+	(http://atmelwlandriver.sourceforge.net/).
+
+	Linux ndiswrapper (http://ndiswrapper.sourceforge.net/) with
+	Windows NDIS driver.
+
+	Broadcom wl.o driver
+	This is a generic Linux driver for Broadcom IEEE 802.11a/g cards.
+	However, it is proprietary driver that is not publicly available
+	except for couple of exceptions, mainly Broadcom-based APs/wireless
+	routers that use Linux. The driver binary can be downloaded, e.g.,
+	from Linksys support site (http://www.linksys.com/support/gpl.asp)
+	for Linksys WRT54G. The GPL tarball includes cross-compiler and
+	the needed header file, wlioctl.h, for compiling wpa_supplicant.
+	This driver support in wpa_supplicant is expected to work also with
+	other devices based on Broadcom driver (assuming the driver includes
+	client mode support).
+
+	Intel ipw2100 driver
+	(http://sourceforge.net/projects/ipw2100/)
+
+	Intel ipw2200 driver
+	(http://sourceforge.net/projects/ipw2200/)
+
+	In theory, any driver that supports Linux wireless extensions can be
+	used with IEEE 802.1X (i.e., not WPA) when using ap_scan=0 option in
+	configuration file.
+
+	BSD net80211 layer (e.g., Atheros driver)
+	At the moment, this is for FreeBSD 6-CURRENT branch.
+
+	Windows NDIS
+	The current Windows port requires WinPcap (http://winpcap.polito.it/).
+	See README-Windows.txt for more information.
+
+wpa_supplicant was designed to be portable for different drivers and
+operating systems. Hopefully, support for more wlan cards and OSes will be
+added in the future. See developer.txt for more information about the
+design of wpa_supplicant and porting to other drivers. One main goal
+is to add full WPA/WPA2 support to Linux wireless extensions to allow
+new drivers to be supported without having to implement new
+driver-specific interface code in wpa_supplicant.
+
+Optional libraries for layer2 packet processing:
+- libpcap (tested with 0.7.2, most relatively recent versions assumed to work,
+	this is likely to be available with most distributions,
+	http://tcpdump.org/)
+- libdnet (tested with v1.4, most versions assumed to work,
+	http://libdnet.sourceforge.net/)
+
+These libraries are _not_ used in the default Linux build. Instead,
+internal Linux specific implementation is used. libpcap/libdnet are
+more portable and they can be used by adding CONFIG_DNET_PCAP=y into
+.config. They may also be selected automatically for other operating
+systems.
+
+
+Optional libraries for EAP-TLS, EAP-PEAP, and EAP-TTLS:
+- openssl (tested with 0.9.7c and 0.9.7d, assumed to work with most
+  relatively recent versions; this is likely to be available with most
+  distributions, http://www.openssl.org/)
+
+This library is only needed when EAP-TLS, EAP-PEAP, or EAP-TTLS
+support is enabled. WPA-PSK mode does not require this or EAPOL/EAP
+implementation. A configuration file, .config, for compilation is
+needed to enable IEEE 802.1X/EAPOL and EAP methods. Note that EAP-MD5,
+EAP-GTC, EAP-OTP, and EAP-MSCHAPV2 cannot be used alone with WPA, so
+they should only be enabled if testing the EAPOL/EAP state
+machines. However, there can be used as inner authentication
+algorithms with EAP-PEAP and EAP-TTLS.
+
+See Building and installing section below for more detailed
+information about the wpa_supplicant build time configuration.
+
+
+
+WPA
+---
+
+The original security mechanism of IEEE 802.11 standard was not
+designed to be strong and has proven to be insufficient for most
+networks that require some kind of security. Task group I (Security)
+of IEEE 802.11 working group (http://www.ieee802.org/11/) has worked
+to address the flaws of the base standard and has in practice
+completed its work in May 2004. The IEEE 802.11i amendment to the IEEE
+802.11 standard was approved in June 2004 and this amendment is likely
+to be published in July 2004.
+
+Wi-Fi Alliance (http://www.wi-fi.org/) used a draft version of the
+IEEE 802.11i work (draft 3.0) to define a subset of the security
+enhancements that can be implemented with existing wlan hardware. This
+is called Wi-Fi Protected Access<TM> (WPA). This has now become a
+mandatory component of interoperability testing and certification done
+by Wi-Fi Alliance. Wi-Fi provides information about WPA at its web
+site (http://www.wi-fi.org/OpenSection/protected_access.asp).
+
+IEEE 802.11 standard defined wired equivalent privacy (WEP) algorithm
+for protecting wireless networks. WEP uses RC4 with 40-bit keys,
+24-bit initialization vector (IV), and CRC32 to protect against packet
+forgery. All these choices have proven to be insufficient: key space is
+too small against current attacks, RC4 key scheduling is insufficient
+(beginning of the pseudorandom stream should be skipped), IV space is
+too small and IV reuse makes attacks easier, there is no replay
+protection, and non-keyed authentication does not protect against bit
+flipping packet data.
+
+WPA is an intermediate solution for the security issues. It uses
+Temporal Key Integrity Protocol (TKIP) to replace WEP. TKIP is a
+compromise on strong security and possibility to use existing
+hardware. It still uses RC4 for the encryption like WEP, but with
+per-packet RC4 keys. In addition, it implements replay protection,
+keyed packet authentication mechanism (Michael MIC).
+
+Keys can be managed using two different mechanisms. WPA can either use
+an external authentication server (e.g., RADIUS) and EAP just like
+IEEE 802.1X is using or pre-shared keys without need for additional
+servers. Wi-Fi calls these "WPA-Enterprise" and "WPA-Personal",
+respectively. Both mechanisms will generate a master session key for
+the Authenticator (AP) and Supplicant (client station).
+
+WPA implements a new key handshake (4-Way Handshake and Group Key
+Handshake) for generating and exchanging data encryption keys between
+the Authenticator and Supplicant. This handshake is also used to
+verify that both Authenticator and Supplicant know the master session
+key. These handshakes are identical regardless of the selected key
+management mechanism (only the method for generating master session
+key changes).
