-                    GNU GENERAL PUBLIC LICENSE
-                       Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
- 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 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 Lesser 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) <year>  <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.,
-    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 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) year 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
-  Ty Coon, President of Vice
-
-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 Lesser General
-Public License instead of this License.

-=== NCR API ===
-
-This is the linux-cryptodev NCR branch. The ioctl() API is in ncr.h.
-
-For the new API to fully operate, root must load a system key (constant
-per system) using the ncr-setkey program. After this stage the new API should
-be fully operational. Example:
-$ dd if=/dev/urandom of=/boot/key count=1 bs=16
-$ chmod 600 /boot/key
-$ userspace/ncr-setkey /boot/key
-
-The main concept of the new API is disallow userspace applications
-access to cryptographic keys. Operations are possible (such as
-encryption/decryption/signing/verifying), but raw access to the
-keys is not be possible.
-
-
-=== OpenBSD crypto compatibility ===
-
-A compatibility API using OpenBSD's interface via /dev/crypto device driver 
-is supported. This enables access to kernel space cipher implementations
-and hardware accelerators.

-.TH CRYPTO 4 2010-08-20 Linux "Linux Programmer's Manual"
-
-.SH NAME
-/dev/crypto \- kernel cryptographic module interface
-
-.SH SYNOPSIS
-
-.B #include <ncr.h>
-.br
-.B int fd = open("/dev/crypto", O_RDWR);
-.br
-.B int res = ioctl(fd, \fINCRIO...\fP, &\fIdata\fP);
-
-.SH DESCRIPTION
-The
-.I /dev/crypto
-device file provides an
-.BR ioctl (2)
-interface to the kernel-space crypto implementation.
-
-Each
-.BR open (2)
-of the
-.I /dev/crypto
-file establishes a separate namespace within which crypto operations work.
-The namespace can be shared across threads and processes
-by sharing the open file description.
-Last close of the open file description automatically destroys all objects
-allocated within the namespace.
-
-All
-.BR ioctl (2)s
-have the same form:
-The user sets up a data structure with input data,
-and passes a pointer to the data structure as the third parameter to
-.BR ioctl (2).
-On success, output data is available in the same structure.
-
-.SH OPERATION ATTRIBUTES
-
-In addition to the fixed members of data structures,
-a process can pass additional attributes on input of most operations,
-and receive additional attributes back from the kernel.
-If this is supported by a specific operation,
-the fixed data structure members for this operation include
-.B input_size
-and \fBoutput_size\fR.
-
-The input attributes immediately follow the fixed data structure as a sequence
-of correctly aligned (\fBstruct nlattr\fP, attribute data) pairs,
-using the same data layout and formatting rules as
-.BR netlink (7)
-messages.
-The
-.B input_size
-member must be initialized to the total length of input (including both the
-fixed data structure and the attributes).
-
-There is an (unspecified) upper limit on the total size of all attributes,
-which should be large enough to accommodate any reasonable application.
-If a larger input is provided nevertheless,
-the operation will fail with \fBEOVERFLOW\fP.
-
-Output attributes, if any, are written by the kernel in the same format
-following the fixed data structure (overwriting input attributes, if any).
-The
-.B output_size
-member must be initialized to the total space available for output
-(including the fixed data structure and space for attributes),
-and is updated by the kernel with the total space actually used for attributes.
-
-If the space available for output attributes is too small,
-the operation will fail with \fBERANGE\fP.
-
-As a special case,
-.B input_size
-may be zero to indicate no input attributes are supplied.
-Similarly,
-.B output_size
-may be zero to indicate no space for output attributes is provided;
-in such case
-.B output_size
-is not overwritten by the kernel with the total space actually used
-(which is equal to size of the fixed data structure)
-and remains zero when the operation finishes.
-
-The kernel accepts and silently ignores unknown attributes.
-
-The kernel will not add new output attributes to existing operations
-in future releases
-unless the new output attribute was explicitly requested by the application.
-(Therefore, the application does not have to allocate any extra space for
-output attributes it does not expect.)
-
-The following attributes are used in more than one operation:
-
-.TP
-.B NCR_ATTR_ALGORITHM
-A NUL-terminated string specifying an algorithm
-(to be used in an operation, or as a property of a key),
-using the Linux crypto API algorithm names.
-
-Three additional algorithm names are recognized: \fBrsa\fP, \fBdsa\fP, \fBdh\fP.
-
-.TP
-.B NCR_ATTR_IV
-Unformatted binary data specifying an initialization vector,
-
-.TP
-.B NCR_ATTR_KEY_FLAGS
-An 32-bit unsigned integer in native byte order specifying key flags,
-a combination of
-.B NCR_KEY_FLAG_EXPORTABLE
-(the key material can be exported in plaintext to user space)
-and
-.B NCR_KEY_FLAG_WRAPPABLE
-(the key material can be wrapped and the result made available to user space).
-
-.TP
-.B NCR_ATTR_KEY_ID
-Arbitrary binary data
-which can be used by the application for key identification.
-
-.TP
-.B NCR_ATTR_KEY_TYPE
-An 32-bit unsigned integer in native byte order specifying key type,
-one of \fBNCR_KEY_TYPE_SECRET\fP, \fBNCR_KEY_TYPE_PUBLIC\fP and
-\fBNCR_KEY_TYPE_PRIVATE\fP.
-
-.TP
-.B NCR_ATTR_WRAPPING_ALGORITHM
-A NUL-terminated string specifying a key wrapping algorithm.
-The values
-.B walg-aes-rfc3394
-and
-.B walg-aes-rfc5649
-are currently supported.
-.RE
-
-.SH OPERATIONS
-
-The following operations are defined:
-
-.TP
-.B NCRIO_KEY_INIT
-Allocate a kernel-space key object.
-The third
-.BR ioctl (s)
-parameter is ignored
-(key attributes are set later, when the key material is initialized).
-Returns an
-.B ncr_key_t
-descriptor for the key object
-(valid within the current
-.I /dev/crypto
-namespace)
-on success.
-
-There is a per-process and per-user (not per-namespace) limit
-on the number key objects that can be allocated.
-
-.TP
-.B NCRIO_KEY_DEINIT
-Deallocate a kernel-space key object.
-The parameter points to a
-.B ncr_key_t
-descriptor of the key object.
-After all other operations using this key object (if any) terminate,
-the key material will be cleared and the object will be freed.
-Note that this may happen both before this operation returns,
-and after it returns, depending on other references to this key object.
-
-.TP
-.B NCRIO_KEY_GENERATE
-Clear existing key material in the specified key object,
-and generate new key material.
-
-The parameter points to \fBstruct ncr_key_generate\fP,
-which specifies the destination key object in its
-.B key
-member.
-
-The following input attributes are recognized:
-
-.RS
-.IP \fBNCR_ATTR_ALGORITHM\fP
-Mandatory.
-.IP \fBNCR_ATTR_KEY_FLAGS\fP
-Optional, flags are unchanged if not present.
-.IP \fBNCR_ATTR_SECRET_KEY_BITS\fP
-Mandatory for symmetric keys.
-An 32-bit unsigned integer in native byte order specifying key length in bits.
-.RE
-
-.IP
-Only symmetric keys can be currently generated using this operation.
-
-In addition to generating the key material,
-the "persistent" key ID is reset to a random value.
-
-.TP
-.B NCRIO_KEY_GENERATE_PAIR
-Similar to \fBNCRIO_KEY_GENERATE\fP,
-except that a pair of public/private keys is generated.
