+		    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.

+
+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.

+Utilities for aufs2
+http://aufs.sf.net
+J. R. Okajima
+
+These utilities are always necessary for aufs2.
+If you forget to install them, your aufs may not work correctly.
+And these are not for aufs1 essentially, except aubrsync. See below in
+detail.
+
+Makefile in this tree has some customizable make-variables.
+- KDIR
+  specify your kernel source path if necessary
+- DESTDIR
+  specify your install path if necessary.
+  some commands have to be installed under /sbin.
+
+o /sbin/mount.aufs, /sbin/umount.aufs
+  Helpers for util-linux-ng package. You should NOT invoke them
+  manually. Just install them by "make install".
+
+o /sbin/auplink
+  Handles aufs pseudo-link at remount/unmount time. You can invoke it
+  manually at anytime.
+
+o /usr/bin/auchk
+  Similar to generic fsck. Checks whether a branch is healthy or not
+  from aufs's point of view.
+
+o /usr/bin/aubrsync
+  Move files from the upper writable branch to the lower branch.
+  If you use this script with aufs1, then you need to install aufs.shlib
+  to /usr/lib/aufs.shlib. Currently only the 20080211 version is tested
+  for aufs1.
+  The development of this script is sponcered by ASUSTek Computer Inc.
+  (http://www.asus.com/).
+  Kindly they agreed that I keep my aufs work as free software as it has
+  been.
+
+o /etc/default/aufs
+  A library for shell scripts.

+	'move_with_wh' is a simple variation of 'move' which moves
+	whiteouts separately before the actual 'move'.
+
+	If you execute this script under linux-2.6.24 or earlier, the

+	  branch. This operation is for aufs which has only 2 branches,
+	  and mainly for a system shutdown script.
+	  All files on the upper branch remain.
+
+	  $ sudo $me copy /your/aufs /your/upper_branch /your/lower_branch
+
+	- Like above (2 branches), move and reflect all modifications
+	  from upper to lower. Almost all files on the upper branch will
+	  be removed. You can still use this aufs after the
+	  operation. But the inode number may be changed. If your
+	  application which depends upon the inode number was running at
+	  that time, it may not work correctly.

+.SH NAME
+aufs \- advanced multi layered unification filesystem. version \*[AUFS_VERSION]
+
+.\" ----------------------------------------------------------------------
+.SH DESCRIPTION
+Aufs is a stackable unification filesystem such as Unionfs, which unifies
+several directories and provides a merged single directory.
+In the early days, aufs was entirely re-designed and re-implemented
+Unionfs Version 1.x series. After
+many original ideas, approaches and improvements, it
+becomes totally different from Unionfs while keeping the basic features.
+See Unionfs Version 1.x series for the basic features.
+Recently, Unionfs Version 2.x series begin taking some of same
+approaches to aufs's.
+
+.\" ----------------------------------------------------------------------

+.RE
+.
+.TP
+.B br:BRANCH[:BRANCH ...] (dirs=BRANCH[:BRANCH ...])
+Adds new branches.
+(cf. Branch Syntax).
+
+Aufs rejects the branch which is an ancestor or a descendant of another
+branch. It is called overlapped. When the branch is loopback-mounted
+directory, aufs also checks the source fs-image file of loopback
+device. If the source file is a descendant of another branch, it will
+be rejected too.
+
+After mounting aufs or adding a branch, if you move a branch under
+another branch and make it descendant of another branch, aufs will not
+work correctly.
+.
+.TP
+.B [ add | ins ]:index:BRANCH
+Adds a new branch.
+The index begins with 0.
+Aufs creates
+whiteout-base(\*[AUFS_WH_BASE]) and
+whplink-dir(\*[AUFS_WH_PLINKDIR]) if necessary.
+
+If there is the same named file on the lower branch (larger index),
+aufs will hide the lower file.
+You can only see the highest file.
+You will be confused if the added branch has whiteouts (including
+diropq), they may or may not hide the lower entries.
+.\" It is recommended to make sure that the added branch has no whiteout.
+
+Even if a process have once mapped a file by mmap(2) with MAP_SHARED
+and the same named file exists on the lower branch,
+the process still refers the file on the lower(hidden)
+branch after adding the branch.
+If you want to update the contents of a process address space after
+adding, you need to restart your process or open/mmap the file again.
+.\" Usually, such files are executables or shared libraries.
+(cf. Branch Syntax).
+.
+.TP
+.B del:dir
+Removes a branch.
+Aufs does not remove
+whiteout-base(\*[AUFS_WH_BASE]) and
+whplink-dir(\*[AUFS_WH_PLINKDIR]) automatically.
+For example, when you add a RO branch which was unified as RW, you
+will see whiteout-base or whplink-dir on the added RO branch.
+
+If a process is referencing the file/directory on the deleting branch
+(by open, mmap, current working directory, etc.), aufs will return an
+error EBUSY.
+.
+.TP
+.B mod:BRANCH
+Modifies the permission flags of the branch.
+Aufs creates or removes
+whiteout-base(\*[AUFS_WH_BASE]) and/or
+whplink-dir(\*[AUFS_WH_PLINKDIR]) if necessary.
+
+If the branch permission is been changing `rw' to `ro', and a process
+is mapping a file by mmap(2)
+.\" with MAP_SHARED
+on the branch, the process may or may not
+be able to modify its mapped memory region after modifying branch
+permission flags.
+Additioanlly when you enable CONFIG_IMA (in linux-2.6.30 and later), IMA
+may produce some wrong messages. But this is equivalent when the
+filesystem is changed `ro' in emergency.
+(cf. Branch Syntax).
+.
+.TP
+.B append:BRANCH
+equivalent to `add:(last index + 1):BRANCH'.
+(cf. Branch Syntax).
+.
+.TP
+.B prepend:BRANCH
+equivalent to `add:0:BRANCH.'
+(cf. Branch Syntax).
+.
+.TP
+.B xino=filename
+Use external inode number bitmap and translation table.
+When CONFIG_AUFS_EXPORT is enabled, external inode generation table too.
+It is set to
+<FirstWritableBranch>/\*[AUFS_XINO_FNAME] by default, or
+\*[AUFS_XINO_DEFPATH].
+Comma character in filename is not allowed.
+
+The files are created per an aufs and per a branch filesystem, and
+unlinked. So you
+cannot find this file, but it exists and is read/written frequently by
+aufs.
+(cf. External Inode Number Bitmap, Translation Table and Generation Table).
+
+If you enable CONFIG_SYSFS, the path of xino files are not shown in
+/proc/mounts (and /etc/mtab), instead it is shown in
+<sysfs>/fs/aufs/si_<id>/xi_path.
+Otherwise, it is shown in /proc/mounts unless it is not the default
+path.
+.
+.TP
+.B noxino
+Stop using external inode number bitmap and translation table.
+
+If you use this option,
+Some applications will not work correctly.
+.\" And pseudo link feature will not work after the inode cache is
+.\" shrunk.
+(cf. External Inode Number Bitmap, Translation Table and Generation Table).
+.
+.TP
+.B trunc_xib
+Truncate the external inode number bitmap file. The truncation is done
+automatically when you delete a branch unless you do not specify
+`notrunc_xib' option.
+(cf. External Inode Number Bitmap, Translation Table and Generation Table).
+.
+.TP
+.B notrunc_xib
+Stop truncating the external inode number bitmap file when you delete
+a branch.
+(cf. External Inode Number Bitmap, Translation Table and Generation Table).
+.
+.TP
+.B create_policy | create=CREATE_POLICY
+.TQ
+.B copyup_policy | copyup | cpup=COPYUP_POLICY
+Policies to select one among multiple writable branches. The default
+values are `create=tdp' and `cpup=tdp'.
+link(2) and rename(2) systemcalls have an exception. In aufs, they
+try keeping their operations in the branch where the source exists.
+(cf. Policies to Select One among Multiple Writable Branches).
+.
+.TP
+.B verbose | v
+Print some information.
+Currently, it is only busy file (or inode) at deleting a branch.
+.
+.TP
+.B noverbose | quiet | q | silent
+Disable `verbose' option.
+This is default value.
+.
+.TP
+.B sum
+df(1)/statfs(2) returns the total number of blocks and inodes of
+all branches.
+Note that there are cases that systemcalls may return ENOSPC, even if
+df(1)/statfs(2) shows that aufs has some free space/inode.
+.
+.TP
+.B nosum
+Disable `sum' option.
+This is default value.
+.
+.TP
+.B dirwh=N
+Watermark to remove a dir actually at rmdir(2) and rename(2).
+
+If the target dir which is being removed or renamed (destination dir)
+has a huge number of whiteouts, i.e. the dir is empty logically but
+physically, the cost to remove/rename the single
+dir may be very high.
+It is
+required to unlink all of whiteouts internally before issuing
+rmdir/rename to the branch.
+To reduce the cost of single systemcall,
+aufs renames the target dir to a whiteout-ed temporary name and
+invokes a pre-created
+kernel thread to remove whiteout-ed children and the target dir.
+The rmdir/rename systemcall returns just after kicking the thread.
+
+When the number of whiteout-ed children is less than the value of
+dirwh, aufs remove them in a single systemcall instead of passing
+another thread.
+This value is ignored when the branch is NFS.
+The default value is \*[AUFS_DIRWH_DEF].
+.\" .
+.\" .TP
+.\" .B rdcache=N
+.
+.TP
+.B rdblk=N
+Specifies a size of internal VDIR block which is allocated at a time in
+byte.
+The VDIR block will be allocated several times when necessary. If your
+directory has millions of files, you may want to expand this size.
+The default value is defined as \*[AUFS_RDBLK_DEF].
+The size has to be lager than NAME_MAX (usually 255) and kmalloc\-able
+(the maximum limit depends on your system. at least 128KB is available
+for every system).
+Whenever you can reset the value to default by specifying rdblk=def.
+(cf. Virtual or Vertical Directory Block).
+.
+.TP
+.B rdhash=N
+Specifies a size of internal VDIR hash table which is used to compare
+the file names under the same named directory on multiple branches.
+The VDIR hash table will be allocated in readdir(3)/getdents(2),
+rmdir(2) and rename(2) for the existing target directory. If your
+directory has millions of files, you may want to expand this size.
+The default value is defined as \*[AUFS_RDHASH_DEF].
+The size has to be lager than zero, and it will be multiplied by 4 or 8
+(for 32\-bit and 64\-bit respectively, currently). The result must be
+kmalloc\-able
+(the maximum limit depends on your system. at least 128KB is available
+for every system).
+Whenever you can reset the value to default by specifying rdhash=def.
+(cf. Virtual or Vertical Directory Block).
+.
+.TP
+.B plink
+.TQ
+.B noplink
+Specifies to use `pseudo link' feature or not.
+The default is `plink' which means use this feature.
+(cf. Pseudo Link)
+.
+.TP
+.B clean_plink
+Removes all pseudo-links in memory.
+In order to make pseudo-link permanent, use
+`auplink' utility just before one of these operations,
+unmounting aufs,
+using `ro' or `noplink' mount option,
+deleting a branch from aufs,
+adding a branch into aufs,
+or changing your writable branch as readonly.
+If you installed both of /sbin/mount.aufs and /sbin/umount.aufs, and your
+mount(8) and umount(8) support them,
+`auplink' utility will be executed automatically and flush pseudo-links.
+(cf. Pseudo Link)
+.
+.TP
+.B udba=none | reval | inotify
+Specifies the level of UDBA (User's Direct Branch Access) test.
+(cf. User's Direct Branch Access and Inotify Limitation).
+.
+.TP
+.B diropq=whiteouted | w | always | a
+Specifies whether mkdir(2) and rename(2) dir case make the created directory
+`opaque' or not.
+In other words, to create `\*[AUFS_WH_DIROPQ]' under the created or renamed
+directory, or not to create.
+When you specify diropq=w or diropq=whiteouted, aufs will not create
+it if the
+directory was not whiteouted or opaqued. If the directory was whiteouted
+or opaqued, the created or renamed directory will be opaque.
+When you specify diropq=a or diropq==always, aufs will always create
+it regardless
+the directory was whiteouted/opaqued or not.
+The default value is diropq=w, it means not to create when it is unnecessary.
+If you define CONFIG_AUFS_COMPAT at aufs compiling time, the default will be
+diropq=a.
+You need to consider this option if you are planning to add a branch later
+since `diropq' affects the same named directory on the added branch.
+.
+.TP
+.B warn_perm
+.TQ
+.B nowarn_perm
+Adding a branch, aufs will issue a warning about uid/gid/permission of
+the adding branch directory,
+when they differ from the existing branch's. This difference may or
+may not impose a security risk.
+If you are sure that there is no problem and want to stop the warning,
+use `nowarn_perm' option.
+The default is `warn_perm' (cf. DIAGNOSTICS).
+.
+.TP
+.B shwh
+.TQ
+.B noshwh
+By default (noshwh), aufs doesn't show the whiteouts and
+they just hide the same named entries in the lower branches. The
+whiteout itself also never be appeared.
+If you enable CONFIG_AUFS_SHWH and specify `shwh' option, aufs
+will show you the name of whiteouts
+with keeping its feature to hide the lowers.
+Honestly speaking, I am rather confused with this `visible whiteouts.'
+But a user who originally requested this feature wrote a nice how-to
+document about this feature. See Tips file in the aufs CVS tree.
+
+.\" ----------------------------------------------------------------------
+.SH Module Parameters
+.TP
+.B nwkq=N
+The number of kernel thread named \*[AUFS_WKQ_NAME].
+
+Those threads stay in the system while the aufs module is loaded,
+and handle the special I/O requests from aufs.
+The default value is \*[AUFS_NWKQ_DEF].
+
+The special I/O requests from aufs include a part of copy-up, lookup,
+directory handling, pseudo-link, xino file operations and the
+delegated access to branches.
+For example, Unix filesystems allow you to rmdir(2) which has no write
+permission bit, if its parent directory has write permission bit. In aufs, the
+removing directory may or may not have whiteout or `dir opaque' mark as its
+child. And aufs needs to unlink(2) them before rmdir(2).
+Therefore aufs delegates the actual unlink(2) and rmdir(2) to another kernel
+thread which has been created already and has a superuser privilege.
+
+If you enable CONFIG_SYSFS, you can check this value through
+<sysfs>/module/aufs/parameters/nwkq.
+
+.
+.TP
+.B brs=1 | 0
+Specifies to use the branch path data file under sysfs or not.
+
+If the number of your branches is large or their path is long
+and you meet the limitation of mount(8) ro /etc/mtab, you need to
+enable CONFIG_SYSFS and set aufs module parameter brs=1.
+
+When this parameter is set as 1, aufs does not show `br:' (or dirs=)
+mount option through /proc/mounts (and /etc/mtab). So you can
+keep yourself from the page limitation of
+mount(8) or /etc/mtab.
+Aufs shows branch paths through <sysfs>/fs/aufs/si_XXX/brNNN.
+Actually the file under sysfs has also a size limitation, but I don't
+think it is harmful.
+
+There is one more side effect in setting 1 to this parameter.
+If you rename your branch, the branch path written in /etc/mtab will be
+obsoleted and the future remount will meet some error due to the
+unmatched parameters (Remember that mount(8) may take the options from
+/etc/mtab and pass them to the systemcall).
+If you set 1, /etc/mtab will not hold the branch path and you will not
+meet such trouble. On the other hand, the entries for the
+branch path under sysfs are generated dynamically. So it must not be obsoleted.
+But I don't think users want to rename branches so often.
+
+If CONFIG_SYSFS is disable, this parameter is always set to 0.
+.
+.TP
+.B sysrq=key
+Specifies MagicSysRq key for debugging aufs.
+You need to enable both of CONFIG_MAGIC_SYSRQ and CONFIG_AUFS_DEBUG.
+Currently this is for developers only.
+The default is `a'.
+.
+.TP
+.B debug= 0 | 1
+Specifies disable(0) or enable(1) debug print in aufs.
+This parameter can be changed dynamically.
+You need to enable CONFIG_AUFS_DEBUG.
+Currently this is for developers only.
+The default is `0' (disable).

+dir_path is a directory path.
+The keyword after `dir_path=' is a
+permission flags for that branch.
+Comma, colon and the permission flags string (including `=')in the path

+
+Any filesystem can be a branch, But some are not accepted such like
+sysfs, procfs and unionfs.
+If you specify such filesystems as an aufs branch, aufs will return an error
+saying it is unsupported.
+
+Cramfs in linux stable release has strange inodes and it makes aufs
+confused. For example,
+.nf

+
+All these two directories and two files have the same inode with one
+as their link count. Aufs cannot handle such inode correctly.
+Currently, aufs involves a tiny workaround for such inodes. But some
+applications may not work correctly since aufs inode number for such
+inode will change silently.
+If you do not have any empty files, empty directories or special files,
+inodes on cramfs will be all fine.
+
+A branch should not be shared as the writable branch between multiple
+aufs. A readonly branch can be shared.
+
+The maximum number of branches is configurable at compile time (127 by
+default).
+
+When an unknown permission or attribute is given, aufs sets ro to that
+branch silently.
+
+.SS Permission
+.
+.TP
+.B rw
+Readable and writable branch. Set as default for the first branch.
+If the branch filesystem is mounted as readonly, you cannot set it `rw.'
+.\" A filesystem which does not support link(2) and i_op\->setattr(), for
+.\" example FAT, will not be used as the writable branch.
+.
+.TP
+.B ro
+Readonly branch and it has no whiteouts on it.
+Set as default for all branches except the first one. Aufs never issue
+both of write operation and lookup operation for whiteout to this branch.
+.
+.TP
+.B rr
+Real readonly branch, special case of `ro', for natively readonly
+branch. Assuming the branch is natively readonly, aufs can optimize
+some internal operation. For example, if you specify `udba=inotify'
+option, aufs does not set inotify for the things on rr branch.
+Set by default for a branch whose fs-type is either `iso9660',
+`cramfs' or `romfs' (and `squashfs' for linux\-2.6.29 and later).
+
+When your branch exists on slower device and you have some
+capacity on your hdd, you may want to try ulobdev tool in ULOOP sample.
+It can cache the contents of the real devices on another faster device,
+so you will be able to get the better access performance.
+The ulobdev tool is for a generic block device, and the ulohttp is for a
+filesystem image on http server.
+If you want to spin down your hdd to save the
+battery life or something, then you may want to use ulobdev to save the
+access to the hdd, too.
+See $AufsCVS/sample/uloop in detail.
+
+.SS Attribute
+.