+
+
+
+IEEE 802.11i / WPA2
+-------------------
+
+The design for parts of IEEE 802.11i that were not included in WPA has
+finished (May 2004) and this amendment to IEEE 802.11 was approved in
+June 2004. Wi-Fi Alliance is using the final IEEE 802.11i as a new
+version of WPA called WPA2. This includes, e.g., support for more
+robust encryption algorithm (CCMP: AES in Counter mode with CBC-MAC)
+to replace TKIP and optimizations for handoff (reduced number of
+messages in initial key handshake, pre-authentication, and PMKSA caching).
+
+Some wireless LAN vendors are already providing support for CCMP in
+their WPA products. There is no "official" interoperability
+certification for CCMP and/or mixed modes using both TKIP and CCMP, so
+some interoperability issues can be expected even though many
+combinations seem to be working with equipment from different vendors.
+Certification for WPA2 is likely to start during the second half of
+2004.
+
+
+
+wpa_supplicant
+--------------
+
+wpa_supplicant is an implementation of the WPA Supplicant component,
+i.e., the part that runs in the client stations. It implements WPA key
+negotiation with a WPA Authenticator and EAP authentication with
+Authentication Server. In addition, it controls the roaming and IEEE
+802.11 authentication/association of the wlan driver.
+
+wpa_supplicant is designed to be a "daemon" program that runs in the
+background and acts as the backend component controlling the wireless
+connection. wpa_supplicant supports separate frontend programs and an
+example text-based frontend, wpa_cli, is included with wpa_supplicant.
+
+Following steps are used when associating with an AP using WPA:
+
+- wpa_supplicant requests the kernel driver to scan neighboring BSSes
+- wpa_supplicant selects a BSS based on its configuration
+- wpa_supplicant requests the kernel driver to associate with the chosen
+  BSS
+- If WPA-EAP: integrated IEEE 802.1X Supplicant or external Xsupplicant
+  completes EAP authentication with the authentication server (proxied
+  by the Authenticator in the AP)
+- If WPA-EAP: master key is received from the IEEE 802.1X Supplicant
+- If WPA-PSK: wpa_supplicant uses PSK as the master session key
+- wpa_supplicant completes WPA 4-Way Handshake and Group Key Handshake
+  with the Authenticator (AP)
+- wpa_supplicant configures encryption keys for unicast and broadcast
+- normal data packets can be transmitted and received
+
+
+
+Building and installing
+-----------------------
+
+In order to be able to build wpa_supplicant, you will first need to
+select which parts of it will be included. This is done by creating a
+build time configuration file, .config, in the wpa_supplicant root
+directory. Configuration options are text lines using following
+format: CONFIG_<option>=y. Lines starting with # are considered
+comments and are ignored. See defconfig file for example configuration
+and list of available option.
+
+The build time configuration can be used to select only the needed
+features and limit the binary size and requirements for external
+libraries. The main configuration parts are the selection of which
+driver interfaces (e.g., hostap, madwifi, ..) and which authentication
+methods (e.g., EAP-TLS, EAP-PEAP, ..) are included.
+
+Following build time configuration options are used to control IEEE
+802.1X/EAPOL and EAP state machines and all EAP methods. Including
+TLS, PEAP, or TTLS will require linking wpa_supplicant with openssl
+library for TLS implementation.
+
+CONFIG_IEEE8021X_EAPOL=y
+CONFIG_EAP_MD5=y
+CONFIG_EAP_MSCHAPV2=y
+CONFIG_EAP_TLS=y
+CONFIG_EAP_PEAP=y
+CONFIG_EAP_TTLS=y
+CONFIG_EAP_GTC=y
+CONFIG_EAP_OTP=y
+CONFIG_EAP_SIM=y
+CONFIG_EAP_AKA=y
+CONFIG_EAP_PSK=y
+CONFIG_EAP_LEAP=y
+
+Following option can be used to include GSM SIM/USIM interface for GSM/UMTS
+authentication algorithm (for EAP-SIM/EAP-AKA). This requires pcsc-lite
+(http://www.linuxnet.com/) for smart card access.
+
+CONFIG_PCSC=y
+
+Following option can be used to replace the native Linux packet socket
+interface with libpcap/libdnet.
+
+CONFIG_DNET_PCAP=y
+
+Following options can be added to .config to select which driver
+interfaces are included. Prism54.org driver is not yet complete and
+Hermes driver interface needs to be downloaded from Agere (see above).
+Most Linux driver need to include CONFIG_WIRELESS_EXTENSION.
+
+CONFIG_WIRELESS_EXTENSION=y
+CONFIG_DRIVER_HOSTAP=y
+CONFIG_DRIVER_PRISM54=y
+CONFIG_DRIVER_HERMES=y
+CONFIG_DRIVER_MADWIFI=y
+CONFIG_DRIVER_ATMEL=y
+CONFIG_DRIVER_WEXT=y
+CONFIG_DRIVER_NDISWRAPPER=y
+CONFIG_DRIVER_BROADCOM=y
+CONFIG_DRIVER_IPW=y
+CONFIG_DRIVER_BSD=y
+CONFIG_DRIVER_NDIS=y
+
+Following example includes all features and driver interfaces that are
+included in the wpa_supplicant package:
+
+CONFIG_DRIVER_HOSTAP=y
+CONFIG_DRIVER_PRISM54=y
+CONFIG_DRIVER_HERMES=y
+CONFIG_DRIVER_MADWIFI=y
+CONFIG_DRIVER_ATMEL=y
+CONFIG_DRIVER_WEXT=y
+CONFIG_DRIVER_NDISWRAPPER=y
+CONFIG_DRIVER_BROADCOM=y
+CONFIG_DRIVER_IPW=y
+CONFIG_DRIVER_BSD=y
+CONFIG_DRIVER_NDIS=y
+CONFIG_WIRELESS_EXTENSION=y
+CONFIG_IEEE8021X_EAPOL=y
+CONFIG_EAP_MD5=y
+CONFIG_EAP_MSCHAPV2=y
+CONFIG_EAP_TLS=y
+CONFIG_EAP_PEAP=y
+CONFIG_EAP_TTLS=y
+CONFIG_EAP_GTC=y
+CONFIG_EAP_OTP=y
+CONFIG_EAP_SIM=y
+CONFIG_EAP_AKA=y
+CONFIG_EAP_PSK=y
+CONFIG_EAP_LEAP=y
+CONFIG_PCSC=y
+
+EAP-PEAP and EAP-TTLS will automatically include configured EAP
+methods (MD5, OTP, GTC, MSCHAPV2) for inner authentication selection.