+Readonly branch and it has/might have whiteouts on it.
+Aufs never issue write operation to this branch, but lookup for whiteout.
+Use this as `<branch_dir>=ro+wh'.
+.
+.TP
+.B nolwh
+Usually, aufs creates a whiteout as a hardlink on a writable
+branch. This attributes prohibits aufs to create the hardlinked
+whiteout, including the source file of all hardlinked whiteout
+(\*[AUFS_WH_BASE].)
+If you do not like a hardlink, or your writable branch does not support
+link(2), then use this attribute.
+But I am afraid a filesystem which does not support link(2) natively
+will fail in other place such as copy-up.
+Use this as `<branch_dir>=rw+nolwh'.
+Also you may want to try `noplink' mount option, while it is not recommended.

+.SH External Inode Number Bitmap, Translation Table and Generation Table (xino)
+Aufs uses one external bitmap file and one external inode number
+translation table files per an aufs and per a branch
+filesystem by default.
+Additionally when CONFIG_AUFS_EXPORT is enabled, one external inode
+generation table is added.
+The bitmap (and the generation table) is for recycling aufs inode number
+and the others
+are a table for converting an inode number on a branch to
+an aufs inode number. The default path
+is `first writable branch'/\*[AUFS_XINO_FNAME].
+If there is no writable branch, the
+default path
+will be \*[AUFS_XINO_DEFPATH].
+.\" A user who executes mount(8) needs the privilege to create xino
+.\" file.
+
+If you enable CONFIG_SYSFS, the path of xino files are not shown in
+/proc/mounts (and /etc/mtab), instead it is shown in
+<sysfs>/fs/aufs/si_<id>/xi_path.
+Otherwise, it is shown in /proc/mounts unless it is not the default
+path.
+
+Those files are always opened and read/write by aufs frequently.
+If your writable branch is on flash memory device, it is recommended
+to put xino files on other than flash memory by specifying `xino='
+mount option.
+
+The
+maximum file size of the bitmap is, basically, the amount of the
+number of all the files on all branches divided by 8 (the number of
+bits in a byte).
+For example, on a 4KB page size system, if you have 32,768 (or
+2,599,968) files in aufs world,
+then the maximum file size of the bitmap is 4KB (or 320KB).
+
+The
+maximum file size of the table will
+be `max inode number on the branch x size of an inode number'.
+For example in 32bit environment,
+
+.nf
+$ df -i /branch_fs
+/dev/hda14           2599968  203127 2396841    8% /branch_fs
+.fi
+
+and /branch_fs is an branch of the aufs. When the inode number is
+assigned contiguously (without `hole'), the maximum xino file size for
+/branch_fs will be 2,599,968 x 4 bytes = about 10 MB. But it might not be
+allocated all of disk blocks.
+When the inode number is assigned discontinuously, the maximum size of
+xino file will be the largest inode number on a branch x 4 bytes.
+Additionally, the file size is limited to LLONG_MAX or the s_maxbytes
+in filesystem's superblock (s_maxbytes may be smaller than
+LLONG_MAX). So the
+support-able largest inode number on a branch is less than
+2305843009213693950 (LLONG_MAX/4\-1).
+This is the current limitation of aufs.
+On 64bit environment, this limitation becomes more strict and the
+supported largest inode number is less than LLONG_MAX/8\-1.
+
+The xino files are always hidden, i.e. removed. So you cannot
+do `ls \-l xino_file'.
+If you enable CONFIG_DEBUG_FS, you can check these information through
+<debugfs>/aufs/<si_id>/{xib,xi[0-9]*,xigen}. xib is for the bitmap file,
+xi0 ix for the first branch, and xi1 is for the next. xigen is for the
+generation table.
+xib and xigen are in the format of,
+
+.nf
+<blocks>x<block size> <file size>
+.fi
+
+Note that a filesystem usually has a
+feature called pre-allocation, which means a number of
+blocks are allocated automatically, and then deallocated
+silently when the filesystem thinks they are unnecessary.
+You do not have to be surprised the sudden changes of the number of
+blocks, when your filesystem which xino files are placed supports the
+pre-allocation feature.
+
+The rests are hidden xino file information in the format of,
+
+.nf
+<file count>, <blocks>x<block size> <file size>
+.fi
+
+If the file count is larger than 1, it means some of your branches are
+on the same filesystem and the xino file is shared by them.
+Note that the file size may not be equal to the actual consuming blocks
+since xino file is a sparse file, i.e. a hole in a file which does not
+consume any disk blocks.
+
+Once you unmount aufs, the xino files for that aufs are totally gone.
+It means that the inode number is not permanent across umount or
+shutdown.
+
+The xino files should be created on the filesystem except NFS.
+If your first writable branch is NFS, you will need to specify xino
+file path other than NFS.
+Also if you are going to remove the branch where xino files exist or
+change the branch permission to readonly, you need to use xino option
+before del/mod the branch.
+
+The bitmap file can be truncated.
+For example, if you delete a branch which has huge number of files,
+many inode numbers will be recycled and the bitmap will be truncated
+to smaller size. Aufs does this automatically when a branch is
+deleted.
+You can truncate it anytime you like if you specify `trunc_xib' mount
+option. But when the accessed inode number was not deleted, nothing
+will be truncated.
+If you do not want to truncate it (it may be slow) when you delete a
+branch, specify `notrunc_xib' after `del' mount option.
+
+If you do not want to use xino, use noxino mount option. Use this
+option with care, since the inode number may be changed silently and
+unexpectedly anytime.
+For example,
+rmdir failure, recursive chmod/chown/etc to a large and deep directory
+or anything else.
+And some applications will not work correctly.
+.\" When the inode number has been changed, your system
+.\" can be crazy.
+If you want to change the xino default path, use xino mount option.
+
+After you add branches, the persistence of inode number may not be
+guaranteed.
+At remount time, cached but unused inodes are discarded.
+And the newly appeared inode may have different inode number at the
+next access time. The inodes in use have the persistent inode number.
+
+When aufs assigned an inode number to a file, and if you create the
+same named file on the upper branch directly, then the next time you
+access the file, aufs may assign another inode number to the file even
+if you use xino option.
+Some applications may treat the file whose inode number has been
+changed as totally different file.
+
+.\" ----------------------------------------------------------------------
+.SH Pseudo Link (hardlink over branches)
+Aufs supports `pseudo link' which is a logical hard-link over
+branches (cf. ln(1) and link(2)).
+In other words, a copied-up file by link(2) and a copied-up file which was
+hard-linked on a readonly branch filesystem.
+
+When you have files named fileA and fileB which are
+hardlinked on a readonly branch, if you write something into fileA,
+aufs copies-up fileA to a writable branch, and write(2) the originally
+requested thing to the copied-up fileA. On the writable branch,
+fileA is not hardlinked.
+But aufs remembers it was hardlinked, and handles fileB as if it existed
+on the writable branch, by referencing  fileA's inode on the writable
+branch as fileB's inode.
+
+Once you unmount aufs, the plink info for that aufs kept in memory are totally
+gone.
+It means that the pseudo-link is not permanent.
+If you want to make plink permanent, try `auplink' utility just before
+one of these operations,
+unmounting your aufs,
+using `ro' or `noplink' mount option,
+deleting a branch from aufs,
+adding a branch into aufs,
+or changing your writable branch to readonly.
+
+This utility will reproduces all real hardlinks on a writable branch by linking
+them, and removes pseudo-link info in memory and temporary link on the
+writable branch.
+Since this utility access your branches directly, you cannot hide them by
+`mount \-\-bind /tmp /branch' or something.
+
+If you are willing to rebuild your aufs with the same branches later, you
+should use auplink utility before you umount your aufs.
+If you installed both of /sbin/mount.aufs and /sbin/umount.aufs, and your
+mount(8) and umount(8) support them,
+`auplink' utility will be executed automatically and flush pseudo-links.
+
+.nf
+# auplink /your/aufs/root flush
+# umount /your/aufs/root
+or
+# auplink /your/aufs/root flush
+# mount -o remount,mod:/your/writable/branch=ro /your/aufs/root
+or
+# auplink /your/aufs/root flush
+# mount -o remount,noplink /your/aufs/root
+or
+# auplink /your/aufs/root flush
+# mount -o remount,del:/your/aufs/branch /your/aufs/root
+or
+# auplink /your/aufs/root flush
+# mount -o remount,append:/your/aufs/branch /your/aufs/root
+.fi
+
+The plinks are kept both in memory and on disk. When they consumes too much
+resources on your system, you can use the `auplink' utility at anytime and
+throw away the unnecessary pseudo-links in safe.
+
+Additionally, the `auplink' utility is very useful for some security reasons.
+For example, when you have a directory whose permission flags
+are 0700, and a file who is 0644 under the 0700 directory. Usually,
+all files under the 0700 directory are private and no one else can see
+the file. But when the directory is 0711 and someone else knows the 0644
+filename, he can read the file.
+
+Basically, aufs pseudo-link feature creates a temporary link under the
+directory whose owner is root and the permission flags are 0700.
+But when the writable branch is NFS, aufs sets 0711 to the directory.
+When the 0644 file is pseudo-linked, the temporary link, of course the
+contents of the file is totally equivalent, will be created under the
+0711 directory. The filename will be generated by its inode number.
+While it is hard to know the generated filename, someone else may try peeping
+the temporary pseudo-linked file by his software tool which may try the name
+from one to MAX_INT or something.
+In this case, the 0644 file will be read unexpectedly.
+I am afraid that leaving the temporary pseudo-links can be a security hole.
+It makes sense to execute `auplink /your/aufs/root flush'
+periodically, when your writable branch is NFS.
+
+When your writable branch is not NFS, or all users are careful enough to set 0600
+to their private files, you do not have to worry about this issue.
+
+If you do not want this feature, use `noplink' mount option.
+
+.SS The behaviours of plink and noplink
+This sample shows that the `f_src_linked2' with `noplink' option cannot follow
+the link.

+.SH User's Direct Branch Access (UDBA)
+UDBA means a modification to a branch filesystem manually or directly,
+e.g. bypassing aufs.
+While aufs is designed and implemented to be safe after UDBA,
+it can make yourself and your aufs confused. And some information like
+aufs inode will be incorrect.
+For example, if you rename a file on a branch directly, the file on
+aufs may
+or may not be accessible through both of old and new name.
+Because aufs caches various information about the files on
+branches. And the cache still remains after UDBA.
+
+Aufs has a mount option named `udba' which specifies the test level at
+access time whether UDBA was happened or not.
+.
+.TP
+.B udba=none
+Aufs trusts the dentry and the inode cache on the system, and never
+test about UDBA. With this option, aufs runs fastest, but it may show
+you incorrect data.
+Additionally, if you often modify a branch
+directly, aufs will not be able to trace the changes of inodes on the
+branch. It can be a cause of wrong behaviour, deadlock or anything else.
+
+It is recommended to use this option only when you are sure that
+nobody access a file on a branch.
+It might be difficult for you to achieve real `no UDBA' world when you
+cannot stop your users doing `find / \-ls' or something.
+If you really want to forbid all of your users to UDBA, here is a trick
+for it.
+With this trick, users cannot see the
+branches directly and aufs runs with no problem, except `auplink' utility.
+But if you are not familiar with aufs, this trick may make
+yourself confused.
+

+# d=/tmp/.aufs.hide
+# mkdir $d
+# for i in $branches_you_want_to_hide

+/tmp/.aufs.hide.
+
+.nf
+# umount -n $branches_you_want_to_unbound
+.fi
+
+If you use FUSE filesystem as an aufs branch which supports hardlink,
+you should not set this option, since FUSE makes inode objects for
+each hardlinks (at least in linux\-2.6.23). When your FUSE filesystem
+maintains them at link/unlinking, it is equivalent
+to `direct branch access' for aufs.
+
+.
+.TP
+.B udba=reval
+Aufs tests only the existence of the file which existed. If
+the existed file was removed on the branch directly, aufs
+discard the cache about the file and
+re-lookup it. So the data will be updated.
+This test is at minimum level to keep the performance and ensure the
+existence of a file.
+This is default and aufs runs still fast.
+
+This rule leads to some unexpected situation, but I hope it is
+harmless. Those are totally depends upon cache. Here are just a few
+examples.
+.
+.RS
+.Bu
+If the file is cached as negative or
+not-existed, aufs does not test it. And the file is still handled as
+negative after a user created the file on a branch directly. If the
+file is not cached, aufs will lookup normally and find the file.
+.
+.Bu
+When the file is cached as positive or existed, and a user created the

+file which is on the lower branch.
+.
+.Bu
+When the file is cached as positive or existed, and a user renamed the
+file by rename(2) directly. Aufs detects the inode of the file is
+still existing. You may or may not see both of the old and new files.