+
+
+After you have created a configuration file, you can build
+wpa_supplicant and wpa_cli with 'make' command. You may then install
+the binaries to a suitable system directory, e.g., /usr/local/bin.
+
+Example commands:
+
+# build wpa_supplicant and wpa_cli
+make
+# install binaries (this may need root privileges)
+cp wpa_cli wpa_supplicant /usr/local/bin
+
+
+You will need to make a configuration file, e.g.,
+/etc/wpa_supplicant.conf, with network configuration for the networks
+you are going to use. Configuration file section below includes
+explanation fo the configuration file format and includes various
+examples. Once the configuration is ready, you can test whether the
+configuration work by first running wpa_supplicant with following
+command to start it on foreground with debugging enabled:
+
+wpa_supplicant -iwlan0 -c/etc/wpa_supplicant.conf -d
+
+Assuming everything goes fine, you can start using following command
+to start wpa_supplicant on background without debugging:
+
+wpa_supplicant -iwlan0 -c/etc/wpa_supplicant.conf -B
+
+Please note that if you included more than one driver interface in the
+build time configuration (.config), you may need to specify which
+interface to use by including -D<driver name> option on the command
+line. See following section for more details on command line options
+for wpa_supplicant.
+
+
+
+Command line options
+--------------------
+
+usage:
+  wpa_supplicant [-BddehLqqvw] -i<ifname> -c<config file> [-D<driver>] \
+      [-N -i<ifname> -c<conf> [-D<driver>] ...]
+
+options:
+  -B = run daemon in the background
+  -d = increase debugging verbosity (-dd even more)
+  -K = include keys (passwords, etc.) in debug output
+  -t = include timestamp in debug messages
+  -e = use external IEEE 802.1X Supplicant (e.g., xsupplicant)
+       (this disables the internal Supplicant)
+  -h = show this help text
+  -L = show license (GPL and BSD)
+  -q = decrease debugging verbosity (-qq even less)
+  -v = show version
+  -w = wait for interface to be added, if needed
+  -N = start describing new interface
+
+drivers:
+  hostap = Host AP driver (Intersil Prism2/2.5/3) [default]
+	(this can also be used with Linuxant DriverLoader)
+  prism54 = Prism54.org driver (Intersil Prism GT/Duette/Indigo)
+	not yet fully implemented
+  hermes = Agere Systems Inc. driver (Hermes-I/Hermes-II)
+  madwifi = MADWIFI 802.11 support (Atheros, etc.)
+  atmel = ATMEL AT76C5XXx (USB, PCMCIA)
+  wext = Linux wireless extensions (generic)
+  ndiswrapper = Linux ndiswrapper
+  broadcom = Broadcom wl.o driver
+  ipw = Intel ipw2100/2200 driver
+  bsd = BSD 802.11 support (Atheros, etc.)
+  ndis = Windows NDIS driver
+
+In most common cases, wpa_supplicant is started with
+
+wpa_supplicant -Bw -c/etc/wpa_supplicant.conf -iwlan0
+
+This makes the process fork into background and wait for the wlan0
+interface if it is not available at startup time.
+
+The easiest way to debug problems, and to get debug log for bug
+reports, is to start wpa_supplicant on foreground with debugging
+enabled:
+
+wpa_supplicant -c/etc/wpa_supplicant.conf -iwlan0 -d
+
+
+wpa_supplicant can control multiple interfaces (radios) either by
+running one process for each interface separately or by running just
+one process and list of options at command line. Each interface is
+separated with -N argument. As an example, following command would
+start wpa_supplicant for two interfaces:
+
+wpa_supplicant \
+	-c wpa1.conf -i wlan0 -D hostap -N \
+	-c wpa2.conf -i ath0 -D madwifi
+
+
+Configuration file
+------------------
+
+wpa_supplicant is configured using a text file that lists all accepted
+networks and security policies, including pre-shared keys. See
+example configuration file, wpa_supplicant.conf, for detailed
+information about the configuration format and supported fields.
+
+Changes to configuration file can be reloaded be sending SIGHUP signal
+to wpa_supplicant ('killall -HUP wpa_supplicant'). Similarly,
+reloading can be triggered with 'wpa_cli reconfigure' command.
+
+Configuration file can include one or more network blocks, e.g., one
+for each used SSID. wpa_supplicant will automatically select the best
+betwork based on the order of network blocks in the configuration
+file, network security level (WPA/WPA2 is prefered), and signal
+strength.
+
+Example configuration files for some common configurations:
+
+1) WPA-Personal (PSK) as home network and WPA-Enterprise with EAP-TLS as work
+   network
+
+# allow frontend (e.g., wpa_cli) to be used by all users in 'wheel' group
+ctrl_interface=/var/run/wpa_supplicant
+ctrl_interface_group=wheel
+#
+# home network; allow all valid ciphers
+network={
+	ssid="home"
+	scan_ssid=1
+	key_mgmt=WPA-PSK
+	psk="very secret passphrase"
+}
+#
+# work network; use EAP-TLS with WPA; allow only CCMP and TKIP ciphers
+network={
+	ssid="work"
+	scan_ssid=1
+	key_mgmt=WPA-EAP
+	pairwise=CCMP TKIP
+	group=CCMP TKIP
+	eap=TLS
+	identity="user@example.com"
+	ca_cert="/etc/cert/ca.pem"
+	client_cert="/etc/cert/user.pem"
+	private_key="/etc/cert/user.prv"
+	private_key_passwd="password"
+}
+
+
+2) WPA-RADIUS/EAP-PEAP/MSCHAPv2 with RADIUS servers that use old peaplabel
+   (e.g., Funk Odyssey and SBR, Meetinghouse Aegis, Interlink RAD-Series)
+
+ctrl_interface=/var/run/wpa_supplicant
+ctrl_interface_group=wheel
+network={
+	ssid="example"
+	scan_ssid=1
+	key_mgmt=WPA-EAP
+	eap=PEAP
+	identity="user@example.com"
+	password="foobar"
+	ca_cert="/etc/cert/ca.pem"
+	phase1="peaplabel=0"
+	phase2="auth=MSCHAPV2"
+}
+
+
+3) EAP-TTLS/EAP-MD5-Challenge configuration with anonymous identity for the
+   unencrypted use. Real identity is sent only within an encrypted TLS tunnel.
+
+ctrl_interface=/var/run/wpa_supplicant
+ctrl_interface_group=wheel
+network={
+	ssid="example"
+	scan_ssid=1
+	key_mgmt=WPA-EAP
+	eap=TTLS
+	identity="user@example.com"
+	anonymous_identity="anonymous@example.com"
+	password="foobar"
+	ca_cert="/etc/cert/ca.pem"
+	phase2="auth=MD5"
+}
+
+
+4) IEEE 802.1X (i.e., no WPA) with dynamic WEP keys (require both unicast and
+   broadcast); use EAP-TLS for authentication
+
+ctrl_interface=/var/run/wpa_supplicant
+ctrl_interface_group=wheel
+network={
+	ssid="1x-test"
+	scan_ssid=1
+	key_mgmt=IEEE8021X
+	eap=TLS
+	identity="user@example.com"
+	ca_cert="/etc/cert/ca.pem"
+	client_cert="/etc/cert/user.pem"
+	private_key="/etc/cert/user.prv"
+	private_key_passwd="password"
+	eapol_flags=3
+}
+
+
+5) Catch all example that allows more or less all configuration modes. The
+   configuration options are used based on what security policy is used in the
+   selected SSID. This is mostly for testing and is not recommended for normal
+   use.
+
+ctrl_interface=/var/run/wpa_supplicant
+ctrl_interface_group=wheel
+network={
+	ssid="example"
+	scan_ssid=1
+	key_mgmt=WPA-EAP WPA-PSK IEEE8021X NONE
+	pairwise=CCMP TKIP
+	group=CCMP TKIP WEP104 WEP40
+	psk="very secret passphrase"
+	eap=TTLS PEAP TLS
+	identity="user@example.com"
+	password="foobar"
+	ca_cert="/etc/cert/ca.pem"
+	client_cert="/etc/cert/user.pem"
+	private_key="/etc/cert/user.prv"
+	private_key_passwd="password"
+	phase1="peaplabel=0"
+	ca_cert2="/etc/cert/ca2.pem"
+	client_cert2="/etc/cer/user.pem"
+	private_key2="/etc/cer/user.prv"
+	private_key2_passwd="password"
+}
+
+
+
+Certificates
+------------
+
+Some EAP authentication methods require use of certificates. EAP-TLS
+uses both server side and client certificates whereas EAP-PEAP and
+EAP-TTLS only require the server side certificate. When client
+certificate is used, a matching private key file has to also be
+included in configuration. If the private key uses a passphrase, this
+has to be configured in wpa_supplicant.conf ("private_key_passwd").
+
+wpa_supplicant supports X.509 certificates in PEM and DER
+formats. User certificate and private key can be included in the same
+file.
+
+If the user certificate and private key is received in PKCS#12/PFX
+format, they need to be converted to suitable PEM/DER format for
+wpa_supplicant. This can be done, e.g., with following commands:
+
+# convert client certificate and private key to PEM format
+openssl pkcs12 -in example.pfx -out user.pem -clcerts
+# convert CA certificate (if included in PFX file) to PEM format
+openssl pkcs12 -in example.pfx -out ca.pem -cacerts -nokeys
+
+
+
+wpa_cli
+-------
+
+wpa_cli is a text-based frontend program for interacting with
+wpa_supplicant. It is used to query current status, change
+configuration, trigger events, and request interactive user input.
+
+wpa_cli can show the current authentication status, selected security
+mode, dot11 and dot1x MIBs, etc. In addition, it can configuring some
+variables like EAPOL state machine parameters and trigger events like
+reassociation and IEEE 802.1X logoff/logon. wpa_cli provides a user
+interface to request authentication information, like username and
+password, if these are not included in the configuration. This can be
+used to implement, e.g., one-time-passwords or generic token card
+authentication where the authentication is based on a
+challenge-response that uses an external device for generating the
+response.
+
+The control interface of wpa_supplicant can be configured to allow
+non-root user access (ctrl_interface_group in the configuration
+file). This makes it possible to run wpa_cli with a normal user
+account.
+
+wpa_cli supports two modes: interactive and command line. Both modes
+share the same command set and the main difference is in interactive
+mode providing access to unsolicited messages (event messages,
+username/password requests).
+
+Interactive mode is started when wpa_cli is executed without including
+the command as a command line parameter. Commands are then entered on
+the wpa_cli prompt. In command line mode, the same commands are
+entered as command line arguments for wpa_cli.
+
+
+Interactive authentication parameters request
+
+When wpa_supplicant need authentication parameters, like username and
+password, which are not present in the configuration file, it sends a
+request message to all attached frontend programs, e.g., wpa_cli in
+interactive mode. wpa_cli shows these requests with
+"CTRL-REQ-<type>-<id>:<text>" prefix. <type> is IDENTITY, PASSWORD, or
+OTP (one-time-password). <id> is a unique identifier for the current
+network. <text> is description of the request. In case of OTP request,
+it includes the challenge from the authentication server.
+
+The reply to these requests can be given with 'identity', 'password',
+and 'otp' commands. <id> needs to be copied from the the matching
+request. 'password' and 'otp' commands can be used regardless of
+whether the request was for PASSWORD or OTP. The main difference
+between these two commands is that values given with 'password' are
+remembered as long as wpa_supplicant is running whereas values given
+with 'otp' are used only once and then forgotten, i.e., wpa_supplicant
+will ask frontend for a new value for every use. This can be used to
+implement one-time-password lists and generic token card -based
+authentication.