+
+If your outer modification (UDBA) is rare and you can ignore the
+temporary and minor differences between virtual aufs world and real
+branch filesystem, then try this mount option.
+.
+.TP
+.B udba=inotify
+Aufs sets `inotify' to all the accessed directories on its branches
+and receives the event about the dir and its children. It consumes
+resources, cpu and memory. And I am afraid that the performance will be
+hurt, but it is most strict test level.
+There are some limitations of linux inotify, see also Inotify
+Limitation.
+So it is recommended to leave udba default option usually, and set it
+to inotify by remount when you need it.
+
+When a user accesses the file which was notified UDBA before, the cached data
+about the file will be discarded and aufs re-lookup it. So the data will
+be updated.
+When an error condition occurs between UDBA and aufs operation, aufs
+will return an error, including EIO.
+To use this option, you need to enable CONFIG_INOTIFY and
+CONFIG_AUFS_UDBA_INOTIFY.
+
+To rename/rmdir a directory on a branch directory may reveal the same named
+directory on the lower branch. Aufs tries re-lookuping the renamed
+directory and the revealed directory and assigning different inode
+number to them. But the inode number including their children can be a
+problem. The inode numbers will be changed silently, and
+aufs may produce a warning. If you rename a directory repeatedly and
+reveal/hide the lower directory, then aufs may confuse their inode
+numbers too. It depends upon the system cache.
+
+When you make a directory in aufs and mount other filesystem on it,
+the directory in aufs cannot be removed expectedly because it is a
+mount point. But the same named directory on the writable branch can
+be removed, if someone wants. It is just an empty directory, instead
+of a mount point.
+Aufs cannot stop such direct rmdir, but produces a warning about it.
+
+If the pseudo-linked file is hardlinked or unlinked on the branch
+directly, its inode link count in aufs may be incorrect. It is
+recommended to flush the pseudo-links by auplink script.
+
+.\" ----------------------------------------------------------------------
+.SH Linux Inotify Limitation
+Unfortunately, current inotify (linux\-2.6.18) has some limitations,
+and aufs must derive it.
+
+.SS IN_ATTRIB, updating atime
+When a file/dir on a branch is accessed directly, the inode atime (access
+time, cf. stat(2)) may or may not be updated. In some cases, inotify
+does not fire this event. So the aufs inode atime may remain old.
+
+.SS IN_ATTRIB, updating nlink
+When the link count of a file on a branch is incremented by link(2)
+directly,
+inotify fires IN_CREATE to the parent
+directory, but IN_ATTRIB to the file. So the aufs inode nlink may
+remain old.
+
+.SS IN_DELETE, removing file on NFS
+When a file on a NFS branch is deleted directly, inotify may or may
+not fire
+IN_DELETE event. It depends upon the status of dentry
+(DCACHE_NFSFS_RENAMED flag).
+In this case, the file on aufs seems still exists. Aufs and any user can see
+the file.
+
+.SS IN_IGNORED, deleted rename target
+When a file/dir on a branch is unlinked by rename(2) directly, inotify
+fires IN_IGNORED which means the inode is deleted. Actually, in some
+cases, the inode survives. For example, the rename target is linked or
+opened. In this case, inotify watch set by aufs is removed by VFS and
+inotify.
+And aufs cannot receive the events anymore. So aufs may show you
+incorrect data about the file/dir.
+
+.\" ----------------------------------------------------------------------
+.SH Virtual or Vertical Directory Block (VDIR)
+In order to provide the merged view of file listing, aufs builds
+internal directory block on memory. For readdir, aufs performs readdir()
+internally for each dir on branches, merges their entries with
+eliminating the whiteout\-ed ones, and sets it to the opened file (dir)
+object. So the file object has its entry list until it is closed. The
+entry list will be updated when the file position is zero (by
+rewinddir(3)) and becomes obsoleted.
+
+Some people may call it can be a security hole or invite DoS attack
+since the opened and once readdir\-ed dir (file object) holds its entry
+list and becomes a pressure for system memory. But I would say it is similar
+to files under /proc or /sys. The virtual files in them also holds a
+memory page (generally) while they are opened. When an idea to reduce
+memory for them is introduced, it will be applied to aufs too.
+
+The dynamically allocated memory block for the name of entries has a
+unit of \*[AUFS_RDBLK_DEF] bytes by default.
+During building dir blocks, aufs creates hash list (hashed and divided by
+\*[AUFS_RDHASH_DEF] by default) and judging whether
+the entry is whiteouted by its upper branch or already listed.
+
+These values are suitable for normal environments. But you may have
+millions of files or very long filenames under a single directory. For
+such cases, you may need to customize these values by specifying rdblk=
+and rdhash= aufs mount options.
+
+For instance, there are 97 files under my /bin, and the total name
+length is 597 bytes.
+
+.nf
+$ \\ls -1 /bin | wc
+     97      97     597
+.fi
+
+Strictly speaking, 97 end\-of\-line codes are
+included. But it is OK since aufs VDIR also stores the name length in 1
+byte. In this case, you do not need to customize the default values. 597 bytes
+filenames will be stored in 2 VDIR memory blocks (597 <
+\*[AUFS_RDBLK_DEF] x 2).
+And 97 filenames are distributed among \*[AUFS_RDHASH_DEF] lists, so one
+list will point 4 names in average. To judge the names is whiteouted or
+not, the number of comparison will be 4. 2 memory allocations
+and 4 comparison costs low (even if the directory is opened for a long
+time). So you do not need to customize.
+
+If your directory has millions of files, the you will need to specify
+rdblk= and rdhash=.
+
+.nf
+$ ls -U /mnt/rotating-rust | wc -l
+1382438
+.fi
+
+In this case, assuming the average length of filenames is 6, in order to
+get better time performance I would
+recommend to set $((128*1024)) or $((64*1024)) for rdblk, and
+$((8*1024)) or $((4*1024)) for rdhash.
+You can change these values of the active aufs mount by "mount -o
+remount".
+
+This customization is not for
+reducing the memory space, but for reducing time for the number of memory
+allocation and the name comparison. The larger value is faster, in
+general. Of course, you will need system memory. This is a generic
+"time\-vs\-space" problem.
+
+.\" ----------------------------------------------------------------------
+.SH Copy On Write, or aufs internal copyup and copydown
+Every stackable filesystem which implements copy\-on\-write supports the
+copyup feature. The feature is to copy a file/dir from the lower branch
+to the upper internally. When you have one readonly branch and one
+upper writable branch, and you append a string to a file which exists on
+the readonly branch, then aufs will copy the file from the readonly
+branch to the writable branch with its directory hierarchy. It means one
+write(2) involves several logical/internal mkdir(2), creat(2), read(2),
+write(2) and close(2) systemcalls
+before the actual expected write(2) is performed. Sometimes it may take
+a long time, particularly when the file is very large.
+If CONFIG_AUFS_DEBUG is enabled, aufs produces a message saying `copying
+a large file.'
+
+You may see the message when you change the xino file path or
+truncate the xino/xib files. Sometimes those files can be large and may
+take a long time to handle them.
+
+.\" ----------------------------------------------------------------------
+.SH Policies to Select One among Multiple Writable Branches
+Aufs has some policies to select one among multiple writable branches
+when you are going to write/modify something. There are two kinds of
+policies, one is for newly create something and the other is for
+internal copy-up.
+You can select them by specifying mount option `create=CREATE_POLICY'
+or `cpup=COPYUP_POLICY.'
+These policies have no meaning when you have only one writable
+branch. If there is some meaning, it must hurt the performance.
+
+.SS Exceptions for Policies
+In every cases below, even if the policy says that the branch where a
+new file should be created is /rw2, the file will be created on /rw1.
+.
+.Bu
+If there is a readonly branch with `wh' attribute above the
+policy-selected branch and the parent dir is marked as opaque,
+or the target (creating) file is whiteouted on the ro+wh branch, then
+the policy will be ignored and the target file will be created on the
+nearest upper writable branch than the ro+wh branch.
+.RS
+.nf
+/aufs = /rw1 + /ro+wh/diropq + /rw2
+/aufs = /rw1 + /ro+wh/wh.tgt + /rw2
+.fi
+.RE
+.
+.Bu
+If there is a writable branch above the policy-selected branch and the
+parent dir is marked as opaque or the target file is whiteouted on the
+branch, then the policy will be ignored and the target file will be
+created on the highest one among the upper writable branches who has
+diropq or whiteout. In case of whiteout, aufs removes it as usual.
+.RS
+.nf
+/aufs = /rw1/diropq + /rw2
+/aufs = /rw1/wh.tgt + /rw2
+.fi
+.RE
+.
+.Bu
+link(2) and rename(2) systemcalls are exceptions in every policy.
+They try selecting the branch where the source exists as possible since
+copyup a large file will take long time. If it can't be, ie. the
+branch where the source exists is readonly, then they will follow the
+copyup policy.
+.
+.Bu
+There is an exception for rename(2) when the target exists.
+If the rename target exists, aufs compares the index of the branches
+where the source and the target are existing and selects the higher
+one. If the selected branch is readonly, then aufs follows the copyup
+policy.
+
+.SS Policies for Creating
+.
+.TP
+.B create=tdp | top\-down\-parent
+Selects the highest writable branch where the parent dir exists. If
+the parent dir does not exist on a writable branch, then the internal
+copyup will happen. The policy for this copyup is always `bottom-up.'
+This is the default policy.
+.
+.TP
+.B create=rr | round\-robin
+Selects a writable branch in round robin. When you have two writable
+branches and creates 10 new files, 5 files will be created for each
+branch.
+mkdir(2) systemcall is an exception. When you create 10 new directories,
+all are created on the same branch.
+.
+.TP
+.B create=mfs[:second] | most\-free\-space[:second]
+Selects a writable branch which has most free space. In order to keep
+the performance, you can specify the duration (`second') which makes
+aufs hold the index of last selected writable branch until the
+specified seconds expires. The first time you create something in aufs
+after the specified seconds expired, aufs checks the amount of free
+space of all writable branches by internal statfs call
+and the held branch index will be updated.
+The default value is \*[AUFS_MFS_SECOND_DEF] seconds.
+.
+.TP
+.B create=mfsrr:low[:second]
+Selects a writable branch in most-free-space mode first, and then
+round-robin mode. If the selected branch has less free space than the
+specified value `low' in bytes, then aufs re-tries in round-robin mode.
+.\" `G', `M' and `K' (case insensitive) can be followed after `low.' Or
+Try an arithmetic expansion of shell which is defined by POSIX.
+For example, $((10 * 1024 * 1024)) for 10M.
+You can also specify the duration (`second') which is equivalent to
+the `mfs' mode.
+.
+.TP
+.B create=pmfs[:second]
+Selects a writable branch where the parent dir exists, such as tdp
+mode. When the parent dir exists on multiple writable branches, aufs
+selects the one which has most free space, such as mfs mode.
+
+.SS Policies for Copy-Up
+.
+.TP
+.B cpup=tdp | top\-down\-parent
+Equivalent to the same named policy for create.
+This is the default policy.
+.
+.TP
+.B cpup=bup | bottom\-up\-parent
+Selects the writable branch where the parent dir exists and the branch
+is nearest upper one from the copyup-source.
+.
+.TP
+.B cpup=bu | bottom\-up
+Selects the nearest upper writable branch from the copyup-source,
+regardless the existence of the parent dir.
+
+.\" ----------------------------------------------------------------------
+.SH Exporting Aufs via NFS
+Aufs is supporting NFS-exporting.
+Since aufs has no actual block device, you need to add NFS `fsid' option at
+exporting. Refer to the manual of NFS about the detail of this option.
+
+There are some limitations or requirements.
+.RS
+.Bu
+The branch filesystem must support NFS-exporting.
+.Bu
+NFSv2 is not supported. When you mount the exported aufs from your NFS
+client, you will need to some NFS options like v3 or nfsvers=3,
+especially if it is nfsroot.
+.Bu
+If the size of the NFS file handle on your branch filesystem is large,
+aufs will
+not be able to handle it. The maximum size of NFSv3 file
+handle for a filesystem is 64 bytes. Aufs uses 24 bytes for 32bit
+system, plus 12 bytes for 64bit system. The rest is a room for a file
+handle of a branch filesystem.
+.Bu
+The External Inode Number Bitmap, Translation Table and Generation Table
+(xino) is
+required since NFS file
+handle is based upon inode number. The mount option `xino' is enabled
+by default.
+The external inode generation table and its debugfs entry
+(<debugfs>/aufs/si_*/xigen) is created when CONFIG_AUFS_EXPORT is
+enabled even if you don't export aufs actually.
+The size of the external inode generation table grows only, never be
+truncated. You might need to pay attention to the free space of the
+filesystem where xino files are placed. By default, it is the first
+writable branch.
+.Bu
+The branch filesystems must be accessible, which means `not hidden.'
+It means you need to `mount \-\-move' when you use initramfs and
+switch_root(8), or chroot(8).
+.RE
+
+.\" ----------------------------------------------------------------------
+.SH Dentry and Inode Caches
+If you want to clear caches on your system, there are several tricks
+for that. If your system ram is low,
+try `find /large/dir \-ls > /dev/null'.
+It will read many inodes and dentries and cache them. Then old caches will be
+discarded.
+But when you have large ram or you do not have such large
+directory, it is not effective.
+
+If you want to discard cache within a certain filesystem,
+try `mount \-o remount /your/mntpnt'. Some filesystem may return an error of
+EINVAL or something, but VFS discards the unused dentry/inode caches on the
+specified filesystem.
+
+.\" ----------------------------------------------------------------------
+.SH Compatible/Incompatible with Unionfs Version 1.x Series
+If you compile aufs with \-DCONFIG_AUFS_COMPAT, dirs= option and =nfsro
+branch permission flag are available. They are interpreted as
+br: option and =ro flags respectively.
+ `debug', `delete', `imap' options are ignored silently. When you
+compile aufs without \-DCONFIG_AUFS_COMPAT, these three options are
+also ignored, but a warning message is issued.
+
+Ignoring `delete' option, and to keep filesystem consistency, aufs tries
+writing something to only one branch in a single systemcall. It means
+aufs may copyup even if the copyup-src branch is specified as writable.
+For example, you have two writable branches and a large regular file
+on the lower writable branch. When you issue rename(2) to the file on aufs,
+aufs may copyup it to the upper writable branch.
+If this behaviour is not what you want, then you should rename(2) it
+on the lower branch directly.
+
+And there is a simple shell
+script `unionctl' under sample subdirectory, which is compatible with
+unionctl(8) in
+Unionfs Version 1.x series, except \-\-query action.
+This script executes mount(8) with `remount' option and uses
+add/del/mod aufs mount options.
+If you are familiar with Unionfs Version 1.x series and want to use unionctl(8), you can
+try this script instead of using mount \-o remount,... directly.
+Aufs does not support ioctl(2) interface.
+This script is highly depending upon mount(8) in
+util\-linux\-2.12p package, and you need to mount /proc to use this script.
+If your mount(8) version differs, you can try modifying this
+script. It is very easy.
+The unionctl script is just for a sample usage of aufs remount
+interface.
+
+Aufs uses the external inode number bitmap and translation table by
+default.
+
+The default branch permission for the first branch is `rw', and the
+rest is `ro.'
+
+The whiteout is for hiding files on lower branches. Also it is applied
+to stop readdir going lower branches.
+The latter case is called `opaque directory.' Any
+whiteout is an empty file, it means whiteout is just an mark.
+In the case of hiding lower files, the name of whiteout is
+`\*[AUFS_WH_PFX]<filename>.'
+And in the case of stopping readdir, the name is
+`\*[AUFS_WH_PFX]\*[AUFS_WH_PFX].opq' or
+`\*[AUFS_WH_PFX]__dir_opaque.' The name depends upon your compile
+configuration
+CONFIG_AUFS_COMPAT.
+.\" All of newly created or renamed directory will be opaque.
+All whiteouts are hardlinked,
+including `<writable branch top dir>/\*[AUFS_WH_BASE].'
+
+The hardlink on an ordinary (disk based) filesystem does not
+consume inode resource newly. But in linux tmpfs, the number of free
+inodes will be decremented by link(2). It is recommended to specify
+nr_inodes option to your tmpfs if you meet ENOSPC. Use this option
+after checking by `df \-i.'
+
+When you rmdir or rename-to the dir who has a number of whiteouts,
+aufs rename the dir to the temporary whiteouted-name like
+`\*[AUFS_WH_PFX]<dir>.<random hex>.' Then remove it after actual operation.
+cf. mount option `dirwh.'
+
+.\" ----------------------------------------------------------------------
+.SH Incompatible with an Ordinary Filesystem
+stat(2) returns the inode info from the first existence inode among
+the branches, except the directory link count.
+Aufs computes the directory link count larger than the exact value usually, in
+order to keep UNIX filesystem semantics, or in order to shut find(1) mouth up.
+The size of a directory may be wrong too, but it has to do no harm.
+The timestamp of a directory will not be updated when a file is
+created or removed under it, and it was done on a lower branch.
+
+The test for permission bits has two cases. One is for a directory,
+and the other is for a non-directory. In the case of a directory, aufs
+checks the permission bits of all existing directories. It means you
+need the correct privilege for the directories including the lower
+branches.
+The test for a non-directory is more simple. It checks only the
+topmost inode.
+
+statfs(2) returns the information of the first branch info except
+namelen when `nosum' is specified (the default). The namelen is
+decreased by the whiteout prefix length. And the block size may differ
+from st_blksize which is obtained by stat(2).
+
+Remember, seekdir(3) and telldir(3) are not defined in POSIX. They may
+not work as you expect. Try rewinddir(3) or re-open the dir.
+
+The whiteout prefix (\*[AUFS_WH_PFX]) is reserved on all branches. Users should
+not handle the filename begins with this prefix.
+In order to future whiteout, the maximum filename length is limited by
+the longest value \- \*[AUFS_WH_PFX_LEN]. It may be a violation of POSIX.
+
+If you dislike the difference between the aufs entries in /etc/mtab
+and /proc/mounts, and if you are using mount(8) in util\-linux package,
+then try ./mount.aufs utility. Copy the script to /sbin/mount.aufs.
+This simple utility tries updating
+/etc/mtab. If you do not care about /etc/mtab, you can ignore this
+utility.
+Remember this utility is highly depending upon mount(8) in
+util\-linux\-2.12p package, and you need to mount /proc.
+
+Since aufs uses its own inode and dentry, your system may cache huge
+number of inodes and dentries. It can be as twice as all of the files
+in your union.
+It means that unmounting or remounting readonly at shutdown time may
+take a long time, since mount(2) in VFS tries freeing all of the cache
+on the target filesystem.
+
+When you open a directory, aufs will open several directories
+internally.
+It means you may reach the limit of the number of file descriptor.
+And when the lower directory cannot be opened, aufs will close all the
+opened upper directories and return an error.
+
+The sub-mount under the branch
+of local filesystem
+is ignored.
+For example, if you have mount another filesystem on
+/branch/another/mntpnt, the files under `mntpnt' will be ignored by aufs.
+It is recommended to mount the sub-mount under the mounted aufs.
+For example,
+
+.nf
+# sudo mount /dev/sdaXX /ro_branch
+# d=another/mntpnt
+# sudo mount /dev/sdbXX /ro_branch/$d
+# mkdir -p /rw_branch/$d
+# sudo mount -t aufs -o br:/rw_branch:/ro_branch none /aufs
+# sudo mount -t aufs -o br:/rw_branch/${d}:/ro_branch/${d} none /aufs/another/$d
+.fi
+
+There are several characters which are not allowed to use in a branch
+directory path and xino filename. See detail in Branch Syntax and Mount
+Option.
+
+The file-lock which means fcntl(2) with F_SETLK, F_SETLKW or F_GETLK, flock(2)
+and lockf(3), is applied to virtual aufs file only, not to the file on a
+branch. It means you can break the lock by accessing a branch directly.
+TODO: check `security' to hook locks, as inotify does.
+
+The I/O to the named pipe or local socket are not handled by aufs, even
+if it exists in aufs. After the reader and the writer established their
+connection if the pipe/socket are copied-up, they keep using the old one
+instead of the copied-up one.
+
+The fsync(2) and fdatasync(2) systemcalls return 0 which means success, even
+if the given file descriptor is not opened for writing.
+I am afraid this behaviour may violate some standards. Checking the
+behaviour of fsync(2) on ext2, aufs decided to return success.
+
+If you want to use disk-quota, you should set it up to your writable
+branch since aufs does not have its own block device.
+
+When your aufs is the root directory of your system, and your system
+tells you some of the filesystem were not unmounted cleanly, try these
+procedure when you shutdown your system.
+.nf
+# mount -no remount,ro /
+# for i in $writable_branches
+# do mount -no remount,ro $i
+# done
+.fi
+If your xino file is on a hard drive, you also need to specify
+`noxino' option or `xino=/your/tmpfs/xino' at remounting root
+directory.
+
+To rename(2) directory may return EXDEV even if both of src and tgt
+are on the same aufs. When the rename-src dir exists on multiple
+branches and the lower dir has child(ren), aufs has to copyup all his
+children. It can be recursive copyup. Current aufs does not support
+such huge copyup operation at one time in kernel space, instead
+produces a warning and returns EXDEV.
+Generally, mv(1) detects this error and tries mkdir(2) and
+rename(2) or copy/unlink recursively. So the result is harmless.
+If your application which issues rename(2) for a directory does not
+support EXDEV, it will not work on aufs.
+Also this specification is applied to the case when the src directory
+exists on the lower readonly branch and it has child(ren).
+
+If a sudden accident such like a power failure happens during aufs is
+performing, and regular fsck for branch filesystems is completed after
+the disaster, you need to extra fsck for aufs writable branches. It is
+necessary to check whether the whiteout remains incorrectly or not,
+eg. the real filename and the whiteout for it under the same parent
+directory. If such whiteout remains, aufs cannot handle the file
+correctly.
+To check the consistency from the aufs' point of view, you can use a
+simple shell script called /sbin/auchk. Its purpose is a fsck tool for
+aufs, and it checks the illegal whiteout, the remained
+pseudo-links and the remained aufs-temp files. If they are found, the
+utility reports you and asks whether to delete or not.
+It is recommended to execute /sbin/auchk for every writable branch
+filesystem before mounting aufs if the system experienced crash.
+
+
+.\" ----------------------------------------------------------------------
+.SH EXAMPLES
+The mount options are interpreted from left to right at remount-time.
+These examples
+shows how the options are handled. (assuming /sbin/mount.aufs was
+installed)

+
+When you use aufs as root filesystem, it is recommended to consider to
+exclude some directories. For example, /tmp and /var/log are not need
+to stack in many cases. They do not usually need to copyup or to whiteout.
+Also the swapfile on aufs (a regular file, not a block device) is not
+supported.
+In order to exclude the specific dir from aufs, try bind mounting.
+
+And there is a good sample which is for network booted diskless machines. See
+sample/ in detail.
+
+.\" ----------------------------------------------------------------------
+.SH DIAGNOSTICS
+When you add a branch to your union, aufs may warn you about the
+privilege or security of the branch, which is the permission bits,
+owner and group of the top directory of the branch.
+For example, when your upper writable branch has a world writable top
+directory,
+a malicious user can create any files on the writable branch directly,
+like copyup and modify manually. I am afraid it can be a security
+issue.
+
+When you mount or remount your union without \-o ro common mount option
+and without writable branch, aufs will warn you that the first branch
+should be writable.
+
+.\" It is discouraged to set both of `udba' and `noxino' mount options. In
+.\" this case the inode number under aufs will always be changed and may
+.\" reach the end of inode number which is a maximum of unsigned long. If
+.\" the inode number reaches the end, aufs will return EIO repeatedly.
+
+When you set udba other than inotify and change something on your
+branch filesystem directly, later aufs may detect some mismatches to
+its cache. If it is a critical mismatch, aufs returns EIO.
+
+When an error occurs in aufs, aufs prints the kernel message with
+`errno.' The priority of the message (log level) is ERR or WARNING which
+depends upon the message itself.
+You can convert the `errno' into the error message by perror(3),
+strerror(3) or something.
+For example, the `errno' in the message `I/O Error, write failed (\-28)'
+is 28 which means ENOSPC or `No space left on device.'
+
+When CONFIG_AUFS_BR_RAMFS is enabled, you can specify ramfs as an aufs
+branch. Since ramfs is simple, it does not set the maximum link count
+originally. In aufs, it is very dangerous, particularly for
+whiteouts. Finally aufs sets the maximum link count for ramfs. The
+value is 32000 which is borrowed from ext2.