+
+Example request for password and a matching reply:
+
+CTRL-REQ-PASSWORD-1:Password needed for SSID foobar
+> password 1 mysecretpassword
+
+Example request for generic token card challenge-response:
+
+CTRL-REQ-OTP-2:Challenge 1235663 needed for SSID foobar
+> otp 2 9876
+
+
+wpa_cli commands
+
+  status = get current WPA/EAPOL/EAP status
+  mib = get MIB variables (dot1x, dot11)
+  help = show this usage help
+  interface [ifname] = show interfaces/select interface
+  level <debug level> = change debug level
+  license = show full wpa_cli license
+  logoff = IEEE 802.1X EAPOL state machine logoff
+  logon = IEEE 802.1X EAPOL state machine logon
+  set = set variables (shows list of variables when run without arguments)
+  pmksa = show PMKSA cache
+  reassociate = force reassociation
+  reconfigure = force wpa_supplicant to re-read its configuration file
+  preauthenticate <BSSID> = force preauthentication
+  identity <network id> <identity> = configure identity for an SSID
+  password <network id> <password> = configure password for an SSID
+  otp <network id> <password> = configure one-time-password for an SSID
+  terminate = terminate wpa_supplicant
+  quit = exit wpa_cli
+
+
+
+Integrating with pcmcia-cs/cardmgr scripts
+------------------------------------------
+
+wpa_supplicant needs to be running when using a wireless network with
+WPA. It can be started either from system startup scripts or from
+pcmcia-cs/cardmgr scripts (when using PC Cards). WPA handshake must be
+completed before data frames can be exchanged, so wpa_supplicant
+should be started before DHCP client.
+
+Command line option '-w' can be used if wpa_supplicant is started
+before the wireless LAN interface is present (e.g., before inserting
+the PC Card) or is not yet up.
+
+For example, following small changes to pcmcia-cs scripts can be used
+to enable WPA support:
+
+Add MODE="Managed" and WPA="y" to the network scheme in
+/etc/pcmcia/wireless.opts.
+
+Add the following block to the end of 'start' action handler in
+/etc/pcmcia/wireless:
+
+    if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
+	/usr/local/bin/wpa_supplicant -Bw -c/etc/wpa_supplicant.conf \
+		-i$DEVICE
+    fi
+
+Add the following block to the end of 'stop' action handler (may need
+to be separated from other actions) in /etc/pcmcia/wireless:
+
+    if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
+	killall wpa_supplicant
+    fi
+
+This will make cardmgr start wpa_supplicant when the card is plugged
+in. wpa_supplicant will wait until the interface is set up--either
+when a static IP address is configured or when DHCP client is
+started--and will then negotiate keys with the AP.
+
+
+
+Optional integration with Xsupplicant
+-------------------------------------
+
+wpa_supplicant has an integrated IEEE 802.1X Supplicant that supports
+most commonly used EAP methods. In addition, wpa_supplicant has an
+experimental interface for integrating it with Xsupplicant
+(http://www.open1x.org/) for the WPA with EAP authentication.
+
+When using WPA-EAP, both wpa_supplicant and Xsupplicant must be
+configured with the network security policy. See Xsupplicant documents
+for information about its configuration. Please also note, that a new
+command line option -W (enable WPA) must be used when starting
+xsupplicant.
+
+Example configuration for xsupplicant:
+
+network_list = all
+default_netname = jkm
+
+jkm
+{
+	type = wireless
+	allow_types = eap_peap
+	identity = <BEGIN_ID>jkm<END_ID>
+	eap-peap {
+		random_file = /dev/urandom
+		root_cert = /home/jkm/CA.pem
+		chunk_size = 1398
+		allow_types = eap_mschapv2
+		eap-mschapv2 {
+			username = <BEGIN_UNAME>jkm<END_UNAME>
+			password = <BEGIN_PASS>jkm<END_PASS>
+		}
+	}
+}
+
+
+Example configuration for wpa_supplicant:
+
+network={
+	ssid="jkm"
+	key_mgmt=WPA-EAP
+}
+
+
+Both wpa_supplicant and xsupplicant need to be started. Please remember
+to add '-W' option for xsupplicant in order to provide keying material
+for wpa_supplicant and '-e' option for wpa_supplicant to disable internal
+IEEE 802.1X implementation.

+Developer notes for wpa_supplicant
+==================================
+
+The design goal for wpa_supplicant was to use hardware, driver, and OS
+independent, portable C code for all WPA functionality. All
+hardware/driver specific functionality is in separate files that
+implement a well-defined driver API.
+
+The goal of this file and the comments in the header files is to give
+enough information for other developers to be able to port the example
+code. If any information is missing, feel free to contact Jouni Malinen
+<jkmaline@cc.hut.fi> for more information. Contributions as patch files
+are also very welcome at the same address.
+
+Structure of the source code
+----------------------------
+
+Program initialization, main control loop and event handling is
+implemented in wpa_supplicant.c. WPA state machines and 4-Way/Group
+Key Handshake processing in in wpa.c. IEEE 802.1X/EAPOL processing and
+state machines are in eapol_sm.c. EAP state machine is in eap.c. EAP
+methods for the internal EAP peer are in eap_*.c.  Parser for the
+configuration file is implemented in config.c.
+
+Driver interface API is defined in driver.h and all hardware/driver
+dependent functionality is implemented in driver_*.c (see below).
+

+
+Driver wrapper implementation (driver.h, drivers.c)
+---------------------------------------------------
+
+All hardware and driver dependent functionality is implemented in as a
+separate C file(s) implementing defined wrapper functions. Other parts
+of the wpa_supplicant are designed to be hardware, driver, and operating
+system independent.
+
+Driver wrappers need to implement whatever calls are used in the
+target operating system/driver for controlling wireless LAN
+devices. As an example, in case of Linux, these are mostly some glue
+code and ioctl() calls and netlink message parsing for Linux Wireless
+Extensions. Since all features required for WPA are not yet included
+in Wireless Extensions, some driver specific code is used in the
+example implementation for Host AP driver. These driver dependent parts
+are to be replaced with generic code once the needed changes are
+included in the Wireless Extensions. After that, all Linux drivers, at
+least in theory, could use the same driver wrapper code.
+
+A driver wrapper needs to implement some or all of the functions
+defined in driver.h (see that file for detailed documentation of the
+functions). Hardware independent parts of wpa_supplicant will call
+these functions to control the driver/wlan card. In addition, support
+for driver events is required. The event callback function,
+wpa_supplicant_event(), and its parameters are documented in
+wpa_supplicant.h. In addition, pointer to the 'struct wpa_driver_ops'
+needs to be registered in drivers.c file.
+
+When porting to other operating systems, driver wrapper should be
+modified to use the native interface of the target OS. It is possible
+that some extra requirements for the interface between the driver
+wrapper and generic wpa_supplicant code are discovered during porting
+to a new operating system. These will be addresses on case by case
+basic by modifying the interface and updating the other driver
+wrappers for this. The goal is to avoid changing this interface
+without very good reasons in order to limit the number of changes
+needed to other wrappers and hardware independent parts of
+wpa_supplicant.
+
+Generic Linux Wireless Extensions functions are implemented in
+driver_wext.c. All Linux driver wrappers can use these when the kernel
+driver supports the generic ioctl()s and wireless events. Driver
+specific functions are implemented in separate C files, e.g.,
+driver_hostap.c. These files need to define struct wpa_driver_ops
+entry that will be used in wpa_supplicant.c when calling driver
+functions. These entries need to be added to the lists in
+wpa_supplicant_set_driver() and usage() functions in wpa_supplicant.c.
+
+In general, it is likely to be useful to first take a look at couple
+of the driver interfaces before starting on implementing a new
+one. driver_hostap.c and driver_wext.c include a complete
+implementation for Linux drivers that use wpa_supplicant-based control
+of WPA IE and roaming. driver_ndis.c (with help from driver_ndis_.c)
+is an example of a complete interface for Windows NDIS interface for
+drivers that generate WPA IE themselves and decide when to roam. These
+example implementations include full support for all security modes.
+
+
+Driver requirements for WPA
+---------------------------
+
+WPA introduces new requirements for the device driver. At least some
+of these need to be implemented in order to provide enough support for
+wpa_supplicant.
+
+TKIP/CCMP
+
+WPA requires that the pairwise cipher suite (encryption algorithm for
+unicast data packets) is TKIP or CCMP. These are new encryption
+protocols and thus, the driver will need to be modified to support
+them. Depending on the used wlan hardware, some parts of these may be
+implemented by the hardware/firmware.
+
+Specification for both TKIP and CCMP is available from IEEE (IEEE
+802.11i draft version 3.0). Fully functional, hardware independent
+implementation of both encryption protocols is also available in Host
+AP driver (driver/modules/hostap_{tkip,ccmp}.c).
+
+The driver will also need to provide configuration mechanism to allow
+user space programs to configure TKIP and CCMP. Current Linux Wireless
+Extensions (v16) does not yet support these algorithms or
+individual/non-default keys. Host AP driver has an example of private
+ioctl()s for this. Eventually, this should be replaced with modified
+Linux Wireless Extensions.
+
+Roaming control and scanning support
+
+wpa_supplicant controls AP selections based on the information
+received from Beacon and/or Probe Response frames. This means that the
+driver should support external control for scan process. In case of
+Linux, use of new Wireless Extensions scan support (i.e., 'iwlist
+wlan0 scan') is recommended. The current driver wrapper (driver_wext.c)
+uses this for scan results.
+
+Scan results must also include WPA information element. This is not
+yet defined in Linux Wireless Extensions and Host AP driver uses a
+custom event to provide the full WPA IE (including element id and
+length) as a hex string that is included in the scan results.
+Eventually, this should be defined as a Wireless Extensions ioctl
+that can be used both with scan results and with configuration of WPA IE
+for association request (and Beacon/Probe Response in case of an
+AP/IBSS).
+
+wpa_supplicant needs to also be able to request the driver to
+associate with a specific BSS. Current Host AP driver and matching
+driver_hostap.c wrapper uses following sequence for this
+request. Similar/identical mechanism should be usable also with other
+drivers.
+
+- set WPA IE for AssocReq with private ioctl
+- set SSID with SIOCSIWESSID
+- set channel/frequency with SIOCSIWFREQ
+- set BSSID with SIOCSIWAP
+  (this last ioctl will trigger the driver to request association)
+
+WPA IE generation
+
+wpa_supplicant selects which cipher suites and key management suites
+are used. Based on this information, it generates a WPA IE. This is
+provided to the driver interface in the associate call. This does not
+match with Windows NDIS drivers which generate the WPA IE
+themselves.
+
+wpa_supplicant allows Windows NDIS-like behavior by providing the
+selected cipher and key management suites in the associate call. If
+the driver generates its own WPA IE and that differs from the one
+generated by wpa_supplicant, the driver has to inform wpa_supplicant
+about the used WPA IE (i.e., the one it used in (Re)Associate
+Request). This notification is done using EVENT_ASSOCINFO event (see
+wpa_supplicant.h).
+
+Driver events
+
+wpa_supplicant needs to receive event callbacks when certain events
+occur (association, disassociation, Michael MIC failure, scan results
+available, PMKSA caching candidate). These events and the callback
+details are defined in wpa_supplicant.h.
+
+On Linux, association and disassociation can use existing Wireless
+Extensions event that is reporting new AP with SIOCGIWAP
+event. Similarly, completion of scan can be reported with SIOCGIWSCAN
+event.
+
+Michael MIC failure event is not yet included in Wireless Extensions,
+so this needs a custom event. Host AP driver uses custom event with
+following contents: MLME-MICHAELMICFAILURE.indication(keyid=#
+broadcast/unicast addr=addr2). This is the recommended format until
+the event is added to Linux Wireless Extensions.

+Automatic regression and interoperability testing of wpa_supplicant's
+IEEE 802.1X/EAPOL authentication
+
+Test program:
+- Linked some parts of IEEE 802.1X Authenticator implementation from
+  hostapd (RADIUS client and RADIUS processing, EAP<->RADIUS
+  encapsulation/decapsulation) into wpa_supplicant.
+- Replaced wpa_supplicant.c and wpa.c with test code that trigger
+  IEEE 802.1X authentication automatically without need for wireless
+  client card or AP.
+- For EAP methods that generate keying material, the key derived by the
+  Supplicant is verified to match with the one received by the (now
+  integrated) Authenticator.