++# These exist entirely to fool aclocal when bootstrapping libtool.
++#
++# In the past libtool.m4 has provided macros via AC_DEFUN (or AU_DEFUN)
++# which have later been changed to m4_define as they aren't part of the
++# exported API, or moved to Autoconf or Automake where they belong.
++#
++# The trouble is, aclocal is a bit thick.  It'll see the old AC_DEFUN
++# in /usr/share/aclocal/libtool.m4 and remember it, then when it sees us
++# using a macro with the same name in our local m4/libtool.m4 it'll
++# pull the old libtool.m4 in (it doesn't see our shiny new m4_define
++# and doesn't know about Autoconf macros at all.)
++#
++# So we provide this file, which has a silly filename so it's always
++# included after everything else.  This provides aclocal with the
++# AC_DEFUNs it wants, but when m4 processes it, it doesn't do anything
++# because those macros already exist, or will be overwritten later.
++# We use AC_DEFUN over AU_DEFUN for compatibility with aclocal-1.6. 
++#
++# Anytime we withdraw an AC_DEFUN or AU_DEFUN, remember to add it here.
++# Yes, that means every name once taken will need to remain here until
++# we give up compatibility with versions before 1.7, at which point
++# we need to keep only those names which we still refer to.

-+ *  -----
-+ *  Flags is the bitwise "or" values for command configuration.  A single
-+ *  encrypt direction needs to be set:
-+ *
-+ *	HIFN_ENCODE or HIFN_DECODE
-+ *
-+ *  To use cryptography, a single crypto algorithm must be included:
-+ *
-+ *	HIFN_CRYPT_3DES or HIFN_CRYPT_DES
-+ *
-+ *  To use authentication is used, a single MAC algorithm must be included:
-+ *
-+ *	HIFN_MAC_MD5 or HIFN_MAC_SHA1
-+ *
-+ *  By default MD5 uses a 16 byte hash and SHA-1 uses a 20 byte hash.
-+ *  If the value below is set, hash values are truncated or assumed
-+ *  truncated to 12 bytes:
-+ *
-+ *	HIFN_MAC_TRUNC
-+ *
-+ *  Keys for encryption and authentication can be sent as part of a command,
-+ *  or the last key value used with a particular session can be retrieved
-+ *  and used again if either of these flags are not specified.
-+ *
-+ *	HIFN_CRYPT_NEW_KEY, HIFN_MAC_NEW_KEY
-+ *
-+ *  session_num
-+ *  -----------
-+ *  A number between 0 and 2048 (for DRAM models) or a number between 
-+ *  0 and 768 (for SRAM models).  Those who don't want to use session
-+ *  numbers should leave value at zero and send a new crypt key and/or
-+ *  new MAC key on every command.  If you use session numbers and
-+ *  don't send a key with a command, the last key sent for that same
-+ *  session number will be used.
-+ *
-+ *  Warning:  Using session numbers and multiboard at the same time
-+ *            is currently broken.

-+ *  ---------------
-+ *  The number of bytes of the source_buf that are skipped over before

-+ *  *** Value ignored if authentication not used ***
-+ *
-+ *  crypt_header_skip
-+ *  -----------------
-+ *  The number of bytes of the source_buf that are skipped over before
-+ *  the cryptographic operation begins.  This must be a number between 0
-+ *  and 2^16-1.  For IPsec, this number will always be 8 bytes larger

-+ *
-+ *  Blocking/Non-blocking Issues
-+ *  ============================
-+ *  The driver cannot block in hifn_crypto (no calls to tsleep) currently.
-+ *  hifn_crypto() returns HIFN_CRYPTO_RINGS_FULL if there is not enough
-+ *  room in any of the rings for the request to proceed.
-+ *
-+ *  Return Values
-+ *  =============
-+ *  0 for success, negative values on error
-+ *
-+ *  Defines for negative error codes are:
-+ *  
-+ *    HIFN_CRYPTO_BAD_INPUT  :  The passed in command had invalid settings.
-+ *    HIFN_CRYPTO_RINGS_FULL :  All DMA rings were full and non-blocking
-+ *                              behaviour was requested.

-+README - ocf-linux-20071215
-+---------------------------
-+
-+This README provides instructions for getting ocf-linux compiled and
-+operating in a generic linux environment.  For other information you
-+might like to visit the home page for this project:
-+
-+    http://ocf-linux.sourceforge.net/
-+
-+Adding OCF to linux
-+-------------------
-+
-+    Not much in this file for now,  just some notes.  I usually build
-+    the ocf support as modules but it can be built into the kernel as
-+    well.  To use it:
-+
-+    * mknod /dev/crypto c 10 70
-+
-+    * to add OCF to your kernel source,  you have two options.  Apply
-+      the kernel specific patch:
-+
-+          cd linux-2.4*; gunzip < ocf-linux-24-XXXXXXXX.patch.gz | patch -p1
-+          cd linux-2.6*; gunzip < ocf-linux-26-XXXXXXXX.patch.gz | patch -p1
-+    
-+      if you do one of the above,  then you can proceed to the next step,
-+      or you can do the above process by hand with using the patches against
-+      linux-2.4.35 and 2.6.23 to include the ocf code under crypto/ocf.
-+      Here's how to add it:
-+
-+      for 2.4.35 (and later)
-+
-+          cd linux-2.4.35/crypto
-+          tar xvzf ocf-linux.tar.gz
-+          cd ..
-+          patch -p1 < crypto/ocf/patches/linux-2.4.35-ocf.patch
-+
-+      for 2.6.23 (and later),  find the kernel patch specific (or nearest)
-+      to your kernel versions and then:
-+
-+          cd linux-2.6.NN/crypto
-+          tar xvzf ocf-linux.tar.gz
-+          cd ..
-+          patch -p1 < crypto/ocf/patches/linux-2.6.NN-ocf.patch
-+
-+      It should be easy to take this patch and apply it to other more
-+      recent versions of the kernels.  The same patches should also work
-+      relatively easily on kernels as old as 2.6.11 and 2.4.18.
-+      
-+    * under 2.4 if you are on a non-x86 platform,  you may need to:
-+
-+        cp linux-2.X.x/include/asm-i386/kmap_types.h linux-2.X.x/include/asm-YYY
-+
-+      so that you can build the kernel crypto support needed for the cryptosoft
-+      driver.
-+
-+    * For simplicity you should enable all the crypto support in your kernel
-+      except for the test driver.  Likewise for the OCF options.  Do not
-+      enable OCF crypto drivers for HW that you do not have (for example
-+      ixp4xx will not compile on non-Xscale systems).
-+
-+    * make sure that cryptodev.h (from ocf-linux.tar.gz) is installed as
-+      crypto/cryptodev.h in an include directory that is used for building
-+      applications for your platform.  For example on a host system that
-+      might be:
-+
-+              /usr/include/crypto/cryptodev.h
-+
-+    * patch your openssl-0.9.8i code with the openssl-0.9.8i.patch.
-+      (NOTE: there is no longer a need to patch ssh). The patch is against:
-+      openssl-0_9_8e
-+
-+      If you need a patch for an older version of openssl,  you should look
-+      to older OCF releases.  This patch is unlikely to work on older
-+      openssl versions.
-+
-+      openssl-0.9.8i.patch
-+                - enables --with-cryptodev for non BSD systems
-+                - adds -cpu option to openssl speed for calculating CPU load
-+                  under linux
-+                - fixes null pointer in openssl speed multi thread output.
-+                - fixes test keys to work with linux crypto's more stringent
-+                  key checking.
-+                - adds MD5/SHA acceleration (Ronen Shitrit), only enabled
-+                  with the --with-cryptodev-digests option
-+                - fixes bug in engine code caching.
-+
-+    * build crypto-tools-XXXXXXXX.tar.gz if you want to try some of the BSD
-+      tools for testing OCF (ie., cryptotest).
-+
-+How to load the OCF drivers
-+---------------------------
-+
-+    First insert the base modules:
-+
-+        insmod ocf
-+        insmod cryptodev
-+
-+    You can then install the software OCF driver with:
-+
-+        insmod cryptosoft
-+
-+    and one or more of the OCF HW drivers with:
-+
-+        insmod safe
-+        insmod hifn7751
-+        insmod ixp4xx
-+        ...
-+
-+    all the drivers take a debug option to enable verbose debug so that
-+    you can see what is going on.  For debug you load them as:
-+
-+        insmod ocf crypto_debug=1
-+        insmod cryptodev cryptodev_debug=1
-+        insmod cryptosoft swcr_debug=1
-+
-+    You may load more than one OCF crypto driver but then there is no guarantee
-+    as to which will be used.
-+
-+    You can also enable debug at run time on 2.6 systems with the following:
-+
-+        echo 1 > /sys/module/ocf/parameters/crypto_debug
-+        echo 1 > /sys/module/cryptodev/parameters/cryptodev_debug
-+        echo 1 > /sys/module/cryptosoft/parameters/swcr_debug
-+        echo 1 > /sys/module/hifn7751/parameters/hifn_debug
-+        echo 1 > /sys/module/safe/parameters/safe_debug
-+        echo 1 > /sys/module/ixp4xx/parameters/ixp_debug
-+        ...
-+
-+Testing the OCF support
-+-----------------------
-+
-+    run "cryptotest",  it should do a short test for a couple of
-+    des packets.  If it does everything is working.
-+
-+    If this works,  then ssh will use the driver when invoked as:
-+
-+        ssh -c 3des username@host
-+
-+    to see for sure that it is operating, enable debug as defined above.
-+
-+    To get a better idea of performance run:
-+
-+        cryptotest 100 4096
-+
-+    There are more options to cryptotest,  see the help.
-+
-+    It is also possible to use openssl to test the speed of the crypto
-+    drivers.
-+
-+        openssl speed -evp des -engine cryptodev -elapsed
-+        openssl speed -evp des3 -engine cryptodev -elapsed
-+        openssl speed -evp aes128 -engine cryptodev -elapsed
-+
-+    and multiple threads (10) with:
-+
-+        openssl speed -evp des -engine cryptodev -elapsed -multi 10
-+        openssl speed -evp des3 -engine cryptodev -elapsed -multi 10
-+        openssl speed -evp aes128 -engine cryptodev -elapsed -multi 10
-+
-+    for public key testing you can try:
-+
-+        cryptokeytest
-+        openssl speed -engine cryptodev rsa -elapsed
-+        openssl speed -engine cryptodev dsa -elapsed

-+ * ---------------------------------------------------------------------------
-+ *
-+ * NOTES:
-+ *
-+ * The Freescale SEC (also known as 'talitos') resides on the
-+ * internal bus, and runs asynchronous to the processor core.  It has
-+ * a wide gamut of cryptographic acceleration features, including single-
-+ * pass IPsec (also known as algorithm chaining).  To properly utilize 
-+ * all of the SEC's performance enhancing features, further reworking 
-+ * of higher level code (framework, applications) will be necessary.
-+ *
-+ * The following table shows which SEC version is present in which devices:
-+ * 
-+ * Devices       SEC version
-+ *
-+ * 8272, 8248    SEC 1.0
-+ * 885, 875      SEC 1.2
-+ * 8555E, 8541E  SEC 2.0
-+ * 8349E         SEC 2.01
-+ * 8548E         SEC 2.1
-+ *
-+ * The following table shows the features offered by each SEC version:
-+ *
-+ * 	                       Max.   chan-
-+ * version  Bus I/F       Clock  nels  DEU AESU AFEU MDEU PKEU RNG KEU

-+ * SEC 1.0  internal 64b  100MHz   4     1    1    1    1    1   1   0
-+ * SEC 1.2  internal 32b   66MHz   1     1    1    0    1    0   0   0
-+ * SEC 2.0  internal 64b  166MHz   4     1    1    1    1    1   1   0
-+ * SEC 2.01 internal 64b  166MHz   4     1    1    1    1    1   1   0
-+ * SEC 2.1  internal 64b  333MHz   4     1    1    1    1    1   1   1
-+ *
-+ * Each execution unit in the SEC has two modes of execution; channel and
-+ * slave/debug.  This driver employs the channel infrastructure in the
-+ * device for convenience.  Only the RNG is directly accessed due to the
-+ * convenience of its random fifo pool.  The relationship between the
-+ * channels and execution units is depicted in the following diagram:
-+ *
-+ *    -------   ------------
-+ * ---| ch0 |---|          |
-+ *    -------   |          |
-+ *              |          |------+-------+-------+-------+------------
-+ *    -------   |          |      |       |       |       |           |
-+ * ---| ch1 |---|          |      |       |       |       |           |

-+ *    -------   |          |
-+ * ---| ch3 |---|          |
-+ *    -------   ------------
-+ *
-+ * Channel ch0 may drive an aes operation to the aes unit (AESU),
-+ * and, at the same time, ch1 may drive a message digest operation
-+ * to the mdeu. Each channel has an input descriptor FIFO, and the 
-+ * FIFO can contain, e.g. on the 8541E, up to 24 entries, before a
-+ * a buffer overrun error is triggered. The controller is responsible
-+ * for fetching the data from descriptor pointers, and passing the 
-+ * data to the appropriate EUs. The controller also writes the 
-+ * cryptographic operation's result to memory. The SEC notifies 
-+ * completion by triggering an interrupt and/or setting the 1st byte 
-+ * of the hdr field to 0xff.
-+ *
-+ * TODO:
-+ * o support more algorithms
-+ * o support more versions of the SEC
-+ * o add support for linux 2.4
-+ * o scatter-gather (sg) support
-+ * o add support for public key ops (PKEU)
-+ * o add statistics

-+README - ocf-linux-20071215
-+---------------------------
-+
-+This README provides instructions for getting ocf-linux compiled and
-+operating in a generic linux environment.  For other information you
-+might like to visit the home page for this project:
-+
-+    http://ocf-linux.sourceforge.net/
-+
-+Adding OCF to linux
-+-------------------
-+
-+    Not much in this file for now,  just some notes.  I usually build
-+    the ocf support as modules but it can be built into the kernel as
-+    well.  To use it:
-+
-+    * mknod /dev/crypto c 10 70
-+
-+    * to add OCF to your kernel source,  you have two options.  Apply
-+      the kernel specific patch:
-+
-+          cd linux-2.4*; gunzip < ocf-linux-24-XXXXXXXX.patch.gz | patch -p1
-+          cd linux-2.6*; gunzip < ocf-linux-26-XXXXXXXX.patch.gz | patch -p1
-+    
-+      if you do one of the above,  then you can proceed to the next step,
-+      or you can do the above process by hand with using the patches against
-+      linux-2.4.35 and 2.6.23 to include the ocf code under crypto/ocf.
-+      Here's how to add it:
-+
-+      for 2.4.35 (and later)
-+
-+          cd linux-2.4.35/crypto
-+          tar xvzf ocf-linux.tar.gz
-+          cd ..
-+          patch -p1 < crypto/ocf/patches/linux-2.4.35-ocf.patch
-+
-+      for 2.6.23 (and later),  find the kernel patch specific (or nearest)
-+      to your kernel versions and then:
-+
-+          cd linux-2.6.NN/crypto
-+          tar xvzf ocf-linux.tar.gz
-+          cd ..
-+          patch -p1 < crypto/ocf/patches/linux-2.6.NN-ocf.patch
-+
-+      It should be easy to take this patch and apply it to other more
-+      recent versions of the kernels.  The same patches should also work
-+      relatively easily on kernels as old as 2.6.11 and 2.4.18.
-+      
-+    * under 2.4 if you are on a non-x86 platform,  you may need to:
-+
-+        cp linux-2.X.x/include/asm-i386/kmap_types.h linux-2.X.x/include/asm-YYY
-+
-+      so that you can build the kernel crypto support needed for the cryptosoft
-+      driver.
-+
-+    * For simplicity you should enable all the crypto support in your kernel
-+      except for the test driver.  Likewise for the OCF options.  Do not
-+      enable OCF crypto drivers for HW that you do not have (for example
-+      ixp4xx will not compile on non-Xscale systems).
-+
-+    * make sure that cryptodev.h (from ocf-linux.tar.gz) is installed as
-+      crypto/cryptodev.h in an include directory that is used for building
-+      applications for your platform.  For example on a host system that
-+      might be:
-+
-+              /usr/include/crypto/cryptodev.h
-+
-+    * patch your openssl-0.9.8i code with the openssl-0.9.8i.patch.
-+      (NOTE: there is no longer a need to patch ssh). The patch is against:
-+      openssl-0_9_8e
-+
-+      If you need a patch for an older version of openssl,  you should look
-+      to older OCF releases.  This patch is unlikely to work on older
-+      openssl versions.
-+
-+      openssl-0.9.8i.patch
-+                - enables --with-cryptodev for non BSD systems
-+                - adds -cpu option to openssl speed for calculating CPU load
-+                  under linux
-+                - fixes null pointer in openssl speed multi thread output.
-+                - fixes test keys to work with linux crypto's more stringent
-+                  key checking.
-+                - adds MD5/SHA acceleration (Ronen Shitrit), only enabled
-+                  with the --with-cryptodev-digests option
-+                - fixes bug in engine code caching.
-+
-+    * build crypto-tools-XXXXXXXX.tar.gz if you want to try some of the BSD
-+      tools for testing OCF (ie., cryptotest).
-+
-+How to load the OCF drivers
-+---------------------------
-+
-+    First insert the base modules:
-+
-+        insmod ocf
-+        insmod cryptodev
-+
-+    You can then install the software OCF driver with:
-+
-+        insmod cryptosoft
-+
-+    and one or more of the OCF HW drivers with:
-+
-+        insmod safe
-+        insmod hifn7751
-+        insmod ixp4xx
-+        ...
-+
-+    all the drivers take a debug option to enable verbose debug so that
-+    you can see what is going on.  For debug you load them as:
-+
-+        insmod ocf crypto_debug=1
-+        insmod cryptodev cryptodev_debug=1
-+        insmod cryptosoft swcr_debug=1
-+
-+    You may load more than one OCF crypto driver but then there is no guarantee
-+    as to which will be used.
-+
-+    You can also enable debug at run time on 2.6 systems with the following:
-+
-+        echo 1 > /sys/module/ocf/parameters/crypto_debug
-+        echo 1 > /sys/module/cryptodev/parameters/cryptodev_debug
-+        echo 1 > /sys/module/cryptosoft/parameters/swcr_debug
-+        echo 1 > /sys/module/hifn7751/parameters/hifn_debug
-+        echo 1 > /sys/module/safe/parameters/safe_debug
-+        echo 1 > /sys/module/ixp4xx/parameters/ixp_debug
-+        ...
-+
-+Testing the OCF support
-+-----------------------
-+
-+    run "cryptotest",  it should do a short test for a couple of
-+    des packets.  If it does everything is working.
-+
-+    If this works,  then ssh will use the driver when invoked as:
-+
-+        ssh -c 3des username@host
-+
-+    to see for sure that it is operating, enable debug as defined above.
-+
-+    To get a better idea of performance run:
-+
-+        cryptotest 100 4096
-+
-+    There are more options to cryptotest,  see the help.
-+
-+    It is also possible to use openssl to test the speed of the crypto
-+    drivers.
-+
-+        openssl speed -evp des -engine cryptodev -elapsed
-+        openssl speed -evp des3 -engine cryptodev -elapsed
-+        openssl speed -evp aes128 -engine cryptodev -elapsed
-+
-+    and multiple threads (10) with:
-+
-+        openssl speed -evp des -engine cryptodev -elapsed -multi 10
-+        openssl speed -evp des3 -engine cryptodev -elapsed -multi 10
-+        openssl speed -evp aes128 -engine cryptodev -elapsed -multi 10
-+
-+    for public key testing you can try:
-+
-+        cryptokeytest
-+        openssl speed -engine cryptodev rsa -elapsed
-+        openssl speed -engine cryptodev dsa -elapsed