+
+The full automated test suite can now be run in couple of seconds, but
+I'm more than willing to add new RADIUS authentication servers to make
+this take a bit more time.. ;-) As an extra bonus, this can also be
+seen as automatic regression/interoperability testing for the RADIUS
+server, too.
+
+In order for me to be able to use a new authentication server, the
+server need to be available from Internet (at least from one static IP
+address) and I will need to get suitable user name/password pairs,
+certificates, and private keys for testing use. Other alternative
+would be to get an evaluation version of the server so that I can
+install it on my own test setup. If you are interested in providing
+either server access or evaluation version, please contact me
+(jkmaline@cc.hut.fi).

+2) used FreeRADIUS as inner auth server
+3) required a patch to FreeRADIUS to fix EAP-SIM
+5) PEAPv1 required termination of negotiation on tunneled EAP-Success and new
+   label in key deriviation
+   (phase1="peap_outer_success=0 peaplabel=1") (in "IETF Draft 5" mode)
+6) Authenticator simulator required patching for handling Access-Accept within

+   rlm_eap_psk implementation from
+   http://perso.rd.francetelecom.fr/bersani/EAP_PSK/
+	EAP-PSKWindowsimplementations.html
+8) PEAPv1 used non-standard version negotiation (client had to force v1 even

+This is a quick hack for testing EAP-FAST with openssl.
+
+Addition of TLS extensions to ClientHello/ServerHello is more or less
+ok, though not very clean in the way that the caller needs to take
+care of constructing set of all extensions. In addition there is not
+mechanism for reading the TLS extensions, i.e., this would not be
+enough for EAP-FAST authenticator.
+
+Rest of the changes are obviously ugly and/or incorrect for most
+parts, but it demonstrates the minimum set of changes to skip some of
+the error cases that prevented completion of TLS handshake without
+certificates. In other words, this is just a proof-of-concept type of
+example to make it possible to experiment with EAP-FAST. Cleaner patch
+for the needed functionality would be welcome..

+SHA-1 in C

+100% Public Domain
+
+-----------------
+Modified 7/98 
+By James H. Brown <jbrown@burgoyne.com>
+Still 100% Public Domain
+
+Corrected a problem which generated improper hash values on 16 bit machines
+Routine SHA1Update changed from
+	void SHA1Update(SHA1_CTX* context, unsigned char* data, unsigned int
+len)
+to
+	void SHA1Update(SHA1_CTX* context, unsigned char* data, unsigned
+long len)
+
+The 'len' parameter was declared an int which works fine on 32 bit machines.
+However, on 16 bit machines an int is too small for the shifts being done
+against
+it.  This caused the hash function to generate incorrect values if len was
+greater than 8191 (8K - 1) due to the 'len << 3' on line 3 of SHA1Update().
+
+Since the file IO in main() reads 16K at a time, any file 8K or larger would
+be guaranteed to generate the wrong hash (e.g. Test Vector #3, a million
+"a"s).
+
+I also changed the declaration of variables i & j in SHA1Update to 
+unsigned long from unsigned int for the same reason.
+
+These changes should make no difference to any 32 bit implementations since
+an
+int and a long are the same size in those environments.
+
+--
+I also corrected a few compiler warnings generated by Borland C.
+1. Added #include <process.h> for exit() prototype
+2. Removed unused variable 'j' in SHA1Final
+3. Changed exit(0) to return(0) at end of main.
+
+ALL changes I made can be located by searching for comments containing 'JHB'

+To do:
+- add WPA support to Linux Wireless Extensions
+- add support for other drivers
+- implement GUI for WPA Supplicant/Xsupplicant/iwconfig/iwlist
+  (easy to use configuration and network stats, etc.)
+- add support for opportunistic PMKSA caching
+- hostap: try other roaming modes
+  NOTE: current mode (manual roaming) does not really roam at all..
+  Firmware did not notice the current AP disappearing..
+- EAP-MSCHAPv2: add support for password changing
+- add support for WPA with ap_scan=0 (update selected cipher etc. based on
+  AssocInfo; make sure these match with configuration)
+- add driver interface for using wpa_supplicant with wired interface
+  (or a separate program using EAPOL library)
+- wpa_supplicant.conf g+rw so that frontend can change wpa_supplicant.conf
+  and RECONFIG wpa_supplicant  (?)
+	(or wpa_supplicant changes .conf and ctrl interface gets support for
+	changing config?)
+- optional security separation (build time option): run EAPOL state machines
+  as non-root (need to add something like socketpair between privileged root
+  process and non-root handler; send EAPOL packets between processes
+  and send keying data from non-root -> privileged)
+  EAPOL-Key processing (WPA & WEP keys) could be in privileged part
+  at least in the beginning; some parts might end up being moved to
+  non-root part eventually
+- consider closing smart card / PCSC connection when EAP-SIM/EAP-AKA
+  authentication has been completed (cache scard data based on serial#(?)
+  and try to optimize next connection if the same card is present for next
+  auth)
+- EAP-AKA: AT_CHECKCODE
+- EAP-SIM/AKA: AT_RESULT_IND
+- abort auth if EAP method initialization fails and there no other
+  accepted methods (i.e., do not send NAK for the same method that just
+  failed)
+- on disconnect event, could try to associate with another AP if one is
+  present in scan results; would need to update scan results periodically..
+- add flag scan_requested and only try to re-associate if this is set when
+  new scan results are received; this would allow background scans without
+  triggering re-assoc..
+- if driver/hw is not WPA2 capable, must remove WPA_PROTO_RSN flag from
+  ssid->proto fields to avoid detecting downgrade attacks when the driver
+  is not reporting RSN IE, but msg 3/4 has one
+- read CA certs from PFX file
+- EAP-SIM/AKA: if SIM reader initialization fails, do not start authentication
+- Cisco AP and non-zero keyidx for unicast -> map to broadcast
+  (actually, this already works with driver_ndis; so maybe just change
+  driver_*.c to do the mapping for drivers that cannot handle non-zero keyidx
+  for unicast)
+- IEEE 802.1X and key update with driver_ndis?? wpa_supplicant did not seem
+  to see unencrypted EAPOL-Key frames at all..