-+ *  Flags is the bitwise "or" values for command configuration.  A single
-+ *  encrypt direction needs to be set:
-+ *
-+ *	HIFN_ENCODE or HIFN_DECODE
-+ *
-+ *  To use cryptography, a single crypto algorithm must be included:
-+ *
-+ *	HIFN_CRYPT_3DES or HIFN_CRYPT_DES
-+ *
-+ *  To use authentication is used, a single MAC algorithm must be included:
-+ *
-+ *	HIFN_MAC_MD5 or HIFN_MAC_SHA1
-+ *
-+ *  By default MD5 uses a 16 byte hash and SHA-1 uses a 20 byte hash.
-+ *  If the value below is set, hash values are truncated or assumed
-+ *  truncated to 12 bytes:
-+ *
-+ *	HIFN_MAC_TRUNC
-+ *
-+ *  Keys for encryption and authentication can be sent as part of a command,
-+ *  or the last key value used with a particular session can be retrieved
-+ *  and used again if either of these flags are not specified.
-+ *
-+ *	HIFN_CRYPT_NEW_KEY, HIFN_MAC_NEW_KEY
-+ *
-+ *  session_num
-+ *  -----------
-+ *  A number between 0 and 2048 (for DRAM models) or a number between 
-+ *  0 and 768 (for SRAM models).  Those who don't want to use session
-+ *  numbers should leave value at zero and send a new crypt key and/or
-+ *  new MAC key on every command.  If you use session numbers and
-+ *  don't send a key with a command, the last key sent for that same
-+ *  session number will be used.
-+ *
-+ *  Warning:  Using session numbers and multiboard at the same time

-+ *
-+ *  Blocking/Non-blocking Issues
-+ *  ============================
-+ *  The driver cannot block in hifn_crypto (no calls to tsleep) currently.
-+ *  hifn_crypto() returns HIFN_CRYPTO_RINGS_FULL if there is not enough
-+ *  room in any of the rings for the request to proceed.
-+ *
-+ *  Return Values
-+ *  =============
-+ *  0 for success, negative values on error
-+ *
-+ *  Defines for negative error codes are:
-+ *  
-+ *    HIFN_CRYPTO_BAD_INPUT  :  The passed in command had invalid settings.
-+ *    HIFN_CRYPTO_RINGS_FULL :  All DMA rings were full and non-blocking
-+ *                              behaviour was requested.

-+ * ---------------------------------------------------------------------------
-+ *
-+ * NOTES:
-+ *
-+ * The Freescale SEC (also known as 'talitos') resides on the
-+ * internal bus, and runs asynchronous to the processor core.  It has
-+ * a wide gamut of cryptographic acceleration features, including single-
-+ * pass IPsec (also known as algorithm chaining).  To properly utilize 
-+ * all of the SEC's performance enhancing features, further reworking 
-+ * of higher level code (framework, applications) will be necessary.
-+ *
-+ * The following table shows which SEC version is present in which devices:
-+ * 
-+ * Devices       SEC version
-+ *
-+ * 8272, 8248    SEC 1.0
-+ * 885, 875      SEC 1.2
-+ * 8555E, 8541E  SEC 2.0
-+ * 8349E         SEC 2.01
-+ * 8548E         SEC 2.1
-+ *
-+ * The following table shows the features offered by each SEC version:
-+ *
-+ * 	                       Max.   chan-
-+ * version  Bus I/F       Clock  nels  DEU AESU AFEU MDEU PKEU RNG KEU

-+ *
-+ * Each execution unit in the SEC has two modes of execution; channel and
-+ * slave/debug.  This driver employs the channel infrastructure in the
-+ * device for convenience.  Only the RNG is directly accessed due to the
-+ * convenience of its random fifo pool.  The relationship between the
-+ * channels and execution units is depicted in the following diagram:
-+ *
-+ *    -------   ------------
-+ * ---| ch0 |---|          |
-+ *    -------   |          |
-+ *              |          |------+-------+-------+-------+------------
-+ *    -------   |          |      |       |       |       |           |
-+ * ---| ch1 |---|          |      |       |       |       |           |

-+ *    -------   |          |
-+ * ---| ch3 |---|          |
-+ *    -------   ------------
-+ *
-+ * Channel ch0 may drive an aes operation to the aes unit (AESU),
-+ * and, at the same time, ch1 may drive a message digest operation
-+ * to the mdeu. Each channel has an input descriptor FIFO, and the 
-+ * FIFO can contain, e.g. on the 8541E, up to 24 entries, before a
-+ * a buffer overrun error is triggered. The controller is responsible
-+ * for fetching the data from descriptor pointers, and passing the 
-+ * data to the appropriate EUs. The controller also writes the 
-+ * cryptographic operation's result to memory. The SEC notifies 
-+ * completion by triggering an interrupt and/or setting the 1st byte 
-+ * of the hdr field to 0xff.
-+ *
-+ * TODO:
-+ * o support more algorithms
-+ * o support more versions of the SEC
-+ * o add support for linux 2.4
-+ * o scatter-gather (sg) support
-+ * o add support for public key ops (PKEU)
-+ * o add statistics

-+	default n
-+	depends on MTD_BLOCK

-+	select YAFFS_YAFFS2
-+	help
-+	  YAFFS2, or Yet Another Flash Filing System, is a filing system
-+	  optimised for NAND Flash chips.
-+
-+	  To compile the YAFFS2 file system support as a module, choose M
-+	  here: the module will be called yaffs2.
-+
-+	  If unsure, say N.
-+
-+	  Further information on YAFFS2 is available at
-+	  <http://www.aleph1.co.uk/yaffs/>.
-+
-+config YAFFS_YAFFS1
-+	bool "512 byte / page devices"
-+	depends on YAFFS_FS
-+	default y
-+	help
-+	  Enable YAFFS1 support -- yaffs for 512 byte / page devices
-+
-+	  Not needed for 2K-page devices.
-+
-+	  If unsure, say Y.
-+
-+config YAFFS_9BYTE_TAGS
-+	bool "Use older-style on-NAND data format with pageStatus byte"
-+	depends on YAFFS_YAFFS1
-+	default n
-+	help
-+
-+	  Older-style on-NAND data format has a "pageStatus" byte to record
-+	  chunk/page state.  This byte is zero when the page is discarded.
-+	  Choose this option if you have existing on-NAND data using this
-+	  format that you need to continue to support.  New data written
-+	  also uses the older-style format.  Note: Use of this option
-+	  generally requires that MTD's oob layout be adjusted to use the
-+	  older-style format.  See notes on tags formats and MTD versions
-+	  in yaffs_mtdif1.c.
-+
-+	  If unsure, say N.
-+
-+config YAFFS_DOES_ECC
-+	bool "Lets Yaffs do its own ECC"
-+	depends on YAFFS_FS && YAFFS_YAFFS1 && !YAFFS_9BYTE_TAGS
-+	default n
-+	help
-+	  This enables Yaffs to use its own ECC functions instead of using
-+	  the ones from the generic MTD-NAND driver.
-+
-+	  If unsure, say N.
-+
-+config YAFFS_ECC_WRONG_ORDER
-+	bool "Use the same ecc byte order as Steven Hill's nand_ecc.c"
-+	depends on YAFFS_FS && YAFFS_DOES_ECC && !YAFFS_9BYTE_TAGS
-+	default n
-+	help
-+	  This makes yaffs_ecc.c use the same ecc byte order as Steven
-+	  Hill's nand_ecc.c. If not set, then you get the same ecc byte
-+	  order as SmartMedia.
-+
-+	  If unsure, say N.
-+
-+config YAFFS_YAFFS2
-+	bool "2048 byte (or larger) / page devices"
-+	depends on YAFFS_FS
-+	default y
-+	help
-+	  Enable YAFFS2 support -- yaffs for >= 2K bytes per page devices
-+
-+	  If unsure, say Y.
-+
-+config YAFFS_AUTO_YAFFS2
-+	bool "Autoselect yaffs2 format"
-+	depends on YAFFS_YAFFS2
-+	default y
-+	help
-+	  Without this, you need to explicitely use yaffs2 as the file
-+	  system type. With this, you can say "yaffs" and yaffs or yaffs2
-+	  will be used depending on the device page size (yaffs on
-+	  512-byte page devices, yaffs2 on 2K page devices).
-+
-+	  If unsure, say Y.
-+
-+config YAFFS_DISABLE_LAZY_LOAD
-+	bool "Disable lazy loading"
-+	depends on YAFFS_YAFFS2
-+	default n
-+	help
-+	  "Lazy loading" defers loading file details until they are
-+	  required. This saves mount time, but makes the first look-up
-+	  a bit longer.
-+
-+	  Lazy loading will only happen if enabled by this option being 'n'
-+	  and if the appropriate tags are available, else yaffs2 will
-+	  automatically fall back to immediate loading and do the right
-+	  thing.
-+
-+	  Lazy laoding will be required by checkpointing.
-+
-+	  Setting this to 'y' will disable lazy loading.
-+
-+	  If unsure, say N.
-+
-+
-+config YAFFS_DISABLE_WIDE_TNODES
-+	bool "Turn off wide tnodes"
-+	depends on YAFFS_FS
-+	default n
-+	help
-+	  Wide tnodes are only used for NAND arrays >=32MB for 512-byte
-+	  page devices and >=128MB for 2k page devices. They use slightly
-+	  more RAM but are faster since they eliminate chunk group
-+	  searching.
-+
-+	  Setting this to 'y' will force tnode width to 16 bits and save
-+	  memory but make large arrays slower.
-+
-+	  If unsure, say N.
-+
-+config YAFFS_ALWAYS_CHECK_CHUNK_ERASED
-+	bool "Force chunk erase check"
-+	depends on YAFFS_FS
-+	default n
-+	help
-+          Normally YAFFS only checks chunks before writing until an erased
-+	  chunk is found. This helps to detect any partially written
-+	  chunks that might have happened due to power loss.
-+
-+	  Enabling this forces on the test that chunks are erased in flash
-+	  before writing to them. This takes more time but is potentially
-+	  a bit more secure.
-+
-+	  Suggest setting Y during development and ironing out driver
-+	  issues etc. Suggest setting to N if you want faster writing.
-+
-+	  If unsure, say Y.
-+
-+config YAFFS_SHORT_NAMES_IN_RAM
-+	bool "Cache short names in RAM"
-+	depends on YAFFS_FS
-+	default y
-+	help
-+	  If this config is set, then short names are stored with the
-+	  yaffs_Object.  This costs an extra 16 bytes of RAM per object,
-+	  but makes look-ups faster.
-+
-+	  If unsure, say Y.

-+	  will then be presented with several options that allow more precise

-+
-+	  The answer to this question won't directly affect the kernel:

-+
-+	  Note that your box can only act as a router if you enable IP

-+
-+	  echo "1" > /proc/sys/net/ipv4/ip_forward
-+
-+	  at boot time after the /proc file system has been mounted.
-+
-+	  If you turn on IP forwarding, you should consider the rp_filter, which
-+	  automatically rejects incoming packets if the routing table entry
-+	  for their source address doesn't match the network interface they're
-+	  arriving on. This has security advantages because it prevents the
-+	  so-called IP spoofing, however it can pose problems if you use
-+	  asymmetric routing (packets from you to a host take a different path
-+	  than packets from that host to you) or if you operate a non-routing
-+	  host which has several IP addresses on different interfaces. To turn

-+	  Normally, the kernel maintains an internal cache which maps IP

-+	  the physical networking layer. For small networks having a few

-+	  maintaining an internal ARP cache does not work well for very large
-+	  switched networks, and will use a lot of kernel memory if TCP/IP
-+	  connections are made to many machines on the network.
-+
-+	  If you say Y here, the kernel's internal ARP cache will never grow
-+	  to more than 256 entries (the oldest entries are expired in a LIFO
-+	  manner) and communication will be attempted with the user space ARP
-+	  daemon arpd. Arpd then answers the address resolution request either
-+	  from its own cache or by asking the net.
-+
-+	  This code is experimental and also obsolete. If you want to use it,

-+config SYN_COOKIES

-+	  users from being able to connect to your computer during an ongoing
-+	  attack and requires very little work from the attacker, who can
-+	  operate from anywhere on the Internet.
-+
-+	  SYN cookies provide protection against this type of attack. If you
-+	  say Y here, the TCP/IP stack will use a cryptographic challenge
-+	  protocol known as "SYN cookies" to enable legitimate users to
-+	  continue to connect, even when your machine is under attack. There
-+	  is no need for the legitimate users to change their TCP/IP software;
-+	  SYN cookies work transparently to them. For technical information
-+	  about SYN cookies, check out <http://cr.yp.to/syncookies.html>.
-+
-+	  If you are SYN flooded, the source address reported by the kernel is
-+	  likely to have been forged by the attacker; it is only reported as

-+ *  To use authentication is used, a single MAC algorithm must be included:
-+ *
-+ *	HIFN_MAC_MD5 or HIFN_MAC_SHA1
-+ *
-+ *  By default MD5 uses a 16 byte hash and SHA-1 uses a 20 byte hash.
-+ *  If the value below is set, hash values are truncated or assumed
-+ *  truncated to 12 bytes:
-+ *
-+ *	HIFN_MAC_TRUNC
-+ *
-+ *  Keys for encryption and authentication can be sent as part of a command,
-+ *  or the last key value used with a particular session can be retrieved
-+ *  and used again if either of these flags are not specified.
-+ *
-+ *	HIFN_CRYPT_NEW_KEY, HIFN_MAC_NEW_KEY
-+ *
-+ *  session_num
-+ *  -----------
-+ *  A number between 0 and 2048 (for DRAM models) or a number between 
-+ *  0 and 768 (for SRAM models).  Those who don't want to use session
-+ *  numbers should leave value at zero and send a new crypt key and/or
-+ *  new MAC key on every command.  If you use session numbers and
-+ *  don't send a key with a command, the last key sent for that same
-+ *  session number will be used.
-+ *
-+ *  Warning:  Using session numbers and multiboard at the same time
-+ *            is currently broken.
-+ *
-+ *  mbuf
-+ *  ----
-+ *  Either fill in the mbuf pointer and npa=0 or
-+ *	 fill packp[] and packl[] and set npa to > 0
-+ * 
-+ *  mac_header_skip
-+ *  ---------------
-+ *  The number of bytes of the source_buf that are skipped over before
-+ *  authentication begins.  This must be a number between 0 and 2^16-1
-+ *  and can be used by IPsec implementers to skip over IP headers.
-+ *  *** Value ignored if authentication not used ***
-+ *
-+ *  crypt_header_skip
-+ *  -----------------
-+ *  The number of bytes of the source_buf that are skipped over before
-+ *  the cryptographic operation begins.  This must be a number between 0
-+ *  and 2^16-1.  For IPsec, this number will always be 8 bytes larger
-+ *  than the auth_header_skip (to skip over the ESP header).
-+ *  *** Value ignored if cryptography not used ***

-+ *  Function:  hifn_crypto
-+ *
-+ *  Purpose:   Called by external drivers to begin an encryption on the
-+ *             HIFN board.
-+ *
-+ *  Blocking/Non-blocking Issues
-+ *  ============================
-+ *  The driver cannot block in hifn_crypto (no calls to tsleep) currently.
-+ *  hifn_crypto() returns HIFN_CRYPTO_RINGS_FULL if there is not enough
-+ *  room in any of the rings for the request to proceed.
-+ *
-+ *  Return Values
-+ *  =============
-+ *  0 for success, negative values on error
-+ *
-+ *  Defines for negative error codes are:
-+ *  
-+ *    HIFN_CRYPTO_BAD_INPUT  :  The passed in command had invalid settings.
-+ *    HIFN_CRYPTO_RINGS_FULL :  All DMA rings were full and non-blocking
-+ *                              behaviour was requested.

-+README - ocf-linux-20071215
-+---------------------------
-+
-+This README provides instructions for getting ocf-linux compiled and
-+operating in a generic linux environment.  For other information you
-+might like to visit the home page for this project:
-+
-+    http://ocf-linux.sourceforge.net/
-+
-+Adding OCF to linux
-+-------------------
-+
-+    Not much in this file for now,  just some notes.  I usually build
-+    the ocf support as modules but it can be built into the kernel as
-+    well.  To use it:
-+
-+    * mknod /dev/crypto c 10 70
-+
-+    * to add OCF to your kernel source,  you have two options.  Apply
-+      the kernel specific patch:
-+
-+          cd linux-2.4*; gunzip < ocf-linux-24-XXXXXXXX.patch.gz | patch -p1
-+          cd linux-2.6*; gunzip < ocf-linux-26-XXXXXXXX.patch.gz | patch -p1
-+    
-+      if you do one of the above,  then you can proceed to the next step,
-+      or you can do the above process by hand with using the patches against
-+      linux-2.4.35 and 2.6.23 to include the ocf code under crypto/ocf.
-+      Here's how to add it:
-+
-+      for 2.4.35 (and later)
-+
-+          cd linux-2.4.35/crypto
-+          tar xvzf ocf-linux.tar.gz
-+          cd ..
-+          patch -p1 < crypto/ocf/patches/linux-2.4.35-ocf.patch
-+
-+      for 2.6.23 (and later),  find the kernel patch specific (or nearest)
-+      to your kernel versions and then:
-+
-+          cd linux-2.6.NN/crypto
-+          tar xvzf ocf-linux.tar.gz
-+          cd ..
-+          patch -p1 < crypto/ocf/patches/linux-2.6.NN-ocf.patch
-+
-+      It should be easy to take this patch and apply it to other more
-+      recent versions of the kernels.  The same patches should also work
-+      relatively easily on kernels as old as 2.6.11 and 2.4.18.
-+      
-+    * under 2.4 if you are on a non-x86 platform,  you may need to:
-+
-+        cp linux-2.X.x/include/asm-i386/kmap_types.h linux-2.X.x/include/asm-YYY
-+
-+      so that you can build the kernel crypto support needed for the cryptosoft
-+      driver.
-+
-+    * For simplicity you should enable all the crypto support in your kernel
-+      except for the test driver.  Likewise for the OCF options.  Do not
-+      enable OCF crypto drivers for HW that you do not have (for example
-+      ixp4xx will not compile on non-Xscale systems).
-+
-+    * make sure that cryptodev.h (from ocf-linux.tar.gz) is installed as
-+      crypto/cryptodev.h in an include directory that is used for building
-+      applications for your platform.  For example on a host system that
-+      might be:
-+
-+              /usr/include/crypto/cryptodev.h
-+
-+    * patch your openssl-0.9.8i code with the openssl-0.9.8i.patch.
-+      (NOTE: there is no longer a need to patch ssh). The patch is against:
-+      openssl-0_9_8e
-+
-+      If you need a patch for an older version of openssl,  you should look
-+      to older OCF releases.  This patch is unlikely to work on older
-+      openssl versions.
-+
-+      openssl-0.9.8i.patch
-+                - enables --with-cryptodev for non BSD systems
-+                - adds -cpu option to openssl speed for calculating CPU load
-+                  under linux
-+                - fixes null pointer in openssl speed multi thread output.
-+                - fixes test keys to work with linux crypto's more stringent
-+                  key checking.
-+                - adds MD5/SHA acceleration (Ronen Shitrit), only enabled
-+                  with the --with-cryptodev-digests option
-+                - fixes bug in engine code caching.
-+
-+    * build crypto-tools-XXXXXXXX.tar.gz if you want to try some of the BSD
-+      tools for testing OCF (ie., cryptotest).
-+
-+How to load the OCF drivers
-+---------------------------
-+
-+    First insert the base modules:
-+
-+        insmod ocf
-+        insmod cryptodev
-+
-+    You can then install the software OCF driver with:
-+
-+        insmod cryptosoft
-+
-+    and one or more of the OCF HW drivers with:
-+
-+        insmod safe
-+        insmod hifn7751
-+        insmod ixp4xx
-+        ...
-+
-+    all the drivers take a debug option to enable verbose debug so that
-+    you can see what is going on.  For debug you load them as:
-+
-+        insmod ocf crypto_debug=1
-+        insmod cryptodev cryptodev_debug=1
-+        insmod cryptosoft swcr_debug=1
-+
-+    You may load more than one OCF crypto driver but then there is no guarantee
-+    as to which will be used.
-+
-+    You can also enable debug at run time on 2.6 systems with the following:
-+
-+        echo 1 > /sys/module/ocf/parameters/crypto_debug
-+        echo 1 > /sys/module/cryptodev/parameters/cryptodev_debug
-+        echo 1 > /sys/module/cryptosoft/parameters/swcr_debug
-+        echo 1 > /sys/module/hifn7751/parameters/hifn_debug
-+        echo 1 > /sys/module/safe/parameters/safe_debug
-+        echo 1 > /sys/module/ixp4xx/parameters/ixp_debug
-+        ...
-+
-+Testing the OCF support
-+-----------------------
-+
-+    run "cryptotest",  it should do a short test for a couple of
-+    des packets.  If it does everything is working.
-+
-+    If this works,  then ssh will use the driver when invoked as:
-+
-+        ssh -c 3des username@host
-+
-+    to see for sure that it is operating, enable debug as defined above.
-+
-+    To get a better idea of performance run:
-+
-+        cryptotest 100 4096
-+
-+    There are more options to cryptotest,  see the help.
-+
-+    It is also possible to use openssl to test the speed of the crypto
-+    drivers.
-+
-+        openssl speed -evp des -engine cryptodev -elapsed
-+        openssl speed -evp des3 -engine cryptodev -elapsed
-+        openssl speed -evp aes128 -engine cryptodev -elapsed
-+
-+    and multiple threads (10) with:
-+
-+        openssl speed -evp des -engine cryptodev -elapsed -multi 10
-+        openssl speed -evp des3 -engine cryptodev -elapsed -multi 10
-+        openssl speed -evp aes128 -engine cryptodev -elapsed -multi 10
-+
-+    for public key testing you can try:
-+
-+        cryptokeytest
-+        openssl speed -engine cryptodev rsa -elapsed
-+        openssl speed -engine cryptodev dsa -elapsed

-+ * ---------------------------------------------------------------------------
-+ *
-+ * NOTES:
-+ *
-+ * The Freescale SEC (also known as 'talitos') resides on the
-+ * internal bus, and runs asynchronous to the processor core.  It has
-+ * a wide gamut of cryptographic acceleration features, including single-
-+ * pass IPsec (also known as algorithm chaining).  To properly utilize 
-+ * all of the SEC's performance enhancing features, further reworking 
-+ * of higher level code (framework, applications) will be necessary.
-+ *
-+ * The following table shows which SEC version is present in which devices:
-+ * 
-+ * Devices       SEC version
-+ *
-+ * 8272, 8248    SEC 1.0
-+ * 885, 875      SEC 1.2
-+ * 8555E, 8541E  SEC 2.0
-+ * 8349E         SEC 2.01
-+ * 8548E         SEC 2.1
-+ *
-+ * The following table shows the features offered by each SEC version:
-+ *
-+ * 	                       Max.   chan-
-+ * version  Bus I/F       Clock  nels  DEU AESU AFEU MDEU PKEU RNG KEU

-+ *
-+ * Each execution unit in the SEC has two modes of execution; channel and
-+ * slave/debug.  This driver employs the channel infrastructure in the
-+ * device for convenience.  Only the RNG is directly accessed due to the
-+ * convenience of its random fifo pool.  The relationship between the
-+ * channels and execution units is depicted in the following diagram:
-+ *
-+ *    -------   ------------
-+ * ---| ch0 |---|          |
-+ *    -------   |          |
-+ *              |          |------+-------+-------+-------+------------
-+ *    -------   |          |      |       |       |       |           |
-+ * ---| ch1 |---|          |      |       |       |       |           |
-+ *    -------   |          |   ------  ------  ------  ------      ------
-+ *              |controller|   |DEU |  |AESU|  |MDEU|  |PKEU| ...  |RNG |
-+ *    -------   |          |   ------  ------  ------  ------      ------
-+ * ---| ch2 |---|          |      |       |       |       |           |
-+ *    -------   |          |      |       |       |       |           |
-+ *              |          |------+-------+-------+-------+------------
-+ *    -------   |          |
-+ * ---| ch3 |---|          |
-+ *    -------   ------------
-+ *
-+ * Channel ch0 may drive an aes operation to the aes unit (AESU),
-+ * and, at the same time, ch1 may drive a message digest operation
-+ * to the mdeu. Each channel has an input descriptor FIFO, and the 
-+ * FIFO can contain, e.g. on the 8541E, up to 24 entries, before a
-+ * a buffer overrun error is triggered. The controller is responsible
-+ * for fetching the data from descriptor pointers, and passing the 
-+ * data to the appropriate EUs. The controller also writes the 
-+ * cryptographic operation's result to memory. The SEC notifies 
-+ * completion by triggering an interrupt and/or setting the 1st byte 
-+ * of the hdr field to 0xff.
-+ *
-+ * TODO:
-+ * o support more algorithms
-+ * o support more versions of the SEC
-+ * o add support for linux 2.4
-+ * o scatter-gather (sg) support
-+ * o add support for public key ops (PKEU)
-+ * o add statistics

-+	help
-+	  YAFFS2, or Yet Another Flash Filing System, is a filing system
-+	  optimised for NAND Flash chips.
-+
-+	  To compile the YAFFS2 file system support as a module, choose M
-+	  here: the module will be called yaffs2.
-+
-+	  If unsure, say N.
-+
-+	  Further information on YAFFS2 is available at
-+	  <http://www.aleph1.co.uk/yaffs/>.
-+
-+config YAFFS_YAFFS1
-+	bool "512 byte / page devices"
-+	depends on YAFFS_FS
-+	default y
-+	help
-+	  Enable YAFFS1 support -- yaffs for 512 byte / page devices
-+
-+	  Not needed for 2K-page devices.
-+
-+	  If unsure, say Y.
-+
-+config YAFFS_9BYTE_TAGS
-+	bool "Use older-style on-NAND data format with pageStatus byte"
-+	depends on YAFFS_YAFFS1
-+	default n
-+	help
-+
-+	  Older-style on-NAND data format has a "pageStatus" byte to record
-+	  chunk/page state.  This byte is zero when the page is discarded.
-+	  Choose this option if you have existing on-NAND data using this
-+	  format that you need to continue to support.  New data written
-+	  also uses the older-style format.  Note: Use of this option
-+	  generally requires that MTD's oob layout be adjusted to use the
-+	  older-style format.  See notes on tags formats and MTD versions
-+	  in yaffs_mtdif1.c.
-+
-+	  If unsure, say N.
-+
-+config YAFFS_DOES_ECC
-+	bool "Lets Yaffs do its own ECC"
-+	depends on YAFFS_FS && YAFFS_YAFFS1 && !YAFFS_9BYTE_TAGS
-+	default n
-+	help
-+	  This enables Yaffs to use its own ECC functions instead of using
-+	  the ones from the generic MTD-NAND driver.
-+
-+	  If unsure, say N.
-+
-+config YAFFS_ECC_WRONG_ORDER
-+	bool "Use the same ecc byte order as Steven Hill's nand_ecc.c"
-+	depends on YAFFS_FS && YAFFS_DOES_ECC && !YAFFS_9BYTE_TAGS
-+	default n
-+	help
-+	  This makes yaffs_ecc.c use the same ecc byte order as Steven
-+	  Hill's nand_ecc.c. If not set, then you get the same ecc byte
-+	  order as SmartMedia.
-+
-+	  If unsure, say N.
-+
-+config YAFFS_YAFFS2
-+	bool "2048 byte (or larger) / page devices"
-+	depends on YAFFS_FS
-+	default y
-+	help
-+	  Enable YAFFS2 support -- yaffs for >= 2K bytes per page devices
-+
-+	  If unsure, say Y.
-+
-+config YAFFS_AUTO_YAFFS2
-+	bool "Autoselect yaffs2 format"
-+	depends on YAFFS_YAFFS2
-+	default y
-+	help
-+	  Without this, you need to explicitely use yaffs2 as the file
-+	  system type. With this, you can say "yaffs" and yaffs or yaffs2
-+	  will be used depending on the device page size (yaffs on
-+	  512-byte page devices, yaffs2 on 2K page devices).
-+
-+	  If unsure, say Y.
-+
-+config YAFFS_DISABLE_LAZY_LOAD
-+	bool "Disable lazy loading"
-+	depends on YAFFS_YAFFS2
-+	default n
-+	help
-+	  "Lazy loading" defers loading file details until they are
-+	  required. This saves mount time, but makes the first look-up
-+	  a bit longer.
-+
-+	  Lazy loading will only happen if enabled by this option being 'n'
-+	  and if the appropriate tags are available, else yaffs2 will
-+	  automatically fall back to immediate loading and do the right
-+	  thing.
-+
-+	  Lazy laoding will be required by checkpointing.
-+
-+	  Setting this to 'y' will disable lazy loading.
-+
-+	  If unsure, say N.
-+
-+
-+config YAFFS_DISABLE_WIDE_TNODES
-+	bool "Turn off wide tnodes"
-+	depends on YAFFS_FS
-+	default n
-+	help
-+	  Wide tnodes are only used for NAND arrays >=32MB for 512-byte
-+	  page devices and >=128MB for 2k page devices. They use slightly
-+	  more RAM but are faster since they eliminate chunk group
-+	  searching.
-+
-+	  Setting this to 'y' will force tnode width to 16 bits and save
-+	  memory but make large arrays slower.
-+
-+	  If unsure, say N.
-+
-+config YAFFS_ALWAYS_CHECK_CHUNK_ERASED
-+	bool "Force chunk erase check"
-+	depends on YAFFS_FS
-+	default n
-+	help
-+          Normally YAFFS only checks chunks before writing until an erased
-+	  chunk is found. This helps to detect any partially written
-+	  chunks that might have happened due to power loss.
-+
-+	  Enabling this forces on the test that chunks are erased in flash
-+	  before writing to them. This takes more time but is potentially
-+	  a bit more secure.
-+
-+	  Suggest setting Y during development and ironing out driver
-+	  issues etc. Suggest setting to N if you want faster writing.
-+
-+	  If unsure, say Y.
-+
-+config YAFFS_SHORT_NAMES_IN_RAM
-+	bool "Cache short names in RAM"
-+	depends on YAFFS_FS
-+	default y
-+	help
-+	  If this config is set, then short names are stored with the
-+	  yaffs_Object.  This costs an extra 16 bytes of RAM per object,
-+	  but makes look-ups faster.
-+
-+	  If unsure, say Y.

-+	help
-+	  This is code for addressing several networked computers at once,
-+	  enlarging your kernel by about 2 KB. You need multicasting if you
-+	  intend to participate in the MBONE, a high bandwidth network on top
-+	  of the Internet which carries audio and video broadcasts. More
-+	  information about the MBONE is on the WWW at
-+	  <http://www.savetz.com/mbone/>. Information about the multicast

-+
-+config IP_ADVANCED_ROUTER
-+	bool "IP: advanced router"
-+	---help---
-+	  If you intend to run your Linux box mostly as a router, i.e. as a
-+	  computer that forwards and redistributes network packets, say Y; you
-+	  will then be presented with several options that allow more precise
-+	  control about the routing process.
-+
-+	  The answer to this question won't directly affect the kernel:
-+	  answering N will just cause the configurator to skip all the
-+	  questions about advanced routing.
-+
-+	  Note that your box can only act as a router if you enable IP
-+	  forwarding in your kernel; you can do that by saying Y to "/proc
-+	  file system support" and "Sysctl support" below and executing the
-+	  line
-+
-+	  echo "1" > /proc/sys/net/ipv4/ip_forward
-+
-+	  at boot time after the /proc file system has been mounted.
-+
-+	  If you turn on IP forwarding, you should consider the rp_filter, which
-+	  automatically rejects incoming packets if the routing table entry
-+	  for their source address doesn't match the network interface they're
-+	  arriving on. This has security advantages because it prevents the
-+	  so-called IP spoofing, however it can pose problems if you use
-+	  asymmetric routing (packets from you to a host take a different path
-+	  than packets from that host to you) or if you operate a non-routing
-+	  host which has several IP addresses on different interfaces. To turn
-+	  rp_filter on use:
-+
-+	  echo 1 > /proc/sys/net/ipv4/conf/<device>/rp_filter
-+	   and
-+	  echo 1 > /proc/sys/net/ipv4/conf/all/rp_filter
-+
-+	  Note that some distributions enable it in startup scripts.
-+	  For details about rp_filter strict and loose mode read

-+	  operate from anywhere on the Internet.
-+
-+	  SYN cookies provide protection against this type of attack. If you
-+	  say Y here, the TCP/IP stack will use a cryptographic challenge
-+	  protocol known as "SYN cookies" to enable legitimate users to
-+	  continue to connect, even when your machine is under attack. There
-+	  is no need for the legitimate users to change their TCP/IP software;
-+	  SYN cookies work transparently to them. For technical information
-+	  about SYN cookies, check out <http://cr.yp.to/syncookies.html>.
-+
-+	  If you are SYN flooded, the source address reported by the kernel is

-+ * INET		An implementation of the TCP/IP protocol suite for the LINUX
-+ *		operating system.  INET is implemented using the  BSD Socket
-+ *		interface as the means of communication with the user level.
-+ *
-+ *		The User Datagram Protocol (UDP).
-+ *
-+ * Authors:	Ross Biro
-+ *		Fred N. van Kempen, <waltje@uWalt.NL.Mugnet.ORG>
-+ *		Arnt Gulbrandsen, <agulbra@nvg.unit.no>
-+ *		Alan Cox, <alan@lxorguk.ukuu.org.uk>
-+ *		Hirokazu Takahashi, <taka@valinux.co.jp>
-+ *
-+ * Fixes:
-+ *		Alan Cox	:	verify_area() calls
-+ *		Alan Cox	: 	stopped close while in use off icmp
-+ *					messages. Not a fix but a botch that
-+ *					for udp at least is 'valid'.
-+ *		Alan Cox	:	Fixed icmp handling properly
-+ *		Alan Cox	: 	Correct error for oversized datagrams
-+ *		Alan Cox	:	Tidied select() semantics.
-+ *		Alan Cox	:	udp_err() fixed properly, also now
-+ *					select and read wake correctly on errors
-+ *		Alan Cox	:	udp_send verify_area moved to avoid mem leak
-+ *		Alan Cox	:	UDP can count its memory
-+ *		Alan Cox	:	send to an unknown connection causes
-+ *					an ECONNREFUSED off the icmp, but
-+ *					does NOT close.
-+ *		Alan Cox	:	Switched to new sk_buff handlers. No more backlog!
-+ *		Alan Cox	:	Using generic datagram code. Even smaller and the PEEK
-+ *					bug no longer crashes it.
-+ *		Fred Van Kempen	: 	Net2e support for sk->broadcast.
-+ *		Alan Cox	:	Uses skb_free_datagram
-+ *		Alan Cox	:	Added get/set sockopt support.
-+ *		Alan Cox	:	Broadcasting without option set returns EACCES.
-+ *		Alan Cox	:	No wakeup calls. Instead we now use the callbacks.
-+ *		Alan Cox	:	Use ip_tos and ip_ttl
-+ *		Alan Cox	:	SNMP Mibs
-+ *		Alan Cox	:	MSG_DONTROUTE, and 0.0.0.0 support.
-+ *		Matt Dillon	:	UDP length checks.
-+ *		Alan Cox	:	Smarter af_inet used properly.
-+ *		Alan Cox	:	Use new kernel side addressing.
-+ *		Alan Cox	:	Incorrect return on truncated datagram receive.
-+ *	Arnt Gulbrandsen 	:	New udp_send and stuff
-+ *		Alan Cox	:	Cache last socket
-+ *		Alan Cox	:	Route cache
-+ *		Jon Peatfield	:	Minor efficiency fix to sendto().
-+ *		Mike Shaver	:	RFC1122 checks.
-+ *		Alan Cox	:	Nonblocking error fix.
-+ *	Willy Konynenberg	:	Transparent proxying support.
-+ *		Mike McLagan	:	Routing by source
-+ *		David S. Miller	:	New socket lookup architecture.
-+ *					Last socket cache retained as it
-+ *					does have a high hit rate.
-+ *		Olaf Kirch	:	Don't linearise iovec on sendmsg.
-+ *		Andi Kleen	:	Some cleanups, cache destination entry
-+ *					for connect.
-+ *	Vitaly E. Lavrov	:	Transparent proxy revived after year coma.
-+ *		Melvin Smith	:	Check msg_name not msg_namelen in sendto(),
-+ *					return ENOTCONN for unconnected sockets (POSIX)
-+ *		Janos Farkas	:	don't deliver multi/broadcasts to a different
-+ *					bound-to-device socket
-+ *	Hirokazu Takahashi	:	HW checksumming for outgoing UDP
-+ *					datagrams.
-+ *	Hirokazu Takahashi	:	sendfile() on UDP works now.
-+ *		Arnaldo C. Melo :	convert /proc/net/udp to seq_file
-+ *	YOSHIFUJI Hideaki @USAGI and:	Support IPV6_V6ONLY socket option, which
-+ *	Alexey Kuznetsov:		allow both IPv4 and IPv6 sockets to bind
-+ *					a single port at the same time.
-+ *	Derek Atkins <derek@ihtfp.com>: Add Encapulation Support
-+ *	James Chapman		:	Add L2TP encapsulation type.