+- update developer.txt to match with current implementation
+  (driver API updates, EAP methods)
+- driver_wext.c and driver that does not support WPA -> fix plaintext, WEP, and
+  IEEE 802.1X operation (e.g., use capabilities to report no support for WPA)

+##### Example wpa_supplicant configuration file ###############################
+# Empty lines and lines starting with # are ignored
+
+# NOTE! This file may contain password information and should probably be made
+# readable only by root user on multiuser systems.
+
+# global configuration (shared by all network blocks)
+#
+# Interface for separate control program. If this is specified, wpa_supplicant
+# will create this directory and a UNIX domain socket for listening to requests
+# from external programs (CLI/GUI, etc.) for status information and
+# configuration. The socket file will be named based on the interface name, so
+# multiple wpa_supplicant processes can be run at the same time if more than
+# one interface is used.
+# /var/run/wpa_supplicant is the recommended directory for sockets and by
+# default, wpa_cli will use it when trying to connect with wpa_supplicant.
+ctrl_interface=/var/run/wpa_supplicant
+
+# Access control for the control interface can be configured by setting the
+# directory to allow only members of a group to use sockets. This way, it is
+# possible to run wpa_supplicant as root (since it needs to change network
+# configuration and open raw sockets) and still allow GUI/CLI components to be
+# run as non-root users. However, since the control interface can be used to
+# change the network configuration, this access needs to be protected in many
+# cases. By default, wpa_supplicant is configured to use gid 0 (root). If you
+# want to allow non-root users to use the control interface, add a new group
+# and change this value to match with that group. Add users that should have
+# control interface access to this group. If this variable is commented out or
+# not included in the configuration file, group will not be changed from the
+# value it got by default when the directory or socket was created.
+#
+# This variable can be a group name or gid.
+#ctrl_interface_group=wheel
+ctrl_interface_group=0
+
+# IEEE 802.1X/EAPOL version
+# wpa_supplicant was implemented based on IEEE 802-1X-REV-d8 which defines
+# EAPOL version 2. However, there are many APs that do not handle the new
+# version number correctly (they seem to drop the frames completely). In order
+# to make wpa_supplicant interoperate with these APs, the version number is set
+# to 1 by default. This configuration value can be used to set it to the new
+# version (2).
+eapol_version=1
+
+# AP scanning/selection
+# By default, wpa_supplicant requests driver to perform AP scanning and then
+# uses the scan results to select a suitable AP. Another alternative is to
+# allow the driver to take care of AP scanning and selection and use
+# wpa_supplicant just to process EAPOL frames based on IEEE 802.11 association
+# information from the driver.
+# 1: wpa_supplicant initiates scanning and AP selection
+# 0: driver takes care of scanning, AP selection, and IEEE 802.11 association
+#    parameters (e.g., WPA IE generation); this mode can also be used with
+#    non-WPA drivers when using IEEE 802.1X mode; do not try to associate with
+#    APs (i.e., external program needs to control association)
+# 2: like 0, but associate with APs using security policy and SSID (but not
+#    BSSID); this can be used, e.g., with ndiswrapper and NDIS driver to
+#    enable operation with hidden SSIDs and optimized roaming; in this mode,
+#    only the first network block in the configuration file is used and this
+#    configuration should have explicit security policy (i.e., only one option
+#    in the lists) for key_mgmt, pairwise, group, proto variables
+ap_scan=1
+
+# EAP fast re-authentication
+# By default, fast re-authentication is enabled for all EAP methods that
+# support it. This variable can be used to disable fast re-authentication.
+# Normally, there is no need to disable this.
+fast_reauth=1
+
+# network block
+#
+# Each network (usually AP's sharing the same SSID) is configured as a separate
+# block in this configuration file. The network blocks are in preference order
+# (the first match is used).
+#
+# network block fields:
+#
+# ssid: SSID (mandatory); either as an ASCII string with double quotation or
+#	as hex string; network name
+#
+# scan_ssid:
+#	0 = do not scan this SSID with specific Probe Request frames (default)
+#	1 = scan with SSID-specific Probe Request frames (this can be used to
+#	    find APs that do not accept broadcast SSID or use multiple SSIDs;
+#	    this will add latency to scanning, so enable this only when needed)
+#
+# bssid: BSSID (optional); if set, this network block is used only when
+#	associating with the AP using the configured BSSID
+#
+# priority: priority group (integer)
+# By default, all networks will get same priority group (0). If some of the
+# networks are more desirable, this field can be used to change the order in
+# which wpa_supplicant goes through the networks when selecting a BSS. The
+# priority groups will be iterated in decreasing priority (i.e., the larger the
+# priority value, the sooner the network is matched against the scan results).
+# Within each priority group, networks will be selected based on security
+# policy, signal strength, etc.
+# Please note that AP scanning with scan_ssid=1 is not using this priority to
+# select the order for scanning. Instead, it uses the order the networks are in
+# the configuration file.
+#
+# mode: IEEE 802.11 operation mode
+# 0 = infrastructure (Managed) mode, i.e., associate with an AP (default)
+# 1 = IBSS (ad-hoc, peer-to-peer)
+# Note: IBSS can only be used with key_mgmt NONE (plaintext and static WEP)

+# to be set to 2 for IBSS. WPA-None requires following network block options:

+# subject_match: Substring to be matched against the subject of the

+#	The subject string is in following format:
+#	/C=US/ST=CA/L=San Francisco/CN=Test AS/emailAddress=as@example.com
+# phase1: Phase1 (outer authentication, i.e., TLS tunnel) parameters
+#	(string with field-value pairs, e.g., "peapver=0" or
+#	"peapver=1 peaplabel=1")
+#	'peapver' can be used to force which PEAP version (0 or 1) is used.
+#	'peaplabel=1' can be used to force new label, "client PEAP encryption",
+#	to be used during key derivation when PEAPv1 or newer. Most existing
+#	PEAPv1 implementation seem to be using the old label, "client EAP
+#	encryption", and wpa_supplicant is now using that as the default value.
+#	Some servers, e.g., Radiator, may require peaplabel=1 configuration to
+#	interoperate with PEAPv1; see eap_testing.txt for more details.
+#	'peap_outer_success=0' can be used to terminate PEAP authentication on