-+ *  Flags is the bitwise "or" values for command configuration.  A single
-+ *  encrypt direction needs to be set:
-+ *
-+ *	HIFN_ENCODE or HIFN_DECODE
-+ *
-+ *  To use cryptography, a single crypto algorithm must be included:
-+ *
-+ *	HIFN_CRYPT_3DES or HIFN_CRYPT_DES
-+ *
-+ *  To use authentication is used, a single MAC algorithm must be included:
-+ *
-+ *	HIFN_MAC_MD5 or HIFN_MAC_SHA1
-+ *
-+ *  By default MD5 uses a 16 byte hash and SHA-1 uses a 20 byte hash.
-+ *  If the value below is set, hash values are truncated or assumed
-+ *  truncated to 12 bytes:
-+ *
-+ *	HIFN_MAC_TRUNC
-+ *
-+ *  Keys for encryption and authentication can be sent as part of a command,
-+ *  or the last key value used with a particular session can be retrieved
-+ *  and used again if either of these flags are not specified.
-+ *
-+ *	HIFN_CRYPT_NEW_KEY, HIFN_MAC_NEW_KEY
-+ *
-+ *  session_num
-+ *  -----------
-+ *  A number between 0 and 2048 (for DRAM models) or a number between 
-+ *  0 and 768 (for SRAM models).  Those who don't want to use session
-+ *  numbers should leave value at zero and send a new crypt key and/or
-+ *  new MAC key on every command.  If you use session numbers and
-+ *  don't send a key with a command, the last key sent for that same
-+ *  session number will be used.
-+ *
-+ *  Warning:  Using session numbers and multiboard at the same time
-+ *            is currently broken.

-+ *  The number of bytes of the source_buf that are skipped over before

-+ *
-+ *  crypt_header_skip
-+ *  -----------------
-+ *  The number of bytes of the source_buf that are skipped over before
-+ *  the cryptographic operation begins.  This must be a number between 0
-+ *  and 2^16-1.  For IPsec, this number will always be 8 bytes larger

-+ *  Purpose:   Called by external drivers to begin an encryption on the

-+ *
-+ *  Blocking/Non-blocking Issues
-+ *  ============================
-+ *  The driver cannot block in hifn_crypto (no calls to tsleep) currently.
-+ *  hifn_crypto() returns HIFN_CRYPTO_RINGS_FULL if there is not enough
-+ *  room in any of the rings for the request to proceed.
-+ *
-+ *  Return Values
-+ *  =============
-+ *  0 for success, negative values on error
-+ *
-+ *  Defines for negative error codes are:
-+ *  
-+ *    HIFN_CRYPTO_BAD_INPUT  :  The passed in command had invalid settings.
-+ *    HIFN_CRYPTO_RINGS_FULL :  All DMA rings were full and non-blocking
-+ *                              behaviour was requested.

-+README - ocf-linux-20071215
-+---------------------------
-+
-+This README provides instructions for getting ocf-linux compiled and
-+operating in a generic linux environment.  For other information you
-+might like to visit the home page for this project:
-+
-+    http://ocf-linux.sourceforge.net/
-+
-+Adding OCF to linux
-+-------------------
-+
-+    Not much in this file for now,  just some notes.  I usually build
-+    the ocf support as modules but it can be built into the kernel as
-+    well.  To use it:
-+
-+    * mknod /dev/crypto c 10 70
-+
-+    * to add OCF to your kernel source,  you have two options.  Apply
-+      the kernel specific patch:
-+
-+          cd linux-2.4*; gunzip < ocf-linux-24-XXXXXXXX.patch.gz | patch -p1
-+          cd linux-2.6*; gunzip < ocf-linux-26-XXXXXXXX.patch.gz | patch -p1
-+    
-+      if you do one of the above,  then you can proceed to the next step,
-+      or you can do the above process by hand with using the patches against
-+      linux-2.4.35 and 2.6.23 to include the ocf code under crypto/ocf.
-+      Here's how to add it:
-+
-+      for 2.4.35 (and later)
-+
-+          cd linux-2.4.35/crypto
-+          tar xvzf ocf-linux.tar.gz
-+          cd ..
-+          patch -p1 < crypto/ocf/patches/linux-2.4.35-ocf.patch
-+
-+      for 2.6.23 (and later),  find the kernel patch specific (or nearest)
-+      to your kernel versions and then:
-+
-+          cd linux-2.6.NN/crypto
-+          tar xvzf ocf-linux.tar.gz
-+          cd ..
-+          patch -p1 < crypto/ocf/patches/linux-2.6.NN-ocf.patch
-+
-+      It should be easy to take this patch and apply it to other more
-+      recent versions of the kernels.  The same patches should also work
-+      relatively easily on kernels as old as 2.6.11 and 2.4.18.
-+      
-+    * under 2.4 if you are on a non-x86 platform,  you may need to:
-+
-+        cp linux-2.X.x/include/asm-i386/kmap_types.h linux-2.X.x/include/asm-YYY
-+
-+      so that you can build the kernel crypto support needed for the cryptosoft
-+      driver.
-+
-+    * For simplicity you should enable all the crypto support in your kernel
-+      except for the test driver.  Likewise for the OCF options.  Do not
-+      enable OCF crypto drivers for HW that you do not have (for example
-+      ixp4xx will not compile on non-Xscale systems).
-+
-+    * make sure that cryptodev.h (from ocf-linux.tar.gz) is installed as
-+      crypto/cryptodev.h in an include directory that is used for building
-+      applications for your platform.  For example on a host system that
-+      might be:
-+
-+              /usr/include/crypto/cryptodev.h
-+
-+    * patch your openssl-0.9.8i code with the openssl-0.9.8i.patch.
-+      (NOTE: there is no longer a need to patch ssh). The patch is against:
-+      openssl-0_9_8e
-+
-+      If you need a patch for an older version of openssl,  you should look
-+      to older OCF releases.  This patch is unlikely to work on older
-+      openssl versions.
-+
-+      openssl-0.9.8i.patch
-+                - enables --with-cryptodev for non BSD systems
-+                - adds -cpu option to openssl speed for calculating CPU load
-+                  under linux
-+                - fixes null pointer in openssl speed multi thread output.
-+                - fixes test keys to work with linux crypto's more stringent
-+                  key checking.
-+                - adds MD5/SHA acceleration (Ronen Shitrit), only enabled
-+                  with the --with-cryptodev-digests option
-+                - fixes bug in engine code caching.
-+
-+    * build crypto-tools-XXXXXXXX.tar.gz if you want to try some of the BSD
-+      tools for testing OCF (ie., cryptotest).
-+
-+How to load the OCF drivers
-+---------------------------
-+
-+    First insert the base modules:
-+
-+        insmod ocf
-+        insmod cryptodev
-+
-+    You can then install the software OCF driver with:
-+
-+        insmod cryptosoft
-+
-+    and one or more of the OCF HW drivers with:
-+
-+        insmod safe
-+        insmod hifn7751
-+        insmod ixp4xx
-+        ...
-+
-+    all the drivers take a debug option to enable verbose debug so that
-+    you can see what is going on.  For debug you load them as:
-+
-+        insmod ocf crypto_debug=1
-+        insmod cryptodev cryptodev_debug=1
-+        insmod cryptosoft swcr_debug=1
-+
-+    You may load more than one OCF crypto driver but then there is no guarantee
-+    as to which will be used.
-+
-+    You can also enable debug at run time on 2.6 systems with the following:
-+
-+        echo 1 > /sys/module/ocf/parameters/crypto_debug
-+        echo 1 > /sys/module/cryptodev/parameters/cryptodev_debug
-+        echo 1 > /sys/module/cryptosoft/parameters/swcr_debug
-+        echo 1 > /sys/module/hifn7751/parameters/hifn_debug
-+        echo 1 > /sys/module/safe/parameters/safe_debug
-+        echo 1 > /sys/module/ixp4xx/parameters/ixp_debug
-+        ...
-+
-+Testing the OCF support
-+-----------------------
-+
-+    run "cryptotest",  it should do a short test for a couple of
-+    des packets.  If it does everything is working.
-+
-+    If this works,  then ssh will use the driver when invoked as:
-+
-+        ssh -c 3des username@host
-+
-+    to see for sure that it is operating, enable debug as defined above.
-+
-+    To get a better idea of performance run:
-+
-+        cryptotest 100 4096
-+
-+    There are more options to cryptotest,  see the help.
-+
-+    It is also possible to use openssl to test the speed of the crypto
-+    drivers.
-+
-+        openssl speed -evp des -engine cryptodev -elapsed
-+        openssl speed -evp des3 -engine cryptodev -elapsed
-+        openssl speed -evp aes128 -engine cryptodev -elapsed
-+
-+    and multiple threads (10) with:
-+
-+        openssl speed -evp des -engine cryptodev -elapsed -multi 10
-+        openssl speed -evp des3 -engine cryptodev -elapsed -multi 10
-+        openssl speed -evp aes128 -engine cryptodev -elapsed -multi 10
-+
-+    for public key testing you can try:
-+
-+        cryptokeytest
-+        openssl speed -engine cryptodev rsa -elapsed
-+        openssl speed -engine cryptodev dsa -elapsed

-+ * ---------------------------------------------------------------------------
-+ *
-+ * NOTES:
-+ *
-+ * The Freescale SEC (also known as 'talitos') resides on the
-+ * internal bus, and runs asynchronous to the processor core.  It has
-+ * a wide gamut of cryptographic acceleration features, including single-
-+ * pass IPsec (also known as algorithm chaining).  To properly utilize 
-+ * all of the SEC's performance enhancing features, further reworking 
-+ * of higher level code (framework, applications) will be necessary.
-+ *
-+ * The following table shows which SEC version is present in which devices:
-+ * 
-+ * Devices       SEC version
-+ *
-+ * 8272, 8248    SEC 1.0
-+ * 885, 875      SEC 1.2
-+ * 8555E, 8541E  SEC 2.0
-+ * 8349E         SEC 2.01
-+ * 8548E         SEC 2.1
-+ *
-+ * The following table shows the features offered by each SEC version:
-+ *
-+ * 	                       Max.   chan-
-+ * version  Bus I/F       Clock  nels  DEU AESU AFEU MDEU PKEU RNG KEU

-+ * SEC 1.2  internal 32b   66MHz   1     1    1    0    1    0   0   0
-+ * SEC 2.0  internal 64b  166MHz   4     1    1    1    1    1   1   0
-+ * SEC 2.01 internal 64b  166MHz   4     1    1    1    1    1   1   0
-+ * SEC 2.1  internal 64b  333MHz   4     1    1    1    1    1   1   1
-+ *
-+ * Each execution unit in the SEC has two modes of execution; channel and
-+ * slave/debug.  This driver employs the channel infrastructure in the
-+ * device for convenience.  Only the RNG is directly accessed due to the
-+ * convenience of its random fifo pool.  The relationship between the
-+ * channels and execution units is depicted in the following diagram:
-+ *
-+ *    -------   ------------
-+ * ---| ch0 |---|          |
-+ *    -------   |          |
-+ *              |          |------+-------+-------+-------+------------
-+ *    -------   |          |      |       |       |       |           |
-+ * ---| ch1 |---|          |      |       |       |       |           |
-+ *    -------   |          |   ------  ------  ------  ------      ------
-+ *              |controller|   |DEU |  |AESU|  |MDEU|  |PKEU| ...  |RNG |

-+ * ---| ch2 |---|          |      |       |       |       |           |
-+ *    -------   |          |      |       |       |       |           |
-+ *              |          |------+-------+-------+-------+------------
-+ *    -------   |          |
-+ * ---| ch3 |---|          |
-+ *    -------   ------------
-+ *
-+ * Channel ch0 may drive an aes operation to the aes unit (AESU),
-+ * and, at the same time, ch1 may drive a message digest operation
-+ * to the mdeu. Each channel has an input descriptor FIFO, and the 
-+ * FIFO can contain, e.g. on the 8541E, up to 24 entries, before a
-+ * a buffer overrun error is triggered. The controller is responsible
-+ * for fetching the data from descriptor pointers, and passing the 
-+ * data to the appropriate EUs. The controller also writes the 
-+ * cryptographic operation's result to memory. The SEC notifies 
-+ * completion by triggering an interrupt and/or setting the 1st byte 
-+ * of the hdr field to 0xff.
-+ *
-+ * TODO:
-+ * o support more algorithms
-+ * o support more versions of the SEC
-+ * o add support for linux 2.4
-+ * o scatter-gather (sg) support
-+ * o add support for public key ops (PKEU)
-+ * o add statistics

-+	  YAFFS2, or Yet Another Flash Filing System, is a filing system
-+	  optimised for NAND Flash chips.
-+
-+	  To compile the YAFFS2 file system support as a module, choose M
-+	  here: the module will be called yaffs2.
-+
-+	  If unsure, say N.
-+
-+	  Further information on YAFFS2 is available at

-+	depends on YAFFS_FS
-+	default y
-+	help
-+	  Enable YAFFS1 support -- yaffs for 512 byte / page devices
-+
-+	  Not needed for 2K-page devices.
-+
-+	  If unsure, say Y.
-+
-+config YAFFS_9BYTE_TAGS
-+	bool "Use older-style on-NAND data format with pageStatus byte"
-+	depends on YAFFS_YAFFS1
-+	default n
-+	help
-+
-+	  Older-style on-NAND data format has a "pageStatus" byte to record
-+	  chunk/page state.  This byte is zero when the page is discarded.
-+	  Choose this option if you have existing on-NAND data using this
-+	  format that you need to continue to support.  New data written
-+	  also uses the older-style format.  Note: Use of this option
-+	  generally requires that MTD's oob layout be adjusted to use the
-+	  older-style format.  See notes on tags formats and MTD versions
-+	  in yaffs_mtdif1.c.
-+
-+	  If unsure, say N.
-+
-+config YAFFS_DOES_ECC
-+	bool "Lets Yaffs do its own ECC"
-+	depends on YAFFS_FS && YAFFS_YAFFS1 && !YAFFS_9BYTE_TAGS
-+	default n
-+	help
-+	  This enables Yaffs to use its own ECC functions instead of using
-+	  the ones from the generic MTD-NAND driver.
-+
-+	  If unsure, say N.
-+
-+config YAFFS_ECC_WRONG_ORDER
-+	bool "Use the same ecc byte order as Steven Hill's nand_ecc.c"
-+	depends on YAFFS_FS && YAFFS_DOES_ECC && !YAFFS_9BYTE_TAGS
-+	default n
-+	help
-+	  This makes yaffs_ecc.c use the same ecc byte order as Steven
-+	  Hill's nand_ecc.c. If not set, then you get the same ecc byte
-+	  order as SmartMedia.
-+
-+	  If unsure, say N.
-+
-+config YAFFS_YAFFS2
-+	bool "2048 byte (or larger) / page devices"
-+	depends on YAFFS_FS
-+	default y
-+	help
-+	  Enable YAFFS2 support -- yaffs for >= 2K bytes per page devices

-+
-+config YAFFS_AUTO_YAFFS2
-+	bool "Autoselect yaffs2 format"
-+	depends on YAFFS_YAFFS2
-+	default y
-+	help
-+	  Without this, you need to explicitely use yaffs2 as the file
-+	  system type. With this, you can say "yaffs" and yaffs or yaffs2
-+	  will be used depending on the device page size (yaffs on
-+	  512-byte page devices, yaffs2 on 2K page devices).
-+
-+	  If unsure, say Y.
-+
-+config YAFFS_DISABLE_LAZY_LOAD
-+	bool "Disable lazy loading"
-+	depends on YAFFS_YAFFS2
-+	default n
-+	help
-+	  "Lazy loading" defers loading file details until they are
-+	  required. This saves mount time, but makes the first look-up
-+	  a bit longer.
-+
-+	  Lazy loading will only happen if enabled by this option being 'n'
-+	  and if the appropriate tags are available, else yaffs2 will
-+	  automatically fall back to immediate loading and do the right
-+	  thing.
-+
-+	  Lazy laoding will be required by checkpointing.
-+
-+	  Setting this to 'y' will disable lazy loading.
-+
-+	  If unsure, say N.
-+
-+
-+config YAFFS_DISABLE_WIDE_TNODES
-+	bool "Turn off wide tnodes"
-+	depends on YAFFS_FS
-+	default n
-+	help
-+	  Wide tnodes are only used for NAND arrays >=32MB for 512-byte
-+	  page devices and >=128MB for 2k page devices. They use slightly
-+	  more RAM but are faster since they eliminate chunk group
-+	  searching.
-+
-+	  Setting this to 'y' will force tnode width to 16 bits and save
-+	  memory but make large arrays slower.
-+
-+	  If unsure, say N.
-+
-+config YAFFS_ALWAYS_CHECK_CHUNK_ERASED
-+	bool "Force chunk erase check"
-+	depends on YAFFS_FS
-+	default n
-+	help
-+          Normally YAFFS only checks chunks before writing until an erased
-+	  chunk is found. This helps to detect any partially written
-+	  chunks that might have happened due to power loss.
-+
-+	  Enabling this forces on the test that chunks are erased in flash
-+	  before writing to them. This takes more time but is potentially
-+	  a bit more secure.
-+
-+	  Suggest setting Y during development and ironing out driver
-+	  issues etc. Suggest setting to N if you want faster writing.
-+
-+	  If unsure, say Y.
-+
-+config YAFFS_SHORT_NAMES_IN_RAM
-+	bool "Cache short names in RAM"
-+	depends on YAFFS_FS
-+	default y
-+	help
-+	  If this config is set, then short names are stored with the
-+	  yaffs_Object.  This costs an extra 16 bytes of RAM per object,
-+	  but makes look-ups faster.
-+
-+	  If unsure, say Y.

-+ *  Flags is the bitwise "or" values for command configuration.  A single
-+ *  encrypt direction needs to be set:
-+ *
-+ *	HIFN_ENCODE or HIFN_DECODE
-+ *
-+ *  To use cryptography, a single crypto algorithm must be included:
-+ *
-+ *	HIFN_CRYPT_3DES or HIFN_CRYPT_DES
-+ *
-+ *  To use authentication is used, a single MAC algorithm must be included:
-+ *
-+ *	HIFN_MAC_MD5 or HIFN_MAC_SHA1
-+ *
-+ *  By default MD5 uses a 16 byte hash and SHA-1 uses a 20 byte hash.
-+ *  If the value below is set, hash values are truncated or assumed
-+ *  truncated to 12 bytes:
-+ *
-+ *	HIFN_MAC_TRUNC
-+ *
-+ *  Keys for encryption and authentication can be sent as part of a command,
-+ *  or the last key value used with a particular session can be retrieved
-+ *  and used again if either of these flags are not specified.
-+ *
-+ *	HIFN_CRYPT_NEW_KEY, HIFN_MAC_NEW_KEY
-+ *
-+ *  session_num
-+ *  -----------
-+ *  A number between 0 and 2048 (for DRAM models) or a number between 
-+ *  0 and 768 (for SRAM models).  Those who don't want to use session
-+ *  numbers should leave value at zero and send a new crypt key and/or
-+ *  new MAC key on every command.  If you use session numbers and
-+ *  don't send a key with a command, the last key sent for that same
-+ *  session number will be used.
-+ *
-+ *  Warning:  Using session numbers and multiboard at the same time
-+ *            is currently broken.

-+ *  The number of bytes of the source_buf that are skipped over before

-+ *
-+ *  crypt_header_skip
-+ *  -----------------
-+ *  The number of bytes of the source_buf that are skipped over before
-+ *  the cryptographic operation begins.  This must be a number between 0
-+ *  and 2^16-1.  For IPsec, this number will always be 8 bytes larger

-+ *  Purpose:   Called by external drivers to begin an encryption on the

-+ *
-+ *  Blocking/Non-blocking Issues
-+ *  ============================
-+ *  The driver cannot block in hifn_crypto (no calls to tsleep) currently.
-+ *  hifn_crypto() returns HIFN_CRYPTO_RINGS_FULL if there is not enough
-+ *  room in any of the rings for the request to proceed.
-+ *
-+ *  Return Values
-+ *  =============
-+ *  0 for success, negative values on error
-+ *
-+ *  Defines for negative error codes are:
-+ *  
-+ *    HIFN_CRYPTO_BAD_INPUT  :  The passed in command had invalid settings.
-+ *    HIFN_CRYPTO_RINGS_FULL :  All DMA rings were full and non-blocking
-+ *                              behaviour was requested.

-+README - ocf-linux-20071215
-+---------------------------
-+
-+This README provides instructions for getting ocf-linux compiled and
-+operating in a generic linux environment.  For other information you
-+might like to visit the home page for this project:
-+
-+    http://ocf-linux.sourceforge.net/
-+
-+Adding OCF to linux
-+-------------------
-+
-+    Not much in this file for now,  just some notes.  I usually build
-+    the ocf support as modules but it can be built into the kernel as
-+    well.  To use it:
-+
-+    * mknod /dev/crypto c 10 70
-+
-+    * to add OCF to your kernel source,  you have two options.  Apply
-+      the kernel specific patch:
-+
-+          cd linux-2.4*; gunzip < ocf-linux-24-XXXXXXXX.patch.gz | patch -p1
-+          cd linux-2.6*; gunzip < ocf-linux-26-XXXXXXXX.patch.gz | patch -p1
-+    
-+      if you do one of the above,  then you can proceed to the next step,
-+      or you can do the above process by hand with using the patches against
-+      linux-2.4.35 and 2.6.23 to include the ocf code under crypto/ocf.
-+      Here's how to add it:
-+
-+      for 2.4.35 (and later)
-+
-+          cd linux-2.4.35/crypto
-+          tar xvzf ocf-linux.tar.gz
-+          cd ..
-+          patch -p1 < crypto/ocf/patches/linux-2.4.35-ocf.patch
-+
-+      for 2.6.23 (and later),  find the kernel patch specific (or nearest)
-+      to your kernel versions and then:
-+
-+          cd linux-2.6.NN/crypto
-+          tar xvzf ocf-linux.tar.gz
-+          cd ..
-+          patch -p1 < crypto/ocf/patches/linux-2.6.NN-ocf.patch
-+
-+      It should be easy to take this patch and apply it to other more
-+      recent versions of the kernels.  The same patches should also work
-+      relatively easily on kernels as old as 2.6.11 and 2.4.18.
-+      
-+    * under 2.4 if you are on a non-x86 platform,  you may need to:
-+
-+        cp linux-2.X.x/include/asm-i386/kmap_types.h linux-2.X.x/include/asm-YYY
-+
-+      so that you can build the kernel crypto support needed for the cryptosoft
-+      driver.
-+
-+    * For simplicity you should enable all the crypto support in your kernel
-+      except for the test driver.  Likewise for the OCF options.  Do not
-+      enable OCF crypto drivers for HW that you do not have (for example
-+      ixp4xx will not compile on non-Xscale systems).
-+
-+    * make sure that cryptodev.h (from ocf-linux.tar.gz) is installed as
-+      crypto/cryptodev.h in an include directory that is used for building
-+      applications for your platform.  For example on a host system that
-+      might be:
-+
-+              /usr/include/crypto/cryptodev.h
-+
-+    * patch your openssl-0.9.8i code with the openssl-0.9.8i.patch.
-+      (NOTE: there is no longer a need to patch ssh). The patch is against:
-+      openssl-0_9_8e
-+
-+      If you need a patch for an older version of openssl,  you should look
-+      to older OCF releases.  This patch is unlikely to work on older
-+      openssl versions.
-+
-+      openssl-0.9.8i.patch
-+                - enables --with-cryptodev for non BSD systems
-+                - adds -cpu option to openssl speed for calculating CPU load
-+                  under linux
-+                - fixes null pointer in openssl speed multi thread output.
-+                - fixes test keys to work with linux crypto's more stringent
-+                  key checking.
-+                - adds MD5/SHA acceleration (Ronen Shitrit), only enabled
-+                  with the --with-cryptodev-digests option
-+                - fixes bug in engine code caching.
-+
-+    * build crypto-tools-XXXXXXXX.tar.gz if you want to try some of the BSD
-+      tools for testing OCF (ie., cryptotest).
-+
-+How to load the OCF drivers
-+---------------------------
-+
-+    First insert the base modules:
-+
-+        insmod ocf
-+        insmod cryptodev
-+
-+    You can then install the software OCF driver with:
-+
-+        insmod cryptosoft
-+
-+    and one or more of the OCF HW drivers with:
-+
-+        insmod safe
-+        insmod hifn7751
-+        insmod ixp4xx
-+        ...
-+
-+    all the drivers take a debug option to enable verbose debug so that
-+    you can see what is going on.  For debug you load them as:
-+
-+        insmod ocf crypto_debug=1
-+        insmod cryptodev cryptodev_debug=1
-+        insmod cryptosoft swcr_debug=1
-+
-+    You may load more than one OCF crypto driver but then there is no guarantee
-+    as to which will be used.
-+
-+    You can also enable debug at run time on 2.6 systems with the following:
-+
-+        echo 1 > /sys/module/ocf/parameters/crypto_debug
-+        echo 1 > /sys/module/cryptodev/parameters/cryptodev_debug
-+        echo 1 > /sys/module/cryptosoft/parameters/swcr_debug
-+        echo 1 > /sys/module/hifn7751/parameters/hifn_debug
-+        echo 1 > /sys/module/safe/parameters/safe_debug
-+        echo 1 > /sys/module/ixp4xx/parameters/ixp_debug
-+        ...
-+
-+Testing the OCF support
-+-----------------------
-+
-+    run "cryptotest",  it should do a short test for a couple of
-+    des packets.  If it does everything is working.
-+
-+    If this works,  then ssh will use the driver when invoked as:
-+
-+        ssh -c 3des username@host
-+
-+    to see for sure that it is operating, enable debug as defined above.
-+
-+    To get a better idea of performance run:
-+
-+        cryptotest 100 4096
-+
-+    There are more options to cryptotest,  see the help.
-+
-+    It is also possible to use openssl to test the speed of the crypto
-+    drivers.
-+
-+        openssl speed -evp des -engine cryptodev -elapsed
-+        openssl speed -evp des3 -engine cryptodev -elapsed
-+        openssl speed -evp aes128 -engine cryptodev -elapsed
-+
-+    and multiple threads (10) with:
-+
-+        openssl speed -evp des -engine cryptodev -elapsed -multi 10
-+        openssl speed -evp des3 -engine cryptodev -elapsed -multi 10
-+        openssl speed -evp aes128 -engine cryptodev -elapsed -multi 10
-+
-+    for public key testing you can try:
-+
-+        cryptokeytest
-+        openssl speed -engine cryptodev rsa -elapsed
-+        openssl speed -engine cryptodev dsa -elapsed

-+ * ---------------------------------------------------------------------------
-+ *
-+ * NOTES:
-+ *
-+ * The Freescale SEC (also known as 'talitos') resides on the
-+ * internal bus, and runs asynchronous to the processor core.  It has
-+ * a wide gamut of cryptographic acceleration features, including single-
-+ * pass IPsec (also known as algorithm chaining).  To properly utilize 
-+ * all of the SEC's performance enhancing features, further reworking 
-+ * of higher level code (framework, applications) will be necessary.
-+ *
-+ * The following table shows which SEC version is present in which devices:
-+ * 
-+ * Devices       SEC version
-+ *
-+ * 8272, 8248    SEC 1.0
-+ * 885, 875      SEC 1.2
-+ * 8555E, 8541E  SEC 2.0
-+ * 8349E         SEC 2.01
-+ * 8548E         SEC 2.1
-+ *
-+ * The following table shows the features offered by each SEC version:
-+ *
-+ * 	                       Max.   chan-
-+ * version  Bus I/F       Clock  nels  DEU AESU AFEU MDEU PKEU RNG KEU

-+ * SEC 1.2  internal 32b   66MHz   1     1    1    0    1    0   0   0
-+ * SEC 2.0  internal 64b  166MHz   4     1    1    1    1    1   1   0
-+ * SEC 2.01 internal 64b  166MHz   4     1    1    1    1    1   1   0
-+ * SEC 2.1  internal 64b  333MHz   4     1    1    1    1    1   1   1
-+ *
-+ * Each execution unit in the SEC has two modes of execution; channel and
-+ * slave/debug.  This driver employs the channel infrastructure in the
-+ * device for convenience.  Only the RNG is directly accessed due to the
-+ * convenience of its random fifo pool.  The relationship between the
-+ * channels and execution units is depicted in the following diagram:
-+ *
-+ *    -------   ------------
-+ * ---| ch0 |---|          |
-+ *    -------   |          |
-+ *              |          |------+-------+-------+-------+------------
-+ *    -------   |          |      |       |       |       |           |
-+ * ---| ch1 |---|          |      |       |       |       |           |
-+ *    -------   |          |   ------  ------  ------  ------      ------
-+ *              |controller|   |DEU |  |AESU|  |MDEU|  |PKEU| ...  |RNG |

-+ * ---| ch2 |---|          |      |       |       |       |           |
-+ *    -------   |          |      |       |       |       |           |
-+ *              |          |------+-------+-------+-------+------------
-+ *    -------   |          |
-+ * ---| ch3 |---|          |
-+ *    -------   ------------
-+ *
-+ * Channel ch0 may drive an aes operation to the aes unit (AESU),
-+ * and, at the same time, ch1 may drive a message digest operation
-+ * to the mdeu. Each channel has an input descriptor FIFO, and the 
-+ * FIFO can contain, e.g. on the 8541E, up to 24 entries, before a
-+ * a buffer overrun error is triggered. The controller is responsible
-+ * for fetching the data from descriptor pointers, and passing the 
-+ * data to the appropriate EUs. The controller also writes the 
-+ * cryptographic operation's result to memory. The SEC notifies 
-+ * completion by triggering an interrupt and/or setting the 1st byte 
-+ * of the hdr field to 0xff.
-+ *
-+ * TODO:
-+ * o support more algorithms
-+ * o support more versions of the SEC
-+ * o add support for linux 2.4
-+ * o scatter-gather (sg) support
-+ * o add support for public key ops (PKEU)
-+ * o add statistics

-+	  YAFFS2, or Yet Another Flash Filing System, is a filing system
-+	  optimised for NAND Flash chips.
-+
-+	  To compile the YAFFS2 file system support as a module, choose M
-+	  here: the module will be called yaffs2.
-+
-+	  If unsure, say N.
-+
-+	  Further information on YAFFS2 is available at

-+	depends on YAFFS_FS
-+	default y
-+	help
-+	  Enable YAFFS1 support -- yaffs for 512 byte / page devices
-+
-+	  Not needed for 2K-page devices.
-+
-+	  If unsure, say Y.
-+
-+config YAFFS_9BYTE_TAGS
-+	bool "Use older-style on-NAND data format with pageStatus byte"
-+	depends on YAFFS_YAFFS1
-+	default n
-+	help
-+
-+	  Older-style on-NAND data format has a "pageStatus" byte to record
-+	  chunk/page state.  This byte is zero when the page is discarded.
-+	  Choose this option if you have existing on-NAND data using this
-+	  format that you need to continue to support.  New data written
-+	  also uses the older-style format.  Note: Use of this option
-+	  generally requires that MTD's oob layout be adjusted to use the
-+	  older-style format.  See notes on tags formats and MTD versions
-+	  in yaffs_mtdif1.c.
-+
-+	  If unsure, say N.
-+
-+config YAFFS_DOES_ECC
-+	bool "Lets Yaffs do its own ECC"
-+	depends on YAFFS_FS && YAFFS_YAFFS1 && !YAFFS_9BYTE_TAGS
-+	default n
-+	help
-+	  This enables Yaffs to use its own ECC functions instead of using
-+	  the ones from the generic MTD-NAND driver.
-+
-+	  If unsure, say N.
-+
-+config YAFFS_ECC_WRONG_ORDER
-+	bool "Use the same ecc byte order as Steven Hill's nand_ecc.c"
-+	depends on YAFFS_FS && YAFFS_DOES_ECC && !YAFFS_9BYTE_TAGS
-+	default n
-+	help
-+	  This makes yaffs_ecc.c use the same ecc byte order as Steven
-+	  Hill's nand_ecc.c. If not set, then you get the same ecc byte
-+	  order as SmartMedia.
-+
-+	  If unsure, say N.
-+
-+config YAFFS_YAFFS2
-+	bool "2048 byte (or larger) / page devices"
-+	depends on YAFFS_FS
-+	default y
-+	help
-+	  Enable YAFFS2 support -- yaffs for >= 2K bytes per page devices

-+
-+config YAFFS_AUTO_YAFFS2
-+	bool "Autoselect yaffs2 format"
-+	depends on YAFFS_YAFFS2
-+	default y
-+	help
-+	  Without this, you need to explicitely use yaffs2 as the file
-+	  system type. With this, you can say "yaffs" and yaffs or yaffs2
-+	  will be used depending on the device page size (yaffs on
-+	  512-byte page devices, yaffs2 on 2K page devices).
-+
-+	  If unsure, say Y.
-+
-+config YAFFS_DISABLE_LAZY_LOAD
-+	bool "Disable lazy loading"
-+	depends on YAFFS_YAFFS2
-+	default n
-+	help
-+	  "Lazy loading" defers loading file details until they are
-+	  required. This saves mount time, but makes the first look-up
-+	  a bit longer.
-+
-+	  Lazy loading will only happen if enabled by this option being 'n'
-+	  and if the appropriate tags are available, else yaffs2 will
-+	  automatically fall back to immediate loading and do the right
-+	  thing.
-+
-+	  Lazy laoding will be required by checkpointing.
-+
-+	  Setting this to 'y' will disable lazy loading.
-+
-+	  If unsure, say N.
-+
-+
-+config YAFFS_DISABLE_WIDE_TNODES
-+	bool "Turn off wide tnodes"
-+	depends on YAFFS_FS
-+	default n
-+	help
-+	  Wide tnodes are only used for NAND arrays >=32MB for 512-byte
-+	  page devices and >=128MB for 2k page devices. They use slightly
-+	  more RAM but are faster since they eliminate chunk group
-+	  searching.
-+
-+	  Setting this to 'y' will force tnode width to 16 bits and save
-+	  memory but make large arrays slower.
-+
-+	  If unsure, say N.
-+
-+config YAFFS_ALWAYS_CHECK_CHUNK_ERASED
-+	bool "Force chunk erase check"
-+	depends on YAFFS_FS
-+	default n
-+	help
-+          Normally YAFFS only checks chunks before writing until an erased
-+	  chunk is found. This helps to detect any partially written
-+	  chunks that might have happened due to power loss.
-+
-+	  Enabling this forces on the test that chunks are erased in flash
-+	  before writing to them. This takes more time but is potentially
-+	  a bit more secure.
-+
-+	  Suggest setting Y during development and ironing out driver
-+	  issues etc. Suggest setting to N if you want faster writing.
-+
-+	  If unsure, say Y.
-+
-+config YAFFS_SHORT_NAMES_IN_RAM
-+	bool "Cache short names in RAM"
-+	depends on YAFFS_FS
-+	default y
-+	help
-+	  If this config is set, then short names are stored with the
-+	  yaffs_Object.  This costs an extra 16 bytes of RAM per object,
-+	  but makes look-ups faster.
-+
-+	  If unsure, say Y.
